    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.

  3. Irrigated Agriculture, Saudi Arabia

    NASA Technical Reports Server (NTRS)

    1990-01-01

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

    Samples were collected from southern, central and eastern regions of Saudi Arabia using Malaise traps and sweep nets. Nine species of Tabanidae were identified, two for the first time from Saudi Arabia, Hybomitra peculiaris (Szilády) and Atylotus pulchellus (Loew). Therefore, the total number of Tabanidae in Saudi Arabia is 31 species. Remarks of the species recorded in this study were given. A key to the genera of Tabanidae occurring in the Arabian Peninsula is also provided. Available literature for Saudi Arabian Tabanidae is summarized and provided. It is concluded that the tabanid fauna of Saudi Arabia is more similar to that of the Palaearctic region than to the Afrotropical region. PMID:23961046

    The aim of this study was to determine the risk factors of skin disorders among female schoolchildren in primary and intermediate schools in Al-khobar city, Eastern Saudi Arabia. This is a cross-sectional study conducted in Al-Khobar city during the period of January to March 2003. It involved 2239 female schoolchildren randomly selected from 30 regular public and private primary and preparatory schools. A multi-stage stratified random sampling technique with proportional allocation was used. Data was collected using a pre-designed structured questionnaire and clinical examination. Dandruff was negatively associated with private schools and positively associated with age, body mass index and overcrowding. The association of atopic dermatitis with family history of atopy and bronchial asthma was documented in this study. Those who were at high risk of getting acne were schoolchildren who had more baths per week and lived in villas with a high number of rooms (in other words the high socioeconomic class). Pediculosis had a negative association with a high level of father education and high socioeconomic status and a positive association with living in a flat and the number of siblings. It was concluded that sex, socioeconomic status, family history, parents' education, home type, and overcrowding were found to be risk factors for some skin disorders. Accordingly, it is recommended that a preventive health education program for schoolchildren with different levels of skin diseases be started considering the predictive variables that increase the prevalence of these diseases.

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

    Background. The objective of this study was to estimate trends in ectopic pregnancies (EP) in a tertiary care center of Eastern Saudi Arabia. Method. Information about patients with ectopic pregnancies who had been admitted to King Fahd Hospital of the University, AlKhobar, between January 2000 and 31 December 2011 was collected from a computerized hospital registry. Age-specific ectopic pregnancy incidence was calculated. The data was analyzed using SPSS (Statistical Package for the Social Sciences), version 14.0 (Chicago, IL, USA). Results. There were 274 EPs during the study period; the yearly incidence in terms of 24,098 deliveries was 1.19%. The average age was 28.99 Å 5.62 years. During a three-year period (2000–2002), the incidence was 0.92%; from 2003 to 2005, the incidence was 1.01%; from 2006 to 2008, the incidence was 1.51%; and from 2009 to 2011, the incidence was 1.35%. Age-adjusted ectopic pregnancy incidence rates steadily increased from 92.23 per 10,000 women years during the period 2000–2002 to 149.408 during the 2006–2008 period; since then, it has declined to 110.313 per 10,000 women years. Conclusions. Our study reveals that the incidence of EP has decreased from what it had been during the mid-2000s but has remained significantly elevated when compared to the early 2000s.

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

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

    Antimicrobial resistance (AMR) is increasingly being highlighted as an urgent public and animal health issue worldwide. This issue is well demonstrated in bacteria that are resistant to last-line antibiotics, suggesting a future with untreatable infections. International agencies have suggested combating strategies against AMR. Saudi Arabia has several challenges that can stimulate the emergence and spread of multidrug-resistant bacteria. Tackling these challenges need efforts from multiple sectors to successfully control the spread and emergence of AMR in the country. Actions should include active surveillance to monitor the emergence and spread of AMR. Infection prevention and control precautions should also be optimized to limit further spread. Raising awareness is essential to limit inappropriate antibiotics use, and the antibiotic stewardship programs in hospital settings, outpatients, and community pharmacies, should regulate the ongoing use of antimicrobials.

    The status of rheumatoid arthritis (RA) in Saudi Arabia (SA) was examined from various perspectives based on a systematic literature review and the authors’ personal experiences. In this regard, database and journal search were conducted to identify studies on RA in SA, yielding a total of 43 articles. Although efforts have been made to promote RA research in SA, current studies mostly represent only a few centers and may not accurately portray the national status of RA care. Notably, biological therapies were introduced early for almost all practicing rheumatologists in SA (government and private). However, no national guidelines regarding the management of RA have been developed based on local needs and regulations. Also, while efforts were made to establish RA data registries, they have not been successful. Taken together, this analysis can contribute to the planning of future guidelines and directives for RA care in SA. PMID:25491208

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

    2014-01-01

    Aim of the Study: The complex hospital environment requires special attention to ensure a healthy indoor air quality (IAQ) to protect patients and healthcare workers against hospital-acquired infections and occupational diseases. Poor hospital IAQ may cause outbreaks of building-related illness such as headaches, fatigue, eye, and skin irritations, and other symptoms. The general objective for this study was to assess IAQ inside a large University hospital at Al-Khobar City in the Eastern Province of Saudi Arabia. Materials and Methods: Different locations representing areas where most activities and tasks are performed were selected as sampling points for air pollutants in the selected hospital. In addition, several factors were studied to determine those that were most likely to affect the IAQ levels. The temperature and relative percent humidity of different air pollutants were measured simultaneously at each location. Results: The outdoor levels of all air pollutant levels, except volatile organic compounds (VOCs), were higher than the indoor levels which meant that the IAQ inside healthcare facilities (HCFs) were greatly affected by outdoor sources, particularly traffic. The highest levels of total suspended particulates (TSPs) and those less than 10 microns (PM10) inside the selected hospital were found at locations that are characterized with m4ore human activity. Conclusions: Levels of particulate matter (both PM10 and TSP) were higher than the Air Quality Guidelines (AQGs). The highest concentrations of the fungal species recorded were Cladosporium and Penicillium. Education of occupants of HCF on IAQ is critical. They must be informed about the sources and effects of contaminants and the proper operation of the ventilation system. PMID:24696632

  11. California and Saudi Arabia: geologic contrasts

    SciTech Connect

    Alexander, R.G. Jr.

    1984-09-01

    Assessing hydrocarbon futures in unexplored basins involves geology by analogy. Through 1978, approximately 265 fields were discovered in California containing 22 billion bbl of oil, 53% being in the 10 largest fields, ranging in size from 0.6 to 2.4 billion bbl. Through 1978, about 50 fields were found in Saudi Arabia containing 206 billion bbl of oil, 78% in the 10 largest fields, ranging in size from 7 to 83 billion bbl. The contrasts in field size distribution and in the total amount of oil present are explained by the dramatically different geology and geologic histories. California's surface geology is characterized by rare Precambrian, isolated Paleozoic, and widespread Mesozoic accreted terranes and intrusions, and by highly uplifted and depressed Tertiary sedimentary prisms bounded by widespread high-angle thrusting and strike-slip and normal faulting. Numerous families of medium to small anticlines and fault traps, commonly involving moderately dipping to overturned beds, have resulted from Tertiary tectonism, which segmented California dramatically. Saudi Arabia is characterized by a broad Precambrian shield area, flanked on the east by very long, gently dipping cuestas of Paleozoic and Mesozoic sediments, with an upper thin veneer of nearly flat Tertiary strata. Most structures involving the Mesozoic and Cenozoic are large, but gentle and unfaulted, representing a passive reaction of the sediments to underlying mild basement distortion and/or movement of Cambrian salt, all occurring while the arabian plate continued to subside and tip to the northeast. The contrasts between California and Saudi Arabia oil field and geology result from contrasting plate-tectonic settings and history.

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

    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

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

    Objectives: Sleep deprivation is common among medical residents of all specialties. This study aimed to determine the prevalence of sleep deprivation and depressive symptoms among medical residents in King Fahd University Hospital (KFUH) in Al Khobar, Saudi Arabia. Furthermore, the association between sleep deprivation, sleepiness and depressive symptoms was examined. Methods: This cross-sectional study took place between February and April 2012 and involved 171 KFUH medical residents of different specialties. Data were collected using a specifically designed questionnaire eliciting demographic information, working hours and number of hours of sleep. In addition, validated Arabic versions of the Epworth Sleepiness Scale and the Beck Depression Inventory-2 (BDI-2) were used. Results: The prevalence of acute sleep deprivation and chronic sleep deprivation among residents in KFUH was 85.9% and 63.2%, respectively. The prevalence of overall sleepiness was 52%; 43.3% reported being excessively sleepy in certain situations while 8.8% reported being excessively sleepy regardless of the situation. Based on the BDI-2, the prevalence of mild, moderate and severe depressive symptoms was 43.3%, 15.2% and 4.7%, respectively. Significant associations were found between sleep deprivation and depressive symptoms; depressive symptoms and sleepiness, and depressive symptoms and being a female resident. Conclusion: The vast majority of medical residents had acute sleep deprivation, with more than half suffering from chronic sleep deprivation. The number of hours and quality of sleep among the residents were strongly associated with depressive symptoms. New regulations are recommended regarding the number of working hours and night duties for medical residents. Further studies should assess these new regulations on a regular basis. PMID:25685390

  16. The pharmacoeconomic picture in Saudi Arabia.

    2014-08-01

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

    2009-04-01

    This paper aims at presenting details of the application of assisted reproductive technology and the impact of the Islamic law (Sharia) on its practice in the Kingdom of Saudi Arabia (KSA). Analysis of the data sourced from manual searches of bibliographies from key articles showed that this technology in KSA is practiced in a strictly religious manner and certain aspects of the technology are completely forbidden. It further showed that lack of an official government in-vitro fertilization (IVF) registry to gather information on the activities of IVF clinics has limited the data available for international comparisons. Sharing information internationally could allow religiously concerned infertile couples to have access to the reproductive services in the Kingdom. It would further improve the quality of care, enhance certain techniques like in-vitro maturation and experimentation on embryos, by providing resources that are currently unavailable, keeping in view the religious beliefs and avoiding conflicts.

  3. The Najd Fault System of Saudi Arabia

    2014-05-01

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

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

  5. Essays on oil and business cycles in Saudi Arabia

    NASA Astrophysics Data System (ADS)

    Aba Alkhail, Bandar A.

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

    The biomedical research sector in Saudi Arabia has recently received special attention from the government, which is currently supporting research aimed at improving the understanding and treatment of common diseases afflicting Saudi Arabian society. To build capacity for research and training, a number of centres of excellence were established in different areas of the country. Among these, is the Centre of Excellence in Genomic Medicine Research (CEGMR) at King Abdulaziz University, Jeddah, with its internationally ranked and highly productive team performing translational research in the area of individualized medicine. Here, we present a panorama of the recent trends in different areas of biomedical research in Saudi Arabia drawing from our vision of where genomics will have maximal impact in the Kingdom of Saudi Arabia. We describe advances in a number of research areas including; congenital malformations, infertility, consanguinity and pre-implantation genetic diagnosis, cancer and genomic classifications in Saudi Arabia, epigenetic explanations of idiopathic disease, and pharmacogenomics and personalized medicine. We conclude that CEGMR will continue to play a pivotal role in advances in the field of genomics and research in this area is facing a number of challenges including generating high quality control data from Saudi population and policies for using these data need to comply with the international set up.

    Great numbers of circular, center-pivot irrigation plots appear in this west-looking view of northern Saudi Arabia (center to lower left). The entire country between the shifting sands of the Ad Dahna Sand Sea (light colors center and right) and the almost soilless Nejd Plateau (left) has been darkened by thousands of these agricultural fields. The Nejd Plateau is a mass of dark rocks, some volcanic, in northwest Saudi Arabia. The sweep of the Ad Dahna Sand Sea is one of the major features of Saudi Arabia (center and right) as seen from the orbiter. The dunes follow the trend of regional winds (northwesterly in the center of the view) which circulates around the Nejd plateau. The north end of the Red Sea can be seen top left with the Sinai Peninsula and Mediterranean are just visible center top. Iraq is under clouds top right.

    The respiratory care (RC) profession in Saudi Arabia is over 40-year-old. Although there have been major advancements in the profession, no history and enough information are available about its development and evolvement at current. This paper describes the history and development of the field of RC and future prospects for the profession in Saudi Arabia. A comprehensive review and assessment were conducted through direct contact, interviews, and a review of existing documents in the Medical Services Division of the Ministry of Defense, the Ministry of Health, The Ministry of Civil Services, representative hospitals, academic institutions, and other relevant texts. The data obtained were evaluated for its relevance and grouped on a thematic basis. This is currently the first paper about the history and development of the RC profession in Saudi Arabia over the last 45 years. PMID:27803748

    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.

    Background There is evidence that mapping mental health systems (MHSs) helps in planning and developing mental health care services for users, families, and other caregivers. 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.

    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.

    Context: Traumatic aortic injury (TAI) accounts for 1/3 of all trauma victims. Aim: We aimed to investigate the efficacy of the adopted standardized immediate pre-operative and intra-operative hemodynamic goal directed control, anesthetic technique and organs protection on the morbidity and mortality in patients presented with TAI. Settings and Design: An observational retrospective study at a single university teaching hospital. Materials and Methods: Following ethical approval, we recruited the data of 44 patients admitted to the King Fahd Hospital of the University, Al Khobar, Saudi Arabia, with formal confirmation of diagnosis of blunt TAI during a 5-year period from February 2008 to April 2013 from the hospital medical records. Statistical Analysis: descriptive analysis. Results: A total of 44 victims (41 men, median (range) age 29 (22-34) years) with TAI who underwent surgical repair were recruited. Median (range) post-operative chest tube output was 700 (200-1100) ml necessitated transfusion in 5 (11.4%) of cases. Post-operative complications included transient renal failure (13.6%), pneumonia (6.8%), acute lung injury/distress syndrome (20.5%), sepsis (4.5%), wound infection (47.7%) and air leak (6.8%). No patient developed end stage renal failure or spinal cord injury. Median intensive care unit stay was 6 (4-30) days and in-hospital mortality was 9.1%. Conclusion: We found that the implementation of a standardized early goal directed hemodynamic control for the peri-operative management of patients with TAI reduces the post-operative morbidity and mortality after surgical repair.

    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.

    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

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

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

    Health services occupy a high priority in the development agenda of Saudi Arabia, Saudi culture--devotion to Islam, extended-family values, the segregated status of females and the Al Saud monarchic hegemony--is being formulated in an increasingly deliberate fashion, constituting a new 'political culture' which acts as a screen to insure that technological and human progress remain within acceptable bounds. There is a general disposition on the part of the Saudi populace to use modern health services as these become available, largely under governmental auspice. The role of the government in providing health care for pilgrims during the hajj to Mecca is of particular culture importance. Cultural sensitivities concerning male physicians and female patients will be minimized by the training of a substantial number of Saudi female physicians, whose efforts will be directed toward female patients. At present, most health care in the Kingdom is delivered by male expatriate physicians, as part of the general massive reliance upon expatriate workers: although the expatriates will eventually be replaced by Saudi physicians, this dependency, which is felt to threaten Saudi culture, will continue for a decade or more. Private medicine is rapidly increasing though not on the same scale as government medicine. The provision of government health services is a source of legitimation for the Al Saud regime. In general, health services appear to constitute a form of modernization which meets the test of cultural compatibility.

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

    2013-01-01

    Background: Diabetes imposes a large economic burden on the individual, national healthcare systems, and countries. Objective: To determine the economic impact of diabetes mellitus on Saudi healthcare system, both now and in the future. Materials and Methods: This research study uses a prevalence-based approach that combines the demographics of the population (classified by nationality, sex and age group) with and without diagnosed diabetes in 1992 and 2010. 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 understanding of economic

    In the last decade, public health (PH) has come to the frontlines in Saudi Arabia. The recent outbreak of a novel corona virus (MERS-CoV) highlighted the importance of PH services and the need for a competent PH workforce. The urgency and panic induced by infectious disease outbreaks explain the heightened interest. Decision makers' interest in public health was observed through a series of decisions, including creating a position for Deputy Minister for Public Health, changing the name of "Directorate of Primary Healthcare Centers" to "Directorate of Public Health" in all health regions and initiating a special scholarship program to prepare health administration professionals in collaboration with US-based universities. A distinguished group of PH leaders in Saudi Arabia was gathered in a structured workshop that was organized by the Al Imam Mohammad Ibn Saud Islamic University, college of medicine to discuss the current status and future needs of PH education in the Kingdom of Saudi Arabia. The workshop highlighted the need for PH education development and outlined the challenges ahead. The main challenges laid out by participants in the workshop were the development of an appropriate PH curriculum, appropriate training spots for practical placement, the development of research priorities for PH to satisfy the needs of PH programs and agencies, attracting the most qualified academic staff, the enrolment of highly motivated students and finally, the establishment of a quality assurance program to ensure the quality of PH education programs. The development of a framework for graduate competencies in PH was perceived to be a top priority. Moreover, setting a PH workforce surveillance system, building partnership between PH academic institutions and PH services providers, implementing national campaigns to explain what PH is about and illuminating the role of PH workers were also of utmost importance.

    1975-07-19

    The maximum rise in blood glucose after 50 g lactose by mouth was determined in 40 adult Arabs. Out of 30 Bedouin, urban Saudi, and Yemeni and 9 of mixed ancestry (usually partly African), 25 (83%) and 2 (22%) respectively showed an increase of over 1-1 mmol/1 (20 mg/100 ml). In common with most northern Europeans and Hamitic people of northern Africa, Arabs in Saudi Arabia usually have high intestinal lactase concentrations in adult life. This persistence of high levels probably originated in the Arabian peninsula. Its selective advantage may have been associated with the fluid and calorie content of camels' milk, which is important for survival in desert nomads. PMID:1170003

    The kingdom of Saudi Arabia is currently witnessing a massive support for its healthcare services. This year's fiscal budget for health care is by far the largest in the history of the kingdom. While pursuing the conventional goals of healthcare delivery systems, such as equity, affordability and availability of services, the ministry of education (MOE), formerly called ministry of higher education (MOHE), is also seeking to achieve certain excellence standards, which are expected to set the bar for other countries in the region to follow suit. Almost all, under construction, university hospitals were adopting a paradigm shift in the standard of health care and training provided. This report summarizes these standards.

    Luminescence dating has been used to find the age of meteorite impact craters at Wabar (Al Hadida) in Saudi Arabia. The luminescence characteristics of the shocked material were determined. Using a variety of luminescence dating techniques applied to impactite formed by the meteorite, and to the underlying sand, the age is found to be 290 ± 38 years. A comparison is made with two possible historically recorded ages. An impact as young as this has implications for the assessment of hazards from the impact on Earth of small meteorites.

    Pediatric hand surgeons in Europe and North America are aware of the yearly "outbreak" of pediatric hand injuries on Halloween from carving pumpkins. This study reports another yearly "outbreak" of hand injuries--in Saudi Arabia from slaughtering sheep. During the 3 days of festivities following the Hajj ceremony, hundreds of thousands of sheep are slaughtered. Over 4 consecutive years, 298 patients attended the emergency room of Riyadh Central Hospital with injuries related to the slaughtering of animals sustained during the 3 days of festivity. Almost three quarters of patients (73%) were injured on the first day of festivity. The majority (92%) were nonprofessionals. Children accounted for 6.7% of patients. In adults, the female-to-male ratio was 1:7. The most common mechanism of injury was a knife cut (80.9%). Almost three quarters of injuries (73.5%) affected the hands, with more involvement of the left than the right hand. Only 7.7% of patients with hand injuries were admitted to the hospital for treatment. It was concluded that implementing safety measures while slaughtering, and educating the general population would be important in the prevention of these hand injuries in Saudi Arabia. PMID:10454321

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

    Programmes for early diagnosis of breast cancer are lacking in most countries in the Eastern Mediterranean Region. This paper reviews a nongovernmental screening programme launched in October 2009 in the Eastern Province of Saudi Arabia, in which 14 health centres were covered by 2 mobile mammography machines. Annual screening was offered to all women aged 40 years and above. Up to February 2014 a total of 8061 women were screened, an uptake rate of 15.0%. The recall rate was 7.9%. The number of cancers detected was 47, a cancer detection rate of 5.83 per 1000 women screened; 70.2% of the cancers detected had either no mass or the lesions were smaller than 2 cm. The mean age of women with cancer was 50.4 (SD 7.6) years. The screening parameters of our study correlated well with international standards. Despite the controversies regarding universal breast cancer screening, a national breast cancer screening programme for Saudi Arabia is needed. PMID:25876822

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

    A Prominent escarpment is found along the western margin of the Arabian Shield. Elevations along this escarpment are up to 3200 m above the Red Sea. Between the Red Sea and the crest of the escarpment is a relatively featureless coastal plane that is ??? 50 km across. The coastal plane abruptly gives way to the steep mountainous terrain, the elevation of which increases abruptly towards the high crest. The elevation slowly decreases to the east of the high crest. Forty-four apatite fission-track ages have been determined on rocks from the Proterozoic Arabian Shield in southwestern Saudi Arabia. These ages range from 13.8 to 568 Ma. In general, the youngest ages are found at low elevations along the base of the escarpment near the eastern edge of the coastal plane. The oldest ages are from along and to the east of the crest. The fission-track data from Saudi Arabia show that there was a period of minor uplift and cooling during the Cretaceous. This was followed by a relatively stable period which lasted until the Mid to Upper Miocene. The latest uplift and erosion began slightly younger than 13.8 Ma. This latest episode resulted in a minimum uplift of 3 km and is related to the Red Sea Rift. Samples totally annealed prior to this latest episode of uplift and cooling have not yet reached the surface.

    The objective of this study was to find out the prevalence, characteristics, and distribution of musculoskeletal pain among construction workers in Saudi Arabia. A questionnaire about musculoskeletal pain in different parts of the body was completed by 165 construction workers from the construction industries in Dammam and Riyadh cities. 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. PMID:25811043

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

    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.

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

    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.

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

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

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

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

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

    The medical records of 90 patients with a clinical diagnosis of retinal vein occlusion (RVO) who were seen at two referral hospitals in Saudi Arabia were reviewed. Sixty-eight (75.6%) were men. Central RVO was present in 50 patients (55.6%); branch RVO, in 35 patients (38.9%); and hemiretinal occlusion, in five patients (5.6%). Arterial hypertension was present in 43 patients (47.8%); diabetes mellitus, in 28 patients (31%); and preexisting glaucoma, in 26 patients (28.9%). The date of onset of RVO was available in 61 patients. Eighteen attacks (29.5%) had occurred during the month of Ramadan. The Student's t test of paired samples indicated that the incidence of RVO during the month of Ramadan was significantly higher than that of the other months of the Gregorian year. These findings suggest that dehydration may play a role in the pathogenesis of RVO. PMID:8304694

    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.

    1992-02-01

    In northwestern Saudi Arabia, an area of about 15 200 km is intermittently covered by basaltic rocks representing Cenozoic, intraplate continental volcanism. The present study is focused on the geochemical characteristics of these rocks, which are distinguished on the basis of field occurrences into three suites: 1. layered basalt (LB), 2. fragmented basalt (FB), and 3. cinder-cone material (CM), with varied ages. The rocks are olivine normative, belonging to the basanite-picrite-ankaramite series, with sodic and potassic varieties. A high degree of ferromagnesian fractionation and some compositional layering in the magma chamber are concluded. Crustal contamination indicated by some trace elements, progressively decreases with age, and hence, is interpreted as time dependent.

    Given the need for a uniform, comprehensive, electronic nationwide surveillance system for injuries in Saudi Arabia, a system was designed with the objectives of establishing an epidemiologic profile of injuries in the country; evaluating injury indicators on an ongoing basis; identifying high-risk groups requiring specific interventions; monitoring and evaluating interventions for effectiveness; and producing reports to assist in planning and resource allocation. A special form for this purpose was designed, modified from validated forms used elsewhere for injury surveillance. This initiative of the Ministry of Health is also expected to help validate data collected by other sectors, such as the Ministry of Interior. This paper reviews the milestones of building the system and aims to prompt a debate within the scientific community, especially within the Eastern Mediterranean Region, about the best way to design injury surveillance systems for the Region in order to fine-tune the proposed system before its full-scale implementation.

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

    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.

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

    Background. 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. PMID:27777590

    Panter-Brick, C

    1991-01-01

    In-depth interviews of 36 Saudi families whose children suffered from neuro-metabolic disorders were conducted at a specialist hospital in Riyadh in order to examine parental understanding of disease and attitudes towards future births and consanguineous marriages. Parents had difficulty accepting a genetic explanation for diseases that did not affect all children at the time of birth; they also expressed religious or folk beliefs to account for illness. Coping behaviours included denial and resignation to the situation, divorce and remarriage. Some families adopted a cautious approach to cousin marriages and future births; this was significantly related to their education level, but not to previous infant deaths. Awareness of medical facts brought little emotional comfort to parents but allowed for preventive measures through screening adult carriers and identifying affected infants. This study presents new material from Saudi Arabia to strengthen current awareness that the range of religious beliefs, social attitudes and reproductive behaviours adopted by families in a society undergoing rapid change is of direct relevance to health care.

    Candida dubliniensis is a newly described yeast species that is a close phylogenetic relative of C. albicans. Although it has been reported from different parts of the world, no detailed investigation of this species has been done in Saudi Arabia. The purpose of the present study was to identify C. dubliniensis isolates recovered from clinical specimens at a tertiary-care hospital in Riyadh, Saudi Arabia, and to determine the drug susceptibility profiles of those isolates. Over a period of 8 months, 823 germ tube- and chlamydospore-positive yeasts identified as C. albicans and recovered from different clinical specimens were screened for their ability to grow at 45°C on Sabouraud dextrose agar. Isolates which failed to grow at 45°C were presumptively identified as C. dubliniensis. The species identities were further confirmed by the production of pseudohyphae and chlamydospores on Staib agar and their inability to assimilate d-xylose and α-methyl-d-glucoside by using the API 20C AUX system. A total of 27 (3.3%) isolates were identified as C. dubliniensis. They were all recovered from 23 human immunodeficiency virus-negative patients. The prevalence of C. dublinensis in bronchoalveolar lavage (33.3%), oral (16.7%), and blood (16.7%) specimens was high. In addition, 33 isolates previously identified as C. albicans and preserved among our stock blood culture isolates were also recruited for the study. Of these, 5 isolates were found to be C. dubliniensis, thus making the total number of isolates identified as this species 32. Antifungal susceptibility testing of the C. dubliniensis isolates showed 100% sensitivity to amphotericin B, 97% sensitivity to each of fluconazole and ketoconazole, and 87.5% sensitivity to itraconazole. However, in contrast to other studies, the majority of the isolates (65.6%) showed high levels of resistance to flucytosine (MIC > 64 μg/ml). Further studies are warranted to investigate the cause of this unusually high rate of resistance to

    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.

    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.

    Mahd adh Dhahab is the largest of numerous ancient gold mines scattered through the Precambrian shield of Saudi Arabia and the only one with recent production. During the period 1939-54, 765,768 fine ounces of gold and 1,002,029 ounces of silver were produced from the mines by the Saudi Arabian Mining Syndicate. Ore minerals at Mahd adh Dhahab include free gold and silver, tellurides, sphalerite, and chalcopyrite in and associated with a system of north-trending quartz veins and quartz veinlet stockworks. Pyrite is a common sulfide gangue mineral. Country rocks are a north dipping sequence of pyroclastic and transported pyroclastic rocks of the Hulayfah Group that are locally highly silicified and potassium-feldspathized. The prime target for this exploration program was a north-trending zone of quartz veins and breccias, faults, alteration, and metalization approximately 400 m wide and 1000 m long. The ancient and recent mine workings are located in the northern part of this zone. Although the quartz veins and alteration cut all lithologies, the major metalization is confined to the intersection of veins and agglomerate. Ten holes were diamond drilled to explore geochemical, geological, and geophysical targets in the area. A significant new zone of metalization was discovered 700 m south of the ancient and recent mine workings and within the same major zone of quartz veins, alteration, and faults. Metalization in this southern mineralized zone is at the intersection of the quartz veins and a distinctive and highly altered agglomerate. The total zone of vein and agglomerate intercept is potentially metalized and comprises a block of ground 40 m thick and 400 m wide along the strike of the agglomerate and projected downdip 250 m. Tonnage of this block is 17.2 million tons. The explored zone, approximately 25 percent of the potentially metalized rock, has a potential resource of 1.1 million tons containing 27 g/t gold and 73 g/t silver.

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

    The end of the Cold War in the late 1980s resulted in a gigantic downsizing and consolidation of America`s defense industries, as domestic demand plummeted and the volume of international arms trading fell. However, in total world arms exports the United States exports more arms than any other nation. The country of Saudi Arabia has been the destination of a disproportionate amount of these weapons. The following account is an examination of the US military aerospace industry, the world military aerospace market, US government policy concerning arms exports, and the Saudi aerospace market. Each of these entities profoundly impacts US-Saudi military aerospace commerce. By individually analyzing the above factors, it will be demonstrated that the supply relationship between the US and Saudi Arabia is dependent on the convergence of several long standing and deep seated aspirations on the part of the three major players: the US Aerospace Industry, the US Government, and the Saudi Government. The US military aerospace industry`s exports are critical to ensure its independent survival, help fund crucial RD programs, and maintain a viable defense high tech industrial base in the U.S. In addition, it wishes to exert a military presence in the Gulf area and nurture relations with Saudi Arabia in particular, as the world`s leading oil producer. The Saudi government requires a military defense anchored in high tech aerospace systems, as well as a dependable and capable military ally such as the US.

    The objective of this study was to understand the usage patterns of dietary supplements among professional athletes in Saudi Arabia. The survey consisted of sixteen questions divided into four categories: use of supplements, reason for consumption of supplements, personal beliefs about supplements, and behavior. The questionnaires were given to the three teams residing in Riyadh: Al Hilal, Al Nasr, and Al-Shabab. Out of the 105 athletes surveyed, we found that only 98 are currently taking dietary supplements and the mean age and standard deviation were 25.74 ± 2.90. The survey results showed a high percentage of athletes (93.3%; n = 98) using different dietary supplements throughout the season, 43.8% (n = 43) reported using supplements for performance, and 32.6% (n = 32) believed in health benefits as a reason for using dietary supplements. Our results showed that a total of 87 (88.7%), 81 (82.6%), and 51 (52.0%) athletes are consuming sports drinks, vitamin C, and multivitamins, respectively. Meanwhile, those supplements ranking among the least used included omega 6 (18.6%), creatine (16.3%), and Ginkgo biloba (10.2%). A majority of athletes indicated that their use of supplements was for the purpose of improving their health and performance. PMID:23762541

    Measurements of radon exhalation for a total of 50 selected samples of construction materials used in Saudi Arabia were taken using a radon gas analyzer. These materials included sand, aggregate, cement, gypsum, hydrated lime, ceramics and granite. It was found that the granite samples were the main source of radon emanations. A total of 32 local and imported granite samples were tested. It was found that the radon exhalation rates per unit area from these granite samples varied from not detectable to 10.6 Bq m-2 h-1 with an average of 1.3 Bq m-2 h-1. The linear correlation coefficient between emanated radon and radium content was 0.92. The normalized radon exhalation rates from 2.0 cm thick granite samples varied from not detectable to 0.068 (Bq m-2 h-1)/(Bq kg-1) with an average of 0.030 (Bq m-2 h-1)/(Bq kg-1). The average radon emanation of the granite samples was found to be 21% of the total radium concentration. Therefore, granite can be a source of indoor radon as well as external gamma-radiation from the uranium decay series.

