Characteristics of the 6th Japanese wave of COVID-19 in hemodialysis patients.

Background: We examined the clinical characteristics of hemodialysis patients with COVID-19 during the 6th wave of infection (mainly Omicron variant) in Japan.

Methods: Hemodialysis patients admitted in January 2022 and thereafter were grouped as the 6th wave group ( = 53), while others were grouped as the 1st-5th wave group ( = 47).

Results: The proportion of vaccinations was significantly higher in the 6th wave group than in the 1st-5th wave group (96.

Characteristics of hemodialysis patient with critical COVID-19.

Introduction: The clinical course of hemodialysis patients with COVID-19 still remains unclear.

Methods: Thirty-four hemodialysis patients were retrospectively enrolled. Patients were divided according to disease severity, and clinical symptoms and laboratory data at admission were compared.

Analysis of the cooked aroma and odorants that contribute to umami aftertaste of soy miso (Japanese soybean paste).

Soy miso, the traditional Japanese fermented soybean paste prepared using soybean koji, is used for imparting umami aftertaste to cooked dishes. The objective of this study was to identify the key odorants of cooked soy miso and their influence on umami aftertaste perception. Volatile compounds of soy miso and two rice misos were prepared using simultaneous distillation-extraction, and the key odorants were identified by using the gas chromatography-olfactometry/aroma extract dilution assay approach, and soy miso was compared with rice misos.

Seroprevalence of IgG1 and IgG4 class antibodies against Mycobacterium avium subsp. paratuberculosis in Japanese population.

Mycobacterium avium subsp. paratuberculosis (MAP) is the established causative agent of Johne's disease in cattle and other ruminants, and it has also been speculated to be a putative etiological agent of several human autoimmune diseases. It is acknowledged that dairy products deriving from infected animals play a role (could be vehicles) in exposing humans to MAP.

Characteristics of patients on hemodialysis therapy for more than 30 years.

Since its experimental introduction in 1960, hemodialysis has become a widely performed and relatively safe procedure. Therapeutic strategies have been developed, and the numbers of long-term survivors of hemodialysis therapy have been increasing. Hemodialysis therapy was introduced at Sangenjaya Hospital in October 1970, and the 16 patients who have survived for more than 30 years on hemodialysis therapy since its introduction at the hospital were enrolled in this study to investigate the characteristics of long-term hemodialysis patients.

Left ventricular hypertrophy is associated with arterial stiffness and vascular calcification in hemodialysis patients.

Left ventricular hypertrophy (LVH) is the most frequent cardiac abnormality in patients with end-stage renal disease (ESRD). Recent studies have shown that arterial stiffness is associated with mediacalcinosis in these patients. However, whether arterial stiffness and vascular calcification are associated with the LVH in patients with ESRD has not been well established.
