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

    The unwarranted connection between diabetes mellitus and breast cancer has gained new ground in recent years. Breast cancer in Saudi females accounts for approximately 21% of all cancers and the prevalence of diabetes mellitus (DM) in Saudi females is also 21.5%. DM is diagnosed in the age group of 30+ years with possible exposure to predisposing factors like hyperinsulinemia and obesity at younger age. Further, 12% of the breast cancer cases are diagnosed in the young females aged 20-34 years. Despite the readily available access to healthcare facilities in the Kingdom, a large number of diabetics, approximately 27.9%, were unaware of having diabetes mellitus. This subpopulation is quite susceptible of developing breast cancer at later age. This review discusses common etiological and predisposing factors for breast cancer and diabetes, regional distribution and possible correlation of diabetes and cancer in Saudi Arabia.

    Full Text Available Jazan province is an arid area, located at the southwestern part of Saudi Arabia along the Red Sea coast. Groundwater is the only resource of drinking water in this area; thus, its suitability for drinking and domestic uses is of public and scientific concern. In this study, groundwater samples were collected from 23 sites in Jazan area during fall 2014; measurements and analysis of water quality parameters including pH, total dissolved solids TDS, turbidity, hardness, alkalinity, ammonia, nitrite, nitrate, sulfate, calcium, magnesium, chloride, iron and fluoride were carried out with references to WHO and Gulf Standardization Organization GSO. TDS values exceeded the permissible limit of 600 mg/l in 30.4% of samples, total hardness values exceeded the permissible limits of 300 mg/l in 34.8% of samples, and nitrate concentration exceeded the permissible limit of 50 mg/l in only one sample. However, the concentrations of investigated parameters in the groundwater samples were within the permissible limits of WHO. Our results showed that the water quality of groundwater in Jazan area is acceptable and could be used safely for drinking and domestic purposes. However, a special attention should be paid to the concentration of TDS and nitrate in groundwater in future studies.

    Saudi Arabia has experienced frequent occurrences of biological disasters due to a wide range of generator factors, including natural disasters and epidemics. A national survey (n=1,164) was conducted across 13 regions of Saudi Arabia to examine public perceptions to the risk of a biological disaster. The primary results reveal: (a) a degree of knowledge about biological threats such as SARS and H5N1 flu, despite the lack of individual experience with disasters; (b) age, gender, education and faith are positively related to the perception of biological risk; and (c) a number of important community resilience factors exist, including faith, education and willingness. This study concludes that the development of adapted resilience strategies in disaster management can be achieved through public education and training involving cooperation with official organisations and religious authorities in the country to increase public awareness, knowledge and skills in mitigating biological threats.

    Ectoparasitic arthropods are a diverse element of the Saudi fauna. Due to this, a survey of ectoparasites associated with rodents was conducted as a preliminary study in five districts of Hail region of northern Saudi Arabia for the first time. Ectoparasites extracted from 750 rodents were sampled and identified by recording their frequency of appearance. Results revealed that 1,287 ectoparasites infested 316 of the captured rodent hosts. These ectoparasites parasitized on four species of rodents including three species of rats Rattus rattus rattus, Rattus rattus frugivorus, and Rattus rattus alexandrinus and one species of mouse Acomys dimidiatus (Rodentia: Muridae). The ectoparasites belong to four different groups: ticks, fleas, lice, and mites. Ticks were the highest in the number, while fleas were the lowest among all the extracted ectoparasite groups. The collected ectoparasitic arthropods consisted of seven species. Ticks were of two species: Rhipicephalus turanicus and Rhipicephalus sanguineus (Acari: Ixodidae), fleas were of two species: Xenopsylla cheopis and Xenopsyllus conformis mycerini (Siphonaptera: Pulicidae), lice was a single species: Polyplax serrata (Anoplura: Hoplopleuridae), and mites were of two species: Laelaps nuttali and Laelaps echidninus (Mesostigmata: Laelapidae). The findings of the study showed that the intensity of infestation was varied between rodent host sexes, wherein females had the highest rate of parasitic infestation, and the parasitic index of appearance was very high for one group of parasites (i.e., ticks). The parasitic prevalence was 42.13 % on rodents, and mites were the most prevalent parasite species. Overall, this study was carried out to establish baseline data for ectoparasite-infested rodents in Hail region, Saudi Arabia, and may help for appropriate planning to control zoonotic diseases in this area.

Methods: Medical residents involved in training programs in the western region of Saudi Arabia, including Jeddah, Makah, Medinah, and Taif, were invited to participate in a cross-sectional, anonymous, online survey regarding DNR orders. The 16-question survey was distributed to residents in all training programs in the region using surveymonkey.com, and the results were collected and tabulated. Results: Of 364 residents, 157 completed the questionnaire, resulting in a 43% response rate. The study showed that most (66% internal medicine residents in the western region of Saudi Arabia participate in DNR discussions with patients and family or surrogate decision-makers. In addition, 43% were observed by faculty members, and half of them (51.9% reported feeling comfortable during these discussions. Furthermore, most residents believed that additional educational programs would enhance their competence in addressing issues related to DNR discussions. Conclusion: This study highlights the need for a structured curriculum to teach skills relating to end-of-life issues such as DNR orders to residents in the Saudi Arabian medical system. The majority of residents surveyed believe they would benefit from additional training in DNR discussions. Therefore, an evidence-based curriculum providing instruction for improving discussions regarding DNR orders would improve physician confidence and effectiveness in caring for critically ill patients.

    Full Text Available Background. Khat chewing is highly prevalent in Africa, Yemen and Jazan region, southwest of Saudi Arabia. Most of Jazani Khat chewers consider khat session as a social activity and do not consider khat dependency. The aim of this study was to explore khat dependency and its relationship with the psychophysical symptoms among chewers. Methods. Cross-sectional study on seventy Saudi male khat chewers living in Jazan area. Psychological dependence to khat chewing was evaluated using the Severity of Dependency Scale (SDS. The participants filled in a self-administrated assisted structured questionnaire designed to collect data about their medical history, neurological symptoms, and their chewing behavior. Results. Half (52.2% of khat chewers showed psychological dependency. Those having longer khat sessions (≥6 hours were more liable for dependency. Physical and psychological symptoms were more prevalent among khat dependent chewers. Conclusions. khat has a psychological dependence effect that can be measured by the SDS, even in low doses and with irregular use. SDS scale is a useful tool to expect the burden of either physical or psychological symptoms on khat chewers.

Forty-six patients fulfilling the American College of Rheumatology 1997 criteria (ACR) were collected over a period from January 2004 to December 2008. The results showed an average age of onset of 26.17 (±9.17). The most common clinical features were nonspecific constitutional symptoms (fever, fatigue and malaise) seen in 44 patients (95.7%). Musculoskeletal features seen were mostly arthralgias (91.3%) and arthritis (76.1%). Nephritis was seen in 58.7% and hypertension in 52.2%. Mucocutaneous involvement included oral ulcers (71.7%), hair loss (65.2%), butterfly rashes (67.4%), photosensitivity (47.8%) and discoid lupus (13%). Neurologic manifestations showed psychosis in 17.4%, depression in 15.2% and headache in 28.3%. The most common hematologic presentation was leukopenia (58.7%) followed by hemolytic anemia and anemia of chronic disease (47.8%). Antinuclear antibodies were positive in 44 (95.7%), anti-dsDNA in 38 (42.6%), anti-Ro SSA and La SSB in 38 (82.6%). Anticardiolipin antibodies and lupus anticoagulant were positive in eight (17.4%). Low complement levels (C3 and C4) were seen in 41 (89.1%) of the patients with active disease. The drugs used in treatment were NSAIDs (100%), antimalarials (97.8%), steroids (100%), intermittent cyclophosphamide and other immunosuppressive drugs (71.7%). We found that the age of onset and sex distributions were different from other areas of Saudi Arabia, while clinical manifestations were the same as in other areas. The prognosis of lupus was good overall despite the multi-organ involvement. However, further studies based on larger number of patients are needed.

    Current investigations of the motions of the Arabian and its neighboring plates are primarily based on GPS measurements obtained in the surrounding areas of the Arabian plate, with few stations actually located on the Arabian plate itself in the Kingdom of Saudi Arabia. In order to advance the knowledge of the dynamics of the Arabian plate and its intra-plate deformations, the General Directorate of Military Survey (GDMS), through a collaboration with the Institute of Engineering Surveying and Space Geodesy (IESSG), densified the GPS network in Saudi Arabia, covering nearly two thirds of the tectonic plate. Since July 2002, a network of 32 GPS stations has been established at locations of the Saudi Arabia geodetic network. At all of these GPS stations a concrete pillar has been used as the monument and the locations have been selected in order to give the broadest distribution of observing sites. During 2005, 27 additional GPS stations in the Hejaz and Asser Mountains in the south-western part of Saudi Arabia, have been established, with the GDMS GPS network now comprising a total of 59 stations. In this presentation we will introduce the new GPS network in Saudi Arabia established by GDMS and will present the initial results from campaigns in March 2003 and March 2005. We show preliminary estimates of absolute and relative Arabian plate motions inferred from the GPS network and a detailed comparison of the results based on the Bernese GPS software versions 4.2 and 5.0.

    Full Text Available BACKGROUND: Proper structural foundations for asthma care at primary health care centers [PHCCs], are of essential importance, regarding its management. OBJECTIVE: To assess the adherence of PHCCs to the recommended structural foundation for asthma care. MATERIALS AND METHODS: 35 PHCCs were selected in a cluster random fashion. A questionnaire for structural standards was designed, based on the Saudi national protocol for the management of asthma (SNPMA. A physician and a nurse, each from PHCC, were trained for data collection. Structural facilities deficiency was arbitrarily classified into: least deficient (>75%, moderate to severe deficient (25-75% and most deficient (< 25%. RESULTS: The total population registered, was 131190 [urban: 85701 (65.4%, rural: 45489 (34.6%]. Total registered asthmatics was 4093 [urban: 2585 (63.1%, rural: 1508 (36.9%]. The asthma prevalence rate did not differ significantly between urban (3% and rural (3.3% areas . Structural facilities distribution for asthma care, did not significantly vary among urban and rural PHCCs and none of them fulfilled 100% of the desired standards. The least deficient, were the availability of asthma register and salbutamol, in its various forms. The moderately to severely deficient were the SNPMA, peak flow meter (PFM, nebulizer system, Theophylline and systemic corticosteroid. However, they were most deficient in trained doctors and nurses, record charts for Peak flow meter, spacer, educational material and inhalers of corticosteroid or cromoglycate. CONCLUSION: Proper structural foundations for asthma care at PHCCs, at AL-Qassim region, were below the desired national standards. They were most deficient in trained doctors and nurses, record charts for PFM, spacers, educational material and anti-inflammatory inhalers. Future health directorate strategies have to provide such beneficial interventions for proper asthma care.

    Full Text Available Background/Aims: Despite the remarkable increase in the incidence of Crohn′s disease among Saudis in recent years, data about Crohn′s disease in Saudi Arabia are scarce. The aim of this study was to determine the clinical epidemiology and phenotypic characteristics of Crohn′s disease in the central region of Saudi Arabia. Patients and Methods: A data registry, Inflammatory Bowel Disease Information System (IBDIS, was used to register Crohn′s disease patients who presented to the gastroenterology clinics in four tertiary care centers in Riyadh, Saudi Arabia between September 2009 and February 2013. Patients′ characteristics, disease location, behavior, age at diagnosis according to the Montreal classification, course of the disease, and extraintestinal manifestation were recorded. Results: Among 497 patients with Crohn′s disease, 59% were males with a mean age at diagnosis of 25 years [95% Confidence Interval (CI: 24-26, range 5-75 years]. The mean duration from the time of complaint to the day of the diagnosis was 11 months, and the mean duration of the disease from diagnosis to the day of entry to the registry was 40 months. Seventy-seven percent of our patients were aged 17-40 years at diagnosis, 16.8% were ≤16 years of age, and 6.6% were >40 years of age. According to the Montreal classification of disease location, 48.8% of patients had ileocolonic involvement, 43.5% had limited disease to the terminal ileum or cecum, 7.7% had isolated colonic involvement, and 16% had an upper gastrointestinal involvement. Forty-two percent of our patients had a non-stricturing, non-penetrating behavior, while 32.8% had stricturing disease and 25.4% had penetrating disease. Conclusion: Crohn′s disease is frequently encountered in Saudi Arabia. The majority of patients are young people with a predilection for males, while its behavior resembled that of western societies in terms of age of onset, location, and behavior.

    Two large chemical explosions were detonated in the Dead Sea in order to calibrate seismic travel times and improve location accuracy for the International Monitoring System (IMS) to monitor a Comprehensive Nuclear Test-Ban Treaty (CTBT). These explosions provided calibration data for regional seismic networks in the Middle East. In this paper we report analysis of seismic data from these shots as recorded by two seismic networks run by King Saud University (KSU) and King Abdulaziz City for Science and Technology (KACST) in Saudi Arabia. The shots were well observed in the distance range 180-480 km mostly to the south of the Dead Sea in the Gulf of Aqaba region of northwestern Saudi Arabia. An average one-dimensional velocity model for the paths was inferred from the travel times of the regional phases Pn, Pg and Sg. Short-period Sn phases were not observed. The velocity model features a thin crust (crustal thickness 26-30 km) and low velocities (average P-wave velocity 5.8-6.0 km/s), consistent with the extensional tectonics of the region and previous studies.

    Flash flooding, as a result of excessive rainfall in a short period, is considered as one of the worst environmental hazards in arid regions. Areas located in the western provinces of Saudi Arabia have experienced catastrophic floods. Geomorphologic evaluation of hydrographic basins provides necessary information to define basins with flood hazard potential in arid regions, especially where long-term field observations are scarce and limited. Six large basins (from North to South: Yanbu, Rabigh, Khulais, El-Qunfza, Baish and Jizan) were selected for this study because they have large surface areas and they encompass high capacity dams at their downstream areas. Geographic Information System (GIS) and remote sensing techniques were applied to conduct detailed morphometric analysis of these basins. The six basins were further divided into 203 sub-basins based on their drainage density. The morphometric parameters of the six basins and their associated 203 sub-basins were calculated to estimate the degree of flood hazard by combining normalized values of these parameters. Thus, potential flood hazard maps were produced from the estimated hazard degree. Furthermore, peak runoff discharge of the six basins and sub-basins were estimated using the Snyder Unit Hydrograph and three empirical models (Nouh’s model, Farquharson’s model and Al-Subai’s model) developed for Saudi Arabia. Additionally, recommendations for flood mitigation plans and water management schemes along these basins were further discussed.

    Full Text Available Background: Saudi Arabia used to be hyperendemic for HBV infection. Most of infection occurs in early life. HBV vaccine was, therefore, introduced in 1989 as the seventh primary immunogen of the EPI Program. This study is conducted to evaluate the efficacy of this program in Riyadh and Hail Regions. Method and Patients: A cohort follow-up study of children from Riyadh and Hail, who had been vaccinated in 1989, evaluated in 1991 and tested for HBV markers six years later. Results: The files of 303 children from Riyadh and Hail, who were investigated in 1991 retrieved and only 119, were available for testing. Fifty percent of the children have still a protective anti-HBs tittre. One vaccinated child was found to be positive for HBsAg. According to this study, the efficacy rate against HBsAg carriage is 88%. Conclusion: This study demonstrates the tremendous effect of HB vaccine on the HBV infection of Saudi children in these two regions

    The levels of four metals (Zn, Cu, Cd, and Pb) were evaluated in two fruit types (apricot and fig), a fruity vegetable (tomato), and three leafy vegetables (arugula, spinach, and lettuce) that are commonly grown and consumed in Aseer Region, Saudi Arabia. Flame atomic absorption spectrophotometry was employed for quantification. The quality of results was checked by a certified reference material (NIST SRM 1570a). Good recovery values in the range of 87-104% were achieved. Metals were quantified in washed and unwashed samples to evaluate the effect of washing. Statistically, no significant difference was noticed (p>0.05), except for Zn in arugula and Cu in apricot and spinach. The levels of metals found in the analyzed fruits and vegetables were in their normal ranges in crops and not posing any serious risks to the consumers in Aseer Region. The toxic elements Pb and Cd were well below the maximum levels set in the Saudi and international food standards. Zn and Cu levels were comparable to the ranges reported in worldwide previous studies.

    Full Text Available To determine the pattern of lower gastrointestinal disease in the Eastern region of Saudi Arabia we analysed 1907 colorectal biopsies obtained from 1590 consecutive patients (1256 males &334 females, evaluated during a 13 year period (1983-1996 in a tertiary care teaching hospital. The age range was 6-81 years with a mean of 37 + 15. During the same period 6874 new patients were seen in the Gastroenterology Clinics. Saudi Arabs constituted 970 (61 % of all patients. The remaining 620 (39% were non-Saudi, mostly of Arab origin from neighbouring countries. The most common presenting symptom for referral was abdominal pain (1193 patients, 75% followed by diarrhea (636 patients, 40%. The most frequent histologic diagnosis was a normal mucosa followed by non specific proctocolitis accounting respectively for 37.9% and 37.4% of all cases. These were followed by schistosomiasis, 113 (7.1%, adenocarcinoma, 91 (5.7% and ulcerative colitis, 91 cases with a relative frequency of 5.7% and a calculated prevalence of 1.3%. Of significance was the encounter of 14 cases of Crohn′s disease amounting to 0.9% of all cases with a calculated prevalence of 0.2%. A minority of 83 patients (5.2% were cases of either a benign polyp, diverticular disease, tuberculosis, ischaemia, lymphoma, pseudomembranous colitis (PMC, eosinophilic gastroenteritis or malacoplakia. These data show that although a "normal mucosa" and "nonspecific proctocolitis" were the dominant diagnoses, significantly, ulcerative colitis and Crohn′s disease exist and should be considered in the differential diagnosis of lower GI disease.

    Full Text Available To determine the presence of rubella immunity among pregnant women attending their first prenatal visit in Jeddah, Saudi Arabia, a retrospective, descriptive, cross-sectional, hospital-based study (prevalence study was undertaken. A total of 10276 women attending prenatal clinics between January 1, 2008, and December 31, 2011 were included. Rubella screening tests (immunoglobulins: IgG and IgM, rubella antibody titer levels, patient age, gravidity, parity, and the number of previous abortions were analyzed. No patients tested IgM positive, and 9410 (91.6% were immune (IgG positive; the remaining 866 (8.4% were susceptible. There were no significant differences in gravidity, parity, or the number of previous abortions between immune and nonimmune groups. In contrast, the immunity rate decreased with increasing age, with a significant difference between the youngest age group (15–19 years and the oldest age group (40–49 years (P=0.0005; odds ratio, 2.86; 95% confidence interval, 1.7–4.7. Rubella immunity among pregnant women was high (91.6% but decreased significantly with increasing age. A possible explanation for this is the change in the rubella vaccination policy in Saudi Arabia in 2002, from 1 dose to 2 doses. In addition, antibody levels begin to decline after vaccination and natural infection.

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

    Full Text Available Knowledge of Land Use and Land Cover (LULC changes is important for many planning and management activities. It is thought to be an essential element for modeling and understanding the major land forms, especially in arid regions like Saudi Arabia. This study investigates the LULC changes in Dirab region of Saudi Arabia between 1980 and 2010, using Landsat TM/ETM+images. After the geometric correction and radiometric normalization, multi-temporal image data sets were spectrally enhanced separately using Principal Component Analysis (PCA and Tasseled Cap Transformation (TCT. Each image was then separately subjected to supervised classification and processed to identify and quantify LULC changes (vegetation, barren land and built-up area. Post Classification Comparison (PCC method was adopted for LULC change detection. Change trajectories (“from-to” classes and accuracy assessments were made by comparing the detected land use change layers with medium/high resolution images of Google Earth data base. The TCT enhanced procedure gave better identification of the changed areas than PCA based method. The overall accuracy of PCA based change detection was 64.58, 62.68 and 62.12% for 1980-1990, 1990-2000 and 2000-2010 images, respectively. However, the TCT based change detection resulted in higher accuracy of 77.78, 75.62 and 77.92% for 1980-1990, 1990-2000 and 2009-2010, respectively. The results suggested that significant land use changes occurred in Dirab area from 1980 to 2010, which may be related to rapid development of agriculture between 1980 and 2000 and economic development and urban expansion between 2000 and 2010. It was further noted that most changes occurred in cropland areas due to urban encroachment.

    Full Text Available Asir Region in the southwest of Saudi Arabia has been a subject for expansion of agricultural projects, urbanization, which presumably have impact on distribution of phlebotomine sandflies. Few reports are available on sandflies in this region which is an important focus of cutaneous leishmaniasis. Therefore, this study aimed at updating the species composition, distribution and periodical fluctuation of sandflies in this region. Specimens were monthly collected by the Center for Disease Control light traps for one year in four localities representing different altitudes. In five other, collections were twice during the year period. Ten species (six Phlebotomus and four Sergentomyia were identified, of which P. arabicus (32% was the most common followed by P. bergeroti (29% and P. sergenti (15%. Of the reported species, S. palestinensis is considered a new record from Asir. Sandflies were more common and maximum biodiversity was observed in lowlands and not in high altitudes. At different altitudes, the two commonest species were more active during spring. Sandfly density (sandfly/trap was directly related to temperature and inversely related to altitude, relative humidity (RH and wind velocity (P<0.05. To sum up, the distribution and abundance of sandflies in Asir are influenced by a combination of different factors: temperature, RH, wind velocity and altitude.

    Unexpected flash flooding is one of the periodic hydrological problems affecting the city of Tabuk in Saudi Arabia. The region has high potential for floods as it suffers high rainfall intensity in a short time and also has high urbanization rates and topographic complexity. Constructing flood prevention dams is one option to solve this problem. A cost-effective design requires a detailed feasibility study and analysis for the selection of suitable sites. The aim of this study was to develop a method for selecting a suitable site for flood protection dams in the Abu Saba'a district, the most affected part of the city of Tabuk during the flash flood in January 2013. Spatial analysis was applied using Landsat Thematic Mapper images and Shuttle Radar Topography Mission digital elevation model to select a site in the Abu Saba'a area. A simple model using ArcGIS was built including all suggested parameters. The results showed the best site for a dam was 2 km distance backfrom the area, where all parameter values matched. The results showed that the dynamic properties of land cover can affect site selection. It is therefore suggested that more field and hydrological data should be gathered for greater accuracy.

    Hemorheology, a measure of rheological properties of blood, is often correlated with cerebral blood flow and cardiac output; an increased blood viscosity may increase the risk of thrombosis or thromboembolic events. Previous studies have reported a large variation in hemorheological properties of blood among smokers. This prompted us to conduct coagulation experiments to evaluate the effect of cigarette smoking on hematological parameters, like cell counts, and coagulation parameters among young males in Al-Jouf region, Saudi Arabia. The hematological and coagulation parameters were used to relate the changes in viscosity and coagulation to smoking. A total of 321 male participants (126 nonsmokers and 195 smokers) were enrolled into the study as randomized sample. Complete blood count was measured by hematology analyzer, and coagulation tests were performed by coagulation analyzer. Thettest analysis was performed to compare the relationships of variables between the 2 groups. The results confirmed that smoking alters some hematology parameters leading to significant deterioration in blood flow properties. Smoking also increased the hematocrit (HCT), whole blood viscosity (WBV), and plasma viscosity (PV) but decreased the international normalized ratio (INR). The decrease in INR was found to be associated with the increase in WBV, PV, and HCT. Further investigations are necessary to assess the reversibility of such changes in cessation of smoking or other elements of influence.

    The region of Asir is located in the southwestern part of the Kingdom of Saudi Arabia between longitudes 41 - 45 E and latitudes 17 - 21 N. Known for its natural beauty and cool climate delight the visitors and the region has become a destination for tourists. One of the main problems in the Asir region is the high demand for water during tourism seasons especially in view of the rapidly growing tourism sector. Flourishing tourism in the region is challenged by the scarcity of water resources and there is urgent need to identify alternative sources of potable water. It is found that fog water collection is a viable resource and Asir region is the most suitable location for fog water harvesting. An operational fog water collection project was initiated in 2007 to provide fresh water supply. Al-Sooda, situated at an altitude of about 3,000 m, was identified as the most suitable experimental site and two large fog collectors measuring 20 m by 2 m each were erected in 2009. The distance between the two sites is about 2 km. This paper gives the methods used to select the experimental site and the design of the large fog collection system. The fog collectors are flat rectangular nets supported by a post at both ends and arranged perpendicular to the direction of the prevailing wind. The collection surface, comprising two layers of black polypropylene mesh net, is fastened laterally to the posts with a set of fastening bars. The aluminum trough located below the mesh net catches the water that runs down the net and carries it to a pipe connected to the storage tank. Because the fog collectors are long and require space for guy wires for the posts, the basic site consideration is that at least 25 m of horizontal land available for the erection. Meteorological instruments and the portable weather station are used to measure the climatic data which are recorded three times a day, namely at 7:00, 14:00 and 19:00 h.

    This study was conducted in the Assir region of southwestern Saudi Arabia to compare the activities of honeybee colonies of indigenous Apis mellifera jemenitica (AMJ) and imported Apis mellifera carnica (AMC) during the late summer and autumn of 2009 and 2010. The results showed that the workers of the two races exhibited relatively similar forage timings throughout the period of study (August-November). The highest numbers of foraged workers were recorded at 6:00 am, 10:00 am and 6:00 pm, while the lowest numbers were recorded at 8:00 am, 12:00 pm and 4:00 pm. Although foraging activity was negatively affected by decreased temperature, AMJ was more resistant to cold than AMC. In the first season, the smallest amount of worker brood rearing was recorded in August, and the highest amount of rearing occurred in November in both races. In the second season, the smallest amount of brood was observed in October, and the largest amount of brood was observed in November. Brood rearing and pollen collecting was significantly (P < 0.05) higher in AMJ compared with AMC, while AMC stored significantly (P < 0.05) more honey than AMJ during the tested periods. In AMJ colonies, a positive significant correlation was observed between the area of the sealed worker brood and stored pollen, while a negative but nonsignificant correlation was observed between the area of the sealed worker brood and surplus honey. In the AMC colonies, a positive significant correlation was observed between the area of the sealed brood and the stored pollen and surplus honey.

    Full Text Available Cutaneous leishmaniasis is an annoying and disfiguring disease affecting around 1,500,000 individuals globally. There are endemic pockets of this disease in Taif region. In some patients, lesion often weeps and leads to scar formation. The study was conducted to see the efficacy of fluconazole and itraconazole in the patients of cutaneous leishmaniasis and the effect of these drugs on liver enzymes and kidney markers.Positivity of Leishmania was recorded by microscopic examinations of smears. Specific diagnosis for Leishmania major and L. tropica was made with the help of nested polymerase chain reaction. Fluconazole was given at the rate of 200mg/day while itraconazole was given at 150mg/day for six weeks. AST, ALT, creatinine and urea were estimated during medication.Leishmania major and L. tropica were the species responsible for cutaneous leishmaniasis in Taif region. 81% patients had single lesions, mostly on face followed by hands and legs. 15% of the lesions had bacterial contamination. In terms of efficacy, fluconazole gave slightly better results compared to itraconazole. After 6 weeks of medications, slightly elevated values were recorded for liver enzymes and creatinine.Transmission of leishmaniasis in Taif region is probably because of poor coverage of residual insecticides spraying at hiding places in pile-ups of rocks and abandoned houses from where sand flies visit nearby houses and cattle sheds during night. Fluconazole and itraconazole may be used for the treatment of cutaneous leishmaniasis with good recovery rate and fewer side effects.

    Full Text Available The present study aims to investigate the effect of different social factors on the woodcutting frequency in Tabuk Region. A total of 100 people participated in this study by answering the questionnaire questions. The conservation knowledge of the participants was also assessed through 4 questions (Yes or No. The final score of the conservation knowledge assessment is 4. The present study findings showed that most of people like to cut the wood for heating during winter and fall seasons. The frequency of woodcutting in Tabuk Region was once a month. Among the social factors involved in this study, education showed negative and significant relationship with the number of logging times. However, age had positive relationship with the number of logging times. The most favourbale species to be cut and used for heating and cooking in Tabuk are; Acacia tortilis, Acacia ehrenbergiana, Retama reaetam and Calligonum comosum. For the assessment of the public conservation knowledge, it was found that most of participants had moderate to good conservation knowledge as most of them answered 3 questions correctly out of 4. The conservation knowledge showed to be affected positively by education level and negatively by the number of family members. In conclusion, it was found that there is remarkable woodcutting stress on wild plants in Tabuk Region and immediate and effective actions should be performed

    Full Text Available BACKGROUND: The use of Khat leaves (Catha edulis in Jazan, southwest of KSA, is prevalent among all segments of the population. OBJECTIVE: This study was conducted to assess the prevalence and predictors of Khat chewing among intermediate and secondary school students of Jazan region. METHODOLOGY: A cross-sectional survey was conducted in late 2011 in Jazan region. A random sample of 3923 students was selected from 72 intermediate and upper secondary schools representing the different educational sectors of the region. A structured self-administered questionnaire was used for data collection. Descriptive statistics, a chi-squared test and logistic regression were performed to examine the prevalence, associations and predictors of Khat chewing. RESULT: The overall Khat chewing prevalence among students was 20.5% (95% C.I.: 19.27-21.79. The prevalence was significantly higher among males, at 33.1% (95% CI: 31.16-35.08, than among females 4.3% (95% C.I.: 3.39-5.31 ( P <0.001. Univariate analysis revealed that gender, age, academic performance, friends' smoking and Khat chewing, and students' smoking status were associated with a significantly high risk of Khat chewing ( P <0.001 for all. The multivariate logistic regression analysis suggested that the most important independent predictors of Khat chewing among the students in our sample were students' smoking status (OR = 13.02, P <0.001, friends' use of Khat (OR = 5.65, P <0.001, gender (OR = 4.62, P <0.001, and friend's use of tobacco (OR = 1.43, P <0.001. CONCLUSION: A significant percentage of students chew Khat. The abuse of Khat is significantly associated with gender, peer influence, and cigarette smoking. Intervention programs are needed to create awareness among school students and to reduce the prevalence of the habit and its unfavorable consequences.

    Full Text Available Availability of data on agricultural activities and production are essential for an appropriate socio-economic planning and sustainability. This study was conducted using a questionnaire that was randomly distributed to farmers to identify some features of the agricultural activities in Hail region and to serve as baseline data on agricultural practices. The questionnaire was divided into main topics including socio-economic status of farms, farm area, main crops, production systems, agricultural practices, financial support, and use of wind breaks, water conservation, animal husbandry and marketing. Some of the results showed that date palms and alfalfa fodder were found to be the main grown crops in addition to citrus, grapes, vegetables, wheat and Rye. In most cases, all these crops were cultivated in open fields, compared to only 18% grown in green houses. About half of the farmers adopted the monoculture system and only 44.9% of them applied the crop rotation. More than 70% of farmers raise animals and the most commonly reared animal are sheep (53.6% followed by goats (23%, camels (18% and poultry (4.5%. The study revealed that Hail region is an important agricultural area in KSA and some agricultural practices need to be revised and directed towards sustainability through extension programmes.

    We propose a framework for spatially estimating a proxy for coral reef resilience using remote sensing. Data spanning large areas of coral reef habitat were obtained using the commercial QuickBird satellite, and freely available imagery (NASA, Google Earth). Principles of coral reef ecology, field observation, and remote observations, were combined to devise mapped indices. These capture important and accessible components of coral reef resilience. Indices are divided between factors known to stress corals, and factors incorporating properties of the reef landscape that resist stress or promote coral growth. The first-basis for a remote sensed resilience index (RSRI), an estimate of expected reef resilience, is proposed. Developed for the Red Sea, the framework of our analysis is flexible and with minimal adaptation, could be extended to other reef regions. We aim to stimulate discussion as to use of remote sensing to do more than simply deliver habitat maps of coral reefs.

  14. Saudi Arabia.

    1986-12-01

    In 1985, Saudi Arabia's population stood at 9.6 million, with an annual growth rate of 2.8%. The infant mortality rate was 78/1000 and life expectancy was 60 years. Literacy was at the 50% level among men and 25% among women. Of the work force of 3 million, 66% are foreign workers. The labor force is distributed as follows: agriculture, 14%; industry, 11%; services, commerce, and government, 53%; construction, 20%; and oil and mining, 2%. The GDP was US$98.1 billion in 1985-86, with an annual growth rate of 8% and a per capita GDP of $9800. Under the impact of rapid economic growth, urbanization has advanced rapidly and 95% of the population is now settled. Saudi Arabia, a monarchy, is divided into 14 provinces that are governed by princes or relatives of the royal family. Oil is the major source of foreign exchange, contributing 81% of government revenues. Ample government funds and foreign exchange resources are available for development, defense, and aid to other Arab and Islamic countries. The government has sought to allocate its petroleum income to transform its relatively undeveloped oil-based economy into that of a modern industrial state while maintaining traditional Islamic values. The standard of living of most Saudis has improved significantly. A shortage of skilled workers at all levels remains the principal obstacle to rapid development.

