Prospective memory (PM), "remembering to remember," has been linked to important functional outcomes in adults. Studies of PM in children and adolescents would benefit from the development and validation of developmentally appropriate clinical measures with known psychometric properties. The Prospective Memory Assessment for Children & Youth (PROMACY), a performance-based measure of PM, was developed for the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol, Memory and Executive Functioning Substudy, and includes Summary, Time-, and Event-based scores derived from eight trials with an ongoing word search task.

Introduction: Western-constructed neuropsychological tests have been used in low and middle income countries to assess the impact of HIV/AIDS and other chronic illnesses. We explore using such instruments cross-culturally in a sub-Saharan Africa setting.
Methods: IMPAACT P1104S was a two-year observational study carried out at six clinical sites (South Africa- 3 sites, Malawi, Uganda and Zimbabwe) to assess and compare neuropsychological outcomes in three cohorts of children 5-11 years of age: HIV-infected (HIV), HIV-exposed but uninfected (HEU) and HIV unexposed and uninfected (HU).
Objective And Design: Children with HIV infection (HIV+) are at neuropsychological risk, but few studies have evaluated this at multiple sites in low-income and middle-income countries. We compared neuropsychological outcomes at enrollment (>5 years age) among HIV+, HIV perinatally exposed uninfected (HEU), and HIV unexposed uninfected (HUU) children from four sub-Saharan countries.
Methods: IMPAACT P1060 compared nevirapine versus lopinavir/ritonavir-based antiretroviral treatment (ART) in HIV-infected children 6-35 months of age.
Youth with perinatal HIV infection (PHIV) are at increased risk for neurocognitive impairment (NCI). Prospective memory (PM) is a complex neurocognitive function that has been shown to be impaired in adults with HIV disease and independently associated with poorer daily living skills, including medication nonadherence. The current study sought to determine the presence and extent of PM deficits in youth with PHIV.

Understanding how medication responsibility, executive functions (EFs) and adaptive functioning (AF) influence adherence may help prepare adolescents for transition to adulthood.
Methods: Participants included PHIV children and adolescents 7-16 years of age enrolled in the Pediatric HIV/AIDS Cohort Study Adolescent Master Protocol, who were prescribed antiretroviral medications.
Background: Little is known regarding effects of perinatally acquired HIV infection (PHIV) on longitudinal change in memory and executive functioning (EF) during adolescence despite the importance of these skills for independence in adulthood.
Methods: PHIV (n = 144) and perinatally HIV-exposed uninfected youth (PHEU, n = 79), ages 12-17, completed standardized tests of memory and EF at baseline and 2 years later. Changes from baseline for each memory and EF outcome were compared between PHEU and PHIV youth with (PHIV/C, n = 39) and without (PHIV/non-C, n = 105) history of CDC class C (AIDS-defining) diagnoses.
Background: Perinatally acquired HIV (PHIV) confers risk for neurocognitive impairment, which potentially affects school performance and functional independence of infected children. In this study, we examined the associations of 2 key neurocognitive domains, memory and executive function (EF), with academic and adaptive skills among youth with PHIV and perinatally HIV-exposed but uninfected (PHEU) youth.
Methods: Participants ages 9 to <19 years enrolled in the Pediatric HIV/AIDS Cohort Study's Memory and Executive Functioning Study completed standardized measures of reading and math.
Background: Executive functions (EFs) are critical for management of life activities, but few studies have evaluated EFs in children and adolescents with perinatally acquired HIV (PHIV), who are at risk for problems in academics, behavior, and medication adherence. We compared EFs in youth with PHIV and in perinatally HIV-exposed but uninfected (PHEU) youth.
Methods: Four Delis-Kaplan Executive Function System (D-KEFS) subtests were administered to 173 youth with PHIV and 85 PHEU youth, aged 9 to <19 years, who were enrolled in the Pediatric HIV/AIDS Cohort Study (PHACS) Memory and Executive Functioning Study.
Background: Sexually transmitted infections (STIs), including human immunodeficiency virus (HIV), disproportionately affect adolescents and young adults (AYAs) ages 13-24 years. Sexually transmitted infections likewise are a risk factor for HIV acquisition and transmission; however, there is a lack of data on STI acquisition in HIV-infected AYAs.
Methods: We determined the incidence of STIs in HIV-infected AYAs 12.
Background: Learning and memory in youth with perinatally acquired HIV (PHIV) are poorly understood, despite their importance for academic, healthcare and daily functioning.
Methods: PHIV (n = 173) and perinatally HIV-exposed but uninfected (PHEU, n = 85) participants (aged 9-19 years) in a substudy of the Pediatric HIV/AIDS Cohort Study completed age-standardized tests of verbal and visual learning and delayed memory. Linear regression models implemented via generalized estimating equations were used to compare memory measures in PHEU participants versus PHIV youth with and without Centers for Disease Control and Prevention class C diagnosis (PHIV-C, n = 45 and PHIV-non-C, n = 128, respectively), adjusting for sociodemographic covariates.
Background: Perinatal HIV (PHIV) infection may place youth at risk for impairments in executive functioning (EF). We examined associations of EF with HIV infection, disease severity and other factors among youth with PHIV and perinatally HIV-exposed, uninfected youth (PHEU).
Methods: Within the US-based Pediatric HIV/AIDS Cohort Study, 354 PHIV and 200 PHEU youth completed a standardized EF measure (Children's Color Trails Test, CCTT) and youth and/or caregivers completed a questionnaire measuring everyday EF (Behavior Rating Inventory of Executive Function, BRIEF).
Background: Among human immunodeficiency virus (HIV)-infected youth, the role of renal disease (RD) and its management has become increasingly important as these children/adolescents mature into young adults. The identification of predictors of abnormal renal laboratory events (RLE) may be helpful in the management of their HIV infection and its associated renal complications.
Methods: Data collected from HIV-infected youth followed for ≥ 48 months were analyzed to identify predictors of resolution versus persistence of RLE and determine the utility of RLE to predict the onset of RD.
Little is known about the relationship between traumatic head injury (THI) and psychiatric morbidity in torture survivors. We examine the relationship between THI and depression, PTSD, post-concussive syndrome (PCS), disability and poor health status in Vietnamese ex-political detainees who survived incarceration in Vietnamese re-education camps. A community sample of ex-political detainees (n=337) and a non-THI, non-ex-detainee comparison group (n=82) were surveyed.

