    AIM AND OBJECTIVE: Epidemiological studies of sleep disturbances are essential to promote awareness among families and educational officials and deliver appropriate treatment at a very early timing. The aim of this population-based study was to determine the frequency of sleep-disordered breathing (SDB) symptoms and its association with obesity among schoolchildren in West Saudi Arabia.

    MATERIALS AND METHODS: This cross-sectional study comprised 2,000 schoolchildren aged 6-12 years. Sleep-disordered breathing symptoms were assessed with Arabic version of Pediatric Sleep Questionnaire (PSQ). Overweight/obesity was evaluated using body mass index (BMI) and their association with SDB was tested using a regression analysis model.

    RESULTS: Overall, 23% of children were at high risk of SDB. Prevalence of habitual snoring was 15.9% and sleep apnea 4%. Boys were at higher risk of SDB than girls (p = 0.026), while age had no effect (p = 0.254). High-risk SDB had a strong association with sleep symptoms compared to low-risk SDB (p < 0.05). Sleep-disordered breathing increased significantly in overweight and obese children (p = 0.017 and p < 0.001, respectively).

    CONCLUSION: Around 23% Saudi schoolchildren are at risk of SDB. Related symptoms were strongly associated with high risk of SDB. Overweight and obesity had a strong and progressive association with SDB.

    CLINICAL SIGNIFICANCE: The results will help in identifying children at high risk of developing SDB and plan for early intervention to avoid the progression of SDB later in life.

    Overweight and obesity are becoming increasingly prevalent among children and adolescents in Saudi Arabia and are an emerging cause of non-communicable diseases (NCDs). Lifestyle factors, such as insufficient levels of physical activity and sedentary behaviors, are responsible for the increased prevalence of NCDs. This study aimed to determine the association between physical activity levels, sedentary behaviors, and anthropometric measurements in Saudi female adolescents. A cross-sectional study was carried out among 399 healthy female adolescent students aged 13-14 years in Arar, Saudi Arabia. The participants were randomly selected from different schools and their anthropometric measurements were determined. The Physical Activity Questionnaire for Older Children (PAQ-C) and the Adolescent Sedentary Activity Questionnaire (ASAQ) were used to assess their physical activity levels and sedentary behaviors, and an analysis was conducted using IBM SPSS software version 25. A multiple linear regression model was used to determine the association between the variables. The majority of the participants had a normal body mass index (BMI; 79.4%) and waist circumference (WC; 62.4%). A total of 74.4% had waist to height ratio (WHtR) < 0.5. About 92.7% of the participants were not meeting PA recommendations of 60 min of moderate to vigorous physical activity daily. The overall mean time spent on sedentary activities was high on both weekdays and weekend days at 357.64 ± 86.29 and 470.51 ± 147.64 min/day, respectively. Moreover, anthropometric measurement (BMI) was positively associated with age and negatively associated with sedentary behavior on weekends, while WHtR was positively associated with age. The multiple linear regression analysis also showed that age and sedentary behavior significantly predicted BMI among the study participants (F (2, 396) = 4.346, p < 0.014) and age was the only significant predictor of WHtR (F (1, 397) = 16.191, p ≤ 0.001). This study revealed that most of the female Saudi adolescents undertook low levels of activity and high levels of sedentary behaviors. Sedentary behaviors were significantly associated with their BMI. Accordingly, an intervention program on healthy lifestyles is important to improve Saudi female adolescents' lifestyles.

    INTRODUCTION: Middle East respiratory syndrome (MERS) is a viral respiratory infection caused by the MERS-CoV. MERS was first reported in the Kingdom of Saudi Arabia in 2012. Every year, the Hajj pilgrimage to Mecca attracts more than two million pilgrims from 184 countries, making it one of the largest annual religious mass gatherings (MGs) worldwide. MGs in confined areas with a high number of pilgrims' movements worldwide continues to elicit significant global public health concerns. MERCURIAL was designed by adopting a seroconversion surveillance approach to provide multiyear evidence of MG-associated MERS-CoV seroconversion among the Malaysian Hajj pilgrims.

    METHODS AND ANALYSIS: MERCURIAL is an ongoing multiyear prospective cohort study. Every year, for the next 5 years, a cohort of 1000 Hajj pilgrims was enrolled beginning in the 2016 Hajj pilgrimage season. Pre-Hajj and post-Hajj serum samples were obtained and serologically analysed for evidence of MERS-CoV seroconversion. Sociodemographic data, underlying medical conditions, symptoms experienced during Hajj pilgrimage, and exposure to camel and untreated camel products were recorded using structured pre-Hajj and post-Hajj questionnaires. The possible risk factors associated with the seroconversion data were analysed using univariate and multivariate logistic regression. The primary outcome of this study is to better enhance our understanding of the potential threat of MERS-CoV spreading through MG beyond the Middle East.

