Abstract BackgroundAfrican neurosurgical practice is faced with numerous challenges. Although there have been improvements in recent years, some problems persist. Research can help identify these problems and propose solutions for the growth of African neurosurgery. In this study, we decided to evaluate the landscape of African research.MethodsPubMed, Embase, and Web of Science were searched from inception to April 24, 2020. Duplicate articles were excluded, and at least two authors reviewed non-duplicate articles on Rayyan. After data had been extracted, they were analyzed to generate descriptive statistics (number of articles and articles per local neurosurgeon). The Kruskal Wallis test and Spearman's correlation were used for bivariate data analyses.ResultsThe authors reviewed 667 articles on neurosurgery in 34 (63%, n=54) African countries. Malawi (4.50), South Africa (3.33), and Benin (2.33) had the highest number of articles per local neurosurgeon (after excluding articles by foreign researchers). Foreign researchers published 1.0 (IQR=2.5) articles per country. Articles were published in World Neurosurgery (120, 18.0%), South African Medical Journal (44, 6.6%), and Journal of Neurosurgery Pediatrics (34, 5.1%). The articles were on pediatric neurosurgery (167, 25.0%) and neurotrauma (129, 19.3%). Also, the majority (411, 61.6%) of studies were cross-sectional.ConclusionAfrican neurosurgeons produce a median of 0.4 articles and publish in well-established journals. Collaboration with foreign researchers significantly increases local research output. In the future, we should assess the impact of this research.

Abstract Background Research is an essential component of Anesthesia, and the contributions of researchers and institutions can be appreciated from the analysis of scholarly outputs. Such analyses help identify major contributors and trends in publication. Little is known about the state of Anesthesia and Critical Care Medicine (A.C.C.M.) research in Africa. We aimed to describe African A.C.C.M. research’s current landscape by determining its productivity per country and point towards possible ideas for improvement. Methods The authors searched PubMed, Embase, Web of Science, and Cumulative Index to Nursing and Allied Health Literature (CINAHL) from inception to May 4, 2020, for articles on or about A.C.C.M. in Africa. Studies were selected based on their titles and abstracts. Rayyan software was later on used for data management in the review selection process. Then, the full-text of eligible articles were screened. Data were extracted, and the number of articles per physician anesthesia providers and provider density were calculated. Kruskal Wallis test and Spearman’s correlation were used, and a P-value < 0.05 was considered statistically significant. Results Of the 4690 articles, only 886 (18.9%) were included in the analysis. The articles were published between 1946 and 2020 in 278 target journals. 55 (6.2%) articles were published in the South African Journal of Surgery, 51 (5.8%) in Anesthesia and Analgesia, and 46 (5.2%) in Anaesthesia. 291 (32.8%) studies were cross-sectional. 195 (22.0%) first authors were from Nigeria, 118 (13.3%) from South Africa, and 88 (9.9%) from the U.S.A. Malawi (1.67), Togo (1.06), and Sierra Leone (1.00) had the highest number of articles per provider. Whereas Ethiopia (580.00), Nigeria (336.21), and Malawi (333.33) had the highest number of articles per provider density. Conclusion We identified the most and least productive African countries in A.C.C.M. research and a low-quality hierarchy of evidence in these publications. Hence, the study’s findings may aid in driving the A.C.C.M. research agenda and capacity building in Africa.

Abstract We tested if peer-reviewed conservation research output has increased in sub-Saharan African countries over the last 30 years in response to increased development. We carried out a bibliometric analysis to identify the number of conservation research papers published by national authors of 41 sub-Saharan African countries during 1987–2017, to provide an index of national conservation research output. We identified country-specific development factors influencing these totals, using general linear modelling. There were positive relationships between conservation research output and population size, GDP, literacy rate, international tourism receipts and population growth rate, and negative relationships with urban population and agricultural land cover, in total explaining 77% of variation. Thirty-eight per cent of countries contributed < 30 conservation research papers (of 12,701) in 30 years. Analysis of trends in primary authorship in a random subsample of 2,374 of these papers showed that primary authorship by sub-Saharan African authors has increased significantly over time but is now at a lower rate than primary authorship for authors from countries outside the country associated with the search term, usually a European or North American country. Overall, 46% of papers had national primary authors, but 67% of these were South African. The results show that conservation research output in sub-Saharan Africa overall is increasing but only significantly in a few countries, and is still dominated by non-national scientists, probably as a result of a lack of socio-economic development.

