Disability in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Disability is a complex, influential, dynamic, multidimensional challenge, and it can substantially limit major life activities of human beings and their ability to integrate/reintegrate into society. According to the World Health Organization reports almost 15% of the world’s population lives with certain types of disability, of whom 2-4% experience substantial difficulties in functioning. In Saudi Arabia, very limited research has been conducted on the prevalence and incidence of disability, and most of this is on disabled children. There are several difficulties associated with conducting research on disability related issues in Saudi Arabia. Here, we review the current situation of disability, disability research, and rehabilitation in Saudi Arabia from the published literature.

Smoking in Saudi Arabia.  

Directory of Open Access Journals (Sweden)

This article reviewed the literature on the epidemiology, consumption, trade, control, prevention, and treatment of tobacco smoking in Saudi Arabia. The prevalence of current smoking in Saudi Arabia ranges from 2.4-52.3% (median = 17.5%. Among school students, the prevalence of current smoking ranges from 12-29.8% (median = 16.5%, among university students from 2.4-37% (median = 13.5%, and among adults from 11.6-52.3% (median = 22.6%. In elderly people, the prevalence of current smoking is 25%. The prevalence of smoking in males ranges from 13-38% (median = 26.5%, while in females it ranges from 1-16% (median = 9%. To conclude, smoking is prevalent in the Saudi population at different age groups. The prevalence of current smoking is much higher in males than in females at different ages. More research is needed in the area of prevention and treatment of smoking.

Diphyllobothriasis in Saudi Arabia.  

Directory of Open Access Journals (Sweden)

We described a Saudi patient infected with Diphyllobothrium latum D. latum. A 38-year-old male presented, complaining of passing worms. He had a history of recent travel to Europe and South East Asia. Stools examination revealed typical D. latum eggs. He was treated with praziquantel followed by saline purge, after which he discharged an intact tapeworm. Macroscopic and microscopic examinations of the worm confirmed the diagnosis of D. latum. This is the first case of diphyllobothriasis to be reported in Saudi Arabia. The epidemiology and methods of prevention of diphyllobothriasis are discussed.

Brucellosis in Saudi Arabia.  

Science.gov (United States)

This paper describes the history of brucellosis and the current public health picture in the Kingdom of Saudi Arabia. Health protection is made more difficult by several factors: (a) the local custom of drinking raw and warm milk of sheep, goats, and camels, (b) the animal reservoir of infection in the country complicated by importation of live animals both for sacrifice during Haj periods and to increase commercial flocks, and (c) by uncontrolled movements of humans and stock across political borders.

Hypertension in Saudi Arabia.  

Directory of Open Access Journals (Sweden)

Hypertension is increasing in prevalence in KSA affecting more than one fourth of the adult Saudi population. We recommend aggressive management of hypertension as well as screening of adults for hypertension early to prevent its damaging consequences if left untreated. Public health awareness of simple measures, such as low salt diet, exercise, and avoiding obesity, to maintain normal arterial blood pressure need to be implemented by health care providers.

Urbanization: Riyadh, Saudi Arabia  

Science.gov (United States)

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. The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif.

Stroke in Saudi children  

International Nuclear Information System (INIS)

To describe the epidemiology and clinical features of stroke in a prospective and retrospective cohort of Saudi children and ascertain the causes, pathogenesis, and risk factors. The Retrospective Study Group (RSG) included children with stroke who were evaluated at the Division of Pediatric Neurology, or admitted to King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the period July 1992 to February 2001. The Prospective Study Group (PSG) included those seen between February 2001 and March 2003. During the combined study periods of 10 years and 7 months, 117 children (61 males and 56 females, aged one month-12 years) were evaluated; the majority (89%) of these were Saudis. The calculated annual hospital frequency rate of stroke was 27.1/100,000 of the pediatric (1month-12 years) population The mean age at onset of the initial stroke in the 104 Saudi children was 27.1 months (SD=39.3 months) median and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). Large-vessel infarcts (LVI, 51.9%) were more common than small-vessel lacunar lesions (SVLL, 19.2%). Five patients (4.8%) had combined LVI and SVLL. Intracranial hemorrhage was less common (18.2%), whereas sinovenous thrombosis was diagnosed in 6 (5.8%) patients. A major risk factor was identified in 94 of 104 (89.4%) Saudi children. Significantly more hematologic disorders and coagulopathies were identified in the PSG compared thies were identified in the PSG compared to the RSG (p=0.001), reflecting a better yield following introduction of more comprehensive hematologic and cogulation laboratory tests during the prospective study period. Hematologic disorders were the most common risk factor (46.2%); presumed perinatal ischemic cerebral injury was risk factor in 23 children (22.1) and infectious and inflammatory disorders of the circulatory system in 18 (17.3%). Congenital and genetic cerebrovascular anomalies were the underlying cause in 7 patients (6.7%) and cardiac diseases in 6 (5.8%). Six patients (5.8%) had moyamoya syndrome, which was associated with another disease in all of them. Inherited metabolic disorders (3.8%) included 3 children with Leigh syndrome and a 29-months-old girl with mitochondrial encephalomypathy, lactic acidosis, and stroke-like episodes. Systemic vascular disease was a risk factor in 3 children (2.9%) including 2 who had hypernatrmic dehydration; and post-traumatic arterial dissection was causative in 3 cases (2.9%). Several patients had multiple risk factors, whereas no risk factor could be identified in 11 (10.6%). Due to high prevalence and importance of multiple risk factors, a comprehensive investigation, including hematologic, neuroimaging and metabolic studies should be considered in every child with stroke.

Radon in Saudi houses  

International Nuclear Information System (INIS)

A total of 637 passive radon dosemeters (CR-39 nuclear track detectors in a closed chamber) were used in a survey in 400 houses in Saudi Arabia. The radon concentration was found to vary from 5 to 36 Bq.m-3 (0.13 to 0.98 pCi.l-1) with a mean of 16 Bq.m-3 (0.43 pCi.l-1). The unoccupied houses showed a concentration of 29+-7 Bq.m-3 (0.78+-0.19 pCi.l-1) double that of the occupied houses, 14+-1 Bq.m-3 (0.39+-0.02 pCi.l-1), in the same area. The radon daughter concentration measured with a Working Level monitor in 17 unoccupied houses was found to vary from 1.35x10-3 to 24x10-3 WL with an average of 6.9+-1.4x10-3 WL. The average exhalation rate measured in 37 houses by 95 passive detectors in cans sealed to the walls ranged from 0.013 to 0.044 Bq.m-2.h-1(0.35 to 1.2 pCi.m-2.h-1) with an average of 0.021+-0.003 Bq.m-2.h-1(0.56+-0.09 pCi.m-2.h-1). This survey is the first in Saudi Arabia (a hot climate) and can usefully be compared with similar surveys in countries with cold climates. (author)

Rock Art of Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available It is not only oil in which Saudi Arabia is rich, but it is also among the four richest rock art regions of the world. Hundreds and thousands of petroglyphs, painted rock art, and ancient Arabian inscriptions sites are located all over the country, representing various cultural phases, from the Neolithic until the recent past. One can see the naturalistic, schematic, abstract, mythical, and mystical images representing ancient ideology, thoughts about the metaphysical world, religious entity, economy, environment, human activities, and variety of animal types, according to particular climatic and environmental conditions. The rock art of Saudi Arabia is the mirror of its rich cultural heritage of so-called Bedouin or desert dwellers that surprises the world with its 4000 archaeological and more than 1500 rock art sites.

These newly recorded species are mostly inhabit the mountains and the wadies as well as in the areas characterized by the great variations in temperature. The appearance of these species may be due to the rapid change in the ecological factors which leeds to the movement of the vegetation, or due to the uncomplete, previous survey of the flora. This study was pointed the need of more ecological studies to know the reasons of the change in the flora and to study how much the ecological stress may affect the speciation.

Rotavirus infection in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Human rotavirus, an important causative agent of severe gastroenteritis in infants and young children worldwide, leads to high morbidity in both developing and developed countries, including Saudi Arabia, and high mortality in developing countries. Effective control depends upon an accurate understanding of disease burden and the relative importance of circulating serotypes. Methods: We examined the epidemiology and disease burden of rotavirus in Saudi Arabia through a review of 22 published studies of rotavirus and the aetiology of diarrhoea carried out from 1982 to 2003. Results: The prevalence of rotavirus infection ranged between 10% to 46% with a median of 30%. Most cases were among children less than 2 years of age, and particularly in the first year of life. There were significant differences in seasonality within Saudi Arabia, with increased infection during winter in some cities and during summer in others. G1 was the predominant serotype followed by G4, G3 and G2, in 4 studies where strains had been G-typed. The prevalence of nontypeable strains ranged from 11.0% to 31.3%. No data were available on P types. Results of electropherotyping in 4 studies revealed that the long electropherotype was predominant. Conclusion: Rotavirus is an important cause of severe diarrhoea in Saudi children. However, the available data on rotavirus strains in circulation are limited and there is an urgent need for up-to-date and comprehensive studies to evaluate rotavirus strains in circulation and identify unusual types that could be incorporated into future vaccines.

The Saudi Initiative for asthma  

Directory of Open Access Journals (Sweden)

Full Text Available 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.

Saudi Arabia plans future strategy  

International Nuclear Information System (INIS)

The future strategy of Saudi Arabia with respect to its oil production capacity is discussed. A major uncertainty affecting planning is the prospect of an Iraqi return to the market as and when Saddam Hussein falls or he manages to comply fully with all the UN resolutions and sanctions are lifted. It is believed that Iraq could at very short notice be capable of exporting 2mb/d of crude rising to 2.5 mb/d within a few months. This is 10% of OPEC's physically traded crude. Also taken seriously are Baghdad's assertions that Iraq will have a production capacity of about 6mb/d by the year 2000. Saudi officials are concerned that OPEC is not ready to tackle the impact of an Iraqi return to the market at a time when some OPEC members are producing above quota anyway. The most likely outcome is thought to be that OPEC would simply raise their nominal production ceiling. Against this background, Saudi Arabia has embarked on the exploitation of the gigantic oil reserves of the Shaybah field. This development offers the kingdom an ability, on the one hand, to increase its earnings while remaining within its OPEC quota and, on the other hand, to increase output substantially should it ever appear that its best interests are served by not adhering to quotas.

Cephalometric norms for saudi adults living in the western region of Saudi Arabia.  

Science.gov (United States)

European-American norms are still used in the orthodontic treatment of Saudi patients, despite the different ethnic backgrounds of Saudis. The aims of this study were to evaluate the cephalometric features of a Saudi population and to establish cephalometric norms for Saudis living in the western region of Saudi Arabia. Seventy lateral cephalometric radiographs of Saudis (32 females and 38 males; aged 18-28 years) with acceptable profiles and Class I dental relationships were traced and analyzed. The mean value, standard deviation, and range of 16 angular and linear variables were calculated. The resulting norms for Saudis were compared with European-American norms using an independent t-test. Male and female groups were also compared using the t-test. Saudis tend to have an increased ANB angle because of retrognathic mandibles and bimaxillary protrusion as compared with European-Americans. Males tend to have more prognathic mandibles than females as indicated by the statistically significant increase in facial angle (P < .05) and SNB angle (P < .05). Although the anterior lower face height was similar in males and females, males tend to have a steeper mandibular plane angle when related to the anterior cranial base than females (P < .05). Saudis have distinct cephalometric features, which should be used as a reference in treating Saudi orthodontic patients. PMID:16448278

Reading Strategy Instruction in Saudi Schools  

Directory of Open Access Journals (Sweden)

Full Text Available This study explores the attitudes of Saudi EFL teachers toward explicit instruction of readingstrategies. The study also compares actual practices of Saudi teachers with their beliefs and attitudes towardreading strategy instruction. In this study, quantitative data were collected using an attitude questionnaire,while qualitative data were collected using observation and semi-structured interviews. The quantitative dataobtained were analyzed by using means, standard deviations, and the Pearson product-moment correlationcoefficient. Qualitative data from a semi-structured interview were also analyzed to explore teachers'knowledge about reading strategy instruction. The results of this study show that Saudi teachers believestrongly in the importance of cognitive reading strategies and that they have insufficient knowledge of theimportance of metacognitive reading strategies. The study ends with recommendations for training Saudi EFLteachers in some of the most effective metacognitive reading strategies to help students plan, monitor, evaluate,and regulate their learning.

Trajectory analysis of Saudi Arabian dust storms  

Science.gov (United States)

Temporal and spatial characteristics of Saudi Arabian dust storms, with focus on associated air parcel trajectories, are investigated using station and gridded weather observations and remotely-sensed aerosol optical depth (AOD). For 13 focal stations, an extensive pool of 84-h backward trajectories is developed for dust storm days, and the trajectories are grouped into 3-5 representative clusters based on the K-means technique and Silhouette Coefficients. Saudi Arabian dust storms are most prominent during February-June, with a mid-winter peak along the southern coast of the Red Sea, spring peak across northern Saudi Arabia around the An Nafud Desert, and early summer peak in eastern Saudi Arabia around the Ad Dahna Desert. Based on backward trajectories, the primary local dust source is the Rub Al Khali Desert and the primary remote sources are the Saharan Desert, for western Saudi Arabia, and Iraqi Deserts, for northern and eastern Saudi Arabia. During February-April, the Mediterranean storm track is active, with passing cyclones and associated cold fronts carrying Saharan dust to Saudi Arabian stations along the northern coast of the Red Sea. Across Saudi Arabia, the highest AOD is achieved during dust storms that originate from the Rub Al Khali and Iraqi Deserts. Most stations are dominated by local dust sources (primarily Rub Al Khali), are characterized by three dominant trajectory paths, and achieve AOD values exceeding 1. In contrast, for stations receiving predominantly remote dust (particularly Saharan), 3-5 trajectory paths emerge and AOD values only reach approximately 0.6 as dust is lost during transport.

High prevalence of osteoporosis in Saudi men  

International Nuclear Information System (INIS)

Objective was to determine the prevalence of osteoporosis in healthy Saudi men. We randomly recruited 429 Saudi men from the community. The recruited Saudi men were subjected to an interview to reveal their lifestyle parameters, calcium intake and level of activity. Bone densitometry was assessed at lumbar spine (L-4) and the femoral neck. The dual x-ray absorptiometry (DXA) scan was carried out in the Nuclear Medicine at King Khalid University Hospital, Riyadh, Saudi Arabia from September 2002 to December 2004. The World Health Organization definition of low bone mineral density was used. Poor oral calcium intake and low level of daily activity were noted. The overall prevalence of osteopenia for the lumbar spine in the whole group was 35.7% while osteoporosis was present in 21.4% of the subjects. In the femoral neck, osteopenia was noted in 38% and osteoporosis in 11.4%. When either lumbar spine or femoral neck osteoporosis is used for diagnosis, the prevalence of osteoporosis rises to 23.5%. Within the whole group, osteopenia and osteoporosis were more common in individuals above the age of 50 than those below 50 years old. Low bone mineral density occurs with high frequency in Saudi men. Lumbar spine appears to be affected to a higher degree. The reason for the high prevalence of osteoporosis in Saudi men is unclear. Possible underlying causes include nutritional, life style and genetic factors. (author)

Saudi decree encourages MTBE, Chevron aromatics plant  

International Nuclear Information System (INIS)

Chevron Chemical (Houston), encouraged by a new Saudi royal decree that establishes extremely low feedstock prices, is in final negotiations to build a novel aromatics plant in Saudi Arabia. Chevron says it plans to close the deal and announce details the first week of March. The unit will be based on Chevron's Aromax reforming process, which uses a zeolite catalyst to convert light naphtha into benzene and toluene. No existing plant is using the technology, but Chevron is building a $250-million, 150-million gal/year Aromax unit at its refinery site in Pascagoula, MS, and Idemitsu has licensed the process for a plant in Chiba, Japan. The Saudi decree, issued late last year, pegs domestic feedstocks - propane, butane, and naphthas - at 30% below the lowest price of the prior quarter in major non-domestic markets. That clarifies and guarantees the Saudi feedstock price, which has always been nebulous, and thus allows project feasibility to be more clearly assessed. The decree is designed to encourage further private petrochemical investment in the country. In particular, the Saudi government hopes guaranteed low prices for butane will encourage more methyl tert-butyl ether (MTBE) projects. Arabian American Chemical, a 50/50 joint venture between Mobile and Arabian Chemical Investments, said in October of last year that its 830,000-m.t./year MTBE project at Yanbu, Saudi Arabia, would go ahead if feedstock questions could be resolved. The decree apparently resolves those questions

Saudi sands, SCUDS, and survival.  

Science.gov (United States)

SCUD attacks were one of many challenges this pediatric nurse practitioner (NP) and Air Force Reserve flight nurse faced daily during Desert Shield and Desert Storm. Providing nursing care to sick and injured patients on board a C141 transport plane en route from Saudi Arabia to Germany was her primary responsibility. Additionally, many hours were spent filling sandbags, attending in-service classes, and practicing putting on a gas mask and protective suit. Although the war has been over for almost 3 years, the effects are long lasting. The author was able to use her wartime experience positively to gain insight into survival in today's violent society. As violence increases, NPs must reshape their focus and educate their clients about survival. PMID:8297671

The incidence of leukemia in Saudi Arabia. Descriptive epidemiological analysis of data from the Saudi Cancer Registry (2001-2008  

Directory of Open Access Journals (Sweden)

Full Text Available To describe the epidemiological data of leukemia cases diagnosed from 2001 to 2008 among male and female Saudis, including the frequency and percentage of cases, the crude incidence rate (CIR, and the age-standardized incidence rate (ASIR stratified by leukemia subtype, region, and year of diagnosis.Methods: This is a retrospective descriptive epidemiological analysis of all Saudi leukemia cases recorded in the Saudi Cancer Registry (SCR between January 2001 and December 2008. The study was carried out in 2013 to investigate the pattern of leukemia in the Saudi population. Descriptive statistics and Poisson regression model were used. Results: A total of 3852 leukemia cases were registered in the SCR between January 2001 and December 2008. The region of Riyadh, Saudi Arabia had the highest overall ASIR among Saudi males at 5.2 per 100,000 males, followed by both the Eastern region and Northern region at 4.9 per 100,000 males. Furthermore, the region of Najran recorded the highest overall ASIR among Saudi females at 4.5 per 100,000 females. However, Jazan had the lowest average ASIRs of leukemia in Saudi Arabia. Conclusion: There was a slight increase in the CIRs and ASIRs of leukemia in Saudi Arabia between 2001 and 2008. Riyadh, the Eastern region, and the Northern region had the highest overall ASIRs of leukemia among Saudi males, and Najran had the highest overall ASIRs of leukemia among Saudi females; while Jazan had the lowest rates among the Saudi population.

Real Exchange Rate Misalignment in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available This paper attempts to measure degree of misalignment of the Saudi Riyal by estimating the long run equilibrium real exchange rate of the currency. Based on cointegration technique, this paper has identified, government consumption expenditure, GDP growth and gross capital formation as important determinants of the Saudi Riyal long run equilibrium value. Results suggest that the actual real exchange rate was below the estimated equilibrium (Saudi Riyal over valued in 1980,198 1and 1982 by 25%, 16% and 7% respectively. Following 1983, the Saudi real exchange rate rose above the equilibrium exchange rate thus starting an era of undervaluation of the Saudi currency that lasted until the year 2009.The downward slide began in 1983 when the riyal fell below its equilibrium exchange rate by 1% with the declining trend deteriorating further to 10% in 1984, 19% percent in 1985, 27% in 1986 and so on until it hit an all-time low of 84 percent below estimated equilibrium in 2006. Thereafter, the decline started receding gradually with the misalignment below exchange rate equilibrium improving to about 80 percent in 2009.

Carotid Plaques in Saudi Smokers  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Smoking has been found to be associated with carotid atherosclerotic disease. Since smoking is an important public health problem, because it may be an essential risk factor for carotid artery plaques. Therefore the researchers tried to explore the powerful of this association, the researchers investigated smokers as unique suspected risk factor for carotid plaques beside the age. Methods: In observational cross-sectional study, 31 smokers with mean age of 56, were studied by B- mode ultrasound. Carotid arteries for all participants were examined by using 7MHrz linear transducer. Both saggital and transverse views were applied to evaluate the right and left common carotid arteries. Results: The frequency of carotid plaque was 35.5%. 54.5 % of these occurred in population group that smoke > 20 cigarettes per day. All plaques were presented in population of age above 53 years old. There was association between smoking frequency and age with the increases of plaque size. Conclusion and recommendations: The study suggested that there is a significant association between carotid plaques and smoking in Saudi smokers. In addition it showed that carotid plaque may present at age of 54 years old in smokers. The researchers recommended that further studies were needed. Moreover intensive health promotion against smoking in the KSA. represents an essential issue.

Saudis study native bacteria for MEOR  

Energy Technology Data Exchange (ETDEWEB)

Bacteria isolated from three Saudi crude oils were tested for possible use in enhanced recovery projects in the Safaniya field. The bacterial strain that exhibited the lowest interfacial tension while creating the least permeability damage and the highest oil recovery was isolated from Khafji crude from the Marjan field. Although the use of microorganisms for EOR purposes has been studied and tested for many years, the specific mechanisms involved are not fully understood. MEOR systems must be custom designed for specific reservoir conditions, crude oils and microbial-nutrient systems. This paper reviews the various research going on with the various bacterial strains to be used in MEOR in Saudi Arabia.

Petroleum production in Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

Oil exploration in Saudi Arabia began in September 1933, and test drilling in 1934. Annual commercial production averaging 100,000 bbl/day started in 1938 from Damman oil field. Abquaiq and Quatif fields tacked on 200,000 and 5,000 bbl/day in 1941 and 1945, respectively. Production increased to more than 246,000 bbl/day in 1947, reached 300,000 by 1948 and jumped to 500,000 in 1949. Safaniya, the world's largest offshore reservoir, and Ghawar, the world's largest onshore oil field, were discovered in 1951 and 1954 consecutively. Among other notable fields, Khursaniyah, Khurais, and Manifa were discovered, the first in 1956, and the rest in 1957 successively. Berri, a reservoir which underlies both land and water, was divested in 1964. The Kingdom reached its 9.9 million bbl/day production peak in 1980, and has shrunk to its prevalent 4.34 million bbl/day Opec quota level. The proven oil reserves have risen by 85 billion bbl to 255 billion in January following a six year study. With additional development and exploration, the remaining reserves could be as high as 313 billion bbl of oil. During most of its geologic history, the producing area protracted between the Arabian shield and Tethyan seaway. The principal reservoir beds are composed of four members of the productive Arab Formation that expound quadruple major cycles of porous calcarenitic limestones and dolomites alternating with impervious evaporitic cap rocks favorably located on the foreland shelf. The area is characterized by structural traps with maximum oil-filled closure of about 1,300 feet. Crude oil export output appears certain to rise again this year to meet world demand.

Saudi experience with classic homocystinuria  

International Nuclear Information System (INIS)

Classic homocystinuria is an autosomal recessive disorder due to cystathionine beta-synthase deficiency. The clinical, radiological and neurophysiological findings of classic homcystinuria diagnosed at King Faisal Specialist Hospital and Research Centre (KFSH and RC) are presented in this report. Twenty-four patients (15 females and 9 males) were referred to KFSH and RC for work-up of mental retardation, seizures, thrombo-embolic episodes and dislocation of the ocular lenses. The common clinical findings included ectopia lentis (20 patients), skeletal system involvement (18 patients), vascular system involvement (9patients), and mental retardation (all patients to varying degrees). Unusual findings consisted of a patient who developed severe lower gastrointestinal bleeding, a patient with insulin-dependent diabetes mellitus, probably due to vasculopathy, and other having severe bronchiectasis, which may have been due to fibrillin disruption, and required the resection of a lobe of lung. The parents of 21 patients were first-degree relatives, and 19 patients had one or more family members affected by the same disease. All patients had markedly elevated plasma levels of methionine. Cystathionine synthase activity in the fibroblast was measured in 25% of the patients and was deficient. Only four patients responded to pyridoxine and their methionine level decreased to almost normal range. The aim of this study was to increase the awareness of this disease in the scientifiawareness of this disease in the scientific and medical community, in particular in the general pediatrician working in Saudi Arabia who first encounters the clinical manifestations of disease. Early detection through tandem mass spectrometry of blood spot screening and treatment are important and may prevent the major complications of this disease. (author)

Extra-pulmonary tuberculosis in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Studies from developed countries have reported that extra-pulmonary tuberculosis (EPTB is on the rise due to the human immunodeficiency virus (HIV epidemic. However, similar studies from high-burden countries with low prevalence of HIV like Saudi Arabia are lacking. Therefore, we conducted this study to investigate demographic and clinical characteristics of patients with pulmonary and extra-pulmonary tuberculosis. A retrospective analysis was carried out on all patients (n=431 with a culture - proven diagnosis of tuberculosis seen at University teaching hospital, Riyadh, Saudi Arabia from January 2001 to December 2007. A total of 183 (42.5% pulmonary tuberculosis (PTB and 248 (57.5% extra-pulmonary TB (EPTB cases were compared in terms of age, sex, and nationality. There were 372 Saudis (SA (86.3% and the remaining non-Saudis (NSA 59 (13.7%. The age distribution of the PTB patients had a bimodal distribution. EPTB was more common at young age (20-29 years. The proportion of EPTB cases was significantly higher among NSA patients (72.9% compared to SA patients (55.1%. Females had higher proportion (59.5% of EPTB than males (55.6%. The most common site was lymph node tuberculosis (42%. In conclusion, our data suggest that EPTB was relatively common in younger age, female gender and NSA. Tuberculosis (TB control program may target those populations for EPTB case-finding.

Saudi Arabia's oil policy  

Energy Technology Data Exchange (ETDEWEB)

Saudi Arabia's oil policy is based on support for the Imperial rule, and a strategy of minimal risk takes first priority. This country with vast oil resources is characterized by a lower level of needed oil revenue because of its little population, by low producing cost, and by dependence on the American majors. Differing from other OPEC countries, Saudi have maintained moderate policy toward western developed countries: avoiding a sudden rise of oil prices, making best use of its vast oil resources, and consideration for the Third World, especially for Islamic countries. Through detailed analyses on seven periods, from 1973 until now, Saudi was proved to have a well-balanced sense on its oil policy and to have a fundamental attitude to avoid risk throughly. A stable price of oil with long-term competitiveness should be set in the future. Saudi's future oil policy is likely to be the control of OPEC contries'oil production to avoid a sudden rise of oil prices, and the oil production as much as its quota. (3 figs, 26 refs)

Medication administration errors in Eastern Saudi Arabia  

International Nuclear Information System (INIS)

To assess the prevalence and characteristics of medication errors (ME) in patients admitted to King Fahd University Hospital, Alkhobar, Kingdom of Saudi Arabia. Medication errors are documented by the nurses and physicians standard reporting forms (Hospital Based Incident Report). The study was carried out in King Fahd University Hospital, Alkhobar, Kingdom of Saudi Arabia and all the incident reports were collected during the period from January 2008 to December 2009. The incident reports were analyzed for age, gender, nationality, nursing unit, and time where ME was reported. The data were analyzed and the statistical significance differences between groups were determined by Student's t-test, and p-values of <0.05 using confidence interval of 95% were considered significant. There were 38 ME reported for the study period. The youngest patient was 5 days and the oldest 70 years. There were 31 Saudis, and 7 non-Saudi patients involved. The most common error was missed medication, which was seen in 15 (39.5%) patients. Over 15 (39.5%) of errors occurred in 2 units (pediatric medicine, and obstetrics and gynecology). Nineteen (50%) of the errors occurred during the 3-11 pm shift. Our study shows that the prevalence of ME in our institution is low, in comparison with the world literature. This could be due to under reporting of the errors, and we believe that ME reporting should be made less punitive so that ME can be studied and preventive measures implemented (Author)d preventive measures implemented (Author).

