Establishing a postgraduate programme in nutritional epidemiology to strengthen resource capacity, academic leadership and research in the democratic republic of Congo
Background
Low- and Middle-income countries (LMIC) face considerable health and nutrition challenges, many of which can be addressed through strong academic leadership and robust research translated into evidence-based practice. A North-South-South partnership between three universities was established to implement a masterâs programme in nutritional epidemiology at the Kinshasa School of Public Health (KSPH), Democratic Republic of Congo (DRC). The partnership aimed to develop academic leadership and research capacity in the field of nutrition in the DRC. In this article we describe the educational approach and processes used, and discuss successes, challenges, and lessons learned.
Methods
Self-administered questionnaires, which included both open and closed questions, were sent to all graduates and students on the masterâs programme to explore studentsâ experiences and perceptions of all aspects of the educational programme. Quantitative data was analysed using frequencies, and a thematic approach was used to analyse responses to open-ended questions.
Results
A two-year masterâs programme in Nutritional Epidemiology was established in 2014, and 40 students had graduated by 2020. Key elements included using principles of authentic learning, deployment of students for an internship at a rural residential research site, and support of selected students with bursaries. Academic staff from all partner universities participated in teaching and research supervision.
The curriculum and teaching approach were well received by most students, although a number of challenges were identified. Most students reported benefits from the rural internship experience but were challenged by the isolation of the rural site, and felt unsupported by their supervisors, undermining studentsâ experiences and potentially the quality of the research. Financial barriers were also reported as challenges by students, even among those who received bursaries.
Conclusion
The partnership was successful in establishing a Master Programme in Nutritional Epidemiology increasing the number of nutrition researchers in the DRC. This approach could be used in other LMIC settings to address health and nutrition challenges.publishedVersio
âI am not only beneficial to the community but to the entire country, I am trained as a researcher nowâ: Developing health research skills in low-income countries
Partnerships between Higher Education Institutions in the global South and North have potential for building capacity in public health research in low-resource countries. We present experiences of partners involved in a NorthâSouthâSouth partnership between universities in Norway, the Democratic Republic of Congo (DRC) and South Africa. The partnership aimed to establish a postgraduate programme in nutritional epidemiology at the University of Kinshasa, DRC, and develop a cadre of researchers and academic leaders to provide locally generated health research to inform policy. In-depth interviews were conducted with 31 purposively selected stakeholders, facilitators, and students from partner institutions. All participants expressed positive experiences, indicating that the partnership provided excellent opportunities to network, enriched participantsâ learning and enhanced academic growth, with benefits at individual, institutional, and country levels. Participants suggested that maintaining a common vision was important for success, facilitated by joint planning of project activities, focussing strongly on building research and academic capacity at Kinshasa School of Public Health and addressing local nutrition problems. Important challenges highlighted for future partnerships included failures of co-facilitation and co-supervision, poor research dissemination and policy impact, and concerns about sustainability. Notwithstanding, NorthâSouthâSouth partnerships can address skills shortages in public health research with significant benefits to all partner institutions.publishedVersio
Reshaping Antibody Diversity
SummarySome species mount a robust antibody response despite having limited genome-encoded combinatorial diversity potential. Cows are unusual in having exceptionally long CDR H3 loops and few V regions, but the mechanism for creating diversity is not understood. Deep sequencing reveals that ultralong CDR H3s contain a remarkable complexity of cysteines, suggesting that disulfide-bonded minidomains may arise during repertoire development. Indeed, crystal structures of two cow antibodies reveal that these CDR H3s form a very unusual architecture composed of a β strand âstalkâ that supports a structurally diverse, disulfide-bonded âknobâ domain. Diversity arises from somatic hypermutation of an ultralong DH with a severe codon bias toward mutation to cysteine. These unusual antibodies can be elicited to recognize defined antigens through the knob domain. Thus, the bovine immune system produces an antibody repertoire composed of ultralong CDR H3s that fold into a diversity of minidomains generated through combinations of somatically generated disulfides
Profiting from an inefficient association football gambling market: Prediction, risk and uncertainty using Bayesian networks
AbstractWe present a Bayesian network (BN) model for forecasting Association Football match outcomes. Both objective and subjective information are considered for prediction, and we demonstrate how probabilities transform at each level of model component, whereby predictive distributions follow hierarchical levels of Bayesian inference. The model was used to generate forecasts for each match of the 2011/2012 English Premier League (EPL) season, and forecasts were published online prior to the start of each match. Profitability, risk and uncertainty are evaluated by considering various unit-based betting procedures against published market odds. Compared to a previously published successful BN model, the model presented in this paper is less complex and is able to generate even more profitable returns
