Background :Telemedicine is a rapidly expanding technology used in healthcare settings, especially since the emergence of COVID-19. For this intervention to be implemented successfully, important skills are required from health professionals. Hence, this study seeks to determine the preparedness of African medical students for the use of telemedicine in healthcare delivery by assessing their knowledge, attitude, and skill set , Methods: This was a descriptive cross-sectional study. Data were collected online through a 33-item pre-tested, self-administered questionnaire from three selected medical schools in Africa. Data were analysed using descriptive and analytical statistics with a significant level of 0.05. Data analysis was done on SPSS version 20, Results : Only 559 respondents were eligible for the study. 338 (60.5%) were male and the most prevalent age range was 21-23 years (276, 49.4%). 346 (61.9%) had good knowledge while 461 (82.5%) expressed a good attitude toward telemedicine. Only 144 (25.8%) had a good skill set in using telemedicine. 513 (91.6%) respondents agreed and strongly agreed that the use of telemedicine should be included in medical training. There was a statistically significant association between the skill set of respondents and schools (p=0.001) and gender (pConclusions: The respondents have a good attitude but average knowledge and poor skill set of telemedicine usage in healthcare delivery. However, the majority are interested in learning about telemedicine in medical training. This study shows the need to incorporate telemedicine within the curricula of African medical schools.

Background: The effect of 3 commonly recommended combinations of anti-hypertensive agents—amlodipine plus hydrochlorothiazide (calcium channel blocker [CCB]+thiazide), amlodipine plus perindopril (CCB+ACE [angiotensin-converting enzyme]-inhibitor), and perindopril plus hydrochlorothiazide (ACE-inhibitor+thiazide) on blood pressure variability (V) are unknown. Methods: We calculated the blood pressure variability (BPV) in 405 patients (130, 146, and 129 randomized to ACE-inhibitor+thiazide, CCB+thiazide, and CCB+ACE-inhibitor, respectively) who underwent ambulatory blood pressure monitoring after 6 months of treatment in the Comparisons of Three Combinations Therapies in Lowering Blood Pressure in Black Africans trial (CREOLE) of Black African patients. BPV was calculated using the SD of 30-minute interval values for 24-hour ambulatory BPs and for confirmation using the coefficient of variation. Linear mixed model regression was used to calculate mean differences in BPV between treatment arms. Within-clinic BPV was also calculated from the mean SD and coefficient of variation of 3 readings at clinic visits. Results: Baseline distributions of age, sex, and blood pressure parameters were similar across treatment groups. Participants were predominately male (62.2%) with mean age 50.4 years. Those taking CCB+thiazide had significantly reduced ambulatory systolic and diastolic BPV compared with those taking ACE-inhibitor+thiazide. The CCB+thiazide and CCB+ACE-inhibitor groups showed similar BPV. Similar patterns of BPV were apparent among groups using within-clinic blood pressures and when assessed by coefficient of variation. Conclusions: Compared with CCB-containing combinations, ACE-inhibitor plus thiazide was associated with higher levels, generally significant, of ambulatory and within-clinic systolic and diastolic BPV. These results supplement the differential ambulatory blood pressure–lowering effects of these therapies in the CREOLE trial.

