Thermal Adaptation in Plants: Understanding the Dynamics of Translation Factors and Condensates.

Plants, as sessile organisms, face the imperative challenge of adjusting growth and development with ever-changing environmental conditions. Protein synthesis is the fundamental process enabling growth of all organisms. Since elevated temperature stress poses a substantial threat to protein stability and function, immediate adjustments of protein synthesis rates are necessary to circumvent accumulation of proteotoxic stress and ensure survival. This review provides an overview about the mechanisms that control translation upon high temperature stress in plants compared to yeast and metazoa by modifying components of the translation machinery. Recent research suggests also an important role for cytoplasmic biomolecular condensates, named stress granules in these processes. The current understanding on the role of stress granules in translational regulation and on the molecular processes associated with translation that might occur within stress granules will also be discussed.

Quality of nutritional status assessment and its relationship with the effect of rainfall on childhood stunting: a cross-sectional study in rural Burkina Faso.

OBJECTIVES: In Burkina Faso, one in every four children under 5 years is stunted. Climate change will exacerbate childhood stunting. Strengthening the health system, particularly the quality of nutrition care at primary health facilities, can minimise the adverse climate effect on stunting. Thus, we examined the quality of nutritional status assessment (QoNA) during curative childcare services in primary health facilities in rural Burkina Faso and its relationship with rainfall-induced childhood stunting. STUDY DESIGN: We conducted a cross-sectional analysis using anthropometric, rainfall, and clinical observation data. METHODS: Our dependent variable was the height-for-age z-score (HAZ) of children under 2 years. Our focal climatic measure was mean rainfall deviation (MRD), calculated as the mean of the difference between 30-year monthly household-level rainfall means and the corresponding months for each child from conception to data collection. QoNA was based on the weight, height, general paleness and oedema assessment. We used a mixed-effect multilevel model and analysed heterogeneity by sex and socio-economic status. RESULTS: Among 5027 young (3-23 months) children (mean age 12 ± 6 months), 21% were stunted (HAZ ≤ -2). The mean MRD was 11 ± 4 mm, and the mean QoNA was 2.86 ± 0.99. The proportion of children in low, medium, and high QoNA areas was 10%, 54%, and 36%, respectively. HAZ showed a negative correlation with MRD. Higher QoNA lowered the negative effect of MRD on HAZ (ß = 0.017, P = 0.003, confidence interval = [0.006, 0.029]). Males and children from poor households benefited less from the moderating effect of QoNA. CONCLUSION: Improving the quality of nutrition assessments can supplement existing efforts to reduce the adverse effects of climate change on children's nutritional well-being.

The impact of international health worker migration and recruitment on health systems in source countries: Stakeholder perspectives from Colombia, Indonesia, and Jordan.

INTRODUCTION: To address domestic shortages, high-income countries are increasingly recruiting health workers from low- and middle-income countries. This practice is much debated. Proponents underline benefits of return migration and remittances. Critics point in particular to the risk of brain drain. Empirical evidence supporting either position is yet rare. This study contributes to filling this gap in knowledge by reporting high-level stakeholders' perspectives on health system impacts of international migration in general, and active recruitment of health workers in specific, in Colombia, Indonesia, and Jordan. METHOD: We used a multiple case study methodology, based on qualitative methods integrated with information available in the published literature. RESULTS: All respondents decried a lack of robust and detailed data as a serious challenge in ascertaining their perspectives on impacts of health worker migration. Stakeholders described current emigration levels as not substantially aggravating existing health workforce availability challenges. This is due to the fact that all three countries are faced with health worker unemployment grounded in unwillingness to work in rural areas and/or overproduction of certain cadres. Respondents, however, pleaded against targeting very experienced and specialised individuals. While observing little harm of health worker migration at present, stakeholders also noted few benefits such as brain gain, describing how various barriers to skill enhancement, return, and reintegration into the health system hamper in practice what may be possible in theory. CONCLUSION: Improved availability of data on health worker migration, including their potential return and reintegration into their country of origin's health system, is urgently necessary to understand and continuously monitor costs and benefits in dynamic national and international health labour markets. Our results imply that potential benefits of migration do not come into being automatically, but need in-country supportive policy and programming, such as favourable reintegration policies or programs targeting engagement of the diaspora.

