Project description:BackgroundBetween 2008 and 2013, the West African Health Organisation (WAHO) conducted a series of post-graduate capacity building in research methodology in West Africa. This work evaluated the contribution of these trainings in terms of knowledge acquisition and influence of research and policy practice. Cooke's conceptual framework for assessing research capacity building was used with three data sources to construct the indicators (training reports, research project implementation reports and WAHO research programme evaluation report).ResultsThere was an improvement in the knowledge of the 84 participants between the pre- and post-test. At the end of the training, the learners developed 19 protocols, 14 of which were finalised, financed and implemented, reflecting the learners' confidence to engage in research at the end of the training. The implementation of the protocols was conducted with the partnership and collaboration between the agents of the control programmes and the research centres. Some research results have been disseminated and a small portion used to strengthen the programmes.ConclusionThis evaluation showed that the training was linked to practice with little publication and use of the results to improve the programmes. This regional capacity building programme should be maintained and strengthened by adding modules in data analysis, scientific communication and knowledge transfer.

Project description:BackgroundThe first case of the novel coronavirus disease-2019 (COVID-19) in West Africa was first confirmed in Nigeria in February 2020. Since then, several public health interventions and preventive measures have been implemented to curtail transmission of the causative agent, the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Therefore, this study was performed to assess the knowledge, attitudes, and perceptions of West Africans towards COVID-19.MethodsAn online survey was conducted between 29 September to 29 October 2020 among West Africans. Thirty-three survey questions were designed to collect sociodemographic data and participants' knowledge, attitude and perception towards COVID-19. The study targeted all West African nationals who were 18 years and above, and willing to participate in the study. Participants were either in-country or abroad.ResultsOverall, 1106 respondents (≥18 years) from 16 West African countries, with about 12.1% of them residing outside the West African subregion, participated in the survey. The respondents had an average COVID-19 knowledge score of 67.82 ± 8.31, with knowledge of the disease significantly associated with the country of residence (p = 0.00) and marginally (p = 0.05) so with settlement types (i.e., urban, suburban and rural areas). Most respondents (93.4%) could identify the main COVID-19 symptoms, and 73.20% would consult a healthcare professional if infected with SARS-CoV-2. Also, 75.2% of the respondents are willing to receive the COVID-19 vaccine, whereas 10.40% and 14.40% are unwilling and undecided, respectively. Perceptions of what constitute COVID-19 preventive measures were highly variable. Approximately, 8% of the respondents felt that their government responded excellently in managing the pandemic while a third felt that the response was just good. Also, more than half (54%) opined that isolation and treatment of COVID-19 patients is a way of curbing SARS-CoV-2 spread.ConclusionsMost West Africans have basic knowledge of COVID-19 and showed a positive attitude, with likely proactive practice towards the disease. However, results showed that these varied across countries and are influenced by the types of settlements. Therefore, the health and education authorities in various countries should develop focused measures capturing people in different settlements to improve their preventative measures when designing public health interventions for COVID-19 and any future epidemics or pandemics.

Project description:Background and purposeStroke in lower and middle-income countries affects a young and productive age group. Data on factors associated with stroke in the young are sorely lacking from lower and middle-income countries. Our objective is to characterize the nature of stroke and its risk factors among young West Africans aged <50 years old.MethodsThe SIREN (Stroke Investigative Research and Educational Network) is a multicenter, case-control study involving 15 sites in Nigeria and Ghana. Cases included adults aged ≥18 years with computed tomography/magnetic resonance imaging-confirmed stroke. Controls were age-and gender-matched stroke-free adults recruited from the communities in catchment areas of cases. Comprehensive evaluation for vascular, lifestyle, and psychosocial factors was performed. We used conditional logistic regression to estimate odds ratios and population attributable risks with 95% confidence intervals.ResultsFive hundred fifteen (24.3%) out of 2118 cases enrolled were <50 years old. Among subjects <50 years old, hemorrhagic stroke proportion was 270 (52.5%) versus 245 (47.5%) for ischemic strokes. Etiologic subtypes of ischemic strokes included large artery atherosclerosis (40.0%), small vessel disease (28.6%), cardioembolism (11.0%), and undetermined (20.4%). Hypertension (91.7%), structural lesions (3.4%), and others (4.9%) were causally associated with hemorrhagic stroke. Six topmost modifiable factors associated with stroke in descending order of population attributable risk (95% confidence interval) were hypertension: 88.7% (82.5%-94.8%), dyslipidemia: 48.2% (30.6%-65.9%), diabetes mellitus: 22.6% (18.7%-26.5%), low green vegetable consumption: 18.2% (-6.8%-43.2%), stress: 14.5% (4.9%-24.1%), and cardiac disease: 8.4% (5.8%-11.1%).ConclusionsThe high and rising burden of stroke among young Africans should be curtailed via aggressive, population-wide vascular risk factor control.