    Full Text Available Although there has been significant progress in the management of hypertension, rates for control of this chronic disease in the Kingdom of Saudi Arabia (KSA has been shown to be very low. This study was aimed to assess the knowledge of primary health care (PHC physicians and the extent of their adherence to the recommendations of clinical practice guidelines concerning care of hypertensive patients. The assessment was made in the Aseer region of KSA using a modified version of the World Health Organization "Physician Inquiry Questionnaire." Only 5.6% of the participants measured blood pressure (BP with the patient in sitting and other postures. Variable sphygmomanometer cuff sizes for different patients were used by 56.5% of the participants, while 74.8% correctly recorded the diastolic BP at Koratkoff sound, phase- 5. Among non- diabetics, the correct diagnosis of systolic and diastolic hypertension was reported by 76.7% and 81.4% respectively, of the PHC physicians. Among diabetics, the correct diagnosis of systolic and diastolic hypertension was reported by 36% and 17.1% of the PHC physicians, respectively. Most physicians inquired about cardiovascular risk factors. Several important items of patients′ clinical examination were not completely covered by physicians, e.g., fundus examination (75.2%. PHC physicians missed a few investigations and laboratory tests, e.g., ECG (87.9%, serum creatinine (88.2% and lipid profile (89.8%. Less than one- fifth of the physicians correctly chose the thiazide diuretics as the preferred initial anti- hypertensive agent (19.9%. Almost two- thirds of the physicians (65.2% emphasized the importance of BP self- measurement, 89.8% encouraged patients to use a reminder system while 96.3% motivated patients for BP control. Measures for lifestyle modification included weight reduction (98.8%, sodium restriction (97.5%, physical exercise (96.3% and behavioral improvement (87.6%. Our study suggests that continuing

    Objective: To evaluate the medicinal uses of Rhanterium epapposum Oliv. (R. epapposum) growing in northern border region of Saudi Arabia, through the chemical diversity of essential oils extracted from its flowers, leaves and stems. Methods: Aerial parts of R. epapposum were collected in April 2014. Air dried flowers, leaves, and stems were separately subjected to hydrodistillation in a Clevenger-type apparatus for 4 h to extract the essential oils. Gas chromatography-mass spectrometry analysis of the essential oils was carried out using an Agilent 6890 gas chromatograph equipped with an Agilent 5973 mass spectrometric detector. Results: A total of 51 compounds representing 76.35%–94.86%of flowers, leaves and stems oils composition were identified. The chemical profiles of the studied fractions revealed the dominance of monoterpenes, regardless of qualitative and quantitative dif-ferences observed. Limonene, linalool, 4-terpineol and a-cadinol represented the major constituents of flowers oil. Leaves oil was dominated by limonene, sabinene, a-pinene and β-myrcene whereas linalool, ionole, a-cadinol, β-eudesmol, 4-terpineol, and a-terpineol were the major constituents of stems oil. Conclusions: Essential oils from flowers, leaves and stems of R. epapposum growing in northern border region of Saudi Arabia are considered as a rich source of monoterpenes which have biological activities.

  18. First dinosaurs from Saudi Arabia.

    Directory of Open Access Journals (Sweden)

    Benjamin P Kear

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

    Background and Objectives. β-Thalassemia and sickle cell disease are genetic disorders characterized by reduced and abnormal β-globin chain production, respectively. The elevation of fetal hemoglobin (HbF) can ameliorate the severity of these disorders. In sickle cell disease patients, the HbF level elevation is associated with three quantitative trait loci (QTLs), BCL11A, HBG2 promoter, and HBS1L-MYB intergenic region. This study elucidates the existence of the variants in these three QTLs to determine their association with HbF levels of transfusion-dependent Saudi β-thalassemia patients. Materials and Methods. A total of 174 transfusion-dependent β-thalassemia patients and 164 healthy controls from Eastern Province of Saudi Arabia were genotyped for fourteen single nucleotide polymorphisms (SNPs) from the three QTL regions using TaqMan assay on real-time PCR. Results. Genotype analysis revealed that six alleles of HBS1L-MYB QTL (rs9376090C p = 0.0009, rs9399137C p = 0.008, rs4895441G p = 0.004, rs9389269C p = 0.008, rs9402686A p = 0.008, and rs9494142C p = 0.002) were predominantly associated with β-thalassemia. In addition, haplotype analysis revealed that haplotypes of HBS1L-MYB (GCCGCAC p = 0.022) and HBG2 (GTT p = 0.009) were also predominantly associated with β-thalassemia. Furthermore, the HBS1L-MYB region also exhibited association with the high HbF cohort. Conclusion. The stimulation of HbF gene expression may provide alternative therapies for the amelioration of the disease severity of β-thalassemia. PMID:28280727

    This study presents the level of organochlorine pesticide (OC) residues in human milk samples collected from donor mothers aged from 18 to 30 years old, from four cities in Eastern district of Saudi Arabia (Al-Hassa, Al- Khobar, Al-Jubail, and Al-Dammam). Pesticides residues were extracted from the samples and analyzed using GC-MS. The results showed that, only pp'DDE and p,pDDD, were found in 82.5% and 70% of analyzed samples respectively, the total DDT were at level of 0.37, 0.32, 0.30 and 0.46 μg/L in the four cities respectively and were far below the MRL of 50 μg/L (FAO/WHO). The estimated daily intake (EDI) of DDT ingested by infant weight 3.5 kg ranged between 0.06 and 0.10 μg/kg, which is less than the ADI issued by (EFSA, 2014). Lindane (γ-HCH) found in 91.25% of the analyzed samples at level of 0.37, 0.35, 0.35 and 0.29 μg/L. The EDIs of Lindane by infant were far below the ADI of 5 μg/kg bw/day. Dieldrin and Enderin were found in 27.5% and 58.8% of samples respectively and were lower than MRL issued by FAO/WHO, but the (EDI) was higher than the ADI issued by EFSA. The isomer A-heptachlor was detected in 51% of the samples, at levels were 15 times lower than the MRL issued by FAO/WHO, but EDIs by infants were 2-4 times higher than the ADI issued by EFSA. However, the results of the four studied areas in Saudi Arabia showed no statistically different among locations (p > 0.05).

    Wastewater irrigated fields can cause potential contamination with heavy metals to soil and groundwater, thus pose a threat to human beings . The current study was designed to investigate the potential human health risks associated with the consumption of okra vegetable crop contaminated with toxic heavy metals. The crop was grown on a soil irrigated with treated wastewater in the western region of Saudi Arabia during 2010 and 2011. The monitored heavy metals included Cd, Cr, Cu, Pb and Zn for their bioaccumulation factors to provide baseline data regarding environmental safety and the suitability of sewage irrigation in the future. The pollution load index (PLI), enrichment factor (EF) and contamination factor (CF) of these metals were calculated. The pollution load index of the studied soils indicated their level of metal contamination. The concentrations of Ni, Pb, Cd and Cr in the edible portions were above the safe limit in 90%, 28%, 83% and 63% of the samples, respectively. The heavy metals in the edible portions were as follows: Cr > Zn > Ni > Cd > Mn > Pb > Cu > Fe. The Health Risk Index (HRI) was >1 indicating a potential health risk. The EF values designated an enhanced bio-contamination compared to other reports from Saudi Arabia and other countries around the world. The results indicated a potential pathway of human exposure to slow poisoning by heavy metals due to the indirect utilization of vegetables grown on heavy metal-contaminated soil that was irrigated by contaminated water sources. The okra tested was not safe for human use, especially for direct consumption by human beings. The irrigation source was identified as the source of the soil pollution in this study.

    Hail region of Saudi Arabia (KSA) has the highest adult obesity rates in the entire kingdom and limited information is available about the prevalence and patterns of growth markers. Therefore, it is important to monitor the growth trends to implement effective public health preventive strategies for the region. This study aims to estimate the prevalence of growth profile patterns (stunting, wasting, underweight, and overweight) and its associations with nutrient intake and dietary patterns among children and adolescents. A cross-sectional survey was conducted involving 1420 children and adolescents (2-18 years), selected using a multistage stratified random-sampling technique representing both female and male schools from Hail region, KSA. Growth profile z-scores were generated using 2006 and 2007 WHO growth standards. The overall prevalence of 4.73% moderate and 1.54% severe underweight; 6.65% moderate and 2.59% severe stunting; 6.34% moderate and 2.55% severe wasting was present in the study population. Stunting decreased as age progressed with concurrent increase in the prevalence of overweight and obesity. There was a significantly higher prevalence of overweight (18.55% versus 23.05%; P < 0.001) and obesity (8.7% versus 13.85%; P < 0.001) in adolescents than in school-age children with higher prevalence in females as compared to males. Both stunted and overweight/obesity groups had significantly lower mean intakes for critical micronutrients necessary for growth as compared to normal children.

    Full Text Available The chemical components of essential oils derived from leaves and flowers of Lantana camara growing in Saudi Arabia are analyzed for the first time using gas chromatography techniques (GC–MS, GC–FID, Co-GC, LRI determination, and database and literature searches on two different stationary phase columns (polar and nonpolar. This analysis led to the identification of total 163 compounds from leaves and flowers oils. 134 compounds were identified in the oil obtained from leaves of L. camara, whereas 127 compounds were identified in the oil obtained from flowers; these compounds account for 96.3% and 95.3% of the oil composition, respectively. The major components in the oil from leaves were cis-3-hexen-1-ol (11.3%, 1-octen-3-ol (8.7%, spathulenol (8.6%, caryophyllene oxide (7.5% and 1-hexanol (5.8%. In contrast, the major compounds in the flowers oil were caryophyllene oxide (10.6%, β-caryophyllene (9.7%, spathulenol (8.6%, γ-cadinene (5.6% and trans-β-farnesene (5.0%. To the best of our knowledge, cis-3-hexen-1-ol and 1-octen-3-ol that were identified as major components in this study have not been reported earlier from Lantana oils.

    In countries with absolute water scarcity such as the Kingdom of Saudi Arabia (KSA), large-scale actual evapotranspiration estimation is of great concern in water use practices. Herein, spatial and temporal distribution of actual evapotranspiration (AET) in the western and southern regions of KSA during 1992-2014 was estimated using the SEBAL model with field observations. Zonal statistics for each land use-cover type were also identified, in order to understand their effects on water consumption. In addition, daily and seasonal water consumption for major crops was computed. Results revealed a gradual increase in monthly AET values from January to April and subsequent decline from May to December. The maximum monthly AET values were observed for irrigated cropland in southwestern, central, and southeastern regions of Asir Province, central and southwestern regions of Al-Baha Province, central and the plains region of Jazan Province, southern portion of Makkah Province, and limited areas in the northern regions of Madinah Province. The annual AET ranged from 418.8 to 3442.3 mm yr-1. The normal distribution of mean annual AET values ranged from 717 to 1020 mm yr-1. Forty-two percent of the study area had an annual AET that ranged from 717 to 1020 mm yr-1. The second highest range of frequencies was concentrated around 1020-1322 mm yr-1, representing the majority of agricultural land. The consumptive water use of the different land cover types in study area indicated that irrigated cropland which occupied 14.6% of the study area had AET rates much higher than other land uses. Water bodies are the next highest, with forest and shrubland and sparse vegetation slightly lower, and very low AET rates from bare soil. Daily and seasonal water consumption of major cropping systems varied spatially depending on cropping practices and climatic conditions.

    This study was performed to determine the levels of eight heavy metals in irrigation well water and soil and to assess the suitability of some leafy green plants that are commonly cultivated in the Al-Kharj region, Saudi Arabia, for human consumption using an atomic absorption spectrometer. The mean concentrations of metals ranged from 0.0001 to 0.436 mg/L in well water and from 0.248 to 164.52 mg/kg in soil. The heavy metal concentrations showed significant differences among the different leafy green plants studied. Parsley (4.98 mg/kg) exhibited higher levels of Pb than other leafy green plants, whereas mallow (0.097 mg/kg) revealed greater amounts of Cd than other plants. All of the leafy green plants retained essential metals (Cu, Zn, Fe and Mn) more than the toxic metals (Pb and Cd). The levels of some of the metals in the leafy green plants were found to meet the FAO/WHO-recommended limits. The monitoring of heavy metals in leafy green plants must be continued because these plants are the main source of food for humans in many parts of the world and are considered to be bio-indicators for environmental pollution.

    Saudi Arabia is an arid and the largest country in the middle east with a total land area of 2.253 x 10(6) km2. Recent urban and rural expansion has shown manifold increases in water use in various sectors. Water resources are limited and non-renewable coupled with unpredicted scanty rainfall. In order to meet the rising water needs, evaluation of water quality is important for allocation to various uses. A total of 101 well water samples were collected from Al-Ahsa Oasis. Water samples were analyzed for total salt concentration, pH, Ca, Mg, Na, K, HCO3, Cl, SO4, NO3, F and B contents. Soil Salinity Development (SSD), adjusted sodium adsorption ratio (adj.SAR), adjusted sodium adsorption ratio (adj. R(Na)) and Exchangeable Sodium Percentage (ESP) were calculated. The EC of groundwater ranged between 1.23 and 5.05 dS m(-1). Sodium was the most abundant cation followed by Ca, Mg and K in descending order. Chloride was the most abundant anion followed by SO4 and HCO3 in groundwater of Al-Ahsa Oasis. A significant correlation was found between Na and Cl (R2 = 0.936). Thermodynamics calculation revealed that an appreciable amount of Ca and Mg is associated with Cl and SO4 ions. The SAR and ESP values are within the permissible limits according to Ayers and Westcot, 1985. The NO3 concentration is within safe limits for drinking purpose according to WHO (1998) standards. The Saturation Indices (SI) indicated that groundwater is under-saturated (negative SI) with respect to certain minerals (for example: calcite, dolomite, gypsum, anhydrite, halite, pyrite, fluorite and aragonite) and oversaturated (positive SI) with respect to some other minerals (For example: Goethite, Siderite and hematite). The negative saturation index (SI) reveals that most of minerals are in un-saturated state and will dissolve more Ca and Mg into the soil solution after irrigation. A good relationship exists between Cl and other ions (Na, Ca and Mg) as well as between SO4 and Ca and Mg ion of

    Full Text Available Objective: The purpose of this study was to assess the available pediatric pulmonary services, in terms of workforce, resources, and distribution across Saudi Arabia. This would help in proper utilization of resources and direct future planning. Methods: A cross-sectional survey among pediatric pulmonologists registered in the Saudi Thoracic Society. Results: Among 43 practicing pediatric pulmonologist in Saudi Arabia, 29 have responded to the survey (response rate of 67.4%. The majority of practicing pediatric pulmonologists were young graduates with less than 5 years′ experience (44.8% and were North American training programs graduates (69%. The majority of the respondents (51% were located in Riyadh, 27% in Jeddah, 14% in the Eastern region and 3% in Madinah and Al-Majma′a. Most of the respondents had access to basic diagnostic tools required in the subspecialty, a majority of them (85% lack dedicated pediatric pulmonary function laboratories. Nearly, 80% of the hospitals performed less than 50 flexible bronchoscopies/year. Conclusion: Pediatric pulmonology is a growing subspecialty in Saudi Arabia with well-trained and experienced physicians. Our study represents an overview of the available pediatric pulmonology services in Saudi Arabia, which would help in future planning and better utilization of the available resources.

    2011-08-01

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

    2016-01-01

    Full Text Available Objective: This exploratory study sought to measure current self-reported experiences of older Saudi adults. Method: Self-reported aging perceptions and demographic data from semistructured questions were obtained from 52 community-dwelling older Saudi adults aged 50 or older. A thematic content analysis was completed around issues of family life/social support, daily/weekly activities, health and health programs, and older adults’ own thoughts about aging and the experience and future of personal aging. Results: Several key themes emerged from the interviews. The majority of respondents in this preliminary study acknowledge a preference for family care. Formal programs in Saudi Arabia are attended with relative infrequency while older adults recognize family support as the preferred method of support. Older Saudi interviewees hold a positive view of aging, but physical functioning, varying financial resources, and other daily obligations are a concern for those in this study. Discussion: Data suggest as the Saudi population ages, more research is needed on the aging experience with particiular emphasis on issues relevant to older adults . Future research must work to clarify the aging experience as cultural context changes.

The General Administration of Mental Health and Social Services of the Ministry of Health over the past 4 years has sought to streamline the delivery of mental health care services to health consumers in Saudi Arabia. Objective: We overview here the outcome of a survey that assessed the Saudi MHS and suggest strategic steps for its further improvement. Method: The World Health Organization Assessment Instrument for Mental Health Systems was used systematically to collect information on the Saudi MHS in 2009–2010, 4 years after a baseline assessment. Results: Several mental health care milestones, especially provision of inpatient mental health services supported by a ratified Mental Health Act, were achieved during this period. However, community mental health care services are needed to match international trends evident in developed countries. Similarly, a larger well-trained mental health workforce is needed at all levels to meet the ever-increasing demand of Saudi society. Conclusion: This updated MHS information, discussed in light of international data, will help guide further development of the MHS in Saudi Arabia in the future, and other countries in the Eastern Mediterranean region may also benefit from Saudi experience.

    Background Diabetic nephropathy (DN) is a chronic microangiopathic complication of type 2 diabetes mellitus (DM).Vascular endothelial dysfunction resulting from impaired nitric oxide synthase (NOS) activity in the vascular endothelial cells has been suggested as playing an important role in the pathogenesis of diabetic nephropathy (DN). Endothelial nitric oxide synthase (E-NOS) gene G894T polymorphism has been reported to be associated with endothelial dysfunction leading to DN. Our objective was to evaluate the association of G894T polymorphism of eNOS gene with the risk of DN among type 2 diabetic Saudi patients. Methods One hundred and twenty subjects were included in this study. They were divided into three groups. Group I, 40 controls. Group II, 40 type 2 diabetic patients without nephropathy. Group III, 40 type2 diabetic patients with nephropathy. Endothelial nitric oxide synthase (eNOS) G894Tpolymorphism was detected by polymerase chain reaction–restriction fragment length polymorphism (PCR–RFLP). Plasma nitric oxide (NO) levels were estimated. Results E-NOS genotype frequency showed non-significant differences among the all studied groups (p > 0.05). Both diabetic groups had significantly higher plasma nitrate levels than in controls with a significant increase in group III than in group II patients (all p diabetic Saudi patients. The higher plasma levels of nitrates as a marker of oxidative stress in diabetic patients with nephropathy suggest the possible role of oxidative stress but not e-NOS gene SNP in pathogenesis of the DN.

    Skin cancer is the ninth most common malignancy in Saudi Arabia. It represented 3.2% of all newly diagnosed cancer cases in the year 2010. The aim of this study was to determine the epidemiology of skin cancer in relation to age, sex, and anatomic location among Saudi patients attending the Johns Hopkins Aramco Healthcare center in Dhahran, Eastern province of Saudi Arabia. We retrospectively reviewed the surgical pathology records of Saudi nationals from 1995 to 2014 at the Johns Hopkins Aramco Healthcare center, which directly provides for the healthcare needs of Saudi Aramco company employees and dependents in the Eastern Province of Saudi Arabia. Tumor metastases to skin, skin involvement by primary breast carcinoma, and B-cell leukemia/lymphoma with secondary involvement by skin were excluded. The total number of primary skin tumors was 204. The commonest cutaneous malignancies were basal cell carcinoma (36%) followed by squamous cell carcinoma (23%), with the head and neck being the commonest location for both tumors. Mycosis fungoides (MF) was the third most common malignancy (11%). Malignant melanoma was the fourth commonest skin malignancy (7%) with the lower extremities being the commonest location. The four most common skin cancers in our tertiary center in the Eastern Province of Saudi Arabia were squamous cell carcinoma, basal cell carcinoma, MF, and malignant melanoma. Other regions of Saudi Arabia report a similar pattern of skin cancers as our center, with MF having a higher frequency at our center.

  1. Operators in Yemen draw warning from Saudis

    Energy Technology Data Exchange (ETDEWEB)

    1992-05-04

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

    Full Text Available Background: The aim of this study was to explore Saudi cancer patients' views regarding cancer information disclosure and whether differences existed between regions or gender.Methods: In this cross-sectional questionnaire-based prospective survey, we interviewed 332 Saudi cancer patients who received oncological care at King Fahd University Hospital, Al-Khobar, Saudi Arabia from July 2002 to July 2009 to explore their attitudes regarding disclosure of cancer information. Results: The vast majority of Saudi cancer patients wanted to know the diagnosis of cancer (98% and only 2% wanted the information to remain undisclosed. Seventy percent of the women wanted family members to know compared to only 39% of themen (P<0.001. Only 10% of the patients wanted their friends to know. In this study,99% and 98%, respectively, wanted to know about the benefits of therapy and about their diagnosis of cancer. Of both genders, 98% also wanted to know the side effects of therapy and the prognosis. The attitudes of Saudi men and women with cancer were almost identical apart from sharing information with their family members. 99% ofeastern region cancer patients wanted the diagnosis of cancer disclosed compared to74% of those from other regions (P=0.04. Conclusion: The findings of this study indicated that most Saudi cancer patients wanted disclosure of cancer information. Significantly more women than men wanted to share information with their family. More Eastern region patients wanted to know about their diagnosis of cancer compared to patients from other regions.

  4. The Spectrum of Glomerulonephritis in Saudi Arabia: The Results of the Saudi Registry

    2000-01-01

    Full Text Available Only few studies regarding glomerulonephritis, with relatively small numbers of patients, have so far been published from different centers in Saudi Arabia, and have reported conflicting results regarding the patterns, even in the same city. The possible reasons for these differences include the small number of patients in the different studies, differences in the indications for renal biopsies, referral bias, geographical differences, and, sometimes, the non-availability of the necessary diagnostic facilities in the reporting centers. In order to overcome these problems, a registry for glomerulonephropathy was attempted in Saudi Arabia. Six large referral hospitals from different regions of Saudi Arabia participated in this registry. Biopsy reports and clinical information of 1294 renal biopsies were obtained. There were 782 renal biopsies due to glomerulonephritis (GN accounting for 77.2% of the total biopsies. Five hundred eighty seven (72.6% were primary glomerulonephritidis. Focal and segmental glomerulosclerosis (FSGS (21.3% and membrano-proliferative glomerulonephritis (MPGN (20.7% were the most common types found in the primary glomerulonephritidis. Membranous glomerulonephritis (MGN was present in only 10.6% of the cases. IgA nephropathy was found in 6.5% of the cases. Of the secondary glomerulo-nephritides, systemic lupus erythematosus (SLE was the most common indication for biopsy (57.0% and amyloidosis was found in only 3.2% of the biopsies. In conclusion, FSGS and MPGN were the most common forms of primary glomerulonephritis in adult patients in Saudi Arabia. MGN was not as common as in the western world. SLE was the commonest cause of secondary GN. Amyloidosis was not as common as in other Arab countries. There is a need for more centers from Saudi Arabia to join this national GN registry. Similar registries can be established in different Arab countries, which all would, hopefully, lead to a Pan-Arab GN registry.

    Cervical cancer is a common and an important public health problem for adult women in developing countries. In contrast, cervical cancer incidence is low in Saudi Arabia. High-risk types of human papilloma viruses (HPV16 and HPV18) are the most significant risk factors for cervical cancer. HPV16/18-E6 oncoprotein is associated with HPV etiology, viral persistence and epithelial transformation. Cell cycle protein p16 INK4a (p16) plays an important role in the pathophysiology of cervical carcinomas. The aims of this study were to investigate the expression of HPV16/18-E6 and p16 in uterine cervical carcinomas in Qassim Region--Saudi Arabia, and to relate the results to the established clinicopathological prognostic parameters (age of the patient, educational level, birth control methods, number of pregnancy, smoking status, degree of histological differentiation, clinical stage, and lymph node metastasis) The study included 40 specimens of uterine cervical squamous cell carcinomas diagnosed and confirmed by biopsy. Histopathological classification of cervical tumors cases was performed according to the International Federation of Gynecology and Obstetrics (FIGO). Immunohistochemical analysis for HPV16/18-E6 and p16 were carried out on formalin-fixed paraffin-embedded sections of cervical tissues using avidin-biotin peroxidase method. There was a significant statistical correlation between HPV16/18-E6 expression in cervical carcinoma and nationality, smoking status and size of the tumor. HPV16/18-E6 oncoprotein expression in normal lymphocytes and endothelial cells in the tumor tissues and the adjacent normal cervical tissues suggest the possibility that HPV infection might spread to other organs through blood circulation. P16 expression has been correlated with high grade, stage of cervical SCC and HPV16/18-E6 expression. The current study supports the critical function of p16 and HPV16/18-E6 as specific markers for cervical carcinoma. However the potential for usage

    2016-01-01

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

    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.

    Leprosy is a chronic disease caused by Mycobacterium leprae. Although the occurrence of leprosy has declined in Saudi Arabia, it has not yet been eradicated. To our knowledge, this descriptive retrospective study is the first to assess the clinical presentation of leprosy at the time of diagnosis in Saudi Arabia. All study subjects were leprosy patients admitted to Ibn Sina hospital, the only referral hospital for leprosy in Saudi Arabia, between January 2000 and May 2012. A total of 164 subjects, the majority of whom (65%) were between 21 and 50 years of age, were included, and the male-to-female ratio was 2.8:1. Of these 164 patients, 63% were Saudis, and 77% of all admitted patients were from the western region. Lepromatous leprosy was observed most frequently (33%), and 31% of cases had a positive history of close contact with leprosy. At the time of diagnosis, 84% of all subjects presented with skin manifestation. The prevalence of neurological deficit at the time of diagnosis was 87%. Erythema nodosum leprosum (E.N.L.) developed in only 10% of all subjects. Further studies are needed to determine the clinical characteristics pertaining to each type of leprosy in the region, and training courses in caring for and diagnosing patients with leprosy should be organized for health workers.

    This paper aims to assess trainees' satisfaction with the process and assessment aspects of the Saudi Diploma of Family Medicine (SDFM). This cross-sectional study was conducted in February 2015 among trainees undertaking the SDFM. A questionnaire was distributed to all trainees in four examination centres in Saudi Arabia, under the supervision and guidance of the investigators (four members of the scientific committee of SDFM). There was a total of 97 participants in this study, the majority of whom were Saudis. More than 85% were satisfied with most elements of training including; an adequate number and variety of patients and cases, allocating time for training, giving regular written evaluation. Satisfaction with mentoring and giving constructive feedback scored less well and trainees were less satisfied with some hospital clinical rotations, which requires further exploration.

    In this study, a cohort of 182 patients [55 hepatocellular carcinoma (HCC) and 127 non-HCC] infected with hepatitis B virus (HBV) in Saudi Arabia was investigated to study the relationship between sequence variation in the enhancer II (EnhII), basal core promoter (BCP) and precore regions of HBV genotype D (HBV/D) and the risk of HCC. HBV genotypes were determined by sequencing analysis and/or enzyme-linked immunosorbent assay. Variations in the EnhII, BCP and precore regions were compared between 107 non-HCC and 45 HCC patients infected with HBV/D, followed by age-matched analysis of 40 cases versus equal number of controls. Age and male gender were significantly associated with HCC (p = 0.0001 and p = 0.03, respectively). Serological markers such as aspartate aminotransferase, albumin and anti-HBe were significantly associated with HCC (p = 0.0001 for all), whereas HBeAg positivity was associated with non-HCC (p = 0.0001). The most prevalent HBV genotype was HBV/D (94%), followed by HBV/E (4%), HBV/A (1.6%) and HBV/C (0.5%). For HBV/D1, genomic mutations associated with HCC were T1673/G1679, G1727, C1741, C1761, A1757/T1764/G1766, T1773, T1773/G1775 and C1909. Age- and gender-adjusted stepwise logistic regression analysis indicated that mutations G1727 [odds ratio (OR) = 18.3; 95% confidence interval (CI) = 2.8-118.4; p = 0.002], A1757/T1764/G1766 (OR = 4.7; 95% CI = 1.3-17.2; p = 0.01) and T1773 (OR = 14.06; 95% CI = 2.3-84.8; p = 0.004) are independent predictors of HCC development. These results implicate novel individual and combination patterns of mutations in the X/precore region of HBV/D1 as predictors of HCC. Risk stratification based on these mutation complexes would be useful in determining high-risk patients and improving diagnostic and treatment strategies for HBV/D1.

    The efficient use of water resources in arid region has become highly relevant in the evaluation and mining planning, since the exploration phase to closure. The objective of the numerical groundwater model was to assess the potential for groundwater extraction to meet mine water demand from one of the driest area in the world. Numerical groundwater models were used to assess groundwater resource. Modelling was undertaken using MODFLOW-SURFACT code, an advanced MODFLOW based code, within the framework of Visual MODFLOW version 4.6. A steady state model was developed to assess the regional groundwater flow pattern and to calibrate the recharge and hydraulic conductivity parameters in the model. The model was calibrated with a correlation of coefficient of 0.997, and root-mean-squared error is 0.3 m. A transient simulation model was used to predict the impact of 1.5 million cubic metre/year extraction for 10 years on the main aquifer hydrogeological regime, including after cession of pumping. Modelling simulated four hydrogeological scenarios. Model results for the 'worst case' scenario suggested that the Saq Sandstone aquifer should be capable of supplying the mine water demand (1.5 million cubic metre (MCM)/year) for 10 years. However, the long-term water-level drawdown shows a continuous decrease without achieving steady state conditions; thus, the majority of water is being taken from aquifer storage, and in the long term, there will be a mutual interference from a borefield located to the north of the model area. In this area, the hydraulic gradient is relatively steep and over-pumped for more than 28 years. Other scenario shows that there will be a recovery of around 8 m out of the 11.6-m drawdown, after 18 years of cession of pumping, implying that the aquifer will be stressed and a large percentage of water taken from aquifer storage. To minimise hydrogeological impacts, it is recommended to laterally spread out production bores, bores should be located

    Rabbit hemorrhagic disease is an acute fatal highly contagious viral infectious disease that causes high losses among rabbitries. The disease was first reported in China in 1984 and later on in Saudi Arabia in 1996. The aim of this study was to investigate the emergence and pathogenicity of new rabbit hemorrhagic disease virus (RHDV) strains in Saudi Arabia. The pathogenicity was confirmed by inoculation in susceptible rabbits. Three RHDV strains were detected by reverse transcriptase polymerase chain reaction (RT-PCR) using primers targeting VP60 capsid protein gene in infected rabbitries during 2012 and 2013. These strains clustered into two genetically distinct genogroups related to year of isolation (G2 and G3). All new Saudi Arabia viruses clustered with the European strains, while the old strains clustered with strains from China and America. Based on amino acids and nucleotide sequences, the Saudi Arabia strains (RHD/1/SA/2012, RHD/2/SA/2012, and RHD/3/SA /2013) had high identity with Mexico89, Ca11-ITA, and 00-13,FRA virus; on the other hand, there was a relatively high identity with Bahrain strain. The evolutionary relationship of Saudi RHDVs strains revealed significant nucleotides and amino acid substitutions in hypervariable region E, suggesting the emergence of new RHDVs circulating in Saudi Arabia rabbitries. These antigenic changes represented by the antigenic index might be a potential cause of vaccination failure and raises the need to review the vaccination strategies against RHD.

    The genetic variability and circulation pattern of human respiratory syncytial virus group B (HRSV-B) strains, identified in Riyadh during the winters of 2008 and 2009, were evaluated by partial sequencing of the attachment (G) protein gene. The second hypervariable region (HVR-2) of G gene was amplified by RT-PCR, sequenced and compared to representatives of different HRSV-B genotypes. Sequence and phylogenetic analysis revealed that all Saudi strains belonged to the genotype BA, which is characterized by 60-nucleotide duplication at HVR-2. Only strains of 2008 were clustered with subgroup BA-IV, while those isolated at 2009 were clustered among the most recent subgroups (particularly BA-X and CB-B). Amino acid sequence analysis demonstrated 18 amino acid substitutions in Saudi HRSV-B strains; among which five are specific for individual strains. Furthermore, two potential N-glycosylation sites at residues 230 and 296 were identified for all Saudi strains, and an additional site at amino acid 273 was found only in Riyadh 28/2008 strain. O-glycosylation was predicted in 42-43 sites, where the majority (no = 38) are highly conserved among Saudi strains. The average ratio between non-synonymous and synonymous mutations (ω) implied stabilizing selection pressure on G protein, with evidences of positive selection on certain Saudi strains. This report provides preliminary data on the circulation pattern and molecular characteristics of HRSV-B strains circulating in Saudi Arabia.

    The social, political, and economic implications of the immigrant presence in Saudi Arabia are explored. The author notes that about one-third of the population of the country is made up of working nonnationals. The tensions that exist are examined, with reference to the exclusion of the migrants from Saudi Arabian society and the extreme imbalance in the sex ratio caused by predominately male migration. The author suggests that dependence on migrant labor is likely to increase rather than decrease as Saudi nationals are oriented toward nontechnical studies and Saudi women are excluded from the labor force.

Existing literature demonstrates that these populations are well adapted for the harsh extremes of the region. Populations of A. m. jemenitica native to Saudi Arabia are far more heat tolerant than the standard races often imported from Europe. Central Saudi Arabia has the highest summer temperatures for the Arabian Peninsula, and it is in this region where only A. m. jemenitica survives, while other subspecies fail to persist. The indigenous race of Saudi Arabia differs from other subspecies in the region in some morphological, biological, and behavioral characteristics. Further taxonomic investigation, as well as molecular studies, is needed in order to confirm whether the Saudi indigenous bee populations represent a race distinct from A. m. jemenitica, or merely an ecotype of this subspecies.

    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.

    Flaviviruses represent a global public health concern. They consist of ∼70 viruses with almost half of them causing human diseases with unspecified febrile illnesses. Cities in western Saudi Arabia are endemic for viruses (DENV) with sporadic infections due to Alkhumra hemorrhagic fever virus (AHFV). They also represent a major destination for travelers coming for annual religious pilgrimages (Hajj and Umrah) from all over the world. However, whether other flaviviruses are circulating is not known because of the limited number of surveillance studies. Here, we retrospectively screened 690 samples for flaviviruses in samples from patients with unexplained febrile illnesses between 2010 and 2015 in western Saudi Arabia using a pan-flaviviruses RT-PCR assay. Despite Zika virus RNA was not detected, this study confirms circulation and/or sporadic spread of DENV-2, DENV-3, and AHFV, higher prevalence of DENV-2, and a role for visitors from DENV endemic countries in DENV importation into the Kingdom. Further analysis also showed very low genetic diversity of AHFV confirming its slow microevolution. Accordingly, continuous and prospective surveillance for flaviviruses using such assay are warranted in Saudi Arabia which receives millions of Muslims annually to implement effective control measures in light of the global widespread and outbreaks of several flaviviruses.

