Introduction: Despite significant progress over past decades, neonatal and infant morbidity and mortality remain unacceptably high in Ethiopia. Simple interventions have been shown to improve the health of children and reduce mortality. These include promotion of exclusive breast feeding for the first 6 months of life, immunisation and utilisation of available newborn healthcare services, which are proven to improve newborn survival. This study aims to determine the impact of a behaviour change intervention that partners Orthodox priests with volunteer community health workers, known in Ethiopia as the Health Development Army and trains them to conduct newborn health outreach to improve care seeking, uptake of key interventions and identification of sick infants., Methods: The study designed is a community-randomised trial conducted in the Central Gondar area. The behaviour change intervention pairs trained Orthodox priests with members of the Health Development Army to conduct community health outreach by identifying near-term pregnant women in their communities and educating them on the topics of exclusive breast feeding, immunisation, nutrition and uptake of available child healthcare services. The evaluation of the intervention will enrol up to 150 newborn-mother pairs from communities receiving the behaviour change intervention and another 150 pairs enrolled from control communities. The quantitative analysis will be done by comparing data between the intervention and control groups related to breast feeding, anthropometry, immunisation status and uptake of child health services. The primary outcomes are exclusive breastfeeding through 6 months, mid-upper arm circumference, completion of vaccinations and infant hospitalisation., Ethics and Dissemination: Ethical approval has been obtained from the University of Washington (STUDY00006942) and the University of Gondar (No.V/P/RCS/05/2523/2019) Institutional Review Boards. Oral consent was obtained for the formative study, whereas written consent (or witnessed thumbprint) will be obtained from all enrolled mothers. Results will be communicated to community members, relevant government agencies and other stakeholders., Trial Registration Number: NCT05111899., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Background: Podoconiosis is a progressive and debilitating form of tropical lymphoedema endemic to Rwanda. Although the physical and psychological consequences are well known, few studies have evaluated the financial burden of podoconiosis., Methods: This cross-sectional, quantitative study aimed to characterize direct treatment costs and impacts on annual earnings among individuals living with podoconiosis. Participants from two highly endemic districts were invited to complete a survey focused on health-seeking history, insurance status, out-of-pocket costs and income changes. Direct treatment costs included medical expenditures (consultation, diagnostics, medication) and non-medical expenditures (food, transportation, accommodation)., Results: Overall, 226 adults (≥18 y of age) diagnosed with podoconiosis participated. Most had access to community-based health insurance (91.6%) but were unable to work (71.7%). Respondents sought care from health centres/posts (61.9%), hospitals (25.1%), traditional healers (5.8%) and/or community health workers (4.0%). On average, study participants paid US$32.50 (range US$0-779.23) annually, or 11.7% of their household salary, on podoconiosis treatments., Conclusions: This study demonstrates the significant financial burden of podoconiosis on individuals and their communities. Increased attention on integrating podoconiosis management into primary care systems and testing cost-effective solutions is needed to protect those who are most vulnerable., (© The Author(s) 2024.

Background: Snakebite envenoming (SBE) is a potentially life-threatening event that can lead to severe physical, mental, and economic hardships, particularly in under-resourced regions like sub-Saharan Africa. In Rwanda, there have been no epidemiological assessments of SBE to guide the Ministry of Health in its efforts to reduce the burden. This study had two main objectives: first, to estimate the incidence of snakebites across districts, and second, to describe formal versus informal healthcare seeking behaviors among snakebite victims in Eastern Province, Rwanda in 2020., Methodology: This cross-sectional study utilized a cluster sampling approach, involving Community Health Workers (CHWs) who recorded snakebite cases across seven districts. The descriptive analysis considered sampling weights, and healthcare seeking behavior was assessed based on the type of care sought as the first point of treatment., Findings: The study surveyed 390,546 individuals across 763 villages and estimated a provincial annual incidence rate of 4.3 cases per 1,000 individuals. Incidence estimates ranged from 1.1 cases per 1,000 in Nyagatare to 9.1 cases per 1,000 individuals in Bugesera and Ngoma districts. Among the 2,545 cases recorded by CHWs, three resulted in deaths. Regarding healthcare-seeking behavior, 13% of snakebite victims (143 out of 1,098) initially consulted formal care providers (CHWs, health post/center, or hospital), while 87% sought informal care (family/friends, pharmacist, or traditional healer). Approximately half of the victims (583, 53.1%) reported severe symptoms. Unsafe practices included skin cutting/burning, tourniquet application, use of black stones, and venom extraction; only 24 cases (2.2%) received anti-venom., Conclusions: This large-scale community-based assessment highlights variations in snakebite incidence between districts and confirms frequent involvement of traditional healers in management. Improving access to anti-venom and community education on the risks of ineffective practices, along with timely use of formal healthcare, are crucial. Collaboration between healthcare providers, traditional healers, community leaders, and policymakers is essential to implement targeted interventions for enhancing snakebite prevention and management strategies., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Hakizimana et al.