INTRODUCTION Infection is one of the most common causes of maternal morbidities and mortality and has been reported to be responsible for about 15% of maternal deaths. Any woman is at risk of infection during childbirth, but women undergoing cesarean section are at higher risk. Improvement in surgical procedures with asepsis and the use of antibiotics have helped reduce postoperative infectious morbidities. However, ascending infection from the lower to the upper genital tract is a common but often neglected source of infection. Cleaning the vagina with chlorhexidine antiseptic solution before cesarean section can be a cheap and affordable source of infection control. This study is aimed at evaluating the efficacy of preoperative vaginal cleansing using 1.0% chlorhexidine in the reduction of post-cesarean section infectious morbidities. MATERIAL AND METHODS This prospective randomized control trial was conducted among 322 pregnant women who underwent an emergency cesarean section at Alex Ekwueme Federal University Teaching Hospital, Abakaliki (AE-FUTHA). The women were randomized into two groups. The interventional group received vaginal cleansing with three standard gauzes soaked in 30 mL 1.0% chlorhexidine gluconate solution preoperatively in addition to surgical skin cleaning with chlorhexidine-alcohol. The women in the control group only had surgical skin cleaning with chlorhexidine-alcohol. All the women received pre- and postoperative antibiotics. The primary outcomes were endometritis and wound infections. RESULTS Infectious morbidity was significantly reduced from 36.8% in the control group to 12.0% in the intervention group (P = .001). Endometritis occurred significantly less frequently in the intervention group than the control group (respectively 6.6% compared with 27.6%: relative risk [RR] 0.29, 95% confidence interval [CI] 0.16-0.53; P

Background: University undergraduates are at an age when experimentation with sex is prevalent. A significant number of young people still indulge in high risk sexual behavior. Hence, profiling safer sex would be important for the future health of this group. More so an improved knowledge among this group could act as a step down during peer interactions with other non-medical undergraduates. Aim: This study was designed to assess the knowledge and practice of safer sex among Medical undergraduate students and to know to what extent their practice impacts on their health as regards contraction of sexually transmitted infections and having an unwanted pregnancy. Subjects and methods: In this cross-sectional study, three hundred and fifty (350) Medical undergraduate students were interviewed using pretested semi-structured self-administered questionnaires to assess their knowledge and practice of safer sex.

Background Coronary artery disease was hitherto a rarity in Africa. Acute coronary syndrome (ACS) accounts for coronary artery disease–related morbidity and mortality. Reports on ACS in Africa are few. Methods and Results We enrolled 1072 indigenous Nigerian people 59.2±12.4 years old (men, 66.8%) with ACS in an observational multicentered national registry (2013–2018). Outcome measures included incidence, intervention times, reperfusion rates, and 1‐year mortality. The incidence of ACS was 59.1 people per 100 000 hospitalized adults per year, and comprised ST‐segment–elevation myocardial infarction (48.7%), non–ST‐segment–elevation myocardial infarction (24.5%), and unstable angina (26.8%). ACS frequency peaked 10 years earlier in men than women. Patients were predominantly from urban settings (87.3%). Median time from onset of symptoms to first medical contact (patients with ST‐segment–elevation myocardial infarction) was 6 hours (interquartile range, 20.1 hours), and only 11.9% presented within a 12‐hour time window. Traditional risk factors of coronary artery disease were observed. The coronary angiography rate was 42.4%. Reperfusion therapies included thrombolysis (17.1%), percutaneous coronary intervention (28.6%), and coronary artery bypass graft (11.2%). Guideline‐based pharmacotherapy was adequate. Major adverse cardiac events were 30.8%, and in‐hospital mortality was 8.1%. Mortality rates at 30 days, 3 months, 6 months, and 1 year were 8.7%, 9.9%, 10.9%, and 13.3%, respectively. Predictors of mortality included resuscitated cardiac arrest (odds ratio [OR], 50.0; 95% CI, 0.010–0.081), nonreperfusion (OR, 34.5; 95% CI, 0.004–0.221), pulmonary edema (OR, 11.1; 95% CI, 0.020–0.363), left ventricular diastolic dysfunction (OR, 4.1; 95% CI, 0.091–0.570), and left ventricular systolic dysfunction (OR, 2.1; 95% CI, 1.302–3.367). Conclusions ACS burden is rising in Nigeria, and patients are relatively young and from an urban setting. The system of care is evolving and is characterized by lack of capacity and low patient eligibility for reperfusion. We recommend preventive strategies and health care infrastructure‐appropriate management guidelines.

