Using a sample of 280 Puerto Rican drug users with a history of incarceration residing in Massachusetts, we explore whether a significant association exists between social and economic factors (maintaining social network contacts, receiving public assistance) and lifetime incarceration. Analysis of survey data using regression methods shows that respondents who live in their own home, receive public assistance, and have recent familial contact are significantly less likely to have been incarcerated in the past 6 months. Among study participants, men and those who initiated heroin use at younger ages are more likely to have greater lifetime incarceration totals.

This study examined the relationship between substance abuse treatment use, health services use, HIV status, and emergency room/hospital use for 507 injection drug users (IDUs). Logistic regression models showed that mental health status, severity of drug use and private health insurance were significantly associated with having used emergency room/hospital services in the past six months. History of substance abuse treatment use, positive HIV/AIDS diagnosis, mental health service use, ethnic/racial background, gender, age, education and homelessness were not significant at either the bivariate or the multivariate level.

Barriers to effective diagnostic testing for human immunodeficiency virus type 1 (HIV-1) infection can be reduced with simple, reliable, and rapid detection methods. Our objective was to determine the accuracy, sensitivity, and specificity of a new rapid, lateral-flow immunochromatographic HIV-1 antibody detection device. Preclinical studies were performed using seroconversion, cross-reaction, and interference panels, archived clinical specimens, and fresh whole blood.
