RESUMO

The burden of neurological disease disproportionately affects low- and middle-income countries, where the lowest number of neurologists are located. Building local training opportunities in resource-limited settings is a foundational step to enhancing the neurological workforce and improving access to neurological care in these regions. In this article, we describe the development and growth of the first neurology residency program in East Africa, which was established in 2006 at Zewditu Memorial Hospital and the Tikur Anbessa Specialized Hospital, Addis Ababa University, Ethiopia. We highlight the impact of the program on clinical care, research, collaborations between neurologists across Ethiopia, and ways to build educational opportunities and mentorship while faced with limited resources. The main challenges in starting the residency program included lack of faculty with neurological expertise, lack of a precedent for subspecialty training in our setting, as well as limited resources and space. The formation of sustainable international collaborations with clinicians at established institutions in high-income countries and neurological societies has been a major source of support in developing the initial infrastructure, curriculum and educational content, knowledge assessments, and mentored research projects. Local partnerships with related medical specialties, including internal medicine, critical care, neurological surgery, and psychiatry, were also instrumental in creating training opportunities. As the program continues to evolve, many challenges remain, including limited diagnostics, lack of access to advanced treatment modalities, lack of fellowship training opportunities in various neurological subspecialties, and insufficient training and experience in scientific writing. Despite these challenges, the residency program has persevered and its creation resulted in many positive changes: since its inception in 2006, we graduated 80 neurologists and the number of practicing neurologists in Ethiopia has increased from 5 to 78, our institution has evolved into a national referral center for neurology, graduates have published 61 articles in the past 3 years and contributed to international neurology research, and alumni of the program have grown the Association of Ethiopian Neurologists. Future directions include development of fellowship opportunities, creation of international rotations, and implementation of teleneurology to further strengthen neurological care across Ethiopia.

RESUMO

BACKGROUND: In the East African region, herbal plants are essential in the treatment and control of cancer. Given the diverse ecological and cultural makeup of the regional states, it is likely that different ethnic groups will use the same or different plants for the same or different diseases. However, since 2019, this has not been compiled into a single study. PURPOSE: The study aimed to compile and record the medicinal plants utilized in East Africa from April 2019 to June 2023 to treat various cancer types. MATERIALS AND METHODS: The study examined 13 original studies that included ethnobotanical research conducted in East Africa. They were retrieved from several internet databases, including Google Scholar, Scopus, PubMed/Medline, Science Direct, and Research for Life. The study retrieved databases on plant families and species, plant parts used, preparation methods and routes of administration, and the country where the ethnobotanical field surveys were conducted. Graphs were produced using the GraphPad Prism 8.125 program (GraphPad Software, Inc., San Diego, CA). Tables and figures were used to present the data, which had been condensed into percentages and frequencies. RESULTS: A total of 105 different plant species from 45 different plant families were identified, including Asteraceae (14), Euphorbiaceae (12), Musaceae (8), and Apocynaceae (7). Uganda registered the highest proportion (46% of the medicinal plants used). The most commonly mentioned medicinal plant species in cancer management was Prunus africana. Herbs (32%), trees and shrubs (28%), and leaves (45%) constituted the majority of herbal remedies. Most herbal remedies were prepared by boiling (decoction) and taken orally (57%). CONCLUSION: East Africa is home to a wide variety of medicinal plant species that local populations and herbalists, or TMP, frequently use in the treatment of various types of cancer. The most frequently used families are Asteraceae and Euphorbiaceae, with the majority of species being found in Uganda. The most frequently utilized plant species is Prunus africana. Studies on the effectiveness of Prunus africana against other malignancies besides prostate cancer are required.

