Project description:In recent years, many studies have reported potential associations between cytokine gene polymorphisms and the development, course, and outcome of sepsis, often with apparently conflicting results. The objective of this study was to investigate single nucleotide polymorphism (SNP) in the interleukin (IL)-1? -31 T/C, IL-6 -174 G/C, tumor necrosis factor ? (TNF-?) -308 G/A, and interferon ? (IFN-?) +874 A/T genes for their possible association with susceptibility to early onset sepsis (EOS) in Saudi newborn infants. A total of 205 newborn infants aged 1-2 days were consecutively enrolled onto the study having met the inclusion criteria (as per the research protocol). DNA was extracted from filter papers using the Chelex-100 method. The cytokines SNP were genotyping using Taqman 5' nuclease allelic discrimination. For cytokine measurements we used the commercially available Enzyme-Linked Immunosorbent Assay (ELISA) kit. Our results show that the circulating IL-1?, IL-6, TNF-?, and IFN-? were significantly (p < 0.001) elevated in EOS patients compared to suspected and sepsis-free control groups; and IL-1? -31C, IL-6 -174G, TNF-? -308G, and IFN-? +874A alleles were associated with EOS in Saudi infants. In conclusion, analysis of cytokines concentrations and SNP for the four tested genes can be used as a predictor of sepsis outcome in newborns.

Project description:IntroductionTo date, there have only been provisional recommendations about the appropriate gestational weight gain in twin pregnancies. This study aimed to contribute evidence to this gap of knowledge.Material and methodsUsing a cohort of 10 603 twin pregnancies delivered between 2000 and 2015 in the state of Hessen, Germany, the individual and combined impact of maternal body mass index and gestational weight gain on maternal and neonatal outcomes was analyzed using uni- and multivariable logistic regression models. The analysis used newly defined population-based quartiles of gestational weight gain in women carrying twin pregnancies (Q1: <419.4 g/week [low weight gain], Q2-Q3: 419.4-692.3 g/week [optimal weight gain], Q4: >692.3 g/week [high weight gain]) and the World Health Organization body mass index classification.ResultsPre-pregnancy body mass index ≥25 kg/m2 was associated with significantly increased rates of cesarean deliveries (aOR1.2, 95% CI: 1.01-1.41) and pregnancy-induced hypertensive disorders (aOR 1.53, 95% CI: 1.11-2.1) but not with any adverse neonatal outcome. Perinatal mortality (aOR 2.23, 95% CI: 1.38-3.6), preterm birth (aOR 1.88, 95% CI: 1.58-2.25), APGAR'5 < 7 (aOR 1.61, 95% CI: 1.19-2.17) and admissions to the neonatal intensive care unit (aOR 1.6, CI: 1.38-1.85) were increased among women with low gestational weight gain. Rates of cesarean deliveries were high in both women with low (aOR 1.25, 95% CI: 1.05-1.48) and high gestational weight gain (aOR 1.17, 95% CI: 1.01-1.35). A high gestational weight gain was also associated with higher rates of hypertensive disorders in pregnancy (aOR 2.32, 95% CI: 1.79-3.02) and postpartum hemorrhage (aOR 1.72, 95%CI: 1.12-2.63). The risk of preterm birth, low Apgar scores and NICU admissions showed a converse linear relation with pre-pregnancy body mass index in women with low gestational weight gain.ConclusionsIn twin pregnancies, nonoptimal weekly maternal weight gain seems to be strongly associated with maternal and neonatal adverse outcomes. Since gestational weight gain is a modifiable risk factor, health care providers have the opportunity to counsel pregnant women with twins and target their care accordingly. Additional research to confirm the validity and generalizability of our findings in different populations is warranted.

Project description:Polycystic ovary syndrome (PCOS) is the most common endocrine disease among premenopausal women. The genetic risk of PCOS in the Saudi population is still unclear. Therefore, it is of interest to study the genotype and allele frequency for six gene variants (THADA rs13429458, TOX3 rs4784165, FSHR rs2268361, YAP1 rs1894116, RAB5B rs705702, and HMGA2 rs2272046) in patients with PCOS in western Saudi population. The study included 95 PCOS patients and 94 normal ovulatory females as controls. Genotyping was performed using TaqMan™ real-time polymerase chain reaction assays. There was significant link between the THADA rs13429458 variant and PCOS. Homozygosity in allele A of the rs13429458 variant was correlated with hyperandrogenism (HA) risk. Homozygosity in the T allele of the FSHR rs2268361 variant was associated with normal levels of AMH among non-PCOS women. The THADA rs13429458 and TOX3 rs4784165 variants were significantly associated with the combined oligo/amenorrhea (OA) and polycystic ovarian morphology subgroups while the HMGA2 rs2272046 variant was significantly associated with the combined HA and OA subgroup. Thus, results show the genetic risk of the THADA rs13429458, TOX3 rs4784165, and HMGA2 rs2272046 variants on PCOS patients in the western Saudi population.

