Head and neck cancer (HNC) is one of the deadliest cancers worldwide. Early detection is a key determinant of HNC prognosis. Hence, raising awareness of this disease may improve survival rates. The present study evaluated the level of awareness and screening status for HNC in the general population of Jeddah, Saudi Arabia. An e-questionnaire was distributed during our HNC awareness campaign at the Red Sea Mall in Jeddah. The questions assessed HNC knowledge and screening status among participants. Of the 112 respondents, 68% indicated that they had no knowledge of HNC. Social media was the major source of information (39%) for respondents. The majority (40%) believed that it was the joint responsibility of dentists, dental hygienists, and general physicians to screen for HNC; 82% had never been screened. Knowledge and awareness of HNC must be increased in the general population and among dental health professionals.

The current study was conducted to figure out the relationship between the social structure and the most predominant environmental kids diseases (1-12 years old) in the community of Jihad city through year 1423.A.H. The results revealed that the dominant husband and wives age-groups were 30-40 Y, couples had Bachelor education level and governmental employees. Residences were distributed between down town and its periphery toward north , apart of red sea coast. They had 2-4 child/family of equal gender ratio. Most of couples were non relative. Wives education level was positively correlated with kids skin, respiratory and ocular diseases but negatively correlated with presence of servant and her health certificate. Private hospitals and health care centers were permanently accessed and located far of industrial collections. Majority of teachers and students were Saudis. Schools subjected their students for regular vaccination programs offered by Health Ministry. School services and facilities (regular vaccination, healthy foods and water) significantly affected incidence and kinds of kids diseases. Mixing nationalities may represent risk health for coming exotic infection unless restricted hygienic measures offered by Health Ministry. Husband job was negatively correlated with respiratory diseases. Husband job sector and their work places indoor air quality, their smoking behavior may affect directly or indirectly child diseases.

Several studies have shown that water-borne 222 Rn contributes to indoor air concentrations. A passive radon measurement method was employed to determine radon activity concentrations in the water of Jeddah city (Saudi Arabia). Tap water, flushing water and drinking water, including natural mineral water, artificial mineral water and distilled water, have been investigated for their radon concentrations. It is observed that the radon concentration in natural mineral water samples is the highest and that in flush water, it is the lowest. From these measurements, the corresponding annual effective dose for the stomach and the lung are determined. It is found that the annual effective dose resulting from direct consumption of water is far greater than that due to inhalation of radon emanated from tap water and flushing water. Moreover, it is also seen that the annual effective dose resulting from inhalation of radon emanated from tap water and flushing water is negligible compared to the total annual effective dose for indoor radon in Jeddah.

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.

In this paper, a nonhydrostatic Weather Research and Forecasting (WRF) model has been used to simulate the extreme precipitation event of 25 November 2009, over Jeddah, Saudi Arabia. The model is integrated in three nested (27, 9, and 3 km) domains with the initial and boundary forcing derived from the NCEP reanalysis datasets. As a control experiment, the model integrated for 48 h initiated at 0000 UTC on 24 November 2009. The simulated rainfall in the control experiment depicts in well agreement with Tropical Rainfall Measurement Mission rainfall estimates in terms of intensity as well as spatio-temporal distribution. Results indicate that a strong low-level (850 hPa) wind over Jeddah and surrounding regions enhanced the moisture and temperature gradient and created a conditionally unstable atmosphere that favored the development of the mesoscale system. The influences of topography and heat exchange process in the atmosphere were investigated on the development of extreme precipitation event; two sensitivity experiments are carried out: one without topography and another without exchange of surface heating to the atmosphere. The results depict that both surface heating and topography played crucial role in determining the spatial distribution and intensity of the extreme rainfall over Jeddah. The topography favored enhanced uplift motion that further strengthened the low-level jet and hence the rainfall over Jeddah and adjacent areas. On the other hand, the absence of surface heating considerably reduced the simulated rainfall by 30% as compared to the observations.

This study aims to detect differences in eating behaviours demonstrated by adolescent girls in Jeddah Saudi Arabia, according to the influence of the media through TV advertisements. A cross-sectional survey was conducted of 1519 girls from 20 schools in Jeddah. Survey questions included information regarding media advertising and its effect on eating behaviour. Bivariate analyses were performed to define differences in eating behaviour according to media influence and Chi-square analyses to detect significant relationships. The results indicated a significant correlation between dessert consumption and advertising exposure (P = 0.035). Adolescent girls exposed to such advertising were more likely to consume dessert [n=299 (48.5%)], to shop for food [n=316 (50.7%)], and had attempted to lose weight [n=373 (59.5%)]. The results emphasize the role and obligation of decision-makers to protect young consumers through increased legislation and control of media content (particularly food advertisements) targeting young people.

Full Text Available The development of safe desalination plants with low environmental impact is as important an issue as the supply of drinking water. The desalination plant in Jeddah (Saudi Arabia, Red Sea coast produces freshwater from seawater by multi-stage flash distillation (MSFD and reverse osmosis (RO. The process produces brine as by-product, which is dumped into the sea. The aim of this study was to assess the impact of Jeddah desalination plant on the coastal water in the nearby of the plant. Total concentrations of dissolved Cu, Ni, Zn and nutrients in several locations around the plant were analyzed by cathodic stripping voltammetry. The average levels of dissolved Cu, Ni, and Zn on surface in the sampling locations were 15.02, 11.02, and 68.03 nM respectively, whereas the levels at the seafloor near the discharging point were much higher. Distribution of temperature, salinity, nutrients and dissolved oxygen were quite normal both on surface and in depth.

The measured data of global and diffuse solar radiation on a horizontal surface, the number of bright sunshine hours, mean daily ambient temperature, maximum and minimum ambient temperatures, relative humidity and amount of cloud cover for Jeddah (lat. 21 o 42'37''N, long. 39 o 11'12''E), Saudi Arabia, during the period (1996-2007) are analyzed. The monthly averages of daily values for these meteorological variables have been calculated. The data are then divided into two sets. The sub-data set I (1996-2004) are employed to develop empirical correlations between the monthly average of daily global solar radiation fraction (H/H 0 ) and the various weather parameters. The sub-data set II (2005-2007) are then used to evaluate the derived correlations. Furthermore, the total solar radiation on horizontal surfaces is separated into the beam and diffuses components. Empirical correlations for estimating the diffuse solar radiation incident on horizontal surfaces have been proposed. The total solar radiation incident on a tilted surface facing south H t with different tilt angles is then calculated using both Liu and Jordan isotropic model and Klucher's anisotropic model. It is inferred that the isotropic model is able to estimate H t more accurate than the anisotropic one. At the optimum tilt angle, the maximum value of H t is obtained as ∼36 (MJ/m 2 day) during January. Comparisons with 22 years average data of NASA SSE Model showed that the proposed correlations are able to predict the total annual energy on horizontal and tilted surfaces in Jeddah with a reasonable accuracy. It is also found that at Jeddah, the solar energy devices have to be tilted to face south with a tilt angle equals the latitude of the place in order to achieve the best performance all year round.

The impact of variational data assimilation for predicting two heavy rainfall events that caused devastating floods in Jeddah, Saudi Arabia is studied using the Weather Research and Forecasting (WRF) model. On 25 November 2009 and 26 January 2011, the city was deluged with more than double the annual rainfall amount caused by convective storms. We used a high resolution, two-way nested domain WRF model to simulate the two rainfall episodes. Simulations include control runs initialized with National Center for Environmental Prediction (NCEP) Global Forecasting System (GFS) data and 3-Dimensional Variational (3DVAR) data assimilation experiments conducted by assimilating NCEP prepbufr and radiance observations. Observations from Automated Weather Stations (AWS), synoptic charts, radar reflectivity and satellite pictures from the Presidency of Meteorology and Environment (PME), Jeddah, Saudi Arabia are used to assess the forecasting results. To evaluate the impact of the different assimilated observational datasets on the simulation of the major flooding event of 2009, we conducted 3DVAR experiments assimilating individual sources and a combination of all data sets. Results suggest that while the control run had a tendency to predict the storm earlier than observed, the assimilation of profile observations greatly improved the model\\'s thermodynamic structure and lead to better representation of simulated rainfall both in timing and amount. The experiment with assimilation of all available observations compared best with observed rainfall in terms of timing of the storm and rainfall distribution, demonstrating the importance of assimilating different types of observations. Retrospective experiments with and without data assimilation, for three different model lead times (48, 72 and 96-h), were performed to examine the skill of WRF model to predict the heavy rainfall events. Quantitative rainfall analysis of these simulations suggests that 48-h lead time runs with

The expansion of the medicalisation of childbirth has been described in the literature as being a global phenomenon. The vignette described in this paper, selected from an ethnographic study of routine intervention in Saudi Arabian hospitals illustrates how the worldwide spread of the bio-medical model does not take place within a cultural vacuum. To illuminate the ways in which the medicalisation of birth may be understood and practised in different cultural settings, through a vignette of a specific birth, drawn as a typical case from an ethnographic study that investigated clinical decision-making in the second stage of labour in Saudi Arabia. Ethnographic data collection methods, including participant observation and interviews. The data presented in this paper are drawn from ethnographic field notes collected during field work in Saudi Arabia, and informed by analysis of a wider set of field notes and interviews with professionals working in this context. While the medicalisation of care is a universal phenomenon, the ways in which the care of women is managed using routine medical intervention are framed by the local cultural context in which these practices take place. The ethnographic data presented in this paper shows the medicalisation of birth thesis to be incomplete. The evidence presented in this paper illustrates how local belief systems are not so much subsumed by the expansion of the bio-medical model of childbirth, rather they may actively facilitate a process of localised reinterpretation of such universalised and standardised practices. In this case, aspects of the social and cultural context of Jeddah operates to intensify the biomedical model at the expense of respectful maternity care. In this article, field note data on the birth of one Saudi Arabian woman is used as an illustration of how the medicalisation of childbirth has been appropriated and reinterpreted in Jeddah, Saudi Arabia.

This study was conducted to examine the prevalence of smoking and the smoking habits among male secondary school students in Jeddah, Kingdom of Saudi Arabia and to assess their knowledge and attitudes towards smoking. A cross-sectional study was conducted in Jeddah, using a two-stage cluster sample that randomly selected four schools from 85 public secondary schools for males. Data were obtained through a self-administered questionnaire containing questions on personal background, smoking behavior, knowledge, and behavior and attitudes towards smoking. A total of 695 students responded to the questionnaires with an 87.4% response rate. The age range of this student sample was 16-22 years. Two hundred fifty-eight (37%) of the study group were current smokers. The most common reasons given for smoking were personal choice (50.8%) and the peer pressure from smoker friends (32.8%). Many students researched the smoking hazards (68.1%), but only 47.6% knew about the bad effects of passive smoking. Two thirds of the smoking students wanted to quit smoking (63.2%), especially if suitable help was available, and 75.1% tried to quit. A third of the smoking students (36.8%) found it difficult to stop smoking in no-smoking areas. A well-planned integrated antismoking campaign is urgently required, especially among students and teachers. Our study revealed that smoking prevalence was high, which will lead to future high smoking-related health problems if proper preventive measures are not taken accordingly.

Full Text Available This work discusses the composition and characteristic of the surficial sediments in the southern corniche of Jeddah, Saudi Red Sea coast, in an attempt to infer the surficial distribution pattern of minerals and provenance of sediments. Twenty-six superficial sediments samples were collected from backreef and forereef areas and were analyzed for grain size, CaCO3 content, and mineralogy. The textural of grain size range from gravel to mud fraction. The mud-dominated substrates (<63 µm occur generally in the back-reef area near the shoreline (sheltered area and in the lagoon. Gravel rich-sediments are mostly found in forereef regions. The highest content of aragonite and Mg-calcite occur in the forereef area, probably because to suitability the forereef region for chemical and biochemical precipitation of these minerals. High Mg-calcite and Dolomite are low in both the regions. The pyrite occurs in lagoon; this indicates the reductive conditions in this part. However, on the contrary the percentage of carbonate minerals were low in the backreef-flat area, which could be attributed to the supply of non-carbonate terrigenous materials. The terrigenous material contains quartz, k-feldspar, plagioclase and amphibole minerals and are dominant in backreef-flat area with averages of 12.7%, 7.13%, 2.93% and 0.65%, respectively. Their abundance could be attributed to the supply of terrigenous materials by Aeolian deposits and intermittent Wadis.

This study provides the first comprehensive analysis of the seasonal variations and weekday/weekend differences in fine (aerodynamic diameter Saudi Arabia. Air quality samples were collected over 1 yr, from June 2011 to May 2012 at a frequency of three times per week, and analyzed. The average mass concentrations of PM 2.5 (21.9 μg/m 3 ) and PM 10 (107.8 μg/m 3 ) during the sampling period exceeded the recommended annual average levels by the World Health Organization (WHO) for PM 2.5 (10 μg/m 3 ) and PM 10 (20 μg/m 3 ), respectively. Similar to other Middle Eastern locales, PM 2.5-10 is the prevailing mass component of atmospheric particulate matter at Jeddah, accounting for approximately 80% of the PM 10 mass. Considerations of enrichment factors, absolute principal component analysis (APCA), concentration roses, and backward trajectories identified the following source categories for both PM 2.5 and PM 2.5-10 : (1) soil/road dust, (2) incineration, and (3) traffic; and for PM 2.5 only, (4) residual oil burning. Soil/road dust accounted for a major portion of both the PM 2.5 (27%) and PM 2.5-10 (77%) mass, and the largest source contributor for PM 2.5 was from residual oil burning (63%). Temporal variations of PM 2.5-10 and PM 2.5 were observed, with the elevated concentration levels observed for mass during the spring (due to increased dust storm frequency) and on weekdays (due to increased traffic). The predominant role of windblown soil and road dust in both the PM 2.5 and PM 2.5-10 masses in this city may have implications regarding the toxicity of these particles versus those in the Western world where most PM health assessments have been made in the past. These results support the need for region-specific epidemiological investigations to be conducted and considered in future PM standard setting. Temporal variations of fine and coarse PM mass, elemental constituents, and sources were examined in Jeddah, Saudi Arabia, for the first time. The main source

Following Chernobyl reactor accident, King Abdulaziz University (KAU) was assigned the responsibility of monitoring food imports reaching the western ports of Saudi Arabia. This includes the three western seaports of Jeddah, Yanbu and Jizan and the airport of Jeddah. Through the seaport of Jeddah, the largest in Saudi Arabia, essentially all kinds of foodstuffs are entering. Chilled meat, fresh vegetables and other items that can not be stored for long time are coming through Jeddah airport, while Jizan and Yanbu handle mainly barley and animal feed. The monitoring program started in the middle of June. This is the time when pilgrimage season starts and about one million persons come from different parts of the world to the city of Mecca. Food imports drastically increases during this time and large number of live sheep and cows are imported for religious sacrifice

Isolation and characterization of NDM-positive Escherichia coli from municipal wastewater in Jeddah, 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 Jeddah city over a one-year period. blaNDM-1 was detected at concentrations ranging from 104 to 105 copies per 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 the sequence type 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 would represent 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 isolated from a non-nosocomial environment in Saudi Arabia, and may set a preceding concern for the need to establish an improved surveillance for carbapenem-resistant E. coli in the country and nearby regions.

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.

Road dusts were collected from five different functional areas (traffic areas (TA), parking areas (PA), residential areas (RA), mixed residential commercial areas (MCRA) and suburban areas (SA)) in Jeddah and one in a rural area (RUA) in Hada Al Sham. We aimed to measure the pollution levels of heavy metals and estimate their health risk of human exposure applying risk assessment models described by United States Environmental Protection Agency (USEPA). Using geo-accumulation index (I geo ), the pollution level of heavy metals in urban road dusts was in the following order Cd > As > Pb > Zn > Cu > Ni > Cr > V > Mn > Co > Fe. Urban road dust was found to be moderately to heavily contaminated with As, Pb and Zn, and heavily to extremely contaminated with Cd. Calculation of enrichment factor (EF) revealed that heavy metals in TA had the highest values compared to that of the other functional areas. Cd, As, Pb, Zn and Cu were severely enriched, while Mn, V, Co, Ni and Cr were moderately enriched. Fe was considered as a natural element and consequently excluded. The concentrations of heavy metals in road dusts of functional areas were in the following order: TA > PA > MCRA > SA > RA > RUA. The study revealed that both children and adults in all studied areas having health quotient (HQ) exposure route was ingestion. The cancer risk for children and adults from exposure to Pb, Cd, Co, Ni, and Cr was found to be negligible (≤1 × 10 -6 ).

Full Text Available Type 2 (T2DM is believed to be common in Saudi Arabia, but data are limited. In this population survey, we determined the prevalence of T2DM and prediabetes.A representative sample among residents aged ≥ 18 years of the city of Jeddah was obtained comprising both Saudi and non-Saudi families (N = 1420. Data on dietary, clinical and socio-demographic characteristics were collected and anthropometric measurements taken. Fasting plasma glucose and glycated hemoglobin (HbA1c were used to diagnose diabetes and prediabetes employing American Diabetes Association criteria. Multiple logistic regression analysis was used to identify factors associated with T2DM.Age and sex standardized prevalence of prediabetes was 9.0% (95% CI 7.5-10.5; 9.4% (7.1-11.8 in men and 8.6% (6.6-10.6 in women. For DM it was 12.1% (10.7-13.5; 12.9% (10.7-13.5 in men and 11.4% (9.5-13.3 in women. The prevalence based on World Population as standard was 18.3% for DM and 11.9% for prediabetes. The prevalence of DM and prediabetes increased with age. Of people aged ≥50 years 46% of men and 44% of women had DM. Prediabetes and DM were associated with various measures of adiposity. DM was also associated with and family history of dyslipidemia in women, cardiovascular disease in men, and with hypertension, dyslipidemia and family history of diabetes in both sexes.Age was the strongest predictor of DM and prediabetes followed by obesity. Of people aged 50 years or over almost half had DM and another 10-15% had prediabetes leaving only a small proportion of people in this age group with normoglycemia. Since we did not use an oral glucose tolerance test the true prevalence of DM and prediabetes is thus likely to be even higher than reported here. These results demonstrate the urgent need to develop primary prevention strategies for type 2 diabetes in Saudi Arabia.

Increasing levels of atmospheric pollution is observed to accentuate and accelerate the degradation of historical sites. This paper investigates the chemical and mineralogical characteristic of the building materials used to construct the declared UNESCO world heritage site located in Jeddah, Saudi Arabia., and provide an initial assessment of the primary mechanisms for their environmental degradation. Stone and plaster samples were collected from six historic houses as well as the quarry from which the stone was originally produced. The main objective of this work was to identify the composition and alteration of the stone, plaster and quarry materials and to provide information about the decay mechanisms, thereby better enabling conservators to identify the correct methods and materials for onwards conservation and restoration works. X-ray Diffraction (XRD), Laser Raman spectroscopy (LRS) and Scanning Electron Microscopy combined with energy-dispersion X-ray spectroscopy (FEGSEM-EDS) were utilized as analytical techniques to conjointly to determine the chemical composition of the corresponding materials. The results revealed that the stone used throughout the historic buildings comprises a mixture of calcareous limestone and corallite stones. The associated binding plaster is lime based, made with non-hydraulic lime and local sand, whilst the decorative plaster is made of gypsum (CaSO4). On degraded surfaces it was possible to detect the deposition of sea salt, sulphur and phosphorus as the main atmospheric pollutants and significant contributors to the observed environmental degradation.

Full Text Available Saudi Arabia has witnessed enormous socio-economic changes for the last two decades. Due to this, the standard living of most Saudi people has been improved noticeably. Accordingly, that affects on the consumption expenditure of the Saudi family particularly on the children which has been increased substantially. However, no studies with respect to cost of children have yet been undertaken in Saudi Arabia. This study is to estimate the proportion of expenditure on children, to family’s income in Saudi Arabia by estimating the cost of children in Saudi Arabia; using Jeddah as a case study. In the study, the cost of children is taken to be money expenditure that is the amount that parents actually spent on their children. The study involves a sample of (1500 respondents from the city of Jeddah. Also, explores attitudes and opinions towards certain topics related to cost of children and the family. The study highlights that cost of children rise proportionately to family income, children age, and their numbers.

To assess awareness and attitude of medical students about organ donation. This cross-sectional study was conducted in 2014 at King Abdulaziz University, Jeddah, Saudi Arabia, and comprised medical students. The participants were asked about their religious and other beliefs towards organ donation, their reasons for not donating organs, and their personal opinions about organ donation through a questionnaire. SPSS 21 was used for data analysis. Of the 481 participants, 250(52%) were females, and 231(48%) were males. The overall mean age was 21.36±1.63 years. Besides, 437(90.9%) students knew what organ donation means, 433(90%) supported organ donation, and 90(18.7%) knew someone who had donated an organ. Moreover, 245(50.9%) participants were willing to donate their organ to their family alone, 198(41.2%) were willing to donate to any deserving patient while 439(91.3%) rejected that religion precluded organ donation, and 354(73.6%) did not know about the grafting of organs from a man to a woman and vice versa. Awareness and attitude towards organ donation were not up to the mark among the participants.

Objective: To study the relationship of Vitamin D deficiency and some minerals metabolism in the children with sickle cell disease (SCD) in the city of Jeddah, western region of Saudi Arabia. Methods: A total of 51 children with sickle cell disease (both gender) included 28 males (54.9%) and 23 females (45.1%) aged between newborn and 12 years old and 70 healthy matching controls were admitted or visited sickle cell section in the Maternity and Children Hospital in the city of Jeddah. Fasting blood samples were collected and the serum was separated and stored at -30 deg. C until the time of analysis. Serum 25 (OH) Vitamin D was determined using a commercially available kit (VDBP, Gc globulin), calcium, phosphorus and magnesium were measured using a clinical autoanalyser. Results: The patients were divided into two groups according to the ages, Group-A included 21 patients (both gender) aged between newborn and 6 years, group-B included 30 patients (both gender) aged between 7-12 years. The results obtained showed that the serum concentrations of 25(OH) Vitamin D in both patients groups were significantly lower than the healthy matching controls (P 0.05) and significantly higher in the serum magnesium of group-B (P<0.05). Conclusion: A significant relation between Vitamin D deficiency and children with sickle cell disease which is normal due to confined patients indoor. The serum calcium concentration had no affect in the early stage of ages but a significant lower appeared with increasing of ages. The serum magnesium concentration was higher in group-B which can be explained to the important role of Mg/sup -2/ in the nature of erythrocyte membrane in sickle cell patients. (author)

Full Text Available The Jeddah city is located in a coastal plain area, in the middle of the western side of the Kingdom of Saudi Arabia, bounded by the Red Sea to the west and mountains to the east. Jeddah city receives rainfall runoff from the foothills through different drainage pathways (wadis. During intense rainfall events, runoff flows westward from the hills and mountains towards the Red Sea, causing flash floods in the urban areas along the pathways of these wadis. Two major flash flood events occurred in Jeddah city during 20 November 2009 - January 2011. These events were characterized by rainfall precipitation values of 70 and 111 mm, respectively. Each flash flood event has duration of three hours. The impact of these two flood events have been disastrous causing extensive flooding that killed 113 people in 2009 and damaged infrastructure and property (more than 10,000 homes and 17,000 vehicles. This study deals with the analysis of the different factors that caused these flash flood events. The results indicate that the causes of these floods are related to a number of factors which play as a major contribution to the worsening of the flood disaster. These factors were classified into the following: geomorphological features, anthropogenic activities (urban changes, network and catchment factors, and rainfall and climatic changes factors. The climatic changes have a major impact on the rainfall intensity and will appear more in the future. Other factors related to the wadis tributaries are narrow passes, and high slope of the wadi has additional impacts in the flash floods in the area. The anthropogenic activities include the proliferation of slums and construction in the valleys coupled with the lack of suitable water streams to accommodate the amount of water flowing and the presence of dirt led to the direction of flow.

Problem-based learning (PBL) is the most important educational innovations in the past 4 decades. The objective of the study was to compare between the preference of medical students for PBL and the preference for traditional lectures regarding learning outcomes (e.g., knowledge, attitude, and skills) gained from both methods. A cross-sectional study was conducted among medical students who studied the hybrid curriculum (PBL and traditional lectures) in King Abdulaziz University, Jeddah, in 2011. Data was collected through a pre-constructed, validated, confidentially anonymous, and self-administered questionnaire. Students' perceptions toward PBL and traditional lectures were assessed through their response to 20 statements inquired about both methods of learning using a five-point Likert scale. Descriptive and analytic statistics were performed using SPSS, version 21 (SPSS Inc, Chicago, Ill., USA). Learners preferred PBL more to traditional lectures for better linking the knowledge of basic and clinical sciences (t test=10.15, P .05) was observed regarding the amount of basic knowledge recalled from both methods. Students preferred PBL more to lectures for better learning attitudes, skills, future outcomes, and learning satisfaction (P learn better than lecturing (P traditional lectures for improving most of learning outcome domains, especially, learning attitudes and skills. Introducing hybrid-PBL curriculum in all Saudi universities is highly recommended.

Full Text Available Abstract Background Review of post-operative morbidity reports for pediatric dental care under general anesthesia (GA show great variations. Until now, no morbidity data has been available to estimate the safety of pediatric patients under GA for dental rehabilitation in Saudi Arabia. The purposes of this study were to (1 investigate post-operative complications associated with dental care under GA and (2 correlate morbidity reports with patient's characteristics, dental procedures, and hospital protocol. Methods Study sample included 90 children attending GA for dental treatment at major governmental hospitals in Jeddah. Data were collected from every patient on three occasions, intra-operatively at the operating room, and post-operatively via phone calls in the first and third days after operation. Results Results showed that 99% of the children had one or more complaints in the first day in contrast to only 33% in the third day. Inability to eat (86%, sleepiness (71%, and pain (48% were the most common complaints in the first day, followed by bleeding (40%, drowsiness (39%, sore throat (34%, vomiting (26%, psychological changes (24%, fever (21%, cough (12%, and nausea (8%. A great significant complaints reduction was reported by the third post-operative day. Age, gender, admission type of the patients and GA duration were the factors that showed a significant relationship with post-operative complaints. Conclusion Post-operative morbidity was common, but mostly of mild severity and limited to the first day. Hospital staff efforts should be directed to control commonly reported postoperative complaints.

First Report of Tumor-Like Anomalies on the Copepods and their Seasonality from the Obhur Creek, Jeddah Coast, Central Red Sea

Monthly abundance of the subclass Copepoda was analyzed from the zooplankton samples collected at Obhur Creek, Jeddah, Saudi Arabia during December-2011 till December-2012. Zooplankton samples were collected through surface horizontal tows by a modified WP2 net ( via. mouth diameter 50 cm, length 180 cm, 150 μm mesh size). Order Calanoida dominated the abundance with mean annual average of 75.29%. We observed abnormal protuberances on copepods, known as tumour-like anomalies (TLAs). Calanoida showed more frequent and prominent TLAs on its dorsal surface with highest mean percentage occurring during Jun. 2012 (1.64%). The percentage prevalence of TLAs on the Copepoda was highest during Jun. 2012 (1.36%) and least during Nov. 2012 (0.03%). It is suggested that these TLAs might be caused due to the presence of potentially high levels of toxic substances, which weakens the exoskeleton and thereby making them more susceptible to infections or due to wounds from parasites or might be related to the occurrence of symbiotic tantulocarids or might be due to the radiation stress as a control measure. Whatever the reason, these TLAs have become a serious emerging threat to the aquatic food web. Our investigation is the first of its kind in the coastal waters of the Saudi Red Sea, which needs further investigations in order to elucidate the possible reasons for these abnormalities.

Feasibility of using a subsurface intake for SWRO facility, south of Jeddah, Saudi Arabia

The Kingdom of Saudi Arabia is the largest producer of desalinated water with about 13% of the global desalination capacity. Most of these desalination plants use the open-ocean intakes to deliver raw seawater to the desalination facility. Recently, some of the private desalination plants have shifted to subsurface intake systems, either wells or galleries, in order to obtain better water quality with a minimal environmental impact (e.g. minimal entrainment and impingement). The use of these intake types has improved the raw seawater quality extracted from the Red Sea and Arabian Gulf, providing better protection for the membrane component by eliminating/reducing algae, bacteria and organic matter concentrations from the seawater source. One of these desalination plants is located south of Jeddah city which is the second largest city in Saudi Arabia. The plant shifted from an open-ocean intake to beach wells to improve the water quality at the site. Currently, the plant employs 10 vertical wells to extract enough water to produce 10,000 m3/d of product water via the reverse osmosis process. Studies show that quality of seawater significantly improved after shifting to the well system. The use of a larger capacity well system or a seabed gallery intake was investigated at this site for a proposed additional 20,000 m3/d future expansion of the facility. More than 60 sediment samples were collected from the seabed along five different transects in an area of 25,000 m2, starting from shoreline and moving seaward. Grain size analyses, hydraulic conductivity and mud percentage were analyzed in order to determine the characteristic of marine sediments at the studied site. The marine bottom at the selected site contains carbonate sediments which have a high potential of reducing the natural organic matter concentration in the raw seawater. In this study, the laboratory measurements showed that this site has low mud content and moderately high hydraulic conductivity, which

Malnutrition is a nutritional disorder that adversely affects the body from a functional or clinical perspective. It is very often observed in the elderly population. This study aimed to estimate the prevalence of malnutrition among hospitalized elderly patients and its associated factors and outcomes in terms of length of stay and mortality in King Abdulaziz University Hospital, Jeddah, Saudi Arabia. In a cross-sectional study, we evaluated the nutritional status of hospitalized elderly patients using the most recent version of the short form of Mini Nutritional Assessment (MNA-SF). A total of 248 hospitalized patients were included (70.0 ± 7.7 years; 60% female). According to the MNA-SF, a total of 76.6% patients were either malnourished or at risk of malnutrition. Malnourished patients had significantly lower levels of serum albumin (28.2 ± 7.7), hemoglobin (10.5 ± 1.8), and lymphocyte (1.7 ± 0.91). They had increased tendency to stay in the hospital for longer durations (IQR, 5-11 days; median = 7 days) and had a mortality rate of 6.9%. Malnutrition was highly prevalent among hospitalized elderly and was associated with increased length of stay and mortality.

All 209 congeners of polychlorinated biphenyls (PCBs) in edible fish tissue from the central Red Sea coast (Jeddah region) of Saudi Arabia were analyzed by isotope dilution high-resolution gas chromatography–mass spectrometry. The upper-bound total PCB (ΣPCB) levels in nine commonly consumed fish species from three areas were 0.2–82.5 ng/g wet weight (17–8450 ng/g lipid weight), which were at the lower end of reported global range and far below international tolerance limits (500–3000 ng/g ww). Dioxin-like congeners contributed up to 12.8% (mean 6.5%) to ΣPCB in tissue samples, with the total PCB toxic equivalencies (TEQs) at a tolerable range (0.05–2.6 pg TEQ/g ww or 2–238 pg TEQ/g lw) for all species. PCB profiles were dominated by moderately chlorinated homologs, mainly hexachlorobiphenyls, but less chlorinated congeners were also consistently elevated, notably in Siganus rivulatus (Area III) and Mugil cephalus (Area I). It remains to be ascertained if the latter were breakdown products or due to fresh inputs. The top congeners based on dominance by both occurrence and abundance were identified as potential markers of ΣPCB in fish tissue, which can be used for future selective biomonitoring in case of reasonable constraints on full congener approach.

Deng, Liping

2013-12-01

Modeling flash flood events in arid environments is a difficult but important task that has impacts on both water resource related issues and also emergency management and response. The challenge is often related to adequately describing the precursor intense rainfall events that cause these flood responses, as they are generally poorly simulated and forecast. Jeddah, the second largest city in the Kingdom of Saudi Arabia, has suffered from a number of flash floods over the last decade, following short-intense rainfall events. The research presented here focuses on examining four historic Jeddah flash floods (Nov. 25-26 2009, Dec. 29-30 2010, Jan. 14-15 2011 and Jan. 25-26 2011) and investigates the feasibility of using numerical weather prediction models to achieve a more realistic simulation of these flood-producing rainfall events. The Weather Research and Forecasting (WRF) model (version 3.5) is used to simulate precipitation and meteorological conditions via a high-resolution inner domain (1-km) around Jeddah. A range of different convective closure and microphysics parameterization, together with high-resolution (4-km) sea surface temperature data are employed. Through examining comparisons between the WRF model output and in-situ, radar and satellite data, the characteristics and mechanism producing the extreme rainfall events are discussed and the capacity of the WRF model to accurately forecast these rainstorms is evaluated.

Full Text Available Background: Irritable bowel syndrome (IBS is a highly prevalent gastrointestinal disorder that can cause disability and economic burden. Nurses are a vital part of the medical team and their well-being is an important issue. Yet, few studies have been done concerning IBS among nurses. Objectives: To determine the prevalence, severity, and predictors of IBS among nurses working at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Materials and methods: A cross-sectional study was conducted among 229 nurses who fulfilled the eligibility criteria. They were selected by stratified random sampling during 2014–2015. A validated, confidential, self-administered data collection sheet was used for collection of personal and sociodemographic data. Rome III Criteria, IBS Severity Scoring System (IBS-SSS, Hospital Anxiety and Depression Scale (HADS, and Pittsburgh Sleep Quality Index (PSQI were included. Both descriptive and inferential statistics were done. A multiple logistic regression analysis was done to determine the predictors of IBS. Results: The prevalence of IBS among nurses was 14.4%, and IBS-Mixed type was the commonest variety (54.5%. Positive family history of IBS, working in outpatient clinics, having day shift, poor sleep quality, and high anxiety and depression scale scores were significantly associated with IBS. After controlling for confounding factors in regression analysis, the predictors of IBS were food hypersensitivity (aOR=4.52; 95% CI: 1.80−11.33, morbid anxiety (aOR=4.34; 95% CI: 1.49–12.67, and positive family history of IBS (aOR=3.38; 95% CI: 1.12–13.23. Conclusion: The prevalence of IBS was 14.4%. Food hypersensitivity, morbid anxiety, and family history were the predictors of IBS. Screening and management of IBS, food hypersensitivity, and psychological problems among nurses are recommended.

This paper presents the first comprehensive investigation of PM2.5 and PM10 composition and sources in Saudi Arabia. We conducted a multi-week multiple sites sampling campaign in Jeddah between June and September, 2011, and analyzed samples by XRF. The overall mean mass concentration was 28.4 ± 25.4 μg/m 3 for PM2.5 and 87.3 ± 47.3 μg/m 3 for PM10, with significant temporal and spatial variability. The average ratio of PM2.5/PM10 was 0.33. Chemical composition data were modeled using factor analysis with varimax orthogonal rotation to determine five and four particle source categories contributing significant amount of for PM2.5 and PM10 mass, respectively. In both PM2.5 and PM10 sources were (1) heavy oil combustion characterized by high Ni and V; (2) resuspended soil characterized by high concentrations of Ca, Fe, Al, and Si; and (3) marine aerosol. The two other sources in PM2.5 were (4) Cu/Zn source; (5) traffic source identified by presence of Pb, Br, and Se; while in PM10 it was a mixed industrial source. To estimate the mass contributions of each individual source category, the CAPs mass concentration was regressed against the factor scores. Cumulatively, resuspended soil and oil combustion contributed 77 and 82% mass of PM2.5 and PM10, respectively.

Introduction The levels of physicians' job satisfaction and burnout directly affect their professionalism, punctuality, absenteeism, and ultimately, patients' care. Despite its crucial importance, little is known about professional burnout of the physicians in Saudi Arabia. The objectives of this research are two-fold: (1) To assess the prevalence of burnout in physicians working in primary health care centers under Ministry of Health; and (2) to find the modifiable factors which can decrease the burnout ratio. Methodology Through a cross-sectional study design, a representative sample of the physicians working in primary health care centers (PHCCs) Jeddah (n=246) was randomly selected. The overall burnout level was assessed using the validated abbreviated Maslach burnout inventory (aMBI) questionnaire. It measures the overall burnout prevalence based on three main domains i.e., emotional exhaustion, depersonalization, and personal accomplishment. Independent sample T-test, analysis of variance (ANOVA), and multivariate regression analysis were performed using Statistical Package for the Social Sciences (SPSS Version 22, IBM, Armonk, NY). Results Overall, moderate to high burnout was prevalent in 25.2% of the physicians. Emotional exhaustion was noted in 69.5%. Multivariate regression analysis showed that patient pressure/violence (p burnout. The patient's pressure/violence was the only significant independent predictor of overall burnout. Conclusion Emotional exhaustion is the most prominent feature of overall burnout in the physicians of primary health care centers. The main reasons include patient's pressure/violence, unorganized patient flow, less cooperative colleague doctors, fewer support services at the PHCCs, more paperwork, and less cooperative colleagues. Addressing these issues could lead to a decrease in physician's burnout.

