The Neurosurgical Research Progress of 98 Low- and Low- to Middle-Income Countries from 1928 to 2024

ObjectiveThe aim of the present study was to analyze the trends of neurosurgical research in low and lower-middle-income countries (LLMICs). MethodsThe data was retrieved from Scopus (one of the largest databases) and 82 neurosurgical journals were analyzed. ResultsInitially the global research scholarly output (n=195658) was explored and later papers originating solely from LLMICs, without international collaboration with advance countries (n=8408) were analyzed. The per decade number of publications (from 1920 to May 2024), top ten authors, universities, countries and sources of all (global) countries and 98 LLMICs is provided. 80 countries have published less than 50 papers. Even more striking, 68, 55, 38 and 36 LLMICs countries have produced less than 20, 10, 5 and 3 papers, respectively. The keywords analysis was performed to present the main focus of 8408 publications. The top 1000 most cited documents were also identified, and later relevant scientometrics details were provided. The top countries dynamic and most prolific authors (on the basis of number of publications, total citations, h-index, g-index, and m-index) in the top 1000 cited documents (from LLMICs) are highlighted. DiscussionThe findings suggest that neurosurgical research in LLMICs is low, which could be attributed to several factors including limited funding, inadequate infrastructure, and insufficient training opportunities.

Key barriers to the provision and utilization of maternal health services in low-and lower-middle-income countries; a scoping review

BackgroundThe preservation and promotion of maternal health (MH) emerge as vital global health objectives. Despite the considerable emphasis on MH, there are still serious challenges to equitable access to MH services in many countries. This review aimed to determine key barriers to the provision and utilization of MH services in low- and lower-middle-income countries (LLMICs).MethodsIn this scoping review, we comprehensively searched four online databases from January 2000 to September 2022. In this study, the approach proposed by Arksey and O’Malley was used to perform the review. Consequently, 117 studies were selected for final analysis. To determine eligibility, three criteria of scoping reviews (population, concept, and context) were assessed alongside the fulfillment of the STROBE and CASP checklist criteria. To synthesize and analyze the extracted data we used the qualitative content analysis method.ResultsThe main challenges in the utilization of MH services in LLMICs are explained under four main themes including, knowledge barriers, barriers related to beliefs, attitudes and preferences, access barriers, and barriers related to family structure and power. Furthermore, the main barriers to the provision of MH services in these countries have been categorized into three main themes including, resource, equipment, and capital constraints, human resource barriers, and process defects in the provision of services.ConclusionsThe evidence from this study suggests that many of the barriers to the provision and utilization of MH services in LLMICs are interrelated. Therefore, in the first step, it is necessary to prioritize these factors by determining their relative importance according to the specific conditions of each country. Consequently, comprehensive policies should be developed using system modeling approaches.

Characteristics and outcomes of patients admitted to intensive care units in Uganda: a descriptive nationwide multicentre prospective study

Intensive care unit (ICU) mortality rates have decreased over time. However, in low-and lower-middle income countries (LMICs), there remains an excess ICU mortality with limited understanding of patient characteristics, treatments, and outcomes from small single centre studies. We aimed therefore, to describe the characteristics, therapies and outcomes of patients admitted to all intensive care units in Uganda. A nationwide prospective observational study including all patients admitted Uganda’s ICUs with available daily charts was conducted from 8th January 2018 to 1st April 2018. Socio-demographics and clinical characteristics including worst vital signs in the first 24 h of admission were recorded with calculation of the National Early Warning Score (NEWS-2) and quick Sequential Organ Function Assessment (qSOFA) score. ICU interventions were recorded during the ICU stay and patients were followed up to 28 days in ICU. The primary outcome was 28 day ICU mortality. Three-hundred fifty-one patients were analysed with mean age 39 (24.1) years, 205 (58.4%) males with 197 (56%) surgical admissions. The commonest indication for ICU admission was postoperative care (42.9%), 214 (61%) had at least one comorbidity, with hypertension 104 (48.6%) most prevalent and 35 (10%) HIV positive. The 28 day ICU mortality was 90/351 (25.6%) with a median ICU stay of 3 (1–7) days. The highest probability of death occurred during the first 10 days with more non-survivors receiving mechanical ventilation (80% vs 34%; p < 0.001), sedation/paralysis (70% vs 50%; p < 0.001), inotropic/vasopressor support (56.7% vs 22.2%; p < 0.001) and renal replacement therapy (14.4% vs 4.2%; p < 0.001). Independent predictors of ICU mortality included mechanical ventilation (HR 3.34, 95% CI 1.48–7.52), sedation/paralysis (HR 2.68, 95% CI 1.39–5.16), inotropes/vasopressor (HR 3.17,95% CI 1.89–5.29) and an HIV positive status (HR 2.28, 95% CI 1.14–4.56). This study provides a comprehensive description of ICU patient characteristics, treatment patterns, and outcomes in Uganda. It not only adds to the global body of knowledge on ICU care in resource-limited settings but also serves as a foundation for future research and policy initiatives aimed at optimizing ICU care in Sub-Saharan Africa.