    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.

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

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

    Current hydrocarbon production in Saudi Arabia is from reservoirs of Cretaceous and Jurassic age. Geochemical studies of the sediments and oils suggest that the hydrocarbons were derived from two separate source-rock provinces. Oil production from the large fields in the southern part of the area is from Jurassic carbonate reservoirs. Most of these oils were derived from thermally mature, thinly laminated, organic-rich carbonate rocks of Jurassic age (Callovian-Oxfordian). These source rocks were deposited in an intrashelf basin which is limited to the southern part of the main producing areas. Extensive vertical migration of oils originating in these sediments is prevented by superjacent evaporite seals deposited during the Late Jurassic. Fields in the northern producing areas appear to have derived their hydrocarbons from a source-rock province on the north. Production from Cretaceous clastic and carbonate reservoirs is limited to the northeastern part of the producing areas. This distribution may be explained by limitation of thermally mature Cretaceous source rocks to the northeastern areas or by the local lack of subjacent evaporite seals to separate these reservoirs from Jurassic source rocks. Thermal maturation studies indicate that the hydrocarbons in Mesozoic reservoirs migrated into the present traps during the early Tertiary.

    Objectives: To identify the changing trends and crucial preventive approaches to road traffic accidents (RTAs) adopted in the Kingdom of Saudi Arabia (KSA) over the last 2.5 decades, and to analyze aspects previously overlooked. Methods: This systematic review was based on evidence of RTAs in KSA. All articles published during the last 25 years on road traffic accident in KSA were analyzed. This study was carried out from December 2013 to May 2014 in the Department of Family and Community Medicine, Taibah University, Al-Madinah Al-Munawwarah, KSA. Results: Road traffic accidents accounted for 83.4% of all trauma admissions in 1984-1989, and no such overall trend was studied thereafter. The most frequently injured body regions as reported in the latest studies were head and neck, followed by upper and lower extremities, which was found to be opposite to that of the studies reported earlier. Hospital data showed an 8% non-significant increase in road accident mortalities in contrast to police records of a 27% significant reduction during the years 2005-2010. Excessive speeding was the most common cause reported in all recent and past studies. Conclusion: Disparity was common in the type of reporting of RTAs, outcome measures, and possible causes over a period of 2.5 decade. All research exclusively looked into the drivers’ faults. A sentinel surveillance of road crashes should be kept in place in the secondary and tertiary care hospitals for all regions of KSA. PMID:25828277

    Contamination of groundwater by nitrate is considered a global problem. Nitrates are introduced in the groundwater from a variety of sources like agricultural activities, poor sewer system, wastewaters, and industrial activities. In the present research, a survey of wells (n = 1,060) was undertaken in all 13 regions of the Kingdom of Saudi Arabia to assess the contained nitrate (NO(3)) levels. The results indicated variation in nitrate levels from 1.1 to 884.0 mg/L as NO(3) throughout the Kingdom. The average nitrate levels in milligrams per liter as NO(3) were as follows in descending order: 65.7 (Jizan), 60.3 (Asir), 60.0 (Qassim), 51.3 (Hail), 41.8 (Makkah Al Mukaramma), 41.3 (Madina Al Munnawara), 38.0 (Al Baha), 37.0 (Najran), 30.7, (Tabouk), 25.2 (Eastern Province), 18.8 (Riyadh), 15.8 (Al Jouf), and 9.1 (Hadwed Shamalyah). The results indicated that nitrate levels exceeded the maximum contaminant limits for drinking water (45 mg/L as NO(3)) in a number of wells (n = 213) in different regions of the Kingdom. The maximum and minimum wells exceeding the maximum contaminant limits for nitrate in drinking water were in Jizan (52.6%) and Hadwed Shamalyah (4.9%), respectively. Most of the wells which exceeded the maximum allowed limits for nitrate were in the areas which were used for agricultural and residential purposes.

    Air pollution exposure has been shown to be associated with an increased risk of specific cancers. This study investigated whether the number and incidence of the most common cancers in Saudi Arabia were associated with urban air pollution exposure, specifically NO2. Overall, high model goodness of fit (GOF) was observed in the Eastern, Riyadh and Makkah regions. The significant coefficients of determination (r2) were higher at the regional level (r2 = 0.32–0.71), weaker at the governorate level (r2 = 0.03–0.43), and declined slightly at the city level (r2 = 0.17–0.33), suggesting that an increased aggregated spatial level increased the explained variability and the model GOF. However, the low GOF at the lowest spatial level suggests that additional variation remains unexplained. At different spatial levels, associations between NO2 concentration and the most common cancers were marginally improved in geographically weighted regression (GWR) analysis, which explained both global and local heterogeneity and variations in cancer incidence. High coefficients of determination were observed between NO2 concentration and lung and breast cancer incidences, followed by prostate, bladder, cervical and ovarian cancers, confirming results from other studies. These results could be improved using individual explanatory variables such as environmental, demographic, behavioral, socio-economic, and genetic risk factors. PMID:24192792

    Doctor-patient communication is a skill essential for the satisfaction of the patients’ needs and expectations. It involves an art that every practicing physician should have. The situations in health care delivery that demands good doctor-patient communication are many. Diabetes care, the management of hypertension, explaining serious disease diagnoses, prognosis, and investigative procedures are some of the common situations where good doctor-patient communication is very essential. Doctor-patient communication assumes a special status in Saudi Arabia where as a result of mixed ethnicity of the manpower in the health service and the expatriate community, there is a vast diversity of languages, health traditions and beliefs. The skill of doctor-patient communication can be developed and improved by the application of the principles of the patient-centered approach, the utilization of patient-oriented evidence that matters, and its inclusion in the undergraduate curriculum in the first few years of medical school. There should be continuous medical education programs for practicing doctors on the skills of doctor-patient communication through seminars and workshops. This would be a further step towards the improvement of the consumer's well-being. PMID:23008663

    Samples were collected from 1025 wells supplying drinking water to the 13 regions of Saudi Arabia and analyzed for radon concentrations. The weighted radon median value for the entire country was found to be 4.62 Bq L(-1) with a range of 0.01-67.4 Bq L(-1). The percentage of samples with radon concentration equal to or greater than 11.1 Bq L(-1) (US EPA proposed MCL) was found to be 19.22%. The range of radon in shallow wells varied between 0.06 and 67.4 Bq L(-1) (median value 5.1 Bq L(-1)) and between 0.06 and 40.9 Bq L(-1) (median value 5.34 Bq L(-1)) for deep wells. However, 50% of the samples had radon concentrations equal to or greater than 4.0 and 2.87 Bq L(-1) for the shallow and deep wells, respectively. Correlation of well depth with radon levels revealed that wells drilled in Saq aquifer consisting of predominantly sandstone with significant shale layers in the upper parts, gave higher median radon levels than in Manjur aquifer which consists of predominantly limestone and sandstone.

The low population (6 million) compared to the large area of the country (2,253,300 kmS, 900,000 miS) coupled with the high cost of crushed aggregate makes maintenance and road building costs very high. Local emulsified-asphalt economics, plants, and uses were investigated in this study. Emulsified asphalt proved to be attractive when used for local road maintenance and road bases and low-volume road construction, especially when used with dune sand and marl. Emulsified asphalts were evaluated for use with dune sand and marl and at two portland cement contents. Three types of emulsified asphalts were used which included locally produced, laboratory prepared, and Chevron USA emulsions. Emulsion treated mixes were tested for tensile strength, Poisson's ratio, resilient modulus, fatigue life, and rutting characteristics. Both diametral and beam fatigue tests were used and tests were conducted at 10, 25, 40, and 55C (50, 77, 104, and 131F). The open-graded mix was tested for fatigue characteristics using beam flexure with a confining membrane.

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

    Objective. To study life styles and dietary behaviors among Saudi preschool children (1–5 years) attending primary health care centers (PHCCs) in Dammam and Qatif areas, eastern province, Saudi Arabia. Material and Methods. Cross-sectional study. Data were collected using structured, interviewer-filled questionnaire. Children and their mothers were encountered during their well-baby clinic visits. A total number of 300 preschool children and their mothers were interviewed during study period. Results. Unsatisfactory areas include smoking fathers (32%), smoking in front of children (11.3%), overweight and obesity among mothers (60.3%), noncompliance using seat belts for both parents (56.3%) and children (68%), children watching television (T.V) more than 2 hours (50%), adherence to exclusive breast feeding (only 20.7%), and late solid food introduction (65.3%). Frequent intake of unhealthy food items was 26%, 25%, and 24% for pizza, burger, and soft drinks. Unfortunately frequent intake of the following unhealthy food items was high: biscuits, deserts/chocolates, and chips which was 78%, 67%, and 72%, respectively. Conclusion. This study provides benchmark about the current situation. It provides health care workers and decision makers with important information that may help to improve health services. PMID:25114804

    The AlKhobar City affected by distant earthquakes from Zagros fold-fault belt of subduction zone. These earthquakes produced great site effects on the sedimentary layers that in turn significantly influenced earthquake ground motions in the area. Mapping of site response using microtremor measurements compared with geological and borehole data of Alkhobar city is the main target of this work. The resonance frequency and their H/V values have been calculated using Nakamura technique through deployed of seismograph instruments at 113 sites in AlKhobar city for different time periods. The recording length was about one hour with sampling frequency of 100 Hz. Most of the measured sites present three peaks for the resonance frequency; the first peak ranges from 0.33 to 1.03 Hz, the second peak ranges from 1.03 to 1.23 Hz, while the third peak ranges from 1.23-1.73. Tests have been conducted to ensure that these peaks are natural in origin. The northern zones of AlKhobar City have lower values of resonance frequency indicating great thickness of sediments. In contrast, the southern parts of the city have higher values of resonance frequency illustrating shallow depths of the bedrock. Furthermore, twenty of boreholes have been conducted through AlKhobar City to different depth. Standard penetration test (SPT) data has been corrected and used to calculate the resonance frequency at their locations. Borehole results clarified that the resonance frequency values range from 0.27 to 1.95 Hz. These results are correlated well with that of the microtremor measurements. Accordingly, the first peak have been interpreted due to the impedance contrast between the limestone and the overlying sediments, while the third peak is originated from a boundary between the upper most surface layer and the underlying sediments. These results must be applied for earthquake risk mitigation in AlKhobar City.

    An extra-pulmonary tuberculosis (EPTB) infection rate of 30% in Saudi Arabia remains above the global rate. A variable rate of infection in each province has been reported and the involvement of most organs has been cited. Nationwide collective data on the current trends of infection are scarce and the factors behind the increased rate of EPTB are perplexing. This review endeavors to shed light into the epidemiology of EPTB, various types of infections sites, geographical differences in the infection rate, known risk factors, and challenges in the diagnosis and management of EPTB in Saudi Arabia.

    Global nursing shortages have necessitated closer scrutiny of recruitment and retention initiatives of nurses both locally and internationally. For many decades the nursing workforce of Saudi Arabia has relied on international expatriates to be the backbone of the industry. In recent years however, Saudi women have been recruited into nursing preparation courses conducted at degree level. The many twists and turns of providing a local Saudi Arabian nursing workforce has paralleled Saudi's own history and this paper follows that journey. Our research has enabled us to provide some insights into nursing pre and post the enlightenment that accompanied the Prophet Mohammed's influence. We emphasize the influences of women leaders who emerged in Mohammed's time and bring lasting authority to the development of nursing in Saudi Arabia. The cultural issues that bind women in this society are explicated and related to recruitment and retention issues in nursing. Education matters, both past and present, are highlighted emphasizing the gains that nursing as a distinct occupation has made. Finally the paper concludes with a summation of contemporary achievements in Saudi Arabia moving nursing towards the much needed professional status and parity with other careers in health care.

    Significant reserves of Arabian super light oil, condensate, and associated gas occur in the various genetically different sandstone bodies of the upper Permian Unayzah and Khuff Formations in Central Saudi Arabia. The Unayzah Formation which rests unconformably on the older formations is composed of red colored, poorly sorted conglomerate, sandstone, siltstone, mudstone, caliche and nodular anhydrite. Facies changes occur due to the presence of various subenvironments and possible faulting and structural growth in the basin during deposition. However, the entire Unayzah Formation shows an overall fining and thinning-upward sequence. It was deposited as coalescing alluvial fans dominated by braided streams which graded into meandering stream and playa lakes under and to semi-arid conditions. Eolian processes were also inferred. A marked unconformity which is indicated by the occurrence of thick caliche and soil horizons separate the Unayzah and the overlying Khuff Formation. The Khuff Formation consists primarily of marine shale, marl, and fine- to very coarse-grained sandstones in the lower parts; shale, limestone, dolomite, and amhydrite in the upper parts. The sandstones were deposited as incised channel fills and their associated low stand deltaic sediments as a result of fluctuating sea level during the deposition of the Khuff Formation. The base of the incised channels represent a sequence boundary. Red colored and rooted paleosols were formed on the underlying marine sediments. During relative sea level rise, good quality reservoir sands were deposited by aggradation within the incised channels. Sand deposition within the channels terminated at the same time, and the area was covered by shallow marine limestones, shales and marls during maximum sea level highstand. Although the Unayzah reservoir occurs in both the Unayzah and the Khuff Formations because of their different geometry, continuity, and reservoir quality, they have been studied separately.

  14. Harmonic analysis of precipitation climatology in Saudi Arabia

    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.

    Saudi Arabia is undergoing a rapid population growth that along with improved socioeconomics has led many individuals to own a car or even a number of cars per family, resulting in a greater number of vehicles on the roads. The reduced focus on good public transportation systems and the dependence on cars for transportation have created a diversity of drivers who are unfamiliar with the local driving rules and lack the basic skills for safe driving. This is in addition to some young drivers who frequently violate traffic laws and tend to speed most of the time. This unplanned expansion in road traffic has resulted in more car accidents, injuries, disabilities, and deaths. Accompanying that is an increased socioeconomic burden, depletion of human resources, emotional and psychological stress on families, and a strain on healthcare facilities. If this continues without prompt intervention, it will lead to increased insurance premiums and may become unmanageable. To minimize this impact, a national or regional multidisciplinary trauma system has to be developed and implemented. A trauma system is a preplanned, comprehensive, and coordinated regional injury response network that includes all facilities with the capability to care for the injured. Essential components of the system include trauma prevention, prehospital care, hospital care, rehabilitation, system administration, trauma care education and training, trauma care evaluation and quality improvement, along with the participation of society. Research has documented a significant decrease in morbidity and mortality from trauma after the implementation of such systems, depending on their efficiency. The purpose of this review is to discuss the problem of road traffic accidents in this country and address the trauma care system as an effective solution. PMID:20103958

    We have investigated the Ash Shutbah circular structure in central Saudi Arabia (21°37'N 45°39'E) using satellite imagery, field mapping, thin-section petrography, and X-ray diffraction of collected samples. The approximately 2.1 km sized structure located in flat-lying Jurassic Tuwaiq Mountain Limestone has been nearly peneplained by erosional processes. Satellite and structural data show a central area consisting of Dhruma Formation sandstones with steep bedding and tight folds plunging radially outward. Open folding occurs in displaced, younger Tuwaiq Mountain Limestone Formation blocks surrounding the central area, but is absent outside the circular structure. An approximately 60 cm thick, unique folded and disrupted orthoquartzitic sandstone marker bed occurring in the central area of the structure is found 140 m deeper in undisturbed escarpment outcrops located a few hundred meters west of the structure. With exception of a possible concave shatter cone found in the orthoquartzite of the central area, other diagnostic shock features are lacking. Some quartz-rich sandstones from the central area show pervasive fracturing of quartz grains with common concussion fractures. This deformation was followed by an event of quartz dissolution and calcite precipitation consistent with local sea- or groundwater heating. The combination of central stratigraphic uplift of 140 m, concussion features in discolored sandstone, outward-dipping concentric folds in the central area, deformation restricted to the rocks of the ring structure, a complex circular structure of 2.1 km diameter that appears broadly consistent with what one would expect from an impact structure in sedimentary targets, and a possible shatter cone all point to an impact origin of the Ash Shutbah structure. In fact, the Ash Shutbah structure appears to be a textbook example of an eroded, complex impact crater located in flat-lying sedimentary rocks, where the undisturbed stratigraphic section can be

    Here we present the first proof of an impact origin for the Saqqar circular structure in northwestern Saudi Arabia (Neville et al. ), with an apparent diameter of 34 km, centered at 29°35'N, 38°42'E. The structure is formed in Cambrian-Devonian siliciclastics and is unconformably overlain by undeformed Cretaceous and Paleogene sediments. The age of impact is not well constrained and lies somewhere between 410 and 70 Ma. The subsurface structure is constrained by 2-D reflection seismic profiles and six drilled wells. First-order structural features are a central uplift that rises approximately 2 km above regional datums, surrounded by a ring syncline. The crater rim is defined by circumferential normal faults. The central uplift and ring syncline correspond to a Bouguer gravity high and an annular ring-like low, respectively. The wells were drilled within the central uplift, the deepest among them exceed 2 km depth. Sandstone core samples from these wells show abundant indicators of a shock metamorphic overprint. Planar deformation features (PDFs) were measured with orientations along (0001), {101¯3}, and less frequently along {101¯1} and {101¯4}. Planar fractures (PFs) predominantly occur along (0001) and {101¯1}, and are locally associated with feather features (FFs). In addition, some shocked feldspar grains and strongly deformed mica flakes were found. The recorded shock pressure ranges between 5 and 15 GPa. The preserved level of shock and the absence of an allochthonous crater fill suggest that Saqqar was eroded by 1-2 km between the Devonian and Maastrichtian. The documentation of unequivocal shock features proves the formation of the Saqqar structure by a hypervelocity impact event.

    Objective: The study was conducted to assess the postural awareness of dental students in Jizan, Saudi Arabia. Materials and Methods: Close-ended, self-administered questionnaires were used for data collection in the survey. The questionnaire was prepared by observing the positions of students working in the clinics and the common mistakes they make with regard to their postures. The questionnaires were distributed among the dental students who were present and reported to work in the clinics. Levels of postural awareness and the relationship between postural awareness and the degree of musculoskeletal disorder (MSD) among the students was evaluated. This study was carried out in the College of Dental Sciences and Hospital, Jizan. Statistical Analysis: The level of knowledge of postural awareness was evaluated and correlated with the presence or absence of the MSDs. Categorical variables were compared using Chi-square test. P values of less than 0.05 were considered statistically significant. Results: A total of 162 dental students from the age group of 20–25 years were included in the survey, of which 134 dentists responded (83%). When their postural awareness was evaluated, results showed that 89% of the students had poor-to-medium levels of postural awareness. The relation between postural awareness and prevalence of MSDs indicated that 75% of the students with poor awareness, 49% of the students with average awareness, and 40% of the students with good awareness have MSDs. The results were statistically significant (0.002127, which is <0.005) stating that better awareness about proper postures while working helps to minimize the risk of MSDs. Conclusion: Evaluation of levels of postural awareness showed that 21% of the students had poor postural awareness, 67% had average awareness, and 11% had good postural awareness. The analysis of results showed that those students with low-to-average postural awareness had significantly greater prevalence of MSDs. PMID

    Background Dermatophytes are a scientific label for a group of three genera (Microsporum, Epidermophyton and Trichophyton) of fungus that causes skin disease in animals and humans. Conventional methods for identification of these fungi are rapid and simple but are not accurate comparing to molecular methods. Objective This study aimed to isolate human pathogenic dermatophytes which cause dermatophytosis in Riyadh City, Saudi Arabia and to identify these fungi by using conventional and molecular methods. Methods The study was conducted in Medical Complex, Riyadh and King Saud University. Samples of infected skin, hairs and nails were collected from 112 patients. Diagnosis of skin infections, direct microscopic test, isolation and identification of dermatophytes by conventional and molecular methods were carried out. Results The results indicated that the tinea capitis infection had the highest prevalence among the patients (22.3%) while Tinea barbae had the lowest. In this study the identified dermatophyte isolates belong to nine species as Trichophyton violaceum, Trichophyton verrucosum, Trichophyton rubrum, Trichophyton mentagrophytes, Trichophyton schoenleinii, Trichophyton concentricum, Microsporum canis, Microsporum audouinii and Epidermophyton floccosum which cause skin infections were isolated during this study. Non dermatophyte isolates included 5 isolates from Aspergillus spp. 4 isolates from Acremonium potronii and 15 isolates from Candida spp. M. canis were the most common species (25% of isolated dermatophytes). Out of the 52 dermatophyte isolates identified by conventional methods, there were 45 isolates identified by the molecular method. Conclusions The results concluded that approximately M. canis caused a quarter of dermatophyte cases, tinea capitis infection was prevalent and the molecular method was more accurate than conventional methods.

    Objectives Severe sepsis is a major public health concern and a frequent cause of intensive care unit (ICU) admission with a high fatality rate. Higher (Sequential Organ Failure Assessment score) SOFA score and co-morbidity of acute renal failure (ARF) are risk factors contributing to fatal outcome. This work was meant to study the epidemiology of sepsis in Buraidah central hospital. Methods This is a descriptive study conducted in the period from January 1, 2012, to June 29, 2012 to determine the epidemiology (incidence, clinical characteristics) and the outcome of sepsis in Buraidah hospital, Saudi Arabia. Results Out of 387 patients admitted to ICU, 62 (16%) patients had sepsis, their mean (SD) age was 62.7 (21.3) years. Three quarters of them 47 (75.8%) presented with septic shock. The median APACHE II score was 26.5 (8 to 48) and SOFA score 11 (5 to 21). The mean of duration of hospital stay was 11.95 days. The most frequent infection site was the pulmonary (69.5%). There were 37 isolated organism, gram-negative organisms (13; 35.13%) were the predominant isolates. There were 25 (40.3%) deaths; the majority of the deaths were due to septic shock 20(80%). There was a significant difference between deaths and the survivors, in the APACHI II score, SOFA score), and whether ventilated or not. Conclusions There was a high incidence of septic shock (and higher mortality) among the patients admitted to the ICU of Buraidah central hospital, especially among the elderly patients with respiratory infections.

    Objectives: To investigate perceptions and expectations of patients regarding hospital outpatient services by using a service quality gap model and factors influencing such gaps. Methods: In this cross-sectional descriptive study conducted between October and November 2014 in the outpatient waiting areas of a hospital in the Eastern Province of Saudi Arabia, a sample of 306 patients was selected by convenience sampling technique. The data was collected through an Arabic version of the service quality (SERVQUAL) questionnaire consisting of 2 parts: patients’ demographic characteristics, and 22 items scales of patients’ expectations and perceptions of SERVQUAL. The data was analyzed by confirmatory factor analysis, independent, and paired t samples tests and one way analysis of variance test. Results: The results showed that the proposed model for service quality dimensions had a good fit by satisfying the recommended values. The patients’ expectations exceeded perceptions in all service quality dimensions indicating statistically significant service quality gaps (t=26.3, p<0.000). Findings revealed that the empathy dimension contributed most patients’ expectations (4.7 ± 0.5) and perceptions (3.7 ± 0.8) scores, and responsiveness contributed least to expectations (4.5 ± 0.6) and perceptions (3.2 ± 0.8) scores. Prompt services showed highest service quality gap, while observation of privacy showed the smallest service quality gap in the statements. The study showed a significant association between gender, age, education, multiple visits, and service quality dimensions. Conclusion: The proposed model is valid and reliable and significant service quality gaps of all 5 dimensions need to be prioritized and addressed by focused improvement efforts of hospital management.

    2009-12-01

    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

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

    2016-02-01

    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).

    2015-01-01

    Objectives: To examine perceived stress among residents in Saudi Arabia and its associated risk factors. Methods: A cross-sectional study of all residents registered at the Saudi Commission for Health Specialties, Riyadh, Saudi Arabia, was conducted between May and October 2012. We assessed the likelihood of stress using the perceived stress scale (PSS). Results: Out of the 4000 residents contacted, 1035 responded and 938 were included. The mean (±standard deviation) PSS score was 22.0±5.1 (median 22 and inter-quartile range of 18-25). With the exception of gender and nationality, no significant associations were found between stress and socio-demographic or behavioral factors. Stress was associated with higher workload, sleep deprivation, dissatisfaction with colleagues and the program, and harmful ideations. Stressors included work-related, academic, and homesickness stressors. In multivariate analysis, the following were independently associated with stress: Saudi nationality, facing homesick stressor, facing work-related stressor, dissatisfaction with relationships with colleagues, and frequent thoughts of quitting the medical profession. Conclusion: Residents in Saudi Arabia are at comparable or slightly higher risk of perceived stress than that reported among residents worldwide. Unfortunately, most of the participants never received stress management, which highlights the need for stress management programs during residency. PMID:25935183

    2016-01-01

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

    2015-03-01

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

    2016-01-01

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

    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.

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

    Al-Otaibi, Nasir K.

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

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

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

    BACKGROUND The rise in childhood eye diseases has become a matter of concern in Saudi Arabia, and hence a study has been conducted on the residents of Jazan. The aim of the research was to find out the root cause of such issues and provide a solution to prevent such circumstances for it may affect the vision of children. In this study, therefore, we aimed to determine the types of childhood eye diseases in Jazan and to discuss the best ways to prevent them or prevent their effect on the vision of our children. Our institutions are working toward the longevity and welfare of the residents, and healthcare is one of the important aspects in such a field. METHODS This is a retrospective review of all patients less than 18 years of age who presented to the pediatric ophthalmology clinic of Prince Mohammed Bin Nasser Hospital, Jazan, between October 2014 and October 2015. The data, collected on 385 cases, included the age at first presentation, sex, clinical diagnosis, refractive error (RE) if present, and whether the child had amblyopia. If the child did not undergo complete ophthalmic examination with cycloplegic refraction, he/she was excluded. All data were collected and analyzed using the software SPSS. A P-value < 0.05 was considered statistically significant. RESULTS We reviewed the files of 385 children, with a male/female ratio of 1.1:1.0. The group aged 0–6 years made up the largest group (P = 0.01), and the ratio is an expression to define the credibility of the study using a chi-squared test. Strabismus (36.9%), RE (26.5%), ocular trauma (7.5%), infection of cornea and conjunctiva (7.3%), and keratoconus (6.2%) were the most common conditions. There was no significant difference in presentation by age group and sex among children with REs and squint. Trauma was seen more commonly among males and in the group aged 12–18 years.

  17. Chemostratigraphy of the Silurian Qusaiba Member, Eastern Saudi Arabia

    2016-01-01

    Given the unavailability of high resolution biostratigraphic data and difficulties in using lithostratigraphy for stratigraphic correlation, it was decided to employ chemostratigraphy to propose a scheme for the Silurian Qusaiba Member encountered in five wells in Eastern Saudi Arabia. Chemostratigraphy may be defined as a reservoir correlation technique involving the utilization of inorganic geochemical data. Although Inductively Coupled Plasma - Optical Emission Spectrometry (ICP-OES) and Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) were used to acquire data for 50 elements, the scheme is based on changes in the following 'key' element ratios: Zr/Th, Cr/Ti, Th/Nb, Zr/P, Y/Yb, Zr/Yb and Y/P. Variations in these parameters are largely dependent on changes in source/provenance, reflecting increases or decreases in the abundances of particular detrital heavy minerals. The scheme comprises a hierarchical order of four zones, seven subzones and four divisions. The zones are labelled C1, C2, C3 and C4 is ascending stratigraphic order, with two, three and two subzones identified in C2, C3 and C4 respectively. In addition to this, chemostratigraphic divisions are noted in two of the subzones. The chemostratigraphic scheme is considered robust as chemozones (general term used to describe any zone, subzone or division) are clearly defined in each well using geochemical profiles and binary diagrams plotted for key element ratios. Furthermore, high levels of statistical confidence are associated with the chemozones and most are correlative between three or more wells. The nonexistence of chemozones in particular wells is mainly explained by the sampling strategy employed. For example, the absence of subzone C3-2 (occurring towards the center of zone C3) in wells 4 and 5 is most likely to be explained by the uppermost part of the Qusaiba Member not being sampled. In other instances, particular chemozones may be missing as a result of erosion/non-deposition on a

    In Saudi Arabia, coastal sabkhas cover extensive areas along the coasts of the Red Sea and Arabian Gulf in addition to the continental sabkhas scattered in many places inland. Al-Lith sabkha is one of the typical coastal sabkhas located along the Red Sea coast. Sabkhas, in general, pose a number of geotechnical problems and need to be carefully investigated before being urbanized. A generalized geologic section in Al-Lith sabkha indicates a salty crust at the surface followed by yellowish brown silt and silty sand, olive gray silt and sandy silt and bottomed by coralline reefal limestone. Within this succession, there are several isolated lenticular bodies of sandy silt, silty sand and shelly silty sand. The clay minerals constituting the fine-grained portion of the soil are, in decreasing order, kaolinite, illite and montmorillonite in addition to minor chlorite. The depth to groundwater in 17 observation wells ranged from 0.18 to 1.81 m with a maximum fluctuation of 0.60 m between summer and winter. The permeability of the top silt layer was found to be very low with an average of 5.4×10 -4 m/day. A pumping test was performed in a deep well penetrating the coralline limestone. The measured permeability is 1.1×10 2 m/day and the estimated storage coefficient is 4×10 -5. Soil water evaporation was measured using a lysimeter constructed with undisturbed soil samples having different depths to the water level. The rate of evaporation ranges from 2.8 to 27.8 ml/day decreasing with an increase in depth to the water level. Groundwater samples were analyzed for their major anions and cations. Salt concentrations show a general increase toward the sea except for the calcium and carbonates that show a landward increase. The groundwater could be classified as a Cl+SO 4 brine. The salinity of the groundwater was determined at different depths in the pumping well and was found to be low in the top 4 m. It sharply increases until it reaches a value approximately 10 times

    Saudi Arabia is the largest country of the Arabian Peninsula, blessed with significant natural resources, including oil, gas and minerals. Saudi Arabia has recognised the importance of education in social and economic transformation, and has established a large number of universities, research and advanced technical institutes which have broken the metropolitan boundaries and have been extended to the far-flung areas of the country. There are 68 universities and degree-awarding institutes. The educational budget reached its highest-ever level of $56.56 billion for the year 2014. About 124,000 Saudi students are pursuing higher education in about 500 universities around the world. Saudi Arabia produced 177826 research papers in Institute for Scientific Information (ISI) database and in the year 2014 alone, 26168 research papers were published in indexed science journals with a rising h-index of 144. The country is turning into a regional hub for advanced education, research, science and technology while swiftly shifting from an oil-based to a knowledge-based economy.

