Effectiveness of the educational training program for Japanese chief residents: A one-year pilot study.

Background: Multi-institutional faculty development programs for chief residents were lacking in Japan. This study evaluated the effectiveness of the program for enhancing the knowledge and behaviors of chief residents at the national level.

Methods: Six participants completed self-assessment questionnaires at three points: before, immediately after, and 6 months post-program.

Short-term outcomes of robot-assisted versus conventional minimally invasive esophagectomy: A propensity score-matched study via a nationwide database.

Background: The advantages of robot-assisted minimally invasive esophagectomy (RA-MIE) over conventional minimally invasive esophagectomy (C-MIE) are unknown. This nationwide large-scale study aimed to compare surgical outcomes between RA-MIE and C-MIE using rigorous propensity score methods, including detailed covariates and relevant outcomes.

Methods: This Japanese nationwide retrospective cohort study included RA-MIE or C-MIE for esophageal malignant tumors performed between October 2018 and December 2019 and registered in the Japanese National Clinical Database.

Striosome circuitry stimulation inhibits striatal dopamine release and locomotion.

The mammalian striatum is divided into two types of anatomical structures: the island-like, mu opioid receptor (MOR)-rich striosome compartment and the surrounding matrix compartment. Both compartments have two types of spiny projection neurons (SPNs), dopamine receptor D1 (D1R)-expressing direct pathway SPNs (dSPNs) and dopamine receptor D2 (D2R)-expressing indirect pathway SPNs. These compartmentalized structures have distinct roles in the development of movement disorders, although the functional significance of the striosome compartment for motor control and dopamine regulation remains to be elucidated.

Factors associated with prefectural level physical activity in Japan: An ecological study.

Background: Physical activity inequalities are an important global concern; nonetheless, few studies have comprehensively examined the association between physical activity inequalities and related factors. We aimed to explore factors associated with regional inequalities in physical activity in Japan.

Methods: We investigated the relationship of individual, psychological/behavioral, social, and built-environmental factors with the proportion of individuals with exercise habits across Japanese prefectures.

Examining the content validity of the Comprehensive Assessment of Functioning for Mental Illness-Subjective Version (CAMI-S) with reference to the framework of the International Classification of Functioning, Disability, and Health (ICF).

Aim: To support the achievement of life goals and social participation of persons with mental illness, based on the World Health Organization's International Classification of Functioning, Disability, and Health (ICF), we generated items, identified domains, and examined the content validity of the Comprehensive Assessment of Functioning for Mental Illness-Subjective Version (CAMI-S). The purpose was to assess patients' strengths and weaknesses by incorporating the patient and public involvement perspective.

Methods: Focus group interviews on the items to be included were conducted with Group A.

The genomic basis of childhood T-lineage acute lymphoblastic leukaemia.

T-lineage acute lymphoblastic leukaemia (T-ALL) is a high-risk tumour that has eluded comprehensive genomic characterization, which is partly due to the high frequency of noncoding genomic alterations that result in oncogene deregulation. Here we report an integrated analysis of genome and transcriptome sequencing of tumour and remission samples from more than 1,300 uniformly treated children with T-ALL, coupled with epigenomic and single-cell analyses of malignant and normal T cell precursors. This approach identified 15 subtypes with distinct genomic drivers, gene expression patterns, developmental states and outcomes.

Heterogeneous Effects of Intensive Glycemic and Blood Pressure on Cardiovascular Events Among Diabetes by Living Arrangements.

Background: Although living alone versus with others is a key social element for cardiovascular prevention in diabetes, evidence is lacking about whether the benefit of intensive glycemic and blood pressure (BP) control differs by living arrangements. We thus aim to investigate heterogeneity in the joint effect of intensive glycemic and BP control on cardiovascular events by living arrangements among participants with diabetes.

Methods And Results: This study included 4731 participants with diabetes in the ACCORD-BP (Action to Control Cardiovascular Risk in Diabetes-Blood Pressure) trial.

Red blood cell distribution width is a useful biomarker to predict bleeding and thrombosis risks in patients with immune thrombocytopenic purpura.

Bleeding and thrombosis are common complications during immune thrombocytopenic purpura (ITP) treatment. There is a strong need to predict bleeding and thrombosis risks before ITP treatment to optimize therapy and appropriately manage these complications. We performed a retrospective cohort study of 120 patients with primary ITP to identify a biomarker to predict bleeding and thrombosis.

Effectiveness of psychological first aid in infectious disease pandemics: An overview of systematic reviews.

There is insufficient research on the usefulness of psychological interventions, such as psychological first aid (PFA), during outbreaks. We searched for and critically appraised systematic reviews that examined the effectiveness of PFA during infectious disease outbreaks, such as the novel coronavirus disease (COVID-19). Systematic reviews that examined the efficacy of PFA in the severe acute respiratory syndrome, Middle East respiratory syndrome coronavirus, Ebola virus disease, and COVID-19 outbreaks were searched through PubMed on February 19, 2021.

Impact of thoracic shape on the surgical outcomes of laparoscopic-assisted living donor hepatectomy.

Background: Although laparoscopic-assisted donor hepatectomy (LADH) has become the definitive procedure for harvesting living donor livers, its surgical outcomes in association with donor body shape have not been elucidated.

Methods: The impact of donor factors, including thoracic shape, on LADH outcomes was retrospectively investigated. Thoracic anthropometric data were examined in all LADHs with a left/right graft between 2013 and 2022.

Association between eGFR and neurological outcomes among patients with out-of-hospital cardiac arrest: A nationwide prospective study in Japan.

Aim: We aimed to investigate the association between estimated glomerular filtration rate and prognosis in out-of-hospital cardiac arrest patients and explore the heterogeneity of the association.

Methods: Patients experiencing out-of-hospital cardiac arrest due to medical causes and registered in the JAAM-OHCA Registry between June 2014 and December 2019 were stratified into shockable rhythm, pulseless electrical activity, and asystole groups according to the cardiac rhythm at the scene. The primary outcome was a 1-month favorable neurological status.

Recurrence of solitary plasmacytoma in the liver 10 years after the onset of multiple bone lesions.

A 79-year-old man presented with a history of solitary plasmacytoma in the bone 10 years ago. Chemoradiotherapy was effective, and remission was maintained with intermittent treatment at relapse of the bone lesions. One year after the last treatment, a follow-up computed tomography (CT) scan revealed multiple liver masses, and a liver biopsy revealed plasmacytoma.

Identification of patients at high risk for recurrence in carcinoma of the ampulla of Vater: Analysis in 460 patients.

Aim: Carcinoma of the ampulla of Vater (CAV) shows a favorable prognosis compared to that with the other periampullary tumors, while some cases have a poor prognosis. The aims of the present study are to clarify the clinicopathological factors associated with poor recurrence-free survival (RFS) in patients with CAV after curative resection and to validate the usefulness of adjuvant chemotherapy (AC).

Patients: The study design is a multicenter retrospective cohort study.
