Assessment of Protein C and Protein S of Pregnancy Loss Victims

Abstract: Background: The haemostatic changes that result in thrombophilia during the pregnant state have been linked to pregnancy loss. Objective: Assessment of Protein S, and Protein C assays in pregnancy loss victims in Abia State, South East, Nigeria. Materials and Methods: This was a cross-sectional study involving women in their reproductive years. Study population was stratified into 3 groups and the Protein C and Protein S concentrations measured and compared among the three groups. Results: A total of 130 apparently healthy Nigerian women of child-bearing age were enrolled in the study. The study groups consisted of 70 women who had just lost a pregnancy, 30 women with normally progressing pregnancy and 30 nonpregnant women. The protein C concentration for the pregnancy-loss subjects was significantly lower than that of the normal pregnancy at p ≤ 0.01 while that of Protein S showed non-significance (p > 0.05). Conclusion: Protein C deficiency is associated with increase in pregnancy loss.

Antimicrobial Susceptibility Pattern of Klebsiella pneumonia and Escherichia coli Isolated from Stool Samples of Patients in Two Tertiary Hospitals in Rivers State, Nigeria

Abstract: Reduced susceptibility of antibiotics against Enterobacterial strains have emerged as an important public health problem worldwide. Infections caused by Escherichia coli and Klebsiella pneumonia can affect severely ill patients, and their colonization of human gut, endangers population at large in communities, and in hospitals. This research is aimed at determining the susceptibility pattern of Escherichia coli and Klebsiella pneumonia from stool of patients in two tertiary hospitals in Rivers State, Nigeria. A total of 114 stool samples were collected from patients. Stool samples were collected in sterile biological specimen bottles and were sent to the laboratory immediately after collection. Stool samples were inoculated by streaking on Eosin methylene blue and MacConkey agar plates. Isolates were characterized using standard microbiological methods and were stored and used for further tests. The result showed that nineteen isolates of E. coli were 100% resistant to Cefuroxime and Augmentin, while 78.9%, 68.4% and 42.1% were resistant to cefixime, Original Research Article Douglas et al.; SAJRM, 6(1): 44-49, 2020; Article no.SAJRM.55852 45 Ceftazidime and Nitrofurantoin, respectively. The result for the susceptibility pattern of the Klebsiella isolates showed 100% resistance to cefuroxime and Augmentin. Resistance to ceftazidime, cefixime and nitrofurantoin were observed to be 70%, 60% and 45%, respectively. Isolates of E. coli and Klebsiella were highly susceptible to Meropenem and ofloxacin. The isolates of E. coli and Klebsiella showed multi-drug resistance to the different antibiotics. Although the meropenem, ofloxacin and ciprofloxacin antibiotics showed high level of sensitivity to these isolates, there were still some level of resistance recorded.

Determination of Geothermal Gradient from Bore Hole Temperature data in Some Parts of the Eastern Niger Delta Basin

Abstract: An analysis of Geothermal Gradients in the Eastern Niger Delta basin was done using Bore Hole Temperature (BHT) data from three (3) adjacent oil fields. BHT data was converted to static formation temperature by using the conventional method of increasing measured BHT data by 10% and Geothermal Gradient computed using its simple linear relationship with depth, surface temperature and static temperature at depth. Projections were then made for change in Geothermal gradients at 1km intervals to a depth of 4 km. Results obtained showed significant variations across Idama, Inda and Robertkiri fields with average geothermal gradients of 17.3⁰C/Km, 22.6⁰C/Km and 23.1⁰C/Km respectively. Variation in the geothermal gradients in the area is attributed to lithological control and differential rates of sedimentation during basin evolution. Also, results showed that the Geothermal Gradient in the area are generally moderate and could be a good reason for the occurrence of more oil hydrocarbons than gas in the area.

Infection status of school children with Schistosoma haematobium in an urban setting in South-eastern Nigeria

Abstract: A study on Schistosoma haematobium among school age children in the urban area of Abiriba in Abia State, Eastern Nigeria, was conducted between February and July 2009. Urine samples were collected and analysed for eggs of S. haematobium by microscopy using the centrifugation method. The result showed an overall prevalence of S. haematobium infection to be 40.8%. More males (62.3%) were infected than females (37.7%). The difference was not statistically significant (p > 0.05). The level of infection was reliably predicted using the logistic regression model, varied from school to school. Altogether, 390 (63.3%) of the infected individuals had a light infection. Urine samples of 408 individuals were found to be positive for both S. haematobium ova and visible haematuria, while urine samples of 162 individuals were positive only for S. haematobium but devoid of haematuria. S. haematobium was found to be the highest among the school children aged 11–14. In conclusion, S. haematobium is endemic in the...