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

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

    Background PHC Patient’ satisfaction represents a key marker for the quality of health care delivery and this internationally accepted factor needs to be studied repeatedly for smooth functioning of the health care systems. The objectives of the current study were to determine the level of patients’ satisfaction with the primary health care services provided in Majmaah city, Kingdom of Saudi Arabia; to identify the reasons behind satisfaction or dissatisfaction and to determine the effect of the social factors on the level of satisfaction. Methodology The study was a cross-sectional facility- based. The sample comprised 370 patients selected by stratified and systematic sampling at the health centers’ level and the patients’ level respectively. The data were collected by a pre-tested questionnaire and analyzed by SPSS software. Results Patients’ level of satisfaction was 82%. The reasons behind satisfaction were cleanliness of the facilities and technical competencies of the staff (33.1% and 24.2%). The study showed that the most stated reason behind dissatisfaction was the unsuitable buildings (29%). Significant association was found between the level of patients’ satisfaction about PHC centers services and the respondents’ level of education. Conclusion The level of satisfaction with the services provided by PHC centers in Majmaah is high. The gender, marital status and income have no effect on the level of satisfaction with the services provided by PHC centers. However, the lower educated are more satisfied than the higher educated. Cleanliness, competence of the staff along with respect and good handling are the drivers behind the high level of satisfaction. PMID:26309435

    "Women constitute the key resource for attaining the goal of health for all by the year 2000," maintains a report by The World Health Organization. Achieving this goal requires massive efforts including (1) the training of women health care professionals; and (2) the nonformal health education of women, the primary health care providers to their families and communities. This paper focuses on the first area, specifically on the education of women nurses in a Third World country, Saudi Arabia, where traditional attitudes persist against intermingling of the genders and the treatment of women by men. It examines the progress and problems encountered in recruiting Saudi women for nursing education and practice; describes the evolution of nursing education programs; and analyzes the obstacles to women's participation in these programs and in the nursing profession. The paper concludes with recommendations to address the problem, increase women's participation, and contribute to that country's health development. The paper is based upon primary and secondary data, including official statistics; personal interviews with Saudi women health professionals and students; the memoirs of a leading Saudi woman nurse and educator, the author's personal observations and experiences with the health care system during four years of residence in Saudi Arabia, and available literature on the subject.

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

    Currently, dengue fever is considered as the main health problem in several parts (Mekkah, Jeddah, Jazan and Najran) of Kingdom of Saudi Arabia (KSA) with dramatically increase in the number of cases reported every year. This is associated with obvious ineffectiveness in the recent control and management programs for the mosquito vector (Aedes aegypti). Here, we suggested promoting the health education and public awareness among Saudi people to improve the control of dengue mosquito vector. Several suggestions and recommendations were highlighted here to ensure effectiveness in the future control and management programs of dengue mosquito vector in KSA.

    The Jabal Riah area is in the southern part of the Jibal al Hamdah quadrangle (lat 19?00'00'' to 19?07'S0'' N., long 45?37'30'' to 43?45'00' E.) in the southeastern Precambrian Shield, Asir Province, Kingdom of Saudi Arabia. The Jabal Mahanid group of ancient gold mines, which is part of the Jabal Ishmas-Wadi Tathlith gold belt, is in the west-central part of the area. Rocks in the Jabal Riah area consist of Precambrian layered metasedimentary and metavolcanic rocks intruded by Precambrian igneous rocks. The metamorphic rocks are, from oldest to youngest, interlayered hornblende and biotite schist, quartz-biotite schist, hornblende schist, serpentinite, and chlorite schist. The igneous rocks are, from oldest to youngest, diorite-gabbro including dikes, granodiorite, monzogranite-granodiorite, leucocratic quartz porphyry, rhyolite, and aplite and pegmatite dikes. A large area of jasper replaces serpentinite. On the valley floors, recent alluvium and pediment deposits overlie the bedrock. The structure of the area is dominated by a dome centered over the eastern border of the area; leucocratic quartz porphyry forms the core of the dome. Minor folds and faults are present. The Jabal Mahanid group of ancient gold mines is on a northwest-trending vein system, and major ancient mine areas are found where the system splits or changes direction. The veins consist of zones of brecciated and crushed rock, which are generally less than 0.5 m wide but may be as wide as 1 m. These zones contain quartz and calcite stringers and commonly are along hornblende schist-serpentinite contacts; however, they also cut both units. Most aplite, pegmatite, and quartz dikes in the area are thin and discontinuous and are intruded along the vein trend. Similar veins, at the same stratigraphic interval, have been found beyond the northeastern part of the map area. The veins contain detectable gold and silver (median gold, approximately 0.14 ppm; median silver, approximately 1 ppm). Gold and

    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

This particular area is representative of a much larger area within Saudi Arabia where this agricultural practice is being applied. The water is being extracted from subsurface reserves that infiltrated deep aquifers over the Central Arabian Arch during previous geological periods, when the climate was much wetter than present. This view is an example of the use of abundant fossil water to achieve self sufficiency in food production. Note OV-102's vertical stabilizer and tail cap are visible in the view.

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

    Saudi Arabia have no nuclear industry. Nevertheless, many radioactive sources, for different purposes, have been used in the country. There is upswing in the number of companies that recruit nuclear technology in their daily work. The National Center for Radiation Protection (NCRP) takes the full commitment and responsibility for monitoring and regulating the movement of radioactive sources in the country. NCRP issues the licenses for import, export, and use of radioactive sources. It, also, protects the country from any trespassing radiation through a sizable net of early warning and radiation monitoring stations along the borders of Saudi Arabia. This paper talks about the procedures of licensing, importing, exporting of radioactive sources. It, also, sheds light on types of implementing radioactive sources in different practices encompass medicine, industry, research. The NCRP has established an electronic web site to ease the communication with all users in the country. This site is yet in the experimental stage.

    Physicians' prescribing behaviour is closely linked with patient safety and this area is poorly researched in Saudi Arabia. The objective of this study was to analyse physicians' prescribing patterns and the adequacy of noted information in the primary health care sector in Riyadh city. All medication prescriptions from 5 public (n = 1182) and 5 private (n = 1200) health centres were collected by simple random sampling during 1 working day. Antibiotics were the most commonly prescribed drugs in both sectors. The mean number of drugs per prescription was 2.08 and 2.36 in the public and private sectors respectively. Information and instructions noted on prescriptions varied considerably between private and public health centres. Similarly the medication prescribing pattern differed across the 2 health settings. Primary care physicians in Saudi Arabia need continuing training to improve their prescribing practices. PMID:21735950

    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.

    The main objective of this study was to discover the association between the intake of certain foods and the occurrence of obesity among adolescent girls in Saudi Arabia. A cross-sectional multistage sampling method was conducted among girls aged 12-19 years in Jeddah, Saudi Arabia. The total sample was 512. Obesity was calculated based on the International Obesity Task Force standards. Findings revealed that obese girls were less likely to eat fruit, vegetables, meat, chicken and dairy products than non-obese girls, but the differences were not statistically significant. However, the risk of being obese was greater for those who consumed chocolates and sweets (odds ratio=1.57) and fast foods (odds ratio=1.35) more than three times a week. Thus, programs to promote a healthy lifestyle for schoolchildren should include appropriate intervention on changing dietary habits.

    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

    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.

    Emerging trace organic chemicals (TOrCs) released into the environment via discharge of wastewater effluents have been detected in rivers and lakes worldwide, raising concerns due to their potential persistence, toxicity and bioaccumulation. This study provides the first reconnaissance of TOrC occurrence in wastewater effluents within Saudi Arabia. Four wastewater treatment plants (WWTPs 1-4) located in Western Saudi Arabia were sampled hourly over twelve-hour periods, for a total of six sampling events. All samples were analyzed for a wide range of TOrC encompassing pharmaceuticals, personal care products and household chemicals. Treatment and capacities of the plants varied from non-nitrifying to full biological nutrient removal providing a representative cross section of different types of plants operational within the country. A comparison of TOrC occurrence in effluents in Saudi Arabia with respective effluent qualities in the United States revealed similar levels for most TOrC. Overall, the occurrence of TOrC was higher at two of the plants. The higher TOrC concentrations at WWTP 1 are likely due to the non-nitrifying biological treatment process. The unique TOrC occurrence observed in the WWTP 3 effluent was unlike any other plant and was attributed to the influence of a large number of international visitors in its sewershed. The occurrence of TOrC in this plant was not expected to be representative of the occurrence elsewhere in the country. Bimodal diurnal variation expected for a range of TOrC was not observed, though some hourly variation in TOrC loading was noted for WWTP 3. Since water reclamation and reuse have received increasing interest in Saudi Arabia within the last few years, results from this study provide a good foundation in deciding whether advanced treatment is necessary to attenuate TOrC deemed to be of concern in effluents, or if natural treatment such as managed aquifer recharge provides sufficient protection to public health.

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

    Objectives: To describe the family profile of child abuse and neglect (CAN) subjects in Saudi Arabia. Methods: Data were collected retrospectively between July 2009 and December 2013 from patients’ files, which were obtained from the Child Protection Centre (CPC) based in King Abdulaziz Medical City, Riyadh, Saudi Arabia. Four main sets of variables were examined: demographics of victim, family profile, parental information, and information on perpetrator and forms of abuse. Results: The charts of 220 CAN cases were retrospectively reviewed. Physical abuse was the most common form of abuse (42%), followed by neglect (39%), sexual abuse (14%), and emotional abuse (4%). Children with unemployed fathers were 2.8 times as likely to experience physical abuse. Children living in single/step-parent households were 4 times as likely to experience physical abuse. Regarding neglect children living in larger households (≥6) were 1.5 times as likely to be neglected by their parents as were children living in smaller households (<6). Regarding sexual abuse, male children were 2.9 times as likely to be abused as were female children. Conclusions: The recent acknowledgment of CAN as a public health problem in Saudi Arabia suggests that time will be needed to employ effective and culturally sensitive prevention strategies based on family risk factors.

    Airborne particulate matter (PM) exposure is a major environmental health concern and is linked to metabolic disorders, such as cardiovascular diseases (CVD) and diabetes, which are on the rise in the Kingdom of Saudi Arabia. This study investigated changes in mouse lung gene expression produced by administration of PM10 collected from Jeddah, Saudi Arabia. FVB/N mice were exposed to 100 μg PM10 or water by aspiration and euthanized 24 h later. The bronchoalveolar lavage fluid (BALF) was collected and analyzed for neutrophil concentration and tumor necrosis factor (TNF)-α and interleukin (IL)-6 levels. RNA was extracted from lungs and whole transcript was analyzed using Affymetrix Mouse Gene 1.0 ST Array. Mice exposed to PM10 displayed an increase in neutrophil concentration and elevated TNF-α and IL-6 levels. Gene expression analysis revealed that mice exposed to PM10 displayed 202 genes that were significantly upregulated and 40 genes that were significantly downregulated. PM10 induced genes involved in inflammation, cholesterol and lipid metabolism, and atherosclerosis. This is the first study to demonstrate that Saudi Arabia PM10 increases in vivo expression of genes located in pathways associated with diseases involving metabolic syndrome and atherosclerosis.

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

    In an era of expanding health sectors and rising costs, doctors are expected to have a working knowledge of health economics to better use resources and improve outcomes and quality of health care. This article recognizes the dearth of knowledge and application of economic analyses in medical education and clinical practice in Saudi Arabia. In particular, it highlights the desirability of knowledge of health economics in ensuring certain competencies in medical education and the rationale for inviting doctors to apply knowledge of economics in Saudi Arabia. In addition, the article discusses challenges that hinder integrating health economics into clinical practice. Furthermore, the article typifies some of the important economic phenomena that physicians need to discern. Besides, the article provides implications for incorporating economic analysis into medical education and clinical practice in Saudi Arabia. Finally, the article concludes by demonstrating how health economics can enhance doctors' knowledge and recommends the country to move towards integrating health economics into medical education and clinical practice for best practice.

    Objectives: The aim of the study was to assess the knowledge and practice of implant retained restorations (IRR) among senior dental students in Saudi Arabia. Methods: Four hundred questionnaires were distributed among senior dental students of five dental schools in Saudi Arabia. Student’s knowledge was assessed regarding which implant restoration [cement retained restoration (CRR) or screw retained restoration (SRR)] better provides the desired clinical properties. Students’ practice of IRR, perception of their knowledge and need for further education related to IRR were also assessed. Descriptive statistics and chi-square test were employed to assess collected data. Results: Three hundred and fifty four senior dental students responded at a response rate of 88.5%. Thirty three percent respondents did not have any practical experience of IRR. Students showed a clear preference for CRR with regards to aesthetics (71.4%), passive fit (55.3%), fabrication ease (57.3%) and fracture resistance (40%). SRR were considered to provide better retention (59.6%), soft tissue health (51.1%) and ease of retrievability (72%). Nearly 40% of students agreed that they did not get sufficient information related to IRR in undergraduate courses. Conclusions: Clinical training of IRR is compromised in the undergraduate curriculum in dental schools of Saudi Arabia. The knowledge of dental students regarding IRR was broadly in line with current evidence. PMID:26430416

    Objective Do-not-resuscitate (DNR) orders in Saudi Arabia were first regulated by a fatwa on a national level in 1988, one that excludes the patient and their families from decision making. Although the core of this policy is taken up by all hospitals in Saudi Arabia, there is no homogeneity in implementation. Here, we appraise what interns and residents know of these policies and their attitudes toward DNR. Methods Interns and residents in four major hospitals in Jeddah, King Abdulaziz University Hospital, National Guard Hospital, King Fahad General Hospital, and King Fahad Armed Forces Hospital, were given a questionnaire in English with four blocks of questions. Results A total of 140 questionnaires were included in our study. From these questionnaires, we conclude a lack of familiarity with DNR’s policies and the fatwa and also a lack of understanding when it comes to treating DNR-labeled patients. The majority opinion was to include the patient in the decision-making process who is excluded according to the fatwa. Participants considered patients’ dignity, religious concerns, and legal concerns to be important in considering resuscitation. Conclusion We conclude a need to emphasize the issue of DNR and treatment of DNR patients in medical ethics classes in Saudi Arabia and put more effort to enact national DNR laws that include the patient in the decision-making process.

    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.

The majority of Saudi Nationals are reluctant and unwilling to donate or consent for donation. This study was undertaken to determine the knowledge and attitude towards organ donation among males in Riyadh, Saudi Arabia. A questionnaire was distributed to 223 men attending the out-patient department of the National Guard Hospital, Riyadh. A total of 205 (92%) individuals answered the questionnaire. Of them, 187 (91%) were Saudis and 18 (9%) were non-Saudis. A total of 187 (88%) had heard about organ donation of whom 80 (43%) each, had acquired this knowledge through television or radio, 16 (8%) through newspaper and magazines, seven (4%) through friends and relatives, and four (2%) through health-care workers. Of the 205 study subjects, 88 (43%) claimed they understood the concept of brain-death, 96 (47%) did not, and 19 (10%) did not respond to this question. One hundred and thirty-eight (67%) were willing to donate, and 156 (76%) were willing to receive an organ. One hundred and fifteen (56%) believed that Islam permits people to donate organs, five (2%) thought Islam does not permit organ donation, 64 (31%) gave a "don't know" answer and 21 (11%) did not attempt to answer the question. In addition, 41 (20%) thought organ donation disfigures the body. In conclusion although 67% of the respondents in this survey were willing to donate, there was a significant lack of knowledge and misconception with regard to Islamic support to, and the mutilating effects of, organ donation. Public educational programs and other measures addressing these issues may help in increasing the rate of organ donation among Saudis.

    We are utilizing receiver function and surface wave dispersion data to investigate the lithospheric shear-wave velocity structure of Saudi Arabia. The Arabian plate consists of the western Arabian shield and the eastern Arabian platform. The Arabian shield is a complicated mélange of several Proterozoic terrains, separated by ophiolite-bearing suture zones and dotted by outcropping Cenozoic volcanic rocks (so-called harrats). The Arabian platform is covered by thick Paleozoic, Mesozoic and Cenozoic sedimentary rocks. To understand the geo-dynamics and present-day geology in western Saudi Arabia, the origin and activity of the harrats needs to be investigated: are they controlled primarily by a local mantle plume underneath western Saudi Arabia or by lateral mantle flow from the Afar and (perhaps) Jordan hotspots? In our study, we first estimate Vp/Vs ratios by applying the H-κ stacking technique and construct local shear-wave velocity-depth profiles by jointly inverting teleseismic P-receiver functions and Rayleigh wave group velocities at 56 broadband stations deployed by the Saudi Geological Survey (SGS). Our results reveal significant lateral variations in crustal thickness, S-velocity, and bulk Vp/Vs ratio. The Arabian shield has, on average a ~34 km thick crust with Vs ~3.72 km/s and Vp/Vs ~1.73. Thinner crust (~25 - 32 km thick) with strong lateral variations is present along the Red Sea coast. In contrast, the Arabian platform reveals a ~41 km thick crust with Vs ~3.52 km/s and Vp/Vs ~1.77. We find anomalously high Vp/Vs ratios at Harrat Lunayyir, interpreted as solidified magma intrusions. Slow shear-velocities in the upper-mantle lid throughout the southernmost and northernmost Arabian shield suggest lateral heating from hot mantle upwellings centered beneath Afar and (perhaps) Jordan. Our findings on crustal S-velocity structures, Vp/Vs ratios, and upper-mantle lid velocities support the hypothesis of lateral mantle flow from the Afar and (perhaps

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

    Unlike sub-optimal prescribing, rational prescribing, coupled with certain indicators, is associated with improved safety in drug use in terms of selecting appropriate drug for prescribing, better quality of life for patients and cost-effective care. Medication prescribing is a relatively unexplored area of research in Saudi Arabia and until now most studies have been in the secondary and tertiary health care system. This paper is the second of 3 review articles that form the background for a series of 5 interconnected studies of prescribing patterns and medication errors in the public and private primary health care sectors of Saudi Arabia. A MEDLINE search was conducted to identify papers published in peer-reviewed journals over the previous 3 decades. The paper reviews rational prescribing with its indicators, suboptimal prescribing, classification of medication errors, and how to achieve quality in health care prescribing worldwide and in Saudi Arabia.

    Turaif area located in the Northern border region of Saudi Arabia is one of the most important regions of the Kingdom. This work was proposed to throw light on the diversity of lizard fauna investigated through the collection and subsequent identification of specimens from different localities of Turaif region of Kingdom of Saudi Arabia. Sixteen species of lizards belonging to 5 families (Agamidae, Gekkonidae, Lacertidae, Scincidae and Varanidae) were recorded. Lacertidae was the most common family. Three species of lizards namely Acanthodactylus orientalis, Acanthodactylus scutellatus and Acanthodactylus grandis were reported for the first time in the Turaif region of Saudi Arabia. The geographical distribution of the collected species within this province was mapped. PMID:27579015

    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.

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

    Objectives: To identify the retention protocols practiced by orthodontists in Saudi Arabia, and the factors affecting retainer choice. Methods: This cross-sectional study took place between February and March of 2015 at the College of Dentistry, University of Dammam, Dammam, Saudi Arabia. A previously tested electronic survey of 34 items was sent to all 1,200 orthodontic members of the Saudi Orthodontic Society. The questionnaire elicited data on the subjects’ demographics, orthodontic treatment practices, retention, and post-retention protocols. Results: One hundred and sixty-seven (13.9%) responses were received during the study period. The results showed predominant use of Hawley in the maxillary arch (61.3%), and fixed lingual in the mandibular arch (58.5%). Approximately 90.3% recommended full-time maxillary removable retainer wear. Overall, orthodontists who performed fewer extractions tended to use fixed retainers, and those who performed more extractions used removable retainers (p=0.018). Interproximal enamel reduction was used by 28% of the respondents as an adjunct procedure to enhance retention. Approximately 64% practiced a post-retention phase of retainer wear. Participants who used removable retainers most commonly prescribed lifetime retention. Conclusion: Hawley in the maxilla, and fixed lingual in the mandible were the most common retention protocols prescribed. Lifetime retention was the most common choice for participants who used removable retainers, especially when extractions were carried out. PMID:27464868

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

    Objective. To determine the prevalence, risk factors, characteristics, and treatment practices of known adult hypertensives in Saudi Arabia. Methods. Cross-sectional community-based study using the WHO stepwise approach. Saudi adults were randomly chosen from Primary Health Care Centers catchment areas. Data was collected using a questionnaire which included sociodemographic data, history of hypertension, risk factors, treatment practices, biochemical and anthropometric measurements. Collected data was cheeked, computer fed, and analysed using SPSS V17. Results. Out of 4719 subjects (99.2% response), 542 (11.5%) subjects were known hypertensives or detected by health workers in the past 12 months. Hypertension was significantly associated with age, gender, geographical location, education, employment, diabetes, physical inactivity, excess body weight, and ever smoking. Multiple logistic analysis controlling for age showed that significant predictors of hypertension were diabetes mellitus, ever smoking, obesity, and hypercholesteremia. Several treatment modalities and practices were significantly associated with gender, age, education, and occupation. About 74% were under prescribed treatment by physicians, 62% on dietary modification, 37% attempted weight reduction, 27% performed physical exercise, and less than 7% used herbs, consulted traditional healers or quitted smoking. Income was not significantly associated with any treatment modality or patient practices. Conclusion. Hypertension (known and undetected) is a major chronic health problem among adults in Saudi Arabia. Many patients' practices need changes. A comprehensive approach is needed to prevent, early detect, and control the disease targeting, the risk factors, and predictors identified. PMID:21318133

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

    2010-01-01

    Summary Six soil samples from natural and cultivated sites of Saudi Arabia were investigated for ciliate diversity, using the non-flooded Petri dish culture method, live observation, and silver impregnation. We identified 135 species, all new for the fauna of Saudi Arabia, of which seven were undescribed: Spathidium alqasabi nov. spec.; Enchelyodon alqasabi nov. spec.; Metauroleptus arabicus nov. gen., nov. spec.; Pseudohemisincirra arabica nov. gen., nov. spec.; Saudithrix terricola​ Berger, Al-Rasheid and Foissner, 2006; Oxytricha arabica nov. spec.; and Erimophrya monostyla nov. spec. Based on Spathidium alqasabi, S. seppelti foissneri​ Vd’ačný et al., 2006 and S. seppelti etoschense​ Foissner et al., 2002 are raised to species rank; for the latter, a new name is required to avoid homonymy: Spathidium fraterculum nov. nom. The new genus Metauroleptus, which possesses two long and two to three short ventral cirral rows, generates all dorsal kineties intrakinetally and produces caudal cirri exclusively in dorsal kinety 1. Metauroleptus belongs to the hypotrichs, while family classification remains doubtful. The same applies to the new hypotrich genus Pseudohemisincirra, which has frontoventral and transverse cirri, while buccal cirri and caudal cirri are absent. The number of species contained in Saudi Arabian soils, including sand dunes, is in the range reported from other regions of the earth, suggesting that ciliates are well adapted to dry habitats, possibly mainly by their ability to produce very resistant resting cysts, most surviving for a long time due to reduced metazoan predation.

    In 1936, geologic work related to the Tertiary System in western Saudi Arabia began with a study of the Umm Gerad barite deposit by K. S. Twitchell. In 1944, a study focusing specifically on Tertiary rocks was conducted by Steineke and others near Jiddah. Small-scale mapping of Tertiary sequences began in 1950 in southwestern Saudi Arabia and later in northern 3audi Arabia as part of the Kingdom's early mapping program. These studies were part of a larger program being directed by the Government of Saudi Arabia in connection with mineral resource investigations. In the mid- to late-1960's, the Bureau de Recherches Geologiques et Minieres discovered mineralized Tertiary rocks al Jabal Dhaylan and began a study, which continues to the present, of both the Tertiary rocks and the mineralization. Following a number of early local studies, in 1973 the U.S. Geological Survey began detailed study of the Tertiary layered rocks along the Red Sea coastal plain south of Jiddah. More recently, Riofinex and Seltrust have been exploring for selected commodities in Tertiary sequences of northwestern Saudi Arabia and the Red Sea coastal plain. Results of these studies, including work by the Saudi Arabian Directorate General of Mineral Resources and the Saudi government agency preceding it, are summarized in this report. Characteristics of the Tertiary rocks south of lat 23? N. and the Tertiary mineral deposits of western Saudi Arabia are also summarized. Recommendations are made for future geologic studies and mineral assessment of the Tertiary rocks of western Saudi Arabia.

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

    The objective of this paper is to investigate the experiences of using a digital marketing platform to promote the use of an internet based health encyclopedia in Saudi Arabia. Key informant interviews, meeting documentation, and Google Analytics were the data collection sources used in the study. Findings show that using a digital marketing platform led to a significant increase in the number of visitors to the health encyclopedia. The results demonstrate that digital marketing platforms are effective tools to be used for promoting internet based health education interventions. Future work will examine long-term educational impacts and costs in using digital marketing platforms to promote online healthcare sites in Saudi Arabia.

    Ash Shuqayq (Saudi Red Sea coast) is approximately 28km long and characterised by narrow rocky headlands with intermittent pocket beaches. Fifty-two sediment samples from six different environments (beach, dune, sabkha, tidal/lagoon, offshore and wadi) were analysed. Testing showed that beach and dune sands are mainly medium to fine grained, with some very coarse sand (MZ=-0.59ø). Both beach and dune sands are moderately well to moderately sorted, although some are poorly sorted due to an influx of wadi sediments. Sediment source together with littoral reworking contributed to grain size variation. Carbonate content varied between 1.5% and 23%, whilst the organic content varied between 1.1% and 13%. Spatial analysis showed increasing southward carbonate and organic content, with both correlated (r=0.57). Sabkha sediments had significantly higher carbonate percentages (t=2.898; df=18; p<0.01) and results suggested origins are similar for both UAE Arabian Sea and Saudi Arabian Red Sea coasts. X-ray diffractions show beach and dune sediments are mainly composed of detrital quartz and plagioclase feldspar with uncommon amounts of chlorites. Analysis of sediment characteristics, composition and shoreline distribution alongside coastal processes, indicate that high chlorite levels are probably caused by desalination processes. Due to human and ecosystem health consequences and the likely increased demand for desalination plants, similar analyses should be undertaken elsewhere, e.g. the Mediterranean. PMID:22353176

    Ash Shuqayq (Saudi Red Sea coast) is approximately 28km long and characterised by narrow rocky headlands with intermittent pocket beaches. Fifty-two sediment samples from six different environments (beach, dune, sabkha, tidal/lagoon, offshore and wadi) were analysed. Testing showed that beach and dune sands are mainly medium to fine grained, with some very coarse sand (MZ=-0.59ø). Both beach and dune sands are moderately well to moderately sorted, although some are poorly sorted due to an influx of wadi sediments. Sediment source together with littoral reworking contributed to grain size variation. Carbonate content varied between 1.5% and 23%, whilst the organic content varied between 1.1% and 13%.

    INTRODUCTION: The prevalence of sleepy driving and sleep-related accidents (SRA) varies widely, and no data exist regarding the prevalence of sleepy driving in Saudi Arabia. Therefore, this study was designed to determine the prevalence and predictors of sleepy driving, near-misses, and SRA among drivers in Saudi Arabia. MATERIALS AND METHODS: A questionnaire was developed to assess sleep and driving in detail based on previously published data regarding sleepy driving. The questionnaire included 50 questions addressing socio-demographics, the Epworth Sleepiness Scale (ESS), driving items, and the Berlin Questionnaire. In total, 1,219 male drivers in public places were interviewed face-to-face. RESULTS: The included drivers had a mean age of 32.4 ± 11.7 years and displayed a mean ESS score of 7.2 ± 3.8. Among these drivers, 33.1% reported at least one near-miss accident caused by sleepiness. Among those who had actual accidents, 11.6% were attributed to sleepiness. In the past six months, drivers reported the following: 25.2% reported falling asleep at least once during, driving and 20.8% had to stop driving at least once because of severe sleepiness. Young age, feeling very sleepy during driving, and having at least one near-miss accident caused by sleepiness in the past six months were the only predictors of accidents. CONCLUSION: Sleepy driving is prevalent among male drivers in Saudi Arabia. Near-miss accidents caused by sleepiness are an important risk factor for car accidents and should be considered as a strong warning signal of future accidents. PMID:25276244

    In recent advertent and inadvertent weather modification studies, a considerable effort has been made to understand the impact of varying aerosol properties and concentration on cloud properties. Significant uncertainties exist with aerosol-cloud interactions for which complex microphysical processes link the aerosol and cloud properties. Under almost all environmental conditions, increased aerosol concentrations within polluted air masses will enhance cloud droplet concentration relative to that in unperturbed regions. The interaction between dust particles and clouds are significant, yet the conditions in which dust particles become cloud condensation nuclei (CCN) are uncertain. In order to quantify this aerosol effect on clouds and precipitation, a field campaign was launched in the Asir region of Saudi Arabia as part of a Precipitation Enhancement Feasibility Study. Ground measurements of aerosol size distributions, hygroscopic growth factor, CCN concentrations as well as aircraft measurements of cloud hydrometeor size distributions were done in the Asir region of Saudi Arabia in August 2009. Research aircraft operations focused primarily on conducting measurements in clouds that are targeted for cloud top-seeding, on their microphysical characterization, especially the preconditions necessary for precipitation; understanding the evolution of droplet coalescence, supercooled liquid water, cloud ice and precipitation hydrometeors is necessary if advances are to be made in the study of cloud modification by cloud seeding. Non-precipitating mixed-phase clouds less than 3km in diameter that developed on top of the stable inversion were characterized by flying at the convective cloud top just above the inversion. Aerosol measurements were also done during the climb to cloud base height. The presentation will include a summary of the analysis and results with a focus on the unique features of the Asir region in producing convective clouds, characterization of the

    Keeping up-to-date with new health information is a necessity for healthcare professionals. Today, social media platforms such as Twitter, among others, are important sources for healthcare professionals. Within the Arab world, little is known about how healthcare professionals use social media to update their healthcare information. This study aims to estimate the prevalence of healthcare professionals, primarily physicians, in seeking online health information in Saudi Arabia. We conducted a web-based survey among Twitter participants between February 1 and March 10, 2015. The primary outcome measures were the self-reported rates of Twitter use, perceived effects, and the influence of Twitter information on clinical practice. Our results revealed that the prevalence rate of physician's seeking online health information was 79% (n=166); the majority of them (71.4%, n=150) reported that Twitter had a significant impact in increasing their medical knowledge and in improving their clinical practice. Over half of the survey participates reported the need for investment in establishing trustworthy and credible health Twitter accounts. The participants reported that their preference for social media health accounts that focus on women's health, non-communicable disease and psychotherapy (20%, 18.1% and 14.5% respectively). The findings showed clearly that seeking web-based medical information through social media is popular among physicians, in general, but especially among younger physicians in Saudi Arabia. The study findings indicate to the necessity for further research on designing and implementing a national social media based educational outreach program to provide evidence-based healthcare information and improve healthcare providers' knowledge and skills in Saudi Arabia.

