Early diagnosis of retinoblastoma, the most common intraocular cancer, can save both a child's life and vision. However, anecdotal evidence suggests that many children across world are diagnosed late. To our knowledge, clinical presentation retinoblastoma has never been assessed on global scale. report stage at in patients during single year, to investigate associations between variables national income level, risk factors for advanced disease diagnosis. A total 278 treatment centers were...
Hypertension, the leading single cause of morbidity and mortality worldwide, is a growing public health problem in sub-Saharan Africa (SSA). Few studies have estimated compared burden hypertension across different SSA populations. We conducted cross-sectional analysis blood pressure data collected through cohort study four countries, to estimate prevalence pre-hypertension, hypertension, identify factors associated with hypertension. Participants were from five population groups defined by...
BackgroundRetinoblastoma is the most common intraocular cancer worldwide. There some evidence to suggest that major differences exist in treatment outcomes for children with retinoblastoma from different regions, but these have not been assessed on a global scale. We aimed report 3-year globally and investigate factors associated survival.MethodsWe did prospective cluster-based analysis of treatment-naive patients who were diagnosed between Jan 1, 2017, Dec 31, then treated followed up 3...
At the time of diagnosis, more than 10 % people with type 2 diabetes mellitus have one or two risk factors for a foot ulceration and lifetime 15 %. Diabetic ulcers can be prevented through well-coordinated care services. The objective this study was to determine knowledge reported practice self-care among diabetic patients aim identifying addressing barriers preventing amputations patients.Patients were randomly selected from all public clinics in Dar es Salaam. A questionnaire containing...
Overweight and obesity are on the rise in developing countries including sub-Saharan Africa. We undertook a four-country survey to show collective burden of these health conditions as they occur currently Africa determine differences between urban rural populations other socio-economic factors. Participants were nurses two hospitals Nigeria (200), school teachers South (489) Tanzania (229), village residents one peri-urban (297) location Uganda (200) who completed standardised questionnaire....
BackgroundThe increase in prevalence of diabetes and pre-diabetes sub-Saharan Africa underlines the importance understanding its magnitude causes different population groups. We analyzed data from Africa/Harvard Partnership for Cohort Research Training (PaCT) studies to determine risk factors associated with diabetes.MethodologyParticipants were randomly selected peri-urban (n=297) rural (n=200) communities Uganda, teachers recruited schools (n=229) urban Tanzania. used a standardized...
This study evaluated 1-h plasma glucose (1HrPG) levels during an oral tolerance test (OGTT) in predicting progression to diabetes and prediabetes among individuals with normal (NGT).After analyzing the electronic records of 32,809 subjects who had undergone OGTT, we identified 1,179 NGT at baseline, defined as fasting (FPG) < 100 mg/dL 2-h (2HrPG) 140 mg/dL, least one follow-up OGTT. Receiver operating characteristic curves were constructed derive optimal 1HrPG values, which associated...
Epstein-Barr virus (EBV)-positive Burkitt lymphoma (BL) affects children in sub-Saharan Africa, but diagnosis via tissue biopsy is challenging. We explored a liquid approach using targeted next-generation sequencing to detect the The panel included targets for characteristic detected three of four This analysis demonstrates potential improve BL settings with limited pathology resources. Validation our larger data set needed.
Background: Studies from the Sub-Saharan African (SSA) countries suggest an underestimate of SARS-CoV-2 infections early in pandemic. To understand and inform infection control strategies to protect key vulnerable populations, this study investigated seroprevalence factors associated with anti-SARS CoV-2 seropositivity among healthcare workers (HCWs) Dar es Salaam, Tanzania. Methods: This cross-sectional was conducted three tertiary national hospitals Employed HCWs aged >=18 years were...
To identify predominant dietary patterns in four African populations and examine their association with obesity.Cross-sectional study.Setting/SubjectsWe used data from the Africa/Harvard School of Public Health Partnership for Cohort Research Training (PaCT) pilot study established to investigate feasibility a multi-country longitudinal non-communicable chronic disease sub-Saharan Africa. We applied principal component analysis intake collected an FFQ developed PaCT ascertain Tanzania, South...
Injury-related morbidity is a neglected health concern in many low-income and middle-income countries. Most injury data Africa have been collected from hospital-based studies, few studies occurred across multiple Using novel cohort, we examined the prevalence incidence of serious injuries associated risk factors five sites sub-Saharan (SSA).A common baseline follow-up survey was administered to participants. The study population included 1316 persons at 904 follow-up. Frequencies were...
Abstract Background The capacity for invasive tissue biopsies followed by histopathology diagnosis in sub-Saharan Africa is severely limited. Consequently, many cancer patients are diagnosed late and outcomes poor. Here, we propose to evaluate circulating tumour (ct) DNA analysis (“liquid biopsy”), a less faster approach diagnose endemic EBV-driven lymphomas (EBVL) East Africa. Methods We will the clinical utility of an already validated ctDNA test prospectively head-to-head comparison...
Dietary changes characterized by a reduction in carbohydrate quality are occurring developing countries and may be associated with higher prevalence of obesity chronic diseases such as type 2 diabetes mellitus. We assessed the preferences acceptability unrefined whole grain staples (i.e., brown rice, maize sorghum ugali) substitutes for commonly consumed refined carbohydrates Tanzania. A questionnaire was used to collect sociodemographic information dietary habits, pre-and post-tasting...
The travel distance from home to a treatment centre, which may impact the stage at diagnosis, has not been investigated for retinoblastoma, most common childhood eye cancer. We aimed investigate burden and its on clinical presentation in large sample of patients with retinoblastoma Africa Europe.A cross-sectional analysis including 518 treatment-naïve residing 40 European countries 1024 43 African countries.Capture rate was 42.2% expected 108.8% Europe. were older (95% CI -12.4 -5.4,...
BackgroundLarge prospective epidemiologic studies are vital in determining disease etiology and forming national health policy.