Translating new evidence into clinical practice: A quasi-experimental controlled before-after study evaluating the effect of a novel outreach mentoring approach on knowledge, attitudes and confidence of health workers providing HIV and infant feeding counselling in South Africa
Objectives We report the effectiveness of a mentoring approach to improve health workers' (HWs') knowledge, attitudes and confidence with counselling on HIV and infant feeding. Design Quasi-experimental controlled before-after study. Setting Randomly selected primary healthcare clinics (n=24 intervention, n=12 comparison); two districts, South Africa. Participants All HWs providing infant feeding counselling in selected facilities were invited. Interventions Three 1-2 hours, on-site workshops over 3-6 weeks. Primary outcome measures Knowledge (22 binary questions), attitude (21 questions-5-point Likert Scale) and confidence (19 questions-3-point Likert Scale). Individual item responses were added within each of the attitude and confidence domains. The respective sums were taken to be the domain composite index and used as a dependent variable to evaluate intervention effect. Linear regression models were used to estimate the mean score difference between intervention and comparison groups postintervention, adjusting for the mean score difference between them at baseline

A hierarchical bayesian analysis of parasite prevalence and sociocultural outcomes: The role of structural racism and sanitation infrastructure
Objectives: We conduct a revaluation of the Thornhill and Fincher research project on parasites using finely- resolved geographic data on parasite prevalence, individual-level sociocultural data, and multilevel Bayesian modeling. In contrast to the evolutionary psychological mechanisms linking parasites to human behavior and cultural character- istics proposed by Thornhill and Fincher, we offer an alternative hypothesis that structural racism and differential access to sanitation systems drive both variation in parasite prevalence and differential behaviors and cultural characteristics.Methods: We adopt a Bayesian framework to estimate parasite prevalence rates in 51 districts in eight Latin Ameri- can countries using the disease status of 170,220 individuals tested for infection with the intestinal roundworm Ascaris lumbricoides (HuâŹrlimann et al., [2011]: PLoS Negl Trop Dis 5:e1404). We then use district-level estimates of parasite prevalence and individual-level social data from 5,558 individuals in the same 51 districts (Latinobar?ometro, 2008) to assess claims of causal associations between parasite prevalence and sociocultural characteristics.Results: We find, contrary to Thornhill and Fincher, that parasite prevalence is positively associated with preferen- ces for democracy, negatively associated with preferences for collectivism, and not associated with violent crime rates or gender inequality. A positive association between parasite prevalence and religiosity, as in Fincher and Thornhill (2012: Behav Brain Sci 35:61â79), and a negative association between parasite prevalence and achieved education, as predicted by Eppig et al. (2010: Proc R S B: Biol Sci 277:3801â3808), become negative and unreliable when reasonable controls are included in the model. We find support for all predictions derived from our hypothesis linking structural racism to both parasite prevalence and cultural outcomes.Conclusions: We conclude that best practices in biocultural modeling require examining more than one hypothesis, retaining individual-level data and its associated variance whenever possible, and adopting multilevel techniques suited to the structuring of the data
Health risk behaviours among adolescents in the English-speaking Caribbean: a review
<p>Abstract</p> <p>Background</p> <p>The aim of this paper was to review and summarize research on prevalence of health risk behaviours, their outcomes as well as risk and protective factors among adolescents in the English-speaking Caribbean.</p> <p>Methods</p> <p>Searching of online databases and the World Wide Web as well as hand searching of the <it>West Indian Medical Journal </it>were conducted. Papers on research done on adolescents aged 10 â 19 years old and published during the period 1980 â 2005 were included.</p> <p>Results</p> <p>Ninety-five relevant papers were located. Five papers were published in the 1980s, 47 in the 1990s, and from 2000â2005, 43 papers. Health risk behaviours and outcomes were divided into seven themes. Prevalence data obtained for these, included lifetime prevalence of <b>substance use</b>: cigarettes-24% and marijuana-17%; <b>high risk sexual behaviour</b>: initiation of sexual activity ⤠10 years old-19% and those having more than six partners-19%; <b>teenage pregnancy</b>: teens account for 15â20% of all pregnancies and one-fifth of these teens were in their second pregnancy; <b>Sexually-Transmitted Infections (STIs)</b>: population prevalence of gonorrhoea and/or chlamydia in 18â21 year-olds was 26%; <b>mental health</b>: severe depression in the adolescent age group was 9%, and attempted suicide-12%; <b>violence and juvenile delinquency</b>: carrying a weapon to school in the last 30 days-10% and almost always wanting to kill or injure someone-5%; <b>eating disorders and obesity</b>: overweight-11%, and obesity-7%. Many of the risk behaviours in adolescents were shown to be related to the adolescent's family of origin, home environment and parent-child relationships. Also, the protective effects of family and school connectedness as well as increased religiosity noted in studies from the United States were also applicable in the Caribbean.</p> <p>Conclusion</p> <p>There is a substantial body of literature on Caribbean adolescents documenting prevalence and correlates of health risk behaviours. Future research should emphasize the designing and testing of interventions to alleviate this burden.</p
