This phenomenon is particularly notable under loads applied in the "edge-wise direction", where each layer bears stress collectively. These combined effects are referred to as the "adhesive effect". Strength under partial compressive loads is critical in timber engineering, as partial compressive stress generates complex stress distributions influenced by boundary conditions. The adhesive effect may also be impacted by these conditions. The aim of this study was to quantitatively and directly evaluate the adhesive effect under partial and full compressive loads using various parameters. The strength of laminated veneer lumber (LVL) with adhesive was compared to that of simply layered veneers without adhesive to assess the adhesive effect. Three mechanisms contributing to the adhesive effect were proposed: Mechanism I, caused by the deformation of the adhesive layer independently from the veneers; Mechanism II, resulting from the adhesive impregnating the veneers; and Mechanism III, arising from the reinforcement provided by adjacent veneers. The results suggested the following: (i) Mechanism I had minimal impact, as the fiber direction and the presence of additional length showed strong and slight effects on the adhesive effect, respectively; (ii) Mechanism II contributed to preventing crack propagation and altering the relationships among mechanical properties, with its effectiveness increasing as the adhesive weight increased; and (iii) Mechanism III functioned as a crossband effect, reinforcing weaknesses caused by the slope of the grain and the angle of the annual rings. en-copyright= kn-copyright= en-aut-name=SudoRyutaro en-aut-sei=Sudo en-aut-mei=Ryutaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoKohta en-aut-sei=Miyamoto en-aut-mei=Kohta kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IdoHirofumi en-aut-sei=Ido en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Okayama University, Graduate School of Environmental, Life, Natural Science and Technology kn-affil= affil-num=2 en-affil=Forestry and Forest Products Research Institute kn-affil= affil-num=3 en-affil=Forestry and Forest Products Research Institute kn-affil= en-keyword=Laminated veneer lumber (LVL) kn-keyword=Laminated veneer lumber (LVL) en-keyword=Partial compressive load kn-keyword=Partial compressive load en-keyword=Bearing strength kn-keyword=Bearing strength en-keyword=Embedment strength kn-keyword=Embedment strength en-keyword=Partial compression perpendicular to grain (PCPG) kn-keyword=Partial compression perpendicular to grain (PCPG) en-keyword=Adhesive layer kn-keyword=Adhesive layer END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=7 article-no= start-page=2287 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250327 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Midazolam and Diazepam for Sedation in Patients Undergoing Double-Balloon Endoscopic Retrograde Cholangiopancreatography: A Propensity Score-Matched Analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objective: The sedation method used in double-balloon endoscopic retrograde cholangiopancreatography (DB-ERCP) varies across countries and between healthcare facilities. No previous studies have compared the effects of different benzodiazepines on sedation during endoscopic procedures. This study aimed to compare the effects of midazolam and diazepam sedation on DB-ERCP outcomes. Methods: This retrospective cohort study analyzed consecutive patients who underwent DB-ERCP between January 2017 and February 2024. A total of 203 patients who were sedated with diazepam (n = 94) or midazolam (n = 109) were analyzed. Propensity score matching was applied to adjust for baseline group differences. The primary outcome was the incidence of sedation-related adverse events (AEs). Secondary outcomes included inadequate sedation requiring additional sedatives and risk factors for sedation-related AEs. Results: Sedation-related AEs were more frequent with diazepam (28% [21/75]) than with midazolam (14% [11/75]; p = 0.046). Hypoxia occurred more frequently with diazepam (19% [14/75]) than with midazolam (5% [4/75]; p = 0.012). However, no significant differences were observed between the two groups for hypotension (p = 0.41) and bradycardia (p = 1.0). Poor sedation requiring other sedatives occurred significantly more often with diazepam (8% [6/75]) compared with midazolam sedation (0% [0/75], p = 0.012). Multivariate analysis identified diazepam sedation (odds ratio, 2.3; 95% confidence interval, 1.0-5.3; p = 0.048) as the sole risk factor for sedation-related AEs. Conclusions: Midazolam is safer and more effective than diazepam sedation in patients undergoing DB-ERCP. en-copyright= kn-copyright= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki 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=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=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=OtsukaMotoyuki en-aut-sei=Otsuka en-aut-mei=Motoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=adverse events kn-keyword=adverse events en-keyword=balloon-assisted ERCP kn-keyword=balloon-assisted ERCP en-keyword=benzodiazepine kn-keyword=benzodiazepine en-keyword=sedation kn-keyword=sedation 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=

length is a crucial factor for delayed bleeding after endoscopic papillectomy: a retrospective multicenter cohort study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Bleeding is a serious and frequent adverse event that occurs during and after endoscopic papillectomy (EP). Previous studies have highlighted the effectiveness of preventive clipping closure of the resection site in preventing post-EP bleeding. However, the optimal length of closure remained unclear.
Objectives: We aimed to clarify the optimal clipping length at the post-EP resection site to prevent delayed bleeding.
Design: This study was a multicenter retrospective cohort study.
] Methods: We retrospectively analyzed patients who were consecutively admitted to nine high-volume centers for EP between November 2003 and October 2023. The primary outcome was the frequency of delayed bleeding based on the closure length. The optimal closure length rate of the resected site to prevent delayed bleeding was determined using a receiver operating characteristic curve. Secondary outcomes were the incidence, treatment outcomes, and risk factors for post-EP delayed bleeding.
Results: A total of 130 patients who underwent EP were analyzed. Delayed bleeding was observed in 22 (17%) patients, occurring more frequently in cases without clipping closure than in those with clipping closure (28% (13/47) vs 11% (9/83); p = 0.014). Among 83 patients who underwent clipping closure, delayed bleeding occurred more frequently with a closure length rate <65% than in those with a closure rate >= 65% (25% (5/20) vs 6% (4/63); p = 0.019). Multivariate analysis showed that a closure rate <65% was the risk factor for delayed bleeding (odds ratio, 6.3; 95% confidence interval, 1.2-33; p = 0.030) in cases with clipping.
Conclusion: Clipping closure was effective in preventing delayed bleeding, and closure length rate >= 65% of the resected site significantly reduced post-EP delayed bleeding. en-copyright=

Sales equally involve legal issues such as sales contracts. this paper suggests an elementary social studies unit using a supermarket as a teaching material, based on Law-Related Education research accumulated in social studies education research to date. kn-abstract= 本論文は、小学校社会科における市民性教育としての法教育のあり方を検討し、その授業構成原理を明らかにしたうえで、中学年の教育内容である販売の仕事に関する単元開発を行うものである。これまで小学校法教育では、発達心理学の論を基にしながら研究が進められてきたが、小学校社会科法教育としての体系的な研究は十分ではなかった。小学校第3学年の社会科では、第3学年「地域にみられる生産や販売の仕事について」の内容が設定されている。佐藤はスーパーマーケットを教材として小学校社会科で経済概念を形成する授業を開発し、その有効性を検証した。一方で、販売には売買契約のような法的問題も発生する。本論文では、これまでの社会科教育研究において蓄積されてきた法教育論や価値観形成論の成果を踏まえ、スーパーマーケットを教材とした小学校社会科単元開発を行う。 en-copyright= kn-copyright= en-aut-name=MIYAMOTOAyuha en-aut-sei=MIYAMOTO en-aut-mei=Ayuha kn-aut-name=宮本あゆは kn-aut-sei=宮本 kn-aut-mei=あゆは aut-affil-num=1 ORCID= en-aut-name=KUWABARAToshinori en-aut-sei=KUWABARA en-aut-mei=Toshinori kn-aut-name=桑原敏典 kn-aut-sei=桑原 kn-aut-mei=敏典 aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Humanities and Social Sciences, Okayama University kn-affil=岡山大学大学院社会文化科学研究科博士後期課程 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=法教育 (Law-Related Education) kn-keyword=法教育 (Law-Related Education) en-keyword=初等教育 (Elementary School Education) kn-keyword=初等教育 (Elementary School Education) en-keyword=小学校社会科 (Social Studies) kn-keyword=小学校社会科 (Social Studies) en-keyword=民法学習 (Civil Law Education) kn-keyword=民法学習 (Civil Law Education) END start-ver=1.4 cd-journal=joma no-vol=15 cd-vols= no-issue= article-no= start-page=33 end-page=44 dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250328 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Systematic Improvement of Lessons in Elementary Schools –A Case Study of Japanese Language Instruction Aimed at Realizing the “Ideal Child Image”– kn-title=小学校における組織的な授業改善のあり方 〜「目指す子ども像」実現に向けた国語科指導を事例として〜 en-subtitle= kn-subtitle= en-abstract= kn-abstract= 本研究の目的は、「目指す子ども像」実現に向けた国語科の授業づくりの具体を検討し、小学校における組織的な授業改善のあり方を提言することにある。具体的には、「目指す子ども像」実現に向けた国語科の授業づくりを通して、今の社会が小学校教育に求める特色ある授業づくりの進め方を明らかにするため、勤務校である早島町立早島小学校に所属する教師の授業づくりを対象に事例研究を展開した。検討を通じて明らかになったことは、授業づくりにおける教師の思考・実践過程と、これらを実践者が反省的に捉え直すための「目指す子ども像」による言語活動具体化の手立てである。さらに、授業づくりの組織・系統性は、他学年教師の役割によってもたらされることが確認されたことから、それらを踏まえつつ、「目指す子ども像」実現に向けた授業づくりのあり方を体系化した。そうすることで、小学校における組織的な授業改善を進めていくための可能性が見出された。 en-copyright= kn-copyright= en-aut-name=KOMOTOAkihiro en-aut-sei=KOMOTO en-aut-mei=Akihiro kn-aut-name=河本章宏 kn-aut-sei=河本 kn-aut-mei=章宏 aut-affil-num=1 ORCID= en-aut-name=MIYAMOTOKoji en-aut-sei=MIYAMOTO en-aut-mei=Koji kn-aut-name=宮本浩治 kn-aut-sei=宮本 kn-aut-mei=浩治 aut-affil-num=2 ORCID= en-aut-name=IKEDAMasafumi en-aut-sei=IKEDA en-aut-mei=Masafumi kn-aut-name=池田匡史 kn-aut-sei=池田 kn-aut-mei=匡史 aut-affil-num=3 ORCID= en-aut-name=MATUDASatoshi en-aut-sei=MATUDA en-aut-mei=Satoshi kn-aut-name=松田聡 kn-aut-sei=松田 kn-aut-mei=聡 aut-affil-num=4 ORCID= affil-num=1 en-affil=Hayashima Elementary School (Graduate School of Education (Professional Degree Corse), Okayama University) kn-affil=岡山大学大学院教育学研究科大学院生 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 affil-num=3 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 affil-num=4 en-affil=Faculty of Education, Okayama University kn-affil=岡山大学学術研究院教育学域 en-keyword=目指す子ども像 (The school's educational goals) kn-keyword=目指す子ども像 (The school's educational goals) en-keyword=価値目標 (into value-objectives) kn-keyword=価値目標 (into value-objectives) en-keyword=国語学力 (Japanese language ability) kn-keyword=国語学力 (Japanese language ability) en-keyword=カリキュラムマネジメント (Curriculum Management) kn-keyword=カリキュラムマネジメント (Curriculum Management) en-keyword=組織・系統性 (Organization and Systematic) kn-keyword=組織・系統性 (Organization and Systematic) END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=e70096 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250311 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic ultrasonography-guided removal of a stent that had migrated into the pancreas post-pancreaticojejunostomy: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 64-year-old woman had undergone subtotal stomach-preserving pancreaticoduodenectomy for locally advanced pancreatic head cancer. She had an uneventful postoperative course with no recurrence. However, approximately 18 months after surgery, she presented with recurrent abdominal pain. Although contrast-enhanced computed tomography abdominal radiographs showed internal stent migration to the residual pancreas, dilatation of the tail side of the pancreatic duct was observed. The impaired internal stent was considered to be the cause of the abdominal pain. An attempt to remove the stent via balloon-assisted endoscopy was unsuccessful as the pancreaticojejunostomy site could not be reached. Consequently, endoscopic ultrasonography-guided pancreatic duct drainage was performed, and a plastic stent was placed through the jejunal site to the stomach. Two months later, the endosonographically/endoscopic ultrasonography-guided created route was dilated, and an endoscopic introducer was inserted into the pancreatic duct. Biopsy forceps were advanced through the sheath, allowing the successful removal of the stent by direct grasping. The symptoms of the patient improved, and she was discharged without complications. en-copyright= kn-copyright= en-aut-name=KajitaniSatoshi en-aut-sei=Kajitani en-aut-mei=Satoshi 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=OkiKentaro en-aut-sei=Oki en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 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=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 andHepatology, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology andHepatology, Okayama University Hospital kn-affil= en-keyword=endoscopic introducer kn-keyword=endoscopic introducer en-keyword=endoscopic ultrasonography-guided pancreatic duct drainage kn-keyword=endoscopic ultrasonography-guided pancreatic duct drainage en-keyword=endosonographically/EUS-guided created route kn-keyword=endosonographically/EUS-guided created route en-keyword=EUS-guided interventions kn-keyword=EUS-guided interventions en-keyword=internal stent kn-keyword=internal stent END start-ver=1.4 cd-journal=joma no-vol=188 cd-vols= no-issue= article-no= start-page=1 end-page=13 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=Wie setzt sich die Didaktik mit der “Learnification of Education” auseinnander?

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=5 cd-vols= no-issue=1 article-no= start-page=e70073 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2025 dt-pub=20250129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and safety of endoscopic ultrasonography-guided radiofrequency ablation of small pancreatic neuroendocrine neoplasms: A prospective, pilot study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Objectives: Endoscopic ultrasonography (EUS)-guided radiofrequency ablation has recently been introduced as one of the management strategies for small pancreatic neuroendocrine neoplasms (PNENs). However, prospective data on its safety and efficacy remain limited.
Methods: This prospective pilot study was conducted at Okayama University Hospital from May 2023 to December 2024. Patients with grade 1 PNENs <= 15 mm, confirmed by EUS-guided fine-needle aspiration, were included. The primary endpoint was safety (adverse events [AEs] evaluated according to the 2010 guidelines of the American Society for Gastrointestinal Endoscopy. Severe AEs were defined as moderate or higher in American Society for Gastrointestinal Endoscopy grading and grade >= 3. Secondary endpoints included efficacy (complete response on contrast-enhanced computed tomography at 1 and 6 months), treatment details, device failure, diabetes mellitus exacerbation, and overall survival at 6 months.
Results: Five patients with non-functional PNENs (median age: 64 years; median tumor size: 10 mm) were treated. AEs occurred in two patients (40%, 2/5), although none was severe. Both patients developed asymptomatic pseudocysts, one experienced mild pancreatitis, and both resolved with conservative treatment. The complete response rates on contrast-enhanced computed tomography at one and 6 months were 100%. The median procedure time was 16 min without any device failure, and the median hospitalization was 5 days. None of the patients developed new-onset or worsening diabetes mellitus. The 6-month overall survival rate was 100%.
Conclusion: EUS-guided radiofrequency ablation demonstrated a high complete response rate with no severe AEs in this pilot study, suggesting a minimally invasive option for small, low-grade PNENs (jRCTs062230014). en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TakeuchiYasuto en-aut-sei=Takeuchi en-aut-mei=Yasuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=HaradaKei en-aut-sei=Harada en-aut-mei=Kei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=HattoriNao en-aut-sei=Hattori en-aut-mei=Nao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 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=12 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=13 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=HaradaRyo en-aut-sei=Harada en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=FujiiMasakuni en-aut-sei=Fujii en-aut-mei=Masakuni kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 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=17 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital 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= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterological Surgery, Transplant and Surgical Oncology, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Gastroenterology, Japanese Red Cross Okayama Hospital kn-affil= affil-num=16 en-affil=Department of Internal Medicine, Okayama Saiseikai General Hospital kn-affil= affil-num=17 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=ablation techniques kn-keyword=ablation techniques en-keyword=endosonography kn-keyword=endosonography en-keyword=neuroendocrine tumors kn-keyword=neuroendocrine tumors en-keyword=pancreatic neoplasms kn-keyword=pancreatic neoplasms en-keyword=pilot projects kn-keyword=pilot projects 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=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. Emergent percutaneous coronary intervention for the left anterior descending artery (#7) was successfully performed. However, echocardiography revealed a ventricular septal rupture (25×27 mm). 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=106 cd-vols= no-issue=5 article-no= start-page=972 end-page=984 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=202411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A randomized, open-label, clinical trial examined the effects of canagliflozin on albuminuria and eGFR decline using an individual pre-intervention eGFR slope en-subtitle= kn-subtitle= en-abstract= kn-abstract=Demonstrating drug efficacy in slowing kidney disease progression requires large clinical trials when targeting participants with an early stage of chronic kidney disease (CKD). In this randomized, parallel-group, open-labeled trial (CANPIONE study), we assessed the effect of the sodium-glucose cotransporter 2 (SGLT2) inhibitor canagliflozin using the individual’s change in estimated glomerular filtration rate (eGFR) slope before (pre-intervention slope) and during treatment (chronic slope). We randomly assigned (1:1) participants with type 2 diabetes, urinary albumin-to-creatinine ratio (UACR) of 50 to under 300 mg/g, and an eGFR of at least 45 ml/min/1.73m2 to receive canagliflozin or guideline-recommended treatment except for SGLT2 inhibitors (control). The first and second primary outcomes were the geometric mean percentage change from baseline in UACR and the change in eGFR slope, respectively. Of 98 randomized participants, 96 received at least one study treatment. The least-squares mean change from baseline in log-transformed geometric mean UACR was significantly greater in the canagliflozin group than the control group (between group-difference, −30.8% (95% confidence interval −42.6 to −16.8). The between-group difference (canagliflozin group – control group) of change in eGFR slope (chronic – pre-intervention) was 4.4 (1.6 to 7.3) ml/min/1.73 m2 per year, which was more pronounced in participants with faster eGFR decline. In summary, canagliflozin reduced albuminuria and the participant-specific natural course of eGFR decline in participants with type 2 diabetes and microalbuminuria. Thus, the CANPIONE study suggests that the within-individual change in eGFR slope may be a novel approach to determine the kidney protective potential of new therapies in early stages of CKD.

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rapid on-site cytopathology evaluation (ROSE) has been considered an effective method to increase the diagnostic ability of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA); however, ROSE is unavailable in most institutes worldwide due to the shortage of cytopathologists. To overcome this situation, we created an artificial intelligence (AI)-based system (the ROSE-AI system), which was trained with the augmented data to evaluate the slide images acquired by EUS-FNA. This study aimed to clarify the effects of such data-augmentation on establishing an effective ROSE-AI system by comparing the efficacy of various data-augmentation techniques. The ROSE-AI system was trained with increased data obtained by the various data-augmentation techniques, including geometric transformation, color space transformation, and kernel filtering. By performing five-fold cross-validation, we compared the efficacy of each data-augmentation technique on the increasing diagnostic abilities of the ROSE-AI system. We collected 4059 divided EUS-FNA slide images from 36 patients with pancreatic cancer and nine patients with non-pancreatic cancer. The diagnostic ability of the ROSE-AI system without data augmentation had a sensitivity, specificity, and accuracy of 87.5%, 79.7%, and 83.7%, respectively. While, some data-augmentation techniques decreased diagnostic ability, the ROSE-AI system trained only with the augmented data using the geometric transformation technique had the highest diagnostic accuracy (88.2%). We successfully developed a prototype ROSE-AI system with high diagnostic ability. Each data-augmentation technique may have various compatibilities with AI-mediated diagnostics, and the geometric transformation was the most effective for the ROSE-AI system. en-copyright=

Milk, Airag en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bacteriocins produced by lactic acid bacteria are known to be useful tools for food biopreservation and fermentation control. Leuconostoc mesenteroides subsp. mesenteroides 406 and 213M0 isolated from different samples of Mongolian traditional fermented milk, airag, had been reported to produce listericidal bacteriocin-like inhibitory substances with similar but slightly different properties. In this study, the antibacterial properties and the related gene sequences of both strains were compared, and then their bacteriocins were purified and identified. Strain 406 was superior to strain 213M0 in cell growth and antibacterial activity against many strains. However, the activity of 213M0 was stronger than that of 406 against a few strains. DNA sequencing revealed two and three plasmids in 406 and 213M0, respectively, and each one of them harbored an almost identical mesentericin Y105-B105 gene cluster. Removal of these plasmids resulted in a complete loss of activity, indicating that the antibacterial activity of both strains was generated by bacteriocins encoded on the plasmids. Mesentericins Y105 and B105 were purified from both cultures, and another novel bacteriocin, named mesentericin M, was identified from the 213M0 culture only. Its structural gene was coded on a 213M0 plasmid and, surprisingly, its C-terminal three amino acid residues were post-translationally cleaved. To our knowledge, this is the first report of a C-terminal truncated bacteriocin. In conclusion, the novel bacteriocin should be mainly responsible for the difference in antibacterial properties between the two strains. en-copyright= kn-copyright= en-aut-name=HasiqimugeChihiro en-aut-sei=Hasiqimuge en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanoChihiro en-aut-sei=Hano en-aut-mei=Chihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ArakawaKensuke en-aut-sei=Arakawa en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YoshidaSaki en-aut-sei=Yoshida en-aut-mei=Saki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=ZhaoJunliang en-aut-sei=Zhao en-aut-mei=Junliang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TohHidehiro en-aut-sei=Toh en-aut-mei=Hidehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MoritaHidetoshi en-aut-sei=Morita en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoTaku en-aut-sei=Miyamoto en-aut-mei=Taku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=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=Advanced Genomics Center, National Institute of Genetics kn-affil= affil-num=7 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Leuconostoc mesenteroides kn-keyword=Leuconostoc mesenteroides en-keyword=antimicrobial peptide kn-keyword=antimicrobial peptide en-keyword=bacteriocin kn-keyword=bacteriocin en-keyword=Listeria monocytogenes kn-keyword=Listeria monocytogenes en-keyword=fermented milk kn-keyword=fermented milk en-keyword=biopreservation kn-keyword=biopreservation en-keyword=fermentation control kn-keyword=fermentation control en-keyword=post-translational modification kn-keyword=post-translational modification en-keyword=C-terminal cleavage kn-keyword=C-terminal cleavage END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=17 article-no= start-page=2824 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240823 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Cyclic Oligosaccharide-Induced Modulation of Immunoglobulin A Reactivity to Gut Bacteria Contributes to Alterations in the Bacterial Community Structure en-subtitle= kn-subtitle= en-abstract= kn-abstract=Immunoglobulin A (IgA) is a major gut antibody that coats commensal gut bacteria and contributes to shaping a stable gut bacterial composition. Although previous studies have shown that cyclic oligosaccharides, including cyclic nigerosyl-1,6-nigerose (CNN) and cyclodextrins (CDs, including alpha CD, beta CD, and gamma CD), alter the gut bacterial composition, it remains unclear whether cyclic oligosaccharides modify the IgA coating of gut bacteria, which relates to cyclic oligosaccharide-induced alteration of the gut bacterial composition. To address this issue, mice were maintained for 12 weeks on diets containing CNN, alpha CD, beta CD, or gamma CD; the animals' feces were evaluated for their bacterial composition and the IgA coating index (ICI), a measure of the degree of IgA coating of bacteria. We observed that the intake of each cyclic oligosaccharide altered the gut bacterial composition, with changes in the ICI found at both the phylum and genus levels. The ICI for Bacillota, Lachnospiraceae NK4A136 group, UC Lachnospiraceae, and Tuzzerella were significantly and positively correlated with the relative abundance (RA) in total bacteria for these bacteria; in contrast, significant correlations were not seen for other phyla and genera. Our observations suggest that cyclic oligosaccharide-induced modulation of the IgA coating of gut bacteria may partly relate to changes in the community structure of the gut bacteria. en-copyright= kn-copyright= en-aut-name=MiyamotoTaisei en-aut-sei=Miyamoto en-aut-mei=Taisei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TsurutaTakeshi en-aut-sei=Tsuruta en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TeraokaMao en-aut-sei=Teraoka en-aut-mei=Mao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WangTianyang en-aut-sei=Wang en-aut-mei=Tianyang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishinoNaoki en-aut-sei=Nishino en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=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= en-keyword=cyclic oligosaccharides kn-keyword=cyclic oligosaccharides en-keyword=gut bacteria kn-keyword=gut bacteria en-keyword=immunoglobulin A kn-keyword=immunoglobulin A END start-ver=1.4 cd-journal=joma no-vol=112 cd-vols= no-issue=2 article-no= start-page=419 end-page=424 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240909 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Electrochemically assisted sol-gel deposition of bioactive gels for biomedical applications en-subtitle= kn-subtitle= en-abstract= kn-abstract=So far, the sol-gel process has been available to prepare precursor gels of bioactive glasses with various compositions. In this report, we described a novel coating method of bioactive gels on a titanium substrate where the sol-gel transition is controlled by applying external electric fields. The application of a constant current of 10 mA/cm2 in an acidic sol containing pre-hydrolyzed tetraethoxysilane, calcium nitrate, and ammonium dihydrogen phosphate led to the deposition of gels on the titanium cathodes due to the generation of OH– by water electrolysis as a catalyst of the sol-gel transition. The obtained gels, which were characterized to be amorphous and consisted of Si, Ca, and P, covered the titanium substrates as a coating. The bioactivity of the gels deposited was confirmed by soaking in a simulated body fluid (SBF) up to 7 days, suggesting that the electrochemically assisted sol-gel process is promising for providing bioactive coatings on metallic implants. en-copyright= kn-copyright= en-aut-name=YoshiokaTomohiko en-aut-sei=Yoshioka en-aut-mei=Tomohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoNaoki en-aut-sei=Miyamoto en-aut-mei=Naoki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HayakawaSatoshi en-aut-sei=Hayakawa en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Biomaterials Laboratory, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Biomaterials Laboratory, Faculty of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=Sol-gel-derived gels kn-keyword=Sol-gel-derived gels en-keyword=Coating kn-keyword=Coating en-keyword=Water electrolysis kn-keyword=Water electrolysis en-keyword=Bioactivity kn-keyword=Bioactivity en-keyword=SBF kn-keyword=SBF END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=4 article-no= start-page=337 end-page=343 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=Pneumocephalus with Inverted Papilloma in the Frontoethmoidal Sinus: Case Report and Literature Review en-subtitle= kn-subtitle= en-abstract= kn-abstract=Here, we describe the unique case of a pneumocephalus originating from an inverted papilloma (IP) in the frontoethmoidal sinus. A 71-year-old man with diabetes presented with headaches and altered consciousness. Imaging revealed the pneumocephalus together with bone destruction in the left frontal sinus. He underwent simultaneous endoscopic endonasal and transcranial surgery using an ORBEYE exoscope. Pathological diagnosis of the tumor confirmed IP. Post-surgery, the pneumocephalus was significantly resolved and the squamous cell carcinoma antigen level, which had been elevated, decreased. This case underscores the importance of a multidisciplinary approach and innovative surgical methods in treating complex sinonasal pathologies. en-copyright= kn-copyright=

en-title= kn-title=Virtual indigo carmine chromoendoscopy images: A novel modality for peroral cholangioscopy using artificial intelligence technology (with video) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and Aims: Accurately diagnosing biliary strictures is crucial for surgical decisions, and although peroral cholangioscopy (POCS) aids in visual diagnosis, diagnosing malignancies or determining lesion margins via this route remains challenging. Indigo carmine is commonly used to evaluate lesions during GI endoscopy. We aimed to establish the utility of virtual indigo carmine chromoendoscopy (VICI) converted from POCS images using artificial intelligence.
Methods: This single-center, retrospective study analyzed 40 patients with biliary strictures who underwent POCS using white-light imaging (WLI) and narrow-band imaging (NBI). A cycle-consistent adversarial network was used to convert the WLI into VICI of POCS images. Three experienced endoscopists evaluated WLI, NBI, and VICI via POCS in all patients. The primary outcome was the visualization quality of surface structures, surface microvessels, and lesion margins. The secondary outcome was diagnostic accuracy.
Results: VICI showed superior visualization of the surface structures and lesion margins compared with WLI (P < .001) and NBI (P < .001). The diagnostic accuracies were 72.5%, 87.5%, and 90.0% in WLI alone, WLI and VICI simultaneously, and WLI and NBI simultaneously, respectively. WLI and VICI simultaneously tended to result in higher accuracy than WLI alone (P = .083), and the results were not significantly different from WLI and NBI simultaneously (P = .65).
Conclusions: VICI in POCS proved valuable for visualizing surface structures and lesion margins and contributed to higher diagnostic accuracy comparable to NBI. In addition to NBI, VICI may be a novel supportive modality for POCS. 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=

kn-abstract=The aim of this study is to investigate the relationship of the lipid profile, dysfunctional high-density lipoprotein, ischaemia-modified albumin and thiol–disulfide homeostasis with cognitive impairment, fatigue and sleep disorders in patients with multiple sclerosis. The cognitive functions of patients were evaluated with the Brief International Cognitive Assessment for Multiple Sclerosis battery. Fatigue was evaluated with the Fatigue Severity Scale and the Fatigue Impact Scale. The Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale were used to assess patients’ sleep disturbance. Peripheral blood samples were collected, and lipid levels and myeloperoxidase and paraoxonase activity were measured. The myeloperoxidase/paraoxonase ratio, which indicates dysfunctional high-density lipoprotein, was calculated. Thiol–disulfide homeostasis and ischaemia-modified albumin were measured.
We did not identify any relationship between dysfunctional high-density lipoprotein and the physical disability, cognitive decline, fatigue and sleep problems of multiple sclerosis. Thiol–disulfide homeostasis was associated with cognitive scores. The shift of the balance towards disulfide was accompanied by a decrease in cognitive scores. On the other hand, we did not detect any relationship between fatigue and sleep disorders and thiol–disulfide homeostasis. Our findings revealed a possible correlation between cognitive dysfunction and thiol–disulfide homeostasis in multiple sclerosis patients. en-copyright= kn-copyright= en-aut-name=VuralGonul en-aut-sei=Vural en-aut-mei=Gonul kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=DemirEsra en-aut-sei=Demir en-aut-mei=Esra kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=GumusyaylaSadiye en-aut-sei=Gumusyayla en-aut-mei=Sadiye kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ErenFunda en-aut-sei=Eren en-aut-mei=Funda kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=BarakliSerdar en-aut-sei=Barakli en-aut-mei=Serdar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NeseliogluSalim en-aut-sei=Neselioglu en-aut-mei=Salim kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ErelOzcan en-aut-sei=Erel en-aut-mei=Ozcan kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=2 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=3 en-affil=Department of Neurology, Faculty of Medicine, Ankara Yildirim Beyazit University kn-affil= affil-num=4 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=5 en-affil=Department of Neurology, Ankara City Hospital kn-affil= affil-num=6 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= affil-num=7 en-affil=Department of Clinical Biochemistry, Ankara City Hospital kn-affil= en-keyword=multiple sclerosis kn-keyword=multiple sclerosis en-keyword=dysfunctional HDL kn-keyword=dysfunctional HDL en-keyword=thiol–disulfide homeostasis kn-keyword=thiol–disulfide homeostasis en-keyword=cognitive decline kn-keyword=cognitive decline END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=3 article-no= start-page=e004237 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=Plasma angiotensin-converting enzyme 2 (ACE2) is a marker for renal outcome of diabetic kidney disease (DKD) (U-CARE study 3) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction ACE cleaves angiotensin I (Ang I) to angiotensin II (Ang II) inducing vasoconstriction via Ang II type 1 (AT1) receptor, while ACE2 cleaves Ang II to Ang (1-7) causing vasodilatation by acting on the Mas receptor. In diabetic kidney disease (DKD), it is still unclear whether plasma or urine ACE2 levels predict renal outcomes or not.
Research design and methods Among 777 participants with diabetes enrolled in the Urinary biomarker for Continuous And Rapid progression of diabetic nEphropathy study, the 296 patients followed up for 9 years were investigated. Plasma and urinary ACE2 levels were measured by the ELISA. The primary end point was a composite of a decrease of estimated glomerular filtration rate (eGFR) by at least 30% from baseline or initiation of hemodialysis or peritoneal dialysis. The secondary end points were a 30% increase or a 30% decrease in albumin-to-creatinine ratio from baseline to 1 year.
Results The cumulative incidence of the renal composite outcome was significantly higher in group 1 with lowest tertile of plasma ACE2 (p=0.040). Group 2 with middle and highest tertile was associated with better renal outcomes in the crude Cox regression model adjusted by age and sex (HR 0.56, 95% CI 0.31 to 0.99, p=0.047). Plasma ACE2 levels demonstrated a significant association with 30% decrease in ACR (OR 1.46, 95% CI 1.044 to 2.035, p=0.027) after adjusting for age, sex, systolic blood pressure, hemoglobin A1c, and eGFR.
Conclusions Higher baseline plasma ACE2 levels in DKD were protective for development and progression of albuminuria and associated with fewer renal end points, suggesting plasma ACE2 may be used as a prognosis marker of DKD.Trial registration number UMIN000011525. en-copyright= kn-copyright= en-aut-name=UenoAsami en-aut-sei=Ueno en-aut-mei=Asami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1

en-abstract= kn-abstract=A high-resolution absorption spectrum of the S-1-S-0 transition of free-base phthalocyanine was observed and analyzed with improved reliability. The spectrum, with a partially resolved rotational structure, was obtained by using the buffer-gas cooling technique and a single-mode tunable laser. Our new analysis reveals that the S-1 <- S-0 0(0)(0) band belongs to the a-type transition, where the electronic transition moment aligns parallel to the NH-HN direction, allowing the assignment of the S-1 state to B-1(3u). These results agree with a prior study using supersonic expansion and are well supported by theoretical calculations. Interestingly, the rotational constant B in the S-1 state, which is often smaller than that in the ground state for typical molecules, was found to be slightly larger than that in the S-0 (1)A(g) state. This suggests a change in the character of pi bonds with the electronic excitation. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakayamaNaofumi en-aut-sei=Nakayama en-aut-mei=Naofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=4 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=5 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=6 en-affil=CONFLEX Corporation kn-affil= affil-num=7 en-affil=Molecular Photoscience Research Center, Kobe University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=78 cd-vols= no-issue=2 article-no= start-page=171 end-page=184 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 Relationships among Internalized Stigma, Sense of Coherence, and Personal Recovery of Persons with Schizophrenia Living in the Community en-subtitle= kn-subtitle= en-abstract= kn-abstract=We investigated (i) the relationships among internalized stigma (IS), sense of coherence (SOC), and the personal recovery (PR) of persons with schizophrenia living in the community, and (ii) how to improve the support for these individuals. A questionnaire survey on IS, SOC, and PR was sent by mail to 270 persons with schizophrenia living in the community who were using psychiatric daycare services, of whom 149 responded and 140 were included in the analysis. We established a hypothetical model in which IS influences PR, and SOC influences IS and PR, and we used structural equation modeling to examine the relationships among these concepts. The goodness of fit was acceptable. Our findings suggest that rather than directly promoting PR, SOC promotes PR by mitigating the impact of IS. It is important for nurses/supporters to support individuals with schizophrenia living in the community so that they have opportunities to reflect on their own experiences through their activities and to share their experiences with peers. Nurses/supporters themselves should also reflect on their own support needs. Our findings suggest that this will lead to a reduction of IS and the improvement of SOC, which will in turn promote personal recovery. en-copyright= kn-copyright= en-aut-name=KuramotoAya en-aut-sei=Kuramoto en-aut-mei=Aya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SaitoShinya en-aut-sei=Saito en-aut-mei=Shinya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=WatanabeKumi en-aut-sei=Watanabe en-aut-mei=Kumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=School of Nursing, Faculty of Medicine, Kagawa University kn-affil= en-keyword=schizophrenia kn-keyword=schizophrenia en-keyword=internalized stigma kn-keyword=internalized stigma en-keyword=sense of coherence kn-keyword=sense of coherence en-keyword=personal recovery kn-keyword=personal recovery en-keyword=community kn-keyword=community END start-ver=1.4 cd-journal=joma no-vol=40 cd-vols= no-issue=3 article-no= start-page=560 end-page=577 dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Artificial intelligence to detect noise events in remote monitoring data en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Remote monitoring (RM) of cardiac implantable electrical devices (CIEDs) can detect various events early. However, the diagnostic ability of CIEDs has not been sufficient, especially for lead failure. The first notification of lead failure was almost noise events, which were detected as arrhythmia by the CIED. A human must analyze the intracardiac electrogram to accurately detect lead failure. However, the number of arrhythmic events is too large for human analysis. Artificial intelligence (AI) seems to be helpful in the early and accurate detection of lead failure before human analysis.
Objective: To test whether a neural network can be trained to precisely identify noise events in the intracardiac electrogram of RM data.
Methods: We analyzed 21 918 RM data consisting of 12 925 and 1884 Medtronic and Boston Scientific data, respectively. Among these, 153 and 52 Medtronic and Boston Scientific data, respectively, were diagnosed as noise events by human analysis. In Medtronic, 306 events, including 153 noise events and randomly selected 153 out of 12 692 nonnoise events, were analyzed in a five-fold cross-validation with a convolutional neural network. The Boston Scientific data were analyzed similarly.
Results: The precision rate, recall rate, F1 score, accuracy rate, and the area under the curve were 85.8 ± 4.0%, 91.6 ± 6.7%, 88.4 ± 2.0%, 88.0 ± 2.0%, and 0.958 ± 0.021 in Medtronic and 88.4 ± 12.8%, 81.0 ± 9.3%, 84.1 ± 8.3%, 84.2 ± 8.3% and 0.928 ± 0.041 in Boston Scientific. Five-fold cross-validation with a weighted loss function could increase the recall rate.
Conclusions: AI can accurately detect noise events. AI analysis may be helpful for detecting lead failure events early and accurately. en-copyright= kn-copyright= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei=