    Full Text Available During the last decade many electronic databases of vegetation plots were established in many countries around the world. These databases contain valuable phytosociological information assisting both governmental and NGO (Non-governmental organizations agencies to formulate strategies and on-ground plans to manage and protect nature resources. This paper provides an account on aims, current status and perspectives of building of a vegetation database for the Central Region (Najd of Saudi Arabia – the founding element of the Saudi Vegetation Database (SVD. The data stored by the database are sample plots (vegetation relevés collected according to the field techniques of the Braun-Blanquet approach (lists of taxa accompanied by semi-quantitative cover assessment, and are accompanied by general vegetation characteristics such as vegetation layering and cover, information on life-form of the recorded species, geographical coordinates, altitude, soil typology, topography and many more. More than 2900 vegetation-plot records (relevés have so far been collected in the Najd region; of these more than 2000 have already been stored using the Turboveg database platform. These field records cover many habitats such as depressions, wadis (dry river beds, agricultural lands, sand dunes, sabkhas, and ruderal habitats. The ecological information collected in the database is currently the largest set of vegetation data collated into a database in the Middle East. These data are of great importance for biodiversity studies in Saudi Arabia, since the region is recording a loss of biodiversity at a fast rate due to environmental problems such as global warming and land-use changes. We envisage that this database would catalyze further data collection on vegetation of the entire Arabian Peninsula, and shall serve as one of the most important datasets for classification and mapping of the vegetation of the Kingdom of Saudi Arabia.

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

    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.

    Full Text Available Little is known about the geographic distribution of common cancers in Saudi Arabia. We explored the spatial incidence patterns of common cancers in Saudi Arabia using spatial autocorrelation analyses, employing the global Moran’s I and Anselin’s local Moran’s I statistics to detect nonrandom incidence patterns. Global ordinary least squares (OLS regression and local geographically-weighted regression (GWR were applied to examine the spatial correlation of cancer incidences at the city level. Population-based records of cancers diagnosed between 1998 and 2004 were used. Male lung cancer and female breast cancer exhibited positive statistically significant global Moran’s I index values, indicating a tendency toward clustering. The Anselin’s local Moran’s I analyses revealed small significant clusters of lung cancer, prostate cancer and Hodgkin’s disease among males in the Eastern region and significant clusters of thyroid cancers in females in the Eastern and Riyadh regions. Additionally, both regression methods found significant associations among various cancers. For example, OLS and GWR revealed significant spatial associations among NHL, leukemia and Hodgkin’s disease (r² = 0.49–0.67 using OLS and r² = 0.52–0.68 using GWR and between breast and prostate cancer (r² = 0.53 OLS and 0.57 GWR in Saudi Arabian cities. These findings may help to generate etiologic hypotheses of cancer causation and identify spatial anomalies in cancer incidence in Saudi Arabia. Our findings should stimulate further research on the possible causes underlying these clusters and associations.

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

    Seismic hazard assessment is carried out by utilizing deterministic approach to evaluate the maximum expected earthquake ground motions along the Western Coastal Province of Saudi Arabia. The analysis is accomplished by incorporating seismotectonic source model, determination of earthquake magnitude ( M max), set of appropriate ground motion predictive equations (GMPE), and logic tree sequence. The logic tree sequence is built up to assign weight to ground motion scaling relationships. Contour maps of ground acceleration are generated at different spectral periods. These maps show that the largest ground motion values are emerged in northern and southern regions of the western coastal province in Saudi Arabia in comparison with the central region.

    The wetlands of Saudi Arabia are located in a water-stressed region that is highly vulnerable to climate and other global changes. Sebkhas, mudflats, mangroves, and wadis are the dominant wetlands in the arid regions of North Africa and the Arabian Peninsula. These unique wetlands are recognized as a sanctuary for biodiversity and for their economic services generated from mineral extraction, agriculture, and grazing. Despite their ecological values and societal services, the long-term permanence of Saudi Arabia's wetlands faces strong challenges resulting from human activities associated with sustained population growth, habitat degradation, and coastal development. This paper consolidates a literature review of Saudi Arabia's wetlands from local to global importance, highlights their biodiversity, and identifies threats and evolution of these vulnerable ecosystems in the arid Arabian Peninsula by focusing on the status of key freshwater taxa (Odonata, freshwater fishes, amphibians, and waterbirds) and documenting changes affecting important wetlands.

  15. EGovernment Stage Model: Evaluating the Rate of Web Development Progress of Government Websites in Saudi Arabia

    2011-09-01

    Full Text Available This paper contributes to the issue of eGovernment implementation in Saudi Arabia by discussing the current situation of ministry websites. It evaluates the rate of web development progress of vital government websites in Saudi Arabia using the eGovernment stage model. In 2010, Saudi Arabia ranked 58th in the world and 4th in the Gulf region in eGovernment readiness according to United Nations reports. In particular, Saudi Arabia has ranked 75th worldwide for its online service index and its components compared to the neighbouring Gulf country of Bahrain, which was ranked 8th for the same index. While this is still modest in relation to the Saudi government’s expectation concerning its vision for eGovernment implementation for 2010, and the results achieved by the neighbouring Gulf countries such as Bahrain and the United Arab Emirates on the eGovernment index, the Saudi government has endeavoured to meet the public needs concerning eGovernment and carry out the implementation of eGovernment properly. Governments may heed the importance of actively launching official government websites – the focus of this study – as the main portals for delivering their online services to all the different categories of eGovernment (including G2C, G2B, and G2G. However, certain Saudi ministries have not given due attention to this vital issue. This is evidenced by the fact that some of their websites are not fully developed or do not yet exist, which clearly impedes that particular ministry from appropriately delivering eServices.

    Recent evidence has pointed out an association between vitamin D deficiency and coronary heart disease (CHD). Due to the growing epidemic of CHD and vitamin D deficiency in Saudi Arabia, exploring the role of vitamin D in the prevention of CHD is crucial. The aim of this study was to examine the association between vitamin D status and CHD in Saudi Arabian adults. This case-control study included 130 CHD cases and 195 age-sex matched controls. Study subjects were recruited from three hospitals in the western region of Saudi Arabia. Study participants were interviewed face-to-face to collect data on their socio-demographic characteristics and family history of CHD.

    Full Text Available This sociolinguistics study investigates a new phenomenon that has recently surfaced in the field of code-switching among Saudi females residing in the Western region of Saudi Arabia. This phenomenon basically combines bound Arabic pronouns, tense markers or definite article to English free morphemes or the combination of bound English affixes to Arabic morphemes. Moreover, the study examines the factors that affect this type of code-switching. The results of the study indicate that this phenomenon provides data that invalidates Poplack’s (1980 universality of the ‘Free Morpheme Constraint’. It is also concluded that the main factors that influence this type of code-switching is solidarity and group identity among other factors.

    Full Text Available Background: Vitamin D deficiency has been correlated with several diseases and injuries including diabetes, osteoporosis, fractures, and falls. In the Kingdom of Saudi Arabia (KSA, current data on vitamin D status are lacking. Aims: To inform Saudi public health authorities on the current status of blood levels vitamin D deficiency, we analyzed data from the Saudi Health Interview Survey. Materials and Methods: The Saudi Health Interview Survey (SHIS is a cross-sectional national multistage survey of individuals aged 15 years and above on sociodemographic characteristics, tobacco consumption, diet, physical activity, health care utilization, different health-related behaviors, and self-reported chronic conditions. A total of 10,735 participants completed a health questionnaire and were invited to the local health clinics for biomedical exams. Results: 62.65% of female Saudis and 40.6% of male Saudis aged 15 years and above are deficient in vitamin D. Out of them, less than 1% males and less than 2% females consume vitamin D supplements. Women who have never married and obese individuals are more likely to be deficient in vitamin D, compared to men who were currently married and nonobese individuals. Those consuming vitamin D supplements are less likely to be deficient in vitamin D. Conclusions: Our study showed a high prevalence of vitamin D deficiency among Saudi men and women, and the results call for an increased awareness to ensure adequate levels of vitamin D for better health in Saudi Arabia. Moreover, our findings are certainly relevant for other countries in the Gulf region or countries with similar cultures, clothing, and religions.

    Full Text Available In view of the increasing concern among English language teachers dealing with students from Saudi Arabia, as it manifests in TESOL community discussions, about the uniqueness of Saudi Arabian EFL learners, this paper attempts to document the outcome of a study of their distinctiveness from the perspective of expatriate teachers working for PYPs (Preparatory Year Programs in Saudi Arabia. This study examines the distinctiveness with regard to the learning attitudes of Saudi students that are often cultivated by the culture and academic environment in their homeland. Employing an emic approach for collecting the required data an analysis was carried out in light of the other studies on ‘education’ in Saudi Arabia that have particular reference to the factors that can positively influence student motivation, student success and the academic environment. The findings were used in constructing the rationale behind such distinctiveness. Assuming that the outcome of the discussion on the findings of this exploration can be helpful for teachers in adapting their teaching methodology and improving their teacher efficacy in dealing with students both from the kingdom and in the kingdom, some recommendations are made.

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

    The Kingdom of Saudi Arabia occupies four-fifths of the Arabian Peninsula, with a land area of 2 million square kilometres. Saudi Arabia holds a unique position in the Islamic world, as the custodian of the two holiest places of Islam, in Mecca and Medina. Annually, some 2 million Muslims from over 140 countries embark on Hajj. This extraordinary en masse migration is a unique forum for the study of travel epidemiology since the Hajj carries various health risks, both communicable and non-communicable, often on a colossal scale. Non-communicable hazards of the Hajj include stampede and motor vehicle trauma, fire-related burn injuries and accidental hand injury during animal slaughter. Communicable hazards in the form of outbreaks of multiple infectious diseases have been reported repeatedly, during and following the Hajj. Meningococcal meningitis, gastroenteritis, hepatitis A, B and C, and various zoonotic diseases comprise some of the possible infectious hazards at the Hajj. Many of these infectious and non-infectious hazards can be avoided or averted by adopting appropriate prophylactic measures. Physicians and health personnel must be aware of these risks to appropriately educate, immunize and prepare these travellers facing the unique epidemiological challenges of Hajj in an effort to minimize untoward effects. Travel epidemiology related to the Hajj is a new and exciting area, which offers valuable insights to the travel specialist. The sheer scale of numbers affords a rare view of migration medicine in action. As data is continually gathered and both national and international policy making is tailored to vital insights gained through travel epidemiology, the Hajj will be continually safeguarded. Practitioners will gain from findings of travel related epidemiological changes in evolution at the Hajj: the impact of vaccinating policies, infection control policies and public health are afforded a real-world laboratory setting at each annual Hajj, allowing us to

    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.

  17. SCIENTIFIC POLICY OF SAUDI ARABIA: INTERNATIONAL SCIENCE AS A BASIS FOR DEVELOPMENT

    Directory of Open Access Journals (Sweden)

    T. I. Tyukaeva

    2016-01-01

    Full Text Available In less than a century of its existence Saudi Arabia has developed from mass illiteracy and lack of education of its population into the current state of complex structure of educational and research institutions and organizations equipped with most modern and advanced technologies and top world specialists in accordance with the highest international standards. It is especially important that the Kingdom has managed to achieve such success in no time. Until lately scientifi c development in Saudi Arabia was mostly concentrated on applied research, especially in the Kingdom’s key economic sphere – energy. Despite the country’s abundant financial resources, science was considerably underfunded and lacked any development strategy. Meanwhile, in the last 15 years the Saudi Kingdom has made a huge leap in scientifi c development with a clear action plan worked out, a solid structure of scientifi c institutes formed and the world experience effi ciently used. The success came with the Saudi authorities’ realization of the importance of scientifi c and technical progress both for the national economy and political positions of the state in the region and in the world. The article aims to analyze the scientifi c policy of Saudi Arabia on the stage of its birth and in the current state by means of studying offi cial documents, statistics and the existing institutes in the scientifi c system of the Kingdom. The author concludes that the key features of the Saudi scientifi c policy are prevailing role of the state, priority of applied over fundamental research and internalization with serious dependency on foreign support in the absence of a national scientifi c tradition.

    The synoptic circulation over Saudi Arabia is complicated and frequently governed by the effect of large-scale pressure systems. In this work, we used NCEP-NCAR global data to illustrate the relationship between climatic variables and the main pressure systems that affect the weather and climate of Saudi Arabia, and also to investigate the influence of these pressure systems on surface air temperature (SAT) and rainfall over the region in the winter season. It was found that there are two primary patterns of pressure that influence the weather and climate of Saudi Arabia. The first occurs in cases of a strengthening Subtropical High (SubH), a weakening Siberian High (SibH), a deepening of the Icelandic Low (IceL), or a weakening of the Sudanese Low (SudL). During this pattern, the SubH combines with the SibH and an obvious increase of sea level pressure (SLP) occurs over southern European, the Mediterranean, North Africa, and the Middle East. This belt of high pressure prevents interaction between midlatitude and extratropical systems, which leads to a decrease in the SAT, relative humidity (RH) and rainfall over Saudi Arabia. The second pattern occurs in association with a weakening of the SubH, a strengthening of the SibH, a weakening of the IceL, or a deepening of the SudL. The pattern arising in this case leads to an interaction between two different air masses: the first (cold moist) air mass is associated with the Mediterranean depression travelling from west to east, while the second (warm moist) air mass is associated with the northward oscillation of the SudL and its inverted V-shape trough. The interaction between these two air masses increases the SAT, RH and the probability of rainfall over Saudi Arabia, especially over the northwest and northeast regions.

    Human brucellosis is an important zoonotic disease and is especially concerning in the Kingdom of Saudi Arabia (KSA), where livestock importation is significant. We analyzed reported human brucellosis disease trends in KSA over time to help policymakers understand the magnitude of the disease and guide the design of prevention and control measures. By using data from the national registry from 2004 to 2012, we calculated the cumulative numbers by age group and months. Trends of incidence rates (IRs) by gender, nationality, and region were also calculated. We found that there was a greater number of cases (19,130) in the 15-44 years age group than in any other age group. The IRs significantly decreased from 22.9 in 2004 [95% confidence interval (CI)=22.3, 23.5] to 12.5 in 2012 (95% CI=12.1, 13). Males had a significantly greater IR than females. Most cases were reported during spring and summer seasons. The IR of Saudi citizens was significantly greater than that of non-Saudis, but this difference reduced over time. The IRs of Al-Qassim, Aseer, and Hail were in the highest 25th percentile. Young, male Saudi citizens living in highly endemic areas were at greatest risk of acquiring brucellosis. We recommend vaccinating susceptible animals against brucellosis and increasing the public's awareness of preventive measures.

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

  3. Evaluation of Different Soil Salinity Mapping Using Remote Sensing Techniques in Arid Ecosystems, Saudi Arabia

    Full Text Available Land covers in Saudi Arabia are generally described as salty soils with sand dunes and sand sheets. Waterlogging and higher soil salinity are major challenges to sustaining agricultural practices in Saudi Arabia principally within closed drainage basins. Agricultural practices in Saudi Arabia were flourishing in the last two decades. The newly reclaimed lands were added annually and distributed all over the country. Irrigation techniques are mostly modernized to fulfill water saving strategies. Nevertheless, water resources in Saudi Arabia are under stress and groundwater levels are depleted rapidly due to heavy abstraction that may exceed crop water requirements in most of the cases due to high evaporation rates. The excess use of irrigational water leads to severe soil salinity problems. Applications of remote sensing technique in agricultural practices became widely distinctive and cover multidisciplinary principal interests on both local and regional levels. The most important remote sensing applications in agricultural practices are vegetation indices which are related to vegetation and water especially in an arid environment. Soil salinity mapping in an arid ecosystem using remote sensing data is a demanding task. Several soil salinity indices were implemented and evaluated to detect soil salinity effectively and quantitatively. Thematic maps of soil salinity were satisfactorily produced and assessed.

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

    Full Text Available Objective: To evaluate tuberculosis (TB incidence rates and trends over a period of 20 years (1991-2010 and assess the impact of the National TB Control Program (NTP on incidence trends. Methods: This is a retrospective study of TB surveillance data reported by the Ministry of Health. We evaluated TB incidence data by nationality, age, and region of the country and assessed incidence trends over 20 years of study. Chi-squared test was used to assess trend change and its significance. Results: There were a total of 64,345 reported TB cases over the study period. Of these 48% were Non-Saudis. TB annual incidence rate ranged between 14 and 17/100,000. For Saudis, the rate ranged between 8.6 and 12.2/100,000. Non-Saudis had 2-3 times higher incidence. Disease trend was rising over the first 10 years of the study period then it started to fall slightly. The incidence increased with age, but only people older than 45 years showed a declining trend. Regional variations were observed. Makkah and Jazan regions had the highest incidence rates. Disease trends were rising over the last 10 years in Makkah and Central regions. Conclusion: TB control seems to be facing some challenges in several regions of the Kingdom. NTP needs to evaluate and improve TB control strategies in order to reduce disease incidence to elimination levels.

    During the last decade, the rapid economic development in Saudi Arabia resulted in an unbalanced dietary intake pattern within the general population. Consequently, metabolic syndrome was also documented to be highly prevalent in the Middle-East region. We aimed to examine the relationship between selected dietary nutrient intakes and the prevalence of metabolic syndrome in the general adult population of Riyadh, Saudi Arabia. In this cross-sectional study, 185 adult Saudis aged 19 to 60 years (87 males and 98 females (mean age 35.6 ± 13.2 and 37.6 ± 11.7 years, respectively)) were included. The criteria for metabolic syndrome were based on the International Diabetes Foundation (IDF) criteria, and the dietary food intake was assessed by two 24-h dietary recall methods. The odd ratios (ORs) of metabolic syndrome risk across quartiles of selected dietary nutrients were significantly lower for carbohydrates and proteins, as well as for vitamins A, C, E and K, calcium, zinc and magnesium (p nutrients among the general population of Saudi Arabia raises concern, and this dietary imbalance could increase the risk of metabolic syndrome, particularly in adult Saudi females.

    2016-04-01

    Annual rainfall records of 20 stations for 30 years are used in order to detect rainfall regimes and climatic features of Saudi Arabia using harmonic analysis techniques. In this study, the percentages of variance, amplitudes, and phase angles are calculated in order to depict the spatial and temporal characteristics of the country's rainfall. The first harmonic explains 42 % of rainfall variation in the western (W) region. This percentage increases toward east (E) and north (N) with 69 and 67 %, respectively. In the southwest (SW) region, the percentages explain 43 % of rainfall variation. The percentages of variance in W and SW are lower than in the E, NW, and central (C) regions. This implies significant contributions of the second harmonic in W and SW regions with 26 and 16 %, respectively. The high percentages of the second and third harmonics in W and SW regions suggest that these two regions are affected by different weather systems at different times. The SW region has the highest amplitudes of the first, second, and third harmonics. The amplitude of the first harmonic reaches to 21 mm in SW and 9 mm in both C and E regions. The time of maximum rainfall is calculated using phase angle; the result reflects that maximum rainfall is shifted forward on the time axis toward the spring season in SW and C regions, January in E and NW regions, and October and November in the W region. This reveals that the SW region is a completely different climatic region, though some of what affects this region also affects the central region. Conditions in the E and NW regions are mainly affected by Mediterranean weather systems, while the W region is affected by unstable conditions caused by the active Red Sea Trough (RST) in October and November.

    Full Text Available Innovation and entrepreneurship are critical elements in the transition to the knowledge-based economy and future competition. Unfortunately, innovation tends to be absent in Arab states for many reasons. To promote innovation in Saudi Arabia, for instance, it is necessary to support inventors’ ideas to turn inventions into start-up companies, which are companies in their early stage. At the same time, it seems that there is a need for more academic research to study the success factors of Saudi information and communication technology (ICT start-up companies. ICT start-ups are important to the economy because they are needed for the progress of all industries. Therefore, this study will identify the factors that lead to successful ICT start-up projects. Then, it will develop a model for the best practices in the interplay among the defined factors that will increase the opportunity to initiate successful start-ups. This research involves a factor analysis study based on a quantitative method to measure the interdependences among the success factors for ICT start-ups. The identified factors are verified using a sample of Saudi start-up companies. The study will contribute to enhancing the technological content to diversify the Saudi economy in order to prepare for the post-oil era. The study result is a survivability model for Saudi-incubated ICT startups. The resulting model has two phases, as follows: (1 the incubation period, which includes the relationships among three factors leading to constant and successful updates and upgrades of the ICT startup business model; and (2 the postincubation period, which include relationships among the three factors that help to deal with the changing nature of the market and the emergence of competing products. This solution can be applied within startups with similar conditions.

    2004-06-01

    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.

  20. Core inflation indicators for Saudi Arabia

    Directory of Open Access Journals (Sweden)

    Alkhareif Ryadh M.

    2015-01-01

    Full Text Available This paper constructs and analyzes core inflation indicators for Saudi Arabia for the period of March 2012 to May 2014 using two alternative approaches: the exclusion method (ex food and housing/rent and the statistical method. The findings of the analysis suggest that the ex food and housing/ rent inflation is more volatile than the overall CPI inflation over the sample period. In contrast, the statistical core inflation is relatively more stable and less volatile. Moreover, the ex food and housing/rent inflation is only weakly correlated with headline inflation, whereas the statistical core inflation exhibits a stronger correlation. This combination of lower volatility and higher correlation with headline inflation makes the statistical method a much better choice for policymakers. From a monetary policy standpoint, using a bundle of core inflation measures, including both properly constructed exclusion and statistical methods, is more desirable, especially when variation across measures is widespread, as is the case in Saudi Arabia.

    The geographic incidence of tumors usually uncovers the influence that environment, race and culture exert upon the prevalence of cancer. Therefore this study of tumors of the eye is presented as a baseline for Saudi Arabia between the years 1982G and 1989G. The most common malignant tumors, in decreasing order of frequency, are retinoblastoma, squamous cell carcinoma of the conjunctiva, basal cell carcinoma of the eyelid, and malignant melanoma. The most common benign tumors, in the same order, are nevi, epithelial cysts, hemangiomas and dermoid cysts. There are, in Saudi Arabia, certain unique features for retinoblastoma, squamous cell carcinoma, basal cell carcinoma and malignant melanoma. Furthermore, these conditions have distinctive incidence rates when compared with cancer incidence in Western countries.

However, there are many factors affecting the efficiency of training, and the views of interns are rarely considered. The main objective of this study was to explore the views of interns enrolled in Jazan University internship program during the year 2015. Subjects and methods: A web-based cross-sectional study was conducted in the Jazan region, Kingdom of Saudi Arabia, during the academic year 2015. To achieve the study goals, an online questionnaire was distributed to all interns (n=85 enrolled in the Jazan University internship program. Results: Results revealed that satisfaction with training was more evident in general surgery and pediatrics (76.1%, n=54 and 77.5%, n=55, respectively. Satisfaction was lowest for obstetrics and gynecology programs (45.1%, n=32, while in internal medicine it was 54.9% (n=39. Training in general surgery and pediatrics was rated as excellent by most of the interns (45.8% and 43.1%, respectively. The picture is reversed in obstetrics and gynecology, as 43.1% rated it as average. More than half of the study sample felt that they were well prepared to start the next step in their career at the end of internship (50.7%, while 25.4% felt that they were moderately prepared. Conclusion: It is clear that training quality in views of interns is variable across the major specialties, and there are some problems in obstetrics and gynecology training. More studies are needed to explore in-depth dimensions of internship training program in the Kingdom of Saudi Arabia. Keywords: Jazan University, internship program, gynecology and

    Full Text Available This study examines the apology strategies used by 30 Saudi EFL teachers in Najran, the Kingdom of Saudi Arabia (KSA, paying special attention to variables such as social distance and power and offence severity. The study also delineates gender differences in the respondents’ speech as opposed to studies that only examined speech act output by native and non-native speakers of English. To this end, the study employs a Discourse Completion Task (DCT that consists of 10 situations designed to test how the respondents would react if they imagine that they belong to different types of social status whether higher, lower or equal. In addition, social distance and power have been taken into consideration in designing the ten situations included in the test used in this study. The results reveal that Illocutionary Force Indicating Device (IFID is the most used apology strategy by the Saudi respondents followed by downgrading responsibility (DR, upgrader, offer of repair, taking on responsibility and then verbal redress. The results also reveal that gender has a great impact on the use of apology strategies in various ways. For instance, the IFID strategy and the upgrader strategy are used by males more than their female counterparts, whereas females use the DR strategy more than their male counterparts. It has been argued that some of the respondents’ answers to the test were influenced by their mother tongue, as reported in previous studies conducted on apology strategies. The study discusses the results elicited via the DCT and compares them with those of previous studies on apology strategies and other speech acts. Finally, the study concludes with recommendations for further research. Keywords: pragmatics, apology strategies, Saudi EFL teachers, interlanguage pragmatics, target culture

    Patient's satisfaction has emerged as a central focus of health-care delivery during the last decades, and nursing care became one significant component of patient's satisfaction. The purpose of this study is to examine patients' satisfaction with quality of nursing care provided in Saudi Arabia. Cross-sectional descriptive correctional design was used to recruit 100 patients from one regional hospital in Saudi Arabia. Data collected using structured interview from patients related to six dimensions of nursing care. Patients had a high level of satisfaction with nursing care provided (86% agreement rate). Language (56% disagreement rate), discharge information (56% disagreement rate) and availability (20% disagreement rate) have been identified with the lowest rates of patients satisfaction. Nursing leaders and health-care administrators need to maintain quality nursing care and develop strategies for improving nursing care emphasizing language as barrier and strategies of information dissemination.

    Full Text Available The common aim of all our daily activities is providing services to others or ourselves. Services provided by the government are called public services while those provided by some people to some others are called private services. Both types differ from country to country and from region to region. In Saudi Arabia, public services include education, health, police, trading, and environmental services. It is the aim of all government agencies in Saudi Arabia and other countries around the world to offer more services to their customers, improve the quality of their customer service, and enhance the existing services. Nowadays, most government agencies have already developed a number Information Systems (ISs to help their customers in applying for services and help their employees in processing the requested services. However, hardly a government agency utilizes the data in the employed ISs to improve the quality of its customer service. This paper is dedicated to addressing this gap by proposing a number of data analysis techniques that can be utilized to improve the quality of customer service and enhance the existing services in the Saudi government sector. Moreover, this article introduced a relational database structure that can be utilized to apply the proposed data analysis techniques.

    A survey was conducted to determine the status of Lucerne transient streak virus (LTSV) in three high-yielding alfalfa regions in central Saudi Arabia (Riyadh, Qassim, and Hail) during 2014. Three hundred and eight symptomatic alfalfa, and seven Sonchus oleraceus samples were collected. DAS-ELISA indicated that 59 of these samples were positive to LTSV. Two isolates of LTSV from each region were selected for molecular studies. RT-PCR confirmed the presence of LTSV in the selected samples using a specific primer pair. Percentage identity and homology tree comparisons revealed that all Saudi isolates were more closely related to each other but also closely related to the Canadian isolate-JQ782213 (97.1–97.6%) and the New Zealand isolate-U31286 (95.8–97.1%). Comparing Saudi isolates of LTSV with ten other sobemoviruses based on the coat protein gene sequences confirmed the distant relationship between them. Eleven out of fourteen plant species used in host range study were positive to LTSV. This is the first time to document that Trifolium alexandrinum, Nicotiana occidentalis, Chenopodium glaucum, and Lathyrus sativus are new host plant species for LTSV and that N. occidentalis being a good propagative host for it.

    The extensive harrat lava province of Arabia formed during the past 30 million years in response to Red Sea rifting and mantle upwelling. The area was regarded as seismically quiet, but between April and June 2009 a swarm of more than 30,000 earthquakes struck one of the lava fields in the province, Harrat Lunayyir, northwest Saudi Arabia. Concerned that larger damaging earthquakes might occur, the Saudi Arabian government evacuated 40,000 people from the region. Here we use geologic, geodetic and seismic data to show that the earthquake swarm resulted from magmatic dyke intrusion. We document a surface fault rupture that is 8 km long with 91 cm of offset. Surface deformation is best modelled by the shallow intrusion of a north-west trending dyke that is about 10 km long. Seismic waves generated during the earthquakes exhibit overlapping very low- and high-frequency components. We interpret the low frequencies to represent intrusion of magma and the high frequencies to represent fracturing of the crystalline basement rocks. Rather than extension being accommodated entirely by the central Red Sea rift axis, we suggest that the broad deformation observed in Harrat Lunayyir indicates that rift margins can remain as active sites of extension throughout rifting. Our analyses allowed us to forecast the likelihood of a future eruption or large earthquake in the region and informed the decisions made by the Saudi Arabian government to return the evacuees.

Rather than extension being accommodated entirely by the central Red Sea rift axis, we suggest that the broad deformation observed in Harrat Lunayyir indicates that rift margins can remain as active sites of extension throughout rifting. Our analyses allowed us to forecast the likelihood of a future eruption or large earthquake in the region and informed the decisions made by the Saudi Arabian government to return the evacuees.

  14. Broad accommodation of rift-related extension recorded by dyke intrusion in Saudi Arabia

    2010-09-26

    The extensive harrat lava province of Arabia formed during the past 30 million years in response to Red Sea rifting and mantle upwelling. The area was regarded as seismically quiet, but between April and June 2009 a swarm of more than 30,000 earthquakes struck one of the lava fields in the province, Harrat Lunayyir, northwest Saudi Arabia. Concerned that larger damaging earthquakes might occur, the Saudi Arabian government evacuated 40,000 people from the region. Here we use geologic, geodetic and seismic data to show that the earthquake swarm resulted from magmatic dyke intrusion. We document a surface fault rupture that is 8 km long with 91 cm of offset. Surface deformation is best modelled by the shallow intrusion of a north-west trending dyke that is about 10 km long. Seismic waves generated during the earthquakes exhibit overlapping very low- and high-frequency components. We interpret the low frequencies to represent intrusion of magma and the high frequencies to represent fracturing of the crystalline basement rocks. Rather than extension being accommodated entirely by the central Red Sea rift axis, we suggest that the broad deformation observed in Harrat Lunayyir indicates that rift margins can remain as active sites of extension throughout rifting. Our analyses allowed us to forecast the likelihood of a future eruption or large earthquake in the region and informed the decisions made by the Saudi Arabian government to return the evacuees. © 2010 Macmillan Publishers Limited.

    A survey was conducted to determine the status of Lucerne transient streak virus (LTSV) in three high-yielding alfalfa regions in central Saudi Arabia (Riyadh, Qassim, and Hail) during 2014. Three hundred and eight symptomatic alfalfa, and seven Sonchus oleraceus samples were collected. DAS-ELISA indicated that 59 of these samples were positive to LTSV. Two isolates of LTSV from each region were selected for molecular studies. RT-PCR confirmed the presence of LTSV in the selected samples using a specific primer pair. Percentage identity and homology tree comparisons revealed that all Saudi isolates were more closely related to each other but also closely related to the Canadian isolate-JQ782213 (97.1-97.6%) and the New Zealand isolate-U31286 (95.8-97.1%). Comparing Saudi isolates of LTSV with ten other sobemoviruses based on the coat protein gene sequences confirmed the distant relationship between them. Eleven out of fourteen plant species used in host range study were positive to LTSV. This is the first time to document that Trifolium alexandrinum, Nicotiana occidentalis, Chenopodium glaucum, and Lathyrus sativus are new host plant species for LTSV and that N. occidentalis being a good propagative host for it.

  16. Optimization of Broadband Seismic Network in the Kingdom of Saudi Arabia

    KAUST Repository

    Alshuhail, Abdulrahman

    2011-05-01

    Saudi Arabia covers a large portion of the Arabian plate, a region characterized by seismic activity, along complex divergent and convergent plate boundaries. In order to understand these plate boundaries it is essential to optimize the design of the broadband seismic station network to accurately locate earthquakes. In my study, I apply an optimization method to design the broadband station distribution in Saudi Arabia. This method is based on so called D-optimal planning criterion that optimizes the station distribution for locating the hypocenters of earthquakes. Two additional adjustments were implemented: to preferentially acquire direct and refracted wave, and to account for geometric spreading of seismic waves (and thus increases the signal to noise ratio). The method developed in this study for optimizing the geographical location of broadband stations uses the probability of earthquake occurrence and a 1-D velocity model of the region, and minimizes the ellipsoid volume of the earthquake location errors. The algorithm was applied to the current seismic network, operated by the Saudi Geologic Survey (SGS). Based on the results, I am able to make recommendations on, how to expand the existing network. Furthermore, I quantify the efficiency of our method by computing the standard error of epicenter and depth before and after adding the proposed stations.