There are limited data from Africa on the burden and associations between pre-diabetes (pre-DM), diabetes mellitus (DM) and stroke occurrence in a region experiencing a profound rise in stroke burden.To characterize the associations between stroke and dysglycemic status among West Africans.The Stroke Investigative Research and Educational Network (SIREN) is a multicenter, case-control study involving 15 sites in Ghana and Nigeria. Cases include adults aged ≥18 years with clinical and radiological evidence of an acute stroke. Controls were age-and-gender matched stroke-free adults. Detailed evaluations for vascular factors were performed. Pre-diabetes was defined as HBA1c of 5.7%-6.4% or Fasting blood glucose (FBG) 5.6-7.0 mmol/L and DM as HBA1c6.5% or FBG7.0 mmol/L. We used conditional logistic regression to estimate adjusted odds ratios (aOR) with 95% Confidence Interval.Among 2,935 stroke cases the mean age was 60.0 ± 14.2 years with 55.2% being males. By glycemic status, 931 (31.7%) were euglycemic, 633 (21.6%) had Pre-diabetes and 1371 (46.7%) had DM. Of the age- and sex-matched stroke-free controls 69.2% were euglycemic, 13.3% had pre-DM and 17.5% had DM. Pre-DM [aOR (95% CI): 3.68(2.61-5.21)] and DM [4.29 (3.19-5.74)] were independently associated with stroke. The aOR of Pre-DM for ischemic stroke 3.06 (2.01-4.64)] was lower than 4.82 (3.37-6.89) for DM. However, the aOR of Pre-DM for hemorrhagic stroke 6.81 (95% CI: 3.29 - 14.08)] was higher than 3.36 (1.94-5.86) for DM. Furthermore, the aOR of pre-DM for ischemic stroke subtypes were 9.64 (1.30-71.57) for cardio-embolic stroke, 3.64 (1.80-7.34) for small-vessel occlusive disease and 4.63 (0.80-26.65) for large-vessel disease.Pre-DM is strongly and independently associated with stroke in Africans. Improving glycemic control through screening, healthy lifestyle and pharmacotherapy at a population level may be strategic in reducing the rising burden of stroke in Africa.

BACKGROUND The prevalence of hypertension among black African patients is high, and these patients usually need two or more medications for blood-pressure control. However, the most effective two-drug combination that is currently available for blood-pressure control in these patients has not been established. METHODS In this randomized, single-blind, three-group trial conducted in six countries in sub-Saharan Africa, we randomly assigned 728 black patients with uncontrolled hypertension (≥140/90 mm Hg while the patient was not being treated or was taking only one antihypertensive drug) to receive a daily regimen of 5 mg of amlodipine plus 12.5 mg of hydrochlorothiazide, 5 mg of amlodipine plus 4 mg of perindopril, or 4 mg of perindopril plus 12.5 mg of hydrochlorothiazide for 2 months. Doses were then doubled (10 and 25 mg, 10 and 8 mg, and 8 and 25 mg, respectively) for an additional 4 months. The primary end point was the change in the 24-hour ambulatory systolic blood pressure between baseline and 6 months. RESULTS The mean age of the patients was 51 years, and 63% were women. Among the 621 patients who underwent 24-hour blood-pressure monitoring at baseline and at 6 months, those receiving amlodipine plus hydrochlorothiazide and those receiving amlodipine plus perindopril had a lower 24-hour ambulatory systolic blood pressure than those receiving perindopril plus hydrochlorothiazide (between-group difference in the change from baseline, −3.14 mm Hg; 95% confidence interval [CI], −5.90 to −0.38; P=0.03; and −3.00 mm Hg; 95% CI, −5.8 to −0.20; P=0.04, respectively). The difference between the group receiving amlodipine plus hydrochlorothiazide and the group receiving amlodipine plus perindopril was −0.14 mm Hg (95% CI, −2.90 to 2.61; P=0.92). Similar differential effects on office and ambulatory diastolic blood pressures, along with blood-pressure control and response rates, were apparent among the three groups. CONCLUSIONS These findings suggest that in black patients in sub-Saharan Africa, amlodipine plus either hydrochlorothiazide or perindopril was more effective than perindopril plus hydrochlorothiazide at lowering blood pressure at 6 months.