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

Full Text Available Urban soils polluted with heavy metals are of increasing concern because it is greatly affecting human health and the ecological systems. Hence, it is mandatory to understand the reasons behind this pollution and remediate the contaminated solid. The removal of heavy metals from contaminated soil samples collected from the vicinity of the sewage lake in Jeddah, Saudi Arabia, was explored. The leaching process was studied kinetically and thermodynamically for better understanding of the remediation process. The results showed that the soil samples were slightly basic in nature, and tend to be more neutral away from the main contaminated sewage lake area. The total metal content in the soil samples was measured using the aqua regia extractions by ICP-OES and the results showed that many of the heavy metals present have significant concentrations above the tolerable limits. In general, the metal concentrations at different sites indicated that the heavy metal pollution is mainly due to the sewage discharge to the lake. The results showed excellent correlation between the concentrations of Co, As, and Hg with the distance from the main contaminated area. The leaching of Co, As, and Hg using 1.0 M hydrochloric acid from the soil was studied kinetically at different temperatures and the experimental results were fitted using different kinetics models. The experimental data were best described with two-constant rate and Elovich equation kinetic models. Also, the thermodynamic study showed that the leaching process was spontaneous, endothermic and accompanied with increase in the entropy. In general, the polluted soil could be remediated successfully from the heavy metals using the acid leaching procedure in a short period of time.

Full Text Available Background. Saudi women depend on food sources to maintain their serum 25(OH D concentrations because covering by traditional clothing and time spent indoors limit their sun exposure. Little is known about vitamin D intake and its main food sources in Saudi Arabia. In addition, the association between vitamin D and calcium intake and bone mineral density (BMD in young women is not well researched. Objectives. To assess the adequacy of vitamin D intake among Saudi women as compared to the estimated average requirements (EARs, to identify dietary vitamin D sources, to examine potential determinants of vitamin D intake, and to assess bone health and the association of calcium and vitamin D intake with BMD. Methods. This cross-sectional study was conducted in 257 premenopausal women aged 20–50 years in Jeddah, Saudi Arabia. Dietary vitamin D and calcium were assessed by the Semiquantitative Food Frequency Questionnaire. BMD was measured using dual-energy X-ray absorptiometry (DXA in a subset of women n=102 at the lumbar spine and femur neck. Results. Sixty-five percent of women were below the EAR for vitamin D, and 61% fell below the EAR for calcium. Dairy products, supplements, and fish contributed most to vitamin D intake. Increased age was an independent determinant of sufficient vitamin D intake p<0.001. The prevalence of osteopenia was 33% in the lumbar spine and 30% in the femur neck. There was a significant positive association between calcium intake and BMD at the lumbar spine p=0.043 after controlling for body mass index and energy intake. Vitamin D intake was not significantly different between women with low and normal bone mass. Conclusion. Premenopausal women in Jeddah have insufficient vitamin D and calcium intakes. Public health strategies to improve nutrition in young women are needed, and expanding fortification programs to include all dairy products would be useful.

This study determined the prevalence of intestinal parasites, particularly pathogenic Entamoeba sp. (E. histolytica), in patients attending three hospitals in Jeddah City, King Abdulaziz University Hospital, King Abdulaziz Hospital and King Fahad Hospital for gastro-intestinal troubles. 186 stool specimens were examined microscopically for parasites and by ELISA kit (E. histolytica II) for true E. histolytica. 83 samples (44.6%) were positive by microscopy for at least one parasite. Of which, 23 (12.4%) showed two parasites and 15 (8.1%) three parasites. Eight different parasite species were identified. The most prevalent were E. histolytica/dispar (n = 26, 31.3%) and Giardia lamblia (n = 13, 15.7%). Others were Blastocytosis hominis (n = 12, 14.5%), Entamoeba coli (n = 11, 13.3%), Trichuris trichuria (n = 8, 9.6%), Endolymax nana (n = 6, 7.2%), Hymenolepes nana (n = 4, 4.8%) and Chilomastix mesnili (n = 3, 3.6%). Only five stool samples (19%) from those identified by microscopy to contain E. histolytica/dispar, were E. histolytica positive by E. histolytica II ELISA. For the first time to the authors' knowledge the true prevalence of E. histolytica in Saudi Arabia was 2.7%. E. histolytica II ELISA proved to be a highly useful technique to differentiate pathogenic E. histolytica from non pathogenic E. dispar.

This study explored the knowledge and awareness about colorectal cancer (CRC) among undergraduate students of one of the leading universities in Saudi Arabia, along with the mode of information access. The present cross-sectional study was conducted at the King Abdulaziz University, Jeddah, Saudi Arabia, among students of different faculties. The study questionnaire, containing 28 items, was adapted from surveys identified in the relevant literature. The CRC awareness questionnaire consisted of an awareness section (early CRC signs and symptoms, and risk factors) and a knowledge section. The data were analyzed using the SPSS version 21.0. A total of 525 undergraduate students participated in the study. The majority were females (63.0%) and approximately half (56.8%) were medical students. The majority of the students (82.3%) were aware of CRC, and 68% thought that CRC is a preventable disease. Regarding colorectal cancer screening tests, only one-third of students (33%) had actual knowledge, while the majority of the students (77.0%) thought that there are tests which help in early detection. Only 4% of the participants had a family history of CRC. The majority of the participants (84%) thought that CRC is a disease that can be cured. Almost 50-60% participants had good awareness level regarding risk factors, and signs and symptoms. Regarding knowledge, participant responses varied for family history (52%), age (59%), chronic infection of the colon (72%), obesity and lack of exercise (66%). More than one-third of the students had received information material regarding CRC from their curriculum followed by social media (20.4%), and nearly 40% from other sources such as TV, hospital and mass media. Female participants had significantly better awareness in a few questions regarding CRC awareness as compared to their male counterparts. There was a significant difference observed between medical and non-medical students (knowledge about CRC while no significant

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.

Full Text Available Waste-to-energy (WTE is a viable option for municipal solid waste (MSW management and a renewable energy source. MSW is a chronic problem in Saudi Arabia and more specifically in Saudi Urban areas. The MSW practices in KSA are simply done by collecting the waste and dumping it in open landfill sites. KSA is considering WTE as a potential renewable energy source that can contribute to electricity demand in the Kingdom. This research aims to assess potential contribution of WTE facility to meet electricity demand in the three main cities in the Western Province of Saudi Arabia and to provide an alternative solution to landfills. Three scenarios for WTE utilization were developed: Mass Burn, Mass Burn with recycling, and refused derived fuel (RDF with biomethanation. The Mass Burn scenario implies full waste stream incineration; the Mass Burn with recycling scenario considers segregation of reusable materials and the waste leftover for incineration; while RDF with biomethanation considers segregation of general waste stream into inorganic and organic waste and utilizes organic waste for biomethanation and inorganic for RDF. The analyses were completed for Jeddah, Makkah, and Madina cities; with current total population of about 6.3 million. The results show that Jeddah has the potential to produce about 180 MW of electricity based on incineration scenario; about 11.25 MW based on incineration with recycling scenario; and about 87.3 MW based RDF with biomethanation scenario by the year 2032. These values and other two cities values are based on theoretical ideals and they help in identifying the optimal WTE techniques for each city.

We assessed the levels, chemical composition and delineated the sources of PM2.5 in Jeddah, to estimate the anthropogenic influence. Sampling was done from April 8th 2013 to February 18th, 2014 in four cycles. PM2.5 samples were analyzed for black carbon (BC), trace elements (TEs) and water-soluble ionic species (IS). Delineation of sources was by mass reconstruction, enrichment factor (EF), and positive matrix factorization (PMF). The 24-h PM2.5 levels showed seasonal variabilities with mean PM2.5 per cycle (cycle 1: 58.8±25.0, cycle 2: 36.2±12.3, cycle 3: 33.9±9.1, and cycle 4: 38.0±17.7µg/m3) exceeding the WHO guideline (25.0 µg/m3). Overall, BC explained 3.61%, 5.92%, 7.15% and 6.51% of PM2.5 during cycles 1-4, respectively but with delta-C levels below zero. This excluded bio-mass burning as a PM2.5 source. IS were mostly SO42-, NO3-, NH4+, Na+ and K+, characteristic of industrial and vehicular emissions. From mass reconstruction, BC, TEs and IS collectively explained 73.6 - 89.5% of PM2.5. EF analysis defined two broad categories of TEs as; anthropogenic (Ni, V, Cu, Zn, Cl, Pb, S, Lu and Br), and earth-crust derived (Al, Si, Ti, Mg, K, Fe, Sr, Mn, Ca, Na and Cr) TEs. These anthropogenic TEs are mostly of industrial and vehicular origins. PMF broadly defined 4 major sources of PM2.5; fossil fuels combustion (36.0%), soil (34.1%), sea-spray (15.4%) and vehicular emissions (14.5%). Results show a major anthropogenic influence related to vehicular and industrial emissions, and further stress the need for more research to fully delineate PM2.5 sources in Jeddah.

To reduce the incidence of HIV and sexually transmitted infections (STIs), it is necessary to target high-risk populations such as prison inmates. This study aims to explore the range of knowledge on HIV and STIs, sexual behaviors, and adoption of preventive measures among women inmates. This was a survey conducted between July 1, 2012 and July 29, 2012 among women inmates at Briman Prison, Jeddah, Saudi Arabia. The author gave an educational lecture on STIs in a conference room at the prison. Educational material was distributed to the attendees after the lecture, and the survey was conducted one week later. All the participants were asked to complete an anonymous 40-item self-administered questionnaire in the presence of a professional health assistant and a translator, for non-Arabic speakers. Data collected included the personal data of the respondent, her alleged criminal background, penal status, accumulative time in prison, history of smoking, alcohol or drug addiction, knowledge about the seven most common STIs, symptoms, modes of transmission, prevention, sexual activity, addiction, and means of protection. Descriptive analysis was performed using Microsoft Excel. We interviewed 204 women aged 16-60 years (mean, 33.3 years). Most of the respondents (n = 170; 83 · 0%) were not aware of STIs; 117 respondents (57 · 4%) did not undergo screening for STIs before marriage or intercourse, while only 59 (28 · 9%) did. Over half of the respondents (n = 107; 52.5%) thought they knew how to protect themselves from STIs. Nevertheless, 87 (42.6%) were uncertain about the role of condoms in protection from STIs and (n = 41; 20.1%) thought condoms provide 100% protection against STIs, while 72 respondents (35.3%) thought condoms did not confer 100% protection against STIs. Only 10 respondents (4.9%) used condoms to protect themselves from STIs. Saudi women (P = 0.033) and those with a higher level of education (P sexual behaviors

Full Text Available A prominent feature of the architectural style of heritage buildings in western Saudi Arabia (Hijaz cities such as Jeddah is the extensive use in their facades of projected intricately carved wooden bay window (Rowshan sl, Rawasheen pl. Throughout Balad or the old town in Jeddah, the element of Rowshan can be found made from many different types of woods such as teak, Javan, mahogany, other types of african and middle eastern woods and with different sizes, proportions, and varied intricate ornamentations and motifs. Besides its aesthetic value, the rawasheen and their many components and parts provide other functions such as ventilation, lighting, and spatial and visual privacy for building interiors from the outside. The profound degradation of Rawasheen is impacting the authenticity and heritage value of old buildings in historical Jeddah because of many factors that include: extensive moisture damage, using improper repair methods and joinery techniques to maintain rawasheen, using unsuitable cleaning products and wood paints, and replacing damaged parts with unkown types of wood. In order to prevent any further deterioration of Rawasheen, documentation of rawasheen and its components using recent digital methodologies and the utilization of proper repair techniques must be followed when working with these elements to ensure longevity of conservation, and preservation of value and authenticity.Through the disucssion of Rowshan repair methodology that was developed that include the digital documentation of all intricate details of rowshan panels and wood engraving which allowed replicating damaged elements beyond repair and applied to a listed building in old Jeddah, the paper provides Rowshan repair guidelines which relate to documentation, diagnostic methods, investigations and tests, repair methodology and reinforcement.

This study aims to identify the factors associated with domestic violence (DV) among women in Jeddah. Cross-sectional survey. Outpatient departments of three tertiary hospitals in Jeddah. Convenience sample of women, aged 15-70 years, at the outpatient and inpatient clinics. Between 15 December 2011 and 30 May 2012, a psychologist and a professional health assistant explained the purpose of the research to participants, who were then asked to fill a 50-item questionnaire. The questionnaire was created based on questions from three questionnaires: the NorVold Domestic Abuse Questionnaire, the Pregnancy Risk Assessment Monitoring System and the Kansas Marital Satisfaction Scale. The questionnaire was used to assess the association between DV and family status, male partner attitudes, age, educational attainment, employment, financial and socioeconomic status. A total of 2301 women participated in the survey (81% response rate). The mean±SD age of the participants was 34.4±10.9 years. The lifetime prevalence of DV was 34%. Abused women had more children than non-abused women (p=0.001), and their spouses were significantly older than those of non-abused women (p<0.0001). Financially dependent women and those with a high educational status were significantly more likely to report abuse (p=0.003 and p<0.001, respectively). Abused women were also likely to report that their spouse was a smoker (p<0.0001) and had completed at least primary or secondary education (p<0.0001). A significantly lower proportion of abused women reported that their male partners were alcohol users (p=0.001). The results of logistic regression showed that women who were financially dependent had about 1.5-fold odds of being physically abused by a spouse. Many factors are associated with DV against women, thereby highlighting the need to design effective DV prevention programmes.

The hepatotoxicity of Sumithion NP 25/2.5 EC, a new formulated organophosphorous insecticide used in dengue fever vector (Aedes aegypti) control in Jeddah (Saudi Arabia), was studied in albino rats. Both levels of GPT, GOT and ALP, and the combined histological alterations were assessed after treatment. Rats were daily injected intraperitoneally for two and four weeks with 80 and 200 mg/kg of body weight (1/10 and 1/4 of the LD50, respectively). Significant increase in GPT, GOT and ALP levels relative to the increase of treatment dose and duration time was observed. The time factor effect was remarkably noticed in ALP level fluctuation. These results indicate a remarkable defect in the liver functions induced by Sumithion NP 25/2.5 EC. Also, histological alterations in the treated animal's liver were observed including: blood congestion, fatty degeneration, hepatocytes swelling and necrosis. The liver syndrome's intensity correlated with the increase in dose and duration time. The present results could prove the hepatotoxicity of Sumithion NP 25/2.5 EC and its ability to cause severe physiological and histopathological defects in the liver. Therefore, the chemical control of Aedes aegypti must be reduced and other recommended control strategies should be promoted. (author)

Methods: Fatigue was monitored in patients with RA who were already on an adalimumab treatment regimen. Fatigue, general well-being, comorbidities, and disease activity were measured at baseline and ~8, 16, and 24 weeks, thereafter. Results: Significant reductions in fatigue scores and disease activity were observed from baseline to 6 months after. A predictive regression model of fatigue severity was proposed and was found to be significant, with RA disease activity as the most significant predictor of fatigue severity. Conclusion: This quasi-experimental study is a good starting point for research on the efficacy of adalimumab in treating fatigue in RA patients. The results here suggest that a randomized controlled trial assessing adalimumab as a treatment option for RA patients suffering from fatigue is warranted.

Full Text Available Objectives: To determine the prevalence of attention deficit hyperactivity disorder (ADHD, subtypes of ADHD, and psychiatric, academic, and behavioral comorbidity in public primary school students in Jeddah, Saudi Arabia. Methods: This is a cross-sectional study. A simple random sample of 6 primary government schools in Jeddah, Saudi Arabia, was identified (3 male, 3 female, and a random sample of classes in each of grades 1-6 were selected. Between July and November 2016, teachers in these classes were asked to complete the Vanderbilt ADHD scale on all students in their classes. Results: A total of 929 students were screened. The overall prevalence of ADHD was 5% (5.3% in girls, 4.7% in boys. The most prevalent subtype of ADHD was combined type (2.7%, followed by hyperactive type (1.2%, and inattentive type (1.1%. The highest prevalence of ADHD overall was in grade 3 (7.1% and the lowest prevalence in grade 6 (3.4%. Among students with ADHD, prevalence of comorbid psychiatric, academic, and behavioral problems was widespread (56.5% oppositional defiant disorder/conduct disorder, 54.4% impaired academic performance, 44.4% classroom behavioral problems, 41.3% depression/anxiety. Comorbid problems were especially prevalent in combined ADHD subtype and in boys. Conclusions: Attention deficit hyperactivity disorder is common in primary school children in Jeddah, and is associated with widespread psychiatric, academic, and behavioral problems, especially in boys. These findings have implications for the diagnosis and treatment of this serious neurobehavioral disorder.

Large scale patterns of ecologically relevant traits may help identify drivers of their variability and conditions beneficial or adverse to the expression of these traits. Antimicrofouling defenses in scleractinian corals regulate the establishment of the associated biofilm as well as the risks of infection. The Saudi Arabian Red Sea coast features a pronounced thermal and nutritional gradient including regions and seasons with potentially stressful conditions to corals. Assessing the patterns of antimicrofouling defenses across the Red Sea may hint at the susceptibility of corals to global change. We investigated microfouling pressure as well as the relative strength of 2 alternative antimicrofouling defenses (chemical antisettlement activity, mucus release) along the pronounced environmental gradient along the Saudi Arabian Red Sea coast in 2 successive years. Microfouling pressure was exceptionally low along most of the coast but sharply increased at the southernmost sites. Mucus release correlated with temperature. Chemical defense tended to anti-correlate with mucus release. As a result, the combined action of mucus release and chemical antimicrofouling defense seemed to warrant sufficient defense against microbes along the entire coast. In the future, however, we expect enhanced energetic strain on corals when warming and/or eutrophication lead to higher bacterial fouling pressure and a shift towards putatively more costly defense by mucus release.

The aim of this study was to determine the demographic features of erectile dysfunction patients attending different specialized clinics in Jeddah city, and to identify possible risk factors associated with erectile dysfunction problem. All newly erectile dysfunction patients (n=388) who attended 6 andrology and urology clinics within a period of 3 months were subjected to a modified structural interview questionnaire to collect demographic data and risk factors for erectile dysfunction. The study revealed the following results among erectile dysfunction patients; Saudi patients constituted (81%). The age ranged from 20-86 years with mean age of 43.23+12.56 years, 73% were married with one wife, 23.5% married with two wives, and 8% were single. About one-half (43%) were less than secondary education level. Retired patients constituted (13%) of all patients. Lack of exercise was the most frequent risk factor among 82% of patients, followed by smoking (56%), use of regular medication (44%), diabetes (30%), hypertension (15%), history of pelvic surgery (14%) alcoholism (13%), and drug addict (8%). Erectile dysfunction is a problem of not only old age but also of middle and young age. This might be attributed to the high frequency of some risk factors such as diabetes mellitus, hypertension, smoking, alcohol consumption, and drug addiction. This finding may reflect the necessity for construction of prevention strategies.

Seismicity of the Tihamat-Asir region, Kingdom of Saudi Arabia

Knowledge of the seismicity of the west coast of Saudi Arabia is vitally important to the Kingdom. The eastern margin of the Red Sea, which includes all of the west coast of Saudi Arabia, is possibly cut by transform faults that may be capable of producing earthquakes large enough to cause damage in the heavily populated areas or in the industrial complexes under construction. Prior to this study, there were no seismic stations in Saudi Arabia and no studies of microearthquake activity. It was generally assumed that there were no active faults along the west coast. During the period 20 January to 22 February, 1978, five portable seismic stations were deployed in the Tihamat Asir in the southwest part of the country. A significant level of microearthquake activity was detected at a location that approximately coincides with the landward extension of the proposed transform fault. The recording of these earthquakes demonstrates that there are active faults at this location, probably associated with the currently active Red Sea tectonic system. The practical significance of these earthquakes cannot be evaluated from the few data available, and further studies should be undertaken to determine if there are significant seismic hazards along the west coast of Saudi Arabia.

To explore the cultural competence of undergraduate nursing students at a college of nursing, Saudi Arabia. A descriptive exploratory design was used to explore the Saudi undergraduate nursing students' level of cultural competency. The convenience sample included 205 nursing students affiliated with a college of nursing at a health science university in Jeddah, Saudi Arabia. Data was collected using the Inventory for Assessing the Process of Cultural Competence-Revised (IAPCC-R) consisting of 25 items. The tool reported acceptable reliability of Cronbach alpha 0.89. The majority of students were culturally aware and dealt with people from different cultures. One-third preferred to have training on culture over a period of time. Half the students preferred studying a special course related to working with people from different cultures. Cultural desire reported the highest mean while cultural knowledge scored the lowest among the cultural competence subscales despite students being exposed to some cultural knowledge content in their training. Implementing the guidelines for culturally competent care assure covering all aspects of care with consideration of cultural heritage as a main concept. Comparative study of nurses' and students' perception is further recommended. Copyright © 2017 Elsevier Ltd. All rights reserved.

2016-01-01

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

A study was designed to determine the red cell values (hemoglobin and hematocrit) of neonates born in the high altitude of Abha and to compare these values with known values of other lowland areas of Saudi Arabia. From the cord blood of 587 normal, appropriate for gestational age and term infants born in 1993 in Abha Maternity Hospital, the ranges of Hb and Hct were 130 to 240 g/L and 0.24 to 0.79 L/L respectively. The mean Hb was 187 g/L. There was no significant difference between the male and female values. Also, 17% of the infants in this study were polycythemic, while no polycythemia was recorded in these lowland areas and only 2% to 4% in the general global newborn population. It was therefore revealed that Abha newborns had higher red cell values at the birth when compared to other newborns in the low altitude areas of Riyadh and Jeddah (P<0.001). We postulate that high altitude (2700 meters above sea level) of Abha, and therefore its relative hypoxia, has induced high red cell values in infants born in the city. The phenomenon therefore warrants the adoption of higher red cell reference values and not necessarily those already documented in other Saudi new born populations. (author)

Amaranthus pollen grains are known to have highly allergenic and potential cause of respiratory allergic diseases. Nevertheless, data on the prevalence of Amaranthus pollen in the environment is limited and almost non-existent for Saudi Arabia. We conducted an investigation to record the airborne incidence of A.viridis and other allergenic pollen in Al-Khobar, Dammam, Hail, Jeddah, Jizan, Qassim and Taif, using Burkard Volumetric Samplers. The samples were operated continuously for one year at each location. The data revealed A.viridis as one of the major components of outdoor airspora, constituting a maximum of 96% of total pollen counts in Hail, followed by Al-Khobar (89%), Jeddah (87%), Qassim (85%), Taif (84%), Dammam (83%) and Jizan (61%). These higher percentages contributed largely to the total weed pollen catch during August to November in all seven regions. In addition, the data also showed that A. virdis pollen were present throughout the year with distinct seasonal variations. The diel periodicities for at least five sites averaged over a year showed mid-day to early evening maxima. The maximum concentration approached 3000 mt. cube of air in October and 1827 mt. cube of air in September. The data also exhibited, a seasonal pattern, in their maximum appearance. Further studies related to biochemical and allergological aspects are needed to confirm the allergenic impact of Amaranthus pollen and sensitization in allergic individuals in the Kingdom of Saudi Arabia.

Full Text Available The objective of the study was to determine the level of Knowledge, Attitude and Practice (KAP of patients attended dental clinics at King Abdulaziz University Hospital (KAUH regarding cross infections and infection control in dentistry. A cross-sectional study was conducted among 225 patients who attended the dental clinics of KAUH, Jeddah, Saudi Arabia, 2014. A standardized, confidential, anonymous, interviewing questionnaire was used. Knowledge about dental infections was assessed by 12 MCQs. The attitudes were assessed through answering seven statements on a three- point Likert scale. Patients’ self reported practices were also evaluated. Descriptive and inferential statistics were done.Results of the study revealed that 39.5%, 38.7% and 21.8% of the participants obtained poor, fair and satisfactory level of knowledge about infections and infection control in dentistry, respectively. Social media was the commonest source of information about dental infection. Participant's educational level was significantly associated with the level of knowledge about dental infection. Patients had positive attitudes towards infection control in dentistry. Regarding self-reported practice, only few participants would ask dentists about sterilization of dental instruments (9.3%, wearing face mask (13.3% and gloves (16.4% if they don’t do so. In conclusion, our participants had good attitudes towards infection control in dentistry. However, their knowledge and practice need improvements. Conduction of educational programs is needed through social media, mass media, schools and public places. These programs involve both patients and providers.

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

2014-01-01

As sea surface temperatures rise and the global human population increases, large-scale field observations of marine organism health and water quality are increasingly necessary. We investigated the health of corals from the family Fungiidae using visual observations in relation to water quality and microbial biogeochemistry parameters along 1300 km of the Red Sea coast of Saudi Arabia. At large scales, incidence of lesions caused by unidentified etiology showed consistent signs, increasing significantly from the northern to southern coast and positively correlated to annual mean seawater temperatures. Lesion abundance also increased to a maximum of 96% near the populous city of Jeddah. The presence of lesioned corals in the region surrounding Jeddah was strongly correlated with elevated concentrations of ammonium and changes in microbial communities that are linked to decreased water quality. This study suggests that both high seawater temperatures and nutrient pollution may play an indirect role in the formation of lesions on corals. © 2014 Elsevier Ltd.

The annual risk of tuberculosis infection (ARTI) data in Saudi Arabia has not been updated since 1993. To estimate the prevalence of latent TB infection (LTBI) and ARTI in a population-based sample in Saudi Arabia using Tuberculin skin test (TST) and QuantiFERON TB Gold in tube (QFT-GIT) test. A population-based cross sectional study was conducted between July 2010 and March 2013. Participants were randomly selected from the population served by the primary healthcare centers of the Ministry of National Guard Health Affairs in Riyadh, Jeddah, Alhassa and Dammam, Saudi Arabia. A total of 1369 participants were included. The overall prevalence of LTBI was similar using TST and QFT-GIT (9.3% and 9.1% respectively, p=0.872) but stratified prevalence rates were variable in all sociodemographic groups except marital status. Additionally, the prevalence rates of LTBI using either test alone showed significant differences by several sociodemographic and behavioral characteristics. The overall ARTI was 0.36% using TST and 0.35% using QFT-GIT. We are reporting much lower estimates for the prevalence of LTBI and the ARTI in a population-based sample in Saudi Arabia relative to the data that have been used for more than two decades.

Cigarette smoking is one of the leading causes of death in the world. Tobacco consumption has grave negative consequences for health so that it is important to understand the reasons and motivations towards cigarette smoking and barriers against quitting smoking among the young generation for developing effective policies to control this widespread problem. This crosssectional survey was carried out at the Faculty of Medicine, Rabigh, King Abdulaziz University, Jeddah, Saudi Arabia. A total of 438 young smokers participated from the University and the general population. Data were collected through anonymous, selfadministered questionnaires in the Arabic language that contained questions about the reasons and motivations towards cigarette smoking and barriers against quitting smoking. The questionnaire also contained several questions regarding knowledge and attitude of the participants towards cigarette smoking. The data was analyzed on SPSS16. The mean age of the respondents was 22.9±3.48, out of 438 subjects 87 (19.9%) were married, and 351 (80.1%) were unmarried, and 331 (75.6%) belonged to urban areas while 107 (24.5%) were from the rural areas. Responding to a question about a number of cigarettes smoked per day, 31% answered 1120, 29% answered 2130, and 25% answered 110. Questioned about smokers in the family, 34.5% responded more than one, with 19% for brother and 13% for father. About the reasons for not quitting smoking, 26% described lack of willpower, 25% had no reason, 22% said that people around me smoke, and 15.3% responded stress at home/work. The major motivation for smokers was smoker friends (42%), for 33.8% others, for 12% father/brother and 7.8% media. There are several avoidable and preventable reasons and barriers against quitting smoking. However, knowledge and attitude about smoking were good, and the majority of the smokers were well aware of the associated hazards. Therefore, there is a need to search out ways and means to help them to

Full Text Available The sponge Chalinula saudensis, which occurs along the Jeddah coast, has only recently been isolated and identified. In this study, the total crude organic matter of the sponge was extracted by solvents. The total crude extract was further separated by partitioning it with hexane and water, then with water and chloroform, and finally with water and t-butanol. The chloroform layer was subjected to separation by preparative layer chromatography on silica. One fraction contained four long-chain fatty acid esters, C28H56O2, C30H60O2, C32H62O2 and C36H70 O2. The second ester, C30H60O2, has been identified in the fire corals Millepora dichotoma and Millepora platyphylla. The others have not previously been reported from marine organisms; however similar long-chain esters with different long aliphatic chains and with different molecular weights have been identified from other marine organisms. These compounds are normally waxy and their presence in Chalinula saudensis plays a vital role in the biosynthetic pathways. They also act as insulators against seasonal variations.A esponja Chalinula saudensis ocorre ao longo da costa de Jeddah, Arabia Saudita, mas apenas recentemente foi isolada e identificada. No presente estudo a matéria orgânica total da esponja foi extraída por solventes e o extrato foi separado por partição sucessiva através do emprego de hexano e água, clorofórmio e água e finalmente t-butanol e água. A camada contendo clorofórmio foi então separada por cromatografia em sílica. Os resultados mostraram a presença de ésteres de quatro ácidos graxos de cadeira longa (C28H56O2, C30H60O2, C32H62O2 e C36H70O2, sendo que o segundo deles foi também identificado nos corais Millepora dichotoma e Millepora platyphylla. Não se tem evidência da presença dos demais compostos em outros organismos marinhos, embora haja relatos para ésteres semelhantes de cadeia longa, mas contendo diferentes cadeias alifáticas e diferentes pesos

Full Text Available ABSTRACT Background The use of asthma-triggering drugs (ATDs is a major factor in poor asthma control (PAC, which can be either uncontrolled or partially controlled. ATDs include angiotensin-converting enzyme (ACE inhibitors, β-blockers, aspirin, and nonsteroidal anti-inflammatory drugs (NSAIDs. Aims To measure the prevalence of ATD use in adult asthmatics and their control levels. Methods This is a one-year cross-sectional study (starting March 2016. A sample of 173 adult asthmatics (mean age: 44±16 years was enrolled from five primary care centres in Jeddah city (Saudi Arabia. Asthmatics were clinically diagnosed according to the British Thoracic Society’s asthma guidelines. Chronic obstructive pulmonary disease was excluded by reversibility (i.e., symptom improvement after using asthma drugs. The four questions about asthma control from the Global Initiative for Asthma’s 2016 guidelines were translated to Arabic, photos and names of ATDs available in local pharmacies were collected, and a questionnaire was drafted. The questionnaire was presented to adult asthmatics by medical students during a personal interview. Data were statistically analysed using SPSS. Results Fifty percent of the adult asthmatics who used ATDs had badly controlled asthma: 31 per cent uncontrolled and 19 per cent partially controlled. Of the patients who took ATDs, 97 per cent had used several ATDs for extended periods of time without any warnings from health professionals. In order of prevalence, aspirin, ACE inhibitors, other NSAIDs, and β-blockers were the most common ATDs used. Conclusion ATDs are a major cause of PAC. ATD use is extensive and often goes unnoticed. The present findings highlight the low awareness of health professionals about the undesirable effects of ATDs on asthma control. This problem needs to be resolved by regular and continuous asthma health educational courses. During clinic visits, health professionals should inquire about ATD use

Medical profession is a stressful occupation as it carries potential risk for pregnancy outcome. There is lack of researches regarding the pregnancy loss among physicians working in hospitals in Saudi Arabia. The current study aims at estimating the prevalence and factors associated with pregnancy loss among female physicians working at King Abdul-Aziz University Hospital in Jeddah, September, 2015. A cross sectional study has been conducted, which included all the female physicians working at King Abdul-Aziz University Hospital in Jeddah by filling a self-administered online questionnaire. Out of all responding physicians (n = 92), the majority were Saudis (93.5%), who were mostly married (89.1%) and rest were either divorced (8.7%) or widowed (2.2%). Seventeen female physicians had pregnancy loss before (18.5%) with a total of 25 losses, which were mostly occurred during first trimester, especially while working as residents (40%), the average monthly working hours in the first pregnancy loss was (median; IQR, 160, 110-198 h). No statistically significant difference could be detected regarding the variation in pregnancy losses according to nationality marital status nor specialty. Most of the pregnancy losses in physicians occurred in first trimester during residency with a relatively longer monthly working hours. Further researches are needed on a larger sample and wider scale with inclusion of other pertinent factors to enable judging on the independent relationship of pregnancy loss and medical profession.

The aim was to determine the difficulties faced by family physicians, and compare how satisfied those working with the Ministry of Health (MOH) are with their counterparts who work at some selected non-MOH hospitals. An analytical, cross-sectional study was conducted at King Abdulaziz University Hospital, King Faisal Specialist Hospital and Research Center (KFSH and RC), and 40 MOH primary health care centers across Jeddah. A structured multi-item questionnaire was used to collect demographic data and information on the difficulties family physicians face. The physicians' level of satisfaction and how it was affected by the difficulties was assessed. Women constituted 71.9% of the sample. Problems with transportation formed one of the main difficulties encountered by physicians. Compared to non-MOH physician, a significantly higher proportion of MOH physicians reported unavailability of radiology technicians (P = 0.011) and radiologists (P building maintenance (P < 0.001). Family physicians with the MOH were less satisfied with their jobs compared with non-MOH physicians (P = 0.032). MOH family physicians encountered difficulties relating to staff, services, and infrastructure, which consequently affected their level of satisfaction.

Simulation of Flash-Flood-Producing Storm Events in Saudi Arabia Using the Weather Research and Forecasting Model

KAUST Repository

Deng, Liping

2015-05-01

The challenges of monitoring and forecasting flash-flood-producing storm events in data-sparse and arid regions are explored using the Weather Research and Forecasting (WRF) Model (version 3.5) in conjunction with a range of available satellite, in situ, and reanalysis data. Here, we focus on characterizing the initial synoptic features and examining the impact of model parameterization and resolution on the reproduction of a number of flood-producing rainfall events that occurred over the western Saudi Arabian city of Jeddah. Analysis from the European Centre for Medium-Range Weather Forecasts (ECMWF) interim reanalysis (ERA-Interim) data suggests that mesoscale convective systems associated with strong moisture convergence ahead of a trough were the major initial features for the occurrence of these intense rain events. The WRF Model was able to simulate the heavy rainfall, with driving convective processes well characterized by a high-resolution cloud-resolving model. The use of higher (1 km vs 5 km) resolution along the Jeddah coastline favors the simulation of local convective systems and adds value to the simulation of heavy rainfall, especially for deep-convection-related extreme values. At the 5-km resolution, corresponding to an intermediate study domain, simulation without a cumulus scheme led to the formation of deeper convective systems and enhanced rainfall around Jeddah, illustrating the need for careful model scheme selection in this transition resolution. In analysis of multiple nested WRF simulations (25, 5, and 1 km), localized volume and intensity of heavy rainfall together with the duration of rainstorms within the Jeddah catchment area were captured reasonably well, although there was evidence of some displacements of rainstorm events.

The present study explored the utility, attitude, and trends regarding Smartphone related Medical Applications (Apps) among medical students of King Abdulaziz University (KAU) Jeddah, Saudi Arabia (SA) and their perceptions of the impact of Medical Apps in their training activities. This survey was conducted at the Faculty of Medicine, Jeddah, and Rabigh campuses, KAU, Jeddah, SA. All participants were medical students of 2nd to 6th year. The data was collected by using an anonymous questionnaire regarding the perception of medical students about Medical Apps on the smart devices and the purpose of installation of the Apps. Additionally examined was the use of different Medical Apps by the students to investigate the impact of Medical Apps on the clinical training/practice. Data was analyzed on SPSS 21. The opinion of 330/460 medical students from all academic years was included in the study with a response rate of 72%. There were 170 (51.5%) males and 160 (48.5%) females with a mean age of 21.26±1.86 years. Almost all participating students 320 (97%) were well aware of Medical Apps for smart devices and 89.1% had installed different applications on their smart devices. The main usage was for either revision of courses (62.4%) or for looking up of medical information (67.3%), followed by preparing for a presentation (34.5%) and getting the medical news (32.1%). Regarding the impact of Medical Apps, most of the students considered these helpful in clinical decision-making, assisting in differential diagnosis, allowing faster access to Evidence-Based Medical practice, saving time and others. The practical use of these Apps was found to be minimal in medical students. Around 73% were occasional users of Medical Apps, and only 27% were using Medical Apps at least once a day. The regular use of Medical Apps on mobile devices is not common among medical students of KAU. Copyright © 2016 King Saud Bin Abdulaziz University for Health Sciences. Published by Elsevier Ltd

Impact of well intake systems on bacterial, algae, and organic carbon reduction in SWRO desalination systems, SAWACO, Jeddah, Saudi Arabia

KAUST Repository

Dehwah, Abdullah

2014-07-18

The intake system can play a significant role in improving the feed water quality and ultimately influence the performance of downstream components of the seawater reverse osmosis desalination processes. In most cases, open-ocean intakes produce poor feed water quality in terms of the abundance of naturally occurring organic matter, which increases the risk of membrane fouling. An alternative intake is the subsurface system, which is based on the riverbank filtration concept that provides natural filtration and biological treatment of the feed water prior to the entry of the water into the desalination plant. The use of subsurface intakes normally improves the raw water quality by reducing suspended solids, algae, bacterial, and dissolved organic carbon concentrations. Therefore, the risk of biofouling caused by these substances can be reduced by implementing the appropriate type of intake system. The use of well intake systems was investigated along the Red Sea shoreline of Saudi Arabia in the Jeddah region. Data were collected from a seawater reverse osmosis (SWRO) plant with a capacity of 10,000 m3/d. The well system produces feed water from an artificial-fill peninsula that was constructed atop of the seabed. Ten wells have been constructed on the peninsula for extracting raw seawater. Water samples were collected from nearby surface seawater as a reference and from selected individual wells. The percentage of algae and bacterial removal by induced filtration process was evaluated by comparison of the seawater concentrations with the well discharges. Transparent exopolymer particles and organic carbon fractions reduction was also measured. The quality of raw water extracted from the well systems was highly improved compared with the raw seawater source. It was observed that algae were virtually 100% removed and the bacterial concentration was significantly removed by the aquifer matrix. The detailed analysis of organic carbon fraction using liquid

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. © 2014 Elsevier Inc.

