Malaria in adults after the start of Covid-19 pandemic: an analysis of admission trends, demographics, and outcomes in a tertiary hospital in the Gambia.

BACKGROUND: Malaria remains a major public health concern in The Gambia. The study assessed the trend of malaria admissions and outcome of adult patients admitted after the start of the COVID-19 pandemic in a tertiary hospital in The Gambia. METHODS: This was a retrospective hospital-based study and data was collected from the 18th October 2020 to 28th February 2023. Demographic data, clinical features, investigations, treatment, and outcomes were recorded. RESULTS: A total of 499 malaria cases were admitted to the hospital over the 29 months of the study period. Data from 320 (67.2% of the total cases) adult patients admitted into the internal medicine department were analysed. The median age was 22 years, range (15-90) and 189 (59.1%) cases were youth with a youth (15-24 years) to older adult (> 24 years) ratio of 1.4:1. The majority of the patients were male 199 (62.2) with a male to female ratio of 1.6:1. The total number of malaria cases admitted into the internal medicine department increased from 103 cases in 2021 to 182 cases in 2022and admission peaked in November in both years. The total number of admitted malaria cases during the peak of the malaria season also increased from 92 patients between September 2021 and December 2021 to 132 patients from September 2022 to December 2022.There was also an increase in both severe and uncomplicated malaria during the same period. The total mortality was 31 (9.7%) and the rate was similar in 2021 9 (8.7%) and 2022 15 (8.4%). Patients with impaired consciousness were more likely to die when compared to those without impaired consciousness [19 (23.6%) vs 12 (5%), p ≤ 0.001]. Patients with acute kidney injury were also more likely to die when compared with those without acute kidney injury [10 (20.4%) vs 15 (7.7%), p = 0.009]. CONCLUSION: The findings show an emerging and consistent trend of malaria admissions and the outcome in the youth and older adult population after the start of the COVID-19 pandemic in The Gambia. This, therefore, suggests the need for the implementation of targeted malaria prevention interventions in this population to further prevent the spread of the disease to the more vulnerable population.

Metabolic Syndrome in HIV: Prevalence, correlates, concordance of Diagnostic Criteria and relationship to Carotid Intimal Media Thickness in a Sub-Saharan Population.

Background: The prevalence and usefulness of MetS in determining CVD risk in at-risk populations are influenced by its definition. In a cohort of HIV-positive Nigerians, we evaluated MetS based on various defining criteria, their agreement with one another, and their association to a CVD endpoint, Carotid-Intimal-Media-Thickness (CIMT). Methodology: In this cross-sectional study, 145 HIV-positive individuals who were enrolled in HIV clinics at the Faith Alive Foundation and Jos University Teaching Hospital in Jos, Nigeria, were randomly chosen. Biophysical and anthropometric measurements including blood pressure, height, weight, waist circumference, and hip-circumference, as well as clinical records, CIMT, fasting plasma glucose, and lipid profile, were assessed. Result: The median (Interquartile range) age of the participants was 41 (35-88) years, and the majority (71.7%) were females. The prevalence of metabolic syndrome (MetS) by the Adult Treatment Panel-III (ATP), International Diabetes Federation (IDF), and Joint Interim Statement (JIS) criteria were 30.3%, 32.4%, and 35.2% respectively. MetS by all criteria was more prevalent among females and participants ≥ 40 years, p<0.05. Low HDLc (93.6-95.5%), Central obesity (86.3-95.5%), and hypertension (80.9-86.4%) were the most frequent components of MetS. HIV-related parameters were not associated with MetS. The overall agreement among MetS criteria was almost perfect between IDF and JIS criteria (k=0.94); and strong between IDF vs., ATP (k=0.82) and ATP vs. JIS (k=0.89). There was no significant difference in the median CIMT in PLHIV with and without MetS across all defining criteria. Conclusion: The prevalence of MetS in PLHIV is relatively high, particularly among females and older individuals. The correlations between the defining criteria were fairly strong and consistent across subpopulations of PLHIV. MetS based on these criteria, however, do not significantly correlate with rising CIMT.

Association of obesity anthropometric indices with hypertension, diabetes mellitus and hypertriglyceridemia in apparently healthy adult Nigerian population.