Introduction: Child mortality rates remain high in sub-Saharan Africa, including Ethiopia. We are conducting a cluster randomised control trial in the Gondar zone of the Amhara region to determine the impact of pairing Orthodox priests with community health workers, known locally as the Health Development Army (HDA), on newborns' nutritional status, early illness identification and treatment, and vaccination completeness.Ensuring intervention efficacy with scientific rigour is essential, but there are often delays in adopting evidence into policy and programmes. Here, we present a protocol for conducting parallel implementation research alongside an efficacy study to understand intervention implementability and scalability. This will help develop a scale-up strategy for effective elements of the intervention to ensure rapid implementation at scale., Methods and Analysis: We will conduct a stakeholder analysis of key implementation stakeholders and readiness surveys to assess their readiness to scale up the intervention. We will conduct semistructured interviews and focus group discussions with stakeholders, including HDA members, health workers, Orthodox priests, and caregivers, to determine the core intervention elements that need to be scaled, barriers and facilitators to scaling up the intervention in diverse sociocultural settings, as well as the human and technical requirements for national and regional implementation. Finally, to determine the financial resources necessary for sustaining and scaling the intervention, we will conduct activity-based costing to estimate implementation costs from the provider's perspective., Ethics and Dissemination: The study received approval from the University of Gondar Institutional Review Board (approval no: VP/RTT/05/1030/2022) and the University of Washington Human Subjects Division (approval no: STUDY00015369). Participants will consent to participate. Results will be disseminated through workshops with stakeholders, local community meetings, presentations at local and international conferences, and journal publications. The study will provide evidence for factors to consider in developing a scale-up strategy to integrate the intervention into routine health system practices., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2023.

Snakebite envenomation (SBE) is endemic to sub-Saharan Africa and generally over-represented in rural, remote, and impoverished agricultural communities. While poverty is an established risk factor, little research has been done to investigate the economic consequences of SBE. This cross-sectional, quantitative study aimed to measure out-of-pocket spending and lost income when a household member was bitten by a snake. In 2020, 732 snakebite survivors from Eastern Province (Rwanda) agreed to complete a survey administered by telephone. The survey focused on participant demographics, income, direct medical and non-medical costs, care-seeking decisions, and lost work during convalescence. Our results suggested that patients incurred the highest mean expenses when they sought care from hospitals (11 307 RWF or 12 USD) or traditional healers (5 836 RWF or 6 USD) but that the highest maximum cost was incurred from traditional healers (300 000 RWF or 313 USD). Across all victims, the total amount paid to traditional healers (3.4 million RWF or 3 537 USD) was 4.7 times higher than all other care providers combined. On average, families lost 111 814 RWF (117 USD) per snakebite in direct treatment costs and indirect productivity losses. Many victims sought care from traditional healers despite being eligible for free medical care. Altogether, this study serves as a reminder of the serious physical and financial consequences associated with SBE and provides justification for new investments into SBE prevention and care., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Schurer et al.

Background: Rwanda has achieved impressive reductions in malaria morbidity and mortality over the past two decades. However, the disruption of essential services due to the current Covid-19 pandemic can lead to a reversal of these gains in malaria control unless targeted, evidence-based interventions are implemented to mitigate the impact of the pandemic. The extent to which malaria services have been disrupted has not been fully characterized. This study was conducted to assess the impact of Covid-19 on malaria services in Rwanda., Methods: A mixed-methods study was conducted in three purposively selected districts in Rwanda. The quantitative data included malaria aggregated data reported at the health facility level and the community level. The data included the number of malaria tests, uncomplicated malaria cases, severe malaria cases, and malaria deaths. The qualitative data were collected using focus group discussions with community members and community health workers, as well as in-depth interviews with health care providers and staff working in the malaria programme. Interrupted time series analysis was conducted to compare changes in malaria presentations between the pre-Covid-19 period (January 2019 to February 2020) and Covid-19 period (from March 2020 to November 2020). The constant comparative method was used in qualitative thematic analysis., Results: Compared to the pre-Covid-19 period, there was a monthly reduction in patients tested in health facilities of 4.32 per 1000 population and a monthly increase in patients tested in the community of 2.38 per 1000 population during the Covid-19 period. There was no change in the overall presentation rate for uncomplicated malaria. The was a monthly reduction in the proportion of severe malaria of 5.47 per 100,000 malaria cases. Additionally, although healthcare providers continued to provide malaria services, they were fearful that this would expose them and their families to Covid-19. Covid-19 mitigation measures limited the availability of transportation options for the community to seek care in health facilities and delayed the implementation of some key malaria interventions. The focus on Covid-19-related communication also reduced the amount of health information for other diseases provided to community members., Conclusion: The Covid-19 pandemic resulted in patients increasingly seeking care in the community and poses challenges to maintaining delivery of malaria services in Rwanda. Interventions to mitigate these challenges should focus on strengthening programming for the community and home-based care models and integrating malaria messages into Covid-19-related communication. Additionally, implementation of the interrupted interventions should be timed and overlap with the malaria transmission season to mitigate Covid-19 consequences on malaria., (© 2022. The Author(s).)