Acute myocardial infarction complicated by cardiogenic shock in Ukraine: multicentre registry analysis 2021-2022.

Data on the results and management strategies in patients with acute myocardial infarction complicated by cardiogenic shock (AMI-CS) in the Low and Lower-Middle Income Countries (LLMICs) are limited. This lack of understanding of the situation partially hinders the development of effective cardiogenic shock treatment programs in this part of the world. The Ukrainian Multicentre Cardiogenic Shock Registry was analyzed, covering patient data from 2021 to 2022 in 6 major Ukrainian reperfusion centres from different parts of the country. Analysis was focusing on outcomes, therapeutic modalities and mortality predictors in AMI-CS patients. We analyzed data from 221 consecutive patients with CS from 6 hospitals across Ukraine. The causes of CS were ST-elevated myocardial infarction (85.1%), non-ST-elevated myocardial infarction (5.9%), decompensated chronic heart failure (7.7%) and arrhythmia (1.3%), with a total in-hospital mortality rate for CS of 57.1%. The prevalence of CS was 6.3% of all AMI with reperfusion rate of 90.5% for AMI-CS. In 23.5% of cases, CS developed in the hospital after admission. Mechanical circulatory support (MCS) utilization was 19.9% using intra-aortic balloon pump alone. Left main stem occlusion, reperfusion deterioration, Charlson Comorbidity Index >4, and cardiac arrest were found to be independent predictors for hospital mortality in AMI-СS. Despite the wide adoption of primary percutaneous coronary intervention as the main reperfusion strategy for AMI, СS remains a significant problem in LLMICs, associated with high in-hospital mortality. There is an unmet need for the development and implementation of a nationwide protocol for CS management and the creation of reference CS centers based on the country-wide reperfusion network, equipped with modern technologies for MCS.

Decentralization and Integration of Advanced Cardiac Care for the World's Poorest Billion Through the PEN-Plus Strategy for Severe Chronic Non-Communicable Disease.

Rheumatic and congenital heart disease, cardiomyopathies, and hypertensive heart disease are major causes of suffering and death in low- and lower middle-income countries (LLMICs), where the world's poorest billion people reside. Advanced cardiac care in these counties is still predominantly provided by specialists at urban tertiary centers, and is largely inaccessible to the rural poor. This situation is due to critical shortages in diagnostics, medications, and trained healthcare workers. The Package of Essential NCD Interventions - Plus (PEN-Plus) is an integrated care model for severe chronic noncommunicable diseases (NCDs) that aims to decentralize services and increase access. PEN-Plus strategies are being initiated by a growing number of LLMICs. We describe how PEN-Plus addresses the need for advanced cardiac care and discuss how a global group of cardiac organizations are working through the PEN-Plus Cardiac expert group to promote a shared operational strategy for management of severe cardiac disease in high-poverty settings.

Critical care delivery across health care systems in low-income and low-middle-income country settings: A systematic review.