Arabidopsis translation factor eEF1Bγ impacts plant development and is associated with heat-induced cytoplasmic foci.

The important role of translational control for maintenance of proteostasis is well documented in plants, but the exact mechanisms that coordinate translation rates during plant development and stress response are not well understood. In Arabidopsis, the translation elongation complex eEF1B consists of three subunits: eEF1Bα, eEF1Bß, and eEF1Bγ. While eEF1Bα and eEF1Bß have a conserved GDP/GTP exchange function, the function of eEF1Bγ is still unknown. By generating Arabidopsis mutants with strongly reduced eEF1Bγ levels, we revealed its essential role during plant growth and development and analysed its impact on translation. To explore the function of the eEF1B subunits under high temperature stress, we analysed their dynamic localization as green fluorescent protein fusions under control and heat stress conditions. Each of these fusion proteins accumulated in heat-induced cytoplasmic foci and co-localized with the stress granule marker poly(A)-binding protein 8-mCherry. Protein-protein interaction studies and co-expression analyses indicated that eEF1Bß physically interacted with both of the other subunits and promoted their recruitment to cytoplasmic foci. These data provide new insights into the mechanisms allowing for rapid adaptation of translation rates during heat stress response.

How a supply-side intervention can help to increase caesarean section rates in Burkina Faso facilities-Evidence from an interrupted time-series analysis using routine health data.

OBJECTIVES: In Burkina Faso, only 2.1% of women give birth by caesarean section (CS). To improve the use of maternal health services during pregnancy and childbirth, many interventions were implemented during the 2010s including performance-based financing (PBF) and a free maternal health care policy (the gratuité). The objective of this study is to evaluate the impact of a supply-side intervention (PBF) combined with a demand-side intervention (gratuité) on institutional CS rates in Burkina Faso. METHODS: We used routine health data from all the public health facilities in 21 districts (10 that implemented PBF and 11 that did not) from January 2013 to September 2017. We analysed CS rates as the proportion of CS performed out of all facility-based deliveries (FBD) that occurred in the district. We performed an interrupted time series (ITS) analysis to evaluate the impact of PBF alone and then in conjunction with the gratuité on institutional CS rates. RESULTS: CS rates in Burkina Faso increased slightly between January 2013 and September 2017 in all districts. After the introduction of PBF, the increase of CS rates was higher in intervention than in non-intervention districts. However, after the introduction of the gratuité, CS rates decreased in all districts, independently of the PBF intervention. CONCLUSION: In 2017, despite high FBD rates in Burkina Faso as well as the PBF intervention and the gratuité, less than 3% of women who gave birth in a health facility did so by CS. Our study shows that the positive PBF effects were not sustained in a context of user fee exemption.

Improving the readiness and clinical quality of antenatal care - findings from a quasi-experimental evaluation of a performance-based financing scheme in Burkina Faso.

BACKGROUND: While maternal mortality has declined globally, it remains highest in low-income countries. High-quality antenatal care (ANC) can prevent or decrease pregnancy-related complications for mothers and newborns. The implementation of performance-based financing (PBF) schemes in Sub-Saharan Africa to improve primary healthcare provision commonly includes financial indicators linked to ANC service quality indicators. In this study, we examine changes in ANC provision produced by the introduction of a PBF scheme in rural Burkina Faso. METHODS: This study followed a quasi-experimental design with two data collection points comparing effects on ANC service quality between primary health facilities across intervention and control districts based on difference-in-differences estimates. Performance scores were defined using data on structural and process quality of care reflecting key clinical aspects of ANC provision related to screening and prevention pertaining to first and follow-up ANC visits. RESULTS: We found a statistically significant increase in performance scores by 10 percent-points in facilities' readiness to provide ANC services. The clinical care provided to different ANC client groups scored generally low, especially with respect to preventive care measures, we failed to observe any substantial changes in the clinical provision of ANC care attributable to the PBF. CONCLUSION: The observed effect pattern reflects the incentive structure implemented by the scheme, with a stronger focus on structural elements compared with clinical aspects of care. This limited the scheme's overall potential to improve ANC provision at the client level after the observed three-year implementation period. To improve both facility readiness and health worker performance, stronger incentives are needed to increase adherence to clinical standards and patient care outcomes.

