RESUMEN

With advances in clinical knowledge and changing norms for health services delivery, lifelong learning is essential for practitioners of sexual and reproductive health. Clinical topics should be complemented by various items, such as communications and management, to optimise the provision of care. Aiming to update knowledge, improve skills and enhance competence, professional development can take the form of diverse modalities ranging from the reading of professional journals through attendance at meetings to formal participation in schemes organised by licensing authorities. Already mandatory in numerous countries in Africa, continuing professional development is assuming more importance for medical, nursing, and midwifery practitioners.


Avec les progrès des connaissances cliniques et l'évolution des normes en matière de prestation de services de santé, l'apprentissage tout au long de la vie est essentiel pour les praticiens de la santé sexuelle et reproductive. Les sujets cliniques doivent être complétés par divers éléments, tels que la communication et la gestion, pour optimiser la prestation des soins. Visant à mettre à jour les connaissances, à améliorer les compétences et à améliorer les compétences, le développement professionnel peut prendre la forme de diverses modalités allant de la lecture de revues professionnelles à la participation à des réunions en passant par la participation formelle à des programmes organisés par les autorités chargées des licences. Déjà obligatoire dans de nombreux pays d'Afrique, la formation professionnelle continue prend de plus en plus d'importance pour les praticiens médicaux, infirmiers et obstétricaux.

RESUMEN

ABSTRACTScientific evidence on the safety and efficacy of pharmaceutical drugs, substances and herbal medicines is important in medical advertising and promotion. Following guidelines for conducting a scoping review, we systematically searched PubMed, SCOPUS and Web of Science to identify in peer reviewed articles medications that were promoted and used widely in Africa during the COVID-19 pandemic. We also searched for information about how safety concerns about untested/or not properly tested drugs were communicated to the public during the pandemic. Of the 2043 articles identified, 41 papers were eligible for inclusion. Most studies were clinical trials (n = 11), systematic reviews (n = 9), quantitative studies (n = 9) the rest were qualitative studies, reviews and reports. We found that following global trends, several drugs, traditional and herbal treatments were used and repurposed for the treatment of respiratory symptoms of COVID-19 in Africa. The results highlighted the value of some herbal medicines for treatment during the COVID-19 pandemic, as well as the risks posed by the unregulated sharing of advice and recommendations on treatments in Africa, and globally.

RESUMEN

Surgical access remains a pressing public health concern in African nations, with a substantial portion of the population facing challenges in obtaining safe, timely, and affordable surgical care. This paper delves into the impact of health insurance schemes on surgical accessibility in Africa, exploring the barriers, challenges, and future directions. It highlights how high out-of-pocket costs, reliance on traditional healing practices, and inadequate surgical infrastructure hinder surgical utilization. Financing mechanisms often need to be more effective, and health insurance programs face resistance within the informal sector. Additionally, coverage of the poor remains a fundamental challenge, with geographical and accessibility barriers compounding the issue. Government policies, often marked by inconsistency and insufficient allocation of resources, create further obstacles. However, strategic purchasing and fund integration offer avenues for improving the efficiency of health insurance programs. The paper concludes by offering policy recommendations, emphasizing the importance of inclusive policies, streamlined financing mechanisms, coverage expansion, and enhanced strategic purchasing to bridge the surgical access gap in Africa. Decoupling entitlement from the payment of contributions, broadening the scope of coverage for outpatient medicines and related expenses, and enhancing safeguards against overall costs and charges, especially for individuals with lower incomes. Ultimately, by addressing these challenges and harnessing the potential of health insurance schemes, the continent can move closer to achieving universal surgical care and improving the well-being of its people.

RESUMEN

There is a growing political interest in health reforms in Africa, and many countries are choosing national health insurance as their main financing mechanism for universal health coverage. Although vaccination is an essential health service that can influence progress toward universal health coverage, it is not often prioritized by these national health insurance systems. This paper highlights the potential gains of integrating vaccination into the package of health services that is provided through national health insurance and recommends practical policy actions that can enable countries to harness these benefits at population level.

