    2006-05-01

    The Institute of Astronomy and Geophysics Research at King Abdulaziz City for Science and Technology installed nine earthquake portable stations in central part of Saudi Arabia around Riyadh city to record micro- seismicty that is caused by local faults. Riyadh city and central part of Saudi Arabia are located in the Arabian Plate, which is known as a relatively stable platform. However, we have been able to determine some events that was caused by local faults. Most of these events are not felt. We are using digital recorders (RefTek 72A) for data acquisition and SAISAN software for analyses. The velocity model that I have used in this study is IASPEI model. Currently I am developing a map that shows some micro-earthquake events for that region. In addition, it includes some regional events. The objective of this study is to define the active faults in central part of Saudi Arabia.

    Study Objective The aim of the study was to assess the level of risk for cardiovascular diseases (CVD) among young Saudi women living in Al-Qassim, Saudi Arabia. Methods As part of “The Heart Protection Campaign” in the Al-Qassim region, data were collected from Saudi women using questionnaires as well as objective measurement of height, weight, blood pressure, and blood glucose. Data were analyzed using descriptive statistics. Results Only 15% of the sample were free of risk factors, the majority had either one (57.5%) or two (20.8%) risk factors. Additionally, 6.7% were considered to be at high-risk with three or more risk factors. The most common risk factors were physical inactivity (74%) and overweight/obesity, (25%/29%). There was a significant increase in the number of risk factors across age groups. Women over the age of 30 were more likely to have a higher number of risk factors than the younger women (20–24 years). Conclusions Young women in Al-Qassim, Saudi Arabia have an unusually high risk for CVD. Since the number of risk factors increases substantially between the ages of 20 and 35, there is a need to develop prevention programs to lower the CVD risk through diet and exercise. PMID:27004055

    Alahmad, G H; Dierickx, K

    2014-11-01

    The growth of research biobanks has created many new ethical challenges worldwide. This article outlines and discusses key issues in the governance of Saudi Biobank, a newly established national biobank in Saudi Arabia launched in 2014. The Saudi Biobank project includes human biological samples from participants aged 10-70 years and aims to conduct an extensive study on the influence of genes, environment and lifestyle in common diseases. We examined the strengths and weaknesses of Saudi Biobank's governance as well as the similarities and differences with 4 other biobanks (in the United Kingdom, Iceland, Estonia and Canada). Three different ethical issues are discussed in detail: confidentiality, informed consent and children's participation in research. We evaluated these issues in relation to international ethical guidelines and Islamic law. The insights gained may be useful in developing national biobanking regulations in other Islamic countries, particularly in countries of the Eastern Mediterranean Region. PMID:25601806

    Background and Objective: Vitamin D deficiency is common among Saudi Arabian population. To evaluate the current status of vitamin D fortification and calcium content of commonly consumed food items by the Saudi population and to compare it to US data. Setting and Design: Cross-sectional market survey at markets of Eastern Province of Saudi Arabia and State of Illinois, USA. Methods: A dietary survey was carried out for the content of calcium and vitamin D on the most commonly consumed food products by the Saudi population which are suppose to be fortified by vitamin D. The survey included different brands of fresh milk, yoghurt, powdered milk, cheese, ready-to-eat breakfast cereals and orange juice. Vitamin D content in the products studied from the Saudi marketplace was compared with the suggested vitamin D content in the same products according to US Code of Federal Regulations recommendations. Results: The overall calcium content in the processed dairy products is generally higher than the content in fresh dairy products. Vitamin D content in the fresh dairy products varied from 40 IU/L to 400 IU/L. None of the cereals or orange juice in Saudi Arabia contain vitamin D supplement. The vitamin D content in the food items from the Saudi marketplace is mostly lower than recommended by the US Code of Federal Regulations. Conclusion: Most commonly consumed food products by Saudi population which are suppose to be fortified by vitamin D either not fortified or contain an amount less than recommended by guidelines set for US marketplace.

    Prolonged breastfeeding can prevent or limit the severity of a variety of diseases and conditions. Although evidence clearly shows that there are health benefits for breastfeeding, adherence to breastfeeding remains a key challenge facing maternal health providers in Saudi Arabia. The purpose of this study is to evaluate the impacts of a social media platform (Twitter) to promote breastfeeding in Saudi Arabia. Between February 10 and March 25, 2015, a web-based questionnaire was administered to evaluate the impacts of a Twitter based educational campaign on the awareness, knowledge, and adherence to breastfeeding behavior for women in Saudi Arabia. The overall response rate among mothers with a newborn child was 83% (n=484). The results showed an increase in the knowledge and awareness of breastfeeding practices and adherence among Twitter followers. The initiation rate of breastfeeding had slightly increased among women who never had previously breastfed. More women reported their willingness to continue exclusive breastfeeding and to stop bottle-feeding. Results also show that an integration of professional breastfeeding support, public health education programs through social media could be an effective tool in promoting breastfeeding in Saudi Arabia. There is a need for further research on designing and implementing a social media based educational outreach program to increase women's awareness, knowledge, and adherence to breastfeeding behavior in Saudi Arabia.

    Background: International travel, migration and human population movements facilitate the spread of tuberculosis (TB). Objective: To study the impact of poorly screened expatriates working in Saudi Arabia on the local incidence of TBs. Patients and methods: This cross sectional study was carried out in the Chest Disease Hospital, Taif. All confirmed cases of TB from June 2009 to May 2010 admitted to the hospital were enrolled. Inclusion criteria were diagnosed cases of TB (pulmonary & extra-pulmonary) in patients between the ages of 14 to 65 years. Patients with HIV and coexistent malignancies were excluded. The age, gender and ethnic group of each patient was recorded, and patients were divided into two groups. Of the two groups, Group A consisted of Taif residents and group B of patients referred from other cities in the country. Results: Of the 686 cases studied, 370 (54%) were Saudi nationals (Group A = 80 & Group B = 290) and 316 (46%) cases were from other countries. Males outnumbered females and most of the patients were aged 20 to 29 years. The number of cases from the areas close to the pilgrimage sites, i.e. Makah (233) and Jeddah (275), outnumbered those in Taif (110). Conclusions: Our study identifies an increased prevalence of TB cases in areas close to the pilgrimage (Group B). The higher proportion of non-Saudi TB patients in group B is most likely explained by the higher number of poorly screened illegal expatriates in the region. PMID:24454274

    Background and Aims. Crohn's disease (CD) is an evolving disease in KSA. Little is known about its characteristics in the Saudi population. The aims of this study were to describe the characteristics of Saudi children with CD and to determine whether the characteristics of CD in KSA are different from those seen in Western countries. Methods. In this study, children younger than eighteen years of age diagnosed with CD between January 2003 and December 2012 were included. Results. Of 330 patients identified, 186 (56.4%) were males. The median age at diagnosis was 15.8 years. A positive family history for IBD in first-degree relatives occurred in 13.6% of patients. The most common symptoms were abdominal pain (84.2%), weight loss (75.2%), and diarrhea (71.8%). The main disease location was ileocolonic (42.1%) and the main disease behavior was nonstricturing and nonpenetrating (63.6%). Perianal involvement was seen in 60 (18.2%) patients. Laboratory findings revealed anemia in 57.9% of patients, low albumin in 34.5%, and high CRP in 39.4%. Conclusions. Saudi children with CD have lower frequency of first-degree relatives with IBD, lower prevalence of early onset disease, longer diagnostic delay, higher prevalence of growth failure, and greater frequency of stricturing and penetrating disease behavior compared to Western patients.

    2014-01-01

    Background In this observational study, we aimed to see whether transition in Saudi students entering university life could be a breeding stage for cardiometabolic risk factor emergence and clustering. Methods A total of 1878 apparently healthy Saudi students of the Preparatory Year, King Saud University, Riyadh, KSA (1112 men and 766 women) spanning 2 academic years were included. They were divided into 2 groups based on the validated perceived stress test (PST). Anthropometrics were obtained and fasting blood samples were collected for measurement of fasting blood glucose and a lipid profile. Results PST score (>27) considered indicative of stress was noted in 44.4% of students. The prevalence of this score was higher in women than in men (49.7% versus 40.7%). The prevalence of obesity, hypertension and dyslipidemia was significantly higher in men than women (p < 0.01), and this was even more apparent among stressed men, who had a significantly higher prevalence of all the above cardiometabolic factors than the non-stressed ones (p < 0.01). Conclusion Perceived stress is alarmingly high among Saudi students entering universities. This study sheds light on the social responsibility of universities in promoting a healthy lifestyle, particularly in this age group, when exposure to different kinds of stressors may result in body weight and metabolic changes.

    2016-01-01

    Developing legally compliant systems is a challenging software engineering problem, especially in systems that are governed by law, such as healthcare information systems. This challenge comes from the ambiguities and domain-specific definitions that are found in governmental rules. Therefore, there is a significant business need to automatically analyze privacy texts, extract rules and subsequently enforce them throughout the supply chain. The existing works that analyze health regulations use the U.S. Health Insurance Portability and Accountability Act as a case study. In this article, we applied the Breaux and Antón approach to the text of the Saudi Arabian healthcare privacy regulations; in Saudi Arabia, privacy is among the top dilemmas for public and private healthcare practitioners. As a result, we extracted and analyzed 2 rights, 4 obligations, 22 constraints, and 6 rules. Our analysis can assist requirements engineers, standards organizations, compliance officers and stakeholders by ensuring that their systems conform to Saudi policy. In addition, this article discusses the threats to the study validity and suggests open problems for future research. PMID:25325796

    Introduction Temporary ileostomy is an emergency procedure performed in cases having septic peritonitis in presence of perforation or obstruction or gangrene of small intestine. These patients usually suffer from gross malnutrition following surgery. Aim To measure nutritional status of patients with emergency temporary ileostomy and to determine whether their postoperative nutrition can be favourably maintained by oral diet alone. Materials and Methods Sixty patients were enrolled for the study on the basis of inclusion and exclusion criteria during the study period from January 2012 to December 2013. Oral feeding was started as soon as ileostomy started functioning and patients expressed hunger, about 48-72 hours postoperatively. An individualized diet chart was formulated for each patient using Harris Benedict Equation. Nutritional assessment was done on 1) 1st day of oral feeding, 2) After 7 days of oral feeding, 3). After three months of oral feeding. Nutritional parameters (anthropometric, biochemical) employed were tabulated and statistically analysed with SPSS v 17, Chicago. Results Out of 60 patients, 36 males and 24 females were enrolled in the study. The patients were in the age group of 20-60 years with a mean age of 45 years. After 7 days of oral nutrition the nutritional status deteriorated with a significant decrease in body weight (p<0.001) and serum haemoglobin (p <0.001). However, at the end of the study, the patients had their nutritional status restored satisfactorily with normalization of basic parameters like bodyweight, haemoglobin and serum albumin (p<0.001). Conclusion Proper dietary advice and oral nutrition were found to be sufficient for gradual restoration and maintenance of satisfactory nutritional status in the postoperative period. PMID:26816941

    Background Medication safety is a global concern among healthcare providers. However, the challenges to and the future of medication safety in Saudi Arabia have not been explored. Objectives We explored the perspectives of healthcare practitioners on current issues about medication safety in hospitals and community settings in Saudi Arabia in order to identify challenges to improving it and explore the future of medication safety practice. Methods A total of 65 physicians, pharmacists, academics and nurses attended a one-day meeting in March 2010, designed especially for the purpose of this study. The participants were divided into nine round-table discussion sessions. Three major themes were explored in these sessions, including: major factors contributing to medication safety problems, challenges to improving medication safety practice, and participants’ suggestions for improving medication safety. The round-table discussion sessions were videotaped and transcribed verbatim and analyzed by two independent researchers. Results The round-table discussions revealed that major factors contributing to medication safety problems included unrestricted public access to medications from various hospitals and community pharmacies, communication gaps between healthcare institutions, limited use of important technologies such as computerized provider order entry, and the lack of medication safety programs in hospitals. Challenges to current medication safety practice identified by participants included underreporting of medication errors and adverse drug reactions, multilingualism and differing backgrounds of healthcare professionals, lack of communication between healthcare providers and patients, and high workloads. Suggestions for improving medication safety practices in Saudi Arabia included continuous education for healthcare professionals and competency assessment focusing on medication safety, development of a culture that encourages medication error and adverse

    Background Anaphylaxis is a serious allergic reaction that may cause death. The signs and symptoms of anaphylaxis have not been examined in the Saudi population before. Objective The present study examined the signs, symptoms, triggers, and demographic patterns of patients treated for anaphylaxis at a large tertiary care hospital in Riyadh, Saudi Arabia. Methods All the patients who were prescribed new prescriptions of adrenaline auto-injectors (AAs) between February 1, 2010 and December 31, 2011 were included in this study. Information was collected using a standardized form. Results There were 238 patients who were analyzed. The median age at the time of first AA prescription was 15.5 years. Female to male ratio was 52:48 and 54% of the subjects were more than 18 years of age. There were some differences in the presenting signs and symptoms observed in our study compared with similar studies from around the world. Urticaria and angioedema were the most common at about 70% across all ages, followed by shortness of breath at 28%. Some triggers were found to be more common in our region. Food was the commonest trigger for anaphylaxis including tree nuts, egg, and sesame. Drug allergy was also a common trigger, with penicillins and nonsteroidal anti-inflammatory drugs being the commonest. Regarding insect allergy, samsam ant was the commonest trigger in our study. Conclusion To our knowledge, this is the first study on anaphylaxis in Saudi Arabia. Some of the manifestations of anaphylaxis are significantly different in our population study compared to previously published data from other parts of the world. While managing anaphylaxis, we should be mindful of these differences. This improved understanding should help reduce the morbidity and mortality associated with anaphylaxis in our region.

    During the last decade, the rapid economic development in Saudi Arabia resulted in an unbalanced dietary intake pattern within the general population. Consequently, metabolic syndrome was also documented to be highly prevalent in the Middle-East region. We aimed to examine the relationship between selected dietary nutrient intakes and the prevalence of metabolic syndrome in the general adult population of Riyadh, Saudi Arabia. In this cross-sectional study, 185 adult Saudis aged 19 to 60 years (87 males and 98 females (mean age 35.6 ± 13.2 and 37.6 ± 11.7 years, respectively)) were included. The criteria for metabolic syndrome were based on the International Diabetes Foundation (IDF) criteria, and the dietary food intake was assessed by two 24-h dietary recall methods. The odd ratios (ORs) of metabolic syndrome risk across quartiles of selected dietary nutrients were significantly lower for carbohydrates and proteins, as well as for vitamins A, C, E and K, calcium, zinc and magnesium (p < 0.05 for all) in the female group with metabolic syndrome than those without. The pattern of daily dietary intake of selected nutrients among the general population of Saudi Arabia raises concern, and this dietary imbalance could increase the risk of metabolic syndrome, particularly in adult Saudi females.

    Background COPD is a leading cause of morbidity and mortality worldwide. The prevalence rate of COPD in the general Saudi population is estimated to be 2.4% and 14.2% among smokers. Not much is known about current health care services for patients with COPD in Saudi Arabia. The objective of this study was to determine the current care services for patients with COPD provided by government hospitals in the Eastern province of Saudi Arabia. Methods A cross-sectional study was conducted in the Eastern province of Saudi Arabia. Directors of the Department of Internal Medicine from all 22 general government hospitals that are under the responsibility of the Ministry of Health or the Ministry of Higher Education in this region were asked to participate. Data were collected using a questionnaire. Results The study results indicated that there are limited hospital facilities for patients with COPD: no respiratory departments in any of the included hospitals, no spirometry in 77.3% of the hospitals, no intensive care units in 63.7% of the hospitals, and no pulmonary rehabilitation program in any of the hospitals. Among the included 22 hospitals, 24 respiratory physicians, 29 respiratory therapists, and three physiotherapists were involved in COPD care. Conclusion In conclusion, current care services provided by government hospitals in the Eastern province of Saudi Arabia for patients with COPD do not meet international recommendations for COPD management. Increased awareness, knowledge, and implementation of COPD guidelines by health care providers will most probably improve COPD management in Saudi Arabia. In addition, the government could improve dissemination of information about COPD management through national programs and by offering specific education regarding respiratory diseases.

    Both genetic and non-genetic environmental factors are involved in the etiology of neural tube defects (NTD) which affect 0.5-2/1000 pregnancies worldwide. This study aimed to explore the risk factors for the development of NTD in Saudi population, and highlight identifiable and preventable causes. Similar studies are scarce in similar populations ofthe Arabian Peninsula and North Africa. This is an unmatched concurrent case-control study including NTD cases born at King Khalid University Hospital, Riyadh during a 4-year period (2002-2006). The case-control study included 25 cases and 125 controls (case: control ratio of 1:5). Years of formal education, employment, household environment (including availability of air conditioning) and rate of parental consanguinity did not differ between mothers of cases and controls. Significantly higher proportion of mothers of cases had history of stillbirth compared to control mothers (16% vs 4.1%, P=0.02). Also family history of hydrocephalus and congenital anomalies were more prevalent in cases than controls (P values=0.0000 and 0.003, respectively). There was significant protective effect of periconceptional folic acid consumption both prior to conception (OR 0.02, 95% CI 0.00-0.07) and during the first 6 weeks of conception (OR 0.13, 95% CI 0.04-0.39). Further research, including a larger cohort, is required to enable ascertainment of gene-nutrient and gene environment interactions associated with NTD in Saudi Arabia. PMID:27493405

    Introduction: Many cases of congenital toxoplasmosis can be prevented provided that pregnant women following hygienic measures to avert risk of infection and to reduce severity of the condition if primary prevention failed. Objectives: This descriptive exploratory study aimed to assess the risk behavior and knowledge related to toxoplasmoisis among Saudi pregnant women attending primary health care centers (PHCs) in Al Hassa, Saudi Arabia and to determine socio-demographic characteristics related to risk behavior and knowledge. Methods: All Saudi pregnant women attending antenatal care at randomly selected six urban and four rural PHCs were approached. Those agreed to participate were interviewed using a pre-tested structured questionnaire collecting data regarding socio-demographic, obstetric history, toxoplasmosis risk behaviors and related knowledge. Results: Of the included pregnant women, 234 (26.8%) have fulfilled the criteria for toxoplasmosis preventive behavior recommended by Centers for Disease Prevention and Control to prevent congenital toxoplasmosis, while 48.9% reported at least one risk behavior and 24.3% reported ≥ two risk behaviors. Logistic regression model revealed that pregnant women aged 20 to <30 years and those with previous history of unfavorable pregnancy outcome were more likely to follow toxoplasmosis preventive behavior. Toxoplasmosis-related knowledge showed that many women had identified the role of cats in disease transmission while failed to identify other risk factors including consumption of undercooked meats, unwashed fruits and vegetables, and contacting with soil. Predictors for pregnant women to be knowledgeable towards toxoplasmosis included those aged 30 to <40 years (OR=1.53), with ≥ secondary education (OR=1.96), had previous unfavorable pregnancy outcomes (OR=1.88) and investigated for toxoplasmosis (OR=2.08) as reveled by multivariate regression model. Conclusion: Pregnant women in Al Hasas, Saudi Arabia, are

    Objectives: The objectives of the present study was to explore the readiness for Self Directed Learning (SDL) among first year Saudi Medical students enrolled at King Saud University (KSU) and Princess NourahBintAbdulrahman University (PNU) in Saudi Arabia. Methods: First year medical students were invited to participate in a descriptive cross sectional study design. Data were collected using a Self-Directed Learner Readiness Scale (SDLRS) which is a self- assessment tool aimed to assess three main components: self-management, desire for learning and self-control. The students responded to each item of the SDLRS on a 5-point Likert scale. Data were analyzed using SPSS, mean, median and total scores were calculated and were compared among student’s groups. Results: The mean score for the desire of learning was the highest (4.08± 0.5) of all the three components of the SDLRS followed by self-control (3.9± 0.9), while the least mean score was for self-management (3.7±0.5). Overall, differences between student’s groups were not statistically significant. Conclusion: The present study revealed that the overall SDL readiness of participants was good, students were highly motivated for self-learning and had the ability for self-control. However, they need assistance to improve their self-management skills. PMID:26430406

    This study focuses on the necessary elements to implement strategic mitigation in order to avoid Cuvier's beaked whale (CBW) strandings linked to intense sound sources, such as military active sonars, in the Mediterranean Sea. A careful review of stranding data and the analysis of existing survey results are required to highlight the main characters of the species regional distribution. Focused and repeated surveys are needed to confirm that possible favourable areas, such as the Balearic, Tyrrhenian or Aegean Seas, are really favourable CBW habitats. These surveys should be carried out with sea states 0 to 1 in order to minimize the risk of false absence data. Among the regions of interest, the central Tyrrhenian Sea was surveyed with a 12 m sailboat in 2007 and 2008. With 907 km of effective effort, a mean sighting rate of 1.9 CBW school/100 km was obtained, which is amongst the highest densities recorded in the Mediterranean. PMID:20546808

    Background Autism is a biological disorder with clearly defined phenomenology. Studies from the Middle East on this topic have been particularly rare. Little is known about the influence of culture on clinical features, presentations and management of autism. The current study was done to compare characteristics of autism in two groups of Egyptian as well as Saudi children. Methods The sample included 48 children with Autism Spectrum Disorder. They were recruited from the Okasha Institute of Psychiatry, Ain Shams University, Cairo, Egypt and Al-Amal Complex for Mental Health, Dammam, Kingdom of Saudi Arabia. They were grouped into an Egyptian group (n = 20) and a Saudi group (n = 28). They were assessed both clinically and psychometrically using the GARS, the Vineland adaptive behavioral scale, and the Stanford Binnet IQ test. Results Typical autism was more prevalent than atypical autism in both groups. There were no statistically significant differences in clinical variables like regression, hyperactivity, epilepsy or mental retardation. Delayed language development was significantly higher in the Egyptian group while delay in all developmental milestones was more significant in the Saudi group. The Vineland communication subscale showed more significant severe and profound communication defects in the Saudi group while the Gilliam developmental subscale showed significantly more average scores in the Egyptian group. Both groups differed significantly such that the age of noticing abnormality was younger in the Saudi group. The age at diagnosis and at the commencement of intervention was lower in the Egyptian group. The Saudi group showed a higher percentage of missing examinations, older birth order and significantly higher preference to drug treatment, while the Egyptian group showed a high preference to behavioral and phoniatric therapies, higher paternal and maternal education, higher employment among parents and higher family concern.

    Tuberculosis(TB) is a disease of global significance, which accounts for a death in every 15 seconds. Recent studies shows TB is rising in certain parts of the world, and Saudi Arabia is one of them. Several factor contribute in predisposing the subjects for infection including but not limited to addiction to various compounds which have immune modulation properties, such as amphetamines and Heroin etc. Khat a plant whose leaves are chewed for its euphoric effect in east Africa and Arabian Peninsula including Saudi Arabia, is considered as mildly addictive, and its principle compound, Cathinone shares structural and functional similarity with amphetamine a known immunomodulator. Tuberculosis being a disease of immune modulation has a varied spectrum of complex interplay of proinflammatory molecules, resistin is one of them. In the present study, we try to explore the trinity of khat addiction, serum resistin level and tuberculosis by correlating the serum resistin level in non khat addicted healthy subjects, khat addicted healthy subjects, and in patients, both khat addicted and non khat addicted, with active tuberculosis. We observed significantly higher resistin level among the apparently healthy khat addicted subjects as compared to non addicted healthy controls. Thereafter, when we compare the resistin levels between khat addicted and non khat addicted TB patients we did not found significant difference between the two groups. However bacillary load was observe to be significantly higher among the khat addicted TB patient as compare to non addicted one. Validation of above results in animal model revealed dose dependant increase in bacillary growth in the Wistar rats treated with khat. Taken together these results suggest the role of khat in immune modulation albeit in the limited frame of resistin level. PMID:26448186

    Adverse childhood experiences (ACEs) have been linked with risky health behaviors and the development of chronic diseases in adulthood. This study examined associations between ACEs, chronic diseases, and risky behaviors in adults living in Riyadh, Saudi Arabia in 2012 using the ACE International Questionnaire (ACE-IQ). A cross-sectional design was used, and adults who were at least 18 years of age were eligible to participate. ACEs event scores were measured for neglect, household dysfunction, abuse (physical, sexual, and emotional), and peer and community violence. The ACE-IQ was supplemented with questions on risky health behaviors, chronic diseases, and mood. A total of 931 subjects completed the questionnaire (a completion rate of 88%); 57% of the sample was female, 90% was younger than 45 years, 86% had at least a college education, 80% were Saudi nationals, and 58% were married. One-third of the participants (32%) had been exposed to 4 or more ACEs, and 10%, 17%, and 23% had been exposed to 3, 2, or 1 ACEs respectively. Only 18% did not have an ACE. The prevalence of risky health behaviors ranged between 4% and 22%. The prevalence of self-reported chronic diseases ranged between 6% and 17%. Being exposed to 4 or more ACEs increased the risk of having chronic diseases by 2-11 fold, and increased risky health behaviors by 8-21 fold. The findings of this study will contribute to the planning and development of programs to prevent child maltreatment and to alleviate the burden of chronic diseases in adults. PMID:24974249

    Previous reports found that identification of diabetic patients at high risk of foot ulcers, and managing the risk factors early, lower extremity amputations could be prevented. The aim of this study is to determine the value of screening diabetics in estimating the risk of foot ulceration among surgical inpatients. This is a prospective study on all diabetic patients admitted to the surgical department, King Fahd Hospital of the University, Saudi Arabia, during the year 2011. Patients were screened for the presence of diabetic foot. They were classified according to the international working group on the diabetic foot into four grades [0 (lowest risk patients), 1, 2, 3 (highest risk patients)]. During the study period, 391 patients had diabetes mellitus (DM), of these 73 (19%) had active ulcer and were excluded from the study and the rest were screened. Grade 0 was in 174 (54.5%) patients, the rest were grades 1, 2, and 3. There was significant difference between low-risk groups (grades 0, 1) and high-risk groups (grades 2, 3) as regards age, smoking and duration of DM. This study indicates that prevalence of diabetic patients with risk of foot ulceration in surgical inpatients was high. Routine screening of diabetic foot is recommended specially in old patients.

    It has been hypothesized that chronic renal failure (CRF) predisposes patients to infection with intestinal protozoa. We tested this hypothesis with a matched case-control study to determine the prevalence of these protozoa and their diarrhea associated symptoms among 50 patients with CRF (cases) from Taif, western Saudi Arabia. Fifty diarrheal patients without CRF were recruited in the study as controls. Participants were interviewed by a structured questionnaire and stool samples were collected. Samples were thoroughly examined with microscopy and three coproantigens detection kits. Enteric protozoa were detected in 21 cases and 14 controls. Blastocystis spp. were the most predominant parasite (16% in cases versus 8% in controls), followed by Giardia duodenalis (10% in cases versus 12% in controls) and Cryptosporidium spp. (10% in cases versus 6% in controls). Cyclospora cayetanensis was identified in two cases, while Entamoeba histolytica was described in one case and one control. Intestinal parasitism was positively associated with the male gender, urban residence, and travel history. Clinical symptoms of nausea/vomiting and abdominal pain were significantly varied between the parasitized cases and controls (P value ≤ 0.05). Given the results, we recommend screening all diarrheal feces for intestinal protozoa in the study's population, particularly those with CRF. PMID:26491455

    Background and Purpose. Eosinophilic esophagitis (EE) is an evolving allergic disease with an accelerated incidence. The purpose of this study was to delineate the relative frequency and clinicopathological characteristics of EE in children from western Saudi Arabia. Methods. Children with EE were studied retrospectively between October 2002 and December 2011 at King Abdulaziz University Hospital and International Medical Center. Results. The relative frequency of EE was 0.85% of 2127 upper gastrointestinal endoscopies performed during the study period. Eighteen patients were identified with EE. The median age was 8.6 years (range, 1.5–18 years). Thirteen (72.2%) were males. Dysphagia and vomiting were the most common symptoms. Ten (55.6%) children had history of atopy. Testing for food allergy by skin prick test was positive in 11 (61.1%). The most common endoscopic abnormalities were mucosal longitudinal furrow and loss of vascular pattern followed by patchy specks and strictures. The histopathological findings included increased intraepithelial eosinophils, eosinophilic degranulation, lamina propria fibrosis, and eosinophilic microabscesses. Treatment was initiated by swallowed topical corticosteroids in 12 (66.7%) and oral prednisolone in 6 (33%) patients, followed by low dose of topical corticosteroids and dietary elimination. Conclusions. Eosinophilic esophagitis is an uncommon but evolving problem. A high index of suspicion is required for early identifications and intervention to avoid possible complications.

    Lip-print groove patterns have recently been verified as a unique parameter for identification. This study investigated the stability of lip-print patterns over time to validate their secure use in civil and criminal investigations. One hundred and sixteen female lip prints were analyzed and compared with the prints of the same subjects taken 3 years earlier. The old and new lower lip prints of each subject were examined for similarities in the groove patterns in different areas of the lip (lower right, lower middle and lower left), and a score for similarity was developed for the statistical analysis of the lower lip stability data. No significant difference in the frequency of pattern types was detected between old and new prints (P > 0.05). Statistically, 89.6% of subjects showed characteristic typical groove(s) in the lip area(s) of the old and corresponding new prints: 24.1% in the three areas, 48.3% in two areas and 17.2% in one area. This study proves the lasting stability of lip-print patterns over the years in Saudi females and recommends paying attention to the presence of characteristic typical grooves in these prints. Further studies on larger samples, including male prints, should be performed to validate the lip prints for criminal use. PMID:24485442

    This study examined the role of women's work as a possible determinant (among others) of low birth weight in the population of women followed in a Primary Health Care (PHC) center in Abha, Southern Saudi Arabia. All antenatal care files for all deliveries in the preceding 5 years were studied and the relevant data from 7067 files were collected and analyzed. Low birth weight was significantly higher in working mothers (odds ratio=1.31), adolescent mothers (odds ratio= 2.56), and low parity mothers (OR= 1.28). Anemia of the mother contributed an odds ratio of 1.23 for low birth weight baby and inadequate antenatal care (less than 3 visits during pregnancy) had an odds ratio of 1.9. Female babies were significantly more prone to low birth weight (odds ratio 1.34). It is suggested that further evaluation of women's work conditions to detect and remedy stressful conditions especially during pregnancies, health education and better antenatal care may prevent a good proportion of low birth weight deliveries.

Under the impact of rapid economic growth, urbanization has advanced rapidly and 95% of the population is now settled. Saudi Arabia, a monarchy, is divided into 14 provinces that are governed by princes or relatives of the royal family. Oil is the major source of foreign exchange, contributing 81% of government revenues. Ample government funds and foreign exchange resources are available for development, defense, and aid to other Arab and Islamic countries. The government has sought to allocate its petroleum income to transform its relatively undeveloped oil-based economy into that of a modern industrial state while maintaining traditional Islamic values. The standard of living of most Saudis has improved significantly. A shortage of skilled workers at all levels remains the principal obstacle to rapid development. PMID:12178138

  19. Why Would Khat Chewers Quit? An In-Depth, Qualitative Study on Saudi Khat Quitters

    2013-01-01

    Background: Khat chewing, which has many adverse health and social consequences, is highly prevalent and socially accepted in the Jazan region of the Kingdom of Saudi Arabia. Methods: A qualitative study was conducted with 47 adult male former khat users regarding their khat initiation, continuance, and cessation, the amounts of khat they had used, and the health and social consequences of their use and cessation of use. Results: Participants noted a desire to show maturity, ease of availability of khat, and peer pressure as reasons for initiating khat chewing. Many noted long leisure times with little to do as a reason for continuing use. Negative consequences of khat use were seen in economic, health, familial, and sexual areas of their lives. After quitting khat use, participants saw improvements in all of these areas. Conclusions: A comprehensive community development program (CCDP) tackling, among other issues, the normalization of khat use, substantial leisure times with few positive activities, and misinformation about the “benefits” of khat use, as well as developing peer and family training programs to help prevent or stop khat use, would be useful to reduce khat chewing in this community.

    The present study provided information on the susceptibility status of the adult and larvae of Aedes aegypti mosquitoes in Jazan region of Saudi Arabia. Bioassay tests were performed on adults and larvae by using WHO recommended concentrations and test kits. Adults of Ae. aegypti mosquitoes were exposed to test papers impregnated with Lambda-cyhalothrin (0.05%), Cyfluthrin (0.15%), Deltamethrin (0.05%), Permethrin (0.75%), Fenitrothion (1%), Bendiocarb (0.1%) and DDT (4%) insecticides. Ae. aegypti mosquitoes were found to be susceptible only to Cyfluthrin; (mortality rate was 100%), whereas variable resistances were observed from the rest of the other insecticides tested (mortality rates ranged between 93.6 and 17%). Larvae were subjected to different concentrations of Diflubenzuron, Methoprene (IGRs) and Temephos (Organophosphate). Adult emergence inhibition (IE₅₀ & IE₉₅) values for the IGRs and the (LC₅₀ & LC₉₅) for Temephos were determined by log-probit regression analysis. Ae. aegypti larvae were resistant to Temephos (LC₅₀ 61.8-LC₉₅ 35600.1 mg/l) and showed high susceptibility to Methoprene than Diflubenzuron (IE₅₀ 0.49-IE₉₅ 10.9 mg/l) and (IE₅₀ 0.86 and IE₉₅ 93.8 mg/l), respectively. Larvae were more susceptible to Methoprene than Diflubenzuron by 1.8 folds. PMID:27363057

    This study aimed to explore Saudi Arabian women's perceptions of how gendered social structures affect their health by understanding their perceptions of these influences on their health relative to those on men's health. Qualitative methods, including focus group discussions (FGDs) and in-depth individual interviews (IDIs) were conducted with 66 married women in Riyadh, the capital city. Participants were purposively sampled for maximum variation, including consideration of socio-economic status, age, educational level, health status and the use of healthcare. The majority of women perceived their health to be worse than men's and attributed this to their childbearing, domestic and care-giving roles, restrictions on their mobility, poverty and psychological stress related to their responsibilities for children, and marital conflict. A minority of participants felt that men's health was worse than women's and related this to their gendered roles as "breadwinners," greater mobility and masculine norms and identities. Gender equity should be a health policy priority to improve women's health. PMID:24093453

    The binding interactions of two neonicotinoids, imidacloprid (IMI) and thiacloprid (THI) with the extracellular domains of cockroach and honeybee α6 nicotinic acetylcholine receptor (nAChR) subunits in an homomeric receptor have been studied through docking and molecular dynamics (MD) simulations. The binding mode predicted for the two neonicotinoids is validated through the good agreement observed between the theoretical results with the crystal structures of the corresponding complexes with Ac-AChBP, the recognized structural surrogate for insects nAChR extracellular ligand binding domain. The binding site of the two insect α6 receptors differs by only one residue of loop D, a serine residue (Ser83) in cockroach being replaced by a lysine residue (Lys108) in honeybee. The docking results show very close interactions for the two neonicotinoids with both α6 nAChR models, in correspondence to the trends observed in the experimental neonicotinoid-Ac-AChBP complexes. However, the docking parameters (scores and energies) are not significantly different between the two insect α6 nAChRs to draw clear conclusions. The MD results bring distinct trends. The analysis of the average interaction energies in the two insects α6 nAChRs shows indeed better affinity of neonicotinoids bound to α6 cockroach compared to honeybee nAChR. This preference is explained by tighter contacts with aromatic residues (Trp and Tyr) of the binding pocket. Interestingly, the non-conserved residue Lys108 of loop D of α6 honeybee nAChR interacts through van der Waals contacts with neonicotinoids, which appear more favourable than the direct or water mediated hydrogen-bond interaction between the OH group of Ser83 of α6 cockroach nAChR and the electronegative terminal group of the two neonicotinoids (nitro in IMI and cyano in THI). Finally, in both insects nAChRs, THI is consistently found to bind more favourably than IMI. PMID:25424654

    A shallow and short-lived subsynoptic cyclone is discussed as one of typical events causing natural disasters over Saudi Arabia on 5 January 2002 using the Japan Meteorological Agency global analysis dataset. The main cause for its formation was vorticity stretching. On the same day widespread rainfall over Saudi Arabia with enhanced precipitation over the mountainous Jeddah region was also observed using the Global Precipitation Climatology Project dataset. Owing to eastward-moving wintertime synoptic-scale Mediterranean disturbances, this rainfall was associated with frontal activity, modified by the local orography.

    The aim of this research is to investigate groundwater depth in desert and dry environmental conditions area . The study site located in Wadi Nisah-eastern part of Najd province (east-central of Saudi Arabia), Generally, the study site is underlain by Phanerozoic sedimentary rocks of the western edge of the Arabian platform, which rests on Proterozoic basement at depths ranged between 5-8km. Another key objective of this research is to assess the water-table and identify the bearing layers structures study area by using Vertical Electrical Sounding (VES) 1D imaging technique. We have been implemented and acquired a sections of 315 meter vertical electrical soundings using Schlumberger field arrangements . These dataset were conducted along 9 profiles. The resistivity Schlumberger sounding was carried with half-spacing in the range 500 . The VES survey intend to cover several locations where existing wells information may be used for correlations. also location along the valley using the device Syscal R2 The results of this study concluded that there are at least three sedimentary layers to a depth of 130 meter. First layer, extending from the surface to a depth of about 3 meter characterized by dry sandy layer and high resistivity value. The second layer, underlain the first layer to a depth of 70 meter. This layer has less resistant compare to the first layer. Last layer, has low resistivity values of 20 ohm .m to a depth of 130 meter blow ground surface. We have observed a complex pattern of groundwater depth (ranging from 80 meter to 120 meter) which may reflect the lateral heterogeneity of study site. The outcomes of this research has been used to locate the suitable drilling locations.

    Epidemiological and molecular data on community acquired methicillin resistant Staphylococcus aureus (CA-MRSA) are still scarce in both Egypt and Saudi Arabia. There is almost no data regarding methicillin resistant Staphylococcus aureus (MRSA) prevalence in both countries. This study was conducted to investigate the prevalence and molecular epidemiology of S. aureus and MRSA nasal carriage among outpatients attending primary health care centers in two big cities in both countries. A total of 206 nasal swabs were obtained, 103 swabs from each country. S. aureus isolates were characterized by antibiotic susceptibility, presence of mecA and PVL genes, SCCmec-typing and spa typing, the corresponding Multi locus sequence typing clonal complex was assigned for each spa type based on Ridom StaphType database. MRSA was detected in 32% of the Egyptian outpatients while it was found in 25% of the Saudi Arabian outpatients. All MRSA isolates belonged to SCCmec type V and IVa, where some isolates in Saudi Arabia remained nontypeable. Surprisingly PVL(+) isolates were low in frequency: 15% of MRSA Egyptian isolates and 12% of MRSA isolates in Saudi Arabia. Two novel spa types were detected t11839 in Egypt, and t11841 in Saudi Arabia. We found 8 spa types among 20 isolates from Egypt, and 12 spa types out of 15 isolates from Saudi Arabia. Only two spa types t008 and t223 coexisted in both countries. Four clonal complexes (CC5, CC8, CC22, and CC80) were identified in both Egypt and Saudi Arabia. However, the data collected lacked a representation of isolates from different parts of each country as only one health center from each country was included, it still partially illustrates the CA-MRSA situation in both countries. In conclusion a set of control measures is required to prevent further increase in MRSA prevalence. PMID:25523075

    We report our experience of stroke in 136 young adults aged from 18 to 45 years seen in the Eastern Province of Saudi Arabia over a 10-year period. They constituted 25% of all our stroke cases. Thirty-eight percent were Saudi nationals and 62% expatriates. Males largely outnumbered females. The frequency of cerebral infarction (54%) was not very different from that of intracranial hemorrhage (45%). Atherosclerosis and embolism of cardiac origin were the major causes of infarction. The main causes of intracranial bleeding were arterial aneurysms, arteriovenous malformations and hypertension. However, the causes of 29% of ischemic strokes and 44% of hemorrhagic ones remained undetermined. Interethnic comparison of the causes showed that hemorrhages were significantly more frequent in Far East immigrants. Sixty five percent of cerebral infarctions in Asiatic patients remained of undetermined origin. The local variant of sickle cell gene did not seem to play a major role in the pathogenesis of stroke in the Saudi young adult. These data are commented and compared with similar reported data. The influence of the demographic structures of the Saudi population and immigrants communities is analyzed. PMID:1494727

    Background and Objective: Total knee arthroplasty (TKA) is commonly performed in Saudi Arabia but there is very limited published data on outcome and quality of life (QOL) post Knee arthroplasty. To assess the QOL post TKA we performed this retrospective study. Methods: Total Knee arthroplasty was started in mid- 2000’s at the university hospital. Fifty–two patients of TKA who came for follow up during the study period were asked to fill a pre-determined questionnaire and clinical examination, were included in the study. Patients were assessed and at 2 parameters pre and postoperative time-points, for pain [1-9], walking [1-9] and asked whether they would recommend the procedure to their relatives and friends, and finally whether they were satisfied with the outcome. Results: We interviewed 52 patients (9 males and 43 females), mean age of 64.75 ± 7.90 years. Twenty (34.50%) had bilateral TKR, and the rest single sided. The preoperative night pain was 7.72 ± 2.03 compared to postoperative 1.92 ± 1.41 (P<0.001 (5.80 and < 6.47) and pain at walking was 8.39 ± 0.77 versus 2.39 ± 2.05 (P<0.001(5.40 and < 6.55). The overall satisfaction 93% (8.37 ± 1.32) and QOL as assessed preoperatively was 3.60 ± 2.15 and postoperatively was 8.41  ±  1.27 (P<0.001 (4.81and 4.13). Fifty-one (98.07%) patients indicated that they will recommend the procedure to others. Conclusions: The overall satisfaction and improvement of QOL in male patients was 93.77% and female patients 92.77% and all patients indicated that they will recommend others to undergo the similar procedure to improve their QOL.

    The dramatic asymmetry in terms of surface elevation, Cenozoic volcanisms, and earthquake activity across the Red Sea is an enigmatic issue in global tectonics, partially due to the unavailability of broadband seismic data on the African plate adjacent to the Red Sea. Here we report the first results from a receiver function study of the mantle transition zone (MTZ) discontinuities using data from the Egyptian National Seismic Network, and compare the resulting depths of the 410 and 660 km discontinuities (d410 and d660) with those observed on the Arabian side. Results using more than 6000 P-to-S receiver functions recorded at 49 broadband seismic stations in Egypt, Saudi Arabia and adjacent areas show that when the IASP91 Earth model is used for time-to-depth conversion, the resulting depth of the discontinuities increases systematically toward the axis of the Afro-Arabian Dome (AAD) from both the west and east. Relative to the westernmost area, the maximum depression of the 410-km discontinuity is about 30 km, and that of the 660-km discontinuity is about 45 km. Highly correlated d410 and d660 depths suggest that the observed apparent depth variations are mostly caused by lateral velocity anomalies in the upper mantle, while the 15 km additional depression of the d660 relative to the d410 requires either a colder-than-normal MTZ or the presence of water in the MTZ. We tested several models involving upper mantle and MTZ velocity anomalies and undulations of the MTZ discontinuities due to temperature anomalies and water content, and found that the observed systematic variations can best be explained by a model involving a hydrated MTZ and an upper-mantle low-velocity zone beneath the AAD (Mohamed et al., 2014, doi: 10.1093/gji/ggu284). Models invoking one or more mantle plumes originated from the MTZ or the lower-mantle beneath the study area are not consistent with the observations.