PP7L is essential for MAIL1-mediated transposable element silencing and primary root growth.

The two paralogous Arabidopsis genes MAINTENANCE OF MERISTEMS (MAIN) and MAINTENANCE OF MERISTEMS LIKE1 (MAIL1) encode a conserved retrotransposon-related plant mobile domain and are known to be required for silencing of transposable elements (TE) and for primary root development. Loss of function of either MAIN or MAIL1 leads to release of heterochromatic TEs, reduced condensation of pericentromeric heterochromatin, cell death of meristem cells and growth arrest of the primary root soon after germination. Here, we show that they act in one protein complex that also contains the inactive isoform of PROTEIN PHOSPHATASE 7 (PP7), which is named PROTEIN PHOSPHATASE 7-LIKE (PP7L). PP7L was previously shown to be important for chloroplast biogenesis and efficient chloroplast protein synthesis. We show that loss of PP7L function leads to the same root growth phenotype as loss of MAIL1 or MAIN. In addition, pp7l mutants show similar silencing defects. Double mutant analyses confirmed that the three proteins act in the same molecular pathway. The primary root growth arrest, which is associated with cell death of stem cells and their daughter cells, is a consequence of genome instability. Our data demonstrate so far unrecognized functions of an inactive phosphatase isoform in a protein complex that is essential for silencing of heterochromatic elements and for maintenance of genome stability in dividing cells.

Expression Patterns and Functional Characterization of Arabidopsis Galactose Oxidase-Like Genes Suggest Specialized Roles for Galactose Oxidases in Plants.

Galactose oxidases (GalOxs) are well-known enzymes that have been identified in several fungal species and characterized using structural and enzymatic approaches. However, until very recently, almost no information on their biological functions was available. The Arabidopsis (Arabidopsis thaliana) gene ruby particles in mucilage (RUBY) encodes a putative plant GalOx that is required for pectin cross-linking through modification of galactose (Gal) side chains and promotes cell-cell adhesion between seed coat epidermal cells. RUBY is one member of a family of seven putative GalOxs encoded in the Arabidopsis genome. To examine the function(s) of GalOxs in plants, we studied the remaining six galactose oxidase-like (GOXL) proteins. Like RUBY, four of these proteins (GOXL1, GOXL3, GOXL5 and GOXL6) were found to localize primarily to the apoplast, while GOXL2 and GOXL4 were found primarily in the cytoplasm. Complementation and GalOx assay data suggested that GOXL1, GOXL3 and possibly GOXL6 have similar biochemical activity to RUBY, whereas GOXL5 only weakly complemented and GOXL2 and GOXL4 showed no activity. Members of this protein family separated into four distinct clades prior to the divergence of the angiosperms. There have been recent duplications in Brassicaceae resulting in two closely related pairs of genes that have either retained similarity in expression (GOXL1 and GOXL6) or show expression divergence (GOXL3 and RUBY). Mutant phenotypes were not detected when these genes were disrupted, but their expression patterns suggest that these proteins may function in tissues that require mechanical reinforcements in the absence of lignification.

Impact of Performance-Based Financing on effective coverage for curative child health services in Burkina Faso: Evidence from a quasi-experimental design.