Thunderstorm distribution and frequency in Saudi Arabia  

Science.gov (United States)

A new average annual thunder day map for Saudi Arabia is presented. Based on this map, the distribution of thunderstorms over Saudi Arabia is analysed in terms of the factors related to the lightning performance of transmission lines such as thunderstorm days per year (Td/yr). Lightning activity continues for the present to be represented by thunderstorm frequency, which is routinely recorded at meteorological observation sites. Thunderstorm occurrence at a particular location is usually expressed as the number of days in a calendar year when thunder was heard, averaged over several years. This paper examines thunderstorm days in different areas of Saudi Arabia and specifically those areas where lightning strikes are more frequent; for this purpose, the software ArcGIS is used to produce contour maps which demonstrate areas of concern in Saudi Arabia in the period 1985-2003. Establishing the annual and seasonal Td/yr for Saudi Arabia enables transmission and distribution line engineers to calculate and better design a lightning protection system. Maps of thunder days/year (Td/yr) were constructed on the basis of the database records available on lightning incidence in Saudi Arabia at the Presidency of Meteorology and Environment (PME) (http://www.pme.gov.sa/). Annual thunderstorms are most frequent over the southwestern parts of the country, and generally decrease towards the west and east. Due to its low latitude and less temporal change, the west coast of the Red Sea recorded the lowest Td/yr. A secondary maximum Td/yr is apparent in the southeast to central part of the country. Thunderstorm frequency does not, in general, appear to vary in any consistent way with rainfall. There appears to be no evidence of any widespread temporal trend in thunderstorm frequency. The southern region in general, and especially the cities of Abha, Taif and Al-Baha, has shown greater numbers of thunderstorm days all year round. Similarly, this variation did show higher frequency throughout the year. The development of lightning incidence and the counting of Td/yr, as well as the establishment of annual and seasonal lightning maps of Saudi Arabia, are initiating a new era of producing and archiving thunderstorm maps and data records which serve the PME, the utilities, industry and the public.

Methods: This study was conducted on January 2013 at the Internal Medicine Department, Taif University, Taif, KSA. An online search was conducted on PubMed to collect the articles published from KSA using the country name (Saudi Arabia as a keyword. The search was limited to the studies published in the period of 2 years from January 2010 to December 2011. The year 2012 was not included to give at least one year for citation. The total number of studies during the stated period was compared with those published from other countries in the same period, and adjusted per population size. Impact factor and number of citations were used to assess the quality of the studies. Results: A total of 1905 published articles/studies were from KSA in the said period. Australia had the maximum number of studies (100% published per million population (1258.571+. The Kingdom of Saudi Arabia had 72.71 articles per million population, and was ranked 16th among the other countries. Most of the articles (65.3% were published from Riyadh followed by Jeddah (13.3%, and most of them were from the fields of Community Medicine (15.5%, Pathology (13.7%, Medicine (13.2%, and Surgery (13.1%. King Faisal Specialist Hospital in Riyadh had the highest impact factor with a mean of 2.74 ± 3.45. Conclusion: The Kingdom of Saudi Arabia is lagging behind in biomedical research.

Career profile of dentists in Saudi Arabia  

International Nuclear Information System (INIS)

The aims of the present survey were to determine whether differences existed between male and female dentists in Saudi Arabia in career development, positions occupied within their employment, and to analyze the effect of different variables on their career development in some of the provinces in Saudi Arabia. A self-conducted questionnaire was distributed among male and female dentists, general practitioners as well as specialists, working at several governmental hospitals in Saudi Arabia. The questionnaires consisted of 40 questions in the format of multiple choices and yes/no answer. Data were analyzed by gender with the significant difference level set at (P < 0.05). The response rate was 40.8% of which 51.9% were females and 48.1% males with 70% of them below 45 years of age. No significant difference was found between males and females in having higher education or additional degrees. The specialty that was highly reported among females was pedodontics and in males, orthodontics. Males were more likely to hold authorized administrative positions (63%), while females held administrative positions which were internally arranged by their departments (57%). Eighty-three percent of female respondents thought that there was favouritism towards males in appointment to administrative positions, while only 5.5% of male respondents reported that there was favouritism to females in occupying the same positions. There was no significant difference between male and female decant difference between male and female dentists in Saudi Arabia with respect to job opportunities, working hours and relationships with their colleagues. In addition, there is evidence of an intensifying determination of female dentists in Saudi Arabia, to pursue their chosen career while coping with the diverse demands of being a professional, a wife and mother.

Gender-segregated Education in Saudi Arabia: Its Impact on Social Norms the Saudi Labor Market  

Directory of Open Access Journals (Sweden)

Full Text Available This article examines the Kingdom of Saudi Arabia's gender-segregated higher education system and how it is used to transmit the Kingdom's traditional societal expectations to the employment sector. With Saudi Arabia's current need for economic change, the education system is retarding instead of accelerating reform. A background consisting of Saudi Arabian history, governing laws, religious beliefs and women's roles is examined. I then discuss the education system's preservation goal by considering segregation, women's mobility, videoconferencing courses, and the roles of professors. I attempt to explain how the current education system fails to prepare its students for the global economy: by limiting women's access to the labor market, and by not preparing men for the realities of the global market and therefore creating the need for migrant workers. In conclusion, conserving culture is significant, but for economic change to occur, the extent of cultural conservatism and its effect on the education system need to be re-evaluated.

Peaceful nuclear energy to Saudi Arabia  

International Nuclear Information System (INIS)

The argument for and against the application of peaceful nuclear energy in Saudi Arabia is discussed in terms of the country's industrial development and power requirement for electricity and desalination. The discussion leads to the conclusion that due to its large oil reserve, Saudi Arabia may tolerate a considerate approach to nuclear energy up to the year 2000. Beyond this date, nuclear energy should be used in order to achieve the desired industrial maturity in the country. The introduction of nuclear energy, however, will be faced with three constraints, namely man power availability, cooling water requirement, and the size of the electrical grid. The period 1980-2000 is thus most suitable for important preparation steps, among which are the adoption of regulatory provisions, establishment of nuclear facilities with necessary equipments, and staff training for regulatory, organizational, and technical activities. The paper outlines a scheme for the initiation steps and efforts to meet these requirements. (orig.)

Oral lesions in Saudi renal transplant patients  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Renal transplantation has evolved as the best treatment option for patients with end-stage renal disease. Different oral problems arise in these patients, either as a direct consequence of drug-induced immunosuppression or pharmacokinetics. To determine the prevalence of intra-oral lesions in a group of medically stable Saudi renal transplant patients (RTP) and to identify possible risk factors, in comparison with age and sex-matched healthy control subjects (HCS), we studied 58 RTP and 52 HC...

Motives for cosmetic procedures in Saudi women.  

Science.gov (United States)

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.

Social responsibility of the multinational corporations operating in Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

This dissertation explores the social responsibility of MNCs operating in Saudi Arabia (SA) and their social impact on Saudi society through survey research using both primary and secondary data. To furnish the reader with a better understanding of this subject, to develop the hypothesis to be tested, and to define NMCs and social responsibility, this author reviewed literature related to MNCs and social responsibility with specific reference to developing countries, particularly SA; described briefly the Saudi environment in which MNCs operate; and determined the number and type of MNCs and their activities in SA as reported in Saudi government records. The author examined the social responsibility of MNCs toward Saudi society by comparing the perception of MNCs' non-Saudi managers with Saudis (managers, government officials, and elite) regarding some specific issues (e.g., MNCs' concerns for profit versus public good); regarding some suggested programs (e.g., training); and through looking at the actual programs undertaken by MNCs (e.g., medical care). The study helped to understand better the nature of MNCs. It indicated that MNCs seem to be attracted to SA, that their number is greater than government records indicate, and that a large number of MNCs have Saudi nationality.

DETERMINANTS OF BIRTH SPACING AMONG SAUDI WOMEN  

Science.gov (United States)

Background: High fertility levels are of major concern to planners and policy makers in most countries in the developing world. In Saudi Arabia, the rate of population growth is the third highest of the countries of the Eastern Mediterranean Region. Objectives: This study aimed at identifying determinants of birth spacing and attitudes toward family planning among Saudi women. Methods: A cross sectional survey of all women who have been married before, aged 15-49 years attending Al Hada armed forces hospital (primary health care and antenatal care clinics), was conducted between 1st February 2005 and 31st January 2006. Data was collected on socio-demographic, biological characteristics, beliefs, attitudes, and utilization of family planning services, pregnancy intervals and medical history Results: For the 786 women included in the study, the mean duration of interbirth interval was 2.38±1.24 years. The multivariate Cox regression revealed that a woman's education, work status, husband's work status, a woman's history of chronic diseases, and husband's encouragement of interbirth spacing were the only significant predictors of longer interbirth intervals. Shorter interbirth intervals were independently predicted by lower family income, and presence of female offspring only or equal number of male and female offspring as opposed to presence of more males. The great majority of participating women (98%) had a positive opinion of the effect of birth spacing on the family. Conclusion: This study showed that certain factors were significant predictors of interbirth spacing for the Saudi women. This should lead to the encouragement of longer intervals between births. However, further studies are needed to ascertain a cause-effect association. PMID:23012155

Sexually transmitted infections in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Data on sexually transmitted infections (STIs in Saudi Arabia (SA and other Islamic countries are limited. This study describes the results of a five-year surveillance for STIs in SA. Methods This is a case series descriptive study of all confirmed STIs diagnosed in SA from January, 1995 through December, 1999. Results A total of 39049 STIs were reported to the Ministry of Health. Reported STIs included nongonococcal urethritis (14557 infections, 37.3%, trichomoniasis (10967 infections, 28.1%, gonococcal urethritis (5547 infections, 14.2%, syphilis (3385 infections, 8.7%, human immunodeficiency virus (2917 infections, 7.5%, genital warts (1382, 3.5%, genital herpes (216 infections, 0.6%, and chancroid (78 infections, 0.2%. The average annual incidence of STIs per 100,000 population for Saudis and non-Saudis, respectively, was as follows: 14.8 and 7.5 for nongonococcal urethritis, 9.4 and 10.4 for trichomoniasis, 5.2 and 4.2 for gonorrhea, 1.7 and 6.4 for syphilis, 0.6 and 8.0 for HIV, 1.4 and 0.7 for genital warts, 0.1 and 0.4 for genital herpes, and 0.1 and 0.1 for chancroid. The incidence of STIs was somewhat steady over the surveillance period except for nongonococcal urethritis which gradually increased. Conclusion Nongonococcal urethritis, trichomoniasis, and gonococcal urethritis were the most commonly reported STIs in SA. Even though the incidence of STIs in SA is limited, appropriate preventive strategies that conform to the Islamic rules and values are essential and should be of highest priority for policymakers because of the potential of such infections to spread particularly among the youth.

The Najd Fault System of Saudi Arabia  

Science.gov (United States)

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.

Assessing Volcanic Risk in Saudi Arabia  

Science.gov (United States)

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.

Cryptosporidiosis in Saudi Arabia and neighboring countries  

International Nuclear Information System (INIS)

Cryptosporidium is a coccidian protozoan parasite of the intestinal tract that causes severe and sometimes fatal watery diarrhea in immunocompromised patients and self-limiting but prolonged diarrheal disease in immunocompetent individuals. It exists naturally in animals and can be zoonotic. Although cryptosporidiosis is a significant cause of diarrheal disease in both developing and developed countries, it is more prevalent in developing countries and in tropical environments. We examined the epidemiology and disease burden of Cryptosporidium in Saudi Arabia and neighboring countries by reviewing 23 published studies of Cryptosporidium and etiology of diarrhea in between 1986 and 2006. The prevalence of Cryptosporidium infection in human's ranged from 1% to 37% with a median of 4%, while in animals it was for different species of animals and geographic locations of the studies. Most cases of cryptosporidiosis occurred among children less than 7 years of age and particularly in the first two years of life. The seasonality of Cryptosporidium varied depending on the geographic locations of the studies but it generally most prevalent in the rainy season. The most commonly identified species was Cryptosporidium parvum while C.hominis was detected only in one study from Kuwait. The cumulative experience from Saudi Arabia and four neighboring countries (Kuwait, Oman, Jordan and Iraq) suggest that Cryptosporidium is an important cause of diarrhea in human and cattle. However, the findings of this review also demonstrate the limitations of the available data regarding Cryptosporidium species and strains in circulation in these countries. (author)

Kawasaki disease in Western Saudi Arabia  

International Nuclear Information System (INIS)

To describe our experience on Kawasaki disease in the Madinah region, Kingdom of Saudi Arabia (KSA). This is a retrospective hospital based study. The study was conducted in Maternity and Children Hospital, Madinah, Kingdom of Saudi Arabia during January 2007 to January 2010. The study included 51 patients' records as suspected cases of Kawasaki disease. The study was approved by the Ethical Committee. Twenty-four patients were proven to have Kawasaki disease in this study. The mean age of the patients at diagnosis was 3.1+/-2.4 years. Most patients were younger than 5 years (83.3%). The male to female ratio was 1.7:1. Diagnosis was made 8.1+/-3.3 days after start of fever with a range from 4-15 days. All patients received intravenous immunoglobulin (IVIG) with 2 requiring another dose of IVIG. Echocardiography was performed 10.1+/-3.9 days from onset of fever with a range of 4-20 days. The duration of hospital stay was 7.9+/-5.8 days with a range from 3-25 days. Three patients had coronary artery abnormalities and still have coronary artery dilatation at last follow-up appointment. A high index of suspicion is mandatory for early diagnosis of Kawasaki disease as delayed diagnosis may lead to coronary lesions. A national awareness program on Kawasaki disease is recommended (Author).

Indonesians in Saudi Arabia: Worhsip and Work  

Directory of Open Access Journals (Sweden)

Full Text Available This article, which  opens a new  line of research,  is intended  to make a first assessment of the consequences  of Indonesian migration to saudi Arabia,  in particular  during  the  first half of the 2Oth century-a period when the immigration is bound  up with the pilgrimage from which Saudi Arabia draws a large part of its revenues. It must be added  that while documentary  evidence and partial studies on  this period  exist,  it turns out that documentation on the contemporary period  is scarce. This article also  is concerned with describing the evolution  of certain striking  aspects of the close  relation  between  the pilgrimage to Mecca  and Indonesian migrants  looking  for work.  We need to consider  the methods  of hiring  labor,  the networks  involved  in recruiting it, the organization  of travel,  as well as the increasing indebtedness  of the migrants  through  intermediaries  who, more and more professionally, arrange  these attempts  to live abroad, prompted in many cases by the same desire  for wealth.Copyright (c 2014 by SDI.

Liver size in Saudi Children and adolescents  

International Nuclear Information System (INIS)

To examine the liver size in Saudi children and adolescents. A large sample of children was selected from the general population by multistage random probability sampling for the assessment of physical growth. A random subsample of children-newborns to 18 years old-was taken from this larger sample for this study. Liver size below the costal margin and liver span along the midclavicular line were determined by physicians. Data were analyzed using SPSS software and medians and standard deviations were calculated. Between 2004 and 2005, 18 112 healthy children up to 18 years of age were examined. All were term and appropriate for gestational age. There were 9 130 boys and 8 982 girls, yielding a nearly 1:1 male to female ratio. The maximum palpable liver size below the costal margin was 2.4 cm. The median and + 2 SD liver span at birth were 4 and 6.9 cm, respectively. There was no difference in the liver span between boys and girls of up to 60 months of age. Thereafter, a difference could be seen increasing with age, with girls having smaller liver spans than boys. This manuscript reports the liver size in Saudi children and adolescents. The data should help physicians in the interpretation of liver size determined by physical examination of children and adolescents. (author)

Role of social media in brand development in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Literature is ripe with the scholarly contributions on brand development from all aspects. The new marketing tools and techniques are introduced frequently. However, the impact social media has had on brand development is no match to traditional promotion in 4Ps. The information about Saudi Arabia is specially rare. This article based on a survey of 200 social media users on www.surveymonkey.com evaluates the role of social media in brand development in Saudi Arabia. The results from this Saudi example show that social media including Facebook and Twitter are among the most effective tool to develop a brand as compared to traditional promotional methods. It has also been found that these media are more successful in Saudi Arabia to develop the brand recall and image.

Symptomatic gallstones: A disease of young Saudi women  

Directory of Open Access Journals (Sweden)

Full Text Available This is a study performed to identify the risk factors for gallstones in Saudis, taking the patient population of King Khalid University Hospital as a sample. Only Saudis with symptomatic gallstones were studied, the parameters being age, sex, weight, body mass index, fertility, age at menarche and age at marriage. The results showed that sex, weight, body mass index and fertility all appeared to be important factors in the development of gallstones and that the condition affects more Saudi females and at a younger age than reported in the literature, probably due to overweight and factors related to reproductivity. We conclude that gallstones are common in Saudi women and affect them at a younger age than western women, weight and fertility appear to be important risk factors.

Full Text Available This study is an attempt to investigate the nature of obstacles and challenges encountered at Saudi universities while implementing a blended learning approach. A literature review of blended learning rationale and designs, and the status of web-based education in Saudi higher education are demonstrated. Three main challenges of applying blended learning in Saudi higher education are addressed. One major challenge to be considered in the implementation of blended learning in Saudi universities is the adaptation of this element in the traditional university culture. Finding the right design of blended learning is another challenge that is discussed in detail. Furthermore, the time issue is considered a crucial challenge facing blended learning faculty. Practical recommendations that would facilitate transition to a blended learning university environment are presented. It is hoped that this study will help to provide insight for the faculties and the decision-makers throughout higher education in Saudi Arabia. Although this investigation is specifically related to the implementation of blended learning in the universities of Saudi Arabia, we are confident that the assumptions and recommendations contained herein will be of great value to other populations facing similar challenges.

The pharmacoeconomic picture in Saudi Arabia.  

Science.gov (United States)

Saudi Arabia is the largest country in the region and it is the largest oil producing country in the world. It is one of the few countries in the world which was not affected significantly by the global economic crisis. Health care spending is led mainly by governmental expenditure. Private sector share of the health care services is supported by the government and increasing. The demands for pharmaceutical products, medical devices and health care services is fueled by the rapidly growing population and the wide spread of chronic diseases. Publications and expertise in the field of pharmacoeconomics is scarce within the country. There is an urgent need to establish a national center for pharmacoeconomics to lead the country efforts in controlling the cost of health care services. Such a center is needed to promote pharmacoeconomics research and train health care professionals in this field. PMID:24953076

Natural background radiation in Saudi Arabia  

International Nuclear Information System (INIS)

Natural background radiation measurements have been made at numerous locations throughout the world. Little work in this field has been done in developing countries. In this study, the external exposure rates due to natural background radiation sources have been measured for different Saudi Arabian cities. Thermoluminescence dosimeters, CaF2Dy(TLD-200), has been used for field measurements. Exposure to TLD's response correlations were obtained for each TLD using a 137Cs source. A correlation of TLD's response fading at a continuous radiation exposure environment was obtained and applied to correct field measurements. The measurements were taken every two months for a total of six intervals during the whole year. The average measurements of outdoor external exposure rates was found to vary between a minimum of 5.29 ?R h-1 in Dammam city and a maximum of 11.59 ?R h-1 in Al-Khamis city. (1 fig., 1 tab.)

Role of physics in Saudi engineering education  

Science.gov (United States)

In recent years some engineering schools in the Middle East have proposed reducing the amount of basic science courses in their curricula. A conference on engineering education in the Arabian Gulf countries held in Kuwait in 1980 suggested that the number of courses in physics and chemistry should be reduced from the present level (Jamjoom 1980). The arguments often put forward can be summarised as follows. First, engineering students are at present overburdened with too many basic science courses which puts a strain on the average student. This in turn leads to a high drop-out as is witnessed in many engineering colleges in this region. This drop-out, as high as 20% in some Saudi universities, is a cause of great concern among the university authorities. Secondly, it is argued that the number of credit hours allocated to departmental requirements is not sufficient to give a student enough breadth and depth of knowledge in his specialisation in particular engineering branches. Universities in Saudi Arabia follow the American credit-hour system in which courses are given certain credit hours, ranging from two to four, depending on the number of lectures per week as well as laboratory and tutorial requirements. Engineering students have to complete about 150 credit hours to graduate, which they normally do in four to five years. Out of these credit hours, about two-thirds are allocated to core courses (including physics) common to all branches of engineering. The remaining one-third are reserved for departmental specialisation. Since there is no possibility of increasing the overall credit hours necessary for graduation, it is suggested that the extra credit hours demanded for increasing the number of departmental courses should be obtained by correspondingly curtailing those for the basic sciences. When carefully scrutinised the arguments do not appear to be well founded. The reasons for high drop-out can be traced to more deep-rooted factors.

Essays on oil and business cycles in Saudi Arabia  

Science.gov (United States)

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. Second, the policymakers in Saudi Arabia should be more concerned with increasing productivity through adopting new technologies that increase economic prosperity. Therefore, the policymakers should continue diversifying economic resources and reduce their reliance on oil.

E-learning Accessibility for Saudi Women: A Literature Review  

Directory of Open Access Journals (Sweden)

Full Text Available Saudi government has made significant efforts and heavily invested in its e-learning innovation in order to offer students alternative opportunity to complete their higher education. However despite all the efforts being made, Saudi Arabia is still in the early stage of its e-learning development and faces many challenges especially for female’s students from their ability to take the benefit of such technology. Therefore, understanding the ability of Saudi women to access and use e-learning is more important than just make it available for them. In other words, the use of e-learning involves not just technical availability but the capability to benefit. In this regards, this paper will review the literature of e-learning accessibility for Saudi women by considering several different aspects including: general information about Saudi Arabia (e.g. country, society, education system, women’s education, higher education and e-learning, challenges of e-learning and women’s capacity to access e-learning freely.

Industrial Purchase among Saudi Managers: Does Country of Origin Matter?  

Directory of Open Access Journals (Sweden)

Full Text Available The country of origin or where a given product was designed or assembled has been found to be influential inseveral consumer studies. With the differentiation between the country of assembly and the country of design,the aim of this study was to examine the effect of country of origin (COO factors on the purchasing decisionsmade by purchasing Saudi managers in Saudi Arabia. The study identifes COO for two types of products,machine tools and component parts. Using convenience sampling method, a pilot-tested questionnaire surveywas sent out by email to 531 industrial managers responsible of the machine tools purchasing and componentsparts in Saudi Arabia with a response rate was 62 %, the author presents findings on purchasing managers’perceptions of industrial products sourced from a total of 18 countries. The findings of this study revealed thatCOO is a significant and major factor in Saudi managers’ purchase decisions with respect to industrial products.This study provides Saudi perspectives and insights on the ongoing debate regarding the role of country of originin our increasingly globalized world. The study is timely in view of the continued pace of globalization, withmost multinationals outsourcing their production in one or more countries. The results should be of interest to avariety of organizations involved in industrial products, including designers, manufacturers, buyers and otherstakeholders.

Gaped deficiency distribution and variants in Saudi Arabia: An overview  

International Nuclear Information System (INIS)

The first report of glucose-6-phosphate dehydrogenase (G6PD) deficiency in Saudi population of the Eastern Province paved the way for extensive investigations to determine the distribution and molecular pathogenesis of G6PD deficiency in Saudis in different parts of the country. During a national study lasting from 1980 to 1993, 24,407 Saudi in 31 different areas of Saudi Arabia screened for G6PD deficiency using spectrophoretic estimation of enzyme activity and electrophoretic separation of the phenotypes. The results in the males and females were separately analyzed and showed a statistically significant difference in the frequency in the male (0.0905) and female (0.041) population (P<0.05). The frequency in the male varied from 0 to 0.398 and in the female from 0 to 0.214. The phenotypes identified included G6PD-A, G6PD-Mediterranean and G6PD-Med-Like with G6PD-B as the normal phenotype in all areas. This study shows that G6PD deficiency is a frequently identified single-gene disorder in Saudi Arabia and G6PD-Mediterranean is the major variant producing the severe deficiency state in this population.

Pharmacy Education in Jordan, Saudi Arabia, and Kuwait  

Science.gov (United States)

The practice of pharmacy, as well as pharmacy education, varies significantly throughout the world. In Jordan, Kuwait, and Saudi Arabia, the profession of pharmacy appears to be on the ascendance. This is demonstrated by an increase in the number of pharmacy schools and the number of pharmacy graduates from pharmacy programs. One of the reasons pharmacy is on the ascendance in these countries is government commitment to fund and support competitive, well-run pharmacy programs. In this report we describe pharmacy education in 3 Middle East countries: Jordan, Kuwait, and Saudi Arabia. All 3 countries offer bachelor of pharmacy (BPharm) degrees. In addition, 2 universities in Jordan and 1 in Saudi Arabia offer PharmD degree programs. The teaching methods in all 3 countries combine traditional didactic lecturing and problem-based learning. Faculties of pharmacy in all 3 countries are well staffed and offer competitive remuneration. All 3 countries have a policy of providing scholarships to local students for postgraduate training abroad. The majority of students in Jordan and Kuwait are female, while the ratio of male to female students in Saudi Arabia is even. Students’ attitudes towards learning are generally positive in all 3 countries. In Saudi Arabia and Kuwait, most pharmacy graduates work in the public sector, while in Jordan, the majority work in the private sector. PMID:17136159

Novel mutations underlying argininosuccinic aciduria in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Argininosuccinic aciduria (ASAuria is an autosomal recessive disorder of the urea cycle relatively common in Saudi Arabia as a consequence of extensive consanguinity. It is the most common urea cycle disorder identified in the Saudi population, which therefore prioritizes the need to delineate the underlying molecular defects leading to disease. Findings We utilized Whole Genome Amplification (WGA, PCR and direct sequencing to identify mutations underlying ASAuria cases diagnosed by our institution. A missense mutation that accounts for 50% of Saudi ASAuria patients was recently reported by our laboratory. In this study we report a further six novel mutations (and one previously reported found in Saudi patients with ASAuria. The novel four missense, one nonsense and one splice-site mutation were confirmed by their absence in >300 chromosomes from the normal population. Pathogenicity of the novel splice-site mutation was also confirmed using reverse transcriptase-PCR analysis. Cross species amino acid conservation at the substituted residues described were observed in some but not all instances. Conclusions Together, the eight mutations described by our laboratory, encompass >90% of ASAuria patients in Saudi Arabia and add to about 45 other ASAuria mutations reported worldwide.

Science.gov (United States)

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.

Blood pressure standards for Saudi children and adolescents.  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objectives: Blood pressure levels may vary in children because of genetic, ethnic and socioeconomic factors. To date, there have been no large national studies in Saudi Arabia on blood pressure in children.Therefore, we sought to establish representative blood pressure reference centiles for Saudi Arabian children and adolescents. Subjects and Methods: We selected a sample of children and adolescents aged from birth to 18 years by multi-stage probability sampling of the Saudi population. The selected sample represented Saudi children from the whole country. Data were collected through a house-to-house survey of all selected households in all 13 regions in the country. Data were analyzed to study the distribution pattern of systolic (SBP and diastolic blood pressure (DBP and to develop reference values. The 90th percentile of SBP and DBP values for each age were compared with values from a Turkish and an American study. Results: A total of 16 226 Saudi children and adolescents from birth to 18 years were studied. Blood pressure rose steadily with age in both boys and girls. The average annual increase in SBP was 1.66 mm Hg for boys and 1.44 mm Hg for girls. The average annual increase in DBP was 0.83 mm Hg for boys and 0.77 mm Hg for girls. DBP rose sharply in boys at the age of 18 years. Values for the 90th percentile of both SBP and DBP varied in Saudi children from their Turkish and American counterparts for all age groups. Conclusion: Blood pressure values in this study differed from those from other studies in developing coun--tries and in the United States, indicating that comparison across studies is difficult and from that every popula--tion should use their own normal standards to define measured blood pressure levels in children.