    ETHICS AND DISSEMINATION: This study has obtained ethical approval from the Medical Research and Ethics Committee (MREC), Ministry of Health Malaysia. Results from the study will be submitted for publication in peer-reviewed journals and presented in conferences and scientific meetings.

    OBJECTIVE: The aim of the study is to evaluate the awareness, comportment and attitude/perception of dentists regarding the use of photodynamic (PD) therapy before and during COVID-19 pandemic around the globe.

    SUBJECTS AND METHODS: An online survey was performed by sending out an online questionnaire comprising 21 questions among dental practitioners working in four different countries: Saudi Arabia, Pakistan, Malaysia and United Kingdom. The survey evaluated dental practitioners' level of awareness about the PD therapy, comportment and attitude for its implication and prevalence in daily clinical practice. For statistical significance the Chi-square analysis with Spearman Correlation coefficient was conducted to assess the sub-groups and correlating the factors with the level of awareness of the dental practitioners.

    RESULTS: A total of 1,219 dental practitioners from four different countries (Saudi Arabia, Pakistan, Malaysia and United Kingdom) responded to the questionnaire. The median age of the respondents was 37, 34, 36 and 39 respectively. The majority of dental practitioners demonstrated to have an acceptable level of awareness regarding PD therapy. Nearly 76%, 74%, 79% and 80% of the individuals from Saudi Arabia, Pakistan, Malaysia and United Kingdom respectively were aware of the role/mechanism of action of the PD therapy. Moreover, in preponderance, practitioners were confident that the effect of PD therapy will not be reduced in patients infected with COVID-19. The majority of dental practitioners were convinced that successful dental treatment due to PD therapy is linked majorly with therapies done in relation to four major dental specialties: prosthodontics, endodontic, restorative dentistry and periodontology. Approximately more than 90% of the dentists were sure that the rate of COVID-19 transmission can be reduced by using PD therapy in oral treatments. The dental practitioners from Saudi Arabia (91%), Pakistan (82%), Malaysia (83%) and United Kingdom (82%) were contented to learn about PD therapy for its use in clinical practice. Nearly more than 95% of the practitioners from the four countries were keen to attend the lectures/hands-on workshops regarding PD therapy to enhance their skills and knowledge. More than 80% of dentists do not refuse the peripheral role of PD therapy with their patients.

    CONCLUSIONS: The respondents from the four countries displayed passable level of awareness regarding basic information of PD therapy and its clinical implication in dental specialty. Nevertheless, there is a need to develop awareness regarding the use of PD therapy among dental practitioners during their undergraduate program. Furthermore, lectures and hands-on workshops should be arranged to train dental practitioners in order to enhance their skills for its solicitation in clinical practice. It is perceived by the dentists in the four countries that the use of PD therapy can effectively reduce COVID-19 rate of transmission.

    INTRODUCTION: Awareness of screening procedures and illness warning signals is critical for expanding and implementing screening programs in society, which would improve the odds of early identification of breast cancer.

    OBJECTIVES: This study aimed to evaluate the knowledge, awareness, attitudes, and practices related to breast cancer risk factors, signs, symptoms and methods of screening among female faculty and students at Hail University in the Kingdom of Saudi Arabia.

    METHODS: A cross-sectional study was conducted from January 2021 through February 2021 in the Hail region of Saudi Arabia. A closed-ended questionnaire, which consisted of 37 questions, was distributed online (using a Google Forms link) in both English and Arabic languages. Data was collected from 425 female subjects who participated in the study.

    RESULTS: The study showed an overall knowledge level of 46.36% regarding breast cancer. Participants had average knowledge about risk factors, signs, and symptoms, whereas their awareness and practice of breast self-examination and screening methods were weak.

    CONCLUSION: The current study concluded that public awareness of breast cancer remains relatively low, and Saudi Arabia still needs several public awareness initiatives using mass media, such as television, the Internet, and radio, as well as social media. Special awareness programs should also be held in places where a large number of women can easily be reached, such as colleges, universities, and hospitals.

    INTRODUCTION: Testicular cancer (TC) incidence is increasing worldwide. This study aimed to investigate Saudi nursing students' knowledge and perception about TC.

    METHOD: This cross-sectional study was done using convenience sampling method. In this study, 280 nursing students from different nursing schools in six cities of Saudi Arabia were recruited. A structured self-report questionnaire was used to collect data.

