Optimizing HIV Services for Key Populations in Public-Sector Clinics in Myanmar.

Key populations, ie, female sex workers, men who have sex with men, transgender people, people who inject drugs, and people in prisons and other closed settings, experience stigma, discrimination, and structural barriers when accessing HIV prevention and care. Public health facilities in Myanmar became increasingly involved in HIV service delivery, leading to an urgent need for healthcare workers to provide client-centred, key population-friendly services. Between July 2017-June 2018, the Myanmar Ministry of Health and Sports and National AIDS Programme collaborated with ICAP at Columbia University and the US Centers for Disease Control and Prevention to implement a quasi-experimental, multicomponent intervention including healthcare worker sensitization training with pre- and post- knowledge assessments, healthcare worker and client satisfaction surveys, and structural changes. We observed modest improvements among healthcare workers (n = 50) in knowledge assessments. Classification of clients into key population groups increased and fewer clients were classified as low risk. Key population clients reported favourable perceptions of the quality and confidentiality of care through self-administered surveys. Our findings suggest public health facilities can deliver HIV services that are valued by key population clients.

Association of physical function and performance with peak VO2 in elderly patients with end stage kidney disease.

BACKGROUND: Physical function is impaired in end stage renal disease (ESRD). Various instruments have been used to assess the functional capabilities and health status of patients with ESRD, but it is not known which has the best association with peak VO2. AIMS: To assess the association between functional measures in ESRD. METHODS: Thirty nine elderly ESRD patients were evaluated with commonly used functional, health status, and quality of life measures, including maximal cardiopulmonary exercise testing (CPET), 6-min walk (6MWT), sit-to-stand test (STS), Veterans Specific Activity Questionnaire (VSAQ), upper and lower body strength, pulmonary function tests, and body composition determined by dual X-ray absorptiometry. The association between performance on these functional tools, clinical variables, and exercise test responses was assessed, and a non-exercise test multivariate model was developed to predict peak VO2. RESULTS: Peak VO2 was modestly related to VSAQ score (r = 0.59, p < 0.01), indices of upper and lower body strength (r = 0.45, p < 0.01 for both), and FEV1 (r = 0.51, p < 0.01). Functional and quality of life questionnaires were generally poorly related to one another and to peak VO2. In a multivariate model, 6MWT performance, forced expiratory volume in 1 s (FEV1), and VSAQ score were the best predictors of peak VO2, yielding a multiple R = 0.82, accounting for 67% of the variance in peak VO2. CONCLUSION: Exercise capacity can be reasonably estimated using non-exercise test variables in patients with ESRD, including a symptom questionnaire (VSAQ), 6MWT and FEV1.

Physical Performance Testing in Kidney Transplant Candidates at the Top of the Waitlist.

RATIONALE & OBJECTIVE: Frailty and poor physical function are associated with adverse kidney transplant outcomes, but how to incorporate this knowledge into clinical practice is uncertain. We studied the association between measured physical performance and clinical outcomes among patients on kidney transplant waitlists. STUDY DESIGN: Prospective observational cohort study. SETTING & PARTICIPANTS: We studied consecutive patients evaluated in our Transplant Readiness Assessment Clinic, a top-of-the-waitlist management program, from May 2017 through December 2018 (N=305). We incorporated physical performance testing, including the 6-minute walk test (6MWT) and the sit-to-stand (STS) test, into routine clinical assessments. EXPOSURES: 6MWT and STS test results. OUTCOMES: The primary outcome was time to adverse waitlist outcomes (removal from waitlist or death); secondary outcomes were time to transplantation and time to death. ANALYTICAL APPROACH: We used linear regression to examine the relationship between clinical characteristics and physical performance test results. We used subdistribution hazards models to examine the association between physical performance test results and outcomes. RESULTS: Median 6MWT and STS results were 393 (IQR, 305-455) m and 17 (IQR, 12-21) repetitions, respectively. Clinical characteristics and Estimated Post-Transplant Survival scores accounted for only 14% to 21% of the variance in 6MWT/STS results. Physical performance test results were associated with adverse waitlist outcomes (adjusted subdistribution hazard ratio [sHR] of 1.42 [95% CI, 1.30-1.56] per 50-m lower 6MWT test result and 1.53 [95% CI, 1.33-1.75] per 5-repetition lower STS test result) and with transplantation (adjusted sHR of 0.80 [95% CI, 0.72-0.88] per 50-m lower 6MWT test result and 0.80 [95% CI, 0.71-0.89] per 5-repetition lower STS test result). Addition of either STS or 6MWT to survival models containing clinical characteristics enhanced fit (likelihood ratio test P<0.001). LIMITATIONS: Single-center observational study. Other measures of global health status (eg, Fried Frailty Index or Short Physical Performance Battery) were not examined. CONCLUSIONS: Among waitlisted kidney transplant candidates with high kidney allocation scores, standardized and easily performed physical performance test results are associated with waitlist outcomes and contain information beyond what is currently routinely collected in clinical practice.

A randomized controlled trial of exercise to prevent muscle mass and functional loss in elderly hemodialysis patients: Rationale, study design, and baseline sample.

BACKGROUND: Elderly maintenance hemodialysis (MHD) patients exhibit muscle wasting and impaired physical function. This trial determines whether MHD patients benefit from a 12-week home-based exercise program, protein supplementation, or both. DESIGN: and Methods: This is a randomized, blinded controlled trial involving 60 elderly MHD patients with impaired exercise capacity and function. Patients are randomized into either a homebased exercise program or normal care over a 12-week period. Measures at baseline include peak VO2, strength and body composition as well as cognitive and disease-specific questionnaires. Muscle biopsies are obtained and analyzed for protein signaling, expression of IGF-1, androgen receptors, and myostatin. RESULTS: At baseline, patient characteristics in the exercise and normal care groups were similar by age, gender and anthropomorphic measures. Peak VO2 was impaired (14.7 ±â€¯3.3 ml/kg/min), representing 55 ±â€¯14% of the age-predicted value. Six-minute walk distance was 322 ±â€¯71 m, and the mean 1-min sit to stand test was 18 ±â€¯8 repetitions, representing 69 ±â€¯16% and 55 ±â€¯22% of the age-predicted values, respectively. Indices of muscle function, including upper and lower body and hand grip strength all indicate marked impairment. Quality of life (QoL) using the SF36, the Beeson cognitive test, and KDQOL all suggest marked impairments compared to age-expected reference values for non-MHD patients. CONCLUSIONS: Patients undergoing MHD exhibit markedly reduced physical function and QoL. Thus, there are potentially significant gains to be made through a program of aerobic and resistance exercise. We anticipate this trial will demonstrate that home-based exercise improves cardiopulmonary function, protein signaling and QoL, and increases muscle mass, strength, and body composition.

Prehabilitation for kidney transplant candidates: Is it time?

Many patients become frail with diminished cardiorespiratory fitness while awaiting kidney transplantation. Frailty and poor fitness powerfully predict mortality, transplant graft survival, and healthcare utilization after kidney transplantation. Efforts to intervene with post-transplant physical therapy have been met with limited success, in large part due to high study dropout. We reviewed the literature on chronic kidney disease and exercise to propose a clinical framework for physical therapy interventions to improve fitness, scheduled for before the transplant. This framework may lead to better patient retention and compliance, and thus demonstrate better efficacy in mitigating the effects of frailty and poor fitness after kidney transplantation.
