Article Abstract
Objective: The objective of this study is to (a) examine racial/ethnic differences in trajectories of cognitive function and (b) evaluate the role of education and health behaviors (physical activity [PA] and smoking) as mediators of racial/ethnic differences in the rate of decline in cognitive function in older adults.
Method: Data for this study came from the Health and Retirement Study ( n = 3,424). Hierarchical linear models were used to define the trajectory of cognitive function between 2002 and 2008. Participants were classified based on PA as non-vigorously active, intermittent vigorously active, and consistently vigorously active.
Results: After adding education, the Hispanic's and Black's disparities in cognitive performance were slightly attenuated (Hispanics, β = -1.049, p < .001; Blacks, β = -3.397, p < .001) but were still different from Whites. Smoking was not associated with the cognition intercept or rate of decline.
Discussion: We found education had a partial mediating effect on racial differences in levels of cognition but not on the rate of change over time.

Background: Alzheimer's disease (AD) patients and animal models exhibit an altered gut microbiome that is associated with pathological changes in the brain. Intestinal miRNA enters bacteria and regulates bacterial metabolism and proliferation. This study aimed to investigate whether the manipulation of miRNA could alter the gut microbiome and AD pathologies.

Sensorimotor impairments potentially have a negative impact on participation. However, comprehensive understanding of sensorimotor recovery and participation in survivors of critical illness is limited.

Objectives/background: Prior studies have claimed that people engage in compulsive buying in an attempt to deal with stress. Nonetheless, not every stressed person engages in compulsive buying. It is therefore important to investigate the cognitive mechanisms underlying such behavior.

With the persistence of difficult employment, a large number of college students feel anxious and nervous about job hunting. College students with different family economic status have various feelings and performances when faced with employment, possibly due to subjective social class differences. The present study investigated the employment confidence of 611 undergraduates in Chongqing, aimed to ascertain the overall employment confidence of Chinese college students, and tried to analyze how subjective social class works on the employment confidence of college students and its influencing mechanism.

Background: Post-viral syndromes, including long- and post-COVID, often lead to persistent symptoms such as fatigue and dyspnoea, affecting patients' daily lives and ability to work. The COVI-Care M-V trial examines whether interprofessional, patient-centred teleconsultations, initiated by general practitioners in cooperation with specialists, can help reduce symptom burden and improve care for patients.
Methods: To evaluate the effectiveness of the intervention under routine care conditions, a cluster-randomised controlled trial is being conducted.
