Self-report is typically used to differentiate between asymptomatic neurocognitive impairment (ANI) and mild neurocognitive disorder (MND) in the assessment of HIV-associated neurocognitive disorders (HAND). Yet, it is unclear whether the lack of self-reported functional impairments in individuals with ANI is indicative of a genuine absence of functional impairment, or of inaccurate self-reports. In the present study, we examined the relationship between previously validated self-report (patient's assessment of own functioning inventory; instrumental activities of daily living inventory) and performance-based (the Texas Functional Living Scale) measures of functional abilities in 112 virologically-controlled HIV-infected, and 40 well-matched, HIV-uninfected participants...

Our aim was to examine the clinical relevance of white matter hyperintensities (WMH) in HIV. We used an automated approach to quantify WMH volume in HIV seropositive (HIV+; n = 65) and HIV seronegative (HIV-; n = 29) adults over age 60. We compared WMH volumes between HIV+ and HIV- groups in cross-sectional and multiple time-point analyses. We also assessed correlations between WMH volumes and cardiovascular, HIV severity, cognitive scores, and diffusion tensor imaging variables. Serostatus groups did not differ in WMH volume, but HIV+ participants had less cerebral white matter (mean: 470...

BACKGROUND: Infant HIV infection is associated with delayed milestone attainment. The extent to which effective antiretroviral therapy (ART) prevents these delays is not well defined. METHODS: Ages at attainment of milestones were compared between HIV-infected (initiated ART by age <5 months), and HIV-unexposed uninfected (HUU) infants. Kaplan Meier analyses were used to estimate and compare (log-rank tests) ages at milestones between groups. Adjusted analyses were performed using Cox proportional hazards models...

Although rates of crystal methamphetamine use in the United States have fallen from their peak in the mid-2000s, use remains a major public health concern, which disproportionately affects gay and bisexual men (GBM). It poses a particular challenge for HIV-positive men, for whom it has been linked to medication adherence problems as well as compromised immune function. Although the information, motivation, and behavioral skills (IMB) model has been widely used to conceptualize health behavior, little is known about GBM's initial levels of information, motivation, and behavioral self-efficacy to improve HIV medication adherence and to reduce crystal methamphetamine use at the outset of treatment...

Despite improved survival due to combination antiretroviral therapy (cART), youth with perinatally-acquired HIV (PHIV) show cognitive deficits and developmental delay at increased rates. HIV affects the brain during critical periods of development, and the brain may be a persistent reservoir for HIV due to suboptimal blood brain barrier penetration of cART. We conducted structural magnetic resonance imaging (sMRI) and cognitive testing in 40 PHIV youth (mean age=16.7 years) recruited from the NIH Pediatric HIV/AIDS Cohort Study (PHACS) who are part of the first generation of PHIV youth surviving into adulthood...

This study of a prospective and cross-sectional nature compared the motor and cognitive development of HIV-exposed and unexposed infants in their first 18months of age. 40 infants exposed to HIV and antiretroviral therapy (Experimental Group - EG) and 40 unexposed infants (Control Group - CG) participated in the study. They were divided into four age groups of 4, 8, 12 and 18months old, with 10 infants from EG and 10 from CG in each group. The infants were evaluated once on motor and cognitive development by the Bayley Scale of Infant and Toddler Development...

Infection with human immunodeficiency virus (HIV) is associated with neuroimaging alterations. However, little is known about the topological organization of whole-brain networks and the corresponding association with cognition. As such, we examined structural whole-brain white matter connectivity patterns and cognitive performance in 29 HIV+ young adults (mean age = 25.9) with limited or no HIV treatment history. HIV+ participants and demographically similar HIV- controls (n = 16) residing in South Africa underwent magnetic resonance imaging (MRI) and neuropsychological testing...

PURPOSE: The goal of the current study was to explore visual function in virally suppressed HIV patients undergoing combined antiretroviral therapy (cART) by using pattern-reversal and motion-onset visual evoked potentials (VEPs). METHODS: The pattern-reversal and motion-onset VEPs were recorded in 20 adult HIV+ patients with a mean age of 38 years and CD4 cell counts ≥230 × 10(6) cells/L of blood. RESULTS: Nine out of 20 patients displayed VEP abnormalities...

Institutions are not necessarily good environments for children. In the face of challenges such as HIV, Ebola, poverty, conflict and disaster the numbers have grown rather than reduced. Some countries have closed institutions down -driven by findings that cognitive developmental delay is associated with institutional care. Yet insight into abuse and violence within institutionalised settings is neglected. Maltreatment -violence and abuse -may be an issue. This systematic review series addresses violence and abuse experiences in institutionalised care, exploring firstly the frequency of abuse/violence in institutions, secondly any interventions to reduce such violence or abuse and thirdly the perpetrators of such violence or abuse...

