Abstract	Background: The development of fenestrated endograft, Najuta endograft Kawasumi Laboratories, Inc, Tokyo, Japan) in thoracic endovascular aortic repair (TEVAR) has enabled the treatment of aortic arch aneurysms approaching zone 0 without the need of supra-aortic vessel branch reconstruction. However, the indications of Najuta remain controversial due to complications such as endograft collapse, which is rare and lethal. Case presentation: We here report a 75-year-old male patient with arch saccular aneurysm. Because of his liver cirrhosis, 2 debranching TEVAR has chosen as a treatment using Najuta. After extrathoracic bypass was performed, a CTAG stent graft was implanted distal to the LSCA in order to deliver Najuta stent graft steadily. Najuta stent graft was successfully positioned in zone 0. However, he was suffered from stent-graft collapse. After additional TEVAR to salvage stent-graft collapse to zone 0, he complicated type A dissection, which was treated by ascending aorta replacement. After salvage operation complicated multiorgan failure and he died.

Abstract	This study aimed to evaluate the clinical usefulness of zero-echo time(ZTE)-based magnetic resonance imaging(MRI)in planning an optimal surgical approach and applying ZTE for anatomical guidance during transcranial surgery. P atients who underwent transcranial surgery and carotid endarterectomy and for whom ZTE-based MRI and magnetic resonance angiography(MRA)data were obtained, were analyzed by creating ZTE/MRA fusion images and 3D-ZTE-based MRI models. We examined whether these images and models could be substituted for computed tomography imaging during neurosurgical procedures. Furthermore, the clinical usability of the 3D-ZTE-based MRI model was evaluated by comparing it with actual surgical views. ZTE/MRA fusion images and 3D-ZTE-based MRI models clearly illustrated the cranial and intracranial morphology without radiation exposure or the use of an iodinated contrast medium. The models allowed the determination of the optimum surgical approach for cerebral aneurysms, brain tumors near the brain surface, and cervical internal carotid artery stenosis by visualizing the relationship between the lesions and adjacent bone structures. However, ZTE-based MRI did not provide useful information for surgery for skull base lesions, such as vestibular schwannoma, because bone structures of the skull base often include air components, which cause signal disturbances in MRI. ZTE sequences on MRI allowed distinct visualization of not only the bone but also the vital structures around the lesion. This technology is minimally invasive and useful for preoperative planning and guidance of the optimum approach during surgery in a subset of neurosurgical diseases.

Abstract	Background: The clinical implications of acute phase thrombosis after surgical left atrial appendage (LAA) closure remain unclear. This study sought to determine the frequency, prognosis, and factors involved in thrombogenesis after surgical LAA occlusion. Methods: In this study, data from patients who underwent 2 types of standalone surgical LAA closure (either resection or clipping) between July 2014 and March 2020 at a single center were analyzed. Results: A total of 239 consecutive patients with atrial fibrillation underwent minimally invasive standalone surgical LAA occlusion (184 resection cases and 55 clipping cases). On postoperative day 2, electrocardiogram synchronized contrast-enhanced computed tomography (CT) was performed in 223 cases (93.3%), and echocardiography follow-up was performed in 16 cases when CT was contraindicated. Acute postoperative thrombus on the closed stump was detected in 35 cases (14.7%), of which 29 cases (15.8%) belonged to the resection group and 6 cases (10.9%) belonged to the clipping group. No significant difference was detected between the groups, and no significant predictors of acute-phase thrombosis were found. Thromboembolism occurred in 4 patients before postoperative imaging follow-up, and there was no evidence of thrombi in these patients on postoperative day 2 CT. Three months after the first CT, thrombi were no longer detected in 34 of 35 patients (97.1%). Conclusions: Thrombosis can occur after surgical LAA occlusion. Although the clinical significance is yet unclear, it may be reasonable to continue anticoagulation therapy until a lack of thrombosis is confirmed, unless there are contraindications.

Abstract	Soccer players with chronic ankle instability (CAI) may stabilize their supporting leg by the proximal joint to compensate for the ankle instability during kicking motion. This study aimed to investigate the characteristics of leg and joint stiffness of the supporting leg during side-foot kicking in soccer players with CAI. Twenty-four male collegiate-level soccer players with and without CAI participated in this study. The kinematic and kinetic data were obtained using a three-dimensional motion analysis system. Leg stiffness and joint (hip, knee, and ankle) stiffness in the sagittal and frontal planes were calculated and analyzed. The results clarified that soccer players with CAI (0.106 ± 0.053 Nm/°) had greater knee stiffness in knee adduction during the kicking cycle compared to those without CAI (0.066 ± 0.030 Nm/°;

Abstract	Objectives: : To provide targeted interventions for the prevention of first ankle sprains, this study determined the prevalence of ankle sprains in female adolescent soccer players and analyzed the correlation between the age at the first occurrence of ankle sprain and the age at menarche. Methods: : The study included 131 female participants from three club teams. The mean age was 13.37 ± 0.96 years. A survey was conducted using a questionnaire that requested information regarding the age at which the first ankle sprain occurred, age at menarche, status of ankle problems, extent to which the ankle joint problem affected playing ability, use of medical facilities or other healthcare facilities for the first or recurrent ankle sprains, and methods used to care for their ankle. Results: Ankle sprains most commonly occurred for the first time at 12 years, followed by the ages of 13, 10, and 11 years. About 25% of participants experienced their first ankle sprain at the age of menarche, 20% at 1 year after menarche, and 16% a year before menarche. The incidence of the first ankle sprain was high in the second and fifth years after starting to play soccer. Medical treatment was rarely received for the second or subsequent injury, although 36% had some sequelae. Conclusions: Adolescent female soccer players were not injured early in their soccer careers. Most players experienced their first ankle sprain at the age of 12 years, which was at or close to the age of menarche.