The Impact

IntroductionCardiovascular disease (CVD) risk factors are increasing in sub-Saharan Africa. The impact of these risk factors on future CVD outcomes and burden is poorly understood. We examined the magnitude of modifiable risk factors, estimated future CVD risk and compared results between three commonly used 10-year CVD risk factor algorithms and their variants in four African countries.MethodsIn the Africa-Wits-INDEPTH partnership for Genomic studies (the AWI-Gen Study), 10 349 randomly sampled individuals aged 40–60 years from six sites participated in a survey, with blood pressure, blood glucose and lipid levels measured. Using these data, 10-year CVD risk estimates using Framingham, Globorisk and WHO-CVD and their office-based variants were generated. Differences in future CVD risk and results by algorithm are described using kappa and coefficients to examine agreement and correlations, respectively.ResultsThe 10-year CVD risk across all participants in all sites varied from 2.6% (95% CI: 1.6% to 4.1%) using the WHO-CVD lab algorithm to 6.5% (95% CI: 3.7% to 11.4%) using the Framingham office algorithm, with substantial differences in risk between sites. The highest risk was in South African settings (in urban Soweto: 8.9% (IQR: 5.3–15.3)). Agreement between algorithms was low to moderate (kappa from 0.03 to 0.55) and correlations ranged between 0.28 and 0.70. Depending on the algorithm used, those at high risk (defined as risk of 10-year CVD event >20%) who were under treatment for a modifiable risk factor ranged from 19.2% to 33.9%, with substantial variation by both sex and site.ConclusionThe African sites in this study are at different stages of an ongoing epidemiological transition as evidenced by both risk factor levels and estimated 10-year CVD risk. There is low correlation and disparate levels of population risk, predicted by different risk algorithms, within sites. Validating existing risk algorithms or designing context-specific 10-year CVD risk algorithms is essential for accurately defining population risk and targeting national policies and individual CVD treatment on the African continent.

Background/Aim. Acne is a common problem in adolescent children with considerable emotional and psychological effects. The aim of this study was to determine the self-reported prevalence of acne and to assess its impact on the quality of life in high school pupils in Serbia. Methods. The cross-sectional study was conducted in May 2011 in two medical high schools in Serbia. Only pupils who gave a written informed consent to participate in the study (n = 440) were asked to fill in two questionnaires: short demographic questionnaire and Cardiff Acne Disability Index (CADI), a disease-specific questionnaire measuring disability induced by acne. Internal consistency (tested by Cronbach?s alpha) and item-total score correlations (Spearman's correlation analysis) were used for reliability analyses. Results. The study population consisted of 440 pupils, 281 from Belgrade and 159 from Uzice. Among them 371 (84.3%) were girls and 69 (15.7%) boys, with similar sex distribution in Belgrade and Uzice. The total mean age of pupils was 16.48 years (SD = 0.55). Out of 440 pupils 228 (51.8%) self-reported their acne. The acne prevalence was significantly higher in pupils from Uzice (73.6%) than in those from Belgrade (39.6%). The overall mean CADI score for the whole sample was 2.87 ? 2.74, with the similar quality of life impairment in adolescents from Belgrade and from Uzice. The mean Cronbach?s alpha was 0.82. Conclusion. This study shows that the quality of life impairment due to acne is mild for the majority of the affected pupils. The Serbian version of the CADI is a reliable, valid, and valuable tool for assessing the impact of acne on the quality of life.

Studies from India and several eastern African countries found that the impact of dairy animal ownership on household nutrition varied greatly, depending on the socio-geographic context. The purpose of this study was to examine the association between livestock ownership and household dietary quality in rural Kolar district, India. We collected data from a household survey in four study villages (n = all 195 households of the four villages) of Kolar district, applying a cross-sectional design. Kendall’s rank correlation coefficient was employed to determine the correlation between milk consumption and other dietary variables. Multivariable logistic regression was used to describe the relationship between dairy animal ownership and household milk consumption. Households owning dairy animals more often had access to irrigation (58.3% vs. 25.2%) and were less often woman-headed (2.4% vs. 22.5%). Household milk consumption was significantly correlated with consumption of vegetable variety, egg, and meat (all p-values < 0.05). After adjusting for multiple confounders, the odds ratio of milk consumption between dairy animal-owning households as compared to other households was 2.11 (95% confidence interval 0.85, 5.45). While dairy animal ownership was found to be associated with improved dietary quality, larger households were in a better position to adopt dairy animals, which, in turn, might contribute to better household nutrition.

The main objective of this paper is to test the influence of Africa’s founding fathers and the impact of British colonial legacy on the political stability of Africa. We relied on a sample of 50 African countries and employed cross-sectional research designs, which covered two separate periods (1960–1989 and 1990–2018). Using logistic regression and OLS estimators and controlling for French colonial legacy, economic development, regime type, ethnic heterogeneity, and ethnic polarization, we found that the founding fathers were conducive to Africa’s political stability between 1960 and 2018. We also found that British colonial legacy had some impact on former British colonies’ stability between 1960 and 2018. In addition, GDP per capita had a significant impact on Africa’s political stability over the two periods.