    BACKGROUND: Modern civilization and the sharp rise in living standards have led to dramatic changes in trauma pattern in Saudi Arabia. This study aimed to describe the different patterns of injuries of patients attending the Emergency Department of Jazan General Hospital (JGH) in the southwest corner of Saudi Arabia. METHODS: A total number of 1 050 patients were enrolled in the study. A pre-organized data sheet was prepared for each patient attended the Emergency Department of JGH from February 2012 to January 2013. It contains data about socio-demographics, trauma data, clinical evaluation results, investigations as well as treatment strategies. RESULTS: The mean age of the patients was 25.3±16.8 years. Most (45.1%) of the patients were at age of 18–30 years. Males (64.3%) were affected by trauma more common than females. More than half (60.6%) of the patients were from urban areas. The commonest kind of injury was minor injury (60%), followed by blunt trauma (30.9%) and then penetrating trauma (9.1%). The mean time from the incident to arrival at hospital was 41.3±79.8 minutes. The majority (48.2%) of the patients were discharged after management of trivial trauma, whereas 2.3% were admitted to ICU, 7.7% transferred to inpatient wards, and 17.7% observed and subsequently discharged. The mortality rate of the patients was 2.6%. CONCLUSION: Trauma is a major health problem, especially in the young population in Saudi Arabia. Blunt trauma is more frequent than penetrating trauma, with road traffic accidents accounting for the majority. PMID:25802567

    Human papillomavirus (HPV) is closely associated with cervical cancer that the incidence of this tumor is regarded as a surrogate marker for HPV infection in countries lacking epidemiological studies. HPV is also implicated in subsets of anogenital and oropharyngeal cancers. Although cervical cancer is the third most common cancer in women worldwide, its reported incidence is low in Saudi Arabia, ranking number 12 between all cancers in females and accounts only for 2.4% of all new cases, despite the lack of national screening programs. However, the limited available studies from Saudi Arabia indicate that HPV prevalence and genotypes’ distribution in invasive cervical cancer show similar pattern as in the world. Cytology screening (Pap smear) and HPV vaccinations are the two preventive measures against cervical cancer. The two available vaccines are effective against the two most common HPV genotypes (HPV-16 and -18). Since 92% of cervical tumors in the Kingdom are infected with HPV of which 78% are HPV-16 and -18 genotypes, vaccination is expected to protect against more than two-third of cervical cancers in Saudi Arabia. Nevertheless, due to its low incidence (2.1/100,000 women), a proper cost-effectiveness analysis is required to justify the implementation of a costly vaccine bearing in mind that HPV could potentially be associated with about 3% of all cancers. However, further studies are needed to ascertain the real prevalence of HPV at the population level at large, its association with various types of cancers, and also the impact of local tradition and emerging behavioral trends that could affect HPV transmission and consequently the effectiveness of applying national vaccination program.

    In the absence of permanent rivers or bodies of water, half of the Saudi Arabia domestic water consumption is provided through desalination. The other half is derived from groundwater. Groundwater from the Disi aquifer is already used for drinking water in parts of Jordan and, more extensively, in Saudi Arabia, where it is known as the Saq aquifer. Some of the geological analyses of the host sandstone aquifer rocks show (228)Ra and (226)Ra. The usefulness of chromosomal aberrations analysis as a bioindicator for ionising radiation effect was tested in underground water well workers of Saudi Arabia in this industry producing technologically enhanced naturally occurring radioactive material. The incidence of chromosomal aberrations was evaluated using the metaphase analysis method in the lymphocytes of peripheral blood of 10 persons working in underground water well. The age range of the workers was 25-40 y and their duration of service ranged from 3-7 y. For comparison, blood samples were also collected from 10 subjects (controls) who belonged to same age and socioeconomic status. Subjects in the both groups were non-smokers and non-alcoholics. Results showed that the mean frequencies of dicentrics and acentrics in underground water well workers are significantly higher than those in controls. The higher frequency of chromosomal aberration in lymphocytes of underground water well workers compared with controls could be due to the accumulative effect of radiation. The results of this study demonstrated that occupational exposure to radiation leads to a significant induction of cytogenetic damage in peripheral lymphocytes of workers engaged in underground water well.

    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.

    Background Good medication labeling practices are imperative to ensure safe medication use. Non-adherence to labeling protocols is reported as one major source of medication errors. Objective This study was intended to evaluate and compare adherence to labeling guidelines for dispensed medications among the hospitals of the five different health sectors in the city of Riyadh, Saudi Arabia. Methods A descriptive, cross-sectional analysis was conducted among 14 public hospitals in the city of Riyadh, Saudi Arabia. Labeling guidelines issued by the Institute for Safe Medication Practices were used as a standard assessment tool. A total of 218 medication labels were collected and evaluated for labeling adequacy. Descriptive statistics were used to elaborate the study findings. All analyses were performed with Microsoft Access. Results The study showed a substantial rate of adherence to the labeling guidelines. In terms of the established criteria, community and mail orders were reported to adhere strongly (90.5%), whereas injectables adhered least to the labeling guidelines. The labeling format, contents of the label, instructions on the labels, abbreviations used on the labels and drug names were also consistent with the guidelines (80.0%, 84.0%, 88.0%, 97.7% and 85.5%, respectively). Organizations belonging to the public sector reported a higher level of adherence (⩾80.0%) than the level found for private hospitals (70.0%). Conclusion In Riyadh hospitals, medication labeling following the guidelines issued by the Institute for Safe Medication Practices, is well accepted and rationally practiced. However, a nationwide study is recommended to evaluate if the guidelines are followed throughout Saudi Arabia. PMID:24227953

    We undertook breeding surveys between 2010 and 2011 to assess the status of breeding birds on 16 islands in the northern Saudi Arabia. Sixteen bird species were found breeding at three different seasons; i.e. winter (Osprey), spring (Caspian and Saunder’s Terns), and summer (Lesser Crested, White-cheeked, Bridled Terns). It is postulated that food availability is an important factor influencing the breeding of seabirds in the northern Saudi Arabian Red Sea. Several species laid eggs earlier in northern parts of the Red Sea than in southern parts. The predicted increases in temperatures (Ta) could have a negative effect on species survival in the future, especially on those whose nests that are in the open. Finally, disturbance, predation and egg collection were probably the main immediate threats affecting the breeding seabird species in the northern Red Sea. PMID:24955009

    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.

    Biobanking entails large-scale collection of human biological specimens that are linked to the donors' health and personal information, and has several applications in clinical research. Human biological specimens, such as blood, urine and tissue, have become immensely important to medical research: they offer a valuable source of genetic material that researchers can use to identify disease-associated genetic variation and to determine interactions between genes and environmental factors. Identification of genetic contributions to disease can lead to the development of new diagnostic tests and targeted treatments. Over the last decade, both common diseases and rare genetic disorders have been reported in Saudi Arabia. The need to generate extensive genetic data on these diseases has led to the establishment of several Saudi Arabian biobanks. Fortunately, these vital efforts have the support of the Saudi Government and researchers. However, the success of any biobank also requires public support and the willingness of the population to donate their biological material along with information on their medical records. Thus, the Saudi public needs to be informed of the benefits of maintaining biobanks, their participation needs to be encouraged through donation of biological material, and any public concerns regarding the confidential treatment of medical data need to be addressed. This article reviews the most common genetic diseases identified in the Saudi population, it describes biobanks and it examines how biobanks can support biomedical research in the area. Moreover, this article proposes measures that might help to increase public awareness of biobanks and the preparedness of the Saudi Arabian population to donate biological material. PMID:27594298

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

He presented with non-healing nodulo-ulcerative lesions with a "volcanic crater" on the lower limbs. It was clearly cutaneous leishmaniasis - a rare disease in China - as reflected by the patient's clinical history, the lesions' morphology, histopathological examination, culture and PCR analysis of the lesions. The patient was completely cured after two cycles of sodium stibogluconate treatment. This case report demonstrates that dermatologists should be aware of sporadic cutaneous leishmaniasis cases in non-endemic areas. PMID:27438208

    Results are presented from the analyses of small ballistically dispersed melt samples (occurring in the form of aerodynamically shaped spheres, dumbbells, and teardrops) from the Wabar Crater (Saudi Arabia) and of melts from the Wabar and Nejed meteorites. On the basis of the data obtained and of models for crater forming processes it is concluded that the ballistically-dispersed glasses were formed from material at shallow levels in the target zone where temperatures were higher and where intimate physical contact with the disrupting impactor was achieved. Siderophile element fractionation was completed early, while the impactor was undergoing decompression and prior to mixing with the target glasses.

It was clearly cutaneous leishmaniasis - a rare disease in China - as reflected by the patient's clinical history, the lesions' morphology, histopathological examination, culture and PCR analysis of the lesions. The patient was completely cured after two cycles of sodium stibogluconate treatment. This case report demonstrates that dermatologists should be aware of sporadic cutaneous leishmaniasis cases in non-endemic areas. PMID:27438208

    Near Jiddah, Saudi Arabia, a heavy-minerals survey was made in the Precambrian sediments o# the Fatima Formation. Samples measuring 0.25 cubic meters were taken in a net related to the drainage system and. washed in a sluice. The concentrates were tested. for 29 elements which included precious and. base metals, rare earths, and. radioactive elements. Only 17 elements were detected in the samples and all values were normal. The concentrates contained only common species o# heavy density resistate minerals. The survey showed that the area is not a favorable one in which to search for ores of the elements tested.

  5. Age discrimination among basalt flows using digitally enhanced LANDSAT imagery. [Saudi Arabia

    Digitally enhanced LANDSAT MSS data were used to discriminate among basalt flows of historical to Tertiary age, at a test site in Northwestern Saudi Arabia. Spectral signatures compared favorably with a field-defined classification that permits discrimination among five groups of basalt flows on the basis of geomorphic criteria. Characteristics that contributed to age definition include: surface texture, weathering, color, drainage evolution, and khabrah development. The inherent gradation in the evolution of geomorphic parameters, however, makes visual extrapolation between areas subjective. Therefore, incorporation of spectrally-derived volcanic units into the mapping process should produce more quantitatively consistent age groupings.

    Emerging trace organic chemicals (TOrCs) released into the environment via discharge of wastewater effluents have been detected in rivers and lakes worldwide, raising concerns due to their potential persistence, toxicity and bioaccumulation. This study provides the first reconnaissance of TOrC occurrence in wastewater effluents within Saudi Arabia. Four wastewater treatment plants (WWTPs 1-4) located in Western Saudi Arabia were sampled hourly over twelve-hour periods, for a total of six sampling events. All samples were analyzed for a wide range of TOrC encompassing pharmaceuticals, personal care products and household chemicals. Treatment and capacities of the plants varied from non-nitrifying to full biological nutrient removal providing a representative cross section of different types of plants operational within the country. A comparison of TOrC occurrence in effluents in Saudi Arabia with respective effluent qualities in the United States revealed similar levels for most TOrC. Overall, the occurrence of TOrC was higher at two of the plants. The higher TOrC concentrations at WWTP 1 are likely due to the non-nitrifying biological treatment process. The unique TOrC occurrence observed in the WWTP 3 effluent was unlike any other plant and was attributed to the influence of a large number of international visitors in its sewershed. The occurrence of TOrC in this plant was not expected to be representative of the occurrence elsewhere in the country. Bimodal diurnal variation expected for a range of TOrC was not observed, though some hourly variation in TOrC loading was noted for WWTP 3. Since water reclamation and reuse have received increasing interest in Saudi Arabia within the last few years, results from this study provide a good foundation in deciding whether advanced treatment is necessary to attenuate TOrC deemed to be of concern in effluents, or if natural treatment such as managed aquifer recharge provides sufficient protection to public health.

    Objective: The purpose of this study was to investigate the association between knowledge and attitude with health-related quality of life (HRQoL) among patients with type 2 diabetes mellitus in Riyadh, Saudi Arabia. Materials and Methods: A cross-sectional descriptive study was undertaken with a cohort of 75 patients attending the University Diabetic Center at King Abdulaziz University Hospital, Riyadh, Saudi Arabia. The EuroQoL-five-dimensional (EQ-5D) scale was used to assess HRQoL. EQ-5D was scored using values derived from the UK general population survey. The brief diabetic knowledge test in questionnaire format developed by the University of Michigan Diabetes Research and Training Center and the attitude toward self-care questionnaire based on the diabetic care profile were used. Results: Fifty-eight (77.35%) respondents were male with a mean 12.6 ± 8.4 years of a history of diabetes. Thirty-four (45.3%) were in the age group of 45–55 years with a mean age of 54 ± 9.2 years. A moderate level of HRQoL (0.71 ± 0.22) was recorded in the study cohort. The mean EQ-5D score was lower in females compared to male patients (0.58 ± 0.23 vs. 0.74 ± 0.20). The mean score of Michigan Diabetic Knowledge Test was 8.96 ± 2.1 and the median score was 9.00. Of 75 diabetic patients, 14.7% had poor knowledge; 72% had moderate knowledge, and only 13.3% had good knowledge. The average attitude score of all respondents was 6.38 ± 2.11. There was a significant positive association between attitude and EQ-5D score. Conclusion: HRQoL and knowledge scores were moderate in type 2 diabetic patients in Riyadh, Saudi Arabia. Patient attitude toward the disease was positive, and this was positively associated with HRQoL; most respondents believed they are responsible for their care. It is likely that a high quality of diabetes self-management education program will provide benefits and affect significantly on type 2 diabetes patients in Saudi Arabia. PMID:27413347

    Over the past couple of years, the frequency and magnitude of flash floods are increasing in the Kingdom of Saudi Arabia. For effective planning and mitigation purposes, it is necessary to identify and visualize areas that are vulnerable to the flooding. In this paper, we will first create a flash flood social and physical vulnerability index for the city of Riyadh based on physical and social-economic data. Building upon the index, the areas of Riyadh that are highly vulnerable to flash floods will be identified and mapped using Geographic Information Systems (GIS). Finally, possible mitigation measures that can be used to reduce the impacts of flooding will be discussed in details.

    Objectives: To review and analyze the pattern of breast cancer (BC) in the Kingdom of Saudi Arabia (KSA). Methods: A retrospective descriptive epidemiological review of BC of all diagnosed Saudi female cases from January 1990 to December 2014 was conducted at the Faculty of Sciences, Department of Biology, University of Tabuk, Tabuk, KSA. This report contains information obtained from the Saudi Cancer Registry and from King Faisal Specialist Hospital and Research Center. Results: The number of women with BC increased steadily from 1990-2010. On the basis of the number of cases, the percentage distribution of BC appears to be increasing. There were 1152 female BC cases in 2008 in comparison with 1308 in 2009, and 1473 in 2010. Breast cancer ranked first among females accounting for 27.4% of all newly diagnosed female cancers (5378) in the year 2010. The average age at the diagnosis of BC was 48; weighted average was 49.8, and range 43-52. Conclusion: Among Saudi patients, there was a significant increase in the number of cases of BC, which occurs at an earlier age than in Western countries. Continued vigilance, mammographic screening, and patient education are needed to establish early diagnosis and perform optimal treatment. PMID:26446327

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

    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.

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

    Background Saudi Arabia annually reports a relatively higher proportion (28–32%) of extrapulmonary tuberculosis (EPTB) cases in comparison to other global regions. However, there were few studies conducted so far to determine the sociodemographic factors and clinical manifestations associated with EPTB at a nationwide level. Methodology A retrospective analysis on culture positive EPTB isolates collected from all the provinces of the country were conducted for a period of 12 months to determine the spectrum of diversity in EPTB infection sites and the confounding factors. A detailed clinical and demographical data analysis was carried out along with first line drug susceptibility testing. Principal Findings Intra-thoracic and extra-thoracic lymph nodes (44.6%) were the most common sites of infection followed by gastrointestinal (17.3%) and central nervous systems (11.8%). Male patients were mostly infected (58.8%), in contrary to the global trend. Any drug resistance was observed in 23.1% isolates with a 2.1% of multi-drug resistance. HIV reactivity was found only in 2.2% cases. A higher proportion of Saudi nationals (58.8%) were infected compared to the immigrants, descending mostly from South Asia (34.4%) and South East Asia (31.2%). The Saudi population predominated with all forms of EPTB while immigrants showed no significant variations. Conclusions Saudi Arabia faces a serious threat from EPTB, particularly to the central nervous system and gastrointestinal systems. More effective diagnostic strategies and control measures must be implemented to reduce the high rate of EPTB in the country. In addition, these findings warrant further detailed research to explore all related comorbid conditions of EPTB development, particularly the host-related factors. PMID:25647300

    Objectives: To investigate whether healthy foods in Saudi Arabia cost more compared with less healthy options. Method: This is a cross-sectional study conducted in Riyadh, Saudi Arabia during June and July 2015. The study targeted well-known market chains in the city of Riyadh. The selection of food items was purposive to include healthy and less healthy food items in each category. Price, caloric value, salt, fat, sugar, and fiber contents for each food item were collected. To test for the correlation between nutritional contents and average price, Spearman’s correlation coefficients were calculated. The Mann-Whitney U test was used to test for the presence of average price difference between healthy and less healthy food items. Results: A total of 162 food items were collected. Sixty-six food items were classified as healthy compared with 96 less healthier options. The calculated correlation coefficients indicate an association between increased cost of food with increased caloric values (0.649 p=0.0000001), increased fat content (0.610 p=0.0000003), and increased salt contents (0.273 p=0.001). Prices of food items with higher fiber contents showed a weaker association (0.191 p=0.015). The overall average cost of healthy food was approximately 10 Saudi riyals cheaper than less healthy food (p=0.000001). Conclusion: The findings of the study suggest that the cost of healthy food is lower than that of less healthy items in the Saudi market. PMID:27570859

    Background: Good communication skills and rapport building are considered the cardinal tools for developing a patient-doctor relationship. A positive, healthy competition among different health care organizations in Saudi Arabia underlines an ever increasing emphasis on effective patient-doctor relationship. Despite the numerous guidelines provided and programs available, there is a significant variation in the acceptance and approach to the use of this important tool among pediatric residents in this part of the world. Objective: To determine pediatric residents' attitude toward communication skills, their perception of important communication skills, and their confidence in the use of their communication skills in the performance of their primary duties. Materials and Methods: A cross-sectional study was conducted among all pediatrics trainee residents working in 13 different hospitals in Saudi Arabia. A standardized self-administered questionnaire developed by the Harvard Medical School was used. Results: A total of 297 residents out of all trainees in these centers participated in the data collection. The 283 (95%) residents considered learning communication skills a priority in establishing a good patient-doctor relationship. Thirty four percent reported being very confident with regard to their communication skills. Few residents had the skills, and the confidence to communicate with children with serious diseases, discuss end-of-life issues, and deal with difficult patients and parents. Conclusion: Pediatric residents perceive the importance of communication skills and competencies as crucial components in their training. A proper comprehensive communication skills training should be incorporated into the pediatric resident training curriculum. PMID:26929729

    Indoor gamma radiation measurement at dwellings of Riyadh city in Saudi Arabia using TLD has been performed. Measurements were carried out from October 2004 to June 2005. The city was divided into five sectors, for four categories of bed rooms, living rooms, bathrooms and kitchens. The indoor gamma annual absorbed dose of Riyadh city is in the range from 303+/-57 to 700+/-38microGyy(-1) with an average value of 455.1+/-45microGyy(-1). The calculated corresponding annual effective dose to the adult population of the locations will vary from 212+/-40 to 490+/-27microSvy(-1) with an average value of 318.57+/-31microSvy(-1).(222)Rn concentration was measured at dwellings of Riyadh city in Saudi Arabia to estimate effective annual dose to the public from (222)Rn and its progeny. The (222)Rn concentrations were measured using CR-39 detector. The range of annual mean (222)Rn concentrations for all sites was 2-69Bqm(-3) with an average of 18.4Bqm(-3). The effective annual dose was estimated to be 0.46mSvy(-1).

    An indoor radon survey was carried out recently in nine cities of Saudi Arabia using nuclear track detectors (NTD)-based passive radon detectors. The survey included Qatif City in the Eastern Province of Saudi Arabia, where 225 detectors were collected back successfully. It was found that the average indoor radon concentration in the dwellings was 22 +/- 15 Bq m(-3). However, one of the dwellings showed an anomalous radon concentration of 535 +/- 23 Bq m(-3). This finding led to a detailed investigation of this dwelling using active and passive techniques. In the active technique, an AlphaGUARD 2000 PRQ radon gas analyser was used. In the passive technique, CR-39 based passive radon detectors were used in all the rooms of the dwelling. Radon exhalation from the wall and the floor was also measured using the can technique. The active measurement confirms the passive one. Before placing the passive radon detectors in all the rooms of the two-storey building, the inhabitant was advised to ventilate his house regularly. The radon concentration in the different rooms was found to vary from 124 to 302 Bq m(-3). Radon exhalation from the floor and the wall of the room with the anomalous radon concentration was found to vary from 0.5 to 0.8 Bq m(-2) h(-1). These low radon exhalation rates suggest that the anomalous radon concentration is most probably due to underground radon diffusion into the dwelling through cracks and joints in the concrete floor.

    Recently acquired seismic data reinterpreted well information in northwest Saudi Arabia extends outcropping Lower Silurian to Upper Ordovician Zarqa/Sarah glacial and periglacial deposits into the subsurface. These deposits range from northeast-trending outwash-filled channels deeply incised into the underlying Ordovician Qasim and the Cambrian-Ordovician Saq Formation in the east. A southwest source for these sediments is implied by this new data. This supports previously interpreted source directions mapped from outcrop. It also correlates with the position of the Arabian plate relative to known Gonwanaland ice caps during the Early Silurian-Late Ordovician. The recognition of glacial outwash sediments in the subsurface provides new insight into the continuity and environments of deposition of the Qasim Formation members in northwest Saudi Arabia. The hydrocarbon-prone Lower Silurian Qusaiba Member of the Qalibah Formation overlies the Zarqa/Sarah Formations. The Qusaiba represents a rapid transgression of the Paleo-Tethys Sea during the final melting of the Gondwanaland ice caps. The seal-source characteristics of the Qusaiba Member, combined with the good porosity and permeability of the underlying outwash deposits, suggest a prospective hydrocarbon exploration play. Gas is produced from this reservoir in the Risha field of eastern Jordan.

    Our TLC study of the volatile oil isolated from Mentha longifolia showed a major UV active spot with higher Rf value than menthol. Based on the fact that the components of the oil from same plant differ quantitatively due to environmental conditions, the major spot was isolated using different chromatographic techniques and identified by spectroscopic means as pulegone. The presence of pulegone in M. longifolia, a plant widely used in Saudi Arabia, raised a hot debate due to its known toxicity. The Scientific Committee on Food, Health & Consumer Protection Directorate General, European Commission set a limit for the presence of pulegone in foodstuffs and beverages. In this paper we attempted to determine the exact amount of pulegone in different extracts, volatile oil as well as tea flavoured with M. longifolia (Habak) by densitometric HPTLC validated methods using normal phase (Method I) and reverse phase (Method II) TLC plates. The study indicated that the style of use of Habak in Saudi Arabia resulted in much less amount of pulegone than the allowed limit. PMID:27087088

    In the Eastern Province of the Kingdom of Saudi Arabia from south of Al Hasa oasis (about lat 25? N., long 50? E.) north to near the southern border of the neutral zone between Saudi Arabia and Kuwait (about lat 28? N., long 48? E.), sabkhah-associated brines form either by solar evaporation of near-surface ground water or by dissolution of previously precipitated saline minerals in the subsurface. Most sabkhah-associated brines have evolved from fresher ground water by the process of solar evaporation. One of the major controls of sulfate, calcium, and bicarbonate concentrations in brines is equilibrium reactions of these ions with authigenic minerals in sabkhah sediments. Although equilibrium reactions also provide some control of concentrations of magnesium, potassium, sodium, and chlorine, the concentrations of these elements in brines are controlled primarily by the degree to which the solutions have evaporated. Salt for industrial use in the Eastern Province is currently supplied from the Ra's al Qurayyah and Aba al Hamam bedded salt deposits, both of which are naturally exposed. At Jayb Uwayyid, a bedded salt deposit approximately 3.5 m below the sabkhah surface is not currently exploited. Except on a small scale, brines in the Eastern Province are not being utilized, either directly or for the production of salt. The Jayb Uwayyid deposit has some potential for industrial utilization of brine and salt, and further exploration for this type of salt deposit is probably warranted.

    The prevalence of obesity among adults in Saudi Arabia increased from 22% in 1990-1993 to 36% in 2005, and future projections of the prevalence of adult obesity are needed by health policy-makers. In a secondary analysis of published data, a number of assumptions were applied to estimate the trends and projections in the age-and sex-specific prevalence of adult obesity in Saudi Arabia over the period 1992-2022. Five studies conducted between 1989 and 2005 were eligible for inclusion, using body mass index (BMI) ≥ 30 kg/m(2) to define obesity. The overall prevalence of obesity was projected to increase from around 12% in 1992 to 41% by 2022 in men, and from 21% to 78% in women. Women had much higher projected prevalence than men, particularly in the age groups 35-44, 45-54 and 55-64 years. Effective national strategies are needed to reduce or halt the projected rise in obesity prevalence.

    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.

Depending on the presence of Citrullus colocynthis L. species, seven stands on the West of Saudi Arabia; expending from 25 m up to 2220 m a.s.l. height and 330 km long were selected for this study. Soil samples were collected from the studied localities and the soil properties were investigated. Also, plant species associated with C. colocynthis were collected, recorded and prepared as herbarium specimens. The studied localities were represented by different ecological, geographical and edaphic sites. A list of 127 species belonging to 41 families present in all locations was recorded. Calotropis procera was the representative species with C. colocynthis in all localities. The percentage of presence of the associated species were different between species in each location and also from location to other. Three different ecological areas could be distinguished in the study area. The area near the red sea characterized by salty sandy soil and low vegetation represented the first area. The second one was the coastal plain and West slope which characterized by low rainfall and xerophytic plants. The third one was the mountainous area which characterized by high altitude, more rainfall and high density of vegetation.

    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.

    From March 2004 to February 2006, a mosquito survey was conducted in Makka Al Mukarrama Region, in the western part of Saudi Arabia, and 19 species which belong to 4 genera, were collected: Aedes (2 species), Anopheles (8 species), Culex (8 species) and Culiseta (1 species). The mosquitoes were Aedes caspius, Ae. aegypti, Anopheles d'thali, An. gambiae, An. multicolor, An. rhodesiensis, An. sergenti, An. stephensi, An. subpictus, An. turkhudi, Culex arbieeni, Cx. laticinctus, Cx. pipiens, Cx. quinquefasciatus, Cx. sinaiticus, Cx. tigripes, Cx. tritaeniorhynchus, Cx. univittatus and Culiseta longiareolata. Cx. arbieeni was reported for the first time in Saudi Arabia from Al Taif District. The physical properties of water of mosquito's larval breeding sites showed the total dissolved salts (TDS) varied between 70-15552 ppm, pH ranged between 5.4-11.2 and water temperature varied between 15 degrees C in winter to 40.7 degrees C in summer. There was no correlation between these physical properties and the distribution of mosquito larvae. Light traps collected 1858 mosquitoes, and adult Culex were the most prevalent as 1658 (89.24%) were collected, followed by 121 (6.51%) Aedes, 68 (3.66%) Anopheles and 11 (0.59%) Culiseta. The effects of temperature and rainfall on seasonal abundance of mosquitoes in the study area are discussed.

    The introduction of the World Wide Web has revolutionized the applications of the computer and the Internet in the medical field. The Web provides an easy and cost-effective way of retrieving medical information and a more flexible way of communicating with patients and colleagues. Family practice is a specialty in which care is given to persons as individuals and members of families regardless of their age, gender or specific problems. To provide quality family practice, a family physician should be a good communicator, a critical thinker, a resource and information manager, a life-long learner, a care giver and a community advocate. Providing such high quality care requires that family practice be an information-sensitive specialty. However, the expansion of the new electronic resources on the Internet and the Web poses a real challenge to the family physician. Family physician in Saudi Arabia need to have basic skills and knowledge for easily retrieving and finding reliable Internet information for his professional development and the care of his patients. This article addresses the Web applications for family physicians in Saudi Arabia, giving examples of the most important Websites. PMID:23008644

    A large proportion of child physical abuse cases go undocumented and unreported. Dentists can play an important role in identifying and reporting these cases, but little has been reported about this issue in Saudi Arabia. The aims of the study were to (1) assess dentists' knowledge of child physical abuse, (2) assess dentists' attitudes towards child physical abuse, and (3) assess the behaviors of dentists in identifying and reporting child physical abuse. A cross-sectional survey of pediatric dentists, pediatric dentistry residents, and dental interns practicing at all of the dental schools in Jeddah, Saudi Arabia was conducted using an anonymous, self-administered questionnaire. The participants in current study demonstrated insufficient knowledge of the signs and symptoms of child physical abuse, actions that should be taken in suspected cases, circumstances in which to report such cases, and the legal authorities to which they should be reported. The attitudes of participants towards detecting and reporting cases were generally positive. Only 11% of the participants had suspected a case of child abuse, and only 3% of them reported it. Lack of knowledge about referral procedures and fear of anger from family members were the main causes of underreporting. In conclusion, this study showed that dentists have insufficient knowledge about child physical abuse but positive attitudes towards their role in detecting and reporting it. This topic should be covered and emphasized in dental schools' curricula, and healthcare and academic institutes must have a clear protocol to be followed if a case of abuse is suspected.

    The purpose of this study is to assess the knowledge, attitudes, and practice patterns of urologists in Saudi Arabia regarding prevention of recurrent stone formation and how much they follow preventive stone disease management guidelines. A questionnaire about knowledge, attitudes, and practice patterns of urologists in Saudi Arabia regarding prevention of recurrent stone formation was used. The survey comprised three domains: knowledge, attitudes, and practice patterns. Data about gender, duration of experience and health care sector were also collected. Individual responses were recorded, tabulated and compared using descriptive statistics. The overall response rate was 38.8%. All respondents were male urologists. Most of them (62, 71.3%) had an experience of 5-20 years in management of stone disease patients and the majority (74, 85.1%) belonged to the governmental health care sector. A total of 51% of the respondents answered in concordance with the best practice guidelines in at least half of the questions and 40% in all of the questions. Overall, practice patterns of 58% of the respondents were in concordance with the best practice guidelines in all the questions except for the question of practices regarding stone analysis. As regards to attitude domain, a total of 58.7% respondents expressed their agreement or strong agreement with the questions. Urologists' knowledge of stone recurrence preventive programs is suboptimal. They do not apply effectively the best stone prevention practice guidelines in their daily practice as well. Efforts to increase knowledge and enforce its application in daily practice are strongly warranted.

    The bulk of the Arabian Shield of Saudi Arabia is underlain by Neoproterozoic terranes of oceanic affinity that were accreted during Pan-African time (about 680- 640Ma). Geologicalmappingandisotopicinvestigations during the 1980’s,however, provided the first evidence for Paleoproterozoic continental crust within the east- central part of the shield in Saudi Arabia. These studies delineated an older basement domain, herein referred to as the Khida terrane (Fig. l), which is defined as that part of the southern Afif composite terrane underlain by Paleoproterozoicto Archean continental crust (Stoeser and Stacey, 1988). The isotopic and geochronologic work to support our current studies within the Khida terrane are discussed in a companion abstract (Whitehouse et al., this volume). The regional geology and geochronology of the region has been summarized in detail by Johnson (1996). The current study is based on the continued use of samples previously collected in the Khida area by the authors and others as well as new field work conducted by us in 1999. This work further defines the occurrence of late Paleoproterozoic rocks at Jabal Muhayil, which is located at the eastern margin of the exposed terrane (Fig. 1). Our isotopic work is at an early stage and this abstract partly relates geologic problems that remain to be resolved.