Water Intoxication Model en-subtitle= kn-subtitle= en-abstract= kn-abstract=Brain edema causes abnormal fluid retention and can be fatal in severe cases. Although it develops in various diseases, most treatments for brain edema are classical. We analyzed the impacts of age and gender on the characteristics of a water intoxication model that induces pure brain edema in mice and examined the model’s usefulness for research regarding new treatments for brain edema. C57BL/6J mice received an intraperitoneal administration of 10% body weight distilled water, and we calculated the brain water content by measuring the brain-tissue weight immediately after dissection and after drying. We analyzed 8-OHdG and caspase-3 values to investigate the brain damage. We also applied this model in aquaporin 4 knockout (AQP4−) mice and compared these mice with wild-type mice. The changes in water content differed by age and gender, and the 8-OHdG and caspase-3 values differed by age. Suppression of brain edema by AQP4− was also confirmed. These results clarified the differences in the onset of brain edema by age and gender, highlighting the importance of considering the age and gender of model animals. Similar studies using genetically modified mice are also possible. Our findings indicate that this water intoxication model is effective for explorations of new brain edema treatments. en-copyright= kn-copyright= en-aut-name=Nakamura-MaruyamaEmi en-aut-sei=Nakamura-Maruyama en-aut-mei=Emi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IrieKeiichiro en-aut-sei=Irie en-aut-mei=Keiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaritaKazuhiko en-aut-sei=Narita en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HimiNaoyuki en-aut-sei=Himi en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoOsamu en-aut-sei=Miyamoto en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=NakamuraTakehiro en-aut-sei=Nakamura en-aut-mei=Takehiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=2 en-affil=Department of Neurological Surgery, Kagawa University Faculty of Medicine kn-affil= affil-num=3 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=4 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=5 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= affil-num=6 en-affil=Department of Physiology2, Kawasaki Medical School kn-affil= en-keyword=brain edema kn-keyword=brain edema en-keyword=water intoxication model kn-keyword=water intoxication model en-keyword=age kn-keyword=age en-keyword=gender kn-keyword=gender en-keyword=AQP4 kn-keyword=AQP4 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=7 article-no= start-page=595 end-page=603 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230404 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Venetoclax plus low-dose cytarabine in patients with newly diagnosed acute myeloid leukemia ineligible for intensive chemotherapy: an expanded access study in Japan en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: In a Phase 3 international clinical trial (VIALE-C), venetoclax plus low-dose cytarabine improved the response rate and overall survival versus placebo plus low-dose cytarabine in patients with newly diagnosed acute myeloid leukemia who were ineligible for intensive chemotherapy. After the enrollment period of VIALE-C ended, we conducted an expanded access study to provide preapproval access to venetoclax in combination with low-dose cytarabine in Japan.
Methods: Previously, untreated patients with acute myeloid leukemia who were ineligible for intensive chemotherapy were enrolled according to the VIALE-C criteria. Patients received venetoclax (600 mg, Days 1–28, 4-day ramp-up in Cycle 1) in 28-day cycles and low-dose cytarabine (20 mg/m2, Days 1–10). All patients took tumor lysis syndrome prophylactic agents and hydration. Safety endpoints were assessed.
Results: Fourteen patients were enrolled in this study. The median age was 77.5 years (range = 61–84), with 78.6% over 75 years old. The most common grade ≥ 3 treatment-emergent adverse event was neutropenia (57.1%). Febrile neutropenia was the most frequent serious adverse event (21.4%). One patient developed treatment-related acute kidney injury, leading to discontinuation of treatment. Two patients died because of cardiac failure and disease progression that were judged not related to study treatment. No patients developed tumor lysis syndrome.
Conclusions: The safety outcomes were similar to those in VIALE-C without new safety signals and were well managed with standard medical care. In clinical practice, more patients with severe background disease are expected, in comparison with in VIALE-C, suggesting that it is important to carefully manage and prevent adverse events.

workshops and the experience with local teachers- kn-title=ラオスにおける体験型学習を通した教員意識の変容 ―ベンガラ染めワークショップの実践と教員へのインタビューを通じて― en-subtitle= kn-subtitle= en-abstract=The Lao school system calls for the "provision of experiential learning" in all aspects of primary education. However, while hands-on learning is practiced in practical subjects, other subjects remain classroom-based. One of the reasons for this is the teachers' awareness that they do not know how to conduct hands-on learning. In this PBL, we took on the problem consciousness of Laotian teachers in particular regarding class creation and clarified how teachers' consciousness would change through the collaborative implementation of experiential learning in Laos. Specifically, we conducted hands-on workshops at two elementary schools in Laos to dye T-shirts for physical education classes as part of the emotional education program. Teachers were also invited to participate in the bengara-dyeing workshop, and we examined how their awareness was changed through the experience of hands-on learning and collaborative practice. Semi-structured interviews were conducted with teachers at the two schools where the workshop was conducted. The results showed that the teachers viewed the workshop positively in regarding the interaction with foreign visitors and enjoyment and fun through learning. While they understood the potential of experiential learning, some of them did not know how to convert their classroom-based courses to include this form of experiential learning, which is an issue to be addressed in the future. kn-abstract= ラオスの学校制度は, 初等教育全般において「体験型学習の提供」を求めている。実技教科では体験型の授業が実践されているが, それ以外の教科では座学中心の授業である。その背景には, 体験型学習の行い方がわからないといった教員の課題意識がある。本研究では, 特に教員の授業づくりに対する課題意識を引き受け,

as the core of professionalism in Japanese jugyo kenkyu en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
This paper aims to discuss the significance of teacher authorship (jissen kiroku) developed during jugyo kenkyu. Specifically, it explores the structural conditions of jugyo kenkyu that enabled the flourishing of jissen kiroku.

Design/methodology/approach
To find how jissen kiroku developed in jugyo kenkyu, this paper settled triad of authors-text-readers as the analytical perspective. Disputes through 1960s–1980s are adequate to inquire because it can elucidate how readers read jissen kiroku, which is typically challenging to observe.

Findings
Jissen kiroku is a powerful tool for semantically preserving, reconstructing and consolidating professional values and knowledge in jugyo kenkyu with deepening connoisseurship. Voluntary educational research associations (VERAs) encourage teachers to write and read jissen kiroku to develop their professionalism, which also helped develop exclusive semantics within the field. These developments were possible due to the public nature of jissen kiroku, disseminated to lesson study (LS) actors, thereby strengthening discussions both inside and outside VERAs.

Research limitations/implications
The paper proposes shift in views on educational science and emphasizes authorship as authority in that professionalism of teaching can be protected and elevated through authoring.

Originality/value
The significant roles of writing practice have not been explored enough. This paper finds the value of authorship in terms of public nature and openness to all teachers which enable the enhancement of professionalism of the LS field. en-copyright= kn-copyright= en-aut-name=MiyamotoYuichi en-aut-sei=Miyamoto en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= affil-num=1 en-affil=Graduate School of Education, Okayama University kn-affil= en-keyword=Jugyo kenkyu kn-keyword=Jugyo kenkyu en-keyword=Jissen kiroku kn-keyword=Jissen kiroku en-keyword=Authorship kn-keyword=Authorship en-keyword=Voluntary educational research associations kn-keyword=Voluntary educational research associations en-keyword=Semantic preservation and reconstruction kn-keyword=Semantic preservation and reconstruction en-keyword=Connoisseurship kn-keyword=Connoisseurship END start-ver=1.4 cd-journal=joma no-vol=6 cd-vols= no-issue=1 article-no= start-page=013005 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2024 dt-pub=20240103 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Periodic superradiance in an Er:YSO crystal en-subtitle= kn-subtitle= en-abstract= kn-abstract=We observed periodic optical pulses from an Er:YSO crystal during irradiating with a continuous-wave excitation laser. We refer to this phenomenon as "periodic superradiance." This periodicity can be understood qualitatively by a simple model, in which a cyclic process of a continuous supply of population inversion and a sudden burst of superradiance is repeated. The excitation power dependences of peak interval and the pulse area can be interpreted with our simple model. In addition, the linewidth of superradiance is much narrower than an inhomogeneous broadening in a crystal.

We aimed to clarify the clinical significance of a history of GIB in comparison to other factors in patients who had undergone LAAC.
Methods: From October 2019 to September 2023, patients with NVAF who underwent LAAC at our hospital were enrolled. We investigated the percentage of patients with a history of GIB who underwent LAAC and compared the incidence of post-LAAC bleeding in these patients compared to those with other factors.
Results: A total of 45 patients were included. There were 19 patients (42%) with a history of GIB who underwent LAAC. In a Kaplan–Meier analysis, the cumulative incidence of bleeding complications after LAAC was significantly higher in patients with a history of GIB in comparison to patients with other factors. There were eight cases of post-LAAC bleeding in total, and seven cases had GIB.
Conclusions: We need to recognize that GIB is a significant complication in patients who undergo LAAC. The management of GIB by gastroenterologists is essential to the success of LAAC. en-copyright= kn-copyright= en-aut-name=KikuchiTatsuya en-aut-sei=Kikuchi en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei=

kn-title=Syncope and loss of consciousness after implantation of a cardioverter-defibrillator in patients with Brugada syndrome: Prevalence and characteristics in long-term follow-up en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background Syncope is a significant prognostic factor in patients with Brugada syndrome (BrS). However, the risk of ventricular arrhythmia in patients with nonarrhythmic loss of consciousness (LOC) is similar to that in asymptomatic patients. LOC events after implantable cardioverter-defibrillator (ICD) implantation may provide insights into underlying causes of the initial LOC episode.
Objective The purpose of this study was to examine LOC characteristics following ICD implantation.
Methods We retrospectively analyzed 112 patients with BrS (mean age 47 years; 111 men) who were treated with an ICD. The patients were classified into 3 groups based on symptoms at implantation: asymptomatic (35 patients); LOC (46 patients); and ventricular tachyarrhythmia (VTA) (31 patients). We evaluated the incidence and cause of LOC during long-term follow-up after ICD implantation.
Results During mean follow-up of 12.2 years, 41 patients (37%) experienced LOC after ICD implantation. Arrhythmic LOC occurred in 5 asymptomatic patients, 14 LOC patients, and 16 patients with VTA. Nonarrhythmic LOC, similar to the initial episode, occurred after ICD implantation in 6 patients with prior LOC (2 with neurally mediated syncope and 4 with epilepsy). Most epileptic patients experienced LOC during rest or sleeping, and did not show an abnormal encephalogram during initial evaluation of the LOC episodes.
Conclusion After ICD implantation, 13% of patients had nonarrhythmic LOC similar to the initial episode. Accurate classification of LOC based on a detailed medical history is important for risk stratification, although distinguishing arrhythmic LOC from epilepsy-related LOC episodes can be challenging depending on the circumstances and characteristics of the LOC event. en-copyright= kn-copyright= en-aut-name=AsadaSaori en-aut-sei=Asada en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizunoTomofumi en-aut-sei=Mizuno en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasudaTakuro en-aut-sei=Masuda en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UeokaAkira en-aut-sei=Ueoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KawadaSatoshi en-aut-sei=Kawada en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Brugada syndrome kn-keyword=Brugada syndrome en-keyword=Implantable cardioverter-defibrillator kn-keyword=Implantable cardioverter-defibrillator en-keyword=Syncope kn-keyword=Syncope en-keyword=Neurally mediated syncope kn-keyword=Neurally mediated syncope en-keyword=Epilepsy kn-keyword=Epilepsy en-keyword=Ventricular tachyarrhythmia kn-keyword=Ventricular tachyarrhythmia END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue=2 article-no= start-page=307 end-page=316 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231217 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significant delayed conduction and characteristic ventricular tachycardias in patients with cardiac sarcoidosis and electrical storm en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction: Electrical storm (ES) of ventricular tachyarrhythmias (VTAs) is an important cause of sudden death in patients with cardiac sarcoidosis (CS). VTAs in CS are associated with myocardial scarring and inflammation. However, little is known about the risk factors of ES in patients with CS and VTAs. The objective of this study is to clarify the characteristics and risk factors for the development of ES in patients with CS.
Methods: The study population included consecutive 52 patients with CS and sustained VTA. Twenty-five out of 52 patients experienced ES. We evaluated clinical characteristics, imaging modalities, and electrocardiogram (ECG) parameters to determine the risk factors associated with ES.
Results: Half of the patients experienced VTAs as the initial symptom of sarcoidosis, and eight patients had ES as the initial VTA episode. There were no differences in cardiac imaging abnormalities between patients with and without ES. Among ECG markers, significant QRS fragmentation (odds ratio [OR]: 7.9, p = .01) and epsilon waves (OR: 12.24, p = .02) were associated with ES. Among the ventricular tachycardia (VT) characteristics, multiple morphologies of monomorphic VTs (OR: 10.9, p < .01), short VT cycle lengths (OR: 12.5, p < .01), and polymorphic VT (OR: 13.5, p < .01) were associated with ES. Bidirectional VTs were detected in 10 patients with ES and one patient without ES. Immunosuppressive therapy relieved ES in some patients.
Conclusions: ES was common in patients with CS and VTAs. Significant depolarization abnormalities that appeared as QRS fragmentation, epsilon waves, and specific VT characteristics were associated with ES.

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

We investigated the choice of the surgery side for CI (i.e., the better- or poorer-hearing ear) in patients with asymmetric hearing. Audiological records of 74 adults with a unilateral hearing aid who had undergone surgery at Okayama University Hospital were reviewed. The definition of ‘better-hearing ear’ was the aided ear, and the unaided ear was considered the poorer-hearing ear. We performed a multiple regression analysis to identify potential predictors of speech recognition performance after unilateral CI in the patients. Fifty-two patients underwent CI in the poorer-hearing ear. The post-Ci bimodal hearing rate was far higher in the poorer-ear group (77.8% vs. 22.2%). A multivariate analysis revealed that prelingual hearing loss and the patient’s age at CI significantly affected the speech recognition outcome (beta coefficients: 24.6 and −0.33, 95% confidence intervals [11.75-37.45] and [−0.58 to −0.09], respectively), but the CI surgery side did not (−6.76, [−14.92-1.39]). Unilateral CI in the poorer-hearing ear may therefore be a reasonable choice for adult patients with postlingual severe hearing loss, providing a greater opportunity for postoperative bimodal hearing. en-copyright= kn-copyright= en-aut-name=OmichiRyotaro en-aut-sei=Omichi en-aut-mei=Ryotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MaedaYukihide en-aut-sei=Maeda en-aut-mei=Yukihide kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=FukushimaKunihiro en-aut-sei=Fukushima en-aut-mei=Kunihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KataokaYuko en-aut-sei=Kataoka en-aut-mei=Yuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SugayaAkiko en-aut-sei=Sugaya en-aut-mei=Akiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NishizakiKazunori en-aut-sei=Nishizaki en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head and Neck Surgery, Kawasaki Medial University kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Hayashima Clinic of Otolaryngology and Dermatology kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Otolaryngology-Head and Neck Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=cochlear implantation kn-keyword=cochlear implantation en-keyword=poorer hearing ear kn-keyword=poorer hearing ear en-keyword=better hearing ear kn-keyword=better hearing ear en-keyword=hearing aids kn-keyword=hearing aids en-keyword=speech recognition kn-keyword=speech recognition END start-ver=1.4 cd-journal=joma no-vol=184 cd-vols= no-issue= article-no= start-page=9 end-page=30 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20231124 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=How did Educational Scholars in Japan Read Neo-Kantian?

However, it is unclear what threshold percentage of total liver volume drained ('liver drainage rate') significantly improves survival in patients with UMHBO who received systemic chemotherapy.
Objectives: We aimed to assess the optimal liver drainage rate that improves survival in patients with UMHBO receiving chemotherapy using a three-dimensional (3D)-image volume analyzer.
Design: This study was a single-center retrospective cohort study.
Methods: Data from 90 patients with UMHBO who received chemotherapy after endoscopic biliary drainage using metal stents at Okayama University Hospital from January 2003 to December 2020 were reviewed. The liver drainage rate was calculated by dividing the drained liver volume by the total liver volume using a 3D-image volume analyzer. The primary endpoint was overall survival by liver drainage rate. The secondary endpoints were time to recurrent biliary obstruction (TRBO) and prognostic factors.
Results: The median total liver volume was 1172 (range: 673-2032) mL, and the median liver drainage rate was 83% (range: 50-100). Overall survival was 376 (95% CI: 271-450) days, and patients with >80% drainage (n = 67) had significantly longer survival than those with <80% drainage (n = 23) (450 days versus 224 days, p = 0.0033, log-rank test). TRBO was 201 (95% CI: 155-327) days and did not differ significantly by liver drainage rate. Multivariate Cox proportional hazards regression analysis revealed >80% liver drainage [hazard ratio (HR): 0.35, 95% CI: 0.20-0.62, p = 0.0003] and hilar cholangiocarcinoma (HR: 0.30, 95% CI: 0.17-0.50, p < 0.0001) as significant prognostic factors.
Conclusion: In patients with UMHBO scheduled for chemotherapy, >80% drainage is associated with improved survival. Further prospective multicenter studies are needed to verify the results of this study. en-copyright= kn-copyright= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name=

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=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=65 cd-vols= no-issue=8 article-no= start-page=6039 end-page=6055 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220411 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Identification of a Vitamin-D Receptor Antagonist, MeTC7, which Inhibits the Growth of Xenograft and Transgenic Tumors In Vivo en-subtitle= kn-subtitle= en-abstract= kn-abstract=Vitamin-D receptor (VDR) mRNA is overexpressed in neuroblastoma and carcinomas of lung, pancreas, and ovaries and predicts poor prognoses. VDR antagonists may be able to inhibit tumors that overexpress VDR. However, the current antagonists are arduous to synthesize and are only partial antagonists, limiting their use. Here, we show that the VDR antagonist MeTC7 (5), which can be synthesized from 7-dehydrocholesterol (6) in two steps, inhibits VDR selectively, suppresses the viability of cancer cell-lines, and reduces the growth of the spontaneous transgenic TH-MYCN neuroblastoma and xenografts in vivo. The VDR selectivity of 5 against RXRα and PPAR-γ was confirmed, and docking studies using VDR-LBD indicated that 5 induces major changes in the binding motifs, which potentially result in VDR antagonistic effects. These data highlight the therapeutic benefits of targeting VDR for the treatment of malignancies and demonstrate the creation of selective VDR antagonists that are easy to synthesize. en-copyright= kn-copyright= en-aut-name=KhazanNegar en-aut-sei=Khazan en-aut-mei=Negar kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KimKyu Kwang en-aut-sei=Kim en-aut-mei=Kyu Kwang kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HansenJeanne N. en-aut-sei=Hansen en-aut-mei=Jeanne N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SinghNiloy A. en-aut-sei=Singh en-aut-mei=Niloy A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MooreTaylor en-aut-sei=Moore en-aut-mei=Taylor kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SnyderCameron W.

sedation with a target-controlled infusion system during double-balloon endoscopic retrograde cholangiopancreatography en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background The sedation method used during double-balloon endoscopic retrograde cholangiopancreatography (DB-ERCP) differs among countries and/or facilities, and there is no established method. This study aimed to evaluate the efficacy of non-anesthesiologist-administered propofol (NAAP) sedation using a target-controlled infusion (TCI) system during DB-ERCP.
Methods This retrospective study was conducted between May 2017 and December 2020 at an academic center. One hundred and fifty-six consecutive patients who underwent DB-ERCP were sedated by gastroenterologists using diazepam (n = 77) or propofol with a TCI system (n = 79), depending on the period. The primary endpoint was a comparison of poor sedation rates between the two groups. Poor sedation was defined as a condition requiring the use of other sedative agents or discontinuation of the procedure. Secondary endpoints were sedation-related adverse events and risk factors for poor sedation.
Results Poor sedation occurred significantly more often in the diazepam sedation group (diazepam sedation, n = 12 [16%] vs. propofol sedation, n = 1 [1%]; P = 0.001). Vigorous body movements (3 or 4) (diazepam sedation, n = 40 [52%] vs. propofol sedation, n = 28 [35%]; P = 0.038) and hypoxemia (< 85%) (diazepam sedation, n = 7 [9%] vs. propofol sedation, n = 1 [1%]; P = 0.027) occurred significantly more often in the diazepam sedation group. In the multivariate analysis, age < 70 years old (OR, 10.26; 95% CI, 1.57-66.98; P = 0.015), BMI = 25 kg/m2 (OR, 11.96; 95% CI, 1.67-85.69; P = 0.014), and propofol sedation (OR, 0.06; 95% CI, 0.01-0.58; P = 0.015) were associated factors for poor sedation.
Conclusions NAAP sedation with the TCI system during DB-ERCP was safer and more effective than diazepam sedation. en-copyright= kn-copyright= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya 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=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SatoRyosuke en-aut-sei=Sato en-aut-mei=Ryosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OgawaTaiji en-aut-sei=Ogawa en-aut-mei=Taiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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=11 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=12 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=13 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=14 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=15 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital 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= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=15 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=Balloon-assisted endoscopy kn-keyword=Balloon-assisted endoscopy en-keyword=Propofol kn-keyword=Propofol en-keyword=Diazepam kn-keyword=Diazepam en-keyword=Sedation kn-keyword=Sedation END start-ver=1.4 cd-journal=joma no-vol=24 cd-vols= no-issue=8 article-no= start-page=1429 end-page=1438 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220518 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Rationale, design and baseline characteristics of the effect of canagliflozin in patients with type 2 diabetes and microalbuminuria in the Japanese population: The CANPIONE study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aim: To evaluate the effect of canagliflozin, a sodium-glucose co-transporter-2 (SGLT2) inhibitor, on albuminuria and the decline of estimated glomerular filtration rate (eGFR) in participants with type 2 diabetes and microalbuminuria.
Methods: The CANPIONE study is a multicentre, randomized, parallel-group and open-labelled study consisting of a unique 24-week preintervention period, during which the rate of eGFR decline before intervention is estimated, followed by a 52-week intervention and a 4-week washout period. Participants with a geometric mean urinary albumin-to-creatinine ratio (UACR) of 50 and higher and less than 300 mg/g in two consecutive first-morning voids at two different time points, and an eGFR of 45 ml/min/1.73m2 or higher, are randomly assigned to receive canagliflozin 100 mg daily or to continue guideline-recommended treatment, except for SGLT2 inhibitors. The first primary outcome is the change in UACR, and the second primary outcome is the change in eGFR slope.
Results: A total of 258 participants were screened and 98 were randomized at 21 sites in Japan from August 2018 to May 2021. The mean baseline age was 61.4 years and 25.8% were female. The mean HbA1c was 7.9%, mean eGFR was 74.1 ml/min/1.73m2 and median UACR was 104.2 mg/g.
Conclusions: The CANPIONE study will determine whether the SGLT2 inhibitor canagliflozin can reduce albuminuria and slow eGFR decline in participants with type 2 diabetes and microalbuminuria. en-copyright= kn-copyright= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HeerspinkHiddo J.

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background/Aims: Bilateral endoscopic drainage with self-expanding metallic stent (SEMS) can be used to effectively manage hilar malignant biliary obstruction. However, the benefits of using a trisegment drainage method remain unknown.
Methods: This study retrospectively reviewed the data of 125 patients with Bismuth type IIIa or IV unresectable malignant strictures who underwent bilateral endoscopic drainage using SEMSs at four tertiary centers. The patients were divided into the bilateral and trisegment drainage groups for comparison. The primary endpoint was stent patency and the secondary endpoints were technical success, technical and clinical success of reintervention, and overall survival.
Results: The technical success rates of the bilateral and trisegment drainage groups were 95% (34/36) and 90% (80/89) (p=0.41), respectively, with median stent patency durations of 226 and 170 days (p=0.26), respectively. Although the technical success of reintervention was not significantly different between the two groups (p=0.51), the clinical success rate of reintrvention was significantly higher in the trisegment drainage group (73% [11/15] vs 96% [47/49], p=0.009). The median survival times were 324 and 323 days in the bilateral and trisegment drainage groups, respectively (p=0.72). Multivariate Cox hazards model revealed no stent patency-associated factor; however, chemotherapy was associated with longer survival.
Conclusions: Although no significant difference was noted with respect to stent patency, significantly higher clinical success rates were achieved with reintervention using the trisegment drainage method than using the bilateral drainage method alone. en-copyright= kn-copyright= en-aut-name=MatsumotoKazuyuki en-aut-sei=Matsumoto en-aut-mei=Kazuyuki 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=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=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 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology, Tsuyama Central Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology, Iwakuni Medical Center 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=Bile duct obstruction kn-keyword=Bile duct obstruction en-keyword=Neoplasms kn-keyword=Neoplasms en-keyword=Endoscopic biliary drainage kn-keyword=Endoscopic biliary drainage en-keyword=Bilateral drainage kn-keyword=Bilateral drainage en-keyword=Self-expandable metallic stents kn-keyword=Self-expandable metallic stents 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=77 cd-vols= no-issue=4 article-no= start-page=377 end-page=385 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=Disease Progression-Related Markers for Aged Non-Alcoholic Fatty Liver Disease Patients en-subtitle= kn-subtitle= en-abstract= kn-abstract=Liver fibrosis is an important phenomenon in non-alcoholic fatty liver disease (NAFLD) progression. Standard markers reflecting liver fibrosis, including the FIB-4 index, increase with age. This study aimed to identify fibrosis progression-related markers that are diagnostically beneficial even in aged individuals. Serum levels of pro- and anti-inflammatory cytokines were measured by multiple enzyme-linked immunosorbent assay. Two standard NAFLD or fibrosis progression-related markers — the FIB-4 index and APRI score — were analyzed along with cytokine levels to define the best approach to discriminate advanced fibrosis. Ninety-eight NAFLD patients were enrolled: 59 and 39 patients with fibrosis stages 1-2 and 3-4 respectively. In addition to the FIB-4 index and APRI score, the following factors showed significant differences between stages 1-2 and stages 3-4 in a multivariate analysis: platelet counts, IP-10, and RANTES. The fibrosis stage, FIB-4, APRI, PDGF-BB, and RANTES were related to the prognosis. In aged patients, IP-10, GM-CSF, and RANTES differed between stages 1-2 and stages 3-4. FIB-4 and APRI were beneficial for their correlation with fibrosis. However, to stratify either young or elderly advanced fibrosis patients, and to identify patients likely to have a bad outcome, RANTES was the best marker. en-copyright= kn-copyright= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakeuchiYasuto en-aut-sei=Takeuchi en-aut-mei=Yasuto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakakiAkinobu en-aut-sei=Takaki en-aut-mei=Akinobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=WadaNozomu en-aut-sei=Wada en-aut-mei=Nozomu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OyamaAtsushi en-aut-sei=Oyama en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=OnishiHideki en-aut-sei=Onishi en-aut-mei=Hideki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShirahaHidenori en-aut-sei=Shiraha en-aut-mei=Hidenori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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= en-keyword=NAFLD kn-keyword=NAFLD en-keyword=NASH kn-keyword=NASH en-keyword=liver fibrosis kn-keyword=liver fibrosis en-keyword=chemokine kn-keyword=chemokine en-keyword=FIB-4 kn-keyword=FIB-4 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=24 cd-vols= no-issue=14 article-no= start-page=11768 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230721 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Development of Hydrophobic Cell-Penetrating Stapled Peptides as Drug Carriers en-subtitle= kn-subtitle= en-abstract= kn-abstract=Cell-penetrating peptides (CPPs) are widely used for the intracellular delivery of a variety of cargo molecules, including small molecules, peptides, nucleic acids, and proteins. Many cationic and amphiphilic CPPs have been developed; however, there have been few reports regarding hydrophobic CPPs. Herein, we have developed stapled hydrophobic CPPs based on the hydrophobic CPP, TP10, by introducing an aliphatic carbon side chain on the hydrophobic face of TP10. This side chain maintained the hydrophobicity of TP10 and enhanced the helicity and cell penetrating efficiency. We evaluated the preferred secondary structures, and the ability to deliver 5(6)-carboxyfluorescein (CF) as a model small molecule and plasmid DNA (pDNA) as a model nucleotide. The stapled peptide F-3 with CF, in which the stapling structure was introduced at Gly residues, formed a stable & alpha;-helical structure and the highest cell-membrane permeability via an endocytosis process. Meanwhile, peptide F-4 demonstrated remarkable stability when forming a complex with pDNA, making it the optimal choice for the efficient intracellular delivery of pDNA. The results showed that stapled hydrophobic CPPs were able to deliver small molecules and pDNA into cells, and that different stapling positions in hydrophobic CPPs can control the efficiency of the cargo delivery. en-copyright= kn-copyright= en-aut-name=TsuchiyaKeisuke en-aut-sei=Tsuchiya en-aut-mei=Keisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HorikoshiKanako en-aut-sei=Horikoshi en-aut-mei=Kanako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=FujitaMinami en-aut-sei=Fujita en-aut-mei=Minami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiranoMotoharu en-aut-sei=Hirano en-aut-mei=Motoharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoMaho en-aut-sei=Miyamoto en-aut-mei=Maho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YokooHidetomo en-aut-sei=Yokoo en-aut-mei=Hidetomo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=DemizuYosuke en-aut-sei=Demizu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=2 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=3 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=4 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=5 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=6 en-affil=Division of Organic Chemistry, National Institute of Health Sciences kn-affil= affil-num=7 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=cell-penetrating peptide kn-keyword=cell-penetrating peptide en-keyword=stapled peptide kn-keyword=stapled peptide en-keyword=hydrophobic peptide kn-keyword=hydrophobic peptide en-keyword=helical structure kn-keyword=helical structure en-keyword=plasmid DNA delivery kn-keyword=plasmid DNA delivery END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=10 article-no= start-page=e028706 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230516 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significant Delayed Activation on the Right Ventricular Outflow Tract Represents Complete Right Bundle-Branch Block Pattern in Brugada Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: The appearance of complete right bundle-branch block (CRBBB) in Brugada syndrome (BrS) is associated with an increased risk of ventricular fibrillation. The pathophysiological mechanism of CRBBB in patients with BrS has not been well established. We aimed to clarify the significance of a conduction delay zone associated with arrhythmias on CRBBB using body surface mapping in patients with BrS.
Methods and Results: Body surface mapping was recorded in 11 patients with BrS and 8 control patients both with CRBBB. CRBBB in control patients was transiently exhibited by unintentional catheter manipulation (proximal RBBB). Ventricular activation time maps were constructed for both of the groups. We divided the anterior chest into 4 areas (inferolateral right ventricle [RV], RV outflow tract [RVOT], intraventricular septum, and left ventricle) and compared activation patterns between the 2 groups. Excitation propagated to the RV from the left ventricle through the intraventricular septum with activation delay in the entire RV in the control group (proximal RBBB pattern). In 7 patients with BrS, excitation propagated from the inferolateral RV to the RVOT with significant regional activation delay. The remaining 4 patients with BrS showed a proximal RBBB pattern with the RVOT activation delay. The ventricular activation time in the inferolateral RV was significantly shorter in patients with BrS without a proximal RBBB pattern than in control patients.
Conclusions: The CRBBB morphology in patients with BrS consisted of 2 mechanisms: (1) significantly delayed conduction in the RVOT and (2) proximal RBBB with RVOT conduction delay. Significant RVOT conduction delay without proximal RBBB resulted in CRBBB morphology in patients with BrS. en-copyright= kn-copyright= en-aut-name=MorimotoYoshimasa en-aut-sei=Morimoto en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EjiriKentaro en-aut-sei=Ejiri en-aut-mei=Kentaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MizunoTomofumi en-aut-sei=Mizuno en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MasudaTakuro en-aut-sei=Masuda en-aut-mei=Takuro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UeokaAkira en-aut-sei=Ueoka en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=AsadaSaori en-aut-sei=Asada en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=KawadaSatoshi en-aut-sei=Kawada en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Therapeutics , Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Cardiovascular Therapeutics , Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= affil-num=13 en-affil=Department of Cardiovascular Medicine ,Okayama University Graduate School of Medicine, Dentistry, Pharmaceutical Sciences kn-affil= en-keyword=activation pattern kn-keyword=activation pattern en-keyword=body surface map kn-keyword=body surface map en-keyword=Brugada syndrome kn-keyword=Brugada syndrome en-keyword=complete right bundle-branch block kn-keyword=complete right bundle-branch block END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=3 article-no= start-page=331 end-page=334 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=Endobronchial Metastasis with Bloody Sputum 20 Years after Complete Resection of type A Non-Invasive Thymoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Masaoka stage I type A thymomas rarely recur. We report the case of an 82-year-old man who developed endobronchial metastasis after thymothymectomy for Masaoka stage I type A thymoma. Twenty years after surgery, the patient developed bloody sputum, and chest computed tomography revealed a neoplasm obstructing the right upper lobe bronchus of the lung with enlarged mediastinal lymph nodes. He underwent right upper lobectomy and mediastinal lymph node dissection. Although preoperative pathological diagnosis was squamous cell carcinoma of the lung, postoperative histopathology revealed endobronchial metastasis of the thymoma. Nine years later, at age 89, the patient is alive and well. en-copyright= kn-copyright= en-aut-name=WatanabeMototsugu en-aut-sei=Watanabe en-aut-mei=Mototsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 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=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= 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= en-keyword=endobronchial metastasis kn-keyword=endobronchial metastasis en-keyword=type A thymoma kn-keyword=type A thymoma en-keyword=bloody sputum kn-keyword=bloody sputum END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=5 article-no= start-page=193 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=20230426 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Diagnostic Performance of Cardiac Computed Tomography for Detecting Patent Foramen Ovale: Evaluation Using Transesophageal Echocardiography and Catheterization as Reference Standards en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Patent foramen ovale (PFO) is associated with various diseases such as cryptogenic stroke, migraine, and platypnea-orthodeoxia syndrome. This study aimed to evaluate the diagnostic performance of cardiac computed tomography (CT) for PFO detection. Materials and Methods: Consecutive patients diagnosed with atrial fibrillation and who underwent catheter ablation with pre-procedural cardiac CT and transesophageal echocardiography (TEE) were enrolled in this study. The presence of PFO was defined as (1) the confirmation of PFO using TEE and/or (2) the catheter crossing the interatrial septum (IAS) into the left atrium during ablation. CT findings indicative of PFO included (1) the presence of a channel-like appearance (CLA) on the IAS and (2) a CLA with a contrast jet flow from the left atrium to the right atrium. The diagnostic performance of both a CLA alone and a CLA with a jet flow was evaluated for PFO detection. Results: Altogether, 151 patients were analyzed in the study (mean age, 68 years; men, 62%). Twenty-nine patients (19%) had PFO confirmed by TEE and/or catheterization. The diagnostic performance of a CLA alone was as follows: sensitivity, 72.4%; specificity, 79.5%; positive predictive value (PPV), 45.7%; negative predictive value (NPV), 92.4%. The diagnostic performance of a CLA with a jet flow was as follows: sensitivity, 65.5%; specificity, 98.4%; PPV, 90.5%; NPV, 92.3%. The diagnostic performance of a CLA with a jet flow was statistically superior to that of a CLA alone (p = 0.045), and the C-statistics were 0.76 and 0.82, respectively. Conclusion: A CLA with a contrast jet flow in cardiac CT has a high PPV for PFO detection, and its diagnostic performance is superior to that of a CLA alone. en-copyright= kn-copyright=

