BACKGROUND: Cystic lymphoid hyperplasia (CLH) describes benign salivary lymphoepithelial cysts with a strong link to human immunodeficiency virus (HIV) infection and acquired immunodeficiency syndrome (AIDS). The pathogenesis is related to ductal dilatation of entrapped salivary elements due to intranodal HIV-associated atypical lymphoid hyperplasia. Very little is known about the immunophenotypic profile of this entity. AIM: This study aims to describe the immunopathological features of a series of CLH cases in HIV-positive patients to clarify the etiopathogenesis...

In longitudinal AIDS studies, it is of interest to investigate the relationship between HIV viral load and CD4 cell counts, as well as the complicated time effect. Most of common models to analyze such complex longitudinal data are based on mean-regression, which fails to provide efficient estimates due to outliers and/or heavy tails. Quantile regression-based partially linear mixed-effects models, a special case of semiparametric models enjoying benefits of both parametric and nonparametric models, have the flexibility to monitor the viral dynamics nonparametrically and detect the varying CD4 effects parametrically at different quantiles of viral load...

BACKGROUND: Virological success (VS) and immunological reconstitution (IR) of antiretroviral-naïve HIV-1 infected patients with pre-therapy viral load (VL) >500,000 copies/mL was assessed after 12 months of treatment according to initial drug-class regimens. METHODS: An observational multicenter retrospective study was performed. VS was defined as the first VL <50 copies/mL from treatment start. IR was defined as an increase of at least 150 CD4+ T-lymphocytes from treatment start...

INTRODUCTION: Established by the Affordable Care Act, the National Quality Strategy (NQS) is the national policy goals aimed at improving the quality of health care for all Americans. The NQS established six priorities to provide better, more affordable care for individuals and communities. This is the first analysis of data on the NQS and access measures that focus on sex differences, health conditions, trends, and disparities. METHODS: Measures from the 2015 National Healthcare Quality and Disparities Report (QDR) for the four National Quality Strategy priorities (Patient Safety, Person Centered Care, Effective Treatment and Healthy Living), access to care, and health conditions for women were compared to measures for men...

OBJECTIVE: HIV/AIDS is generally associated with dyslipidemia and oxidative imbalance, which are caused by the infection itself and by antiretroviral therapy (ART). The flavonoids, found in cocoa and yerba mate, have antioxidant and hypolipidemic properties. The aim of this study was to evaluate the effects of the consumption of dark chocolate and mate tea on the lipid profiles of individuals with HIV/AIDS who are undergoing ART. METHODS: A randomized, double-blind, placebo-controlled crossover clinical trial was conducted with 92 patients receiving ART for ≥6 mo and with viral suppression...

The prevention of HIV and AIDS, especially amongst young people, is very important, as they are the future leaders. South Africa carries a high burden of the HIV and AIDS disease, and efforts at the prevention of the disease need to be intensified. University students are also at risk, and prevention efforts need to be intensified to ensure that students graduate and enter the world of work to become productive citizens. Failure to pay attention to preventative behaviour amongst university students may have negative socio-economic consequences for the country...

Cryptococcus neoformans is an opportunistic pathogen responsible for the AIDS-defining illness, cryptococcal meningitis. During the disease process, entry of cryptococcal cells into the brain is facilitated by virulence factors that include urease enzyme activity. A novel species of an Emmonsia-like fungus, recently named Emergomyces africanus, was identified as a cause of disseminated mycosis in HIV-infected persons in South Africa. However, in contrast to C. neoformans, the enzymes produced by this fungus, some of which may be involved in pathogenesis, have not been described...

Gay, bisexual, and other men who have sex with men (collectively referred to as MSM) represent approximately 2% of the U.S. population (1), yet in 2015, MSM accounted for 70% of all diagnoses of human immunodeficiency virus (HIV) infection, including 3% who also were persons who inject drugs (2). During 2008-2014, incidence of HIV infection decreased for groups in all transmission categories except MSM (3). Testing, linkage to and retention in care, and viral suppression are important in reducing HIV transmission...

