RESUMEN

BACKGROUND: Stigma related to lower-limb lymphoedema poses a major psychosocial burden to affected persons and acts as a barrier to them accessing morbidity management and disability prevention (MMDP) services. Community Conversation (CC), which actively engages community members and disseminates health information amongst them, is believed to break the vicious cycle of stigma by enhancing disease-related health literacy at the community level. METHODS: A quasi-experimental study was conducted in Northern Ethiopia to assess the role of the CC intervention in reducing stigma. In two control districts, a comprehensive and holistic MMDP care package was implemented that included physical health, mental health and psychosocial interventions, whilst in the intervention district the CC intervention was added to the MMDP care package. A total of 289 persons affected by lymphoedema and 1659 community members without lymphoedema were included in the study. RESULTS: Over the course of the intervention, in all sites, community members' knowledge about the causes of lymphoedema increased, and perceived social distance and stigmatizing attitudes towards people with lymphoedema decreased in the community, whilst experienced and internalized stigma decreased amongst affected persons. There were no significant changes for perceived social support. However, the changes were greater in the control sites overall, i.e. those districts in which the holistic care package was implemented without CC. CONCLUSION: The findings suggest that the CC intervention provides no additional stigma reduction when used alongside a holistic MMDP care package. Provision of comprehensive and holistic MMDP services may be adequate and appropriate to tackle stigma related to lower-limb lymphoedema in a resource-constrained setting like Ethiopia.

RESUMEN

BACKGROUND: An estimated 85% of research resources are wasted worldwide, while there is growing demand for context-based evidence-informed health policymaking. In low- and middle-income countries (LMICs), research uptake for health policymaking and practice is even lower, while little is known about the barriers to the translation of health evidence to policy and local implementation. We aimed to compile the current evidence on barriers to uptake of research in health policy and practice in LMICs using scoping review. METHODS: The scoping review followed the Preferred Reporting Items for Systematic Review and Meta-Analyses-extension for Scoping Reviews (PRISMA-ScR) and the Arksey and O'Malley framework. Both published evidence and grey literature on research uptake were systematically searched from major databases (PubMed, Cochrane Library, CINAHL (EBSCO), Global Health (Ovid)) and direct Google Scholar. Literature exploring barriers to uptake of research evidence in health policy and practice in LMICs were included and their key findings were synthesized using thematic areas to address the review question. RESULTS: A total of 4291 publications were retrieved in the initial search, of which 142 were included meeting the eligibility criteria. Overall, research uptake for policymaking and practice in LMICs was very low. The challenges to research uptake were related to lack of understanding of the local contexts, low political priority, poor stakeholder engagement and partnership, resource and capacity constraints, low system response for accountability and lack of communication and dissemination platforms. CONCLUSION: Important barriers to research uptake, mainly limited contextual understanding and low participation of key stakeholders and ownership, have been identified. Understanding the local research and policy context and participatory evidence production and dissemination may promote research uptake for policy and practice. Institutions that bridge the chasm between knowledge formation, evidence synthesis and translation may play critical role in the translation process.

RESUMEN

BACKGROUND: Lower limb lymphoedema (swelling of the lower leg) due to Neglected Tropical Diseases (NTDs) such as podoconiosis, lymphatic filariasis and leprosy is common in Ethiopia, imposing huge burdens on affected individuals and communities. Stigma significantly increases the disease burden and acts as a major barrier to accessing lymphoedema care services. A multi-component stigma reduction intervention was implemented in Northern Ethiopia. Community Conversation (CC) was one of the components implemented, and aimed to reduce stigma and enhance access to and uptake of integrated lymphoedema care services with the active engagement of community members. METHODS: A cross-sectional qualitative process evaluation was conducted to document lessons focusing on CC's relevance, outcomes and implementation challenges. Data were collected from a total of 55 purposively selected participants (26 from the CC intervention site and 29 from the control site) through key informant interviews, in-depth individual interviews and focus group discussions. RESULTS: Community Conversations increased acceptability of health messages about lymphoedema and created peer learning opportunities for unaffected community members. Improvement in the awareness of CC participants about the causes, prevention and treatment of lymphoedema contributed significantly to the reduction of stigmatizing attitudes and discriminatory behaviors, thereby improving access to and utilization of lymphoedema care services provided through primary health care facilities. However, a range of challenges affecting implementation of CC and outcome quality were identified, including perceived complexity of the facilitation guide among facilitators, expectation of incentives among CC participants, inadequate implementation of facilitation principles and procedures, inadequacy of supportive supervision, and low engagement of untrained health workers in CC. CONCLUSIONS: With these challenges addressed, the implementation of CC integrated with other lymphoedema care services shows potential to reduce stigma and promote access to lymphoedema care services.

