Induces Two Types of Dendritic Cell Activation and Effectively Suppresses Onset of the Common Cold: A Randomized, Double-Blind, Placebo-Controlled Trial.

Background/objectives: GCL1815 is a lactic acid bacterium thought to activate dendritic cells. This randomized, placebo-controlled, double-blind study aimed to evaluate the effects of GCL1815 on human dendritic cells and the onset of the common cold.

Methods: Two hundred participants were divided into two groups and took capsules containing either six billion GCL1815 cells or placebo for 8 weeks.

Screening of novel lactic acid bacteria with high induction of IgA production, dendritic cell activation, and IL-12 production.

In this study, we screened 308 lactic acid bacteria strains for high immunoglobulin A (IgA) production, dendritic cell activation, and IL-12 production using human derived cells. Among them, Lactobacillus helveticus GCL1815 demonstrated superior performance in all aspects, indicating its remarkable potential for immunomodulatory functions in both innate and adaptive immunity.

Life Course Epidemiology of Hip Osteoarthritis in Japan: A Multicenter, Cross-Sectional Study.

Background: The incidence of developmental dysplasia of the hip (DDH) in Japanese newborns has reduced drastically following a primary prevention campaign initiated around 1972 to 1973; this perinatal education campaign promoted maintaining the hips of newborns in the naturally flexed-leg position. The purpose of the present study was to describe the life course epidemiology of hip osteoarthritis (OA) in adolescent and adult patients and to assess its association with exposure to the primary prevention campaign for DDH.

Methods: We included new patients with hip OA diagnosed from January 1, 2022, to December 31, 2022, at 12 core hospitals (8 special-function hospitals and 4 regional medical care support hospitals).

Association of Postexercise Vagal Dysfunction With Protein-Energy Wasting and Noncardiovascular Outcomes in Patients Receiving Hemodialysis: A Retrospective Cohort Study.

Objective: Postexercise vagal dysfunction is linked to noncardiovascular mortality in hemodialysis patients, but the mechanism is unknown. This study aimed to determine the association of cardiovagal neuropathy with systemic inflammation, protein-energy wasting, and noncardiovascular hospitalization.

Methods: This 2-center retrospective cohort study analyzed data from 280 hemodialysis patients who underwent exercise test.

Effect of Continuous Ingestion of Bifidobacteria and Dietary Fiber on Improvement in Cognitive Function: A Randomized, Double-Blind, Placebo-Controlled Trial.

subsp. GCL2505 has been shown to have some positive effects on health, including improved defecation frequency and reduced visceral fat. These effects are thought to be due to GCL2505's unique ability to reach the intestine in a viable form and proliferate after a single intake.
