| 抄録 | Although partial nephrectomy (PN) is preferred over radical nephrectomy (RN) for preserving renal function in patients with cT1 renal cancer, its impact on cardiovascular events (CVe) remains controversial. This study aimed to compare PN and RN in regard to the occurrence of CVe, including cerebrovascular events and exacerbation of hypertension (HT). We retrospectively analyzed 418 consecutive patients who underwent PN or RN for cT1 renal cancer. Propensity score-matching analysis was used to adjust for imbalances between patients who underwent PN and RN, leaving 102 patients in each group. The 5-year probability of cumulative CVe incidence was 6% in the PN group and 12% in the RN group (p=0.03), with a median follow-up of 73.5 months. The statistical significance was retained after propensity score matching for patients without preoperative proteinuria (p=0.03). For all CVe including cerebrovascular events and exacerbation of HT analyzed, PN provided a lower probability of occurrence than RN in patients with small renal cancers. |

| 抄録 | Nesidioblastosis, also known as persistent hyperinsulinemic hypoglycemia, is usually observed in children and infants, although more recently adult-onset nesidioblastosis has also been described. We present a case of nesidioblastosis in a 78-year-old man that was detected by 111In-pentetreotide single photon emission computed tomography (SPECT/CT). The patient was transferred to our hospital’s emergency department in a hypoglycemic coma. Dynamic enhanced CT could detect no lesion in the pancreas, but an 111In-pentetreotide SPECT/CT scan performed after a similar episode four weeks later showed increased focal uptake at the head of the pancreas. The results of a selective arterial calcium injection test were negative. After careful consideration and discussion among colleagues, surgical intervention was selected, and a pancreaticoduodenectomy was performed. On histology, there were elevated numbers of Langerhans islets in the pancreatic head, and the islets themselves appeared enlarged. Hypertrophic β-cells comprised the majority, but α-cells, δ-cells and pancreatic polypeptide were also detected in the islets. Based on the histopathological results and repeated hyperinsulinemic hypoglycemic crises, the patient was finally diagnosed with adult-onset nesidioblastosis. He had no hypoglycemic symptoms during outpatient follow-up examination. Since 111In-pentetreotide SPECT/CT may be able to detect nesidioblastosis, clinicians should consider this relatively new-modality examination when encountering such cases. |

| 抄録 | We investigated patients with migraine or migraine variants who exhibited focal cerebral hypoperfusion on arterial spin-labeled (ASL) magnetic resonance (MR) imaging along with neurological symptoms. Fourteen patients with migraine demonstrated focal cerebral hypoperfusion. Three other patients did not have a history of recurrent headaches but exhibited comparable cerebral hypoperfusion to migraine patients on ASL-MRI in addition to neurological symptoms. Patients with migraine may present with neurological symptoms associated with cortical spreading depression during, after, or even without a headache phase. Additionally, the isolated neurological symptoms may be caused by a pathophysiology identical to that of migraine but without presenting with recurrent headaches. |

| 抄録 | Radon is a known risk factor for lung cancer; however, it can be used beneficially, such as in radon therapy. We have previously reported the enhancement of antioxidant effects associated with trace amounts of oxidative stress as one of the positive biological effects of radon inhalation. However, the biological effects of radon inhalation are incompletely understood, and more detailed and comprehensive studies are required. Although several studies have used proteomics to investigate the effects of radon inhalation on body proteins, none has focused on brain proteins. In this study, we evaluated the expression status of proteins in murine brains using proteomic and multivariate analyses to identify those whose expressions changed following two days of radon inhalation at a concentration of 1,500 Bq/m3. We found associations of radon inhalation with the expressions of seven proteins related to neurotransmission and heat shock. These proteins may be proposed as biomarkers indicative of radon inhalation. Although further studies are required to obtain the detailed biological significance of these protein alterations, this study contributes to the elucidation of the biological effects of radon inhalation as a low-dose radiation. |

