RESUMEN

BACKGROUND: Long-acting injectable cabotegravir and rilpivirine have demonstrated safety, acceptability, and efficacy in adults living with HIV-1. The IMPAACT 2017 study (MOCHA study) was the first to use these injectable formulations in adolescents (aged 12-17 years) living with HIV-1. Herein, we report acceptability and tolerability outcomes in cohort 1 of the study. METHODS: In this a secondary analysis of a phase 1/2, multicentre, open-label, non-comparative dose-finding study, with continuation of pre-study oral combination antiretroviral treatment (ART), 55 adolescents living with HIV-1 were enrolled to receive sequential doses of either long-acting cabotegravir or rilpivirine and 52 received at least two injections. Participants had a body weight greater than 35 kg and BMI less than 31·5 kg/m2 and had been on stable ART for at least 90 consecutive days with an HIV-1 viral load of less than 50 copies per mL at a participating IMPAACT study site. Participants had to be willing to continue their pre-study ART during cohort 1. The primary objectives of the study were to confirm doses for oral and injectable cabotegravir and for injectable rilpivirine in adolescents living with HIV. This analysis of participant-reported outcomes included a face scale assessment of pain at each injection and a Pediatric Quality of Life Inventory (PedsQL) at baseline and week 16 for participants in the USA, South Africa, Botswana, and Thailand. A subset of 11 adolescents and 11 parents or caregivers in the USA underwent in-depth interviews after receipt of one or two injections. This trial is registered at ClinicalTrials.gov, NCT03497676. FINDINGS: Between March 19, 2019, and Nov 25, 2021, 55 participants were enrolled into cohort 1. Using the six-point face scale, 43 (83%) of participants at week 4 and 38 (73%) at week 8 reported that the injection caused "no hurt" or "hurts little bit", while only a single (2%) participant for each week rated the pain as one of the two highest pain levels. Quality of life was not diminished by the addition of one injectable antiretroviral. In-depth interviews revealed that parents and caregivers in the USA frequently had more hesitancy than adolescents about use of long-acting formulations, but parental acceptance was higher after their children received injections. INTERPRETATION: High acceptability and tolerability of long-acting cabotegravir or rilpivirine injections suggests that these are likely to be favoured treatment options for some adolescents living with HIV.