    Objectives To assess the dental health knowledge and the interest of secondary school teachers in imparting oral health education in Hail, Saudi Arabia Methods It was a questionnaire based cross-sectional survey of secondary school teachers in Hail, Saudi Arabia, carried out from November 2014 to January 2015. A validated self-administered questionnaire was used to determine teachers’ oral health knowledge and their interest in participating in oral health education of school children. Data analysis was performed using SPSS version 20 statistical software. Results Two hundred and twenty three secondary school teachers responded to the survey. Results showed that about 80 to 90 % of teachers had sufficient knowledge of causes and prevention of dental caries and gingivitis. About 94% of teachers agreed that they can play an effective role in oral health promotion while 96% were found to be interested in performing additional duty as oral health promoter. A large majority (91.9 %) had the opinion that oral health education must be included in school curriculum. Conclusion Teachers in Hail region had adequate amount of knowledge regarding oral health, and they were interested to play their role in promoting oral health education. Based on the findings of this study, it is recommended to include dental health education in curriculum at secondary school level and to provide sufficient training to teachers to enable them to participate actively in oral health promotion activities.

    Our aim was to evaluate end-of-life practices in a tertiary intensive care unit in Saudi Arabia. A prospective observational study was conducted in the medical-surgical intensive care unit of a teaching hospital in Riyadh, Saudi Arabia. Over the course of the one-year study period, 176 patients died and 77% of these deaths were preceded by end-of-life decisions. Of these, 66% made do-not-resuscitate decisions, 30% decided to withhold life support and 4% withdrew life support. These decisions were made after a median time of four days (Q1 to Q3: 1 to 9) and at least one day before death (Q1 to Q3: 1 to 4). The patients' families or surrogates were informed for 88% of the decisions and all decisions were documented in the patients' medical records. Despite religious and cultural values, more than three-quarters of the patients whose deaths were preceded by end-of-life decisions gave do-not-resuscitate decisions before death. These decisions should be made early in the patients' stay in the intensive care unit. PMID:22313074

    Pharmacoeconomics is a branch of health economics related to the most economical and efficient use of pharmaceuticals. Pharmacoeconomic research identifies, measures and compares the costs and outcomes (clinical, economic and humanistic) of pharmaceutical products and services. Pharmacoeconomic evaluation can play a significant role in the efficient allocation of resources in healthcare systems with constrained budgets. Countries are trying to control the rising costs of health care in their aging population. They are all asking the same question: Is the new drug good value for money; and if so, what is the society willing to pay for it? This article reviews the importance of, and the need for, adaptation of pharmacoeconomic analysis to the conditions in Saudi Arabia. It will shed some light on the important steps for converting the concept into practice, including the need for identifying the willing-to-pay (WTP) or the threshold cutoff, the existence of a real cost for each utility, the nonexistence of an pharmacoeconomic advisory forum, pharmaceutical budget allocation, and the impact of pharmaceutical marketing. It will also provide recommendations for easing any challenges that might jeopardize the conduct of such analysis in Saudi Arabia. PMID:21808106

  16. Ecological significance of wood anatomy in two lianas from arid southwestern Saudi Arabia.

    PubMed

    Masrahi, Yahya S

    2014-09-01

    The hot and arid lowlands of southwestern Saudi Arabia are home to two common lianas, Cocculus pendulus and Leptadenia arborea. This paper attempts to relate the adaptation of these two climbing woody perennials to such a harsh environment to the anatomy and hydraulic characteristics of their wood. The stems of these lianas have wood with wide xylem vessels and high hydraulic conductivity which should enhance water flow to the upper canopy despite their severe twisting. Hydraulic conductivity is further helped by the simple perforation plates of xylem vessels. The circular thickening of xylem walls gives them strength and reduces the risk of their collapse and the ensuing embolism in the advent of high tension created by severe water deficit and high evapo-transpiration demand. Wide vessels, on the other hand, are more susceptible to embolism. This problem may be overcome by reducing the solute potential of xylem sap by hydrolysis of starch grains which were found to be abundant in the vicinity of the vessels. This should help absorb water by the deep roots from the capillary fringes of the typically shallow water table in this particular habitat. Furthermore, the abundance of ray parenchyma cells between xylem groups of both lianas provides great flexibility with minimum damage to water conduits in the stem during climbing and twisted growth. It was concluded that these wood features in both lianas are crucial for survival under the harsh conditions of arid Tihama plains of southwestern Saudi Arabia. PMID:25183944

    An indoor radon survey was carried out recently in nine cities of Saudi Arabia using nuclear track detectors (NTD)-based passive radon detectors. The survey included Qatif City in the Eastern Province of Saudi Arabia, where 225 detectors were collected back successfully. It was found that the average indoor radon concentration in the dwellings was 22 +/- 15 Bq m(-3). However, one of the dwellings showed an anomalous radon concentration of 535 +/- 23 Bq m(-3). This finding led to a detailed investigation of this dwelling using active and passive techniques. In the active technique, an AlphaGUARD 2000 PRQ radon gas analyser was used. In the passive technique, CR-39 based passive radon detectors were used in all the rooms of the dwelling. Radon exhalation from the wall and the floor was also measured using the can technique. The active measurement confirms the passive one. Before placing the passive radon detectors in all the rooms of the two-storey building, the inhabitant was advised to ventilate his house regularly. The radon concentration in the different rooms was found to vary from 124 to 302 Bq m(-3). Radon exhalation from the floor and the wall of the room with the anomalous radon concentration was found to vary from 0.5 to 0.8 Bq m(-2) h(-1). These low radon exhalation rates suggest that the anomalous radon concentration is most probably due to underground radon diffusion into the dwelling through cracks and joints in the concrete floor.

    Background.  UpToDate is an online clinical decision support resource that is used extensively by clinicians around the world. Digital surveillance techniques have shown promise to aid with the detection and monitoring of infectious disease outbreaks. We sought to determine whether UpToDate searches for Middle East respiratory syndrome (MERS) could be used to detect and monitor MERS outbreaks in Saudi Arabia. Methods.  We analyzed daily searches related to MERS in Jeddah and Riyadh, Saudi Arabia during 3 outbreaks in these cities in 2014 and 2015 and compared them with reported cases during the same periods. We also compared UpToDate MERS searches in the affected cities to those in a composite of 4 negative control cities for the 2 outbreaks in 2014. Results.  UpToDate MERS searches during all 3 MERS outbreaks in Saudi Arabia showed a correlation to reported cases. In addition, UpToDate MERS search volume in Jeddah and Riyadh during the outbreak periods in 2014 was significantly higher than the concurrent search volume in the 4 negative control cities. In contrast, during the baseline periods, there was no difference between UpToDate searches for MERS in the affected cities compared with the negative control cities. Conclusions.  UpToDate search activity seems to be useful for detecting and monitoring outbreaks of MERS in Saudi Arabia.

    [Purpose] To explore the views of the physical therapy service leaders in Saudi Arabia regarding the integration of physical therapy service in primary health care settings. [Subjects and Methods] A self-administered questionnaire consisting of both open and closed ended questions was distributed during May-July 2013 via email to physical therapy leaders representing different regions and health care providers in Saudi Arabia. [Results] Twenty-six participants answered the questionnaire. Eighty five percent of the sample had ≥ 10 years of experience with 57.6% of them holding a post-graduate degree. Participants were from different health care providers and represented different geographical regions of Saudi Arabia. Eighty one percent of the sample reported that the adoption of physical therapy services in primary health care would be advantageous, as it would offer earlier access to health care and would be more cost-effective. The respondents also stated that such a service would contribute towards the prevention of common non-communicable health diseases. [Conclusion] The results of this survey provide generally positive recommendations for the provision of physical therapy service in Saudi Arabia primary health care centers. However, challenges and barriers identified by this study require consideration during the development of the service.

The region of Riyadh, Saudi Arabia had the highest overall age-standardized incidence rate (ASIR) at 7.8, followed by the Eastern region at 6.8, and Makkah at 6.1 per 100,000 men; however, Jazan, Hail, and Baha had the lowest average ASIRs at 2.5, 3.7, and 3.9 per 100,000 men, respectively. The incidence-rate ratio for the number of NHL cases was significantly higher in Riyadh (4.68, 95% confidence interval [CI] 4.11–5.32), followed by Makkah (4.47, 95% CI 3.94–5.07), and the Eastern region of Saudi Arabia (3.27, 95% CI 2.90–3.69) than that in the reference region of Jazan. Jouf had the highest changes in the ASIRs of NHL among Saudi men from 2001 and 2008 (5.0 per 100,000 men). Conclusion A significant increase in the crude incidence rate and ASIR for NHL in Saudi Arabia between 2001 and 2008 was found. Riyadh, the Eastern region, and Makkah had the highest overall ASIR in Saudi Arabia. Jazan, Hail, and Baha had the lowest rates. Additionally, Riyadh, Makkah, and the Eastern region had the highest incidence-rate ratio for the number of NHL cases. Finally, Jouf had the highest changes in crude incidence rate and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of NHL among Saudi men.

    As an aspect of the changing climatic conditions and anthropogenic impact; however, floods and torrents have been recently existed in Jeddah, the coastal Saudi city along the Red Sea. Distributed over 28 surface water basins, totaling an area of more than 2500km2, floods cover more than 15% of the area. This is well pronounced in 2009 and 2011, and it was attributed mainly to the torrential rainfall peaks the area witnesses lately. In addition, there is a chaotic urban distribution from the coastal zone to the adjacent mountain chains to the east, where torrential water runs towards the coast. A detailed assessment has been obtained using advanced space tools (e.g. high-resolution satellite images), and the application was carried out on several aspects of these images and at different dates. This was accomplished in combination the applications of geo-spatial systems to induce the mechanism of water flow regime and to identify the major reasons behind the high risk magnitude. Consequently, the geomorphologic and hydrologic parameters for flood occurrence were recognized. In the light of this catastrophic status; however, mitigation measures are rare enough to protect the area under risk. Recently, and after the 2009 and the recurrent 2011 disasters, which were resulted from floods, some mitigation measures have been undertaken and others were proposed. However, there is still uncertainty for an integrated flood control system. This can be viewed from the unsuitability of the selected sites and erroneous applications for flood controls. Besides, there is a lack to: 1) a giant channeling system for the risk area, 2) check dams, 3) ponds for water collection, 4) sediments-fixing controls, 5) traced watercourses. This is in addition to absence of proper legislation to prevent chaotic urban activities along valleys' pathways.

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

    The apical membrane antigen 1 of Plasmodium falciparum (PfAMA1) plays a crucial role in erythrocyte invasion and is a target of protective antibodies. Although domain I of PfAMA1 has been considered a promising vaccine component, extensive sequence diversity in this domain could compromise an effective vaccine design. To explore the extent of sequence diversity in domain I of PfAMA1, P. falciparum-infected blood samples from Saudi Arabia collected between 2007 and 2009 were analyzed and compared with those from worldwide parasite populations. Forty-six haplotypes and a novel codon change (M190V) were found among Saudi Arabian isolates. The haplotype diversity (0.948±0.004) and nucleotide diversity (0.0191±0.0008) were comparable to those from African hyperendemic countries. Positive selection in domain I of PfAMA1 among Saudi Arabian parasite population was observed because nonsynonymous nucleotide substitutions per nonsynonymous site (dN) significantly exceeded synonymous nucleotide substitutions per synonymous site (dS) and Tajima's D and its related statistics significantly deviated from neutrality in the positive direction. Despite a relatively low prevalence of malaria in Saudi Arabia, a minimum of 17 recombination events occurred in domain I. Genetic differentiation was significant between P. falciparum in Saudi Arabia and parasites from other geographic origins. Several shared or closely related haplotypes were found among parasites from different geographic areas, suggesting that vaccine derived from multiple shared epitopes could be effective across endemic countries.

    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.

    Introduction Syphilis is one of the known transfusion-transmissible infections and causes 100,000 deaths yearly, with around 90% of these deaths occurring in the developing world. Little data is available regarding the prevalence of syphilis among Saudi blood and stem cell donors. We conducted a survey on the incidence of syphilis among all blood and stem cell donors. Methods This study was conducted at the Prince Sultan Military Medical City in Riyadh, Saudi Arabia in the 10 years period data during 2006–2015. Data were analyzed about full history, physical examination, age, sex, weight, profession, marital status, number of the donations, data of last donation, having a relation who received blood transfusion, as well as the screening test results of the donated blood. We determined the seroprevalence of infection and compared by sex and other variable through frequency analysis, Chi square, Fisher, and prevalence ratios. Results Approximately 240,000 blood donors were screened and studied in the period of study. Most of the blood donors were male (98.3%) and 89% of them were citizens of Saudi Arabia. According to our findings, we estimated that, in the last 10 years, approximately 0.044% of all the blood donors were syphilis positive cases. No cases were detected as positive for syphilis among stem cell donors. Only 60 blood donors tested positive for syphilis. In addition, we studied 202 stem cell transplant donors during the same period, of which 59% were male and none texted positive for syphilis. Conclusions A concerted effort between the government, health care providers, regulatory bodies and accreditation agencies have all contributed in eliminating the risk of spreading syphilis among blood donors.

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

    [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. PMID:25995567

    BACKGROUND: Respiratory care (RC) is an allied health profession that involves assessing and treating patients who have pulmonary diseases. Research indicates that respiratory therapists’ (RT's) involvement in caring for patients with respiratory disorders improves important outcome measures. In Kingdome of Saudi Arabia (KSA), RC has been practiced by RTs for more than 30 years. OBJECTIVE: We sought to investigate the status of the RC workforce in Saudi Arabia in terms of demographic distribution, number, education, and RC service coverage. METHODS: We used a specially designed survey to collect data. A list of 411 working hospitals in KSA was obtained. All hospitals were contacted to inquire if RC is practiced by RTs. Data were collected from hospitals that employ RTs. RESULTS: Only 88 hospitals, 21.4% of total hospitals in the country, have RTs. Out of the 244 Ministry of Health (MOH) hospitals, only 31 hospitals (12.7%) employ RTs. There are 1,477 active RTs in KSA. Twenty-five percent of them, or 371, are Saudis. The majority of the RT workforce (60%) work for non-MOH government hospitals, and almost half the total RTs work in Riyadh province. About 60% of RTs work in critical care settings. RC coverage of critical care was 44.5% of ideal. The overall RT-to-ICU bed ratio was 1:11. The ratio was 1:9 for non-MOH government hospitals, and 1:20 for MOH hospitals. CONCLUSIONS: We report the first insightful data on RC workforce in KSA. These data should be used by educational institutions and health policy makers to plan better RC coverage in the country.

    CONTEXT: Respiratory physiotherapy plays a key role in the management and treatment of patients with respiratory diseases worldwide, yet this specialty is not well established in Saudi Arabia. AIMS: To profile the attitudes among physicians and nurses toward physiotherapists working in respiratory care settings in Saudi Arabia. METHODS: A cross-sectional questionnaire-based study was conducted. A questionnaire was developed consisting of 23 items, which was distributed both electronically and in paper form to physicians and nurses working in hospitals and health-care centers in Saudi Arabia. Physicians and nurses working outside of Saudi Arabia, and other health professionals, were excluded from the study. RESULTS: A total of 284 questionnaires were returned (nurses: n = 158; physicians: n = 126). The majority believed that physiotherapists have the skills to be involved in respiratory care (79.9%, n = 226) and that physiotherapists are an important member of the Intensive Care Unit team (90.4%, n = 255). Most respondents (n = 232, 82.9%) felt in need of more information regarding the role of physiotherapy within respiratory care; significantly more nurses than physicians believed they needed additional education (P = 0.002). Specialized physicians were more likely than nonspecialized physicians to refer respiratory patients to physiotherapy (P < 0.05). CONCLUSION: Physiotherapy in respiratory care settings was positively regarded by nurses and physicians working in hospitals and health-care facilities in Saudi Arabia. The need for further education for physicians and nurses on the role of physiotherapy in respiratory care was highlighted; this would enable physiotherapy to develop and be further integrated into the respiratory care multidisciplinary team.

    Saudi Arabia has a rich architectural heritage that can be found in all regions of the vast country. Except for a small number of publications the recording and documentation of the traditional built environment was not content of detailed scientific investigations so far. But with the increasing decay of the architectural heritage the interest for this kind of research is rising. A mirror of this efforts is the National Built Heritage Forum, annual conference, launched in 2010 by his excellency Prince Sultan bin Salman bin Abdulaziz Al Saud and the Saudi Commission for Tourism and Antiquities (SCTA). In that frame Saudi universities are intensifying research and educational programs for the research of traditional architecture. In 2008 the Department of Architecture of the College of Environmental Design at the King Abdulaziz University established a cooperation with the Department of History of Architecture and Building Archaeology of the Vienna University of Technology with the aim to start an exchange of knowledge and experience in building archaeology and building survey. An important part of this cooperation was a workshop for staff and students in the historic centre of Jeddah. The aim was to train methods and techniques on typical examples in the old town of Jeddah, Al Balad. This paper is describing the layout of the workshop, the process of the work and examples of the results.

    This study explores identity motives for using a microblogging site (Twitter) among Internet users in Saudi Arabia and the UK. The former boasts the world's highest per capita use of Twitter, which provides a forum in which users have more opportunity for self-expression than they do in the offline world, and is not subject to the heavy censorship which the Saudi government imposes on other Internet content [1]. Approximately 5000 tweets from the period April-May 2013 were coded and analyzed, using Motivated Identity Construction Theory as a conceptual framework [2]. This theory proposes six universal identity motives of meaning, belonging, continuity, distinctiveness, efficacy, and self-esteem. We consider these motives in turn, and examine their relative prominence in an online context. Support was found for all six universal motives, but the relative prominence of motives and the ways in which they were pursued appeared to depend on the affordances of both the OSN in question, Twitter and the cultural context in which the user was posting: Saudi users appeared to seek distinctiveness, whereas for British users, belonging was a more salient motive. Themes related to meaning, efficacy, and self-esteem were detected frequently, whereas themes related to continuity were less apparent. PMID:24875705

    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.

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

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

    White spot syndrome virus (WSSV) and Taura syndrome virus (TSV) are highly pathogenic to penaeid shrimp and have caused significant economic losses in the shrimp culture industry around the world. During 2010 and 2011, both WSSV and TSV were found in Saudi Arabia, where they caused severe mortalities in cultured Indian white shrimp Penaeus indicus. Most outbreaks of shrimp viruses in production facilities can be traced to the importation of infected stocks or commodity shrimp. In an attempt to determine the origins of these viral outbreaks in Saudi Arabia, we performed variable number of tandem repeat (VNTR) analyses for WSSV isolates and a phylogenetic analysis for TSV isolates. From the WSSV genome, the VNTR in open reading frames (ORFs) 125 and 94 were investigated with PCR followed by DNA sequence analysis. The genotypes were categorized as {N125, N94} where N is the number of repeat units in a specific ORF, and the subscript indicates the ORF (i.e. ORFs 125 and 94 in this case). From 15 Saudi Arabia WSSV isolates, we detected 3 genotypes: {6125, 794}, {7125, del94}, and {8125, 1394}. The WSSV genotype of {7125, del94} appears to be a new variant with a 1522 bp deletion encompassing complete coding regions of ORF 94 and ORF 95 and the first 82 bp of ORF 93. For TSV genotyping, we used a phylogenetic analysis based on the amino acid sequence of TSV capsid protein 2 (CP2). We analyzed 8 Saudi Arabian isolates in addition to 36 isolates from other areas: SE Asia, Mexico, Venezuela and Belize. The Saudi Arabian TSV clustered into a new, distinct group. Based on these genotyping analyses, new WSSV and TSV genotypes were found in Saudi Arabia. The data suggest that they have come from wild shrimp Penaeus indicus from the Red Sea that are used for broodstock. PMID:22832716

    In the public schools of many developing countries, numerous accidents and incidents occur because of poor safety regulations and management systems. To improve the educational environment in Saudi Arabia, the Ministry of Education seeks novel approaches to measure school safety performance in order to decrease incidents and accidents. The main objective of this research was to develop a systematic approach for measuring Saudi school safety performance using the balanced scorecard framework philosophy. The evolved third generation balanced scorecard framework is considered to be a suitable and robust framework that captures the system-wide leading and lagging indicators of business performance. The balanced scorecard architecture is ideal for adaptation to complex areas such as safety management where a holistic system evaluation is more effective than traditional compartmentalised approaches. In developing the safety performance balanced scorecard for Saudi schools, the conceptual framework was first developed and peer-reviewed by eighteen Saudi education experts. Next, 200 participants, including teachers, school executives, and Ministry of Education officers, were recruited to rate both the importance and the performance of 79 measurement items used in the framework. Exploratory factor analysis, followed by the confirmatory partial least squares method, was then conducted in order to operationalise the safety performance balanced scorecard, which encapsulates the following five salient perspectives: safety management and leadership; safety learning and training; safety policy, procedures and processes; workforce safety culture; and safety performance. Partial least squares based structural equation modelling was then conducted to reveal five significant relationships between perspectives, namely, safety management and leadership had a significant effect on safety learning and training and safety policy, procedures and processes, both safety learning and training

    BACKGROUND AND OBJECTIVE: The WHO recommends exclusive breastfeeding in the first 6 months of life. Our objective was to evaluate trends in infant nutrition in Saudi Arabia and the degree of compliance with WHO recommendations. SUBJECTS AND METHODS: A nationwide nutritional survey of a sample of Saudi households was selected by the multistage probability sampling procedure. A validated questionnaire was administered to mothers of children less than 3 years of age. RESULTS: Of 5339 children in the sample, 4889 received breast milk at birth indicating a prevalence of initiation of 91.6%. Initiation of breastfeeding was delayed beyond 6 hours after birth in 28.1% of the infants. Bottle feeding was introduced by 1 month of age to 2174/4260 (51.4%) and to 3831/4260 (90%) by 6 months of age. The majority of infants 3870/4787 (80.8%) were introduced to “solid foods” between 4 to 6 months of age and whole milk feedings were given to 40% of children younger than 12 months of age. CONCLUSIONS: The current practice of feeding of Saudi infants is very far from compliance with even the most conservative WHO recommendations of exclusive breastfeeding for 4 to 6 months. The high prevalence of breastfeeding initiation at birth indicates the willingness of Saudi mothers to breastfeed. However, early introduction of complementary feedings reduced the period of exclusive breastfeeding. Research in infant nutrition should be a public health priority to improve the rate of breastfeeding and to minimize other inappropriate practices. PMID:19139623

    Aim: The aim of this study was to demonstrate the genomic features of Meq gene of Marek’s disease virus (MDV) recently circulating in Saudi Arabia (SA). Materials and Methods: Two poultry flocks suffering from mortalities and visceral tumors were presented to the Veterinary Teaching Hospital, King Faisal University, SA. Subjected to different diagnostic procedures: Case history, clinical signs, and necropsy as well as polymerase chain reaction followed by Meq gene sequence analysis. Results: Case history, clinical signs, and necropsy were suggestive of MDV infection. The Meq gene was successfully detected in liver and spleen of infected chickens. A 1062 bp band including the native Meq ORF in addition to a 939 bp of S-Meq (short isoform of Meq) were amplified from Saudi 01-13 and Saudi 02-13, respectively. The nucleotide and deduced amino acids sequences of the amplified Meq genes of both Saudi isolates showed distinct polymorphism when compared with the standard USA virulent isolates Md5 and GA. The sequence analysis of the S-Meq gene showed a 123 bp deletion representing 41 amino acids between two proline-rich areas without any frameshift. The Meq gene encoded four repeats of proline-rich repeats (PRRs sequences), whereas the S-Meq contains only two PRRs. Interestingly, the phylogenetic analysis revealed that both of SA MDV isolates are closely related to the MDV strains from Poland. Conclusion: The two MDV isolates contain several nucleotide polymorphisms resulting in distinct amino acid substitutions. It is suggested that migratory and wild birds, as well as world trading of poultry and its by-products, have a great contribution in the transmission of MDVs overseas. PMID:27397979

    In the public schools of many developing countries, numerous accidents and incidents occur because of poor safety regulations and management systems. To improve the educational environment in Saudi Arabia, the Ministry of Education seeks novel approaches to measure school safety performance in order to decrease incidents and accidents. The main objective of this research was to develop a systematic approach for measuring Saudi school safety performance using the balanced scorecard framework philosophy. The evolved third generation balanced scorecard framework is considered to be a suitable and robust framework that captures the system-wide leading and lagging indicators of business performance. The balanced scorecard architecture is ideal for adaptation to complex areas such as safety management where a holistic system evaluation is more effective than traditional compartmentalised approaches. In developing the safety performance balanced scorecard for Saudi schools, the conceptual framework was first developed and peer-reviewed by eighteen Saudi education experts. Next, 200 participants, including teachers, school executives, and Ministry of Education officers, were recruited to rate both the importance and the performance of 79 measurement items used in the framework. Exploratory factor analysis, followed by the confirmatory partial least squares method, was then conducted in order to operationalise the safety performance balanced scorecard, which encapsulates the following five salient perspectives: safety management and leadership; safety learning and training; safety policy, procedures and processes; workforce safety culture; and safety performance. Partial least squares based structural equation modelling was then conducted to reveal five significant relationships between perspectives, namely, safety management and leadership had a significant effect on safety learning and training and safety policy, procedures and processes, both safety learning and training

    This retrospective study aimed to collect data related to the clinical manifestations and laboratory investigations of systemic lupus erythematosus (SLE) patients in the eastern part of Saudi Arabia, in one of the tertiary-care centers, King Fahd Hospital Al-Hasa, and to compare it with other regions of Saudi Arabia. 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.

    Background The aim of this work was to describe the indications, complications, and outcomes of penetrating keratoplasty (PKP) in Saudi Arabia. Methods In a retrospective, noncomparative interventional case series, the medical records of patients who underwent PKP from January 2000 to December 2008 and had a minimum follow-up of 6 months were reviewed. All corneas were obtained from eye banks in the US. Indications, complications, and outcomes of surgery were recorded. This study was approved by the institutional review board. Results Eighty-five consecutive eyes were included in this study. There were 52 (61.2%) males and 33 (38.8%) females. The median age was 35.0 years (range 3–85 years), and the median follow-up period was 24 months (range 6–108 months). The indications for PKP were keratoconus, bullous keratopathy, corneal scars, corneal dystrophy, and corneal regraft. The overall graft survival time was 88.9 months ± 4.9 months (mean ± standard error of mean, 95% confidence interval [CI] 79.4 months –98.4 months) while the 3-year and 5-year cumulative survival rates were 90.7% and 84.3%, respectively. Surgical indication (P = 0.038), immune rejection (P < 0.001), preoperative corneal vascularization (P = 0.022), and perioperative high intraocular pressure (P = 0.032) were associated significantly with corneal graft failure in univariate analysis. Multivariate analysis reduced these significant associations to rejection (P < 0.001) and vascularization (P = 0.009). Relative risk for failure in rejected cornea was 16.22 (95% CI 4.99–52.69) and in vascularized cornea was 3.89 (95% CI 1.36–11.09). At last visit following PKP, 34 (40%) eyes had best spectacle-corrected visual acuity of 20/40 or better, and 51 (60.0%) eyes had 20/80 or better. Best spectacle-corrected visual acuity was worse than 20/400 in 15 (17.6%) eyes. Conclusion The overall corneal graft survival in a private setting in Saudi Arabia can be excellent.

    In Saudi Arabia, the utilization of the world wide web has become increasingly popular. However, the exact figure of such use is unknown. This study aimed to determine the percentage of, and experience with, online Arabic drug information by Arabic-speaking adults in Saudi Arabia. A web based questionnaire was used. The questionnaire language was Arabic. Public were invited to participate in the survey through e-mails, Twitter, WhatsApp and Facebook in March 2012. The survey included 17 items examining the types of accessed Arabic drug information, the respondent's demographics, their ability to easily find and understand Arabic drug-related information, and their trustfulness and dependency on such information websites. Of the 422 Arabic speaking adults who answered the questionnaire, 88% stated that they used Arabic websites to answer drug-related questions. Of the respondents, 50% had a bachelor's degree, 44% were young adults, over half were female (60%), and 72% of them have a chronic disease. The ease of retrieving online information was the most common reason (69%) for consulting such websites. Google as a search engine was the most frequently (86%) accessible website. Although respondents reported different drug-related topics in their online searching, the search for adverse effects was the most common (68%). Respondents claimed that they could easily find (65%) and understand (49%) the drug-related information. Although a good number of respondents qualified this type of information as good, double-checking of information on other websites was highly recommended. Trustfulness was one of the important parameters to measure and 205 respondents (55%) claimed that they only trusted half of the information cited. Moreover, around 48% of respondents considered that finding the same information on more than one website increased its trustfulness. Surprisingly, 54% of respondents did not depend on Arabic information websites when making decisions on drug use

    There is an increasing trend towards consumption of complementary and alternative herbal products in many parts of the world. A cross-sectional sample of 115 community pharmacists in Riyadh, Saudi Arabia was visited and information on knowledge, attitudes and practices towards herbal remedies was collected using a structured questionnaire. All pharmacists acknowledged dispensing herbal products through their pharmacies. Ginseng was the most widely used product (47%), followed by ginkgo (23%), valerian (17%) and S.t John's wort (3.5%). In general, pharmacists had poor awareness about potential herb-drug interactions. While 56% of participating pharmacists expressed concerns about the safety of herbal remedies, 30% considered them to be harmless. Community pharmacists need to be better informed about herbal products. PMID:21218728

    A mineral reconnaissance of the Jabal Sahah quadrangle, Kingdom of Saudi Arabia, showed the presence of the anomalous elements silver, beryllium, molybdenum, niobium, tin, and tungsten and of anomalous amounts of chromium, nickel, lead, titanium, and vanadium. All anomalies are low except one for tin and one for tungsten in the granitic plug west of Jabal Sahah. Debris from this small plug contains as much as 1,000 ppm (parts per million) tin in wadi sand, and a concentrate from the sand contains as much as 40 ppm molybdenum and 1,000 ppm tungsten. The area of this small plug and the metamorphic rock around the plug should be studied in detail to learn distribution and value of tin, tungsten, niobium, and molybdenum in the rocks. Alkalic granite at Jabal Sahah contains beryllium,-molybdenum, tin, niobium, tungsten, and a low anomaly of lead.

