Abstract
COVID-19 is an infectious disease caused by the SARS-CoV-2 virus, which induces a high release of pro-inflammatory chemokines and cytokines, leading to severe systemic disorders. Further, evidence has shown that recovered COVID-19 patients still have some symptoms and disorders from COVID-19. Physical exercise can have many health benefits. It is known to be a potent regulator of the immune system, which includes frequency, intensity, duration, and supervised by a professional. Given the confinement and social isolation or hospitalization of COVID-19 patients, the population became sedentary or opted for physical exercise at home, assuming the guarantee of the beneficial effects of physical exercise and reducing exposure to SARS-CoV-2. This study aimed to investigate the effects of a supervised exercise protocol and a home-based unsupervised exercise protocol on chemokine and cytokine serum levels in recovered COVID-19 patients. This study was a prospective, parallel, two-arm clinical trial. Twenty-four patients who had moderate to severe COVID-19 concluded the intervention protocols of this study. Participants were submitted to either supervised exercise protocol at the Clinical Hospital of the Federal University of Pernambuco or home-based unsupervised exercise for 12 weeks. We analyzed serum levels of chemokines (CXCL8/IL-8, CCL5/RANTES, CXCL9/MIG, CCL2/MCP-1, and CXCL10/IP-10) and cytokines (IL-2, IL-4, IL-6, IL-10, IL-17A, TNF-α, and IFN-γ). Before the interventions, no significant differences were observed in the serum levels of chemokines and cytokines between the supervised and home-based unsupervised exercise groups. The CXCL8/IL-8 (p = 0.04), CCL2/MCP-1 (p = 0.03), and IFN-γ (p = 0.004) levels decreased after 12 weeks of supervised exercise. In parallel, an increase in IL-2 (p = 0.02), IL-6 (p = 0.03), IL-4 (p = 0.006), and IL-10 (p = 0.04) was observed after the supervised protocol compared to pre-intervention levels. No significant differences in all the chemokines and cytokines were found after 12 weeks of the home-based unsupervised exercise protocol. Given the results, the present study observed that supervised exercise was able to modulate the immune response in individuals with post-COVID-19, suggesting that supervised exercise can mitigate the inflammatory process associated with COVID-19 and its disorders.

Abstract
Although physical activity (PA) improves the physical, mental, and social outcomes of people living with HIV (PLH), multiple barriers prevent them from exercising. In this systematic review, we investigated the effect of home-based interventions to promote physical activity (HBI) among PLH. Randomised trials and quasi-experimental studies published in English until March 2020 were sought in five databases. Independent reviewers performed data extraction, risk of bias assessment and pragmatic-explanatory (PRECIS-2) evaluation of study characteristics. Outcomes included engagement in PA, body composition, cardiorespiratory fitness, strength, metabolic disturbances, and quality of life (QoL). Out of 480 retrieved references, six studies met inclusion criteria. Interventions lasted 12-48 weeks and involved 400 individuals (57.8% women). Ninety-eight (24.5%) participants completed interventions, but dropout rates varied considerably (5.0-54.5%). Resulted showed increased PA (two studies) and improved cardiorespiratory fitness or strength (three and two studies, respectively). Four studies demonstrated reduction of waist circumference and increase in lean body mass. QoL improved in two of three studies. We conclude HBI (aerobic and/or resistance exercises) may contribute to improve PA and/or cardiorespiratory fitness, body composition, strength and QoL of PLH. Further investigation using multi-centre standardised protocols is warranted to provide stronger evidence of their effectiveness in health promotion for PLH.

Impact of exercise training on symptoms of depression, physical activity level and social participation in people living with HIV/AIDS: a systematic review and meta-analysis. BMC Infect Dis 2022; 22:469. [PMID: 35578192 PMCID: PMC9109396 DOI: 10.1186/s12879-022-07145-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 02/10/2022] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Symptoms of depression are prevalent in people living with human immune deficiency virus/acquired immune deficiency syndrome (PLWHA), and worsened by lack of physical activity/exercises, leading to restriction in social participation/functioning. This raises the question: what is the extent to which physical exercise training affected, symptoms of depression, physical activity level (PAL) and social participation in PLWHA compared to other forms of intervention, usual care, or no treatment controls? METHOD Eight databases were searched up to July 2020, according to the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) protocol. Only randomised controlled trials involving adults who were either on HAART/HAART-naïve and reported in the English language, were included. Two independent reviewers determined the eligibility of the studies, extracted data, assessed their quality, and risk of bias using the Physiotherapy Evidence Database (PEDro) tool. Standardised mean difference (SMD) was used as summary statistics for the mean primary outcome (symptoms of depression) and secondary outcomes (PAL and social participation) since different measuring tools/units were used across the included studies. Summary estimates of effects were determined using a random-effects model (I2). RESULTS Thirteen studies met the inclusion criteria with 779 participants (n = 596 participants at study completion) randomised into the study groups, comprising 378 males, 310 females and 91 participants with undisclosed gender, and with an age range of 18-86 years. Across the studies, aerobic or aerobic plus resistance exercises were performed 2-3 times/week, at 40-60 min/session, and for between 6-24 weeks, and the risk of bias vary from high to low. Comparing the intervention to control groups showed significant difference in the symptoms of depression (SMD = - 0.74, 95% confidence interval (CI) - 1.01, - 0.48, p ≤ 0.0002; I2 = 47%; 5 studies; 205 participants) unlike PAL (SMD = 0.98, 95% CI - 0.25, 2.17, p = 0.11; I2 = 82%; 2 studies; 62 participants) and social participation (SMD = 0.04, 95% CI - 0.65, 0.73, p = 0.91; I2 = 90%; 6 studies; 373 participants). CONCLUSION Physical exercise training could have an antidepressant-like effect in PLWHA but did not affect PAL and social participation. However, the high heterogeneity in the included studies, implies that adequately powered randomised controlled trials with clinical/methodological similarity are required in future studies.

Abstract
OBJECTIVE Exercise is a recommended component of care for people living with HIV/AIDS; however, it is unclear which type of exercise is most effective. The purpose of this study was to investigate the relative effects of different types of exercise interventions on aerobic capacity measured by peak oxygen consumption (peak VO2) and health-related quality of life (HRQoL) in this population. METHODS For this systematic review and indirect-comparisons meta-analysis (network meta-analysis), different electronic databases were searched up to February 2020 for randomized controlled trials that evaluated the effects of different types of exercise interventions on peak VO2 and HRQoL of people living with HIV/AIDS. Mean differences, standardized mean difference (SMD), and 95% CI were calculated. Fixed- and random-effects Bayesian network meta-analysis were used to compare the relative effectiveness of the different exercise interventions. RESULTS Forty studies met the study criteria, reporting on a total of 1518 patients. When comparing the exercise interventions with usual care (control group) for the peak VO2 outcome, combined aerobic and resistance exercise was the highest ranked exercise intervention with an SMD of 4.2 (95% CI = 2.5 to 5.9), followed by aerobic exercise (SMD = 3.1; 95% CI = 1.4 to 5.1). Compared with aerobic exercise, resistance training, and yoga, combined aerobic and resistance exercise was the best exercise intervention to promote improvement on physical function, general health, mental health, and energy/vitality domains HRQoL. CONCLUSION The combined aerobic and resistance exercise was the highest ranked exercise intervention to improve peak VO2 and HRQoL. Combined aerobic and resistance exercise should be considered as a component of care for people living with HIV/AIDS.

Abstract
ABSTRACT The latest recommendations for HIV therapeutic management emphasize the importance of regular physical activity (PA). This cross-sectional study assessed the self-reported level of PA, amount of leisure time PA (LTPA), and the predictors of PA practiced in 257 people living with HIV (PLWH) in Burundi. The World Health Organization recommends 150 min of PA per week. In our study, 80.2% of the participants met this recommendation. Participants were more engaged in PA at work (436.8 ± 682.1 min/week) compared with leisure time (231.7 ± 383.8 min/week) and transportation (235.9 ± 496.5 min/week). Multivariate analysis revealed that men (β = -101.65; p = .01) who were white-collar workers (β = 67.21; p < .03) with higher education level (β = 274.21; p < .001) reported higher levels of LTPA than other groups. Integrating PA counseling into the routine care and implementing community-based exercise programs could enhance participation in PA in PLWH.

