PURPOSE To study the effect of contact lens (CL) power on retinal nerve fiber layer (RNFL) thickness measurements using optical coherence tomography (OCT). METHODS Cross-sectional study on 15 healthy subjects. Peripapillary RNFL thickness was measured using time-domain OCT without CL and with CL of different powers (+4 D, +10, -4D, and -10 D), and again(More)
Background. CD4+ T-lymphocyte monitoring is not routinely available in most resource-limited settings. We investigated predictors of time to CD4+ T-lymphocyte recovery in HIV-infected children on highly active antiretroviral (HAART) at Korle-Bu Teaching Hospital, Ghana. Methods. Time to CD4+ T-lymphocyte recovery was defined as achieving percent CD4+(More)
Central nervous system (CNS) inflammation is a mediator of brain injury in HIV infection. To study the natural course of CNS inflammation in the early phase of infection, we analyzed longitudinal levels of soluble and cellular markers of inflammation in cerebrospinal fluid (CSF) and blood, beginning with primary HIV-1 infection (PHI). Antiretroviral-naïve(More)
OBJECTIVE The childhood obesity epidemic has been accompanied by an increasing prevalence of type 2 diabetes (T2D), particularly in minority children. Twenty to thirty percent of obese youth have "prediabetes," a precursor to diabetes marked by insulin resistance, β-cell dysfunction, and impaired glucose tolerance. The Diabetes Prevention Program(More)
—In cognitive radio networks (CRNs), dynamic spectrum access has been demonstrated as an effective way to improve the spectrum utilization. Spectrum holes can be exploited not only in certain time slots or frequency bands, but also at particular locations. In relay assisted CRNs, one relay at a certain location can help to identify and provide different(More)
BACKGROUND The optimal treatment of malaria in human immunodeficiency virus (HIV)-infected children requires consideration of critical drug-drug interactions in coinfected children, as these may significantly impact drug exposure and clinical outcomes. METHODS We conducted an intensive and sparse pharmacokinetic/pharmacodynamic study in Uganda of the most(More)
BACKGROUND Early intervention services for psychotic disorders optimally interlock strategies to deliver: (i) Early Detection (ED) to shorten the time between onset of psychotic symptoms and effective treatment (i.e. Duration of Untreated Psychosis, DUP); and (ii) comprehensive intervention during the subsequent 2 to 5 years. In the latter category, are(More)