    Al-Natour, Sahar H

    2014-01-01

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

    Background Internship training offers an important opportunity for personal development and career planning. However, there are many factors affecting the efficiency of training, and the views of interns are rarely considered. The main objective of this study was to explore the views of interns enrolled in Jazan University internship program during the year 2015. Subjects and methods A web-based cross-sectional study was conducted in the Jazan region, Kingdom of Saudi Arabia, during the academic year 2015. To achieve the study goals, an online questionnaire was distributed to all interns (n=85) enrolled in the Jazan University internship program. Results Results revealed that satisfaction with training was more evident in general surgery and pediatrics (76.1%, n=54 and 77.5%, n=55, respectively). Satisfaction was lowest for obstetrics and gynecology programs (45.1%, n=32), while in internal medicine it was 54.9% (n=39). Training in general surgery and pediatrics was rated as excellent by most of the interns (45.8% and 43.1%, respectively). The picture is reversed in obstetrics and gynecology, as 43.1% rated it as average. More than half of the study sample felt that they were well prepared to start the next step in their career at the end of internship (50.7%), while 25.4% felt that they were moderately prepared. Conclusion It is clear that training quality in views of interns is variable across the major specialties, and there are some problems in obstetrics and gynecology training. More studies are needed to explore in-depth dimensions of internship training program in the Kingdom of Saudi Arabia. PMID:28203115

    2015-01-01

    Full Text Available In English as a foreign language (EFL contexts, the absence of authentic language learning situations outside the classroom presents a significant challenge to improving students' English communication skills. Specific obstacles in the learning environment can also result in students’ limited use of English inside the classroom. These issues ultimately affect students’ English speaking capacity. Focusing on the Saudi EFL context, this paper attempted to identify the causes of Saudi students’ low proficiency in English communication and provide some recommendations to address these issues. The most significant findings of the paper were: (1 reforming specific Ministry of Education and Higher Education policies in Saudi Arabia is crucial; (2 the Saudi education system should reinforce the use of contemporary approaches to teaching that emphasise problem solving and critical thinking skills and put students in charge of their own learning; and (3 the ministry should consider converting some Saudi public schools into bilingual schools.

    Chronic viral hepatitis is highly prevalent and creates a substantial burden to healthcare systems globally. The World Health Organization (WHO) estimates that over 350 and 250 million people worldwide are chronic carrier of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection respectively. These two diseases are the cause of significant global mortality and morbidity with approximately 1 million deaths each year attributable to them and their sequelae, liver disease and primary liver cancer. Although the efforts have been met with the long-lasting level of success and holds the promise for large reductions in disease burden in spite of the huge numbers of HBV infected population. The viral hepatitis has also been emerged as a leading public health concern and continues to be major disease burden in the Eastern Mediterranean. The WHO, estimates that approximately 4.3 million persons are infected with HBV in the Region each year. Saudi Arabia has been classified as a country with an intermediate prevalence of HBV showed up to 7% in Saudi children in late 1980s but declined to as low as 0.3% in 1997 since the introduction of universal vaccination of all Saudi children in 1989. In spite of this remarkable decline, the burden of decompensated liver disease secondary to hepatitis B is estimated to increase drastically in the next 40 years as the previously infected children start aging.

The National Guard Health Affairs hospitals. This work discussed the Department of Pharmaceutical Care, and the King Saud Bin Abdulaziz University for Health Sciences College of Pharmacy four initiatives that were planned in 2009–2010 to develop and recruit clinical pharmacists, practitioners, or faculty. Methods: The combined initiatives were aimed at (1 instituting a 4-year clinical skills development career ladder, (2 expanding the National Guard Health Affairs postgraduate residency program, (3 offering scholarships to qualified pharmacy graduates to pursue the PharmD degree and a PGY-1 residency training in the United States, and (4 recruiting non-Saudi clinical pharmacists educated and trained in the United States to ameliorate the current shortage of practitioner. Results: The current number of clinical pharmacists practicing at the National Guard Health Affairs at central region is 24, most of whom are Board Certified by the American Pharmacists Association Board of Pharmacy Specialties. Conclusions: The four initiatives, based on current trends, suggest that 60–65 positions will be added by 2017–2018, barring attrition. Saudi Arabia and many developing countries will continue to experience a shortage in clinical pharmacists due to the high demand for clinical pharmacy services. A multifaceted approach is recommended to address the problem.

    Erythrocytes and progenitor-derived erythroblasts of sickle cell anemia patients from the Eastern Province of Saudi Arabia contain increased fetal hemoglobin and G gamma globin. A distinctive DNA polymorphism haplotype in the beta globin gene cluster (++- +-), tightly coupled to a C----T substitution at position -158 5' to the cap site of the G gamma globin gene, is strongly associated with sickle cell disease in this region. To determine whether the increased fetal hemoglobin production and/or elevated G gamma globin content are tightly linked to this haplotype, we studied 55 members of five Saudi families in which sickle cell disease is present. The results did not suggest a tight linkage of the haplotype to increased fetal hemoglobin production. On the other hand, several sickle trait family members heterozygous for the haplotype had normal fetal hemoglobin production in culture but elevated G gamma to A gamma ratios in peripheral blood. This observation suggests that in this genetic background increased expression of the G gamma globin gene may occur without a measurable increase in total fetal hemoglobin production. The family studies also clearly demonstrate that increased fetal hemoglobin production by erythroid progenitors is dependent on zygosity for the sickle gene in this population. These findings strongly suggest that other factors, such as the products of genes stimulated by hemolytic stress or other genetic determinants associated with the Saudi beta S chromosome, may interact with the -158 C----T substitution and influence gamma globin gene expression in this population.

    Current investigations of the motions of the Arabian and its neighboring plates are primarily based on GPS measurements obtained in the surrounding areas of the Arabian plate, with few stations actually located on the Arabian plate itself in the Kingdom of Saudi Arabia. In order to advance the knowledge of the dynamics of the Arabian plate and its intra-plate deformations, the General Directorate of Military Survey (GDMS), through collaboration with the Institute of Engineering Surveying and Space Geodesy (IESSG), densified the GPS network in Saudi Arabia, covering nearly two thirds of the tectonic plate. Since July 2002, a network of 32 GPS stations has been established at locations of the Saudi Arabia geodetic network. At all of these GPS stations a concrete pillar has been used as the monument and the locations have been selected in order to give the broadest distribution of observing sites. During 2005, 27 additional GPS stations in the Hejaz and Asser Mountains, and the Farasan Islands, all in south-western Saudi Arabia, have been established, for which the past and future campaign GPS measurements will provide valuable data for investigations of crustal deformations close to the plate boundaries between the Nubia, Somalian and Arabian plates. In this presentation we will show results in the form of velocity field and plate motion estimates based on data from at least three campaigns occupying the initial 32 GDMS GPS network stations, but also from a number of IGS stations in the region. Our reference frame is aligned to ITRF2005 and uses approximately 40 IGS reference frame stations located on all major tectonic plates, e.g. Nubia and Somalia, surrounding the Arabian plate. Furthermore, we apply absolute satellite and receiver antenna phase center models together with newly available GPS products from a recent global re-processing effort.

  20. A new case for promoting wastewater reuse in Saudi Arabia: bringing energy into the water equation.

    2012-07-15

    Saudi Arabia is the third-largest per capita water user worldwide and has addressed the disparity between its renewable water resources and domestic demand primarily through desalination and the abstraction of non-renewable groundwater. This study evaluates the potential costs of this approach in the industrial and municipal sectors, exploring economic, energy, and environmental costs (including CO2 emissions and possible coastal impacts). Although the energy intensity of desalination is a global concern, it is particularly urgent to rethink water supply options in Saudi Arabia because the entirety of its natural gas production is consumed domestically, primarily in petrochemical and desalination plants. This burgeoning demand is necessitating the development of more expensive high-sulfur gas resources that could make desalination even pricier. The evolving necessity to conserve non-renewable water and energy resources and mitigate GHG emissions in the region also requires policy makers to weigh in much more considerably the energy and environmental costs of desalination. This paper suggests that in Saudi Arabia, the implementation of increased water conservation and reuse across the oil and natural gas sectors could conserve up to 29% of total industrial water withdrawals at costs recovered over 0-30 years, depending on the specific improvement. This work also indicates that increasing wastewater treatment and reuse in six high-altitude inland cities could save a further $225 million (2009 dollars) and conserve 2% of Saudi Arabia's annual electricity consumption. By these estimates, some anticipated investments in desalination projects could be deferred by improving water efficiency in industry and prioritizing investment in sewage and water distribution networks that would ensure more effective water reclamation and reuse. Simultaneously, such initiatives would conserve non-renewable natural gas resources and could help prevent the lock-in of potentially

    Introduction: Toxoplasma gondii (T. gondii) is an intracellular protozoan that can infect all mammals, who serve as intermediate host. It causes congenital, neurological, eyes complications and mild or asymptomatic infections in humans. Purpose of this study: To investigate not only the prevalence of T. gondii, but also to find out its genotyping using multiple sequential molecular methods to predict exactly the precise genotyping of T. gondii among Saudi pregnant women. Methods: A cross-sectional study was conducted using multi-stage methods. Initial stage involved enrolment of 250 Saudi pregnant women from multi-centre healthcare and community based settings in the capital of Saudi Arabia Riyadh. The second stage was embracement of the laboratory investigation that included Enzyme immunoassay (ELISA), DNA extraction, PCR, nested-PCR assay, and genotyping of the seropositive cases. Results: 203 women agreed to take part in our study with a response rate of 81.2% (203/250). Using ELISA, we found that the prevalence of Toxoplasma gondii IgG and IgM antibodies was 32.5% and 6.4%, respectively. We found that 29 samples (80.6%) were of genotype II; however 7 samples (19.4%) were of genotype III. Conclusion: Defining the population structure of T. gondii from Saudi Arabia has important implications for transmission, immunogenicity, pathogenesis, and in planning preventive strategies. Relationship between such variation in structure and disease manifestation in pregnant women is still difficult to assess due to the role of host immune status and genetic background on the control of infection, and of other parasitic features such as the infecting dose or parasite stage. Our finding of the genotyping of T. gondii might facilitate and inform future studies on comparative genomics and identification of genes that control important biological phenotypes including pathogenesis and transmission among Saudi women.

  2. Climatic controls on the interannual to decadal variability in Saudi Arabian dust activity: Toward the development of a seasonal dust prediction model

    The observed climatic controls on springtime and summertime Saudi Arabian dust activities during 1975-2012 are analyzed, leading to development of a seasonal dust prediction model. According to empirical orthogonal function analysis, dust storm frequency exhibits a dominantly homogeneous pattern across Saudi Arabia, with distinct interannual and decadal variability. The previously identified positive trend in remotely sensed aerosol optical depth since 2000 is shown to be a segment of the decadal oscillation in dust activity, according to long-duration station record. Regression and correlation analyses reveal that the interannual variability in Saudi Arabian dust storm frequency is regulated by springtime rainfall across the Arabian Peninsula and summertime Shamal wind intensity. The key drivers of Saudi Arabian dust storm variability are identified. Winter-to-spring La Niña enhances subsequent spring dust activity by decreasing rainfall across the country's primary dust source region, the Rub' al Khali Desert. A relatively cool tropical Indian Ocean favors frequent summer dust storms by producing an anomalously anticyclonic circulation over the central Arabian Peninsula, which enhances the Shamal wind. Decadal variability in Saudi Arabian dust storm frequency is associated with North African rainfall and Sahel vegetation, which regulate African dust emissions and transport to Saudi Arabia. Mediterranean sea surface temperatures (SSTs) also regulate decadal dust variability, likely through their influence on Sahel rainfall and Shamal intensity. Using antecedent-accumulated rainfall over the Arabian Peninsula and North Africa, and Mediterranean SSTs, as low-frequency predictors, and tropical eastern Pacific and tropical Indian Ocean SSTs as high-frequency predictors, Saudi Arabia's seasonal dust activity is well predicted.

The economic impact of diabetes is estimated in this study, using secondary sources of information provided by Ministry of Health, Ministry of Finance and Central Department of Statistics and Information databases. Results: People diagnosed with diabetes, on average, have medical healthcare expenditures that are ten times higher ($3,686 vs. $380 than what expenditures would be in the absence of diabetes. Over 96% of all medical healthcare expenditures attributed to diabetes are incurred by persons of Saudi nationality, with the remaining 4% incurred by persons of non-Saudi nationality. The population age 45-60 incurs 45% of diabetes-attributed costs, with the remaining population under age 15 incurs 3.8%, age 15-44 incurs 27.5%, and age 60 and above incurs 23.8%. Conclusion: The actual national healthcare burden because of diabetes is likely to exceed the $0.87 billion estimated in this study, because it omits the indirect costs associated with diabetes, such as absenteeism, lost productivity from disease-related absenteeism, unemployment from disease-related disability, lost productivity due to early mortality by disease. The social cost of intangibles such as pain and suffering and care provided by non-paid caregivers as well as healthcare system administrative costs, cost of medications, clinician training programs, and research and infrastructure development is also omitted from this research study. Further studies are needed to confirm the present findings and to improve our

    Full Text Available Communication has a major impact on how customers perceive sellers and their organizations. Especially, the non-verbal communication such as body language, appearance, facial expressions, gestures, proximity, posture, eye contact that can influence positively or negatively the first impression of customers and their experiences in stores. Salespeople in many countries, especially the developing ones, are just telling about their companies’ products because they are unaware of the real role of sellers and the importance of non-verbal communication. In Saudi Arabia, the seller profession has been exclusively for foreign labor until 2006. It is very recently that Saudi workforce enters to the retailing sector as sellers. The non-verbal communication of those sellers has never been evaluated from consumer’s point of view. Therefore, the aim of this paper is to explore the non-verbal communication barriers that customers are facing when dealing with Saudi sellers. After discussing the non-verbal communication skills that sellers must have in the light of the previous academic research and the depth interviews with seven focus groups of Saudi customers, this study found that the Saudi customers were not totally satisfied with the current non-verbal communication skills of Saudi sellers. Therefore, it is strongly recommended to develop the non-verbal communication skills of Saudi sellers by intensive trainings, to distinguish more the appearance of their sellers, especially the female ones, to focus on the time of intervention as well as the proximity to customers.

    Five species of pseudoscorpions are recorded from the southwestern mountains of the Kingdom of Saudi Arabia. Pseudochthonius arabicus Mahnert n. sp. is described as new to science; this genus was previously known only from sub-Saharan Africa and tropical South America and represents the first record of the family Chthoniidae from the Arabian Peninsula. Paratemnoides ellingseni (Beier, 1932), a widespread species in tropical Africa, and Withius piger (Simon, 1878) are added to the faunal list of Saudi Arabia. Minniza monticola Mahnert, 1991 and Rhacochelifer sonyae Mahnert, 1991 are apparently endemic to the southwestern mountains of Saudi Arabia.

    1995-05-01

    A compilation of magnetic data acquired during the past three decades for a region in central Saudi Arabia where Precambrian basement is partly exposed on the Arabian shield and partly concealed by overlying Phanerozoic strata, shows a central sector of conspicuous N-S-trending anomalies, a heterogeneous western sector of short-wavelength, high-intensity anomalies, and an eastern sector of low- to moderate-intensity broad-wavelength anomalies. Anomalies in the western and central sectors correlate with Neoproterozoic metavolcanic, metasedimentary, and intrusive rocks of the Arabian shield and are interpreted as delineating extensions of shield-type rocks down-dip beneath Phanerozoic cover. These rocks constitute terranes making up part of a Neoproterozoic orogenic belt that underlies Northeast Africa and western Arabia and it is proposed that their magnetically indicated easternmost extent marks the concealed eastern edge of the orogenic belt in central Arabia. The flat magnetic signature of the eastern sector, not entirely accounted for as an effect of deep burial, may reflect the presence of a crustal block different in character to the terranes of the orogenic belt and, speculatively, may outline a continental block that, according to some tectonic models of the region, collided with the Neoproterozoic terranes and thereby caused their deformation and tectonic accretion.

    Atmospheric dust significantly influences the climate system, as well as human life in Saudi Arabia. Skillful seasonal prediction of dust activity with climatic variables will help prevent some negative social impacts of dust storms. Yet, the climatic regulators on Saudi Arabian dust activity remain largely unaddressed. Remote sensing and station observations show consistent seasonal cycles in Saudi Arabian dust activity, which peaks in spring and summer. The climatic controls on springtime and summertime Saudi Arabian dust activity during 1975-2010 are studied using observational and reanalysis data. Empirical Orthogonal Function (EOF) of the observed Saudi Arabian dust storm frequency shows a dominant homogeneous pattern across the country, which has distinct interannual and decadal variations, as revealed by the power spectrum. Regression and correlation analyses reveal that Saudi Arabian dust activity is largely tied to precipitation on the Arabian Peninsula in spring and northwesterly (Shamal) wind in summer. On the seasonal-interannual time scale, warm El Niño-Southern Oscillation (ENSO) phase (El Niño) in winter-to-spring inhibits spring dust activity by increasing the precipitation over the Rub'al Khali Desert, a major dust source region on the southern Arabian Peninsula; warm ENSO and warm Indian Ocean Basin Mode (IOBM) in winter-to-spring favor less summer dust activity by producing anomalously low sea-level pressure over eastern north Africa and Arabian Peninsula, which leads to the reduced Shamal wind speed. The decadal variation in dust activity is likely associated with the Atlantic Multidecadal Oscillation (AMO), which impacts Sahel rainfall and North African dust, and likely dust transport to Saudi Arabia. The Pacific Decadal Oscillation (PDO) and tropical Indian Ocean SST also have influence on the decadal variation in Saudi Arabian dust activity, by altering precipitation over the Arabian Peninsula and summer Shamal wind speed. Using eastern

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

    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.

    Background Dental anomalies are not an unusual finding in routine dental examination. The effect of dental anomalies can lead to functional, esthetic and occlusal problems. The Purpose of the study was to determine the prevalence and distribution of selected developmental dental anomalies in Saudi children. Material and Methods The study was based on clinical examination and Panoramic radiographs of children who visited the Pediatric dentistry clinics at King Khalid University College of Dentistry, Saudi Arabia. These patients were examined for dental anomalies in size, shape, number, structure and position. Data collected were entered and analyzed using statistical package for social sciences version. Results Of the 1252 children (638 Boys, 614 girls) examined, 318 subjects (25.39%) presented with selected dental anomalies. The distribution by gender was 175 boys (27.42%) and 143 girls (23.28%). On intergroup comparison, number anomalies was the most common anomaly with Hypodontia (9.7%) being the most common anomaly in Saudi children, followed by hyperdontia (3.5%). The Prevalence of size anomalies were Microdontia (2.6%) and Macrodontia (1.8%). The prevalence of Shape anomalies were Talon cusp (1.4%), Taurodontism (1.4%), Fusion (0.8%).The prevalence of Positional anomalies were Ectopic eruption (2.3%) and Rotation (0.4%). The prevalence of structural anomalies were Amelogenesis imperfecta (0.3%) Dentinogenesis imperfecta (0.1%). Conclusions A significant number of children had dental anomaly with Hypodontia being the most common anomaly and Dentinogenesis imperfecta being the rare anomaly in the study. Early detection and management of these anomalies can avoid potential orthodontic and esthetic problems in a child. Key words:Dental anomalies, children, Saudi Arabia. PMID:27957258

    1992-01-01

    In Saudi Arabia, there were no attempts previously to describe a population based frequency or incidence, particularly so the age adjusted incidence of various CNS tumors. This paper presents the primary CNS tumors from a population based tumor registry over two years period, from January 1987 till December 1988. There was a total of 85 cases representing 5.4% of the total captured cases (1,568 cases of malignant tumors at all sites). The population of the Eastern Province is estimated to be 1.37 million, the Saudis forming 80% of the total population. Out of the 85 cases captured over two years, there were 64 cases diagnosed in indigenous Saudi population forming 75%. The remaining occurred in non-Saudi residents. The male/female ratio in Saudis was 1:1.1 with a slight predominance of the female, while the reverse is true in the non-Saudis (2:1). The total captured cases per annum is 43, making the incidence of primary CNS neoplasms in the Eastern Province of Saudi Arabia 3.1/100,000 of all the population and 2.9/100,000 in Saudi nationals. Comparing this incidence to the international figure, it was clear that it is far less than the incidence reported from North America and Europe, particularly in the Caucasian population, but similar to incidences reported in the Chinese, black Americans, Romanians and Yugoslavians, but certainly less than the Ashkenazi or Safari Jews, and slightly higher than the incidence reported in Japan and Southeast Asia. Malignant brain tumors of various types dominated the primary CNS neoplasms reported over these two years forming 69% of the cases and 52% of the primary brain tumors.

    Full Text Available The main purpose of this research was to gain an understanding of the adoption behavior of mobile computing in Saudi Arabia. In particular, it aimed to acquire new insight into mobile computing trends, specifically in Saudi Arabia, in order to develop hypotheses and formulate precise criteria for mobile computing evaluation. In order to achieve these aims, the researcher created a focus group by recruiting eight participants with solid background knowledge of usability engineering and mobile computing. The focus group proposed a four-phase process: determination, qualification, categorization and evaluation of the mobile computing applications developed by Saudi organizations. During the determination phase, two hundred and twenty seven (n=227 mobile applications were determined as having been developed by organizations in Saudi Arabia. During the qualification phase, one hundred and forty two (n=142 mobile applications were qualified. Within the categorization phase, the experts categorized only the qualified applications into a two-level categorization hierarchy. Finally, in the evaluation phase, the qualified applications were evaluated in terms of purpose, platform, visual appearance, content, organization and usability. The results herein revealed that 43% of the mobile applications in Saudi Arabia were M-Government applications, while 57% were M-Business applications. In addition, the study proposed a sample of thirty six (n=36 applications as having statistical significance from all of the mobile applications in Saudi Arabia.

    Full Text Available To evaluate the prevalence, etiologic factors and therapy of hypertension in actively followed up transplant population in Saudi Arabia; we retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia. These subjects were transplanted between January 1979 and November 1998. The patients were grouped according to the measurement of blood pressure; group 1 (considered normo-tensive: blood pressure below 140/90 mmHg, group2: blood pressure between 140-159/90-99, group 3: blood pressure 160-179/100-109 group 4: equal to or above 180/110. There were 1115 patients′ records included in the study. The mean duration of transplantation was 66.9 ± 50.1 months. According to the level of measured blood pressure, there were 641 (57.5% patients in the normotensive group (group 1, 404 (36.3% patients in the mildly hypertensive group (group 2 64 (5.7% patients in the moderately severe hypertension group (group 3 and only six (0.5% patients in the severe hypertension group (group 4.

    2004-11-01

    Full Text Available Among one of the most far-reaching influences of the Internet, especially from the perspective of business and market models, is the concept and application of eCommerce. Today, this erstwhile ‘experimental’ commerce model has become a standard platform for streamlining business flows and broadening product outreach. This is validated by the significant emphasis by a number of countries in developing robust eCommerce architectures tailored to suit their economical-social systems. An interesting case study in this perspective is the Kingdom of Saudi Arabia, especially given its emphasis on local, regional and religious traditions. Presently, with a tremendous growth rate in Internet connectivity, the Kingdom is actively moving towards large-scale adoption of eCommerce systems. In 2001, a two year project was initiated to study the present influence of Internet on social, educational and business systems within the Kingdom. One of the major aspects was the analysis of user responses collected over the two-year period through a number of surveys, which were designed based on two prominent behavioural models: Theory of Planned Behaviour and Roger’s Theory of Diffusion of Innovations. The consequent analysis of the results was supported and in some cases verified with linear regression models. This paper reports on the consequent findings, which identify factors that may significantly affect the adoption of eCommerce in the Kingdom.

    2015-04-01

    [Purpose] Musculoskeletal disorders are common causes of work-related disability in different professions involving the frequent practice of lifting, stooping, twisting, prolonged sitting, or standing. The dental profession is one such profession. Our aim was to determine the prevalence of work-related musculoskeletal disorders among dental professionals in Saudi Arabia, the factors associated with them, and their consequences and to propose preventive measures for them. [Subjects and Methods] A self-administered online questionnaire was sent to 225 members of the Saudi Dental Association. It included questions on demographic and professional characteristics, general medical history, and history of work-related musculoskeletal disorders before and after joining the dental profession. [Results] The questionnaire was completed by 65% of the respondents. Among them 85% reported that they had developed some pain due to work after joining the dental profession, and 42% reported that they were suffering pain at the time of the survey. Besides lower back, shoulder, and neck regions, the hands, upper back, and other regions like the elbows, buttocks, thighs, leg, and feet were areas in which they pain. [Conclusion] The prevalence of work-related musculoskeletal disorders among dental professionals in Saudi Arabia is high, affecting their daily activities, sometimes even forcing them to change their work setting. Age, gender, specialty of work, work setting, number of contact hours with patients, etc., were all found to be related to their work-related pain. We need to emphasize the role of ergonomics, counseling, proper techniques of patient handling, etc., during the training of dental professionals so that they can work efficiently.

    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.

    Full Text Available Glomerulonephritis (GN is one of the leading causes of end-stage renal disease. A good understanding of its pattern and prevalence as well as exploration of effective therapeutic strategies for protecting the glomerulus, would have tremendous impact on public health. In the Kingdom of Saudi Arabia (KSA, focal and segmental glomerulo sclerosis (FSGS is the commonest type of primary glomerular diseases (PGD encountered in clinical practice. Its prevalence varies from less than 4% in Gizan, in the southern part of KSA, to approximately 35% in Riyadh, central Saudi Arabia. In our experience, the nephrotic syndrome was the commonest mode of presentation of FSGS. Response to corticosteroid therapy is generally poor and the mortality rate is high. Mesangioproliferative GN is the second most common GN constituting up to 25% of PGD in our experience. Other researchers from different parts of the Kingdom, however, have given prevalence rates ranging from 8 to 57.1%. The reported prevalence of Immunoglobulin-A nephropathy (IgAN in KSA ranges from 5.8% to 13.6%. It is more common in the elderly, and men are affected more often than women. In contrast to KSA, IgAN is the commonest PGD in Japan, China, Hong Kong, Singapore and Taiwan. Membranous GN (MGN is less common in KSA than encountered elsewhere, the prevalence ranging from 3.9 to 21.8%. Nephropathy secondary to systemic diseases are also common in KSA. Lupus nephritis (LN accounted for 48.5% of secondary glomerular diseases (SGD with the combination of WHO classes III and IV (aggressive types of LN accounting for 56% of all patients. LN is another disease where differences in racial susceptibility may account for the uneven distribution. Post-streptococcal GN seems to be declining in frequency in KSA, the reported prevalence ranging from 2.7% to 2.9%.

    Full Text Available BACKGROUND: Tuberculosis (TB remains a public health problem in the Kingdom of Saudi Arabia (KSA, which has a very large labour force from high TB endemic countries. Understanding the epidemiological and clinical features of the TB problem, and the TB burden in the immigrant workforce, is necessary for improved planning and implementation of TB services and prevention measures. METHODS: A 10 year retrospective study of all TB cases reported in KSA covering the period 1st January 2000 to 31st December 2009. Data was obtained from TB reporting forms returned to the Ministry of Health. Data were then organised, tabulated and analysed for annual incidence rates by province, nationality, country of origin and gender. RESULTS: There was an annual increase in the number of TB cases registered from 3,284 in 2000 to 3,964 in 2009. Non-Saudis had nearly twice the TB incidence rate compared to Saudis (P = <0.05. All but four provinces (Najran, Riyadh, Makkah, Tabuk showed decreasing TB incidence rates. The highest rates were seen in the 65+ age group. In the 15-24 year age group the incidence rate increased from 15.7/100,000 in 2000 to 20.9/100,00 in 2009 (P = <0.05. The incidence of TB in Saudi males was higher than Saudi females. Conversely, for non-Saudis the TB incidence rates were significantly higher in females compared to males. CONCLUSIONS: Despite significant investments in TB control over 15 years, TB remains an important public health problem in the KSA affecting all age groups, and Saudis and non-Saudis alike. Identification of the major risk factors associated with the persistently high TB rates in workers migrating to KSA is required. Further studies are warranted to delineate whether such patients re-activate latent Mycobacterium tuberculosis (M.tb infection or acquire new M.tb infection after arrival in KSA. Appropriate interventions are required to reduce TB incidence rates as have been implemented by other countries.

  18. Essays on oil and business cycles in Saudi Arabia

    Aba Alkhail, Bandar A.

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

    Sheep and goat pox, peste des petits ruminants and Rift Valley fever are important diseases of small ruminant livestock. Sheep and goat pox, along with peste des petits ruminants, are endemic throughout most of Africa, Asia and the Middle East. Whereas Rift Valley fever is endemic in Africa, outbreaks in the Middle East have been reported over the past decade, including the Arabian Peninsula. Saudi Arabia is a major importer of livestock, and understanding the prevalence of these viral infections would be useful for disease control. In this study, sera from sheep and goats were collected from 3 regions in Saudi Arabia. They were evaluated for antibodies specific to sheep and goat pox, peste des petits ruminants and Rift Valley fever by virus neutralization assays. To the best of our knowledge, this is the first study to evaluate the seroprevalence of these viruses in sheep and goats.

    Model. The empirical models then are applied to sets of data from 1980 to 2002 for Saudi Arabia, Kuwait, Venezuela and Norway. The rationale of including other oil-exporting countries is to distinguish whether the shocks are country-specific, regional-specific, or global. Two sets of shocks are considered: international shocks and domestic shocks. Three types of international shocks are chosen: commodity-price (oil price) shock, international financial (interest rate) shock, and international real (output) shock. In addition, five domestic shocks which are non-oil output shock, oil production shock, price level shock, monetary shock, and exchange rate shock. The findings reached in the study demonstrate that the international shocks are responsible for a high proportion of fluctuations in the economic activity in Saudi Arabia. Most importantly, the international financial shocks represented by the US interest rate and oil price shocks are the major sources of fluctuations in the Saudi Arabian economy. Domestically, the economy is mostly affected by the oil production and the non-oil output shocks for Saudi Arabia. These results emphasize that the Saudi Arabia's role in the international oil market and its fixed exchange rate regime have significant implications on the domestic economy. Thus, special considerations should be placed on designing the appropriate policies to lessen the dependency on the oil sector and strengthen the role of private sector to diversify the economic base, and provide an independent sound monetary policy to steer the economy from the fluctuations in the global economy.

    We investigate the lithospheric shear-wave velocity structure of Saudi Arabia by conducting H-κ stacking analysis and jointly inverting teleseismic P-receiver functions and fundamental-mode Rayleigh wave group velocities at 56 broadband stations deployed by the Saudi Geological Survey (SGS). The study region, the Arabian plate, is traditionally divided into the western Arabian shield and the eastern Arabian platform: The Arabian shield itself is a complicated mélange of crustal material, composed of several Proterozoic terrains separated by ophiolite-bearing suture zones and dotted by outcropping Cenozoic volcanic rocks (locally known as harrats). The Arabian platform is primarily covered by 8 to 10 km of Paleozoic, Mesozoic and Cenozoic sedimentary rocks. Our results reveal high Vp/Vs ratios in the region of Harrat Lunayyir, which are interpreted as solidified magma intrusions from old magmatic episodes in the shield. Our results also indicate slow velocities and large upper mantle lid temperatures below the southern and northern tips of the Arabian shield, when compared with the values obtained for the central shield. We argue that our inferred patterns of lid velocity and temperature are due to heating by thermal conduction from the Afar plume (and, possibly, the Jordan plume), and that volcanism in western Arabia may result from small-scale adiabatic ascent of magma diapirs.

    Life in arid regions and, in particular, hot deserts is often limited due to their harsh environmental conditions, such as large temperature fluctuations and low amounts of water. These extreme environments can influence the microbial community present on the surface sands and any rhizosphere members surrounding desert plant roots. The Jizan desert area, located in Saudi Arabia, supports particular vegetation that grows in the large sandy flat terrain. We examined five different samples, four from the rhizosphere of pioneer plants plus a surface sand sample, and used pyrosequencing of PCR-amplified V1-V3 regions of 16S rDNA genes from total extracted DNA to reveal and compare the bacterial population diversity of the samples. The results showed a total of 3,530 OTUs in the five samples, calculated using ≥ 97% sequence similarity levels. The Chao1 estimation of the bacterial diversity fluctuated from 637 to 2,026 OTUs for a given sample. The most abundant members found in the samples belong to the Bacteroidetes, Firmicutes and Proteobacteria phyla. This work shows that the Jizan desert area of Saudi Arabia can contain a diverse bacterial community on the sand and surrounding the roots of pioneer desert plants. It also shows that desert sand microbiomes can vary depending on conditions, with broad implications for sandstone monument bacterial communities

    Full Text Available Universities are paramount change drivers in bringing about a culture of sustainability in society by setting themselves up as models and nurseries for sustainable development. Thus, assessment of sustainability integration within universities is key to their impact on sustainable development. This study conducted an assessment of different public sector universities of Saudi Arabia based on five components: (i Teaching and Curriculum; (ii Research and Scholarship; (iii Campus Operations; (iv Management and Community; and (v Financial Management. The sustainability assessment questionnaire (SAQ was utilized as a tool to discern the component-wise sustainability assessment for Saudi universities. The outcomes of the survey reveal that, in stark contrast with the universities of the developed world, offerings of sustainability relevant academic courses in Saudi Arabia are still lacking. Most Saudi universities still need to integrate research and scholarship in the area of sustainability; sustainable-campus operations in the current scenario are not sufficient. The results also reveal that sustainability-related projects are not prioritized within universities and sustainable financial management practices are not significant. This article concludes by proposing some recommendations emphasizing the importance of adopting sustainability practices in Saudi universities.

