The potential impact of a specific physical activity program on biomechanical gait parameters and neuromuscular strategies around the ankle joint in older adults with sarcopenic obesity (SO) remains largely unexplored. The objective of this study was to investigate the effectiveness of a 24-week posture, strengthening, and motricity (PSM) program on improving neuromuscular strategies and biomechanical gait parameters in older adults with SO. 40 participants were randomly assigned to either the trained group (TG) and the control group (CG). Only the TG received the PSM program. Standardized evaluations were performed before and after the intervention, including walking tests on an instrumented gait analysis treadmill to evaluate biomechanical gait parameters and EMG activity of ankle muscles. After the PSM program, TG exhibited an increase in comfortable walking speed (+80%, < 0.001) and step length (+38%, < 0.05). Moreover, TG demonstrated a reduction in CoP velocity (-26%, < 0.01). These gait modifications were associated with decreased muscle activity during the different gait phases ( < 0.05). The PSM program effectively improved gait and neuromuscular capacities in older adults with SO. Notably, these results shed light on the remarkable trainability of neuromuscular capacities in older adults with SO, despite the adverse effects of aging and obesity.

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.

Background And Purpose: Throwing a baseball involves intense exposure of the arm to high speeds and powerful forces, which contributes to an increasing prevalence of arm injuries among athletes. Traditional rigid exoskeletons and rehabilitation equipment frequently lack portability, safety, ergonomic design, and affordability. Traditional rehabilitation approaches frequently require therapist monitoring, resulting in therapy delays.

Background: Lamotrigine clearance can change drastically in pregnant women with epilepsy (PWWE) making it difficult to assess the need for dosing adjustments. Our objective was to characterize lamotrigine pharmacokinetics in PWWE during pregnancy and postpartum along with a control group of nonpregnant women with epilepsy (NPWWE).
Methods: The Maternal Outcomes and Neurodevelopmental Effects of Antiepileptic Drugs (MONEAD) study was a prospective, observational, 20 site, cohort study conducted in the United States (December 2012 and February 2016).

The study found a significant causal relationship between coffee intake and obsessive-compulsive disorder, showing a negative correlation. There was no causal relationship between coffee intake and other mental disorders. The sensitivity analysis test found no pleiotropy affecting the results, and no single nucleotide polymorphism had a major impact on the robustness of the results, indicating that the results are stable and reliable.

Objective: To investigate the relationship between maternal age and nutritional status, and test associations between maternal nutritional status and child mortality with a focus on maternal obesity.
Design: Secondary analysis of data from nationally representative cross-sectional sample of women of reproductive ages (15-49 years) and their children under five years. The outcome variable for maternal nutritional status was Body Mass Index (BMI), classified into underweight (BMI < 18.