BACKGROUND: Hypertension, hyperglycemia and hypertriglyceridemia are chronic conditions associated with cardiometabolic diseases. Certain anthropometric indices are known to predict them. AIM: To investigate the association of anthropometric indices with these chronic diseases and which anthropometric index predicts them best. METHODS: In this study, 221 apparently healthy individuals who never received treatments for cardiovascular disease (CVD), diabetes or other chronic diseases participated. The age of the participants ranged from 20-75 years with mean age of 36.9 ± 11.4 years. The risk factors of these diseases namely systolic blood pressures (SBP) and diastolic blood pressures (DBP), fasting blood glucose (FBG) and triglycerides (TG) were determined for all the participants using standard clinical procedures. The obesity anthropometric indices, waist circumference, waist-to-height ratio, waist-to-hip ratio and body mass index as well as abdominal height (AH) and body surface index were determined. The association between each of them with the risk factors were determined by the Pearson correlation method. RESULTS: From the results, it was found that AH showed superiority over the rest for SBP (r = 0.301, P < 0.01), DBP (r = 0.370, P < 0.01), FBG (r = 0.297, P < 0.01) and TG (r = 0.380, P < 0.01). Using the receiver operating characteristic curves, cut-off values of AH for SBP, DBP, FBG and TG were determined to be 24.75 cm, 24.75 cm, 25.25 cm and 24.75 cm respectively. CONCLUSION: The indices of anthropometry used in this study correlated significantly with the studied CVD risk factors, with AH emerging as the most predictive.

Assessment of primary health care workers' knowledge and skill for COPD and asthma screening and diagnosis in Jos LGA of Plateau State.

Introduction: chronic obstructive pulmonary disease and asthma are the commonest of the group of Chronic Respiratory Diseases. Primary Health Care workers play a role in the prevention of these diseases. The aim of this study was to determine the knowledge and diagnostic skills of PHC workers on COPD and asthma in a local government area of Plateau State, Nigeria. Methods: it was a cross-sectional study conducted among 146 primary healthcare workers selected through a multistage sampling technique. Data was collected through a self -administered questionnaire. Data processing and analysis were done with Epi-Info epidemiological software. The categories of knowledge that were of interest were scored and graded. A confidence level of 95% was used and a p-value of <0.05 was considered significant for this study. Results: the mean age of respondents was 41.4 ± 10.1 years, junior community health extension workers made up the largest group and the mean years of service was 14.9 ± 8.9 years. The overall knowledge of COPD and asthma was fair in 68.5 % of health workers though the mean knowledge scores of asthma were statistically significantly higher than that of COPD (p = 0.000). Knowledge was found to be statistically significantly associated with age, sex and cadre. None of the respondents was able to operate a peak flow meter. Conclusion: the study concluded that though there was fair level of knowledge among the respondents on COPD and asthma, they lacked the necessary skills to screen for and diagnose these diseases.

Arterial hypertension in women: Menopause as a risk window.

OBJECTIVES: Cardiovascular diseases (CVD) exert a heavy toll on health of women, mainly due to hypertension said to cluster around the period of transition to menopause. This makes this period a good window to target for prevention and control. We therefore sought to determine if this period really heralds arterial hypertension and CVD in women in our environment. STUDY DESIGN: We secondarily analysed our population data on CVD risk factors in free living rural residents. MAIN OUTCOME VARIABLES: The data considered were blood pressure, anthropometric and biochemical variables in women stratified based on menstruation status. RESULTS: There were 488 females, with 218 still menstruating. They were younger (p = .000), had lower systolic and diastolic blood pressures (p = .000), lower anthropometric indices attaining significance only with waist circumference (p = .001) and lower total cholesterol (p = .001). Controlling for age, statistically significant differences remained for systolic and diastolic blood pressures, body mass index, waist and hip circumferences, and total cholesterol. CONCLUSION: The menopause transition comes with a worse CVD profile. Blood pressure rises and so are the anthropometric variables and some biochemical parameters that fuel CVD. This could be ascribed to age which is higher with those post-menopausal. Controlling for age in this cohort still showed that transiting from pre- to post-menopause still came with CVD burden. Clinicians should take the opportunity presented by menopause transition to screen for CVD risk factors and initiate either preventive or control measures to mitigate morbi-mortality consequences.

Disparities in clinical features and outcomes of peripartum cardiomyopathy in high versus low prevalent regions in Nigeria.