RESUMO

BACKGROUND: Despite the harmful effects of smoking, there have been few studies to pinpoint the factors of this habit, and little is known about it in the East African region. For this reason, this study sought to determine the frequency and factors of cigarette smoking among men in the region. METHODS: Data from recent demographic and health surveys carried out in ten East African countries between 2015 and 2022 were analyzed in this study. Data from 87,022 men was collected. The key factors affecting the smoking rates in the area were investigated using binary and multiple multinomial logistic regression. To ascertain if variables were statistically significant in the final model for binary regression and multiple regression, P values of ≤ 0.2 and < 0.05 were used respectively. RESULTS: Overall, about 14.69% of people currently smoke cigarettes. Of this about 11.03 (95% CI = 10.82, 11.24) was for daily active tobacco use. As compared to < 26-year-old men, men with an age range of 26-35 years (RRR = 2.17, 95% CI: 2.01,2.34), 36-45 years (RRR = 2.82, 95% CI: 2.60, 3.07), and > 45 years old (RRR = 3.68, 95% CI: 3.38, 4.02), were using cigarettes daily rather than no-smoking cigarettes. Men who had begun their first sexual intercourse at the age of 7-19 years (RRR = 6.27,95% CI, 5.35,7.35), 20-25 years (RRR = 4.01, 95% CI, 3.40,4.72), and greater than 25 years old (RRR = 3.08, 95% CI, 2.55,3.71) have shown a higher relative risk ratio to smoke cigarette daily rather than using not smoke cigarette respectively, married (RRR = 0.86, 95% CI, 0.79,0.93), divorced or widowed (RRR = 2.51, 95% CI, 2.27,2.77), middle wealth index (RRR = 2.11, 95% CI 1.98,2.24), and rich (RRR = 1.44, 95% CI, 1.34,1.54), secondary/higher education (RRR = 0.72, 05% CI, 0.66,0.77), rural men (RRR = 0.69, 95% CI, 0.65,0.73), employed men (RRR = 1.26,95% CI, 1.17,1.36), mass media exposure (RRR = 0.76, 95% CI, 0.73,0.81), men who have one sex partner (RRR = 1.23,95% CI,1.13,1.35), and more than one sex partner (RRR = 1.63, 95% CI, 1.47,1.79) more times as compared to those participants who had no sex partner respectively. CONCLUSIONS: Men in East African nations were substantially more likely to smoke cigarettes if they were older, had less education, had a higher wealth index, were divorced or widowed, had many sexual relationships, had early sexual activity, resided in an urban area, were employed, or had no media exposure. The identified factors should be considered by policymakers and public health professionals to lower smoking initiation and increase smoking cessation among men.

RESUMO

INTRODUCTION: Cervical cancer is the most common malignant tumor among women. It is the main cause of death among women in sub-Saharan African countries. Particularly, the incidence and mortality rates are highest in East Africa. Even though the burden of human papilloma virus-related cervical cancer is high in East Africa, there is no conclusive evidence about the prevalence of human papilloma virus vaccine uptake and its predictors. OBJECTIVE: To assess the pooled prevalence of human papilloma virus vaccine uptake and its determinants in East Africa. METHOD: Eligible articles were searched on PubMed, Embase, Scopus, Cochrane Library, Google Scholar, and Google. Those articles incorporating the outcome of interest, both analytical and descriptive study designs, and published or unpublished articles at any time were included. Keywords and Medical Subjects Heading terms or synonyms of human papilloma virus vaccine and Boolean operators were used to retrieve the articles. To assure the quality of articles, Joana Brigg's Institute critical appraisal checklist for cross-sectional studies was used. Sensitivity analysis was conducted to assess the heterogeneity among the studies, and a random effect model was used to analyze the pooled effect size. RESULT: A total of 29 articles were included, and the pooled prevalence of HPV vaccine uptake in East Africa was 35% (95% CI: 26-45%). Good knowledge (OR = 1.6, 95%CI; 1.43-1.8), positive attitude (OR = 2.54, 95% CI; 2.13-3.03), ever heard about HPV vaccine (OR = 1.41, 95% CI; 1.03-1.94), mother educational status above college (OR = 1.84, 95%CI; 1.03-3.31), middle wealth index (OR = 1.33, 95%CI; 1.04-1.7), ≥ 9 family size (OR = 0.76, 95%CI; 0.68-0.98), availability of promotion (OR = 2.53, 95%CI: 1.51-4.26), availability of adequate vaccine (OR = 4.84, 95%CI; 2.9-8.08), outreach vaccination practice (OR = 1.47, 95%CI; 1.02-2.12) and family support (OR = 4.3, 95% CI; 2.98-6.21) were the significant factors for the uptake of human papilloma virus vaccine. CONCLUSION: As compared to the global strategic plan, the pooled prevalence of HPV vaccine uptake in east Africa was low. The uptake of the HPV vaccine was higher among adolescents than youths. Knowledge about the HPV vaccine, attitude towards the HPV vaccine, ever hearing about the HPV vaccine, residence, mother's educational status, mother's occupational status, wealth index, and family size were the significant determinants of HPV vaccine uptake. Therefore, we recommend focusing on awareness creation and behavioral change to expand the uptake of vaccines in East Africa.

