Ibadan, Nigeria

The University of Ibadan is the oldest and one of the most prestigious Nigerian universities, and is located five miles from the centre of the major city of Ibadan in Western Nigeria.Besides the College of Medicine, there are now ten other faculties: Arts, Science, Agriculture and Forestry, Social science, Education, Veterinary Medicine, Technology, Law, Public Health and Dentistry.The University has residential and sports facilities for staff and students on campus, as well as separate botanical and zoological gardens.

Maternal oxygen administration has been used in an attempt to lessen fetal distress by increasing the available oxygen from the mother. This has been used for suspected fetal distress during labour, and prophylactically during the second stage of labour on the assumption that the second stage is a time of high risk for fetal distress. The objective of this review was to assess the effects of maternal oxygenation for fetal distress during labour and to assess the effects of prophylactic oxygen therapy during the second stage of labour on perinatal outcome. We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (22 October 2012) and searched reference lists of retrieved studies. Randomized trials comparing maternal oxygen administration for fetal distress during labour and prophylactic oxygen administration during the second stage of labour with a control group (dummy or no oxygen therapy). Both review authors assessed eligibility and trial quality. Data were extracted, checked and entered into Review Manager software. For dichotomous data, we calculated relative risks (RR) and 95% confidence intervals (CI). For continuous data, we calculated weighted mean differences and 95% CI. We located no trials addressing maternal oxygen therapy for fetal distress. We included two trials which addressed prophylactic oxygen administration during labour. Abnormal cord blood pH values (less than 7.2) were recorded significantly more frequently in the oxygenation group than the control group (RR 3.51, 95% CI 1.34 to 9.19). There were no other statistically significant differences between the groups. There were conflicting conclusions on the effect of the duration of oxygen administration on umbilical artery pH values between the two trials. Implications for practice There is not enough evidence to support the use of prophylactic oxygen therapy for women in labour, nor to evaluate its effectiveness for fetal distress.Implications for research In view of the widespread use of oxygen administration during labour and the possibility that it may be ineffective or harmful, there is an urgent need for randomized trials to assess its effects.

This study investigates the relationship between oil prices and returns on the Nigerian Stock Exchange. By using GARCH-jump models, we are able to model the volatility of stock returns and also take account of the effect of extreme news events on returns. The empirical results show a negative but insignificant effect of oil prices on stock returns in Nigeria. Possible explanations for this result could be because the stock exchange is dominated by the banking sector and there are too few oil-related firms to warrant a channelling of high oil prices to the stock market; or because of the high transactions costs on the stock exchange which discourages investment; or because of low liquidity on the stock exchange. © 2013 Elsevier Ltd.

Background Hypertension was once considered rare in sub-Saharan Africa (SSA), but currently it has become a widespread problem with immense socioeconomic importance. The purpose of this review is to summarise new information on hypertension in SSA that has been published since the last major review in 2008. Methods and results A literature search was performed in Pubmed, Embase, WHO Global Cardiovascular Infobase, African Journal On-Line, and African Index Medicus using the following search criteria: hypertension, high blood pressure, and Africa/ SSA. Epidemiological surveys that used the WHO STEPS approach or similar methods were also included. The overall prevalence of hypertension in SSA was estimated at 16.2% (95% CI 14.2% to 20.3%) with an estimated number of hypertensive individuals to be 74.7 million. The prevalence of hypertension varies widely from country to country. It is projected that the number of affected individuals will increase by 68% (125.5 million) by 2025. Mass migration of rural Africans to urban areas and rapid changes in lifestyle and risk factors account for the rising prevalence of hypertension. Conclusions Proactive public health interventions at a population level need to be introduced to control the growing hypertension epidemic, and there needs to be a major improvement in access to hypertensive care for the individual. There is an important need for better epidemiological data and hypertension related outcome trials in SSA. Source

Modelling and prediction of wind speed are essential prerequisites in the sitting and sizing of wind power applications. The profile of wind speed in Nigeria is modelled using artificial neural network (ANN). The ANN model consists of 3-layered, feed-forward, back-propagation network with different configurations, designed using the Neural Toolbox for MATLAB. The monthly mean daily wind speed data monitored at 10 m above ground level for a period of 20 years (1983-2003) for 28 ground stations operated by the Nigeria Meteorological Services (NIMET) were used as training (18 stations) and testing (10 stations) dataset. The geographical parameters (latitude, longitude and altitude) and the month of the year were used as input data, while the monthly mean wind speed was used as the output of the network. The optimum network architecture with minimum Mean Absolute Percentage Error (MAPE) of 8.9% and correlation coefficient (r) between the predicted and the measured wind speed values of 0.9380 was obtained. The predicted monthly wind speed ranged from 0.9-13.1 m/s with an annual mean of 4.7 m/s. The model predicted wind speed values are given in the form of monthly maps, which can be easily used for assessment of wind energy potential for different locations within Nigeria. © 2009 Elsevier Ltd.

Background: In order to improve post-stroke health-related quality of life (HRQOL), it is crucial to focus scarce health care and research resources towards its consistent determinants. Disparities in reported determinants of post-stroke HRQOL may be due to the use of different instruments (generic or specific) in different populations. This is the first study to identify factors which consistently influenced both generic and specific post-stroke HRQOL in the same study population. Methods: One hundred consecutive consenting stroke survivors were assessed using the stroke levity scale (SLS), modified Rankin scale (mRS), SF-36 and HRQOL in stroke patients (HRQOLISP) measure. Employing multiple regression analysis (R2 = 0.63), potential predictors were sought among age, gender, socioeconomic class (SEC), aphasia, post-stroke duration, side, type and number of strokes, SLS, mRS, social support and Likert scale-graded responses to laughter and negative-feeling frequency. Results: Gender, SEC and stroke type had no significant impact on HRQOL. The consistent independent statistical predictors of several facets of generic and stroke-specific HRQOL were stroke severity, disability, laughter and negative-feeling frequencies. Conclusions: While stroke severity, a component of physical health, impaired psychological health, psychological dysfunction in turn negatively influenced physical and other domains of health, thereby creating a vicious cycle. These multidirectional interactions may involve neural, social and existential mechanisms which remain to be confirmed, elucidated and exploited. Copyright © 2009 S. Karger AG, Basel. Source
