Background: The inSCALE cluster randomised controlled trial evaluated two interventions, mHealth and Village Health Clubs (VHCs) which aimed to improve Community Health Worker (CHW) treatment for malaria, diarrhoea, and pneumonia within the Integrated Community Case Management programme. Methods: In a cluster randomised trial, 39 sub-counties in Midwest Uganda, covering 3167 CHWs, were randomly allocated to mHealth; VHC or usual care (control) arms. Household surveys captured parent-reported child illness, care seeking and treatment practices. Intention-to-treat analysis estimated the proportion of appropriately treated children with malaria, diarrhoea and pneumonia according to WHO informed national guidelines. Registration: ClinicalTrials.gov (NCT01972321). ResultsBetween April-June 2014, 7679 households were surveyed; 2806 children were found with malaria, diarrhoea or pneumonia symptoms in the last one month. Appropriate treatment was 11% higher in the mHealth compared to the control arm (risk ratio [RR] 1·11, 95% CI 1·02, 1·21; p=0·018). The largest effect was on appropriate treatment for diarrhoea (RR 1·39; 95% CI 0·90, 2·15; p=0·134). The VHC intervention increased appropriate treatment by 9% (RR 1·09; 95% CI 1·01, 1·18; p=0·059), again with largest effect on treatment of diarrhoea (RR 1·56, 95% CI 1·04, 2·34, p=0·030). CHWs provided the highest levels of appropriate treatment compared to other providers. However, differences in appropriate treatment were at health facilities and pharmacies, with CHW appropriate treatment the same across the arms. The rate of CHW attrition in both intervention arms was less than half that of the control arm; adjusted risk difference mHealth arm -4·42% (95% CI -8·54, -0·29, p=0·037) and VHC arm -4·75% (95% CI -8·74, -0·76, p=0·021). Interpretation: Appropriate treatment by CHWs was encouragingly high across arms. The inSCALE mHealth and VHC interventions have the potential to reduce CHW attrition and improve the treatment of sick children, but not through the hypothesised mechanisms of improved CHW utilization and treatment.

Introduction Several countries have adopted integrated community case management (iCCM) as a strategy for improved health service delivery in areas with poor health facility coverage. Early implementation of iCCM is often run by nongovernmental organizations financed by donors through projects. Such projects risk failure to transition into programs run by the local health system upon project closure. Engagement of subnational health authorities such as district health teams (DHTs) is essential for a smooth transition. Methods We used a repeated qualitative study design to assess the readiness of and progress made by DHTs in institutionalizing iCCM into the functions of locally decentralized health systems in 9 western Uganda districts. Readiness data were derived from structured group interviews with DHTs before iCCM policy adoption in 2010 and again in 2015. Progressive institutionalization achievements were assessed through key informant interviews with targeted DHT members and local government district planners in the same areas. Findings In the readiness study, DHTs expressed commitment to institutionalize iCCM into the local health system through the development of district-specific iCCM activity work plans and budgets. The DHTs further suggested that they would implement district-led training, motivation, and supervision of community health workers; procurement of iCCM medicines and supplies; and advocacy activities for inclusion of iCCM indicators into the national health information systems. After iCCM policy adoption, follow-up study data findings showed that iCCM was largely not institutionalized into the local district health system functions. The poor institutionalization was attributed to lack of stewardship on how to transition from externally supported implementation to district-led programming, conflicting guidelines on community distribution of medicines, poor community-level accountability systems, and limited decision-making autonomy at the district level. Conclusion Successful institutionalization of iCCM requires local ownership with increased coordination and cooperation among governmental and nongovernmental actors at both the national and district levels.

Additional file 1: Top down unit costs in 2013 and 2014 of visit (USD) for any illness, children under 5.

Background Globally, nearly half of all deaths among children under the age of 5 years can be attributed to malaria, diarrhoea, and pneumonia. A significant proportion of these deaths occur in sub-Saharan Africa. Despite several programmes implemented in sub-Saharan Africa, the burden of these illnesses remains persistently high. To mobilise resources for such programmes it is necessary to evaluate their costs, costs-effectiveness, and affordability. This study aimed to estimate the provider costs of treating malaria, diarrhoea, and pneumonia among children under the age of 5 years in routine settings at the health facility level in rural Uganda and Mozambique. Methods Service and cost data was collected from health facilities in midwestern Uganda and Inhambane province, Mozambique from private and public health facilities. Financial and economic costs of providing care for childhood illnesses were investigated from the provider perspective by combining a top-down and bottom-up approach to estimate unit costs and annual total costs for different types of visits for these illnesses. All costs were collected in Ugandan shillings and Mozambican meticais. Costs are presented in 2021 US dollars. Results In Uganda, the highest number of outpatient visits were for children with uncomplicated malaria and of inpatient admissions were for respiratory infections, including pneumonia. The highest unit cost for outpatient visits was for pneumonia (and other respiratory infections) and ranged from $0.5 to 2.3, while the highest unit cost for inpatient admissions was for malaria ($19.6). In Mozambique, the highest numbers of outpatient and inpatient admissions visits were for malaria. The highest unit costs were for malaria too, ranging from $2.5 to 4.2 for outpatient visits and $3.8 for inpatient admissions. The greatest contributors to costs in both countries were drugs and diagnostics, followed by staff. Conclusions The findings highlighted the intensive resource use in the treatment of malaria and pneumonia for outpatient and inpatient cases, particularly at higher level health facilities. Timely treatment to prevent severe complications associated with these illnesses can also avoid high costs to health providers, and households.