Information Privacy Status in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Privacy is one of the most fundamental rights that must be preserved for individuals because it is integral to their integrity, self-respect, and safety. However, it is also a vague concept with a number of controversial issues that need to be addressed from ethical, jurisdictional, and sociological perspectives. The perceptions of both organizations and individuals have undergone noticeable changes since the introduction of communication and processing technologies. Furthermore, with the dominance of the Internet and social networks in business and personal lives, information privacy appears to be a myth as massive volumes of personal information and data are stored in the Cloud and back end systems of organizations. Such systems have created serious legal, ethical, and technological challenges related to information collection, processing, and dissemination. This paper presents the findings of the first phase of a countrywide research project that aims to provide a comprehensive assessment of information privacy practices in the public, health, banking, and private sectors. The results presented in this paper are based on a survey and structured interviews with key stakeholders in multiple organizations in the Kingdom of Saudi Arabia to measure organizational compliance and personal perceptions of information privacy.

Full Text Available This study is a comparison of gamma ray linear attenuation coefficient of two typs of shielding materials made of Saudi white and red sand. Each shield was consisted of one part of cement two parts of sand in addi-tion to water. Different thicknesses were tested. The concentrations of all elements in each shield material were determined by Inductively Coupled Plasma Mass Spectrometer (ICP-MS. The results obtained from the ICP-MS were used in MCNP4B (Monte Carlo N-Particle Transport Computer Code System [1] to calculate the attenuation coefficient. The theoretical (MCNP4B and the experimental calculations were found to be in a good agreement. In the casw of the largest thickness used, 28cm, the gamma ray intensity passing through the white sand shield was approximately half of the intensity obtained through the red sand shield. The average linear attenuation coefficients were found to be 0.17cm-1 and 0.15cm-1 for white and red sand shields respectively. The study shows that white sand is better for attenuating gamma ray compared to the red sand.

Oral lesions in Saudi renal transplant patients  

Directory of Open Access Journals (Sweden)

Full Text Available Renal transplantation has evolved as the best treatment option for patients with end-stage renal disease. Different oral problems arise in these patients, either as a direct consequence of drug-induced immunosuppression or pharmacokinetics. To determine the prevalence of intra-oral lesions in a group of medically stable Saudi renal transplant patients (RTP and to identify possible risk factors, in comparison with age and sex-matched healthy control subjects (HCS, we studied 58 RTP and 52 HCS. All subjects had a thorough oral examination and oral lesions were diagnosed according to the clinically accepted criteria. Gingival overgrowth (GO, erythematous candidiasis (EC and hairy leukoplakia (HL were diagnosed in RTP with prevalence of 74.1%, 15.5%, and 8.6%, respectively. The severity of the gingival overgrowth significantly correlated with the use of cyclosporine and nifedipine combination therapy, serum cyclosporine, and serum creatinine level. In conclusions, the finding of our study strongly propose that RTP should undergo routine and regular comprehensive oral examination, and any suspicious lesion must be investigate and treated.

Public awareness of blood donation in Central Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Mostafa A Abolfotouh,1,2 Mohammed H Al-Assiri,1 Manar Al-Omani,2 Alwaleed Al Johar,3 Abdulaziz Al Hakbani,3 Ahmed S Alaskar1,2 1King Abdullah International Medical Research Center, 2King Saud bin-Abdulaziz University for Health Sciences, 3College of Medicine, King Saud University, Riyadh, Saudi Arabia Introduction: In Saudi Arabia, voluntary donors are the only source of blood donation. The aim of this study was to assess the level of public knowledge and attitude toward blood donation in Saudi Arabia. Methods: Using a previously validated questionnaire that comprises 38 questions to assess the levels of knowledge, attitudes, and motivations towards blood donation, 469 Saudi adults who attended different shopping malls in Riyadh, Saudi Arabia were surveyed. Multiple regression analyses were used to identify the significant predictors of blood donation, with the significance set at P<0.05. Results: Approximately half of all subjects (53.3% reported that they had previously donated blood, 39% of whom had donated more than once. The knowledge percentage mean score was 58.07%, denoting a poor level of knowledge, with only 11.9% reporting a good level of knowledge. The attitude percentage mean score towards donation was 75.45%, reflecting a neutral attitude towards donating blood, with 31.6% reporting a positive attitude. Donation was significantly more prevalent among males than females (66% versus 13.3%; P<0.001. After adjustment for confounders, a higher knowledge score (t=2.59; P=0.01, a higher attitude score (t=3.26; P=0.001, and male sex (t=10.45; P<0.001 were significant predictors of blood donation. An inability to reach the blood donation centers and a fear of anemia were the main reasons for females not donating blood (49.9% and 35.7%, respectively, whereas a lack of time was the main reason for males (59.5%. Conclusion: Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor knowledge, and unfavorable attitude to donation. Educational programs are necessary to increase the level of knowledge and improve the attitude of the Saudi public toward blood donation. Providing mobile blood collection units nearer to individuals' places of work to reduce their time costs of donating is a necessity.

Purine nucleoside phosphorylase deficiency in two unrelated Saudi patients  

Directory of Open Access Journals (Sweden)

Full Text Available Purine nucleoside phosphorylase (PNP deficiency is a rare autosomal recessive metabolic disorder that results in combined immunodeficiency, neurologic dysfunction and autoimmunity. PNP deficiency has never been reported from Saudi Arabia or in patients with an Arabic ethnic background. We report on two Saudi girls with PNP deficiency. Both showed severe lymphopenia and neurological involvement. Sequencing of the PNP gene of one girl revealed a novel missense mutation Pro146>Leu in exon 4 due to a change in the codon from CCT>CTT. Expression of PNP (146L cDNA in E coli indicated that the mutation greatly reduced, but did not completely eliminate PNP activity.

Skin lipids from Saudi Arabian birds.  

Science.gov (United States)

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

Slow, slow, quick, quick, slow: Saudi Arabia's 'Gas Initiative'  

International Nuclear Information System (INIS)

This article sets out to analyse the Saudi gas initiative in the context of the decision-making process in Saudi Arabia between 1998 and 2002. It describes the overall context in which the initiative was made. It focuses on the personalities and institutions that were important in its birth and its evolution. The article argues that a mixture of personalities (especially that of Crown Prince Abdullah and foreign minister Saud al-Faisal) and institutions (especially a clutch of new bodies formed in 1999 and 2000) were pivotal in the emergence of the initiative. It also looks at the obstacles that were placed in the way of the initiative, arguing that Saudi Aramco and the minister of oil, Ali Naimi, were key blocking players. Over time, the Saudi gas initiative has come to be seen as a benchmark of the wider cause of economic liberalization in the Kingdom. The lack of progress in the initiative since the initial indicative contract awards in June 2001 has reflected the lack of movement in the general reformist strategy

Saudi Aramco experience towards establishing Pipelines Integrity Management Systems (PIMS)  

Energy Technology Data Exchange (ETDEWEB)

Saudi Aramco pipelines network transports hydrocarbons to export terminals, processing plants and domestic users. This network faced several safety and operational-related challenges that require having a more effective Pipelines Integrity Management System (PIMS). Therefore Saudi Aramco decided to develop its PIMS on the basis of geographical information system (GIS) support through different phases, i.e., establishing the integrity management framework, risk calculation approach, conducting a gap analysis toward the envisioned PIMS, establishing the required scope of work, screening the PIMS applications market, and selecting suitable tools that satisfy expected deliverables, and implement PIMS applications. Saudi Aramco expects great benefits from implementing PIMS, e.g., enhancing safety, enhancing pipeline network robustness, optimizing inspection and maintenance expenditures, and facilitating pipeline management and the decision-making process. Saudi Aramco's new experience in adopting PIMS includes many challenges and lessons-learned associated with all of the PIMS development phases. These challenges include performing the gap analysis, conducting QA/QC sensitivity analysis for the acquired data, establishing the scope of work, selecting the appropriate applications and implementing PIMS.

Prevalence of overweight and obesity in Saudi children and adolescents  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objective : There is limited information on overweight and obesity in Saudi children and adolescents. The objective of this study was to establish the national prevalence of overweight and obesity in Saudi children and adolescents. Methods : The 2005 Saudi reference data set was used to calculate the body mass index (BMI for children aged 5 to 18 years. Using the 2007 WHO reference, the prevalence of overweight, obesity and severe obesity were defined as the proportion of children with a BMI standard deviation score more than +1, +2 and +3, respectively. The 2000 CDC reference was also used for comparison. Results : There were 19 317 healthy children and adolescents from 5 to 18 years of age, 50.8% of whom were boys. The overall prevalence of overweight, obesity and severe obesity in all age groups was 23.1%, 9.3% and 2%, respectively. A significantly lower prevalence of overweight (23.8 vs 20.4; P < .001 and obesity (9.5 vs 5.7; P < .001 was found when the CDC reference was used. Conclusions : This report establishes baseline national prevalence rates for overweight, obesity and severe obesity in Saudi children and adolescents, indicating intermediate levels between developing and industrialized countries. Measures should be implemented to prevent further increases in the numbers of overweight school-age children and adolescents and the associated health hazards.

Vitamin D levels in healthy men in eastern Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Studies in 1980s and 1990s indicated that vitamin D levels in the ethnic Saudi Arabian population were low but no studies since that time have evaluated vitamin D levels among healthy young or middle-aged Saudi men. Thus, we assessed the serum level of 25-hydroxyvitamin D (25OHD among healthy Saudi Arabian men living in the Eastern Province. Subjects and Methods : One hundred males aged 25-35 years (the age range of peak bone mass and 100 males aged 50 years or older were randomly selected and evaluated clinically, including measurement of serum calcium, parathyroid hormone (PTH and serum 25OHD levels. Vitamin D deficiency was defined as a serum level of 25OHD of ?20 ng/mL and insufficiency as a serum level between> 20 ng/mL and < 30 ng/mL and normal ?30 ng/mL. Results: The mean (SD age of subjects in the younger age group was 28.2 (4.5 years. Twenty-eight (28% had low 25OHD levels; 10 (10% subjects were vitamin D deficient with a mean level of 16.6 (3.4 ng/mL and 18 (18% were vitamin D insufficient with a mean level of 25.4 (2.7 ng/mL. In the older age group, the mean age was 59.4 (15.6 years and 37 (37% had low 25OHD; 12 (12% subjects were deficient with a mean 25OHD level of 16.7 (3.4 ng/mL and 25 (25% were insufficient with a mean 25OHD level of 25.3 (3.3 ng/mL. Conclusions: The prevalence of vitamin D deficiency among healthy Saudi men is between 28% to 37%. Vitamin D deficiency among young and middle age Saudi Arabian males could lead to serious health consequences if the issue is not urgently addressed.

Epidemiology of chronic kidney disease in the Kingdom of Saudi Arabia (SEEK-Saudi investigators) - A pilot study  

International Nuclear Information System (INIS)

There are no available data about the prevalence of chronic kidney disease (CKD) and its risk factors in the general population of the kingdom of Saudi Arabia. To estimate the prevalence of CKD and its associated risk factors in the Saudi population, we conducted a pilot community-based screening program in commercial centers in Riyadh, Saudi Arabia. Candidates were interviewed and blood and urine samples were collected. Participants were categorized to their CKD stage according to their estimated Modification of Diet in Renal Disease (MDRD3)-based, the new Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation and the presence of albuminuria. The sample comprised 491 (49.9% were males) adult Saudi nationals. The mean age was 37.4 ± 11.3 years. The overall prevalence of CKD was 5.7% and 5.3% using the MDRD-3 and CKD-EPI glomerular filtration equations, respectively. Gender, age, smoking status, body mass index, hypertension and diabetes mellitus were not significant predictors of CKD in our cohort. However, CKD was significantly higher in the older age groups, higher serum glucose, waist/hip ratio and blood pressure. Only 7.1% of the CKD patients were aware of their CKD status, while 32.1% were told that they had protein or blood in their urine and 10.7% had known kidney stones in the past. We conclude that prevalence of CKD in the young Saudi population is around 5.7%. Our pilot study demonstrated the feasibility of screening for CKD. Screening of high-risk individuals is likely to be the most cost-effective strategy to detect CKD patients (Author).

A sample of 239 (127 males and 112 females healthy Saudi adults was recruited. Vitamin B6 status was evaluated by dietary intake and biochemical measurements. Results of dietary intake measurements showed that means of vitamin B6 intake and intake of vitamin B6 to protein ratio for males and females were 1.97±0.58 mg/day, 0.021±0.003 and 1.89±0.61 mg/day, 0.020±0.04, respectively. Results of biochemical measurements showed that means of plasma pyridoxal phosphate (PLP concentration and average urinary 4-Pyridoxic Acid (4-PA excretion for males and females were 29.6±9.6 nmol L-1 and 7.0±2.4 ?mol day-1 and 31.7±10.4 nmol L-1 and 6.8±2.5 ?mol day-1, respectively. The study also investigated and discussed other health indicators that are related to vitamin B6 status including Body Mass Index (BMI, plasma albumin concentration and alkaline phosphatase activity. Results of dietary intakes and biochemical measurements indicated an adequate status of vitamin B6. There were no significant differences between males and females in any of the previous measurements. This study indicated an adequate status of vitamin B6 among healthy adult Saudis in Al-Qassim region, however due to the numerous functions and the importance of the vitamin, the study suggested a further evaluation in various groups of the Saudi population in other regions of the country.

Subacute thyroiditis in Western Saudi Arabia  

International Nuclear Information System (INIS)

The aim of this study is to assess the clinical presentation of 23 patients with subacute thyroiditis (SAT) and the diagnostic value of radionuclear scan. This is a cohort study, which consists of 23 patients with a suspected diagnosis of subacute thyroiditis. The study was carried out in the Endocrinology Clinic, King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia between July 2002 and July 2004. Medical charts including age, gender, clinical presentation, systemic symptoms and clinical examination of the thyroid gland were reviewed. Laboratory data included white blood count and its differential count, erythrocyte sedimentation rate (ESR), thyroid function test and thyroid antibodies. The radionuclear scan results were also noted. The mode of therapy provided to patients and the outcome of the treatment during a follow up period of 2 years was reported. Twenty-three adult patients with subacute thyroiditis (15 females and 8 males with a female to male ratio of 1.9:1) were reviewed over a 2-year period. The mean age was 35.8+9.2 years. Eighteen patients (78%) had an upper respiratory tract infection at the initial clinical presentation. Twenty patients (87%) visited an Ear, Nose and Throat specialist for sore throat and abnormal sensation in the throat at least 2 weeks before presentation to the endocrinologist. Two patients were admitted to a medical unit with a diagnosis of fever of unknown origin for 4 weeks. All patients had an elevated free thyrks. All patients had an elevated free thyroxine (35.7+19.8 pmol/L) and suppressed thyroid-stimulating hormone (TSH) (0.043+0.065IU). The radionuclear scan showed either no uptake at all in 12 patients or minimal uptake in 11 patients (0.32+0.55%). Eight patients (35%) received prednisolone therapy alone with an average dose of 30-40 mg daily for 7-8 days; 7 patients (30%) were treated with non-steroidal anti-inflammatory drugs (NSAIDs) only. Eight (35%) patients were treated with both NSAIDs and corticosteroids. Hypothyroidism, with elevated TSH, was observed in 6 (26%) of our patients with positive thyroid antibodies during the first 6 months of follow up. There were no reported cases of recurrent or permanent hypothyroidism in our cohort study. Subacute thyroiditis is an uncommon disease that should be considered in the differential diagnosis of acute anterior neck pain, sore throat and fever especially in patients who do not respond to treatment. In the clinical setting, radioiodine uptake can help exclude other diseases, confirm the diagnosis and expedite the initiation of appropriate therapy to relieve symptoms. (author)

A Study of the Effect of Macroeconomic Variables on Stock Market: Saudi Perspective  

Directory of Open Access Journals (Sweden)

Full Text Available As we know investment in the Saudi stock market (TASI is gaining popularity particularly since 2001 (Report of Aljazira Capital – 2010, it is important to know the impact of different macro-economic variables on the returns of the Saudi stock market. In this regard along with an extensive literature review we also referred specific recent few important studies which considered the Saudi stock return as a dependent variable and other economic factors as the independent variables [Kalyanaraman and Al-Tuwajri (2014, Arouri and Rault (2010 and Onour (2008]. This paper examines the three important factors influencing the returns in the Saudi Stock Exchange (TASI based on the macroeconomic variables of Saudi Economy. The dependent variable taken here is the Saudi index that is TADAWUL All Stock Index (TASI and the three independent variables considered for our study here are the Oil WTI, Saudi Exports and the PE Ratio. Correlation analysis revealed that Saudi Exports and the PE Ratio were found to be highly correlated with TASI at 1% level of significance whereas Oil WTI and TASI are significantly correlated at 5% level. Step-wise regression analysis of the data revealed that the multiple regression models is significant at 1% level and the variable PE Ratio was the most important determinant of TASI followed by Oil WTI and Saudi Exports. Further the three independent variables explain about 93% of variation in the TASI Last Price.

Physical activity, fitness and fatness among Saudi children and adolescents: implications for cardiovascular health.  

Directory of Open Access Journals (Sweden)

During recent years, the Kingdom of Saudi Arabia has witnessed a tremendous development at an astounding rate. The standard of living rises and mechanization has been apparent in all aspects of people's life. As industrialization and modernization progress, a number of changes in physical activity and eating habits are likely to occur. Indeed, physical inactivity and sedentary living with associated low level of physical fitness are increasingly becoming prevalent in the Saudi society. These lifestyle changes undoubtedly carry unfavorable consequences on health outcomes of the Saudi population. This paper reviews the status of physical activity among Saudi children and adolescents and discusses its implications to cardiovascular health and fitness. From the available evidences, it appears that most Saudi children and adolescents do not meet the minimal weekly requirement of moderate to vigorous physical activity necessary for effectively functioning cardiorespiratory system. Furthermore, active Saudi boys tend to have favorable levels of serum triglycerides and high density lipoproteins-cholesterol compared with inactive boys. Sixteen percent of Saudi schoolboys are considered obese (fat content is above 25% of body mass. Body fat percent of Saudi boys seems to have increased over the past decade. Body fatness correlated significantly with several coronary artery disease risk factors. Based on the available evidences, promotion of physical activity among Saudi children and adolescents appears warranted and national policy encouraging active living is also needed.

Public awareness of blood donation in Central Saudi Arabia  

Science.gov (United States)

Introduction In Saudi Arabia, voluntary donors are the only source of blood donation. The aim of this study was to assess the level of public knowledge and attitude toward blood donation in Saudi Arabia. Methods Using a previously validated questionnaire that comprises 38 questions to assess the levels of knowledge, attitudes, and motivations towards blood donation, 469 Saudi adults who attended different shopping malls in Riyadh, Saudi Arabia were surveyed. Multiple regression analyses were used to identify the significant predictors of blood donation, with the significance set at P<0.05. Results Approximately half of all subjects (53.3%) reported that they had previously donated blood, 39% of whom had donated more than once. The knowledge percentage mean score was 58.07%, denoting a poor level of knowledge, with only 11.9% reporting a good level of knowledge. The attitude percentage mean score towards donation was 75.45%, reflecting a neutral attitude towards donating blood, with 31.6% reporting a positive attitude. Donation was significantly more prevalent among males than females (66% versus 13.3%; P<0.001). After adjustment for confounders, a higher knowledge score (t=2.59; P=0.01), a higher attitude score (t=3.26; P=0.001), and male sex (t=10.45; P<0.001) were significant predictors of blood donation. An inability to reach the blood donation centers and a fear of anemia were the main reasons for females not donating blood (49.9% and 35.7%, respectively), whereas a lack of time was the main reason for males (59.5%). Conclusion Prevalence of blood donation was less than satisfactory among the Saudi public, probably due to misconceptions, poor knowledge, and unfavorable attitude to donation. Educational programs are necessary to increase the level of knowledge and improve the attitude of the Saudi public toward blood donation. Providing mobile blood collection units nearer to individuals’ places of work to reduce their time costs of donating is a necessity. PMID:25152628

The Teacher of English: Pedagogic Relevance in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available The present paper attempts to explore the characteristics of an effective teacher of English. Some related factors such as qualification, attributes, roles, and professional ethics have also been dealt with. In Saudi Arabia, the teacher of English plays the most important role in the process of teaching/learning. There are so many factors such as L1 interference, parental attitude, home environment, schooling etc that are usually influential in the case of educational setting in general and English classes in particular. It is believed that if the teacher of English has undergone a pre-service teacher training it is better for the learners of Saudi Arabia. In the other case, those who have not attended pre-service teacher training, they should go for in-service professional development programs in order to equip them further for innovative teaching and educational output.

A Web-Based Cancer Atlas of Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available There is a distinct lack of online atlases to visualize and explore cancer incidence in Middle Eastern countries despite the clear benefit that such tools can deliver. This paper describes the development and implementation of a cancer Atlas of Saudi Arabia, which is a web-based client-server application with built-in analysis functions for analyzing patterns of cancer incidence. Built using ESRI’s ArcGIS Server API and ASP.NET, the atlas contains 45,532 incidences of cancer for the period from 1998 to 2004, which were provided by the Saudi Arabian National Cancer Registry. This tool is aimed at health care practitioners and researchers, who can use this tool for exploring cancer distribution and investigating trends, and as a decision support tool for service allocation. The tool allows users to map cancer incidence and undertake analyses at four spatial scales from city to national level.

Dermatological manifestations of hepatitis C virus infection in Saudi Arabia.  

Science.gov (United States)

The Saudi Ministry of Health data indicates that almost 32% of viral hepatitis cases were caused by hepatitis C virus (HCV). It has been widely reported that chronic HCV infection is associated with and may trigger or exacerbate many skin manifestations in 20-40% of patients visiting dermatologists. The most commonly encountered dermatological manifestations of HCV infection globally include mixed cryoglobulinemia, porphyria cutanea tarda, cutaneous and/or oral lichen planus, urticaria, pruritus, thrombocytopenic purpura, and psoriasis. The current article indicates that HCV infection is increasing in Saudi Arabia and approximately 12% of the reported dermatological manifestations are caused by HCV infection. We recommend the urgent need for large-scale, case-control studies to understand the impact of HCV infection in patients with skin disease. PMID:24888650

Class III malocclusion: a cephalometric study of Saudi Arabians.  

Science.gov (United States)

The records of 500 consecutive Saudi Arabian patients referred for orthodontic treatment were examined clinically and cephalometrically for Class III malocclusion. A control group was drawn at random from the same sample. The incidence of Class III was 9.4 per cent, with mandibular prognathism being the commonest presentation of the malocclusion. The upper and lower incisors exhibited a marked degree of dentoalveolar compensation, on dental bases having mean values of SNA--78.77 degrees and SNB--81.17 degrees. The maxillary length was reduced, as were the saddle and maxillary-mandibular plane angles. The gonial angle (ArGoMe), anterior and posterior facial heights, and mandibular lengths (ArGo, ArPo) were all significantly larger than the control group. The cephalometric values of the control group showed the increased tendency to bimaxillary protrusion in the Saudi Arabian sample. PMID:2765469

Risk Factors for Obesity among Saudi Female College Students  

Directory of Open Access Journals (Sweden)

Full Text Available Obesity is alarmingly raising in young people necessitating foridentification of precise causes specific for populations. The aim of the present study is to determine independent contribution of parental socioeconomic variables and self-life style factors to obesity in Saudi female college students. We performed a cross-sectional study using a random selection of 300 women aged 18–26 years recruited from the female campus of University of Hail, Saudi Arabia and collected self-reported information to meet study objectives. Around 32 % of females were either overweight or obese and the study subjects with a family history of maternal obesity and habit of limited snacking had higher odds for obesity. No associations were found between obesity and parental income and education status; and skipping breakfast and physical activity behaviours of the subjects. Maternal obesity could be a considerable risk factor for obesity in female subjects.

Directory of Open Access Journals (Sweden)

Full Text Available Background: Little attention has been paid to the problem of male os-teopororsis in Saudi Arabia. In this prospective study we assessed the prevalence of male osteoporosis among Saudi Arabs. Subjects and Methods: We studied Saudi Arabian males > 50 years of age attending outpatient clinics at King Fahd Hospital of the University, Al-Khobar, between 1 May 2005 and 30 January 2006. We determined body mass index (BMI and tests were done to rule out secondary os-teoporosis. All subjects had a bone mineral density (BMD measurement of the hip area and the lumbar spine using dual energy X-ray absorpti-ometry (DEXA. A T-score of -2.5 SD that of young, healthy adults was taken as osteoporotic and scores between -1 to -2.5 SD were taken as osteopenic. Results: One hundred fifteen patients (mean age, 61.8±0.75 years; range, 50 to 76 years had a mean BMI of 24.7±0.35 (range, 18.5 to 31. Based on hip scans, the prevalence of osteoporosis was 24.3%. Sixty-four percent were osteopenic. Based on scans of the lumbar spine, the prevalence of osteoporosis was 37.4% and 33.9% were osteopenic. Spinal osteoporosis was more common than hip osteoporosis. Conclusions: Our study indicates that the prevalence of osteoporosis among Saudi Arabian males is higher than among Western males. More studies are needed to determine the national prevalence of male osteo-porosis. It is recommended that serious measures to be undertaken to prevent male osteoporosis to stop any future epidemic of catastrophic osteoporosis-related fractures.

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.

Epidemiology of sickle cell disease in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Sickle cell disease (SCD is an autosomal recessive disorder characterized by production of abnormal hemoglobin S and is associated with high morbidity and mortality. Information about the prevalence of SCD in Saudi Arabia is patchy and probably underestimated, but studies have reported that SCD is a relatively common genetic disorder in this part of the world. The prevalence of SCD in Saudi Arabia varies significantly in different parts of the country, with the highest prevalence is in the Eastern province, followed by the southwestern provinces. The reported prevalence for sickle-cell trait ranges from 2% to 27%, and up to 2.6% will have SCD in some areas. Clinical and hematological variability exists in SCD in Saudi Arabia with two major phenotypes: a mild phenotype and a severe phenotype. Further studies on the prevalence, molecular and clinical epidemiology of SCD may help predict disease severity and risk stratification of patients to determine whether to receive early intensive care or continued symptomatic care.

