Maternal and offspring pools of osteocalcin influence brain development and functions.

The powerful regulation of bone mass exerted by the brain suggests the existence of bone-derived signals modulating this regulation or other functions of the brain. We show here that the osteoblast-derived hormone osteocalcin crosses the blood-brain barrier, binds to neurons of the brainstem, midbrain, and hippocampus, enhances the synthesis of monoamine neurotransmitters, inhibits GABA synthesis, prevents anxiety and depression, and favors learning and memory independently of its metabolic functions. In addition to these postnatal functions, maternal osteocalcin crosses the placenta during pregnancy and prevents neuronal apoptosis before embryos synthesize this hormone. As a result, the severity of the neuroanatomical defects and learning and memory deficits of Osteocalcin(-/-) mice is determined by the maternal genotype, and delivering osteocalcin to pregnant Osteocalcin(-/-) mothers rescues these abnormalities in their Osteocalcin(-/-) progeny. This study reveals that the skeleton via osteocalcin influences cognition and contributes to the maternal influence on fetal brain development.

Factors influencing the emergence of self-reliance in primary health care using traditional medicine: A scoping review.

Self-reliance is the responsible behavior and the ability of an individual to take care of one's own health using local resources. A substantial proportion of the population use traditional medicine (TM) for primary health care (PHC) in low- and middle-income countries (LMIC). The underlying philosophy of the TM approach is self-reliance due to its emphasis on culture, traditions, customs, and local resources. Given the complexity and ambiguity of how self-reliance emerges, there is a need to have clarity in its understanding and the practice in relation to TM. Hence, we conducted this review to synthesize the factors determining the emergence of self-reliance in PHC using TM in resource-poor settings with a specific focus on LMICs. We searched PubMed, Google scholar, and the Social Science Research Network databases, and conducted reference tracking of selected articles. We included articles published between 2000 and 2020 May. Thematic analysis was done using QDA-miner Lite software version 2.1. We retained 29 papers for review and analysis. A conceptual framework was developed that located factors influencing the emergence of self-reliance. Self-reliance manifests through a socially constructed interaction between factors from the macro (policy and environment) to the micro context (community and household). Due to the lack of explanatory models, there is a substantial gap between understanding self-reliance and its application in health policy and practice. Achieving comprehensive PHC and universal health coverage requires policy provisions to create an enabling environment in health-care facilities, communities, and households that allows the emergence of self-reliance.

Coproducing tobacco control knowledge: Using virtual platforms to strengthen implementation in India.

Tobacco control is complex and multidimensional. In India, 266.8 million adults use tobacco in some form, with local contextual factors shaping its consumption, production, and trade. Actors have a stake in tobacco represent different sectors; with varying priorities, responding to different ideas, and exerting varying levels of influence often make it difficult to work collaboratively on tobacco control-related issues. Through online networking platforms such as webinars, we emphasize how coproduction of tobacco control knowledge enables participation, prioritizes multisectoral strategies, and enhances tobacco control leadership among policymakers and implementers in their settings. Coproduction of knowledge between and across stakeholders with a focus on "how to" implement tobacco control policies can leverage in negotiating and supplementing the policy implementation process.

An intersectional analysis of the composite index of anthropometric failures in India.

BACKGROUND: Nutritional inequality in India has been estimated typically using stunting, wasting and underweight separately which hide the overall magnitude and severity of undernutrition. We used the Composite Index of Anthropometric Failure (CIAF) that combines all three forms of anthropometric failures to assess the severity of undernutrition and identify the most vulnerable social groups and geographical hotspots. METHOD: CIAF was constructed using child anthropometric data from the fourth round of the National Family Health Survey (NFHS-4, 2015-16). We considered 24 intersecting sub-groups based on intersections across four main axes of inequality i.e., caste [Scheduled Tribe (ST), Scheduled Caste (SC) and Other], economic position (poor and non-poor), place of residence (rural and urban) and gender (male and female) (eg. ST-Poor-Rural-Female). Cross-tabulation and logistic regression were done to assess the odds of CIAF among intersecting groups and to identify the most vulnerable sub-groups. Concentration curve was plotted to visualise economic position inequality in child undernutrition across caste categories. Choropleth maps were constructed and descriptive analysis of the district-level prevalence of CIAF was performed to identify the geographic clustering of undernutrition. RESULTS: Overall 55.32% of children were undernourished by CIAF and 6.62% of children have simultaneous three anthropometric failure. In sub-group analysis, children from ST and SC caste have a higher risk of undernutrition irrespective of other axis of inequality. Compared with CIAF, economic position inequality was amplified for simultaneous-three-failures among all caste categories. Economic position inequalities within caste are more for other caste and SC categories than with ST. Economic position, caste and gender based inequality in all three failures is more consistent in rural areas than with urban areas. Based on the analysis of the high prevalence in the co-occurrence of two or three failures, 111 districts from 12 of 29 states in India were identified across four geographic clusters. CONCLUSIONS: The study shows social and eco-geographical clustering of multi-dimensional anthropometric failures and indicates the need for focused nutritional interventions among SC and ST community in general and ST children from the poor households. Furthermore, governance interventions that target entire regions across districts and states combined with decentralised planning are needed.