Abstract
Background Regular physical activity is the prime modality for the prevention of numerous non-communicable diseases and has also been advocated for resilience against COVID-19 and other infectious diseases. However, there is currently no systematic and quantitative evidence synthesis of the association between physical activity and the strength of the immune system. Objective To examine the association between habitual physical activity and (1) the risk of community-acquired infectious disease, (2) laboratory‐assessed immune parameters, and (3) immune response to vaccination. Methods We conducted a systemic review and meta-analysis according to PRISMA guidelines. We searched seven databases (MEDLINE, Embase, Cochrane CENTRAL, Web of Science, CINAHL, PsycINFO, and SportDiscus) up to April 2020 for randomised controlled trials and prospective observational studies were included if they compared groups of adults with different levels of physical activity and reported immune system cell count, the concentration of antibody, risk of clinically diagnosed infections, risk of hospitalisation and mortality due to infectious disease. Studies involving elite athletes were excluded. The quality of the selected studies was critically examined following the Cochrane guidelines using ROB2 and ROBINS_E. Data were pooled using an inverse variance random-effects model. Results Higher level of habitual physical activity is associated with a 31% risk reduction (hazard ratio 0.69, 95% CI 0.61–0.78, 6 studies, N = 557,487 individuals) of community-acquired infectious disease and 37% risk reduction (hazard ratio 0.64, 95% CI 0.59–0.70, 4 studies, N = 422,813 individuals) of infectious disease mortality. Physical activity interventions resulted in increased CD4 cell counts (32 cells/µL, 95% CI 7–56 cells/µL, 24 studies, N = 1112 individuals) and salivary immunoglobulin IgA concentration (standardised mean difference 0.756, 95% CI 0.146–1.365, 7 studies, N = 435 individuals) and decreased neutrophil counts (704 cells/µL, 95% CI 68–1340, 6 studies, N = 704 individuals) compared to controls. Antibody concentration after vaccination is higher with an adjunct physical activity programme (standardised mean difference 0.142, 95% CI 0.021–0.262, 6 studies, N = 497 individuals). Conclusion Regular, moderate to vigorous physical activity is associated with reduced risk of community-acquired infectious diseases and infectious disease mortality, enhances the first line of defence of the immune system, and increases the potency of vaccination. Protocol registration The original protocol was prospectively registered with PROSPERO (CRD42020178825).

Abstract
INTRODUCTION There is a positive association between exercise and improved mental health in the general population. Although there is a greater burden of psychological distress among lesbian, gay, and bisexual (LGB) people, little is known about the association between exercise and mental health in this population. The authors explored the association between exercise and poor mental health reported by LGB adults in the United States. METHODS Our analyses used data from the 2017 Behavioral Risk Factor Surveillance System survey. Multiple regression analyses were used to determine the association between exercising and mental health days adjusting for sociodemographic characteristics. RESULTS Data were available for 6371 LGB participants. LGB adults who participated in any exercise reported almost 1.0 day less of poor mental health in the past 30 days compared with LGB adults who did not exercise (P ≤ .01). LGB adults who met one or both of the physical activity guidelines had between 1.2 and 1.7 days less of poor mental health compared with those who did not meet the guidelines (P ≤ .01). CONCLUSION Fewer days of poor mental health were reported by LGB adults who exercised. Determining whether physical activity interventions, including aerobic and strengthening exercises, could improve mental health outcomes in LGB adults should be studied.

Abstract
The purpose of this study was to assess the effect of training modality and exercise intensity on the modulation of lymphocytes CD4 count in people living with HIV (PLWH). A search for randomised controlled trials was performed using five databases (PubMed/Medline, Cochrane, LILACS, Scielo and CAPES). Meta-analyses of mean differences (MD) were conducted using a random-effects model to compare the effects of training modality and intensity on CD4 count. The CD4 count comparing physical training vs. control group (MD of CD4 was 54.58 cell/ml³ [CI 95% 15.58-93.59], p =< 0.01). In according to the subgroup analysis, only aerobic exercise has proved to have a significant effect on CD4 (MD 79.91 cell/ml³ [CI 95% 19.30-140.52], p =< 0.01). When exercise intensities were stratified, only intense training proved to have a significant effect on CD4 (MD 64.87 cell/ml³ [CI 95% 15.79-113.95], p =< 0.01). In meta-regression analysis showed that the aerobic training, as well, high the intensity training were predictors significant to the improvement of CD4 (p =< 0.01). Exercise training is an important strategy to assist in the treatment of PLWH. The aerobic training modality and the high intensity training were able to promote improve the modulation of CD4 count chronically in PLWH.

Abstract
OBJECTIVES Comprehensive care for people living with human immunodeficiency virus (HIV) (PLH) includes the promotion of healthier habits, including physical activity (PA). This study aimed to describe a multicomponent pragmatic trial protocol to assess the effect of PA in preventing body changes and metabolic disturbances, improving the quality of life of PLH starting antiretroviral therapy (ART) and present cohort characteristics. METHODS PLH undergoing ART for ≤4 months were recruited for a randomized trial. The intervention comprised three cardiorespiratory and/or strength training sessions per week at the clinic or in public spaces for 6 months under on-site or remote supervision, and educational sessions. Participants' PA levels, cardiorespiratory fitness, anthropometric measures, strength, flexibility, quality of life, and laboratory monitoring (blood glucose and lipids, CD4 counts) at baseline and post-intervention will be compared. The pragmatic design aims to enable the assessment of intervention effectiveness in real-life conditions. RESULTS At baseline, our cohort of 38 recently diagnosed patients (mean time since HIV diagnosis and duration of ART were 3 and 2.58 months, respectively) were predominantly male, young, with high schooling and good immune status (median CD4 count=498 cells/mm3). Twenty-two (57.9%) patients reported a PA below the World Health Organization recommendations. We found baseline normal anthropometric measures and metabolic parameters: below-average trunk flexion and elbow extension strength, poor handgrip strength and flexibility, and high quality of life scores in all except the physical domain. CONCLUSIONS Understanding how effective PA is in preventing body changes and metabolic disturbances, and in improving the quality of PLH starting ART may help establish guidelines to better incorporate PA in HIV care.

Abstract
The Medical Outcome Study-HIV Health Survey (MOS-HIV) is one of the most used questionnaires for the evaluation of the health-related quality of life (HRQoL) in people living with HIV (PLWHIV) in both medical settings and research studies. This study aimed to estimate the average reliability of the MOS-HIV scores and to evaluate the characteristics of the studies that could explain the variability between reliability estimates. Furthermore, the study aimed to estimate the induction rate of the reliability of the MOS-HIV. A systematic review of the previous literature, including studies that reported α and/or test-retest coefficients with the data at hand for the total score of the MOS-HIV and the subscales, was conducted. Fifty studies (52 samples; N = 14,132) were included in the reliability generalization meta-analysis. The average α coefficient for the total score of MOS-HIV was .91 and above .80 for all of the subscales, except for role functioning, which had an average coefficient of .76. Different study dimensions were related to the heterogeneity of reliability between studies. Reliability induction was found to be 76.1%. The results obtained in the present study indicate that the MOS-HIV is a reliable instrument for HRQoL evaluation in PLWHIV, for clinical and research purposes. In the clinical practice of health services, nurses could employ this gold standard for reliable evaluations of HRQoL in PLWHIV.

Abstract
(1) Background: People with HIV (PWH) may perform more than one type of exercise cumulatively. The objective of this study is to investigate recreational exercise and its association with health-related quality of life (HRQOL) and comorbidities in relation to potential covariates. (2) Methods: The HIBES study (HIV-Begleiterkrankungen-Sport) is a cross-sectional study for people with HIV. The differences between non-exercisers versus exercisers (cumulated vs. single type of exercises) were investigated using regression models based on 454 participants. (3) Results: Exercisers showed a higher HRQOL score compared to non-exercisers (Wilcox r = 0.2 to 0.239). Psychological disorders were identified as the main covariate. Participants performing exercise cumulatively showed higher scores in duration, frequency, and intensity when compared to participants performing only one type of exercise. The mental health summary score was higher for the cumulated and single type of exercise if a psychological disorder existed. Duration and intensity were associated with an increase of HRQOL, whilst a stronger association between psychological disorders and exercise variables were evident. Exercise duration (minutes) showed a significant effect on QOL (standardized beta = 0.1) and for participants with psychological disorders (standardized beta = 0.3), respectively. (4) Conclusions: Psychological disorders and other covariates have a prominent effect on HRQOL and its association with exercise. For PWH with a psychological disorder, a stronger relationship between HRQOL with exercise duration and intensity emerged. However, differentiation of high-HRQOL individuals warrants further investigation by considering additional factors.

