Background The dietary shift from indigenous and traditional plants (ITPs) to cash crops and exotic plant food sources increases the risk of malnutrition and other nutrition-related non-communicable diseases, especially in poor rural communities. Farm communities in South Africa have been associated with poor nutritional status and extreme poverty. ITPs have been found to be affordable sources of several micronutrients. However, knowledge of and the use of these plants are declining, and little is known about the child’s acceptance of dishes prepared with ITPs. This knowledge can be used to improve the general acceptance of ITPs. This study aimed to gain insight into parents’ knowledge and perceptions and their use of ITPs in a farming community in the North West Province and to assess children’s acceptance of and preference for dishes made with African leafy vegetables (ALVs) and Swiss chard. Methods Parents (n = 29) responsible for food preparation for children in grade 2 to 4 in two schools were purposively selected for four focus group discussions. A sensory evaluation assessed the children’s (n = 98) acceptance of, preference for and intended consumption of dishes made with leafy vegetables. The dishes were made of Amaranthus spp ., Cleome gynandra , Cucurbita maxima , Vigna unguiculata and Beta vulgaris . Results Parents mentioned 30 edible ITPs during the focus group discussions. Parents had knowledge of available ITPs and their use as food. Location, seasonal variation and rainfall affected the availability of and access to ITPs. Sun-dried ITPs were stored in sacks for later use. ITPs were perceived as healthy, affordable and delicious, hence acceptable to the parents. The children also evaluated the dishes made with ALVs as acceptable in terms of colour, smell and taste. Swiss chard was preferred, most likely because of the children’s exposure to this vegetable. Children indicated that they would like to eat these leafy vegetables twice a week. Conclusion These results look promising for the promotion of ITPs as a strategy to reduce malnutrition in rural farm communities and for potential inclusion of these micronutrient-rich ALVs in school feeding programmes to improve the nutritional status of children.

A randomized controlled trial was conducted to assess the effect of African leafy vegetable (ALV) consumption on Fe, Zn and vitamin A status in children. Children were randomly allocated to receive either a 300 g cooked ALV dish and school meal starch (n 86) or the normal school meal (n 81) five times per week for three months. ALV in the dish consisted mainly of Amaranthus cruentus (at least 80 %) and the remainder of Cleome gynandra, Cucurbita maxima or Vigna unguiculata. Nutrient content and consumer acceptance of the ALV dish were also determined. North West Province, South Africa. Grade R to grade 4 children (6-12 years old) of two farm schools. The ALV dish contributed 11·6-15·8 mg Fe and 1·4-3·7 mg Zn. At baseline, prevalence of deficiencies in the intervention group was 16·0 %, 16·3 %, 7·0 % and 75·6 %, respectively, for anaemia (Hb<11·5 g/dl), Fe (serum ferritin<15 µg/l), vitamin A (serum retinol<20 μg/dl) and Zn (serum Zn<65 μg/dl); and in the control group 10·5 %, 18·5 %, 2·5 % and 75·3 %, respectively. No significant estimated intervention effect was found. This randomized controlled trial showed that ALV were unable to improve serum retinol, serum ferritin or Hb if there are only mild deficiencies present. Furthermore, despite the low Zn status in the study population, ALV consumption did not improve serum Zn concentrations either.

BackgroundThe prostatic urethra is conventionally resected during robot-assisted radical prostatectomy (RARP). We describe the technical feasibility and urinary continence outcomes of extended prostatic urethral preservation (EPUP) during RARP.MethodsA single surgeon at a National Comprehensive Cancer Network institute performed 48 consecutive RARP operations using EPUP from March 2014 to March 2016, during which time 177 conventional non-EPUP RARP operations were performed by other surgeons. Prior to this period, the EPUP surgeon had performed 17 non-EPUP RARP operations over 15 months. Total intracorporeal urethral length (IUL) preserved during EPUP was measured intraoperatively. Associations of EPUP and IUL with continence recovery rates and/or times were tested in Fisher’s exact and log rank univariate analyses and Cox logistic regression multivariable analyses.ResultsMedian IUL preserved during EPUP was 4.0 cm (range 2.5–6.0 cm), and urethral dissections typically spanned the prostatic apex to mid-gland or base. Seven-week continence rates were significantly higher with versus without EPUP. EPUP patient rates of using 0 or 0–1 pads per day immediately after catheter removal were 19% and 35%, respectively. These rates increased significantly (53% and 76%, respectively), as did the IUL preserved (median 5.0 cm), among more recent EPUP patients (n = 17), which suggested a learning curve. In multivariable analyses including all patients, an EPUP approach was an independent predictor of faster continence recovery. In multivariable analyses of the EPUP subset, a longer IUL preserved was independently associated with faster continence recovery. No EPUP patient had a urethral fossa positive margin, and apical positive margins were similarly infrequent among EPUP and non-EPUP patients.ConclusionsEPUP is technically feasible during RARP and associated with faster continence recovery. Future investigation into the generalizability of these findings and the oncologic safety of EPUP is warranted.