RESUMEN

INTRODUCTION: Africa has one of the highest burdens of cervical cancer in the world. The unacceptably high incidence and mortality rates could be reduced through implementing a comprehensive approach to its prevention and control that includes screening, which however, is low in most low-and-middle-income countries. Hence, this systematic review aims at exploring factors that prevent women from utilising cervical cancer screening services in the region. METHODS: A mixed method systematic review was conducted. A search was performed on PubMed (Medline), EMBASE, CINAHL (EBSCOHOST) and Scopus databases for articles published until May 2019 without time, language or study design limits. Two reviewers critically appraised the included studies independently using the standard quality assessment criteria for evaluating primary research papers. Results of the quantitative and mixed methods studies were transformed into qualitative data and synthesised using thematic analysis. RESULTS: From a potential 2 365 studies, 24 from 11 countries met the eligibility criteria and were selected; eight qualitative, 13 quantitative, and three that used the mixed-method approach. The primary barriers were identified as poor access to screening services, lack of awareness and knowledge on cervical cancer and screening, and socio-cultural influences. Service providers perceived lack of skills, screening equipment and supplies, and staff shortages as the major barriers to the provision of screening services. CONCLUSION: Barriers to cervical cancer screening in Africa are multifaceted and require a holistic approach that will address them concurrently at the health system, individual, interpersonal, community and structural levels. Political will complimented by stakeholder involvement is required in the development and implementation of strategies that will ensure acceptability, availability, accessibility, and affordability of screening to minimise barriers in accessing the service.

RESUMEN

BACKGROUND: cute kidney injury(AKI) is a rapid loss of the kidney's excretory function, resulting in an accumulation of end products of nitrogen metabolism. The causes of AKI in HIV-positive patients are not well investigated, but it may be associated with antiretroviral drug side effects and HIV itself. Even though there were studies that reported the prevalence of AKI among HIV-positive patients in Africa, their findings were inconsistent across the studies. METHODS: We searched on PubMed, Embas, Ebsco, OVID, Cochrane Library, and other supplementary search engines, including Google and Google Scholar. Articles published upto July 2023 were included in this review study. The quality of the study was assessed using the Newcastle-Ottawa Scale for cross-sectional, case-control, and cohort studies. The data were extracted using a Microsoft Excel spreadsheet and exported to Stata version 14 for analysis. A random effect meta-analysis model was used to estimate the pooled prevalence of AKI among HIV-positive patients. Heterogeneity was evaluated using Cochrane Q statistics and I squared (I2). Furthermore, the graphic asymmetric test of the funnel plot and/or Egger's tests were computed to detect publication bias. Sensitivity analysis was computed to see the effect of a single study on the summary effects. To treat the publication bias, a trim and fill analysis was carried out. The protocol of this review has been registered in an international database, the Prospective Register of Systematic Reviews (PROSPERO),with reference number CRD42023446078. RESULTS: A total of twenty-four original articles comprising 7913HIV-positive patients were included in the study. The pooled prevalence of AKI among HI-positive patients was found to be 23.35% (95% CI: 18.14-28.56%, I2 = 97.7%, p-value <0.001). Low hemoglobin (Hgb <8mg/dl) was found to be the determinant factor for AKI among HIV-positive patients (AOR = 2.4; 95% CI:1.69-3.4, I2 = 0.0%, p-value = 0.40). In meta-regression analysis, sample size was the possible source of variation among the included studies (AOR = 3.11, 95%CI: 2.399-3.83). CONCLUSIONS: The pooled prevalence of AKI among HIV-positive patients was high. HIV-positive patients with low hemoglobin levels are at risk of developing AKI. Hence, regular monitoring of kidney function tests is needed to prevent or delay the risk of AKI among HIV-positive patients. Healthcare workers should provide an integrated healthcare service to HIV-positive patients on the prevention, treatment, and reduction of the progression of AKI to advanced stages and complications.

