Methods: A Japanese woman with a history of DPB experienced disease recurrence following bilateral LTx. Persistent colonization by P. aeruginosa and recurrent respiratory symptoms were observed. Off-label TSI therapy, commonly used in cystic fibrosis, was introduced. Clinical response was assessed through radiologic imaging, bronchoscopy, and microbiological cultures.
Results: TSI administration led to significant clinical and radiological improvement. P. aeruginosa was eradicated from sputum cultures within one month and remained absent throughout six months of follow-up. No hospitalizations or adverse events were reported during therapy.
Conclusion: This case suggests the potential of TSI as a therapeutic approach for managing recurrent DPB and indicates its role in stabilizing post-transplant outcomes. Further studies may clarify its efficacy and expand its application in broader DPB management strategies. en-copyright= kn-copyright= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin

en-title= kn-title=Chromosome-specific barcode system with centromeric repeat in cultivated soybean and wild progenitor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Wild soybean Glycine soja is the progenitor of cultivated soybean Glycine max. Information on soybean functional centromeres is limited despite extensive genome analysis. These species are an ideal model for studying centromere dynamics for domestication and breeding. We performed a detailed chromatin immunoprecipitation analysis using centromere-specific histone H3 protein to delineate two distinct centromeric DNA sequences with unusual repeating units with monomer sizes of 90–92 bp (CentGm-1) and 413-bp (CentGm-4) shorter and longer than standard nucleosomes. These two unrelated DNA sequences with no sequence similarity are part of functional centromeres in both species. Our results provide a comparison of centromere properties between a cultivated and a wild species under the effect of the same kinetochore protein. Possible sequence homogenization specific to each chromosome could highlight the mechanism for evolutionary conservation of centromeric properties independent of domestication and breeding. Moreover, a unique barcode system to track each chromosome is developed using CentGm-4 units. Our results with a unifying centromere composition model using CentGm-1 and CentGm-4 superfamilies could have far-reaching implications for comparative and evolutionary genome research. en-copyright= kn-copyright= en-aut-name=TekAhmet L en-aut-sei=Tek en-aut-mei=Ahmet L kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagakiKiyotaka en-aut-sei=Nagaki en-aut-mei=Kiyotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=Yıldız AkkamışHümeyra en-aut-sei=Yıldız Akkamış en-aut-mei=Hümeyra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaKeisuke en-aut-sei=Tanaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiHisato en-aut-sei=Kobayashi en-aut-mei=Hisato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Agricultural Genetic Engineering, Ayhan Şahenk Faculty of Agricultural Sciences and Technologies, Niğde Ömer Halisdemir University kn-affil= affil-num=2 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=3 en-affil=Department of Agricultural Genetic Engineering, Ayhan Şahenk Faculty of Agricultural Sciences and Technologies, Niğde Ömer Halisdemir University kn-affil= affil-num=4 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=5 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=4 article-no= start-page=715 end-page=721 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250213 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Telemedicine as an alternative to in-person care in the field of rheumatic diseases: A systematic scoping review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The COVID-19 pandemic prompted the widespread adoption of telemedicine as an alternative to in-person care. This systematic scoping review evaluated the effectiveness, cost-efficiency, and challenges of telemedicine for patients with rheumatic diseases.
Methods: A comprehensive search of the MEDLINE database was conducted using specific terms related to rheumatoid or juvenile arthritis, and telemedicine. The literature search included studies published up to March, 2024. In this review, we only considered studies assessing telemedicine as an alternative to in-person care.
Results: The search, conducted on 15 March 2024, generated 258 references. Eight reports from three randomized controlled trials and three observational studies were included. Randomized controlled trials have shown that the outcomes of telemedicine intervention are comparable to those of in-person care in terms of disease activity, functional status, and quality of life, while enabling fewer outpatient visits and cost-effectiveness. However, the high dropout rates highlight the importance of patient preferences and comprehensive education. Observational studies revealed similar findings but were limited by a high confounding bias.
Conclusion: Telemedicine offers economic advantages and maintains clinical outcomes comparable to those of in-person care. Its success depends on structured patient education and alignment with patient preferences. Further research is required, particularly in the context of healthcare in Japan. en-copyright= kn-copyright= en-aut-name=SadaKen-ei en-aut-sei=Sada en-aut-mei=Ken-ei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwataShigeru en-aut-sei=Iwata en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoueYuzaburo en-aut-sei=Inoue en-aut-mei=Yuzaburo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaEiichi en-aut-sei=Tanaka en-aut-mei=Eiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KawahitoYutaka en-aut-sei=Kawahito en-aut-mei=Yutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeAsami en-aut-sei=Abe en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawakamiAtsushi en-aut-sei=Kawakami en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyamaeTakako en-aut-sei=Miyamae en-aut-mei=Takako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Clinical Epidemiology, Kochi Medical School kn-affil= affil-num=2 en-affil=Department of Rheumatology and Clinical Immunology, Wakayama Medical University kn-affil= affil-num=3 en-affil=Department of General Medical Science, Graduate School of Medicine, Chiba University kn-affil= affil-num=4 en-affil=Department of Rheumatology, Tokyo Women’s Medical University School of Medicine kn-affil= affil-num=5 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Inflammation and Immunology, Graduate School of Medical Science, Kyoto Prefectural University of Medicine kn-affil= affil-num=7 en-affil=Department of Rheumatology, Niigata Rheumatic Center kn-affil= affil-num=8 en-affil=Department of Immunology and Rheumatology, Division of Advanced Preventive Medical Sciences, Nagasaki University Graduate School of Biomedical Sciences kn-affil= affil-num=9 en-affil=Department of Pediatric Rheumatology, Institute of Rheumatology, Tokyo Women’s Medical University kn-affil= en-keyword=Digital health kn-keyword=Digital health en-keyword=telemedicine kn-keyword=telemedicine en-keyword=remote care kn-keyword=remote care en-keyword=rheumatic disease kn-keyword=rheumatic disease en-keyword=scoping review kn-keyword=scoping review END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=24 article-no= start-page=3299 end-page=3306 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241215 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Preliminary Survey of Rheumatologists on the Management of Late-onset Rheumatoid Arthritis in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective We investigated the current perspectives regarding the management of late-onset rheumatoid arthritis (LORA) among rheumatologists in clinical practice.
Methods This study was performed in October 2021, and included 65 rheumatologists certified by the Japan College of Rheumatology, who were administered questionnaires (including multiple choice and descriptive formulae) regarding the management of LORA. We aggregated and analyzed the responses.
Results All 65 rheumatologists responded to the survey; 47 (72%) answered that >50% of newly diagnosed patients were aged ≥65 years, 42 (65%) answered that achievement of remission or low disease activity was the treatment goal, and 40 (62%) considered patient safety to be the highest priority. Most rheumatologists are concerned about the management of conditions other than RA, such as comorbidities, financial constraints, and life circumstances that interfere with standard or recommended treatment implementation.
Conclusion This preliminary survey highlighted various rheumatologists' perspectives regarding the management of LORA. en-copyright= kn-copyright= en-aut-name=TakanashiSatoshi en-aut-sei=Takanashi

Children With Mental Health Disorders: Prospective, Single-Arm, Uncontrolled Clinical Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The prevalence of mental health disorders among children in Japan has increased rapidly, and these children often show depressive symptoms and reduced quality of life (QOL). We previously developed a smartphone-based self-monitoring app to deliver cognitive behavioral therapy (CBT), implemented it in healthy children, and reported its effectiveness for health promotion.
Objective: This study aims to examine the usefulness of the CBT app for improvement in depressive symptoms and QOL in children with mental health disorders.
Methods: The participants were 115 children with mental health disorders (eg, school refusal, orthostatic hypotension, eating disorders, developmental disorders, among others) and aged 12‐18 years. The CBT app–based program comprised 1 week of psychoeducation followed by 1 week of self-monitoring. After reading story-like scenarios, participants created a self-monitoring sheet with 5 panels: events, thoughts, feelings, body responses, and actions. All participants received regular mental health care from physicians in addition to the app-based program. To evaluate the participants’ depressive symptoms and QOL, Patient Health Questionnaire for Adolescents (PHQ-9A), Depression Self-Rating Scale for Children (DSRS-C), and Pediatric Quality of Life Inventory (PedsQL) were measured at the beginning of the intervention, and at 2 and 6 months thereafter. Questionnaire for Triage and Assessment with 30 items (QTA30), and Rosenberg Self-Esteem Scale (RSES) were also used to measure their health and self-esteem. Participants were divided into 4 groups on the basis of the PHQ-9A score (above or below the cutoff; PHQ-9A≥5 or PHQ-9A<5) and completion or noncompletion of the CBT app–based program (app [+] or app [-]). The primary outcome was improvement in the DSRS-C score, and secondary outcomes were improvement in other psychometric scales including PedsQL, QTA30, and RSE. A paired-samples t test was used for statistical analysis. The Medical Ethics Committee of Fukuoka University Faculty of Medicine (approval U22-05-002) approved the study design.
Results: There were 48, 18, 18, and 7 participants in the PHQ-9A≥5 app (+), PHQ-9A≥5 app (-), PHQ-9A<5 app (+), and PHQ-9A<5 app (-) groups, respectively. A total of 24 participants dropped out. No improvement in the DSRS-C score was observed in all groups. However, PedsQL scores improved significantly at 2 and 6 months in the PHQ-9A<5 app (+) group (t17=6.62; P<.001 and t17=6.11; P<.001, respectively). There was a significant positive correlation between the PHQ-9A scores and the number of self-monitoring sheets completed.
Conclusions: The CBT app was useful for improving PedsQL scores of children with mental health disorders. However, a higher-intensity CBT program is necessary for more severely depressed children.

Endoscopic Morphological Changes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Atypical lipomatous tumor/well-differentiated liposarcoma is a locally aggressive mesenchymal neoplasm composed of adipocytes and stromal cells. Gastric cases are exceedingly rare, and their malignant potential remains unclear. We report a case of a woman in her 60s who was found to have multiple submucosal tumor-like lesions of the stomach. Over time, the tumors increased in size, requiring a laparoscopic partial gastrectomy. Histological examination revealed a tumor composed of both fatty tissue and fibrous stroma with nuclear atypia. Immunohistochemistry showed positivity for CDK4 and MDM2, and fluorescence in situ hybridization confirmed MDM2 amplification, leading to a diagnosis of atypical lipomatous tumor/well-differentiated liposarcoma. This case presented an unusual gastric manifestation, with multiple submucosal tumor-like lesions on endoscopy and exhibiting progressive morphological changes over several years. en-copyright= kn-copyright= en-aut-name=OmoteRika en-aut-sei=Omote en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OmoteShizuma en-aut-sei=Omote en-aut-mei=Shizuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SonobeHiroshi en-aut-sei=Sonobe en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HamanoRyosuke en-aut-sei=Hamano en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InagakiMasaru en-aut-sei=Inagaki en-aut-mei=Masaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamamotoHidetaka en-aut-sei=Yamamoto en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Diagnostic Pathology, NHO Fukuyama Medical Center kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Fukuyama Minami Hospital kn-affil= affil-num=3 en-affil=Department of Diagnostic Pathology, NHO Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=5 en-affil=Department of Gastroenterology, NHO Fukuyama Medical Center kn-affil= affil-num=6 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=7 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=10 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=atypical lipomatous tumor kn-keyword=atypical lipomatous tumor en-keyword=CDK4 kn-keyword=CDK4 en-keyword=MDM2 kn-keyword=MDM2 en-keyword=stomach kn-keyword=stomach en-keyword=well-differentiated liposarcoma kn-keyword=well-differentiated liposarcoma END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=594 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Review Article: Diagnostic Paradigm Shift in Spine Surgery en-subtitle= kn-subtitle= en-abstract= kn-abstract=Meticulous clinical examination is essential for spinal disorders to utilize the diagnostic methods and technologies that strongly support physicians and enhance clinical practice. A significant change in the approach to diagnosing spinal disorders has occurred in the last three decades, which has enhanced a more nuanced understanding of spine pathology. Traditional radiographic methods such as conventional and functional X-rays and CT scans are still the first line in the diagnosis of spinal disorders due to their low cost and accessibility. As more advanced imaging technologies become increasingly available worldwide, there is a constantly increasing trend in MRI scans for detecting spinal pathologies and making treatment decisions. Not only do MRI scans have superior diagnostic capabilities, but they also assist surgeons in performing meticulous preoperative planning, making them currently the most widely used diagnostic tool for spinal disorders. Positron Emission Tomography (PET) can help detect inflammatory lesions, infections, and tumors. Other advanced diagnostic tools such as CT/MRI fusion image, Functional Magnetic Resonance Imaging (fMRI), Upright and Kinetic MRI, magnetic resonance spectroscopy (MRS), diffusion-weighted imaging (DWI), and diffusion tensor imaging (DTI) could play an important role when it comes to detecting more special pathologies. However, some technical difficulties in the daily praxis and their high costs act as obstacles to their further spread. Integrating artificial intelligence and advancements in data analytics and virtual reality promises to enhance spinal procedures’ precision, safety, and efficacy. As these technologies continue to develop, they will play a critical role in transforming spinal surgery. This paradigm shift emphasizes the importance of continuous innovation and adaptability in improving the diagnosis and treatment of spinal disorders. en-copyright= kn-copyright= en-aut-name=LeventAras Efe en-aut-sei=Levent en-aut-mei=Aras Efe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HengChristian en-aut-sei=Heng en-aut-mei=Christian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NikolaosSalamalikis en-aut-sei=Nikolaos en-aut-mei=Salamalikis kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LatkaKajetan en-aut-sei=Latka en-aut-mei=Kajetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=diagnosis kn-keyword=diagnosis en-keyword=spine surgery kn-keyword=spine surgery en-keyword=innovative technique kn-keyword=innovative technique en-keyword=MRI kn-keyword=MRI en-keyword=myelography kn-keyword=myelography END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=4 article-no= start-page=616 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Novel Technique for Basilar Invagination Treatment in a Patient with Klippel–Feil Syndrome: A Clinical Example and Brief Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives and Background: To present a novel technique of treatment for a patient with basilar invagination. Basilar invagination (BI) is a congenital condition that can compress the cervicomedullary junction, leading to neurological deficits. Severe cases require surgical intervention, but there is debate over the choice of approach. The anterior approach allows direct decompression but carries high complication rates, while the posterior approach provides indirect decompression and offers good stability with fewer complications. Materials and Methods: A 15-year-old boy with severe myelopathy presented to our hospital with neck pain, bilateral upper limb muscle weakness, and hand numbness persisting for 4 years. Additionally, he experienced increased numbness and gait disturbance three months before his visit. On examination, he exhibited hyperreflexia in both upper and lower limbs, muscle weakness in the bilateral upper limbs (MMT 4), bilateral hypoesthesia below the elbow and in both legs, mild urinary and bowel incontinence, and a spastic gait. Radiographs revealed severe basilar invagination (BI). Preoperative images showed severe BI and that the spinal cord was severely compressed with odontoid process. Results: The patient underwent posterior surgery with the C-arm free technique. All screws including occipital screws were inserted into the adequate position under navigation guidance. Reduction was achieved with skull rotation and distraction. A follow-up at one year showed the following results: Manual muscle testing results and sensory function tests showed almost full recovery, with bilateral arm recovery (MMT 5) and smooth walking. The cervical Japanese Orthopedic Association score of the patient improved from 9/17 to 16/17. Postoperative images showed excellent spinal cord decompression, and no major or severe complications had occurred. Conclusions: Basilar invagination alongside Klippel–Feil syndrome represents a relatively uncommon condition. Utilizing a posterior approach for treating reducible BI with a C-arm-free technique proved to be a safe method in addressing severe myelopathy. This novel navigation technique yields excellent outcomes for patients with BI. en-copyright= kn-copyright= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AskarAbd El Kader Al en-aut-sei=Askar en-aut-mei=Abd El Kader Al kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=basilar invagination kn-keyword=basilar invagination en-keyword=Klippel–Feil syndrome kn-keyword=Klippel–Feil syndrome en-keyword=navigation kn-keyword=navigation en-keyword=C-arm free kn-keyword=C-arm free en-keyword=novel technique kn-keyword=novel technique END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=23 article-no= start-page=2715 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Predicting Surgical Site Infections in Spine Surgery: Association of Postoperative Lymphocyte Reduction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: Postoperative lymphopenia is reported as an excellent indicator to predict surgical-site infection (SSI) after spine surgery. However, there is still controversy concerning which serological markers can predict spinal SSI. This study aims to evaluate excellent and early indicators for detecting SSI, focusing on spine instrumented surgery. Materials and Methods: This study included 268 patients who underwent spinal instrumented surgery from January 2022 to December 2023 (159 female and 109 male, average 62.9 years). The SSI group included 20 patients, and the non-SSI group comprised 248 patients. Surgical time, intraoperative blood loss, and glycemic levels were measured in both groups. The complete blood cell counts, differential counts, albumin, and C-reactive protein (CRP) levels were measured pre-surgery and postoperative on Days 1, 3, and 7. In comparing the groups, the Mann–Whitney U test analysis was used for continuous variables, while the chi-squared test and Fisher’s exact test were used for dichotomous variables. Results: The incidence of SSI after spinal instrumentation was 7.46% and was relatively higher in scoliosis surgery. The SSI group had significantly longer surgical times (248 min vs. 180 min, p = 0.0004) and a higher intraoperative blood loss (772 mL vs. 372 mL, p < 0.0001) than the non-SSI group. In the SSI group, the Day 3 (10.5 ± 6.2% vs. 13.8 ± 6.0%, p = 0.012) and Day 7 (14.4 ± 4.8% vs. 18.8 ± 7.1%, p = 0.012) lymphocyte ratios were lower than the non-SSI group. Albumin levels on Day 1 in the SSI group were lower than in the non-SSI group (2.94 ± 0.30 mg/dL vs. 3.09 ± 0.38 mg/dL, p = 0.045). There is no difference in CRP and lymphocyte count between the two groups. Conclusions: SSI patients had lower lymphocyte percentages than non-SSI patients, which was a risk factor for SSI, with constant high inflammation. The Day 3 lymphocyte percentage may predict SSI after spinal instrumented surgery. en-copyright= kn-copyright= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FloresAngel Oscar Paz en-aut-sei=Flores en-aut-mei=Angel Oscar Paz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YuDongwoo en-aut-sei=Yu en-aut-mei=Dongwoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=JainMukul en-aut-sei=Jain en-aut-mei=Mukul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HengChristan en-aut-sei=Heng en-aut-mei=Christan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= en-keyword=surgical site infection kn-keyword=surgical site infection en-keyword=spine surgery kn-keyword=spine surgery en-keyword=instrumentation kn-keyword=instrumentation en-keyword=diagnosis kn-keyword=diagnosis en-keyword=lymphocyte kn-keyword=lymphocyte END start-ver=1.4 cd-journal=joma no-vol=60 cd-vols= no-issue=4 article-no= start-page=519 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240322 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Retrospective Cohort Study of Early versus Delayed Ballon Kyphoplasty Intervention for Osteoporotic Vertebral Fracture Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: To investigate the outcomes of early balloon kyphoplasty (BKP) intervention compared with late intervention for osteoporotic vertebral fracture (OVF). Background: Osteoporotic vertebral fracture can lead to kyphotic deformity, severe back pain, depression, and disturbances in activities of daily living (ADL). Balloon kyphoplasty has been widely utilized to treat symptomatic OVFs and has proven to be a very effective surgical option for this condition. Furthermore, BKP is relatively a safe and effective method due to its reduced acrylic cement leakage and greater kyphosis correction. Materials and Methods: A retrospective cohort study was conducted at our hospital for patients who underwent BKP for osteoporotic vertebral fractures in the time frame between January 2020 and December 2022. Ninety-nine patients were included in this study, and they were classified into two groups: in total, 36 patients underwent early BKP intervention (EI) at <4 weeks, and 63 patients underwent late BKP intervention (LI) at ≥4 weeks. We performed a clinical, radiological and statistical comparative evaluation for the both groups with a mean follow-up of one year. Results: Adjacent segmental fractures were more frequently observed in the LI group compared to the EI group (33.3% vs. 13.9%, p = 0.034). There was a significant improvement in postoperative vertebral angles in both groups (p = 0.036). The cement volume injected was 7.42 mL in the EI, compared with 6.3 mL in the LI (p = 0.007). The mean surgery time was shorter in the EI, at 30.2 min, compared with 37.1 min for the LI, presenting a significant difference (p = 0.0004). There was no statistical difference in the pain visual analog scale (VAS) between the two groups (p = 0.711), and there was no statistical difference in cement leakage (p = 0.192). Conclusions/Level of Evidence: Early BKP for OVF treatment may achieve better outcomes and fewer adjacent segmental fractures than delayed intervention. en-copyright= kn-copyright= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=PariharUmesh en-aut-sei=Parihar en-aut-mei=Umesh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=El Kader Al AskarAbd en-aut-sei=El Kader Al Askar en-aut-mei=Abd kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GunjotikarSharvari en-aut-sei=Gunjotikar en-aut-mei=Sharvari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= en-keyword=ballon kyphoplasty kn-keyword=ballon kyphoplasty en-keyword=osteoporotic vertebral fractures kn-keyword=osteoporotic vertebral fractures en-keyword=kyphosis kn-keyword=kyphosis END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=1 article-no= start-page=e70040 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250514 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Avoidant/restrictive food intake disorder prognosis and its relation with autism spectrum disorder in Japanese children en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: There is a lack of reported clinical factors associated with the outcomes of children and adolescents with avoidant/restrictive food intake disorder (ARFID) in Japan. This study aimed to identify these clinical factors and explore the relationship between ARFID and autism spectrum disorder (ASD).
Methods: This retrospective study analyzed data from 48 Japanese children and adolescents with ARFID who visited Okayama University Hospital between January 2011 and March 2022. Clinical characteristics were assessed using medical records and natural history questionnaires. The study compared patients with good and poor prognosis groups and used multiple logistic regression analysis to determine factors influencing prognosis.
Results: The study included 33 patients with good prognoses and 15 with poor prognoses. Comorbid ASD was more prevalent in the poor prognosis group (60%) compared to the good prognosis group (21%). Additionally, more than half of the ARFID patients with comorbid ASD were initially undiagnosed. Multivariate analysis revealed that older age at first visit (p = 0.022) and comorbid ASD (p = 0.022) were statistically significant factors associated with poor prognosis in ARFID patients. There were no significant differences in body mass index standard deviation score and maximal weight loss between the two groups.
Conclusions: The poor prognosis group had a higher prevalence of comorbid ASD diagnoses. Therefore, it is crucial to evaluate patient's developmental characteristics early in treatment and consider these characteristics throughout the course of care. en-copyright= kn-copyright= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HanzawaMana en-aut-sei=Hanzawa en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigeyasuYoshie en-aut-sei=Shigeyasu en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoriuchiMakiko en-aut-sei=Horiuchi en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Clinical Psychology Section, Department of Medical Support, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=autism spectrum disorder kn-keyword=autism spectrum disorder en-keyword=avoidant/restrictive food intake disorder kn-keyword=avoidant/restrictive food intake disorder en-keyword=children kn-keyword=children en-keyword=feeding and eating disorders kn-keyword=feeding and eating disorders en-keyword=outcome kn-keyword=outcome END start-ver=1.4 cd-journal=joma no-vol=47 cd-vols= no-issue=6 article-no= start-page=466 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250617 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Artificial Intelligence Approach in Machine Learning-Based Modeling and Networking of the Coronavirus Pathogenesis Pathway en-subtitle= kn-subtitle= en-abstract= kn-abstract=The coronavirus pathogenesis pathway, which consists of severe acute respiratory syndrome (SARS) coronavirus infection and signaling pathways, including the interferon pathway, the transforming growth factor beta pathway, the mitogen-activated protein kinase pathway, the apoptosis pathway, and the inflammation pathway, is activated upon coronaviral infection. An artificial intelligence approach based on machine learning was utilized to develop models with images of the coronavirus pathogenesis pathway to predict the activation states. Data on coronaviral infection held in a database were analyzed with Ingenuity Pathway Analysis (IPA), a network pathway analysis tool. Data related to SARS coronavirus 2 (SARS-CoV-2) were extracted from more than 100,000 analyses and datasets in the IPA database. A total of 27 analyses, including nine analyses of SARS-CoV-2-infected human-induced pluripotent stem cells (iPSCs) and iPSC-derived cardiomyocytes and fibroblasts, and a total of 22 analyses of SARS-CoV-2-infected lung adenocarcinoma (LUAD), were identified as being related to “human” and “SARS coronavirus 2” in the database. The coronavirus pathogenesis pathway was activated in SARS-CoV-2-infected iPSC-derived cells and LUAD cells. A prediction model was developed in Python 3.11 using images of the coronavirus pathogenesis pathway under different conditions. The prediction model of activation states of the coronavirus pathogenesis pathway may aid in treatment identification. en-copyright= kn-copyright= en-aut-name=TanabeShihori en-aut-sei=Tanabe en-aut-mei=Shihori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=QuaderSabina en-aut-sei=Quader en-aut-mei=Sabina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoRyuichi en-aut-sei=Ono en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaHiroyoshi Y. en-aut-sei=Tanaka en-aut-mei=Hiroyoshi Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoAkihisa en-aut-sei=Yamamoto en-aut-mei=Akihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KojimaMotohiro en-aut-sei=Kojima en-aut-mei=Motohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=PerkinsEdward J. en-aut-sei=Perkins en-aut-mei=Edward J. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=CabralHoracio en-aut-sei=Cabral en-aut-mei=Horacio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Risk Assessment, Center for Biological Safety and Research, National Institute of Health Sciences kn-affil= affil-num=2 en-affil=Innovation Centre of NanoMedicine (iCONM), Kawasaki Institute of Industrial Promotion kn-affil= affil-num=3 en-affil=Division of Cellular and Molecular Toxicology, Center for Biological Safety and Research, National Institute of Health Sciences kn-affil= affil-num=4 en-affil=Department of Pharmaceutical Biomedicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Mechanical Systems Engineering, Graduate School of Systems Design Tokyo Metropolitan University kn-affil= affil-num=6 en-affil=Department of Surgical Pathology, Kyoto Prefecture University of Medicine kn-affil= affil-num=7 en-affil=US Army Engineer Research and Development Center kn-affil= affil-num=8 en-affil=Department of Bioengineering, Graduate School of Engineering, The University of Tokyo kn-affil= en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=coronavirus kn-keyword=coronavirus en-keyword=coronaviral infection kn-keyword=coronaviral infection en-keyword=machine learning kn-keyword=machine learning en-keyword=pathway analysis kn-keyword=pathway analysis en-keyword=predictionmodel kn-keyword=predictionmodel en-keyword=molecular network kn-keyword=molecular network en-keyword=molecular pathway image kn-keyword=molecular pathway image en-keyword=network analysis kn-keyword=network analysis END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=10 article-no= start-page=1444 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Canine c-kit Novel Mutation Isolated from a Gastrointestinal Stromal Tumor (GIST) Retains the Ability to Form Dimers but Lacks Autophosphorylation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors that develop in the gastrointestinal tract; KIT mutations are present in both canine and human GISTs. In this study, genomic DNA was extracted from formalin-fixed paraffin-embedded (FFPE) sections of 55 canine GIST cases, and mutation searches were performed for exons 8, 9, and 11. The results revealed novel mutations, A434T and F436S, in exon 8. In contrast to the A434T mutation without functional changes, the F436S mutant retained its dimerization ability, but lost its phosphorylation function and attenuated downstream Akt signaling, which is reflected in wound healing and migration activities. A comparison of the subcellular localization of WT KIT and the F436S mutant revealed no differences. In silico simulations indicated that the F436S mutation alters the structure of the near-membrane region and that its effects may extend to the transmembrane and intracellular domains compared to the WT. F436S is a point mutation that affects the entire molecule because co-mutation with the F436S mutation and the known autophosphorylation mutation reduces the autophosphorylation abilities. en-copyright= kn-copyright= en-aut-name=ShimakawaKei en-aut-sei=Shimakawa en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DogeSo en-aut-sei=Doge en-aut-mei=So kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MichishitaMasaki en-aut-sei=Michishita en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanabeEri en-aut-sei=Tanabe en-aut-mei=Eri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TajimaTsuyoshi en-aut-sei=Tajima en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KobayashiMasato en-aut-sei=Kobayashi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BonkobaraMakoto en-aut-sei=Bonkobara en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeMasami en-aut-sei=Watanabe en-aut-mei=Masami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OchiaiKazuhiko en-aut-sei=Ochiai en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaYoshikazu en-aut-sei=Tanaka en-aut-mei=Yoshikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=2 en-affil=Laboratory of Veterinary Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=3 en-affil=Laboratory of Veterinary Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=4 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=5 en-affil=Laboratory of Veterinary Pharmacology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=6 en-affil=Laboratory of Veterinary Reproduction, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=7 en-affil=Laboratory of Veterinary Clinical Pathology, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=8 en-affil=Laboratory of Urology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= affil-num=10 en-affil=Laboratory of Veterinary Hygiene, School of Veterinary Science, Nippon Veterinary and Life Science University kn-affil= en-keyword=autophosphorylation kn-keyword=autophosphorylation en-keyword=canine kn-keyword=canine en-keyword=c-kit kn-keyword=c-kit en-keyword=GIST kn-keyword=GIST en-keyword=KIT kn-keyword=KIT en-keyword=loss-of-function mutation kn-keyword=loss-of-function mutation END start-ver=1.4 cd-journal=joma no-vol=19 cd-vols= no-issue=3 article-no= start-page=444 end-page=451 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250630 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=More postoperative complications and revision surgery after occipitocervical fusion than after atlantoaxial fusion: a retrospective multicenter cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Study Design: A retrospective multicenter cohort study.
Purpose: We sought to determine whether occipitocervical (OC) fusion is followed by more postoperative complications and revision surgery than is atlantoaxial (AA) fusion. We aim to compare postoperative complications and revision surgery associated with OC fusion and AA fusion.
Overview of Literature: OC and AA fusion are established techniques for restoring upper cervical stability. However, the outcomes of the two methods have not been compared.
Methods: This study included 90 patients who underwent upper spinal fusion surgery for mechanical instability, performed by three surgeons in two hospitals from 2011 to 2023; OC fusion was indicated for irreducible AA subluxation, os odontoideum, and severe upper C1 fracture. Of the patients, 38 (mean age, 58.7 years) underwent OC fusion, and 52 (mean age, 62.8 years) underwent AA fusion. To evaluate surgical outcomes, we documented surgical time, intraoperative blood loss, postoperative complications, and the rate of revision surgery. Radiographs were obtained to identify screw malposition, rod breakage, and nonunion. To compare the outcomes of the two techniques, we used the Mann-Whitney U test for continuous variables and the chi-square or Fisher’s exact test for dichotomous variables.
Results: OC fusion took significantly longer (175.4 minutes) than AA fusion (150.7 minutes, p=0.020) and had a higher complication rate (39.5% vs. 11.5%, p<0.0001). The reoperation rate was 23.7% (9/38) after OC fusion and 3.8% (2/52) after AA fusion; the difference was statistically significant (p=0.0073). Average amounts of blood loss were 224 mL during OC fusion and 224 mL during AA fusion; the difference was not significant (p=0.947).
Conclusions: Although OC fusion is indispensable for certain conditions, particularly basilar invagination, it entails more risk than dose AA fusion; the choice of technique thus warrants careful consideration. en-copyright= kn-copyright= en-aut-name=UotaniKoji en-aut-sei=Uotani en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FloresAngel Oscar Paz en-aut-sei=Flores en-aut-mei=Angel Oscar Paz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EkadeShashank J en-aut-sei=Ekade en-aut-mei=Shashank J kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OdaYoshiaki en-aut-sei=Oda en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShinoharaKensuke en-aut-sei=Shinohara en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= en-keyword=Occipitocervical fusion kn-keyword=Occipitocervical fusion en-keyword=Atlantoaxial fusion kn-keyword=Atlantoaxial fusion en-keyword=Upper cervical instability kn-keyword=Upper cervical instability en-keyword=Surgical complication kn-keyword=Surgical complication en-keyword=Reoperation kn-keyword=Reoperation END start-ver=1.4 cd-journal=joma no-vol=37 cd-vols= no-issue=7 article-no= start-page=koaf142 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pancentromere analysis of Allium species reveals diverse centromere positions in onion and gigantic centromeres in garlic en-subtitle= kn-subtitle= en-abstract= kn-abstract=In eukaryotes, centromeres interact with the kinetochore for distribution of genetic information in cell division, yet their sequence and size are diverse among species. However, their position on chromosomes is considered to be conserved within a species. In this study, we analyzed the centromeres of 3 Allium species, namely, Welsh onion (Allium fistulosum), onion (Allium cepa), and garlic (Allium sativum) via pancentromere analysis and repetitive sequence analysis of centromeres and their neighborhoods and revealed their mobility, sequence organization, and size. Among the 3 species, Welsh onion and garlic had stable centromeres, but the onion centromere appeared to be polymorphic and frequently differed in position by up to 28.0 Mb among cultivars and between multiple individuals of the same cultivar. This mobility was stabilized by hybridization with Welsh onions. Furthermore, these 3 species have very different centromere sequence organization, including differences in the existence and maturity of centromeric satellites, and differences in centromere size, with Welsh onion having a centromere of 1.9 Mb, and garlic having a centromere of ∼10.6 Mb, the largest of any organism with monocentric chromosomes analyzed to date. Our pancentromere analysis of these Allium species reveals the variation in sequence organization, size, and position of this important chromosomal region. en-copyright= kn-copyright= en-aut-name=NagakiKiyotaka en-aut-sei=Nagaki en-aut-mei=Kiyotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UshijimaKoichiro en-aut-sei=Ushijima en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AkagiTakashi en-aut-sei=Akagi en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaKeisuke en-aut-sei=Tanaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiHisato en-aut-sei=Kobayashi en-aut-mei=Hisato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=5 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=7 article-no= start-page=e88945 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250728 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Six-Year Remission With No Relapse After Four-Time Weekly Rituximab Only for Bilateral Ocular Adnexal Follicular Lymphoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Follicular lymphoma mostly takes an indolent course, and thus, observation with watchful waiting is a main therapeutic strategy. Recent long-term studies suggest earlier treatment with rituximab monotherapy may benefit patients by delaying the need for treatment in the later phase of exacerbation. In this study, we reported a patient with bilateral orbital follicular lymphoma who received four-time weekly rituximab monotherapy as an induction therapy only and maintained the remission for 5 years with no treatment. The patient was a 51-year-old woman who developed a right upper orbital mass and was diagnosed with follicular lymphoma grade 1 by the excisional biopsy. Two years later, at the age of 53 years, she developed a left lacrimal gland mass and underwent excision. The pathological diagnosis was follicular lymphoma grade 1. She did not have any other systemic lesions by fluorodeoxyglucose positron emission tomography. At the age of 54 years, she developed a new mass on the nasal side of the right orbit and underwent weekly rituximab monotherapy (375 mg/m2) four times a month, leading to the reduction of the mass in 3 months. Two high uptake sites on the temporal and nasal side of the right superior orbit by fluorodeoxyglucose positron emission tomography disappeared one year later at the age of 55 years. She was followed with no treatment for 6 years until the age of 60 years at the latest visit. In case of a local orbital relapse, local radiotherapy would be the standard, but rituximab monotherapy as an induction therapy only was chosen in the present patient. Rituximab monotherapy in place of local radiotherapy would be a treatment option for orbital follicular lymphoma. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University, and Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Division of Transfusion and Cell Therapy, Department of Hematology and Oncology, Okayama University Hospital kn-affil= en-keyword=claustrophobia kn-keyword=claustrophobia en-keyword=extranodal marginal zone b-cell lymphoma mucosa-associated lymphoid tissue (malt) type kn-keyword=extranodal marginal zone b-cell lymphoma mucosa-associated lymphoid tissue (malt) type en-keyword=fluorodeoxyglucose positron emission tomography kn-keyword=fluorodeoxyglucose positron emission tomography en-keyword=follicular lymphoma kn-keyword=follicular lymphoma en-keyword=magnetic resonance imaging kn-keyword=magnetic resonance imaging en-keyword=mucosaassociated lymphoid tissue (malt) lymphoma kn-keyword=mucosaassociated lymphoid tissue (malt) lymphoma en-keyword=ocular adnexa kn-keyword=ocular adnexa en-keyword=orbital mass kn-keyword=orbital mass en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=rituximab kn-keyword=rituximab END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=5 article-no= start-page=e70046 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spider mite tetranins elicit different defense responses in different host habitats en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spider mites (Tetranychus urticae) are a major threat to economically important crops. Here, we investigated the potential of tetranins, in particular Tet3 and Tet4, as T. urticae protein-type elicitors that stimulate plant defense. Truncated Tet3 and Tet4 proteins showed efficacy in activating the defense gene pathogenesis-related 1 (PR1) and inducing phytohormone production in leaves of Phaseolus vulgaris. In particular, Tet3 caused a drastically higher Ca2+ influx in leaves, but a lower reactive oxygen species (ROS) generation compared to other tetranins, whereas Tet4 caused a low Ca2+ influx and a high ROS generation in the host plants. Such specific and non-specific elicitor activities were examined by knockdown of Tet3 and Tet4 expressions in mites, confirming their respective activities and in particular showing that they function additively or synergistically to induce defense responses. Of great interest is the fact that Tet3 and Tet4 expression levels were higher in mites on their preferred host, P. vulgaris, compared to the levels in mites on the less-preferred host, Cucumis sativus, whereas Tet1 and Tet2 were constitutively expressed regardless of their host. Furthermore, mites that had been hosted on C. sativus induced lower levels of PR1 expression, Ca2+ influx and ROS generation, i.e., Tet3- and Tet4-responsive defense responses, in both P. vulgaris and C. sativus leaves compared to the levels induced by mites that had been hosted on P. vulgaris. Taken together, these findings show that selected tetranins respond to variable host cues that may optimize herbivore fitness by altering the anti-mite response of the host plant. en-copyright= kn-copyright= en-aut-name=EndoYukiko en-aut-sei=Endo en-aut-mei=Yukiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaMiku en-aut-sei=Tanaka en-aut-mei=Miku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UemuraTakuya en-aut-sei=Uemura en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanimuraKaori en-aut-sei=Tanimura en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DesakiYoshitake en-aut-sei=Desaki en-aut-mei=Yoshitake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OzawaRika en-aut-sei=Ozawa en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BonzanoSara en-aut-sei=Bonzano en-aut-mei=Sara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MaffeiMassimo E. en-aut-sei=Maffei en-aut-mei=Massimo E. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ShinyaTomonori en-aut-sei=Shinya en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=GalisIvan en-aut-sei=Galis en-aut-mei=Ivan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ArimuraGen‐ichiro en-aut-sei=Arimura en-aut-mei=Gen‐ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=2 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=3 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=4 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=5 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= affil-num=6 en-affil=Center for Ecological Research, Kyoto University kn-affil= affil-num=7 en-affil=Department of Life Sciences and Systems Biology, Plant Physiology Unit, University of Turin kn-affil= affil-num=8 en-affil=Department of Life Sciences and Systems Biology, Plant Physiology Unit, University of Turin kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=10 en-affil=Institute of Plant Science and Resources (IPSR), Okayama University kn-affil= affil-num=11 en-affil=Department of Biological Science and Technology, Faculty of Advanced Engineering, Tokyo University of Science kn-affil= en-keyword=Cucumis sativus kn-keyword=Cucumis sativus en-keyword=elicitor kn-keyword=elicitor en-keyword=Phaseolus vulgaris kn-keyword=Phaseolus vulgaris en-keyword=spider mite (Tetranychus urticae) kn-keyword=spider mite (Tetranychus urticae) en-keyword=tetranin kn-keyword=tetranin END start-ver=1.4 cd-journal=joma no-vol=653 cd-vols= no-issue= article-no= start-page=119205 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Meteoritic and asteroidal amino acid heterogeneity: Implications for planetesimal alteration conditions and sample return missions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Carbonaceous chondrites (CC) and asteroid return samples contain amino acids (AA), which are essential for an origin of life on the early Earth and can provide important information concerning planetesimal alteration processes. While many studies have investigated AA from CC, separate studies have often found differing abundances for the same meteorite. Accordingly, analytical bias, differing terrestrial contamination levels and intrinsic sample heterogeneity have been proposed as potential reasons. However, current analytical techniques allow for the analysis of several mg-sized samples and can thus enable an investigation of AA heterogeneity within single meteorite specimens. Here, such an analytical technique is applied to characterise the AA in triplicate aliquots of three CCs. The results indicate that CCs are heterogenous in terms of their AA at the mm-scale. Furthermore, the results help to further constrain the effects of planetesimal alteration on organic matter and the requirements of future sample return missions that aim to obtain organic-bearing extraterrestrial materials. en-copyright= kn-copyright= en-aut-name=PotiszilChristian en-aut-sei=Potiszil en-aut-mei=Christian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaTsutomu en-aut-sei=Ota en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamanakaMasahiro en-aut-sei=Yamanaka en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KobayashiKatsura en-aut-sei=Kobayashi en-aut-mei=Katsura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaRyoji en-aut-sei=Tanaka en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraEizo en-aut-sei=Nakamura en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=4 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=5 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= affil-num=6 en-affil=Pheasant Memorial Laboratory, Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Carbonaceous chondrite kn-keyword=Carbonaceous chondrite en-keyword=Heterogeneity kn-keyword=Heterogeneity en-keyword=Planetesimal kn-keyword=Planetesimal en-keyword=Aqueous alteration kn-keyword=Aqueous alteration en-keyword=Amino acid and meteorite kn-keyword=Amino acid and meteorite END start-ver=1.4 cd-journal=joma no-vol=169 cd-vols= no-issue= article-no= start-page=155745 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202510 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Recent progress on phenothiazine organophotoredox catalysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photoredox catalysis has garnered significant attention in recent years due to its broad applicability in visible-light-induced organic transformations. While significant progress has been made in the development of highly oxidizing catalysts, such as acridinium catalysts, there remains a notable shortage of strongly reducing organophotoredox catalysts. Phenothiazines are widely used as photoredox catalysts owing to their unique redox potentials, particularly their low excited-state oxidation potentials (Eox* = −1.35 V to −3.51 V vs. SCE). Thus, they can be applied to a variety of photoredox reactions with oxidative-quenching cycles, and effectively reduce various organic molecules, such as aryl and alkyl halides, alkenes, malonyl peroxides, cobalt complexes, and redox-active esters. Due to their unique properties, this review focuses on the recent advances in phenothiazine organophotoredox catalysis. en-copyright= kn-copyright= en-aut-name=TanakaKenta en-aut-sei=Tanaka en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakamuraHiroyoshi en-aut-sei=Takamura en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= en-keyword=Phenothiazine kn-keyword=Phenothiazine en-keyword=Photoredox catalysis kn-keyword=Photoredox catalysis en-keyword=Visible light kn-keyword=Visible light en-keyword=Radical kn-keyword=Radical END start-ver=1.4 cd-journal=joma no-vol=965 cd-vols= no-issue=1 article-no= start-page=52 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Unraveling the Cr Isotopes of Ryugu: An Accurate Aqueous Alteration Age and the Least Thermally Processed Solar System Material en-subtitle= kn-subtitle= en-abstract= kn-abstract=The analysis of samples returned from the C-type asteroid Ryugu has drastically advanced our knowledge of the evolution of early solar system materials. However, no consensus has been obtained on the chronological data, which is important for understanding the evolution of the asteroid Ryugu. Here, the aqueous alteration age of Ryugu particles was determined by the Mn–Cr method using bulk samples, yielding an age of 4.13 + 0.62/−0.55 Myr after the formation of Ca–Al-rich inclusions (CAI). The age corresponds to 4563.17 + 0.60/−0.67 Myr ago. The higher 55Mn/52Cr, ε54Cr, and initial ε53Cr values of the Ryugu samples relative to any carbonaceous chondrite samples implies that its progenitor body formed from the least thermally processed precursors in the outermost region of the protoplanetary disk. Despite accreting at different distances from the Sun, the hydrous asteroids (Ryugu and the parent bodies of CI, CM, CR, and ungrouped C2 meteorites) underwent aqueous alteration during a period of limited duration (3.8 ± 1.8 Myr after CAI). These ages are identical to the crystallization age of the carbonaceous achondirtes NWA 6704/6693 within the error. The ε54Cr and initial ε53Cr values of Ryugu and NWA 6704/6693 are also identical, while they show distinct Δ'17O values. This suggests that the precursors that formed the progenitor bodies of Ryugu and NWA 6703/6693 were formed in close proximity and experienced a similar degree of thermal processing in the protosolar nebula. However, the progenitor body of Ryugu was formed by a higher ice/dust ratio, than NWA6703/6693, in the outer region of the protoplanetary disk. en-copyright= kn-copyright= en-aut-name=TanakaRyoji