Abstract
People living with HIV (PLWH) have limited exercise capacity because of anemia, neuromuscular disorders, and pulmonary limitations. We used a meta-analysis to examine the effect of aerobic and resistance exercise alone and in combination on cardiovascular parameters. Subgroup meta-analyses were conducted and long-term effects of exercise were investigated. A systematic literature search was conducted up to July/August 2017. The Physiotherapy Evidence Database-scale was used to rate quality and assess the risk of bias on the papers. Standardized mean differences (SMDs) were calculated to assess the effect of exercise. Posttreatment comparison between the exercise and control groups revealed moderate and large effect sizes in favor of the intervention group for VO2max (SMD = 0.66, p < .0001) and the 6-minute walk test (SMD = 1.11, p = .0001). Exercise had a positive effect on cardiovascular parameters in PLWH. Exercise can be a prevention factor for PLWH dealing with multiple comorbidities.

Abstract
Pharmacologic advancements in the treatment of human immunodeficiency virus (HIV) has extended the life expectancy of people living with HIV (PLWH). An unfortunate side effect of HIV treatment, however, is an increased prevalence of dyslipidemia, glycemic dysregulation and abnormal distribution of body fat (lipodystrophy). Consequently, the risk of developing cardiovascular disease (CVD) is significantly increased in PLWH and ultimately a major cause of mortality. Physical activity and exercise training are interventions that have effectively protected against the development of CVD and, in the presence of CVD, has help mitigate morbidity and mortality. Early concerns over potential immunosuppressive effects of exercise in PLWH have largely been dispelled and in some cases exercise has been shown to strengthen markers of immune function. Interventions with aerobic exercise, resistance exercise, and their combination, particularly at higher intensities, are showing promising health outcomes in PLWH. This review will summarize the key cardiovascular and metabolic effects of antiretroviral therapy; the effects of the types and intensities of exercise on cardiorespiratory fitness, cardiometabolic markers, and muscle strength; and provide recommendations on strategies to apply exercise interventions in clinical settings.

Abstract
INTRODUCTION To our knowledge, there are no systematic review study with meta-analysis that investigated the influence of training variables on specific outcomes (CD4 cell counts) addressed aerobic training (AT) for HIV+ patients. In this sense, the purpose of this study was to perform a systematic review with meta-analysis of randomized controlled trials on AT in HIV+ patients and to analyze the influence of AT modulating variables on the CD4 cells, VO2max, and metabolic parameters. EVIDENCE ACQUISITION Searches were performed in the databases PubMed, ISI Web of Knowledge, SportDiscus, Lilacs, Science Direct, and Scielo. EVIDENCE SYNTHESIS Twelve studies involving 438 subjects (78.2% male) were included. Overall, the sample was sedentary (pre-training VO2max of 30.5 mL.kg-1.min-1) with a mean time of virus infection of 66.9 months and mean number of CD4 cells of 467.8 cells/mm3. AT increased the VO2max (ES=1050 [0.455 to 1.64]; P<0.001) and CD4 cell count (ES=0.402 [0.203 to 0.601]; P<0.001). AT for 8-12 weeks appears to be sufficient to increase VO2max, and the highest gains are associated with patients who present higher initial CD4 cell values. There was no difference to metabolic parameters. CONCLUSIONS AT did not change the metabolic parameters, but it was AT is able to promote a greater magnitude of improvement in VO2max in the initial weeks of training and a greater increase in the number of CD4 cells in patients who present a better immune condition prior to training.

Abstract
OBJECTIVE The purpose of this systematic review and meta-analysis was to examine the effects of exercise on depression and anxiety in people living with HIV (PLWH), and to evaluate, through subgroup analysis, the effects of exercise type, frequency, supervision by exercise professionals, study quality, and control group conditions on these outcomes. METHOD A literature search was conducted through four electronic databases from inception to February 2019. Considered for inclusion were randomized controlled trials (RCTs) investigating exercise interventions and depression or anxiety as outcomes in people living with HIV (≥ 18 years of age). Ten studies were included (n = 479 participants, 49.67% females at baseline), and the standardized mean difference (SMD) and heterogeneity were calculated using random-effect models. An additional pre-post meta-analysis was also conducted. RESULTS A large effect in favor of exercise when compared to controls was found for depression (SMD = -0.84, 95%CI = [-1.57, -0.11], p = 0.02) and anxiety (SMD = -1.23, 95%CI = [-2.42, -0.04], p = 0.04). Subgroup analyses for depression revealed large effects on depression for aerobic exercise only (SMD = -0.96, 95%CI = [-1.63, -0.30], p = 0.004), a frequency of ≥3 exercise sessions per week (SMD = -1.39, 95%CI = [-2.24, -0.54], p < 0.001), professionally supervised exercise (SMD = -1.40, 95%CI = [-2.46, -0.17], p = 0.03]), and high-quality studies (SMD = -1.31, 95%CI = [-2.46, -0.17], p = 0.02). CONCLUSION Exercise seems to decrease depressive symptoms and anxiety in PLWH, but other larger and high-quality studies are needed to verify these effects.

Evaluating the Feasibility and Impact of a Yoga Intervention on Cognition, Physical Function, Physical Activity, and Affective Outcomes in People Living With HIV: Protocol for a Randomized Pilot Trial. JMIR Res Protoc 2019; 8:e13818. [PMID: 31115343 PMCID: PMC6547772 DOI: 10.2196/13818] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Revised: 04/16/2019] [Accepted: 04/16/2019] [Indexed: 12/19/2022] Open
Abstract
Background Despite lower mortality rates due to combination antiretroviral therapy, people living with HIV (PLWH) are grappling with increasingly complex health issues, including cognitive impairments in areas such as memory, attention, processing speed, and motor function. Yoga has been shown to be an effective form of exercise and mindfulness-based stress reduction for many clinical populations. However, no randomized trials have evaluated the impact of yoga on cognitive and physical function among PLWH. Objective The aim of this pilot randomized trial was to determine the feasibility of a yoga intervention to lay the groundwork for a full-scale, multisite, community-based trial for PLWH. Specific objectives are to (1) assess the feasibility of study protocol and procedures, (2) compare cognition in the yoga group with the usual care control group after 12 weeks of the intervention in PLWH, and (3) compare the effects of the 12-week yoga intervention versus control on balance, walking speed, physical activity, mental health, medication adherence, and quality of life among PLWH. Methods We propose a pilot randomized trial with 2 parallel groups (yoga versus control). We will recruit 25 PLWH (>35 years) from community and health organizations in Halifax, Canada. After baseline assessment with blinded assessors, participants will be randomly assigned to the yoga or control group, using a random computer generator. Participants in the yoga group will engage in supervised 60-min group-based yoga sessions 3 times a week for 12 weeks at a yoga studio. Participants in the control group will maintain their current physical activity levels throughout the study. Results As per the Consolidated Standards of Reporting Trials extension for pilot studies, means of all outcomes, mean change, and 95% CIs will be calculated for each group separately. Two-tailed independent t tests and Fisher exact tests will be used to compare groups at baseline. We will analyze quantitative postintervention questionnaire responses using Chi-square tests, and open-ended responses will be analyzed thematically. Intention-to-treat and per-protocol analyses will be used to analyze secondary variables. Changes in outcome variables will be examined between groups and within groups. Effect sizes will be reported for each outcome. A priori adherence and satisfaction criteria will be met if participants attend >70% of the yoga sessions and if >70% of the participants are satisfied with the intervention as determined by a postparticipation questionnaire. Study enrollment began in January 2018, with results expected for October 2019. Conclusions This pilot randomized trial will be the first to investigate the feasibility and effect of a yoga intervention on cognitive and physical outcomes among PLWH. This work will inform the feasibility of further investigations in terms of capacity building, participant recruitment and retention, and assessment and intervention protocols.