RESUMEN

BACKGROUND: Combined intramuscular long-acting cabotegravir and long-acting rilpivirine constitute the first long-acting combination antiretroviral therapy (ART) regimen approved for adults with HIV. The goal of the IMPAACT 2017 study (MOCHA [More Options for Children and Adolescents]) was to assess the safety and pharmacokinetics of these drugs in adolescents. METHODS: In this phase 1/2, multicentre, open-label, non-comparative, dose-finding study, virologically suppressed adolescents (aged 12-17 years; weight ≥35 kg; BMI ≤31·5 kg/m2) with HIV-1 on daily oral ART were enrolled at 15 centres in four countries (Botswana, South Africa, Thailand, and the USA). After 4-6 weeks of oral cabotegravir (cohort 1C) or rilpivirine (cohort 1R), participants received intramuscular long-acting cabotegravir or long-acting rilpivirine every 4 weeks or 8 weeks per the adult dosing regimens, while continuing pre-study ART. The primary outcomes were assessments of safety measures, including all adverse events, until week 4 for oral cabotegravir and until week 16 for long-acting cabotegravir and long-acting rilpivirine, and pharmacokinetic measures, including the area under the plasma concentration versus time curve during the dosing interval (AUC0-tau) and drug concentrations, at week 2 for oral dosing of cabotegravir and at week 16 for intramuscular dosing of cabotegravir and rilpivirine. Enrolment into cohort 1C or cohort 1R was based on the participant's pre-study ART, meaning that masking was not done. For pharmacokinetic analyses, blood samples were drawn at weeks 2-4 after oral dosing and weeks 4-16 after intramuscular dosing. Safety outcome measures were summarised using frequencies, percentages, and exact 95% CIs; pharmacokinetic parameters were summarised using descriptive statistics. This trial is registered at ClinicalTrials.gov, NCT03497676, and is closed to enrolment. FINDINGS: Between March 19, 2019, and Nov 25, 2021, 55 participants were enrolled: 30 in cohort 1C and 25 in cohort 1R. At week 16, 28 (97%, 95% CI 82-100) of the 29 dose-evaluable participants in cohort 1C and 21 (91%; 72-99) of the 23 dose-evaluable participants in cohort 1R had reported at least one adverse event, with the most common being injection-site pain (nine [31%] in cohort 1C; nine [39%] in cohort 1R; none were severe). One (4%, 95% CI 0-22) participant in cohort 1R had an adverse event of grade 3 or higher, leading to treatment discontinuation, which was defined as acute rilpivirine-related allergic reaction (self-limiting generalised urticaria) after the first oral dose. No deaths or life-threatening events occurred. In cohort 1C, the week 2 median cabotegravir AUC0-tau was 148·5 (range 37·2-433·1) µg·h/mL. The week 16 median concentrations for the every-4-weeks and every-8-weeks dosing was 3·11 µg/mL (range 1·22-6·19) and 1·15 µg/mL (<0·025-5·29) for cabotegravir and 52·9 ng/mL (31·9-148·0) and 39·1 ng/mL (27·2-81·3) for rilpivirine, respectively. These concentrations were similar to those in adults. INTERPRETATION: Study data support using long-acting cabotegravir or long-acting rilpivirine, given every 4 weeks or 8 weeks, per the adult dosing regimens, in virologically suppressed adolescents aged 12 years and older and weighing at least 35 kg.

RESUMEN

Since the rotavirus vaccine was included in the Dominican Republic's national immunization schedule in 2012, the microbiologic etiologies of acute gastroenteritis have not been described. This study aimed to determine the contribution of rotavirus as an etiology of acute gastroenteritis over a 12-month period in children under 5 years of age in both an inpatient and an outpatient setting in Consuelo, Dominican Republic. All children who were seen at Niños Primeros en Salud clinic or admitted to Hospital Municipal Dr. Angel Ponce Pinedo for acute gastroenteritis during January 2021-April 2022 were enrolled in the study. Stools were evaluated for rotavirus, enteric parasites, and pathogenic bacteria. Pathogen detection was compared between outpatients and inpatients and on the basis of child's vaccination status. From 181 children enrolled, 170 stool samples were collected, 28 (16.5%) from inpatients and 142 (83.5%) from outpatients. Rotavirus was the most commonly detected pathogen and was proportionately more common among hospitalized children, with nine (32.1%) cases among hospitalized children and 16 (11.3%) among outpatient children. (Pearson χ2 = 8.1, P = 0.004). Among patients with a positive rotavirus result, vaccination rate was lower among moderate (hospitalized) (three of six; 50%) compared with mild (outpatient) diarrhea patients (12 of 15; 80%). Giardia lamblia (10%) was the next most prevalent pathogen detected in both inpatients and outpatients using standard laboratory measures. Despite the availability of rotavirus vaccination, rotavirus remains a common cause of gastrointestinal illness among children under 5 years of age in our cohort. Incomplete vaccination status was associated with hospitalization for gastrointestinal illness.

RESUMEN

Despite widespread availability of life-saving antiretroviral therapy (ART) in sub-Saharan Africa, AIDS remains one of the leading causes of death among adolescents living with HIV (ALHIV) in sub-Saharan Africa. The purpose of this article was to review the state of the science regarding interventions to improve ART adherence and/or HIV care retention among ALHIV throughout sub-Saharan Africa. The primary aim of this review was to describe the impact of peer support interventions in improving treatment outcomes (i.e., ART adherence and retention in HIV care) among ALHIV in sub-Saharan Africa. The secondary aim of this review was to determine whether these interventions may be efficacious at improving mental health outcomes. We identified 27 articles that met the eligibility criteria for our review, and categorized each article based on the type of peer support provided to ALHIV-individualized peer support, group-based support, and individualized plus group-based support. Results regarding the efficacy of these interventions are mixed and most of the studies included were deemed moderate in methodological quality. Although studies evaluating group-based peer support interventions were the most common, most of these studies were not associated with retention, adherence, or mental health outcomes. More robust, fully powered studies are needed to strengthen our knowledge base regarding peer support for ALHIV.

