OBJECTIVE: To assess intended refusal of recent graduates from three Arab dental schools to treat HIV + patients and factors associated with this intention. MATERIALS AND METHODS: In 2015, convenience samples of recent dental graduates were included from Libya, Egypt and the United Arab Emirates. Participants responded to a questionnaire assessing personal background, knowledge of oral manifestations and fluids transmitting HIV, perceived adequacy of training and self-efficacy to manage blood exposures, attitude to risk of infection, moral beliefs and willingness to treat HIV + patients...

Pulmonary disease remains a primary source of morbidity and mortality in persons living with HIV (PLWH), although the advent of potent combination antiretroviral therapy (cART) has resulted in a shift from predominantly infectious to noninfectious pulmonary complications. PLWH are at high risk for chronic obstructive pulmonary disease, pulmonary hypertension, and lung cancer even in the era of cART. The underlying mechanisms of this are incompletely understood, but recent research in both human and animal models suggest that oxidative stress, expression of matrix metalloproteinases, and genetic instability may result in lung damage which predisposes PLWH to these conditions...

BACKGROUND: Peruvian men who have sex with men (MSM) and transgender women (TGW) experience the double burden of a highly concentrated HIV epidemic with a high prevalence of alcohol use disorders (AUDs). Recent research has associated both with risky sexual behaviors, including unprotected sex, having multiple sexual partners, engaging in sex work, having recent sexually transmitted infections, and having HIV-infected partners. AUDs have also been associated in MSM/TGW with being unaware of HIV+ status...

The persistence of viruses "hidden" in a reservoir of latently infected CD4(+) T cells under antiretroviral therapy is the major obstacle to an HIV-1 cure. Recently published in Nature, two seminal studies from Descours et al. (2017) and Nishimura et al. (2017) bring hope for tracking and possibly eradicating the HIV-1 reservoir.

PURPOSE OF REVIEW: Here we discuss recently developed HIV-1 entry inhibitors that can target multiple epitopes on the HIV-1 envelope glycoprotein (Env), with an emphasis on eCD4-Ig. Some of these inhibitors are more potent and broader than any single antibody characterized to date. We also discuss the use of recombinant adeno-associated virus (rAAV) vectors as a platform for long-term expression of these inhibitors. RECENT FINDINGS: Much of the exterior of HIV-1 Env can be targeted by broadly neutralizing antibodies (bNAbs)...

PURPOSE OF REVIEW: Recent discoveries of highly potent broadly HIV-1 neutralizing antibodies provide new opportunities to successfully prevent, treat, and potentially cure HIV-1 infection. To test their activity in vivo, humanized mice have been shown to be a powerful model and were used to investigate antibody-mediated prevention and therapy approaches. In this review, we will summarize recent findings in humanized mice that have informed on the potential use of broadly neutralizing antibodies targeting HIV-1 in humans...

PURPOSE OF REVIEW: Increased body of evidence gathered over time indicate that antibodies are capable of many inhibitory mechanisms, virus neutralization being just one of them. Nonneutralizing antibodyactivities interfering with HIV replication can also lead to a decrease in viral load and even in-vivo protection. RECENT FINDINGS: It was previously believed that neutralizing antibodies can achieve sterilizing protection mainly by using their neutralization capacities against the infecting virus directly at the portal of virus entry...

PURPOSE OF REVIEW: Since 2009 many broadly neutralizing antibodies against HIV have been identified, yet there is still no vaccine capable of inducing such antibodies in humans. This review considers the early observations of HIV sera neutralization in light of more recent studies and highlights areas for future research. RECENT FINDINGS: Large clinical cohort studies using standardized neutralization assays and pseudoviruses derived from primary isolates have shown that 10-30% of HIV infections result in some level of serum neutralization breadth...

Alcohol use is particularly deleterious for HIV-infected individuals and thus accurate assessment of alcohol consumption is crucial in this population. Phosphatidylethanol (PEth) provides an objective assessment of drinking and can be compared to self-reported alcohol assessments to detect underreporting. The purpose of this study was to identify underreporting and its potential predictors in an HIV-infected sample of young Russian women. The current study examined the concordance between a quantitative measure of PEth and self-reported recent alcohol consumption in a prospective sample of HIV-infected young women (N = 204) receiving medical care in Saint Petersburg, Russia...

