Comparison between interventional versus medical therapy in patients with rheumatic mitral valve stenosis in Tanzania.

BACKGROUND: Rheumatic heart disease remains the most common cardiovascular disease in children and young adults. The outcome of interventional versus medical therapy on the long term is not fully elucidated yet. This study provides contemporary data on the clinical profile, treatment and follow up of patients with rheumatic mitral stenosis (MS) in Tanzania. METHODS: Patients' medical information, investigations and treatment data were recorded in this prospective cohort study. They were followed up for 6-24 months to determine the long-term outcome. Interventional therapy was defined as a combination of surgery and percutaneous balloon mitral valvuloplasty. Kaplan-Meier curves and Cox proportional hazards model were used in analyses. p-Value < 0.05 was considered statistically significant. RESULTS: We enrolled 290 consecutive patients. Interventions were done in half of the patients. Median follow up was 23.5 months. Mortality was higher in the medical than interventional treatment (10.4% vs. 4%, log-rank p = 0.001). Median age was 36 years, females (68.3%) and low income (55.5%). Multivalvular disease was found in 116 (40%) patients, atrial fibrillation (31.4%), stroke/transient ischaemic attack (18.9%) and heart failure class III-IV (44.1%). Median (IQR) duration of disease was 3 (4) years, secondary prophylaxis (27.7%) and oral anticoagulants use (62.3%). In multivariable analysis, the risk of death among patients on medical was 3.07 times higher than those on interventional treatment (crude HR 3.07, 95% CI 1.43-6.56, p = 0.004), 2.44 times higher among patients with arrhythmias versus without arrhythmias (crude HR 2.44, 95% CI 1.19-4.49, p = 0.015) and 2.13 times higher among patients with multivalvular than single valve disease (crude HR 2.13, 95% CI 1.09-4.16, p = 0.026). CONCLUSIONS: Intervention is carrying low mortality compared to medical treatment. Arrhythmias and multivalvular disease are associated with a high mortality. Rheumatic MS is more prevalent in young people, females and individuals with low income. There is a late hospital presentation and a low use of both secondary prophylactic antibiotics and anticoagulants.

Day case laparoscopic cholecystectomy at Kilimanjaro Christian Medical Centre, Tanzania.

INTRODUCTION: The Lancet Commission on Global Surgery has promoted the case for safe, affordable surgical care in low- and middle-income countries (LMICs). In 2017, Kilimanjaro Christian Medical Centre (KCMC) in Tanzania introduced a day case laparoscopic cholecystectomy (DCLC) service, the first of its kind in Sub-Saharan Africa (SSA). We aimed to evaluate this novel service in terms of safety, feasibility and acceptability by patients and staff. METHODS: This study used mixed methods and was split into two stages. In stage 1, we reviewed records of all laparoscopic cholecystectomies (LCs) comparing day cases and admissions. These patients were followed up with a telephone questionnaire to investigate complication rates and receive service feedback. Stage 2 consisted of semi-structured interviews with staff exploring the challenges KCMC faced in implementing DCLC. RESULTS: 147 laparoscopic cholecystectomies were completed: 109 were planned for DCLC, 82 (75.2%) of which were successful, whilst 27 (24.8%) patients were admitted. No variables significantly predicted unplanned admission, the commonest causes for which were pain and nausea. In the DCLC group there was 1 readmission. 62 patients answered the follow up questionnaire, 60 (97%) of which were satisfied with the service. Stage 2 interviews suggested staff to be motivated for DCLC but revealed poor organisation of the day case pathway. CONCLUSION: High rates of DCLC combined with low rates of complications and readmission suggests DCLC is feasible at KCMC. However, staff interviews alluded to administrative problems preventing KCMC from reaching its full DCLC potential. A dedicated day case surgery unit would address most of these problems.

Symptoms and predictors of depression among university students in the Kilimanjaro region of Tanzania: a cross-sectional study.

BACKGROUND: Depression is the second leading cause of death among young people worldwide, and severity and suicidality are useful predictors of an adverse outcome. AIM: This study aimed at examining factors associated with depression among university students in Tanzania. METHODS: A cross-sectional study was conducted between March 2018 and July 2019 of undergraduate students across four universities. They completed a self-reported questionnaire collecting socio-demographic, together with a Patient Health Questionnaire (PHQ-9) to screen for depression. A multivariate logistic regression model was used to determine independent predictors of depression. RESULTS: A total of 1047 students completed the study. Their mean (±SD) age was 24.2 (±7) years. 219 students (21.3%) screened positive for probable depression (survey-1 34% vs survey-2 13%). A total of 228 (21.9%) students reported having thoughts of serious self-harm. Factors independently influencing depression included year of study, substance abuse, unhappy interpersonal relationships and chronic mental or physical illness. The presence of an eating disorder was a predictor of depression and was recorded in 7.4% of all students. CONCLUSION: Significant probable depression is present in one fifth of undergraduate students in this study. These results demonstrate a worrying degree of self- reported features of depression among North Tanzanian university students.