Data on the burden and outcomes of recurrent strokes in sub-Saharan Africa are limited, impeding efforts at optimal recurrent stroke prevention.To assess the prevalence, risk factor profile, stroke types and mortality from recurrent strokes in Ghana and Nigeria.We analyzed data from 3553 stroke cases involved in the Stroke Investigative Research and Educational Networks (SIREN) study for proportion with recurrent strokes. Conditional logistic regression models were constructed to interrogate for risk factors of recurrent stroke compared with stroke-free controls. Generalized Linear models were used to assess correlates of recurrent strokes relative to index strokes.Among stroke cases, 335 (9.4%) were recurrent strokes, of which 79.9% were ischemic and 20.1% hemorrhagic. Those with recurrent stroke were significantly older than index stroke cases 62.2 ± 12.9 years vs 58.9 ± 14.0 years, p 0.01 respectively. Topmost risk factors associated with recurrent stroke were hypertension adjusted odds ratio 50.7 (95%CI: 6.6-392.7), dyslipidemia 2.8 (1.3-6.2), diabetes mellitus 4.0 (2.1-7.7) and family history of cardiovascular disease (CVD) 2.1 (1.1-4.2). The relative risk (95%CI) of factors associated with recurrent stroke vs index stroke were age 50 years (1.5: 1.1-2.0); Hausa ethnicity (1.5:1.1-2.1), Yoruba ethnicity with Akan as referent; table added salt (0.4:0.2-0.8) and current alcohol intake (0.6:0.4-0.9). In-patient mortality among those with recurrent stroke vs. primary stroke was 20.5% vs. 21.4%.Several modifiable lifestyle related factors may warrant additional emphasis as targets for reducing the burden of recurrent stroke in sub-Saharan Africa.

Introduction Nurses are the largest healthcare workforce and are not immune to intimate partner violence (IPV) and its consequences. Objective This study is aimed at determining the prevalence, types of IPV, and its determinants among female nurses and nursing students in a tertiary teaching hospital in Abakaliki, Ebonyi State, Nigeria. Methods This cross-sectional study was done in a teaching hospital in Abakaliki between 1st March 2018 and 31st May 2018 to evaluate the prevalence of IPV in the past 12 months among 460 female nursing students and 460 nurses in the facility. Data were obtained with a structured questionnaire and a Composite Abuse Scale. The data were analyzed using IBM SPSS Statistics version 20 and represented using frequency table, percentages, and odds ratios. The level of significance is at P-value < 0.05. Results The prevalence of IPV was 48.2% for the nursing student and 58.7% for the nurses. The most common form of IPV among nursing students was Emotional and/or Harassment abuse (27.1%) while it was Severe combined abuse (23.9%) among the nurses. The significant determinants of IPV among nursing students were age [OR = 0.61(95%CI0.41-0.92)] and year of study [OR = 0.67 (95%CI 0.51–0.89)]. Male partner being unemployed was associated with increased odds of a female partner experiencing violence. Nurses’ marital status and being in the low socioeconomic class were associated with increased odds of a nurse witnessing IPV. Conclusion The prevalence of IPV in the studied group is unacceptably high. Efforts are therefore needed to prevent IPV in the study groups. Health care managers in the study area should make policies to support nurses/nursing students who have experienced IPV.

