Cognition, physical function and life purpose in the rural elderly population: a systematic review.

Introduction: Aging in rural areas is challenging and has very specific characteristics in the way these elderly people live their old age, from the perspectives of cognition, functionality and life purpose. There is a lack of information and data in the literature on how people age in rural areas around the world. The aim of this study was to identify and describe how people age in rural areas, focusing on the following domains: cognition, physical function/functionality and life purpose.

Twelve weeks of exercise training improves cognitive status, physical performance and quality of life in Alzheimer's disease: A systematic review and meta-analysis.

Alzheimer's disease (AD) is a progressive neurodegenerative disorder in which there is slow and gradual impairment of mental function. Considering the increase in cases due to population aging, the potential benefits of physical training in AD are of great importance and need further elucidation. This study aims to identify the impact of physical training on crucial aspects of AD such as cognitive status, physical performances, quality of life and activities of daily living.

Exercise performance effect of central dopamine is mediated by hypothalamic neuronal activation.

Acting centrally, dopamine has been shown to induce ergogenic effects derived from its influence on thermoregulation, motivation, reward, and motor control. Thus, to evaluate the role of the central dopaminergic system in hypothalamic neuronal activation and its relationship with exercise performance, Wistar rats were intracerebroventricularly injected with saline (SAL) or SCH-23390 (SCH, dopamine D1 receptor blocker) at rest and before timed submaximal exercise (∼13 min) or exercise until fatigue. Core body and tail temperatures were recorded throughout the exercise.

Adapting a mobile TB screening unit to provide integrated screening services and linkage to primary care.

Objective: We adapted a mobile TB screening unit to create an integrated screening program for noncommunicable diseases and TB, using community health worker (CHW) navigators to support linkage to care. We piloted the model in underserved communities of Lima, Peru, evaluating its feasibility, acceptability, and ability to continue supporting TB case detection.

Design: The program provided screening for TB, hypertension, diabetes, and depression and was rebranded to avoid TB-associated stigma.

Glycosylation of chrysin with β-d-glucose tetraacetate (LQFM280) enhances its in vitro and in vivo neuroprotective effects against the toxicity induced by 3-nitropropionic acid.

Chrysin (CHR) is a naturally occurring flavonoid found in the human diet, recognized for its potential in preventing neurodegenerative diseases. However, its limited water solubility restricts its bioavailability and therapeutic applications. To address this issue and bolster the neuroprotective properties of CHR for potential nutraceutical or medicinal use, we investigated a novel compound, LQFM280, formed by conjugating CHR with β-d-glucose tetraacetate.
