Determinants of Child Mortality in Oyo State, Nigeria

This paper examined and identified some important determinants of infant and child mortality in Oyo state using Atiba Local Government as a case study. A total of 150 respondents were randomly selected from the entire populace in the metropolis. Logistic regression method was used to determine the factors that determine child mortality in the region. Findings reveals that out of the major determinants listed, Poverty, Malaria, Postnatal care, Health scheme and Breastfeeding are the major determinants of Child mortality in the state while HIV though catalyses child mortality was not a major determinant. It was therefore advised that policies should be revised for proper implementation and health intervention programmes that focus on mothers‟ and children‟s health should be strengthened to achieve the Millennium Development Goals (MDGs) of infant and child mortality in the remaining years. In addition, parents‟ economic conditions especially the father should be improved to encourage prolonged breast feeding.Key words: Infant mortality, child mortality, breastfeeding, Malaria, Povert

Poverty Alleviation Programmes and Economic Development in Nigeria: A Comparative Assessment of Asa and Ilorin West Local Govt. Areas of Kwara State, Nigeria

This study investigates into the impact of government programmes towards poverty alleviation on the inhabitants of Nigeria with special reference to Asa and Ilorin West Local Government Areas of Kwara State. A focus group discussion (FGD) of 4 groups (2 males and 2 females) was conducted from whose scenario a questionnaire was raised. Both qualitative and quantitative methods were employed especially to see the impact of those policies on the inhabitants using household income as a proxy. The Sen's Gini coefficient revealed that agricultural sector is the highest income-contributing sectorand worst hit income inequality group with about 84percent of totalpopulation in high poverty margin/region among the whole sectors studied. The study also acknowledged the existence of either one poverty alleviation program at one time or the other, but often the policy targets are at variance with the outcome. The study thus that suggests a kind of performance evaluation towards reappraising and adjusting the instruments employed by the programmes, refocus on the important sector(s) in the area of finance and credit facilities and organized buffer stock against agricultural s or bumper harvest in order to sustain price stability

Knowledge and use of emergency contraception by medical doctors on internship in a tertiary healthcare facility in Nigeria

Context: Emergency contraception (EC) is widely used to prevent unwanted pregnancy and it is largely adopted in many countries as over the counter drug to improve access.Aims: To determine and compare the correct knowledge, attitude and current use of EC among newly graduated medical doctors (MDs).Settings and Design: A cross.sectional study conducted among 255 newly graduated MDs at the University College Hospital, Ibadan, Nigeria.Materials and Methods: A pretested self.administered questionnaire was used to obtain data from consenting participants.Statistical Analysis Used: Descriptive, bivariate, and multivariable analyses were performed, and statistical significance was set at 0.05. Statistical Package for Social Science version 15.0 (Chicago, IL, USA) software was used.Results: The mean age of the respondents was 27.2 years (standard deviation = 2.1). The commonest indication for emergency contraceptive use mentioned was rape.96.5%. About 70% support EC in Nigeria, while about a quarter (26.9%) routinely counsel women about ECP use. About 21% of respondents currently use EC. Logistic regression analysis revealed significant results for gender [odds ratio (OR) =3.64; 95% confidence interval (CI) OR = 1.31.10.01), religion (OR = 0.26; 95% CI OR =  0.11.0.630) and marital status (OR = 0.19; 95% CI = 0.07.0.56). Conclusion: The correct knowledge and professional disposition toward EC as a form of contraception is low. We recommend that in.service training  should focus more on EC to improve the quality of their knowledge and  attitude towards it.Key words: Emergency contraception, knowledge, Medical Doctor, Nigeri

Evaluation of the concentration of toxic metals in cosmetic products in Nigeria

It has been shown that heavy metals toxicity to humans is as a result of long term or high level exposure to pollutants common in the environment including the air, water, food and numerous consumer products such as the cosmetics and toiletries. In this study, we assessed the levels of toxic metals in different cosmetic products sold at local shops in Lagos, Nigeria. The cosmetic items included thirty creams and twenty lipsticks and lip glosses. These items were purchased from various shops at different locations in Lagos. The cosmetics were analyzed for heavy metals (arsenic, cadmium, lead, mercury and nickel) after digestion with concentrated acids HNO3: H2SO4: HClO4 in ratio 2:2:1. The concentrations of the selected toxic heavy metals were determined in duplicate using a Buck 205 flame atomic absorption spectrophotometer. All the samples analyzed contained a detectable amount of all the metals of interest. The concentration of the heavy metals in the samples ranged from 0.006 to 0.207 ppm. It is obvious from the present study that the use of some cosmetic products exposes users to low concentrations of toxic heavy metals which could constitute potential health risk to users since it has been known that heavy metals can accumulate in the biological system over time and are known to induce skin problems or diseases such as cancer. Further research to better understand the sources of heavy metals in cosmetic products is recommended.Key words: Toxic heavy metals, cosmetics, atomic absorption spectrophotometer, environment