    Risk factors for primary Middle East respiratory syndrome coronavirus (MERS-CoV) illness in humans are incompletely understood. We identified all primary MERS-CoV cases reported in Saudi Arabia during March–November 2014 by excluding those with history of exposure to other cases of MERS-CoV or acute respiratory illness of unknown cause or exposure to healthcare settings within 14 days before illness onset. Using a case–control design, we assessed differences in underlying medical conditions and environmental exposures among primary case-patients and 2–4 controls matched by age, sex, and neighborhood. Using multivariable analysis, we found that direct exposure to dromedary camels during the 2 weeks before illness onset, as well as diabetes mellitus, heart disease, and smoking, were each independently associated with MERS-CoV illness. Further investigation is needed to better understand animal-to-human transmission of MERS-CoV. PMID:26692185

    Mangrove sediments were collected from major mangrove stands on the Red Sea Coast of Saudi Arabia. Forty five isolates belonging to 12 genera were purified and five isolates as well as their consortium were found to be able to grow in association with petroleum oil as sole carbon source under in vitro conditions. The isolated strains were identified based on internal transcribed spacer (ITS) rDNA sequence analysis. The fungal strains with the greatest potentiality to degrade diesel oil, without developing antagonistic activity, were identified as Alternaria alternata, Aspergillus terreus, Cladosporium sphaerospermum, Eupenicillium hirayamae and Paecilomyces variotii. As compared to the controls, these fungi accumulated significantly higher biomass, produced extracellular enzymes and liberated larger volumes of CO2. These observations with GC-MS data confirm that these isolates displayed rapid diesel oil bioremoval and when used together as a consortium, there was no antagonistic activity. PMID:26981002

    The Jabal Khatam quadrangle encompasses an area of about 2,725 km2 on the edge of the Precambrian shield in northwestern Saudi Arabia, between lat 26°00' and 26°30' N. and long 39°30' and 40°00' E. The southern one-third and northeastern corner of the area are covered by Tertiary and Quaternary basalt flows of Harrat Khaybar and Harrat Ithnayn. In one small area on its northern edge, Harrat Khaybar is composed of Tertiary rhyolitic tuff and trachyte. Most of the northern one-third and eastern part of the quadrangle are covered by Paleozoic Siq Sandstone. The remainder of the quadrangle is composed of trachyandesite flows, agglomerate, graywacke, and sparse marble of the Hulayfah group and intrusive rocks that range in composition from alkali-feldspar granite to diabase. No deposits with economic potential were found. However, the geothermal potential of the quadrangle warrants further investigation.

    Invasive species are capable of causing considerable damage to natural ecosystems, agriculture and economies throughout the World. Samsum ant, Brachyponera (Pachycondyla) sennaarensis has been a reason for medical implication and social nuisance through its poisonous and severely painful sting causing anaphylactic shock in many cases. We surveyed for the presence of the samsum ant in various provinces of Saudi Arabia. B. sennaarensis was the abundant Ponerinae species in human settlements. In the Eastern provinces, however, few samples were collected, and none were found in the Northern and Western provinces. Infestations of B. sennaarensis were particularly severe in the spring and summer seasons, when the ants make nests in moist areas and in cracks in cemented structures, whereas the extent of infestation reduced in winter seasons.

    In order to document the microfacies and diagenesis of the reefal limestone in the uppermost part of the Callovian Tuwaiq Mountain Limestone Formation at Khashm Al-Qaddiyah area, central Saudi Arabia, scleractinian corals and rock samples were collected and thin sections were prepared. Coral framestone, coral floatstone, pelloidal packstone, bioclastic packstone, bioclastic wacke/packstone, algal wackestone and bioclastic foraminiferal wacke/packstone were the recorded microfacies types. Cementation, recrystallization, silicification and dolomitization are the main diagenetic alterations affected the aragonitic skeletons of scleractinian corals. All coral skeletons were recrystallized, while some ones were dolomitized and silicified. Microfacies types, as well as the fossil content of sclearctinian corals, bivalves, gastropods, brachiopods and foraminifera indicated a deposition in environments ranging from shelf lagoon with open circulation in quiet water below wave base to shallow reef flank and organic build up for the uppermost reefal part of the Tuwaiq Formation in the study area.

    Air quality assessment of the emission from power plant and traffic at Al-Taneem area located at the northern part of the Holy City of Makkah, Saudi Arabia, is investigated. Concentration levels of different pollutants including nitrogen dioxide (NO(2)), sulfur dioxide (SO(2)), carbon monoxide (CO), ozone (O(3)), methane (CH(4)) and total hydrocarbons (THC) as well as some meteorological parameters (temperature, wind speed and wind direction) during the period from November 2002 to October 2003 were measured and analyzed. The results indicated that nitrogen oxides and carbon monoxide concentrations increase at the starting hours of the day. Sulphur dioxide concentrations were relatively low and constant. Ozone concentration trend showed the changes of the rate of the photochemical reactions. The distribution of the measured concentrations may be used for the development of numerical models and the estimation of air quality parameters in urban environment.

    During a survey of demersal fishes of the southern Red Sea coast of Saudi Arabia off Jizan, 98 species were collected by trawling. Five of these represent new records for the Red Sea: Saurida longimanus, Dactyloptena gilberti, Jaydia novaeguineae, Pomadasys maculatus and Parapercis maculata. Additionally a specimen of the rare moray Gymnothorax reticularis, previously known from only three specimens, was collected. Records of two species, Parastromateus niger and Pseudorhombus arsius, that formerly were considered questionable, are confirmed by collection of new voucher specimens. Validity of Laeops sinusarabici is confirmed. This study documents parts of the diversity of the demersal fish communities on sandy areas of the southern Red Sea, but also emphasizes that a large proportion of this area has not been explored.

    Identifying potential groundwater recharge zones is a pre-requisite for any artificial recharge project. The present study focuses on identifying the potential zones of Artificial Groundwater Recharge (AGR) in Northwestern Saudi Arabia. Parameters including slope, soil texture, vadose zone thickness, groundwater quality (TDS) and type of water bearing formation were integrated in a GIS environment using Boolean logic. The results showed that 17.90% of the total studied area is suitable for AGR. The identified zones were integrated with the land use/land cover map to avoid agricultural and inhabited lands which reduced the total potential area to 14.24%. Geomorphologically the wadi beds are the most suitable sites for recharge. On the basis of the potential AGR zones closeness to the available recharge water supply (rain water, desalinated sea water and treated waste water) the potential zones were classified as Category A (high priority) and Category B (low priority).

    This study in Saudi Arabia explored the determinants of physicians' prescribing behaviour in primary care in Riyadh city. A self-administered questionnaire designed to explore factors influencing prescribing (sociodemographic factors; practice setting; continuing education; access to educational materials; pharmaceutical company representatives; and patient factors) was completed by 87 PHC physicians. A factor analysis of 56 variables extracted 7 factors that explained 46% of the variance. Of these, 4 components positively related to perceived good prescribing behaviour could be summarized as: clinical experience of physicians; use of educational materials for continuous updating of medical knowledge; enhanced levels of continuing medical education and willingness to involve patients in decision-making; and working as a team using pharmacists for consultation and emphasizing the role of medical education. The other 3 factors derived from the analysis were less easy to interpret and may have been statistical anomalies (or measurement errors). PMID:21735952

    Identifying the indicators of good quality medication prescribing assists physicians in preventing medication errors. This study in Riyadh city aimed to examine the relationship between physicians' self-reported influences on prescribing and the quality of their prescribing, defined as the completeness and accuracy of their prescription documentation. A sample of 600 randomly selected prescriptions written by 87 physicians were rated as high or low quality. The same physicians completed a questionnaire to determine the indicators of quality prescribing. The 7 components identified with factor loadings +0.5 or -0.5 were subjected to binary logistic regression modelling. While a range of potential quality indicators of drug prescribing were identified, none of the variables underpinning the 7components/factors survived the binary logistic regression mode. More studies are needed that take into account other quality indicators of medication prescribing in Saudi Arabia. PMID:21735953

    The Baid ad Jimalah tungsten deposit in Saudi Arabia consists predominantly of swarms of steeply dipping, subparallel, tungsten-bearing quartz veins and of less abundant, smaller stockwork veins. It is spatially, temporally, and genetically associated with a 569 Ma, highly differentiated, porphyritic, two-feldspar granite that intrudes Late Proterozoic immature sandstones. Baid al Jimalah is similar in character and origin to Phanerozoic tungsten-tin greisen deposits throughout the world, especially the Hemerdon deposit in Devon, England. It is also analogous to Climax-type molybdenum deposits, which contain virtually identical mineral assemblages, but with the relative proportions of molybdenum and tungsten mineralization reversed, primarily owing to differences in oxygen fugacity. This similarity in mineralization styles and fluid histories indicates that metallogenic processes in granite-related deposits in the late Precambrian were similar to those seen in the Phanerozoic. -from Authors

    During March–May 2014, a Middle East respiratory syndrome (MERS) outbreak occurred in Jeddah, Saudi Arabia, that included many persons who worked or received medical treatment at King Fahd General Hospital. We investigated 78 persons who had laboratory-confirmed MERS during March 2–May 10 and documented contact at this hospital. The 78 persons with MERS comprised 53 patients, 16 healthcare workers, and 9 visitors. Among the 53 patients, the most probable sites of acquisition were the emergency department (22 patients), inpatient areas (17), dialysis unit (11), and outpatient areas (3). Infection control deficiencies included limited separation of suspected MERS patients, patient crowding, and inconsistent use of infection control precautions; aggressive improvements in these deficiencies preceded a decline in cases. MERS coronavirus transmission probably was multifocal, occurring in multiple hospital settings. Continued vigilance and strict application of infection control precautions are necessary to prevent future MERS outbreaks. PMID:27089550

    The collaboration between the Research Center for Renewable Energy Mapping and Assessment (ReCREMA) at Masdar Institute of Science and Technology and the King Abdullah City for Atomic & Renewable Energy (KACARE) aims to create an interactive web tool integrated in the Renewable Resource Atlas where different solar thermal electricity (STE) utility-scale technologies will be simulated. In this paper, a methodology is presented for sizing and performance simulation of the solar field of parabolic trough collector (PTC) plants. The model is used for a case study analysis of the potential of STE in three sites located in the central, western, and eastern parts of Saudi Arabia. The plant located in the north (Tayma) has the lowest number of collectors with the best production along the year.

    The study describes the prevalence of different forms of smoking, and the correlates of current smoking, by male students of King Faisal University, Saudi Arabia. A random sample of 1382 students at 9 colleges answered a self-administered questionnaire based on the Global Youth Tobacco Survey plus the modified Fagerström Test for Nicotine Dependence. The prevalence of current smoking was 28.1% (21.6% for cigarettes, 14.6% for waterpipe). Of current smokers, 41.4% were living in homes where others smoke and 17.0% initiated smoking below age 12 years. In logistic regression analysis older age, living away from home, smoking by family and close friends and exposure to tobacco promotion were predictors of current smoking status.

    'Shamma', also known as Yemeni snuff, is frequently used as a chewing material in Yemen and some parts of Saudi Arabia. Preliminary clinical observations indicated that long-term users of 'shamma' may develop oral cancer. A battery of in vitro bioassays were, therefore, used to test genotoxicity of this substance. The test systems included the histidine reversion assay in Ames' Salmonella strains, induction of aberrant colonies and tryptophan gene conversion in the D7 diploid strain of Saccharomyces cerevisiae, and oncogenic transformation of C3H mouse embryo 10T1/2 cells. Data indicated that direct-acting mutagen(s) were present in a chloroform extract of the powdered 'shamma' resulting in positive effects in all of the test systems used. Using high-performance liquid chromatography (HPLC), three major fractions were separated from the extract, of which two were found to be mutagenic. PMID:3511366

    Antimicrobial resistance (AMR) is increasingly being highlighted as an urgent public and animal health issue worldwide. This issue is well demonstrated in bacteria that are resistant to last-line antibiotics, suggesting a future with untreatable infections. International agencies have suggested combating strategies against AMR. Saudi Arabia has several challenges that can stimulate the emergence and spread of multidrug-resistant bacteria. Tackling these challenges need efforts from multiple sectors to successfully control the spread and emergence of AMR in the country. Actions should include active surveillance to monitor the emergence and spread of AMR. Infection prevention and control precautions should also be optimized to limit further spread. Raising awareness is essential to limit inappropriate antibiotics use, and the antibiotic stewardship programs in hospital settings, outpatients, and community pharmacies, should regulate the ongoing use of antimicrobials.

    Abstract Five bee-fly species (Bombyliidae, Diptera) have been listed in this paper as new to the Kingdom of Saudi Arabia. Four of the recorded species have been identified to the level of species, namely: Bombomyia discoidea (Fabricius, 1794), Spogostylum candidum (Sack, 1909), Exoprosopa linearis Bezzi, 1924, and Exoprosopa minos (Meigen, 1804), while the fifth one only to genus, Desmatoneura sp. The species have been collected from Al-Baha and Asir Provinces in the south-western part of the Kingdom. One of the four identified species, Exoprosopa linearis, has an Afrotropical affinity, and another two, Spogostylum candidum and Bombomyia discoidea, have considerable Afrotropical distributions, and this result agrees to some extent with studies considering these parts of the Arabian Peninsula, including Al-Baha and Asir Provinces, having Afrotropical influences and may be included in the Afrotropical Region rather than in the Palaearctic Region or the Eremic zone.

    The Wadi Bidah district in southwest Saudi Arabia contains several ancient mines and mineral-prospects. The Precambian rocks of the district are steeply dipping and highly folded and faulted. They are divided into three major units: (1) older metavolcanic rocks, (2) metasedimentary rocks, and (3) younger metavolcanic rocks. Massive sulfide-type deposits show stratigraphic control and are found in metasedimentary rocks and in the younger metavolcanic rocks. There appears to be a close genetic relationship between the sulfide deposits and volcanism. Deposits containing copper, zinc, gold, and silver are indicated by geologic mapping and by shallow diamond drill holes in two of the ancient mine localities. The ore estimate for the district is 2.55 million short tons computed to depths that range from 79 to 150 meters. It seems probable that deeper drilling of the indicated deposits and drilling of other outlined target areas would add substantially to the ore reserves.

    Forty-five wildcats (Felis silvestris), 17 sand cats (Felis margarita), and 17 feral domestic cats were captured in central west Saudi Arabia, between May 1998 and April 2000, with the aim to assess their exposure to feline immunodeficiency virus/puma lentivirus (FIV/PLV), feline leukaemia virus (FeLV), feline herpesvirus (FHV-1), feline calicivirus (FCV), feline coronavirus (FCoV), and feline panleukopenia virus (FPLV). Serologic prevalence in wildcats, sand cats, and feral domestic cats were respectively: 6%, 0%, 8% for FIV/PLV; 3%, 8%, 0% for FeLV; 5%, 0%, 15% for FHV-1; 25%, 0%, 39% for FCV; 10%, 0%, 0% for FCoV; and 5%, 0%, 8% for FPLV. We recorded the first case of FeLV antigenemia in a wild sand cat. Positive results to FIV/PLV in wildcats and feral cats confirmed the occurrence of a feline lentivirus in the sampled population.

    Solar and wind data averages gathered for five years and plans for a 1.2-1.4 kW solar wind energy plant at Riyadh, Saudi Arabia are presented. Wind speeds were gathered at 2 m height averaging 3.9 m/sec, and extrapolated to 22 m and 5.45 m/sec; average solar intensity was found to be 600 W/sq m between 6 a.m. and 6 p.m. The generator system comprises a 5.5 m diameter multiblade windpowered turbine on a 10 meter tower and photovoltaic modules generating 500 W. The NACA 0018 blade tips will be enclosed within a conical duct, augmenting the wind velocity by an expected 10%. Lead-acid batteries will be used for storage; initial applications of the system are targeted for remote villages and military outposts.

    From September 1972 to January 1973, ERTS-1 precisely located a 500 sq km area on the Red Sea coastal plain of Saudi Arabia within which the Desert Locust (Schistocerca gregaria, Forsk.) bred successfully and produced many small swarms. Growth of vegetation shown by satellite imagery was confirmed from ground surveys and raingauge data. The experiment demonstrates the feasibility of detecting potential locust breeding sites by satellite, and shows that an operational satellite would be a powerful tool for routine survey of the 3 x 10 to the 7th power sq km invasion area of the Desert Locust in Africa and Asia, as well as of other locust species in the arid and semi-arid tropics.

    Three species of Pycnodus, a genus of extinct holostean fishes, have been identified from the Paleocene of Jabal Umm Himar, Harrat Hadan area, south-central Saudi Arabia, an area that was contiguous with Africa during the Early Tertiary. One of the species is larger than any species identified from the Early Tertiary of Africa. Its lower teeth are from 60 to 100 percent wider and 50 percent longer than those in P. mokattamensis, hitherto the largest species known from Africa. The second species, the most poorly represented of the three, is in dental size roughly 40 percent as large as the first species or about the same size as P. variabilis of Africa. The third species is small and, although the position of its teeth cannot be determined, this species clearly is distinct from the two other pycnodonts from Jabal Umm Himar.

    The Kingdom of Saudi Arabia is a major source of atmospheric dust. Frequent dust storms blow up and significantly affect human activities, airports and citizens' health. Aerosols optical and physical characteristics are influenced by major dust storms outbreaks. In this, paper, ground based AERONET measurements are integrated with space-borne sensors, namely MODIS and CALIPSO to analyze aerosols' characteristics during March - May of 2009 where a massive dust storm blew up and caused a widespread heavy atmospheric dust load over Saudi Arabia and the same period during 2010, where less dust activities were reported. The MODIS Deep Blue AOD analysis showed similar aerosols pattern over the land, however a substantial variance in aerosol loading during March - May 2009 compared with the same period in 2010 was observed. The angstrom exponent analysis showed that the majority of aerosol measurements in 2009 and 2010 are dominated by coarse-mode particles with angstrom exponent < 0.5. Detailed analysis of aerosol optical properties shows significant influence of coarse mode particles in the enhanced aerosol loading in 2009. The volume depolarization rations (VDR) derived from CALIPSO backscattering measurements is used to find latitudinal profile of mean aerosol optical depth to indicate the type of particles and to discriminate spherical aerosols with non-spherical particles.

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

    OBJECTIVE: Major sand storms are frequent in the Middle East. This study aims to investigate the role of air particulate matter (PM) level in acute asthma in children in Riyadh, Saudi Arabia. METHODS: An aerosol spectrometer was used to evaluate PM < 10μm in diameter (PM10) and PM < 2.5 μm in diameter (PM2.5) concentrations in the air every 30 minutes throughout February and March 2012 in Riyadh. Data on children 2-12 years of age presenting to the emergency department of a major children's hospital with acute asthma during the same period were collected including their acute asthma severity score. RESULTS: The median with interquartile range (IQR) levels of PM10 and PM2.5 were 454 μg/m3 (309,864) and 108 μg/m3 (72,192) respectively. There was no correlation between the average daily PM10 levels and the average number of children presenting with acute asthma per day (r = -0.14, P = 0.45), their daily asthma score (r = 0.014, P = 0.94), or admission rate ( r= -0.08, P = 0.65). This was also true for average daily PM2.5 levels. In addition, there was no difference in these variables between days with PM10 >1000 μg/m3, representing major sand storms, plus the following 5 days and other days with PM10< 1000 μg/m3. CONCLUSION: Sand storms, even major ones, had no significant impact on acute asthma exacerbations in children in Riyadh, Saudi Arabia. The very high levels of PM, however, deserve further studying especially of their long-term effects. PMID:25593604

    Objectives The Faculty of Dentistry at King Abdulaziz University (KAU) is planning to develop a master’s program in dental public health (DPH). To develop a curriculum for this program, a needs assessment was conducted in order to identify the level of DPH expertise that currently exists in Saudi Arabia, to identify gaps in knowledge, and to explore current perceptions regarding this type of program. Methods A competency-based survey instrument was administered to private and government affiliated dental practitioners in Jeddah, Saudi Arabia. Participants’ knowledge, attitudes, and competencies in DPH were assessed. In addition, questions were submitted that addressed preferred strategies of teaching, curriculum delivery methods, course content, and prerequisites for DPH. These data were combined with data previously collected from dentists holding academic positions at KAU (n = 146) and were analyzed using Statistical Analysis System version 9.3 software. Mean values and frequencies were calculated for the study variables. Proportional odds ratios and 95% confidence intervals were estimated to assess differences in educational preferences and DPH competencies according to age, gender, and qualification. Results Most of the participants (95%) reported a need for a DPH graduate program. The respondents had a basic knowledge of DPH and moderate experience in DPH competencies. A variety of preferred educational strategies and methods were identified and differences in educational preferences according to age, gender, and qualification of the respondents were identified. The responses obtained also acknowledged skills and competencies that the participants considered most important for a DPH practice and that would be important for students accepted into a DPH graduate program. Conclusions This needs assessment survey represents a preliminary step in establishing a DPH graduate program that addresses current gaps in knowledge and in the practice of public health

    Introduction. Juvenile Idiopathic Arthritis (JIA) is the most common chronic arthritis in children. Our aim is to describe demographic, clinical, and laboratory characteristics and treatment of JIA patients followed up in Pediatric Rheumatology clinic in a tertiary center in Saudi Arabia. Methods. Medical records of all patients who are followed up between January 2007 and January 2015 were retrospectively reviewed. Data were collected about demographic, clinical, and laboratory features and treatment. Results. Total patients were 82, males were 31 (37.8%), and mean age of JIA onset was 7.1 ± 3.6 yr. Mean follow-up duration was 2.67±1.6 yr. Systemic onset JIA (SoJIA) was the commonest (36.5%), followed by polyarticular in 29.2% and oligoarticular in 28%. Large and small joints are involved in 76 (92%) and 30 (36.6%), respectively. Main extra-articular feature was fever in 34 (41.4%). Uveitis was diagnosed in 7 (8.5%) and in 5 (21.7%) of oligoarticular JIA. Anemia was found in 49 (59.7%), high ESR in 45 (54.8%), and leukocytosis and thrombocytosis in 33 (40.2%). Positive ANA was found in 30 (36.5%) mainly in oligoarticular subtype as 12 (52%) patients (out of 23) had this positive test. 9 patients (10.9%) required NSAIDs only, 6 patients (7.3%) required NSAIDs and intra-articular steroids only, and 19 (23%) required NSAIDs, methotrexate, steroids, and biologics. Conclusion. SoJIA is the most common JIA subtype in our study. A population based rather than a single center study will give more details about JIA characteristics in Saudi Arabia PMID:26966610

    Background. This study described various molecular and epidemiological characters determining antibiotic resistance patterns in Pseudomonas aeruginosa isolates. Methods. A total of 34 carbapenem-resistant P. aeruginosa clinical isolates were isolated from samples collected at a tertiary hospital in Riyadh, Saudi Arabia, from January to December 2011. Susceptibility testing, serotyping, molecular characterization of carbapenem resistance, and pulsed-field gel electrophoresis (PFGE) were performed. Results. All isolates were resistant to ceftazidime, and more than half were highly resistant (minimum inhibitory concentration (MIC) > 256 mg/L). Fifteen isolates had MIC values ≥64 mg/L for any of the carbapenems examined. Vietnamese extended-spectrum β-lactamase (VEB-1) (n = 16/34) and oxacillinase (OXA-10) (n = 14/34) were the most prevalent extended-spectrum β-lactamase and penicillinase, respectively. Verona imipenemase (VIM-1, VIM-2, VIM-4, VIM-11, and VIM-28) and imipenemase (IMP-7) variants were found in metallo-β-lactamase producers. A decrease in outer membrane porin gene (oprD) expression was seen in nine isolates, and an increase in efflux pump gene (MexAB) expression was detected in five isolates. Six serotypes (O:1, O:4, O:7, O:10, O:11, and O:15) were found among the 34 isolates. The predominant serotype was O:11 (16 isolates), followed by O:15 (nine isolates). PFGE analysis of the 34 carbapenem-resistant P. aeruginosa isolates revealed 14 different pulsotypes. Conclusions. These results revealed diverse mechanisms conferring carbapenem resistance to P. aeruginosa isolates from Saudi Arabia. PMID:27597874

    The emergence of resistance to last-resort antibiotics is a public health concern of global scale. Besides direct person-to-person propagation, environmental pathways might contribute to the dissemination of antibiotic-resistant bacteria and antibiotic resistance genes (ARGs). Here, we describe the incidence of blaNDM-1, a gene conferring resistance to carbapenems, in the wastewater of the city of Jeddah, Saudi Arabia, over a 1-year period. blaNDM-1 was detected at concentrations ranging from 104 to 105 copies/m3 of untreated wastewater during the entire monitoring period. These results indicate the ubiquity and high incidence of blaNDM-1 in the local wastewater. To track the bacteria carrying blaNDM-1, we isolated Escherichia coli PI7, a strain of sequence type 101 (ST101), from wastewater around the Hajj event in October 2013. Genome sequencing of this strain revealed an extensive repertoire of ARGs as well as virulence and invasive traits. These traits were further confirmed by antibiotic resistance profiling and in vitro cell internalization in HeLa cell cultures. Given that this strain remains viable even after a certain duration in the sewerage, and that Jeddah lacks a robust sanitary infrastructure to fully capture all generated sewage, the presence of this bacterium in the untreated wastewater represents a potential hazard to the local public health. To the best of our knowledge, this is the first report of a blaNDM-1-positive E. coli strain isolated from a nonnosocomial environment in Saudi Arabia and may set a priority concern for the need to establish improved surveillance for carbapenem-resistant E. coli in the country and nearby regions.

    Smoking is recognized as a health problem worldwide and there is an established tobacco epidemic in Saudi Arabia as in many other countries, with tobacco users at increased risk of developing many diseases. This cross sectional study was conducted to assess the prevalence of oral mucosal, potentially malignant or malignant, lesions associated with tobacco use among a stratified cluster sample of adults in Jeddah, Saudi Arabia. A sample size of 599 was collected and each participant underwent clinical conventional oral examination and filled a questionnaire providing information on demographics, tobacco use and other relevant habits. The most common form of tobacco used was cigarette smoking (65.6 %) followed by Shisha or Moasel (38.1%), while chewing tobacco, betel nuts and gat accounted for 21-2%, 7.7%, and 5% respectively. A high prevalence (88.8%) of soft tissue lesions was found among the tobacco users examined, and a wide range of lesions were detected, about 50% having hairy tongue, 36% smoker's melanosis, 28.9% stomatitis nicotina, 27% frictional keratosis, 26.7% fissured tongue, 26% gingival or periodontal inflammation and finally 20% leukodema. Suspicious potentially malignant lesions affected 10.5% of the subjects, most prevalent being keratosis (6.3%), leukoplakia (2.3%), erythroplakia (0.7%), oral submucous fibrosis (0.5%) and lichenoid lesions (0.4%), these being associated with male gender, lower level of education, presence of diabetes and a chewing tobacco habit. It is concluded that smoking was associated with a wide range of oral mucosal lesions , those suspicious for malignancy being linked with chewable forms, indicating serious effects.

    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.

    Introduction: The restoration of posterior teeth with composite restoration is a common clinical practice nowadays. Opinions regarding posterior composite restorations vary among dentists. The aim of the present study was to determine the knowledge and opinions of general dental practitioners towards composite resins for posterior teeth restorations. Materials and Methods: A questionnaire was devised to elicit information regarding placement of composite restoration in posterior teeth in northern Saudi Arabia. It was distributed to 230 dentists by hand and e-mail. A response rate 136 (59%) was obtained. The questionnaire sought details about case selection criteria for composite restoration, problems associated with composites and reasons for selecting composite restoration in posterior teeth. The data was processed and analysed by SPSS statistical software 19. Frequencies and percentages were calculated for various responses of the participants. Results: Regarding the selection of composite restoration in posterior teeth, 97% of the dentists did not prefer composite placement for class I restoration with heavy occlusal contacts. 83% of the participants did not select composite for class II restoration. 78% of the respondents opted for restoring composites in small defects. Patients’ aesthetic demands (90%), amalgam replacement (22%) and restoration of endodontically treated teeth (42%) were the contributing factors. Regarding the problems associated with posterior composite restorations. Recurrent caries (87%), post-operative sensitivity (84%), restoration fracture (83%) and polymerization shrinkage (73%) were the major problems reported by respondents associated with composite restorations. The other minor concerns were wear (60%), contact build up in case of class II cavity restorations (51%) and isolation for composite restorations (36%). Conservative cavity preparation (78%), aesthetics (73%) and patient preference (65%) were the main reasons for choosing

    Groundwater quality monitoring is one of the most important aspects in groundwater studies in arid environments particularly in developing countries, like Saudi Arabia, due to the fast population growth and the expansion of irrigated agriculture and industrial uses. Groundwater samples have been collected from eight locations in Al-Ula in Saudi Arabia during June 2012 and January 2013 in order to investigate the hydrochemical characteristics and the groundwater quality and to understand the sources of dissolved ions. Physicochemical parameters of groundwater such as electrical conductivity, pH, total dissolved solid, and major cations and anions were determined. Chloride was found to be the dominant anion followed by HCO(-) 3 and SO4 (2-). Groundwater of the study area is characterized by the dominance of alkaline earths (Ca(2+) + Mg(2+)) over alkali metals (Na(+) + K(+)). The analytical results show that the groundwater is generally moderately hard and slightly alkaline in nature. The binary relationships of the major ions reveal that water quality of the Al-Ula region is mainly controlled by rock weathering, evaporation, and ion exchange reactions. Piper diagram was constructed to identify hydrochemical facies, and it was found that majority of the samples belong to Ca-Cl and mixed Ca-Mg-Cl facies. Chemical indices like chloro-alkali indices, sodium adsorption ratio, percentage of sodium, residual sodium carbonate, and permeability index were calculated. Also, the results show that the chemical composition of groundwater sources of Al-Ula is strongly influenced by lithology of country rocks rather than anthropogenic activities. PMID:25655124

    Objectives: To study the knowledge, attitudes, and practices with regard to human immunodeficiency virus infection / acquired immune deficiency syndrome (HIV/AIDS) in illegal residents, in the Kingdom of Saudi Arabia (KSA). Materials and Methods: A questionnaire study was conducted among the illegal residents from four regions in Saudi Arabia: Jeddah, Makkah, Riyadh, and Jazan. 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. PMID:26392717

    Background. This study described various molecular and epidemiological characters determining antibiotic resistance patterns in Pseudomonas aeruginosa isolates. Methods. A total of 34 carbapenem-resistant P. aeruginosa clinical isolates were isolated from samples collected at a tertiary hospital in Riyadh, Saudi Arabia, from January to December 2011. Susceptibility testing, serotyping, molecular characterization of carbapenem resistance, and pulsed-field gel electrophoresis (PFGE) were performed. Results. All isolates were resistant to ceftazidime, and more than half were highly resistant (minimum inhibitory concentration (MIC) > 256 mg/L). Fifteen isolates had MIC values ≥64 mg/L for any of the carbapenems examined. Vietnamese extended-spectrum β-lactamase (VEB-1) (n = 16/34) and oxacillinase (OXA-10) (n = 14/34) were the most prevalent extended-spectrum β-lactamase and penicillinase, respectively. Verona imipenemase (VIM-1, VIM-2, VIM-4, VIM-11, and VIM-28) and imipenemase (IMP-7) variants were found in metallo-β-lactamase producers. A decrease in outer membrane porin gene (oprD) expression was seen in nine isolates, and an increase in efflux pump gene (MexAB) expression was detected in five isolates. Six serotypes (O:1, O:4, O:7, O:10, O:11, and O:15) were found among the 34 isolates. The predominant serotype was O:11 (16 isolates), followed by O:15 (nine isolates). PFGE analysis of the 34 carbapenem-resistant P. aeruginosa isolates revealed 14 different pulsotypes. Conclusions. These results revealed diverse mechanisms conferring carbapenem resistance to P. aeruginosa isolates from Saudi Arabia.