Impact of physical exercises on immune function, bone mineral density, and quality of life in people living with HIV/AIDS: a systematic review with meta-analysis. BMC Infect Dis 2019; 19:340. [PMID: 31014262 PMCID: PMC6480814 DOI: 10.1186/s12879-019-3916-4] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2017] [Accepted: 03/18/2019] [Indexed: 01/08/2023] Open
Abstract
BACKGROUND Compromised immune function, associated with human immune deficiency virus(HIV) infection, is improved by antiretroviral therapy(ART) which also decreases bone mineral density(BMD), and possibly the quality of life(QoL). However, physical(aerobic/resistance) exercises, were reported to induce reverse effects in uninfected individuals and were appraised in the literature for evidence of similar benefits in people living with HIV/AIDS(PLWHA). The main study objective was to evaluate the impact of physical (aerobic and resistance) exercises on CD4+ count, BMD and QoL in PLWHA. METHODS A systematic review was conducted using the Cochrane Collaboration protocol. Searching databases, up to June 2017, only randomized control trials investigating the effects of either aerobic, resistance or a combination of both exercise types with a control/other intervention(s) for a period of at least 4 weeks among adults living with HIV, were included. Two independent reviewers determined the eligibility of the studies. Data were extracted and risk of bias(ROB) was assessed with the Cochrane Collaboration ROB tool. Meta-analyses were conducted using random effect models using the Review Manager(RevMan) computer software. RESULTS Nineteen studies met inclusion criteria(n = 491 participants at study completion) comprising male and female with age range 22-66 years. Two meta-analyses across 13 sub-group comparisons were performed. However, there were no RCTs on the impact of physical exercises on BMD in PLWHA. The result showed no significant change in CD4+ count unlike a significant effect of 5.04 point(95%CI:-8.49,-3.74,p = 0.00001) for role activity limitation due to physical health(QoL sub-domain). Overall, the GRADE evidence for this review was of moderate quality. CONCLUSIONS There was evidence that engaging in moderate intensity aerobic exercises (55-85% Maximum heart rate-MHR), for 30-60 min, two to five times/week for 6-24 weeks significantly improves role activity limitation due to physical health problems, otherwise physical(aerobic or/and resistance) exercises have no significant effects on CD4+ count and other domains of QoL. Also, there is lack of evidence on the impact of exercises on BMD in PLWHA due to the paucity of RCTs. The moderate grade evidence for this review suggests that further research may likely have an important impact on our confidence in the estimate of effects and may change the estimate.

Abstract
Physical activity (PA) combats the effects of multimorbidity and antiretroviral therapy in people living with HIV (PLWH), but PLWH often don't meet recommended PA guidelines. The purpose of our review was to investigate whether supervised PA improved functional capacity in PLWH. Preferred Reporting Items for Systematic Reviews and Meta-Analyses were followed. Five databases were searched for randomized controlled trials in English, with participants ages 18 years and older, and a supervised PA intervention. A database search yielded 8,267 articles, with 15 eligible for review inclusion. We found a low risk of bias within and across studies. Combined aerobic/progressive resistance training (PRT) improved strength, cardiovascular, and flexibility outcomes; aerobic interventions alone showed no significant improvements; PRT improved strength outcomes; yoga or yoga/meditation showed no outcome differences; and t'ai chi showed cardiovascular and flexibility improvements. We found that supervised PA increased functional capacity in PLWH and that self-report was not a reliable assessment.

Abstract
BACKGROUND/OBJECTIVE There are conflicting results regarding the effects of exercise on immune function of HIV positive patients. Exercise can also be beneficial to psychological functioning of the patients. The purpose of this study was to determine the impact of a 12-week aerobic and resistance exercise training program on mental health and CD4 counts among female HIV+ patients. METHODS This clinical trial was conducted between September and December 2013. Forty participants (women age range 20-40) were carefully selected from 240 HIV-positive women referred to Voluntary Counseling and Treatment Center (VCT) and randomly assigned to either exercise (80 min of aerobic and strength training while receiving the VCT's routine services) group (n = 20) or control (received the VCT's routine services only) group (n = 20). To assess their mental health status, all participants completed GHQ28 questionnaire. Blood samples were collected to measure CD4 and T-cell counts at baseline and at the end of the 12-week intervention. RESULTS From a sample of 40 women with HIV infection, the data of 30 participants [experimental group (14) and control group (16)] were analyzed (participation rate 75%). The results indicated that after the intervention program, a significant difference in CD4 cell counts was found between the two groups (P = 0.01). With regard to mental health, after performing intervention, significant improvement in all subscales including anxiety disorder, social function, depression and mental health's total score was observed in the exercise compared to the control groups (P < 0.001). CONCLUSION Exercise training can be included in health care services in order to improve the mental health status of women with HIV infection. No effect on CD4 count was detected.

Abstract
BACKGROUND Home-based care is used in many countries to increase quality of life and limit hospital stay, particularly where public health services are overburdened. Home-based care objectives for HIV/AIDS can include medical care, delivery of antiretroviral treatment and psychosocial support. This review assesses the effects of home-based nursing on morbidity in people infected with HIV/AIDS. METHODS The trials studied are in HIV positive adults and children, regardless of sex or setting and all randomised controlled. Home-based care provided by qualified nurses was compared with hospital or health-facility based treatment. The following electronic databases were searched from January 1980 to March 2015: AIDSearch, CINAHL, Cochrane Register of Controlled Trials, EMBASE, MEDLINE and PsycINFO/LIT, with an updated search in November 2016. Two authors independently screened titles and abstracts from the electronic search based on the study design, interventions and types of participant. For all selected abstracts, full text articles were obtained. The final study selection was determined with use of an eligibility form. Data extraction was performed independently from assessment of risk of bias. The results were analysed by narrative synthesis, in order to be able to obtain relevant effect measures plus 95% confidence intervals. RESULTS Seven studies met the inclusion criteria. The trial size varied from 37 to 238 participants. Only one trial was conducted in children. Five studies were conducted in the USA and two in China. Four studies looked at home-based adherence support and the rest at providing home-based psychosocial support. Reported adherence to antiretroviral drugs improved with nurse-led home-based care but did not affect viral load. Psychiatric nurse support in those with existing mental health conditions improved mental health and depressive symptoms. Home-based psychological support impacted on HIV stigma, worry and physical functioning and in certain cases depressive symptoms. CONCLUSIONS Nurse-led home-based interventions could help adherence to antiretroviral therapy and improve mental health. Further larger scale studies are needed, looking in more detail at improving medical care for HIV, especially related to screening and management of opportunistic infections and co-morbidities.

Abstract
Objective Mental illness is highly prevalent among people living with HIV. Poor mental health is linked to HIV disease progression, making the treatment of mental illness alongside HIV essential. While the benefits of exercise on the physical health of people living with HIV are well established, the effect of exercise on mental health in this population is less examined. Therefore, this study aimed to conduct a systematic literature review of the effects of exercise on mental health in people living with HIV. Methods A search of electronic databases (PubMed, Web of Science, PsycINFO) through 30 November 2016 was completed. The methodological framework for scoping studies was used to conduct the review process. RISMA guidelines were used to report the results. Results The search resulted in 2273 articles and 52 were determined to be relevant. After review of the full text of potentially relevant studies, 24 studies were included for the analysis. Discussion Both aerobic and resistance exercise have independent and combined positive effects on various indicators of mental health in people living with HIV. Major limitations include high attrition rate, small sample size, and poor study designs. Higher quality studies with more diverse populations such as women, older adults, and transgender individuals are required.

Abstract
Background Improved treatment options of HIV have resulted in regular physical activities of many HIV-infected patients. However, data on effects of sports in HIV-patients are scarce. Methods 21 HIV-infected persons were monitored prospectively while preparing for a marathon run. Multiple parameters with regard to immunology, quality of life and metabolism were measured at 4 time points (at baseline 1 year before the marathon run, 3 and 6 months after beginning of training, and immediately before marathon). Results 13 out of 21 participants completed the marathon (12 male, 1 female; median age 42 years [27–50]; CD4 = 620/μl [146–1268]; 11 were on ART since 3.5 years [1–7]). 8 participants ceased training early. All reasons for stopping (besides one pre-existing metatarsal fracture) were not regarded as training-related (e.g. time limitation n = 3; newly diagnosed anal cancer n = 1; personal reasons/unknown n = 3). We observed a significant increase in absolute CD4-T-cells (620/μl [146–1268] vs. 745 [207–1647]; p = 0.001) with simultaneous decrease of CD4-T-cell apoptosis (53% [47–64] vs. 32% [14–42]); p < 0.01). No effects on viral load independent of ART occurred. Systolic blood pressure and cholesterol improved significantly, although moderate and normal at baseline (cholesterol 185 mg/dl [98–250] vs. 167 [106–222], p = 0.02; RRsys 125 mmHg [100–145] vs. 120 [100–140], p = 0.01). Blood count, liver enzymes, creatinine and CK remained unchanged. Conclusions The results of this pilot study indicated improved metabolic and immunologic parameters in HIV-infected patients undergoing moderate endurance training. Although training effects or ART cannot be ultimately separated as underlying mechanisms, we conclude that marathon training is safe for HIV-infected patients and potentially improves general health. Trial registration DRKS00011592 (retrospectively registered on February 9th 2017).