Peeling skin syndrome (PSS) is a rare genodermatoses of probable autosomal recessive inheritance in Saudi Arabia, consanguinity of parents is common and consequently the occurrence of family disease, including that of the skin, is not uncommon. To characterize the clinical and pathological features of PSS in Saudi Arabia, we reviewed the medical records and clinical photographs of patients with recurring blistering diseases and conducted a histopathologic evaluation of skin biopsies to identify the site of cleavage. Eleven persons with PSS were seen at King Khalid National Guard Hospital in Jeddah between the years 1986 and 2005. Ages ranged between 2 and 15 years and there were 9 males (81.8%) and 2 females (18.2%). The most common presentation in the majority of patients was localized spontaneous peeling of the skin. Eight patients (72.8%) had a history of vesicles that were small, dry and peeled away. Trauma did no play role in blister formation. All patients were local from Bedouin tribes where a family history of a similar complaint was documented in 8 cases (72.7%). And consanguinity of marriage was evident on 6 patients (54.5%). Histological examination of the biopsies showed either intracorneal or superficial subcorneal cleavage above the granuler layer in all biopsied patients. Although rare, PSS occurs in Saudi Arabia and is most likely related to consanguinity of marriages. This disease is generally mild and is characterized by intrascorneal cleavage within the superficial epidermis. The disease should be recognized and not confused with other vasicobullous disease.

Coral-associated bacteria play an increasingly recognized part in coral health. We investigated the effect of local anthropogenic impacts on coral microbial communities on reefs near Jeddah, the largest city on the Saudi Arabian coast of the central Red Sea. We analyzed the bacterial community structure of water and corals (Pocillopora verrucosa and Acropora hemprichii) at sites that were relatively unimpacted, exposed to sedimentation & local sewage, or in the discharge area of municipal wastewaters. Coral microbial communities were significantly different at impacted sites: in both corals the main symbiotic taxon decreased in abundance. In contrast, opportunistic bacterial families, such as e.g. Vibrionaceae and Rhodobacteraceae, were more abundant in corals at impacted sites. In conclusion, microbial community response revealed a measurable footprint of anthropogenic impacts to coral ecosystems close to Jeddah, even though the corals appeared visually healthy.

The V World Youth Championship for FIFA Cup was held for the first time in Saudi Arabia from 16-2-89 till 3-3-89. Sports injuries at this competitions was reported from the city of Jeddah, Saudi Arabia with eight matches taking place at different days. Out of 176 soccer players from group C (Brazil, Germany DR, Mali and USA) who participated in this competition, only six were injured and 7 injuries were noted with an incidence of 3.98% (n = 7/176). Lower limb injuries predominated (ankle sprain: 28.57%; tibia fracture: 14.29%), whereas head, facial, radius and rib injuries had equal rates (14.29%). Also, fractures predominated (42.86%) due to the aggressive attitudes. Concussion (14.29%) and cut wound (14.29%) were less common. High skills, good physical fitness, compliance of rules and regulations, strict surveillance of violence and misbehaviour by the FIFA cup organizing team and allied offices led to the well performance, safer environment and low incidence of sports injuries.

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.

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

Although vaginismus is a common sexual dysfunction in Saudi Arabia, there are limited data concerning the treatment modalities associated with patients with symptoms of vaginismus. This study is aimed to evaluate the presentation and different modalities of management in patients with severe refractory vaginismus in western Saudi Arabia. Successful penetrative sexual intercourse suggesting that common elements of the therapies used were successful. A retrospective study of patients presenting with severe refractory vaginismus treated in Jeddah, Saudi Arabia. The subjects were 15 women with third to fourth degree vaginismus who presented to King Abdulazziz University Hospital between January 1, 2008 and January 1, 2009. The mean age of the participants was 23 years. The mean duration of marriage before seeking medical advice was 12 months. Six patients had undergone conventional therapy successfully. The other six cases, four of which had a previous history of treatment failure, and two who were unresponsive to 4 months of conventional therapy were offered botulinum toxin type A. Five patients who received the Botox therapy had satisfactory intercourse on the same day of the treatment. One patient required a repeat injection after 2 months for recurrent vaginismus. Three of the 15 patients refused the treatment as they were already divorced and had only come in to exclude organic causes for their condition. Vaginismus is an overlooked topic in conservative societies such as Saudi Arabia. For most patients, not knowing who to confide in or where to turn to plays a major role in the under diagnosis of vaginismus. Conventional therapy proved effective in mild and moderate cases, while botulinum toxin has a more rapid effect and was thus more effective in severe cases. © 2011 International Society for Sexual Medicine.

To observe the pattern of inflammatory bowel diseases (IBD) among the people of Western region of Saudi Arabia, and to correlate the findings with published data. This is a retrospective study. All colonic biopsies were reviewed which were received, and processed at the Histopathology Department of King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia, from January 2002 to July 2007. Ethical approval was obtained from the Bioethical and Research Committee. There were 711 colonic biopsies received during this period. One hundred and twenty-two patients were diagnosed with ulcerative colitis (UC). There were 65 males and 57 females. The age ranged between 4-73 years. Most of the UC patients presented in adolescence, and in the adult age. Crohn's disease (CD) was diagnosed in 15 patients, 7 males and 8 females. The age ranged from 1-40 years. Most of the cases were seen in the adult age group. We conclude that IBD is certainly one of the major serious colonic lesions in our society, which should be thoroughly investigated by the combined efforts of clinicians and pathologists. We also conclude that gastrointestinal tuberculosis and infective colitis should always be investigated before suggesting the specific diagnosis of IBD. We recommend a broad based epidemiological study, simultaneously involving clinicians, and pathologists, to document the characteristics of this disease in our society. (author)

Full Text Available The Arabian Gulf is considered as one of the most important sources for the crude oil all over the world. Due to the vast oil exploration and exploitation, huge amounts of organic pollutants infiltrate to the gulf. An important class of organic pollutants is polycyclic aromatic hydrocarbons (PAHs. One of the marine habitats in Arabian Gulf area is the mangrove stands, that are undoubtedly impacted by all anthropogenic factors like oil industries and sewage discharge. In the monitoring framework for mangrove ecosystem along Saudi coasts, nine mangrove stands were examined for the accumulation of PAHs in the Arabian Gulf coast. PAHs were measured using Gas Chromatography-Mass Spectrometry. The mean values detected for total PAHs in mangrove sediments, roots and leaf were 105.39, 680.0 and 282.4 ng/g, respectively. The trend of total PAHs concentrations in all sites showed the descending order: roots > leaf > sediments. Despite the sandy nature and low organic carbon contents of the mangrove sediments, moderate values of PAHs were detected in the major sites. PAH bio-accumulation factors for roots are higher than that in leaf. The diagnostic ratios revealed that the sources of PAHs are mainly pyrogenic, except for Damam and Damam Port that were found to be petrogenic.

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. 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. 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 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 intake of breakfast, vegetables and fruit. Physical activity had a significant (p intake but not with sedentary behaviors. The high prevalence of sedentary behaviors, physical inactivity and unhealthy dietary habits among Saudi adolescents is a major public health concern. There is an urgent need for national policy promoting active living and healthy eating and reducing sedentary behaviors among

Persons with colon cancer experience considerable psychological stress due to physical and social changes brought on by illness, increasing their risk of depressive disorder (DD). We examine the prevalence of DD and depressive symptoms and determine baseline demographic, social, psychological, and physical health correlates. A convenience sample of 70 cancer patients in Jeddah, Saudi Arabia, was screened for DD using an abbreviated version of the Structured Clinical Interview for Depression (SCID) and for depressive symptoms using the Hamilton Depression Rating Scale (HDRS). Demographic, psychosocial, psychiatric, and physical health characteristics were also assessed, along with past treatments for colon cancer. Bivariate and multivariate analyses identified predictors of DD and symptoms. The 1-month prevalence of DD was 30.0% (12.9% major depression, 5.7% minor depression, and 11.4% for dysthymia) and significant depressive symptoms were present in 57.1% (HDRS 8 or higher), including having persistent suicidal thoughts for 2 weeks or longer wthin the past month (14.3%) . Low social support and having a co-morbid psychiatric illness (particularly anxiety) independently predicted DD based on the SCID. Saudi nationality, poor financial situation, low social support, and co-morbid psychiatric illness independently predicted depressive symptoms on the HDRS. Surprisingly, stage of cancer, duration of cancer, and treatments for cancer were unrelated to DD or depressive symptoms. DD and significant depressive symptoms are common in patients with colon cancer in Saudi Arabia, and are predicted by a distinct set of demographic and psychosocial risk factors that may help with identification. Demographic and psychological risk factors were more likely to be associated with depression than cancer characteristics in this sample. Copyright © 2014 John Wiley & Sons, Ltd.

Full Text Available The study investigated the academic literacy socialization of students at U.S. universities from the Gulf Region—Oman, Saudi Arabia, and United Arab Emirates (UAE. International students were contacted and asked if they would participate in the project. Fifty three students responded to the survey and interview, 77% of the respondents were  male and 23% were female. The results of the study found that the Gulf Coast students studying in the U.S. shared similar experiences in how they socialized academically, however, noticeable differences appeared between linguistic abilities and grammar challenges. When the students were asked if their linguistic abilities prevented them from participating in classroom discussion, the Saudi participants were the only group that said ‘Never’. Likewise, when the researchers inquired about grammar challenges, an interesting dissimilarity revealed itself. The Saudi sample indicated it was very easy while the UAE participants specified that it was somewhat difficult and each group had the same percentage of respondents. Although differences between the students were observed, similarities were also revealed. For instance, all the students did not mind working academically with the opposite sex. The results of this study help in the understanding on how to help students from the Gulf Coast academically assimilate into the American educational system.

Drug safety has major implications for patients' lives. However, this concept is still considered new to some healthcare professionals. This study aims to investigate the knowledge and awareness of Saudi healthcare professionals to pharmacovigilance (PV). Setting Governmental and private hospitals at three main cities in Saudi Arabia (Riyadh, Jeddah, and Dammam). A cross-sectional survey among healthcare professionals (pharmacists, physicians, and nurses) within 12 Saudi hospitals was conducted between November and December 2012. The questionnaire consisted of 18 questions assessing the knowledge, awareness, and attitude of healthcare professionals (HCPs) towards science and the concept of PV. Descriptive statistics were used to analyze the data. The data were analyzed using Statistical Analysis Software (SAS 9.3). Main outcome measure Knowledge, attitude and practice of HCPs toward pharmacovigilance. Three-hundred and thirty-two healthcare professionals completed the survey (response rate 72 %), 110 (34 %) physicians, 106 (33 %) pharmacists, and 104 (32 %) nurses. More than half of the participants (55 %) did not know the correct definition of PV. Two-thirds of the respondents, 207 (65.5 %), had knowledge of the aim of post-marketing surveillance, yet only 113 (36.9 %) were aware that the National Pharmacovigilance and Drug Safety Center is the official body for monitoring adverse drug reaction in Saudi Arabia. In addition, 34.7 % agreed that lack of time could be a major barrier for reporting. The majority of the respondents (78.4 %) believed that reporting was a professional obligation and hospitals should have a drug safety department. There was a limited knowledge of pharmacovigilance that could have affected reporting incidence. Educational intervention and a practical training program need to be applied by the drug regulatory body as well as health authorities to enhance the pharmacovigilance and drug safety culture in Saudi Arabia.

Favorable conditions to tropospheric ozone (O3) formation are present over the Persian Gulf Region. Ozone is a well known pollutant affecting human health and natural ecosystems. Among the several factors contributing to the formation of the O3 hot spot over the Middle East, the presence of local emissions of its precursors needs to be considered. We report initial measurements of a suite of nonmethane hydrocarbons (NMHCs), an important component of volatile organic compounds (VOCs), which, coupled with nitrogen oxides in the presence of sunlight, are key chemical precursors of tropospheric O3. We measured 63 speciated C2-C10 NMHCs, in addition to methane (CH4) and carbon monoxide (CO) in three cities of Saudi Arabia (Jeddah, Mecca, and Madina; October-November 2012 and April 2013) and in the city of Lahore (Pakistan; December 2012). To put these data into perspective, we compare our results to data collected in Singapore (August-November 2012). We observed enhanced levels in all three Saudi Arabian cities compared to the local background and to those measured in Singapore. However, the Saudi levels are much lower than those measured in Lahore, where the sum of quantified NMHCs is about six times higher. For Madina, enhanced levels of the alkenes, ethyne and CO indicated that vehicle exhaust was the dominant source. In Jeddah and Mecca, the most abundant NMHC were the alkanes (47-61% of total measured NMHCs), which are more closely associated with emissions from natural gas, liquid petroleum gas (LPG), and gasoline evaporation. In Lahore, the hydroxyl radical (OH) reactivity, used to evaluate the importance of the different measured species toward ozone production, is three to six times higher than for the Saudi cities, and more than 20 times higher than for Singapore. For all urban areas reported here, among the measured compounds, the alkenes (especially ethene and propene) dominate in terms of OH reactivity because of a combination of their great abundance and

In this work we use geophysical methods to locate and characterize active faults in alluvial sediments. Since only subtle material and velocity contrasts are expected across the faults, we used seismic refraction tomography and 2D resistivity imaging to locate the fault. One seismic profile and one 2D resistivity profile are collected at an alluvial fan on the Gulf of Aqaba coast in Saudi Arabia. The collected data are inverted to generate the traveltime tomogram and the electric resistivity tomogram (ERT). A low velocity anomaly is shown on the traveltime tomogram indicates the colluvial wedge associated with the fault. The location of the fault is shown on the ERT as a vertical high resistivity anomaly.

Full Text Available The Saudi Commission for Health Specialties first implemented the Objective Structured Clinical Examinations (OSCE as part of the final year Internal Medicine clerkship exam during the 2007–2008 academic year. This study evaluated Internal Medicine residents׳ overall perceptions of the OSCE as a formative assessment tool. It focused on residents׳ perceptions of the OSCE stations׳ attributes, determined the acceptability of the process, and provided feedback to enhance further development of the assessment tool. The main objective was to assess Internal Medicine resident test-takers׳ perceptions and acceptance of the OSCE, and to identify its strengths and weaknesses through their feedback. Sixty six residents were involved in the studied administered on November 8th 2012 at King Abdulaziz University Hospital in Jeddah, Kingdom of Saudi Arabia. Overall, resident׳s evaluation of the OSCE was favorable and encouraging. To this end, we recommend that formative assessment opportunities using the OSCE for providing feedback to students should be included in the curriculum, and continuing refinement and localized adaptation of OSCEs in use should be pursued by course directors and assessment personnel.

ABSTRACT The nutrition transition with associated lifestyle-related non-communicable diseases has rapidly reached many developing countries, including Saudi Arabia. Therefore, the objective of this study was to examine the prevalence of overweight, obesity, and abdominal obesity among Saudi adolescents. This school-based multicentre cross-sectional study was conducted during 2009-2010 in three major cities in Saudi Arabia: Al-Khobar, Jeddah, and Riyadh. Participants included 2,908 students of secondary schools (1,401 males and 1,507 females) aged 14 to 19 years, randomly selected using a multistage stratified cluster-sampling technique. Weight, height, and waist-circumference were measured; prevalence of overweight and obesity was determined using age- and sex-specific BMI cutoff reference standards of the International Obesity Task Force (IOTF). Abdominal obesity was determined using waist-to-height ratio (WHtR) cutoffs (above 0.5). The prevalence of overweight was 19.5% in males and 20.8% in females while that of obesity was 24.1% in males and 14% in females. The prevalence of abdominal obesity in males and females was 35.9% and 30.3% respectively. Higher prevalence of obesity was observed among adolescents in private schools. Across all ages, overweight and obesity ranged from 39.9% to 45.6% in males and from 30.4% to 38.7% in females. ANCOVA, controlling for age, showed significant interaction effects (city by gender). It is concluded that the proportions of overweight, obesity, and abdominal obesity, observed among Saudi adolescents were remarkably high. Such high prevalence of overweight and obesity is a major public-health concern. PMID:25895197

The various factors that may contribute to vitamin D deficiency or insufficiency were examined among healthy Saudi pre- and postmenopausal women. Vitamin D deficiency was highly prevalent among studied Saudi women with obesity, poor sunlight exposure, poor dietary vitamin D supplementation and age as the main risk factors. The various factors that may contribute to vitamin D deficiency or insufficiency in relation to bone health among Saudi women are not known. The main objectives of the present study were to determine the factors influencing vitamin D status in relation to serum 25-hydroxyvitamin D (25(OH)D), intact parathyroid hormone (PTH), bone turnover markers (BTMs), bone mineral density (BMD), and vitamin D receptor genotype (VDR) in healthy Saudi pre- and postmenopausal women. A total number of 1,172 healthy Saudi women living in the Jeddah area were randomly selected and studied. Anthropometric parameters, socioeconomic status, sun exposure index together with serum levels of 25(OH)D, calcitriol, intact PTH, Ca, PO4, Mg, creatinine, albumin, and biochemical BTMs were measured. BMD was measured by a dual energy X-ray absorptiometry and VDR genotypes were also determined. About 80.0% of Saudi women studied exhibited vitamin D deficiency (serum 25(OH)D75 nmol/L). Secondary hyperparathyroidism was evident in 18.5% and 24.6% in pre- and postmenopausal women with 25(OH)Dobesity, poor exposure to sunlight, poor dietary vitamin D supplementation, and age.

Iron deficiency anaemia is one of most prevalent nutritional disorders worldwide. It is known to affect the health and cognitive ability of children and adolescents. Studies in Saudi Arabia concentrate only on the population of young children and pregnant females or girls. Studies on the whole school student population is lacking. The objectives of this study were to identify the nutritional habits and the prevalence of anaemia among school students in Jeddah, as well as to recognize the students' awareness of their anaemic nutritional status. Data were collected from a sample of Saudi school children in Jeddah City from 42 boys' and 42 girls' schools during the month of April 2000. Data collection was done by an in-person interview to collect socio-demographic factors, nutritional habits, weight and height. Haemoglobin was measured in a sample of 800 students selected at random from both genders and different age groups. Anaemia was defined according to the new WHO cut-off levels for haemoglobin as: blood haemoglobin breakfast was reported by 14.9% of students and this habit did not differ by age, sex, body mass index or social class. Skipping breakfast was more marked among students with poor school performance as compared to those with very good or excellent results. Only 34.1% of anaemic school students were aware of being anaemic. Awareness was nearly equal in all age groups and social classes but girls were more aware of their anaemic status than boys. Iron deficiency anaemia appears to be prevalent among school students. At age 12 years and over, low social class and menstruating girls constitute the high-risk groups. Screening is recommended for high-risk groups and school health programs are crucial to improve students' nutritional habits, knowledge and awareness.

This study assesses the presence of microplastic litter in the contents of the gastrointestinal tract of 26 commercial and non-commercial fish species from four difference habitats sampled along the Saudi Arabian coast of the Red Sea. A total of 178 individual were examined for microplastics. In total, 26 microplastic fragments were found. Of these, 16 being films (61.5%) and 10 being fishing thread (38.5%). FTIR analysis revealed that the most abundant polymers were polypropylene and polyethylene. The grouper (Epinephelus spp.) sampled at Jazan registered the highest number of ingested microplastics. This fish species is benthic and feeds on benthic invertebrates. Although differences in the abundance of microplastic ingestion among species were not statistically significant, a significant change was observed when the level of ingestion of microplastics particles was compared among the habitats. The higher abundance of microplastics particles may be related to the habitats of fish and the presence of microplastics debris near the seabed. The results of this study represent a first evidence that microplastic pollution represents an emerging threat to Red Sea fishes, their food web and human consumers.

Objective. The aim of this cross-sectional study was to investigate the prevalence of dental anomalies that could be a cause of malocclusion in the western region of Saudi Arabia. Materials and Methods. A retrospective study of 878 digital orthopantomograms (OPGs) taken of patients, age ranging between 12 and 30 years, who presented to treatment at the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia between 2002 and 2011. The OPGs and dental records were reviewed for congenitally missing teeth, supernumerary teeth, impactions, ectopic eruption, transposition, germination, fusion, dilacerations, taurodontism, dens in dent, and any other unusual conditions that can be assessed with OPG. Results. The prevalence of patient that exhibited at least one dental anomaly was 396 (45.1%) patients. The prevalence of congenitally missing teeth was 226 (25.7%), impacted teeth 186 (21.1%), dilacerated teeth 10 (1.1%), supernumerary teeth 3 (0.3%), odontoma 1 (0.1%), and taurodontism was also 1 case (0.1%) of the total radiographs reviewed. Conclusions. Congenitally missing teeth were found to be the most prevalent anomaly (25.7%), and the second frequent anomaly was impacted teeth (21.1%), whereas root dilacerations, supernumerary teeth, and taurodontism were the least frequent anomalies (1.1%, 0.3% and 0.1%, resp.).

Multiple surveys of medical residents have shown a high incidence of harassment and discrimination in academic health centers. Harassment has a negative effects on residents' health and on their ability to function. No previous study has documented the prevalence of harassment and discrimination among residents in Saudi Arabia. We aimed in this study to assess the prevalence of harassment and discrimination among residents at a tertiary care academic hospitals in Saudi Arabia. Cross-sectional survey conducted at National Guard Hospitals in Riyadh, Jeddah and Al-Ahsa'a from 27 July to 20 August 2010. The survey included questions on the prevalence of harassment of different types, inlcuding verbal, academic, physical and sexual harassment, as well as discrimination on the basis of gender, region of origin or physical appearance. Of 380 residents, 213 (56%) returned a completed questionnaire (123 male, 57.8%). At least one of type of harassment and discrimination was reported by 83.6% of respondents. The most frequently reported forms were verbal harassment and gender discrimination (61.5% and 58.3%, respectively). Sexual harassment was commonly reported (19.3%) and was experienced significantly more often by female residents than by male residents (P=.0061). Harassment and discrimination of Saudi residents is common with more than three-quarters reporting having had such an experience. Identification of the risk factors is a necessary first step in clarifying this issue and could be used when planning strategies for prevention.

Chromosomal instability (CIN) is a feature of human neoplasm. The p53 mutation has been shown to be associated with CIN in many human dysplastic and neoplastic lesions. The objective of this study was to examine CIN and p53 mutations in prostate carcinoma (Pca) resected from Saudi patients. Testing of p53 alterations using immunohistochemistry was performed on 28 archived prostatic carcinoma specimens containing Pca foci from Saudi patients seen at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia. Chrosomal instability was evaluated in the same tissues by interphase in situ hybridization (IFISH) using centromere probes for chromosomes 7 and 8. Immunochemistry and IFISH were performed at Princess Margaret Hospital, University Health Network, Toronto, Ontario, Canada in 2001. The p53 immunoreactivity was found in 29% in Pca and 0% in benign epithelium. Interphase in situ hybridization revealed numerical chromosomal alterations in keeping with CIN in 63% of p53 positive and 20% p53 negative Pca. No evidence of CIN was seen in non-neoplastic epithelium. We concluded that CIN as determined by IFISH is present in Pca from Saudi patients similarly to those reported in western countries. The p53 mutation occurs relatively infrequently in Pca and associated with the presence of CIN at least in a subset of Pca. (author)

To assess knowledge regarding the management of odontogenic infections by dentists in Jeddah, Kingdom of Saudi Arabia. In this cross-sectional study, 150 practitioners responded to a 26-item paper-based questionnaire between August and December 2014. The questionnaire evaluated knowledge and current clinical practices in managing odontogenic infections, as well as the attitude towards antibiotic use and resistance in the community. Basic medical knowledge (BMK) and critical knowledge (CK) scores were calculated from the dentists' response to these questions and were compared according to educational level (bachelor and postgraduate degree holders). The mean BMK score was 1.98 ± 0.4 and CK score was 1.89 ± 0.3. Dentists with bachelor's degrees had higher BMK scores than those with a postgraduate degree (p=0.005), but CK was not significantly different (p=0.400). Most dentists (77%) would prescribe antibiotics after a routine dental extraction, and would undertake definitive surgical treatment (49.2%) only after a localized space infection developed. Although 82.2% agreed that routine prescription of antibiotics increases bacterial resistance in the community, 71% believe that prescribing an antibiotic after routine oral surgical procedures prevents odontogenic infections. Dentists in Jeddah require further education through lectures and workshops to stay up to date on current concepts in odontogenic infection management.

Full Text Available To evaluate the prevalence, etiologic factors and therapy of hypertension in actively followed up transplant population in Saudi Arabia; we retrospectively reviewed the records of the active renal transplant patients at two large transplant centers in Riyadh and Jeddah in Saudi Arabia. These subjects were transplanted between January 1979 and November 1998. The patients were grouped according to the measurement of blood pressure; group 1 (considered normo-tensive: blood pressure below 140/90 mmHg, group2: blood pressure between 140-159/90-99, group 3: blood pressure 160-179/100-109 group 4: equal to or above 180/110. There were 1115 patients′ records included in the study. The mean duration of transplantation was 66.9 ± 50.1 months. According to the level of measured blood pressure, there were 641 (57.5% patients in the normotensive group (group 1, 404 (36.3% patients in the mildly hypertensive group (group 2 64 (5.7% patients in the moderately severe hypertension group (group 3 and only six (0.5% patients in the severe hypertension group (group 4. The estimated prevalence of hypertension in this study was almost 85%. We found no significant difference in the prevalence of hypertension in terms of gender, year of transplantation, duration of transplantation, type of donor, number of previous transplants, diagnosis of renal artery stenosis, etiology of kidney disease, diagnosis of diabetes after transplantation, diagnosis of cerebrovascular accidents, or mean dose of prednisolone and cyclosporine. There was a statistically significant association between increased level of blood pressure and old age (above 50 years, original disease associated with hypertension, history of hypertension on dialysis, acute rejection (once or more, presence of protienuria (more than 0.3 mg/day, abnormality of ECG, or serum creatinine above 300 µmol/L.

There is a need for comprehensive studies on adolescents' sleep habits in the Middle Eastern region. The aim of this study was to investigate the sleep-wake patterns, prevalence of excessive daytime sleepiness (EDS), and disturbed sleep among adolescents in Saudi Arabia and to identify the associated factors. The study was a cross-sectional survey done on a random sample of 1035 high school students, ages 14-23 years, in Jeddah, Saudi Arabia. The response rate was 91%. Students filled a self-reported questionnaire that included sleep-wake questions, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Perceived Stress Scale, academic performance, and personal data. Students slept an average of 7.0 hours on school nights, with an average delay of 2.8 and 6.0 hours in weekend sleep and rise times, respectively. Around 1 in 10 students stayed up all night and slept after returning from school (exhibiting a reversed sleep cycle) on weeknights. This pattern was more prevalent among boys and students with lower grade point averages. The prevalence of sleep disturbance was 65%, and EDS was found in 37% of the students. Predictors of EDS were school type, stress, napping and caffeine use, while gender was a predictor of disturbed sleep. Adolescents in Saudi Arabia showed a high percentage of poor sleep quality. Compared with adolescents from other countries, they had a larger delay in weekend sleep and rise times. An alarming reversed sleep cycle on weekdays is present and highlights the need for further assessment. Copyright © 2014 Elsevier B.V. All rights reserved.

The anesthesia training program of the Saudi Commission for health specialties has introduced a developed competency-based anesthesia residency program starting from 2015 with the utilization of the workplace-based assessment (WBA) tools, namely mini-clinical exercises (mini-CEX), direct observation of procedural skills (DOPS), and case-based discussion (CBD). This work aimed to describe the process of development of anesthesia-specific list of mini-CEX, DOPS, and CBD tools within the Saudi Arabian Anesthesia Training Programs. To introduce the main concepts of formative WBA tools and to develop anesthesia-specific applications for each of the selected WBA tools, four 1-day workshops were held at the level of major training committees at eastern (Dammam), western (Jeddah), and central (Riyadh) regions in the Kingdom were conducted. Sixty-seven faculties participated in these workshops. After conduction of the four workshops, the anesthesia-specific applications setting of mini-CEX, DOPS, and CBD tools among the 5-year levels were fully described. The level of the appropriate consultation skills was divided according to the case complexity adopted from the American Society of Anesthesiologists physical classification for adult and obstetric and pediatric patient as well as the type of the targeted anesthetic procedure. WBA anesthesia-specific lists of mini-CEX, DOPS, and CBD forms were easily incorporated first into guidelines to help the first stage of implementation of formative assessment in the Saudi Arabian Anesthesia Residency Program, and this can be helpful to replicate such program within other various training programs in Saudi Arabia and abroad.

Full Text Available Objectives: To investigated the rate of occurrence of lumbosacral transitional vertebrae (LSTV, spinal variant, in kidney urinary bladder (KUB plain radiographs in a Saudi population. Methods: Between January 2012 to January 2015, KUB plain films obtained from patients at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, were reviewed, and the presence or absence of LSTV was documented and classified as incomplete or complete. Patients who had evidence of spinal surgery that would obscure the view were excluded. Results: A total of 2078 patients underwent KUB examinations during the study period; LSTV anomalies were detected in 158 of these. Sacralization was present in 153 (96.8% of this cohort, while lumbarization was present in 5 (3.2%. A total of 136 (86.1% of the sacralized segments were of the incomplete type, whereas 17 (10.7% were complete. Of the lumbarized vertebrae, 3 (1.8% were incomplete, and 2 (1.2% were complete. The most frequent type in men was type Ib (28.5% for sacralized segments, and type IIb for lumbarized segments (0.6%. In women, type Ia was the most common form of sacralized segments (11.3% and type IIb was the most common form of lumbarized segments (2.8%. Conclusion: The prevalence of LSTV in Saudi patients is 7.6%, with a higher incidence of sacralization than lumbarization. Further studies with larger sample sizes and longer follow-up time are needed to demonstrate the clinical significance thereof.

Ash Shuqayq (Saudi Red Sea coast) is approximately 28 km long and characterised by narrow rocky headlands with intermittent pocket beaches. Fifty-two sediment samples from six different environments (beach, dune, sabkha, tidal/lagoon, offshore and wadi) were analysed. Testing showed that beach and dune sands are mainly medium to fine grained, with some very coarse sand (MZ = − 0.59ø). 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. - Highlights: ► New and previously unpublished Red Sea sediment information. ► Sediment chemical and spatial variations established. ► Sabkha origins are similar for both UAE Arabian Sea and Saudi Arabian Red Sea coasts. ► Desalination plant shown as cause of increased marine sediment chlorite levels.

Hysterectomy is a common surgical procedure among women with a lifetime prevalence of 10%. The indications and complications of this procedure have not been previously reported from a teaching institution in Saudi Arabia. We examined the indications for hysterectomy and the surgical morbidity for women undergoing hysterectomy at a university hospital in Saudi Arabia. We reviewed the records of women who underwent hysterectomies for benign gynecological conditions between January 1990 and December 2002, at King Abdulaziz University Hospital (KAUH), Jeddah, Saudi Arabia, comparing patient characteristics, indications for hysterectomy and the rate of complications in women undergoing abdominal hysterectomy (AH) versus vaginal hysterectomy (VH). Of 251 women 199 (79%) underwent AH and 52 (21%) underwent VH. An estimated blood loss of >=500 mL occurred in 104 patients (52.3%) in the AH group and in 20 patients (38.5%) in the VH group (difference not statistically significant). The most common indications for hysterectomy were uterine fibroids (n=107, 41.6%) and dysfunctional uterine bleeding (n=68, 27.1%). The most common indication for VH was uterine prolapsed (n=45, 86.5%). The overall complication rates were 33.5%, 15.4% and 30.4% in women who underwent the AH group and in 51 patients in the VH group (20.3%). Postoperative infection occurred in 42/199 (21.6%) in the AH group and 5/52 (9.6%) in the VH group (difference not statistically significant). We describe a large series of hysterectomies, which provides information for surgeons on the expected of complications following hysterectomy for benign conditions. We describe a large series of hysterectomies, which provides information for surgeons on the expected rate of complications following hysterectomy for benign conditions. We found that the rate of complications was not significantly higher than other centers internationally. (author)

Fish contaminations have been extensively investigated in Saudi coasts, but studies pertaining to bacterial pathogens are meager. We conducted qualitative assessment and molecular identification of culture dependent bacteria in 13 fish species collected from three fishing sites and a local fish market in Jeddah, Saudi Arabia. The bacterial counts of gills, skin, gut and muscle were examined on agar plates of Macconkey’s (Mac), Eosin methylene blue (EMB) and Thiosulfate Citrate Bile Salts (TCBS) culture media. Bacterial counts exhibited interspecific, locational and behavioral differences. Mugil cephalus exhibited higher counts on TCBS (all body-parts), Mac (gills, muscle and gut) and EMB (gills and muscle). Samples of Area I were with higher counts, concurrent to seawater and sediment samples, revealing the influence of residing environment on fish contamination. Among feeding habits, detritivorous fish harbored higher bacterial counts, while carnivorous group accounted for lesser counts. Counts were higher in skin of fish obtained from market compared to field samples, revealing market as a major source of contamination. Bacterial counts of skin were positively correlated with other body-parts indicating influence of surface bacterial biota in overall quality of fish. Hence, hygienic practices and proper storage facilities in the Jeddah fish market is recommended to prevent adverse effect of food-borne illness in consumers. Rahnella aquatilis (Enterobacteriaceae) and Photobacterium damselae (Vibrionaceae) were among the dominant species identified from fish muscle samples using Sanger sequencing of 16S rRNA. This bacterial species are established human pathogens capable of causing foodborne illness with severe antibiotic resistance. Opportunistic pathogens such as Hafnia sp. (Enterobacteriaceae) and Pseudomonas stutzeri (Pseudomonadaceae) were also identified from fish muscle. These findings indicate bacterial contamination risk in commonly consumed fish of

Full Text Available Objectives: To assess knowledge regarding the management of odontogenic infections by dentists in Jeddah, Kingdom of Saudi Arabia. Methods: In this cross-sectional study, 150 practitioners responded to a 26-item paper-based questionnaire between August and December 2014. The questionnaire evaluated knowledge and current clinical practices in managing odontogenic infections, as well as the attitude towards antibiotic use and resistance in the community. Basic medical knowledge (BMK and critical knowledge (CK scores were calculated from the dentists’ response to these questions and were compared according to educational level (bachelor and postgraduate degree holders. Results: The mean BMK score was 1.98 ± 0.4 and CK score was 1.89 ± 0.3. Dentists with bachelor’s degrees had higher BMK scores than those with a postgraduate degree (p=0.005, but CK was not significantly different (p=0.400. Most dentists (77% would prescribe antibiotics after a routine dental extraction, and would undertake definitive surgical treatment (49.2% only after a localized space infection developed. Although 82.2% agreed that routine prescription of antibiotics increases bacterial resistance in the community, 71% believe that prescribing an antibiotic after routine oral surgical procedures prevents odontogenic infections. Conclusion: Dentists in Jeddah require further education through lectures and workshops to stay up to date on current concepts in odontogenic infection management.