Introduction: Pelvic examination in the evaluation of patients can be a source of dissatisfaction and litigation from patients. A chaperone is beneficial in militating against unforeseen circumstances surrounding this clinical examination. Aim: To access the opinions and preferences of patients in pelvic examinations and factors associated with the use of chaperones in Federal Teaching Hospital Abakaliki, Ebonyi State, Nigeria. Materials and Methods: The present study was a cross-sectional study. Women were recruited between October 2017 to April 2018 among patients attending the Gynaecological Clinic at the Federal Teaching Hospital, Abakaliki, Nigeria. A structured questionnaire was used to collect data such as the socio-demographic characteristics, feelings towards pelvic examinations, and preferences about the gender of the examining doctor as well as the presence of a chaperone. Data analysis was done using International Business Machines Statistical Package for the Social Sciences (IBM SPSS) Statistics version 20.0 (IBM Corp., Armonk, NY, USA). Results: Out of 423 questionnaires distributed, 395 respondents completed the survey giving a response rate of 93.4%. The mean age of the respondents were 29.2±6.2 years. Majority of the respondents would prefer to be seen by a female gynaecologist 342 (86.6%). About 50 (12.7%) respondents would decline pelvic examination. The commonest reason given for refusing gynaecologic examination was uncomfortable environment 25 (50%). More than two-third 264 (76.5%) would prefer to have a chaperone present at any pelvic examination. Avoidance of sexual molestation was the commonest reason given for wanting a chaperone to be present 207 (78.4%). Nulliparous women (OR=2.25 95% CI 1.13-4.50) and those with at least a secondary education (OR=7.91 95% CI 4.54-13.78) were also more likely to request a chaperone. Conclusion: Majority of the women in present study wanted the presence of a chaperone during a pelvic examination. It is therefore recommended that chaperones should routinely be offered during pelvic examination in Abakaliki, Ebonyi, Nigeria.

A cross-sectional study was performed in the Alex Ekwueme Federal University Teaching Hospital, Abakaliki, between 1st March 2018 and 31st August 2018. Data were obtained using a structured questionnaire and a Composite abuse scale in 460 females. Study settingThe study was carried out in the Federal Teaching Hospital, Abakaliki. This is the only specialist teaching hospital in the state, receiving referrals from private and mission hospitals in the state and neighboring states. It is sited in Abakaliki, the state capital. It has a nursing and midwifery school for the training of qualified nurses and midwives. Apart from been a center of teaching and learning, it provides 24/7 medical services via the emergency/general outpatient department and specialized units. Study populationThe study population was female nursing students of Federal Teaching Hospital, Abakaliki meeting the inclusion criteria. They were consenting females who were not pregnant and were in an intimate partner relationship for the past 12 months. Those who refused to consent, were sick, or who were not in an intimate partner relationship for the past 12 months were excluded. A simple random sampling method was used to select respondents. They were interviewed between January 2018 and May 2018 in a dedicated office for the study. They were interviewed using a structured questionnaire and the Composite Abuse Scale (CAS) version 2013 (Hegarty, 2005). The questionnaire was completed based on their responses. The social class of the study population was determined based on the social class classification of Olusanya et al. (Olusanya & Okpere, 1985), which uses the educational level of the woman and the occupation of the husband to determine a woman’s social class. The social class of the study participants who were not married was based on that of their parent. They were graded into social classes 1 to 5: social classes 1 and 2 were classified as upper social class while social classes 3, 4, and 5 were classified as lower social class. IPV was defined as actual or threatened physical, sexual, psychological, emotional, or stalking abuse by an intimate partner, while an intimate partner was defined as a current or former spouse or non-marital partner such as a boyfriend or dating partner (Basile, 2007).Sample sizeThe sample size was calculated using the formula for a cross-sectional study (N= Z2 PQ/D2), where N = required sample size, Z = 1.96 at a confidence level at 95%, P = an estimated population of 44.6% (Esere, 2009), D = margin of error at 5%, and Q = 1-P. The sample size for the study was 460 after the addition of a 20% attrition rate.Ethical considerationsEthical approval for this study was obtained from the Health Research and Ethics Committee of Federal Teaching Hospital, Abakaliki, Ebonyi state. The ethical approval number was REC APPROVAL NUMBER 14/11/2017-19/12/2017.Composite abuse scale (CAS)CAS is an easily administered self-report measure that provides standardized subscale scores on four dimensions of intimate partner abuse. It consists of 30 items presented in a six-point format requiring respondents to answer “never”, “only once”, “several times”, “monthly”, “weekly”, or “daily” in twelve months. It assesses the following: severe combined abuse factor, emotional abuse factor, physical abuse factor, and the harassment factor. The CAS is made up of 4 subscales: severe combined abuse (SCA; 8 items, possible score 0-40); physical abuse (7 items, possible score 0-35); emotional abuse (11 items, possible score 0-55), and harassment (4 items, possible score 0-20). The subscale score was calculated and compared with a predetermined cut-off score for each subscale as shown below to determine whether they has suffered that abuse. A subscale score greater than the set score would determine that the respondent had experienced such abuse. The respondent was judged to have suffered an abuse if the overall total score was 7 and above. Data analysisThe data obtained were analyzed using IBM SPSS Statistics 20 software (IBM Corp., Chicago, IL). Frequency tables, the chi-squared test (X2), and logistic regression analysis were used for categorical variables where applicable. The student’s age (≤20 or > 20 years), marital status (married or single), year of education (≤ 3 or > 3 years), and social class (1 and 2, upper social class; 3, 4 and 5, lower social class) were reclassified for easy analysis. The partner’s characteristics were also reclassified into ≤ 30 years and > 30 years. The test of significance was at a p-value < 0.05.

