Background: Food quality and safety concerns in low- and middle-income countries are often addressed using stringent standards and formal contracts between farmers and buyers. Many studies have investigated the welfare implications of these control mechanisms for small-scale farmers in modern value chains, including exports and supermarkets. Conversely, few studies have focused on the potential of certification and contracts to tackle food safety issues within local traditional value chains. Methods: This study uses a discrete choice experiment to explore the preferences of vegetable farmers (n = 301) in northern Vietnam for different types of certification schemes–including third-party certification and participatory guarantee systems–and contracts. Results: Farmers are willing to accept a 49% lower price per kilogram for their vegetables to enter into a contract with a buyer, provided that pesticide use restrictions are feasible and the buyer is fully committed and trustworthy. However, they are strongly averse to organic farming, as they would require a 40% premium per kilogram to produce organically. They would also request a 21% premium to accept selling to an unknown buyer. Farmers highly value contracts that entail large purchase quantities, long duration and pesticide provision. Although the estimated willingness-to-accept values may seem very large, they make sense in the context of highly perishable produce. Conclusion: Our findings urge both policy makers and researchers to not only focus on modern value chains but also on local traditional value chains to tackle food safety issues in low- and middle-income countries, as we show that farmers are willing to produce safe vegetables for the local market when trading with buyers under beneficial conditions.

Older populations are rising globally, which in high-income countries has helped to generate a growing literature on the impact of ageing on travel requirements and transport policy. This article aims to provide an initial assessment of the state of knowledge on the impact on transportation policy and usage of the increasing numbers of older people in low- and middle-income countries (LAMICs), through a review of the literature relating to older people and transportation. As both the academic and policy/practice-related literature specifically addressing ageing and transport in LAMICs is limited, the study looks beyond transportation to assess the state of knowledge regarding the ways in which older people’s mobility is affected by issues, such as health, well-being, social (dis)engagement and gender. We find significant knowledge gaps, resulting in an evidence base to support the implementation of policy is lacking. Most research in low-income countries (LICs) is either broad quantitative analysis based on national survey data or small-scale qualitative studies. We conclude that, although study of the differing contexts of ageing in LAMICs as they relate to older people’s mobilities and transport use has barely begun, institutions which both make and influence policymaking recognise the existence of significant knowledge gaps. This should provide the context in which research agendas can be established.

OBJECTIVEWorldwide disparities in the provision of surgical care result in otherwise preventable disability and death. There is a growing need to quantify the global burden of neurosurgical disease specifically, and the workforce necessary to meet this demand.METHODSResults from a multinational collaborative effort to describe the global neurosurgical burden were aggregated and summarized. First, country registries, third-party modeled data, and meta-analyzed published data were combined to generate incidence and volume figures for 10 common neurosurgical conditions. Next, a global mapping survey was performed to identify the number and location of neurosurgeons in each country. Finally, a practitioner survey was conducted to quantify the proportion of disease requiring surgery, as well as the median number of neurosurgical cases per annum. The neurosurgical case deficit was calculated as the difference between the volume of essential neurosurgical cases and the existing neurosurgical workforce capacity.RESULTSEvery year, an estimated 22.6 million patients suffer from neurological disorders or injuries that warrant the expertise of a neurosurgeon, of whom 13.8 million require surgery. Traumatic brain injury, stroke-related conditions, tumors, hydrocephalus, and epilepsy constitute the majority of essential neurosurgical care worldwide. Approximately 23,300 additional neurosurgeons are needed to address more than 5 million essential neurosurgical cases—all in low- and middle-income countries—that go unmet each year. There exists a gross disparity in the allocation of the surgical workforce, leaving large geographic treatment gaps, particularly in Africa and Southeast Asia.CONCLUSIONSEach year, more than 5 million individuals suffering from treatable neurosurgical conditions will never undergo therapeutic surgical intervention. Populations in Africa and Southeast Asia, where the proportion of neurosurgeons to neurosurgical disease is critically low, are especially at risk. Increasing access to essential neurosurgical care in low- and middle-income countries via neurosurgical workforce expansion as part of surgical system strengthening is necessary to prevent severe disability and death for millions with neurological disease.

