Disparities in co-payments for influenza vaccine among the elderly, during the COVID-19 pandemic in Japan.

Introduction: Seasonal influenza vaccination for the elderly is highly recommended during the COVID-19 pandemic. In Japan, the amount of subsidy for influenza differs among municipalities. Thus, we investigated the amount of and variation in subsidy for influenza vaccination for the elderly in 2020.

Yokukansankachimpihange Is Useful to Treat Behavioral/Psychological Symptoms of Dementia.

Yokukansankachimpihange is a Japanese herbal medicine reported to benefit anxiety and sleep disorders, and it has recently been introduced to treat behavioral and psychological symptoms of dementia. There are no multicenter studies of its effectiveness regarding dementia in Japan, and this study's main objective was to clarify the effects of Yokukansankachimpihange on behavioral and psychological symptoms of dementia in a sample of patients from multiple healthcare centers. Nine facilities affiliated with Osaka Association of Psychiatric Clinics participated in November 2013 through April 2015 and provided 32 Alzheimer's disease patients to whom Yokukansankachimpihange was orally administered for 8 weeks.

Decreased plasma brain-derived neurotrophic factor and vascular endothelial growth factor concentrations during military training.

Decreased concentrations of plasma brain-derived neurotrophic factor (BDNF) and serum BDNF have been proposed to be a state marker of depression and a biological indicator of loaded psychosocial stress. Stress evaluations of participants in military mission are critically important and appropriate objective biological parameters that evaluate stress are needed. In military circumstances, there are several problems to adopt plasma BDNF concentration as a stress biomarker.

Bacteriological evaluation of the cardiac surgery environment accompanying hospital relocation.

Purpose: Airborne bacteria in the environment are thought to be a cause of postoperative infection. With the relocation of our hospital, the operating room we had used for 35 years was replaced, changing the surgical environment for cardiac operation completely. We conducted this study to evaluate the bacteriological change in the surgical environment between the new and old operating rooms.

Right ventricular end-diastolic volume monitoring after cardiac surgery.

Introduction: In the postoperative management of cardiac surgery patients, pulmonary capillary wedge pressure (PCWP) and central venous pressure (CVP) are the most commonly used parameters of preload. However, these pressure parameters are easily affected by ventricular compliance, positive end-expiratory pressure and other factors. The aim of this study was to evaluate whether right ventricular end-diastolic volume index (RVEDVI) reflects cardiac output or ventricular preload in patients after cardiac surgery during postoperative management.

A discrepancy between Tc-99m HMPAO SPECT and Tc-99m ECD SPECT in Creutzfeldt-Jacob disease.

We observed a discrepancy between the perfusion patterns seen in single photon emission computed tomography (SPECT) images obtained using technetium-99m hexamethyl propylene amine oxime (HMPAO) and SPECT images obtained using technetium-99m ethyl cysteinate dimer (ECD) in an 84-year-old man with Creutzfeldt-Jacob disease (CJD). HMPAO-SPECT demonstrated a reduction in perfusion in the parieto-temporal regions, especially the left temporal area. However, ECD-SPECT revealed a significant reduction in the bifrontal regions.

Sequential bypass using the right gastroepiploic artery for coronary artery bypass grafting.

Objective: Since 1989, we have applied the right gastroepiploic artery (RGEA) as a third arterial conduit for coronary artery bypass grafting (CABG) and started to use sequential RGEA in 1992. We evaluated the feasibility and efficacy of sequential RGEA grafting in CABG.

Methods: From December 1990 to January 2000, 46 patients underwent CABG with sequential RGEA.
