Using the social entrepreneurship approach to generate innovative and sustainable malaria diagnosis interventions in Tanzania: a case study

<p>Abstract</p> <p>Background</p> <p>There have been a number of interventions to date aimed at improving malaria diagnostic accuracy in sub-Saharan Africa. Yet, limited success is often reported for a number of reasons, especially in rural settings. This paper seeks to provide a framework for applied research aimed to improve malaria diagnosis using a combination of the established methods, participatory action research and social entrepreneurship.</p> <p>Methods</p> <p>This case study introduces the idea of using the social entrepreneurship approach (SEA) to create innovative and sustainable applied health research outcomes. The following key elements define the SEA: (1) identifying a locally relevant research topic and plan, (2) recognizing the importance of international multi-disciplinary teams and the incorporation of local knowledge, (3) engaging in a process of continuous innovation, adaptation and learning, (4) remaining motivated and determined to achieve sustainable long-term research outcomes and, (5) sharing and transferring ownership of the project with the international and local partner.</p> <p>Evaluation</p> <p>The SEA approach has a strong emphasis on innovation lead by local stakeholders. In this case, innovation resulted in a unique holistic research program aimed at understanding patient, laboratory and physician influences on accurate diagnosis of malaria. An evaluation of milestones for each SEA element revealed that the success of one element is intricately related to the success of other elements.</p> <p>Conclusions</p> <p>The SEA will provide an additional framework for researchers and local stakeholders that promotes innovation and adaptability. This approach will facilitate the development of new ideas, strategies and approaches to understand how health issues, such as malaria, affect vulnerable communities.</p

Cross-Sectional Study Protocol for the COVID-19 Impact Survey of Mothers and Their 7–11 Year Old Children in Alberta, Canada

Objectives: Our aim is to understand the effect of the COVID-19 pandemic on families who have been followed longitudinally in two cohorts studied in Alberta, Canada. We will examine household infections during the COVID-19 pandemic, financial impact, domestic violence, substance use, child school and daily life and relationships in the home. We will identify risk and protective factors for maternal mental health outcomes using longitudinal data that can inform policy and government resource allocation in future disasters.Methods: Mothers who are currently participating in two longitudinal studies, Alberta Pregnancy Outcomes and Nutrition (APrON; N = 1,800) and All Our Families (AOF: N = 2,534) were eligible to participate. Mothers were invited to complete the baseline COVID-19 Impact Survey (20–30 min) within 4 months of March 15, 2020, which was when the province of Alberta, Canada, implemented school closures and physical-distancing measures to prevent the spread of COVID-19. Mothers were asked to report on their own, their child's and their family's functioning. Mothers were re-surveyed at 6 months after completion of the initial COVID-19 Impact Survey, and will be re-surveyed again at 12 months.Results: Responses from participants in both cohorts will be examined in harmonized analyses as well as separately. Descriptive, multivariable analysis will be undertaken to examine risk and resiliency over time and factors that predict mental health and well-being.Conclusions: This study will provide timely information on the impact of COVID-19 for Albertan families. It will identify risk and protective factors for mental health and well-being among contemporary urban families supported by a publicly funded health care system to inform allocation of resources to support those most vulnerable during a global pandemic

Symptom-based stratification of patients with primary Sjögren's syndrome: multi-dimensional characterisation of international observational cohorts and reanalyses of randomised clinical trials