RESUMEN

Introduction: The COVD-19 pandemic has resulted in unprecedented global health and economic crisis, particularly in countries struggling with poverty. We conducted a national survey to understand the economic and health impacts of COVID-19 in Ethiopia. Methods: A pilot, population-based, cross-sectional survey was conducted among adults randomly selected from the Ethio Telecom list of mobile phone numbers. Participants underwent a comprehensive phone interview about the impact of COVID-19 on their economic well-being and the health-related risks associated with COVID-19. Results: Of 4,180 calls attempted, 1194 were answered, of which a successful interview was made with 614 participants. COVID-19 affected the family income of 343 [55.9%] participants, 56 [9.1%] lost their job, 105 [17.1%] perceived high stress in their household, and 7 [1.14%] reported death in their family in the past month. The odds of having a decreased income due to COVID-19 were 2.4 times higher among self-employed [adjusted odds ratio (AOR) 2.4, 95% CI (1.58-3.77)] and 2.8 times higher among unemployed [AOR 2.8, 95% CI (1.35-5.85)] participants. Two-hundred twenty-one [36%] participants had comorbidity in their household with hypertension, 72 [11.7%], diabetes,50 [8.1%], asthma, 48 [7.8%], and other chronic diseases, 51 [8.4%]. Forty-six [7.5%] participants had COVID-like symptoms in the previous month, where cough, headache, and fatigue were the most common. Conclusion: COVID-19 posed serious economic pressure on households. Self-employed and unemployed were the most affected. Continuous surveillance is needed to actively monitor the impact of COVID-19 in the community and safeguard the economic and health well-being of individuals and households.

RESUMEN

BACKGROUND: Shortage of skilled workforce is a global concern but represents a critical bottleneck to Africa's development. While global academic partnerships have the potential to help tackle this development bottleneck, they are criticised for inadequate attention to equity, impact, and sustainability. We propose a new values-driven partnership model for sustainable and equitable global partnerships that achieve impact. METHOD: The model was based on the authors' experiences of participation in over 30 partnerships and used insights from the Capability Approach. RESULTS: We developed an Academic Partnership Maturity Model, with five levels of maturity, extending from pre-contemplative to mature partnerships. The level of maturity increases depending on the level of freedom, equity, diversity, and agency afforded to the partners. The approach offers a framework for establishing a forward-looking partnership anchored in mutual learning, empowerment, and autonomy. CONCLUSION: This is a pragmatic model limited by the biases of experiential knowledge. Further development of the concept, including metrics and an evaluation tool kit are needed to assist partners and funders.

RESUMEN

BACKGROUND: Neglected Tropical Diseases (NTDs) such as podoconiosis, lymphatic filariasis (LF) and leprosy mainly affect communities in low resource settings. These diseases are associated with physical disability due to lymphoedema as well as poor mental health and psychosocial outcomes. Integration of care across these NTDs at primary health care level, which includes mental health and psychosocial care alongside physical health care, is increasingly recommended. METHODS: A holistic integrated care package was developed and piloted as part of the EnDPoINT project in Gusha district, Awi zone, Ethiopia. The intervention was conducted at the health care organization, health facility and community levels. To assess the impact of the care package in terms of acceptability, scalability, sustainability and barriers to implementation, a qualitative study was conducted in January 2020. This included four focus group discussions (29 participants) and ten key informant interviews with decision makers, health professionals, patients, and community representatives. RESULTS: The integrated lymphoedema care package was found to be efficient compared to vertical programs in saving time and resources. It also resulted in improved awareness of the causes, treatment and prevention of lymphoedema, in marked improvements in the lymphoedema, and in reduced stigma and discrimination. The care package was found to be acceptable to patients, health professionals and decision makers. The barriers to integrated care were unrealistic patient expectations, inadequate dissemination across health workers, and poor transportation access. Health professionals, decision makers and patients believed the integrated lymphoedema care package to be scalable and sustainable. CONCLUSION: The integrated holistic care package was found to be acceptable to patients, health professionals and decision makers. We recommend its scale-up to other endemic districts.