RESUMEN

There is wide variation in how individuals perceive the chemosensory attributes of liquid formulations of ibuprofen, encompassing both adults and children. To understand personal variation in the taste and chemesthesis properties of this medicine, and how to measure it, our first scientific strategy centered on utilizing trained adult panelists, due to the complex and time-consuming psychophysical tasks needed at this initial stage. We conducted a double-blind cohort study in which panelists underwent whole-genome-wide genotyping and psychophysically evaluated an over-the-counter pediatric medicine containing ibuprofen. Associations between sensory phenotypes and genetic variation near/within irritant and taste receptor genes were determined. Panelists who experienced the urge to cough or throat sensations found the medicine less palatable and sweet, and more irritating. Perceptions varied with genetic ancestry; panelists of African genetic ancestry had fewer chemesthetic sensations, rating the medicine sweeter, less irritating, and more palatable than did those of European genetic ancestry. We discovered a novel association between TRPA1 rs11988795 and tingling sensations, independent of ancestry. We also determined for the first time that just tasting the medicine allowed predictions of perceptions after swallowing, simplifying future psychophysical studies on diverse populations of different age groups needed to understand genetic, cultural-dietary, and epigenetic factors that influence individual perceptions of palatability and, in turn, adherence and the risk of accidental ingestion.

RESUMEN

Youth living with HIV (YLWH) have higher rates of common mental disorders (CMDs) when compared with HIV-negative youth. We adapted the Friendship Bench to create a problem solving-based counselling intervention in Botswana delivered by near peer youth lay counsellors for YLWH called Safe Haven. In August 2020, and from June to August 2021, we conducted 22 semistructured interviews with youth aged 13-25 years with mild-to-moderate symptoms of CMDs. Two independent coders carried out an inductive thematic analysis of the transcribed interviews with discrepancies discussed to consensus. Safe Haven was seen as largely acceptable among the youth. Youth felt Safe Haven was a place where they had freedom of expression and could receive practical advice from well-trained and approachable counsellors. Trained youth lay peer counsellors show promise to meet the mental health needs of mild and moderately symptomatic youth, where mental health professionals are in short supply.

RESUMEN

BACKGROUND: The healthcare transition (HCT) from pediatric to adult HIV care can be disruptive to HIV care engagement and viral suppression for youth living with HIV (YLH). METHODS: We performed qualitative interviews with 20 YLH who experienced HCT and with 20 multidisciplinary pediatric and adult HIV clinicians to assess and rank barriers and facilitators to HCT and obtain their perspectives on strategies to improve the HCT process. We used the Exploration Preparation Implementation Sustainment Framework to guide this qualitative inquiry. RESULTS: The most impactful barriers identified by YLH and clinicians focused on issues affecting the patient-clinician relationship, including building trust, and accessibility of clinicians. Both groups reported that having to leave the pediatric team was a significant barrier (ranked #1 for clinicians and #2 for YLH). The most impactful facilitator included having a social worker or case manager to navigate the HCT (listed #1 by clinicians and #2 by YLH); case managers were also identified as the individual most suited to support HCT. While YLH reported difficulty building trust with their new clinician as their #1 barrier, they also ranked the trust they ultimately built with a new clinician as their #1 facilitator. Factors reported to bridge pediatric and adult care included providing a warm handoff, medical record transfer, developing relationships between pediatric clinics and a network of youth-friendly adult clinics, and having the pediatric case manager attend the first adult appointment. Longer new patient visits, increased health communication between YLH and clinicians and sharing vetted clinician profiles with YLH were identified as innovative strategies. CONCLUSION: In this multi-disciplinary contextual inquiry, we have identified several determinants that may be targeted to improve HCT for YLH.