Project description:Background and purposeTo identify the qualitative and quantitative contributions of conventional risk factors for occurrence of ischemic stroke and its key pathophysiologic subtypes among West Africans.MethodsThe SIREN (Stroke Investigative Research and Educational Network) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria. Cases include adults aged ≥18 years with ischemic stroke who were etiologically subtyped using the A-S-C-O-D classification into atherosclerosis, small-vessel occlusion, cardiac pathology, other causes, and dissection. Controls were age- and gender-matched stroke-free adults. Detailed evaluations for vascular, lifestyle, and psychosocial factors were performed. We used conditional logistic regression to estimate adjusted odds ratios with 95% CI.ResultsThere were 2431 ischemic stroke case and stroke-free control pairs with respective mean ages of 62.2±14.0 versus 60.9±13.7 years. There were 1024 (42.1%) small vessel occlusions, 427 (17.6%) large-artery atherosclerosis, 258 (10.6%) cardio-embolic, 3 (0.1%) carotid dissections, and 719 (29.6%) undetermined/other causes. The adjusted odds ratio (95% CI) for the 8 dominant risk factors for ischemic stroke were hypertension, 10.34 (6.91-15.45); dyslipidemia, 5.16 (3.78-7.03); diabetes, 3.44 (2.60-4.56); low green vegetable consumption, 1.89 (1.45-2.46); red meat consumption, 1.89 (1.45-2.46); cardiac disease, 1.88 (1.22-2.90); monthly income $100 or more, 1.72 (1.24-2.39); and psychosocial stress, 1.62 (1.18-2.21). Hypertension, dyslipidemia, diabetes were confluent factors shared by small-vessel, large-vessel and cardio-embolic subtypes. Stroke cases and stroke-free controls had a mean of 5.3±1.5 versus 3.2±1.0 adverse cardio-metabolic risk factors respectively (P<0.0001).ConclusionsTraditional vascular risk factors demonstrate important differential effect sizes with pathophysiologic, clinical and preventative implications on the occurrence of ischemic stroke among indigenous West Africans.

Project description:ObjectiveTo describe health equity research priorities for health care delivery systems and delineate a research and action agenda that generates evidence-based solutions to persistent racial and ethnic inequities in health outcomes.Data sources and study settingThis project was conducted as a component of the Agency for Healthcare Research and Quality's (AHRQ) stakeholder engaged process to develop an Equity Agenda and Action Plan to guide priority setting to advance health equity. Recommendations were developed and refined based on expert input, evidence review, and stakeholder engagement. Participating stakeholders included experts from academia, health care organizations, industry, and government.Study designExpert group consensus, informed by stakeholder engagement and targeted evidence review.Data collection/extraction methodsPriority themes were derived iteratively through (1) brainstorming and idea reduction, (2) targeted evidence review of candidate themes, (3) determination of preliminary themes; (4) input on preliminary themes from stakeholders attending AHRQ's 2022 Health Equity Summit; and (5) and refinement of themes based on that input. The final set of research and action recommendations was determined by authors' consensus.Principal findingsHealth care delivery systems have contributed to racial and ethnic disparities in health care. High quality research is needed to inform health care delivery systems approaches to undo systemic barriers and inequities. We identified six priority themes for research; (1) institutional leadership, culture, and workforce; (2) data-driven, culturally tailored care; (3) health equity targeted performance incentives; (4) health equity-informed approaches to health system consolidation and access; (5) whole person care; (6) and whole community investment. We also suggest cross-cutting themes regarding research workforce and research timelines.ConclusionsAs the nation's primary health services research agency, AHRQ can advance equitable delivery of health care by funding research and disseminating evidence to help transform the organization and delivery of health care.