RESUMO

INTRODUCTION: In December 2019, the COVID-19 pandemic highlighted the urgent need for rapid collaboration, research, and interventions. International research collaborations foster more significant responses to rapid global changes by enabling international, multicentre research, decreasing biases, and increasing study validity while reducing overall research time and costs. However, there has been low uptake of collaborative research by African institutions and individuals. AIM: To systematically review facilitating factors and challenges to collaborative surgical research studies conducted in Africa. METHODOLOGY: A meta-research review using PubMed®/MEDLINE and Embase on surgical collaboration in Africa from 1st of January 2011 to 31st of September 2021 in accordance to PRISMA guidelines. Surgical studies by collaborative groups involving African authors and sites were included (55 papers). Data on the study period, geographical regions, and research scope, facilitating factors, and challenges were extracted from the studies retrieved from the search. RESULTS: Most of the collaborations in Africa occurred with European institutions (76%). Of the 54 African countries, 63% (34/54) participated in surgical collaborations. The highest collaboration frequency occurred in South Africa (11%) and Nigeria (8%). However, most publications originated from Eastern Africa (43%). Leveraging synergies between high- and low- to middle-income countries (LMICs), well-defined structures, and secure data platforms facilitated collaboration. However, the underrepresentation of collaborators from LMICs was a significant challenge. CONCLUSION: Available literature provides critical insights into the facilitating factors and challenges of research collaboration with Africa. However, there is a need for a detailed prospective study to explore the themes highlighted further. SYSTEMATIC REVIEW REGISTRATION: PROSPERO 2022 CRD42022352115 .

RESUMO

INTRODUCTION: The biggest health problem in East Africa is the human immunodeficiency virus (HIV). Combating stigma and discrimination related to HIV/AIDS is a key goal of many international organizations in their efforts to ensure universal access to HIV/AIDS prevention, treatment, care, and support programs. However, previous studies in various regions of Africa have shown that the prevalence of discriminatory attitudes related to HIV/AIDS is particularly high. Furthermore, there is a current evidence gap in the region. Therefore, the aim of this study was to determine the prevalence of discriminatory attitude toward HIV/AIDS patients, and its associated factors among women in East African countries. METHODS: The data we utilized were gathered from the most recent Demographic and Health Surveys (DHS), which were carried out in east African nations between 2016 and 2022. We integrated DHS data from ten countries into our investigation. For our analysis, a weighted sample of 139,812 women overall was employed. The analysis used multiple logistic regressions. The adjusted odds ratio and its 95% confidence interval were then shown, and components with binary logistic regression p values of less than or equal to 0.2 and < 0.05 were regarded as significant predictors of discrimination against HIV/AIDS patients. RESULTS: In this study, 32.73% (95% CI 34.48-32.97) of respondents had a discriminatory attitude toward HIV/AIDS patients. In the multiple logistic regression analysis, being in the older age groups, having a better education level, being from a wealthy household, having employment status, having ANC follow-up, institutional delivery, mass media exposure, and having female household heads were associated with higher odds of not having a discriminatory attitude toward HIV/AIDS patients. However, being unmarried and living far from the health facilities were associated with higher odds of discriminatory attitudes toward HIV/AIDS patients. CONCLUSION: This study concluded that women in East Africa still had a very discriminatory attitude toward HIV/AIDS patients. The good news for East Africa is that prevalence has decreased when compared to earlier findings. Improving women's empowerment, maternal health services, and health facilities' accessibility are crucial.