Objective To determine the knowledge, attitude, and practice of antenatal attendees towards COVID-19 in Alex Ekwueme Federal University Teaching Hospital, Abakaliki, Nigeria. Methods A cross-sectional survey was carried out among 430 consenting pregnant women attending antenatal clinics between March 1 and May 30, 2020, using pretested questionnaires. Results The mean age and mean gestational age of the respondents were 30.04 years (95% confidence interval [CI] 28.9-31.1) and 26.3 weeks (95% CI 23.3-29.3), respectively. More than four-fifths (82%) of the women believed that COVID-19 is real and their main source of information was mass media. The majority had adequate knowledge of COVID-19. More than half of the respondents said COVID-19 is a curable disease and that chloroquine can be used. The majority showed a good attitude and preventive practice of COVID-19 disease; however, one-fourth (24%) thought that infected individuals should be killed to prevent the spread of the virus. Conclusion The study population has good knowledge, attitude, and practice of COVID-19 disease. However, it is worrisome that some respondents thought that infected individuals should be killed. Proper education must be given to the populace to avert these negative attitudes while promoting a positive preventive attitude. The study population has adequate knowledge, good attitude, and preventive practice of COVID-19; however, community education is needed to reduce anxiety among the populace.

Background Heart failure (HF), the dominant form of cardiovascular disease in Africans, is mainly due to hypertension, rheumatic heart disease and cardiomyopathy. Cardiomyopathies pose a great challenge because of poor prognosis and high prevalence in low- and middle-income countries (LMICs). Little is known about the etiology and outcome of cardiomyopathy in Africa. Specifically, the role of myocarditis and the genetic causes of cardiomyopathy are largely unidentified in Africans. Method The Afr i can Cardio m yopat h y and My o cardi t is R e gistry P rogram (the IMHOTEP study) is a pan-African multi-centre, hospital-based cohort study, designed with the primary aim of describing the clinical characteristics, genetic causes, prevalence, management and outcome of cardiomyopathy and myocarditis in children and adults. The secondary aim is to identify barriers to the implementation of evidence-based care and provide a platform for trials and other intervention studies to reduce morbidity and mortality in cardiomyopathy. The registry consists of a prospective cohort of newly diagnosed (i.e., incident) cases and a retrospective (i.e., prevalent) cohort of existing cases from participating centres. Patients with cardiomyopathy and myocarditis will be subjected to a standardized 3-stage diagnostic process. To date, 750 patients have been recruited into the multi-centre pilot phase of the study. Conclusion The IMHOTEP study will provide comprehensive and novel data on clinical features, genetic causes, prevalence and outcome of African children and adults with all forms of cardiomyopathy and myocarditis in Africa. Based on these findings, appropriate strategies for management and prevention of the cardiomyopathies in LMICs are likely to emerge.

