COMPARATIVE EVALUATION OF VARIETIES OF COWPEA AND ITS EFFECT ON FERTILTY STATUS OF LATERITIC SOIL OF LANDMARK UNIVERSITY

Identification of cowpea varieties with superior grain yield and high soil fertility enhancing potential is crucial to increasing productivity of the crop among small-scale farmers in Omu-Aran, Kwara State. A field experiment was carried out during the 2014 growing season to evaluate two cowpea varieties for their grain yield and their effect on fertility status of Lateritic soils of Landmark University Teaching and Research Farm. The varieties evaluated were IAR 48 and IAR 2.5.6. Variety IAR 2.5.6 produced the highest grain yield compared to variety IAR 2.5.6. The study also revealed the potential of cowpea in improving the fertility status of Lateritic soils as there was significant difference observed in some of the chemical properties analyzed including available Phosphorus, Exchangeable Calcium, Magnesium, Potassium and Sodium

Intrapartum prediction of birth weight using maternal anthropometric measurements and ultrasound scan

This prospective study was conducted at Federal Medical Centre, Owo, Nigeria, between April 1st and 31st of July, 2013 to predict birth weight in labour using four clinical methods and ultrasound scan independently and comparatively to determine which is closest to the actual birth weight. The four clinical methods are Ojwang's formula, Johnson's formula, 5% of maternal weight and 10% of maternal body mass index. A total of 100 women who fulfilled the inclusion criteria had their foetal weight estimated using the methods. Accuracy of the prediction was determined by mean weight difference, percentage error and proportion of estimates within 10% of actual birth weight.Tests of significant difference were done and the level of significance was set at 0.05.Correlation and regression analyses were carried out.Of the five methods used, ultrasound scan estimation had the highest correlation coefficient of 0.681(P<0.001) followed by Ojwang's rule with correlation coefficient of 0.675(P<0.001). The prediction using Johnson's method performed next to Ojwang's rule with correlation coefficient of 0.629(P<0.001).The methods using 5% maternal weight and 10% maternal BMI had correlation coefficients of 0.312(P<0.001) and 0.220(P<0.001) respectively. It was then concluded that there is positive significant correlation between the methods used and actual birth weight. The method using 10% maternal BMI is the least reliable while the ultrasound scan estimate was the most reliable. Ojwang's rule estimation performed next to ultrasound and should be considered first in settings where ultrasound machine or the expertise to use the machine is lacking.Keywords: Birth weight, Foetal weight, Ultrasonography, Pregnancy, Delivery, Prospective studie

Correlation between placenta and umbilical cord morphplogy and perinatal outcome in singleton deliveries at term in a Nigerian tertiary health centre

Context: The ability of the fetus to grow and thrive in-utero depends on a number of factors of which the placenta is a contributor. The umbilical cord is an essential organ connecting the fetus to the placenta and a healthy placenta is essential for good perinatal outcome.Objectives: The study aims at determining the relationship between the morphology of the placenta and umbilical cord and perinatal outcome in singleton deliveries at term in a Nigerian hospital.Study design:This is a cross-sectional study involving the analysis of placentae and umbilical cords of three hundred and five neonates delivered in the Federal Medical Centre, Owo who met the inclusion criteria. Immediately after each delivery, the umbilical cord was clamped and severed five centimetres from its attachment to the neonate. The rest of the umbilical cord from the cut end to its insertion on the placenta was measured in centimetres and five centimetres of the umbilical cord attached to the neonate was added to get the entire length of the umbilical cord. Other parametersinvolving the morphology of the umbilical cord and placentae were also noted.Outcome measures: Correlation between the morphological parameters of the umbilical cord, placenta and the neonatal factors such as Apgar scores, birth weight, length of the baby, admission into Neonatal Intensive Care Unit and its indication were determined.Results: Three hundred and five women had their babies' placentae and umbilical cords examined and also had other records complete. There were 270 umbilical cords out of the 305 recruited with normal coiling index range of 0.17-0.20 coils per centimetres giving an incidence of 88.5%. There was a positive correlation between birth weight and placenta weight (r = 0.466; p value <0.001); there was also a positive correlation between birth length and umbilical cord length (r = 0.130; p value <0.024); likewise there was a positive correlation between umbilical cord coiling index and some parameters of assessing perinatal outcome like the Apgar scores at first and fifth minute (r = 0.137; p value 0.024 and r = 0.84; p value 0.167 respectively) while it had a negative correlation with birth weight (r = -0.130;p = 0.024) .Conclusion: The findings from this study contribute significantly to knowledge and have also helped to establish the correlation between the intrauterine and extrauterine wellbeing

A Systematic Review and Meta-Analysis of Fecal Contamination and Inadequate Treatment of Packaged Water

<div><p>Background</p><p>Packaged water products provide an increasingly important source of water for consumption. However, recent studies raise concerns over their safety.</p><p>Objectives</p><p>To assess the microbial safety of packaged water, examine differences between regions, country incomes, packaged water types, and compare packaged water with other water sources.</p><p>Methods</p><p>We performed a systematic review and meta-analysis. Articles published in English, French, Portuguese, Spanish and Turkish, with no date restrictions were identified from online databases and two previous reviews. Studies published before April 2014 that assessed packaged water for the presence of <i>Escherichia coli</i>, thermotolerant or total coliforms were included provided they tested at least ten samples or brands.</p><p>Results</p><p>A total of 170 studies were included in the review. The majority of studies did not detect fecal indicator bacteria in packaged water (78/141). Compared to packaged water from upper-middle and high-income countries, packaged water from low and lower-middle-income countries was 4.6 (95% CI: 2.6–8.1) and 13.6 (95% CI: 6.9–26.7) times more likely to contain fecal indicator bacteria and total coliforms, respectively. Compared to all other packaged water types, water from small bottles was less likely to be contaminated with fecal indicator bacteria (OR = 0.32, 95%CI: 0.17–0.58) and total coliforms (OR = 0.10, 95%CI: 0.05, 0.22). Packaged water was less likely to contain fecal indicator bacteria (OR = 0.35, 95%CI: 0.20, 0.62) compared to other water sources used for consumption.</p><p>Conclusions</p><p>Policymakers and regulators should recognize the potential benefits of packaged water in providing safer water for consumption at and away from home, especially for those who are otherwise unlikely to gain access to a reliable, safe water supply in the near future. To improve the quality of packaged water products they should be integrated into regulatory and monitoring frameworks.</p></div
