Interventions linking family planning and HIV services were generally considered feasible and effective, though overall evaluation rigor was low.

BackgroundThe international community agrees that the Millennium Development Goals will not be achieved without ensuring universal access to both sexual and reproductive health (SRH) services and HIV/AIDS prevention, treatment, care and support. Recently, there has been increasing awareness and discussion of the possible benefits of linkages between SRH and HIV programmes at the policy, systems and service delivery levels. However, the evidence for the efficacy of these linkages has not been systematically assessed.MethodsWe conducted a systematic review of the evidence for interventions linking SRH and HIV. Structured methods were employed for searching, screening and data extraction. Studies from 1990 to 2007 reporting pre-post or multi-arm evaluation data from SRH-HIV linkage interventions were included. Study design rigour was scored on a nine-point scale. Unpublished programme reports were gathered as "promising practices".ResultsOf more than 50,000 citations identified, 185 studies were included in the review and 35 were analyzed. These studies had heterogeneous interventions, populations, objectives, study designs, rigour and measured outcomes. SRH-HIV linkage interventions were generally considered beneficial and feasible. The majority of studies showed improvements in all outcomes measured. While there were some mixed results, there were very few negative findings. Generally, positive effects were shown for key outcomes, including HIV incidence, sexually transmitted infection incidence, condom use, contraceptive use, uptake of HIV testing and quality of services. Promising practices (n = 23) tended to evaluate more recent and more comprehensive programmes. Factors promoting effective linkages included stakeholder involvement, capacity building, positive staff attitudes, non-stigmatizing services, and engagement of key populations.ConclusionsExisting evidence provides support for linkages, although significant gaps in the literature remain. Policy makers, programme managers and researchers should continue to advocate for, support, implement and rigorously evaluate SRH and HIV linkages at the policy, systems and service levels.

Our findings should be interpreted in the context of other limitations. The observed decline occurred in the context of a health care delivery system without direct financial incentives to perform tests. Nevertheless, the substantial reduction in MPI use demonstrates the ability to reduce testing on a large scale with anticipated reductions in health care costs. Cardiol. 2005;46 (8):1587-1605. 4.

IMPORTANCE Azithromycin is one of the most commonly prescribed antibiotics in the US. It has been associated with an increased risk of cardiovascular death in some observational studies. OBJECTIVE To estimate the relative and absolute risks of cardiovascular and sudden cardiac death after an outpatient azithromycin prescription compared with amoxicillin, an antibiotic not known to increase cardiovascular events. DESIGN, SETTING, AND PARTICIPANTSThis retrospective cohort study included 2 large, diverse, community-based integrated care delivery systems with comprehensive capture of encounters and prescriptions from January 1, 1998, to December 31, 2014. The cohort included patients aged 30 to 74 years who had at least 12 months of health-plan enrollment prior to antibiotic exposure. The exclusion criteria were absence of prescription benefits, prescription for more than 1 type of study antibiotic within 10 days, hospitalization or nursing home residence, and serious medical conditions.Risk of cardiovascular death associated with azithromycin vs amoxicillin exposure was calculated after controlling for confounding factors using a propensity score. Data were analyzed from December 1, 2016, to March 30, 2020. EXPOSURES Outpatient prescription of azithromycin or amoxicillin. MAIN OUTCOMES AND MEASURESThe primary outcomes were cardiovascular death and sudden cardiac death. An a priori subgroup analysis quantified the effects of azithromycin exposure among patients with increased baseline cardiovascular risk. The secondary outcomes were noncardiovascular death and all-cause mortality. RESULTSThe study included 7 824 681 antibiotic exposures, including 1 736 976 azithromycin exposures (22.2%) and 6 087 705 amoxicillin exposures (77.8%), among 2 929 008 unique individuals (mean [SD] age, 50.7 [12.3] years; 1 810 127 [61.8%] women). Azithromycin was associated with a significantly increased hazard of cardiovascular death (hazard ratio [HR], 1.82; 95% CI, 1.23-2.67) but not sudden cardiac death (HR, 1.59; 95% CI, 0.90-2.81) within 5 days of exposure.No increases in risk were found 6 to 10 days after exposure. Similar results were observed in patients within the top decile of cardiovascular risk (HR, 1.71; 95% CI, 1.06-2.76). Azithromycin was also associated with an increased risk of noncardiovascular death (HR, 2.17; 95% CI, 1.44-3.26) and all-cause mortality (HR, 2.00; 95% CI, 1.51-2.63) within 5 days of exposure. CONCLUSIONS AND RELEVANCEThese findings suggest that outpatient azithromycin use was associated with an increased risk of cardiovascular death and noncardiovascular death. Causality cannot be established, particularly for noncardiovascular death, owing to the likelihood of residual confounding.