Our review explores the changing food production, distribution and consumption environment in low and middle-income countries and emerging economies as a basis for framing how to study food systems in order to address public health issues of food safety and nutrition. It presents the state of knowledge on existing food systems science and its use in terms of sustainable actions for food safety and public health. The review identifies a knowledge gap in food system mapping and governance, with value chain mapping of key commodities often missing. Despite a number of initiatives, the application of food systems methods is highly variable in scope and quality. Most analyses concentrate on specific commodities, rarely taking into account the need for a whole diet approach when looking at nutrition or the assessment of a range of infectious agents and their interactions when looking at food safety. Of the studies included in the review there is a growing observation of “informal” food systems, a term used inconsistently and one that requires revision. “Informal” food systems link to the formal sector to provide food security, yet with trade-offs between economic efficiencies and food safety. Efforts to improve food safety are hampered by inadequate food safety capacities and a lack of policy coherence leading to: inadequate investment; fragmented food quality control systems; weak or non-existent traceability mechanisms; weak foodborne disease surveillance; obsolete food regulation; and weak regulatory enforcement. In-depth food systems assessments can complement risk analysis to identify risky behaviors and understand institutional settings in order to improve codes of practice and enforcement. Methods for looking at food safety from a food systems perspective are emerging, yet existing nutrition and food systems science are not advancing sufficiently in response to nutritional public health problems. There is an urgency for improved understanding of the structure and drivers of the food systems, for better planning of changes that leads to nutrients access and healthy levels of eating. It is proposed that countries and international institutions provide an atlas of food system maps for the key commodities based on an agreed common methodology and developed by multidisciplinary teams.

Objective: Rapid urbanization and industrialization in the many low- and middle-income countries means that there is a growing demand for the welding industry. Previous studies in Nigeria, and other low- and middle-income countries have reported a significant discrepancy between awareness and consistent and appropriate use of personal protective equipment (PPE). This study assessed the awareness and utilization of PPE among small-scale welders in Calabar South, Cross River State, Nigeria. Methods: This study was conducted in Calabar South Local Government Area using a descriptive cross-sectional design. Data collection was with an interviewer-administered semi-structured questionnaire, and an observation checklist was used to monitor the use of PPE among small-scale welders. Results:  One hundred and sixteen small-scale welders were surveyed with a mean age of 34.9 ±9.1 years. Almost 90% of respondents had completed at least primary education. Eighty-one respondents (69.8%) were aware of PPE. Three-quarters of respondents (61/81) knew PPE protected the user from injury. The most frequently identified type of welding PPE among the respondents aware of PPE, were safety goggles (38.3%), hand gloves (25.9%), safety boots (19.8%), and coveralls (9.9%). 83.6% had access to PPE at work. However, only 14.4% reported using PPE consistently. Observation revealed that the PPE most frequently used, sunglasses, were not the recommended welding goggles. Conclusion:  The low utilization of PPE calls for stricter enforcement of occupational health and safety regulations among welders in the informal sector, including implementing PPE awareness programs.

Abstract Background Low- and middle-income countries (LMICs) experienced increasing rates of colorectal cancer (CRC) incidence in the last decade and lower 5-year survival rates compared to high-income countries (HICs) where the implementation of screening and treatment services have advanced. This review scoped and mapped the literature regarding the content, implementation and uptake of CRC screening interventions as well as opportunities and challenges for the implementation of CRC screening interventions in LMICs. Methods We systematically followed a five-step scoping review framework to identify and review relevant literature about CRC screening in LMICs, written in the English language before February 2020. We searched Medline, Embase, Web of Science and Google Scholar for studies targeting the general, asymptomatic, at-risk adult population. The TIDieR tool and an implementation checklist were used to extract data from empirical studies; and we extracted data-informed insights from policy reviews and commentaries. Results CRC screening interventions (n = 24 studies) were implemented in nine middle-income countries. Population-based screening programmes (n = 11) as well as small-scale screening interventions (n = 13) utilised various recruitment strategies. Interventions that recruited participants face-to-face (alone or in combination with other recruitment strategies) (10/15), opportunistic clinic-based screening interventions (5/6) and educational interventions combined with screening (3/4), seemed to be the strategies that consistently achieved an uptake of > 65% in LMICs. FOBT/FIT and colonoscopy uptake ranged between 14 and 100%. The most commonly reported implementation indicator was ‘uptake/reach’. There was an absence of detail regarding implementation indicators and there is a need to improve reporting practice in order to disseminate learning about how to implement programmes. Conclusion Opportunities and challenges for the implementation of CRC screening programmes were related to the reporting of CRC cases and screening, cost-effective screening methods, knowledge about CRC and screening, staff resources and training, infrastructure of the health care system, financial resources, public health campaigns, policy commitment from governments, patient navigation, planning of screening programmes and quality assurance.

