This paper describes the development, content, and capabilities of the online Global HIV Archive (GHA). With the goal of facilitating widespread adaptation and appropriate use of efficacious HIV prevention programs throughout the globe, GHA has: first, expanded and updated the search for HIV prevention programs originating in low-resource countries; second, identified those meritorious HIV prevention programs meeting established efficacy criteria of technical merit, replicability, and positive outcomes; third, prepared both implementation and evaluation materials from the efficacious programs for public use; fourth, developed interactive wizards or capacity-building tools to facilitate appropriate program selection, implementation, and adaptation; and, fifth, made the efficacious programs and accompanying wizards available to health practitioners throughout the globe in both printed and online formats.

Recent interest by physicists in social networks and disease transmission factors has prompted debate over the topology of degree distributions in sexual networks. Social network researchers have been critical of "scale-free" Barabasi-Albert approaches, and largely rejected the preferential attachment, "rich-get-richer" assumptions that underlie that model. Instead, research on sexual networks has pointed to the importance of homophily and local sexual norms in dictating degree distributions, and thus disease transmission thresholds. Injecting Drug User (IDU) network topologies may differ from the emerging models of sexual networks, however. Degree distribution analysis of a Brooklyn, NY, IDU network indicates a different topology than the spanning tree configurations discussed for sexual networks, instead featuring comparatively short cycles and high concurrency. Our findings suggest that IDU networks do in some ways conform to a "scale-free" topology, and thus may represent "reservoirs" of potential infection despite seemingly low transmission thresholds.

Purpose: Despite high levels of depression among persons living with HIV (PLWHIV), little research has investigated the relationship of depression to work status and income in PLWHIV in sub-Saharan Africa, which was the focus of this analysis.

Methods: Baseline data from a prospective longitudinal cohort of 798 HIV patients starting antiretroviral therapy in Kampala, Uganda were examined. In separate multivariate analyses, we examined whether depressive severity and symptom type [as measured by the Patient Health Questionnaire (PHQ-9)] and major depression [diagnosed with the Mini International Neuropsychiatric Interview (MINI)] were associated with work status and income, controlling for demographics, physical health functioning, work self-efficacy, social support and internalized HIV stigma.

Results: 14% of the sample had Major Depression and 66% were currently working. Each measure of depression (PHQ-9 total score, somatic and cognitive subscales; Major Depression diagnosis) was associated with not working and lower average weekly income in bivariate analysis. However, none of the depression measures remained associated with work and income in multivariate analyses that controlled for other variables associated with these economic outcomes.

Conclusions: These findings suggest that while depression is related to work and income, its influence may only be indirect through its relationship to other factors such as work self-efficacy and physical health functioning.

BACKGROUND: The frequency of neurocognitive impairment (NCI) in human immunodeficiency virus (HIV)-infected individuals remains high despite the availability of potent antiretroviral therapy (ART). The concurrence of depression among HIV-infected patients with NCI is common, especially among older individuals. Depression has been implicated as a risk factor for impaired neuropsychological performance (NP). This study explored the relationship between depressive symptoms and NP testing in HIV-infected individuals. METHODS: A cross-sectional analysis was performed within the Hawaii Aging with HIV Cohort, a large prospective study of cognition of older (50 or more years old) compared to younger (20 to 39 years old) HIV-infected individuals. RESULTS: Two hundred and eighty-five HIV infected participants (157 older and 128 younger) were administered a battery of NP tests to measure performance in major cognitive domains. Depressive symptoms were measured using the Beck Depression Inventory (BDI). The rates of depressive symptoms and neuropsychological impairment were similar in older and younger groups. Multivariate analyses revealed depressive symptoms were associated with NP test impairment in the younger group. In the older group, depressive symptoms were not associated with NP. CONCLUSION: This study suggests that depressive symptoms are associated with NP test impairment in younger HIV-infected individuals, but not in older individuals.