Iron indices in adults with sickle cell nephropathy in Lagos, Nigeria

Introduction: Although several studies have explored iron indices in patients with sickle cell anaemia (SCA), there is a paucity of evidence regarding the iron status of patients with sickle cell nephropathy (SCN). This study evaluated the range of iron status of adult SCA patients with or without nephropathy in Lagos, Nigeria.Methods: This was a cross-sectional study performed at the Sickle Cell Clinic of the Lagos University TeachingHospital (LUTH). Patients who were aged 18–65 years were assessed for SCN by determining the albumin-to creatinine ratio (UACR) on a spot urine sample, and determining the estimated glomerular filtration rate, using the CKD–EPI formula, on a steady-state serum creatinine concentration. Iron indices including serum ferritin, serum iron and total iron-binding capacity (TIBC) were measured, and percentage transferrin saturation (TSAT) was calculated. Data were analysed with the Statistical Package for the Social Sciences (SPSS) version 23. Results: A total of 200 patients were included, of whom 119 had SCN. There were no statistically significantdifferences in iron indices in participants with or without SCN. The median serum ferritin and TSAT of patients with SCN were 265 ng/mL and 31.8%, respectively, while the values were 255 ng/mL and 33.5% in those without SCN, respectively. Few participants were noted to have iron overload based on ferritin and TSAT values, regardless of SCN diagnosis. Although not statistically significant, females tended to have higher ferritin and serum iron values compared to males, irrespective of the presence or absence of SCN; whereas females without SCN had statistically significant higher TSAT values compared to males without SCN (36.2 ± 15.0% and 28.8 ± 11.5%, P = 0.03).Conclusion: Although iron overload is common in patients with SCA, our findings indicate that patients with SCNmay require routine evaluation of iron indices because few were iron overloaded. For this reason, the evaluation of iron indices in patients with SCN should be individualised to guide the direction of care and improve clinicaloutcomes. &nbsp

SmartEx: a case study on user profiling and adaptation in exhibition booths

An investigation into user profiling and adaptation with exhibition booth as a case study is reported. First a review of the field of exhibitions and trade fairs and a summary introduction to adaptation and profiling are given. We then introduce three criteria for the evaluation of exhibition booth: effectiveness, efficiency and affect. Effectiveness is related the amount of information collected, efficiency is a measurement of the time taken to collect the information, and affect is the perception of the experience and the mood booth visitors have during and after their visit. We have selected these criteria to assess adaptive and profiled exhibition booths, we call smart exhibition (SmartEx). The assessment is performed with an experiment with three test conditions (non-profiled/non adaptive, profiled/non-adaptive and profiled adaptive presentations). Results of the experiment are presented along discussion. While there is significant improvements of effectiveness and efficiency between the two-first test conditions, the improvement is not significant for the last test condition, for reasons explained. As for the affect, the results show that it has an under-estimated importance in people minds and that it should be addressed more carefully

Multimodality Imaging of Abnormal Vascular Perfusion and Morphology in Preclinical 9L Gliosarcoma Model

This study demonstrates that a dynamic susceptibility contrast-magnetic resonance imaging (DSC-MRI) perfusion parameter may indicate vascular abnormality in a brain tumor model and reflects an effect of dexamethasone treatment. In addition, X-ray computed tomography (CT) measurements of vascular tortuosity and tissue markers of vascular morphology were performed to investigate the underpinnings of tumor response to dexamethasone.One cohort of Fisher 344 rats (N = 13), inoculated intracerebrally with 9L gliosarcoma cells, was treated with dexamethasone (i.p. 3 mg/kg/day) for five consecutive days, and another cohort (N = 11) was treated with equal volume of saline. Longitudinal DSC-MRI studies were performed at the first (baseline), third and fifth day of treatments. Relative cerebral blood volume (rCBV) was significantly reduced on the third day of dexamethasone treatment (0.65 ± .13) as compared to the fifth day during treatment (1.26 ±.19, p < 0.05). In saline treated rats, relative CBV gradually increased during treatment (0.89 ±.13, 1.00 ± .21, 1.13 ± .23) with no significant difference on the third day of treatment (p>0.05). In separate serial studies, microfocal X-ray CT of ex vivo brain specimens (N = 9) and immunohistochemistry for endothelial cell marker anti-CD31 (N = 8) were performed. Vascular morphology of ex vivo rat brains from micro-CT analysis showed hypervascular characteristics in tumors, and both vessel density (41.32 ± 2.34 branches/mm(3), p<0.001) and vessel tortuosity (p<0.05) were significantly reduced in tumors of rats treated with dexamethasone compared to saline (74.29 ± 3.51 branches/mm(3)). The vascular architecture of rat brain tissue was examined with anti-CD31 antibody, and dexamethasone treated tumor regions showed reduced vessel area (16.45 ± 1.36 µm(2)) as compared to saline treated tumor regions (30.83 ± 4.31 µm(2), p<0.001) and non-tumor regions (22.80 ± 1.11 µm(2), p<0.01).Increased vascular density and tortuosity are culprit to abnormal perfusion, which is transiently reduced during dexamethasone treatment