RESUMEN

BACKGROUND: HIV increases the risk of atherosclerosis and cardiovascular diseases (CVD). This risk maybe even higher in adult survivors of perinatal HIV infection because of prolonged exposure to HIV and its treatments. Nutritional deprivation in early life may further increase CVD risk. SETTING: Botswana-Baylor Children's Clinical Centre of Excellence, Gaborone. METHODS: This study examined dyslipidemia in 18- to 24-year olds with perinatally-acquired HIV with and without linear growth retardation ("stunting"). Anthropometry and lipid profiles were measured following a minimum 8-hour fast. Stunting was defined by a height-for-age z-score of <2 SDs below the mean. Dyslipidemia was defined by non-high-density lipoprotein cholesterol (HDL-C) of ≥130 mg/dL, low-density lipoprotein cholesterol (LDL-C) of ≥100 mg/dL, or HDL of <40 mg/dL for male subjects and <50 mg/dL for female subjects. We used logistic regression to determine whether dyslipidemia was associated with stunting while adjusting for demographic and HIV treatment variables. RESULTS: Of 107 young adults (46 males; 61 females) enrolled, 36 (33.6%) were stunted. Prevalence of dyslipidemia was 11.2%, 24.3%, and 65.4% for high non-HDL-C, high LDL-C, and low HDL-C, respectively. In univariable analysis, being stunted was associated with elevated LDL-C (odds ratio [OR], 2.52; 95% confidence interval [CI] =1.02 to 6.25) but not with elevated non-HDL-C (OR = 2.17; 95% CI: = 0.65 to 7.28) or with low HDL-C (OR = 0.75; 95% CI: = 0.33 to 1.73). The association between stunting and elevated LDL-C (OR = 4.40; 95% CI: = 1.49 to 12.98) remained significant after controlling for measured confounders. CONCLUSION: Dyslipidemia was common among perinatally HIV-infected youth and those with evidence of early nutritional deprivation who were more likely to have elevated LDL-C.

RESUMEN

Globally, mental health problems have been reported to be more common in youth living with HIV (YLWH) than in the general population, but routine mental health screening is rarely done in high-volume HIV clinics. In 2019, YLWH in a large HIV clinic in Botswana were screened using the Generalized Anxiety Scale-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9) in a pilot standard-of-care screening programme. Two-way ANOVA was used to describe the effects of age group (12-<16, 16-<20 and 20-25 years old) and sex on GAD-7 and PHQ-9 scores. Chi-square statistics were used to compare characteristics of YLWH with and without potential suicidality/self-harm symptoms based on question 9 in the PHQ-9. Among 1 469 YLWH, 33.1%, 44.3% and 15.0% had anxiety, depression and potential suicidality/self-harm symptoms respectively. YLWH of 20-25 years old and 16-<20 years old had higher GAD-7 scores compared to 12-<16-year-olds (p = 0.014 and p = <0.001 respectively). Female YLWH of 20-25 years old had higher PHQ-9 scores compared to 12-<16-year-olds (p = 0.002). There were no other sex-age dynamics that were statistically significant. Female YLWH endorsed more thoughts of suicidality/self-harm than males (17% versus 13%, p = 0.03 respectively). Given the proportion of YLWH with mental health symptoms, Botswana should enhance investments in mental health services for YLWH, especially for young female adults who bear a disproportionate burden.