report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Postoperative osimertinib for EGFR mutant non-small cell lung cancer has become the standard of care. However, its adverse events in clinical practice remain unclear. We report a case of interstitial lung disease and pulmonary embolism occurring simultaneously as adverse events during adjuvant osimertinib treatment.
Case presentation A 74-year-old woman, diagnosed with left lower lobe lung adenocarcinoma harboring an EGFR mutation, underwent a left lower lobectomy with lymph node dissection. During adjuvant osimertinib therapy, the patient developed respiratory distress with hypoxia, leading to the diagnosis of interstitial lung disease. Despite immediate steroid therapy, respiratory distress persisted, the patient developed leg edema. She was diagnosed with deep vein thrombosis and pulmonary embolism via contrast-enhanced computed tomography scan. Following treatment with steroid and anticoagulation, her clinical symptoms improved rapidly, and she showed no recurrence of interstitial lung disease, pulmonary embolism, or lung cancer over the following nine months.
Conclusions We encountered a case of interstitial lung disease and pulmonary embolism occurring simultaneously as adverse events during adjuvant osimertinib treatment. In patients with osimertinib-induced interstitial lung disease, particularly when respiratory symptoms show poor improvement with steroid treatment, the possibility of pulmonary embolism complications should be suspected. en-copyright= kn-copyright= en-aut-name=ManabeKenta en-aut-sei=Manabe en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurukawaShinichi en-aut-sei=Furukawa en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SenoTomoya en-aut-sei=Seno en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshimuraKousei en-aut-sei=Ishimura en-aut-mei=Kousei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Thoracic Surgery, Okayama University Hospital kn-affil= en-keyword=Osimertinib kn-keyword=Osimertinib en-keyword=Lung cancer kn-keyword=Lung cancer en-keyword=Interstitial lung disease kn-keyword=Interstitial lung disease en-keyword=Pulmonary embolism kn-keyword=Pulmonary embolism END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=e000923 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250427 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reversible cerebral vasoconstriction syndrome in idiopathic multicentric Castleman disease under treatment with tocilizumab en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Idiopathic multicentric Castleman disease (iMCD) is a rare polyclonal lymphoproliferative disorder characterised by systemic inflammation resulting from overproduction of interleukin 6 (IL-6). While iMCD primarily affects the lymph nodes and related tissues, it can also rarely involve the central nervous system.
Case presentation We report the case of a 58-year-old female patient with at least a 3-year history of iMCD, who experienced acute thunderclap headaches due to reversible cerebral vasoconstriction syndrome (RCVS). RCVS occurred 3 months after initiating treatment with tocilizumab, a humanised anti-IL-6 receptor monoclonal antibody, and was accompanied by focal cortical subarachnoid haemorrhage (SAH). Elevated IL-6 levels were found in both serum and cerebrospinal fluid. MR angiography revealed multiple diffuse stenotic lesions in the bilateral middle and posterior cerebral arteries, which, along with bilateral cerebral oedema, resolved within 3 months. The diffuse nature of the cerebral vasospasm and the presence of bilateral brain oedema suggested that cerebral vasospasm was due to RCVS rather than SAH.
Conclusions In patients with Castleman disease, RCVS may occur due to IL-6-dependent chronic cerebral vascular inflammation, either as a primary condition or as a complication of tocilizumab treatment. en-copyright= kn-copyright= en-aut-name=KamimuraNaoya en-aut-sei=Kamimura en-aut-mei=Naoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UedaNaohisa en-aut-sei=Ueda en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraKatsuo en-aut-sei=Kimura en-aut-mei=Katsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishikoriAsami en-aut-sei=Nishikori en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SatoYasuharu en-aut-sei=Sato en-aut-mei=Yasuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KishidaHitaru en-aut-sei=Kishida en-aut-mei=Hitaru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaFumiaki en-aut-sei=Tanaka en-aut-mei=Fumiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=2 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=3 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= affil-num=6 en-affil=Department of Neurology, Yokohama City University Medical Center kn-affil= affil-num=7 en-affil=Department of Neurology and Stroke Medicine, Yokohama City University Graduate School of Medicine kn-affil= END start-ver=1.4 cd-journal=joma no-vol=22 cd-vols= no-issue=4 article-no= start-page=510 end-page=524 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250626 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=C1orf50 Drives Malignant Melanoma Progression Through the Regulation of Stemness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aim: Recent advancements in omics analysis have significantly enhanced our understanding of the molecular pathology of malignant melanoma, leading to the development of novel therapeutic strategies that target specific vulnerabilities within the disease. Despite these improvements, the factors contributing to the poor prognosis of patients with malignant melanoma remain incompletely understood. The aim of this study was to investigate the role of C1orf50 (Chromosome 1 open reading frame 50), a gene previously of unknown function, as a prognostic biomarker in melanoma.
Materials and Methods: We performed comprehensive transcriptome data analysis and subsequent functional validation of the human Skin Cutaneous Melanoma project from The Cancer Genome Atlas (TCGA).
Results: Elevated expression levels of C1orf50 correlated with worse survival outcomes. Mechanistically, we revealed that C1orf50 plays a significant role in the regulation of cell cycle processes and cancer cell stemness, providing a potential avenue for novel therapeutic interventions in melanoma.
Conclusion: This study is the first to identify C1orf50 as a prognostic biomarker in melanoma. The clinical relevance of our results sheds light on the importance of further investigation into the biological mechanisms underpinning C1orf50’s impact on melanoma progression and patient prognosis. en-copyright= kn-copyright= en-aut-name=OTANIYUSUKE en-aut-sei=OTANI en-aut-mei=YUSUKE kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MAEKAWAMASAKI en-aut-sei=MAEKAWA en-aut-mei=MASAKI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TANAKAATSUSHI en-aut-sei=TANAKA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=PEÑATIRSO en-aut-sei=PEÑA en-aut-mei=TIRSO kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=CHINVANESSA D. en-aut-sei=CHIN en-aut-mei=VANESSA D. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ROGACHEVSKAYAANNA en-aut-sei=ROGACHEVSKAYA en-aut-mei=ANNA kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TOYOOKASHINICHI en-aut-sei=TOYOOKA en-aut-mei=SHINICHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ROEHRLMICHAEL H. en-aut-sei=ROEHRL en-aut-mei=MICHAEL H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FUJIMURAATSUSHI en-aut-sei=FUJIMURA en-aut-mei=ATSUSHI kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=2 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=3 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=4 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=5 en-affil=UMass Chan Medical School, UMass Memorial Medical Center kn-affil= affil-num=6 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center kn-affil= affil-num=9 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=melanoma kn-keyword=melanoma en-keyword=cancer stem cells kn-keyword=cancer stem cells en-keyword=YAP/TAZ kn-keyword=YAP/TAZ END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e86695 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Managing Persistent Pupillary Membranes With Surgery or Medication: A Report of Three Cases en-subtitle= kn-subtitle= en-abstract= kn-abstract=The persistent pupillary membrane, as a congenital anomaly, is a remnant of a network of feeding blood vessels for the lens of the eye, called tunica vasculosa lentis. This study reports three patients with persistent pupillary membrane in both eyes who presented in different situations and were managed differently to achieve better vision. The first child (Case 1) who had been seen initially at the age of two years complained of severe photophobia even though he had good visual acuity, and hence, he and his family chose surgical resection of the pupillary membrane in both eyes at the age of six years just before the admission to an elementary school. He did not develop any surgical complications, such as cataract and glaucoma, and maintained the visual acuity in decimals of 1.2 in both eyes at the age of 17 years.
The second child (Case 2), who was seen first at the age of one month, had persistent pupillary membranes in both eyes, together with Peters' anomaly in the left eye. The iris process adhesion to the corneal inner surface was visualized later by optical coherence tomography. She wore full-correction glasses and obtained the visual acuity of 0.7 in the right eye, so she had no problem studying at an elementary school. She used topical 1% atropine once a week in both eyes to maintain pupillary dilation and also used 0.5% timolol and 1% brinzolamide as pressure-lowering eye drops in the left eye with Peters' anomaly.
The third patient (Case 3) with persistent pupillary membranes in both eyes complained of vision problems for the first time at the age of 49 years when she developed cataract. Surgical resection of the pupillary membrane was done in the initial phase of cataract surgery with intraocular lens implantation in both eyes. At surgical resection of the pupillary membrane, a safe and efficient way was to cut the root of the pupillary membrane on the iris surface with scissors, and then the isolated tissues of the pupillary membrane were pulled out with forceps from the side port at the corneal limbus. Pathological examinations of the excised tissues showed blood vessels with red blood cells in the lumen. In such a rare congenital disease as the persistent pupillary membrane, a case-based approach to choose a better option in different conditions from individual to individual is still required to have a better vision in learning at school and in daily working life. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Division of Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=anterior segment dysgenesis kn-keyword=anterior segment dysgenesis en-keyword=cataract kn-keyword=cataract en-keyword=forceps kn-keyword=forceps en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=persistent pupillary membrane kn-keyword=persistent pupillary membrane en-keyword=peters anomaly kn-keyword=peters anomaly en-keyword=resection kn-keyword=resection en-keyword=scissors kn-keyword=scissors en-keyword=vitrectomy cutter kn-keyword=vitrectomy cutter END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=6 article-no= start-page=e85680 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250610 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Whole-Eye Radiation for the Local Control of Choroidal Lymphoma in Primary Central Nervous System Lymphoma: A 14-Year Case Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Involved-site radiation therapy is effective for curative and palliative treatments of cancers, including lymphoma. This case study describes the use of whole-eye radiation for primary intraocular lymphoma occurring during primary central nervous system lymphoma. The patient, a 68-year-old man, developed personality changes and apathy two weeks after cataract surgery combined with vitrectomy for vitreous opacity in the left eye. Magnetic resonance imaging revealed a mass lesion in the left frontal lobe, and biopsy by craniotomy confirmed diffuse large B-cell lymphoma. He underwent chemotherapy using rituximab combined with high-dose methotrexate and high-dose cytarabine in association with intrathecal methotrexate and cytarabine injections, leading to complete remission. At age 75, he noticed forgetfulness, and fluorodeoxyglucose positron emission tomography and magnetic resonance imaging revealed a relapse of lymphoma in the splenium of the corpus callosum. He underwent chemotherapy using rituximab combined with high-dose methotrexate, followed by monthly rituximab monotherapy for one year and then rituximab monotherapy every two months for one year. He maintained complete remission with no treatment until age 78, when he developed subretinal choroidal lesions in the left eye and underwent whole-eye radiation at 40 Gy. One year later, he developed subretinal choroidal lesions in the right eye and underwent whole-eye radiation at 40 Gy. At age 81, he had lower limb weakness with disorientation. Magnetic resonance imaging showed a relapse of lymphoma in the right frontal to temporal lobe. The brain lesions showed a marked response to four weeks of oral tirabrutinib as a salvage therapy, but the lesions regrew, and the patient died seven months later. Throughout the treatment, he maintained a visual acuity of 0.7 (decimal scale) in both eyes. In conclusion, whole-eye radiation should be considered as a treatment option for the local control of active intraocular lymphoma, especially choroidal lesions, for patients with primary central nervous system lymphoma with no active brain lesions and without systemic treatment. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YanoTomofumi en-aut-sei=Yano en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshioKotaro en-aut-sei=Yoshio en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraHirotake en-aut-sei=Nishimura en-aut-mei=Hirotake kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Hematology and Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=brain biopsy kn-keyword=brain biopsy en-keyword=bruton tyrosine kinase (btk) inhibitor kn-keyword=bruton tyrosine kinase (btk) inhibitor en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=diffuse large b-cell lymphoma kn-keyword=diffuse large b-cell lymphoma en-keyword=fluorodeoxyglucose positron emission tomography kn-keyword=fluorodeoxyglucose positron emission tomography en-keyword=primary central nervous system lymphoma kn-keyword=primary central nervous system lymphoma en-keyword=primary intraocular (vitreoretinal) lymphoma kn-keyword=primary intraocular (vitreoretinal) lymphoma en-keyword=radiation therapy (radiotherapy) kn-keyword=radiation therapy (radiotherapy) en-keyword=tirabrutinib kn-keyword=tirabrutinib en-keyword=whole-eye radiation kn-keyword=whole-eye radiation END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=5 article-no= start-page=164 end-page=173 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Nephronophthisis and Retinitis Pigmentosa (Senior-Loken Syndrome) After Living-Donor Kidney Transplantation: Twelve-Year Follow-Up in a Young Woman en-subtitle= kn-subtitle= en-abstract= kn-abstract=Senior-Loken syndrome is a hereditary ciliopathy with recessive trait that manifests as nephronophthisis and retinitis pigmentosa. This report described an 18-year-old woman who was referred to a University Hospital to set up a treatment plan for chronic renal failure of an unknown cause. She had experienced nocturnal polyurea from the age of 12 years and was found to have an elevated level of serum creatinine at 3 mg/dL at the age of 15 years. She underwent renal biopsy at a hometown regional hospital which showed global glomerulosclerosis in six of the 13 glomeruli examined, renal tubular dilation in irregular shape, and marked interstitial fibrosis with lymphocytic infiltration. At the age of 19 years, she received a living-donor kidney transplant from her 46-year-old father as a preemptive therapy. At surgery, biopsy of the father’s donor kidney showed two glomeruli with global sclerosis out of 24 glomeruli examined, in association with minimal interstitial fibrosis and lymphocytic infiltration. She began to have extended-release tacrolimus 4 mg daily and mycophenolate mofetil 1,000 mg daily. According to the standard protocol, she underwent biopsy of the transplanted donor kidney to reveal interstitial fibrosis and lymphocytic infiltration, in addition to no sign of rejection and no glomerular deposition of immunoglobulins and complements, both 4 weeks and 14 months after the kidney transplantation. At the age of 23 years, 4 years after the kidney transplantation, she was, for the first time, diagnosed retinitis pigmentosa, and hence, Senior-Loken syndrome. She was followed up in the stable condition with basal doses of tacrolimus 5 mg daily, mycophenolate mofetil 1,000 mg daily, and prednisolone 5 mg daily up until now in 12 years after the kidney transplantation. The interstitial fibrosis with lymphocytic infiltration in the donor kidney might be a milder presentation of the disease with recessive inheritance. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiYasuhiro en-aut-sei=Onishi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorinagaHiroshi en-aut-sei=Morinaga en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Urology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Retinitis pigmentosa kn-keyword=Retinitis pigmentosa en-keyword=Nephronophthisis kn-keyword=Nephronophthisis en-keyword=Senior-Loken syndrome kn-keyword=Senior-Loken syndrome en-keyword=Kidney transplantation kn-keyword=Kidney transplantation en-keyword=Living donor kn-keyword=Living donor en-keyword=Kidney biopsy kn-keyword=Kidney biopsy en-keyword=Pathology kn-keyword=Pathology en-keyword=Computed tomography scan kn-keyword=Computed tomography scan en-keyword=Ciliopathy kn-keyword=Ciliopathy en-keyword=Optical coherence tomography kn-keyword=Optical coherence tomography END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=5 article-no= start-page=e83484 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Detailed Ophthalmic and Pathological Features of Choroidal Metastasis From Breast Cancer: A Case Series of Five Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Breast cancer causes choroidal metastases on rare occasions. This study presented the eye manifestations of choroidal metastases from breast cancer and their response to treatments in detail as well as their pathological correlation in five patients. The patients' age at the diagnosis of breast cancer ranged from 24 to 69 years (median: 37 years). The time from the diagnosis of breast cancer to the detection of metastases was concurrent in one patient, two years later in three patients, and six years later in the other patient. The time from the detection of systemic metastases to the detection of choroidal metastases was the same in one patient, while it ranged from one to seven years later in four patients. Choroidal metastases were in the unilateral eye of four patients, whereas they were in both eyes of one patient. Choroidal metastases manifested as one or a few nodular or flat choroidal lesions with serous retinal detachment. As for the treatment of choroidal metastases, enucleation of the right eye was chosen based on the patient's wish as well as the family's wish in the earliest patient when cancer notification was not the norm in Japan. In the other four patients, whole-eye radiation was performed to reduce the choroidal metastatic lesions. As regards the prognosis, which was available in four patients, three patients died within one year from the diagnosis of choroidal metastases, while one patient died one year and eight months later. Regarding the pathology of breast cancer, which was available in four patients, immunostaining of the preserved enucleated eye in the earliest patient revealed that breast cancer cells in the choroidal metastatic lesion were positive for estrogen receptor and negative for progesterone receptor and human epidermal growth factor receptor 2 (HER2). Invasive ductal carcinoma in two patients was positive for estrogen receptor and negative for HER2, while invasive ductal carcinoma in the other patient was triple-negative for estrogen receptor, progesterone receptor, and HER2 with a high Ki-67 index. In conclusion, the prognosis for life was poor in patients with breast cancer who developed choroidal metastases. Choroidal metastatic lesions showed a response to whole-eye radiation to improve the quality of vision at the end of life. Vision-related symptoms should be monitored in the course of chemotherapy for systemic metastases. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuraokaAtsushi en-aut-sei=Muraoka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Division of Healthcare Science, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=choroidal metastasis kn-keyword=choroidal metastasis en-keyword=estrogen receptor kn-keyword=estrogen receptor en-keyword=her2 kn-keyword=her2 en-keyword=immunostaining kn-keyword=immunostaining en-keyword=invasive ductal carcinoma kn-keyword=invasive ductal carcinoma en-keyword=ki-67 kn-keyword=ki-67 en-keyword=progesterone receptor kn-keyword=progesterone receptor en-keyword=radiation kn-keyword=radiation END start-ver=1.4 cd-journal=joma no-vol=31 cd-vols= no-issue=6 article-no= start-page=388.e1 end-page=388.e14 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical effects of granulocyte colony-stimulating factor administration and the timing of its initiation on allogeneic hematopoietic cell transplantation outcomes for myelodysplastic syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Granulocyte colony-stimulating factor (G-CSF) accelerates neutrophil recovery after allogeneic hematopoietic cell transplantation (HCT). However, the optimal use of G-CSF and the timing of its initiation after allogeneic HCT for myelodysplastic syndrome (MDS) according to graft type have not been determined. This retrospective study aimed to investigate the effects of using G-CSF administration and the timing of its initiation on transplant outcomes in adult patients with MDS undergoing allogeneic HCT. Using Japanese registry data, we retrospectively investigated the effects of G-CSF administration and the timing of its initiation on transplant outcomes among 4140 adults with MDS after bone marrow transplantation (BMT), peripheral blood stem cell transplantation (PBSCT), or single-unit cord blood transplantation (CBT) between 2013 and 2022. Multivariate analysis showed that early (days 0 to 4) and late (days 5 to 10) G-CSF administration significantly accelerated neutrophil recovery compared with no G-CSF administration following BMT, PBSCT, and CBT, but there was no benefit of early G-CSF initiation for early neutrophilic recovery regardless of graft type. Late G-CSF initiation was significantly associated with a higher risk of overall chronic GVHD following PBSCT (hazard ratio [HR], 1.63; 95% confidence interval [CI], 1.18 to 2.24; P = .002) and CBT (HR, 2.09; 95% CI, 1.21 to 3.60; P = .007) compared with no G-CSF administration. Late G-CSF initiation significantly improved OS compared with no G-CSF administration only following PBSCT (HR, 0.74; 95% CI, 0.58 to 0.94; P = .015). However, G-CSF administration and the timing of its initiation did not affect acute GVHD, relapse, or non-relapse mortality, irrespective of graft type. These results suggest that G-CSF administration significantly accelerated neutrophil recovery after BMT, PBSCT, and CBT, but increased risk of overall chronic GVHD after PBSCT and CBT. However, the effect of early and late G-CSF initiation on transplant outcomes needs further study in adult patients with MDS. en-copyright= kn-copyright= en-aut-name=KonumaTakaaki en-aut-sei=Konuma

scattering functions in contrast variation small-angle neutron scattering via Gaussian process regression with prior knowledge of smoothness en-subtitle= kn-subtitle= en-abstract= kn-abstract=Contrast variation small-angle neutron scattering (CV-SANS) is a powerful tool for evaluating the structure of multi-component systems. In CV-SANS, the scattering intensities I(Q) measured with different scattering contrasts are decomposed into partial scattering functions S(Q) of the self- and cross-correlations between components. Since the measurement has a measurement error, S(Q) must be estimated statistically from I(Q). If no prior knowledge about S(Q) is available, the least-squares method is best, and this is the most popular estimation method. However, if prior knowledge is available, the estimation can be improved using Bayesian inference in a statistically authorized way. In this paper, we propose a novel method to improve the estimation of S(Q), based on Gaussian process regression using prior knowledge about the smoothness and flatness of S(Q). We demonstrate the method using synthetic core–shell and experimental polyrotaxane SANS data. en-copyright= kn-copyright= en-aut-name=ObayashiIppei en-aut-sei=Obayashi en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyajimaShinya en-aut-sei=Miyajima en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKazuaki en-aut-sei=Tanaka en-aut-mei=Kazuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MayumiKoichi en-aut-sei=Mayumi en-aut-mei=Koichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Center for Artificial Intelligence and Mathematical Data Science, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Science and Engineering, Iwate University kn-affil= affil-num=3 en-affil=Global Center for Science and Engineering, Waseda University kn-affil= affil-num=4 en-affil=Institute for Solid State Physics, University of Tokyo kn-affil= en-keyword=contrast variation small-angle neutron scattering kn-keyword=contrast variation small-angle neutron scattering en-keyword=CV-SANS kn-keyword=CV-SANS en-keyword=partial scattering functions kn-keyword=partial scattering functions en-keyword=multi-component systems kn-keyword=multi-component systems en-keyword=statistical methods kn-keyword=statistical methods en-keyword=Bayesian inference kn-keyword=Bayesian inference en-keyword=contrast variation kn-keyword=contrast variation en-keyword=Gaussian process regression kn-keyword=Gaussian process regression END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=ラドン吸入がマウス脳中のタンパク質に及ぼす作用：プロテオーム解析と多変量解析を用いた検討 kn-title=Effect of Radon Inhalation on Murine Brain Proteins : Investigation Using Proteomic and Multivariate Analyses en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=NAOEShota en-aut-sei=NAOE en-aut-mei=Shota kn-aut-name=直江翔太 kn-aut-sei=直江 kn-aut-mei=翔太 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil=岡山大学大学院保健学研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=持続的な甘味刺激が唾液流量に及ぼす影響 kn-title=Effect of continuous sweet gustatory stimulation on salivary flow rate over time en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=YAMADARanko en-aut-sei=YAMADA en-aut-mei=Ranko kn-aut-name=山田蘭子 kn-aut-sei=山田 kn-aut-mei=蘭子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250325 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=小児骨形成不全症患者におけるTrabecular bone scoreのビスホスホネート治療に対する反応は重症度によって異なる kn-title=Trabecular bone scores in children with osteogenesis imperfecta respond differently to bisphosphonate treatment depending on disease severity en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FUTAGAWANatsuko en-aut-sei=FUTAGAWA en-aut-mei=Natsuko kn-aut-name=二川奈都子 kn-aut-sei=二川 kn-aut-mei=奈都子 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=7 cd-vols= no-issue=1 article-no= start-page=vdaf036 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Evaluating short-term survivors of glioblastoma: A proposal based on SEER registry data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Glioblastomas (GBMs) are central nervous system tumors with a poor prognosis and limited treatment options. Although small subsets of GBM patients survive longer than 3 years, there is little evidence regarding the prognostic factors of GBM. Therefore, we conducted a thorough characterization of GBM in the United States.
Methods: We queried the Surveillance, Epidemiology, and End Results database between 2000 and 2021 to extract age-adjusted incidence rates (AAIRs), age-adjusted mortality rates (AAMRs), and survival data for GBM. We compared trends in AAIR, AAMR, and survival time across age groups 0–14, 15–39, 40–69, and 70+ years. Also, we employed the Fine–Gray competing risk model among short-term survivors (STSs), defined as those with a survival time of 6 months or less, and long-term survivors (LTSs), defined as those with a survival time of 3 years or more.
Results: This study included 60 615 incident GBM cases, 54 998 GBM-specific deaths, and 47 207 GBM patients with available survival time between 2000 and 2021. The mortality-to-incidence ratio was constant among STSs, whereas it increased with age among LTSs. Higher age and male sex were significantly associated with GBM-specific death among LTSs, whereas non-Hispanic White and less intensive treatments were associated with GBM-specific deaths among STSs. Interestingly, higher age was significantly associated with other causes of death among STSs.
Conclusions: STSs partially consist of populations who died from causes other than GBM. It is important to include only GBM-specific deaths in STS groups to conduct reproducible research comparing STSs and LTSs. en-copyright= kn-copyright= en-aut-name=TomitaYusuke en-aut-sei=Tomita en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OmaeRyo en-aut-sei=Omae en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizutaRyo en-aut-sei=Mizuta en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirotsuneNobuyuki en-aut-sei=Hirotsune en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurosurgery and Neuroendovascular Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=glioblastoma kn-keyword=glioblastoma en-keyword=long-term survivor kn-keyword=long-term survivor en-keyword=SEER kn-keyword=SEER en-keyword=short-term survivor kn-keyword=short-term survivor en-keyword=United States kn-keyword=United States END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=209 end-page=212 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Aniline Poisoning Manifesting as Cyanosis with Unknown Cause en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 38-year-old man was brought to the hospital for emergency treatment of cyanosis. The patient exhibited generalized cyanosis and impaired consciousness despite adequate oxygen therapy. Arterial blood was black, and arterial blood gas analysis revealed an abnormally high methemoglobin level of 67.8%. We later interviewed his colleagues regarding his exposure to aniline while working at the factory and diagnosed him with methemoglobinemia due to aniline poisoning. The patient was administered methylene blue (MB) after being transferred to another hospital, where this treatment was available, resulting in an improvement in symptoms. Although rare, methemoglobinemia is serious. A good understanding of the circumstances at disease onset, characteristic findings, and abnormal values of methemoglobinemia is important. In addition, MB is an important therapeutic for the treatment of methemoglobinemia; if MB is not available at a particular hospital, transfer of the patient to a hospital that stocks MB should be considered. en-copyright= kn-copyright= en-aut-name=TaguchiKenichi en-aut-sei=Taguchi en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiKazuya en-aut-sei=Nishii en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HataSakura en-aut-sei=Hata en-aut-mei=Sakura kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuyamaShoichi en-aut-sei=Kuyama en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaShoichi en-aut-sei=Tanaka en-aut-mei=Shoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology, NHO Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, NHO Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Gastroenterology, NHO Iwakuni Clinical Center kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil=Department of Gastroenterology, NHO Iwakuni Clinical Center kn-affil= en-keyword=methemoglobinemia kn-keyword=methemoglobinemia en-keyword=aniline kn-keyword=aniline en-keyword=methylene blue kn-keyword=methylene blue en-keyword=cyanosis kn-keyword=cyanosis END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=3 article-no= start-page=167 end-page=176 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202506 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Promising Effectiveness of Combined Chemotherapy and Immunotherapy in Patients with Advanced Non-small Cell Lung Cancer: A Real-World Prospective Observational Study (CS-Lung-003) en-subtitle= kn-subtitle= en-abstract= kn-abstract=This prospective observational study investigated the clinical status of patients with advanced non-small cell lung cancer (NSCLC) treated with cytotoxic chemotherapy+an immune checkpoint inhibitor (chemo + IO) as first-line treatment in a real-world setting. The cases of 98 patients treated with chemo + IO were prospectively collected and analyzed for effectiveness and safety. The response rate to chemo + IO was 46.9%, and the disease control rate was 76.5%. The median progression-free survival and overall survival (OS) in the total population were 5.2 and 22.3 months, respectively. The patients positive for PD-L1 (≥ 1%) showed significantly longer OS than the negative group (<1%) (median 26.7 vs. 18.7 months, p=0.04). Pre-existing interstitial lung disease (ILD) was associated with shorter OS than the absence of ILD (median 9.0 vs. 22.6 months, p<0.01). Immunerelated adverse events (irAEs) were observed in 28 patients (28.6%). The most frequent irAE was ILD (n=11); Grade 1 (n=1 patient), G2 (n=5), G3 (n=4), and only a single patient with a G5 irAE. In this CS-Lung-003 study, first-line chemo + IO in a real-world setting showed good effectiveness, comparable to that observed in international clinical trials. In real-world practice, chemo + IO is a promising and steadfast strategy. en-copyright= kn-copyright= en-aut-name=KanajiNobuhiro en-aut-sei=Kanaji en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiKazuya en-aut-sei=Nishii en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsubataYukari en-aut-sei=Tsubata en-aut-mei=Yukari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaoMika en-aut-sei=Nakao en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkunoTakae en-aut-sei=Okuno en-aut-mei=Takae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkawaSachi en-aut-sei=Okawa en-aut-mei=Sachi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakataKenji en-aut-sei=Takata en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KodaniMasahiro en-aut-sei=Kodani en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamasakiMasahiro en-aut-sei=Yamasaki en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujitakaKazunori en-aut-sei=Fujitaka en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KubotaTetsuya en-aut-sei=Kubota en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=InoueMasaaki en-aut-sei=Inoue en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=WatanabeNaoki en-aut-sei=Watanabe en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=HottaKatsuyuki en-aut-sei=Hotta en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=CS-Lung-003 Investigator en-aut-sei=CS-Lung-003 Investigator en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Internal Medicine, Division of Hematology, Rheumatology and Respiratory Medicine, Faculty of Medicine, Kagawa University kn-affil= affil-num=2 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Division of Medical Oncology and Respiratory Medicine, Shimane University Faculty of Medicine kn-affil= affil-num=6 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Medical Oncology and Molecular Respirology, Faculty of Medicine, Tottori University kn-affil= affil-num=9 en-affil=Department of Respiratory Disease, Hiroshima Red Cross Hospital and Atomic-Bomb Survivors Hospital kn-affil= affil-num=10 en-affil=Department of Molecular and Internal Medicine, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine and Allergology, Kochi University kn-affil= affil-num=12 en-affil=Department of Chest Surgery, Shimonoseki City Hospital kn-affil= affil-num=13 en-affil=Department of Internal Medicine, Division of Hematology, Rheumatology and Respiratory Medicine, Faculty of Medicine, Kagawa University kn-affil= affil-num=14 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil= kn-affil= en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=real-world kn-keyword=real-world en-keyword=first-line kn-keyword=first-line en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=combined immunotherapy kn-keyword=combined immunotherapy END start-ver=1.4 cd-journal=joma no-vol=64 cd-vols= no-issue=3 article-no= start-page=343 end-page=350 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Characteristics of Early Gastric Cancer in a Patient with a History of Helicobacter pylori Infection and No History of Eradication Therapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective The characteristics of gastric cancer in patients with atrophic mucosa and no apparent history of Helicobacter pylori eradication have not been thoroughly investigated. Therefore, this study examined the clinicopathological characteristics of gastric cancer in these patients.
Methods We retrospectively examined the endoscopic and pathological characteristics of gastric cancer in patients who underwent endoscopic submucosal dissection.
Patients We divided the patients into 2 groups: those with gastric atrophy and no history of eradication (group A; n=102) and those with a history of eradication (group B; n=161). In group A, patients were further divided into mild atrophy (group C) and severe atrophy (group D) groups, while group B was further divided into those who underwent eradication treatment >5 years ago (group E) and those who underwent eradication 1-5 years ago (group F).
Results Group A comprised significantly older individuals (75±8.0 vs. 71±7.5 years old, p<0.001) with a higher frequency of elevated gastric cancer than group B (32.4% vs. 17.4%, p=0.006). Compared with group E, group A was older and had a greater incidence of elevated gastric cancer. The incidence of gastric cancer in the U or M region was lower in group C than in group D.
Conclusion Gastric cancer in patients with gastric atrophy and no history of eradication was associated with an older age and higher frequency of elevated-type morphology than in those with a history of eradication. en-copyright= kn-copyright= en-aut-name=KuraokaSakiko en-aut-sei=Kuraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=InoShoko en-aut-sei=Ino en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatomiTakuya en-aut-sei=Satomi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=autoimmune gastritis kn-keyword=autoimmune gastritis en-keyword=eradication kn-keyword=eradication en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=Helicobacter pylori kn-keyword=Helicobacter pylori END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=4 article-no= start-page=e70151 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Frequency and Characteristics of Gastrointestinal Diseases in Patients With Neurofibromatosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aim: Patients with neurofibromatosis (NF) frequently experience gastrointestinal symptoms, but the specific characteristics of these lesions are not well understood.
Methods: To investigate the prevalence and nature of gastrointestinal diseases in this population, we analyzed the gastrointestinal lesions identified through endoscopic examinations in patients with NF.
Results: We included 225 patients with NF type 1 (NF1) and 15 with NF type 2 (NF2). None of the NF2 patients underwent endoscopy. Among the NF1 patients, 27 received endoscopies, and 13 (59%) had gastrointestinal lesions. These 13 patients were predominantly male (10 males and three females), with a median age of 53 years (range: 19-76 years). The identified lesions included colorectal polyps (n = 6), gastrointestinal stromal tumors ([GIST], n = 4), subepithelial lesions (n = 3), gastric fundic gland polyps (n = 3), diffuse intestinal ganglioneuromatosis (n = 2), esophageal polyps (n = 2), a Schwann cell hamartoma (n = 1), esophageal cancer (n = 1), and a gastric hyperplastic polyp (n = 1). All GISTs and one case of diffuse intestinal ganglioneuromatosis were surgically resected. Interestingly, six out of 13 patients were asymptomatic. Additionally, all patients who required surgery were 40 years of age or older.
Conclusions: These findings suggest that routine endoscopic examinations, along with imaging techniques like computed tomography and magnetic resonance imaging, could be beneficial for the early detection of gastrointestinal lesions in NF1 patients aged 40 and above. en-copyright= kn-copyright= en-aut-name=HondaManami en-aut-sei=Honda en-aut-mei=Manami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Practical Gastrointestinal Endoscopy,Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=colonoscopy kn-keyword=colonoscopy en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=gastrointestinal neoplasms kn-keyword=gastrointestinal neoplasms en-keyword=gastrointestinal stromal tumor kn-keyword=gastrointestinal stromal tumor en-keyword=neurofibromatosis kn-keyword=neurofibromatosis END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=139 end-page=144 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Safe Resection of Esophageal Cancer with a Non-Recurrent Inferior Laryngeal Nerve Associated with an Aberrant Right Subclavian Artery Using Intraoperative Nerve Monitoring en-subtitle= kn-subtitle= en-abstract= kn-abstract=In thoracic esophageal cancer, lymph node dissection around the recurrent laryngeal nerve is crucial but poses a risk of nerve palsy, affecting postoperative quality of life. In cases with an aberrant right subclavian artery (ARSA), the right recurrent laryngeal nerve is absent, and the non-recurrent inferior laryngeal nerve (NRILN) enters the larynx directly from the vagus nerve in the cervical region. Identifying the course of the NRILN is vital to avoid injury. A case of esophageal cancer with an ARSA, in which the course of the NRILN was preserved using the Nerve Integrity Monitoring (NIM) system during surgery, is described. en-copyright= kn-copyright= en-aut-name=TakedaYasushige en-aut-sei=Takeda en-aut-mei=Yasushige kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NomaKazuhiro en-aut-sei=Noma en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaNaoaki en-aut-sei=Maeda en-aut-mei=Naoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizusawaYohei en-aut-sei=Mizusawa en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoHijiri en-aut-sei=Matsumoto en-aut-mei=Hijiri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KondoYuhei en-aut-sei=Kondo en-aut-mei=Yuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KunitomoTomoyoshi en-aut-sei=Kunitomo en-aut-mei=Tomoyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanoueYukinori en-aut-sei=Tanoue en-aut-mei=Yukinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HashimotoMasashi en-aut-sei=Hashimoto en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanabeShunsuke en-aut-sei=Tanabe en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterological Surgery, Okayama University Hospital kn-affil= en-keyword=esophageal cancer kn-keyword=esophageal cancer en-keyword=intraoperative nerve monitoring kn-keyword=intraoperative nerve monitoring en-keyword=aberrant right subclavian artery kn-keyword=aberrant right subclavian artery en-keyword=non-recurrent inferior laryngeal nerve kn-keyword=non-recurrent inferior laryngeal nerve en-keyword=thoracoscopic esophagectomy kn-keyword=thoracoscopic esophagectomy END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=135 end-page=138 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Calcified Amorphous Tumor of the Left Ventricle with Paroxysmal Atrial Fibrillation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cardiac calcified amorphous tumor (CAT) is a rare, benign non-neoplastic mass of the heart that is sometimes found due to embolic events.

Here we report a case of left ventricular CAT complicated by paroxysmal atrial fibrillation (PAF) that was successfully treated with surgical removal and pulmonary vein isolation. Pulmonary vein isolation can be a simple and effective procedure for PAF, even during surgical removal of CAT. en-copyright= kn-copyright= en-aut-name=FujitaYasufumi en-aut-sei=Fujita en-aut-mei=Yasufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShimizuShuji en-aut-sei=Shimizu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MohriMakoto en-aut-sei=Mohri en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Kure Kyosai Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= en-keyword=calcified amorphous tumor kn-keyword=calcified amorphous tumor en-keyword=surgical removal kn-keyword=surgical removal en-keyword=embolic stroke kn-keyword=embolic stroke en-keyword=paroxysmal atrial fibrillation kn-keyword=paroxysmal atrial fibrillation en-keyword=pulmonary vein isolation kn-keyword=pulmonary vein isolation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=81 end-page=92 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Outcomes of Neoadjuvant Paclitaxel/Cisplatin/Gemcitabine Compared with Gemcitabine/Cisplatin for Muscle-Invasive Bladder Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=We retrospectively evaluated the oncologic outcomes of paclitaxel, cisplatin, and gemcitabine (PCG) with those of gemcitabine and cisplatin (GC) as neoadjuvant chemotherapy in muscle-invasive bladder cancer (MIBC) patients. The primary outcome was efficacy: pathological complete response (pCR), ypT0N0; and pathological objective response (pOR), ypT0N0, ≤ ypT1N0, or ypT0N1. Secondary outcomes included overall survival (OS), recurrence-free survival (RFS), predictive factors for pOR, OS, and RFS, and hematologic adverse events (AEs). Among 113 patients treated (PCG, n=28; GC, n=85), similar pOR and pCR rates were achieved by the groups (pOR: PCG, 57.1% vs. GC, 49. 4%; p=0.52; pCR: PCG, 39.3% vs. GC, 29.4%; p=0.36). No significant differences were observed in OS (p=1.0) or RFS (p=0.20). Multivariate logistic regression analysis showed that hydronephrosis (odds ratio [OR] 0.32, 95%CI: 0.11-0.92) and clinical node-positive status (cN+) (OR 0.22, 95%CI: 0.050-0.99) were significantly associated with a decreased probability of pOR. On multivariate Cox regression analyses, pOR achievement was associated with improved OS (hazard ratio [HR] 0.23, 95%CI: 0.10-0.56) and RFS (HR 0.30, 95%CI: 0.13-0.67). There were no significant between-group differences in the incidence of grade ≥ 3 hematologic AEs or dose-reduction required, but the PCG group had a higher incidence of grade 4 neutropenia. en-copyright= kn-copyright= en-aut-name=KawadaTatsushi en-aut-sei=Kawada en-aut-mei=Tatsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsugawaTakuji en-aut-sei=Tsugawa en-aut-mei=Takuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsuboiKazuma en-aut-sei=Tsuboi en-aut-mei=Kazuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwataTakehiro en-aut-sei=Iwata en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KobayashiTomoko en-aut-sei=Kobayashi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=EdamuraKohei en-aut-sei=Edamura en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EbaraShin en-aut-sei=Ebara en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Urology, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=11 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=urothelial carcinoma kn-keyword=urothelial carcinoma en-keyword=paclitaxel kn-keyword=paclitaxel en-keyword=cisplatin kn-keyword=cisplatin en-keyword=gemcitabine kn-keyword=gemcitabine en-keyword=neoadjuvant kn-keyword=neoadjuvant END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=2 article-no= start-page=65 end-page=73 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202504 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between the Pretreatment Body Mass Index and Anamorelin’s Efficacy in Patients with Cancer Cachexia: A Retrospective Cohort Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Anamorelin (ANAM) is used to treat cancer-associated cachexia, a syndrome involving muscle loss and anorexia.

Although the body mass index (BMI) is a diagnostic criterion for cancer cachexia, no studies have explored its association with ANAM efficacy. We conducted a single-center, retrospective cohort study to investigate the association between the pre-treatment BMI and ANAM efficacy in patients with cancer-associated cachexia (n=47). The ANAM treatment was considered effective if the patient’s appetite improved within 30 days of treatment initiation. We calculated a BMI cutoff value (19.5 kg/m2) and used it to divide the patients into high- and low-BMI groups. Their background, clinical laboratory values, cancer types, and treatment lines were investigated. Twenty (42.6%) had a high BMI (≥ 19.5 kg/m2) and 27 (57.4%) had a low BMI (< 19.5 kg/m2). High BMI was significantly associated with ANAM effectiveness (odds ratio 7.86, 95% confidence interval 1.99-31.00, p=0.003). Together these results indicate that it is beneficial to initiate ANAM treatment before a patient’s BMI drops below 19.5 kg/m2. Our findings will help advance cancer cachexia treatment and serve as a reference for clinicians to predict ANAM’s efficacy. en-copyright= kn-copyright= en-aut-name=MakiMasatoshi en-aut-sei=Maki en-aut-mei=Masatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakadaRyo en-aut-sei=Takada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshigoTomoyuki en-aut-sei=Ishigo en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraMiki en-aut-sei=Fujiwara en-aut-mei=Miki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakahashiYoko en-aut-sei=Takahashi en-aut-mei=Yoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TamuraKoji en-aut-sei=Tamura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HamaokaTerutaka en-aut-sei=Hamaoka en-aut-mei=Terutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=2 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Pharmacy, Sapporo Medical University Hospital kn-affil= affil-num=4 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=5 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=6 en-affil=Department of Surgery, NHO Fukuyama Medical Center kn-affil= affil-num=7 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= affil-num=8 en-affil=Department of Hospital Pharmacy, NHO Fukuyama Medical Center kn-affil= en-keyword=anamorelin kn-keyword=anamorelin en-keyword=cancer-associated cachexia kn-keyword=cancer-associated cachexia en-keyword=body mass index kn-keyword=body mass index en-keyword=albumin kn-keyword=albumin en-keyword=efficacy rate kn-keyword=efficacy rate END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=4 article-no= start-page=e82348 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250416 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bilateral Scleritis and Neutrophilic Dermatosis With Cytogenetic Chromosomal Aberrancy Related to Pyoderma Gangrenosum: A Case Report of a 20-Year Follow-Up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pyoderma gangrenosum is a non-infectious autoimmune disease with skin plaques and ulcers in the entity of neutrophilic dermatosis and may have a background of myelodysplastic syndromes. This study reported a 20-year follow-up of a patient with pyoderma gangrenosum and scleritis who showed chromosomal aberrancy from the initial phase and later in the course developed thrombocythemia. A 51-year-old man presented with widespread indurated erythematous plaques with scaling and pustules on the forehead, bilateral eyelids, and nasal bridge, in addition to nodular scleritis in the left eye and ulcer formation of the plaques in the lower legs. Skin biopsy revealed massive dermal infiltration mainly with neutrophils in the absence of neutrophilic vasculitis. Suspected of myelodysplastic syndromes, bone marrow biopsy was normal, while chromosomal aberrancy, 46, XY, del (20) (q11q13.3), was detected. In the diagnosis of neutrophilic dermatosis, probably of pyoderma gangrenosum, he began to have oral prednisolone 20 mg daily and colchicine 1 mg daily, leading to the subsidence of skin lesions. Four months later, he developed nodular scleritis in the right eye and began to use topical 0.1% betamethasone in both eyes. He was stable with only prednisolone 12.5 mg daily until the age of 55.5 years, when he showed an increase of serum lactate dehydrogenase. The bone marrow aspirate disclosed neither blast cell increase nor atypical cells. The same chromosomal aberrancy was repeatedly detected. One year later, he developed breathing difficulty and underwent tracheostomy. Laryngeal lesion biopsy disclosed squamous cell papilloma with human papillomavirus-6. At 60 years old, he showed marginal corneal infiltration in the left eye, and at 61 years old, hypopyon in the right eye. Platelets tended to increase up to 1000 × 103/µL, and bone marrow examinations were recommended but refused by the patient. At the latest follow-up at 71 years old, he was ambulatory in health and stable with a tracheostomy cannula. In conclusion, pyoderma gangrenosum with scleritis occurred in an undetermined hematological malignancy with chromosomal aberrancy. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AsadaNoboru en-aut-sei=Asada en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ObikaMikako en-aut-sei=Obika en-aut-mei=Mikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OmichiRyotaro en-aut-sei=Omichi en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwatsukiKeiji en-aut-sei=Iwatsuki en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Internal Medicine, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Otolaryngology, Head and Neck Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=corneal infiltration kn-keyword=corneal infiltration en-keyword=hypopyon kn-keyword=hypopyon en-keyword=myelodysplastic syndromes kn-keyword=myelodysplastic syndromes en-keyword=neutrophilic dermatosis kn-keyword=neutrophilic dermatosis en-keyword=peripheral keratitis kn-keyword=peripheral keratitis en-keyword=pyoderma gangrenosum kn-keyword=pyoderma gangrenosum en-keyword=scleritis kn-keyword=scleritis en-keyword=sweet syndrome kn-keyword=sweet syndrome END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=1 article-no= start-page=141 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Primary chest wall sarcoma: advances in surgical management and outcomes en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Although rare, primary chest wall sarcomas are complex malignancies necessitating optimal local control and comprehensive treatment. This study aimed to review 9 years of cases of primary chest wall sarcomas at a single institution, focusing on their histology, surgical management, and prognosis.
Methods A retrospective analysis was performed on 19 patients undergoing chest wall resection for sarcoma from 2012 to 2020. Data on demographics, tumor specifics, resection extent, and adjuvant therapies were collected. Surgical and postoperative outcomes were also assessed.
Results The median patient age was 64 years. Chondrosarcoma was the most common histology. R0 resection was achieved in all patients, with early postoperative complications occurring in 11% of the patients. Robust chest wall reconstruction was performed, resulting in minimal respiratory complications. The 5-year overall survival and disease-free survival rates were 94% and 68%, respectively. Tumor size and patient age were significant prognostic factors for local recurrence.
Conclusion Comprehensive surgical resection, coupled with multidisciplinary preoperative planning, achieves favorable outcomes. Patients aged ≥ 70 years and with tumor size ≥ 5 cm (P = .047) should be carefully followed up for local recurrence. en-copyright= kn-copyright= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItanoTakuto en-aut-sei=Itano en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TomiokaYasuaki en-aut-sei=Tomioka en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Primary chest wall sarcomas kn-keyword=Primary chest wall sarcomas en-keyword=Chest wall resection kn-keyword=Chest wall resection en-keyword=Chondrosarcoma kn-keyword=Chondrosarcoma en-keyword=Robust chest wall reconstruction kn-keyword=Robust chest wall reconstruction END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=3 article-no= start-page=e81476 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Natural Course From Primary Intraocular Lymphoma to Brain Lymphoma in Four Years According to Patient's Choice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary intraocular lymphoma or vitreoretinal lymphoma is a rare entity of diffuse large B-cell lymphoma that presents vitreous opacity and retinal and choroidal infiltration. Primary central nervous system lymphoma would occur previously, later, or concurrently with respect to primary intraocular lymphoma. This study reported a 72-year-old patient with a pathological diagnosis of primary intraocular lymphoma who developed central nervous system lymphoma four years later in the course of no treatment. She presented with a four-year history of blurred vision in both eyes after cataract surgeries. Three weeks previously, she underwent a vitrectomy in the left eye at a clinic, and measurements of the vitreous fluid showed a high level of interleukin-10 at 5739 pg/mL, in contrast with interleukin-6 at 142 pg/mL. Cytology of the vitreous fluid was class III on the Papanicolaou classification. Head magnetic resonance imaging detected nothing abnormal. She underwent vitrectomy in the right eye as a diagnostic procedure to show large cells in the vitreous which were positive for CD20 and Ki-67 and negative for CD3, leading to a pathological diagnosis of large B-cell lymphoma. Prophylactic chemotherapy with high-dose methotrexate was recommended as a therapeutic option, but she chose observation since she did not have any eye or systemic symptoms. In the follow-up every three months by an oncologist and an ophthalmologist, she did not have any symptoms, and serum levels of soluble interleukin-2 receptor were in the normal range at each visit. She was well for four years until the age of 76 years when she fell and hit her head, and an emergency head computed tomography scan showed a mass in the left occipital lobe. Magnetic resonance imaging demonstrated a well-defined circular mass in the left occipital lobe with a hyperintense signal in the T2-weighted fluid-attenuated inversion recovery (FLAIR) image and diffusion-weighted image. Fluorodeoxyglucose positron emission tomography showed no abnormal uptake systemically, except for the left occipital lesion. She underwent a brain biopsy by craniotomy to pathologically prove diffuse large B-cell lymphoma. She was recommended to receive first-line chemotherapy as the standard treatment but chose observation with no treatment and died of brain lymphoma nine months later. This case happened to illustrate a natural course of primary intraocular lymphoma which proceeded to central nervous system lymphoma four years later. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoShotaro en-aut-sei=Kondo en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Kurashiki Municipal Hospital kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=brain biopsy kn-keyword=brain biopsy en-keyword=cell block pathology kn-keyword=cell block pathology en-keyword=diffuse large b-cell lymphoma kn-keyword=diffuse large b-cell lymphoma en-keyword=natural course kn-keyword=natural course en-keyword=primary central nervous system lymphoma kn-keyword=primary central nervous system lymphoma en-keyword=primary intraocular (vitreoretinal) lymphoma kn-keyword=primary intraocular (vitreoretinal) lymphoma en-keyword=vitrectomy kn-keyword=vitrectomy en-keyword=vitreous opacity kn-keyword=vitreous opacity END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=6 article-no= start-page=1082 end-page=1096 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Myeloid Cells Induce Infiltration and Activation of B Cells and CD4+ T Follicular Helper Cells to Sensitize Brain Metastases to Combination Immunotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Brain metastasis is a poor prognostic factor in patients with cancer. Despite showing efficacy in many extracranial tumors, immunotherapy with anti–PD-1 mAb or anti–CTLA4 mAb seems to be less effective against intracranial tumors. Promisingly, recent clinical studies have reported that combination therapy with anti–PD-1 and anti–CTLA4 mAbs has a potent antitumor effect on brain metastasis, highlighting the need to elucidate the detailed mechanisms controlling the intracranial tumor microenvironment (TME) to develop effective immunotherapeutic strategies. In this study, we analyzed the tumor-infiltrating lymphocytes in murine models of brain metastasis that responded to anti–CTLA4 and anti–PD-1 mAbs. Activated CD4+ T follicular helper (TFH) cells with high CTLA4 expression characteristically infiltrated the intracranial TME, which were activated by combination anti–CTLA4 and anti–PD-1 treatment. The loss of TFH cells suppressed the additive effect of CTLA4 blockade on anti–PD-1 mAb. B-cell–activating factor belonging to the TNF family (BAFF) and a proliferation-inducing ligand (APRIL) produced by abundant myeloid cells, particularly CD80hiCD206lo proinflammatory M1-like macrophages, in the intracranial TME induced B-cell and TFH-cell infiltration and activation. Furthermore, the intracranial TME of patients with non–small cell lung cancer featured TFH- and B-cell infiltration as tertiary lymphoid structures. Together, these findings provide insights into the immune cell cross-talk in the intracranial TME that facilitates an additive antitumor effect of CTLA4 blockade with anti–PD-1 treatment, supporting the potential of a combination immunotherapeutic strategy for brain metastases.
Significance: B-cell and CD4+ T follicular helper cell activation via BAFF/APRIL from abundant myeloid cells in the intracranial tumor microenvironment enables a combinatorial effect of CTLA4 and PD-1 blockade in brain metastases. en-copyright= kn-copyright= en-aut-name=NinomiyaToshifumi en-aut-sei=Ninomiya en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

