Background:
Physical impairment is highly prevalent in HIV-infected patients. We conducted a systematic review of published studies that included studies comparing muscle function in HIV-infected patients to matched healthy controls, and studies comparing aerobic capacity in HIV-infected patients with that observed in matched healthy controls.
Design:
Systematic review and meta-analysis.
Methods:
We searched for references on MEDLINE, SciELO, Cumulative Index to Nursing and Allied Health (CINAHL), and Scopus up to December 2017. Weighted mean differences and 95% confidence intervals (CIs) were calculated, and heterogeneity was assessed using the I test.
Results:
A total of 30 studies, covering 2148 healthy controls and 2161 HIV-infected patients, fulfilled the inclusion criteria. The average muscle strength and aerobic capacity were significantly lower in HIV-infected patients. Meta-analysis revealed moderate-quality evidence of weaker muscle strength and aerobic capacity in HIV-infected patients. A significant difference in lower-body strength of 1.07 (95% CI: 0.29 to 1.84) was found for participants in the healthy control group compared with HIV group. A significant difference in aerobic capacity (peak VO2) of 8.4 (95% CI: 4.8 to 12.0) was found for participants in the healthy control group compared with HIV group.
Conclusions:
Muscle strength and aerobic capacity of HIV-infected patients are reduced in comparison with healthy controls. Additional studies are needed to define the best interventions to improve the physical function in HIV-infected patients.

Acid Strength and Molecular Structure
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...
