Effect of a Dynamic Exercise Program in Combination With Mediterranean Diet on Quality of Life in Women With Rheumatoid Arthritis.

OBJECTIVE: To assess the effect of a dynamic exercise program (DEP) in combination with a Mediterranean diet (MD) on health-related quality of life in women with rheumatoid arthritis (RA). METHOD: A randomized clinical trial including 144 women with RA diagnosis was performed. Patients were randomized into 4 groups: (1) MD + DEP (n = 36), (2) DEP (n = 37), (3) MD (n = 40), and (4) control (n = 31). All patients received conventional disease-modifying antirheumatic drugs. Health-related quality of life was assessed with 36-item Short Form Health Survey v2 (0-100 score) and disability with Health Assessment Questionnaire Disability Index at enrollment and after 24 weeks. Between-groups comparisons of the change in the quality of life scores from baseline to follow-up were performed using analysis of covariance in which baseline-to-follow-up was the dependent variable, and the intervention group was the independent variable. RESULTS: All patients had low disease activity at the time of enrollment, with a mean 28-joint Disease Activity Score of less than 3.2. Patients who were included in the MD + DEP and DEP groups showed 15 points of increase in health-related quality of life global punctuation versus 3.5 in the MD group and -4.6 in the control group (p = 0.01). Also the scores in the physical component after 24 weeks of intervention in the MD + DEP group improved (15.5), in the DEP group (12) and MD group as well (5.1), whereas the control group showed a decrease of the score (-1.7) (p = 0.03 between groups). CONCLUSIONS: The combination of MD + DEP could improve the quality of life in RA patients with low disease activity receiving conventional disease-modifying antirheumatic drugs.

Changes in body composition in heart failure patients after a resistance exercise program and branched chain amino acid supplementation.

BACKGROUND & AIMS: Heart Failure (HF) is a complex syndrome, which can include the physiological, neural hormonal and metabolic complications known as "Cardiac Cachexia" (CC). In the development of CC there is a release of catabolic cytokines (Tumor Necrosis Factor-α, interleukins 1 and 6) that cause a decrease of fat free mass and fat mass. These changes in body composition might be reversed with a therapeutic combination of resistance exercise and branched chain amino acid supplementation (BCAA). AIM: Evaluate changes in body composition after a resistance exercise program and BCAA supplementation in patients with HF. METHODS: In a randomized clinical trial with 3 month of follow-up anthropometric body composition analysis and stress tests were evaluated at the beginning and in the end of the study. Patients were divided into two groups; the experimental group performed the resistance exercise program and received 10 g/day BCAA supplementation, and the control group only performed the resistance exercise program. Both groups were provided with individualized diets and conventional medical treatment. RESULTS: Changes were found in hip circumference between the groups (p = 0.02), and muscle strength was increased in the experimental group (8%) and the control group (11.4%) with no difference between them. METS and VO2Max also increased in experimental and control groups (16.6% and 50.1% respectively). Regarding changes in symptoms, improvements in fatigue (45.4%), decubitus intolerance (21.8%) and dyspnea (25.4%) were observed in the overall sample. CONCLUSION: Improvements in physical and functional capacities are attributed to resistance exercise program but not to the BCAA supplementation. CLINICAL TRIALS IDENTIFIER: NCT02240511.
