Health (Health) , 2015, DOI: 10.4236/health.2015.74054
Abstract: Objectives: The objectives of this study were to estimate the prevalence of the HBV infection in Jazan, Kingdom of Saudi Arabia (KSA) and to correlate serologic findings with epidemiological data and known risk factors. Methods: Cross-sectional study conducted in 10 health facilities Jazan province. Study participants (2041) were interviewed using a structured questionnaire. HBsAg was tested in the blood samples collected from the study participants using commercially available kits. Results: The overall prevalence of hepatitis B among study participants was 8.3% (95% CI: 7.2 - 9.6). The prevalence of HBsAg was found to be the highest (22.4%) among those who were over 60 years old (95% CI: 13.2 - 35.0). For participants under 20 years old, the prevalence was the lowest, at only 2.5%. For males the HBV prevalence was 11.2% (95% CI: 9.3 - 13.3), compared to 7.0% (95 CI: 5.5% - 8.8%) for females. Subjects with a family history of HBV (p = 0. 002) and dental procedures (p = 0.008) were found to be associated with higher risk for HBV infection. Conclusion: The prevalence of HBsAg in adults in Jazan remains highly relative to KSA national level. Results showed a marked reduction in HBV among participants under 20 years old. This could be mainly attributed to the successful implementation of the children’s HB immunization programs in the region. Additional efforts to control HBV and vaccination for adults are highly recommended.

Journal of Animal and Veterinary Advances , 2012,
Abstract: Sheep and goat pox vaccine strain 0240 was characterized. We designed a pair of primers flanking 3 ORFs including thymidine kinase (tk) gene of Kenya sheep-1. Polymerase chain reaction (PCR) was performed and PCR products of approximately 908 base pair (bp) in size were obtained for all cloned plaques and the vaccine strain. Lamb testicle (LT) DNA (negative control) as expected did not produce any PCR products. PCR products were digested with Ssp1 and Dra1 restriction enzymes and analyzed using agarose gel and polyacrylamide gel electrophoresis (PAGE), respectively. Generation of the expected banding pattern following digestion confirmed virus identity. The analysis revealed the presence of restriction fragment length polymorphisms (RFLPs) between some plaques at temperatures of 33?C and 37?C and the vaccine strain. An in vitro recombination experiment was performed for the 0240 vaccine strain, which revealed its viral sequence heterogeneity. The pattern of heat inactivation indicated the presence of at least two virus populations differing in heat sensitivity. In conclusion, these experiments indicated the presence of two different virus populations.

Open Journal of Radiology (OJRad) , 2016, DOI: 10.4236/ojrad.2016.62017
Abstract: The objective of this study is to assess commonly used formulae (Sheppard, Campbell, Hadlock I, II, III, and IV) for estimation of fetal weight in Sudanese population. A descriptive cross-sectional study was conducted at Saudi Hospital-Khartoum-Sudan; from December 2015 to April 2016. The study included 225 singleton pregnancies. The fetal biometry—Biparietal diameter (BPD), head circumference (HC), abdominal circumference (AC), femur length (FL) and actual birth weights (ABW) were taken. Statistical analysis showed significant results at p ≤ 0.005. Results showed that the significant highest positive correlation between the ABW and the EFW/Kg was seen in the Hadlock I, III and IV equations having an equal values (0.951) followed by Hadlock II (0.946), Sheppard (0.872) and lastly Campbell (-0.925) with significant high degree of negative correlation. The new established equation EFWFLHCAC is the best formula identified in our study to predict Sudanese babies weight ranged between 1.86 Kg to 3.987 Kg.

Open Journal of Radiology (OJRad) , 2016, DOI: 10.4236/ojrad.2016.62020
Abstract: Background: Many centers in Sudan use the reference data for fetal biometry. The recently published population-based reference either overestimated or underestimated the weight of the fetuses. Objective: To establish a national reference for fetal biometry, and weight by gestational age for singleton fetuses in Sudan. Methods: Data were collected on all singleton live births documented in the data collection sheet done at Saudi Hospital from 2015 to 2016 (n = 225). Gestational age estimation was based on the last menstrual period and fetal ultrasound thereafter. Fetal biometry and weight and other 6 fetal weight formulae were assessed. Reference data for fetal growth by gestational age were created. Results: New charts and reference equations are reported in Sudanese population for fetal biparietal diameter, head circumference, abdominal circumference and femur length and fetal weight. Conclusion: We advocate that these reference charts and equations for fetal biometry and weight might be valuable in the clinical use for appropriate ethnic Sudanese.