RESUMEN

BACKGROUND: Africa's economic transformation relies on a radical transformation of its higher education institutions. The establishment of regional higher education Centres of Excellence (CoE) across Africa through a World Bank support aims to stimulate the needed transformation in education and research. However, excellence is a vague, and often indiscriminately used concept in academic circles. More importantly, the manner in which aspiring institutions can achieve academic excellence is described inadequately. The main objective of this paper is to describe the core processes of excellence as a prerequisite to establishing academic CoE in Africa. METHODS: The paper relies on our collaborative discussions and real-world insight into the pursuit of academic excellence, a narrative review using Pubmed search for a contextual understanding of CoEs in Africa supplemented by a Google search for definitions of CoEs in academic contexts. RESULTS: We identified three key, synergistic processes of excellence central to institutionalizing academic CoEs: participatory leadership, knowledge management, and inter-disciplinary collaboration. (1) Participatory leadership encourages innovations to originate from the different parts of the organization, and facilitates ownership as well as a culture of excellence. (2) Centers of Excellence are future-oriented in that they are constantly seeking to achieve best practices, informed by the most up-to-date and cutting-edge research and information available. As such, the process by which centres facilitate the flow of knowledge within and outside the organization, or knowledge management, is critical to their success. (3) Such centres also rely on expertise from different disciplines and 'engaged' scholarship. This multidisciplinarity leads to improved research productivity and enhances the production of problem-solving innovations. CONCLUSION: Participatory leadership, knowledge management, and inter-disciplinary collaborations are prerequisites to establishing academic CoEs in Africa. Future studies need to extend our findings to understand the processes key to productivity, competitiveness, institutionalization, and sustainability of academic CoEs in Africa.

RESUMEN

BACKGROUND: We use the example of the Gojjam Lymphoedema Best Practice Trial (GoLBeT), a pragmatic trial in a remote rural setting in northern Ethiopia, to extract lessons relevant to other investigators balancing the demands of practicality and community acceptability with internal and external validity in clinical trials. METHODS: We explain in detail the preparation for the trial, its setting in northern Ethiopia, the identification and selection of patients (inclusion and exclusion criterion, identifying and screening of patients at home, enrollment of patients at the health centres and health posts), and randomisation. RESULTS: We describe the challenges met, together with strategies employed to overcome them. CONCLUSIONS: Examples given in the previous section are contextualised and general principles extracted where possible. We conclude that it is possible to conduct a trial that balances approaches that support internal validity (e.g. careful design of proformas, accurate case identification, control over data quality and high retention rates) with those that favour generalisability (e.g. 'real world' setting and low rates of exclusion). Strategies, such as Rapid Ethical Assessment, that increase researchers' understanding of the study setting and inclusion of hard-to-reach participants are likely to have resource and time implications, but are vital in achieving an appropriate balance. TRIAL REGISTRATION: ISRCTN67805210, registered 24/01/2013.

