A 61-year-old man with obstructive jaundice caused by distal bile duct cancer recurrence was admitted to our hospital. As treatment, we performed endoscopic ultrasound-guided hepaticogastrostomy and placed a self-expanding metal stent. Computed tomography was performed immediately after the procedure to ensure proper stent placement. Although repeat imaging the next day revealed that the stent on the hepaticogastrostomy route had shortened, the stent on the gastric side maintained sufficient length. However, 11 days after the procedure, the stomach-to-liver distance had increased, and the stent on the gastric side was significantly shortened. Endoscopic imaging revealed that the stent had almost migrated, and we added a fully covered self-expanding metal stent into the previous metallic stent via the hepaticogastrostomy route. The patient was discharged 19 days after the initial procedure without complications. Computed tomography performed 40 days after the hepaticogastrostomy revealed that the initial stent had migrated into the abdominal cavity, but the second stent was in an appropriate position. In conclusion, repeated monitoring by computed tomography after hepaticogastrostomy procedure may be an effective method for preventing stent migration in high-risk cases.

Background/Aims: Metabolic dysfunction-associated steatotic liver disease (MASLD) was recently proposed as an alternative disease concept to nonalcoholic fatty liver disease (NAFLD). We aimed to investigate the prognosis of patients with biopsy-confirmed MASLD using data from a multicenter study. Methods: This was a sub-analysis of the Clinical Outcome Nonalcoholic Fatty Liver Disease (CLIONE) study that included 1,398 patients with NAFLD. Liver biopsy specimens were pathologically diagnosed and histologically scored using the NASH Clinical Research Network system, the FLIP algorithm, and the SAF score. Patients who met at least one cardiometabolic criterion were diagnosed with MASLD. Results: Approximately 99% of cases (n=1,381) were classified as MASLD. Patients with no cardiometabolic risk (n=17) had a significantly lower BMI than patients with MASLD (20.9 kg/m2 vs. 28.0 kg/m2, P<0.001), in addition to significantly lower levels of inflammation, ballooning, NAFLD activity score, and fibrosis stage based on liver histology. These 17 patients had a median follow-up of 5.9 years, equivalent to 115 person-years, with no deaths, liver-related events, cardiovascular events, or extrahepatic cancers. The results showed that the prognosis for pure MASLD was similar to that for the original CLIONE cohort, with 47 deaths and one patient who underwent orthotopic liver transplantation. The leading cause of death was extrahepatic cancer (n=10), while the leading causes of liver-related death were liver failure (n=9), hepatocellular carcinoma (n=8), and cholangiocarcinoma (n=4). Conclusions Approximately 99% of NAFLD cases were considered MASLD based on the 2023 liver disease nomenclature. The NAFLD-only group, which is not encompassed by MASLD, had a relatively mild histopathologic severity and a favorable prognosis. Consequently, the prognosis of MASLD is similar to that previously reported for NAFLD.

Background/Aims: Although endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is performed globally, the procedure remains challenging. Guidewire manipulation is the most difficult step, and there are few reports on the factors associated with unsuccessful guidewire manipulation. This study aimed to assess the significance of the puncture angle on EUS images and identify the most effective guidewire rescue method for patients with unsuccessful guidewire manipulation. Methods: We retrospectively enrolled 115 patients who underwent EUS-HGS between May 2016 and April 2022 at two centers. The puncture angle between the needle and the intrahepatic bile duct was measured through EUS movie records. Results: Guidewire manipulation was unsuccessful in 28 patients. Receiver operating characteristic (ROC) curves identified an optimal puncture angle cutoff value of 85° (cutoff value, 85°; area under the ROC curve, 0.826; sensitivity, 85.7%; specificity, 81.6%). Multivariate analysis demonstrated that a puncture angle <85° was a significant risk factor for unsuccessful guidewire manipulation (odds ratio, 19.8; 95% confidence interval, 6.42–61.5; p<0.001). Among the 28 unsuccessful cases, 24 patients (85.7%) achieved successful guidewire manipulation using various rescue methods. Conclusions The puncture angle observed on EUS is crucial for guidewire manipulation. A puncture angle of <85° was associated with unsuccessful guidewire manipulation.

In 1952, the Japanese Society for Hygiene had once passed a resolution at its 22nd symposium on population control, recommending the suppression of population growth based on the idea of cultivating a healthier population in the area of eugenics. Over half a century has now passed since this recommendation; Japan is witnessing an aging of the population (it is estimated that over 65-year-olds made up 27.7% of the population in 2017) and a decline in the birth rate (total fertility rate 1.43 births per woman in 2017) at a rate that is unparalleled in the world; Japan is faced with a "super-aging" society with low birth rate. In 2017, the Society passed a resolution to encourage all scientists to engage in academic researches to address the issue of the declining birth rate that Japan is currently facing. In this commentary, the Society hereby declares that the entire text of the 1952 proposal is revoked and the ideas relating to eugenics is rejected. Since the Society has set up a working group on the issue in 2016, there have been three symposiums, and working group committee members began publishing a series of articles in the Society's Japanese language journal. This commentary primarily provides an overview of the findings from the published articles, which will form the scientific basis for the Society's declaration. The areas we covered here included the following: (1) improving the social and work environment to balance between the personal and professional life; (2) proactive education on reproductive health; (3) children's health begins with nutritional management in women of reproductive age; (4) workplace environment and occupational health; (5) workplace measures to counter the declining birth rate; (6) research into the effect of environmental chemicals on sexual maturity, reproductive function, and the children of next generation; and (7) comprehensive research into the relationship among contemporary society, parental stress, and healthy child-rearing. Based on the seven topics, we will set out a declaration to address Japan's aging society with low birth rate.