People living with HIV often have unmet needs for sexual and reproductive health (SRH) services. We present results of a systematic review of studies offering SRH services targeted to people living with HIV. Studies were selected from a broader SRH and HIV linkages review. Inclusion criteria included: (1) peer-reviewed journal articles with a pre-post or multiple-arm study design; (2) reported post-intervention evaluation data; and (3) published 1 January 1990 through 31 December 2007. Nine studies were identified with an average rigour score of 5.1 out of 9. Services included family planning (one study), sexually transmitted infection (STI) services (two studies), combined family planning and STI services (three studies) and multiple services (three studies). The review identified mostly positive effects on the outcomes measured, including condom and contraceptive use and quality of services. Yet gaps remain in the research to establish the best approaches for addressing needs and choices of people living with HIV. There is a need for high-quality intervention studies to determine the most successful and cost-effective strategies for providing SRH services to people living with HIV.

Background & Aims Abdominal obesity and increasing body mass index are risk factors for esophageal adenocarcinoma and its main precursor, Barrett’s esophagus; however, there are no known biological mechanisms for these associations or regarding why only some patients with gastroesophageal reflux disease develop Barrett’s esophagus. We evaluated the association between Barrett’s esophagus and multimers of an adipose-associated hormone, adiponectin. Methods We conducted a case-control study evaluating the associations between adiponectin (total, high molecular weight, and low/medium molecular weight) and Barrett’s esophagus within the Kaiser Permanente Northern California population. Patients with a new diagnosis of Barrett’s esophagus (cases) were matched to patients with gastroesophageal reflux disease (GERD) without Barrett’s esophagus and to population controls. Results Complete serologic and epidemiologic data were available for 284 cases, 294 GERD controls, and 285 population controls. Increasing adiponectin levels were a risk factor for Barrett’s esophagus among patients with gastroesophageal reflux disease (total adiponectin fourth vs. first quartile odds ratio [OR]=1.96; 95% confidence interval (CI) 1.17–3.27; high molecular weight adiponectin OR=1.65; 95% CI 1.00–2.73; low/medium molecular weight adiponectin OR=2.18; 95% CI 1.33–3.56, but not compared with population controls. The associations were significantly stronger among patients reporting frequent GERD symptoms and among smokers (p-values interaction <0.01). Conclusion Adiponectin levels are positively associated with the risk of Barrett’s esophagus among patients with GERD and among smokers, but not among population controls without GERD symptoms. Higher adiponectin concentrations may either independently contribute to the aberrant healing of esophageal injury into Barrett’s esophagus or be a marker for other factors.

Background Abdominal obesity is a risk factor for Barrett’s esophagus independent of GERD symptoms, but little is understood about the biological mechanisms between obesity and the carcinogenic pathway of esophageal adenocarcinoma. Aims To evaluate whether ghrelin and leptin may partially explain the association between obesity and Barrett’s esophagus. Methods We conducted a case–control study using patients with a new diagnosis of Barrett’s esophagus (cases) and two control groups frequency matched to cases for age, gender, and geographic region: (1) patients with gastroesophageal reflux disease (GERD) and (2) a sample of the general population. We generated odds ratios using logistic regressions to evaluate quartiles of serum ghrelin or serum leptin, adjusting for known risk factors for Barrett’s esophagus. We evaluated potential interaction variables using cross products and ran stratified analyses to generate stratum-specific odds ratios. Results A total of 886 participants were included in the analysis. Higher ghrelin concentrations were associated with an increased risk of Barrett’s esophagus, when compared to the population controls, but not the GERD controls. Ghrelin concentrations were not associated with the frequency of GERD symptoms, but ghrelin’s relationship with Barrett’s esophagus varied significantly with the frequency of GERD symptoms. Leptin concentrations were positively associated with at least weekly GERD symptoms among the population controls and were inversely associated with Barrett’s esophagus only among the GERD controls. Adjusting for waist circumference did not change the main associations. Conclusion Higher levels of ghrelin were associated with an increased risk of Barrett’s esophagus among the general population. In contrast, leptin was positively associated with frequent GERD symptoms, but inversely associated with the risk of Barrett’s esophagus among the GERD controls.