RESUMO

BACKGROUND: Helicobacter pylori is the main cause of chronic gastritis, peptic ulcer, lymphoma, and gastric cancer in humans. The prevalence and factors associated with H. pylori infection are varied across countries. Thus, a comprehensive review has not been done on prevalence and associated factors in East Africa. Therefore, this systematic review and meta-analysis aimed to estimate the pooled prevalence and identify factors associated with H. pylori infection in East Africa. METHODS: Articles written in English language were retrieved from PubMed, Scopus, and Science Direct. Relevant articles were selected and screened using Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) guidelines. Publication bias was assessed qualitatively and qualitatively using funnel plot symmetry and Egger's test, respectively. Heterogeneity was assessed using the I2 measure. Data were analyzed using Stata software, version 14, and the "metan" command. RESULTS: A total of 231 articles were retrieved from nineteen countries in East Africa. Of these, 70 articles were eligible for the review. The pooled prevalence of H. pylori in East Africa was 50.98% (95% CI: 45.05-56.90). The prevalence of H. pylori infection ranged from 7.7 to 94.5% in East African countries. The highest pooled prevalence was from Sudan (61.3%, 95% CI: 52.6-69.9), and the lowest prevalence was reported from Uganda (40.7%, 95% CI: 33-48.3). Persons with no formal education (OR: 2.03; 95% CI: 1.22-2.83), lack of hand washing habit after toilet (OR: 2.24; 95% CI: 1.45-3.02), having a history of dyspepsia (OR: 2.25; 95% CI: 1.31-3.18), living in rural areas (OR = 1.80; 95% CI: 0.38-3.23), and having unclean water source (OR = 1.5; 95% CI:0.45-3.45) were all associated with higher risk for H. pylori infection. CONCLUSION: More than half of the populations of East African countries were positive for H. pylori infection. Rural residence, source of water, and alcohol consumption were significantly associated with H. pylori infection. Therefore, healthcare workers could provide health education on the aforementioned risk factors, and the government and other stakeholders could improve the source of drinking water in East Africa.

RESUMO

Burkitt lymphoma (BL) is an aggressive B-cell lymphoma that significantly contributes to childhood cancer burden in sub-Saharan Africa. Plasmodium falciparum, which causes malaria, is geographically associated with BL, but the evidence remains insufficient for causal inference. Inference could be strengthened by demonstrating that mendelian genes known to protect against malaria-such as the sickle cell trait variant, HBB-rs334(T)-also protect against BL. We investigated this hypothesis among 800 BL cases and 3845 controls in four East African countries using genome-scan data to detect polymorphisms in 22 genes known to affect malaria risk. We fit generalized linear mixed models to estimate odds ratios (OR) and 95% confidence intervals (95% CI), controlling for age, sex, country, and ancestry. The ORs of the loci with BL and P. falciparum infection among controls were correlated (Spearman's ρ = 0.37, p = .039). HBB-rs334(T) was associated with lower P. falciparum infection risk among controls (OR = 0.752, 95% CI 0.628-0.9; p = .00189) and BL risk (OR = 0.687, 95% CI 0.533-0.885; p = .0037). ABO-rs8176703(T) was associated with decreased risk of BL (OR = 0.591, 95% CI 0.379-0.992; p = .00271), but not of P. falciparum infection. Our results increase support for the etiological correlation between P. falciparum and BL risk.