Background Heterogeneity is a major obstacle to developing effective treatments for patients with primary Sjögren's syndrome. We aimed to develop a robust method for stratification, exploiting heterogeneity in patient-reported symptoms, and to relate these differences to pathobiology and therapeutic response. Methods We did hierarchical cluster analysis using five common symptoms associated with primary Sjögren's syndrome (pain, fatigue, dryness, anxiety, and depression), followed by multinomial logistic regression to identify subgroups in the UK Primary Sjögren's Syndrome Registry (UKPSSR). We assessed clinical and biological differences between these subgroups, including transcriptional differences in peripheral blood. Patients from two independent validation cohorts in Norway and France were used to confirm patient stratification. Data from two phase 3 clinical trials were similarly stratified to assess the differences between subgroups in treatment response to hydroxychloroquine and rituximab. Findings In the UKPSSR cohort (n=608), we identified four subgroups: Low symptom burden (LSB), high symptom burden (HSB), dryness dominant with fatigue (DDF), and pain dominant with fatigue (PDF). Significant differences in peripheral blood lymphocyte counts, anti-SSA and anti-SSB antibody positivity, as well as serum IgG, κ-free light chain, β2-microglobulin, and CXCL13 concentrations were observed between these subgroups, along with differentially expressed transcriptomic modules in peripheral blood. Similar findings were observed in the independent validation cohorts (n=396). Reanalysis of trial data stratifying patients into these subgroups suggested a treatment effect with hydroxychloroquine in the HSB subgroup and with rituximab in the DDF subgroup compared with placebo. Interpretation Stratification on the basis of patient-reported symptoms of patients with primary Sjögren's syndrome revealed distinct pathobiological endotypes with distinct responses to immunomodulatory treatments. Our data have important implications for clinical management, trial design, and therapeutic development. Similar stratification approaches might be useful for patients with other chronic immune-mediated diseases.

Para-infectious brain injury in COVID-19 persists at follow-up despite attenuated cytokine and autoantibody responses

To understand neurological complications of COVID-19 better both acutely and for recovery, we measured markers of brain injury, inflammatory mediators, and autoantibodies in 203 hospitalised participants; 111 with acute sera (1–11 days post-admission) and 92 convalescent sera (56 with COVID-19-associated neurological diagnoses). Here we show that compared to 60 uninfected controls, tTau, GFAP, NfL, and UCH-L1 are increased with COVID-19 infection at acute timepoints and NfL and GFAP are significantly higher in participants with neurological complications. Inflammatory mediators (IL-6, IL-12p40, HGF, M-CSF, CCL2, and IL-1RA) are associated with both altered consciousness and markers of brain injury. Autoantibodies are more common in COVID-19 than controls and some (including against MYL7, UCH-L1, and GRIN3B) are more frequent with altered consciousness. Additionally, convalescent participants with neurological complications show elevated GFAP and NfL, unrelated to attenuated systemic inflammatory mediators and to autoantibody responses. Overall, neurological complications of COVID-19 are associated with evidence of neuroglial injury in both acute and late disease and these correlate with dysregulated innate and adaptive immune responses acutely

Social Support in a Pregnant and Postnatal Population

Background: Social support, in the form of emotional, informational and tangible resources provided by friends and family is beneficial for health. Social support in pregnancy and the postpartum period is also thought to improve birth outcomes and maternal mental health. However, questions remain as to what type of support is important and for which outcomes. In addition, little is known about patterns of support over time. Methods: A systematic review was conducted to determine the association between low social support and preterm birth. Data from the All Our Families cohort (n=3200) was used for the second two projects This cohort recruited women in pregnancy and followed them to 1 year postpartum, measuring demographic, psychosocial and birth outcome information. Multivariable binomial regression was used to estimate the impact of social support during pregnancy and in the early postpartum period on subsequent mental health symptoms. Group based trajectory modeling was used to determine patterns of support from pregnancy to four months postpartum, followed by multinomial regression to determine characteristics associated with different patterns of support. Results: The systematic review found no direct association between social support and preterm birth, however low social support was associated with preterm birth among women experiencing high stress. The second analysis revealed elevated risk of subsequent depression and anxiety symptoms among women with low support, across various levels of previous mental health risk. Finally, the trajectories analysis showed stable support among 98% of women. Stable high support (60% of women) was associated with higher income. Conclusion: Social support can impact both birth outcomes and maternal mental health, and is relatively stable for most women during pregnancy and postpartum. Interventions to improve support will have a larger absolute benefit for women who may be vulnerable due to previous mental health challenges. More research is needed to understand how to influence conditions that will allow women to develop and maintain strong support networks.