Obesity and Associated Factors — Kingdom of Saudi Arabia, 2013  

Science.gov (United States)

Introduction Data on obesity from the Kingdom of Saudi Arabia (KSA) are nonexistent, making it impossible to determine whether the efforts of the Saudi Ministry of Health are having an effect on obesity trends. To determine obesity prevalence and associated factors in the KSA, we conducted a national survey on chronic diseases and their risk factors. Methods We interviewed 10,735 Saudis aged 15 years or older (51.1% women) through a multistage survey. Data on sociodemographic characteristics, health-related habits and behaviors, diet, physical activity, chronic diseases, access to and use of health care, and anthropometric measurements were collected through computer-assisted personal interviews. We first compared sociodemographic factors and body mass index between men and women. Next, we conducted a sex-specific analysis for obesity and its associated factors using backward elimination multivariate logistic regression models. We used SAS 9.3 for the statistical analyses and to account for the complex sampling design. Results Of the 10,735 participants evaluated, 28.7% were obese (body mass index ?30 kg/m2). Prevalence of obesity was higher among women (33.5% vs 24.1%). Among men, obesity was associated with marital status, diet, physical activity, diagnoses of diabetes and hypercholesterolemia, and hypertension. Among women, obesity was associated with marital status, education, history of chronic conditions, and hypertension. Conclusion Obesity remains strongly associated with diabetes, hypercholesterolemia, and hypertension in the KSA, although the epidemic’s characteristics differ between men and women. PMID:25299980

Physical inactivity among Egyptian and Saudi medical students  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: Medical students, the future doctors, were presumed to be knowledgeable about physical activity and would have future influence on their patients. This study aims to describe the pattern of physical activity, predictors of physical inactivity and perceived barriers to and benefits of physical activity among a sample of Egyptian and Saudi medical students. Methods: A cross-sectional comparative study was carried out on 319 Egyptian and 297 Saudi medical students. The long form of the international physical activity questionnaire (IPAQ was used to measure physical activity. Data was analyzed according to the guidelines for data processing and analysis of the IPAQ. Perceived barriers to and potential benefits of physical activity were reported. Results: Physical inactivity was significantly higher among Saudi than Egyptian medical students (41.1% versus 15.4%, respectively. Logistic regression analysis revealed that the independent predictors of physical inactivity were non-membership in sports clubs (OR =4.6 and use of private cars for transportation (OR=3.9. The most frequent barriers to physical activity are time limitation due to busy study schedule and lack of accessible and suitable sporting places. More than 70% of students perceived that physical activity promotes and maintains health. Conclusions: Because time and access are key barriers to medical student exercise, we believe that provision of free playgrounds in the college to practice sports during free times will promote physical activity in students.

Prevalence of ?-1-Antitrypsin Gene Mutations in Saudi Arabia  

Science.gov (United States)

Background/Aim: ?-1 antitrypsin (AAT) deficiency results from mutations of the protease inhibitor (PI). The AAT gene is mapped on chromosome 14 and has been associated with chronic liver disease and chronic obstructive pulmonary disease (COPD). Objective: To determine the frequency of AAT mutations on S and Z carrier alleles in healthy Saudi individuals from Qassim Province in Saudi Arabia. Patients and Methods: A total of 158 healthy, unrelated participants from Qassim Province were recruited. They were genotyped for the two AAT-deficiency alleles, PI*S and PI*Z, using polymerase chain reaction, with primers designed throughout to mediate site-directed mutagenesis. Results: Of the 158 subjects, 11.39% were carriers for the S mutation (i.e., had the MS genotype), whereas 2.53% were carriers for the Z mutation (i.e., had the MZ genotype). The SZ genotype was present in 3.8% of subjects, while the homozygous genotype SS was present in 1.9% of subjects. No subjects showed the ZZ mutant genotype. Accordingly, frequency of the mutant S and Z alleles of AAT gene was 9.49% and 3.19%, respectively. Conclusion: The results obtained showed a high prevalence of the AAT deficiency allele in the Saudi population. This probably warrants adoption of a screening program for at-risk individuals, so that they might initiate adequate prophylactic measures. PMID:21727732

Human sensitization to Prosopis Juliflora antigen in Saudi Arabia  

International Nuclear Information System (INIS)

Allergenicity Prosopis juliflora pollen antigen has been reported fromonly a few countries, including the US, South Africa, India and Kuwait. Insome parts of Saudi Arabia, species of Prosopis have been introduced by themillions as roadside ornamentation. There appear to be four flowering seasonsduring which pollen grains float in all directions. However, the role ofProsopis pollen as the sensitizing and/or rhinitis in the Kingdom has neverbeen evaluated. A total of 473 allergic patients suffering from the bronchialasthma in four different geographical regions (Abha, Qassim, Hofuf, Gizan),and attending allergy clinics and chest disease centers of university andMinistry of Health hospitals in the region were tested for immediatehypersensitivity reaction to Prosopis Juliflora allergens. Airborne pollengrains at one center were also studied for one full year, using volumetricsampling techniques. A total of 76.1% patients in Qassim, 37.5% in Gizan, 29%in Abha and 11% in Hofuf reacted positively to Prosopis antigen. Multiplesensitivities to other pollen antigens were detected in all patients. Thelevel of airborne Prosopis pollen detected in Gizan exceeded 90 grains m ofair. In view of documented evidence of Prosopis pollen as a sensitizingfactor in Saudi Arabia has been confirmed. However the cause of elicitationof symptoms in many multiple sensitive patients, together with the questionof cross-reactivities, needs thorough and detailed investigation. In vitroconfirmation ofled investigation. In vitroconfirmation of all positive results is also required to incriminate Prosopisas one of the major allergens in parts of Saudi Arabia. (author)

Crude oil price fluctuations and Saudi Arabia's behaviour  

International Nuclear Information System (INIS)

This study attempts to explain why crude oil prices fluctuate, the main cause being the quota regime, which characterises the OPEC agreements. Given that the Saudi oil supply is inelastic in the short term, a shock in the oil market is accommodated by an immediate price change. By contrast, a dominant firm behaviour in the long term causes an output change, which is accompanied by a smaller price change. This explains why oil prices overshoot. The results of a general equilibrium model applied to Saudi Arabia support this analysis. They also indicate that Saudi Arabia does not have any incentive for altering the crude oil market equilibrium with either positive or negative supply shocks, as its welfare declines; and that it has an incentive (disincentive) for intervening if a negative (positive) demand shock hits the crude oil market. A second set of simulations is designed to understand what kind of OECD policy might help to bring down prices. A tax cut would worsen the situation, whereas policies that can increase the price elasticity of demand seem to be very effective. (Author)

Directory of Open Access Journals (Sweden)

Full Text Available Presently many dairy products are being used in Saudi Arabia. Monitoring and isolation of bacterial activity is of highly significance to sustainable health problems and issues. The objective of the study was to isolate bacteriocin-producing Lactic Acid Bacteria (LAB from some traditional Saudi food. A total of 50 samples from dairy products, commonly consumed in Saudi Arabia, were screened for presence of natural LAB. The Cell-free Supernatants (CFS of two LAB isolates exhibited antibacterial activities (inhibition zones >10 mm against food-borne pathogens (Lactococcus monocytogenes ATCC 7644, Staphylococcus aureus ATCC 29213 and Salmonella enteritidis ATCC13076. The growth inhibitory substances of CFS were sensitive to proteases (Protenase K and Pepsin indicating the proteinaceous nature of inhibitors (bacteriocins produced by the two LAB isolates. Their bacteriocins retained activity after thermal treatments (63°C for 30 min, 100°C for 10 min or 121°C for 15 min or at pH ranging from 4.0 to less than 6.5. The two LAB isolates were phenotypically identified as Lactococcus lactis subsp. lactis (camel’s milk and Lactobacillus paracasei (goat’s milk. The isolated LAB (Lactococcus lactis subsp. lactis and Lactobacillus paracasei can be used as food preservatives and probiotics since they inhibited well-known food-borne pathogens such as L. monocytogenes and survived acidic conditions (pH 2.5 similar to those of the stomach.

New Seismicity Map for Central Part of Saudi Arabia  

Science.gov (United States)

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.

Exercise capacity of Saudi with symptoms suggestive of cardiovascular disease in a military hospital in Western Saudi Arabia  

International Nuclear Information System (INIS)

Objective was to analyze the results of exercise tolerance test ETT of Saudi women and assess their exercise capacity. A hospital based retrospective cohort analysis was carried out on all Saudi women referred to the Cardiology Department for ETT from February 2005 to June 2007. They underwent symptom limited treadmill test according to the standard Bruce protocol with exercise electrocardiogram monitoring. One hundred and seventy-six women were included in the study. Fifty-one 31.9% patients did not achieve target heart rate. The mean age +/- SD was 48.3+-9.3 years. There was no association of age, diabetes mellitus, hypertension, positive family history of ischemic heart disease IHD and hyperlipidemia to achieve target heart rate p>0.05. Exercise time was influenced by diabetes mellitus p=0.054 and hyperlipidemia p=0.044. The mean exercise time +/- SD was 5.15+/-2.63 minutes and the mean exercise capacity +/-SD was 6.29+/-2.52 metabolic equivalent. Sensitivity was 36.4%, 95% CI 29.3-44.6, specificity 92.3%, 95% CI 80.5-96.8, positive predictive value 26.7%, 95% CI 21.3-31.4, negative predictive value 95.4%, 95% CI 90.9-98.3, likelihood ratio for positive result was 4.7, 95%CI 3.1-6.2 and likelihood ratio for negative result was 0.69, 95% CI 0.48-0.81. Exercise capacity of Saudi women is less compared to similar studies in women from other regions. Exercise tolerance test can be used to rule out presence of IHD in Saudi women, but value of a positive test is less likely to predict the presence of IHD. (author)

Tertiary care availability and adolescent pregnancy characteristics in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Hanan M Al-Kadri,1 Azza Madkhali,1 Mohammed T Al-Kadi,2 Hanadi Bakhsh,1 Nourah N Alruwaili,2 Hani M Tamim21Department of Obstetrics and Gynecology, King Abdulaziz Medical City, King Saud Bin Abdulaziz University for Health Sciences, Riyadh, 2King Saud Bin Abdulaziz University for Health Sciences, Riyadh, Kingdom of Saudi ArabiaBackground: In this study, we aimed to assess the rate of adolescent delivery in a Saudi tertiary health care center and to investigate the association between maternal age and fetal, neonatal, and maternal complications where a professional tertiary medical care service is provided.Methods: A cross-sectional study was performed between 2005 and 2010 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. All primigravid Saudi women ?24 weeks gestation, carrying a singleton pregnancy, aged <35 years, and with no chronic medical problems were eligible. Women were divided into three groups based on their age, ie, group 1 (G1 <16 years, group 2 (G2 ?16 up to 19 years, and group 3 (G3 ?19 up to 35 years. Data were collected from maternal and neonatal medical records. We calculated the association between the different age groups and maternal characteristics, as well as events and complications during the antenatal period, labor, and delivery.Results: The rates of adolescent delivery were 20.0 and 16.3 per 1,000 births in 2009 and 2010, respectively. Compared with G1 and G2 women, G3 women tended to have a higher body mass index, a longer first and second stage of labor, more blood loss at delivery, and a longer hospital stay. Compared with G1 and G2 women, respectively, G3 women had a 42% and a 67% increased risk of cesarean section, and had a 52% increased risk of instrumental delivery. G3 women were more likely to develop gestational diabetes or anemia, G2 women had a three-fold increased risk of premature delivery (odds ratio 2.81, and G3 neonates had a 50% increased overall risk of neonatal complications (odds ratio 0.51.Conclusion: The adolescent birth rate appears to be low in central Saudi Arabia compared with other parts of the world. Excluding preterm delivery, adolescent delivery cared for in a tertiary health care center is not associated with a significantly increased medical risk to the mother, fetus, or neonate. The psychosocial effect of adolescent pregnancy and delivery needs to be assessed.Keywords: adolescent pregnancy, maternal mortality, maternal morbidity, neonatal mortality, neonatal morbidity

Regional variations in the growth of Saudi children and adolescents  

International Nuclear Information System (INIS)

No previous study has provided a detailed description of regional variations of growth within the various regions of Saudi Arabia. Thus, we sought to demonstrate differences in growth of children and adolescents in different regions. The 2005 Saudi reference was based on a cross-sectional representative sample of the Saudi population of healthy children and adolescents from birth to 18 years of age. Body measurements of the length, stature, weight, head circumference and calculation of the BMI were performed according to standard recommendations. Percentile construction and smoothing were performed using the LMS (lambda, mu and sigma) methodology, followed by transformation of all individual measurements into standard deviation scores. Factors such as weight for age, height for age, weight for height, and head circumference for children from birth to 3 years, stature for age, head circumference and body mass index for children between 2-18 years of age were assessed. Subsequently, variations in growth between the three main regions in the north, southwest, and center of Saudi Arabia were calculated, with the Bonferroni: method used to assess the significance of differences between regions. There were significant differences in growth between regions that varied according to age, gender, growth parameter and region. The highest variation was found between children and adolescents of the southwestern region and those of the other two regions The regression lines for all growth parameters in children <3 years of age were significantly different from one region to another reaching - 0.65 standard deviation scores for the southwestern regions ( P =.001). However, the difference between the northern and central regions were not significant for the head circumference and for weight for length. For older children and adolescents a significant difference was found in all parameters except between the northern and central regions in BMI in girls and head circumference in boys. Finally, the difference in head circumference of girls between southwestern and northern regions was not significant. Such variation affected all growth parameters for both boys and girls. Regional variations in growth need to be taken into consideration when assessing the growth of Saudi children and adolescents. (author)

Body Mass Index and Dietary Intake of Saudi Adult Males in the Riyadh Region-Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available The aim of this study was to investigate intake of macronutrients and its relation to Body Mass Index (BMI as well as intake of selected micronutrients in urban and rural healthy adults in Riyadh region-Saudi Arabia. 170 health adults were recruited, 85 of which were urbans and 85 were rurals. Three consecutive days food records were collected and dietary intakes were analyzed by the food processor and other food composition tables. Results showed high intake of macronutrients and prevalence of overweight and obesity in both groups with no significant differences. Subjects of both groups also had high intake of saturated fat. Results also showed inadequate intake of vitamin D, calcium and folate. Few of the participants of both groups had inadequate intake of vitamin C. Intakes of vitamin B1, vitamin B3, iron, vitamin B12, vitamin B6 and vitamin B2 was adequate. No significant differences between the two groups were observed except for vitamin D, calcium and vitamin B2 that their mean intakes were significantly higher in urban group compared to rural group. Mean intake of vitamin B3 was higher in rural group compared to urban group. These findings suggested that overweight and obesity among adult Saudis are due to high intake of macronutrients combined with inadequate intake of some micronutrients, which are results of non-balanced diet and inappropriate consumption patterns. The study also suggests that there is a need of increasing the nutritional education and awareness among adult Saudi males.

Driving online shopping: Spending and behavioral differences among women in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available This study proposes a revised technology acceptance model that integrates expectation confirmation theory to measure gender differences with regard to continuance online shopping intentions in Saudi Arabia. The sample consists of 650 female respondents. A structural equation model confirms model fit. Perceived enjoyment, usefulness, and subjective norms are determinants of online shopping continuance in Saudi Arabia. High and low online spenders among women in Saudi Arabia are equivalent. The structural weights are also largely equivalent, but the regression paths from perceived site quality to perceived usefulness is not invariant between high and low e-shoppers in Saudi Arabia. This research moves beyond online shopping intentions and includes factors affecting online shopping continuance. The research model explains 60% of the female respondents’ intention to continue shopping online. Online strategies cannot ignore either the direct and indirect spending differences on continuance intentions, and the model can be generalized across Saudi Arabia.

Directory of Open Access Journals (Sweden)

Full Text Available Mostafa A Abolfotouh,1 Abdullah A Alabdrabalnabi,2 Rehab B Albacker,3 Umar A Al-Jughaiman,4 Samar N Hassan5 1King Abdullah International Medical Research Center (KAIMRC, King Saud bin Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia; 2University of Dammam, College of Medicine, Dammam, Saudi Arabia; 3King Saud University, College of Medicine, Riyadh, Saudi Arabia; 4King Faisal University, College of Medicine, Dammam, Saudi Arabia; 5Division of Reproductive Medicine, Department of Obstetrics and Gynecology, King Abdulaziz Medical City, Riyadh, Saudi Arabia Introduction: Infertility places a huge psychological burden on infertile couples, especially for women. Greater knowledge of the factors affecting fertility may help to decrease the incidence of infertility by allowing couples to avoid certain risk factors. The aim of our study was (1 to assess the knowledge and attitudes of infertile and fertile Saudi participants on infertility, possible risk factors, and social consequences; and (2 to determine the practices of infertile Saudi couples to promote their fertility before having them attend an in vitro fertilization (IVF clinic. Methods and materials: We conducted a cross-sectional study on 277 fertile participants from outpatient clinics and 104 infertile patients from the IVF clinic at King Abdulaziz Medical City between June 24, 2012 and July 4, 2012, using a previously validated interview questionnaire. Descriptive and analytical statistics were applied with a significance threshold of P ? 0.05. Results: A generally poor level of knowledge (59% and a neutral attitude (76% toward infertility were reported by participants. Mistaken beliefs commonly held by the study participants regarding the causes of infertility were Djinns and supernatural causes (58.8%, black magic (67.5%, intrauterine devices (71.3%, and contraceptive pills (42.9%. The healer/Sheikh was reported as the primary and secondary preference for infertility treatment by 6.7% and 44.2% of IVF patients, respectively. Compared with fertile patients, IVF patients were significantly less likely to favor divorce (38.5% versus 57.6%; P = 0.001 or marriage to a second wife (62.5% versus 86.2%; P < 0.001, if the woman could not have a baby. The patients with infertility had more favorable attitudes toward fertility drugs (87.5% versus 68.4%; P = 0.003 and having a test tube baby (92.4% versus 70.3%; P < 0.001. Child adoption was accepted as an option for treatment by the majority of IVF patients (60.6% and fertile outpatients (71.5%. Alternative treatments previously practiced by the IVF patients to improve fertility include practicing Ruqia (61%, using alternative medicine (42%, engaging in physical exercise (39%, eating certain foods (22%, and quitting smoking (12%. Conclusion: These findings have implications for health care providers regarding the reluctance that couples experiencing fertility problems may have, at least initially, to accept some interventions required for the couple to conceive.

Heavy Thunderstorm Synoptic Climatology and Forcing Mechanisms in Saudi Arabia.  

Science.gov (United States)

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. These forecasts become possible when the movement and the development of the mid-latitude disturbances are known very well. To further increase our understanding of the inter-annual variability of thunderstorms in semi-arid areas such as Saudi Arabia, it is necessary to consider the relationship between this variability and the large-scale atmospheric parameters in addition to the geographical features. Moreover, better insight into the monthly variations of the synoptic situations in Saudi Arabia is considered to be important for understanding the broad mechanisms responsible for thunderstorm occurrences in this geographical area. This information is highly important for aviation and other sectors in Saudi Arabia - both public and private. This paper aims to investigate the favourable synoptic environments for heavy thunderstorm initiation and development in Saudi Arabia. The importance of the monthly synoptic analysis of all days (1998-2003), heavy thunderstorm days, and dry days was intended to be demonstrated. Therefore, the monthly mean charts and deviations from the mean (anomalies) of specific meteorological parameters for heavy thunderstorm days and dry days for the months of January-December for the period 1998-2003, was illustrated to examine the synoptic conditions leading to heavy thunderstorm events in Saudi Arabia.

Susceptibility of Saudi Bulinus truncatus to infection with Egyptian Schistosoma haematobium with observations on protein electrophoretic pattern of the snails.  

Science.gov (United States)

A laboratory-based susceptibility study was carried out on snails Bulinus truncatus collected from highland Abha, Asser, Saudi Arabia to Egyptian Schistosoma haematobium to investigate the potential role of Saudi B. truncatus in the transmission of Egyptian S. haematobium and to know the possibility that the parasite might be able to spread into Saudi Arabia. The results revealed that, compared to Egyptian snails, survival of snails at day 25 post-exposure was significantly higher in Saudi B. truncatus ones. The infection rate was higher in Saudi snails as compared to Egyptian ones. The incubation period was shorter in Saudi snails but the duration of cercarial shedding was longer in the Egyptian than in the Saudi snails. The production of S. haematobium cercariae per snail was higher in Egyptian snails than in Saudi ones. These results suggest that Saudi B. truncatus can play a role in the transmission of Egyptian S. haematobium in Saudi Arabia and therefore this parasite might be able to spread into the Kingdom. In addition, electrophoretic analysis of tissue soluble proteins was done to determine the effects of the parasite on both the Egyptian and Saudi snails. The electrophoretic analysis revealed the occasional presence or absence of certain bands in infected snails in comparison with non-infected one. PMID:19329256

A multicultural nursing work force and cultural perspectives in Saudi Arabia: An overview  

Directory of Open Access Journals (Sweden)

Full Text Available This paper provides an overview of the cultural perspectives and practices in Saudi Arabia that could help expatriate health care providers to understand Saudi culture and enhance cultural competence. The healthcare system in Gulf countries, particularly, Saudi Arabia, is mainly staffed by expatriate nurses, who account for 67.7% of the total number of nurses. This gives rise to a multicultural environment in the hospital, where people of different cultures interact with each other and take care of Saudi patients who are from the dominant culture. In this scenario, a lack of knowledge of Saudi culture among nurses can lead to cultural conflicts and misunderstanding of some of the behaviours and practices of the indigenous Saudi people. Culture is a complex notion; however, being aware of cultural differences and having cultural knowledge can help people to interact safely. Educating expatriate nurses about the cultural heritage of the Saudi people, which is mainly influenced by Islamic teachings, is important to increase cultural harmony.

Eurasian and African mitochondrial DNA influences in the Saudi Arabian population  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Genetic studies of the Arabian Peninsula are scarce even though the region was the center of ancient trade routes and empires and may have been the southern corridor for the earliest human migration from Africa to Asia. A total of 120 mtDNA Saudi Arab lineages were analyzed for HVSI/II sequences and for haplogroup confirmatory coding diagnostic positions. A phylogeny of the most abundant haplogroup (preHV1 (R0a was constructed based on 13 whole mtDNA genomes. Results The Saudi Arabian group showed greatest similarity to other Arabian Peninsula populations (Bedouin from the Negev desert and Yemeni and to Levantine populations. Nearly all the main western Asia haplogroups were detected in the Saudi sample, including the rare U9 clade. Saudi Arabs had only a minority sub-Saharan Africa component (7%, similar to the specific North-African contribution (5%. In addition, a small Indian influence (3% was also detected. Conclusion The majority of the Saudi-Arab mitochondrial DNA lineages (85% have a western Asia provenance. Although the still large confidence intervals, the coalescence and phylogeography of (preHV1 haplogroup (accounting for 18 % of Saudi Arabian lineages matches a Neolithic expansion in Saudi Arabia.

Evaluating the role of health informatics professionals in saudi arabia: the need for collaboration.  

Science.gov (United States)

Saudi health authorities have acknowledged the role of health informatics professionals in improving the quality of medical services in Saudi Arabia. Different academic programs have been launched by different universities and medical colleges to produce qualified Saudi health informatics professionals. To date, there are no studies that have explained the role of health informaticians and their contribution towards the development of the Saudi health information infrastructure. In this study, the authors clarify health informatics practices and the different skills and job activities accomplished by health informaticians. With the growth in the number of Health Informatics programs within the country, there is a need to identify the current and future of HI professionals and to specify and clearly define the type of job titles describing health informatics roles. The Saudi HI educational programs need to work on linking their program objectives with a Saudi Health Informatics Career Framework (SHICF) and labor market needs. Ignoring such an important issue may result in unemployed Saudi HI graduates or HI graduates working in related fields other than HI. PMID:25000031

Risk factors associated with postpartum depression in the Saudi population  

Directory of Open Access Journals (Sweden)

Full Text Available Abeer A Alharbi,1 Hamza Mohammad Abdulghani2 1Department of Family and Community Medicine, 2Department of Medical Education, College of Medicine, King Saud University, Riyadh, Saudi Arabia Introduction: Postpartum depression (PPD is one of the major psychological disorders worldwide that affects both mother and child. The aim of this study was to correlate the risk of PPD with obstetric and demographic variables in Saudi females. Materials and methods: Data were collected by interviewing females 8–12 weeks postpartum. PPD symptoms were defined as present when subjects had an Edinburgh Postnatal Depression Scale score of 10 or higher. Variables included in this study were age, education, occupation, parity, baby's sex, pregnancy period, delivery type, hemoglobin level, anemia, and iron pills taken during pregnancy. Results: Of the 352 postpartum females, the prevalence of PPD symptom risk was 117 (33.2%. Among the PPD symptomatic females, 66 (39.8% had low hemoglobin levels, and 45 (40.5% females were anemic during pregnancy (P?0.05. These results suggest that early postpartum anemia, indicated by low hemoglobin level, is a significant risk factor for PPD (adjusted odds ratio 1.70, 95% confidence interval 1.05–2.74; P=0.03. Other variables, including age, parity, education, occupation, and delivery type, were not significantly correlated (P=0.15–0.95, but marginally indicative of the risk of depressive symptoms. Conclusion: Low hemoglobin level and anemia during pregnancy were risk factors for PPD in Saudi females. Many other factors may be considered risk factors, such as age, occupation, and parity. Anemic women need more attention and to be checked regarding their PPD, and treated if necessary. Keywords: postpartum depression, hemoglobin level, anemia, EPDS

Knowledge, attitude, and behavior among Saudis toward cancer preventive practice  

Science.gov (United States)

Objective: To examine self-reported knowledge, attitude, and preventive practices on cancer among Saudis. Materials and Methods: Data was collected from Saudis aged 15 years or more, who attended one of the randomly selected 20 Primary Health Centers (PHC) or the four major private hospitals located in the Riyadh region, either as patients or their escorts. The association between the variables was evaluated by the Chi square test. Results: The study population consisted of 618 males and 719 females. Among the female respondents 23.1% reported that they practiced breast self-examination (BSE); 14.2 and 8.1%, respectively, had clinical breast examination (CBE) and mammography. However, 10.0 and 16.1% of the females, aged 40 years and older, reported having had mammograms and CBE, respectively. The BSE performers were more educated, knew someone with cancer, and had heard of the cancer warning signal. Both educational level and ‘heard of cancer warning signal’ were significantly related to CBE. Cancer information was received from television / radio by 65.1% and from the physician by 29.4%. Even though 69.4% believed that cancer could be detected early, a vast majority (95.8%) felt early detection of cancer was extremely desirable and 55.1% said their participation was definite in any screening program. A majority of the respondents (92.6%) insisted on the need for physician recommendation to participate and 78.1% expected that any such program should be conducted in the existing hospitals / clinics. Conclusion: Culturally sensitive health education messages should be tailored to fulfill the knowledge gap among all population strata. Saudis will benefit from partnerships between public health educators and media to speed up the dissemination of cancer information. PMID:22175041

Nutrition Knowledge of Primary Care Physicians in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Several studies have indicated a lack of nutritional knowledge among physicians. As there is no published data in nutritional knowledge among physicians in Saudi Arabia, hence the purpose of this current study was to assess the nutrition knowledge of primary care physicians working in Riyadh, Saudi Arabia. Nutrition knowledge questionnaire consisted of 16 multiple-choice questions, was mailed to 105 primary care physicians working in Riyadh, Saudi Arabia. The questionnaire was pre- tested in a pilot study. Non-respondents received a second questionnaire and a phone call. Of the 105 primary care physicians, 59 replies were received (56.2%. The mean mark for correctly answered questions was 51.7%. Approximately 75 % of the physicians described their knowledge of nutrition as `Poor`. The results indicate that physicians are generally aware of information which has been publicized in the medical press: nutrient which helps prevent thrombosis (omega-3 fat; the preventive action of fruit and vegetables against cancer; which nutrients are antioxidants; the nutrient associated with the prevention of neural tube defects (folate. By contrast they have a poor knowledge of other important topics in nutrition: the major type of fat in olive oil; hydrogenated fats; source of vitamin B12; Substance raises the blood HDL-cholesterol level (Alcohol; the association between excess protein intake and calcium loss; the type of dietary fiber helpful in lowering the blood cholesterol level (soluble fiber and Nutrient is protective against hypertension. These results support other data that physicians need more education in nutrition. Nutrition should be an essential part in continuing medical education.