| 抄録 | It has not been clear how recipient age affects the incidence of serious complications after pediatric living donor liver transplantation (LDLT). We investigated the records of 42 pediatric patients receiving LDLT, dividing our sample into two groups: the infant group (aged < 1 year) and the non-infant group (aged ≥ 1 year and ≤15 years). The primary outcome was postoperative complications assessed using the Clavien-Dindo classification. Multivariate analysis using the Cox regression model was applied to adjust for confounding factors in assessing the incidence of Clavien-Dindo grade ≥ III (C-D ≥ III) complications. The incidence of C-D ≥ III complications was higher in the non-infant group (46.2%) than in the infant group (12.5%) (odds ratio 6.00, 95% confidence interval [CI] 1.13-31.88, p=0.03). In multivariate analysis using the Cox regression model, the Graft-to-Recipient Weight Ratio (GRWR) was independently associated with the incidence of C-D ≥ III complications (hazard ratio [HR] 0.62, 95%CI 0.40-0.95, p=0.03), but being an infant was not (HR 0.84, 95%CI 0.35-1.98, p=0.68). In conclusion, the incidence of C-D ≥ III complications was higher in the non-infant group than in the infant group, but this was largely a function of GRWR: multivariate analysis revealed that GRWR was independently associated with complications. |

| 抄録 | During the coronavirus pandemic, face-to-face simulation education became impossible. Therefore, we aimed to develop remote-access simulation education with a sense of realism through Information and Communication Technology (ICT) using a perinatal whole-body management and delivery simulator. In September 2021, we administered a multi-center simultaneous remote simulation based on our developed model. Ten universities in the Chugoku–Shikoku region were connected via a web-conferencing system to a live broadcast of a virtual vaginal birth in which a fictional hospitalized pregnant woman experienced accelerated labor and gave birth through vacuum delivery for fetal distress. A Video on Demand (VOD) was made beforehand using a new simulator that allowed for a visual understanding of the process of the inter-vaginal examination. We provided a participatory program that enhanced the sense of realism by combining VOD and real-time lectures on each scenario, with two-way communication between participants and trainee doctors using a chat function. Most participants answered “satisfied” or “very satisfied” with the content, level of difficulty, and level of understanding. From November 2021, we have used the videos of all processes in face-to-face classes. Our construction of a high-flexibility education system using remote simulation in the field of obstetrics and gynecology, especially in the vaginal delivery module, is unique, creative, and sustainable. |

| 抄録 | The Briganti nomogram (cut-off value 5%) is commonly used to determine the indications for pelvic lymph node dissection (PLND) in patients with prostate cancer. We retrospectively analyzed the potential oncological benefit of PLND based on the 5% cut-off value on the Briganti nomogram. We obtained the data from the Medical Investigation Cancer Network (MICAN) Study, which included 3,463 patients who underwent a radical prostatectomy (RP) at nine institutions in Japan between 2010 and 2020. We included patients with Briganti scores ≥ 5% and a follow-up period ≥6 months and excluded patients categorized in the very high-risk group (based on NCCN categories); a final total of the cases of 1,068 patients were analyzed. The biochemical recurrence (BCR)-free survival was significantly worse in the patients who underwent PLND compared to those who did not (p=0.019). A multivariate analysis showed that high prostate-specific antigen (PSA) levels (p<0.001) and an advanced T-stage (p=0.018) were significant prognostic factors for BCR, whereas PLND had no effect on BCR (p=0.059). Thus, PLND in patients with prostate cancer whose Briganti score was 5% did not provide any oncological benefit. Further research is necessary to determine the indication criteria for conducting PLND. |

| 抄録 | We report a case of a large vestibular schwannoma in an 80-year-old female patient that shrank after palliative Gamma Knife radiosurgery (GKS). Neurological symptoms included hearing deterioration and facial palsy. The tumor volume was 21.9 mL. Craniotomy was considered high-risk, and conventional GKS was risky, owing to the risk of transient enlargement. Therefore, GKS was performed on only a portion of the tumor. The marginal dose (12 Gy) volume was 3.8 mL (17.4%). The tumor began to shrink after transient enlargement. Sixty months later, the tumor volume was only 3.1 mL, and the patient was able to maintain independent activities of daily living without salvage treatment. |

| 抄録 | In the clinical course of malignant melanoma, which can metastasize to multiple organs, gallbladder metastases are rarely detected. A 69-year-old man who underwent resection of a primary malignant melanoma was subsequently treated with nivolumab for lung metastases and achieved complete response. Seven years after surgery, multiple nodules were found in the gallbladder, and he underwent laparoscopic cholecystectomy. The postoperative diagnosis was metastases of malignant melanoma. He has been recurrence-free 8 months after surgery. If radical resection is possible, such surgery should be performed for gallbladder metastases found in patients with other controlled lesions of malignant melanoma. |

