    This study illustrates about the most hazardous and risky activities associated with well drilling operation at on and offshore
    oil and gas drilling sites by adopting exploratory research design (quantitative leading to qualitative). In this study researcher has
    targeted three oil and gas industries each from Malaysia, Saudi Arabia and Pakistan for the identification of associated hazards
    and nature of hazardous activities faced by drilling crew during well drilling operation. Eighty (80) drilling crew members have
    been randomly selected for answering the survey questionnaire. Likewise, nine (09) drilling health and safety officials have been
    conveniently selected based on their safety expertise in oil and gas drilling field for semi structured in-depth interview. For analyzing
    quantitative findings descriptive statistical methods has been used. While for qualitative section thematic analysis approach has
    been utilized. Based on the findings, respondents from Malaysian oil and gas industries reported starting drilling activity as highly
    hazardous at onshore well drilling, while handling drilling pipe has been considered more hazardous activity at offshore domain.
    Similarly, in the context of Saudi Arabia, respondents highlighted that the handling drilling pipes are cause of major injuries at onshore
    well drilling site. Whereas drilling fluid preparation and coring process is considered harmful at offshore sites. In contrast, participant
    from Pakistan indicated coring process as a highly hazardous activity at on and offshore well drilling operation. According to overall
    results based on the participant response, oil and gas well drilling operation at onshore domain is considered more hazardous
    at Pakistani oil and gas industry as compare to other targeted industries with mean range 3.42. While for offshore well drilling,
    Malaysian industry is recorded highly hazardous as compare to others leading with mean value 3.39 and related with chemical and
    safety hazards in well drilling activities.

    Patient effective doses and the associated radiation risks arising from particular computed tomography (CT) imaging procedures are assessed. The objectives of this research are to measure radiation doses for patients and to quantify the radiogenic risks from CT brain and chest procedures. Patient data were collected from five calibrated CT modality machines in Saudi Arabia. The results are from a study of a total of 60 patients examined during CT procedures using the calibrated CT units. For CT brain and chest, the mean patient effective doses were 1.9 mSv (with a range of 0.6-2.5 mSv) and 7.4 mSv (with a range of 0.5-34.8 mSv) respectively. The radiogenic risk to patients ranged from between 10-5 and 10-4 per procedure. With 65% of the CT procedure cases diagnosed as normal, this prompts re-evaluation of the referral criteria. The establishment of diagnostic reference levels (DRL) and implementation of radiation dose optimisation measures would further help reduce doses to optimal values.

    This study was conducted to retrieve the land surface temperature (LST) from Landsat ETM+ data for Al Qassim, Saudi Arabia. The proposed technique employed a mono window LST algorithm for retrieving surface temperature from Landsat ETM+. The land surface emissivity and solar angle values were needed in order to apply these in the proposed algorithm. The surface emissivity values were computed based on the NDVI values. The LST values derived from ATCOR2_T in the PCI Geomatica image processing software was used for algorithm calibration. The results showed a high correlation
    coefficient (R) and low root-mean-square error (RMS) between the LST values retrieved from the proposed algorithm and ATCOR2_T. This study indicated that the proposed algorithm is capable of retrieving accurate LST values and the derived information can be used in the environmental impact assessment for Al Qassim area.

    Saline tolerant mangrove forests partake in vital biogeochemical cycles. However, they are endangered due to deforestation as a result of urbanization. In this study, we have carried out a metagenomic snapshot of the mangrove ecosystem from five countries to assess its taxonomic, functional and antibiotic resistome structure. Chao1 alpha diversity varied significantly (P Saudi Arabia, China, India and Malaysia). All datasets were composed of 33 phyla dominated by eight major phyla covering >90% relative abundance. Comparative analysis of mangrove with terrestrial and marine ecosystems revealed the strongest heterogeneity in the mangrove microbial community. We also observed that the mangrove community shared similarities to both the terrestrial and marine microbiome, forming a link between the two contrasting ecosystems. The antibiotic resistant genes (ARG) resistome was comprised of nineteen level 3 classifications dominated by multidrug resistance efflux pumps (46.7 ± 4.3%) and BlaR1 family regulatory sensor-transducer disambiguation (25.2 ± 4.8%). ARG relative abundance was significantly higher in Asian countries and in human intervention datasets at a global scale. Our study shows that the mangrove microbial community and its antibiotic resistance are affected by geography as well as human intervention and are unique to the mangrove ecosystem. Understanding changes in the mangrove microbiome and its ARG is significant for sustainable development and public health.