Prior research has demonstrated that low- and low-middle-income countries (LLMICs) bear a higher burden of critical illness and have a higher rate of mortality from critical illness than high-income countries (HICs). There is a pressing need for improved critical care delivery in LLMICs to reduce this inequity. This systematic review aimed to characterise the range of critical care interventions and services delivered within LLMIC health care systems as reported in the literature. A search strategy using terms related to critical care in LLMICs was implemented in multiple databases. We included English language articles with human subjects describing at least one critical care intervention or service in an LLMIC setting published between 1 January 2008 and 1 January 2020. A total of 1620 studies met the inclusion criteria. Among the included studies, 45% of studies reported on pediatric patients, 43% on adults, 23% on infants, 8.9% on geriatric patients and 4.2% on maternal patients. Most of the care described (94%) was delivered in-hospital, with the remainder (6.2%) taking place in out-of-hospital care settings. Overall, 49% of critical care described was delivered outside of a designated intensive care unit. Specialist physicians delivered critical care in 60% of the included studies. Additional critical care was delivered by general physicians (40%), as well as specialist physician trainees (22%), pharmacists (16%), advanced nursing or midlevel practitioners (8.9%), ambulance providers (3.3%) and respiratory therapists (3.1%). This review represents a comprehensive synthesis of critical care delivery in LLMIC settings. Approximately 50% of critical care interventions and services were delivered outside of a designated intensive care unit. Specialist physicians were the most common health care professionals involved in care delivery in the included studies, however generalist physicians were commonly reported to provide critical care interventions and services. This study additionally characterised the quality of the published evidence guiding critical care practice in LLMICs, demonstrating a paucity of interventional and cost-effectiveness studies. Future research is needed to understand better how to optimise critical care interventions, services, care delivery and costs in these settings. PROSPERO CRD42019146802.

Systems thinking based approaches to engage with health inequities shaping Antimicrobial Resistance in low and lower-middle-income countries

This paper argues for ‘systems thinking’ as a conceptual framework to address antimicrobial resistance, especially focusing on the context of low and lower middle-income countries (LLMICs), which are plagued with health inequities that magnify the AMR threat. Systems thinking provides two avenues to enhance these mitigation efforts: i) it helps go beyond a purely biomedical approach to incorporate considerations of the social and informational; ii) particularly relevant as is it helps to understand the role of health inequities in shaping AMR related prevention and care processes.

Excess mortality in low-and lower-middle-income countries: A systematic review and meta-analysis

Abstract Background The COVID-19 pandemic caused a massive death toll, but its effect on mortality remains uncertain in low- and lower-middle-income countries (LLMICs). This review summarized the available literature on excess mortality in LLMICs, including methods, data sources, and drivers of excess mortality. Methods A protocol was registered in PROSPERO (ID: CRD42022378267). We searched PubMed, Embase, Web of Science, Cochrane Library, Google Scholar, and Scopus for studies conducted in LLMICs on excess mortality which included at least a one-year non-COVID-19 period as the comparator, and with publication date from 2019 to date. The meta-analysis included studies with extractable data on excess mortality, methods, population size, and observed and expected deaths. We used the Mantel-Haenszel method to estimate the pooled risk ratio with 95% confidence intervals. Results The review included 21 studies (5 from Africa), of which 11 were included in the meta-analysis (2 from Africa). Of 1,405,128,717 individuals, 2,161,846 deaths were expected, and 3,633,661 deaths were reported. The pooled excess mortality was 104.7 deaths per 100,000 population. The risk of excess mortality was 1.68 (95% CI: 1.67, 1.68 p &amp;lt; 0.001). Data sources included public cemeteries, civil registration systems, obituary notifications, surveys, funeral counts, burial site imaging, and demographic surveillance systems. Techniques used to estimate excess mortality were mainly statistical modelling and geospatial analysis. Of the 21 studies, only one reported on drivers of excess mortality and found higher excess mortality in urban settings. Conclusions Our results show that excess mortality in LLMICs during the pandemic was substantial even if it was considerably lower than in high-income countries. There is uncertainty around excess mortality estimates given comparatively weak data. Further studies are needed to identify the drivers of excess mortality by exploring different methods and data sources.

1.C. Workshop: COVID-19 and strategies to improve pandemic preparedness in Africa: Results of 4 systematic reviews