RESUMO

BACKGROUND: Spine surgery is a rapidly evolving specialty with a continuous need to learn new skills. In resource-limited settings such as Africa, the need for training is greater. The use of simulation-based training is important in different stages of skill acquisition, especially for high-stake procedures such as spine surgery. Among the available methods of simulation, the use of synthetic models has gained popularity among trainers. METHOD: Twenty participants of a neurosurgery training course, most of whom (65%) were neurosurgery residents and fellows, were recruited. They had hands-on training sessions using a high-fidelity lumbar degenerative spine simulation model and hands-on theater experience. After this, they completed a survey to compare their experience and assess the effectiveness of the lumbar spine model in stimulating real patient and surgery experiences. RESULTS: The participants were from four African countries, and the majority were neurosurgery residents. There were varying levels of experience among the participants in minimally invasive spine surgery, with the majority either having no experience or having only observed the procedure. All the participants said that the high-fidelity lumbar spine model effectively simulated real minimally invasive spine setup and real bone haptics and was effective in learning new techniques. Most of the participants agreed that the model effectively simulated real dura and nerve roots (95%), real muscle (90%), real bleeding from bones and muscles (95%), and real cerbrospinal fluid in the subarachnoid space. Among them, 95% agreed that the model is effective in lumbar minimally invasive spine training in resource-limited settings. CONCLUSION: With the development of new and better surgical techniques, the use of high-fidelity models provides a good opportunity for learning and training, especially in resource-poor settings where there is a paucity of training facilities and personnel.

RESUMO

Adaptive radiations have been instrumental in generating a considerable amount of life's diversity. Ecological opportunity is thought to be a prerequisite for adaptive radiation1, but little is known about the relative importance of species' ecological versatility versus effects of arrival order in determining which lineage radiates2. Palaeontological records that could help answer this are scarce. In Lake Victoria, a large adaptive radiation of cichlid fishes evolved in an exceptionally short and recent time interval3. We present a rich continuous fossil record extracted from a series of long sediment cores along an onshore-offshore gradient. We reconstruct the temporal sequence of events in the assembly of the fish community from thousands of tooth fossils. We reveal arrival order, relative abundance and habitat occupation of all major fish lineages in the system. We show that all major taxa arrived simultaneously as soon as the modern lake began to form. There is no evidence of the radiating haplochromine cichlid lineage arriving before others, nor of their numerical dominance upon colonization; therefore, there is no support for ecological priority effects. However, although many taxa colonized the lake early and several became abundant, only cichlids persisted in the new deep and open-water habitats once these emerged. Because these habitat gradients are also known to have played a major role in speciation, our findings are consistent with the hypothesis that ecological versatility was key to adaptive radiation, not priority by arrival order nor initial numerical dominance.

RESUMO

BACKGROUND: Breast cancer is among the most common cancers globally with a projected increase in incidence and mortality in low- and middle-income countries. The majority of the patients in East Africa present with advanced disease contributing to poor disease outcomes. Breast cancer screening enables earlier detection of the disease and therefore reduces the poor outcomes associated with the disease. This study aims to identify and synthesize the reported barriers and enablers of breast cancer screening among East African women. METHODS: Medline, Embase, SCOPUS, and Cochrane library were searched for articles published on the subject from start to March 2022 using PRISMA guidelines. Also, forward citation, manual search of references and searching of relevant journals were done. A thematic synthesis was carried out on the "results/findings" sections of the identified qualitative papers followed by a multi-source synthesis with quantitative findings. RESULTS: Of 4560 records identified, 51 were included in the review (5 qualitative and 46 quantitative), representing 33,523 women. Thematic synthesis identified two major themes - "Should I participate in breast cancer screening?" and "Is breast cancer screening worth it?". Knowledge of breast cancer and breast cancer screening among women was identified as the most influencing factor. CONCLUSION: This review provides a rich description of factors influencing uptake of breast cancer screening among East African women. Findings from this review suggest that improving knowledge and awareness among both the public and providers may be the most effective strategy to improve breast cancer screening in Eastern Africa.