    BACKGROUND: Respiratory tract infections are one of the common infection associated with Hajj pilgrimage that is of great public health and global concern. This study is aimed at determining the factor structure of the knowledge, attitude, and practice questionnaire for the prevention of respiratory tract infections during Hajj by confirmatory factor analysis (CFA).

    METHODS: A multistage cluster sampling method was conducted on Malaysian Umrah pilgrims during the weekly Umrah orientation course. A total of 200 Umrah pilgrims participated in the study. The knowledge, attitude and practice (KAP) questionnaire was distributed to pilgrims at the beginning of the orientation and retrieved immediately at the end of the orientation. Data analysis was done using R version 3.5.0 after data entry into SPSS 24. The robust maximum likelihood was used for the estimation due to the multivariate normality assumption violation. A two-factor model was tested for measurement model validity and construct validity for each of the attitude and practice domains.

    RESULTS: CFA of a 25-item in total, the two-factor model yielded adequate goodness-of-fit values. The measurement model also showed good convergent and discriminant validity after model re-specification. A two-factor model was tested for measurement model validity and construct validity for each of the attitude and practice domains. The result also showed a statistically significant value (p

    Depression is one of the leading causes of mortality and morbidity worldwide. In the year 2000 depression accounted for 4.4% of the global disability adjusted life years (DALYs). The Kingdom of Saudi Arabia (KSA) has a population of 28 million people and is one of the countries experiencing demographic transition in its population structure. Improvements in socioeconomic status have been shown to be associated with increased chronic diseases including chronic mental diseases like depression, but still there is no comprehensive review summarizing the various reports currently existing in the literature. Although individual studies within Saudi Arabia have reported prevalence rates and risks, the quality of such studies need to be subjected to rigorous assessment and their findings pooled to give combined weighted evidence that will provide basis for targeted intervention. Pooled risks have the advantage of adjusting inherent variations within sampled populations and therefore providing more reliable estimates even though there are concerns about possible magnification of smaller individual risks.

    Despite the medical, veterinary and forensic relevance of myiasis-causing flies, knowledge of their diversity in Saudi Arabia is limited especially in the southern region. Therefore, a survey of myiasis-causing flies in the Jazan region was carried out using Red Top Fly Catcher traps baited with either decomposing beef liver or a lure composed primarily from fishmeal during the period April 2013-March 2014. Twelve known species were identified and recorded in this study, seven species of them belonging to Calliphoridae (Chrysomya, Lucilia, and Hemipyrella) and five species belonging to Sarcophagidae (Sarcophaga). Two of these species were recorded for the first time for Saudi Arabia, namely Hemipyrella pulchra (Wiedemann, 1830) and Sarcophaga (Liosarcophaga) exuberans Pandellé, 1896. Images of the species recorded are also provided for the first time. The results expand the knowledge of geographical distribution, fauna, and habitat of the myiasis-causing flies in Saudi Arabia. Biological information and world-wide geographical distribution of these species are included together with some taxonomic remarks.