    Background: Job satisfaction is a major determinant of job performance, manpower retention and employee well-being. Objectives: To explore the state of job satisfaction among the academic staff of King Faisal University – Dammam (KFU-D), and detect the areas and groups at a higher risk of being dissatisfied. Method: A fully-structured 5-option Likert-type Job Satisfaction Questionnaire (JSQ) composed of an evaluative item and eleven domains making a total of 46 items was used. It was distributed by internal mail to all the 340 academic staff, 248 of whom returned completed questionnaires (response rate = 72.9 %). Findings: The overall mean Job Satisfaction Rate (JSR) was 73.6 %. The highest JSR's were found in three domains (“Supervision”, “Responsibility”, and “Interpersonal Relationships”), and the lowest in four others (“Salary”, “My Work Itself”, “Working Conditions”, and “Advancement”). The JSR was significantly lower among Saudi nationals, females, those below age 40, those from clinical medical and Dentistry departments. Multiple Regression identified six independent variables which conjointly explained 25 % of the variance in job satisfaction (p < 0.0001). These were: being an expatriate, above the age of 50, serving the university for less than one or more than ten years, and, not from a clinical department of Medicine or Dentistry. Conclusions Most staff were satisfied with many aspects of their jobs, but there was significant dissatisfaction with several job-related aspects and demographic features. Appropriate interventions are indicated. Further studies are needed to confirm the present findings and to monitor future trends. PMID:23012199

    Background Antibiotics sales without medical prescriptions are increasingly recognized as sources of antimicrobial misuse that can exacerbate the global burden of antibiotic resistance. We aimed to determine the percentage of pharmacies who sell antibiotics without medical prescriptions, examining the potential associated risks of such practice in Riyadh, Saudi Arabia, by simulation of different clinical scenarios. Methods A cross sectional study of a quasi-random sample of pharmacies stratified by the five regions of Riyadh. Each pharmacy was visited once by two investigators who simulated having a relative with a specific clinical illness (sore throat, acute bronchitis, otitis media, acute sinusitis, diarrhea, and urinary tract infection (UTI) in childbearing aged women). Results A total of 327 pharmacies were visited. Antibiotics were dispensed without a medical prescription in 244 (77.6%) of 327, of which 231 (95%) were dispensed without a patient request. Simulated cases of sore throat and diarrhea resulted in an antibiotic being dispensed in (90%) of encounters, followed by UTI (75%), acute bronchitis (73%), otitis media (51%) and acute sinusitis (40%). Metronidazole (89%) and ciprofloxacin (86%) were commonly given for diarrhea and UTI, respectively, whereas amoxicillin/clavulanate was dispensed (51%) for the other simulated cases. None of the pharmacists asked about antibiotic allergy history or provided information about drug interactions. Only 23% asked about pregnancy status when dispensing antibiotics for UTI-simulated cases. Conclusions We observed that an antibiotic could be obtained in Riyadh without a medical prescription or an evidence-based indication with associated potential clinical risks. Strict enforcement and adherence to existing regulations are warranted. PMID:21736711

    2015-01-01

    Background: In Saudi Arabia there is an estimated need of more than 100,000 pharmacy graduates to cover all present sectors. The shortage of pharmacists has affected many of these sectors especially the pharmaceutical industry. The contribution of Saudi pharmacists to local pharmaceuticals industry would be extremely beneficial and important for shaping the future of the drug industry within the Kingdom. It is not clear whether future Saudi pharmacists are willing to contribute to local pharmaco-industrial fields. Methods: A cross-sectional, questionnaire-based survey was conducted on all final-year pharmacy students in King Saud University (KSU), Riyadh, Kingdom of Saudi Arabia (KSA). Results: Out of a total of 130 students registered in the final-year of the pharmacy program in KSU, 122 (93.8%) were able to complete the questionnaire. The results showed that the majority (83%) of Saudi pharmacy students indicated that they had not received practical training in the pharmaceutical companies, while only 17.2% of the students felt that they had the knowledge and the skills to work in the pharmaceutical industry after graduation. The majority of the students (66.7%) chose clinical pharmacy as their future career field while only 10.9% indicated willingness to work in a pharmaceutical industry career. Only 8.2% selected working in the pharmaceutical industry. The significant predictor of possibly choosing a career in the local drug industry is a student with a bachelor’s degree (compared to Pharm D degree) in pharmacy (OR = 2.7 [95% CI 1.1–6.3]). Conclusion: Pharmacy students who are enrolled in the capital city of Riyadh are not properly trained to play an influential role in local drug companies. As a result, their level of willingness to have a career in such important business is not promising (more among Pharm D program). Future research in other pharmacy colleges within Saudi Arabia is needed to confirm such results. PMID:26594125

    Orbital cellulitis is an infrequent complication of acute ethmoiditis possibly leading to life- or visual-threatening complications. Despite its natural history is well known, its clinical evolution may widely vary among patients, and even in the most favourable cases long-term sequelae may persist. We here provide a step-by-step iconographic description of a periorbital and orbital cellulitis occurring in a child with ipsilateral acute rhinosinusitis. Our report shows that an unusual long-term evolution of periorbital and orbital cellulitis is possible also in apparently favourable cases. PMID:24594215

    Sera from 2,630 apparently normal adult camels (Camelus dromedarius) raised in central Saudi Arabia (Riyadh and Al-Kharj cities) were examined serologically by the Rose Bengal and standard United States of America Brucella plate agglutination tests. The overall seroprevalence of brucellosis in the restricted populations of tested camels was 8%. The seroprevalence of brucellosis among camels raised in small numbers in the backyards of 24 houses in Riyadh and those intensively raised on one large camel farm near Al-Kharj were 4.3% and 8.6% respectively. Fresh milk samples from 100 brucellosis seropositive camels from Riyadh and Al-Kharj were cultured on Brucella-selective media. Brucella melitensis biovars 1 and 2 were isolated and identified from 26 camels. Epidemiologically, brucellosis in camels in central Saudi Arabia appeared to be connected with B. melitensis infection of sheep and goats, and also represents a serious public health risk.

    To highlight the prevalence and future projections of type 2 diabetes mellitus in the Kingdom of Saudi Arabia. The systematic analytic study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia, from Dec 2014 to April 2015. Systematic bibliographic search of scientific databases including ISI-web of science, PubMed and Google Scholar was conducted with key words of "diabetes mellitus" "prevalence", "incidence". Total 46 peer reviewed papers were selected and examined. All the experimental and epidemiologic studies reporting the prevalence of diabetes in Saudi Arabia were included. There was no restriction on publication prestige and language of the publication. Finally, we included 21 publications and remaining 25 papers were excluded. The future predicted prevalence of type 2 diabetes was calculated on the results of the published studies by regressing the 33 years (1982-2015) of prevalence rate of diabetes against the time period. The prevalence of type 2 diabetes in Saudi Arabia is 32.8%. However, the predicted prevalence will be 35.37% in 2020; 40.37% in 2025 and 45.36% in the year 2030. The coefficient on time factor indicated that prevalence rate has increased during 1982-2015. Saudi Arabia has a highest prevalence (32.8%) of type 2 diabetes mellitus. We forecast that the incidence of type 2 diabetes will increase from 32.8% in 2015 to 45.36% in 2030. Saudi Arabia should include diabetes preventive measures on a war footing basis in their national health policy to minimize the burden of the disease. PMID:27339576

    Obesity has become a global epidemic. It’s level in the Middle Eastern and Asian countries have reached to an alarming level. Rapid transition of life style and urbanization has not only affected adults but also the younger population. Objective This study records the trends of prevalence of obesity and over weight in the school children of both genders of Al Qassim region by employing three different non-invasive methods and recorded their differences. Subjects and methods This cross-sectional study was conducted on Saudi students of secondary and intermediate levels between 12–14 years of age. The total number of the students who participated in the study was 242, 129 males and 113 females. A self-administered pre-coded questionnaire was used. Body mass index, skin fold thickness and bioelectrical impedance analyzer (BIA) readings were recorded. Data was analyzed on SPSS version 11. Descriptive statistical analysis was performed. Chi square test with a P value <0.05, was used to compare the prevalence rates. Results Prevalence of obesity and over-weight recorded were higher in the boys but the rates recorded by three methods have shown a wide variation. Several factors, such as change in dietary habits, socioeconomic status and the family history of obesity have shown association but physical inactivity and father’s obesity were found significant contributory factors. There is an urgent need for intervention to prevent and control obesity and its consequences amongst children in Saudi Arabia. PMID:27610061

    Background/Aim: Linear growth impairment (LGI) is one of the most important features peculiar to children with inflammatory bowel disease (IBD). The aim of this report is to define the impact of IBD on the linear growth of children in the Kingdom of Saudi Arabia (KSA). Setting and Design: Multicenter retrospective study. Patients and Methods: Data from a cohort of newly- diagnosed children with IBD from 2003 to 2012 were analyzed retrospectively. The diagnosis of IBD was confirmed in accordance with the published criteria. Length/height for age was measured at diagnosis. The World Health Organization (WHO) reference was used and LGI was defined by length/height for age <-2 standard deviation. Results: There were 374 children from 0.33 to 16 years of age, including 119 ulcerative colitis (UC) (32%), and 255 Crohn's disease (CD) (68%) patients. The prevalence of LGI was 26%, 28%, and 21% in IBD, CD, and UC, respectively. In children below 10 years, LGI was significantly more common in CD (P = 0.010), while in UC children, it was more common in older children (P = 0.011). Conclusion: This study demonstrates a prevalence of LGI consistent with that reported in the literature, but higher in CD children with early onset (<10 years) and in older children with UC, underscoring the importance of monitoring growth in children with IBD in the Saudi population. Prospective studies are needed to define the impact of IBD on growth velocity, puberty, and final adult stature. PMID:26997215

    The paper discussed an exploratory study of government employees’ perceptions of the introduction of biometric authentication at the workplace in the Kingdom of Saudi Arabia. We suggest that studying the factors affecting employees’ acceptance of new technology will help ease the adoption of biometric technology in other e-government applications. A combination of survey and interviews was used to collect the required data. Interviews were conducted with managers and questionnaires were given to employees from two different government organisations in the Kingdom of Saudi Arabia to investigate the employees’ perceptions of using biometrics. The results of this study indicate a significant digital and cultural gap between the technological awareness of employees and the preferred authentication solutions promoted by management. A lack of trust in technology, its potential for misuse and management motives reflect the managers’ need to consider their responsibilities for narrowing these gaps. It was apparent that overcoming employees’ resistance is an essential issue facing biometric implementation. Based on the research we recommend that an awareness and orientation process about biometrics should take place before the technology is introduced into the organisation.

    Background: The high prevalence of physical inactivity in Saudi Arabia is a growing challenge to public health. This study aimed to examine the prevalence of physical activity (PA) and associated factors among female university students. Methods: This cross-sectional study involved 663 randomly selected female university students who completed the Arab Teens Life Style questionnaire. Data included measurements of anthropometric, socioeconomic and environmental factors, as well as self-reported PA. Ordinal regression was used to identify associated factors with low, moderate and high PA levels. Results: The mean age of participants was 20.4 years (SD 1.5). Mean BMI of the students in relation to PA were 23.0, 22.9, 22.1 for high, moderate and low levels of activity, respectively. The analysis revealed significantly higher PA levels among married students, those with high educated mothers, and those who lived far from parks, and lower activity levels among underweight students. Conclusions: This study raises four important determinants for female university students’ PA levels. These factors could be of great importance in the endeavor to prevent the health-threatening increase in physical inactivity patterns and thus non-communicable diseases and obesity where the focus should be on the specific situation and needs of women in Saudi Arabia.

    In this study we report for the first time the distribution of human platelet alloantigens (HPA) in Saudis. These antigens are implicated in the pathophysiology of alloimmune thrombocytopenia. We collected blood samples from 84 healthy male Saudi blood donors. DNA isolated by salting-out and ethanol precipitation was amplified for genes HPA 1-5 using the polymerase chain reaction/sequence specific primer method. We found high HPA-1 polymorphism similar to Caucasians. HPA-4 polymorphism in Saudis was, however, greater than in Caucasians, and more similar to that of the Japanese. These results suggest that both these two HPA systems may be clinically important in Saudis. PMID:11370330

    Meteorologists are required to provide accurate and comprehensive weather information for planning and operational aviation, agricultural, water projects and also for the public. In general, weather phenomena such as thunderstorms over the area between the tropics and the middle latitudes are not fully understood, particularly in the Middle East area, for many reasons such as: 1) the complexity of the nature of the climate due to the wide-ranging diversity in the topography and landscape in the area; 2) the lack of meteorological data in the area; and 3) the lack of studies on local weather situations. In arid regions such as Saudi Arabia, the spatial and temporal variation of thunderstorms and associated rainfall are essential in determining their effects on social and economic conditions. Thunderstorms form rapidly, due to the fact that the significant heating of the air from the surface and the ensuing rainfall usually occurs within a short period of time. Thus, understanding thunderstorms and rainfall distribution in time and space would be useful for hydrologists, meteorologists and for environmental studies. Research all over the world has shown, however, that consideration of local factors like Low Level Jets (LLJ), moisture flux, sea breezes, and the Red Sea Convergence Zone (RSCZ) would be valuable in thunderstorm prediction. The combined effects of enhanced low-level moisture convergence and layer destabilization due to upslope flow over mountainous terrain has been shown to be responsible for thunderstorm development in otherwise non-favourable conditions. However, there might be other synoptic features associated with heavy thunderstorms or cause them, but these features have not been investigated in any research in Saudi Arabia. Thus, relating the local weather and synoptic situations with those over the middle latitudes will provide a valuable background for the forecasters to issue the medium-range forecasts which are important for many projects

    Objectives The present study was conducted to assess the level of awareness and utilization of methods to prevent oral diseases among a group of adult Saudis. Methodology An anonymous, self-administered questionnaire was distributed to patients visiting the clinics of the College of Dentistry, University of Dammam in 2015. The questionnaire assessed the background of the respondents, their dental history, awareness and use of a number of methods available to prevent oral diseases, sources of information about these methods and barriers against their use. Regression analysis was used to assess the factors affecting the use of these practices. Results Brushing was reported to be used by about 60% of respondents whereas fluoride and sealant were less prevalent (≤30%). Dentist was the most frequently reported source of information about preventive methods (60%) and about 40% cited cost and time as the main reasons why they did not use these preventive methods. Awareness and age were associated with using a greater number of the various preventive methods (odds regression coefficient ratio= 0.27 and 0.04). Conclusions Use of preventive methods is not prevalent among Saudi adults and it can be improved by more intensive efforts to increase the awareness of these methods, primarily through dentists.

    This pilot study examines reimbursement practices in private healthcare centers in the Eastern Province of Saudi Arabia. The objective of the study was to assess the extent to which the private healthcare sector in Saudi Arabia follows international best practices in reimbursement, as identified in a literature review. The study examined reimbursement practices in a sample of six private healthcare facilities through the use of similar questionnaire guidelines with each facility. Similarities among the facilities' practices included the use of contracts with insurance companies and the availability of a chargemaster. Differences included the types of reimbursement software used. Bundled payment systems were identified in four facilities but were not examined in all of the facilities studied. International best practices that were not present in any of the facilities in the study included electronic transfer protocols to link healthcare facilities, insurance companies, and banks; the use of reimbursement key performance indicators; the use of diagnosis-related groups; and the integration of disease coding into the reimbursement process. Major findings of this pilot study are that diverse types of reimbursement systems are in use in Saudi healthcare facilities and that these systems are preliminary and are largely unregulated. The authors suggest that regulation and standardization would therefore be easier at this stage than at later stages of the development of private healthcare systems in Saudi Arabia. PMID:26755896

    Objectives To determine the incidence of adverse drug events (ADEs) and assess their severity and preventability in four Saudi hospitals. Design Prospective cohort study. Setting The study included patients admitted to medical, surgical and intensive care units (ICUs) of four hospitals in Saudi Arabia. These hospitals include a 900-bed tertiary teaching hospital, a 400-bed private hospital, a 1400-bed large government hospital and a 350-bed small government hospital. Participants All patients (≥12 years) admitted to the study units over 4 months. Primary and secondary outcome measures Incidents were collected by pharmacists and reviewed by independent clinicians. Reviewers classified the identified incidents as ADEs, potential ADEs (PADEs) or medication errors and then determined their severity and preventability. Results We followed 4041 patients from admission to discharge. Of these, 3985 patients had complete data for analysis. The mean±SD age of patients in the analysed cohort was 43.4±19.0 years. A total of 1676 ADEs were identified by pharmacists during the medical chart review. Clinician reviewers accepted 1531 (91.4%) of the incidents identified by the pharmacists (245 ADEs, 677 PADEs and 609 medication errors with low risk of causing harm). The incidence of ADEs was 6.1 (95% CI 5.4 to 6.9) per 100 admissions and 7.9 (95% CI 6.9 to 8.9) per 1000 patient-days. The occurrence of ADEs was most common in ICUs (149 (60.8%)) followed by medical (67 (27.3%)) and surgical (29 (11.8%)) units. In terms of severity, 129 (52.7%) of the ADEs were significant, 91 (37.1%) were serious, 22 (9%) were life-threatening and three (1.2%) were fatal. Conclusions We found that ADEs were common in Saudi hospitals, especially in ICUs, causing significant morbidity and mortality. Future studies should focus on investigating the root causes of ADEs at the prescribing stage, and development and testing of interventions to minimise harm from medications. PMID:27406640

    BACKGROUND AND AIMS: Saudi Arabia falls in the high prevalent zone of αα and β thalassemias. Early screening for the type of thalassemia is essential for further investigations and management. The study was carried out to differentiate the type of thalassemia based on red cell indices and other hematological parameters. MATERIALS AND METHODS: The study was carried out on 991 clinically suspected cases of thalassemias in Riyadh, Saudi Arabia. The hematological parameters were studied on Coulter STKS. Cellulose acetate hemoglobin electrophoresis and high-performance liquid chromatography (HPLC) were performed on all the blood samples. Gene deletion studies were carried out by restriction fragment length polymorphism (RFLP) technique using the restriction endonucleases Bam HI. STATISTICAL ANALYSIS: Statistical analysis was performed on SPSS 11.5 version. RESULTS: The hemoglobin electrophoresis and gene studies revealed that there were 406 (40.96%) and 59 (5.95 %) cases of β thalassemia trait and β thalassemia major respectively including adults and children. 426 cases of various deletion forms of α thalassemias were seen. Microcytosis was a common feature in β thalassemias trait and (-α/-α) and (--/αα) types of α thalassemias. MCH was a more significant distinguishing feature among thalassemias. β thalassemia major and α thalassemia (-α/αα) had almost normal hematological parameters. CONCLUSION: MCV and RBC counts are not statistically significant features for discriminating between α and β thalassemias. There is need for development of a discrimination index to differentiate between α and β thalassemias traits on the lines of discriminatory Indices available for distinguishing β thalassemias trait from iron deficiency anemia.

    2012-01-01

    Background Quality of work life (QWL) is defined as the extent to which an employee is satisfied with personal and working needs through participating in the workplace while achieving the goals of the organization. QWL has been found to influence the commitment and productivity of employees in health care organizations, as well as in other industries. However, reliable information on the QWL of primary health care (PHC) nurses is limited. The purpose of this study was to assess the QWL among PHC nurses in the Jazan region, Saudi Arabia. Methods A descriptive research design, namely a cross-sectional survey, was used in this study. Data were collected using Brooks’ survey of quality of nursing work life and demographic questions. A convenience sample was recruited from 134 PHC centres in Jazan, Saudi Arabia. The Jazan region is located in the southern part of Saudi Arabia. A response rate of 91% (n = 532/585) was achieved (effective response rate = 87%, n = 508). Data analysis consisted of descriptive statistics, t-test and one way-analysis of variance. Total scores and subscores for QWL items and item summary statistics were computed and reported using SPSS version 17 for Windows. Results Findings suggested that the respondents were dissatisfied with their work life. The major influencing factors were unsuitable working hours, lack of facilities for nurses, inability to balance work with family needs, inadequacy of vacations time for nurses and their families, poor staffing, management and supervision practices, lack of professional development opportunities, and an inappropriate working environment in terms of the level of security, patient care supplies and equipment, and recreation facilities (break-area). Other essential factors include the community’s view of nursing and an inadequate salary. More positively, the majority of nurses were satisfied with their co-workers, satisfied to be nurses and had a sense of belonging in their workplaces

    Little information is known about how Saudi health websites compare internationally. The purpose of this paper is to compare two leading Saudi health websites with leading international health websites. The study was conducted as a convenience sample at a graduate health college in Saudi Arabia. A total of 42 students participated in the study. The study found that, in general, English websites have higher levels of performance with regard to quality of information, authority and objectivity, coverage and currency, and design. However, the respondents considered Saudi health websites to be superior with regard to maintaining privacy and security. The results indicate that much more work is needed in designing Saudi Health to make them more trustworthy and credible. The limitations of this work and future research directions are also discussed. PMID:23388302

    2013-01-01

    Background There are many social and cultural factors affecting the sexual knowledge of adolescents. This study measured the sexual health knowledge level of adolescents and identified its association with role of parents, friends and school environment in adolescent girls in Riyadh, Saudi Arabia. Methods Four hundred and nineteen Saudi female students belonging to intermediate and secondary grades were randomly selected from four public and private girl schools. 255 (69.8%) students were ≤15 years and 164 (39.2%) were >15 years. A self-administered structured questionnaire comprising of socio-demographic information, role of parents and teachers, availability of school curriculum on sexual health was used. Sexual health knowledge was assessed through questions on identification of physical changes during puberty for ≤15 years and separate questions on sexually transmitted infections for >15 years. Results 54% of ≤15years and 70.7% of >15 years had poor sexual health knowledge. Multivariate analysis found determinants for poor sexual health education in ≤15years are: lower education level of both parents (OR 10.87; 95% CI 2.44–48.38), second birth order or more (OR 2.32; 95% CI 1.24–4.33) and absence of school curriculum on sexual health (OR 0.56; 95% CI 0.33–0.95). Determinants for >15 years of age are : mothers with low literacy (OR 3.08, 95% CI 1.42–6.71), as for sources of poor sexual knowledge : parents (OR 10.10; 95% CI 2.70–37.74), schools (OR 6.95; 95% CI 1.95–24.78) maids (OR 4.57; 95% CI 1.26–16.59) and media (OR 5.12; 95% CI 1.29–20.07) were statistically significant factors. Conclusion Government agencies with collaboration of all stake holders should develop policies and programs for implementing and evaluating integrated and comprehensive sexual educational programs for adolescents in Saudi Arabia.

    The purpose of this cross-sectional study was to investigate the prevalence and correlates of diabetic peripheral neuropathy (DPN) in a Saudi population. The study population consisted of 552 diabetic participants with an average age of 53.4 years. Among this population, 62.7% were male and 94.9% had type 2 diabetes. The average body mass index was 31.1 kg/m2. DPN was diagnosed based on a combination of reduced vibration perception measured by neurothesiometer and/or reduced light touch perception evaluated by the 10-g Semmes-Weinstein monofilament, as well as neurological symptoms. Information on socio-demographic variables, smoking status, duration of diabetes, and medications was obtained through interviews by physicians. Body weight, height, waist circumference, blood pressure and clinical markers were assessed following standard procedures. The prevalence of DPN in this population was 19.9% (95% CI, 16.7%-23.5%). In the multivariable analyses, longer duration of diabetes [odds ratio (OR) for every 5-year increase, 2.49, 95% CI, 1.75-3.53], abdominal obesity (OR, 2.53, 95% CI, 1.41-4.55), and higher levels of fasting blood glucose (OR for every 1 mmol/L increase, 1.05, 95% CI, 0.99-1.12), creatinine (OR for every 10 µmol/L increase, 1.07, 95% CI, 0.99-1.14) and white blood cell count (OR for every 106/L increase, 1.08, 95% CI, 1.01-1.16) were associated with higher odds of DPN, while oral hypoglycemic medication use was associated with a lower odds of DPN (OR, 0.47, 95% CI, 0.26-0.85). In this large Saudi population, several correlates for DPN, in addition to glycemic control and diabetes duration, were identified, including abdominal obesity, creatinine and white blood cell count.

    Hand hygiene is an important component of infection control, which is critical to ensuring patients' safety in hospitals. Nursing students are regarded as healthcare workers in training and can also be vehicles of cross-contamination within the hospital. Thus, this study aimed to identify the predictors of hand hygiene practice among Saudi nursing students. A descriptive, cross-sectional, self-reported study was conducted among 198 Saudi nursing students. Knowledge, attitude, and practice of hand hygiene were assessed using the WHO Hand Hygiene Knowledge Questionnaire for Health-Care Workers and its adopted scales. A regression analysis was performed to identify the predictors of hand hygiene practice. The respondents demonstrated moderate knowledge of hand hygiene (mean 13.20±2.80). The majority displayed a moderate attitude toward hand hygiene (52.1%), while only a few reported a poor attitude (13.1%). Approximately 68.7%, 29.8%, and 1.5% of the respondents reported moderate, good, and poor practice of hand hygiene, respectively. Having a good attitude toward hand hygiene, being male, being aware that hand hygiene is an effective intervention in preventing healthcare-associated infections (HAIs), attendance at hand hygiene trainings and seminars, and being in the lower academic level of nursing education were identified as predictors of better hand hygiene practice. The importance of ensuring a positive attitude toward hand hygiene and improving awareness of hand hygiene is emphasized, as are educational interventions. Educational interventions should be implemented to reinforce knowledge and instill a positive attitude toward hand hygiene. PMID:26707706

    BACKGROUND: There is limited information about the prevalence of unethical behavior and how is perceived among health care providers. The aim of this study is to assess such behavior and how is perceived. MATERIALS AND METHODS: This is a cross-sectional study among three groups of professionals. Total participants were 370 and included medical staff, medical residents, and nurses in five medical specialties in four tertiary hospitals in Saudi Arabia (two Ministry of Health Hospitals and two military Hospitals). Participants were asked to rate their agreement with occurrence of 15 “negative” unethical behavior scenarios in their workplace. The scenarios covered areas of “respect for persons”, “interprofessional relationships”, and “empathy with patients”. RESULTS: Majority of respondents agreed that “unethical” behavior occurred in their workplace, including confidentiality being compromised (36.3%), informed consent not taken properly (60.2%), and bad news not well-delivered (62.2%). Other significant area agreement included doctors lacking empathy (47.8%), patient autonomy not fully respected (42.5%), discrimination (41.2%), and being pressurized to write inaccurate reports (31.2%). Respondents in medicine had the lowest rate of agreement and those in psychiatry had the highest (mean of 49.8% and 82.3%, respectively). Respondents with length of employment of less than 6 years had significantly higher agreement that unethical behavior occurs compared to those with length of employment of more than 6 years. Males were more likely than females to agree that unethical behavior occurs. The biggest difference was seen in the behavior of “informed consent not properly taken” with a gender margin of 18.7% (P = 0.001). CONCLUSION: There is high prevalence of behavior that is considered unethical as perceived by various health care workers at Saudi hospitals. PMID:24251232

    Objectives Proper awareness among health professionals about organ donation is important for increasing organ procurement. Personal commitment and attitude of nurses are imperative as they have key role in identifying potential donors. The aim of this study was to compare prevailing knowledge and attitude of undergraduate female Saudi nursing and medical students’ toward organ donation. Methodology A cross sectional questionnaire using 29 item were filled by nursing (n=46) and medical (n=63) students’ at University of Dammam (KSA) during academic year 2014–15, to check and compare their knowledge and attitude about organ donation. The data were analyzed by descriptive statistics; chi square test and bivariate analysis to find out correlation. Results Level of knowledge of nursing group were significantly lower (p=0.000) than medical group while no significant difference in attitude score (p=0.591) between the two groups were found. Major source of knowledge for nursing was media (65.2%) and college/university for medical (50.8%) group. Both groups chose “anyone in need” as preferred recipients’ upon donation (nursing 60.3% and medical 52.2%) and opted “anyone” as donor in case of recipient (nursing 52.2% and medical 49.2%). The results indicate positive correlation between level of knowledge and attitude toward organ donation. Conclusions Nursing students have low knowledge toward organ donation as compared to medical students although they shows positive attitude toward this issue. This study ascertains the need of an effective educational program for nursing students of Saudi Arabia to improve their knowledge regarding organ donation and to raise organ procurement.

    Objectives Rheumatoid arthritis (RA) is often not diagnosed or treated quickly enough to alter outcomes. We aimed to evaluate the lag times from disease onset to first clinical consultation and diagnosis and to identify factors contributing to delayed diagnosis in Saudi Arabia. Methods This retrospective, multicenter study collected data on 250 patients, from six hospitals in Saudi Arabia, who met the 2010 American College of Rheumatology criteria for RA. Results The patients mean age was 43.3±12.0 years (mean disease duration: 6.6±5.8 years). The majority were female (84.8%) and presented with joint pain during RA onset (83.6%). On average, they consulted 4.3±2.5 physicians from the first symptoms to the final diagnosis. The mean time from onset to first physician visit (lag 1) was 6.2±5.5 months, whereas the mean time was 30.2±16.0 months between the initial visit and final RA diagnosis (lag 2). Only 3.2% of patients initially sought consultation from a rheumatologist, while 67.2%, 23.6%, and 6.0% first met with orthopedic surgeons, general practitioners, and non-rheumatologists, respectively. Non-rheumatologists offered diagnoses in 24.4% of cases while rheumatologists diagnosed 75.6%. The absence of early hand/wrist involvement and fatigue were associated with delayed RA diagnosis (long lag 2; p<0.010). Moreover, geographic distribution influenced RA diagnosis, with rural patients experiencing a greater delay than urban patients (p<0.0001). Conclusions Failure of patients to be seen by rheumatologists at RA onset delayed diagnosis and treatment. Thus, RA diagnosis can be accelerated by encouraging early referral to rheumatologists.

    Aim: The aim was to measure the prevalence of smoking and identify its potential predictors among military personnel in Kingdom of Saudi Arabia (KSA). Materials and Methods: This cross-sectional study was carried out among military personnel in the five military regions of KSA between January 2009 and January 2011. The sample of 10,500 military personnel in the Saudi Armed Forces was equally divided among the five regions with a ratio 3:7 for officers and soldiers. A multistage stratified random sampling was used to recruit participants in the four services of the armed forces in the five regions. Information on sociodemographic characteristics with a detailed history of smoking was collected by means of a self-administered questionnaire. Bivariate analysis was used to identify the factors associated with smoking, and multiple logistic regression analysis to discover its potential predictors. Results: About 35% of the sample was current smokers, with higher rates among soldiers. The eastern region had the highest rate (43.0%), and the southern region the lowest (27.5%). Navy personnel had a higher risk of being current smokers (40.6%), and the air defense the lowest risk (31.0%). Multivariate analysis identified working in the navy, and low income as positive predictors of current smoking, while residing in the southern region, older age, years of education, being married, and having an officer rank were negative (protective) factors. Conclusion: Smoking is prevalent among military personnel in KSA, with higher rates in the Navy and Air Force, among privates, younger age group, lower education and income, and divorced/widowed status. Measures should be taken to initiate programs on smoking cessation that involve changes in the environment that is likely to promote this habit. PMID:25374464

    Background: Adolescents who suffer from depression early in life, have an increase in suicidal tendency, anxiety, conduct disorders, substance abuse, and continue to be depressed, later on in life. This study was conducted to identify the prevalence and correlates of depression among adolescent girls in Riyadh city in order to carry out early intervention. Methods: A cross-sectional, school-based survey was conducted among 1028 adolescent girls aged 15–19 years in secondary schools of Riyadh city. Riyadh was divided into clusters and within each cluster, both public and private schools were enrolled. From the selected schools students from grade 10–12 were surveyed. Survey was conducted using a structured questionnaire including the beck depression inventory-II, and questions exploring the correlates of depression. Results: About 30% of participants were found to be depressed. Depression was more prevalent among female adolescents whose household income was <12,000 Saudi Riyal/month (odds ratio [OR] 2.17, confidence interval [CI] 0.97–6.84), did not have a good relationship with peers and family members (OR 4.63, CI 2.56–8.41), lived with single parent or alone (OR 1.77, CI 0.97–3.23), been emotionally abused (OR 3.45, CI 2.56–8.41), and those who had been subjected to physical violence, at least once (OR 3.34, CI 1.89–5.91). Conclusions: Strategies need to be developed to identify early signs and symptoms of depression among Saudi female adolescents. Training can be given to groups of students to help their peers, and also to the teachers to identify, and help students identify early signs of depression and provide them with better-coping strategies to combat progression of depression and anxiety among such adolescents.

    This study explores the experiences of Saudi undergraduate medical students about intimate-area examination (IAE) and sexual history taking (SHT) skills and assesses the barriers and their impacts on students' learning. This survey-based study was performed at 2 Saudi university medical colleges and revealed that most of the students never performed IAE, that is, female breast, male genital, female genital, female pelvic, male rectal, and female rectal. We found that 42.3% students had never taken any sexual history during their course. Both, male and female students reported barriers of patient refusal, mismatched sex, cultural background, ethical factors, lack of supervision, lack of training, and lack of skills. Among the currently used pedagogical techniques, majority of the students were satisfied with real patient-based learning, followed by video and manikin-based learning. The study indicates that Saudi students do not have sufficient experience of IAE and SHT because of above-mentioned barriers along with religious issues. This study suggests that teachers provide positive support to students and that they develop novel, competent teaching-and-learning techniques to meet the skills training of students without compromising on religious, sociocultural, and ethical values of the kingdom.

    Objectives Studies have shown that dentists have a higher incidence of work-related musculoskeletal (MSK) pain than those in other occupations. The risk factors contributing to MSK pain among Saudi dentists has not been fully studied so this study aims to estimate the prevalence of MSK pain and investigate its associated risk factors among dentists in Saudi Arabia. Setting and participants A cross-sectional survey was carried out in the capital city Riyadh, Saudi Arabia, using random cluster sampling. 224 surveys were distributed among dentists with a 91.1% response rate (101 women and 103 men). Outcomes The prevalence of MSK pain and its associated risk factors were investigated. Results 184 (90.2%) respondents reported having MSK pain. Lower back pain was the most commonly reported MSK pain (68.1%). Gender and age were reported to be predictors for at least one type of MSK pain. Older age was associated with lower back pain (OR 1.23; 95% CI 1.00 to 1.50) and women had double the risk of shoulder pain (OR 2.52; 95% CI 1.12 to 5.68). In addition, lower back pain was related to the time the dentist spent with patients (OR 0.28; 95% CI 0.14 to 0.54), while shoulder pain (OR 1.03; 95% CI 1.00 to 1.06) and lower back pain (OR 1.06; 95% CI 1.03 to 1.10) were significantly related to years of experience. Conclusions MSK pain is common among older and female Saudi dentists. Research on the impact of exercise and the ergonomics of the workplace on the intensity of MSK pain and the timing of its onset is required. PMID:27324712

    Background. We conducted this case-control study to determine the risk factors and treatment outcome of infections due to carbapenem resistant Enterobacteriaceae in our institution. Methods. This is a matched case-control study of patients with infection due to carbapenem resistant Enterobacteriaceae (CRE) and carbapenem susceptible Enterobacteriaceae (CSE), from Riyadh, Saudi Arabia, between March 2012 and December 2013. Results. During this period, 29 cases and 58 controls were studied. The mean ages of the cases (55.4 years) and controls (54.7 years) were similar (p = 0.065). Cases had higher mean Charlson comorbidity index (CCI) (3.1) than controls (1.9), p = 0.026. Several factors contributed to infection among the studied population. Prior uses of piperacillin-tazobactam, a carbapenem, a quinolone, and metronidazole were significantly associated with CRE infections. Nine of the cases died compared with 7 of the controls, p = 0.031. Mortality was associated with advanced age, the presence of comorbidities, ICU stay, and receipt of invasive procedures. Conclusions. Infections due to CRE resulted in a significantly increased mortality. Combination antibiotic therapy was associated with reduced mortality. Properly designed randomized controlled studies are required to better characterize these findings. PMID:27144165

    Objectives: The current study aimed to explore the knowledge, perception, and attitude of physicians toward generic medicines in Saudi Arabia. Background: The local market of generic medicine share in Saudi Arabia is low compared to global and regional statistics. The reason for this low market share and the role of physicians has not previously been investigated. The purpose of this study was to assess health practitioner level of perceived knowledge, opinions and attitudes about local generic medication, and identify factors that influence infrequency of generic prescriptions. Methods: A random sample of 231 physicians was recruited from two hospitals in Riyadh (one government one private) and 178 (77%) responded. Information on the physicians’ perceived knowledge, opinions and attitude toward local generic medication was extracted, analyzed and interpreted. Factors that influence infrequent prescription of local generic drugs were identified. Results: Among the 178 participants in the physicians’ survey, 76% and 47% reported that they are knowledgeable about the terms “generic” and “bioequivalence” respectively, while 44% reported that they are able to explain bioequivalence to their patients. Approximately 52% of physicians reported that local generics should be substituted for brands if suitable for the case, and 21.9% reported that they believe SFDA approved local generics are therapeutically equivalent to their brands. Clinical effectiveness was reported by 71.9% of physicians as the most influential factor effecting prescription of brand over local generic medication. The three independent significant predictors for infrequent prescription of local generics among physicians: Government sector employment (OR = 3.74, [95%CI 1.50–9.43]), consultant level (OR = 3.94, [95%CI 1.50–10.31]) and low level of knowledge about local generics (OR = 4.11, [95%CI 1.56–10.84]). Conclusion: The low market share of local generics medicines attributed

    [Purpose] To review the physical therapy educational program model, professional curriculum, and gender representation at major universities, as well as the quality and scope of physical therapy practice in Saudi Arabia. [Methods] Information regarding course curriculum, gender representation, and the quality and scope of physical therapy practice was collected from six universities in Saudi Arabia, the Saudi Physical Therapy Association, and the Saudi Health Commission. [Results] The first bachelor’s degree course of physical therapy was started in Saudi Arabia more than 30 years ago. In the last 10 years, the number of universities offering a bachelor’s degree in physical therapy has risen from 6 to 16, of which 14 are governmental and two are private. The 5- to 6 year bachelor’s degree program in physiotherapy includes an internship and preparatory prerequisite courses. Postgraduate study in physical therapy was introduced in 2000. Most universities offer segregated physical therapy courses for male and female students. [Conclusion] The enrollment of students in physical therapy programs in Saudi Arabia is gradually increasing. There are many opportunities to extend the scope of practice and contribute to the health needs of the Arab population and international communities. PMID:26157276

    The purpose of this study was to reveal the occurrence of nail-patella syndrome (NPS) in Saudi Arabia together with the detection of abnormal attachment of lateral meniscus in the left knee and new surgical procedures applied to the right and left knee, reported for the first time in this study. This was a case study of a 23-year-old young man presenting with bilateral knee pain, giving way and locking since the age of 15 years. Clinically, most of the NPS features were noted, including ocular problems. The complex features affected both knees, especially the previous attempted surgeries for recurrent dislocation of patellae. Deficient ligaments were reconstructed using the Leeds-Keio ligament, starting with the right knee and continuing with the left knee 6 months later. Early and late follow-up showed favorable outcome of surgery revealed as independent ambulation and stable right and left knees. In conclusion, NPS, although rare, presents a complex problem and unexpected surgical outcome, and we recommend this procedure with close follow-up. PMID:15266233

    Background Trisomy 21 (T21) is a congenital disorder characterized by triplication of Chromosome 21 components. Patients with T21 have an increased risk of acquiring periodontal disease due to their inability to maintain good oral hygiene. Consequently, it is important to determine an approach for disease prevention in this population. Aim The purpose of the study was to assess the periodontal health, through the prevalence of gingivitis and plaque, among children with T21 living in Riyadh, Saudi Arabia. Subjects and method This study included 93 children with T21 and 99 age- and gender-matched children without T21 between the ages of 7 and 15 years. Parents were informed about the study and provided informed consent. Trained examiners using standardized tools assessed the prevalence rates of gingivitis and plaque in all children. Results Gingivitis prevalence was elevated among T21 children (46.9%) compared to controls (34%) in all arch sextants except the mandibular middle (P < 0.01). Comparing the two groups, the prevalence of plaque was higher in the maxillary right sextant of the T21 group and the mandibular middle sextant of the control group (P < 0.05). Conclusion T21 children have significantly elevated plaque levels, resulting in greater prevalence of gingivitis, compared to healthy children. Preventive measure, such as oral health awareness programs, should be delivered early to parents and continued at school to encourage and motivate children. PMID:26644759

    Abha is the capital of Asir province in Saudi Arabia. It is situated 2200 meters (7200 ft) above the sea level in the fertile mountains of the south-western Saudi Arabia. One of the most important structures of this region is Abha dam that acts as a barrier that impounds water or underground streams thereby retaining the ground water of the region. With the passage of time, various environmental factors such as ground movement, wind and changes in temperature may have significant effect on these various structure factors and may lead to invisible cracks and other structural defects. Because the dams and tunnels are prone to sudden collapse, there is potential great risk to lives of the people and significant economic loss in this area. The use of the ground penetrating radar (GPR) and electric resistivity techniques is a non-invasive scan and could assess the conditions of various built structures as well as the earth beneath or surrounding it. So the GPR system with appropriate types of antennas (1.5 GH, 1 GH, 400 MH and 100 MH) and electrical resistivity in one dimension (VES) and two dimensions (electrical profiling and imaging) is used in this work. This work aims to investigate the dam structure, developing cracks or areas of increased moisture. Also to study the surrounding areas to detect seepage from pond that may affect nearby buildings and the dam itself. It reveals that, the depth of water bearing layer ranges from 2 m to 10 m, where the three geoelectric layers are present. The first layer has resistivity values ranging from 44 Ω m-1200 Ω m with thickness ranging from 3 m to 18 m that is interpreted as the wadi deposits. The second layer having resistivity values from 11 Ω m to 137 Ω m is interpreted as the water saturated in the fractured basements. The third layer of resistivity values ranging from 2200 Ω m to 90,000 Ω m is interpreted as dry, massive basements. The GPR results provided internal images of the slab, showing its morphology, areas

    Introduction: All medical schools in Saudi Arabia have English as the primary official medium of instruction. Most of the high school education, however, is delivered in Arabic and hence the transition to an English based learning environment tends to be difficult for some students. Our study aims to correlate English language proficiency with academic performance among medical students in their preparatory year. Methods: A cross-sectional study design was used. Test scores of 103 preparatory year students (54 female and 49 male) were analyzed after the students completed an English language course and medical introductory course in their preparatory year. The total score obtained in the English course assessment was compared to each component of the medical content assessment. Results: A significantly positive correlation (Spearman's Rho, at 0.01 levels) was seen between the scores of the English exam and the written exam (P <0.001) and the oral exam (P = −0.003) parts respectively of the medical examination. Significant correlation with the English exam score was not obtained for the other components of the medical assessment, namely; student assignments, presentations and portfolios. Conclusion: English language proficiency is an important factor in determining academic proficiency of medical students in our college at the preparatory year level. PMID:26629471

    Background The results of a qualitative study carried out in four developing countries (Cuba, Thailand, Saudi Arabia and Argentina) are presented. The study was conducted in the context of a randomised controlled trial to test the benefits of a new antenatal care protocol that reduced the number of visits to the doctor, rationalised the application of technology, and improved the provision of information to women in relation to the traditional protocol applied in each country. Methods Through focus groups discussions we were able to assess the concepts and expectations underlying women's evaluation of concepts and experiences of the care received in antenatal care clinics. 164 women participated in 24 focus groups discussion in all countries. Results Three areas are particularly addressed in this paper: a) concepts about pregnancy and health care, b) experience with health services and health providers, and c) opinions about the modified Antenatal Care (ANC) programme. In all three topics similarities were identified as well as particular opinions related to country specific social and cultural values. In general women have a positive view of the new ANC protocol, particularly regarding the information they receive. However, controversial issues emerged such as the reduction in the number of visits, particularly in Cuba where women are used to have 18 ANC visits in one pregnancy period. Conclusion Recommendations to improve ANC services performance are being proposed. Any country interested in the application of a new ANC protocol should regard the opinion and acceptability of women towards changes. PMID:12756055

    Background: Faith healers usually offer unorthodox therapies to their clients who present with an array of physical and psychological symptoms suggestive of the evil eye, jinn possession, and magic. Objective: This exploratory pilot study aims to analyse the pattern of narrated symptoms and treatments given by faith healers practising in the Al-Qassim region, Saudi Arabia. Method: Forty five faith healers who consented to this study were given a predesigned, self-administered, semistructured questionnaire to collect the relevant data. Results: Notably, most faith healers have a poor repertoire of psychiatric symptoms, which could not specifically differentiate the three spiritual disorders. They tend to recommend an array of therapies rooted in religious concepts for the treatment of their clients who, they claim, show substantial improvement in their mental suffering. Conclusion: The revealed symptomatology of each disorder alone may not be specific but it certainly helps them not only to identify these disorders but also to prescribe unconventional therapies. Future research should look systematically into the diagnostic and treatment methods for these disorders. PMID:23012035

    Although health data standards are perceived to be the essential solution for interoperability barriers within medical IT systems, the level of adoption of those standards still remains frustratingly low. Little is known about the barriers facing their adoption within the healthcare organizations context. In addressing this gap in the literature, based on IT related standards adoption theories such as Diffusion of Innovation Theory and the theories surrounding the Economics of Standards, a qualitative multiple-case study was undertaken in Saudi Arabia to investigate those barriers. The results exposed that few standards were adopted because of four broad reasons, managerial, technical, educational and governmental. While some of the findings can be rooted to those related standards theories, others can be underpinned through the normative literature. Core barriers are the lack of a national regulator and a data exchange plan, and the lack of an adequate policy regarding medical IT systems and information management and national healthcare system; also important are technical barriers and the switching costs to the standards. The outcome of this study can be used in forming effective interventions when planning to use health data standards and, in particular those in developing countries. PMID:23321966

    2014-01-01

    Background Although the occurrence of malnutrition in hospitals is a growing concern, little is known about how hospital staff understand the care that nurses provide to patients with malnutrition. The purpose of this study was to explore nurses’ views and experiences of caring for malnourished patients in Saudi Arabia (KSA). Methods Using a qualitative explorative design, fifteen nurses were interviewed as part of a purposive sample hospital staff. The transcripts were analyzed using latent content analysis. Results The nurses spontaneously and consistently linked malnutrition with physical inactivity. The two main categories, which emerged, were: ‘Potentials for nurses to provide good nutrition and physical activity’, and ‘Having the ability but not the power to promote proper nutrition and physical activity’. These arose from the subcategories: Good nursing implies providing appropriate health education; Acknowledging the Mourafiq (sitter) as a potential resource for the nursing, but also as a burden; Inadequate control and lack of influence; Cultural diversity and lack of dialog; and Views of women’s weight gain in KSA society. Conclusions The nurses felt they have the capacity and passion to further improve the nutrition and activity of their patients, but obstacles in the health care system are impeding these ambitions. The implications for nursing practice could be acknowledgement of the nurses’ views in the clinical practice; culturally adjusted care, improved communication and enhanced language skills.

