Summary Despite the acknowledged injustice and widespread existence of parachute research studies conducted in low‐ or middle‐income countries by researchers from institutions in high‐income countries, there is currently no pragmatic guidance for how academic journals should evaluate manuscript submissions and challenge this practice. We assembled a multidisciplinary group of editors and researchers with expertise in international health research to develop this consensus statement. We reviewed relevant existing literature and held three workshops to present research data and holistically discuss the concept of equitable authorship and the role of academic journals in the context of international health research partnerships. We subsequently developed statements to guide prospective authors and journal editors as to how they should address this issue. We recommend that for manuscripts that report research conducted in low‐ or middle‐income countries by collaborations including partners from one or more high‐income countries, authors should submit accompanying structured reflexivity statements. We provide specific questions that these statements should address and suggest that journals should transparently publish reflexivity statements with accepted manuscripts. We also provide guidance to journal editors about how they should assess the structured statements when making decisions on whether to accept or reject submitted manuscripts. We urge journals across disciplines to adopt these recommendations to accelerate the changes needed to halt the practice of parachute research.

Air pollution adversely affects human health, and the climate crisis intensifies the global imperative for action. Low-/middle-income countries (LMIC) suffer particularly high attributable disease burdens. In rural low-resource settings, these are linked to cooking using biomass. Proposed biomedical solutions to air pollution typically involve ‘improved cooking technologies’, often introduced by high-income country research teams. This ethnography, set in a rural Malawian village, aimed to understand air pollution within its social and environmental context. The results provide a multifaceted account through immersive participant observations with concurrent air quality monitoring, interviews and participatory workshops. Data included quantitative measures of individuals’ air pollution exposures paired with activity, qualitative insights into how smoke is experienced in daily life throughout the village, and participants’ reflections on potential cleaner air solutions. Individual air quality monitoring demonstrated that particulate levels frequently exceeded upper limits recommended by the WHO, even in the absence of identified sources of biomass burning. Ethnographic findings revealed the overwhelming impact of economic scarcity on individual air pollution exposures. Scarcity affected air pollution exposures through three pathways: daily hardship, limitation and precarity. We use the theory of structural violence, as described by Paul Farmer, and the concept of slow violence to interrogate the origins of this scarcity and global inequality. We draw on the ethnographic findings to critically consider sustainable approaches to cleaner air, without re-enacting existing systemic inequities.

Background Compensation for research participants can be provided for reasons including reimbursement of costs; compensation for time lost, discomfort or inconvenience; or expression of appreciation for participation. This compensation involves numerous ethical complexities, at times entailing competing risks. In the context of transnational research, often incorporating contexts of economic inequality, power differentials and post-colonialism, these issues extend into wider questions of ethical research conduct. Methods We describe experiences of conducting a community-based study of air pollution in southern Malawi incorporating ethnographic, participatory and air quality monitoring elements. Decisions surrounding participant compensation evolved in response to changing circumstances in the field. Results Attention to careful researcher–participant relationships and responsiveness to community perspectives allowed dynamic, contextualised decision-making around participant compensation. Despite widely cited risks, including but not restricted to undue influence of monetary compensation on participation, we learned that failure to adequately recognise and compensate participants has its own risks, notably the possibility of ‘ethics dumping’. Conclusions We recommend active engagement with research participants and communities with integration of contextual insights throughout, including participant compensation, as for all elements of research conduct. Equitable research relationships encompass four central values: fairness, care, honesty and respect.