of Doppler effects in a cryogenic buffer-gas cell en-subtitle= kn-subtitle= en-abstract= kn-abstract=Buffer-gas cooling is a universal cooling technique for molecules and used for various purposes. One of its ap- plications is using molecules inside a buffer-gas cell for low-temperature spectroscopy. Although a high-intensity signal is expected in the cell, complex molecular dynamics is a drawback for precise spectroscopy. In this study, we performed high-resolution absorption spectroscopy of low -J transitions in the òΠ(0, 0, 0)-˜X²Σ+(0, 0, 0) band of calcium monohydroxide (CaOH). CaOH molecules were produced by laser ablation in a copper cell and cooled to ∼5 K using helium buffer gas. We probed the Doppler effects in a buffer-gas cell by injecting counterpropagating lasers inside the cell. The time evolutions of the Doppler width and shift were simulated using a dedicated Monte Carlo simulation and compared with data. en-copyright= kn-copyright= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TakahashiYuiki en-aut-sei=Takahashi en-aut-mei=Yuiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TobaruReo en-aut-sei=Tobaru en-aut-mei=Reo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Kyoto University kn-affil= affil-num=3 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=4 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=5 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=6 en-affil=Division of Physics, Mathematics, and Astronomy, California Institute of Technology kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=29 cd-vols= no-issue=5 article-no= start-page=523 end-page=526 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202305 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Buruli ulcer caused by Mycobacterium ulcerans subsp. shinshuense: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Buruli ulcer is the third most common mycobacterial infection worldwide and is mainly diagnosed in tropical regions. Globally, this progressive disease is caused by Mycobacterium ulcerans; however, Mycobacterium ulcerans subsp. shinshuense, an Asian variant, has been exclusively identified in Japan. Because of insufficient clinical cases, the clinical features of M. ulcerans subsp. shinshuense–associated Buruli ulcer remain unclear. A 70-year-old Japanese woman presented with erythema on her left backhand. The skin lesion deteriorated without an apparent etiology of inflammation, and she was referred to our hospital 3 months after disease onset. A biopsy specimen was incubated in 2% Ogawa medium at 30 °C. After 66 days, we detected small yellow-pigmented colonies, suggesting scotochromogens. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI Biotyper; Bruker Daltonics, Billerica, MA, USA) indicated that the organism was Mycobacterium pseudoshottsii or Mycobacterium marinum. However, additional PCR testing for the insertion sequence 2404 (IS2404) was positive, suggesting that the pathogen was either M. ulcerans or M. ulcerans subsp. shinshuense. Further examination by 16S rRNA sequencing analysis, focusing on nucleotide positions 492, 1247, 1288, and 1449–1451, we finally identified the organism as M. ulcerans subsp. shinshuense. The patient was successfully treated with 12 weeks of clarithromycin and levofloxacin treatment. Mass spectrometry is the latest microbial diagnostic method; however, it cannot be used to identify M. ulcerans subsp. shinshuense. To accurately detect this enigmatic pathogen and uncover its epidemiology and clinical characteristics in Japan, more accumulation of clinical cases with accurate identification of the causative pathogen is essential. en-copyright= kn-copyright= en-aut-name=FujimoriTakumi en-aut-sei=Fujimori en-aut-mei=Takumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=IioKoji en-aut-sei=Iio en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=MiyamotoYuji en-aut-sei=Miyamoto en-aut-mei=Yuji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HoshinoYoshihiko en-aut-sei=Hoshino en-aut-mei=Yoshihiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=KakehiAyaka en-aut-sei=Kakehi en-aut-mei=Ayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OkuraMami en-aut-sei=Okura en-aut-mei=Mami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MinabeHiroshi en-aut-sei=Minabe en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=YokoyamaYukika en-aut-sei=Yokoyama en-aut-mei=Yukika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=HigashikageAkihito en-aut-sei=Higashikage en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital 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=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Dermatology, Shimane University Faculty of Medicine kn-affil= affil-num=5 en-affil=Department of Mycobacteriology, Leprosy Research Center, National Institute of Infectious Diseases kn-affil= affil-num=6 en-affil=Department of Mycobacteriology, Leprosy Research Center, National Institute of Infectious Diseases kn-affil= affil-num=7 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=8 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=9 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=10 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Microbiology Division, Clinical Laboratory, Okayama University Hospital kn-affil= en-keyword=Buruli ulcer kn-keyword=Buruli ulcer en-keyword=Mycobacterium ulcerans kn-keyword=Mycobacterium ulcerans en-keyword=Mycobacterium ulcerans subsp kn-keyword=Mycobacterium ulcerans subsp en-keyword=shinshuense kn-keyword=shinshuense en-keyword=16S rRNA sequencing analysis kn-keyword=16S rRNA sequencing analysis END start-ver=1.4 cd-journal=joma no-vol=77 cd-vols= no-issue=2 article-no= start-page=199 end-page=201 dt-received= dt-revised= dt-accepted= dt-pub-year=2023 dt-pub=202304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Urinary Retention Suggesting Aseptic Meningitis: Meningitis-Retention Syndrome Without Physical Signs of Meningeal Irritation en-subtitle= kn-subtitle= en-abstract= kn-abstract=Meningitis-retention syndrome (MRS) is the combination of aseptic meningitis and acute urinary retention that occurs in the absence of other neurological diseases.

Bisphosphonates are prescribed to treat secondary osteoporosis in patients with rheumatoid arthritis (RA). We recently encountered two unusual cases of intraoral ONJ in RA patients who had not been treated with a BMA and did not have features of methotrexate- associated lymphoproliferative disorder. Their ONJ stage II bone exposures were treated by conservative therapy, providing good prognoses. These cases indicate that ONJ can occur in RA patients not treated with bisphosphonates.

The aim of this study was to evaluate the differences in LAA morphology according to the types of atrial fibrillation (AF). A total of 299 patients (mean age: 67 +/- 13 years) who underwent transesophageal echocardiography (TEE) were included. Patients were classified into non-AF (n = 64), paroxysmal AF (n = 86), persistent AF (n = 87), or long-standing persistent AF (n = 62). LAA morphology, including LAA ostial diameter and depth, was assessed using TEE. Patients with long-standing persistent AF had larger LAA ostial diameter and depth and lower LAA flow velocity. The maximum LAA ostial diameter was 19 +/- 4 mm in patients with non-AF, 21 +/- 4 mm in patients with paroxysmal AF, 23 +/- 5 mm in patients with persistent AF, and 26 +/- 5 mm in patients with long-standing persistent AF. LAA ostial diameter was increased by 2 or 3 mm with the progression of AF. LAA ostial diameter was correlated with LA volume index (R = 0.37, P < 0.01) and the duration of continuous AF (R = 0.30, P < 0.01), but not with age or the period from the onset of AF. In conclusion, LAA size was increased with the progression of AF. en-copyright= kn-copyright= en-aut-name=TakayaYoichi en-aut-sei=Takaya en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NakayamaRie en-aut-sei=Nakayama en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=YokohamaFumi en-aut-sei=Yokohama en-aut-mei=Fumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TohNorihisa en-aut-sei=Toh en-aut-mei=Norihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=48 article-no= start-page=e31868 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221202 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endoscopic treatment for duodenal perforation due to biliary stent dislocation: A case report and brief review of the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Rationale:Duodenal wall perforation by a dislocated biliary stent placed for biliary structure is rare but can be life-threatening. There are few reports on the management of stent-related duodenal perforation. Patient concerns:Three cases included in this study had undergone endoscopic retrograde cholangiopancreatography with placement of a plastic stent for biliary stricture. Two cases had symptoms (fever or abdominal pain), while other case showed no symptom after biliary stent placement. Diagnoses:Dislocation of plastic stents was revealed on computed tomography or endoscopic images. Two patients were diagnosed with duodenal perforation due to distal migration of long stents with a straight shape on the distal side. One patient was diagnosed with fistula formation between the intrahepatic bile duct and duodenum due to perforation of a pigtail stent. Interventions:All cases could successfully be managed endoscopically with closure by hemoclips or stent replacement. Outcomes:All 3 cases were improved after endoscopic treatment without any subsequent intervention. Lessons:Longer stents with a straight distal side are associated with a higher risk of duodenal perforation. Endoscopic management is appropriate as a first-line approach for a clinically stable patient. At the time of stent placement, we should pay attention to the length and type of stent. en-copyright= kn-copyright= en-aut-name=FujiiYuki en-aut-sei=Fujii en-aut-mei=Yuki 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=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=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=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari 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 Science kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=biliary stent kn-keyword=biliary stent en-keyword=endoscope kn-keyword=endoscope en-keyword=migration kn-keyword=migration en-keyword=perforation kn-keyword=perforation END start-ver=1.4 cd-journal=joma no-vol=5 cd-vols= no-issue=1 article-no= start-page=161 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221129 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=High-resolution spectroscopy of buffer-gas-cooled phthalocyanine en-subtitle= kn-subtitle= en-abstract= kn-abstract=For over five decades, studies in the field of chemical physics and physical chemistry have primarily aimed to understand the quantum properties of molecules. However, high-resolution rovibronic spectroscopy has been limited to relatively small and simple systems because translationally and rotationally cold samples have not been prepared in sufficiently large quantities for large and complex systems. In this study, we present high-resolution rovibronic spectroscopy results for large gas-phase molecules, namely, free-base phthalocya-nine (FBPc). The findings suggest that buffer-gas cooling may be effective for large molecules introduced via laser ablation. High-resolution electronic spectroscopy, combined with other experimental and theoretical studies, will be useful in understanding the quantum properties of molecules. These findings also serve as a guide for quantum chemical calculations of large molecules. en-copyright= kn-copyright= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TobaruReo en-aut-sei=Tobaru en-aut-mei=Reo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TakahashiYuiki en-aut-sei=Takahashi en-aut-mei=Yuiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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 Physics, Mathematics, and Astronomy, California Institute of Technology kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=6 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=7 en-affil=5Department of Physics, University of Toyama kn-affil= affil-num=8 en-affil=Molecular Photoscience Research Center, Kobe University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=31 article-no= start-page=11607 end-page=11616 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=2022116 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Gastric linitis plastica with autoimmune pancreatitis diagnosed by an endoscopic ultrasonography-guided fine-needle biopsy: A case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=BACKGROUND
Gastric linitis plastica (GLP) is a subset of gastric cancer with a poor prognosis. It is difficult to obtain a definitive diagnosis by endoscopic mucosal biopsies, and the usefulness of an endoscopic ultrasonography-guided fine-needle biopsy (EUS-FNB) for GLP has been recently reported. Meanwhile, autoimmune diseases are occasionally known to coexist with malignant tumors as paraneoplastic syndrome. We herein report the usefulness of an EUS-FNB for detecting GLP and the possibility of paraneoplastic syndrome coexisting with GLP.

CASE SUMMARY
An 81-year-old man was admitted to our hospital for a 1-mo history of epigastric pain that increased after eating. His laboratory data revealed high levels of serum carbohydrate antigen 19-9 and immunoglobulin-G4. Endoscopic examinations showed giant gastric folds and reddish mucosa; however, no epithelial changes were observed. The gastric lumen was not distensible by air inflation, suggesting GLP. Computed tomography showed the thickened gastric wall, the diffuse enlargement of the pancreas, and the peripancreatic rim, which suggested autoimmune pancreatitis (AIP) coexisting with GLP. Because the pathological findings of the endoscopic biopsy showed no malignancy, he underwent an EUS-FNB and was diagnosed with GLP. He received chemotherapy for unresectable gastric cancer due to peritoneal metastasis, after which both the gastric wall thickening and diffuse enlargement of the pancreas were improved.

CONCLUSION
An EUS-FNB for GLP with a negative endoscopic biopsy is useful, and AIP may develop as a paraneoplastic syndrome. 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=KanzakiHiromitsu en-aut-sei=Kanzaki en-aut-mei=Hiromitsu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorimotoKosaku en-aut-sei=Morimoto en-aut-mei=Kosaku kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TerasawaHiroyuki en-aut-sei=Terasawa en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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=11 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=12 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=13 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil= kn-affil= affil-num=13 en-affil=Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=Endoscopic ultrasound-guided fine needle aspiration kn-keyword=Endoscopic ultrasound-guided fine needle aspiration en-keyword=Linitis plastica kn-keyword=Linitis plastica en-keyword=Autoimmune pancreatitis kn-keyword=Autoimmune pancreatitis en-keyword=Paraneoplastic syndromes kn-keyword=Paraneoplastic syndromes en-keyword=Case report kn-keyword=Case report END start-ver=1.4 cd-journal=joma no-vol=14 cd-vols= no-issue=2 article-no= start-page=205 end-page=220 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20221029 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Suramin prevents the development of diabetic kidney disease by inhibiting NLRP3 inflammasome activation in KK-Ay mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction Nucleotide-binding oligomerization domain-like receptor family pyrin domain containing 3 (NLRP3) inflammasomes produce IL-18 upon being activated by various stimuli via the P2 receptors. Previously, we showed that serum and urine IL-18 levels are positively associated with albuminuria in patients with type 2 diabetes, indicating the involvement of inflammasome activation in the pathogenesis of diabetic kidney disease (DKD). In the present study, we investigated whether the administration of suramin, a nonselective antagonist of the P2 receptors, protects diabetic KK.Cg-A(y)/TaJcl (KK-Ay) mice against DKD progression. Materials and Methods Suramin or saline was administered i.p. to KK-Ay and C57BL/6J mice once every 2 weeks for a period of 8 weeks. Mouse mesangial cells (MMCs) were stimulated with ATP in the presence or absence of suramin. Results Suramin treatment significantly suppressed the increase in the urinary albumin-to-creatinine ratio, glomerular hypertrophy, mesangial matrix expansion, and glomerular fibrosis in KK-Ay mice. Suramin also suppressed the upregulation of NLRP3 inflammasome-related genes and proteins in the renal cortex of KK-Ay mice. P2X4 and P2X7 receptors were significantly upregulated in the isolated glomeruli of KK-Ay mice and mainly distributed in the glomerular mesangial cells of KK-Ay mice. Although neither ATP nor suramin affected NLRP3 expression in MMCs, suramin inhibited ATP-induced NLRP3 complex formation and the downstream expression of caspase-1 and IL-18 in MMCs. Conclusions These results suggest that the NLRP3 inflammasome is activated in a diabetic kidney and that inhibition of the NLRP3 inflammasome with suramin protects against the progression of early stage DKD. en-copyright= kn-copyright= en-aut-name=OdaKaori en-aut-sei=Oda en-aut-mei=Kaori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KoderaRyo en-aut-sei=Kodera en-aut-mei=Ryo 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=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi 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=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=3 en-affil=Osafune Clinic kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism kn-affil= affil-num=5 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= en-keyword=Diabetic kidney disease kn-keyword=Diabetic kidney disease en-keyword=Inflammasomes kn-keyword=Inflammasomes en-keyword=Suramin kn-keyword=Suramin END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=5 article-no= start-page=609 end-page=615 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Idiopathic Pneumonia Syndrome Refractory to Ruxolitinib after Post-Transplant Cyclophosphamide-based Haploidentical Hematopoietic Stem Cell Transplantation: Lung Pathological Findings from an Autopsy Case en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 69-year-old Japanese man with acute leukemia received post-transplant cyclophosphamide-based haploidentical stem cell transplantation (PTCY-haplo-SCT) but was readmitted with dyspnea and ground-glass-opacities of the lungs. Bronchoscopy showed inflammatory changes with no signs of infection. He received steroids but required intubation as his condition deteriorated. In addition to antithymocyte globulin and cyclophosphamide, we administered ruxolitinib but failed to save him. Autopsy findings revealed fibrotic nonspecific interstitial pneumonia (NSIP) without evidence of organizing pneumonia or infection. Thus, we diagnosed idiopathic pneumonia syndrome (IPS). As far as our knowledge, this is the first case of IPS with NSIP histology after PTCY-haplo-SCT. en-copyright= kn-copyright= en-aut-name=MatsumotoKen en-aut-sei=Matsumoto en-aut-mei=Ken kn-aut-name=

as Non-Retroviral Endogenous Viral Elements en-subtitle= kn-subtitle= en-abstract= kn-abstract=Eukaryotic genomes contain numerous copies of endogenous viral elements (EVEs), most of which are considered endogenous retrovirus (ERV) sequences. Over the past decade, non-retroviral endogenous viral elements (nrEVEs) derived from ancient RNA viruses have been discovered. Several functions have been proposed for these elements, including antiviral defense. This review summarizes the current understanding of nrEVEs derived from RNA viruses, particularly endogenous bornavirus-like elements (EBLs) and endogenous filovirus-like elements (EFLs). EBLs are one of the most extensively studied nrEVEs. The EBL derived from bornavirus nucleoprotein (EBLN) is thought to function as a non-coding RNA or protein that regulates host gene expression or inhibits virus propagation. Ebolavirus and marburgvirus, which are filoviruses, induce severe hemorrhagic fever in humans and nonhuman primates. Although the ecology of filoviruses remains unclear, bats are believed to be potential reservoirs. Based on the knowledge from EBLs, it is postulated that EFLs in the bat genome help to maintain the balance between filovirus infection and the bat’s defense system, which may partially explain why bats act as potential reservoirs. Further research into the functions of nrEVEs could reveal novel antiviral systems and inspire novel antiviral approaches. en-copyright= kn-copyright= en-aut-name=OgawaHirohito en-aut-sei=Ogawa en-aut-mei=Hirohito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HondaTomoyuki en-aut-sei=Honda en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Virology, Faculty of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=EVE kn-keyword=EVE en-keyword=nrEVE kn-keyword=nrEVE en-keyword=bornavirus kn-keyword=bornavirus en-keyword=filovirus kn-keyword=filovirus en-keyword=antiviral kn-keyword=antiviral END start-ver=1.4 cd-journal=joma no-vol=936 cd-vols= no-issue=2 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202291 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Low-J Transitions in A˜2Π(0,0,0)−X˜2Σ+(0,0,0) Band of Buffer-gas-cooled CaOH en-subtitle= kn-subtitle= en-abstract= kn-abstract=Calcium monohydroxide radical (CaOH) is receiving an increasing amount of attention from the astrophysics community as it is expected to be present in the atmospheres of hot rocky super-Earth exoplanets as well as interstellar and circumstellar environments. Here, we report the high-resolution laboratory absorption spectroscopy on low-J transitions in A ˜ 2 Π ( 0 , 0 , 0 ) X ˜ 2 Σ + ( 0 , 0 , 0 ) band of buffer-gas-cooled CaOH. In total, 40 transitions out of the low-J states were assigned, including 27 transitions that have not been reported in previous literature. The determined rotational constants for both ground and excited states are in excellent agreement with previous literature, and the measurement uncertainty for the absolute transition frequencies was improved by more than a factor of 3. This will aid future interstellar, circumstellar, and atmospheric identifications of CaOH. The buffer-gas-cooling method employed here is a particularly powerful method to probe low-J transitions and is easily applicable to other astrophysical molecules. en-copyright= kn-copyright= en-aut-name=TakahashiYuiki en-aut-sei=Takahashi en-aut-mei=Yuiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=BabaMasaaki en-aut-sei=Baba en-aut-mei=Masaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=EnomotoKatsunari en-aut-sei=Enomoto en-aut-mei=Katsunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HiramotoAyami en-aut-sei=Hiramoto en-aut-mei=Ayami kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwakuniKana en-aut-sei=Iwakuni en-aut-mei=Kana kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KumaSusumu en-aut-sei=Kuma en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TobaruReo en-aut-sei=Tobaru en-aut-mei=Reo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Division of Physics, Mathematics, and Astronomy, California Institute of Technology kn-affil= affil-num=2 en-affil=Department of Chemistry, Graduate School of Science, Kyoto University kn-affil= affil-num=3 en-affil=Department of Physics, University of Toyama kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Institute for Laser Science, University of Electro-Communications kn-affil= affil-num=6 en-affil=Atomic, Molecular and Optical Physics Laboratory, RIKEN kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=76 cd-vols= no-issue=3 article-no= start-page=333 end-page=338 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=202206 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Successful Treatment of Atypical Femoral Fracture with Bowed Femur Using Contralateral Intramedullary Nail Combined with Early Daily Teriparatide en-subtitle= kn-subtitle= en-abstract= kn-abstract=We report a case of atypical femoral fracture achieving early fracture union with combination therapy comprising contralateral nail and immediate teriparatide injection.

Vaccination against measles, mumps, rubella, and varicella zoster (VZV) (MMRV) is therefore recommended for hematopoietic stem cell transplantation (HCT) recipients. However, studies on adult HCT recipients with VPD infections are limited. At our institution, we have systematically conducted serological MMRV tests as a part of check-up examinations during long-term follow-up (LTFU) after HCT since 2015. This retrospective study aimed to evaluate changes in the serostatus between before and 2 years after allogeneic HCT. Among 161 patients, the pre-transplant seropositivity was 82.7% for measles, 86.8% for mumps, 84.2% for rubella, and 94.3% for VZV. Among 56 patients who underwent LTFU including serological MMRV tests at 2 years after HCT, the percentages maintaining seroprotective antibody levels for measles, mumps, rubella and VZV were 71.5% (40/56), 51.8% (29/56), 48.2% (27/56), and 60.7% (34/56), respectively. Vaccination was recommended for 22 patients, and 12 were vaccinated. Among the 12 vaccinated patients, rates of seroconversion were examined in 2-6 patients for each of the four viruses. They were 100% (3/3) for measles, 33.3% (1/3) for mumps, 50% (3/6) for rubella, and 0% (0/2) for VZV. Further studies are warranted to clarify the effect of vaccination in adult HCT recipients. en-copyright= kn-copyright= en-aut-name=YoshidaShohei en-aut-sei=Yoshida en-aut-mei=Shohei kn-aut-name=

S-Cationization to Evaluate Antigen Spreading en-subtitle= kn-subtitle= en-abstract= kn-abstract=Serum autoantibody to cancer/testis antigens (CTAs) is a critical biomarker that reflects the antitumor immune response. Quantitative and multiplexed anti-CTA detection arrays can assess the immune status in tumors and monitor therapy-induced antitumor immune reactions. Most full-length recombinant CTA proteins tend to aggregate. Cysteine residue-specific S-cationization techniques facilitate the preparation of water-soluble and full-length CTAs. Combined with Luminex technology, we designed a multiple S-cationized antigen-immobilized bead array (MUSCAT) assay system to evaluate multiple serum antibodies to CTAs. Reducible S-alkyl-disulfide-cationized antigens in cytosolic conditions were employed to develop rabbit polyclonal antibodies as positive controls. These control antibodies sensitively detected immobilized antigens on beads and endogenous antigens in human lung cancer-derived cell lines. Rabbit polyclonal antibodies successfully confirmed the dynamic ranges and quantitative MUSCAT assay results. An immune monitoring study was conducted using the serum samples on an adenovirus-mediated REIC/Dkk-3 gene therapy clinical trial that showed a successful clinical response in metastatic castration-resistant prostate cancer. Autoantibody responses were closely related to clinical outcomes. Notably, upregulation of anti-CTA responses was monitored before tumor regression. Thus, quantitative monitoring of anti-CTA antibody biomarkers can be used to evaluate the cancer-immunity cycle. A quality-certified serum autoantibody monitoring system is a powerful tool for developing and evaluating cancer immunotherapy. en-copyright= kn-copyright= en-aut-name=MiyamotoAi en-aut-sei=Miyamoto en-aut-mei=Ai kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HonjoTomoko en-aut-sei=Honjo en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MasuiMirei en-aut-sei=Masui en-aut-mei=Mirei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KinoshitaRie en-aut-sei=Kinoshita en-aut-mei=Rie kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KumonHiromi en-aut-sei=Kumon en-aut-mei=Hiromi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=KakimiKazuhiro en-aut-sei=Kakimi en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=FutamiJunichiro en-aut-sei=Futami en-aut-mei=Junichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= affil-num=1 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=2 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=3 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= affil-num=4 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Innovation Center Okayama for Nanobio-targeted Therapy, Okayama University kn-affil= affil-num=6 en-affil=Department of Immunotherapeutics, The University of Tokyo Hospital kn-affil= affil-num=7 en-affil=Department of Interdisciplinary Science and Engineering in Health Systems, Okayama University kn-affil= en-keyword=autoantibody kn-keyword=autoantibody en-keyword=biomarker kn-keyword=biomarker en-keyword=protein engineering kn-keyword=protein engineering en-keyword=cancer-immunity cycle kn-keyword=cancer-immunity cycle en-keyword=immune monitoring kn-keyword=immune monitoring en-keyword=cancer kn-keyword=cancer en-keyword=testis antigens kn-keyword=testis antigens END start-ver=1.4 cd-journal=joma no-vol=101 cd-vols= no-issue=7 article-no= start-page=e28872 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220218 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Silica-associated systemic lupus erythematosus with lupus nephritis and lupus pneumonitis A case report and a systematic review of the literature en-subtitle= kn-subtitle= en-abstract= kn-abstract=Introduction Several epidemiological studies have shown that silica exposure triggers the onset of systemic lupus erythematosus (SLE); however, the clinical characteristics of silica-associated SLE have not been well studied. Patient concerns A 67-year-old man with silicosis visited a primary hospital because of a fever and cough. His respiratory condition worsened, regardless of antibiotic medication, and he was referred to our hospital. Diagnosis The patient showed leukopenia, lymphopenia, serum creatinine elevation with proteinuria and hematuria, decreased serum C3 level, and was positive for anti-double stranded DNA antibody, anti-nuclear antibody, and direct Coombs test. He was diagnosed with SLE. Renal biopsy was performed, and the patient was diagnosed with lupus nephritis (class IV-G(A/C) + V defined by the International Society of Nephrology/Renal Pathology Society classification). Computed tomography revealed acute interstitial pneumonitis, bronchoalveolar lavage fluid showed elevation of the lymphocyte fraction, and he was diagnosed with lupus pneumonitis. Interventions Prednisolone (50 mg/day) with intravenous cyclophosphamide (500 mg/body) were initiated. Outcomes The patient showed a favorable response to these therapies. He was discharged from our hospital and received outpatient care with prednisolone slowly tapered off. He had cytomegalovirus and herpes zoster virus infections during treatment, which healed with antiviral therapy. Review: We searched for the literature on sSLE, and selected 11 case reports and 2 population-based studies. The prevalence of SLE manifestations in sSLE patients were comparative to that of general SLE, particularly that of elderly-onset SLE. Our renal biopsy report and previous reports indicate that lupus nephritis of sSLE patients show as various histological patterns as those of general SLE patients. Among the twenty sSLE patients reported in the case articles, three patients developed lupus pneumonitis and two of them died of it. Moreover, two patients died of bacterial pneumonia, one developed aspergillus abscesses, one got pulmonary tuberculosis, and one developed lung cancer. Conclusion Close attention is needed, particularly for respiratory system events and infectious diseases, when treating patients with silica-associated SLE using immunosuppressive therapies.

en-abstract= kn-abstract=Sinonasal inverted papilloma (SNIP) can recur; however, the factors related to tumor recurrence remain unclear. This study aimed to analyze risk factors, including human papillomavirus (HPV) infection, as well as other factors associated with SNIP recurrence. Thirty-two patients who were diagnosed with SNIP and underwent surgery between 2010 and 2019 were enrolled: 24 men and 8 women, with a mean age of 59.2 years. The mean follow-up was 57.3 months. Demographics and information about history of smoking, diabetes mellitus (DM), hypertension, allergic rhinitis, alcohol consumption, tumor stage, surgical approach, and recurrence were reviewed retrospectively. Specimens were investigated using polymerase chain reaction to detect HPV DNA (high-risk subtypes: 16, 18, 31, 33, 35, 52b, and 58; low-risk subtypes: 6 and 11). Seven patients (21.9%) experienced recurrence. HPV DNA was detected in five (15.6%) patients (high-risk subtypes, n = 2; low-risk subtypes, n = 3). Patients with recurrence of SNIP had a higher proportion of young adults and displayed higher rates of HPV infection, DM, and advanced tumor stage than those without recurrence. HPV infection, young adulthood, DM, and advanced tumor stage could be associated with a high recurrence rate, which suggests that patients with these risk factors could require close follow-up after surgery. en-copyright= kn-copyright= en-aut-name=TsumuraMunechika en-aut-sei=Tsumura en-aut-mei=Munechika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MakiharaSeiichiro en-aut-sei=Makihara en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=GionYuka en-aut-sei=Gion en-aut-mei=Yuka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MoritoToshiaki en-aut-sei=Morito en-aut-mei=Toshiaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoShotaro en-aut-sei=Miyamoto en-aut-mei=Shotaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NaitoTomoyuki en-aut-sei=Naito en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=UraguchiKensuke en-aut-sei=Uraguchi en-aut-mei=Kensuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OkaAiko en-aut-sei=Oka en-aut-mei=Aiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=10 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=KariyaShin en-aut-sei=Kariya en-aut-mei=Shin kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OkanoMitsuhiro en-aut-sei=Okano en-aut-mei=Mitsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 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=15 ORCID= affil-num=1 en-affil=Department of Otolaryngology Head and Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=2 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=3 en-affil=Division of Pathophysiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=4 en-affil=Division of Pathophysiology, Graduate School of Health Sciences, Okayama University kn-affil= affil-num=5 en-affil= kn-affil=Department of Pathology, Kagawa Rosai Hospital affil-num=6 en-affil=Department of Otolaryngology Head and Neck Surgery, Kagawa Rosai Hospital kn-affil= affil-num=7 en-affil=Department of Otorhinolaryngology, Kagawa Prefectural Central Hospital kn-affil= affil-num=8 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=9 en-affil=Department of Otorhinolaryngology, School of Medicine, International University of Health and Welfare kn-affil= affil-num=10 en-affil=Department of Otolaryngology, Japanese Red Cross Society Himeji Hospital kn-affil= affil-num=11 en-affil=Department of Otolaryngology Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=12 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=13 en-affil= Department of Otorhinolaryngology, School of Medicine, International University of Health and Welfare kn-affil= affil-num=14 en-affil=Department of Otolaryngology Head and Neck Surgery, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= affil-num=15 en-affil=Department of Pathology, Dentistry and Pharmaceutical Sciences, Graduate School of Medicine, Okayama University kn-affil= en-keyword=HPV infection kn-keyword=HPV infection en-keyword=sinonasal inverted papilloma kn-keyword=sinonasal inverted papilloma en-keyword=diabetes mellitus kn-keyword=diabetes mellitus en-keyword=young adult kn-keyword=young adult en-keyword=tumor stage kn-keyword=tumor stage END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue= article-no= start-page=317 end-page=327 dt-received= dt-revised= dt-accepted= dt-pub-year=2022 dt-pub=20220330 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The Specific Practice of School Based Curriculum Development -

This study explored the risk factors associated with the development of HRS during follow-up. Methods We performed a retrospective analysis of 283 patients with BD-IPMN, treated at Okayama University Hospital in Japan between January 2009 and December 2016. Only patients with imaging studies indicative of classical features of BD-IPMN without HRS and followed for over one year were included in the study. We performed radiological follow-up every six months and collected patients' demographic data, cyst characteristics, and clinical outcomes and used univariate logistic regression models to determine the odds of developing HRS. Results Ten patients (3.5%) developed HRS after a median surveillance period of 55.8 months. The main pancreatic duct (MPD) size (5-9 mm) and cyst growth rate (>2.5 mm/year) were both suggested to be possible risk factors for the development of HRS [odds ratio, 14.2; 95% confidence interval (CI), 3.1-65.2, p=0.0006, and odds ratio, 6.1; 95% CI 1.5-25.5, p=0.014]. Regarding the number of worrisome features (WFs), the rate of HRS development was 2.0% (4/199) in cases with no WF, 1.6% (1/62) in cases with single WF and 22.7% (5/22) in cases with multiple WFs, respectively. The rate of HRS development was significantly higher in cases with multiple WFs than in the other cases (p<0.0001). Conclusion MPD dilation, rapid cyst growth, and multiple WFs were significant risk factors for the development of HRS. In the presence of such features, it is necessary to closely follow the development of HRS and avoid missing the best opportunity to perform surgical intervention. en-copyright= kn-copyright= en-aut-name=YamazakiTatsuhiro en-aut-sei=Yamazaki en-aut-mei=Tatsuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TomodaTakeshi en-aut-sei=Tomoda en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro 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=SaragaiYosuke en-aut-sei=Saragai en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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=10 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=11 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=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 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital 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= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=surveillance kn-keyword=surveillance en-keyword=prognosis factor kn-keyword=prognosis factor en-keyword=intraductal papillary mucinous neoplasm kn-keyword=intraductal papillary mucinous neoplasm en-keyword=pancreatic cancer kn-keyword=pancreatic cancer END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=735 end-page=739 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Multiple Hepatolithiasis Following Hepaticojejunostomy Successfully Treated with Left Hemihepatectomy and Double Hepaticojejunostomy Reconstruction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Surgical intervention for hepatolithiasis following hepaticojejunostomy (HJ) has rarely been reported.