Improving access to medicines for non-communicable diseases in rural primary care: results from a quasi-randomized cluster trial in a district in South India.

BACKGROUND: A large proportion of non-communicable diseases (NCDs) are treatable within primary health care (PHC) settings in a cost-effective manner. However, the utilization of PHCs for NCD care is comparatively low in India. The Access-to-Medicines (ATM) study examined whether (and how) interventions aimed at health service optimization alone or combined with community platform strengthening improve access to medicines at the primary health care level within the context of a local health system. METHOD: A quasi-randomized cluster trial was used to assess the effectiveness of the intervention (18 months) implemented across 39 rural PHCs (clusters) of three sub-districts of Tumkur in southern India. The intervention was allocated randomly in a 1:1:1 sequence across PHCs and consisted of three arms: Arm A with a package of interventions aimed at health service delivery optimization; B for strengthening community platforms in addition to A; and the control arm. Group allocation was not blinded to providers and those who assessed outcomes. A household survey was used to understand health-seeking behaviour, access and out-of-pocket expenditure (OOP) on key anti-diabetic and anti-hypertension medicines among patients; facility surveys were used to assess the availability of medicines at PHCs. Primary outcomes of the study are the mean number of days of availability of antidiabetic and antihypertensive medicines at PHCs, the mean number of patients obtaining medicines from PHC and OOP expenses. RESULT: The difference-in-difference estimate shows a statistically insignificant increase of 31.5 and 11.9 in mean days for diabetes and hypertension medicines availability respectively in the study arm A PHCs beyond the increase in the control arm. We further found that there was a statistically insignificant increase of 2.2 and 3.8 percentage points in the mean proportion of patients obtaining medicines from PHC in arm A and arm B respectively, beyond the increase in the control arm. CONCLUSION: There were improvements in NCD medicine availability across PHCs, the number of patients accessing PHCs and reduction in OOP expenditure among patients, across the study arms as compared to the control arm; however, these differences were not statistically significant. TRIAL REGISTRATION: Trial registration number CTRI/2015/03/005640 . This trial was registered on 17/03/2015 in the Clinical Trial Registry of India (CTRI) after PHCs were enrolled in the study (retrospectively registered). The CTRI is the nodal agency of the Indian Council of Medical Research for registration of all clinical, experimental, field intervention and observation studies.

What should community organisations consider when deciding to partner with researchers? A critical reflection on the Zilla Budakattu Girijana Abhivrudhhi Sangha experience in Karnataka, India.

BACKGROUND: Community organisations and community members are increasingly being involved in health research projects worldwide as part of the engagement movement. Achieving deeper forms of community engagement like partnership demands that decision-making power be shared with community partners. However, how can community partners assess if meaningful engagement and shared decision-making will be possible when approached by prospective research partners? In this paper, we explore how community organisations decide to join health research projects when approached by health researchers. METHODS: Case study research was undertaken on a health systems research project in Karnataka, India called Participation for Local Action, which was carried out by local researchers in partnership with the Zilla Budakattu Girijana Abhivrudhhi Sangha, a community development organisation. In-depth interviews were conducted with the researchers, Sangha leaders and field investigators from their community. RESULTS: Thematic analysis identified two main themes - 'context' and 'deciding to engage'. The Sangha's experience offers lessons to other community organisations that can help them when deciding to engage with researchers in terms of what features to look for in research partners and in proposed research projects, what requests to make of prospective research partners, and what sorts of outcomes or partnership agreements to accept. These lessons may be especially applicable in contexts where relationships of trust already exist between partners and where they have the skills to lead data collection and analysis. CONCLUSIONS: We hope that this guidance will help empower community organisations to select good research partners and promote more equitable partnerships between community partners and academic researchers.