Abstract
Physical exercise (PE) has not been well studied in persons living with HIV (PLHIV). We conducted an overview of systematic reviews to assess the effectiveness of PE and to determine the most appropriate PE regimen for PLHIV. We used the CDC's Prevention Research Synthesis Project's database and manual searches to identify systematic reviews published between 1996 and 2013. We qualitatively synthesized the findings from five reviews to assess the effectiveness of PE and conducted meta-analyses on CD4 counts to identify the best PE regimen. PE is associated with reduced adiposity and depression, but was not associated with a decrease in HIV viral load. CD4 counts were improved by interventions with interval aerobic or 41-50 minutes of exercise three times per week compared with other modes and duration of exercise. PE appears to benefit PLHIV, but more research is needed to help develop appropriate PE strategies specifically for PLHIV.

Abstract
The aim of this paper is to use a scoping review to investigate the extent, range, and nature of research on rehabilitation interventions for adults living with HIV. Electronic databases (MEDLINE, EMBASE, CINAHL, AMED, and PsychINFO) and reference lists of the included articles were searched. Authors were emailed when possible for unavailable articles. A total of 897 titles and abstracts were retrieved. Thirty-three articles were included. There were 27 different rehabilitation interventions delivered by 18 professions. The studies were completed in four different countries. Most studies were published in 2008. A randomized-controlled trial was the most used method. The nature of the studies was analyzed according to the three-core concepts of the International Classification of Functioning, Disability and Health: 28 studies addressed impairments; six studies addressed activity limitations; and 14 studies addressed participation restrictions. This scoping study advances the knowledge of research on rehabilitation interventions for adults living with HIV. More research on rehabilitation interventions is needed in sub-Saharan Africa and other low-income and middle-income countries to ensure that these individuals are receiving the best possible care. There is a need for the HIV field to recognize the important contribution of rehabilitation toward the HIV care continuum.

Abstract
Home-based rehabilitation (HBR) has been shown to improve the lives of people living with a wide range of chronic diseases in resource-rich settings. This may also be a particularly effective strategy in resource-poor settings, where access to institution-based rehabilitation is limited. This review aimed to summarise and discuss the evidence related to the effectiveness of home-based rehabilitation (HBR) interventions designed specifically for adults living with HIV. A scoping review methodology was employed, involving systematic search techniques and appraisal of appropriate evidence. English-language journal articles that assessed the quality of life or functional ability outcomes of HBR interventions for adults living with HIV were considered for this review. Out of an initial 1 135 publications retrieved from the search of databases, six articles met this review's inclusion criteria. While this review highlights the scarcity of empirical evidence related to HBR interventions for adults living with HIV, the findings of these six articles are that HBR is a safe management option that may confer a number of physical and psychological benefits for this population. Future research on HBR interventions should include a wider range of assessment measures, including cost-benefit analyses and specific tools designed to assess the functional ability and participation in activities of daily living of participants involved in these programmes. In particular, more research on HBR is required in resource-poor environments, such as sub-Saharan Africa where HIV is endemic, to assess whether this is a feasible strategy that is both effective and practical in the areas that may need it most.

Abstract
Cardiorespiratory fitness (CRF) is a modifiable risk factor for cardiovascular disease and premature mortality. CRF levels and moderators among people living with HIV (PLWH) are unknown. The aim of the current meta-analysis was to (1) determine mean CRF in PLWH and compare levels with age- and gender-matched healthy controls (HCs), (2) explore moderators of CRF, (3) and (4) explore moderators of CRF outcomes following physical activity (PA) interventions. Major electronic databases were searched systematically for articles reporting CRF expressed as maximum or peak oxygen uptake (ml/min/kg) in PLWH. A random effects meta-analysis calculating the pooled mean CRF including subgroup- and meta-regression analyses was undertaken. Across 21 eligible studies, the CRF level was 26.4ml/kg/min (95% CI=24.6 to 28.1) (n=1010; mean age=41years). There were insufficient data to compare CRF levels with HCs. A higher body mass index (β=-0.99, 95% CI=-1.93 to -0.06, P=0.04), older age (β=-0.31, 95% CI=-0.58 to -0.04, P=0.02) and the presence of lipodystrophy (β=-4.63, 95% CI=-7.88 to -1.39, P=0.005) were significant moderators of lower CRF levels. Higher CD4+ counts (β=0.004, 95% CI=0.0007 to 0.007, P=0.016), supervised interventions (P<0.001) and interventions with a lower frequency of weekly sessions (2 or 3 versus 4 times) (P<0.001) predicted a better CRF-outcome following PA. CRF levels of PLWH are among the lowest in comparison to other vulnerable populations. More research on the most optimal physical activity intervention characteristics is needed.

Abstract
A randomized controlled trial was conducted to investigate the effects of a 16-week home-based rehabilitation (HBR) intervention on the quality of life, functional mobility, and functional capacity of adult people living with HIV (PLWH) on antiretroviral therapy in KwaZulu-Natal, South Africa. The intervention was carried out by community health care workers under the supervision of a qualified physical therapist. Participants in the control group received the standard of care as well as written health advice. While participants in the intervention group showed greater improvements across all outcome measures, between-group differences were nonsignificant. HBR for PLWH is a safe means of addressing the functional deficits experienced by PLWH and appears likely to improve quality of life. A task-shifting approach may be a feasible method of meeting the varied needs of PLWH, while at the same time potentially minimizing costs to already overburdened health care systems.

Abstract
BACKGROUND People with HIV are living longer with the health-related consequences of HIV, multi-morbidity, and aging. Exercise is a key strategy that may improve or sustain health for people living with HIV. Our aim was to examine the safety and effectiveness of aerobic exercise interventions on immunological, virological, cardiorespiratory, strength, weight, body composition, and psychological outcomes in adults living with HIV. METHODS We conducted a systematic review using the Cochrane Collaboration protocol. We searched databases up to April 2013. We included randomized controlled trials comparing aerobic exercise with no exercise or another intervention performed at least three times per week for at least four weeks among adults living with HIV. Two reviewers independently determined study eligibility. Data were extracted from studies that met inclusion criteria using standardized forms. We assessed risk of bias using the Cochrane Collaboration's tool for assessing risk of bias. Outcomes were analyzed as continuous and meta-analyses conducted using random effects models with Review Manager (RevMan) computer software. RESULTS Twenty-four studies met inclusion criteria (n = 936 participants at study completion); the majority of participants were men (73 %) and the majority were taking antiretroviral therapy (19/24 included studies). The exercise intervention included aerobic exercise alone (11 studies) or a combination of aerobic and resistive exercise (13 studies) ranging from 5 to 52 weeks. Fifty-eight meta-analyses were performed. Main results indicated statistically significant improvements in selected outcomes of cardiorespiratory status (maximum oxygen consumption, exercise time), strength (chest press, knee flexion), body composition (lean body mass, percent body fat, leg muscle area), depression symptoms, and quality of life (SF-36 questionnaire) among exercisers compared with non-exercisers. No significant differences in change in CD4 count and viral load were found. CONCLUSIONS Performing aerobic exercise or a combination of aerobic and resistive exercise at least three times per week for at least five weeks is safe and can lead to improvements in cardiorespiratory fitness, strength, body composition and quality of life for adults with HIV. Aerobic exercise is safe and beneficial for adults living with HIV who are medically stable.