RESUMEN

BACKGROUND: Currently available diagnostic techniques of Plasmodium falciparum infection are not optimal for non-invasive, population-based screening for malaria. It was hypothesized that a mass spectrometry-based metabolomics approach could identify urinary biomarkers of falciparum malaria. METHODS: The study used a case-control design, with cases consisting of 21 adults in central Ethiopia with a diagnosis of P. falciparum infection confirmed with microscopy, and 25 controls of adults with negative blood smears for malaria matched on age and sex. Urinary samples were collected from these individuals during presentation at the clinic, and a second sample was collected from both cases and controls 4 weeks later, after the cases had received anti-malarial medication. The urine samples were screened for small molecule urinary biomarkers, using mass spectrometry-based metabolomics analyses followed by multivariate analysis using principal component analysis and orthogonal partial least square-discriminant analysis. The chemical identity of statistically significant malaria biomarkers was confirmed using tandem mass spectrometry. RESULTS: The urinary metabolic profiles of cases with P. falciparum infection were distinct from healthy controls. After treatment with anti-malarial medication, the metabolomic profile of cases resembled that of healthy controls. Significantly altered levels of 29 urinary metabolites were found. Elevated levels of urinary pipecolic acid, taurine, N-acetylspermidine, N-acetylputrescine and 1,3-diacetylpropane were identified as potential biomarkers of falciparum malaria. CONCLUSION: The urinary biomarkers of malaria identified have potential for the development of non-invasive and rapid diagnostic test of P. falciparum infection.

RESUMEN

Podoconiosis is a geochemical disease occurring in individuals exposed to red clay soil of volcanic origin. This Neglected Tropical Disease (NTD) is highly prevalent in Ethiopia. According to the nationwide mapping in 2013, the disease is endemic in 345 districts, where an estimated 35 million people live. The government of Ethiopia prioritized podoconiosis as one of eight priority NTDs and included it in the national integrated master plan for NTDs. An integrated lymphoedema management guideline has been developed. Service expansion has continued in the last few years and lymphoedema management services have been expanded to over one hundred endemic districts. The last few years have been critical in generating evidence about the distribution, burden and effective interventions for podoconiosis in Ethiopia. Although the extent of the problem within Ethiopia is considerable, the country is well positioned to now scale-up elimination efforts. Given the extraordinary progress of the past ten years and the current commitment of government, private and third sectors, Ethiopia seems to be on course for the elimination of podoconiosis in our lifetime. We need continued strong partner commitment, evidence-building, and scale-up of activities to accomplish this.

RESUMEN

BACKGROUND: The suitability of using clinical assessment to identify patients with podoconiosis in endemic communities has previously been demonstrated. In this study, we explored the feasibility and accuracy of using Community Health Implementers (CHIs) for the large scale clinical screening of the population for podoconiosis in North-west Cameroon. METHODS: Before a regional podoconiosis mapping, 193 CHIs and 50 health personnel selected from 6 health districts were trained in the clinical diagnosis of the disease. After training, CHIs undertook community screening for podoconiosis patients under health personnel supervision. Identified cases were later re-examined by a research team with experience in the clinical identification of podoconiosis. RESULTS: Cases were identified by CHIs with an overall positive predictive value (PPV) of 48.5% [34.1-70%]. They were more accurate in detecting advanced stages of the disease compared to early stages; OR 2.07, 95% CI = 1.15-3.73, p = 0.015 for all advanced stages). Accuracy of detecting cases showed statistically significant differences among health districts (χ2 = 25.30, p = 0.0001). CONCLUSION: Podoconiosis being a stigmatized disease, the use of CHIs who are familiar to the community appears appropriate for identifying cases through clinical diagnosis. However, to improve their effectiveness and accuracy, more training, supervision and support are required. More emphasis must be given in identifying early clinical stages and in health districts with relatively lower PPVs.