AIMS: The prospective, multicentre Peripartum Cardiomyopathy in Nigeria (PEACE) registry originally demonstrated a high prevalence of peripartum cardiomyopathy (PPCM) among patients originating from Kano, North-West Nigeria. In a post hoc analysis, we sought to determine if this phenomenon was characterized by a differential case profile and outcome among PPCM cases originating elsewhere. METHODS AND RESULTS: Overall, 199 (81.6%) of a total 244 PPCM patients were recruited from three sites in Kano, compared with 45 patients (18.4%) from 11 widely dispersed centres across Nigeria. Presence and extent of ventricular myocardial remodelling during follow-up, relative to baseline status, were assessed by echocardiography. During median 17 months follow-up, Kano patients demonstrated significantly better myocardial reverse remodelling than patients from other sites. Overall, 50.6% of patients from Kano versus 28.6% from other regions were asymptomatic (P = 0.029) at study completion, with an accompanying difference in all-cause mortality (17.6% vs. 22.2% respectively, P = 0.523) not reaching statistical significance. Alternatively, 135/191 (84.9%) of Kano patients had selenium deficiency (<70 µg/L), and 46/135 (34.1%) of them received oral selenium supplementation. Critically, those that received selenium supplementation demonstrated better survival (6.5% vs. 21.2%; P = 0.025), but the supplement did not have significant impact on myocardial remodelling. CONCLUSIONS: This study has shown important non-racial regional disparities in the clinical features and outcomes of PPCM patients in Nigeria, that might partly be explained by selenium supplementation.

Association of Novel Locus With Rheumatic Heart Disease in Black African Individuals: Findings From the RHDGen Study.

Importance: Rheumatic heart disease (RHD), a sequela of rheumatic fever characterized by permanent heart valve damage, is the leading cause of cardiac surgery in Africa. However, its pathophysiologic characteristics and genetics are poorly understood. Understanding genetic susceptibility may aid in prevention, control, and interventions to eliminate RHD. Objective: To identify common genetic loci associated with RHD susceptibility in Black African individuals. Design, Setting, and Participants: This multicenter case-control genome-wide association study (GWAS), the Genetics of Rheumatic Heart Disease, examined more than 7 million genotyped and imputed single-nucleotide variations. The 4809 GWAS participants and 116 independent trio families were enrolled from 8 African countries between December 31, 2012, and March 31, 2018. All GWAS participants and trio probands were screened by use of echocardiography. Data analyses took place from May 15, 2017, until March 14, 2021. Main Outcomes and Measures: Genetic associations with RHD. Results: This study included 4809 African participants (2548 RHD cases and 2261 controls; 3301 women [69%]; mean [SD] age, 36.5 [16.3] years). The GWAS identified a single RHD risk locus, 11q24.1 (rs1219406 [odds ratio, 1.65; 95% CI, 1.48-1.82; P = 4.36 × 10-8]), which reached genome-wide significance in Black African individuals. Our meta-analysis of Black (n = 3179) and admixed (n = 1055) African individuals revealed several suggestive loci. The study also replicated a previously reported association in Pacific Islander individuals (rs11846409) at the immunoglobulin heavy chain locus, in the meta-analysis of Black and admixed African individuals (odds ratio, 1.16; 95% CI, 1.06-1.27; P = 1.19 × 10-3). The HLA (rs9272622) associations reported in Aboriginal Australian individuals could not be replicated. In support of the known polygenic architecture for RHD, overtransmission of a polygenic risk score from unaffected parents to affected probands was observed (polygenic transmission disequilibrium testing mean [SE], 0.27 [0.16] SDs; P = .04996), and the chip-based heritability was estimated to be high at 0.49 (SE = 0.12; P = 3.28 × 10-5) in Black African individuals. Conclusions and Relevance: This study revealed a novel candidate susceptibility locus exclusive to Black African individuals and an important heritable component to RHD susceptibility in African individuals.

Cardiovascular Anthropometry: What Is Best Suited for Large-Scale Population Screening in Sub-Saharan Africa?