Factors associated with inequality in composite index of anthropometric failure between the Paniya and kurichiya tribal communities in wayanad district of Kerala.

BACKGROUND: Tribal children in India bear a higher burden of undernutrition when compared to other communities. However, inequality within tribal communities is under-researched. OBJECTIVES: To examine the factors associated with inequality in undernutrition between Paniya and Kurichiya tribal communities in Wayanad district of Kerala. METHODS: A cross-sectional analytical study was conducted during August to October 2018 among 314 children aged 2-5 years belonging to Paniya (151) and Kurichiya (163) communities. Participants were selected using multistage cluster sampling. Data were collected using structured interview schedule based on household food insecurity access scale; relevant individual, parental, and household factors were ascertained; child nutritional status was assessed based on anthropometric measurements. The composite index of anthropometric failure (CIAF) was used as an aggregate indicator of undernutrition. Statistical analysis was done using Chi-square test and univariate and multivariable logistic regression. RESULTS: There were significant differences in the prevalence of stunting, underweight, and wasting between Paniya (52.3%, 58.9%, and 25.2%, respectively) and Kurichiya (28.2%, 31.1%, and 12.3%, respectively) tribal children. Based on the CIAF, 66.9% and 41.1% of Paniya and Kurichiya children, respectively, were undernourished. Intratribal difference was observed to exist in all three forms of anthropometric failures simultaneously. Significant factors associated with CIAF were community identity, household food insecurity, and maternal early marriage. Significant factor associated with all three forms of undernutrition was maternal experience of domestic violence. CONCLUSION: This study demonstrates the child nutritional inequality within the tribal communities and indicates the need for more focused policies and programs among vulnerable tribal groups to ensure food security and empowerment of women.

Navigating intersectoral collaboration in nutrition programming: implementors' perspectives from Assam, India.

BACKGROUND: There is a growing interest in the use of intersectoral collaborative (ISC) approaches to address complex health-related issues. However, relatively little empirical research exists on the challenges of implementing, fostering and sustaining these approaches. Our study explores the perceptions and experiences of programme implementers regarding the implementation of an ISC approach, focusing on a case study of nutrition programming in Assam, India. METHODS: We conducted qualitative semi-structured face-to-face in-depth interviews with eleven programme implementers from two selected districts of Assam, India. These participants were purposefully sampled to provide a comprehensive understanding of the experiences of implementing intersectoral collaboration. Following the interviews, an inductive thematic analysis was performed on the collected data. RESULTS: The study identified three main themes: operationalisation of ISC in daily practice, facilitators of ISC, and barriers to effective ISC. These were further broken down into six subthemes: defined sectoral mandates, leadership dynamics, interpersonal relationships and engagement, collective vision and oversight, resource allocation, and power dynamics. These findings highlight the complexity of ISC, focusing on the important structural and relational aspects at the macro, meso, and micro levels. Interpersonal relationships and power dynamics among stakeholders substantially influenced ISC formation in both the districts. CONCLUSION: Despite challenges, there is ongoing interest in establishing ISC in nutrition programming, supported by political development agendas. Success relies on clarifying sectoral roles, addressing power dynamics, and engaging stakeholders systematically. Actionable plans with measurable targets are crucial for promoting and sustaining ISC, ensuring positive programme outcomes. The insights from our study provide valuable guidance for global health practitioners and policymakers dealing with similar challenges, emphasising the urgent need for comprehensive research given the lack of universally recognised policies in the realm of ISC in global health practice.

Validation of ToucHb, a non-invasive haemoglobin estimation: Effective for normal ranges, needs improvement for anaemia detection.

Non-invasive methods for haemoglobin estimation hold enormous potential for early detection and treatment of anaemia, especially in limited resource settings. We sought to validate the diagnostic accuracy of ToucHb, a non-invasive haemoglobin estimation device available in the Indian market. We prospectively evaluated the diagnostic performance of the ToucHb device using the Automated complete blood count (CBC) method as the gold standard. Persons referred for haemoglobin estimation to the central laboratory of the government medical college hospital in Mysore, southern India were included in the study. Out Of 140 people approached, 127 gave consent; 65% (n = 82) were female with median age of 37 (IQR 28-45). ToucHB reported median haemoglobin value of 14 g/dL compared to 13.3 g/dL for CBC. Within 1 g/dL and 2 g/dL of CBC, 55.2% (70/127) and 74% (94/127) of ToucHb haemoglobin observations fell, respectively. The Bland-Altman plot showed a mean difference of 3 g/dL in haemoglobin between ToucHb and CBC among those with anaemia. The ToucHb device showed 22.2% sensitivity and 94.5% specificity for anaemia detection. In rural resource-limited settings, point of care non-invasive devices such as ToucHb can improve access and acceptance for anaemia screening. However, ToucHb has showed low sensitivity for anaemia detection and low accuracy at lower haemoglobin values. The utility of the instrument is especially limited in detecting anaemia, while it can estimate haemoglobin accurately among those with haemoglobin is in the normal range. Based on these findings, ToucHb and devices that work on the core technology deployed in ToucHb may be better suited to monitor known haemoglobin level rather than in anaemia screening or detection in primary/ secondary care and community settings.