Project description:BackgroundThe practice of hand hygiene (HH) has prime importance among Health Care Professionals (HCPs) and non-compliance could cause adverse consequences. By keeping the importance of HH in mind, this study aims at investigating the knowledge and attitudes towards HH among medical students and interns at King Abdulaziz University (KAU), Jeddah, Saudi Arabia (SA).MethodsThe study includes 453 medical students and interns (189 males & 264 females). This study was completed in three months; from September to November 2017. The World Health Organization (WHO) HH questionnaire was used and data were analyzed on SPSS-21.ResultsTwo-third of the participants 292 (64.2%) had formal training in HH in the last three years. Almost half of the participants 254 (56.1%) had correct knowledge regarding the major course of transmission of potentially detrimental microbes among patients in the healthcare premises. Just 124 (27.4%) of the respondents had the correct knowledge about the most common basis of germs accountable for healthcare-related infections. Females had significantly better knowledge than males regarding the type of HH technique needed before palpation of the abdomen (177(54%) Vs. 151(46%); P < 0.002), before an injection (175(54.5%) Vs. 146(45.5%); P < 0.007), after emptying a bedpan (207(64.7%) Vs. 113(35.3%); P < 0.001), following discarding examination gloves (256(60.4% Vs. 168(39.6%); P < 0.001] and after exposure to blood (200(64.1%) Vs. 112(35.%); P < 0.001). Female participants had better knowledge than males regarding the type of HH actions. Females also had a significantly better attitude towards the importance of HH than males (240(62.5%) Vs. 144(37.5%); P < 0.001).ConclusionThe majority of the participants' knowledge regarding HH was not up to the mark; however, female students had better knowledge compared to male students. The medical students and interns' knowledge and positive attitude towards HH can play a pivotal role in preventing HCPs associated infections and it would overall decrease the infection-related burden on the hospital and governmental budgets. It is suggested that multi-dimensional plans are required to change this low compliance to a higher rate.

Project description:To examine awareness of holistic patient care by staff nurses in the intensive care units of hospitals in the city of Hail, Saudi Arabia. Methods: A quantitative correlational study design was used to investigate relationships between intensive care nurse's awareness of holistic practices and nurses' latest performance review. Intensive care staff nurses (n=99) from 4 public sector hospitals in Hail were surveyed on their awareness of variables across 5 holistic domains: physiological, sociocultural, psychological, developmental, and spiritual. Data were collected between October and December 2015 using written survey, and performance evaluations obtained from the hospital administrations. Results were statistically analyzed and compared (numerical, percentage, Pearson's correlation, Chronbach's alpha). Results: The ICU staff nurses in Hail City were aware of the secular aspects of holistic care, and the majority had very good performance evaluations. There were no demographic trends regarding holistic awareness and nurse performance. Further, awareness of holistic care was not associated with nurse performance. Conclusion: A caring-enhancement workshop and a mentoring program for non-Saudi nurses may increase holistic care awareness and enhance its practice in the ICUs.

Project description:BACKGROUND:The Middle East respiratory syndrome coronavirus (MERS-CoV) is a newly recognized zoonotic coronavirus. Current evidence confirms the role of dromedaries in primary human infections but does not explain the sporadic community cases. However, asymptomatic or subclinical cases could represent a possible source of infection in the community. METHODS:Archived human sera (7461) collected between 2011 and 2016 from healthy adult blood donors from 50 different nationalities in the western part of Saudi Arabia were obtained for MERS-CoV seroprevalence investigation. Samples were tested for MERS-CoV S1-specific antibodies (Abs) by ELISA and confirmed by testing for neutralizing Abs (nAbs) using both pseudotyped and live virus neutralization assays. RESULTS:Out of 7461 samples, 174 sera from individuals with 18 different nationalities were ELISA positive (2.3%, 95% CI 2.0-2.7). Presence of nAbs was confirmed in 17 samples (0.23%, 95% CI 0.1-0.4) of which one sample exhibited positivity in both neutralization assays. Confirmed seropositivity was identified in young (15-44 years) men and women from Saudi Arabia, Egypt, Yemen, Pakistan, Palestine, Sudan, and India without significant preference. CONCLUSIONS:An increasing trend of MERS-CoV seroprevalence was observed in the general population in western Saudi Arabia, suggesting that asymptomatic or mild infections might exist and act as an unrecognized source of infection. Seropositivity of individuals from different nationalities underscores the potential MERS exportation outside of the Arabian Peninsula. Thus, enhanced and continuous surveillance is highly warranted.

