- "INTRODUCTION:The clinical and public health implications of the convergence of the human immunodeficiency virus (HIV) epidemic and chronic viral hepatitis in sub-Saharan Africa are poorly understood. This study was designed to determine the seroprevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV), and the impact of co-infection on baseline serum alanine transaminase (ALT), CD4+ T lymphocyte (CD4) count, and plasma HIV-RNA (viral load) in a cohort of HIV-infected Nigerians. METHODS:A retrospective study was conducted, on eligible treatment-naive patients who presented between August 2004 and February 2007 to the University College Hospital (UCH), Ibadan, Nigeria. Demographic data and pre-treatment laboratory results (hepatitis B surface antigen (HBsAg), HCV antibodies (anti-HCV), ALT, CD4 count and viral load) were retrieved from the medical records. Fisher's exact, two sample t-tests, and the Wilcoxon rank sum tests were used to compare groups. A logistic regression model was fitted to explore characteristics associated with co-infection status. RESULTS:A total of 1779 HIV-infected patients (male: female ratio, 1:2) met inclusion criteria. HBsAg was present in 11.9%, anti-HCV in 4.8% and both markers in 1%. HBsAg was more common among males than females (15.4% vs 10.1%, respectively p = 0.001) while anti-HCV was detected in a similar proportion of males and females (5.3% versus 4.6%, respectively p = 0.559). HIV-infected patients with anti-HCV alone had a lower mean baseline CD4 count compared to those without anti-HCV or HBsAg (197 cells/mm3 vs 247 cells/mm3, respectively p = 0.008). Serum ALT was higher among patients with HBsAg compared to those without HBsAg or anti-HCV (43 International Units (IU) vs. 39 IU, respectively p = 0.015). Male gender was associated with HBV co-infection on logistic regression (OR1.786; 95% CI, 1.306-2.443; p < 0.005). CONCLUSION:More HIV-infected females than males presented for care in this cohort. We identified a relatively high prevalence of HBV and HCV co-infection in general, and a higher rate of HBV co-infection among males than females. Pre-treatment CD4 count was significantly lower among those with HCV co-infection, while ALT was slightly higher among those with HBV co-infection. Triple infection with HIV, HBV and HCV was present in a small but significant proportion of patients. These findings underscore the importance of testing for HBV and HCV in all HIV-infected persons in our setting." 2 results 2
- A study was conducted in Ibadan, South-West Nigeria between 2005 and 2009 to determine the prevalence, risk factors and management protocols employed in earfly bite wounds in dogs. Review of case records, physical examinations and administration of structured questionnaire were used to obtain information with regard to the number of cases of earfly bite wounds presented, signalment, anatomical features, treatment modalities and response. Prevalence of earfly bite wounds was 11.73%. Sex, breed, anatomical features and management exhibited significant influence on the incidence of earfly bite wounds. Effectiveness of management protocols was low with significantly high recurrence rate. The results showed a significantly high association between earfly bite wounds and aural hematoma and otitis externa. 2 results 2

- Background: Many patients are referred to labour ward as emergencies, and therefore do not benefit from the antenatal HIV counselling and testing and treatment offered to registered patients. Objective: To assess the acceptability and suitability of offering HIV counselling and testing to women of unknown HIV status presenting in labour. Methods: A cross-sectional study comprising counselling and obtaining consent for HIV testing among 104 unregistered patients who presented in labour over a 3-month period. Rapid and enzyme-linked immunosorbent assay screening was performed for 90 consenting respondents. Reactive results were confirmed by Western blot. Appropriate therapy was instituted. Results: Acceptance rate for HIV testing was 86.5%, prevalence of HIV was 6.7%. Women of lower educational status were more likely to accept testing in labour (OR: 0.3; 95% CI: 0.1-0.7; p=0.01); age, parity, occupation and knowledge of HIV had no influence. Most women (66.3%) had satisfactory knowledge of HIV. No one admitted to feeling coerced to test in fear of being denied care. Most refusals for screening were to avoid needle pricks (28.6%). Compared to ELISA screening test, specificity of the rapid test was 100%, sensitivity 85.7%, positive predictive value 100% and negative predictive value 98.8%. Attitude to testing was maintained on post-partum re-evaluation. Conclusion: The prevalence of HIV amongst unregistered parturients showed the importance of offering point-of-care HIV testing and intervention, especially in an environment where antenatal clinic attendance is poor. Rapid testing appeared to be acceptable and feasible in labour to prevent the mother-to-child transmission of HIV. 2 results 2