    The heavy metal (HM) pollution in sediment is of serious concern, particularly in the Red Sea environment. This study aimed to review and compile data on the concentrations of four HMs (Cd, Cu, Pb, and Zn) in the coastal surface sediments from the Red Sea, mainly from Saudi Arabia, Egypt, and Yemen, published in the literature from 1992 to 2021. The coastal sediments included those from mangrove, estuaries, and intertidal ecosystems. It was found that the mean values of Cd, Cu, Pb, and Zn in coastal Red Sea sediments were elevated and localized in high human activity sites in comparison to the earth upper continental crust and to reference values for marine sediments. From the potential ecological risk index (PERI) aspect, 32 reports (47.1%) were categorized as 'considerable ecological risk' and 23 reports (33.8%) as 'very high ecological risk'. From the human health risk assessment (HHRA) aspect, the non-carcinogenic risk (NCR) values (HI values < 1.0) of Cd, Cu, Pb, and Zn represented no NCR for the ingestion and the dermal contact routes for sediments from the Red Sea countries. The reassessment of the HM data cited in the literature allowed integrative and accurate comparisons of the PERI and HHRA data, which would be useful in the management and sustainable development of the Red Sea area, besides being a helpful database for future use. This warrants extensive and continuous monitoring studies to understand the current and the projected HM pollution situation and to propose possible protective and conservative measures in the future for the resource-rich Red Sea ecosystem.

    The acceleration of growth in the population in Saudi Arabia and the increase in municipal solid waste generation have caused a problem in Dammam city: an increase in solid waste production. Therefore, solid waste sorting is an important practice of municipal solid waste management. The main objectives in this research are understanding the effect of internal and external factors on household willingness in sorting waste in Dammam city and studying the attempts to construct a theoretical research model by adding market incentives, government facilitators, and awareness into the popular planned behaviour theory to explain residents' waste sorting intentions. The data collection and analysis are based on the questionnaire study, which is based on the questionnaire survey data from 450 households in Dammam. This study revealed that social influence significantly predicts households' willingness to sort and recycle, that is, to promote recycling. Additionally, the variable social influence has a significant but low influence on households' willingness to sort and recycle. The result of the structural equation model shows that perceived behavioural control significantly predicts households' willingness to sort and recycle waste. This finding is consistent with the theoretical expectation. Therefore, this research shows that attitude, social influence, perceived behavioural control, market incentives, government facilitators and awareness positively and significantly affect residents' waste sorting intentions. Additionally, this research corroborates the discrepancy between internal and external variables.

    Background: Working conditions, job satisfaction, and their overall impact on a dentist's job satisfaction are critical for future employment and retaining of dentists.

    Objectives: This study is aimed at determining the factors influencing the job satisfaction level among dentists. It is also aimed at evaluating how personal (age, gender) and professional (type, type of qualification, and year of practice) characteristics influence overall job satisfaction.

    Methods: For data collection, a structured self-administered questionnaire was used, in which one part collected information on personal characteristics. At the same time, the other contained a questionnaire related to job satisfaction. The German validated version of the questionnaire had a 10-point Warr-Cook-Wall (WCW) scale developed by Warr et al. in 1979. Each item was rated on a 5-point Likert scale, with 5 representing excessive satisfaction and 1 representing extreme dissatisfaction.

    Results: The results revealed that dentists in Saudi Arabia have a higher satisfaction level with "colleagues and fellow workers" (26.5%). The relation between the years of practice was highly significant. However, they were dissatisfied with their "income" (22.6%), and when compared with concerning age, gender, profession, and their practice years, this finding was highly significant.

    Conclusion: A higher percentage of satisfaction was seen with the "fellow and colleague's workers" dimension. At the same time, "income" was the aspect with which the dentists showed extreme dissatisfaction.

    AIM: To determine dental arch relationships of Saudi children born with nonsyndromic complete unilateral cleft lip and palate (UCLP).

    MATERIAL AND METHODS: This is a retrospective cohort study that comprised dental study models of 74 UCLP Saudi children aged 8-10 years who were recruited from 14 referral cleft centers. All participants had their cleft lip and palate repaired with no history of alveolar bone graft or any orthodontic treatment. Dental arch relationships of UCLP patients were assessed using the Great Ormond Street, London, and Oslo (GOSLON) Yardstick-a clinical tool that categorizes dental relationships of UCLP children into five discrete grades from I to V. The reliability of the rating was assessed with weighted kappa (κ) statistics.