    RESULT: About 49.2% of the participants received education about TC in their nursing schools. The findings showed lack of enough knowledge about TC among Saudi nursing students. Mostly, the participants reported that heredity factor and having family history of TC (48.9%) and age between 56 and 70 years (41.8%) were the most common risk factors of TC. According to the participants, physical examination was the most common diagnostic test usually used for early detection of TC (40.4%) and biopsy test was the most accurate test to confirm TC diagnosis (45.4%). Only one third of the participants (34.6%) knew that between 75% and 100% of TC cases can be cured in case of early detection. About half of the participants (51.8%) reported that surgical procedure was the most common treatment for TC. The nursing students who had high GPA (r=0.86, p<0.001), were unwilling to get more information on TC (r=0.24, p=0.04), had family history of TC (r= 0.53, p=0.02), medical problems with testicles (r= 0.69, p=0.01), received education about TC in their school of nursing (r=0.65, p=0.02), and were more self-confident in assessing and managing TC (r=0.38, p=0.03) had higher level knowledge about TC.  Conclusion: Despite the importance of nurses' roles in assessing and managing TC, nursing students in Saudi Arabia still did not have enough knowledge about TC. Improving nursing programs' curricula and conducting health education programs are recommended.

    A total of 227 Plasmodium falciparum isolates from Jazan region, southwestern Saudi Arabia were amplified for the P. falciparum multi-drug resistance 1 (pfmdr1) gene to detect point mutations 11 years after the introduction of artemisinin-based combination therapy (ACT) in Saudi Arabia. The pfmdr1 86Y mutation was found in 11.5% (26/227) of the isolates while the N86 wild allele was detected in 88.5%. Moreover, 184F point mutations dominated (86.3%) the instances of pfmdr1 polymorphism while no mutation was observed at codons 1034, 1042 and 1246. Three pfmdr1 haplotypes were identified, NFSND (74.9%), NYSND (13.7%) and YFSND (11.4%). Associations of the prevalence of 86Y mutation and YFSND haplotype with participants' nationality, residency and parasitaemia level were found to be significant (P

    OBJECTIVE: The current study aims to define patient-centred infertility care (PCIC) from the perspective of Arab women with infertility.

    DESIGN: Semistructured in-depth telephone interviews.

    SETTING: Hospitals providing infertility care, Jeddah, Saudi Arabia.

    PARTICIPANTS: Arab women who received infertility treatment during the 6 months preceding the interview at any hospital in Jeddah, Saudi Arabia. Interviews were conducted with Arab women experiencing infertility from January 2017 to December 2018. A purposive sample of 14 women were included in the final analysis with maximum variation.

    RESULTS: Participants highlighted nine important PCIC dimensions. Of these, four were agreed on by all participants: accessibility, minimising cost, information and education, and staff attitudes and communication. The remaining five dimensions were staff competence, physical comfort, privacy, psychological and emotional support, and continuity and coordination of care. The concept of PCIC was related to three major contributors: participants' demographics, patient experience with infertility care and health-seeking behaviour.

    CONCLUSIONS: The current study provided nine PCIC dimensions and items, which can guide efforts to improve the quality of infertility care in Arab countries in two ways: first, by raising infertility care providers' awareness of their patients' needs, and second, by developing a validated tool based on the dimensions for measuring PCIC from Arab patients' perspective. Clear differences between the Arab and the European PCIC model were found. Our findings concluded that women continued to exhibit basic unmet needs.

    This paper explains Needlestick and Sharp Injuries among Healthcare Workers in Saudi Hospitals. Presently there are number of factors that are responsible for health care workers injuries. Lack of secure environment and ignorance to safety measures can lead to injuries due to Needlestick and Sharp objects. There is a significant need of providing better working environment for health care workers in Saudi Arabia. Following daily practices and World Health Organization’s measures for taking the preventive steps for these injuries is necessary. Trying to avoid utilizing needles whenever secure and efficient substitutes are present, providing needle containers, avoiding re-capping and wearing gloves on both hands are some of the measures that could be taken to make sure these problems do not recur.

    We conducted a multi-institutional case study to identify the issues associated with the adoption of information and communication technology (ICT) in five private care hospitals in the Kingdom of Saudi Arabia. We conducted interviews with 37 respondents primarily comprising IT professionals.
    We found that there were three determinants of behavioural intentions in this case study: organisation objectives, facilitating conditions and social influence where there are no effects of performance expectancy or effort expectancy. In all five cases, none of the moderators (age, gender, experience and voluntariness) in the original united theory of acceptance and use of technology model were considered critically important by IT professionals. In the present paper, all qualitative elements such as themes, patterns and overarching in the data were analysed to reach a conclusion. In addition, the various perspectives of using ICT are discussed.