Cyanobacterial mats are found at various locations along the coast of the Eastern Province of Saudi Arabia. Those mats were affected by severe oil pollution following 1991 oil spill. In this study, samples from Abu Ali Island were collected at three selected sampling sites across the intertidal zone (Lower, Middle, and Upper) in order to understand the effect of extreme environmental conditions of high salinity, temperature and desiccation on distribution of cyanobacteria along the oil polluted intertidal zone. Our investigation of composition of cyanobacteria and diatoms was carried out using light microscopy, and Denaturant Gradient Gel Electrophoresis (DGGE) technique. Light microscopy identification revealed dominant cyanobacteria to be affiliated with genera Phormidium, Microcoleus, and Schizothrix, and to a lesser extent with Oscillatoria, Halothece, and various diatom species. The analysis of DGGE of PCR-amplified 16S rRNA fragments showed that the diversity of cyanobacteria decreases as we proceed from the lower to the upper intertidal zone. Accordingly, the tidal regime, salinity, elevated ambient air temperature, and desiccation periods have a great influence on the distribution of cyanobacterial community in the oil polluted intertidal zone of Abu Ali Island.

Breast cancer (BC) accounts for 24 % of all women cancer cases diagnosed in Saudi Arabia each year. Awareness is extremely important in combating this disease. This study was undertaken to assess male high school students' response to BC. This cross-sectional survey was performed on male high school students across schools in Jeddah. A questionnaire gathered data on respondent demographics, beliefs about BC, BC risk factors, early screening methods, and role of men in BC. Statistical analysis was done using SPSS 20. A total of 824 students participated, with an average age of 17.0 years. There was more than 50 % agreement that early detection of BC enhances the chances of recovery, that BC is treatable, and that clinical breast examination and breastfeeding provide protection from BC. Around half the survey population thought that BC was fatal and contagious. Fewer than 50 % thought that BC was inherited and related to smoking, consumption of contraceptive pills, repeated exposure to radiation, obesity, and wearing a bra and that breast tumors were all malignant and spread to different parts of the body. Others knew that mammograms should be performed periodically. A high percentage persuaded their relatives to have mammograms and provided them with psychological support. Knowledge of BC among male high school students in Saudi Arabia is still limited, and, therefore, programs and activities need to be established to increase awareness among high school students.

Family-centred care is widely accepted as the underlying philosophy of paediatric nursing. Studies of family-centred care have mainly been conducted in western countries and little is known of its practice in other contexts. No studies have been undertaken in the Middle East. To explore family-centred care in the Saudi context from the perspectives of paediatric nurses. A mixed methodology was utilised with an explanatory sequential design. In the quantitative phase a convenience sample of 234 nurses from six hospitals in Jeddah, Saudi Arabia completed the Family Centred Care Questionnaire. The qualitative phase took place in one hospital and involved 140h of non-participant observation of paediatric nurses' practice. A convenience sample of 14 nurses was involved. Additionally, 10 face-to-face semi-structured interviews were conducted with key staff members. A purposeful sample of 10 nurses was involved. The findings from both phases were integrated in the final analysis. The survey results indicated that participants identified most elements of family-centred care as necessary for its practice. They were less likely to incorporate them into their practice (pworked with the elements as a set of core tasks. In the current study, there were similarities between what has been found in the Saudi context and findings from other studies using the same tool in western contexts. There is general agreement regarding the differences between theory and practice. Nurses do believe and acknowledge the importance of family-centred care; however, they struggle with practising this model in their everyday work. In the current study, many factors contributed to this issue, including language barriers, communication issues, cultural issues and hospital policies. Western concepts of family-centred care appear to be accepted by paediatric nurses in Saudi Arabia. However, full adoption of family-centred care in keeping with western values is likely not to be appropriate or successful

Objectives: To determine the prevalence of hypothyroidism in a cohort of Saudi women with heart failure; to define the demographic variables associated with heart failure; and the impact of hypothyroidism on systolic function in relation to non-hypothyroidism group. Methods: The cross-sectional cohort study was conducted at King Abdulaziz University Hospital, Jeddah, Saudi Arabia, and comprised all women diagnosed with heart failure who were seen in the Cardiology outpatients clinic between February 2010 and March 2013. All of them were subjected to complete medical history and clinical examination, including complete cardiac clinical examination, electrocardiogram, echocardiography, blood pressure reading as well as thyroid examination. Laboratory tests were performed for thyroid stimulating hormone, total cholesterol, triglycerides, low-density lipoprotein and high-density lipoprotein. Results: Of the 111 patients, 37 (33.3 percent) had hypothyroidism (p<0.001), and 16(14.4 percent) of them showed subclinical hypothyroidism. The mean value for thyroid stimulating hormone was 4.79+/-4.98U/L. There was a significant negative correlation between thyroid stimulating hormone and ejection fraction. Conclusion: There was close relation between hypothyroidism and heart failure. Further large-scale studies are recommended for early detection of hypothyroidism. (author)

The rifted margin of Saudi Arabia

Science.gov (United States)

McClain, J. S.; Orcutt, J. A.

The structure of rifted continental margins has always been of great scientific interest, and now, with dwindling economic oil deposits, these complex geological features assume practical importance as well. The ocean-continent transition is, by definition, laterally heterogeneous and likely to be extremely complicated. The southernmost shotpoints (4, 5, and 6) in the U.S. Geological Survey seismic refraction profile in the Kingdom of Saudi Arabia lie within a transition region and thus provide a testing ground for methods that treat wave propagation in laterally heterogeneous media. This portion of the profile runs from the Farasan Islands in the Red Sea across the coast line and the Hijaz-Asir escarpment into the Hijaz-Asir tectonic province. Because the southernmost shotpoint is within the margin of the Saudi sub-continent, the full transition region is not sampled. Furthermore, such an experiment is precluded by the narrowness of the purely oceanic portion of the Red Sea.

The objective of this study is to investigate the correlation between the psychomotor skills and the academic performance of dental students. Didactic and preclinical scores were collected for students who graduated from the Faculty of Dentistry, King Abdulaziz University, Jeddah, Saudi Arabia, in 2011. Three courses (Dental Anatomy, Removable Prosthodontic Denture, and Orthodontics) were selected. Correlations comparing didactic and practical scores were done for the total samples, then for the males and females separately. There was no significant correlation between the practical and didactic scores for the three courses for the total sample. There was a significant correlation between all three subjects in the didactic scores. For females, the results showed that there was only a significant correlation between the practical and didactic scores for Dental Anatomy. For males, no correlation was observed between the practical and didactic scores for all subjects. In the present sample, didactic performance did not correlate well with the students' psychomotor performance.

Nowadays, Cardiovascular Diseases (CVDs) represents an escalating worldwide public health problem. Providing consistent data on the magnitude and risk factors of CVDs among young population will help in controlling the risks and avoiding their consequences. The objective was to estimate the prevalence of risk factors of Coronary Heart Disease (CHD) among medical students during their clinical clerkship (4th - 6th years). A cross-sectional study was done during the educational year 2012-2013 at King Abdulaziz University (KAU), Jeddah. Ethical standards were followed and a multistage stratified random sample method was used for selection of 214 medical students. Data was collected through an interviewing questionnaire, measurements and laboratory investigations. Both descriptive and analytical statistics were done by SPSS version 21. CHD risk percent in thirty years was calculated using Framingham algorithm for each student, then the risk among all students was determined. The commonest risk factors of CHDs were daily intake of high fat diet (73.4%), physical inactivity (57.9%), overweight/or obesity (31.2%) and daily consumption of fast food (13.1%). Hyper-cholesterolemia (17.2%) and hypertension (9.3%) were also prevalent risk factors. Smoking prevalence was low (2.8%). Males had significantly higher mean scores for most of CHD risk factors compared to females (p Students't test = 4.74, p students was 10.7%, 2.3% and 0.5% for mild, moderate and severe risk, respectively. An alarmingly high prevalence of CHD risk factors was prevailed among medical students, especially among males. However, a low prevalence of smoking may indicate the success of "Smoke-free Campus" program. Screening risk factors of CHD among medical students and implementation of intervention programs are recommended. Programs to raise awareness about CHD risk factors, encourage young adult students to adopt a healthy dietary behavior and promote physical exercise should be initiated.

To evaluate the relationship between body mass index (BMI) and the duration spent on electronic devices, and to assess the factors that can cause obesity among children. A cross-sectional study including 541 participants. Data was collected from March to June 2015 via ambulatory pediatric clinics in Jeddah, Kingdom of Saudi Arabia. The BMI standard deviation was calculated based on Center of Disease Control and Prevention (CDC) standards. The mean age of the participants was 10.1 years. Children who spent ≥2 hours daily on electronic devices showed an increased BMI, and made up 68.4% of the sample. An increased BMI was more common among children who spent ≥2 hours daily on electronic devices. The relationship between BMI, reduced physical activity, and eating during television viewing was determined.

Objective was to estimate the incidence of major and minor congenital malformations among live born infants at King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Estimation of risk factors was also evaluated. Between March 2004 and May 2005, a total of 5356 babies born at King Abdulaziz University Hospital, were enrolled in this study for malformations. Details of cases were recorded after parent's interviews, clinical, radiological and laboratory evaluations. One hundred and forty-seven (27.06/1000 livebirth) and 13 (2.39/1000 birth) stillbirth have congenital anomalies. In all livebirth, incidences of major anomalies were 93.9% and minor were 6.1%. Mothers of 95.9% with congenital malformation were healthy, 3.4% were diabetic and 0.7% had cardiac malformation. In 38.8% of cases parents were consanguineous. Among the liveborn births, the most common system involved was cardiovascular (7.1/1000), followed by musculoskeletal/limb (4.1/1000), external genitilia (2.8/1000), urinary (2.6/1000),multiple chromosomal (2.2/1000), orofacial (1.9/1000), central nervous system (1.9/1000), skin (1.7/1000), multiple single gene (1.3/1000), multiple sequence (0.75/1000), eyes (0.56/1000), unclassified (0.19/1000), musculoskeletal/abdominal (0.19/1000), endocrine (0.19/1000). High incidence of major malformation was found in Jeddah. Importance of Genetic Counseling is revealed in our study since more than three quarters of mothers were under 36 years and may well plan future pregnancies. (author)

The objective of this study was to estimate the survival of Gambusia holbrooki (Cyprinodontiformes: Poeciliidae) fishin domestic containers in Jeddah, as well as its effectiveness in the control of immature A.aegypti. The use of G. holbrooki compared to Bacillus thuringiensis israelensis (B.t.i.)was donein domestic containers. In a first home visit, G. holbrooki or B.t.i were applied to water containers. Two follow-up visits were conducted after 3-4 & 5-6 months to assess the presence of viable fish in the containers and infestation by larvae. G. holbrooki fish were still present in 97.6% of containers 45-60 days after application. The infestation rate was significantly higher (P < 0.001) in the B.t.i group (IR ratio=21.60, 95% CI: 6.46-72.28). In deposits where the fish remained, efficacy was 85% better than B.t.i. The permanence of fish was higher in concrete tanks (48.5%) located outside the house (47.5%) and at ground level (53.3%).

Methods: This study is a biometric analysis of dental casts of 149 young adults recruited from different orthodontic centers in Jeddah, Saudi Arabia. The dental arch dimensions were measured. The measured parameters were arch length, arch width, Bolton’s ratio, and arch form. The data were analyzed using IBM SPSS software version 22.0 (IBM Corporation, New York, USA; this cross-sectional study was conducted between April 2015 and May 2016. Results: Dental arch measurements, including inter-canine and inter-molar distance, were found to be significantly greater in males than females (p less than 0.05. The most prevalent dental arch forms were narrow tapered (50.3% and narrow ovoid (34.2%, respectively. The prevalence of tooth size discrepancy in all cases was 43.6% for anterior ratio and 24.8% for overall ratio. The mean Bolton’s anterior ratio in all malocclusion classes was 79.81%, whereas the mean Bolton’s overall ratio was 92.21%. There was no significant difference between males and females regarding Bolton’s ratio. Conclusion: The most prevalent arch form was narrow tapered, followed by narrow ovoid. Males generally had larger dental arch measurements than females, and the prevalence of tooth size discrepancy was more in Bolton’s anterior teeth ratio than in overall ratio.

Psychopathic personality traits have been shown to increase the odds of a wide range of antisocial outcomes. Very little research, however, has examined the association between psychopathy and the risk of personal victimization. The current study address this gap in the literature by examining the association between scores on the Levenson Self-Report Psychopathy scale and a self-reported measure of victimization by using cross-sectional data drawn from a sample of youth residing in Jeddah, Saudi Arabia (N = 311). The results revealed a positive and statistically significant association between LSPR scores and the odds of being victimized. Additional analyses revealed that two mediators-arrest history and exposure to delinquent peers-were related to personal victimization, but neither of these measures mediated the effects of LSPR scores on victimization. Whether these findings would generalize to other nations remains an issue awaiting future research.

This work outlines a new approach for the integration of 3D Building Information Modelling and the 3D Geographic Information System (GIS) to provide semantically rich models, and to get the benefits from both systems to help document and analyse cultural heritage sites. Our proposed framework is based on the Jeddah Historical Building Information Modelling process (JHBIM). This JHBIM consists of a Hijazi Architectural Objects Library (HAOL) that supports higher level of details (LoD) while decreasing the time of modelling. The Hijazi Architectural Objects Library has been modelled based on the Islamic historical manuscripts and Hijazi architectural pattern books. Moreover, the HAOL is implemented using BIM software called Autodesk Revit. However, it is known that this BIM environment still has some limitations with the non-standard architectural objects. Hence, we propose to integrate the developed 3D JHBIM with 3D GIS for more advanced analysis. To do so, the JHBIM database is exported and semantically enriched with non-architectural information that is necessary for restoration and preservation of historical monuments. After that, this database is integrated with the 3D Model in the 3D GIS solution. At the end of this paper, we'll illustrate our proposed framework by applying it to a Historical Building called Nasif Historical House in Jeddah. First of all, this building is scanned by the use of a Terrestrial Laser Scanner (TLS) and Close Range Photogrammetry. Then, the 3D JHBIM based on the HOAL is designed on Revit Platform. Finally, this model is integrated to a 3D GIS solution through Autodesk InfraWorks. The shown analysis presented in this research highlights the importance of such integration especially for operational decisions and sharing the historical knowledge about Jeddah Historical City. Furthermore, one of the historical buildings in Old Jeddah, Nasif Historical House, was chosen as a test case for the project.

Radiographic repeat rate data in diagnostic radiology in King Fahad Hospital (KFH), King Abdulaziz Hospital (KAH), and Maternity and Children Hospital (MCH) in Jeddah, Saudi Arabia, have been studied. The study provided valuable information to suggest preventive measures to reduce repeats. The variables included in the study are exposure techniques, examination types, total number of films used, number of films repeated, the film sizes, gender, the age groups of the patients, and reason for repetition. The total number of examinations in all three hospitals is 6001 using 8887 films on 5412 patients. The average repeat rate was 7.93%, where the individual hospital repeat rates were 9.57% in the MCH, 7.84% in KAH and 7.44% in KFH. The repeat rate for children and infants was found to be undesirable. The quality assurance (QA) programme can effectively reduce the unnecessary exposure and can identify the cause of the exposure. The overexposure, underexposure and position fault were the foremost contributors for repeats and constitute 32.91%, 28.94% and 22.98% of the total respectively. The QA study identified that human error and equipment malfunction are the major contributors to these causes of repeats. The highest repetition rate was for pelvis, 13.64%, followed by skull, 11.59%, and abdomen, 10.41%. It is estimated that the total area of wasted film in all three hospitals is 74.3 m 2 . As per the average repeat rate, the cost of repeat films in the entire kingdom per year has been projected to be about US$1.82 million (SR 6.83 million) in the government hospitals only. Based on the findings of this study a set of recommendations have been prescribed for the radiology department to reduce the repeat rate and to improve the safety culture. (author)

Adolescence is an important period in an individual's life. Overweight and obesity are fraught with several health problems even late in life. The objective of this study was estimate the overweight, obesity, body fat and muscle content of Saudi adolescents as compared to a recognized reference population. Data were collected from a sample of Saudi adolescents in Jeddah from 42 boys' and 42 girls' school during the month of April 2000. Data collection was done by personal interviews to collect sociodemograhic factors and by direct measurement of weight, height, triceps skin fold thickness (TSF) and mid-arm circumference (MAC). The 50th, 85th and 95th percentiles(P50, P85 and P95) for body mass index (BMI) and triceps skin fold thickness (TSF) were taken, then the 50th, 90th, and 95th percentiles (P50, P90 and P95) for the mid-arm muscle circumference (MAMC) were calculated. These measurements were compared with corresponding values of the National Health and Nutrition Examination Survey I (NHANES I). The P85 and P95 for the BMI and TSF were higher for Saudi adolescents than the NHANES I and the difference was wider for P95. Conversely, there was a lower MAMC at P90 and P95thane the NHANES I reference population curves. The lower MAMC curves were less marked in girls than in boys. On the other hand Saudi boys and girls showed on average similar body mass index indicated by MBI at P50, which was misleading, since those adolescents showing similar body mass index had more fatness than of average reference population indicated by TSF and P50, and less muscularity on average than reference population indicated MAMC at P-50. Overweight and obesity with increased body fat content and decreased body muscle content appear to be widespread among Saudi adolescents even among those adolescents showing average body index. Public health interventions are required to improve quality of food, encourage physical, activity and exercise, as well as correct the perception of

The aim of this study is to investigate the variability of aerosol over The Kingdom of Saudi Arabia. For this analysis, Moderate Resolution Imaging Spectroradiometer (MODIS) Deep Blue (DB) Aerosol Optical Depth (AOD) product from Terra and Aqua satellites for the years 2000–2013 is used. The product is validated using AERONET data from ground stations, which are situated at Solar Village Riyadh and King Abdullah University of Science and Technology (KAUST) Jeddah. The results show that both Terra and Aqua satellites exhibit a tendency to show the spatial variation of AOD with Aqua being better than Terra to represent the ground based AOD measurements over the study region. The results also show that the eastern, central, and southern regions of the country have a high concentration of AOD during the study period. The validation results show the highest correlation coefficient between Aqua and KAUST data with a value of 0.79, whilst the Aqua and Solar Village based AOD indicates the lowest Root Mean Square Error (RMSE) and Mean Absolute Error (MAE) values which are, 0.17 and 0.12 respectively. Furthermore, the Relative Mean Bias (RMB) based analysis show that the DB algorithm overestimates the AOD when using Terra and Solar Village data, while it underestimates the AOD when using Aqua with Solar Village and KAUST data. The RMB value for Aqua and Solar Village data indicates that the DB algorithm is close to normal in the study region. - Highlights: • The significance of aerosol in the Kingdom of Saudi Arabia is addressed. • MODIS (Terra and Aqua), AERONET and ground based sand event data is used. • MODIS DB product is used to prepare annual aerosol maps and monthly AOD variability. • A comparison is made between Terra and Aqua AOD product over bright surface. • MODIS DB AOD product is validated using AERONET data at Solar Village and KAUST. - This research highlighted the aerosol variability over The Kingdom of Saudi Arabia by using Satellite, AERONET

Full Text Available During the period from 1964 to 1999 Saudi Arabian species of Salicornia were wrongly treated under the European species, S. europaea L. Recent explorations proved that there are two separate allopatric species of Salicornia in Saudi Arabia, one inhabiting the inland salt-marshes of the Najd (highlands and the other inhabiting the Arabian Gulf Coast (lowlands. Morphological, ecological and exploratory studies confirm that they are two distinct species. The two species differ in features of bark, axillary spikes, basal vegetative segment(s of spike, fertile segments, colour of senescent plants, and flowering, fruiting and germination phenology. As both the species have been described earlier from Iran, they are now new records for Saudi Arabia. The species are, S. persica ssp. iranica (Akhani Kadereit & Piirainen and S. sinus-persica Akhani. S. sinus-persica, of which the status was thought doubtful has been confirmed. Both the species have been described and illustrated. Each species comprises a number of polymorphs. As leaves and flowers are rudimentary, confusing species circumscriptions, a proliferation of binomials has resulted in the taxonomy of Salicornia. To mitigate such confusion, the full range of variability of the Saudi Arabian species has been documented.

Objectives: To describe the characteristics and prevalence of non-syndromic orofacial clefting (NSOFC) and assess the effects of parental consanguinity on NSOFC phenotypes in the 3 main cities of Saudi Arabia. Methods: All infants (114,035) born at 3 referral centers in Riyadh, and 6 hospitals in Jeddah and Madinah between January 2010 and December 2011 were screened. The NSOFC cases (n=133) were identified and data was collected through clinical examination and records, and information on consanguinity through parent interviews. The diagnosis was confirmed by reviewing medical records and contacting the infants’ pediatricians. Control infants (n=233) matched for gender and born in the same hospitals during the same period, were selected. Results: The prevalence of NSOFC was 1.07/1000 births in Riyadh, and 1.17/1000 births overall; cleft lip (CL) was 0.47/1000 births, cleft lip and palate (CLP) was 0.42/1000 births, and cleft palate (CP) was 0.28/1000 births. Cleft palate was significantly associated with consanguinity (p=0.047, odds ratio: 2.5, 95% confidence interval: 1 to 6.46), particularly for first cousin marriages. Conclusion: The birth prevalence of NSOFC in Riyadh alone, and in the 3 main cities of Saudi Arabia were marginally lower than the mean global prevalence. While birth prevalence for CLP was comparable to global figures, the CL:CLP ratio was high, and only CP was significantly associated with consanguinity. PMID:26318465

During November 2008 to January 2009, 11 babies in the neonatal intensive care (NICU) and three babies in the nursery were infected with Serratia marcescens at King Abdulaziz University Hospital in Saudi Arabia. Overall, fifteen infections were identified among 11 newborns in the NICU: septicaemia (five cases), purulent conjunctivitis (three), urinary tract infection (two), meningitis (two) and cellulitis (one). Three newborns in the nursery had three infections: purulent conjunctivitis (two cases) and omphalitis (one). Thirteen of 14 babies recovered fully but one died from S. marcescens meningitis and septicaemia. All infections were traced to intrinsically contaminated baby shampoo introduced to the units five days before the first reported case. The outbreak terminated following withdrawal of the shampoo product. Copyright © 2011 The Healthcare Infection Society. Published by Elsevier Ltd. All rights reserved.

The Chernobyl reactor accident released large amounts of radioactivity that was carried by winds across international boundaries. Soils and surface waters as well as vegetation and grazing animals in neighbouring countries to the Soviet Union were subject to radioactive contamination in various degrees. Saudi Arabia imports much of its foodstuffs from European countries and about 75% of the imported foodstuffs come through western ports of the country. Hence the Government of Saudi Arabia took appropriate measures to ensure safety of imported foodstuffs. King Abdulaziz University (KAU) was directed by the government at about mid-June 1986, to carry out radioactivity inspections of food items reaching Jeddah, Yanbu and Jizan seaports as well as food arrivals at King Abdulaziz International Airport at Jeddah. Parallel responsibilities were assigned to other universities and King Abdulaziz City for Science and Technology, for radioactivity inspections of imported foodstuffs reaching ports or inlets in their respective areas. In applying the measures and controls enacted by the government against importation of radioactively contaminated foodstuffs, much management experience was acquired and some of it is rather unique to Saudi Arabia

Full Text Available Objectives. The aim of the study was to evaluate the influence of sweet taste perception on dietary habits in Saudi schoolchildren. In addition, the relationship between dietary habits and both caries and BMI was studied. Methods. A cross-sectional observational study comprising 225 schoolchildren aged 13–15 years from Jeddah, Saudi Arabia, was conducted. The consumption frequency of certain food items was analysed from a beverage and snack questionnaire and a three-day estimated dietary record was obtained. The sweet taste perception level was determined as sweet taste threshold (TT and sweet taste preference (TP. Children were grouped into low, medium, and high, according to their sweet taste perception level. ICDAS and DMFS indices were used for caries registration and anthropometric measurements using BMI were collected. Results. Sweet taste perception was found to be negatively correlated to the number of main meals and positively correlated to both snack and sweet intake occasions. Statistically significant differences were found between the TT and TP groups with regard to the number of main meals and sweet intake (p≤0.01. No significant correlation between the dietary variables and caries or BMI was found. Conclusions. The dietary habits and sweet intake were found to be influenced by the sweet taste perception level, while the relation between the dietary habits and the caries and BMI was found insignificant.

This paper investigates the effectiveness of the Building Energy Management System (BMS) installed in the typical buildings in the main campus of King Abdulaziz University, Jeddah, in Saudi Arabia. As the domestic electricity and hence the oil consumption in Saudi Arabia is increasing at a very alarming rate compared to the other countries in the world, it is of paramount importance to resort to urgent measures in various industrial, commercial and residential sectors in the country to implement energy conservation measures. The major electrical load in the buildings in the University corresponds to air-handling units and lighting. If the Hajj period, during which millions of pilgrims visit Holy Makah, coincides with the summer, the electricity demand in the country further increases. Considering these issues, the university has taken initiatives to minimize energy consumption in the campuses through the various energy conservation measures. Towards this end, BMS is installed in a few of the typical classrooms and office buildings utilizing the existing campus Ethernet TCP/IP. The data analysis is performed over the period from April to September as it is the peak load period due to summer season. The effectiveness of the BMS in the minimization of the energy consumption in these buildings is established by comparing the results of data analysis with BMS against those before the installation of BMS over the peak period. The investigations reveal that appreciable saving in energy consumption can be achieved with the installation of BMS, the magnitude being dependent upon factors such as building characteristics, type of building, its utilization and period of use.

Health ATMs are terminals which are connected to a centrally located database storing patients' electronic healthcare records (EHR). These machines are capable of collecting information in a far superior fashion than humans and are also able to rectify obsolete data in a manner that humans are generally not inclined to. The main goal of this study is to assess the importance of adopting health ATMs in the Kingdom of Saudi Arabia (KSA), which can improve the confidence of patients, reward health self-management, and achieve positive health outcomes through their easy-to-use applications that are secure and accessible through various devices. Strength, Weakness, Opportunity, and Threat (SWOT) analysis was used to assess the efficiency of adopting health ATMs in KSA and reveal the said characteristics. Three focus groups assembled in the cities of Riyadh, Jeddah and Dammam during the period 2013-2014. The groups consisted of individuals experienced in the function of health ATMs. It was found that the sector possessed a number of strengths that would help it in reaching the goals outlined therein, thereby achieving successful outcomes. Health ATMs could be a promising new advancement in the field of health if the project were to be planned and implemented correctly. Their benefits would consequently reach organizational and national levels. It is, therefore, crucial to educate the project managers about the benefits of learning from others as well as educating them about the needs and the requirements of the concerned organization.

2017-11-01

In this study solar driven absorption chiller is used to reduce the peak cooling load in office buildings in Saudi Arabia for different selected cities. The study is conducted for six cities of Abha, Dhahran, Hail, Jeddah, Nejran and Riyadh under three operating durations of 4, 6, and 8 hours using flat plate or evacuated tube collectors. The energy analysis concluded that flat plate collectors are better than evacuated tube collectors. However, the results from economic analysis suggest that while proposing a gas fired absorption chiller will reduce running costs, further reduction by using solar collectors is not feasible because of its high initial cost. At the best case scenario the Net Present Value of a 10 Ton Absorption chiller operated by natural gas boiler and two large flat plate collectors (12m2 each) running for 8 hours/day, 5days/week has a value of 117,000 and Internal Rate of Return (IRR) of 12%. Solar driven absorption chiller could be more feasible if the gas prices increases or the solar collector prices decreases significantly. Finally, government economic incentives and taxes are recommended to provide a boost for the feasibility of such projects.

Full Text Available Aim To compare the effect of different treatment regimens (oral hypoglycemic agents [OHGs], insulin therapy, and combination of both on glycemic control and other cardiometabolic risk factors in type 2 diabetes mellitus (T2DM patients in Saudi. Subjects and Methods Patients with T2DM, but no serious diabetic complications, were randomly recruited from the diabetes clinics at two large hospitals in Jeddah, Saudi Arabia, during June 2013 to July 2014. Only those without change in treatment modality for the last 18 months were included. Blood pressure and anthropometric measurements were measured. Treatment plan was recorded from the patients' files. Fasting blood sample was obtained to measure glucose, HbA1c, and lipid profile. Results A total of 197 patients were recruited; 41.1% were men and 58.9% were women. The mean (±SD age was 58.5 ± 10.5 years. Most patients (60.7% were on OHGs, 11.5% on insulin therapy, and 27.7% were using a combination of insulin and OHGs. The mean HbA1c was lower in patients using OHGs only, compared with means in those using insulin, or combined therapy in patients with disease duration of #10 years ( P = 0.001 and also in those with a longer duration of the disease ( P < 0.001. A lower mean diastolic and systolic blood pressure was found among patients on insulin alone ( P < 0.01. No significant differences were found in lipid profiles among the groups. Conclusion Insulin therapy, without adequate diabetes education, fails to control hyperglycemia adequately in Saudi T2DM patients. There is a challenge to find out reasons for poor control and the ways as to how to improve glycemic control in T2DM.

To explore the role of radiological examination and certain biochemichal values in diagnosing and assessing severity of nutritional rickets. There were cases of nutritional rickets (age range between 3-36 months) seen at King Abdul-Aziz University Hospital, Jeddah,Kingdom of Saudi Arabia, during the period 1997-1999 were studied. Determinatin of calcium (Ca), phosphate(PO4),alkaline phosphate(ALP),hand and wrist x-rays,were performed for all cases. 60 cases of nutritional rickets were dignosed within 2 years,38.3% of the patients presented with swollen wristand 28.3% with bowleg.The bone profile at the time of diagnosis: Ca=2.33+-0.23,PO4=1.47+-0.40 and ALP=925+-418. Approximately 81.7% of the patients had a normal of Ca level, 18.3% had low serum PO4 level, 98.3%high value of ALP. X-ray studies indicated that,58.3% of patients have active rickets, 35% had minimal changes, and 6.7% showed healed rickets. Among those having active rickets 20% had low PO4 level ,83% had normal Ca vlaue , and 100% had high ALP.The mean value +- Sd of biochemical values in this group : Ca=2.34+-0.24, PO4= 1.45+-0.42,ALP=1067+-452. The later was significantly higher compared to other groups (P=0.004). Radiological examination and ALP remains essential to confirm clinical diagnosis of rickets and assessment of severity.

To assess the relative validity and repeatability of a sixty-four-item FFQ for estimating dietary intake of Zn and its absorption modifiers in Saudi adults. In addition, we used the FFQ to investigate the effect of age and gender on these intakes. To assess validity, all participants completed the FFQ (FFQ1) and a 3 d food record. After 1 month, the FFQ was administered for a second time (FFQ2) to assess repeatability. Jeddah, Saudi Arabia. One hundred males and females aged 20-30 years and 60-70 years participated. Mean intakes of Zn and protein from FFQ1 were significantly higher than those from the food record while there were no detectable differences between tools for measurement of phytic acid intake. Estimated intakes of Zn, protein and phytate by both approaches were strongly correlated (Prange of intakes while for Zn and phytic acid, the difference increased with increasing mean intake. Zn and protein intakes from FFQ1 and FFQ2 were highly correlated (r>0·68, Padults consumed less Zn and protein compared with young adults. Intakes of all dietary components were lower in females than in males. The FFQ developed and tested in the current study demonstrated reasonable relative validity and high repeatability and was capable of detecting differences in intakes between age and gender groups.

2005-01-01

This paper presents the selection criteria generally and seismic criteria specifically to select a suitable site in Saudi Arabia for a nuclear desalination plant. These criteria include geological, meteorological, cooling water supply discharge, transport infrastructure, population, electric grid, water network capacity, environmental impact and airport movement. The seismicity of the Arabian peninsula for the locations of seismic activity along the Red Sea and the Arabian Gulf coastlines from 1973 to 2000 was studied carefully. This study included towns and locations along the east and west coastlines and their distances from the seismic event site. The results showed that Rabigh City along the west coast of Saudi Arabia is a good site to build a nuclear desalination plant. This is because of the following reasons: good seismic stability; good weather statistics; no flooding; mild wave conditions; good supply and discharge; good transportation infrastructure; low population area; very close to the huge electric grid.

The Saudi Healthcare System is universal, financed entirely from government revenue principally derived from oil, and is 'free at the point of delivery' (non-contributory). However, this system is unlikely to be sustainable in the medium to long term. This study investigates the feasibility and acceptability of healthcare financing reform by examining households' willingness to pay (WTP) for a contributory national health insurance scheme. Using the contingent valuation method, a pre-tested interviewer-administered questionnaire was used to collect data from 1187 heads of household in Jeddah province over a 5-month period. Multi-stage sampling was employed to select the study sample. Using a double-bounded dichotomous choice with the follow-up elicitation method, respondents were asked to state their WTP for a hypothetical contributory national health insurance scheme. Tobit regression analysis was used to examine the factors associated with WTP and assess the construct validity of elicited WTP. Over two-thirds (69.6%) indicated that they were willing to participate in and pay for a contributory national health insurance scheme. The mean WTP was 50 Saudi Riyal (US$13.33) per household member per month. Tobit regression analysis showed that household size, satisfaction with the quality of public healthcare services, perceptions about financing healthcare, education and income were the main determinants of WTP. This study demonstrates a theoretically valid WTP for a contributory national health insurance scheme by Saudi people. The research shows that willingness to participate in and pay for a contributory national health insurance scheme depends on participant characteristics. Identifying and understanding the main influencing factors associated with WTP are important to help facilitate establishing and implementing the national health insurance scheme. The results could assist policy-makers to develop and set insurance premiums, thus providing an additional source

Saudi Arabia : emerging with influence

International Nuclear Information System (INIS)

Al-Qudsi, S.

2006-01-01

Energy and the Saudi economy were discussed with reference to reserves, oil prices, gross domestic product co-movements, and gas resources and development. In particular, this presentation reviewed the emergence and prospects of the petrochemical industry of Saudi Arabia using statistical, institutional and economic analyses relying on a wide range of data sources. Saudi Arabia has the world's largest oil reserves, at 263 billion barrels. In the 1990s, more than 54 Tcf of non-associated gas reserves were added to Saudi Arabia's resource base, more than doubling its proven non-associated gas reserves to approximately 97 Tcf. With 138 Tcf of associated gas reserves, Saudi Arabia holds the fourth largest gas reserves in the world at nearly 235 Tcf. First, this presentation identified and evaluated the endowments as well as the institutional and strategic forces that are driving the growth of the petrochemical industry in Saudi Arabia. Some of the economic, technical and geopolitical factors that influenced the increase in oil prices between 2003 and 2005 were also identified. The dual relationship between the Saudi petrochemical industry and long term economic performance of the Saudi economy were illustrated within a broad domestic economic diversification policy objective. The future growth prospects and challenges facing the Saudi petrochemical industry were also evaluated with respect to the evolving economic reform policies and Saudi international commitments. Potential implications for the petrochemical industry in North America were also identified, in terms of technology transfer and having Saudi Arabia secure the markets in order to meet its commitment to the World Trade Organization. tabs., figs

Twenty three morphologically distinct microbial colonies were isolated from soil and sea water samples, which were collected from Jeddah region, Saudi Arabia for screening of the most potent biosurfactant strains. The isolated bacteria were selected by using different methods as drop collapse test, oil displacement test, blue agar test, blood hemolysis test, emulsification activity and surface tension. The results showed that the ability of Virgibacillus salarius to grow and reduce surface tension under a wide range of pH, salinities and temperatures gives bacteria isolate an advantage in many applications such as pharmaceutical, cosmetics, food industries and bioremediation in marine environment. The biosurfactant production by V. salarius decreased surface tension and emulsifying activity (30 mN/m and 80%, respectively). In addition to reducing the production cost of biosurfactants by tested several plant-derived oils such as jatropha oil, castor oils, jojoba oil, canola oil and cottonseed oil. In this respect the feasibility to reusing old frying oil of sunflower for production rhamnolipids and sophorolipids, their use that lead to solve many ecological and industrial problems.