Abstract Background The COVID-19 pandemic has had a massive impact on mortality and health service utilisation globally. However, its impact in low- and lower middle-income countries (LLMIC), in particular in sub-Saharan Africa, remains poorly understood. The German West-African Centre (G-WAC) for Global Health and Pandemic Prevention aims to contribute to a better understanding of the pandemic and to strengthen pandemic preparedness in the region. Objectives The workshop aims to provide an overview of available research on four aspects that are key for understanding the COVID-19 pandemic in sub-Saharan Africa and to support improved pandemic preparedness in the region: (1) the impact of the pandemic on excess mortality, (2) the changes in health services utilisation, (3) the different strategies that support community engagement, and (4) the role of mHealth tools for community-based disease surveillance. Together with workshop participants, we intend to discuss challenges and opportunities for research on the COVID-19 pandemic in sub-Saharan Africa and the potential for research to contribute to better pandemic preparedness. We also wish to receive input for the further research agenda of G-WAC. Added value The workshop will bring together the findings of four systematic reviews that provide complementary evidence contributing to a better understanding of the COVID-19 pandemic in sub-Saharan Africa. It will provide a platform for researchers engaged in related work in Africa or Europe to share their experiences and to contribute to shaping the future research agenda of G-WAC. Coherence of workshop Following a brief introduction explaining the underlying research concept that links the four systematic reviews, results will be presented for: (1) a systematic review and meta-analysis of excess mortality, reporting pooled excess mortality estimates; (2) a scoping review illustrating the range of approaches and settings where research has been conducted on health service utilisation during the pandemic; (3) a scoping review of the various strategies that have been used to foster community engagement to strengthen infection control activities; and (4) a scoping review of different mobile phone-based tools that support Community Health Workers engaged in infectious disease surveillance. Format This is a regular workshop consisting of four brief (7 mins) presentations. Each presentation will be followed by 5 mins discussions, giving room to the audience for questions and comments that relate findings to previous research experiences. Another 10 mins are reserved at the end to discuss further research needs. Several polling rounds will engage the audience and collect input on (a) research experiences in sub-Saharan Africa, (b) reflections about the relevance of presented results, and (c) suggestions for further research. Key messages • The workshop will summarise existing evidence on the impact of the COVID-19 pandemic on mortality and health service utilisation in sub-Saharan Africa. • Community participation may support improved pandemic preparedness and response by contributing to early detection of outbreaks and the successful implementation of infection control activities.

Variations in global prices of chemotherapy for childhood cancer: a descriptive analysis.

The stark disparity in survival for children with cancer across the world has inspired a global call to expand chemotherapy access in low and middle income countries. Among the numerous barriers to success, a paucity of reliable information regarding chemotherapy pricing hinders the ability of governments and other key stakeholders to make informed budget decisions or negotiate lower medication prices. The aim of this study was to generate comparative price information on both individual chemotherapy agents and comprehensive treatment regimens for common childhood cancers using real-world data. Chemotherapy agents were selected based on their inclusion in the World Health Organization (WHO) Essential Medicines List for Children (EMLc) and their use in frontline regimens for the tracer cancer types prioritized by the WHO's Global Initiative for Childhood Cancer (GICC). Sources included IQVIA MIDAS data, obtained under license from IQVIA, and publicly available data from Management Sciences for Health (MSH). Data on chemotherapy prices and purchase volumes spanning 2012-2019 were aggregated according to WHO region and World Bank (WB) income classification. Cumulative chemotherapy prices for treatment regimens were compared across WB income classification. Data representing an estimated 1.1 billion doses of chemotherapy were obtained for 97 countries: 43 high income countries (HICs), 28 upper middle income countries (UMICs), and 26 low and lower middle income countries (LLMICs). Median drug prices in HICs were 0.9-20.4 times those of UMICs and 0.9-15.5 times those of LMICs. Regimen prices were generally higher for HICs, hematologic malignancies, non-adapted protocols, and higher risk stratification or stage, albeit with notable exceptions. This study represents the largest price analysis to date of chemotherapy agents used globally in childhood cancer therapy. The findings of this study form a basis for future cost-effectiveness analysis in pediatric cancer and should inform efforts of governments and stakeholders to negotiate drug prices and develop pooled purchasing strategies.

Association of Country Income Level With the Characteristics and Outcomes of Critically Ill Patients Hospitalized With Acute Kidney Injury and COVID-19

