Purpose of this systematic review was to bring together studies of evidence-based practice among dentists in low- and middle-income countries, where its use has been reported to be limited. The protocol was registered in PROSPERO. Methodology: We searched the evidence (in English only) from medical databases including PubMed, EBSCO, The Cochrane Library, CINAHL, ScienceDirect, HINARI summon, and SCOPUS and Web of Science via Research4Life, grey literature, hand search from relevant articles, and augmented results on Google scholar.Published reports were retrieved from relevant websites and organizations. Studies included those that looked at key factors that facilitate or hinder Evidence Based Dentistry (EBD), as well as outcomes in terms of: knowledge, attitudes and skills of EB practice among dentists; and the methodology used and their relevance in future EBD strategies.Main focus was on dentists, as practitioners and faculty members. Studies on students and non-dental personnel were excluded.Findings:A total of 4568 records were retrieved and five potentially relevant articles were selected after title/abstract screening. Two articles were excluded after full text screening, and therefore Three papers were included in this review. The studies report limited knowledge,unsatisfactory attitude towards EBD and lowpractice of EBD and use of scientific evidence databases. None of the studies reported implementation of EBD nor evaluation thereof. The main barriers that constrained application of EBD ranged from lack of interest to infrastructural limitations. Originality: The current review showed that there is a need to strategised implementation of EBD in this region.

IntroductionBreast and cervical cancers pose a major public health burden globally, with disproportionately high incidence, morbidity and mortality in low- and middle-income countries (LMICs). The majority of women diagnosed with cancer in LMICs present with late-stage disease, the treatment of which is often costlier and less effective. While interventions to improve the timely diagnosis of these cancers are increasingly being implemented in LMICs, there is uncertainty about their role and effectiveness. The aim of this review is to systematically synthesise available evidence on the nature and effectiveness of interventions for improving timely diagnosis of breast and cervical cancers in LMICs.Methods and analysisA comprehensive search of published and relevant grey literature will be conducted. The following electronic databases will be searched: MEDLINE (via PubMed), Cochrane Library, Scopus, CINAHL, Web of Science and the International Clinical Trials Registry Platform (ICTRP). Evidence will be synthesised in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA). Two reviewers will independently screen the search outputs, select studies using predefined inclusion criteria and assess each included study for risk of bias. If sufficient data are available and studies are comparable in terms of interventions and outcomes, a meta-analysis will be conducted. Where studies are not comparable and a meta-analysis is not appropriate, a narrative synthesis of findings will be reported.Ethics and disseminationAs this will be a systematic review of publicly available data, with no primary data collection, it will not require ethical approval. Findings will be disseminated widely through a peer-reviewed publication and forums such as conferences, workshops and community engagement sessions. This review will provide a user-friendly evidence summary for informing further efforts at developing and implementing interventions for addressing delays in breast and cervical cancer diagnosis in LMICs.PROSPERO registration numberCRD42020177232.

Abstract Background Seroprevalence of SARS Cov-2 provides a good indication of the extent of exposure and spread in the population, as well as those likely to benefit from a vaccine candidate. To date, there is no published or ongoing systematic review on the seroprevalence of COVID-19 in Low- and Middle-Income Countries (LMICs). This systematic review and meta-analysis will estimate SARS Cov-2 seroprevalence and the risk factors for SARS Cov-2 infection in LMICs.Methods We will search PubMed, EMBASE, WHO COVID-19 Global research database, Google Scholar, the African Journals Online, LILAC, HINARI, medRxiv, bioRxiv and Cochrane Library for potentially useful studies on seroprevalence of COVID-19 in LMICs from December 2019 to December 2020 without language restriction. Two authors will independently screen all the articles, select studies based on pre-specified eligibility criteria and extract data using a pre-tested data extraction form. Any disagreements will be resolved through discussion between the authors. The pooled seroprevalence of SARS CoV-2 for people from LMICs will be calculated. Random effects model will be used in case of substantial heterogeneity in the included studies, otherwise fixed-effect model will be used. A planned subgroup, sensitivity and meta-regression analyses will be performed. For comparative studies, the analyses will be performed using Review Manager v 5.4; otherwise, STATA 16 will be used. All effect estimates will be presented with their confidence intervals.Discussion The study will explore and systematically review empirical evidence on SARS Cov-2 seroprevalence in LMICs, and to assess the risk factors for SARS Cov-2 infection in Low Middle Income Countries in the context of rolling out vaccines in these countries. Finally, explore risk classifications to help with the rolling out of vaccines in LMICs.Systematic review registration: The protocol for this review has been registered in PROSPERO (CRD422020221548).