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

The largest crude oil commodity market in the world--the US Gulf Coast--has experienced an important change in recent years. The decline in domestic production and the increase in imports appear destined to accelerate in the coming decades. Latin American countries will continue to be a major source of US imports, and that the shortfall will have to be made up using Middle Eastern crudes, primarily those from Saudi Arabia and Kuwait. The paper discusses economics, US production, imports, and future trends

Acrylamide (AA) is a carcinogenic and genotoxic food contaminant produced at high temperatures in foods that are rich in carbohydrates. Foods sold in schools in Jeddah, Saudi Arabia, are among such carbohydrate-rich foods produced at high cooking temperatures. It is crucial to determine the importance of AA exposure with respect to cafeteria foods and assess the associated risks. The highest mean AA level was measured in chocolate pies (439 µg kg -1 ), followed by custard pies (435 µg kg -1 ) and cheese pies (432 µg kg -1 ). The average and 95th percentile values of AA exposure were 0.51 and 1.17 [µg kg -1 body weight (BW) school day -1 ]. The average exposure significantly decreased with an increase in age, from 0.65 (µg kg -1 BW school day -1 ) in primary school students to 0.37 in secondary school students. Cheese and chocolate pies are the main contributors in AA intake. The contributions of cheese and chocolate pies to the average exposure among primary, middle and secondary school students were 23.1%, 24.7% and 29.4% and 16.9%, 12.1% and 11.9%, respectively. Other products with significant contributions included cheese sandwiches (10.8%, 8.9% and 12.7%), plain cookies (7.7%, 5.6% and 6.7%) and custard pies (7.7%, 4.8% and 8.9%). Other cafeteria products contributed to AA exposure at much lower percentages. The calculated margins of exposure (MOEs) for the average [356 and 614 for both benchmark dose lower confidence limit (BMDL) 0.18 and 0.31 mg kg -1 BW day -1 ] and 95th percentile AA exposure values (154 and 265 for both BMDL 0.18 and 0.31 mg kg -1 BW day -1 ) suggest that there is a health concern with respect to school-aged students. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Selecting a nuclear power plant site for power production and water desalination is a very complex problem, especially in countries with moderate technology. Many interrelated factors affect the process, and professional judgments by various experts are involved. Four sites, all located on the West Coast of Saudi Arabia along the Red Sea, were chosen as potential sites for building such a plant. (All sites were in either the northern or southern section of the coast; the central part was excluded for pilgrims' safety.) The East Coast was completely eliminated in the initial screening process due to its strategic location, the existence of oil fields and refineries, and its proximity to other Arabian (Persian) Gulf countries (to minimize radioactive releases to these countries in case of an accident). A computer code based on Saaty's eigenvalue technique and developed in a previous study was used in this analysis. Twenty-one main criteria were considered, and the sites were ranked to determine which was most desirable. Site 4 was found to be most suitable, followed by site 3

Knowledge about the effects of snake venoms on endocrine glands in the Kingdom of Saudi Arabia (KSA) is meager. The aim of the present study is to investigate the acute and chronic envenomation from 4 snakes out of 8 species of Saudi Cobras and Vipers on the tissues of endocrine glands and peripheral hormonal levels in male rats. The peripheral blood levels of 4 hormones mainly testosterone, cortisol, insulin and thyroxin were investigated in male Wistar rats following acute and chronic treatment of the rats with poisonous snake venoms at the Department of Physiology, Faculty of Medicine, King Abdul-Aziz University, Jeddah, Kingdom of Saudi Arabia between September 2000 to May 2001. Using radio immunoassay for hormonal analysis, a rise in testosterone levels in peripheral blood was obtained following acute treatment, which is due to the effect of the venoms on vascular permeability and increased blood flow. In contrast, the chronic treatment with venoms resulted in a delayed effect on vascular permeability and testicular degeneration resulting in a decreased blood flow and a significant drop in testosterone concentration. Cortisol levels were no different from the controls during acute treatment but it demonstrates gradual rise following chronic treatment to withstand the stress imposed on the animals. Similar results were obtained for insulin, which showed normal values with acute treatment but decreased levels of chronic treatment suggesting insulin insufficiently. Likewise, the thyroxin levels were decreased with chronic treatment suggesting a toxic effect of the poison on the rich blood supply of the thyroid follicles with a subsequent decrease in blood flow to the tissues and therefore, decreased thyroid hormone levels. The effects of venom toxicity on testosterone levels were either normal or stimulatory with acute treatment or inhibitory with chronic treatment depending on the vascular blood flow and testicular degeneration. Cortisol levels were normal at

Subsurface intake systems: Green choice for improving feed water quality at SWRO desalination plants, Jeddah, Saudi Arabia

KAUST Repository

Dehwah, Abdullah

2015-10-25

An investigation of three seawater reverse osmosis facilities located along the shoreline of the Red Sea of Saudi Arabia that use well intake systems showed that the pumping-induced flow of raw seawater through a coastal aquifer significantly improves feed water quality. A comparison between the surface seawater and the discharge from the wells shows that turbidity, algae, bacteria, total organic carbon, most fractions of natural organic matter (NOM), and particulate and colloidal transparent exopolymer particles (TEP) have significant reductions in concentration. Nearly all of the algae, up to 99% of the bacteria, between 84 and 100% of the biopolymer fraction of NOM, and a high percentage of the TEP were removed during transport. The data suggest that the flowpath length and hydraulic retention time in the aquifer play the most important roles in removal of the organic matter. Since the collective concentrations of bacteria, biopolymers, and TEP in the intake seawater play important roles in the biofouling of SWRO membranes, the observed reductions suggest that the desalination facilities that use well intakes systems will have a potentially lower fouling rate compared to open-ocean intake systems. Furthermore, well intake system intakes also reduce the need for chemical usage during complex pretreatment systems required for operation of SWRO facilities using open-ocean intakes and reduce environmental impacts.

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

Merging Approaches to Explore Connectivity in the Anemonefish, Amphiprion bicinctus, along the Saudi Arabian Coast of the Red Sea

2013-09-01

The field of marine population connectivity is receiving growing attention from ecologists worldwide. The degree to which metapopulations are connected via larval dispersal has vital ramifications for demographic and evolutionary dynamics and largely determines the way we manage threatened coastal ecosystems. Here we addressed different questions relating to connectivity by integrating direct and indirect genetic approaches over different spatial and ecological scales in a coral reef fish in the Red Sea. We developed 35 novel microsatellite loci for our study organism the two-band anemonefish Amphiprion bicinctus (Rüppel 1830), which served as the basis of the following approaches. First, we collected nearly one thousand samples of A. bicinctus from 19 locations across 1500 km along the Saudi Arabian coast to infer population genetic structure. Genetic variability along the northern and central coast was weak, but showed a significant break at approximately 20°N. Implementing a model of isolation by environment with chlorophyll-a concentrations and geographic distance as predictors we were able to explain over 90% of the genetic variability in the data (R2 = 0.92). For the second approach we sampled 311 (c. 99%) putative parents and 172 juveniles at an isolated reef, Quita al Girsh (QG), to estimate self-recruitment using genetic parentage analysis. Additionally we collected 176 juveniles at surrounding locations to estimate larval dispersal from QG and ran a biophysical dispersal model of the system with real5 time climatological forcing. In concordance with model predictions, we found a complete lack (c. 0.5%) of self-recruitment over two sampling periods within our study system, thus presenting the first empirical evidence for a largely open reef fish population. Lastly, to conceptualize different hypotheses regarding the underlying processes and mechanisms of self-recruitment versus long-distance dispersal in marine organisms with pelagic larval stages, I

The aim of this study was to prepare iron as solid lipid nanoparticles, in order to find an innovative way for alleviating the disadvantages associated with commercially available tablets. These limitations include adverse effects on the digestive system resulting in constipation and blood in the stool. The second drawback is the high variability in the absorption of iron and thus in its bioavailability. Iron solid lipid nanoparticles (Fe-SLNs were prepared by hot homogenization/ultrasonication. Solubility of ferrous sulfate in different solid lipids was measured, and effects of process variables such as the surfactant type and concentration, homogenization and ultrasonication times, and charge-inducing agent on the particle size, zeta potential, and encapsulation efficiency were determined. Furthermore, in vitro drug release and in vivo pharmacokinetics were studied in rabbits. Results indicated that Fe-SLNs consisted of 3% Compritol 888 ATO, 1% Lecithin, 3% Poloxamer 188, and 0.2% dicetylphosphate, with an average particle size of 25 nm with 92.3% entrapment efficiency. In vivo pharmacokinetic study revealed more than fourfold enhanced bioavailability. In

Modern sedimentary facies, depositional environments, and major controlling processes on an arid siliciclastic coast, Al qahmah, SE Red Sea, Saudi Arabia

The facies and environments along the arid siliciclastic coast of Red Sea in Al Qahmah, Saudi Arabia are studied to establish a depositional model for interpretation of ancient rocks deposited in rift settings. Field and petrographic studies of 151 sediment samples in an area of 20 km2 define seven main facies types: beach, washover fan, tidal channel, dune, sabkha, delta, and wadi (seasonal stream). The wadi and delta facies are composed of poorly to moderately well-sorted, gravelly, medium-to-fine sands. Delta-front sands are redistributed by southward longshore currents to form a beach. Beach facies is composed of well-to-moderately sorted fine sands with minor gravels, which contain high concentrations of magnetite, ilmenite, garnet, pyroxene, amphibole, epidote, titanite, and apatite grains, indicating strong winnowing. Crabs and other burrowers destroy primary sedimentary structures and mix sediments in foreshore and backshore of the beaches. Wind and storm surge rework foreshore and backshore sediments to form washover fans. Sabkha facies occurs extensively in supratidal depressions behind beach, are flooded by rainstorms and spring tide, and capped by a 5-cm-thick crust composed of interlaminated halite, quartz, albite, minor gypsum and biotite, and rarely calcium carbonate. Halite occurs as thin sheets and gypsum as nodules with a chicken-wire structure. Clastic fraction in sabkha sediments ranges from coarse silt to coarse sand with moderate sorting, and is transported by currents and wind. Tidal inlets and tidal creeks assume abandoned wadis and are filled by muddy sand. Sand dunes and sand sheets are 1-7 m high and widely distributed due to variable wind directions. Fine-grained dune sands are moderately well sorted, whereas sheet sands are coarser and poorly sorted due to vegetation baffling. Most eolian sands are sourced from beach deposits. This suite of complex riverine, wave, tidal, wind, chemical, and biological processes form the facies mosaic

GC and GC-MS characterization of crude oil transformation in sediments and microbial mat samples after the 1991 oil spill in the Saudi Arabian Gulf coast

Garcia de Oteyza, T.; Grimalt, J.O.

2006-01-01

The massive oil discharge in the Saudi Arabian coast at the end of the 1991 Gulf War is used here as a natural experiment to study the ability of microbial mats to transform oil residues after major spills. The degree of oil transformation has been evaluated from the analysis of the aliphatic and aromatic hydrocarbons by gas chromatography (GC) and GC coupled to mass spectrometry (GC-MS). The oil-polluted microbial mat samples from coastal environments exhibited an intermediate degree of transformation between that observed in superficial and deep sediments. Evaporation, photo-oxidation and water-washing seemed to lead to more effective and rapid elimination of hydrocarbons than cyanobacteria and its associated microorganisms. Furthermore, comparison of some compounds (e.g. regular isoprenoid hydrocarbons or alkylnaphthalenes) in the oil collected in the area after the spill or in the mixtures retained by cyanobacterial growth gave rise to an apparent effect of hydrocarbon preservation in the microbial mat ecosystems. - Cyanobacterial mats inhibit degradation of oil by reducing exposure to the atmosphere and seawater

The present work is a part of a project dedicated to measure the marine radioactivity near the Saudi Arabian coasts of the Red Sea and Arabian Gulf for establishing a marine radioactivity database, which includes necessary information on the background levels of both naturally occurring and man-made radionuclides in the marine environment. Farasan Islands is a group of 84 islands (archipelago), under the administration of the Kingdom of Saudi Arabia, in the Red Sea with its main island of Farasan, which is 50 km off the coast of Jazan City. The levels of natural radioactivity of (238)U, (235)U, (226)Ra, (232)Th and (40)K and man-made radionuclides such as (137)Cs in the grab sediment and water samples around Farasan Island have been measured using gamma-ray spectroscopy. The average activity concentrations of (238)U, (235)U, (226)Ra, (232)Th, (40)K and (137)Cs in the sediment samples were found to be 35.46, 1.75, 3.31, 0.92, 34.34 and 0.14 Bq kg(-1), respectively.

In Saudi Arabia, personal protective equipment must meet global standards for infection control, but the country’s Islamic legislature also needs to be taken into account. Aim: To assess uniform-related infection control practices of a group of dental students in a dental school in Saudi Arabia and compare the results with existing literature related to cross-contamination through uniforms in the dental field. Method: A questionnaire was formulated and distributed to dental students at King Abdulaziz University Faculty of Dentistry in Jeddah, Saudi Arabia, which queried the students about their uniform-related infection control practices and their methods and frequency of laundering and sanitizing their uniforms, footwear, and name tags. Results: There is a significant difference between genders with regard to daily uniform habits. The frequency of uniform washing was below the standard and almost 30% of students were not aware of how their uniforms are washed. Added to this, there is no consensus on a unified uniform for male and female students. Conclusion: Information on preventing cross-contamination through wearing uniforms must be supplied, reinforced, and emphasized while taking into consideration the cultural needs of the Saudi society. Keywords: cross-contamination, infection control, dental students, uniforms

Objectives: To assess preparedness for medical emergencies in private dental offices in Jeddah, Kingdom of Saudi Arabia (KSA). Methods: In this cross-sectional study, a survey was distributed to 70 dental offices and polyclinics in Jeddah, Saudi Arabia between October 2013 and January 2014. The questionnaire gathered information on the prevention of medical emergencies, the preparedness of the office personnel, and availability of emergency drugs and equipment. Results: For prevention, 92% (n=65) of the offices reported that they obtain a thorough medical history prior to treatment; however, only 11% (n=8) obtain vital signs for each visit. Using a preparedness percent score (0 to 100), the mean level of preparedness of the office personnel in all surveyed dental offices was 55.2±20. The availability of emergency drugs was 35±35, and equipment was 19±22. Conclusion: We found a deficiency in personnel training, availability of drugs, and emergency equipment in the surveyed dental clinics. More stringent rules and regulations for emergency preparedness must be reinforced to avoid disasters in these clinics. PMID:25737177

The intensity of infestation of the epizoic stalked barnacle Octolasmis on the blue crab was calculated for a total of 180 individuals collected around Jeddah, the western Red Sea Saudi coast. More than 90% of the crabs were found bearing the Octolasmis at a prevalence rate of 92% and mean intensity of 18.5±18.6 (0-127 epibiont per host). The intensity of infestation increased with host size in the range 90-135 mm. Generally, females were more infested (69%) than the males (31%). Octolasmis angulata occurred mostly on the gills, and the lower side of the gill chambers was more infested (84%) than the upper side (16%) and the left side of gills was also more infested than the right side in both males and females. Further studies are still needed to examine the commensal relationship and its impact on the fishery market of the Red Sea blue crab populations.

Full Text Available Background: Adequate sleep has been considered important for the adolescent′s health and well being. On the other hand, self-imposed sleep curtailment is now recognized as a potentially important and novel risk factor for obesity. The present study aimed to assess the prevalence of short sleep duration and its association with obesity among Saudi adolescents. Methods: This is a school-based cross-sectional study with self-reported sleep questionnaires. It was conducted during the years 2009/2010 in three cities in Saudi Arabia; Al-Khobar, Jeddah, and Riyadh. Participants were 2868 secondary-school males (1379 and females (1389 aged 15 to 19 years, randomly selected using a multistage stratified sampling technique. Measurements included weight, height, waist circumference, BMI, and sleeping duration. Logistic regression analysis while adjusted for age, gender, and location was used to examine the associations between sleep duration and obesity measures. Results: The mean (SD of sleep duration was 7.2 (1.6 hours/day with no significant differences between males and females. About 31% of the participants obtain less than 7 hours of sleep per day, while approximately 50% of the sample gets less than 8 hours of daily sleep. Two-way ANCOVA results while controlling for the effect of age revealed a significant gender by school-type interaction (P<0.001. In addition, adequate sleep duration increased the odds of having normal weight (adjusted odds ratios = 1.28, 95% CI = 1.08-1.50, P = 0.003. Conclusion: The present study observed a high prevalence of short sleep duration among Saudi adolescents 15- to 19-year olds and that short sleep duration was significantly associated with increased risk of overweight and obesity. Future interventions should investigate whether adopting a healthy lifestyle by adolescents with short sleep duration would improve their sleeping habits or not.

In this novel study, we investigated the relationship between particulate levels and prevalence of MetS component abnormalities (hypertension, hyperglycemia, obesity in a recruited cohort (N = 2025 in Jeddah, Saudi Arabia. We observed significant associations between a 10 μg/m3 increase in PM2.5 and increased risks for MetS (Risk Ratio (RR: 1.12; 95% Confidence Interval (CI: 1.06–1.19, hyperglycemia (RR: 1.08; 95% CI: 1.03–1.14, and hypertension (RR: 1.09; 95% CI: 1.04–1.14. PM2.5 from soil/road dust was found to be associated with hyperglycemia (RR: 1.12; 95% CI: 1.06–1.19 and hypertension (RR: 1.11; 95% CI: 1.05–1.18, while PM2.5 from traffic was associated with hyperglycemia (RR: 1.33; 95% CI: 1.05–1.71. We did not observe any health associations with source-specific mass exposures. Our findings suggest that exposure to specific elemental components of PM2.5, especially Ni, may contribute to the development of cardiometabolic disorders.

Objectives: To compare follicular reduction prior to human chorionic gonadotropin (HCG) trigger and coasting in terms of ovarian hyper-stimulation syndrome (OHSS) reduction, pregnancy, and cancellation rates in in vitro fertilization/ intracytoplasmic sperm injection (IVF/ICSI) cycles. Methods: This study was designed as a prospective study. The setting was the IVF unit at King Abdulaziz Medical City, Riyadh, Kingdom of Saudi Arabia. A total of 39 patients undergoing IVF/ICSI cycles, who were at risk of OHSS, 20 were put into a coasting group and 19 had follicular reduction instead. This occurred between October 2010 and January 2011. Our main outcome was OHSS reduction. Results: Six (30%) women developed OHSS in the coasting group and 2 (10.5%) women developed OHSS in the follicular group (p-value=0.235). The pregnancy rates in the cycles were similar for both groups: 4/20 (20%) in the coasting group and 3/19 (15.8%) in the follicular group (p-value=1.000). The cancellation rate of the cycles was similar for both groups, 6/20 (30%) in the coasting group and 1/19 (5.3%) in the follicular group (p-value=0.09). The median number of punctured follicles was significantly lower in the follicular group (16 follicles, interquartile range (IQR)=21-12) compared to the coasting group (29 follicles, IQR=37.8-19.8, p-value=0.001). The retrieved, fertilized, and cleaved oocytes, as well as the number of embryos transferred, were similar amongst both groups. Conclusion: There was no difference between follicular reduction prior to HCG and coasting, in terms of OHSS reduction, pregnancy, and cancellation rates in both the IVF and ICSI cycles.

Bazarbashi, Shouki; Al Eid, Haya; Minguet, Joan

2017-09-27

Background: In order to most appropriately allocate healthcare and research funding for cancer, it is important to have accurate population-based incidence data. The Saudi Cancer Registry (SCR) provides such information, covering the time period from 1994 to the present day. The current report concerns an overview of cancer incidence statistics for Saudi Arabia in 2012. Methods: The SCR collects data from healthcare facilities throughout the Kingdom of Saudi Arabia. All newly diagnosed cases of cancer are recorded, with information on site and histology. For the present report, age-standardised and age-specific incidence rates (ASR, AIR, respectively) were calculated, with attention to gender-specific and regional differences. Results: The total number of incident cases of cancer identified by the SCR in 2012 was 14,336, with 6,791 (47.5%) among males and 7,545 (52.6%) among females. Of this total, 11,034 cases (76.9%) occurred in patients of Saudi origin. For Saudi males, the overall ASR (inc. all cancer sites) was 78.1 per 100,000 people, while that for females was 86.7. Incidence varied by region, with the Eastern region and Riyadh displaying the highest ASRs for both males and females, and Hail and Jazan displaying the lowest. Incidence varied by gender, with colorectal cancer (13.3%), non-Hodgkin lymphoma (NHL; 8.4%), and leukaemia (8.2%) being the most common types in males, and breast (25.8%), thyroid (11.7%), and colorectal cancers (9.3%) being the most common in females. Conclusions: This analysis of cancer incidence in Saudi Arabia demonstrated significant differences according to gender, age, and region of the Kingdom. The data should help ensure the most appropriate allocation of resources, with the aim of minimising the healthcare burden associated with cancer. Creative Commons Attribution License

To study some ethical problems created by accession of a previously nomadic and traditional society to modern invasive medicine, by assessment of physicians' attitudes towards sharing information and decision-making with patients in the setting of a serious illness. Self-completion questionnaire administered in 1993. Riyadh, Jeddah, and Buraidah, three of the largest cities in Saudi Arabia. Senior and junior physicians from departments of internal medicine and critical care in six hospitals in the above cities. A total of 249 physicians participated in the study. Less than half (47%) indicated they provided information on diagnosis and prognosis of serious illnesses all the time. Physicians who were more senior and those who spoke Arabic fared better than other groups. The majority (75%) preferred to discuss information with close relatives rather than patients, even when the patients were mentally competent. Most of the physicians (72%) felt patients had the right to refuse a specific treatment modality, and 68% denied patients the right to demand such a treatment if considered futile. Further analysis showed that physicians' attitudes varied along a spectrum from passive (25%) to paternalistic (21%) with the largest group (47%) in a balanced position. In traditional societies where physicians are regarded as figures of authority and family ties are important, there is a considerable shift of access to information and decision-making from patients to their physicians and relatives in a manner that threatens patients' autonomy. Ethical principles, wider availability of invasive medical technology and a rise in public awareness dictate an attitude change.

To investigate the nursing shortage in Saudi Arabia and specifically the shortage of Saudi nurses in the healthcare workforce and to propose solutions. Literature published from 1993 to 2013 providing relevant information on the nursing shortage, cultural traditions and beliefs, and nursing education and policies in Saudi was accessed from multiple sources including Medline, CINAHL Plus and Google Scholar and from official Saudi government document and was reviewed. Saudi Arabia depends largely on an expatriate workforce, and this applies to nursing. Saudi Arabia is experiencing a nursing shortage in common with most countries in the world and a shortage of Saudi nationals, especially women, in the healthcare workforce. The world shortage of nursing is extrinsic to Saudi, but intrinsic factors include a poor image of the nursing profession in the country that is exacerbated by cultural factors. With the call for the Saudization of the workforce to replace the imported workforce by Saudi nationals, including nurses, through the 1992 Royal Decree, Saudi Arabia faces a problem in attracting and retaining Saudi nationals in the nursing workforce. Solutions are suggested that are aimed at improving the public image of nursing through education and the use of the media and improvements in the workplace by addressing working processes such as teamwork, ensuring adequate staffing levels and addressing some aspects of culture which may make working in nursing more compatible with being a Saudi national. © 2016 International Council of Nurses.

2008-01-01

Objective was to determine the prevalence of hyperlipidemia among Saudis of both genders in rural and urban communities. Selected Saudis in the age group of 30-70 years were studied over a 5-year period between 1995 and 2000 in Saudi Arabia. Data were obtained from history, physical examination and analysis of fasting plasma lipids. The data were analyzed to classify individuals with hypercholesterolemia (HC) (total cholesterol >=5.2 mmol/l) and hypertriglyceridemia (HT) (total triglycerides >=1.69 mmol/l). Logistic regression analysis was performed to provide a risk assessment model and correlation with other coronary artery disease (CAD) risk factors. The number of study samples included in the final analysis was 16,819. The prevalence of HC was 54% with mean cholesterol level of 5.4+-1.52 mmol/l. Prevalence of HC among males was 54.9% and 53.2% for females, while 53.4% among urban Saudis and 55.3% for rural Saudis. Hypertriglycemia prevalence was 40.3% with mean triglycerides level of 1.8+-1.29 mmol/l. Males had statistically significant higher HT prevalence of 47.6% compared to 33.7% in females (p<0.0001). Hyperlipidemia is reaching higher prevalence rates in KSA. This finding may suggest that CAD will soon be a major health problem. Reduction in obesity by adopting healthier eating problem habits and increasing physical activity are of considerable importance to our community. (author)

Deformation history of the Neoproterozoic basement complex, Ain Shams area, Western Arabian Shield, Saudi Arabia

El-Fakharani, Abdelhamid; Hamimi, Zakaria

2013-04-01

Ain Shams area, Western Arabian Shield, Saudi Arabia, is occupied by four main rock units; gneisses, metavolcanics, metasediments and syn- to post-tectonic granitoids. Field and structural studies reveal that the area was subjected to at least three phases of deformation (D1, D2 and D3). The structural features of the D1 are represented by tight to isoclinal and intrafolial folds (F1), axial plane foliation (S1) and stretching lineations (L1). This phase is believed to be resulted from an early NW-SE contractional phase due to the amalgamation between Asir and Jeddah tectonic terranes. D2 deformation phase progressively overprinted D1 structures and was dominated by thrusts, minor and major F2 thrust-related overturned folds. These structures indicate a top-to-the-NW movement direction and compressional regime during the D2 phase. Emplacement of the syn-tectonic granitoids is likely to have occurred during this phase. D3 structures are manifested F3 folds, which are open with steep to subvertical axial planes and axes moderately to steeply plunging towards the E, ENE and ESE directions, L3 is represented by crenulation lineations and kink bands. These structures attest NE-SW contractional phase, concurrent with the accretion of the Arabian-Nubian Shield (ANS) to the Saharan Metacraton (SM) and the final assembly between the continental blocks of East and West Gondwana.

Saudi Arabia is a country of the first importance because of its oil reserves (26% of the known world reserves) and its oil production: the third of the whole Opec production. This energetic gold mine finances up to 75% of the budget and assures 90% of its exports. The capacity of Saudi Arabia to refine crude oil is now comparable to that of France. Nevertheless the inflexibility of government expenditures makes foreign investors necessary to a balanced industrial development. It is expected that the Board of Trade soon presents some dispositions in order to promote and ease the opening to foreign investors. (A.C.)

To investigate dietary habits, lifestyle pattern and obesity in young university students. This cross-sectional study was performed at the Rabigh campus of King Abdulaziz University, Jeddah, Saudi Arabia, from March to May 2016, and comprised healthy male students. A close-ended questionnaire was filled by all students about their dietary habits and lifestyle pattern and the lipid profile, blood glucose levels and body mass index was determined. The participants were selected by convenience sampling method. SPSS 21 was used for data analysis. Of the 116 participants, 34(29.3%) were obese, 34(29.3%) were overweight and 48(41.4%) had normal body mass index. Overall, 66(57%) participants were taking 3 to 4 fast food meals weekly and was also taking junk food at least once in a day. Also, 50(43%) participants were using soft/energy drink more than once per day. Besides, 82(70.7%) respondents were spending 3 to 4 hours daily in watching TV, using the Internet or PlayStation. Significant differences were observed for low-density lipoprotein and high-density lipoprotein cholesterol levels (p=0.02 and p=0.006, respectively) among overweight and obese subjects as compared to those having normal weight. The majority of the overweight and obese participants' had experienced shame or other uncomfortable feelings and had a negative impact on their activity (p<0.001). Dietary habits and lifestyle of the majority of the participants were not up to the mark and the obesity prevalence was common.

2016-04-01

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

Burger, Joanna

2014-10-06

ABSTRACT: Fish are a healthful source of protein, but contaminants in some fish pose a risk. While there are multiple risk assessments from Europe and North America, there are far fewer for other parts of the world. We examined the risks from mercury, arsenic, lead, and other metals in fish consumed by people in Jeddah area, Saudi Arabia, using site-specific data on consumption patterns and metal levels in fish. The U.S. Environmental Protection Agency\\'s Hazard Quotient (HQ) and cumulative Hazard Index (HI) for non-cancer endpoints and Carcinogenic Index for cancer were used to determine the health risk based on fish consumption rates. Of the 13 fish species examined, HQ was greater than 1 (indicating elevated risk) in two species for arsenic, and seven species for methylmercury. The cumulative HI for all metals was above 1 for all but three species of fish at the mean consumption rates. Generally, fish species with HI above 1 for one sampling location, had HI above 1 for all sampling locations. The implications of these findings are discussed in the light of strategies for reducing risk from fish consumption while encouraging dietary intakes of fish with low mercury and arsenic levels.

The present study was conducted to establish cephalometric norms of Saudi boys based on the Steiners analysis, and to compare the results of the present study with similar studies conducted on other racial or ethnic groups. For this purpose, fifty-five healthy Saudi boys, with a mean age of 12.04 years, were selected from different schools of Riyadh. Female Saudis were not used for this study due to social restrictions with respect to the Kingdom's customs and traditions. Selection was made on the basis of normal occlusion, balanced and pleasing profile with no obvious facial asymmetry. None of the boys have undergone orthodontic treatment prior to this study. Lateral skull cephaiograms were taken and traced using a standardized technique. Each cephalogram was traced twice with a one week interval by the authors. All angular and linear measurements were calculated to the nearest 0.5 degree and 0.5 mm, respectively. Steiners method of cephalometric analysis was used to establish cephalometric norms. The result of the study demonstrated that the Saudi boys differed from other racial and ethnic groups in some skeletal and dental measurements. Generally, the Saudi boys revealed a more protrusive maxillary apical base and double dental protrusion. (author)

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

Ramli, Makbul A.M.; Twaha, Ssennoga; Al-Turki, Yusuf A.

2015-01-01

Highlights: • The performance of SVM and ANN in predicting solar radiation was investigated. • Optimum result was obtained with 16° and 37.5° tilt angles for Jeddah and Qassim. • RMSE, CC, and MRE statistical measures have been used to evaluate the performance. • SVM has significantly higher accuracy, is faster and robust during computation. - Abstract: In this paper, investigation of the performance of a support vector machine (SVM) and artificial neural networks (ANN) in predicting solar radiation on PV panel surfaces with particular tilt angles was carried out on two sites in Saudi Arabia. The diffuse, direct, and global solar radiation data on a horizontal surface were used as the basis for predicting the radiation on a tilted surface. The amount of data used is equivalent to 360 days, averaged from the 5-min basis data. By solving the tilt angle equation, an optimum value of solar radiation was obtained using a tilt angle of 16° and 37.5° for Jeddah and Qassim locations, respectively. The evaluation of performance and comparison of results of ANN as well as SVM and the measured/calculated data are made on the basis of statistical measures including the root mean square error (RMSE), coefficient of correlation (CC), and magnitude of relative error (MRE). The speed of computation of the algorithms is also considered for comparison. Results indicate that for Jeddah, the CC for SVM is between 0.918 and 0.967 for training and in the range of 0.91981–0.97641 for testing while that of ANN is in the range of 0.517–0.9692 for training and 0.0361–0.0961 for testing. For Qassim, the results are even better with CC of 0.999 for training and 0.987 for testing ANN showed higher values of MRE ranging between 0.19 and 1.16 and SVM is between 0.33 and 0.51 for training and testing respectively. In terms of speed of computation, it is observed that SVM is faster than ANN in predicting solar radiation data with a lower speed of 2.15 s compared to 4.56 s for ANN

Introduction: The current study aims to assess the level of patients’ satisfaction and the factors contributing to patients’ satisfaction toward family physicians (FPs) consultation, visiting primary healthcare centers (PHCCs) working under Ministry of Health, Jeddah. Materials and Methods: In this cross-sectional study conducted in Jeddah from November 1, 2016 to March 1, 2017, we used consultation satisfaction questionnaire and its four subscales with standard cutoffs. These subscales include general satisfaction, professional care, depth of relationship, and length of consultation. Mean scores along with standard deviation of these subscales were measured. Independent sample t-test, ANOVA, and multivariate regression analysis were performed to test the association between satisfaction level and predictors. Results: Overall, patients’ satisfaction was 60%. Around 74% of patients were satisfied with the professional care and 58% with the depth of the relationship. Around 60% of patients need more consultation time with the physicians. Knowledge about the presence of FP in the nearest PHCCs was around 70%. Multivariate regression analysis for the overall high satisfaction showed that the most important predictors of this high satisfaction level are regular visits to a particular FP (P < 0.001), distance from the PHCC (P = 0.044) and gender of the patient (P = 0.027). Conclusion: This study concluded that satisfaction with the FP's consultation is acceptable but needs improvement. Lower satisfaction was reported among males, patients living at a distance from PHCC and who had less knowledge about the presence of FP in their nearest PHCC. Such study data are vital for any corrective measures to boost satisfaction in patients attending PHCCs. PMID:29564270

Full Text Available Objectives: To review the incidence, spectrum of clinical manifestation, course, risk factors, as well as treatment of diabetes insipidus (DI following neurosurgery of the pituitary gland. Methods: The files of 24 patients that underwent neurosurgery for sellar lesions, or tumor near the hypothalamus or pituitary gland at the Department of Neurosurgery, King Abdulaziz University Hospital, Jeddah, Kingdom of Saudi Arabia were retrospectively reviewed between January 2011 to December 2014. A total of 24 patients were studied, and were divided into 2 groups namely; DI and non-DI. Patient characteristics were studied using descriptive statistics. The differences in proportion between the 2 groups were found out using Z-test for proportion in 2 populations. The mean differences in the hormonal abnormalities for the 2 groups were assessed using independent t-test. All statistics are considered statistically significant when p less than 0.05. Results: During hospitalization, 13 (54.2% out of 24 patient that underwent neurosurgery had manifestations of DI, which was transient in 5 (38.8% and permanent in 8 (61.2%. The DI subgroup contained higher prevalence of prolactinoma, craniopharyngioma, pre-operative panhypopituitarism, and macroadenoma in MRI imaging and transphenoidal surgery. Furthermore, urine osmolality was significantly lower in the DI group post-operatively with a significant p=0.023. It was recognized that the permanent DI documented more significant numbers than other studies. Conclusion: In our study group, it was recognized that permanent DI meant that our patients needed desmopressin for more than 3 months, which documented a more significant number than other studies.

The data of this work are based on the 'Saudi Maternal and Child Health Survey' conducted in 1991. This was a nationwide house to house field survey. The study included 6294 ever-married Saudi female in the childbearing age who represent the target population. They were randomly selected from both urban and rural settings of the five geographical areas of Saudi Arabia. The mean current age of the sample of ever-married women was 31 years and the mean age at first marriage was 17 and 16 years for urban and rural females, respectively. Education was associated with upward shift of the age at first marriage. About 20 per cent of the sampled ever-married Saudi females got married before their 15th birthday and 83 per cent before reaching 20 years of age. These percentages are even higher in rural than urban settings. The overall percentage of women who were currently married at the time of the survey was 96 per cent. The divorced and widowed women of childbearing age were 2 and 3 per cent, respectively, of the total. Husband's educational level had positive impact on the frequency of divorce. The latter was highest among women married to illiterate husbands with a dose response pattern. Comparison has been made with the situation 4 years ago. An increase in literacy rates among Saudi ever-married women and their husbands was observed, however, a significant (P < 0.05) difference still exists between female and male literacy rates (38 and 71 per cent, respectively). The events of early marriage, before the age of 15 years, became less frequent. There is an overall decline in teenage marriages which explains a large part of the recent changes observed in nuptiality and pattern of birth in Saudi Arabia.

The Red Sea is a unique ecosystem with high biodiversity in one of the warmest regions of the world. In the last five decades, Red Sea coastal development has rapidly increased. Sediments from continental margins are delivered to depths by advection and diffusion-like processes which are difficult to quantify yet provide invaluable data to researchers. Beryllium-7, lead-210 and ceseium-137 were analyzed from sediment cores from the near-coast Red Sea near Jeddah, Saudi Arabia. The results of this work are the first estimates of diffusion, mixing, and sedimentation rates of the Red Sea coastal sediments. Maximum chemical diffusion and particle mixing rates range from 69.1 to 380cm -2 y -1 and 2.54 to 6.80cm -2 y -1 , respectively. Sedimentation rate is constrained to approximately 0.6cm/yr via multiple methods. These data provide baselines for tracking changes in various environmental problems including erosion, marine benthic ecosystem silting, and particle-bound contaminant delivery to the seafloor.

Full Text Available The present study estimated the size-selectivity of Hipposcarus harid and Lethrinus harak caught in monofilament trammel nets of 50, 56, and 62 mm inner-panel mesh sizes. Fishing was carried out in the coral reef fisheries of Jeddah during the period from June 2013 to March 2014. The selectivity parameters were calculated using the SELECT method implemented in Pasgear 2 software. The normal location, normal scale, log-normal, gamma and bi-modal selectivity models were fitted to the data to estimate the selectivity curves. Results indicated that the log-normal model provided the best fit based on the lowest deviance value. Modal lengths estimated from the log-normal selectivity curves are: 19.73, 22.10, and 24.46 cm for H. harid, 18.41, 20.62, and 22.83 cm for L. harak caught with 50, 56 and 62 mm inner-panel mesh sizes, respectively. The length–girth relationship was estimated and described by the linear equation: G = 0.480 + 0.70 L (r2 = 0.95 for H. harid, and G = 0.73 L − 0.65 (r2 = 0.96 for L. harak. For proper management of H. harid and L. harak, the minimum inner-panel mesh size should be 62 mm to catch fish sizes larger than the length at maturity for both species.