“I really wanted to be able to contribute something”: understanding student motivations to create meaningful global health experiences

Background: Global health is an area of increasing interest among health professionals, students and educators. This study aims to explore students’ motivations and experiences with an undergraduate global health research program in low and middle-income countries and to assess student learning and areas for program improvement. Methods: All students participating in the Global Health Research Program at the University of Calgary in the summer of 2009 were asked to participate in the study (n=11). In-depth interviews were conducted with students prior to departure and upon their return. Discourse analysis was used to identify interpretive repertoires and to determine how the use of repertoires improves our understanding of students’ experiences. Results: Prior to departure, students were highly motivated to "give back" to host communities.  Upon return, students felt that their experience had been more about "building relationships" with others than individual contributions to hosts. Discussion: Students' altruistic motivations dominated the discourse, and most students incorporated core concepts from a preparation course only after their international experience.  Extensive preparation, supervision and follow-up support can mitigate many of the risks of short-term global health experiences while providing a safe opportunity for significant learning

Caring for pregnant refugee women in a turbulent policy landscape: perspectives of health care professionals in Calgary, Alberta

Abstract Background Female refugees can be a vulnerable population, often having suffered through traumatic events that pose risks to their health, especially during pregnancy. Pregnancy can be an entry point into the health care system, providing health care professionals the opportunity to gain women’s trust, connect refugees with resources, and optimize the health of mother and child. Policies surrounding the provision and funding of health care services to refugees can impact access to and quality of care. The aim of our study was to understand the experiences of health care professionals caring for pregnant refugee women in Calgary, AB, taking into consideration recent contextual changes to the refugee landscape in Canada. Methods We conducted ten semi-structured interviews with health care professionals who provided regular care for pregnant refugee women at a refugee health clinic and major hospital in Calgary, Alberta. Interviews were recorded, transcribed, and analyzed using an interpretive description methodology. Results Health care providers described several barriers when caring for pregnant refugees, including language barriers, difficulty navigating the health care system, and cultural barriers such as managing traditional gender dynamics, only wanting a female provider and differences in medical practices. Providers managed these barriers through strategies including using a team-based approach to care, coordinating the patient’s care with other services, and addressing both the medical and social needs of the patient. The federal funding cuts added additional challenges, as many refugees were left without adequate health coverage and the system was complicated to understand. Health care providers developed creative strategies to maximize coverage for their patients including paying out of pocket or relying on donations to care for uninsured refugees. Finally, the recent Syrian refugee influx has increased the demand on service providers and further strained already limited resources. Conclusion Health care providers caring for pregnant refugee women faced complex cultural and system-level barriers, and used multiple strategies to address these barriers. Additional system strains add extra pressure on health care professionals, requiring them to quickly adjust and accommodate for new demands

Longitudinal Predictors of Self-Regulation at School Entry: Findings from the All Our Families Cohort

Self-regulation is the ability to manage emotions, modulate behaviors, and focus attention. This critical skill begins to develop in infancy, improves substantially in early childhood and continues through adolescence, and has been linked to long-term health and well-being. The objectives of this study were to determine risk factors and moderators associated with the three elements of self-regulation (i.e., inattention, emotional control, or behavioral control) as well as overall self-regulation, among children at age 5. Participants were mother&ndash;child dyads from the All Our Families study (n = 1644). Self-regulation was assessed at age 5. Risk factors included income, maternal mental health, child sex, and screen time, and potential moderation by parenting and childcare. Adjusted odds ratios of children being at risk for poor self were estimated using multivariable logistic regression. Twenty-one percent of children had poor self-regulation skills. Risk factors for poor self-regulation included lower income, maternal mental health difficulties, and male sex. Childcare and poor parenting did not moderate these associations and hostile and ineffective parenting was independently associated with poor self-regulation. Excess screen time (&gt;1 h per day) was associated with poor self-regulation. Self-regulation involves a complex and overlapping set of skills and risk factors that operate differently on different elements. Parenting and participation in childcare do not appear to moderate the associations between lower income, maternal mental health, male sex, and screen time with child self-regulation
