The study aimed to compare the effectiveness of a traditional cardiac rehabilitation (CR) program with an enhanced program incorporating the model of therapeutic engagement (MTE) and extended remote support for patients undergoing coronary artery bypass graft (CABG) patients. In a randomized controlled trial, 88 CABG patients were assigned to experimental and control groups. The experimental group received integrated MTE cardiac rehabilitation, and assessments were conducted at three time points: pre-CR, one month later, and three months post-CR. The study measured medication adherence (MARS-5) and sense of coherence (SoC-13) scales. The study found no significant differences in demographic factors between the experimental and control groups. However, significant differences were observed in MARS and individuals' SoC scores over time in the experimental group, with notable improvements (p < 0.001). The control group showed significant changes only up to one month. Group effects were evident, with consistent increases in the experimental group's outcomes at each assessment point. Integrating the MTE into CR programs offers benefits in terms of medication adherence and individuals' sense of coherence, which warrants further investigation and clinical implementation. Cardiac rehabilitation (CR) is recognized as one of the most effective interventions for secondary prevention, but its accessibility is limited in middle-income countries (MICs). This study represents one of the first theoretically-informed CR trials in a MIC that incorporates the model of therapeutic engagement (MTE) combined with extended remote support services into CR program. The MTE model, as a theoretical framework, was highly suitable for CR settings and demonstrated favorable outcomes. This approach has the potential to greatly benefit cardiac patients, particularly those who may initially show hesitance or reluctance towards engaging in CR. [ABSTRACT FROM AUTHOR]

Oxidative stress is implicated in the pathogenesis of osteoarthritis. Curcuminoids are natural polyphenols with strong antioxidant capacity and may thus be helpful in the treatment of osteoarthritis. The present randomized double-blind placebo-controlled trial investigated the efficacy of curcuminoids in reducing systemic oxidative burden in patients suffering from knee osteoarthritis. Forty patients with mild-to-moderate primary knee osteoarthritis were given curcuminoid capsules (1500 mg/day in 3 divided doses; n = 19) or matched placebo capsules (n = 21) for a period of 6 weeks. Curcuminoids were co-administered with piperine (15 mg/day) in order to improve the bioavailability. Serum activities of superoxide dismutase (SOD) and concentrations of reduced glutathione (GSH) and malonedialdehyde (MDA) were determined spectrophotometrically at baseline and at the end of the treatment period in both groups. Serum activities of SOD as well as GSH and MDA concentrations were comparable between the study groups at baseline (p > 0.05). There was a significant elevation in serum SOD activities (mean change: 2.94 ± 3.73 vs. −0.38 ± 1.33; p < 0.001), a borderline significant elevation in GSH concentrations (mean change: 1.39 ± 2.78 vs. −0.02 ± 1.62; p = 0.064) and a significant reduction in MDA concentrations (mean change: −5.26 ± 4.46 vs. −2.49 ± 3.81; p = 0.044) in the curcuminoids compared with the placebo group. Changes in serum activities of SOD and concentrations of GSH and MDA during the course of trial were significantly correlated. Short-term supplementation with curcuminoids attenuates systemic oxidative stress in patients with osteoarthritis. These antioxidant effects may account for the reported therapeutic effects of curcuminoids in relieving osteoarthritis symptoms. [ABSTRACT FROM AUTHOR]