RESUMEN

BACKGROUND: Maximizing comprehension is a major challenge for informed consent processes in low-literacy and resource-limited settings. Application of rapid qualitative assessments to improve the informed consent process is increasingly considered useful. This study assessed the effects of Rapid Ethical Assessment (REA) on comprehension, retention and quality of the informed consent process. METHODS: A cluster randomized trial was conducted among participants of HPV sero-prevalence study in two districts of Northern Ethiopia, in 2013. A total of 300 study participants, 150 in the intervention and 150 in the control group, were included in the study. For the intervention group, the informed consent process was designed with further revisions based on REA findings. Informed consent comprehension levels and quality of the consent process were measured using the Modular Informed Consent Comprehension Assessment (MICCA) and Quality of Informed Consent (QuIC) process assessment tools, respectively. RESULT: Study recruitment rates were 88.7 % and 80.7 % (p = 0.05), while study retention rates were 85.7 % and 70.3 % (p < 0.005) for the intervention and control groups respectively. Overall, the mean informed consent comprehension scores for the intervention and control groups were 73.1 % and 45.2 %, respectively, with a mean difference in comprehension score of 27.9 % (95 % CI 24.0 % - 33.4 %; p < 0.001,). Mean scores for quality of informed consent for the intervention and control groups were 89.1 % and 78.5 %, respectively, with a mean difference of 10.5 % (95 % CI 6.8 -14.2 %; p < 0.001). CONCLUSION: Levels of informed consent comprehension, quality of the consent process, study recruitment and retention rates were significantly improved in the intervention group. We recommend REA as a potential modality to improve informed consent comprehension and quality of informed consent process in low resource settings.

RESUMEN

BACKGROUND: Podoconiosis is a tropical lymphedema resulting from long-term barefoot exposure to red-clay soil derived from volcanic rock. The World Health Organization recently designated it as a neglected tropical disease. Podoconiosis develops in only a subgroup of exposed people, and studies have shown familial clustering with high heritability (63%). METHODS: We conducted a genomewide association study of 194 case patients and 203 controls from southern Ethiopia. Findings were validated by means of family-based association testing in 202 family trios and HLA typing in 94 case patients and 94 controls. RESULTS: We found a genomewide significant association of podoconiosis with the single-nucleotide polymorphism (SNP) rs17612858, located 5.8 kb from the HLA-DQA1 locus (in the allelic model: odds ratio, 2.44; 95% confidence interval [CI], 1.82 to 3.26; P=1.42×10(-9); and in the additive model: odds ratio, 2.19; 95% CI, 1.66 to 2.90; P=3.44×10(-8)), and suggestive associations (P<1.0×10(-5)) with seven other SNPs in or near HLA-DQB1, HLA-DQA1, and HLA-DRB1. We confirmed these associations using family-based association testing. HLA typing showed the alleles HLA-DRB1*0701 (odds ratio, 2.00), DQA1*0201 (odds ratio, 1.91), and DQB1*0202 (odds ratio, 1.79) and the HLA-DRB1*0701-DQB1*0202 haplotype (odds ratio, 1.92) were risk variants for podoconiosis. CONCLUSIONS: Association between variants in HLA class II loci with podoconiosis (a noncommunicable disease) suggests that the condition may be a T-cell-mediated inflammatory disease and is a model for gene-environment interactions that may be relevant to other complex genetic disorders.

RESUMEN

Africa is home to genetically diverse human populations. We compared the genetic structure of the Wolaita ethnic population from Southern Ethiopia (WETH, n=120) with HapMap populations using genome-wide variants. We investigated allele frequencies of 443 clinically and pharmacogenomically relevant genetic variants in WETH compared with HapMap populations. We found that WETH were genetically most similar to the Kenya Maasai and least similar to the Japanese in HapMap. Variant alleles associated with increased risk of adverse reactions to drugs used for treating tuberculosis (rs1799929 and rs1495741 in NAT2), thromboembolism (rs7294, rs9923231 and rs9934438 in VKORC1), and HIV/AIDS and solid tumors (rs2242046 in SLC28A1) had significantly higher frequencies in WETH compared with African ancestry HapMap populations. Our results illustrate that clinically relevant pharmacogenomic loci display allele frequency differences among African populations. We conclude that drug dosage guidelines for important global health diseases should be validated in genetically diverse African populations.