RESUMO

BACKGROUND: Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients face several hematological abnormalities. Of these abnormalities, anemia is the most common one. Africa has a high prevalence of HIV/AIDS, especially in the East and South African region, which is heavily affected by the virus. Therefore, this systematic review and meta-analysis aimed to determine the pooled prevalence of anemia among patients with HIV/AIDS in East Africa. METHODS: This systematic review and meta-analysis was conducted based on the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis. PubMed, Google Scholar, Science Direct, Dove Press, Cochrane Online, and African journals online were searched systematically. The quality of the included studies was assessed by 2 independent reviewers using the Joanna Briggs Institute critical appraisal tools. Data were extracted into an Excel sheet and then exported to STATA version 11 for analysis. A random-effect model was fitted to estimate the pooled prevalence and Higgins I2 test statistics were done to test the heterogeneity of studies. Funnel plots analysis and Egger-weighted regression tests were done to detect publication bias. RESULTS: The pooled prevalence of anemia among HIV/AIDS patients in East Africa was 25.35% (95% CI: 20.69-30.03%). A subgroup analysis by highly active antiretroviral therapy (HAART) status showed that the prevalence of anemia among HAART naive HIV/AIDS patients was 39.11% (95% CI: 29.28-48.93%) whereas the prevalence among HAART experienced was 36.72% (95% CI: 31.22-42.22%). A subgroup analysis by the study population showed that the prevalence of anemia among adult HIV/AIDS patients was 34.48% (95% CI: 29.52-39.44%) whereas the pooled prevalence among children was 36.17% (95% CI: 26.68-45.65%). CONCLUSION: This systematic review and meta-analysis revealed that anemia is among the most common hematological abnormalities in HIV/AIDS patients in East Africa. It also underscored the importance of taking diagnostic, preventive, and therapeutic measures for the management of this abnormality.

RESUMO

Interferon lambda 4 (IFN-λ4) is a novel type-III interferon that can be expressed only by carriers of the genetic variant rs368234815-dG within the first exon of the IFNL4 gene. Genetic inability to produce IFN-λ4 (in carriers of the rs368234815-TT/TT genotype) has been associated with improved clearance of hepatitis C virus (HCV) infection. The IFN-λ4-expressing rs368234815-dG allele (IFNL4-dG) is most common (up to 78%) in West sub-Saharan Africa (SSA), compared to 35% of Europeans and 5% of individuals from East Asia. The negative selection of IFNL4-dG outside Africa suggests that its retention in African populations could provide survival benefits, most likely in children. To explore this hypothesis, we conducted a comprehensive association analysis between IFNL4 genotypes and the risk of childhood Burkitt lymphoma (BL), a lethal infection-associated cancer most common in SSA. We used genetic, epidemiologic, and clinical data for 4,038 children from the Epidemiology of Burkitt Lymphoma in East African Children and Minors (EMBLEM) and the Malawi Infections and Childhood Cancer case-control studies. Generalized linear mixed models fit with the logit link controlling for age, sex, country, P. falciparum infection status, population stratification, and relatedness found no significant association between BL risk and 3 coding genetic variants within IFNL4 (rs368234815, rs117648444, and rs142981501) and their combinations. Because BL occurs in children 6-9 years of age who survived early childhood infections, our results suggest that additional studies should explore the associations of IFNL4-dG allele in younger children. This comprehensive study represents an important baseline in defining the health effects of IFN-λ4 in African populations.