- Background: Nigeria has the largest paediatric HIV-infected population in the world. Missed opportunities for prevention of mother-to-child transmission of HIV (PMTCT) compromise efforts at eliminating new pediatric HIV infections. Methods: Six hundred children, aged < 15 years, presenting to the pediatric units of the University College Hospital (UCH), Ibadan Southwest Nigeria between June to December 2007 were studied. The demographics, HIV status and socioeconomic status of mothers and their children were studied. A 4-step hierarchy was used to assess the missed opportunities for PMTCT. Step 1: utilization of a health facility for antenatal care and delivery; Step 2: maternal HIV status determination during pregnancy; Step 3: provision of antiretroviral medication to HIV-infected mother and baby; and Step 4: avoidance of mixed feeding in HIV-exposed children. The rates of missed opportunities for PMTCT services at different steps in the PMTCT cascade, perinatal transmission rates, and associated factors were reported. Results: There were 599 mothers and 600 children (one set of twins), 60 (10%) were HIV infected and 56 (93.3%) of these were adjudged perinatally infected. Of 78 HIV-infected women, 7 (9.0%) accessed all interventions in the PMTCT cascade and 71 (91.0%) had missed opportunities for PMTCT. Missed opportunities for PMTCT occurred 42.9% in cascade Step 1, 64.2% in Step 2, 52.6% in step 3 and 73.7% in Step 4. All mother-baby pairs who accessed complete PMTCT interventions received care at a teaching hospital. Among infants with perinatal HIV infection, 53 (94.6%) were born to mothers who had missed opportunities for PMTCT. Most women with missed opportunities attended antenatal care outside the teaching hospital setting and belonged to low socioeconomic status. Conclusion: It is imperative to expand PMTCT access to women who receive antenatal care outside the teaching hospitals and to those of low socioeconomic status. 2 results 2

- This paper presents the application of Artificial Neural Network (ANN) in modeling the heat transfer coefficient of a staggered multi-row, multi-column, cross-flow, tube-type heat exchanger. Heat transfer data were obtained experimentally for air flowing over a bank of copper tubes arranged in staggered configuration with 5 rows and 4 columns at different air flow rates with throttle valve openings at 10 - 100%. The Reynolds number and the row number were used as input parameters, while the Nusselt number was used as output parameter in training and testing of the multi-layered, feed-forward, back-propagation neural networks. The network used in this study was designed using the MATLAB® Neural Network Toolbox. The results show that the accuracy between the neural networks predictions and experimental values was achieved with Mean Absolute Relative Error (MRE) less than 1 and 4% for the training and testing data sets respectively, suggesting the reliability of the networks as a modeling tool for engineers in preliminary design of heat exchangers. 2 results 2
- This study was conducted to determine the malariometric indices of children in three different settings in Ibadan,Nigeria. Children were recruited from an urban slum (Oloomi) and a periurban (Sasa) and a rural community (Igbanda) in Ibadan. Children aged between 2 and 10 years were randomly selected from primary schools in the urban and periurban areas. In the rural community, children were recruited fromthe centre of the village. A total of 670 (55.0%) out of 1218 children recruited were positive formalaria parasitaemia.The urban population had the highest proportion of children with malaria parasitaemia. Splenomegaly was present in 31.5%, hepatomegaly in 41.5%, hepatosplenomegaly in 27.5%, and anaemia in 25.2% of the children.The parasite density was not significantly different among children in the three communities. Children in the rural community had the highest mean PCV of 34.2% and the lowest rates of splenomegaly (6.1%), hepatomegaly (7.6%), and hepatosplenomegaly (4.6%).The spleen rates, liver rates, and presence of hepatosplenomegaly and anaemia were similar in the urban and periurban communities.The malariometric indices among the asymptomatic carriers were high, especially in the urban slum. This stresses the need for intensified efforts at controlling the disease in the study area. 2 results 2