A 72-year-old woman who had undergone HJ for iatrogenic bile duct injury developed repeated cholangitis due to complicated hepatolithiasis accompanied by an atrophied left hepatic lobe and HJ stricture. Since endoscopic intervention was unsuccessful, the patient underwent left hemihepatectomy with HJ re-anastomoses of the common hepatic duct and left hepatic duct (double HJ technique). The double HJ technique with hepatectomy can be a useful option for treating complicated hepatolithiasis following HJ. en-copyright= kn-copyright= en-aut-name=NagaiYasuo en-aut-sei=Nagai en-aut-mei=Yasuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=KuiseTakashi en-aut-sei=Kuise en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=UmedaYuzo en-aut-sei=Umeda en-aut-mei=Yuzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaRyuichi en-aut-sei=Yoshida en-aut-mei=Ryuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YoshidaKazuhiro en-aut-sei=Yoshida en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YasuiKazuya en-aut-sei=Yasui en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YagiTakahito en-aut-sei=Yagi en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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 Gastroenterological Surgery, 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 Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Gastroenterological Surgery, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=hepatolithiasis kn-keyword=hepatolithiasis en-keyword=hepaticojejunostomy kn-keyword=hepaticojejunostomy en-keyword=hepatectomy kn-keyword=hepatectomy END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=6 article-no= start-page=699 end-page=704 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202112 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Guideline-based Treatment of Glucocorticoid-induced Osteoporosis in Patients with Rheumatoid Arthritis: A Retrospective Study with the AORA Registry en-subtitle= kn-subtitle= en-abstract= kn-abstract=Glucocorticoid-induced osteoporosis (GIOP) is one of the side effects associated with glucocorticoid (GC) therapy. In 2014, the Japanese Society for Bone and Mineral Research (JSBMR) provided new guidelines for the management and treatment of GIOP. The aim of the present study was to clarify the prevalence of patients with rheumatoid arthritis (RA) requiring treatment according to the new guidelines and to identify risk factors associated with lack of treatment in these patients. Patients in the 2018 Akita Orthopedic group on Rheumatoid Arthritis (AORA) database were enrolled. Of 2,234 patients with RA in the database, 683 (30.6%) met the 2014 JSBMR guideline treatment criteria, and 480 (70.3%) had been treated. The untreated group included a larger number of males, younger patients, and patients treated in clinics rather than hospital (p<0.001, p=0.015, and p<0.001, respectively). Multivariate analyses found that male sex, younger age, and clinic-based RA care were significant risk factors associated with lack of treatment (p<0.001, p=0.013, and p<0.001, respectively). Thus, male sex, younger age, and clinic-based care were identified as risk factors en-copyright= kn-copyright= en-aut-name=KawanoTetsuya en-aut-sei=Kawano en-aut-mei=Tetsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 ORCID= en-aut-name=TsuchieHiroyuki en-aut-sei=Tsuchie en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KashiwaguraTakeshi en-aut-sei=Kashiwagura en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KobayashiMoto en-aut-sei=Kobayashi en-aut-mei=Moto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=AonumaHiroshi en-aut-sei=Aonuma en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SugimuraYusuke en-aut-sei=Sugimura en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShimadaYoichi en-aut-sei=Shimada en-aut-mei=Yoichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine 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, Akita University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Orthopedic Surgery, Akita City Hospital kn-affil= affil-num=5 en-affil=Department of Orthopedic Surgery, Hiraka General Hospital Yokote City kn-affil= affil-num=6 en-affil=Department of Orthopedic Surgery, Ogachi Central Hospital Yuzawa City kn-affil= affil-num=7 en-affil=Department of Orthopedic Surgery, Nakadori General Hospital Akita City kn-affil= affil-num=8 en-affil=Department of Orthopedic Surgery, Akita University Graduate School of Medicine kn-affil= en-keyword=glucocorticoid kn-keyword=glucocorticoid en-keyword=glucocorticoid-induced osteoporosis kn-keyword=glucocorticoid-induced osteoporosis en-keyword=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=osteoporosis kn-keyword=osteoporosis en-keyword=osteopenia kn-keyword=osteopenia END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page=1 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210810 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Who is at high-risk in J wave syndromes? en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Brugada syndrome kn-keyword=Brugada syndrome en-keyword=Early repolarization syndrome kn-keyword=Early repolarization syndrome en-keyword=J wave syndrome kn-keyword=J wave syndrome END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=495 end-page=503 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effects of Tablet Size and Head Posture on Drug Swallowing: A Preliminary Examination Using Endoscopy in Healthy Subjects en-subtitle= kn-subtitle= en-abstract= kn-abstract=Tablet size and head posture have been reported to affect swallowing of medications, but no previous studies have evaluated their effects in detail. Our aim was to investigate for the first time the effect of tablet size and head posture on drug swallowing by endoscopic evaluation in healthy subjects. Round tablets (7 , 10 , 12, and 14 mm in diameter) were swallowed by 15 healthy adults with an endoscope inserted in the neutral, head flex-ion, and head extension positions. Evaluation of swallowing difficulty using a numeric rating scale (NRS), presence or absence of pharyngeal residue and its location, and tablet oral transit time (TOTT) were recorded. In the neutral position, the NRS score was higher with the 14 mm tablets than with the 7 mm tablets. The TOTT with the 7 mm tablets was significantly shorter in the head extension than in the neutral position. Swallowing difficulty increased when the tablet diameter was more than 7 mm. Residues were found in the epi-glottis, pyriform sinus, and tongue base. These findings suggest that head extension shortens the TOTT and assists oral-pharyngeal transport. en-copyright= kn-copyright= en-aut-name=SugiyamaShuntaro en-aut-sei=Sugiyama en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IidaTakatoshi en-aut-sei=Iida en-aut-mei=Takatoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MorimotoYoshinari en-aut-sei=Morimoto en-aut-mei=Yoshinari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=YamazakiYuki en-aut-sei=Yamazaki en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MikuzukiLou en-aut-sei=Mikuzuki en-aut-mei=Lou kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HayashiMegumi en-aut-sei=Hayashi en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Division of Medically Compromised Geriatric Dentistry, Department of Critical Care Medicine and Dentistry, Kanagawa Dental University Hospital Graduate School of Dentistry kn-affil= affil-num=2 en-affil=Division of Medically Compromised Geriatric Dentistry, Department of Critical Care Medicine and Dentistry, Kanagawa Dental University Hospital Graduate School of Dentistry kn-affil= affil-num=3 en-affil=Division of Medically Compromised Geriatric Dentistry, Department of Critical Care Medicine and Dentistry, Kanagawa Dental University Hospital Graduate School of Dentistry kn-affil= affil-num=4 en-affil=Division of Medically Compromised Geriatric Dentistry, Department of Pharmacy, Kanagawa Dental University Hospital kn-affil= affil-num=5 en-affil=Division of Medically Compromised Geriatric Dentistry, Department of Critical Care Medicine and Dentistry, Kanagawa Dental University Hospital Graduate School of Dentistry kn-affil= affil-num=6 en-affil=Division of Medically Compromised Geriatric Dentistry, Department of Critical Care Medicine and Dentistry, Kanagawa Dental University Hospital Graduate School of Dentistry kn-affil= en-keyword=tablet size kn-keyword=tablet size en-keyword=head posture kn-keyword=head posture en-keyword=swallowing kn-keyword=swallowing en-keyword=endoscopy kn-keyword=endoscopy en-keyword=pharyngeal residue kn-keyword=pharyngeal residue END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=471 end-page=477 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Two Types of Polyp Shape Observed in the Stomach of Patients with Peutz-Jeghers Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=The characteristics of gastric polyps in patients with Peutz-Jeghers (PJ) syndrome (PJS) have not been fully investigated. The objective of this study was to reveal the endoscopic and pathologic findings of gastric polyps in patients with PJS. We reviewed 11 patients with PJS treated at 6 institutions, and summarized the endo-scopic and pathologic features of their gastric polyps. The polyps were mainly classified into 2 types: (i) soli-tary or sporadic polyps > 5 mm, reddish in color with a sessile or semi-pedunculated morphology (n = 9); and (ii) multiple sessile polyps ≤ 5 mm with the same color tone as the peripheral mucosa (n = 9). Patients who underwent endoscopic mucosal resection for polyps > 5 mm were diagnosed with PJ polyps (n = 2), whereas those who underwent biopsy were diagnosed with hyperplastic polyps. Polyps ≤ 5 mm were pathologically diagnosed as fundic gland polyps or hyperplastic polyps. This study revealed that patients with PJS present with 2 types of polyps in the stomach. Endoscopic mucosal resection of polyps > 5 mm seems necessary for the pathologic diagnosis of PJ polyps. 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=ToyokawaTatsuya en-aut-sei=Toyokawa en-aut-mei=Tatsuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=HoriShinichiro en-aut-sei=Hori en-aut-mei=Shinichiro 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=MoritouYuki en-aut-sei=Moritou en-aut-mei=Yuki 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=MizunoMotowo en-aut-sei=Mizuno en-aut-mei=Motowo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 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, Fukuyama Medical Center kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=4 en-affil=Department of Endoscopy, Shikoku Cancer Center kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Okayama Saiseikai General 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 Pathology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Peutz-Jeghers syndrome kn-keyword=Peutz-Jeghers syndrome en-keyword= esophagogastroduodenoscopy kn-keyword= esophagogastroduodenoscopy en-keyword=gastric polyps kn-keyword=gastric polyps END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=461 end-page=469 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Bendamustine Plus Rituximab as Salvage Treatment for Patients with Relapsed or Refractory Low-grade B-cell Lymphoma and Mantle Cell Lymphoma: A Single-Center Retrospective Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Bendamustine plus rituximab (B-R) is an effective therapy for relapsed or refractory (r/r) low-grade B-cell lymphoma (LGBCL) and mantle cell lymphoma (MCL); however, clinical data from Japanese patients treated with B-R therapy are limited. We retrospectively evaluated the efficacy and safety of B-R therapy in 42 patients who received B-R therapy at our hospital for r/r LGBCL and MCL. All patients received intravenous (IV) ritux-imab 375 mg/m2 on day 1 and IV bendamustine 90 mg/m2 on days 2 and 3 every 28 days for up to 6 cycles. The common histologic subtypes were follicular lymphoma (n = 29, 70%), marginal zone lymphoma (n = 6, 14%), and MCL (n = 5, 12%). The overall response rate was 93%, with 62% complete response and complete response unconfirmed. The median progression-free survival (PFS) was 38 months (95% confidence interval [CI], 24.6 to not reached [NR]), and the median overall survival (OS) was 80 months (95% CI, 60.7 to NR). Patients receiving a cumulative dose of bendamustine ≥ 720 mg/m2 showed a significantly longer PFS and OS. Grade 3/4 adverse events (≥ 10%) included neutropenia (55%), lymphopenia (69%), and nausea (24%). B-R therapy was effective and well tolerated, and the cumulative dose of bendamustine was associated with a favorable outcome. en-copyright= kn-copyright= en-aut-name=MurakamiHiroyuki en-aut-sei=Murakami en-aut-mei=Hiroyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YoshiokaTakanori en-aut-sei=Yoshioka en-aut-mei=Takanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyamaTakashi en-aut-sei=Moriyama en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=IshikawaTatsunori en-aut-sei=Ishikawa en-aut-mei=Tatsunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MakitaMasanori en-aut-sei=Makita en-aut-mei=Masanori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SunamiKazutaka en-aut-sei=Sunami en-aut-mei=Kazutaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=2 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=3 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=4 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=5 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= affil-num=6 en-affil=Department of Hematology, National Hospital Organization Okayama Medical Center kn-affil= en-keyword=bendamustine kn-keyword=bendamustine en-keyword=low grade B-cell lymphoma kn-keyword=low grade B-cell lymphoma en-keyword=mantle cell lymphoma kn-keyword=mantle cell lymphoma END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=4 article-no= start-page=403 end-page=413 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202108 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Surgical Treatment of Epiretinal Membrane en-subtitle= kn-subtitle= en-abstract= kn-abstract=Epiretinal membrane (ERM) is a common retinal disease characterized by cellular proliferation and metaplasia that lead to the formation of a pathological fibrocellular membrane immediately superjacent to the inner retinal surface. The vast majority of ERMs are considered idiopathic. However, ERM formation can result from various primary intraocular diseases, including retinal breaks and detachment, retinal vascular diseases, and vitreoretinal inflammatory conditions. Although ERMs are generally asymptomatic or cause mild metamorphopsia and/or a modest decrease in visual acuity, some can cause severe macular distortion and macular edema, resulting in significantly impaired function. Surgical removal of ERM is the only treatment, and improvements in vitrectomy systems have enabled less invasive treatment. However, there are currently no standardized criteria for ERM surgery, and the indications for surgery are determined from the patient’s subjective symptoms. Another problem with ERM surgery is that not all patients show satisfactory postoperative recovery of visual function. Thus, further research is needed to determine the criteria for ERM surgery and methods to improve the postoperative prognosis. en-copyright= kn-copyright= en-aut-name=MatobaRyo en-aut-sei=Matoba en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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= en-keyword=epiretinal membrane kn-keyword=epiretinal membrane en-keyword=vitrectomy kn-keyword=vitrectomy en-keyword=optical coherence tomography kn-keyword=optical coherence tomography en-keyword=internal limiting membrane kn-keyword=internal limiting membrane en-keyword=lamellar macular hole kn-keyword=lamellar macular hole END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=15 article-no= start-page=3314 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210727 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Balloon Enteroscopy-Assisted Endoscopic Retrograde Cholangiopancreatography for the Treatment of Common Bile Duct Stones in Patients with Roux-en-Y Gastrectomy: Outcomes and Factors Affecting Complete Stone Extraction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Endoscopic retrograde cholangiopancreatography (ERCP) for extraction of common bile duct (CBD) stones in patients with Roux-en-Y gastrectomy (RYG) remains technically challenging. Methods: Seventy-nine RYG patients (median 79 years old) underwent short-type double-balloon enteroscopy-assisted ERCP (sDBE-ERCP) for CBD stones at three referral hospitals from 2011-2020. We retrospectively investigated the treatment outcomes and potential factors affecting complete stone extraction.

Results: The initial success rates of reaching the papilla of Vater, biliary cannulation, and biliary intervention, including complete stone extraction or biliary stent placement, were 92%, 81%, and 78%, respectively. Of 57 patients with attempted stone extraction, complete stone extraction was successful in 74% for the first session and ultimately in 88%. The adverse events rate was 5%. The multivariate analysis indicated that the largest CBD diameter >= 14 mm (odds ratio (OR), 0.04; 95% confidence interval (CI), 0.01-0.58; p = 0.018) and retroflex position (OR, 6.43; 95% CI, 1.12-36.81; p = 0.037) were independent predictive factors affecting complete stone extraction achievement.

Conclusions: Therapeutic sDBE-ERCP for CBD stones in a relatively elderly RYG cohort, was effective and safe. A larger CBD diameter negatively affected complete stone extraction, but using the retroflex position may be useful for achieving complete stone clearance. en-copyright= kn-copyright= en-aut-name=ObataTaisuke en-aut-sei=Obata en-aut-mei=Taisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=2 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=3 ORCID= en-aut-name=UekiToru en-aut-sei=Ueki en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 ORCID= en-aut-name=YasugiKengo en-aut-sei=Yasugi en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=OgawaTsuneyoshi en-aut-sei=Ogawa en-aut-mei=Tsuneyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 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=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, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=12 en-affil=Department of Internal Medicine, Fukuyama City Hospital kn-affil= affil-num=13 en-affil=Department of Internal Medicine, Tsuyama Chuo Hospital kn-affil= affil-num=14 en-affil=Department of Gastroenterology, Okayama University Hospital kn-affil= en-keyword=bile duct stone kn-keyword=bile duct stone en-keyword=endoscopic retrograde cholangiography kn-keyword=endoscopic retrograde cholangiography en-keyword=Roux-en-Y anastomosis kn-keyword=Roux-en-Y anastomosis en-keyword=short-type balloon enteroscopy kn-keyword=short-type balloon enteroscopy en-keyword=complete stone removal kn-keyword=complete stone removal en-keyword=gastrectomy kn-keyword=gastrectomy END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=3 article-no= start-page=289 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202106 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy and Safety of Early Intravenous Landiolol on Myocardial Salvage in Patients with ST-segment Elevation Myocardial Infarction before Primary Percutaneous Coronary Intervention: A Randomized Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Early treatment with an oral β-blocker is recommended in patients with a ST-segment–elevation myocardial infarction (STEMI). In this multicenter study, we evaluated the effects of a continuous administration of landiolol, an ultrashort-acting β-blocker, before primary percutaneous coronary intervention (PCI) on myocardial salvage and its safety in STEMI patients. A total of 47 Japanese patients with anterior or lateral STEMI undergoing a primary PCI within 12 h of symptom onset were randomized to receive intravenous landiolol (started at 3 μg/min/kg dose and continued to a total of 50 mg; n=23) or not (control; n=24). Patients with Killip class III or more were excluded. The primary outcome was the myocardial salvage index on cardiac magnetic resonance imaging (MRI) performed 5-7 days after the PCI. Cardiac MRI was performed in 35 patients (74%). The myocardial salvage index in the landiolol group was significantly greater than that in the control group (44.4±14.6% vs. 31.7±18.9%, respectively; p=0.04). There were no significant differences in adverse events at 24 h between the landiolol and control groups. A continuous administration of landiolol before a primary PCI may increase the degree of myocardial salvage without additional hemodynamic adverse effects within the first 24 h after STEMI. en-copyright= kn-copyright= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OsawaKazuhiro en-aut-sei=Osawa en-aut-mei=Kazuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyoshiToru en-aut-sei=Miyoshi en-aut-mei=Toru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MoriAtsushi en-aut-sei=Mori en-aut-mei=Atsushi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshikawaMasaki en-aut-sei=Yoshikawa en-aut-mei=Masaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkaTakefumi en-aut-sei=Oka en-aut-mei=Takefumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IchikawaKeishi en-aut-sei=Ichikawa en-aut-mei=Keishi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiology, Tsuyama Central Hospital kn-affil= affil-num=5 en-affil=Department of Cardiology, Fukuyama City Hospital kn-affil= affil-num=6 en-affil=Department of Cardiology, Tsuyama Central Hospital kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=myocardial infarction kn-keyword=myocardial infarction en-keyword=landiolol kn-keyword=landiolol en-keyword= magnetic resonance imaging kn-keyword= magnetic resonance imaging en-keyword=STEMI kn-keyword=STEMI en-keyword=PCI kn-keyword=PCI END start-ver=1.4 cd-journal=joma no-vol=8 cd-vols= no-issue= article-no= start-page=668059 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210524 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Novel Urinary Glycan Biomarkers Predict Cardiovascular Events in Patients With Type 2 Diabetes: A Multicenter Prospective Study With 5-Year Follow Up (U-CARE Study 2) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background: Although various biomarkers predict cardiovascular event (CVE) in patients with diabetes, the relationship of urinary glycan profile with CVE in patients with diabetes remains unclear. Methods: Among 680 patients with type 2 diabetes, we examined the baseline urinary glycan signals binding to 45 lectins with different specificities. Primary outcome was defined as CVE including cardiovascular disease, stroke, and peripheral arterial disease. Results: During approximately a 5-year follow-up period, 62 patients reached the endpoint. Cox proportional hazards analysis revealed that urinary glycan signals binding to two lectins were significantly associated with the outcome after adjustment for known indicators of CVE and for false discovery rate, as well as increased model fitness. Hazard ratios for these lectins (+1 SD for the glycan index) were UDA (recognizing glycan: mixture of Man5 to Man9): 1.78 (95% CI: 1.24-2.55, P = 0.002) and Calsepa [High-Man (Man2-6)]: 1.56 (1.19-2.04, P = 0.001). Common glycan binding to these lectins was high-mannose type of N-glycans. Moreover, adding glycan index for UDA to a model including known confounders improved the outcome prediction [Difference of Harrel's C-index: 0.028 (95% CI: 0.001-0.055, P = 0.044), net reclassification improvement at 5-year risk increased by 0.368 (0.045-0.692, P = 0.026), and the Akaike information criterion and Bayesian information criterion decreased from 725.7 to 716.5, and 761.8 to 757.2, respectively]. Conclusion: The urinary excretion of high-mannose glycan may be a valuable biomarker for improving prediction of CVE in patients with type 2 diabetes, and provides the rationale to explore the mechanism underlying abnormal N-glycosylation occurring in patients with diabetes at higher risk of CVE. en-copyright= kn-copyright= en-aut-name=MiseKoki en-aut-sei=Mise en-aut-mei=Koki kn-aut-name=

ventricular tachycardia in a patient with double outlet right ventricle who underwent Fontan operation: a case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
The incidence of ventricular tachycardia (VT) in patients following Fontan operation is reported as 3.5%. Furthermore, in patients with repaired double outlet right ventricle (DORV), scar-related VT and outflow tract VT have been reported; however, Purkinje-related VT has not previously been reported. In this report, we present the case of idiopathic left VT (ILVT) in a patient with DORV who underwent Fontan operation.

Case summary
A 31-year-old man was diagnosed as having DORV with complete atrioventricular defect at birth. When he was 17 years old, he underwent surgical repair, including extracardiac Fontan operation and common atrioventricular valve replacement. Five years later, VT was detected. Since some medications were ineffective in suppressing VT, he was referred to our hospital for definitive treatment. Ventricular tachycardia was induced by atrial and ventricular programmed electrical stimulations. The mechanism of the VT was determined to be re-entry. The earliest activation site was located at the mid-inferior septum of the hypoplastic left ventricle, in which Purkinje potentials were observed before the local ventricular electrogram. Radiofrequency catheter ablation (RFCA) was performed at this site to eliminate VT.

Discussion
Most VTs originate from surgical scars in patients with congenital heart disease. Catheter ablation was feasible in scar-related VT. To the best of our knowledge, this is the first report of ILVT treated successfully with RFCA in a DORV patient who had undergone Fontan operation. en-copyright= kn-copyright= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito 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 Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= en-keyword=Idiopathic left ventricular tachycardia kn-keyword=Idiopathic left ventricular tachycardia en-keyword=Double outlet right ventricle kn-keyword=Double outlet right ventricle en-keyword=Fontan operation kn-keyword=Fontan operation en-keyword=Purkinje potential kn-keyword=Purkinje potential en-keyword=Case report kn-keyword=Case report END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=249 end-page=253 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Endogenous Bacterial Endophthalmitis Caused by Iliopsoas Abscess en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 79-year-old woman presented to our hospital with a 10-day history of gradually worsening binocular vision and severe backache. Further investigations revealed poor bilateral best-corrected visual acuities (BCVA), bilateral vitreous opacities, gray-white lesions scattered throughout the retina, and a left iliopsoas abscess on CT that later grew out methicillin-sensitive S. aureus. The abscess was drained and intravenous antibiotics were initiated, but the left eye additionally required intravitreal vancomycin. BCVA for both eyes normalized within 1 year. Intramuscular abscess should be considered as a possible primary lesion in cases of endogenous bacterial endophthalmitis. en-copyright= kn-copyright= en-aut-name=SunWeiying en-aut-sei=Sun en-aut-mei=Weiying 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=TokumasuKazuki en-aut-sei=Tokumasu en-aut-mei=Kazuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 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=5 ORCID= en-aut-name=DoiShinichiro en-aut-sei=Doi en-aut-mei=Shinichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=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=MorizaneYuki en-aut-sei=Morizane en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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 General Medicine, 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=Department of General Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Ophthalmology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=endogenous bacterial endophthalmitis kn-keyword=endogenous bacterial endophthalmitis en-keyword=methicillin-sensitive Staphylococcus aureus kn-keyword=methicillin-sensitive Staphylococcus aureus en-keyword=iliopsoas abscess kn-keyword=iliopsoas abscess en-keyword=intravitreal injection kn-keyword=intravitreal injection en-keyword=vancomycin kn-keyword=vancomycin END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=2 article-no= start-page=243 end-page=248 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202104 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pyogenic Ventriculitis After Anterior Skull Base Surgery Treated With Endoscopic Ventricular Irrigation And Reconstruction Using a Vascularized Flap en-subtitle= kn-subtitle= en-abstract= kn-abstract=Ventriculitis is a rare, serious complication of neurosurgery. A 59-year-old man who had undergone a craniotomy for a paranasal adenocarcinoma, developed a right frontal cystic lesion. We performed a bifrontal craniotomy to remove the lesion.

Ventricular drainage, craniectomy, and endoscopic irrigation were undertaken to remove an abscess. The dura and the resection cavity were reconstructed using a vascularized anterolateral thigh adipofascial flap. His symptoms disappeared, indicating that endoscopic irrigation and reconstruction can effectively address ventriculitis even in patients in critical clinical condition. 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=ShimazuYosuke en-aut-sei=Shimazu en-aut-mei=Yosuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KawakamiMasato en-aut-sei=Kawakami en-aut-mei=Masato kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumotoHiroshi en-aut-sei=Matsumoto en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 ORCID= en-aut-name=KamedaMasahiro en-aut-sei=Kameda en-aut-mei=Masahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 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=8 ORCID= en-aut-name=OtaTomoyuki en-aut-sei=Ota en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KimataYoshihiro en-aut-sei=Kimata en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko 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=Plastic and Reconstructive 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 Plastic and Reconstructive Surgery, Okayama University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Plastic and Reconstructive 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= en-keyword=ventriculitis kn-keyword=ventriculitis en-keyword=surgical site infection kn-keyword=surgical site infection en-keyword=intraventricular antimicrobial therapy kn-keyword=intraventricular antimicrobial therapy en-keyword=anterior skull base surgery kn-keyword=anterior skull base surgery END start-ver=1.4 cd-journal=joma no-vol=16 cd-vols= no-issue=3 article-no= start-page=e0245502 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=20210304 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Usefulness of right ventriculography compared with computed tomography for ruling out the possibility of lead perforation before lead extraction en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose High-risk patients can be identified by preprocedural computed tomography (CT) before lead extraction. However, CT evaluation may be difficult especially for lead tip identification due to artifacts in the leads. Selective right ventriculography (RVG) may enable preprocedural evaluation of lead perforation. We investigated the efficacy of RVG for identifying right ventricular (RV) lead perforation compared with CT in patients who underwent lead extraction. Methods Ninety-five consecutive patients who were examined by thin-section non-ECG-gated multi-detector CT and RVG before lead extraction were investigated retrospectively. Newly recognized pericardial effusion after lead extraction was used as a reference standard for lead perforation. We analyzed the prevalence of RV lead perforation diagnosed by each method. The difference in the detection rates of lead perforation by RVG and CT was evaluated. Results Of the 115 RV leads in the 95 patients, lead perforation was diagnosed for 35 leads using CT, but the leads for 29 (83%) of those 35 leads diagnosed as lead perforation by CT were shown to be within the right ventricle by RVG. Three patients with 5 leads could not be evaluated by CT due to motion artifacts. The diagnostic accuracies of RVG and CT were significantly different (p < 0.001). There was no complication of pericardial effusion caused by RV lead extraction. Conclusion RVG for identification of RV lead perforation leads to fewer false-positives compared to non-ECG-gated CT. However, even in cases in which lead perforation is diagnosed, most leads may be safely extracted by transvenous lead extraction. en-copyright= kn-copyright= en-aut-name=AsadaSaori en-aut-sei=Asada en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShinyaTakayoshi en-aut-sei=Shinya en-aut-mei=Takayoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiAkihito en-aut-sei=Miyoshi en-aut-mei=Akihito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MorimotoYoshimasa en-aut-sei=Morimoto en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=NakamuraKazufumi en-aut-sei=Nakamura en-aut-mei=Kazufumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=3 en-affil=Department of Pediatric Radiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=9 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= END start-ver=1.4 cd-journal=joma no-vol=75 cd-vols= no-issue=1 article-no= start-page=31 end-page=37 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment Outcomes of Pulmonary Metastases from Head and Neck Squamous Cell Carcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Although the lung is the most common site of distant metastases from head and neck squamous cell carcinoma (HNSCC), the number of reports about the effects of pulmonary metastasectomy for the treatment of lung metastasis from HNSCC is limited. Metachronous pulmonary metastases were detected in 45 HNSCC patients at Kumamoto University Hospital from 1998 to 2018. Twenty-two patients underwent an operative resection (Ope group) and 23 underwent chemotherapy (Chemo group). The 3-year overall survival (OS) rate and median OS were evaluated. The effects of adjuvant chemotherapy after pulmonary metastasectomy and of new drugs (cetuximab and nivolumab), in the chemo group were also assessed. The 3-year OS rates and median OS were: Ope, 66.1% and 31.5 months; Chemo, 39.7% and 18 months, respectively. In the Ope group, addi-tional recurrences were significantly fewer in the patients who underwent adjuvant chemotherapy post-surgery versus the patients who underwent surgery alone (p = 0.013). In the Chemo group, the 3-year OS rate of the patients who received new drugs was significantly better than that of the patients who did not (p = 0.021). Adjuvant chemotherapy after pulmonary metastasectomy may be a preferable treatment option for preventing recurrences. Cetuximab and nivolumab have a potential to improve OS. en-copyright= kn-copyright= en-aut-name=MiyamaruSatoru en-aut-sei=Miyamaru en-aut-mei=Satoru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MurakamiDaizo en-aut-sei=Murakami en-aut-mei=Daizo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NishimotoKohei en-aut-sei=Nishimoto en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SaitoHaruki en-aut-sei=Saito en-aut-mei=Haruki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoYusuke en-aut-sei=Miyamoto en-aut-mei=Yusuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HirotaKaoruko en-aut-sei=Hirota en-aut-mei=Kaoruko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IseMomoko en-aut-sei=Ise en-aut-mei=Momoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OritaYorihisa en-aut-sei=Orita en-aut-mei=Yorihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=2 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=3 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=4 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=5 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=6 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=7 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= affil-num=8 en-affil=Department of Otolaryngology-Head and Neck Surgery, Graduate School of Medicine, Kumamoto University kn-affil= en-keyword=pulmonary metastasis kn-keyword=pulmonary metastasis en-keyword=head and neck squamous cell carcinoma kn-keyword=head and neck squamous cell carcinoma en-keyword=pulmonary metastasectomy kn-keyword=pulmonary metastasectomy en-keyword=adjuvant chemotherapy kn-keyword=adjuvant chemotherapy END start-ver=1.4 cd-journal=joma no-vol=28 cd-vols= no-issue=1 article-no= start-page=111 end-page=119 dt-received= dt-revised= dt-accepted= dt-pub-year=2021 dt-pub=202101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Absolute X-ray energy measurement using a high-accuracy angle encoder en-subtitle= kn-subtitle= en-abstract= kn-abstract=This paper presents an absolute X-ray photon energy measurement method that uses a Bond diffractometer. The proposed system enables the prompt and rapid in situ measurement of photon energies over a wide energy range. The diffractometer uses a reference silicon single-crystal plate and a highly accurate angle encoder called SelfA. The performance of the system is evaluated by repeatedly measuring the energy of the first excited state of the potassium-40 nuclide. The excitation energy is determined as 29829.39 (6) eV, and this is one order of magnitude more accurate than the previous measurement. The estimated uncertainty of the photon energy measurement was 0.7 p.p.m. as a standard deviation and the maximum observed deviation was 2 p.p.m. en-copyright= kn-copyright= en-aut-name=MasudaTakahiko

To clarify the prevalence of albuminuria and renal dysfunction, and related factors in Japanese patients with diabetes, we analyzed the baseline data of the Japan Diabetes Complication and its Prevention prospective study.
Materials and Methods
We used the data of 355 patients with type 1 diabetes and 5,194 patients with type 2 diabetes to evaluate the prevalence of albuminuria and renal dysfunction, and related factors. A binomial logistic regression analysis was used to investigate independent contributing factors for estimated glomerular filtration rate <60 mL/min/1.73 m2 or albuminuria.
Results
The prevalence of microalbuminuria and macroalbuminuria was 15.2% (54/355) and 3.1% (11/355) in type 1 diabetes patients, and 25.0% (1,298/5,194) and 5.1% (265/5,194) in type 2 diabetes patients, respectively. The proportion of renal dysfunction (estimated glomerular filtration rate <60 mL/min/1.73 m2) was 9.9% (35/355) in type 1 diabetes patients, and 15.3% (797/5,194) in type 2 diabetes patients. The proportion of patients with renal dysfunction with normoalbuminuria was 7.3% (26/355) for type 1 diabetes patients, and 9.0% (467/5,194) for type 2 diabetes patients. The factors related to albuminuria in type 2 diabetes patients were glycated hemoglobin, hypertension, age, duration of diabetes, body mass index and estimated glomerular filtration rate. In contrast, factors to related renal dysfunction were age, duration of diabetes, dyslipidemia, hypertension, body mass index, male sex and albuminuria.
Conclusions
We showed the recent prevalence of albuminuria and renal dysfunction, and related factors in Japanese type 1 and type 2 diabetes patients using the baseline data of the Japan Diabetes Complication and its Prevention prospective study. The current results suggest that renal disease in patients with type 2 diabetes is heterogeneous, and different mechanisms might be involved in albuminuria and deterioration of renal function. en-copyright= kn-copyright= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KoderaRyo en-aut-sei=Kodera en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=UtsunomiyaKazunori en-aut-sei=Utsunomiya en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoyaDaisuke en-aut-sei=Koya en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraRimei en-aut-sei=Nishimura en-aut-mei=Rimei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=TajimaNaoko en-aut-sei=Tajima en-aut-mei=Naoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=the JDCP study group en-aut-sei=the JDCP study group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=The Japan Diabetes Society kn-affil= affil-num=3 en-affil=The Japan Diabetes Society kn-affil= affil-num=4 en-affil=The Japan Diabetes Society kn-affil= affil-num=5 en-affil=The Japan Diabetes Society kn-affil= affil-num=6 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=7 en-affil=The Japan Diabetes Society kn-affil= affil-num=8 en-affil= kn-affil= en-keyword=Diabetic nephropathy kn-keyword=Diabetic nephropathy en-keyword=Diabetic kidney disease kn-keyword=Diabetic kidney disease en-keyword=Japan Diabetes Complication and its Prevention study kn-keyword=Japan Diabetes Complication and its Prevention study END start-ver=1.4 cd-journal=joma no-vol=9 cd-vols= no-issue=23 article-no= start-page=e016907 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201123 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Significance of Exercise-Related Ventricular Arrhythmias in Patients With Brugada Syndrome en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Sinus tachycardia during exercise attenuates ST‐segment elevation in patients with Brugada syndrome, whereas ST‐segment augmentation after an exercise test is a high‐risk sign. Some patients have premature ventricular contractions (PVCs) related to exercise, but the significance of exercise‐related PVCs in patients with Brugada syndrome is still unknown. The objective of this study was to determine the significance of exercise‐related PVCs for predicting occurrence of ventricular fibrillation (VF) in patients with Brugada syndrome.
Methods and Results
The subjects were 307 patients with Brugada syndrome who performed a treadmill exercise test. We evaluated the occurrence of PVCs at rest, during exercise and at the peak of exercise, and during recovery after exercise (0–5 minutes). We followed the patients for 92±68 months and evaluated the occurrence of VF. PVCs occurred in 82 patients (27%) at the time of treadmill exercise test: PVCs appeared at rest in 14 patients (4%), during exercise in 60 patients (20%), immediately after exercise (0–1.5 minutes) in 28 patients (9%), early after exercise (1.5–3 minutes) in 18 patients (6%), and late after exercise (3–5 minutes) in 12 patients (4%). Thirty patients experienced VF during follow‐up. Multivariable analysis including symptoms, spontaneous type 1 ECG, and PVCs in the early recovery phase showed that these factors were independently associated with VF events during follow‐up.
Conclusions
PVCs early after an exercise test are associated with future occurrence of VF events. Rebound of vagal nerve activity at the early recovery phase would promote ST‐segment augmentation and PVCs in high‐risk patients with Brugada syndrome. en-copyright= kn-copyright= en-aut-name=MoritaHiroshi en-aut-sei=Morita en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=AsadaSaori T. en-aut-sei=Asada en-aut-mei=Saori T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyamotoMasakazu en-aut-sei=Miyamoto en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MorimotoYoshimasa en-aut-sei=Morimoto en-aut-mei=Yoshimasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KimuraTomonari en-aut-sei=Kimura en-aut-mei=Tomonari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MizunoTomofumi en-aut-sei=Mizuno en-aut-mei=Tomofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=NakagawaKoji en-aut-sei=Nakagawa en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=WatanabeAtsuyuki en-aut-sei=Watanabe en-aut-mei=Atsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=NishiiNobuhiro en-aut-sei=Nishii en-aut-mei=Nobuhiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=ItoHiroshi en-aut-sei=Ito en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=3 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=4 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=5 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=6 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=7 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=8 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= affil-num=9 en-affil=Department of Cardiovascular Therapeutics, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Cardiovascular Medicine, Okayama University Graduate School of Medicine and Dentistry kn-affil= en-keyword=Brugada syndrome kn-keyword=Brugada syndrome en-keyword=exercise test kn-keyword=exercise test en-keyword=premature ventricular contractions kn-keyword=premature ventricular contractions en-keyword=sudden death kn-keyword=sudden death en-keyword=ventricular fibrillation kn-keyword=ventricular fibrillation END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=557 end-page=562 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Japanese Patient with Gastric Cancer and Dihydropyrimidine Dehydrogenase Deficiency Presenting with DPYD Variants en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 63-year-old Japanese male with stomach adenocarcinoma received oral 5-fluorouracil derivative, cisplatin and trastuzumab chemotherapy.

