Effectiveness of aerobic exercise for adults living with HIV: systematic review and meta-analysis using the Cochrane Collaboration protocol

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

Finishing the euchromatic sequence of the human genome

The sequence of the human genome encodes the genetic instructions for human physiology, as well as rich information about human evolution. In 2001, the International Human Genome Sequencing Consortium reported a draft sequence of the euchromatic portion of the human genome. Since then, the international collaboration has worked to convert this draft into a genome sequence with high accuracy and nearly complete coverage. Here, we report the result of this finishing process. The current genome sequence (Build 35) contains 2.85 billion nucleotides interrupted by only 341 gaps. It covers ∼99% of the euchromatic genome and is accurate to an error rate of ∼1 event per 100,000 bases. Many of the remaining euchromatic gaps are associated with segmental duplications and will require focused work with new methods. The near-complete sequence, the first for a vertebrate, greatly improves the precision of biological analyses of the human genome including studies of gene number, birth and death. Notably, the human enome seems to encode only 20,000-25,000 protein-coding genes. The genome sequence reported here should serve as a firm foundation for biomedical research in the decades ahead

Effectiveness of Progressive Resistive Exercise (PRE) in the context of HIV: systematic review and meta-analysis using the Cochrane Collaboration protocol

Abstract Background HIV is increasingly considered a chronic illness. More individuals are living longer and aging with the health-related consequences associated with HIV and multi-morbidity. Exercise is a self-management approach that can promote health for people aging with HIV. We examined the safety and effectiveness of progressive resistive exercise (PRE) 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. Searching databases up to April 2013, we included randomized controlled trials that compared PRE with no exercise or another intervention performed at least three times per week for at least four weeks with adults living with HIV. Two reviewers independently determined study eligibility. We extracted data from included studies and assessed risk of bias using the Cochrane Collaboration risk of bias tool. Meta-analyses were conducted using random effects models with Review Manager (RevMan) computer software. Results Twenty studies met inclusion criteria (n = 764 participants at study completion); the majority of participants were men (77%) taking antiretroviral therapy (14/20 included studies). Exercise interventions included PRE alone (8 studies) or a combination of resistive and aerobic exercise (12 studies) ranging from 6 to 52 weeks in duration. Thirty-four meta-analyses were performed. Results demonstrated statistically significant improvements in cardiorespiratory status (maximum oxygen consumption, exercise time), strength (chest press, knee flexion), weight, and body composition (arm and thigh girth, leg muscle area) among exercisers versus non-exercisers. We found no significant differences in change in CD4 count and viral load. We were unable to perform meta-analyses for psychological outcomes however results from individual studies demonstrated improvements in health-related quality of life with exercisers compared with non-exercisers. Conclusions Performing progressive resistive exercise (PRE) or a combination of resistive and aerobic exercise at least three times per week for at least six weeks is safe and can lead to improvements in cardiorespiratory fitness, strength, weight, and body composition for adults with HIV. Exercise may be considered a safe and beneficial for enhancing the health of medically stable adults aging with HIV

Provider training and experience for people living with HIV/AIDS

BACKGROUND: The complexity of HIV/AIDS raises challenges for the effective delivery of care. It is important to ensure that the expertise and experience of care providers is of high quality. Training and experience of HIV/AIDS providers may impact not only individual patient outcomes but increasingly on health care costs as well. OBJECTIVE: The objective of this review is to assess the effects of provider training and experience on people living with HIV/AIDS on the following outcomes: immunological (ie. viral load, CD4 count), medical (ie. mortality, proportion on antiretrovirals), psychosocial (ie. quality of life measures) and economic outcomes (ie health care costs). CRITERIA FOR CONSIDERING STUDIES FOR THIS REVIEW: We searched MEDLINE, EMBASE, Dissertation Abstracts International (DAI), CINAHL, HealthStar, PsycInfo, PsycLit, Social Sciences Abstracts, and Sociological Abstracts from January 1, 1980 through May 29, 2009. Electronic searches were performed for abstracts from major international AIDS conferences. Reference lists from pertinent articles, books and review articles were retrieved and reviewed. SELECTION CRITERIA: Randomized controlled trials (RCTs), controlled clinical trials, cohort, case control, cross-sectional studies and controlled before and after designs that examined the qualifications/training and patient volume of HIV/AIDS care of providers caring for persons known to be infected with HIV/AIDS were included. DATA COLLECTION AND ANALYSIS: At least two authors independently assessed trial quality and extracted data. Study authors were contacted for further information as required. Assessment of confounding factors was undertaken independently by two reviewers. MAIN RESULTS: A total of four studies (one randomized controlled trial, three non- randomized studies) involving 8488 people living with HIV/AIDS were included. The main findings of this review demonstrated a trend to improved outcomes when treated by a provider with more training/expertise in HIV/AIDS care in the outpatient (clinic) setting. Due to the heterogeneity of the included studies, we could not perform a meta-analysis. We present a descriptive review of the results. AUTHORS' CONCLUSIONS: The results demonstrate improved medical outcomes when treated by a provider with more training/expertise in HIV/AIDS care in the outpatient (clinic) setting. Since all of these studies were conducted in North America, this does not address any issues regarding the level of training/expertise required by providers working in countries with more limited resources. Practitioners who do not consider themselves "experts" in HIV/AIDS care and care for few of these patients need to seriously consider this review which demonstrates a trend towards worse patient outcomes when receiving care by those with low caseloads/training in HIV/AIDS care

Colorectal cancer among persons with HIV: protocol for a systematic review and meta-analysis

Abstract Background As persons with HIV live longer, data regarding the epidemiology of colorectal cancer are required to optimize the long-term management of these patients. The purpose of this systematic review and meta-analysis is to synthesize evidence regarding the incidence of colorectal cancer in persons with HIV. Methods/design Our primary outcome is the standardized incidence ratio of colorectal cancer among persons with HIV relative to rates in persons not living with HIV. Our secondary objectives are to summarize the evidence for differences with respect to stage at diagnosis, site of disease, and mortality due to colorectal cancer. We will search electronic bibliographic databases from their inception date, as well as conference proceedings and reference lists of included articles. Two investigators will independently screen citations and full-text articles, conduct data abstraction, and appraise study quality. We will examine clinical, methodological, and statistical heterogeneity among studies prior to conducting meta-analysis. Random effects meta-analysis methods will be employed to estimate standardized incidence ratios. These data will inform the development of guidelines for colorectal cancer screening in persons with HIV. Systematic review registration PROSPERO CRD4201401344