Acute kidney injury (AKI) has been identified as one of the most common and significant problems in hospitalized patients with COVID-19. However, studies examining the relationship betweenCOVID-19 and AKI in low- and low-middle income countries (LLMIC) are lacking. Given that AKI is known to carry a higher mortality rate in these countries, it is important to understand differences in this population. This prospective, observational study examines the AKI incidence and characteristics of 32,210 patients with COVID-19 from 49 countries across all income levels who were admitted to an intensive care unit during their hospital stay. Among patients with COVID-19 admitted to the intensive care unit, AKI incidence was highest in patients in LLMIC, followed by patients in upper-middle income countries (UMIC) and high-income countries (HIC) (53%, 38%, and 30%, respectively), whereas dialysis rates were lowest among patients with AKI from LLMIC and highest among those from HIC (27% vs. 45%). Patients with AKI in LLMIC had the largest proportion of community-acquired AKI (CA-AKI) and highest rate of in-hospital death (79% vs. 54% in HIC and 66% in UMIC). The association between AKI, being from LLMIC and in-hospital death persisted even after adjusting for disease severity. AKI is a particularly devastating complication of COVID-19 among patients from poorer nations where the gaps in accessibility and quality of healthcare delivery have a major impact on patient outcomes.

A bibliometric analysis of global research on drinking water and health in low- and lower-middle-income countries.

Heightened interest in drinking water research in recent decades has been aimed at narrowing the knowledge gaps surrounding water and health in a global pursuit to provide safely managed drinking water services to populations who continue to lack access. This study used bibliometrics and network analysis to produce a global overview of publications and groups that have contributed to research on drinking water and health in low- and lower-middle-income countries (LLMICs). The United States and the United Kingdom, which have historically dominated the field based on the production and impact of scientific literature, remain at the center of international collaborative research partnerships with emerging countries. However, in recent years, the volume of publications produced by India has surpassed that of the United States while Bangladesh is ranked third for the strongest international collaborations. Iran and Pakistan are also emerging as major producers of research, yet publications out of these countries and India remain disproportionately restricted behind paywalls. Contamination, diarrheal disease, and water resources are the themes that characterize the majority of research on water and health. These findings may be used to accelerate equitable, inclusive research in the realm of water and health, thereby enabling gaps in global drinking water inequalities to be filled.

The social determinants of national tuberculosis incidence rates in 116 countries: a longitudinal ecological study between 2005–2015

BackgroundAccelerating declines in tuberculosis (TB) incidence is paramount for achieving global goals set for 2030 by the Sustainable Development Goals and the End TB Strategy. The aim of this study was to identify key country-level social determinants of national TB incidence trends.MethodsThis longitudinal ecological study used country-level data extracted from online databases from the period 2005–2015. We used multivariable Poisson regression models allowing for distinct within- and between-country effects to estimate associations between national TB incidence rates and 13 social determinants of health. The analysis was stratified by country income status.ResultsThe study sample included 48 low- and lower-middle-income countries (LLMICs) and 68 high- and upper-middle income countries (HUMICs), with a total of 528 and 748 observations between 2005–2015, respectively. National TB incidence rates declined in 108/116 countries between 2005–2015, with an average drop of 12.95% in LLMICs and 14.09% in HUMICs. Between LLMICs, higher Human Development Index (HDI), social protection spending, TB case detection, and TB treatment success were associated with lower TB incidence. Higher prevalence of HIV/AIDS was associated with higher TB incidence. Within LLMICs, increases in HDI over time were associated with lower TB incidence rates. Between HUMICs, higher HDI, health spending, and diabetes prevalence were associated with lower TB incidence, whereas higher prevalence of HIV/AIDS and alcohol-use were associated with higher TB incidence. Within HUMICs, increases in HIV/AIDS and diabetes prevalence over time were associated with higher TB incidence.ConclusionsIn LLMICs, TB incidence rates remain highest in countries with low human development, social protection spending and TB programme performance, and high rates of HIV/AIDS. Strengthening human development is likely to accelerate declines in TB incidence. In HUMICs, TB incidence rates remain highest in countries with low human development, health spending and diabetes prevalence, and high rates of HIV/AIDS and alcohol use. Here, slowing rising rates of HIV/AIDS and diabetes is likely to accelerate declines in TB incidence.

Financing and provision of healthcare for two billion people in low-income nations: Is the cooperative healthcare model a solution?