    This study presents a preliminary assessment of biodiesel production from waste sources available in the Kingdom of Saudi Arabia (KSA) for energy generation and solution for waste disposal issues. A case study was developed under three different scenarios: (S1) KSA population only in 2017, (S2) KSA population and pilgrims in 2017, and (S3) KSA population and pilgrims by 2030 using the fat fraction of the municipal solid waste. It was estimated that S1, S2, and S3 scenarios could produce around 1.08, 1.10 and 1.41 million tons of biodiesel with the energy potential of 43423, 43949 and 56493 TJ respectively. Furthermore, annual savings of US $55.89, 56.56 and 72.71 million can be generated from landfill diversion of food waste and added to the country's economy. However, there are challenges in commercialization of waste to biodiesel facilities in KSA, including waste collection and separation, impurities, reactor design and biodiesel quality.

    Background and Objectives: There are no guidelines on the regenerative endodontic procedures that should be followed in dental treatment. Thus, it is essential to learn the knowledge, attitudes, and opinions about regenerative endodontics among dental practitioners, particularly endodontists, as they are the first providers of this type of dental treatment. Aim: This study aimed to assess the knowledge and attitudes among residents of the Saudi Board of Advanced Restorative Dentistry (SBARD) in Saudi Arabia. Methods & Materials: A questionnaire-based survey was conducted among 128 residents of endodontics, pedodontics, and the SBARD in Saudi Arabia. The questionnaire was distributed to participants using the available electronic measures such as emails and social media. The questionnaire was made by Google Forms, and responses were received directly in the excel sheet in the email. The data were exported as an excel file, coded, and analyzed, and the p-value < 0.05 was set as significant. Results: More than 50% (74 dentists) of the participants reported receiving continuing education in regenerative treatment, with a significant difference found among specialty (p = 0.023). No significant association was found between knowledge, gender, and type of postgraduate study. The vast majority (89.1%) of the participants believed regenerative endodontics should be incorporated into dentistry curricula. About two-thirds (78.2%) of the participants declared their ability to attend future training courses in a regenerative endodontic, whereas 10.9% did not, and 10.9% were unsure. Conclusions: The dental practitioners were enthusiastic and interested in regenerative and stem cell treatment. The results also suggested incorporating regenerative treatment into the dental curriculum and signaled the need for more continued training courses.

    INTRODUCTION: Professionalism is a crucial component of medical practice. It is a culturally sensitive notion that generally consists of behaviors, values, communication, and relationships. This study is a qualitative study exploring physician professionalism from the patients' perspective.

    METHODS: Focus group discussions with patients attending a family medicine center attached to a tertiary care hospital were carried out using the four gates model of Arabian medical professionalism that is appropriate to Arab culture. Discussions with patients were recorded and transcribed. Data were thematically analyzed using NVivo software.

    RESULTS: Three main themes emerged from the data. (1) In dealing with patients, participants expected respect but understood delays in seeing physicians due to their busy schedules. In communication, participants expected to be informed about their health conditions and to have their questions answered. (2) In dealing with tasks, participants expected proper examination and transparency of diagnosis, but some expected the physician to know everything and did not appreciate them seeking outside opinions. They expected to see the same physician at every visit. (3) In physician characteristics preferences, participants preferred friendly smiling physicians. Some cared about the outer appearance of the physician whereas others did not.

    DISCUSSION/CONCLUSIONS: The findings of the study explained only two themes of the four gates model namely dealing with patients and dealing with tasks. Cultural competence and how to benefit from patients' perceptions to be an ideal physician should be incorporated into the process of physicians' training.

    BACKGROUND: Lifestyle changes in Saudi Arabia have affected the dietary intake of adolescents, who now consume more unhealthy foods.

    AIMS: We assessed the dietary intake of female Saudi Arabian adolescents living in Arar.

    METHOD: In this randomised cluster study, female students were selected randomly from assigned schools to form the intervention (n = 68) and control (n = 70) groups. Initially, a 60-minute seminar was held for mothers of students in the intervention group. Subsequently, 6 90-minute sessions were held over 3 months for the intervention group on topics such as food groups, healthy and unhealthy eating, body image and physical activity. The data were analysed using generalized estimating equations.

    RESULTS: The interaction effect (group by time) between the groups revealed statistically significant differences for dairy products (P < 0.001), sweetened beverages (P < 0.001), sweetened baked goods (P = 0.022) and fruits and vegetables (P < 0.003). The intervention significantly increased the intake of dairy products (P < 0.001) and fruits and vegetables (P = 0.003). It reduced the intake of sweetened beverages (P < 0.001) and sweetened baked goods (P = 0.010) in the intervention group.

    CONCLUSION: This intervention showed a grater positive effect on the intervention than the control group; it increased dietary intake of dairy products, fruits and vegetables, and reduced intake of sweetened beverages and sweetened baked goods among the intervention group participants. We recommend similar nutrition interventions among other young Saudi Arabian population groups to prevent obesity and other diseases.

    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.

    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.