Low And Middle Income

The rise of small-scale and localized economic activities in low- and middle-income countries (LMICs) has led to increased exposures to contaminants associated with these processes and the potential for resulting adverse health effects in exposed communities. Risk assessment is the process of building models to predict the probability of adverse outcomes based on concentration-response functions and exposure scenarios for individual contaminants, while epidemiology uses statistical methods to explore associations between potential exposures and observed health outcomes. Neither approach by itself is practical or sufficient for evaluating the magnitude of exposures and health impacts associated with land-based pollution in LMICs. Here we propose a more pragmatic framework for designing representative studies, including uniform sampling guidelines and household surveys, that draws from both methodologies to better support community health impact analyses associated with land-based pollution sources in LMICs. Our primary goal is to explicitly link environmental contamination from land-based pollution associated with specific localized economic activities to community exposures and health outcomes at the household level. The proposed framework was applied to the following three types of industries that are now widespread in many LMICs: artisanal scale gold mining (ASGM), used lead-acid battery recycling (ULAB), and small tanning facilities. For each activity, we develop a generalized conceptual site model (CSM) that describes qualitative linkages from chemical releases or discharges, environmental fate and transport mechanisms, exposure pathways and routes, populations at risk, and health outcomes. This upfront information, which is often overlooked, is essential for delineating the contaminant zone of influence in a community and identifying relevant households for study. We also recommend cost-effective methods for use in LMICs related to environmental sampling, biological monitoring, survey questionnaires, and health outcome measurements at contaminated and unexposed reference sites. Future study designs based on this framework will facilitate consistent, comparable, and standardized community exposure, risk, and health impact assessments for land-based pollution in LMICs. The results of these studies can also support economic burden analyses and risk management decision-making around site cleanup, risk mitigation, and public health education.

IntroductionSustainability remains poorly defined in global surgery, yet is, nevertheless, crucial to the work of non-governmental organisations (NGOs) in low- and middle-income countries (LMICs) aimed at strengthening access to, and quality of, surgical and anaesthesia care. The objective of this protocol is to outline a scoping review that maps what is known in the literature about sustainability in NGO surgical work in LMICs.MethodsThe application of Arksey and O’Malley’s six-stage methodological framework is described: identifying research questions; identifying relevant publications; selecting publications; charting the data; reporting results; and stakeholder consultation. The review will include all study designs, as well as editorials, commentaries, sources of unpublished studies and grey literature. Three electronic databases will be searched. Two reviewers will use predefined and iteratively refined selection criteria based on the ‘Population–Concept–Context’ framework to independently screen titles and abstracts of citations from the search. Disagreements will be resolved together by the reviewers. Full-text screening will also be carried out independently by two reviewers. Disagreements at this stage will be resolved with a third party. The search strategy for grey literature will include searching in ProQuest Dissertations and Theses and the websites listed in a surgical NGO database. Further relevant citations will be identified by screening the reference lists of the included papers.Ethics and disseminationThis review will undertake a secondary analysis of data already collected and does not require ethical approval. The results will be disseminated through journals and conferences targeting surgical NGO stakeholders and global health academics.

Anaerobic digestion (AD) systems are prominent in low- and middle-income countries (LMICs), although their implementation within organic farms to enhance resource efficiency and “close the loop” has been limited. This paper thus reviewed existing literature on the potential of AD technologies as part of closed-loop rural family farming communities in LMICs. Data from eleven existing case studies matching this criterion was then collated to understand practical considerations of implementing and maintaining viable AD systems for small farmers. The case studies analyzed indicate that most, if not all, of the biogas produced in the AD process is used for household purposes such as cooking, lighting and heating. The AD systems are either based on the fixed biogas dome or the floating drum design, although the tubular flexible balloon model is mentioned as a low-cost alternative. Future research opportunities in this topic include studying the applicability of recommendations offered across different geographies, consideration of long-term sustainability and impact of biodigester technology, and sociocultural factors such as community ownership and indigenous practices.