    This study aimed at establishing updated data on iodine nutrition among schoolchildren in Saudi Arabia. A cross-sectional cluster survey among schoolchildren aged 8-10 years was conducted during February-April 2012. Children were clinically examined for goitre, urine and household salt samples were collected to estimate urinary iodine concenteration (UIC) and iodine content in salt. The overall goitre prevalence at the national level among 4 016 children was 4.2%. The prevalence was < 5% in all regions of the country except southern region with a prevalence of 12.7%. The median UIC of 2224 samples was 133 μg/L, with 74.3% of the surveyed children with UIC ≥ 100 μg/L. Analysis of salt samples (n = 4242) revealed that 69.8% of households were consuming adequately iodized salt. The findings suggest iodine sufficiency at the national level, however southern region still has a goitre prevalence of mild degree severity and the proportion of households consuming adequately iodized salt is still below recommendations.

    In Saudi Arabia, center-pivot, swing-arm irrigated agriculture complexes such as the one imaged at Jabal Tuwayq (20.5N, 45.0 E) extract deep fossil water reserves to achieve food crop production self sufficiency in this desert environment. The significance of the Saudi expanded irrigated agriculture is that the depletion of this finite water resource is a short term solution to a long term need that will still exist when the water has been extracted.

    Aerosol particles from desert dust interact with clouds and influence climate on regional and global scales. The Riyadh (Saudi Arabia) aerosol campaign was initiated to study the effects of dust particles on cloud droplet nucleation and cloud properties. Here we report the results of individual-particle studies of samples that were collected from an aircraft in April 2007. We used analytical transmission electron microscopy, including energy-dispersive X-ray spectrometry, electron diffraction, and imaging techniques for the morphological, chemical, and structural characterization of the particles. Dust storms and regional background conditions were encountered during four days of sampling. Under dusty conditions, the coarse (supermicrometer) fraction resembles freshly crushed rock. The particles are almost exclusively mineral dust grains and include common rock-forming minerals, among which clay minerals, particularly smectites, are most abundant. Unaltered calcite grains also occur, indicating no significant atmospheric processing. The particles have no visible coatings but some contain traces of sulfur. The fine (submicrometer) fraction is dominated by particles of anthropogenic origin, primarily ammonium sulfate (with variable organic coating and some with soot inclusions) and combustion-derived particles (mostly soot). In addition, submicrometer, iron-bearing clay particles also occur, many of which are internally mixed with ammonium sulfate, soot, or both. We studied the relationships between the properties of the aerosol and the droplet microphysics of cumulus clouds that formed above the aerosol layer. Under dusty conditions, when a large concentration of coarse-fraction mineral particles was in the aerosol, cloud drop concentrations were lower and droplet diameters larger than under regional background conditions, when the aerosol was dominated by submicrometer sulfate particles.

    Data about the stigmatization of persons living with HIV/AIDS in Saudi Arabia are scarce. Recent statistics from Saudi Ministry of Health showed that 77% of HIV-positive Saudis were males. The present study analyzed data from 162 Saudi male college students. The findings suggest that students who knew less about HIV/AIDS were more likely to stigmatize persons living with HIV/AIDS than those who knew more. Neither degree of religiosity nor worry about HIV infection was related to AIDS stigma. However, AIDS-related shame was the best predictor of AIDS stigma. The findings of this study point to important suggestions for AIDS prevention programs in Saudi Arabia. PMID:20592063

    Background Trisomy 21 (T21) is a genetic disorder stemming from a chromosomal abnormality and characterized by general and mental retardation. Depending on the population, T21 is known to affect 1 in every 600–2000 live births. The current literature provides a mixed view on the oral health status of T21 individuals. Aim To establish the prevalence of dental caries, malocclusion, and trauma amongst children with T21 compared with non-T21 children in Riyadh, Saudi Arabia. Methods This cross-sectional study recruited non-T21 and T21 children between the ages of 7–15 years who were studying at the Saut Society. After informed consent was obtained from parents and both groups were matched by age and gender, trained examiners screened children at the dental clinic of King Saud University to record the presence of dental caries, malocclusion, and trauma in both groups. Results While there was no statistical difference between the two groups with regard to the mean decayed, missing, and filled teeth (DMFT) index (2.66 for T21 versus 3.11 for controls), T21 children had a higher prevalence of incisal fractures compared to the control group (24.73% versus 4.95%, respectively) and that was statistically significant (P < 0.05). There were also highly significant group differences concerning the prevalence of malocclusion. Therein, 45% of T21 children had a Class III incisor relationship compared with 8% of control children, and 50% of T21 children had a Class III molar relationship compared with 8% of control children. Conclusions While there was no significant difference in the incidence of caries between children with and without T21, practitioners should be aware of the disparities in malocclusion and trauma in this vulnerable population.

    We have carried out a seismic noise study in order to understand the noise level at three selected locations at King Fahd University of Petroleum and Minerals (KFUPM), Dhahran, Saudi Arabia. The main purpose is to select a suitable site with low seismic noise and good signal-to-noise ratio for our new broadband seismic station. There are several factors involved in the selection of a site location for a new station. Most importantly, we need to strike a balance between a logistically convenient site versus a technically suitable site. As a starting point, we selected six potential sites due to accessibility and proximity to the seismic processing center laboratory in the Department of Earth Sciences (ESD) at KFUPM. We then eliminated two sites that are relatively close to possible low-frequency noise sources. We have considered many possible noise sources which include: vehicle traffic / heavy machinery, the direct path of air flowing from air conditioning vent, tall trees / power poles and metal doorways. One more site was eliminated because the site was located in the open where it experiences maximum wind speed which is considered a major source of noise. All three potential sites are situated within the Dammam Dome where both lower middle and upper Rus Formations are exposed. The upper Rus is mainly made up of fine grained chalky limestone and the lower Rus is made up of alternation of marls and thin dolomitic limestone. The area is not known for any major faults and considered very low seismicity and hence the identification of seismoteconic features is not required. Before conducting the noise study, we calibrated and tested the seismic recording system, which was recently acquired by the ESD at KFUPM. The system includes a seismic recorder and a sensor with a GPS device. We deployed the system in order to measure the low-frequency background noise. Knowing the low frequency noise will help in predicting the high-frequency noise. The recording systems were

    An experiment was designed, assembled and carried out at the Hada Al-Sham Experimental station in the dry western part of Saudi Arabia, to procure dew duration data at two different heights in a corn canopy, from the time of emergence (average plant heights about 30 cm) until harvest time (average height about 230 cm). Micrometeorological, together with canopy and additional environmental measurements, were taken to deduce the latent heat flux involved in dew onset and dry-off. The micrometeorological measurements included leaf and air temperatures, relative humidity, net radiation, wind speeds and direction, while other observations included canopy heights, leaf width, leaf area index (LAI), soil temperature, soil moisture, and dew duration. The energy balance approach (Penman-Monteith), along with boundary layer resistance theory around the leaf surface, were used to estimate the latent heat flux involved in the dew process. It was found that at the beginning of the season dew usually started to form on the lower part of the canopy at an average of three hours before it started to form in the upper part. On the other hand, as the canopy reached the mature stage, dew formation on the upper part of the canopy started an average of two hours before it started to form on the lower part. It took averages of one hour and an hour and half after sunrise, for the lower and upper part of the canopy to dry-off respectively. A linear regression analysis of the latent heat and environmental variables showed high correlations with net radiation, leaf and air temperatures, relative humidity, soil temperature at 2cm depth from top of the furrow at both canopy heights for the whole growing season, whereas wind speed showed high correlation for the upper part of the canopy only. It is suggested that many more studies are necessary to increase understanding of the dew process but less comprehensive instrumentation would probably be adequate.

    In this prospective study we wanted to determine whether perceived stress over time among students in the Preparatory Year of King Saud University (KSU) predisposes them to cardiometabolic abnormalities. A total of 110 apparently healthy Saudi students (35 men and 75 women enrolled during the 2010−2011 academic year) were included. Perceived stress was determined at baseline and 1 year later. Anthropometrics were obtained and morning fasting serum glucose, lipid profile and cortisol were measured at both times. Perceived stress was noted among 48.2% of subjects at baseline and was not significantly different after follow-up, with 45.4% scoring high. In men, the prevalence of perceived stress was 48.6% at baseline (13 out of 35) and 37.1% at follow-up (13 out of 35), while in women it was 48% at baseline and 49.3% at follow-up. Interestingly, significant improvements in the blood pressure and lipid profiles, with the exception of HDL-cholesterol, were observed in both men and women, while fasting glucose also improved in women. Serum cortisol was inversely associated to fasting glucose, and total- and LDL-cholesterol (p-values 0.007, 0.04 and 0.04, respectively). These data are opposite to findings in students entering Western universities, in whom increasing stress and a deteriorating cardiometabolic profile have been repeatedly noted. Perceived stress and morning cortisol levels among students of the Preparatory Year in KSU remained constant for both genders over time, yet an improved cardiometabolic profile was observed, suggesting good adaptation among our pre-college students in their first year of university life.

    The aerosol index (AI) from the Total Ozone Mapping Spectrometer (TOMS) satellite and meteorological parameters from National Center for Environmental Prediction and the National Center for Atmospheric Research (NCEP/NCAR) reanalysis datasets were used to examine seasonal dust cases in northern Saudi Arabia. Considering all seasons, winter has the fewest dust cases, whereas summer has the most dust cases. Synoptically, surface high-pressure systems in the eastern and western regions are important for the occurrence of dust cases over the northern Arabian Peninsula. When the eastern high pressure prevails, the effects of the Indian low-pressure system on the Arabian Peninsula are weakened or become nonexistent. The extension of the western high-pressure system toward the southeast provides an opportunity for a low-pressure system over Southeast Africa to connect with the Indian low-pressure system, which increases the width of the low-pressure trough and affects the Arabian Peninsula by increasing the amount of dust over the region. At 850 hPa, the weather systems typically rotate clockwise between winter and autumn. In winter, cyclonic systems prevail in the northern region, while anticyclonic systems prevail in the south. The systems are oriented toward the northeast in spring, the west in summer, and the southeast in autumn. Moreover, northern cyclones at 500 hPa shrink as they move northward and the maximum wind speed at 250 hPa decreases from winter to summer. Furthermore, the case study confirms that a change in the relative strength of the pressure systems and a change in the orientation of the isobars (contours) affect the amount of dust over the area. When the orientation of the isobar (contour) lines become strictly north to south or east to west, the amount of dust decreases and vice versa.

    OBJECTIVES: To compare QuantiFERON-TB gold in tube (QFT-GIT) test with tuberculin skin test (TST) in detecting latent tuberculosis infection (LTBI) among a general population in Saudi Arabia. METHODS: A population-based cross-sectional study was conducted between July 2010 and March 2013 among individuals randomly selected from the list of those receiving care at primary healthcare centers in three provinces of Saudi Arabia; Central, Western, and Eastern provinces. Those younger than 5 years, immunocompromised, had a current or previous history of active TB, LTBI, or who were receiving anti-TB medications were excluded. Informed consent was obtained before the study questionnaire was completed. Participants were then evaluated for LTBI using QFT-GIT test followed immediately by TST. RESULTS: Of the 1369 subjects included in the final analysis, QFT-GIT was positive in 124 (9.1%) and TST was positive in 127 (9.3%). Positive concordance was observed in 49 (3.6%) subjects while negative concordance was observed in 1167 (85.2%) subjects. The overall agreement between the two tests was 88.8% with a significant kappa (κ) test (κ = 0.332, P < 0.001). Concordance was significantly higher in younger age, female gender, single status, students, primary education, living in middle-sized families, and never smoked. CONCLUSIONS: The overall agreement of TST and QFT-GIT for the detection of LTBI among a Saudi general population was 88.8%. QFT-GIT is probably comparable to TST for detecting LTBI in an intermediate TB burden country with high at birth bacille calmette guerin vaccination coverage. Further prospective studies are needed to compare the ability of both tests to predict TB disease. PMID:27512509

    Background There is no consensus and a limited evidence base for choice of contrast agents (CA) in angiography. This study evaluated the impact of iohexol and iodixanol CA on fibrinolytic factors (tissue plasminogen activator [t-PA] and plasminogen activator inhibitor-1 [PAI-1]), as well as platelet-monocyte conjugates in cardiac patients undergoing elective angiography in a double-blind, randomised parallel group study. Methods Patients (men, 50–70 years old; n = 12) were randomised to receive either iohexol (Omnipaque; n = 6) or iodixanol (Visipaque; n = 6) during elective angiography at Raigmore Hospital, Inverness, UK. Arterial and venous blood samples were drawn prior to CA delivery and following angiography. Assessment of platelet-monocyte conjugation, t-PA and PAI-1 antigen and activity was conducted in samples pre- and post-angiography. Outcome Plasma t-PA antigen was depressed equally in the study groups after angiography, but there was a greater reduction in PAI-1 antigen in the group receiving iodixanol. These findings corresponded to a substantial reduction in t-PA activity in patients receiving iohexol, with no change in those receiving iodixanol (P = 0.023 between the CA groups). Both CAs caused a reduction in platelet-monocyte conjugation, with no difference between the groups. No adverse events were reported during the trial. Conclusion Avoiding reduced plasma t-PA activity might be an important consideration in choosing iodixanol over iohexol in patients at risk of thrombosis following angiography. The trial is registered on the ISRCTN register (ISRCTN51509735) and funded by the Coronary Thrombosis Trust and National Health Service (Highland) R&D Endowments.

    This study compared efficacy of two polyvalent antivenoms (Saudi Arabian and Egyptian), against lethality and pathophysiological changes of Leiurus quinquestriatus quinquestriatus (LQQ) scorpion venom in mice. Additionally, the study examined whether treatment with selected ion channel modulators, lidocaine, nimodipine or amiodarone would be effective, alone or combined with the antivenoms. The protein concentration of the Saudi antivenom was 1/3 of Egyptian, indicating lesser immunogenicity, while both preservative contents were within limits. In immunodiffusion experiments, both exhibited prominent precipitin bands indicating high concentrations of specific antibodies. Neutralizing capacities (60-70 LD(50)) stated on labels were confirmed. Both antivenoms significantly (P < 0.001) prolonged survival time (from 26.9 +/- 1.18 min, 100% dead with venom to 224-300 min, 0-30% dead) of envenomed mice, whether injected iv before or 5 min after venom. Injection of either antivenom plus ion channel modulators, gave comparable results to that observed in mice treated with antivenoms alone. The Na(+) channel blocker lidocaine and the Ca(2+) channel blocker nimodipine on their own significantly protected the animals (P < 0.05), but to a lesser extent. The two antivenoms, significantly ameliorated the venom-evoked changes in serum LDH (P < 0.001) and CKMB (P < 0.01) plus cardiac TNFalpha and nitrate/nitrite levels (P < 0.001). When combined with lidocaine or nimodipine, the effects were not greater than antivenom alone. Moreover, the antivenoms ameliorated characteristic venom-evoked changes in the isolated perfused Langendorff hearts. Lidocaine and amiodarone were more effective than nimodipine. In Conclusion both Saudi and Egyptian antivenoms protected mice from the pathological and lethal effects of LQQ scorpion. Sodium and calcium channel blockers, lidocaine and nimodipine, may be useful when antivenoms are not available. PMID:19931297

    Aims The prevalence of diabetic nephropathy and its risk factors have not been studied in a society known to have diabetes epidemic like Saudi Arabia. Using a large data base registry will provide a better understanding and accurate assessment of this chronic complication and its related risk factors. Methodology A total of 54,670 patients with type 2 diabetes aged ≥25 years were selected from the Saudi National Diabetes Registry (SNDR) and analyzed for the presence of diabetic nephropathy. The American Diabetes Association (ADA) criterion was used to identify cases with microalbuminuria, macroalbuminuria and end stage renal disease (ESRD) for prevalence estimation and risk factor assessment. Results The overall prevalence of diabetic nephropathy was 10.8%, divided into 1.2% microalbuminuria, 8.1%macroalbuninuria and 1.5% ESRD. Age and diabetes duration as important risk factors have a strong impact on the prevalence of diabetic nephropathy, ranging from 3.7% in patients aged 25–44 years and a duration of >5 years, to 21.8% in patients ≥65 years with a diabetes duration of ≥15 years. Diabetes duration, retinopathy, neuropathy, hypertension, age >45 years, hyperlipidemia, male gender, smoking, and chronologically, poor glycemic control has a significantly high risk for diabetic nephropathy. Conclusion The prevalence of diabetic nephropathy is underestimated as a result of a shortage of screening programs. Risk factors related to diabetic nephropathy in this society are similar to other societies. There is thus an urgent need for screening and prevention programs for diabetic nephropathy among the Saudi population. PMID:24586457

    Background Improper disposal of medication has several possible consequences such as childhood poisoning, environmental pollution, a negative impact on wildlife, and antibiotic resistance. The number of studies conducted to characterize pharmaceutical disposal practices is limited, particularly in the Middle East. Objective The aim of this cross-sectional study was to examine the behaviour of individuals with respect to the disposal of expired and unused medications. Furthermore, we aimed to identify the best methods of education regarding appropriate, safe disposal of medication. Setting The study was carried out in King Khalid University Hospital (KKUH), and King Saud University (KSU), during a 3-month period from February 2015 to April 2015. Method Twelve hundred patients were randomly selected from KKUH and KSU. Participants were invited to complete paper-based questionnaire with self enumeration. Pilot testing was conducted and involved 50 randomly selected participants. Main outcome measures The proportion of expired medications present in the home and their therapeutic groups, disposal methods of expired and unused medications, and preferred educational methods regarding safe and proper disposing of medications. Results A substantial proportion (79.15 %) of respondents disposed of unwanted medication via household waste, while a small proportion (1.70 %) returned unwanted medication to a pharmacy. Although currently practised disposal methods are undoubtedly unsuitable, 70.20 % of respondents considered finding appropriate, safe methods via which to dispose of unwanted medication their responsibility, and 78.6 % expressed an interest in receiving information concerning the correct disposal of unwanted medication. Conclusion We have demonstrated that a low percentage of respondents have ever received information regarding correct medication disposal. Moreover, the results have shown that over half of the respondents store antibiotics in their households

    The Mahd adh Dhahab mine, located about 280 km northeast of Jiddah, Kingdom of Saudi Arabia, has yielded more than 2 million ounces of gold from periodic production during the past 3,000 years. A new orebody on the southern side of the ancient workings, known as the South orebody, is being developed by Gold Fields-Mahd adh Dhahab Limited. A suite of samples was collected from the newly exposed orebody for preliminary mineralogic, stable isotope, fluid inclusion, and geochemical studies. The Mahd adh Dhahab deposit is in the carapace of a Proterozoic epizonal rhyolite stock that domed pyroclastic and metasedimentary rocks of the Proterozoic Halaban group. Ore of gold, silver, copper, zinc, tellurium, and lead is associated with north-trending, steeply dipping quartz veins in a zone 1,000 m long and 400 m wide. The veins include an assemblage of quartz-chlorite-pyrite-hematite-chalcopyrite-sphalerite-precious metals, which is similar to the mineral assemblage at the epithermal deposit at Creede, Colorado. The primary ore contains abundant chalcopyrite, sphalerite, and pyrite in addition to a complex precious metal assemblage. Gold and silver occur principally as minute grains of telluride minerals disseminated in quartz-chlorite-hematite and as inclusions in chalcopyrite and sphalerite. Telluride minerals include petzite, hessite, and sylvanite. Free gold is present but not abundant. All of the vein-quartz samples contained abundant, minute inclusions of both low-density, vapor-rich fluids and liquid-rich fluids. Primary fluid inclusions yielded homogenization temperatures of from 110? to 238? C. Preliminary light-stable isotope studies of the sulfide minerals and quartz showed that all of the d34S values are between 1.2 and 6.3 per mil, which is a typical range for hydrothermal sulfide minerals that derive their sulfur from an igneous source. The data-suggest that the sulfide sulfur isotope geochemistry was controlled by exchange with la large sulfur isotope

    Cloud droplets nucleate on aerosol particles termed cloud condensation nuclei (CCN). It is well known that a larger number concentration of CCN results in a larger number concentration of droplets in developing cumulus clouds. However, the conditions where dust particles can serve as cloud condensation nuclei (CCN) and hence change cloud droplet concentration and precipitation formation processes is uncertain. Aircraft measurements of cloud droplet concentration between 13:20 and 13:30 UTC during the 9 April 2009 flight near Riyadh, Saudi Arabia, show total cloud droplet concentration (3-50 µm in diameter) of 800 to 1200 #/cm-3 at a altitude of 18000 ft. Typical cloud droplet concentration for this type of cloud in the Riyadh region is approximately 400 #/cm-3 and is typical of observation made between 13:00 and 13:20 UTC during the 9 April 2009 flight at 18,000 ft. Photographs of ice accumulation on the unprotected leading edge of the aircraft’s wing due to the freezing of super cooled droplets show a color changed from white during the time of low droplet number condensation to brown during the high droplet number concentration. It is hypothesized that high droplet number concentration observations were the result of ingestion of a large about of dust particles by the cloud. : Case Study of the 9 April 2009 ‘Brown’ Cloud: Observations of Usually High Cloud Droplet Concentrations in Saudi Arabia.

    Studies in other countries, including countries with mandated reporting by professionals and a long history of recognition of the problem, have found child abuse to be seriously under reported. This population-based pilot study was conducted to determine the magnitude of adolescents' exposure to CAN at home, and to identify ethical and methodological challenges to conducting a survey on a culturally sensitive subject. This cross-sectional study was carried out in Al-Kharj city in 2011-2012. Through a stratified multistage cluster random sampling of schools, a sample of adolescents (15-18 years) were identified and invited to participate. The ISPCAN Child Abuse Screening Tool-Child: Home version (ICAST-CH) was used for data collection. The previous year's incidence of physical, psychological, and sexual abuse, neglect, and exposure to violence were assessed. A total of 2,043 students participated in the study (mean age, 16.6 years; 58%, female). The incidence of psychological abuse, physical abuse, exposure to violence, neglect, and sexual abuse were 74.9%, 57.5%, 50.7%, 50.2%, and 14.0%, respectively. Female participants were at higher risk for psychological and physical abuse, exposure to violence, and neglect, but not for sexual abuse. The rates and gender distribution of CAN at home differ from findings of health-based records. Our results are comparable to other regional population-based studies. Thus, population-based data are necessary to inform and guide professionals and decision makers for prevention policies and resource allocation. Insights to ethical and methodological challenges surrounding the sensitive nature of this type of study are discussed. PMID:25220480

    Objective Domestic violence is a major public health problem. A wide range of health hazards result from violence against women directly, or from its long-term consequences. The objective of this study is to determine health related consequences of domestic violence against women. Method A community based cross-sectional study was carried through online survey; convenience sample was taken during the period between December 2013 and February 2014. 421 women completed the survey, who met the inclusion criteria and accepted willing to be a part of this study. The data was collected through online survey website. A validated Arabic version of NorVold Domestic Abuse Questionnaire (NOVAQ) was used as a tool to assess domestic violence among the study sample. Analysis was performed using SPSS, version 18.0. Results A total of 421 women participated in the survey. There was no significant correlation between socio-demographic characteristics and being abused or not. However, by further analysis we found more sexual abuse among non-working women P=0.048. There was significant correlation between abused women and general health status, doctor visits, depression, insomnia, and somatic symptoms. Conclusion The consequences of abuse are profound, extending beyond the health of individual to affect the well-being of entire community. So, we recommend to increase community awareness through national awareness campaign, national prevalence survey of domestic violence and well trained health professionals for assessing domestic violence cases.

    Phytochemical study of the CH(2)Cl(2) soluble fraction of the aerial parts of R. natalensis resulted in the isolation and identification of six flavonoid derivatives, β-amyrin and β-sitosterol glucoside (daucosterol). The isolated compounds were identified utilizing physical, chemical and different spectral methods including UV, 1D- 2D-NMR and MS. The compounds were identified as four flavanones; 7-O-methyl hesperetin (1), 7-O-methyl naringenin (4), (-)-homoeriodictyol (eriodictyonone) (5), eriodictyol-7-methyl ether (6) and two flavones; 7-O-methyl isokaemferide (2) and genkwanin (3). The isolated compounds as well as some available standards representing structurally similar flavones and flavanones were used to study their antioxidant potential using DPPH and try to explore the impact of structures on the antioxidant activity. In other assays flavanones were less active than flavones as antioxidant due to lack of the C-4 carbonyl group in conjugation with 2,3-double bond. However, in DPPH assay based on the ability of molecules to donate hydrogen flavanones were found more active than flavones. PMID:26826843

    Phytochemical study of the aerial parts of Ficus palmata utilizing liquid–liquid fractionation and different chromatographic techniques resulted in the isolation of a new isomer of psoralenoside namely, trans-psoralenoside (5) in addition to, one triterpene: germanicol acetate (1), two furanocoumarins: psoralene (2), bergapten (3), one aromatic acid vanillic acid (4) and the flavone glycoside rutin (6). Structures of the isolated compounds were established through physical, 1D- and 2D-NMR and MS data. The total extract and fractions of the plant were examined in vivo for its possible effects as hepatoprotective, nephroprotective, antiulcer and anticoagulant activities in comparison with standard drugs. Hepatoprotective activity was assessed via serum biochemical parameters including aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma glutamyl transpeptidase (GGT), alkaline phosphatase (ALP) and total bilirubin. Tissue parameters such as non-protein sulfhydryl groups (NP-SH), malonaldehyde (MDA) and total protein (TP) were also measured. In addition to tissue parameters, nephroprotective effect was evaluated by measuring the serum levels of sodium, potassium, creatinine and urea. Histopathological study for both liver and kidney cells was also conducted. Antiulcer activity was explored by observing stomach lesions after treatment with ethanol. Whole blood clotting time (CT) was taken as a measure for the anticoagulant activity of the extract. Antioxidant activity of the total extract and fractions of the plant was measured using 2,2-diphenyl-1-picrylhydrazyl (DPPH) method and ascorbic acid as standard. PMID:25473335

    Investigations in 1965 located veins containing radioactive material in the Halaban Group on the east side of a granite pluton at Jabal Aja near Ha'il. Later study extended the known area of radioactivity to a total length of about 30 km. Mineralogic studies indicated that the samples were low in uranium and that the radioactivity was due principally to thorium in niobium-bearing minerals. Two samples were reexamined to identify the sources of radioactivity, but X-ray and alpha plate studies did not reveal the radioactive minerals, even though uranium mineralization was indicated by the alpha plates. Further sampling is suggested to isolate the sources of radioactivity. This study indicates that niobium occurrences are related to alkaline intrusives in many areas of western Saudi Arabia. These areas should be investigated for their possible niobium and rare earth contents; their uranium content is apparently too low to be of economic interest.

    Objectives To assess the use of an acellular collagen matrix (Pelvicol, Bard Medical, Covington, GA, USA), a successful agent for reconstructive surgery, for enhancing penile girth. Patients and methods Between June and December 2011, 18 patients (mean age 24 years, range 19–38) had their penis augmented with Pelvicol; the mean (range) penile circumference was 9.2 (7–13) cm before treatment. They were divided into two groups; the first (10 patients) had a Pelvicol sheet of 8 × 12 cm inserted through a V–Y suprapubic incision and wrapped around the shaft in a bilayer under the dartos fascia, but not covering the urethra, with division of the suspensory ligament. The second group of eight patients had the Pelvicol inserted through a subcoronal degloving incision and placed in one layer. The penile circumference was measured at 6 and 12 months after surgery. Patient satisfaction at 1 year after surgery was assessed as ‘poor’, ‘unsatisfied’, ‘moderately satisfied’, ‘highly satisfied’, or ‘excellent’. Results The mean (range) increase in girth (circumference) was 2.8 (2–3.2) cm in group 1 and 1.7 (1.2–2) cm in group 2. In group 1, two patients were highly satisfied, four moderately satisfied and four unsatisfied; in group 2, three were moderately satisfied and five unsatisfied. Complications were common in both groups, with five patients in group 1 and three in group 2 developing severe penile oedema and ischaemic shaft ulcers. Removal of the graft was required in two patients in each group. Conclusion This pilot study shows that Pelvicol is not an ideal option for enhancing penile girth, and the method of placement did not apparently influence the result. PMID:26558077

    This paper focuses on the use of the Yuri Nikolaevich DENISYUK holographic recording process to document, archive and display Saudi heritage. The goal of this research is to develop a technique of archiving heritage by using a high-tech holographic process to capture a three-dimensional presentation of ancient jewelry artifacts of the Saudi Heritage in particular. This study concentrates on five particular items of handmade authentic ancient metal jewelry from different parts of Saudi Arabia. When conducting this research experiments were conducted using both red-green sensitive plates sensitive to 633 nm and 532 nm respectively. Material thickness ranged between 1.5 and 3 millimeters were used, consequently in the dark room, varied chemicals for developing the holograms were employed. Red and green laser devices were also used with exposure times between 8 to 18 seconds of laser light dispersion through diffused surfaces in reflection holography. The outcome in each case was varied. The holograms captured the jewelry pieces with all the engravings and minute details, thus archiving the Saudi Heritage of that time. What makes holograms a revolutionary method for presenting valuable and/or ancient artifacts is the fact that they offer a more practical and convenient solution to travel around the world than displaying the originals items. Thus, museum visitors can enjoy and appreciate the precious artifacts otherwise unseen and lost without holography.

    Objectives: This cross-sectional study was conducted to explore the specialty chosen by the dental students for postgraduate studies and the future aspirations of students in a Saudi Arabia dental college. Materials and Methods: Of the total number of 120 questionnaires that were distributed, 107 subjects responded with selective responses and a response rate of 89%. A descriptive survey was conducted using one of the questionnaires among the students of dentistry at the dental college, Prince Sattam Bin Abdulaziz University, Al-Kharj among male students (men's college) for a period of 2 months. The data were analyzed using the statistical software program, predictive analytics software Statistics version 22.0 (SPSS Inc., Chicago, IL, USA). Results: A hundred and seven of the 120 students took part in the study. A passion for orthodontics (42.9%) was reported to be the most important factor that influenced the decision to pursue specialty training in orthodontics followed by intellectual stimulation/challenge (25%). The decision to pursue orthodontics was made by 32.1% of the respondents while in dental school; 35.7% took the decision after completing dental school during private practice and 14.3% during a dental residency, whereas 3.6% had already decided before initiating their dental school studies. Working in a private practice environment was preferred by 11 residents (39.3%). Only four residents indicated that they would most likely be practicing in an academic setting while 10 were undecided. Conclusions: The zest for nonclinical specialties is less among students at Prince Sattam Bin Abdulaziz University's dental college, Saudi Arabia. PMID:27195220

    Chromatographic investigation of fruits obtained from Citrullus colocynthis, growing in Saudi Arabia, led to isolation of two compounds; Cucurbitacin E glucoside (Cu E, 1), and Cucurbitacin I glucoside (Cu I, 2). The chemical structures of 1 and 2, were elucidated by spectroscopic analyses include; 1D ((1)H and (13)C) and 2D (COSY, HMQC and HMBC) NMR and ESI-MS spectroscopy. The in vitro cytotoxic activity against hepatoma cell line (HepG2) and mice-bearing tumor of Ehrlich's ascites carcinoma (EAC) of the compounds were estimated. Both compounds had potent inhibitory activity on HepG2 with IC(50) 3.5 and 2.8 nmol/mL, respectively. In addition to these activities, the in vivo study employing EAC, showed the capability of both compounds to prolong the survival time, life span and normalize the biochemical parameters of the infected mice with EAC.

  5. Can natural selection favour altruism between species?

    Wyatt, G A K; West, S A; Gardner, A

    2013-09-01

    Darwin suggested that the discovery of altruism between species would annihilate his theory of natural selection. However, it has not been formally shown whether between-species altruism can evolve by natural selection, or why this could never happen. Here, we develop a spatial population genetic model of two interacting species, showing that indiscriminate between species helping can be favoured by natural selection. We then ask if this helping behaviour constitutes altruism between species, using a linear-regression analysis to separate the total action of natural selection into its direct and indirect (kin selected) components. We show that our model can be interpreted in two ways, as either altruism within species, or altruism between species. This ambiguity arises depending on whether or not we treat genes in the other species as predictors of an individual's fitness, which is equivalent to treating these individuals as agents (actors or recipients). Our formal analysis, which focuses upon evolutionary dynamics rather than agents and their agendas, cannot resolve which is the better approach. Nonetheless, because a within-species altruism interpretation is always possible, our analysis supports Darwin's suggestion that natural selection does not favour traits that provide benefits exclusively to individuals of other species.

    A preliminary study was carried out on the insect fauna of Al-Baha Province, south-western part of Saudi Arabia. A total number of 582 species and subspecies (few identified only to the genus level) belonging to 129 families and representing 17 orders were recorded. Two of these species are described as new, namely: Monomorium sarawatensis Sharaf & Aldawood, sp. n. [Formicidae, Hymenoptera] and Anthrax alruqibi El-Hawagry sp. n. [Bombyliidae, Diptera]. Another eight species are recorded for the first time in Saudi Arabia, namely: Xiphoceriana arabica (Uvarov, 1922) [Pamphagidae, Orthoptera], Pyrgomorpha conica (Olivier, 1791) [Pyrgomorphidae, Orthoptera], Catopsilia florella (Fabricius, 1775) [Pieridae, Lepidoptera], Anthrax chionanthrax (Bezzi, 1926) [Bombyliidae, Diptera], Spogostylum near tripunctatum Pallas in Wiedemann, 1818 [Bombyliidae, Diptera], Cononedys dichromatopa (Bezzi, 1925) [Bombyliidae, Diptera], Mydas sp. [Mydidae, Diptera], and Hippobosca equina Linnaeus, 1758 [Hippoboscidae, Diptera]. Al-Baha Province is divided by huge and steep Rocky Mountains into two main sectors, a lowland coastal plain at the west, known as "Tihama", and a mountainous area with an elevation of 1500 to 2450 m above sea level at the east, known as "Al-Sarat or Al-Sarah" which form a part of Al-Sarawat Mountains range. Insect species richness in the two sectors (Tihama and Al-Sarah) was compared, and the results showed that each of the two sectors of Al-Baha Province has a unique insect community. The study generally concluded that the insect faunal composition in Al-Baha Province has an Afrotropical flavor, with the Afrotropical elements predominant, and a closer affiliation to the Afrotropical region than to the Palearctic region or the Eremic zone. Consequently, we tend to agree with those biogeographers who consider that parts of the Arabian Peninsula, including Al-Baha Province, should be included in the Afrotropical region rather than in the Palaearctic region or the

    Background There is a paucity of data on the national prevalence of diabetes and prediabetes among youth. The Saudi Abnormal Glucose Metabolism and Diabetes Impact Study (SAUDI-DM) was used to assess the prevalence of type 1 and type 2 diabetes as well as impaired fasting glucose (IFG) among children and adolescents. Methods Sociodemographic, anthropometric and clinical data were collected through a nationwide household randomly selected 23 523 children and adolescents aged ≤18 years. Known participants with diabetes were classified according to their diabetes type, while participants without diabetes were subjected to fasting plasma glucose assessment and patients with diabetes were identified using the American Diabetes Association (ADA) criteria. All the studied participants were tested for lipid parameters. Multivariate logistic regression analysis was used to assess different risk factors. Results The overall prevalence of diabetes was 10.84%, of which 0.45% were known type 1 and type 2 patients with diabetes and 10.39% were either newly identified cases of diabetes (4.27%) or IFG (6.12%) with more than 90% of the participants with diabetes being unaware of their disease. The prevalence of known type 1 and type 2 diabetes as well as the newly identified cases was higher than what has been reported internationally. Age, male gender, obesity, urban residency, high family income and presence of dyslipidaemia were found to be significant risk factors for diabetes and IFG. Conclusions Diabetes and IFG are highly prevalent in this society with the majority of the patients being unaware of their disease, which warrants urgent adoption of early detection, treatment and prevention programmes.

    Background Medical education in Saudi Arabia is facing multiple challenges, including the rapid increase in the number of medical schools over a short period of time, the influx of foreign medical graduates to work in Saudi Arabia, the award of scholarships to hundreds of students to study medicine in various countries, and the absence of published national guidelines for minimal acceptable competencies of a medical graduate. Discussion We are arguing for the need for a Saudi national medical licensing examination that consists of two parts: Part I (Written) which tests the basic science and clinical knowledge and Part II (Objective Structured Clinical Examination) which tests the clinical skills and attitudes. We propose this examination to be mandated as a licensure requirement for practicing medicine in Saudi Arabia. Conclusion The driving and hindering forces as well as the strengths and weaknesses of implementing the licensing examination are discussed in details in this debate. PMID:19032779

    Globalisation is often thought to advocate for a single set of beliefs and customs and for a rejection of the need to protect regional cultures and traditions. In the aftermath of 9/11, the rift between Western and Arab cultures has deepened, and there is a patent need for cultural bridges to be built. The government of Saudi Arabia has, by increasing funding for higher education through grants and scholarships, enabled Saudi students to study at overseas universities. A number of non-Saudi students are also enrolled at Saudi Arabian universities. After a brief introduction to the cultural and educational history of the Arab region and Saudi identity, this article turns to contemporary higher education in Saudi Arabia. It introduces the King Abdullah Scholarship Programme and then goes on to present detailed enrolment data for 2006-2009, demonstrating trends and policy changes and identifying patterns in student mobility.

    Background: Sedentary life style and consequent obesity prevail in both developed and developing nations; gender- and age-independently. Physical inactivity in a population in a life style transition–like Saudi Arabia–causes metabolic syndrome with its immediate and long-term complications. Healthcare workers are in a better position for role modeling and counseling of appropriate health behaviors. Personal physical activity and body built among physicians influences to some degree their exercise counseling. Realizing such principle necessitates gauging the extent of physical activity among physicians and assessing the likelihood of counseling the patients on physical activities. Methods: A cross-sectional study enrolled primary health care physicians (PHCPs) from primary health care centers and general hospitals of two cities (Sakaka and Dumat Al-Jandal) of Aljouf region, Saudi Arabia. Both genders were included. English version of step-wise questionnaire of World Health Organization was used for data collection. Results: The response rate was 64.2%. 65.2% of respondent PHCPs were doing moderate to vigorous physical exercise and 34.8% of them were physically inactive. Majority of physically inactive PHCPs had intention to increase their physical activity. Neither gender, nationality nor city-wise significant differences were recorded. However, physically active PHCPs significantly impart advice and role modeling on physical activity to their patients compared to physically inactive PHCPs (p<0.01). Conclusion: Most PHCPs in Sakaka and Dumat Al-Jandal cities were physically active and were able to impart the healthy behavior counseling to their patients. A strong intention prevailed to increase physical activity among physically inactive Primary Health care Physicians (PHCPs). PMID:26543420

    Western countries are experiencing a nursing shortage which will impact on future nurse manpower supply in Saudi Arabia because the Kingdom is dependent on expatriate nurses. The young people of Saudi Arabia are the Kingdom's most valuable resources but are reluctant to enter nursing. Therefore, a random survey was administered to 1,131 secondary and university students to determine attitudes and general knowledge of Saudi nationals toward the health care system, perceived role of the nurse and recommendations for improving Saudization of the nursing profession. The majority of those surveyed preferred hospitalization within the Kingdom with Saudi nationals delivering the nursing care rather than expatriates. The nurse was perceived as being a caring person who was responsible for giving more than custodial care. Moreover, the role of the nurse was perceived as an extension of the physician with little or no role in disease detection and prevention. The low image and status of nursing, traditional and social values were identified as major inhibiting factors that affect the Saudi nationals' reluctance to enter nursing. Increasing financial rewards, utilizing the media and segregation of hospitals into male and female were the most frequently cited recommendations to promote Saudization of nursing. Data from this study provided insight into the current perception of nursing as a potential career for Saudi nationals and could provide direction for future concerns in the development of nursing in the Kingdom.

    STUDY OBJECTIVE--The study aimed to investigate some aspects of breast feeding, namely-lactation amenorrhea, the average interval between pregnancies, and the extent of knowledge that an average Saudi woman has about breast feeding. DESIGN--This was a cross sectional study in which a pretested questionnaire was used to collect the information. SETTING--The study was conducted in the Taif area between January and April of 1990. Seventy nine primary health care centres participated. PARTICIPANTS--Altogether 1019 of 2400 women contacted who agreed to participate and met the criteria were studied. Eligible subjects were defined as Saudi women, between 16 and 40 years old, who came with their infants for vaccination, and had delivered between one week and 12 months previously. Each mother had at least one other child. MEASUREMENT AND MAIN RESULT--At birth, the percentage of infants who were initially breast fed was 98% but within three days of delivery over two thirds (68.9%) of the mothers gave other supplementary liquids to their infants. At the time of interview more than half (55.1%) of mothers had lactation amenorrhea. The mean (SD) lactation amenorrhea period and birth interval were 5.95 (5) and 26.8 (14.1) months, respectively. Mothers obtained information on breast feeding mainly from their doctors and television. Within families, husbands had the primary role in encouraging their wives to breast feed, followed by the mother and then by the mother in law. It was found that a high percentage (94.2%) of women had breast fed their previous child. CONCLUSION--The lack of adequate information on breast feeding and the short interval between births are local problems which should be considered by the health authorities. PMID:8051529

    Background: Vitiligo has a devastating psychosocial effect. The cultural traditions of Saudi society are quite different compared with the western world. Hence, a quality of life study using a different questionnaire suitable to the cultural traditions of the society is necessary to measure qualify of life in vitiligo patients. Objective: This study was conducted to assess the quality of life (QOL) in Saudi vitiligo patients and their family. Materials and Methods: A prospective cross-sectional study at National Center for Vitiligo and Psoriasis, Saudi Arabia. A validated Arabic questionnaire of 41 questions was developed and utilized specifically for this study. Arabic language instrument was distributed to 260 vitiligo patients. Scores were compared in relation to demographic, clinical, and social variables in 4 dimensions of scale (relationship with colleagues, family relationship, social relationship, and self respect). Results: Overall score QOL was 17.1. Mean score for males was 11.1, whereas that for females was 23.9 (P < 0.05). Females scored significantly higher in all the 4 dimensions. Patients with exposed disease lesions scored significantly higher than those with unexposed lesions 5 vs 3.4 (P < 0.05). Conclusion: The overall score of QOL in vitiligo is relatively high, indicating a negative impact of the disease on QOL. QOL in women is significantly more affected than in men. PMID:21572679

    This paper describes perceptions of familiarity with symptoms and beliefs about illnesses based on interviews with 50 Saudi women. The sample was young, with 82% under the age of 40, and not well educated by Western standards, with one-third being illiterate and 80% having no more than a primary school education. More than half lived in households of six or more. Although there was greater awareness of germs as causative factors in illness than previous studies in Saudi Arabia had demonstrated, beliefs in multiple causes, including religious beliefs about disease causation, persisted. There was an apparent lack of understanding of specific causes of various illnesses or of the rationale for preventive measures. This lack of understanding may be related to the low education levels and/or deeply ingrained cultural beliefs. PMID:1475998

    Riyadh, the national capital of Saudi Arabia, is shown in 1972, 1990 and 2000. Its population grew in these years from about a half million to more than two million. Saudi Arabia experienced urbanization later than many other countries; in the early 1970s its urban-rural ratio was still about 1:3. By 1990 that had reversed to about 3:1. The city grew through in-migration from rural areas, and from decreases in the death rate while birthrates remained high. The 1972 image is a Landsat MSS scene; the 1990 image is a Landsat Thematic Mapper scene; and the 2000 image is an ASTER scene. All three images cover an area of about 27 x 34 km. The image is centered at 24.6 degrees north latitude, 46.6 degrees east longitude.