RESUMO

INTRODUCTION: Tuberculosis (TB) remains a major cause of morbidity and mortality, especially in sub-Saharan Africa. We qualitatively evaluated the implementation of an Evidence-Based Multiple Focus Integrated Intensified TB Screening package (EXIT-TB) in the East African region, aimed at increasing TB case detection and number of patients receiving care. OBJECTIVE: We present the accounts of participants from Tanzania, Kenya, Uganda, and Ethiopia regarding the implementation of EXIT-TB, and suggestions for scaling up. METHODS: A qualitative descriptive design was used to gather insights from purposefully selected healthcare workers, community health workers, and other stakeholders. A total of 27, 13, 14, and 19 in-depth interviews were conducted in Tanzania, Kenya, Uganda, and Ethiopia respectively. Data were transcribed and translated simultaneously and then thematically analysed. RESULTS: The EXIT-TB project was described to contribute to increased TB case detection, improved detection of Multidrug-resistant TB patients, reduced delays and waiting time for diagnosis, raised the index of TB suspicion, and improved decision-making among HCWs. The attributes of TB case detection were: (i) free X-ray screening services; (ii) integrating TB case-finding activities in other clinics such as Reproductive and Child Health clinics (RCH), and diabetic clinics; (iii), engagement of CHWs, policymakers, and ministry level program managers; (iv) enhanced community awareness and linkage of clients; (v) cooperation between HCWs and CHWs, (vi) improved screening infrastructure, (vii) the adoption of the new simplified screening criteria and (viii) training of implementers. The supply-side challenges encountered ranged from disorganized care, limited space, the COVID-19 pandemic, inadequate human resources, inadequate knowledge and expertise, stock out of supplies, delayed maintenance of equipment, to absence of X-ray and GeneXpert machines in some facilities. The demand side challenges ranged from delayed care seeking, inadequate awareness, negative beliefs, fears towards screening, to financial challenges. Suggestions for scaling up ranged from improving service delivery, access to diagnostic equipment and supplies, and infrastructure, to addressing client fears and stigma. CONCLUSION: The EXIT-TB package appears to have contributed towards increasing TB case detection and reducing delays in TB treatment in the study settings. Addressing the challenges identified is needed to maximize the impact of the EXIT-TB intervention.

RESUMO

Cystic echinococcosis (CE) is endemic in humans and domestic animals in eastern Africa. All the species of the Echinococcus granulosus sensu lato complex have been reported in this region except for E. equinus, possibly due to the small number of studies involving equids. This study reports the frequency of different Echinococcus species in donkeys from eastern Africa. A total of 5961 donkeys were examined during meat inspection in 3 slaughterhouses in Kenya. Identification of Echinococcus spp. was achieved through polymerase chain reaction-restriction fragment-length polymorphism and sequencing of the mitochondrial nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit 1 gene. The prevalence of CE was 5.7% (337/5961). The 263 genotyped cysts belonged to E. equinus (n = 163), E. granulosus sensu stricto (n = 70), E. canadensis (G6/7) (n = 26) and E. ortleppi (n = 4). One donkey harboured a metacestode of Spirometra theileri. All E. equinus cases, except 2, originated from southern Ethiopia, whereas the other species were more evenly distributed across the study area. Most of the cysts belonging to E. equinus were fertile (111/163), while those of the other species were non-fertile. This is the first report of Echinococcus spp. in donkeys from sub-Saharan Africa and the first confirmation of E. equinus in East Africa. The frequent fertility of E. equinus cysts in donkeys affirms their suitability as intermediate hosts of this species, while low frequency and cyst fertility suggest a marginal role of donkeys in the transmission of E. granulosus s. s., E. canadensis (G6/7) and E. ortleppi.

RESUMO

INTRODUCTION: Wiskott-Aldrich syndrome is a rare X-linked primary immunodeficiency that mostly presents with a classic triad of eczema, microthrombocytopenia, recurrent infections, and increased risk of autoimmunity/malignancies. CASE PRESENTATION: We present an 8-month-old African male, born from nonconsanguineous parents and who presented with a history of eczematous skin rash since day 9 of life, with recurrent sinus infections, otitis media, and skin abscesses. An elder male sibling who had similar symptoms passed away during infancy. Investigations were consistent with microthrombocytopenia and significantly raised immunoglobulin E, while immunoglobulin A and immunoglobulin G were moderately elevated with normal immunoglobulin M. Genetic testing revealed the patient to be hemizygous for a pathogenic Wiskott-Aldrich syndrome gene variant (NM_000377.2:c.403C>T). He was managed conservatively with supportive treatment until he died a year later. CONCLUSION: Despite Wiskott-Aldrich syndrome being a rare disease, it should be considered as a differential in any male child who presents with microthrombocytopenia and recurrent infections, especially in low-resource settings where genetic testing is not routinely available.