| 抄録 | A 24-year-old Japanese female with anorexia nervosa presented to our hospital for bilateral pneumothorax, and 12-Fr thoracostomy catheters were inserted into the bilateral pleural cavities. On hospital day 9, a thoracoscopic bullectomy was performed. However, air leakage relapsed on both sides on postoperative day 1. The air leakage on the right side was particularly persistent, and we switched the drainage to a Heimlich valve. Both lungs expanded gradually and the chest tube was removed on postoperative day 19. Passive pleural drainage might be an option for prolonged air leakage after a bullectomy in patients with anorexia nervosa. |

| 抄録 | We investigated how humidified high-flow nasal cannula oxygen therapy (HFNC) with a pulmonary infection control (PIC) window as a ventilation switching indication in combination with atomizing inhalation of terbutaline affects the lung function of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). We examined 140 hospitalized AECOPD patients randomized to control and observation groups. Conventional supportive therapy and invasive mechanical ventilation with tracheal intubation were conducted in both groups, with a PIC window as the indication for ventilation switching. Noninvasive positive pressure ventilation (NIPPV) plus atomizing inhalation of terbutaline was used in the control group. In the observation group, HFNC combined with atomizing inhalation of terbutaline was used. Compared to the control group, after 48-hr treatment and treatment completion, the observation group had significantly increased levels of lung function indicators (maximal voluntary ventilation [MVV] plus forced vital capacity [FVC], p<0.05) and oxygen metabolism indicators (arterial oxygen partial pressure [PaO2], arterial oxygen content [CaO2], and oxygenation index, p<0.05). The comparison of the groups revealed that the levels of airway remodeling indicators (matrix metalloproteinase-2 [MMP-2], tissue inhibitor of metalloproteinase 2 [TIMP-2] plus MMP-9) and inflammatory indicators (interferon gamma [IFN-γ] together with interleukin-17 [IL-17], IL-10 and IL-4) were significantly lower after 48 h of treatment as well as after treatment completion (both p<0.05). These results demonstrate that HFNC with a PIC window as the indication for ventilation switching combined with atomizing inhalation of terbutaline can relieve the disorder of oxygen metabolism and correct airway hyper-reactivity. |

| 抄録 | 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. |

| 抄録 | Fracture liaison services (FLS) have been introduced in Japan and several other countries to reduce medical complications and secondary fractures. We aimed to evaluate the effects of the implementation of an FLS approach on patient outcomes during hospitalization at our hospital and over a 2-year follow-up post-injury. This retrospective cohort study included patients ≥ 60 years admitted to our hospital for hip fragility fractures between October 1, 2016, and July 31, 2020. Patient groups were defined as those treated before (control group, n=238) and after (FLS group, n=196) establishment of the FLS protocol at our institution. The two groups were compared in terms of time to surgery, length of hospital stay, and the incidence of complications after admission, including secondary hip fracture and mortality rates. The follow-up period was 24 months. FLS focuses on early surgery within 48 h of injury and assessing osteoporosis treatment before injury to guide post-discharge anti-osteoporosis medication. FLS reduced the length of hospital stay (p<0.001) and the prevalence of complications after admission (p<0.001), particularly cardiovascular disease, and it increased adherence to anti-osteoporosis medication. These FLS effects resulted in lower secondary hip fracture and mortality rates at 12 and 24 months post-injury. FLS for fragility hip fractures can improve patient outcomes during hospitalization and over a 2-year follow-up period. |

| 抄録 | We propose a sitting position that achieves both high image quality and a reduced radiation dose in elbow joint imaging by area detector computed tomography (ADCT), and we compared it with the ‘superman’ and supine positions. The volumetric CT dose index (CTDIvol) for the sitting, superman, and supine positions were 2.7, 8.0, and 20.0 mGy and the dose length products (DLPs) were 43.4, 204.7, and 584.8 mGy • cm, respectively. In the task-based transfer function (TTF), the highest value was obtained for the sitting position in both bone and soft tissue images. The noise power spectrum (NPS) of bone images showed that the superman position had the lowest value up to approx. 1.1 cycles/mm or lower, whereas the sitting position had the lowest value when the NPS was greater than approx. 1.1 cycles/mm. The overall image quality in an observer study resulted in the following median Likert scores for Readers 1 and 2: 5.0 and 5.0 for the sitting position, 4.0 and 3.5 for the superman position, and 4.0 and 2.0 for the supine position. These results indicate that our proposed sitting position with ADCT of the elbow joint can provide superior image quality and allow lower radiation doses compared to the superman and supine positions. |

