Comparison of neuropsychological performance between AIDS-free injecting drug users and homosexual men.

We performed a cross-sectional comparison of the baseline neuropsychologic performance of 107 injecting drug users and 230 homosexual men participating in two longitudinal studies. Cognitive tests measured attention, memory and psychomotor speed. Using multiple regression modelling, the analysis adjusted for age, IQ score, race, six-month history of alcohol, cocaine, opiates and marijuana use, HIV serostatus and CD4+ lymphocyte count.

Impact of on-site social work services on the documentation of client and family-centered information: the experience of Ryan White CARE Act (Title IV) pediatric program sites in Maryland.

Background: The purpose of this study is to (1) describe client and maternal demographic, social, and medical characteristics of pediatric clients receiving medical and social services at Ryan White (Title IV) program sites, and (2) determine the impact of on-site social work services in documenting client and family-related information used to assess the psychosocial needs of the families affected by human immunodeficiency syndrome and acquired immunodeficiency syndrome (HIV/AIDS).

Methods: We studied infants born to known HIV-infected women who received HIV-related medical services at a federally funded Title IV Ryan White CARE Act provider site in Maryland. Eligibility criteria included < 24 months of age at time of initial clinic visit, a history of birth to a known HIV-infected woman, and a minimum of one comprehensive clinical visit for medical evaluation at a selected Title IV provider site.

Racial differences in rate of CD4 decline in HIV-1-infected homosexual men.

Objective: To determine whether racial differences exist in the rate of CD4 lymphocyte decline in HIV-1-infected homosexual men.

Design: Prospective cohort study.

Study Population: Non-Hispanic white (n = 321) and black (n = 102) HIV-1-seropositive homosexual and bisexual men were recruited from the Baltimore/Washington, DC metropolitan areas between 1984-1985 and 1987-1990, and evaluated semiannually.

Weight loss prior to clinical AIDS as a predictor of survival. Multicenter AIDS Cohort Study Investigators.

In this analysis the aim was to determine the independent effect of moderate to severe weight loss prior to an AIDS diagnosis on survival after AIDS. The study was conducted as part of the Multicenter AIDS Cohort Study (MACS), a longitudinal study of HIV-1-seropositive gay or bisexual men. Measured weight and self-reported weight loss data were collected semiannually from 1984 through 1993.

Beta 2-microglobulin and other early predictors of human immunodeficiency virus type 1-related wasting.

The objective of this study was to determine whether beta 2-microglobulin, neopterin, nutritional status, clinical status, immunosuppression, and hematologic status are predictors of human immunodeficiency virus (HIV)-related wasting and wasting syndrome. In addition, we aimed to determine which factors are early predictors and which are late predictors of wasting. For this cohort study of HIV-1-seropositive men seen semiannually from 1984 to 1991, a nested case-control design was used to analyze the predictive value of independent variables collected at baseline (first study visit for the seropositive cohort, first seropositive visit for seroconverters), 12 to 18 months prior, 6 to 12 months prior, and less than 6 months prior to the time at which case patients and control subjects were identified.