RESUMEN

Human immunodeficiency virus (HIV) infection is prevalent among children and adolescents in Botswana, but standardized neurocognitive testing is limited. The Penn Computerized Neurocognitive Battery (PennCNB) attempts to streamline evaluation of neurocognitive functioning and has been culturally adapted for use among youth in this high-burden, low-resource setting. However, its reliability across measurements (i.e., test-retest reliability) is unknown. This study examined the test-retest reliability of the culturally adapted PennCNB in 65 school-age children (age 7-17) living with HIV in Botswana. Intraclass correlation coefficients (ICCs) for PennCNB summary scores (ICCs > 0.80) and domain scores (ICCs = 0.66-0.88) were higher than those for individual tests, which exhibited more variability (ICCs = 0.50-0.82), with the lowest reliability on memory tests. Practice effects were apparent on some measures, especially within memory and complex cognition domains. Taken together, the adapted PennCNB exhibited adequate test-retest reliability at the domain level but variable reliability for individual tests. Differences in reliability should be considered in implementation of these tests.

RESUMEN

We investigated perceived impacts of COVID-19 on the delivery of adolescent HIV treatment and prevention services in sub-Saharan Africa (SSA) by administering a survey to members of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA) from February to April 2021. We organized COVID-19 impacts, as perceived by AHISA teams, under three themes: service interruptions, service adjustments, and perceived individual-level health impacts. AHISA teams commonly reported interruptions to prevention programs, diagnostic testing, and access to antiretroviral therapy (ART). Common service adjustments included decentralization of ART refills, expanded multi-month ART distribution, and digital technology use. Perceived individual-level impacts included social isolation, loss to follow-up, food insecurity, poverty, and increases in adolescent pregnancies and sexually transmitted infections. The need for collaboration among stakeholders were commonly cited as lessons learned by AHISA teams. Survey findings highlight the need for implementation science research to evaluate the effects of pandemic-related HIV service adaptations in SSA.

RESUMEN

Members of the Adolescent HIV Prevention and Treatment Implementation Science Alliance (AHISA) network conduct research aiming to close gaps between what is known to be impactful across the HIV prevention and treatment cascade, and services delivered to optimize outcomes for adolescents/young adults (AYA) in high HIV-prevalence settings. The COVID-19 pandemic introduced new challenges which threaten to exacerbate care and access disparities. We report results of a survey among AHISA teams with active AYA HIV research programs in African countries to determine how the pandemic has impacted their efforts. Results highlighted the detrimental impact of the pandemic on research efforts and the expanded need for implementation research to help provide evidence-based, context-specific pandemic recovery support. Key lessons learned included the viability of remote service delivery strategies and other innovations, the need for adaptive systems that respond to evolving contextual needs, and the need for organized documentation plans, within empathic and flexible environments.

RESUMEN

Children living with HIV (HIV+) experience increased risk of neurocognitive deficits, but standardized cognitive testing is limited in low-resource, high-prevalence settings. The Penn Computerized Neurocognitive Battery (PennCNB) was adapted for use in Botswana. This study evaluated the criterion validity of a locally adapted version of the PennCNB among a cohort of HIV+ individuals aged 10-17 years in Botswana. Participants completed the PennCNB and a comprehensive professional consensus assessment consisting of pencil-and-paper psychological assessments, clinical interview, and review of academic performance. Seventy-two participants were classified as cases (i.e., with cognitive impairment; N = 48) or controls (i.e., without cognitive impairment; N = 24). Sensitivity, specificity, positive predictive value, negative predictive value, and the area under receiver operating characteristic curves were calculated. Discrimination was acceptable, and prediction improved as the threshold for PennCNB impairment was less conservative. This research contributes to the validation of the PennCNB for use among children affected by HIV in Botswana.

