    BACKGROUND: We conducted the first-of-its kind randomized stroke trial in Africa to test whether a THRIVES (Tailored Hospital-based Risk reduction to Impede Vascular Events after Stroke) intervention improved blood pressure (BP) control among patients with stroke. METHODS AND RESULTS: Intervention comprised a patient global risk factor control report card, personalized phone text-messaging, and educational video. Four hundred patients recruited from 4 distinct medical facilities in Nigeria, aged ≥18 years with stroke-onset within one-year, were randomized to THRIVES intervention and control group. The control group also received text messages, and both groups received modest financial incentives. The primary outcome was mean change in systolic BP (SBP) at 12 months. There were 36.5% females, 72.3% with ischemic stroke; mean age was 57.2±11.7 years; 93.5% had hypertension and mean SBP was 138.33 (23.64) mmHg. At 12 months, there was no significant difference in SBP reduction from baseline in the THRIVES versus control group (2.32 versus 2.01 mmHg, P=0.82). In an exploratory analysis of subjects with baseline BP >140/90 mmHg (n=168), THRIVES showed a significant mean SBP (diastolic BP) decrease of 11.7 (7.0) mmHg while control group showed a significant mean SBP (diastolic BP) decrease of 11.2 (7.9) mmHg at 12 months. CONCLUSIONS: THRIVES intervention did not significantly reduce SBP compared with controls. However, there was similar significant decrease in mean BP in both treatment arms in the subgroup with baseline hypertension. As text-messaging and a modest financial incentive were the common elements between both treatment arms, further research is required to establish whether these measures alone can improve BP control among stroke survivors

    The epidemiology of stroke in Africa: A systematic review of existing methods and new approaches
    (Wiley Periodicals, Inc., 2017) Owolabi M.; Olowoyo P.; Popoola F.; Lackland D.; Jenkins C.; Arulogun O.; Akinyemi R.; Akinyemi O.; Akpa O.; Olaniyan O.; Uvere E.; Kehinde I.; Selassie A.; Gebregziabher M.; Tagge R.; Ovbiagele B.
    Accurate epidemiological surveillance of the burden of stroke is direly needed to facilitate the development and evaluation of effective interventions in Africa. The authors therefore conducted a systematic review of the methodology of stroke epidemiological studies conducted in Africa from 1970 to 2017 using gold standard criteria obtained from landmark epidemiological publications. Of 1330 articles extracted, only 50 articles were eligible for review grouped under incidence, prevalence, case-fatality, health-related quality of life, and disability-adjusted life-years studies. Because of various challenges, no study fulfilled the criteria for an excellent stroke incidence study. The relatively few stroke epidemiology studies in Africa have significant methodological flaws. Innovative approaches leveraging available information and communication technology infrastructure are recommended to facilitate rigorous epidemiological studies for accurate stroke surveillance in Africa.
