The study was aimed to establish the effect of aerobic exercise on reflection index (RI), stiffness index (SI) and brachial finger pulse wave velocity (BFPWV) in healthy subjects of Bangalore, India. Students of 18 to 25 years (males) were recruited according to the inclusion criteria. The subjects were trained on treadmill for a period of 8 weeks, and the above parameters were measured using BIOPAC software and doppler machine. ANOVA of repeated measures was done to see the effect of training on RI, SI and BFPWV with bonferroni correction. There was a significant decrease in above parameters (P<0.0001) compared to basal levels. There was significant correlation between BFPWV and SI (P<0.001). 8 weeks of training showed beneficial effect by reducing BFPWV, SI, and RI and it returned towards baseline after subsequent 4 weeks of detraining. We conclude that changes are because of the effect of aerobic exercise and are reversible.

Effects of lifestyle activity level on anticipatory locomotor adjustments for pedestrian circumvention: an exploratory study.
Exp Brain Res
January 2025
School of Rehabilitation Sciences, Université Laval, Quebec, Canada.
Navigating public environments requires adjustments to one's walking patterns to avoid stationary and moving obstacles. It is known that physical inactivity induces alterations in motor capacities, but the impact of inactivity on anticipatory locomotor adjustments (ALA) has not been studied. The purpose of the present exploratory study was to compare ALAs and related muscle co-contraction during a pedestrian circumvention task between active (AA) and inactive young adults (IA).

Purpose: This updated systematic review and meta-analysis aims to evaluate the impact of a birthing ball (BB) exercises on low-risk parturients during labor, offering a more comprehensive understanding through a larger sample size, robust analysis, and focus on relevant endpoints that were underexplored in previous studies due to limited data.
Methods: We searched PubMed, Embase, Scopus, and Cochrane Central for randomized controlled trials (RCTs) comparing BB (also named Swiss ball) exercises with no intervention or standard care in parturients undergoing low-risk labor. Risk ratios (RR) and mean differences (MD) were calculated using a random-effects model.
Awareness of Contraindications Among Cancer Patients in Riyadh, Saudi Arabia: A Cross-Sectional Study.
Cancer Control
January 2025
Department of Pharmacy Practice, College of Pharmacy, AlMaarefa University, Dariyah, Riyadh, Saudi Arabia.
Introduction: Cancer patients often face challenges in managing their disease, particularly with regard to contraindications related to medications, foods, and physical activity, which can negatively affect treatment outcomes. This study aimed to evaluate cancer patients' awareness of these contraindications and to explore the influence of sociodemographic factors, support systems, comorbidities, and medication use on their knowledge.
Methods: A cross-sectional prospective study was conducted with 125 cancer patients in Saudi Arabia between December 2022 and February 2023.
Therapeutic potential of ketone bodies on exercise intolerance in heart failure: looking beyond the heart.
Cardiovasc Res
January 2025
Cardiovascular Research Centre, University of Alberta, Edmonton, Alberta, Canada.
Recent evidence suggests that ketone bodies have therapeutic potential in many cardiovascular diseases including heart failure (HF). Accordingly, this has led to multiple clinical trials that use ketone esters to treat HF patients, which we term ketone therapy. Ketone esters, specifically ketone monoesters, are synthetic compounds which, when consumed, are de-esterified into two β-hydroxybutyrate (βOHB) molecules and increase the circulating βOHB concentration.