    Aims: This study aims to explore the criteria used by graduate students while selecting a career as orthodontists and their future aspirations. Materials and Methods: A list of Saudi Board of Orthodontics (SB-Ortho) residents was obtained from the Central and Western regions of the Kingdom and all orthodontic residents (excluding the 1st year residents) were invited to participate in this survey. Permission to contact the orthodontic residents was obtained from the respective program directors. The final study sample composed of 36 orthodontic residents. Results: About 39% of residents chose orthodontic specialty after graduation, nearly 33% selected the career during the undergraduate education while the rest chose the specialty at other stages. Approximately, 67% of the residents chose orthodontic specialty because it is intellectual challenging. Around 25% of residents choose orthodontic to improve their earning and 39% join orthodontic for job prestige. Around 50% of orthodontic Saudi residents planned to use self-ligating brackets; 63.9% planned to use invisalign; 86.1% plan to use temporary anchorage devices. About 72% of residents plan to use a cone-beam computerized tomography; 89% plan to use a digital imaging program; 39% plan to use indirect bonding; and 28% plan to use lingual orthodontics. More than half of the residents showed interest to participate in the research and about a quarter of them were willing to work in small cities. Conclusions: Most of the orthodontic residents in Saudi Arabia take up this specialty as they felt that it was intellectually challenging. The SB-Ortho program adequately prepares the residents in all the modern aspects of the specialty. PMID:24987645

    Objectives: To assess health care services provided to type 1 and type 2 diabetic patients and diabetes health care expenditure in the Kingdom of Saudi Arabia (KSA). Methods: This study was part of a nationwide, household, population based cross-sectional survey conducted at the University Diabetes Center, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia between January 2007 and December 2009 covering 13 administrative regions of the Kingdom. Using patients’ interview questionnaires, health care services data were collected by trained staff. Results: A total of 5,983 diabetic patients were chosen to assess health care services and expenditure. Approximately 92.2% of health services were governmental and the remaining 7.8% were in private services. The mean annual number of visits to physicians was 6.5±3.9 and laboratories was 5.1±3.9. Diabetic patients required one admission every 3 years with a mean admission duration of 13.3±28.3 days. General practitioners managed 85.9% of diabetic cases alone, or shared with internists and/or endocrinologists. Health care expenditure was governmental in 90% of cases, while it was personal in 7.7% or based on insurance payment in 2.3%. Conclusion: Health services and its expenditure provided to diabetic citizens in Saudi Arabia are mainly governmental. Empowerment of the role of both the private sector and health insurance system is badly needed, aside from implementing proper management guidelines to deliver good services at different levels.

    This study describes a seroepidemiological survey on Rift Valley fever (RVF) among small ruminants and their close human contacts in Makkah, Saudi Arabia. A total of 500 small ruminants (126 local, 374 imported) were randomly selected from the sacrifice livestock yards of Al-Kaakiah slaughterhouse, in the holy city of Makkah, during the pilgrimage season 1432 H (4-9 November 2011). In addition, blood samples were collected from 100 local workers in close contact with the animals at the slaughterhouse. An RVF competition multi-species enzyme-linked immunosorbent assay (ELISA) detecting anti-RVF virus immunoglobulin G (IgG)/ immunoglobulin M (IgM) antibodies and an RVF IgM-specific ELISA were used for serological investigations. In total, 84 (16.8%) of the 500 sacrificial sheep and goats tested seropositive in the competition ELISA but no IgM antibodies were detected in the IgM-specific assay. All seropositive samples, comprising 17.91% of the imported animals and 13.49% of the local ones, were therefore designated positive for anti-RVF virus IgG antibody. Among the local personnel working in close contact with the animals, 9% tested seropositive in the RVF competition ELISA. The study indicates that two factors may increase the likelihood of an RVF outbreak among sacrificial animals and pilgrims: i) the large-scale importation of small ruminants into Saudi Arabia from the Horn of Africa shortly before the pilgrimage season, and ii) the movement of animals within Saudi Arabia, from the RVF-endemic south-western area (Jizan region) to the Makkah region, particularly in the few weeks before the pilgrimage season. From these findings, it is recommended that i) all regulations concerning the import of animals into Saudi Arabia from Africa should be rigorously applied, particularly the RVF vaccination of all ruminants destined for export at least two weeks before exportation, and ii) the movement of animals from the RVF-endemic south-western area (Jizan region) of Saudi

    In Saudi Arabia, local interpretations of Islamic laws and social norms have a negative impact on the health and well-being of women. The objective of this literature review was to discuss gender inequity in Saudi Arabia and its relation to public health. Despite the scarcity of recent statistics and information regarding gender inequity in Saudi Arabia, this review is an attempt to explore this sensitive issue in this country. Women's roles and rights in Saudi society were examined, including education, marriage, polygamy, fertility, job opportunities, car driving and identification cards. Further research to assess knowledge, attitudes and practices towards health care of Saudi men and women is recommended.

  11. Growth and Maturation of Plectropomus spp. in the Saudi Arabian Red Sea

    2011-05-01

    Two species of plectropomid grouper (Plectropomus areolatus and P. pessuliferus) are found in the Red Sea. In Saudi Arabia these are the most valuable fishes by weight, averaging wholesale prices around US $15 per kilogram (personal observation). Over the past two decades, the number of fishing vessels in the Saudi Arabian Red Sea has tripled. Despite this increase in fishing effort Saudi Arabia has not implemented any marine resource management for Red Sea fisheries. Little biological data are currently available to inform managers. The research presented here addresses knowledge gaps on the growth pattern, longevity and sexual ontogeny of Plectropomus spp. in the Red Sea. Collections of each species were established by purchasing landed individuals from fishermen and fish markets distributed evenly between three latitudinal regions around the country. The total length of each fish was measured to the nearest millimeter. Age was estimated by enumerating annual bands visualized in transverse sections of sagittal otoliths. Sexual stage was determined via histological examination of gonadal tissue. Plots of total length versus age were fitted with reparameterized von Bertalanffy growth functions constrained to a size-at-settlement estimate of 20 mm. P. pessuliferus achieved a larger size (maximum 960 mm) and an older age (maximum 19 years) than P. areolatus (maximum size 570 mm, maximum age 9 years). While no regional patterns were found for P. pesuliferus, likelihood ratio tests revealed regional differences in growth pattern for P. areolatus, finding an increasing mean age, increasing mean length, and decreasing growth rate with decreasing latitude. In addition, males of P. areolatus were more abundant in the Southern region. These findings contradict existing theories about the effects of latitudinal temperature gradients on life history. It is hypothesized that the broader continental shelf in the Southern region may be providing a haven for these species in the

    Patient education is one of the main factors of patient therapeutic plan and without it, the patient may not benefit from his/her medications. Several studies showed the effectiveness of educating patients about their disease(s) and their medication(s) which ultimately enhance their quality of life especially in chronic diseases such as diabetes mellitus and hypertension. Concept of patient education is well known and understood in the Western countries while in the Kingdom of Saudi Arabia it is not well established despite some efforts made by few big hospitals. In Saudi Arabia, different stakeholders such as hospitals, pharmaceutical companies, healthcare professionals, health societies and association and governmental agencies do not do their job as patient education. Aim of this paper was to throw some light about the current situation in Saudi Arabia.

    Full Text Available Rabies is endemic in animals in the Arabian Peninsula. Although Saudi Arabia is the largest country in the Peninsula, little has been published about the rabies situation in the country. A total of 11 069 animal bites to humans were reported during 2007–2009, and 40 animals suspected of rabies were examined for rabies infection from 2005 through 2010. Results suggest that animal-related injuries in Saudi Arabia remain a public health problem, with feral dogs accounting for the majority of bites to humans and for the majority of animals found to be rabid. Over the last 10 years, no confirmed human rabies case has been reported. More detailed information about the epidemiology of animal bites and that of animal rabies in Saudi Arabia would be of great interest, notably to provide a basis on which vaccination recommendations could be made for the numerous international travellers visiting the country.

On the other hand, the following food stuffs were found to be protective: seafood, fruit, and dairy products. Comprehensive school educational programs for both children and their parents should be adopted to prevent the use of wood in cooking and heating, to ensure that house pets are properly cared for, and to encourage proper dietary habits. Physicians should be informed of the patterns of allergens in order to improve asthma diagnosis and management.

However, only few studies have been conducted in this area in developing countries, particularly in Saudi Arabia. This research is carried out in an attempt to address this gap, exploring the impact of applying TQM practices on hospital performance in the Saudi Ministry of Health hospitals. The study has included 4 hospitals in Tabuk Region, namely, King Khaled Hospital, King Fahad Hospital, Maternity and Children Hospital, and Hagel General Hospital. The data collection was done by the researcher when 400 questionnaires were distributed using a convenient sampling technique to access the required data. The response rate was 67.25% of the total questionnaires distributed. The TQM practices used in the study were as follows: leadership, employee management, information analysis, training, customer focus, continuous improvement, process management, and supplier management. The findings of the research show a significant positive correlation between the 8 practices of TQM and hospital performance with a correlation coefficient r value of 0.9 (P = .0001). The study also reveals that Saudi hospitals are facing difficulties in engaging the clinical staff in their quality initiative. Moreover, our findings show that accredited hospitals have significantly applied TQM practices more than unaccredited hospitals.

    Background: Many international studies have been conducted to assess the knowledge, attitudes and practices (KAP) of the public toward sun exposure and sun-protection measures. However, there are scarce data on these factors from the Middle East. Objectives: This study aimed to explore the KAP of the public toward sun exposure and sun-protection measures among Saudis. Methods: A cross-sectional survey using a specially designed questionnaire was conducted on a stratified random sample of the general population in the five geographical regions of Saudi Arabia (central, eastern, northern, southern, and western). Data were collected between October 2010 and March 2011. Multiple logistic regressions were applied to relate the use of sunscreen and skin cancer awareness with various socio-demographic variables. Results: The questionnaire was distributed to 2900 Saudis. A total of 2622 questionnaires were completed, returned, and included in the data analysis, corresponding to a response rate of 90.4%. The mean (SD) age of respondents was 27.8 ± 9.7 years. Fifty percent (1301/1601) of the respondents were males. Fifty-five percent (1406/2544) were aware of the association between sun exposure and skin cancer. Female, young and student respondents were more likely to be aware of the connection between sun exposure and skin cancer (p Protective clothes were the most commonly used sun protection measure as reported by more than 90% of our participants. Conclusion: This study has shown that sun awareness and protection are generally inadequate in the Saudi population and suggests the need for health education programs.

    A rapid rise in the number of tobacco users in Saudi Arabia has occurred in the past decade, particularly among the youth. This study identified socio-cultural determinants of tobacco use and explored possible approaches to prevent adolescents' tobacco use in Saudi Arabia. A cross-sectional survey was administered using a self-administered questionnaire for collecting information on risk and protective factors for tobacco use among middle school students. School selection was stratified by region, gender, and type (public or private). Of 1,186 7-9th grade students, 1,019 questionnaires were analyzed. Risk factors affecting tobacco use included all important others' perceptions; mother, sister, friend, teacher and important person's tobacco use; pressure to use tobacco from brother, sister, friend and important persons; easy access to tobacco and frequent skipping of classes. Protective factors for tobacco use included family's perception; friend, teacher and important person's tobacco use; parents' help; support from family, friends, and teachers; accessibility to tobacco; school performance and family income, father's education, and district of residence. The findings of this study show clear gender differences in social influences and attitudes towards tobacco use. Religious beliefs and access to tobacco products were significantly associated with attitudes towards tobacco use and future intention of use. Developing and implementing effective gender specific school-based tobacco prevention programs, strict reinforcement of tobacco control policies, and a focus on the overall social context of tobacco use are crucial for developing successful long-term tobacco prevention programs for adolescents.

    Objective:To determine the current seroprevalence of antibodies against hepatitis A virus in selected group of children aged 1-6 years in Northern borders region, Saudi Arabia, and to identify risk factors for infection.Methods: A cross-sectional sero-epidemiological study of 950 children who attended 10 randomly selected primary health care centers (5 urban and 5 rural) was done. Parents of all children were subjected to a questionnaire including sociodemographic and housing environmental data. The determination of anti-HAV antibodies was carried out by ELISA-test.Results:The prevalence of HAV-IgG was 33.8% overall, 35.5% among males and 32.0% among females with no statistically significant difference. Multivariate logistic regression analysis revealed that increasing age, rural residence, non Saudi nationality, and non availability of safe municipal water source were the most important independent predictors for HAV seropositivity in the studied children.Conclusions:There is a clear decrease in hepatitis A prevalence in the studied children particularly in urban areas and indicates that a transition may be underway to intermediate endemicity and possible shift of the risk to the adult age with increased morbidity. So, we recommend including Hepatitis A in the schedule of routine childhood vaccinations.

    Objective: To establish molecular characterization of Plasmodium falciparum field isolates in Jazan Area of Saudi Arabia measured with highly polymorphic genetic marker, i.e. the merozoite surface protein 2(MSP 2).Methods: Blood samples were collected from 128 clinically suspected patients attending both Jazan and Sabia hospitals, Kingdom of Saudi Arabia. Both hospitals reflected urban and rural settings respectively. Analysis of central polymorphic region of MSP 2(3D7 and FC27 allelic families) was performed using nested PCR for malaria patients.Results: For MSP 2 allelic families of Plasmodium falciparum, 16 cases(53.3%) carried FC27 type and 14 cases(46.7%) carried 3D7 type, whereas no malaria cases harbored both allelic types. The present study showed that in urban area, 80% of FC27 fragments were 500 bp while in rural area it was 45.5%(P = 0.08). The FC27 400 bp allele was more prevalent in patients from rural than those from the urban area(P = 0.08). The most prevalent infecting 3D7 allele was the 3D7 300 bp in both areas. In the present study, there were no multiple infections.Conclusions: The limited genetic diversity which was observed in Jazan(considered as an endemic area) may be attributed to the small sample size or sustained malaria control program.

    Full Text Available The present study was the first attempt to survey the diversity of fish zoonotic parasites in the southern region of Saudi Arabia, particularly the Najran area, from October 2012 to October 2013. Approximately 163 fish representing seven species (two of freshwater fish and five of marine fish were examined for fish-borne trematode metacercariae using the compression technique, and for zoonotic nematode larvae. Adult flukes were obtained from cats experimentally infected with the metacercariae on day 25 post-infection The prevalence of each parasite species was recorded. The parasites found belonged to two taxa: Digenea (Heterophyes heterophyes and Haplorchis pumilio in muscle tissue; and nematodes (larvae of Capillaria sp. in the digestive tract. The morphological characteristics of the fish-borne trematode metacercariae and their experimentally obtained adults were described. This is the first report of these parasites in fish in Saudi Arabia. Moreover, Myripristis murdjan presented higher prevalence of Capillaria sp. infection (22.7%, while Haplorchis pumilio was the dominant metacercarial species (7.9%. Although the number of documented cases continues to increase, the overall risk of human infection is slight. The increasing exploitation of the marine environment by humans and the tendency to reduce cooking times when preparing seafood products both increase the chances of becoming infected with these parasites. Furthermore, our results indicate that certain fish production systems are at risk of presenting fish zoonotic parasites, and that control approaches will benefit from understanding these risk factors.

    The purpose of this study is to use geophysical imaging methods to identify the conjectured location of the ‘Qadimah fault’ near the ‘King Abdullah Economic City’, Saudi Arabia. Towards this goal, 2-D resistivity and seismic surveys were conducted at two different locations, site 1 and site 2, along the proposed trace of the ‘Qadimah fault’. Three processing techniques were used to validate the fault (i) 2-D travel time tomography, (ii) resistivity imaging, and (iii) reflection trim stacking. The refraction traveltime tomograms at site 1 and site 2 both show low-velocity zones (LVZ’s) next to the conjectured fault trace. These LVZ’s are interpreted as colluvial wedges that are often observed on the downthrown side of normal faults. The resistivity tomograms are consistent with this interpretation in that there is a significant change in resistivity values along the conjectured fault trace. Processing the reflection data did not clearly reveal the existence of a fault, and is partly due to the sub-optimal design of the reflection experiment. Overall, the results of this study strongly, but not definitively, suggest the existence of the Qadimah fault in the ‘King Abdullah Economic City’ region of Saudi Arabia.

    A preliminary survey of Saudi Arabian Alcyonacea is presented, which combines classical taxonomy, multilocus molecular barcodes, and in situ photographs. We explored 14 locations along the west coast of the Kingdom of Saudi Arabia to assess the regional taxonomic diversity of non-gorgonian alcyonaceans. We collected samples from a total of 74 colonies, distributed among four families: 18 colonies of Alcyoniidae, 14 of Nephtheidae, 9 of Tubiporidae, and 33 of Xeniidae. We sequenced the octocorals using multiple nuclear [ribosomal Internal Transcribed Spacers (ITS) and ATP Synthetase Subunit α (ATPSα)] and mitochondrial [MutS homolog (mtMutS) and Cytochrome C Oxidase subunit one (COI)] loci, providing molecular barcodes which will: (1) allow direct comparison of biodiversity from this location to others for which molecular data are available, and (2) facilitate future identifications of these taxa. Finally, this preliminary phylogeny of sampled taxa provides insights on the resolution of mitochondrial versus nuclear loci, and highlights octocoral taxa that require further taxonomic attention. © 2013 Senckenberg Gesellschaft für Naturforschung and Springer-Verlag Berlin Heidelberg.

    Subjective perceptions and perceived needs for dental care in a population can provide important information for policy-makers. This study aimed to assess self-perceived personal oral health status among the Saudi Arabia population who could be accessed through social media. A pre-tested questionnaire for completion online was designed to assess self-perceived oral health via 13 items in 4 domains with weighted scores from 1-3. The questionnaire was uploaded to the Internet and the link to it was made available through popular social networking sites in Saudi Arabia. With respondents recruited by snowball methods a total of 4618 people (57.2% males, 42.8% females) completed the questionnaire. The total mean score for the participants was 23.0 (SD 5.0) (scale range 13-39). Self-perceived oral health was rated as poor by 24.2% of respondents, average by 50.6% and good by 25.2%. Educational level, age and region but not sex were significantly associated with self-perceived oral health.

  7. Nationalization Scheme (Nitaqat in Saudi Arabia and the Condition of Filipino Migrant Workers

    2014-11-01

    Full Text Available The Philippines is one of few countries in the developing world that heavily relied on exporting its laborers to sustain its economic growth. Despite attempts by previous administrations to minimize sending Filipino workers abroad by improving working condition at home so that working abroad would no longer be compulsory but optional, many Filipinos continue to leave the country hoping to alleviate their families from poverty. This idea of working abroad has several implications for migrant workers especially in regions where labor policies are not clearly laid down and that rights and welfare of migrant workers are not protected. This paper seeks to elucidate the conditions of Overseas Filipinos Workers (OFWs in Saudi Arabia which strictly implemented “Saudization”2 policy since 2011. In particular, the paper tries to address the following questions: What does “Saudization” (nitaqat mean from Filipinos’ perspectives?; Who are affected by this policy and Why have OFWs been affected by such policy?; How did undocumented or illegal OFWs survive in previous years?; What policies they have implemented to counter it? This paper is centered on its main thesis that Saudi Nationalization policy, which is centered on solving socio-economic problems facing the young and unemployed population in several Gulf countries, has been the driver for these governments to strictly implement such a law and that many migrant workers including Filipinos working on specific areas together with undocumented ones are gravely affected.

    Full Text Available Abstract Background Epilepsy is genetically complex but common brain disorder of the world affecting millions of people with almost of all age groups. Novel Copy number variations (CNVs are considered as important reason for the numerous neurodevelopmental disorders along with intellectual disability and epilepsy. DNA array based studies contribute to explain a more severe clinical presentation of the disease but interoperation of many detected CNVs are still challenging. Results In order to study novel CNVs with epilepsy related genes in Saudi family with six affected and two normal individuals with several forms of epileptic seizures, intellectual disability (ID, and minor dysmorphism, we performed the high density whole genome Agilent sure print G3 Hmn CGH 2x 400 K array-CGH chips analysis. Our results showed de novo deletions, duplications and deletion plus duplication on differential chromosomal regions in the affected individuals that were not shown in the normal fathe and normal kids by using Agilent CytoGenomics 3.0.6.6 softwear. Copy number gain were observed in the chromosome 1, 16 and 22 with LCE3C, HPR, GSTT2, GSTTP2, DDT and DDTL genes respectively whereas the deletions observed in the chromosomal regions 8p23-p21 (4303127–4337759 and the potential gene in this region is CSMD1 (OMIM: 612279. Moreover, the array CGH results deletions and duplication were also validated by using primer design of deleted regions utilizing the flanked SNPs using simple PCR and also by using quantitative real time PCR. Conclusions We found some of the de novo deletions and duplication in our study in Saudi family with intellectual disability and epilepsy. Our results suggest that array-CGH should be used as a first line of genetic test for epilepsy except there is a strong indication for a monogenic syndrome. The advanced high through put array-CGH technique used in this study aim to collect the data base and to identify new mechanisms describing

    Full Text Available Abstract Background Bullying and sexual harassment of medical students by their teachers appears to be widespread phenomenon. However, nothing is published about its prevalence in conservative countries such as Saudi Arabia. This survey aims to ascertain the extent of these mistreatments among students in a Saudi medical school. Findings A cross-sectional questionnaire survey was conducted on a group of 542 clinical years’ medical students in a Saudi medical school to explore students' perceptions of their educational environment including exposure to different kinds of bullying. Bullying was defined as “a “persistent behaviour against a medical student that is intimidating, degrading, offensive or malicious and undermines the confidence and self- esteem of the recipient”. Results revealed that more than one quarter (28.0% of the surveyed students reported exposure to some sort of bullying during their clinical. Ninety percent of the reported insults were verbal, 6% sexual and 4% physical. Males were more exposed but difference was not statistically significant. Conclusions Bullying among Saudi medical students is an existing problem. A policy against bullying and harassment should be adopted in all of medical colleges to monitor this phenomenon and support students who have been bullied.

However, current national estimates on fruit and vegetable consumption in the Kingdom of Saudi Arabia (KSA are nonexistent. We conducted a large household survey to inform the Saudi Ministry of Health (MOH on a major modifiable risk factor: daily consumption of fruits and vegetables. Methods: The Saudi Health Interview Survey is a national multistage survey of individuals aged 15 years or older. It includes questions on sociodemographic characteristics, tobacco consumption, diet, physical activity, health care utilization, different health-related behaviors, and self-reported chronic conditions. We used a backward elimination multivariate logistic regression model to measure association between the Centers for Disease Control and Prevention (CDC-recommended daily consumption of fruits and vegetables and different factors. Results: Between April and June 2013, a total of 10,735 participants completed the survey. Overall, 2.6% of Saudis aged 15 years or older met the CDC guidelines for daily consumption of fruits and vegetables. The likelihood of meeting the CDC guidelines increased with age; among women; among persons who graduated from elementary or high school or had a higher education; among residents of Makkah, Al Sharqia, Ha’il, or Jizan; among those who consumed at least two servings of meat or chicken per day; among those who visited a health care facility for a routine medical exam

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

    Changing pattern of Saudi Arabia's oil exports Saudi Arabia (hereinafter referred to as Saudi) long time ranks No. one of world oil production and lost the title only in 2009 and 2010 due to cutting output which is slightly lower than the Russian output. It is predicted that global annual oil output in the next 10 years will be more than 4 billion tons, during which Saudi annual oil output will be up to 540-550 million tons, accounting for about 14 percent of global annual oil output. Saudi's 2005 oil exports of about 360 million tons accounted for 17.78 percent of the global oil exports, and 42.66% of the Middle East. Over the next 10 years, it is expected Saudi oil exports will reach 380-400 tons. Saudi plenty of spare oil production capacity and enhanced oil recovery will increase its remaining recoverable oil reserve,

    Sickle cell disease (SCD) is an autosomal recessive inherited hemoglobinopathy, characterized by chronic hemolysis and recurrent vaso-occlusive crisis (VOC). This study investigates changes in leucocyte subsets and the relationship between cell adhesion molecule expression and disease manifestations in patients during steady state and acute VOC. We compared soluble E-selectin and P-selectin levels in 84 SCD patients, in steady state and during VOC to 84 healthy controls. Using immunophenotyping, we also compared lymphocyte subsets in these three groups. Further, we compared E-selectin and P-selectin levels in patients of Saudi ethnicity to non-Saudi patients, in all three groups. Lymphocyte subsets showed high percentages of total T lymphocytes, T helper and suppressor lymphocytes, B lymphocytes as well as NK cells in patients with SCD during steady state, while B lymphocytes and NK cells were significantly higher during acute VOC crisis. High levels of both soluble E-selectin (sE-selectin) and soluble P-selectin (sP-selectin) markers were demonstrated in the serum of patients with SCD during both steady state and acute VOC. Levels of selectins were significantly higher in acute VOC. The immunophenotypic expression of L-selectin, on leucocytes, was high in SCD both during steady state and during acute VOC in comparison to normal control subjects. There was no significant difference in all three study groups between Saudi and non-Saudi patients. These findings suggest that patients with SCD have increased expression of adhesion molecules: E-selectin and P-selectin, which play an important role in the pathogenesis of VOC. Despite the distinct phenotype of Saudi patients with SCD, there was no significant difference in levels of soluble E-selectin and soluble P-selectin between Saudi and non-Saudi patients in all three groups. While sickle cell disease is a well-recognized state of chronic inflammation, the role of specific adhesion molecules is steadily unraveling

    2015-11-20

    Coral reef communities between 26.8°N and 18.6°N latitude in the Saudi Arabian Red Sea were surveyed to provide baseline data and an assessment of fine-scale biogeography of communities in this region. Forty reefs along 1100 km of coastline were surveyed using depth-stratified visual transects of fish and benthic communities. Fish abundance and benthic cover data were analyzed using multivariate approaches to investigate whether coral reef communities differed with latitude. A total of 215 fish species and 90 benthic categories were recorded on the surveys. There were no significant differences among locations in fish abundance, species richness, or among several diversity indices. Despite known environmental gradients within the Red Sea, the communities remained surprisingly similar. The communities do, however, exhibit subtle changes across this span of reefs that likely reflect the constrained distributions of several species of reef fish and benthic fauna.

    2016-03-18

    © 2016 EEGS. Geotechnical parameters were used to determine subsurface rock quality for construction purposes. We summarize the mathematical relationships used to calculate the geotechnical parameters from P- and S-wave velocities and density values. These relationships are applied to two field examples; the first is a regional seismic study in Egypt and the second is a 2-D seismic profile recorded in Saudi Arabia. Results from both field examples are used to determine the subsurface rock quality and locate zones that should be avoided during construction. We suggest combining all geotechnical parameters into one map using a normalized-weighted relation, which helps to locate the zones with high versus low rock quality for engineering purposes.

    Full Text Available Aquagenic Wrinkling of the Palms (AWP is a rare dermatologic disease. It was first described four decades ago as a potential test for Cystic Fibrosis (CF by detecting “skin wrinkling” in response to water immersion. We are reporting two cases of AWP diagnosed at Derma Clinic, Riyadh, Saudi Arabia. The first case was a 9-year old girl and the second case was a 17-year adolescent male. The second case was associated with palmer hyperhidrosis. Both patients denied any medication use. Additionally, signs and symptoms suggesting CF were lacking. Local dermatologists should be aware of rare conditions such as AWP and lack of previous reports from the region may indicate under-reporting rather than lack of cases.

    Measurements of 14 polycyclic aromatic hydrocarbons (PAH) have been made in Jeddah, Saudi Arabia, with a view to establishing the concentrations in this major city, and quantifying the contributions of major sources. Particulate and vapour forms have been sampled and analysed separately. The concentrations are compared to measurements from other sites in the Middle Eastern region and are towards the lower end of the range, being far lower than concentrations reported from Riyadh (Saudi Arabia), Assiut (Egypt) and Tehran (Iran) but broadly similar to those measured in Damascus (Syria) and higher than those measured in Kuwait. The partitioning between vapour and particle phases is similar to that in data from Egypt and China, but with many compounds showing a higher particle-associated percentage than in Birmingham (UK) possibly reflecting a higher concentration of airborne particulate matter in the former countries. Concentrations in Jeddah were significantly higher at a site close to the oil refinery and a site close to a major ring road than at a suburban site to the north of the city. Application of positive matrix factorisation to the pooled data elicited three factors accounting respectively for 17%, 33% and 50% of the measured sum of PAH and these are interpreted as arising from gasoline vehicles, industrial sources, particularly the oil refinery, and to diesel/fuel oil combustion. - Highlights: • Measurements of 14 PAH compounds in vapour and particulate phases at three sites. • Comparison of concentrations across Jeddah and Middle Eastern regions. • Application of positive matrix factorisation to identify possible sources.

    Full Text Available Background/Aim: Morbidly obese patients have a high prevalence of fatty liver disease and its serious complications, and high prevalence of abnormal liver function tests (LFT. The LFT can give a clue to the liver damage and correlate with activity. We aim to study the pattern of LFT in morbidly obese Saudi patients undergoing bariatric surgery in Eastern region. Patients and Methods: Medical records of patients undergoing bariatric surgery were reviewed. Demographic data, comorbid conditions, and medications taken were recorded. Intraoperative liver appearance was noted. Patients with alcohol intake or without LFT were excluded. Results: Out of 113 patients, 15 patients were excluded, and of the remaining 98 patients analyzed, 58.2% were females. Mean age was 33.1 ± 8.87 years. Mean body mass index (BMI was 53.7 ± 1.27 kg/m 2 . Abnormal LFT (alanine aminotransaminase (ALT, aspartate aminotransaminase (AST alkaline phosphatase (ALK, and Gamma glutamyl transpeptidase (GTT were observed in 17.3%, with 1.5 to 2 times the upper limit of normal. ALT was most elevated in 12.2%. Abdominal ultrasonography was done in 67 (68.4% patients, of whom 51 (76% had fatty liver. Comorbid conditions including diabetes mellitus, hypertension, hyperlipidemia, bronchial asthma, and obstructive sleep apnea were observed in 51 (51.50% patients, eight of them (16.3% had abnormal LFT. No intraoperative changes of cirrhosis were observed. Conclusion: The prevalence of abnormal LFT is low in morbidly obese patients from the eastern region of Saudi Arabia. A prospective study with a larger sample and liver biopsy, is needed to clarify the findings.

    The physical school environment has been shown to be important in helping children fulfill their academic potential and in providing appropriate working conditions for staff. However, few tools have been developed that enable multi stakeholder consultation which takes into account the opinions of young students. In Saudi Arabia there has been widespread investment in schools, but few guidelines have been provided to assist design or continuous evaluation. A Post Occupancy Evaluation (POE) method was developed and used to evaluate three international primary schools in Saudi Arabia. The methods identified weaknesses in the three schools and differences in responses from the three groups consulted (children, teachers and parents). Conclusions drawn from the study are that greater efforts need to be made to draw together research about how school facilities can support teaching and learning, increase effectiveness and levels of satisfaction. POE, when used in conjunction with checklists could be used as a means of driving up standards of educational facilities.

    Full Text Available Background: Pigmentary demarcation lines (PDL are physiological abrupt transition lines between hyperpigmented skin and lighter areas. Recent evidence suggests that they involve the face. Aims: To survey facial PDL in Saudi females referred to general dermatology clinics for various complaints and determine any associated risks. Methods: Screening for facial lines was done in general dermatology clinics over a year. Whenever a patient was found to have facial PDL, a detailed questionnaire and examination were undertaken. Results: Out of 1033 patients screened, 144 patients (14% were found to have at least one of the facial PDLs. The median age of onset was 16 years. The most common line was F with 76 patients (53%. Family history was positive in 51 patients (35%. Conclusion: Facial PDL is a common and chronic pigmentary problem in Saudi women. It should be recognized and differentiated from other similar diseases like melasma. A significant proportion of patients have a milder presentation.

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

    2014-05-01

    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.

    2016-12-01

    Although the Red Sea presents a unique environment with high temperature and salinity, it remains an area that is understudied. This lack of information is reflected in many areas, one which is biodiversity. Despite increasing work on biodiversity throughout the Red Sea and an increase in Cephalopoda studies, Cephalopoda in the Red Sea remain underrepresented, which is especially pronounced in molecular analyses. Members of the class Cephalopoda are considered to be major contributors to coral reef ecosystems, serving as part of the food chain and exhibiting population increases due to targeted teleost fisheries and global climate change. In order to assess the biodiversity of Cephalopoda in the Saudi Arabian Red Sea, 87 specimens were collected from 25 reef locations between 17°N and 28°N latitude, as well as from the largest fish market in the Kingdom of Saudi Arabia. Taxonomic identification of specimens was determined using morphological comparisons with previously reported species in the Red Sea and the molecular barcoding region Cytochrome Oxidase I. 84 Red Sea sequences were compared with sequences from GenBank and analyzed using a complement of Neighbor-Joining, Maximum-Likelihood, and Bayesian inference trees. Species complexes were also investigated for Sepia pharaonis and Sepioteuthis lessoniana, which had been previously reported. From 17 cuttlefish, our study yielded three species, two of which matched previously reported species in GenBank. In addition, two distinct clades of Sepia pharaonis were identified. Of 35 squid collected, four species were identified, one of which did not match any other accepted species in literature, while Sepioteuthis lessoniana in the Red Sea formed a distinct clade. From 30 different specimens a total of five genera of Octopoda were present, forming six distinct species. Five Octopoda species collected did not match previously reported species, although many specimens were paralarvae or juveniles, so morphologically we

    The Kingdom of Saudi Arabia contains a vast desert area and the home of some of the largest deserts worldwide. This nature subjects the area to numerous dust storms. This is in addition to local emissions transported from industrial activities. The Arabian Peninsula dust storms have a major impact on air quality and affects dust cycle around the world. The nature of dust also affects air, ground traffics, and human health. Aerosols play a pivotal role in global climate change through their effects on the hydrological cycle and solar energy budget. Recently there have been some trials to study the nature of dust over the kingdom using satellite remote sensing and modeling to investigate the impact of aerosols of natural and anthropogenic origins from both local emissions and long-range transport on the air quality and atmospheric composition, yet a lot more needs to be done. In this study, data obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) on board of Terra and Aqua satellites are used to analyze aerosols properties over the thirteen provinces of the Kingdom of Saudi Arabia from April 2003 to January 2012. This analysis will help to characterize aerosol and cloud properties, and the seasonal hydrological factors to establish the relative contributions of aerosols derived from different regions to the different Saudi provinces and their impacts on local atmospheric composition and air quality. During this period, we have examined possible nature and anthropogenic/natural aerosols/dust sources. The analysis is based on important parameters including the aerosol optical depth (AOD), fine mode fraction (FMF), cloud properties including cloud top temperature (CTT), cloud top pressure (CTP) and the water vapor column. Correlation between water vapor and AOD was observed over three provinces which could be a result of pollution aerosols rather than dust and is, hence, acting as cloud condensation nuclei (CCN).