Methods: History, urine and blood were collected at regular intervals from 448 children and adolescents with perinatal HIV-1 infection followed in the Pediatric HIV/AIDS Cohort study.
Background: This study describes the incidence, clinical and demographic characteristics, and spectrum of chronic kidney disease (CKD) in youths with perinatal HIV-1 infection.
Methods: Retrospective analysis between May 1993 and December 2006 of subjects with renal disease followed in the Pediatric AIDS Clinical Trials Group 219/219C multicenter study examining the long-term consequences of perinatal HIV infection. Diagnosis confirmation was made utilizing a questionnaire mailed to research sites.

Background: Advances in therapy have allowed children with perinatal HIV infection in the United States to survive into adolescence. We sought to describe the disease status of a large cohort of such children and identify predictors of their current CD4 count and HIV viral load (VL).
Methods: The Pediatric HIV/AIDS Cohort Study AMP Protocol is an ongoing prospective study conducted at 15 sites in the United States.
Background: Mitochondrial dysfunction has been associated with both human immunodeficiency virus (HIV) infection and exposure to antiretroviral therapy. Mitochondrial dysfunction has not been widely studied in HIV-infected children. We estimated the incidence of clinically defined mitochondrial dysfunction among children with perinatal HIV infection.
View Article and Find Full Text PDFContext: A pilot study of South Vietnamese ex-political detainees who had been incarcerated in Vietnamese reeducation camps and resettled in the United States disclosed significant mental health problems associated with torture and traumatic head injury (THI).
Objectives: To identify structural brain alterations associated with THI and to investigate whether these deficits are associated with posttraumatic stress disorder and depression.
Design: Cross-sectional neuroimaging study.
Background: Survival of HIV-infected children continues to increase and the use of antiretrovirals (ARVs) is expanding; however there are few data regarding the incidence of renal dysfunction and associated risk factors among HIV-infected children and youth.
Methods: A total of 2102 children enrolled in Pediatric AIDS Clinical Trials Group Study 219/219C, were followed and assessed prospectively for >30 months. Occurrence of clinical events and laboratory abnormalities were recorded using standardized criteria and forms.
Context: Combination anti-retroviral therapy or highly active antiretroviral therapy (HAART) has resulted in a dramatic decline in the incidence of opportunistic and other infections in human immunodeficiency virus (HIV)-infected adults and children.
Objectives: To estimate the incidence of 29 targeted opportunistic and other infections occurring in the era of HAART-between January 1, 2001, and December 31, 2004-in HIV-infected infants, children, and adolescents followed up in Pediatric AIDS Clinical Trials Group (PACTG) 219C; to compare incidence rates in the HAART era to those of the pre-HAART era; and to test for linear trends over time in the HAART era.
Design, Setting, And Participants: Ongoing, multicenter, prospective cohort study designed to examine long-term outcomes in HIV-infected children.