    RESULTS: Three children (4.1%) had excellent surgical outcomes (grade I), 18 children (24.3%) filled into grade II (good outcome), 22 subjects (29.7%) had grade III (fair outcome), 27 children (36.5%) had grade IV (poor outcome), and 4 subjects (5.4%) were ranked as having very poor outcomes (grade V). The mean GOSLON score was 3.39. Intrarater and interrater agreements were high indicating good reproducibility.

    CONCLUSION: Based on the dental arch relationships, the treatment outcome of UCLP Saudi children was unsatisfactory, with a mean GOSLON score of 3.39. Delayed palate repair and the use of presurgical orthopedics may be considered in the future for cleft deformity management.

    CLINICAL SIGNIFICANCE: To address the effect of particular cleft surgical protocol on dental arch relationships of UCLP patients. How to cite this article: Alforaidi S, Zreaqat M, Hassan R.

    BACKGROUND: During the past two decades, various sectors and industries have undergone digital transformation. Healthcare is poised to make a full transformation in the near future. Although steps have been taken toward creating an infrastructure for digital health in the Middle East, as it stands, digital health is still an emerging field here. The current global health care crisis has underscoredthe need for digitization of the healthcare sector to provide high-value, high-quality care and knowledge generation. With the advent of digital transformation in countries around the globe, there is a rising demand for investment and innovation in health information technology. With the demand for health informatics (HI) graduates in different disciplines (e.g., healthcare professions, information technology, etc.), there is an urgent need to determine and regulate clear career pathways and the core competencies necessary for digital health professional to practice effectively and to allow technology to add value to the healthcare systems. Given the changing landscape of the profession, the Kingdom of Saudi Arabia (KSA) and the Gulf Cooperation Council (GCC) countries are experiencing a rising demand to produce digital health professionals who can meet the needs of all the stakeholders involved, including patients, healthcare professionals, managers, and policymakers. However, despite the number of region-wide initiatives in the form of training programs, there remains a knowledge-practice gap and unclear job roles within the HI community. In recent years, regional digital health workforce initiatives have been put forward, such as the GCC Taskforce on Workforce Development in Digital Healthcare. The taskforce initiated a survey and several workshops to identify and classify HI disciplines according to the needs of the job market and through comparisons with similar efforts developed across the globe, such as the TIGER project and the EU*US eHealth Work project. Digital health implementation has been flourishing in the Middle East for the past 15 years. During this period, while digital health professions have been thriving in the industry to deliver tools and technologies, academic institutions have offered some amount of training and education in digital health; however, the career pathway for digital health professionals is not clear due to mismatch about the qualifications, skills, competencies and experience needed by the healthcare industry.

    OBJECTIVES: Due to this discrepancy between the academic curriculum and the skills needed in the healthcare industry, the objectives of this study are to define the career pathway for eHealth professions and identify the challenges experienced by academic institutions and the industry in describing digital health professionals.

    METHODS: We elicited qualitative data by conducting six focus groups with individuals from different professional backgrounds, including healthcare workers, information managers, computer sciences professionals, and workers in the revenue cycle who participated in a workshop on November 2-3, 2019, in Dubai. All focus group sessions were audio-recorded and transcribed, and participants were de-identified before analysis. An exploratory method was used to identify themes and subthemes. Saturation was reached when similar responses were found during the analysis. In this study, we found that respondents clearly defined eHealth career pathways based on criteria that included qualifications, experience, job scope, and competency. We also explored the challenges that the respondents encountered, including differences in the required skill sets and training and the need to standardize the academic curriculum across the GCC region, to recognize the various career pathways, and to develop local training programs. Additionally, country-specific projects have been initiated, such as the competency-based Digital Health framework, which was developed by the Saudi Commission of Healthcare Specialties (SCFHS) in 2018. Competency-based digital health frameworks generally include relevant job definitions, roles, and recommended competencies. Both the GCC taskforce and the Saudi studies capitalized on previous efforts by professional organizations, including Canada's Digital Health formerly known as (COACH), the U.S. Office of the National Coordinator for Health Information Technology (ONC), the American Medical Informatics Association (AMIA), and the Health Information and Management Systems Society (HIMSS).

