Evaluation of the knowledge and practices of pregnant Yemeni Women regarding teratogens

Purpose: To investigate the knowledge and practice of pregnant women with regards to teratogens.Methods: A month-long cross-sectional study was carried out among 150 pregnant women selected from four Motherhood and Child Healthcare Centers (MCHCs) in Mukalla District of Yemen. Data collection was conducted during face-to-face interviews using a questionnaire. Descriptive and simple regression analyses were used.Results: Of the 150 pregnant women who participated in the study, 95.3 % of the pregnant women were < 36 years old, 7.4 % had children with congenital malformations, 62 % indicated that they had heard about folic acid; however, only 16.6 % knew the significance of folic acid. Regarding toxoplasmosis, 94.7 % indicated that they had heard about toxoplasmosis, and 76 % knew about the serious consequences of the disease (congenital malformation and abortion) during pregnancy. Based on simple regression analysis, the results indicate that education and parity, irrespective of age or income level, were the major factors determining better knowledge and practices in pregnancy with regards to toxoplasmosis.Conclusion: Knowledge of folic acid deficiency among pregnant women in Mukalla District of Yemen is relatively low. Furthermore, preventive practices to avoid folic acid deficiency are minimal.Keywords: Knowledge, Practices, Teratogens, Pregnant Yemeni women, Folic acid deficienc

EVALUATION OF THE EFFECTIVENESS OF FREE NICOTINE PATCH THERAPY IN A CHARITY CLINIC FOR SMOKING CESSATION

The purpose of this study was to evaluate the efficacy of a free nicotine- patch therapy for smoking cessation in Saudi smokers. A single centered prospective study was carried out in a charity clinic for smoking cessation in Riyadh, Saudi Arabia.  A total of 31 subjects who attended the smoking cessation clinic from June 2014 to August 2014 were studied. All participants were male and their mean age was 31.1±6.4 years. The duration of history of smoking was 12.9±6.8 years. The nicotine- patch therapy outcomes were measured at baseline and at 6 weeks after using nicotine- patch therapy. At base line the number of cigarettes per day was 27±10 and carbon monoxide (CO) level was 20.2±8.3. The analyzed statistics revealed that there were significant decreased in the number of cigarette per day (p=0.001) and Carbon Monoxide (CO) level (p=0.001) over 6 weeks of nicotine- patch therapy. After 6 weeks of therapy, abstinence rate was 58 % (verified by CO level) and no serious adverse reactions were documented. The most common side effects were nausea, headache and local irritation sings. In addition, our finding revealed that smokers were likely to suffer from withdrawal symptoms following trying to quit. These withdrawal symptoms include sleep disturbance, loss of concentration and weight gain as well as irritability. Results of this study show that free nicotine-patch therapy is an effective measure for smoking cessation in Saudi population.Keywords: nicotine patch therapy, smoking cessation clinic, side effect

Self-medication with antibiotics in Saudi Arabia

Introduction: Despite of the global dilemma of antibiotics resistance, this issue is more worsen in developing countries or places where the antibiotics can be dispensed or purchased without prescription such as in Saudi Arabia. Most health awareness campaigns and published studies regarding the self-medication with antibiotics in Saudi Arabia are conducted within hospitals. The prevalence and reasons of self-medication with antibiotics were not well studied from community perspective in Saudi Arabia. This study was conducted to investigate the prevalence of self-medication with antibiotics in Saudi Arabia. Methodology: A cross-sectional study using online survey and snowball technique was conducted during the period from January 2017 to May 2017 targeting people who are living in Saudi Arabia. Results: A total of 1264 respondent completed the questionnaire and included in the study. About 34% of respondents have used antibiotic without a prescription, and 81.3% of them knew that it might be harmful to health. The most antibiotic used for self-medication was Amoxicillin/clavulanic acid (45.1%) followed by amoxicillin (39.9%). The most common illness and reasons for seeking antibiotic without prescription were tonsillitis (76.7%) and the previous experience of using a particular antibiotic (52.1%) respectively. The major source of self-medication with antibiotic was previous doctor's prescription (36.6%). Conclusion: The relative high prevalence of self-medication with antibiotics necessitates taking serious steps by health authorities to implement the law of forbidding the sale of antibiotics without prescription.