    The emergence of resistance to last-resort antibiotics is a public health concern of global scale. Besides direct person-to-person propagation, environmental pathways might contribute to the dissemination of antibiotic-resistant bacteria and antibiotic resistance genes (ARGs). Here, we describe the incidence of blaNDM-1, a gene conferring resistance to carbapenems, in the wastewater of the city of Jeddah, Saudi Arabia, over a 1-year period. blaNDM-1 was detected at concentrations ranging from 10(4) to 10(5) copies/m(3) of untreated wastewater during the entire monitoring period. These results indicate the ubiquity and high incidence of blaNDM-1 in the local wastewater. To track the bacteria carrying blaNDM-1, we isolated Escherichia coli PI7, a strain of sequence type 101 (ST101), from wastewater around the Hajj event in October 2013. Genome sequencing of this strain revealed an extensive repertoire of ARGs as well as virulence and invasive traits. These traits were further confirmed by antibiotic resistance profiling and in vitro cell internalization in HeLa cell cultures. Given that this strain remains viable even after a certain duration in the sewerage, and that Jeddah lacks a robust sanitary infrastructure to fully capture all generated sewage, the presence of this bacterium in the untreated wastewater represents a potential hazard to the local public health. To the best of our knowledge, this is the first report of a blaNDM-1-positive E. coli strain isolated from a nonnosocomial environment in Saudi Arabia and may set a priority concern for the need to establish improved surveillance for carbapenem-resistant E. coli in the country and nearby regions.

    A quantitative method based on ultrasound-assisted toluene extraction followed by liquid chromatography-electrospray ionization-tandem mass spectrometry for the analysis of C60 and C70 fullerenes, N-methylfulleropyrrolidine, [6, 6]-phenyl C61 butyric acid methyl ester and [6, 6]-thienyl C61 butyric acid methyl ester has been developed. The method was validated using fortified blank river sediments according to the criteria of Commission Decision 2002/657/EC. The method limits of detection ranged from 14 to 290 pg/g, making it suitable for its application in environmental analysis. The method has been applied to investigate fullerene content in 58 soil samples collected from different urban and industrial areas in Saudi Arabia and in river sediment from six different sites in the Llobregat River Basin. In addition, in the case of the Llobregat River, superficial water samples from the same sites of the sediments were collected and analysed using a previous method. In soils from Saudi Arabia, C60-fullerene was the only compound that was detected and quantified in 19% of samples. In the sediments of the Llobregat River, C60-fullerene was also the only one detected (33% of the samples), while in river water, C70-fullerene was the most frequent compound, and it was quantified in 67% of the samples. However, C60-fullerene was present in two of the six samples, but at higher concentrations than C70-fullerene, ranging from 0.9 to 7.8 ng/L. PMID:23545859

    Objective: Sandstorms are metrological events and frequently occur in many regions throughout the world. Sandstorms are a main source of long-distance transport of dust, air pollution and cause various health problems. This study aimed to investigate the acute respiratory and general health complaints in subjects exposed to sandstorm at Riyadh, Saudi Arabia. Methodology: The present descriptive study was conducted in the Department of Physiology, College of Medicine, King Saud University, Riyadh, Saudi Arabia during the period March 2011- June 2012. We selected 517 (308 males, 59.58%) and (209 females, 40.42%), apparently healthy volunteers with mean age 28.6± 3.14 years, who had single outside exposure to sandstorm for the period of 24±2.68 minutes. The acute respiratory and general health complaints were recorded through a comprehensive questionnaire. Results: A large proportion of the subjects who were exposed to sandstorm had complaints of cough 247 (47.77%), runny nose 264(51.06%), wheeze 173(33.46%), acute asthmatic attack 108 (20.88%), eye irritation / redness 252(48.74%), headache 179 (34.62%), body ache 199 (38.5%), sleep disturbance 157(30.36%) and psychological disturbances 194 (37.52%). Conclusion: Exposure to sandstorm causes cough, runny nose, wheeze, acute asthmatic attack, eye irritation / redness, headache, body ache, sleep and psychological disturbances. These results indicate that sandstorm is a prolific source of respiratory and general ailments. It is therefore, suggested that an unnecessary exposure to sandstorm must be avoided. PMID:24353595

    Background/Aim: Hepatitis C virus genotypes 4 (HCV-4) is the most prevalent genotype in Saudi Arabia, although it's various subtypes, mode and route of transmission remains unknown. The aim of this study was to analyze (i) the variability of the HCV-4 subtypes, the route and source of HCV transmission and (ii) the influence of HCV-4 subtypes on their therapeutic response. Patients and Methods: Sixty-four HCV-4 patients were analyzed retrospectively for the prevalence of various sub-genotypes and the possible mode of transmission, and it was correlated with their treatment response to pegylated interferon (PEG-IFN) α-2a and ribavirin therapy. Results: Positive history of blood or blood products transfusion was noted in 22 patients (34%), hemodialysis in 10 patients (15.6%), surgery in 7 patients (11%), and unknown etiology in 25 patients (39%). Prevalence of HCV-4 subtypes was 4a = 48.4% (31/64), 4d = 39% (25/64), 4n = 6.25% (4/64), and remaining combined (4m, 4l, 4r, 4o) 6.25% (4/64). No significant correlation between subtypes and the source of transmission was recognized (P = 0.62). Sustained virological response in all HCV-4 patients was 64% (41/64), while in each subtypes separately it was 4a 77.4% (24/31), 4d 52% (13/25), and combined (4n, 4m, 4l, 4r, 4o) 62.5% (5/8) (P = 0.046). Conclusion: No obvious cause for the mode of HCV transmission was noted in majority of the patients. No significant correlation was observed between HCV-4 subtypes and the source of HCV infection. 4a and 4d subtypes were the most common in Saudi Arabia, and patients infected with 4a subtype responded significantly better to combination therapy than to 4d subtype.

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

    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.

    Atmospheric dust over Saudi Arabia during 2000-2010 has been studied using satellite and ground-based Aerosol Optical Depth (AOD), as well as station observations of dust occurrence. These datasets show a consistent seasonal cycle in dust activity, which peaks in spring to summer due to high surface temperatures, causing high atmospheric instability, and favorable wind patterns. Anomalies in these datasets are highly correlated on the monthly time scale, and statistically consistent on the daily time scale. Two remotely-sensed AOD datasets from Multi-angle Imaging SpectroRadiometer (MISR) and Moderate Resolution Imaging Spectroradiometer (MODIS) are validated with AOD measured by AEronet Robotic NETwork (AERONET) at Solar Village (24.9N, 46.4 E). The temporal correlation is higher between MODIS and AERONET on the monthly scale, but higher between MISR and AERONET on the daily scale. Meanwhile, MODIS AOD better captures the monthly dust frequency reported by dust observations from 17 stations across the country. The performance of satellite sensors on different temporal scales can be explained by the different levels of data coverage. The performance of satellite sensors also varies with the temporal and spatial scales of dust storms at various locations. We conclude that remotely-sensed AOD data can be applied as a reliable index of atmospheric dust concentration over Saudi Arabia on the monthly and daily time scales. Climatology of annual mean MISR-AOD (unitless: color shading), MODIS-AOD (unitless: contour) and the probability of dust storm occurrence at each station (size of the dot indicates the probability, computed as the number of days with recorded dust divided by the total number of days) during 2000-2010. Areas with MODIS-AOD above 0.3 are shaded with dots.

    Injury was the largest single cause of disability-adjusted life years and death in the Kingdom of Saudi Arabia in 2013. The vast majority of injury-related fatalities are deaths caused by road traffic. Measures to control this serious public health issue, which has significant consequences for both Saudi families and the Saudi economy as a whole, have been underway for years but with little success. Most attempts at intervening revolve around attempts for enforcing stricter traffic laws and by installing automated traffic monitoring systems that will catch law breakers on camera and issue tickets and fines. While there has been much research on various factors that play a role in the high rate of road traffic injury in The Kingdom (e.g., driver behavior, animal collisions, disobeying traffic and pedestrian signals, environmental elements), virtually no attention has been given to examining why Saudi drivers behave the way that they do. This review provides a thorough account of the present situation in Saudi Arabia and discusses how health behavior theory can be used to gain a better understanding of driver behavior. PMID:27747208

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

    Background: Rising incidence of human papillomavirus (HPV) infection and cervical cancer can be reduced by effective vaccination. Saudi Food and Drug Administration approved prophylactic HPV vaccine in 2010 for females of 11–26 years. Objectives: To determine the awareness of HPV infection, its health sequel and the attitude and barriers to the acceptance of HPV vaccine by young women in Saudi Arabia. Dynamics influencing the decision of patients and parents regarding vaccination were assessed to foster effective and strategically focused interventions. Materials and Methods: All patients of Family Medicine department, King Faisal Specialist Hospital and Research Center, Riyadh were invited to participate in this study from January 2012 to June 2014. A culturally sensitive and specially designed questionnaire was administered using an interview-based model to assess the knowledge, perception, and associated sociodemographic factors of HPV. Results: A total of 325 patients participated as per the inclusion criteria: 87.4% were Saudis, 53.5% had university or higher education and 65.2% were adolescents (age 11-19 years). The questionnaire was answered by participants (50.8%) or guardians (49.2%). About 34.5% of the population was aware of HPV infection, and 27.4% were aware of its relation with cervical cancer. However, awareness of the HPV vaccine, perception of its prevention of cervical cancer and other HPV-related disease was relatively low (32.3%), Saudis (29.9%) versus non-Saudis (48.8%) (P = 0.016). More guardians (41.2%) were aware of the HPV vaccine and its impact than participants (27.9%) (P = 0.01). Higher educational background (43.1%) increased the knowledge of HPV compared to less than high school education (24.5%) (odds ratio: 2.33; 95% confidence interval: 1.44–3.76). Nearly 64.3% of participants agreed, and 35.7% refused to receive the HPV vaccine. Conclusion: Knowledge and perception of HPV infection as an sexually transmitted infections and its

    Background Palliative care is not yet integrated into the health-care system in Saudi Arabia. King Faisal Specialist Hospital and Research Centre-Riyadh (KFSH&RC-Riyadh) is a tertiary care facility and regional cancer centre in Saudia Arabia with a highly multinational nursing workforce. Little is known about these nurses' knowledge of and attitudes towards palliative care. Aim To determine the palliative care knowledge and attitudes of the nursing workforce of KFSH&RC-Riyadh and any influencing factors. Method A questionnaire including demographic data, the Palliative Care Quiz for Nurses (PCQN), and Frommelt Attitude Toward Care of the Dying scale (FATCOD) was completed by 395 staff nurses from 19 countries. Results The nurses scored a mean of 111.66 out of 150 on the FATCOD scale and of 9.06 out of 20 on the PCQN. These scores indicate moderate attitudes towards but a knowledge deficit regarding palliative care. The nurses' palliative care training and years of nursing experience significantly affected the scores. The level of palliative care integration in the nurses' home countries was the most significant factor in multiple regression tests. Conclusion Palliative care integration into the health-care system of the country in which nurses train significantly influences their knowledge of and attitudes towards palliative care. Incorporating palliative care into nursing education might promote positive attitudes towards palliative care in nurses while enhancing their knowledge and skills.

    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.

  4. Origin and migration of hydrocarbons in the Paleozoic system of Saudi Arabia

    This paper is a progress report on geochemical studies of the sub-Khuff Paleozoic rocks in Saudi Arabia, summarizing current laboratory results from both Saudi Aramco and American companies and their preliminary interpretations. From oil/oil and oil/rock correlations as well as maturity modeling, it may be concluded that sweet sub-Khuff oils, condensates, and gases are closely related to each other, and are derived from a common source: the hot shales of the basal Qusaiba Formation (Lower Silurian). The hydrocarbons that have been discovered in the Hawtah trend must have migrated updip from the presently overmature Rub-Al-Khali depocenter, where oil generation was initiated as early as 160 Ma. The oil window in the Rub-Al-Khali embayment, where active oil and condensate generation is taking place at present, is at depths between approximately 10,000 and 14,000 ft. Oil accumulation housed at depths more than approximately 14,000 {plus minus} 500 ft are being cracked into gas and condensate depending on variations in the generally low geothermal gradients of 1.5 {plus minus} 0.1F/100 ft. The residue of this natural refinery process is pyrobitumen, or deal oil, that is a pore plugging agent in many reservoirs at these depths. All products have very low-sulfur kerogen. The economic impact of these findings is very significant.

    Helicobacter pylori is recognized as a major cause of gastritis, peptic ulcer, gastric cancer, and mucosa-associated lymphoma. Infection with this gram-negative microaerophile has been treated using combination of antibiotics and proton pump inhibitors for different gastrointestinal diseases. The most commonly used treatment is triple therapy which consists of administration of a proton pump inhibitor, clarithromycin, and amoxicillin. Many factors contribute to treatment failure, but one of the main reasons is development of bacterial antibiotic resistance. The percent prevalence of antibiotic resistance varies among different countries; it appears to be partly determined by the geographic factors and its ability to undergo frequent homologous recombination. The aim of this paper is to review the prevalence of H. pylori infection, association of clinical outcomes with H. pylori genotypes, and current status of antibiotic resistance in H. pylori in Saudi Arabia. It also discusses the different alternative approaches for the treatment of H. pylori using antibiotics. In addition, association of antibiotic resistance with H. pylori virulent genotypes in Saudi population and its underlying resistance mechanism will also be discussed. PMID:25038206

    Social media has the potential to improve women's health in developing countries through health education and promotion. In the Arab world, women's health interventions are lacking. However, with a high penetration rate of social media in the Arab world, there is good opportunity to utilize social media platforms such as Twitter to promote women's health. In this paper, we analyze the Tweet feeds of Saudi-based Twitter account to promote women's health. A total of 5167 Tweets were extracted and analyzed retrospectively, using NVivo Ncapture between June 2014 and March 2015. There were a total number of 3449 followers by March 20, 2015. Results showed that a majority of the Twitter followers (61%, n=2104) were seeking gynecological information, followed by pregnancy related information (27%, n=931), breast-feeding advice (9%, n=310), and other health related information (3%, n=103). Results also showed an increased level of health awareness and comprehension among Twitter followers. Further research is needed to promote women's health in Saudi Arabia and the Arab world through social media platforms such as Twitter and similar platforms including Instagram, Facebook, and YouTube which are also popular in the Arab world.

    Aim To analyze the experience and knowledge of dental practitioners in Saudi Arabia regarding the identification of child abuse and neglect (CAN), to identify barriers that prevent the reporting of suspected cases of child maltreatment by dental practitioners, and to assess the need for training dentists in child protection. Methods A self-administered, web-based questionnaire was emailed to all of the members of the Saudi Dental Society (n = 7352) in 2012. Results The respondents (n = 122) demonstrated good knowledge of the forms and indicators of CAN. Moreover, a large proportion (59%) had experienced a case of child abuse or neglect in their practice over the previous five years. However, only about 10% of these respondents made a report. Fear of family reprisal, lack of certainty about the diagnosis of child maltreatment, and uncertainty about case management were critical barriers to the reporting of the suspected child maltreatment. In addition, only 20.9% of the respondents reported having knowledge of a child protection policy in their workplace. Conclusions Based on the results of this survey, it appears that the level of knowledge among the respondents regarding the forms and indicators of CAN is good. However, a large proportion of respondents did not take action regarding suspected cases of CAN in their practice over the past five years. Therefore, additional resources and training are needed to support the identification and management of cases of child maltreatment by dental practitioners. PMID:25057227

    Objective: The aim of this study was to assess the level of knowledge and attitude of Saudi dental students in the management of dental trauma in children. Materials and Methods: A self-administered questionnaire comprising 17 close-ended questions was used in this survey. The questions were divided into three parts including: Personal and professional profile; knowledge assessment; attitude toward dental trauma. Data of 307 respondents were analyzed using SPSS (Statistical Package for Social Studies) version 22.0 (IBM Corporation, Chicago, IL, USA). Results: The response rate was 76.8%. Around 40.3% of students reported attending additional courses about dental trauma with a significant difference between males (57.2%) and females (19.4%). The vast majority of students (95.7%) stressed the importance of dental trauma education. While 77% could correctly identify the media of transportation of an avulsed tooth, only 26.9% of the students knew the proper method of transportation. Regarding the knowledge of immediate replantation, only 67.5% of students responded correctly. Conclusion: The present study demonstrates an insufficient knowledge concerning dental trauma management among dental students in Saudi Arabia. This highlights the need to improve the knowledge of dental students regarding dental trauma and its management using a variety of educational methods such as problem-based learning and powering the curriculum concerning those topics of dental trauma.

    Middle East respiratory syndrome (MERS) caused by novel Corona virus hit Kingdom of Saudi Arabia (KSA) and resulted in hundreds of mortality and morbidity, fears and psychosocial stress among population, economic loss and major political change at Ministry of Health (MoH). Although MERS discovered two years ago, confusion still exists about its origin, nature, and consequences. In 2003, similar virus (SARS) hit Canada and resulted in a reform of Canada's public health system and creation of a Canadian Agency for Public Health, similar to the US Centers for Disease Control (CDC). The idea of Saudi CDC is attractive and even "sexy" but it is not the best option. Experience and literature indicate that the best option for KSA is to revitalize national public health systems on the basis of comprehensive, continuing, and integrated primary health care (PHC) and public health (PH). This article proposes three initial, but essential, steps for such revitalization to take place: political will and support, integration of PHC and PH, and on-job professional programs for the workforce. In addition, current academic and training programs for PHC and PH should be revisited in the light of national vision and strategy that aim for high quality products that protect and promote healthy nation. Scientific associations, medical education research chair, and relevant academic bodies should be involved in the revitalization to ensure quality of process and outcomes. PMID:25803593

    Group A rotavirus is responsible for inducing severe diarrhea in young children worldwide. Rotavirus vaccines are used to control the disease in many countries. In the current study, the sequences of human rotavirus G and P types in Saudi Arabia are reported and compared to different relevant published sequences. In addition, the VP4 and VP7 genes of the G1P[8] strains are compared to different antigenic epitopes of the rotavirus vaccines. Stool samples were collected from children under 2 years suffering from severe diarrhea. Screening of the rotavirus-positive samples was performed with rapid antigen detection kit. RNA was amplified from rotavirus-positive samples by reverse transcriptase polymerase chain reaction assay for both VP4 and VP7 genes. Direct sequencing of the VP4 and VP7 genes was conducted and the obtained sequences were compared to each other and to the rotavirus vaccines. Both G1P[8] G1P[4] genotypes were detected. Phylogenetic analysis revealed that the detected strains belong to G1 lineage 1 and 2, P[8] lineage 3, and to P[4] lineage 5. Multiple amino acid substitutions were detected between the Saudi RVA strains and the commonly used vaccines. The current findings emphasize the importance of the continuous surveillance of the circulating rotavirus strains, which is crucial for monitoring virus evolution and helping in predicting the protection level afforded by rotavirus vaccines.

    New cases of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) were reported in Gulf countries in 2014, and to date, it has reportedly infected 837 people and killed 291 globally. Awareness of an individual's knowledge and being able to predict his or her behavior is crucial when evaluating clinical preparedness for pandemics with a highly pathogenic virus. The aim of this study was to identify awareness, attitudes, and practices related to MERS-CoV among the public in Saudi Arabia. A cross-sectional study of 1147 adult subjects recruited from various shopping malls in Riyadh was conducted. All the subjects were interviewed using a questionnaire that tested their knowledge, attitudes, and use of precautionary measures in relation to the MERS-CoV pandemic. The majority of the participants showed high levels of concern and had utilized precautionary measures. After adjusting for other variables, gender was the only significant predictor of the level of concern (P < .001), while knowledge was the significant predictor of both the level of concern and precaution (P < .001). High concern translated into a higher compliance with precautionary recommendations. Frequent communication between health care providers and the public is recommended to help dispel myths about the disease and to empower the public with the information needed to help the Saudi government in containing the disease outbreak.

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

    Coronary Artery Disease (CAD) remains the leading cause of mortality worldwide. Mortality rates associated with CAD have shown an exceptional increase particularly in fast developing economies like the Kingdom of Saudi Arabia (KSA). Over the past twenty years, CAD has become the leading cause of death in KSA and has reached epidemic proportions. This rise is undoubtedly caused by fast urbanization that is associated with a life-style that promotes CAD. However, the question remains whether genetics play a significant role and whether genetic susceptibility is increased in KSA compared to the well-studied Western European populations. Therefore, we performed an Exome-wide association study (EWAS) in 832 patients and 1,076 controls of Saudi Arabian origin to test whether population specific, strong genetic risk factors for CAD exist, or whether the polygenic risk score for known genetic risk factors for CAD, lipids, and Type 2 Diabetes show evidence for an enriched genetic burden. Our results do not show significant associations for a single genetic locus. However, the heritability estimate for CAD for this population was high (h2 = 0.53, S.E. = 0.1, p = 4e-12) and we observed a significant association of the polygenic risk score for CAD that demonstrates that the population of KSA, at least in part, shares the genetic risk associated to CAD in Western populations.

    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. PMID:27022605

    Objectives: Epilepsy is a very common chronic neurological disorder in children throughout the world. This study was conducted to assess Saudi male schoolteachers’ knowledge of epilepsy and practice in Southern Saudi Arabia. Subjects and Methods: A cross-sectional descriptive study was conducted among male teachers; 315 teachers filled a well-designed and pretested self administered questionnaire. Results: Approximately three-quarters (72.7%) of the schoolteachers had witnessed epileptic fits. Forty-six percent believed that epilepsy was caused by electrical discharges. Most of the school teachers (79.7%) disagreed with the idea of teaching children with epilepsy separately, or preventing them from sporting activity (50.5%). In addition, 94.9% disagreed with the idea that epilepsy was shameful. Unfortunately, 64.1% of the teachers who were exposed to cases of seizures were not able to provide first aid to students having epileptic fits (P = 0.03). Conclusions: The schoolteachers were generally knowledgeable about epilepsy. This fact can be used to design a national program through which teachers can help to bring about a well-informed and tolerant community toward epileptics. PMID:26392797

    In this study the case records of 1414 patients who delivered at Alshaty hospital within one year were examined and some important variables related to caesarean section cases and their outcome were discussed. The caesarean section rate was found to be 9.9%. The high number of grand multigravida and primigravida among these Saudi mothers have contributed to this high caesarean section rate. The high emergencies in these sections (73.6%) have resulted in higher incidence of maternal and fetal morbidity namely postoperative pyrexia (37%), maternal anemia (20%) and extensive neonatal resuscitation (34%). The main indications of caesarean section in this hospital were repeated caesarean section (34.3%), failure of progress (19.3%) and fetal distress 12.9%. The relation and interaction between the three groups were thoroughly discussed based on the mechanisms of these indications. It is concluded that the changing trend of indications of caesarean section was mostly related to the change in departmental management rather than change in the characteristics of the patients.

    Objectives To examine the effect of most common studied single nucleotide polymorphisms (SNP) on serum 25-hydroxyvitamin D (25OHD) levels in Saudi Arabian population. Method A cross-sectional observational study was carried out between July 2014 and October 2015, at King Fahd Hospital of the University (KFHU), Al-Khobar, Kingdom of Saudi Arabia. After informed consent, blood samples from 283 subjects living in the Eastern province were collected for 25-OHD measurement and genetic analysis of SNPs in vitamin D receptor (VDR) [rs2228570 and rs1544410], Cytochrome, P450 family 2 (CYP2R1) [rs10741657 and rs1993116], and Group-specific components (GC) [rs2282679 and rs4588]. Results Vitamin D deficiency was found in 87.6% and insufficiency in 7.7%. The percentages of the different alleles of the 6 SNPs tested ranged between 0-62.5%. There was significant difference between the AA, AG, and GG alleles of VDR rs2228570. The carries of GG allele was associated with increased risks of vitamin D insufficiency (p<0.002) and deficiency (p≤0.005). The CYP2R1 rs10741657 gene showed that AG and GG allele carriers had significant risk of vitamin D deficiency. AG allele (normal versus Insufficiency p<0.02 and normal versus deficiency p<0.08) and GG allele normal versus deficiency (p<0.002) and insufficiency versus deficiency (p<0.001). For group-specific components (GC rs4588), there was only significant difference between the normal and deficiency for the AC allele (p<0.0001). Conclusion The presence of GG allele of the SNP rs2228570 of VDR gene, SNPs rs4588 of GC gene and CYP2R1 rs10741657 gene was associated with vitamin D deficiency. PMID:27570856

    The medicolegal death investigation system in the Kingdom of Saudi Arabia (KSA) is unique in the world. It is exclusively derived from Islamic judiciary based on Shari'ah law, which is the definitive Islamic law or doctrine. This law is applied on Saudi citizens as well as foreigners. This is different from other Islamic countries, which have a combination of Islamic and other judiciary systems.The forensic medicine centers in KSA are related administratively to the Ministry of Health (MOH) and its subdivisions in the different governorates. They are concerned with forensic medical examination and autopsy, as well as the clinical forensic medical examination of sexual assault cases, and those injured in civil and criminal cases. The assisting laboratories (forensic histopathology, microbiology, serology, forensic chemistry) are working independently under the funding of MOH, whereas the DNA laboratory and other departments of forensic sciences, for example, counterfeiting and forgery unit are related administratively to the Ministry of Interior represented by the Administration of Criminal Evidences. Efforts concerning crime scene investigations are shared with Administration of Criminal Evidences' crime scene investigators.Forensic medicine education in KSA developed in the past few years after the foundation of Saudi specialty certificate in forensic medicine. The certificate is a postgraduation qualification equivalent to a doctorate degree in forensic medicine and requires completion of a 4-year training program in both MOH- and Ministry of Interior-related departments, as well as passing annual evaluation and examination.This review is aimed at providing in the next decade the medicolegal centers with national forensic specialists throughout the kingdom and granting skillful headships for the next generations. Moreover, this review suggests more scientific associations with the academic universities in the various fields of forensic sciences through academic

    Objectives Complementary and alternative medicine (CAM) is well established worldwide. The present work is aimed at studying the knowledge, attitude and practice of CAM by the people of Riyadh region, Saudi Arabia. Methods A cross-sectional descriptive household survey study of the people living in Riyadh city, as well as the surrounding governorates. A multistage random sample was taken from 1st January to the end of March 2010, with a total number of 518 participants. Data were collected using a pre-designed questionnaire through direct interview. The data was collected based on socio-demography, as well as knowledge, attitude and practice of CAM. Results Participants were nearly sex-matched, consisting of approximately 70% Saudi and 30% non-Saudis. About 89% of the participants had some knowledge of CAM. Mass media e.g. (T.V., newspapers and radio) and family, relatives and friends represented the main sources of CAM knowledge, (46.5% and 46.3% respectively). Nearly 85% of participants or one of their family members has used some form of CAM before, and the most common users of CAM practices were females, housewives, and illiterate subjects (or those who could just read and write), as well as participants aged 60 years and above. Medical herbs (58.89%), prayer (54%), honey and bee products (54%), hijama (35.71%) and cauterization or medical massage therapy (22%) were the commonly used CAM practices. Most participants agreed that there are needs for; CAM practices (93.8%), regulations for CAM (94.9%), health education (96.6%), specialized centers (94.8%) and CAM clinics (92.7%). While only 8.3% of participants usually discussed CAM with their physicians. Conclusion There is a high prevalence and increased public interest in CAM use in the Riyadh region. There is a positive attitude towards CAM, yet most participants are reluctant to share and discuss CAM information with their physicians. PMID:22359720

    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

    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).

    Aedes aegypti (= Stegomyia aegypti) mosquito is a world vector of important arboviral diseases like dengue and Rift Valley fever. Despite its wide distribution in the western and southern regions of Saudi Arabia, where dengue outbreaks have occurred, its ecology is largely unknown. In this study we report on the main life table developmental attributes of a laboratory colony of Ae. aegypti reared from field-collected larvae from Madinah Province, west of Saudi Arabia. Females were maintained on daily blood meal and sugar. The female fecundity was ~62 eggs/female at an overall rate of 72% hatchability. The mean time needed for eggs to hatch into larvae was 4.5 d. The mean pupation time (P50) was 11.53 days (d). The proportion of immature survivorships were 0.69 for 1(st) larva to pupa (P/I), 0.98 for pupa to adult (A/P) and an overall 0.67 for 1(st) larva to adult (A/I). Males emerged faster than females with mean emergence time (E50) of 12.83 and 15.31 d, respectively. The average developmental velocity (V) showed that males (V= 0.081) developed faster than females (V= 0.068). The male/female sex ratio at adult emergence was 0.48, and insignificantly different from the 1:1 ratio. The adult mean life expectancy at emergence (eo) was 17.14 d for females compared to 9.59 d for males. The net reproductive rate (Ro) was 101.04 and the intrinsic rate of increase (rm) was 0.15 with a mean generation time (G) of 30.7 d. The instantaneous mean of birth (B) and death rate (D) were 0.30 and 0.15, respectively, with rm/B of 0.529 and B/D of 2.281. Compared to other Ae. aegypti strains from different geographic and ecological settings, the Saudi strain had a relatively low colonization potential. This is the first report on life table characteristics for Ae. aegypti from the Arabian Peninsula, and provides base-line information for wider studies on its natural populations. This is particularly important for understanding its population dynamics in relation to dengue

    In the spring of 1984, a hydrogeochemical survey was conducted in the Kingdom of Saudi Arabia to test ground water as a sampling medium in exploration for mineral deposits. Eighty-one water samples (mostly from wells) were collected. The samples were analysed for the presence and concentration of major cations and anions, as well as a suite of trace elements. Most of the water samples contained high concentrations of dissolved salts. The majority of the samples showed no significant amounts of the trace elements. A few well-water samples contained moderately anomalous concentrations of zinc, molybdenum, and uranium. These anomalies could be due to salinity effects, contamination, or the proximity of mineral sources. This survey has established some baseline water-chemistry data, especially for the trace metals, which to date have not been reported in ground water in the Kingdom of 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.