Background : Body mass index (BMI) measures overweight/obesity. It, however, especially in sub-Saharan Africa (SSA), misclassifies cardiometabolic risk. Central obesity measures are superior. We therefore sought to compare BMI, waist-to-hip ratio (WHR) and abdominal height (AH) in predicting cardiovascular disease risk in sub-Saharan Africa. Methods : Subjects had blood pressures, BMI, and WHR determined. Blood pressure was taken, weight and height measured to generate BMI, and AH measured with a new locally fabricated abdominometer. The ability of the anthropometric indices in identifying abnormal individuals needing intervention was assessed with sensitivity, specificity, and area under the receiver operator characteristic curve. Results : Adults totaling 1,508 (728 M/780 F) adults were studied. For BMI, 985 (65.3%) were normal, while 375 (24.9%), consisting of 233 males and 142 females, had normal WHR. Blood pressure was normal in 525 (34.8%) and 317 (21.0%) for systolic and diastolic blood pressures, respectively. Using BMI as gold standard, sensitivity, specificity, positive, and negative predictive values for WHR in males were 80.7, 37.5, 62.5, and 19.3%, respectively. For females and in the same order, they were 62.0, 34.3, 65.7, and 38.0%. For AH, it was equal in both genders at 82.6, 39.2, 60.8, and 17.4%. By receiver operating curves comparing AH, WHR, and BMI against blood pressure detection, the area under the curve was 0.745, 0.604, and 0.554 for AH, BMI, and WHR, respectively. Conclusion : Abdominometer-derived AH has a better sensitivity and greater area under the receiver operator curve compared with BMI and WHR in this sub-Sahara African population; implying superiority as a cardiovascular anthropometric index.

Heart Failure with Recovered Ejection Fraction: Report of a Case in Jos, Nigeria.

Some patients in heart failure (HF) are able to withstand treatment, recover ejection fraction (EF) enough to require little or no further treatment. They belong to the distinct entity now called HF with recovered EF where patients start as HF with reduced EF and with treatment end up as HF with mid-range EF or even HF with preserved EF. This case report is on one such patient who presented in HF with features of dilated cardiomyopathy. With treatment, he promptly came out of HF, and myocardium remodeled toward recovery of function, which also reflected on electrocardiographic voltages. He remained out of failure despite deescalation of anti-failure regimen. Characterizing this group well will permit a paradigm shift in the management of HF; with the understanding that the myocardium can recover function or go into remission depending on underlying pathology.

Ultrasound assessed peri-renal fat: an index of sub-clinical atherosclerosis.

OBJECTIVE: Overweight/obesity has predicted cardiovascular disease (CVD) risk for long with its standard measure of body mass index (BMI), which later was found to mis-classify risk oftentimes. This is because it does not differentiate between fat and whole body mass. The finding that fat especially visceral fat was more culpable shifted attention to ectopic fat as a more precise measure of CVD risk. Peri-renal fat (PRF) is one such ectopic foci, which is hardly used despite the relative ease of assessment. We assessed PRF to correlate it with carotid intima media thickness (CIMT) to see if there was any significance in order to obviate need for heavy equipment in CVD risk assessment. METHODS: This is secondary analysis of data generated in the course of studying sub-clinical atherosclerosis in apparently normal individuals. Subjects underwent routine anthropometry to determine BMI. They then underwent abdominal ultrasound studies wherein PRF was measured as the size of the echogenic strip between the posterior part of the liver and the right kidney. The CIMT was measured using the same equipment but a different transducer, as the distance between the intima and medial layers of the right common carotid artery 1 cm proximal to the carotid bulb. RESULTS: The 221 subjects (82 M, 139 F) had mean ages of 37.01±10.97 and 36.86±11.62 years respectively. PRF correlated significantly with CIMT, age and all anthropometric measures. A PRF level of 0.26 cm turned out to be a significant value that determined presence of sub-clinical atherosclerosis deriving from the receiver operating characteristic curve analysis. CONCLUSION: PRF has shown to be correlated significantly with indices that predict atherosclerosis. Being an ectopic fat focus, its local and systemic effects on the kidney increase systemic vascular resistance and CVD. Since it can easily be measured on abdominal ultrasound, a test readily available and requiring lower level skills it should be used to advantage. Levels above 0.26 cm should prompt initiation of curative or preventive action to control CVD in the population.

Subclinical atherosclerosis and associated risk factors among HIV-infected adults in Jos, North Central Nigeria: a cross-sectional study.

