Community awareness of stroke in Accra, Ghana.

BACKGROUND: Community awareness of stroke, especially the risk factors and warning signs is important in the control of the disease. In sub-Saharan Africa, little is known about community awareness of stroke though the brunt of stroke is currently borne in this region. The aim of the study was to evaluate stroke awareness in Accra (capital city of Ghana) particularly, the risk factors and warning signs. METHODS: This was a cross-sectional study involving systematic sampling of 63 households in each of the 11 sub metropolitan areas of Accra. A structured questionnaire was used to collect stroke awareness data from respondents randomly sampled in the selected households. Logistic regression analyses were done to identify predictors of the main outcome variables including recognition of stroke risk factors, stroke warning signs and the organ affected by stroke. RESULTS: Only 40% (n = 277) of the 693 respondents correctly identified the brain as the organ affected in stroke. Similarly, less than half of the respondents could recognize any of the established stroke risk factors as well as any of the established stroke warning signs. Over 70% (n > 485) of the respondents either believed that stroke is a preventable disease, or lifestyle alterations can be made to reduce the risk of stroke, or stroke requires emergency treatment. In multivariate analysis, predictors of stroke awareness were: age <50 years (OR = 0.56, CI = 0.35-0.92, p = 0.021), presence of a stroke risk factor (OR = 2.37, CI = 1.52-3.71, p < 0.001) and Christian Religion (OR = 14.86, CI = 1.37-161.01, p = 0.03). CONCLUSION: Though stroke is perceived as a serious and preventable disease in Accra, community awareness of the risk factors and warning signs is sub-optimal. This indicates that community-based education programs to increase public awareness of stroke could contribute to decreasing the risk of stroke and to increasing the speed of hospital presentation after stroke onset.

Dynamic HIV-1 genetic recombination and genotypic drug resistance among treatment-experienced adults in northern Ghana.

PURPOSE: There have been hardly any reports on the human immunodeficiency virus type 1 (HIV-1) drug-resistance profile from northern Ghana since antiretroviral therapy (ART) was introduced over a decade ago. This study investigated prevailing HIV-1 subtypes and examined the occurrence of drug resistance in ART-experienced patients in Tamale, the capital of the Northern Region of Ghana. METHODOLOGY: A cross-sectional study was carried out on HIV-infected adult patients receiving first-line ART. HIV viral load (VL) and CD4+ T-cell counts were measured. The pol gene sequences were analysed for genotypic resistance by an in-house HIV-1 drug-resistance test; the prevailing HIV-1 subtypes were analysed in detail.Results/Key findings. A total of 33 subjects were studied. Participants comprised 11 males (33.3 %) and 22 (66.7 %) females, with a median age of 34.5 years [interquartile range (IQR) 30.0-40.3]. The median duration on ART was 12 months (IQR 8.0-24). Of the 24 subjects successfully genotyped, 10 (41.7 %) viruses possessed at least one mutation conferring resistance to nucleoside or non-nucleoside reverse-transcriptase inhibitors (NRTIs/NNRTIs). Two-class drug resistance to NRTI and NNRTI was mostly detected (25 %, 6/24). The most frequent mutations were lamivudine-resistance M184V and efavirenz/nevirapine-resistance K103N. HIV-1 subtype CRF02_AG was predominant (79.2 %). Other HIV-1 subtypes detected were G (8.3 %), A3 (4.2 %) and importantly two (8.3 %) unique HIV-1 recombinant forms with CRF02_AG/A3 mosaic. CONCLUSION: HIV-1 shows high genetic diversity and on-going viral genetic recombination in the study region. Nearly 42 % of the patients studied harboured a drug-resistant virus. The study underscores the need for continued surveillance of HIV-1 subtype diversity; and of drug-resistance patterns to guide selection of second-line regimens in northern Ghana.

Profile and health-related quality of life of Ghanaian stroke survivors.

BACKGROUND: Stroke is a leading cause of mortality with a major effect on health-related quality of life (HRQoL). There are no previous studies exploring HRQoL among stroke survivors in Ghana, despite the increasing public health significance of the disease in this country. Here we describe the profile of and factors associated with HRQoL among stroke survivors in Ghana. METHODS: This was a cross-sectional study involving 156 stroke survivors and 156 age- and sex-matched, apparently healthy controls. A robust HRQoL questionnaire involving seven domains was used to collect data from the study participants. Clinical epidemiology data were also collected from stroke survivors on parameters such as stroke severity and risk factors. Statistical analyses were performed on the interrelationships among the study variables. RESULTS: The mean ages of the stroke survivors and healthy controls were 58.0 (standard deviation, 11.4) and 57.6 (standard deviation, 12.0) years, respectively. Fifty-three percent (86) of the stroke survivors had mild stroke and 35.3% (55) had moderate stroke, whereas 12.2% (19) had severe stroke. Ischemic infarction was the prevalent stroke subtype (78.1%). Hypertension was the most common risk factor (89%) among the stroke survivors, followed by diabetes (29%). HRQoL scores ranged from 57.7% (cognitive domain) to 80.0% (spirit domain) for stroke survivors, whereas HRQoL scores of the control group ranged from 65.6% (cognitive domain) to 85.2% (soul domain). For each HRQoL domain, significantly higher scores were observed for the control group compared with the stroke survivors, at P<0.05. Determinants of HRQoL of stroke survivors in multivariate analysis included age, stroke severity, poststroke duration, stroke recurrence, frequency of laughter, and negative emotions. CONCLUSION: The most affected HRQoL domains are of the physical, psychoemotional, and cognitive domains. Rehabilitation of stroke patients in this region should include interventions targeted at these domains and modifying the statistical determinants of HRQoL where possible.