Paleoclimate reconstructions have enhanced our understanding of how past climates have shaped present-day biodiversity. We hypothesize that the geographic extent of Pleistocene forest refugia and suitable habitat fluctuated significantly in time during the late Quaternary for chimpanzees (Pan troglodytes). Using bioclimatic variables representing monthly temperature and precipitation estimates, past human population density data, and an extensive database of georeferenced presence points, we built a model of changing habitat suitability for chimpanzees at fine spatio-temporal scales dating back to the Last Interglacial (120,000 BP). Our models cover a spatial resolution of 0.0467° (approximately 5.19 km 2 grid cells) and a temporal resolution of between 1000 and 4000 years. Using our model, we mapped habitat stability over time using three approaches, comparing our modeled stability estimates to existing knowledge of Afrotropical refugia, as well as contemporary patterns of major keystone tropical food resources used by chimpanzees, figs (Moraceae), and palms (Arecacae). Results show habitat stability congruent with known glacial refugia across Africa, suggesting their extents may have been underestimated for chimpanzees, with potentially up to approximately 60,000 km 2 of previously unrecognized glacial refugia. The refugia we highlight coincide with higher species richness for figs and palms. Our results provide spatio-temporally explicit insights into the role of refugia across the chimpanzee range, forming the empirical foundation for developing and testing hypotheses about behavioral, ecological, and genetic diversity with additional data. This methodology can be applied to other species and geographic areas when sufficient data are available., (© 2021 The Authors. American Journal of Primatology published by Wiley Periodicals LLC.)

Tropical forests store 40-50 per cent of terrestrial vegetation carbon 1 . However, spatial variations in aboveground live tree biomass carbon (AGC) stocks remain poorly understood, in particular in tropical montane forests 2 . Owing to climatic and soil changes with increasing elevation 3 , AGC stocks are lower in tropical montane forests compared with lowland forests 2 . Here we assemble and analyse a dataset of structurally intact old-growth forests (AfriMont) spanning 44 montane sites in 12 African countries. We find that montane sites in the AfriMont plot network have a mean AGC stock of 149.4 megagrams of carbon per hectare (95% confidence interval 137.1-164.2), which is comparable to lowland forests in the African Tropical Rainforest Observation Network 4 and about 70 per cent and 32 per cent higher than averages from plot networks in montane 2,5,6 and lowland 7 forests in the Neotropics, respectively. Notably, our results are two-thirds higher than the Intergovernmental Panel on Climate Change default values for these forests in Africa 8 . We find that the low stem density and high abundance of large trees of African lowland forests 4 is mirrored in the montane forests sampled. This carbon store is endangered: we estimate that 0.8 million hectares of old-growth African montane forest have been lost since 2000. We provide country-specific montane forest AGC stock estimates modelled from our plot network to help to guide forest conservation and reforestation interventions. Our findings highlight the need for conserving these biodiverse 9,10 and carbon-rich ecosystems., (© 2021. The Author(s), under exclusive licence to Springer Nature Limited.)

