Objective: This study investigated the effects of dual-task resistance training (RT) and detraining on physical function, cognitive capacity, lipid profile, renal function, oxidative stress markers, and chronic inflammation of institutionalized older adults.
Methods: The study involved 11 older adults (83.09 ± 8.1 years) residing in a long-term care institution, spanning 42 weeks with assessments at weeks 1, 14-15, 28, and 42. The initial 12 weeks following the first assessment (weeks 2-13) served as a pre-control, during which participants maintained their routine activities. A dual-task resistance training protocol was implemented from weeks 16 to 27, followed by a detraining period from weeks 29 to 41. Assessments included clinical characteristics, physical function, cognitive ability, blood samples for biochemical parameters, oxidative stress, and chronic inflammation.
Results: Dual-task RT significantly enhanced balance (p = 0.027) and 4 m walking speed (p = 0.027) post-training compared to the pre-control. It also decreased the completion time for the sit-and-stand test both post-training (p = 0.008) and post-detraining (p = 0.015) relative to pre-control. Cognitive ability showed significant improvements (p < 0.05). The CAT/TBARS ratio increased significantly post-training (p < 0.001) and remained elevated post-detraining. Nitric Oxide levels increased post-training (p < 0.05) and stayed higher post-detraining. The IL-10/TNF-α ratio significantly increased post-training (p < 0.05).
Conclusion: Dual-task RT performed over 12 weeks improved physical function, cognitive capacity, muscular strength, oxidative stress markers, and chronic inflammation in institutionalized older adults. Furthermore, these benefits were sustained even after a period of detraining.

Executive functions (EF) affect child competencies across domains in early childhood. Thus, this study examined: 1) the EF differences between young children with global developmental delays (GDD) and those with typical development (TD); 2) the relationship between mastery motivation (MM) and EF; 3) the association between developmental abilities and EF in both groups. Participants included 26 mother-child dyads of preschoolers with GDD (age 24-55 months) and 26 sex- and mental-age-matched dyads of TD preschoolers (age 15-29 months).

Knee osteoarthritis contributes substantially to worldwide disability. Post-traumatic osteoarthritis (PTOA) develops secondary to joint injury, such as ligament rupture, and there is increasing evidence suggesting a key role for inflammation in the aetiology of PTOA and associated functional deficits. Colony stimulating factor 1 receptor (CSF1-R) has been implicated in the pathogenesis of musculoskeletal degeneration following anterior cruciate ligament (ACL) injury.

Monitoring health is one of the basic principles of Occupational Health and Safety. The main objective of this monitoring will be the detection of possible damage to health arising from work. They try to discover the effects that the inherent risks with the work may cause the worker, which will show, given the case, through an alteration of health or the state of organic and functional state, both physically and mentally.