Project description:Background:Gomco or Plastibell devices are the most widely used method for circumcision. The present work was aimed to assess the incidence of complications in infants of ages up to six months in two used methods. Methods:It was a prospective randomized study conducted at a pediatric surgery clinic in 3 hospitals in Jeddah, Saudi Arabia. Eight hundred and five children, their ages were less than 6 months were enrolled for the present work. Children were randomized into two groups: Groups P and G using Plastibell and Gomco Circumcision methods, respectively. Statistical analysis of data was performed by using SPSS Version 17. Chi-square test and independent sample t-test was applied to compare both qualitative and quantitative variables, respectively. P-value was considered as significant difference at <0.05. Results:Seven hundred eighty three children were were enrolled in this investigation. Plastibell method was concomitant with low volume of bleeding in comparison with Gomco method (P ?<?0.001). Incidence of complications including infection, penile edema, proximal migration and redundant skin was higher in Plastibell device method (P<0.05). Conclusion:Gomco circumcision is the safer method and is accompanied with lowest rate of complication.

Project description:To determine the prevalence of uncorrected refractive errors (URE) among children 3-10 years and to affirm the necessity of a national school-based visual screening program for school-aged children. Methods: This retrospective cross-sectional study was conducted in Medina, Saudi Arabia in 2015. Children were selected through a multistage stratified random sampling from 8 kindergarten and 8 primary schools. Those included were screened to diagnose UREs using a visual acuity chart and an auto refractometer according to American guidelines. The prevalence and types of UREs were estimated. Results: Of the 2121 children enumerated, 1893 were examined, yielding a response rate of 89.3%. The prevalence of UREs was 34.9% (95% CI = 32.8%-37.1%), with significant differences in different age groups. The prevalence of astigmatism (25.3%) was higher compared to that of anisometropia (7.4%), hypermetropia (1.5%), and myopia (0.7%). Risk of uncorrected refractive error was positively associated with age, and this was noted in astigmatism, myopia, and anisometropia. In addition, the risk of hypermetropia was associated with boys and that of myopia was associated with girls. Conclusions: The prevalence of UREs, particularly astigmatism, was high among children aged 3-10 years in Medina, with significant age differences. Vision screening programs targeting kindergarten and primary schoolchildren are crucial to lessen the risk of preventable visual impairment due to UREs.

Project description:To determine the association of different factors in the mammography related pain perception of women who attended their screening and diagnostic mammography appointments and whether the pain perceived was equal to the pain experienced. Methods: This prospective study was conducted at the Breast Unit of King Abdulaziz University (KAU) Hospital, Jeddah, Kingdom of Saudi Arabia (KSA), in the period between April and May 2015. A structured questionnaire with close-ended questions was given to a sample of 100 women before and after their mammogram, asking about their pain perception and whether it had changed. Results: The factors that affected anticipated mammography pain for the surveyed women were past mammography experiences, previous breast procedures, and the knowledge that was gathered beforehand about mammography. After the mammography, the women who thought the procedure was going to be painful experienced what they expected. The majority of the women who did not expect the mammography to be painful experienced pain during their mammogram. Most of the women who did not know whether it would be painful or not experienced the mammography as painful. Conclusion: Pain expectation can be approached in various ways to make the mammography experience much more tolerable for women, encouraging them to attend and return for their scans.

Project description:A total of 145007 reads were obtained from pyrosequencing for all the 4 samples. The total count ranged from 11,301,014 (Mecca old road) to 23,503,512 bp (Thuwal). A total of 460 fungal species belonging to 133 genera, 58 families, 33 orders, 13 classes and 4 phyla was identified across the four sites. The most abundant phylum at all four sites was Ascomycota followed by Basidiomycota. Four phyla (Ascomycota-99.31%, Basidiomycota-0.59%, Chytridiomycota-0.04%, Glomeromycota-0.03%) were detected in Khulais. Except for Glomeromycota, all phyla were detected at Mecca old road (Ascomycota-74.26%, Basidiomycota-25.71%, Chytridiomycota-0.01%) and Thuwal (Ascomycota-99.59%, Basidiomycota-0.40%, Chytridiomycota-0.002%); while only Ascomycota-90.98% and Basidiomycota-9.01% were detected in Asfan road. At the class level, Sordariomycetes was predominantly observed at Asfan road-59.88%, Khulais-68.26% and Thuwal-94.84%; while Pezizomycetes was dominant at Mecca old road-56.01%, was absent at Asfan road. Agaricomycetes was present only at Mecca old road-25.73%; while Tremellomycetes-5.77%, Malasseizomycetes-2.13% and Microbotryomycetes-1.10% were found only at Asfan road. The phylogenetic trees revealed that clear genus level differences are visible across all the four sites, with an overall predominance of Thielavia followed by Madurella, Aspergillus, and Gelasinospora. Chaetomium sp., Aspergillus caespitosus and Aspergillus sp. were found in moderate (Mecca old road and Thuwal) to abundant (Asfan road and Khulais) quantities. Thielavia sp., Thielavia hyalocarpa and Madurella sp. are found in moderate quantities at Khulais and Mecca old road, while in abundant levels at Asfan road and Thuwal. Fusarium equisati and F. oxysporum were detected at Thuwal and Khulais. Sordaria araneosa was present at Khulais, while Malasseiza globosa species was detected in moderate quantities across all sites except Khulais.