    2014-05-01

    Sedimentological, mineralogical, morphological and geochemical studies of sand dunes from ten locations in Saudi Arabia were conducted in order to determine the differences between them and to find out the provenance and tectonic setting of these sand dunes. Sixty seven samples were collected from different sand dunes types ranging in morphology from linear, barchans, parabolic to stars dunes. In overall, the sand dunes are fine to coarse grained mean grain size, moderately sorted, near symmetrical skewness with mesokurtic distribution characterized sand dunes in most locations. The sand dunes grains are subrounded in all locations except in the Red sea, Qassim, central Arabia and the eastern province which showed sub-angular grains. The main mineral compositions of studied aeolian sand dunes are quartz, feldspar, calcite, and mica. Quartz is the dominant mineral in locations with significant amount of feldspars and mica in Najran, Red sea and Central Arabia locations. Moreover, calcite is present in Sakaka and NW Empty Quarter (Jafurah). Basement related sand dunes in Najran, Central Arabia and Red sea locations are sub-mature in terms of their mineralogical maturity. Whereas, sand dunes in other locations are texturally mature except those from the Red sea which showed sub-mature sand. The sands are classified as quartz arenite, except in the basement related sand dunes in Najran, central Arabia and the Red sea are ranging from sub-arkose, sub-litharenite and lithraenite. Morphologically, parallel to sub-parallel sand ridges with NE-SW orientation occurred in east and north parts of Empty Quarter (Najran and Jafurah) and NW-SE orientation in Dahna and Nafud deserts in central and north regions of Saudi Arabia. Parabolic sand dunes characterized the Nafud desert (Hail, Sakaka, Tayma locations). Barchans and star sand dunes characterize the Empty Quarter (Jafurah). Major, trace, and rare earth elements studies were carried out to determine the composition

    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.

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

    Saudi Arabia's dependence on oil and gas to generate electricity and to desalinate sea water is widely perceived to be economically and politically unsustainable. A recent business as usual simulation concluded that the Kingdom would become an oil importer by 2038. There is an opportunity for the country to over come this problem by using its geothermal energy resources. The heat flow and heat generation values of the granites spread over a cumulative area of 161,467 sq. km and the regional stress regime over the western Saudi Arabian shield strongly suggest that this entire area is potential source of energy to support 1) electricity generation, 2) fresh water generation through desalination and 3) extensive agricultural activity for the next two decades. The country can adopt a policy to harness this vast untapped enhanced geothermal systems (EGS) to mitigate climate and fresh water related issues and increase the quantity of oil for export. The country has inherent expertise to develop this resource.

    Full Text Available In this study, the backpropagation neural network (BPNN is tested for the ability to forecast the daily volatility of two stock market indices from the Middle East and North Africa (MENA region using volume; namely Morocco and Saudi Arabia. Volatility series were estimated using the Exponential Auto-Regressive Conditional Heteroskedasticity (EGARCH model. The simulation results show that trading volume helps improving the forecasting accuracy of BPNN in Morocco but not in Saudi Arabia. As a result, volume represents valuable information flow to be used in the modeling and prediction of volatility in Morocco. In addition, it is found that BPNN overpredicts volatility during high volatile periods. This finding is important in financial applications such as asset allocation and derivatives pricing.

    The majority of human pathogens are zoonotic and rodents play an important role as reservoirs of many of these infectious agents. In the case of vector-borne pathogens, rodent reservoirs not only act as a source of infection for vectors but also serve as hosts for the vectors themselves, supporting their populations. Current data on rodent-ectoparasite relationships is limited in Saudi Arabia, however, this is needed to assess disease risk and the relative importance of different hosts for the maintenance of vector-borne pathogen cycles. In order to provide baseline data for the region that could be used to assess zoonotic disease risk, we collected and identified 771 ectoparasite specimens (ticks, fleas and mites) from 161 rodents at two wildlife research centres in Saudi Arabia and discuss our results in the context of possible zoonotic disease risk based on the hosts and vectors present.

    Full Text Available A preliminary study was conducted to know the age, sex distribution and clinical pattern of cutaneous leishmaniasis (CL in a remote hilly area, Faifa, Gizan situated in the South West region of the Kingdom of Saudi Arabia. C L accounted for nearly 5% of the new outpatient attendance in the study period (1988-90 of 20 months. Out of the 140 new patients who formed the study group, 82 were males (58.57% and 58 females (41.43% in the age range of 9 months to 60 years. Ninety two patients were children (65.71% below 15 years. including 58 boys and 34 girls and CL is a major public health problem in children of this area. The fact that out of 140 affected individuals, 134 were local Saudis and 6 non-Saudis reveals the autochthonous nature of the disease in this region. The clinical spectrum included dry crusted ulcers, erythematous indurated plaques, nodules, papules, and oozing shallow ulcers. The lesions were distributed mostly on face and extremities. Response to pentostam (Sodium stibogluconate was highly satisfactory.

    Human metapneumovirus (HMPV) is an important cause of respiratory tract illness in children. Two HMPV subgroups, A and B, and four genotypes, A1, A2, B1 and B2, have been identified. Concurrent circulation of the different genotypes in yearly epidemics has been recorded globally, but not in Saudi Arabia. The current report was designed to study HMPV epidemiology in Saudi children and to analyze the genetic diversity and circulation patterns. Nasopharyngeal aspirates (n = 174) were collected from hospitalized children in Riyadh (2008-2009). The screening of samples using real-time RT-PCR identified 19 HMPV strains. The majority of the strains belonged to subgroup B, while all strains of subgroup A were members of genotype A2. In 2008, only subgroup B was recognized, whereas in 2009 both subgroups were identified to be cocirculating at similar rates. The full-length attachment (G) gene and a partial sequence of the fusion (F) gene of positive samples were sequenced. The G gene showed a high degree of genetic diversity and exhibited a variable number of positively selected sites in different lineages. In contrast, the F gene demonstrated an extensive genetic stability with a higher tendency toward purifying selection. This is the first report on HMPV genotype circulation in Saudi Arabia; however, the exact circulation kinetics requires further retrospective and prospective study.

    Human papillomavirus (HPV) infection is a significant etiological factor and an important prognosticator in cervical cancer. Indeed, researchers worldwide have confirmed these roles for high-risk HVPs in over 70% of cervical cancer cases. According to the World Health Organization, approximately 561,200 new cancer cases (5.2% of all new cancers) are attributed to HPV infection. Over 120 types of HPV are classified further as either low-risk HPV (LR-HPV) or high-risk HPV (HR-HPV) based on their oncological potential of transforming cells. The LR-HPV types cause benign hyperproliferative lesions (i.e. genital warts) while the HR-HPV types are strongly associated with premalignant and malignant cervical lesions. Data on the prevalence of HPV, survival of infected patients, and mortality rate are scarce in Saudi Arabia. The unsubstantiated assumption of a low prevalence of HPV in Saudi Arabia has contributed to limiting HPV research in this conservative country. Therefore, the goal of this review is to shed light on the current HPV research being conducted and the prevalence of HPV in Saudi Arabia.

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

    Full Text Available This paper investigates the long-term and causal relationship between energy intensity, real GDP per capita, urbanization and industrialization in Saudi Arabia over the period 1971–2012 using the breakpoint unit root tests developed by Perron (1989 and the autoregressive distributed lag (ARDL model bounds testing to cointegration proposed by Pesaran et al. (2001 and employing a modified version of the Granger causality test proposed by Toda and Yamamoto (1995. Additionally, to test the robustness of the results, the fully modified ordinary least squares (OLS regression, the dynamic OLS regression, and the Hansen test are used. Our results show that the variables are cointegrated when energy intensity is the dependent variable. It is also found that urbanization positively affects energy intensity in both the short term and the long term. Causality tests indicate that urbanization causes economic output that causes energy intensity in the long term. Our results do not support the urban compaction hypothesis where urban cities benefit from basic public services and economies of scale for public infrastructure. Therefore, measures that slow down the rapid urbanization process should be taken to reduce energy intensity in Saudi Arabia. In addition, reducing energy inefficiency in energy consumption should be a strategy to attain sustainable development in the near future in Saudi Arabia.

    This study aimed to assess the level of knowledge, attitudes, and practices (KAP) concerning malaria and malaria prevention among rural populations residing in the southwestern region of Saudi Arabia. This was a household-based cross-sectional survey, using structured questionnaire that was developed and distributed among households selected randomly from 19 villages (clusters) located in a southwestern region of Saudi Arabia, north of the border with Yemen. The data collected were analyzed using SPSS version 20. A majority of respondents (98.4%) reported that they had heard about malaria, but only 21.7% reported that they had sufficient information about the disease. Surprisingly, the most popular source of information was the internet and social media (proportion responding positively in parenthesis) (25.5%), followed by family (21.7%), while information from health facilities contributed only 12.4%. A majority of respondents were aware that malaria is a communicable (89.1%) and deadly (70%) disease; however, only 30.2% of the respondents responded that malaria is a treatable disease. Almost all of the aware respondents (97.5%) were inclined to seek treatment from health facilities, and 63.2% preferred to seek treatment within 24h of presenting with symptoms. Regarding personal precautions, the most common practice adopted by respondents was indoor residual spraying IRS (47.3%), followed by anti-mosquito spraying (29.8%), mosquito bed nets (13.2%) and combined anti-mosquito sprays and nets on windows (4.7%). This KAP study did not show any statistically significant differences in KAP due to age; however the practices of preventive measures against malaria differed significantly by nationality (Saudi versus non-Saudi). We conclude that most populations living in the villages have an acceptable level of knowledge and awareness about malaria and seek timely treatment. However, the positive attitudes and practices in relation to personal protection and prevention

    Full Text Available Limited data exit on the epidemiology of cardiovascular risk factors in Saudi Arabia particularly in relation to the differences between local citizens and expatriates. The aim of this analysis is to describe the current prevalence of cardiovascular risk factors among patients attending general practice clinics in Saudi Arabia. In a cross- sectional epidemiological study, the presence of cardiovascular risk factors (hypertension, diabetes, dyslipidaemia, obesity, smoking, and abdominal obesity was evaluated in stable adult outpatients attending primary care clinics in Saudi Arabia. Groups comparison were made between local Saudi patients and expatriates. A total of 550 participant were enrolled form different clinics in Saudi Arabia (71% were male, mean age was 43 ± 10 years. Nearly half of the study cohort had more than two cardiovascular risk factors (49.6%. Dyslipidemia had the highest prevalence (68.4%. Furthermore, prevalence of hypertension (47.5% vs. 31.4%, dyslipidaemia (75.2% vs. 55.1% and abdominal obesity (63.9% vs. 52.2% were higher among expatriates compare to Saudis (p-value < 0.001. This analysis clearly shows that there is a high prevalence of cardiovascular risk factors prevalence in Saudi population. In addition, a significant proportion of patients with risk factors have poor overall control. Programmed community based screening is needed for all cardiovascular risk factors in Saudi Arabia. Increased awareness and improved primary care services may decrease incidence of coronary artery disease and improve overall quality of life.

    Full Text Available Background. Cardiovascular disease (CVD is one of the leading causes of death in Saudi Arabia. Saudi women in particular are more susceptible as there are sociocultural restrictions on female physical activities that may lead to high prevalence of CVD risks, especially obesity, and physical inactivity. This study aims to systematically review the published articles related to the prevalence of CVD risk among women in Saudi Arabia. The search strategy covers all published articles that assess the risk factor of CVD in Saudi Arabia from January 2000 to December 2015, using the following sources: Medline, Embase, and PsycINFO. A total of 61 studies were included. Results. Prevalence among Saudi women of smoking ranged from 1.1% to 9.1%, hypertension was 21.8%, diabetes ranged from 9.6% to 27.6%, overweight was 27%, and obesity was 40.23%, and physical inactivity ranged from 53.2% to 98.1%. Hypercholesterolemia prevalence on Saudi women on average was 24.5%, while metabolic syndrome ranged from 13.6% to 40.3%. Conclusion. The prevalence of CVD risk factors is high among women in Saudi Arabia especially in obesity and physical inactivity. Public health authorities must implement solutions from a gender specific aspect to reverse the trend and decrease the prevalence of CVDs among Saudi women.

    Background. Cardiovascular disease (CVD) is one of the leading causes of death in Saudi Arabia. Saudi women in particular are more susceptible as there are sociocultural restrictions on female physical activities that may lead to high prevalence of CVD risks, especially obesity, and physical inactivity. This study aims to systematically review the published articles related to the prevalence of CVD risk among women in Saudi Arabia. The search strategy covers all published articles that assess the risk factor of CVD in Saudi Arabia from January 2000 to December 2015, using the following sources: Medline, Embase, and PsycINFO. A total of 61 studies were included. Results. Prevalence among Saudi women of smoking ranged from 1.1% to 9.1%, hypertension was 21.8%, diabetes ranged from 9.6% to 27.6%, overweight was 27%, and obesity was 40.23%, and physical inactivity ranged from 53.2% to 98.1%. Hypercholesterolemia prevalence on Saudi women on average was 24.5%, while metabolic syndrome ranged from 13.6% to 40.3%. Conclusion. The prevalence of CVD risk factors is high among women in Saudi Arabia especially in obesity and physical inactivity. Public health authorities must implement solutions from a gender specific aspect to reverse the trend and decrease the prevalence of CVDs among Saudi women.

    Full Text Available Moringa peregrina and M. oleifera are the only Moringa species found in Saudi Arabia. Both species are drought resistant and have very high nutritional and medicinal properties. Detection of genetic diversity is of great value for the improvement of nutritional and medicinal value of these plants. The aim of the present study was to characterize a new biotype Moringa observed in Al Bahah Region, Saudi Arabia. We used 11 RAPD and 15 ISSR primers to characterize and compare the new biotype with M. peregrina and M. oleifera. Level of polymorphism generated by each marker was calculated. We also calculate Nei and Li’s coefficient to measure the genetic distance between the studied species. Level of polymorphism generated by RAPD and ISSR was 46% and 57%, respectively. RAPD and ISSR primers revealed that the new biotype shared 55 amplicons (45.08% with both M. peregrina and M. oleifera, 28 amplicons with M. peregrina (22.95%, 21 amplicons (17.21% with M. oleifera, and displayed 18 unshared amplicons (14.75%. Based on RAPD data, genetic distance between M. oleifera and M. peregrina was 0.32, whereas genetic distance between the new biotype and M. oleifera and M. peregrina was 0.21 and 0.29, respectively. For ISSR data, genetic distance between M. oleifera and M. peregrina was 0.5, whereas genetic distance between the new biotype and M. oleifera and M. peregrina was 0.36 and 0.34, respectively. Based on these results we suggested that the new biotype is a hybrid crossbred between M. peregrina and M. oleifera.

    Full Text Available Abstract Background During the last few decades, the Kingdom of Saudi Arabia (KSA experienced rapid socio-cultural changes caused by the accelerating economy in the Arabian Gulf region. That was associated with major changes in the food choices and eating habits which, progressively, became more and more "Westernized". Such "a nutritional transition" has been claimed for the rising rates of overweight and obesity which were recently observed among Saudi population. Therefore, the objectives of the current work were to 1 determine the prevalence of overweight and obesity in a sample of male college students in KSA and 2 determine the relationship between the students' body weight status and composition and their eating habits. Methods A total of 357 male students aged 18-24 years were randomly chosen from College of Health Sciences at Rass, Qassim University, KSA for the present study. A Self-reported questionnaire about the students' eating habits was conducted, and their body mass index (BMI, body fat percent (BF%, and visceral fat level (VFL were measured. Data were analyzed using SPSS statistical software, and the Chi-square test was conducted for variables. Results The current data indicated that 21.8% of the students were overweight and 15.7% were obese. The total body fat exceeded its normal limits in 55.2% of the participants and VFL was high in 21.8% of them. The most common eating habits encountered were eating with family, having two meals per day including breakfast, together with frequent snacks and fried food consumption. Vegetables and fruits, except dates, were not frequently consumed by most students. Statistically, significant direct correlations were found among BMI, BF% and VFL (P Conclusions Our findings suggest the need for strategies and coordinated efforts at all levels to reduce the tendency of overweight, obesity and elevated body fat, and to promote healthy eating habits in our youth.

Results: The survey enrolled 5,000 participants, 79%male (39.6% from Jeddah; 20% from Riyadh; and 20% from Jazan, aged between 15 and 45 years. Of the total, 1288 (25.8% had not heard about HIV/AIDS. Knowledge of HIV transmission was poor in 90% of the respondents. Of the total, 737 had read about HIV/AIDS materials and 649 participants had been previously tested for HIV. The majority of participants (85% held a negative attitude toward people living with HIV/AIDS. Those who were knowledgeable about HIV/AIDS expressed more a positive attitude. One-fifth (968, majority were men; single 55%, married 45% had engaged in non-marital sexual activity. The largest proportion of the individuals who had engaged in non-marital sex were single (54.9% followed by the married ones (40.4%. Men cited pleasure as the main reason for such activity (84.6%, whereas women (73.4% cited financial gain. Of the respondents, 53.9 and 32.1% believed that TV and schools were the best media through which information with regard to HIV/AIDS could be imparted. Conclusions: Knowledge of HIV/AIDS, its mode of transmission, and prevention measures was poor. Educational programs specifically targeted toward this group were required.

    In this study, spatial and temporal distributions of tropospheric NO2 vertical column densities over Pakistan and Saudi Arabia during the time period of 2004-2015 are discussed. Data products from the satellite instrument OMI are used. The results show a large NO2 growth over major cities of both countries, particularly the areas with rapid urbanization. Different seasonal cycles were observed over both countries. Especially, seasonal variation in tropospheric NO2 over Pakistan is largely impacted by the photolysis rate, OH radical and monsoon rains in addition to soil emissions, agriculture fires and other anthropogenic activities. While in the case of Saudi Arabia, the seasonal variation in tropospheric NO2 is completely driven by thermal power generation. Furthermore, different regions of Pakistan exhibited different seasonal trends. In the provinces of Punjab (north-east), Khyber Paktunkhwa (north-west) and Sindh (south-east), NO2 columns are maximum in winter and minimum in summer months while a reversed seasonality was observed in the province of Baluchistan (south-west). We compared the observed Spatio-temporal patterns to existing emission inventories and found that for the most populated provinces the NOx emissions are clearly dominated by anthropogenic sources. In these areas also the strongest positive trends were observed. NOx released from soils and produced by lightning both together contribute about 20% for the provinces of Punjab, Sindh, and Khyber Pakhtunkhwa, while its contribution in Baluchistan is much stronger (~50%). NOx emissions from biomass burning are negligible. This finding can also explain the observed summer maximum in Baluchistan since the highest lightning activity occurs during the Monsoon season. Our comparison also indicates that the inventories of anthropogenic NOx emissions over Pakistan seem to underestimate the true emissions by about a factor of two.

  5. Water management during climate change using aquifer storage and recovery of stormwater in a dunefield in western Saudi Arabia

    An average of less than 50 mm yr-1 of rainfall occurs in the hyperarid region of central Western Saudi Arabia. Climate change is projected to create greater variation in rainfall accumulation with more intense rainfall and flood events and longer duration droughts. To manage climate change and variability in ephemeral stream basins, dams are being constructed across wadi channels to capture stormwater, but a large percentage of this stored water is lost to evaporation. A dam/reservoir system located in Wadi Al Murwani in Western Saudi Arabia was recently constructed and is expected to contain a maximum stored water volume of 150 million m3. A hydrologic assessment of a dunefield lying 45 km downstream was conducted to evaluate its potential use for aquifer storage and recovery of the reservoir water. A 110 m elevation difference between the base of the dam and the upper level of the dunefield occurs, allowing conveyance of the water from the reservoir to the dunefield storage site by gravity feed without pumping, making the recharge system extremely energy efficient. Aquifer storage and recovery coupled with dams would allow water management during extreme droughts and climate change and has widespread potential application in arid regions. 2014 IOP Publishing Ltd.

    This study was conducted to assess the relationship between occurrence of gastric cancer and peptic ulcer, and the presence of H. pylori cagA gene and anti-CagA IgG, and to estimate the value of these antibodies in detecting infection by cagA gene-positive H. pylori strains in Saudi patients. The study included 180 patients who were subjected to upper gastrointestinal endoscopy in Taif province and Western region of Saudi Arabia (60 gastric cancer, 60 peptic ulcer, and 60 with non-ulcer dyspepsia). Gastric biopsy specimens were obtained and tested for H. pylori infection by rapid urease test and culture. PCR was performed on the isolated strains and biopsy specimens for detection of the cagA gene. Blood samples were collected and tested for CagA IgG by ELISA. H. pylori infection was detected among 72.8% of patients. The cagA gene and anti-CagA IgG were found in 63.4% and 61.8% of H. pylori-infected patients, respectively. They were significantly (p ulcer compared with those with non-ulcer dyspepsia. Detection of the CagA IgG was 91.6% sensitive, 89.6% specific, and 90.8% accurate compared with detection of the cagA gene. Its positive and negative predictive values were 93.8% and 86%, respectively. The study showed a significant association between the presence of the cagA gene and gastric cancer and peptic ulcer disease, and between anti-CagA IgG and the cagA gene in Saudi patients. However, a further larger study is required to confirm this finding.

    2010-01-01

    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.

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

    Full Text Available Tetramorium amalae sp. n. is described and illustrated from Saudi Arabia based on two worker caste specimens collected in Al Bahah region. The new species belongs to the T. shilohense group and appears to be closely related to T. dysderke Bolton from Nigeria. T. amalae is distinguished by having well-developed frontal carinae, smaller eyes, greater head length and width, greater pronotal width, and the petiole node is longer than broad. Tetramorium latinode Collingwood & Agosti is recorded for the first time from Saudi Arabia and for only the second time since the original description. The worker caste of T. latinode is redescribed and illustrated using scanning electron micrographs to facilitate recognition and the gyne is described for the first time with observations given on species relationships, biology and habitat. A revised key to the nineteen Tetramorium species recorded from Arabian Peninsula based on worker castes is provided. Tetramorium bicarinatum (Nylander is recorded for the first time from Saudi Arabia. It is suggested that T. amalae and T. latinode are endemic to the Arabian Peninsula.

    Full Text Available Recent genome-wide association studies identified single nucleotide polymorphisms (SNPs on the chromosome 9p21.3 conferring the risk for CAD (coronary artery disease in individuals of Caucasian ancestry. We performed a genetic association study to investigate the effect of 12 candidate SNPs within 9p21.3 locus on the risk of CAD in the Saudi population of the Eastern Province of Saudi Arabia. A total of 250 Saudi CAD patients who had experienced an myocardial infarction (MI and 252 Saudi age-matched healthy controls were genotyped using TaqMan assay. Controls with evidenced lack of CAD provided 90% of statistical power at the type I error rate of 0.05. Five percent of the results were rechecked for quality control using Sanger sequencing, the results of which concurred with the TaqMan genotyping results. Association analysis of 12 SNPs indicated a significant difference in the genotype distribution for four SNPs between cases and controls (rs564398 p = 0.0315, χ2 = 4.6, odds ratio (OD = 1.5; rs4977574 p = 0.0336, χ2 = 4.5, OD = 1.4; rs2891168 p = 1.85 × 10 − 10, χ2 = 40.6, OD = 2.1 and rs1333042 p = 5.14 × 10 − 9, χ2 = 34.1, OD = 2.2. The study identified three protective haplotypes (TAAG p = 1.00 × 10 − 4; AGTA p = 0.022 and GGGCC p = 0.0175 and a risk haplotype (TGGA p = 2.86 × 10 − 10 for the development of CAD. This study is in line with others that indicated that the SNPs located in the intronic region of the CDKN2B-AS1 gene are associated with CAD.

    Foot-and-mouth disease viruses are often restricted to specific geographical regions and spread to new areas may lead to significant epidemics. Phylogenetic analysis of sequences of the VP1 genome region of recent outbreak viruses from Libya and Saudi Arabia has revealed a lineage, O-Ind-2001, normally found in the Indian subcontinent. This paper describes the characterization of field viruses collected from these cases and provides information about a new real-time RT-PCR assay that can be used to detect viruses from this lineage and discriminate them from other endemic FMD viruses that are co-circulating in North Africa and western Eurasia.

    Saudi Arabia, divided into 5 planning regions, 13 administrative regions and further to 118 governorates (administrative units), has diverse demographic characteristics from one region to another and from one governorate to another. Rural to urban migration and an exodus of immigrants characterize the Kingdom, where development planning depend largely upon local level requirements based on economic activities. An attempt was made to analyze the population characteristics, such as population size, sex ratio, native to foreigner ratio, and households and persons per households by keeping governorate as unit of analysis. Data of two census period (2004 and 2010) was used in order to explore the situation and track the intercensal changes. Large variations in population were observed between governorates and it varied from 3686 to 5,007,886 in 2010. Governorates are divided according to the number of native population demarcating urbanization, modernization and infrastructure. During the intercensal period, the number of small governorates reduced and medium and large sized governorates increased mainly due to population growth. The average population in governorates was increased in total and in the larger governorates during the period. However, we noticed a reduction in the average population size in the small and medium sized governorates. The size of native population in a governorate influences the sex ratio, the native-foreigner ratio and the persons per household as well as the variations within the group of governorates. Analyses of lower level data shall aid not only to understand the situation but also to support local development policies.

    2016-02-01

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

    The health promotion practice of nurses working in Saudi Arabia is unidentified. The purpose of this study was to investigate the perceived health promotion practice of staff nurses in Saudi Arabia. This was achieved by surveying the views of nurses (n = 614), doctors (n = 130) and patients (n = 322) in 10 hospitals located in the Eastern Province of the country using a self-report questionnaire. There was agreement that nurses had the necessary skills to promote health in general and had sufficient knowledge to promote health in the three specific areas explored: physical activity, smoking cessation and weight control. However, the findings also showed that the majority of participants wanted nurses to give priority to acute care over health promotion within the hospital setting and that patients dislike nurses asking about health-related behaviours when these are not directly relevant to their presenting health problems. Concerns were also raised about the language and cultural competency of a largely migrant nursing workforce to effectively communicate health promotion messages to patients. In view of the findings, policy-makers in Saudi Arabia need to consider providing appropriate training programmes for nurses to introduce the wider concept of their health promotion role. Health promotion protocols, strategies and standards to support nurses to more effectively implement health promotion with their routine practice are also required. It is suggested that, while reliance on a largely migrant workforce who do not speak Arabic continues, the potential benefits of a good quality interpretation service to improve nurse-patient communication should be considered.

    Full Text Available The Kingdom of Saudi Arabia (KSA has witnessed a huge increase in construction during the last two decades. However, many projects experienced time delays, cost overruns and the generation of massive amounts of waste. To address these challenges, lean construction has been introduced into the Saudi construction industry; however, it is still in its infancy. This study therefore investigates the current state of lean construction implementation in the construction industry in the KSA. The objectives are to identify: the types of construction waste, level of use of tools that support the implementation of lean construction, stages of application of lean methods, and the benefits of lean construction. To achieve these objectives, a structured questionnaire survey of 282 construction professionals was carried out. After the analysis of the collected data using mean score and Anova test, the following conclusions were made.  In the construction industry in the KSA, waiting is the most common type of waste, while Computer Aided Design (CAD is the conventional tool supporting the implementation of lean construction. Furthermore, the data suggests that lean construction is most commonly used in the construction stage of projects while customer satisfaction is the main benefit derived from lean construction practices. This study concludes that the level of implementation of lean construction in the KSA construction industry is increasing. The results will help benchmark the current state of lean construction implementation, which will enable the construction industry to identify strategies to implement lean construction in Saudi Arabia in accordance with their needs and project goals, to achieve better productivity.

    INTRODUCTION: Although acne vulgaris is common in adolescents, information on their understanding of acne is minimal. OBJECTIVES: To evaluate the perceptions and beliefs of Saudi youth on acne. MATERIALS AND METHODS: Three hundred twenty-nine male students (aged 13–22 years) from 6 secondary schools in the Eastern Saudi Arabia completed a self-reported questionnaire on knowledge, causation, exacerbating and relieving factors of acne. Data were analyzed by SPSS version 15.0. Results of subjects with acne, a family history of acne, and parents' educational levels were compared. Differences between the analyzed groups were assessed by a Chi-square test; p ≤ 0.05 was considered statistically significant. RESULTS: Over half (58.9%) of the participants considered acne a transient condition not requiring therapy. Only 13.1% knew that the proper treatment of acne could take a long time, even several years. Over half (52%) thought acne can be treated from the first or after few visits to the doctor. Popular sources of information were television/radio (47.7%), friends (45.6%), and the internet (38%). Only 23.4% indicated school as a source of knowledge. Reported causal factors included scratching (88.5%) and squeezing (82.1%) of pimples, poor hygiene (83.9%), poor dietary habits (71.5%), and stress (54.1%). Ameliorating factors included frequent washing of the face (52.9%), exercise (41.1%), sunbathing (24.1%), and drinking of mineral water (21%). The correlations of these facts are discussed. CONCLUSION: Results of this study point out that misconceptions of acne are widespread among Saudi youth. A health education program is needed to improve the understanding of the condition.

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

    2016-01-01

    Background: The prevalence of Type-2 Diabetes is dramatically increasing in urban areas within Saudi Arabia. Hence, Type-2 Diabetes has now become the most common public health problem. Understanding the major risk factors for and barriers to control Type-2 Diabetes may lead to strategies to prevent, control, and reduce in the burden of disease cases. Objective: To describe risk factors for and barriers to control Type- 2 Diabetes in Saudi Arabia. Methods: The literature search was conducted on risk factors for and barriers to control Type- 2 Diabetes in Saudi Arabia using the databases PubMed, MEDLINE, and Google Scholar (2007-2015). The literature search yielded 80 articles, of which 70 articles were included in this review after excluding non-relevant articles. Results: The literature review revealed that obesity, physical inactivity, unhealthy diet, smoking, and aging are the major risk factors for Type-2 Diabetes in Saudi Arabia. Further, the review allocated a complex set of barriers including, lack of education, social support, and healthy environment. These barriers may hinder Saudis with Type-2 Diabetes from controlling their disease. Conclusion: The prevalence of Type-2 Diabetes is high among the Saudi population and represents a major public health problem. Effective research programs are needed to address the modifiable risk factors for and barriers to control Type-2 Diabetes among Saudi population. PMID:27157156

    Full Text Available Remote projects have their unique problems that are caused mainly by the remoteness of the project itself thus the loose control over management. This is due to a number of reasons such as lack of human resources and infrastructure. Research studies that were undertaken worldwide - regarding this issue- has highlighted few unique management problems. The aim of this paper is to investigate how far the IT tools would help in managing remote construction projects in the Kingdom of Saudi Arabia (KSA. Due to the lack of previous research regarding remote projects within the Gulf region and the KSA, a pilot study was conducted in 2009 to define and test the wording of questions that are part of the main survey. The main survey was undertaken on Saudi Electric Company (SEC. The study found that IT systems and tools have the potential but this potential is hindered by a number of technical, managerial, staff factors. Therefore, successful application of IT systems would require changes to the present management settings at various levels. This would ensure that the SEC is capable of achieving the full benefit from using these advanced systems.

Subjects: The subjects included in this study were 58 patients with asthma, 47 patients with rhinitis and 112 patients with urticaria. They all gave clinical history suspecting food as causing or aggravating their symptoms. Methods: Specific IgE antibodies to different food allergens were measured in the patients serum by using the Pharmacia CAP Radioaller gosorbent (RAST Fluoroimmunoassay (FEIA test. Results: IgE-antibodies specific for different foods were detected in 38 (17.5% out of 217 patients. Most positive reactions were detected in urticaria patients (9.7% followed by asthmatic patients (5.5% and allergic rhinitis (2.3%. Reactions to peanut (22.6%, egg white (14.5 and cow′s milk (12.9% were very prominent. Conclusion: The prevalence rate of food allergy seems to be high in Saudi patients when compared to studies from other regions. The pattern of food reactions, detected in this study, can be utilized in diagnosis of patients with suspected food allergy. Further studies will be required to obtain more information about the prevalence and incidence rates among different patient groups.

  2. A review of environmental governance and its effects on concentrate discharge from desalination plants in the Kingdom of Saudi Arabia

    2013-01-01

    The most likely environmental impact of concentrate discharges (in most instances twice the concentration of the ambient environment) leaking from desalination plants on local marine ecosystems has been controversially discussed for many years. Increasing water demand and lack of renewable natural water resources in Saudi Arabia also result in greater dependence on desalination and consequently amplify the impact on marine environment and multifactorial ecosystems in near-field areas of desalination discharges. Accurate scientific baseline data should furnish information on various factors such as intake- and outfall locality, brine (concentrate) discharge and chemical characteristics (i.e. effluent concentration, mass flow rates (flux)), local effects, and even cumulative effects of desalination activities, at least on a regional and even on a national scale. Even if such data were available, in many cases they are non-transparent and are not even accessible, or tend to be overlooked as a result of ambiguous desalination-related policies. This paper focuses on national environmental regulations in the Kingdom of Saudi Arabia (KSA) and how such regulations help control the flow of concentrate discharge into the receiving waters. © 2013 Desalination Publications.