The international consensus in support of universal health coverage (UHC), though commendable, thus far lacks a clear mechanism to finance and deliver accessible and effective basic healthcare to the two billion rural residents and informal workers of low- and lower-middle-income countries (LLMICs). Importantly, the two preferred financing modes for UHC, general tax revenue and social health insurance, are often infeasible for LLMICs. We identify from historical examples a community-based model that we argue shows promise as a solution to this problem. This model, which we call Cooperative Healthcare (CH), is characterized by community-based risk-pooling and governance and prioritizes primary care. CH leverages communities' existing social capital, such that even those for whom the private benefit of enrolling in a CH scheme is outweighed by the cost may choose to enroll (given sufficient social capital). For CH to be scalable, it needs to demonstrate that it can organize delivery of accessible and reasonable-quality primary healthcare that people value, with management accountable to the communities themselves through structures that people trust, combined with government legitimacy. Once LLMICs with CH programs have industrialized sufficiently to make universal social health insurance feasible, CH schemes can be rolled into such universal programs. We defend cooperative healthcare's suitability for this bridging role and urge LLMIC governments to launch experiments testing it out, with careful adaptation to local conditions.

Quality intrapartum care expectations and experiences of women in sub-Saharan African Low and Low Middle-Income Countries: a qualitative meta-synthesis

BackgroundWoman-centred maternity care is respectful and responsive to women’s needs, values, and preferences. Women’s views and expectations regarding the quality of health services during pregnancy and childbirth vary across settings. Despite the need for context-relevant evidence, to our knowledge, no reviews focus on what women in sub-Saharan African Low and Low Middle-Income Countries (LLMICs) regard as quality intrapartum care that can inform quality guidelines in countries.MethodsWe undertook a qualitative meta-synthesis using a framework synthesis to identify the experiences and expectations of women in sub-Saharan African LLMICs with quality intrapartum care. Following a priori protocol, we searched eight databases for primary articles using keywords. We used Covidence to collate citations, remove duplicates, and screen articles using a priori set inclusion and exclusion criteria. Two authors independently screened first the title and abstracts, and the full texts of the papers. Using a data extraction excel sheet, we extracted first-order and second-order constructs relevant to review objectives. The WHO framework for a positive childbirth experience underpinned data analysis.ResultsOf the 7197 identified citations, 30 articles were included in this review. Women’s needs during the intrapartum period resonate with what women want globally, however, priorities regarding the components of quality care for women and the urgency to intervene differed in this context given the socio-cultural norms and available resources. Women received sub-quality intrapartum care and global standards for woman-centred care were often compromised. They were mistreated verbally and physically. Women experienced poor communication with their care providers and non-consensual care and were rarely involved in decisions concerning their care. Women were denied the companion of choice due to cultural and structural factors.ConclusionTo improve care seeking and satisfaction with health services, woman-centred care is necessary for a positive childbirth experience. Women must be meaningfully engaged in the design of health services, accountability frameworks, and evaluation of maternal services. Research is needed to set minimum indicators for woman-centred outcomes for low-resource settings along with actionable strategies to enhance the quality of maternity care based on women’s needs and preferences.

Maternal and paternal employment in agriculture and early childhood development: A cross-sectional analysis of Demographic and Health Survey data.

Considerable literature from low- and lower-middle-income countries (LLMICs) links maternal employment to child nutritional status. However, less is known about the role of parental employment and occupation type in shaping child development outcomes. Additionally, little empirical work has examined the mechanisms through which parental occupation influences child outcomes. Our objective was to investigate the associations between maternal and paternal employment (comparing agricultural and non-agricultural employment) and child development and to examine childcare practices and women's empowerment as potential mechanisms. We pooled nine Demographic and Health Surveys (Benin, Burundi, Cambodia, Congo, Haiti, Rwanda, Senegal, Togo, and Uganda) with data on 8,516 children aged 36-59 months. We used generalised linear models to estimate associations between parental employment and child development, child stimulation (number of activities provided by the mother, father, and other household members), child supervision (not left alone or with older child for >1 hour), early childhood care and education programme (ECCE) attendance, and women's empowerment. In our sample, all fathers and 85% of mothers were employed. In 40% of families, both parents were employed in agriculture. After adjusting for child, parental and household confounders, we found that parental agricultural employment, relative to non-agricultural employment, was associated with poorer child development (relative risk (RR) 0.86 (95% CI 0.80, 0.92), more child stimulation provided by other household members (mean difference (MD) 0.26 (95% CI 0.09, 0.42)), less adequate child supervision (RR, 0.83 (95% 0.78, 0.80)), less ECCE attendance (RR 0.46 (95% CI 0.39, 0.54)), and lower women's empowerment (MD -1.01 (95% CI -1.18, -0.84)). Parental agricultural employment may be an important risk factor for early childhood development. More research using more comprehensive exposure and outcome measures is needed to unpack these complex relationships and to inform interventions and policies to support working parents in the agricultural sector with young children.