Background Malaria remains the number one cause of morbidity and mortality in Uganda. In 2009, the United States President’s Malaria Initiative (PMI) funded an indoor residual spraying (IRS) project in 10 mid-northern districts, resulting in marked reductions in malaria prevalence over 5 years, from 62.5 percent to 7.2 percent. When the project ended and IRS withdrawn, malaria prevalence increased exponentially to pre-IRS level of 63 percent in 2016 and was characterized by frequent life-threatening upsurges that were exacerbated by a weak national led malaria surveillance system with delayed and piece meal responses. Malaria Consortium, in collaboration with Nwoya district local government implemented a district led malaria surveillance and response system. This study was conducted to compare the impact of District led and national led surveillance and response systems on overall malaria burden in two sub-counties in Nwoya district, Northern Uganda. Methods The assessment was conducted between week 41 of 2018 and week 10 of 2019 in Anaka and Alero sub counties following the shift from the national to district led malaria surveillance and response system. A district multi-sectoral malaria response taskforce team, known as the District Malaria Surveillance and Response Team (DMSRT), was formed by the Nwoya District Health Team (DHT). The DMSRT was trained and equipped with new surveillance tools for early detection of and response to malaria upsurges within the district, and were mandated to develop a costed district specific malaria response plan. Results All (18) targeted health facilities provided weekly malaria reports and continuously updated the malaria normal channel graphs. There was an overall reduction in weekly new malaria cases from 12.9 in week 41 of 2018 to 6.2 cases in week 10 of 2019. Malaria positivity rates (TPR) for Alero and Anaka sub-counties reduced from 76.0 percent and 69.3 percent at week 42 of 2018 to 28 percent and 30.3 percent, respectively at week 10 of 2019. Conclusions Malaria surveillance and response, with precisely targeted multipronged activities, when led and implemented by local district health authorities is an effective, efficient, and sustainable approach to prevent malaria upsurges and associated morbidity and mortality.

The goal of this study was to characterize the light-dependent regulation of state transitions in gymnosperms. Two species of conifer were examined: eastern white pine (Pinus strobus L.) and white spruce [Picea glauca (Moench) Voss], as well as the angiosperm pumpkin (Cucurbita pepo L. subsp. pepo). Both diurnal time courses in the field and manipulated light experiments in growth chambers were conducted. Results from chlorophyll fluorescence analysis indicated that pumpkin was able to use a larger fraction of absorbed light to drive photochemistry and retain a lower reduction state at a given light intensity relative to the conifers. Results from western blots using anti-phosphothreonine demonstrate that in field conditions, conifers maintained higher light-harvesting complex II (LHCII) phosphorylation than pumpkin; however, this was likely due to a more variable light environment. Manipulated light experiments showed that general patterns of light-dependent LHCII phosphorylation were similar in conifers and pumpkin, with low levels of LHCII phosphorylation occurring in darkness and maximal levels occurring in low light conditions. However, high light-dependent dephosphorylation of LHCIII appears to be regulated differently in conifers, with conifers maintaining phosphorylation of LHCII proteins at higher excitation pressure compared with pumpkin. Additionally, spruce needles maintained relatively high phosphorylation of LHCII even in very high light conditions. Our results suggest that this difference in dephosphorylation of LHCII may be due to differences in the stromal redox status in spruce relative to pine and pumpkin.

BACKGROUND: A key barrier to appropriate treatment for malaria, diarrhoea, and pneumonia (MDP) in children under 5 years of age in low income rural settings is the lack of access to quality health care. The WHO and UNICEF have therefore called for the scale-up of integrated community case management (iCCM) using community health workers (CHWs). The current study assessed access to treatment, out-of-pocket expenditure and the quality of treatment provided in the public and private sectors compared to national guidelines, using data collected in a large representative survey of caregivers of children in 205 villages with iCCM-trained CHWs in mid-Western Uganda. RESULTS: The prevalence of suspected malaria, diarrhoea and suspected pneumonia in the preceding two weeks in 6501 children in the study sample were 45%, 11% and 24% respectively. Twenty percent of children were first taken to a CHW, 56% to a health facility, 14% to other providers and no care was sought for 11%. The CHW was more likely to provide appropriate treatment compared to any other provider or to those not seeking care for children with MDP (RR 1.51, 95% CI 1.42-1.61, p

Leaf rust, caused by Puccinia triticina (Pt), and stripe rust, caused by P. striiformis f. sp. tritici (Pst), are destructive foliar diseases of wheat worldwide. Breeding for disease resistance is the preferred strategy of managing both diseases. The continued emergence of new races of Pt and Pst requires a constant search for new sources of resistance. Here we report a genome-wide association analysis of 567 winter wheat (Triticum aestivum) landrace accessions using the Infinium iSelect 9K wheat SNP array to identify loci associated with seedling resistance to five races of Pt (MDCL, MFPS, THBL, TDBG, and TBDJ) and one race of Pst (PSTv-37) frequently found in the Northern Great Plains of the United States. Mixed linear models identified 65 and eight significant markers associated with leaf rust and stripe rust, respectively. Further, we identified 31 and three QTL associated with resistance to Pt and Pst, respectively. Eleven QTL, identified on chromosomes 3A, 4A, 5A, and 6D, are previously unknown for leaf rust resistance in T. aestivum.