OBJECTIVE: To evaluate the impact of Performance-Based Financing (PBF) on effective coverage of child curative health services in primary healthcare facilities in Burkina Faso. METHODS: An impact evaluation of a PBF pilot programme, using an experiment nested within a quasi-experimental design, was carried out in 12 intervention and 12 comparison districts in six regions of Burkina Faso. Across the 24 districts, primary healthcare facilities (537 both at baseline and endline) and households (baseline = 7978 endline = 7898) were surveyed. Within these households, 12 350 and 15 021 under-five-year-olds caretakers were interviewed at baseline and endline respectively. Linking service quality to service utilisation, we used difference-in-differences to estimate the impact of PBF on effective coverage of curative child health services. RESULTS: Our study failed to detect any effect of PBF on effective coverage. Looking specifically into quality of care indicators, we detected a positive effect of PBF on structural elements of quality of care related to general service readiness, but not on the overall facility quality score, capturing both service readiness and the content of childcare. CONCLUSION: The current study makes a unique contribution to PBF literature, as this is the first study assessing PBF impact on effective coverage for curative child health services in low-income settings. The absence of any significant effects of PBF on effective coverage suggests that PBF programmes require a stronger design focus on quality of care elements especially when implemented in a context of free healthcare policy.

Implementation of a performance-based financing scheme in Malawi and resulting externalities on the quality of care of non-incentivized services.

BACKGROUND: Countries in Africa progressively implement performance-based financing schemes to improve the quality of care provided by maternal, newborn and child health services. Beyond its direct effects on service provision, evidence suggests that performance-based financing can also generate positive externalities on service utilization, such as increased use of those services that reached higher quality standards after effective scheme implementation. Little, however, is known about externalities generated within non-incentivized health services, such as positive or negative effects on the quality of services within the continuum of maternal care. METHODS: We explored whether a performance-based financing scheme in Malawi designed to improve the quality of childbirth service provision resulted positive or negative externalities on the quality of non-targeted antenatal care provision. This non-randomized controlled pre-post-test study followed the phased enrolment of facilities into a performance-based financing scheme across four districts over a two-year period. Effects of the scheme were assessed by various composite scores measuring facilities' readiness to provide quality antenatal care, as well as the quality of screening, prevention, and education processes offered during observed antenatal care consultations. RESULTS: Our study did not identify any statistically significant effects on the quality of ANC provision attributable to the implemented performance-based financing scheme. Our findings therefore suggest not only the absence of positive externalities, but also the absence of any negative externalities generated within antenatal care service provision as a result of the scheme implementation in Malawi. CONCLUSIONS: Prior research has shown that the Malawian performance-based financing scheme was sufficiently effective to improve the quality of incentivized childbirth service provision. Our findings further indicate that scheme implementation did not affect the quality of non-incentivized but clinically related antenatal care services. While no positive externalities could be identified, we also did not observe any negative externalities attributable to the scheme's implementation. While performance-based incentives might be successful in improving targeted health care processes, they have limited potential in producing externalities - neither positive nor negative - on the provision quality of related non-incentivized services.

Challenging German physical education teacher educators' health-related beliefs through Cooperative Planning.

Physical education teacher educators' health-related beliefs can impact public health. An interactive knowledge-to-action approach, such as Cooperative Planning, might challenge the health-related beliefs of physical education teacher educators, thus contributing to innovation in teacher education. We investigated what health-related beliefs physical education teacher educators had before a Cooperative Planning intervention, how these developed throughout the intervention and how teacher educators' perceptions of Cooperative Planning can explain the identified changes and continuities. We established two Cooperative Planning groups that included physical education teacher educators (university lecturers and teacher trainers), researchers, study course coordinators and prospective teachers. The data of 13 teacher educators were collected before (t0) and after (t1) the Cooperative Planning using two methods: observations of teaching practice and interviews. The data analysis was based on the following categories: (i) epistemic beliefs about health (e.g. salutogenic understanding), (ii) beliefs about the health topic in physical education (e.g. health-related knowledge and understanding), (iii) beliefs about the health topic in physical education teacher education (e.g. health-related pedagogical content knowledge) and (iv) process-related beliefs about Cooperative Planning. The findings revealed that teacher educators' health-related beliefs were rather stable but could be challenged through a Cooperative Planning intervention. Epistemic beliefs about health remained, whereas more practice-related beliefs about the health topic in physical education and physical education teacher education changed in individual ways. Here, a change in beliefs was more likely when the participants were open to change and when Cooperative Planning offered opportunities to engage in concrete lesson planning.