School-based socio-emotional learning programs to prevent depression, anxiety and suicide among adolescents: a global cost-effectiveness analysis.

Preventing the occurrence of depression/anxiety and suicide during adolescence can lead to substantive health gains over the course of an individual person's life. This study set out to identify the expected population-level costs and health impacts of implementing universal and indicated school-based socio-emotional learning (SEL) programs in different country contexts. A Markov model was developed to examine the effectiveness of delivering universal and indicated school-based SEL programs to prevent the onset of depression/anxiety and suicide deaths among adolescents. Intervention health impacts were measured in healthy life years gained (HLYGs) over a 100-year time horizon. Country-specific intervention costs were calculated and denominated in 2017 international dollars (2017 I$) under a health systems perspective. Cost-effectiveness findings were subsequently expressed in terms of I$ per HLYG. Analyses were conducted on a group of 20 countries from different regions and income levels, with final results aggregated and presented by country income group - that is, low and lower middle income countries (LLMICs) and upper middle and high-income countries (UMHICs). Uncertainty and sensitivity analyses were conducted to test model assumptions. Implementation costs ranged from an annual per capita investment of I$0.10 in LLMICs to I$0.16 in UMHICs for the universal SEL program and I$0.06 in LLMICs to I$0.09 in UMHICs for the indicated SEL program. The universal SEL program generated 100 HLYGs per 1 million population compared to 5 for the indicated SEL program in LLMICs. The cost per HLYG was I$958 in LLMICS and I$2,006 in UMHICs for the universal SEL program and I$11,123 in LLMICs and I$18,473 in UMHICs for the indicated SEL program. Cost-effectiveness findings were highly sensitive to variations around input parameter values involving the intervention effect sizes and the disability weight used to estimate HLYGs. The results of this analysis suggest that universal and indicated SEL programs require a low level of investment (in the range of I$0.05 to I$0.20 per head of population) but that universal SEL programs produce significantly greater health benefits at a population level and therefore better value for money (e.g., less than I$1,000 per HLYG in LLMICs). Despite producing fewer population-level health benefits, the implementation of indicated SEL programs may be justified as a means of reducing population inequalities that affect high-risk populations who would benefit from a more tailored intervention approach.

Hypofractionation in Breast Cancer Radiotherapy Across World Bank Income Groups: Results of an International Survey.

Hypofractionated breast radiotherapy has been found to be equivalent to conventional fractionation in many clinical trials. Using data from the European Society for Radiotherapy and Oncology Global Impact of Radiotherapy in Oncology survey, we identified preferences for hypofractionation in breast cancer across World Bank income groups and the perceived facilitators and barriers to its use. An international, electronic survey was administered to radiation oncologists from 2018 to 2019. Demographics, practice characteristics, preferred hypofractionation regimen for specific breast cancer scenarios, and facilitators and barriers to hypofractionation were reported and stratified by World Bank income groups. Variables associated with hypofractionation were assessed using multivariate logistic regression models. One thousand four hundred thirty-four physicians responded: 890 (62%) from high-income countries (HICs), 361 (25%) from upper-middle-income countries (UMICs), 183 (13%) from low- and lower-middle-income countries (LLMICs). Hypofractionation was preferred most frequently in node-negative disease after breast-conserving surgery, with the strongest preference reported in HICs (78% from HICs, 54% from UMICs, and 51% from LLMICs, P < .001). Hypofractionation for node-positive disease postmastectomy was more frequently preferred in LLMICs (28% from HICs, 15% from UMICs, and 35% from LLMICs, P < .001). Curative doses of 2.1 to < 2.5 Gy in 15-16 fractions were most frequently reported, with limited preference for ultra-hypofractionation, but significant variability in palliative dosing. In adjusted analyses, UMICs were significantly less likely than LLMICs to prefer hypofractionation across all curative clinical scenarios, whereas respondents with > 1 million population catchments and with intensity-modulated radiotherapy were more likely to prefer hypofractionation. The most frequently cited facilitators and barriers were published evidence and fear of late toxicity, respectively. Preference for hypofractionation varied for curative indications, with greater acceptance in earlier-stage disease in HICs and in later-stage disease in LLMICs. Targeted educational interventions and greater inclusivity in radiation oncology clinical trials may support greater uptake.