Lactating women and their infants are susceptible to iodine deficiency and iodine excess. In South Africa, no data exist on the iodine status and thyroid function of these vulnerable groups. In a cross-sectional study, urinary iodine concentrations (UIC), thyroid function, and breast-milk iodine concentrations (BMIC) were assessed in 100 lactating women from a South African township and their 2-4-month-old breastfed infants. Potential predictors of UIC, thyroid function, and BMIC, including household salt iodine concentrations (SIC) and maternal sodium excretion, were also investigated. The median (25th-75th percentile) UIC was 373 (202-627) μg/L in infants and 118 (67-179) μg/L in mothers. Median household SIC was 44 (27-63) ppm. Household SIC and maternal urinary sodium excretion predicted UIC of lactating mothers. Median BMIC was 179 (126-269) μg/L. Age of infants, SIC, and maternal UIC predicted BMIC. In turn, infant age and BMIC predicted UIC of infants. Forty-two percent of SIC values were within the South African recommended salt iodine fortification level at production of 35-65 ppm, whilst 21% of SIC were >65 ppm. Thyroid-stimulating hormone, total thyroxine, and thyroglobulin concentrations in the dried whole blood spot specimens from the infants were 1.3 (0.8-1.9) mU/L, 128±33 mmol/L, and 77.1 (56.3-105.7) μg/L, respectively, and did not correlate with infant UIC or BMIC. Our results suggest that the salt fortification program in South Africa provides adequate iodine to lactating women and indirectly to their infants via breast milk. However, monitoring of salt iodine content of the mandatory salt iodization program in South Africa is important to avoid over-iodization of salt.

Adequate intake of iodine is important during pregnancy because of its essential role in foetal growth and neurodevelopment. Data on iodine status of South African pregnant women are scarce, and the salt reduction policy implemented in 2016 may decrease iodine intake of South Africans. This cross‐sectional study assessed the iodine status of pregnant women residing in urban Johannesburg, South Africa. A total of 250 pregnant women were enrolled into the ‘Nutrition during Pregnancy and Early Development’ (NuPED) study and 312 pregnant women into the ‘Assessment of dried blood spot thyroglobulin in pregnant women to redefine the range of median urinary iodine concentration that indicates adequate iodine intake, South Africa’ (STRIPE‐SA) study and were included in this analysis. Urinary iodine concentration (UIC) was analysed in a spot urine sample. Thyroglobulin (Tg) was measured in serum, and thyroid‐stimulating hormone (TSH) and total thyroxine (tT4) were measured in dried blood spots. The median [interquartile range (IQR)] UIC of pregnant women was 144 (84–234) μg/L. Women in the first (n = 99), second (n = 262) and third (n = 174) trimester had a median UIC of 133 (81–316), 145 (84–236) and 156 (89–245) μg/L, respectively (p = 0.419). Median TSH, tT4 and Tg were 2.7 (2.3–3.2) mU/L, 202 (163–236) nmol/L and 9.2 (5.4–17.9) μg/L, respectively. Based on the median UIC, pregnant women residing in urban Johannesburg may be borderline iodine deficient. These findings highlight the need for ongoing monitoring of iodine status among vulnerable pregnant women, especially considering the recently introduced salt reduction policy in South Africa.