INTRODUCTION: human immunodeficiency virus (HIV) is evolving into a leading cause of cardiovascular diseases (CVD) in sub-Saharan Africa (SSA) where the burden of HIV remains high. Atherosclerosis underlie progression to CVD. We therefore examined the prevalence of subclinical atherosclerosis and its association with traditional and non-traditional risk factors for CVD in Nigerian HIV-infected adults. METHODS: this was a cross-sectional study involving randomly selected stable HIV-infected patients with undetectable viral load attending HIV clinics at the Jos University Teaching Hospital and Faith Alive Foundation in Jos, Nigeria. Demographic data, biophysical measurements, cardiovascular risk factors and information regarding HIV-related factors, fasting serum lipid profile, fasting plasma glucose, high-sensitivity C-reactive protein and Carotid-Intima-Media-Thickness (CIMT) were assessed. Subclinical atherosclerosis was defined using a cut-off value of mean CIMT ≥ 0.78 mm. Data were analyzed with the Statistical Package for Social Sciences® (SPSS) software version 23.0 (IBM Corp., Chicago, Illinois, USA). Bivariate analysis and multivariate logistic regression were used to examine the association between risk factors of CVD and subclinical atherosclerosis. The statistical significance level was set at p ≤ 0.05. RESULTS: a total of 148 HIV adults (70.9% being females) on Anti-Retroviral Therapy (ART) were included in this study. The prevalence of subclinical atherosclerosis was 7.4%. Among subjects with subclinical atherosclerosis (SCA), 63.6% were males and 81.8% were hypertensive. Elevated blood glucose, lipids and high-sensitivity C-reactive protein, body mass index (BMI), HIV-related parameters (duration of HIV infection, antiretroviral regimen, CD4+ cell count), current smoking status, alcohol use, were not significantly associated with subclinical atherosclerosis (p>0.05). Male gender [OR(95%CI=4.91(1.36-17.77)], age [OR(95%CI)=1.14(1.06-1.23)], hypertension [OR(95%CI=14.4(3.03-71.86)] and metabolic syndrome [OR(95%CI=8.34(1.73-40.18)] were significantly associated with SCA at bivariate analysis. After adjusting for age, sex and antiretroviral regimen, only increasing age [Adjusted Odds Ratio (AOR) (95% confidence interval (CI)] = 1.12(1.01-1.25)] and hypertension [AOR (95%CI)=10.67 (1.31-87.18)], remained as independent predictors of subclinical atherosclerosis (SCA). CONCLUSION: the prevalence of subclinical atherosclerosis among HIV-infected adults is high in Nigeria. It is significantly associated with increasing age and hypertension. Traditional CVD risk factors such as dyslipidaemia, diabetes mellitus and obesity were not associated with subclinical atherosclerosis in this population.

Multidrug intolerance in the treatment of hypertension: result from an audit of a specialized hypertension service.

BACKGROUND: Hypertension as a cardiovascular disease risk factor continues to take a heavy toll on the population despite efforts with containment. Poor control, even among those on treatment, is part of the challenge and results from patient, physician and health system factors. When the problem resides at patient level, adherence is largely responsible. An entity defined as multidrug intolerance (MDI) is hardly considered. A situation when a patient is willing to adhere but is compelled otherwise could frustrate both patient and physician. Encountering a few such cases prompted the author to audit his specialized hypertension service in order to evaluate the burden of MDI and its associations. METHODS: Between 7 May and 30 July 2016 (to cover a 12-week cycle which ensured all attendees were captured), all patients attending follow up for blood pressure control had their records evaluated for intolerance to three or more different classes of anti-hypertensives, which defines MDI. Their ages, sex, control state and co-morbidities were extracted from the records. RESULTS: A total of 489 patients with hypertension were seen over the period; 271 (55.4%) of whom were women and 248 (50.7%) were uncontrolled. Overall 15 (3.1%) satisfied the definition of MDI; 10 women and 5 men. All the men with MDI were uncontrolled while 7 out of the 10 women were uncontrolled; with two having premenstrual syndrome as co-morbidity. A total of four patients (three men, one woman) had history suggesting allergy and two (one man, one woman) were on treatment for anxio-depressive illness. CONCLUSION: MDI does occur in sub-Sahara African patients with hypertension and should be considered before describing hypertension as resistant or considering alternative treatments including device therapy. Staggering doses or trying different formulations could be of benefit.

Economic benefit of back titration in the treatment of hypertension in Jos, Nigeria.

