Background.Cyclophosphamide (CP) is a nitrogen mustard alkylating drug used for the treatment of chronic and acute malignant lymphomas, myeloma, leukemia, neuroblastoma, adenocarcinoma, retinoblastoma, breast carcinoma, and immunosuppressive therapy. Despite its vast therapeutic uses, it is known to cause severe cardiac toxicity. Kolaviron (KV), a Garcinia kola seed extract containing a mixture of flavonoids, is reputed for its antioxidant and membrane stabilizing properties.Objective.This study investigated the protective effect of KV on CP-induced cardiotoxicity in rats.Methods.Thirty rats were used, and they were divided into 6 groups of 5 rats each. Group I received 2 mL/kg propylene glycol orally for 14 days; group II received CP (50 mg/kg/d, intraperitoneally [i.p.]) for 3 days; groups III and IV received 200 and 400 mg/kg/d KV, respectively, orally for 14 days and groups V and VI were pretreated with 200 and 400 mg/kg/d KV, respectively, orally for 14 days followed by CP (50 mg/kg/d, i.p.) for 3 days.Results.CP treatment resulted in a significantly lower food consumption and body weight in rats. The lactate dehydrogenase and creatine kinase enzymes in cardiac tissues of rats treated with CP were significantly higher. In cardiac tissues, 3-day doses of CP resulted in significantly higher heart weight, cardiac troponin I, myeloperoxidase, malondialdehyde, hydrogen peroxide and lower superoxide dismutase, catalase, glutathione peroxidase activities, and reduced glutathione levels. Histological examination of cardiac tissues showed sign of necrosis of myocardium after CP treatment. However, administration of KV at 200 and 400 mg/kg for 14 days prior to CP treatment, increase food consumption, body weight, and attenuates the biochemical and histological changes induced by CP.Conclusions.These results revealed that KV attenuates CP-induced cardiotoxicity by inhibiting oxidative stress and preserving the activity of antioxidant enzymes.

Background: Abnormal body mass index (BMI) is known to result in serious health consequences. Objective: The present study aimed at determining the pattern and prevalence of underweight, overweight and obesity among market women at Ile-Ife. Methods: The participants had their weight and height recorded by standardised techniques, and BMI was calculated from the weight and height. BMI was classified according to the World Health Organization criteria. The average income per day (AIPD) for each participant was estimated as the average sum of daily profit earned on goods and services. Data were analysed using descriptive and inferential statistics. Results: Nine hundred and three market women participated in the present study. The age range was 18–95 years with 41.7% between 18 and 40 years, 43.0% between 41 and 64 years and 15.3% were 65 years and above. The mean of age and BMI of the participants were 46.3 (15.1) years and 28.5 (5.4) kg/m2, respectively. Only 23.3% of the women had normal BMI. The prevalence of underweight, overweight and obesity was 1.7%, 38.5% and 36.5%, respectively. The distribution of overweight and obesity among age groups 18–40 years, 41–64 years and 65 years and above was 40.6% and 30.2%; 38.7% and 41.7% and 32.6% and 39.1%, respectively. There was a significant association (χ2 = 7.177, P = 0.028) between AIPD and BMI classes. Conclusion: This study showed a high prevalence of abnormal BMI among market women in Ile-Ife. Overweight and obesity constitute a major health burden among market women.

Background: Sex verification using electrocardiogram (ECG) is a new application of the biological signal. Objective: This study aimed to determine the sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of an electrocardiographic score in sex verification. Methods: A total of 2442 apparently healthy fresh undergraduates who presented for health screening in a tertiary institution were recruited for the study. The technical team documented the sex of the participants and had their resting 12-lead ECG recorded according to standard protocol. Two physicians who were blinded to the participants and the recorded sex utilized Ogunlade Sex Determination Electrocardiographic Score (OSDES) to determine the sex. The validity of OSDES was estimated using sex recorded by the technical team as the standard while the accuracy of scoring system was determined using receiver operating characteristic curve. Results: The mean (± standard deviation) of age of the participants was 20.71 ± 3.62 years. Among the male population, true positives (TPs), false positives (FPs), false negatives (FNs), and true negatives (TN) were 1131, 49, 90, and 1172, respectively. Among the females TP, FP, FN, and TN were 1172, 90, 49, and 1131, respectively. Among males, the sensitivity, specificity, PPV, and NPV were 92.63% (95% confidence interval [CI]: 91.02-94.03%), 95.99% (95% CI: 94.73-97.02%), 95.85% (95% CI: 94.55-96.91%), and 92.87% (CI: 91.31-94.23%) respectively while among the females, the sensitivity, specificity, PPV, and NPV were 95.99% (95% CI: 94.73-97.02%), 92.63% (95% CI: 91.02-94.03%), 92.87% (95% CI: 91.31-94.23%), and 95.85% (95% CI: 91.02-94.03%) respectively. The area under curve was 0.943. Conclusion: This study concluded that ECG has a reasonable level of sensitivity and specificity with excellent accuracy in verification of sex among fresh Nigerian undergraduates.

Background: There are evidences to suggest that the World Health Organization (WHO) general cutoff points for body mass index (BMI) may not be the most appropriate for young adults globally irrespective of racial and ethnic considerations. Objective: This study assessed body anthropometric parameters in healthy population of young adult Nigerians with a view to determining race and gender-specific criteria (Ife criteria) for BMI classification. Methods: Four hundred and eighty-four (242 males and 242 females) healthy subjects aged between 18 and 41 years (inclusive) were recruited for the study. The participants were age- and sex-matched (mean age: 22.81 ± 3.83 years). The weight and height of the subjects were obtained using standard techniques while BMI was calculated as derivatives of height and weight. The BMI was classified using 5 th , 85 th , and 95 th percentiles and delineated into underweight ( 95 th percentile). Results: The result showed that the general BMI cutoff values for underweight, normal, overweight, and obesity were Conclusions: The cutoff values for the new criteria for BMI classification were lower than the WHO defined values and sex differences were demonstrated in BMI. Therefore, WHO criteria may not be universally applicable.