Eurasian Journal of Medicine , 2012,
Abstract: Objective: In Malaysia, therapeutic drug monitoring (TDM) service started in the late 1980s. Serum concentration measurements depend on commercially available drug assays, which are costly. In the present study, we attempted to document the impact of TDM service on cost and patient outcomes. Materials and Methods: We reviewed the medical records of the patients who were admitted to the hospital over a five-year period, diagnosed with bronchopneumonia and treated with gentamicin. Outcome measures were duration of fever, incidence of nephrotoxicity and length of hospital stay. We calculated the costs of laboratory and clinical investigations, the costs associated with the administration of gentamicin doses, the cost of providing TDM services, the costs associated with medical care by professional staff and the costs of hospital stays during gentamicin treatment. Results: Sixty-six patients were found to meet the inclusion criteria (10 patients were provided with TDM service and 56 patients were not). There was no significant difference in the duration of fever or the length of hospital stay during gentamicin therapy between the two groups. Although serum creatinine levels were not checked in all of the patients after gentamicin therapy, the data analysis did not show any cases of nephrotoxicity. There was no significant difference in the costs of laboratory investigations, the total cost of gentamicin therapy and the costs associated with professional staff between the two groups. The cost of the hospital stay during gentamicin therapy and the total cost of hospitalization were significantly higher in the TDM group. Conclusion: Evaluation in patients with bronchopneumonia shows that TDM in our setting was associated with higher cost; however, we did not observe any significant differences in the clinical outcomes.

Applied Mathematics (AM) , 2012, DOI: 10.4236/am.2012.37107
Abstract: Difference equations or discrete dynamical systems is diverse field whose impact almost every branch of pure and ap- plied mathematics. Every dynamical system an+1=f(an) determines a difference equation and vise versa. We ob-tain in this paper the solution and periodicity of the following difference equation. xn+1=(xnxn-2xn-4)/(xn-1xn-3xn-5, (1) n=0,1,... where the initial conditions x-5,x-4,x-3,x-2,x-1 and x0 are arbitrary real numbers with x-1,x-3 and x-5 not equal to be zero. On the other hand, we will study the local stability of the solutions of Equation (1). Moreover, we give graphically the behavior of some numerical examples for this difference equation with some initial conditions.

Abstract: In this study, a nested Reverse Transcriptase (RT) polymerase chain reaction (RT-PCR)-based assay, for detection of Newcastle Disease Virus (NDV) Ribonucleic acid (RNA) in clinical samples from experimentally infected chicks, was evaluated. The clinical samples used included, blood, tracheal, cloacal, liver, spleen, heart, lung, kidney and brain. The nested RT-PCR was performed in two amplification steps. In the first step, a pair of primers (nd and nd ) was used to amplify a 356 bp specific region in the F gene of NDV. In the second step, a nested pair of primers (nd and nd ) was employed to produce 216 bp amplification products, internal to the annealing sites of primers nd and nd . The 356 bp PCR products were amplified only from lung homogenate, cloacal and tracheal tissues, kidney, heart and brain. However, the 216 bp nested amplification was detected in all tissue samples collected from experimentally infected chicks. The nested amplification confirmed the identity of the first amplified product and increased the sensitivity of RT-PCR assay. RNA samples extracted from Infectious Bursal Disease Virus (IBDV) and Infectious Bronchitis virus (IBV) or total nucleic acid extracted from blood of non infected birds failed to demonstrate the primary or the nested PCR products. The described nested RT-PCR assay provide reliable, rapid, sensitive and specific diagnostic assay for detection of an outbreak of NDV infection among susceptible Birds.
