Background: Population-based data show high proportions of severe cases of cerebral palsy (CP) in resource-poor regions such as sub-Saharan Africa, where most children have potentially preventable risk factors (factors that may increase the likelihood of CP occurrence but can be mitigated through medical interventions).Objectives: This study aimed to describe the demographic and clinical profile of children living with CP accessing services at Tygerberg Hospital over a period of 10 years (2010–2020), identify the potential gaps in care (proportion of individuals in a country requiring but not receiving suboptimal or inadequate care), and comparison with a similar study at the same centre two decades ago.Method: This 10-year retrospective study investigated causes and morbidities in children with CP, attending a central hospital in the Western Cape, South Africa.Results: A total of 613 children with CP were identified. Perinatal causes were predominant, especially in 57.7% (n = 354) of the cohort: perinatal asphyxia (41.1%) and preterm birth (16.6%). Postnatal causes constituted 15.2% (n = 93), which included tuberculous meningitis (3.6%) and bacterial meningitis (3.6%). The most common complications were intellectual impairment (61.8%; n = 379); epilepsy (30.8%; n = 189) and visual impairment (54.7%; n = 234). A third of the cohort had severe CP, classified as Gross Motor Function Classification System IV and V (38%).Conclusion: Most of the previously documented main drivers of CP are still present and the implementation of healthcare prevention strategies remains inadequate.Contribution: This study provides longitudinal evidence to confirm that CP in a South African setting is associated with a high burden of potentially preventable causes.

The last fifteen years have witnessed a significant increase in investment in research ethics capacity development throughout the world. We examine nine research ethics training programs that are focused on Sub-Saharan Africa and supported by the US National Institutes of Health. We collected data from grants awards' documents and annual reports supplemented by questionnaires completed by the training program directors. Together, these programs provided long-term training in research ethics to 275 African professionals, strengthened research ethics committees in 19 countries in Sub-Saharan Africa, and created research ethics curricula at many institutions and bioethics centers within Africa. Trainees' leadership resulted in new national systems and policies on research ethics, human tissue storage and export, and methods of monitoring compliance with research ethics guidelines. Training programs adapted to challenges that arose due to varied trainees' background knowledge in ethics, duration of time available for training, spoken and written English language skills, administrative obstacles, and the need to sustain post-training research ethics activities. Our report showcases the development of awareness of research ethics and building/strengthening of basic research ethics infrastructure in Sub-Saharan Africa. Nevertheless, the increasing amount and complexity of health research being conducted in Sub-Saharan Africa suggests the need for continued investment in research ethics capacity development in this region. This paper is part of a collection of papers analyzing the Fogarty International Center's International Research Ethics Education and Curriculum Development program.

AbstractIntroductionEarly antiretroviral therapy (ART) has improved neurodevelopmental outcomes of HIV‐infected (HIV‐positive) children; however, little is known about the longer term outcomes in infants commencing early ART or whether temporary ART interruption might have long‐term consequences. In the children with HIV early antiretroviral treatment (CHER) trial, HIV‐infected infants ≤12 weeks of age with CD4 ≥25% were randomized to deferred ART (ART‐Def); immediate time‐limited ART for 40 weeks (ART‐40W) or 96 weeks (ART‐96W). ART was restarted in the time‐limited arms for immunologic/clinical progression. Our objective was to compare the neurodevelopmental profiles in all three arms of Cape Town CHER participants.MethodsA prospective, longitudinal observational study was used. The Griffiths mental development scales (GMDS), which includes six subscales and a global score, were performed at 11, 20, 30, 42 and 60 months, and the Beery‐Buktenica developmental tests for visual motor integration at 60 months. HIV‐exposed uninfected (HEU) and HIV‐unexposed (HU) children were enrolled for comparison. Mixed model repeated measures were used to compare groups over time, using quotients derived from standardized British norms.ResultsIn this study, 28 ART‐Def, 35 ART‐40W, 33 ART‐96W CHER children, and 34 HEU and 39 HU controls were enrolled. GMDS scores over five years were similar between the five groups in all subscales except locomotor and general Griffiths (interaction p < 0.001 and p = 0.02 respectively), driven by early lower scores in the ART‐Def arm. At 60 months, scores for all groups were similar in each GMDS scale. However, Beery visual perception scores were significantly lower in HIV‐infected children (mean standard scores: 75.8 ART‐Def, 79.8 ART‐40W, 75.9 ART‐96W) versus 84.4 in HEU and 90.5 in HU (p < 0.01)).ConclusionsEarly locomotor delay in the ART‐Def arm resolved by five years. Neurodevelopmental outcomes at five years in HIV‐infected children on early time‐limited ART were similar to uninfected controls, apart from visual perception where HIV‐infected children scored lower. Poorer visual perception performance warrants further investigation.

Importance: Little is known about COVID-19 outcomes among children and adolescents in sub-Saharan Africa, where preexisting comorbidities are prevalent. Objective: To assess the clinical outcomes and factors associated with outcomes among children and adolescents hospitalized with COVID-19 in 6 countries in sub-Saharan Africa. Design, Setting, and Participants: This cohort study was a retrospective record review of data from 25 hospitals in the Democratic Republic of the Congo, Ghana, Kenya, Nigeria, South Africa, and Uganda from March 1 to December 31, 2020, and included 469 hospitalized patients aged 0 to 19 years with SARS-CoV-2 infection. Exposures: Age, sex, preexisting comorbidities, and region of residence. Main Outcomes and Measures: An ordinal primary outcome scale was used comprising 5 categories: (1) hospitalization without oxygen supplementation, (2) hospitalization with oxygen supplementation, (3) ICU admission, (4) invasive mechanical ventilation, and (5) death. The secondary outcome was length of hospital stay. Results: Among 469 hospitalized children and adolescents, the median age was 5.9 years (IQR, 1.6-11.1 years); 245 patients (52.4%) were male, and 115 (24.5%) had comorbidities. A total of 39 patients (8.3%) were from central Africa, 172 (36.7%) from eastern Africa, 208 (44.3%) from southern Africa, and 50 (10.7%) from western Africa. Eighteen patients had suspected (n = 6) or confirmed (n = 12) multisystem inflammatory syndrome in children. Thirty-nine patients (8.3%) died, including 22 of 69 patients (31.9%) who required intensive care unit admission and 4 of 18 patients (22.2%) with suspected or confirmed multisystem inflammatory syndrome in children. Among 468 patients, 418 (89.3%) were discharged, and 16 (3.4%) remained hospitalized. The likelihood of outcomes with higher vs lower severity among children younger than 1 year expressed as adjusted odds ratio (aOR) was 4.89 (95% CI, 1.44-16.61) times higher than that of adolescents aged 15 to 19 years. The presence of hypertension (aOR, ...