Effective combination antiretroviral therapy (cART) has lead to a significant reduction in the prevalence and incidence of central nervous system (CNS) HIV-associated brain disease, particularly CNS opportunistic infections and HIV encephalitis. Despite this, cognitive deficits in people living with HIV, also known as HIV-associated neurocognitive disorders (HAND) have become more prevalent in recent years. The pathogenesis of HAND is likely to be multifactorial, however recent evidence suggests that brain microglial activation is the most likely pathogenic mechanism...

INTRODUCTION: The current study sought to determine the optimal impairment rating definition for a new HIV-associated neurocognitive disorder (HAND) screening procedure as compared to standard neuropsychological testing. METHOD: A total of 55 HIV-infected (HIV+; 19% AIDS; 87% on combination antiretroviral therapy, cART; 80% plasma undetectable) and 22 demographically comparable HIV-uninfected (HIV-) control adults (all male) enrolled in an urban Australian primary care cohort study completed the CogState computerized cognitive screen, a standard independence in activities of daily living (ADL) questionnaire, and a standard neuropsychological test battery...

OBJECTIVE: For individuals with neurologic disorders, self-awareness of cognitive impairment is associated with improved treatment course and clinical outcome. However, methods for assessment of levels of self-awareness are limited, and most require collateral information, which may not be readily available. Although distortions in self-awareness are most often associated with low cognitive ability, the frequently mixed pattern of cognitive strengths and deficits in individuals with neurologic disorders complicates assessment...

BACKGROUND: Cryptococcus can cause meningoencephalitis (CM) among previously healthy non-HIV adults. Spinal arachnoiditis is under-recognized, since diagnosis is difficult with concomitant central nervous system (CNS) pathology. METHODS: We describe 6 cases of spinal arachnoiditis among 26 consecutively recruited CM patients with normal CD4 counts who achieved microbiologic control. We performed detailed neurological exams, cerebrospinal fluid (CSF) immunophenotyping and biomarker analysis before and after adjunctive immunomodulatory intervention with high dose pulse corticosteroids, affording causal inference into pathophysiology...

BACKGROUND: University students' substance abuse and risky sex contribute to sexually transmitted diseases (STDs). PURPOSE: We develop and empirically test a formative theoretical model of sexual temptation involving substance abuse (cigarettes, alcohol, and marijuana), safe sexual behavior (use of condom/barrier for oral and vaginal intercourse), risky sexual behavior (unprotected sex and multiple sexual partners), and STDs: gonorrhea, HIV, and genital herpes. We simultaneously explore these constructs, controlling membership in social groups (fraternity/sorority, varsity athlete, and club sports) and perceived norm of substance abuse...

Although the role of CCR5 in immunity and in HIV infection has been studied widely, its role in neuronal plasticity, learning and memory is not understood. Here, we report that decreasing the function of CCR5 increases MAPK/CREB signaling, long-term potentiation (LTP), and hippocampus-dependent memory in mice, while neuronal CCR5 overexpression caused memory deficits. Decreasing CCR5 function in mouse barrel cortex also resulted in enhanced spike timing dependent plasticity and consequently, dramatically accelerated experience-dependent plasticity...

BACKGROUND: HIV-associated neurocognitive disorders (HAND) are widely present among people living with HIV. Especially its milder forms, asymptomatic neurocognitive impairment (ANI) and mild neurocognitive disorder (MND), remain highly prevalent worldwide. Diagnosing these conditions is subject to a time and resource consuming neuropsychological assessment. Selecting patients at a higher risk of cognitive impairment by using a simple but effective screening tool helps to organise access to further neuropsychological diagnosis...

BACKGROUND: Recent work on patient-reported outcomes (PROs) focuses on precise, brief measures, which generally convey little about what an individual's rating actually means. Individual differences in appraisal are important and relevant to PRO research. This paper highlights the advantages of integrating appraisal assessment into clinical research. METHODS: The most comprehensive method for assessing appraisal, the quality of life (QOL) Appraisal Profile, includes open-ended and multiple choice questions to assess four appraisal parameters: frame of reference, sampling of experience, standards of comparison, and combinatory algorithm...

Accumulating evidence suggests that viewing sexually explicit media (SEM; i.e., pornography) may be related to the sexual behaviors of men who have sex with men (MSM). Furthermore, stereotypical depictions of Black/African American MSM engaging in sexual risk behaviors in SEM may serve to normalize condomless sex, reinforce low peer norms around condom use, and facilitate HIV risk taking among Black/African American MSM. Despite this evidence, very little is known about the correlates of SEM consumption among Black/African American MSM, including HIV risk behaviors and their relation to preferences for viewing condomless sex in SEM...