ObjectiveTo characterize risk factors for spontaneous intracerebral hemorrhage (sICH) occurrence and severity among West Africans.MethodsThe Stroke Investigative Research and Educational Network (SIREN) study is a multicenter case-control study involving 15 sites in Ghana and Nigeria. Patients were adults ≥18 years old with CT-confirmed sICH with age-, sex-, and ethnicity-matched stroke-free community controls. Standard instruments were used to assess vascular, lifestyle, and psychosocial factors. Factors associated with sICH and its severity were assessed using conditional logistic regression to estimate odds ratios (ORs) and population-attributable risks (PARs) with 95% confidence intervals (CIs) for factors.ResultsOf 2,944 adjudicated stroke cases, 854 were intracerebral hemorrhage (ICH). Mean age of patients with ICH was 54.7 ± 13.9 years, with a male preponderance (63.1%), and 77.3% were nonlobar. Etiologic subtypes of sICH included hypertension (80.9%), structural vascular anomalies (4.0%), cerebral amyloid angiopathy (0.7%), systemic illnesses (0.5%), medication-related (0.4%), and undetermined (13.7%). Eight factors independently associated with sICH occurrence by decreasing order of PAR with their adjusted OR (95% CI) were hypertension, 66.63 (20.78–213.72); dyslipidemia, 2.95 (1.84–4.74); meat consumption, 1.55 (1.01–2.38); family history of CVD, 2.22 (1.41–3.50); nonconsumption of green vegetables, 3.61 (2.07–6.31); diabetes mellitus, 2.11 (1.29–3.46); stress, 1.68 (1.03–2.77); and current tobacco use, 14.27 (2.09–97.47). Factors associated with severe sICH using an NIH Stroke Scale score >15 with adjusted OR (95% CI) were nonconsumption of leafy green vegetables, 2.03 (1.43–2.88); systolic blood pressure for each mm Hg rise, 1.01 (1.00–1.01); presence of midline shift, 1.54 (1.11–2.13); lobar ICH, 1.72 (1.16–2.55); and supratentorial bleeds, 2.17 (1.06–4.46).ConclusionsPopulation-level control of the dominant factors will substantially mitigate the burden of sICH in West Africa.

Summary: Background: Sub-Saharan Africa has the highest incidence, prevalence, and fatality from stroke globally. Yet, only little information about context-specific risk factors for prioritising interventions to reduce the stroke burden in sub-Saharan Africa is available. We aimed to identify and characterise the effect of the top modifiable risk factors for stroke in sub-Saharan Africa. Methods: The Stroke Investigative Research and Educational Network (SIREN) study is a multicentre, case-control study done at 15 sites in Nigeria and Ghana. Cases were adults (aged ≥18 years) with stroke confirmed by CT or MRI. Controls were age-matched and gender-matched stroke-free adults (aged ≥18 years) recruited from the communities in catchment areas of cases. Comprehensive assessment for vascular, lifestyle, and psychosocial factors was done using standard instruments. We used conditional logistic regression to estimate odds ratios (ORs) and population-attributable risks (PARs) with 95% CIs. Findings: Between Aug 28, 2014, and June 15, 2017, we enrolled 2118 case-control pairs (1192 [56%] men) with mean ages of 59·0 years (SD 13·8) for cases and 57·8 years (13·7) for controls. 1430 (68%) had ischaemic stoke, 682 (32%) had haemorrhagic stroke, and six (

