Abstract
Africa is gradually becoming the epicentre for the burden of cardiovascular diseases (CVDs) worldwide, and community-based data alluding to the pattern and dynamics of escalating epidemiological thresholds of CVDs among indigenous Africans are limited. This manuscript focuses on the design and methods of Community-based Investigation of the Risk Factors for Cardiovascular Diseases in Ibadan and suburbs (COMBAT-CVDs), an ongoing community-based door-to-door study assessing the profile, burden and dynamics of CVDs risk factors among residents of Ibadan and suburbs. COMBAT-CVDs is a cohort of community-dwelling indigenous Africans, males and females, ≥18years from ten communities in Ibadan, Nigeria. The recruitment of participants for the first wave (W0) started in 2020, covering; questionnaire administration and physical examination. The World Health Organization's STEPS Instrument for Chronic Disease Risk Factor Surveillance was used for data collection. Data were collected on sociodemographic, socioeconomic and lifestyle-related characteristics, history of CVDs, stress, depression and sleep quality. Also, anthropometric and blood pressure measures were conducted by trained personnel using standard operating procedures and instruments. Data collection for the second wave is underway, and the collection of blood and other biological samples for genetic epidemiology is planned, subject to availability of funds. For the W0 recruitment, a total of 3638 community-dwelling adults (males - 54.6% and females - 45.4%) participated with a ≥99.7% response rate. The COMBAT-CVDs will likely provide novel data, insightful characterization of CVDs risk factors and evidence for context-specific and culturally relevant interventions for the community-based prevention and management of CVDs among Africans in this setting.

Abstract
We investigated the toxic effect of nevirapine (NVP; Viramune®), an antiretroviral drug, on the liver, kidney and testis of Wistar rats. Twenty-one rats were assigned into 3 groups of 7 animals each. The first group served as control, and the second and third groups received NVP at 18 and 36 mg/kg body weight, respectively. Clinical signs of toxicity were not observed in the animals. NVP at both doses did not significantly ( p > 0.05) alter the body weight gain, relative weights of kidney and testis, serum protein, urea, creatinine and alkaline phosphatase levels of the animals. However, NVP2 significantly ( p < 0.05) increased the relative weight of liver, level of serum total bilirubin and activities of γ-glutamyl transferase, alanine and aspartate aminotransferases. NVP administration caused a dose-dependent, significant ( p < 0.05) elevation of lipid peroxidation measured as malondialdehyde (MDA) content in the liver, kidney and testis of the rats. Hepatic, renal and testicular MDA were increased by 107%, 80% and 163%, respectively, in NVP2-treated rats. Elevation in MDA was accompanied by a significant ( p < 0.05) decrease in the activities of hepatic, renal and testicular superoxide dismutase and catalase. NVP2 caused 43% and 32% decrease in spermatozoa motility and live/dead sperm count, respectively, and 94% increase in total sperm abnormalities. Histopathological findings showed that NVP2 caused degeneration of seminiferous tubules in testis, and severe necrosis in liver slides. NVP induced oxidative stress with corresponding decrease in antioxidant status of the rats. The changes in sperm parameters and, elevation of liver marker enzymes suggest an interference of NVP2 with these organs.
