The effects of respiratory muscle training on respiratory function and functional capacity in patients with early stroke: a meta-analysis.

Background: Respiratory muscle training is a continuous and standardized training of respiratory muscles, but the evidence of the effects on early stroke patients is not clear. This meta-analysis aimed to investigate the effects of respiratory muscle training on respiratory function and functional capacity in patients with early stroke.

Methods: PubMed, Embase, PEDro, ScienceDirect, AMED, CINAHL, and China National Knowledge Infrastructure databases were searched from inception to December 8, 2023 for articles about studies that 1) stroke patients with age ≥ 18 years old.

[Association of gender, age, education and polymorphism of DRD4 gene with cognitive functions in adults].

Objective: To assess the association of cognitive functions with gender, age, education and polymorphism of dopamine receptor D4 (DRD4) gene in healthy adults.

Methods: Four hundred and fifty-five healthy participants have completed 3 cognitive function tests including Tower of Hanoi (TOH), Wisconsin Card Sorting Test (WCST) and Trail Making Test (TMT). Peripheral blood samples were collected from all participants, and genomic DNA was extracted according to a standard phenol-chloroform procedure.