Organic geochemistry of the Paleozoic petroleum system of Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

The Palaeozoic petroleum system of the central and Northern Provinces of Saudi Arabia contains one of the most prolific oil-prone source rocks of Silurian age worldwide, the Qusaiba shale of the Qalibah Formation. This source rock is responsible for charging the large, gentle structures of the Central Province with billions of barrels of light, sweet, crude oil. Organic geochemical methods such as biomarkers, organic petrography, and characterization of the source rock facies have been used to determine the most likely candidate source rock for the Paleozoic oils of Saudi Arabia. By using detailed extract and oil characterizations, the basal hot shales of the Quasiba Member of the Silurian Qalibah Formation have been correlated to the oils reservoired in the Permian sands of the Central Province of Saudi Arabia. The Qusaiba shales consist of light to dark gray, clastic, marine shales and can be divided into two main zones: a low gamma-ray response and a high gamma-ray response, both having their own organic geochemical signatures. The low gamma ray zone has almost no source potential and comprises most of the Qalibah shale sequence. The hot gamma-ray zone is located at the base of the Qusaiba Member of the Qalibah Formation and consists of abundant amorphous matter, marine algae, acritarchs, and abundant chitinozoans and graptolites. Carbon isotopes and sterane biomarkers resulted in an excellent correlation between the basal Quasaiba shales and the oils. No other potential source rocks correlated as well, nor did these other potential sources contain the source rock quality, or vertical and lateral regional persistence as the Silurian basal Qusaiba shales. 51 refs., 25 figs., 3 tabs.

First shale gas experience in Saudi Arabia - lessons learned  

Directory of Open Access Journals (Sweden)

Full Text Available Influenced by the success of shale gas production worldwide and to meet requirements for clean energy supply, a multidisciplinary team of petroleum specialists was established in Saudi Aramco. Meeting the growing requirement in industrial consumption and especially electricity production is a driving force for developing unconventional gas reserves. ``The initial focus is in the northwest and in the area of Ghawar, where gas infrastructure exists. The company is innovatively combining knowledge and research to maximize gas reserves and production from conventional and unconventional resources in order to meet growing domestic demand (Saudi Aramco. 2010.During years 2010 - 2011 major international petroleum industry players - Schlumberger, Halliburton and Baker Hughes - were invited to share their experience in a series of workshops held in Dhahran. Exchange of expert ideas developed into appreciation of complexity of the shale gas reservoir and helped to identify the scope of work for the first Silurian Qusaiba shale gas well. The SHALE-1 well was drilled in 2007 as a gas exploration well. Recent drilling and geophysical data obtained in the well were beneficial for detailed sidetrack and fracture stimulation design.The Multidisciplinary task group was established and positioned in Dhahran. The draft work plan was developed 8 months before actual operations commenced on the well site. Thorough examination of the draft work plan progressed to the final work plan with a number of improvements. The Frac Stimulation design was fine-tuned, involving expertise from Saudi Aramco and Halliburton. The Complete Well on Paper exercise involved over 25 specialists from both companies and helped to rectify remaining completion/stimulation design issues, and put everyone on the same page in terms of the work program. Well site operations commenced in May 2011. All targets set for the SHALE-1 well were successfully achieved and the well was suspended for future utilization as an observation well.

Lifestyle factors associated with overweight and obesity among Saudi adolescents  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background A better understanding of the relationships between obesity and lifestyle factors is necessary for effective prevention and management of obesity in youth. Therefore, the objective of this study was to evaluate the associations between obesity measures and several lifestyle factors, including physical activity, sedentary behaviors and dietary habits among Saudi adolescents aged 14–19?years. Methods This was a school-based cross-sectional study that was conducted in three cities in Saudi Arabia (Al-Khobar, Jeddah and Riyadh. The participants were 2906 secondary school males (1400 and females (1506 aged 14–19 years, who were randomly selected using a multistage stratified cluster sampling technique. Measurements included weight, height, body mass index (BMI, waist circumference, waist/height ratio (WHtR, screen time (television viewing, video games and computer use, physical activity (determined using a validated questionnaire, and dietary habits (intake frequency per week. Logistic regression was used to examine the associations between obesity and lifestyle factors. Results Compared with non-obese, obese males and females were significantly less active, especially in terms of vigorous activity, had less favorable dietary habits (e.g., lower intake of breakfast, fruits and milk, but had lower intake of sugar-sweetened drinks and sweets/chocolates. Logistic regression analysis showed that overweight/obesity (based on BMI categories or abdominal obesity (based on WHtR categories were significantly and inversely associated with vigorous physical activity levels (aOR for high level?=?0.69, 95% CI 0.41–0.92 for BMI and 0.63, 95% CI 0.45–0.89 for WHtR and frequency of breakfast (aOR for? Conclusions The present study identified several lifestyle factors associated with obesity that may represent valid targets for the prevention and management of obesity among Saudi adolescents. Primary prevention of obesity by promoting active lifestyles and healthy diets should be a national public health priority.

Pathology of skin diseases. A study from Western Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Objectives: To describe the histopathological pattern of skin diseases in patients from the western region of Saudi Arabia and to compare this with previously published data from other regions in Saudi Arabia and worldwide. Methods: A retrospective review of all skin biopsies received and reported by the Department of Pathology, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia between January 2005 and December 2010. Neoplastic and non-neoplastic category were divided into melanocytic and non-melanocytic subcategories. Non-neoplastic category was divided into the following subcategories: dermatitis, infection, vascular, vesiculobullous, connective tissue disease, drugs, panniculitis, non-infectious granuloma, degenerative, metabolic, and pigmentary. Results: Three hundred and sixty skin biopsies were reviewed. Out of these, 207 (57.5% were non-neoplastic skin diseases, while 153 (42.5% were neoplastic. Both non-neoplastic (female to male ratio of 1.3:1 and neoplastic (female to male ratio of 1.2: 1 categories were more common in females than in males. Among the non-neoplastic category, the most common diagnosed subcategory was vesiculobullous disease (n=46, 22.2%, followed by dermatitis (n=30, 14.5%. The neoplastic category was divided into melanocytic (n=31, 20.3% and non-melanocytic neoplasms (n=122, 79.7%. Both neoplastic and non-neoplastic categories were most common in the age group of 46 years and older. Conclusion: Vesiculobullous diseases, dermatitis, and infections are the 3 most common non-neoplastic skin diseases and the most common neoplastic are benign non-melanocytic neoplasms. The prevalence of neoplastic and non-neoplastic skin diseases in general increases with age.

Desalination impacts on the coastal environment: Ash Shuqayq, Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

Ash Shuqayq (Saudi Red Sea coast) is approximately 28 km long and characterised by narrow rocky headlands with intermittent pocket beaches. Fifty-two sediment samples from six different environments (beach, dune, sabkha, tidal/lagoon, offshore and wadi) were analysed. Testing showed that beach and dune sands are mainly medium to fine grained, with some very coarse sand (MZ = - 0.59o). Both beach and dune sands are moderately well to moderately sorted, although some are poorly sorted due to an influx of wadi sediments. Sediment source together with littoral reworking contributed to grain size variation. Carbonate content varied between 1.5% and 23%, whilst the organic content varied between 1.1% and 13%. Spatial analysis showed increasing southward carbonate and organic content, with both correlated (r = 0.57). Sabkha sediments had significantly higher carbonate percentages (t = 2.898; df = 18; p < 0.01) and results suggested origins are similar for both UAE Arabian Sea and Saudi Arabian Red Sea coasts. X-ray diffractions show beach and dune sediments are mainly composed of detrital quartz and plagioclase feldspar with uncommon amounts of chlorites. Analysis of sediment characteristics, composition and shoreline distribution alongside coastal processes, indicate that high chlorite levels are probably caused by desalination processes. Due to human and ecosystem health consequences and the likely increased demand for desalination plants, similar analyses should be undertaken elsewhere, e.g. the Mediterranean. - Highlights: Black-Right-Pointing-Pointer New and previously unpublished Red Sea sediment information.

Science.gov (United States)

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

Prevalence of oral lesions among Saudi dental patients  

International Nuclear Information System (INIS)

Few studies have been conducted in the Saudi population on oral mucosal lesions. The purpose of this study was to evaluate the type and extent of oral lesions in a study among dental patients at a college of dentistry in Saudi Arabia. Over a 3-year period, 2552 dental outpatients were interviewed and investigated clinically for the presence of oral mucosal conditions. A thorough oral clinical examination was performed, including a radiographic examination. The diagnosis was confirmed histopathologically when necessary. Of 383 (15.0%) patients found to have oral mucosal lesions, females constituted 57.7% (n=221) and males 42.3% (n=162). The age range of the patients was between 15 to 73 years with a mean age of 38.2 years. The most commonly affected age group was 31 to 40 years, which comprised 21.4% (n=82) of all affected individuals. The least affected age group were individuals older than 61 years. The most common lesion was Fordyce granules (3.8%; n=98), followed by leukoedema (3.4%; n=86) and traumatic lesions (ulcer, erosion) in 1.9% (n=48). Tongue abnormalities were present in 4.0% (n=101) of all oral conditions observed, ranging from 1.4% (n=36) for fissured tongue to 0.1% (n=2) for bifid tongue. Other findings detected were torous platinus (1.3%; n=34), mandibular tori (0.1%; n=2) aphthous ulcer (0.4%; n=10), herpes simplex (0.3%; n=7), frictional hyperkeratosis (0.9%; n=23), melanosis (0.6%; n=14), lichen planus (0.3%; n=9) and nicotinic stomatitis (0.5%; n=1; n=9) and nicotinic stomatitis (0.5%; n=13). The findings of this study provide information on the types and prevalence of oral lesions among Saudi dental patients. This provides baseline data for future studies about the prevalence of oral lesions in the general population. (author)

A passive solar test facility for Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

A passive solar test facility has been designed for Dammam, Saudi Arabia. It will be located on the campus of King Faisal University, adjacent to the Persian Gulf. This maritime desert climate is terribly sevre, and one for which it is a formidable challenge to design a year around thermally efficient building. This facility incorporates seven different passive strategies: proper orientation, operable shading for windows, flow-through ventilation, externally insulated thermal mass, wind tower with direct evaporative cooling, indirect evaporative cooling through a double shell, and solar water heating. Construction should begin in June of 1983. Upon completion, the building will be monitored for at least two years.

Hypnotherapy for irritable bowel syndrome in Saudi Arabian patients.  

Science.gov (United States)

This study investigated whether hypnotherapy provides a significant therapeutic effect in Saudi Arabian patients with irritable bowel syndrome. Patients (n=26) were consecutively recruited at a psychiatry outpatient clinic after diagnosis by a gastroenterologist and a medical evaluation for irritable bowel syndrome. Each patient had 12 sessions of hypnotherapy over a period of 12 weeks (1 session per week). Patients completed a scale measuring symptom severity before and 3 months after the trial. Hypnotherapy significantly enhanced a feeling of better quality of life more in male than in female patients, and bowel habit dissatisfaction was reduced more in female than in male patients.

Hematologic risk factors for stroke in Saudi children  

International Nuclear Information System (INIS)

Objective was to explore the hematologic risk factors for stroke in cohort of Saudi children. We evaluated children at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, during the periods July 1992 to February 2001 (retrospective study) and February 2001 to March 2003 (prospective study). Investigations for suspected cases included neuroimaging, transcranial Dopppler (TCD) for cases of sickle cell diseases (SCD), and Duplex scan. Hemostatic assays included coagulation screening tests, tests of thrombin generation and fibrinolysis, coagulation inhibitors, and activated protein C resistance. During the study period, 104 Saudi children (aged one month to 12 years) with stroke were seen. The mean age of the cohort was 27.1 months (SD=39.3 months) and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). A major risk factor was identified in 93 of 104 cases of stroke (89.4%). Hematologic disorders were the most common (46.2%), followed by prothrombic disorders (31.7%); microcystic hypochromic anemia (26%); sickle cell disease (SCD), or SCB-thalassemia, (11.5%), and factor IX deficiency (2.9%). Raised anticardiolipin antibodies (13/49, 26.5%) was the most frequent abnormality. Deficiencies of the natural anticoagulants (protein S, protein C and antithrombin III) were as follows: protein S (15/70, 21.4%); protein C (15/70,21.4%) and combined deficiency of 2 or more inhibitors (9/70, 12.9%). Activated protein C resistance has not been detected. Contrary to the findings of previous studies from Saudi Arabia, SCD is a common risk factor and is severe, as it resulted in multiple strokes. Moyamoya syndrome was diagnosed in 2 patients with SCD, one of whom had revascularization surgery (encephaldoduroarteriosynangiosis). Assessment of children with SCD at a risk of stroke was helped by the introduction of TCD followed by neuroimaging, using MRI and magnetic resonanceangiography. The study strongly highlights the importance of prothrombotic disorders and the severe phenotype of SCD as risk factors for stroke in Saudi children. (author)

Application of using Hybrid Renewable Energy in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available One of the major world wide concerns of the utilities is to reduce the emissions from traditional power plants by using renewable energy and to reduce the high cost of supplying electricity to remote areas. Hybrid power systems can provide a good solution for such problems because they integrate renewable energy along with the traditional power plants. In Kingdom of Saudi Arabia a remote village called Al-Qtqt, was selected as a case study in order to investigate the ability to use a hybrid power system to provide the village with its needs of electricity. The simulation of this hybrid power system was done using HOMER software.

Trauma care systems in Saudi Arabia: an agenda for action  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Saudi Arabia is undergoing a rapid population growth that along with improved socioeconomics has led many individuals to own a car or even a number of cars per family, resulting in a greater number of vehicles on the roads. The reduced focus on good public transportation systems and the dependence on cars for transportation have created a diversity of drivers who are unfamiliar with the local driving rules and lack the basic skills for safe driving. This is in addition to some young drivers w...

Tertiary care availability and adolescent pregnancy characteristics in Saudi Arabia  

Science.gov (United States)

Background In this study, we aimed to assess the rate of adolescent delivery in a Saudi tertiary health care center and to investigate the association between maternal age and fetal, neonatal, and maternal complications where a professional tertiary medical care service is provided. Methods A cross-sectional study was performed between 2005 and 2010 at King Abdulaziz Medical City, Riyadh, Saudi Arabia. All primigravid Saudi women ?24 weeks gestation, carrying a singleton pregnancy, aged <35 years, and with no chronic medical problems were eligible. Women were divided into three groups based on their age, ie, group 1 (G1) <16 years, group 2 (G2) ?16 up to 19 years, and group 3 (G3) ?19 up to 35 years. Data were collected from maternal and neonatal medical records. We calculated the association between the different age groups and maternal characteristics, as well as events and complications during the antenatal period, labor, and delivery. Results The rates of adolescent delivery were 20.0 and 16.3 per 1,000 births in 2009 and 2010, respectively. Compared with G1 and G2 women, G3 women tended to have a higher body mass index, a longer first and second stage of labor, more blood loss at delivery, and a longer hospital stay. Compared with G1 and G2 women, respectively, G3 women had a 42% and a 67% increased risk of cesarean section, and had a 52% increased risk of instrumental delivery. G3 women were more likely to develop gestational diabetes or anemia, G2 women had a three-fold increased risk of premature delivery (odds ratio 2.81), and G3 neonates had a 50% increased overall risk of neonatal complications (odds ratio 0.51). Conclusion The adolescent birth rate appears to be low in central Saudi Arabia compared with other parts of the world. Excluding preterm delivery, adolescent delivery cared for in a tertiary health care center is not associated with a significantly increased medical risk to the mother, fetus, or neonate. The psychosocial effect of adolescent pregnancy and delivery needs to be assessed. PMID:24729733

Directory of Open Access Journals (Sweden)

Full Text Available This is the first report from Saudi Arabia studying the normal reference intervals in adult Saudi subjects and evaluating serum cystatin C as a prospective marker for the assessment of the glomerular filtration rate (GFR. Three hundred healthy adult Saudi subjects including 156 males (52% and 144 females (48%, with a mean age of 31.21 ± 9.82 years were prospectively studied to establish normal reference ranges for cystatin C. A total of 68.34% of the study patients were in the age-group of 21-40 years. The mean serum cystatin C in the 300 healthy subjects was 0.751 ± 0.11 mg/L (0.50 - 1.09, increasing gradually with age: it was 0.738 ± 0.11 mg/L (0.51 - 1.09 in the age-group 21 - 30 years and 0.807 ± 0.12 (0.51 - 1.09 among subjects who were > 50 years of age. The mean serum cystatin C in females (0.778 ± 0.118 mg/L was significantly hig-her than in males (0.726 ± 0.095 mg/L (p < 0.0001. The serum cystatin C level was within the defined reference range of 0.53 - 0.95 mg/L in 95% of the subjects with a mean value of 0.74 ± 0.097 mg/L, and was falling within the 95% confidence interval of 0.73865 - 0.7637 mg/L, and with 98.84% area under the curve (AUC. All the other renal function markers (urea, serum crea-tinine, calculated GFR, BMI among the studied subjects were within the normal reference ranges for adult Saudi population. The serum cystatin C level had a significant correlation with the body mass index (BMI (r = 0.155; p = 0.007 and a correlation with serum creatinine as well (r = 0.009; p = 0.873. It showed a negative correlation with calculated GFR as per Cockroft-Gault equation (r = - 0.101; p = 0.083.

Developing Saudi EFL Students’ Oral Skills: An Integrative Approach  

Digital Repository Infrastructure Vision for European Research (DRIVER)

This study investigates the problems of EFL/ESL university students’ unwillingness to speak and take part in class discussions. Saudi students find it inappropriate to speak in class because of their fear to be seen as verbally challenging their teachers' views openly and publicly. Even when they do, they speak a little.  This leads to frustration on the side of the teacher, in addition to the absence of any clear feedback from the students: whether they have/have not under­stood the lect...

The Ablah succession of Saudi Arabia (dating and geological significance)  

International Nuclear Information System (INIS)

The Ablah sedimentary succession represents a molasse basin in the Neo-Proterozoic Shield of Saudi Arabia. A rhyolite flow interbedded in the succession has been dated by the Pb/Pb method at 641± 1 Ma, indicating that the basin is a local expression of Panafrican tectonism in the south of the shield. Consequently, the Panafrican phase that has previously been described in the north can now be extrapolated to the south of the shield. This age determination also enables post-Panafrican events, which differ between the south and the north, to be analysed over the entire shield. (authors)

Medication burden of Saudi Arabian women receiving antiresorptive therapy  

Directory of Open Access Journals (Sweden)

Full Text Available Mir Sadat-Ali,1 Bader Al-Shafie,2 Abdallah S Al-Omran,1 Mohammed Q Azam11Department of Orthopedic Surgery, College of Medicine, University of Dammam, Dammam, Saudi Arabia; 2Department of Pharmacy, King Fahd Hospital of the University, Al Khobar, Saudi ArabiaBackground and purpose: Osteoporosis is common in the Saudi Arabian population, and its successful treatment requires full compliance. Patients who require antiresorptive therapy, such as oral bisphosphonates, may suffer from other diseases requiring medications, which increases the medication burden and ends up in drug noncompliance on the part of patients, making them vulnerable to osteoporosis-related fractures. We decided to undertake this study to analyze the concomitant medications that osteoporotic patients are receiving at King Fahd Hospital of the University, Al Khobar.Methods: Osteoporotic patients receiving antiresorptive therapy (ART at King Fahd Hospital of the University, Al Khobar, were identified through the database of the QuadraMed Patient Care system and cross-checked with the radiology database of the dual-energy X-ray absorptiometry scan and pharmacy drug-dispensing system between January 2009 and December 2009. Concomitant medication is defined as the use of other drugs for $30 days with oral bisphosphonates, calcium, and vitamin D. Medication burdens are defined as mild (?1 concomitant medication, moderate (?2 and ?4 medications, and severe (?5 medications. The demographic data, such as age, sex, and diagnosis, were collected from the medical records. The data were analyzed using the Statistical Package for the Social Sciences (SPSS.Results: During the study period, 516 patients were diagnosed with osteoporosis, and 473 were on ART while the rest were using anabolic Teriperatide. Sixty-eight (14.4% of the patients, with an average age of 50.15 ± 2.4 years, were on one medication besides ART, vitamin D, and elemental calcium; 129 (27.3% of the patients, with an average age of 51.6 ± 9.7 years, were taking 3.32 medications, and 276 (58.3% of the patients, with a mean age of 62.1 ± 10.7 years, were on 8.02 concomitant medications. The most common concomitant medications in use were cardiac, endocrine, systemic nonsteroidal anti-inflammatory drugs, and analgesics, in that order. This study suggests that the majority of Saudi women who are osteoporotic and undergoing oral bisphosphonate therapy have a concomitant medication burden of $5 other medications. For full compliance with the therapy, the patients' medication burden should be considered prior to selecting the treatment route.Keywords: osteoporosis, concomitant medications, polypharmacy, compliance

Perceived Barriers to Research Publishing in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Academic research represents the backbone of human activity in the way that it improves our quality of life through expanding frontiers of academic knowledge and making further research possible throughout the world. Academic research aims to provide solutions for many current problems. The importance of academic research has grown at universities and research centres in Saudi Arabia, fuelled by dramatic increases in governmental and private funding for research. This study focuses on the academic publication processes in Saudi Arabia, the barriers that affect researchers’ ability to carry out and publish research and the potential advantages and disadvantages offered by the Internet in the area of academic publishing. The data collection and analysis presented in this study addresses the extent to which such benefit could be realised in practice. This research reviews the limitations of research publishing in Saudi Arabia by focusing on the nature of academic journals, in terms of their numbers and purpose, the barriers that academic staff faced when they wished to publish their research work in local or international academic journals, and the attitudes of academics towards electronic publishing and publishing in general. This research uses questionnaire tool. The data are tabulated and analysed in a systematic method to show findings in accordance with required objectives. The most prominent findings from this study are the lack of academic staff encouragement to conduct and publish research, lack of financial support to the research publishing sector, lack of a research publishing infrastructure and a lack of private sector support for funding research and publishing. An interesting finding is that unlike many other countries, there is no culture of volunteering for work that does not provide direct financial benefit. This could be an important factor affecting the adoption of an online open publishing approach in which reviewers and editors are not paid directly for the work. This research ultimately aims at proposing and implementing suitable processes and policies to solve these problems and to identifying means of overcoming the research publishing barriers in Saudi Arabia.

Pubertal characteristics among schoolgirls in Riyadh, Saudi Arabia.  

Science.gov (United States)

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.

Sleep medicine in Saudi Arabia: Current problems and future challenges  

Directory of Open Access Journals (Sweden)

Full Text Available Sleep medicine is a relatively new specialty in the medical community. The practice of sleep medicine in Saudi Arabia (KSA began in the mid to late nineties. Since its inception, the specialty has grown, and the number of specialists has increased. Nevertheless, sleep medicine is still underdeveloped in the KSA, particularly in the areas of clinical service, education, training and research. Based on available data, it appears that sleep disorders are prevalent among Saudis, and the demand for sleep medicine service is expected to rise significantly in the near future. A number of obstacles have been defined that hinder the progress of the specialty, including a lack of trained technicians, specialists and funding. Awareness about sleep disorders and their serious consequences is low among health care workers, health care authorities, insurance companies and the general public. A major challenge for the future is penetrating the educational system at all levels to demonstrate the high prevalence and serious consequences of sleep disorders. To attain adequate numbers of staff and facilities, the education and training of health care professionals at the level of sleep medicine specialists and sleep technologists is another important challenge that faces the specialty. This review discusses the current position of sleep medicine as a specialty in the KSA and the expected challenges of the future. In addition, it will guide clinicians interested in setting up new sleep medicine services in the KSA or other developing countries through the potential obstacles that may face them in this endeavor.

A Phytogeographical Analysis of the Floristic Elements in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available An analysis has been carried out on the chorological units of Saudi Arabia. Three chorological units have been identified within the country, based on the richness of endemism. They are: Saharo-Sindian regional zone, Somalia-Masai regional centre of endemism and the Afro-montane archipelago-like regional centre of endemism. The Saharo-Sindian regional zone is divided into three subzones; of which, Nubo-Sindian local centre of endemism and the Arabian regional subzone are present in the Kingdom. The boundary line of the Nubo-Sindian local centre of endemism within Saudi Arabia has been extended towards the eastern region to cover most of the regions in the western Najd. The Somalia-Masai region contains the highest percentage (25.66% of species. The highest number of uni-regional endemics per unit area is found in the Afromontane archipelago-like regional centre of endemism while the lowest of that is in the Arabian regional subzone.

Knowledge and attitudes of saudi dental undergraduates on oral cancer.  

Science.gov (United States)

Oral cancer awareness among future dental practitioners may have an impact on the early detection and prevention of oral cancer. A cross-sectional survey was undertaken to assess the current knowledge of future Saudi dentists on oral cancer and their opinions on oral cancer prevention. A pretested questionnaire was sent to 550 undergraduate dental students in the fourth, fifth, and sixth year of the Al-Farabi College for Dentistry and Nursing, Riyadh, Saudi Arabia. Questions relating to knowledge of oral cancer, risk factors, and opinions on oral cancer prevention and practices were posed. Four hundred seventy-nine students returned the questionnaire (87.1 %). Eighty-one percent of respondents correctly answered questions relating to oral cancer awareness. Eighty-seven percent of respondents felt confident in performing a systematic oral examination to detect changes consistent with oral malignancy. Interestingly, 57 % of respondents had seen the use of oral cancer diagnostics aids. Thirty-seven percent of respondents felt inadequately trained to provide tobacco and alcohol cessation advice. There is a need to reinforce the undergraduate dental curriculum with regards to oral cancer education; particularly in its prevention and early detection. Incorporating the use of oral cancer diagnostic aids should be made mandatory. PMID:24699922

Evaluation of Saudi pegmatite and its use in porcelain industry  

Directory of Open Access Journals (Sweden)

Full Text Available Pegmatite is the main source of feldspar for ceramics industry. Usage of pegmatite in ceramic industry causes some problems due to the presence of mica and iron oxides. These materials reduce tile strength, hardness and density of the final product leading to low quality ceramic products. Southern Saudi pegmatite separation treatment was carried out in two phases in order to improve the ceramic quality of the feldspar obtained from this pegmatite. The first phase consists of gravitational separation to remove the heavy impurities and in the second phase magnetic separation was carried out to further minimize iron content. Porcelain ceramic batches were prepared by wet-mixing, drying, pressing (semi-dry press and fired at temperatures from 1000 to 1350 °C. The porcelain ceramic bodies were prepared and examined by DTA, X-ray diffraction, SEM and tested for bulk density, linear shrinkage, water absorption and flexural strength. These results indicated that, after treatment (gravity and magnetic separation, the pegmatite can be considered as a good source of potash feldspar. The present study provides a positive indication for using of Southern Saudi pegmatite after treatment in ceramic industries.

BK virus infection in a renal transplant Saudi child  

International Nuclear Information System (INIS)

BK human polyomavirus (BKV) causes an asymptomatic primary infection in children, but later, establishes latency mainly in the urinary tract. Virus-host interactions influencing persistence and pathogenicity are not well-understood. We present here a 12-year-old Saudi boy, who had renal transplant in Egypt. Seven months later, he was admitted to our Pediatric Nephrology Unit as a case of renal impairment. He developed BKV infection, diagnosed and successfully managed in our hospital. This case demonstrates the expanding clinical importance of BKV in a post renal transplant patient. This virus can be detected in transitional cells in the urine (decoy cells) using cytology. Testing for BKV deoxyribonucleic acid in urine and blood is an early detection assay, and can be used as a screening test in the early stages. The early reduction of immunosuppression can improve the prognosis. No specific antiviral treatment has been established yet. This is the first report of detecting BK virus in a Saudi post-transplant child in urine and blood specimens by using polymerase chain reaction. (author)

The knowledge of breast cancer among young Saudi females  

International Nuclear Information System (INIS)

To assess the breast cancer knowledge level of Saudi female school students.A detailed questionnaire on cancer breast was designed with all the needed information. Using a map of the Jeddah area of Saudi Arabia, schools were identified in each area and permission was sought from the Ministry of Education to distribute the questionnaire to the students. A team of volunteers was instructed on how to distribute and collect the questionnaires. The collected questionnaires were then statistically analyzed. This Pilot study of 500 students was performed in King Abdul-Aziz University Hospital using high schools from the city of Jeddah between April and June 2009. The results were used to build up a base for designing a community educational program. Analysis of the data from 337 questionnaires from high school and college students showed that the level of knowledge of young females on breast cancer is limited. However, it also indicated that the students are very enthusiastic to learn about cancer breast, and its prevention. The limited knowledge level of breast cancer in the younger generation might be an obstacle to screening programs and early diagnosis. Awareness programs should be developed including lectures, seminars workshops, and on hands training (Author).