Descriptive statistics were used to report the results.Results: The responses indicated inadequate health-related practices in the surveyed group: 22.2% brushed their teeth twice daily, 73.6% never flossed their teeth, and while 80.2% visited a physician in the past year, only 12.6% visited a dentist during the same year. Of the respondents, 94.8% reported that they had never received advice on oral hygiene tasks in relation to diabetes from a health professional. Awareness about the diabetes and periodontal disease association was limited: 46.7% knew that diabetics have gum problems more often if their blood sugar stays very high, and only 21.8% knew that gum disease makes it harder to control blood sugar in diabetic patients. A significant association (P<0.05 was found between a higher level of education and greater general and oral awareness, as well as a significant association (P<0.05 between longer duration of disease, regular exercise, and regular visits to the physician and awareness about diabetes mellitus. Additionally, a significant association (P<0.05 was found between regular dental visits and both periodontal disease and diabetes awareness. Family and friends were the main source of

    2014-01-01

    Disability is a major challenge for the Saudi healthcare sector. Data about the incidence and prevalence of impairment and disability and sociodemographic characteristics of people with disabilities are scarce and incomplete and probably underestimate the actual burden of disability. Policies and legislation have supported the equal rights of persons with disabilities, but ineffective implementation of these laws has created a gap between the intended aims and the actual provision of services. Clearly, more research is needed to plan for appropriate management programs, effective implementation of primary prevention strategies, and proper allocation of health resources in this area.

    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.

    2013-01-01

    Full Text Available The professional content of sleep medicine has grown significantly over the past few decades, warranting the recognition of sleep medicine as an independent specialty. Because the practice of sleep medicine has expanded in Saudi Arabia over the past few years, a national regulation system to license and ascertain the competence of sleep medicine physicians and technologists has become essential. Recently, the Saudi Commission for Health Specialties formed the National Committee for the Accreditation of Sleep Medicine Practice and developed national accreditation criteria. This paper presents the newly approved Saudi accreditation criteria for sleep medicine physicians and technologists.

    Despite emerging evidence about the benefits of telemedicine, there are still many barriers and challenges to its adoption. Its adoption is often cited as a failed project because 75% of them are abandoned or 'failed outright' and this percentage increases to 90% in developing countries. The literature has clarified that there is neither one-size-fit-all framework nor best-practice solution for all ICT innovations or for all countries. Barriers and challenges in adopting and implementing one ICT innovation in a given country/organisation may not be similar - not for the same ICT innovation in another country/organisation nor for another ICT innovation in the same country/organisation. To the best of our knowledge, no comprehensive scientific study has investigated these challenges and barriers in all Healthcare Facilities (HCFs) across the Kingdom of Saudi Arabia (KSA). This research, which is undertaken based on the Saudi Telemedicine Network roadmap and in collaboration with the Saudi Ministry of Health (MOH), is aimed at identifying the principle predictive challenges and barriers in the context of the KSA, and understanding the perspective of the decision makers of each HCF type, sector, and location. Three theories are used to underpin this research: the Unified Theory of Acceptance and Use of Technology (UTAUT), the Technology-Organisation-Environment (TOE) theoretical framework, and the Evaluating Telemedicine Systems Success Model (ETSSM). This study applies a three-sequential-phase approach by using three mixed methods (i.e., literature review, interviews, and questionnaires) in order to utilise the source triangulation and the data comparison analysis technique. The findings of this study show that the top three influential barriers to adopt and implement telemedicine by the HCF decision makers are: (i) the availability of adequate sustainable financial support to implement, operate, and maintain the telemedicine system, (ii) ensuring conformity of

    In this study we assessed the current status of coral reefs along the Saudi Arabian coast of the Red Sea. Among the three growth forms of Acroporid corals, the branching forms were found to dominate in the Farassan Islands (44.55%±11.10%cover) fol-lowed by tabular forms in the Doga Islands (ranging between 18%±6.47% and 18.30%±9.47% cover). Digitate forms were rarely found along the coast except at Maqna. Among the five growth forms of non-Acroporid corals, we observed maximum cover of branching forms in the Yanbu offshore area (58.89%±15.11% cover) followed by the Jeddah coast (24.76%±14.04% cover). The Millepora spp., a non-Scleractinian coral, was abundant at all the near-shore sites, such as Jeddah (10.70%±8.21%) and Al-Wajh (9.81%±6.69%). The live coral cover (including both Scleractinian and non-Scleractinian corals) of Saudi Red Sea coast was seen to be higher in the north and gradually decrease towards the south. Principal Component analysis showed that the contribution of Acro-porid corals was greater in the southern region than in the northern and middle regions, but vice-versa in the case of non-Acroporid corals. Bray-Curtis cluster analysis categorized all the study sites into two major clusters with 60% similarity. Among them, one cluster-forming sites from Maqna to Masturah (Northern region) and the second one comprised the middle and southern regions (Jeddah to Farassan Islands), and one outlier Rabigh.

    Many arid and semi-arid regions have sparse precipitation observing networks, which limits the capacity for detailed hydrological modelling, water resources management and flood forecasting efforts. The objective of this work is to evaluate the utility of relatively high-spatial resolution rainfall products to reproduce observed multi-decadal rainfall characteristics such as climatologies, anomalies and trends over Saudi Arabia. Our study compares the statistical characteristics of rainfall from 53 observatories over the reference period 1965-2005, with rainfall data from six widely used gauge-based products, including APHRODITE, GPCC, PRINCETON, UDEL, CRU and PREC/L. In addition, the performance of three global climate models (GCMs), including CCSM4, EC-EARTH and MRI-I-CGCM3, integrated as part of the Fifth Coupled Model Intercomparison Project (CMIP5), was also evaluated. Results indicate that the gauge-based products were generally skillful in reproducing rainfall characteristics in Saudi Arabia. In most cases, the gauge-based products were also able to capture the annual cycle, anomalies and climatologies of observed data, although significant inter-product variability was observed, depending on the assessment metric being used. In comparison, the GCM-based products generally exhibited poor performance, with larger biases and very weak correlations, particularly during the summertime. Importantly, all products generally failed to reproduce the observed long-term seasonal and annual trends in the region, particularly during the dry seasons (summer and autumn). Overall, this work suggests that selected gauge-based products with daily (APHRODITE and PRINCETON) and monthly (GPCC and CRU) resolutions show superior performance relative to other products, implying that they may be the most appropriate data source from which multi-decadal variations of rainfall can be investigated at the regional scale over Saudi Arabia. Discriminating these skillful products is

    Full Text Available Objective: To estimate the awareness of cardiovascular disease (CVD and their determinants in a screening campaign in the eastern province of Saudi Arabia. Materials and Methods: All national residents in the eastern province of Saudi Arabia aged 30 years and above, were invited to participate in a screening campaign for the early detection of diabetes and hypertension at more than 300 examination posts throughout the eastern province. A pre-structured questionnaire was designed to collect data on age, gender, marital status, education level, occupation, lifestyle habits, and history of heart attack, angina, arterial disease, stroke, and transient ischemic attack. Weight, height, blood pressure, and glucose concentration were measured. Results: Out of 197,681 participants, 5372 (2.7% were aware of a history of a CVD. The prevalence correlated well with age. It was higher in women, widows, and subjects with lower level of education. More than 75% of affected subjects had two or more risk factors. Conclusion: A substantial proportion of those with a history of CVD had multiple risk factors, necessitating an effective, focused policy for the prevention and treatment. Increased effort is required to promote an awareness of cardiac disease and also probably target primary care providers involved in the screening process.

    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.

    Full Text Available Context: Epidemiological studies have shown that vitiligo is a complex trait, involving combinations of pathogenic effects of multiple susceptibility genes as well as environmental risk factors. Aim: To observe whether consanguinity increased the incidence of vitiligo in Saudi patients from Arar. Patients and Methods: This study included 69 Saudi patients with vitiligo and their families. These patients, selected from the experience specialist dermatology center in Arar, from April 2011 to 2012, were interviewed by a dermatologist to confirm the diagnosis and complete a questionnaire. Results: A total of 69 patients, 40 males and 29 females were selected. Their mean age was 34.5 ± 11.8 years with the median age of 23 years. The mean age at onset of disease was 27.9 ± 12.9 years. The mean duration of the disease was 9.7 ± 5.3 years. The frequency of focal, vulgaris, universal, and acrofacial subtypes was 22 (31.9%, 21 (30.4%, 8 (11.6%, and 18 (26.1%, respectively. A positive family history of vitiligo was obtained in 45 (65.2% cases. A comparison of the frequency of vitiligo among siblings in relation to the general population was more in accord with the multifactorial model. Conclusion: Consanguinity in marriage increases the incidence of the disease. Therefore, genetic counseling and premarital examination would be important contributions to lower the prevalence of vitiligo.

    Full Text Available As internet use in Saudi Arabia are dramatically increasing, a powerful demand is being laid down on internet service purpose where this paper aims at identifying major factors that influence these demand pertaining to internet services. Within a selected theoretical model, such multiple factors are being conceptualized and interrelated. Using time series data, the Ordinary Least Square (OLS technique is employed to analyze the relationships. The results of the model indicated clearly that using the internet in Saudi Arabia is influenced most strongly by the number of educated people, the number of mobile subscribers, income, the number of fixed lines, and employment level. The results also suggest that demographic factors have a significant impact on the demand for internet, specifically, the number of educated people and levels of employment. This paper concludes with a recommendation on increasing the level of understanding of those the factors affecting practitioners who plan and promote new forms of internet services in the current competitive market.

    2012-09-01

    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.

Heavy metals contamination in cosmetic products is becoming an important health problem in both worldwide and locally at the level of the Kingdom of Saudi Arabia (KSA.The aim of this study was tostudy.Quantitatively estimated heavy metals “lead, cadmium, mercury and Arsenic” using graphite.Methods: total of 21 popular brands used lipstick products sold in Riyadh market samples from 3 different types of lipsticks frequently used among females in Saudi Arabia was digested. The digested samples were analyzed for lead, cadmium, mercury and Arsenic using graphite furnace- atomic absorption spectrometry. Results:the mercury concentration was high followed by arsenic and cadmium, finally lead. The results indicate that the toxic heavy metals in all the samples were below the US FDA and SFDA permissible limits for cosmetic products with the exception the mercury content in some lipstick samples was higher than SFDA. There was no significant difference among the lipsticks in price categories.Conclusion: Continuous use and possible unintended ingestion of these toxic heavy metals, though in low levels in the cosmetics, may pose potential health risk due to their bioaccumulation in body organs.

    Full Text Available The number of novel giant viruses identified and characterized from the recently proposed order Megavirales has increased in recent years and new questions have been raised regarding viral diversity and evolution. Here, we describe the isolation and characterization of Saudi moumouvirus (SDMV, a new giant virus belonging to Mimivirus lineage B, isolated from a sewage sample taken from the King Abdulaziz University hospital in Jeddah, Saudi Arabia. SDMV presented 500 nm icosahedral particles with a 1,046,087 bp genome, which is larger than moumouvirus-like genomes which have been described in the past. The SDMV genome was predicted to encode 868 ORFs, ranging in size from 54 to 2,914 amino acids, with a mean size of 349 aa. Furthermore, this genome was predicted to encode 40 new genes (ORFans without similarity with other sequences (ORFan L850 transcript was detected by qPCR in infected amoeba, in addition to 42 hypothetical proteins (pseudo-ORFs with less than 100 aa, which matched other sequences in the NCBI nr database. Phylogenetic analysis showed that SDMV clustered together with mimiviruses from lineage B, including moumouvirus-like strains. It is, therefore, the 3rd Mimivirus to be isolated in Asia and the first of group B.

The descriptive data were analyzed using chi-square test. The level of statistical significance was set at P<0.05. Eighty (48.5% of the responding workers had pain in neck, shoulders, lower back, hand, knee, or ankle. The majority of respondents had low back pain (50% followed by knee pain (20%. The average intensity of pain at all sites during activity and rest was 6.65 and 3.59, respectively. Thirty-four (42.5% respondents had dull aching pain and 24 (30% had cramping pain. There was an association between years of experience, duration of break during work, and use of protective equipment with the prevalence of musculoskeletal pain in construction workers (P<0.05. Most of the workers complaining of pain got medical treatment (62.5% and only 25% received physical therapy. It can be concluded from this study that the prevalence of musculoskeletal pain among construction workers in Saudi Arabia is high.

    Full Text Available Background/Aim: Although international guidelines in inflammatory bowel disease (IBD management are currently available, variations in IBD care still exist. The aim of this study was to determine the extent of the variation in IBD care among Saudi pediatric gastroenterologists.Materials and Methods: A cross-sectional survey was conducted among all pediatric gastroenterologists who were members of the Saudi Society of Pediatric Gastroenterology, Hepatology, and Nutrition (SASPGHAN from August 2015 to December 2015. The questionnaire included items on demographic characteristics and utilization of different diagnostic and therapeutic interventions in IBD care. Results: Of the 45 registered pediatric gastroenterologists surveyed, 37 (82% returned the survey from 20 centers across the country; 75.7% were practicing in tertiary care centers. There was a considerable variation in the use of different diagnostic tests during the initial evaluation of the disease. Utilization of calprotectin assays, magnetic resonance imaging enterography, and bone densitometry seemed to vary the most between physicians practicing at tertiary and secondary care centers. There were statistically significant differences in the prescription of biological therapy between the two groups. Conclusions: We found a considerable variation in the use of different diagnostic and therapeutic interventions in the management of pediatric IBD patients. Such variations could lead to unintended differences in patient outcomes. Implementation of the available evidence-based guidelines may limit such variations and ultimately could improve the quality of IBD care provided.

    Full Text Available Background: Despite strong evidence of the benefits of rapid sequence intubation in neonates, it is still infrequently utilized in neonatal intensive care units (NICU, contributing to avoidable pain and secondary procedure-related physiological disturbances. Objectives: The primary objective of this cross-sectional survey was to assess the practice of premedication and regimens commonly used before elective endotracheal intubation in NICUs in Saudi Arabia. The secondary aim was to explore neonatal physicians′ attitudes regarding this intervention in institutions across Saudi Arabia. Methods: A web-based, structured questionnaire was distributed by the Department of Pediatrics, Umm Al Qura University, Mecca, to neonatal physicians and consultants of 10 NICUs across the country by E-mail. Responses were tabulated and descriptive statistics were conducted on the variables extracted. Results: 85% responded to the survey. Although 70% believed it was essential to routinely use premedication for all elective intubations, only 41% implemented this strategy. 60% cited fear of potential side effects for avoiding premedication and 40% indicated that the procedure could be executed more rapidly without drug therapy. Treatment regimens varied widely among respondents. Conclusion: Rates of premedication use prior to non-emergent neonatal intubation are suboptimal. Flawed information and lack of unified unit policies hampered effective implementation. Evidence-based guidelines may influence country-wide adoption of this practice.

    The number of novel giant viruses identified and characterized from the recently proposed order Megavirales has increased in recent years and new questions have been raised regarding viral diversity and evolution. Here, we describe the isolation and characterization of Saudi moumouvirus (SDMV), a new giant virus belonging to Mimivirus lineage B, isolated from a sewage sample taken from the King Abdulaziz University hospital in Jeddah, Saudi Arabia. SDMV presented 500 nm icosahedral particles with a 1,046,087 bp genome, which is larger than moumouvirus-like genomes which have been described in the past. The SDMV genome was predicted to encode 868 ORFs, ranging in size from 54 to 2,914 amino acids, with a mean size of 349 aa. Furthermore, this genome was predicted to encode 40 new genes (ORFans) without similarity with other sequences (ORFan L850 transcript was detected by qPCR in infected amoeba), in addition to 42 hypothetical proteins (pseudo-ORFs) with less than 100 aa, which matched other sequences in the NCBI nr database. Phylogenetic analysis showed that SDMV clustered together with mimiviruses from lineage B, including moumouvirus-like strains. It is, therefore, the third Mimivirus to be isolated in Asia and the first of group B. PMID:28066355

    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.

    Full Text Available Energy and water are the two major need of the globe which need to be addressed for the sustenance of the human beings on this planet. All the nations, no matter most populous, developed and developing need to diversify the means and ways of producing energy and at the same time guarding the environment. This study aims at techno economical feasibility of producing energy using PV solar panels and utilizing it to pump-water at Dhahran, Riyadh, Jeddah, Guriat, and Nejran regions in Saudi Arabia. The solar radiation data from these stations was used to generate electricity using PV panels of 9.99 kW total capacity. Nejran region was found to be most economical in terms of minimal payback period and cost of energy and maximum internal rate of return whereas PV power production was concerned. Water-pumping capacity of the solar PV energy system was calculated at five locations based on the PV power production and Goulds model 45J series of pumps. Monthly total and annual total water pumping capacities were determined. Considering the capital cost of combined solar PV energy system and the pump unit a cost analysis of water pumping for a well of 50 m total dynamic head (TDH was carried out. The cost of water pumping was found to vary between 2 and 3 /m3.

  9. Biogeographic Patterns of Reef Fish Communities in the Saudi Arabian Red Sea

    2014-12-01

    As a region renowned for high biodiversity, endemism and extreme temperature and salinity levels, the Red Sea is of high ecological interest. Despite this, there is relatively little literature on basic broad scale characteristics of the biodiversity or overall reef fish communities and how they change across latitude. We conducted visual transects recording the abundance of over 200 species of fish from 45 reefs spanning over 1000 km of Saudi Arabian coastline and used hierarchical cluster analysis to find that for combined depths from 0m-10m across this geographical range, the reef fish communities are relatively similar. However we find some interesting patterns both at the community level across depth and latitude as well as in endemic community distributions. We find that the communities, much like the environmental factors, shift gradually along latitude but do not show distinct clusters within the range we surveyed (from Al-Wajh in the north to the Farasan Banks in the south). Numbers of endemic species tend to be higher in the Thuwal region and further south. This type of baseline data on reef fish distribution and possible factors that may influence their ranges in the Red Sea are critical for future scientific studies as well as effective monitoring and in the face of the persistent anthropogenic influences such as coastal development, overfishing and climate change.

    Al-Harbi, Ahmad Abdulaziz

    In recent years, load forecasting has become one of the main fields of study and research. Short Term Load Forecasting (STLF) is an important part of electrical power system operation and planning. This work investigates the applicability of different approaches; Artificial Neural Networks (ANNs) and hybrid analytical models to forecast residential load in Kingdom of Saudi Arabia (KSA). These two techniques are based on model human modes behavior formulation. These human modes represent social, religious, official occasions and environmental parameters impact. The analysis is carried out on residential areas for three regions in two countries exposed to distinct people activities and weather conditions. The collected data are for Al-Khubar and Yanbu industrial city in KSA, in addition to Seattle, USA to show the validity of the proposed models applied on residential load. For each region, two models are proposed. First model is next hour load forecasting while second model is next day load forecasting. Both models are analyzed using the two techniques. The obtained results for ANN next hour models yield very accurate results for all areas while relatively reasonable results are achieved when using hybrid analytical model. For next day load forecasting, the two approaches yield satisfactory results. Comparative studies were conducted to prove the effectiveness of the models proposed.

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

    Alsharari, Salman

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

    Measurement of indoor Concentrations were performed in Zulfi city of Saudi Arabia, using CR-39 track etch detectors. This investigation focused on the influence of different parameters, namely different locations, school categories, school building types, and room type as well as on the existence of differences in radon concentration at floor levels. We divided the Zulfi city into five regions, keeping in mind their geographical locations between Tuwaiq Mountains and Al-Thuwayrat sands. The measured average radon concentrations for regions 1-5 respectively are: 87.0±14.2 Bq/m3, 83.4±6.0 Bq/m3, 61.6±6.4 Bq/m3, 63.7±5.4 Bq/m3 and 87.5±6.Bq/m3 and the minimum concentrations are 28.0 Bq/m3, 5.5 Bq/m3, 1.1 Bq/m3, 1.0 Bq/m3 and 24 Bq/m3 respectively. These results are still within normal limits and below the action level of 148 Bqm-3 set by the U.S. Environmental Protection Agency (EPA). A test of significance using Minitab program was applied to investigate if radon levels in regions are significantly different from each other. We tried all combinations, and found the following results. The "within regions" (different location) test yielded, region 2 is not significant versus region "1" (p = 0.783) and versus region "5" (P = 0.646), whereas it is significant versus region "3" ( P = 0.0160) and also versus region "4" (p = 0.018). We investigated government and rented school's building also and none was found significantly different (p = 0.052). Floors of the same building were tested in order to examine the radon concentration as a function of storey level. No significant difference was observed at floor levels (p = 0.009). When girl's schools versus Boys and kindergartens schools were tested they were found significantly different. It is believed that this significant difference is due to geographical nature of the area, since most of the girl's schools were selected from regions 2 and 3, these regions are relatively close to the Tuwaiq mountains whereas other

    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.

    Full Text Available This study aimed to assess acquired immune deficiency syndrome (AIDS-related knowledge, attitudes, and risk perception among Saudi nursing students, and to identify predictors of their willingness to provide care for patients with AIDS. A cross-sectional study of 260 baccalaureate nursing students at King Saud bin-Abdulaziz University for Health Sciences, Riyadh, Saudi Arabia, was done using a previously validated instrument. Students’ knowledge percentage mean score (PMS on AIDS was 72.93 ± 10.67 reflecting an average level of knowledge. There were many misconceptions about how AIDS is transmitted, for example, use of same toilets and bathrooms and washing clothes together (24.9%, swimming (53.7%, and coughing and sneezing (49.6%. Nursing students reported an overall negative attitude toward AIDS, with a PMS of 43.48 ± 9.21. The majority of students agreed that AIDS patients should be isolated from other patients (83%, and should not share the room with other noninfected patients (81.8%, and some reported that people living with AIDS deserve what has happened to them (24.7%. After controlling for confounders, students’ poor knowledge and negative attitude were associated only with having never been given nursing education as their primary university education “Stream 2 students” (p = .012 and p = .01, respectively. These findings have implications for development of teaching strategies and curricular approaches for nursing to address this health care issue.

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

    Full Text Available Background -Risk factors for acquiring hepatitis C virus (HCV infection have been elucidated in many developed countries but the picture is still not clear in many Middle Eastern Countries including Saudi Arabia. Aim -To investigate possible risk factors for acquiring HCV among Saudis. Methods -Various demographic and medical risk factors that might be associated with the spread of HCV among Saudis were investigated. The population studied included 20 anti-HCV-positive with chronic liver disease (CLD, 30 anti-HCV-positive patients without CLD and 272 anti-HCV-negative Saudi blood donors. All people investigated were of the same age group (>40 years of age. Results -None of the demographic parameters studied (type of job, type of housing, education was found to be significantly associated with acquiring HCV infection among our Saudi patients. On the other hand up to 40% of the anti-HCV-positive patients and irrespective of the condition of liver disease had a history of surgery, and 25% of them had a history of multiple injections. Furthermore, at least 20% of our anti-HCV-positive patients had a history of schistosomiasis which is significantly higher than schistosomiasis among the blood donors (P< 0.005. Conclusion -In addition to blood and blood products, schistosomiasis seems to be a possible risk factor for acquiring HCV among the Saudi population. The association between schistosomiasis and enhancement of HCV infection need to be further elucidated.

    On continental to regional scales feedbacks between landuse and landcover change and climate have been widely documented over the past 10-15 years. In the present study we explore the possibility that also vegetation changes over much smaller areas may affect local precipitation regimes. Large scale (˜ 10 5 ha) irrigated plantations in semi-arid environments under particular conditions may affect local circulations and induce additional rainfall. Capturing this rainfall 'surplus' could then reduce the need for external irrigation sources and eventually lead to self-sustained water cycling. This concept is studied in the coastal plains in South West Saudi Arabia where the mountains of the Asir region exhibit the highest rainfall of the peninsula due to orographic lifting and condensation of moisture imported with the Indian Ocean monsoon and with disturbances from the Mediterranean Sea. We use a regional atmospheric modeling system (RAMS) forced by ECMWF analysis data to resolve the effect of complex surface conditions in high resolution (Δ x = 4 km). After validation, these simulations are analysed with a focus on the role of local processes (sea breezes, orographic lifting and the formation of fog in the coastal mountains) in generating rainfall, and on how these will be affected by large scale irrigated plantations in the coastal desert. The validation showed that the model simulates the regional and local weather reasonably well. The simulations exhibit a slightly larger diurnal temperature range than those captured by the observations, but seem to capture daily sea-breeze phenomena well. Monthly rainfall is well reproduced at coarse resolutions, but appears more localized at high resolutions. The hypothetical irrigated plantation (3.25 10 5 ha) has significant effects on atmospheric moisture, but due to weakened sea breezes this leads to limited increases of rainfall. In terms of recycling of irrigation gifts the rainfall enhancement in this particular

    The 1991 Gulf oil spill heavily impacted the coastal areas of the Saudi waters of the Arabian Gulf and recent studies have indicated that even 15. years after the incident, macrobenthos had not completely recovered in the sheltered bays in the affected region such as, Manifa Bay. This study investigates the community conditions of macrobenthos in the open waters in one of the impacted areas, Al-Khafji waters, about 14. years after the spill. Diversity measures and community structure analyses indicate a healthy status of polychaete communities. The BOPA index reveals that oil sensitive amphipods were recolonized in the study area. This confirms that the benthic communities of the oil spill impacted area had taken only <14 years to recover in the open waters of the impacted areas. The study also reveals the existence of three distinct polychaete communities along the depth and sediment gradients. © 2011 Elsevier Ltd.

    The Arabian Peninsula is a key region for understanding climate change and human occupation history in a marginal environment. The Mundafan palaeolake is situated in southern Saudi Arabia, in the Rub' al-Khali (the 'Empty Quarter'), the world's largest sand desert. Here we report the first discoveries of Middle Palaeolithic and Neolithic archaeological sites in association with the palaeolake. We associate the human occupations with new geochronological data, and suggest the archaeological sites date to the wet periods of Marine Isotope Stage 5 and the Early Holocene. The archaeological sites indicate that humans repeatedly penetrated the ameliorated environments of the Rub' al-Khali. The sites probably represent short-term occupations, with the Neolithic sites focused on hunting, as indicated by points and weaponry. Middle Palaeolithic assemblages at Mundafan support a lacustrine adaptive focus in Arabia. Provenancing of obsidian artifacts indicates that Neolithic groups at Mundafan had a wide wandering range, with transport of artifacts from distant sources.

    Air pollution research in Saudi Arabia and the whole of Middle East is at its inception, making air pollution in the region a significant problem. This study presents the first detailed data on fine particulate matter (PM2.5) concentrations of Black Carbon (BC), ions, and trace metals at Rabigh, Saudi Arabia, and assesses their sources. Results showed several characteristic aspects of air pollution at Rabigh. Daily levels of PM2.5 and BC showed significant temporal variability ranging from 12.2 - 75.9 µg/m3 and 0.39 - 1.31 µg/m3, respectively. More than 90% of the time, the daily PM2.5 exceeded the 24 h WHO guideline of 20 µg/m3. Sulfate, NO3-, and NH4+ dominated the identifiable components. Trace metals with significantly higher concentrations included Si, S, Ca, Al, Fe, Na, Cl, Mg, K, and Ti, with average concentrations of 3.1, 2.2, 1.6, 1.2, 1.1, 0.7, 0.7, 0.5, 0.4 and 0.1 µg/m3, respectively. Based on the Air Quality Index (AQI), there were 44% days of moderate air quality, 33% days of unhealthy air quality for sensitive groups, and 23% days of unhealthy air quality throughout the study period. Two categories of aerosol trace metal sources were defined: anthropogenic (S, V, Cr, Ni, Cu, Zn, Br, Cd, Sb, and Pb) and naturally derived elements (Si, Al, and Fe). The extent of anthropogenic contribution was estimated by the degree of enrichment of these elements compared to the crustal composition. Soil resuspension and/or mobilization is an important source of "natural" elements, while "anthropogenic" elements originate primarily from fossil fuel combustion and industries. Ni and V correlated strongly pointing to combustion of heavy fuel oil as the likely source. A positive matrix factorization (PMF) was used to obtain information about possible sources. Our study highlights the need for stringent laws on PM2.5 emission control to protect human health and the environment.

    This paper reviews the current Geographic Information System (Longley et al.) implementation and status in the Kingdom of Saudi Arabia (KSA). Based on the review, several problems were identified and discussed. The characteristic of these problems show that the country needs a national geospatial centre. As a new initiative for a national geospatial centre, a study is being conducted especially on best practice from other countries, availability of national committee for standards and policies on data sharing, and the best proposed organization structure inside the administration for the KSA. The study also covers the degree of readiness and awareness among the main GIS stakeholders within the country as well as private parties. At the end of this paper, strategic steps for the national geospatial management centre were proposed as the initial output of the study.

    Full Text Available The present study explores the relation- ship between the external CSR practices of the organizations and employees’ job satisfaction, employee engagement and organizational cit- izenship behavior in the context of the Saudi banking industry. A positive relationship between CSR and employee job satisfaction, employee engagement and organizational citizenship be- havior related to the organization is observed. However, the organizational citizenship behavior related to individual is found unrelated to CSR. The theoretical foundation of the study is ground- ed in the spirit of social identity theory (Tajfel and Turner, 1979 and social exchange theory (Blau, 1964. The study implies that involvement in ex- ternal CSR may be a determinant for maintaining a motivated and enthusiastic workforce.

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

    Full Text Available The study identified how Saudi schoolteachers perceive reading and comprehension. It also investigated the effect of teachers’ willingness and lesson presentation on learners’ achievement. A descriptive approach was used, and the sample consisted of 56 teachers. The lesson plan in Broughton et al.’s study was adopted as a model lesson plan. Respondents’ responses revealed their poor awareness of the most important activities that facilitate or hinder comprehension. Furthermore, teachers’ willingness and readiness to teach reading were not sufficient to yield competent teachers. It concluded that students were not given sufficient time and assigned to cleverly chosen roles to better understand the text. Teachers, however, should reconsider their daily lesson plans through which reading lessons are executed, taking into account students’ culture, interests, feelings, and so forth. Finally, other researchers were recommended to investigate the differences in students’ achievement levels due to the adoption of the lesson plan proposed by Broughton et al.

    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.

    Full Text Available Approximately 2.4 kbp of mitochondrial DNA was sequenced from 9 individuals of Uromastyx ornata philbyi originating from Taif, Namas, Al-Baha, and Jazan in southwestern Saudi Arabia. The sequenced regions cover eight tRNA genes (tRNAGln, tRNAIle, tRNAMet, tRNATrp, tRNAAla, tRNAAsn, tRNACys, and tRNATyr and two protein-coding genes (NADH dehydrogenase subunit 2 and cytochrome b. U. ornata philbyi had an insertion of 170 bp length between tRNAGln and tRNAIle genes. The first 128 bp of this insertion was similar to the one identified earlier in U. ornata ornata and can be folded into a stem-and-loop structure, which was less stable in U. ornata philbyi than in U. ornata ornata, or the second tRNAGln gene. The next 42 bp of the insertion was unique in U. ornata philbyi and additionally retained a stable stem-and-loop structure. Most base substitutions found in the sequenced genes were synonymous transitions rather than transversions. Tree analyses supported the sister group relationship between the two U. ornata subspecies and divided U. ornata philbyi into two groups: Taif+Namas group in the east of Sarawat and Al-Baha+Jazan group in the west of Sarawat. These molecular data are in agreement with current classification of U. ornata.

    High-resolution tomographic images of the crust and upper mantle beneath Harrat Al-Madinah, Saudi Arabia, are obtained by inverting high-quality arrival-time data of local earthquakes and teleseismic events recorded by newly installed borehole seismic stations to investigate the AD 1256 volcanic eruption and the 1999 seismic swarm in the study region. Our tomographic images show the existence of strong heterogeneities marked with low-velocity zones extending beneath the AD 1256 volcanic center and the 1999 seismic swarm area. The low-velocity zone coinciding with the hypocenters of the 1999 seismic swarm suggests the presence of a shallow magma reservoir that is apparently originated from a deeper source (60-100 km depths) and is possibly connected with another reservoir located further north underneath the NNW-aligned scoria cones of the AD 1256 eruption. We suggest that the 1999 seismic swarm may represent an aborted volcanic eruption and that the magmatism along the western margin of Arabia is largely attributed to the uplifting and thinning of its lithosphere by the Red Sea rifting.

    Metropolitan cities in the Kingdom of Saudi Arabia, as Jeddah and Riyadh, are more frequently experiencing flooding events caused by strong convective storms that produce intense precipitation over a short span of time. The flooding in the city of Jeddah in November 2009 was described by civil defense officials as the worst in 27 years. As of January 2010, 150 people were reported killed and more than 350 were missing. Another flooding event, less damaging but comparably spectacular, occurred one year later (Jan 2011) in Jeddah. Anticipating floods before they occur could minimize human and economic losses through the implementation of appropriate protection, provision and rescue plans. We have developed a coupled hydro-meteorological model for simulating and predicting flooding events in the city of Jeddah. We use the Weather Research Forecasting (WRF) model assimilating all available data in the Jeddah region for simulating the storm events in Jeddah. The resulting rain is then used on 10 minutes intervals to feed up an advanced numerical shallow water model that has been discretized on an unstructured grid using different numerical schemes based on the finite elements or finite volume techniques. The model was integrated on a high-resolution grid size varying between 0.5m within the streets of Jeddah and 500m outside the city. This contribution will present the flooding simulation system and the simulation results, focusing on the comparison of the different numerical schemes on the system performances in terms of accuracy and computational efficiency.

