A Dynamic Regression Modeling of the Prevalence of Stroke in South-East of Nigeria (Published)
Stroke is increasingly becoming one of the major public health issues in Nigeria. This study aimed to predicting future prevalence of stroke in south-east Nigeria in 2022 and 2023, using previous prevalence. The number of patients recorded with stroke (transient ischemic attack) and risk factors hypertension (HT), diabetes mellitus (DM), dyslipidemia (DY), and alcohol (AL) on monthly basis from January 2017 to December 2021 in Enugu State University Teaching Hospital were extracted. The dynamic regression model was applied to the data, best model is selected using Akaike information criterion corrected (AICC), and the model generated is used to predict the number of patients with stroke in 2022 and 2023. A total of 1216 patient records were included in this study. The proportion of hypertension was 51.49%, diabetes mellitus was 7.65%, alcohol was 6.4%, and dyslipidemia was 24.81%. Regression with ARIMA(0,0,1) was the best model. The prediction showed that by December 2022 the number of patients will increase by 29.63% and by December 2023 it will rise to 36.67%. The findings of this study suggest the prevalence of stroke in south-east Nigeria is high and will still rise in the future. There is still need of further research on stroke and other risk factors towards establishing appropriate policy, preventive and management measures.

The Prognosis of Acute Stroke in a Tertiary Health Centre in South-East Nigeria (Review Completed - Accepted)
Background and purpose: Stroke is a common neurologic disorder and it is the third leading cause of mortality worldwide after ischaemic heart disease and cancer. The purpose of this study was to determine the prognosis of acute stroke in Federal Teaching Hospital Abakaliki (FETHA) South-East Nigeria.
Methods: It was a retrospective, descriptive and hospital based study conducted in a tertiary health centre in Abakaliki south-east Nigeria. The stroke register of the neurology unit was reviewed and relevant data were extracted and analyzed.
Results: Stroke accounted for 12% of medical death with 24hour, 7day and 30day mortality rate of 5%, 10% and 15% respectively. Factors associated with mortality include advanced age, female sex, extremes of blood pressure, loss of consciousness and haemorrhagic stroke.
Conclusions: Stroke accounted for significant proportion of medical deaths and its mortality was highest within the first 24hrs post ictus though lower than most hospital based studies. There should be regular health education with emphasis on primary prevention. Also, stroke patients should be referred early to a stroke unit for adequate management