The health-related beliefs of physical education teacher educators are assumed to play an important role in fostering and implementing the public health agenda. In this article, we report on a Cooperative Planning intervention in which physical education teacher educators (university lecturers and teacher trainers), physical education teacher students, study course coordinators and researchers worked together to develop health-related courses for physical education teacher education. Specifically, we investigated what health-related beliefs teacher educators had before a Cooperative Planning intervention, how these developed throughout the intervention and how teacher educators' opinions of Cooperative Planning can explain how their beliefs changed. Based on interviews and observations, we analysed teacher educators' epistemic beliefs about health, that is, their general understanding of health, their beliefs about the health topic in physical education and physical education teacher education and their process-related beliefs about Cooperative Planning. The findings showed that teacher educators' health-related beliefs were rather stable but could be challenged through Cooperative Planning. Epistemic beliefs about health remained, whereas more practice-related beliefs about the health topic in physical education and physical education teacher education changed in individual ways. A change in beliefs was more likely when the Cooperative Planning participants were open to change and when the Cooperative Planning offered opportunities to engage in concrete lesson planning.

Patterns of healthcare seeking among people reporting chronic conditions in rural sub-Saharan Africa: findings from a population-based study in Burkina Faso.

OBJECTIVE: Non-communicable diseases are rapidly becoming one of the leading causes of morbidity and mortality in sub-Saharan Africa. Yet, little is known about patterns of healthcare seeking among people with chronic conditions in these settings. We aimed to explore determinants of healthcare seeking among people who reported at least one chronic condition in rural Burkina Faso. METHODS: Data were drawn from a cross-sectional population-based survey conducted across 24 districts on 52 562 individuals from March to June 2017. We used multinomial logistic regression to assess factors associated with seeking care at a formal provider (facility-based care) or at an informal provider (home and traditional treatment) compared to no care. RESULTS: 1124 individuals (2% of all respondents) reported at least one chronic condition. Among those, 22.8% reported formal care use, 10.6% informal care use, and 66.6% no care. The presence of other household members reporting a chronic condition (RRR = 0.57, 95%-CI [0.39, 0.82]) was negatively associated with seeking formal care. Wealthier households (RRR = 2.14, 95%-CI [1.26, 3.64]), perceived illness severity (RRR = 3.23, 95%-CI [2.22, 4.70]) and suffering from major chronic conditions (RRR = 1.54, 95%-CI [1.13, 2.11]) were positively associated with seeking formal care. CONCLUSION: Only a minority of individuals with chronic conditions sought formal care, with important differences due to socio-economic status. Policies and interventions aimed at increasing the availability and affordability of services for early detection and management in peripheral settings should be prioritised.

OBJECTIF: Les maladies non transmissibles deviennent rapidement l'une des principales causes de morbidité et de mortalité en Afrique subsaharienne. Pourtant, on en sait peu sur les profils de recherche de soins de santé chez les personnes atteintes de maladies chroniques dans ces milieux. Nous visions à explorer les déterminants de la recherche de soins de santé chez les personnes qui ont déclaré au moins une maladie chronique dans les régions rurales du Burkina Faso. MÉTHODES: Les données ont été tirées d'une enquête transversale de population menée dans 24 districts auprès de 52.562 personnes de mars à juin 2017. Nous avons utilisé une régression logistique multinomiale pour évaluer les facteurs associés à la recherche de soins chez un prestataire formels (soins en établissement) ou chez un prestataire informel (traitement à domicile et traditionnel) par rapport à l'absence de soins. RÉSULTATS: 1.124 personnes (2% de tous les répondants) ont déclaré au moins une maladie chronique. Parmi ceux-ci, 22,8% ont déclaré avoir recours à des soins formels, 10,6% à des soins informels et 66,6% à aucun soin. La présence d'autres membres du ménage déclarant une maladie chronique (RRR = 0,57, IC95%: 0,39, 0,82) était associée négativement à la recherche de soins formels. Les ménages plus riches (RRR = 2,14; IC95%: 1,26-3,64), la sévérité perçue de la maladie (RRR = 3,23 ; IC95%: 2,22-4,70) et souffrir de maladies chroniques majeures (RRR = 1,54 ; IC95%: 1,13-2,11) étaient positivement associés à la recherche de soins formels. CONCLUSION: Seule une minorité de personnes atteintes de maladies chroniques ont recherché des soins formels, avec des différences importantes en raison du statut socioéconomique. Les politiques et interventions visant à accroître la disponibilité et l'accessibilité des services de détection précoce et de prise en charge dans les régions périphériques doivent être prioritaires.

