Journal ArticleDOI
Testing the number of components in a normal mixture
TL;DR: In this article, it was shown that the likelihood ratio statistic based on the Kullback-Leibler information criterion of the null hypothesis that a random sample is drawn from a k 0 -component normal mixture distribution against the alternative hypothesis that the sample was drawn from an k 1 -component normalized mixture distribution is asymptotically distributed as a weighted sum of independent chi-squared random variables with one degree of freedom, under general regularity conditions.
Journal ArticleDOI
A prospective study of adherence and viral load in a large multi-center cohort of HIV-infected women.
Andrea A. Howard,Julia H. Arnsten,Yungtai Lo,David Vlahov,David Vlahov,Josiah D. Rich,Paula Schuman,Valerie E. Stone,Dawn K. Smith,Ellie E. Schoenbaum +9 more
TL;DR: Antiretroviral adherence is not stable over time in HIV-infected women, and interventions aimed at monitoring and improving long-term adherence in women are urgently needed.
Journal ArticleDOI
Decreased bone mineral density and increased fracture risk in aging men with or at risk for HIV infection.
Julia H. Arnsten,Ruth Freeman,Andrea A. Howard,Michelle Floris-Moore,Yungtai Lo,Robert S. Klein +5 more
TL;DR: HIV infection is independently associated with modestly reduced BMD in aging men, and decreased BMD is associated with increased fracture risk.
Journal ArticleDOI
Bacterial Pneumonia, HIV Therapy, and Disease Progression among HIV-Infected Women in the HIV Epidemiologic Research (HER) Study
Rakhi Kohli,Yungtai Lo,Peter Homel,Timothy P. Flanigan,Lytt I. Gardner,Andrea A. Howard,Anne Rompalo,Galina Moskaleva,Paula Schuman,Ellie E. Schoenbaum +9 more
TL;DR: High rates of bacterial pneumonia persist among HIV-infected women, and although HAART and TMP-SMX treatment decreased the risk, bacterial pneumonia was associated with an accelerated progression to death.
Journal ArticleDOI
HIV Infection, Drug Use, and Onset of Natural Menopause
Ellie E. Schoenbaum,Diana Hartel,Yungtai Lo,Andrea A. Howard,Michelle Floris-Moore,Julia H. Arnsten,Nanette Santoro +6 more
TL;DR: It is shown that HIV infection and immunosuppression are associated with an earlier age at the onset of menopause in HIV-infected women and their risk of osteoporosis and heart disease requires further study.