Abstract
Background In the era of highly active antiretroviral therapy HIV is now viewed as a chronic disease. Although people living with HIV are living longer lives, they are prone to a number of disabilities. Home-based rehabilitation has been shown to be an effective means of improving quality of life and function for people with a wide range of chronic diseases. There is a dearth of evidence, however, related to home-based rehabilitation interventions for people living with HIV, particularly in sub-Saharan Africa — the region with the highest global prevalence of HIV. Methods A randomised controlled trial design will be employed. Adults living with HIV who have been on antiretroviral therapy for at least six months and with defined limited mobility will be randomly allocated to either an intervention group or the control group. Pre and post-intervention testing will be conducted at a public hospital in KwaZulu-Natal, South Africa in order to assess the participants’ quality of life, perceived level of disability, functional ability and endurance. Individuals randomly allocated to the intervention group will participate in a four-month home-based rehabilitation programme, conducted once a week in their homes. This programme will be implemented by community workers who will be trained and supervised by a qualified physiotherapist. The participants in the control group will continue with the standard clinic management offered to them. On completion of the intervention, all participants will be re-assessed using the same outcome measures. Analysis of results will be carried out on intention-to-treat basis in order to identify any changes between intervention and control groups. Discussion The researchers aim to employ a novel task shifting approach to implement a needs-based home-based rehabilitation programme for people living with HIV in order to improve their quality of life and functional ability. It is hoped that this study will provide rehabilitation professionals and researchers with evidence that can be utilised to improve existing rehabilitation interventions for people living with HIV.

The aim of this study was to evaluate and compare the effect of two types of exercises interventions on the regularity and health-related physical fitness in HIV-infected individuals who use antiretroviral therapy (ART). A total of 53 HIV+ African women (mean age=39.5±8.4 years) on ART participated in the study. Subjects were randomly divided into 3 groups, namely, formal exercise (FEG), playful exercise (PEG) and control (CG). During 12 weeks, the exercise groups underwent a program of 1-hour duration with a frequency of 3 times a week. The FEG performed a protocol that included 20 minutes of exercise, cycling at 60 % of V̇O2peak, increasing to 75 % and 85 % in the 4th and 8th weeks, respectively, and a muscular endurance circuit consisted of 6 exercises at 15 repetitions per minute (RM). The PEG followed a program consisting of active games. Before and after the intervention the participants were submitted to a clinical evaluation including immunological parameters (CD4+), cardiovascular risk factors, physical fitness and anthropometry. Comparison of somatic variables before and after the program showed no exercise effect. Immunological and cardiovascular variables were also independent of the exercise group. The main effect was found in cardiorespiratory fitness: exercise groups increased significantly in V̇O2peak (FEG=14.7 %; PEG=11.1 %) with no significant differences in CG. The percentage of high attendance was identical between the two groups. It was concluded that there is no contraindication for exercise in this type of population and the beneficial effect was mainly in cardiorespiratory fitness, regardless of the type of exercise performed.

Effects of a 2-Year Supervised Exercise Program Upon the Body Composition and Muscular Performance of HIV-Infected Patients. Open AIDS J 2015; 9:80-8. [PMID: 26587076 PMCID: PMC4645897 DOI: 10.2174/1874613601509010080] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2015] [Revised: 08/08/2015] [Accepted: 08/16/2015] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND There is a lack of research investigating long-term effects of exercise training upon the body composition and muscle function in HIV-infected patients (PHIV). The study investigated the influence of a 2-year supervised exercise program on body composition and strength of PHIV under highly active antiretroviral therapy (HAART). METHODS A training program including aerobic, strength and flexibility exercises was performed by 27 PHIV (17 men/ 10 women; age: 48.7±7.0 years; HAART: 150.7±65.3 months) during 1 year and 18 PHIV (10 men/ 8 women; age: 50.6±5.2 years; HAART: 176.6±53.1 months) during 2 years. Body composition and knee isokinetic strength were assessed at baseline and at the end of each year of intervention. RESULTS Body composition remained stable along the whole experiment vs baseline (1-year - total muscle mass: Δ men=1.1%, P=0.21; Δ women=1.4%, P=0.06; trunk fat: Δ men=-0.1%, P=0.65; Δ women=-1.5%, P=0.45; 2 years - total muscle mass: Δ men=2.7%, P=0.54; Δ women=-1.9%, P=0.71; trunk fat: Δ men=4.4%, P=0.96; Δ women=10.0%, P=0.30). After 1-year, peak torque increased in men (Δ extension=4.2%, P=0.01; Δ flexion=12.2%, P=0.04) and total work reduced in women (Δ extension=-15.4%, P=0.01, Δ flexion=-17.5%, P=0.05). All strength markers remained stable vs baseline after 2 years of intervention (P>0.05). Only men showed significant reduction in the risk of disability due to sarcopenia (P=0.05) after 1 year of intervention, which remained stable after 2 years. CONCLUSION Long-term exercise training preserved strength and muscle mass in PHIV under HAART. Exercise programs should be part of HIV therapy to prevent sarcopenia of this population along the years. TRIAL REGISTRATION ACTRN12610000683033; UTN U1111-1116-4416.

Abstract
Human immunodeficiency virus (HIV) has infected > 60 million people since its discovery and 30 million people have died since the pandemic began. Antiretroviral therapy has transformed HIV infection from an acute to a chronic disease, increasing life expectancy but also adding to the potential side effects associated with drug therapy and the comorbidity accompanying longevity. Exercise can play a valuable role in the management of HIV/AIDS patients by addressing various symptoms and improving their quality of life, but the optimum mode, intensity, frequency, and duration of exercise that take the different clinical stages of the disease into consideration are inadequately known. Searches of Medline, Embase, Science Citation Index, CINAHL database, HealthSTAR, PsycINFO, Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, Physiotherapy Evidence Database (PEDro), and SPORTDiscus were conducted between 2000 and January 2014. Searches of published and unpublished abstracts were conducted, as well as a hand search of reference lists and tables of contents of relevant journals and books. Identified studies were reviewed for methodological quality. A total of 33 studies met the inclusion criteria. Most studies failed to indicate the optimum type (mode), intensity, frequency, and duration of aerobic and progressive resistive exercise prescribed to HIV-infected individuals in relation to the different clinical stages of the disease. The purpose of this review is to provide evidence-based recommendations after revision of exercise guidelines for HIV patients, by highlighting practical guidelines that clinical exercise therapists should consider when prescribing exercise for patients in different stages of the disease.

Abstract
People living with HIV (PLWH) are living longer and are at greater risk for chronic comorbidities (e.g., cardiovascular disease, cancer) compared to those not living with HIV. Regular, sustained exercise can prevent and/or mitigate the severity of these comorbidities. Our purpose was to describe patterns of planned exercise implemented in the home setting (i.e., free-living exercise) in PLWH by gender and age. PLWH (n = 102) completed a sociodemographic survey and a 7-day exercise diary documenting daily exercise duration, frequency, and intensity. Women exercised an average of 2.4 (interquartile range [IQR] 0.5-6.0) hours per week compared to men, who exercised 3.5 (IQR 0.5-7.5) hours per week (p = .18). This relationship was particularly evident during middle adulthood for women versus for men (p = .05). PLWH exercised regularly but at less than recommended levels. This is among the first evidence describing free-living exercise patterns of PLWH.

Abstract
In India in 2009, it was estimated that 2.4 million people were living with HIV, which equates to a prevalence of 0.3 percent. While this seems low, because India’s population is so large, this rate is third in the world in terms of the absolute number of people living with HIV/AIDS. This study evaluated the self-esteem and quality of life of people living with HIV/AIDS in the Indian population using a correlational design. A significant positive correlation between self esteem and the different dimensions of quality of life was established. Interventions designed for people with HIV/AIDS could well include self esteem as a moderator of quality of life.

Abstract
Several studies have reported the benefits of exercise training for adults with HIV, although there is no consensus regarding the most efficient modalities. The aim of this study was to determine the effects of different types of exercise on physiologic and functional measurements in patients with HIV using a systematic strategy for searching randomized controlled trials. The sources used in this review were the Cochrane Library, EMBASE, MEDLINE, and PEDro from 1950 to August 2012. We selected randomized controlled trials examining the effects of exercise on body composition, muscle strength, aerobic capacity, and/or quality of life in adults with HIV. Two independent reviewers screened the abstracts using the Cochrane Collaboration's protocol. The PEDro score was used to evaluate methodological quality. In total, 29 studies fulfilled the inclusion criteria. Individual studies suggested that exercise training contributed to improvement of physiologic and functional parameters, but that the gains were specific to the type of exercise performed. Resistance exercise training improved outcomes related to body composition and muscle strength, with little impact on quality of life. Aerobic exercise training improved body composition and aerobic capacity. Concurrent training produced significant gains in all outcomes evaluated, although moderate intensity and a long duration were necessary. We concluded that exercise training was shown to be a safe and beneficial intervention in the treatment of patients with HIV.

