Health Education Programme Through Physical Exercise for People With Severe Mental Disorders

Fundación para la Investigación del Hospital Clínico de Valencia29 enrolled

Overview

The goal of this clinical trial is to \[learn about, test, compare etc.\] in individuals with severe mental disorders and obesity comorbid. The main question\[s\] it aims to answer are: * Are inflammatory activity, oxidative and vascular damage and metabolic mechanisms, as well as neurocognitive and functional performance, related to different physical exercise interventions? * Do inflammatory, oxidative stress and cardiometabolic biomarkers predict neurocognitive improvement after physical activity training? Participants will guided-exercise of moderate intensity and frecuency, and incentive of autonomous physical activity proposals by the specialist; guided physical activity group (GPAG), or (b) 12 weeks of an exercise program standard physical activity without guided and incentives; standard physical activity group (SPAG). If there is a comparison group: Researchers will compare GPAG and SPAG to see if inflammatory, oxidative stress, and cardio-metabolic biomarkers improve neurocognitive performance after physical activity training

The psychiatric disorders and obesity comorbidity is related to neurocognitive impairment and inflammation. Exercise is crucial to improve and maintain healthy lifestyles. This randomized controlled trial tested the efficacy of aerobic exercise as promoter of neurocognitive improvement across psychiatric disorders and OB comorbid. Participants (n=29) received brief healthy lifestyle counseling and were randomized to 12 weeks of guided-exercise of moderate intensity and frequency, and incentive of autonomous physical activity proposals by the specialist; guided physical activity group (GPAG) (n=10) or 12 weeks of exercise standard physical activity without guided and incentives; standard physical activity group (SPAG) (n=19). Peripheral blood biomarkers of inflammation, oxidative stress, vascular mechanisms and metabolic activity, as well as neurocognitive and functional performance were assessed twice over after and before treatment. Mixed one-way analysis of variance and linear regression analyses were performed.

Guided physical activityBEHAVIORAL

To achieve the European guidelines of 150 minutes by week of moderate intensity physical activity, participants randomized to the GPAG condition were prescribed three 60 minutes exercise sessions (five minutes of warm-up and five minutes of cool-down for a total of sixty minutes per session) per week for 12 weeks. Exercise consisted of brisk walking in urban and rural open spaces during which heart rate monitors were worn and participants were instructed to stay within their moderate intensity range. The incentives were different proposals for specific exercises to train the different musculoskeletal areas more comprehensively. Autonomous exercise was monitored offside the sessions through a series of weekly checkpoints.

Standard physical activityBEHAVIORAL

Participants randomised to the SPAG performed their usual daily activities and continued with their daily routine. Both conditions were matched for duration of physical activity. Participants in both conditions were required to attend three on-site sessions by week over 12 weeks that served as checkpoints. Moreover, both conditions were provided with brief healthy lifestyle counseling at baseline.

Inflammatory markers

Serum cytokine concentrations were determined using Luminex® X-MAP technology (Luminex Corp., Austin, TX, USA) based on flow cytometry. Sample processing and data analysis were performed according to the manufacturer's instructions. (Behring Nephelometer II, Dade Behring, Inc., Newark, DE, USA)..

Time frame: 4 months

Oxidative stress markers

Oxidative stress in leukocytes was evaluated using fluorimetry techniques with a fluoroscan (Synergy MX). In total, 100 000 cells were plated in each well of 96-well plates and incubated for 30 min at 37 °C with the corresponding fluorochromes, as follows: dichlorofluorescein diacetate to measure reactive oxygen species (ROS) production (485 nm excitation, 535 nm emission), MitoSOX to measure mitochondrial ROS (mROS) (510 nm excitation, 580 nm emission), tetramethylrodamin methyl ester to assess mitochondrial membrane potential (552 nm excitation, 574 nm emission), nonylacridin orange mitochondrial mass (495 nm excitation, 519 nm emission), and 5-chloromethylfluorescein diacetate to measure intracellular glutathione (492 nm excitation, 517 nm emission). The monocyte cell line U-937 was used as an internal control to avoid potential fluctuations in fluorescence over time.

Time frame: 4 months

Adhesion molecules markers

Serum lipid peroxidation levels were measured using a commercial thiobarbituric acid reactive substances (TBARS) kit according to the manufacturer's instructions (Olympus, Hamburg, Germany). A Luminex 200 flow analyzer system (Austin, TX, USA) was employed to analyze adhesion molecules in serum. To measure immunological markers, citrated blood samples were incubated with dextran (3%) for 45 min to isolate human polymorphonuclear leukocytes (PMNs). The supernatant was layered over Ficoll-Hypaque (GE Healthcare, Barcelona, Spain) and centrifuged for 25 min at room temperature at 650g. Lysis buffer was added to the remaining erythrocytes in the pellet, which were incubated at room temperature for 5 min and then spun at 240g for 5 min. PMNs were rinsed twice and resuspended at 37 ℃ in Hanks' balanced salt solution (Sigma Aldrich, MO). Scepter 2.0 cell counters (Millipore, MA, USA) was employed to count cells