    Objective: To present the histopathological and clinical correlation of mycetoma among patients attending King Abdulaziz University Hospital between 1998-2013.Methods: The data of all histopathologically diagnosed mycetomas in the period between January 1998 and January 2013 were collected through a computerized database search of the anatomic pathology archives at King Abdulaziz University Hospital. The collected data were analysed. Identification of species were performed for five patients using 16 S ribosomal DNA and internal transcribed spacer 2.Results: There were 19 patients with mycetoma with an average age of 44.26 years and male: female ratio of 4:1. Actinomycetoma were 63.15% and eumycetoma were 36.84%. All patients presented with the classic lesions; presenting as painless subcutaneous mass, sinuses and discharge containing grains. The swellings were of slow evolution, with preferential foot localization. Species specification performed for samples from five patients with active lesions revealed species of Actinomyces israelii and Madurella mycetomatis in respective cases.Conclusions: Actinomycetoma is more common than eumycetoma in this region. The fact that one of the patients with eumycetoma was a Saudi national raises the possibility of an indigenous species similar to Maduraella mycetomatis to be further explored for characteristics and pathogenesis. The disease has to be prioritized again and more robust and quick molecular diagnostic tools should be made available in order to save patients form disfiguring amputations.

    Objective: To estimate the risk profile of coronary heart disease (CHD) among the staff members of Qassim University and assess their knowledge in a screening campaign in Qassim region, Saudi Arabia. Methods: A cross-sectional study was conducted among male and female staff at Qassim University campus. All employees of Qassim University were invited to participate in the study. Data were collected through a self-administered questionnaire. The study sample size was 233 staff and employees. The data were entered and analyzed using SPSS version 18. The data analysis focused on providing point estimates for the risk factors. Results: The study found that 30% of participants have one or more risk factors for CHD, namely obesity 20.6%, diabetes 10.3%, hypertension 12.4%, dyslipidemia 10.7%, and smokers (11.6%). About 54% of the participants have a family history of at least one chronic disease as a risk factor for CHD. Conclusion: The most common risk factor of CHD among the staff members is obesity by 20.6%. Risk factors for CHD are quite common among Qassim University staff. These findings need to increase the health education and disease promotion program as an important intervention to reduce the occurrence and severity of CHD risk factors and to improve the quality of the life of the staff members of Qassim University.

  11. Fish market surveys indicate unsustainable elasmobranch fisheries in the Saudi Arabian Red Sea

    Elasmobranch populations worldwide are severely threatened due to overexploited and unregulated fisheries. Despite the fact that sharks and rays are captured in fisheries operating along the Red Sea coast of the Kingdom of Saudi Arabia (KSA), information on any aspects of these fisheries are very limited. Here we document the structure, composition and biological characteristics of eastern Red Sea elasmobranch fisheries based on genetic identification and market survey data over an intensive two-year sampling period at the biggest Red Sea fish market in the KSA (Jeddah). Market surveys conducted two times per month between 2011 and 2013 revealed that 24 previously confirmed elasmobranch species for the Red Sea were landed by fishers and offered for sale. Genetic identification revealed two potentially undescribed guitarfish species as well as four batoid species not formerly reported from the Red Sea. Five coastal carcharhinid species dominated the landings-. Carcharhinus sorrah, C. amblyrhynchos, C. falciformis, C. limbatus, Rhizoprionodon acutus, together comprising 73% numerically of the total catch. Targeted shark fisheries reportedly exist in shark nursery areas. Most elasmobranchs outside of these areas were reportedly landed as bycatch. Most strikingly, the large majority of landed elasmobranchs were immature males or females below their reported size of sexual maturity, which suggests potential for both growth and recruitment overfishing and emphasizes the urgent need to implement region-specific management and conservation strategies to avoid the loss of these critical predators.

  12. Experimental Measurement of Diffusive Extinction Depth and Soil Moisture Gradients in Southwestern Saudi Arabian Dune Sand

    KAUST Repository

    Mughal, Iqra

    2013-05-01

    In arid lands, a major contribution to water loss is by soil water evaporation. Desert sand dunes in arid regions are devoid of runoff and have high rates of infiltration. Rainwater is commonly stored within them because of the low permeability soils in the underlying desert pavement. In such cases, moisture is confined in the sand dune below a depth, termed as the “extinction depth”, where it is protected from evaporation during long dry periods. Moreover, desert sand dunes have sparse vegetation, which results in low transpiration losses from the stored water. The water accumulated below the extinction depth of the sand dunes can be utilized for various purposes such as in irrigation to support desert agriculture. In this study, field experiments were conducted in Western Saudi Arabia to monitor the soil moisture gradients and determine the diffusive extinction depth of dune sand. The dune sand was saturated with water and was exposed to natural conditions (evaporation and precipitation). The decline of the water level in the sand column was continuously recorded using transducers and sensors installed at different depths monitored the temporal variation of temperature and moisture content within the sand. The hydrological simulator HYDRUS-1D was used to construct the vertical profiles of soil water content and temperature and the results obtained from HYDRUS-1D were compared to the gradients monitored by the sensors.

    The purpose of this study was to determine the prevalence, etiology and risk factors of treated end-stage renal disease (ESRD) in the region of Tabuk, Saudi Arabia. We studied 460 renal replacement therapy patients through a review of medical records and patient interviews and obtained patient demographics, family history, risk factors for ESRD, environmental exposure to toxins, work conditions, social history and causes of death. The estimated prevalence of treated ESRD was 460 per million populations (PMP); 350 (76%) were treated by hemodialysis, 30 (7%) by peritoneal dialysis and 80 (17%) by kidney transplantation. The mean age was 48 ± 17 years, body mass index was 25 ± 2 kg/m 2 and the male vs. female ratio was 64% vs. 36%. Most patients (55%) were living in rural areas. Etiology of the ESRD was unknown in 33%, hypertension in 24%, chronic glomerulonephritis in 8%, obstructive uropathy in 3.5%, analgesic nephropathy in 5%, Bilhaziasis in 0.5%, chronic pyelonephritis in 2% and diabetic nephropathy in 18%. Other causes such as gouty nephropathy, collagen diseases, toxemia of pregnancy and lupus nephritis constituted 6% of the cases. We conclude that the epidemiology of the treated ESRD in Tabuk area is similar to that in Egypt, but very different from that in the United States.

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

    The purpose of this study was to survey left-handed (LH) dental students and interns concerning whether they face any problems in their dental education or in their practice of dentistry. The questionnaires were distributed in four dental colleges in different regions in Saudi Arabia. The questionnaire was comprised of sixteen questions to assess the following issues: demographic information, difficulties in dental school or dental practice due to left-handedness, preferred hand in performing different dental procedures, and musculoskeletal complications. The study found that the percentage of LH dental students was around 7 percent (110 out of 1,660). More than half of these participants (n=56) reported that being LH is not a problem in general, while when performing the required dental work, around 51 percent (n=56) agreed to having a problem. The majority (68 percent; n=75) reported that they had a problem with having RH instructors, and 84.5 percent (n=93) responded that their institution is not properly equipped to accommodate LH students. Only 34 percent (n=37) agreed that using facilities of an RH dentist may cause musculoskeletal complications to an LH dentist. The results of this study suggest that dental schools should provide LH students with appropriate equipment and a proper learning environment.

    Full Text Available Introduction and Objectives: Bronchiectasis is a pulmonary manifestation that often occurs in individuals with rheumatoid arthritis (RA. Nevertheless, the prevalence of bronchiectasis in RA patients and predictors of its development/progression remain ill-defined. Our objective was to investigate the prevalence of bronchiectasis in a group of RA patients and examine possible clinical or biochemical risk factors that might contribute to its development. Methods: This was an observational study analyzing 100 RA patients with no pulmonary symptoms selected from King Abdulaziz University Hospital in the Western region of Saudi Arabia from October 2013 to 2014. Demographic, clinical and laboratory information were collected for all patients. Diagnosis was based on the 2010 American College of Rheumatology (ACR/European League Against Rheumatism (EULAR classification system, and disease activity was assessed using the 28-Joint Disease Activity Score Index with C-reactive protein; high-resolution computed tomography chest scans were performed. The prevalence of bronchiectasis was recorded and its association with different risk factors was examined using standard statistical methods. Results: All 100 patients fulfilled the ACR and EULAR classification criteria for RA diagnosis. Their mean age was 51.05 ± 13.5 years, disease duration was 6.19 ± 6.4 years and disease activity index was 4 ± 1.3 (moderate activity. A total of 35 (35% patients developed bronchiectasis. Notably, we observed significant positive associations of bronchiectasis with age, disease duration and male gender (P < 0.001, P = 0.006, P = 0.028, respectively. Conclusions: Asymptomatic bronchiectasis represents a common complication in moderately active RA patients within the Western Region of Saudi Arabia. Furthermore, several predictors of bronchiectasis development were identified, which can contribute to effective risk stratification in RA patients. Further prospective studies are

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

A self-administered anonymous questionnaire was designed to gather information on the preferred assessment method for course achievement. The preferred methods were also evaluated in relation to cognitive functions. Preference for specific exam format, in the form of multiple choices, short essay questions, or both, and the stated reasons for that preference, was also included in the questionnaire.Results: Out of 310 questionnaires distributed, 238 were returned. Written tests, projects, portfolios, and take home exams were the preferred modes for assessing students’achievements in a course; oral tests including a viva voce were the least preferred type of assessment. Questions that tested the domains of ‘understanding’ and ‘application’ were the most preferred type while those entailing ‘analysis’ were the least preferred. Multiple choice question format was the most preferred type of question (68.7% at both pre- and clinical stages.Conclusion: Students’ assessments at the College of Medicine, King Faisal University, Saudi Arabia, do not use the full range of cognitive domains. The emphasis on higher domains for medical students’ assessment incorporating critical thinking should increase as the students’ progress through their medical courses.Keywords: medical students, assessment, exams, multiple choices, essay

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

  1. Evaluation of TRMM satellite-based precipitation indexes for flood forecasting over Riyadh City, Saudi Arabia

    Floods are among the most common disasters harming humanity. In particular, flash floods cause hazards to life, property and any type of structures. Arid and semi-arid regions are equally prone to flash floods like regions with abundant rainfall. Despite rareness of intensive and frequent rainfall events over Kingdom of Saudi Arabia (KSA); an arid/semi-arid region, occasional flash floods occur and result in large amounts of damaging surface runoff. The flooding of 16 November, 2013 in Riyadh; the capital city of KSA, resulted in killing some people and led to much property damage. The Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA) Real Time (RT) data (3B42RT) are used herein for flash flood forecasting. 3B42RT detected high-intensity rainfall events matching with the distribution of observed floods over KSA. A flood early warning system based on exceedance of threshold limits on 3B42RT data is proposed for Riyadh. Three different indexes: Constant Threshold (CT), Cumulative Distribution Functions (CDF) and Riyadh Flood Precipitation Index (RFPI) are developed using 14-year 3B42RT data from 2000 to 2013. RFPI and CDF with 90% captured the three major flooding events that occurred in February 2005, May 2010 and November 2013 in Riyadh. CT with 3 mm/h intensity indicated the 2013 flooding, but missed those of 2005 and 2010. The methodology implemented herein is a first-step simple and accurate way for flash flood forecasting over Riyadh. The simplicity of the methodology enables its applicability for the TRMM follow-on missions like Global Precipitation Measurement (GPM) mission.

    Full Text Available Introduction: Oral malodor or halitosis is a common problem in the general population throughout the world. Results of previous research findings suggest that there is a relationship between oral malodor and social anxiety disorder. Halitosis can be very damaging to someone psychologically due to the social stigma. In this study, we tried to assess the social stigma related to halitosis and compare that in Saudi and British population. Methodology: A pretested questionnaire was distributed among Saudi and British population. Responses were obtained from 308 (Kingdom of Saudi Arabia and 304 (United Kingdom participants. The purpose of this study was explained to the participants before distributing questionnaire form and the information was collected accordingly. Results: A total of 612 participants, 308 (Jeddah and Abha and 304 (Cardiff, Edinburgh, and Glasgow were selected and all the participants were aware of their halitosis. Selected Saudi population assessed their halitosis as mild (50.6%, moderate (30.12% and severe (19.28%. Selected British population assessed their halitosis as mild (39.71%, moderate (36.76%, and severe (23.53%. 71.2% of the Saudi population selected and 56.6% of the United Kingdom population selected responded that they encountered individuals with halitosis. 76.9% of Saudi population selected and 55.8% of United Kingdom population selected encountered social embarrassment due to halitosis. Conclusion: Considerable amount of stigma associated with halitosis persists in both countries. Though there are no significant differences in the social stigma attached with halitosis between the United Kingdom and Kingdom of Saudi Arabia, it is still a matter of concern.

    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.

    Nurse residency programs have been adopted by health care organizations to assist new graduate nurses with daily challenges such as intense working environments, increasing patient acuity, and complex technologies. Overall, nurse residency programs are proven beneficial in helping nurses transition from the student role to independent practitioners and bedside leaders. The purpose of this study was to assess the impact of residency programs on leadership skills of new Saudi graduate nurses who completed a residency program compared to new Saudi graduate nurses who did not participate in residency programs. The study design was cross-sectional involving a convenience sample (n = 98) of new graduate nurses from three hospitals in Saudi Arabia. The Clinical Leadership Survey was used to measure the new graduate nurses' clinical leadership skills based on whether they completed a residency program or not. Descriptive statistics, correlation, and multiple linear regression analyses were conducted to examine leadership skills in this sample of new Saudi graduate nurses. A significant difference was found between residents and nonresidents in their leadership skills (t = 10.48, P = .000). Specifically, residents were significantly more likely to show higher levels of leadership skills compared to their counterparts. Attending a residency program was associated with a significant increase in clinical leadership skills. The findings of this study indicate that there is a need to implement more residency programs in hospitals of Saudi Arabia. It is imperative that nurse managers and policy makers in Saudi Arabia consider these findings to improve nurses' leadership skills, which will in turn improve patient care. Further research should examine how residency programs influence new graduate nurses' transition from student to practitioner with regard to clinical leadership skills in Saudi Arabia.

    A total of 157 environmental samples were collected from 11 ecological regions across Saudi Arabia to isolate native Bacillus thuringiensis (Bt) strains. Bt isolates (n=103) were recovered by the 50% (v/v) ethanol treatment method with Bt index range of 0.01 to 0.4. Most of Bt isolates showed spherical crystals (54%), while, irregular, bi-pyramidal, and spore-attached crystal constituted 27, 16 and 3% respectively. PCR analysis with eight general and specific dipteran primers of Cry and Cyt genes, revealed positive amplification for cry4 & cyt1, and cry4A, cry4B and cyt2, and cry 10 and cry 11 genes in 28%, 26%, 22%, and 25% of tested strains respectively; whereas cry2 gene was not detected except with the reference Bt kurstaki HD-1 strain. Bioassays against Aedes caspuis and Culex pipiens larvae indicated that 11 strains displayed better larvicidal activity compared with Bacillus thuringiensis H14 (Bti) reference (LC50 0.6 μg/ml) strain against Ae. caspuis, but only two strains (620A & 633R1, LC50 of 0.09 μg/ml & 0.064 μg/ml) that gave significant enhancement. Additionally, one strain (633R1) showed LC50 similar to that of Bti H14 (LC50 0.064 μg/ml) against Cx. pipiens. With the exception of cyt primers, sequenced DNA of all positive primers amplicons revealed 95 to 99% identity in GenBank with Bacillus thuringiensis subsp. israelensis plasmid pBtoxis and also correlated with its SDS-PAGE expressed protein profiles analysis. It is hoped that our wild bio-insecticide Bt strains can be explored in future in the control of mosquito-vector borne diseases in Saudi Arabia.

  16. Multi-decadal classification of synoptic weather types, observed trends and links to rainfall characteristics over Saudi Arabia

    An automated version of the Lamb weather type classification scheme was employed to characterize daily circulation conditions in Saudi Arabia from 1960 to 2005. Daily gridded fields of sea level pressure (SLP) from both the NCEP/NCAR and the European Center for Medium-Range Weather Forecast (ECMWF) reanalysis data (ERA40) were used as input data for this classification. The output catalog included 10 basic types, which describe the direction and vorticity of airflow in the region (i.e., cyclonic, anti-cyclonic, and directional). In general, our findings indicate that cyclonic (C) days represent the most frequent type among all days, with 69.2% of the annual count of days from 1960 to 2005, followed by SE directional flows (21%). It was also determined that airflows originating from the Indian Ocean (i.e., S, SE, and E) are more frequent than those from the Mediterranean and Red Seas (i.e., W, NW, and SW). The defined weather types were assessed for the presence of inter-annual and intra-annual trends using the Mann–Kendall tau statistic. The trend analysis suggests statistically significant changes in the frequencies of a majority of the weather types from 1960 to 2005. The relationship between the daily occurrence of rainfall and the frequency of individual weather types was also described using daily rainfall data from a network of 87 weather observatories. Results demonstrate that increasing frequencies of weather types connected to easterly inflows support higher precipitation amounts over the study domain. Characterizing the association between atmospheric circulation patterns and rainfall in Saudi Arabia is important for understanding potential impacts related to climate variability and also for developing circulation-based downscaling methods.

    Full Text Available This study sought to investigate Saudi parents’ attitudes towards using English as a medium of instruction (EMI in private primary schools.The study also attempted to find the reasons why Saudi parents prefer EMI private schools for their children. Additionally, it examined the effects of using EMI on children’s Arabic language and culture, and their educational achievement in the next levels. The sample was 68 Saudi parents who have their children in a private primary school. The study used a questionnaire for data collection. It used a mixed design since data were analyzed using both quantitative and qualitative methods. Quantitative data were analyzed through statistical analysis (SPSS while qualitative data were analyzed through content analysis using the categorization of themes. The results of this study showed that Saudi parents have positive attitudes towards using EMI in international private primary schools. Many Saudi parents prefer to send their children to EMI private primary schools, because they realize the importance of English as an international language, which can provide better opportunities for their children in the future. Also, they prefer to send their children to these schools, where English is used as a medium of instruction, because it is more effective if the child learned the language at an early age. However, some parents expressed a belief that English has negatively affected their children’s Arabic language.

    Full Text Available This study aims at describing the system of SPA (Saudi pidginized Arabic as produced by AFEs (Asian foreign expatriates working in Saudi Arabia with specific reference to universal characteristics of reduction and simplification in the system of morpho-syntactic structure of Saudi Arabic. The study is based on data collected through a semi-structured interview technique probing into the features of SPA system. Thirty informants were randomly selected from among expatriates working in Saudi Arabia and belonging to different linguistic backgrounds – Urdu, Hindi, Bengali, Tagalog, Indonesian, and Malayalam- as representatives of AFEs. The study showed that the AFEs tend to use simplified and reduced system of SA in order to communicate with its native speakers. This was reflected in producing variations of sentence word order that are not compatible with the sentence word order of SA, reduced inflectional verb forms and simplified noun phrase lacking agreement within its structure. The study concluded with the following implications: 1 SPA could be considered as an emerging contact variety among Asian expatriates in Saudi Arabic; 2 it has universal characteristics of reduction and simplification as shown in its structural system; 3 substrate languages play an essential role in the formation of the SPA.Keywords: Pidgin, simplification, reduction, SPA, AFEs, SA.

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

    Full Text Available Egypt is one of the important orange exporters and Saudi Arabia also is an important import orange market. The Saudi orange market is a main market for Egypt which has a market share that exceeds half of Saudi orange market by 55.72%. This article aims to discover the degree of market power for Egyptian orange exports and other competitors in the Saudi market and if it is considered a measure of the relative mark- up by applying Residual Demand Elasticity approach. The results show that Egyptian orange exports has just a statistically signified market power by SUR and 3-SLS and has a negative sign, which may gain monopolistic profits by the relative mark-up over its marginal cost by about 63.7% without losing any of its market share. The source of Egyptian orange exports market power is due to: 1- product differentiation where Egypt exports navel orange most its export season compared with sweet orange which exported from other competitors. 2- Saudi Arabia Market demand characteristics which reflect on the consumers preference for Egyptian oranges.

    Mothers' instigation of complementary feeding before their infant reaches 6 months old risks shortening their breastfeeding duration, and high morbidity and mortality for their child. Complementary feeding practices require further investigation in Saudi Arabia. The present study aims to evaluate complementary feeding practices, and to establish which factors are associated with the early introduction of complementary feeding in the Saudi Arabian context. Cross-sectional research was conducted with 632 mothers of infants aged between 4 and 24 months attending five primary health care centers (PHCCs) between July and December 2015 in Saudi Arabia.

    Despite the increasing number of medical articles being published from the Middle East, clinical research is still lagging behind compared to other regions. Enrolling participants into clinical trials presents an important challenge. We wanted to explore the perception, knowledge, and willingness of cancer patients to participate in oncology clinical trials and to recommend strategies to overcome these challenges. A 31-item questionnaire was administered to cancer patients and their family members in an outpatient clinic. Two hundred four patients and family members were enrolled between December 2011 and February 2013. Fifty-eight percent of the participants were aware of clinical trials. Some misconceptions included the following: 22% believed that no clinical trials were conducted in the Arab world, 19% believed that clinical trials in the Arab world were not under any regulatory authority supervision, and 15% believed that local clinical trials are conducted on subjects without their consent. One third of patients assumed that clinical trials are executed on animals instead of humans, and greater than 40% believed that clinical trials are performed for new medications only. Finally, 61% of the survey participants who were aware of clinical trials expressed their willingness to participate in trials. This large cohort survey demonstrated that a relatively significant number of Saudi cancer patients and their families are aware of clinical trials and a similarly high number of participants are willing to participate in clinical trials. This leads us to believe that patients' awareness and perception of clinical trials are not a significant limiting factor in clinical trial recruitment in our region.

    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

    Full Text Available 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

    Cosmetics are one of the most important sources of releasing heavy metals. Different varieties of chemicals are used in cosmetic products as ingredients and some are used as preservatives. There are concerns regarding the presence of harmful chemicals in these products. Among the harmful chemicals, cosmetic products contain heavy metals. The present study was conducted to determine the content of certain heavy metals in the products made in different countries and marketed in Saudi Arabia. Thirty-one products of different brands or misbrands of commonly used cosmetic products (hair cream, beauty cream, skin cream, hair food formula, hair gel, whitening daily scrub, shampoo, shower gel, body care, body lotion, hand wash, daily fairness, shaving cream, toothpaste, germ and beauty soap, and cream soap) were purchased from local markets of Saudi Arabia. Samples were analyzed to determine the concentrations of ten metals (lead, aluminum, cadmium, cobalt, chromium, copper, manganese, nickel, mercury, and arsenic) using inductively coupled plasma mass spectrometer (ICP-MS). Based on the maximum concentrations, the heavy metal contents were arranged in the following decreasing order: Al > Cu > Mn > Pb > Cr > Ni > Hg > Co > As > Cd in cream products, Al > Pb > Cu > Cr > Mn > Ni > Hg > As > Co > Cd in shampoo products, Al > Cu > Pb > Cr > Mn > Ni > As > Co > Hg > Cd in soap products, and Al > Cu > Mn > Pb > Cr > Co > Ni > Cd > As > Hg in toothpaste products. Since the metal concentrations may relate to specific brands, product type, color, or cost, industrialist would have to check the raw materials before they are gathered into the final products to track the source of these contaminants.

    Full Text Available Problem statement: Yield crop cultivars and landraces are valuable sources of genetic variations that the knowledge and implication of these variations are critical in the plant breeding programs. our major objective of this study is investigating the discriminating capacity of RAPD, ISSR and SSR markers and of their effectiveness in establishing genetic relationship and diversity among Egyptian and Saudi wheat cultivars. Approach: Eleven wheat cultivars and landraces collected from Egypt and Saudi Arabia, five Egyptian wheat (Sakha 93, Sods 1, Sods 4, Gmiza 9 and Sohag 3 and six Saudi wheat landrace cultivars (Hmees, Al-Kaseem, Hegazi, Abo-Sakr, Dubai 1 and Nagran were characterized using RAPD, ISSR and SSR molecular markers as efficient tools. Ten and nine oligonucleotide primers of RAPD and ISSR respectively and four primer pairs of SSR were used in wheat samples analysis. Only clear and repeatable band profile of 6 RAPD, 8 ISSR and 2 SSR primers were obtained. In RAPD analyses, 74 out of 141 bands (52% were polymorphic. Results: The number of alleles ranged from 8-21 per primer, with an average of 14.1 per primer. In ISSR analyses, a total of 78 alleles were detected, along with 36 alleles (46% were polymorphic. The number of alleles per primer ranged from 5-10 with an average of 8.6 alleles per ISSR primer. SSR reactions recorded 6 alleles, of which 5 alleles (83% were polymorphic. Cluster analysis was conducted using Unweighted Pair Group Method that depends on Arithmetic Average (UPGMA. The dendrogram cluster diagram classified the evaluated genotypes in three major clusters corresponding to the cultivation regions. The first group contains Sakha 93, Sods 1 and Sods 4 with more than 80% Genetic Similarity (GS. The GS between Sakha 93 and Sods 1, Sakha 93 and Sods 4 or Sods 1 and Sods 4 were 83.6%, 83.9 and 85.4 respectively. The second group contains Gmiza 9 and Sohag 3 with GS 83.1%. The third group contains most of the Saudi landrace

    Venous thromboembolism (VTE), including deep vein thrombosis (DVT) and pulmonary embolism (PE), is a preventable disease. Long distant travelers are prone to variable degree to develop VTE. However, the low risk of developing VTE among long-distance travelers and which travelers should receive VTE prophylaxis, and what prophylactic measures should be used led us to develop these guidelines. These clinical practice guidelines are the result of an initiative of the Ministry of Health of the Kingdom of Saudi Arabia involving an expert panel led by the Saudi Association for Venous Thrombo Embolism (a subsidiary of the Saudi Thoracic Society). The McMaster University Guideline working group provided the methodological support. The expert panel identified 5 common questions related to the thromboprophylaxis in long-distance travelers. The corresponding recommendations were made following the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. PMID:28042639

    Full Text Available This study explores the adoption of mobile banking practices in Saudi Arabia. It focuses on the existence of sufficient infrastructure, and the possible challenges that m-banking services may face. Also, discovers the potential opportunities in the country. A sample of banks in Saudi Arabia was surveyed via questionnaire, with a particular focus on the staff in the related IT departments. The findings demonstrate that although m-banking is believed to be important, there is a general lack of awareness, and it is still not widely accepted by the public. M-banking services provided should be easier to use and offer more security to its users. Furthermore, findings reveal that cooperation among the concerned parties is currently not extensive. From this, the researcher recommends that governing regulations and policies should be properly identified and put in place, and proposes that banking decision-makers in Saudi Arabia should reevaluate their bank’s strategic plans.

    We evaluated the documentation of ethical conduct (obtaining institutional review board approval and consent and following ethical guidelines) of human subject research studies published in Saudi Arabian medical journals between 1979 and 2007. Studies were classified as retrospective, prospective noninterventional, interventional or survey/interview. Of 1838 studies published in 286 journal issues of 11 Saudi Arabian medical journals, only 0.9% documented the ethical guidelines followed, with a significantly higher rate for studies published after year 2000 (1.7%). Of 821 studies requiring institutional review board approval, 8.6% documented obtaining the approval and informed consent, with a significantly higher rate for interventional studies (19.4%), post-year 2000 studies (19.7%) and studies performed outside Saudi Arabia (15.9%). The low documentation rate suggests editor's lack of rigor and/or investigators' ignorance of guidelines. The higher documentation rate after year 2000 suggests an ongoing improvement.

    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.

    Zielsetzung: In der Studie sollten die Kenntnisse, die Einstellung und die praktische Umsetzung infektionspräventiver Maßnahmen bei Studenten der Zahnmedizin analysiert werden.Methode: In einer Querschnittsstudie wurde ein selbst zu beantwortender Fragebogen zur Erfassung des Impfstatus, der Kenntnisse und der Einstellung zur Infektionsprävention an 600 Studenten im 4., 5. und 6. Ausbildungsjahr des Al-Farabi College für Dentistry und Nursing, Riyadh, Saudi Arabia, verschickt. Die Daten wurden mittels SPSS analysiert. Das Signifikanzniveau wurde mit p<0,05 festgelegt.Ergebnisse: Die Responserate betrug 85% (512 von 600). Während die Mehrzahl der Studenten (90%) gegen Hepatitis B geimpft war, war nur bei 37,4% anti-HBs bestimmt worden. 98,8% bzw. 90,8% trugen stets Schutzhandschuhe bzw. Mund-Nasen-Schutz bei der zahnärztlichen Behandlung, während das Tragen einer Schutzbrille nur in 29,2% angegeben wurde. Ein signifikant höherer Anteil der Studenten zeigte im 6. Ausbildungsjahr eine positive Einstellung zur Behandlung von Patienten mit Infektionskrankheiten im Vergleich zum 4. und 5. Ausbildungsjahr. Etwa ein Drittel der Studenten gab an, dass sich ein oder mehrere arbeitsbedingte Verletzungen bei der Patientenbehandlung ereignet hatten.Schlussfolgerung: Obwohl die Studenten ein solides Wissen und eine gute Einstellung zur Infektionsprävention hatten, war die Compliance zur praktischen Umsetzung gering. Die Ergebnisse unterstreichen die Notwendigkeit der kontinuierlichen Erziehung Saudischer Zahnmedizinstudenten zur Infektionsprävention.

    AIM: The aim of this study was to study the clinical characteristic of patient with refractory asthma (RA) from Saudi Arabia. METHODS: This paper prospectively studied in a university hospital factors leading to RA in a cohort of patients who have inadequately controlled asthma or with frequent exacerbations despite optimum controller therapy. It also studied patients with asthma that requires extended periods of oral steroids to control. RESULTS: The mean age was 45.1 years (±9.1) where 74 patients were enrolled in this study with the age group (37–48 years) is having the highest percentage (64.8%). Female patients represented 62.2%. The two major comorbid conditions were allergic rhinitis (54.1%) and gastroesophageal reflux (33.8%). The vast majority (72 patients) had at least one trigger factor for asthma (97.3%). The asthma control test showed that 86.4% had an uncontrolled status. Spirometry showed mild disease in 9.5%, moderate in 47.3%, and severe in 43.2%. Eosinophilia was seen in only 16.2%. Immunoglobulin E level between 70 and 700 μg/L was found in 58.1% of patients. CONCLUSION: RA has certain clinical characteristics and associated comorbid conditions as well as precipitating factors that facilitate the identifications of these cases. PMID:28197221

    2003-01-01

    Breastfeeding is the ideal and most natural way of nurturing infants. The importance of breastfeeding has been proved unequivocally, and UNICEF and WHO have issued guidelines to ensure breastfeeding. Saudi Arabia is a country where the legislation is derived from the Quran and Hadiths. The Holy Quran says that the mothers shall give suck to their offspring for two complete years.... The majority of mothers start breastfeeding their infants but soon introduce bottles. The single most common reason cited for the early introduction of bottle feeding is that the breast milk is insufficient. Because of this tendency, many mothers practice mixed feeding. The duration of breastfeeding varies but in general it is done beyond six months, and various factors affect the duration. Researchers have recently started using the WHO recommended key breastfeeding indicators. In a study these key indicators were found to be very low. The authors feel that there is a need to revise the media campaign for promoting breastfeeding utilizing the instructions and guidance from the Holy Quran and Hadiths.

    Aim The aim of this study was to evaluate the use of the London Atlas of Human Tooth Development and Eruption for age estimation in Saudi Arabian children and adolescents (aged 2–20 years), for forensic odontology application. Materials and methods This cross-sectional survey analyzed orthopantomograms (OPGs) of the complete dentition (including root development) to estimate the deviation from chronological age. Each OPG was de-identified and analyzed individually and classified into age-groups by the lead author, using the methods of the Atlas of Tooth Development. Results OPGs from a total of 252 patients [110 (44%) males, 142 (56%) females] aged 2–20 years (24–240 months) were examined in this study. The average estimated and chronological ages of subjects differed significantly p 12 months. Conclusion This study, conducted in a sub-population of different origin than the UK sample used for the development of the London Atlas, identified variation in age estimates that may have significant impacts on results. The establishment of a composite international repository of atlas-based data for diverse ethnic sub-populations would be of great value to clinicians across the globe. PMID:26236126

    Full Text Available The present study targeted health care workers (HCWs in Governmental Hospitals and Primary Health Care Centers in Abha City, southwestern Saudi Arabia. An anonymous self-report questionnaire was used to assess tobacco use and the reasons for smoking. The present study included 736 HCWs. The overall prevalence of tobacco use amounted to 26.3% (14.8% current and 11.5% former users. In a binary logistic regression analysis, males were found significantly more prone to smoke compared to females (aOR = 3.081, 95% CI: 2.004–4.739. Similarly, parental history of tobacco use was found to be a significant risk factor (aOR = 1.540, 95% CI: 1.040–2.278. Among current users, 89.9% were interested in quitting and 66.1% tried before to quit. The prevalence of smoking among HCWs in the present study, besides being a public health problem, represents a potential barrier in involving this group as a first line for tobacco control. There is a need for a national intervention programme in the country in a tailored manner for HCWs to control tobacco use parallel to the running national program for public. These interventions should begin early in basic medical education and to be applied continually during one’s medical career.

    For a detailed characterization of a reservoir, core-log integration is essential. In this paper, data integration from logs and cores of a Saudi Arabian sandstone reservoir is discussed with particular attention to effects of clay on resistivity logs and water saturation. There are four sources of data, namely, core resistivity measurement, clay study from cores (XRD, CEC), spectral core gamma ray, and well logs. In order to generate continuous cation exchange capacity (CEC) with depth, spectral gamma ray measurements (both from core and downhole log) and CEC from cores and correlated. Q{sub v} (CEC per unit pore volume) values are calculated utilizing only well logs by applying Waxman-Smits equation in water bearing zone. Log derived Q{sub v} values from water zone were then correlated with porosity to generate Q{sub v} values in the oil column and compared with core derived Z{sub v}. Finally, data from well logs (porosity, resistivity and Q{sub v}) and cores (resistivity parameters m, n, and Q{sub v}) were integrated for more accurate water saturation calculation. The core-log correlation can be applied to other wells avoiding expensive core analysis, and the technique developed in this project can be used in other sandstone reservoirs.

    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.