learn independently, they need learning experiences that extend beyond the classroom, including at home. In other words, learning is not confined to the classroom but is reinforced through a wide range of activities. This study aimed to nurture “autonomous and self-directed learning” among students in the second grade at a public junior high school by integrating classroom and home learning. Teachers emphasized the importance of learning strategies and goal setting, and encouraged metacognition. As a result, students became more aware of the self-regulated learning cycle and began exploring learning strategies tailored to their needs. In addition, working at home on assignments connected to the class not only increased students’ active participation in class but also improved their motivation to learn independ ently outside of class. kn-abstract=　生徒が自ら学習を進めていく力を身に付けるには，授業内だけでなく，家庭など授業外の場での学習経験を積む必要がある。つまり，学習は授業内だけで完結するのではなく，広範な活動を通して成立する。本研究では，公立中学校の第2学年を対象に授業と家庭学習を連携させる実践を行い，生徒の「主体的・自律的な学び」を萌芽させることを目指した。教師が学習方略や目標設定の重要性を伝え，メタ認知を促すことで，生徒は自己調整学習のサイクルを意識し，自分なりの学習方略を探求するようになった。また，家庭学習で授業につながる課題に取り組むことで，授業への主体的な参加と，授業外で自律的に学ぶ意欲が促されることも示唆された。 en-copyright= kn-copyright= en-aut-name=TANAKAJunko en-aut-sei=TANAKA en-aut-mei=Junko kn-aut-name=田中純子 kn-aut-sei=田中 kn-aut-mei=純子 aut-affil-num=1 ORCID= en-aut-name=MISAWARyo en-aut-sei=MISAWA en-aut-mei=Ryo kn-aut-name=三沢良 kn-aut-sei=三沢 kn-aut-mei=良 aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama Municipal Hosen Junior High School kn-affil=岡山市立芳泉中学校 affil-num=2 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=授業と家庭学習の連携 (coordination between classroom and home learning) kn-keyword=授業と家庭学習の連携 (coordination between classroom and home learning) en-keyword=自己調整学習 (self-regulated learning) kn-keyword=自己調整学習 (self-regulated learning) en-keyword=宿題 (homework) kn-keyword=宿題 (homework) en-keyword=授業改善 (lesson improvement) kn-keyword=授業改善 (lesson improvement) END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250316 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel pulmonary abdominal normothermic regional perfusion circuit for simultaneous in-donor evaluation and preservation of lungs and abdominal organs in donation after circulatory death en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective To overcome limitations of traditional ex vivo lung perfusion (EVLP) for controlled donation after circulatory death (cDCD) lungs, this study aimed to evaluate a novel pulmonary abdominal normothermic regional perfusion (PANRP) technique, which we uniquely designed, for in situ assessment of lungs from cDCD donors.
Methods We modified the abdominal normothermic regional perfusion circuit for simultaneous lung and abdominal organ assessment using independent extracorporeal membrane oxygenation components. Blood was oxygenated via a membrane oxygenator and returned to the body, with pulmonary flow adjusted to maintain pressure < 25 mmHg. Femoral cannulation was performed, and the lungs were ventilated with standard settings. Organ function was assessed over 2 h using PaO2/FiO2, AST, ALT, BUN, and Cr measurements to monitor perfusion and oxygen delivery.
Results PANRP maintained stable lung function, with P/F ratios above 300, and preserved abdominal organ parameters, including stable AST, ALT, BUN, and Cr levels. Adequate urine output was observed, indicating normal renal function. Pulmonary artery pressure remained < 20 mmHg, and pulmonary vascular resistance was kept at 400 dyn・s/cm5, showing no signs of lung dysfunction or injury throughout the circuit.
Conclusions PANRP offers a promising alternative to traditional EVLP for cDCD lung evaluation, allowing in situ assessment of multiple organs simultaneously. This approach may overcome logistical and economic challenges associated with ex vivo techniques, enabling a more efficient evaluation process. Further studies are warranted to confirm its clinical applicability and impact on long-term outcomes. en-copyright= kn-copyright= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UmedaMasashi en-aut-sei=Umeda en-aut-mei=Masashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UjikeHiroyuki en-aut-sei=Ujike en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TomiokaYasuaki en-aut-sei=Tomioka en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery, Shimane University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of General Thoracic and Breast and Endocrinological Surgery, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Lung preservation kn-keyword=Lung preservation en-keyword=Donation after circulatory death kn-keyword=Donation after circulatory death en-keyword=Abdominal normothermic regional perfusion kn-keyword=Abdominal normothermic regional perfusion END start-ver=1.4 cd-journal=joma no-vol=195 cd-vols= no-issue= article-no= start-page=123743 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202503 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Surgical Simulation for Tubular Retractor Surgery Using Three-Dimensional Printed Intraventricular Tumor Models: Case Series en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The utility of the tubular retractor for deep-seated tumors, including intraventricular tumors, has recently been reported. However, the surgical field’s depth and narrowness can lead to blind spots, and it is crucial to prevent damage to the cortex and white matter fibers in eloquent areas. Therefore, preoperative simulation is critical for tubular retractor surgery. In this study, we investigated the benefits of threedimensional (3D)-printed intraventricular tumor models for tubular retractor surgery.
Methods: Nine patients with intraventricular central neurocytoma who underwent tubular retractor surgery at our institution between March 2013 and August 2023 were retrospectively reviewed. Fusion images and 3D-printed intraventricular tumor models were developed from preoperative computed tomography (CT) and magnetic resonance imaging (MRI). The puncture points of the tubular retractor were simulated using fusion images and 3D-printed intraventricular tumor models by 11 neurosurgeons (3 experts in brain tumors, 2 experts in areas other than brain tumors, and 6 residents). The dispersion of puncture points among 8 neurosurgeons (excluding brain tumor experts) was compared in each simulation model.
Results: These cases were categorized into two groups based on the dispersion of puncture points simulated by fusion images. Puncture point dispersion was markedly smaller in all cases when using 3D-printed intraventricular tumor models compared to simulations solely based on fusion images.
Conclusions: In intraventricular tumor surgery using a tubular retractor, 3D-printed intraventricular tumor models proved more beneficial in preoperative simulation compared to fusion images. en-copyright= kn-copyright= en-aut-name=OmaeRyo en-aut-sei=Omae en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraRyu en-aut-sei=Kimura en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SaijoTomoya en-aut-sei=Saijo en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujitaJuntaro en-aut-sei=Fujita en-aut-mei=Juntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishigakiShohei en-aut-sei=Nishigaki en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IkemachiRyosuke en-aut-sei=Ikemachi en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=3D-printed model kn-keyword=3D-printed model en-keyword=Case series kn-keyword=Case series en-keyword=Intraventricular tumors kn-keyword=Intraventricular tumors en-keyword=Preoperative surgical simulation kn-keyword=Preoperative surgical simulation en-keyword=Tubular retractor kn-keyword=Tubular retractor END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=5248 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes of leucine-rich alpha 2 glycoprotein could be a marker of changes of endoscopic and histologic activity of ulcerative colitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Leucine-rich alpha 2 glycoprotein (LRG) is one of the serum biomarkers for disease activity of ulcerative colitis (UC). We focused on the correlation between the changes of LRG and the changes of endoscopic and histologic activity of UC, in comparison to the changes of fecal calprotectin (Fcal), fecal immunochemical test (FIT), and C-reactive protein (CRP). Seventy-nine patients with two or more colonoscopies were enrolled, and 123 paired colonoscopies and 121 paired biopsies were examined. With regard to the change of endoscopic/histologic activity between the preceding and subsequent colonoscopy, there was improvement (n = 29/45), unchanging (n = 63/36), and worsening (n = 31/40). The correlations between the changes of marker levels and endoscopic/histologic activity were Fcal; r = 0.50/0.39 and FIT; r = 0.41/0.40, LRG; r = 0.42/0.40 and CRP; r = 0.22/0.17. Furthermore, when the correlation between the changes of LRG levels and the changes of endoscopic/histological activity was compared with those of other markers, the correlation of LRG tended to be superior to those of CRP (CRP vs. LRG; p = 0.08/0.01). LRG is equivalent to fecal markers and superior to CRP, when inferring changes in disease activity of UC based on changes in its level. en-copyright= kn-copyright= en-aut-name=AoyamaYuki

Polyamines en-subtitle= kn-subtitle= en-abstract= kn-abstract=Biofouling, which is the accumulation of organisms on undersea structures, poses significant global, social, and economic issues. Although organotin compounds were effective antifoulants since the 1960s, they were banned in 2008 due to their toxicity to marine life. Although tin-free alternatives have been developed, they also raise environmental concerns. This underscores the need for effective, nontoxic antifouling agents. We previously synthesized N-(4-aminobutyl)propylamine (xylemin) and its structural analogs. In this study, we assayed the antifouling activity and toxicity of xylemin, its structural analogs, and related polyamines toward cypris larvae of the barnacle Amphibalanus amphitrite. Xylemin and its Boc-protected analog exhibited antifouling activities with 50% effective concentrations (EC50) of 4.25 and 6.11 µg/mL, respectively. Four xylemin analogs did not show a settlement-inhibitory effect at a concentration of 50 µg/mL. Putrescine, spermidine, spermine, and thermospermine, which are xylemin-related polyamines, did not display antifoulant effects (EC50 > 50 µg/mL). All evaluated compounds were nontoxic at a concentration of 50 µg/mL. These findings indicate that the size and structure of the N-alkyl group are essential for the antifouling activity of xylemin. Therefore, xylemin and its analogs hold promise as nontoxic, eco-friendly antifouling agents, offering a sustainable solution to biofouling in marine environments. en-copyright= kn-copyright= en-aut-name=TakamuraHiroyoshi en-aut-sei=Takamura en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YorisueTakefumi en-aut-sei=Yorisue en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKenta en-aut-sei=Tanaka en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KadotaIsao en-aut-sei=Kadota en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Institute of Natural and Environmental Sciences, University of Hyogo kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Department of Chemistry, Graduate School of Natural Science and Technology, Okayama University kn-affil= en-keyword=Amines kn-keyword=Amines en-keyword=Antifouling activity kn-keyword=Antifouling activity en-keyword=Barnacle kn-keyword=Barnacle en-keyword=Structure–activity relationships kn-keyword=Structure–activity relationships en-keyword=Xylemin kn-keyword=Xylemin END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=2 article-no= start-page=e79852 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250228 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Presumed Autoimmune Keratitis in Both Eyes Without Systemic Manifestations: A 40-Year Course of a Patient With Corneal Infiltrates and Melt en-subtitle= kn-subtitle= en-abstract= kn-abstract=Peripheral corneal infiltration, corneal ulcer, and melt are recognized complications linked to systemic immunological diseases, such as antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis. These manifestations, which occur in isolation, might be autoimmune keratitis but are difficult to prove underlying immunological abnormalities. This report described a patient with presumed autoimmune keratitis who repeatedly presented corneal infiltration and perforation in both eyes even after penetrating keratoplasty. The 68-year-old patient with a stable condition of keratoconjunctivitis sicca, in a 28-year follow-up, abruptly developed mild infiltrates in the corneal center of the right eye and white dense infiltrates in the peripheral and central cornea of the left eye. He was treated with topical 0.1% betamethasone eye drops and oral prednisolone tapering from 30 mg daily. The patient underwent cataract surgeries in both eyes 10 months after the onset of corneal infiltration and subsequently underwent penetrating keratoplasty in both eyes due to abrupt corneal perforation in the left eye 14 months after the onset of corneal infiltration. Six months post-keratoplasty, he experienced a recurrence of infiltrates in the corneal grafts in both eyes, leading to corneal leukoma in the left eye. The corneal graft in the right eye maintained its integrity with relatively mild opacity until approximately 3.5 years post-keratoplasty, when he abruptly developed white dense infiltration of both the corneal graft and his own peripheral cornea at the age of 73. In response to oral prednisolone tapered from 15 mg daily, the corneal infiltration in the right eye resolved but resulted in graft failure. Since he did not exhibit systemic symptoms and signs throughout the course, the repeat episodes of infiltration in both his own cornea and the corneal graft would be the manifestations of autoimmune keratitis. The entity of autoimmune keratitis in isolation would be beneficial to establish a therapeutic strategy for long-term immunosuppression in light of a risk for steroid side effects and a high rate of corneal graft failure. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=autoimmune keratitis kn-keyword=autoimmune keratitis en-keyword=corneal graft kn-keyword=corneal graft en-keyword=corneal infiltration kn-keyword=corneal infiltration en-keyword=corneal melt kn-keyword=corneal melt en-keyword=penetrating keratoplasty kn-keyword=penetrating keratoplasty END start-ver=1.4 cd-journal=joma no-vol=111 cd-vols= no-issue=6 article-no= start-page=064502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Josephson effect and odd-frequency pairing in superconducting junctions with unconventional magnets en-subtitle= kn-subtitle= en-abstract= kn-abstract=We consider Josephson junctions formed by coupling two conventional superconductors via an unconventional magnet and investigate the formation of Andreev bound states, their impact on the Josephson effect, and the emergent superconducting correlations. In particular, we focus on unconventional magnets known as 𝑑-wave altermagnets and 𝑝-wave magnets. We find that the Andreev bound states in 𝑑-wave altermagnet and 𝑝𝑦-wave magnet Josephson junctions strongly depend on the transverse momentum, with a spin splitting and low-energy minima as a function of the superconducting phase difference 𝜑. In contrast, the Andreev bound states for 𝑝𝑥-wave magnets are insensitive to the transverse momentum. We then show that the Andreev bound states can be probed by the local density of states in the middle of the junction, which also reveals that 𝑑𝑥2−𝑦2- and 𝑝-wave magnet junctions are prone to host zero energy peaks. While the zero-energy peak in 𝑑𝑥2−𝑦2-wave altermagnet junctions tends to oscillate with the magnetic order, it remains robust in 𝑝-wave magnet junctions. We then discover that the Josephson current in 𝑑-wave altermagnet junctions is composed of higher harmonics of 𝜑, which originate a 𝜙-Josephson junction behavior entirely controlled by the magnetic order in 𝑑𝑥⁢𝑦-wave altermagnets. In contrast, the Josephson current in Josephson junctions with 𝑝-wave magnets exhibits a conventional sinelike profile with a fast sign change at 𝜑=𝜋 due to zero-energy Andreev bound states. We also demonstrate that the critical currents in 𝑑-wave altermagnet Josephson junctions exhibit an oscillatory decay with the increase of the magnetic order, while the oscillations are absent in 𝑝-wave magnet junctions albeit the currents exhibit a slow decay. Furthermore, we also demonstrate that the interplay of the Josephson effect and unconventional magnetic order of 𝑑-wave altermagnets and 𝑝-wave magnets originates from odd-frequency spin-triplet 𝑠-wave superconducting correlations that are otherwise absent. Our results can serve as a guide to pursue the new functionality of Josephson junctions based on unconventional magnets. en-copyright= kn-copyright= en-aut-name=FukayaYuri en-aut-sei=Fukaya en-aut-mei=Yuri kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MaedaKazuki en-aut-sei=Maeda en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YadaKeiji en-aut-sei=Yada en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=CayaoJorge en-aut-sei=Cayao en-aut-mei=Jorge kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaYukio en-aut-sei=Tanaka en-aut-mei=Yukio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=LuBo en-aut-sei=Lu en-aut-mei=Bo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Faculty of Environmental Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=3 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=4 en-affil=Department of Physics and Astronomy, Uppsala University kn-affil= affil-num=5 en-affil=Department of Applied Physics, Nagoya University kn-affil= affil-num=6 en-affil=Center for Joint Quantum Studies, Tianjin Key Laboratory of Low Dimensional Materials Physics and Preparing Technology, Department of Physics, Tianjin University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=2 article-no= start-page=376 end-page=382 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250205 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A case of pancreatic ductal adenocarcinoma growing within the pancreatic duct mimicking an intraductal tubulopapillary neoplasm en-subtitle= kn-subtitle= en-abstract= kn-abstract=We herein report a case of pancreatic ductal adenocarcinoma (PDAC) that developed within the pancreatic duct and was initially diagnosed as an intraductal tubulopapillary neoplasm (ITPN). A 76-year-old man presented with weight loss and main pancreatic duct dilation. The imaging studies revealed a 30-mm hypovascular tumor within the main duct of the pancreatic head. An endoscopic examination with a biopsy revealed high-grade atypical epithelial cells with immunostaining patterns suggestive of ITPN. Following robot-assisted pancreaticoduodenectomy, postoperative pathology revealed conflicting features: nodular/cribriform infiltrations typical of ITPN and non-lobular replacement with scattered infiltrations characteristic of PDAC. A comprehensive genomic profiling test detected KRAS and TP53 mutations, leading to the final diagnosis of PDAC (fT3N1aM0, stage IIB). The patient received adjuvant S-1 chemotherapy and remained recurrence-free for 15 months post-surgery. This case highlights the diagnostic challenges of differentiating intraductal pancreatic tumors and demonstrates the utility of integrating genetic testing with conventional diagnostic modalities for an accurate diagnosis and appropriate treatment selection. en-copyright= kn-copyright= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakagiKosei en-aut-sei=Takagi en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Pathology, Dentistry and Pharmaceutical Science, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=Pancreatic intraductal neoplasms kn-keyword=Pancreatic intraductal neoplasms en-keyword=Pancreatic carcinoma kn-keyword=Pancreatic carcinoma en-keyword=Intraductal tubulopapillary neoplasm kn-keyword=Intraductal tubulopapillary neoplasm en-keyword=Genetic testing kn-keyword=Genetic testing END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=51 end-page=58 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photoinitiators Induce Histamine Production in Human Mast Cells en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photoinitiators are used in the manufacture of many daily products, and may produce harmful effects due to their cytotoxicity. They have also been detected in human serum. Here, we investigated the histamine-producing effects in HMC-1 cells and the inflammatory cytokine release effects in RAW264 cells for four photoinitiators: 1-hydroxycyclohexyl phenyl ketone; 2-isopropylthioxanthone; methyl 2-benzoylbenzoate; and 2-methyl-4´-(methylthio)-2-morpholinopropiophenone. All four promoted histamine production in HMC-1 cells; however, they did not significantly affect the release of inflammatory cytokines in RAW264 cells. These findings suggest that these four photoinitiators induce inflammatory cytokine-independent histamine production, potentially contributing to histamine-mediated chronic inflammation in vitro. en-copyright= kn-copyright= en-aut-name=MiuraTaro en-aut-sei=Miura en-aut-mei=Taro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KawasakiYoichi en-aut-sei=Kawasaki en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HamanoHirofumi en-aut-sei=Hamano en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ZamamiYoshito en-aut-sei=Zamami en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SendoToshiaki en-aut-sei=Sendo en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Laboratory of Clinical Pharmacology and Therapeutics, Kagawa School of Pharmaceutical Sciences, Tokushima Bunri University kn-affil= affil-num=3 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Clinical Pharmacy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=photoinitiator kn-keyword=photoinitiator en-keyword=ink kn-keyword=ink en-keyword=injection kn-keyword=injection en-keyword=histamine kn-keyword=histamine en-keyword=inflammation kn-keyword=inflammation END start-ver=1.4 cd-journal=joma no-vol=79 cd-vols= no-issue=1 article-no= start-page=9 end-page=19 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=202502 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gastrectomy Causes an Imbalance in the Trunk Muscles en-subtitle= kn-subtitle= en-abstract= kn-abstract=Muscle loss negatively affects gastrectomy prognosis. However, muscle loss is recognized as a systemic change, and individual muscle function is often overlooked. We investigated changes in the muscle volume of individual muscles after gastrectomy to identify clues for prognostic factors and optimal rehabilitation programs. Patients who underwent R0 gastrectomy for Stage I gastric cancer at our hospital from 2015 to 2021 were retrospectively selected to minimize the effects of malignancy and chemotherapy. Trunk muscle volume was measured by computed tomography to analyze body composition changes. Statistical analysis was performed to identify risk factors related to body composition changes. We compared the preoperative and 6-month postoperative conditions of 59 patients after gastrectomy. There was no difference in the psoas major muscle, a conventional surrogate marker of sarcopenia. There were significant decreases in the erector spinae (p=0.01) and lateral abdominal (p=0.01) muscles, and a significant increase in the rectus abdominis muscle (p=0.02). No significant correlation was found between these muscle changes and nutritional status. Body composition imbalance may serve as a new indicator of the general condition of patients after gastrectomy. Rehabilitation to correct this imbalance may improve prognosis after gastrectomy. en-copyright= kn-copyright= en-aut-name=IkeyaNanami en-aut-sei=Ikeya en-aut-mei=Nanami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkitaAtsushi en-aut-sei=Okita en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HashidaShinsuke en-aut-sei=Hashida en-aut-mei=Shinsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamamotoSumiharu en-aut-sei=Yamamoto en-aut-mei=Sumiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IkedaHirokuni en-aut-sei=Ikeda en-aut-mei=Hirokuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukudaKazunori en-aut-sei=Tsukuda en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Okayama City Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=skeletal muscle kn-keyword=skeletal muscle en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=gastrectomy kn-keyword=gastrectomy en-keyword=erector spinae muscle kn-keyword=erector spinae muscle END start-ver=1.4 cd-journal=joma no-vol=172 cd-vols= no-issue=2 article-no= start-page=471 end-page=479 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250122 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of factors related to functional prognoses in craniopharyngiomas en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose Craniopharyngiomas are histologically benign tumors, but their proximity to vital neurovascular structures can significantly deteriorate functional prognoses and severely restrict patients’ social interaction and activity. We retrospectively identified risk factors related to the functional prognoses in patients with craniopharyngioma treated at our center.
Methods A retrospective analysis was conducted on 40 patients who underwent surgery for craniopharyngioma and follow-up at our institution between 2003 and 2022. Functional prognoses were evaluated in terms of obesity (body mass index [BMI] ≥ 25 for adults, BMI-Z ≥ 1.65 for children), visual function, endocrine function, and social participation. We investigated whether patient characteristics, tumor size, tumor location, hypothalamic involvement, surgical hypothalamic damage, extent of resection, and recurrence rate correlated with these functional prognostic factors.
Results The median age at diagnosis was 28.0 years, with a median follow-up of 80.5 months. Postoperative obesity was present in 22 patients, and those with postoperative obesity had a significantly higher preoperative BMI or BMI-Z (preoperative BMI for adults: p = 0.074; preoperative BMI-Z for children: p = 0.020) and were significantly correlated with preoperative hypothalamic involvement grade 2 (p = 0.012) and surgical hypothalamic damage grade II (p = 0.0001). Deterioration in social participation was significantly associated with a larger tumor size (p = 0.023) and tumor recurrence (p = 0.0047).
Conclusions Patients with higher preoperative BMI or BMI-Z and hypothalamic involvement have a greater risk of postoperative obesity, and larger tumor size and recurrence can significantly deteriorate the rate of patients’ social participation. en-copyright= kn-copyright= en-aut-name=UmedaTsuyoshi en-aut-sei=Umeda en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID=

en-title= kn-title=Characteristics and outcomes of subarachnoid hemorrhage from vertebral artery dissection: A comparative study with other non-traumatic etiologies en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: Vertebral artery dissection (VAD) is a rare cause of non-traumatic subarachnoid hemorrhage (SAH) with significant clinical implications. This study compared the clinical characteristics and outcomes of SAH from intracranial VAD rupture to those from other etiologies, primarily aneurysmal rupture.
Methods: This single-center retrospective cohort study at Okayama University Hospital included patients with non-traumatic SAH diagnosed between 2019 and 2023. Patients were categorized into "VAD rupture" and "other etiologies" groups. The main outcome was clinical presentation and symptoms. Additional outcomes included ICU mortality, in-hospital mortality, and unfavorable outcomes at discharge and 6 months, defined as a modified Rankin Scale score of 3-6.
Results: A total of 66 patients were included, with 14 in the VAD rupture group and 52 in the other etiologies group. The VAD rupture group was younger (median age 49 vs. 64 years, p = 0.003) and had a higher incidence of out-of-hospital cardiac arrest (42.9% vs. 9.6%, p = 0.011). Preceding headache was more common in the VAD rupture group (78.6% vs. 11.5%, p < 0.001), with a median duration of 36 h before presentation. ICU and in-hospital mortality was higher in the VAD rupture group (both 50.0% vs. 19.3%, p = 0.019). No significant differences were found in unfavorable neurological outcomes at hospital discharge and 6 months.
Conclusions: VAD-related SAH often presents with prodromal headaches, severe symptoms like out-of-hospital cardiac arrest, and higher ICU and in-hospital mortality than other SAH causes, though long-term outcomes are similar. Larger, prospective studies are needed to refine interventions. en-copyright= kn-copyright= en-aut-name=OshitaShu en-aut-sei=Oshita en-aut-mei=Shu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=JinnoShunta en-aut-sei=Jinno en-aut-mei=Shunta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuoIppei en-aut-sei=Matsuo en-aut-mei=Ippei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HongoTakashi en-aut-sei=Hongo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiramatsuMasafumi en-aut-sei=Hiramatsu en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HarumaJun en-aut-sei=Haruma en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SugiuKenji en-aut-sei=Sugiu en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Okayama University Medical School kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=headache kn-keyword=headache en-keyword=intracranial aneurysm kn-keyword=intracranial aneurysm en-keyword=prodromal symptoms kn-keyword=prodromal symptoms en-keyword=subarachnoid hemorrhage kn-keyword=subarachnoid hemorrhage en-keyword=vertebral artery dissection kn-keyword=vertebral artery dissection END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=23 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Psychogenic fever and neurodevelopmental disorders among Japanese children en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Psychosocial stress can induce various physical symptoms, including fever, which is a commonly seen symptom in pediatric practice. In cases of unexplained fever, psychogenic fever should be considered as a potential cause. Children with neurodevelopmental disorders may be more vulnerable to stress and therefore more prone to developing somatic symptoms than their peers. This study aimed to elucidate the characteristics of children with psychogenic fever and comorbidity.
Methods This study included 21 patients with psychogenic fever who visited the Department of Pediatric Psychosomatic Medicine, Okayama University Hospital. Information on age, sex, disease onset, final estimated diagnosis, comorbidities, treatment course, and outcome was obtained from the patients' medical records.
Results Of the 21 patients included, 7 were boys and 14 were girls, and their median age was 13.0 (range: 8.6-14.6) years. A total of 19 patients had no attendance at school, and all patients showed signs of maladjustment in school. The comorbidities included orthostatic dysregulation (n = 4) and migraine (n = 3). Neurodevelopmental disorders were observed in nine patients, eight of whom were diagnosed after the initial visit. The mean treatment duration was 37.2 months. The outcomes were complete remission (n = 9), improvement (n = 4), discontinuation (n = 1), and referral to another physician (n = 7).
Conclusion Various comorbidities were observed in the patients of this study with psychogenic fever, including the coexistence of neurodevelopmental disorders, such as autistic spectrum disorder. Children with neurodevelopmental disorders are prone to psychological stress resulting from difficulties in social adjustment. It is crucial to understand the developmental characteristics and environmental adaptation of patients to facilitate accurate diagnosis and treatment. en-copyright= kn-copyright= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShigeyasuYoshie en-aut-sei=Shigeyasu en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HanzawaMana en-aut-sei=Hanzawa en-aut-mei=Mana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HoriuchiMakiko en-aut-sei=Horiuchi en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pediatrics, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Psychogenic fever kn-keyword=Psychogenic fever en-keyword=Functional hyperthermia kn-keyword=Functional hyperthermia en-keyword=Neurodevelopmental disorder kn-keyword=Neurodevelopmental disorder en-keyword=Autism spectrum disorder kn-keyword=Autism spectrum disorder en-keyword=Environmental adaptation kn-keyword=Environmental adaptation END start-ver=1.4 cd-journal=joma no-vol=159 cd-vols= no-issue=19 article-no= start-page=194504 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficiency and energy balance for substitution of CH4 in clathrate hydrates with CO2 under multiple-phase coexisting conditions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Many experimental and theoretical studies on CH4–CO2 hydrates have been performed aiming at the extraction of CH4 as a relatively clean energy resource and concurrent sequestration of CO2. However, vague or insufficient characterization of the environmental conditions prevents us from a comprehensive understanding of even equilibrium properties of CH4–CO2 hydrates for this substitution. We propose possible reaction schemes for the substitution, paying special attention to the coexisting phases, the aqueous and/or the fluid, where CO2 is supplied from and CH4 is transferred to. We address the two schemes for the substitution operating in three-phase and two-phase coexistence. Advantages and efficiencies of extracting CH4 in the individual scheme are estimated from the chemical potentials of all the components in all the phases involved in the substitution on the basis of a statistical mechanical theory developed recently. It is found that although substitution is feasible in the three-phase coexistence, its working window in temperature–pressure space is much narrower compared to the two-phase coexistence condition. Despite that the substitution normally generates only a small amount of heat, a large endothermic substitution is suggested in the medium pressure range, caused by the vaporization of liquid CO2 due to mixing with a small amount of the released CH4. This study provides the first theoretical framework toward the practical use of hydrates replacing CH4 with CO2 and serves as a basis for quantitative planning. en-copyright= kn-copyright= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=3 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=21 article-no= start-page=2875 end-page=2884 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic and Histological Gastritis in University Students with Helicobacter pylori Infection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective Although the characteristics of Helicobacter pylori infection have been extensively reported, there is a lack of consensus regarding its characteristics in young adults. The present study examined the endoscopic and histological characteristics of young adults who underwent eradication therapy for H. pylori infection.
Methods We examined the H. pylori infection status of first-year students at Okayama University School of Medicine and Dentistry between 2014 and 2020. A total of 152 (6.8%) students who were positive for H. pylori antibody or pepsinogen tests were enrolled in the study. Among them, 107 students underwent endoscopy, and their biopsy samples were investigated. Seventy-five students were diagnosed with H. pylori infections.
Results Of 75 H. pylori-positive patients, 57 (76.0%) had endoscopic atrophic gastritis, and 42 (56.0%) had histological atrophy. A few patients had severe atrophic gastritis. All 65 patients who underwent an eradication assessment were successfully treated. After successful eradication, 26 patients underwent endoscopic follow-up. The mean follow-up period was 32.9 months. A histological evaluation revealed that gastric antrum atrophy had subsided in 11 of 14 patients, and atrophy in the lesser curvature of the gastric body had subsided in 7 of 8 patients.
Conclusion More than half of young adults with H. pylori infection had atrophic gastritis. We found mild atrophy in young adults, which subsided shortly after eradication treatment. This study provides a foundation for future studies to evaluate the validity of eradication therapy in preventing gastric cancer in patients. en-copyright= kn-copyright= en-aut-name=OkanoueShotaro en-aut-sei=Okanoue en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SakaeHiroyuki en-aut-sei=Sakae en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokotaKenji en-aut-sei=Yokota en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObayashiYuka en-aut-sei=Obayashi en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AbeMakoto en-aut-sei=Abe en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Bacteriology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=atrophic gastritis kn-keyword=atrophic gastritis en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=Helicobacter pylori kn-keyword=Helicobacter pylori en-keyword=young adults kn-keyword=young adults en-keyword=eradication kn-keyword=eradication END start-ver=1.4 cd-journal=joma no-vol=145 cd-vols= no-issue=8 article-no= start-page=881 end-page=896 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250220 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oral Inflammation and Microbiome Dysbiosis Exacerbate Chronic Graft-versus-host Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=The oral microbiota, second in abundance to the gut, is implicated in chronic systemic diseases, but its specific role in graft-versus-host disease (GVHD) pathogenesis has been unclear. Our study finds that mucositis-induced oral dysbiosis in patients after hematopoietic cell transplantation (HCT) associated with increased chronic GVHD (cGVHD), even in patients receiving posttransplant cyclophosphamide. In murine HCT models, oral dysbiosis caused by bilateral molar ligatures exacerbated cGVHD and increased bacterial load in the oral cavity and gut, with Enterococcaceae significantly increasing in both organs. In this model, the migration of Enterococcaceae to cervical lymph nodes both before and after transplantation activated antigen-presenting cells, thereby promoting the expansion of donor-derived inflammatory T cells. Based on these results, we hypothesize that pathogenic bacteria increase in the oral cavity might not only exacerbate local inflammation but also enhance systemic inflammation throughout the HCT course. Additionally, these bacteria translocated to the gut and formed ectopic colonies, further amplifying systemic inflammation. Furthermore, interventions targeting the oral microbiome mitigated murine cGVHD. Collectively, our findings highlight the importance of oral dysbiosis in cGVHD and suggest that modulation of the oral microbiome during transplantation may be an effective approach for preventing or treating cGVHD. en-copyright= kn-copyright= en-aut-name=KambaraYui en-aut-sei=Kambara en-aut-mei=Yui kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraHideaki

cell injury and vascular leakage in lung transplantation from circulatory-death donor en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Ischemia-reperfusion injury (IRI) stands as a major trigger for primary graft dysfunction (PGD) in lung transplantation (LTx). Especially in LTx from donation after cardiac death (DCD), effective control of IRI following warm ischemia (WIRI) is crucial to prevent PGD. This study aimed to identify the key factors affecting WIRI in LTx from DCD.
Methods: Previously reported RNA-sequencing dataset of lung WIRI was reanalyzed to identify nuclear receptor subfamily 4 group A member 1 (NR4A1) as the immediate early gene for WIRI. Dynamics of NR4A1 expression were verified using a mouse hilar clamp model. To investigate the role of NR4A1 in WIRI, a mouse model of LTx from DCD was established using Nr4a1 knockout (Nr4a1−/−) mice.
Results: NR4A1 was located around vascular cells, and its protein levels in the lungs increased rapidly and transiently during WIRI. LTｘ from Nr4a1−/− donors significantly improved pulmonary graft function compared to wild-type donors. Histological analysis showed decreased microvascular endothelial cell death, neutrophil infiltration, and albumin leakage. Evans blue permeability assay demonstrated maintained pulmonary microvascular barrier integrity in grafts from Nr4a1−/− donors, correlating with diminished pulmonary edema. However, NR4A1 did not significantly affect the inflammatory response during WIRI, and IRI was not suppressed when a wild-type donor lung was transplanted into the Nr4a1−/− recipient.
Conclusions: Donor NR4A1 plays a specialized role in the positive regulation of endothelial cell injury and microvascular hyperpermeability. These findings demonstrate the potential of targeting NR4A1 interventions to alleviate PGD and improve outcomes in LTx from DCD. en-copyright= kn-copyright= en-aut-name=KawanaShinichi en-aut-sei=Kawana en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SakaueTomohisa en-aut-sei=Sakaue en-aut-mei=Tomohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashimotoKohei en-aut-sei=Hashimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakataKentaro en-aut-sei=Nakata en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ChoshiHaruki en-aut-sei=Choshi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OhtaniShinji en-aut-sei=Ohtani en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OharaToshiaki en-aut-sei=Ohara en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MatsukawaAkihiro en-aut-sei=Matsukawa en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular and Thoracic Surgery, Ehime University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Surgery, Division of Cardiovascular and Thoracic Surgery, Duke University School of Medicine kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cell Growth and Tumor Regulation, Proteo-Science Center (PROS), Ehime University kn-affil= affil-num=10 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Pathology and Experimental Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=ischemia-reperfusion injury kn-keyword=ischemia-reperfusion injury en-keyword=donation after circulatory death kn-keyword=donation after circulatory death en-keyword=nuclear receptor subfamily 4 group A member 1 kn-keyword=nuclear receptor subfamily 4 group A member 1 en-keyword=endothelial cell kn-keyword=endothelial cell END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=e70097 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250107 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Eyelid Spindle Cell Lipoma: Case Report and Review of Three Patients in Literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 39-year-old woman presented a saucer-shaped mass in the left upper eyelid and underwent the extirpation at local anesthesia.

Here we report a 65-year-old woman, as a hepatitis B virus (HBV) carrier, who presented concurrently a liver mass and lower bulbar conjunctival pigmented lesions in the right eye. Needle liver biopsy and excisional conjunctival biopsy showed hepatocellular carcinoma and conjunctival malignant melanoma in situ, respectively. The priority was given to segmental liver resection for hepatocellular carcinoma after transcatheter arterial chemoembolization. In 1 year, she underwent second and third resection of bulbar conjunctival pigmented lesions, and the pathological examinations constantly showed melanoma in situ. In the course, she showed gradual widening of pigmented lesions to upper bulbar conjunctiva and lower palpebral conjunctiva and lower eyelid. About 2.5 years from the initial visit, the lower eyelid lesion was resected for a genomic DNA-based test of BRAF mutations which turned out to be absent, and then, she began to have intravenous anti-programmed cell death-1 (PD-1), nivolumab every 3 or 4 weeks. She developed iritis in the right eye with conjunctival melanoma as an immune-related adverse event, 3 months after the beginning of nivolumab, and so she used daily topical 0.1% betamethasone eye drops to control the intraocular inflammation. She showed no metastasis in 6 years of follow-up, but later in the course, 5 years from the initial visit, she developed abruptly a non-pigmented nodular lesion on the temporal side of the bulbar conjunctiva along the corneal limbus, accompanied by two pigmented nodular lesions in the upper and lower eyelids in a few months. She thus, underwent proton beam therapy toward the conjunctival melanoma and achieved the successful local control. Proton beam therapy is a treatment option in place of orbital exenteration, and multidisciplinary team collaboration is desirable to achieve better cosmetic and functional outcomes in conjunctival malignant melanoma. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgataTakeshi en-aut-sei=Ogata en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WakiTakahiro en-aut-sei=Waki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TachibanaKota en-aut-sei=Tachibana en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AdachiTakuya en-aut-sei=Adachi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiOsamu en-aut-sei=Yamasaki en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Regenerative and Reconstructive Medicine (Ophthalmology), Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Proton Beam Center, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Proton Beam Center, Tsuyama Chuo Hospital kn-affil= affil-num=4 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Dermatology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Ocular surface kn-keyword=Ocular surface en-keyword=Conjunctiva kn-keyword=Conjunctiva en-keyword=Malignant melanoma kn-keyword=Malignant melanoma en-keyword=Proton beam therapy kn-keyword=Proton beam therapy en-keyword=Nivolumab kn-keyword=Nivolumab en-keyword=PD-1 inhibitor kn-keyword=PD-1 inhibitor en-keyword=Immune checkpoint inhibitor kn-keyword=Immune checkpoint inhibitor END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=1500023 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241203 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Trabecular bone scores in children with osteogenesis imperfecta respond differently to bisphosphonate treatment depending on disease severity en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Osteogenesis imperfecta (OI) is a congenital skeletal disorder characterized by bone fragility. Bisphosphonates (BISs) have become the mainstream treatment in children with OI. However, an optimal treatment protocol has not yet been established, while BIS treatment tends to be administered to normalize bone mineral density (BMD). Bone quality is an important component of bone strength. The trabecular bone score (TBS) is a quantitative measure of the microstructure that affects bone quality. This study investigated the TBS during BIS treatment in children with OI. Materials and methods: Twenty-nine children with OI were enrolled and classified into two groups: mild (type 1) and moderate to severe (types 3 and 4). Dual-energy x-ray absorptiometry images were retrospectively analyzed for TBS calculation. The relationship between the areal BMD (aBMD), its Z-score, height-adjusted BMD (BMDHAZ) Z-score, TBS, and TBS Z-score with the treatment duration was assessed for each group. Results: In the mild group, the aBMD, its Z-score, and BMDHAZ Z-score showed a significant positive correlation with treatment duration (r = 0.68, 0.68, 0.72, respectively, p < 0.01). The TBS Z-score tended to increase with treatment duration, albeit without reaching significance. In the moderate to severe group, the TBS Z-score showed a significant positive correlation with treatment duration (r = 0.48, p < 0.01), in contrast to the aBMD Z-score, which did not increase. Finally, the BMDHAZ Z-score only showed a weak positive correlation with treatment duration (r = 0.37, p < 0.01). Conclusion: Because BIS affect the BMD and TBS differently based on the severity of OI, treatment goals may need to be stratified by disease severity. en-copyright= kn-copyright= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaHiroyuki en-aut-sei=Tanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama Saiseikai General Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone density kn-keyword=bone density en-keyword=osteoporosis kn-keyword=osteoporosis en-keyword=bone diseases kn-keyword=bone diseases en-keyword=connective tissue kn-keyword=connective tissue en-keyword=child kn-keyword=child END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=475 end-page=483 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=C-arm Free Unilateral Biportal Endoscopic Discectomy: A Technical Note en-subtitle= kn-subtitle= en-abstract= kn-abstract=This report presents a new unilateral biportal endoscopic (UBE) technique for lumbar disc herniation without C-arm guidance. Lumbar disc herniation requires surgical intervention when conservative methods fail. Shifts towards minimally invasive percutaneous endoscopic lumbar discectomy, including uniportal and biportal approaches, have been hindered by challenges such as steep learning curves and reliance on radiation-intensive C-arm guidance. We here describe the use of standard intraoperative navigation in UBE to reduce radiation exposure and increase surgical accuracy. A 24-year-old man with low back and bilateral leg pain with gait disturbance was referred to our hospital. He had had conservative treatment for 12 months in another hospital before admission, but this proved unsuccessful. On admission he had low back pain (VAS 4/10) and bilateral leg pain (VAS 8/10), muscle weakness of the bilateral legs (manual muscle testing (MMT) grade of the extensor hallucis longus: 4/4), and numbness of the bilateral lower legs. Preoperative lumbar MRI showed L4/5 large central disc herniation. He underwent C-arm free UBE discectomy under the guidance of O-arm navigation. The surgery was successful, with postoperative lumbar MRI showing good decompression of the dural sac and bilateral L5 nerve roots. The MMT grade and sensory function of both legs had recovered fully on final follow-up at one year. The new UBE technique under navigation guidance was shown to be useful for lumbar disc herniation. This innovative technique was safe and accurate for the treatment of lumbar intervertebral disc herniation, and minimized radiation exposure to surgeons. en-copyright= kn-copyright= en-aut-name=XiangHongfei en-aut-sei=Xiang en-aut-mei=Hongfei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=LatkaKajetan en-aut-sei=Latka en-aut-mei=Kajetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MastePraful en-aut-sei=Maste en-aut-mei=Praful kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumawatChetan en-aut-sei=Kumawat en-aut-mei=Chetan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyamotoAkiyoshi en-aut-sei=Miyamoto en-aut-mei=Akiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= en-keyword=lumbar disc herniation kn-keyword=lumbar disc herniation en-keyword=unilateral biportal endoscopic technique kn-keyword=unilateral biportal endoscopic technique en-keyword=navigation kn-keyword=navigation en-keyword=O-arm kn-keyword=O-arm en-keyword=minimally invasive spine surgery (MISS) kn-keyword=minimally invasive spine surgery (MISS) END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=469 end-page=474 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment of Tenosynovial Giant Cell Tumor of the Cervical Spine with Postoperative Anti-RANKL Antibody (Denosumab) Administration en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tenosynovial giant cell tumor (TGCT) is a fibrous histiocytic tumor originating in the synovial membrane. While cervical TGCT may not be considered a common diagnosis preoperatively because it is relatively rare, it has a high recurrence rate and should be considered. Total resection is preferable, but it can be challenging due to the risk of damaging the vertebral artery. Denosumab has shown effectiveness as a postoperative treatment for osteolytic bone lesion. Denosumab administration coupled with close follow-up might offer an effective postoperative treatment option for unresectable TGCT with bone invasion. en-copyright= kn-copyright= en-aut-name=HirataYuichi en-aut-sei=Hirata en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NagaseTakayuki en-aut-sei=Nagase en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AyadaYoshiyuki en-aut-sei=Ayada en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyakeHayato en-aut-sei=Miyake en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugaharaChiaki en-aut-sei=Sugahara en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoHidetaka en-aut-sei=Yamamoto en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OdaYoshinao en-aut-sei=Oda en-aut-mei=Yoshinao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Anatomic Pathology, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=tenosynovial giant cell tumor kn-keyword=tenosynovial giant cell tumor en-keyword=bone tumor kn-keyword=bone tumor en-keyword=spine kn-keyword=spine END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=453 end-page=458 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Case of Radiation-Induced Angiosarcoma after Breast-Conserving Surgery with Hypofractionated Radiotherapy in a Japanese Patient en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radiation-induced angiosarcoma (RIAS) is a rare, late adverse event of radiotherapy comprising approximately half of all radiation-induced sarcomas.

This study presents a case of RIAS that developed 5 years and 11 months after the completion of hypofractionated radiotherapy (42.56 Gy/16 fractions) following partial mastectomy. The patient was diagnosed with RIAS 10 months after the onset of skin redness. She underwent skin tumor resection, followed by paclitaxel, then pazopanib administration, but no radiotherapy. At 6 years and 2 months after surgery, no RIAS recurrence has been detected. en-copyright= kn-copyright= en-aut-name=KawataYujiro en-aut-sei=Kawata en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeKenta en-aut-sei=Watanabe en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TokiyaRyoji en-aut-sei=Tokiya en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsunoTakeshi en-aut-sei=Matsuno en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaRyo en-aut-sei=Tanaka en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TairaNaruto en-aut-sei=Taira en-aut-mei=Naruto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KatsuiKuniaki en-aut-sei=Katsui en-aut-mei=Kuniaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Pathology, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Dermatology, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Breast and Thyroid Surgery, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of Radiology, Kawasaki Medical School kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=hypofractionated radiotherapy kn-keyword=hypofractionated radiotherapy en-keyword=radiation-induced angiosarcoma kn-keyword=radiation-induced angiosarcoma END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=449 end-page=452 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Closure of Ventricular Septal Rupture through a Left Thoracotomy in a Patient with a History of Esophageal Reconstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 73-year-old man who had undergone esophagectomy and retrosternal gastric tube reconstruction for esophageal cancer 8 years prior was transferred to our hospital for the treatment of an acute myocardial infarction.