Project description:Funded by the European Commission Horizon 2020 programme, the Lifepath research consortium aimed to investigate the effects of socioeconomic inequalities on the biology of healthy aging. The main research questions included the impact of inequalities on health, the role of behavioral and other risk factors, the underlying biological mechanisms, the efficacy of selected policies, and the general implications of our findings for theories and policies. The project adopted a life-course and comparative approach, considering lifetime effects from childhood and adulthood, and pooled data on up to 1.7 million participants of longitudinal cohort studies from Europe, USA, and Australia. These data showed that socioeconomic circumstances predicted mortality and functional decline as strongly as established risk factors currently targeted by global prevention programmes. Analyses also looked at socioeconomically patterned biological markers, allostatic load, and DNA methylation using richly phenotyped cohorts, unraveling their association with aging processes across the life-course. Lifepath studies suggest that socioeconomic circumstances are embedded in our biology from the outset-i.e., disadvantage influences biological systems from molecules to organs. Our findings have important implications for policy, suggesting that (a) intervening on unfavorable socioeconomic conditions is complementary and as important as targeting well-known risk factors, such as tobacco and alcohol consumption, low fruit and vegetable intake, obesity and a sedentary lifestyle, and that (b) effects of preventive interventions in early life integrate interventions in adulthood. The report has an executive summary that refers to the different sections of the main paper.

Project description:Schools offer a valuable setting to promote good health and mental well-being amongst young people. Schools are complex systems and therefore systems interventions are needed to improve pupil health and well-being. This paper presents a qualitative process evaluation of the South West- School Health Research Network, a systems level intervention. The evaluation is based on interviews with school staff, local authorities and wider stakeholders. Given the complexity of England's educational system there is a need to intervene and monitor health at multiple levels and to ensure close partnership working to effectively improve adolescent health through schools.

Project description:Data on safety and efficacy issues associated with natural health products and dietary supplements (NHP&S) remains largely cloistered within domain specific databases or embedded within general biomedical data sources. A major challenge in leveraging analytic approaches on such data is due to the inefficient ability to retrieve relevant data, which includes a general lack of interoperability among related sources. This study developed a thesaurus of NHP&S ingredient terms that can be used by existing biomedical natural language processing (NLP) tools for extracting information of interest. This process was evaluated relative to intervention name strings sampled from the United States Food and Drug Administration Adverse Event Reporting System (FAERS). A use case was used to demonstrate the potential to utilize FAERS for monitoring NHP&S adverse events. The results from this study provide insights on approaches for identifying additional knowledge from extant repositories of knowledge, and potentially as information that can be included into larger curation efforts.

Project description:IntroductionThe era of the Sustainable Development Goals calls for multidisciplinary research and intersectoral approaches to addressing health challenges. This presents a unique opportunity for multidisciplinary fields concerned with complex systems. Those working in system-oriented fields such as health policy and systems research (HPSR) and health services research must be forward-thinking in optimizing their collective ability to address these global challenges.ObjectivesThe objective of this commentary was to share reflections on challenges and strategies in managing the HPSR workforce in order to stimulate dialogue and cross-learning across similar fields.Strategies/findingsThe following strategies are discussed here: definitional clarity of expected competencies and coordination across HPS researchers, national investment in HPSR, institutional capacity for coproduction of knowledge across different types of actors, and participatory leadership.ConclusionsCreative approaches in training, financing, developing, and leading the diverse workforce required to strengthen health systems can pave the way for its full-time and part-time members to work together.

Project description:ContextAdiponectin, a hormone secreted by adipose tissue, has both metabolic and antiinflammatory properties. Although multiple studies have described the relationship between adiponectin and obesity in several human populations, no large studies have evaluated this relationship in Africans.ObjectiveWe investigated the relationship between adiponectin and measures of obesity, serum lipids, and insulin resistance in a large African cohort.DesignParticipants are from the Africa America Diabetes Mellitus (AADM) Study, a case-control study of genetic and other risk factors associated with development of type 2 diabetes in Africans.SettingPatients were recruited from five academic medical centers in Nigeria and Ghana (Accra and Kumasi in Ghana and Enugu, Ibadan, and Lagos in Nigeria) over 10 yr.Main outcome measuresCirculating adiponectin levels were measured in 690 nondiabetic controls using an ELISA. The correlation between log-transformed circulating adiponectin levels and age, gender, measures of obesity (body mass index, waist circumference, and percent fat mass), and serum lipid levels was assessed. Linear regression was used to explore the association between adiponectin levels and measures of obesity, lipids, and insulin resistance as measured by homeostasis model assessment.ResultsSignificant negative associations were observed between log-adiponectin levels and measures of obesity after adjusting for age and gender. Similarly, log-adiponectin levels were significantly negatively associated with serum triglycerides and insulin resistance but positively associated with high-density lipoprotein-cholesterol and total cholesterol after adjusting for age, gender, and body mass index.ConclusionsCirculating adiponectin is significantly associated with measures of obesity, serum lipids, and insulin resistance in this study of West African populations.
