Sports anaemia and anthropometric evaluation of footballers at Kwame Nkrumah University of Science and Technology (KNUST)
Introduction: Sports anaemia is a physiological activity that occurs amongst footballers and may be due to poor diet, over-training, as well as an increase in plasma volume in endurance training activities. High plasma volume leads to changes in haematological parameters that may impact on endurance of footballers. The objective of the study was to determine the correlation between haematological and an-thropometric indices and their role in sports anaemia in a tropical setting. Methods: Venous blood was taken into EDTA for 12 soccer players of KNUST soccer team before training and after training for the first (W1) and fifth (W5) weeks of training sessions. Complete blood count analysis was done for each blood sample and anthropometric parameters such as height, weight, body mass index, body fat percent and lean body mass were also measured. Cross-tabulations with mean and standard deviation or median and range were computed. Paired t-test & and Mann-Whitney test for parametric and non-parametric data computations were carried out and a p-value β€ 0.05 was taken to rep-resent significant difference between data groups. Results: There was significant reduction in haemoglobin (p =0.003), haematocrit (p =0.002), mean cell volume (MCV) (p =0.034) and red blood cell (RBC) count (p=0.011) as a result of a significant expansion of plasma volume (p= 0.006). Neutrophil, lymphocyte and eosinophil counts were reduced significantly (p= 0.043, 0.001 and 0.007, respectively) after the training at W5. Lean body mass (LBM) inversely correlated with haemoglobin (r= -0.787, p= 0.002) and haematocrit (r= -0.588, p= 0.044). Body fat percentage (BFP) also negatively correlated with lymphocyte count (r= -0.700, p= 0.011). Furthermore, there was a positive correlation between body mass index (BMI) and plasma volume change after the training programme (r=0.689, p= 0.013). Conclusion: The results suggest that sports anaemia was induced by an increase in plasma volume that resulted in changes in haematological parameters.Pan African Medical Journal 2016; 2
Frequency and determinants of thyroid autoimmunity in Ghanaian type 2 diabetes patients: a case-control study
Left ventricular hypertrophy and insulin resistance in adults from an urban community in The Gambia: cross-sectional study.
To determine the association between left ventricular hypertrophy and insulin resistance in Gambians.Cross-sectional study.Outpatient clinics of Royal Victoria Teaching Hospital and Medical Research Council Laboratories in Banjul.Three hundred and sixteen consecutive patients were enrolled from outpatient clinics. The data of 275 participants (89 males) were included in the analysis with a mean (Β± standard deviation) age of 53.7 (Β±11.9) years.A questionnaire was filled and anthropometric measurements were taken. 2-D guided M-mode echocardiography, standard 12-1ead electrocardiogram, fasting insulin and the oral glucose tolerance test were performed.The Penn formula was used to determine the left ventricular mass index, 125 g/m2 in males and 110 g/m2 in females as the cut-off for left ventricular hypertrophy. Using the fasting insulin and fasting glucose levels, the insulin resistance was estimated by the homeostatic model assessment formula. Logistic regression analysis was used to determine the association between left ventricular hypertrophy and insulin resistance.The mean Penn left ventricular mass index was 119.5 (Β±54.3) and the prevalence of Penn left ventricular mass index left ventricular hypertrophy was 41%. The mean fasting glucose was 5.6 (Β±2.5) mmol/l, fasting insulin was 6.39 (Β±5.49) ΞΌU/ml and insulin resistance was 1.58 (Β±1.45). There was no association between Penn left ventricular mass index left ventricular hypertrophy and log of insulin resistance in univariate (ORβ=β0.98, 95% CIβ=β0.80-1.19, pβ=β0.819) and multivariate logistic regression (ORβ=β0.93, 95% CIβ=β0.76-1.15, pβ=β0.516) analysis.No association was found in this study between left ventricular hypertrophy and insulin resistance in Gambians and this does not support the suggestion that insulin is an independent determinant of left ventricular hypertrophy in hypertensives
Undiagnosed sub-valvular aortic stenosis with an associated Ventricular Septal Defect (VSD) presenting late in a multi-parous woman
Abstract Background Sub-valvular aortic stenosis is a rare disorder that has a prevalence of 6.5% of all adult congenital heart diseases. The hemodynamic changes that occur in pregnancy with the resultant increase in cardiac output may not well be tolerated by a pregnant woman with sub-valvular aortic stenosis. Case presentation We report the case of a 34-year-old para 7 (6 aliveβ+β1 dead) who has been experiencing intermittent episodes of easy fatigability on moderate exertion since childhood and had survived 6 prior pregnancies. During her last pregnancy, she started experiencing chest pain, palpitations, dyspnea, orthopnea, and pre-syncope at 36Β weeks and had a caesarean section at 37Β weeks on account of fetal distress. The post-delivery cardiac evaluation showed severe sub-valvular Aortic stenosis and a ventricular septal defect. Conclusion Sub-valvular Aortic stenosis may progress slowly in adults and may be tolerated during pregnancy. Despite the rare presentation and contraindication of pregnancy in such a patient, she extraordinarily survived the pregnancy with a healthy baby. Routine cardiovascular assessment during prenatal, ante-natal and post-natal care is highly advocated particularly so in resource-poor settings
Left ventricular hypertrophy among chronic kidney disease patients in Ghana
Introduction: The presence of left ventricular hypertrophy (LVH) in patients with Chronic Kidney Disease (CKD) is associated with worsening cardiovascular outcomes. There is a dearth of data on LVH in Ghanaian CKD patients. Methods: This was a cross sectional study carried out at the Komfo Anokye Teaching Hospital (KATH) in Kumasi, Ghana. A questionnaire was used to obtain information on clinical features of CKD. The MDRD-4 equation was used to calculate eGFR. Information on the prevalence and factors associated with electrocardiographic left ventricular hypertrophy were obtained during the initial assessment. Results: About 64.5% of the 203 participants were male and the mean age was 43.9 Β± 17.8 years. Most subjects (79.8%) had stage 5 disease. The mean systolic and diastolic blood pressures were 167.86 Β± 39.87 and 101.8 Β± 24.4 respectively. Approximately 43% of respondents had LVH. eGFR correlated negatively with LVH. High systolic pressure (OR 4.9, CI 2.4 β 10.4; p < 0.05), high diastolic pressure (OR 8.1, CI 4.0 β 16.1; p < 0.05) increased pulse pressure (OR 3.4 CI 2.6-9.3, p < 0.05), increased body mass index (OR 3.6 CI 1.7-11.2, p < 0.001) as well as male gender (OR 4.7, 95% CI 2.4 β 9.1; p <0.05) were associated with the presence of LVH.Conclusion: LVH is common in our cohort. High pulse pressure, high DBP, increased BMI and male gender are significant associated factors. Adequate treatment of high blood pressure as well as early detection of LVH and interventions aimed at prevention and/or regression of LVH are to be encouraged