Abstract	Primary production is divided into new or regenerated production based on nitrate or ammonium. New production leads to a net increase in the phytoplankton abundance. Here, we investigated seasonal variations in phytoplankton uptake rates of NO₃ and NH₄ to estimate the contribution of new production (f-ratio) in the coastal region of Hokkaido, Okhotsk Sea, during ice-free period. High f-ratios (> 0.7) were observed during the spring bloom period (April and May). Relatively high contributions of over 0.4, which have not been previously reported in oligotrophic regions, were frequently observed in the summer and autumn (June to October), despite oligotrophic conditions. In winter (November and December), contributions were below 0.4, despite the relatively high nitrate concentrations. Contributions of new production to that of primary were high during the spring bloom period, summer, and autumn, while being low in the winter. Despite being a relatively eutrophic season, the low contribution in the winter is important because of a significant increase of phytoplankton in the spring bloom and its increase consumption by associated organisms. This seasonal cycle of new production likely plays an important role in the high productivity of fisheries in the study area.

Abstract	We analyzed the effect of Na-glucose cotransporter 2 inhibitors (SGLT2-I) in diabetic patients visiting our hospital. The study included 236 patients treated with SGLT2-I alone or with codiabetic drugs for at least two years. We analyzed overtime changes in glycosylated hemoglobin A1c (HbA1c) in the patients by repeated analyses of variance (ANOVA) and evaluated the therapeutic effect. HbA1c levels decreased significantly in the first six months after treatment. Afterward, they leveled off and increased slightly over the next two years. Six months after treatment, the mean (SD) of HbA1c was 8.19 (1.46) %; the mean difference dropped by 0.91%, and HbA1c in mild DM2 did not drop by below 8.0%. Overall, there was only a slight improvement. We performed multivariate logistic regression analysis using a model with or without improvement as the objective variable and several explanatory variables. Na and Hct were significant factors. They increased considerably over six months and then leveled off. eGFR significantly reduced in the hyperfiltration group six months after treatment. The annual decline rate in eGFR was also faster, even in the nonhyperfiltration group than in the healthy subjects, which may be a characteristic of renal clearance in SGLT2-I treatment. In conclusion, SGLT2-I is an excellent antidiabetic, nephroprotective agent to eliminate hyperfiltration, but unfortunately, SGLT2-I alone does not have enough power to reduce blood glucose levels. SGLT2-I, with insulin or insulin secretagogues, enhances insulin resistance, induces hyperinsulinemia, and exacerbates type 2 DM. In contrast, SGLT2-I, with noninsulin antidiabetic agents and a low-carbohydrate diet, may bring better results.

Abstract	Oral anticoagulants for atrial fibrillation are the standard approach to prevent stroke in patients with atrial fibrillation. However, oral anticoagulant therapy carries the risk of cerebral infarction recurrence, not to mention hemorrhagic complications, even under appropriate drug therapy. Surgical treatments targeting the left atrial appendage include left atrial appendage closure( LAAO) and left atrial appendage resection (LAAR). Our hospital uses AtriClip (approved and available in Japan since 2018) as a device for LAAO, and we investigated the early and long-term results of LAAO using AtriClip in our hospital. As a result, stable early to long-term results were expected for left atrial appendage closure using AtriClip device, suggesting that it may be an option that can be considered as a method for preventing stroke in patients with atrial fibrillation. But further investigation is required in the future.

Abstract	We describe a new kudoid species, Kudoa tanakai n. sp., in the scalpel sawfish, Prionurus scalprum (Actinopterygii: Acanthuriformes: Acanthuridae), from the natural water around western Japan. The plasmodia were filamentous, localized in pseudocysts in the myofibers of the trunk muscles. The occurrence of plasmodia in the trunk muscle showed no site preference. Its myxospores were spheroid, measuring 6.6-7.6 (7.0) µm by 5.8-6.9 (6.3) µm in apical view (width) and 5.7-6.6 (6.2) in length (n = 30), with four shell valves and a corresponding number of spheroid polar capsules. Shell valves lacked apical protrusions, but scanning electron microscopy revealed that one of the four shell valves had two semi-lunar flaps at its apical terminus. Nucleotide sequencing of the small and large subunit ribosomal RNA genes of the present isolate showed phylogenetic affinities to kudoid species characterized by spheroid myxospores, such as K. musculoliquefaciens, K. hemiscylli, and K. carcharhini, but was molecularly and morphometrically distinct from these and other kudoid species. For direct comparison, Kudoa hemiscylli was collected from the Pacific spadenose shark, Scoliodon macrorhynchos (Elasmobranchii: Carcharhiniformes: Carcharhinidae), in the South China Sea off Guangdong Province, China, and the myxospore surface of the species was observed using scanning electron microscopy. Our study describes the new host and distribution record of this kudoid species originally described from a variety of elasmobranchs in the Australian Coral Sea.