Background: Simulation-based education (SBE) has been shown to be an effective and reproducible learning tool. SBE is used widely internationally. The current state of SBE in South Africa is unknown. To the best of our knowledge this is the first survey that describes the use and attitudes towards SBE within South Africa. Methods: An online survey tool was distributed by email to: i) the South African Society of Anaesthesiologists (SASA) members; and ii) known simulation education providers in South Africa. The respondents were grouped into anaesthesia and non-anaesthesia participants. Descriptive statistics were used to analyse the data. Ethics approval was obtained: HREC REF 157/2017. Results: The majority of the respondents provide SBE and integrate it into formal teaching programmes. There is a will amongst respondents to grow SBE in South Africa, with it being recognised as a valuable educational tool. The user groups mainly targeted by SBE, were undergraduate students, medical interns, registrars and nurses. Learning objectives targeted include practical skills, medical knowledge, critical thinking and integrated management. Amongst anaesthesia respondents: the tool most commonly used to assess the quality of learner performance during SBE, for summative assessment, was ‘expert opinion’ (33%); the most frequent methods of evaluating SBE quality were participant feedback (42%) and peer evaluation (22%); the impact of SBE was most frequently assessed by informal discussion (42%) and learner feedback (39%). In anaesthesia SBE largely takes place within dedicated simulation facilities on site (47%). Most respondents report access to a range of SBE equipment. The main reported barriers to SBE were: finance, lack of trained educators, lack of equipment and lack of protected time. A limited number of respondents report engaging in SBE research. There is a willingness in both anaesthesia and non-anaesthesia groups (96% and 89% respectively) to collaborate with other centres. Conclusion: To the best of our knowledge this publication provides us with the first cross-sectional survey of SBE in anaesthesia and a selection of non-anaesthetic respondents within South Africa. The majority of respondents indicate that SBE is a valuable education tool. A number of barriers have been identified that limit the growth of SBE within South Africa. It is hoped that with a commitment to ongoing SBE research and evaluation, SBE can be grown in South Africa.

Purpose This paper aims to examine the impact of interest rate liberalization on economic growth and the relevance of corruption in the five selected sub-Saharan African countries. Design/methodology/approach The study used the modified version of Driscoll and Kraay’s model by Hoechle, which solved the effects of cross-sectional dependence and heteroscedasticity. Findings The findings reveal a positive impact of the index on economic growth, and it was found that foreign direct investment (FDI) and credit to private sector by banks (CPSB) all stimulate economic growth. The interaction terms of corruption with FDI and CPSB indicate negative effects that show how corruption erodes the benefits of liberalization. Finally, the paper recommends the pursuit of appropriate policies with the sole aim of eradicating corruption and providing a conducive environment for business. Originality/value The paper developed a composite domestic financial liberalization index to capture the timing and essential dimensions of the reform process. The study investigates the effect of interest rate liberalization on economic growth and the relevance of corruption. Most of the recent and past studies only examined the impact of interest rate reforms on growth without investigating the relevance of corruption.

Literature suggests that performance appraisal (PA) contributes to innovation. However, the absolute and relative importance of PA to innovation, the different aspects of PA which drive innovation, as well as PA as a precursor among other antecedents to innovation, has not been adequately described. The aim of the study is to provide clarity on the drivers of innovation, specifically contextualising the impact of PA within the South African context. This study used a cross-sectional survey design, where only quantitative data was collected from full-time employees across private sector, parastatal, and government organisations. The respondents represented a broad cross-section of South African employees. PA and three other known antecedents to innovation, as well as innovation itself, were measured. It was found that PA (as a single variable) was responsible for 5.7% of the variance in innovation. Items in the PA scale with a clear link to innovation were identified, and thematically integrated. It was further found that, when PA was combined with other antecedents of innovation, leading to 26.6% of the variance in innovation being explained, the role of PA was significant, though mostly secondary. Proactive personality was the most dominant predictor of innovation. The importance and relative importance of PA as an antecedent to innovation in the workplace has thus been established. The outcomes of this study may assist managers and human resource practitioners to focus on appropriate, evidence-based information when attempting to enhance innovation.

Purpose The purpose of this study is to determine the relationship between different dimensions of organizational learning capabilities (OLC) and levels of social innovation in social enterprises. Design/methodology/approach The empirical strategy adopted is a cross-sectional study based on primary survey data. Following a survey of social enterprises in South Africa, statistically analysis is conducted using regression analyses to test the study hypotheses. Findings The findings show that the OLC dimensions of knowledge conversion, risk management, organizational dialogue and participative decision-making all have a significant and positive relationship with social innovation. Research limitations/implications In many emerging economies, the notion of organizational learning appears to have considerable potential relevance, particularly as African countries are moving toward knowledge-based economies. By focusing on OLC, it is anticipated that social enterprises can configure and leverage the different factors in ways that enable them to overcome the constraints of the complex and unpredictable environments and increase their levels of social innovation. Originality/value The paper provides a pioneering empirical investigation into the impact that OLC has on levels of social innovation, in an under-researched emerging market context.
