Individual perceptions of HIV risk influence willingness to use pre-exposure prophylaxis (PrEP) for HIV prevention. Among men who have sex with men (MSM) and male sex workers (MSWs), temporal or episodic changes in risk behavior may influence perceived risk and PrEP acceptability over time. We investigated fluctuations in perceived HIV risk and PrEP acceptability, comparing MSWs against MSM who do not engage in sex work. We conducted 8 focus groups (n = 38) and 56 individual interviews among MSM and MSWs in Providence, RI...

The current hepatitis A outbreak in Europe is largely involving men having sex with multiple male partners. The objective of the present report was to warn teams dealing against the persistent risk of viral and bacterial sexually transmitted infection (STIs) in patients receiving HIV pre-exposure prophylaxis (PrEP). We have notified and investigated three cases of acute hepatitis A virus (HAV) infection in people receiving HIV PrEP in our clinic between December 2016 and March 2017. The patients were not epidemiologically related, had no recent travel history to HAV endemic areas, reported multiple STIs during this period and had not been vaccinated against HAV...

PURPOSE: The aim of this study was to identify sex venue-based networks among men who have sex with men (MSM) to inform HIV preexposure prophylaxis (PrEP) dissemination efforts. METHODS: Using a cross-sectional design, we interviewed MSM about the venues where their recent sexual partners were found. Venues were organized into network matrices grouped by condom use and race. We examined network structure, central venues, and network subgroups. RESULTS: Among 49 participants, the median age was 27 years, 49% were Black and 86% reported condomless anal sex (ncAS)...

I recently diagnosed my first adolescent patient with new-onset HIV. As a primary care pediatrician, these cases are rare. I cried with the shock of the initial diagnosis, just as the patient did when I told him. One of my first thoughts was how could I have served him better. He had been inconsistent with condom use, and had several partners. I had encouraged safe sex practices, told him to talk to his partners about pregnancy prevention, and screened for sexually transmitted disease nearly every time he came into my office...

Preexposure prophylaxis (PrEP) is a highly effective HIV prevention method; however, it is underutilized among women who are at risk for acquisition of HIV. Women comprise one in five HIV diagnoses in the United States, and significant racial disparities in new HIV diagnoses persist. The rate of new HIV diagnoses among black and African American women in 2015 was 16 times greater than that of white women. These disparities highlight the importance of HIV prevention strategies for women, including the use of PrEP...

The killer immunoglobulin-like receptors (KIR) are a highly diverse family of cell-surface receptors that are of importance to the effector function of Natural Killer cells. KIR have been implicated in the detection and clearance of malignantly transformed cells and in the immune-control of viruses including HIV, HCV and CMV. Recently, the mismatching of donor and recipient KIR has been demonstrated to improve success of hematopoietic stem cell transplantation treatments of leukemias. Due to the high degree of diversity amongst the KIR, a number of strategies are required for the production of recombinant protein for medical, biochemical and structural applications...

Background: Though cryptococcal meningitis (CM) is recognized as a disease of the immunocompromised, studies have implicated that it also affect immunocompetent patients. Methodology: This was a cross sectional study conducted in the Department of Medicine of a tertiary teaching institution in North India. All the patients diagnosed with CM on the basis of detection of cryptococcal antigen or the presence of capsulated budding yeast cells on India ink preparation, from April 2009 to March2015 were included in the study...

In our country, within years, despite a dramatic drop in the number of patients with malaria, a dramatic increase in the number of patients with import malaria is noteworthy. A 32-year-old male patient presented with fever, shivering, malaise, and loss of appetite. He had travelled to West Africa. Laboratory findings were as follows: hemoglobin: 8.8 g/dL and anti-HIV: positive. Microscopic examinations of thin blood smears and thick blood preparations revealed widespread trophozoites. The presence of double-dotted ring forms and banana-shaped gametocytes resulted in Plasmodium falciparum malaria being diagnosed...

Though many women in need of access to HIV preventive regimes are pregnant, there is a dearth of data to guide these care decisions. While oral pre-exposure prophylaxis (PrEP) has been shown to prevent HIV infection in numerous high-risk populations, pregnant women have been excluded from all major prospective trials. We propose for ethical examination a theoretical trial-a prospective, observational study of PrEP for pregnant women at risk for HIV in sub-Saharan Africa-highlighting an ethical tradeoff that characterizes issues faced for advancing research in pregnancy...