    RESULTS: In this study, we found that respondents defined eHealth career pathways based on different criteria such as: qualifications; various background of health and IT in the HI field; work experiences; job scope and competency. We also further explore the challenges that the respondents encountered which delineates four key aspects such as need of hybrid skills to manage the digital transformation, need of standardization of academic curriculum across GCC, recognition of the career pathways by the industry in order to open up career opportunity and career advancement, and availability of local training programs for up-skilling the current health workforce.

    CONCLUSION: We believe that successful health digital transformation is not limited to technology advancement but requires an adaptive change in: the related competency-based frameworks, the organisation of work and career paths for eHealth professionals, and the development of educational programmes and joint degrees to equip clinicians with understanding of technology, and informaticians with understanding of healthcare. We anticipate that this work will be expanded and adopted by relevant professional and scientific bodies in the GCC region.

    OBJECTIVES: Dyslipidemia is a prevalent condition with significant morbidity and mortality across the world, including in the Arabian Gulf. The present study aimed to describe the characteristics of patients receiving evolocumab in clinical practice.

    METHODS: ZERBINI was a multi-country, observational, retrospective/prospective study of subjects receiving evolocumab as part of routine clinical management of their hyperlipidemia. This regional publication reports on adult participants from Saudi Arabia and Kuwait who have had ≥1 dose of evolocumab before enrollment and ≤6 months' prior exposure to evolocumab. Patient characteristics and treatment persistence data were collected in addition to baseline and follow-up data up to 12 months post-evolocumab initiation.

    RESULTS: Overall, 225 patients were included from two sites, Saudi Arabia (N = 155) and Kuwait (N = 70). Mean age was comparable across sites and most patients had baseline coronary artery disease and/or hypertension. Baseline LDL-C levels (mean ± SD 3.6 ± 1.4 mmol/L in Saudi Arabia, 3.1 ± 1.4 mmol/L in Kuwait) were reduced by approximately 57%-62% in the first 6 months after evolocumab initiation (1.5 ± 1.2 mmol/L in Saudi Arabia [n = 63], 1.2 ± 0.8 mmol/L in Kuwait [n = 28]). This decrease was maintained over the 12-month follow-up period. Most patients achieved ACC 2018 LDL-C goals (<1.8 mmol/L; 74.6% in Saudi Arabia, 93.1% in Kuwait) and ESC 2019 LDL-C goals (<1.4 mmol/L; 66.7% in Saudi Arabia, 75.9% in Kuwait) in the first 6 months after evolocumab initiation. Medication persistence with evolocumab was high (up to 90.7%). Evolocumab had a favorable safety profile and no treatment-emergent adverse events were observed at either site.

    CONCLUSION: Evolocumab is an effective lipid-lowering treatment in local populations. LDL-C goal achievement is increased when evolocumab is added to background lipid-lowering therapy with high tolerability and persistence. Long-term follow-up and large-scale data are needed to further support these observations.

    This cluster-randomized study aimed to evaluate the effects of an intervention focused on physical activity, nutrition, and body image perception among girls in intermediate schools in Saudi Arabia. A seminar was delivered to the mothers of the girls in the experimental group. The experimental group then attended six interactive sessions within 3 months featuring physical activity, nutrition, and body image perception, followed by a 3-month follow-up period. A total of 138 respondents (68 in the experimental group and 70 in the control group) completed the intervention. Each participant's body mass index-for-age z-score and waist circumference were measured, and they completed a physical activity, sedentary behavior, and body image perception questionnaires before and after the intervention and at the follow-up. The intervention was evaluated using within- and between-groups generalized estimating equations. There were no significant changes in the respondents' body mass index-for-age z-score or waist circumference (p > 0.05). However, immediate significant improvements were seen in physical activity, sedentary behavior, and body image satisfaction among the experimental group, and these improvements remained at follow-up (p < 0.001). These differences were more significant among the experimental group than among the control group. We found this intervention effective. Future studies can adapt this intervention for adolescent boys and extend its duration to improve the body mass index outcome.

