AI Article Synopsis
- The study aims to explore the relationship between physical activity and cognitive function among older adults in Mexico and South Korea, highlighting the growing concern of cognitive impairment as populations age.
- Utilizing data from two surveys, the research involved participants over 50 years of age and assessed physical activity and cognitive function using specific tests.
- Results indicated that while 40.68% of participants in Mexico reported physical activity, a significant protective link between physical activity and cognitive function was found only in the Korean older adults, suggesting differing impacts based on location.
Article Abstract
Introduction: As the world's population ages, the prevalence of cognitive impairment associated with age increases. This increase is particularly pronounced in Asia and South-America. The objective of this study was to investigate separately the longitudinal association of physical activity and cognitive function in; older adults in Mexico and South Korea.
Materials And Methods: This is a secondary analysis of two surveys, The Mexican Health and aging Study (MHAS) (n = 5853) and Korean Longitudinal Study of aging (KLoSA) (n = 5188), designed to study the aging process of older adults living in Mexico and South Korea. Participants older than 50 years were selected from rural and urban areas achieving a representative sample. Physical activity was assessed using self-report. Cognition was assessed using Cross-Cultural Cognitive Examination (CCCE) and Minimental state examination (MMSE) in Mexico and South Korea respectively. Here we investigate the longitudinal association between physical activity and cognition during 3 years for MHAS and 4 years for KLoSA using multiple linear regression analyses.
Results: The prevalence of physical activity was 40.68 % in MHAS and 35.57 % in KLoSA. In the adjusted longitudinal multivariate analysis, an independent association was found between physical activity and MMSE score OR 0.0866 (CI 0.0266-0.1467 p-value 0.0047) in the Korean older adults, while there was no significant association in MHAS.
Conclusions: Physical activity could have a protective effect on the cognitive decline associated with aging in the Korean population.

Aim: To develop pH (pHe)-triggered membrane adhesive nanoliposome (pHTANL) of CD40a to enhance anti-tumor activity in pancreatic cancer while reducing systemic toxicity.
Materials And Methods: A small library of nanoliposomes (NL) with various lipid compositions were synthesized to prepare pH (pHe)-triggered membrane adhesive nanoliposome (pHTANL). Physical and functional characterization of pHTANL-CD40a was performed via dynamic light scattering (DLS), Transmission Electron Microscopy (TEM), confocal microscopy, and flow cytometry.

Background: Chronic obstructive pulmonary disease (COPD) induces an imbalance in T helper (Th) 17/regulatory T (Treg) cells that contributes to of the dysregulation of inflammation. Exercise training can modulate the immune response in healthy subjects.
Objective: We aimed to evaluate the effects of exercise training on Th17/Treg responses and the differentiation of Treg phenotypes in individuals with COPD.

We aimed to determine the persisting effects of various exercise modalities and intensities on functional capacity after periods of training cessation in older adults. A comprehensive search was conducted across the Cochrane Library, PubMed/MEDLINE, Scopus, and Web of Science Core Collection up to March 2024 for randomized controlled trials examining residual effects of physical exercise on functional capacity in older adults ≥ 60 years. The analysis encompassed 15 studies and 21 intervention arms, involving 787 participants.

Large-scale gene-environment interaction (GxE) discovery efforts often involve analytical compromises for the sake of data harmonization and statistical power. Refinement of exposures, covariates, outcomes, and population subsets may be helpful to establish often-elusive replication and evaluate potential clinical utility. Here, we used additional datasets, an expanded set of statistical models, and interrogation of lipoprotein metabolism via nuclear magnetic resonance (NMR)-based lipoprotein subfractions to refine a previously discovered GxE modifying the relationship between physical activity (PA) and HDL-cholesterol (HDL-C).

Rationale: Obesity is an increasing medical issue not responding well to behavioural treatments beyond their initial weeks/months.
Aims And Objectives: Before suggesting surgical or pharmacological interventions, medical professionals might consider referrals to cost-effective, community-based behavioural treatments if stronger theoretical/empirical bases were demonstrated. Thus, evaluation of such is warranted.