The AI comprised of neural network architecture was trained by deep learning with a dataset that consists of ± 2 standard devia-tion (SD), ± 1.5SD, and ± 0SD categories of the approved standard values of ultrasonic measurements of the fetal weights of Japanese fetuses (Japan Society of Ultrasonics in Medicine [JSUM] data). We investigated the residuals and compared 2 other regression formulae for estimating the fetal weights of Japanese fetuses by t-test and Bland-Altman analyses, respectively. The residuals of the AI for the test dataset that was 12.5% of the JSUM data were 6.4 ± 2.6, −3.8 ± 8.6, and −0.32 ± 6.3 (g) at −2SD, +2SD, and all categories, respectively. The residu-als of another AI method created with all of the JSUM data, of which 20% were randomized validation data, were −1.5 ± 9.4, −2.5 ± 7.3, and −1.1 ± 6.7 (g) for −2SD, +2SD, and all categories, respectively. The residuals of this AI were not different from zero, whereas those of the published formulae differed from zero. Though vali-dation is required, the AI demonstrated potential for generating fetal weights accurately, especially for extreme fetal weights. en-copyright= kn-copyright= en-aut-name=MiyagiYasunari en-aut-sei=Miyagi en-aut-mei=Yasunari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyakeTakahito en-aut-sei=Miyake en-aut-mei=Takahito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=Medical Data Labo kn-affil= affil-num=2 en-affil=Department of Obstetrics and Gynecology, Miyake Clinic kn-affil= en-keyword=deep learning kn-keyword=deep learning en-keyword=artificial intelligence kn-keyword=artificial intelligence en-keyword=fetal weight kn-keyword=fetal weight en-keyword=neural network kn-keyword=neural network en-keyword=ultrasound biometry kn-keyword=ultrasound biometry END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=6 article-no= start-page=461 end-page=466 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202012 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Reality of Gastric Cancer in Young Patients: The Importance and Difficulty of the Early Diagnosis, Prevention and Treatment en-subtitle= kn-subtitle= en-abstract= kn-abstract=Gastric cancer usually arises in middle-aged to older patients, and is rarely found in younger patients. The clin-ical characteristics, etiology, prognosis, preventive methods and treatment of gastric cancer in young patients have not been fully investigated because of its low prevalence. In this review, we discuss the current under-standing and clinical problems associated with gastric cancer in young patients. Helicobacter pylori (H. pylori), which is a major cause of gastric cancer, especially in older populations, is closely associated with gastric cancer in young patients as well as in older patients. Gastric cancer in young patients tends to be diagnosed at an advanced stage with alarm symptoms. However, young patients with advanced gastric cancer tend to have a favorable general condition and organ function, so they can tolerate intensive systematic chemotherapy. Unfortunately, the prognosis of gastric cancer in young patients with an advanced stage is not favorable. We should not take this rare disease lightly, given its poor prognosis if patients are diagnosed at an unresectable stage. The evaluation of the H. pylori infection status and performance of H. pylori eradication therapy to prevent gastric cancer in young patients as well as the development of more intensive chemotherapy regimens for unre-sectable gastric cancer in young patients are warranted. en-copyright= kn-copyright= en-aut-name=KonoYoshiyasu en-aut-sei=Kono en-aut-mei=Yoshiyasu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 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=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=KawanoSeiji en-aut-sei=Kawano en-aut-mei=Seiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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= en-keyword=gastric cancer kn-keyword=gastric cancer en-keyword=young patients kn-keyword=young patients en-keyword=Helicobacter pylori kn-keyword=Helicobacter pylori END start-ver=1.4 cd-journal=joma no-vol=35 cd-vols= no-issue= article-no= start-page=1895 end-page=1902 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20201102 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Treatment outcomes, including risk factors of stone recurrence, for hepatolithiasis using balloon-assisted endoscopy in patients with hepaticojejunostomy (with video) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background and study aimsa
Endoscopic treatment outcomes for hepatolithiasis in patients with altered anatomy are not well known. The aim of this study was to evaluate the treatment outcomes of hepatolithiasis in patients with hepaticojejunostomy (HJ) using short-type double-balloon endoscopy (sDBE) and to assess the risk factors for stone recurrence.
Patients and methods
This was a retrospective cohort study that consisted of 73 patients with hepatolithiasis who underwent bowel reconstruction with HJ at an academic center. Stone removal was performed using sDBE. After balloon-occluded cholangiography using sDBE, peroral direct cholangioscopy (PDCS) using ultraslim endoscopy was performed to check for residual stones, depending on the bowel reconstruction method. Recurrence was defined as the development of cholangitis from stones.
Results
The success rate of reaching the HJ site was 92% (67/73), and the complete stone removal rate was 93% (62/67) with multiple sessions (mean number 1.5 ± 0.9). The occurrence rate of procedure-related adverse events was 6.8%. Among 58 patients evaluated for stone recurrence, 13 (22%) developed recurrence during a median follow-up period of 2.7 years (interquartile range: 1.5–4.8). Multivariate analyses determined that a stone diameter ≥ 8 mm [odds ratio (OR), 5.57; 95% confidence interval (CI), 1.39–37.2; p = 0.013] and performing PDCS (OR, 0.16; 95% CI, 0.0084–0.90; p = 0.036) were significant factors for stone recurrence.
Conclusions
Endoscopic treatment using sDBE for hepatolithiasis was effective and safe. PDCS might reduce the rate of stone recurrence by detecting stones that are too small to confirm on fluoroscopic images. en-copyright= kn-copyright= en-aut-name=IshiharaYuki en-aut-sei=Ishihara en-aut-mei=Yuki 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=KatoHironari en-aut-sei=Kato en-aut-mei=Hironari kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=TomodaTakeshi en-aut-sei=Tomoda en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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=11 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=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, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=2 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=10 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Dentistry and Pharmaceutical Sciences, Okayama University Graduate School of Medicine kn-affil= en-keyword=Peroral direct cholangioscopy kn-keyword=Peroral direct cholangioscopy en-keyword=Hepatolithiasis kn-keyword=Hepatolithiasis en-keyword=Altered gastrointestinal anatomy kn-keyword=Altered gastrointestinal anatomy en-keyword=Double-balloon endoscopy kn-keyword=Double-balloon endoscopy END start-ver=1.4 cd-journal=joma no-vol=33 cd-vols= no-issue= article-no= start-page=656 end-page=662 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200902 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Efficacy of low dose rectal diclofenac for preventing post‐endoscopic retrograde cholangiopancreatography pancreatitis: Propensity score‐matched analysis en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Acute pancreatitis is a major adverse event of endoscopic retrograde cholangiopancreatography (ERCP). Rectal administration of non‐steroidal anti‐inflammatory drugs (NSAIDs) decreases the incidence of post‐ERCP pancreatitis (PEP). However, the efficacy of low dose rectal NSAIDs for preventing PEP remains controversial.
Methods
We performed a retrospective study of 301 patients with native papilla and a body weight of <50 kg who underwent ERCP between September 2010 and October 2019. After July 2016, a 25 mg dose of rectal diclofenac was routinely administered within 15 min before ERCP (NSAIDs group, n = 72) and the control group (n = 229) consisted of patients undergoing ERCP before this date without treatment. We compared the incidence of PEP between the two groups using propensity score matching.
Results
A total of 66 pairs of patients in each group were selected. The patients and procedural‐related factors were similar in both groups. In total, 15 patients (11.4%) developed PEP: 12.1% (8/66) in the NSAIDs group and 10.6% (7/66) in the control group (Odds ratio (OR) 1.2; 95% confidence interval (CI) 0.4–3.5; P = 0.78). There was no significant difference in incidence of other adverse events related to ERCP between the two groups.
Conclusions
Prophylactic administration of a 25 mg dose of rectal diclofenac did not reduce the incidence of PEP in patients with a native papilla and a body weight of <50 kg in this study and a certain dose of rectal NSAIDs, such as a 100‐mg dose, should be administered regardless of body weight to prevent PEP. en-copyright= kn-copyright= en-aut-name=TomodaTakeshi en-aut-sei=Tomoda en-aut-mei=Takeshi 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=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiYuuki en-aut-sei=Fujii en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaragaiYousuke en-aut-sei=Saragai en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 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=9 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=10 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=11 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=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 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital 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= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=diclofenac kn-keyword=diclofenac en-keyword=low dose kn-keyword=low dose en-keyword=post‐ERCP pancreatitis kn-keyword=post‐ERCP pancreatitis END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=319 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200929 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The efficacy of pancreatic juice cytology with liquid-based cytology for evaluating malignancy in patients with intraductal papillary mucinous neoplasm en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Pancreatic juice cytology (PJC) is a tool for diagnosing malignant intraductal papillary mucinous neoplasm (IPMN); however, the accuracy is insufficient using the conventional method. Liquid-based cytology (LBC) improves the cell recovery rate, and almost all cells can be evaluated. We evaluated the efficacy of PJC with LBC for malignant IPMN.
Methods
We retrospectively analyzed 90 patients with suspected malignant IPMN who underwent PJC before pancreatectomy. PJC with smear and LBC methods was conducted in 52 patients (between June 2003 to December 2011) and 38 patients (between January 2012 to December 2018). Based on the imaging studies, all of the patients were classified according to the international consensus guidelines for IPMN revised in 2017.
Results
Of the 90 patients, 43 (48%) had malignant IPMN (high-grade dysplasia or invasive carcinoma), and the remaining patients had non-malignant IPMN (intermediate- or low-grade dysplasia). LBC increased the accuracy of PJC for the diagnosis of malignant IPMN (smear method: 56% [29/52] vs. LBC method: 76% [29/38]; P = 0.044). In a multivariate analysis, LBC was a significant factor influencing the accurate diagnosis of PJC (odds ratio: 3.52; P = 0.021). Furthermore, LBC increased the accuracy of PJC for malignant IPMN in patients with worrisome features (smear method: 66% [19/29] vs. LBC method: 93% [14/15]; P = 0.043).
Conclusions
LBC increases the accuracy of PJC for diagnosing malignant IPMN compared with the conventional smear method. en-copyright= kn-copyright= en-aut-name=MiyamotoKazuya en-aut-sei=Miyamoto

advanced non-small cell lung cancer (NSCLC) patients has improved in recent decades, especially for patients with an oncogenic driver mutation. Anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitors (TKIs) are effective for patients with the echinoderm microtubule-associated protein-like 4-ALK fusion gene. Several ALK-TKIs have been established: the first-generation ALK-TKI, crizotinib; second-generation ALK-TKIs, alectinib and ceritinib; and third-generation ALK-TKI, lorlatinib. Some ALK-TKIs are effective for tumors that are resistant to other ALK-TKIs; however, as is known in epidermal growth factor receptormutant lung cancer, tumor resistance is inevitable. ALK-positive NSCLCs acquire resistance via various mechanisms, making it a heterogeneous disease. Therefore, it is necessary to develop next-generation treatment strategies, such as the use of next-generation ALK-TKIs for secondary mutations, or combination therapies with ALK-TKIs and other TKIs. In this review, we summarize the development and use of ALK-TKIs, prior pivotal clinical trials, and resistance mechanisms. en-copyright= kn-copyright= en-aut-name=MakimotoGo en-aut-sei=Makimoto en-aut-mei=Go kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OhashiKadoaki en-aut-sei=Ohashi en-aut-mei=Kadoaki 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=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= affil-num=1 en-affil=Department of Respiratory Medicine, National Hospital Organization Iwakuni Clinical Center kn-affil= affil-num=2 en-affil=Department of 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 Respiratory Medicine, Okayama University Hospital kn-affil= en-keyword=lung cancer kn-keyword=lung cancer en-keyword=anaplastic lymphoma kinase kn-keyword=anaplastic lymphoma kinase en-keyword=tyrosine kinase inhibitors kn-keyword=tyrosine kinase inhibitors en-keyword=resistance mechanism kn-keyword=resistance mechanism END start-ver=1.4 cd-journal=joma no-vol=10 cd-vols= no-issue=1 article-no= start-page=14928 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200910 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dysfunction of CD8+PD-1+T cells in type 2 diabetes caused by the impairment of metabolism-immune axis en-subtitle= kn-subtitle= en-abstract= kn-abstract=The metabolic changes and dysfunction in CD8+T cells may be involved in tumor progression and susceptibility to virus infection in type 2 diabetes (T2D). In C57BL/6JJcl mice fed with high fat-high sucrose chow (HFS), multifunctionality of CD8+splenic and tumor-infiltrating lymphocytes (TILs) was impaired and associated with enhanced tumor growth, which were inhibited by metformin. In CD8+splenic T cells from the HFS mice, glycolysis/basal respiration ratio was significantly reduced and reversed by metformin. In the patients with T2D (DM), multifunctionality of circulating CD8+PD-1+T cells stimulated with PMA/ionomycin as well as with HLA-A*24:02 CMV peptide was dampened, while metformin recovered multifunctionality. Both glycolysis and basal respiration were reduced in DM, and glycolysis was increased by metformin. The disturbance of the link between metabolism and immune function in CD8+PD-1+T cells in T2D was proved by recovery of antigen-specific and non-specific cytokine production via metformin-mediated increase in glycolytic activity. en-copyright= kn-copyright= en-aut-name=NojimaIchiro en-aut-sei=Nojima en-aut-mei=Ichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=EikawaShingo en-aut-sei=Eikawa en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TomonobuNahoko en-aut-sei=Tomonobu en-aut-mei=Nahoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HadaYoshiko en-aut-sei=Hada en-aut-mei=Yoshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KajitaniNobuo en-aut-sei=Kajitani en-aut-mei=Nobuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=TeshigawaraSanae en-aut-sei=Teshigawara en-aut-mei=Sanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ToneAtsuhito en-aut-sei=Tone en-aut-mei=Atsuhito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= en-aut-name=NakatsukaAtsuko en-aut-sei=Nakatsuka en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 ORCID= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=UdonoHeiichiro en-aut-sei=Udono en-aut-mei=Heiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=14 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 Hematology/Oncology, Hess Cancer Institute, Icahn School of Medicine At Mount Sinai kn-affil= affil-num=3 en-affil=Department of Cell Biology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=4 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Internal Medicine, Diabetes Center, Okayama City Hospital kn-affil= affil-num=6 en-affil=Diabetes Center, Okayama S kn-affil=italama Univ, Dept Med & Clin Sci, Grad Sch Med Dent & Pharmaceut Sci affil-num=7 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=8 en-affil=Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=9 en-affil=Department of Chronic Kidney Disease and Cardiovascular Disease, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=10 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=11 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=12 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Immunology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=14 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Cytokines kn-keyword=Cytokines en-keyword=Diabetes kn-keyword=Diabetes en-keyword=Endocrine system and metabolic diseases kn-keyword=Endocrine system and metabolic diseases en-keyword=Immunology kn-keyword=Immunology en-keyword=Tumour immunology kn-keyword=Tumour immunology END start-ver=1.4 cd-journal=joma no-vol=12 cd-vols= no-issue=2 article-no= start-page=207 end-page=216 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200808 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Randomized trial of an intensified, multifactorial intervention in patients with advanced‐stage diabetic kidney disease: Diabetic Nephropathy Remission and Regression Team Trial in Japan (DNETT‐Japan) en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/Introduction
We evaluated the efficacy of multifactorial intensive treatment (IT) on renal outcomes in patients with type 2 diabetes and advanced‐stage diabetic kidney disease (DKD).
Materials and Methods
The Diabetic Nephropathy Remission and Regression Team Trial in Japan (DNETT‐Japan) is a multicenter, open‐label, randomized controlled trial with a 5‐year follow‐up period. We randomly assigned 164 patients with advanced‐stage diabetic kidney disease (urinary albumin‐to‐creatinine ratio ≥300 mg/g creatinine, serum creatinine level 1.2–2.5 mg/dL in men and 1.0–2.5 mg/dL in women) to receive either IT or conventional treatment. The primary composite outcome was end‐stage kidney failure, doubling of serum creatinine or death from any cause, which was assessed in the intention‐to‐treat population.
Results
The IT tended to reduce the risk of primary end‐points as compared with conventional treatment, but the difference between treatment groups did not reach the statistically significant level (hazard ratio 0.69, 95% confidence interval 0.43–1.11; P = 0.13). Meanwhile, the decrease in serum low‐density lipoprotein cholesterol level and the use of statin were significantly associated with the decrease in primary outcome (hazard ratio 1.14; 95% confidence interval 1.05–1.23, P < 0.001 and hazard ratio 0.53, 95% confidence interval 0.28–0.998, P < 0.05, respectively). The incidence of adverse events was not different between treatment groups.
Conclusions
The risk of kidney events tended to decrease by IT, although it was not statistically significant. Lipid control using statin was associated with a lower risk of adverse kidney events. Further follow‐up study might show the effect of IT in patients with advanced diabetic kidney disease. en-copyright= kn-copyright= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HanedaMasakazu en-aut-sei=Haneda en-aut-mei=Masakazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NinomiyaToshiharu en-aut-sei=Ninomiya en-aut-mei=Toshiharu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KoyaDaisuke en-aut-sei=Koya en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SuzukiYoshiki en-aut-sei=Suzuki en-aut-mei=Yoshiki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=SuzukiDaisuke en-aut-sei=Suzuki en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=IshidaHitoshi en-aut-sei=Ishida en-aut-mei=Hitoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=AkaiHiroaki en-aut-sei=Akai en-aut-mei=Hiroaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=TominoYasuhiko en-aut-sei=Tomino en-aut-mei=Yasuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=UzuTakashi en-aut-sei=Uzu en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=NishimuraMotonobu en-aut-sei=Nishimura en-aut-mei=Motonobu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=MaedaShiro en-aut-sei=Maeda en-aut-mei=Shiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=OgawaDaisuke en-aut-sei=Ogawa en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=MakinoHirofumi en-aut-sei=Makino en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= en-aut-name=the Diabetic Nephropathy Remission and Regression Team Trial in Japan (DNETT‐Japan) collaborative group en-aut-sei=the Diabetic Nephropathy Remission and Regression Team Trial in Japan (DNETT‐Japan) collaborative group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=16 ORCID= affil-num=1 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=2 en-affil=Division of Metabolism and Biosystemic Science, Department of Medicine, Asahikawa Medical University kn-affil= affil-num=3 en-affil=Department of Epidemiology and Public Health, Graduate School of Medical Sciences, Kyushu University kn-affil= affil-num=4 en-affil=Department of Diabetology & Endocrinology, Kanazawa Medical University kn-affil= affil-num=5 en-affil=Health Administration Center, Niigata University kn-affil= affil-num=6 en-affil=Suzuki Diabetes Clinic kn-affil= affil-num=7 en-affil=Research Center for Health Care, Nagahama City Hospital kn-affil= affil-num=8 en-affil=Division of Metabolism and Diabetes, Tohoku Medical and Pharmaceutical University kn-affil= affil-num=9 en-affil=Division of Nephrology, Department of Internal Medicine, Juntendo University Faculty of Medicine kn-affil= affil-num=10 en-affil=Division of Nephrology, Department of Medicine, Nippon Life Hospital kn-affil= affil-num=11 en-affil=Department of Diabetes and Endocrinology, National Hospital Organization Chiba‐East National Hospital kn-affil= affil-num=12 en-affil=Department of Advanced Genomic and Laboratory Medicine, Graduate School of Medicine, University of the Ryukyus kn-affil= affil-num=13 en-affil=Okayama Diabetes and Neurology Clinic kn-affil= affil-num=14 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=15 en-affil=Okayama University kn-affil= affil-num=16 en-affil= kn-affil= en-keyword=Diabetic kidney disease kn-keyword=Diabetic kidney disease en-keyword=Diabetic nephropathy kn-keyword=Diabetic nephropathy en-keyword=Diabetic Nephropathy Remission and Regression Team Trial in Japan kn-keyword=Diabetic Nephropathy Remission and Regression Team Trial in Japan END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=4 article-no= start-page=285 end-page=291 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202008 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparison of Two Different Intensive Care Unit Systems for Severely Ill Children in Japan: Data from the JaRPAC Registry en-subtitle= kn-subtitle= en-abstract= kn-abstract=The importance of centralizing treatment services for severely ill children has been well established, but such entralization remains difficult in Japan. We aimed to compare the trauma and illness severity and mortality of children admitted to two common types of ICUs for children. According to the type of management and disposition of the medical provider, we classified ICUs as pediatric ICUs [PICUs] or general ICUs, and analyzed differences in endogenous and exogenous illness settings between them. Overall, 1,333 pediatric patients were included, with 1,143 patients admitted to PICUs and 190 patients to general ICUs. The Pediatric Cerebral Performance Category score (PCPC) at discharge was significantly lower in the PICU group (adjusted OR: 0.45; 95%CI: 0.23-0.88). Death and unfavorable neurological outcomes occurred less often in the PICU group (adjusted OR: 0.29; 95%CI: 0.14-0.60). However, when limited to exogenous illness, PCPC scores (adjusted OR: 0.38; 95%CI: 0.07-1.99) or death/unfavorable outcomes (adjusted OR: 0.72; 95%CI: 0.08-6.34) did not differ between the groups. PCPC deterioration and overall sequelae/death rates were lower in PICUs for children with endogenous illnesses, although the outcomes of exogenous illness were similar between the 2 unit types. Further studies on the necessity of centralization are warranted. en-copyright= kn-copyright= en-aut-name=TsukaharaKohei en-aut-sei=Tsukahara en-aut-mei=Kohei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=NaitouHiromichi en-aut-sei=Naitou en-aut-mei=Hiromichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 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=3 ORCID= en-aut-name=NosakaNobuyuki en-aut-sei=Nosaka en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YamamotoHirotsugu en-aut-sei=Yamamoto en-aut-mei=Hirotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OsakoTakaaki en-aut-sei=Osako en-aut-mei=Takaaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 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=7 ORCID= en-aut-name=the JaRPAC Study Group en-aut-sei=the JaRPAC Study Group en-aut-mei= kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences 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 Pediatrics, Cedars-Sinai Medical Center kn-affil= affil-num=5 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Department of Emergency, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=8 en-affil= kn-affil= en-keyword=kids kn-keyword=kids en-keyword=critical care kn-keyword=critical care en-keyword=mortality kn-keyword=mortality en-keyword=morbidity kn-keyword=morbidity en-keyword=centralization kn-keyword=centralization END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page=521 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200605 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prognostic value of OCT4A and SPP1C transcript variant co-expression in early-stage lung adenocarcinoma en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Octamer-binding transcription factor 4A (OCT4A) is essential for cell pluripotency and reprogramming both in humans and mice. To date, however, the function of human OCT4 in somatic and/or tumour tissues is largely unknown.
Methods
RT-PCR was used to identify full-length splice forms of OCT4 transcripts in normal and cancer cells. A FLAG-tagged OCT4 genomic transgene was used to identify OCT4-positive cancer cells. A potential role for OCT4 in somatic cancer cells was examined by cell ablation of OCT4-positive cells using promoter-driven diphtheria toxin A. OCT4 and secreted phosphoprotein 1 (SPP1) transcripts in early-stage lung adenocarcinoma tumours were analysed and compared with pathohistological features.
Results
The results show that, unlike in murine cells, OCT4A and OCT4B variants are transcribed in both human cancer cells and in adult tissues such as lung, kidney, uterus, breast, and eye. We found that OCT4A and SPP1C are co-expressed in highly aggressive human breast, endometrial, and lung adenocarcinoma cell lines, but not in mesothelial tumour cell lines. Ablation of OCT4-positive cells in lung adenocarcinoma cells significantly decreased cell migration and SPP1C mRNA levels. The OCT4A/SPP1C axis was found in primary, early-stage, lung adenocarcinoma tumours.
Conclusions
Co-expression of OCT4 and SPP1 may correlate with cancer aggressiveness, and the OCT4A/SPP1C axis may help identify early-stage high-risk patients with lung adenocarcinoma. Contrary to the case in mice, our data strongly suggest a critical role for OCT4A and SPP1C in the development and progression of human epithelial cancers. en-copyright= kn-copyright= en-aut-name=KoshimuneSeijiro en-aut-sei=Koshimune en-aut-mei=Seijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KosakaMitsuko en-aut-sei=Kosaka en-aut-mei=Mitsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MizunoNobuhiko en-aut-sei=Mizuno en-aut-mei=Nobuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= en-aut-name=MiyamotoTomoyuki en-aut-sei=Miyamoto en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=EbisuiKohta en-aut-sei=Ebisui en-aut-mei=Kohta 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=OhtsukaAiji en-aut-sei=Ohtsuka en-aut-mei=Aiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Okayama Univ, Dept Human Morphol, Grad Sch Med Dent & Pharmaceut Sci kn-affil= affil-num=3 en-affil=Department of Human Morphology, 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 Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Human Morphology, 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 Human Morphology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=OCT4 kn-keyword=OCT4 en-keyword=SPP1 kn-keyword=SPP1 en-keyword=lung adenocarcinoma kn-keyword=lung adenocarcinoma en-keyword=tumour-initiating cell kn-keyword=tumour-initiating cell en-keyword=cancer stem cell kn-keyword=cancer stem cell en-keyword=cell migration kn-keyword=cell migration END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=245 end-page=250 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202006 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Effect of Vonoprazan on Delayed Bleeding after Endoscopic Submucosal Dissection for Gastric Neoplasia among Antithrombotic Drug Users: A Single-Center, Single-Arm Prospective Observational Case Control Study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Antithrombotic therapy is a major risk factor for delayed bleeding after endoscopic submucosal dissection (ESD) for gastric neoplasia. A potassium-competitive acid blocker, vonoprazan, is expected to prevent delayed bleeding better than conventional proton pomp inhibitors (PPIs), but the evidence is controversial. We sought to clarify the efficacy of vonoprazan for prevention of delayed bleeding after gastric ESD in patients under antithrombotic therapy. We prospectively registered 50 patients who underwent gastric ESD while receiving antithrombotic therapy and vonoprazan in our institution between October 2017 and September 2018. The incidence of delayed bleeding was compared with that in a historical control group of 116 patients treated with conventional PPI. We also evaluated risk factors associated with delayed bleeding. Delayed bleeding was observed in 8 of 50 patients (16.0%), which was not dissimilar from the incidence in the historical control group (12.1%) (p=0.49). In the univariate analysis, age (> 70 years) (p=0.034), multiple antithrombotic drug use (p<0.01), procedure time (> 200 min) (p=0.038) and tumor size (> 40 mm) (p<0.01) were associated with delayed bleeding after gastric ESD, but vonoprazan was not (p=0.49). Vonoprazan may not be more effective than conventional PPIs in preventing delayed bleeding after gastric ESD in patients receiving antithrombotic therapy. en-copyright= kn-copyright= en-aut-name=YamamotoShumpei en-aut-sei=Yamamoto en-aut-mei=Shumpei kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TakayamaHiroshi en-aut-sei=Takayama en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShimodateYuichi en-aut-sei=Shimodate en-aut-mei=Yuichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TakezawaRio en-aut-sei=Takezawa en-aut-mei=Rio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishimuraNaoyuki en-aut-sei=Nishimura en-aut-mei=Naoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=DoiAkira en-aut-sei=Doi en-aut-mei=Akira kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MouriHirokazu en-aut-sei=Mouri en-aut-mei=Hirokazu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=MizunoMotowo en-aut-sei=Mizuno en-aut-mei=Motowo 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, Kurashiki Central Hospital kn-affil= affil-num=3 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central 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 Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=7 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=8 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital kn-affil= affil-num=9 en-affil=Department of Gastroenterology and Hepatology, Kurashiki Central Hospital 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=vonoprazan kn-keyword=vonoprazan en-keyword=endoscopic submucosal dissection kn-keyword=endoscopic submucosal dissection en-keyword=antithrombotic drug kn-keyword=antithrombotic drug en-keyword=gastric cancer kn-keyword=gastric cancer END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=3 article-no= start-page=199 end-page=208 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202006 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dkk3/REIC, an N-glycosylated Protein, Is a Physiological Endoplasmic Reticulum Stress Inducer in the Mouse Adrenal Gland en-subtitle= kn-subtitle= en-abstract= kn-abstract=Dickkopf 3 (Dkk3) is a secreted protein belonging to the Dkk family and encoded by the orthologous gene of REIC. Dkk3/REIC is expressed by mouse and human adrenal glands, but the understanding of its roles in this organ is still limited. To determine the functions of Dkk3 in the mouse adrenal gland, we first identified that the mouse Dkk3 protein is N-glycosylated in the adrenal gland as well as in the brain. We performed proteome analysis on adrenal glands from Dkk3-null mice, in which exons 5 and 6 of the Dkk3 gene are deleted. Twodimensional polyacrylamide gel electrophoresis of adrenal proteins from wild-type and Dkk3-null mice revealed 5 protein spots whose intensities were altered between the 2 genotypes. Mass spectrometry analysis of these spots identified binding immunoglobulin protein (BiP), an endoplasmic reticulum (ER) chaperone. To determine whether mouse Dkk3 is involved in the unfolded protein response (UPR), we carried out a reporter assay using ER-stress responsive elements. Forced expression of Dkk3 resulted in the induction of distinct levels of reporter expression, showing the UPR initiated by the ER membrane proteins of activating transcription factor 6 (ATF6) and inositol-requring enzyme 1 (IRE1). Thus, it is possible that Dkk3 is a physiological ER stressor in the mouse adrenal gland. en-copyright= kn-copyright= en-aut-name=FujitaHirofumi en-aut-sei=Fujita en-aut-mei=Hirofumi kn-aut-name=

