The dramatic scale-up of HIV services in lower-income countries has led to the development of service delivery models reflecting the specific characteristics of HIV and its treatment as well as local contexts and cultures. Given the shared barriers and challenges faced by health programmes in lower-income countries, many of the implementation approaches developed for HIV programmes have the potential to contribute to the continuity care framework needed to address non-communicable diseases (NCDs) in resource-limited settings. HIV programmes are, in fact, the first large-scale chronic disease programmes in many countries, offering local and effective tools, models and approaches that can be replicated, adapted and expanded.

We sought to investigate the association between HBV or HCV infection and myocardial infarction in HIV-infected individuals.
Methods: The prospective observational database of the D:A:D collaboration of 11 cohorts of HIV-infected individuals, including 212 clinics in Europe, the United States and Australia was used.
The debate on the interaction between disease-specific programmes and health system strengthening in the last few years has intensified as experts seek to tease out common ground and find solutions and synergies to bridge the divide. Unfortunately, the debate continues to be largely academic and devoid of specificity, resulting in the issues being irrelevant to health care workers on the ground. Taking the theme 'What would entice HIV- and tuberculosis (TB)-programme managers to sit around the table on a Monday morning with health system experts', this viewpoint focuses on infection control and health facility safety as an important and highly relevant practical topic for both disease-specific programmes and health system strengthening.

However, there have been few investigations of the performance of ART eligibility criteria in pregnant and postpartum women in resource-limited settings.
Methods: Pregnant and recently postpartum HIV+ women received CD4+ cell count and World Health Organization (WHO) clinical staging at enrollment into the mother-to-child transmission Plus Initiative.
Aims: HIV-infected patients receiving combination antiretroviral therapy may experience metabolic complications, potentially increasing their risk of cardiovascular diseases (CVDs). Furthermore, exposures to some antiretroviral drugs seem to be independently associated with increased CVD risk. We aimed to develop cardiovascular risk-assessment models tailored to HIV-infected patients.

After the introduction of standard control practices in 1995, 36 million people were cured and about 6 million deaths were averted. However, substantial scientific advances and innovative solutions are urgently needed together with creative new strategies.

Design: An observational multicentre cohort study.
Methods: All HIV-positive individuals included in one of the cohorts in the Data Collection on Adverse Events of Anti-HIV drugs (D:A:D) Study were included.
Promoting linkages between tuberculosis (TB) and human immunodeficiency virus (HIV) treatment and prevention programs in resource-constrained environments where both diseases are prevalent is essential to improve the diagnosis, treatment, and outcomes for patients affected by both diseases. In this article, we share insights based on our experiences supporting integrated TB and HIV service delivery programs, including intensified TB case finding, isoniazid preventive therapy, infection control, and initiation of antiretroviral therapy. Our experience indicates that successful integration of TB and HIV services in resource-constrained environments is feasible, although programmatic, infrastructural, and staffing challenges remain.

The domestic epidemic has had the heaviest impact on men who have sex with men and persons from racial and ethnic minority populations, particularly black persons. For example, black men who have sex with men represent <1% of the US population but 25% of new HIV infections, according to Centers for Disease Control and Prevention estimates published in 2008.

It is important to understand this population's tuberculosis-related knowledge, attitudes, and beliefs (KAB) as they may affect treatment acceptance and completion. KAB in 84 US-born and 167 foreign-born LTBI patients enrolled in a clinical trial assessing treatment completion at an urban public hospital were assessed at baseline.

Methods: In an open-label, randomized, controlled trial in Durban, South Africa, we assigned 642 patients with both tuberculosis and HIV infection to start antiretroviral therapy either during tuberculosis therapy (in two integrated-therapy groups) or after the completion of such treatment (in one sequential-therapy group).
Background: With the rapid expansion of antiretroviral therapy (ART) services in sub-Saharan Africa there is growing recognition of the importance of fertility and childbearing among HIV-infected women. However there are few data on whether ART initiation influences pregnancy rates.
Methods And Findings: We analyzed data from the Mother-to-Child Transmission-Plus (MTCT-Plus) Initiative, a multicountry HIV care and treatment program for women, children, and families.
Objective: HIV-infected women need access to safe and effective contraception. Recent animal and human data suggest that hormonal contraception may accelerate HIV disease progression.
Methods: We compared the incidence of HIV disease progression among antiretroviral therapy-naive women with and without exposure to hormonal contraception at 13 sites in Africa and Asia.
Objective: To assess the effects of decreased antiretroviral therapy exposure on body fat and metabolic parameters.
Design: Substudy of the Strategies for Management of Anti-Retroviral Therapy study, in which participants were randomized to intermittent CD4-guided [Drug Conservation (DC) group] or to continuous [Viral Suppression (VS) group] antiretroviral therapy.
Methods: Participants at 33 sites were coenrolled in the Strategies for Management of Anti-Retroviral Therapy Body Composition substudy.

Design: Analysis of data from adult patients enrolled in the MTCT-Plus Initiative who initiated ART between 2003 and 2006 in seven countries in Sub-Saharan Africa and Thailand.
Methods: Mean population changes were assessed and multivariable mixed linear regression modeling was used to examine covariate effects on differences in absolute CD4 cell count responses.

Urban malaria is a growing problem in Africa. Small-scale spatial studies are useful in identifying foci of malaria transmission in urban communities. A population-based cohort study comprising 8,088 individuals was conducted in Adama, Ethiopia.

Methods: We described the prevalence of the metabolic syndrome in patients under follow-up at the end of six calendar periods from 2000 to 2007. The definition that was used for the metabolic syndrome was modified to take account of the use of lipid-lowering and antihypertensive medication, measurement variability and missing values, and assessed the impact of these modifications on the estimated prevalence.

Although much has been learned about the implementation of HIV prevention, care, and treatment services in resource-limited settings, the broader impact of the rapid scale-up of HIV programs on fragile health systems has only recently been explored. A high-level working group identified priority research questions regarding the impact of HIV scale-up on key elements of health systems: service delivery; management; information, evidence, and strategic planning; medical products, vaccines, and technologies; health financing and payments; leadership and governance; and the behaviors of providers, consumers, and communities. Rigorous multisectoral studies are needed if HIV program expansion to the millions still needing care and treatment is to continue, and if the synergies between vertically funded HIV programs and the health systems of which they are a part are to be maximized to strengthen nations' ability to meet all their health challenges.