BACKGROUND: Indoor and ambient air pollution exposure is a major risk to respiratory health worldwide, particularly in low- and middle-income countries (LMICs). Interventional trials have mainly focused on alternatives to cooking stoves, with mixed results. Beyond cooking, additional sources of particulate matter also contribute to the burden of air pollution exposure. This review explores evidence from current randomised controlled trials (RCTs) on the clinical effectiveness of interventions to reduce particulate matter in LMICs.METHODS: Twelve databases and the grey literature (e.g., Government reports and policy papers) were searched. Eligible studies were RCTs conducted in LMICs aiming to reduce particulate exposure from any source and reporting on at least one clinical respiratory outcome (respiratory symptoms, lung function or clinical diagnoses). Data from relevant studies were systematically extracted, the risk of bias assessed and narrative synthesis provided.RESULTS: Of the 14 included studies, 12 tested ‘improved' cookstoves, most using biomass, but solar and bioethanol cookers were also included. One trial used solar lamps and another was an integrated intervention incorporating behavioural and environmental components for the treatment and prevention of chronic obstructive pulmonary disease. Of the six studies reporting child pneumonia outcomes, none demonstrated significant benefit in intention-to-treat analysis. Ten studies reported respiratory symptom outcomes with some improvements seen, but self-reporting made these outcomes highly vulnerable to bias. Substantial inter-study clinical and methodological heterogeneity precluded calculation of pooled effect estimates.CONCLUSION: Evidence from the RCTs performed to date suggests that individual household-level interventions for air pollution exposure reduction have limited benefits for respiratory health. More comprehensive approaches to air pollution exposure reduction must be developed so their potential health benefits can be assessed.

BackgroundChronic lung diseases contribute to the growing non-communicable disease (NCD) burden and are increasing, particularly in many low and middle-income countries (LMIC) in sub-Saharan African. Early engagement with health systems in chronic lung disease management is critical to maintain quality of life and prevent further damage. Our study sought to understand health seeking behaviour in relation to chronic lung disease and TB in a rural district in Malawi.MethodsQualitative data was collected between March-May 2015, exploring patterns of health seeking for lung disease amongst residents of two districts in rural Malawi. Participants included those with and without lung disease, health workers and village leaders. Participants with a history of TB were included in the sample due to similarities in clinical presentation and in view of potential to cause long-term damage to lung tissue.ResultsOur findings are ordered around a specific model of health seeking devised by adapting previous models. The model and findings span three broad areas that were found to influence health seeking: understandings of health and disease which shaped whether, when and where to seek care; the care seeking decision which was influenced by social and structural factors; and the care seeking experience which impacted future care decisions creating ‘feedback loops’.DiscussionEfforts to improve effective and accessible healthcare provision for chronic lung disease need to address all the determinants of health seeking behaviour identified. This may include: enhancing the structural and financial accessibility of health services, through the strengthening of community linkages; improving communication between formal health providers, patients and communities around symptoms, diagnosis and management of chronic lung diseases; and improving the quality of diagnostic and management services through the strengthening of health systems ‘hardware’ (equipment availability) and ‘software’ (development of trusting and respectful relationships between providers and patients).

Obesity is a growing epidemic in the western world. We carried out a comparative analysis of the incidence of obstetric morbidity in three BMI categories in the ranges 30-40 to identify which BMI category was associated with greatest risk. This identification could help target limited maternity care resources to the group of women who would benefit most. There exists a scale continuum of risk of obstetric morbidity with maternal obesity: the greater the BMI, the greater the risk. However, pregnant women with mild or moderate obesity are still at significant risk of having pre-existing co-morbidities of developing antenatal complications and of being delivered by caesarean section than women with BMIs within the normal range. These women, at the time of antenatal booking, are currently not perceived by healthcare providers as having at-risk pregnancies and are therefore potentially denied access to best care.

Haemorrhage is one of the leading global causes of maternal mortality. The Rüsch balloon has been used in the treatment of postpartum haemorrhage (PPH) after failure of medical management. It is often effective in tamponading uterine bleeding, thus providing an alternative to hysterectomy. We describe a series of 22 cases in which we used the Rüsch balloon to control massive obstetric haemorrhage after failure to control haemorrhage by medical means. In our study, 13 out of 22 patients (59.1%) required no further interventions after balloon tamponade. Seven patients (31.8%) required hysterectomy to control the bleeding. We include a review of the current literature on balloon tamponade for PPH, including analysis of six relevant case series. This demonstrates a variety of methods based on tamponade to terminate uterine haemorrhage. Our study highlights the benefit of balloon tamponade for massive PPH and the importance of its involvement in labour ward protocols.
