View clinical trials related to HIV-exposed Uninfected.
Filter by:Globally, over 1 million babies are born to mothers with HIV each year. With the advent of prenatal antiretroviral therapy, up to 98% of these individuals may be HIV-exposed uninfected (HEU). A growing literature suggests that in utero HIV exposure - even in the absence of subsequent infection - may be associated with adverse health outcomes in infancy and childhood. However, there is little information about the long-term health implications of in utero HIV exposure later in life, such as into adulthood. In this study, for the first time, we seek to prospectively evaluate metabolic and immune indices among HEU young adults as compared to well-matched HIV-unexposed uninfected controls. This study serves as a necessary first step toward optimizing clinical care for this expanding and aging HEU population, including the implementation of novel screening and prevention strategies.
The investigators will use Brain Power Games or Village Builder, two different MSU-developed computer-based learning games for children on Tablets, as a neurocognitive "stress test" or medical "challenge" test, in order to evaluate brain/behavior functional integrity in HIV-affected children. This dual use of BPG is a key innovative feature. Each of the 5 core BPG games lasts 10 minutes and trains fine motor, monitoring/attention, visual/auditory working memory, spatial navigational learning. Village Builder (VB) uses similar graphics as BPG, but is a pro-social "world-building" game where children gather and protect resources to build a village. thus VB emphasizes planning/reasoning (executive function or EF) neurocognitive abilities, while BPG emphasizes attention, memory, and learning tasks. In As an African child plays with BPG or VB on a touch-screen tablet, we will use games as a dynamic window into the child's developing brain and EF-based frontal lobe development Aim 1. Evaluate concurrent and predictive validity of BPG static (baseline) and dynamic (during 12 training sessions) cognitive assessments Aim 2. Compare the validity of BPG static and dynamic assessments Aim 3. Test the sensitivity of dynamic assessment to learning loss over time by evaluating how much BPG and/or VB performance gains diminish during a 6-month absence of training The investigator's central hypothesis is that the BPG and VB performance gains (dynamic assessment) will explain the additional variation in the gold-standard measures at time points after static (baseline) assessment, and more effectively capture the effects of HIV/ARV exposure and treatment across HIV affected cohorts (HIV, HEU, HUU) of children in Uganda and Malawi.