RESUMEN

Sickle cell disease (SCD), a distinctive and often overlooked illness in the 21st century, is a congenital blood disorder characterized by considerable phenotypic diversity. It comprises a group of disorders, with sickle cell anemia (SCA) being the most prevalent and serious genotype. Although there have been some systematic reviews of global data, worldwide statistics regarding SCD prevalence, morbidity, and mortality remain scarce. In developed countries with a lower number of sickle cell patients, cutting-edge technologies have led to the development of new treatments. However, in developing settings where sickle cell disease (SCD) is more prevalent, medical management, rather than a cure, still relies on the use of hydroxyurea, blood transfusions, and analgesics. This is a disease that affects red blood cells, consequently affecting most organs in diverse manners. We discuss its etiology and the advent of new technologies, but the aim of this study is to understand the various types of nutrition-related studies involving individuals suffering from SCD, particularly in Africa. The interplay of the environment, food, gut microbiota, along with their respective genomes collectively known as the gut microbiome, and host metabolism is responsible for mediating host metabolic phenotypes and modulating gut microbiota. In addition, it serves the purpose of providing essential nutrients. Moreover, it engages in direct interactions with host homeostasis and the immune system, as well as indirect interactions via metabolites. Nutrition interventions and nutritional care are mechanisms for addressing increased nutrient expenditures and are important aspects of supportive management for patients with SCD. Underprivileged areas in Sub-Saharan Africa should be accompanied by efforts to define and promote of the nutritional aspects of SCD. Their importance is key to maintaining well-being and quality of life, especially because new technologies and products remain limited, while the use of native medicinal plant resources is acknowledged.

RESUMEN

There have been few reports from Africa on the use and health effects of emollient therapy for newborn infants. We aimed to describe neonatal skin care practices in Africa, and to illuminate opportunities to introduce evidence-based interventions to improve these practices. We conducted a scoping review of the quantitative and qualitative published peer-reviewed and grey literature in English on emollient use in Africa. Outcomes of interest included neonatal skin care practices, with a focus on the application of oils and other products to infant skin, including in association with bathing and massage. We screened 5257 articles and summarised findings from 23 studies-13 qualitative, nine quantitative and one mixed methods-that met our study criteria. Seven studies reported the use of emollients for perceived benefits, including thermal care, treatment for illness, promotion of growth and development, infection reduction, skin condition improvement, spirituality and lubrication to aid massage. Four studies reported the quantitative health impact of skin care product applications, including improvements in skin condition, neurodevelopment and bone growth, as well as a reduction in nosocomial infections. This review highlights opportunities for skin care intervention and future research on neonatal skin care practices in Africa.

RESUMEN

Lippia javanica is a typical indigenous plant species mostly found in the higher elevation or mountainous regions in southern, central, and eastern Africa. The ongoing utilization of the species for ethnobotanical applications and traditional uses, coupled with the changing climate, increases the risk of a potential reduction in its geographic distribution range in the region. Herein, we utilized the MaxEnt species distribution modelling to build the L. javanica distribution models in tropical and subtropical African regions for current and future climates. The MaxEnt models were calibrated and fitted using 286 occurrence records and six environmental variables. Temperatures, including temperature seasonality [Bio 4] and the maximum temperature of the warmest month [Bio 5], were observed to be the most significant determinants of L. javanica's distribution. The current projected range for L. javanica was estimated to be 2,118,457 km2. Future model predictions indicated that L. javanica may increase its geographic distribution in western areas of the continent and regions around the equator; however, much of the geographic range in southern Africa may shift southwards, causing the species to lose portions of the northern limits of the habitat range. These current findings can help increase the conservation of L. javanica and other species and combat localized species loss induced by climate change and human pressure. We also emphasize the importance of more investigations and enhanced surveillance of traditionally used plant species in regions that are acutely susceptible to climate change.

RESUMEN

Root and tuber crop breeding is at the front and center of CIP's science program, which seeks to develop and disseminate sustainable agri-food technologies, information and practices to serve objectives including poverty alleviation, income generation, food security and the sustainable use of natural resources. CIP was established in 1971 in Peru, which is part of potato's center of origin and diversity, with an initial mandate on potato and expanding to include sweetpotato in 1986. Potato and sweetpotato are among the top 10 most consumed food staples globally and provide some of the most affordable sources of energy and vital nutrients. Sweetpotato plays a key role in securing food for many households in Africa and South Asia, while potato is important worldwide. Both crops grow in a range of conditions with relatively few inputs and simple agronomic techniques. Potato is adapted to the cooler environments, while sweetpotato grows well in hot climates, and hence, the two crops complement each other. Germplasm enhancement (pre-breeding), the development of new varieties and building capacity for breeding and variety testing in changing climates with emphasis on adaptation, resistance, nutritional quality and resource-use efficiency are CIP's central activities with significant benefits to the poor. Investments in potato and sweetpotato breeding and allied disciplines at CIP have resulted in the release of many varieties some of which have had documented impact in the release countries. Partnership with diverse types of organizations has been key to the centers way of working toward improving livelihoods through crop production in the global South.