Experiences of psychotherapists working with refugees in Germany: a qualitative study.

BACKGROUND: Despite a high burden of mental health problems among refugees, there is limited knowledge about effective mental health care provision for this group. Although substantial efforts in understanding the complexity of cross-cultural psychotherapy - which in the context of this study we use to refer to therapy with client and therapist of different cultural backgrounds - have been made, there remains a dearth of research exploring barriers for effective cross-cultural psychotherapy. This study aimed at narrowing this gap in knowledge by exploring major challenges encountered by psychotherapists in cross-cultural psychotherapy and strategies which have proven useful in overcoming such challenges. METHODS: We employed a qualitative study design, conducting semi-structured in-depth interviews with 10 purposely selected psychotherapists working with refugees in Germany. Respondents were from varying theoretical background and had varying levels of experience. Data were analyzed using a thematic approach, following a mix of deductive and inductive coding. RESULTS: Respondents reported three main challenges in their cross-cultural practice: different or unrealistic expectations of clients towards what psychotherapy would offer them; challenges grounded in different illness explanatory models; and communication challenges. In dealing with these challenges, respondents recommended psychoeducation to overcome issues related to problematic expectations towards psychotherapy; "imagining the real", identifying "counter magic" and other client-appropriate resources to deal with issues related to clients' foreign illness attributions; and translators in dealing with communication barriers, though the latter not univocally. CONCLUSIONS: Results show that psychotherapy with refugees can be very successful, at least from the psychotherapist perspective, but also poses significant challenges. Our findings underline the importance of developing, testing, and institutionalizing structured and structural approaches to training psychotherapists in cross-cultural therapy at scale, to accommodate the rising mental health care need of refugees as a client group.

Quality of maternal obstetric and neonatal care in low-income countries: development of a composite index.

BACKGROUND: In low-income countries, studies demonstrate greater access and utilization of maternal and neonatal health services, yet mortality rates remain high with poor quality increasingly scrutinized as a potential point of failure in achieving expected goals. Comprehensive measures reflecting the multi-dimensional nature of quality of care could prove useful to quality improvement. However, existing tools often lack a systematic approach reflecting all aspects of quality considered relevant to maternal and newborn care. We aim to address this gap by illustrating the development of a composite index using a step-wise approach to evaluate the quality of maternal obstetric and neonatal healthcare in low-income countries. METHODS: The following steps were employed in creating a composite index: 1) developing a theoretical framework; 2) metric selection; 3) imputation of missing data; 4) initial data analysis 5) normalization 6) weighting and aggregating; 7) uncertainty and sensitivity analysis of resulting composite score; 8) and deconstruction of the index into its components. Based on this approach, we developed a base composite index and tested alternatives by altering the decisions taken at different stages of the construction process to account for missing values, normalization, and aggregation. The resulting single composite scores representing overall maternal obstetric and neonatal healthcare quality were used to create facility rankings and further disaggregated into sub-composites of quality of care. RESULTS: The resulting composite scores varied considerably in absolute values and ranges based on method choice. However, the respective coefficients produced by the Spearman rank correlations comparing facility rankings by method choice showed a high degree of correlation. Differences in method of aggregation had the greatest amount of variation in facility rankings compared to the base case. Z-score standardization most closely aligned with the base case, but limited comparability at disaggregated levels. CONCLUSIONS: This paper illustrates development of a composite index reflecting the multi-dimensional nature of maternal obstetric and neonatal healthcare. We employ a step-wise process applicable to a wide range of obstetric quality of care assessment programs in low-income countries which is adaptable to setting and context. In exploring alternative approaches, certain decisions influencing the interpretation of a given index are highlighted.