Background: Anemia among Women of Reproductive Age (WRA) continues to be among the major public health problems in many developing countries, including Rwanda, where it increased in prevalence between the 2015 and 2010 Rwanda Demographic and Health Survey (RDHS) reports. A thorough understanding of its risk factors is necessary to design better interventions. However, to the best of our knowledge, no study has been conducted in Rwanda on a nationally representative sample to assess factors associated with anemia among WRA. Accordingly, this study was conducted to address such gap., Methods: A quantitative, cross-sectional study was conducted using data from the RDHS 2014-2015. The study population consisted of 6680 WRA who were tested for anemia during the survey. Anemia was defined as having a hemoglobin level equal to or below 10.9 g/dl for a pregnant woman, and hemoglobin level equal to or below 11.9 g/dl for a non-pregnant woman. Pearson's chi-squared test and multiple logistic regression were conducted for bivariate and multivariable analysis, respectively., Results: The prevalence of anemia among WRA was 19.2% (95% CI: 18.0-20.5). Four factors were found to be associated with lower odds of anemia, including being obese (OR: 0.61, 95% CI: 0.40-0.91), being in the rich category (OR: 0.74, 95% CI: 0.63-0.87), sleeping under a mosquito net (OR: 0.85, 95% CI: 0.74-0.98), and using hormonal contraceptives (OR: 0.61, 95% CI: 0.50-0.73). Five factors were associated with higher odds of anemia, including being underweight (OR: 1.39, 95% CI: 1.09-1.78), using an intrauterine device (OR: 1.98, 95% CI: 1.05-3.75), being separated or widowed (OR: 1.35, 95% CI: 1.09-1.67), and living in the Southern province (OR: 1.45, 95% CI: 1.11-1.89) or in the Eastern province (OR: 1.41, 95% CI: 1.06-1.88)., Conclusion: Anemia continues to pose public health challenges; novel public health interventions should consider geographic variations in anemia risk, seek to improve women's economic statuses, and strengthen iron supplementation especially for Intrauterine device users. Additionally, given the association between anemia and malaria, interventions to prevent malaria should be enhanced.

Background: Artemisinin-based combination therapies (ACTs) have proven highly effective in reducing malaria morbidity in sub-Saharan Africa. Artemether-lumefantrine (AL) was introduced in 2005 as a first-line ACT for the treatment of uncomplicated malaria in Rwanda. Monitoring the therapeutic efficacy of ACTs is necessary to ensure effective malaria case management., Methods: A comparative study on the efficacy of AL and dihydroartemisinin-piperaquine (DHP) was conducted in two sites, Masaka and Ruhuha, between September 2013 and December 2015. Clinical and parasitological responses were assessed at days 28 and 42., Results: A total of 534 children were treated with AL (n=267) or DHP (n=267). After polymerase chain reaction (PCR) adjustment, 98.3% and 98.9% of children in the AL and DHP arms, respectively, achieved an adequate clinical and parasitological response (ACPR) at day 28. At day 42, PCR-adjusted ACPR proportions were 97.3% and 98.4% for AL and DHP, respectively. PCR-adjusted ACPR was 99% for both drugs at days 28 and 42 in Ruhuha. The PCR-adjusted ACPR proportions in Masaka were 97.3% for AL and 98.5% for DHP at day 28 and 95.2% for AL and 97.5% for DHP at day 42., Conclusions: AL remains efficacious in Rwanda 10 y after its adoption. The probability of new infections occurring among patients in the DHP arm was significantly lower than those in the AL arm. DHP also demonstrated a greater post-treatment prophylactic effect against new infections compared with AL., (© The Author(s) 2019.

Echinococcus multilocularis is a zoonotic cestode of canid definitive hosts that is emerging as a parasite of medical and veterinary concern in regions of North America, Europe and Asia. Infection with the metacestode stage (alveolar echinococcosis - AE) is life-threatening, especially for patients who reside in low resource countries and lack access to modern diagnostic tests and treatments. The overall objectives of this One Health review were to systematically describe the diagnostic tests currently employed in endemic countries to detect E. multilocularis in people, canids and the environment, and to report the test characteristics of new diagnostic techniques for population surveillance. In this systematic review of English and Chinese language databases, we identified 92 primary records of E. multilocularis surveillance in canids (N = 75), humans (N = 20) and/or the environment (food, soil; N = 3) and 12 grey literature records that reported E. multilocularis surveillance or health systems protocols between 2008 and 2018. Surveillance for E. multilocularis was conducted using a broad range of combined morphological, molecular, immunological and imaging techniques. Nine studies reporting diagnostic evaluations for cestode or metacestode detection were identified, including studies on copro-antigen ELISA, copro-PCR, intestinal examination, Western Blot, magnetic capture RT-PCR and immunochromatography. Our dataset includes prevalence estimates for E. multilocularis in canids, people, or environment in 27 of the 43 endemic countries and reports data gaps in surveillance, laboratory methods, and diagnostic sensitivity. International consensus on gold standard diagnostic techniques and harmonization of human, canid and environmental surveillance data across political boundaries are needed to comprehensively assess the global burden and distribution of this parasite., (© 2019 The Authors.)