en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
To evaluate the outcomes of endoscopic retrograde cholangiopancreatography (ERCP) for malignant biliary obstruction (MBO) using short-type double-balloon enteroscope (sDBE) in patients with surgically altered anatomy.
Methods
A total of 45 patients with surgically altered anatomy underwent ERCP using sDBE for the treatment of MBO between April 2011 and March 2019. We retrospectively evaluated the clinical and technical success (insertion and biliary intervention success), adverse events, and risk factors for clinical failure.
Results
The scope was successfully inserted in the target site in 82.2% of patients (37/45), and among them, biliary intervention success was achieved in 86.4% (32/37). The overall technical success rate was 71.1% (32/45) and clinical success rate was 68.9% (31/45), with an adverse event rate of 11.1%. In multivariate analysis, the presence of peritoneal dissemination (odds ratio, 7.3; 95% confidence interval, 1.5–43.5, p = 0.02) was as an independent risk factor for clinical failure. The clinical success rate was 38.5% in patients with peritoneal dissemination and 81.3% in those without peritoneal dissemination.
Conclusion
Endoscopic treatment using sDBE in patients without peritoneal dissemination provided favorable outcomes, and it can be an initial treatment for MBO in patients with surgically altered anatomy.
Endoscopic biliary stent placement with endoscopic retrograde cholangiography (ERCP) for the treatment of malignant biliary obstruction (MBO) has been widely accepted as an effective drainage method because it is less invasive and safe and has a high success rate (1–3). However, MBO is treated using percutaneous transhepatic biliary drainage (PTBD) or surgical bypass because of difficulties related to endoscopic access to the bile duct following gastrointestinal reconstruction. However, these methods are associated with marked adverse event (AE) rates [1,2,3].
Recently, balloon-assisted endoscopy (BAE) facilitates ERCP in patients with surgically altered anatomy. As for a double-balloon enteroscope (DBE), a short-type DBE (sDBE) is especially useful because it allows the use of many standard ERCP accessories.
The success rates of reaching the target site and ERCP-related interventions associated using these endoscopes range from 73–100% and 85–100%, respectively [4, 5]. We previously reported that the success rate of reaching the target site and biliary intervention was 93.8% and 95.7%, respectively, in patients with benign hepaticojejunostomy (HJ) anastomotic stricture [6].
However, inaccessibility of the target site may occur due to severe postoperative adhesions or a long insertion time (i.e., > 60 min). Furthermore, previous reports have shown that the success rate of BAE in MBO cases was significantly lower than that in benign biliary diseases [7, 8]. Few reports have investigated the outcome of BAE for MBO in patients with surgically altered anatomy. Additionally, the risk factors for clinical failure are not well-established.
Thus, we retrospectively evaluated the outcomes of endoscopic treatment for MBO using sDBE in patients with surgically altered anatomy and identified risk factors for clinical failure. en-copyright= kn-copyright= en-aut-name=TomodaTakeshi en-aut-sei=Tomoda en-aut-mei=Takeshi 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=MiyamotoKazuya en-aut-sei=Miyamoto en-aut-mei=Kazuya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MatsumiAkihiro en-aut-sei=Matsumi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=UetaEijiro en-aut-sei=Ueta en-aut-mei=Eijiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=FujiiYuuki en-aut-sei=Fujii en-aut-mei=Yuuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SaragaiYousuke en-aut-sei=Saragai en-aut-mei=Yousuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 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=8 ORCID= en-aut-name=chidaDaisuke en-aut-sei=chida en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=atsumotoKazuyuki en-aut-sei=atsumoto en-aut-mei=Kazuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 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=11 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=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 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 Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital 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= affil-num=11 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= affil-num=13 en-affil=Department of Gastroenterology and Hepatology, Okayama University Hospital kn-affil= en-keyword=Malignant biliary obstruction kn-keyword=Malignant biliary obstruction en-keyword= Double-balloon enteroscope kn-keyword= Double-balloon enteroscope en-keyword=Endoscopic retrograde cholangiopancreatography kn-keyword=Endoscopic retrograde cholangiopancreatography en-keyword=Surgically altered anatomy kn-keyword=Surgically altered anatomy END start-ver=1.4 cd-journal=joma no-vol=74 cd-vols= no-issue=2 article-no= start-page=95 end-page=101 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=202004 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The Efficacy of Software to Help Patients Understand Drug for Adjuvant Treatment for Breast Cancer: A Pilot Randomized Controlled Trial en-subtitle= kn-subtitle= en-abstract= kn-abstract= We assessed the usefulness of ChemoCalc, a software package for calculating drug costs, in helping patients understand these costs. We randomly assigned, in a 1 : 1 ratio, 20 women who had undergone surgery for early breast cancer to a group that discussed adjuvant treatment with their physicians using the ChemoCalc software (ChemoCalc group) or a group that discussed adjuvant treatment without ChemoCalc (Usual Explanation group). The participants completed a five-grade evaluation questionnaire after these discussions. The primary endpoint was the intergroup comparison of the questionnaire scores regarding participants’ understanding of their treatment-associated drug costs. Median age was not significantly different between the ChemoCalc group and Usual Explanation group (57 vs. 50, respectively; p=0.27). Patients in the ChemoCalc group had a significantly higher perceived level of understanding of the drug cost than those in the Usual Explanation group (5 [4-5] vs. 2.5 [1-5], respectively; p=0.002). Scores related to the patients’ perception that understanding drug costs is an important part of breast cancer treatment were also higher in the ChemoCalc group than the Usual Explanation group (5 [2-5] vs. 3 [1-5], respectively; p=0.049). ChemoCalc was found to be useful for understanding drug costs. en-copyright= kn-copyright= en-aut-name=KubaSayaka en-aut-sei=Kuba en-aut-mei=Sayaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YamanouchiKosho en-aut-sei=Yamanouchi en-aut-mei=Kosho kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoritaMichi en-aut-sei=Morita en-aut-mei=Michi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SakimuraChika en-aut-sei=Sakimura en-aut-mei=Chika kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=InamasuEiko en-aut-sei=Inamasu en-aut-mei=Eiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=HatachiToshiko en-aut-sei=Hatachi en-aut-mei=Toshiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OtsuboRyota en-aut-sei=Otsubo en-aut-mei=Ryota kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=MatsumotoMegumi en-aut-sei=Matsumoto en-aut-mei=Megumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YanoHiroshi en-aut-sei=Yano en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MiyamotoJunya en-aut-sei=Miyamoto en-aut-mei=Junya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=SatoShuntaro en-aut-sei=Sato en-aut-mei=Shuntaro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=NakagawaHiroo en-aut-sei=Nakagawa en-aut-mei=Hiroo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=KanetakaKengo en-aut-sei=Kanetaka en-aut-mei=Kengo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=TakatsukiMitsuhisa en-aut-sei=Takatsuki en-aut-mei=Mitsuhisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=NagayasuTakeshi en-aut-sei=Nagayasu en-aut-mei=Takeshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 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=16 ORCID= affil-num=1 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=2 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=3 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=4 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=5 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=6 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=7 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=8 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=9 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=10 en-affil=Department of Clinical Research Center, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=11 en-affil=Department of Clinical Research Center, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=12 en-affil=Department of Pharmacy, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=13 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=14 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=15 en-affil=Department of Surgical Oncology, Nagasaki University Graduate School of Biomedical Science kn-affil= affil-num=16 en-affil=Department of Surgery, Nagasaki University Graduate School of Biomedical Science kn-affil= en-keyword=breast cancer kn-keyword=breast cancer en-keyword=drug costs kn-keyword=drug costs en-keyword=ChemoCalc kn-keyword=ChemoCalc END start-ver=1.4 cd-journal=joma no-vol=20 cd-vols= no-issue=1 article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200113 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hemophagocytic lymphohistiocytosis complicating invasive pneumococcal disease: a pediatric case report en-subtitle= kn-subtitle= en-abstract= kn-abstract=Background
Hemophagocytic lymphohistiocytosis (HLH) is an infrequent but life-threatening disease due to excessive immune activation. Secondary HLH can be triggered by infections, autoimmune diseases, and malignant diseases. Streptococcus pneumoniae is a pathogenic bacterium responsible for invasive pneumococcal disease (IPD) such as meningitis and bacteremia. Although the pneumococcal conjugate vaccine (PCV) has led to reductions in IPD incidence, cases of IPD caused by serotypes not included in PCV are increasing. There are few reports of secondary HLH caused by IPD in previously healthy children. We herein report a rare case of a previously healthy boy with secondary HLH complicating IPD of serotype 23A, which is not included in the pneumococcal 13-valent conjugate vaccine (PCV-13).
Case presentation
An 11-month-old boy who had received three doses of PCV-13 was hospitalized with prolonged fever, bilateral otitis media, neutropenia and elevated C-reactive protein (CRP) levels. Blood culture on admission revealed S. pneumoniae, leading to a diagnosis of IPD. HLH was diagnosed based on a prolonged fever, neutropenia, anemia, hepatosplenomegaly, hemophagocytosis in the bone marrow, and elevated serum levels of triglycerides, ferritin, and soluble interleukin-2 receptor. He received broad-spectrum antibiotics and intravenous immunoglobulins for IPD and high-dose steroid pulse therapy and cyclosporine A for HLH; thereafter, his fever resolved, and laboratory findings improved. The serotype of the isolated S. pneumoniae was 23A, which is not included in PCV-13.
Conclusions
It is important to consider secondary HLH as a complication of IPD cases with febrile cytopenia or hepatosplenomegaly, and appropriate treatment for HLH should be started without delay. en-copyright= kn-copyright= en-aut-name=TsugeMitsuru en-aut-sei=Tsuge en-aut-mei=Mitsuru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoMachiko en-aut-sei=Miyamoto en-aut-mei=Machiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyawakiReiji en-aut-sei=Miyawaki en-aut-mei=Reiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KondoYoichi en-aut-sei=Kondo en-aut-mei=Yoichi 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, Matsuyama Red Cross Hospital kn-affil= affil-num=3 en-affil=Department of Pediatrics,Ehime University Graduate School of Medicine kn-affil= affil-num=4 en-affil=Department of Pediatrics, Matsuyama Red Cross Hospital kn-affil= affil-num=5 en-affil=Department of Pediatrics, Matsuyama Red Cross Hospital kn-affil= en-keyword=Child kn-keyword=Child en-keyword=Hemophagocytic lymphohistiocytosis kn-keyword=Hemophagocytic lymphohistiocytosis en-keyword=Invasive pneumococcal disease kn-keyword=Invasive pneumococcal disease en-keyword=Pneumococcal conjugate vaccine kn-keyword=Pneumococcal conjugate vaccine en-keyword=Serotype replacement kn-keyword=Serotype replacement END start-ver=1.4 cd-journal=joma no-vol=11 cd-vols= no-issue=2 article-no= start-page=97 end-page=104 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190916 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=The hypoglycemia-prevention effect of sensor-augmented pump therapy with predictive low glucose management in Japanese patients with type 1 diabetes mellitus: a short-term study en-subtitle= kn-subtitle= en-abstract= kn-abstract=Aims/introduction
The predictive low glucose management (PLGM) system was introduced in March 2018 in Japan. Although there are some reports demonstrating the benefit of PLGM in preventing hypoglycemia, no data are currently available in Japanese patients with type 1 diabetes mellitus (T1DM). The aim of the present study is to evaluate the effect of PLGM with sensor-augmented pump therapy in the prevention of hypoglycemia in Japanese patients.
Materials and methods
We included 16 patients with T1DM who used the MiniMed®640G system after switching from the MiniMed®620G system. We retrospectively analysed the data of the continuous glucose monitoring system in 1 month after switching to MiniMed®640G.
Results
The area under the curve (AUC) of hypoglycemia of < 70 mg/dL was lowered from 0.42 ± 0.43 mg/dL day to 0.18 ± 0.18 mg/dL day (P = 0.012). Correspondingly, the duration of severe hypoglycemia (< 54 mg/dL) was reduced significantly from 15.3 ± 21.7 min/day to 4.8 ± 6.9 min/day (P = 0.019). The duration of hypoglycemia was reduced, but the reduction was not significant. Regarding the AUC for hyperglycemia > 180 mg/dL and the duration of hyperglycemia did not change. With the PLGM function, 79.3% of the predicted hypoglycemic events were avoided.
Conclusions
The hypoglycemia avoidance rate was comparable to those in previous reports. In addition, we demonstrated that PLGM can markedly suppress severe hypoglycemia without deteriorating glycemic control in Japanese T1DM patients. It is necessary to further investigate the effective use of the PLGM feature such as establishing a lower limit and the timing of resumption. en-copyright= kn-copyright= en-aut-name=KatayamaAkihiro en-aut-sei=Katayama en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ToneAtsuhito en-aut-sei=Tone en-aut-mei=Atsuhito 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=TeshigawaraSanae en-aut-sei=Teshigawara en-aut-mei=Sanae kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 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=6 ORCID= en-aut-name=NakatsukaAtsuko en-aut-sei=Nakatsuka en-aut-mei=Atsuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 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=9 ORCID= affil-num=1 en-affil=Diabetes Center, Okayama University Hospital kn-affil= affil-num=2 en-affil=Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=3 en-affil=Department of Primary Care and Medical Education, Okayama University kn-affil= affil-num=4 en-affil=Diabetes Center, Okayama Saiseikai General Hospital kn-affil= affil-num=5 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Nephrology, Rheumatology, Endocrinology and Metabolism, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=7 en-affil=Okayama Univ, Dept Med & Clin Sci, Grad Sch Med Dent & Pharmaceut Sci kn-affil= affil-num=8 en-affil=Center for Innovative Clinical Medicine, Okayama University Hospital kn-affil= affil-num=9 en-affil=Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University kn-affil= en-keyword=Hypoglycemia kn-keyword=Hypoglycemia en-keyword=Predictive low glucose management (PLGM) kn-keyword=Predictive low glucose management (PLGM) en-keyword=Type 1 diabetes mellitus (T1DM) kn-keyword=Type 1 diabetes mellitus (T1DM) en-keyword=Sensor-augmented pump therapy (SAP) kn-keyword=Sensor-augmented pump therapy (SAP) END start-ver=1.4 cd-journal=joma no-vol=913 cd-vols= no-issue= article-no= start-page=72 end-page=77 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=20190101 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Energy response of X-rays under high flux conditions using a thin APD for the energy range of 6–33 keV en-subtitle= kn-subtitle= en-abstract= kn-abstract= This paper reports on the demonstration of a high-rate energy measurement technique using a thin depletion layer silicon avalanche photodiode (Si-APD). A dedicated amplitude-to-time converter is developed to realize simultaneous energy and timing measurement in a high rate condition. The energy response of the system is systematically studied by using monochromatic X-ray beam with an incident energy ranging from 6 to 33 keV. The obtained energy spectra contain clear peaks and tail distributions. The peak fraction monotonously decreases as the incident photon energy increases. This phenomenon can be explained by considering the distribution of the energy deposit in silicon, which is investigated by using a Monte Carlo simulation. en-copyright= kn-copyright= en-aut-name=MasudaT. en-aut-sei=Masuda en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=HirakiT. en-aut-sei=Hiraki en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KainoH. en-aut-sei=Kaino en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=KishimotoS. en-aut-sei=Kishimoto en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=MiyamotoY. en-aut-sei=Miyamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=OkaiK. en-aut-sei=Okai en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkuboS. en-aut-sei=Okubo en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiR. en-aut-sei=Ozaki en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasaoN. en-aut-sei=Sasao en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SuzukiK. en-aut-sei=Suzuki en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UetakeS. en-aut-sei=Uetake en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YoshimiA. en-aut-sei=Yoshimi en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YoshimuraK. en-aut-sei=Yoshimura en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 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=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=High Energy Accelerator Research Organization kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=10 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=11 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=12 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=13 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= en-keyword=Avalanche photodiode kn-keyword=Avalanche photodiode en-keyword=X-ray kn-keyword=X-ray END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=4 article-no= start-page=285 end-page=297 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201908 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Dynamic Reorganization of Microtubule and Glioma Invasion en-subtitle= kn-subtitle= en-abstract= kn-abstract= Gliomas are characterized as highly diffuse infiltrating tumors, and currently available treatments such as surgery, radiation and chemotherapy are unfeasible or show limited efficacy against these tumors. Recent genetic and epigenetic analyses of glioma have revealed increasing evidence of the role of driver genetic alterations in glioma development and led to the identification of prognostic factors. Despite these findings, the survival rates of glioma patients remain low, and alternative treatments and novel targets are needed. Recent studies identified neural stem cells as the possible origin of gliomas, and some evidence has revealed shared functions and mechanisms between glioma cells and neurons, also supporting their similarity. The cytoskeleton plays important roles in the migration of normal cells as well as cancer cells. Recent reports have described a role for microtubules, a component of the cytoskeleton, in glioma invasion. Notably, several factors that regulate microtubule functions, such as microtubule-associated proteins, plus-end tracking proteins, or motor proteins, are upregulated in glioma tissues compared with normal tissue, and upregulation of these factors is associated with high invasiveness of glioma cells. In this review, we describe the mechanism of microtubules in glioma invasion and discuss the possibility of microtubule-targeted therapy to inhibit glioma invasion. en-copyright= kn-copyright= en-aut-name=OtaniYoshihiro en-aut-sei=Otani en-aut-mei=Yoshihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IchikawaTomotsugu en-aut-sei=Ichikawa en-aut-mei=Tomotsugu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=KurozumiKazuhiko en-aut-sei=Kurozumi en-aut-mei=Kazuhiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 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=4 ORCID= affil-num=1 en-affil=Department of Neurosurgery, The University of Texas Health Science Center at Houston kn-affil= affil-num=2 en-affil=Department of Neurosurgery, Kagawa Prefectural Central Hospital 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= en-keyword=glioma kn-keyword=glioma en-keyword=cytoskeletons kn-keyword=cytoskeletons en-keyword=invasion kn-keyword=invasion en-keyword=microtubules kn-keyword=microtubules END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=235 end-page=240 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prevalence of and Risk Factors for the Progression of Upper Cervical Lesions in Patients with Rheumatoid Arthritis en-subtitle= kn-subtitle= en-abstract= kn-abstract= We investigated the prevalence of and risk factors for the progression of upper cervical lesions (UCLs) in patients with rheumatoid arthritis (RA). A retrospective analysis of 49 patients with RA (4 males, 45 females) was conducted. The UCLs included atlanto-axial subluxation and vertical subluxation. We investigated the clinical factors including the Disease Activity Score 28 based on C-reactive protein (DAS28-CRP) and the modified Health Assessment Questionnaire-Disability Index as well as radiographic changes between the baseline (at May 2010 to April 2013) and final follow-up. Forty patients (81.6%) were classified as the non-progressive group, and the other 9 patients (18.4%) comprised the progressive group. The progressive group’s final CRP values, baseline or final MMP-3 levels, DAS28-CRP, and rate of pre-existing lesions at baseline were all significantly higher than those of the non-progressive group (p=0.017, p=0.043, p=0.002, p=0.008, p<0.001, and p=0.008 respectively). A multivariate logistic regression analysis demonstrated that DAS28-CRP at baseline was a risk factor for radiographic progression (p=0.018, odds ratio: 2.54, 95% confidence interval: 1.17-5.51). Our findings indicate that higher disease activity might influence the progression of UCLs in patients with RA. en-copyright= kn-copyright= en-aut-name=HoritaMasahiro en-aut-sei=Horita en-aut-mei=Masahiro 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=HashizumeKenzo en-aut-sei=Hashizume en-aut-mei=Kenzo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SugimotoYoshihisa en-aut-sei=Sugimoto en-aut-mei=Yoshihisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 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=5 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=6 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=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 Rehabilitation, Japan Labour Health and Walfare Organization, Okayama Rosai Hospital kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Okayama City Hospital kn-affil= affil-num=5 en-affil=Department of Medical Materials for Musculoskeletal Reconstruction, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=6 en-affil=Department of Intelligent Orthopaedic ystem, 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=rheumatoid arthritis kn-keyword=rheumatoid arthritis en-keyword=upper cervical spine lesion kn-keyword=upper cervical spine lesion en-keyword=risk factor kn-keyword=risk factor en-keyword=radiological progression kn-keyword=radiological progression END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=3 article-no= start-page=213 end-page=221 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201906 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Spiral Trajectory Modulation of Rheotaxic Motile Human Sperm in Cylindrical Microfluidic Channels of Different Inner Diameters en-subtitle= kn-subtitle= en-abstract= kn-abstract= We investigated the relationship between human sperm rheotaxis and motile sperm trajectories by using poly-(dimethylsiloxane) (PDMS)-based cylindrical microfluidic channels with inner diameters of 100 μm, 50 μm, and 70 μm, which corresponded to the inner diameter of the human isthmus, the length of a sperm and a diameter intermediate between the two, respectively. We counted the number of rheotaxic sperm and sperm with spiral motion. We also analyzed motile sperm trajectories. As the cylindrical channel diameter was decreased, the percentage of sperm cells exhibiting rheotaxis, the percentage of sperm cells exhibiting spiral motion, the frequency-to-diameter ratio of the sperm cells’ spiral trajectories, and the surface area of the microfluidic channel increased, while the flagellar motion at the channel wall decreased. The percentage of sperm exhibiting a spiral trajectory and the frequency-to-diameter ratio of the sperm cells’ spiral trajectories were thus affected by the channel diameter. Our findings suggest that the oviduct structure affects the swimming properties of sperm cells, guiding them from the uterus to the ampulla for egg fertilization. These results could contribute to the development of motile sperm-sorting microfluidic devices for assisted reproductive technologies. en-copyright= kn-copyright= en-aut-name=NishinaSaori en-aut-sei=Nishina en-aut-mei=Saori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MatsuuraKoji en-aut-sei=Matsuura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=NaruseKeiji en-aut-sei=Naruse en-aut-mei=Keiji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= affil-num=1 en-affil=Cardiovascular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Biomedical Engineering, Faculty of Engineering, Okayama University of Science kn-affil= affil-num=3 en-affil=Cardiovascular Physiology, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=sperm motility kn-keyword=sperm motility en-keyword=trajectory kn-keyword=trajectory en-keyword=microfluidic channel kn-keyword=microfluidic channel en-keyword=rheotaxis kn-keyword=rheotaxis en-keyword=oviduct structure kn-keyword=oviduct structure END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=2 article-no= start-page=135 end-page=146 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Collagen XVIII Deposition in the Basement Membrane Zone beneath the Newly Forming Epidermis during Wound Healing in Mice en-subtitle= kn-subtitle= en-abstract= kn-abstract= The basement membrane (BM) is composed of various extracellular molecules and regulates tissue regeneration and maintenance. Here, we demonstrate that collagen XVIII was spatiotemporally expressed in the BM during skin wound healing in a mouse excisional wound-splinting model. Re-epithelialization was detected at days 3 and 6 post-wounding. The ultrastructure of epidermal BM was discontinuous at day 3, whereas on day 6 a continuous BM was observed in the region proximal to the wound edge. Immunohistochemistry demonstrated that collagen XVIII was deposited in the BM zone beneath newly forming epidermis in day 3 and 6 wounds. Laminin-332, known to be the earliest BM component appearing in wounds, was colocalized with collagen XVIII in the epidermal BM zone at days 3 and 6. The deposition of α1(IV) collagen and nidogen-1 in the epidermal BM zone occurred later than that of collagen XVIII. We also observed the short isoform of collagen XVIII in the epidermal BM zone at day 3 post-wounding. Collectively, our results suggested that collagen XVIII plays a role in the formation of the dermal-epidermal junction during re-epithelialization, and that it is the short isoform that is involved in the early phase of re-epithelialization. en-copyright= kn-copyright= en-aut-name=MaebaTakahiro en-aut-sei=Maeba en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=YonezawaTomoko en-aut-sei=Yonezawa en-aut-mei=Tomoko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OnoMitsuaki en-aut-sei=Ono en-aut-mei=Mitsuaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=TomonoYasuko en-aut-sei=Tomono en-aut-mei=Yasuko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=HeljasvaaraRitva en-aut-sei=Heljasvaara en-aut-mei=Ritva kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=PihlajaniemiTaina en-aut-sei=Pihlajaniemi en-aut-mei=Taina kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=InagawaKiichi en-aut-sei=Inagawa en-aut-mei=Kiichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OohashiToshitaka en-aut-sei=Oohashi en-aut-mei=Toshitaka kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=2 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=3 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= affil-num=4 en-affil=Shigei Medical Research Institute kn-affil= affil-num=5 en-affil=Center for Cancer Biomarkers CCBIO, Department of Biomedicine, University of Bergen kn-affil= affil-num=6 en-affil=Oulu Center for Cell-Matrix Research, Biocenter Oulu, Faculty of Biochemistry and Molecular Medicine, University of Oulu kn-affil= affil-num=7 en-affil=Department of Plastic and Reconstructive Surgery, Kawasaki Medical School, Kurashiki kn-affil= affil-num=8 en-affil=Department of Molecular Biology and Biochemistry, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science kn-affil= en-keyword=collagen XVIII kn-keyword=collagen XVIII en-keyword=basement membrane kn-keyword=basement membrane en-keyword=wound healing kn-keyword=wound healing en-keyword=re-epithelialization kn-keyword=re-epithelialization en-keyword=skin kn-keyword=skin END start-ver=1.4 cd-journal=joma no-vol=73 cd-vols= no-issue=2 article-no= start-page=109 end-page=115 dt-received= dt-revised= dt-accepted= dt-pub-year=2019 dt-pub=201904 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Clinicopathological Features and Outcomes of Endoscopic Submucosal Dissection for Superficial Cancer of the Pharynx en-subtitle= kn-subtitle= en-abstract= kn-abstract= The efficacy and safety of endoscopic submucosal dissection (ESD) for superficial cancer of the pharynx are still unclear. To identify clinicopathological features of superficial pharyngeal cancer, and the efficacy and safety of ESD, we retrospectively assessed 70 pharyngeal cancers in 59 patients who underwent ESD. Of these patients, 61.0% and 50.8% had a history of esophageal cancer and head and neck cancer, respectively. The median tumor size was 15 mm, and 75.7% of the lesions were located at the piriform sinus. The en bloc resection rate was 94.9%. Treatment-related adverse events occurred in 8 cases, but there was no treatment-related death. The lateral margin was positive for neoplasm in 3 lesions (4.3%) and inconclusive in 27 lesions (38.6%), but no local recurrence was observed. Cervical lymph node metastasis was observed in 6 patients, and was successfully treated by cervical lymph node dissection. The three-year overall survival rate was 91.5% (95%CI: 76.6-97.3%) and the cause-specific survival rate was 97.6% (95%CI: 84.9-99.7%). In conclusion, ESD for superficial pharyngeal cancer was safe and effective. “Resect and watch” is probably a feasible and rational strategy for treatment of patients with superficial pharyngeal cancer. en-copyright= kn-copyright= en-aut-name=AbeMakoto en-aut-sei=Abe en-aut-mei=Makoto kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwamuroMasaya en-aut-sei=Iwamuro

This is done over the wavelength range of 5.048-10.21 mu m by using the vibrational transition of parahydrogen. The efficiency increases with the frequency of the signal photon. Considering experimental errors, our results are consistent with the theoretical prediction for the present experimental conditions. This study is an experimental demonstration of the frequency dependence of coherently amplified two-photon emission, and also presents its potential as a light source. en-copyright= kn-copyright= en-aut-name=HaraHideaki en-aut-sei=Hara en-aut-mei=Hideaki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoYuki en-aut-sei=Miyamoto en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HirakiTakahiro en-aut-sei=Hiraki en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MasudaTakahiko en-aut-sei=Masuda en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=SasaoNoboru en-aut-sei=Sasao en-aut-mei=Noboru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=UetakeSatoshi en-aut-sei=Uetake en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=YoshimiAkihiro en-aut-sei=Yoshimi en-aut-mei=Akihiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YoshimuraKoji en-aut-sei=Yoshimura en-aut-mei=Koji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=YoshimuraMotohiko en-aut-sei=Yoshimura en-aut-mei=Motohiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 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=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=8 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= END start-ver=1.4 cd-journal=joma no-vol=88 cd-vols= no-issue=6 article-no= start-page=063105 end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201706 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Fast x-ray detector system with simultaneous measurement of timing and energy for a single photon en-subtitle= kn-subtitle= en-abstract= kn-abstract= We developed a fast X-ray detector system for nuclear resonant scattering (NRS) experiments. Our system employs silicon avalanche photo-diode (Si-APD) as a fast X-ray sensor. The system is able to acquire both timing and energy of a single X-ray photon simultaneously in a high rate condition, 106 counts per second for one Si-APD. The performance of the system was investigated in SPring-8, a synchrotron radiation facility in Japan. Good time resolution of 120 ps (FWHM) was achieved with a slight tail distribution in the time spectrum by a level of 10-9 at 1 ns apart from the peak. Using this system, we successfully observed the NRS from the 26.27-keV level of mercury-201, which has a half-life of 630(50) ps. We also demonstrated the reduction of background events caused by radioactive decays in a radioactive sample by discriminating photon energy. en-copyright= kn-copyright= en-aut-name=MasudaTakahiko en-aut-sei=Masuda en-aut-mei=Takahiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=OkuboS. en-aut-sei=Okubo en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=HaraH. en-aut-sei=Hara en-aut-mei=H. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=HirakiT. en-aut-sei=Hiraki en-aut-mei=T. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KitaoS. en-aut-sei=Kitao en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MiyamotoY. en-aut-sei=Miyamoto en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkaiK. en-aut-sei=Okai en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=OzakiR. en-aut-sei=Ozaki en-aut-mei=R. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=SasaoN. en-aut-sei=Sasao en-aut-mei=N. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=SetoM. en-aut-sei=Seto en-aut-mei=M. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=UetakeS. en-aut-sei=Uetake en-aut-mei=S. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=YamaguchiA. en-aut-sei=Yamaguchi en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= en-aut-name=YodaY. en-aut-sei=Yoda en-aut-mei=Y. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=13 ORCID= en-aut-name=YoshimiA. en-aut-sei=Yoshimi en-aut-mei=A. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=14 ORCID= en-aut-name=YoshimuraK. en-aut-sei=Yoshimura en-aut-mei=K. kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=15 ORCID= affil-num=1 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=3 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=4 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=5 en-affil=Research Reactor Institute, Kyoto University kn-affil= affil-num=6 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=7 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=8 en-affil=Graduate School of Natural Science and Technology, Okayama University kn-affil= affil-num=9 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=10 en-affil=Research Reactor Institute, Kyoto University kn-affil= affil-num=11 en-affil=Research Institute for Interdisciplinary Science, Okayama University kn-affil= affil-num=12 en-affil=Quantum Metrology Laboratory, RIKEN kn-affil= affil-num=13 en-affil=Japan Synchrotron Radiation Research Institute 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= END start-ver=1.4 cd-journal=joma no-vol=71 cd-vols= no-issue=4 article-no= start-page=301 end-page=307 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=201708 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=A Strategic Protocol to Improve the Process and Outcomes of Two-stage Revision Total Hip Arthroplasty en-subtitle= kn-subtitle= en-abstract= kn-abstract=Two-stage revision total hip arthroplasty (THA) is the most commonly used treatment approach for deep prosthetic infection. However, in this approach the interval between the first and second stage tends to be prolonged. We devised a strategic protocol for improving the infection eradication rate and shortening the interval between the stages in two-stage revision THA. This study analyzed a series of 14 patients (14 hips) from 2008 to 2012, who were treated using an antibiotic-loaded acrylic cement (ALAC) spacer at the first stage and re-implantation at the second stage. The ALAC included vancomycin and amikacin for most of the cases. Patients with MRSA infection were additionally administered intravenous vancomycin in combination with either oral rifampicin or trimethoprim-sulfamethoxazole. The average interval between the stages was 54.2 days overall, and 58.7 days for cases with MRSA infection. Our infection eradication rate was 100%, with no reported recurrence of infection. The presence of MRSA tended to be associated with a longer interval between the two stages. Our protocol for two-stage revision THA was associated with a high eradication rate of infection and a shortened interval between the stages. en-copyright= kn-copyright= en-aut-name=TaniguchiTakaya en-aut-sei=Taniguchi en-aut-mei=Takaya kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=TaniguchiWataru en-aut-sei=Taniguchi en-aut-mei=Wataru kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MiyamotoErabu en-aut-sei=Miyamoto en-aut-mei=Erabu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyazakiNobuyuki en-aut-sei=Miyazaki en-aut-mei=Nobuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=YoshidaMunehito en-aut-sei=Yoshida en-aut-mei=Munehito kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= affil-num=1 en-affil=Department of Orthopaedic Surgery, Wakayama Medical University kn-affil= affil-num=2 en-affil=Department of Orthopaedic Surgery, Wakayama Medical University kn-affil= affil-num=3 en-affil=Department of Orthopaedic Surgery, Wakayama Medical University kn-affil= affil-num=4 en-affil=Department of Orthopaedic Surgery, Wakayama Medical University kn-affil= affil-num=5 en-affil=Department of Orthopaedic Surgery, Wakayama Medical University kn-affil= en-keyword=two-stage revision kn-keyword=two-stage revision en-keyword=infection kn-keyword=infection en-keyword=total hip arthroplasty kn-keyword=total hip arthroplasty en-keyword=antibiotic-loaded acrylic cement, kn-keyword=antibiotic-loaded acrylic cement, en-keyword=methicillinresistant Staphylococcus aureus (MRSA) kn-keyword=methicillinresistant Staphylococcus aureus (MRSA) END start-ver=1.4 cd-journal=joma no-vol=129 cd-vols= no-issue=2 article-no= start-page=81 end-page=83 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170801 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=The 2016 Incentive Award of the Okayama Medical Association in General Medical Science (2016 Yuuki Prize) kn-title=平成28年度岡山医学会賞 総合研究奨励賞(結城賞) en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SakaguchiMasakiyo en-aut-sei=Sakaguchi en-aut-mei=Masakiyo kn-aut-name=阪口政清 kn-aut-sei=阪口 kn-aut-mei=政清 aut-affil-num=1 ORCID= affil-num=1 en-affil=Department of Cell Biolgy, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences kn-affil=岡山大学大学院医歯薬学総合研究科 細胞生物学 END start-ver=1.4 cd-journal=joma no-vol=164 cd-vols= no-issue= article-no= start-page=1 end-page=8 dt-received= dt-revised= dt-accepted= dt-pub-year=2017 dt-pub=20170224 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A Study on the Curriculum of Elementary Schools in Okayama City;

It is produced from cow, mare and camel milk by a traditional method using indigenous starter cultures containing lactic acid bacteria, yeasts and other fermentative microorganisms. Spontaneously fermented milk products have for centuries been consumed for their therapeutic value in promoting health and well-being, especially among the pastoral communities in Mongolia. Most traditional fermentations are conducted as uncontrolled processes, however, increasing research, such as that focused on compositional properties and microbial biota properties, offers prospective views for improving spontaneous fermented products with respect to safety, shelf life, sensory characteristics, and nutritional and functional qualities. The aim of this article is to investigate progress in the microbiological research on the traditional alcoholic fermented milk, airag, in Mongolia and to give an outline of the traditional preparation processes. en-copyright= kn-copyright= en-aut-name=MiyamotoTaku en-aut-sei=Miyamoto en-aut-mei=Taku kn-aut-name=宮本拓 kn-aut-sei=宮本 kn-aut-mei=拓 aut-affil-num=1 ORCID= affil-num=1 en-affil=

Coilを用いて― en-subtitle= kn-subtitle= en-abstract= kn-abstract=Four patients with hemoptysis were treated by bronchial artery embolization, using only stainless steel coils 5mm or 3mm in diameter as the embolic material. Immediate control of hemoptysis was achieved in 3 of the 4 patients without any significant complication. Two of these patients are alive without recurrent hemoptysis, one of them 3 months and the other two years one month after the embolization. One of these patient died of renal failure 5 days after embolization. Recurrent hemoptysis occurred in 1 of the 4 patients with incomplete embolization. A second attempt at embolization failed because the coil fell down through the aorta into the iliac artery. The coil was surgically removed under fluoroscopy. Since the stainless steel coil is a non-absorbable embolic material, if carefully used, longer therapeutic results can be achieved for patients with hemoptysis. en-copyright= kn-copyright= en-aut-name=OhkawaMotoomi en-aut-sei=Ohkawa en-aut-mei=Motoomi kn-aut-name=大川元臣 kn-aut-sei=大川 kn-aut-mei=元臣 aut-affil-num=1 ORCID= en-aut-name=SakamotoKazuhiro en-aut-sei=Sakamoto en-aut-mei=Kazuhiro kn-aut-name=坂本和裕 kn-aut-sei=坂本 kn-aut-mei=和裕 aut-affil-num=2 ORCID= en-aut-name=MiyamotoTsutomu en-aut-sei=Miyamoto en-aut-mei=Tsutomu kn-aut-name=宮本勉 kn-aut-sei=宮本 kn-aut-mei=勉 aut-affil-num=3 ORCID= en-aut-name=MatsunoShinsuke en-aut-sei=Matsuno en-aut-mei=Shinsuke kn-aut-name=松野慎介 kn-aut-sei=松野 kn-aut-mei=慎介 aut-affil-num=4 ORCID= en-aut-name=HosokawaNobuyuki en-aut-sei=Hosokawa en-aut-mei=Nobuyuki kn-aut-name=細川敦之 kn-aut-sei=細川 kn-aut-mei=敦之 aut-affil-num=5 ORCID= en-aut-name=SeoHiroyuki en-aut-sei=Seo en-aut-mei=Hiroyuki kn-aut-name=瀬尾裕之 kn-aut-sei=瀬尾 kn-aut-mei=裕之 aut-affil-num=6 ORCID= en-aut-name=KojimaKanji en-aut-sei=Kojima en-aut-mei=Kanji kn-aut-name=児島完治 kn-aut-sei=児島 kn-aut-mei=完治 aut-affil-num=7 ORCID= en-aut-name=SatohKatashi en-aut-sei=Satoh en-aut-mei=Katashi kn-aut-name=佐藤功 kn-aut-sei=佐藤 kn-aut-mei=功 aut-affil-num=8 ORCID= en-aut-name=KawasakiYukiko en-aut-sei=Kawasaki en-aut-mei=Yukiko kn-aut-name=川崎幸子 kn-aut-sei=川崎 kn-aut-mei=幸子 aut-affil-num=9 ORCID= en-aut-name=TakashimaHitoshi en-aut-sei=Takashima en-aut-mei=Hitoshi kn-aut-name=高島均 kn-aut-sei=高島 kn-aut-mei=均 aut-affil-num=10 ORCID= en-aut-name=TamaiToyosato en-aut-sei=Tamai en-aut-mei=Toyosato kn-aut-name=玉井豊理 kn-aut-sei=玉井 kn-aut-mei=豊理 aut-affil-num=11 ORCID= en-aut-name=TanabeMasatada en-aut-sei=Tanabe en-aut-mei=Masatada kn-aut-name=田邉正忠 kn-aut-sei=田邉 kn-aut-mei=正忠 aut-affil-num=12 ORCID= en-aut-name=NakamuraKenji en-aut-sei=Nakamura en-aut-mei=Kenji kn-aut-name=中村憲二 kn-aut-sei=中村 kn-aut-mei=憲二 aut-affil-num=13 ORCID= affil-num=1 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=2 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=3 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=4 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=5 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=6 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=7 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=8 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=9 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=10 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=11 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=12 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=13 en-affil= kn-affil=香川医科大学第二外科学教室 en-keyword=喀血 kn-keyword=喀血 en-keyword=気管支動脈 kn-keyword=気管支動脈 en-keyword=気管支動脈塞栓術 kn-keyword=気管支動脈塞栓術 en-keyword=Stainless Steel Coil kn-keyword=Stainless Steel Coil END start-ver=1.4 cd-journal=joma no-vol=153 cd-vols= no-issue= article-no= start-page=97 end-page=102 dt-received= dt-revised= dt-accepted= dt-pub-year=2013 dt-pub=20130725 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Sex Difference in Dance Image of Junior High School Students kn-title=中学生のダンスに対するイメージ―男女差の検討― en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SakoHaruko en-aut-sei=Sako en-aut-mei=Haruko kn-aut-name=酒向治子 kn-aut-sei=酒向 kn-aut-mei=治子 aut-affil-num=1 ORCID= en-aut-name=NagataMariko en-aut-sei=Nagata en-aut-mei=Mariko kn-aut-name=永田麻里子 kn-aut-sei=永田 kn-aut-mei=麻里子 aut-affil-num=2 ORCID= en-aut-name=IdeharaChinami en-aut-sei=Idehara en-aut-mei=Chinami kn-aut-name=出原智波 kn-aut-sei=出原 kn-aut-mei=智波 aut-affil-num=3 ORCID= en-aut-name=MiyamotoOtome en-aut-sei=Miyamoto en-aut-mei=Otome kn-aut-name=宮本乙女 kn-aut-sei=宮本 kn-aut-mei=乙女 aut-affil-num=4 ORCID= en-aut-name=IzakiYayoi en-aut-sei=Izaki en-aut-mei=Yayoi kn-aut-name=猪崎弥生 kn-aut-sei=猪崎 kn-aut-mei=弥生 aut-affil-num=5 ORCID= affil-num=1 en-affil= kn-affil= affil-num=2 en-affil= kn-affil= affil-num=3 en-affil= kn-affil= affil-num=4 en-affil= kn-affil= affil-num=5 en-affil= kn-affil= en-keyword=ダンス kn-keyword=ダンス en-keyword=ジェンダー・イメージ kn-keyword=ジェンダー・イメージ en-keyword=ジェンダー・バイアス kn-keyword=ジェンダー・バイアス END start-ver=1.4 cd-journal=joma no-vol=221 cd-vols= no-issue= article-no= start-page=47 end-page=55 dt-received= dt-revised= dt-accepted= dt-pub-year=2012 dt-pub=20120927 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Strong neuroprotection with a novel platinum nanoparticle against ischemic stroke- andtissue plasminogen activator-related brain damages in mice en-subtitle= kn-subtitle= en-abstract= kn-abstract=Reactive oxygen species (ROS) are major exacerbation factor in acute ischemic stroke, and thrombolytic agent tissue plasminogen activator (tPA) may worsen motor function and cerebral infarcts. The platinum nanoparticle (nPt) is a novel ROS scavenger, and thus we examined the clinical and neuroprotective effects of nPt in ischemic mouse brains. Mice were subjected to transient middle cerebral artery occlusion (tMCAO) for 60 min and divided into the following four groups by intravenous administration upon reperfusion, vehicle, tPA, tPA + nPt, and nPt. At 48 h after tMCAO, motor function, infarct volume, immunohistochemical analyses of neurovascular unit (NVU), in vivo imaging of matrix metalloproteinase (MMP), and zymography for MMP-9 activity were examined. Superoxide anion generation at 2 h after tMCAO was also examined with hydroethidine (HEt). As a result, administration of tPA deteriorated the motor function and infarct volume as compared to vehicle. In vivo optical imaging of MMP showed strong fluorescent signals in affected regions of tMCAO groups. Immunohistochemical analyses revealed that tMCAO resulted in a minimal decrease of NAGO and occludin, but a great decrease of collagen IV and a remarkable increase of MMP-9. HEt stain showed increased ROS generation by tMCAO. All these results became pronounced with tPA administration, and were greatly reduced by nPt. The present study demonstrates that nPt treatment ameliorates neurological function and brain damage in acute cerebral infarction with neuroprotective effect on NVU and inactivation of MMP-9. The strong reduction of ROS production by nPt could account for these remarkable neurological and neuroprotective effects against ischemic stroke. en-copyright= kn-copyright= en-aut-name=TakamiyaM.