Abstract
BACKGROUND The extent to which patients follow treatments as prescribed is pivotal to treatment success. An exceptionally high level (> 95%) of HIV medication adherence is required to suppress viral replication and protect the immune system and a similarly high level (> 80%) of adherence has also been suggested in order to benefit from prescribed exercise programmes. However, in clinical practice, adherence to both often falls below the desirable level. This project aims to investigate a wide range of psychological and personality factors that may lead to adherence/non-adherence to medical treatment and exercise programmes. METHODS HIV positive patients who are referred to the physiotherapist-led 10-week exercise programme as part of the standard care are continuously recruited. Data on social cognitive variables (attitude, intention, subjective norms, self-efficacy, and outcome beliefs) about the goal and specific behaviours, selected personality factors, perceived quality of life, physical activity, self-reported adherence and physical assessment are collected at baseline, at the end of the exercise programme and again 3 months later. The project incorporates objective measures of both exercise (attendance log and improvement in physical measures such as improved fitness level, weight loss, improved circumferential anthropometric measures) and medication adherence (verified by non-invasive hair analysis). DISCUSSION The novelty of this project comes from two key aspects, complemented with objective information on exercise and medication adherence. The project assesses beliefs about both the underlying goal such as following prescribed treatment; and about the specific behaviours such as undertaking the exercise or taking the medication, using both implicit and explicit assessments of patients' beliefs and attitudes. We predict that i) the way people think about the underlying goal of their treatments explains medication and exercise behaviours over and above the effects of the behaviour-specific thinking and ii) the relationship between adherence to exercise and to medical treatment is stronger among those with more favourable views about the goal. Results from this study should identify the key contributing factors to inform subsequent adherence research and afford a more streamlined assessment matrix. The project also aims to inform patient care practices. UK CLINICAL RESEARCH NETWORK REGISTRATION NUMBER: UKCRN 7842.

Abstract
Physical activity has been recommended based on beneficial effects described in HIV-infected patients. However, such guidelines do not take into account actual sport behaviours and general attitudes towards physical activity. To evaluate actual sport activity and attitudes towards sport in HIV-infected versus non-infected individuals we conducted an anonymous questionnaire investigating the prevalence, as well as possible changes, in sports engagement and the overall attitude to physical activity. A total of 283 patients of a general care facility specialized in the treatment of HIV/AIDS in Berlin, Germany, participated; 124 were HIV infected and 159 were non-infected, mostly men who have sex with men (MSM) (88%), with a median age of 35 years. The HIV-infected participants had a median CD4+ count of 554 cells/µL and 48.8% of them were using antiretroviral therapy (ART) at the time of survey. The proportion of patients actually performing physical activity was significantly lower (P = 0.028) within the HIV-infected group (61.3%) than within the non-infected group (74.2%). This difference remained significant after accounting for possible confounders such as age, gender, injecting drug use and sexual preferences. Previously reported sport activity prevalence was similar in both groups on leaving school. From our data we could not identify an association between the time of HIV diagnosis and changes in sports activity. In conclusion, fewer HIV-infected individuals report physical activity than non-infected individuals. Sociodemographic studies to evaluate potential differences in sports behaviour are required in order to inform exercise guidelines for HIV-infected patients.

Abstract
BACKGROUND Persons living with the effects of chronic and disabling conditions are often at increased risk for the development of secondary conditions and disabilities that can lead to further decline in health status, independence, functional status, life satisfaction, and overall quality of life. OBJECTIVE The purpose of this study was to review the evidence for the benefits of wellness/health promotion interventions for persons with chronic and disabling conditions. METHODS The authors conducted a Medline search (1990-2007) using terms related to wellness and health promotion cross-referenced with general terms for chronic and disabling conditions, as well as 15 specific chronic and/or disabling conditions (e.g., multiple sclerosis, spinal cord injury). Selection of studies was limited to those published in English that reported randomized controlled trails or prospective studies that involved adult human subjects with a chronic and/or disabling condition. All selected studies focused on some aspect of a wellness or health promotion intervention and involved a comparison or control group. Of the 5,847 studies initially identified in the search using medical subject heading terms, 190 met the criteria for full review. Data were extracted from these publications and summarized using descriptive statistics. RESULTS Almost all studies (95%) explored the effects of wellness intervention in a sample diagnosed with a single condition (e.g., cancer, stroke, arthritis). Although the mean sample size was 100, the range in sample size varied widely (6-688); 25% of the studies had sample of 30 or fewer. Almost all studies (89.5%) reported positive effects of the wellness intervention, although the delivery and content of interventions as well as the measurement of outcomes, varied greatly. CONCLUSIONS Our findings support an immediate post-intervention positive impact of wellness interventions across persons with a wide variety of chronic and disabling conditions. Future research that clearly specifies primary study outcomes and follows the CONSORT guidelines will strengthen future reviews of the evidence and facilitate application of the evidence of practice.

Abstract
The purpose of this study was to determine what relationship exists among physical activity levels and viral load and CD4+ cell count in HIV-infected individuals. Increased viral load is associated with disease progression and symptom severity. A convenience sample of 66 male and female subjects between the ages of 18 and 64 years of age (mean 39 +/- 8) was recruited from a hospital-based HIV/AIDS clinic. Components of PA were assessed for three continuous days using a mini-motion logger wrist actigraph. These components included mean PA level, and PA index and acceleration index. Pearson's correlational analysis was used to test the strength of association between PA components and viral load or CD4+ cell count. A significant inverse relationship was found between mean PA level and viral load (p=0.047). An inverse relationship was also observed between PA index and viral load (p=0.0061). Neither mean PA nor PA index scores correlated with CD4+ cell counts. Acceleration index, a measure of PA intensity, showed no correlation to viral load or CD4+ cell counts. These findings suggest that increasing levels of physical activity might have beneficial effects on viral load in HIV-infected individuals.

Abstract
BACKGROUND Access to combination antiretroviral therapy has turned HIV into a chronic and manageable disease for many. This increased chronicity has been mirrored by increased prevalence of health-related challenges experienced by people living with HIV (Rusch 2004). Exercise is a key strategy for people living with HIV and by rehabilitation professionals to address these disablements; however, knowledge about the effects of exercise among adults living with HIV still is emerging. OBJECTIVES To examine the safety and effectiveness of aerobic exercise interventions on immunologic and virologic, cardiopulmonary, psychologic outcomes and strength, weight, and body composition in adults living with HIV. SEARCH STRATEGY Searches of MEDLINE, EMBASE, SCIENCE CITATION INDEX, CINAHL, HEALTHSTAR, PsycINFO, SPORTDISCUS and Cochrane Review Group Databases were conducted between 1980 and June 2009. Searches of published and unpublished abstracts and proceedings from major international and national HIV/AIDS conferences were conducted, as well as a handsearch of reference lists and tables of contents of relevant journals and books. SELECTION CRITERIA We included studies of randomised controlled trials (RCTs) comparing aerobic exercise interventions with no aerobic exercise interventions or another exercise or treatment modality, performed at least three times per week for at least four weeks among adults (18 years of age or older) living with HIV. DATA COLLECTION AND ANALYSIS Data on study design, participants, interventions, outcomes, and methodological quality were abstracted from included studies by two reviewers. Meta-analyses, using RevMan 5 computer software, were performed on outcomes when possible. MAIN RESULTS A total of 14 studies met inclusion criteria for this review and 30 meta-analyses over several updates were performed. Main results indicated that performing constant or interval aerobic exercise, or a combination of constant aerobic exercise and progressive resistive exercise for at least 20 minutes at least three times per week for at least five weeks appears to be safe and may lead to significant improvements in selected outcomes of cardiopulmonary fitness (maximum oxygen consumption), body composition (leg muscle area, percent body fat), and psychological status (depression-dejection symptoms). These findings are limited to participants who continued to exercise and for whom there were adequate follow-up data. AUTHORS' CONCLUSIONS Aerobic exercise appears to be safe and may be beneficial for adults living with HIV. These findings are limited by the small sample sizes and large withdrawal rates described in the studies. Future research would benefit from participant follow-up and intention-to-treat analysis. Further research is required to determine the optimal parameters in which aerobic exercise may be most beneficial for adults living with HIV.