Practices and outcomes of responsive caregiving on child neurodevelopment and mental health across diverse global populations: a scoping review protocol.

INTRODUCTION: Responsive caregiving (RC) leads to positive outcomes in children, including secure attachment with caregivers, emotional regulation, positive social interactions and cognitive development. Through our scoping review, we aim to summarise the practices and outcomes of RC in diverse caregiver and child populations from 0 to 8 years. METHODS AND ANALYSIS: We will use the Arksey and O'Malley framework and the Joanna Briggs Institute methodology for scoping reviews. We shall present our findings as per the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines for scoping review. Only peer-reviewed, English-language articles from 1982 to 2022 will be included from PubMed, Web of Science, APA PsychInfo, APA PsycArticles, SocINDEX and Google Scholar databases. Reference lists of included articles will also be screened. The search strategy will be developed for each database, and search results will be imported into Rayyan. Screening will be done in two phases: (1) titles and abstracts will be screened by two authors and conflicts will be resolved by mutual discussion between both or by consulting with a senior author; and (2) full-texts of shortlisted studies from the first phase will then be screened using the same inclusion/exclusion criteria. A data extraction form will be developed to collate relevant information from the final list of included articles. This form will be pilot tested on the first 10 papers and iteratively refined prior to data extraction from the remaining articles. Results will be presented in figures, tables and a narrative summary. ETHICS AND DISSEMINATION: No ethics approval needed as the review shall only use already published data. We shall publish the review in an open-access, peer-reviewed journal and disseminate through newsletters, social media pages, and presentations to relevant audiences.

Prevalence of dyslipidemia, hypertension and diabetes among tribal and rural population in a south Indian forested region.

While NCDs are in rise globally, tribal and rural populations residing near to reserve forests with limited exposure to modern lifestyles may bear a unique burden. This study investigates the prevalence and risk factors of hypertension, diabetes, and dyslipidemia among these communities. We conducted a cross-sectional study between 2018 and 2020 in the forest-dwelling population of Chamarajanagar, India. Using multistage stratified sampling based on caste and remoteness, we enrolled 608 participants aged over 18 years, including 259 non-tribal and 349 tribal individuals. Data collection includes the administration of STEPS questionnaire and measurement of fasting blood sugar, lipid levels, and blood pressure. The prevalence of diabetes, hypertension, and dyslipidemia were 4.6%, 28.8%, and 85.7%, respectively, among the study population. We also found abnormal levels of low-density lipoprotein (LDL), high-density lipoprotein (HDL), Triglycerides (TGA), Total cholesterol (TC), and very low-density lipoprotein (VLDL)in 4.9%, 82.4%, 22.7%, 5.8%, and 7.4% of participants, respectively. Significant differences were observed in diabetes, LDL abnormality, TGA abnormality, VLDL abnormality, and TC abnormality, but not in hypertension, dyslipidemia, or HDL abnormality, across the Socio Geographic Discrimination Index. We found a significant difference in diabetes and HDL abnormality, but not in hypertension, dyslipidemia, LDL abnormality, TGA abnormality, TC abnormality, or VLDL abnormality, between tribal and non-tribal populations living in the forest-dwelling area. Waist circumference was a significant independent predictor of diabetes among tribal participants, while wealth index, age, and waist circumference were significant predictors of hypertension. There were no significant predictors for dyslipidemia among tribal participants. Our study suggests that tribal population living in a remote area are at a lower risk of developing diabetes compared to non-tribal populations living in the same geographic area. However, the prevalence of hypertension and dyslipidemia among tribal populations remains high and comparable to that of the general population.

Disproportionate infection, hospitalisation and death from COVID-19 in ethnic minority groups and Indigenous Peoples: an application of the Priority Public Health Conditions analytical framework.