Almost two billion people are deficient in key vitamins and minerals, mostly women and children in low- and middle-income countries (LMICs). Deficiencies worsen during pregnancy due to increased energy and nutritional demands, causing adverse outcomes in mother and child, but could be mitigated by interventions like micronutrient supplementation. To our knowledge, this is the first systematic review that aimed to compile evidence from both efficacy and effectiveness trials, evaluating different supplementation interventions on maternal, birth, child health, and developmental outcomes. We evaluated randomized controlled trials and quasi-experimental studies published since 1995 in peer-reviewed and grey literature that assessed the effects of calcium, vitamin A, iron, vitamin D, and zinc supplementation compared to placebo/no treatment; iron-folic (IFA) supplementation compared to folic acid only; multiple micronutrient (MMN) supplementation compared to IFA; and lipid-based nutrient supplementation (LNS) compared to MMN supplementation. Seventy-two studies, which collectively involved 314 papers (451,723 women), were included. Meta-analyses showed improvement in several key birth outcomes, such as preterm birth, small-for-gestational age (SGA) and low birthweight with MMN supplementation, compared to IFA. MMN also improved child outcomes, including diarrhea incidence and retinol concentration, which are findings not previously reported. Across all comparisons, micronutrient supplementation had little to no effect on mortality (maternal, neonatal, perinatal, and infant) outcomes, which is consistent with other systematic reviews. IFA supplementation showed notable improvement in maternal anemia and the reduction in low birthweight, whereas LNS supplementation had no apparent effect on outcomes; further research that compares LNS and MMN supplementation could help understand differences with these commodities. For single micronutrient supplementation, improvements were noted in only a few outcomes, mainly pre-eclampsia/eclampsia (calcium), maternal anemia (iron), preterm births (vitamin D), and maternal serum zinc concentration (zinc). These findings highlight that micronutrient-specific supplementation should be tailored to specific groups or needs for maximum benefit. In addition, they further contribute to the ongoing discourse of choosing antenatal MMN over IFA as the standard of care in LMICs.

Abstract Engagement of youth in agriculture in low- and middle-income countries may offer opportunities to curb underemployment, urban migration, disillusionment of youth and social unrest, as well as to lift individuals and communities from poverty and hunger. Lack of education or skills training has been cited as a challenge to engage youth in the sector. Here we systematically interrogate the literature for the evaluation of skills training programmes for youth in low- and middle-income countries. Sixteen studies—nine quantitative, four qualitative and three mixed methods—from the research and grey literature documented the effects of programmes on outcomes relating to youth engagement, including job creation, income, productivity and entrepreneurship in agriculture. Although we find that skills training programmes report positive effects on our chosen outcomes, like previous systematic reviews we find the topic to chronically lack evaluation. Given the interest that donors and policymakers have in youth engagement in agriculture, our systematic review uncovers a gap in the knowledge of their effectiveness.

IntroductionThere is a severe shortage of specialist mental healthcare providers in low-income and middle-income countries (LMICs) affected by humanitarian crises. In these settings, talking therapies may be delivered by non-specialists, including lay workers with no tertiary education or formal certification in mental health. This systematic review will synthesise the literature on the implementation and effectiveness of talking therapies delivered by lay workers in LMICs affected by humanitarian crises, in order to develop a Theory of Change (ToC).Methods and analysisQualitative, quantitative and mixed-methods studies assessing the implementation or effectiveness of lay-delivered talking therapies for common mental disorders provided to adult survivors of humanitarian crises in LMICs will be eligible for inclusion. Studies set in high-income countries will be excluded. No restrictions will be applied to language or year of publication. Unpublished studies will be excluded. Seven electronic databases will be searched: MEDLINE, Embase, PsycINFO, PsycEXTRA, Global Health, Cochrane Library and ClinicalTrials.gov. Contents pages of three peer-reviewed journals will be hand-searched. Sources of grey literature will include resource directories of two online mental health networks (MHPSS.net and MHInnovation.net) and expert consultation. Forward and backward citation searches of included studies will be performed. Two reviewers will independently screen studies for inclusion, extract data and assess study quality. A narrative synthesis will be conducted, following established guidelines. A ToC map will be amended iteratively to take into account the review results and guide the synthesis.Ethics and disseminationFindings will be presented in a manuscript for publication in a peer-reviewed journal and disseminated through a coordinated communications strategy targeting knowledge generators, enablers and users.PROSPERO registration numberCRD42017058287.