    Background: Previous studies have demonstrated an association between obesity and asthma, but there remains considerable uncertainty about whether this reflects an underlying causal relationship. Aims: To investigate the association between obesity and asthma in pre-pubertal children and to investigate the roles of airway obstruction and atopy as possible causal mechanisms. Methods: We conducted an age- and sex-matched case–control study of 1,264 6- to 8-year-old schoolchildren with and without asthma recruited from 37 randomly selected schools in Madinah, Saudi Arabia. The body mass index (BMI), waist circumference and skin fold thickness of the 632 children with asthma were compared with those of the 632 control children without asthma. Associations between obesity and asthma, adjusted for other potential risk factors, were assessed separately in boys and girls using conditional logistic regression analysis. The possible mediating roles of atopy and airway obstruction were studied by investigating the impact of incorporating data on sensitisation to common aeroallergens and measurements of lung function. Results: BMI was associated with asthma in boys (odds ratio (OR)=1.14, 95% confidence interval (CI), 1.08–1.20; adjusted OR=1.11, 95% CI, 1.03–1.19) and girls (OR=1.37, 95% CI, 1.26–1.50; adjusted OR=1.38, 95% CI, 1.23–1.56). Adjusting for forced expiratory volume in 1 s had a negligible impact on these associations, but these were attenuated following adjustment for allergic sensitisation, particularly in girls (girls: OR=1.25; 95% CI, 0.96–1.60; boys: OR=1.09, 95% CI, 0.99–1.19). Conclusions: BMI is associated with asthma in pre-pubertal Saudi boys and girls; this effect does not appear to be mediated through respiratory obstruction, but in girls this may at least partially be mediated through increased risk of allergic sensitisation.

    2014-01-01

    The media-fuelled obsession with beauty in modern society has led more women to seek elective cosmetic procedures to meet the portrayed ideals of beauty in different cultures. This study gives insights into incentives and desires to undergo cosmetic procedures in a conservative society with strict religious practices where women are veiled. Questionnaire data were obtained from 509 Saudi women who responded to a survey distributed randomly to a sample of Saudi women aged 17 to 72 years. At least 1 elective cosmetic procedure was performed in 42% of the women, of whom 77.8% wore a veil. Another 33% considered having a procedure. The motives for seeking a cosmetic procedure were to improve self-esteem in 83.7%, attract a husband in 63.3%, or prevent a husband from seeking another wife in 36.2%. The decision to seek a procedure was affected by the media, with high peer influence. Motivation for elective cosmetic procedures in Saudi women is influenced by a combination of emotional and cultural factors, level of education, marital status, and religious beliefs. The veil is not an impediment for seeking such procedures. The limitation of the study was missing data analysis as some items in the questionnaire were completed inaccurately or left unanswered.

  4. Essays on oil and business cycles in Saudi Arabia

    NASA Astrophysics Data System (ADS)

    Aba Alkhail, Bandar A.

    This dissertation consists of three chapters. Chapter one presents a theoretical model using a dynamic stochastic general equilibrium (DSGE) approach to investigate the role of world oil prices in explaining the business cycle in Saudi Arabia. This model incorporates both productivity and oil revenue shocks. The results indicate that productivity shocks are relatively more important to business cycles than oil shocks. However, this model has some unfavorable features that are associated with both investment and labor hours. The second chapter presents a modified theoretical model using DSGE approach to examine the role of world oil prices versus productivity shocks in explaining the business cycles in Saudi Arabia. To overcome the unfavorable features of the baseline model, the alternative model adds friction to the model by incorporating investment portfolio adjustment cost. Thus, the alternative model produces similar dynamics to that of the baseline model but the unfavorable characteristics are eliminated. Also, this chapter conducts sensitivity analysis. The objective of the third chapter is to empirically investigate how real world oil price and productivity shocks affect output, consumption, investment, labor hours, and trade balance/output ratio for Saudi Arabia. This chapter complements the theoretical model of the previous chapters. In addition, this study builds a foundation for future studies in examining the impact of real world oil price shocks on the economies of key trade partners of Saudi Arabia. The results of the third chapter show that productivity shocks matter more for macroeconomic fluctuations than oil shocks for the Saudis' primary trade partners. Therefore, fears of oil importing countries appear to be overstated. As a whole, this research is important for the following reasons. First, the empirical model is consistent with the predictions of our theoretical model in that productivity is a driving force of business cycles in Saudi Arabia

    Many studies worldwide have demonstrated the negative impact of an unhealthy built environment on citizens. In the case of diabetes, studies have concentrated on the environmental impact and accessibility issues of a place i.e. the home and neighborhood, whereas few studies have addressed the comfort of the type and spatial arrangement of a household and linked it with the prevalence of diabetes. Also, little research has tackled the place’s impact on diabetic patients and their views concerning their environments. This paper demonstrates the outcomes of survey that was carried out on diabetic individuals who usually visit the King Fahd teaching hospital of the University of Dammam, Al-Khober, the Kingdom of Saudi Arabia (KSA). The patients were surveyed and physically examined. The present researchers found significant links between patients’ diabetes symptoms such as reported paresthesia and blurred vision, and medical investigations results such as lipid profile, blood glucose and blood pressure with the environmental conditions of their homes and neighborhoods. The paper shows that the prevalence of the disease is not only caused by an unhealthy lifestyle but also by an unhealthy built environment. Moreover, it illustrates that unhealthy built environment promotes unhealthy life styles. It makes recommendations on how to improve the built environment in the KSA to be healthier for all citizens including the diabetic patients. PMID:24999135

  14. Study of Seismogenic Crust In The Eastern Province of Saudi Arabia And Its Relation To The Seismicity of The Ghawar Fields

    The Rayn Anticlines (RA) developed in the Eastern Province of Saudi Arabia are truncated by the Abu-Jifan Fault (AJF) to their southeast and by the Wadi-Batin Fault (WBF) to the northwest. This set of anticlines is comprised of six sub-parallel super-giant anticlines, including the Ghawar Anticline (GA). Here we firstly present a revised seismicity map for the Eastern Province on the basis of ';Reviewed ISC Earthquake Catalogue' for the period 1970-2010 that shows the Eastern Province crust is seismogenic down to about 45 km depth while its surface width is 220 km (what is seven times wider than the width of GA). The Saudi Geological Survey (SGS) Earthquake Network Catalogue for Eastern Province shows that characteristic magnitude completeness (Mc), based on the assumption of self-similarity, have detected all local earthquakes above the cut-off magnitude ≥ 2.7. SGS catalogue events demonstrate that the GA is seismically intensely active where 826 events have originated during the period of 2005-10, of maximum magnitude ML 4.24. These events came almost in equal proportions from the Uthmaniyah-Hawaiyah and Haradh production divisions belonging to the central and southern Ghawar oil/gas Fields, where, the seismic zones orient in NE and NW directions respectively. Focal-depth distribution of events along the strike direction of seismic zones follows the ';En Nala axis' in GA and broadly defines an inverted triangular zone extending to crustal depths. Seismic activity below both the production divisions is supposedly triggered by hydrocarbon fluid-extraction activity; although, their root cause is probably due to regional compressive stress operative across RA. Triggered seismicity locally shows better correlation to mutually opposite reverse faults oriented NW and NE transgressing the Haradh and Uthmaniyah-Hawaiyah production divisions under the influence of regional compressive stress oriented N40°E. Some support to this inference comes from mapped surface faults

    OBJECTIVE: Assessing the knowledge and awareness of the Saudi society about bronchial asthma in children. METHODS: Structured questionnaires were randomly distributed to 1039 Saudi Arabians in May 2014 at Jeddah, Riyadh, and Dammam. RESULTS: The awareness of bronchial asthma questions showed that 67% of total sample thought that it could be a fatal disease, and only 13.2% thought that there is a difference between bronchial asthma and chest allergies in children. 86.1% thought that the symptoms of bronchial asthma include dyspnea and nocturnal cough, and 45.7% thought that fever, a runny nose and throat inflammation are not symptoms. 60.2% thought that infectious respiratory diseases may increase bronchial asthma progression. In addition, 40% thought that the use of antibiotics doesn’t help in diminishing bronchial asthma complications, and some thought that the patient can stop medication after an acute asthma attack. 34.1% thought that inhaled medication for asthma doesn’t cause addiction. Very highly significant results are shown between bronchial asthma knowledge and age, the level of education, marital status, and if the individual knows a person who suffers from bronchial asthma (P < 0.001). There are positive correlations between bronchial asthma knowledge and age, marital status, and level of education (r = 0.152, 0.150, 0.197), respectively. CONCLUSION: The study demonstrated that bronchial asthma knowledge in the Saudi Arabian population is insufficient, and efforts should be carried out to spread bronchial asthma management.

    One of the expected effects of the global warming is changing coastal habitats by accelerating the rate of sea level rise. Coastal habitats support large number of marine and wetland species including shorebirds (plovers, sandpipers and allies). In this study, we investigate how coastal habitats may be impacted by sea level rise in the Farasan Islands, Kingdom of Saudi Arabia. We use Kentish plover Charadrius alexandrinus - a common coastal breeding shorebird - as an ecological model species to predict the influence of sea level rise. We found that any rise of sea level is likely to inundate 11% of Kentish plover nests. In addition, 5% of the coastal areas of Farasan Islands, which support 26% of Kentish plover nests, will be flooded, if sea level rises by one metre. Our results are constrained by the availability of data on both elevation and bird populations. Therefore, we recommend follow-up studies to model the impacts of sea level rise using different elevation scenarios, and the establishment of a monitoring programme for breeding shorebirds and seabirds in Farasan Islands to assess the impact of climate change on their populations.

    Summary The Middle East respiratory syndrome coronavirus (MERS-CoV) was first described in September 2012 and to date 86 deaths from a total of 206 cases of MERS-CoV infection have been reported to the WHO. Camels have been implicated as the reservoir of MERS-CoV, but the exact source and mode of transmission for most patients remain unknown. During a 3 month period, June to August 2013, there were 12 positive MERS-CoV cases reported from the Hafr Al-Batin region district in the north east region of the Kingdom of Saudi Arabia. In addition to the different regional camel festivals in neighboring countries, Hafr Al-Batin has the biggest camel market in the entire Kingdom and hosts an annual camel festival. Thus, we conducted a detailed epidemiological, clinical and genomic study to ascertain common exposure and transmission patterns of all cases of MERS-CoV reported from Hafr Al-Batin. Analysis of previously reported genetic data indicated that at least two of the infected contacts could not have been directly infected from the index patient and alternate source should be considered. While camels appear as the likely source, other sources have not been ruled out. More detailed case control studies with detailed case histories, epidemiological information and genomic analysis are being conducted to delineate the missing pieces in the transmission dynamics of MERS-CoV outbreak.

    The aim of this study was to use geographical information systems to demonstrate the Dengue fever (DF) risk on a monthly basis in Jeddah, Saudi Arabia with the purpose to provide documentation serving to improve surveillance and monitor the Aedes aegypti mosquito vector. Getis-Ord Gi* statistics and a frequency index covering a five-year period (2006-2010) were used to map DF and model the risk spatio-temporally. The results show that monthly hotspots were mainly concentrated in central Jeddah districts and that the pattern changes considerably with time. For example, on a yearly basis, for the month of January, the Burman district was identified as a low risk area in 2006, a high-risk area in 2007, medium risk in 2008, very low risk in 2009 and low risk in 2010. The results demonstrate that it would be useful to follow the monthly DF pattern, based on the average weekly frequency, as this can facilitate the allocation of resources for the treatment of the disease, preventing its prevalence and monitoring its vector.

    Objectives: To examine relationship between the quality of marital relationship and anxiety among women with breast cancer (BC) in the Kingdom of Saudi Arabia (KSA). Methods: This cross-sectional study recruited a consecutive series of 49 married women with BC seen in the Al-Amoudi Breast Cancer Center of Excellence at King Abdulaziz University, Jeddah, KSA in early 2013. Participants completed the Hospital Anxiety and Depression Scale, Spouse Perception Scale, and Quality of Marriage Index forms, and answered questions on demographic and cancer characteristics. Results: Anxiety symptoms indicating “possible” anxiety disorder were present in 10.4% and “probable” anxiety disorder in 14.6% (25% total). No significant relationship was found between the quality of marital relationship and anxiety symptoms (B=-0.04, standard error=0.05, t=-0.81, p=0.42). Anxiety was primarily driven by low education, poor socioeconomic status, and young age. Conclusion: Anxiety symptoms are prevalent among married women with BC seen in a university-based clinic in the KSA. Further research is needed to determine whether a diagnosis of BC adversely affects marital relationship, and whether this is the cause for anxiety in these women. PMID:26446326

  1. A study on the social structure and dispersal patterns of hamadryas baboons living in a commensal group at Taif, Saudi Arabia.

    Three levels of hamadryas social structure--the one male unit (OMU), the band, and the troop--have been observed at all sites studied, but a fourth--the clan--has been observed at only one site, Erer-Gota, Ethiopia, during a longitudinal check of the dispersion of identified individuals. The clan is important since it appears to provide the basis for male philopatry, although comparative data is needed from other sites to confirm this. We studied a huge commensal group of hamadryas baboons (over 600 animals) in Saudi Arabia. We put ear tags on baboons between 1998 and 2004 and analyzed social structure, relying on the interactions of these tagged animals by focusing especially on their dispersal patterns from OMUs. OMU membership tended to be looser than that of the Ethiopian hamadryas. Females tended to shift between OMUs on an individual basis in our study group, whereas the collapse of an OMU was a major occasion of adult female transfer in Ethiopia. We found neither stable bands (a "band" in our study group was defined as a regional assemblage of OMUs) nor clans that lasted for several years. Some OMUs moved and transferred into neighboring areas over both the short and long term. Further, some post-adolescent males appeared to move out of the study area. The ratio of adult females in an OMU in our study group was larger than for any other documented study site, and this may be the reason for enhanced female transfer between OMUs. A large proportion of the adolescent females showed no clear membership to OMUs, and no "initial units" (commonly observed in Ethiopia) were discernible. The ease with which young males acquired adult females at the study site must have disrupted the formation of a clan, a "male-bonded society." PMID:17415621

The common clinical presentation of B19 virus (B19V) infection is erythema infectiosum, arthropathy, aplastic crisis, and fetal infection. Infection in seronegative pregnant women can lead to fetal hydrops. Objectives: To determine the seroprevalence of immunoglobulin G (IgG) to erythrovirus B19 in Saudi pregnant women in the cities of Makkah and Jeddah in Saudi Arabia. Materials and Methods: A total of 364 blood (serum) samples were tested for erythrovirus B19-specific-IgG antibody in Saudi pregnant women in the cities of Makkah and Jeddah in Saudi Arabia. Results: Erythrovirus B19-specific-IgG antibodies were detected in 182/364 (50%) of Saudi pregnant women of different age groups. Conclusion: This study indicated that B19V is clearly circulating in the community in a way that is similar to what is found in most nontemperate countries. PMID:27186157

    We studied knowledge of nutritional needs during pregnancy and lactation in 150 pregnant Saudi women at three primary health care centers in Riyadh, Saudi Arabia. We used an interview schedule to collect data regarding the women's knowledge and to determine the effects of certain independent variables on the knowledge scores. Green et al.'s (1980) PRECEDE model provided the theoretical framework for the study. Descriptive statistics, t test, and chi-square methods were used to analyze the data. The majority of the women had poor nutrition knowledge scores, with no significant differences among the three centers. A positive relationship was found between knowledge score and educational level. Negative relationships were found between knowledge score and number of pregnancies, number of deliveries, and number of living children. The findings have several implications for efforts to improve the health status of women in Saudi Arabia. PMID:8002417

  4. Frequency and risk factors of musculoskeletal pain in nurses at a tertiary centre in Jeddah, Saudi Arabia: a cross sectional study

    2014-01-01

    Background Musculoskeletal complaints are an important occupational problem; nevertheless, few studies have targeted nurses in Saudi Arabia. The aim of this study was to determine the frequency and risk factors of work-related musculoskeletal disorders (WMSDs) among nursing personnel at a tertiary centre in Jeddah. Methods A comparative cross-sectional study was performed in which full-time registered nurses from four different departments (n = 200) were selected for analysis between September 1, 2011 and February 29, 2012. Musculoskeletal symptoms over the past year were assessed using the Nordic Standardised Musculoskeletal Questionnaire. In addition to demographic questions, the researcher evaluated employment history, physical risk factors at work, and general health status. Results In this study, approximately 85% of the nurses reported experiencing at least one musculoskeletal symptom. Musculoskeletal symptoms occurred most commonly in the lower back (65.7%), ankles and feet (41.5%), and shoulders (29%). Prolonged working hours and being underweight were significantly associated with the development of these symptoms (OR 3.66, 95% CI 1.24-10.79, P = 0.018, and OR 2.66, 95% CI 1.37-5.93, P = 0.004, respectively). Working in the surgical department was a greater risk factor for low back pain compared with working in other departments. Conclusions WMSDs are common among our nurses, and back pain is the most common symptom. As prolonged working hours and being underweight were factors that contributed most to WMSDs, decreasing shift durations or offering nutrition educational programmes may be suitable solutions. However, further studies are required to examine the best modality for decreasing the occurrence of WMSDs. PMID:24460669

    2006-01-01

    This article seeks to examine the impact of technology importation on occupational health and safety in both Saudi Arabian and U.S. oil refining industries. Technologies imported to the Saudi oil industry take two forms: hardware (sophisticated equipment to run oil facilities) and software (policies and regulations pertaining to workers' health and safety, and employment rights installed by Aramco's founding multinational companies). This study utilizes qualitative, historically oriented, cross-national case studies to compare and assess workers' health, safety, and rights in Saudi Aramco with its U.S. counterpart, Motiva Enterprises. Two facilities were chosen to conduct field research: the Saudi Aramco oil refinery at Jeddah and Motiva's refinery at Port Arthur, Texas. The Jeddah refinery is fully owned by Saudi Aramco, thus, representing Aramco's health and safety policies and regulations. The Port Arthur refinery serves as a reference case study for U.S. oil refining facilities. The aspects of occupational health and safety in Saudi Aramco--ExxonMobil's joint ventures SAMREF and LUBREF--also are discussed to examine workers' health policies in both companies. The American oil industry made a significant contribution in establishing the Saudi oil industry, with the cooperation of the Saudi government. Despite having outstanding employment benefits schemes in Saudi Aramco, the presence of an organized work force better serves employee participation in Motiva than in Aramco. Safety systems such as Process Safety Management (PSM)--applied in Motiva--partially exist in Aramco to operate hardware technologies safely. Motiva training systems are better through PACE's Triangle of Prevention (TOP). Both companies follow the same pattern of handling occupational injuries and diseases; however, Saudi government agencies (GOSI) are responsible for compensating and treating injured workers. Saudi workers expressed conditional support for the worker committee program

    Organ transplantation started in the Kingdom of Saudi Arabia (KSA) in 1979 with a kidney transplanted from a live donor. The Saudi Center for Organ Transplantation has been established in 1985 as a governmental agency that supervises all national transplant activities in the KSA. Organ transplantation in the KSA has made great strides since 1985. Saudi Center for Organ Transplantation is playing a central role in all aspects of transplantation including education on all levels, allocation, coordination and procurement. A new initiative has started an ambitious program in 2014 to improve the identification and reporting of organ donors aiming at an annual rate of 15 donors per million populations within 3 years in the KSA.

    Dinosaur remains from the Arabian subcontinent are exceedingly rare, and those that have been documented manifest indeterminate affinities. Consequently the discovery of a small, but diagnostic, accumulation of elements from Campanian-Maastrichtian (~ 75 Ma) deposits in northwestern Saudi Arabia is significant because it constitutes the first taxonomically identifiable dinosaur material described from the Arabian Peninsula. The fossils include a series of possible lithostrotian titanosaur caudal vertebrae, and some isolated theropod marginal teeth that share unique character states and metric parameters (analyzed using multivariate statistical methods) with derived abelisaurids - this is the first justifiable example of a non-avian carnivorous dinosaur clade from Arabia. The recognition of titanosaurians and abelisaurids from Saudi Arabia extends the palaeogeographical range of these groups along the entire northern Gondwanan margin during the latest Cretaceous. Moreover, given the extreme paucity of coeval occurrences elsewhere, the Saudi Arabian fossils provide a tantalizing glimpse into dinosaurian assemblage diversity within the region. PMID:24386326

    Dinosaur remains from the Arabian subcontinent are exceedingly rare, and those that have been documented manifest indeterminate affinities. Consequently the discovery of a small, but diagnostic, accumulation of elements from Campanian-Maastrichtian (∼75 Ma) deposits in northwestern Saudi Arabia is significant because it constitutes the first taxonomically identifiable dinosaur material described from the Arabian Peninsula.

    2014-01-01

    Associations between biological traits of animals and climate are well documented by physiological and local-scale studies. However, whether an ecophysiological phenomenon can affect large-scale biogeographical patterns of insects is largely unknown. Insects absorb energy from the sun to become mobile, and their colouration varies depending on the prevailing climate where they live. Here we show, using data of 473 European butterfly and dragonfly species, that dark-coloured insect species are favoured in cooler climates and light-coloured species in warmer climates. By comparing distribution maps of dragonflies from 1988 and 2006, we provide support for a mechanistic link between climate, functional traits and species that affects geographical distributions even at continental scales. Our results constitute a foundation for better forecasting the effect of climate change on many insect groups. PMID:24866819

    Efforts to quantify runoff and sediments yields and to assess the factors controlling their spatial and temporal distribution are often hindered by the paucity of appropriate field data. In this study, we developed and applied an integrated cost-effective approach that takes advantages of the readily available remote sensing datasets to quantify the runoff and sediments yields of the Red Sea costal watersheds, Saudi Arabia. The Soil Water Assessment Tool (SWAT) model was implemented to determine annual runoff and sediment yields, spatially delineate the factors controlling their distribution, and predict their response to climate change. SWAT is a public-domain, Geographic Information System (GIS)-based, spatially-distributed, dynamic model that can simulate watershed scale hydrology and water quality processes. The landuse-landcover GIS layer for the selected watersheds was downloaded and manually updated from the Global Land Cover 2000 (GLC 2000) datasets. Soil data was downloaded from the Harmonized World Soil Database (HWSD) and refined from 1:250,000 scale geologic maps. A 90m digital elevation model (DEM) extracted from Shuttle Radar Topography Mission (STRM) data was used to characterize the watershed boundaries in SWAT. Weather data for model simulations was downloaded from the global weather data for SWAT. Model simulations were performed for the period from 1979 to 2010 for 10 watersheds ranging in areas from 5×103 km2 to 107×103 km2. Preliminary results show an average annual precipitation, runoff, and sediments yields of 78.1 mm (8.3 ×109 m3), 24.5 mm (2.6 ×109 m3), 0.1 ton/ha, respectively for Wadi El Hamd watershed (area: 107×103 km2). Model calibration is being performed by comparing simulated stream flow discharge and sediment yields against measured values. The response of the runoff and sediments yields to the climate change is being estimated using predictions from Community Climate System Model (CCSM) outputs.

    Objectives: To estimate age at menarche and to assess trends in menarcheal age among Saudi women. Methods: A prospective longitudinal study was conducted among healthy prepubertal female school children and adolescents from September 2006 to July 2012 in Riyadh, Kingdom of Saudi Arabia. Study participants were invited from diverse socioeconomic backgrounds. Tanner stage, height, weight, body mass index, and socioeconomic parameters including parent’s level of education were collected. Age at menarche was compared with maternal age at menarche. Results: The study included 265 girls and mothers. Mean±standard deviation (SD) age at menarche for girls was 13.08 ± 1.1 years, and their distribution category across the ≤10 years was 4 (1.5%), 11-14 years was 239 (90.2%), and ≥15 years was 22 (8.3%) girls. Anthropometric measurements, mother’s level of education, and family income were not statistically significant determining factors associated with age at menarche. Mean ± SD age at menarche for mothers was 13.67 ± 1.4 years, and their distribution category across the ≤10 years was 7 (2.6%), 11-14 years was 172 (64.9%), and ≥15 years was 86 (32.5%). Girls attained menarche at younger age compared with their mothers (p<0.0001). A downward secular trend in age of menarche was observed (Cuzick test for trend = 0.049). Conclusion: Saudi girls attain menarcheal age earlier than their mothers, reflecting a downward secular trend in menarcheal age. PMID:26593166

    Investigations on indoor airborne allergens in Saudi Arabia were performed by mold cultures and dust analyses by counter-current immunoelectrophoresis. Twenty fungal genera were isolated, with Aspergillus as the most often encountered. Most of the dust-bound fungi found are ubiquitous and common. Antibodies against Dermatophagoides pteronyssinus, cat- cow- and rat dander, and Cynodon dactylon pollen were used in the dust analyses. Animal antigens were found in five of the ten dust samples. House dust mites were extraordinarily rare. Pollen of Cynodon dactylon (Bermuda grass) was present in nearly all the samples, and in a concurrent clinical study this antigen was found to be the most common cause of perennial rhinitis.

    [Purpose] There is a dearth of studies that have examined the occurrence of sensory processing dysfunction and its components in Saudi Arabian children with autism. Therefore, this study investigated the manifestation of sensory processing dysfunction in autism and compared the functional components of sensory processing between Saudi Arabian children with and without autism. [Subjects and Methods] A convenience sample of 46 Saudi Arabian children with autism and 30 children without autism participated in this study. The sensory processing functions of both groups were assessed with the Short Sensory Profile. [Results] The overall findings indicated that 84.8% of children with autism demonstrated definite sensory processing dysfunction. The most prevalent sensory processing dysfunctions involved the under-responsive/seeks sensation (89.13%), auditory filtering (73.90%), and tactile sensitivity (60.87%) domains. Most of the children without autism (66.66%) demonstrated typical sensory function; the most prevalent sensory processing dysfunctions involved the tactile sensitivity (33.3%), under-responsive/seeks sensation (23.33%), and movement sensitivity (20%) domains. [Conclusion] Saudi Arabian children with and without autism have clinically significant sensory dysfunctions. However, the prevalence of those sensory dysfunctions in children with autism is significantly higher than in the children without autism. PMID:26157208

    The present study addresses the soil-to-plant transfer factors (TFs) of (226)Ra, (234)U and (238)U for 13 types of vegetables and agricultural crops planted under semi-arid environment in the northwestern part of Saudi Arabia. Crop plants along with plant-growing soils were collected from selected farms, which are irrigated from the non-renewable Saq aquifer, and investigated for their radioactivity content by means of alpha spectrometry after applying a radiochemical separation procedure. Hence, TF data for plant roots, green parts (stem and leaves) and fruits were calculated and contrasted to those reported in the literature. Substantial differences were observed in the TFs of Ra and U radioisotopes among plant species. In crop fruits, eggplant exhibited the highest uptake of (226)Ra (TF value of 0.11), while beans (0.16) have the highest TF for (234)U and (238)U. The geometric mean TF values indicated that the crop roots tend to accumulate Ra and U about four to six-folds higher than fruits. The relation between TF values and soil concentrations showed a weak correlation. Activity ratios between radionuclides in crop plants indicated the preferential translocation of U in fruits than Ra even though Ra is more available for root uptake. The fruit/root (F/R) ratios obtained for the investigated plants shown that pepper had the smallest F/R ratios (0.07 ± 0.01, 0.12 ± 0.02 and 0.11 ± 0.02 for (226)Ra, (234)U and (238)U, respectively), while the highest F/R ratios were observed in potatoes (0.71 ± 0.15, 0.44 ± 0.10 and 0.40 ± 0.08 for (226)Ra, (234)U and (238)U, respectively). The TF and F/R ratios data of natural radionuclides in the study region can hopefully improve the scientific knowledge for future studies. PMID:27108351

    Background Medical science is perceived as a stressful educational career, and medical students experience monstrous stress during their undergraduate studies, internship, and residency training, which affects their cognitive function, practical life, and patient care. In the present study, an assessment of the prevalence of self-perceived stress among new medical graduates during their internship training has been performed, and correlations of self-perceived stress with sex, marital status, and clinical rotations have been evaluated. Patients and methods Interns of the King Khalid, King Abdulaziz, and King Fahd University hospitals in Saudi Arabia were invited to complete a stress inventory known as the Kessler 10, which is used for stress measurement. Apart from stress evaluation, the questionnaire collected personal data, such as age, sex, and marital status, in addition to information relevant to hospital training, assigned duties, and clinical training rotations. Results Our results showed that nearly 73.0% of interns were under stressed conditions. Most of the interns were affected by a severe level of stress (34.9%), followed by mild (19.3%) and moderate (18.8%) levels of stress. The stress level was significantly higher (84.0%) among female interns in comparison with male interns (66.5%) (odds ratio =2.64; confidence interval =1.59–4.39; P<0.0002). There were statistically significant differences between the percentages of male and female interns (P≤0.047) at mild, moderate, and severe stress levels. Marital status had no role in causing stress. The highest stress level was reported by interns during the clinical rotations of medicine (78.8%), followed by surgery (74.7%), pediatrics (72.4%), obstetrics and gynecology (70.1%), and emergency (58.3%). The prevalence of stress among the interns and their corresponding clinical rotations in all three hospitals had significant linear correlations (r≥0.829, P≤0.041). Conclusion We found a significantly

    Assessment of groundwater quality is of utmost significance in arid regions like Saudi Arabia where the lack of present-day recharge and high evaporation rates coupled with increasing groundwater withdrawal may restrict its usage for domestic or agricultural purposes. In the present study, groundwater samples collected from agricultural farms in Hail (15 samples), Al Jawf (15 samples), and Tabuk (30 samples) regions were analyzed for their major ion concentration. The objective of the study was to determine the groundwater facies, the main hydrochemical process governing the groundwater chemistry, the saturation index with respect to the principal mineral phases, and the suitability of the groundwater for irrigational use. The groundwater samples fall within the Ca-Cl type, mixed Ca-Mg-Cl type, and Na-Cl type. Evaporation and reverse ion exchange appear to be the major processes controlling the groundwater chemistry though reverse ion exchange process is the more dominating factor. The various ionic relationships confirmed the reverse ion exchange process where the Ca and Mg in the aquifer matrix have been replaced by Na at favorable exchange sites. This phenomenon has accounted for the dominance of Ca and Mg ions over Na ion at all the sites. The process of reverse ion exchange was further substantiated by the use of modified Piper diagram (Chadha's classification) and the chloro-alkaline indices. Evaporation as a result of extreme aridity has resulted in the groundwater being oversaturated with aragonite/calcite and dolomite as revealed by the saturation indices. The groundwater samples were classified as safe (less than 10) in terms of sodium adsorption ratio (SAR) values, good (less than 1.25) in terms of residual sodium carbonate (RSC) values, and safe to moderate (between 0 and 3) in terms of Mg hazard for irrigation purposes. Though the high salinity groundwater in the three regions coupled with low SAR values are good for the soil structure, it can have a

    Background: The rate of preexisting diabetes mellitus (DM) in Saudi Arabia is one of the highest in the world. The role of preconception care (PCC) is well-established as a means of improving pregnancy outcomes in DM. Objectives: To assess the rate of preconception counseling, the level of PCC knowledge, and the rate of unplanned pregnancies in Saudi women with DM. Materials and Methods: A cross-sectional study was conducted among 355 Saudi women aged 18–49 years with self-reported DM. The study questionnaire contained variables about the provision of preconception counseling, knowledge of PCC facts, and the number of unplanned pregnancies after developing DM. The level of PCC knowledge was evaluated using a modified Likert scale. Statistical Package for Social Sciences 20 was used for statistical analysis. Descriptive statistics, mean and standard deviation, and percentages were calculated; t-test was used for statistical significance. Results: About one-third of the participants had received preconception counseling after being diagnosed with DM. Counseling on PCC for older and married participants was significantly less. Of the 355 participants, 42.8% had little or no PCC knowledge. All pregnancies that occurred after developing DM were unplanned. Conclusions: The rate of preconception counseling, the level of PCC knowledge in the studied Saudi women with DM is suboptimal, and none of the pregnancies that occurred after developing DM was planned. The study highlights the need for PCC programs that target all Saudi women of child-bearing age with DM, and their families starting at the age of puberty and at diagnosis of type 2DM, to optimize women's health and improve pregnancy outcomes.

    Background: Research on the attitudes of Saudi adults towards consanguinity is scarce. The study aimed to explore the attitudes towards consanguinity and its associations with socio-demographic characteristics in a sample of Saudi adults. Methods: A cross-sectional study was conducted using a self-administered questionnaire. A total of 386 outpatient waiting-area attendees at King Abdul-Aziz Medical City-Riyadh were included. Participants were asked about their socio-demographic characteristics, attitude towards consanguinity and the reasons behind this. Results: The positive attitude towards consanguinity among the study respondents was 48.1% with 95% confidence interval (42.91–53.33%). Social and traditional culture (59.9%) were found to be the predominant reasons for favoring consanguinity in Saudi Arabia. Evidence against a positive attitude towards consanguinity was noted in respondents who received medical information about consanguinity versus those who had not received medical information (42.3% vs. 57%, p-value = 0.008). According to the multivariate logistic model, the odds of a positive attitude towards consanguinity were 2 times higher for males (adjusted odds ratio [aOR]: 2.2; 95% CI: 1.147, 4.290) and 4.1 times higher in respondents in consanguineous marriages (aOR: 4.1; 95% CI: 2.350, 7.156). The odds of a positive attitude towards consanguinity were 50% less in respondents who received health information on consanguinity compared to those who had not received health information about consanguinity (aOR: 0.50; 95% CI: 0.253, 0.863). Conclusion: One in every two Saudi adults favors consanguinity however, Saudi men and women differ in their attitudes towards consanguinity. Receiving health information on consanguinity was associated with a negative attitude towards this practice. PMID:26835408

    This study was conducted on 3212 Saudi families to investigate the prevalence of consanguineous marriages. The families were interviewed and the information on the relationship between the husband and wife was obtained. The overall rate of consanguinity shows that 57.7% of the families screened were consanguineous. The most frequent were first cousin marriages (28.4%) followed by distant relative marriages (15.2%) and second cousin marriages (14.6%). The families were grouped according to the province of their origin and the consanguinity rates were calculated accordingly. There were slight differences in the consanguinity rates in the five provinces, which ranged from 52.1% to 67.7%. In each province first cousin marriages were the most frequently encountered pattern, ranging from 17.9% to 40.9%. The inbreeding coefficient (F) was calculated for each province and ranged from 0.020 to 0.030. Within each province, there were several significant differences among the populations in the different areas. The highest rate of consanguinity was 80.6% in Samtah and the lowest rate was around 34% in Abha in the South Western province. These results place Saudi Arabia among the countries of the world with a high rate of consanguinity. The possible consequences of increased consanguinity are presented and discussed. PMID:7473654

    This study was conducted to investigate phytophagous and predatory mites associated with vegetable plants in Riyadh, Saudi Arabia. Eight phytophagous and 10 predacious mites were collected from 14 species of vegetable crops covering five major production localities. Out of these 18 mite species, 13 species are new to the mite fauna of Saudi Arabia. In addition, the two species, Tenuipalpus punicae and Agistemus exsertus, are reported for the first time on vegetable crops in Saudi Arabia. For each mite species found, notes on host plant association and occurrence period are given. An illustrated key for the identification of the 18 mite species reported in this study is provided and this can be used to improve the IPM programs by applying the local natural predatory mites in controlling mite pests in Saudi Arabia.

    Medical education is perceived as being stressful, and a high level of stress may have a negative effect on cognitive functioning and learning of students in a medical school. This cross-sectional study was conducted to determine the prevalence of stress among medical students and to observe an association between the levels of stress and their academic performance, including the sources of their stress. All the medical students from year one to year five levels from the College of Medicine, King Saud University, were enrolled in the study. The study was conducted using Kessler10 psychological distress (K10) inventory, which measures the level of stress according to none, mild, moderate, and severe categories. The prevalence of stress was measured and compared with the five study variables, such as gender, academic year, academic grades, regularity to course attendance, and perceived physical problems. The response rate among the study subjects was 87% (n=892). The total prevalence of stress was 63%, and the prevalence of severe stress was 25%. The prevalence of stress was higher (p<0.5) among females (75.7%) than among males (57%) (odds ratio=2.3, chi2=27.2, p<0.0001). The stress significantly decreased as the year of study increased, except for the final year. The study variables, including being female (p<0.0001), year of study (p<0.001), and presence of perceived physical problems (p<0.0001), were found as independent significant risk factors for the outcome variables of stress. Students' grade point average (academic score) or regularity to attend classes was not significantly associated with the stress level. The prevalence of stress was higher during the initial three years of study and among the female students. Physical problems are associated with high stress levels. Preventive mental health services, therefore, could be made an integral part of routine clinical services for medical students, especially in the initial academic years, to prevent such

    Diatoms contribute to a substantial portion of primary production in the oceans and many lakes. Owing to their relatively heavy cell walls and high nutrient requirements, planktonic diatoms are expected to decrease with climate warming because of reduced nutrient redistribution and increasing sinking velocities. Using a historical dataset, this study shows that diatoms were able to maintain their biovolume with increasing stratification in Lake Tahoe over the last decades; however, the diatom community structure changed. Increased stratification and reduced nitrogen to phosphorus ratios selected for small-celled diatoms, particularly within the Cyclotella genus. An empirical model showed that a shift in phytoplankton species composition and cell size was consistent within different depth strata, indicating that altered nutrient concentrations were not responsible for the change. The increase in small-celled species was sufficient to decrease the average diatom size and thus sinking velocity, which strongly influences energy transfer through the food web and carbon cycling. Our results show that within the diverse group of diatoms, small-sized species with a high surface area to volume ratio were able to adapt to a decrease in mixing intensity, supporting the hypotheses that abiotic drivers affect the size structure of planktonic communities and that warmer climate favours small-sized diatom cells.

    Saudi Arabia is becoming aware that it is vulnerable to internal and external pressures which threaten its security. The strains of rapid modernization and threats from hostile neighbors are undermining the consensus which has held the widely diverse country together in a system of open communication. Influence by the Bedouin (ruling) and the ulama (religious) groups has predominated a traditional society determined to modernize and still remain conservative. Members of the ruling class are seeking to profit from the modernization process, but the common Saudi resists becoming an industrial laborer. Recent events in Mecca, Afghanistan and elsewhere illustrate how political pressures are affecting the country's leadership in the threat of armed conflicts over its oil supplies. (DCK)

    Objective. To assess the attitude and knowledge of the Saudi mothers toward newborn screening (NBS) program. Methods. A total of 425 Saudi women (only mothers who have at least one pregnancy) participated in the study from different regions in Saudi Arabia and completed the structured questionnaire which sought their views on the NBS services. Results. A majority of the participating women (91.1%) supported the NBS program and felt it was very important and useful. However, knowledge of NBS was found to be very limited and only 34.6% knew that NBS was a test to detect genetic disorders. A lack of communication and counseling to NBS clients by health authorities offering screening is implied. Conclusion. In general, there is a positive attitude towards the NBS program among Saudi women. However, they have several concerns to improve the availability of medication and formulas, genetic counseling, medical interventions, communication, education materials, and awareness.

    The Saudi Initiative for Asthma (SINA) provides up-to-date guidelines for healthcare workers managing patients with asthma. SINA was developed by a panel of Saudi experts with respectable academic backgrounds and long-standing experience in the field. SINA is founded on the latest available evidence, local literature, and knowledge of the current setting in Saudi Arabia. Emphasis is placed on understanding the epidemiology, pathophysiology, medications, and clinical presentation. SINA elaborates on the development of patient-doctor partnership, self-management, and control of precipitating factors. Approaches to asthma treatment in SINA are based on disease control by the utilization of Asthma Control Test for the initiation and adjustment of asthma treatment. This guideline is established for the treatment of asthma in both children and adults, with special attention to children 5 years and younger. It is expected that the implementation of these guidelines for treating asthma will lead to better asthma control and decrease patient utilization of the health care system. PMID:19881170

    Taif rose (Rosa damascena trigintipetala Dieck) is a sort of damask rose, which is considered as one of the most important economic products of Taif. In this study, the authors investigated the possible cytotoxic, genotoxic, antimutagenic and anticancer effect of concrete and absolute rose oils. The results showed that both concrete and absolute rose oils were cytotoxically and genotoxically safe at a dose of 10 μg/ml when tested on cultures of normal human blood lymphocytes. Also, the results showed significant antimutagenic activity at p < 0.001 for absolute rose oil at the same dose level when tested on cultures of normal human blood lymphocytes supplemented with 300 ng/ml mitomycin C (MMC). On the other hand, concrete and absolute oils exerted a cytotoxic activity against two kinds of human cancer cell lines: HepG2 and MCF7. Concrete oil showed cytotoxic activity against HepG2 and MCF7 with a half maximal inhibitory concentration (IC50) of 16.28 and 18.09 μg/ml, respectively, whereas absolute rose oil showed its cytotoxic activity against HepG2 and MCF7 with an IC50 of 24.94 and 19.69, respectively. From this study, it is concluded that concrete and absolute rose oils are cytotoxically and genotoxically safe at a dose of 10 μg/ml when tested on cultures of normal human blood lymphocytes. In addition, absolute oil has an antimutagenic activity at the same dose. Further investigations are needed to study the activity of higher doses of both oils in vitro and in vivo in experimental animals in order to evaluate the capability of using these oils as therapeutic for treatment of some kinds of cancers.