    Current strategies for tick control have led to the development of resistance and environmental contamination. Consequently, there is an urgent need for research into new and effective acaricides for tick control. The aim of this study was to fabricate and characterize Linalool loaded zinc oxide nanoparticles (Lin@ZNP), and to assess the acaricidal, larvacidal, and repellent activities of Lin@ ZNP against Hyalomma anatolicum, a prevalent tick species infesting cattle in Saudi Arabia. Lin@ ZNP was synthesized using an ethanolic solution of polyvinyl alcohol. The adult immersion, the larval packet, and the assessment of vertical movement behavior of tick larvae assays were utilized to examine the acaricidal, larvicidal, and repellent activities of Lin@ZNP against H. anatolicum, respectively. Furthermore, the impact of Lin@ZNP on acetylcholinesterase and oxidant/antioxidant enzyme activities was investigated. Exposure of adult H. anatolicum to different concentrations of Lin@ZNP resulted in noticeable (p<0.001) reductions in the viability rate of adults and the mean number, weight, and hatchability of eggs, compared to the control group. Lin@ZNP demonstrated significant repellent effects on H. anatolicum larvae after 60, 120, and 180 minutes of exposure. Lin@ZNP, particularly at all concentrations, markedly suppressed the acetylcholinesterase activity of the larval stage of H. anatolicum (P<0.001); but increase in malondialdehyde (MDA) levels (P<0.001) and a decrease in glutathione-S-transferase (GST) levels in H. anatolicum larvae (P<0.001). Lin@ZNP exhibited considerable acaricidal, larvicidal, and repellent effects against H. dromedarii adults and larvae in a manner dependent on the dosage. Additionally, Lin@ZNP notably reduced AChE levels and antioxidant activity, while inducing oxidative stress in H. anatolicum larvae. Nevertheless, further research is necessary to elucidate the precise mechanisms and practical efficacy of Lin@ZNP.

    Introgression between genetically distinct populations generates variation that may promote adaptation to diverse environmental conditions. In the mosquito Aedes aegypti, the forest-associated subspecies Aedes aegypti formosus (Aaf) underwent a domestication process approximately 5000 years ago, giving rise to the globally invasive, human-associated arbovirus vector Aedes aegypti aegypti (Aaa). Despite extensive human-mediated transport, the two subspecies remain largely distinct, with admixture documented mainly in coastal Africa and Saudi Arabia. We examined Saudi Arabian Ae. aegypti across climatically contrasting regions - the humid south and arid west- using a Saudi Arabian dataset (11,939 SNPs) to examine within-country genetic and environmental variation and a global dataset (13,455 SNPs) to assess ancestry and admixture in a worldwide context. Genomic analyses revealed strong west-south differentiation, with Jazan Highland showing admixture between subspecies and the highest proportion of Aaf ancestry. Multiple pulses of gene flow into and within southern Saudi Arabia suggest Aaf populations act as a reservoir of genetic variation. Genome-wide scans identified a candidate region associated with the humidity gradient, harbouring an elongase of very long-chain fatty acids (AAEL024147), essential for cuticle production and minimizing water loss. Because the Saudi Arabian genetic background is predominantly the arid-adapted subspecies Aaa, the presence of Aaf ancestry at this locus may reflect localized introgression with adaptive relevance under an increasingly humid environment. Our findings highlight how secondary contact between divergent lineages may contribute to local adaptation in Ae. aegypti, with implications for predicting responses to environmental change.