Background: The burden of stroke in low- and middle-income countries (LMICs) is large and increasing, challenging the already stretched health-care services. Aims and Objectives: To determine the quality of existing stroke-care services in LMICs and to highlight indigenous, inexpensive, evidence-based implementable strategies being used in stroke-care. Methods: A detailed literature search was undertaken using PubMed and Google scholar from January 1966 to October 2015 using a range of search terms. Of 921 publications, 373 papers were shortlisted and 31 articles on existing stroke-services were included. Results: We identified efficient models of ambulance transport and pre-notification. Stroke Units (SU) are available in some countries, but are relatively sparse and mostly provided by the private sector. Very few patients were thrombolysed; this could be increased with telemedicine and governmental subsidies. Adherence to secondary preventive drugs is affected by limited availability and affordability, emphasizing the importance of primary prevention. Training of paramedics, care-givers and nurses in post-stroke care is feasible. Conclusion: In this systematic review, we found several reports on evidence-based implementable stroke services in LMICs. Some strategies are economic, feasible and reproducible but remain untested. Data on their outcomes and sustainability is limited. Further research on implementation of locally and regionally adapted stroke-services and cost-effective secondary prevention programs should be a priority.

Abstract Background: Globally, health care workers continue to be infected, fall ill and die at the frontline of the Coronavirus disease 2019 (COVID-19) fight, an indicator of inadequate safety in health facilities. This rapid evidence synthesis aims to highlight the impacts of COVID-19 on healthcare workers in low-and middle-income countries (LMICs) in terms of infections, illnesses and deaths. Methods: A systematic review will be done. Article search will be performed by an experienced librarian in PubMed, MEDLINE Ovid, Google Scholar, COVID-END, Cochrane library and targeted search from other relevant sources. MeSH terms and Boolean operators “AND” and “OR” will be used in the article search. Independent reviewers will screen the retrieved articles using a priori criteria. Data abstraction will be done using an excel based abstraction tool and synthesized using structured narratives and summary of findings tables. Discussion and anticipated use of results: This evidence synthesis seeks to analyze the impact of COVID-19 on the healthcare systems of low- and middle-income countries. Information on healthcare worker infections, illness, and deaths due to COVID-19, will be collated from published research articles. This will help guide decision makers in establishing low- cost high impact interventions to mitigate the effects of COVID-19 in the health work force.Protocol registration: PROSPERO CRD 42020204174

While adoption of the Ponseti method has continued gradually, its use to manage patients with congenital talipes equinovarus (CTEV) has been limited in low- and middle-income countries (LMICs) for a number of reasons including a lack of clinical training on technique and lack of appropriate clinical equipment. There are a frequent number of emerging studies that report on the role of clubfoot training programmes; however, little is known in regard to cumulative benefits. A systematic review was undertaken through Medline, the Cochrane Library and Web of Science for studies analysing clubfoot training programmes. There were no limitations on time, up until the review was commenced on January 2020. The systematic review was registered with PROSPERO as 165657. Ten articles complied with the inclusion criteria and were deemed fit for analysis. Training programmes lasted an average of 2–3 days. There was a reported increase in knowledge of applying the Ponseti method in managing clubfoot by participants (four studies P < 0.05). Skill retention was examined by multiple choice (MCQ) examination style questions before and after the training programme in two studies; both showed an improvement (MCQ answers improved from 59% to 73%). All studies showed an improvement in participants' self-reported understanding of the Ponseti method and confidence in its use in future practice ( P < 0.05). There were improved benefits of knowledge and clinical application of the Ponseti method by participants in the programmes in all studies examined. However, there was a significant lack of follow-up and exploration of long-term effects of these programmes. Implementing training programmes based on perceived benefits rather than actual long-term benefits may have a negative impact on healthcare delivery and patient management in LMICs.