Background: In response to a resurgence of malaria in Rwanda, home-based management (HBM) was expanded to enable community-health workers (CHWs) to provide malaria treatment to patients of all ages. We assessed the effect of the expanded HBM program on malaria case presentations at health facilities., Methods: Services provided by CHWs and health facility presentations among individuals >5 y of age were considered. Presentations to CHWs were analyzed descriptively to assess acceptability and segmented regression modeling using facility-level data was employed to compare changes between the pre- and postintervention periods for intervention and control districts., Results: Individuals >5 y of age readily accessed malaria diagnosis and treatment services from CHWs. Severe and uncomplicated malaria increased in the postintervention period for both the intervention and control districts. Presentations for uncomplicated malaria increased in the intervention and control districts to a similar degree. Severe cases increased to a greater degree in the intervention districts immediately after HBM was expanded compared with controls, but the monthly rate of increase was lower in the intervention districts., Conclusions: Services were shifted to CHWs, as demonstrated by the number of individuals treated through the expanded program. The rate of severe malaria increased immediately after implementation within intervention districts relative to controls, potentially because of enhanced case-finding. The rate of increase in severe cases was lower in the intervention districts comparatively, likely due to expedited treatment.

Recurrent chemical meningitis from cyclic leakage of cyst content from a craniopharyngioma is a rare phenomenon. Here, we report a case of leaking cystic craniopharyngioma presenting with recurrent episodes of sterile meningitis, depression, and paranoia. The diagnosis after an initial craniotomy and exploration was hypophysitis. Signs and symptoms were not alleviated by puncture and biopsy of the tumour but they disappeared after complete resection with a final histological diagnosis of craniopharyngioma.

Background: Cerebrovascular accidents or stroke constitute the second leading cause of mortality worldwide. Low- and middle-income countries bear most of the stroke burden worldwide. The main objective of this study is to determine the burden of stroke in Rwanda., Methods: This was a prospective observational study in 2 parts: 6 months baseline data collection and outcome assessment sessions at 1 year., Results: A total of 96 patients were enrolled in our series. Stroke constituted 2100 per 100,000 population. Of all patients, 55.2% were male and most (60%) were 55 years and older. Of all patients and/or caretakers, 22% were not aware of their previous health status and 53.5% of hypertensive patients were not on treatment by the time of the event. Median presentation delay was 72 hours for patients with ischemic stroke and 24 hours for patients with hemorrhagic stroke. Most patients had hemorrhagic stroke (65% vs. 35%), and more patients with hemorrhagic stroke presented with loss of consciousness (80% vs. 51%). Many patients (62% ischemic group and 44% hemorrhagic group) presented with severe stroke scores, and this was associated with worst outcome (P = 0.004). At 1 year follow-up, 24.7% had no or mild disability, 14.3% were significantly disabled, and 61% had died., Conclusions: Our results show that stroke is a significant public health concern in Rwanda. Risk factor awareness and control are still low and case fatality of stroke is significantly high. The significant delay in presentation to care and presentation with severe stroke are major contributors for the high mortality and severe disability rates., (Copyright © 2017 Elsevier Inc.

Objectives: This study was aimed at 1) reporting cases of missed cervical spine injuries treated at a tertiary-level hospital, King Faisal Hospital, Rwanda (KFH-R), and 2) identifying the causes of delaying the diagnosis., Methods: We prospectively collected data from patients with a missed or delayed cervical spine and/or cord injury treated at King Faisal Hospital, Kigali for a 12-month period (January 2012 to December 2012). The total number of cervical spine injury patients treated at our center was retrieved from the hospital admission registry., Results: Forty-two patients with cervical spine or spinal cord injuries were treated at KFH-R in 2012, and 4 of them had a missed or delayed diagnosis. Clinical and radiologic findings of all 4 patients are presented, and the reasons for delaying diagnosis are identified., Conclusion: This study found that the cervical spine injuries were missed in 9.5% of the cervical spine trauma patients and resulted in a longer hospital stay for all 4 patients and severe disability in 1 patient (25%). The reasons for missed diagnoses in this study were 1) lack of cervical spine radiographic evaluation, 2) inadequate cervical spine radiographs to show the level of injury, 3) poor sensitivity of cervical spine plain radiography, 4) poor physical examination, 5) the presence of a distracting injury, and 6) poor sensitivity of radiographs and computed tomography scans for soft tissue injuries., (Copyright © 2016 Elsevier Inc.