RESUMEN

BACKGROUND: In 2015, the World Health Organization recommended that all people living with HIV begin antiretroviral treatment (ART) regardless of immune status, a policy known as 'Treat-All to end AIDS', commonly referred to as Treat-All. Almost all low- and middle-income countries adopted this policy by 2019. This study describes how linkage to treatment of newly diagnosed persons changed between 2015 and 2018 and how complementary policies may have similarly increased linkage for 13 African countries. These countries adopted and implemented Treat-All policies between 2015 and 2018 and were supported by the U.S. Government's President's Emergency Plan for AIDS Relief (PEPFAR). The focuses of this research were to understand 1) linkage rates to ART initiation before and after the adoption of Treat-All in each country; 2) how Treat-All implementation differed across these countries; and 3) whether complementary policies (including same-day treatment initiation, task-shifting, reduced ART visits, and reduced ART pickups) implemented around the same time may have increased ART linkage. METHODS: HIV testing and treatment data were collected by PEPFAR country programs in 13 African countries from 2015 to 2018. These countries were chosen based on the completeness of policy data and availability of program data during the study period. Program data were used to calculate proxy linkage rates. These rates were compared relative to the Treat All adoption period and the adoption of complementary policies. RESULTS: The 13 countries experienced an average increase in ART linkage of 29.3% over the entire study period. In examining individual countries, all but two showed increases in linkage to treatment immediately after Treat All adoption. Across all countries, those that had adopted four or more complementary policies showed an average increased linkage of 39.8% compared to 13.9% in countries with fewer than four complementary policies. CONCLUSIONS: Eleven of 13 country programs examined in this study demonstrated an increase in ART linkage after Treat-All policy adoption. Increases in linkage were associated with complementary policies. When exploring new public health policies, policymakers may consider which complementary policies might also help achieve the desired outcome of the public health policy.

RESUMEN

BACKGROUND: Simulating the cardiac function requires the numerical solution of multi-physics and multi-scale mathematical models. This underscores the need for streamlined, accurate, and high-performance computational tools. Despite the dedicated endeavors of various research teams, comprehensive and user-friendly software programs for cardiac simulations, capable of accurately replicating both normal and pathological conditions, are still in the process of achieving full maturity within the scientific community. RESULTS: This work introduces [Formula: see text]-ep, a publicly available software for numerical simulations of the electrophysiology activity of the cardiac muscle, under both normal and pathological conditions. [Formula: see text]-ep employs the monodomain equation to model the heart's electrical activity. It incorporates both phenomenological and second-generation ionic models. These models are discretized using the Finite Element method on tetrahedral or hexahedral meshes. Additionally, [Formula: see text]-ep integrates the generation of myocardial fibers based on Laplace-Dirichlet Rule-Based Methods, previously released in Africa et al., 2023, within [Formula: see text]-fiber. As an alternative, users can also choose to import myofibers from a file. This paper provides a concise overview of the mathematical models and numerical methods underlying [Formula: see text]-ep, along with comprehensive implementation details and instructions for users. [Formula: see text]-ep features exceptional parallel speedup, scaling efficiently when using up to thousands of cores, and its implementation has been verified against an established benchmark problem for computational electrophysiology. We showcase the key features of [Formula: see text]-ep through various idealized and realistic simulations conducted in both normal and pathological scenarios. Furthermore, the software offers a user-friendly and flexible interface, simplifying the setup of simulations using self-documenting parameter files. CONCLUSIONS: [Formula: see text]-ep provides easy access to cardiac electrophysiology simulations for a wide user community. It offers a computational tool that integrates models and accurate methods for simulating cardiac electrophysiology within a high-performance framework, while maintaining a user-friendly interface. [Formula: see text]-ep represents a valuable tool for conducting in silico patient-specific simulations.

