The Current Status of Suicide and Medical Care System in Japan: An Analysis of 81,407 Patients Using the Diagnosis Procedure Combination Database.
Japan has a high suicide mortality rate compared to other developed countries. To reduce suicide mortality in Japan, it is important to systematically analyze factors related to death of patients with suicide attempt. This study aimed to analyze the characteristics of patients with suicide attempt, and the factors related to their death using the Diagnosis Procedure Combination (DPC) data- a nationally representative inpatient database. ⋯ Patients without a psychiatric diagnosis were more likely to choose means such as hanging (14.1%) than those with a psychiatric disorder. The weekend cases had a higher OR of death than weekday (Wednesday as reference) cases (Friday 1.14, p = 0.011; Saturday 1.60, p < 0.001; Sunday 1.67, p < 0.001). Based on these findings, we suggest that improving the availability and quality of psychiatric care in acute care hospitals and primary care settings, as well as enhancing the emergency department system on weekends, could help reduce the mortality of suicide attempts.

The Attributes of Physicians Assigned to Rural Clinics Designated for Areas without Physicians in Japan.
In Japan, there are rural clinics designated for areas without physicians to ensure the availability of medical care for rural area residents. The purpose of this study was to clarify the attributes of physicians working in the rural clinics. Using the 2018 Ministry of Health, Labour and Welfare data in Japan, we compared the attributes and board certifications of physicians in rural clinics with those of physicians in other clinics. ⋯ The proportion of board-certified surgery physicians within the internal medicine field in rural clinics was significantly higher than in other clinics (5%). In rural clinics, the age distribution of physicians was different from that in other clinics, and many of the physicians worked in the internal medicine field, but some of them seemed to have a mismatch between their board-certifications and their fields of practice. Further studies are necessary to clarify what the mismatches mean in rural practice.

Review Case ReportsSmall Intestinal Adenocarcinoma Arising at the Anastomotic Site after Kasai Operation for Biliary Atresia: A Case Report and Literature Review.
Biliary atresia is an obliterative cholangiopathy of unknown etiology. Hepatic portoenterostomy, in which obliterated extrahepatic bile ducts are resected and bile flow is restored, known as Kasai operation, is performed within 3 months after birth. While this operation enhances long-term survival of patients, the occurrence of primary malignant hepatic tumors has been increasing. ⋯ The patient had not experienced recurrence at 10 months after the operation. This is the first report of small intestinal adenocarcinoma arising at the anastomotic site after Kasai operation for biliary atresia. Special care should be taken for the patients after Kasai operation with acute progressive jaundice and liver dysfunction because there is a possibility of malignancy in their native liver.

Liposomal Silybin Improves Glucose and Lipid Metabolisms in Type 2 Diabetes Mellitus Complicated with Non-Alcoholic Fatty Liver Disease via AMPK/TGF-β1/Smad Signaling.
Improving hepatic glucose and lipid metabolisms is an important strategy to treat type 2 diabetes mellitus complicated with non-alcoholic fatty liver disease (T2DM-NAFLD). Silybin (SLB) has the potential hepatoprotection, while its oral bioavailability is poor. This study aims to investigate the functional role and mechanism of liposomal SLB in modulating glucose/lipid metabolism in T2DM-NAFLD. ⋯ Besides, liposomal SLB elevated AMPK phosphorylation, and decreased collagen I/III, α-smooth muscle actin (α-SMA), transforming growth factor-β1 (TGF-β1) and the phosphorylation of Smad2/3. In hepatocyte model, compound C partially reversed the effects of liposomal SLB on cell viability, glycolipid metabolism and AMPK/TGF-β1/Smad pathway activation. Liposomal SLB ameliorates hepatic glucose and lipid metabolisms in T2DM-NAFLD via activating AMPK/TGF-β1/Smad pathway, providing an efficient strategy for treating T2DM-NAFLD.
