BACKGROUND: In China, western blot (WB) is the recommended procedure for the diagnosis of HIV infection. However, this technique is time consuming and labor intensive, and its complexity restricts wide application in resource-limited regions. OBJECTIVE: The aim of this study was to evaluate the efficacy of a dry blood spots (DBS)-urine paired enzyme-linked immunosorbent assay (ELISA) test, instead of WB, for HIV antibody detection. STUDY DESIGN: Plasma, DBS, and urine samples were collected from 1213 subjects from different populations...

Routine opt-out HIV screening is recommended for everyone between 13 and 64 years of age. An urban, academic emergency department implemented a nurse-driven routine opt-out HIV screening program. The aim of our study was to assess program uptake and opportunities to improve the program from the perspectives of emergency nurses. Emergency nurses completed a brief prediscussion questionnaire and then participated in a focus group or semi-structured one-on-one interview to elicit feedback on the routine opt-out HIV screening program...

BACKGROUND: Codon usage bias has been described for various organisms and is thought to contribute to the regulation of numerous biological processes including viral infections. HIV-1 codon usage has been previously shown to be different from that of other viruses and man. It is evident that the antiretroviral drugs used to restrict HIV-1 replication also select for resistance variants. We wanted to test whether codon frequencies in HIV-1 sequences from treatment-experienced patients differ from those of treatment-naive individuals due to drug pressure affecting codon usage bias...

BACKGROUND: Tuberculosis (TB) kills approximately two million people and infects around nine million worldwide annually. Its proper management, especially in resource-limited settings, has been hindered by the lack of rapid and easy-to-use diagnostic tests. Sputum smear microscopy remains the cheapest, readily available diagnostic method but it only identifies less than half of the patients with a HIV/TB co-infection because the bacilli would have disseminated from the lungs to other areas of the body...

BACKGROUND: Women living with HIV (WHIV) are disproportionately impacted by cervical dysplasia and cancer. The burden is greatest in low-income countries where limited or no access to screening exists. The goal of this study was to describe knowledge and intentions of WHIV towards HPV self-collection for cervical cancer screening, and to report on factors related to HPV positivity among women who participated in testing. METHODS: A validated survey was administered to 87 HIV positive women attending the Kisenyi Health Unit aged 30-69 years old, and data was abstracted from chart review...

BACKGROUND: HIV-infected individuals recently released from incarceration have suboptimal linkage and engagement in community HIV care. We conducted a study to evaluate an information and communication technology intervention to increase linkage to community care among HIV-infected persons recently involved in the criminal justice (CJ) system. Baseline characteristics including risk behaviors and HIV care indicators are reported and stratified by gender. METHODS: We recruited HIV-infected individuals in the District of Columbia jail and persons with a recent history of incarceration through community and street outreach...

BACKGROUND: HIV negative members of serostatus discordant couples are at high risk for HIV acquisition, but few interventions are in place to target them in sub-Saharan Africa. METHODS: In this study, we interviewed 28 couples, 3 times over a period of one year to understand their perceptions and attitudes around discordance, their relationship dynamics, their HIV risk behaviour, their beliefs and attitudes about antiretroviral therapy (ART) and their views of the community perceptions of discordance and treatment for HIV...

OBJECTIVES: A study of network relationships, geographic contiguity, and risk behavior was designed to test the hypothesis that all 3 are required to maintain endemicity of human immunodeficiency virus (HIV) in at-risk urban communities. Specifically, a highly interactive network, close geographic proximity, and compound risk (multiple high-risk activities with multiple partners) would be required. METHODS: We enrolled 927 participants from two contiguous geographic areas in Atlanta, GA: a higher-risk area and lower-risk area, as measured by history of HIV reporting...

HIV testing is a 'gateway' technology, enabling access to treatment and HIV prevention. Biomedical approaches to prevention, such as pre-exposure prophylaxis and treatment as prevention, require accurate and regular HIV test results. HIV testing also represents a powerful 'teachable moment' for behavioural prevention. An increasing range of HIV tests and the emergence of self-managed diagnostic technologies (e.g. self-testing) means there is now considerable diversification of when, where and how results are available to those who test...