Although there are a number of reported cases of increased cerebral blood flow during exercise, there are no reports on the relation between changes of blood flow during exercise and attentional function. The purpose of this study is to clarify the relation between changes of blood flow during exercise with AT intensity and attentional function, using near-infrared spectral analysis. The subjects were 10 healthy males. The research protocol was to conduct steady load exercise. We randomly conducted two invention trials: 1) an exercise/task trial in which a trail making test (TMT) was performed as an attentional assignment during steady load exercise, and 2) a rest/task trial in which TMT was performed during rest as a control. As a result, we observed the following: increase of oxy-Hb in the prefrontal cortex during AT exercise, the significant shortening of TMT during exercise from 69.1±10.2 seconds to63.2±7.2seconds, and, with further control, that the more oxy-Hb rises, the more TMT time is shortened. From these results, it is suggested that 10 minutes of exercise would improve attentional function, and furthermore, there is a possibility that increased cerebral blood flow may be involved with the improvement of attentional function.

The aim of the present study was to examine whether amount of oral cortisol, immunoglobulin A (IgA), chromogranin A (CgA) and inflammatory cytokines, might be affected by prolonged strenuous exercise. Ten young male volunteers either exercised on recumbent ergometer at 75 % VO₂ max for 60 min (exercise session) or sat quietly (resting session). Saliva samples were obtained at 60 min intervals during sessions for measurements of salivary stress markers (cortisol, IgA and CgA), salivary inflammatory cytokines, such as interleukin-1β (IL-1β), interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) and osmolality. Saliva flow rate was decreased and saliva osmolality was increased during the 60-min exercise. Saliva cortisol and CgA concentrations and secretion rates were increased during and after the exercise, whereas saliva IgA concentration and secretion rates were decreased after the exercise. Salivary inflammatory cytokines was increased during and after the exercise. The present findings suggested a single bout of prolonged strenuous exercise caused a transient increase in the salivary cortisol, CgA and inflammatory cytokines levels, whereas salivary IgA concentration and secretion rates were decreased after the exercise. Further studies, however, are needed to delineate whether or not salivary stress markers and inflammatory cytokines may be used as biological markers to determine the host responses to acute prolonged strenuous exercise.

The purpose of this study was to examine the effects of aquatic exercise training on the trunk muscles function and activities of daily living in abdominal obese women. Nineteen abdominal obese (abdominal circumference: 90 cm or more) and fifteen age-matched non-obese women were recruited as participants in this study. The aquatic exercise training (60 min/day, three days/week for 8 weeks) based on abdominal twists for activating the trunk muscle function. Physical parameters, biochemical characteristics, arteriosclerotic parameters and activities of daily living scores were assessed before and after the training period. In both groups showed abdominal circumference, percent of body fat, blood pressure and lower extremity muscle strength increased significantly after aquatic exercising training. In particular, endurance capacity of abdominal and back muscles increased significantly and activities of daily living scores were significantly improved in the obese group. Moreover, the improvement in the strength of lower extremities and improvement in the activities of daily living scores, such as climbing and descending stairs, in the obese group tended to be higher than non-obese women. Additionally, in abdominal obese group, the amount of the reduction of abdominal circumference was significantly associated with that of the increase in the strength of lower extremities. Taken together, these findings suggest the possibilities that the present aquatic exercise training based on trunk muscle exercise improving the function of trunk and lower extremity muscles with reduction in the abdominal obesity, contributing to improve activities of daily living in abdominal obese women.

We performed redo coronary artery bypass grafting (CABG) using lateral MIDCAB for 3 patients with severe symptomatic ischemia in the left circumflex system alone. When the descending thoracic aorta had no atherosclerotic lesions on chest CT, it was selected as the inflow of the bypass. According to the location of the target artery, we undertook sequential or T-composite off-pump bypass using the radial artery through a left lateral thoracotomy. On the other hand, when the descending aorta was diseased, the left axillary artery was chosen as the inflow of the bypass. We selected the saphenous vein as a conduit to obtain sufficient graft length. A proximal anastomosis was made through a left infraclavicular incision, and then a distal anastomosis was done through a left lateral thoracotomy without cardiopulmonary bypass. Moreover, care was taken not to kink the grafts. The postoperative course was uneventful in all patients. Lateral MIDCAB technique was useful for redo revascularization to the circumflex system. We believe that selection of bypass conduits, routes, and bypass inflow according to the individual patient is essential for the procedure.