RESUMO

BACKGROUND: The rate of multidrug-resistant tuberculosis is increasing at an alarming rate throughout the world. It is becoming an emerging public health problem in East Africa. The prevalence of multidrug-resistant tuberculosis among pulmonary tuberculosis positive individuals in the region has not been thoroughly investigated. AIM: The aim of this systematic review and meta-analysis is to estimate the pooled prevalence of multidrug-resistant tuberculosis among newly diagnosed and previously treated pulmonary tuberculosis cases in East African countries. METHODS: English published articles were systematically searched from six electronic databases: PubMed, EMBASE, Scopus, Science direct, Web of Science, and Google scholar. The pooled prevalence of multidrug-resistant tuberculosis and associated risk factors were calculated using Der Simonian and Laird's random Effects model. Funnel plot symmetry visualization confirmed by Egger's regression asymmetry test and Begg rank correlation methods was used to assess publication bias. A total of 16 articles published from 2007 to 2019 were included in this study. STATA 14 software was used for analysis. RESULTS: Out of 1025 articles identified citations, a total of 16 articles were included in final meta-analysis. The pooled prevalence of multidrug-resistant tuberculosis among newly diagnosed tuberculosis cases and previously treated tuberculosis patients was 4% (95%CI = 2-5%) and 21% (95%CI: 14-28%), respectively. Living conditions, lifestyles (smoking, alcohol use, and drug abuse), previous medical history, diabetes history, and human immunodeficiency virus infection were risk factors contributing to the higher prevalence of multidrug-resistant tuberculosis in East Africa. CONCLUSION: The review found a significant prevalence of multidrug-resistant tuberculosis in the region. An early diagnosis of tuberculosis and rapid detection of drug-resistant Mycobacterium tuberculosis is a critical priority to identify patients who are not responding to the standard treatment and to avoid transmission of resistant strains. It is also very important to strengthen tuberculosis control and improve monitoring of chemotherapy.

RESUMO

PURPOSE: Lack of education and awareness about cancer treatment may result in suboptimal care of patients with cancer. Unlike high-income countries, resource-limited countries lack the standardized training and scope of practice in oncology nursing. This quality improvement project was conducted to assess nurses' knowledge gain, retention of knowledge and clinical skill set, and feasibility of a blended learning approach in the care of adult oncology patients across four hospitals in Kenya and Tanzania. METHOD: We used a combination of computer-led eLearning sessions and face-to-face interactions over 12 months for cancer education to oncology nurses. Pre- and posttests with each training session were combined with face-to-face clinical skills training at beginning and completion of the course. A comprehensive postassessment was conducted immediately after the training, and at 6, 9, and 12 months to evaluate knowledge gain and retention. CONCLUSION: Of 21 participants across four sites, there was a statistically significant improvement in knowledge scores for 12 participants (P value < .05). The mean pre- and posttest results found significant differences across 10 sessions individually and cumulatively (P value < .01). Results from a one-way repeated measures analysis of variance (ANOVA) test on comprehensive test results suggested that there was no significant difference in knowledge retention across 9 months (F(2, 30) = 1.648412, P > .05). IMPLICATIONS FOR NURSING PRACTICE: Blended learning is an effective tool in improving knowledge, skills, and self-efficacy for clinicians practicing in resource-limited countries. Developing a structured oncology training program has implications for bridging knowledge gaps among clinicians in resource-limited countries and promoting international knowledge exchange.