RESUMEN

Podoconiosis is an inflammatory disease caused by prolonged contact with irritant minerals in soil. Major symptoms include swelling of the lower limb (lymphoedema) and acute pain. The disease has major social and economic consequences through stigma and loss of productivity. In the last five years there has been good progress in podoconiosis research and control. Addressing poverty at household level and infrastructure development such as roads, water and urbanization can all help to reduce podoconiosis incidence. Specific control methods include the use of footwear, regular foot hygiene and floor coverings. Secondary and tertiary prevention are based on the management of the lymphoedema-related morbidity and include foot hygiene, foot care, wound care, compression, exercises, elevation of the legs and treatment of acute infections. Certain endemic countries are taking the initiative to include podoconiosis in their national plans for the control of neglected tropical diseases and to scale up interventions against the disease. Advocacy is needed for provision of shoes as a health intervention. We suggest case definitions and elimination targets as a starting point for elimination of the disease.


La podoconiose est une maladie inflammatoire provoquée par un contact prolongé avec des minéraux irritants présents dans le sol. Les principaux symptômes incluent un gonflement des membres inférieurs (lymphœdème) et une douleur aiguë. Cette maladie a d'importantes conséquences sociales et économiques, car elle entraîne stigmatisation et perte de productivité. Ces cinq dernières années ont été marquées par des progrès satisfaisants en matière de recherche sur la podoconiose et de contrôle de cette maladie. Combattre la pauvreté au niveau des foyers et développer des infrastructures routières, d'approvisionnement en eau et urbaines peut contribuer à réduire son incidence. Les méthodes de lutte contre la podoconiose incluent le port de chaussures, une bonne hygiène des pieds et des revêtements de sol. La prévention secondaire et la prévention tertiaire reposent sur la gestion de la morbidité liée aux lymphœdèmes et passent par l'hygiène des pieds, les soins des pieds, les soins des plaies, la compression, des exercices, l'élévation des jambes et le traitement des infections aigües. Certains pays où la podoconiose est endémique ont pris l'initiative de l'inclure dans leur plan national pour la lutte contre les maladies tropicales négligées et de multiplier les interventions contre cette maladie. Des actions de sensibilisation sont nécessaires en vue de la distribution de chaussures comme mesure sanitaire. Nous recommandons de préciser les définitions de cas et les objectifs d'élimination pour servir de point de départ à l'éradication de cette maladie.


La podoconiosis es una enfermedad inflamatoria causada por un contacto prolongado con sustancias minerales irritantes del suelo. Los síntomas principales incluyen la hinchazón de las extremidades inferiores (linfedema) y un dolor agudo. Dicha enfermedad comporta graves consecuencias tanto en el entorno social como económico, ya que provoca estigmas y pérdida de productividad. En los últimos cinco años ha habido progresos satisfactorios en la investigación y el control de la podoconiosis. El tratamiento de la pobreza a nivel doméstico y el desarrollo de infraestructuras como carreteras, riegos y en urbanización pueden ayudar a reducir los casos de podoconiosis. Entre los métodos de control específico se encuentran el uso de calzado, una buena higiene de los pies y recubrimientos para el suelo. La prevención secundaria y terciaria se basa en la gestión de la morbilidad relacionada con el linfedema, esto incluye una buena higiene de los pies y el cuidado de los mismos, la cura de las lesiones, ejercicios de compresión, elevar las piernas y tratar las infecciones agudas. Algunos países endémicos han tomado la iniciativa de incluir la podoconiosis en sus planes nacionales de control sobre enfermedades tropicales desatendidas y aumentar el número de intervenciones para afrontar dicha enfermedad. Se necesita ayuda para suministrar calzado en clave de intervención sanitaria. Nuestra sugerencia para abolir la enfermedad es empezar por definir los casos y eliminar los obstáculos.