A fixed-dose combination tablet comprising the hepatitis C virus (HCV) NS5A inhibitor elbasvir and the HCV NS3/4A protease inhibitor grazoprevir (elbasvir/grazoprevir; Zepatier™) was recently approved for the treatment of chronic HCV genotype 1 and 4 infection in the EU and the USA. In phase III trials, 12 or 16 weeks of treatment with once-daily elbasvir/grazoprevir (fixed-dose tablet or as individual agents), taken with or without ribavirin, generally provided high rates of sustained virological response at 12 weeks (SVR12) in treatment-naive and -experienced adult patients with chronic HCV genotype 1a, 1b or 4 infection, including those with or without compensated cirrhosis, HIV co-infection, inherited blood disorders or chronic kidney disease or patients receiving opioid agonist therapy or of Japanese origin...

People living with human immunodeficiency virus (HIV) infection and receiving antiretroviral therapy now have the same life expectancy as the general population. However, they have a higher risk of atherosclerotic cardiovascular events because of a complex and polyfactorial vasculopathy, combining the effects of antiretroviral therapy, the HIV virus itself, immune activation, chronic inflammation and metabolic disturbances. Whether people living with HIV infection experience increased vascular aging compared with the general population remains controversial...

Recent advances in biomedical HIV prevention have led to optimistic projections of a dramatic worldwide reduction of new infections by 2030. This optimism is counterbalanced by concerns that the protective benefits of one such technology, HIV pre-exposure prophylaxis (PrEP), may be negated by increases in other behaviours that offset these benefits (risk compensation). To contribute to a deeper understanding of concepts of safety and risk in the context of HIV PrEP, we draw on the narrative accounts of 61 male PrEP users who participated in the inaugural PrEP demonstration project: the iPrEx open-label extension study...

BACKGROUND AND AIMS: Hepatitis C virus (HCV) incidence among HIV-positive men who have sex with men (MSM) has increased since 2000, though regional differences have been documented in recent years. We aimed to 1) estimate trends in HCV incidence among HIV-positive MSM, 2) assess the association between incidence and geographical region, age and HIV-related measurements and, 3) assess temporal changes in time from HIV seroconversion to HCV infection. METHODS: We used data from MSM with well-estimated dates of HIV seroconversion from the CASCADE Collaboration (1990-2014)...

Human immunodeficiency virus (HIV) infection remains a global pandemic. The primary driver of HIV incidence is sexual transmission between serodifferent individuals. Condoms, when used consistently and correctly, are effective at preventing sexually-transmitted HIV infections, and are considered an integral component of a comprehensive approach to HIV prevention. However, the demonstrated effectiveness of antiretroviral therapy (ART) to prevent HIV transmission, known as treatment as prevention, and of pre-exposure prophylaxis, have raised an intriguing dilemma on the necessity and additive preventive benefit of condom use among individuals in serodifferent relationships utilizing these prevention strategies...

Uganda is among the first to use the Washington Group Short Set of Questions on Disability to identify persons with disabilities in its Demographic and Health Survey. In this paper, we review the HIV Knowledge, Attitudes and Behaviour component of the 2011 Ugandan Demographic and Health Survey, analysing a series of questions comparing those with and without disabilities in relation to HIV/AIDS knowledge, attitudes and practices. We found comparable levels of knowledge on HIV/AIDS for those with and those without disabilities in relation to HIV transmission during delivery (93...

Mother-to-child transmission of HIV offers a good opportunity to study the dynamics of early viral evolution in the host environment to which the virus has partially adapted. Such studies would throw light on the unique features of the infecting viruses, which will subsequently help to design preventive or therapeutic measures against the newly infecting and evolving strains of HIV. Therefore, we undertook a study to determine the genetic divergence of proviral envelope sequences from the HIV infected infants (< 2 years)...
