Task shifting roles, interventions and outcomes for kidney and cardiovascular health service delivery among African populations: a scoping review.

BACKGROUND: Human resources for health (HRH) shortages are a major limitation to equitable access to healthcare. African countries have the most severe shortage of HRH in the world despite rising communicable and non-communicable disease (NCD) burden. Task shifting provides an opportunity to fill the gaps in HRH shortage in Africa. The aim of this scoping review is to evaluate task shifting roles, interventions and outcomes for addressing kidney and cardiovascular (CV) health problems in African populations. METHODS: We conducted this scoping review to answer the question: "what are the roles, interventions and outcomes of task shifting strategies for CV and kidney health in Africa?" Eligible studies were selected after searching MEDLINE (Ovid), Embase (Ovid), CINAHL, ISI Web of Science, and Africa journal online (AJOL). We analyzed the data descriptively. RESULTS: Thirty-three studies, conducted in 10 African countries (South Africa, Nigeria, Ghana, Kenya, Cameroon, Democratic Republic of Congo, Ethiopia, Malawi, Rwanda, and Uganda) were eligible for inclusion. There were few randomized controlled trials (n = 6; 18.2%), and tasks were mostly shifted for hypertension (n = 27; 81.8%) than for diabetes (n = 16; 48.5%). More tasks were shifted to nurses (n = 19; 57.6%) than pharmacists (n = 6; 18.2%) or community health workers (n = 5; 15.2%). Across all studies, the most common role played by HRH in task shifting was for treatment and adherence (n = 28; 84.9%) followed by screening and detection (n = 24; 72.7%), education and counselling (n = 24; 72.7%), and triage (n = 13; 39.4%). Improved blood pressure levels were reported in 78.6%, 66.7%, and 80.0% for hypertension-related task shifting roles to nurses, pharmacists, and CHWs, respectively. Improved glycaemic indices were reported as 66.7%, 50.0%, and 66.7% for diabetes-related task shifting roles to nurses, pharmacists, and CHWs, respectively. CONCLUSION: Despite the numerus HRH challenges that are present in Africa for CV and kidney health, this study suggests that task shifting initiatives can improve process of care measures (access and efficiency) as well as identification, awareness and treatment of CV and kidney disease in the region. The impact of task shifting on long-term outcomes of kidney and CV diseases and the sustainability of NCD programs based on task shifting remains to be determined.

A "happy" toddler presenting with sudden, life-threatening seizures.

Angelman syndrome is often associated with medically refractory epilepsy. Here, we report the case of a young girl with Angelman syndrome who experienced frequent and prolonged atonic seizures associated with dysautonomia and was unresponsive to multiple antiepileptic drugs, but who responded dramatically to the ketogenic diet. Clinicians are encouraged to consider the ketogenic diet early in the treatment course of patients with Angelman syndrome.

Nutrient intakes and physical growth of children with phenylketonuria undergoing nutrition therapy.

OBJECTIVE: To evaluate nutrient intakes, plasma phenylalanine (PHE) and tyrosine (TYR) concentrations, and physical growth of children with phenylketonuria undergoing nutrition management. DESIGN: Children were fed three different medical foods during a one-year study. Subjects/setting Children were evaluated at baseline and every three months in metabolic clinics. Children's diets were managed at home. Statistical analyses Intakes of medical foods and nutrients, number of diaries with nutrients <67% and <100% of Recommended Dietary Intakes (RDI), and mean plasma PHE and TYR concentrations were compared among groups using two-way ANOVA. chi-squared test compared the percentage of plasma PHE and TYR concentrations in each group in specific categories. Height and body mass index were plotted against National Center for Health Statistics reference data; means were compared among groups. Tukey's test compared groups with significant treatment effects. RESULTS: Mean intakes of nutrients, except energy by all groups and vitamin B-12 by the Periflex-fed group, met or exceeded RDIs. The oldest children tended to have the highest PHE intakes and plasma PHE concentrations. Mean length or height z score indicated normal linear growth. Mean body mass index z scores at study end suggested many children were overweight. APPLICATIONS: Dietitians should prescribe adequate medical food and encourage children with phenylketonuria to ingest all prescribed daily. Linear growth of children, where mean protein equivalent intakes ranged from 113% to 129% of RDI, was normal, demonstrating the need for a protein intake greater than RDIs when an elemental diet is the primary protein source. Dietitians should prescribe and carefully monitor energy intake, physical activity, and weight.
