Objective. Diabetic peripheral neuropathy (DPN) is a common microvascular complication of diabetes mellitus (DM) and may progress to diabetic foot, which frequently leads to amputation and/or disability and death. Data is scanty on the burden of diabetic peripheral neuropathy in Tanzania. The aim of this study was to assess the burden of peripheral neuropathy, its severity, and the associated factors. Methods. The study was a cross-sectional hospital-based study and was carried out from October 2017 to March 2018 among adolescent and adult patients attending Kilimanjaro Christian Medical Center (KCMC) diabetes clinic. Results. A total of 327 diabetic patients, females n=215 (65.7%) and males n=121 (34.3%), were included in the study. The mean age was 57.2 yrs. A total of 238 (72%) had type 2 and 89 (27.2%) had type1 DM. The prevalence of peripheral neuropathy was 72.2% of whom 55% were severe, 19% were moderate, and 26% were mild. The severity of neuropathy increased with the increase in age >40 years (p < 0.001) and increase in body mass index (p<0.001) and duration of diabetes; duration >7 years (p <0.006). The main associated factors were age >40 years, OR 2.8 (1.0-7.7), >60 years, OR 6.4 (2.3-18.2), obesity, OR 6.7 (0.9-27.7), and hypertension, OR 4.3 (2.2-8.2). Conclusion. More than half of the patients included in this study were found to have neuropathy, nearly half of whom presented with the severe form. The main risk factors were increasing age, increasing duration of diabetes, obesity, and hypertension. Diabetic peripheral neuropathy is underdiagnosed in northern Tanzania where screening for neuropathy is not routinely done.
As coronavirus disease 2019 (COVID-19) spreads across Africa, little is known about the impact of the pandemic on health-care workers (HCWs) in the region. We designed an anonymous survey distributed via e-mail and phone messaging to 13 countries through the African Hepatitis B Network. We obtained 489 analyzable responses. We used risk ratio analysis to quantify the relationship between binary variables and χ2 testing to quantify the statistical significance of these relationships. Median age of respondents was 30 years (interquartile range, 26–36 years) and 63% were physicians. The top three sources of information used by HCWs for COVID-19 management included the Ministry of Health of each country, the WHO, and social media. Forty-nine percent reported a decrease in income since the start of the pandemic, with the majority experiencing between a 1% and a 25% salary reduction. Sixty-six percent reported some access to personal protective equipment; only 14% reported appropriate access. Moreover, one third of respondents reported no availability of ventilators at their facility. Strikingly, the percentage of HCWs reporting never feeling depressed changed from 61% before the pandemic to 31% during the pandemic, with a corresponding increase in daily depressive symptoms from 2% to 20%. Most respondents (> 97%) correctly answered survey questions about COVID-19 symptoms, virus transmission, and prevention. Our survey revealed African HCWs face a variety of personal and professional context-dependent challenges. Ongoing support of HCWs through and after the COVID-19 pandemic is essential.
Abstract. Healthcare workers are at increased risk of contracting hepatitis B virus (HBV), particularly in settings of high HBV seroprevalence, such as sub-Saharan Africa. We evaluated HBV knowledge among health-care workers in rural Tanzania by distributing an HBV paper survey in two northern Tanzanian hospitals. There were 114 participants (mean age 33 years, 67% female). Of the participants, 91% were unaware of their HBV status and 89% indicated they had never received an HBV vaccine, with lack of vaccine awareness being the most common reason (34%), whereas 70% were aware of HBV complications and 60% understood routes of transmission. There was a significant difference in knowledge of HBV serostatus and vaccination between participants with a medical background and others, P = 0.01 and 0.001, respectively. However, only 33% of consultants (senior medical staff) knew their HBV serostatus. There was no significant difference between knowledge of HBV transmission routes and occupation. Our study reveals low knowledge of HBV serostatus and vaccination status among hospital workers in Tanzania.Infection with the hepatitis B virus (HBV) represents a major cause of morbidity and mortality worldwide, with an estimated 350 million people infected, of which the great majority reside in Asia and sub-Saharan Africa.1,2 Chronic infection with HBV can lead to cirrhosis and/or liver cancer. The therapeutic resources to battle either cirrhosis or liver cancer in the developing world are scarce, and in sub-Saharan Africa, both conditions carry an extremely high risk of mortality within a year of diagnosis.2,3 It is well known that health-care workers are at increased risk for HBV transmission, largely due to transmission via blood contacting mucosa. 4,5 Although the likelihood of chronic disease during contact with HBV in adulthood is low, the probability of being infected through this route is higher than with the human immunodeficiency virus (HIV). 6The risk of HBV transmission in health-care workers is highest in a setting of high seroprevalence of the virus within a population, such as sub-Saharan Africa, where the overall prevalence of hepatitis B surface antigen in blood is > 8%. 2,5 In this environment, adherence to universal precautions is critical to prevent HBV transmission. A recent survey regarding occupational exposure in Tanzania observed that nearly half of health-care workers experienced at least one occupational injury within the 12 months preceding the survey. 7 In that study, workers were mainly concerned about transmission of HIV. Knowledge of HBV transmission risks in African healthcare facilities is important since it is likely to modify healthcare workers' adherence to precautions. 8In this study, we aimed to assess the knowledge of HBV serostatus as well as barriers to HBV vaccination in Tanzanian health-care workers. We provided a paper survey to staff in two hospitals in northern Tanzania (Arusha Lutheran Medical Center and Selian Lutheran Hospital, both within the Arusha region of northern Tanzania...