The cost of domestic energy prices to Saudi Arabia

Alyousef, Yousef; Stevens, Paul

2011-01-01

The issue of subsidies on domestic energy prices has moved up the policy agenda, most recently as a result of the G20 commitment in September 2009 to phase out such subsidies. However, what constitutes a 'subsidy' is complex and controversial. The IEA in its last World Energy Outlook claimed that Saudi Arabia was second in the world in terms of its levels of subsidy on domestic energy prices. However, because Saudi Arabia is a price maker in the international oil market, the methodology used by the IEA is seriously flawed. This paper explains the problems with the methodology for computing subsidies and explains the correct method in the case of Saudi Arabia. It then attempts to measure the levels of subsidy in Saudi Arabia using this methodology. However, while it converts the IEA's 'subsidy' of $23 billion into a net 'profit' of $5.7 billion, it goes on to point out that the current low price regime is causing problems for Saudi Arabia. - Highlights: → How to define energy subsidies in the context of Saudi Arabia as the price maker for international oil prices? → How far do the low domestic energy price in Saudi Arabia represent subsidized prices? → What are the costs and benefits of low/subsidized domestic energy prices in Saudi Arabia? → What policy options are available to offset the very poor record of energy efficiency in Saudi Arabia?

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

Directory of Open Access Journals (Sweden)

Huraib S

2000-01-01

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

A pragmatic pairwise group-decision approach is applied to compare two regions in order to select the more suitable one for construction of nulcear power plants in the Kingdom of Saudi Arabia. The selection methodology is based on pairwise comparison by forced choice. The method facilitates rating of the regions or sites using simple calculations. Two regions, one close to Dhahran on the Arabian Gulf and another close to Jeddah on the Red Sea, are evaluated. No specific site in either region is considered at this stage. The comparison is based on a set of selection criteria which include (i) topography, (ii) geology, (iii) seismology, (iv) meteorology, (v) oceanography, (vi) hydrology and (vii) proximetry to oil and gas fields. The comparison shows that the Jeddah region is more suitable than the Dhahran region. (orig.)

The natural radiation levels in soil and sediment samples collected from floating water from a land runway resulting from heavy rains in the Jeddah region as well as the activity in the population of its surrounding environments were studied. In the regions surrounding Jeddah, the movements of floating water may increase the concentration of radioactivity due to the movement of soil due to heavy rains. In addition, the technological development of industry, agriculture and other sources around the Jeddah region has increased environmental pollution, resulting in noticeable concentrations of radioactivity. The measured activity concentrations of 214 Pb, 214 Bi, 228 Ac, 208 Tl, 40 K, 226 Ra and 228 Ra in the studied area suggest that they are within the world average for soils and sediments, except those for water sample no. 4; the concentration in this sample was five times higher than the world average concentration (this water is not consumable). Herein, the radioactivity concentrations that were obtained from the analysis of soil and sediment samples that were collected from the investigated area are discussed. Additionally, the absorbed dose rate (D), radium equivalent activity (Ra eq ), external hazard index (H ex ), annual gonadal dose equivalent (AGDE) and annual effective dose equivalent (AEDE) were evaluated. For the soil and sediment samples, the average radioactivity concentrations were determined for each site and are expressed in Becquerels per kilogram (Bq/kg) of dry weight, while for the measurement of both the 226 Ra and 228 Ra isotopes in the water samples, the activity concentration is expressed in picoCuries per liter (pCi/l). The obtained results were compared with other measurements from different countries. The movement of floating water around the Jeddah region increases the concentration of radioactivity due to the movement of soils with heavy rains. - Highlights: • The natural radiation levels in soil and sediment samples from floating

The Saudi government, similar to any other government, is committed to making public spending more efficient, using resources more effectively, and limiting waste. Health technology assessment (HTA) is a tool that informs policy and decision makers regarding the formulation of safe and effective policies that are patient-focused and help to achieve efficiency when allocating limited health-care resources. Areas covered: After a brief description of HTA in the international context, this review provides a brief introduction to Saudi Arabia's health-care system, followed by a delineation of the decision maker(s) and influencers and the decision-making process for pricing and reimbursement. The article then discusses the current status of HTA in Saudi Arabia and proposes four strategic objectives that can form the first step in the development of a formal HTA process. Expert commentary: In Saudi Arabia, facilitators for incorporating HTA into the decision-making process exist. Future local research is needed to guide the implementation of full HTA.

Full Text Available Introduction: The current study aims to assess the level of patients' satisfaction and the factors contributing to patients' satisfaction toward family physicians (FPs consultation, visiting primary healthcare centers (PHCCs working under Ministry of Health, Jeddah. Materials and Methods: In this cross-sectional study conducted in Jeddah from November 1, 2016 to March 1, 2017, we used consultation satisfaction questionnaire and its four subscales with standard cutoffs. These subscales include general satisfaction, professional care, depth of relationship, and length of consultation. Mean scores along with standard deviation of these subscales were measured. Independent sample t-test, ANOVA, and multivariate regression analysis were performed to test the association between satisfaction level and predictors. Results: Overall, patients' satisfaction was 60%. Around 74% of patients were satisfied with the professional care and 58% with the depth of the relationship. Around 60% of patients need more consultation time with the physicians. Knowledge about the presence of FP in the nearest PHCCs was around 70%. Multivariate regression analysis for the overall high satisfaction showed that the most important predictors of this high satisfaction level are regular visits to a particular FP (P < 0.001, distance from the PHCC (P = 0.044 and gender of the patient (P = 0.027. Conclusion: This study concluded that satisfaction with the FP's consultation is acceptable but needs improvement. Lower satisfaction was reported among males, patients living at a distance from PHCC and who had less knowledge about the presence of FP in their nearest PHCC. Such study data are vital for any corrective measures to boost satisfaction in patients attending PHCCs.

To identify the potential factors that would predict a dentist's awareness of domestic violence (DV), as well as the factors that influence the probability of dentists to take the required action. Also, to list the common barriers that dentists face when managing DV victims. Methods: In this cross-sectional study, a self-administered, structured questionnaire was sent randomly to dentists practicing in Jeddah, Saudi Arabia. The online survey link was emailed with a cover message that illustrated the study context. Responses were accepted from January 2016 until the end of February 2016. The Statistical Package for the Social Sciences version 22 was used for data analysis. Descriptive statistics, bivariate and multivariate analysis carried out to identify significant variables at p less than 0.05 level of significance.  Results: A sample size of 151 responses were recruited. The result of multivariate models indicated that the odds of dentists' awareness and taking actions towards DV victims were influenced by their education, clinical experience, gender, practicing sector, and qualification. Lack of training in identifying DV and embarrassment to bring up DV with patients were the most common barriers for the respondents when treating DV victims. Conclusion: Continuing education with regards to DV was found to be the most relevant predictor. More educational courses in this regard would empower dentists to support DV victims.

2014-01-01

Full Text Available Elements associated with total suspended particulate matter (TSP in Jeddah city were determined. Using high-volume samplers, TSP samples were simultaneously collected over a one-year period from seven sampling sites. Samples were analyzed for Al, Ba, Ca, Cu, Mg, Fe, Mn, Zn, Ti, V, Cr, Co, Ni, As, and Sr. Results revealed great dependence of element contents on spatial and temporal variations. Two sites characterized by busy roads, workshops, heavy population, and heavy trucking have high levels of all measured elements. Concentrations of most elements at the two sites exhibit strong spatial gradients and concentrations of elements at these sites are higher than other locations. The highest concentrations of elements were observed during June–August because of dust storms, significant increase in energy consumption, and active surface winds. Enrichment factors of elements at the high-level sites have values in the range >10~60 while for Cu and Zn the enrichment factors are much higher (~0–>700 indicating that greater percentage of TSP composition for these three elements in air comes from anthropogenic activities.

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.

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

Abstract : Vitamin D deficiency is widespread in Saudi Arabia. The aim of this study was to explore participants' knowledge about vitamin D and attitudes toward sun exposure. The study also aimed to explore the social and cultural factors that might potentially contribute to vitamin D deficiency in Saudi Arabia. Face-to-face interviews were carried out in the cities of Jeddah and Makkah between May and October 2015. The interview questions were semi-structured, and the data was analyzed using thematic analysis. Study participants showed a reasonable level of knowledge in different areas about vitamin D, including the effect of vitamin D deficiency on bone health and exposure to sunlight as the main source of vitamin D. Participants were also knowledgeable about vitamin D supplements as another source of this vitamin. Nevertheless, there was a shortage of knowledge in relation to dietary sources of vitamin D. In respect to attitudes toward sun exposure, some participants had positive attitudes toward sunlight and were willing to expose themselves to sunlight, but it was restricted to the early morning or late afternoon to avoid the heat. These participants who liked exposure to sunlight were largely exposing only their faces and hands to sunlight. Other participants had negative attitudes toward sun exposure and were avoiding sunlight. Moreover, the study participants identified several barriers to sun exposure, including hot climate, living in high-rise buildings, limited public areas allowing outdoor activities, lifestyle issues such as physical inactivity, and some religious concerns such as wearing the hijab. The study results also demonstrate that females were more enthusiastic about taking actions to improve their vitamin D status in comparison with males. Recommendations for health education interventions that increase awareness about vitamin D sources, especially food sources, are made. Also, educational interventions should focus on increasing awareness

In order to assess arsenic on the Tarut coast, Saudi Arabian Gulf, 38 sediment samples, 26 seawater samples and 40 gastropod and bivalve specimens were collected for analyses by Inductively Coupled Plasma-Mass Spectrometer. The Enrichment Factor (EF), the Geoaccumulation Index (Igeo) and the Contamination Factor (CF) indicated that coastal sediments of Tarut Island are severely enriched, strongly polluted and very highly contaminated with arsenic as a result of anthropogenic inputs. Comparison with arsenic in coastal sediments, seawaters and molluscs in the Red Sea, the Arabian Gulf and abroad coasts suggested that the studied samples have higher concentrations of As. The suggested natural sources of arsenic in the study area are the weathering and decomposition of neighboring deserts. The anthropogenic sources include the land reclamation, petrochemical industries, boat exhaust emissions, oil leakage, desalination plants and sewage effluents. These anthropogenic sources are the dominant sources of As in the study area and mostly came from Al Jubail industrial city to the north.

Interspecific and locational differences in metal levels in edible fish tissue from Saudi Arabia

KAUST Repository

Burger, Joanna

2014-07-06

Metal levels in fish have been extensively studied, but little data currently exists for the Middle East. We examined the levels of metals and metalloids (aluminum, arsenic, copper, manganese, selenium, zinc, and mercury) in the flesh of 13 fish species collected from three fishing sites and a local fish market in Jeddah, Saudi Arabia. We tested the following null hypotheses: (1) there are no interspecific differences in metal levels, (2) there are no differences in metal levels in fishes between market and fishing sites, (3) there are no size-related differences in metal levels, and (4) there are no differences in selenium:mercury molar ratio among different fish species. There were significant interspecific differences in concentrations for all metals. There was an order of magnitude difference in the levels of aluminum, arsenic, mercury, manganese, and selenium, indicating wide variation in potential effects on the fish themselves and on their predators. Fishes from Area II, close to a large commercial port, had the highest levels of arsenic, mercury, and selenium, followed by market fishes. Mercury was positively correlated with body size in 6 of the 13 fish species examined. Mercury was correlated positively with arsenic and selenium, but negatively with aluminum, cobalt, copper, manganese, and zinc. Selenium:mercury molar ratios varied significantly among species, with Carangoides bajad, Cephalopholis argus, Variola louti, and Ephinephelus tauvina having ratios below 10:1. These findings can be used in risk assessments, design of mercury reduction plans, development of fish advisories to protect public health, and future management decision-making.

With 266 billion barrels of proved oil reserves (16% of world total), Saudi Arabia holds the world's largest (conventional) crude oil reserves, was the largest exporter of total petroleum liquids in 2013, and the second largest petroleum liquids producer behind the United States. The Kingdom has the lion share of the global oil production spare capacity, which proved to be crucial for the oil market stability on many occasions in the past, allowing Saudi Arabia to replace missing barrels from any other oil producer in the world. In the same manner, Saudi Arabia's decision last November not to step-in and reverse the oil price decline thus, abandoning its historical role as a 'swing producer,' revived the old debate on the use of oil as a 'political weapon' on the international energy scene. In addition to its well-known predominant role in the oil markets and in the Organisation of Petroleum Exporting Countries (OPEC), several other features make the Kingdom of Saudi Arabia a major player in the world economy and global geopolitics. - Although the Kingdom does not export nor import natural gas, Saudi Arabia is embodied with the 5. natural gas proved reserves (8.2 trillion cubic meters (tcm), 4.4% of world natural gas proved reserves), behind Russia, Iran, Qatar and United States. With a production of 103 billion cubic meters (bcm), Saudi Arabia is also a gas producer solely for its domestic demand. - Because the Kingdom relies heavily on hydrocarbons for its present and future prosperity, the country is very active in climate change negotiations, as mitigation measures resulting from such negotiations will impact global oil demand. In the international talks on climate change, Saudi Arabia has often been calling for the need to address the vulnerabilities of the economies dependent on a single resource. - The Kingdom of Saudi Arabia is member of G20 Group, putting up-front oil producers' interests in a forum which accounts for 85

Oil - it is what has made Saudi Arabia rich. Without this black gold, none of the country's shopping malls, luxury hotels, six-lane highways or the airconditioned comfort that keeps the terrible heat at bay would be possible. From the first deposits harvested in the early 1950s, Saudi Arabia is now the world's leading exporter of petroleum, which accounts for nearly three-quarters of government revenue. And without the wealth from oil, the huge new King Abdullah University of Science and Technology (KAUST), built on hard, desert soil in less than two years, would have been impossible.

The average scattering and absorption coefficients at wavelength 525 nm were 109 ± 71 Mm- 1 (mean ± SD, at STP conditions) and 15 ± 17 Mm- 1 (at STP conditions), respectively. As expected, the scattering coefficient was dominated by large desert dust particles with low Ångström scattering exponent, 0.49 ± 0.62. Especially from February to June the Ångström scattering exponent was clearly lower (0.23) and scattering coefficients higher (124 Mm- 1) than total averages because of the dust outbreak season. Aerosol optical properties had clear diurnal cycle. The lowest scattering and absorption coefficients and aerosol optical depths were observed around noon. The observed diurnal variation 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). Positive Matrix Factorization mathematical tool was applied to the scattering and absorption coefficients and PM2.5 and coarse mode (PM10-PM2.5) mass concentrations to identify source characteristics. Three different factors with clearly different properties were found; anthropogenic, BC source and desert dust. Mass absorption efficiencies for BC source and desert dust factors were, 6.0 m2 g- 1 and 0.4 m2 g- 1, respectively, and mass scattering efficiencies for anthropogenic (sulphate) and desert dust, 2.5 m2 g- 1 and 0.8 m2 g- 1, respectively.

To determine factors that influence the job satisfaction of Saudi nurses. Saudi Arabia has a chronic shortage of Saudi national nurses. This research contributes to a greater understanding of how job satisfaction influences the recruitment and retention of Saudi nationals within the nursing profession. Qualitative data were gathered from Saudi nurses and content analysis was used to identify themes in the written responses. Four main themes emerged from the data: lack of educational opportunities and support and the poor image of the nursing profession, perceptions of favouritism, high workloads and stressful work environment and the effect of religion on job satisfaction. Saudi nurses would be more satisfied with their jobs if they had greater access to educational opportunities and if there was a reduction in workload and the perceived favouritism in the workplace was addressed. Religion was also found to play a significant role in supporting job satisfaction. These findings suggest the development of educational scholarships, as well as policies that better support equity in the workplace, to address Saudi nurses' level of job satisfaction. The generally positive impact of cultural and religious beliefs is also highlighted in this study. © 2015 John Wiley & Sons Ltd.

Renewed violent attacks in Saudi Arabia against the monarchy, combined with growing concern over royal corruption has led some analysts to predict that Saudi Arabia is likely to be "the next Iran"-that Islamist revolutionaries will come to power in Riyadh. I test this theory through the lens of network analysis in order to measure the degree of state-society integration in Pahlavi Iran and Saudi Arabia. My analysis finds that a) the Saudi state is far more integrated in society through so...

Pharmacovigilance is vital to public health. Adopting a robust spontaneous reporting system for adverse drug events can counteract most hazards that arise from utilizing medicinal products. Prior to the establishment of the Saudi Food and Drug Authority (SFDA), the number of pharmacovigilance-related activities in Saudi Arabia was limited. In 2009, the SFDA established the National Pharmacovigilance and Drug Safety Center (Saudi Vigilance). The pharmacovigilance system has remarkably improved during the past few years. Several initiatives have been taken to improve the program's performance. These initiatives include initiation of pharmacovigilance guidelines, enhancement of communication and reporting tools, training sessions for concerned staff and healthcare providers, and compliance from stakeholders. This review article provides an overview of what the Saudi Vigilance program is, focusing on the scope, mission and vision, hierarchy, operational themes, and overall work processes. Additionally, we will shed light on the challenges we encountered during the early phase and on our future plans.

Marine bacteria have been exceptional sources of halotolerant enzymes since decades. The aim of the present study was to isolate bacteria producing hydrolytic enzymes from seven different mangroves collected from the coastal area of Thuwal, Jeddah, Saudi Arabia, and to further screen them for other enzymatic and antifungal activities. We have isolated 46 different rhizo- and endophytic bacteria from the soil, roots, and leaves of the mangroves using different enzymatic media. These bacterial strains were capable of producing industrially important enzymes (cellulase, protease, lipase, and amylase). The bacteria were screened further for antagonistic activity against fungal pathogens. Finally, these bacterial strains were identified on the basis of the16S rDNA sequence. Taxonomic and phylogenetic analysis revealed 95.9-100% sequence identity to type strains of related species. The dominant phylum was Gammaproteobacteria (γ-Proteobacteria), which comprised 10 different genera - Erwinia, Vibrio, Psychrobacter, Aidingimonas, Marinobacter, Chromohalobacter, Halomonas, Microbulbifer, and Alteromonas. Firmicutes was the second dominant phylum, which contained only the genus Bacillus. Similarly, only Isoptericola belonged to Actinobacteria. Further these enzyme-producing bacteria were tested for the production of other enzymes. Most of the active strains showed cellulytic and lipolytic activities. Several were also active against fungal pathogens. Our results demonstrated that the mangroves represent an important source of potentially active bacteria producing enzymes and antifungal metabolites (bioactive products). These bacteria are a source of novel halophilic enzymes and antibiotics that can find industrial and medicinal use.

Large amounts of waste water are discharged daily from the Jeddah Metropolitan Area into the Red Sea. Sewage draining into the Red Sea causes widespread chemical pollution that is toxic to aquatic ecosystems. The objective of this study was to investigate the extent of pollution and assess the presence of heavy metals in fish tissue and study their association with biological and biochemical alterations. The average concentrations of heavy metals found in hepatic tissues of Variola louti fish from the polluted area, namely Cd, Cr, Cu, Fe and Zn, were 1.74, 9.69, 47.48, 4020.01 and 229.47 µg/g liver, respectively, that were significantly higher than that of samples taken from reference area (0.24, 1.98, 20.12, 721.93, 129.21 µg/g liver, respectively). The fold change of heavy metals in fish from the polluted area with respect of that of the reference area followed the order Cd > Fe > Cr > Cu > Zn. Analysis of nuclear DNA revealed that hepatic tissues of fish samples from the polluted area showed a significant increase in apoptotic cells as detected by flow cytometry and formation DNA-ladder. In addition, hepatic sections from polluted area fishes showed more fibrotic changes and collagen deposition by hematoxylin-eosin staining and Masson's trichrome staining, respectively, compared to samples taken from the reference area. Moreover, the electrophoretic patterns of proteins of liver of fishes caught at the polluted area showed different patterns of proteins from that of the reference with bands at 42, 130 and 140 kDa, which is in a good agreement with the molecular weight of collagen type III. In conclusion, there were significant changes in the tissues of fishes in the polluted area at the cellular and the molecular levels that may be associated with an accumulation of heavy metals. Assessment of fishes as a sensitive biomonitor for the pollution of surface waters that may affect general health of human and wild life is conceivable.

Mapping to assess feasibility of using subsurface intakes for SWRO, Red Sea coast of Saudi Arabia

KAUST Repository

Dehwah, Abdullah

2013-11-19

Use of subsurface intakes for seawater reverse osmosis desalination (SWRO) systems is known to improve raw water quality, reduce use of chemicals, improve operational reliability, and reduce the life cycle cost of desalination. A key issue in planning for the development of a SWRO facility that would potentially use a subsurface intake is the characterization of the coastal and nearshore geology of a region to ascertain the types of subsurface intakes that could be used and their respective costs. It is the purpose of this research to document a new methodology that can be used for planning and assessment of the feasibility of using subsurface intake systems for SWRO facilities at any location in the world. The Red Sea shoreline and nearshore area of Saudi Arabia were mapped and sediments were sampled from the Yemen border north of the Jordan border, a distance of about 1,950 km. Seventeen different coastal environments were defined, mapped, and correlated to the feasibility of using various types of subsurface intake systems. Six environments were found to have favorable characteristics for development of large-scale subsurface intakes. The most favorable of these coastal environments includes: (1) beaches and nearshore areas containing carbonate or siliciclastic sands with minimum mud concentrations and environmentally sensitive bottom community biota or fauna (A1, A2, and A3), limestone rocky shorelines with an offshore carbonate or siliciclastic sand bottom underlain by soft limestone and a barren area lying between the shoreline and the offshore reef (B1, B5), and wadi sediments on the beach (mixture of pebbles, gravel, and sand) with a corresponding nearshore area containing either siliciclastic sand and/or a marine hard ground (soft limestone or sandstone) (C2). It was found that seabed galleries were the subsurface intake type with the highest feasibility for development of large-capacity intakes. The geological characteristics of the offshore sea bottom

First dinosaurs from Saudi Arabia.

Directory of Open Access Journals (Sweden)

Benjamin P Kear

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

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

2015-12-01

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

Saudi Arabia this year is completing its expansion of production capacity and developing recent discoveries to enhance export flexibility. The 3 million b/d capacity expansion to 10 million b/d, announced in 1989, is on target for completion by year end 1994. Most of the effort involves restoration of mothballed production equipment and installation of several gas-oil separation plants (GOSPs) in existing fields. But Saudi Arabian Oil Co. (Saudi Aramco) also this year will start up production of extra-light oil from a new field in the central part of the kingdom. Start-up of Hawtah area production demonstrates success of an oil search Aramco began after receiving exclusive exploration rights to nearly all of Saudi Arabia's prospective area in 1986. From new fields and traditional producing areas, therefore, Saudi Arabia has the potential to expand production capacity beyond 10 million b/d. The paper describes the development of the extra capacity

Novel mutations underlying argininosuccinic aciduria in Saudi Arabia

Rashed Mohamed S

2010-03-01

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

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

Integrating Fisheries Dependent and Independent Approaches to assess Fisheries, Abundance, Diversity, Distribution and Genetic Connectivity of Red Sea Elasmobranch Populations

KAUST Repository

Spaet, Julia L.

2014-05-01

The Red Sea has long been recognized as a global hotspot of marine biodiversity. Ongoing overfishing, however, is threatening this unique ecosystem, recently leading to the identification of the Red Sea as one of three major hotspots of extinction risk for sharks and rays worldwide. Elasmobranch catches in Saudi Arabian Red Sea waters are unregulated, often misidentified and unrecorded, resulting in a lack of species-specific landings information, which would be vital for the formulation of effective management strategies. Here we employed an integrated approach of fisheries dependent and independent survey methods combined with molecular tools to provide biological, ecological and fisheries data to aid in the assessment of the status of elasmobranch populations in the Red Sea. Over the course of two years, we conducted market surveys at the biggest Saudi Arabian fish market in Jeddah. Market landings were dominated by, mostly immature individuals - implying both recruitment and growth overfishing. Additionally, we employed baited remote underwater video (BRUVS) and longline surveys along almost the entire length of the Red Sea coast of Saudi Arabia as well as at selected reef systems in Sudan. The comparison of catch per unit effort (CPUE) data for Saudi Arabian Red Sea BRUVS and longline surveys to published data originating from non-Red Sea ocean systems revealed CPUE values several orders of magnitude lower for both survey methods in the Red Sea compared to other locations around the world. Finally, we infered the regional population structure of four commercially important shark species between the Red Sea and the Western Indian Ocean.We genotyped nearly 2000 individuals at the mitochondrial control region as well as a total of 20 microsatellite loci. Genetic homogeneity could not be rejected for any of the four species across the spatial comparison. Based on high levels of region-wide exploitation, we suggest that, for management purposes, the population

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

Speciation and Mobility of Some Heavy Metals in the Coastal Sediments of Jeddah, Eastern Red Sea

International Nuclear Information System (INIS)

El-Sayed, Mohamed A.; Basaham, Ali S.

2004-01-01

Total and potentially mobile fractions of Fe, Mn, Cu, Zn and Pb were analyzed in 28 sediment samples collected from the coastal area of Jeddah. Sampling sites were selected from the coastal area of Jeddah. Sampling sites were selected to represent heavily sewage polluted areas and areas far from the effect of direct sewage dumping. Total concentrations reflected the degree of contamination and were particularly high in the confined environments. Concentrations in the mud fraction (<63um) were 3 to 6 times higher than that in the sand fraction. The repartition of elements between the exchangeable, reducible, oxidizable and residual fraction either as a constituent of the detrital material and/or trapped in the form of insoluble sulphides. Dominance of the exchangeable fraction characterized the speciation of Mn. Mobilization of Mn under reducing conditions and its readsorption on the particle surface is a probable explanation. Cu and Zn appear to have comparable distribution between the different fractions, however, Cu seems preferntially associated with the oxidizable fractions while reducing Zn was slightly more important than the other forms. Pb was particularly distributed between the oxidizable and the exchangeable fraction. Residual Pb participation was very low and sometimes totally absent. The interest behind the use of speciation schemes is that it permits the distinction between the fraction of the element that could be released into the water when the physico-chemical conditions are modified and the part that is permanently or quasi permanently fixed in the sediments. Most of the Fe was found held in the residual unavailable form while most of Mn, Cu, Zn and Pb were distributed between the environmentally unstable, exchangeable, oxidizable and reducible fractions. Therefore, these elements are supposed to have greater mobility and may, under particular conditions, greatly influence the environmental characteristics. (author)

Feasibility of Gallery Intake Systems for Seawater Reverse Osmosis Facilities along the Northern Red Sea Coast of Saudi Arabia

KAUST Repository

Dehwah, Abdullah

2012-03-01

The Kingdom of Saudi Arabia is dependent on desalination of seawater to provide new water supplies for the future. Desalination is expensive and it is very important to reduce the cost and lower the energy consumption. Most seawater reverse osmosis facilities use open-ocean intakes, which require extensive pre-treatment processes to remove particulate and biological materials that cause operating problems. An alternative intake is the subsurface system which utilizes the concept of riverbank filtration using wells or galleries and provides natural filtration to improve the quality of feedwater before it enters the desalination plant. This reduces operating cost and lowers energy consumption. Research was focused on evaluating gallery-type intakes (beach and seabed galleries) that could be used along the Northern Red Sea shoreline to provide a better quality feedwater for desalination. The geological characteristics of the visited sites were favorable for the development of seabed filter systems (offshore), but not for beach gallery intakes. The low wave energy along the shoreline and the presence of mud or rocky coasts made beach galleries infeasible. One of the potentially favorable sites for a seabed filter was located in the nearshore area at King Abdullah Economic City (KAEC). This site has a predominantly sandy offshore bottom with shallow water depths, and a low tide range. In addition, the bottom is always covered with water and contains soft limestone unit below the sand mantle that could be easy excavated to facilitate the construction of a seabed filter. About 50 sediment samples were collected from the site and laboratory measurements were performed on them. Grain size distribution, porosity and hydraulic conductivity measurements were performed on the sediment samples. In addition, six statistical methods were used to estimate the hydraulic conductivity values. Based on results of lab measurements, field observations, tide ranges and sediment types, it

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

Full Text Available Nowadays, many researchers focus on the relocation of the government in the transformation of The purpose of this study is to examine the role of Corporate Social Responsibility (CSR practices in higher education of Saudi Arabia. The growing importance of CSR has made it necessary for every university to use international benchmarks as standard to devise their CSR practices accordingly. This realization has shifted focus of CSR practices of Saudi universities towards every dimension of CSR. The study collected secondary data through 120 advertisements published from 2012 to 2015 and found out that CSR practices of universities of Saudi Arabia remain focused on social dimension of CSR because Saudi culture and religion had profound impact on business laws and eventually on CSR practices.

The aim is to study the incidence of thyroid cancer in surgically treated nodular thyroid disease, clinicopathological characteristics and treatment results. A retrospective review of 45 patients with thyroid malignancy at King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia during a 3-years period between January 2000 through to December 2003 was carried out. Analysis of clinicopathologic characteristics, age correlation to different risk factors, outcome of surgery and radioiodine treatment. A total of 120 thyroidectomies were performed during the 3-years period, January 2000 through to December 2003 at King Abdul-Aziz University Hospital. Forty-five (37.5%) patients had histopathology confirmed diagnosis of thyroid cancer. Eighty-two point two percent cases of papillary carcinoma, 4.4% follicular type and 6.7% anaplastic and medullary carcinoma of thyroid. Mean age was 40.5 +/- 14.8 years. Male preponderance was seen in this study with males: females ratio is 1.1:1. Nodular goiter was the most frequent presentation, observed in 30 (66.7%) cases. Fine needle aspiration cytology was suggestive of malignancy in 76% of cases. Ninety-seven patients with papillary carcinoma received ablative dose of radioiodine with average dose of 100-200 mCi. One female patient with follicular carcinoma of thyroid with bone, lung, and brain metastases received 4 doses of radioiodine with total dose of 800 mCi. Mortality rate was (2.2%), one patient died of complication of invasive anaplastic carcinoma with invasion of the trachea. There is a lot of controversy regarding thyroid malignancy investigations and management. We recommend that thyroid cancer patients should be treated by a team of endocrinologist, pathologist, experience thyroid surgeon, nuclear medicine and external radiotherapy physician to achieve an optimum care and good prognosis.

Health literacy has become a global issue, and it is important that patients and individuals are able to use information technology to access health information and educational services. The research objective is to develop a Saudi e-health literacy scale (SeHL) for measuring e-health literacy among Saudis suffering from non-communicable diseases (NCD). Overall, 14 relevant papers in related interdisciplinary fields were reviewed to select the most useful literacy dimensions. From these articles, we extracted the most common dimensions used to measure e-health literacy across the disciplines. Multiple workshops with multidisciplinary team members reviewed and evaluated items for SeHL. Four key aspects of e-health literacy-use of technology/media, information-seeking, usefulness and confidence-were identified and integrated as e-health literacy dimensions. These will be used to measure e-health literacy among Saudi patients with NCDs. A translation from Arabic to English was performed in order to ensure that translation process was accurate. A SeHL scale was developed to measure e-health literacy among Saudi patients. By understanding e-health literacy levels, we will be able to create a patient-education system to be used by patients in Saudi Arabia. As information technology is increasingly used by people of all ages all over the world, e-health literacy has been identified as a key factor in determining health outcomes. To date, no comprehensive scale exists to assess e-health literacy levels among speakers of Arabic, particularly among people with NCD such as diabetes, cardiovascular diseases and hypertension.

2006-01-01

The Saudi Cabinet of Ministers approved the Saudi General Environment System (SGES) in 2001. This approval is considered a step forward towards preserving the environment in Saudi Arabia. One of the targets of this system is to make environmental planning as an un-replaceable part of every comprehensive development planning in all industrial, agricultural, and architectural sectors. Achieving such a target requires a specialized labor force. Therefore, College of Engineering should act positively and actively in disseminating environmental awareness among engineers since they play a major rule in development projects. A degree in environmental engineering is a must at present, which is not available yet at any university in Saudi Arabia. Details of a B. Sc degree in environmental engineering offered by two universities in USA, are discussed. The syllabus of a degree in environment engineering adapted for the Saudi environment and culture is outlined

Full Text Available The main objective of this research is to study the role of energy consumption in economic growth in Saudi Arabia over the period of 1971–2012 using the autoregressive distributed lag (ARDL cointegration procedure, and based on neoclassical growth, endogenous growth, and ecological-economics viewpoints. Our empirical results show the existence of a cointegrating relationship between the different variables investigated. In addition, all the inputs (conventional and non-conventional Granger cause economic growth in both the short and long runs. Our findings confirm the energy-led growth hypothesis in the case of Saudi Arabia. Hence, energy conservation policies may deteriorate economic growth in Saudi Arabia if they are not followed by measures that improve energy efficiency, energy saving technologies and encourage the investment and use of renewable energy sources such as solar and wind energies that can participate in the attenuation of climate changes.

2006-01-01

Objective was to determine the negative appendectomy rate; utilization, accuracy of Alvarado scale, ultrasound (US), computed tomography (CT) in diagnosis of acute appendicitis. Hospital records of 124 female patients admitted for suspicious of acute appendicitis from January 2003-January 2004 to the Emergency Department (ED) at King Abdul-Aziz University Hospital Jeddah, Saudi Arabia were reviewed retrospectively. We reviewed the age of patients, clinical presentation, Alvarado scale, US, CT, histopathalogical diagnosis of appendicular specimen. A total of 124 female patients aged 6-64 years were presented to ED with right iliac fossa pain. Of the total, 103 patients have appendectomies (83.1%), 21 (16.9%) patients underwent conservative treatment. Prevalence of advanced appendicitis was 13.7% and negative appendectomy rate was 27.2%. Accuracy rate of appendicitis with Alvarado scale 67.7%, US was 57.9% CT was 66.7%. Postoperative correlation was found between advanced cases and Alvarado scale (r=0.338), and hospital stay duration (r=0.250, p<0.01). Clinical findings and experiments remain of major importance in appendicitis-diagnosis. When appendicitis appears with atypical presentations, it remains a clinical challenge. In such cases, laboratory and imaging investigation may be useful in establishing a correct diagnosis. Alvarado scoring system is easy, simple and cheap complementary aid for supporting the diagnosis of acute appendicitis especially for junior surgeons. (author)

Full Text Available Fish contamination has been extensively investigated along the Saudi coasts, but studies pertaining to bacterial pathogens are scarce. We conducted qualitative assessment and molecular identification of culture-dependent bacteria in 13 fish species from three coastal sites and a local fish market in Jeddah, Saudi Arabia. Bacterial counts of gills, skin, gut and muscle were examined on agar plates of Macconkey’s (Mac, Eosin Methylene Blue (EMB and Thiosulfate Citrate Bile Salts (TCBS culture media. Bacterial counts significantly differed between species, sources and feeding habits of examined fishes. Mugil cephalus exhibited higher counts on TCBS (all body parts, Mac (gills, muscle and gut and EMB (gills and muscle. Fishes from Area I had higher bacterial loads, coinciding with those in seawater and sediment from the same site, indicating direct association between habitat conditions and the levels of bacterial contamination. By feeding habit, detritivorous fish harbored higher counts than herbivorous and carnivorous species. Bacterial counts of skin were higher in fish from market than field sites, and positively correlated with other body parts indicating the relation of surface bacterial load on the overall quality of fish. Rahnella aquatilis (Enterobacteriaceae and Photobacterium damselae (Vibrionaceae were among the dominant species from fish muscle based on 16S rRNA sequencing. These species are known human pathogens capable of causing foodborne illness with severe antibiotic resistance. Opportunistic pathogens, e.g. Hafnia sp. (Enterobacteriaceae and Pseudomonas stutzeri (Pseudomonadaceae also occurred in fish muscle. The inclusion of bacterial contamination in future monitoring efforts is thus crucial.

2018-04-06

To appraise and synthesise existing literature on nurse turnover in the Saudi Arabian context. Saudi Arabia is notably one of the nations with a health care system that is bombarded by high rates of turnover and turnover intention. Moreover, rapid population growth and the expansion of the health care system increase the demand on registered nurses in the kingdom. Eleven primary sources were reviewed using Whittemore and Knafl's (Journal of Advanced Nursing, 2005; 52, 546-553) integrative review method. There is variation in the reported turnover rates across the studies. The identified determinants of nurse turnover in the Saudi Arabian context included nurses' demographics, satisfaction, leadership and management, and job-related factors. There is a need for more studies that focus on the cost and outcome of nurse turnover and turnover intention in the Saudi Arabian context. The review highlights the alarming rates of nurse turnover and its determinants in Saudi Arabia. Nurse managers in Saudi Arabia should consider this information, as they make daily assignments. © 2018 John Wiley & Sons Ltd.

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

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

Full Text Available Background The ages of onset of pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors; however, due to lack of country-specific norms, clinicians in Saudi Arabia use Western estimates as standards of reference for local children. Aims The aim of the Riyadh Puberty Study was to provide data on pubertal development to determine the average age of onset of pubertal characteristics among Saudi boys. Methods Cross-sectional study among male school children in Riyadh, Saudi Arabia, in 2006, 542 schoolboys, aged 6 to 16 years old, from diverse socioeconomic levels were selected into the sample using a cluster sample design. Tanner stages were ascertained during physical examination by pediatric endocrine consultants, and also trained pediatric residents and fellows. Results The mean age (standard deviation at Tanner Stages 2, 3, 4, and 5 for pubic hair development of Saudi boys was 11.4 (1.6, 13.3 (1.3, 14.4 (1.0 and 15.1 (0.8 years old, respectively.