Seventeen days after admission, the rupture was successfully treated with a double-patch closure via a left anterolateral thoracotomy to avoid a surgical injury to his retrosternal gastric tube. Determining the best surgical approach to the heart is important for safe cardiac surgery in patients after esophageal reconstruction. en-copyright= kn-copyright= en-aut-name=KatoGentaro en-aut-sei=Kato en-aut-mei=Gentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OgawaTatsuya en-aut-sei=Ogawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayashidaTomohiro en-aut-sei=Hayashida en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimizuShuji en-aut-sei=Shimizu en-aut-mei=Shuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoShu en-aut-sei=Yamamoto en-aut-mei=Shu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShichijoTakeshi en-aut-sei=Shichijo en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Cardiovascular Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=2 en-affil=Department of Cardiovascular Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Cardiovascular Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=4 en-affil=Department of Cardiovascular Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences and Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Cardiovascular Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=6 en-affil=Department of Cardiovascular Surgery, Kagawa Prefectural Central Hospital kn-affil= en-keyword=acute myocardial infarction kn-keyword=acute myocardial infarction en-keyword=ventricular septal rupture kn-keyword=ventricular septal rupture en-keyword=retrosternal gastric tube reconstruction kn-keyword=retrosternal gastric tube reconstruction en-keyword=esophageal cancer kn-keyword=esophageal cancer en-keyword=left anterolateral thoracotomy kn-keyword=left anterolateral thoracotomy END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=439 end-page=447 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Risk Factors for Gangrenous Cholecystitis and the Outcomes of Early Cholecystectomy: A Retrospective Study of a Single-Center City General Hospital en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gangrenous cholecystitis (GC) is classified as moderate acute cholecystitis according to the Tokyo Guidelines from 2018 (TG18). We evaluated the risk factors for GC and the outcomes of early cholecystectomy. A total of 136 patients who underwent emergency cholecystectomy for acute cholecystitis were retrospectively analyzed; 58 of these patients (42.6%) were diagnosed with GC (GC group) based on our retrospective pathologic diagnosis. We comparatively evaluated the patient backgrounds and surgical outcomes between the GC group and non-GC group. The GC group was significantly older and included more hypertensive patients than the non-GC group. The GC group was prescribed more antibiotics as initial treatment than the non-GC group, and they had more days between onset and surgery. The preoperative white blood cell count and C-reactive protein values were significantly higher in the GC group than in the non-GC group, and these values were predictive factors for GC. Cholecystectomy required a longer operation time and caused greater blood loss in the GC group. The GC group also had longer hospitalization times than the non-GC group; however, no significant differences were observed in terms of postoperative complications. In conclusion, gangrenous changes should be assessed when diagnosing cholecystitis, and appropriate treatment, such as surgery or drainage, should be undertaken. en-copyright= kn-copyright= en-aut-name=YamashitaMampei en-aut-sei=Yamashita en-aut-mei=Mampei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakayuki en-aut-sei=Tanaka en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SumidaYorihisa en-aut-sei=Sumida en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiShoto en-aut-sei=Yamazaki en-aut-mei=Shoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaraYuki en-aut-sei=Hara en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FukudaAkiko en-aut-sei=Fukuda en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HisanagaMakoto en-aut-sei=Hisanaga en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WakataKoki en-aut-sei=Wakata en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ArakiMasato en-aut-sei=Araki en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=EguchiSusumu en-aut-sei=Eguchi en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=2 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, Sasebo City General Hospital kn-affil= affil-num=10 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= en-keyword=gangrenous kn-keyword=gangrenous en-keyword=cholecystitis kn-keyword=cholecystitis en-keyword=acute cholecystitis kn-keyword=acute cholecystitis en-keyword=laparoscopic cholecystectomy kn-keyword=laparoscopic cholecystectomy END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=6 article-no= start-page=429 end-page=437 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202412 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Partial versus Radical Nephrectomy for Small Renal Cancer: Comparative Propensity Score-Matching Analysis of Cardiovascular Event Risk en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although partial nephrectomy (PN) is preferred over radical nephrectomy (RN) for preserving renal function in patients with cT1 renal cancer, its impact on cardiovascular events (CVe) remains controversial. This study aimed to compare PN and RN in regard to the occurrence of CVe, including cerebrovascular events and exacerbation of hypertension (HT). We retrospectively analyzed 418 consecutive patients who underwent PN or RN for cT1 renal cancer. Propensity score-matching analysis was used to adjust for imbalances between patients who underwent PN and RN, leaving 102 patients in each group. The 5-year probability of cumulative CVe incidence was 6% in the PN group and 12% in the RN group (p=0.03), with a median follow-up of 73.5 months. The statistical significance was retained after propensity score matching for patients without preoperative proteinuria (p=0.03). For all CVe including cerebrovascular events and exacerbation of HT analyzed, PN provided a lower probability of occurrence than RN in patients with small renal cancers. en-copyright= kn-copyright= en-aut-name=KubotaRisa en-aut-sei=Kubota en-aut-mei=Risa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BekkuKensuke en-aut-sei=Bekku en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatayamaSatoshi en-aut-sei=Katayama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwataTakehiro en-aut-sei=Iwata en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraShingo en-aut-sei=Nishimura en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EdamuraKohei en-aut-sei=Edamura en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KobayashiTomoko en-aut-sei=Kobayashi en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KobayashiYasuyuki en-aut-sei=Kobayashi en-aut-mei=Yasuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ArakiMotoo en-aut-sei=Araki en-aut-mei=Motoo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Urology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chronic kidney disease kn-keyword=chronic kidney disease en-keyword=hypertension kn-keyword=hypertension en-keyword=nephrectomy kn-keyword=nephrectomy en-keyword=proteinuria kn-keyword=proteinuria END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=2 article-no= start-page=292 end-page=305 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241128 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The role of C1orf50 in breast cancer progression and prognosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the prognosis of breast cancer has significantly improved compared to other types of cancer, there are still some patients who expire due to recurrence or metastasis. Therefore, it is necessary to develop a method to identify patients with poor prognosis at the early stages of cancer. In the process of discovering new prognostic markers from genes of unknown function, we found that the expression of C1orf50 determines the prognosis of breast cancer patients, especially for those with Luminal A breast cancer. This study aims to elucidate the molecular role of C1orf50 in breast cancer progression. Bioinformatic analyses of the breast cancer dataset of TCGA, and in vitro analyses, reveal the molecular pathways influenced by C1orf50 expression. C1orf50 knockdown suppressed the cell cycle of breast cancer cells and weakened their ability to maintain the undifferentiated state and self-renewal capacity. Interestingly, upregulation of C1orf50 increased sensitivity to CDK4/6 inhibition. In addition, C1orf50 was found to be more abundant in breast cancer cells than in normal breast epithelium, suggesting C1orf50’s involvement in breast cancer pathogenesis. Furthermore, the mRNA expression level of C1orf50 was positively correlated with the expression of PD-L1 and its related factors. These results suggest that C1orf50 promotes breast cancer progression through cell cycle upregulation, maintenance of cancer stemness, and immune evasion mechanisms. Our study uncovers the biological functions of C1orf50 in Luminal breast cancer progression, a finding not previously reported in any type of cancer. en-copyright= kn-copyright= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAtsushi en-aut-sei=Tanaka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaekawaMasaki en-aut-sei=Maekawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=PeñaTirso en-aut-sei=Peña en-aut-mei=Tirso kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RogachevskayaAnna en-aut-sei=Rogachevskaya en-aut-mei=Anna kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AndoTeruhiko en-aut-sei=Ando en-aut-mei=Teruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItanoTakuto en-aut-sei=Itano en-aut-mei=Takuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatayamaHaruyoshi en-aut-sei=Katayama en-aut-mei=Haruyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DoiharaHiroyoshi en-aut-sei=Doihara en-aut-mei=Hiroyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=RoehrlMichael H. en-aut-sei=Roehrl en-aut-mei=Michael H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=2 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=3 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=4 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=5 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of General Surgery, Kawasaki Medical School General Medical Center kn-affil= affil-num=13 en-affil=Department of Pathology, Beth Israel Deaconess Medical Center, Boston, MA, USA Harvard Medical School kn-affil= affil-num=14 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=C1orf50 kn-keyword=C1orf50 en-keyword=Luminal A breast cancer kn-keyword=Luminal A breast cancer en-keyword=Cell cycle kn-keyword=Cell cycle en-keyword=Immune evasion kn-keyword=Immune evasion en-keyword=YAP/TAZ kn-keyword=YAP/TAZ END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=60 end-page=63 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful immunotherapy with ipilimumab and nivolumab in a patient with pulmonary sclerosing pneumocytoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulmonary sclerosing pneumocytoma (PSP) is a rare form of lung cancer that occasionally presents with lymph node and extrapulmonary metastases, and multiple lesions. The treatment of metastatic PSP remains undefined. This study reports the case of a 48-year-old female patient diagnosed with PSP following surgical intervention for a solitary nodule in the left lower lobe. Four years later, recurrence occurred in the left hilar and mediastinal lymph nodes, necessitating an additional resection. Concurrently, sacral metastases developed and required palliative radiotherapy. Genetic analysis identified an AKT1 E17K mutation, characteristic of PSP, and absence of programmed cell death ligand 1 (PD-L1) expression in the tumor. Two years post-recurrence, the tumor recurred in the left mammary gland and mediastinal lymph nodes. Combination immunotherapy with ipilimumab and nivolumab yielded a significantly positive response in this metastatic PSP case. This is the first reported case of successful treatment of multiple distant metastatic PSP with ipilimumab and nivolumab, following the failure of various local treatments. Further case series are warranted to validate the efficacy of immunotherapy in metastatic PSP. en-copyright= kn-copyright= en-aut-name=Inukai-MotokuraYumi en-aut-sei=Inukai-Motokura en-aut-mei=Yumi

kn-abstract=This study addresses the parallel stack loading problem, a general optimization problem arising in storage facilities such as container yards, slab yards, and warehouses. In this problem, we load incoming items into parallel stacks in the loading phase to minimize the number of relocations in the subsequent retrieval phase. Because of difficulties in treating the nested problem structure originating from the mutual dependence of the two phases, the existing studies approximately minimized the number of relocations using surrogate objective functions. In contrast, this study considers the parallel stack loading problem aiming to minimize the exact number of relocations. We first provide an integer programming formulation and next develop a nested branch-and-bound algorithm. In a computational study, we verify the effectiveness of the proposed branch-and-bound algorithm and evaluate the known surrogate objective functions based on the exact minimization. en-copyright= kn-copyright= en-aut-name=TanakaShunji en-aut-sei=Tanaka en-aut-mei=Shunji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ElWakilMohamed en-aut-sei=ElWakil en-aut-mei=Mohamed kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EltawilAmr en-aut-sei=Eltawil en-aut-mei=Amr kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Faculty of Environmental, Life and Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Department of Production Engineering and Mechanical Design, Faculty of Engineering, Tanta University kn-affil= affil-num=3 en-affil=Department of Industrial and Manufacturing Engineering, Egypt Japan University of Science and Technology kn-affil= en-keyword=Logistics kn-keyword=Logistics en-keyword=Parallel stack loading problem kn-keyword=Parallel stack loading problem en-keyword=Relocation kn-keyword=Relocation en-keyword=Integer programming kn-keyword=Integer programming en-keyword=Branch-and-bound algorithm kn-keyword=Branch-and-bound algorithm END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=11 article-no= start-page=e73775 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241115 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Axillary Reactive Lymphoid Hyperplasia, Likely Due to Unicentric Castleman Disease, and the Concurrent Presence of Orbital Mucosa-Associated Lymphoid Tissue (MALT) Lymphoma: A Six-Year Follow-Up Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Castleman disease is a lymphadenopathy of unknown cause at a single site, which is designated as unicentric Castleman disease, or at multiple sites designated as multicentric Castleman disease. We present a patient who showed axillary reactive lymphoid hyperplasia, likely due to unicentric Castleman disease, and orbital extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) lymphoma in a six-year follow-up. A 76-year-old man had a painless left axillary mass for an unknown period and also left complete blepharoptosis with no other systemic symptoms. Suspected of lymphoma, iliac bone marrow biopsy showed no anomalous cells, and positron emission tomography demonstrated abnormal uptake at the left axilla and in the left superior anterior orbit. Incisional biopsy of the left axillary mass demonstrated hyperplastic lymphoid follicles with an atrophic germinal center and prominent small vessels in the follicular center, indicative of unicentric Castleman disease. One year later, annual follow-up positron emission tomography disclosed a high uptake site, next to the previously-identified cyst, in the pancreatic body. Trans-gastric fine needle pancreatic biopsy proved adenocarcinoma and he underwent subtotal stomach-preserving pancreaticoduodenectomy with jejunal anastomosis. He was well for six months after the surgery and thus, underwent resection of the left orbital lesion at 78 years old. The pathology of the orbital lesion showed ambiguous nodular structure with massive infiltration with CD20-positive medium-sized lymphoid cells which were κ monotype in immunoglobulin light chain restriction, indicative of MALT lymphoma. In the four-year period of the COVID-19 pandemic, he was healthy and followed with no treatment until the age of 82 years when he underwent radiation (46 Gy) to the left axillary lesion which did not regress. He then underwent eyelid levator muscle plication for left blepharoptosis since the left orbital lesion remained unpalpable. The six-year follow-up showed that concurrent and independent orbital MALT lymphoma and axillary reactive lymphoid hyperplasia, likely due to unicentric Castleman disease, were both stable. The present case illustrates how important it is to make pathological diagnoses in different anatomical lesions after the initial diagnosis of Castleman disease. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiTomokazu en-aut-sei=Fuji en-aut-mei=Tomokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= en-keyword=blepharoptosis kn-keyword=blepharoptosis en-keyword=castleman disease kn-keyword=castleman disease en-keyword=extranodal marginal zone b-cell lymphoma of mucosa-associated lymphoid tissue (malt) lymphoma kn-keyword=extranodal marginal zone b-cell lymphoma of mucosa-associated lymphoid tissue (malt) lymphoma en-keyword=pancreatic cancer kn-keyword=pancreatic cancer en-keyword=radiation kn-keyword=radiation en-keyword=reactive lymphoid hyperplasia kn-keyword=reactive lymphoid hyperplasia END start-ver=1.4 cd-journal=joma no-vol=42 cd-vols= no-issue=1 article-no= start-page=1 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241021 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tectal glioma: clinical, radiological, and pathological features, and the importance of molecular analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tectal glioma (TG) is a rare lower grade glioma (LrGG) that occurs in the tectum, mainly affecting children. TG shares pathological similarities with pilocytic astrocytoma (PA), but recent genetic analyses have revealed distinct features, such as alterations in KRAS and BRAF. We conducted a retrospective review of cases clinically diagnosed as TG and treated at our institute between January 2005 and March 2023. Six cases were identified and the median age was 30.5 years. Four patients underwent biopsy and two patients underwent tumor resection. Histological diagnoses included three cases of PA, one case of astrocytoma, and two cases of high-grade glioma. The integrated diagnosis, according to the fifth edition of the World Health Organization Classification of Tumours of the central nervous system, included two cases of PA and one case each of diffuse high-grade glioma; diffuse midline glioma H3 K27-altered; glioblastoma; and circumscribed astrocytic glioma. Among the three patients who underwent molecular evaluation, two had KRAS mutation and one had H3-3A K27M mutation. Our results demonstrate the diverse histological and molecular characteristics of TG distinct from other LrGGs. Given the heterogeneous pathological background and the risk of pathological progression in TG, we emphasize the importance of comprehensive diagnosis, including molecular evaluation. en-copyright=

kn-abstract=Nesidioblastosis, also known as persistent hyperinsulinemic hypoglycemia, is usually observed in children and infants, although more recently adult-onset nesidioblastosis has also been described. We present a case of nesidioblastosis in a 78-year-old man that was detected by 111In-pentetreotide single photon emission computed tomography (SPECT/CT). The patient was transferred to our hospital’s emergency department in a hypoglycemic coma. Dynamic enhanced CT could detect no lesion in the pancreas, but an 111In-pentetreotide SPECT/CT scan performed after a similar episode four weeks later showed increased focal uptake at the head of the pancreas. The results of a selective arterial calcium injection test were negative. After careful consideration and discussion among colleagues, surgical intervention was selected, and a pancreaticoduodenectomy was performed. On histology, there were elevated numbers of Langerhans islets in the pancreatic head, and the islets themselves appeared enlarged. Hypertrophic β-cells comprised the majority, but α-cells, δ-cells and pancreatic polypeptide were also detected in the islets. Based on the histopathological results and repeated hyperinsulinemic hypoglycemic crises, the patient was finally diagnosed with adult-onset nesidioblastosis. He had no hypoglycemic symptoms during outpatient follow-up examination. Since 111In-pentetreotide SPECT/CT may be able to detect nesidioblastosis, clinicians should consider this relatively new-modality examination when encountering such cases. en-copyright= kn-copyright= en-aut-name=SakamotoShinya en-aut-sei=Sakamoto en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TabuchiMotoyasu en-aut-sei=Tabuchi en-aut-mei=Motoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YoshimatsuRika en-aut-sei=Yoshimatsu en-aut-mei=Rika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HishidaAi en-aut-sei=Hishida en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumotoManabu en-aut-sei=Matsumoto en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IwataJun en-aut-sei=Iwata en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkabayashiTakehiro en-aut-sei=Okabayashi en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gastroenteorlogical Surgery, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Department of Gastroenteorlogical Surgery, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Department of Radiology, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Endocrinology and Metabolism, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Department of Diagnostic Pathology, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Gastroenteorlogical Surgery, Kochi Health Sciences Center kn-affil= en-keyword=111In-pentetreotide kn-keyword=111In-pentetreotide en-keyword=nesidioblastosis kn-keyword=nesidioblastosis en-keyword=single-photon emission computed tomography kn-keyword=single-photon emission computed tomography en-keyword=hyperinsulinemic hypoglycemia kn-keyword=hyperinsulinemic hypoglycemia END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=401 end-page=405 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pediatric Severe Febrile Thrombocytopenia Syndrome: A Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Severe febrile thrombocytopenia syndrome (SFTS) is a tick-borne infectious disease that is endemic in parts of eastern Asia. Few pediatric cases have been reported. We describe a case of SFTS in a seven-year-old girl who presented with prolonged fever and gastrointestinal symptoms. Leukopenia and thrombocytopenia on hematology, and a history of outdoor activity led us to diagnose SFTS, although the patient had no tick bite marks. We also review the literature and discuss the characteristics of pediatric SFTS. Physicians should consider SFTS in the differential diagnosis of fever with thrombocytopenia in children living in endemic areas. en-copyright= kn-copyright= en-aut-name=ToyotaYusuke en-aut-sei=Toyota en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=UdaKazuhiro en-aut-sei=Uda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShirabeKomei en-aut-sei=Shirabe en-aut-mei=Komei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Pediatrics, NHO Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of Pediatrics, NHO Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Yamaguchi Prefectural Institute of Public Health and Environment kn-affil= affil-num=4 en-affil=Department of Pediatrics, NHO Iwakuni Clinical Center kn-affil= en-keyword=child kn-keyword=child en-keyword=tick-borne disease kn-keyword=tick-borne disease en-keyword=severe febrile thrombocytopenia syndrome kn-keyword=severe febrile thrombocytopenia syndrome en-keyword=zoonoses kn-keyword=zoonoses END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=387 end-page=399 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Radon Inhalation on Murine Brain Proteins: Investigation Using Proteomic and Multivariate Analyses en-subtitle= kn-subtitle= en-abstract= kn-abstract=Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required. Although several studies have used proteomics to investigate the effects of radon inhalation on body proteins, none has focused on brain proteins. In this study, we evaluated the expression status of proteins in murine brains using proteomic and multivariate analyses to identify those whose expressions changed following two days of radon inhalation at a concentration of 1,500 Bq/m3. We found associations of radon inhalation with the expressions of seven proteins related to neurotransmission and heat shock. These proteins may be proposed as biomarkers indicative of radon inhalation. Although further studies are required to obtain the detailed biological significance of these protein alterations, this study contributes to the elucidation of the biological effects of radon inhalation as a low-dose radiation. en-copyright= kn-copyright= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanzakiNorie en-aut-sei=Kanzaki en-aut-mei=Norie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakenakaReiju en-aut-sei=Takenaka en-aut-mei=Reiju kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SakodaAkihiro en-aut-sei=Sakoda en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyajiTakaaki en-aut-sei=Miyaji en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=3 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=4 en-affil=Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil=Ningyo-toge Environmental Engineering Center, Japan Atomic Energy Agency kn-affil= affil-num=6 en-affil=Advanced Science Research Center, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Health Sciences, Okayama University kn-affil= affil-num=8 en-affil=Faculty of Health Sciences, Okayama University kn-affil= en-keyword=radon inhalation kn-keyword=radon inhalation en-keyword=proteomics kn-keyword=proteomics en-keyword=multivariate analysis kn-keyword=multivariate analysis en-keyword=brain kn-keyword=brain en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=5 article-no= start-page=363 end-page=370 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202410 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Small-for-Gestational-Age Status and the Risk of Kawasaki Disease: A Nationwide Birth Cohort in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Kawasaki disease (KD) is a pediatric disease of unknown etiology that commonly affects infants in East Asia. Infants born small for gestational age (SGA) have weaker immune systems and are more susceptible to infection. Using data from a nationwide Japanese birth cohort study conducted in 2010 (n=34,579), we investigated whether SGA increases the risk of KD. SGA was defined as birth weight below the 10th percentile for gestational age. The outcome was hospitalization for KD between 6 and 30 months of age. The association between SGA and hospitalization for KD, adjusted for child and maternal factors, was examined using logistic regression. Of the 231 children hospitalized for KD, 9.5% were SGA. Further statistical analysis showed that SGA did not increase the odds ratio (OR) of hospitalization for KD (adjusted OR 1.12, 95% confidence interval 0.71-1.75). This result was not changed with stratification by early daycare attendance and preterm status. Reasons for the lack of association may include the multifactorial pathogenesis of KD; in addition, the types of infections to which SGA infants are predisposed may differ from those triggering KD. Overall, our large nationwide study found no association between SGA and KD. en-copyright= kn-copyright= en-aut-name=TakanagaSatoe en-aut-sei=Takanaga en-aut-mei=Satoe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KadowakiTomoka en-aut-sei=Kadowaki en-aut-mei=Tomoka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Kawasaki disease (KD) kn-keyword=Kawasaki disease (KD) en-keyword=small for gestational age (SGA) kn-keyword=small for gestational age (SGA) en-keyword=cohort kn-keyword=cohort en-keyword=epidemiology kn-keyword=epidemiology END start-ver=1.4 cd-journal=joma no-vol=18 cd-vols= no-issue=1 article-no= start-page=19 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240929 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Assessment of the renal function of patients with anorexia nervosa en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background A decreased glomerular filtration rate (GFR), estimated using creatinine (Cr- eGFR), is often found at the initial presentation of anorexia nervosa (AN). Its pathophysiology has been explained mainly by dehydration, and chronic hypokalemia is also thought to be a cause. However, because we have often experienced cases of AN with decreased Cr-eGFR without these conditions, we must consider different etiologies. The focus of this paper is on low free triiodothyronine (FT3) syndrome. We also discuss the utility of eGFR, estimated using cystatin-C (CysC-eGFR), for these patients.
Methods The data of 39 patients diagnosed with AN between January 2005 and December 2023 was available for study. The characteristics of patients at the lowest and highest body mass index standard deviation score (BMI-SDS) were examined. Data on the parameters Cr-eGFR, CysC-eGFR, dehydration markers, potassium (K), and hormonal data and BMI-SDS were assessed during the treatment course to evaluate the correlations in these parameters. Blood hematocrit, uric acid (UA), blood urine nitrogen (BUN) level, and urine specific gravity were adopted as dehydration markers; FT3, free thyroxine, thyroid stimulating hormone, and insulin-like growth factor were adopted as hormonal data. Cr-eGFR and simultaneously evaluated dehydration markers, K, or hormonal data were extracted and correlations associated with the changes in BMI-SDS were examined. Furthermore, Cr-eGFR and simultaneously assessed CysC-eGFR were compared.
Results When the BMI-SDS was at the lowest value, low-FT3 syndrome was shown. Severe hypokalemia was not found in our study. A linear relation was not found between Cr-eGFR and BMI-SDS. A statistically significant correlation was found between Cr-eGFR and FT3 (p = 0.0025). Among the dehydration markers, statistically significant correlations were found between Cr-eGFR and BUN or UA. The difference between Cr-eGFR and CysC-eGFR was prominent, and CysC-eGFR showed much higher values.
Conclusions Our data indicates that low-FT3 syndrome and dehydration were related to the renal function of our patients with AN. Furthermore, our data suggest that caution is needed in the interpretation of kidney function evaluation when using CysC-eGFR in cases of AN. en-copyright= kn-copyright= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShigeyasuYoshie en-aut-sei=Shigeyasu en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ManaHanzawa en-aut-sei=Mana en-aut-mei=Hanzawa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Clinical Pediatrics, Okayama University Academic Field of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=6 en-affil=Clinical Psychology Section, Department of Medical Support, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Anorexia nervosa kn-keyword=Anorexia nervosa en-keyword=Dehydration kn-keyword=Dehydration en-keyword=Glomerular filtration rate estimated using creatinine kn-keyword=Glomerular filtration rate estimated using creatinine en-keyword=Glomerular filtration rate estimated using cystatin-C kn-keyword=Glomerular filtration rate estimated using cystatin-C en-keyword=Hypokalemia kn-keyword=Hypokalemia en-keyword=Low free triiodothyronine syndrome kn-keyword=Low free triiodothyronine syndrome END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=10 article-no= start-page=e70865 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20241004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Presumed Choroidopathy of IgG4-Related Disease Discovered During 16-Year Follow-Up of a Patient With Polycystic Kidney Disease en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immunoglobulin G4 (IgG4)-related disease is characterized by infiltration with IgG4-producing plasma cells in different organs and the elevation of serum IgG4. We present a patient with polycystic kidney disease in long-term follow-up who developed bilateral lacrimal gland enlargement and presumed IgG4-related choroidopathy at different time points. A 45-year-old woman developed bilateral upper eyelid swelling. Head MRI showed bilateral lacrimal gland enlargement, and the resection on both sides revealed foci of infiltration with lymphocytes and plasma cells in bilateral lacrimal glands. The IgG4-immunostaining did not satisfy the diagnostic criteria. She had been taking oral valsartan 40 mg daily for hypertension with polycystic kidney disease.

The patient was well until the age of 49 years, when she noticed yellowish vision in the right eye compared to the left eye. The right eye showed multiple yellowish spotty lesions in the deep retina to choroid with a mildly hyperemic optic disc, while the left eye showed the normal fundus. No inflammation was noted in the anterior segments of both eyes. Fundus angiography demonstrated early-phase no-filling with late-phase leakage by fluorescein dye and both early-phase and late-phase no-filling by indocyanine green dye, leading to the diagnosis of acute posterior multifocal placoid pigment epitheliopathy (APMPPE). She began to have oral prednisolone tapered from 30 mg daily and discontinued in a year. At the age of 52 years, she switched to candesartan 8 mg daily and began to have tolvaptan (a selective competitive vasopressin receptor 2 (V2) antagonist) 90 mg daily for polycystic kidney disease with liver cysts. At that time, the lesions in the right eye had mild degeneration.

The patient was followed once a year ophthalmologically to maintain good vision. At 57 years, serum IgG4, which was measured for the first time on suspicion of IgG4-related disease, was elevated to 269.6 mg/dL. In the following four years to the latest visit at 61 years, she kept stable but high levels of serum IgG4 around 300 mg/dL. Serum IgG4 measurement is helpful to make a clinical diagnosis and, hence, a clinical decision since the spectrum of IgG4-related disease remains obscure. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TsujiKenji en-aut-sei=Tsuji en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Ophthalmology, Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Pathology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Nephrology, Okayama University Hospital kn-affil= en-keyword=acute posterior multifocal placoid pigment epitheliopathy kn-keyword=acute posterior multifocal placoid pigment epitheliopathy en-keyword=choroidopathy kn-keyword=choroidopathy en-keyword=uveitis kn-keyword=uveitis en-keyword=lacrimal gland tumor kn-keyword=lacrimal gland tumor en-keyword=igg4-related disease kn-keyword=igg4-related disease END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=1099 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Histological differences related to autophagy in the minor salivary gland between primary and secondary types of Sjögren's syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Some forms of Sjögren’s syndrome (SS) follow a clinical course accompanied by systemic symptoms caused by lymphocyte infiltration and proliferation in the liver, kidneys, and other organs. To better understand the clinical outcomes of SS, here we used minor salivary gland tissues from patients and examine their molecular, biological, and pathological characteristics. A retrospective study was performed, combining clinical data and formalin-fixed paraffin-embedded (FFPE) samples from female patients over 60 years of age who underwent biopsies at Okayama University Hospital. We employed direct digital RNA counting with nCounter® and multiplex immunofluorescence analysis with a PhenoCycler™ on the labial gland biopsies. We compared FFPE samples from SS patients who presented with other connective tissue diseases (secondary SS) with those from stable SS patients with symptoms restricted to the exocrine glands (primary SS). Secondary SS tissues showed enhanced epithelial damage and lymphocytic infiltration accompanied by elevated expression of autophagy marker genes in the immune cells of the labial glands. The close intercellular distance between helper T cells and B cells positive for autophagy-associated molecules suggests accelerated autophagy in these lymphocytes and potential B cell activation by helper T cells. These findings indicate that examination of FFPE samples from labial gland biopsies can be an effective tool for evaluating molecular histological differences between secondary and primary SS through multiplexed analysis of gene expression and tissue imaging. en-copyright= kn-copyright= en-aut-name=Ono-MinagiHitomi en-aut-sei=Ono-Minagi en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NohnoTsutomu en-aut-sei=Nohno en-aut-mei=Tsutomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KatsuyamaTakayuki en-aut-sei=Katsuyama en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyawakiKohta en-aut-sei=Miyawaki en-aut-mei=Kohta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=IbaragiSoichiro en-aut-sei=Ibaragi en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IidaSeiji en-aut-sei=Iida en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SakaiTakayoshi en-aut-sei=Sakai en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OhuchiHideyo en-aut-sei=Ohuchi en-aut-mei=Hideyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Cytology and Histology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Cytology and Histology, Okayama University Medical School kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Pathology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Hospital kn-affil= affil-num=6 en-affil=Division of Precision Medicine, Kyushu University School of Medicine kn-affil= affil-num=7 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral and Maxillofacial Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Reconstructive Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Pathology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=12 en-affil=Department of Rehabilitation for Orofacial Disorders, Osaka University Graduate School of Dentistry kn-affil= affil-num=13 en-affil=Department of Cytology and Histology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Autoimmune disease kn-keyword=Autoimmune disease en-keyword=Xerostomia kn-keyword=Xerostomia en-keyword=Multiplex immunostaining kn-keyword=Multiplex immunostaining en-keyword=Spatial analysis kn-keyword=Spatial analysis en-keyword=Autophagy kn-keyword=Autophagy END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=16 article-no= start-page=4108 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240819 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Scaffold Geometrical Structure on Macrophage Polarization during Bone Regeneration Using Honeycomb Tricalcium Phosphate en-subtitle= kn-subtitle= en-abstract= kn-abstract=The polarization balance of M1/M2 macrophages with different functions is important in osteogenesis and bone repair processes. In a previous study, we succeeded in developing honeycomb tricalcium phosphate (TCP), which is a cylindrical scaffold with a honeycomb arrangement of straight pores, and we demonstrated that TCP with 300 and 500 mu m pore diameters (300TCP and 500TCP) induced bone formation within the pores. However, the details of the influence of macrophage polarization on bone formation using engineered biomaterials, especially with respect to the geometric structure of the artificial biomaterials, are unknown. In this study, we examined whether differences in bone tissue formation due to differences in TCP geometry were due to the polarity of the assembling macrophages. Immunohistochemistry for IBA-1, iNOS, and CD163 single staining was performed. The 300TCP showed a marked infiltration of iNOS-positive cells, which are thought to be M1 macrophages, during the osteogenesis process, while no involvement of CD163-positive cells, which are thought to be M2 macrophages, was observed in the TCP pores. In addition, 500TCP showed a clustering of iNOS-positive cells and CD163-positive cells at 2 weeks, suggesting the involvement of M2 macrophages in the formation of bone tissue in the TCP pores. In conclusion, we demonstrated for the first time that the geometrical structure of the artificial biomaterial, i.e., the pore size of honeycomb TCP, affects the polarization of M1/2 macrophages and bone tissue formation in TCP pores. en-copyright= kn-copyright= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujigiwaHidetsugu en-aut-sei=Tsujigiwa en-aut-mei=Hidetsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ChangAnqi en-aut-sei=Chang en-aut-mei=Anqi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PiaoTianyan en-aut-sei=Piao en-aut-mei=Tianyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InadaYasunori en-aut-sei=Inada en-aut-mei=Yasunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ArashimaTakuma en-aut-sei=Arashima en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MorimatsuAyumi en-aut-sei=Morimatsu en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Life Science, Faculty of Science, Okayama University of Science kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=11 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=honeycomb TCP kn-keyword=honeycomb TCP en-keyword=bone formation kn-keyword=bone formation en-keyword=macrophages kn-keyword=macrophages en-keyword=polarization kn-keyword=polarization END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=14543 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240624 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cervical spinal cord stimulation exerts anti-epileptic effects in a rat model of epileptic seizure through the suppression of CCL2-mediated cascades en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epidural spinal cord stimulation (SCS) is indicated for the treatment of intractable pain and is widely used in clinical practice. In previous basic research, the therapeutic effects of SCS have been demonstrated for epileptic seizure. However, the mechanism has not yet been elucidated. In this study, we investigated the therapeutic effect of SCS and the influence of epileptic seizure. First, SCS in the cervical spine was performed. The rats were divided into four groups: control group and treatment groups with SCS conducted at 2, 50, and 300 Hz frequency. Two days later, convulsions were induced by the intraperitoneal administration of kainic acid, followed by video monitoring to assess seizures. We also evaluated glial cells in the hippocampus by fluorescent immunostaining, electroencephalogram measurements, and inflammatory cytokines such as C-C motif chemokine ligand 2 (CCL2) by quantitative real-time polymerase chain reaction. Seizure frequency and the number of glial cells were significantly lower in the 300 Hz group than in the control group. SCS at 300 Hz decreased gene expression level of CCL2, which induces monocyte migration. SCS has anti-seizure effects by inhibiting CCL2-mediated cascades. The suppression of CCL2 and glial cells may be associated with the suppression of epileptic seizure. en-copyright= kn-copyright= en-aut-name=OkazakiYosuke en-aut-sei=Okazaki en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SasakiTatsuya en-aut-sei=Sasaki en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HosomotoKakeru en-aut-sei=Hosomoto en-aut-mei=Kakeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanimotoShun en-aut-sei=Tanimoto en-aut-mei=Shun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawaiKoji en-aut-sei=Kawai en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NagaseTakayuki en-aut-sei=Nagase en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugaharaChiaki en-aut-sei=Sugahara en-aut-mei=Chiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YabunoSatoru en-aut-sei=Yabuno en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KinKyohei en-aut-sei=Kin en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SasadaSusumu en-aut-sei=Sasada en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YasuharaTakao en-aut-sei=Yasuhara en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurosurgery, Kure Kyosai Hospital kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Neurosurgery, Okayama Rosai Hospital kn-affil= en-keyword=Epileptic seizure kn-keyword=Epileptic seizure en-keyword=Glial cells kn-keyword=Glial cells en-keyword=Spinal cord stimulation kn-keyword=Spinal cord stimulation en-keyword=C-C motif chemokine ligand 2 kn-keyword=C-C motif chemokine ligand 2 END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=5 article-no= start-page=897 end-page=900 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A randomized, open-label phase II study on the preventive effect of goshajinkigan against peripheral neuropathy induced by paclitaxel-containing chemotherapy: The OLCSG2101 study protocol en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Paclitaxel (PTX) is an essential cytotoxic anticancer agent and a standard treatment regimen component for various malignant tumors, including advanced unresectable non-small cell lung cancer, thymic cancer, and primary unknown cancers. However, chemotherapy-induced peripheral neuropathy (CIPN) caused by PTX is a significant adverse event that may lead to chemotherapy discontinuation and deterioration of the quality of life (QOL). Although treatment modalities such as goshajinkigan (GJG), pregabalin, and duloxetine are empirically utilized for CIPN, there is no established evidence for an agent as a preventive measure. We designed a randomized phase II trial (OLCSG2101) to investigate whether prophylactic GJG administration can prevent the onset of CIPN induced by PTX.
Methods: This study was designed as a two-arm, prospective, randomized, multicenter phase II trial. The patients will be randomly assigned to either the GJG prophylaxis arm (Arm A) or the GJG non-prophylaxis arm (Arm B), using cancer type (lung cancer or not) and age (<70 years or not) as adjustment factors. A total of 66 patients (33 in each arm) will be enrolled.
Discussion: The results of this study may contribute to better management of CIPN, which can enable the continuation of chemotherapy and maintenance of the patient's QOL.
Ethics and dissemination: Ethical approval was obtained from the certified review board of Okayama University (approval no. CRB21-005) on September 28, 2021. Results will be published in peer-reviewed journals and presented at national and international conferences.

(MRI) findings for a subglottic pleomorphic adenoma. Here, we describe the case of a 62-year-old man with a subglottic pleomorphic adenoma. Endoscopic findings revealed a smooth-surfaced tumor arising from the subglottic posterior wall. MRI revealed the lesion as an isointense region on T1-weighted images, which was homogeneously enhanced. This lesion showed a heterogeneously hyperintense region on T2-weighted images. Diffusion-weighted imaging (DWI) showed slightly high intensity in the same area, with a normal or only slightly high apparent diffusion coefficient (ADC). Laryngomicrosurgery was performed for transoral excision of the subglottic tumor, resulting in a postsurgical diagnosis of pleomorphic adenoma. en-copyright= kn-copyright= en-aut-name=FurukawaChieko en-aut-sei=Furukawa en-aut-mei=Chieko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TachibanaTomoyasu en-aut-sei=Tachibana en-aut-mei=Tomoyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NobuhisaTetsuji en-aut-sei=Nobuhisa en-aut-mei=Tetsuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KanieYuichiro en-aut-sei=Kanie en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WaniYoji en-aut-sei=Wani en-aut-mei=Yoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumotoJun-Ya en-aut-sei=Matsumoto en-aut-mei=Jun-Ya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KariyaAkifumi en-aut-sei=Kariya en-aut-mei=Akifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatoAsuka en-aut-sei=Sato en-aut-mei=Asuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=IshikawaIichiro en-aut-sei=Ishikawa en-aut-mei=Iichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NaoiYuto en-aut-sei=Naoi en-aut-mei=Yuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AndoMizuo en-aut-sei=Ando en-aut-mei=Mizuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Otolaryngology Head and Neck Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=2 en-affil=Department of Otolaryngology Head and Neck Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=3 en-affil=Department of Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=6 en-affil=Department of Otolaryngology Head and Neck Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=7 en-affil=Department of Otolaryngology Head and Neck Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=8 en-affil=Department of Otolaryngology Head and Neck Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=9 en-affil=Department of Surgery, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=10 en-affil=Department of Otolaryngology Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Otolaryngology Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=subglottis kn-keyword=subglottis en-keyword=pleomorphic adenoma kn-keyword=pleomorphic adenoma en-keyword=MRI kn-keyword=MRI en-keyword=transoral surgery kn-keyword=transoral surgery END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=4 article-no= start-page=323 end-page=330 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Recipient Age on Perioperative Complications after Pediatric Liver Transplantation: A Single-Center Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=It has not been clear how recipient age affects the incidence of serious complications after pediatric living donor liver transplantation (LDLT). We investigated the records of 42 pediatric patients receiving LDLT, dividing our sample into two groups: the infant group (aged < 1 year) and the non-infant group (aged ≥ 1 year and ≤15 years). The primary outcome was postoperative complications assessed using the Clavien-Dindo classification. Multivariate analysis using the Cox regression model was applied to adjust for confounding factors in assessing the incidence of Clavien-Dindo grade ≥ III (C-D ≥ III) complications. The incidence of C-D ≥ III complications was higher in the non-infant group (46.2%) than in the infant group (12.5%) (odds ratio 6.00, 95% confidence interval [CI] 1.13-31.88, p=0.03). In multivariate analysis using the Cox regression model, the Graft-to-Recipient Weight Ratio (GRWR) was independently associated with the incidence of C-D ≥ III complications (hazard ratio [HR] 0.62, 95%CI 0.40-0.95, p=0.03), but being an infant was not (HR 0.84, 95%CI 0.35-1.98, p=0.68). In conclusion, the incidence of C-D ≥ III complications was higher in the non-infant group than in the infant group, but this was largely a function of GRWR: multivariate analysis revealed that GRWR was independently associated with complications. en-copyright= kn-copyright= en-aut-name=KatayamaAkira en-aut-sei=Katayama en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimuraSatoshi en-aut-sei=Kimura en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MatsusakiTakashi en-aut-sei=Matsusaki en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesia, Kyoto University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology, Mie University Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=pediatric liver transplantation kn-keyword=pediatric liver transplantation en-keyword=postoperative severe complications kn-keyword=postoperative severe complications en-keyword=Graft-to-Recipient Weight Ratio kn-keyword=Graft-to-Recipient Weight Ratio END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=17591 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240730 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Training high-performance deep learning classifier for diagnosis in oral cytology using diverse annotations en-subtitle= kn-subtitle= en-abstract= kn-abstract=The uncertainty of true labels in medical images hinders diagnosis owing to the variability across professionals when applying deep learning models. We used deep learning to obtain an optimal convolutional neural network (CNN) by adequately annotating data for oral exfoliative cytology considering labels from multiple oral pathologists. Six whole-slide images were processed using QuPath for segmenting them into tiles. The images were labeled by three oral pathologists, resulting in 14,535 images with the corresponding pathologists' annotations. Data from three pathologists who provided the same diagnosis were labeled as ground truth (GT) and used for testing. We investigated six models trained using the annotations of (1) pathologist A, (2) pathologist B, (3) pathologist C, (4) GT, (5) majority voting, and (6) a probabilistic model. We divided the test by cross-validation per slide dataset and examined the classification performance of the CNN with a ResNet50 baseline. Statistical evaluation was performed repeatedly and independently using every slide 10 times as test data. For the area under the curve, three cases showed the highest values (0.861, 0.955, and 0.991) for the probabilistic model. Regarding accuracy, two cases showed the highest values (0.988 and 0.967). For the models using the pathologists and GT annotations, many slides showed very low accuracy and large variations across tests. Hence, the classifier trained with probabilistic labels provided the optimal CNN for oral exfoliative cytology considering diagnoses from multiple pathologists. These results may lead to trusted medical artificial intelligence solutions that reflect diverse diagnoses of various professionals. en-copyright= kn-copyright= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaFuta en-aut-sei=Tanaka en-aut-mei=Futa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HaraTakeshi en-aut-sei=Hara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OchiaiTakanaga en-aut-sei=Ochiai en-aut-mei=Takanaga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ShimadaKatsumitsu en-aut-sei=Shimada en-aut-mei=Katsumitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InoueYuta en-aut-sei=Inoue en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakiYoshihiro en-aut-sei=Taki en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaiFumi en-aut-sei=Nakai en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakaiYasuhiro en-aut-sei=Nakai en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=IshihamaTakanori en-aut-sei=Ishihama en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyazakiRyo en-aut-sei=Miyazaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MurakamiSatoshi en-aut-sei=Murakami en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MiyakeMinoru en-aut-sei=Miyake en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=3 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=5 en-affil=Division of Oral Pathogenesis and Disease Control, Department of Oral Pathology, Asahi University School of Dentistry kn-affil= affil-num=6 en-affil=Department of Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=7 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=8 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=9 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=10 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=12 en-affil=Stony Brook Cancer Center, Stony Brook University kn-affil= affil-num=13 en-affil=Department of Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=14 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=15 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= en-keyword=Deep learning kn-keyword=Deep learning en-keyword=Oral cytology kn-keyword=Oral cytology en-keyword=Classification kn-keyword=Classification en-keyword=Convolutional neural network kn-keyword=Convolutional neural network en-keyword=Probabilistic labeling kn-keyword=Probabilistic labeling END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=341 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240813 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pathological findings in enucleated eyes of patients with neurofibromatosis type 1: report of a case with 15-year follow-up and review of 14 patients in the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Backgrounds Iris nodules are frequently noted as clinical manifestations of neurofibromatosis type 1 but the other intraocular manifestations are rare.

