Psychological Effects on Healthcare Workers during the COVID-19 Outbreak: A Single-center Study at a Tertiary Hospital in Tokyo, Japan.

Objective The present study analyzed the psychological status of healthcare workers in Japan and the influencing factors during the 2019 coronavirus disease pandemic. Methods An online survey was conducted from July 22 to August 21, 2020. A total of 328 of the 1,029 medical staff members in our university hospital participated in the study.

Heterogeneity of hemodynamic parameters in untreated primary hypertension, and individualization of antihypertensive therapy based on noninvasive hemodynamic measurements.

Noninvasive measurement of hemodynamic parameter was undertaken in 240 patients with untreated primary hypertension using impedance cardiography (ICG) in outpatient clinics. High output was defined as a cardiac index (CI) >3.6 L/minute/m(2) and high resistance was defined as the total peripheral resistance index (TPRI) >2700 dyne·s·m(2)/cm(5).

Aldosterone blockade by Spironolactone improves the hypertensive vascular hypertrophy and remodeling in angiotensin II overproducing transgenic mice.

Objectives And Background: Recent evidence has revealed that aldosterone (ALDO) is produced in the vasculature, and acts directly in the cardiovascular system. This study was designed to examine the role of ALDO in the process of long-term renin-angiotensin system (RAS) induced vascular remodeling.

Material And Method: Hypertensive transgenic mice that overproduce angiotensin II (AngII), i.

Delayed enhancement on computed tomography in abdominal aortic aneurysm wall.

The purpose of this study was to evaluate delayed enhancement (DE) of the aortic wall of atherosclerotic aneurysms using computed tomography and to evaluate the relationships between DE and wall thickness of abdominal aortic aneurysm (AAA), diameter of AAA, serum levels of C-reactive protein (CRP) which indicate inflammation status, and pathological findings. Computed tomographic images of atherosclerotic AAA in 110 patients were studied between July 2001 and March 2003. Computed tomography (CT) scanning included unenhanced, enhanced early, and enhanced delayed phases.
