Changes in Personal Behaviors During and After the COVID-19 Pandemic: A Nationwide Three-Year Longitudinal Study in Japan.

Few longitudinal studies have examined the impact of the COVID-19 pandemic on personal behaviors. This study investigated changes in four social behaviors among the Japanese public during and after the COVID-19 pandemic, using four-wave longitudinal data (2020-2023) from the Japan COVID-19 and Society Internet Survey (JACSIS). In total, 8622 respondents continuously participated in the surveys.

Impact of direct mesenteric perfusion on malperfusion in acute type A aortic dissection repair.

Objectives: Mesenteric malperfusion in acute aortic dissection remains a life-threatening complication with no standardized treatment strategy. This study aimed to describe and evaluate the outcomes of our integrated approach combining exploratory laparotomy, immediate mesenteric reperfusion, and central aortic repair.

Methods: We retrospectively reviewed patients with acute aortic dissection with a preoperative diagnosis of mesenteric malperfusion who were treated between August 2011 and November 2022.

Residency Program Directors' Perspectives on Overtime Duty Hours and Professional Development Time in Japan.

Purpose: This study aimed to explore the perspectives of residency program directors in Japan regarding overtime duty hours and the balance between clinical training and self-improvement activities. This study explores the impact of work-hour regulations on resident well-being and training quality, contributing to global discourse on medical education reform.

Participants And Methods: A cross-sectional survey was distributed to 701 residency training hospitals across Japan to investigate their readiness for new duty-hour limits under the Medical Care Act, which categorizes working hours into Level A (960 hours/year), Level B (1440 hours/year), and Level C-1 (1920 hours/year).

Effect of Low-dose Administration of Carperitide for Acute Heart Failure: the LASCAR-AHF trial.

Background: The effects of low-dose carperitide on long-term clinical outcomes of patients with acute heart failure (AHF) have not yet been fully elucidated. This study aimed to evaluate the effects of low-dose intravenous carperitide on the long-term clinical outcomes of patients with AHF.

Methods: In this multicentre, open-label, randomised controlled trial, 247 patients with AHF received low-dose carperitide intravenously with standard treatment or a matching standard treatment for 72 h from November 2014 to March 2021 across nine sites in Japan.