Sand Dune and Sabkha Vegetations of Eastern Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available A study was conducted during 2006 and 2007 in Eastern Saudi Arabia to provide the needed information about the vegetation of sand dunes and sabkhas in the region and to provide insight into the factors controlling community distribution. Eastern Saudi Arabia with arid climatic conditions has sparsely distributed sand dune and sabkha vegetation cover. The vegetation comprises of perennial herbs, dwarf shrubs and few tree species. Seven major plant communities were recognized according to their dominant and co-dominant species: Panicum turgidum-Stipa capensis, Panicum turgidum-Pennisetum divisum, Panicum turgidum-Zygophyllum coccineum, Lasiurus scindicus-Stipagrostis plumose, Aeluropus lagopoides-Halopeplis perfoliata, Tamafix arabica-Aeluropus lagopoides and Zygophyllum coccineum-Cyperus conglomeratus. The seven communities represented different combinations of species. Soil organic carbon, soil salinity and soil water holding capacity appear to have a substantial influence on determining vegetation composition and abundance. In general, there are 45 species in the study area differing in their relative abundance, frequency and richness.

Differences in prostate cancer detection between Canadian and Saudi populations  

Scientific Electronic Library Online (English)

Full Text Available SciELO Brazil | Language: English Abstract in english 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. Ser [...] um 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

An aerobiological survey of allergens in al Khobar, Saudi Arabia.  

Science.gov (United States)

A nationwide aerobiologic study is in progress in Saudi Arabia using Burkard 7-day volumetric spore traps to determine the major airborne allergens and their seasonal patterns. Eights months readings have been completed at Al-Khobar, an important coastal city on the Arabian Gulf. Pollen levels showed a double season. An autumnal peak reached its maximum in October rising sharply from the low summer values before falling during the short winter then rising again in springtime. Both local and imported flora were represented with chenopodiaceae, grasses and Ambrosia as the most common botanical groups, identification of the most significant individual species is still in progress. Fungal spores also show distinctive seasonal patterns. In descending rank order from the most common genera were Cladosporium, Ustilago, Alternaria, with Chaetomium and Ulocladium as consistent but minor components. Basiodiospores and Ascospores represented less than 10% of the total spore population, indicative of the dry nature of the climate. Desert dust added an important irritant to the Saudi atmosphere but a major contaminating factor to the aerobiological material being analysed. PMID:2789674

Risk factors associated with postpartum depression in the Saudi population  

Science.gov (United States)

Introduction Postpartum depression (PPD) is one of the major psychological disorders worldwide that affects both mother and child. The aim of this study was to correlate the risk of PPD with obstetric and demographic variables in Saudi females. Materials and methods Data were collected by interviewing females 8–12 weeks postpartum. PPD symptoms were defined as present when subjects had an Edinburgh Postnatal Depression Scale score of 10 or higher. Variables included in this study were age, education, occupation, parity, baby’s sex, pregnancy period, delivery type, hemoglobin level, anemia, and iron pills taken during pregnancy. Results Of the 352 postpartum females, the prevalence of PPD symptom risk was 117 (33.2%). Among the PPD symptomatic females, 66 (39.8%) had low hemoglobin levels, and 45 (40.5%) females were anemic during pregnancy (P?0.05). These results suggest that early postpartum anemia, indicated by low hemoglobin level, is a significant risk factor for PPD (adjusted odds ratio 1.70, 95% confidence interval 1.05–2.74; P=0.03). Other variables, including age, parity, education, occupation, and delivery type, were not significantly correlated (P=0.15–0.95), but marginally indicative of the risk of depressive symptoms. Conclusion Low hemoglobin level and anemia during pregnancy were risk factors for PPD in Saudi females. Many other factors may be considered risk factors, such as age, occupation, and parity. Anemic women need more attention and to be checked regarding their PPD, and treated if necessary. PMID:24570584

Calculation of sky turbidity in the Kingdom of Saudi Arabia  

Science.gov (United States)

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.

Allergic fungal sinusitis in children in Saudi Arabia  

International Nuclear Information System (INIS)

Objective was to report the allergic fungal sinusitis (AFS) in children in Saudi Arabia and to review the experience of King Abdul-Aziz University Hospital in diagnosis and management of AFS in children. Hospital charts of 45 children reviewed retrospectively. Clinical presentation, radiological and operative findings, management and outcomes studied. Only 25 patients had >-4 diagnostic criteria, treated endoscopically between January 2000 and December 2005 and followed at least 2 years in KAUH, Riyadh, Kingdom of Saudi Arabia. Twenty-five patients had at least 4 criteria for AFS> All patients underwent functional endoscopic sinus surgery (FESS) with high recurrence rate 44%. Twenty-eight percent needed revision surgery even with medical treatment post operatively. Moreover, no other complications were reported in this study. Aspergillus spp is the most common fungal type in our review. Allergic fungal sinusitis in children is underestimated and understudied associated with poor outcome and high recurrence because of difficulty in management. Therefore, the most effective approach of AFS management in children is to have a high index of suspicion, adequate, preoperative evaluation, medical preparation preoperatively, meticulous surgery, medical management, postoperative including topical and systemic corticosteroids and close clinical follow-up with endoscopically guided debridement.

Assessment of Flood Hazard of Jeddah Area 2009, Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Due climatic variability and anthropogenic changes, floods have been raised lately in several regions worldwide. The resulting impact from floods is often harmful. This can be applied to Saudi Arabia, the country which is known by dry climatic conditions, and it became lately a typical region for such natural hazard. Hence, floods are observed as a yearly disaster with high magnitude of influence. Jeddah, a coastal Saudi city on the Red Sea to the west, has witnessed severe event in November 2009, when flooded water and sediments (torrents invaded the urban areas and resulted decease of many people and destroyed the infrastructure and civilized zones. The lack of mitigation implements exacerbated the problem. This study implies an assessment of flood hazard risk in Jeddah region. It aims to identify the zones subjected to flood and then inducing the influencing factors at different levels of effect. For this purpose space techniques were utilized, with a focus on IKONOS satellite images, which are characterized by high resolution in identifying terrain features. In addition Geographic Information System (GIS was also used to support space techniques. Thus, damaged areas and the mechanism of flooding process were recognized. This helps avoiding further urban expansion in areas under flood risk and will aid decision maker to put new strategies for hazard management.

Determination of Prevalence of Strangles in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Strangles is one of the most important infectious diseases that affect the respiratory system of the horse. The disease is characterized by fever, nasal discharges and enlargement of the associated lymph nodes. Strptococcus equi the causative agent of strangles, is a Gram positive bacteria. The goal of this study is to determine the prevalence of strangles among horses residing on horse farms in main regions of the Kingdom of Saudi Arabia. To achieve this goal, field visits were made to horse farms in Al-Ahsa, Dammam, Jubail, Riyadh, Jeddah and Tayf. A total of 75 farms that contain 926 horses were visited. Farm owners and managers were questioned regarding the presence of signs similar to strangles. In the meantime, horses were clinically evaluated. This survey indicated no horses were strangles confirmed. Finally, 35 horses admitted to the Veterinary Teaching Hospital at King Faisal University were examined. These horses were admitted for signs of respiratory disorders. Physical and endoscopic examination as well as bacterial culture indicated they were strangles free. Strangles seems not to be a threat to horses in Saudi Arabia.

Quality assessment of various bottled waters marketed in Saudi Arabia.  

Science.gov (United States)

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.

Energy and exergy utilization in transportation sector of Saudi Arabia  

International Nuclear Information System (INIS)

In this paper we present an analysis of energy and exergy utilization in the transportation sector of Saudi Arabia by considering the sectoral energy and exergy flows for the years of 1990-2001. Energy and exergy analyses are conducted for its three subsectors, namely road, air and marine, and hence the energy and exergy efficiencies are obtained for comparison. Road subsector appears to be the most efficient one compared to air and marine subsectors. It is found that the energy efficiencies in air and marine subsectors are found to be equal to the corresponding exergy efficiencies due to the values of exergy grade function. A comparison of the overall energy and exergy efficiencies of Saudi Arabian transportation sector with the Turkish transportation sector is also presented for the year 1993 based on the data available. Although the sectoral coverage is not same for both countries, it is still useful to illustrate the situation on how subsectoral energy and exergy efficiencies vary over the years. Turkish transportation sector appears to be a bit more efficient for that particular year. It is believed that the present technique is practical and useful for analyzing sectoral energy and exergy utilization to determine how efficient energy and exergy are used in transportation sector. It is also be helpful to establish standards, based on exergy, to facilitate applications in industry and in other planning processes such as energy planningergy planning

Full Text Available Ibrahim G Alghamdi,1 Issam I Hussain,1 Mohamed S Alghamdi,2 Mohamed A El-Sheemy1,3 1University of Lincoln, Brayford Pool, Lincoln, UK; 2Ministry of Health, General Directorate of Health Affairs, Al-Baha, Kingdom of Saudi Arabia; 3Research and Development, Lincoln Hospital, Lincolnshire Hospitals NHS Trust, Lincoln, UK 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 patients.

Usefulness of molecular techniques to identify ongoing tuberculosis transmission in Saudi Arabia  

International Nuclear Information System (INIS)

This study represents the first time that molecular tracing techniques have been used to identify patterns of tuberculosis TB infection in Saudi Arabia. The 2 strains were isolated from a socio-economically advantaged family who share a number of common facilities including a car and a driver. There are several factors that may play vital roles in on-going transmission of TB in Saudi Arabia including a high number of expatriates, the Hajj pilgrimage, and the social habits of Saudi citizens. Our sibling case series is believed to be a frequent pattern of disease transmission in this country. Control measures such as health education, active case finding, and prompt and supervised medical treatment are needed. More studies using molecular techniques are recommended to find the incidence of cross infection in Saudi Arabia. In addition, molecular techniques have to be established in all reference laboratories to help the detection of ongoing active transmission, molecular epidemiology and detect sources of infection.

Road Traffic Accidents in Saudi Arabia: An ARDL Approach and Multivariate Granger Causality  

Directory of Open Access Journals (Sweden)

Full Text Available The present paper examine the nexus between road traffic accident (RTA and some relevant variables in Saudi Arabia over the period 1971- 2012, using the autoregressive distributed lag ARDL model (Pesaran and Shin, 1999 for co-integration in Saudi Arabia, with the co-integration test. Results show that the variables are co-integrated in Saudi Arabia, moreover, the overall Granger causality results present that road traffic accidents, population and GDP, road mails, registered vehicles, and the number of driver license are Granger-causes each other in Saudi Arabia. With these findings, we affirm that there is a strong relationship and effect between road traffic accidents and its population, GDP, road mails, registered vehicles, and the number of driver license. The findings suggest that the  coefficients are negative signed and statistically significant in all VECMs, implying that there is bi-directional causality between the variables of interest in the long run.

The prerequisite for competition in the restructured wholesale Saudi electricity market  

International Nuclear Information System (INIS)

Protection of customers against monopoly is the first and main objective of the Saudi Electricity and Co-generation Regulatory Authority (ECRA). The second important objective, as recommended by the present study, is regulating natural monopoly businesses [Saudi electricity national grid (SENG) and Saudi electricity distribution (SED)] in addition to promoting real competition in competitive businesses [power supply providers (PSPs) and customer service providers (CSPs)]. Another four main objectives of ECRA are to promote the efficient use of energy and natural resources, to ensure a reasonable rate of return for PSPs and CSPs and at the same time to be fair to end-users, to ensure reasonable charges to SENG and SED services to be adequate for them to run the organization in a break-even manner and to maintain the system's security and reliability.

Measuring the Performance of Internal Audit Function in Saudi Listed Companies: An Empirical Study  

Directory of Open Access Journals (Sweden)

Full Text Available This study aims to explore whether Saudi listed companies are using performance measures to evaluate their internal audit function and, if they are, what performance measures they use to evaluate internal audit function and the identity of the important measures from the perspective of internal auditors. A questionnaire was designed and distributed to internal auditors in Saudi listed companies. The results show that Saudi listed companies are using both quantitative and quantitative performance measures to assess the internal audit function performance. Also, we find that internal auditors rank quantitative measures as important while qualitative measures are ranked as unimportant. The current study contributes to the existing literature by identifying key performance measures for the internal audit function in an emerging market, and provides valuable information about how to measure internal auditing performance. Also, this study is considered as the first one in Saudi market that identify such variable.

Recent petroleum exploration and development in Saudi Arabia; Saikin no Saudi Arabia no sekiyu tanko to kaihatsu  

Energy Technology Data Exchange (ETDEWEB)

This paper presents recent petroleum exploration and development in Saudi Arabia. At present Saudi Arabia yielding crude oil of 8 million BPD is the biggest oil yield and export country in the world. The estimated amount of oil deposits of nearly 2.6 hundred billion bbl accounts for nearly 25% of that over the world. Oil exploration was started by American enterprise in 1933, and a promising oil deposit was first confirmed in carbonate rocks in Jurassic Arabian stratum in 1938. The survey area of oil exploration gradually expanded up to all of eastern provinces and Arabian Bay. Ghawar oil field largest in the world and Safaniya oil field largest in the world as marine oil field were found in 1948 and 1951, respectively. Oil exploration in Central Arabia started in 1988 after nearly 50 years from oil exploration in eastern provinces, and low-sulfur/super-light oil was found in Paleozoic sand rock stratum. Up to this day light oil was confirmed at 15 sites in these areas, and further oil exploration is now in promotion. 4 figs., 3 tabs.

Environmental benefits of energy efficiency and renewable energy in Saudi Arabia's electric sector  

International Nuclear Information System (INIS)

This paper provides an evaluation of the potential environmental impacts of electric system expansion in the Kingdom of Saudi Arabia. Environmental concerns are important to consider because they represent costs to society that are not typically reflected in the price that consumers pay for electricity. In past analyses of electric expansion options in Saudi Arabia, the tendency has been to stress the direct financial costs of expanding electricity generation, transmission, and distribution infrastructure without characterizing the environment impacts of building and operating the expanded electricity system in monetary terms. Emerging national and global environmental concerns, however, suggest that an expansion of the methods traditionally used for electricity resource planning and selection to include environmental considerations would greatly benefit the Kingdom. The criteria by which resource plans are evaluated can readily be broadened to address environmental and other concerns. As part of an illustrative Integrated Resource Planning (IRP) effort undertaken by a team of Saudi utility planners and international consultants, an expanded IRP framework was used to assess the environmental costs and benefits of various approaches to meeting electricity demand projections in Saudi Arabia. The results show that making use of renewable energy and energy efficiency resources to provide energy services to the electricity consumers of Saudi Arabia can provide significant s of Saudi Arabia can provide significant environmental benefits for the Kingdom

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 p p p Conclusions The high prevalence of sedentary behaviors, physical inactivity and unhealthy dietary habits among Saudi adolescents is a major public health concern. There is an urgent need for national policy promoting active living and healthy eating and reducing sedentary behaviors among children and adolescents in Saudi Arabia.

Impact of software and hardware technologies on occupational health and safety policies in Saudi Arabian oil refineries.  

Science.gov (United States)

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 proposed by the Ministry of Labor. American and Saudi workers are concerned about the quality and sufficiency of health and safety training, employment promotion, work pressure, and job uncertainty due to continuous downsizing. This article recommends that Saudi social actors increase safety and health awareness in the work environment by providing intensive occupational safety training to the employees (as demanded by Saudi and American workers), improve labor-management relations through establishing strong cooperative contacts with regional and international trade unions, and establish uniform and standard occupational health and safety regulations for Saudi Aramco and its subsidiaries in order to provide an equal level of protection for Saudi workers.

Stroke due to mitochondrial disorders in Saudi children  

International Nuclear Information System (INIS)

Objective was to report on the clinical and biochemical features of patients who presented with stroke due to mitochondrial disorders amongst a prospective and retrospective cohort of Saudi children. Children, who presented with stroke were evaluated at the Division of Pediatric Neurology, or admitted to King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia, during the periods July 1992 to February2001 (retrospective study)and February 2001 to March 2003 (prospective study). Open muscle biopsies were obtained from patients suspected to have mitochondrial disorders, and examined using conventional histological and histochemical techniques. Biochemical, molecular pathological investigations, or both, of muscle could be arranged for only some of the patients. Mitochondrial disorders were the underlying risk factor for stroke in 4 (3.8%) of 104 children (aged one month to 12 years). Three patients (one male and 2 females) had Leigh syndromes (LS) and one had mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS). At the time of stroke, the 3 children with LS were 11 months, 15 months, and 7 years old. They presented with psychomotor regression and seizures. Muscle histology and histochemistry showed mild non-specific changes but no ragged red fibers. Biochemical analysis of muscle (in one patient) revealed deficiency of pyruvate dehydrogenase complex. Analysis of mitochondrial DNA (mtDNA), [the other 2 patients] was negative for the 2 point mutations (T-G and T-C) at nucleotide position 8993, and for two T-C point mutations (at position 8851 and 9176 of the ATPase 6 gene) that have been described in patients with LS. The girl with MELAS syndrome presented with a stroke-like episode at the age of 29 months and had focal brain lesions in the media aspect of the left occipital and temporal lobes, and in the posteromedial aspect of the left thalamus, which resolved within 7 weeks. She had raised cerebrospinal fluid lactate but no ragged red fibres on muscle histochemistry. Biochemical assay of muscle homogenate showed reduction in respiratory chain complexes I, III and IV. Mutation screening of mtDNA at nucleotides 3243 (tRNA) and 8344 (tRNA) was negative. Mitochondrial disorders constitute a risk factor for stroke in Saudi children. However, demanding and highly specialized investigations are needed to confirm the diagnosis. These are better performed at supraregional centers where facilities for clinical biochemical and molecular work-up are available. (author)

Measurement of quality in Saudi Arabian service industry  

Energy Technology Data Exchange (ETDEWEB)

Quality problems in the service organisation are the result of the mismatch between prior expectation and perceived quality of the service. Each organisation will attempt to determine the requirements of its customers and translate these requirements into product and delivery process specifications. This paper examines a particular electric company (SCECO-East), a typical service provider in Saudi Arabia, in which service quality is a distinguishing feature of primary importance. It describes a detailed survey and analysis in the light of the model put forward by Parasuraman et al. It utilises SERVQUAL for measuring customers' perceptions of service quality. The study revealed that SCECO-East scored high in tangibles dimension but low in features of responsiveness and reliability. In addition, while the performance of SCECO-East was acceptable to all customer categories, service quality was perceived differently by various types of customers, with reinforcement and commercial customers awarding SCECO-East even lower ratings than other customers did.

Temperature increasing trend due to solar activity at Western Saudi  

Science.gov (United States)

The Sun influnce on climate has been discussed globaly by many authors and at different latitudes. In this article we will discuss this connection for the Kingdom of Saudi Arabia, which spans a large area, i.e. 16-32 North and 36-50 East. We started our invistigation in this paper by looking into the temperature at the Western coast of the Kingdom, namely Yenbo and Jeddah. In order to find the correlation between temperature and solar variations we employed one of the most relevant solar quentity, i.e. the solar cycle length. From our invistigations we found an increase in the temperature averages reaching up to 1.0 degree Celsius in certain cities since 1970. It is also found that the temperature increase is strongly correlated with the solar Cycle length, reaching up to 0.8 in some sites.

The occurrence of indoor allergens in Saudi Arabia.  

Science.gov (United States)

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.

Pattern of cancer deaths in a saudi tertiary care hospital.  

Science.gov (United States)

The medical records of deceased patients were reviewed to describe the pattern of cancer deaths in a newly established Saudi tertiary care hospital. During eleven months, 87 patients died of cancer. The majority (80 patients, 92%) died of incurable cancer; among which 53% did not receive any systemic anti-cancer therapy (SAT) and 43% received SAT with palliative intent. Younger age (14 days and 14% died in intensive care unit or emergency room. The results demonstrate that palliative care is a realistic treatment for the majority of patients in our setting and that a significant proportion of these patients receive aggressive care at the end-of-life. There is a need to establish an integrative palliative care program to improve the quality-of-life of dying cancer patients in our region and to minimize the aggressiveness of end-of-life care.

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.

Antifungal Activity of Some Saudi Plants Used in Traditional Medicine  

Directory of Open Access Journals (Sweden)

Full Text Available Methanolic, chloroform and aqueous extracts of 11 medicinal plants used in folklore medicine in Saudi Arabia, were investigated for in vitro activity against four pathogenic fungi. The extracts at concentration of 0.5 mL plate-1 showed varying degrees of total inhibition of fungal growth. Extracts from Salvadora persica and Vigna fragrans showed the highest activity, followed by Peganum harmala and Withania somnifera, while Polycarpaea corymbosa demonstrated the least activity, when compared to 25 ?g mL-1 Clotrimazole control antibiotic. The fungal strains tested differed significantly in their susceptibility to plant extracts, with complete inhibition in Aspergillus fumigatus and Candida albicans. The plants which exhibited a marked antifungal activity were shown to be rich in alkaloids, flavanoids, tannins and glycosides. These results support the traditional use of these plants in the treatment of some fungal infections.

The changing face of healthcare in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Many countries now struggle to provide cost-effective, quality healthcare services to their citizens. Saudi Arabia has experienced high costs along with concerns about quality of care in its public facilities. To address these issues the country is currently restructuring their healthcare system to privatize public hos--pitals and introduce insurance coverage for both foreign workers and citizens. The changes provide an interesting and insightful case for the challenges in radically changing a country?s healthcare system. The situation also demonstrates a unique case in the Middle East for greater reliance of the private sector to address rapidly escalating healthcare costs and deteriorating quality. The complexity of changing a healthcare system is discussed with the many challenges associated with the change.

Saudi Arabia to build another world-scale plant  

Energy Technology Data Exchange (ETDEWEB)

Saudi Methanol Co. (AR-RAZI), a 50-50 joint venture of Sabic and a consortium of Japanese companies led by Mitsubishi Gas Chemical (MGC), says it will invest more than $200 million in a new 850,000-m.5./year chemical-grade methanol plant at Al Jubail. The plant, Ar-Razi`s fourth methanol unit, is scheduled for completion in May 1999. The jv will bring its third methanol plant onstream in July. This unit, also 850,000 m.t./year, will raise Ar-Razi`s total capacity to 2.25 million m.t./year. Its complex at Al Jubail is already the largest single producer of chemical-grade methanol in the world. When the fourth unit comes onstream in 1999 the jv will have 3.1 million m.t./year of methanol capacity.

Market Based Mergers- Study on Indian & Saudi Arabian Banks  

Directory of Open Access Journals (Sweden)

Full Text Available This paper analyses the efficiency and performance of post merger using CRAMEL–type variable of selected private banks in India & Saudi Arabia which are initiated by the market forces. The results suggest that the mergers did not seem to enhance the productive efficiency of the banks as they do not indicate any significant difference. The financial performance suggests that the banks are becoming more focused on their retail activities (intermediation and the main reasons for their merger is to scale up their operations. However, it is found that the loan to total Assets and the profitability are the two main parameters which are to be considered since they are very much affected by mergers. Also, the profitability of the firm is significantly affected after merger giving a negative impact on Earnings.

Measuring Studentsâ Beliefs about Physics in Saudi Arabia  

Science.gov (United States)

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.

Energy and exergy utilization in agricultural sector of Saudi Arabia  

International Nuclear Information System (INIS)

This paper presents an analysis of energy and exergy utilization in the agricultural sector of Saudi Arabia by considering the sectoral energy and exergy flows for a period of 12 years between 1990 and 2001. Energy and exergy analyses are conducted for its two essential devices, namely tractors and pumps, and hence the sectoral energy and exergy efficiencies are obtained for comparison for a period of 12 years. Two main energy sources are diesel for tractors and electricity for pumps in the sector. It is found that the overall exergy efficiencies in this sector are slightly less than the corresponding energy efficiencies, e.g. 74.19-69.20% for exergy efficiency and 74.94-74.60% for energy efficiency from 1990 to 2001. The present technique is proposed as a useful tool in sectoral analysis of energy and exergy utilization, developing energy policies and providing energy conservation measures

Implications of radiation monitoring for radwaste management in Saudi Arabia  

International Nuclear Information System (INIS)

Radioactive waste generated in Saudi Arabia has its origin in the use of various radionuclides in medical, industrial and research applications. Minimization of radwaste generation is an important aspect of good radwaste management. Towards this end surveillance of all establishments nation wide employing radionuclides was conducted. Data on the distribution of these establishments in the different cities and on the technical training of the employed radiation workers were gathered. Radiation monitoring of the radioisotope work areas for evidence of contaminations was carried out. Unnecessary generation of radwaste, if any, at whatever level of the respective application of isotopes was determined. Radwaste that will give trivial radiological risks is determined and is considered exemptible radwaste and hence the net radwaste destined for treatment will thus be minimized further

Geotechnical properties of expansive clay shale in Tabuk, Saudi Arabia  

Science.gov (United States)

Expansive soils prevail in several parts of Saudi Arabia. Tabuk city, in the northwest, is underlain by a shale formation of Ordovician to Devonian age. Arid climate accelerates the development of expansive clays through desiccation and weathering of the shale. The expansion of the city limits extends to potential areas of swelling and urbanization increases the clay moisture content which leads to soil volume change. This causes significant damage to low-rise buildings and pavements. In this paper, the subsurface conditions and geotechnical properties of the expansive soils in Tabuk are presented. The clay type was identified and its degree of expansion was determined. The swelling parameters were measured utilizing the standard oedometer test and modeled by multiple linear regression. The effect of geological and environmental conditions on the swelling behavior of expansive soils in Tabuk were considered. The modeled swelling values are in good agreement with the measured values.

Preliminary noise survey and data report of Saudi Arabian data  

Energy Technology Data Exchange (ETDEWEB)

From November 1995 to March 1996 a total of 9 broadband temporary stations were deployed across Saudi Arabian shield. These stations consisted of STS-2 seismometers recorded continuously at 40 sps on RefTek dataloggers. All installations were at bedrock sites. Using data sections selected randomly during the deployment, noise studies showed that most stations were exceptionally quiet with noise level near the USGS low noise model for frequencies higher than 0.1 Hz. At lower frequencies, the horizontal components showed increased noise levels, possibly due to instrumental characteristics. High-frequency (greater than 1 Hz) noise varied as much as 10 db between day and night for some stations (RAYN, TAIF) while more isolated stations (HALM) were constant. Seasonal noise levels also varied, with April to June being the quietest months. Slight changes in peak microseism frequency also occurred seasonally.