RESUMEN

INTRODUCTION: Ultrasound scan is one of the essential assessments that is crucial in the early identification of health risks during antenatal care. Its accessibility to women in low-and middle-income countries remains a serious challenge because ultrasound scans are not within the scope of practice for midwives. However, task shifting and extension of scope of practice aim to train midwives to assess pregnant women through an ultrasound scan. This paper aims to report the findings of a scoping review on the training of midwives to perform obstetric ultrasound scans in Africa. METHODS: The 6-step iterative framework for scoping reviews by Arksey and O'Malley was used to determine the extent of qualitative and quantitative evidence available on the training of midwives on obstetric ultrasound scans, which includes specifying the research question, identifying relevant studies, selecting studies, extracting and charting data, collating, summarising, and synthesising and reporting findings. RESULTS: A total of 12 articles from eight African countries were included in this scoping review. Three main themes and 13 sub-themes emerged and they are: obstetric ultrasound scan training, challenges experienced by midwives from task shifting and extension of scope of practice regarding obstetric ultrasound scan, and the value of task shifting and extension of scope of practice regarding obstetric ultrasound scan to midwives. DISCUSSION: Despite the available evidence that the training of midwives on obstetric ultrasound scans is essential to ensure the accessibility of quality antenatal health services, the training of midwives on obstetric ultrasound scans in some African countries remains a serious challenge. It is evident from this scoping review results that there is a need for African countries to incorporate obstetric ultrasound scans as part of the scope of practice of midwives. Task shifting necessitates prioritising the training of midwives on the use of obstetric ultrasound scans as one of the steps towards the achievement of the United Nations Sustainable Development Goal number 3 targets by 2030.

RESUMEN

The 2022 Monkeypox virus, an evolved DNA strain originating in Africa, exhibits heightened human-to-human transmissibility and potential animal transmission. Its host remains unidentified. While its initial slow transmission rate restrained global impact, 2022 saw a surge in cases, causing widespread concern in over 103 countries by September. This virus's distinctive human-to-human transmission marks a crucial shift, demanding a prompt revaluation of containment strategies. However, the host source for this shift requires urgent research attention. Regrettably, no universal preventive or curative methods have emerged for this evolved virus. Repurposed from smallpox vaccines, only some vaccinations offer a partial defense. Solely one therapeutic drug is available. The article's essence is to provide a comprehensive grasp of the virus's epidemiology, morphology, immune invasion mechanisms, and existing preventive and treatment measures. This knowledge equips researchers to devise strategies against its spread and potential public health implications.

RESUMEN

BACKGROUND: There has been a notable rise in the number of African nurses and midwives migrating to high-income countries despite varying policies and restrictions to promote retention. The need to comprehensively evaluate existing policies addressing the exodus is crucial to future policy formulation and steps in addressing drivers of nurses and midwives brain drain in Africa. AIM: To explore the existence of migration policies that address the drivers of nurse and midwives' migration outside Africa and determine the characteristics and implementation of these policies. METHODS: The review would be guided by the JBI methodology for systematic reviews of text and non-research evidence. Databases including CINAHL, PubMed, Academic Search Complete via Ebscohost and ISI Web of Science will be searched using a PICOS selection criteria framework. Grey literature would be gathered from Google Scholar, government and organisational websites. Two independent reviewers would be involved in searching, study selection, data extraction and data analysis. A third reviewer would provide an arbitrary judgement during conflicts when disagreements persist after discussion. A meta-synthesis would be used to identify and report emerging themes in the literature. ETHICS AND DISSEMINATION: The study does not require ethical approval. The findings would be published in peer-review journals and presented at research conferences. PROSPERO REGISTRATION NUMBER: CRD42023395013.