Full Text Available Water column conditions in a lagoon near Jeddah are investigated on the basisof changes in potential energy. Three major factors including balance ofsurface heat at the air-sea interface, wind and tidal mixing are considered.A negative potential energy change dv/dt will developstratification, whereas positive dv/dt will tend to mix the watercolumn. The tidal effect is greater in summer with wind mixing showing nogreat variations. The buoyancy effect of the heat balance at the surface isnegative from April to October. This negative buoyancy effect will tend to developstratification but the positive contributions of wind and tide counteract this andthe water column remains mixed except in September and October, when a weakstratification may develop. Generally, the water column remains practically mixedthroughout the year. The change in heat content of the water column from mid-Aprilto mid-September is about 3.3 × 108 J. During this period the netheat input at the air interface is about 2.0 × 108 J, which isabout 40% less than the heat content of the water column, showing that the heat is advected towards the central area from the shallower periphery of the lagoon.

2011-08-01

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

Blood pressure levels may vary in children because of genetic, ethnic and socioeconomic factors. To date, there have been no large national studies in Saudi Arabia on blood pressure in children. Therefore, we sought to establish representative blood pressure reference centiles for Saudi Arabian children and adolescents. We selected a sample of children and adolescents aged from birth to 18 years by multi-stage probability sampling of the Saudi population. The selected sample represented Saudi children from the whole country. Data were collected through a house-to-house survey of all selected households in all 13 regions in the country. Data were analyzed to study the distribution pattern of systolic (SBP) and diastolic blood pressure (DBP) and to develop reference values. The 90th percentile of SBP and DBP values for each age were compared with values from a Turkish and an American study. A total of 16 226 Saudi children and adolescents from birth to 18 years were studied. Blood pressure rose steadily with age in both boys and girls. The average annual increase in SBP was 1.66 mm Hg for boys and1.44 mm Hg for girls. The average annual increase in DBP was 0.83 mm Hg for boys and 0.77 mm Hg for girls. DBP rose sharply in boys at the age of 18 years. Values for the 90th percentile of both SBP and DBP varied in Saudi children from their Turkish and American counterparts for all age groups. Blood pressure values in this study differed from those from other studies in developing countries and in the United States, indicating that comparison across studies is difficult and from that every population should use their own normal standards to define measured blood pressure levels in children.

Habtoor, Abdelmonem; Ahmed, Ahmed Hassan; Harbi, Hesham

2016-10-01

The Makkah quadrangle is a part of the Jeddah terrane in the Precambrian basement, Western Arabian Shield of Saudi Arabia. Gabal Taftafan mafic-ultramafic complex lies within the central part of the Makkah quadrangle. The Taftafan mafic-ultramafic complex is a well-differentiated rock association which comprises of dunite core, hornblende- and plagioclase-bearing peridotites, troctolite, clinopyroxenite and marginal gabbro, in a distinctive zonal structure. The bulk-rock geochemistry of the Taftafan mafic-ultramafic rocks is characterized by a tholeiitic/sub-alkaline affinity with high Mg in the ultramafic core (0.84) and is systematically decreased towards the marginal gabbro (0.60). The patterns of trace elements show enrichment in the fluid-mobile elements (Sr, Ba) and a pronounced negative Nb anomaly which reflect a hydrous parental magma generated in a subduction tectonic setting. The mafic-ultramafic rocks of the Taftafan complex have low total rare earth elements (REE) displaying sub-parallel patterns leading to the assumption that these rocks are comagmatic and are formed by fractional crystallization from a common magma type. The platinum-group elements (PGE) content of all rock types in the Taftafan complex is very low, with ∑ PPGE > ∑ IPGE; displaying slightly positive slopes of the PGE distribution patterns. The chemistry of ferromagnesian minerals is characterized by a high forsterite (Fo) olivine with wide range (Fo91-67), from ultramafic core to the marginal gabbro, Ca-rich diopsidic clinopyroxene, and calcic hornblende. Orthopyroxene is almost absent from all rock types, or very rare when present. Hornblende and Ca-plagioclase possess the longest crystallization history since they are present in almost all rock types of the complex. Spinels in the dunite and hornblende-bearing peridotite core show homogeneous composition with intermediate Cr# (0.53-0.67). Plagioclase-bearing peridotite and troctolite have two exsolved types of spinel; Al

Shamsuddin Alaraki, Mohammad

The health care system in Saudi Arabia has serious problems with quality and safety that can be reduced through systematic quality improvement (QI) activities. Despite the use of different QI models to improve health care in Saudi hospitals during the last 2 decades, consistent improvements have not yet been achieved and the results are still far below expectations. This may reflect a problem in introducing and implementing the QI models in the local contexts. The objective of this study is to assess the extent of QI implementation in Saudi hospitals and to identify the organizational characteristics that make Saudi hospitals particularly challenging for QI. Understanding these characteristics can inform efforts to improve them and may lead to more successful implementation. A mixed-methods approach was conducted using 2 data collection tools: questionnaires and interviews. The quantitative phase (questionnaires) aimed to uncover the current level of QI implementation in Saudi hospital as measured by 7 critical dimensions adapted from the literature. The qualitative phase (interviews) aimed to understand the organizational characteristics that impede or underpin QI in Saudi hospitals. The QI implementation was found to be significantly poor across the 7 dimensions with average score ranging between 22.80 ± 0.57 and 2.11 ± 0.69 on a 5-point Likert scale and with P value of less than .05. We also found that the current level of QI implementation helped Saudi hospitals neither to improve "customer satisfaction" nor to achieve measurable improvements in "quality results" scoring significantly low at 2.11 ± 0.69 with P value of .000 and 2.47 ± 0.57 with P value of .000, respectively. Our study confirms the presence of a multitude of organizational barriers that impede QI in Saudi hospitals. These are related to organizational culture, human resources management, processes and systems, and structure. These 4 were found to have the strongest impact on QI in Saudi

Full Text Available Steroid resistant nephrotic syndrome (SRNS remains a challenge facing pediatric nephrologists. The underlying histopathology usually affects the course of the disease and the response to treatment. We studied the pattern of histopathology in children with SRNS who presented to the King Abdul Aziz University Hospital (KAUH, Jeddah, Saudi Arabia. The records of all children with primary SRNS, who were seen between 2002 and 2007 were reviewed. Only patients who had undergone a renal biopsy were included in the study. The histopathology slides were reviewed by two renal pathologists independently. Patients with congenital nephrotic syndrome, lupus or sickle cell disease, were excluded from the study. Thirty-six children fulfilled the inclusion criteria, and included 25 girls and 11 boys with female to male ratio of 2.3:1. Fifty percent of the children (n=18 were Saudi and the remaining 50% were from various other racial backgrounds (9 Asians, 4 Arabs, 2 Africans and 3 from the Far East. Their mean age at presentation was 4.3 ± 3.0 years (range 1-12 years. The mean serum albumin at presentation was 15.6 ± 7.1 g/L and all of them had 4+ proteinuria on urinalysis. Five children had elevated serum creatinine at presentation while the mean serum creatinine was 50.4 ± 45.6 µmol/L. Three children had low serum complement levels at presentation and none were positive for hepatitis B surface antigen or antinuclear antibody (ANA. The renal histopathology was compatible with focal and segmental glomerulosclerosis (FSGS in 39% (n=14, IgM nephro-pathy in 28% (n=10, mesengioproliferative glomerulonephritis (MesPGN in 17% (n=6, mini-mal change disease (MCD and C1q nephropathy (C1qNP in 8% each (n=3 + 3 and IgA nephro-pathy in 3% (n=1. Our retrospective review shows that FSGS was the commonest underlying histopathology in children who presented with SRNS followed by IgM nephropathy and other variants of MCD such as MesPGN. C1qNP was the underlying cause in some

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

1994-08-01

The 1970s and early 1980s saw the phenomenal growth and development of healthcare services in Saudi Arabia. This growth was unique in that it took place in a country that lacked basic infrastructure and trained personnel, but had recently acquired great wealth. Developments that took hundreds of years to occur in other countries took only 20 yrs to attain in Saudi Arabia. This growth posed unique challenges and required novel solutions. Recently, the country has had to cope with a drastic decrease in oil revenue, as well as cutbacks in healthcare funding. Now that the basic foundations of a national healthcare service have been constructed, it remains to be seen whether gains can be consolidated and steady progress made as more and more Saudi nationals take over and run their own public and private healthcare services.

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

To examine how nurse managers' leadership styles, and nurses' organisational commitment in Saudi Arabia relate. Effective leadership is influential in staff retention; however, recruiting and maintaining nurses is an increasing problem in Saudi Arabia. Using a survey design, the Multifactor Leadership Questionnaire and the Organisational Commitment Questionnaire were distributed to a sample of 219 nurses and nurse managers from two hospitals in Saudi Arabia. Transformational leadership was the most dominant leadership style. After controlling for the influence of manager/staff status, nationality and hospitals, transformational leadership was the strongest contributor to organisational commitment. Perceptions of both transformational and transactional leadership styles, increased with age for nurse managers and nursing staff. Introducing the Full Range of Leadership model to the Saudi nursing workforce could help to prepare Saudi nurses for positions as nurse managers and leaders. The study provides insight into the type of leadership that is best suited to the dynamic and changing health care system in Saudi Arabia. It is possible that transformational leaders could influence and induce positive changes in nursing. © 2018 The Authors. Journal of Nursing Management Published by John Wiley & Sons Ltd.

Research activities in Saudi Arabia are promoted at the governmental and institutional levels. However, the output and quality of research conducted in the field of neurology has not yet been measured quantitatively. This study therefore aimed to analyse neurology-related publications from Saudi Arabia. This study was conducted in January 2016. A systematic search using the PubMed ® search engine (National Library of Medicine, Bethesda, Maryland, USA) was conducted to identify all neurology-related articles published from Saudi Arabia between January 1996 and December 2015. A total of 1,292 neurology-related publications were identified. Neurology research increased linearly with time, with most publications originating from Riyadh (67%) and the university sector (≈47%). However, most neurology-related articles were published in journals which had an impact factor of Saudi Arabia has increased substantially over the last 20 years. However, as most articles were published in low-impact journals, the quality of research remains inadequate and should be improved. It is important that an official research culture be established in both governmental and private universities as well as colleges and health institutions in Saudi Arabia. The formation of clinical academic departments staffed by research experts is recommended to ensure the quality of neurology research output.

Full Text Available Research in Saudi Arabia has revealed a shocking level of insufficiently physically active adults, particularly women. The risk of sedentary behavior will likely increase as the number of women with office-based jobs increases. The aim of this study is to determine the level of sedentary behavior, and its associated factors, among Saudi women working office-based jobs in the city of Riyadh. A cross-sectional study of 420 Saudi female employees at 8 office-based worksites were measured to determine body mass index and were given a self-administered survey to evaluate their level of physical activity and sedentary behavior. Median sitting time on work days was 690 min per day (interquartile range, IQR 541–870, with nearly half accumulated during work hours, and 575 min per day (IQR 360–780 on non-work days. Predictors of work day sitting time were level of education, number of children, and working in the private sector. Number of children, whether they were single, and whether they lived in a small home were found to predict non-work day sitting time. This study identifies Saudi women in office-based jobs as a high-risk group for sedentary behavior. There is a need to promote physical activity at worksites and reduce prolonged sitting.

The World Health Organization (WHO) has reported that Saudi Arabia ranks the second highest in the Middle East, and is seventh in the world for the rate of diabetes. It is estimated that around 7 million of the population are diabetic and almost around 3 million have pre-diabetes. Even more worrying perhaps, is the increasing pattern of diabetes noted in Saudi Arabia in the recent past. In fact, diabetes has approximately registered a ten-fold increase in the past three eras in Saudi Arabia. Diabetes mellitus (DM) has been found to be related to high mortality, morbidity and vascular complications, accompanied by poor general health and lower quality of life. In Saudi Arabia, DM is quickly reaching disturbing proportions and becoming a significant cause of medical complications and even death. However, when compared with the developed countries, the research work conducted, focusing particularly on the incidence, prevalence and socio-demographic properties of DM is woefully inadequate. The health burden due to DM in Saudi Arabia is predicted to rise to catastrophic levels, unless a wide-ranging epidemic control program is incorporated, with great emphasis laid on advocating a healthy diet, including exercise and active lifestyles, and weight control. To properly manage the DM in Saudi Arabia, a multidisciplinary approach is required. In this review we discuss all the aspects of DM in Saudi Arabia drawing from the published literature currently available.

Essays on oil and business cycles in Saudi Arabia

Science.gov (United States)

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

We studied the association of single nucleotide polymorphisms (SNPs) rs7903146, rs12255372 and rs4506565 in type 2 diabetes mellitus (T2DM) susceptibility gene, transcription factor 7 like 2 (TCF7L2) with T2DM among the population of the Eastern Province of Saudi Arabia. In a case-control study, blood samples were collected from 359 T2DM patients and 351 age and sex-matched normoglycemic controls. Genotyping was done by allele specific PCR assay. Our results revealed a strong association between risk T alleles in variants rs12255372 (OR: G/T=1.4233; T/T=2.0395) and rs4506565 (OR: A/T=1.6066; T/T=3.1301) and T2DM among the Saudi population of the Eastern Province of Saudi Arabia. This is the first time that this association has been identified in a Saudi population. However, a common variant, rs7903146, often found to be associated with T2DM in other populations failed to demonstrate any association to T2DM with the present population. These data further strengthens the hypothesis that Saudi populations might carry a distinct risk allele in T2DM susceptibility gene TCF7L2. The present results confirm that rs12255372 and rs4506565 variants of TCF7L2 show an association, but not rs7903146, with T2DM for the Saudi population of the Eastern Province of Saudi Arabia.

We retrospectively reviewed Saudi patients who had a congenital disorder of glycosylation (CDG). Twenty-seven Saudi patients (14 males, 13 females) from 13 unrelated families were identified. Based on molecular studies, the 27 CDG patients were classified into different subtypes: ALG9-CDG (8 patients, 29.5%), ALG3-CDG (7 patients, 26%), COG6-CDG (7 patients, 26%), MGAT2-CDG (3 patients, 11%), SLC35A2-CDG (1 patient), and PMM2-CDG (1 patient). All the patients had homozygous gene mutations. The combined carrier frequency of CDG for the encountered founder mutations in the Saudi population is 11.5 per 10,000, which translates to a minimum disease burden of 14 patients per 1,000,000. Our study provides comprehensive epidemiologic information and prevalence figures for each of these CDG in a large cohort of congenital disorder of glycosylation patients. © 2017 Wiley Periodicals, Inc.

The study adopted the descriptive analytical approach by using a questionnaire to collect data. The researcher developed the questionnaire which consisted of (46 items and were distributed over four themes. The questionnaire was checked for its validity and reliability. Then, it was administrated to a sample of (80 faculty members in the education faculty at Jeddah University. The findings of the study were as follows: The effect of university and society obstacles on academic productivity was given a high rate. On the other hand, the effect of personal obstacles and academic publication received an average rate. The society obstacles were ranked first, while academic publication obstacles were in the last rank. There were statistically significant differences which were attributed to the differences in academic rank in the obstacles related to university, society and personal and academic publication in favor of the assistant professor rank. There were also statistically significant differences that were attributed to years of experience in university obstacles in favor of (1-5 years experience and (more than 10 years experience. On the other hand, there were no differences in university, society and personal obstacles. There were no statistically significant differences attributed to the variable of the university from which the faculty members got their PhD degree. In addition, there were statistically significant differences attributed to nationality in university, personal and society obstacles while there were no differences in the variable of academic publication. The study recommended the need to increase funds to be allocated for academic productivity. Keywords: Academic productivity, Faculty members, Obstacles, Universities.

The primary aim of this study was to investigate the effect of birth intervals on some aspects of intellectual ability of Saudi primary school boys. This is a cross-sectional study of Saudi school children comparing their intellectual ability (general intelligence) in relation to the length of the birth interval before and after the birth of the index child. The study area comprised 3 townships in the eastern province; Khobar, Thogba and Dhahran. The study was conducted in 2000/2001 and the study population comprised Saudi primary school boys aged 9-10 years from a middle class background. A 2 stage random sampling technique was adopted. Data were collected using student data sheet, a family questionnaire and the Standard Progressive Raven Matrices Test of intellectual ability, standardized for use in Saudi Arabia. Data were analyzed using SPSS software. More than 90% of children born after a birth interval greater than 35 months were classified as average and above according to the Raven Matrices Test, compared to 79% of children born after a birth interval of less than 19 months (pRaven Matrices Test to be family income and height. Longer birth intervals were shown to be associated with higher general intelligence levels in the 9-10 year olds. These results confirm those obtained in a previous study in Singapore conducted more than 2 decades ago. Our results have also shown that the succeeding birth interval is more significant than the preceding interval in relation to perceptive ability of children. The findings enable us to advise parents that by observing a birth interval between 2-3 years would make their children grow and do better at school.

Successful restoration of degraded habitats requires information about the history and factors led to the deterioration of these habitats. This study analyzed SaudiVeg Ecoinformatics, which is a big phytosociological database about plant communities and other environmental factors affecting them in the Najd-Central Region of Saudi Arabia. A phytosociological survey with more than 3000 vegetation relevés was conducted during 2013. The data were used to correlate the plant community attributes, such as abundance and species diversity in natural and ruderal habitats with environmental factors, such as human impacts, soil physical and chemical properties, and land uses. The data were subjected to multivariate analyses using programs, such as TWINSPAN, DCA and CCA, via Juice package. Fourteen vegetation associations were described under provisional classification of the Central Saudi Arabia deserts. These associations were broadly grouped into desert vegetation types. One alliance group, Haloxylonion salicornici, is the most widespread and contains four associations on the wadis and desert plains. Three associations are dominant on the depression habitats (raudhas) and two associations of Tamarixidetum spp. on the wetland and salt pan habitats. Four associations inhabit the man-made habitat and abandoned field habitats and one association, the Neurado procumbentis-Heliotropietum digyni, dominates the overgrazed sandy dunes. As human impact is huge and increasing, the vegetation ecoinformatics of the present study would form a baseline description that could be used as a vital tool for future monitoring and for proposing environmental restoration processes in central Saudi Arabia. It could also help both Governmental and Non-governmental organizations (NGO) in formulating strategies and on-ground plans for protection, management and restoration of the natural vegetation.

Conservation in the Kingdom of Saudi Arabia is relatively young, yet have made considerable gains in conservation through strategic proclamation and reintroductions. Changes in land use, illegal hunting and competition with domestic stock has decimated the native ungulates, meaning that the survival of the native ungulate species is now completely dependent on protected area network. The challenge is to sustain this network to make meaningful conservation impact into the future. We review the status of ungulate conservation in Saudi Arabia and highlight that the conservation strategy is well developed. The major challenge faced in conservation in Saudi Arabia now is to implement what has been sanctioned.

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

Full Text Available Many diseases are compromising fig production in Saudi Arabia and in particular those caused by viruses. RT-PCR assays were conducted on 80 samples collected from four fig-growing provinces in the West Mecca region of Saudi Arabia, including the Fatima, Khulais, Rabigh and Alshifa valleys. Samples consisted of leaf tissues taken from caprifig and common fig trees. The presence of Fig mosaic virus (FMV, Fig leaf mottle-associated virus 1 (FLMaV-1, Fig leaf mottle-associated virus 2 (FLMaV-2 and Fig mild mottle-associated virus (FMMaV was assessed from the samples. RT-PCR results showed that all four viruses were present in the surveyed areas with different proportions of infection. Incidence was 69% of samples, with a peak of 80%, from the Alshifa and Fatima valleys, 60% from Rabigh and 55% from Khulais valley. FLMaV-1 was the prevailing virus (55% of samples, followed by FMV (34%, whereas FLMaV-2 (11% of samples and FMMaV (6% were less common. Most of the mosaic symptoms observed in surveyed fig orchards occurred with the presence of FMV. However, many other symptoms remained unexplained because of the arduous task of determining the involvement of other fig-infecting viruses with mosaic disease. This is the first report of FMMaV and FLMaV-2 in Saudi Arabia, and of FMV and FLMaV-1 in western Saudi Arabia. The virus status of this crop is probably compromised and a sanitation programme is required to produce healthy plant material in Saudi Arabia.

Energy consumption in KSA (kingdom of Saudi Arabia) is growing rapidly due to economic development with raised levels of population, urbanization and living standards. Fossil fuels are currently solely used to meet the energy requirements. The KSA government have planned to double its energy generating capacity (upto 120 GW (gigawatts)) by 2032. About half of the electricity capacity of this targeted energy will come from renewable resources such as nuclear, wind, solar, WTE (waste-to-energy) etc. Natural zeolites are found abundantly in KSA at Jabal Shamah occurrence near Jeddah city, whose characteristics have never been investigated in energy related applications. This research aims to study the physical and chemical characteristics of natural zeolite in KSA and to review its potential utilization in selected WTE technologies and solar energy. The standard zeolite group of alumina–silicate minerals were found with the presence of other elements such as Na, Mg and K etc. A highly crystalline structure and thermal stability of natural zeolites together with unique ion exchange, adsorption properties, high surface area and porosity make them suitable in energy applications such as WTE and solar energy as an additive or catalyst. A simple solid–gas absorption system for storing solar energy in natural zeolites will be a cheap alternative method for KSA. In AD (anaerobic digestion), the dual characteristics of natural zeolite like Mordenite will increase the CH_4 production of OFMSW (organic fraction of municipal solid waste). Further investigations are recommended to study the technical, economical, and environmental feasibility of natural zeolite utilization in WTE technologies in KSA. - Highlights: • A highly crystalline structure is found in natural zeolites. • Natural zeolites will store solar energy in solid–gas absorption system. • The composites of natural zeolites will produce more liquid fuel like gasoline. • The natural zeolite will increase

Full Text Available Objectives: Research activities in Saudi Arabia are promoted at the governmental and institutional levels. However, the output and quality of research conducted in the field of neurology has not yet been measured quantitatively. This study therefore aimed to analyse neurology-related publications from Saudi Arabia. Methods: This study was conducted in January 2016. A systematic search using the PubMed® search engine (National Library of Medicine, Bethesda, Maryland, USA was conducted to identify all neurology-related articles published from Saudi Arabia between January 1996 and December 2015. Results: A total of 1,292 neurologyrelated publications were identified. Neurology research increased linearly with time, with most publications originating from Riyadh (67% and the university sector (≈47%. However, most neurology-related articles were published in journals which had an impact factor of <1 (55%. Conclusion: Neurology research in Saudi Arabia has increased substantially over the last 20 years. However, as most articles were published in low-impact journals, the quality of research remains inadequate and should be improved. It is important that an official research culture be established in both governmental and private universities as well as colleges and health institutions in Saudi Arabia. The formation of clinical academic departments staffed by research experts is recommended to ensure the quality of neurology research output.

To describe the epidemiology and clinical features of stroke in a prospective and retrospective cohort of Saudi children and ascertain the causes, pathogenesis, and risk factors. The Retrospective Study Group (RSG) included children with stroke who were evaluated at the Division of Pediatric Neurology, or admitted to King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Kingdom of Saudi Arabia during the period July 1992 to February 2001. The Prospective Study Group (PSG) included those seen between February 2001 and March 2003. During the combined study periods of 10 years and 7 months, 117 children (61 males and 56 females, aged one month-12 years) were evaluated; the majority (89%) of these were Saudis. The calculated annual hospital frequency rate of stroke was 27.1/100,000 of the pediatric (1month-12 years) population The mean age at onset of the initial stroke in the 104 Saudi children was 27.1 months (SD=39.3 months) median and median was 6 months. Ischemic strokes accounted for the majority of cases (76%). Large-vessel infarcts (LVI, 51.9%) were more common than small-vessel lacunar lesions (SVLL, 19.2%). Five patients (4.8%) had combined LVI and SVLL. Intracranial hemorrhage was less common (18.2%), whereas sinovenous thrombosis was diagnosed in 6 (5.8%) patients. A major risk factor was identified in 94 of 104 (89.4%) Saudi children. Significantly more hematologic disorders and coagulopathies were identified in the PSG compared to the RSG (p=0.001), reflecting a better yield following introduction of more comprehensive hematologic and cogulation laboratory tests during the prospective study period. Hematologic disorders were the most common risk factor (46.2%); presumed perinatal ischemic cerebral injury was risk factor in 23 children (22.1) and infectious and inflammatory disorders of the circulatory system in 18 (17.3%). Congenital and genetic cerebrovascular anomalies were the underlying cause in 7 patients (6.7%) and

Objectives To investigate the prevalence of obesity among elementary school children and to examine the association between obesity and caries activity in the mixed dentition stage. Methods This cross-sectional study was conducted in King Abdulaziz University, Jeddah, Kingdom of Saudi Arabia between September 2014 and June 2015 using a multi-stage stratified sample of 915 elementary school children (482 boys, 433 girls) in Jeddah, Saudi Arabia. Anthropometric measurements, consisting of height, weight, body mass index (BMI), and waist circumference (WC), were obtained. Children were classified as underweight/healthy, overweight, or obese and as non-obese or obese according to their BMI and WC, respectively. Each child’s caries experience was assessed using the decay score in the primary and permanent teeth. Results Based on BMI, 18% of children were obese, 18% were overweight, and 64% were underweight/normal. Based on WC, 16% of children were obese, and 84% were non-obese. Girls had a significantly higher prevalence of obesity based on WC measurements (p<0.001), but not BMI. Children enrolled in private schools had a significantly higher prevalence of obesity (p<0.05) than those in public schools. For primary and permanent teeth combined, children with higher BMI and WC had a lower prevalence of caries (p<0.05). Conclusion The prevalence of obesity was high among male and female elementary school children. Overall caries activity was inversely proportional to BMI and WC. PMID:27874156

Saudi Arabia has had a unique experience in radiation monitoring of imported foodstuffs for possible contamination due to the Chernobyl reactor accident. A considerable amount of various food items is imported by Saudi Arabia and much of it comes from European countries. The quantity of imported food items is greatly increased around the time of the Moslem pilgrimage to Holy Mecca. Furthermore, many additional thousands of live animals (mainly sheep and cows) are imported for sacrificing on a certain day for religious reasons. The radiation monitoring of food items at inlets to the county was not done before and a lot of preparatory work and planning had to be done to initiate the monitoring process. The experience gained in this respect might be of value to other developing countries in a similar position. King Abdulaziz Univ. (KAU) was directed by the government in about mid-June 1986 to carry out radiological inspection of food items reaching the Jeddah, Yanbu, and Jizan seaports as well as food arrivals at King Abdulaziz International Airport at Jeddah. The KAU team has met with some difficulties in carrying out its inspection responsibilities. These difficulties are of a general nature and might occur, in a similar inspection process, in other developing countries. The problems can be classified essentially into the two categories discussed: (1) problems of an administrative and management nature, and (2) problems of a technical nature

Robins, Philip

2004-01-01

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

2016-01-01

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.

The power sector in the Kingdom of Saudi Arabia is undergoing the restructuring process. Moreover, during the last decade the Kingdom has witnessed a phenomenal growth in the load demand, consequently a huge amount of generation is added to the electric utilities to meet the load. Up to now only the electric utility generation was taken in the planning of the electrical sector. The data regarding the captive power generation was not readily available. A survey is conducted regarding the captive power generation in Saudi Arabia based on its utilization pattern, fuel used and amount of excess energy available to the grid. The existing regulatory framework and institutional structure of the Saudi power industry was also reviewed. Based on the information collected in the survey of captive power, key guidelines that may be considered in developing the policy for the captive power generators are presented. Furthermore, these guidelines and later the policies will help promote the investors to come forward in developing the captive power generation in Saudi Arabia. -- Highlights: •Database of captive power generation in the Kingdom of Saudi Arabia. •Historical perspective of electrical power industry in the Kingdom. •Saudi Arabia′s power requirements. •Regulatory framework and key guidelines regarding captive power generation. •It is first of its kind study in the region

2016-01-01

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

Saudi Arabia plans future strategy

International Nuclear Information System (INIS)

Roberts, John.

1996-01-01

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

The findings of the study showed that the questionnaires were collected from an equal portion of the study locale and that a sample of 741 is enough to create a strong conclusion and answer the problem set in this study and all the questions in the study have been provided with answers with enough data and literatures to supports its findings. Conclusion and Recommendations. The results indicate that an increase in the recruitment of Saudi males may simply reflect cultural issues such as gender specific facilities and the Saudisation program’s nondiscriminatory approach to employment of both genders into nursing.

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

Saudi Arabia is often presented in Western media as the poster child of women’s oppression. It is the country where women are forced to cover their heads and body in black dress and cannot drive cars. Although Saudi Arabia has ratified several human rights conventions, including the United Nations Convention on the Elimination of all Forms of Discrimination Against Women (CEDAW), there are many legal restrictions on Saudi women’s rights in the name of Sharia. Because Sharia, as applied by Sau...

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.

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

To assess the opinions of dental hygienists in Saudi Arabia regarding the establishment of a professional association including the role it should have to meet their professional needs. A cross-sectional electronic survey using Qualtrics was utilized. IRB exemption was obtained prior to distribution. Although there are 298 licensed Saudi dental hygienists in Saudi Arabia, email addresses were only available for 101 respondents: those obtained previously by direct contact for the purpose of initiation of a professional association and those referred by the direct contacts. Subjects were emailed a link to the survey. Seventy-seven subjects responded fully to the survey yielding a response rate of 70.3%. Most 91.5% (n = 65) of the respondents favoured the establishment of a Saudi dental hygiene professional association. Eighty-eight per cent (n = 59) responded that such an association would promote development of the profession in the country at least somewhat and 86.6% (n = 58) agreed that their professional needs could be met by its establishment. Interestingly, half of those who did not support the creation of the professional association believed it would promote development of the profession and meet professional needs. A representative sample of dental hygienists in Saudi Arabia support the establishment of a professional association and feel that it would advocate and promote the dental hygiene profession in the country and meet their professional needs. © 2018 John Wiley & Sons A/S.

Vitamin D deficiency is highly prevalent in Saudi Arabia. The study objective was to compare vitamin D deficiency in Saudi married couples. This cross-sectional study was carried out in the Royal Guard primary health care center in Riyadh, Saudi Arabia on a consecutive sample of 50 Saudi married couples attending the center without complaints related to vitamin D deficiency. Data were collected through an interview questionnaire addressing the risk factors and dietary habits. Quantitative determination of total 25-hydroxy vitamin D in blood was done by Electro-Chemical Luminescence assay. Fieldwork was carried out from December 2010 to January 2011. Men had higher sun exposure (P = 0.001), more use of light clothes at home (P = 0.002) and more intake of milk (P = 0.023) and soft drinks (P = 0.001). Vitamin D was higher in men with mean difference about 9 nmol/l (P activity and the intake of milk as statistically significant positive independent predictors of vitamin D level, adjusted for factors as age, sun exposure, clothing, skin color, BMI, soft drinks and animal protein intake. Vitamin D deficiency is very high among Saudi married couples, especially wives. Female gender is an independent predictor of lower vitamin D level, in addition to sedentary lifestyle and low milk consumption. There is a need to revise the levels set for the diagnosis of vitamin D deficiency or insufficiency in the study region.

Health literacy is a major problem worldwide and adversely affects an individual's health. The aim of the present study was to assess health literacy level among Saudi population. A cross-sectional study was conducted among a randomly selected population (n = 500) in Saudi Arabia. The questionnaire comprised of questions pertaining to demographic characteristics, health literacy and health information. Health literacy was measured by REALM-R test. Internal reliability was determined using Cronbach's alpha coefficient. The majority of the respondents had intermediate (43.8%) and basic (34.4%) health literacy levels. A higher percentage among men had intermediate (59.8%) and basic (70.93%) health literacy levels compared with women. About 30% of respondents had difficulty in understanding health screening tests and disease treatment. More than half of participants (52.4%) had difficulty in finding health information. The REALM-R test revealed that about 42.6% of individuals with score of >6 had adequate health literacy compared with 57.4% with score of ≤6 had inadequate health literacy. The present study demonstrated that a majority of Saudi individuals had inadequate health literacy that associated with poor knowledge of health information. Our findings highlighted the importance of understanding the status of health literacy among Saudis and the need for educational programs to raise the health literacy awareness among Saudi population. © The Author 2017.

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

Directory of Open Access Journals (Sweden)

Al-maghrabi, T.

2010-01-01

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

This study assessed the cultural competence of nursing students in a Saudi University. With the current situation of immigration in Saudi Arabia, the cultural diversity in healthcare facilities is anticipated to grow. This presents a great challenge to the members of the healthcare team. A cross-sectional study was conducted among 272 nursing students in a Saudi university using a self-administered questionnaire consisting of two parts, namely the respondents' demographics and cultural background information sheet and the Cultural Capacity Scale Arabic version. The respondents showed the highest competence in their ability to demonstrate communication skills with culturally diverse patients and lowest in the familiarity with health- or illness-related cultural knowledge or theory. Gender, academic level, clinical exposure, prior diversity training, the experience of taking care of culturally diverse patients and patients belonging to special population groups were significant factors that could likely to influence cultural competence. The findings suggest that the Saudi nursing students possess the ability to provide culturally appropriate nursing care to patients with a diverse cultural background. Despite the good cultural competence reflected in this study, some aspects in ensuring a culturally competent care rendered by Saudi nursing students need to be improved. With the country's Saudization policy in health care (replacing foreign nurses with Saudi nurses), the findings can be used in designing training and interventions to meet the needs of Saudi nursing students regarding cultural competence development, which is integral in their preparation to assume their future roles as nurses. Policy guidelines, such as including cultural competency training and foreign languages training as mandatory continuing education for nurses, as well as integrating cultural competency and foreign languages in the prelicensure curriculum, should be developed and implemented in

To report the prevalence of impacted third molars according to the age, gender and type among Saudi population. This retrospective study involved 3800 panoramic radiographs of subjects aged 18 to 45 years who presented to the College of Dentistry, King Khalid University, Abha, Kingdom of Saudi Arabia for oral care during the period from February 2009 to February 2011. Data collected was entered into a spreadsheet (Excel 2000; Microsoft, US) and analyzed using Statistical Package for Social Sciences (SPSS) version 16.0. A total of 713 impacted teeth were identified (18.76%) (p=0.003). The male to female ratio with impacted third molars was 604:109 (5.54:1) and the ratio of patients with impacted teeth was (5:1). Age group 1 (i.e., 20 to 25 years)had the highest prevalence of third molar tooth impaction (64.5%) and this decreased with increasing age. Incidence of tooth impaction is higher in the mandible than in maxilla. Males had a higher incidence of third molar impaction as compared to the females. Highest incidence is found in the age group of 20-25 years. Mesio-angular impaction was the most predominant type. How to cite this article: Syed KB, Kota Z, Ibrahim M, Bagi MA, Assiri MA.

Limited data exist on the epidemiology of cardiovascular risk factors in Saudi Arabia, particularly in relation to the differences between Saudi nationals and expatriates in Saudi Arabia. The aim of this analysis was to describe the current prevalence of cardiovascular risk factors among patients attending general practice clinics across Saudi Arabia. In this cross-sectional epidemiological analysis of the Africa Middle East Cardiovascular Epidemiological (ACE) study, the prevalence of cardiovascular risk factors (hypertension, diabetes, dyslipidemia, obesity, smoking, abdominal obesity) was evaluated in adults attending primary care clinics in Saudi Arabia. Group comparisons were made between patients of Saudi ethnicity (SA nationals) and patients who were not of Saudi ethnicity (expatriates). A total of 550 participants were enrolled from different clinics across Saudi Arabia [aged (mean ± standard deviation) 43 ± 11 years; 71% male]. Nearly half of the study cohort (49.8%) had more than three cardiovascular risk factors. Dyslipidemia was the most prevalent risk factor (68.6%). The prevalence of hypertension (47.5%) and dyslipidemia (75.5%) was higher among expatriates when compared with SA nationals (31.4% vs. 55.1%, p  = 0.0003 vs. p  Saudi Arabia. Improving primary care services to focus on risk factor control may ultimately decrease the incidence of coronary artery disease and improve overall quality of life. The ACE trial is registered under NCT01243138.

Communicating with cancer patients in Saudi Arabia.