The COVID-19 pandemic has resulted in disproportionate consequences for ethnic minority groups and Indigenous Peoples. We present an application of the Priority Public Health Conditions (PPHC) framework from the World Health Organisation (WHO), to explicitly address COVID-19 and other respiratory viruses of pandemic potential. This application is supported by evidence that ethnic minority groups were more likely to be infected, implying differential exposure (PPHC level two), be more vulnerable to severe disease once infected (PPHC level three) and have poorer health outcomes following infection (PPHC level four). These inequities are driven by various interconnected dimensions of racism, that compounds with socioeconomic context and position (PPHC level one). We show that, for respiratory viruses, it is important to stratify levels of the PPHC framework by infection status and by societal, community, and individual factors to develop optimal interventions to reduce inequity from COVID-19 and future infectious diseases outbreaks.

Ecological countermeasures to prevent pathogen spillover and subsequent pandemics.

Substantial global attention is focused on how to reduce the risk of future pandemics. Reducing this risk requires investment in prevention, preparedness, and response. Although preparedness and response have received significant focus, prevention, especially the prevention of zoonotic spillover, remains largely absent from global conversations. This oversight is due in part to the lack of a clear definition of prevention and lack of guidance on how to achieve it. To address this gap, we elucidate the mechanisms linking environmental change and zoonotic spillover using spillover of viruses from bats as a case study. We identify ecological interventions that can disrupt these spillover mechanisms and propose policy frameworks for their implementation. Recognizing that pandemics originate in ecological systems, we advocate for integrating ecological approaches alongside biomedical approaches in a comprehensive and balanced pandemic prevention strategy.

Social Determinants of Child Undernutrition in Adivasi Population in Northern Kerala: A Study Using Syndemic Framework.

OBJECTIVES: To understand the complex interaction of structural inequalities, co-occurring health conditions, and child undernutrition among the Adivasi population in North Kerala, India. METHODS: A mixed-method approach was employed in this study, which combined a cross-sectional survey and a case study design. A multistage cluster sampling method was used to select 167 children aged 24 to 60 mo from the study population. The mothers of these children were interviewed using a structured questionnaire to assess individual, parental, and household-level factors associated with child undernutrition. Two Paniya settlements, one with a high prevalence of child undernutrition (HPS) and the other with a low prevalence (LPS), were chosen as the primary units of the case study. RESULTS: The study found that the absence of a kitchen garden with fruits and vegetables [adjusted odds ratio (AOR) 2.85; 95% confidence interval (CI): 1.04-7.81] and a history of cough and fever (AOR 2.93; 95% CI: 1.24-6.93) were both associated with a higher risk of undernutrition in children. The case studies revealed that Adivasi children are undernourished due to a complex set of factors that persist throughout their lives, including unequal access to social capital, healthcare, and food security, as well as differences in hygiene practices due to the lack of access to clean water and sanitation. CONCLUSIONS: The findings underscore the need for social interventions to complement the current focus almost entirely on food supplementation programmes. Equitable action on Adivasi child malnutrition requires urgent policy and programmatic attention to social inequalities and access to basic amenities in Adivasi areas.

The role of social vulnerability in improving interventions for neglected zoonotic diseases: The example of Kyasanur Forest Disease in India.

Forest-based communities manage many risks to health and socio-economic welfare including the increasing threat of emerging zoonoses that are expected to disproportionately affect poor and marginalised groups, and further impair their precarious livelihoods, particularly in Low-and-Middle Income (LMIC) settings. Yet, there is a relative dearth of empirical research on the vulnerability and adaptation pathways of poor and marginalised groups facing emerging zoonoses. Drawing on a survey of 229 households and a series of key-informant interviews in the Western Ghats, we examine the factors affecting vulnerability of smallholder and tribal households to Kyasanur Forest Disease (KFD), an often-fatal tick-borne viral haemorrhagic fever endemic in south India. Specifically, we investigate how different socio-demographic and institutional factors interact to shape KFD vulnerability and the strategies employed by households to adapt to disease consequences. Although surveyed households generally perceived KFD as an important health issue in the study region, there was variability in concern about contracting the disease. Overall results showed that poor access to land (AOR = 0.373, 95% CI: 0.152-0.916), being at or below the poverty line (AOR = 0.253, 95% CI: 0.094-0.685) and being headed by an older person (AOR = 1.038, 95% CI: 1.006-1.071) were all significant determinants of perceived KFD vulnerability. Furthermore, KFD vulnerability is also modulated by important extra-household factors including proximity to private hospitals (AOR = 3.281, 95% CI: 1.220-8.820), main roads (AOR = 2.144, 95% CI: 1.215-3.783) and study location (AOR = 0.226, 95% CI: 0.690-0.743). Our findings highlight how homogenous characterisation of smallholder and tribal communities and the 'techno-oriented' approach of existing interventions may further marginalise the most vulnerable and exacerbate existing inequalities. These findings are important for designing context-specific and appropriate health interventions (including the prioritisation of awareness raising, knowledge networks, livelihood diversification) that enhances the resilience of at-risk social groups within the KFD context. More broadly, our findings highlight how a focus on social vulnerability can help national and international health planners improve health interventions and prioritise among diseases with respect to neglected endemic zoonoses.