Psychological wellbeing in a resource-limited work environment: examining levels and determinants among health workers in rural Malawi.

BACKGROUND: A competent, responsive, and productive health workforce is central to a well-performing health system capable of providing universal access to high-quality care. Ensuring health workers' psychological wellbeing is critical to sustaining their availability and productivity. This is particularly true in heavily constrained health systems in low- and lower-middle-income countries. Research on the issue, however, is scarce. This study aimed to contribute to filling the gap in knowledge by investigating levels of and factors associated with psychological wellbeing of mid-level health workers in Malawi. METHODS: The study relied on a cross-sectional sample of 174 health workers from 33 primary- and secondary-level health facilities in four districts of Malawi. Psychological wellbeing was measured using the WHO-5 Wellbeing Index. Data were analyzed using linear and logistic regression models. RESULTS: Twenty-five percent of respondents had WHO-5 scores indicative of poor psychological wellbeing. Analyses of factors related to psychological wellbeing showed no association with sex, cadre, having dependents, supervision, perceived coworker support, satisfaction with the physical work environment, satisfaction with remuneration, and motivation; a positive association with respondents' satisfaction with interpersonal relationships at work; and a negative association with having received professional training recently. Results were inconclusive in regard to personal relationship status, seniority and responsibility at the health facility, clinical knowledge, perceived competence, perceived supervisor support, satisfaction with job demands, health facility level, data collection year, and exposure to performance-based financing. CONCLUSIONS: The high proportion of health workers with poor wellbeing scores is concerning in light of the general health workforce shortage in Malawi and strong links between wellbeing and work performance. While more research is needed to draw conclusions and provide recommendations as to how to enhance wellbeing, our results underline the importance of considering this as a key concern for human resources for health.

Responding to policy makers' evaluation needs: combining experimental and quasi-experimental approaches to estimate the impact of performance based financing in Burkina Faso.

BACKGROUND: The last two decades have seen a growing recognition of the need to expand the impact evaluation toolbox from an exclusive focus on randomized controlled trials to including quasi-experimental approaches. This appears to be particularly relevant when evaluation complex health interventions embedded in real-life settings often characterized by multiple research interests, limited researcher control, concurrently implemented policies and interventions, and other internal validity-threatening circumstances. To date, however, most studies described in the literature have employed either an exclusive experimental or an exclusive quasi-experimental approach. METHODS: This paper presents the case of a study design exploiting the respective advantages of both approaches by combining experimental and quasi-experimental elements to evaluate the impact of a Performance-Based Financing (PBF) intervention in Burkina Faso. Specifically, the study employed a quasi-experimental design (pretest-posttest with comparison) with a nested experimental component (randomized controlled trial). A difference-in-differences approach was used as the main analytical strategy. DISCUSSION: We aim to illustrate a way to reconcile scientific and pragmatic concerns to generate policy-relevant evidence on the intervention's impact, which is methodologically rigorous in its identification strategy but also considerate of the context within which the intervention took place. In particular, we highlight how we formulated our research questions, ultimately leading our design choices, on the basis of the knowledge needs expressed by the policy and implementing stakeholders. We discuss methodological weaknesses of the design arising from contextual constraints and the accommodation of various interests, and how we worked ex-post to address them to the best extent possible to ensure maximal accuracy and credibility of our findings. We hope that our case may be inspirational for other researchers wishing to undertake research in settings where field circumstances do not appear to be ideal for an impact evaluation.

Factors associated with misreporting in performance-based financing in Burkina Faso: Implications for risk-based verification.

