Co-Occurring HIV Risk Behaviors among Males Entering Jail
HIV risk co-occurring behaviors correctional facilities male detainees
2013/4/28
This paper examines the pattern of HIV risk behaviors among male jail detainees. From multivariate analyses of baseline data from an HIV intervention study of ours, we find that: (1) cocaine use, hero...

In most countries CD4+ cell counts are still used for deciding when to start HIV-positive people on anti-retroviral therapy. However, various CD4+ thresholds, 200, 350 or 500/ μL, are chosen arbitrar...

Hepatitis C virus (HCV) coinfection has become one of the most
challenging clinical situations to manage in HIV-infected patients.
Recently the effect of HCV coinfection on HIV dynamics following

We introduce a new version of forward stepwise regression. Our
modification finds solutions to regression problems where the selected
predictors appear in a structured pattern, with respect to a pre...

HIV dynamical models are often based on non-linear systems
of ordinary di erential equations (ODE), which do not have analytical
solution. Introducing random e ects in such models leads to very chal...

A virologic marker, the number of HIV RNA copies or viral load,
is currently used to evaluate antiretroviral (ARV) therapies in AIDS
clinical trials. This marker can be used to assess the ARV potenc...

A two-sex Basic Reproduction Number (BRN) is used to investigate the conditions
under which the Human Immunodeficiency Virus (HIV) may spread through
heterosexual contacts in Sub-Saharan Africa. (Th...