RESUMEN

HIV infection and in utero exposure, common in Sub-Saharan Africa, are associated with pediatric neurocognitive impairment. Cognitive screening can identify impairments, but it is rarely used in this setting. The Penn Computerized Neurocognitive Battery (PennCNB), an evidence-based cognitive screening tool, was adapted for use in Botswana. To facilitate future implementation, 20 semi-structured interviews were conducted to elicit key stakeholders' perspectives on factors likely to be related to successful uptake of the PennCNB in clinical settings. An integrated analytic approach combining constructs from the Consolidated Framework for Implementation Research and modified grounded theory was used. Results underscore the need for cognitive screening in Botswana and the acceptability of the PennCNB. Implementation barriers include limited time and resources, whereas facilitators include standard procedures for introducing new tools into medical settings and for training implementers. Recommended implementation strategies include integrating screening into the existing workflow, implementing the tool in the medical and educational sectors, and targeting selection of children for assessment. This research addresses the research-to-practice gap by engaging in pre-implementation inquiry and designing for implementation. Results will inform the development of strategies to maximize the likelihood of successful implementation of the PennCNB to identify neurocognitive impairment in children in this high-need setting.

RESUMEN

Adolescents with suboptimal medication taking may deceive caregivers about non-adherence. We conducted a 5-year longitudinal study of adolescents monitored simultaneously with both easily manipulated (e.g., self-report) and hard to manipulate (e.g., microelectronic data) strategies. Adolescents with repeatedly high adherence on the former and low adherence on the latter were invited along with their parental figures ("parents") to participate. We conducted focus groups and semi-structured interviews, separately for adolescents and parents, to elucidate drivers of discordant measures. Forty-seven adolescents and 26 parents participated in focus groups and 4 adolescents were interviewed. Adolescents described hiding pills, discarding pills, and lying. Their motivations included fear of disappointing those who care about them, desire to avoid admonishment by parents and clinic staff, and desire to avoid remedial adherence counseling. Both adolescents and parents considered negative feedback for prior poor adherence to be key motivation to hide current poor adherence from clinic staff. Providing positive feedback for truth-telling, rather than for "evidence" of excellent adherence, might help adolescent patients and their parents to develop stronger treatment alliances with each other and with clinic staff. Such alliances would allow adherence interventions to be better targeted and more fruitful in increasing adherence.

RESUMEN

BACKGROUND: Iron deficiency anemia affects millions of children worldwide. Iron intake assessments can inform targeted interventions. METHODS: This cross-sectional study describes diet and hemoglobin levels of children 1-5 y of age in a resource-limited setting in the Dominican Republic. The study team performed meal observations and measurements, dietary questionnaires, and point-of-care hemoglobin testing. RESULTS: Iron intake and bioavailability were low, with liberal estimates indicating that not more than 40% of subjects consumed the recommended daily allowance for iron. Forty of 80 children had anemia, with 23% demonstrating moderate or severe anemia. CONCLUSIONS: Poor observed iron intake likely contributes to the high prevalence of anemia in this population.

RESUMEN

Children born to mothers infected with the human immunodeficiency virus (HIV) during pregnancy experience increased risk of neurocognitive impairment. In Botswana, HIV infection is common among youth, but standardized cognitive screening is limited. The Penn Computerized Neurocognitive Battery (PennCNB), a tool that streamlines evaluation of neurocognitive functioning, was culturally adapted for use among youth in this high-burden, low-resource setting. The present study examined the structural validity of the culturally adapted PennCNB. A cohort of 7-17-year-old children living with HIV (HIV +) and HIV-exposed-uninfected (HEU) children were enrolled from the Botswana-Baylor Children's Clinical Centre of Excellence in Gaborone, Botswana. Confirmatory and exploratory factor analyses were performed on speed, accuracy, and efficiency measures for 13 PennCNB tests. Fit of the confirmatory factor analysis was acceptable, which supports the design of the battery measuring four neurocognitive domains: Executive functioning, episodic memory, complex cognition, and sensorimotor/processing speed. However, the model revealed high interfactor correlation. Exploratory factor analysis suggested that tests assessing executive functioning and sensorimotor/processing speed clustered together rather than forming differentiable factors. Overall, this research provides valuable insight into the structural validity of a neurocognitive battery adapted for use in a non-Western setting, suggesting that the PennCNB could serve as a useful tool for the assessment of neurocognitive function in Botswana and, potentially, other resource-limited settings.