RESUMEN

BACKGROUND: Epidemiological and clinical studies in high income countries have suggested that Helicobacter pylori (H. pylori) may cause anaemia, but evidence is lacking from low income countries.We examined associations between H. pylori infection in early childhood and anaemia at the age of 6.5 years in an Ethiopian birth cohort. METHODS: In 2011/12, 856 children (85.1 % of the 1006 original singletons in a population-based birth cohort) were followed up at age six and half. An interviewer-led questionnaire administered to mothers provided information on demographic and lifestyle variables. Haemoglobin level and red cell indices were examined using an automated haematological analyzer (Cell Dyn 1800, Abbott, USA), and stool samples analyzed for H. pylori antigen. The independent effects of H. pylori infection (measured at age 3.5 and 6.5 years) on anaemia, haemoglobin level, and red cell indices (measured at age 6.5 years) were determined using multiple logistic and linear regression. RESULTS: The prevalence of anemia was 34.8 % (257/739), and the mean (SD) haemoglobin concentration was 11.8 (1.1) gm/dl. Current H. pylori infection at age 6.5 years was positively, though not significantly related to prevalence of anaemia (adjusted OR, 95 % CI, 1.15; 0.69, 1.93, p = 0.59). Any H. pylori infection up to age 6.5 years was significantly associated with an increased risk of anaemia at age 6.5 (adjusted OR, 95 % CI, 1.68; 1.22, 2.32, p = 0.01). A significant reduction in haemoglobin concentration and red cell indices was also observed among children who had any H. pylori infection up to age 6.5 (Hb adjusted ß = -0.19, 95 % CI, -0.35 to -0.03, p = 0.01; MCV adjusted ß = -2.22, 95 % CI, -3.43 to -1.01, p = 0.01; MCH adjusted ß = -0.63, 95 % CI, -1.15 to - 0.12, p = 0.01; and MCHC adjusted ß = -0.67, 95 % CI, -1.21 to -0.14, p = 0.01), respectively. CONCLUSION: This study provides further evidence from a low income country that any H. pylori infection up to age 6.5 is associated with higher prevalence of anaemia, and reduction of haemoglobin level and red cell indices at age 6.5.

RESUMEN

Attempts to predict pregnancy and childbirth complications before they occur have not been successful. Provision of safe delivery service for all births is considered to be a critical intervention for ensuring safe motherhood. Hence the aim of the study was to assess factors associated with safe delivery service utilization among women in Sheka Zone South West Ethiopia. A community based comparative cross sectional survey was conducted among 554 women in Sheka Zone from February to March 2008. Data were collected through structured pre-tested questionnaire and entered into Epinfo version 3.3. Analyses were done with SPSS version 13 computer software with which bivariate and multiple logistic regressions were carried out. Mothers who completed at least secondary school were more likely to give birth at health facility than those uneducated (AOR = 3.26, 95 % CI 1.51-7.06). Women with birth order above four were less likely to give birth in a health facility than those with first order births (AOR = 0.21, 95 %CI 0.10-0.43). Women who had encountered problems in their immediate birth and received prenatal care were more likely to give birth at health facilities AOR = 33.78 95 % CI 16.44-69.39) and (AOR = 2.55, 95 % CI 1.05-6.21) respectively. Factors associated with safe delivery service utilization are related to the women's socioeconomic status and obstetric experiences. Consequently promotion of maternal education, prenatal care utilization, information education and communication on obstetric risks and general health service expansion are needed to ensure safe delivery service.

RESUMEN

Health research in Ethiopia is increasing both in volume and type, accompanied with expansion of higher education and research since the past few years. This calls for a proportional competence in the governance of medical research ethics in Ethiopia in the respective research and higher learning institutes. The paper highlights the evolution and progress ofthe ethics review at Addis Ababa University - College of Health Sciences (AAU-CHS) in the given context of health research review system in Ethiopia. Reflections are made on the key lessons to be drawnfrom the formative experiences of the Institutional Review Board (IRB) and their implications to the Ethiopian health research review system. This article is a review paper based on review of published and un published documents on research ethics in Ethiopia and the AAU-CHS (2007-2012). Thematic summaries of review findings are presented in thematic areas - formation of ethics review and key factors in the evolution of ethics review and implications. The IRB at AAU-CHS has been pivotal in providing review and follow-up for important clinical studies in Ethiopia. It has been one of the first IRBs to get WHO/SIDCER recognition from Africa and Ethiopia. Important factors in the successes of the IRB among others included leadership commitment, its placement in institutional structure, and continued capacity building. Financial challenges and sustainability issues need to be addressed for the sustained gains registered so far. Similar factors are considered important for the new and younger IRBs within the emergent Universities and research centers in the country.