The exclusion of pregnant women from health research remains a significant challenge globally. In settings where cultural traditions and gender norms support a more restricted decision-making role for women in general, little is known about the attitudes of male partners toward the inclusion of women in research during pregnancy. Understanding the expectations of both men and women in such cultural settings offers an opportunity to engage and address local ethical concerns to improve women's access to research during pregnancy and enhance intervention development...

Adherence challenges with oral pre-exposure prophylaxis have stimulated interest in alternate modes of administration including long-acting injections. We conducted 30 in-depth interviews with 26 male trial participants and 4 clinical providers in a Phase IIa study (ÉCLAIR) evaluating the use of long-acting cabotegravir (CAB-LA) injections in New York and San Francisco. Interviews exploring attitudes and experiences with CAB-LA were audiotaped, transcribed, and analyzed using thematic content analysis. Despite a high frequency of some level of side effects, almost all participants reported being interested in continuing with CAB-LA, versus a daily oral, due to its convenience and the perceived advantage of not worrying about adhering to pills...

The integrase (IN) protein of the retrovirus prototype foamy virus (PFV) is a model enzyme for studying the mechanism of retroviral integration. Compared to IN from other retroviruses, PFV IN is more soluble and more amenable to experimental manipulation. Additionally, it is sensitive to clinically relevant human immunodeficiency virus (HIV-1) IN inhibitors, suggesting that the catalytic mechanism of PFV IN is similar to that of HIV-1 IN. IN catalyzes the covalent joining of viral complementary DNA (cDNA) to target DNA in a process called strand transfer...

Pre-exposure prophylaxis (PrEP) remains an under-utilized HIV prevention tool among men who have sex with men (MSM). To more comprehensively elucidate barriers and facilitators to PrEP use among US MSM, we conducted a systematic review of peer-reviewed published articles and content analysis of online posts about PrEP. We searched peer-reviewed databases (Medline, Web of Science, Google Scholar) using MESH headings and keywords about PrEP and/or HIV prevention from 2005 to 2015. We included original studies among MSM in the US that reported on barriers, facilitators, or other factors related to PrEP use...

Gay, bisexual, and other men who have sex with men (GBM) are disproportionately affected by the HIV epidemic. Despite the promise of pre-exposure prophylaxis (PrEP) in reducing HIV transmission risk, barriers for uptake and persistence exist. We sought to identify whether GBM in a nationwide cohort who have not yet initiated PrEP (n = 906) would prefer to get PrEP-related care from a primary care provider (PCP) compared to a specialist clinic or provider. We then sought to identify their level of interest and factors associated with preference for using home-based PrEP services (i...

Microglia and macrophages are the main non-neuronal subsets of myeloid origin in the brain, and are critical regulators in neurodegenerative disorders, where inflammation is a key factor. Since HIV infection results in neurological perturbations that are similar to those in aging, we examined microglial and infiltrating myeloid subsets in the search for changes that might resemble the ones in aging. For that, we used the SIV infection in rhesus macaques to model neuroAIDS. We found that Sirt-1, a molecule that impacts survival and health in many models, was decreased in cell preparations containing a majority of microglia and myeloid cells from the brain of infected macaques...

Human immunodeficiency virus (HIV) has now transformed into a manageable chronic condition. Highly active antiretroviral therapy (HAART) has proven efficacious at controlling the disease progression. Based on compelling evidence, the Department of Health and Human Services (DHHS) and the Infectious Disease Society of America (IDSA) developed guidelines for the management of persons infected with HIV. However, there are approximately 50 000 new cases of HIV in the United States each year. In this article, we review proactive methods to reduce the transmission of HIV, which include reinforcing patient education, gel-coated condoms that destroy HIV, HIV vaccinations, and adequately utilizing pre-exposure prophylaxis (PrEP), and post-exposure prophylaxis (PEP)...

BACKGROUND: Misuse of prescription opioid analgesics (POA) has increased dramatically in the US, particularly in non-urban areas. We examined injection practices among persons who inject POA in a rural area that experienced a large HIV outbreak in 2015. METHODS: Between August-September 2015, 25 persons who injected drugs within the past 12 months were recruited in Scott County, Indiana for a qualitative study. Data from in-depth, semi-structured interviews were analyzed...

PURPOSE OF REVIEW: The antiviral agent tenofovir is highly effective for the treatment of HIV and hepatitis B virus infections, and the older prodrug tenofovir disoproxil fumarate (TDF) is also a component of daily preexposure prophylaxis (PrEP) to reduce the risk of HIV infection in high-risk populations. Although TDF is well tolerated, the potential for kidney and bone toxicity has important implications for public health given the large number of individuals exposed to TDF worldwide...