Health technology assessment implementation in WHO South-East Asia Region: a realist review protocol.

Background: A robust Health Technology Assessment (HTA) framework is crucial to address the rising burden of healthcare costs and to inform decision-making to promote high-quality health systems. This research aims to describe the HTA methods and mechanisms for the successful implementation of HTA in the WHO South-East Asia region, and contextualize the synthesized evidence relevant to Indian settings. Methods: Realist review involves developing a program theory by conducting a systematic search strategy, screening, study selection, data extraction, and data synthesis. A systematic search for literature will be conducted on PubMed (NCBI), EMBASE (Elsevier), Scopus (Elsevier), Web of Science (Clarivate), and ProQuest Central for identifying the methods used for HTA of health technology interventions. Stakeholder consultations will be conducted to develop a program theory following the Context-Mechanism-Outcome configurations (CMOcs) framework. Searches for primary evidence will be conducted iteratively. Data will be extracted and tested against the programme theory. The proposed realist review will be reported as per the Realist and MEta-narrative Evidence Syntheses: Evolving Standards [RAMESES II] guidelines. Conclusions: To our knowledge, there has been no comprehensive review conducted to understand the mechanisms of HTA methods in the WHO South-East Asia region. The findings from the realist review will help us understand the mechanisms through which the HTA could work in WHO South-East Asian countries. We will then contextualize the findings obtained from evidence to Indian settings, based on program theory development through stakeholder consultation. A framework will be developed that can be used by policymakers/HTA experts in India for effective implementation of the same.

Bioactive hyaluronan fragment (hexasaccharide) detects specific hexa-binding proteins in human breast and stomach cancer: possible role in tumorogenesis.

Hyaluronan (HA) is a component of extracellular matrix that influences cell-proliferation, migration, development, regeneration, normal tissue remodeling, tissues undergoing malignancy and tumor cell interaction. The widespread occurrence of HA binding proteins, their involvement in tissue organization and the control of cellular behavior are well documented. The low molecular mass HA fragments can also induce a variety of biological events, including chemokine gene expression, transcription factor expression and angiogenesis. It is believed that these fragments are more potent in cellular activities than high molecular mass HA. In this study, we isolated the various fragments by gel permeation chromatography of hyaluronidase digested HA and characterized by fluoro assisted carbohydrate electrophoresis (FACE) and matrix assisted laser desorption ionization analysis (MALDI). Detection and distribution of cellular receptors in invasive tumor tissues for HA polymer and HA fragments were determined both by Western blot and histochemistry. The study demonstrated the overexpression of HA-hexa binding protein in human tumors of breast and stomach and its involvement in tumorogenesis.

Overcoming structural barriers to sharing power with communities in global health research priority-setting: Lessons from the Participation for Local Action project in Karnataka, India.

Community engagement is gaining prominence in global health research. But communities rarely have a say in the agendas or conduct of the very health research projects that aim to help them. This paper provides new evidence on how to share power in priority-setting in ways that seek to overcome structural constraints created by the funding environment. The five strategies were identified through case study research on the Participation for Local Action project in Karnataka, India. That project was carried out by researchers in partnership with the Zilla Budakattu Girijana Abhivrudhhi Sangha, an indigenous community development organisation representing the Solega people. The paper describes each identified strategy for sharing power in priority-setting, followed by a report of the pitfalls and challenges that arose when implementing it. Thus, the study also demonstrates that even where actions and strategies are used to address power imbalances, pitfalls will arise that need to be navigated. Given those challenges, considerations to reflect upon before employing the identified strategies are suggested. Ultimately, the paper aims to communicate strategies for sharing power during and after priority-setting and lessons on how to implement them effectively that can be used by global health researchers in the current funding environment.
