Effectiveness of SARS-CoV-2 vaccines on hemodialysis patients in Japan: A nationwide cohort study.

Introduction: This study compared the outcomes of dialysis patients who received SARS-CoV-2 vaccine with those who did not use data from the Japanese COVID-19 registry.

Methods: A total of 1260 dialysis patients with confirmed positive SARS-CoV-2 infection was included in this study. Patients were divided into two groups: patients who experienced breakthrough infection and those who were unvaccinated.

Survival and predictive factors in dialysis patients with COVID-19 in Japan: a nationwide cohort study.

Background: The Japanese Association of Dialysis Physicians, the Japanese Society for Dialysis Therapy, and the Japanese Society of Nephrology jointly established COVID-19 Task Force Committee and began surveying the number of newly infected patients.

Methods: This registry of the COVID-19 Task Force Committee was used to collect data of dialysis patients; a total of 1010 dialysis patients with COVID-19 were included in the analysis. Overall survival of patients was investigated with stratification by age group, complication status, and treatment.

Effect of 100 Hz electroacupuncture on salivary immunoglobulin A and the autonomic nervous system.

Background: A previous study has reported that low-frequency (LF) electroacupuncture (EA) influences salivary secretory immunoglobulin A (sIgA) and the autonomic nervous system (ANS). The ANS is known to control the secretion volume of sIgA; however, the effect of high-frequency (HF) EA on salivary sIgA has not been determined. We investigated whether HF EA affects salivary sIgA levels and the ANS.

Double cancer in different hepatic lobes: hepatocellular and cholangiocellular carcinoma.

Background/aim: Hepatic tumors with elements of both hepatocellular and cholangiocellular carcinoma are occasionally encountered; however, the independent and simultaneous occurrence of different epithelial malignant tumors in different lobes is rare. This is a case report of resected double cancer in different lobes of the liver.

Materials And Methods: A 73 year old Japanese man, with hepatic mass and a history of peritonitis and hepatitis, underwent laparotomy and hepatic resection of the posterior inferior and the left lateral segment, and cholecystectomy for cholecystlithiasis with left-sided gallbladder at our hospital in 1991.