He had undergone four-time preceding surgeries for eyelid and orbital mass reduction on the left side in childhood and had developed total retinal detachment 10 years previously. Pathologically, the enucleated eye showed massive retinal gliosis positive for both S-100 and glial fibrillary acidic protein (GFAP) in the area with involvement of the detached retinal neuronal layer, together with a more fibrotic lesion along the choroid which were, in contrast, negative for both S-100 and GFAP. The choroid, ciliary body, and iris did not show apparent neurofibroma while episcleral neurofibroma was present.
Literature review In review of enucleated eyes of 14 patients in the literature, buphthalmic eyes with early-onset glaucoma on the unilateral side was clinically diagnosed in 9 patients who frequently showed varying extent of hemifacial neurofibromatosis which involved the eyelid and orbit on the same side. Pathologically, neurofibromas in varying extent were found in the choroid of 12 patients. One patient showed choroidal malignant melanoma on the left side and fusiform enlargement of the optic nerve on the right side suspected of optic nerve glioma. The phthisic eye in another patient showed massive retinal gliosis similar to the present patient.
Conclusions In summary of the 15 patients with neurofibromatosis type 1, including the present patient, buphthalmic or phthisic eyes with no vision were enucleated for cosmetic reasons and showed choroidal neurofibroma in most patients and massive retinal gliosis in two patients including the present patient. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SenoTakaya en-aut-sei=Seno en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamadaKiyoshi en-aut-sei=Yamada en-aut-mei=Kiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OnoShigeki en-aut-sei=Ono en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Plastic and Reconstructive Surgery, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, General Medical Center, Kawasaki Medical School kn-affil= en-keyword=Neurofibromatosis type 1 kn-keyword=Neurofibromatosis type 1 en-keyword=Enucleation kn-keyword=Enucleation en-keyword=Eye kn-keyword=Eye en-keyword=Pathology kn-keyword=Pathology en-keyword=Massive retinal gliosis kn-keyword=Massive retinal gliosis en-keyword=Choroidal neurofibroma kn-keyword=Choroidal neurofibroma en-keyword=Phthisis kn-keyword=Phthisis en-keyword=Buphthalmos kn-keyword=Buphthalmos en-keyword=Malignant melanoma kn-keyword=Malignant melanoma en-keyword=Cosmetic surgery kn-keyword=Cosmetic surgery END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=8 article-no= start-page=208 end-page=214 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202408 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Anterior Uveitis After Discontinuation of Janus Kinase Inhibitor, Ruxolitinib en-subtitle= kn-subtitle= en-abstract= kn-abstract=Primary myelofibrosis shows widespread fibrosis in the bone marrow and is part of myeloproliferative neoplasms in which gene mutations in hematopoietic stem cells lead to abnormal clonal expansion of one or more lineage of myeloid and erythroid cells and megakaryocytes. Janus kinase (JAK) inhibitors are the main therapeutic regimen for primary myelofibrosis which harbors gene mutations, resulting in continuous activation of JAK-STAT signaling pathway. Since JAK inhibitors modulate immunological state, the administration would have a potential for uveitis. A 67-year-old patient presented with weight loss of 10 kg in the past 2 years after his retirement. He showed normocytic anemia with anisocytosis and abnormal shape, as well as hepatosplenomegaly. Suspected of hematological malignancy, bone marrow biopsy led to the diagnosis of primary myelofibrosis (grade 2) with bizarre megakaryocytes and relative maintenance of myeloid and erythroid lineage. He started to have blood transfusion. Genomic DNA analysis of the peripheral blood showed a pathogenic variant in the exon 9 of calreticulin (CALR) gene while pathogenic variants in Janus kinase-2 (JAK2), and myeloproliferative leukemia virus oncogene (MPL) were absent. He began to have oral ruxolitinib 10 mg daily at the timepoint of 5 months after the initial visit and the dose was increased to 20 mg daily 8 months later but was discontinued further 4 months later because he showed the limited effect of ruxolitinib. He had blood transfusion every week or every 2 weeks in the following 2 months until he noticed blurred vision in the right eye. The right eye showed thick fibrin membrane formation in the anterior chamber in front of the pupil which prevented the fundus from visualization. The left eye showed no inflammation and optic nerve atrophy, sequel to tuberculous meningitis in childhood. The patient started to use 0.1% betamethasone six times daily and 1% atropine once daily as eye drops. A week later, fibrin membrane disappeared and the pupillary area with total iris posterior synechia was visible in the right eye. He regained the vision in the right eye and did not show relapse of uveitis only with topical 0.1% betamethasone. Uveitis might be related with the administration and discontinuation of ruxolitinib. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IkedaNaoto en-aut-sei=Ikeda en-aut-mei=Naoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MonobeYasumasa en-aut-sei=Monobe en-aut-mei=Yasumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Internal Medicine, Kaneda Hospital kn-affil= affil-num=3 en-affil=Department of Pathology, General Medical Center, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Janus kinase inhibitor kn-keyword=Janus kinase inhibitor en-keyword=Ruxolitinib kn-keyword=Ruxolitinib en-keyword=Anemia kn-keyword=Anemia en-keyword=Myelofibrosis kn-keyword=Myelofibrosis en-keyword=Anterior uveitis kn-keyword=Anterior uveitis END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=5 article-no= start-page=804 end-page=810 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202409 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Augmented humoral response to third and fourth dose of SARS-CoV-2 mRNA vaccines in lung transplant recipients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Since lung transplant recipients (LTRs) exhibit low immunogenicity after two doses of SARS-CoV-2 mRNA vaccines, optimal vaccine strategies for SARS-CoV-2 are required in LTRs. This study aimed to investigate the efficacy and safety of the third and fourth doses of the SARS-CoV-2 mRNA vaccines in LTRs.
Methods: We conducted a single-center study of 73 LTRs and 23 healthy controls (HCs). Participants received two-to-four doses of SARS-CoV-2 mRNA vaccines. The LTRs were divided into three groups based on the number of vaccine dose. IgG titers against SARS-CoV-2 spike protein were measured, and adverse events were assessed. Factors associated with humoral response were analyzed using univariate and multivariate analyses.
Results: The Dose 4 group (n = 27) had a higher humoral response rate (P = 0.018) and higher levels of anti-SARS-CoV-2 IgG antibody (P = 0.04) than the Dose 2 group (n = 14). The Dose 3 group (n = 32) had lower humoral response rates (P = 0.005) and levels of anti-SARS-CoV-2 IgG antibody (P = 0.0005) than the HCs (n = 23) even after the same dose. Systemic adverse events were milder in the LTRs than in the HCs (P < 0.05). Increased number of vaccine dose was identified as a predictor of positive humoral response (P = 0.021).
Conclusion: Booster doses of SARS-CoV-2 mRNA vaccines may enhance humoral response with mild adverse events in LTRs. Repeated vaccination might be warranted for LTRs to prevent SARS-CoV-2 infection. en-copyright= kn-copyright= en-aut-name=KawanaShinichi en-aut-sei=Kawana en-aut-mei=Shinichi kn-aut-name= kn-aut-sei=

en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of proportions and prognostic impact of pathological complete response between evaluations of representative specimen and total specimen in primary breast cancer after neoadjuvant chemoradiotherapy: an ancillary study of JCOG0306 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background In JCOG0306 trial, a phase II study to examine the efficacy of neoadjuvant chemotherapy followed by radiation therapy (NAC-RT) to primary breast cancer, pathological complete response (pCR) was evaluated from specimens of the representative cross-section including the tumor center that had been accurately marked [representative specimen (RS) method]. In this ancillary study, we examined if the RS method was comparable to the conventional total specimen (TS) method, which is widely employed in Japan, to identify the pCR group showing excellent prognosis.
Methods We obtained long-term follow-up data of 103 patients enrolled in JCOG0306 trial. As histological therapeutic effect, pCR (ypT0 and ypT0/is) and quasi-pCR [QpCR, ypT0/is plus Grade 2b (only a few remaining invasive cancer cells)] were evaluated with RS and TS methods. Concordance of pCR between these two methods and associations of the pCR with prognosis were examined.
Results ypT0, ypT0/is, and QpCR were observed in 28 (27.2%), 39 (37.9%), and 45 (43.7%) patients with RS method, whereas these were 20 (19.4%), 25 (24.3%) and 40 (38.9%) with TS method, respectively. Between RS and TS methods, concordance proportions of ypT0 and ypTis were 92.2% and 86.4%, respectively. Risk of recurrence of ypT0/is group was lower than that of non-ypT0/is group (HR 0.408, 95% CI [0.175–0.946], P = 0.037) and risk of death of ypT0/is group was lower than that of non-ypT0/is group (HR 0.251, 95% CI [0.073–0.857], P = 0.027). The ypT0 and ypT0/is groups with RS method showed excellent prognosis similarly with those with TS method, and RS method was able to differentiate the OS and RFS between pCR and non-pCR than TS method significantly even if pCR was classified ypT0 or ypT0/is. With TS method, QpCR criteria stratified patients into the better and worse prognosis groupsmore clearly than pCR criteria of ypT0 or ypT0/is.
Conclusions RS method was comparable to TS method for the evaluation of pCR in the patients who received NAC-RT to primary breast cancer provided the tumor center was accurately marked. As pCR criteria with RS method, ypT0/is appeared more appropriate than ypT0. en-copyright= kn-copyright= en-aut-name=ShienTadahiko en-aut-sei=Shien en-aut-mei=Tadahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsudaHitoshi en-aut-sei=Tsuda en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SasakiKeita en-aut-sei=Sasaki en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizusawaJunki en-aut-sei=Mizusawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AkiyamaFutoshi en-aut-sei=Akiyama en-aut-mei=Futoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KurosumiMasafumi en-aut-sei=Kurosumi en-aut-mei=Masafumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SawakiMasataka en-aut-sei=Sawaki en-aut-mei=Masataka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TamuraNobuko en-aut-sei=Tamura en-aut-mei=Nobuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaKiyo en-aut-sei=Tanaka en-aut-mei=Kiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KogawaTakahiro en-aut-sei=Kogawa en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakahashiMina en-aut-sei=Takahashi en-aut-mei=Mina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HayashiNaoki en-aut-sei=Hayashi en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MukaiHirofumi en-aut-sei=Mukai en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MasudaNorikazu en-aut-sei=Masuda en-aut-mei=Norikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HaraFumikata en-aut-sei=Hara en-aut-mei=Fumikata kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=IwataHiroji en-aut-sei=Iwata en-aut-mei=Hiroji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Breast and Endocrine Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Basic Pathology, National Defense Medical College kn-affil= affil-num=3 en-affil=JCOG Data Center/Operations Office, National Cancer Center Hospital kn-affil= affil-num=4 en-affil=JCOG Data Center/Operations Office, National Cancer Center Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Cancer Institute Hospital kn-affil= affil-num=6 en-affil=Department of Diagnostic Pathology, Kameda Kyobashi Clinic kn-affil= affil-num=7 en-affil=Department of Breast Oncology, Aichi Cancer Center Hospital kn-affil= affil-num=8 en-affil=Department of Breast Surgery, Toranomon Hospital kn-affil= affil-num=9 en-affil=Department of Breast Surgery, Toranomon Hospital kn-affil= affil-num=10 en-affil=Department of Breast Medical Oncology, Cancer Institute Hospital kn-affil= affil-num=11 en-affil=Department of Breast Oncology, National Hospital Organization Shikoku Cancer Center kn-affil= affil-num=12 en-affil=Department of Breast Surgery Oncology, St Lukes International Hospital kn-affil= affil-num=13 en-affil=Department of Breast and Medical Oncology, National Cancer Center Hospital East kn-affil= affil-num=14 en-affil=Department of Surgery, Breast Oncology, National Hospital Organization Osaka National Hospital kn-affil= affil-num=15 en-affil=Department of Breast Medical Oncology, Cancer Institute Hospital kn-affil= affil-num=16 en-affil=Department of Breast Oncology, Aichi Cancer Center Hospital kn-affil= en-keyword=Breast cancer kn-keyword=Breast cancer en-keyword=Neoadjuvant chemoradiotherapy kn-keyword=Neoadjuvant chemoradiotherapy en-keyword=Pathological therapeutic effect kn-keyword=Pathological therapeutic effect en-keyword=Specimen sampling method kn-keyword=Specimen sampling method END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page=1383309 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240606 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Late-onset renal variant Fabry disease with R112H mutation and mild increase in plasma globotriaosylsphingosine: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fabry disease (FD) is an X-linked disorder resulting in a deficiency of alpha-galactosidase A (GLA) activity. The R112H mutation of GLA is relatively common in Japanese FD patients, characterized by a late-onset phenotype, almost normal to mild lyso-Gb3 elevation, and mild clinical symptoms, despite low GLA activity. This is due to the structural features of the R112H GLA protein. We herein report the case of a 42-year-old male patient with late-onset FD with a R112H mutation. The patient exhibited only renal involvement with no other organ damage and was successfully treated with galactosidase beta and subsequent migalastat for approximately 10 years. Especially, migalastat was clinically effective in normalizing plasma lyso-Gb3 levels and inhibiting the progression of renal damage associated with FD. Therefore, the use of migalastat in the FD patients with R112H mutation is highly recommended based on this case report. en-copyright= kn-copyright= en-aut-name=TanakaKeiko en-aut-sei=Tanaka en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugiyamaHitoshi en-aut-sei=Sugiyama en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorinagaHiroshi en-aut-sei=Morinaga en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OnishiAkifumi en-aut-sei=Onishi en-aut-mei=Akifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanabeKatsuyuki en-aut-sei=Tanabe en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaHaruhito A. en-aut-sei=Uchida en-aut-mei=Haruhito A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaruyamaHiroki en-aut-sei=Maruyama en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University kn-affil= affil-num=4 en-affil=Department of Nephrology, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University kn-affil= affil-num=6 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University kn-affil= affil-num=7 en-affil=Department of Clinical Nephroscience, Niigata University Graduate School of Medical and Dental Sciences kn-affil= affil-num=8 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University kn-affil= en-keyword=Fabry disease kn-keyword=Fabry disease en-keyword=R112H mutation kn-keyword=R112H mutation en-keyword=migalastat kn-keyword=migalastat en-keyword=proteinuria kn-keyword=proteinuria en-keyword=chronic kidney disease kn-keyword=chronic kidney disease END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=1 article-no= start-page=4600 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240530 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photoinduced dynamics during electronic transfer from narrow to wide bandgap layers in one-dimensional heterostructured materials en-subtitle= kn-subtitle= en-abstract= kn-abstract=Electron transfer is a fundamental energy conversion process widely present in synthetic, industrial, and natural systems. Understanding the electron transfer process is important to exploit the uniqueness of the low-dimensional van der Waals (vdW) heterostructures because interlayer electron transfer produces the function of this class of material. Here, we show the occurrence of an electron transfer process in one-dimensional layer-stacking of carbon nanotubes (CNTs) and boron nitride nanotubes (BNNTs). This observation makes use of femtosecond broadband optical spectroscopy, ultrafast time-resolved electron diffraction, and first-principles theoretical calculations. These results reveal that near-ultraviolet photoexcitation induces an electron transfer from the conduction bands of CNT to BNNT layers via electronic decay channels. This physical process subsequently generates radial phonons in the one-dimensional vdW heterostructure material.

en-subtitle= kn-subtitle= en-abstract= kn-abstract=A Japanese woman in her 70s was referred to our hospital for the evaluation and treatment of high intraocular pressure (IOP) in her right eye. She had undergone bilateral cataract surgeries and the insertion of hydrophilic acrylic intraocular lenses (IOLs). We performed trabeculotomy and trabeculectomy to lower her right IOP; thereafter, a circular opacity was observed on the right eye’s IOL surface. We removed the right IOL because that eye’s vision had decreased due to IOL opacification. The analysis of the removed IOL revealed that the main opacity component was calcium phosphate. This is the first post-glaucoma-surgery IOL calcification case report. en-copyright= kn-copyright= en-aut-name=OkamotoSara en-aut-sei=Okamoto en-aut-mei=Sara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShiodeYusuke en-aut-sei=Shiode en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KimuraShuhei en-aut-sei=Kimura en-aut-mei=Shuhei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HosokawaMio en-aut-sei=Hosokawa en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KanzakiYuki en-aut-sei=Kanzaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KindoHiroya en-aut-sei=Kindo en-aut-mei=Hiroya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MoritaTetsuro en-aut-sei=Morita en-aut-mei=Tetsuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsujiAkihiro en-aut-sei=Tsuji en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TakahashiKosuke en-aut-sei=Takahashi en-aut-mei=Kosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Fukuyama City Hospital kn-affil= affil-num=10 en-affil=Fukuyama City Hospital kn-affil= affil-num=11 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=intraocular lens kn-keyword=intraocular lens en-keyword=IOL kn-keyword=IOL en-keyword=IOL calcification kn-keyword=IOL calcification en-keyword=hydrophilic acrylic IOL kn-keyword=hydrophilic acrylic IOL en-keyword=glaucoma surgery kn-keyword=glaucoma surgery END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=3 article-no= start-page=245 end-page=250 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202406 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Reduced Skeletal Muscle Mass on Patients with Knee Osteoarthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although several studies have suggested a possible association between sarcopenia and knee osteoarthritis (OA) in the elderly, there remains no definitive evidence. Recently, however, the serum creatinine/cystatin C ratio (sarcopenia index: SI) was reported to correlate with skeletal muscle mass. The present retrospective study therefore investigated the impact of reduced skeletal muscle mass on advanced knee OA using SI. In 55 individuals scheduled for knee osteotomy or knee arthroplasty, correlations between SI and patient-reported outcomes such as the Knee Society Score (KSS), Knee Injury and Osteoarthritis Outcome Score (KOOS), and Oxford Knee Score (OKS) were explored. Significant associations were found between SI and the KSS functional activity score (β=0.37; p=0.022), KOOS subscale for activities of daily living (β=0.42; p=0.0096), and OKS (β=0.42; p=0.0095). This study underscores the role of reduced muscle mass in functional outcomes and introduces SI as a valuable marker for assessing muscle loss in knee OA patients. en-copyright= kn-copyright= en-aut-name=AkagawaManabu en-aut-sei=Akagawa en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoHidetomo en-aut-sei=Saito en-aut-mei=Hidetomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiYasuhiro en-aut-sei=Takahashi en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwamotoYosuke en-aut-sei=Iwamoto en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IidaJunpei en-aut-sei=Iida en-aut-mei=Junpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshikawaTakayuki en-aut-sei=Yoshikawa en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AbeToshiki en-aut-sei=Abe en-aut-mei=Toshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaitoKimio en-aut-sei=Saito en-aut-mei=Kimio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KijimaHiroaki en-aut-sei=Kijima en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KasukawaYuji en-aut-sei=Kasukawa en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=HongoMichio en-aut-sei=Hongo en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyakoshiNaohisa en-aut-sei=Miyakoshi en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Omagari Kousei Medical Center kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=knee osteoarthritis kn-keyword=knee osteoarthritis en-keyword=sarcopenia index kn-keyword=sarcopenia index en-keyword=reduced muscle mass kn-keyword=reduced muscle mass en-keyword=activities of daily living kn-keyword=activities of daily living en-keyword=functional activity kn-keyword=functional activity END start-ver=1.4 cd-journal=joma no-vol=63 cd-vols= no-issue=9 article-no= start-page=1261 end-page=1267 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240501 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Severe Cytokine Release Syndrome and Immune Effector Cell-associated Neurotoxicity Syndrome in a Man Receiving Immune Checkpoint Inhibitors for Lung Cancer en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 55-year-old man with stage IV lung adenocarcinoma was treated with cisplatin, pemetrexed, nivolumab, and ipilimumab. Approximately 100 days after treatment initiation, he became disoriented and presented to the emergency department with a high fever. Blood tests revealed liver and kidney dysfunctions. Subsequently, the patient developed generalized convulsions that required intensive care. He was clinically diagnosed with cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Organ damage was gradually controlled with immunosuppressive drugs, including steroids, and the patient was discharged. Successful treatment is rare in patients with CRS, including ICANS, during immune checkpoint inhibitor treatment for solid tumors. en-copyright= kn-copyright= en-aut-name=TanakaTakaaki

Upper, lower, or both fornix lesions in 28 patients were all diagnosed as extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma), while thick nasal bulbar conjunctival lesions in 3 patients were differently diagnosed as MALT lymphoma, diffuse large B-cell lymphoma, and follicular lymphoma, respectively. Seven patients underwent local radiation (30 Gy): as initial treatment in 5 patients and treatment for relapse in 2 patients. The remaining 24 patients were observed without additional treatment after excisional biopsy: 5 of these 24 patients showed relapse 0.5 to 6 years later and underwent excisional biopsy again that revealed MALT lymphoma. Of the 5 patients with relapse, only one with second-time relapse underwent radiation. Fluorodeoxyglucose positron emission tomography was performed in 18 patients and showed no systemic lesions: high uptake was noted in the residual conjunctival lesions of 4 patients and in the relapsed conjunctival lesions of 3 patients. One patient died of rectal cancer while no patients died of lymphoma. Observation is an option in patients with primary conjunctival lymphoma after excisional biopsy. Radiation is a treatment option in the case of relapse. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword= conjunctival lymphoma kn-keyword= conjunctival lymphoma en-keyword=extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) kn-keyword=extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) en-keyword=follicular lymphoma kn-keyword=follicular lymphoma en-keyword=diffuse large B-cell lymphoma kn-keyword=diffuse large B-cell lymphoma en-keyword=fluorodeoxyglucose positron emission tomography (FDG-PET) kn-keyword=fluorodeoxyglucose positron emission tomography (FDG-PET) END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=5 article-no= start-page=e8933 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202405 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Decades of stability of conjunctival vascular malformations in two patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 65-year-old woman with diabetic retinopathy underwent glaucoma surgery to construct a filtering bleb adjacent to conjunctival hemangioma, and showed bleb function and stable hemangioma for a decade.

The precise division of the intersegmental plane is necessary to ensure oncologic margins from the tumor and to preserve the lung function. In this study, we present a strategy for accurately dividing the intersegmental plane using a robotic stapler and review the surgical outcomes.
Methods RATS portal segmentectomy was performed using the Da Vinci Xi system and the intersegmental plane was dissected using a robotic stapler. We evaluated the perioperative outcomes in 92 patients who underwent RATS portal segmentectomy between May 2020 and January 2023. These results were compared with those of 82 patients who underwent complete video-assisted thoracoscopic surgery (CVATS) during the same period.
Results The operative and console times were 162 and 97 min, respectively. No intraoperative complications occurred, and postoperative complications were observed in four cases (4.3%). The operative time, blood loss, postoperative complications, and maximum incision size were significantly lower in the RATS group than in the CVATS group. However, RATS requires a significantly higher number of staplers than CVATS.
Conclusions The division of the intersegmental plane using a robotic stapler in RATS portal segmentectomy was, therefore, found to be safe and effective. en-copyright= kn-copyright= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HashimotoKohei en-aut-sei=Hashimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Pulmonary segmentectomy kn-keyword=Pulmonary segmentectomy en-keyword=Robot-assisted thoracic surgery kn-keyword=Robot-assisted thoracic surgery en-keyword=Robotic segmentectomy kn-keyword=Robotic segmentectomy en-keyword=Robotic stapler kn-keyword=Robotic stapler END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=1 article-no= start-page=140 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240422 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic manifestation of intestinal transplant-associated microangiopathy after stem cell transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Endoscopic features of intestinal transplant-associated microangiopathy (iTAM) have not been comprehensively investigated. This study aimed to examine the endoscopic characteristics of patients diagnosed with iTAM.
Methods This retrospective analysis included 14 patients pathologically diagnosed with iTAM after stem cell transplantation for hematolymphoid neoplasms (n = 13) or thalassemia (n = 1). The sex, age at diagnosis, endoscopic features, and prognosis of each patient were assessed. Serological markers for diagnosing transplant-associated thrombotic microangiopathy were also evaluated.
Results The mean age at the time of iTAM diagnosis was 40.2 years. Patients diagnosed based on the pathognomonic pathological changes of iTAM presented with diverse symptoms at the times of endoscopic examinations, including diarrhea (n = 10), abdominal pain (n = 5), nausea (n = 4), appetite loss (n = 2), bloody stools (n = 2), abdominal discomfort (n = 1), and vomiting (n = 1). At the final follow-up, six patients survived, while eight patients succumbed, with a median time of 100.5 days (range: 52-247) post-diagnosis. Endoscopic manifestations included erythematous mucosa (n = 14), erosions (n = 13), ulcers (n = 9), mucosal edema (n = 9), granular mucosa (n = 9), and villous atrophy (n = 4). Erosions and/or ulcers were primarily observed in the colon (10/14, 71%), followed by the ileum (9/13, 69%), stomach (4/10, 40%), cecum (5/14, 36%), duodenum (3/10, 30%), rectum (4/14, 29%), and esophagus (1/10, 10%). Cytomegalovirus infection (n = 4) and graft-versus-host disease (n = 2) coexisted within the gastrointestinal tract. Patients had de novo prolonged or progressive thrombocytopenia (6/14, 43%), decreased hemoglobin concentration (4/14, 29%), reduced serum haptoglobin level (3/14, 21%), and a sudden and persistent increase in lactate dehydrogenase level (2/14, 14%). Peripheral blood samples from 12 patients were evaluated for schistocytes, with none exceeding 4%.
Conclusions This study provides a comprehensive exploration of the endoscopic characteristics of iTAM. Notably, all patients exhibited erythematous mucosa throughout the gastrointestinal tract, accompanied by prevalent manifestations, such as erosions (93%), ulcers (64%), mucosal edema (64%), granular mucosa (64%), and villous atrophy (29%). Because of the low positivity for serological markers of transplant-associated thrombotic microangiopathy in patients with iTAM, endoscopic evaluation and biopsy of these lesions are crucial, even in the absence of these serological features. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsuokaKen-Ichi en-aut-sei=Matsuoka en-aut-mei=Ken-Ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Colonoscopy kn-keyword=Colonoscopy en-keyword=Esophagogastroduodenoscopy kn-keyword=Esophagogastroduodenoscopy en-keyword=Graft-versus-host disease kn-keyword=Graft-versus-host disease en-keyword=Hematopoietic stem cell transplantation kn-keyword=Hematopoietic stem cell transplantation en-keyword=Intestinal transplant-associated microangiopathy kn-keyword=Intestinal transplant-associated microangiopathy en-keyword=iTAM kn-keyword=iTAM END start-ver=1.4 cd-journal=joma no-vol=136 cd-vols= no-issue=1 article-no= start-page=7 end-page=11 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240401 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Intraoperative diagnosis of brain tumors using fluorescent probes kn-title=脳腫瘍の術中蛍光診断 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TanakaShota en-aut-sei=Tanaka en-aut-mei=Shota kn-aut-name=田中將太 kn-aut-sei=田中 kn-aut-mei=將太 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Faculty of Medicine, Dentistry and Pharmaceutical Sciences.

Living donor lobar lung transplantation is a life-saving procedure for critically ill patients. This requires 2 healthy donors exposed to risks and without medical benefit. Therefore, the donor's safety and minimal postoperative complications are crucial. This study aimed to investigate the short-term outcomes and identify the risk factors affecting these outcomes. Methods. The data of 175 living donors enrolled between 1998 and 2022 were analyzed. Donors were divided into era 1 (1998-2009) and era 2 (2010-2022). Results. The overall incidence of postoperative complications was 39%, of which 7% were major complications. Donors who underwent surgery on the right side had a higher incidence of delayed pulmonary fistulae (P = 0.01) and elevated liver enzyme levels (P = 0.028). Living donor surgery on the right side (P = 0.01), era 2 (P = 0.01), and the need for plasty (P = 0.04) were predictors of postoperative complications. Conclusions. Updated data on complications and their correlation with postoperative quality of life from this study could aid in the selection of potential donors and facilitate informed consent. en-copyright=

Patients with Type 2 Diabetes: A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=The global pandemic of coronavirus infection 2019 (COVID-19) was an unprecedented public health emergency. Several clinical studies reported that heart disease, lung disease, diabetes, hypertension, dyslipidemia, and obesity are critical risk factors for increased severity of and hospitalization for COVID-19. This is largely because patients with these underlying medical conditions can show poor immune responses to the COVID-19 vaccinations. Diabetes is one of the underlying conditions most highly associated with COVID-19 susceptibility and is considered a predictor of poor prognosis of COVID-19. We therefore investigated factors that influence the anti-SARS-CoV-2 spike IgG antibody titer after three doses of vaccination in patients with type 2 diabetes. We found that obesity was associated with low anti-SARS-CoV-2 spike IgG antibody titers following three-dose vaccination in type 2 diabetics. Obese patients with type 2 diabetes may have attenuated vaccine efficacy and require additional vaccination; continuous infection control should be considered in such patients. en-copyright= kn-copyright= en-aut-name=TakahashiHiroko en-aut-sei=Takahashi en-aut-mei=Hiroko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EguchiJun en-aut-sei=Eguchi en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeMayu en-aut-sei=Watanabe en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakayamaMasanori en-aut-sei=Nakayama en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WadaJun en-aut-sei=Wada en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Office of Innovative Medicine, Organization for Research Strategy and Development, Okayama University kn-affil= affil-num=5 en-affil=Department of Nephrology, Rheumatology, Endocrinology, and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=obesity kn-keyword=obesity en-keyword=type 2 diabetes kn-keyword=type 2 diabetes en-keyword=COVID-19 kn-keyword=COVID-19 en-keyword=vaccination kn-keyword=vaccination END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=163 end-page=170 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Impact of Light Touch and Pin Prick on Functional Outcomes in Patients with Traumatic Spinal Cord Injury en-subtitle= kn-subtitle= en-abstract= kn-abstract=A spinal cord injury (SCI) can cause severe lifelong functional disability and profoundly affect an individual’s daily life. We investigated the prediction of patients’ post-SCI functional outcomes by evaluating sensory scores rather than motor scores, as the latter’s association with functional outcomes is well established. We examined patients’ responses to a light touch (LT) and pin prick (PP) at admission and the response data’s usefulness as predictors of functional outcomes (i.e., ability to perform activities of daily living) at discharge. This exploratory observational study used data from the Japanese National Spinal Cord Injury Database (SCI-J). Data from 3,676 patients who met the inclusion criteria and were admitted for an SCI between 1997 and 2020 were analyzed. The motor score of the Functional Independence Measure (mFIM) at discharge was used as an index of functional outcome. A multiple regression analysis revealed that the mFIM was associated with both the LT response (β=0.07 (0.01), p<0.001) and the PP response (β=0.07 (0.01), p<0.001) at admission. The false discovery rate log-worth values for LT and PP were 6.6 and 8.5, respectively. Our findings demonstrate that LT and PP scores at admission can help predict patients’ functional outcomes after an SCI, although the magnitude of their contributions is not high. en-copyright= kn-copyright= en-aut-name=DeguchiTakayuki en-aut-sei=Deguchi en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KandaKanae en-aut-sei=Kanda en-aut-mei=Kanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FurusawaKazunari en-aut-sei=Furusawa en-aut-mei=Kazunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=Nlandu Roger Ngatu en-aut-sei=Nlandu Roger Ngatu en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiraoTomohiro en-aut-sei=Hirao en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=3 en-affil=Department of Rehabilitation Medicine, Kibikogen Rehabilitation Center for Employment Injuries kn-affil= affil-num=4 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= affil-num=5 en-affil=Department of Public Health, Faculty of Medicine, Kagawa University kn-affil= en-keyword=functional independence measure kn-keyword=functional independence measure en-keyword=light touch kn-keyword=light touch en-keyword=pin prick kn-keyword=pin prick en-keyword=spinal cord injury kn-keyword=spinal cord injury en-keyword=Japanese National Spinal Cord Injury Database kn-keyword=Japanese National Spinal Cord Injury Database END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=151 end-page=161 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=p53-Armed Oncolytic Virotherapy Improves Radiosensitivity in Soft-Tissue Sarcoma by Suppressing BCL-xL Expression en-subtitle= kn-subtitle= en-abstract= kn-abstract=Soft-tissue sarcoma (STS) is a heterogeneous group of rare tumors originating predominantly from the embryonic mesoderm. Despite the development of combined modalities including radiotherapy, STSs are often refractory to antitumor modalities, and novel strategies that improve the prognosis of STS patients are needed. We previously demonstrated the therapeutic potential of two telomerase-specific replication-competent oncolytic adenoviruses, OBP-301 and tumor suppressor p53-armed OBP-702, in human STS cells. Here, we demonstrate in vitro and in vivo antitumor effects of OBP-702 in combination with ionizing radiation against human STS cells (HT1080, NMS-2, SYO-1). OBP-702 synergistically promoted the antitumor effect of ionizing radiation in the STS cells by suppressing the expression of B-cell lymphoma-X large (BCL-xL) and enhancing ionizing radiation-induced apoptosis. The in vivo experiments demonstrated that this combination therapy significantly suppressed STS tumors’ growth. Our results suggest that OBP-702 is a promising antitumor reagent for promoting the radiosensitivity of STS tumors. en-copyright= kn-copyright= en-aut-name=KomatsubaraTadashi en-aut-sei=Komatsubara en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TazawaHiroshi en-aut-sei=Tazawa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaseiJoe en-aut-sei=Hasei en-aut-mei=Joe kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OmoriToshinori en-aut-sei=Omori en-aut-mei=Toshinori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiuKazuhisa en-aut-sei=Sugiu en-aut-mei=Kazuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MochizukiYusuke en-aut-sei=Mochizuki en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DemiyaKoji en-aut-sei=Demiya en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshidaAki en-aut-sei=Yoshida en-aut-mei=Aki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KunisadaToshiyuki en-aut-sei=Kunisada en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UrataYasuo en-aut-sei=Urata en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Oncolys BioPharma, Inc. kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=soft-tissue sarcoma kn-keyword=soft-tissue sarcoma en-keyword=radiotherapy kn-keyword=radiotherapy en-keyword=oncolytic adenovirus kn-keyword=oncolytic adenovirus en-keyword=p53 kn-keyword=p53 en-keyword=BCL-xL kn-keyword=BCL-xL END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=143 end-page=149 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of Travel Distance on Surgical Outcomes of Patients Surgically Treated for Non-Small Cell Lung Cancer: A Single-Center Study in Ehime, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Travel burden is a poor prognostic factor for many cancers worldwide because it hinders optimal diagnosis and treatment planning. Currently, the impact of travel burden on survival after surgery for non-small cell lung cancer (NSCLC) in Japan is largely unexplored. We examined the impact of travel distance on the postoperative outcomes of patients with NSCLC in Ehime Prefecture, Japan. The data of 1212 patients who underwent surgical resection for NSCLC were retrospectively reviewed. Patients were divided into quartiles based on the travel distance from their home to the hospital (≤ 13 km, 13-40 km, 40-57 km, and > 57 km) in Ehime Prefecture. We found no significant differences among the quartiles in baseline clinicopathological characteristics, including sex, smoking status, histology, surgical procedure, clinical stage, and pathological stage. Overall survival (OS) and relapse-free survival (RFS) also were not significantly different among the travel distance quartiles. We conclude that travel distance did not impact OS or RFS among patients with NSCLC who underwent surgical resection at our institution. en-copyright= kn-copyright= en-aut-name=ShigematsuHisayuki en-aut-sei=Shigematsu en-aut-mei=Hisayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamashitaNatsumi en-aut-sei=Yamashita en-aut-mei=Natsumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuehisaHiroshi en-aut-sei=Suehisa en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UenoTsuyoshi en-aut-sei=Ueno en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=RyukoTsuyoshi en-aut-sei=Ryuko en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugiharaTakahito en-aut-sei=Sugihara en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakashimaShohei en-aut-sei=Nakashima en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SanoYoshifumi en-aut-sei=Sano en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YamashitaMotohiro en-aut-sei=Yamashita en-aut-mei=Motohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Clinical Research Center, NHO Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= affil-num=8 en-affil=Department of Cardiovascular and Thoracic Surgery, Ehime University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Thoracic Surgery, NHO Shikoku Cancer Center kn-affil= en-keyword=non-small cell lung cancer kn-keyword=non-small cell lung cancer en-keyword=travel distance kn-keyword=travel distance en-keyword=travel burden kn-keyword=travel burden en-keyword=lung surgery kn-keyword=lung surgery en-keyword=surgical outcome kn-keyword=surgical outcome END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=135 end-page=142 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Photon-Counting Detector CT: Potential for 75% Reduction in Contrast Medium Amount: A Phantom Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to evaluate the potential reduction in contrast medium utilization using photon-counting detector computed tomography (PCD-CT). One PCD-CT scan (CT1) and three conventional (non-PCD-CT) CT scans (CT2-CT4) were performed using a multi-energy CT phantom that contained eight rods with different iodine concentrations (0.2, 0.5, 1, 2, 5, 10, 15, and 20 mg/ml). The CT values of the seven groups (CT1 for 40, 50, 60, and 70 keV; and CT2-4) were measured. Noise and contrast-to-noise ratio (CNR) were assessed for the eight rods at various iodine concentrations. CT2 and CT1 (40 keV) respectively required 20 mg/ml and 5 mg/ml of iodine, indicating that a comparable contrast effect could be obtained with approximately one-fourth of the contrast medium amount. The standard deviation values increased at lower energy levels irrespective of the iodine concentration. The CNR exhibited a decreasing trend with lower iodine concentrations, while it remained relatively stable across all iodine levels (40-70 keV). This study demonstrated that virtual monochromatic 40 keV images offer a similar contrast effect with a reduced contrast medium amount when compared to conventional CT systems at 120 kV. en-copyright= kn-copyright= en-aut-name=HigakiFumiyo en-aut-sei=Higaki en-aut-mei=Fumiyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MorimitsuYusuke en-aut-sei=Morimitsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IguchiToshihiro en-aut-sei=Iguchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoHayato en-aut-sei=Saito en-aut-mei=Hayato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakakiHaruhiko en-aut-sei=Takaki en-aut-mei=Haruhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakagoshiAyako en-aut-sei=Nakagoshi en-aut-mei=Ayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WadaMaki en-aut-sei=Wada en-aut-mei=Maki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UkaMayu en-aut-sei=Uka en-aut-mei=Mayu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AkagiNoriaki en-aut-sei=Akagi en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MatsuiYusuke en-aut-sei=Matsui en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Faculty of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Medical School kn-affil= affil-num=8 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Radiological Technology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Radiology, Okayama University Faculty of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=photon-counting detector CT kn-keyword=photon-counting detector CT en-keyword=energy integrating detector CT kn-keyword=energy integrating detector CT en-keyword=computed tomography kn-keyword=computed tomography en-keyword=contrast medium amount kn-keyword=contrast medium amount en-keyword=reduction kn-keyword=reduction END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=123 end-page=134 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Sigle Agent of Posttransplant Cyclophosphamide Without Calcineurin Inhibitor Controls Severity of Experimental Chronic GVHD en-subtitle= kn-subtitle= en-abstract= kn-abstract=Chronic graft-versus-host disease (GVHD) is a major cause of late death and morbidity following allogeneic hematopoietic cell transplantation (HCT), but its pathogenesis remains unclear. Recently, haplo-identical HCT with post-transplant cyclophosphamide (Haplo-HCT with PTCY) was found to achieve a low incidence rate of acute GVHD and chronic GVHD. However, while the pathogenesis of acute GVHD following Haplo-HCT with PTCY has been well investigated, that of chronic GVHD remains to be elucidated, especially in HLA-matched HCT with PTCY. Based on its safety profile, PTCY is currently applied for the human leucocyte antigen (HLA)-matched HCT setting. Here, we investigated the mechanisms of chronic GVHD following HLA-matched HCT with PTCY using a well-defined mouse chronic GVHD model. PTCY attenuated clinical and pathological chronic GVHD by suppressing effector T-cells and preserving regulatory T-cells compared with a control group. Additionally, we demonstrated that cyclosporine A (CsA) did not show any additional positive effects on attenuation of GVHD in PTCY-treated recipients. These results suggest that monotherapy with PTCY without CsA could be a promising strategy for the prevention of chronic GVHD following HLA-matched HCT. en-copyright= kn-copyright= en-aut-name=SaekiKyosuke en-aut-sei=Saeki en-aut-mei=Kyosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FujiwaraHideaki en-aut-sei=Fujiwara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SeikeKeisuke en-aut-sei=Seike en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KuroiTaiga en-aut-sei=Kuroi en-aut-mei=Taiga kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimoriHisakazu en-aut-sei=Nishimori en-aut-mei=Hisakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Division of Transfusion, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=GVHD kn-keyword=GVHD en-keyword=posttransplant cyclophosphamide kn-keyword=posttransplant cyclophosphamide en-keyword=hematopoietic cell transplantation kn-keyword=hematopoietic cell transplantation en-keyword=HLA-identical kn-keyword=HLA-identical END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=95 end-page=106 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Roles of Neuropeptide Y in Respiratory Disease Pathogenesis via the Airway Immune Response en-subtitle= kn-subtitle= en-abstract= kn-abstract=The lungs are very complex organs, and the respiratory system performs the dual roles of repairing tissue while protecting against infection from various environmental stimuli. Persistent external irritation disrupts the immune responses of tissues and cells in the respiratory system, ultimately leading to respiratory disease. Neuropeptide Y (NPY) is a 36-amino-acid polypeptide and a neurotransmitter that regulates homeostasis. The NPY receptor is a seven-transmembrane-domain G-protein-coupled receptor with six subtypes (Y1, Y2, Y3, Y4, Y5, and Y6). Of these receptors, Y1, Y2, Y4, and Y5 are functional in humans, and Y1 plays important roles in the immune responses of many organs, including the respiratory system. NPY and the Y1 receptor have critical roles in the pathogenesis of asthma, chronic obstructive pulmonary disease, and idiopathic pulmonary fibrosis. The effects of NPY on the airway immune response and pathogenesis differ among respiratory diseases. This review focuses on the involvement of NPY in the airway immune response and pathogenesis of various respiratory diseases. en-copyright= kn-copyright= en-aut-name=ItanoJunko en-aut-sei=Itano en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyaharaNobuaki en-aut-sei=Miyahara en-aut-mei=Nobuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Hematology, Oncology and Respiratory Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Allergy and Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=neuropeptide y kn-keyword=neuropeptide y en-keyword=Y1 receptor kn-keyword=Y1 receptor en-keyword=airway immune response kn-keyword=airway immune response en-keyword=bronchial epithelial cells kn-keyword=bronchial epithelial cells en-keyword=respiratory disease kn-keyword=respiratory disease END start-ver=1.4 cd-journal=joma no-vol=53 cd-vols= no-issue=11 article-no= start-page=1009 end-page=1018 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230825 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Advances in treatment of alveolar soft part sarcoma: an updated review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Alveolar soft part sarcoma is a rare neoplasm of uncertain histogenesis that belongs to a newly defined category of ultra-rare sarcomas. The neoplasm is characterized by a specific chromosomal translocation, der (17) t(X; 17)(p11.2;q25), that results in ASPSCR1–TFE3 gene fusion. The natural history of alveolar soft part sarcoma describes indolent behaviour with slow progression in deep soft tissues of the extremities, trunk and head/neck in adolescents and young adults. A high rate of detection of distant metastasis at presentation has been reported, and the most common metastatic sites in decreasing order of frequency are the lung, bone and brain. Complete surgical resection remains the standard treatment strategy, whereas radiotherapy is indicated for patients with inadequate surgical margins or unresectable tumours. Although alveolar soft part sarcoma is refractory to conventional doxorubicin-based chemotherapy, monotherapy or combination therapy using tyrosine kinase inhibitors and immune checkpoint inhibitors have provided antitumor activity and emerged as new treatment strategies. This article provides an overview of the current understanding of this ultra-rare sarcoma and recent advancements in treatments according to the clinical stage of alveolar soft part sarcoma. en-copyright= kn-copyright= en-aut-name=FujiwaraTomohiro en-aut-sei=Fujiwara en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KunisadaToshiyuki en-aut-sei=Kunisada en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakataEiji en-aut-sei=Nakata en-aut-mei=Eiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraTomoki en-aut-sei=Nakamura en-aut-mei=Tomoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaKazuhiro en-aut-sei=Tanaka en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Mie University kn-affil= affil-num=7 en-affil=Department of Advanced Medical Sciences, Oita University kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=alveolar soft part sarcoma kn-keyword=alveolar soft part sarcoma en-keyword=surgery kn-keyword=surgery en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=targeted therapy kn-keyword=targeted therapy en-keyword=immunotherapy kn-keyword=immunotherapy END start-ver=1.4 cd-journal=joma no-vol=160 cd-vols= no-issue=9 article-no= start-page=094101 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240301 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=GenIce-core: Efficient algorithm for generation of hydrogen-disordered ice structures en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ice is different from ordinary crystals because it contains randomness, which means that statistical treatment based on ensemble averaging is essential. Ice structures are constrained by topological rules known as the ice rules, which give them unique anomalous properties. These properties become more apparent when the system size is large. For this reason, there is a need to produce a large number of sufficiently large crystals that are homogeneously random and satisfy the ice rules. We have developed an algorithm to quickly generate ice structures containing ions and defects. This algorithm is provided as an independent software module that can be incorporated into crystal structure generation software. By doing so, it becomes possible to simulate ice crystals on a previously impossible scale. en-copyright= kn-copyright= en-aut-name=MatsumotoMasakazu en-aut-sei=Matsumoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YagasakiTakuma en-aut-sei=Yagasaki en-aut-mei=Takuma kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Division of Chemical Engineering, Graduate School of Engineering Science, Osaka University kn-affil= affil-num=3 en-affil=Toyota Physical and Chemical Research Institute kn-affil= END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=1 article-no= start-page=4953 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term monitoring of gastric mucosa-associated lymphoid tissue lymphoma in patients with extra copies of the MALT1 gene en-subtitle= kn-subtitle= en-abstract= kn-abstract=The objective of this study was to clarify the long-term prognosis of patients with gastric mucosa-associated lymphoid tissue (MALT) lymphoma with additional copies of MALT1. In this multicenter retrospective study, we enrolled 145 patients with gastric MALT lymphoma who underwent fluorescence in situ hybridization (FISH) analysis to detect t(11;18) translocation. The patient cohort was divided into three groups: Group A (n = 87), comprising individuals devoid of the t(11;18) translocation or extra MALT1 copies; Group B (n = 27), encompassing patients characterized by the presence of the t(11;18) translocation; and Group C (n = 31), including patients with extra MALT1 copies. The clinical outcomes in each cohort were collected. Over the course of a mean follow-up of 8.5 ± 4.2 years, one patient died of progressive MALT lymphoma, while 15 patients died due to etiologies unrelated to lymphoma. The progression or relapse of MALT lymphoma was observed in 11 patients: three in Group A, two in Group B, and six in Group C. In Groups A, B, and C, the 10-year overall survival rates were 82.5%, 93.8%, and 86.4%, respectively, and the 10-year event-free survival rates were 96.1%, 96.0%, and 82.9%, respectively. The event-free survival rate in Group C was significantly lower than that in Group A. However, no differences were observed in the 10-year event-free survival rates among individuals limited to stage I or II1 disease (equivalent to excluding patients with stage IV disease in this study, as there were no patients with stage II2), with rates of 98.6%, 95.8%, and 92.3% for Groups A, B, and C, respectively. In conclusion, the presence of extra copies of MALT1 was identified as an inferior prognostic determinant of event-free survival. Consequently, trisomy/tetrasomy 18 may serve as an indicator of progression and refractoriness to therapeutic intervention in patients with gastric MALT lymphoma, particularly stage IV gastric MALT lymphoma. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyaharaKoji en-aut-sei=Miyahara en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OkanoueShotaro en-aut-sei=Okanoue en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshiokaMasao en-aut-sei=Yoshioka en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SakaguchiChihiro en-aut-sei=Sakaguchi en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamamotoKumiko en-aut-sei=Yamamoto en-aut-mei=Kumiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KawaiYoshinari en-aut-sei=Kawai en-aut-mei=Yoshinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil= Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Hiroshima City Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Mitoyo General Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Onomichi Municipal Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Fukuyama Medical Center kn-affil= affil-num=10 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue kn-keyword=Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue en-keyword=Gastric neoplasms kn-keyword=Gastric neoplasms en-keyword=Esophagogastroduodenoscopy kn-keyword=Esophagogastroduodenoscopy en-keyword=t(11;18) translocation, kn-keyword=t(11;18) translocation, en-keyword=Trisomy 18 kn-keyword=Trisomy 18 END start-ver=1.4 cd-journal=joma no-vol=626 cd-vols= no-issue=7999 article-no= start-page=670 end-page=677 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Oxygen-evolving photosystem II structures during S1–S2–S3 transitions en-subtitle= kn-subtitle= en-abstract= kn-abstract=Photosystem II (PSII) catalyses the oxidation of water through a four-step cycle of Si states (i = 0–4) at the Mn4CaO5 cluster1,2,3, during which an extra oxygen (O6) is incorporated at the S3 state to form a possible dioxygen4,5,6,7. Structural changes of the metal cluster and its environment during the S-state transitions have been studied on the microsecond timescale. Here we use pump-probe serial femtosecond crystallography to reveal the structural dynamics of PSII from nanoseconds to milliseconds after illumination with one flash (1F) or two flashes (2F). YZ, a tyrosine residue that connects the reaction centre P680 and the Mn4CaO5 cluster, showed structural changes on a nanosecond timescale, as did its surrounding amino acid residues and water molecules, reflecting the fast transfer of electrons and protons after flash illumination. Notably, one water molecule emerged in the vicinity of Glu189 of the D1 subunit of PSII (D1-E189), and was bound to the Ca2+ ion on a sub-microsecond timescale after 2F illumination. This water molecule disappeared later with the concomitant increase of O6, suggesting that it is the origin of O6. We also observed concerted movements of water molecules in the O1, O4 and Cl-1 channels and their surrounding amino acid residues to complete the sequence of electron transfer, proton release and substrate water delivery. These results provide crucial insights into the structural dynamics of PSII during S-state transitions as well as O–O bond formation. en-copyright= kn-copyright= en-aut-name=LiHongjie en-aut-sei=Li

G34-mutant: an individual participant data review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Diffuse hemispheric glioma, H3 G34-mutant (DHGs), is a newly categorized tumor in pediatric-type diffuse high-grade gliomas, World Health Organization grade 4, with a poor prognosis. Although prognostic factors associated with genetic abnormalities have been reported, few reports have examined the clinical presentation of DHGs, especially from the viewpoint of imaging findings. In this study, we investigated the relationship between clinical factors, including imaging findings, and prognosis in patients with DHGs.
Methods We searched Medline through the PubMed database using two search terms: “G34” and “glioma”, between 1 April 2012 and 1 July 2023. We retrieved articles that described imaging findings and overall survival (OS), and added one DHG case from our institution. We defined midline invasion (MI) as invasion to the contralateral cerebrum, brainstem, corpus callosum, thalamus, and basal ganglia on magnetic resonance imaging. The primary outcome was 12-month survival, estimated using Kaplan–Meier curves and logistic regression.
Results A total of 96 patients were included in this study. The median age was 22 years, and the proportion of male patients was 48.4%. Lesions were most frequently located in the frontal lobe (52.6%). MI was positive in 39.6% of all patients. The median OS was 14.4 months. Univariate logistic regression analysis revealed that OS was significantly worse in the MI-positive group compared with the MI-negative group. Multivariate logistic regression analysis revealed that MI was an independent prognostic factor in DHGs.
Conclusions In this study, MI-positive cases had a worse prognosis compared with MI-negative cases. en-copyright= kn-copyright= en-aut-name=KegoyaYasuhito en-aut-sei=Kegoya en-aut-mei=Yasuhito

However, how dwarf bamboos respond to and exploit these phenological gaps remain enigmatic. The light environment, soil nutrients, leaf morphology, maximum photosynthetic rate, foliage dynamics, and branching characteristics of Sasa kurilensis were examined under the canopies of Fagus crenata and Magnolia obovata. The goal was to elucidate the adaptive responses of S. kurilensis to phenological gaps in the forest understory. The findings suggest that phenological gaps under an M. obovata canopy augment the available biomass of S. kurilensis, enhancing leaf area, leaf thickness, and carbon content per unit area. However, these gaps do not appreciably influence the maximum photosynthetic rate, total leaf number, leaf lifespan, branch number, and average branch length. These findings underscore the significant impact of annually recurring phenological gaps on various aspects of S. kurilensis growth, such as its aboveground biomass, leaf morphology, and leaf biochemical characteristics. It appears that leaf morphology is a pivotal trait in the response of S. kurilensis to phenological gaps. Given the potential ubiquity of the influence of phenological gaps on dwarf bamboos across most deciduous broadleaf forests, this canopy phenomenon should not be overlooked. en-copyright= kn-copyright= en-aut-name=WuChongyang en-aut-sei=Wu en-aut-mei=Chongyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaRyota en-aut-sei=Tanaka en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiyoshiKyohei en-aut-sei=Fujiyoshi en-aut-mei=Kyohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkajiYasuaki en-aut-sei=Akaji en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HirobeMuneto en-aut-sei=Hirobe en-aut-mei=Muneto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MikiNaoko en-aut-sei=Miki en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=LiJuan en-aut-sei=Li en-aut-mei=Juan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SakamotoKeiji en-aut-sei=Sakamoto en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=GaoJian en-aut-sei=Gao en-aut-mei=Jian kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Beijing for Bamboo & Rattan Science and Technology/International Centre for Bamboo and Rattan, Key Laboratory of National Forestry and Grassland Administration kn-affil= affil-num=2 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture, Okayama University kn-affil= affil-num=4 en-affil=Biodiversity Division, National Institute for Environmental Studies kn-affil= affil-num=5 en-affil=Department of Environmental Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Department of Environmental Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Beijing for Bamboo & Rattan Science and Technology/International Centre for Bamboo and Rattan, Key Laboratory of National Forestry and Grassland Administration kn-affil= affil-num=8 en-affil=Department of Environmental Ecology, Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=9 en-affil=Beijing for Bamboo & Rattan Science and Technology/International Centre for Bamboo and Rattan, Key Laboratory of National Forestry and Grassland Administration kn-affil= en-keyword=bamboo kn-keyword=bamboo en-keyword=sasa kn-keyword=sasa en-keyword=beech forest kn-keyword=beech forest en-keyword=phenological gap kn-keyword=phenological gap en-keyword=canopy kn-keyword=canopy en-keyword=understory plant kn-keyword=understory plant en-keyword=plant morphology kn-keyword=plant morphology en-keyword=plastically kn-keyword=plastically en-keyword=leaf phenology kn-keyword=leaf phenology END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue=3 article-no= start-page=374 end-page=382 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240222 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A multi-center, prospective, clinical study to evaluate the anti-reflux efficacy of laparoscopic double-flap technique (lD-FLAP Study) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Double-flap technique (DFT) is a reconstruction procedure after proximal gastrectomy (PG). We previously reported a multi-center, retrospective study in which the incidence of reflux esophagitis (RE) (Los Angeles Classification ≥Grade B [LA-B]) 1 year after surgery was 6.0%. There have been many reports, but all of them were retrospective. Thus, a multi-center, prospective study was conducted.
Methods: Laparoscopic PG + DFT was performed for cT1N0 upper gastric cancer patients. The primary endpoint was the incidence of RE (≥LA-B) 1 year after surgery. The planned sample size was 40, based on an estimated incidence of 6.0% and an upper threshold of 20%.
Results: Forty patients were recruited, and 39, excluding one with conversion to total gastrectomy, received protocol treatment. Anastomotic leakage (Clavien–Dindo ≥Grade III) was observed in one patient (2.6%). In 38 patients, excluding one case of postoperative mortality, RE (≥LA-B) was observed in two patients (5.3%) 1 year after surgery, and the upper limit of the 95% confidence interval was 17.3%, lower than the 20% threshold. Anastomotic stricture requiring dilatation was observed in two patients (5.3%). One year after surgery, body weight change was 88.9 ± 7.0%, and PNI <40 and CONUT ≥5, indicating malnutrition, were observed in only one patient (2.6%) each. In the quality of life survey using the PGSAS-45 questionnaire, the esophageal reflux subscale score was 1.4 ± 0.6, significantly better than the public data (2.0 ± 1.0; p = 0.001).
Conclusion: Laparoscopic DFT showed anti-reflux efficacy. Taken together with the acceptable incidence of anastomotic stricture, DFT can be an option for reconstruction procedure after PG. en-copyright= kn-copyright= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IshidaMichihiro en-aut-sei=Ishida en-aut-mei=Michihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChodaYasuhiro en-aut-sei=Choda en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MuraokaAtsushi en-aut-sei=Muraoka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HatoShinji en-aut-sei=Hato en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KagawaTetsuya en-aut-sei=Kagawa en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaNorimitsu en-aut-sei=Tanaka en-aut-mei=Norimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KikuchiSatoru en-aut-sei=Kikuchi en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishizakiMasahiko en-aut-sei=Nishizaki en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Surgery, Hiroshima City Hiroshima Citizens Hospital, Hiroshima kn-affil= affil-num=3 en-affil=Department of Surgery, Hiroshima City Hiroshima Citizens Hospital, Hiroshima kn-affil= affil-num=4 en-affil=Department of Surgery, Kagawa Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Surgery, Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Surgery, Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anti-reflux surgery kn-keyword=anti-reflux surgery en-keyword=double-flap technique kn-keyword=double-flap technique en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=Kamikawa procedure kn-keyword=Kamikawa procedure en-keyword=proximal gastrectomy kn-keyword=proximal gastrectomy END start-ver=1.4 cd-journal=joma no-vol=62 cd-vols= no-issue=2 article-no= start-page=240 end-page=246 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202403 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term outcomes of lung transplantation requiring renal replacement therapy: A single-center experience en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Life-long immunosuppressive therapy after lung transplantation (LT) may lead to end-stage renal disease (ESRD), requiring renal replacement therapy (RRT). We aimed to investigate the characteristics and long-term outcomes of patients undergoing LT and requiring RRT.