PURPOSE: Treatment of hypertension is expensive and cost is one of the reasons for inadequate blood pressure control. Where there are no social cost cushions, the burden is borne by patients. With pervasive poverty and inadequate control, complications are unchecked. Back titration in appropriate circumstances should, therefore, translate to economic benefit. This is an attempt to compute, in economic terms, the benefit of back titration. PATIENTS AND METHODS: Thirty-nine patients who entered an antihypertensive back titration program for 12 months and who had been earlier reported on, form the subject of this study. A survey of the cost of antihypertensives in pharmacy outlets in Jos, Nigeria was undertaken. Regimens of antihypertensives that patients were on at the onset and end of the 12 months of back titration were costed in Nigerian currency and compared. RESULTS: Back titration translated to economic benefit in all patients with a cost reduction varying from 2.3% to 100%. This reflected in reduction in mean daily cost of treatment of N107.09-N54.61. CONCLUSION: The benefit of antihypertensive back titration apart from psychological relief of lower pill burden and side effect profile is in pharmacoeconomics. This permits greater adherence and prevents morbi-mortality consequences of hypertension. In this study, back titration over 12 months translated to average cost reduction of >50%, making treatment more affordable. In appropriate circumstances, back titration of antihypertensives results in economic relief for patients. This should improve adherence, reduce morbi-mortality and is recommended for wider application.

Obstetric predictors of hypertension: A cross-sectional study of women attending the postnatal clinic of Jos University Teaching Hospital.

BACKGROUND: Hypertensive disease in pregnancy (HDP) accounts for high mother and child morbi-mortality and predict future cardiometabolic diseases. This study aimed to identify obstetric predictors of HDP needing preventive action to reduce its consequences; when women present to antenatal clinic (ANC). MATERIALS AND METHODS: Cross-sectional descriptive this was an Interviewer-administered semi-structured questionnaire-based study of the anthropometric, and blood pressure measurementsin attendees at the postnatal clinic (PNC) of Jos University with ANC records. SETTING: Six weeks postnatal clinic (PNC) of Jos University Teaching Hospital (JUTH). RESULTS: The following indices proved predictive of HDP and subsequent hypertension: weight (P = 0.009), hip circumference (P = 0.018), parity (P = 0.043), waist circumference (P = 0.00), abdominal height (P = 0.040), waist/height (P = 0.020), history of developing hypertension in previous pregnancy (P = 0.000), birth weight of baby (P = 0.02), and mode of delivery (P = 0.05). CONCLUSION: To initiate preventive action on ANC registration in mitigating effects of or outrightly preventing HDP, careful check on anthropometry as well as history of hypertension or operative/preterm delivery in a previous pregnancy is necessary.

Clinical Outcomes in 3343 Children and Adults With Rheumatic Heart Disease From 14 Low- and Middle-Income Countries: Two-Year Follow-Up of the Global Rheumatic Heart Disease Registry (the REMEDY Study).

BACKGROUND: There are few contemporary data on the mortality and morbidity associated with rheumatic heart disease or information on their predictors. We report the 2-year follow-up of individuals with rheumatic heart disease from 14 low- and middle-income countries in Africa and Asia. METHODS: Between January 2010 and November 2012, we enrolled 3343 patients from 25 centers in 14 countries and followed them for 2 years to assess mortality, congestive heart failure, stroke or transient ischemic attack, recurrent acute rheumatic fever, and infective endocarditis. RESULTS: Vital status at 24 months was known for 2960 (88.5%) patients. Two-thirds were female. Although patients were young (median age, 28 years; interquartile range, 18-40), the 2-year case fatality rate was high (500 deaths, 16.9%). Mortality rate was 116.3/1000 patient-years in the first year and 65.4/1000 patient-years in the second year. Median age at death was 28.7 years. Independent predictors of death were severe valve disease (hazard ratio [HR], 2.36; 95% confidence interval [CI], 1.80-3.11), congestive heart failure (HR, 2.16; 95% CI, 1.70-2.72), New York Heart Association functional class III/IV (HR, 1.67; 95% CI, 1.32-2.10), atrial fibrillation (HR, 1.40; 95% CI, 1.10-1.78), and older age (HR, 1.02; 95% CI, 1.01-1.02 per year increase) at enrollment. Postprimary education (HR, 0.67; 95% CI, 0.54-0.85) and female sex (HR, 0.65; 95% CI, 0.52-0.80) were associated with lower risk of death. Two hundred and four (6.9%) patients had new congestive heart failure (incidence, 38.42/1000 patient-years), 46 (1.6%) had a stroke or transient ischemic attack (8.45/1000 patient-years), 19 (0.6%) had recurrent acute rheumatic fever (3.49/1000 patient-years), and 20 (0.7%) had infective endocarditis (3.65/1000 patient-years). Previous stroke and older age were independent predictors of stroke/transient ischemic attack or systemic embolism. Patients from low- and lower-middle-income countries had significantly higher age- and sex-adjusted mortality than patients from upper-middle-income countries. Valve surgery was significantly more common in upper-middle-income than in lower-middle- or low-income countries. CONCLUSIONS: Patients with clinical rheumatic heart disease have high mortality and morbidity despite being young; those from low- and lower-middle-income countries had a poorer prognosis associated with advanced disease and low education. Programs focused on early detection and the treatment of clinical rheumatic heart disease are required to improve outcomes.