Younge, D; Moreau, P; Ezzat, A; Gray, A

1997-02-20

The following factors are relevant to the communication problems that exist in this country: 1. The impression is that patients here cope better with terminal illness at home than do patients elsewhere. The extended family, with its strong ties, and the strong Islamic faith that encourages its members to provide for parents and children in case of need mean that any input by health professionals is magnified by the family in the care of the patient. At first, it was uncertain if foreign health professionals would be accepted into Saudi homes (which are intensely private and protected for the family) for the purpose of caring for patients. This has proved unfounded. Hospitality is a very important part of Saudi society; nurses and doctors are welcomed and respected. Much of this success is due to the use of Saudi men as drivers and translators. These people provide 24-hour service, act as social workers assessing the needs of the family, and are the link between the patient and family, the nurse, and the doctor. 2. "CURE" OR "PALLIATION": The emphasis for cancer patients in Saudi Arabia is still on "curative treatment," even after any realistic hope of a cure is gone. The problem this causes is compounded by many patients being excluded from the decision-making process. Decisions made by the family may not always reflect the patient's wishes. Greater communication is needed to guide treatment decisions. 3. TRUTH-TELLING: Denying information of the patient's illness is probably more a historical than a cultural phenomenon. Similar attitudes prevailed until very recently in practically all other countries. In this very conservative country, people are committed to preserving Islamic culture in the face of Western technology. As medicine continues to demonstrate its effectiveness as well as its limitations, people will come to realize that the right of patients to know and understand their illness allows them to cope much better, and is compatible with the

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

Intimate partner violence is a worldwide public health problem. The objectives of this study were to measure the prevalence and types of domestic violence, and to explore the association between social determinants (sociodemographic factors, husband-related factors, and social support) and violence against women by their intimate partner (husband). We conducted a cross-sectional survey in 18 randomly selected primary health care centers and 13 private institutions (teaching institutes, government offices, social welfare organizations) in Riyadh, Saudi Arabia. Female data collectors took interview from 1,883 married Saudi females aged 30 to 75 years. Interviews included sociodemographic information, reproductive health variables, and social support questionnaire. Violence was measured using modified Intimate Partner Violence Against Women questionnaire developed by the World Health Organization. Multivariate logistic regression analysis was conducted. The lifetime prevalence for any type of violence was 43.0% ( n = 810). The most frequent type was controlling behavior (36.8%), followed by emotional violence (22%), sexual violence (12.7%), and physical violence (9.0%). Multivariate logistic regression analysis revealed that the following were associated with greater odds of reporting domestic violence: younger age 30 to 40 years (adjusted odds ratio [aOR] = 1.9, 95% confidence interval [CI] = [1.3, 3.0]), 41 to 50 years (aOR = 1.6, 95% CI = [1.1, 2.5]); lack of emotional support (aOR = 1.7, 95% CI = [1.2, 2.5]); lack of tangible support (aOR = 1.4, 95% CI = [1.1, 1.9]); and perceived poor self-health (aOR = 1.7, 95% CI = [1.0, 3.0]), husbands' poor health (aOR = 1.9, 95% CI = [1.2, 2.0]), and polygamy (aOR = 1.6, 95% CI = [1.5, 2.6]). Domestic violence occurs frequently in Saudi Arabia. Both social conditions and social relations are significantly associated with domestic violence against Saudi women.

The aim of this study is to assess the clinical presentation of 23 patients with subacute thyroiditis (SAT) and the diagnostic value of radionuclear scan. This is a cohort study, which consists of 23 patients with a suspected diagnosis of subacute thyroiditis. The study was carried out in the Endocrinology Clinic, King Abdul-Aziz University Hospital, Jeddah, Kingdom of Saudi Arabia between July 2002 and July 2004. Medical charts including age, gender, clinical presentation, systemic symptoms and clinical examination of the thyroid gland were reviewed. Laboratory data included white blood count and its differential count, erythrocyte sedimentation rate (ESR), thyroid function test and thyroid antibodies. The radionuclear scan results were also noted. The mode of therapy provided to patients and the outcome of the treatment during a follow up period of 2 years was reported. Twenty-three adult patients with subacute thyroiditis (15 females and 8 males with a female to male ratio of 1.9:1) were reviewed over a 2-year period. The mean age was 35.8+9.2 years. Eighteen patients (78%) had an upper respiratory tract infection at the initial clinical presentation. Twenty patients (87%) visited an Ear, Nose and Throat specialist for sore throat and abnormal sensation in the throat at least 2 weeks before presentation to the endocrinologist. Two patients were admitted to a medical unit with a diagnosis of fever of unknown origin for 4 weeks. All patients had an elevated free thyroxine (35.7+19.8 pmol/L) and suppressed thyroid-stimulating hormone (TSH) (0.043+0.065IU). The radionuclear scan showed either no uptake at all in 12 patients or minimal uptake in 11 patients (0.32+0.55%). Eight patients (35%) received prednisolone therapy alone with an average dose of 30-40 mg daily for 7-8 days; 7 patients (30%) were treated with non-steroidal anti-inflammatory drugs (NSAIDs) only. Eight (35%) patients were treated with both NSAIDs and corticosteroids. Hypothyroidism, with elevated

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

Full Text Available Saudi Arabia has set itself the goal of developing a knowledge-based society. Demographic changes and economic growth within short time in the Kingdom of Saudi Arabia led to radical changes of the educational system. Higher education institutions are in expansion and international collaborations are being intensified. The policy of gender segregation based on a neopatriarchal society favored by the tribal system is an important cultural element of Saudi society and influences the Saudi educational culture.This article provides a scientific description and analyzes the main elements of the Saudi higher education system using the few data available due to the limited release of official statistics. Prince Mohammad Bin Fahd University is analyzed as a case study based on the author’s experience who taught there as an academic years of 2006 and 2008. Being the first private institution to admit both male and female students it had to face several challenges. Furthermore, the impact of international collaborations is identified by exploring the «King Abdullah Scholarship Programme» which gives thousands of students the opportunity to study abroad.Education while having a global function also fulfills a national function. Therefore, collaborations with Western universities in the Kingdom have created challenges for the recent generations in balancing Western values imposed throughout their higher education with their traditional culture. Due to the policy of gender segregation, the Saudi educational system represents different obstructions and opportunities particularly for female students.

Barriers and challenges in adopting Saudi telemedicine network: The perceptions of decision makers of healthcare facilities in Saudi Arabia

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

Western Saudi Arabia is surrounded by several active seismic zones such as the Red Sea and the Gulf of Aqaba where a destructive magnitude 7.3 event occurred in 1995. Over the last decade, the Saudi Geological Survey (SGS) has deployed a dense seismic network that has made it possible to monitor seismic activity more accurately. For example, the network has detected multiple seismic swarms beneath the volcanic fields in western Saudi Arabia. The most recent damaging event was a M5.7 earthquake that occurred in 2009 at Harrat Lunayyir. In terms of seismic hazard assessment, Zahran et al. (2015; 2016) presented a Probabilistic Seismic Hazard Assessment (PSHA) for western Saudi Arabia that was developed using published Ground Motion Prediction Equations (GMPEs) from areas outside of Saudi Arabia. In this study, we consider 41 earthquakes of M 3.0 - 5.4, recorded on 124 stations of the SGS network, to create a set of 442 peak ground acceleration (PGA) and peak ground velocity (PGV) records with a range of epicentral distances from 3 km to 400 km. We use the GMPE model BSSA14 (Boore et al., 2014) as a reference model to estimate our own best-fitting coefficients from a regression analysis using the events occurred in western Saudi Arabia. For epicentral distances less than 100 km, our best fitting model has different source scaling in comparison with the GMPE of BSSA14 adjusted for the California region. In addition, our model indicates that the peak amplitudes have less attenuation in western Saudi Arabia than in California.

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

Streptococcus pneumoniae (pneumococcus) is the leading cause of morbidity and mortality worldwide. Saudi Arabia is a host to millions of pilgrims who travel annually from all over the world for Umrah and the Hajj pilgrimages and are at risk of developing pneumococcal pneumonia or invasive pneumococcal disease (IPD). There is also the risk of transmission of S. pneumoniae including antibiotic resistant strains between pilgrims and their potential global spread upon their return. The country also has unique challenges posed by susceptible population to IPD due to people with hemoglobinopathies, younger age groups with chronic conditions, and growing problem of antibiotic resistance. Since the epidemiology of pneumococcal disease is constantly changing, with an increase in nonvaccine pneumococcal serotypes, vaccination policies on the effectiveness and usefulness of vaccines require regular revision. As part of the Saudi Thoracic Society (STS) commitment to promote the best practices in the field of respiratory diseases, we conducted a review of S. pneumoniae infections and the best evidence base available in the literature. The aim of the present study is to develop the STS pneumococcal vaccination guidelines for healthcare workers in Saudi Arabia. We recommend vaccination against pneumococcal infections for all children Saudi Arabia population <50 years of age, many of whom have risk factors for contracting pneumococcal infections. A section for pneumococcal vaccination before the Umrah and Hajj pilgrimages is included as well. PMID:27168856

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

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

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

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

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

2015-11-01

Full Text Available Alpha-thalassemia (α-thal is a disorder caused by the deletion of single or double α-globin genes, and/or point mutations in the α-globin genes. There are 2 common types of α-globin genes; HBA2 and HBA1. Recently, it has been discovered that the HBA2 gene is replaced by a unique HBA12 gene convert in 5.7% of the Saudi population. The α-globin genes have been emerging as a molecular target for the treatment of β-thalassemia (β-thal. Hence, it is essential to understand the molecular nature of α-globin genes to treat the most prevalent hemoglobin disorders, such as sickle cell disease, α-thal, and β-thal prevalent in the Kingdom of Saudi Arabia. Thirty-two different α-globin genotypes have been observed in the Saudi population. This review outlines the classification of the α-globin genes on the basis of their molecular nature and complex combinations of α-globin genes, and their variants predominant in Saudis.

Patients' satisfaction of service quality in Saudi hospitals: a SERVQUAL analysis.

Al-Borie, Hussein M; Damanhouri, Amal M Sheikh

2013-01-01

Saudi Arabian hospital performance, vis-á-vis patient satisfaction with service provision, has emerged as a key policy and planning concern. Keeping in view public and private hospital service quality, this article seeks to provide guidelines to the on-going Saudi Arabian health service reorganization, which emphasizes decentralization, bed-capacity expansion, research-based policymaking and initiatives in the health insurance sector. The article outlines an empirical study that compares patient satisfaction with service quality in Saudi Arabian public and private sector hospitals. The authors employ a stratified random sample (1,000 inpatients) from five Saudi Arabian public and five private hospitals. Data were collected through questionnaire using the SERVQUAL scale. For reducing the language bias the questionnaire was translated into Arabic. The response rate was 74.9 percent. Data were analyzed using SPSS and appropriate descriptive and inferential statistical techniques. Cronbach's alpha for five service-quality dimensions (tangibles, reliability, responsiveness, safety and empathy) were high and the SERVQUAL instrument proved to be reliable, valid and appropriate. The results showed that sex, education, income and occupation were statistically significant in influencing inpatients' satisfaction, and all the null hypotheses were rejected. Only inpatient age was not significant. The study highlights service quality influence in the design of broader healthcare strategies for Saudi Arabian public and private hospitals. It demands that management researchers and analysts must identify regional service quality consistencies and related inpatient demographic indicators. The study offers some insights into, and guidance for, hospital quality assurance in Saudi Arabia in general and the urban hospital setting in the Middle-East in particular.

Hajj is the world's largest annual mass gathering that attracts two to three million Muslims from around the globe to a religious assemblage in Makkah, Saudi Arabia. The risk of acquisition and transmission of influenza among Hajj pilgrims is high. Therefore, influenza vaccination is recommended, and was monitored frequently among pilgrims from different countries. However, the vaccination uptake among Saudi pilgrims has not been assessed in recent years. This analysis aims to evaluate influenza vaccine uptake among Saudi Hajj pilgrims, and identify the key barriers to vaccination. Data on influenza vaccination were obtained from Saudi pilgrims who took part in a large trial during the Hajj of 2013, 2014 and 2015. Pilgrims were met and recruited in Mina, Makkah during the peak period of Hajj and were asked to complete a baseline questionnaire that recorded their influenza vaccination history, including reason(s) for non-receipt of vaccine. A total of 6974 Saudi pilgrims aged between 18 and 95 (median 34) years were recruited; male to female ratio was 1:1.2. Of the total, 90.8% declared their influenza vaccination history, 51.3% of them reported receiving influenza vaccine before travel to Hajj. The vaccination rates for the years 2013, 2014 and 2015 were 21.4%, 48.2% and 58.1%, respectively (P Saudi Hajj pilgrims is increasing over years but still needs further improvement. Lack of awareness and misperceptions are the main barriers. Education of Saudi pilgrims and health professionals is required to raise awareness about influenza vaccination. Further studies are needed to understand pilgrims' misperceptions. Copyright © 2018 Elsevier Ltd. All rights reserved.

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

Decadal variation of wet-season precipitation has been found in the arid region of central Saudi Arabia. 1980s has been a rather wet decade compared with the decades before. Previous studies have mentioned that the irrigation moisture may contribute to the precipitation anomalies in Saudi Arabia. In the current study, we show from observational data that the contribution of the variation comes mostly from February to May. As the irrigation is a localized forcing, we therefore use the Weather Research and Forecasting (WRF) Model to simulate the response of the land-atmosphere interaction to the wet soil moisture resulted from additional irrigation moisture supply. Preliminary result shows in the irrigated simulation that precipitation in central Saudi Arabia is enhanced, indicating the possible link between irrigation expansion in the 1980s and the decadal precipitation variation over central Saudi Arabia. We propose it is the anomalous convergence induced by irrigation as well as additional moisture that contribute to the enhanced precipitation over heavily irrigation region in the central Saudi Arabian. In addition, analysis on the daily precipitation from the WRF outputs indicates that positive rainfall anomalies tend to happen when there is rainfall originally; that is, irrigation enhances rainfall but not creates rainfall.

Full Text Available The main purpose of the study is to analyze the contribution of Saudi woman in economic development of the country. This report develops an understanding of women contributions towards economic development. The method used to analyze the data was Pearson correlation. Through correlation we can determine the relationship between the variables. The study was a quantitative study. The data for five years was taken. Hypotheses development proceeded by focusing on labor work force participation, literacy rate of adult females and GDP rate within Saudi Arabia. Analysis was done on the results and the findings confirmed that there is a significant relationship between the variables. This study was of exploratory nature, it is recommended that this research be expanded to a statistically valid base within Saudi Arabia and then expand the study to additional countries. The findings showed that there was a high significant relationship between women labor work force participation and GDP. Whereas, there was moderate significant relationship between labor work force and literacy rate. Hence, there is a positive relationship between women contribution and economic development. The research is conducted within the context of Saudi Arabia and has certain limitation with further directions of conducting research in related field to get more accurate results.

Saudi demographic composition has changed because of increased life expectancy and decreased fertility rates. Little data are available about health conditions among older adults in Saudi Arabia, who are expected to represent 20% of the population by 2050. The study aim was to assess the prevalence and risk factors for chronic conditions among older Saudi men. The sample pertained to 400 men (age ≥55 years) from Buraidah, Al-Qassim. Research assistants recruited participants in all the mosques from the randomly selected neighborhoods (16 of 95). They administered a structured questionnaire that assessed self-reported disease history (heart disease, hypertension, diabetes, asthma, gastric/peptic ulcer, and cancer), and medication use; participants' height, weight, blood pressure, and random blood glucose (glucometer) were measured. Multinomial logistic regressions were employed to assess correlates of number of chronic diseases. The mean and standard deviation for age and body mass index (BMI) were 63.0 ± 7.5 years and 28.9 ± 4.8 (kg/m 2 ), respectively. 78% (77.8%) were overweight or obese, 35.0% were employed, 54.5% walked daily, 9.3% were current smokers, and 85.0% belonged to the middle class. The prevalence of hypertension, diabetes, heart disease, asthma, ulcer, and cancer were: 71.3% 27.3%, 16.4%, 9.7%, 8.9%, and 2.0%, respectively. Of the participants, 31.0% had one, 34.5% had two or more, and 34.5% did not have any chronic diseases. The likelihood of chronic diseases increased with increased age, higher BMI, and current smoking. The chronic disease prevalence among the Saudi elderly men is substantial.

The distribution of hepatitis C virus (HCV) genotypes in the Western Province of Saudi Arabia is unknown. The purpose of our study was to determine the prevalent HCV genotypes among HCV seropositive Saudi patients in the Western Province and to study the relationship between types/subtypes, clinical status and liver histology. Serum samples were collected from 140 consecutive patients attending the Hematology Clinic with varying grades of liver diseases, high almandine transferees (ALT) for > 6 months, positive HCV, qualitative PCR and who had liver biopsy. HCV genotyping was determined on patients who had tested positive by both HCV enzyme immunoassay (EIA) and the recombinant immunoblot assay (RIBA). Of the 140 patients, 97 (69.2%) had genotype 4, 18 (12.8%) had genotype 1a, and 16 (11.4%) had genotype 1b. Genotype 2b and 5 were found in two patients (1.4%) each, while 5 patients (3.6%) had mixed infections with genotype 4 and 5. Of the 97 patients infected with genotype 4, 84 (86.6%) had chronic active hepatitis (CAH), two (2.1%) had CAH with active cirrhosis, 9(9.3%) had cirrhosis and two (2.1%) had normal liver histology (NLH). The most prevalent HCV genotype in the Western Province of Saudi Arabia was genotype 4 (69.2%). Genotype 1b was encountered in 16 (11.4%) patients. For the first time, genotype 5 was identified in the Western Province of Saudi Arabia. Genotype 1b and 4 were associated with different histological grades of liver disease. (author)

Rehman, Shafiqur

2004-01-01

The paper presents long term wind data analysis in terms of annual, seasonal and diurnal variations at Yanbo, which is located on the west coast of Saudi Arabia. The wind speed and wind direction hourly data for a period of 14 years between 1970 and 1983 is used in the analysis. The analysis showed that the seasonal and diurnal pattern of wind speed matches the electricity load pattern of the location. Higher winds of the order of 5.0 m/s and more were observed during the summer months of the year and noon hours (09:00 to 16:00 h) of the day. The wind duration availability is discussed as the percent of hours during which the wind remained in certain wind speed intervals or bins. Wind energy calculations were performed using wind machines of sizes 150, 250, 600, 800, 1000, 1300, 1500, 2300 and 2500 kW rated power. Wind speed is found to remain above 3.5 m/s for 69% of the time during the year at 40, 50, 60, and 80 m above ground level. The energy production analysis showed higher production from wind machines of smaller sizes than the bigger ones for a wind farm of 30 MW installed capacity. Similarly, higher capacity factors were obtained for smaller wind machines compared to larger ones

Almutairi, Adel F; McCarthy, Alexandra; Gardner, Glenn E

2015-01-01

In Saudi Arabia, the health system is mainly staffed by expatriate nurses from different cultural and linguistic backgrounds. Given the potential risks this situation poses for patient care, it is important to understand how cultural diversity can be effectively managed in this multicultural environment. The purpose of this study was to explore notions of cultural competence with non-Saudi Arabian nurses working in a major hospital in Saudi Arabia. Face-to-face, audio-recorded, semistructured interviews were conducted with 24 non-Saudi Arabian nurses. Deductive data collection and analysis were undertaken drawing on Campinha-Bacote's cultural competence model. The data that could not be explained by this model were coded and analyzed inductively. Nurses within this culturally diverse environment struggled with the notion of cultural competence in terms of each other's cultural expectations and those of the dominant Saudi culture. The study also addressed the limitations of Campinha-Bacote's model, which did not account for all of the nurses' experiences. Subsequent inductive analysis yielded important themes that more fully explained the nurses' experiences in this environment. The findings can inform policy, professional education, and practice in the multicultural Saudi setting. © The Author(s) 2014.

Objective was to report on the prognosis, neurologic outcome, and recurrence of stroke in Saudi children. We evaluated a cohort of 104 Saudi children with stroke at the Division of Pediatric Neurology at King Khalid University Hospital, College of Medicine, King Saud University, Riyadh, Saudi Arabia from July 1992 to February 2001 (retrospective study) and February2001 to March 2003 (prospective study). We analyzed the salient clinical, neuroimaging, neurophysiological, neuropsychological and laboratory data following retrieval from a specially designed comprehensive protocol. Of the 104 children in the cohort (aged one month to 12 years), 5 (4.8%) died during the study period and 9(8.7%) were lost to follow-up. The mean duration of follow-up for the remaining 90 children was 40 months (median 33 months). Recovery was judged complete in 6(6.7%) of these 90 children. We detected residual hemiparesis (irrespective of its effect on daily functions) in 73 (81%) and this was combined with other motor deficits in 45 children (50%). Forty-one children (46%) had residual dysphasia or language deficits, whereas 45 (50%) were judged to have had cognitive deficit. Psychometry revealed an abnormal intelligence quotient test (70) in 19 of 26 (73%) children. Other neurologic sequelae included epilepsy in 52 (58%), recurrent headaches in 13 (14%) and hydrocephalus in 4 (4.4%) patients, Six of the 95 (6.3%) children, who were ascertained to have died or kept their follow-up, had one or more occurrences, one month to 5 years after initial stroke (median 23 months). Patients who had recurrent strokes were significantly more likely to be the product of consanguineous marriages (p=0.04). Regarding the group of 23 children with perinatal stroke, neither deaths nor recurrences occurred during the follow-up period. However, 20 (87%) of them had significant delays in their developmental milestones. The toll of stroke in Saudi children is demanding, with most children demonstrating

The expressions of dissent in contemporary Saudi Arabia, whether through violent action or ideological and theological constructions, are well documented today. The very contexts within which violence appears and develops are less well known. If it is essential to read and analyse the Islamic discourses and to observe and interpret the history of Islamic activism in Saudi Arabia, such an elitist focus may overlook more discrete events that might explain the way ordinary people refer to state ...

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

2015-01-01

Evidence-based medicine has established itself in the field of gastroenterology. In this study we aim to assess the types of study designs of gastroenterology-related articles published in Saudi scientific journals. An online review using PubMed was carried out to review gastroenterology-related articles published in six Saudi medical journals in the time interval from 2003 to 2012. To classify the level of evidence in these articles we employed the Oxford's levels of evidence. One-way analysis of variance was used to compare the levels of evidence between published articles. A total of 721 gastroenterology-related articles were reviewed, of which 591 articles met our inclusion criteria; 80.7% were level IV. The three most common types of studies we encountered were cross-sectional (33.9%), case reports (27.9%), and case series (18.8%). Forty-three percent of the published research was in the field of hepatobiliary and spleen. The total number of articles increased from 260 articles in the 1 st 5-year period (2003-2007) to 330 in the 2 nd period (2008-2012). However, no statistically significant difference in the level of evidence was noted. In Annals of Saudi Medicine Journal, articles with level II increased from 0 to 10% with a P value 0.02. In our review of gastroenterology-related published articles in Saudi scientific journals, we observed an increase in the quantity of articles with the quality and level of evidence remaining unchanged. Further research is recommended to explore different reasons affecting the volume and quality of gastroenterology-related research in Saudi scientific journals.

To estimate the lifetime prevalence and address the attitudes and knowledge of using prohibited substances (doping) among sport players in Saudi Arabia. A cross-sectional survey carried out using systematic random sampling technique among Saudi players of variable sports attending the sport clubs, stadiums, and sport fields (70 sport clubs, 22 types of sports belong to 22 Saudi sport federations were visted in 18 cities from all regions of Saudi Arabia). A total of 1142 male sport players were interviewed with main age of 24. The prevalence of using prohibited substances (doping) was 4.3 %. The main reason for using prohibited substances was to improve performance (69 %). The prevalence of using food supplements (not prohibited) was 38.4 %. Among the players, 30 % of them believe that such behavior is against the spirit of sport while 70 % of the players are aware of punishment against doping. 65 % of players admitted that they received advice on prohibited substances. Higher rate of using prohibited substances (doping) among Saudi players was associated with low education, age below 20 years, previous use of food supplements and lack of punishment awareness. Using prohibited substances (doping) among Saudi sport players is common. Players believe that such use is against the spirit of the sport and they are aware about its punishment, despite this, they are still using prohibited substances.

Stress is a perennial problem in nursing education and Saudi student nurses are not immune. Despite the growing literature examining stress in Saudi student nurses, a broader perspective on this concept has not been explored. This paper is a report of a review systematically appraising and synthesizing existing scientific articles reporting stress perceptions and coping styles in Saudi student nurses. A systematic review method guided this review. Four (SCOPUS, CINAHL, PubMed, Ovid) bibliographic databases were searched to locate relevant articles. An electronic database search was performed in August 2017 to locate studies published from 2010 onwards. The search words included: "stress" OR "psychological stress", "coping" OR "psychological adaptation", "Saudi Arabia", "student", and "nurse". Eleven (11) articles met the inclusion criteria. Review of the findings showed moderate to high stress levels in Saudi student nurses that originated mainly from heavy workloads and taking care of patients. However, when the students' demographic characteristics were taken into account, inconclusive results were found, although some evidence showed higher stress levels in higher level students. Both active and passive coping styles were used by nursing students when dealing with stress. Consistent with international studies, Saudi student nurses experience a considerable levels of stress from various sources. Findings may provide a direction for nursing faculty in formulating stress interventions that are empirically tested and culturally appropriate. Copyright © 2018 Elsevier Ltd. All rights reserved.

Apology Strategies Employed by Saudi EFL Teachers

Directory of Open Access Journals (Sweden)

Marzouq Nasser Alsulayyi

2016-12-01

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

2012-01-01

If evaluation of economic evidence is to be used increasingly in Saudi Arabia, a review of the published literature would be useful to inform policy decision-makers of the current state of research and plan future research agendas. The purpose of this paper is to provide a critical review of the state of health economic evaluation research within the Saudi context with regard to the number, characteristics, and quality of published articles. A literature search was conducted on May 8, 2011 to identify health economic articles pertaining to Saudi Arabia in the PubMed, Embase, and EconLit databases, using the following terms alone or in combination: "cost*", "economics", "health economics", "cost-effectiveness", "cost-benefit", "cost minimization", "cost utility analysis", and "Saudi". Reference lists of the articles identified were also searched for further articles. The tables of contents of the Saudi Pharmaceutical Journal and the Saudi Medical Journal were reviewed for the previous 5 years. The search identified 535 citations. Based on a reading of abstracts and titles, 477 papers were excluded. Upon reviewing the full text of the remaining 58 papers, 43 were excluded. Fifteen papers were included. Ten were categorized as full economic evaluations and five as partial economic evaluations. These articles were published between 1997 and 2010. The majority of the studies identified did not clearly state the perspective of their evaluation. There are many concerns about the methods used to collect outcome and costs data. Only one study used some sort of sensitivity analysis to assess the effects of uncertainty on the robustness of its conclusions. This review highlights major flaws in the design, analysis, and reporting of the identified economic analyses. Such deficiencies mean that the local economic evidence available to decision-makers is not very useful. Thus, building research capability in health economics is warranted.

Gastroesophageal reflux disease (GERD) is a common chronic gastrointestinal tract disease. The incidence is higher in Asian and Arab countries. In Saudi Arabia, there are few studies that have assessed the prevalence of GERD among some cities' communities. Hence, this study aims to study the prevalence of GERD among the general population of Saudi Arabia. A cross-sectional study was designed to determine the prevalence of GERD among the community of Saudi Arabia. The sample was randomly gathered through self-administered validated GERD questionnaire (GerdQ) to diagnose GERD, during the period from November to December 2016. The sociodemographic data was assessed for all participants. The data were analysed using Statistical Package for Social Sciences version 21.0 (SPSS); the t -test was used to assess the association of GERD and sociodemographic data. The sample was comprised of 2,043 participants. Female and male were 51.8% and 48.2%, respectively. Mean age was 29.6 years with the standard deviation of 10.5 years. The GERD prevalence was 28.7%. It was found statistically significant among divorced/widow (34.9%, P = 0.003). In contrast, there was no association between GERD's prevalence and gender, age, residence status, education level, occupation, and blood group (P > 0.05). The prevalence of GERD among Saudi population is higher than that in Western countries and East Asia. It affects divorced/widow, obese and those with a sedentary lifestyle. It is advocated that national programs and educational campaigns for prevention of this disease and its complications should be established.

Efforts of Controlling Money Laundering of Narcotics Money in Saudi Arabia

Khaled A. ALASMARI

2014-06-01

Full Text Available Money laundering is a silent crime. Its goal is to cover up the source of large sums of money that criminals often gather from their criminal activities. This paper will analyze the situation of money laundering in narcotics as it applies in Saudi Arabia. To achieve this end, the paper will first define important terms such as money laundering and narcotics. It will then explain the relationship between money laundering, narcotics trade, and terrorism activities. This background information will form the base for analyzing the various efforts that the Saudi Arabia nation has in place for countering money laundering in narcotics trade. The paper will then explain the challenges facing these efforts, and the future of money laundering in Saudi Arabia. The largest criminal activity associated with money laundering is terrorism financing. The several terror attacks associated with Saudi Arabia’s terror groups like Al-Qaida have made the government realize the importance of curbing money laundering in an effort to counter terrorism. Thus, anti-money laundering strategies are set in place to address all the avenues of money laundering.

Saudi Arabian Green Economy Infrastructure: Barriers, Strategies & Opportunity – An Analysis

Nisreen Ismail Albanawi

2015-11-01

Full Text Available Saudi Arabia is finally catching up with the rest of the developed world in terms of environmental awareness. In the past, while much of the rest of the world spent its time pondering issues such as global warming, water, air, and soil pollution, over-exploitation of resources, and a myriad of other environmental concerns, the Saudi people and government seemed to be primarily focused on expanding their capital in a globalized economy. However, in 2015, for the first time, this trend began to show legitimate change. This new emphasis on environmental concerns has caused some interest and uproar, specifically in the economic sector. The research, therefore, concentrated on the barriers, strategies, and opportunities that might impede or encourage Saudi Arabia in its quest to develop a greener and more sustainable economic infrastructure. After carefully considering the available literature, data, and reliable statistics, the report concluded that, while change will be difficult and, possibly slow, Saudi Arabia should expect to see greener projects and initiatives transpiring in their homeland over the course of the next several years.

To evaluate and compare the perceptions of Saudi dentists and lay people to altered smile features. Thirty-six digital smile photographs with altered features were used. Altered features included the following: crown length, width, gingival level of the lateral incisors, gingival display, midline diastema, and upper midline shift. The photographs were presented to a sample of 30 dentists and 30 lay people with equal gender distribution. Each participant rated each picture with a visual analogue scale, which ranged from 0 (very unattractive) to 100 (very attractive). Dentists were more critical than lay people when evaluating symmetrical crown length discrepancies. Compared to lay people, Saudi dentists gave lower ratings to a crown length discrepancy of >2 mm (P 1 mm (P lay people towards alterations in the gingival level of the lateral incisors or towards a space between the central incisors. No significant sex difference was seen across the groups. In this sample, Saudi dentists gave significantly lower attractiveness scores to crown length and crown width discrepancies, midline deviations, and changes in gingiva to lip distance compared to Saudi lay people.

The Kingdom of Saudi Arabia has shown steady growth in the dental workforce over the last 20 years. Although the number of dental colleges has significantly increased in the last decade, there is not any study so far that described the status of the licensed dentist workforce in the kingdom. The present study aimed to explore the demographic distribution and professional characteristics of licensed dentist workforce in Saudi Arabia. This was a descriptive cross-sectional study using the Saudi Commission for Health Specialties (SCFHS) database to identify the number of licensed dentists in Saudi Arabia as well as their professional and demographic characteristics as of December 2016. The data was categorized based on gender, nationality, dental specialty, health sector, geographic location, and professional rank. The number of licensed dentists working in the kingdom as of December 2016 was 16887 dentists, and the vast majority of them are professionally registered as general dentists (70.27%). The percentage of general dentists among the professionally registered female dentists is significantly higher than their male counterparts (79.71% vs. 64.80%; P  sector in comparison to only 20.46% of the non-Saudi dentists ( P  sectors. With the rising unemployment rate among Saudi dentists, the governmental bodies that are responsible of dental labor market regulations such as the ministries of health, economy and planning, and labor should come up with a policy to gradually but carefully replace the non-Saudi dentists in both public and private sectors with Saudi dentists.

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

Inherited color vision deficiencies (CVD) vary in prevalence by population and by sex. The most common CVD is X chromosome-linked anomalous trichromacy. Prevalence varies significantly by sex and race. The frequency of color vision defects in Saudi females has not been studied previously. This study surveyed the prevalence of congenital color vision defects in Saudi females of Arab origin. Seven thousand four hundred sixty-seven female subjects (N = 7,467) from the Kingdom of Saudi Arabia were screened using both Ishihara pseudoisochromatic plates and the Farnsworth Dichotomous test (D-15). CVD subjects were tested further with the Farnsworth-Munsell 100 Hue test. Of 7,467 female subjects tested, 26 subjects were found to have defective color vision, for a prevalence of 0.35%. Sixteen subjects had a deutan defect, and 10 had a protan defect. Arab females have significantly lower prevalence of CVD when compared with published data from females of other races. Analysis of the 5 regions of Saudi Arabia showed no significant difference between the regions. Prevalence of CVD among Saudi females of Arab origin is 0.35% and is among the lowest of all published data. Copyright © 2011 American Optometric Association. Published by Elsevier Inc.

This study aimed to examine perceived stress and its risk factors and consequences among consultant physicians in Saudi Arabia. Methods: A cross-sectional study was conducted from November 2014 to March 2015 among physicians who were assigned rank of consultant. The stress level was assessed using perceived stress scale (PSS.Results: A total of 582 consultants participated. The average age was 46.9±7.9 years, 71% were males, 56% were Saudi, 15% were smokers, and 68% slept ≤6 hours per night. The median PSS score was 17 (interquartile range of 14–21, which represented 44% of maximum possible PSS score. The upper tertile of PSS score (represents a high stress level was significantly associated with being younger, female, and Saudi. The majority (85% considered job environment to be stressful and ~50% attributed that to a high workload and a noncooperative administration. In the year preceding this study, half of consultants frequently contemplated or even worked toward changing their medical institutes or even moving to work outside Saudi Arabia because of perception of a stressful working environment. Over the previous year, encountering life stressors, considering job environment as stressful and experiencing passive suicidal ideation, were significantly associated with higher levels of stress

Rabies in Saudi Arabia: a need for epidemiological data

Directory of Open Access Journals (Sweden)

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

The Ulama and the Al Saud: A Relationship Between Elites in Saudi Arabia

OpenAIRE

Permuy, Alexandra

2016-01-01

The origins of the Kingdom of Saudi Arabia date back to the alliance forged between the AlSaud and the preacher Muhammad Ibn AbdulWahhab in the 18th century, and the subsequent establishment of the first Saudi state. Since then, the religious scholars, or ulama, have played an important role that is still vital to the continued survival of the Saudi regime’s credentials. However, that role has changed overtime. Historically, the AlSaud and the ulama were elites of equal standing, but oil reso...

Analysis of Saudi Arabia's behavior within OPEC and the world oil market

We analyze oil export behavior by Saudi Arabia and the Rest of OPEC since 1973. In the literature there has been a wide range of estimates of their correlation: from positive, to zero, to negative. We find that the correlation has varied over time, from moderately high (0.7) in normal periods, to negative during each of five interruptions; the average correlation has been 0.19. Saudi Arabia's oil market behavior depends upon circumstances, but its primary goal is the stability of OPEC and the world oil market. It will coordinate export reductions with the Rest of OPEC when faced with declining demand, but it will increase exports when faced with interruptions elsewhere in OPEC. Allowing for such differences provides evidence of intelligent, context-dependent consistency. But ignoring context – by wrongly assuming the same Saudi response in Normal periods and Interruptions – can lead to a conclusion of Saudi “inconsistency” because the difference in the responses has been obscured

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

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

Too costly to matter: Economics of nuclear power for Saudi Arabia

International Nuclear Information System (INIS)

2014-01-01

Saudi Arabia has ambitious plans for nuclear power. Given this context, this paper examines the economics of nuclear power and compares it to two other sources of electricity, natural gas and solar energy. It calculates the costs of electricity generation, water desalination and the opportunity cost associated with forgone oil and gas revenues. A sensitivity analysis is included to account for variations in important parameters within the comparative cost analysis. Our results suggest that for a large range of parameters, the economics of nuclear power are not favorable in comparison with natural gas, even if the currently low domestic natural gas prices in Saudi Arabia were to rise substantially. Further, electricity from solar plants has the potential to be cheaper than nuclear power within the next decade if the rapid decline in solar energy costs in the last decade continue, i.e., before the first planned nuclear power plant would be completed. However, unless the price of oil drops substantially below current values, it would be more economically optimal to export the oil than using it for generating electricity. - Highlights: • Future projections show nuclear power is not cost effective for Saudi Arabia. • A combination of solar and natural gas could largely meet future electricity demand. • There are multiple, non-economic, motivations for Saudi Arabia's nuclear program. • Saudi Arabia would economically benefit by not using oil for electricity generation