A genome-wide association study in Ghana, West Africa, to identify genetic variants associated with malaria pathogenesis reveals two previously unknown loci on chromosomes 1 and 16. Genetic signals of malaria resistance This genome-wide association study in 2,645 cases and 3,050 controls from Ghana in West Africa identifies genetic variants that might affect any one of the many steps in malaria pathogenesis. Two novel loci are described. The first is on chromosome 1, in the vicinity of the ATP2B4 gene, which encodes the main calcium pump of erythrocytes, the host cells of the pathogenic stage of the malaria parasite. The second is on chromosome 16, close to MARVELD3, which encodes a tight-junction protein that is expressed on endothelial cells. These genetic variants may confer resistance by affecting key steps in disease development that could generate possible antimalarial targets. Malaria causes approximately one million fatalities per year, mostly among African children 1 . Although highlighted by the strong protective effect of the sickle-cell trait 2 , 3 , the full impact of human genetics on resistance to the disease remains largely unexplored 4 . Genome-wide association (GWA) studies are designed to unravel relevant genetic variants comprehensively; however, in malaria, as in other infectious diseases, these studies have been only partly successful 5 . Here we identify two previously unknown loci associated with severe falciparum malaria in patients and controls from Ghana, West Africa. We applied the GWA approach to the diverse clinical syndromes of severe falciparum malaria, thereby targeting human genetic variants influencing any step in the complex pathogenesis of the disease. One of the loci was identified on chromosome 1q32 within the ATP2B4 gene, which encodes the main calcium pump of erythrocytes 6 , the host cells of the pathogenic stage of malaria parasites. The second was indicated by an intergenic single nucleotide polymorphism on chromosome 16q22.2, possibly linked to a neighbouring gene encoding the tight-junction protein MARVELD3. The protein is expressed on endothelial cells 7 and might therefore have a role in microvascular damage caused by endothelial adherence of parasitized erythrocytes. We also confirmed previous reports on protective effects of the sickle-cell trait and blood group O 5 , 8 , 9 . Our findings underline the potential of the GWA approach to provide candidates for the development of control measures against infectious diseases in humans.

Many African countries have a shortage of health workers. As a response, in 2012, the Ministers of Health in the WHO African Region endorsed a Regional Road Map for Scaling Up the Health Workforce from 2012 to 2025. One of the key milestones of the roadmap was the development of national strategic plans by 2014. It is important to assess the extent to which the strategic plans that countries developed conformed with the WHO Roadmap. We examine the strategic plans for human resource for health (HRH) of sub-Saharan African countries in 2015 and assess the extent to which they take into consideration the WHO African Region’s Roadmap for HRH. A questionnaire seeking data on human resources for health policies and plans was sent to 47 Member States and the responses from 43 countries that returned the questionnaires were analysed. Only 72% had a national plan of action for attaining the HRH target. This did not meet the 2015 target for the WHO, Regional Office for Africa’s Roadmap. The plans that were available addressed the six areas of the roadmap. Despite all their efforts, countries will need further support to comprehensively implement the six strategic areas to maintain the health workers required for universal health coverage

Bacterial infections of livestock threaten the sustainability of agriculture and public health through production losses and contamination of food products. While prophylactic and therapeutic application of antibiotics has been successful in managing such infections, the evolution and spread of antibiotic-resistant strains along the food chain and in the environment necessitates the development of alternative or adjunct preventive and/or therapeutic strategies. Additionally, the growing consumer preference for “greener” antibiotic-free food products has reinforced the need for novel and safer approaches to controlling bacterial infections. The use of bacteriophages (phages), which can target and kill bacteria, are increasingly considered as a suitable measure to reduce bacterial infections and contamination in the food industry. This review primarily elaborates on the recent veterinary applications of phages and discusses their merits and limitations. Furthermore, using Streptococcus suis as a model, we describe the prevalence of prophages and the anti-viral defence arsenal in the genome of the pathogen as a means to define the genetic building blocks that are available for the (synthetic) development of phage-based treatments. The data and approach described herein may provide a framework for the development of therapeutics against an array of bacterial pathogens.

Given the complex nature of the UN’s Sustainable Development Goals (SDGs), there are increasing calls for new inclusive and bottom-up governance mechanisms in building a relationship between governments and their citizens, in particular, the youth, to localise the 2030 Agenda. But such successful bottom-up multi-stakeholder engagement tools have yet to emerge in practice. Hence, of specific interest in this study is exploring bottom-up approaches useful for localising the SDGs and harnessing real transformative change to leave no one behind by 2030. Using a case study from the UK, we present a novel integrated mechanism to achieve this. An integrated Social Innovation (SI) and Scenarios Thinking (ST) mechanism remains a valuable bottom-up tool capable of empowering citizens, including the youth and decision-makers in delivering coherent SDGs plans, policies, and programmes. The study reveals that although the SDGs are distinct, they are also interconnected. A scenario development workshop with youth with no prior knowledge of the SDGs showed a common thread of policy measures for different SDG future images. Standard policy measures amongst different SDGs call for an equitable society at all levels; that all energy sources be from clean and renewable sources; investment in low-carbon technologies and research; and financial support for promoting sustainable transportation and consumption measures. This study highlights that we need to change how we think and talk about SDGs and recommends socially innovative steps to embrace cross-sectoral and nexus thinking as the backdrop of the citizen science concept. We conclude that the SDGs should not become a performative exercise or failed social experiment. And any practical localisation from the UN’s Member States across the northern and southern hemispheres will require robust measures addressing future-oriented systemic thinking, inclusivity and good governance, together with standards for community resilience and sustainability.
