Background Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anomalies in low-income, middle-income, and high-income countries globally, and identified factors associated with mortality. MethodsWe did a multicentre, international prospective cohort study of patients younger than 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung's disease. Recruitment was of consecutive patients for a minimum of 1 month between October, 2018, and April, 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using the REDCap platform. Patients were followed up for 30 days after primary intervention, or 30 days after admission if they did not receive an intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We did a complete case analysis. FindingsWe included 3849 patients with 3975 study conditions (560 with oesophageal atresia, 448 with congenital diaphragmatic hernia, 681 with intestinal atresia, 453 with gastroschisis, 325 with exomphalos, 991 with anorectal malformation, and 517 with Hirschsprung's disease) from 264 hospitals (89 in high-income countries, 166 in middleincome countries, and nine in low-income countries) in 74 countries. Of the 3849 patients, 2231 (58•0%) were male. Median gestational age at birth was 38 weeks (IQR 36-39) and median bodyweight at presentation was 2•8 kg (2•3-3•3). Mortality among all patients was 37 (39•8%) of 93 in low-income countries, 583 (20•4%) of 2860 in middle-income countries, and 50 (5•6%) of 896 in high-income countries (p<0•0001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (nine [90•0%] of ten in lowincome countries, 97 [31•9%] of 304 in middle-income countries, and two [1•4%] of 139 in high-income countries; p≤0•0001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included country income status (low-income vs high-income countries, risk ratio 2•78 [95% CI 1•88-4•11], p<0•0001; middle-income vs high-income countries, 2•11 [1•59-2•79], p<0•0001), sepsis at presentation (1•20 [1•04-1•40], p=0•016), higher American Society of Anesthesiologists (ASA) score at primary intervention (ASA 4-5 vs ASA 1-2, 1•82 [1•40-2•35], p<0•0001; ASA 3 vs ASA 1-2, 1•58, [1•30-1•92], p<0•0001]), surgical safety checklist not used (1•39 [1•02-1•90], p=0•035), and ventilation or parenteral nutrition unavailable when needed (ventilation 1•96, [1•4...

BackgroundAga Khan University is developing its undergraduate medical education curriculum for East Africa. In Kenya, a 1 year internship is mandatory for medical graduates’ registration as practitioners. The majority of approved internship training sites are at district hospitals. The purposes of this study were to determine: (1) whether recent Kenyan medical graduates are prepared for their roles as interns in district hospitals upon graduation from medical school; (2) what working and training conditions and social support interns are likely to face in district hospital; and (3) what aspects of the undergraduate curriculum need to be addressed to overcome perceived deficiencies in interns’ competencies.MethodsFocus group discussions and semi-structured interviews were conducted with current interns and clinical supervisors in seven district hospitals in Kenya. Perceptions of both interns and supervisors regarding interns’ responsibilities and skills, working conditions at district hospitals, and improvements required in medical education were obtained.ResultsFindings included agreement across informants on deficiencies in interns’ practical skills and experience of managing clinical challenges. Supervisors were generally critical regarding interns’ competencies, whereas interns were more specific about their weaknesses. Supervisor expectations were higher in relation to surgical procedures than those of interns. There was agreement on the limited learning, clinical facilities and social support available at district hospitals including, according to interns, inadequate supervision. Supervisors felt they provided adequate supervision and that interns lacked the ability to initiate communication with them. Both groups indicated transition challenges from medical school to medical practice attributable to inadequate practical experience. They indicated the need for more direct patient care responsibilities and clinical experience at a district hospital during undergraduate training.ConclusionPerception of medical graduates’ unpreparedness seemed to stem from a failure to implement the apprenticeship model of learning in medical school and lack of prior exposure to district hospitals. These findings will inform curriculum development to meet stakeholder requirements, improve the quality of graduates, and increase satisfaction with transition to practice.

Globally, obesity is considered an epidemic due to an increase in its prevalence and severity especially among young children and adolescents. This nutritional disorder is not limited to affluent countries as it is becoming increasingly prevalent in developing countries. Obesity is associated not only with cardiovascular, endocrine, gastrointestinal, orthopedic, and respiratory diseases, but also with psychological complications, implying a problem of far-reaching consequences for health and health services. Recently, evidence-based studies have shown that the duration of exclusive breastfeeding and the type of complementary feeds during the weaning period of an infant may have an effect on overnutrition later on in life. Thus, stemming the tide of obesity early on in life would potentially decrease the prevalence and complications of adult obesity, which could have significant implications for health care and the economy at large. This review explores the role of complementary feeding in obesity and approaches to prevention and treatment of childhood obesity by summarizing key systematic reviews. In conclusion, we found that although the relationship between complementary feeding and childhood obesity has been suspected for a long time, specific risk parameters are not as firmly established. Early introduction of complementary feeds (before the 4th month of life), high protein and energy content of feeds, and nonadherence to feeding guidelines may be associated with overweight and obesity later in life.

BackgroundIn order to accurately interpret neonatal thyroid function tests (TFTs), it is necessary to have population specific reference intervals (RIs) as there is significant variation across different populations possibly due to genetic, environmental or analytical issues. Despite the importance of RIs, globally there are very few publications on RIs for neonatal TFTs primarily due to ethical and technical issues surrounding recruitment of neonates for a prospective study. To the best of our knowledge, this is the first report from Africa on neonatal RIs for TFTs.MethodsWe used hospital based data largely derived from neonates attending the wellness clinic at the Aga Khan University Hospital Nairobi (AKUHN) where screening for congenital hypothyroidism is routinely done. Specifically we derived age and gender stratified RIs for free thyroxine (fT4) and thyroid stimulating hormone (TSH) which had been analyzed on a Roche e601 analyzer from 2011 to 2013. Determination of reference intervals was done using a non-parametric method.ResultsA total of 1639 and 1329 non duplicate TSH and fT4 values respectively were used to derive RIs. There was a decline in TSH and fT4 levels with increase in age. Compared to the Roche RIs, the derived RIs for TSH in neonates aged 0–6 days and those aged 7–30 days had lower upper limits and narrower RIs. The fT4 lower limits for neonates less than 7 days and those aged 7–30 days were higher than those proposed by Roche. There was a significant difference in TSH RIs between male and female neonates aged less than 15 days. No gender differences were seen for all other age stratifications for both TSH and fT4. Appropriate age and gender specific RIs were subsequently determined.ConclusionThe AKUHN derived RIs for fT4 and TSH revealed similar age related trends to what has been published. However, the differences seen in upper and lower limits across different age stratifications when compared to the Roche RIs highlight the need for population specific RIs for TFTs especially when setting up a screening programme for congenital hypothyroidism. We subsequently recommend the adoption of the derived RIs by the AKUHN laboratory and hope that the RIs obtained can serve as a reference for the African population.