kn-title=耳下部ヨリ發生シテ頭蓋内竝ニ内耳ニ侵入セル癌腫ノ1症例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Es handelt sich um einem 35 jährigen Bauer, der uns am 27. April 1925 wegen einem seit 2 Monate vorhandenen linksseitigen Halstumor besuchte. Die antiluetische Behandelung und die darauf folgende Radiumapplikation ergaben nicht nur keine Besserung sondern auch bekam or immer heftiger werdende Kopfschmerzen, Schwerhörigkeit, Exopfthalmus, Facialis- und Abduscenslähmung der Linksseite. Am 7. Januar 1926 starb er an der Pneumonie. Er wurde obduciert. Dabei wurde das linken Ohr histologisch untersucht. 1. Sektionsbefund: Ein Plattenepithelkrebs, das aus dem Parotis entwickelte, wuchs nicht bloss an Schädelbasis expansiv, sondern auch ins Schädelinnen durch alle Knochenspalten hinein, wo es sich an dem Hirnbasis verbreitet, wobei es in den inneren Gehörgang auch infiltrierte. 2. Histopathologische Untersuchung des linken Ohres ergab sick wie folgt: a) Im inneren Gehörgang sieht man die Infiltration des Geschwulstgewebes und die spärlichen Vestibularisfasern anstatt des normalen Acusticusstammes. b) Weder Knochenzerstörung noch Erweiterung des inneren Gehörganges ist nachweisbar. c) Der Modiolus ist von Geschwulstzellen infiltriert und Cochlearisfasern fast verschwunden. d) Ganglion vestibulare ist stark verödet und Ganglion spirale ganz verschwunden. e) Die Endapparate des N. acusticus, insbesondere das Cortische Organ, sind, merklich zerstört. Aber kann man dabei Beteiligung der postmortalen Veränderung nicht negieren. f) Die peri- und endolymphatische Raum sind von Geschwulstzellen frei. g) N. facialis und Chorda tympani sind auch degeneriert, und Ganglion geniculi ganz verloren. en-copyright= kn-copyright= en-aut-name=MiyamotoT. en-aut-sei=Miyamoto en-aut-mei=T. kn-aut-name=宮本種美 kn-aut-sei=宮本 kn-aut-mei=種美 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山醫科大學耳鼻咽喉科教室 END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=12 article-no= start-page=3153 end-page=3174 dt-received= dt-revised= dt-accepted= dt-pub-year=1932 dt-pub=19321231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Über die Entwicklung der Magenanlage von Hynobius nigrescens kn-title=Hynobiusニ於ケル胃原基ノ發生ニ就テ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Über die Entwicklung des Amphibienmagens liegen seit langem viele Untersuchungen vor, von denen jedoch die meisten nur die Histogenese und zwar auch nur bei den Anuren behandeln, auf die Morphogenese bei den Urodelen aber nicht näher eingehen. Um diese Lücke in etwa auszufüllen, haben wir in vorliegender Arbeit an der Hand von Serien des Hynobius nigrescens (in Japan einheimischen Urodel) Untersuchungen angestellt. Die hauptsächlichsten Resultate sind wie folgt. 1) Die erste Magenanlage in morphologischer Hinsicht tritt an der Larve von ca. 10mm Gesamtlänge als eine spindelförmige Erweiterung des Vorderdarmes auf, die besonders linksventralwärts gerichtet ist. 2) Dann erweitert sich die Magenanlage immer mehr, besonders linksventralwärts.An der Larve von ca. 14.0mm Gesamtlänge entsteht jetzt der hackenförmigegekrümmte Teil des kaudalen Abschnittes der Magenanlage und auch Magendrüsen und Muskelschicht. 3) Im verlaufe der weiteren Entwicklungsstadien entwickelt sich die Magenanlage in morphologischer und histologischer Hinsicht sehr kräftig. Die Magenanlage ist vollständig linksgelagert, behält aber noch ihre sagittale Anordnung. Die Magenanlage ist äusserlich birnförmig und die Wände derselben besitzen innen viele Falten. An der Larve von 18.0mm Gesamtlänge entscheiden wir deutlich 3 Schichten, (Seröse-, Muskel-, und Epithelschicht). en-copyright= kn-copyright= en-aut-name=MiyamotoYoshita en-aut-sei=Miyamoto en-aut-mei=Yoshita kn-aut-name=宮本義太 kn-aut-sei=宮本 kn-aut-mei=義太 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山醫科大學解剖學教室胎生學研究室 END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=12 article-no= start-page=3144 end-page=3152 dt-received= dt-revised= dt-accepted= dt-pub-year=1932 dt-pub=19321231 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Über den Einfluss von K und Ca auf die Entwicklung der Froschlarven kn-title=K及ビCaノ兩棲類特ニ蛙類ノ蝌蚪ノ發生ニ及ボス影響ニ就テ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Die antagonistische Wirkung von K und Ca auf die verschiedenen Organe der Tiere ist seit langem in pharmakologischer, physiologischer und histologischer Hinsicht bekannt. Deshalb untersuchten wir in embryologischer Hinsicht den Einfluss von K und Ca auf die Entwicklung der Froschlarven. Zugleich tragen wir zur Frage bei betr. der Ernährung der Wassertiere durch Nährstoffe, die im Wasser gelöst sind. Als Material benutzten wir die Larven von Rana esculenta und Bufo vulgaris. Die Tiere wurden etwa 1-2 Woche lang nur mit Wasserplanzen gezüchtet, um beim Beginn der Versuche ihren Ernährungszustand möglichst auszugleichen. Sie wurden auch alle in gleichen physikalischen Bedingungen gehalten. Die folgenden 4 Futterarten wurden verwandt. 1. Hungertiere a) (Leitungswasser aus der Okayama Stadt Wasserleitung).......1000cc b) (Brunnenwasser aus Kamokata, Okayama).......1000cc 2. Calciumtiere (1% Cacl-lösung)........1000cc 3. Kaliumtiere (1% KCl-lösung)........1000cc 4. Kontrolltiere (Wasser aus den larvenhaltigen Stellen).......1000cc Das Wasser wurde täglich gewechselt. Wir fixierten die Larven nach 15, 20 und 30 tägiger Fütterung in Zenkerscher Flüssigkeit um dann Körperlänge, -breite, -gewichte zumessen und die Entwicklungszustände miteinander zu vergleichen. Die Resultate können wir folgendermassen kurz zusammenfassen. Die antagonistische Wirkung von K und Ca auf die Entwicklung der Froschlarven ist nicht sehr auffalend, doch konnte festgestellt werden, dass Ca dieselbe günstiger beeinflusst als K. Die Menge aber von Ca, die für die Entwicklung und Knorpelbildung der Larven nötig ist, ist ganz gering. en-copyright= kn-copyright= en-aut-name=MiyamotoYoshita en-aut-sei=Miyamoto en-aut-mei=Yoshita kn-aut-name=宮本義太 kn-aut-sei=宮本 kn-aut-mei=義太 aut-affil-num=1 ORCID= en-aut-name=TomiokaRyoichi en-aut-sei=Tomioka en-aut-mei=Ryoichi kn-aut-name=富岡諒一 kn-aut-sei=富岡 kn-aut-mei=諒一 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山醫科大學解剖學教室胎生學研究室 affil-num=2 en-affil= kn-affil=岡山醫科大學解剖學教室胎生學研究室 END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=10 article-no= start-page=2678 end-page=2697 dt-received= dt-revised= dt-accepted= dt-pub-year=1932 dt-pub=19321031 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Über die Entstehung des Nervenrohres der Vögel, besonders bei den Embryonen der Columba domestica kn-title=鳥類神經管ノ形成ニ就テ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Der Verfasser stellte über die Bildung des Nervenrohres bei der Columba domestica Untersuchungen an und kam hauptsächlich zu den nachstehenden Resultaten; 1) Man findet schon die Entstehung der Neuralplatte und die Bildung der Neuralrinne durch die beiden Neuralfalten beim Embryo von 3.0mm Grösstlänge mit 2+1? Urwirbeln. 2) Die Neuralfalten nähern sich im kranialen Teil einander und bilden eine ziemlich tiefe Neuralrinne, werden jedoch kaudalwärts flach beim Embryo von 30mm Grösstlänge mit 3-4 Urwirbeln. 3) Die Neuralfalten liegen im Bezirk des Mitterhirns auf eine Strecke von 300 μ fest aneinander an, doch besteht noch kein organischer Zusammenhang, höchstens eine erste Andeutung des Neuralrohres beim Embryo von 3.5mm Grösstlänge mit 4+1? Urwirbeln. 4) Die Bildung des Neuralrohres verlängert sich im kraniokaudaler Richtung des Embryos, und bildet kranial den Neuroporus anterior, kaudalwärts die eigentliche Neuralrinne beim Embryo von 3.0mm Grösstlänge mit 6 Urwirbeln. 5) Das Neuralrohr des Hirnteils bildet das kugelförmige Prosencephalon und die Länge des Neuralrohres wird immer grösser beim Embryo von 3.5mm Grösstlänge mit 7 Urwirbeln. 6) Das Neuralrohr des Hirnteils gliedert sich in das Prosencephalon, Mesencephalon, Rombencephalon und die Augenblase, und die Bildung des Neuralrohr schreitet immer waiter fort beim Embryo von 4.0mm Grösstlänge mit 8 Urwirbeln. 7) Der Neuroporus anterior ist offen, und dahinter ist das Neuralrohr bis zum Ende vollständig geschlossen beim Embryo von 3.3mm Grösstlänge mit 11 Urwirbeln. 8) Der Neuroporus anterior schliesst sich, doch ist seine Stelle noch zu erkennen beim Embryo von 4.0mm Grösstlänge mit 11 Urwirbeln. 9) Der Neuroporus anterior ist vollständig geschlossen, ohne eine Spur zurückzulassen, und die Gliederung des Gehirns ist fast vollendet beim Embryo von 4.5mm Grösstlänge mit 16-17 Urwirbeln. en-copyright= kn-copyright= en-aut-name=MiyamotoYoshita en-aut-sei=Miyamoto en-aut-mei=Yoshita kn-aut-name=宮本義太 kn-aut-sei=宮本 kn-aut-mei=義太 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山醫科大學解剖學教室胎生學研究室 END start-ver=1.4 cd-journal=joma no-vol=44 cd-vols= no-issue=7 article-no= start-page=1961 end-page=1979 dt-received= dt-revised= dt-accepted= dt-pub-year=1932 dt-pub=19320731 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studien über die Entwicklung der Lungenanlage, besonders über die Verästelung des Bronchialbaumes bei Schweineembryonen kn-title=肺臟原基ノ形態學的發生ニ關スル研究哺乳類殊ニ豚胎兒ニ於ケル氣管分枝状況ニ就テ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Embryologische Studien an diesem Tiere, besonders mit Bezug auf die Lunge sind bis jetzt schon von vielen Autoren und von vielen Seiten her eingehend betrieben worden. Neuerdings hat auch Dr. Tani aus unserem Laboratorium eine Arbeit über die erste Entstehungsweise der Lungenanlage veröffentlicht. In dieser publizierten Untersuchung hat er klar bewiesen, dass sich die Lungenanlage zuerst paarig aus der Seitenwand des Vorderdarmes entwickelt. Prof. Shikinami übertrug mir deshalb die Aufgabe, die weiteren Entwicklungsstadien der Lungenanlage, besonders die Verästelungsprozesse der Stammbronchien bei diesem Tiere zuverfolgen. Das Material behandelte ich genau so wie im Falle der Arbeit von Dr. Tani. Die Wachsplattenmodelle wurden in 50, 75 und 100 facher Vergrösserung hergestellt. Als Resultat meiner Untersuchungen möchte ich folgendes hervorheben: 1) Wir finden am Embryo von 4.0 mm (Ursegment 33) grösster Länge zum ersten Mal Trachea und Lungenanlage deutlich wahrnehmbar; Trachealanlage ist vollständig abgesetzt von der Darmkanal- und Lungenanlage. Die linke Lungenanlage verlängert sich nach links horizontal und die rechte Lungenanlage nach rechtskaudalwärts. Und diese ist länger als jene. 2) Im Verlauf der weiteren Entwicklung verlängern sich, wie oben gesagt, beide Lungen, jede in ihrer charakteristischen Richtung und die Winkel der beiden Lungenanlagen in der Ventralansicht werden immer grösser. 3) Ausser der Verlängerung der Trachea und Stammbronchien, entstehen Laterobronchien 1. an den rechten Stammbrochien und ebenso Laterobronchien 2. am Embryo von 10.0 mm Scheitel-Steisslänge. 4) Wir unterscheiden am Embryo von 12.0 mm Nacken-Steisslänge, den ventroinferioren Ast und den dorsoinferioren Ast von den Laterobronchien 1, Laterobronchien 2, 3, 4 Ventrobronchin 2 und mediale Bronchien 4. 5) Ausser dem weiteren Wachstum und den Differenzierungsvorgängen der Laterobronchien 1, 2, 3, 4 und der Ventrobronchien 2, entstehen am Embryo von 17.0 mm Scheitel-Steisslänge die Laterobronchien 5, 6 die Ventrobronchien 3, 4, 5, die dorsale Bnrochien 2 und die mediale Brochien 4, 5. 6) Wir beobachten am Embryo von 20.5 mm Scheitel-Steisslänge immer komplizi-ertere Verästelungszustände des Bronchialbaums. en-copyright= kn-copyright= en-aut-name=MiyamotoYoshita en-aut-sei=Miyamoto en-aut-mei=Yoshita kn-aut-name=宮本義太 kn-aut-sei=宮本 kn-aut-mei=義太 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山醫科大學解剖學教室胎生學研究室 END start-ver=1.4 cd-journal=joma no-vol=45 cd-vols= no-issue=1 article-no= start-page=159 end-page=164 dt-received= dt-revised= dt-accepted= dt-pub-year=1933 dt-pub=19330131 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Über einen Fall von Aneurysma dissecans aortae kn-title=剥離性大動脉瘤ノ1例ニ就テ en-subtitle= kn-subtitle= en-abstract= kn-abstract=Verfasser berichten über einen 53 jährigen Mann, der die klinischen Symptome der Herzlähmung zeigte und bei dem sich bei der Sektion das Aneurysma dissecans feststellen liess. 0.5cm oberhalb der hinteren Semilunarklappe der Aorta findet sich eine querliegende, schmale Risswunde von ca. 2.3-0.2cm, die eine ziemlich abgerundete Ränder besitzt. Die Veränderungen der Aortawand sind sehr bedeutend. Die Intima ist difius oder höckerig verdickt und atheromatös verändert. In der Intima bemerkt man hier und da Rundzelleninfiltration. Die Muskeln und die elastischen Fasern der Media sind degene riert, besonders sind die letzteren gestreckt, oder verschmälert. Man kann in der Media eine fettige Degeneration wahrnehmen. Wir glauben also auf Grund der oben beschriebenen hystologischen Untersuchungen der Aortawand annehmen zu dürfen, dass in diesem Falle atheromatöse Veränderung und Degeneration der elastischen Fasern als wesentliche Factoren bei der Bildung des Aneurysma dissecans die Hauptrolle spielten. en-copyright= kn-copyright= en-aut-name=SatoKan en-aut-sei=Sato en-aut-mei=Kan kn-aut-name=佐藤幹 kn-aut-sei=佐藤 kn-aut-mei=幹 aut-affil-num=1 ORCID= en-aut-name=MiyamotoYoshita en-aut-sei=Miyamoto en-aut-mei=Yoshita kn-aut-name=宮本義太 kn-aut-sei=宮本 kn-aut-mei=義太 aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=岡山醫科大學解剖學教室 affil-num=2 en-affil= kn-affil=岡山醫科大學解剖學教室 END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=9 article-no= start-page=2081 end-page=2101 dt-received= dt-revised= dt-accepted= dt-pub-year=1934 dt-pub=19340930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=On the morphological development of the nerviduct of birds.

Urwirbel, und im kranialen Abschnitte treten die Neuralfalte, Nervenwülste und Neuralrinne auf. 3) Beim Embrya von 3.0mm Grösstlauge mit 5 Urwirbeln nähern sich deutlich die beiden Neuralwülste am Mittelhirn bis die Neuralrinne sich vertieft uud sich U-förmig zeigt und das spätere Nervenrohr anzukündigen. 4) Die beiden Nervenwülste am Mittelhirn berühren sich eine Strecke lang beim Embryo 4.0mm Grosstlänge mit 9 Urwirbeln, und das bedeutet die erste Anlage dee Nervenrohres. 5) Beim Embryo von 4.0mm Grosstlänge mit 10 Urwirbeln verlängert das Nervenrohr kranial wie kaudal und zeigt sich der Neuroporus anterior kranial uud folgt der Neuralrinne kaudal. 6) Beim Embryo mit (10-11?)

The 5/6 renal ablation is an established experimental animal model for glomerular hyperfiltration. On the other hand, low-grade inflammation is also a common mechanism for the progression of kidney diseases including diabetic nephropathy and atherosclerosis. Here we analyzed the gene expression profile in the remnant kidney tissues of 5/6 nephrectomized mice using a DNA microarray system and compared it with that of sham-operated control mice. The 5/6 nephrectomized mice showed glomerular hypertrophy and an increase in the extracellular matrix in the glomeruli. DNA microarray analysis indicated the up-regulated expression of various kinds of genes related to the inflammatory process in remnant kidneys. We confirmed the up-regulated expression of platelet factor-4, and monocyte chemoattractant protein-1, 2, and 5 in remnant kidneys by RT-PCR. The current results suggest that the inflammatory process is involved in the progression of glomerulosclerosis and is a common pathway of the pathogenesis of kidney disease. en-copyright= kn-copyright= en-aut-name=SasakiMotofumi en-aut-sei=Sasaki en-aut-mei=Motofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=ShikataKenichi en-aut-sei=Shikata en-aut-mei=Kenichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=OkadaShinichi en-aut-sei=Okada en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyamotoSatoshi en-aut-sei=Miyamoto en-aut-mei=Satoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=NishishitaShingo en-aut-sei=Nishishita en-aut-mei=Shingo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=Usui KataokaHitomi en-aut-sei=Usui Kataoka en-aut-mei=Hitomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=SatoChikage en-aut-sei=Sato en-aut-mei=Chikage 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= en-aut-name=OgawaDaisuke en-aut-sei=Ogawa en-aut-mei=Daisuke kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=MakinoHirofumi en-aut-sei=Makino en-aut-mei=Hirofumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=2 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=3 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=4 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=5 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=6 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=7 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=8 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=9 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences affil-num=10 en-affil= kn-affil=Department of Medicine and Clinical Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Sciences en-keyword=kidney kn-keyword=kidney en-keyword=inflammation kn-keyword=inflammation en-keyword=chemokine kn-keyword=chemokine END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue= article-no= start-page=39 end-page=51 dt-received= dt-revised= dt-accepted= dt-pub-year=2011 dt-pub=20110201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=エジプト紅海沿岸のマングローブ林の林分構造 kn-title=Forest structure of gray mangrove (Avicennia marina) along Egyptian Red Sea coast en-subtitle= kn-subtitle= en-abstract= kn-abstract=Established mangrove forests along the coastal area of the Arabian Peninsula and African side of the Red Sea are uniquely different from mangrove forests in other parts of the world because of their low biodiversity and harsh habitat of arid and highly saline conditions. Therefore mangrove forests in this area appear in patchy and scattered patterns at mouths of wadi or in sheltered lagoons with rare and irregular flooding. Most of them are pure forests of Avicennia marina, occasionally mixed with Rhizophora mucronata in the southern part of the Red Sea. In this study, we analyze the forest structure of A. marina and discuss the regeneration strategy and the forest dynamics of this unique mangrove species. Three experimental plots of 1000 to 2000 trees/ha were selected from north to south along the Red Sea coast. The highest tree size (6.8m) suggested severe effects of the high salinity of the Red Sea (3.2 to 4.9%) on tree growth. Dense mantle vegetation had developed at the forest edge facing the open sea to protect the forest interior against strong waves and wind. Tree growth was also prevented by severe drought on the landside edge of the forest. All the forests had a dense seedling bank throughout the forest floor, with a very high rate of turnover and regeneration, which seldom occurred in other forests. en-copyright= kn-copyright= en-aut-name=YoshikawaKen en-aut-sei=Yoshikawa en-aut-mei=Ken kn-aut-name=吉川賢 kn-aut-sei=吉川 kn-aut-mei=賢 aut-affil-num=1 ORCID= en-aut-name=InoueMasaki en-aut-sei=Inoue en-aut-mei=Masaki kn-aut-name=井上正樹 kn-aut-sei=井上 kn-aut-mei=正樹 aut-affil-num=2 ORCID= en-aut-name=YoshimoriIchidou en-aut-sei=Yoshimori en-aut-mei=Ichidou kn-aut-name=吉森一道 kn-aut-sei=吉森 kn-aut-mei=一道 aut-affil-num=3 ORCID= en-aut-name=NakashimaAtsushi en-aut-sei=Nakashima en-aut-mei=Atsushi kn-aut-name=中島敦司 kn-aut-sei=中島 kn-aut-mei=敦司 aut-affil-num=4 ORCID= en-aut-name=TeraminamiTomohiro en-aut-sei=Teraminami en-aut-mei=Tomohiro kn-aut-name=寺南智弘 kn-aut-sei=寺南 kn-aut-mei=智弘 aut-affil-num=5 ORCID= en-aut-name=MatsuoNaoko en-aut-sei=Matsuo en-aut-mei=Naoko kn-aut-name=松尾奈緒子 kn-aut-sei=松尾 kn-aut-mei=奈緒子 aut-affil-num=6 ORCID= en-aut-name=BanjoRyo en-aut-sei=Banjo en-aut-mei=Ryo kn-aut-name=萬城遼 kn-aut-sei=萬城 kn-aut-mei=遼 aut-affil-num=7 ORCID= en-aut-name=MiyamotoChiharu en-aut-sei=Miyamoto en-aut-mei=Chiharu kn-aut-name=宮本千晴 kn-aut-sei=宮本 kn-aut-mei=千晴 aut-affil-num=8 ORCID= affil-num=1 en-affil= kn-affil=Graduate School of Environmental Science, Okayama University affil-num=2 en-affil= kn-affil=Faculty of Agriculture, Okayama University affil-num=3 en-affil= kn-affil=Faculty of Agriculture, Okayama University affil-num=4 en-affil= kn-affil=Graduate School of Systems Engineering, Wakayama University affil-num=5 en-affil= kn-affil=Graduate School of Systems Engineering, Wakayama University affil-num=6 en-affil= kn-affil=Graduate School of Bioresources, Mie University affil-num=7 en-affil= kn-affil=Faculty of Bioresources, Mie University affil-num=8 en-affil= kn-affil=NGO, Action for Mangrove Reforestation en-keyword=Gray mangrove (Avicennia marina) kn-keyword=Gray mangrove (Avicennia marina) en-keyword=the Red Sea kn-keyword=the Red Sea en-keyword=forest structure kn-keyword=forest structure en-keyword=seedling bank kn-keyword=seedling bank END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=3-4 article-no= start-page=855 end-page=867 dt-received= dt-revised= dt-accepted= dt-pub-year=1955 dt-pub=19550430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Hearing Test with Speech Sound Part. 3. Hearing Test with Speech Sound of Japanese kn-title=語音による聽力検査に就て 第三編 語音聽力検査法 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In this test, senseless monosyllabic sounds of Japanese speech are used. Generally, 100 sounds are used in one test. As to the test-distance, the point where the difference between normal hearing and slightly impaired hearing begins to be noticed, is determined as standard distance at each test room by each tester. In proportion as the noise of the test room increases, the standard distance is getting shorter. The experiments show that the result of the test is reliable when the standard distance of test room is longer than 1/3 of the standard distance in the sound proof room. The degree of hearing difficulty is expressed in the name of "mis-hearing rate, " which indicates the proportion of the sum of hearing loss and mis-hearing to the tested words' number in percentage. From the results obtained by the above described method, I could classify the patients into 5 categories according to the percentage of hearing loss: normal hearing, less than 5%; very slight difficulty, 5-10%; slight difficulty, 20-30%; moderate difficulty, more than 50%; severe difficulty, 100%. en-copyright= kn-copyright= en-aut-name=MiyamotoM. en-aut-sei=Miyamoto en-aut-mei=M. kn-aut-name=宮本正明 kn-aut-sei=宮本 kn-aut-mei=正明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科教室 END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=3-4 article-no= start-page=849 end-page=853 dt-received= dt-revised= dt-accepted= dt-pub-year=1955 dt-pub=19550430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Hearing Test with Speech Sound Part. 2. Discussion on the Existing Methods of Voice Test kn-title=語音による聽力検査に就て 第二編 従来の所謂言語を以てする聽力検査法に就ての批判 en-subtitle= kn-subtitle= en-abstract= kn-abstract=In the voice tests, meaning words have been used for the long time and the maximum hearing distance is understood to show the degree of hearing. But when meaning words are used, the speech sounds are likely to be understood as words by the help of mental power, even though the hearing is not sufficiently enough to catch the individual speech sounds. Thus, slight impairment of hearing is liable to be overlooked and the results do not mean the true hearing, but the degree of speech understanding. When cautious considerations are brought on the facts that speech sounds are compound sounds, the clearness or intensity of the testers' voice have individual differences, and the architectural acoustics of the test room is not constant, it seems to be impossible to determine the degree of hearing simply by the distances of hearing. By various experiments the author ascertained the following facts: - (1) There is not necessarily any relation which is implied by straight line òr logarithm between the intensity of sound and the distance from the source of sound. These two factors, namely, intensity and distance are variable according to the conditions of test room. (2) Considerable individual differences are seen in the intensity of testers voice. Even when the same person carries on the test, the intensity of sound differs according to the kinds of speech sounds. (3) The maximum distances of hearing for a certain voice differ according to the conditions of the test room. By the above mentioned experiments, it can be pointed out that the exsisting methods of voice test involve various defects. en-copyright= kn-copyright= en-aut-name=MiyamotoM. en-aut-sei=Miyamoto en-aut-mei=M. kn-aut-name=宮本正明 kn-aut-sei=宮本 kn-aut-mei=正明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科教室 END start-ver=1.4 cd-journal=joma no-vol=67 cd-vols= no-issue=3-4 article-no= start-page=843 end-page=848 dt-received= dt-revised= dt-accepted= dt-pub-year=1955 dt-pub=19550430 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Studies on the Hearing Test with Speech Sound Part. 1. On the Relations between Pure Tone Hearing, Speech Sound Hearing and Speech Understanding kn-title=語音による聽力検査に就て 第一編 純音聽力,語音聽力及び言語了解力の関係に就て en-subtitle= kn-subtitle= en-abstract= kn-abstract=We have already recognized the necessity of the hearing test with voice as well as pure tone. Speech hearing is influenced not only by the threshold of pure tone hearing and the character of frequencies, but by the character of vowels and consonants forming the speech sounds, and is not necessarily the same as the pure tone hearing. When meaning words are used in the test, mental power works together with the speech sound hearing, resulting in the test of the speech understanding, and not the determination of the true speech hearing. As the result of tests conducted on many cases of hearing difficulty, it was ascertained that pure tone hearing, speech sound hearing and speech understanding do not come to the equal result, and that there exists no definite relation between the results obtained by the above three tests. en-copyright= kn-copyright= en-aut-name=MiyamotoM. en-aut-sei=Miyamoto en-aut-mei=M. kn-aut-name=宮本正明 kn-aut-sei=宮本 kn-aut-mei=正明 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科教室 END start-ver=1.4 cd-journal=joma no-vol=27 cd-vols= no-issue=3 article-no= start-page=149 end-page=159 dt-received= dt-revised= dt-accepted= dt-pub-year=1995 dt-pub=19951212 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Kenichi Miyamoto: Internationalization of Environmental Policy kn-title=宮本憲一『環境政策の国際化』 (J.JEC環境叢書シリーズ6) 実務出版,1995年 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=SakamotoChuji en-aut-sei=Sakamoto en-aut-mei=Chuji kn-aut-name=坂本忠次 kn-aut-sei=坂本 kn-aut-mei=忠次 aut-affil-num=1 ORCID= affil-num=1 en-affil= 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=2010 dt-pub=20100930 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=モンゴル原産アルコール発酵乳における乳酸菌フローラの分子生物学的解析と機能の応用に関する研究 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MiyamotoMari en-aut-sei=Miyamoto en-aut-mei=Mari kn-aut-name=宮本真理 kn-aut-sei=宮本 kn-aut-mei=真理 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=122 cd-vols= no-issue=3 article-no= start-page=265 end-page=267 dt-received= dt-revised= dt-accepted= dt-pub-year=2010 dt-pub=20101201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Carotid artery stenosis kn-title=頸部頸動脈狭窄症 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OkumaYu en-aut-sei=Okuma en-aut-mei=Yu kn-aut-name=大熊佑 kn-aut-sei=大熊 kn-aut-mei=佑 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 脳神経外科学 END start-ver=1.4 cd-journal=joma no-vol=34 cd-vols= no-issue=1 article-no= start-page=115 end-page=124 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Prime Ideals in Strongly Graded Rings by Polycyclic-by-finite Groups II en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=MarubayashiHidetoshi en-aut-sei=Marubayashi en-aut-mei=Hidetoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoHaruo en-aut-sei=Miyamoto en-aut-mei=Haruo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil= kn-affil=Naruto University affil-num=2 en-affil= kn-affil=Tokushima University END start-ver=1.4 cd-journal=joma no-vol=46 cd-vols= no-issue=5 article-no= start-page=331 end-page=336 dt-received= dt-revised= dt-accepted= dt-pub-year=1992 dt-pub=199210 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Hepatitis C virus antibody titration in patients with chronic hepatitis C, before and after interferon treatment. en-subtitle= kn-subtitle= en-abstract= kn-abstract=

We measured hepatitis C virus antibody titers in 13 patients with chronic hepatitis C to determine whether titration of hepatitis C virus antibody was useful or not, to predict and evaluate the efficacy of interferon (IFN) treatment. During administration of IFN, hepatitis C virus titers declined in all patients. Antibody titers performed before treatment as well as just at the end of treatment did not correlate with change of the alanine aminotransferase levels during administration of IFN. Antibody titers declined continuously after treatment in 5 patients with normal alanine amino-transferase levels for over 6 months after discontinuation of IFN. Antibody titers rose again in 6 patients whose alanine aminotransferase levels fluctuated after treatment. An exceptional pattern of change occurred in 2 patients whose antibody titers declined continuously although their alanine aminotransferase levels fluctuated after treatment. Repeated titration of hepatitis C virus antibody appears to be useful for evaluating the long-term efficacy of IFN treatment.

Rheumatoid arthritis (RA) is often associated with deformities of the feet, and foot pain often arises in the talonavicular joint of patients with RA. The object of this study was to assess the relationship between magnetic resonance imaging (MRI) findings of the talonavicular joint and walking ability. The subjects were 35 RA patients (10 feet in 5 males and 56 feet in 30 females) aged 34-87 years (mean: 70 years +/- 12.1), with a disease duration from 1-54 years (mean: 14 years +/- 12.1). MRI findings were classified as follows: Grade 1, almost normal; Grade 2, early articular destruction; Grade 3, moderate articular destruction; Grade 4, severe articular destruction; and Grade 5, bony ankylosis dislocation. Walking ability was classified into one of 9 categories ranging from normal gait to bedridden status according to the system of Fujibayashi. As the grade of MRI images became higher the walking ability decreased, and these parameters showed a correlation by Spearman's rank correlation coefficient analysis (P = 0.003). Thus, in the present cohort group of patients with RA, the deterioration of walking ability increased with the severity of destruction of the talonavicular joint.

The implication of low affinity nerve growth factor receptor (p75NGFR), which is believed to play a pro-apoptotic role, in delayed neuronal death (DND) after ischemia in the gerbil hippocampus was investigated. Immunohistochemistry and Western blot analysis revealed that the presence of p75 NGFR immunoreactivity (IR) was negligible in the hippocampus of the sham control gerbil but appeared clearly in CA1 neurons 3 and 4 days after 5-min transient ischemia. Terminal deoxynucleotidyl transferase-mediated UTP nick end labeling (TUNEL)

positive nuclei appeared when the level of p75NGFR IR increased. Furthermore, almost all TUNEL-positive CA1 neurons also costained for p75NGFR. These results suggest that p75NGFR contributes to DND after ischemia by an apoptotic mechanism.

Changes in brain vascularity in adult rats during adaptation to chronic normobaric hypoxia with or without elevated CO(2) were morphometrically investigated. Immunohistochemistry with anti-rat endothelial cell antigen (RECA-1) antibody was carried out for the vascular analysis. After the rats were subjected to hypoxia for 2 to 8 weeks (wks)(10 percent O(2) in N(2)), the total area of blood vessels was measured in 6 brain regions. After 2 wks of hypoxia, the blood vessel area was found to be significantly increased in the frontal cortex, striatum, hippocampus, thalamus, cerebellum, and medulla oblongata, by 44% , 96% , 65% , 50% , 102% and 97% , respectively. The ratio of large vessels with an area > 500 micro m(2) was also increased in all brain regions. Hypoxic adaptation in brain vascularity did not change during 8 wks of hypoxia, and the hypoxia-induced levels measured in the vasculature returned to control levels 2 wks after the termination of hypoxia in areas of the brain other than the cortex and thalamus. In addition, hypoxia-induced changes in terms of the total vascular area and vessel size distribution were significantly inhibited by the elevation in CO(2), whereas chronic hypercapnia without hypoxia had no effect on brain vascularity. These findings suggested that adaptations in brain vascularity in response to hypoxia are rapidly induced, and there are regional differences in the reversibility of such vascular changes. Carbon dioxide is a potent suppressor of hypoxia-induced vascular changes, and may play an important role in vascular remodeling during the process of adaptation to chronic hypoxia.

Macrophages and microglia are implicated in spinal cord injury, but their precise role is not clear. In the present study, activation of these cells was examined in a spinal cord injury model using 2 different antibodies against ED1 clone and ionized calcium binding adaptor molecule 1 (Iba1). Activation was observed at 1, 4, 8, and 12 weeks after contusion injury and was compared with sham operated controls. Our results indicate that activation could be observed in both the dorsal funiculus and the ventral white matter area in the spinal cord at 5 mm rostral to the epicenter of injury. For both cells, there was a gradual increase in activation from 1-4 weeks, followed by down-regulation for up to 12 weeks. As a result, we could stain macrophages by ED1 and microglia by Iba1. We concluded that macrophages may play a role in the phagocytosis of denatured dendrites after spinal cord injury, while microglia may have some cooperative functions, as they were found scattered near the macrophages.

An adriamycin (ADM)-resistant subline was established by continuous exposure of the SBC-3 cells, a cell line of human small cell lung cancer, to increasing concentrations of ADM, followed by the cloning procedure. The resistant sublines (SBC-3/ADM) thus established were 30-fold more resistant to ADM than the parent SBC-3 cells, in terms of the 70% lethal dose determined by soft agar clonogenic assay. The doubling times of the SBC-3 and SBC-3/ADM cells were 36 h and 22 h, respectively. When transplanted into athymic nude mice, the parent as well as resistant cells formed tumors, and serial passage was successful. Although the transplanted tumors from the two cell lines were very similar in histology, the resistance of the SBC-3/ADM cells to ADM developed in vitro was maintained in serially transplanted tumors. The uptake studies with [3H]daunomycin revealed decreased influx and enhanced active efflux of the drug in the resistant cells, whereas cytogenetic analysis showed that the cell lines had an identical karyotype. These results indicate that ADM resistance may be attributed to alternations in membrane transport, resulting in reduced intracellular accumulation of the drug.

Using a cell line (SBC-3/ADM) of human small cell lung cancer, which is 30-fold more resistant to adriamycin than the parent cell line (SBC-3), the activity of a variety of anticancer agents was analyzed by soft agar clonogenic assay to search for a means of circumventing drug resistance. The SBC-3/ADM cells were markedly resistant to some anthracycline antibiotics in comparison with the SBC-3 cells: 28-fold for daunomycin, 26-fold for 4'-epiadriamycin, 18-fold for THP-adriamycin, and 8.4-fold for aclarubicin. However, the cells were as sensitive to mitoxantrone, one of the anthraquinone derivatives, as the parent cells. The cells were resistant to structurally or pharmacodynamically unrelated compounds such as vincristine, mitomycin C, and an active form of ifosfamide, whereas they were susceptible to cisplatin to some extent. The in vitro radiosensitivity of both cell lines was also evaluated, and they were found to be equally sensitive to X-ray. These results suggest that mitoxantrone and cisplatin may exert sufficient activity for small cell lung cancer which has acquired resistance to adriamycin, and that consolidative chest irradiation may be clinically useful after combination chemotherapy including adriamycin.

Basic fibroblast growth factor (bFGF) and nerve growth factor (NGF) were administered into the rat brain following unilateral fimbria-fornix transection. Both bFGF and NGF stimulated the sprouting of acetylcholinesterase (AChE) positive fibers in the hippocampus on the lesioned side. Furthermore, a small number of AChE-positive fibers were regenerated even when only the vehicle was administered. Rats treated with NGF as well as control group had only thin fibers, whereas those treated with bFGF had not only thin fibers but also thick fibers. These results indicate that intrinsic NGF is released and acts on damaged neurons directly, while bFGF acts them on directly and/or indirectly after brain injury.

Partial excess of chromosome 1 (q25-q32) was noted in malignant cells from all of 10 patients who had disorders such as non-African Burkitt's lymphoma, adult T-cell leukemia, myelofibrosis, malignant lymphoma, chronic lymphocytic leukemia or chronic myelocytic leukemia in blast crisis. The break points on chromosome 1 were at centromere, q12, q21, q23, q25 and q32. Variations in the specific region of the long arm of chromosome 1, q25-q32, were thought to be important in the evolution of malignant cell proliferation.