    The objective of this paper is to investigate the experiences of using a digital marketing platform to promote the use of an internet based health encyclopedia in Saudi Arabia. Key informant interviews, meeting documentation, and Google Analytics were the data collection sources used in the study. Findings show that using a digital marketing platform led to a significant increase in the number of visitors to the health encyclopedia. The results demonstrate that digital marketing platforms are effective tools to be used for promoting internet based health education interventions. Future work will examine long-term educational impacts and costs in using digital marketing platforms to promote online healthcare sites in Saudi Arabia. PMID:25676939

    Nonsyndromic hearing loss (NSHL) affects a substantial proportion of newborns in the world every year. This proportion increases proportionally with the degree of consanguineous marriages in any society. In the Kingdom of Saudi Arabia, consanguineous marriages are common practice and this is associated with a noticeably high frequency of inherited conditions affecting the resulting progeny, including NSHL. Until now there is no published data on the genetic causes of NSHL in Saudi Arabia, which greatly hindered the ability of local genetic counseling and family planning centers to distinguish between hereditary and nonhereditary forms of NSHL and subsequently could not give information on the possible inheritance of deafness. In addition, the lack of validated genetic tests for NSHL delayed the detection of deafness in affected individuals and may have lowered the efficiency of later medical interventions. Further, the population covered in this study is likely to have a multiethnic background caused by decades of religious and economic migration to this region. To address such problems, we undertook the task of unraveling the genetic causes of hearing loss in Saudi Arabia, starting with identifying the GJB2/DFNB1 mutation spectrum in a cohort of unrelated individuals suffering from mild to profound NSHL. A total of 12 reported GJB2 mutations were identified in 17 out of 109 (15.59%) NSHL cases. Biallelic GJB2 mutations were identified in 11 out of the 109 NSHL cases (10.09%), with c.35delG being the most common (7/11, 63.63%). The remaining six patients were found to have monoallelic GJB2 mutations. Interestingly, biallelic GJB2 mutations were not detected in patients of Arab tribal origins, reflecting the genetic heterogeneity of the western area of the Kingdom of Saudi Arabia. Therefore, ethnically targeted genetic screening for GJB2 mutations could be a useful tool toward the management of NSHL in this area. PMID:19929407

    Carbapenem-resistant Acinetobacter spp. have been increasingly reported worldwide including Saudi Arabia and Egypt. We examined 64, non-repetitive, Acinetobacter baumannii isolates collected in 2013 and 2014 from four different medical centres (two from Saudi Arabia and two from Egypt). All the isolates were resistant to ceftazidime and ciprofloxacin. The intI1 harbouring blaGES-11 and aac-6'-1b was detected in 19% (n=12) of the isolates. ISAba1 over-expression of blaADC gene was observed in 65% (n=42) of isolates. Of all the isolates 19% (n=12) had ISAba1 upstream of the blaOXA-51-like gene, 69% (n=44) carried the blaOXA-23 gene within the Tn2006 structure, 8% (n=5) had blaOXA-24-like gene and 9% (n=6) harboured either blaVIM-2 or blaNDM-1 gene. Eighty nine percent (n=57) of isolates were resistant to imipenem and had an MIC of ≥8mg/L. Pulsed-field gel electrophoresis (PFGE) typing revealed the presence of 23 different PFGE. Three PFGE types were very widespread, ST236 (CC104) (PFGE type 1, n=15), ST208 (CC92) (PFGE type 2, n=10), ST884 (CC unassigned) (PFGE type 3, n=7) in and across all four medical centres. The blaOXA-23 gene was found to be present on a 60kb transferable plasmid in both PFGE type 1 and 2 but was absent in PFGE type 3. This is the first study to report on the emergence of ST236 in Saudi Arabia and Egypt, and spread of distinct carbapenem resistant A. baumannii clones belonging to ST884, ST945 and ST1096 in Saudi Arabia.

    The incubation period is an important epidemiologic distribution, it is often incorporated in case definitions, used to determine appropriate quarantine periods, and is an input to mathematical modeling studies. Middle East Respiratory Syndrome coronavirus (MERS) is an emerging infectious disease in the Arabian Peninsula. There was a large outbreak of MERS in South Korea in 2015. We examined the incubation period distribution of MERS coronavirus infection for cases in South Korea and in Saudi Arabia. Using parametric and nonparametric methods, we estimated a mean incubation period of 6.9 days (95% credibility interval: 6.3–7.5) for cases in South Korea and 5.0 days (95% credibility interval: 4.0–6.6) among cases in Saudi Arabia. In a log-linear regression model, the mean incubation period was 1.42 times longer (95% credibility interval: 1.18–1.71) among cases in South Korea compared to Saudi Arabia. The variation that we identified in the incubation period distribution between locations could be associated with differences in ascertainment or reporting of exposure dates and illness onset dates, differences in the source or mode of infection, or environmental differences.

    Background The sandfly Phlebotomus papatasi is the vector of Leishmania major, the main causative agent of Old World cutaneous leishmaniasis (CL) in Saudi Arabia. Sandflies inject saliva while feeding and the salivary protein PpSP32 was previously shown to be a biomarker for bite exposure. Here we used recombinant PpSP32 to evaluate human exposure to Ph. papatasi bites, and study the association between antibody response to saliva and CL in endemic areas in Saudi Arabia. Methodology/Principal Findings In this observational study, anti-PpSP32 antibodies, as indicators of exposure to sandfly bites, were measured in sera from healthy individuals and patients from endemic regions in Saudi Arabia with active and cured CL. Ph. papatasi was identified as the primary CL vector in the study area. Anti-PpSP32 antibody levels were significantly higher in CL patients presenting active infections from all geographical regions compared to CL cured and healthy individuals. Furthermore, higher anti-PpSP32 antibody levels correlated with the prevalence and type of CL lesions (nodular vs. papular) observed in patients, especially non-local construction workers. Conclusions Our findings suggest a possible correlation between the type of immunity generated by the exposure to sandfly bites and disease outcome. PMID:25646796

    Corchorus (Corchorus capsularis L. and Corchorus olitorius L.) is one of the most important fiber crops grown in tropical and subtropical regions throughout the world. Field survey was conducted and naturally infected leaf samples were collected from corchorus and tomato plants in Jeddah, Saudi Arabia. The causal virus was transmitted by whiteflies to tomato plants and begomovirus infection was confirmed by Polymerase chain reaction. The complete viral genome and associated betasatellites were amplified, cloned and sequenced from both corchorus and tomato samples. The genetic variability and phylogenetic relationships were determined for both isolates (corchorus and tomato). The complete genome sequences showed highest (99.5 % nt) similarity with tomato yellow leaf curl virus (TYLCV) and formed closest cluster with TYLCV-Tomato reported from Jizan and Al-Qasim, Saudi Arabia and betasatellites sequences showed highest similarity (99.8 % nt) with Tomato yellow leaf curl betasatellites-Jeddah followed by Tomato yellow leaf curl Oman betasatellites and formed closed cluster with TYLCV-Tomato. On the basis of results obtained from whiteflies transmission, sequence similarity and phylogenetic relationships; it is concluded that the identified virus could be a variant of TYLCV circulating in the Kingdom. The significance of this study demonstrated that the corchorus is serving as reservoir and alternative host and playing an important role in spreading the begomovirus associated disease in the Kingdom of Saudi Arabia.

    Inter simple sequence repeats (ISSR) analysis was used to determine the genetic diversity among 15 genotypes of sorghum [Sorghum bicolor (L.) Moench] growing in some parts of Saudi Arabia and Yemen. A total of 92 alleles were amplified, with an average of 13 ISSR alleles per primer. Cluster analysis divided the 15 genotypes into two main groups. Group A consisted of five genotypes with white grains from Jazan and Abha with a similarity coefficient range of 0.527 to 0.818. Group B was comprised of 10 genotypes; two genotypes from Al-Qassim were clearly delimited from the remaining eight samples with a coefficient range from 0.709 to 0.490. The eight genotypes were divided into two clusters; one was comprised of landraces with dark grains from Abha in Saudi Arabia and Ab in Yemen, with a similarity coefficient range between 0.563 and 0.781, and the other cluster was differentiated into three white-colored-grain genotypes and one colored-grain genotype; all samples from North Yemen had a similarity coefficient range from 0.454 to 0.800. The current results encourage further collection and authentication of sorghum landraces in the gene banks of Saudi Arabia.

Two independent researchers in consultation with several experts used 4 electronic databases (ISI Web of Knowledge, Science Direct, PubMed, and Cochrane) to scrutinize articles published from January 2000 - March 2014. Each of the studies was given a quality assessment rating of weak, moderate, or strong, and was evaluated for methodological soundness using Russell and Gregory’s criteria. Results: The online literature search identified 12 studies that met the inclusion criteria. Lack of knowledge of non-Muslim nurses or culture in Saudi Arabia, difficulties in achieving cultural competence, and culture shock were documented as cultural difference factors. Issues in language difference include the clarity of language use by health care providers in giving information and providing adequate explanation regarding their activities. Conclusion: The available information provided by this review study shows that there is a communication barrier between patients and health care workers such as healthcare workers demonstrate low cultural competency. Despite the fact that the government provides programs for expatriate healthcare workers, there is a need to further improve educational and orientation programs regarding the culture and language in Saudi Arabia.

    Tomato is an important vegetable crop and its production is adversely affected by leaf curl disease caused by begomovirus. Leaf curl disease is a serious concern for tomato crops caused by begomovirus in Jeddah, Kingdom of Saudi Arabia. Tomato leaf curl disease has been shown to be mainly caused either by tomato leaf curl Sudan virus or tomato yellow leaf curl virus as well as tomato leaf curl Oman virus. Many tomato plants infected with monopartite begomoviruses were also found to harbor a symptom enhancing betasatellites. Here we report the association of tomato leaf curl Sudan virus causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia. The complete genome sequence analysis showed highest (99.9 %) identity with tomato leaf curl Sudan virus causing leaf curl disease in Arabian Peninsula. In phylogenetic relationships analysis, the identified virus formed closest cluster with tomato leaf curl Sudan virus. In recombination analysis study, the major parent was identified as tomato leaf curl Sudan virus. Findings of this study strongly supports the associated virus is a variant of tomato leaf curl Sudan virus causing disease in Sudan, Yemen and Arabian Peninsula. The betasatellites sequence analysis showed highest identity (99.8 %) with tomato leaf curl betasatellites-Amaranthus-Jeddah. The phylogenetic analysis result based on betasatellites formed closed cluster with tomato yellow leaf curl Oman betasatellites. The importance of these findings and occurrence of begomovirus in new geographic regions causing leaf curl disease of tomato in Jeddah, Kingdom of Saudi Arabia are discussed.

    Corchorus (Corchorus capsularis L. and Corchorus olitorius L.) is one of the most important fiber crops grown in tropical and subtropical regions throughout the world. Field survey was conducted and naturally infected leaf samples were collected from corchorus and tomato plants in Jeddah, Saudi Arabia. The causal virus was transmitted by whiteflies to tomato plants and begomovirus infection was confirmed by Polymerase chain reaction. The complete viral genome and associated betasatellites were amplified, cloned and sequenced from both corchorus and tomato samples. The genetic variability and phylogenetic relationships were determined for both isolates (corchorus and tomato). The complete genome sequences showed highest (99.5 % nt) similarity with tomato yellow leaf curl virus (TYLCV) and formed closest cluster with TYLCV-Tomato reported from Jizan and Al-Qasim, Saudi Arabia and betasatellites sequences showed highest similarity (99.8 % nt) with Tomato yellow leaf curl betasatellites-Jeddah followed by Tomato yellow leaf curl Oman betasatellites and formed closed cluster with TYLCV-Tomato. On the basis of results obtained from whiteflies transmission, sequence similarity and phylogenetic relationships; it is concluded that the identified virus could be a variant of TYLCV circulating in the Kingdom. The significance of this study demonstrated that the corchorus is serving as reservoir and alternative host and playing an important role in spreading the begomovirus associated disease in the Kingdom of Saudi Arabia.

    Al-Abdulkarim, Bander B.

    The increasing fluctuations in the oil prices through the last decades have been transferred to the oil exporting countries. Thus, many oil exporting countries experienced significant changes in the economic activity due to changes in the oil markets. In light of this, oil exporting countries have attempted to implement a policy that would stabilize the fluctuations in the oil markets recognizing the adverse effects of such behavior on oil exporting countries, as well as oil importing countries. Saudi Arabia, as the largest oil-exporting country and a member of OPEC, takes the role of oil-markets stabilizer by behaving as the swing producer. This role has caused the global economic fluctuations to transfer into the domestic economy. In addition, Saudi Arabian government has adopted a fixed exchange rate currency regime. Although it has contributed to domestic price stabilizations, this policy has also exposed the country to global economic disturbances. The purpose of the study is to empirically investigate these aspects for Saudi Arabia. First, the effects of shocks originated in the international markets on the Saudi Arabian economy. Second, how the fixed exchange rate regimes influences the domestic macroeconomic variables. Third, to what extent the oil sector contributes to the non-oil domestic fluctuations. Finally, how the findings from the study can be explained by economic theory. In pursuing this, there are four economic theories that are considered to explain the causes of business cycles. These theories are Classical Theory, Keynesian Theory, Monetarist Theory, and the Real Business Cycles. In addition, a theoretical model is derived that is suitable for an oil-based economy. The model follows the set up of McCallum and Nelson (1999). Then, the empirical models of Structural Vector Autoregression (SVAR) and Error Correction Model (ECM) are implemented with three different specifications: Choleski Decomposition, Block Exogeneity and long-run Cointegration

    Objective The use of antimicrobial agents has been increased, leading to bacterial resistance. Therefore the health professionals should have a sound knowledge about the prescription of antibiotics to overcome the increasing bacterial resistance. The main objective of this study was to evaluate the attitudes of dentists towards the prescription of antibiotics during endodontic treatment in north of Saudi Arabia. Materials and Methods This was a survey based descriptive cross-sectional study. This study has been done among the dentists of northern region of Saudi Arabia. A questionnaire was designed, regarding pattern of prescription of antibiotics by the dentists in the north of Saudi Arabia and the use of antibiotics in the treatment of different endodontic conditions during endodontic treatment. This questionnaire was distributed among 200 dentists in the north of Saudi Arabia. This study will encourage the dentists of the northern region of Saudi Arabia to be up to date about the current and prospective guidelines for the prescription of antibiotics and follow these guidelines for the antibiotic prescription. Results The collected information was analysed by using a computer software SPSS version 18. Majority of the dentists were male accounting for 86%. The age range for 68% of the respondents was 25-35 years. Most of the dentists were having just a basic dental qualification i.e. 65.60%. Out of the total responding dentists, 50% were working in the ministry of health. 77% of the respondents prescribed the antibiotics for necrotic pulp with acute apical periodontitis; swelling present; mod/ severe preoperative symptoms. Out of the total responding dentists, 45.2% prescribed amoxicillin and clavulanic acid combination as the drug of choice. Conclusion It is concluded from the present study that the dentists should know the scientific basis for the prescription of antibiotics during endodontic therapy. They should follow and should not neglect the current

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

    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.

    Since the Physicians start use of antibiotics long ago with un-notice drug resistance. However actual problem was recognized about 85 years ago. Antibiotic resistant and Multi-drug resistant bacterial strains are at rise throughout the world. It is physicians and researchers to take scientific research based appropriate action to overcome this ever-spreading problem. This study is designed to find out sensitive (S), resistant (R) and multi-drug resistant (MDR) Acinetobacter baumanii strain along with other isolates in the resident patients of Eastern Region of Saudi Arabia. Pseudomonas aeruginosa is excluded from other gram-negative organisms isolated from different sites as it will be dealt separately. This study is based in was retrospective observations designed to collect data of different stains of Acinetobacter baumanii with reference to their Sensitivity (S), Resistance (R), Multi-Drug Resistance (MDR) along with other Gram negative isolated from different sites (from 1st January 2004 to 31st December 2011) at King Abdulaziz Hospital located Eastern Region of Kingdom of Saudi Arabia (KSA). All necessary techniques were used to culture and perform sensitivity of these isolates. There were 4532 isolates out of which 3018 (67%) were from patients. Out of Acinetobacter baumanii infected were 906 (20%) while other 3626 (80%) isolates were miscellaneous. Numbers of patients or cases were 480 (53%) out of 906 isolates and numbers of patients or cases in other organisms were 2538 (70%) out of 3626 isolates. Acinetobacter baumanii infected patients 221 (46%) were male and 259 (54%) were female and the male and female ratio of 1:1.2. In other organisms this male female ratio was almost same. There was steady rise in number of patients and the hence the isolates from 2004 to 2011. Majority of the bacterial strains were isolated as single organism but some were isolated as double or triple or quadruple or more organisms from different sites. Sensitive, Resistant and

    The purpose of this study was to describe the present status of geography education in boys' intermediate schools in Riyadh, Saudi Arabia as perceived by geography teachers and supervisors; that is, to investigate the objectives, content, methods of teaching, tools and resources that are available and used in classrooms, evaluation techniques, and problems encountered in the teaching of geography. To collect data from this representative sample population, a questionnaire was developed by the researcher specifically for this study. Questionnaire data was collected from 19 social studies supervisors and 213 geography teachers. Percentages, frequencies, means, and standard deviations were computed for each questionnaire item. Chi Square tests were applied to determine if any significant differences could be identified between the observed and expected responses of supervisors and teachers. Major findings of the study indicated that both supervisors and teachers tend to strongly support the identified geography objectives. Most teachers and supervisors also indicated that the current geography curriculum contains enough information about Saudi Arabia, the Arabic world, and the Islamic world. In addition, the also indicated that geography content promotes a sense of patriotism and cultural pride. Responses indicated that educators see deficiencies in the content: it does not focus sufficiently on current events nor on developing student skills such as research and technical skills like drawing maps. Lecture and discussion are the most commonly used strategies in the teaching of geography. Field trips, role-playing, scientific competitions, scientific games, solving problems, and individual learning are less commonly used. Teaching tools most commonly used are wall maps and earth globes, whereas the use of geographical transparencies, models, and instruments is not common. Most of the teachers do lot use computers in their teaching. Evaluation techniques depend

    Continental extension is a fundamental plate tectonic process, and extensional environments are associated with significant production of basaltic magmas. Although tholeiitic magmatism produced by mantle decompression is common, dispersed, less voluminous and compositionally variable basaltic and related magmas also occur in association with continental extension. One of the most voluminous, best-preserved and least studied examples of the latter is the volcanic harrats of western Saudi Arabia. Uplift, crustal erosion and harrat volcanism occurred from ~15 Ma to recent over a considerable region of western Arabia. Volcanism trends north from the Red Sea along the Makkah-Madinah-Nafud (MMN) line as a number of discrete harrats, and geophysical evidence suggests this region is underlain by hot upwelling asthenosphere. Larger harrats occur along the central axis of the MMN line, with smaller fields on the periphery. We present initial results of an ongoing study of harrat volcanism, including more than 50 new 40Ar-39Ar ages together with geochemical and isotopic data. Magma storage and fractionation appears to have occurred at a range of crustal levels, including deep storage and transport sufficiently rapid to preserve a range of lithospheric and crustal xenoliths. Melting commenced within the garnet peridotite field, however modeling of REE element abundances suggest that considerable differences exist in the thickness of the overlying lithospheric lid. Thinner lithosphere (<40 km) and higher degrees of melting occurs along the MMN line, whereas harrats peripheral to the MMN line have thicker lithosphere (>60-80 km) and magmas result from lower degree melts. The observed variability can be explained by a process of progressively thinning lithosphere along the main axis of the MMN line, as a result of regional lithospheric extension and mantle decompression melting, coupled with northward asthenospheric flow from the Red Sea and/or Afar hot spot.

    Several challenging obstacles remain to increasing the number of organ donations from deceased patients in a hospital setting. These include medical, administrative, and ethical issues. Possible medical obstacles include the failure of early recognition of possible donors and inadequate care of potential and actual donors. To maximize the use of donated organs, proper care of the donors and expedited donor consent cannot be overemphasized. The care rendered to patients should ensure appropriate perfusion and nutrition of the organs, with meticulous follow-up until organ recovery. For example, patients involved in accidents are presumed to be healthy, but many have no available medical history on file. At the time of organ recovery, unexpected infections or malignancies can be minimized by raising the index of suspicion of the presence of serious conditions in donors, especially in donors with unknown medical history. A careful physical examination and an appropriate and aggressive laboratory investigation may disclose the cause of suspected clinical conditions in these potential donors. Individuals who work in intensive care units are the main group of health care providers directly involved in the process of organ donation. Appointing a donor coordinator in each intensive care unit could improve all aspects of organ donation. Such coordination could harmonize efforts toward the goals mentioned above and surmount the obstacles encountered during deceased-donor organ donation. Here, we describe the preliminary results of the Proactive Detection Program, a collaboration between the Saudi Center for Organ Transplantation (the national organ donation and transplant supervising center) and intensive care units of donating hospitals. With its success in Saudi Arabia, it is hoped that it will be widely adopted in other regions.

    Fetal haemoglobin (HbF) levels have been measured in 137 normal (AA) subjects, 109 with the sickle-cell trait (AS) and 237 with sickle-cell anaemia (SS) from the oasis population of Eastern Saudi Arabia. In addition the proportion of F-cells has been estimated in 71 AA, 51 AS and 34 SS subjects. The mean HbF% (and the range of F-cells %) were: AA 0.77 (0.3--18), AS 1.38 (2.3--43) and SS 25.56 (33--98). The distribution of Hb F was always heterocellular. The influence of pregnancy accounts for most of the excess female subjects with sickle-cell trait showing raised Hb F and F-cells. Whilst the normal Arabs and those with sickle-cell trait did not differ from comparable groups of American blacks, both the % Hb F and % F-cells in Saudi Arabian patients with sickle-cell anaemia were much higher than in Blacks. The high Hb F levels in individuals with sickle-cell anaemia are not due to coexistent glucose-6-phosphate dehydrogenase deficiency or alpha-thalassaemia trait, and the Hb F level showed an inverse correlation with the degree of haemolysis. These findings indicate that the unusually elevated levels of Hb F are not due to an associated high frequency of a gene for hetero-cellular hereditary persistence of fetal haemoglobin in the oasis population, but rather from a genetically determined absolute increase in Hb F production related in some way to the SS genotype.

    Poisoning is a medical emergency that represent a major health problem all over the world. Studies on drug overdose and chemical poisoning are very limited in Saudi Arabia (SA). We aimed to describe the current pattern and assess risk factors of drug overdose and chemical poisoning in King Khalid National Guard hospital, Jeddah, SA. Medical records of patients attended emergency department in King Khalid National Guard hospital during the period from January 2008 to December 2012 due to drug overdose and chemical poisoning were reviewed. A total of 129 cases were included in the study. The majority of the population was Saudi (97.7 %), and almost half of them were females (54.3 %). Children under 12 years were the most affected age group (44.2 %). Drug overdose was the most common cause of poisoning (92.2 %). Analgesics and non-steroidal anti-inflammatory drugs represented the highest percentage of used medications (20.4 %). The most commonly reported symptoms were symptoms of the central nervous system (57.4 %) followed by GIT symptoms (41.9 %). Intentional poisoning was reported in 34 cases (26.4 %). Female patients were significantly more likely to attempt suicide than male patients (OR = 7.22, 95 % CI = 1.70, 30.62). Children continue to be at high risk for medication and chemical poisoning. Accessibility to medications at homes encountered for most of poisoning cases among children. Implementing methods to raise public awareness and minimize children access to medications would significantly contribute to reducing burden of this problem on the community.

    AIM: This study aimed at assessing prevailing patterns and risk factors of tobacco consumption among clients, food handlers and employers of food facilities, in Riyadh, Saudi Arabia. METHODS: A cross-sectional approach to a representative sample of food facilities in Riyadh was used. A sample of 3000 participants included clients (75%); food handlers/hospitality workers (20 %) and employers (5 %). Participants were reached at restaurants, food courts or cafes. A modified version of the WHO-CDC-Global Youth Tobacco Survey questionnaire was used for data collection. RESULTS: The prevalence of tobacco use at food facilities was found to be 40.3 %, of which 74% were customers, 18.8% were food handlers and 7.2% were managers. The consumption of tobacco was higher at restaurants (39.9%), but lowest at food courts of shopping malls. Water pipe (55.3%) was the main consumption type, followed by cigarettes (42.6%) and chewing tobacco (2.1%). Multivariate analysis showed that gender (male), marital status (single), and type of food facility (Estaraha and café/coffee shop) were independent risk factors associated with tobacco use at food facilities. CONCLUSION: Tobacco use is very common in food facilities in Riyadh as reflected by results of our study, especially among single males Saudis. We should build on success encountered in banning smoking in airports, airplanes, shopping malls, market places, educational institutions and healthcare facilities, extending the ban to include food facilities as well. This is important for the health of non-smokers as well as smokers themselves. PMID:24987478

    Objectives: To estimate the prevalence of emergency cases reporting to Primary Health Care centers (PHC), Jeddah, Saudi Arabia and to explore the barriers facing PHC physicians when dealing with such emergency cases. Methods: A cross-sectional analytic study, where all physicians working in the PHC of the Ministry of Health (MOH) in Jeddah; were invited to participate (n=247). The study period was from July 2013 till December 2013. Data were collected through two sources. 1- A self-administered questionnaire used to determine the physicians’ perceived competence when dealing with emergency cases. 2- A structured observation sheet used to evaluate availability of equipment, drugs, ambulances and other supporting facilities required to deal with emergency cases. Results: The response rate was 83.4%. The physicians’ age ranged between 25 and 60 years with a mean ±SD of 34.4±7.5 years. Majority of them (83.5%) did not attend ATLS courses at all whereas 60.7% never attended ACLS courses. The majority (97.1%) had however attended BLS courses. Physicians in the age group 36-45 years, non-Saudi, those who had SBFM, those who reported experience in working in emergency departments and physicians who reported more working years in PHCCs (>5 years) had a significant higher score of perceived level of competence in performing emergency skill scale than others (P<0.05). The prevalence of emergency cases attending PHC in Jeddah (2013) was 5.2%. Conclusion: Emergency services at PHC in Jeddah are functioning reasonably well, but require fine tuning of services and an upgrade in their quality. PMID:27045411

    The clustering of risk factors predisposing an individual to cardiovascular morbidity and mortality are usually referred to as the 'metabolic syndrome' (MS). Several definitions exist, causing confusion to practicing clinicians. A consensus definition was reached by several major organizations stating that the presence of any three of five risk factors (abdominal obesity, elevated triglyceride, reduced high-density lipoprotein cholesterol, elevated blood pressure, and elevated fasting glucose) constitutes a diagnosis. Cutoff points for each of the risk factors were defined, taking into account ethnicity in case of abdominal obesity. The prevalence of MS has been reported to be on the rise globally, and was mainly attributed to changes in diet and lifestyle, in addition to genetic factors and metabolic susceptibility. The risk of cardiovascular disease (CVD) has almost doubled and the risk of developing type 2 diabetes mellitus (T2DM) has increased fivefold in individuals diagnosed with MS. The prevalence T2DM in Saudi Arabia is increasing, making it an epidemic health hazard. Intervention programs to decrease the risk of progression from MS to full T2DM, and later CVD have been successful in many countries. Therefore, diagnosing MS is important to address risk factors and to prevent progression to the more serious chronic conditions. The prevalence of MS in Saudi adults varies from 16% to 40% depending on the definition used and the study location. Use of the consensus definition might decrease the number of missed cases. However, in the absence of local cutoff points for various risk factors for MS, the use of ratios such as waist/hip ratio and low-density lipoprotein cholesterol/high-density lipoprotein cholesterol ratio, and family history of diabetes and CVD might aid diagnosis. Priority should be given to establishing national normal ranges, screening programs for hyperglycemia and hypertension, and community-directed programs to combat obesity and inactivity

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

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

    Objectives. This study was designed to compare the trainees' perception of emergency medicine (EM) training in the United States (US) and Saudi Arabia (SA) and to identify residents' levels of confidence and points of satisfaction in education, procedural skills, and work environment. Method. An IRB-exempt anonymous web-based survey was distributed to five EM residency training programs in the USA and three residency regions in SA. Results. 342 residents were polled with a 20% response rate (16.8% USA and 25.8% SA). The Saudi residents responded less positively to the questions about preparation for their boards' examinations, access to multiple educational resources, and weekly academic activities. The Saudi trainees felt less competent in less common procedures than US trainees. American trainees also more strongly agree that they have more faculty interest in their education compared to the Saudi trainees. The Saudi residents see more patients per hour compared to their US peers. Conclusion. These findings may be due to the differences in training techniques including less formal didactics and simulation experience in SA and more duty hour regulations in the USA. PMID:24563784

    OBJECTIVES. The purpose of this study was to determine whether respiratory disease due to crowded living conditions and high levels of suspended and blowing sand had a major adverse impact on US military personnel during Operation Desert Shield. METHODS. A questionnaire survey was administered to 2598 combat troops stationed in Northeast Saudi Arabia for a mean of 102 days. Samples of surface sand from seven different locations were analyzed by scanning electron microscopy and x-ray diffraction. RESULTS. Among surveyed troops, 34.4% reported a sore throat, 43.1% complained of a cough, 15.4% complained of chronic rhinorrhea, and 1.8% were unable to perform their routine duties because of upper respiratory symptoms. Evaluation of sleeping accommodations indicated that complaints of a sore throat and cough were most closely associated with sleeping in air-conditioned buildings; in contrast, complaints of rhinorrhea were associated with exposure to the outdoor environment while living in tents. Sand samples consisted mostly of quartz, with just 0.21% by weight of respirable size (< 10 microns in diameter). CONCLUSIONS. These findings indicate that upper respiratory complaints were frequent among Operation Desert Shield troops and were related both to the troops' housing and to their exposure to the outside environment.

    The aim of this study was to identify the main weed communities in Al-Jouf province in northern Saudi Arabia. Moreover, the composition and diversity of these communities were studied in relation to soil variables and crop type. Some 54 stands representing olive orchards, date palm orchards, wheat crop and watermelon crop were studied, using ten quadrats (1 × 1 m) per stand. A total of 71 species belonging to 22 families and 61 genera were observed. The classification of vegetation using the Two Way Indicator Species Analysis (TWINSPAN) resulted in the recognition of four vegetation groups representing wheat crop, orchards in winter season, orchards in summer season and watermelon crop. These results suggested the importance of both crop and season for the formation of weed community. Detrended Correspondence Analysis (DCA) showed that these groups are clearly distinguished by the first two DCA axes. The species richness was higher in both olive and date palm orchards than in wheat and watermelon crops. This pattern of species richness could be related to farm management practices and habitat micro-heterogeneity. Soil electrical conductivity, organic carbon and soil texture showed significant correlations with species richness and the cover values of some dominant species, suggesting the significant role of soil characteristics in weed community structure and diversity.

    The goals of chronic dialysis treatment for end-stage renal disease (ESRD) patients include restoration of the highest achievable state of personal physical health and preservation as well as restoration and development of the highest level of psychological and social functions. We conducted this study to evaluate factors influencing the process of adaptation such as religious faith, economic status and extended family-tribal system. It was hoped that studying these factors might provide further dimension to our understanding of the psychopathology of ESRD patients, and to help offer new ideas to improve the quality of their lives. A sample comprising 54 patients with ESRD was studied in Abha hemodialysis centre in Southern Saudi Arabia. The socio-demographic characteristics, clinical and laboratory data were collected. The psychiatric status of the patients was evaluated using a structured "The Comprehensive Psychiatric Rating Scale" (CPRS) clinical interview. The result indicated that the major co-morbidity (in 60% of these patients) was a depressive illness due to renal failure diagnosable according to DSM-IV criteria. Our study suggests the need for specific anti-depressant treatment in order to ameliorate many distressing symptoms, which may affect the quality of these patients' life. Concomitant social problems of poverty, absence of spouse and illiteracy, dictate a more prompt attitude in initiating support systems and attention to providing leisure activities.