Methods
This study was a single-center, retrospective cohort study. The patients were divided into the RRT (n = 15) and non-RRT (n = 170) groups. We summarized the clinical features of patients in the RRT group and compared patient characteristics, overall survival, and chronic lung allograft dysfunction (CLAD)-free survival between the two groups.

Results
The cumulative incidences of ESRD requiring RRT after LT at 5, 10, and 15 years were 0.8 %, 7.6 %, and 25.2 %, respectively. In the RRT group, all 15 patients underwent hemodialysis but not peritoneal dialysis, and two patients underwent living-donor kidney transplantation. The median follow-up period was longer in the RRT group than in the non-RRT group (P < 0.001). The CLAD-free survival and overall survival did not differ between the two groups. The 5-year survival rate even after the initiation of hemodialysis was 53.3 %, and the leading cause of death in the RRT group was infection.

Conclusions
Favorable long-term outcomes can be achieved by RRT for ESRD after LT. en-copyright= kn-copyright= en-aut-name=TomiokaYasuaki en-aut-sei=Tomioka en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ChoshiHaruki en-aut-sei=Choshi en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=IshiharaMegumi en-aut-sei=Ishihara en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtaniShinji en-aut-sei=Otani en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Lung transplantation kn-keyword=Lung transplantation en-keyword=Dialysis kn-keyword=Dialysis en-keyword=Living-donor kidney transplantation kn-keyword=Living-donor kidney transplantation en-keyword=End -stage renal disease kn-keyword=End -stage renal disease en-keyword=Renal replacement therapy kn-keyword=Renal replacement therapy END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=85 end-page=88 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Case of Idiopathic Peptic Ulcer Disease Treated Effectively with Trimebutine Maleat en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 30-year-old man with idiopathic peptic ulcer disease (IPUD) experienced repeated recurrence of ulcerative bleeding despite treatment with lansoprazole and then vonoprazan. Further evaluation suggested that the cause of the ulcer was strong contractile movements of the antrum. This prompted the co-administration of trimebutine maleate (TM) and vonoprazan to relieve the stomach contractions. TM was effective in preventing the recurrence of ulcerative bleeding, and the patient has remained in remission for 4 years. This case highlights the potential efficacy of TM in treating IPUD and the importance of considering hypercontractility as the underlying cause in cases of IPUD. en-copyright= kn-copyright= en-aut-name=MiyakeKeisuke en-aut-sei=Miyake en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanikawaTomohiro en-aut-sei=Tanikawa en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HarumaKen en-aut-sei=Haruma en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KawadaMayuko en-aut-sei=Kawada en-aut-mei=Mayuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiiKatsunori en-aut-sei=Ishii en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UrataNoriyo en-aut-sei=Urata en-aut-mei=Noriyo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishinoKen en-aut-sei=Nishino en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuehiroMitsuhiko en-aut-sei=Suehiro en-aut-mei=Mitsuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawanakaMiwa en-aut-sei=Kawanaka en-aut-mei=Miwa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ManabeNoriaki en-aut-sei=Manabe en-aut-mei=Noriaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawamotoHirofumi en-aut-sei=Kawamoto en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Post graduate clinical education center, Kawasaki Medical School General Medical Center kn-affil= affil-num=2 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=7 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=8 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=9 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= affil-num=10 en-affil=Division of Endoscopy and Ultrasonography, Department of Clinical Pathology and Laboratory Medicine, Kawasaki Medical School kn-affil= affil-num=11 en-affil=Department of General Internal Medicine 2, Kawasaki Medical School kn-affil= en-keyword=gastric ulcer kn-keyword=gastric ulcer en-keyword=idiopathic peptic ulcerative disease kn-keyword=idiopathic peptic ulcerative disease en-keyword=trimebutine maleate kn-keyword=trimebutine maleate END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=79 end-page=83 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Combined Use of Transabdominal Ultrasonography and Fecal Immunochemical Test Examinations in Ulcerative Colitis en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined the utility of the combined use of transabdominal ultrasonography (TUS) and fecal immunochemical testing (FIT) to detect mucosal inflammation, vis-a-vis the Mayo endoscopic subscore (MES), in ulcerative colitis (UC). Sixty-three UC patients who underwent TUS and FIT were retrospectively enrolled. For TUS, the colon was divided into five segments, and the bowel wall thickness was measured and evaluated. The accuracy of FIT (> 100 ng/ml) in detecting mucosal inflammation (MES>0) was 0.93, whereas that of TUS (BWT>2 mm) in each segment was 0.84-0.97. The combined use of TUS and FIT may be helpful in noninvasive treatment strategies. en-copyright= kn-copyright= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name=

implant for thumb metacarpophalangeal (MCP) joints with boutonniere deformity in patients with rheumatoid arthritis (RA). This study involved 36 thumbs of 33 RA patients with a mean follow-up period of 5.1 years (range, 2.0-13.3). Postoperatively, the mean extension was significantly increased and the mean flexion was significantly decreased (p<0.001, p<0.001, respectively), resulting in the mean arc of range of motion (ROM) shifting in the direction of extension after surgery. Implant fracture was observed in 10 thumbs (28%), and 4 of these (11%) underwent revision surgery. The survivorship with implant fracture and revision surgery as endpoints were 73.4% and 91.8% at 5 years, respectively. The preoperative arc of ROM and the postoperative flexion range of the implant-fracture group were significantly greater than those in the no-implant-fracture group (p=0.039, 0.034, respectively). These results suggest the importance of patient education and careful rehabilitation to prevent excessive flexion. Overall, the AVANTA silicone implant showed a relatively high rate of implant fracture at our institute. en-copyright= kn-copyright= en-aut-name=KanedaDaisuke en-aut-sei=Kaneda en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishidaKeiichiro en-aut-sei=Nishida en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NasuYoshihisa en-aut-sei=Nasu en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakaharaRyuichi en-aut-sei=Nakahara en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaradaRyozo en-aut-sei=Harada en-aut-mei=Ryozo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HottaYoshifumi en-aut-sei=Hotta en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaniwaShuichi en-aut-sei=Naniwa en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Locomotive Pain Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Kurashiki Sweet Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=AVANTA silicone implant kn-keyword=AVANTA silicone implant en-keyword=boutonniere deformity kn-keyword=boutonniere deformity en-keyword=implant fracture kn-keyword=implant fracture en-keyword=thumb metacarpophalangeal joint arthroplasty kn-keyword=thumb metacarpophalangeal joint arthroplasty en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=47 end-page=52 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-Term Follow-up Data of a Multi-Institutional Phase-2 Study of S-1/oxaliplatin and Bevacizumab Therapy in Patients with Advanced Colorectal Cancer: The HiSCO-02 Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Oral fluoropyrimidines (FUs) have certain advantages over intravenous FUs, such as longer intervals between outpatient visits, no requirement for central venous port (CVP) implantation, and lower incidence of neutropenia. We previously reported the efficacy of S-1/oxaliplatin (SOX) with bevacizumab therapy as a first-line treatment for advanced colorectal cancer (CRC) in a prospective phase-II multi-institutional clinical trial (HiSCO-02 study). However, our prognostic data at the time lacked a sufficient observation period. Herein, we analyze the longer-term follow-up data, focusing on the status of eventual CVP implantation via an open-label, non-randomized, multicenter study. This study enrolled 55 patients (mean age, 64 years), of whom 43 died (41 of primary cancer). The median overall survival was 22.7 months (95% CI: 20.1-34.7 months). Post-treatment regimens after failure of first-line treatment were initiated in 43 patients; CPT11-based regimens were selected in most cases, and other oral FU combinations in nine. CVP was implanted in 35 patients prior to first-line treatment; eleven of the remaining 20 patients did not require CVP implantation. In conclusion, we report here the final prognostic update of the Phase II clinical trial examining the efficacy of SOX plus bevacizumab therapy, the results of which confirm the clinical efficacy of this regimen. en-copyright= kn-copyright= en-aut-name=ShimomuraManabu en-aut-sei=Shimomura en-aut-mei=Manabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShinozakiKatsunori en-aut-sei=Shinozaki en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YanoTakuya en-aut-sei=Yano en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=AkabaneShintaro en-aut-sei=Akabane en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OhdanHideki en-aut-sei=Ohdan en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Hiroshima Surgical study group of Clinical Oncology (HiSCO) en-aut-sei=Hiroshima Surgical study group of Clinical Oncology (HiSCO) en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=2 en-affil=Division of Clinical Oncology, Hiroshima Prefectural Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=4 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=5 en-affil=Department of Gastroenterological and Transplant Surgery, Graduate School of Biomedical and Health Sciences, Hiroshima University kn-affil= affil-num=6 en-affil= kn-affil= en-keyword=metastatic colorectal cancer kn-keyword=metastatic colorectal cancer en-keyword=chemotherapy kn-keyword=chemotherapy en-keyword=S-1 kn-keyword=S-1 en-keyword=prospective phase II study kn-keyword=prospective phase II study END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=37 end-page=46 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Is Proximal Triangular Fixation Better than the Conventional Method in Adult Spinal Deformity Surgery? en-subtitle= kn-subtitle= en-abstract= kn-abstract=In adult spinal deformity (ASD) surgery, one of the key factors working to prevent proximal junctional kyphosis is the proximal anchor. The aim of this study was to compare clinical and radiographic outcomes of triangular fixation with conventional fixation as proximal anchoring techniques in ASD surgery. We retrospectively evaluated 54 patients who underwent corrective spinal fusion for ASD. Fourteen patients underwent proximal triangular fixation (Group T; average 74.6 years), and 40 patients underwent the conventional method (Group C; average 70.5 years). Clinical and radiographic outcomes were assessed using visual analogue scale (VAS) values for back pain and the Oswestry disability index (ODI). Radiographic evaluation was also collected preoperatively and postoperatively. Surgical times and intraoperative blood loss of the two groups were not significantly different (493 vs 490 min, 1,260 vs 1,173 mL). Clinical outcomes such as VAS and ODI were comparable in the two groups. Proximal junctional kyphosis in group T was slightly lower than that of group C (28.5% vs 47.5%, p=0.491). However, based on radiology, proximal screw pullout occurred significantly less frequently in the triangular fixation group than the conventional group (0.0% vs 22.5%, p=0.049). Clinical outcomes in the two groups were not significantly different. en-copyright= kn-copyright= en-aut-name=TanakaMasato en-aut-sei=Tanaka en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MeenaUmesh en-aut-sei=Meena en-aut-mei=Umesh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TaokaTakuya en-aut-sei=Taoka en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiwaraYoshihiro en-aut-sei=Fujiwara en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YokomizoDaiichiro en-aut-sei=Yokomizo en-aut-mei=Daiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=BashyalSantosh Kumar en-aut-sei=Bashyal en-aut-mei=Santosh Kumar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SakeNaveen en-aut-sei=Sake en-aut-mei=Naveen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AratakiShinya en-aut-sei=Arataki en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Okayama Rosai Hospital kn-affil= en-keyword=adult spinal deformity kn-keyword=adult spinal deformity en-keyword=proximal junctional kyphosis kn-keyword=proximal junctional kyphosis en-keyword=triangular fixation kn-keyword=triangular fixation en-keyword=minimally invasive surgery kn-keyword=minimally invasive surgery en-keyword=C arm free kn-keyword=C arm free END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=1 article-no= start-page=29 end-page=36 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202402 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Regression of Necrotic Lesions after Methotrexate Withdrawal in Patients with Methotrexate-Associated Lymphoproliferative Disorders: A Retrospective CT Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This retrospective study investigated whether necrotic lesions detected on a computed tomography (CT) scan are more regressive than non-necrotic lesions after methotrexate withdrawal in patients pathologically diagnosed with methotrexate-associated lymphoproliferative disorders (MTX-LPD). In total, 89 lesions extracted from 24 patients on CT scans were included in the analysis. All patients had been evaluated for the presence of necrosis within lesions via CT scan upon first suspicion of MTX-LPD (baseline CT scan). The percentage lesion size reduction between the baseline and initial follow-up CT scan was calculated. The association between necrosis within lesions and size changes was estimated via linear regression analyses using both crude and adjusted models. Necrosis was significantly more common in extranodal lesions (27 out of 30 lesions, 90%) than in nodal lesions (9 out of 59 lesions, 15%, p<0.001). In the crude model, the regression of necrotic lesions was 58.5% greater than that of non-necrotic lesions; the difference was statistically significant (p<0.001). Additionally, the longest diameter of necrotic lesions at the baseline CT scan was significantly greater than that of non-necrotic lesions (p<0.001). Based on the adjusted model, necrotic lesions showed 49.3% greater regression than non-necrotic lesions (p=0.017). Necrosis detected on a CT scan was found to be an independent predictor of regression after MTX withdrawal in patients with MTX-LPD. en-copyright= kn-copyright= en-aut-name=KitayamaTakahiro en-aut-sei=Kitayama en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakashi en-aut-sei=Tanaka en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KanieYuichiro en-aut-sei=Kanie en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MarukawaYohei en-aut-sei=Marukawa en-aut-mei=Yohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KojimaKatsuhide en-aut-sei=Kojima en-aut-mei=Katsuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HirakiTakao en-aut-sei=Hiraki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Radiology, Okayama City Hospital kn-affil= affil-num=3 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Radiology, Okayama Saiseikai General Hospital kn-affil= affil-num=5 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Pathology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Radiology, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=methotrexate kn-keyword=methotrexate en-keyword=lymphoproliferative disorder kn-keyword=lymphoproliferative disorder en-keyword=computed tomography kn-keyword=computed tomography en-keyword=necrosis kn-keyword=necrosis END start-ver=1.4 cd-journal=joma no-vol=113 cd-vols= no-issue= article-no= start-page=41 end-page=48 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Instant estimation of rice yield using ground-based RGB images and its potential applicability to UAV en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice (Oryza sativa L.) is one of the most important cereals, which provides 20% of the world’s food energy. However, its productivity is poorly assessed especially in the global South. Here, we provide a first study to perform a deep learning-based approach for instantaneously estimating rice yield using RGB images. During ripening stage and at harvest, over 22,000 digital images were captured vertically downwards over the rice canopy from a distance of 0.8 to 0.9m at 4,820 harvesting plots having the yield of 0.1 to 16.1 t ha-1 across six countries in Africa and Japan. A convolutional neural network (CNN) applied to these data at harvest predicted 68% variation in yield with a relative root mean square error (rRMSE) of 0.22. Even when the resolution of images was reduced (from 0.2 to 3.2cm pixel-1 of ground sampling distance), the model could predict 57% variation in yield, implying that this approach can be scaled by use of unmanned aerial vehicles. Our work offers low-cost, hands-on, and rapid approach for high throughput phenotyping, and can lead to impact assessment of productivity-enhancing interventions, detection of fields where these are needed to sustainably increase crop production. en-copyright= kn-copyright= en-aut-name=TanakaYu en-aut-sei=Tanaka en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeTomoya en-aut-sei=Watanabe en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsuraKeisuke en-aut-sei=Katsura en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujimotoYasuhiro en-aut-sei=Tsujimoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaiToshiyuki en-aut-sei=Takai en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakashi Sonam Tashi en-aut-sei=Tanaka en-aut-mei=Takashi Sonam Tashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawamuraKensuke en-aut-sei=Kawamura en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaitoHiroki en-aut-sei=Saito en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HommaKoki en-aut-sei=Homma en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MairouaSalifou Goube en-aut-sei=Mairoua en-aut-mei=Salifou Goube kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AhouantonKokou en-aut-sei=Ahouanton en-aut-mei=Kokou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IbrahimAli en-aut-sei=Ibrahim en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SenthilkumarKalimuthu en-aut-sei=Senthilkumar en-aut-mei=Kalimuthu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SemwalVimal Kumar en-aut-sei=Semwal en-aut-mei=Vimal Kumar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MatuteEduardo Jose Graterol en-aut-sei=Matute en-aut-mei=Eduardo Jose Graterol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=CorredorEdgar en-aut-sei=Corredor en-aut-mei=Edgar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=El-NamakyRaafat en-aut-sei=El-Namaky en-aut-mei=Raafat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=ManigbasNorvie en-aut-sei=Manigbas en-aut-mei=Norvie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=QuilangEduardo Jimmy P. en-aut-sei=Quilang en-aut-mei=Eduardo Jimmy P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=IwahashiYu en-aut-sei=Iwahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=NakajimaKota en-aut-sei=Nakajima en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=TakeuchiEisuke en-aut-sei=Takeuchi en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=SaitoKazuki en-aut-sei=Saito en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Mathematics, Kyushu University kn-affil= affil-num=3 en-affil=Graduate School of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=4 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=5 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=6 en-affil=Faculty of Biological Sciences, Gifu UniversityFaculty of Biological Sciences, Gifu University kn-affil= affil-num=7 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=8 en-affil=Tropical Agriculture Research Front, Japan International Research Center for Agricultural Sciences kn-affil= affil-num=9 en-affil=Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=10 en-affil=Africa Rice Center （AfricaRice） kn-affil= affil-num=11 en-affil=Africa Rice Center （AfricaRice） kn-affil= affil-num=12 en-affil=Africa Rice Center （AfricaRice）, Regional Station for the Sahel kn-affil= affil-num=13 en-affil=Africa Rice Center （AfricaRice） kn-affil= affil-num=14 en-affil=Africa Rice Center （AfricaRice）, Nigeria Station kn-affil= affil-num=15 en-affil=Latin American Fund for Irrigated Rice -

Our previous study indicated that cold PEG‒primed Eustoma seeds could maintain their germination rate and bolting rate even after being re‒dried for 30days and grown under high temperatures. The present study aimed to investigate whether prolonged storage after cold PEG‒priming affect the germination, growth, and flowering of Eustoma ‘Exe Lavender’ seedling. Seeds were initially cold‒primed with water or PEG‒6000 at ‒1.5 MPa for 5 weeks at 10°C in the dark and were then subjected to re‒drying and storage for 30, 60, 90 and 360days at 10°C. After 360days of storage, cold PEG‒primed seeds germinated earlier and more effectively than cold hydro‒primed seeds. Compared to the results after 30days of storage, plants grown from 360days exhibited similar bolting rate, days to bolting, bolting node and flowering rate, cut flower length and number of flower node. These results suggest that ‘Exe Lavender’ seeds can germinate and develop well even after 360days of storage and under high temperature conditions when subjected to cold PEG‒6000 treatment. en-copyright= kn-copyright= en-aut-name=PhanThao Thu en-aut-sei=Phan en-aut-mei=Thao Thu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FukushimaKeigo en-aut-sei=Fukushima en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaYoshiyuki en-aut-sei=Tanaka en-aut-mei=Yoshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasubaKen-ichiro en-aut-sei=Yasuba en-aut-mei=Ken-ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaYuichi en-aut-sei=Yoshida en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GotoTanjuro en-aut-sei=Goto en-aut-mei=Tanjuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Hiroshima Prefectural Technology Research Institute, Agricultural Technology Research Center kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=bolting kn-keyword=bolting en-keyword=chilling kn-keyword=chilling en-keyword=dehydrate kn-keyword=dehydrate en-keyword=long storage kn-keyword=long storage en-keyword=PEG-6000 kn-keyword=PEG-6000 END start-ver=1.4 cd-journal=joma no-vol=220 cd-vols= no-issue=2 article-no= start-page=16 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Tamyb10-D1 restores red grain color and increases grain dormancy via suppressing expression of TaLTP2.128, non-specific lipid transfer protein in wheat en-subtitle= kn-subtitle= en-abstract= kn-abstract=Grain dormancy of wheat is closely associated with grain color: red-grained lines show higher dormancy than white-grained lines. The production of red pigments is regulated by R-1, Tamyb10 gene. However, the relation between grain color and dormancy remains unknown. For this study, we generated transgenic lines which were introduced a DNA fragment containing Tamyb10-D1 gene and its a 2 kb promoter including the 5′ untranslated region into white-grained wheat. Transgenic lines showed red-grained and higher dormant traits. Contents of plant hormones and gene expression of embryos at 30 days after pollination were examined in a wild type and a transgenic line. No differences were observed in the contents of plant hormones, but several genes are differentially expressed between these lines. One differentially expressed gene, TaLTP2.128, is a member of non-specific lipid transfer proteins. It was expressed higher in white grains than in red grains. A putative amino acid sequence showed similarity to that of OsHyPRP5, which is identified as QTL controlling low-temperature germinability in rice. Expression of TaLTP2.128 was increased by grain imbibition. The increasing levels were higher not only in other white-grained lines, but also in non-dormant red-grained lines. TaLTP2.128 was expressed at a quite early stage of germination. These study findings indicate that Tamyb10 regulates dormancy release by the modification of TaLTP2.128 acting as trigger of germination. en-copyright= kn-copyright= en-aut-name=HimiEiko en-aut-sei=Himi en-aut-mei=Eiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Kurihara-YonemotoShiho en-aut-sei=Kurihara-Yonemoto en-aut-mei=Shiho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AbeFumitaka en-aut-sei=Abe en-aut-mei=Fumitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakahashiHidekazu en-aut-sei=Takahashi en-aut-mei=Hidekazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaKeisuke en-aut-sei=Tanaka en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsuuraTakakazu en-aut-sei=Matsuura en-aut-mei=Takakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MaekawaMasahiko en-aut-sei=Maekawa en-aut-mei=Masahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SasakiTakuji en-aut-sei=Sasaki en-aut-mei=Takuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=RikiishiKazuhide en-aut-sei=Rikiishi en-aut-mei=Kazuhide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Kibi International University kn-affil= affil-num=2 en-affil=Hokkaido Agricultural Research Center, National Agriculture and Food Research Organization kn-affil= affil-num=3 en-affil=Institute of Crop Science, National Agriculture and Food Research Organization kn-affil= affil-num=4 en-affil=Fukushima University kn-affil= affil-num=5 en-affil=NODAI Genome Research Center, Tokyo University of Agriculture kn-affil= affil-num=6 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=7 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= affil-num=8 en-affil=NODAI Research Institute, Tokyo University of Agriculture kn-affil= affil-num=9 en-affil=Institute of Plant Science and Resources, Okayama University kn-affil= en-keyword=Lipid transfer protein kn-keyword=Lipid transfer protein en-keyword=Pre-harvest sprouting kn-keyword=Pre-harvest sprouting en-keyword=Seed dormancy kn-keyword=Seed dormancy en-keyword=Seed germination kn-keyword=Seed germination en-keyword=Tamyb10 kn-keyword=Tamyb10 en-keyword=Wheat kn-keyword=Wheat END start-ver=1.4 cd-journal=joma no-vol=1278 cd-vols= no-issue= article-no= start-page=341723 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231016 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Determination of mass-dependent chromium isotopic compositions in geological samples by double spike-total evaporation-thermal ionization mass spectrometry (DS-TE-TIMS) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Chromium isotopes have been used to trace geochemical and cosmochemical processes in the past. However, the presence of multivalent Cr species has made it difficult to isolate Cr from geological samples, particularly for samples with a low Cr mass fraction.
Results: Here, a simple three-step ion exchange chromatography procedure is presented to separate Cr from various sample matrices, ranging from ultramafic to felsic rocks. Throughout each of the column chromatography step, 1 mL of cation exchange resin AG50W-X8 (200–400 mesh) was used as the stationary phase and oxalic acid as a chelating agent, was used in addition to the inorganic acids. This method yielded high recoveries of Cr [93 ± 8% (2SD, N = 7)] regardless of the lithology. The total procedural blank of Cr was <0.5 ng. We also developed a double spike-total evaporation-thermal ionization mass spectrometry (DS-TE-TIMS) technique that significantly reduced sample consumption to ∼20 ng of Cr per each measurement of mass-dependent 53Cr/52Cr.
Significance: This study achieved a 2SD external precision of 0.02‰ for the analysis of NIST NBS3112a and of 0.01–0.07‰ for the geological samples. This study enabled high-precision Cr isotope analysis in geological samples with various matrix and Cr compositions using relatively small sample volumes. en-copyright= kn-copyright= en-aut-name=RatnayakeDilan M. en-aut-sei=Ratnayake en-aut-mei=Dilan M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaRyoji en-aut-sei=Tanaka en-aut-mei=Ryoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NakamuraEizo en-aut-sei=Nakamura en-aut-mei=Eizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=2 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= affil-num=3 en-affil=The Pheasant Memorial Laboratory for Geochemistry and Cosmochemistry, Institute for Planetary Materials, Okayama University kn-affil= en-keyword=Cr isotopes kn-keyword=Cr isotopes en-keyword=DS-TE-TIMS kn-keyword=DS-TE-TIMS en-keyword=Cation exchange resin kn-keyword=Cation exchange resin en-keyword=Low blank kn-keyword=Low blank en-keyword=High precision kn-keyword=High precision END start-ver=1.4 cd-journal=joma no-vol=194 cd-vols= no-issue=5 article-no= start-page=e63525 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231229 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Radiological characteristics of skeletal growth in neonates and infants with achondroplasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=Achondroplasia (ACH) is the most common form of skeletal dysplasia characterized by a rhizomelic short stature. Radiological skeletal findings in pediatric and adult patients with ACH include short long bones, a relatively longer fibula compared to the tibia, a narrow lumbar interpedicular distance, and a hypoplastic iliac wing. Nonetheless, the characteristics of skeletal growth during the neonatal and infantile periods have scarcely been explored. Therefore, this retrospective study aimed to analyze the radiological skeletal growth during the neonatal and infantile periods in 41 Japanese patients with genetically confirmed ACH. The length of long bones in the upper and lower limbs and the lumbar interpedicular distances at L1 and L4 were measured. These parameters showed significant positive correlations with age. The upper segment-to-lower segment ratio in the lower limbs resembled the data of healthy controls from previous reports. The L1/L4 and fibula/tibia ratios increased with age, suggesting that some representative skeletal phenotypes of ACH were less distinct during the neonatal and infantile periods. In conclusion, for the first time, this study radiologically characterized skeletal growth during the neonatal and infantile periods of patients with genetically confirmed ACH. en-copyright= kn-copyright= en-aut-name=MiyaharaDaisuke en-aut-sei=Miyahara en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AgoYuko en-aut-sei=Ago en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HiguchiYousuke en-aut-sei=Higuchi en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YamadaKazuki en-aut-sei=Yamada en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TetsunagaTomonori en-aut-sei=Tetsunaga en-aut-mei=Tomonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaHiroyuki en-aut-sei=Tanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Orthopedics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Orthopedics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Iwakuni Clinical Center, National Hospital Organization kn-affil= affil-num=10 en-affil=Department of Pediatrics, Okayama Saiseikai General Hospital kn-affil= affil-num=11 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=bone development kn-keyword=bone development en-keyword=dwarfism kn-keyword=dwarfism en-keyword=growth kn-keyword=growth en-keyword=infant kn-keyword=infant en-keyword=radiography kn-keyword=radiography END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue= article-no= start-page=0073 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230728 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Deep Learning Enables Instant and Versatile Estimation of Rice Yield Using Ground-Based RGB Images en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rice (Oryza sativa L.) is one of the most important cereals, which provides 20% of the world’s food energy. However, its productivity is poorly assessed especially in the global South. Here, we provide a first study to perform a deep-learning-based approach for instantaneously estimating rice yield using red-green-blue images. During ripening stage and at harvest, over 22,000 digital images were captured vertically downward over the rice canopy from a distance of 0.8 to 0.9 m at 4,820 harvesting plots having the yield of 0.1 to 16.1 t·ha−1 across 6 countries in Africa and Japan. A convolutional neural network applied to these data at harvest predicted 68% variation in yield with a relative root mean square error of 0.22. The developed model successfully detected genotypic difference and impact of agronomic interventions on yield in the independent dataset. The model also demonstrated robustness against the images acquired at different shooting angles up to 30° from right angle, diverse light environments, and shooting date during late ripening stage. Even when the resolution of images was reduced (from 0.2 to 3.2 cm·pixel−1 of ground sampling distance), the model could predict 57% variation in yield, implying that this approach can be scaled by the use of unmanned aerial vehicles. Our work offers low-cost, hands-on, and rapid approach for high-throughput phenotyping and can lead to impact assessment of productivity-enhancing interventions, detection of fields where these are needed to sustainably increase crop production, and yield forecast at several weeks before harvesting. en-copyright= kn-copyright= en-aut-name=TanakaYu en-aut-sei=Tanaka en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=WatanabeTomoya en-aut-sei=Watanabe en-aut-mei=Tomoya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KatsuraKeisuke en-aut-sei=Katsura en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TsujimotoYasuhiro en-aut-sei=Tsujimoto en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TakaiToshiyuki en-aut-sei=Takai en-aut-mei=Toshiyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaTakashi Sonam Tashi en-aut-sei=Tanaka en-aut-mei=Takashi Sonam Tashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawamuraKensuke en-aut-sei=Kawamura en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SaitoHiroki en-aut-sei=Saito en-aut-mei=Hiroki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=HommaKoki en-aut-sei=Homma en-aut-mei=Koki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MairouaSalifou Goube en-aut-sei=Mairoua en-aut-mei=Salifou Goube kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=AhouantonKokou en-aut-sei=Ahouanton en-aut-mei=Kokou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=IbrahimAli en-aut-sei=Ibrahim en-aut-mei=Ali kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SenthilkumarKalimuthu en-aut-sei=Senthilkumar en-aut-mei=Kalimuthu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=SemwalVimal Kumar en-aut-sei=Semwal en-aut-mei=Vimal Kumar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MatuteEduardo Jose Graterol en-aut-sei=Matute en-aut-mei=Eduardo Jose Graterol kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=CorredorEdgar en-aut-sei=Corredor en-aut-mei=Edgar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=El-NamakyRaafat en-aut-sei=El-Namaky en-aut-mei=Raafat kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=ManigbasNorvie en-aut-sei=Manigbas en-aut-mei=Norvie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= en-aut-name=QuilangEduardo Jimmy P. en-aut-sei=Quilang en-aut-mei=Eduardo Jimmy P. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=19 ORCID= en-aut-name=IwahashiYu en-aut-sei=Iwahashi en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=20 ORCID= en-aut-name=NakajimaKota en-aut-sei=Nakajima en-aut-mei=Kota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=21 ORCID= en-aut-name=TakeuchiEisuke en-aut-sei=Takeuchi en-aut-mei=Eisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=22 ORCID= en-aut-name=SaitoKazuki en-aut-sei=Saito en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=23 ORCID= affil-num=1 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Mathematics, Kyushu University kn-affil= affil-num=3 en-affil=Graduate School of Agriculture, Tokyo University of Agriculture and Technology kn-affil= affil-num=4 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=5 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=6 en-affil=Graduate School of Environmental, Life, Natural Science and Technology, Okayama University kn-affil= affil-num=7 en-affil=Japan International Research Center for Agricultural Sciences kn-affil= affil-num=8 en-affil=Tropical Agriculture Research Front, Japan International Research Center for Agricultural Sciences kn-affil= affil-num=9 en-affil=Graduate School of Agricultural Science, Tohoku University kn-affil= affil-num=10 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=11 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=12 en-affil=Africa Rice Center (AfricaRice), Regional Station for the Sahel kn-affil= affil-num=13 en-affil=Africa Rice Center (AfricaRice) kn-affil= affil-num=14 en-affil=Africa Rice Center (AfricaRice), Nigeria Station kn-affil= affil-num=15 en-affil=Latin American Fund for Irrigated Rice -

This randomized controlled, single-blinded study was a preliminary investigation of the combined effect of nutritional support with neuromuscular electrical stimulation (NMES) on muscle strength and thickness. Healthy young adult males (median age, 21 years) were enrolled; each of their hands was randomly assigned to one of the following four groups: Placebo, Nutrition, NMES, and Nutrition + NMES. All participants received whey protein or placebo (3x/week for 6 weeks) and NMES training (3x/week for 6 weeks) on the abductor digiti minimi (ADM) muscle of either the left or right hand. ADM muscle strength and thickness were analyzed at baseline and at week 7. We analyzed 38 hands (9 Placebo, 10 Nutrition, 9 NMES, 10 Nutrition + NMES). There was significantly greater muscle strengthening in the Nutrition + NMES group compared to the Placebo group or the NMES group, but no significant difference in gain of muscle thickness. The combined intervention may be effective in improving muscle strength. Future clinical trials targeting various muscles after sports-related injuries are warranted. en-copyright= kn-copyright= en-aut-name=IkedaTomohiro en-aut-sei=Ikeda en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkamuraKazunori en-aut-sei=Okamura en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HasegawaMasaki en-aut-sei=Hasegawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KanaiShusaku en-aut-sei=Kanai en-aut-mei=Shusaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Rehabilitation Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=3 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=4 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= affil-num=5 en-affil=Department of Physical Therapy, Faculty of Health and Welfare, Prefectural University of Hiroshima kn-affil= en-keyword=whey protein kn-keyword=whey protein en-keyword=electrical stimulation kn-keyword=electrical stimulation en-keyword=muscle strength kn-keyword=muscle strength en-keyword=healthy volunteers kn-keyword=healthy volunteers END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=627 end-page=634 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Abnormal Vaginal Cytology after Total Laparoscopic Hysterectomy in Patients with Cervical Intraepithelial Neoplasia en-subtitle= kn-subtitle= en-abstract= kn-abstract=To explore the incidence of abnormal vaginal cytology after total laparoscopic hysterectomy for the treatment of cervical intraepithelial neoplasia 3, we retrospectively analyzed the medical records of patients treated at NHO Shikoku Cancer Center (Japan) in 2014-2019. The cases of 99 patients who underwent a laparoscopic (n=36) or open (n=63) hysterectomy and postoperative follow-up were examined. Abnormal vaginal cytology was detected in 13.9% (5/36) of the laparoscopic-surgery (LS) group and 14.3% (9/63) of the open-surgery (OS) group. A vaginal biopsy was performed at the physicians’ discretion; one LS patient and six OS patients were diagnosed with vaginal intraepithelial neoplasia. The cumulative incidence of abnormal vaginal cytology at 3 years post-hysterectomy was 21.4% (LS group) and 20.5% (OS group), a nonsignificant difference. A multivariate analysis showed that age > 50 years was the only independent risk factor for abnormal vaginal cytology among the covariates examined including age; body mass index; histories of vaginal delivery, abdominal surgery, and smoking; and surgical approach (hazard ratio 8.11; 95% confidence interval 1.73-37.98; p=0.01). These results suggest that the occurrence of abnormal vaginal cytology after a hysterectomy may not be influenced by the laparoscopic procedure but is associated with older age. en-copyright= kn-copyright= en-aut-name=HibinoYumi en-aut-sei=Hibino en-aut-mei=Yumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=Okazawa-SakaiMika en-aut-sei=Okazawa-Sakai en-aut-mei=Mika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokoyamaTakanori en-aut-sei=Yokoyama en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujimotoEtsuko en-aut-sei=Fujimoto en-aut-mei=Etsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkameShinichi en-aut-sei=Okame en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeramotoNorihiro en-aut-sei=Teramoto en-aut-mei=Norihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TakeharaKazuhiro en-aut-sei=Takehara en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=2 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=3 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=4 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= affil-num=6 en-affil=Department of Pathology, NHO Shikoku Cancer Center kn-affil= affil-num=7 en-affil=Department of Gynecologic Oncology, NHO Shikoku Cancer Center kn-affil= en-keyword=total laparoscopic hysterectomy kn-keyword=total laparoscopic hysterectomy en-keyword=vaginal intraepithelial neoplasia kn-keyword=vaginal intraepithelial neoplasia en-keyword=cervical intraepithelial neoplasia kn-keyword=cervical intraepithelial neoplasia en-keyword=vaginal cytology kn-keyword=vaginal cytology en-keyword=risk factor kn-keyword=risk factor END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=613 end-page=618 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Survey of Osteoarthritis of the Shoulder in Patients who Underwent Knee Arthroplasty for Knee Osteoarthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The relationship between osteoarthritis (OA) of the lower extremity and shoulder OA has not been established. This study evaluated the prevalence of shoulder OA in patients with knee OA. We collected contrast-enhanced computed tomography (CECT) images of the shoulder joints of 105 patients with knee OA that were taken 1 week after they underwent primary knee arthroplasty to check for venous thromboembolism (VTE). The images were compared with CECT images of 110 control-group patients that were taken for the purpose of differentiating VTE. Shoulder OA was present in a significantly higher percentage of patients with knee arthroplasty than controls (29% versus 15%), and the difference was particularly pronounced in patients in their 70s (33%) compared to age-matched controls (11%). Patients with knee OA often use arm support to stand up or walk due to knee joint pain and muscle weakness, which places the weight-bearing shoulder at risk of developing OA. en-copyright= kn-copyright= en-aut-name=MiyakeYoshiaki en-aut-sei=Miyake en-aut-mei=Yoshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NambaYoshifumi en-aut-sei=Namba en-aut-mei=Yoshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MitaniShigeru en-aut-sei=Mitani en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmeharaNorifumi en-aut-sei=Umehara en-aut-mei=Norifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawamotoToyohiro en-aut-sei=Kawamoto en-aut-mei=Toyohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FuruichiShuro en-aut-sei=Furuichi en-aut-mei=Shuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=3 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Bone and Joint Surgery, Kawasaki Medical School kn-affil= en-keyword=shoulder osteoarthritis kn-keyword=shoulder osteoarthritis en-keyword=knee osteoarthritis kn-keyword=knee osteoarthritis en-keyword=weight-bearing shoulder kn-keyword=weight-bearing shoulder en-keyword=knee arthroplasty kn-keyword=knee arthroplasty END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=6 article-no= start-page=595 end-page=605 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202312 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Concomitant Use of Multiple Nephrotoxins including Renal Hypoperfusion Medications Causes Vancomycin-Associated Nephrotoxicity: Combined Retrospective Analyses of Two Real-World Databases en-subtitle= kn-subtitle= en-abstract= kn-abstract=There is a growing concern about the relationship between vancomycin-associated nephrotoxicity (VAN) and concomitant use of nephrotoxins. We examined this relationship by combined retrospective analyses of two real-world databases. Initially, the FDA Adverse Event Reporting System (FAERS) was analyzed for the effects of concomitant use of one or more nephrotoxins on VAN and the types of combinations of nephrotoxins that exacerbate VAN. Next, electronic medical records (EMRs) of patients who received vancomycin (VCM) at Tokushima University Hospital between January 2006 and March 2019 were examined to confirm the FAERS analysis. An elevated reporting odds ratio (ROR) was observed with increases in the number of nephrotoxins administered (VCM + one nephrotoxin, adjusted ROR (95% confidence interval [CI]) 1.67 [1.51-1.85]; VCM + ≥2 nephrotoxins, adjusted ROR [95% CI] 1.54 [1.37-1.73]) in FAERS. EMRs analysis showed that the number of nephrotoxins was associated with higher incidences of VAN [odds ratio: 1.99; 95% CI: 1.42-2.78]. Overall, concomitant use of nephrotoxins was associated with an increased incidence of VAN, especially when at least one of those nephrotoxins was a renal hypoperfusion medication (furosemide, non-steroidal anti-inflammatory drugs, and vasopressors). The concomitant use of multiple nephrotoxins, especially including renal hypoperfusion medication, should be avoided to prevent VAN. en-copyright= kn-copyright= en-aut-name=BandoTakashi