Abstract
O uso da terapia anti-retroviral combinada (TARV) aumentou a expectativa de vida dos portadores do vírus da imunodeficiência humana (HIV) e, como conseqüência, torna-se constante o estudo do processo fisiopatológico da infecção e das estratégias de intervenção que possam melhorar a qualidade de vida destes indivíduos. O treinamento concorrente, definido como a associação dos componentes aeróbios e força na mesma sessão de exercícios pode ser inserido neste contexto. O objetivo deste artigo é revisar os aspectos centrais da infecção pelo HIV e as evidências existentes sobre o treinamento concorrente com séries múltiplas e simples nos parâmetros imunológico, virológico, cardiorrespiratório e neuromuscular de pessoas infectadas pelo HIV. O método utilizado foi uma revisão sistemática, com artigos publicados entre 2000-2007, nas bases de dados scielo e pubmed e também em dissertações e teses da biblioteca digital da educação física, esporte e saúde. As evidências científicas encontradas nos 8 estudos analisados indicam que o treinamento concorrente, tanto com séries múltiplas quanto séries simples, melhora os parâmetros cardiorrespiratório e neuromuscular; no entanto, os resultados dos parâmetros imunológico e virológico ainda não estão completamente esclarecidos, principalmente sobre os protocolos com séries simples. Considerando o número restrito de trabalhos apresentados, sugere-se o desenvolvimento de estudos com treinamento concorrente em vários desfechos clínicos para pessoas infectadas pelo HIV.

Abstract
BACKGROUND Home-based care (HBC), to promote quality-of-life and limit hospital care, is used in many countries, especially where public health services are overburdened. OBJECTIVES This review assessed the effects of HBC on morbidity and mortality in those with HIV/AIDS. SEARCH STRATEGY Randomised and controlled clinical trials of HBC including all forms of treatment, care and support offered in the home were included. A highly sensitive search strategy was used to search CENTRAL, MEDLINE, EMBASE, AIDSearch, CINAHL, PsycINFO/LIT. Risk of bias of all trials was assessed. SELECTION CRITERIA All randomised and controlled clinical trials were included of HIV/AIDS positive individuals, adults and children, of any gender, and from any setting. Home-based care, provided by family, lay and/or professional people, including all forms of treatment, care and support offered in the HIV/AIDS positive person's home as compared to hospital or institutional based care DATA COLLECTION AND ANALYSIS Titles, abstracts and descriptor terms of the electronic search results were screened independently by two authors for relevance based on the types of participants, interventions, and study design. Full text articles were obtained of all selected abstracts and an eligibility form was used to determine final study selection. Data extraction and assessment of risk of bias were done independently. Narrative synthesis of results were done. Relevant effect measures and the 95% confidence intervals were reported. MAIN RESULTS Ten studies randomised individuals and trial sizes varied from n=31 to n=549. One study randomised 392 households and enrolled a total of 509 persons with HIV and 1,521 HIV-negative household members. Two ongoing studies were identified. Intensive home-based nursing significantly improved self-reported knowledge of HIV and medications, self-reported adherence and difference in pharmacy drug refill (1 study). Another study, comparing proportion of participants with greater than 90% adherence, found statistically significant differences over time but no significant change in CD4 counts and viral loads. A third study found significant differences in HIV stigma, worry and physical functioning but no differences in depressive symptoms, mood, general health, and overall functioning. Comprehensive case management by trans-professional teams compared to usual care by primary care nurses had no significant difference in quality-of-life after 6-months of follow-up (n=57) and average length of time on service (n=549). Home total parenteral nutrition had no significant impact on overall survival and rate of re-hospitalisation. Two trials comparing computers with brochures/nothing/standard medical care found no significant effect on health status, and decision-making confidence and skill, but a reduction in social isolation after controlling for depression. Two trials evaluating home exercise programmes found opposing results. Home-based safe water systems reduced diarrhea frequency and severity among persons with HIV in Africa. AUTHORS' CONCLUSIONS Studies were generally small and very few studies were done in developing countries. There was a lack of studies truly looking at the effect of home based care itself or looking at significant end points (death and progression to AIDS). However, the range of interventions and HBC models evaluated can assist in making evidence-based decisions about HIV care and support.

Abstract
A aids é uma doença crônica, caracterizada pela depleção dos linfócitos T, sendo o vírus HIV o seu agente causador. A sua infecção e tratamento farmacológico estão ligados às alterações físicas e fisiológicas, que podem diminuir a qualidade de vida. Sendo assim, o objetivo do estudo foi elaborar uma revisão sistemática sobre os estudos publicados no PubMed e Capes entre 1998 e 2008, com humanos soropositivos e que investigaram os impactos do treinamento aeróbio e/ou resistido nos aspectos fisiológicos, metabólicos, psicológicos, imunológicos e físicos. Foram discutidos protocolos que utilizaram apenas treinamento de força ou aeróbio e os que utilizaram ambos e a grande maioria encontrou resultados favoráveis às variáveis pesquisadas. Quanto ao modelo de prescrição para essa população, este deve ser composto por exercícios de força, de oito a 15 repetições máximas (trabalho de hipertrofia) e por exercícios aeróbios (contínuo ou intervalado), com duração de 20 a 60 minutos e intensidade variando de 50 a 85% da frequência cardíaca máxima ou 45-85% do consumo máximo de oxigênio, ambos três a cinco vezes por semana. Dessa forma, ao elaborar um programa de atividade física, é importante conhecer a atual condição física e fisiológica do indivíduo HIV+, para que a sua condição de esforço não seja superestimada ou subestimada.

Abstract
HIV infection and HIV drug therapies result in physical and psychological challenges to those living with HIV. These conditions contribute to decreased functional aerobic capacity (FAC). The aim of this study was to determine the effects of a combined moderate-intensity aerobic and resistance exercise intervention on the FAC of HIV-infected individuals. Forty HIV-infected individuals were randomized to an exercise group (EX) who completed six weeks of moderate-intensity exercise training, or to a control group (CON) that did not receive the exercise intervention. Twice weekly, the EX group completed 30 minutes of moderate-intensity aerobic training followed by moderate-intensity resistance training. Prior to, and following, the intervention the FAC for each subject was determined by graded exercise treadmill stress test (GXT). At baseline testing, the mean FAC as determined by treadmill time-based estimation of maximal oxygen consumption was 25% below age-predicted values, a level of reduction indicating the presence of functional aerobic impairment (FAI). Following the intervention, the EX had a significant increase in time to fatigue and estimated VO(2) max (p<.001). Further, FAI was eliminated (1% above age predicted values) during the exercise training. The EX group also experienced decreased heart rates during Stages 1 (p=.02), 2 (p=.01), 4 (p=.05) and 6 (p=.02) of the GXT. The CON had no significant changes during the intervention period. These data indicate that six weeks of combined moderate-intensity aerobic and resistance training can improve FAC and eliminate FAI in those with HIV. Results suggest that the functional limitations common in HIV-infected individuals are due in part to detraining that is reversible through moderate exercise adherence.

Abstract
Stress among people living with HIV/AIDS (PLWHA) is associated with psychological morbidity. There are only a few stress scales specially developed for PLWHA and none of them is in Chinese. This study develops and validates a new Chinese Perceived Stress Scale among PLWHA (PSSHIV) in Shenzhen of Guangdong Province and Hengyang of Hunan Province in China during September 2006 through July 2007. In-depth interviews were administered to 58 PLWHA (33 males, mean age, 32) to generate the items, while 215 other PLWHA were interviewed in another survey to validate the instrument (136 males, mean age, 33). Exploratory factor analysis yielded 8 factors (percent variance explained, 71.47%), namely: social/psychological problems, sexual relationship, functional problems, social acceptance/rejection issues, work-related issues, family/offspring issues, accessibility to treatment, and treatment outcomes. The Cronbach alpha values ranged from 0.76 to 0.94 for the overall scale and the 8 subscales. The scores of the overall scale, the social/psychological problems, and functional problems subscales of the PSSHIV were significantly correlated with the Perceived Stress Scale (PSS), Depression, Anxiety and Stress Scale (DASS), and all domains of the Medical Outcomes Study HIV Health Survey (MOS-HIV) (correlation coefficient = 0.50 to 0.71 for positive correlations, and -0.73 to -0.21 for negative correlations, p < 0.05). The other 6 subscales of the PSSHIV were significantly correlated with the PSS, subscales of the DASS, and MOS-HIV (correlation coefficient = 0.16 to 0.39 for positive correlation, -0.58 to -0.15 for negative correlation, p < 0.05). This new instrument collected information from the PLWHA from qualitative interviews and the items are specific to the HIV/AIDS context. PSSHIV can be used for assessing the level of stress faced by PLWHA in China.