    Objectives. The aim of this cross-sectional study was to identify sleeping patterns among dental students and their association with self-reported bruxism in Riyadh Colleges of Dentistry and Pharmacy (RCsDP). Methods. A cross-sectional study was performed including 549 students (67 men and 482 women). A structured questionnaire was adopted from The PSQI (The Pittsburgh Sleep Questionnaire Index) used for data collection. It included questions which are categorized into sleeping habits, sleep-related symptoms, and additional questions concerning bruxism. This questionnaire was randomly distributed among all college preclinical and postclinical students. Sleep bruxism diagnosis was based on self-reported data. The data were analyzed using Chi-square tests through SPSS software for Windows. Results. Statistical analyses revealed significant correlations between self-reported bruxism and sleeping habits including sleep initiation (χ (2) = 22.6, p = 0.000), continuous sleep until morning (χ (2) = 19.2, p = 0.001), nighttime sleep duration (χ (2) = 20.2, p = 0.000), and length of daytime naps (χ (2) = 28.35, p = 0.000). There was an association between self-reported bruxism and sleeping-related symptoms including awakening early in the morning before the usual time without a cause (χ (2) = 16.52, p = 0.000) and increased nightmares (χ (2) = 13.7, p = 0.001). Conclusions. Poor sleeping pattern was an important factor among dental students, who reported sleep bruxism. PMID:27034672

    Background Uncorrected Refractive errors are the most common cause of avoidable visual impairment in children worldwide. Importance of school screening of refractive errors are one of the most important initiatives outlined in WHO Vision 2020 targets for control of avoidable visual impairment in children. But the benefit depends on the compliance of the spectacle wear by children. Purpose To study the prevalence and determinants of compliance of spectacle wear among children and to investigate the reasons of non compliance associated with the spectacle wear in primary school children. Materials and Methods This was a cross-sectional descriptive study of 631 students who had been prescribed spectacles for constant wear during school screening programme done by our Department of Optometry, College of Applied Medical Sciences, Qassim University during 2010–2011. After six months, experienced Optometrists conducted a follow-up visit where these students were assessed about spectacle compliance. Information on age, gender, type of refractive error, reasons for non compliance were collected and analyzed. Results The non-compliance rate of spectacle wear in primary school children is 66.80%. A significantly higher proportion of boys 244(69.13%) were not wearing their spectacles compared to girls 178 (64.03%) (P<0.05). Non-compliance was not related to age of the students (P<0.05), but older and myopic children were slightly more non-compliant. The main reasons for non-compliance in primary school boys and girls for using spectacles were disapproving spectacle wear by parents, not like to wear spectacles, broken spectacles and many children feel spectacles are not needed or causes head ache. Conclusions Comprehensive eye care for primary school children with refractive error is practised in Qassim Province, but limited information is available on the magnitude of the compliance for spectacle wear and their reasons. School children were not compliant because of many

    Approximately 5-10% of subjects with pre-diabetes eventually progress to diabetes every year. While inflammation is thought to be involved in the development of obesity-related type 2 diabetes mellitus (T2DM), the relation between inflammation and pre-diabetes remains largely unexplored. In this study we examined a comprehensive panel of 10 serum biomarkers involved in overweight and obese subjects with pre-diabetes. A total of 98 subjects (23 males, 75 females) were advised to reduce total intake of fat, increase fiber intake and physical activity. Serum cytokines, MCP and other hormones were assessed by multiplex cytokine profiling. Results show that CRP, IL-6, leptin, IL-10, MCP, resistin, serpin, and TNF-α were significantly lower after 12-months than baseline. Serum concentrations of other adipocytokines, including adipsin and leptin were modestly lower in the 12-month follow-up than baseline, but failed to reach statistical significance. Changes in HbA1c was found to be positively correlated with adipsin, CRP, IL-6, IL-10, resistin, serpin, and TNF-α. The results suggest that promotion of lifestyle changes for one year among overweight and obese subjects modestly changes several circulating inflammatory biomarkers which maybe favorable in reducing risk for T2DM progression.

    1983-01-01

    This study examines the transformation of American foreign policy in Saudi Arabia between the years 1933 and 1945. At the beginning of this period American-Saudi relations were negligible. However, by the end of World War II in 1945, American policy-makers had concluded that the Saudi Kingdom was a nation vital to America's long-term economic and strategic interests. This remarkable official about face was the result of several factors including the potential of Saudi Arabian oilfields, the shifting priorities of Washington policy-makers and the lobbying efforts of a Saudi-based American commercial concern, the Arabian American Oil Company (ARAMCO). ARAMCO entered Saudi Arabia in 1933. As the only all-American oil concession in the Middle East they feared European, especially British, interference in their operations. To forestall this possibility, real or imagined, the oilmen turned to Washington for help. Although official assistance was not immediately forthcoming, ARAMCO did find support in the Near Eastern Affairs Division (NEA) of the Department of State.

    Background/Aims: Hepatitis B virus (HBV) continues to be one of the most important viral pathogens in humans. Surface (S) protein is the major HBV antigen that mediates virus attachment and entry and determines the virus subtype. Mutations in S gene, particularly in the “a” determinant, can influence virus detection by ELISA and may generate escape mutants. Since no records have documented the S gene mutations in HBV strains circulating in Saudi Arabia, the current study was designed to study sequence variation of S gene in strains circulating in Saudi Arabia and its correlation with clinical and risk factors. Patients and Methods: A total of 123 HBV-infected patients were recruited for this study. Clinical and biochemical parameters, serological markers, and viral load were determined in all patients. The entire S gene sequence of samples with viral load exceeding 2000 IU/mL was retrieved and exploited in sequence and phylogenetic analysis. Patients and Methods: A total of 123 HBV-infected patients were recruited for this study. Clinical and biochemical parameters, serological markers, and viral load were determined in all patients. The entire S gene sequence of samples with viral load exceeding 2000 IU/mL was retrieved and exploited in sequence and phylogenetic analysis. Results: A total of 48 mutations (21 unique) were recorded in viral strains in Saudi Arabia, among which 24 (11 unique) changed their respective amino acids. Two amino acid changes were recorded in “a” determinant, including F130L and S135F with no evidence of the vaccine escape mutant G145R in any of the samples. No specific relationship was recognized between the mutation/amino acid change record of HBsAg in strains in Saudi Arabia and clinical or laboratory data. Phylogenetic analysis categorized HBV viral strains in Saudi Arabia as members of subgenotypes D1 and D3. Conclusion: The present report is the first that describes mutation analysis of HBsAg in strains in Saudi Arabia on both

    In this study, we introduce work which aims assess the loading of faults to failure under different stress regimes in a triaxial deformation apparatus. We explore experimentally the reshear of an existing fault in various orientations for particular values of (σ1 - σ3) and σ3' for contrasting loading systems - load-strengthening (equivalent to a thrust fault) with σ1' increasing at constant σ3', versus load-weakening (equivalent to a normal fault) with reducing σ3' under constant σ1'. Experiments are conducted on sawcut granite samples with fault angles at a variety of orientations relative to σ1 , ranging from an optimal orientation for reactivation to lockup angles where new faults are formed in preference to reactivating the existing sawcut orientation. Prefailure and postfailure behaviour is compared in terms of damage zone development via monitoring variations in ultrasonic velocity and acoustic emission behaviour. For example, damage surrounding unfavourably oriented faults is significantly higher than that seen around favourably orientated faults due to greater maximum stresses attained prior to unstable slip, which is reflected by the increased acoustic emission activity leading up to failure. In addition, we also experimentally explore the reshear of natural pseudotachylytes (PSTs) from two different fault zones; the Gole Larghe Fault, Adamello, Italy in which the PSTs are in relatively isotropic Tonalite (at lab sample scale) and the Alpine Fault, New Zealand in which the PSTs are in highly anisotropic foliated shist. We test whether PSTs will reshear in both rock types under the right conditions, or whether new fractures in the wall rock will form in preference to reactivating the PST (PST shear strength is higher than that of the host rock). Are PSTs representative of one slip event?

    Objectives: To determine the prevalence of self-medication and assess the knowledge, attitudes, and perception of consumers toward self-medication. Methods: This cross-sectional survey was conducted over 4 weeks in May 2011 in Riyadh city, Kingdom of Saudi Arabia. Community pharmacies within 5 areas of the city (North, South, West, East, and Middle) were randomly selected for the study. All consumers were approached to participate in the study, with the exception of those buying cosmetic and medicinal equipments. A validated self-administered questionnaire was used to collect the data. Results: A total of 538 out of 707 consumers attending community pharmacies in Riyadh city, agreed to participate in the study. Most responders were male (73%), 23-33 years old (35%), and college graduates (42%). A total of 285 medications were bought without a prescription. Of these, 149 (49%) medications should be dispensed by prescription only, and 155 (51%) were over the counter medications. The most common prescription medications dispensed without prescriptions were antibiotics (22%) and analgesics/antipyretics (19%). The most common reasons for buying medications without a prescription were that the symptoms were too minor to visit a doctor (54%), time saving (40%), and minor illnesses for which the participants knew the required treatment (40%). Overall, most participants had poor knowledge, and negative perceptions regarding self-medication. More than 68% of participants did not know whether the medicine they bought is a prescription-only or over the counter medication. Conclusion: Irresponsible self-medication is common in Saudi Arabia. Future studies should focus on improving the consumers’ awareness of self-medication and the proper use of medications. PMID:25737176

    Global warming is occurring at an alarming rate and predictions are that air temperature (Ta) will continue to increase during this century. Increases in Ta as a result of unabated production of greenhouse gases in our atmosphere pose a threat to the distribution and abundance of wildlife populations worldwide. Although all the animals worldwide will likely be affected by global warming, diurnal animals in the deserts will be particularly threatened in the future because Tas are already high, and animals have limited access to water. It is expected that Saudi Arabia will experience a 3–5 °C in Ta over the next century. For predicting the consequences of global warming for animals, it is important to understand how individual species will respond to higher air temperatures. We think that populations will not have sufficient time to make evolutionary adjustments to higher Ta, and therefore they will be forced to alter their distribution patterns, or make phenotypic adjustments in their ability to cope with high Ta. This report examines how increases in Ta might affect body temperature (Tb) in the animals of arid regions. We chose three taxonomic groups, mammals, birds, and reptiles (Arabian oryx, Arabian spiny-tailed lizard, vultures, and hoopoe larks) from Saudi Arabia, an area in which Ta often reaches 45 °C during midday in summer. When Ta exceeds Tb, animals must resort to behavioral and physiological methods to control their Tb; failure to do so results in death. The observations of this study show that in many cases Tb is already close to the upper lethal limit of around 47° C in these species and therefore allowing their Tb to increase as Ta increases are not an option. We conclude that global warming will have a detrimental impact on a wide range of desert animals, but in reality we know little about the ability of most animals to cope with change in Ta. The data presented should serve as base-line information on Tb of animals in the Kingdom for

    Background This study describes epidemiological data of non-Hodgkin’s lymphoma (NHL) diagnosed from 2001 to 2008 among Saudi men. Materials and methods Retrospective data from all NHL cancer cases among Saudi men recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008 were used. Descriptive statistics, analysis of variance, Poisson regression, and simple linear regression were also used. Results In total, 2,555 new cases of NHL were recorded between January 2001 and December 2008. The region of Riyadh, Saudi Arabia had the highest overall age-standardized incidence rate (ASIR) at 7.8, followed by the Eastern region at 6.8, and Makkah at 6.1 per 100,000 men; however, Jazan, Hail, and Baha had the lowest average ASIRs at 2.5, 3.7, and 3.9 per 100,000 men, respectively. The incidence-rate ratio for the number of NHL cases was significantly higher in Riyadh (4.68, 95% confidence interval [CI] 4.11–5.32), followed by Makkah (4.47, 95% CI 3.94–5.07), and the Eastern region of Saudi Arabia (3.27, 95% CI 2.90–3.69) than that in the reference region of Jazan. Jouf had the highest changes in the ASIRs of NHL among Saudi men from 2001 and 2008 (5.0 per 100,000 men). Conclusion A significant increase in the crude incidence rate and ASIR for NHL in Saudi Arabia between 2001 and 2008 was found. Riyadh, the Eastern region, and Makkah had the highest overall ASIR in Saudi Arabia. Jazan, Hail, and Baha had the lowest rates. Additionally, Riyadh, Makkah, and the Eastern region had the highest incidence-rate ratio for the number of NHL cases. Finally, Jouf had the highest changes in crude incidence rate and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of NHL among Saudi men.

    Objective The primary aim of the present study was to assess the quality of the Saudi Orthopedic Residency Program. Methodology As a comparator, a cross-sectional survey involving 76 Saudi residents from different training centers in Saudi Arabia namely; Riyadh, Jeddah, Medina, Abha, and Dammam and 15 Canadian. Results The results showed that Canadian residents read more peer-reviewed, scholarly articles compared with Saudi residents (P=0.002). The primary surgical role for residents was to hold retractors during surgery. The survey respondents strongly supported the ability to recommend removal of incompetent trainers. Saudi trainees were more apprehensive of examinations than Canadian trainees (P<0.0001). Most residents preferred studying multiple-choice questions before examinations. Saudi and Canadian participants considered their programs to be overcrowded. Unlike Canadian participants, Saudi trainees reported an inadequate level of training (P<0.0001). Conclusion Educational resources should be readily accessible and a mentorship system monitoring residents’ progress should be developed. The role of the resident must be clearly defined and resident feedback should not be ignored. Given the importance of mastering basic orthopedic operative skills for residents, meaningful remedial action should be taken with incompetent trainers. PMID:25278788

    Abstract Functional outcomes, length of stay (LOS), and discharge disposition have become frequent outcome measures among stroke patients after rehabilitation programs. To examine the trends of changes in functional outcomes, LOS, and discharge disposition in stroke patients discharged from an inpatient rehabilitation facility. All patients (n = 432) were admitted to a tertiary inpatient rehabilitation hospital in Riyadh, Saudi Arabia with stroke diagnoses from November 2008 to December 2014. The functional independence measure (FIM) instrument used to assess the patient's functional status. The LOS was measured as the number of days the patients spent in the hospital from the day of admission to the day of discharge. The FIM efficiency was used to measure the patient's rehabilitation progress. All of the variables of the prospectively collected data were retrospectively analyzed. There were significant changes by years in the total FIM ranging from 23 to 29 (P < 0.001) and subscores: FIM motor ranging from 20 to 26 (P < 0.001); FIM cognitive ranging from 1.8 to 3 (P < 0.001). The mean LOS remained constant, from 52 days in 2011 to 40 days in 2013. The FIM efficiency was stable between years and ranged from 0.52 to 0.72. The rates of discharge (to home) were significantly unstable and ranged from 100% in 2010 and 2011 to 92% in 2013. Our results suggest that functional outcomes in patients with stroke have improved after an inpatient stroke rehabilitation program between 2008 and 2014 even with a constant LOS. Discharge disposition has remained unstable over this period. To improve the efficiency of the stroke rehabilitation program in Saudi Arabia, there is a need to decrease the LOS and emphasize a comprehensive interdisciplinary approach. PMID:27495066

    Objectives: This study aimed to determine the prevalence of depression, anxiety and stress among Saudi Arabian dermatology patients and to assess associations with sociodemographic and clinical characteristics. Methods: This cross-sectional study was conducted among 300 consecutive dermatology patients visiting King Abdulaziz Medical City in Riyadh, Saudi Arabia, in August 2015. The Arabic version of the Depression, Anxiety and Stress Scale was used to screen for symptoms of depression, anxiety and stress. Quality of life (QOL) was assessed using the Dermatology Life Quality Index. Results: A total of 254 dermatology patients participated in the study (response rate: 84.7%). The prevalence of depression, anxiety and stress was 12.6%, 22.1% and 7.5%, respectively. The presence of at least one of these negative emotional states was noted among 24.4% of the cohort (95% confidence interval: 19.3–30.2%). Depression was significantly higher among subjects who lacked family support (26.5% versus 10.7%; P = 0.006) while anxiety was less common among patients who engaged in physical exercise (14.5% versus 29.4%; P = 0.005). According to the multivariate logistic regression analysis, poor QOL and a lack of family support were significant predictors of a negative emotional state. Conclusion: Almost a quarter of the studied Saudi Arabian dermatology patients were found to suffer from at least one negative emotional state. A lack of family support and poor QOL were the primary factors associated with a negative emotional state. Interventional studies are needed to examine the effects of social and family support on psychological conditions among Saudi Arabian dermatology patients. PMID:27226914

    Objectives: To investigate the prevalence and correlates of smartphone addiction among university students in Saudi Arabia. Methods: This cross-sectional study was conducted in King Saud University, Riyadh, Kingdom of Saudi Arabia between September 2014 and March 2015. An electronic self administered questionnaire and the problematic use of mobile phones (PUMP) Scale were used. Results: Out of 2367 study subjects, 27.2% stated that they spent more than 8 hours per day using their smartphones. Seventy-five percent used at least 4 applications per day, primarily for social networking and watching news. As a consequence of using the smartphones, at least 43% had decrease sleeping hours, and experienced a lack of energy the next day, 30% had a more unhealthy lifestyle (ate more fast food, gained weight, and exercised less), and 25% reported that their academic achievement been adversely affected. There are statistically significant positive relationships among the 4 study variables, consequences of smartphone use (negative lifestyle, poor academic achievement), number of hours per day spent using smartphones, years of study, and number of applications used, and the outcome variable score on the PUMP. The mean values of the PUMP scale were 60.8 with a median of 60. Conclusion: University students in Saudi Arabia are at risk of addiction to smartphones; a phenomenon that is associated with negative effects on sleep, levels of energy, eating habits, weight, exercise, and academic performance.

    Objectives: To evaluate the applicability of Moyers probability tables and to formulate more accurate mixed dentition prediction tables in the Saudi population. Methods: A cross-sectional study was conducted at the College of Dentistry, Kind Saud University, Saudi Arabia. The data were collected from 410 (203 males and 207 females) orthodontic study models, which had erupted mandibular permanent incisors, maxillary, mandibular canines and premolars. The mesiodistal widths were measured using a digital caliper with an accuracy of 0.01 mm. Student’s paired t-test was used to compare the mean width values derived from this study with the values derived using the Moyers table. Simple linear regression was used to evaluate the linear relationship between the combined mesiodistal widths of the mandibular permanent incisors and the canine-premolar segments in each dental arch. Results: The regression equations for the maxillary canine-premolar segment (males: Y=10.27+0.48X; females: Y=11.71 + 0.39X) and the mandibular canine-premolar segment (males: Y=9.71 + 0.40X; females: 11.28 + 0.39X) were used to formulate new probability tables on the Moyers pattern. Statistically significant differences were observed between predicted widths in our subjects and the widths obtained using Moyers tables. Conclusions: The new prediction tables derived in this study provided a more precise mixed dentition space analysis than Moyers prediction tables in estimating tooth dimensions in the Saudi population.

    Background: The aim of this study was to investigate the maximum mouth opening (MMO) in a representative sample of the Saudi adolescents. Materials and Methods: A total of 1825 Saudi adolescents (1007 males and 818 females) aged 12-16 years were randomly selected. The subjects were asked to open their mouth maximally till no further opening was possible and then the distance from the incisal edge of the maxillary incisors to incisal edge of the mandibular incisors was recorded. All data were analyzed using SPSS program and simple descriptive statistics of MMO with regard to gender and age groups were reported. The Student’s t-test and one-way analysis of variance were used to examine differences in mouth opening relative to gender and age groups. Results: The mean maximal mouth opening for males was 43.5 ± 4.23 mm (range 29-59 mm). The mean maximal mouth opening for females was 35.5 ± 4.4 mm (range 20-45 mm). There was a significant difference between the mouth opening of males and females in all the age group (P = 0.000). The mouth opening, regardless of gender, increases significantly with age from the age of 12 years to the age of 14 years (P = 0.000), then remained unchanged till the age of 16 years. Conclusion: The mouth opening of males is significantly higher than that of females in all the age group. There was a significant increase in MMO with age up to the age of 14 years regardless of gender. PMID:25628483

    This paper provides a database representing injury mortality in Dammam, Saudi Arabia, with the aim of establishing a system which will record information about the incidence of such deaths, identify new trends and give priority to violence prevention. The retrospective study was carried out on 64 fatalities from gunfire injuries at the Forensic Medicine Centre in Dammam, Saudi Arabia during the period from January 2002 - December 2006. The deaths included 55 cases of homicide, seven cases of suicide and two accidental shootings. Twenty-six victims were aged between 16-30 years and 24 victims were between 31-45 years. Fifty-nine of the cases were male. A handgun was the weapon used in 49 cases. The most common sites for the firearm entrance wounds were the head (45 cases) and the chest (35 cases). In the majority of cases (56.3%) a single shot was fired while in 15.6% of cases there were two shots. In 51.5% of cases no bullet was recovered from the body while a single bullet was recovered in 31.5% and two bullets in 6.2% of the cases. Distant range fire was observed in 65.6% of cases. Exit wounds were found on the head in 36.7% and on the chest in 28.7% of cases. The majority of victims were young males living in urban areas. This result should help in forming a strategy to improve the livelihoods of this group. The low incidence of alcohol abuse (one case, 1.56%) and only three cases (4.68%) of amphetamine abuse is significant. PMID:18754211

    Purpose Adenoviral keratoconjunctivitis is a major cause of ocular morbidity and may lead to visual loss. Adenovirus types 8, 19, and 37 may cause epidemic keratoconjunctivitis. The main objective of this study was to determine the types of adenoviruses causing keratoconjunctivitis in Saudi Arabia. Methods We conducted a non-interventional observational clinical study. Seventy three eyes from 65 patients who presented to The Eye Center in Riyadh, Saudi Arabia with clinical features of acute adenoviral keratoconjunctivitis were included. Each patient underwent complete clinical examination and features such as membranous reaction, conjunctival hemorrhage, subepithelial corneal infiltrates, and preauricular lymph node enlargement were recorded. Conjunctival swabs were obtained from patients with presumed acute viral conjunctivitis. Immunochromatography (IC) and restriction fragment length polymorphism polymerase chain reaction (PCR-RFLP) were performed on the conjunctival swabs obtained from each eye. Serotype identification was performed using direct sequencing technique. Results Forty-nine (67.1%) were adenovirus type 8, 8 (11.0%) were adenovirus type 3, 6 (8.2%) type 37, 5 (6.8%) were adenovirus type 4, and 2 (2.3%) type 19. The remaining 5 were types 14, 19, and 22. The prevalence of membranous conjunctivitis was highest (83%) among eyes with adenovirus type 37 while subepithelial corneal opacities were most commonly seen among eyes with adenovirus type 8 (47%). Immunochromatography tests were positive for adenovirus in 48 (65.7%) out of 73 eyes. Conclusions This study determined the types of adenoviruses causing keratoconjunctivitis at one center in Saudi Arabia. Direct sequencing techniques is an efficient, accurate, and rapid means of diagnosing adenoviral keratoconjunctivitis. The most common causes of adenoviral keratoconjunctivitis in Saudi Arabia were adenovirus types 8, 3, and 37. Membranous conjunctivitis and subepithelial opacities had the highest

    Liver disease is one of the major causes of morbidity and mortality across the world. According to WHO estimates, about 500 million people are living with chronic hepatitis infections resulting in the death of over one million people annually. Medicinal plants serve as a vital source of potentially useful new compounds for the development of effective therapy to combat liver problems. Moreover herbal products have the advantage of better affordability and acceptability, better compatibility with the human body, and minimal side effects and is easier to store. In this review attempt has been made to summarize the scientific data published on hepatoprotective plants used in Saudi Arabian traditional medicine. The information includes medicinal uses of the plants, distribution in Saudi Arabia, ethnopharmacological profile, possible mechanism of action, chemical constituents, and toxicity data. Comprehensive scientific studies on safety and efficacy of these plants can revitalise the treatment of liver diseases. PMID:25587347

    Measurement of indoor radon concentration was performed in Najran region in the south west of Saudi Arabia, using CR-39 dosimeter. Despite many previous studies on indoor radon concentrations in Saudi Arabia, the data available are still limited. The objective of this study, which is the first of its kind in the region, is to have preliminary data of radon in this region. Such measurement will contribute towards further studies in this region of Saudi Arabia. The indoor radon concentration was measured in the villages of Fara Al-Jabal and Badr Al-Janoob (about 2000 m above sea level), Hadadah and Al-Khanig (about 1700 m above sea level). It was found that radon distribution in these villages is normal skewed to the right, with a range of 9{+-}5 to 163{+-}32 Bqm{sup -3} and an average of 49{+-}2 Bqm{sup -3}. It was also found that the average radon concentration is independent of altitude. Our findings show that the values are below the safe limit of 150 Bqm{sup -3} set by the Environmental Protection Agency (EPA) of the USA

    Parameters of dental beauty change across time for varying reasons. Thus, an understanding of the factors that help or harm the attractiveness of a smile is an important step in creating attractive smiles. This study aimed to identify factors that affect smile perception and attractiveness among the Saudi population. A cross-sectional study was conducted among the Saudi population. Questionnaires were distributed to 130 dentists and final-year dental students, and to 130 laypersons. The questionnaire contained six smile photographs created by Photoshop(®) software. There was a statistically significant difference in scale ratings, based on participant background, for the "gummy" smile picture (P-value =0.003), diastema picture (P-value =0.000) and the "Reverse" smile picture (P-value =0.004). As for sex, males significantly underscored the gummy picture (P-value =0.009). Older people accepted the gummy smile less than did younger people, but diastema was considered as one of the variations that spoiled the attractiveness of the smile. "Dental background" participants significantly identified the ideal smile better than the "nondental" group. The perception of diastema as a sign of beauty among Saudi population in the past has definitely changed, according to the results of our study, where diastema and reverse smile received the lowest score in this survey.

    This study was designed to investigate the dietary components which are likely to contribute to osteoporosis in postmenopausal Saudi women. In the present study, 36 osteoporotic postmenopausal and 25 healthy postmenopausal women as cases and controls respectively were selected from Armed Forces Hospital, Riyadh, Saudi Arabia. The study has designed to collect the data about the general characteristics (age, marital status, education, number of pregnancies, activity level, income and housing), anthropometric measurements, medical history and dietary intake by using both the methods (24 h recall, food frequency questionnaire). Serum samples were analyzed for calcium, phosphorus, vitamin D and Para Thyroid Hormone (PTH) and they were correlated with Bone Mineral Density (BMD). Food intake items were correlated with hip, neck and spin BMD. In results, cases found significantly older than controls and had history of bone fractures. Cases were consumed significantly less dietary calcium than controls. Serum parameters did not show any significant differences. However significant correlation was found between serum level of PTH and calcium with BMD of spine and right neck femur respectively. Banana and Mataziz (locally prepared dish with vegetables) showed positive correlation with hip BMD. A negative significant correlation was found between Arabian coffee and right neck femur BMD. In conclusion, Saudi women require encouragement to consume adequate amounts of calcium, fruits and vegetables in combination with maintaining a daily physical activity and space in child birth.

    In this study, we assess the loading of faults to failure under different stress regimes in a triaxial deformation apparatus, both in dry and saturated conditions. We explore experimentally the reshear of an existing fault in various orientations for particular values of (σ_1 - σ_3) and σ_3' for contrasting loading systems - load-strengthening (equivalent to a thrust fault) with σ1' increasing at constant σ_3', versus load-weakening (equivalent to a normal fault) with reducing σ_3' under constant σ_1'. Experiments are conducted on sawcut granite samples with fault angles at a variety of orientations relative to σ_1, ranging from an optimal orientation for reactivation to lockup angles where new faults are formed in preference to reactivating the existing sawcut orientation. Prefailure and postfailure behaviour is compared in terms of damage zone development via monitoring variations in ultrasonic velocity and acoustic emission behaviour. For example, damage surrounding unfavourably oriented faults is significantly higher than that seen around favourably orientated faults due to greater maximum stresses attained prior to unstable slip, which is reflected by the increased acoustic emission activity leading up to failure. In addition, we explore reshear conditions under an initial condition of (σ_1' = σ_3'), then inducing reshear on the existing fault first by increasing σ_1'(load-strengthening), then by decreasing σ_3' (load-weakening), again comparing relative damage zone development and acoustic emission levels. In saturated experiments, we explore the values of pore fluid pressure (P_f) needed for re-shear to occur in preference to the formation of a new fault. Typically a limiting factor in conventional triaxial experiments performed in compression is that P_f cannot exceed the confining pressure (σ_2 and σ_3). By employing a sample assembly that allows deformation while the loading piston is in extension, it enables us to achieve pore pressures in

    Objective The aims of this study were to investigate the prevalence and distribution of dental anomalies in a group of Saudi subjects with cleft lip and palate (CLP), to examine potential sex-based associations of these anomalies, and to compare dental anomalies in Saudi subjects with CLP with published data from other population groups. Design This retrospective study involved the examination of pre-treatment records obtained from three CLP centers in Riyadh, Saudi Arabia, in February and March 2010. The pre-treatment records of 184 subjects with cleft lip and palate were identified and included in this study. Pre-treatment maxillary occlusal radiographs of the cleft region, panoramic radiographs, and orthodontic study models of subjects with CLP were analyzed for dental anomalies. Results Orthopantomographs and occlusal radiographs may not be reliable for the accurate evaluation of root malformation anomalies. A total of 265 dental anomalies were observed in the 184 study subjects. Hypodontia was observed most commonly (66.8%), followed by microdontia (45.6%), intra-oral ectopic eruption (12.5%), supernumerary teeth (12.5%), intra-nasal ectopic eruption (3.2), and macrodontia (3.2%). No gender difference in the prevalence of these anomalies was observed. Conclusions Dental anomalies were common in Saudi subjects with CLP type. This will complicate the health care required for the CL/P subjects. This study was conducted to epidemiologically explore the prevalence of dental anomalies among Saudi Arabian subjects with CLP.

    Vitamin D deficiency has emerged as a public health problem worldwide due to its important role in health and disease. The present work is intended to examine prevalence of vitamin D deficiency among pregnant Saudi women and related risk factors. A cross-sectional study was carried out at King Fahad Medical City in Riyadh, Saudi Arabia. Serum 25-hydroxy vitamin D (25(OH)D) was measured by enzyme-linked immunosorbent assay in 160 pregnant women during the first trimester of pregnancy. Socio-demographic, lifestyle and maternal characteristics were collected and vitamin D intake was assessed using a 24-h dietary recall. Weight and height were measured using standardized methods. Vitamin D deficiency (25(OH)D < 50 nmol/L) and insufficiency (25(OH)D = 50–74 nmol/L) were reported in 50% and 43.8% of the study sample, respectively. Median serum 25(OH)D concentration was 49.9 nmol/L. Adequate vitamin D intake (≥600 IU/day) was reported among only 8.1% of pregnant women. Age group, educational level, sun exposure frequency and daytime and daily practice of exercise were significantly associated with vitamin D status. Overall, vitamin D deficiency was common among pregnant Saudi women in Riyadh. Steps should be taken to address the current situation, including increased sunlight exposure, consumption of fatty fish, and vitamin D supplements. PMID:26861386

    The purpose of this exploratory study is to provide an overview of a web-based health educational site created by the King Faisal Specialist Hospital and Research Center (KFSH&RC) in the Kingdom of Saudi Arabia (KSA). Sources of data included two interviews with Saudi IT personnel, three health educators, and two medical consultants working at KFSH&RC. The interviews ranged between 45 minutes and 120 minutes. The KFSH&RC website was also searched for the type of health information content posted. Results show that the KFSH&RC web-based health educational site provides health information through a medical encyclopedia, a social networking platform, health educational links, and targeted health information for children, which includes tools such as games and coloring books. Further research is needed on the effectiveness of the KFSH&RC web-based health education site in terms of improving knowledge and changing behavior of Saudi patients. The study recommends that targeted web-based health education strategies should be developed to reach large rural populations which have inadequate computer skills and limited access to the internet.

    Riyadh city and central part of Saudi Arabia are located in the Arabian Plat which is known as a relativity stable platform. However, we have been able to determine some events that were caused by local faults. In addition, we have been able to record some regional Earthquakes that cussed by tectonic movements. Most of these local events are not felt. The Institute of Astronomy and Geophysics Research at King Abdulaziz City for Science and Technology installed nine earthquake portable stations in central part of Saudi Arabia around Riyadh city to record local and micro- seismicty events. We are using digital recorders (RefTek 72A) for data acquisition, and SAISAN, HYPOINVERSE software for analyses. Currently, I am using different types of velocity models, and I am developing a map that shows some micro-earthquake events for that region. In addition, it includes some regional events. The objective of this study is to define the active faults in central part of Saudi Arabia, and this study will not only yield additional information regarding the tectonic setting, but also revised hazard assessments for the region.

    To limit the spread of Middle East respiratory syndrome coronavirus (MERS-CoV) in Saudi Arabia, the Ministry of Health tried to raise public awareness using different public campaigns. We aimed to measure public awareness of MERS in Saudi Arabia. A cross-sectional study was conducted between May and June 2014 using a newly designed Arabic questionnaire that was distributed and completed online. We analyzed the response of 1149 respondents across Saudi Arabia. We found that 97% of the participants were aware of MERS. In addition, 72% realized that coughing and sneezing could spread the infection. Furthermore, 83% thought that some patients with MERS could be cured. Moreover, 62% knew that no vaccine can prevent the disease. However, only 36% realized that taking antibiotics will not stop the infection, and only 41% recognized that no medication has yet been manufactured to treat it. Regarding protection measures, 74% used hand sanitizers, 43% avoided crowded places, and 11% wore masks in public places. Moreover, only 47% knew that bats and camels are the primary source of the virus. As anticipated, this level of awareness varied between the different categories of the studied population. Female, married, older, and more educated participants were significantly more knowledgeable about the disease. Public awareness of MERS is generally sufficient. However, some false beliefs about treatment were fairly common. In addition, almost half of the population remains unaware that bats and camels are the most likely sources of the virus.

    Objectives The objectives of this study were to assess serum 25OHD level among healthy Saudi population of Qassim region, besides socio-demographic characters, dietary habits, sun exposure and common symptoms of vitamin D deficiency were also evaluated. Subjects and Methods One hundred and eighty healthy males and females subjects above the age of 18 years were randomly selected from five primary health care centers of Qassim region. A predesigned structured questionnaire was administered by the doctor working in Primary Health Care Center and blood sample was obtained for measuring vitamin D (serum 25 OHD) level. Vitamin D sufficiency was defined as serum level of 25 OHD 30ng/ml or above. A level ranging 20 to 29 ng/ml was considered as vitamin D insufficiency, whereas below 20ng/ml as vitamin D deficiency. Results Out of 180 study participants, 51(28.3%) subjects were vitamin D deficient, 71 (39.4%) were vitamin insufficient and 58 (32.2%) had normal vitamin D level. Commonest symptom of vitamin D deficiency was bone pain (20%) and fatigue (11.1%). Conclusion Vitamin D inadequacy is a major public health problem in Saudi population. The prevalence of vitamin D deficiency/insufficiency among healthy Saudi population residing in Qassim region is 67.8%. If the issue is not urgently addressed it could lead to serious health consequences. PMID:23267289

    Background: Patient’s rights are worldwide considerations. Saudi Patient’s Bill of Rights (PBR) which was established in 2006 contained 12 items. Lack of knowledge regarding the Saudi PBR limits its implementation in health facilities. This study aimed to investigate the knowledge of health professions’ students at College of Applied Medical Sciences (CAMS) Riyadh Saudi Arabia regarding the existence and content of Saudi PBR as well as their attitude toward its ineffectiveness. Methods: A 3-parts survey was used to collect data from 239 volunteer students participated in the study. Data were analyzed by descriptive and analytical statistics using SPSS. Results: Results showed that although the majority of students (96.7%) believe in the ineffectiveness of patient’s rights, half (52.3%) of them had perceptual knowledge regarding the existence of Saudi PBR and only 7.9% of them were knowledgeable about some items (1–4 items) of the bill. Privacy and confidentiality of patient was the most common known patient’s rights. Students’ academic level was not correlated to neither their knowledge regarding the bill existence or its content nor to their attitude toward the bill. The majority of the students (93%) reported that only one course within their curriculum was patient’s rights-course related. About one quarter (23.4%) of the students reported that teaching staff used to mention patient’s rights in their teaching sessions. Conclusion: The Saudi health professions students at CAMS have positive attitude toward the ineffectiveness of patient’s rights nevertheless they showed limited knowledge regarding the existence of Saudi PBR and its contents. CAMS curriculums do not support the subject of patient’s rights. PMID:25197675

    Streptococcus pneumoniae (pneumococcus) is the leading cause of morbidity and mortality worldwide. Saudi Arabia is a host to millions of pilgrims who travel annually from all over the world for Umrah and the Hajj pilgrimages and are at risk of developing pneumococcal pneumonia or invasive pneumococcal disease (IPD). There is also the risk of transmission of S. pneumoniae including antibiotic resistant strains between pilgrims and their potential global spread upon their return. The country also has unique challenges posed by susceptible population to IPD due to people with hemoglobinopathies, younger age groups with chronic conditions, and growing problem of antibiotic resistance. Since the epidemiology of pneumococcal disease is constantly changing, with an increase in nonvaccine pneumococcal serotypes, vaccination policies on the effectiveness and usefulness of vaccines require regular revision. As part of the Saudi Thoracic Society (STS) commitment to promote the best practices in the field of respiratory diseases, we conducted a review of S. pneumoniae infections and the best evidence base available in the literature. The aim of the present study is to develop the STS pneumococcal vaccination guidelines for healthcare workers in Saudi Arabia. We recommend vaccination against pneumococcal infections for all children <5 years old, adults ≥50 years old, and people ≥6 years old with certain risk factors. These recommendations are based on the presence of a large number of comorbidities in Saudi Arabia population <50 years of age, many of whom have risk factors for contracting pneumococcal infections.

    2001-06-01

    The authors reviewed the domestic chemical injury experience in two major government hospitals in Saudi Arabia to determine the most common causative agents and the circumstances of the injury in order to give recommendations for their prevention and reduction of their morbidity. A total of 59 cases were included. The mean age was 25 years and the male to female ratio was 3:1. Alkali drain cleaners were the major cause of chemical burns in the series and this was seen in 75% of the total study population. The remaining 25% of cases resulted from concentrated sulfuric acid, car battery acid and topical application of medical herbs by non-professionals. Unfortunately, immediate water lavage was not done in the majority of alkali and acid burns and hence skin grafting was required in most patients. It was concluded that efforts for prevention of chemical burns in Saudi Arabia should be directed towards education of the population regarding the proper use of alkali cleaners for clogged drains. These cleaners and battery acid containers should also be kept in a safe place away from the reach of children. Furthermore, a warning to the public regarding the non-professional use of medical herbs should be given. Finally, increased awareness among the Saudi population as to the need for prompt water irrigation of chemical burns should help reduce the morbidity from these injuries. PMID:11348747

    Context Healthcare organisations in Saudi Arabia are striving to improve patient safety and quality of care through implementation of safety systems and creating a culture of safety. Objective The purpose of this study to evaluate the extent to which the culture supports patient safety at Saudi hospitals. Data Collection A survey questionnaire was distributed hospital-wide in 13 general hospitals in Riyadh city, Saudi Arabia, to 223 health professionals including nurses, technicians, managers and medical staff. Measurement The Hospital Survey on Patient Safety Culture questionnaire was used to identify dimensions of patient safety culture. Results Overall Patient Safety Grade was rated as excellent or very good by 60% of respondents, acceptable by 33% and failing or poor by 7%. More than half of respondents thought that managers overlook safety problems that happen over and over. Areas of strength for most hospitals were organisational learning/continuous improvement, teamwork within units, feedback and communication about errors. Areas with potential for improvement for most hospitals were under-reporting of events, non-punitive response to error, staffing, teamwork across hospital units. Conclusion Leadership is a critical element to the effectiveness of patient safety initiatives. Response to errors is an important determinant of safety culture in healthcare organisations. In order for healthcare organisations to create a culture of safety and improvement, they must eliminate fear of blame and create a climate of open communication and continuous learning.

    2016-01-01

    Over recent decades, the use of portfolios in medical education has evolved, and is being applied in undergraduate and postgraduate programs worldwide. Portfolios, as a learning process and method of documenting and assessing learning, is supported as a valuable tool by adult learning theories that stress the need for learners to be self-directed and to engage in experiential learning. Thoughtfully implemented, a portfolio provides learning experiences unequaled by any single learning tool. The credibility (validity) and dependability (reliability) of assessment through portfolios have been questioned owing to its subjective nature; however, methods to safeguard these features have been described in the literature. This paper discusses some of this literature, with particular attention to the role of portfolios in relation to self-reflective learning, provides an overview of current use of portfolios in undergraduate medical education in Saudi Arabia, and proposes research-based guidelines for its implementation and other similar contexts.

    Background. Malondialdehyde (MDA) has been implicated in the development of many acute inflammatory, autoimmune diseases as well as chronic inflammatory metabolic disorders. Involvement of inflammatory response and oxidative stress is currently suggested as a mechanism underlying development of diabetes and its complications. Objective. To evaluate the clinical utility of MDA, macrophage migration inhibitory factor (MIF), LDL-C/HDL-C, and TG/HDL-C ratio as noninvasive laboratory markers for prediction of T2DM vascular complications. Method. 63 Saudi T2DM patients and 16 age and sex matched controls were included. Serum MDA and MIF were assayed by thiobarbituric acid reactive substances and ELISA, respectively. TG/HDL-C and LDL-C/HDL-C ratios were calculated. Results. Uncontrolled DM patients had significantly higher levels of MDA, MIF, TG/HDL-C, and LDL-C/HDL-C ratios when compared with controlled DM patients and control group (p < 0.001). MDA had 100% sensitivity and 88% specificity. MIF showed 97% sensitivity and 100% specificity and LDL-C/HDL-C had 97% sensitivity and 95% specificity. Meanwhile, TG/HDL-C had the lowest sensitivity and specificity in identifying diabetic patients who would suffer from vascular complications. Conclusion. MDA, MIF, and LDL-C/HDL-C could be new predictors of metabolic disturbance which promote vascular complications in T2DM. PMID:27298517

    2013-01-01

    Abstract Twelve agencies of the United Nations, including the World Health Organization, have issued a joint statement that calls on Member States to replace the compulsory detention of people who use opioids in treatment centres with voluntary, evidence-informed and rights-based health and social services. The arguments in favour of this position fall into three broad categories: Compulsory treatment centres infringe on an individual’s liberty, they put human beings at risk of harm, and evidence of their effectiveness against opioid dependence has not been generated. The United Nations statement underscores that although countries apply different criteria for sending individuals to compulsory treatment centres, detention often takes place without due process, legal safeguards or judicial review. This clearly violates internationally recognized human rights standards. Furthermore, people who are committed to these centres are often exposed to physical and sexual violence, forced labour and sub-standard living conditions. They are often denied health care, despite their heightened vulnerability to HIV infection and tuberculosis. Finally, there is no evidence, according to the statement, that these centres offer an environment that is conducive to recovery from opioid dependence or to the rehabilitation of commercial sex workers or of children who have suffered sexual exploitation, abuse or lack of care and protection. The author of this paper sets forth several arguments that counter the position taken by the United Nations and argues in favour of compulsory treatment within a broader harm reduction strategy aimed at protecting society as well as the individual concerned.

    Mothers' instigation of complementary feeding before their infant reaches 6 months old risks shortening their breastfeeding duration, and high morbidity and mortality for their child. Complementary feeding practices require further investigation in Saudi Arabia. The present study aims to evaluate complementary feeding practices, and to establish which factors are associated with the early introduction of complementary feeding in the Saudi Arabian context. Cross-sectional research was conducted with 632 mothers of infants aged between 4 and 24 months attending five primary health care centers (PHCCs) between July and December 2015 in Saudi Arabia. Data on participants' socio-demographic characteristics and complementary feeding practices were collected via structured questionnaires. A regression analysis identified the factors associated with the early introduction of solid foods, defined as before 17 weeks. 62.5% of the study's infants received solid foods before reaching 17 weeks old. The maternal factors at higher risk of early introduction of solids were: younger age; Saudi nationality; shorter education; employment within 6 months post-birth; caesareans; not breastfeeding fully for six weeks post-birth, and living in low-income households. Complementary feeding prior to 6 months postpartum was common in Saudi Arabia. Public health interventions are needed to reduce early complementary feeding, focusing on mothers at highest risk of giving solids too early. PMID:27420081

Public health interventions are needed to reduce early complementary feeding, focusing on mothers at highest risk of giving solids too early. PMID:27420081

    Abstract Apis mellifera jemenitica Ruttner (= yemenitica auctorum: vide Engel 1999) has been used in apiculture throughout the Arabian Peninsula since at least 2000 BC. Existing literature demonstrates that these populations are well adapted for the harsh extremes of the region. Populations of Apis mellifera jemenitica native to Saudi Arabia are far more heat tolerant than the standard races often imported from Europe. Central Saudi Arabia has the highest summer temperatures for the Arabian Peninsula, and it is in this region where only Apis mellifera jemenitica survives, while other subspecies fail to persist. The indigenous race of Saudi Arabia differs from other subspecies in the region in some morphological, biological, and behavioral characteristics. Further taxonomic investigation, as well as molecular studies, is needed in order to confirm whether the Saudi indigenous bee populations represent a race distinct from Apis mellifera jemenitica, or merely an ecotype of this subspecies.

    The Kingdom of Saudi Arabia includes fauna from three zoogeographic regions: the Afrotropical, Oriental, and Palaearctic regions. To study the mosquito (Diptera: Culicidae) fauna of these regions in Saudi Arabia, larval collections were made at 15 sites during 2005-2006. Thirty-three species representing nine genera were found. Six species, Anopheles culicifacies Giles s.l., Anopheles subpictus Grassi s.l., Culex arbieeni Salem, Culex simpsoni Theobald, Culex univittatus Theobald, and Ochlerotatus detritus Haliday are reported for the first time for Saudi Arabia. An annotated checklist and an illustrated key to the fourth-instar larvae of the 33 species are presented, along with some remarks about problematic species. Eleven species of genus Anopheles Meigen, five species of tribe Aedini, 13 species of genus Culex L., two species of genus Culiseta Felt, one species of genus Lutzia Theobald, and one species of genus Uranotaenia Lynch Arribátlzaga were recorded during the study.