Performance-based financing (PBF) has been piloted in many low- and middle-income countries (LMICs) as a strategy to improve access to and quality of health services. As a key component of PBF, quantity verification is carried out to ensure that reported data matches the actual number of services provided. However, cost concerns have led to a call for risk-based verification. Existing evidence suggests misreporting is associated with factors such as complexity of indicators, high service volume, and accepted error margin. In contrast, evidence on the association of key facility characteristics with misreporting in PBF is scarce. We contributed to filling this gap in knowledge by combining administrative data from a large-scale pilot PBF program in Burkina Faso with data from a health facility assessment in the context of an impact evaluation of the intervention. Our results showed the coexistence of both overreporting and underreporting and that misreporting varied by service indicator and health district. We also found that the number of clinical staff at the facility, the population size in the facility catchment area, and the distance between the facility and the district administration were associated with the probability of misreporting. We recommend further research of these factors in the move towards risk-based verification. In addition, given that our analysis identified relevant associations, but could not explain them, we recommend further qualitative inquiry into verification processes.

Mycenaflavin†A, B, C, and D: Pyrroloquinoline Alkaloids from the Fruiting Bodies of the Mushroom Mycena haematopus.

Four so far unknown pyrroloquinoline alkaloids, yellow mycenaflavins A, B, and C, and the purple mycenaflavin D, have been isolated from the fruiting bodies of Mycena haematopus. The structures of these new alkaloids were elucidated by NMR spectroscopy and HRMS (ESI+ ). The mycenaflavins are structurally related to mycenarubins and haematopodins, which have been previously identified in M. haematopus. However, compared with other known fungal pyrroloquinoline alkaloids, the mycenaflavins contain an additional double bond within the pyrroloquinoline moiety that accounts for the yellow colour of the monomeric mycenaflavins A, B, and C. The purple mycenaflavin D is the first known dimeric pyrroloquinoline alkaloid with a C-C bridge between the two pyrroloquinoline units. Although the minor pyrroloquinoline alkaloid constituent mycenaflavin A exhibits only moderate bioactivity against the soil bacterium Azoarcus tolulyticus, the major pyrroloquinoline alkaloid constituent haematopodin B is similarly active as the antibiotic gentamicin.

Inequities and their determinants in coverage of maternal health services in Burkina Faso.

BACKGROUND: Poor and marginalized segments of society often display the worst health status due to limited access to health enhancing interventions. It follows that in order to enhance the health status of entire populations, inequities in access to health care services need to be addressed as an inherent element of any effort targeting Universal Health Coverage. In line with this observation and the need to generate evidence on the equity status quo in sub-Saharan Africa, we assessed the magnitude of the inequities and their determinants in coverage of maternal health services in Burkina Faso. METHODS: We assessed coverage for three basic maternal care services (at least four antenatal care visits, facility-based delivery, and at least one postnatal care visit) using data from a cross-sectional household survey including a total of 6655 mostly rural, poor women who had completed a pregnancy in the 24 months prior to the survey date. We assessed equity along the dimensions of household wealth, distance to the health facility, and literacy using both simple comparative measures and concentration indices. We also ran hierarchical random effects regression to confirm the presence or absence of inequities due to household wealth, distance, and literacy, while controlling for potential confounders. RESULTS: Coverage of facility based delivery was high (89%), but suboptimal for at least four antenatal care visits (44%) and one postnatal care visit (53%). We detected inequities along the dimensions of household wealth, literacy and distance. Service coverage was higher among the least poor, those who were literate, and those living closer to a health facility. We detected a significant positive association between household wealth and all outcome variables, and a positive association between literacy and facility-based delivery. We detected a negative association between living farther away from the catchment facility and all outcome variables. CONCLUSION: Existing inequities in maternal health services in Burkina Faso are likely going to jeopardize the achievement of Universal Health Coverage. It is important that policy makers continue to strengthen and monitor the implementation of strategies that promote proportionate universalism and forge multi-sectoral approach in dealing with social determinants of inequities in maternal health services coverage.