RESUMEN

Background. The World Health Organization recommends biannual deworming with single-dose albendazole for all children over 1 year in regions where soil-transmitted helminths (STH) are endemic. There are limited data from the Dominican Republic (DR) on the effectiveness of deworming programs. Methods. Between January and June 2019, we enrolled 63 preschool-aged children at a community clinic in the DR. Participants received albendazole at enrollment. Stool samples were collected and examined for parasites at enrollment, 2 to 4 and 12 to 16 weeks post-albendazole. Caregivers were surveyed on home hygiene practices and children's symptoms. Findings. At enrollment, 1 or more parasites were noted in 89% of samples. Ascaris lumbricoides (68%) was the most common species, followed by Entamoeba histolytica (35%) and Giardia intestinalis (8%). Two-to-four weeks post-albendazole, fewer than half of those with A. lumbricoides infections at baseline had cleared the infection. STH symptoms significantly improved between enrollment and 2 to 4 weeks. By 12 to 16 weeks after treatment, A. lumbricoides infections were as high as baseline. Interpretation. Although limited by size and available technology, our study contributes data on STH in the DR. Single-dose deworming with albendazole did not reduce Ascaris lumbricoides infections in our sample. As STH are the most common neglected tropical diseases and negatively impact children's health globally, further studies on both effective deworming programs and interventions to prevent STH are needed.

RESUMEN

A safe and healthy natural and built environment is fundamental to children's health and represents a significant determinant of community well-being. We aimed to identify and prioritize environmental health concerns within resource-poor neighborhoods in the Dominican Republic using free-listing and semi-structured focus groups composed of parents and caregivers in the perirural community of Consuelo, Dominican Republic. Transcripts were coded and relevant themes identified using qualitative content analysis. Demographic data and information regarding trash disposal practices were also collected. Participants described common health concerns, including respiratory infections, asthma, vector-borne illnesses, and diarrheal diseases and linked them to environmental hazards in their communities, such as air quality and sanitation. Interventional priorities that emerged included reduction of trash accumulation and trash burning as well as improvement of sanitation facilities.

RESUMEN

Many children and adolescents around the world suffer from neurocognitive deficits due to chronic disorders, such as Human Immunodeficiency Virus (HIV) and malaria. Resource-limited settings exacerbate the risk of negative cognitive outcomes due to high prevalence of associated disorders, poverty, and limited access to interventions. Current literature does not provide consensus regarding the efficacy of interventions to support children with cognitive impairments in low-resource settings. This research aimed to identify and evaluate interventions for youth with neurocognitive deficits in resource-limited settings. A systematic review of peer-reviewed literature was conducted within five databases (PubMed, Web of Science, CINAHL, PsycInfo, and WHO Index Medicus). Cognitive impairment was broadly defined to be inclusive of aspects of intellectual and cognitive functioning (e.g., working memory, attention, executive function). The income status of the country or countries in which each study was located was determined according to World Bank Income Status. Studies conducted in countries classified as low- or middle-income were included. Since low-resource areas exist within high-income countries, the resource availability within study settings in high-income countries was systematically evaluated for inclusion. The search yielded 19 articles that met all inclusion criteria. Interventions included strategies involving caregiver training, computerized and non-computerized cognitive training, physical activity, and nutritional supplementation. Interventions were administered in medical facilities, educational facilities, or the home. The majority of the interventions targeted the domains of memory and attention. Overall, the efficacy of interventions was inconsistent. Further, results indicated that the relationship between cognitive improvement and intervention types was not consistent across cognitive domains. However, when evaluating studies on an individual basis, some strategies demonstrated clinically- and statistically-significant improvement in cognitive function among specific groups of children. The low article yield highlights that few researchers have evaluated pediatric cognitive support interventions in low-resource contexts. This review suggests support strategies that should be considered for future studies as neurocognitive screening capacity improves in resource-limited settings.