kn-title=Review of a Series of Surveys on Adverse Reactions to the COVID-19 mRNA-1273 Vaccine at Okayama University en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents the results of a series of surveys conducted from July 2021 to March 2023 to investigate the post-vaccination adverse reactions to the mRNA-1273 (Moderna) vaccine among faculty, staff, and students at Okayama University. These studies complement the official surveys conducted by the Ministry of Health, Labour and Welfare (MHLW) and provide a more representative picture of adverse reactions in the general population including large numbers of healthy young people. Pain, swelling, redness at the injection site, fever, headache, and malaise were the main adverse reactions reported. The proportion of adverse reactions was generally higher after the second vaccination and decreased with each additional vaccination. No statistically significant differences in the adverse reactions were found for males and females and those with/without a history of allergy, but a lower proportion of fever was observed in older participants and those with underlying medical conditions. We also evaluated the association between adverse reactions and antibody titers after the third vaccination and found no significant differences in antibody levels one month after vaccination. This series of studies highlights the importance of conducting surveys in diverse populations to provide a more representative picture of post-vaccination adverse reactions during a pandemic. en-copyright= kn-copyright= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiguchiChigusa en-aut-sei=Higuchi en-aut-mei=Chigusa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Okayama University Health Service Center kn-affil= affil-num=3 en-affil=Okayama University Health Service Center kn-affil= affil-num=4 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Infectious Diseases, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=7 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=coronavirus disease 2019 kn-keyword=coronavirus disease 2019 en-keyword=adverse reactions kn-keyword=adverse reactions en-keyword=mRNA vaccine kn-keyword=mRNA vaccine en-keyword=antibody titers kn-keyword=antibody titers en-keyword=young adults kn-keyword=young adults END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue=1 article-no= start-page=e15169 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231026 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Impact of changes in skeletal muscle mass and quality during the waiting time on outcomes of lung transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The association of changes in skeletal muscle mass and quality during the waiting time with outcomes of lung transplantation (LT) remains unclear. We aimed to examine the association of changes in skeletal muscle mass and quality during the waiting time, as well as preoperative skeletal muscle mass and quality, with outcomes of LT.
Methods: This study included individuals who underwent LT from brain-dead donors. Skeletal muscle mass (cm2/m2) and quality (mean Hounsfield units [HU]) of the erector spinae muscle at the 12th thoracic level were evaluated using computed tomography. Preoperative skeletal muscle mass and quality, and their changes during the waiting time were calculated. We evaluated the associations among mechanical ventilation (MV) duration, intensive care unit (ICU) length of stay (LOS), hospital LOS, 6-minute walk distance at discharge, and 5-year survival after LT.
Results: This study included 98 patients. The median waiting time was 594.5 days (interquartile range [IQR], 355.0–913.0). The median changes in skeletal muscle mass and quality were −4.4% (IQR, −13.3–3.1) and −2.9% (IQR, −16.0–4.1), respectively. Severe low skeletal muscle mass at LT was associated with prolonged ICU LOS (B = 8.46, 95% confidence interval [CI]: .51–16.42) and hospital LOS (B = 36.00, 95% CI: 3.23–68.78). Pronounced decrease in skeletal muscle mass during the waiting time was associated with prolonged MV duration (B = 7.85, 95% CI: .89–14.81) and ICU LOS (B = 7.97, 95% CI: .83–15.10).
Conclusion: Maintaining or increasing skeletal muscle mass during the waiting time would be beneficial to improve the short-term outcomes of LT. en-copyright= kn-copyright= en-aut-name=HagiyamaAkikazu en-aut-sei=Hagiyama en-aut-mei=Akikazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KatayamaYoshimi en-aut-sei=Katayama en-aut-mei=Yoshimi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HamadaMasanori en-aut-sei=Hamada en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SendaMasuo en-aut-sei=Senda en-aut-mei=Masuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=6 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=8 en-affil=Division of Physical Medicine and Rehabilitation, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=computed tomography kn-keyword=computed tomography en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=prognosis kn-keyword=prognosis en-keyword=skeletal muscle kn-keyword=skeletal muscle en-keyword=waiting time kn-keyword=waiting time END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230925 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=生体肺移植後の長期的なドナーQOLの検討 kn-title=Donor’s long-term quality of life following living-donor lobar lung transplantation en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=FUJIIKento en-aut-sei=FUJII en-aut-mei=Kento kn-aut-name=藤井健人 kn-aut-sei=藤井 kn-aut-mei=健人 aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil=岡山大学大学院医歯薬学総合研究科 END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=05 article-no= start-page=E602 end-page=E608 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220513 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Resection depth for small colorectal polyps comparing cold snare polypectomy, hot snare polypectomy and underwater endoscopic mucosal resection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and study aims Small colorectal polyps are removed by various methods, including cold snare polypectomy (CSP), hot snare polypectomy (HSP), and underwater endoscopic mucosal resection (UEMR), but the indications for using these methods are unclear. We retrospectively assessed the efficacy of CSP, HSP, and UEMR for small polyps, focusing on the depth of the resected specimens.
Patients and methods Outpatients with non-pedunculated small polyps (endoscopically diagnosed as 6 to 9 mm), resected by two endoscopists between July 2019 and September 2020, were enrolled. We histologically evaluated the specimens resected via CSP, HSP, and UEMR. The main outcome was the containment rate of the muscularis mucosa (MM) and submucosa (SM) tissues.
Results Forty polyps resected via CSP (n = 14), HSP (n = 12), or UEMR (n = 14) were enrolled after excluding 13 polyps with resection depths that were difficult to determine. The rates of specimens containing MM and SM tissue differed significantly (57 % and 29 % for CSP, 92 % and 83 % for HSP, and 100 % and 100 % for UEMR, respectively (P = 0.005 for MM and P < 0.001 for SM tissue). Multiple logistic regression analysis showed UEMR was an independent factor relating to the containment of SM tissue. The thickness of SM tissue by CSP, HSP, and UEMR were 52 μm, 623 μm, and 1119 μm, respectively (P < 0.001). The thickness by CSP was significantly less than those by HSP and UEMR (P < 0.001, Bonferroni correction).
Conclusions UEMR could be the best method to contain SM tissue without injection. Further studies are needed to evaluate the indication of UEMR for small polyps. en-copyright= kn-copyright= en-aut-name=ToyosawaJunki en-aut-sei=Toyosawa en-aut-mei=Junki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujimotoTsuyoshi en-aut-sei=Fujimoto en-aut-mei=Tsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaShouichi en-aut-sei=Tanaka en-aut-mei=Shouichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MitsuhashiToshiharu en-aut-sei=Mitsuhashi en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Iwakuni Clinical Center kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Iwakuni Clinical Center kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol=32 cd-vols= no-issue=4 article-no= start-page=221 end-page=227 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel and recurrent COMP gene variants in five Japanese patients with pseudoachondroplasia: skeletal changes from the neonatal to infantile periods en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pseudoachondroplasia (PSACH) is an autosomal dominant skeletal dysplasia caused by pathogenic variants of cartilage oligomeric matrix protein (COMP). Clinical symptoms of PSACH are characterized by growth disturbances after the first year of life. These disturbances lead to severe short stature with short limbs, brachydactyly, scoliosis, joint laxity, joint pain since childhood, and a normal face. Epimetaphyseal dysplasia, shortened long bones, and short metacarpals and phalanges are common findings on radiological examination. Additionally, anterior tonguing of the vertebral bodies in the lateral view is an important finding in childhood because it is specific to PSACH and normalizes with age. Here, we report five Japanese patients with PSACH, with one recurrent (p.Cys351Tyr) and four novel heterozygous pathogenic COMP variants (p.Asp437Tyr, p.Asp446Gly, p.Asp507Tyr, and p.Asp518Val). These five pathogenic variants were located in the calcium-binding type 3 (T3) repeats. In four of the novel variants, the affected amino acid was aspartic acid, which is abundant in each of the eight T3 repeats. We describe the radiological findings of these five patients. We also retrospectively analyzed the sequential changes in the vertebral body and epimetaphysis of the long bones from the neonatal to infantile periods in a patient with PSACH and congenital heart disease. en-copyright= kn-copyright= en-aut-name=HasegawaKosei en-aut-sei=Hasegawa en-aut-mei=Kosei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=FutagawaNatsuko en-aut-sei=Futagawa en-aut-mei=Natsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=AgoYuko en-aut-sei=Ago en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyaharaHiroyuki en-aut-sei=Miyahara en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaradaDaisuke en-aut-sei=Harada en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyazawaMari en-aut-sei=Miyazawa en-aut-mei=Mari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimotoJunko en-aut-sei=Yoshimoto en-aut-mei=Junko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BabaKenji en-aut-sei=Baba en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoriwakeTadashi en-aut-sei=Moriwake en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TanakaHiroyuki en-aut-sei=Tanaka en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pediatrics, JCHO Osaka Hospital kn-affil= affil-num=6 en-affil=Department of Pediatrics, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pediatrics, Iwakuni Clinical Center, National Hospital Organization kn-affil= affil-num=10 en-affil=Department of Pediatrics, Okayama Saiseikai General Hospital kn-affil= affil-num=11 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=infant kn-keyword=infant en-keyword=skeleton kn-keyword=skeleton en-keyword=spine kn-keyword=spine en-keyword=cartilage kn-keyword=cartilage en-keyword=growth kn-keyword=growth END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=1 article-no= start-page=24 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Connective tissue mast cells store and release noradrenaline en-subtitle= kn-subtitle= en-abstract= kn-abstract=Mast cells are present in mucosal and connective tissues throughout the body. They synthesize and release a wide variety of bioactive molecules, such as histamine, proteases, and cytokines. In this study, we found that a population of connective tissue mast cells (CTMCs) stores and releases noradrenaline, originating from sympathetic nerves. Noradrenaline-storing cells, not neuronal fibers, were predominantly identified in the connective tissues of the skin, mammary gland, gastrointestinal tract, bronchus, thymus, and pancreas in wild-type mice but were absent in mast cell-deficient W-sash c-kit mutant KitW-sh/W-sh mice. In vitro studies using bone marrow-derived mast cells revealed that extracellular noradrenaline was taken up but not synthesized. Upon ionomycin stimulation, noradrenaline was released. Electron microscopy analyses further suggested that noradrenaline is stored in and released from the secretory granules of mast cells. Finally, we found that noradrenaline-storing CTMCs express organic cation transporter 3 (Oct3), which is also known as an extraneuronal monoamine transporter, SLC22A3. Our findings indicate that mast cells may play a role in regulating noradrenaline concentration by storing and releasing it in somatic tissues. en-copyright= kn-copyright= en-aut-name=OtaniYusuke en-aut-sei=Otani en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshikawaSoichiro en-aut-sei=Yoshikawa en-aut-mei=Soichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagaoKei en-aut-sei=Nagao en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimuraAtsushi en-aut-sei=Fujimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Breast and Endocrinological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cellular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Mast cells kn-keyword=Mast cells en-keyword=Connective tissue mast cells kn-keyword=Connective tissue mast cells en-keyword=Noradrenaline kn-keyword=Noradrenaline en-keyword=Immunoelectron microscopy kn-keyword=Immunoelectron microscopy en-keyword=SLC22A3 kn-keyword=SLC22A3 END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue= article-no= start-page=101990 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic nutritional index is a prognostic factor for patients with gastric cancer and esophagogastric junction cancer undergoing proximal gastrectomy with esophagogastrostomy by the double-flap technique: A secondary analysis of the rD-FLAP study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose: Although proximal gastrectomy (PG) is commonly used in patients with upper gastric cancer (GC) and esophagogastric junction (EGJ) cancer, long-term prognostic factors in these patients are poorly understood. The double-flap technique (DFT) is an esophagogastrostomy with anti-reflux mechanism after PG; we previously conducted a multicenter retrospective study (rD-FLAP) to evaluate the short-term outcomes of DFT reconstruction. Here, we evaluated the long-term prognostic factors in patients with upper GC and EGJ cancer.
Methods: The study was conducted as a secondary analysis of the rD-FLAP Study, which enrolled patients who underwent PG with DFT reconstruction, irrespective of disease type, between January 1996 and December 2015.
Results: A total of 509 GC and EGJ cancer patients were enrolled. Univariate and multivariate analyses of overall survival demonstrated that a preoperative prognostic nutritional index (PNI) < 45 (p < 0.001, hazard ratio [HR]: 3.59, 95% confidential interval [CI]: 1.93–6.67) was an independent poor prognostic factor alongside pathological T factor ([pT] ≥2) (p = 0.010, HR: 2.29, 95% CI: 1.22–4.30) and pathological N factor ([pN] ≥1) (p = 0.001, HR: 3.27, 95% CI: 1.66–6.46). In patients with preoperative PNI ≥45, PNI change (<90%) at 1-year follow-up (p = 0.019, HR: 2.54, 95%CI: 1.16–5.54) was an independent poor prognostic factor, for which operation time (≥300 min) and blood loss (≥200 mL) were independent risk factors. No independent prognostic factors were identified in patients with preoperative PNI <45.
Conclusions: PNI is a prognostic factor in upper GC and EGJ cancer patients. Preoperative nutritional enhancement and postoperative nutritional maintenance are important for prognostic improvement in these patients. en-copyright= kn-copyright= en-aut-name=KakiuchiYoshihiko en-aut-sei=Kakiuchi en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KurodaShinji en-aut-sei=Kuroda en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ChodaYasuhiro en-aut-sei=Choda en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=OtsukaShinya en-aut-sei=Otsuka en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeyamaSatoshi en-aut-sei=Ueyama en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaNorimitsu en-aut-sei=Tanaka en-aut-mei=Norimitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MuraokaAtsushi en-aut-sei=Muraoka en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HatoShinji en-aut-sei=Hato en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KamikawaYasuaki en-aut-sei=Kamikawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=FujiwaraToshiyoshi en-aut-sei=Fujiwara en-aut-mei=Toshiyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Surgery, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=4 en-affil=Department of Surgery, Fukuyama Medical Center kn-affil= affil-num=5 en-affil=Department of Surgery, Mihara Red Cross Hospital kn-affil= affil-num=6 en-affil=Department of Surgery, Kagawa Prefectural Central Hospital kn-affil= affil-num=7 en-affil=Department of Surgery, Kagawa Rosai Hospital kn-affil= affil-num=8 en-affil=Department of Surgery, Shikoku Cancer Center kn-affil= affil-num=9 en-affil=Department of Surgery, Matsuda Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Double -flap technique kn-keyword=Double -flap technique en-keyword=Gastric cancer kn-keyword=Gastric cancer en-keyword=Prognostic factor kn-keyword=Prognostic factor en-keyword=Prognostic nutritional index kn-keyword=Prognostic nutritional index en-keyword=Proximal gastrectomy kn-keyword=Proximal gastrectomy END start-ver=1.4 cd-journal=joma no-vol=155 cd-vols= no-issue= article-no= start-page=105797 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Ruxolitinib altered IFN-β induced necroptosis of human dental pulp stem cells during osteoblast differentiation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: This study aimed to evaluate the role of ruxolitinib in the interferon beta (IFN-β) mediated osteoblast differentiation using human dental pulp stem cells (hDPSCs).
Design: hDPSCs from five deciduous teeth of healthy patients were stimulated by adding human recombinant IFN-β protein (1 or 2 ng/ml) to the osteogenic differentiation induction medium. Substrate formation was determined using Alizarin Red staining, calcium concentration, and osteoblast marker expression levels. Ruxolitinib was used to inhibit the Janus kinase/signal transducers and activators of transcription (JAK-STAT) pathway. Apoptosis was detected using terminal deoxynucleotidyl nick-end labeling (TUNEL) staining, and necroptosis was detected using propidium iodide staining and phosphorylated mixed lineage kinase domain-like protein (pMLKL) expression.
Results: In the IFN-β-treated group, substrate formation was inhibited by a reduction in alkaline phosphatase (ALP) expression in a concentration-dependent manner. Although the proliferation potency was unchanged between the IFN-β-treated and control groups, the cell number was significantly reduced in the experimental group. TUNEL-positive cell number was not significantly different; however, the protein level of necroptosis markers, interleukin-6 (IL-6) and pMLKL were significantly increased in the substrate formation. Cell number and ALP expression level were improved in the group administered ruxolitinib, a JAK-STAT inhibitor. Additionally, ruxolitinib significantly suppressed IL-6 and pMLKL levels.
Conclusion: Ruxolitinib interfered with the IFN-β-mediated necroptosis and osteogenic differentiation via the JAK-STAT pathway. en-copyright= kn-copyright= en-aut-name=TanakaAtsuko en-aut-sei=Tanaka en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HayanoSatoru en-aut-sei=Hayano en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NagataMasayo en-aut-sei=Nagata en-aut-mei=Masayo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KosamiTakahiro en-aut-sei=Kosami en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=WangZiyi en-aut-sei=Wang en-aut-mei=Ziyi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KamiokaHiroshi en-aut-sei=Kamioka en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Orthodontics, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Orthodontics, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Type-I interferon kn-keyword=Type-I interferon en-keyword=Janus kinase/signal transducers and activators of transcription pathway kn-keyword=Janus kinase/signal transducers and activators of transcription pathway en-keyword=Osteoblast kn-keyword=Osteoblast en-keyword=Necroptosis kn-keyword=Necroptosis en-keyword=Singleton-Merten Syndrome kn-keyword=Singleton-Merten Syndrome END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=545 end-page=552 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic Manifestations and Clinical Characteristics of Localized Gastric Light-Chain Amyloidosis en-subtitle= kn-subtitle= en-abstract= kn-abstract=To determine the endoscopic and clinical features of localized gastric amyloid light-chain (AL) amyloidosis, we retrospectively examined the characteristics of nine patients (eight men and one woman) encountered by the hospitals in our network. Lesions were predominantly flat and depressed with surface vascular dilatation (n=5); others were characterized by subepithelial lesions (n=2), mucosal color change (n=1), and a mass-like morphology with swollen mucosal folds (n=1). Colonoscopy (n=7), video capsule enteroscopy (n=2), serum (n=5) and urine immunoelectrophoresis (n=4), and bone marrow examination (n=3) were performed to exclude involvement of organs other than the stomach. As treatment for gastric lesions of AL amyloidosis, one patient each underwent endoscopic submucosal dissection (n=1) and argon plasma coagulation (n=1), while the remaining seven patients underwent no specific treatment. During a mean follow-up of 4.2 years, one patient died 3.2 years after diagnosis, but the cause of death, which occurred in another hospital, was unknown. The remaining eight patients were alive at the last visit. In conclusion, although localized gastric AL amyloidosis can show various macroscopic features on esophagogastroduodenoscopy, flat, depressed lesions with vascular dilatation on the surface are predominant. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaShouichi en-aut-sei=Tanaka en-aut-mei=Shouichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NishimuraMamoru en-aut-sei=Nishimura en-aut-mei=Mamoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TsuzukiTakao en-aut-sei=Tsuzuki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyaharaKoji en-aut-sei=Miyahara en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NegishiShin en-aut-sei=Negishi en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OhyaShogen en-aut-sei=Ohya en-aut-mei=Shogen kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=3 en-affil=Department of Gastroenterology, National Hospital Organization Fukuyama Medical Center kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Kawaguchi Medical Clinic kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=gastric lesion kn-keyword=gastric lesion en-keyword=amyloidosis kn-keyword=amyloidosis en-keyword=light chain kn-keyword=light chain END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=527 end-page=536 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinical Characteristics of Retroperitoneal Fibrosis Patients at a Tertiary Hospital in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Retroperitoneal fibrosis (RPF) is a rare cause of hydronephrosis and progressive renal dysfunction with unidentified origin. RPF is categorized into idiopathic RPF with/without immunoglobulin G4 (IgG4)-related disease (IgG4-RD), and secondary RPF. Identifying the underlying cause is challenging and often associated with delayed diagnosis or therapeutic interventions. We investigated RPF’s clinical characteristics based on different etiologies and factors that may help distinguish the underlying causes. We analyzed the cases of 49 patients with RPF that was radiographically diagnosed at our institution (2008-2022). The cohort was 77.6% males; 75.5% had idiopathic RPF and 24.5% had secondary RPF. Among the idiopathic patients, 54.1% had IgG4-RD. The patients were likely to have abdominal pain, lower back pain/lumbago, and constitutional symptoms including generalized fatigue and fever. The idiopathic patients were likely to have higher serum IgG4 and IgG levels and lower serum C3 levels compared to secondary RPF. The IgG4-RPF patients were likely to have higher serum IgG4 levels and lower serum C-reactive protein, ferritin, and C3 levels compared to the idiopathic RPF patients without IgG4-RD. These findings might reflect underlying systemic inflammatory responses. Comprehensive laboratory testing, including serum inflammatory markers and immunological panels, is recommended for radiologically diagnosed RPF patients. en-copyright= kn-copyright= en-aut-name=AndoMiho en-aut-sei=Ando en-aut-mei=Miho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanayamaYoshihisa en-aut-sei=Hanayama en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimuraYoshito en-aut-sei=Nishimura en-aut-mei=Yoshito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HagiyaHideharu en-aut-sei=Hagiya en-aut-mei=Hideharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=retroperitoneal fibrosis kn-keyword=retroperitoneal fibrosis en-keyword=IgG4-related disease kn-keyword=IgG4-related disease en-keyword=malignancy kn-keyword=malignancy END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=511 end-page=516 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Associations among Preoperative Malnutrition, Muscle Loss, and Postoperative Walking Ability in Intertrochanteric Fractures: A Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Sarcopenia and malnutrition are increasing in older adults and are reported risk factors for functional impairment after hip fracture surgery. This study aimed to investigate the associations between skeletal muscle mass loss, malnutrition, and postoperative walking ability in patients with hip fracture. We retrospectively reviewed patients who underwent intertrochanteric fracture surgery at our institute. The psoas muscle index, controlling nutritional status score, and functional ambulation category (FAC) were used to evaluate skeletal muscle mass, nutritional status, and walking ability, respectively. Six months after surgery, walking ability was assessed as either “gait disturbance” or “independent gait”. Multivariate binomial logistic regression analysis, with skeletal muscle mass, nutritional status, and other factors, was used to predict the risk of being assigned to the gait disturbance group. This study included 95 patients (mean age, 85.2 years; 70 women). Sixty-six patients had low skeletal muscle mass, 35 suffered from malnutrition, and 28 had both. Malnutrition and low skeletal muscle mass were significantly associated with postoperative gait disturbance (FAC < 3). Preoperative low skeletal muscle mass and malnutrition were risk factors for postoperative poor walking ability. Further preventive interventions focusing on skeletal muscle mass and nutritional status are required. en-copyright= kn-copyright= en-aut-name=SatoKohei en-aut-sei=Sato en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsujiHironori en-aut-sei=Tsuji en-aut-mei=Hironori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YorimitsuMasanori en-aut-sei=Yorimitsu en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UeharaTakenori en-aut-sei=Uehara en-aut-mei=Takenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OkazakiYuki en-aut-sei=Okazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakaoShinichiro en-aut-sei=Takao en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HataToshiaki en-aut-sei=Hata en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FukuokaShiro en-aut-sei=Fukuoka en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NodaTomoyuki en-aut-sei=Noda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KandaHideyuki en-aut-sei=Kanda en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OzakiToshifumi en-aut-sei=Ozaki en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Orthopedic Surgery, Japanese Red Cross Okayama Hospital kn-affil= affil-num=3 en-affil=Department of Orthopedic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Emergency, Critical Care, and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Okayama Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Orthopedic Surgery, Kawasaki Medical School, General Medical Center kn-affil= affil-num=10 en-affil=Department of Public Health, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Orthopedic Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sarcopenia kn-keyword=sarcopenia en-keyword=nutrition kn-keyword=nutrition en-keyword=geriatric hip fracture kn-keyword=geriatric hip fracture en-keyword=psoas muscle index kn-keyword=psoas muscle index en-keyword=controlling nutritional status score kn-keyword=controlling nutritional status score END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=499 end-page=509 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Neurological Analysis Based on the Terminal End of the Spinal Cord and the Narrowest Level of Injured Spine in Thoracolumbar Spinal Injuries en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study aimed to clarify neurological differences among the epiconus, conus medullaris, and cauda equina syndromes. Eighty-seven patients who underwent surgery for acute thoracolumbar spinal injuries were assessed. We defined the epiconus as the region from the terminal end of the spinal cord to the proximal 1.0 to 2.25 vertebral bodies, the conus medullaris as the region proximal to < 1.0 vertebral bodies, and the cauda equina as the distal part of the nerve roots originating from the spinal cord. On the basis of the distance from the terminal end of the spinal cord to the narrowest level of the spinal canal, the narrowest levels were ordered as follows: the epiconus followed by the conus medullaris and cauda equina. The narrowest levels were the epiconus in 22 patients, conus medullaris in 37 patients, and cauda equina in 25 patients. On admission, significantly more patients had a narrowed epiconus of Frankel grades A-C than a narrowed cauda equina. At the final follow-up, there were no significant differences in neurological recovery among those with epiconus, conus medullaris, or cauda equina syndrome. Anatomically classifying the narrowest lesion is useful for clarifying the differences and similarities among these three syndromes. en-copyright= kn-copyright= en-aut-name=HatakeyamaYuji en-aut-sei=Hatakeyama en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HongoMichio en-aut-sei=Hongo en-aut-mei=Michio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KidoTadato en-aut-sei=Kido en-aut-mei=Tadato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UrayamaMasakazu en-aut-sei=Urayama en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KasukawaYuji en-aut-sei=Kasukawa en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SasakiHiroshi en-aut-sei=Sasaki en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AizawaToshiaki en-aut-sei=Aizawa en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KudoDaisuke en-aut-sei=Kudo en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KimuraRyota en-aut-sei=Kimura en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OnoYuichi en-aut-sei=Ono en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KasamaFumihito en-aut-sei=Kasama en-aut-mei=Fumihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MiyakoshiNaohisa en-aut-sei=Miyakoshi en-aut-mei=Naohisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Akita Red Cross Hospital kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Akita Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Ogachi Central Hospital kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Orthopaedic Surgery, Noshiro Kousei Medical Center kn-affil= affil-num=7 en-affil=Department of Orthopaedic Surgery, Kitaakita Municipal Hospital kn-affil= affil-num=8 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Orthopaedic Surgery, Akita Red Cross Hospital kn-affil= affil-num=11 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Orthopaedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=thoracolumbar spinal injury kn-keyword=thoracolumbar spinal injury en-keyword=terminal end of spinal cord kn-keyword=terminal end of spinal cord en-keyword=conus medullaris kn-keyword=conus medullaris en-keyword=epiconus syndrome kn-keyword=epiconus syndrome en-keyword=cauda equina syndrome kn-keyword=cauda equina syndrome END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=479 end-page=490 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Childcare and Child Development in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=For decades, the notion has persisted in developed countries that exclusive care by the mothers is best for the development of children up to 3 years of age. To examine the veracity of this “myth of the first three years” in Japan, we examined the effects of childcare facility use for children younger than 3 years on their development using the cohorts of the Longitudinal Survey of Newborns in the 21st Century conducted in Japan. Of the 47,015 respondents to the survey, we studied the children of 5,508 mothers with university/professional education to evaluate the relationships between primary early (< 2.5 years) childcare providers during weekday daytime hours and specific development indices for the ages of 2.5, 5.5, and 8 years. At the age of 2.5 and 5.5 years, children attending childcare facilities were judged as having more advanced developmental behaviors by their parents, such as being able to compose a two-word sentence (adjusted odds ratio [aOR]: 0.22) or to express emotions (aOR: 0.81), compared with those cared for by mothers. However, at the age of 8 years, children who attended childcare facilities as infants < 2.5 years showed more aggressive behavior in interrupting people (aOR: 1.20) and causing disturbances in public (aOR: 1.26) than those cared for by mothers (after adjustment for numerous child and parental factors). Although these results are generally consistent with previous studies, issues potentially involved with problem behavior such as quality of childcare require further investigation, as does the case of children of mothers with more modest educational attainment. en-copyright= kn-copyright= en-aut-name=MurataAkiko en-aut-sei=Murata en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=“myth of the first three years” kn-keyword=“myth of the first three years” en-keyword=childcare kn-keyword=childcare en-keyword=child development kn-keyword=child development en-keyword=problem behavior kn-keyword=problem behavior en-keyword=educational attainment kn-keyword=educational attainment END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=471 end-page=478 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low Patient Weight and Long Intubation Time Are Key Factors for Pain during Colonoscopy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the clinical usefulness of colonoscopy has been established, the procedure remains painful for many patients. This study was designed to clarify the factors predicting colonoscopy-related pain. We evaluated 283 consecutive patients who completed a first-ever, total colonoscopy without sedatives or analgesics. The severity of pain symptoms was evaluated by a numeric rating scale (NRS) in a questionnaire immediately after the colonoscopy. Patient backgrounds and endoscopic findings were analyzed to evaluate their association with pain. Out of 283 patients, 53 scored their pain 0-1 on the NRS while 48 scored it 6-10. We defined the colonoscopies of the former and latter patients as painless and painful, respectively, and compared the two. Multivariate analyses revealed that low body weight (OR 4.95, 95%CI 1.89-12.99) and longer intubation time (OR 3.63, 95%CI 1.46-9.03) were significant risk factors for painful colonoscopy. To identify factors contributing to the increased intubation time, we divided subjects into short- and long-intubation-time groups based on a median insertion time of 7 min. Older age (OR 2.28, 95%CI 1.31-3.98), previous abdominal surgery (OR 1.93, 95%CI 1.13-3.32) and findings of invasive cancer (OR 10.90, 95%CI 1.34-88.90) were significant factors for longer intubation time. en-copyright= kn-copyright= en-aut-name=OkaShohei en-aut-sei=Oka en-aut-mei=Shohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HaradaKeita en-aut-sei=Harada en-aut-mei=Keita kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YasutomiEriko en-aut-sei=Yasutomi en-aut-mei=Eriko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IgawaShoko en-aut-sei=Igawa en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OhmoriMasayasu en-aut-sei=Ohmori en-aut-mei=Masayasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HiraiMami en-aut-sei=Hirai en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=InokuchiToshihiro en-aut-sei=Inokuchi en-aut-mei=Toshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KinugasaHideaki en-aut-sei=Kinugasa en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=TakaharaMasahiro en-aut-sei=Takahara en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=HiraokaSakiko en-aut-sei=Hiraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Departments of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=colonoscopy kn-keyword=colonoscopy en-keyword=colonoscopy-related pain kn-keyword=colonoscopy-related pain en-keyword=comfortable colonoscopy kn-keyword=comfortable colonoscopy END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=5 article-no= start-page=443 end-page=449 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202310 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Does Participation in the Setouchi Triennale Foster Social Capital? : A Cross-Sectional Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=This study examined whether participation in an art project was associated with higher social capital (SC). We conducted a questionnaire survey from November 2021 to March 2022 among residents aged 20 years or older of Naoshima, an island in Kagawa Prefecture, Japan. Before the survey, the Setouchi Triennale had been held on Naoshima four times, starting in 2010. We calculated propensity scores for Triennale participation and performed propensity score matching. We then compared cognitive and structural SC by Triennale participation and found significant differences, respectively. We adopted a conditional ordered logistic regression analysis with propensity score matching for cognitive or structural SC, and found adjusted odd ratios of 2.913 (95%CI, 1.846-4.596) for cognitive SC and 4.535 (95%CI, 2.839-7.244) for structural SC. Our findings suggest that Triennale participation enhanced the cognitive aspect of SC while also building structural SC. en-copyright= kn-copyright= en-aut-name=MiyajiChikara en-aut-sei=Miyaji en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoNaomi en-aut-sei=Matsumoto en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=AooKen en-aut-sei=Aoo en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NishitaYosuke en-aut-sei=Nishita en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TsuriMasao en-aut-sei=Tsuri en-aut-mei=Masao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil= affil-num=7 en-affil=Faculty of Economics, Musashi University kn-affil= affil-num=8 en-affil=Department of Epidemiology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=social capital kn-keyword=social capital en-keyword=art project kn-keyword=art project en-keyword=propensity score matching kn-keyword=propensity score matching END start-ver=1.4 cd-journal=joma no-vol=30 cd-vols= no-issue=13 article-no= start-page=8727 end-page=8734 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230901 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic Impact of Tumor-Infiltrating Lymphocytes, Tertiary Lymphoid Structures, and Neutrophil-to-Lymphocyte Ratio in Pulmonary Metastases from Uterine Leiomyosarcoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background　The presence of tumor-infiltrating lymphocytes (TILs) and tertiary lymphoid structures (TLSs) in tumor tissue has been related to the prognosis in various malignancies. Meanwhile, neutrophil-to-lymphocyte ratio (NLR) as a systemic inflammation marker also has been associated with the prognosis in them. However, few reports have investigated the relationship between pulmonary metastases from sarcoma and these biomarkers.
Methods　We retrospectively recruited 102 patients undergoing metastasectomy for pulmonary metastases from uterine leiomyosarcoma at Okayama University Hospital from January 2006 to December 2019. TILs and TLSs were evaluated by immunohistochemical staining of surgically resected specimens of pulmonary metastases using anti-CD3/CD8/CD103/Foxp3/CD20 antibodies. NLR was calculated from the blood examination immediately before the most recent pulmonary metastasectomy. We elucidated the relationship between the prognosis and these factors. Because we considered that the status of tumor tissue and systemic inflammation were equally valuable, we also assessed the impact of the combination of TILs or TLSs and NLR on the prognosis.
Results　As for TILs, CD3-positive cells and CD8-positive cells were correlated with the prognosis. The prognosis was significantly better in patients with CD3-high group, CD8-high group, TLSs-high group, and NLR-low group, respectively. The prognosis of CD8-high/NLR-low group and TLSs-high/NLR-low group was significantly better than that of CD8-low/NLR-high group and TLSs-low/NLR-high group, respectively.
Conclusions　CD3-positive TILs, CD8-positive TILs, TLSs, and NLR are correlated with the prognosis, respectively. The combination of CD8-positive TILs or TLSs and NLR may be the indicators to predict the prognosis of patients with pulmonary metastases from uterine leiomyosarcoma. en-copyright= kn-copyright=

in the Literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 41-year-old woman showed a palpable mass at the superonasal orbital edge on the right side. Magnetic resonance imaging demonstrated a lobulated fluid-containing tubular mass which extended anteriorly to posteriorly along the medial orbital wall, nasal to the eyeball. She was followed once a year for 8 years until the age of 49 years when she decided to undergo surgical resection because of the enlarged mass. The lobulated large mass was resected and the pathology showed sparsely distributed spindle cells, positive for CD34, in alcian blue-positive mucous substances, indicative of myxoma. Postoperative magnetic resonance imaging showed residual lobulated tubular mass along the optic nerve on the medial side and superior to the eyeball. The residual orbital mass showed stable structure with more evident connection with the ethmoid sinus lesion, suggestive of the ethmoid origin, in 12 years until the age of 61 years. In the review of 20 patients with orbital myxomas in the literature, in addition to this case, roughly classified locations in the orbit were retrobulbar in 8 patients, on the lateral side of the orbit in 4, on the superior side in 6, on the medial side in 1 (this patient), and in the orbit with no specific description in 2. In pathological examinations, immunohistochemistry was not done in 8 patients, done but all negative in 2, and positive in 11 patients: nerve sheath myxoma was diagnosed in 3 patients based on positive S100 staining. Orbital myxoma is rare but considered in differential diagnosis of orbital masses. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= en-keyword=myxoma kn-keyword=myxoma en-keyword=orbital kn-keyword=orbital en-keyword=CD34 kn-keyword=CD34 en-keyword=ethmoid sinus kn-keyword=ethmoid sinus en-keyword=literature review kn-keyword=literature review END start-ver=1.4 cd-journal=joma no-vol=2 cd-vols= no-issue=1 article-no= start-page=e83 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20211209 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fever and electrocoagulation syndrome after colorectal endoscopic submucosal dissection for patients with immunosuppressants and steroids en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Transient fever and electrocoagulation syndrome after colorectal endoscopic submucosal dissection (ESD) remain a challenge. The aim of this study was to assess the risk factors of post-ESD fever and post-ESD coagulation syndrome (PECS), focusing on the involvement of immunosuppressive drugs and steroids (IM).
Methods: This retrospective analysis included 510 patients who underwent colorectal ESD at Okayama University Hospital from 2015 to 2020. The incidence rate, clinical outcome, and factors associated with post-ESD fever and PECS were investigated.
Results: Post-ESD fever and PECS occurred in 63 patients (12.4%) and 43 patients (8.4%), respectively. In multivariate analysis, the American Society of Anesthesiologists Physical Status ≥3, the use of immunosuppressants or prednisolone ≥5mg (IM group), and injury to muscle layer/perforation were significantly associated with post-ESD fever. In PECS, IM group, tumors located on the right side, treatment time ≥60 min, injury to the muscle layer, and multiple lesions were independent risk factors. Both post-ESD fever and PECS improved conservatively in the IM group, and no serious complication was observed.
Conclusions: The use of IM was a risk factor for both post-ESD fever and PECS. However, there were no serious complications in colorectal ESD for patients taking IM. en-copyright= kn-copyright= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name=

≤ 6-mm non-ampullary duodenal low-grade adenomas en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and study aims　Because the endoscopic treatment for non-ampullary duodenal adenoma (NADA) has a non-negligible risk of adverse events (AEs), a safe and easy treatment for NADA is desirable. This was a multicenter prospective trial evaluating the efficacy and safety of cold forceps polypectomy (CFP) for diminutive NADAs.
Patients and methods　This study was prospectively conducted at six general hospitals and one university hospital. The inclusion criteria were histologic and endoscopic diagnosis of low-grade NADA measuring ≤ 6 mm. A second endoscopy was scheduled for 1 month after CFP. After confirmation of the success of CFP, 6-month and 12-month surveillance endoscopies were scheduled. The primary endpoint was the endoscopic and histologic disease disappearance rates at the 12-month endoscopy.
Results　Thirty-nine lesions from 38 patients were prospectively included. Median tumor size at enrollment was 5 mm (range 3–6 mm). There were four cases of remnant lesions at the second endoscopy, and the lesion disappearance rate of single CFP was 89.7 % (35 /39; 95 % confidence interval (CI), 76.9 %–97.9 %). In three cases, complete removal of the lesion was achieved with a single re-CFP, but one case required four repeat CFPs. The lesion disappearance rate at 12-month endoscopy was 97.4 % (38 /39; 95 %CI, 86.8 %–99.5 %). During the follow-up period, no AEs related to CFP were observed.
Conclusions　CFP for NADA ≤ 6 mm was safe and effective in this study. This common endoscopic method to remove lesions may be an option for treatment of diminutive NADAs. en-copyright= kn-copyright= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HoriiJoichiro en-aut-sei=Horii en-aut-mei=Joichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakenakaRyuta en-aut-sei=Takenaka en-aut-mei=Ryuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NakagawaHiroyuki en-aut-sei=Nakagawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuedaKazuhiro en-aut-sei=Matsueda en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsuzukiTakao en-aut-sei=Tsuzuki en-aut-mei=Takao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KitaMasahide en-aut-sei=Kita en-aut-mei=Masahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamasakiYasushi en-aut-sei=Yamasaki en-aut-mei=Yasushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KawaharaYoshiro en-aut-sei=Kawahara en-aut-mei=Yoshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=TomodaJun en-aut-sei=Tomoda en-aut-mei=Jun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology, Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Internal Medicine, Tsuyama Central Hospital kn-affil= affil-num=4 en-affil=Department of Endoscopy, Hiroshima City Hiroshima Citizens Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=6 en-affil=Department of Internal Medicine, Himeji Red Cross Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama City Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Practical Gastrointestinal Endoscopy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Internal Medicine, Akaiwa Medical Association Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2005 dt-pub=20051231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=特発性手根管症候群におけるポータブル型神経伝導時間測定器の有用性の検討 kn-title=Accuracy of a portable electroneurometer for measuring distal motor latency en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=TanakaHideki en-aut-sei=Tanaka en-aut-mei=Hideki kn-aut-name=田中日出樹 kn-aut-sei=田中 kn-aut-mei=日出樹 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学 END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=429 end-page=431 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=An Unusual Presentation of Chest Pain and Laryngeal Discomfort in a Pregnant Woman: A Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Intramural esophageal dissection (IED), characterized by bleeding into the submucosal space, leads to mucosal separation and dissection. The most prevalent symptoms are sudden chest or retrosternal pain, hematemesis, and dysphagia. Therefore, acute coronary syndrome and aortic dissection are among its most notable differential diagnoses. A 31-year-old pregnant woman presented with acute chest pain, laryngeal discomfort, and hematemesis. Emergency esophagogastroscopy revealed longitudinal mucosal dissection (upper esophagus to esophagogastric junction). The patient was successfully treated by avoiding the ingestion of solid foods. Clinicians should consider a diagnosis of IED for pregnant patients with acute chest pain, especially if hematemesis is present. en-copyright= kn-copyright= en-aut-name=SasanamiMisa en-aut-sei=Sasanami en-aut-mei=Misa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IidaAtsuyoshi en-aut-sei=Iida en-aut-mei=Atsuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiraiRyousuke en-aut-sei=Hirai en-aut-mei=Ryousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ObaraTakashi en-aut-sei=Obara en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YumotoTetsuya en-aut-sei=Yumoto en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NaitoHiromichi en-aut-sei=Naito en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NakaoAtsunori en-aut-sei=Nakao en-aut-mei=Atsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Emergency, Critical Care and Disaster Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=chest pain kn-keyword=chest pain en-keyword=dysphagia kn-keyword=dysphagia en-keyword=esophageal dissection kn-keyword=esophageal dissection en-keyword=hematemesis kn-keyword=hematemesis END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=423 end-page=427 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Acute Coronary Spasm Following Pelvic Fracture, Bleeding, and Shock in a Trauma Patient en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of a patient with severe pelvic fracture who showed concurrent ST elevation on electrocardiogram. A 70-year-old man incurred an unstable pelvic fracture from a motorcycle accident. On admission, he was hemodynamically unstable, and massive transfusion and noradrenaline were administered immediately. Although ST elevation was present in leads II, III, aVF, V5, and V6, cardiac function was preserved; thus, trans-arterial embolization and external fixation for pelvic fracture were given priority. Four days after the injury, he suffered a cardiac arrest, and coronary angiography revealed that the cause of ST elevation and cardiac arrest was coronary vasospasm. Physicians should be aware that pain-related stress and platelet activation as well as use of noradrenaline in severe trauma cases can induce coronary vasospasm. en-copyright= kn-copyright= en-aut-name=YamakawaYasuaki en-aut-sei=Yamakawa en-aut-mei=Yasuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyashitaKohei en-aut-sei=Miyashita en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorizaneAtsushi en-aut-sei=Morizane en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakeuchiMasato en-aut-sei=Takeuchi en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KawashimaYuta en-aut-sei=Kawashima en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugimuraTomoko en-aut-sei=Sugimura en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaisakaYuichi en-aut-sei=Saisaka en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Emergency and Critical Care Center, Kochi Health Sciences Center kn-affil= affil-num=2 en-affil=Emergency and Critical Care Center, Kochi Health Sciences Center kn-affil= affil-num=3 en-affil=Emergency and Critical Care Center, Kochi Health Sciences Center kn-affil= affil-num=4 en-affil=Department of Cardiology, Kochi Health Sciences Center kn-affil= affil-num=5 en-affil=Department of Radiology, Kochi Health Sciences Center kn-affil= affil-num=6 en-affil=Emergency and Critical Care Center, Kochi Health Sciences Center kn-affil= affil-num=7 en-affil=Emergency and Critical Care Center, Kochi Health Sciences Center kn-affil= en-keyword=coronary spasm angina kn-keyword=coronary spasm angina en-keyword=noradrenaline kn-keyword=noradrenaline en-keyword=severe trauma kn-keyword=severe trauma en-keyword=ST elevation kn-keyword=ST elevation en-keyword=treatment strategy kn-keyword=treatment strategy END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=387 end-page=394 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Association between Radon Hot Spring Bathing and Health Conditions: A Cross-Sectional Study in Misasa, Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=No epidemiological studies have examined the health effects of daily bathing in radon hot springs. In this cross-sectional study, we investigated the associations between radon hot spring bathing and health conditions. The target population was 5,250 adults ≥ 20 years old in the town of Misasa, Japan. We collected information about the participants’ bathing habits and alleviation of a variety of disease symptoms, and their self-rated health (SRH). Unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals (CI) were calculated. In both the adjusted and unadjusted models of hypertension, significant associations between the > 1×/week hot spring bathing and the alleviation of hypertension symptoms were observed compared to the group whose hot spring bathing was <1×/week: adjusted model, OR 5.40 (95%CI: 1.98-14.74); unadjusted model, 3.67 (1.50-8.99) and for gastroenteritis: adjusted model, 9.18 (1.15-72.96); unadjusted model, 7.62 (1.59-36.49). Compared to the no-bathing group, higher SRH was significantly associated with both bathing < 1×/week: unadjusted model, 2.27 (1.53-3.37) and > 1×/week: adjusted model, 1.91 (1.15-3.19). These findings suggest that bathing in radon hot springs is associated with higher SRH and the alleviation of hypertension and gastroenteritis. en-copyright= kn-copyright= en-aut-name=KataokaTakahiro en-aut-sei=Kataoka en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HabuHiroshi en-aut-sei=Habu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaAyumi en-aut-sei=Tanaka en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NaoeShota en-aut-sei=Naoe en-aut-mei=Shota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurakamiKaito en-aut-sei=Murakami en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujimotoYuki en-aut-sei=Fujimoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YukimineRyohei en-aut-sei=Yukimine en-aut-mei=Ryohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakaoSoshi en-aut-sei=Takao en-aut-mei=Soshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MitsunobuFumihiro en-aut-sei=Mitsunobu en-aut-mei=Fumihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=YamaokaKiyonori en-aut-sei=Yamaoka en-aut-mei=Kiyonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=2 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=4 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=5 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=6 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=7 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= affil-num=8 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Longevity and Social Medicine (Geriatrics), Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Radiological Technology, Okayama University Graduate School of Health Sciences kn-affil= en-keyword=radon hot spring kn-keyword=radon hot spring en-keyword=bathing habit kn-keyword=bathing habit en-keyword=self-rated health kn-keyword=self-rated health en-keyword=cross-section study kn-keyword=cross-section study END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=11676 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230719 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effectiveness of deep learning classifiers in histopathological diagnosis of oral squamous cell carcinoma by pathologists en-subtitle= kn-subtitle= en-abstract= kn-abstract=The study aims to identify histological classifiers from histopathological images of oral squamous cell carcinoma using convolutional neural network (CNN) deep learning models and shows how the results can improve diagnosis. Histopathological samples of oral squamous cell carcinoma were prepared by oral pathologists. Images were divided into tiles on a virtual slide, and labels (squamous cell carcinoma, normal, and others) were applied. VGG16 and ResNet50 with the optimizers stochastic gradient descent with momentum and spectral angle mapper (SAM) were used, with and without a learning rate scheduler. The conditions for achieving good CNN performances were identified by examining performance metrics. We used ROCAUC to statistically evaluate diagnostic performance improvement of six oral pathologists using the results from the selected CNN model for assisted diagnosis. VGG16 with SAM showed the best performance, with accuracy = 0.8622 and AUC = 0.9602. The diagnostic performances of the oral pathologists statistically significantly improved when the diagnostic results of the deep learning model were used as supplementary diagnoses (p-value = 0.031). By considering the learning results of deep learning model classifiers, the diagnostic accuracy of pathologists can be improved. This study contributes to the application of highly reliable deep learning models for oral pathological diagnosis. en-copyright= kn-copyright= en-aut-name=SukegawaShintaro en-aut-sei=Sukegawa en-aut-mei=Shintaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnoSawako en-aut-sei=Ono en-aut-mei=Sawako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaFuta en-aut-sei=Tanaka en-aut-mei=Futa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InoueYuta en-aut-sei=Inoue en-aut-mei=Yuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HaraTakeshi en-aut-sei=Hara en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshiiKazumasa en-aut-sei=Yoshii en-aut-mei=Kazumasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakanoKeisuke en-aut-sei=Nakano en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakabatakeKiyofumi en-aut-sei=Takabatake en-aut-mei=Kiyofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawaiHotaka en-aut-sei=Kawai en-aut-mei=Hotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KatsumitsuShimada en-aut-sei=Katsumitsu en-aut-mei=Shimada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NakaiFumi en-aut-sei=Nakai en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakaiYasuhiro en-aut-sei=Nakai en-aut-mei=Yasuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=MiyazakiRyo en-aut-sei=Miyazaki en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MurakamiSatoshi en-aut-sei=Murakami en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NagatsukaHitoshi en-aut-sei=Nagatsuka en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=MiyakeMinoru en-aut-sei=Miyake en-aut-mei=Minoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Pathology, Kagawa Prefectural Central Hospital kn-affil= affil-num=3 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=4 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=5 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=6 en-affil=Department of Electrical, Electronic and Computer Engineering, Faculty of Engineering, Gifu University kn-affil= affil-num=7 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=8 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=9 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=10 en-affil=Department of Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=11 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=12 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=13 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=14 en-affil=Department of Oral Pathology, Graduate School of Oral Medicine, Matsumoto Dental University kn-affil= affil-num=15 en-affil=Department of Oral Pathology and Medicine, Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=16 en-affil=Department of Oral and Maxillofacial Surgery, Kagawa University Faculty of Medicine kn-affil= END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=7 article-no= start-page=e18241 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202307 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Expression and clinicopathological characteristics of PDX1, PTF1A, and SALL4 in large and small ducts of ectopic pancreas located in gastro-duodenum and jejunum en-subtitle= kn-subtitle= en-abstract= kn-abstract=An ectopic pancreas is defined as pancreatic tissue outside its normal location, anatomically separated from the pancreas.
　The transcription factor pancreas/duodenum homeobox protein 1 (PDX1) is involved in maintaining the pancreas and functions in early pancreatic development, beta cell differentiation, and endocrine non beta cells. Pancreatic transcription factor 1 subunit alpha (PTF1A) affects exocrine cell formation and regulation of acinar cell identity, and is expressed in exocrine cells as a transcription factor. The depletion of SALL4 disrupts self-renewal and induces differentiation.
　To clarify which of PDX1, PTF1A, or SALL4 determines the difference in Heinrich's classification, we examined the localization and number of positive cells. We analyzed the differential expression of PDX1, PTF1A, and SALL4 in large and small ducts in ectopic pancreas by immunohistochemistry. Results showed that the number of PTF1A-positive cells in large ducts was more widespread in type I than in type II in the gastro-duodenum, and more SALL4-positive cells were noticed in large ducts than in small ducts in the gastro-duodenum of type II. Our results revealed that PTF1A might promote exocrine differentiation in developing the pancreatic tissues, and that those with widespread expression differentiate into exocrine cells. en-copyright= kn-copyright= en-aut-name=ChenMengxi en-aut-sei=Chen en-aut-mei=Mengxi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IgawaTakuro en-aut-sei=Igawa en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HanYanyan en-aut-sei=Han en-aut-mei=Yanyan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=PengFangli en-aut-sei=Peng en-aut-mei=Fangli kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=JinZaishun en-aut-sei=Jin en-aut-mei=Zaishun kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshinoTadashi en-aut-sei=Yoshino en-aut-mei=Tadashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Pathology, Mudanjiang Medical University kn-affil= affil-num=7 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=PDX1 kn-keyword=PDX1 en-keyword=PTF1A kn-keyword=PTF1A en-keyword=SALL4 kn-keyword=SALL4 en-keyword=Ectopic pancreas kn-keyword=Ectopic pancreas en-keyword=Gastro-duodenum kn-keyword=Gastro-duodenum en-keyword=Jejunum kn-keyword=Jejunum END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=359 end-page=364 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Changes in TRPV1 Receptor, CGRP, and BDNF Expression in Rat Dorsal Root Ganglion with Resiniferatoxin-Induced Neuropathic Pain: Modulation by Pulsed Radiofrequency Applied to the Sciatic Nerve en-subtitle= kn-subtitle= en-abstract= kn-abstract=Pulsed radiofrequency (PRF) is a safe method of treating neuropathic pain by generating intermittent electric fields at the needle tip. Resiniferatoxin (RTX) is an ultrapotent agonist of transient receptor potential vanilloid subtype-1 (TRPV1) receptors. We investigated the mechanism of PRF using a rat model of RTX-induced neuropathic pain. After administering RTX intraperitoneally, PRF was applied to the right sciatic nerve. We observed the changes in TRPV1, calcitonin gene-related peptide (CGRP), and brain-derived neurotrophic factor (BDNF) in the dorsal root ganglia by western blotting. Expressions of TRPV1 and CGRP were significantly lower in the contralateral (RTX-treated, PRF-untreated) tissue than in control rats (p<0.0001 and p<0.0001, respectively) and the ipsilateral tissues (p<0.0001 and p<0.0001, respectively). BDNF levels were significantly higher in the contralateral tissues than in the control rats (p<0.0001) and the ipsilateral tissues (p<0.0001). These results suggest that, while TRPV1 and CGRP are decreased by RTX-induced neuronal damage, increased BDNF levels result in pain development. PRF may promote recovery from neuronal damage with concomitant restoration of TRPV1 and CGRP, and exert its analgesic effect by reversing BDNF increase. Further research is required to understand the role of TRPV1 and CGRP restoration in improving mechanical allodynia. en-copyright= kn-copyright= en-aut-name=KoshidaTomohiro en-aut-sei=Koshida en-aut-mei=Tomohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MarutaToyoaki en-aut-sei=Maruta en-aut-mei=Toyoaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaNobuhiko en-aut-sei=Tanaka en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HidakaKotaro en-aut-sei=Hidaka en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KurogiMio en-aut-sei=Kurogi en-aut-mei=Mio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NemotoTakayuki en-aut-sei=Nemoto en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YanagitaToshihiko en-aut-sei=Yanagita en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TakeyaRyu en-aut-sei=Takeya en-aut-mei=Ryu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsuneyoshiIsao en-aut-sei=Tsuneyoshi en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=3 en-affil=Tanaka homecare clinic kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=6 en-affil=Department of Pharmacology, Faculty of Medicine, Fukuoka University kn-affil= affil-num=7 en-affil=Department of Clinical Pharmacology, School of Nursing, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=8 en-affil=Department of Pharmacology, Faculty of Medicine, University of Miyazaki kn-affil= affil-num=9 en-affil=Department of Anesthesiology and Pain Clinic, Faculty of Medicine, University of Miyazaki kn-affil= en-keyword=pulsed radiofrequency kn-keyword=pulsed radiofrequency en-keyword=resiniferatoxin kn-keyword=resiniferatoxin en-keyword=transient receptor potential vanilloid subtype-1 (TRPV1) kn-keyword=transient receptor potential vanilloid subtype-1 (TRPV1) en-keyword=calcitonin gene-related peptide (CGRP) kn-keyword=calcitonin gene-related peptide (CGRP) en-keyword=brain-derived neurotrophic factor (BDNF) kn-keyword=brain-derived neurotrophic factor (BDNF) END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=347 end-page=357 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Feasibility of Flow Cytometry Analysis of Gastrointestinal Tract-Residing Lymphocytes in Hematopoietic Stem Cell Transplant Recipients en-subtitle= kn-subtitle= en-abstract= kn-abstract=The feasibility of lymphocyte isolation and flow cytometry using a single endoscopic biopsy specimen from the gastrointestinal tract of patients who have undergone hematopoietic stem cell transplantation has not been investigated. We acquired 51 endoscopic biopsy specimens from the gastrointestinal tract of 35 patients. We divided the flow cytometry samples into two groups: group A, successful lymphocyte isolation (n=24), and group B, incomplete isolation (n=27). We compared the backgrounds of the samples between the groups to reveal crucial elements in the successful isolation of lymphocytes residing in the gastrointestinal tract. Comparison between the groups revealed lymphocyte isolation success rates differed between biopsy sites. Isolation was most successful in samples from the duodenum (8/9, 88.9%), followed by the ileum (4/8, 50.0%), large intestine (4/11, 36.4%), and stomach (8/23, 34.8%). Tacrolimus was used more frequently in group B (92.6%) than in group A (62.5%) (p=0.015). Logistic regression analysis revealed that isolation from the duodenum or ileum was a significant factor for successful isolation, while tacrolimus use was not statistically significant. In conclusion, the duodenum and ileum are more suitable sites than the stomach and colorectum for acquiring samples for flow cytometry. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KondoTakumi en-aut-sei=Kondo en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsuokaKen-ichi en-aut-sei=Matsuoka en-aut-mei=Ken-ichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiTakahide en-aut-sei=Takahashi en-aut-mei=Takahide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HirabataAraki en-aut-sei=Hirabata en-aut-mei=Araki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MaedaYoshinobu en-aut-sei=Maeda en-aut-mei=Yoshinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Division of Medical Support, Okayama University Hospital kn-affil= affil-num=7 en-affil=Division of Medical Support, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Hematology and Oncology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=flow cytometry kn-keyword=flow cytometry en-keyword=stem cell transplantation kn-keyword=stem cell transplantation en-keyword=transplantation-associated microangiopathy kn-keyword=transplantation-associated microangiopathy END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=4 article-no= start-page=341 end-page=345 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202308 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Biological Roles of Hepatitis B Viral X Protein in the Viral Replication and Hepatocarcinogenesis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Hepatitis B virus is a pathogenic virus that infects 300 million people worldwide and causes chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. Hepatitis B virus encodes four proteins. Among them, the HBx protein plays a central role in the HBV pathogenesis. Because the HBx protein is considered to play a central role in the induction of viral replication and hepatocarcinogenesis, the regulation of its function could be a key factor in the development of new interventions against hepatitis B. In this review, HBx protein-related viral replication and hepatocarcinogenesis mechanisms are described, with a focus on the recently reported viral replication mechanisms related to degradation of the Smc5/6 protein complex. We also discuss our recent discovery of a compound that inhibits HBx protein-induced degradation of the Smc5/6 protein complex, and that exerts inhibitory effects on both viral replication and hepatocarcinogenesis. Finally, prospects for future research on the HBx protein are described. en-copyright= kn-copyright= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Academic Field of Medicine, Density and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=HBx kn-keyword=HBx en-keyword=Smc5/6 kn-keyword=Smc5/6 en-keyword=DDB1 kn-keyword=DDB1 en-keyword=nitazoxianide kn-keyword=nitazoxianide en-keyword=DNA repair kn-keyword=DNA repair END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=7 article-no= start-page=5263 end-page=5275 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230621 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Update in Molecular Aspects and Diagnosis of Autoimmune Gastritis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Recent studies have advanced our understanding of the pathophysiology of autoimmune gastritis, particularly its molecular aspects. The most noteworthy recent advancement lies in the identification of several candidate genes implicated in the pathogenesis of pernicious anemia through genome-wide association studies. These genes include PTPN22, PNPT1, HLA-DQB1, and IL2RA. Recent studies have also directed attention towards other genes such as ATP4A, ATP4B, AIRE, SLC26A7, SLC26A9, and BACH2 polymorphism. In-depth investigations have been conducted on lymphocytes and cytokines, including T helper 17 cells, interleukin (IL)-17A, IL-17E, IL-17F, IL-21, IL-19, tumor necrosis factor-α, IL-15, transforming growth factor-β1, IL-13, and diminished levels of IL-27. Animal studies have explored the involvement of roseolovirus and H. pylori in relation to the onset of the disease and the process of carcinogenesis, respectively. Recent studies have comprehensively examined the involvement of autoantibodies, serum pepsinogen, and esophagogastroduodenoscopy in the diagnosis of autoimmune gastritis. The current focus lies on individuals demonstrating atypical presentations of the disease, including those diagnosed in childhood, those yielding negative results for autoantibodies, and those lacking the typical endoscopic characteristics of mucosal atrophy. Here, we discuss the recent developments in this field, focusing on genetic predisposition, epigenetic modifications, lymphocytes, cytokines, oxidative stress, infectious agents, proteins, microRNAs, autoantibodies, serum pepsinogen, gastrin, esophagogastroduodenoscopy and microscopic findings, and the risk of gastric neoplasm. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=autoimmune gastritis kn-keyword=autoimmune gastritis en-keyword=esophagogastroduodenoscopy kn-keyword=esophagogastroduodenoscopy en-keyword=genetic predisposition kn-keyword=genetic predisposition en-keyword=lymphocyte kn-keyword=lymphocyte en-keyword=oxidative stress kn-keyword=oxidative stress END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=3 article-no= start-page=1067 end-page=1083 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230723 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Analysis of genetic diversity and population structure in Cambodian melon landraces using molecular markers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Genetic diversity of Cambodian melons was evaluated by the analysis of 12 random amplified polymorphic DNA (RAPD) and 7 simple sequence repeat (SSR) markers using 62 accessions of melon landraces and compared with 231 accessions from other areas for genetic characterization of Cambodian melons. Among 62 accessions, 56 accessions were morphologically classified as small-seed type with seed lengths shorter than 9 mm, as in the horticultural groups Conomon and Makuwa. Gene diversity of Cambodian melons was 0.228, which was equivalent to those of the groups Conomon and Makuwa and smaller than those of Vietnamese and Central Asian landraces. A phylogenetic tree constructed from a genetic distance matrix classified 293 accessions into three major clusters. Small-seed type accessions from East and Southeast Asia formed clusters I and II, which were distantly related with cluster III consisting of large-seed type melon from other areas. All Cambodian melons belonged to cluster I (except three accessions) along with those from Thailand, Myanmar, Yunnan (China), and Vietnam (“Dua thom” in the northwest), thus indicating genetic similarity in these areas. In addition, the Cambodian melons were not differentiated among geographical populations. Conomon and Makuwa were classified into cluster II, together with melon groups from the plains of Vietnam. The presence of two groups of melons in Southeast Asia was also indicated by population structure and principal coordinate analysis. These results indicated a close genetic relationship between Cambodia and the neighboring countries, thus suggesting that Cambodian melons are not directly related to the establishment of Conomon and Makuwa. en-copyright= kn-copyright= en-aut-name=NazninPervin Mst en-aut-sei=Naznin en-aut-mei=Pervin Mst kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ImohOdirichi Nnennaya en-aut-sei=Imoh en-aut-mei=Odirichi Nnennaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaKatsunori en-aut-sei=Tanaka en-aut-mei=Katsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SreynechOuch en-aut-sei=Sreynech en-aut-mei=Ouch kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ShigitaGentaro en-aut-sei=Shigita en-aut-mei=Gentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SopheaYon en-aut-sei=Sophea en-aut-mei=Yon kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SophanySakhan en-aut-sei=Sophany en-aut-mei=Sakhan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MakaraOuk en-aut-sei=Makara en-aut-mei=Ouk kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TomookaNorihiko en-aut-sei=Tomooka en-aut-mei=Norihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishidaHidetaka en-aut-sei=Nishida en-aut-mei=Hidetaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KatoKenji en-aut-sei=Kato en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Faculty of Agriculture and Life Science, Hirosaki University kn-affil= affil-num=4 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=5 en-affil=Department of Life Science Systems, Technical University of Munich kn-affil= affil-num=6 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=7 en-affil=Cambodian Agricultural Research and Development Institute kn-affil= affil-num=8 en-affil=Plant Breeder, Retired Director of the Cambodian Agricultural Research and Development Institute kn-affil= affil-num=9 en-affil=Research Center of Genetic Resources, National Agriculture and Food Research Organization (NARO) kn-affil= affil-num=10 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=11 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=12 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Cambodia kn-keyword=Cambodia en-keyword=Conomon kn-keyword=Conomon en-keyword=Cucumis melo kn-keyword=Cucumis melo en-keyword=Genetic diversity kn-keyword=Genetic diversity en-keyword=Landraces kn-keyword=Landraces en-keyword=RAPD kn-keyword=RAPD en-keyword=SSR kn-keyword=SSR END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=269 end-page=277 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=2023 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Elucidation of genetic variation and population structure of melon genetic resources in the NARO Genebank, and construction of the World Melon Core Collection en-subtitle= kn-subtitle= en-abstract= kn-abstract=Numerous genetic resources of major crops have been introduced from around the world and deposited in Japanese National Agriculture and Food Research Organization (NARO) Genebank. Understanding their genetic variation and selecting a representative subset (“core collection”) are essential for optimal management and efficient use of genetic resources. In this study, we conducted genotyping-by-sequencing (GBS) to characterize the genetic relationships and population structure in 755 accessions of melon genetic resources. The GBS identified 39,324 single-nucleotide polymorphisms (SNPs) that are distributed throughout the melon genome with high density (one SNP/10.6 kb). The phylogenetic relationships and population structure inferred using this SNP dataset are highly associated with the cytoplasm type and geographical origin. Our results strongly support the recent hypothesis that cultivated melon was established in Africa and India through multiple independent domestication events. Finally, we constructed a World Melon Core Collection that covers at least 82% of the genetic diversity and has a wide range of geographical origins and fruit morphology. The genome-wide SNP dataset, phylogenetic relationships, population structure, and the core collection provided in this study should largely contribute to genetic research, breeding, and genetic resource preservation in melon. en-copyright= kn-copyright= en-aut-name=ShigitaGentaro en-aut-sei=Shigita en-aut-mei=Gentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DungTran Phuong en-aut-sei=Dung en-aut-mei=Tran Phuong kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=PervinMst.