Health system capacity to manage diabetic ketoacidosis in nine low-income and lower-middle income countries: A cross-sectional analysis of nationally representative survey data.

There has been increasing awareness about the importance of type 1 diabetes (T1D) globally. Diabetic ketoacidosis (DKA) is a life-threatening complication of T1D in low-income settings. Little is known about health system capacity to manage DKA in low- and lower-middle income countries (LLMICs). As such, we describe health system capacity to diagnose and manage DKA across nine LLMICs using data from Service Provision Assessments. In this cross-sectional study, we used data from Service Provision Assessment (SPA) surveys, which are part of the Demographic and Health Survey (DHS) Program. We defined an item set to diagnose and manage DKA in higher-level (tertiary or secondary) facilities, and a set to assess and refer patients presenting to lower-level (primary) facilities. We quantified each item's availability by service level in Bangladesh (Survey 1: May 22 2014-Jul 20 2014; Survey 2: Jul 2017-Oct 2017), the Democratic Republic of the Congo (DRC) (Oct 16 2017-Nov 24 2017 in Kinshasha; Aug 08 2018-Apr 20 2018 in rest of country), Haiti (Survey 1: Mar 05 2013-Jul 2013; Survey 2: Dec 16 2017-May 09 2018), Ethiopia (Feb 06 2014-Mar 09 2014), Malawi (Phase 1: Jun 11 2013-Aug 20 2013; Phase 2: Nov 13 2013-Feb 7 2014), Nepal (Phase 1: Apr 20 2015-Apr 25 2015; Phase 2: Jun 04 2015-Nov 05 2015), Senegal (Survey 1: Jan 2014-Oct 2014; Survey 2: Feb 09 2015-Nov 10 2015; Survey 3: Feb 2016-Nov 2016; Survey 4: Mar 13 2017-Dec 15 2017; Survey 5: Apr 15 2018-Dec 31 2018; Survey 6: Apr 15 2019-Feb 28 2020), Tanzania (Oct 20 2014-Feb 21 2015), and Afghanistan (Nov 1 2018-Jan 20 2019). Variation in secondary facilities' capacity and trends over time were also explored. We examined data from 2028 higher-level and 7534 lower-level facilities. Of these, 1874 higher-level and 6636 lower-level facilities' data were eligible for analysis. Availability of all item sets were low at higher-level facilities, where less than 50% had the minimal set of supplies, less than 20% had the full minimal set, and less than 15% had the ideal set needed to diagnose and manage DKA. Across countries in lower-level facilities, less than 14% had the minimal set of supplies and less than 9% the full set of supplies for diagnosis and transfer of DKA patients. No country had more than 20% of facilities with the minimal set of items needed to assess or manage DKA. Where data were available for more than one survey (Bangladesh, Senegal, and Haiti), changes in availability of the minimal set and ideal set of items did not exceed 15%. Tertiary facilities performed best in Haiti, Ethiopia, Malawi, Nepal, Senegal, Tanzania, and Afghanistan. Secondary facilities that were rural, public, and had fewer staff had lower capacity. Health system capacity to manage DKA was low across these nine LLMICs. Although efforts are underway to strengthen health systems, a specific focus on DKA management is still needed.

Defining the Current Deployment of Neonatal Infusion Pumps in Low- and Lower-Middle-Income Countries: A Rapid Review.

There has been limited review of the reported deployment of infusion pumps in low- and lower-middle-income countries. This paper aims to identify the current distribution of infusion pumps in low- and lower-middle-income countries (LLMICs) used to treat neonates. A rapid review was conducted using material sourced from ProQuest, Pubmed, Web of Science, and IEEE Xplore. Twenty-six search results met the inclusion criteria. Within these, 41 neonatal healthcare facilities were discussed with 17 of the facilities having infusion pumps available, 13 limited access, and 11 none. Infusion pump use remains limited in Sub-Saharan Africa so efforts should be made to deploy specialist neonatal care improvement packages, potentially including infusion pumps designed for LLMICs. The effects of COVID-19, to neonatal care LLMICs, should be accessed to ensure progress has not regressed. These proposals aim to aid in the continued improvement of neonatal care globally and reduce newborn mortalities.