| 抄録 | Soft-tissue sarcoma (STS) is a heterogeneous group of rare tumors originating predominantly from the embryonic mesoderm. Despite the development of combined modalities including radiotherapy, STSs are often refractory to antitumor modalities, and novel strategies that improve the prognosis of STS patients are needed. We previously demonstrated the therapeutic potential of two telomerase-specific replication-competent oncolytic adenoviruses, OBP-301 and tumor suppressor p53-armed OBP-702, in human STS cells. Here, we demonstrate in vitro and in vivo antitumor effects of OBP-702 in combination with ionizing radiation against human STS cells (HT1080, NMS-2, SYO-1). OBP-702 synergistically promoted the antitumor effect of ionizing radiation in the STS cells by suppressing the expression of B-cell lymphoma-X large (BCL-xL) and enhancing ionizing radiation-induced apoptosis. The in vivo experiments demonstrated that this combination therapy significantly suppressed STS tumors’ growth. Our results suggest that OBP-702 is a promising antitumor reagent for promoting the radiosensitivity of STS tumors. |

| 抄録 | Chronic graft-versus-host disease (GVHD) is a major cause of late death and morbidity following allogeneic hematopoietic cell transplantation (HCT), but its pathogenesis remains unclear. Recently, haplo-identical HCT with post-transplant cyclophosphamide (Haplo-HCT with PTCY) was found to achieve a low incidence rate of acute GVHD and chronic GVHD. However, while the pathogenesis of acute GVHD following Haplo-HCT with PTCY has been well investigated, that of chronic GVHD remains to be elucidated, especially in HLA-matched HCT with PTCY. Based on its safety profile, PTCY is currently applied for the human leucocyte antigen (HLA)-matched HCT setting. Here, we investigated the mechanisms of chronic GVHD following HLA-matched HCT with PTCY using a well-defined mouse chronic GVHD model. PTCY attenuated clinical and pathological chronic GVHD by suppressing effector T-cells and preserving regulatory T-cells compared with a control group. Additionally, we demonstrated that cyclosporine A (CsA) did not show any additional positive effects on attenuation of GVHD in PTCY-treated recipients. These results suggest that monotherapy with PTCY without CsA could be a promising strategy for the prevention of chronic GVHD following HLA-matched HCT. |

| 抄録 | 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. |

| 抄録 | Vertical transmission of hepatitis B virus (HBV), especially in Asia, is a key target in the global elimination of HBV. This study assessed the effects of tenofovir disoproxil fumarate (TDF) in pregnant women for mother-to-infant transmission of HBV. A total of 122 pregnant women at our hospital met the inclusion criteria for high HBV DNA viral loads. They were randomly divided into TDF-treatment (n=70) and placebo (n=52) groups. Maternal liver function and serum HBV DNA load were tested before and after treatment. Clinical and laboratory data of infants were assayed at delivery and 7-months post-partum visit and compared between the two groups. There was no difference in clinical characteristics of participants between the two groups. There were no significant differences in liver function markers, including alanine aminotransferase, total bilirubin, blood creatinine, and blood urea nitrogen levels before and after TDF treatment. The serum HBV DNA viral load of the TDF-treated group became significantly lower than those of the control group and their own pre-medication levels. Infants showed no significant difference in body growth, including weight, height, head size, and five-min Apgar score. At 7 months after birth, 94.29% of infants in the TDF group and 86.54% of control-group infants had protective HBsAb levels ≥ 10 mIU/ml (p>0.05). The HBV infection rate of infants in the TDF-treated group was lower than that in the non-treated group. In high-HBV-DNA-load pregnant women, TDF administered from 28 weeks gestational age to delivery was associated with a lower risk of mother-to-infant transmission of HBV. |

| 抄録 | 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. |