The Cold Dusty Harmattan: A Season of Anguish for Cardiologists and Patients.

Human health and disease often demonstrate seasonal patterns. Knowledge of these aspects aids anticipation and planning. Numerous studies have shown that hypertension and cardiovascular diseases demonstrate a seasonal pattern. The Harmattan, the cold dusty season in Sub-Saharan Africa, is the season of greatest concern in this regard. In this commentary, the author draws on his and other researchers' studies to explain the grounds for onset and worsening of existing cardiovascular diseases. As implied in the title, it is a season that puts great strain on the cardiologist and the health system, as well as greater disease burden on the patient. This should be taken into consideration in planning and pooling of resources for effective patient management and mitigation of impact of disease.

Reversal of statin-induced memory dysfunction by co-enzyme Q10: a case report.

Statins are useful in the armamentarium of the clinician dealing with dyslipidemia, which increases cardiovascular morbi-mortality in hypertensive and diabetic patients among others. Dyslipidemia commonly exists as a comorbidity factor in the development of atherosclerotic cardiovascular disease. Use of statins is however associated with side effects which at times are so disabling as to interfere with activities of daily living. There are various ways of dealing with this, including use of more water-soluble varieties, intermittent dosing, or use of statin alternatives. Of late, use of co-enzyme Q10 has become acceptable for the muscle side effects. Only one report of any benefit on the rarely reported memory side effect was encountered by the author in the search of English medical literature. This is a report of a documented case of a Nigerian woman with history of statin intolerance in this case, memory dysfunction despite persisting dyslipidemia comorbidity. Her memory dysfunction side effect which interfered with activities of daily living and background muscle pain cleared when coenzyme Q10 was administered alongside low dose statin. Her lipid profile normalized and has remained normal. It is being recommended for use when statin side effects (muscle- and memory-related) impair quality of life and leave patient at dyslipidemia-induced cardiovascular morbi-mortality.

Relationship of blood pressure with some cardiovascular disease risk factors in a rural population of Plateau State, North Central Nigeria.

BACKGROUND: Hypertension is associated with certain cardiovascular disease (CVD) risk factors which vary from one place to the other depending on community sophistication. We decided to obtain the situation as it affects this rural Nigerian community to be in an evidence-based position to initiate individual and group prevention strategies. DESIGN: Cross-sectional population survey. MATERIALS AND METHODS: We surveyed for CVD risk factors among subjects 15 years and above in this rural community using a questionnaire requesting personal, medical and anthropometric information. One in three of them were randomly assigned to laboratory investigations. RESULTS: Of the 840 subjects studied, 25% were males. The population mean age was 45.5 (18.2) standard deviation (SD), with 1.8% smokers and 4.1% using alcohol. Systolic blood pressure (SBP) correlated with age, body mass index (BMI), total cholesterol (TC) and uric acid (UA); while diastolic blood pressure (DBP) correlated with age, BMI, TC, UA and atherogenic index (AI). SBP and DBP improved with exercise but not salt intake. The local seasonings used in cooking had no impact on blood pressure. CONCLUSION: To reduce cardiovascular morbidity in this and probably other rural sub-Saharan African communities, BMI, TC, UA and salt intake in diet should be targeted for reduction. Physical activity should be encouraged. Interestingly, these fall into the sphere of healthy lifestyle which should be encouraged and re-inforced.