Prevalence of diabetes mellitus in a Saudi community  

Directory of Open Access Journals (Sweden)

Full Text Available Background and Objectives : Quantifying the prevalence of diabetes mellitus is important to allow for rational planning and allocation of resources. Therefore, we designed this study to determine the prevalence of diabetes among Saudi nationals. Design and Setting : A cross-sectional study among patients attending a primary care clinic in June 2009. Patients and Methods : Patients were interviewed with structured questionnaires to determine the presence of diabetes by questioning for history of the disease, and charts were reviewed to document any diabetic therapies that the patients may have undergone in the past or were undergoing at that time. Results : Of 6024 subjects, diabetes mellitus was present in 1792 (30% patients. The mean (SD age of the patients was 55.3 (13.2 years. The prevalence of diabetes was 34.1% in males and 27.6% in females (P<.0001. The mean (SD age for onset of diabetes in males and females was 57.5 (13.1 and 53.4 (13.1 years, respectively (P<.0001. Females <50 years old had a higher prevalence than males in the corresponding age range-34.1% and 25.1%, respectively (P<.0001. The prevalence of diabetes decreased in patients older than 70 years. The prevalence of body mass index of ?25 was 72.5%. Among patients with diabetes, the prevalence of body mass index of ?25 was 85.7% (P<.0001. There was a higher prevalence of obesity (body mass index, ?25 in females (87.7% as compared to males (83.1% (P=.008. Conclusion : The prevalence of diabetes is high among the Saudi population and represents a major clinical and public health problem. A national prevention program to prevent diabetes and address the modifiable risk factors at the community level, targeting high-risk groups, should be implemented soon.

Unusual Features of Rosacea in Saudi Females with Dark Skin  

Science.gov (United States)

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.

Microbial Contamination and Mycotoxins from Nuts in Riyadh, Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available The occurrence of harmful aflatoxins from agricultural products varies with geographic location, farming practices and processing. To date, no data was reported from Saudi Arabia on mycotoxin content of nuts and edible seeds. Forty samples of edible nuts and dried seeds were randomly collected from different locations in Al-Riyadh, Saudi Arabia. Fungi were detected by seed-plate and dilutions plate method and were cultured on glucose-Czapek's agar, sucrose-Czapek's agar and starch yeast agar. Purified fungal isolates were identified morphologically. Mycotoxins were extractedusing chloroform and detected by thin layer chromatography. Bacterial analysis was done using total plate count method. There was a predominance of A. niger and A. flavus in all medium types. Aflatoxin B1 (8.5 µg mL-1 was detected in peanuts containing A. flavus. Aflatoxin B1 (1.7 µg mL-1 and B2 (1.7 µg mL-1 was detected in sunflower seeds containing A. terreus. T2 toxin (2.8 mg mL-1 was detected in pumpkinseeds containing Stachybotrys chartarum and DAS (2.4 µg mL-1 was detected in a salted peanut sample containing Trichthecium roseum. Four nut samples showed contamination with bacteria. Turkish pine seeds and American walnut had total plate counts of 12x10. Pakistani pine seeds and Iranian salted pistachio had TPC of 3x10. Listeria monocytogenes was isolated from American walnut samples. Government authorities for food safety consumption should continue to monitor and set appropriate guidelines and information initiatives for public knowledge on the safety of these agricultural products whole year round.

Marjan Field system features coating innovations in Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

Innovations and advanced techniques in pipecoating and field joints for offshore pipelines are features of the 147-mile offshore oil and gas pipeline system installed for Aramco in the Marjan Field offshore Saudi Arabia. The project involved a network of oil and gas lines including 77 miles of 30-in. pipe, 62 miles of 36-in. pipe, and 8 miles of 16-in. pipe. Project is scheduled for completion by the end of 1984. Corrosion coating for all of the pipe, applied by Bredero Price Saudi Arabia Ltd., is 5/32-in. coal tar enamel over a synthetic primer, plus a reinforcing glass fiber wrap and an asbestos felt overwrap. Hevicote /SUP r/ concrete-weight coating was applied at a density of 190 lb per cu ft; thickness varies from 1- to 6.375-in. Pipecoating improvements pioneered in Europe for demanding North Sea projects were further developed by Bredero Price at its Jubail pipecoating facility for use on the Persian Gulf project. These included: Waterslotting. This is considered the most efficient method to control concrete cracking and subsequent spalling and to reduce stress on the concrete coating. Welded wire mesh. The 1.6 mm by 1.6 mm welded wire cross-sectional area is 36% greater than standard wire netting, increasing the amount of reinforcing steel in the concrete coating. New joint fill method. The Marjan project is the first offshore pipeline to use Joint Systems Corp's new IMAD automatic joint fill machine to coat the field joints on the pipe after welding and inspection.

The Saudi Arabian heat low: Aerosol distributions and thermodynamic structure  

Science.gov (United States)

Radiation and microphysical data are employed to deduce the bulk radiative and microphysical characteristics of the aerosol layer over the Saudi Arabian Peninsula and the adjacent Arabian Sea. Observed particle size distributions, total mass loadings, and vertical distributions of the dust are presented for five analysis periods. There is a large daily variability of the dust mass loading over the desert. The broadband radiative characteristics of the dust are inferred by comparing calculations for a dust free atmosphere with in situ broadband radiative measurements. The dust had no detectable effect on the longwave radiative fluxes, while it approximately doubled the clear sky shortwave absorption. The total shortwave absorption by the dust is dependent on the underlying surface albedo. The solar absorptance of the dust is expressed in terms of the dust mass loading and is incorporated into a broadband shortwave radiative transfer model to assess the surface and tropospheric energy budgets. For the desert cases the dust is largely responsible for a net 24 hour radiative energy convergence between, 530 and 800 mbar. A 24-hour radiative energy convergence is also found over the ocean; however, the layer depth is shallower than the desert case, being limited to the top of the dust layer. The thermodynamic structure of the heat low is presented. Calculations of temperature advection from the Saudi Arabian Peninsula to the Arabian Sea, suggest that horizontal advection aids in offsetting a net 24 hour tropospheric energy convergence over the desert. This warm air advection, along with the transport of dust over the Arabian Sea, may assist in maintaining the low level inversion and shallow moist layer observed over the western and central Arabian Sea.

Full Text Available Objectives: To present the incidence and spectrum of anorectal malformations (ARMs and associated anomalies and to compare the findings with published literature. Methods: This is a retrospective study conducted during the period January 2011 to December 2011. We reviewed the medical charts of all cases with ARMs admitted at Al-Madinah Maternity and Children Hospital, Madinah, Kingdom of Saudi Arabia during 1998-2010. The incidence and spectrum of ARMs, associated regional anomalies, and those with a positive family history of ARMs were identified. The 95% confidence interval and Chi square trend test were used to quantify the significance of variation in annual incidence. Results: One hundred eighty-eight cases of ARMs were detected from 189,145 live births with an incidence of approximately 1/1000 live births with a male-to-female ratio of 1.9:1. The incidence showed yearly stability (p=0.3509. The most common ARMs was perineal fistula (32.9%. There was a statistically significant gender difference (p=0.000. The most common in boys was rectourethral fistula (47.2% and in girls was vestibular fistula (46.2%. Isolated non-familial ARMs was found in 106 (56.3%, isolated familial 9 (4.7%, and associated ARMs in 73 (38.8% cases. In terms of associated anomalies, genitourinary (34%, and cardiovascular (19.2% systems reported a high incidence. Conclusion: The incidence of ARMs in Madinah Kingdom of Saudi Arabia, is higher than the reported data. Isolated ARMs was more common than the associated category, and the familial one was rarely reported.

Knowledge and Attitude of Saudi Health Professions’ Students Regarding Patient’s Bill of Rights  

Directory of Open Access Journals (Sweden)

Full Text Available 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. Method 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.

Prevalence of tobacco use and exposure to environmental tobacco smoke among saudi medical students in Riyadh, Saudi Arabia.  

Science.gov (United States)

This study was designed to determine the prevalence of active smoking and environmental tobacco smoke (ETS) exposure among medical students in Riyadh, Saudi Arabia, and to examine their attitudes and beliefs towards tobacco control programs. The investigation was a cross-sectional study conducted during the first semester of 2013 at King Saud University School of Medicine located in Riyadh, Saudi Arabia. Invited to participate in this study were 1,789 medical students. A descriptive data analysis was performed. A total of 805 medical students completed the questionnaire. The prevalence of experimentation with cigarette smoking was 11.3%. The estimated prevalence of current smoking among the study participants was 4.7%. The majority of the students held positive attitudes toward tobacco control and approximately 93.1% of the students felt that health care professionals should be required to receive training for cessation counseling while only 36.8% of the students reported having received any training in this area. Over the study's duration 57.7% of participants reported that ETS exposure was much higher in public places, while 13.9% reported exposure at home. This investigation revealed that ETS exposure among medical students in Riyadh is at an alarmingly high rate. The data suggests a need for a more robust smoke-free policy and a commitment to greater enforcement in public places. The results of the study also demonstrate a positive attitude among participants for tobacco control. It also indicates a need for cessation counseling and training which could be incorporated into medical school curriculum. PMID:24903238

The incidence rate of corpus uteri cancer among females in Saudi Arabia: an observational descriptive epidemiological analysis of data from Saudi Cancer Registry 2001-2008  

Science.gov (United States)

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 patients. PMID:24511244

Environmental benefits of energy efficiency and renewable energy in Saudi Arabia's electric sector  

Energy Technology Data Exchange (ETDEWEB)

This paper provides an evaluation of the potential environmental impacts of electric system expansion in the Kingdom of Saudi Arabia. Environmental concerns are important to consider because they represent costs to society that are not typically reflected in the price that consumers pay for electricity. In past analyses of electric expansion options in Saudi Arabia, the tendency has been to stress the direct financial costs of expanding electricity generation, transmission, and distribution infrastructure without characterizing the environment impacts of building and operating the expanded electricity system in monetary terms. Emerging national and global environmental concerns, however, suggest that an expansion of the methods traditionally used for electricity resource planning and selection to include environmental considerations would greatly benefit the Kingdom. The criteria by which resource plans are evaluated can readily be broadened to address environmental and other concerns. As part of an illustrative Integrated Resource Planning (IRP) effort undertaken by a team of Saudi utility planners and international consultants, an expanded IRP framework was used to assess the environmental costs and benefits of various approaches to meeting electricity demand projections in Saudi Arabia. The results show that making use of renewable energy and energy efficiency resources to provide energy services to the electricity consumers of Saudi Arabia can provide significant environmental benefits for the Kingdom.

Attracting Customer in Saudi Arabia to Buy from Your Business Online  

Directory of Open Access Journals (Sweden)

Full Text Available This paper reports on an exploration of the factors that attract consumers to buy online in Saudi Arabia. Fewcompanies in that country have enabled business sites, but most of them are keen to present product informationon their sites rather than have an online sales process. According to the latest report was issued in 2010 from theCommunications and Information Technology Commission (CITC in Saudi Arabia, there are only 8% ofbusinesses have online purchase channel; in contrast 54% of companies have websites only to present products.Accordingly, new research has been conducted to explore the attraction of customers in Saudi Arabia to buyfrom businesses online. This will assist the Small and Medium Enterprises (SME sector, which represents 90%of companies in Saudi Arabia, to increase communication channels with its customers electronically. Aquantitative survey was conducted on a random sample of 381 consumer participants from Saudi Arabia whowere interested to buy online to see what factors would attract them to online shopping. Several factors emergedas attracting factors which were divided into organizational, technical, and cultural factors.

Application of Johansen cointegration test finds the existence of a long run relationship among the chosen variables. All macroeconomic variables are found to impact stock prices. Standard and Poor 500 index does not affect Saudi stock prices. Vector error correction model shows the presence of long run causality from the explanatory variables to the stock prices. Short run causality test finds a two-way causality between stock prices and oil prices. Impulse response function shows that industrial production shocks pushes up stock prices while consumer price index shocks pulls it down. Variance decompositions show that historical stock prices are the major driver of Saudi stock prices. This implies that Saudi stock market follows weak form of market efficiency. The results of this paper have important implications for the investors in Saudi stock market.

Stock Market Volatility in Saudi Arabia: An Application of Univariate GARCH Model  

Directory of Open Access Journals (Sweden)

Full Text Available Study of stock market volatility has been the focus of financial economics. Modelling stock market volatility has great contributions to make in the areas of portfolio management, asset allocation, risk management, etc. We estimate the conditional volatility of Saudi stock market by applying AR (1-GARCH (1, 1 model to the daily stock returns data spanning from August 1, 2004 to October 31, 2013. We show that a linear symmetric GARCH (1, 1 model is adequate to estimate the volatility of the stock market of the country. We find that Saudi stock market returns are characterised by volatility clustering and follow a non-normal distribution. Saudi stock market returns show a time varying volatility, show persistence and are predictable. Past volatility impacts the current period volatility and past returns play a role in determining the current period return. Saudi stock market is nervous in its reactions to market fluctuations. This finding of the study offer important input into the decisions relating to asset allocation and risk management strategies of investors and treasury managers in Saudi stock market.

Emirati and Saudi Students’ Writing Challenges at U.S. Universities  

Directory of Open Access Journals (Sweden)

Full Text Available The study examines writing challenges Emirati and Saudi students face at U.S. universities. Based on a sample of 219, a mixed methods approach was used to analyze responses from the participants. The results of the questionnaire reveal that Less than 31% Emirati and Saudi students feel “comfortable” in completing written assignments. The interviews results indicate that Emirati and Saudi students have different opinions regarding writing difficulties. An Emirati student, stated: “I am worried a lot because writing is not easy. Writing is very difficult for us.” However, a Saudi student expressed the easiness of her writing assignments. Emirati students stated that grammar, word choice and sentence construction are “somewhat easy”; however, Saudi students indicated that grammar, word choice and sentence construction are “Somewhat difficult.” An Emirati student, stated: “Most Arabs students are told that we do not have vocabulary or grammar. For me, grammar is okay but my difficulty is how to choose the appropriate word for a sentence. A female Emirati student expressed her worry for grammatical mistakes, which she tries to correct: “When I write my reports, I have to reread my report again because I am sure I will have some grammatical mistakes because English is not my first language. The study implies that the students need more coursework in academic writing to prepare them for their academic writing in their disciplines. U.S. universities need to increase the visiting hours of writing centers and design more workshops that teach the students about writing in various genres.

Dental maturity of Saudi children: Role of ethnicity in age determination  

International Nuclear Information System (INIS)

Demirjian's dental maturity scores and curves have been widely used for human age determination. Several authors have reported considerable differences between the true and estimated age based on the Demirjian curves, which have been accounted for by ethnicity. The purpose of the current study was to assess the role of ethnicity-specific dental maturation curves in age estimation of Saudi children. A sample of 452 healthy Saudi children aged 4 to 14 years were aged based on the original French-Canadian Demirjian curves and several modified Demirjian curves specified for certain ethnic groups: Saudi, Kuwaiti, Polish, Dutch, Pakistani, and Belgian. One-way ANOVA and a post hoc Scheffe's test were used to assess the differences between chronological age and dental age estimated by the different curves (P<0.05). The curves designed for Dutch, Polish, Saudi, and Belgian (5th percentile) populations had a significantly lower error in estimating age than the original French-Canadian and Belgian (50th percentile) curves. The optimal curve for males was the Saudi one, with a mean absolute difference between estimated age and chronological age of 8.6 months. For females, the optimal curve was the Polish one, with a mean absolute difference of 7.4 months. It was revealed that accurate age determination was not related to certain ethnicity-specific curves. We conclude that ethnicity might play a role in age determination, but not a principal one.

FACTORS INFLUENCING E-COMMERCE ADOPTION BY RETAILERS IN SAUDI ARABIA: A QUANTITATIVE ANALYSIS  

Directory of Open Access Journals (Sweden)

Full Text Available This paper presents findings from a study examining the diffusion and adoption of online retailing in Saudi Arabia. Although the country has the largest and fastest growing Information and Communication Technologies (ICT sector in the Arab region, growth in e-commerce activities has not progressed at a commensurate rate. In general, Saudi retailers have not kept pace with the global growth of online retailing. The authors have conducted research to identify and explore key issues that influence Saudi retailers in deciding whether or not to adopt online channels. As part of a larger research project using mixed methods, this paper focuses on a quantitative analysis of responses obtained from a survey of retailers in Saudi Arabia. The design of the questionnaire instrument was based on the findings of a qualitative analysis reported in a previous paper. The main findings of the current study include a list of key factors that affect retailers’ e-commerce adoption, such as lack of online payment options and lack of clear legislation on e-commerce in Saudi Arabia, and quantitative indications of the relative strengths of the various relationships.

Assessing the current state of dental informatics in saudi arabia: the new frontier.  

Science.gov (United States)

Dental informatics is an emerging field that has the potential to transform the dental profession. This study aims to summarize the current applications of dental informatics in Saudi Arabia and to identify the challenges facing expansion of dental informatics in the Saudi context. Search for published articles and specialized forum entries was conducted, as well as interviews with dental professionals familiar with the topic. Results indicated that digital radiography/analysis and administrative management of dental practice are the commonest applications used. Applications in Saudi dental education included: web-based learning systems, computer-based assessments and virtual technology for clinical skills' teaching. Patients' education software, electronic dental/oral health records and the potential of dental research output from electronic databases are yet to be achieved in Saudi Arabia. Challenges facing Saudi dental informatics include: lack of IT infrastructure/support, social acceptability and financial cost. Several initiatives are taken towards the research in dental informatics. Still, more investments are needed to fully achieve the potential of various application of informatics in dental education, practice and research. PMID:25000042

A comparison of histological appearances of hodgkin disease in pakistani and saudi patients  

International Nuclear Information System (INIS)

Hodgkin's disease (HD) is a relatively rare lymphoma that affects younger as well as older persons. It is reported in the Western as well as Asian studies that HD is a rare disease in developing world. It is commoner in males in most of the countries and shows a bimodal pattern of age. The commonest subtype is nodular sclerosis in the west and mixed cellularity in the eastern and developing countries. The present study compares eight years' data of HD as regard age, sex, site of anatomical presentation and subtypes according to WHO classification among Pakistani and Saudi patients. This retrospective comparative study included 211 cases of HD from various institutions of Lahore, Pakistan and 78 cases retrieved from the data of King Abdul Aziz Hospital and Oncology Centre, Jeddah, Saudi Arabia. The analysis of both data of HD showed lack of bimodal age pattern and was common among younger age. Male was the dominating sex. Cervical group of lymph nodes was the commonest presenting site. Mixed cellularity HD (MCHD) was the commonest subtype among Pakistani patients whereas Nodular Sclerotic HD (NSHD) was more common among Saudis. A comparison of the pattern of Pakistani and Saudi data of HD showed lack of bimodality in both. The male sex predominated. Morphologically the MCHD and NSHD were the commonest subtypes in Pakistani and Saudi patients respectively. (author)

Abu Dhabi-Saudi Territorial Negotiations (1970-71: And the End of Britain’s Dominance in the Gulf  

Directory of Open Access Journals (Sweden)

Full Text Available The subject matter of this paper is the examination of the UAE-Saudi territorial negotiations from 1970-1971. This study discusses Britain’s mediation role in the Abu Dhabi-Saudi negotiations. Of particular note is Britain’s role, which focused on managing the dispute instead of settling the Abu Dhabi-Saudi border disputes. This serves as an example of Britain’s wish to avoid damaging its economic interests and political relations with either the UAE or Saudi Arabia. In line with this, the paper will examine King Faisal’s proposal of 1970, Shaikh Zayid’s position towards it and Saudi Arabia’s and Abu Dhabi’s negotiation strategies and tactics in settling the disputed areas. The paper offers a full explication of the major factors that hindered the dispute’s resolution before Britain officially withdrew from the Gulf.

Evaluation of the orthopedic residency training program in Saudi Arabia and comparison with a selected Canadian residency program  

Science.gov (United States)

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 (PEducational 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.

Stalled eruption or dike intrusion at Harrat Lunayyir, Saudi Arabia?  

Science.gov (United States)

Since 2007 there have been periodic small earthquake swarms recorded at seismic stations located around Harrat Lunayyir in northwest Saudi Arabia. In response to a longer-lived and larger seismic swarm, in early May 2009 the Saudi Geological Survey (SGS) installed a network of broadband seismometers surrounding the Harrat, with real-time data transmitted by VSAT back to its Earthquake and Volcano Center in Jeddah. The new network captured data from the swarm, which culminated with a M5.4 earthquake on 19 May that caused very minor structural damage in the town of Al Ays, 40 km to the southeast. Because of the strength of ground-shaking and resulting structural damage, the Saudi government evacuated more than 30,000 people from a 40 km radius surrounding Harrat Lunayyir, including the town of Al Ays. At the request of the SGS and the U.S. Consulate in Jeddah, the Volcano Disaster Assistance Program (a partnership program of the USGS and USAID’s Office of Foreign Disaster Assistance) sent two advisers to work with the SGS to determine if the unrest was volcanic in origin and to assess hazards associated with the unrest. The SGS-USGS team collected geologic, geodetic and seismic data that confirmed the volcanic nature of the activity. 1) A 3-km-long NW-trending surface rupture appeared in the central part of the Harrat before 19 May, during a time when maximum earthquake magnitudes exceeded M4. 2) The length of this rupture extended to 8 km with the M5.4 earthquake on 19 May. 3) The rupture opened 0.5 m and had an absolute motion of 0.9 m to N35W with a 63 degree plunge to the NE- a tensional offset consistent with that expected from an M5.4 earthquake in a rift-shoulder setting. 4) InSAR data showed about a meter of extension and uplift (as of July 2009) with the majority of deformation associated with the 19 May M5.4 earthquake. The InSAR-derived deformation field is best modeled by intrusion of a narrow (~2 m wide), 8-km-long dike to shallow crustal levels. 5) Finally seismic data showed features similar to other volcanic swarms, including high rates of occurrence of small events, shallow event locations that clustered beneath the lava field and were coincident with the area of maximum deformation, RSAM values that peaked during periods of increased InSAR inflation, and a mixture of event types- high frequency, low frequency, possible very low frequency, and tremor. Based on our analysis of similar active volcanic systems worldwide and associated earthquakes in rift settings, we determined that for the three month period following 19 May 2009 there was a moderate probability that the activity could culminate in an eruption, and a very low probability of additional large earthquakes of M6 or greater. Subsequent to this hazard assessment and once the stability of structures in Al Ays was adequately addressed, the evacuees were allowed to return to their homes and daily lives.

The Econometrics of Investment in Date Production in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Date palm is an important fruit crop in the Kingdom of Saudi Arabia and bears a lot on the national economy. Therefore, the government is paying special attention to date production through price support of low grade variety and providing subsidies to the most important production variables. The main objective of this study was to optimize the net present value of revenue to build a structural function of planting new date trees to explain and measure the investment decision. Because of inadequate information in this area, only the past investment period was considered to determine the effect of past decision on new decision of investment. The government policies, which directed to low grade varieties probably, led to inefficiency as the domestic consumption of dates is very high and growing high quality will lead to higher revenue to farmers with almost the same cost of production. To deal with investment in date palm production locally, Saudi Arabia needs to estimate a very high discount rate to observe any value related or based on the discount rate. The Durbin Watson parameter is significant for both the varieties (Khalas and Ruzaiz at 95% confidence interval (LSD0.05. The past investment appeared very significant for its effect on planting new date trees due to the fact that farmers who planted new trees in the past is continuously carrying with date industry and investing in future. Overall, the investment in tree plantation like date palm is not an easy decision by the farmers, because it needs couple of years spending without revenue. The farmers in the date growing areas were hesitant in providing information about the date variety, number of trees per hectare, tree age, fertilizers, pesticides, land ownership, intercropping, cost of production, total yield, quantity sold and price received. The study suggested further investigations on growing high quality date palms, date production and marketing aspects to harvest maximum profit by the farmers as well as support by the government for facilitating proper market and subsidies to date growers.

Efficacy of Pneumatic Dilatation in Saudi Achalasia Patients  

Science.gov (United States)

Background/Aims: Pneumatic dilatation (PD) is one of the effective treatments of achalasia. The aim of this study was to evaluate the efficacy of pneumatic dilation and patient satisfaction in Saudi achalasia patients. Patients and Methods: We have retrospectively recruited patients with confirmed achalasia, who underwent at least one dilatation session from January 1990 to January 2010 at a single tertiary center. Symptoms, including weight loss, dysphagia, retrosternal pain, and regurgitation, were assessed with the use of the Eckardt score (which ranges from 0 to 12, with higher scores indicating more pronounced symptoms). All patients were called and asked about their Eckardt score in addition to their satisfaction score post the dilatation procedure. The primary outcome was therapeutic success (Eckardt score ? 3) and patient satisfaction at the time of their calls. The secondary outcomes included the need for retreatment and the rate of complications. Results: A total of 29 patients were included, with a mean age of 40.30 (95% CI: 36.1-44.6) and 55.2% of them were males. The mean of the pre-dilatation Eckardt score was 8.3 (95% CI: 7.2-9.4), which dropped to 2.59 (95% CI: 1.7-3.5) after PD (P < 0.01) with a clinical remission of 76.7% after the first dilatation and a total failure in two patients (7%) after the third dilatation. The mean number of dilatations was 1.3 (95% CI: 1.1-1.5) where 50.7% required one dilatation, 19.2% required two dilatations, and 30.1% required three dilatations. The mean of the symptoms-free period was 53.4 months (SD 52.7, range 1-180) with symptoms recurring in 35% of patients within 2 years. The mean of post-PD patient satisfaction was 7.45 (95% CI: 6.2-8.7). Perforation, which was treated conservatively, occurred in one patient (3.5%), whereas bleeding occurred in two patients (7%). Age or gender was not found to be a predictor of Eckardt score improvement on multivariate linear regression analysis. Conclusion: PD is an efficacious procedure in Saudi achalasia patients with a very good overall patient satisfaction with 53.4 months of symptoms-free period after a successful dilatation.

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

Directory of Open Access Journals (Sweden)

Full Text Available 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.

Experience in and future prospects for sea water desalination in Saudi Arabia  

International Nuclear Information System (INIS)

The national programme for sea water desalination in Saudi Arabia is assigned to the Saline Water Conversion Corporation (SWCC), a government entity loosely affiliated with the Ministry of Agriculture. In addition to water production, SWCC generates considerable electric power in its dual purpose power/water plants, selling excess power to the national grid. SWCC also builds and maintains certain major fresh water pipelines that connect its plants to important municipal water systems. SWCC's pride is the Research, Development and Training Center (RDTC) located in Al-Jubail. The goals at RDTC include improving plant efficiency and minimizing scale formation and corrosion problems. It also trains Saudi engineers and technicians in the operation and management of SWCC plants. As a result, Saudi nationals now represent 65% of the workforce and are heavily involved with all aspects of plant specification and tender analysis

Fish consumption behavior and rates in native and non-native people in Saudi Arabia.  

Science.gov (United States)

Fish are a healthy source of protein and nutrients, but contaminants in fish may provide health risks. Determining the risk from contaminants in fish requires site-specific information on consumption patterns. We examine consumption rates for resident and expatriates in the Jeddah region of Saudi Arabia, by species of fish and fishing location. For Saudis, 3.7% of males and 4.3% of females do not eat fish; for expatriates, the percent not eating fish is 6.6% and 6.1% respectively. Most people eat fish at home (over 90%), and many eat fish at restaurants (65% and 48%, respectively for Saudis and expatriates). Fish eaten at home comes from local fish markets, followed by supermarkets. Saudis included fish in their diets at an average of 1.4 ± 1.2 meals/week at home and 0.8 ± 0.7 meals/week at restaurants, while expats ate 2.0 ± 1.7 meals/week at home and 1.1 ± 1.1 meals/week in restaurants. Overall, Saudis ate 2.2 fish meals/week, while expats ate 3.1 meals/week. Grouper (Epinephelus and Cephalopholis) were eaten by 72% and 60% respectively. Plectropomus pessuliferus was the second favorite for both groups and Hipposcarus harid and Lethrinus lentjan were in 3rd and 4th place in terms of consumption. Average meal size was 68 g for Saudis and 128 g for expatriates. These data can be used by health professionals, risk assessors, and environmental regulators to examine potential risk from contaminants in fish, and to compare consumption rates with other sites.