Hepatitis C virus (HCV)-RNA in the blood was measured by polymerase chain reaction (PCR) in 37 subjects from eight families in which 2 or more persons tested seropositive for antibodies against C100-3 or CP9. HCV-RNA was positive in 17 of 37 subjects. Two or more HCV-RNA-positive subjects were observed in six of the families. Intrafamilial HCV infection was studied by determining the HCV-RNA type (I, II, III or IV) by PCR using type-specific primers. In two families, all of the subjects showed type III infection, and in three other families, all of the subjects showed type II infection, with different types of HCV infections being observed in only one family. The HCV type was uniform in all but one. These findings suggest a possibility of intrafamilial infection between husbands and wives and between members of the same household.

The rearrangement of breakpoint cluster region (ber) was examined in leukemic cells obtained from 3 patients initially diagnosed as having Ph+ acute leukemia, 2 with acute lymphocytic leukemia (ALL) and one with acute mixed leukemia. DNA was digested with Bgl II and BamH I. The ber rearrangement was present in the case of acute mixed leukemia (Case 1), but was absent in the 2 cases of ALL (Cases 2 and 3). These results suggest that Case 1 represented a type of blast crisis of chronic myelocytic leukemia which was unusual in the sense of the occurrence of a myeloid-lymphoid conversion and lack of an apparent chronic phase. Cases 2 and 3 appeared to be de novo Ph+ ALL.

An eleventh case of heavy (Hgamma1) chain disease (Yok), surviving for more than 10 years and still living showed clinical and pathological findings similar to cases described in the past. The patient was given only glucocorticosteroids, ACTH, antibiotics and gamma globulin, as specific drugs. Precipitation arcs besides the major ones formed by albumin and Fc fragment were disclosed by immunoelectrophoresis. The existence of these minor components were confirmed with antigen-antibody crossed electrophoresis and Sephadex G-200 gel filtration. They did not form precipitation arcs with the other antigens available and they appeared in the same fractions of IgG on gel filtration suggesting their having higher molecular weight than the major ones. In addition to these findings, the clinical course of the patient is described.

In vitro quantitative biosynthetic studies were carried out on bone marrow cells obtained from an eleventh case with gamma heavy chain disease. The findings indicate that neither cytoplasmic nor extracellular degradation was responsible for the presence of the gamma heavy chain fragment in serum. The absence of a covalent-bound light chain was also confirmed.

An abnormal protein with similar antigenic properties to Fc fragments of IgG, was found in the serum and urine of an eleventh case of heavy (Hgamma1) chain disease (Yok). This protein was purified with ammonium sulfate precipitation and by column chromatography of DEAE cellulose, CM cellulose and Sephadex G-200. The purity of the protein obtained was 98.5%. It was crystallized easily, forming thin hexagonal plates of various sizes. The chemical compositions and physical properties of the protein including viscosity, partial specific volume, diffusion constant, sedimentation constant, frictional ratio, extinction coefficient and iso-ionic point are reported.

We examined whether lesions in the prefrontal cortex (PFC) could modify the rotational behavior in PD model rats. Rats initially received unilateral lesions of the substantia nigra by 6-OHDA injection, and then their rotational behavior was measured. Two PFC lesions were achieved by intracerebral infusions of ibotenic acid, followed by measurement of APOinduced rotation. Rotation was reduced by approximately 30オ after PFC injury. The PFC may have functional infl uences on the basal ganglia and may be involved in the pathophysiology of the rotational behavior of PD model rats. en-copyright= kn-copyright= en-aut-name=GonzalezDaniel en-aut-sei=Gonzalez en-aut-mei=Daniel kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyamotoOsamu en-aut-sei=Miyamoto en-aut-mei=Osamu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=TougeTetsuo en-aut-sei=Touge en-aut-mei=Tetsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=SumitaniKazunori en-aut-sei=Sumitani en-aut-mei=Kazunori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=KuriyamaShigeki en-aut-sei=Kuriyama en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=ItanoToshifumi en-aut-sei=Itano en-aut-mei=Toshifumi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=Kagawa University, Kagawa affil-num=2 en-affil= kn-affil=Kagawa University, Kagawa affil-num=3 en-affil= kn-affil=Kagawa University, Kagawa affil-num=4 en-affil= kn-affil=Kagawa University, Kagawa affil-num=5 en-affil= kn-affil=Kagawa University, Kagawa affil-num=6 en-affil= kn-affil=Kagawa University, Kagawa en-keyword=Parkinson model rat kn-keyword=Parkinson model rat en-keyword=rotational behavior kn-keyword=rotational behavior en-keyword=ibotenic acid kn-keyword=ibotenic acid en-keyword=6-hydroxydopamine kn-keyword=6-hydroxydopamine en-keyword=prefrontal cortex kn-keyword=prefrontal cortex END start-ver=1.4 cd-journal=joma no-vol=36 cd-vols= no-issue=2 article-no= start-page=157 end-page=160 dt-received= dt-revised= dt-accepted= dt-pub-year=1982 dt-pub=198204 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Chromosome 8-14 translocation in a non-African Burkitt's lymphoma with leukemic conversion. en-subtitle= kn-subtitle= en-abstract= kn-abstract=

A specific chromosome translocation, t(8q-; 14q+), was observed in a 43-year-old female with non-African Burkitt's lymphoma in which leukemic conversion had occurred. The chromosome studies used cells from ascites. The ascites was apparently the result of a primary tumor involving the ovaries and contained 68% of lymphoma cells. The frequent occurrence of abnormalities related to chromosomes 1, 8 and 14 in African and non-African Burkitt's lymphomas was emphasized.

Cytogenetic studies were performed on a biopsy specimen of a jaw tumor and on a bone marrow aspirate from a Japanese patient with Epstein-Barr virus-negative Burkitt's lymphoma. A 14q + chromosome was found in cells from either source, although each contained a different clone. Other karyotypic abnormalities present in common included 2dir dup (1q) (q21 leads to q32), 3q+, 6p--, +12, +mar.

Chromosome analysis was performed on cells obtained from the pleural effusion of a Japanese patient with Burkitt's lymphoma. Two modal chromosomal numbers were found: 45 and 46. Five different karyotypes were present, all having a t (8q-;14q+) translocation. This case illustrates that Burkitt's lymphomas of Japanese are no exception to the frequent association of this chromosomal abnormality with Burkitt's lymphomas.

Analysis of the chromosomes of a cloned human hepato-blastoma cell line, HUH-6-clone 5 by Q-, G- and C-banding revealed numerical and structural chromosome aberrations. The modal number of chromosomes was 49. Trisomies #12 and 20 were present in most of the cells, and 8q isochromosome was detected in all of the cells analyzed. High levels of alpha-fetoprotein production by this cell strain were also demonstrated.

Fifty patients with chronic myelocytic leukemia (CML) grouped into four stages on the basis of clinical and hematological results were analyzed with chromosomal banding techniques. Of the 50 patients, 48 hand the "standard" type of Ph1 translocation, t(9 ; 22) (q34 ; q11) and the remaining 2 had Ph1-negative diploid karyotype. The frequency of numerical chromosomal changes and/or structural chromosomal changes other than the Ph1 translocation varied with the stages; the frequency was 1 of 28 cases (3.6%) for patients in stage I (chronic phase), 5 of 11 (45.5%) in stage II (early stage of blastic phase), 11 of 13 (84.6%) in stage III (blastic phase) and 2 of 7 (28.6%) in stage IV (remission phase). Numerical changes in hyperdiploid leukemic cells correlated well with the appearance of extra #8 and extra Ph1 In 5 cases with hypodiploid leukemic cells, one of the #7 pair was absent in 4 cases and Y in 1 case. As structural changes, partial excess of chromosome 1, isochromosome 17q, isochromosome 1q, tdic (20p+ ; 21q-), del (7) (q11), t(2p+ ; 11p-), #12q+ and Xp+ were observed. Chromosomal analysis alone is not the best marker to diagnose the onset of blastic phase; however, it is a useful parameter when considered in combination with clinical and hematological results.

A rare case of variant Philadelphia (Ph1) chromosome positive [46, XX, t (9; 22) (q34; q11), inv (9) (9q22; 22q13)] chronic myelocytic leukemia (CML) was described. The patient, 73 years old female, was hospitalized to our hospital because of leukocytosis. Hematological findings corresponded to those of CMLs. However, this case lacked hepatosplenomegaly. Southern blot analysis using a 3 breakpoint cluster region (bcr) probe revealed a bcr rearrangement. The patient has been in the chronic phase for sixteen months without treatment. Clinical and chromosomal changes are under observation in order to get accumulate data for a pathophysiological analysis of variant Ph1 positive CMLs.

An enzyme-linked immunosorbent assay (ELISA) using biotin-labelled oligo-dT primer and digoxigenin (Dig)-dUTP was designed to measure the reverse transcriptase (RT) activity of human immunodeficiency virus type 1 (HIV-1). The ELISA system involves the selective detection step of a newly synthesized cDNA by two specific bindings, biotin-streptavidin binding and alkaline phosphatase (AP)-conjugated anti-Dig-Dig binding, and the enzymatic amplification step to increase coloring generated by AP. This method was used to measure the activity of RT in the culture supernatants of peripheral leukocytes obtained from four anti-HIV-1-positive persons cocultivated with those from four anti-HIV-1-negative persons. RT activity was detected in all of four anti-HIV-1-positive culture supernatants but not in those cultivated with anti-HIV-1-negative supernatants alone. Thus, our improved ELISA for detection of HIV-1 appears to be sensitive enough and useful for routine laboratory work. This non-radioactive method will also be useful for detecting other retroviruses and for screening of RT inhibitors.

As there is no report other than that by Miyamoto concerning the relationship between blood of the acatalasemic patient and bacteria and considering this to be an interesting problem, the author conducted a series of experiments with a view to elucidate actions of several bacteria belonging to Streptococcus and Pneumococcus on blood of the acatalasemic patients. Namely, the author carried out aerobic and anaerobic cultures with the medium containing Diprococcus pneumoniae Ⅰ, Ⅱ, Ⅲ, Streptococcus hemolyticus, or Streptococcus viridans, which was loaded with either acatalasemic blood or blood of the normal person, and other series of cultures containing each of the these media loaded still further by inoculation of other medium containing either KCN or hydroxylamine (inhibitory agent of catalase action). By macroscopic and spectroscopic observation on the results of above mentioned expeirments, the following findings were obtained. 1) As regards the rate of bacterial growth under either condition no great difference could be recognized between the medium loaded with normal blood and that with acatalasemic blood. 2) In the cases of aerobic culture, the production of Methb and decolorization in the media containing actalasemic blood tended to be more marked than those in the media with normal blood. 3) In the cases of anaerobic culture, the production of MetHb and decolorization phenomenon decreased in the media containing acatalasemic blood. 4) In the aerobic culture with the medium loaded with inhibitory agent of catalase action, the rate of MetHb production and decolorization phenomenon were about the same in both the medium with normal blood and the medium with patient's blood. While, in anaerobic cultures influences of addition of these agents could hardly be discerned. 5) Since the blood of patient doss not contain catalase, the production of MetHb and decolorization phenomenon in the medium containing acatalasemic blood seem to have occured due to influences of hydrogen peroxide (H(2)O(2)) produced by bacteria. en-copyright= kn-copyright= en-aut-name=KawataMikitaro en-aut-sei=Kawata en-aut-mei=Mikitaro kn-aut-name=河田幹太郎 kn-aut-sei=河田 kn-aut-mei=幹太郎 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学医学部耳鼻咽喉科教室 END start-ver=1.4 cd-journal=joma no-vol=84 cd-vols= no-issue=9-10 article-no= start-page=247 end-page=266 dt-received= dt-revised= dt-accepted= dt-pub-year=1972 dt-pub=19721030 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Thalamo-cortical Relationship in Evoked Cortical Responses Following Human Ventrolateral Thalamic Stimulation kn-title=Thalamo-cortical Relationに関する電気生理学的研究-ヒト視床腹外側核刺激による皮質誘発反応の分析- en-subtitle= kn-subtitle= en-abstract= kn-abstract=Electrophysiological studies on evoked cortical potentials following ventrolateral (VL) thalamic stimulation of man were performed with averaging computer technique for 41 patients of parkinsonism and other involuntary movement disorders during stereotaxic surgery for last 2 years. 1. Single stimulation of the VL nucleus demonstrated bilateral cortical activity with I-PN (first positive negative), Ⅱ-PN (second positive negative), Ⅲ-PN (third positive negative) and Ⅳ-PN (fourth positive negative) waves. Ⅲ-P wave was frequently superimposed on negative response between Ⅱ-N and Ⅲ-N wave, and Ⅳ-PN waves were frequently feeble in single stimulation of the VL nucleus. 2. Peak latencies of these waves were estimated 3.4±1.2 msec in Ⅰ-P, 10.6±1.8 msec in Ⅰ-N, 29±5 msec in Ⅱ-P, 55±6 msec in Ⅱ-N, 71±11 msec in Ⅲ-P, 90±11 msec in Ⅲ-N, 115±19 msec in Ⅳ-P and 160±24 msec in Ⅳ-N wave in ipsilateral central lead, and 4.0±1.5 msec in Ⅰ-P, 11.1±2.1 msec in Ⅰ-N, 31±4 msec in Ⅱ-P, 57±6 msec in Ⅱ-N, 74±13 msec in Ⅲ-P, 92±12 msec in Ⅲ-N, 118±24 msec in Ⅳ-P and 156±29 msec in Ⅳ-N wave in contralateral central lead. 3. The first deflection time of Ⅰ-P wave, which meant beginning of the evoked response, was 1.5-1.8 msec in stimulated side of central cortex and 2.2-2.9 msec in contralateral central lead, which were obtained in 5 cases precisely measured. 4. The impulse, which provoked Ⅰ-P N waves, was thought to be conducted from stimulated VL nucleus to the contralateral cortex directly via corpus callosum with 36-43m/sec of velocity. 5. Cortical evoked responses following suprathreshold low frequency stimulation (5-12Hz) of the VL nucleus showed invariably augmenting response and recruiting-like augmenting response. Augmenting response, which consisted of a train of growth in both. positive and negative components, was evoked when each stimulus was given on the descending phase from the peak of Ⅲ-N or augmented negativiy to the bottom of following positive wave of the preceding response. Analysis of augmentation suggested that synchronization of preceding evoked Ⅳ-P and present Ⅱ-P wave would be occured in augmented positivity and synchronization of preceding evoked Ⅳ-N and present Ⅱ-N or Ⅲ-N wave would be occured in augmented negativity. Recruiting-like augmenting response was obtained when each stimulus was given on the ascending phase from the bottom of deep Ⅳ-P to the following negative wave of the preceding response. Recruiting-like augmentation was shown to be a similar response as augmenting response in the fundamental pattern of averaged evoked activity, although development of negativity and attenuation of positivity caused recruiting-like pattern. Component analysis of recruiting-like augmenting response revealed that predominant development of negativity was thought to be the result of the synchronization of preceding evoked Ⅳ-N and present Ⅱ-N or Ⅲ-N wave. And attenuation of Ⅱ-P wave was thought to be the result of the desynchronization of preceding Ⅳ-N and present Ⅱ-P wave. Responses following lower frequency stimulation with 4Hz or less were similar to responses following single stimulation. Subthreshold stimulation were thought to be difficult to induce any growth of negative cortical response. 6. It was clarified that cortical evoked response following stimulation of the VL nucleus was influenced by components and phases of the preceding cortical response, suggesting that human specific thalamic system would play a possible important role in modulation upon cortical electrical activity. en-copyright= kn-copyright= en-aut-name=MiyamotoToshihiko en-aut-sei=Miyamoto en-aut-mei=Toshihiko kn-aut-name=宮本俊彦 kn-aut-sei=宮本 kn-aut-mei=俊彦 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学脳神経外科学教室 END start-ver=1.4 cd-journal=joma no-vol=85 cd-vols= no-issue=7-8 article-no= start-page=373 end-page=385 dt-received= dt-revised= dt-accepted= dt-pub-year=1973 dt-pub=19730830 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Mechanism of Cortical Synchronized Activities with Special Reference to the Ventrolateral Thalamic Nucleus kn-title=大脳皮質電気活動の同期化における視床腹外側核の関与について-ヒトとネコにおける電気生理学的研究- en-subtitle= kn-subtitle= en-abstract= kn-abstract=Spindle-like afterdischarges evoked by stimulation of ventrolateral thalamic nucleus and spontaneous spindle waves were analized to investigate the electrophysiological mechanism of cortical synchronized activities in man as well as in cat. In man, three positive and three negative waves, namely Ⅰ-P, Ⅰ-N, Ⅱ-P, Ⅱ-N, Ⅲ-P and Ⅲ-N, were observed as cortical evoked responses after single stimulation of the ventrolateral thalamic nucleus. And Ⅳ-P and Ⅳ-N were observed after the stronger stimulation which could provoke augmenting response with the repetitive volley. Later components of evoked cortical responses were investigated in cat immobilized under local anesthasia. Recording electrole was located on the anterior sigmoid gyrus. As the intensity of the thalamic stimulation was increased, afterdischarges of the negative waves, which appeared with long latency (about 200 msec.), increased in number and developed into spindle-like pattern with notches on afterdischarges. The long latencied negative wave in cat and Ⅳ-N in man were considered to correspond to Lehtinen's "precursor of the evoked spindle activity". It has been already reported by Miyamoto that Ⅳ-N was supposed to play an important role in augmenting response in man. Close relationship was indicated between augmenting response and spindle-like afterdischarges. Futhermore, the similarities of the pattern between spindle-like afterdischarges following thalamic stimulation and spontaneous spindle waves in cat, and attenuation of ipsilateral spontaneous spindle waves after destruction of the ventrolateral thalamic nucleus in cat as well as in man were also observed. From these facts these cortical synchronized activities, namely AR, spindle-like afterdischarges and spontaneous spindle waves were considered to be brought by similar neuronal mechanism with some varieties of synchronization ascribed to arousal levels under influences of activities of the ventrolateral thalamic nucleus. On the other hand, spindle-like afterdischarges and spontaneous spindle waves in cat were analized for investigating their waxing and waning phenomena. Notches were observed on each waves. When the wave grew with maximal amplilude in a train of spindle, the notch of the wave became obscure. The phenomenon was considered that the notch was synchronized with the wave, forming maximal amplilude of the wave in a train of spindle. In other words, mechanism of this phenomenon was supposed to be explained as a beat of two rhythmic activities slightly different in frequency. en-copyright= kn-copyright= en-aut-name=BeckHiroichi en-aut-sei=Beck en-aut-mei=Hiroichi kn-aut-name=別宮博一 kn-aut-sei=別宮 kn-aut-mei=博一 aut-affil-num=1 ORCID= affil-num=1 en-affil= kn-affil=岡山大学脳神経外科教室 END start-ver=1.4 cd-journal=joma no-vol=121 cd-vols= no-issue=3 article-no= start-page=149 end-page=156 dt-received= dt-revised= dt-accepted= dt-pub-year=2009 dt-pub=20091201 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=A CACNB4 mutation showing altered Ca(v)2.1 function in a patient with Dravet syndrome kn-title=Dravet 症候群患者に認められたカルシウムチャネル 機能異常を引き起こす CACNB4 遺伝子変異 en-subtitle= kn-subtitle= en-abstract= kn-abstract= en-copyright= kn-copyright= en-aut-name=OhmoriIori en-aut-sei=Ohmori en-aut-mei=Iori kn-aut-name=大守伊織 kn-aut-sei=大守 kn-aut-mei=伊織 aut-affil-num=1 ORCID= en-aut-name=OuchidaMamoru en-aut-sei=Ouchida en-aut-mei=Mamoru kn-aut-name=大内田守 kn-aut-sei=大内田 kn-aut-mei=守 aut-affil-num=2 ORCID= en-aut-name=MimakiNobuyoshi en-aut-sei=Mimaki en-aut-mei=Nobuyoshi kn-aut-name=御牧信義 kn-aut-sei=御牧 kn-aut-mei=信義 aut-affil-num=3 ORCID= en-aut-name=NishikiTeiichi en-aut-sei=Nishiki en-aut-mei=Teiichi kn-aut-name=西木禎一 kn-aut-sei=西木 kn-aut-mei=禎一 aut-affil-num=4 ORCID= en-aut-name=TomizawaKazuhito en-aut-sei=Tomizawa en-aut-mei=Kazuhito kn-aut-name=富澤一仁 kn-aut-sei=富澤 kn-aut-mei=一仁 aut-affil-num=5 ORCID= en-aut-name=MatsuiHideki en-aut-sei=Matsui en-aut-mei=Hideki kn-aut-name=松井秀樹 kn-aut-sei=松井 kn-aut-mei=秀樹 aut-affil-num=6 ORCID= affil-num=1 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 細胞生理学 affil-num=2 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 分子遺伝学 affil-num=3 en-affil= kn-affil=倉敷成人病センター 小児科 affil-num=4 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 細胞生理学 affil-num=5 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 細胞生理学 affil-num=6 en-affil= kn-affil=岡山大学大学院医歯薬学総合研究科 細胞生理学 en-keyword=てんかん kn-keyword=てんかん en-keyword=Dravet 症候群 kn-keyword=Dravet 症候群 en-keyword=CACNB4遺伝子 kn-keyword=CACNB4遺伝子 en-keyword=SCN1A 遺伝子 kn-keyword=SCN1A 遺伝子 END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=11-12 article-no= start-page=1155 end-page=1160 dt-received= dt-revised= dt-accepted= dt-pub-year=1988 dt-pub=1988 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Clinical survey of the adverse reaction to a new low osmolality contrast medium (ioxaglate) kn-title=低浸透圧性ヨード造影剤Ioxaglate(Hexabrix®)の使用経験―その副作用調査を中心に― en-subtitle= kn-subtitle= en-abstract= kn-abstract=A clinical survey on the adverse reaction to a new low osmolality contrast medium (ioxaglate) was performed in 83 patients during June-October 1987. These patients were followed up for 24 hours following angiographic examination. The incidence of adverse reactions due to ioxaglate was 8.4%(7/83). There were no severe reactions, but we encountered nausea, rash and others. The incidence of vascular pain was 6.0%(5/83), we excluded vascular pain from this data because of the difficulty of objectively evaluating vascular pain. The incidence of adverse reactions excluding vascular pain, in our survey, was lower than that (38.8%) reported by Katayama et al.6), because of the low osmolality of ioxaglate. Adverse reations were encountered in 4 of 7 patients after leaving the examination room. Panto et al.8) reported that there were some delayed adverse reactions to contrast media. We propose that clinical surveys of adverse reactions should be discussed in consideration of data obtained after the patient leaves the examination room. en-copyright= kn-copyright= en-aut-name=MiyamotoTsutomu en-aut-sei=Miyamoto en-aut-mei=Tsutomu kn-aut-name=宮本勉 kn-aut-sei=宮本 kn-aut-mei=勉 aut-affil-num=1 ORCID= en-aut-name=KojimaKanji en-aut-sei=Kojima en-aut-mei=Kanji kn-aut-name=児島完治 kn-aut-sei=児島 kn-aut-mei=完治 aut-affil-num=2 ORCID= en-aut-name=OhkawaMotoomi en-aut-sei=Ohkawa en-aut-mei=Motoomi kn-aut-name=大川元臣 kn-aut-sei=大川 kn-aut-mei=元臣 aut-affil-num=3 ORCID= en-aut-name=SeoHiroyuki en-aut-sei=Seo en-aut-mei=Hiroyuki kn-aut-name=瀬尾裕之 kn-aut-sei=瀬尾 kn-aut-mei=裕之 aut-affil-num=4 ORCID= en-aut-name=ToyamaYoshihiro en-aut-sei=Toyama en-aut-mei=Yoshihiro kn-aut-name=外山芳弘 kn-aut-sei=外山 kn-aut-mei=芳弘 aut-affil-num=5 ORCID= en-aut-name=KageyamaJunichi en-aut-sei=Kageyama en-aut-mei=Junichi kn-aut-name=影山淳一 kn-aut-sei=影山 kn-aut-mei=淳一 aut-affil-num=6 ORCID= en-aut-name=TsuuchiYasuhiko en-aut-sei=Tsuuchi en-aut-mei=Yasuhiko kn-aut-name=津内保彦 kn-aut-sei=津内 kn-aut-mei=保彦 aut-affil-num=7 ORCID= en-aut-name=MoriYasutane en-aut-sei=Mori en-aut-mei=Yasutane kn-aut-name=森泰胤 kn-aut-sei=森 kn-aut-mei=泰胤 aut-affil-num=8 ORCID= en-aut-name=TanabeMasatada en-aut-sei=Tanabe en-aut-mei=Masatada kn-aut-name=田邉正忠 kn-aut-sei=田邉 kn-aut-mei=正忠 aut-affil-num=9 ORCID= en-aut-name=HinoIchiroh en-aut-sei=Hino en-aut-mei=Ichiroh kn-aut-name=日野一郎 kn-aut-sei=日野 kn-aut-mei=一郎 aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=2 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=3 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=4 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=5 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=6 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=7 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=8 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=9 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=10 en-affil= kn-affil=住友別子病院放射線科 en-keyword=低浸透圧造影剤 Ioxaglate kn-keyword=低浸透圧造影剤 Ioxaglate en-keyword=副作用調査 kn-keyword=副作用調査 END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=11-12 article-no= start-page=1149 end-page=1154 dt-received= dt-revised= dt-accepted= dt-pub-year=1988 dt-pub=1988 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Differential diagnosis between a case of AVM and a case of cerebral infarction by IMP SPECT kn-title=(123)I-IMP脳SPECTにて鑑別可能であったAVMと脳梗塞の2例 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Two patients who were suspected of having arteriovenous malformation(AVM) by plain and contrast enhancement cranial CT were examined by brain SPECT with I-123-IMP.

The other was diagnosed as cerebral infarction with luxury perfusion, based on the finding of hyperperfusion on two images. The final diagnoses of these two patients were confirmed by angiography and/or operation. We considered brain SPECT with I-123-IMP to be very useful for the differentiation between AVM and cerebral infarction with luxury perfusion, which was suspected of being AVM by cranial contrast enhancement CT. en-copyright= kn-copyright= en-aut-name=MiyamotoTsutomu en-aut-sei=Miyamoto en-aut-mei=Tsutomu kn-aut-name=宮本勉 kn-aut-sei=宮本 kn-aut-mei=勉 aut-affil-num=1 ORCID= en-aut-name=KawasakiYukiko en-aut-sei=Kawasaki en-aut-mei=Yukiko kn-aut-name=川崎幸子 kn-aut-sei=川崎 kn-aut-mei=幸子 aut-affil-num=2 ORCID= en-aut-name=SatohKatashi en-aut-sei=Satoh en-aut-mei=Katashi kn-aut-name=佐藤功 kn-aut-sei=佐藤 kn-aut-mei=功 aut-affil-num=3 ORCID= en-aut-name=TamaiToyosato en-aut-sei=Tamai en-aut-mei=Toyosato kn-aut-name=玉井豊理 kn-aut-sei=玉井 kn-aut-mei=豊理 aut-affil-num=4 ORCID= en-aut-name=TakashimaHitoshi en-aut-sei=Takashima en-aut-mei=Hitoshi kn-aut-name=高島均 kn-aut-sei=高島 kn-aut-mei=均 aut-affil-num=5 ORCID= en-aut-name=OhkawaMotoomi en-aut-sei=Ohkawa en-aut-mei=Motoomi kn-aut-name=大川元臣 kn-aut-sei=大川 kn-aut-mei=元臣 aut-affil-num=6 ORCID= en-aut-name=YodenMidori en-aut-sei=Yoden en-aut-mei=Midori kn-aut-name=余田みどり kn-aut-sei=余田 kn-aut-mei=みどり aut-affil-num=7 ORCID= en-aut-name=TanabeMasatada en-aut-sei=Tanabe en-aut-mei=Masatada kn-aut-name=田邉昌忠 kn-aut-sei=田邉 kn-aut-mei=昌忠 aut-affil-num=8 ORCID= en-aut-name=KawaseYoshiroh en-aut-sei=Kawase en-aut-mei=Yoshiroh kn-aut-name=川瀬良郎 kn-aut-sei=川瀬 kn-aut-mei=良郎 aut-affil-num=9 ORCID= en-aut-name=MizukawaKiichiroh en-aut-sei=Mizukawa en-aut-mei=Kiichiroh kn-aut-name=水川帰一郎 kn-aut-sei=水川 kn-aut-mei=帰一郎 aut-affil-num=10 ORCID= affil-num=1 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=2 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=3 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=4 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=5 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=6 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=7 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=8 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=9 en-affil= kn-affil=国立療養所高松病院放射線科 affil-num=10 en-affil= kn-affil=鳥取大学医学部放射線医学教室 en-keyword=IMP脳SPECT kn-keyword=IMP脳SPECT en-keyword=AVM kn-keyword=AVM en-keyword=脳梗塞後 luxury perfusion kn-keyword=脳梗塞後 luxury perfusion END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=11-12 article-no= start-page=1141 end-page=1148 dt-received= dt-revised= dt-accepted= dt-pub-year=1988 dt-pub=1988 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Septal lines in pulmonary alveolar microlithiasis with typical Kerley's lines kn-title=肺胞微石症にみられたKerley A, B, C線の解析 en-subtitle= kn-subtitle= en-abstract= kn-abstract=A 64-year-old woman without any respiratory symptoms was diagnosed as having pulmonary alveolar microlithiasis from the characteristic finding of her chest radiograms. Diffuse fine nodular shadows of microliths were seen throughout both lungs. Linear shadows, which were considered to be typical Kerley's lines (A, B, and C), were also noted. Conventional tomography and high resolution, thin-slice CT disclosed the anatomical structures and the distribution of interlobular septa in vivo, which were responsible for Kerley's lines. Lateral chest radiograms revealed oblique short linear shadows just behind the sternum, which were caused by interlobular septa at the mediastinal side of the upper lung. These shadows seemed to represent new septal lines. en-copyright= kn-copyright= en-aut-name=KojimaKanji en-aut-sei=Kojima en-aut-mei=Kanji kn-aut-name=児島完治 kn-aut-sei=児島 kn-aut-mei=完治 aut-affil-num=1 ORCID= en-aut-name=YodenMidori en-aut-sei=Yoden en-aut-mei=Midori kn-aut-name=余田みどり kn-aut-sei=余田 kn-aut-mei=みどり aut-affil-num=2 ORCID= en-aut-name=ToyamaYoshihiro en-aut-sei=Toyama en-aut-mei=Yoshihiro kn-aut-name=外山芳弘 kn-aut-sei=外山 kn-aut-mei=芳弘 aut-affil-num=3 ORCID= en-aut-name=KageyamaJunichi en-aut-sei=Kageyama en-aut-mei=Junichi kn-aut-name=影山淳一 kn-aut-sei=影山 kn-aut-mei=淳一 aut-affil-num=4 ORCID= en-aut-name=SakamotoKazuhiro en-aut-sei=Sakamoto en-aut-mei=Kazuhiro kn-aut-name=坂本和裕 kn-aut-sei=坂本 kn-aut-mei=和裕 aut-affil-num=5 ORCID= en-aut-name=MiyamotoTsutomu en-aut-sei=Miyamoto en-aut-mei=Tsutomu kn-aut-name=宮本勉 kn-aut-sei=宮本 kn-aut-mei=勉 aut-affil-num=6 ORCID= en-aut-name=HosokawaNobuyuki en-aut-sei=Hosokawa en-aut-mei=Nobuyuki kn-aut-name=細川敦之 kn-aut-sei=細川 kn-aut-mei=敦之 aut-affil-num=7 ORCID= en-aut-name=SeoHiroyuki en-aut-sei=Seo en-aut-mei=Hiroyuki kn-aut-name=瀬尾裕之 kn-aut-sei=瀬尾 kn-aut-mei=裕之 aut-affil-num=8 ORCID= en-aut-name=SatohKatashi en-aut-sei=Satoh en-aut-mei=Katashi kn-aut-name=佐藤功 kn-aut-sei=佐藤 kn-aut-mei=功 aut-affil-num=9 ORCID= en-aut-name=OhkawaMotoomi en-aut-sei=Ohkawa en-aut-mei=Motoomi kn-aut-name=大川元臣 kn-aut-sei=大川 kn-aut-mei=元臣 aut-affil-num=10 ORCID= en-aut-name=TamaiToyosato en-aut-sei=Tamai en-aut-mei=Toyosato kn-aut-name=玉井豊理 kn-aut-sei=玉井 kn-aut-mei=豊理 aut-affil-num=11 ORCID= en-aut-name=TanabeMasatada en-aut-sei=Tanabe en-aut-mei=Masatada kn-aut-name=田邉正忠 kn-aut-sei=田邉 kn-aut-mei=正忠 aut-affil-num=12 ORCID= affil-num=1 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=2 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=3 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=4 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=5 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=6 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=7 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=8 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=9 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=10 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=11 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=12 en-affil= kn-affil=香川医科大学放射線医学教室 en-keyword=肺胞微石症 kn-keyword=肺胞微石症 en-keyword=Kerley線 kn-keyword=Kerley線 en-keyword=小葉間隔壁 kn-keyword=小葉間隔壁 en-keyword=間質性パターン kn-keyword=間質性パターン END start-ver=1.4 cd-journal=joma no-vol=100 cd-vols= no-issue=11-12 article-no= start-page=1113 end-page=1116 dt-received= dt-revised= dt-accepted= dt-pub-year=1988 dt-pub=1988 dt-online= en-article= kn-article= en-subject= kn-subject= en-title=Factor analysis of gated pulmonary ventilation study with Kr-81m gas in normal volunteers kn-title=呼吸同調装置による(81m)Kr-ガス持続吸入シンチグラフィのfactor analysis―正常者の検討 en-subtitle= kn-subtitle= en-abstract= kn-abstract=Factor analysis of the steady state breathing cycle using Kr-81m gas wa performed in 7 normal volunteers. Two-factor analysis showed diaphragmatic and thoracic components, including the large airway space component. The contribution of the former was 19.2%±2.1% SD, and the contribution of the latter was 80.2%±2.1% SD. Three-factor analysis showed diaphragmatic (14.3% ±3.3% SD), thoracic (55.7% ±2.1% SD) and large airway space (29.5% ±12.1% SD) components. Factor analysis of dynamic structures appears to be a very useful method for the study of lung ventilation. en-copyright= kn-copyright= en-aut-name=TanabeMasatada en-aut-sei=Tanabe en-aut-mei=Masatada kn-aut-name=田邉正忠 kn-aut-sei=田邉 kn-aut-mei=正忠 aut-affil-num=1 ORCID= en-aut-name=KawaseYoshiroh en-aut-sei=Kawase en-aut-mei=Yoshiroh kn-aut-name=川瀬良郎 kn-aut-sei=川瀬 kn-aut-mei=良郎 aut-affil-num=2 ORCID= en-aut-name=SeoHiroyuki en-aut-sei=Seo en-aut-mei=Hiroyuki kn-aut-name=瀬尾裕之 kn-aut-sei=瀬尾 kn-aut-mei=裕之 aut-affil-num=3 ORCID= en-aut-name=SatohKatashi en-aut-sei=Satoh en-aut-mei=Katashi kn-aut-name=佐藤功 kn-aut-sei=佐藤 kn-aut-mei=功 aut-affil-num=4 ORCID= en-aut-name=HosokawaNobuyuki en-aut-sei=Hosokawa en-aut-mei=Nobuyuki kn-aut-name=細川敦之 kn-aut-sei=細川 kn-aut-mei=敦之 aut-affil-num=5 ORCID= en-aut-name=MiyamotoTsutomu en-aut-sei=Miyamoto en-aut-mei=Tsutomu kn-aut-name=宮本勉 kn-aut-sei=宮本 kn-aut-mei=勉 aut-affil-num=6 ORCID= en-aut-name=MatsunoShinsuke en-aut-sei=Matsuno en-aut-mei=Shinsuke kn-aut-name=松野慎介 kn-aut-sei=松野 kn-aut-mei=慎介 aut-affil-num=7 ORCID= affil-num=1 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=2 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=3 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=4 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=5 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=6 en-affil= kn-affil=香川医科大学放射線医学教室 affil-num=7 en-affil= kn-affil=香川医科大学放射線医学教室 en-keyword=(81m)Kr-ガス kn-keyword=(81m)Kr-ガス en-keyword=factor analysis kn-keyword=factor analysis en-keyword=ventilation study kn-keyword=ventilation study en-keyword=正常者 kn-keyword=正常者 END
