The effects of aerobic exercises on high sensitivity C-reactive protein and depression in patients living with HIV infection; a systematic review with meta-analysis
Bibliographic record
Abstract
Abstract Background HIV infection and chronic use of highly active antiretroviral therapy have been associated with increased expression of pro-inflammatory biomarkers (e.g. high-sensitivity C-reactive protein) and major affective disorders (e.g. depression). There is a growing research interest in aerobic exercise as an adjunct therapy on inflammatory outcomes and depression in people living with HIV (PLHIV) who are undergoing antiretroviral therapy. Synthesizing and appraising available evidence may be essential to guide practice and future research on exercise intervention to this population. This review evaluated the effects of aerobic exercises on serum levels of high-sensitivity C-reactive protein (hs-CRP) and depressive symptoms in PLHIV. Methods Cochrane Central Register of Controlled Trials, MEDLINE, PEDRO, EMBASE, AMED, CINAHL, and Web of Science were systematically searched to include clinical trials that investigated the effects of aerobic exercises on hs-CRP and/or depression in PLWH. Two reviewers independently screened all the articles for eligibility and also evaluated the risk of bias using the Cochrane Collaboration risk of bias assessment tool. Data were extracted and meta-analyses conducted using Review Manager Software. Results Six studies (261 participants) met the inclusion criteria and were included in the review. Four of the studies reported on depressive symptoms and two on hs-CRP outcome The meta-analysis result showed a significant (Z=3.78, p<0.0002) decrease in depression scores in PLWH; implying that aerobic exercise interventions reduce depressive symptoms among PLWH. The two studies that reported on hs-CRP outcome, found no significant effect of aerobic exercise on hs-CRP. Overall, the GRADE evidence for this review was of moderate quality. Conclusion There was evidence that aerobic exercises of about 24-60 minutes duration, two to five times per week can lead to a significant improvement in depression level but not hs-CRP in PLWH. However, it should not be concluded as ‘no evidence of effect’ because the included trials do not have sufficient power to detect treatment effects. Thus, further homogenous research with enough “power” is necessary for a conclusive estimate of effects.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