    Land-use change and climate change are driving a global biodiversity crisis. Yet, how species' responses to climate change are correlated with their responses to land-use change is poorly understood. Here, we assess the linkages between climate and land-use change on birds in Neotropical forest and agriculture. Across > 300 species, we show that affiliation with drier climates is associated with an ability to persist in and colonise agriculture. Further, species shift their habitat use along a precipitation gradient: species prefer forest in drier regions, but use agriculture more in wetter zones. Finally, forest-dependent species that avoid agriculture are most likely to experience decreases in habitable range size if current drying trends in the Neotropics continue as predicted. This linkage suggests a synergy between the primary drivers of biodiversity loss. Because they favour the same species, climate and land-use change will likely homogenise biodiversity more severely than otherwise anticipated. PMID:27396714

    Obesity is a major global health problem and predisposes individuals to several comorbidities that can affect life expectancy. Interventions based on lifestyle modification (for example, improved diet and exercise) are integral components in the management of obesity. However, although weight loss can be achieved through dietary restriction and/or increased physical activity, over the long term many individuals regain weight. The aim of this article is to review the research into the processes and mechanisms that underpin weight regain after weight loss and comment on future strategies to address them. Maintenance of body weight is regulated by the interaction of a number of processes, encompassing homoeostatic, environmental and behavioural factors. In homoeostatic regulation, the hypothalamus has a central role in integrating signals regarding food intake, energy balance and body weight, while an ‘obesogenic' environment and behavioural patterns exert effects on the amount and type of food intake and physical activity. The roles of other environmental factors are also now being considered, including sleep debt and iatrogenic effects of medications, many of which warrant further investigation. Unfortunately, physiological adaptations to weight loss favour weight regain. These changes include perturbations in the levels of circulating appetite-related hormones and energy homoeostasis, in addition to alterations in nutrient metabolism and subjective appetite. To maintain weight loss, individuals must adhere to behaviours that counteract physiological adaptations and other factors favouring weight regain. It is difficult to overcome physiology with behaviour. Weight loss medications and surgery change the physiology of body weight regulation and are the best chance for long-term success.

    Arid countries like Saudi Arabia often depend on fossil groundwater. Hence, thorough studies of the available resources are crucial. In the course of such investigations, analyses of δ18O and δD are frequently applied to constrain the provenance of the waters and to reconstruct the (paleo)climatic conditions during their recharge. Yet, to be able to evaluate the isotopic signature of the groundwater, one also has to know the isotopic composition of current precipitation. Although a few rain water analyses are available for Central Saudi Arabia in the literature - mostly in unpublished consultant reports - a Local Meteoric Water Line has never been established. To complement the available data, 28 rain events occurring in Riyadh between 2009 and 2013 were studied for their stable isotope composition. Samples were collected as integral samples, i.e., they represent the entire precipitation event. Moreover, one event was sampled several times, aiming at an evaluation of intra-storm variability. During selected storms, a grab sample was taken for 3H analysis. The event samples showed δ18O and δD values scattering between -6.5 and +9.5 and between -30 and +50 ‰ V-SMOW, respectively. In the course of the event that was sequentially sampled, a proceeding isotopic depletion was observed with respect to both isotopes. The relatively large ranges of δ-values for 18O and D of approximately 7 and 38 ‰ V-SMOW highlight the general need for integral sampling. The obtained grab samples are characterized by moderate 3H concentrations of a few Tritium Units. Further results will be presented and discussed in view of associated weather data (e.g. rain amount and temperature) and the probable moisture sources derived from back-trajectories, which were calculated using HYSPLIT (Hybrid Single-Particle Lagrangian Integrated Trajectory Model; Draxler & Rolph, 2003).

    Metabolic syndrome (MS) is a combination of factors that increases the risk of cardiovascular atherosclerotic diseases including diabetes, obesity, dyslipidemia, and high blood pressure. Cardiovascular diseases are one of the leading causes of death in the adult Saudi population where the increase in cardiovascular-related mortality is augmented by the rise in the prevalence of MS. Metabolic syndrome is a multi-factorial disorder influenced by interactions between genetic and environmental components. This review aims to provide a comprehensive assessment of studied environmental and genetic factors explaining the prevalence of MS in the Kingdom of Saudi Arabia. Additionally, this review aims to illustrate factors related to the population genetics of Saudi Arabia, which might explain a proportion of the prevalence of MS. PMID:26739969

  9. Exports and Economic Growth in Saudi Arabia: A VAR Model Analysis

    NASA Astrophysics Data System (ADS)

    Kingdom of Saudi Arabia is a developing country and is rich in natural resources. The export sector plays an important role in the economic growth of a country. Basically, economic growth of a country depends on the nature and type of relationship between exports and domestic economic growth. Modern econometric techniques such as Vector Auto-Regression (VAR), Impulse Response Function (IFR) and the Granger-causality test were applied to determine long-term relationship between exports and domestic economic growth from 1970 to 2005. It was found that the export sector of Saudi Arabia caused a significant effect on the economic growth and a positive influence on other economic activities in the long run. Also, a long-term equilibrium existed among the various macroeconomic variables such as RGDP, RC, RG, RI, RX and RM considered in the study. It is apparent that a steady state condition can be reached between exports and economic growth in Saudi Arabia.

    Objectives: To explore the challenges facing pharmacovigilance in Saudi Arabia and formulate recommendations to improve it from the perspective of healthcare professionals in Saudi Arabia. Methods: This was a qualitative study of 4 focus group discussions with pharmacists, physicians, and academicians held under the auspices of the King Saud University School of Pharmacy and the Center for Medicine in the Public Interest, Riyadh, Saudi Arabia. A total of 29 eligible healthcare professionals were invited to participate in the discussion. The predefined themes of the study were the current practice and major challenges facing pharmacovigilance in regulatory bodies, hospitals, the community, and academia, as well as recommendations to improve pharmacovigilance practice. Result: Of the 29 participants invited, 27 attended the discussion. Challenges facing regulatory bodies included complicated adverse drug reactions (ADR) reporting forms, lack of feedback on ADRs submitted to the Saudi Food and Drug Authority, lack of decisions from the local authority to withdraw medications, and lack of data on pharmacovigilance. The challenges to pharmacovigilance in hospitals included the lack of knowledge of the significance of ADR reporting, workload, blaming culture, and lack of collaboration between regulatory bodies and hospitals. However, challenges facing pharmaceutical industries included the lack of drug manufacturers in Saudi Arabia and lack of interest in pharmacovigilance. Recommendations to improve pharmacovigilance included the need for communication, stronger regulatory requirements, the need for research, the need for unified ADRs reporting, and continuous education and training. Conclusion: The study has identified the challenges facing pharmacovigilance in Saudi Arabia and made certain recommendations to overcome them. These recommendations might be helpful for regulatory bodies to enhance spontaneous reporting and promote pharmacovigilance. PMID:26318468

    Allogeneic HSCT is the only curative treatment for SCD. In this study, we estimated the number of Saudi patients with SCD who are candidates for HSCT. We used the presence of overt stroke, recurrent ACS, and frequent severe pain crisis as indications for HSCT. We calculated the frequencies of these complications among a Saudi SCD cohort of 376 patients with SCD, 250 from SW and 126 from Eastern (E) provinces. We found that 59 (23.6%) of SW patients were transplant candidates compared to 22 (17.4%) from E province. It is estimated that about 61 000 patients with SCD live in Saudi Arabia. Thus, the projected number of Saudi patients with SCD who are candidates for HSCT is 10 536 patients. Of those, 2148 are children. The burden of SCD on HSCT centers in Saudi Arabia is substantial and is difficult currently to meet the demand. We recommend recruiting/training more transplant physicians and nurses, expand current capacity of centers if feasible, and open new transplant centers to make HSCT a practical therapeutic option for patients with severe SCD in Saudi Arabia.

    Demographic movements likely to be taking place in Saudi Arabia were hypothesized on the basis of general knowledge. The discussion reports on population size, general Arab demographic patterns, general determinants of fertility, Arab fertility patterns, Saudi fertility patterns, mortality in general, mortality in the Middle East, mortality in Saudi Arabia, Saudi Arabian population growth, immigration, the changing composition of the work force, and third plan targets. Some doubt exists as to the size of Saudi Arabia's population, but there is little question that the total is growing rapidly. This expansion is taking place through stepped up immigration and a relatively high natural growth of indigenous Saudis, but statistics on population size, structure, and on the number of births and deaths leaves the magnitude of a number of important demographic trends in doubt. Yet, considerable evidence exists that several of the Arab countries in the region with fairly good demographic data are likely to have similar demographic patterns. In depth analysis of the demographic dynamics of these countries, particularly Jordan and Kuwait, identified several common elements bearing on several key parameters. Using what Saudi data is available and making comparisons with these neighboring countries, one can, based on expected levels of birth and death rates, indirectly infer the natural growth of Saudi Arabia's population. With several notable exceptions, Saudi Arabia's demographic patterns show a marked similarity to those experienced in the region as a whole. The average rate of population growth in both Saudi Arabia and the Arab region is about 3% a year and in both instances fertility rates are high. The demographic structure of these countries is characterized by the youthfulness of the population. In most of the Arab countries, the population aged 15 years or under accounts for over 48% of the population. The rate of the economically active population is low, ranging from

    Background The present study reviews the epidemiological data on corpus uteri cancer among Saudi women, including its frequency, crude incidence rate, and age-standardized incidence rate (ASIR), adjusted by region and year of diagnosis. Methods A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0), followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0), and the eastern region, at 9.9 times (95% CI: 5.6–17.6). The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease. Riyadh, the eastern region, and Makkah had the highest overall disease ASIRs and incidence rate ratios, while Jazan, Najran, and Qassim had the lowest rates. Finally, the northern region experienced the greatest changes in ASIR during the studied period. Further analytical studies are necessary to determine potential risk factors of corpus uteri cancer among female Saudi

    Mineralogical properties of soils along a 500 km east-west transect of an eastern province of Saudi Arabia were examined. Mineralogical composition of soils along the eastern coastal playa near Al Qatif is mostly gypsum or calcite in the whole soil, and smectite among layer silicate minerals in the clay fraction (<2mm). In soils of the Harad area palygorskite and smectite are the major layer silicate minerals. In the Al Kharj area kaolinite and smectite are the major clay minerals. Small amounts of chlorite occur in all soils studied although it varies in thermal stability and the amount is very small in Al Kharj 11 and Al Kharj Mountain surface soils. In the entire eastern region mica and vermiculite are present in the soil clays. The results of transmission electron microscpoy and x-ray diffraction analyses show that acicular palygorskite is widely distributed in the eastern-region soils. Palygorskite is believed to originate from the underlying Mio-Pliocene limestone in the basin, and to be redistributed by alluvial and eolian processes.

    Objectives: This study aimed to evaluate attitudes, perceptions and perceived barriers towards health research among Saudi Arabian undergraduate medical students. Methods: This cross-sectional study took place between August and October 2014 and included 520 students from five medical schools across Saudi Arabia. An anonymous online survey with 21 close-ended questions was designed to assess students’ attitudes towards research, contribution to research-related activities, awareness of the importance of research, perception of available resources/opportunities for research, appreciation of medical students’ research contributions and perceived barriers to research. Responses were scored on a 5-point Likert scale. Results: A total of 401 students participated in the study (response rate: 77.1%). Of these, 278 (69.3%) were female. A positive attitude towards research was reported by 43.9% of the students. No statistically significant differences were observed between genders with regards to attitudes towards and available resources for research (P = 0.500 and 0.200, respectively). Clinical students had a significantly more positive attitude towards research compared to preclinical students (P = 0.007). Only 26.4% of the respondents believed that they had adequate resources/opportunities for research. According to the students, perceived barriers to undertaking research included time constraints (n = 200; 49.9%), lack of research mentors (n = 95; 23.7%), lack of formal research methodology training (n = 170; 42.4%) and difficulties in conducting literature searches (n = 145; 36.2%). Conclusion: Less than half of the surveyed Saudi Arabian medical students had a positive attitude towards health research. Medical education policies should aim to counteract the barriers identified in this study. PMID:26909216

    Interest in the evolution and maintenance of personality is burgeoning. Individuals of diverse animal species differ in their aggressiveness, fearfulness, sociability and activity. Strong trade-offs, mutation-selection balance, spatio-temporal fluctuations in selection, frequency dependence and good-genes mate choice are invoked to explain heritable personality variation, yet for continuous behavioural traits, it remains unclear which selective force is likely to maintain distinct polymorphisms. Using a model of trust and cooperation, we show how allowing individuals to monitor each other's cooperative tendencies, at a cost, can select for heritable polymorphisms in trustworthiness. This variation, in turn, favours costly 'social awareness' in some individuals. Feedback of this sort can explain the individual differences in trust and trustworthiness so often documented by economists in experimental public goods games across a range of cultures. Our work adds to growing evidence that evolutionary game theorists can no longer afford to ignore the importance of real world inter-individual variation in their models. PMID:18957369

    Purpose This study provides descriptive epidemiological data, such as the percentage of cases diagnosed, crude incidence rate (CIR), and age-standardized incidence rate (ASIR) of ovarian cancer in Saudi Arabia from 2001–2008. Patients and methods A retrospective descriptive epidemiological analysis of all ovarian cancer cases recorded in the Saudi Cancer Registry (SCR) from January 2001–December 2008 was performed. The data were analyzed using descriptive statistics, analysis of variance tests, Poisson regression, and simple linear modeling. Results A total of 991 ovarian cancer cases were recorded in the SCR from January 2001–December 2008. The region of Riyadh had the highest overall ASIR at 3.3 cases per 100,000 women, followed by the Jouf and Asir regions at 3.13 and 2.96 cases per 100,000 women. However, Hail and Jazan had the lowest rates at 1.4 and 0.6 cases per 100,000 women, respectively. Compared to Jazan, the incidence rate ratio for the number of ovarian cancer cases was significantly higher (P<0.001) in the Makkah region at 6.4 (95% confidence interval [CI]: 4.13–9.83), followed by Riyadh at 6.3 (95% CI: 4.10–9.82), and the eastern region of Saudi Arabia at 4.52 (95% CI: 2.93–6.98). The predicted annual CIR and ASIR for ovarian cancer in Saudi Arabia could be defined by the equations 0.9 + (0.07× years) and 1.71 + (0.09× years), respectively. Conclusion We observed a slight increase in the CIRs and ASIRs for ovarian cancer in Saudi Arabia from 2001–2008. Riyadh, Jouf, and Asir had the highest overall ASIR, while Jazan and Hail had the lowest rates. Makkah, Riyadh, and the eastern region of Saudi Arabia had the highest incidence rate ratio for the number of ovarian cancer cases. Further analytical studies are required to determine the potential risk factors of ovarian cancer among Saudi women. PMID:25028565

    Dengue fever (DF) is the most serious mosquito-borne viral disease worldwide. DF is an acute febrile illness caused by Aedes aegypti and Aedes albopictus, which are endemic in certain cities of Saudi Arabia, such as Jeddah and Makkah (Mecca). An online literature search was conducted using relevant keywords to retrieve DF studies conducted in Saudi Arabia. Forty-five articles were identified initially. After screening for exclusion and retrieving full texts, a total of 10 articles were used for this review. Four studies were cross-sectional, and three observed a seroprevalence ranging from 31.7% to 56.9%, either among clinically suspected cases or among patients visiting the hospital for other reasons. Evidence extracted from risk factors and distribution studies indicated that young males are commonly affected. Fever, vomiting, thrombocytopenia and leukopoenia were the common features of the three studies related to clinical presentation of DF. One cross-sectional study concerning an educational program for DF demonstrated that a positive family history of DF, literate mothers, and age over 17 years were the predictors of a high DF knowledge score. However, the paucity of large epidemiological studies limits the generalizability of such evidence. Future studies in Saudi Arabia should focus upon the expansion of DF to other cities in the Kingdom. Larger epidemiological studies are needed for estimating the true burden and incidence of DF in the Saudi population, as they are limited to seroprevalence among clinically suspected cases and hospital-based patients.

    AIM: To identify the seroprevalence of celiac disease among healthy Saudi adolescents. METHODS: Between December 2007 and January 2008, healthy students from the 10th to 12th grades were randomly selected from three regions in Saudi Arabia. These regions included the following: (1) Aseer region, with a student population of 25512; (2) Madinah, with a student population of 23852; and (3) Al-Qaseem, with a student population of 16067. Demographic data were recorded, and a venous blood sample (5-10 mL) was taken from each student. The blood samples were tested for immunoglobulin A and immunoglobulin G endomysial antibodies (EMA) by indirect immunofluorescence. RESULTS: In total, 1167 students (614 males and 553 females) from these three regions were randomly selected. The majority of the study population was classified as lower middle class (82.7%). There were 26 (2.2%) students who had a positive anti-EMA test, including 17 females (3.1%) and 9 males (1.5%). Al-Qaseem region had the highest celiac disease prevalence among the three studied regions in Saudi Arabia (3.1%). The prevalence by region was as follows: Aseer 2.1% (10/479), Madinah 1.8% (8/436), and Al-Qaseem 3.2% (8/252). The prevalence in Madinah was significantly lower than the prevalence in Aseer and Al-Qaseem (P = 0.02). CONCLUSION: Our data suggest celiac disease prevalence might be one of the highest in the world. Further studies are needed to determine the real prevalence. PMID:23613632

    Medico-legal tasks are not exclusive to forensic medical experts -any physician may face medico-legal issues in his career. Hence, the practice of medicine requires education in legal issues. In Saudi Arabia, there are 30 universities with medical colleges, but we do not know how they teach undergraduate forensic medicine and medico-legal issues. The aim of this study was to discover undergraduate training courses in forensic medicine in Saudi universities. We conducted a cross-sectional study involving all colleges of medicine in Saudi Arabia. A structured, self-administered questionnaire containing 13 items relating to the undergraduate forensic medicine course was distributed. Out of a total of 30 universities, 27 universities responded. Of these 27 universities, 16 (59.26%) teach forensic medicine to undergraduate medical students, and 11 (40.74%) do not teach forensic medicine in their undergraduate curriculum. Of the 27 universities that responded, none has a department of forensic medicine. Eleven universities that do not teach forensic medicine have no forensic medicine unit/division or faculty at all. Forensic medicine belongs to the pathology department in 11 universities, while it belongs to different departments in five universities. There is variation in teaching methods, years where the course is taught and length of the course. Practical and morgue visits take place in 7/16 (43.8%) universities, while 9/16 (56.3%) universities only teach the theoretical aspects of forensic medicine. All 16 universities teach forensic medicine only to medical students and do not teach it to students in other colleges such as dentistry and nursing. PMID:27354384

    Teucrium (Lamiaceae) is a large and polymorphic genus distributed mainly in Europe, North Africa and in the temperate parts of Asia. In this study, the anatomical features of the leaf and stem of Teucrium polium are investigated. Teucrium has 19 taxa in Iran, which mainly grow in the Irano-Turanian region between 700 and 2000 m above sea level. T. polium belonging to sect. Polium, is a perennial herb growing on Lorestan province. The leaves clearly exhibit xeromorphy due to features such as thick cuticle layer, thick outer epidermal cell wall, high density of trichomes and thick palisade layer of the mesophyll. Anatomical studies on T. polium revealed that the stem shares the general characteristics of the Labiatae family. The aim of our approach was to study the morphological and taxonomical parameters for T. polium in Saudi Arabia. The results of this study showed that there was no influence of environment on the structure of stomata and trichomes as studying species with T . polium. In conclusion our study shows we have studied the geographical distribution of the species in Saudi Arabia and in the world. PMID:25737650

    Objectives Menopause is associated with somatic, vasomotor, psychological, and sexual complaints that may affect quality of life. We determined the prevalence and severity of menopausal symptoms and their impact on the quality of life among Saudi women visiting primary care centers in Riyadh, Saudi Arabia. Methods A cross-sectional study was conducted from October to November 2010. In total, 119 women aged 45–60 years were randomly interviewed using a questionnaire. Participants were divided into three categories: premenopausal (n=31), perimenopausal (n=49), and postmenopausal (n=39). The Menopause Rating Scale (MRS) assessed the prevalence and severity of eleven menopausal symptoms. Mean scores of menopausal categories were compared for different symptoms. Results The mean age at menopause was 48.3±3 years (median, 49 years). The symptoms reported to be most prevalent were joint and muscle pain (80.7%), physical and mental exhaustion (64.7%), and hot flushes and sweating (47.1%). Somatic and psychological symptoms were highly prevalent in perimenopausal women compared to other groups. The mean overall quality-of-life score was higher in perimenopausal women, while the total MRS score indicated that the symptoms were mild in severity (MRS <9). Conclusion The prevalence of menopausal symptoms was comparable to previous studies in Asian women; however, the prevalence of classic symptoms of hot flushes and night sweats was lower than reported in Western studies. Saudi women reported an MRS score indicating milder severity of symptoms, reflecting better quality of life and ability to cope with climacteric symptoms. PMID:26170720

    We assessed the vulnerability of the native Mediterranean pond turtle to encroachment by the invasive red-eared slider in southern Spain. We first obtained an ecogeographical favourability model for the Mediterranean pond turtle. We then modelled the presence/absence of the red-eared slider in the Mediterranean pond turtle range and obtained an encroachment favourability model. We also obtained a favourability model for the red-eared slider using the ecogeographical favourability for the Mediterranean pond turtle as a predictor. When favourability for the Mediterranean pond turtle was high, favourability for the red-eared slider was low, suggesting that in these areas the Mediterranean pond turtle may resist encroachment by the red-eared slider. We also calculated favourability overlap between the two species, which is their simultaneous favourability. Grids with low overlap had higher favourability values for the Mediterranean pond turtle and, consequently, were of lesser conservation concern. A few grids had high values for both species, being potentially suitable for coexistence. Grids with intermediate overlap had similar intermediate favourability values for both species and were therefore areas where the Mediterranean pond turtle was more vulnerable to encroachment by the red-eared slider. We mapped the favourability overlap to provide a map of vulnerability of the Mediterranean pond turtle to encroachment by the red-eared slider. PMID:24719577

    Objectives: To compare the performance of 3 commonly used 25-hydroxyvitamin D (25-OHD) assays among a sample of the Saudi population. Methods: This cross-sectional study was carried out between January 2011 and December 2012 at King Fahd Hospital of the University, Al-Khobar, Saudi Arabia. After informed consent, blood samples for measurement of 25-OHD level was extracted from 200 adults. The vitamin D level of each individual were determined using chemiluminescence immunoassay (CLIA), radio-immuno assay (RIA), and liquid chromatography-tandem mass spectrometry (LC-MS/MS) assay. Assays were also compared through commonly used cut-points for classification of vitamin D deficiency. Bias between assays was evaluated using Bland-Altman plots. Results: The average age of patients was 45.7±16.1 years. A significant difference between the assays was found. The mean 25-OHD levels were highest for the LC-MS/MS (21.65 ng/mL, 95% CI 19.74-23.56), intermediate for RIA (16.607 ng/mL, 95% CI 14.87-18.32), and lowest for CLIA method (13.864 ng/mL, 95% CI 12.109-15.618). Using 30 ng/mL as a cutoff value, only 6% was found to have normal levels of 25-OHD using CLIA, 9% using RIA, and 22% using LC-MS/MS. Conclusion: Levels of 25-OHD and the prevalence of vitamin D deficiency are dependent on the assay used. The reported high prevalence of hypovitaminosis D among the Saudi population can be partially explained by the use of assays that underestimate vitamin D levels. PMID:25316470

    Skin lipids play an important role in the regulation of cutaneous water loss (CWL). Earlier studies have shown that Saudi desert birds exhibit a tendency of reduced CWL than birds from temperate environment due to adaptive changes in composition of their skin lipids. In this study, we used thin-layer chromatography (TLC) for separation and detection of non-polar and polar lipids from the skin of six bird species including sooty gull, brown booby, house sparrow, Arabian waxbill, sand partridge, and laughing dove. The lipids were separated and detected on Silica gel G coated TLC plates and quantified by using densitometric image analysis. Rf values of the non-polar lipids were as follows: cholesterol (0.29), free fatty acids (0.58), triacylglycerol (0.69), fatty acids methyl esters (0.84) and cholesterol ester (0.97). Rf values for the polar lipids were: cerebroside (0.42), ceramide (0.55) and cholesterol (0.73). The results showed the abundance of fatty acids methyl esters (47.75-60.46%) followed by triacylglycerol (12.69-24.14%). The remaining lipid compositions were as follows: cholesterol (4.09-13.18%), ceramide (2.18-13.27%), and cerebroside (2.53-12.81%). In conclusion, our findings showed that TLC is a simple and sensitive method for the separation and quantification of skin lipids. We also reported a new protocol for lipid extraction using the zirconia beads for efficient disruption of skin tissues. This study will help us better understand the role of skin lipids in adaptive physiology towards adverse climatic conditions. PMID:24600311

The results showed the abundance of fatty acids methyl esters (47.75–60.46%) followed by triacylglycerol (12.69–24.14%). The remaining lipid compositions were as follows: cholesterol (4.09–13.18%), ceramide (2.18–13.27%), and cerebroside (2.53–12.81%). In conclusion, our findings showed that TLC is a simple and sensitive method for the separation and quantification of skin lipids. We also reported a new protocol for lipid extraction using the zirconia beads for efficient disruption of skin tissues. This study will help us better understand the role of skin lipids in adaptive physiology towards adverse climatic conditions. PMID:24600311

    Introduction Rift Valley fever (RVF) is an emerging viral zoonosis that impacts human and animal health. It is transmitted from animals to humans directly through exposure to blood, body fluids, or tissues of infected animals or via mosquito bites. The disease is endemic to Africa but has recently spread to Saudi Arabia and Yemen. Our aim was to compare two major outbreaks of RVF in Saudi Arabia (2000) and Sudan (2007) from a One Health perspective. Methods Using the terms ‘Saudi Arabia’, ‘Sudan’, and ‘RVF’, articles were identified by searching PubMed, Google Scholar, and web pages of international organizations as well as local sources in Saudi Arabia and Sudan. Results The outbreak in Saudi Arabia caused 883 human cases, with a case fatality rate of 14% and more than 40,000 dead sheep and goats. In Sudan, 698 human cases of RVF were recognized (case fatality, 31.5%), but no records of affected animals were available. The ecology and environment of the affected areas were similar with irrigation canals and excessive rains providing an attractive habitat for mosquito vectors to multiply. The outbreaks resulted in livestock trade bans leading to a vast economic impact on the animal market in the two countries. The surveillance system in Sudan showed a lack of data management and communication between the regional and federal health authorities, while in Saudi Arabia which is the stronger economy, better capacity and contingency plans resulted in efficient countermeasures. Studies of the epidemiology and vectors were also performed in Saudi Arabia, while in Sudan these issues were only partly studied. Conclusion We conclude that a One Health approach is the best option to mitigate outbreaks of RVF. Collaboration between veterinary, health, and environmental authorities both on national and regional levels is needed. PMID:24505511

    Between January 1980 and December 1982, 183 patients with histologically confirmed carcinoma of the esophagus who were referred to a tertiary referral hospital were studied. Thirty-two (17%) patients were referred from Gassim Region at the north central part of Saudi Arabia. In contrast, only 5% of total cancer patient referrals were from this area. A case-control study showed a significant regional difference within Saudi Arabia and the most referrals from Gassim area. A prospective case-control study showed persistently high numbers of referrals from that region during 1983-1987. When patients from Gassim Region were compared with those referred from other locations, no statistical differences were noted between the two groups except for the source of drinking water. Water analysis from Gassim area showed a high solid content with elevated levels of calcium, magnesium, and to a lesser extent, chromium iron, cadmium, and cobalt. Traces of petroleum oil were found in five of six water samples from Gassim during 1983, compared with 3 of 49 samples from other areas. Mutagenicity tests on water specimens form Gassim Region indicated the presence of possible carcinogens. It is being suggested that the high prevalence of esophageal cancer in this region may be related to contamination of water by impurities such as petroleum oils. Malnutrition, particularly vitamin A deficiency, as well as other factors may have promoted such malignancies.

    In the last two decades, vehicular traffic increased spectacularly in Saudi Arabia, from 243,000 registered motor vehicles in 1973 to over 5 million at present. All these vehicles use leaded gasoline, one of the major sources of lead contamination in the ambient air and dusts in the cities. To evaluate the impact of this high level of environmental lead, scalp hair of 200 school boys, aged 6-8 years, from each of the two cities (Makkah in the western region and Riyadh in the central region) and two Village Groups (one around Makkah city and the other around Riyadh city) were analyzed in this study for lead concentrations. Makkah is one of the oldest and most densely populated cities with congested housing and narrow winding streets. Riyadh on the other hand is the newly developing, planned capital city of Saudi Arabia. The Village Groups were chosen so as to reflect a control environment away from heavy traffic and industrial activity. The usefulness of hair as an important biopsy material for environmental pollution studies has been demonstrated in a large number of studies. Effect of lead on the central nervous system of the children may result in mental retardation and even death in case of acute encephalopathy.

    The present study was conducted to investigate the prevalence of musculoskeletal disorders and eye and vision complaints among the computer users of King Abdulaziz University (KAU), Saudi Arabian Airlines (SAUDIA), and Saudi Telecom Company (STC). Stratified random samples of the work stations and operators at each of the studied institutions were selected and the ergonomics of the work stations were assessed and the operators' health complaints were investigated. The average ergonomic score of the studied work station at STC, KAU, and SAUDIA was 81.5%, 73.3%, and 70.3, respectively. Most of the examined operators use computers daily for ≤ 7 hours, yet they had some average incidences of general complaints (e.g., headache, body fatigue, and lack of concentration) and relatively high level of incidences of eye and vision complaints and musculoskeletal complaints. The incidences of the complaints have been found to increase with the (a) decrease in work station ergonomic score, (b) progress of age and duration of employment, (c) smoking, (d) use of computers, (e) lack of work satisfaction, and (f) history of operators' previous ailments. It has been recommended to improve the ergonomics of the work stations, set up training programs, and conduct preplacement and periodical examinations for operators. PMID:25383379

    The authors studied the landscape components that favour the occurrence of anthrax in the Flooding Pampa grasslands (Buenos Aires province, Argentina). They made spatial locations of anthrax outbreaks diagnosed by registered veterinary laboratories in the study area's zone of influence. As variables for study, they differentiated areas that are flooded for 20% of the time or more from primary and secondary runoff channels. They also identified areas with low-productivity pasture. Logistic regression analysis of farm populations revealed that landscape components favouring the occurrence of anthrax outbreaks are shared runoff channels (odds ratio (OR) = 2.3; confidence interval (CI) = 1.2; 4.7) and > or = 40% low-productivity pasture (OR = 5.4; CI = 3.5; 8.3). Contrary to initial assumptions, susceptibility to flooding was not a significant variable (OR = 1.1; CI = 0.5; 2.1). The authors concluded that the first step in decision-making and ensuring more efficient implementation of future anthrax control and eradication plans was to identify risk variables. PMID:22435200

    Background/Aim: Epidemiological studies of celiac disease (CD) among Saudi children have been performed only within some groups who are at a high risk of developing CD. The aim of this study was to determine the prevalence of CD among symptom-free children from the public schools of the military campus of National Guard in the Eastern Province of Saudi Arabia. Patients and Methods: Between 2012 and 2014, serum samples were collected from 1141 students (age 6–18 years) attending nine public schools of the military campus of National Guard in the Eastern Province of Saudi Arabia. Participants were screened for CD by testing for anti-tissue transglutaminase IgA (IgA-tTG) and IgG antibodies (IgG-tTG). Small intestinal biopsy was offered to all participants who tested positive for IgA-tTG [IgA-tTG >20 relative units (RU)/ml]. Results: Of the 1141 participants, 32 were IgA-tTG positive. Thus, the estimated serology-positive prevalence was 3%. An intestinal biopsy was performed in 10 of the participants with antibody positivity. The biopsy findings of all 10 children were consistent with CD. Thus, the estimated biopsy-confirmed prevalence was about 1%. Conclusions: The prevalence of CD was estimated to be about 1% among symptom-free children from the public schools of the military campus of National Guard in the Eastern Province of Saudi Arabia.

    Background. Vitamin D deficiency is a global health problem. Some evidences indicate its association with metabolic syndrome, type II diabetes, and cardiovascular diseases. In the current study we aim to study the association of vitamin D level and indicators of adiposity in young Saudi females. Subjects and Methods. 87 young healthy Saudi females were recruited from University of Dammam, Dammam, Saudi Arabia. Each subject filled vitamin D questionnaire and had exercise stress test to determine VO2 peak. Body weight, BMI, waist and hip circumference, and ratios were determined. Blood was analyzed for 25-OH vitamin D, glucose, triglycerides, total cholesterol, and differential cholesterol. Results. 25-OH vitamin D/body weight was negatively associated with waist circumference and waist/stature ratio. No significant difference was found between the groups of BMI with regard to the data of questionnaire or 25-OH vitamin D/body weight. Obese and overweight subjects had lower VO2 peak. Conclusion. In young Saudi females we found that the relative value of vitamin D to body weight is a better indicator of vitamin D status particularly in obese subjects and it is negatively associated with adiposity measures of waist circumference and waist/stature ratio.

    Hepatitis C virus (HCV) infection is a major health problem recognized globally. HCV is a common cause of liver fibrosis that may lead to liver cirrhosis or hepatocellular carcinoma. The aim of this study was to estimate the prevalence of HCV infection and genotyping among Egyptian and Saudi Arabian chronic patients using different molecular techniques. HCV RNA viral load was assessed by real-time polymerase chain reaction (RT-PCR) technology. For HCV genotyping, RT-PCR hybridization fluorescence-based method and reverse hybridization line probe assay (INNO-LiPA) were used. A total of 40 anti-HCV-positive patients with chronic hepatitis C were examined for HCV RNA, genotyping, and different laboratory investigations. In the present study, HCV genotypes 4, mixed 4.1b, and 1 were detected in patients of both countries, while genotype 2 was only detected in Saudi Arabian patients. Genotyping methods for HCV showed no difference in the classification at the genotype level. With regard to HCV subtypes, INNO-LiPA assay was a reliable test in HCV genotyping for the detection of major genotypes and subtypes, while RT-PCR-based assay was a good test at the genotype level only. HCV genotype 4 was found to be the predominant genotype among Egyptian and Saudi Arabian chronic patients. In conclusion, data analysis for detecting and genotyping HCV was an important factor for understanding the epidemiology and treatment strategies of HCV among Egyptian and Saudi Arabian chronic patients.

    Objectives: To determine the prevalence of habitual snoring among a sample of middle-aged Saudi adults, and its potential predictors. Methods: A cross-sectional study was conducted from March 2013 until June 2013 in randomly selected Saudi Schools in Jeddah, Kingdom of Saudi Arabia. The enrolled subjects were 2682 school employees (aged 30-60 years, 52.1% females) who were randomly selected and interviewed. The questionnaire used for the interview included: the Wisconsin Sleep Questionnaire to assess for snoring, medical history, and socio-demographic data. Anthropometric measurements and blood pressure readings were recorded using standard methods. Results: Forty percent of the 2682 enrolled subjects were snorers: 23.5% were habitual snorers, 16.6% were moderate snorers, and 59.9%, were non-snorers. A multivariate analysis revealed that independent predictors of snoring were ageing, male gender, daytime sleepiness, hypertension, family history of both snoring and obstructive sleep apnea, water-pipe smoking, and consanguinity. Conclusion: This study shows that snoring is a common condition among the Saudi population. Previously reported risk factors were reemphasized but consanguinity was identified as a new independent predictive risk factor of snoring. Exploring snoring history should be part of the clinical evaluation. PMID:26219441

    Objectives: To determine the prevalence of Chlamydia trachomatis (C. trachomatis) infection among Saudi women, its clinical presentation, and its association to infertility. Methods: This study was conducted between October 2012 and July 2013 at King Khalid University Hospital and King Abdulaziz University Hospital, Riyadh, Kingdom of Saudi Arabia. Female patients aged between 19 and 46 years old with infertility problems seen at both hospitals were recruited to join the study. A separate group of female patients without infertility problems was also recruited from both hospitals to serve as controls for the study. Endocervical swabs were collected from both groups of patients, and samples were analyzed using real time polymerase chain reaction. Results: There was a statistically significantly greater prevalence of C. trachomatis infection in infertile women (n=8, 8.0%) compared with the fertile group of women (n=1, 1.0%). The C. trachomatis infection was significantly correlated to infertility. Conclusion: A significant association between infertility and increased prevalence of C. trachomatis infection is shown in this study, thus, we suggest that screening for Chlamydial infection to be part of the routine investigation for infertility.

    Oro-facial pain (OFP) and temporomandibular disorders (TMD) in children and adolescents are a growing problem. To meet patients' healthcare needs, professionals must perform their work intuitively and with quality. Therefore, a high degree of professional knowledge is necessary. To investigate the professional knowledge regarding OFP/TMD in children and adolescents among Swedish and Saudi Arabian dental and medical specialists compared with Swedish OFP specialists. One questionnaire including the four domains Chronic pain and behaviour; Aetiology; Diagnosis and classification; Treatment and prognosis was distributed to 383 potential participants, that is physicians and dentists in Sweden and Saudi Arabia. The Swedish OFP/TMD specialists were used as a reference group. The response rates from Sweden and Saudi Arabia were 49% and 86%, respectively. The degree of agreement was highest in the domain Chronic pain and behaviour, especially for the Swedish groups. Regarding the other three domains, the agreement was modest to poor. In general, Swedish groups showed a higher agreement with Swedish OFP/TMD specialists than Saudi Arabian groups. This study shows that professional knowledge regarding OFP/TMD in children and adolescents is limited among Swedish and Saudi Arabian dental and medical professionals compared to Swedish OFP/TMD specialists. In Swedish groups, the professional knowledge is more accurate than in the corresponding Saudi Arabian. With these results in mind, and the frequent prevalence of OFP/TMD in children and adolescents, one can draw the conclusion that there is a need for modern medical education regarding OFP/TMD among both physicians and dentists, especially in Saudi Arabia.

    The current study was aimed to assess Saudi school students’ knowledge, attitude and practice about medicines. A pretested self-administered questionnaire was used anonymously among 15–20 year-old adolescents attending tertiary schools in Taif City, KSA. A total of 1022 students completed the questionnaires. Only 15.4% of the respondents knew the medicines’ uses. Most of the students 79.6% affirmed that they used to take medicines after consulting physicians, and 45.1% of the students thought that tablet size affects the medicine’s efficacy. More than half of the students knew that high temperatures affect the efficacy of medicines, there was a significant difference between rural and urban areas (P = 0.005). Physicians (50.6%) and community pharmacists (15.7%), were the main students’ reliable sources of information about medicines. The majority of the students 70.5% were interested in learning more about medicines. The younger students ⩽18 years wish to learn more than the older ones (P < 0.014). The study showed that Saudi school students aged 15–20 years old have poor knowledge, misconception and negative attitudes about medicines. Low level of knowledge may expose adolescents to health-related problems. Educational efforts are important to improve students’ practice toward medicines. PMID:25061406

    Objectives: To assess knowledge, attitude, and barriers about emergency contraception (EC) among married women of child bearing age. Methods: A quantitative cross-sectional study was conducted over a 6-month period, commencing in March 2013 at Family Practice Clinics of King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia. Data was collected using a structured pretested questionnaire and analyzed using SPSS version 21.0 statistical software. Result: A total of 242 women were enrolled in the study. Only 6.2% (15/242) had some knowledge of EC and of these only two had ever used it. Health care professionals were the least reported source of EC information (6.6%, n=1). Majority (73.3%) had negative attitude toward EC being available over-the-counter without a prescription. The most common barriers to using EC were concerns about possible health effects. Only two women (13.3%) considered religious belief as a major hindrance to its use. Conclusion: Awareness of emergency contraception is very low among women of Saudi Arabia. Health care professionals were the least reported source of information, which is a cause for concern. Our findings reveal an urgent need to educate women about EC, keeping in view the social norms and the Islamic values. PMID:26870124

    Puberty is the gradual transition period between childhood and adulthood. Many factors may contribute to the onset of puberty. The objective of the study was to determine the age of onset of secondary pubertal characteristics among Saudi Arabian girls. A cross-sectional study was conducted using a cluster sample design. Seven hundred and twenty-five schoolgirls between the ages of 6 and 16 years from diverse socioeconomic levels were included. During physical examinations, the height and weight of the girls were recorded, and the stages of breast and pubic hair development were determined according to Tanner stages; axillary hair development was determined according to modified stages. The median age at Tanner stage 2 for breast and pubic hair development was 10 years. The median age at stage 2 in modified scales for axillary hair development was 12 years. In conclusion, the median age of the onset of breast development at Tanner stage 2 for Saudi girls in Riyadh is lower than what has been reported in some countries in Europe, South Africa, Turkey and India but similar to girls in Hong Kong, China and white girls in the USA, which may support secular trends of an earlier onset of puberty.

    Background/Aims: The aim of this study was to investigate colorectal cancer (CRC) awareness in healthy individuals in Saudi Arabia in order to identify segments of the population that would most benefit from targeted education programs. Setting and Design: Survey/questionnaire. Patients and Methods: Random, healthy individuals from Riyadh, Saudi Arabia, were approached to participate in a 10-question multiple choice survey about CRC. Data were analyzed by demographic criteria, including age, gender, marital status, and level of education, to determine if members of these groups displayed differential knowledge. Statistical Analysis: Differences in responses by demographic data were analyzed using Pearson's Chi-square test. A P < 0.05 was considered statistically significant. Results: In total, 1070 participants completed the survey. Most respondents believe that screening for colon cancer should begin at symptom onset (42.9%). Less than 20% of all respondents believe that polyps are a risk factor for CRC, which varied significantly according to level of education; however, even the most educated answered correctly less than 50% of the time. Similarly, only 34.8% of all respondents knew that a family history of CRC imparted a personal risk for CRC. Conclusions: Although older individuals and those with higher education tended to answer questions correctly more often, there were some misconceptions regarding universally accepted screening protocols, symptoms, and general understanding of CRC in Saudi Arabia. A national education/screening program in Saudi Arabia is recommended to improve CRC knowledge. PMID:25843193

    Objectives: To investigate the association between stress, shift work, and eating behavior among non-Saudi female nurses working in Central Saudi Arabia. Methods: A sample of 395 non-Saudi female nurses from 2 major hospitals in Riyadh, Kingdom of Saudi Arabia participated in this cross-sectional study. The nurses completed a questionnaire from November 2013 to January 2014 that included items relating to stress and eating behavior using the Dutch Eating Behavior Questionnaire (DEBQ). The questionnaire also contained items pertaining to socio-demographic data, body mass index, shift work, and hours worked per week. Results: For all eating styles, stress, and shift duty influenced the amount of food nurses consumed, but was more significant under a restrained eating style. Under this eating style, a significantly higher percentage of nurses reported eating more fast food, snacks, and binging, while fruits and vegetables were the least likely to be eaten under stress. High stressed nurses were more likely to present with abnormal restrained eating (odds ratio [OR]=1.52, p=0.004), emotional (OR=1.24; p=0.001), and external (OR=1.21; p=0.001) DEBQ scores. Working nighttime shift duty was positively associated with restrained eating (OR=1.53; p=0.029) and emotional eating (OR=1.24; p=0.001), but negatively associated with external eating (OR=0.45; p=0.001). Conclusion: Our findings suggest that stress and shift duty were associated with eating habits. PMID:26837403

    Objectives: To assess the prevalence of pseudoexfoliation syndrome (PEX), and associated ophthalmic complications among Saudi patients. Methods: The prevalence of PEX and associated ocular co-morbidities were determined among the Saudi patients visiting the Primary Care Clinic of Prince Sultan Military Medical City, Riyadh, Kingdom of Saudi Arabia, between January 2009 and January 2010. A total of 1967 patients were examined biomicoscopically by ophthalmologists to determine the presence of PEX and associated ocular complications. Results: Sixty-nine of the 1967 examined patients (3.5%) showed the presence of PEX with no significant gender difference. There was an age dependent increase in the prevalence of PEX after the age of 50 years. Pseudoexfoliation syndrome was associated with higher intraocular pressure, cataract, and poor vision. There was no significant difference in the prevalence of PEX in male and female Saudi patients. Conclusion: Pseudoexfoliation syndrome is an age-related disorder, and its prevalence increases with age. Further larger population based studies are warranted to assess the prevalence of PEX and associated risk factors. PMID:25630014

    Balancing groundwater depletion, socioeconomic development and food security in Saudi Arabia will require policy that promotes expansion of unconventional freshwater supply options, such as wastewater recycling and desalination. As these processes consume more electricity than conventional freshwater supply technologies, Saudi Arabia's electricity system is vulnerable to groundwater conservation policy. This paper examines strategies for adapting to long-term groundwater constraints in Saudi Arabia's freshwater and electricity supply sectors with an integrated modeling framework. The approach combines electricity and freshwater supply planning models across provinces to provide an improved representation of coupled infrastructure systems. The tool is applied to study the interaction between policy aimed at a complete phase-out of nonrenewable groundwater extraction and concurrent policy aimed at achieving deep reductions in electricity sector carbon emissions. We find that transitioning away from nonrenewable groundwater use by the year 2050 could increase electricity demand by more than 40% relative to 2010 conditions, and require investments similar to strategies aimed at transitioning away from fossil fuels in the electricity sector. Higher electricity demands under groundwater constraints reduce flexibility of supply side options in the electricity sector to limit carbon emissions, making it more expensive to fulfill climate sustainability objectives. The results of this analysis underscore the importance of integrated long-term planning approaches for Saudi Arabia's electricity and freshwater supply systems. PMID:26807884

    The relationship between the Mediterranean 500-hPa storm tracks and wet season (November-April) rainfall over Saudi Arabia is investigated. The analysis is based on the application of an objective tracking scheme to the 6-hourly 500-hPa geopotential height ERA-Interim dataset (0.75° × 0.75°) for the period 1979-2012. The resulting tracks are then associated with the ERA-Interim rainfall events over Saudi Arabia. The association procedure showed that 34 % of the tracks are related to about 70 % of the rainfall. These associated tracks are used to construct climatology. A climatology of these storm tracks revealed that the eastern Mediterranean region is the preferred location for cyclogenesis with a maximum in the southwest parts of the Black Sea. The study also examined the mean radius, average intensity and average depth of the storms. The number of tracks in winter (December-February) is about 60 % of the total number which confirms the major contribution of the Mediterranean storms to rainfall over Saudi Arabia. A significant negative trend was found for storm cyclogenesis over the central Mediterranean, and the Black sea. A significant trend decrease in track density is observed over most of the northern parts of Saudi Arabia. The peaks of storm activities are observed in December and January in 1996, 1997 and 2009. Storm activity generally declines after 2000, especially in the second half of the wet season months (February-April).