This study investigated the relationship between the %LAA and the development of CLAD after bilateral lung transplantation (LT).
Methods: We conducted a single-center retrospective study of 75 recipients who underwent bilateral LT; the recipients were divided into a CLAD group (n = 30) and a non-CLAD group (n = 45). The %LAA was calculated using CT and compared between the two groups from 4 years before to 4 years after the diagnosis of CLAD. The relationships between the %LAA and the percent baseline values of the pulmonary function test parameters were also calculated.
Results: The %LAA was significantly higher in the CLAD group than in the non-CLAD group from 2 years before to 2 years after the diagnosis of CLAD (P < .05). In particular, patients with bronchiolitis obliterans syndrome (BOS) exhibited significant differences even from 4 years before to 4 years after diagnosis (P < .05). Significant negative correlations between the %LAA and the percent baseline values of the forced expiratory volume in 1 s (r = −.36, P = .0031), the forced vital capacity (r = −.27, P = .027), and the total lung capacity (r = −.40, P < .001) were seen at the time of CLAD diagnosis.
Conclusion: The %LAA on CT was associated with the development of CLAD and appears to have the potential to predict CLAD, especially BOS, after bilateral LT. en-copyright= kn-copyright= en-aut-name=KuboYujiro en-aut-sei=Kubo en-aut-mei=Yujiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiotaniToshio en-aut-sei=Shiotani en-aut-mei=Toshio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HashimotoKohei en-aut-sei=Hashimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ShienKazuhiko en-aut-sei=Shien en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= en-keyword=bronchiolitis obliterans syndrome kn-keyword=bronchiolitis obliterans syndrome en-keyword=chronic lung allograft dysfunction kn-keyword=chronic lung allograft dysfunction en-keyword=computed tomography kn-keyword=computed tomography en-keyword=lung transplantation kn-keyword=lung transplantation en-keyword=restrictive allograft syndrome kn-keyword=restrictive allograft syndrome END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=5 article-no= start-page=e39466 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230525 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagenous Colitis in a Patient With Gastric Cancer Who Underwent Chemotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Herein, we present a case of collagenous colitis in a patient who underwent chemotherapy for gastric cancer, comprising five cycles of S-1 plus oxaliplatin and trastuzumab, followed by five cycles of paclitaxel and ramucirumab and seven cycles of nivolumab. The subsequent initiation of trastuzumab deruxtecan chemotherapy led to the development of grade 3 diarrhea after the second cycle of treatment. Collagenous colitis was diagnosed via colonoscopy and biopsy. The patient's diarrhea improved following the cessation of lansoprazole. This case highlights the importance of considering collagenous colitis as a differential diagnosis, in addition to chemotherapy-induced colitis and immune-related adverse event (irAE) colitis, in patients with similar clinical presentations. en-copyright= kn-copyright= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KagawaShunsuke en-aut-sei=Kagawa en-aut-mei=Shunsuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=InooShoko en-aut-sei=Inoo en-aut-mei=Shoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Pathology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=immune checkpoint inhibitor kn-keyword=immune checkpoint inhibitor en-keyword=chemotherapy-induced diarrhea kn-keyword=chemotherapy-induced diarrhea en-keyword=immune-related adverse event colitis kn-keyword=immune-related adverse event colitis en-keyword=colonoscopy kn-keyword=colonoscopy en-keyword=collagenous colitis kn-keyword=collagenous colitis END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue=9 article-no= start-page=5182 end-page=5194 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230627 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Long-term management and outcome of lung transplantation in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=The long-term survival after lung transplantation (LT) is favorable in Japan. However, longterm survivors after LT are subject to late complications, including chronic lung allograft dysfunction (CLAD), malignancy, infection, and chronic kidney disease (CKD) because of the need for lifelong immunosuppression. The rates of single cadaveric LT (CLT) and living-donor lobar LT (LDLLT) are higher than that of bilateral CLT in Japan. Here, we will describe the management of late complications and long-term outcome after LT in Japan. Attention should be paid to not only the phenotype of CLAD but also the difference in CLAD after CLT and after LDLLT as well as the timing of lung re-transplantation for advanced CLAD, especially after single CLT. Since post-transplant lymphoproliferative disorder is the most common malignancy after LT, infection monitoring for infection-related malignancies and appropriate screening are keys to the early diagnosis and treatment of malignancy after LT. The long-term management of infection after LT is also important, especially with regard to community-acquired pathogens, Aspergillus, and cytomegalovirus. When providing long-term care after LT, physicians should be aware of CKD and the timing of renal replacement therapy in cases with severe CKD. The widespread use of computed tomography and dialysis in Japan are beneficial for long-term survivors of LT. The similar survival outcomes of single CLT and LDLLT, compared with bilateral CLT, might contribute to improved long-term survival in Japan. Pulmonologists are encouraged to become further involved in long-term management after LT in Japan. en-copyright= kn-copyright= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsubaraKei en-aut-sei=Matsubara en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TanakaShin en-aut-sei=Tanaka en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IshiharaMegumi en-aut-sei=Ishihara en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery and Organ Transplant Center, Okayama University Hospital kn-affil= en-keyword=Lung transplantation kn-keyword=Lung transplantation en-keyword=chronic lung allograft dysfunction kn-keyword=chronic lung allograft dysfunction en-keyword=infection kn-keyword=infection en-keyword=malignan kn-keyword=malignan en-keyword=cychronic kidney kn-keyword=cychronic kidney en-keyword=disease kn-keyword=disease END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230705 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bilateral Lacrimal Gland Mantle Cell Lymphoma in 11-Year Follow-Up: Case Report and Review of 48 Cases With Ocular Adnexal Presentation in the Literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 63-year-old woman, with 11-year history of breast cancer, showed bilateral lacrimal gland enlargement on magnetic resonance imaging. Gallium-67 scintigraphy, as the standard at that time in 2004, demonstrated abnormally high uptake only in bilateral lacrimal glands. The lacrimal glands were extirpated and the pathological diagnosis was mantle cell lymphoma (MCL). She underwent bilateral orbital radiation, based on no uptake of gallium-67 in other sites of the body. In a month, bone marrow biopsy revealed the infiltration with MCL, positive for cyclin D1. She showed hepatic lymphadenopathy and splenomegaly, and so received 2 cycles of alternating Hyper-CVAD therapy and high-dose methotrexate with cytarabine, combined with rituximab, in 2 months, leading to complete remission. She underwent autologous peripheral blood stem cell transplantation and was well until the age of 68 years when she showed a recurrent intratracheal submucosal lesion of lymphoma and underwent one course of reduced-dose CHOP combined with rituximab. Next year, the left rib resection revealed the metastasis of breast adenocarcinoma, leading to daily oral letrozole. Further 2 years later, computed tomographic scan demonstrated multiple submucosal nodular lesions in the trachea and bronchi, together with cervical and supraclavicular lymphadenopathy, and intratracheal lesion biopsy and bone marrow biopsy proved the involvement with MCL. She underwent 2 courses of bendamustine and rituximab, resulting in complete remission but died of metastatic breast cancer at the age of 74 years. Clinical features in 48 previous cases with ocular adnexal MCL in the literature were summarized in this study. en-copyright= kn-copyright= en-aut-name=MatsuoToshihiko en-aut-sei=Matsuo en-aut-mei=Toshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TanakaTakehiro en-aut-sei=Tanaka en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaKazuya en-aut-sei=Okada en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=NotoharaKenji en-aut-sei=Notohara en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FujiiKeiko en-aut-sei=Fujii en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiNobuharu en-aut-sei=Fujii en-aut-mei=Nobuharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Okayama University kn-affil= affil-num=2 en-affil=Okayama University kn-affil= affil-num=3 en-affil=Kurashiki Central Hospital kn-affil= affil-num=4 en-affil=Kurashiki Central Hospital kn-affil= affil-num=5 en-affil=Okayama University Hospital kn-affil= affil-num=6 en-affil=Okayama University Hospital kn-affil= en-keyword=mantle cell lymphoma kn-keyword=mantle cell lymphoma en-keyword=lacrimal gland kn-keyword=lacrimal gland en-keyword=autologous peripheral blood stem cell transplantation kn-keyword=autologous peripheral blood stem cell transplantation en-keyword=breast cancer kn-keyword=breast cancer en-keyword=tracheal and bronchial infiltration kn-keyword=tracheal and bronchial infiltration END start-ver=1.4 cd-journal=joma no-vol=119 cd-vols= no-issue=43 article-no= start-page=e2122641119 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221017 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Structures and mechanisms of actin ATP hydrolysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The major cytoskeleton protein actin undergoes cyclic transitions between the monomeric G-form and the filamentous F-form, which drive organelle transport and cell motility. This mechanical work is driven by the ATPase activity at the catalytic site in the F-form. For deeper understanding of the actin cellular functions, the reaction mechanism must be elucidated. Here, we show that a single actin molecule is trapped in the F-form by fragmin domain-1 binding and present their crystal structures in the ATP analog-, ADP-Pi-, and ADP-bound forms, at 1.15-Å resolutions. The G-to-F conformational transition shifts the side chains of Gln137 and His161, which relocate four water molecules including W1 (attacking water) and W2 (helping water) to facilitate the hydrolysis. By applying quantum mechanics/molecular mechanics calculations to the structures, we have revealed a consistent and comprehensive reaction path of ATP hydrolysis by the F-form actin. The reaction path consists of four steps: 1) W1 and W2 rotations; 2) PG–O3B bond cleavage; 3) four concomitant events: W1–PO3− formation, OH− and proton cleavage, nucleophilic attack by the OH− against PG, and the abstracted proton transfer; and 4) proton relocation that stabilizes the ADP-Pi–bound F-form actin. The mechanism explains the slow rate of ATP hydrolysis by actin and the irreversibility of the hydrolysis reaction. While the catalytic strategy of actin ATP hydrolysis is essentially the same as those of motor proteins like myosin, the process after the hydrolysis is distinct and discussed in terms of Pi release, F-form destabilization, and global conformational changes. en-copyright= kn-copyright= en-aut-name=KanematsuYusuke en-aut-sei=Kanematsu en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaritaAkihiro en-aut-sei=Narita en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OdaToshiro en-aut-sei=Oda en-aut-mei=Toshiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoikeRyotaro en-aut-sei=Koike en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtaMotonori en-aut-sei=Ota en-aut-mei=Motonori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakanoYu en-aut-sei=Takano en-aut-mei=Yu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoritsuguKei en-aut-sei=Moritsugu en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=FujiwaraIkuko en-aut-sei=Fujiwara en-aut-mei=Ikuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TanakaKotaro en-aut-sei=Tanaka en-aut-mei=Kotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KomatsuHideyuki en-aut-sei=Komatsu en-aut-mei=Hideyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NagaeTakayuki en-aut-sei=Nagae en-aut-mei=Takayuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=WatanabeNobuhisa en-aut-sei=Watanabe en-aut-mei=Nobuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=IwasaMitsusada en-aut-sei=Iwasa en-aut-mei=Mitsusada kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MaédaYuichiro en-aut-sei=Maéda en-aut-mei=Yuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=TakedaShuichi en-aut-sei=Takeda en-aut-mei=Shuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Graduate School of Information Sciences, Hiroshima City University kn-affil= affil-num=2 en-affil=Structural Biology Research Center, Graduate School of Science, Nagoya University kn-affil= affil-num=3 en-affil=Faculty of Health and Welfare, Tokai Gakuin University kn-affil= affil-num=4 en-affil=Graduate School of Informatics, Nagoya University kn-affil= affil-num=5 en-affil=Graduate School of Informatics, Nagoya University kn-affil= affil-num=6 en-affil=Graduate School of Information Sciences, Hiroshima City University kn-affil= affil-num=7 en-affil=Graduate School of Medical Life Science, Yokohama City University kn-affil= affil-num=8 en-affil=Graduate School of Science, Osaka City University kn-affil= affil-num=9 en-affil=Structural Biology Research Center, Graduate School of Science, Nagoya University kn-affil= affil-num=10 en-affil=Department of Bioscience and Bioinformatics, Graduate School of Computer Science and Systems Engineering, Kyushu Institute of Technology kn-affil= affil-num=11 en-affil=Synchrotron Radiation Research Center, Nagoya University kn-affil= affil-num=12 en-affil=Synchrotron Radiation Research Center, Nagoya University kn-affil= affil-num=13 en-affil=Graduate School of Informatics, Nagoya University kn-affil= affil-num=14 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=15 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=actin kn-keyword=actin en-keyword=ATP hydrolysis kn-keyword=ATP hydrolysis en-keyword=protein crystallography kn-keyword=protein crystallography en-keyword=QM kn-keyword=QM en-keyword=MM simulation kn-keyword=MM simulation END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=5 article-no= start-page=101485 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230611 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of the comprehensive geriatric assessment in the administration of chemotherapy to older adults with cancer: Recommendations by the Japanese Geriatric Oncology Guideline Committee en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: The number of older patients with cancer is expected to continue to increase owing to the aging population. Recently, the usefulness of geriatric assessment (GA) conducted by multiple staff members from different medical backgrounds has been reported; however, a consensus on the effectiveness of GA has not yet been achieved.
Materials and Methods: We, as the Japanese Geriatric Oncology Guideline Committee for elderly patients with cancer, conducted a literature search of randomized controlled trials published before August 2021 that used GA or comprehensive GA (CGA) as an intervention for patients with cancer undergoing chemotherapy. As the key outcomes for answering the clinical question, we focused on survival benefit, adverse events, and quality of life (QOL). After a systematic review of these studies, the expert panel member developed recommendations according to the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system.
Results: For older patients with cancer, GA or CGA is suggested during or before chemotherapy (weakly recommended). Chemotherapy-induced adverse events were significantly reduced by GA/CGA interventions without any adverse effects on survival. Health-related QOL tended to improve with the GA/CGA interventions.
Discussion: Although, in our opinion, GA/CGA does require time and resources, it poses no harm patients. Therefore, we suggest expanding the human resources and educating skills of medical providers for clinical implementation of GA/CGA. en-copyright= kn-copyright= en-aut-name=NinomiyaKiichiro en-aut-sei=Ninomiya en-aut-mei=Kiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=InoueDaisuke en-aut-sei=Inoue en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SugimotoKen en-aut-sei=Sugimoto en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MurofushiKeiko en-aut-sei=Murofushi en-aut-mei=Keiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkuyamaToru en-aut-sei=Okuyama en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WatanukiShigeaki en-aut-sei=Watanuki en-aut-mei=Shigeaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ImamuraChiyo K. en-aut-sei=Imamura en-aut-mei=Chiyo K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SakaiDaisuke en-aut-sei=Sakai en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SakuraiNaomi en-aut-sei=Sakurai en-aut-mei=Naomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=WatanabeKiyotaka en-aut-sei=Watanabe en-aut-mei=Kiyotaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=TamuraKazuo en-aut-sei=Tamura en-aut-mei=Kazuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=SaekiToshiaki en-aut-sei=Saeki en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=IshiguroHiroshi en-aut-sei=Ishiguro en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= affil-num=1 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, University of Fukui kn-affil= affil-num=3 en-affil=Department of General Geriatric Medicine, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Gastroenterological Surgery, Nagoya University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Division of Radiation Oncology, Department of Radiology, Tokyo Metropolitan Cancer and Infectious Diseases Center Komagome Hospital kn-affil= affil-num=6 en-affil=Department of Psychiatry / Palliative Care Center, Nagoya City University West Medical Center kn-affil= affil-num=7 en-affil=National Center for Global Health and Medicine, National College of Nursing kn-affil= affil-num=8 en-affil=Advanced Cancer Translational Research Institute, Showa University kn-affil= affil-num=9 en-affil=Department of Frontier Science for Cancer and Chemotherapy, Osaka University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Cancer Solutions Co.,Ltd kn-affil= affil-num=11 en-affil=Division of Medical Oncology, Department of Medicine, School of Medicine, Teikyo University kn-affil= affil-num=12 en-affil=NPO Clinical Hematology/Oncology Treatment Study Group kn-affil= affil-num=13 en-affil=Breast Oncology Service, Saitama Medical University International Medical Center kn-affil= affil-num=14 en-affil=Breast Oncology Service, Saitama Medical University International Medical Center kn-affil= en-keyword=Comprehensive geriatric assessment kn-keyword=Comprehensive geriatric assessment en-keyword=Guideline kn-keyword=Guideline en-keyword=Systematic review kn-keyword=Systematic review END start-ver=1.4 cd-journal=joma no-vol=13 cd-vols= no-issue=1 article-no= start-page=8912 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230601 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of genetic loci associated with renal dysfunction after lung transplantation using an ethnic-specific single-nucleotide polymorphism array en-subtitle= kn-subtitle= en-abstract= kn-abstract=Renal dysfunction is a long-term complication associated with an increased mortality after lung transplantation (LT). We investigated the association of single-nucleotide polymorphisms (SNPs) with the development of renal dysfunction after LT using a Japanese-specific SNP array. First, eligible samples of 34 LT recipients were genotyped using the SNP array and divided into two groups, according to the presence of homozygous and heterozygous combinations of mutant alleles of the 162 renal-related SNPs. To identify candidate SNPs, the renal function tests were compared between the two groups for each SNP. Next, we investigated the association between the candidate SNPs and the time course of changes of the estimated glomerular filtration rate (eGFR) in the 99 recipients until 10 years after the LT. Delta eGFR was defined as the difference between the postoperative and preoperative eGFR values. Eight SNPs were identified as the candidate SNPs in the 34 recipients. Validation analysis of these 8 candidate SNPs in all the 99 recipients showed that three SNPs, namely, rs10277115, rs4690095, and rs792064, were associated with significant changes of the Delta eGFR. Pre-transplant identification of high-risk patients for the development of renal dysfunction after LT based on the presence of these SNPs might contribute to providing personalized medicine.

kn-abstract=Dendritic cells (DCs) present foreign antigens to T cells via the major histocompatibility complex (MHC), thereby inducing acquired immune responses. ATP accumulates at sites of inflammation or in tumor tissues, which triggers local inflammatory responses. However, it remains to be clarified how ATP modulates the functions of DCs. In this study, we investigated the effects of extracellular ATP on mouse bone marrow- derived dendritic cells (BMDCs) as well as the potential for subsequent T cell activation. We found that high concentrations of ATP (1 mM) upregulated the cell surface expression levels of MHC-I, MHC-II, and co-stimulatory molecules CD80 and CD86 but not those of co-inhibitory molecules PD-L1 and PD-L2 in BMDCs. Increased surface expression of MHC-I, MHC-II, CD80, and CD86 was inhibited by a pan-P2 receptor antagonist. In addition, the upregulation of MHC-I and MHC-II expression was inhibited by an adenosine P1 receptor antagonist and by inhibitors of CD39 and CD73, which metabolize ATP to adenosine. These results suggest that adenosine is required for the ATP-induced upregulation of MHC-I and MHC-II. In the mixed leukocyte reaction assay, ATP-stimulated BMDCs activated CD4 and CD8T cells and induced interferon-gamma (IFN-gamma) production by these T cells. Collectively, these results suggest that high concentrations of extracellular ATP upregulate the expression of antigenpresenting and co-stimulatory molecules but not that of coinhibitory molecules in BMDCs. Cooperative stimulation of ATP and its metabolite adenosine was required for the upregulation of MHC-I and MHC-II. These ATP-stimulated BMDCs induced the activation of IFN-gamma-producing T cells upon antigen presentation. en-copyright= kn-copyright= en-aut-name=FurutaKazuyuki en-aut-sei=Furuta en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OnishiHiroka en-aut-sei=Onishi en-aut-mei=Hiroka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IkadaYuki en-aut-sei=Ikada en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasakiKento en-aut-sei=Masaki en-aut-mei=Kento kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TanakaSatoshi en-aut-sei=Tanaka en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KaitoChikara en-aut-sei=Kaito en-aut-mei=Chikara kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=5 en-affil=Department of Pharmacology, Division of Pathological Sciences, Kyoto Pharmaceutical University kn-affil= affil-num=6 en-affil=Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=323 end-page=330 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Utility of Comprehensive Genomic Profiling for Precise Diagnosis of Pediatric-Type Diffuse High-Grade Glioma en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the current World Health Organization classification of central nervous system tumors, comprehensive genetic and epigenetic analyses are considered essential for precise diagnosis. A 14-year-old male patient who presented with a cerebellar tumor was initially diagnosed with glioblastoma and treated with radiation and concomitant temozolomide chemotherapy after resection. During maintenance temozolomide therapy, a new contrast-enhanced lesion developed in the bottom of the cavity formed by the resection. A second surgery was performed, but the histological findings in specimens from the second surgery were different from those of the first surgery. Although genome-wide DNA methylation profiling was conducted using frozen tissue for a precise diagnosis, the proportion of tumor cells was insufficient and only normal cerebellum was observed. We then performed comprehensive genetic analysis using formalin-fixed paraffin-embedded sections, which revealed MYCN amplification without alteration of IDH1, IDH2, or Histone H3. Finally, the patient was diagnosed with pediatric-type diffuse high-grade glioma, H3-wildtype and IDH-wildtype. In conclusion, comprehensive genetic and epigenetic analysis should be considered in pediatric brain tumor cases. en-copyright= kn-copyright= en-aut-name=MakinoKeigo en-aut-sei=Makino en-aut-mei=Keigo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiKentaro en-aut-sei=Fujii en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshidaJoji en-aut-sei=Ishida en-aut-mei=Joji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HiranoShuichiro en-aut-sei=Hirano en-aut-mei=Shuichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SurugaYasuki en-aut-sei=Suruga en-aut-mei=Yasuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=WashioKana en-aut-sei=Washio en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NishidaKenji en-aut-sei=Nishida en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanaiHiroyuki en-aut-sei=Yanai en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=TomidaShuta en-aut-sei=Tomida en-aut-mei=Shuta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=EnnishiDaisuke en-aut-sei=Ennishi en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=DateIsao en-aut-sei=Date en-aut-mei=Isao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Departments of Pediatrics, Okayama University Hospital kn-affil= affil-num=8 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Departments of Pathology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=11 en-affil=Center for Comprehensive Genomic Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Neurological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=comprehensive genomic profiling kn-keyword=comprehensive genomic profiling en-keyword=pediatric brain tumor kn-keyword=pediatric brain tumor en-keyword=genome-wide DNA methylation kn-keyword=genome-wide DNA methylation en-keyword=MYCN kn-keyword=MYCN END start-ver=1.4 cd-journal=joma no-vol=17 cd-vols= no-issue=1 article-no= start-page=23 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230612 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Quality of life and physical/psychosocial factors in children and adolescents with orthostatic intolerance en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background　Orthostatic intolerance (OI), which is common in children and adolescents, negatively impacts their quality of life (QOL) due to physical symptoms that limit work, school, and daily activities. The purpose of this study is to explore the association of physical and psychosocial factors with QOL scores in children and adolescents with OI.
Methods　A cross sectional observational study was conducted. The study participants included 95 Japanese pediatric patients of age 9-15 years who were diagnosed with OI from April 2010 to March 2020. The QOL scores and the QOL T-scores of children with OI assessed using the KINDL-R questionnaire at the initial visit were compared with conventional normative data. The associations of physical and psychosocial factors with the QOL T-scores were examined using multiple linear regression.
Results　Pediatric patients with OI had significantly lower QOL scores than healthy children in both elementary (50.7 +/- 13.5 vs. 67.9 +/- 13.4, p < 0.001) and junior high schools (51.8 +/- 14.6 vs. 61.3 +/- 12.6, p < 0.001). This finding was observed in the physical, mental, self-esteem, friends, and school domains. Total QOL scores were significantly associated with school nonattendance (beta = - 3.2, 95% confidence interval [CI] = - 5.8 to - 0.5, p = 0.022) and poor relationship with school (beta = - 5.0, 95% CI = - 9.8 to - 0.4, p = 0.035).
Conclusions　These results suggest that the assessment of QOL, including both physical and psychosocial aspects, especially school factors, needs to be implemented earlier in children and adolescents with OI. en-copyright= kn-copyright= en-aut-name=ShigeyasuYoshie en-aut-sei=Shigeyasu en-aut-mei=Yoshie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkadaAyumi en-aut-sei=Okada en-aut-mei=Ayumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujiiChikako en-aut-sei=Fujii en-aut-mei=Chikako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TanakaChie en-aut-sei=Tanaka en-aut-mei=Chie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SugiharaAkiko en-aut-sei=Sugihara en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoriuchiMakiko en-aut-sei=Horiuchi en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YorifujiTakashi en-aut-sei=Yorifuji en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TsukaharaHirokazu en-aut-sei=Tsukahara en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Clinical Psychology section, Department of Medical Support, Okayama University Hospital kn-affil= affil-num=6 en-affil=Clinical Psychology section, Department of Medical Support, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Epidemiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Pediatrics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Quality of life kn-keyword=Quality of life en-keyword=Orthostatic intolerance kn-keyword=Orthostatic intolerance en-keyword=Psychosomatic factors kn-keyword=Psychosomatic factors en-keyword=School nonattendance kn-keyword=School nonattendance en-keyword=Postural orthostatic tachycardia syndrome kn-keyword=Postural orthostatic tachycardia syndrome en-keyword=School-aged children kn-keyword=School-aged children en-keyword=Adolescence kn-keyword=Adolescence END start-ver=1.4 cd-journal=joma no-vol=2023 cd-vols= no-issue=6 article-no= start-page=063H01 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230505 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Angular correlation of the two gamma rays produced in the thermal neutron capture on gadolinium-155 and gadolinium-157 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The ANNRI-Gd collaboration studied in detail the single gamma-ray spectrum produced from the thermal neutron capture on Gd-155 and Gd-157 in our previous publications. Gadolinium targets were exposed to a neutron beam provided by the Japan Spallation Neutron Source (JSNS) in J-PARC, Japan. In the present analysis, one new additional coaxial germanium crystal was used in combination with the 14 germanium crystals in the cluster detectors to study the angular correlation of the two gamma rays emitted in the same neutron capture. We present for the first time angular correlation functions for two gamma rays produced during the electromagnetic cascade transitions in the (n, gamma) reactions on Gd-155 and Gd-157. As expected, we observe mild angular correlations for the strong, but rare transitions from the resonance state to the two energy levels of known spin-parities. Contrariwise, we observe negligibly small angular correlations for arbitrary pairs of two gamma rays produced in the majority of cascade transitions from the resonance state to the dense continuum states. en-copyright= kn-copyright= en-aut-name=GouxPierre en-aut-sei=Goux en-aut-mei=Pierre kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=GlessgenFranz en-aut-sei=Glessgen en-aut-mei=Franz kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GazzolaEnrico en-aut-sei=Gazzola en-aut-mei=Enrico kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ReenMandeep Singh en-aut-sei=Reen en-aut-mei=Mandeep Singh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=FocillonWilliam en-aut-sei=Focillon en-aut-mei=William kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=GoninMichel en-aut-sei=Gonin en-aut-mei=Michel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TanakaTomoyuki en-aut-sei=Tanaka en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HagiwaraKaito en-aut-sei=Hagiwara en-aut-mei=Kaito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=AliAjmi en-aut-sei=Ali en-aut-mei=Ajmi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SudoTakashi en-aut-sei=Sudo en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KoshioYusuke en-aut-sei=Koshio en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=SakudaMakoto en-aut-sei=Sakuda en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=CollazuolGianmaria en-aut-sei=Collazuol en-aut-mei=Gianmaria kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=KimuraAtsushi en-aut-sei=Kimura en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NakamuraShoji en-aut-sei=Nakamura en-aut-mei=Shoji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=IwamotoNobuyuki en-aut-sei=Iwamoto en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= en-aut-name=HaradaHideo en-aut-sei=Harada en-aut-mei=Hideo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=17 ORCID= en-aut-name=WurmMichael en-aut-sei=Wurm en-aut-mei=Michael kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=18 ORCID= affil-num=1 en-affil=Department of Physics, Okayama University kn-affil= affil-num=2 en-affil=Department of Physics, Okayama University kn-affil= affil-num=3 en-affil=Department of Physics, Okayama University kn-affil= affil-num=4 en-affil=Department of Physics, Okayama University kn-affil= affil-num=5 en-affil=Département de Physique, École Polytechnique, IN2P3/CNRS kn-affil= affil-num=6 en-affil=Département de Physique, École Polytechnique, IN2P3/CNRS kn-affil= affil-num=7 en-affil=Department of Physics, Okayama University kn-affil= affil-num=8 en-affil=Department of Physics, Okayama University kn-affil= affil-num=9 en-affil=Department of Physics, Okayama University kn-affil= affil-num=10 en-affil=Department of Physics, Okayama University kn-affil= affil-num=11 en-affil=Department of Physics, Okayama University kn-affil= affil-num=12 en-affil=Department of Physics, Okayama University kn-affil= affil-num=13 en-affil=INFN Sezione di Padova and Università di Padova, Dipartimento di Fisica kn-affil= affil-num=14 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=15 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=16 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=17 en-affil=Japan Atomic Energy Agency kn-affil= affil-num=18 en-affil=Institut für Physik, Johannes Gutenberg-Universität Mainz kn-affil= END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=291 end-page=299 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Comparison of the Efficacy of Plastic Stent Placement Above and Across the Sphincter of Oddi for Benign Biliary Hilar Stricture en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated the efficacy and safety of endoscopic plastic stent (PS) placement for hilar benign biliary strictures (BBSs) and compared cases with PS placement above (inside stent, IS) and across (usual stent, US) the sphincter of Oddi. Patients who underwent initial endoscopic PS placement for hilar BBSs between August 2012 and December 2021 were retrospectively analyzed. Hilar BBSs in 88 patients were investigated. Clinical success was achieved in 81 of these cases (92.0%), including 38 patients in the IS group and 43 patients in the US group. Unexpected stent exchange (uSE) before the first scheduled PS exchange occurred in 18 cases (22.2%). The median time from first stent placement to uSE was 35 days. There was no significant difference in the rate and median time to uSE between the two groups. The rates of adverse events such as pancreatitis or cholangitis in the two groups did not significantly differ. However, the rate of difficult stent removal in the IS group (15.8%) was significantly higher than that in the US group (0%) (p=0.0019). US placement is preferable to IS placement for scheduled stent exchange, as it offers the same effectiveness and risk of adverse events with easier stent removal. en-copyright= kn-copyright= en-aut-name=HimeiHitomi en-aut-sei=Himei en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SaragaiYosuke en-aut-sei=Saragai en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UchidaDaisuke en-aut-sei=Uchida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=HoriguchiShigeru en-aut-sei=Horiguchi en-aut-mei=Shigeru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TsutsumiKoichiro en-aut-sei=Tsutsumi en-aut-mei=Koichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=benign biliary stricture kn-keyword=benign biliary stricture en-keyword=inside stent kn-keyword=inside stent en-keyword=plastic stent kn-keyword=plastic stent END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=273 end-page=280 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202306 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usefulness of Simple Diffusion Kurtosis Imaging for Head and Neck Tumors: An Early Clinical Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Diffusion kurtosis (DK) imaging (DKI), a type of restricted diffusion-weighted imaging, has been reported to be useful for tumor diagnoses in clinical studies. We developed a software program to simultaneously create DK images with apparent diffusion coefficient (ADC) maps and conducted an initial clinical study. Multi-shot echo-planar diffusion-weighted images were obtained at b-values of 0, 400, and 800 sec/mm2 for simple DKI, and DK images were created simultaneously with the ADC map. The usefulness of the DK image and ADC map was evaluated using a pixel analysis of all pixels and a median analysis of the pixels of each case. Tumor and normal tissues differed significantly in both pixel and median analyses. In the pixel analysis, the area under the curve was 0.64 for the mean kurtosis (MK) value and 0.77 for the ADC value. In the median analysis, the MK value was 0.74, and the ADC value was 0.75. The MK and ADC values correlated moderately in the pixel analysis and strongly in the median analysis. Our simple DKI system created DK images simultaneously with ADC maps, and the obtained MK and ADC values were useful for differentiating head and neck tumors from normal tissue. en-copyright=

patients with cancer cachexia after anamorelin administration have not been fully investigated. This study aimed to determine how anamorelin affects the endocrine system in patients with gastrointestinal cancer and cachexia. We prospectively enrolled 13 patients and comprehensively investigated their body weight and levels of serum albumin, hemoglobin A1c (HbA1c), and hormones before (week 0) and 3 and 12 weeks after anamorelin administration. The variables were evaluated at week 3 in 9 patients and at week 12 in 5 patients. At week 3, anamorelin administration resulted in body weight gain and increased the levels of growth hormone and HbA1c, as well as insulin-like growth factor-1 standard deviation scores (IGF-1 SD scores). At the same time, negative correlations were observed between ΔIGF-1 SD score and Δthyroidstimulating hormone (TSH) and between ΔIGF-1 SD score and Δfree testosterone. ΔBody weight and ΔIGF-1 SD score correlated positively at week 12. These results suggest that TSH and free testosterone levels can be affected 3 weeks after anamorelin administration; however, those variables tend to return to a state of equilibrium, and anabolic effects of anamorelin appear in long-term (≥ 12 weeks) users. en-copyright= kn-copyright= en-aut-name=KuraokaSakiko en-aut-sei=Kuraoka en-aut-mei=Sakiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro en-aut-mei=Masaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SatomiTakuya en-aut-sei=Satomi en-aut-mei=Takuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HamadaKenta en-aut-sei=Hamada en-aut-mei=Kenta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtsukaFumio en-aut-sei=Otsuka en-aut-mei=Fumio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=OkadaHiroyuki en-aut-sei=Okada en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=anamorelin kn-keyword=anamorelin en-keyword=body weight kn-keyword=body weight en-keyword=cancer cachexia kn-keyword=cancer cachexia en-keyword=endocrine system kn-keyword=endocrine system END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=1 article-no= start-page=1 end-page=27 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230331 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Geology of the Paleogene to Neogene successions and gentle upwarping of the Kibi Plateau Surface, surrounding area of Kibichuou Town, Okayama Prefecture, Southwest Japan kn-title=岡山県吉備中央町賀陽周辺の古第三系～新第三系の地質と吉備高原面のゆるやかな曲隆 en-subtitle= kn-subtitle= en-abstract= kn-abstract=The Paleogene to Neogene successions which are composed of the Paleogene Kayo Formation, the late Oligocene to earliest Miocene Yagane Formation and the middle Miocene Ukan Formation are sporadically distributed in the Kibi Plateau region, surrounding area of Kibichuou Town, Okayama Prefecture, Southwest Japan. The gravel of the Kayo Formation occupied paleo-valley of Pre-Paleogene basement. The Yagane and Ukan formations unconformably overlay Pre-Paleogene rocks and occupy the gentle valley on the Kibi Surface as valley fill deposits.
The fluvial of the Kayo Formation is mainly composed of conglomerate with minor amount of sandstone and mudstone. The fluvial Yagane Formation is mainly composed of conglomerate and associated with sandstone, mudstone and coal beds. The marine Ukan Formation is subdivided into 3 members, the Yamagata Muddy sandstone Member (YMM), the Shimoyokomi Sandstone Member (SSM) and the Tsuneyama Mudstone Member (TMM) in ascending order. The YMM is characterized by the bio-disturbed very poorly sorted muddy sandstone with frequent burrows, which indicate tidal flat deposits. The SSM is mainly composed of parallel bedded well-sorted sandstone with occasional burrows, which suggest near shore deposits. The TMM is composed of homogeneous clay rich mudstone, which implies off shore deposits.
The boundary between the SSM and TMM (the contact of the sandstone and mudstone) is distinctive and correlative throughout the study area. The boundary is considered to be formed under similar water depth. The variations of the boundary height indicate a later ground movement. From the north to the south in about 25km distance, the height of the boundary changes 260m (in Ukan), 300m (in Takeshou), 360m (in Kibikogentoshi) and 260m (in Nichiouji). It indicates that a very gentle upwarping of the Kibi Plateau Surface was formed after the deposition of the Miocene. en-copyright= kn-copyright= en-aut-name=TANAKAHajime en-aut-sei=TANAKA en-aut-mei=Hajime kn-aut-name=田中元 kn-aut-sei=田中 kn-aut-mei=元 aut-affil-num=1 ORCID= en-aut-name=SUZUKIShigeyuki en-aut-sei=SUZUKI en-aut-mei=Shigeyuki kn-aut-name=鈴木茂之 kn-aut-sei=鈴木 kn-aut-mei=茂之 aut-affil-num=2 ORCID= affil-num=1 en-affil=Seibu Engineering Consultants Co., Ltd. kn-affil=西部技術コンサルタント株式会社 affil-num=2 en-affil=Department of Earth Sciences, Okayama University kn-affil=岡山大学理学部地球科学科 en-keyword=Kibi Plateau Surface kn-keyword=Kibi Plateau Surface en-keyword=Upwarping kn-keyword=Upwarping en-keyword=Miocene kn-keyword=Miocene en-keyword=Ukan Formation kn-keyword=Ukan Formation END