Saudi English-Major Undergraduates' Academic Writing Problems: A Taif University Perspective  

Directory of Open Access Journals (Sweden)

Full Text Available This study attempted to investigate Saudi English-major undergraduates studying at Taif University to identify a the types of academic writing Saudi English-major undergraduates carry out at English departments, b Saudi English-major undergraduates' writing problems, c the reasons behind Saudi English-major undergraduates' writing problems and d the solutions to overcome Saudi English-major undergraduates' writing problems. To collect data for this purpose, senior faculty members were interviewed and a 32-item structured Likert-scale questionnaire was developed that was administered to 75 English-major students (sophomores, juniors & seniors studying at foreign languages department, Taif University. Data generated through the questionnaire were subjected to descriptive analyses and mean and standard deviation were recorded using SPSS. The findings of this study reveal that Saudi English-major undergraduates are very weak in writing skills and commit lots of errors in their academic writings and are usually engaged in sentence-level or at the maximum at paragraph-level academic writing and they do not consider it important at this level to write different kinds of essays. It has been strongly recommended that the language courses should be increased to strengthen all the language skills in general and writing in particular, motivate the students to use English with the teachers as well as with each, introduce modern and novel teaching techniques, equip the classrooms with necessary audio-visual aids, diagnose students’ writing problems in the beginning of their studies at university, tailor the course contents according to their needs, introduce group/pair work, peer correction, use dictionaries frequently etc.

Precipitation Patterns Observed over the Southwest Region of Saudi Arabia  

Science.gov (United States)

During 2008 and 2009, an intensive field program has been conducted in the southwest region of Saudi Arabia, which is adjacent to the Red Sea and is bounded by the Yemen border to the south and the region around Jeddah to the north. The period of study focused on analysis of observations for the months of June-August. This period coincides with a climatological peak in precipitation over the region. This region is mountainous with terrain ranging from sea level to a maximum height of about 2800 m. During the field program, convection was observed almost daily during mid-afternoon was focused along the mountain peaks. This peak in convection coincided with the sea breeze reaching the top of the tallest terrain features. The intensity of convection was modulated by the strength of the sea breeze (predominate wind direction, amount of moisture in the boundary layer, etc.) and strength of a persistent mid-level inversion. The main objective of this study focuses on characterizing the spatial and temporal features of convection and related it to the atmospheric conditions that were observed during the months of June-August. The study examines precipitation and atmospheric conditions using a network of C-Band radars (Abha, Baha, Jeddah, Jizan, and Taif) and surface and upper data collected from the site located in Abha. The presentation will provide an overview of the field program and give a summary of the precipitation and atmospheric characteristics for the two years used in the study.

Financial Synergy in Mergers and Acquisitions in Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available Businesses today consider mergers and acquisitions a new strategy for their company’s growth. Companies aim to grow through sales’ increase, assets purchase, profits’ accumulation and market share gains. The better way for achieving these targets is by getting into either a Merger or an Acquisition. As a matter of fact, growth through mergers and acquisitions has been a critical part of the success of many companies operating in the new economy. Mergers and Acquisitions are an important factor in building up market capitalization. Based on three detailed and in depth structured interviews with major Saudi Arabian banks it has been found that, Mergers motivated by economies of scale should be approached cautiously. Companies should also approach vertical mergers cautiously because it is often difficult to gain synergy through a vertical merger and firms should also seek out mergers which allow the firm to acquire specialized knowledge. It has also been found that the firms should look for mergers that increase market power and avoid unrelated or conglomerate mergers.

Histologically diagnosed skin cancers, seen between 1990 and 2003, were reviewed and analyzed according to age, gender, race and site of distribution. Of a total of 193 patients, there were 79 (41%) cases of basal cell carcinoma (BCC), 56 (29%) cases of squamous cell carcinoma (SCC) and 34 (18%) cases of Kaposis sarcoma. Malignant melanomas represent 4.1% of the cases. The male to female ratio for all cancer was 1.6:1. The peak age distribution was in the 70-80-year group. The most common site involved in BCC was the head and neck (90%) and in Kaposis sarcoma were the lower limbs (59%). Acral distribution of malignant melanoma was seen in 62% cases. The most common skin cancers seen are BCC and SCC followed by Kaposis sarcoma. The site of distribution of BCC and SCC in our study is similar to studies in Caucasians. The site of distribution of BCC in sun exposed area supports the role of the ultraviolet light in the pathogenesis of such tumor. In contrast to the western countries, melanoma is a rare skin neoplasm in KSA. (author)

Passive cooling: Traditional climatic devices in Saudi Arabia  

Energy Technology Data Exchange (ETDEWEB)

In recent time the concern has been expressed by various individuals and government agencies not only about learning from the past experiences and achievements of the man as builder of his own environment but also about preservation and restoration of historic/traditional architecture from which there is a lot to learn. The traditional architecture with its climatic and cultural/communal solution also poses questions of how they could be utilized or transplanted in the new urban context. This paper is a brief review of a more detailed field and theoretical survey carried out by the author in his efforts to understand the role of climate in formation of the traditional environment in Saudi Arabia. The examples are only representative of the main aspects of the climatic response in traditional architecture in the four dominant climatic regions 1. Hot Dry, 2. Hot Humid, 3. Composite, 4. Upland. The nearby areas in the Eastern province as well as the far away places in the southern provinces are described from author's personal experiences. Most of the climatic design elements are discussed with illustrations. The presentation of the paper will be accompanied with colour slides (from which some of the diagrams are prepared) not included in the publication of this paper.

Food poisoning in Saudi Arabia. Potential for prevention?  

Directory of Open Access Journals (Sweden)

Food poisoning is becoming a very important health problem both internationally and in the Kingdom of Saudi Arabia (KSA. Salmonella species (spp is the most important pathogen, but due to the extensive effort carried by the health authorities to prevent or eradicate communicable diseases, new pathogens are now emerging such as Escherichia coli (E. coli and Norwalk like viruses. This review paper highlights the magnitude and determinants of food poisoning internationally and in KSA, and proposes some recommendations on its prevention. Clearly, there is a steady increase in the food poisoning accidents in KSA, especially during the summer months and Hajj season. These accidents are seen in other countries such as England, United States of America and Japan. Meat and chicken are the main items incriminated in these accidents. Knowledge on food safety in the food preparation process and the risk factors that can lead to food poisoning is low. Training and proper health education messages are needed to raise the awareness of food handlers as well as the public in general.

Knowledge of healthy diets among adolescents in eastern Saudi Arabia.  

Directory of Open Access Journals (Sweden)

Full Text Available BACKGROUND : Bad dietary habits, such as eating high-fat/high-energy food, can contribute to obesity in adolescents, which tends to persist into adulthood. The objective of this study was to determine the level and sources of knowledge about foods and healthy diets among male and female adolescents. METHODS : This was a cross-sectional study of a sample of male (n=1240 and female (n=1331 adolescents from third grade, intermediate and all three grades of secondary school students in the Al-Khobar Area, eastern province of Saudi Arabia. A self-administered questionnaire was used to collect information. RESULTS : Approximately 51% of the male and 65% of the female students recognized unsaturated fats as healthy foods. However, 10% of the males and 8% of females reported saturated fats as healthy food items. About 49% of the males and 66% of the females correctly defined cholesterol. Dietary knowledge of both male and female students on the dangers of unhealthy foods and the benefits of fiber-rich diets was found to be unsatisfactory. The main sources of knowledge about health and disease reported by the male and female respondents were television (58% and 61%, respectively, magazines (31% and 39% and daily newspaper (33% and 34%. Primary health care centers (PHCCs staff were the least source of knowledge (17% and 16%. CONCLUSIONS : Knowledge of healthy diets among school students was inadequate. It is recommended that health education and information about healthy eating habits and lifestyle be included in school curricula.

Measles in Saudi Arabia : From control to elimination.  

Directory of Open Access Journals (Sweden)

Full Text Available This article describes the tremendous efforts made in the field of measles immunization in Saudi Arabia in the past 20 years, from the control phase to the elimination phase. Mandatory measles vaccination with one-dose Schwartz vaccine was introduced in 1982 by a royal decree, a step aimed at increasing vaccine coverage. In 1991, a two-dose schedule was implemented using Edmonston-Zagreb measles vaccine , with a first dose at 6 months to protect children younger than 9 months and a second dose of MMR at 12 months of age to protect those who did not respond to the first dose. A marked reduction in the epidemic peak and a shift of infection to older age were noticed. But the same data showed that 50% of measles cases in the 1- to 4-year age group occurred in vaccinated children. In 1998, with the start of elimination phase, an MMR campaign was launched in two phases, targeting school children in 1998 (secondary schools and in 2000 (primary and intermediate schools. Evaluation of the MMR campaign and surveillance data was reflected in the measles immunization policy by shifting the age of measles immunization to 12 months and to preschool using the two-dose MMR schedule.

Systems modeling and analysis for Saudi Arabian electric power requirements  

International Nuclear Information System (INIS)

This thesis addresses the long-range generation planning problem in Saudi Arabia up to the year 2000. The first part presents various models for electric energy consumption in the residential and industrial sectors. These models can be used by the decision makers for the purposes of policy analysis, evaluation, and forecasting. Forecasts of energy in each sector are obtained from two different models for each sector. These models are based on two forecasting techniques: (1) Hybrid econometric/time series model. The idea of adaptive smoothing was utilized to produce forecasts under several scenarios. (2) Box-Jenkins time series technique. Box-Jenkins models and forecasts are developed for the monthly number of electric consumers and the monthly energy consumption per consumer. The results obtained indicate that high energy consumption is expected during the coming two decades which necessitate serious energy assessment and optimization. Optimization of a mix of energy sources was considered using the group multiattribute utility (MAU) function. The results of MAU for three classes of decision makers (managerial, technical, and consumers) are developed through personal interactions. The computer package WASP was also used to develop a tentative optimum plan. According to this plan, four heavy-water nuclear power plants (800 MW) and four light-water nuclear power plants (1200 MW) have to be introduced by the year 2000 in addition to sixteen oil-fired power plants (400 MW) and nine gas turbines (100 MW)

Uranium and trace elements in phosphate fertilizers--Saudi Arabia.  

Science.gov (United States)

Manufactured phosphate fertilizers and their agricultural applications are considerable sources of environmental pollution. In this study, composite samples of phosphate fertilizer (PF) of different physical forms (granular, G, and water soluble powder, L) were collected. The activity concentration of 238U in Bq kg(-1) was measured using gamma ray spectrometers, and the concentrations of arsenic, cadmium, copper, lead and selenium in mg kg(-1) were measured using inductively coupled plasma optical emission spectrometers (ICP-OES). The main aims of this study were to evaluate PF quality according to its physical form, determine manufacturers (local, L, or imported, I), and estimate the hazardous impacts of long-term phosphate fertilization. There was significant variation in the concentration of uranium and other elements in PF samples. In order to have globally normalized data, it is highly recommended to express the concentration of trace elements as per phosphorus mass instead of fertilizer mass. The annual addition of these elements to soil due to phosphate fertilization was calculated. The possible accumulation of added uranium and other trace elements due to fertilization in the subsurface soil layer and/or shallow underground water should be studied in the soil environment of Saudi Arabia.

Automated management of radioactive sources in Saudi Arabia  

Science.gov (United States)

For usage of radioactive substances, any facility has to register and take license from relevant authority of the country in which such facility is operating. In the Kingdom of Saudi Arabia (KSA), the authority for managing radioactive sources and providing licenses to organizations for its usage is the National Center of Radiation Protection (NCRP). This paper describes the system that automates registration and licensing process of the National Center of Radiation Protection. To provide 24×7 accesses to all the customers of NCRP, system is developed as web-based application that provide facility to online register, request license, renew license, check request status, view historical data and reports etc. and other features are provided as Electronic Services that would be accessible to users via internet. The system also was designed to streamline and optimize internal operations of NCRP besides providing ease of access to its customers by implementing a defined workflow through which every registration and license request will be routed. In addition to manual payment option, the system would also be integrated with SADAD (online payment system) that will avoid lengthy and cumbersome procedures associated with manual payment mechanism. Using SADAD payment option license fee could be paid through internet/ATM machine or branch of any designated bank, Payment will be instantly notified to NCRP hence delay in funds transfer and verification of invoice could be avoided, SADAD integration is discussed later in the document.

Metamorphic evolution of the Qazaz metamorphic complex, Saudi Arabia  

Science.gov (United States)

Precambrian accretionary orogens largely contributed to continental growth, owing to their high production rates of juvenile crust compared to Phanerozoic accretionary orogens. The Pan-African orogeny is responsible for the evolution and growth of the Arabian-Nubian Shield. The Qazaz metamorphic complex in Saudi Arabia is one of the metamorphic complexes that were exhumed due to the activity of the largest Proterozoic shear zone system on the Earth - the Najd Fault System. The Qazaz complex is an example of an unusual new type of core-complex associated with crustal scale strike-slip faulting. Petrography and thermodynamic modelling were used to study the metamorphic evolution of the complex. The core of the complex records peak metamorphic conditions of 560 - 640 oC and 7-8 kbar. The bounding strike-slip shear zones operated at a temperature range of 400-600 oC while the pressure range varied from 5 to 0.5 kbar over a very short distance within the shear zone. The complex shows exhumation of about 25 km due to the activity of the Najd Fault System.

Drug resistance patterns of acinetobacter baumannii in makkah, saudi arabia  

International Nuclear Information System (INIS)

Background: Acinetobacter baumannii causes infections of respiratory, urinary tract, blood stream and surgical sites. Its clinical significance has increased due to its rapidly developing resistance to major groups of antibiotics used for its treatment. There is limited data available on antimicrobial susceptibility of A. baumannii from Saudi Arabia. Objectives: To determine the patterns of drug resistance of Acinetobacter baumannii and predisposing factors for its acquisition.Subjects and Methods: In this descriptive study, 72 hospitalized patients infected with A baumannii were studied. The clinical and demographic data of the patients were collected using a predesigned questionnaire. Isolation and identification of A.baumannii from all clinical specimens were done using standard microbiological methods. Antibiotic susce ptibility testing was performed by disk diffusion method recommended by Clinical Laboratory Standards Institute. Results: Majority of the isolates (61.1%) were from respiratory tract infections. A.baumannii isolates showed high drug resistance to piperacil lin (93.1%), aztreonam (80.5%), ticarcillin, ampicillin, and tetracycline (76.4%, each) and cefotaxime (75%). Only amikacin showed low rate of resistance compared to other antibiotics (40.3%). About 36% patients had some underlying diseases with diabetes mellitus (11%) being the predominant underlying disease. Conclusions: High antimicrobial resistance to commonly used antibiotics was seen against A.baumannii isolates. Only amikacin was most effective against it. (author)

Osteoarthritis of knees and obesity in Eastern Saudi Arabia  

International Nuclear Information System (INIS)

Objective was to find out the prevalence and relation between osteoarthritis of knees and obesity in Al-Ahsa region, Kingdom of Saudi Arabia (KSA). The study included 243 male and female patients diagnosed with osteoarthritis of knees of knees in between June 2001 to March 2003. All patients were recruited from the Physical Therapy Department, King Fahd Hofuf Hospital, Hofuf, KSA. The clinical diagnosis was supported plain x-rays of knees, and of other joint if needed. The weight and height of all patients were taken using one standard weight and height scale, and body mass index was also calculated and recorded. More than 90.53% of the patients referred with osteoarthritis of knees were obese or overweight. The mean body weight of all patients was 84.61 kg and the mean weight was 1.59 meters. Osteoarthritis of the knees was more in obese female than male patients with a female to male ratio of 2.37:1. Obesity is a disease. The aim of all health professionals and others in the community should be directed to the prevention of this disease and its risk to develop multiple complications. (author)

Patterns of thyroid cancer in Southwestern Saudi Arabia  

International Nuclear Information System (INIS)

To examine the pattern of thyroid cancer, assess the magnitude of the problem, and evolve a management plan for such malignancies. This is a retrospective cohort study of all thyroid cases operated at Aseer Central Hospital, Abha, Kingdom of Saudi Arabia, between January 1998 and December 2007. Clinical presentations, management regimens, and recurrence were reviewed. Five hundred and sixteen patients were operated for different thyroid lesions. Ninety-two (17.8%) were malignant (20 males and 72 females). Mean age for males was 41.35 +/- 15.52 years compared to 36.59 +/- 13.28 years for females. Papillary carcinoma constituted 50%, while follicular carcinoma formed only 4.3% of malignant cases. Lymphoma ranked third with only 1.1% of all malignant thyroid lesions. No cases of medullary carcinoma were found. Of 92 patients, 75 reported for follow-up. The recurrence rate for follow-up patients was 29 (31.5%). High resolution neck ultrasonography and image-guided fine needle aspiration cytology should be considered as routine investigative tools in patients with suspicious thyroid swelling. Total thyroidectomy and removal of all lymph nodes in the central compartment of the neck seem to be the ideal management plan, until such trials emerge. Residual thyroid tissues, following surgery, should be ablated using radioiodine I131 isotope (Author).

Stratigraphic palynology of Devonian boreholes from northern Saudi Arabia  

Directory of Open Access Journals (Sweden)

Full Text Available This extended abstract describes well-preserved palynomorph assemblages recovered from Devonian strata in five shallow boreholes in the northern part of Saudi Arabia. These fully cored holes overlap stratigraphically to form a 1,640 ft composite section spanning the upper Tawil, Jauf and lower Jubah formations. Only the Jauf and lower Jubah, represented by 188 samples taken over a 1,300 ft stratigraphic interval, are addressed here as the sandy Tawil lithologies are unsuitable for palynological analysis. The 900 feet of alternating of siliciclastic and carbonate units, that together comprise the five members of the Jauf Formation, were sampled comprehensively. However, the Jubah Formation, like the Tawil Formation, is mostly sandstone and is productive palynologically at only two levels separated by a 300 ft barren interval. The age of the sampled succession is assessed using index species from the established Euramerican Devonian palynozonations of Richardson & McGregor (1986 and Streel et alii (1987, and is shown to span the late Early and Middle Devonian.

An Analysis of Learning Barriers: The Saudi Arabian Context  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Learning and teaching are quite interrelated. Teaching can't take place unless the students learn. Teaching is a bi-polar activity. Learning barriers or causes of learning difficulties are quite natural phenomenon in an educational setting. But, when it comes to exert a very adverse effect it becomes crucial. Thus, it is unavoidable to ignore those factors which adversely affect the entire learning process. It is found that the following barriers are some of those that are very influential: social, cultural, parental, attitudinal, motivational, psychological, personal and pedagogical factors that include teacher, action research, teaching strategies, teaching resource, administration etc. The present paper is going to focus on the following: motivation of the students, motivation of the teachers, dedication and commitment, teacher's role, teachers’ preparedness, teaching strategies, training and professional development etc. The case of Saudi Arabia is very important for many reasons. The government is spending a lot of money on education. But, the achievement of learning is not up to the mark. Therefore, it is important to study the effect of such factors on academic achievement. Keywords: Barriers, socio cultural factors, psychological factors, pedagogical factors, the teacher , motivation.

Gas bubble disease in farmed fish in Saudi Arabia.  

Science.gov (United States)

Four outbreaks of gas bubble disease were encountered among farmed fish in Saudi Arabia. Two of them occurred among subadult (52.5 g) saltwater tilapia (Oreochromis spilurus), the first affecting about 50 per cent of the stock and resulting in about 30 per cent mortality, and the second affecting about 25 per cent of the population with about 5 per cent mortality. Another outbreak occurred among adult (270 g) brackish water (0.5 per cent salinity) tilapia (Oreochromis niloticus), affecting about 40 per cent of the population with about 25 per cent mortality. The fourth outbreak occurred among three-month-old (15 g) grouper (Epinephelus fuscogutiatus) and resulted in 10 per cent mortality. In all cases the total water gas pressure ranged between 111.2 and 113.4 per cent saturation and nitrogen was supersaturated while oxygen was undersaturated. The outbreaks were alleviated by reducing the gas pressure by splashing the source water or by switching to a source of water with lower gas pressure. However, in O niloticus the conditions of gas supersaturation resulted in a heavy infection by monogenetic trematodes which was treated with formalin at 40 mg/litre for seven hours on five successive days.

Measurement of acoustical characteristics of mosques in Saudi Arabia  

Science.gov (United States)

The study of mosque acoustics, with regard to acoustical characteristics, sound quality for speech intelligibility, and other applicable acoustic criteria, has been largely neglected. In this study a background as to why mosques are designed as they are and how mosque design is influenced by worship considerations is given. In the study the acoustical characteristics of typically constructed contemporary mosques in Saudi Arabia have been investigated, employing a well-known impulse response. Extensive field measurements were taken in 21 representative mosques of different sizes and architectural features in order to characterize their acoustical quality and to identify the impact of air conditioning, ceiling fans, and sound reinforcement systems on their acoustics. Objective room-acoustic indicators such as reverberation time (RT) and clarity (C50) were measured. Background noise (BN) was assessed with and without the operation of air conditioning and fans. The speech transmission index (STI) was also evaluated with and without the operation of existing sound reinforcement systems. The existence of acoustical deficiencies was confirmed and quantified. The study, in addition to describing mosque acoustics, compares design goals to results obtained in practice and suggests acoustical target values for mosque design. The results show that acoustical quality in the investigated mosques deviates from optimum conditions when unoccupied, but is much better in the occupied condition.

Epidemiology of diarrhoea in two major cities in Saudi Arabia.  

Science.gov (United States)

The epidemiological pattern of diarrhoeal diseases, causative agents and risk factors of their occurrence in two referral hospitals of Saudi Arabia is presented in this study. Stool specimens from 1726 admitted diarrhoeal cases were examined for parasites, yeast, enteropathogenic bacteria and rotavirus using the ELISA test. 41.3% of cases were due to rotavirus (RVGE) while 53.1% of cases showed no causative pathogens. Mean age of all cases was 20.2 months and RVGE cases showed a steady rise from the neonatal period onward, reaching a peak between 6-14 months. Males accounted for higher percentage of all diarrhoeal cases. Mothers of diarrhoea cases were mostly housewives with low educational level. Bottle fed children showed higher proportion (53.1%) of diarrhoea than other types of feeding suggesting the faeco-oral route of infection and the effect of poor sanitation. A pattern of higher RVGE cases was seen in warmer months in Al-taif and in cooler months in Jeddah. Findings demonstrated the interaction between host, pathogen and environmental factors in the epidemiology of infectious diarrhoeas in developing countries and the areas of possible prevention.

Towards evidence-based clinical practice guidelines in Saudi Arabia.  

Directory of Open Access Journals (Sweden)

The objective of this review is to provide a brief background on clinical practice guidelines CPGs and tools to assess and locally adapt CPGs. Over the last 2 decades, CPGs have become an increasingly popular tool for synthesis of clinical information, so as to change clinical practice and improve quality of health care. Such a quantitative growth in the number of guidelines available in different specialties is a source of concern since there is evidence that recommendations produced by different groups can be conflicting, invalid, unreliable, and even harmful. Various critical appraisal instruments were designed and tested to assess whether developers have minimized the biases inherent in creating guidelines and addressed the requirements for effective implementation. We recommend using the AGREE instrument which was developed by the Appraisal of Guideline Research and Evaluation AGREE collaboration. It is the most well-developed guideline appraisal instrument available, and it has been shown to have good reliability and validity. There is a growing recognition that it is not possible for national guidelines to be produced on every clinical problem of concern. The cost is huge and few practices have the resources or skills to develop their own valid evidence-based guidelines. Several developed countries encourage local adaptation of international good quality guidelines to avoid duplication of work and cost involved in guidelines development. Therefore wherever possible, Saudi guidelines should be based on existing good quality guidelines. The methodology for local adaptation of CPGs to meet the local needs and resources are explained in this review.

Influence of age, sex, folate and vitamin B12 status on plasma homocysteine in Saudis.  

Directory of Open Access Journals (Sweden)

The first data on plasma homocysteine concentrations in Saudi healthy males and females are reported. Age and sex differences were confirmed and a significant inverse relationship between plasma homocysteine concentrations and that of serum folate and plasma vitamin B12 was observed. Various independent variables including age, sex, serum folate, waist-to-hip ratio and plasma vitamin B12 contributed to the changes in plasma homocysteine. Plasma homocysteine concentrations should be evaluated in patients at risk for cardiovascular and other related diseases in the Saudi population.

A cyclone over Saudi Arabia on 5 January 2002: A case study  

Science.gov (United States)

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.

Feedback on the Feedback: Sociocultural Interpretation of Saudi ESL Learners’ Opinions about Writing Feedback  

Directory of Open Access Journals (Sweden)

Full Text Available This qualitative study employed informal conversational interviews and semi-structured individual interviews to capture the Saudi students’ opinions about the feedback they receive, and about their perceptions on what constitutes helpful feedback. Sociocultural theory was used as the framework of this study. The findings suggest that the Saudi students do not think highly of the feedback, and that the feedback they desire is markedly different from what they receive. The students mentioned several impediments to feedback. From a sociocultural perspective, the feedback practices do not adhere to the best practices of the theory, resulting in major hindrances to the students’ learning/writing development.

Ultra-high CPV system development and deployment in Saudi Arabia  

Science.gov (United States)

This paper discusses the development and deployment of an ultra-high concentrating PV module that utilizes concentration above 1400X on multijunction solar cells. The development process included the selection of cell assemblies, primary and secondary optics, and focal distance. The systems were deployed in Saudi Arabia inside the Solar Village near Riyadh and in Khafji near the border of Saudi and Kuwait, following the deployment of first prototype in Yorktown, NY. Data from operation in those areas are shown here, and next steps of optimizing the module performance are discussed.

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. Keywords: Middle East respiratory syndrome, case fatality rate, descriptive epidemiology, temperature, humidity

Body mass index in Saudi Arabian children and adolescents: A national reference and comparison with international standards  

International Nuclear Information System (INIS)

Because there are no reference standards for body mass index (BMI) in Saudi children, we established BMI reference percentiles for normal Saudi Arabian children and adolescents and compared them with international standards. Data from a stratified multistage probability sample were collected from the 13 health regions in Saudi Arabia, as part of a nationwide health profile survey of Saudi Arabian children and adolescents conducted to establish normal physical growth references. Selected households were visited by a trained team. Weight and length/height were measured and recorded following the WHO recommended procedures using the same equipment, which were subjected to both calibration and intra/interobserver variations. Survey of 11 874 eligible households yielded 35 275 full-term and healthy children and adolescents who were subjected to anthropometric measurements. Four BMI curves were produced, from birth to 36 months and 2 to 19 years for girls and boys. The 3rd, 5th, 10th ,25th , 5oth , 75th ,85th , 90th , 95th , and 97th percentiles were produced and compared with the WHO and CDC BMI charts. In the higher percentiles, the Saudi children differed from Western counterparts, indicating that Saudi children have equal or higher BMIs. The BMI curves reflect statistically representative BMI values for Saudi Arabian children and adolescents. (author)

Iran’s Economic Considerations after the War and its Role in Renewing of Iran-Saudi Diplomatic Relations  

Digital Repository Infrastructure Vision for European Research (DRIVER)

Iran-Saudi relationship has constantly been frictional after Islamic revolution of Iran. In general, Saudi heavy support of Iraqi government during Iran-Iraq war and Iran’s holding political demonstration so-called the Liberation from Infidels gave rise to frigidity of mutual relations of the two countries. Meanwhile, one of the means that Saudi Arabia, as ally of Iraq, applied to put Iran under pressure was oil and reduction of its price in order to decrease Iran’s foreign exchange reven...