After several years of steady decline, syphilis is reemerging globally as a public health hazard, especially among people living with human immunodeficiency virus (HIV). Syphilis resurgence is observed mainly in men who have sex with men (MSM), yet other transmission groups are affected too. In this manuscript, we study the factors associated with syphilis incidence in the Swiss HIV cohort study in the era of highly effective antiretrovirals. Using parametric interval censored models with fixed and time-varying covariates, we studied the immunological, behavioral, and treatment-related elements associated with syphilis incidence in 3 transmission groups: MSM, heterosexuals, and intravenous drug users...

INTRODUCTION: "Social big data" from technologies such as social media, wearable devices, and online searches continue to grow and can be used as tools for HIV research. Although researchers can uncover patterns and insights associated with HIV trends and transmission, the review process is time consuming and resource intensive. Machine learning methods derived from computer science might be used to assist HIV domain experts by learning how to rapidly and accurately identify patterns associated with HIV from a large set of social data...

BACKGROUND: Black men who have sex with men (MSM) are disproportionately infected with HIV and are less well retained along the HIV continuum of care. We report on the feasibility of a peer support text messaging intervention designed to increase retention in HIV care and HIV medication adherence among HIV-infected black men who have sex with men. METHODS: Based on formative research, a cell phone app was developed to support a peer-based text messaging intervention...

BACKGROUND: Retention in care is the most challenging step along the HIV care continuum. Many patients who engage in care and achieve viral suppression have care interruptions, characterized by moving in and out of care ("churn"). Poor retention has clinical consequences and contributes to new HIV transmissions, but how to predict or prevent it remains elusive. This study sought to understand the relationship between individual- and structural-level barriers, and poor retention for persons living with HIV/AIDS in Atlanta, GA...

BACKGROUND: Although Latinos living in the United States are disproportionately affected by HIV, the development, implementation, and evaluation of HIV prevention, testing, and linkage to care interventions lag behind efforts occurring in other communities. To address sociocultural barriers to testing, we developed a multilevel intervention. This study is a pilot evaluation of the individual-level component of the intervention-animated video modules that address specific barriers to HIV testing common among foreign-born Latino men...

BACKGROUND: Improved detection and linkage to care of previously undiagnosed HIV infections require innovative approaches to testing. We sought to determine the feasibility of targeted HIV testing in geographic areas, defined by continuum of care parameters, to identify HIV-infected persons needing linkage or engagement in care. METHODS: Using HIV surveillance data from Washington, DC, we identified census tracts that had an HIV prevalence >1% and were either above (higher risk areas-HRAs) or below (lower risk areas-LRAs) the median for 3 indicators: monitored viral load, proportion of persons out of care (OOC), and never in care...

CONTEXT: Improving retention in care is a key element of the National HIV/AIDS Strategy (NHAS). However, definitions for measuring retention in care are not standardized. OBJECTIVE: To compare measures of retention based on both clinic visit data and HIV laboratory surveillance data. DESIGN: Retrospective cohort study. SETTING: New York City (NYC), New York. PARTICIPANTS: We matched adult patients with HIV infection seen at the Spencer Cox Center for Health (SCC) in 2010 or 2011 with the NYC HIV Surveillance Registry...

PURPOSE OF REVIEW: More point-of-care (POC) diagnostic tests are becoming available for HIV diagnosis and treatment in resource-limited settings. These novel technologies have the potential to foster decentralized HIV care and treatment for the benefit of clinical laboratories, HIV clinics, and HIV-infected patients. There continue to be many business, technological, and operational challenges that limit product development and regulatory approval, which limits products available for the required operational and cost-effectiveness studies and delays policy adoption and implementation...

Early identification of HIV infection is of obvious benefit to patients' health, yet many remain unaware of their diagnosis, with detrimental consequences. Current guidelines suggest patients with pneumonia are offered an HIV test. Early diagnosis of HIV infection in critically ill patients within intensive care is vital in reducing mortality and morbidity. In 2015, we established automated HIV testing for patients with pneumonia admitted to our intensive care unit. Prior to our change in practice, our HIV testing rate in patients with pneumonia was 29% within two weeks of admission...

Urban slum adolescents and young adults have disproportionately high rates of HIV compared to rural and non-slum urban youth. Yet, few studies have examined youth's perceptions of the economic drivers of HIV. Informed by traditional and behavioral economics, we applied a scarcity theoretical framework to qualitatively examine how poverty influences sexual risk behaviors among adolescents and young adults. Focus group discussions with one hundred twenty youth in Kenyan's urban slums were transcribed, coded, and analyzed using interpretive phenomenology...