I examine the legacies of Soviet public health policy and the socialist health care system and trace how the Soviet past figures in contemporary Russian policymaking and debates about drug use, HIV, and abortion. Drug policies and mainstream views of HIV reflect continuities with key aspects of Soviet-era policies, although political leaders do not acknowledge these continuities in justifying their policies. In abortion policy, by contrast, which is highly debated in the public realm, advocates represent themselves as differing from Soviet-era policies to justify their positions...

African Americans are disproportionately affected by HIV/AIDS and other sexually transmitted infections relative to other racial groups. Although substance use has been linked to risky sexual behavior, the understanding of how these associations develop over the life course remains limited, particularly the role of social bonds. This study uses structural equation modeling to examine pathways from adolescent substance use to young adult sexual risk, substance problems, and social bonds and then to midlife risky sexual behavior among African American men and women, controlling for childhood confounders...

Psychiatric bed capacity has decreased nationally with an impact on the number and the types of patients admitted to acute in-patient units. Acute residential programs provide alternatives to hospitals for patients with problems that do not meet criteria for admission. However, these settings may not have resources to respond to the medical co-morbidities associated with severe mental illness. To understand the medical needs of patients in these settings, this research examined data from a nurse-managed primary care outreach service...

Modern antiretroviral treatment belongs to the greatest success of current medicine. HIV infection has gone from a death sentence to a manageable chronic disease which develops several decades. Thanks to treatment advances, people with HIV can and do live long and full lives. In the last two decades, the incidence AIDS defining illnesses have been dramatically reduced especially opportunistic infections and malignancies, whereas the role of non-infection comorbidities has risen than age-matched HIV uninfected adults...

Previous studies in our laboratory showed that the RNA debranching enzyme (DBR1) is not required for early steps in HIV cDNA formation, but is necessary for synthesis of intermediate and late cDNA products. To further characterize this effect, we evaluated the topology of the 5' end of the HIV-1 RNA genome during early infection with and without inhibition of DBR1 synthesis. Cells were transfected with DBR1 shRNA followed 48 hours later by infection with an HIV-1 derived vector containing an RNase H deficient reverse transcriptase...

A thorough understanding of the role of HIV intra-host evolution in AIDS pathogenesis has been limited by the need for longitudinally sampled viral sequences from the vast target space within the host, which are often difficult to obtain from human subjects. CD8+ lymphocyte-depleted macaques infected with simian immunodeficiency virus (SIV) provide an increasingly utilized model of pathogenesis due to similar clinical manifestations as HIV-1 infection and AIDS progression, as well as characteristic rapid disease onset...

The development of an effective AIDS vaccine has been challenging due to viral genetic diversity and the difficulty in generating broadly neutralizing antibodies (bnAbs). Here, we engineered trispecific antibodies (Abs) that allow a single molecule to interact with three independent HIV-1 envelope determinants: 1) the CD4 binding site, 2) the membrane proximal external region (MPER) and 3) the V1V2 glycan site. Trispecific Abs exhibited higher potency and breadth than any previously described single bnAb, showed pharmacokinetics similar to human bnAbs, and conferred complete immunity against a mixture of SHIVs in non-human primates (NHP) in contrast to single bnAbs...

CD8+ T-cell responses exert strong suppressive pressure on HIV replication and select for viral escape mutations. Some of these major histocompatibility complex class I (MHC-I)-associated mutations result in reduction of in vitro viral replicative capacity. While these mutations can revert after viral transmission to MHC-I-disparate hosts, recent studies have suggested that these MHC-I-associated mutations accumulate in populations and make viruses less pathogenic in vitro. Here, we directly show an increase in the in vivo virulence of an MHC-I-adapted virus serially-passaged through MHC-I-mismatched hosts in a macaque AIDS model despite a reduction in in vitro viral fitness...
