Background: Safe landing in netball is fundamental. Research on the biomechanics of multidirectional landings is lacking, especially among netball players. Furthermore, few studies reporting the associations between ankle kinematics, isokinetic ankle muscle strength, muscle activities, and injury prevalence in South African netball have been undertaken.

Background: The Department of Health and Human Services HIV-1 Treatment Guidelines recommend drug resistance testing in HIV-1 RNA to guide the selection of antiretroviral therapy in patients with viremia. However, resistance-associated mutations (RAMs) in HIV-1 RNA may reflect only the patient's current regimen and can be lost during prolonged absence of therapy. We determined if HIV-1 DNA testing can provide drug resistance information beyond that identified in contemporaneous plasma virus.

Background: Habitual school backpack carriage causes neuro-musculoskeletal vertebral, shoulder and hand pain; deviated posture compromised cardiopulmonary function and proprioception.

Objective: Present a novel literature summary of the influence of backpack carriage associated with deviated cervical posture and compromised pulmonary function.

Method: An electronic literature appraisal adopting the Preferred Reporting Items for Systematic Reviews, using Google Scholar, Science Direct, EMBASE, AMED, OVID, PubMed and Sabinet search engines, was instituted during 2009-2019.

Background: Many patients with Down syndrome (PWDS) have poor cardiometabolic risk profiles, aerobic capacities and weak hypotonic muscles, primarily because of physical inactivity and poor diet.

Objectives: This study discusses the benefits of exercise therapy on body composition, aerobic capacity, muscle strength, proprioception and cardiometabolic profiles of PWDS.

Methods: A literature review using the Crossref metadatabase, following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), focusing on the period 2007-2018, was undertaken.