Association of Toll-Like Receptor 3 Single-Nucleotide Polymorphisms and Hepatitis C Virus Infection

Toll-like receptor 3 (TLR3) plays a key role in innate immunity by recognizing pathogenic, double-stranded RNAs. Thus, activation of TLR3 is a major factor in antiviral defense and tumor eradication. Although downregulation of TLR3 gene expression has been mainly reported in patients infected with hepatitis C virus (HCV), the influence of TLR3 genotype on the risk of HCV infection, HCV-related cirrhosis, and/or hepatocellular carcinoma (HCC) remains to be determined. Single-nucleotide polymorphisms (SNPs) within the TLR3 gene and their associations with HCV-related disease risk were investigated in a Saudi Arabian population in this study. Eight TLR3 SNPs were analyzed in 563 patients with HCV, which consisted of 437 patients with chronic HCV infections, 88 with HCV-induced liver cirrhosis, and 38 with HCC. A total of 599 healthy control subjects were recruited to the study. Among the eight TLR3 SNPs studied, the rs78726532 SNP was strongly associated with HCV infection when compared to that in healthy control subjects. The rs5743314 was also strongly associated with HCV-related liver disease progression (cirrhosis and HCC). In summary, these results indicate that distinct genetic variants of TLR3 SNPs are associated with HCV infection and HCV-mediated liver disease progression in the Saudi Arabian population

Room and High Temperature Tensile Responses of Tib2-Graphene Al 7075 Hybrid Composite Processed through Squeeze Casting

The development of aluminium composite with the inclusion of advanced materials is a continuous research process due to the increasing industrial demand for advanced hybrid materials. To cater for this need, this research work focuses on the development of Al 7075 alloy reinforced with TiB2 and graphene and on the evaluation of its strengthening mechanism. Two different modes of improving the strength of the hybrid composite have been followed; one is by the inclusion of graphene at three levels of 0.1, 0.2 and 0.3%, and another by the processing route, squeeze casting technique by compression of the molten hybrid composite slurry before casting. The microstructure and characterisation of the composite material are examined and analysed with the help of XRD, SEM, EDAX and chemical spectroscopy. A microstructure evaluation is employed to justify the homogenous dispersal and the existence of reinforced particles. A tensile test is conducted at room temperature and high temperature environments to assess the tensile strength. The research outcome affirms that a significant improvement in tensile and hardness has been noted in comparison with base alloy. The fracture-morphology results affirm the change in fracture mode from brittle to ductile when the tensile testing environment changes from room temperature to high temperature. Finally, the dispersion strengthening mechanism is validated with an empirical approach

Single nucleotide polymorphisms in CXCR1 gene and its association with hepatitis B infected patients in Saudi Arabia

Background/Aim. This study aims to investigate whether the SNPs of CXCR1 gene, could predict the likelihood of viral persistence and/or disease progression.Material and methods. We investigated the association of two different SNPs (rs2234671, and rs142978743) in 598 normal healthy controls and 662 HBV patients from a Saudi ethnic population. The HBV patients were categorized into inactive carriers (n = 428), active carriers (n = 162), cirrhosis (n = 54) and Cirrhosis-HCC (n = 18) sub-groups. Genetic variants in CXCR1 were determined by polymerase chain reaction (PCR)-based DNA direct sequencing.Results. The frequency of the risk allele ‘C’ for the SNP, rs2234671 was found to be insignificant when the patient group was compared to the uninfected control group, however, a significant distribution of the allele ‘C’ of rs2234671 was observed among active HBV carriers + cirrhosis + cirrhosis - HCC vs. inactive HBV carriers with an OR = 1.631 (95% C.I. 1.016-2.616) and p = 0.032. However, no significant association was observed for rs142978743 when the distribution of risk allele was analyzed among the different patient groups (i.e. inactive carriers, active carriers, cirrhosis and HCC). Furthermore, the most common haplotype, Haplo-1 (AG), was found to have an insignificant frequency distribution between HBV cases and controls, while the same haplotype was found to be significantly distributed when active carriers + cirrhosis + cirrhosis - HCC patients were compared to inactive HBV carriers with a frequency of 0.938 and p = 0.0315. Haplo-2 (AC) was also found to be significantly associated with a frequency of 0.058 and p = 0.0163.Conclusion. The CXCR1 polymorphism, rs2234671 was found to be associated with chronic HBV infection and may play a role in disease activity
