Abstract

fetched live from OpenAlex

Background. This paper reports the baseline characteristics and outcomes of 266 Namibian patients in the Global Registry of Rheumatic Heart Disease.Objective. To describe clinical findings and outcomes in a cohort of children and adults with rheumatic heart disease in Namibia.Methods. Prospective study of all patients with rheumatic heart disease at Windhoek Central Hospital between January 2010 and November 2012.Results. A total of 266 patients were enrolled; median age was 22 years, 72.6% were <30 years old and 60.5% female. The majority (62.8%) had moderate-severe disease; 48.9% were in congestive cardiac failure. Secondary antibiotic prophylaxis was used by 34.2%. Warfarin was used by 75.3% (n=64/85) with clinical indications. Forty-seven (17.6%) had previous valve interventions, of whom 40 (15.0%) had mechanical valve replacements. Over a 2-year follow-up period 19.1% of patients died. Severe valve involvement at enrolment was independently associated with mortality (24.6% v. 5.1% in those without severe disease; hazard ratio 4.9; 95% confidence interval 1.50 - 15.98). Sixty-five (29.8%) of the 218 without previous intervention had valvular intervention after enrolment.Conclusions. In Namibia rheumatic heart disease affects young people who present with severe disease and have a high case fatality rate. Rates of secondary prevention were low. These findings have informed the National Programme for Prevention and Control of Rheumatic Heart Disease in Namibia.

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