    Background Saudi Arabia has passed through lifestyle changes toward unhealthy dietary patterns such as high fast food consumption. Adolescents and young adults, particularly girls, are the main groups exposed to and affected by these adverse eating behaviors. Objective The aim of this study was to examine the trends of fast food consumption among adolescent and young adult Saudi girls living in Riyadh, and to compare between them. Design In a cross-sectional survey, 127 adolescent Saudi girls (13–18 years) and 69 young adult Saudi girls (19–29 years) were randomly recruited to participate in this study. Weight, height, waist circumference, and hip circumference were measured using standardized methods. Twenty-four-hour diet recall and a face-to-face interview food questionnaire were performed. Results Most of the participants had adequate intake of protein, riboflavin, iron, and sodium, but exhibited low intake for several other nutrients. Among study participants, 95.4% consume restaurants’ fast food and 79.1% eat fast food at least once weekly. Burgers and carbonated soft drinks were the main kinds of fast food meals and beverages usually eaten by girls. Adolescent girls who usually ate large portion sizes of fast food had significantly higher mean waist circumference and hip circumference. Participants eat fast food primarily for enjoying the delicious taste, followed by convenience. Restaurants’ hygiene and safety standards were the main concern regarding fast food for 62.2% of girls. Finally, international restaurants were preferable by participants to buy fast food compared with local restaurants (70.9% vs. 29.1%). Conclusion Our findings provide evidence on the high prevalence of fast food consumption among Saudi girls, suggesting an urgent need for community-based nutrition interventions that consider the trends of fast food consumption and targeted eating behaviors of adolescent and young adult girls.

    Background Breaking bad news (BBN) to parents whose newborn has a major disease is an ethical dilemma. In Saudi Arabia, BBN about newborns is performed according to the parental preferences that have been reported from non-Arabic/non-Islamic countries. Saudi mothers' preferences about BBN have not yet been studied. Therefore, we aimed to elicit the preferences of Saudi mothers about BBN concerning newborns. Methods We selected a convenience sample of 402 Saudi mothers, aged 18-50 years, who had no previous experience with BBN. We selected them via a simple number-randomization scheme from the premises of a level III Saudi hospital between October of 2009 and January of 2011. We used a hypothetical situation (BBN about trisomy 21) to elicit their preferences about BBN concerning newborns via a structured verbal questionnaire composed of 12 multiple-choice questions. We expressed their preferences as percentages (95% confidence interval), and we used the Kendall's W test (W) to assess the degree of agreement in preferences. Results The Saudi mothers preferred that BBN be conducted with both parents together (64% [60-69]), albeit with weak levels of agreement (W = 0.29). They showed moderate agreement in their preferences that BBN should be conducted early (79% [75-83], W = 0.48), in detail (81% [77-85], W = 0.52), in person (88% [85-91], W = 0.58), and in a quiet setting (86% [83-90], W = 0.53). With extremely weak agreement, they preferred to have a known person present for support during BBN (56% [51-61], W = 0.01), to have close bodily contact with their babies (66% [61-70], W = 0.10), and to have no another patients present (64% [59-68], W = 0.08). They showed moderate levels of agreement in their desires to detail, in advance, their preferences about process of BBN by giving a reversible, written informed consent that could be utilized for guidance, if needed (80% [76-84], W = 0.36). Conclusions In our experience, Saudi mothers' preferences about BBN concerning

    Al-Mostafa, Z. A.

    The atmospheric turbidity has been calculated and averaged for 29 places around the Kingdom of Saudi Arabia by using a nine years solar radiation data covering the period from 1971 to 1980. The turbidity values were found to range from 0.1 to 0.4, and the overall average of the turbidity was 0.281±0.056. The minimum value was in Sirr-Lasan (0.168±0.028) and the maximum value was 0.474±0.090 in Riyadh. The low value of the turbidity indicates that the sky of Sirr-Lasan (2100 meter above sea level) may be the clearest sky in the country if the turbidity is taken to be the main factor in preliminary site selection for astronomical observatory. Correlations between the turbidity and geographical coordinates have been investigated and have shown a weak relation between them. Also, seasonal variations studies have shown no significant distribution, which means that each station has its own trend. The low values of the turbidity indicate that the Saudi Arabian sky has relatively small disturbance in the atmosphere.

    Identifying the predictors of smoking in one of the top cigarette-consuming countries in the world is a vital step in smoking prevention. A cross-sectional study assessed the predictors of smoking in a cohort of male students in 3 universities in Saudi Arabia. A pre-tested, validated questionnaire was used to determine sociodemographic characteristics, academic performance, peers' smoking, and presence of a smoker within the family. Of the 337 participants, 30.9% were current smokers (smoked 1 or more cigarettes within the last 30 days). Lower academic performance (OR = 2.29, 95% CI: 1.02-5.17), peer smoking (OR = 4.14, 95% CI: 1.53-11.3) and presence of other smokers in the family (OR = 2.77, 95% CI: 1.37-5.64) were the significant predictors of smoking status identified using multiple logistic regression analysis. These findings highlight the influence of family and peer pressure in initiating cigarette use among the youth of Saudi Arabia. PMID:24673080

    This study focuses on the chemical analysis of the available brands of domestic bottled water in Riyadh City, Saudi Arabia. The distribution of the chemical constituents (major, minor, and trace elements) is determined and compared with the chemical content labeled on the bottles and with drinking water standards of Saudi Arabian, World Health Organization, and U.S. Environmental Protection Agency. The obtained results indicated that except for fluoride and bromate, the concentrations of dissolved salts, soluble cations and anions, nitrate, and trace elements of most bottled waters on sale were within the permissible limits set by standards used. On the other hand, the comparison between determined and reported label values recorded a substantial variation in some parameter values. Results indicated that more than 18 % of the sampled bottled waters exceeded the allowable limits for drinking water. Generated Piper diagrams revealed that the majority of investigated waters were sodium chloride-sulfate type; however, the hydrochemical modeling indicated that all water samples were undersaturated for anhydrite, gypsum, and halite.

    BACKGROUND: Pulmonary rehabilitation (PR) programs proven to be one of the most effective treatment options for respiratory diseases; yet, they are not well-established in hospitals in Saudi Arabia. AIM: To determine the main barriers for setting up PR programs in Saudi Arabia. METHODS: A cross-sectional study was conducted in the Eastern Province of Saudi Arabia. Health care providers involved in treatment of chronic obstructive pulmonary disease (COPD) patients were recruited from 22 general government hospitals. Data were collected using questionnaires: Full version if they had heard about PR before the study, and a short version if they had not heard about PR before. RESULTS: A total of 123 health care providers were recruited (physicians [n = 44], nurses [n = 49], and respiratory therapists/technicians [n = 30]). Only 3.2% of the recruited health care providers had heard about PR programs before. According to the health care providers, the main barriers for setting up PR programs were a lack of (1) hospital capacity (75.6%), (2) trained health care providers (72.4%), and (3) funds (48.0%). There were significant differences in barriers reported by the health care providers. Compared to physicians, nurses were more likely to nominate the PR costs as a barrier (18.0% vs. 38.8%; P < 0.05). CONCLUSION: There is a worrisome lack of knowledge regarding content and benefits of PR programs among Saudi health care providers treating COPD patients. These findings imply that improving awareness and increasing education of the health care providers regarding PR will be required before PR can be more widely implemented as an integral treatment modality for patients with COPD in Saudi Arabia.

  2. Incorporating the Delphi Technique to investigate renewable energy technology transfer in Saudi Arabia

    NASA Astrophysics Data System (ADS)

    Al-Otaibi, Nasir K.

    Saudi Arabia is a major oil-producing nation facing a rapidly-growing population, high unemployment, climate change, and the depletion of its natural resources, potentially including its oil supply. Technology transfer is regarded as a means to diversify countries' economies beyond their natural resources. This dissertation examined the opportunities and barriers to utilizing technology transfer successfully to build renewable energy resources in Saudi Arabia to diversify the economy beyond oil production. Examples of other developing countries that have successfully used technology transfer to transform their economies are explored, including Japan, Malayasia, and the United Arab Emirates. Brazil is presented as a detailed case study to illustrate its transition to an economy based to a much greater degree than before on renewable energy. Following a pilot study, the Delphi Method was used in this research to gather the opinions of a panel of technology transfer experts consisting of 10 heterogeneous members of different institutions in the Kingdom of Saudi Arabia, including aviation, telecommunication, oil industry, education, health systems, and military and governmental organizations. In three rounds of questioning, the experts identified Education, Dependence on Oil, and Manpower as the 3 most significant factors influencing the potential for success of renewable energy technology transfer for Saudi Arabia. Political factors were also rated toward the "Very Important" end of a Likert scale and were discussed as they impact Education, Oil Dependence, and Manpower. The experts' opinions are presented and interpreted. They form the basis for recommended future research and discussion of how in light of its political system and its dependence on oil, Saudi Arabia can realistically move forward on renewable energy technology transfer and secure its economic future.

  3. The Challenges Faced by New Science Teachers in Saudi Arabia

    Growing demand for science teachers in the Kingdom of Saudi Arabia, fed by increasing numbers of public school students, is forcing the Saudi government to attract, recruit and retain well-qualified science teachers. Beginning science teachers enter the educational profession with a massive fullfilment and satisfaction in their roles and positions as teachers to educating children in a science classroom. Nevertheless, teachers, over their early years of practice, encounter numerous challenges to provide the most effective science instruction. Therefore, the current study was aimed to identify academic and behavioral classroom challenges faced by science teachers in their first three years of teaching in the Kingdom of Saudi Arabia. In addition, new science teacher gender, school level and years of teaching experience differences in perceptions of the challenges that they encountered at work were analyzed. The present study also investigated various types of support that new science teachers may need to overcome academic and behavioral classroom challenges. In order to gain insights about ways to adequately support novice science teachers, it was important to examine new science teachers' beliefs, ideas and perceptions about effective science teaching. Three survey questionnaires were developed and distributed to teachers of both sexes who have been teaching science subjects, for less than three years, to elementary, middle and high school students in Al Jouf public schools. A total of 49 novice science teachers responded to the survey and 9 of them agreed to participate voluntarily in a face-to-face interview. Different statistical procedures and multiple qualitative methodologies were used to analyze the collected data. Findings suggested that the top three academic challenges faced by new science teachers were: poor quality of teacher preparation programs, absence of appropriate school equipment and facilities and lack of classroom materials and instructional

    This paper reports that foreign oil companies with concessions in northern Yemen have been drawn into a border dispute between Yemen and Saudi Arabia. At least six companies received letters from the Saudi government warning them that steps, as yet undefined, will be taken if exploration extends into disputed areas. A second territorial dispute also appears to be brewing in the region. Iran has ejected United Arab Emirates nationals from the island of Abu Musa in the Persian Gulf, which is jointly administered by Iran and Sharjah, one of the emirates. The U.A.E. government has reported the situation to the Gulf Cooperation Council, triggering a denial from Iran that anyone has been deported from the island.

    On Aug. 2, 1990, Iraqi forces invaded Kuwait and triggered one of the most severe crises in the world's oil supplies since World War II. Within a few days of the invasion, Iraqi and Kuwaiti oil exports were embargoed, and almost 4.6 million b/d oil of production was removed from world markets. This shortfall amounted to about 20% of total Organization of Petroleum Exporting Countries production at the time and could have proven disastrous to the world's industrial and financial well-being. However, there was no disruption to the major economies of the world. This paper reports that the primary reason for the cushioning of this impact was the massive expansion in production undertaken by Saudi Arabian Oil Co. (Saudi Aramco).

    Saudi Arabia is an arid desert country without rivers or sweet-water lakes. It does, however, have large amounts of ground water and seawater. These waters must be desalted by some means in order to make them potable. The most frequently used methods for that purpose are: multistage flash (MSF) evaporation, reverse osmosis (RO), and electrodialysis (ED). Because of rapid industrialization of the country, the demand for fresh water has been growing steadily. This, in turn, has resulted in a spectacular growth of the water-desalination industry. This paper discusses the availability and properties of the waters. It gives a detailed description of the major accomplishments and of the ongoing and future programs in the field of water desalination in Saudi Arabia. 14 references, 6 figures, 8 tables.

    Background During Ramadan fast, approximately one billion Muslims abstain from food and fluid between the hours of sunrise to sunset, and usually eat a large meal after sunset and another meal before sunrise. Many studies reported good health-related outcomes of fasting including weight loss. The objective of this study is to identify the local pattern of expenditure on food consumption, dietary habits during Ramadan and correlate that to self-reported weight gain after Ramadan in a group of families in Jeddah, Western Saudi Arabia. Methods A Cross-section study using a pre-designed questionnaire to identify the local pattern of expenditure on food consumption, dietary habits during Ramadan and correlate that to self-reported weight gain after Ramadan in a representative cohort of Saudis living in Jeddah. It was piloted on 173 nutrition students and administered by them to their families. Results A total of 173 Saudi families were interviewed. One out of 5 indicated that their expenditure increases during Ramadan. Approximately two thirds of the respondents (59.5%) reported weight gain after Ramadan. When asked about their perspective explanations for that: 40% attributed that to types of foods being rich in fat and carbohydrates particularly date in (Sunset meal) 97.7% and rice in (Dawn meal) 80.9%. One third (31.2%) indicated that it was due to relative lack of physical exercise in Ramadan and 14.5% referred that to increase in food consumption. Two thirds (65.2%) of those with increased expenditure reported weight gain. Conclusion Surprisingly weight gain and not weight loss was reported after Ramadan by Saudis which indicates timely needed life-style and dietary modification programs for a population which reports one of the highest prevalence rates of diabetes.

    Purpose This study describes the epidemiology of Middle East respiratory syndrome coronavirus (MERS-CoV) in Saudi Arabia. Patients and methods Epidemiological analysis was performed on data from all MERS-CoV cases recorded by the Saudi Ministry of Health between June 6, 2013 and May 14, 2014. The frequency of cases and deaths was calculated and adjusted by month, sex, age group, and region. The average monthly temperature and humidity of infected regions throughout the year was also calculated. Results A total of 425 cases were recorded over the study period. The highest number of cases and deaths occurred between April and May 2014. Disease occurrence among men (260 cases [62%]) was higher than in women (162 cases [38%]), and the case fatality rate was higher for men (52%) than for women (23%). In addition, those in the 45–59 years and ≥60 years age groups were most likely to be infected, and the case fatality rate for these people was higher than for other groups. The highest number of cases and deaths were reported in Riyadh (169 cases; 43 deaths), followed by Jeddah (156 cases; 36 deaths) and the Eastern Region (24 cases; 22 deaths). The highest case fatality rate was in the Eastern Region (92%), followed by Medinah (36%) and Najran (33%). MERS-CoV infection actively causes disease in environments with low relative humidity (<20%) and high temperature (15°C–35°C). Conclusion MERS-CoV is considered an epidemic in Saudi Arabia. The frequency of cases and deaths is higher among men than women, and those above 45 years of age are most affected. Low relative humidity and high temperature can enhance the spread of this disease in the entire population. Further analytical studies are required to determine the source and mode of infection in Saudi Arabia. PMID:25187734

    Objectives To evaluate the effectiveness of a pharmacist-led educational intervention to reduce the use of high-risk abbreviations (HRAs) by healthcare professionals. Design Quasi-experimental study consisting of a single group before-and-after study design. Setting A public emergency hospital in Mecca, Saudi Arabia. Participants 660 (preintervention) and then 498 (postintervention) handwritten physician orders, medication administration records (MRAs) and pharmacy dispensing sheets of 482 and 388 patients, respectively, from emergency wards, inpatient settings and the pharmacy department were reviewed. Intervention The intervention consisted of a series of interactive lectures delivered by an experienced clinical pharmacist to all hospital staff members and dissemination of educational tools (flash cards, printed list of HRAs, awareness posters) designed in line with the recommendations of the Institute for Safe Medical Practices and the US Food and Drug Administration. The duration of intervention was from April to May 2011. Main outcome Reduction in the incidence of HRAs use from the preintervention to postintervention study period. Findings The five most common abbreviations recorded prior to the interventions were ‘IJ for injection’ (28.6%), ‘SC for subcutaneous’ (17.4%), drug name and dose running together (9.7%), ‘OD for once daily’ (5.8%) and ‘D/C for discharge’ (4.3%). The incidence of the use of HRAs was highest in discharge prescriptions and dispensing records (72.7%) followed by prescriptions from in-patient wards (47.3%). After the intervention, the overall incidence of HRA was significantly reduced by 52% (ie, 53.6% vs 25.5%; p=0.001). In addition, there was a statistically significant reduction in the incidence of HRAs across all three settings: the pharmacy department (72.7% vs 39.3%), inpatient settings (47.3% vs 23.3%) and emergency wards (40.9% vs 10.7%). Conclusions Pharmacist-led educational interventions can significantly

    This study investigated the cross-cultural differences and similarity in health behaviors between Saudi and British adolescents. A school-based cross-sectional study was conducted at four cities in Saudi Arabia (Riyadh and Al-Khobar; N = 1,648) and Britain (Birmingham and Coventry; N = 1,158). The participants (14–18 year-olds) were randomly selected using a multistage stratified cluster sampling technique. Measurements included anthropometric, screen time, validated physical activity (PA) questionnaire and dietary habits. The overweight/obesity prevalence among Saudi adolescents (38.3%) was significantly (p < 0.001) higher than that found among British adolescents (24.1%). The British adolescents demonstrated higher total PA energy expenditure than Saudi adolescents (means ± SE = 3,804.8 ± 81.5 vs. 2,219.9 ± 65.5 METs-min/week). Inactivity prevalence was significantly (p < 0.001) higher among Saudi adolescents (64%) compared with that of British adolescents (25.5%). The proportions of adolescents exceeding 2 h of daily screen time were high (88.0% and 90.8% among Saudis and British, respectively). The majority of Saudi and British adolescents did not have daily intakes of breakfast, fruit, vegetables and milk. MANCOVA showed significant (p < 0.05) gender by country interactions in several lifestyle factors. There was a significant (p < 0.001) gender differences in the ratio of physical activity to sedentary behaviors. In conclusion, Saudi and British adolescents demonstrated some similarities and differences in their PA levels, sedentary behaviors and dietary habits. Unhealthy lifestyle behaviors among adolescents appear to be a cross-cultural phenomenon. PMID:24300072

    This study was conducted to explore Saudi high students' misconceptions in selected physics concepts. It also detected the effects of gender, grade level and location of school on Saudi high school students' misconceptions. In addition, a further analysis of students' misconceptions in each question was investigated and a correlation between students' responses, confidence in answers and sensibleness was conducted. There was an investigation of sources of students' answers in this study. Finally, this study included an analysis of students' selection of reasons only in the instrument. The instrument used to detect the students' misconceptions was a modified form of the Misconception Identification in Science Questionnaire (MISQ). This instrument was developed by Franklin (1992) to detected students' misconceptions in selected physics concepts. This test is a two-tier multiple choice test that examines four areas of physics: Force and motion, heat and temperature, light and color and electricity and magnetism. This study included a sample of 1080 Saudi high school students who were randomly selected from six Saudi educational districts. This study also included both genders, the three grade levels of Saudi high schools, six different educational districts, and a city and a town in each educational district. The sample was equally divided between genders, grade levels, and educational districts. The result of this study revealed that Saudi Arabian high school students hold numerous misconceptions about selected physics concepts. It also showed that tenth grade students were significantly different than the other grades. The result also showed that different misconceptions are held by the students for each concept in the MISQ. A positive correlation between students' responses, confidence in answers and sensibleness in many questions was shown. In addition, it showed that guessing was the most dominant source of misconceptions. The result revealed that gender and

    BACKGROUND Although virologically confirmed dengue fever has been recognized in Jeddah, Saudi Arabia, since 1994, causing yearly outbreaks, no proper seroepidemiologic studies on dengue virus have been conducted in this region. Such studies can define the extent of infection by this virus and estimate the proportion that may result in disease. The aim of this study was to measure the seroprevalence of past dengue virus infection in healthy Saudi nationals from different areas in the city of Jeddah and to investigate demographic and environmental factors that may increase exposure to infection. METHODS Sera were collected from 1984 Saudi subjects attending primary health care centers in six districts of Jeddah. These included general patients of various ages seeking routine vaccinations, antenatal care or treatment of different illnesses excluding fever or suspected dengue. A number of blood donors were also tested. Serum samples were tested by enzyme immunoassay (EIA) for IgG antibodies to dengue viruses 1, 2, 3, 4. A questionnaire was completed for each patient recording various anthropometric data and factors that may indicate possible risk of exposure to mosquito bites and dengue infection. Patients with missing data and those who reported a history of dengue fever were excluded from analysis, resulting in a sample of 1939 patients to be analyzed. RESULTS The overall prevalence of dengue virus infection as measured by anti-dengue IgG antibodies from asymptomatic residents in Jeddah was 47.8% (927/1939) and 37% (68/184) in blood donors. Infection mostly did not result in recognizable disease, as only 19 of 1956 subjects with complete information (0.1%) reported having dengue fever in the past. Anti dengue seropositivity increased with age and was higher in males than females and in residents of communal housing and multistory buildings than in villas. One of the six districts showed significant increase in exposure rate as compared to the others. Availability of

    High turnover rate among healthcare professionals is a very expensive price that healthcare organizations might pay if they don't have the proper strategies for motivating and satisfying their employees. Healthcare organizations should be able to identify areas that require more attention. Many studies discussed the vital link that bonds job satisfaction with motivation, which has a major impact on productivity, innovation, and overall organizational performance. Our study explored the level of job satisfaction and factors that motivate pharmacists in Saudi hospitals using mixed quantitative and qualitative methods. From pharmacy managers' point of view; financial rewards are more important than non-financial incentives and benefits. This contradicts with pharmacists' opinions; who ranked recognition, promotion, job satisfaction, job feedback, autonomy and task significance among the most influential motivators to pharmacists. These results show that managers need to revise their plans and provide further attention to ensure that effective motivation and retention strategies are put in place. PMID:27350504

    We attempted, through systematic review to explore the epidemiology and risk factors of Crohn's disease (CD) with special attention to the Kingdom of Saudi Arabia (KSA). We selected articles that contained population-based, epidemiological, and clinical character studies of CD. We collected data concerned with the prevalence, demographic features, and the possible etiology of CD that might explain its emergence in KSA. The prevalence of CD in Western countries ranged between 11-43/100,000 with flawless evidence of CD prevalence emerging in previously low incidence areas like Asia. Prevalence in KSA has markedly increased over the last 3 decades. Combined ileal and colonic involvement was the most frequently affected site. Diet, smoking, drugs, and westernization of life are assumed to contribute to the pathogenesis. There is convincing evidence of CD emerging in Asia, including KSA. Westernization of lifestyle and smoking is probably the major contributing factors. Genetic studies are warranted. PMID:24252887

    Unlike the venom of Echis carinatus from India, Pakistan, Nigeria, Kenya, Iran and Oman, Saudi Arabian E. carinatus venom is a poor activator of prothrombin. However, it possesses similar defibrinogenating activity to the other venoms. This is because the venom from Saudi Arabian snakes contains a calcium-dependent factor X activator. It is suggested that in future studies of the coagulant activity of venoms, the determination of plasma coagulant activity should be carried out in the presence of added calcium ions. This applies particularly to those venoms which do not act on plasma or fibrinogen, but which do cause in vivo defibrinogenation. PMID:3257079

    Background Few lifestyle factors have been simultaneously studied and reported for Saudi adolescents. Therefore, the purpose of the present study was to report on the prevalence of physical activity, sedentary behaviors and dietary habits among Saudi adolescents and to examine the interrelationships among these factors using representative samples drawn from three major cities in Saudi Arabia. Methods This school-based cross-sectional study was conducted during the years 2009-2010 in three cities: Al-Khobar, Jeddah and Riyadh. The participants were 2908 secondary-school males (1401) and females (1507) aged 14-19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, sedentary behaviors (TV viewing, playing video games and computer use), physical activity using a validated questionnaire and dietary habits. Results A very high proportion (84% for males and 91.2% for females) of Saudi adolescents spent more than 2 hours on screen time daily and almost half of the males and three-quarters of the females did not meet daily physical activity guidelines. The majority of adolescents did not have a daily intake of breakfast, fruit, vegetables and milk. Females were significantly (p < 0.05) more sedentary, much less physically active, especially with vigorous physical activity, and there were fewer days per week when they consumed breakfast, fruit, milk and diary products, sugar-sweetened drinks, fast foods and energy drinks than did males. However, the females' intake of French fries and potato chips, cakes and donuts, and candy and chocolate was significantly (p < 0.05) higher than the males'. Screen time was significantly (p < 0.05) correlated inversely with the intake of breakfast, vegetables and fruit. Physical activity had a significant (p < 0.05) positive relationship with fruit and vegetable intake but not with sedentary behaviors. Conclusions The high prevalence of sedentary behaviors, physical inactivity and

    A grain boundary (GB) in graphene is a linear defect between two specifically oriented graphene edges, whose title angles are denoted as θ1 and θ2, respectively. Here we present a systematic theoretical study on the structure and stability of GBs in graphene as a function of the misorientation angle, Φ = (θ1 - θ2) and the GB orientation in multi-crystalline graphene, which is denoted by Θ = (θ1 + θ2). It is surprising that although the number of disorders of the GB, i.e., the pentagon-heptagon pairs (5|7s), reaches the maximum at Φ ~ 30°, the GB formation energy versus the Φ curve reaches a local minimum. The subsequent M-shape of the Efvs. the Φ curve is due to the strong cancellation of the local strains around 5|7 pairs by the ``head-to-tail'' formation. This study successfully explains many previously observed experimental puzzles, such as the multimodal distribution of GBs and the abundance of GB misorientation angles of ~30°. Besides, this study also showed that the formation energy of GBs is less sensitive to Θ, although the twin boundaries are slightly more stable than others.A grain boundary (GB) in graphene is a linear defect between two specifically oriented graphene edges, whose title angles are denoted as θ1 and θ2, respectively.

    In herbaceous ecosystems worldwide, biodiversity has been negatively impacted by changed grazing regimes and nutrient enrichment. Altered disturbance regimes are thought to favour invasive species that have a high phenotypic plasticity, although most studies measure plasticity under controlled conditions in the greenhouse and then assume plasticity is an advantage in the field. Here, we compare trait plasticity between three co-occurring, C(4) perennial grass species, an invader Eragrostis curvula, and natives Eragrostis sororia and Aristida personata to grazing and fertilizer in a three-year field trial. We measured abundances and several leaf traits known to correlate with strategies used by plants to fix carbon and acquire resources, i.e. specific leaf area (SLA), leaf dry matter content (LDMC), leaf nutrient concentrations (N, C:N, P), assimilation rates (Amax) and photosynthetic nitrogen use efficiency (PNUE). In the control treatment (grazed only), trait values for SLA, leaf C:N ratios, Amax and PNUE differed significantly between the three grass species. When trait values were compared across treatments, E. curvula showed higher trait plasticity than the native grasses, and this correlated with an increase in abundance across all but the grazed/fertilized treatment. The native grasses showed little trait plasticity in response to the treatments. Aristida personata decreased significantly in the treatments where E. curvula increased, and E. sororia abundance increased possibly due to increased rainfall and not in response to treatments or invader abundance. Overall, we found that plasticity did not favour an increase in abundance of E. curvula under the grazed/fertilized treatment likely because leaf nutrient contents increased and subsequently its' palatability to consumers. E. curvula also displayed a higher resource use efficiency than the native grasses. These findings suggest resource conditions and disturbance regimes can be manipulated to disadvantage

    Global energy scenario is changing drastically toward decline, as new major discoveries of fossil fuel are not coming up significantly on regional basis. In case of Saudi Arabia, one of the largest fossil fuel producers, the major oil fields have started exhausting significantly as revealed from the literature research study. Considering the future energy crisis, different other renewable options presently have became imperative to be consider anticipating for the national development. Wind energy in one of them. The development of wind energy technology requires the baseline data relevant to the wind trends and their potentials. Under the present study, an attempt has been made to develop wind power density map of the Makkah Province of Saudi Arabia based on the meteorological data collected at different sparsely located weather stations. GIS application has provided a good option to interpolate the gap areas between the sparsely located weather recording stations. This paper describe the methodology and results of the present study.

    The Arabian Gulf is a shallow semi-closed water body. Several industrial complexes have been established along its coast line during the past decade. The effluent from these facilities is being discharged into the Gulf. These discharges pose potential hazards to the marine environment of the Arabian Gulf. The Saudi Arabian government is striving to protect the marine environment of the Gulf and has commissioned several studies to assess the damage from the industrial and municipal discharges. In these studies, marine organisms, for example, fish, clams, sea urchins, oysters, and plankton, along with sediments and seawater, have been analyzed for various pollutants. This study reports metal concentrations in pearl oysters collected from the Saudi Arabian coastal areas of the Arabian Gulf.

    Ambient air pollution in major cities of Saudi Arabia is a substantial environmental and health concern. A study was undertaken to assess the air quality of Jeddah, Saudi Arabia by the analysis of respirable particulate matter (PM2.5), black carbon (BC), trace metals (Na, Mg, Al, Si, S, Cl, K, Ca, Ti, V, Cr, Mn, Fe, Ni, Cu, Zn, Br, Sr, Cd, Sb, and Pb), and water-soluble ions (F-, Cl-, NO3-, SO42-, C2O42-, and NH42+). Sulfur and BC mass concentration ranged 0.99 - 7.39 μg/m3 and 0.70 - 3.09 μg/m3, respectively, while the PM2.5 mass concentration ranged 23 - 186 μg/m3. Maximum BC contribution to PM2.5 was 5.6%. Atmospheric PM2.5 concentrations were well above the 24 h WHO guideline of 20 μg/m3. Air Quality Index (AQI) indicates that there were 8% days of moderate air quality, 28% days of unhealthy air quality for sensitive groups, 55% days of unhealthy air quality, and 9% days of very unhealthy air quality during the study period. Sulfate SO42- dominated the identifiable components. The major contributors to PM2.5 were soil and crustal material; vehicle emissions (black carbon factor); and fuel oil combustion in industries (sulfur factor), according to the Positive Matrix Factorization (PMF). This study highlights the importance of focusing control strategies not only on reducing PM concentration, but also on the reduction of toxic components of the PM, to most effectively protect human health and the environment.

    Background Asthma, a common lung disease in children, is caused by excessive immune responses to environmental antigens. Objective Given the immuno-modulatory properties of vitamin D, the aim of the current study was to investigate the relationship between vitamin D levels and markers of asthma severity. Methods This was investigated in a 70 Saudi children with and without asthma and were recruited from the King Abdul Aziz University Hospital, Jeddah, Saudi Arabia, over the period of 11 months (May 2011-April 2012). Childhood asthma control test instrument was employed to assess the level of asthma control among asthmatic patients. Anthropometric measurements were taken and interviewer-administrated questionnaire was completed for all study participants. Pulmonary function test was performed by recording changes in the peak expiratory flow. Venous blood samples were withdrawn for measurements of vitamin D, bone profile, cytokines profile (interleukin-10, tumor necrosis factor-alpha, platelets derived growth factor), and atopy markers (IgE and eosinophil count). Results Hypovitaminosis D is highly prevalent among asthmatic children with highly significant increase in several markers of allergy and asthma severity as compared with healthy control children. Significant correlations between several inflammatory and immunological markers and vitamin D levels were also found. Finally, lower 25-hydroxyvitamin D levels were associated with a higher asthma prevalence in multivariable analysis. Conclusion Our study showed that hypovitaminosis D is highly prevalent in the whole population in addition to a highly significant increase in several markers of allergy and asthma severity among asthmatic children as compared with healthy control children.

    Background Data on the clinical presentation of rosacea among darker-skinned ethnic groups is scarce. This article presents the clinical spectrum of rosacea in Saudi female patients with differences highlighted according to skin types. Methods Female patients diagnosed with rosacea at the dermatology clinic in King Khalid University Hospital, King Saud University, Riyadh, Saudi Arabia, between February 2010 and May 2011 were studied prospectively. Data collected included demographics, duration of the disease, personal history of any atopic disorder, aggravating factors, cutaneous and ocular symptoms, the presence of migraine, Helicobacter pylori infection, skin phototypes, and the clinical types and severity of rosacea. Results Fifty patients consented to join the study: 20 (40%) were patients with skin type 4, 9 (18%) had skin type 5, and 21 (42%) had skin type 6. The cheeks, glabella, and chin were involved in 26 (52%) patients. Extrafacial lesions affecting chest, back, and ears were identified in 7 patients (14%). Severe erythematotelangiectatic rosacea was diagnosed in 21 patients (42%): skin type 4 comprised 50%, higher than the incidences for skin type 5 (22%) and skin type 6 (42.9%). The severe papulopustular subtype of rosacea was noted in 7 patients (14.0%), affecting 20% with skin type 4 and 14% with skin type 6. Severity of the erythematotelangiectatic or papulopustular subtypes of rosacea was not significantly associated with skin type (P=0.5691 and P=0.7740, respectively). Conclusion This study addresses the growing interest in skin diseases in dark-skinned individuals. Rosacea is one of the skin disorders that had always been described for fair-skinned populations, but our results indicate that darker-skinned individuals also can be affected by rosacea and the clinical presentation is similar to that seen in patients with fair skin.

    Objectives: To probe dental students’ perceptions on their cultural competency and international student exchange programs as a way of improving cultural competency training. Methods: A cross-sectional survey (n=460) was distributed to predoctoral students at the College of Dentistry, King Saud University, Riyadh, Kingdom of Saudi Arabia in May 2014 at the male and female university campuses. Descriptive statistics were carried out using Statistical Package for Social Sciences (p=0.05). Results: It was found that 79.6% of students think that teaching them regarding cultural diversity is important. Only 41% of students thought their dental education teaches them on the importance of volunteerism and philanthropy. Most students (89.8%) think that international student exchanges can enhance their cultural competence. Conclusion: In this study, it was found that students believe that cultural competence is important and participation in international student exchange programs can enhance their training.

    Over the last decade, science education researchers in the US have studied students' beliefs about science and learning science and measured how these beliefs change in response to classroom instruction in science. In this paper, we present an Arabic version of the Colorado Learning Attitudes about Science Survey (CLASS) which was developed to measure students' beliefs about physics at King Saud University (KSU) in Riyadh, Saudi Arabia. We describe the translation process, which included review by four experts in physics and science education and ten student interviews to ensure that the statements remained valid after translation. We have administered the Arabic CLASS to over 300 students in introductory physics courses at KSU's men's and women's campuses. We present a summary of students' beliefs about physics at KSU and compare these results to similar students in the US.

    We conducted a nationwide cross-sectional survey of 4872 mothers (mostly Saudi) to study infant feeding patterns. Information was collected about their feeding practices with their youngest child using pre-tested questionnaires. About four-fifths of the mothers had received health education about breastfeeding, most often from medical staff; younger mothers tended to be better informed. Approximately 92% fed colostrum to the newborn, but 76.1% had introduced bottle-feeding by 3 months (48.3% cited insufficient milk as the reason for introducing the bottle). This was significantly related to nationality and education level. Mixed feeding (breastfeeding and bottle-feeding) was popular. Solid foods tended to be introduced late and this was significantly related to nationality, age and education level. PMID:17037217

    Objective: We investigated the prevalence of psychiatric disorders among visitors to Faith Healers (FHs) in Riyadh, Saudi Arabia. We also studied the sociodemographic profiles for these visitors, in addition to their past psychiatric history, reason(s) for seeking FH help, and past and current treatment experience with FHs. Methods: We conducted a cross-sectional study among the visitors (n=321) to a number of faith healing settings in Riyadh, Saudi Arabia using a specially designed questionnaire and validated Arabic version of The Mini International Neuropsychiatric Interview. Results: Most of the participants were young adults (35.1±10.8 years) and males with intermediate and secondary levels of education who had not sought medical help prior to their visits. A high proportion of the FH visitors have diagnosable mental illnesses. Depressive and anxiety disorders were the most prevalent among the study participants; few visitors were affected by psychotic or bipolar disorders. Conclusions: The present study provides insight for understanding the type of patients with psychiatric disorders who visit Faith Healers.(FHs). The study highlights the tendency of psychiatric patients in Saudi Arabia to visit FHs, which could reflect the importance of further studies to clarify the impact of FHs on the management of those patients.

    2014-05-01

    The Najd Fault System of the Arabian-Nubian Shield is considered to be the largest Proterozoic Shear zone system on Earth. The shear zone was active during the late stages of the Pan African evolution and is known to be responsible for the exhumation of fragments of juvenile Proterozoic continental crust that form a series of basement domes across the shield areas of Egypt and Saudi Arabia. A three year research project funded by the Austrian Science Fund (FWF) and supported by the Saudi Geological Survey (SGS) has focused on structural mapping, petrology and geochronology of the shear zone system in order to constrain age and mechanisms of exhumation of the domes - with focus on the Saudi Arabian side of the Red Sea. We recognise important differences in comparison with the basement domes in the Eastern desert of Egypt. In particular, high grade metamorphic rocks are not exclusively confined to basement domes surrounded by shear zones, but also occur within shear zones themselves. Moreover, we recognise both exhumation in extensional and in transpressive regimes to be responsible for exhumation of high grade metamorphic rocks in different parts of the shield. We suggest that these apparent structural differences between different sub-regions of the shield largely reflect different timing of activity of various branches of the Najd Fault System. In order to tackle the ill-resolved timing of the Najd Fault System, zircon geochronology is performed on intrusive rocks with different cross cutting relationships to the shear zone. We are able to constrain an age between 580 Ma and 605 Ma for one of the major branches of the shear zone, namely the Ajjaj shear zone. In our contribution we present a strain map for the shield as well as early geochronological data for selected shear zone branches.

    During the last decade, Acinetobacter baumannii (AB) has been increasingly responsible for infections occurring in three particular contexts (in terms of patients and environment). Community AB pneumonia is severe infections, mainly described around the Indian Ocean, and which mainly concern patients with major co-morbidities. AB is also responsible for infections occurring among soldiers wounded in action during operations conducted in Iraq or Afghanistan. Lastly, this bacterium is responsible for infections occurring among casualties from natural disasters like earthquakes and tsunamis. Those infections are often due to multidrug-resistant strains, which can be implicated in nosocomial outbreaks when patients are hospitalized in a local casualty department or during their repatriation thereafter. The source of the contaminations which lead to AB infections following injuries (warfare or natural disasters) is still poorly known. Three hypotheses are usually considered: a contamination of wounds with environmental bacteria, a wound contamination from a previous cutaneous or oropharyngeal endogenous reservoir, or hospital acquisition. The implication of telluric or agricultural primary reservoirs in human AB infections is a common hypothesis which remains to be demonstrated by further specifically designed studies. PMID:21963271

    An interdisciplinary study based on long term data collected in the northern Adriatic relieved winter period to be crucial for the total annual zooplankton production in the region. Namely, yearly averages of some investigated zooplankton species in the 2000-2007 interval were highly related to their February and/or March abundances. The large winter zooplankton abundances appeared in winters of the "A type", in which freshened waters from the Po River spread over the region. Also, the production of phytoplankton was in winters of the "A type" higher than in winters of the "B type", in which these waters are restricted to the coastal areas and do not impact the open sea. That was presumably due to increase in nutrients. In fact, the total inorganic nitrogen and ortophosphate concentration in eastern part reached maximal February values in the 1990-2007 interval in winters of the "A type". Spreading of the Po River water across the northern Adriatic and appearance of the two winter types depends on the existing geostrophic circulation patterns and atmospheric and hydrologic conditions in the preceding months, thus enabling forecast. Obtained results are basis for the future theoretical ecological model which can explain long term changes in bioproduction in the region and be used in planning future environment actions aimed to sustained development, especially as winter phytoplankton and zooplankton production seems to reflect on annual catch of small pelagic fish important for Adriatic fishery, anchovy (Engraulis encrasicolus).

    Few studies have addressed racial differences in prostate cancer (PCa) detection between Western and Arabian countries, although PCa has a significantly lower prevalence in Arabic populations compared to Western populations. Therefore, an explanation of this difference is lacking. Serum prostate-specific antigen (PSA) is a valuable marker used to select patients who should undergo prostate biopsies, although the manner in which it is used may require adjustments based on the ethnic population in question. We investigated racial differences in the PCa detection rate between Canadian and Saudi populations. A retrospective analysis was performed of data collected prospectively over 5 consecutive years in urology clinics at the McGill University Health Center (MUHC) and King Saud University Hospital (KSUH). Men who had high (>4'ng/mL) or rising PSA levels and a negative digital rectal examination were eligible. A total of 1403 Canadian and 414 Saudi patients were evaluated for the study; 717 and 158 men, median age 64 and 68 years, were included in the MUHC and KSUH cohorts, respectively, P<0.0001). Median serum PSA, prostate volume, and PSA density values were 6.1'ng/mL, 47.3 g, and 0.12'ng·mL−1·g−1, respectively, for MUHC patients and 5.2'ng/mL, 64.5'g, and 0.08'ng·mL−1·g−1, respectively, for KSUH patients (P<0.0001, t-test followed by one-way ANOVA). In addition, the KSUH group had a significantly lower PCa detection rate among patients younger than 60 years of age and with PSA values <10'ng/mL. PMID:23802226

    This is the first time to clearly derive the comprehensive physical properties of aerosols at a rural background area in Saudi Arabia. Aerosol measurements station was established at a rural background area in the Western Saudi Arabia to study the aerosol properties. This study gives overview of the aerosol physical properties (PM10, PM2.5, black carbon and total number concentration) over the measurement period from November 2012 to February 2015. The average PM10 and PM2.5 concentrations were 95 ± 78 μg m-3 (mean ± STD, at ambient conditions) and 33 ± 68 μg m-3 (at ambient conditions), respectively. As expected PM10 concentration was dominated by coarse mode particles (PM10-PM2.5), most probably desert dust. Especially from February to June the coarse mode concentrations were high because of dust storm season. Aerosol mass concentrations had clear diurnal cycle. Lower values were observed around noon. This behavior is caused by wind direction and speed, during night time very calm easterly winds are dominating whereas during daytime the stronger westerly winds are dominating (sea breeze). During the day time the boundary layer is evolving, causing enhanced mixing and dilution leading to lower concentration. PM10 and PM2.5 concentrations were comparable to values measured at close by city of Jeddah. Black carbon concentration was about 2% and 6% of PM10 and PM2.5 mass, respectively. Total number concentration was dominated by frequent new particle formation and particle growth events. The typical diurnal cycle in particle total number concentration was clearly different from PM10 and PM2.5.