RESUMEN

Despite the fact that there are many studies related to the adaptogenic and pro-healthy activities of plant-based compounds, there are some adaptogenic plants whose activities are not fully known, especially those coming from the wild regions of Asia, Africa, and South America. The aim of these studies was to examine the contents of non-nutritional compounds, such as polyphenols, flavonoids, and phenolic acids in ten adaptogenic species (Astragalus membranaceus (AM), Uncaria rhynchophylla (UR), Polygonum multiflorum (PM), Angelica sinensis (AS), Andrographis paniculatea (AP), Tinospora cordifolia (TC), Uncaria tomentosa (UT), Pfaffia paniculate (PP), Sutherlandia frutescens (SF), and Rhaponticum carthamoides (RC)). Considering biological activity, their antioxidant (DPPH, ABTS, FRAP, and ferrous-ion-chelating ability assays), anti-acetylcholinesterase, anti-hyaluronidase, and anti-tyrosinase activities were evaluated. The richest in polyphenols, flavonoids, and phenolic acids was UR (327.78 mg GAE/g, 230.13 mg QE/g, and 81.03 mg CA/g, respectively). The highest inhibitions of acetylcholinesterase, hyaluronidase, and tyrosinase were observed for TC, UR, and PM, respectively. In the case of antioxidant properties, extract from PM appeared to most strongly reduce DPPH, extract from UR inhibited ABTS, and extract from SF showed the best chelating properties. It should be noted that a particularly interesting plant was Ulcaria rhynchophylla. The results mean that there were compounds in UR with broad biological activities, and this species should be explored in more detail. Additionally, our results justify the traditional use of these species in the nutripharmacological or ethnopharmacological care systems of different regions.

RESUMEN

Management of COVID-19 in Africa is challenging due to limited resources, including the high cost of vaccines, diagnostics, medical devices and routine pharmaceuticals. These challenges, in addition to wide acceptability, have resulted in increased use of herbal medicines based on African traditional medicines (ATMs) by patients in Africa. This is in spite of the often-significant gaps in evidence regarding these traditional medicines as to their efficacy and safety for COVID-19. African scientists, with some support from their governments, and guidance from WHO and other bodies, are addressing this evidence gap, developing and testing herbal medicines based on ATMs to manage mild-to-moderate cases of COVID-19. Such efforts need further support to meet public health needs.

RESUMEN

BACKGROUND: Globally, countries are taking actions to ensure that their population have improved access to people-centred and integrated health services. Attaining this requires improved access to health workers at all levels of health service delivery and equitably distributed by geographical location. Due to the persistent health worker shortages, countries have resorted to implementing task shifting and task sharing in various settings to optimally utilize existing health workers to improve access to health services. There are deliberations on the need for an implementation framework to guide the adoption and operationalization of task shifting and task sharing as a key strategy for optimally utilizing the existing health workforce towards the achievement of UHC. The objective of this study was to develop an implementation framework for task shifting and task sharing for policy and practice in Africa. METHODS: A sequential multimethod research design supported by scoping reviews, and qualitative descriptive study was employed in this study. The evidence generated was synthesized into an implementation framework that was evaluated for applicability in Africa by 36 subject matter experts. RESULTS: The implementation framework for task shifting and task sharing has three core components - context, implementation strategies and intended change. The implementation strategies comprise of iterative actions in the development, translation, and sustainment phases that to achieve an intended change. The implementation strategies in the framework include mapping and engagement of stakeholders, generating evidence, development, implementation and review of a road map (or action plan) and national and/or sub-national policies and strategies, education of health workers using manuals, job aids, curriculum and clinical guidelines, and monitoring, evaluation, reviews and learning. CONCLUSION: The implementation framework for task shifting and task sharing in Africa serves as a guide on actions needed to achieve national, regional and global goals based on contextual evidence. The framework illustrates the rationale and the role of a combination of factors (enablers and barriers) in influencing the implementation of task shifting and task sharing in Africa.

RESUMEN

The crucial role of the gut microbiome in various diseases has led to increased interest in interventions and therapeutics targeting the human microbiome. Accordingly, the current scoping review analyzed the diseases and interventions involved in gut microbiome research in Africa. The electronic databases of PubMed, Google Scholar, and Scopus were searched from inception to October 2021. This study identified 48 studies involving 7073 study participants. Of the 48 studies, 20 (42%) used interventions to modulate gut microbiota, whereas the remaining 28 (58%) did not. Out of the total African countries, only 13% were involved in intervention-based gut microbiome research, whereas a larger proportion of 67% were not involved in any gut microbiome research. The interventions used in gut microbiome research in Africa include supplements, natural products, educational approaches, associated pathogens, albendazole, fresh daily yogurt, iron-containing lipid-based nutrient supplements, fecal microbiota transplant, and prophylactic cotrimoxazole. This scoping review highlights the current state of gut microbiome research in Africa. The findings of this review can inform the design of future studies and interventions aimed at improving gut health in African populations.