Background: Whether left ventricular hypertrophy (LVH) is determined by similar genomic and environmental risk factors with stroke, or is simply an intermediate stroke marker, is unknown.Objectives: We present a research plan and preliminary findings to explore the overlap in the genomic and environmental determinants of LVH and stroke among Africans participating in the SIREN (Stroke Investigative Research and Education Network) study.Methods: SIREN is a transnational, multicenter study involving acute stroke patients and age-, ethnicity-, and sex-matched control subjects recruited from 9 sites in Ghana and Nigeria. Genomic and environmental risk factors and other relevant phenotypes for stroke and LVH are being collected and compared using standard techniques.Results: This preliminary analysis included only 725 stroke patients (mean age 59.1 ± 13.2 years; 54.3% male). Fifty-five percent of the stroke subjects had LVH with greater proportion among women (51.6% vs. 48.4%; p < 0.001). Those with LVH were younger (57.9 ± 12.8 vs. 60.6 ± 13.4; p = 0.006) and had higher mean systolic and diastolic blood pressure (167.1/99.5 mm Hg vs 151.7/90.6 mm Hg; p < 0.001). Uncontrolled blood pressure at presentation was prevalent in subjects with LVH (76.2% vs. 57.7%; p < 0.001). Significant independent predictors of LVH were age90 mm Hg (AOR: 2.10; 95% CI: 1.39 to 3.19; p < 0.001).Conclusions: The prevalence of LVH was high among stroke patients especially the younger ones, suggesting a genetic component to LVH. Hypertension was a major modifiable risk factor for stroke as well as LVH. It is envisaged that the SIREN project will elucidate polygenic overlap (if present) between LVH and stroke among Africans, thereby defining the role of LVH as a putative intermediate cardiovascular phenotype and therapeutic target to inform interventions to reduce stroke risk in populations of African ancestry.HighlightsLeft ventricular hypertrophy (LVH) was found in more than one-half of stroke patients in Africa.LVH was more common in younger patients, suggesting a genetic component.Hypertension was a major modifiable risk factor for stroke as well as LVH.SIREN will elucidate polygenic overlap between LVH and stroke among Africans.

Background Tuberculous pericarditis is associated with high morbidity and mortality even if antituberculosis therapy is administered. We evaluated the effects of adjunctive glucocorticoid therapy and Mycobacterium indicus pranii immunotherapy in patients with tuberculous pericarditis. Methods Using a 2-by-2 factorial design, we randomly assigned 1400 adults with definite or probable tuberculous pericarditis to either prednisolone or placebo for 6 weeks and to either M. indicus pranii or placebo, administered in five injections over the course of 3 months. Two thirds of the participants had concomitant human immunodeficiency virus (HIV) infection. The primary efficacy outcome was a composite of death, cardiac tamponade requiring pericardiocentesis, or constrictive pericarditis. Results There was no significant difference in the primary outcome between patients who received prednisolone and those who received placebo (23.8% and 24.5%, respectively; hazard ratio, 0.95; 95% confidence interval [CI], 0.77 to 1.18; P = 0.66) or between those who received M. indicus pranii immunotherapy and those who received placebo (25.0% and 24.3%, respectively; hazard ratio, 1.03; 95% CI, 0.82 to 1.29; P = 0.81). Prednisolone therapy, as compared with placebo, was associated with significant reductions in the incidence of constrictive pericarditis (4.4% vs. 7.8%; hazard ratio, 0.56; 95% CI, 0.36 to 0.87; P = 0.009) and hospitalization (20.7% vs. 25.2%; hazard ratio, 0.79; 95% CI, 0.63 to 0.99; P = 0.04). Both prednisolone and M. indicus pranii, each as compared with placebo, were associated with a significant increase in the incidence of cancer (1.8% vs. 0.6%; hazard ratio, 3.27; 95% CI, 1.07 to 10.03; P = 0.03, and 1.8% vs. 0.5%; hazard ratio, 3.69; 95% CI, 1.03 to 13.24; P = 0.03, respectively), owing mainly to an increase in HIV-associated cancer. Conclusions In patients with tuberculous pericarditis, neither prednisolone nor M. indicus pranii had a significant effect on the composite of death, cardiac tamponade requiring pericardiocentesis, or constrictive pericarditis.