    Background: Smoking is the most important avoidable cause of premature morbidity and mortality in the world. The estimated annual death rate of 4.9 million people in 1999 is expected to rise to 10 million by the 2020s and 2030s, 7 million of which will occur in developing countries. Aim: The aim of the present study was to estimate the prevalence of smoking and assess its pattern among non-medical female college students in Dammam, Saudi Arabia. Materials and Methods: A cross-sectional study was conducted of 1020 female students selected from the literature and science colleges by multi-stage stratified random sampling technique with proportional allocation. Data were collected using a self-administered modified WHO Global Youth Tobacco Survey questionnaire. Results: Results revealed that occurrence of smoking among female college students was 8.6%. It was significantly higher among literature college students (12.1%) than among Science College students (3.4%). The mean age at which smoking started was 16 ± 2.4 years, with a minimum of 11 years. More than half of the students who smoked were cigarette smokers, while 43.2% were shisha smokers. There was a strong relationship between parents who smoked and daughters who smoked. The main motive for smoking was curiosity (44.3%), followed by relief of tension (26.1%). Conclusions: It may be concluded that smoking is increasing among female college students in Saudi Arabia. Accordingly, it is recommended that a preventive comprehensive health education program on smoking be initiated for females in middle schools, that stricter tobacco control measures be adopted by the government, and that anti-smoking clinics be established in colleges.

    Scorpion stings are a major public health problem in Saudi Arabia. The main victims are children who accidentally tread on a scorpion, about 900 children being admitted to hospitals each summer for such stings. Many cases are fatal. The pathophysiology of scorpion stings is complex and its management is difficult. Almost all body systems are affected but circulatory shock and pulmonary oedema are the usual cause of death. The treatment is based on scorpion antivenom and symptomatic treatment of the envenoming manifestations in an intensive care unit. The currently used antivenom is a polyvalent horse serum preparation given intravenously. PMID:7550843

    The Kingdom of Saudi Arabia has numerous large monogenetic volcanic fields, known locally as "harrats." The largest of these, Harrat Rahat (Figure 1), produced a basaltic fissure eruption in 1256 C.E. with lava flows traveling within 20 kilometers of the city Al-Madinah, which currently has a population of 1.5 million plus an additional 3 million pilgrims annually. With more than 950 visible vents and periodic seismic swarms, an understanding of the risk of future eruptions in this volcanic field is vital.

    Domestic water conservation in arid climates can result in efficient utilization of existing water supplies. The impacts of conservation measures such as the installation of water-saving devices, water metering and pricing schemes, water rationing and public awareness programs, strict plumbing codes, penalties for wasting water, programs designed to reduce leakage from public water lines and within the home, water-efficient landscaping, economic and ethical incentives are addressed in detail. Cost savings in arid climates, with particular reference to Saudi Arabia, in relation to some conservation techniques, are presented. Water conservation technology and tentative demonstration and implementation of water conservation programs are discussed.

    Growing evidence suggests that sleep is important for procedural learning, but few studies have investigated the effect of sleep on the temporal aspects of motor skill learning. We assessed the effect of a 90-min day-time nap on learning a motor timing task, using 2 adaptations of a serial interception sequence learning (SISL) task. Forty-two right-handed participants performed the task before and after a 90-min period of sleep or wake. Electroencephalography (EEG) was recorded throughout. The motor task consisted of a sequential spatial pattern and was performed according to 2 different timing conditions, that is, either following a sequential or a random temporal pattern. The increase in accuracy was compared between groups using a mixed linear regression model. Within the sleep group, performance improvement was modeled based on sleep characteristics, including spindle- and slow-wave density. The sleep group, but not the wake group, showed improvement in the random temporal, but especially and significantly more strongly in the sequential temporal condition. None of the sleep characteristics predicted improvement on either general of the timing conditions. In conclusion, a daytime nap improves performance on a timing task. We show that performance on the task with a sequential timing sequence benefits more from sleep than motor timing. More important, the temporal sequence did not benefit initial learning, because differences arose only after an offline period and specifically when this period contained sleep. Sleep appears to aid in the extraction of regularities for optimal subsequent performance. (PsycINFO Database Record PMID:27214501

    Psychosocial characteristics including depression, attitude towards their handicap, hobbies and problems of living situations have been studied among 152 male students in the Institute for the Blind (n = 44) and in the Institute for the Deaf (n = 108) in Abha City. All students were subjected to a constructed Arabic version of the rating scale 'Children Depression Inventory (CDI)'. They were categorised according to their scores on this CDI, into depressed and non-depressed. Also, an interview questionnaire was administered to collect data related to the handicap, such as age of onset, and its cause and family history of the same handicap. The effect of the handicap upon the attitudes of students in relation to their social tendencies, hobbies and problems in living situations was studied. The mean ages for blind and deaf students were 15.70 and 13.04 years respectively. About 91.% and 75.% of blind and deaf students respectively were born with their handicap. Depression was more prevalent among the blind (14%) than among the deaf (6.5%) students. Difficulty in mobility was the main problem among blind students (44%) while difficulty in communication with people was the main problem among the deaf (52%). Reading was the commonest hobby for the blind (51%), while playing football was the commonest among the deaf (62%). This information should be considered when planning for rehabilitative services for these groups. PMID:8356208

    This study was conducted to explore Saudi middle and high school science teachers' conceptions of the Nature of Science (NOS). It also detected the effects of gender, science content major, and years of teaching experience on teachers' conceptions of the NOS. The study included a sample of 786 science teachers (137 male and 649 female) who were teaching in middle and high schools in Riyadh, Saudi Arabia in the 1995-1996 academic year. The study was conducted using a translated version of the Nature of Science Scale (NOSS) developed by Kimball (1967). The scale contains 29 items ranging from "agree" to "disagree", and the scoring of the items ranged from 29 to 87. The lowest score is 29 (1 x 29) and the highest score possible on the test is 87 (3 x 29 items). The data collected was statistically analyzed using descriptive statistics and Analysis of Variance (ANOVA). The study revealed that Saudi science teachers as a group hold numerous misconceptions about the NOS with a significant difference in understanding the NOS between the male and female teachers. The study also showed that teachers with a major in physics held more adequate views than did teachers with other majors. In addition, novice teachers were found to have more adequate conceptions of the NOS than did experienced teachers.

    The prevalence's of overweight and obesity have grown to epidemic proportions in Saudi Arabia the past few years, epidemiological studies have suggested that sleeping for less than seven hours/day is associated with increased morbidity in terms of the development of obesity. The aim of this study was to examine the association between sleep quality and different measures of obesity (body mass index, waist circumference and body fat percentage) and some lifestyle habits among female university students. A cross-sectional study targeted a convenience sample of 233 undergraduate female students at King Faisal University (KFU) in AL-Hasa, Saudi Arabia. The results indicated that poor sleep quality was common in students (54%) with mean total sleeping hours of five hours/day. Poor sleep quality was associated with overweight/obese (OR 4.210, P=0.000), at risk waist circumference (OR 2.005, P=0.009), moderate/high body fat percentage (OR 1.058, P=0.025), low physical active (OR 2.045, P=0.037), and skipping breakfast (OR 2.710, P=0.003). In conclusion, the present study highlights the prevalence of poor sleep quality among female university students in Saudi Arabia, and they support previously published studies indicating that poor sleep quality was associ-ated with different measures of obesity and some of lifestyle habits. Sleep quality is an untraditional approach that might be used to prevent or treat overweight and obesity. PMID:27530573

    This is a retrospective study in which we report our clinical experience during the period from January 1990 to December 2009, from a paediatric endocrine clinic at King Khalid University Hospital (KKUH), Riyadh, Saudi Arabia. The diagnosis of rickets and oestomalacia was based on clinical, biochemical and radiological data. Eighty-one (34 males and 47 females) children and adolescents with rickets or osteomalacia aged 2 to 18 years (mean; 9.5 years) were evaluated. The commonest causes were nutritional; either low Vitamin D or calcium, or both. In 58 (71.60%) patients, eight patients (9.87%) were due to chronic use of anticonvulsant medications, while five (6.17%) patients were diagnosed to have celiac disease. Non-specific symptoms, such as bone pain and fatigue were the most common presenting symptoms which may indicate that other cases were possibly missed. Lack of direct sun exposure and malnutritional practices were evident. Several genetically inherited disorders were diagnosed; including; hypophosphataemic rickets in three (3.70%), vitamin D-dependent-rickets type 2 in five (6.17%) and pseudohypo-hyperparathyroidism in one (1.23%) child. Rickets was secondary to chronic renal failure in only one patient (1.23%). In conclusion, a diversity of disorders caused rickets or osteomalacia in our series. Paediatricians should be familiar with such different types and able to differentiate them from disorders mimicking rickets. rickets, such as hypophosphatasia, and metaphyseal dysplasias. An active plan should be put in place to prevent rickets and osteomalacia among young age groups.

    Ultrastructural characteristics of merogony and the development of mature merozoits and macrogametogensis of Eimeria sp. infecting the Libyan jird were investigated. Mono and binucleated schizonts were detected. Developed merozoites showed all the apicomplexan architecture (Pellicle, conoid, rhoptries, micronemes ... etc). Transformation into macrogametes were studied. Early macrogamonts characterized by the loss of all apicomblexan characters and the appearance of wall-forming bodies were the first indication for macrogametogenesis. As development precepded, two types of wall forming bodies (I, II) were clearly detected. Cell organelles including amylopectin granules and lipid globules were greatly increased in mature macrogametes. Young oocyst (zygote) with double-layer oocyst wall were also detected. Host cell reaction due to infection included hypertrophy of the infected host cell, enlargement, deformation and displacement of the host cell nucleus. Swollen and degeneration of mitochondria, endoplasmic reticulum and cytoplasmic vacuolation of the host cell. All parasite stages were enclosed in parasitophorous vacuole limited by unit membrane. Extended damage effect appeared in some neighboring host cell indicating the secretion of some toxins by the parasite. PMID:26485841

    Ramsay, Colin R.; Odell, John; Drysdall, Alan R.

    A universal classification scheme for felsic plutonic rocks of the Arabian Shield remains an important and elusive objective. The extensive data available for felsic plutonic rocks of the Midyan region, which have been assigned to intrusive suites of the alkali granite, alkali-feldspar granite, monzogranite, granodiorite and trondhjemite associations, provide material for a pilot study. Discriminant analysis of compositional data has yielded multivariate classification functions which successfully assign samples to their proper suites. Functions which use major-oxide values have a better success rate than those based on trace elements, but both are particularly effective in distinguishing samples of the two suites with important mineralizing potential. Test classification of data from another part of the Arabian Shield suggests that the technique and the classification functions are effective beyond the Midyan region. Multivariate discriminant analysis can therefore be used as an aid to mapping, correlating and/or assessing the mineral potential of felsic plutons, and may form the basis for an objective, sensitive and concise classification scheme for Arabian felsic plutonic rocks.

    In a world of generalized floating exchange rates, it is not enough to solve the problem of exchange rate policy by determining whether to peg or float the currency under consideration. It is also necessary to choose to what major currency to peg. The main purpose of this study is to investigate and determine empirically the optimum currency peg for the Saudi riyal. To accomplish this goal, a simple conventional trade model, that includes variables found in many other studies of import and export demand, was used. In addition, an exchange rate term was added as a separate independent variable in the import and export demand equations in order to assess the effect of exchange rate on the trade flows. The criteria for the optimal currency peg in this study were based on two factors. First, the error statistics for projected imports and exports using alternative exchange rate regimes. Second, variances of projected imports, exports and trade balance using alternative exchange rate regimes. The exchange rate has a significant impact on the Saudia Arabian trade flows which implies that changes in the riyals value affect the Saudi trade deficit. Moreover, the exchange rate has a more powerful effect on its aggregate imports than on the world demand for its exports. There is also a strong support for the hypothesis that the exchange rate affects the value of the Saudi bilateral trade with its five major trade partners. On the aggregate level, the SDR peg seems to be the best currency peg for the Saudi riyal since it provides the best prediction errors and the lowest variance for the trade balance. Finally, on the disaggregate level, the US dollar provides the best performance and yields the best results among all the six currency pegs considered in this study.

    This study was designed to investigate the relationships between science misconceptions and working memory capacity in Saudi adolescent students. The participants in this study were from eleventh and twelfth grades; both male and female students and natural and social science Saudi comprised the sample. Also investigated in this study were the conceptions and misconceptions of gravity in a non-European culture, that is Saudi culture, and the variables that differentiated those individuals who could overcome their misconceptions from those who could not and the gender differences in science misconceptions in the context of Saudi culture. Another important focus of this study was to investigate the participants' responses and explanations on the science misconceptions tasks (WLT and EGT). As would be expected, there was a strong correlation between WLT and EGT in the responses of students and their explanations. The most successful students on the WLT and EGT were natural science students rather than social science students, and there were no gender differences between male and female participants. Also investigated were the correlations between the dependent variables (i.e., the WLT and EGT; the measures of science misconceptions) and the independent variables, which were the visual working memory capacity tasks (i.e., FIT and VPS), the field independence/dependence (FASP), students' grade point average (GPA), age, academic major, gender, and grade level. It was found that both of the dependent variables (i.e., the WLT and EGT) correlated significantly with the same independent variables, the FIT, VPS, FASP, academic major, and students' grade point average (GPA).

    Demand for basic petrochemicals, such as propylene, butenes, and aromatics, is increasing in Saudi Arabia. This paper discusses how increased demand for these materials will require a change to heavier feedstocks, such as butanes, naphtha, and gas oil, for the next generation of Saudi Arabian ethylene plants. Changing to heavier ethylene plant feedstocks would also take pressure off of limited ethane supplies in the region. Ethylene production in Saudi Arabia currently has the advantages of low-cost feedstock, cheap energy, and low-cost capital loans. The existing ethylene plants are designed to crack ethane and produce, primarily, ethylene.

    The objective of this study is to explore the knowledge, attitudes and intake of energy drinks among adolescents in Saudi Arabia. A multi-stage stratified sampling procedure was carried out to select 1061 school children aged 12–19 years, from Jeddah city, Saudi Arabia. A short self-reported questionnaire was administrated in order to collect the data. Of adolescents in the study, 45% drank energy drinks (71.3% males and 35.9% females; P<0.001). Advertisements were the main source of information on energy drinks (43%). The major reasons for consuming energy drinks were taste and flavour (58%), to ‘try them’ (51.9%) and ‘to get energy’ (43%), albeit with significant differences between genders (P<0.001). About half of the adolescents did not know the ingredients of these drinks, and 49% did not know that they contain caffeine (P-values <0.006 and <0.001 between genders, respectively). The greater majority (67%) considered energy drinks to be soft drinks. The study indicates the need for Saudi adolescents to be warned on the over-consumption of energy drinks. The study brings to attention the need for educational programmes related to increasing awareness in the community of the health effects related to high consumption of energy drinks. PMID:24576364

    Objectives: To determine the distribution of various molecular subtypes of breast cancer in Saudi Arabia and to assess the association between these subtypes and age at diagnosis, tumor size, histopathological type, grade, presence of carcinoma in-situ, and lymph node status. Methods: This observational retrospective study, between January 2010 and December 2014, was conducted at King Khalid University Hospital, Riyadh, Saudi Arabia. We classified 359 breast cancers into 4 molecular subtypes, using immunohistochemistry: luminal A (estrogen receptor [ER], or progesterone receptor [PR] positive and human epidermal growth factor receptor 2 [HER2] negative), luminal B (ER and/or PR positive and HER2 positive), HER2-positive (ER and PR negative and HER2 positive), and triple negative (ER, PR, and HER2 negative). We evaluated the relationship between these subtypes and clinicopathological features using Chi square test. Results: The most prevalent subtype was luminal A (58.5%), followed in descending order of frequency by triple negative (14.8%), luminal B (14.5%), and HER2-positive (12.3%). The average age at diagnosis was 49.8 years, and average tumor size at diagnosis was 3.19 cm. Conclusion: Luminal A tumor was the most common molecular subtype and HER2-positive was the least common. Most lobular carcinomas were luminal A tumors. Human epidermal growth factor receptor 2-positive and triple negative tumors had a higher histologic grade and a larger tumor size at diagnosis, and they were more common in women under 50 years. Carcinoma-in-situ was least common in triple negative tumors. We found no association between lymph node status and molecular subtypes. PMID:27146612

    Objectives Epidemiological and molecular studies have shown that sleep duration is associated with metabolic syndrome (MtS), a disease that is on the rise in the Kingdom of Saudi Arabia. We aim to investigate the association between sleep duration and selected cardiometabolic risk factors of MtS in a Saudi Arabian population. Setting Secondary care was given to the participants. There were 2 participating centres, shopping malls in North and South Jeddah, Saudi Arabia. Participants We recruited 2686 participants over a 1-year study period. Participants were selected based on their willingness. The only criterion for exclusion was living in the area (North or South Jeddah) for less than 15 years. Planned and primary outcome measures Participants were measured for blood sugar levels, blood pressure and body mass index. All participants were asked to fill out a questionnaire. Results There was a positive association between longer sleep duration and obesity, hypertension and hyperglycaemia. The adjusted ORs for obesity, hypertension and hyperglycaemia were 1.54 (95% CI 1.20 to 1.98), 1.89 (95% CI 1.45 to 2.48) and 1.59 (95% CI 1.19 to 2.13), respectively, in participants sleeping >8 h/night, as compared with those sleeping 7 h. The positive associations between longer sleep duration, defined as sleeping >7 h, and the disease status, did not differ from other risk factors such as physical activity and nutrition. Conclusions This is the first epidemiological study reporting on the association between sleep duration and cardiometabolic risk factors of MtS in a Saudi Arabian population. Sleep durations of 8 h or greater were found to be associated with all 3 cardiometabolic risk factors: obesity, hypertension and hyperglycaemia, and this relationship was not confounded by quality of nutrition or physical activity levels.

  7. Nd, Pb, Sr, and O isotopic characterization of Saudi Arabian Shield terranes

    2006-01-01

    New Nd, Sr and O isotopic data for granitoid rocks of the Saudi Arabian Shield are presented together with published Nd, Pb, Sr and O isotopic data and all available geologic and geochronologic information to re-evaluate the terranes defined for the Saudi Arabian part of the Arabian-Nubian Shield. Three groups of terranes are identified: 1) the western arc terranes, 2) the eastern arc terranes, and 3) the Khida terrane. The Khida terrane is the only terrane composed of pre-Neoproterozoic continental crust. The western arc terranes are of oceanic arc affinity, and have the least radiogenic Pb and Sr and most radiogenic Nd isotopic compositions and some of the lowest ??18O values of any rocks of the Saudi Arabian Shield. Although some previous studies have characterized the eastern arc terranes as of continental affinity, this study shows that they too are composed of Neoproterozoic oceanic arcs, although their sources have slightly elevated 208Pb/204Pb, Nd, Sri, and ??18O values compared to the western arc terranes. These data suggest that either the isotopic composition of the mantle source for the western arc terranes is more depleted than that of the eastern arc terranes or the eastern arc terranes have been mixed with a small amount of cratonic source material, or both. We further elaborate on the Hulayfah-Ad Dafinah fault zone as a major boundary within the Saudi Arabian portion of the East African Orogen. With further study, its northern extension may be shown to pass through what has been defined as the Hail terrane, and its southern extension appears to lie under cover east of the Tathlith-Malahah terrane and extend into Yemen. It may represent the collision zone between East and West Gondwana, and at the very least it is an important suture between groups of arc terranes of contrasting isotopic composition caught between two converging continents.

    The gastropod fauna of the Upper Cretaceous Aruma Formation in central Saudi Arabia comprises fifteen species belonging to fifteen genera, fourteen families, and five clades. The species are not abundant at any individual stratigraphic level but are equally and irregularly scattered in the formation. The studied species come mainly from the Hajajah Member of Upper Cretaceous Aruma Formation in central Saudi Arabia. Calliomphalus orientalis (Douvillé, 1916); Coelobolma corbarica Cossmann, 1918; Turritella (Torquesia) figarii Quaas, 1902; Neoptyxis olisiponensis (Sharpe, 1850) and Otostoma (Otostoma) divaricatum (d'Orbigny, 1847) are recorded from the Upper Cretaceous of central Arabia for the first time. The identified species have a close affinity to the Tethyan fauna known from other parts in Asia, Africa and Europe. Herbivores and predators are the dominant trophic groups which may indicate shallow marine lagoonal and relatively open marine environment.

    Approximately 60 % of the 2,150,000 km2 area of Saudi Arabia is underlain by soluble sediments (carbonate and evaporite rock formations, salt diapirs, sabkha deposits). Despite its hyper-arid climate, a wide variety of recent sinkholes have been reported in numerous areas, involving significant property losses. Human activities, most notably groundwater extraction, have induced unstable conditions on pre-existing cavities. This work provides an overview of the sinkhole hazard in Saudi Arabia, a scarcely explored topic. It identifies the main karst formations and the distribution of the most problematic sinkhole areas, illustrated through several case studies covering the wide spectrum of subsidence mechanisms. Some of the main investigation methods are presented through selected examples, including remote sensing, trenching and geophysics. Based on the available data, the main causal factors are identified and further actions that should be undertaken to better assess and manage the risk are discussed.

    In Saudi Arabia, the major outdoor anthropogenic source of carbon monoxide (CO) is the 4,280,986 cars registered in the Kingdom last year. Of these vehicles, approximately 1,300,000 are registered in the Riyadh area. The major sources of indoor CO in Riyadh are gas cooking facilities, kerosene heaters, charcoal burners, hubble bubble pipes (water pipes), and tobacco smoking. The current Saudi Arabian Ambient Air Quality Standards (SAAQS) for CO are 10 mg/m{sup 3} (9 ppm) maximum for 8-hour average exposure, and 40 mg/m{sup 3} (35 ppm) for 1-hour average exposure. The allowable exceedance is twice per month. These standards are the same for the United States except no exceedance is allowed. The objective of this study was to evaluate the CO levels indoors and outdoors at four sites in Riyadh. Continuous sampling was conducted at four sites with Ecolyzer Series 200 Monitors, together with Rustrak Recorders Model 288.

    Introduction This survey evaluates knowledge, attitudes and practices of medical students towards use of antibiotics for upper respiratory infections (URTIs). Methodology Cross-sectional questionnaire study among 1042 randomly selected medical students in Saudi Arabia. Results Respondents were mostly Saudis (97.5%), had previous knowledge of antibiotics (99.7%) and their usage (98.3%) against bacterial infections (93.7%). 18.1% thought that they could be used for viral infections. Nearly all students (97.2%) used antibiotics themselves during the previous year and self-medication without a prescription was high at 49% of cases. Most antibiotics were taken for URTI symptoms (61.8%). Female medical students had better knowledge on antibiotic effectiveness against bacteria and viruses, and overall knowledge increased with study year. Health seeking behaviour rates for symptoms of RTI and associated estimated necessity for antibiotics varied but were highest for cough with yellow/green phlegm. Conclusions The depth of knowledge that healthcare professionals have in relation to the proper use of antibiotics is essential in spreading the right message within communities. This is the first large study among medical students in Saudi Arabia, shedding important light on areas for improvement in the medical curriculum as well as antibiotic practices of medical students themselves.

    Objectives: To study factors that influence the desire to utilize breast reconstruction after mastectomy, and to investigate the barriers to reconstruction among women in Saudi Arabia. Methods: We conducted a cross-sectional study at 2 surgical centers in Jeddah, Saudi Arabia. A self-administered questionnaire was distributed to all breast cancer patients attending the surgery clinics for follow-up after mastectomy between January and March 2013. Ninety-one patients met the study inclusion criteria. The first part of the questionnaire covered the demographic and socioeconomic information regarding factors that might influence the desire to utilize breast reconstruction including possible barriers. Multivariate logistic regression was used to determine the significant predictors of the desire to undergo reconstruction. Results: Overall, 16.5% of patients underwent breast reconstruction after mastectomy. Young age and high educational attainment were significantly associated with an increased desire to undergo reconstruction. The main barriers to reconstruction were the lack of adequate information on the procedure (63%), concerns on the complications of the procedure (68%), and concerns on the reconstruction interfering with the detection of recurrence (54%). Conclusion: Age and educational level were significant predictors of the desire to utilize breast reconstruction. Furthermore, modifiable barriers included the lack of knowledge and misconceptions on the procedure. Addressing these issues may increase the rate of breast reconstruction in Saudi Arabia.

    Objectives: To evaluate infection control and the incidence of bacterial pathogens in Emergency Medical Service (EMS) ambulances in Riyadh, Saudi Arabia. The effectiveness of fumigation techniques used for these ambulances to minimize the spread of infection to transported patients and pre-hospital care providers was also assessed. Methods: Based on previous literature review indicating a higher propensity of microbial load, 3 areas within the ambulance, such as, stretcher handle, oxygen flow meter knob, and interior handle of the rear door were selected for specimen collection. Swab samples were collected both in the day and night shift, after the intended disinfection and cleaning (before and after fumigation). Micro-organisms were identified using standard procedures. This phase-I study was conducted at the Emergency Medical Services Department, Prince Sultan Bin Abdulaziz College of Emergency Medical Services, Al Malaz, King Saud University, Riyadh, Saudi Arabia between October and November 2013, wherein a total of 10 ambulances from the Saudi Red Crescent Authority in Riyadh were selected for inclusion in the study. Results: The specimens from all 10 ambulances showed similar results. In post disinfection and before fumigation, swab samples showed positive cultures that grew moderate to large quantities of environmental and skin flora. However, almost all organisms were susceptible to the fumigation technique. Conclusion: This study confirms the importance of evaluating the frequency and efficiency of various fumigation techniques as an ambulance is a potential reservoir for microbial transmission to patients and staff.

    Carbapenem-resistant Acinetobacter baumannii (CR-AB) represents a major health-care problem, causing high rates of morbidity and mortality. This study investigated the clonality of CR-AB isolated from diabetic patients from different regions in Saudi Arabia, as well as the relatedness of the β-lactamase genes. A total of 64 non-repetitive CR-AB clinical isolates were collected from 16 different regions in Saudi Arabia from intensive care patients. Isolates were identified phenotypically by the Vitek 2 compact system and genotypically by amplification of the blaOXA-51-like gene. The target sequences were amplified by PCR and the clonal diversity of the isolates was explored by PFGE. Resistance studies revealed that the prevalence of imipenem and meropenem resistance was 92% and 96%, respectively, while the vast majority of the isolates were susceptible to tigecycline and colistin. In addition, blaVIM and blaOXA-23 were the most prevalent genes in the isolates under investigation, while ISAba1 was the most dominant insertion sequence. PFGE results showed 13 clusters; clone H was dominant, comprising 20 isolates from four hospitals, followed by clones C and F, comprising 11 isolates each from three and six hospitals, respectively. Moreover, the current study signified the clonal diversity of CR-AB in Saudi Arabia and showed the ability of some clones to infect patients in many different cities. PMID:25106863

    The objective of this study was to evaluate the factors predictive of clinical pregnancy in the first superovulation/intrauterine insemination (SO/IUI) cycle of couples with favourable female characteristics. We analyzed retrospectively the first SO/IUI cycle of 306 infertile couples with mild male factor infertility and unexplained infertility. The women had a favourable prognosis in terms of ovarian reserve. Univariate logistic regression analyses identified body mass index (BMI) [odds ratio (OR) = 0.9, P = 0.014], sperm concentration [OR = 1.007, P = 0.007] and inseminating motile sperm count (IMC) [OR = 1.007, P = 0.032] as significant predictive factors of clinical pregnancy. Multivariate logistic regression analysis identified BMI [OR = 0.87, P = 0.008] and sperm concentration [OR = 1.008, P = 0.011] as significant factors. Pregnant and non-pregnant groups did not differ significantly in terms of the age and smoking status of the woman, duration and type of infertility, length of the stimulation, total gonadotropin dosage or antral follicle count. Of the female characteristics investigated, BMI was the most significant predictive factor of clinical pregnancy in the first SO/IUI cycle of couples with unexplained or mild male factor infertility and favourable female characteristics. In overweight women, weight loss should be advised before starting SO/IUI. Sperm concentration and IMC were significant male predictive factors for clinical pregnancy in the first SO/IUI.

    Aim To assess the knowledge, attitudes, and perceptions of Saudis towards participating in clinical trials (CTs). Methods A cross-sectional study was conducted on 232 Saudi adult patients and their companions visiting adult outpatient clinics at King Fahad Medical City, Riyadh, Saudi Arabia. Data were collected using a self-administered questionnaire based on information obtained from the literature. The questionnaire was divided into four sections, one covering the respondents’ demographics, and the other three assessing knowledge, attitudes, and perceptions towards participating in CTs. Results A total of 148 (63.8%) respondents were males, and 52 (22.4%) participants had been invited to participate in a CT previously. Of those, 39 (75%) participated. Knowledge about the essential elements of informed consent ranged from 55.7% (number of participants needed) to 85.7% (confidentiality of personal information). The majority (163, 73.8%) of respondents was willing to participate in a CT after consulting their family physician and 130 (58.0%) respondents would be motivated to participate in a CT if they were healthy. Only 36.8% of the respondents believed that patients who participated in a CT received the best care. Moreover, 110 (48.7%) respondents believed that research was conducted in a responsible and ethical manner. Conclusions The present study assessed the current understanding of CTs among Saudi participants. Although the majority of participants had an acceptable level of knowledge about CTs, they exhibited conditional attitudes and misperceptions towards participating in a CT. Increased patient awareness may improve patients’ attitudes towards ethical conduct of CTs. PMID:26848750

Methods: A retrospective study was carried out of 476 preterm infants who were admitted with the diagnosis of prematurity to King Fahd Hospital of the University, Al-Khobar, Saudi Arabia, between June 2008 and 2013. Demographics, birth weight, and neonatal survival rate were analyzed. Results: Four hundred and seventy-six preterm infants were admitted with a total prevalence of 7.5%. Descriptive analysis revealed 55% were males. Extremely preterm infants (<28 weeks’ gestation) comprised 9% and very preterm infants (28 to <32 weeks’ gestation) comprised 20%. Extremely low-birth-weight (ELBW) infants (<1000 g) comprised 11%. One hundred and fifty-seven (32%) infants were small for gestational age. Out of the total number of ELBW infants, 58% of them were discharged. The overall mortality was 7.6%. The mortality rate of male infants was 53%. The survival to discharge according to gestational age ranged from 30-97.6%. Conclusion: The estimated prevalence of preterm births in a university hospital in eastern province of Saudi Arabia, is consistent with various studies from different parts of the world.

    Objectives: To determine the degree of satisfaction and acceptance of stroke patients, their relatives, and healthcare providers toward using telestroke technology in Saudi Arabia. Methods: A cross-sectional study was conducted between October and December 2012 at King Abdulaziz Medical City, Ministry of National Guard Affairs, Riyadh, Saudi Arabia. The Remote Presence Robot (RPR), the RP-7i® (FDA- cleared) provided by InTouch Health was used in the study. Patients and their relatives were informed that the physician would appear through a screen on top of a robotic device, as part of their clinical care. Stroke patients admitted through the emergency department, and their relatives, as well as healthcare providers completed a self-administered satisfaction questionnaire following the telestroke consultation sessions. Results: Fifty participants completed the questionnaire. Most subjects agreed that the remote consultant interview was useful and that the audiovisual component of the intervention was of high quality; 98% agreed that they did not feel shy or embarrassed during the remote interview, were able to understand the instruction of the consultant, and recommended its use in stroke management. Furthermore, 92% agreed or strongly agreed that the use of this technology can efficiently replace the physical presence of a neurologist. Conclusion: Results suggest that the use of telestroke medicine is culturally acceptable among stroke patients and their families in Saudi Arabia and favorably received by healthcare providers.

    Objectives: To assess completeness of reports in the Saudi Adverse Event Reporting System (SAERS), which is a part of the Saudi Food and Drug Authority pharmacovigilance system for monitoring the safety of medications. Methods: A cross-sectional study was conducted in Riyadh, Saudi Arabia using the reports that were received between December 2009 and June 2012 in the SAERS. The completeness was assessed by reviewing the components of the adverse drug reactions (ADRs) form, and how many fields were completed. Descriptive statistics are reported. Result: There were 14,783 reports during the study period. Eighty percent of these reports were spontaneous reports. Information related to the drug (99%) and adverse events (98%) of the reports were completed. While the patient’s demographic data were completed only in 38% of all reports, the least completed item in the ADRs form was the reporter information (15%). The most reported drug class was tumor necrosis factor inhibitors (7%), whereas events involving the respiratory organ system were the most frequently reported (4.5%). Conclusion: Although the SAERS is considered new, it has a high number of reports. More efforts are needed to improve the completeness of the SAERS to be a good source to assess the signals between events and suspected drugs, especially when there is a high number of reports.

    Background and Objectives: Although the prevalence of childhood obesity has increased significantly in Saudi Arabia, parents are unable to appreciate obesity in their child. The objective of the study was to identify the percentage of parents who misclassify the status of child's weight, and determine whether there is a difference between those parents whose children are overweight and obese and those with children of normal weight. Materials and Methods: This cross-sectional study included 601 children aged 6-10 years. The children were recruited from the primary schools located in Al-Qassim, Saudi Arabia. The body mass index of the children was assessed in the school, and their parents responded to a self-administered questionnaire which contained questions on parental perception of the children's weight/obesity status. Data were entered and analyzed using SPSS. Results: Parents with overweight/obese children had significantly more misclassification than those with normal weight children. Ninety percent of parents of the 81 overweight children misclassified and reported that their child had normal weight, while 65% of parents of the 61 obese children, misclassified the child's weight status. Conclusions: The level of misclassification of children's weight status by parents is high. Saudi parents with overweight and obese children do not recognize their child's weight status. Parents’ awareness of childhood obesity and its negative health impact needs to be improved. PMID:27625586

    Doxorubicin (DOX) is an anthracycline antibiotic widely used as a chemotherapeutic agent in the treatment of several tumours. However, its cardiac toxicity limits its use at maximum therapeutic doses. Most studies implicated increased oxidative stress as the major determinant of DOX cardiotoxicity. The local Saudi flora is very rich in a variety of plants of quite known folkloric or traditional medicinal uses. Tribulus macropterus Boiss., Olea europaea L. subsp. africana (Mill.) P. S. Green, Tamarix aphylla (L.) H. Karst., Cynomorium coccineum L., Cordia myxa L., Calligonum comosum L' Hér, and Withania somnifera (L.) Dunal are Saudi plants known to have antioxidant activities. The aim of the current study was to explore the potential protective effects of methanolic extracts of these seven Saudi plants against DOX-induced cardiotoxicity in rats. Two plants showed promising cardioprotective potential in the order Calligonum comosum > Cordia myxa. The two plant extracts showed potent in vitro radical scavenging and antioxidant properties. They significantly protected against DOX-induced alterations in cardiac oxidative stress markers (GSH and MDA) and cardiac serum markers (CK-MB and LDH activities). Additionally, histopathological examination indicated a protection against DOX-induced cardiotoxicity. In conclusion, C. comosum and C. myxa exerted protective activity against DOX-induced cardiotoxicity, which is, at least partly, due to their antioxidant effect. PMID:22888535

    The aim of this study was to investigate the attitudes and use of complementary and alternative medicine (CAM) among Saudi Arabian adolescents. A multistage stratified sampling method was used to select 736 adolescents (358 males, 378 females) aged 15-19 years from secondary schools. The study was carried out in Al-Khobar city, Eastern region of Saudi Arabia. The findings revealed that the use of CAM by adolescents in their lifetime ranged from 1.6% for acupuncture to 58.6% for honey treatment, with significant differences between genders, except in the use of dietary supplements, black cumin, and acupuncture therapies. Females were more likely to use CAM for treating abdominal pains, cold and flu, and cough than males (P < 0.000). Family members and friends (67.7%) were the main source of CAM usage, followed by television (10%), and Internet (8%). Religious and medicinal herb healers were the CAM healers most commonly visited by adolescents. Nearly 21-43% of adolescents had positive attitudes toward CAM, with some significant differences between males and females. It can be concluded that CAM is widely used by Saudi adolescents, but caution should be exercised for the safe usage of some CAM treatments. CAM should not be ignored; however there is an urgent need to establish regulations for CAM usage. PMID:25560362

    OBJECTIVES: To compare the perceptions of physician executives and clinicians regarding ethical issues in Saudi Arabian hospitals and the attributes that might lead to the existence of these ethical issues. DESIGN: Self-completion questionnaire administered from February to July 1997. SETTING: Different health regions in the Kingdom of Saudi Arabia. PARTICIPANTS: Random sample of 457 physicians (317 clinicians and 140 physician executives) from several hospitals in various regions across the kingdom. RESULTS: There were statistically significant differences in the perceptions of physician executives and clinicians regarding the existence of various ethical issues in their hospitals. The vast majority of physician executives did not perceive that seven of the eight issues addressed by the study were ethical concerns in their hospitals. However, the majority of the clinicians perceived that six of the same eight issues were ethical considerations in their hospitals. Statistically significant differences in the perceptions of physician executives and clinicians were observed in only three out of eight attributes that might possibly lead to the existence of ethical issues. The most significant attribute that was perceived to result in ethical issues was that of hospitals having a multinational staff. CONCLUSION: The study calls for the formulation of a code of ethics that will address specifically the physicians who work in the kingdom of Saudi Arabia. As a more immediate initiative, it is recommended that seminars and workshops be conducted to provide physicians with an opportunity to discuss the ethical dilemmas they face in their medical practice.

    Aim: Increasing alcohol consumption in many countries is an important cause of cancer worldwide. The aim of this study was to evaluate the burden of tobacco use and alcohol consumption and its related perception among population of Hail, Saudi Arabia. Methodology: A cross-sectional survey from March to April 2012 covering 451 participants, in the city of Hail, Northern Saudi Arabia. Results: Out of 451 respondents, 355(78.7%) were male and 96 (21.3%) were female giving a male to female ratio of 3.7:1. The age range of respondents was 11 – 77 years with a mean of 32 years. Prevalence of tobacco use and alcoholic beverages consumption were 30.3% and 7.5%, respectively. Most of the tobacco users and alcohol consumers showed positive knowledge concerning the relation between tobacco use and/or alcohol consumption and cancer. Conclusion: It is evident that the prevalence of tobacco consumption is rising in the Hail region. Female participation in tobacco and alcohol related studies in the Hail – Saudi Arabia represent a major obstacle since it is considered as social stigma due to complete prohibition by law.

    Objectives: To explore the spectrum of pathologies diagnosed in prostatic biopsies of Saudi men, and test whether the frequency of diagnosing the malignant fraction has been changed over the last 15 years, and assess the association between chronic inflammation (CI) with both benign prostatic hyperplasia (BPH) and cancer (PCa), and investigate the histological findings of cases presented with acute urinary retention (AUR) clinically. Methods: This is a retrospective cohort study including all prostatic biopsies accessed in the files in the Surgical Pathology Laboratory of King Fahd University Hospital, Alkhobar, Kingdom of Saudi Arabia over 15 years (1999-2013) for Saudi men. Age, procedure indication, and final diagnoses were retrieved and slides were reviewed. Results: There were 360 cases included in this study with a median age of 65 year-old. The BPH comprised the most (64.7%), while PCa accounted for 89 cases, 13.5% of which were incidental. Most cases of both BPH and PCa were diagnosed in the seventh decade. The frequency of diagnosing PCa did not show a solid rise or fall over time. Chronic inflammation is more related to BPH than to PCa. Only CI showed a significant statistical association with AUR. Conclusion: Prostatic diseases show a stable trend over time. While CI is a common dominator for both BPH and PCa, it is associated more with BPH. Among all histological findings, only CI is related to the clinical presentation of AUR. PMID:26593165

    Flowering times of plants are important life-history components and it has previously been hypothesized that flowering phenologies may be currently subject to natural selection or be selectively neutral. In this study we reviewed the evidence for phenotypic selection acting on flowering phenology using ordinary and phylogenetic meta-analysis. Phenotypic selection exists when a phenotypic trait co-varies with fitness; therefore, we looked for studies reporting an association between two components of flowering phenology (flowering time or flowering synchrony) with fitness. Data sets comprising 87 and 18 plant species were then used to assess the incidence and strength of phenotypic selection on flowering time and flowering synchrony, respectively. The influence of dependence on pollinators, the duration of the reproductive event, latitude and plant longevity as moderators of selection were also explored. Our results suggest that selection favours early flowering plants, but the strength of selection is influenced by latitude, with selection being stronger in temperate environments. However, there is no consistent pattern of selection on flowering synchrony. Our study demonstrates that phenotypic selection on flowering time is consistent and relatively strong, in contrast to previous hypotheses of selective neutrality, and has implications for the evolution of temperate floras under global climate change.

    Overweight and obesity are now a global epidemic, with more than one in five people qualifying as obese worldwide. These conditions are accompanied by excessive rates of non-communicable diseases (NCDs) related to overweight, like type 2 diabetes mellitus, hypertension, and cardiovascular diseases. Saudi Arabia, which has become increasingly westernized over the past few decades now has one of the highest prevalence rates of overweight and obesity, even in children. This puts the population at great risk for increased rates of NCD mortality. Competing cultures is partly to blame, as the combination of persisting traditional Saudi cultural practices, modern cultural changes, and economic prosperity has created an obesogenic environment that promotes unhealthy eating, sedentary lifestyles, and weight gain. Overweight and obesity are more prevalent in Saudi women than in Saudi men. Interventions targeting the environment are needed in order to promote greater health through healthy eating decisions and increased physical activity or exercise (especially for women).

    The purpose of this paper is to discuss the Saudi experience in implementing Electronic Lab Information Exchange (ELIE) within healthcare organizations in Saudi Arabia. This paper reviews the benefits, challenges and achievements that Saudi Arabia has gone through over the last five years in implementing ELIE. Data sources included academic literature, websites, and informant interviews. Results show that various Saudi healthcare organizations are participating in ELIE and improvements in laboratory department workflow and patient care have been reported. Future work includes projects to be implemented in different laboratories within the Kingdom to link the various laboratory information systems to Electronic Health Records. Various challenges stand in the way of implementing ELIE including weakness of the information infrastructure, staff resistance, recruiting qualified staff to develop and implement ELIE, producing clear policy and procedures to ensure staff compliance with the data entry, ensuring the privacy and integrity of patient data, and the lack of awareness on the importance of ELIE.

    The purposes of this quantitative, descriptive study were to investigate Saudi science teachers' beliefs about science and science teaching, and to determine how do Saudi science teachers view educational reform in science and how do they view change in education. In addition, the study sought to establish whether Saudi science teachers would be able to participate in implementing science education reform in Saudi Arabia. A questionnaire was used to collect data, addressing personal characteristics of the participant, teachers' beliefs about science and nature, about school science, about teacher - student relations in the classroom, and environmental factors affecting teaching science. Finally, the questionnaire ended with three open-ended questions about teacher's belief regarding: science and nature, teaching science, and reforming science curriculum. The sample was 329, consisting of 298 science teachers and 31 supervisors. The data were analyzed using SPSS (Statistical Package for the Social Studies). The data are analyzed and reported in percentages, means, standard deviations, and frequencies. The responses to open-ended questions were analyzed using the qualitative method. The responses were categorized in subsets using the coding method. Based on the review of the literature and the findings of this research, it was apparent that differences exist between teachers' beliefs about science and teaching and their teaching methods. Although Saudi science teachers presented inquiry-based views about science, nature, and teaching science, they do not practice these views in science class. The findings of the study imply that educational reform in science education must simultaneously address all the components of an educational system and the concept of systemic reform, as will as the need for a standards-based learning system and establishing Benchmarks for science in Saudi education. The conclusions of the study indicated that a curriculum reform project needs
