Predicting the Orientation of Vehicle Drivers towards the Traffic and Speed Enforcement Surveillance System

Background A traffic and speed enforcement system in the Kingdom of Saudi Arabia known as Saher employs traffic monitoring and speed enforcement around the clock using surveillance cameras. Vehicle drivers' attitudes towards this system vary due to several variables. Objective The study investigates the impact on the prediction of male vehicle drivers’ orientation towards the application of the Saher system and whether there is a difference in the vehicle drivers’ orientation toward the system over time (five years later). Methods The study sample consisted of 761 participants from Imam Abdulrahman bin Faisal University. The quantitative approach was a questionnaire titled “Vehicle Drivers’ Orientation towards the Application of the Traffic and Speed Enforcement Surveillance System (Saher)”, which was applied in 2016 and 2021. Results The psychometric characteristics of the study tool were ascertained, the data was quantitatively analyzed, and the results showed that vehicle drivers’ orientations toward the Saher system were positive, the nationality and number and type of violation contribute to predicting their orientation toward the system at varying rates, and the orientation of vehicle drivers toward the system improved five years later. Conclusion The study recommends conducting a study with wider societal segments, including women who started driving in Saudi Arabia in 2018, while also focusing on the qualitative aspect of the analysis of the study findings, taking testimonials of the groups that have been involved in accidents and families of groups who have suffered from deaths in order to determine their orientations towards the system.

Digital impression perception among dental students in Saudi Arabia: A cross-sectional study.

The use of digital dentistry is rapidly increasing in prosthodontics. However, most dental students are not familiar with applying digital technologies in dental clinics. Thus, the aim of the current study was to assess the perception of dental students at different educational years towards digital impressions in comparison to conventional impressions. A cross-sectional questionnaire-based study was conducted on various educational years of dental students in the College of Dentistry, Imam Abdulrahman Bin Faisal University, between February and April 2023. The students had performed at least one intraoral scan (Trios 3shape) and another conventional polyether impression for phantom casts/patients. The questionnaire assessed students' perceptions of digital impressions using a 5-point scale ranging from strongly agree to strongly disagree. Mann-Whitney U and Kruskal-Wallis tests were used to compare students' perceptions of digital impressions according to gender and educational year, respectively. The study included 122 students. About 55% were females with a mean (SD) age = 22.51 (3.36). Most students thought that digital impressions are faster and more user-friendly compared to conventional impressions. Significantly more female students thought that the handpiece was too big for intraoral use (p = 0.04) and that the process of the software was time-consuming and complicated. In general, higher educational year students were more satisfied with the digital impressions than lower educational year students. Digital impressions were perceived by most students as being faster and easier than conventional ones. However, male students and those with higher educational years showed better perception of digital impression.

Enhancing Oral Health via the Sense of Coherence Approach Among Adult Patients at University Dental Hospital.

The purpose of the study was to assess the sense of coherence and its relationship with oral health and other study variables among adult patients at university dental hospital. This cross-sectional study included adult patients visiting the Dental Hospital of the College of Dentistry, Imam Abdulrahman Bin Faisal University, Dammam. Sense of coherence was determined by Antonovsky's Sense of Coherence scale (SOC-13), which consists of 13 items on a 7-point Likert. DMFT index, plaque index, gingival index, and simplified oral hygiene index were used to evaluate the oral health of study participants. Bivariate and multivariable analyses were performed, and 0.05 level of significance was used in the study. The study included the data of 558 participants with a mean age of 32.19±10.11 years. The mean score of SOC was 52.77±13.11, which was significantly higher in high-income participants (P <0.001), participants without a medical condition (P=0.021), non-smokers (P <0.001), and those who visited the dentist in less than one year (P=0.028). Bivariate analysis showed statistically significant negative correlations between SOC and DMFT index (P=0.002), SOC and plaque index (P <0.001), SOC and gingival index (P=0.002), and SOC and simplified oral hygiene index (P=0.001). Multivariable analysis also showed that SOC was significantly correlated with DMFT index (P=0.001), plaque index (P <0.001), gingival index (P <0.001), and oral hygiene index (P=0.004) after controlling for age, gender, education, and monthly income. This study found that high-income and healthy participants, non-smokers, and those who visited the dental office during the last one year demonstrated significantly higher SOC. In addition, there was a statistically significant correlation between SOC and oral health. These study findings highlight the importance of raising awareness about SOC to improve oral health outcomes in adult patients.

Prevalence of Internet Addiction and Its Association with Psychological Disorders Among Medical Students in Saudi Arabia.

Internet addiction is increasing worldwide. Internet addiction (IA) refers to excessive Internet usage in an uncontrolled and time-consuming manner, causing loss of time and disruption of daily life. However, the prevalence of IA may vary according to age, sex, and ethnicity, and is more prevalent among college students. There is a strong link between problematic Internet usage and an increased risk of developing Post Traumatic Stress Disorder PTSD and depression symptoms. Medical students were chosen for this study due to their unique stressors, including rigorous academic demands, extensive study hours, and clinical practice requirements. It is critical to address behavioral addictions and their psychological effects in this group, as they are linked to the future quality of healthcare provision compared with their non-medical peers. To estimate the prevalence of Problematic Internet Use (PIU) in medical students and explore their correlation with the medical students' PTSD and Patient Health Questionnaire -9 (PHQ9) scores. A cross-sectional online survey was conducted including 506 medical students in the second year of medical school up to internship year at Imam Abdulrahman bin Faisal University (IAU) between June 2021 and January 2022. The questionnaire consisted of consent forms, sociodemographic data, and screening tools for PTSD, the GPIU, and PHQ-9. The prevalence of problematic internet usage (PIU) was 30.6% in the sample group. Students with moderate-to-moderately severe PTSD were 1.7 times more likely to have PIU OR (95% CI): 1.7 (1.091, 2.879). Students with moderate to severe depression were 2.2 times more likely to have PIU OR (95% CI); 2.2 (1.333, 3.950).Having a Saudi nationality, lower income, and being single was significantly associated with PIU. Single Saudi medical students with lower income are at risk of developing more problematic internet use. Especially those who score moderate to high on PTSD and PHQ-9 scales.

Iatrogenic pharyngo-esophageal diverticulum post-anterior cervical discectomy and fusion: A case report and review of literature.

The purpose of this study is to report a case of iatrogenic pharyngoesophageal diverticulum post-anterior cervical discectomy and fusion (ACDF) surgery, its management and management of postoperative complications. We also did a thorough review of literature about iatrogenic pharyngoesophageal diverticulum which is a rarely encountered complication occurring after a commonly performed surgery; ACDF. Here we describe a case of iatrogenic pharyngoesophageal diverticulum post-ACDF surgery. In this paper we also make comparisons to the 23 cases reported in the literature in terms of: presentations, clinical findings, management courses, and complications. This study was approved by the Institution Review Board of Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. (Ref. no.: IRB-2023-01-473). The reported subject provided written informed consent before initiation of this study. Our case is a 45-year-old male with a history of ACDF surgery 8 years ago. He presented with dysphagia and regurgitations which started 1 year after ACDF. He was labeled as a case of Zenker's diverticulum and underwent multiple failed open and endoscopic surgeries prior to presenting to us. Upon presenting to our center, barium swallow showed the pharyngoesophageal diverticulum. Patient definitive diagnosis of iatrogenic rather than Zenker's diverticulum was established intra-operatively with esophagoscopy which revealed exposed hardware inside the diverticulum. He underwent open diverticulectomy and diverticulopexy. Postoperatively he developed pharyngocutanous fistula and right vocal fold palsy, both successfully managed conservatively. Iatrogenic Pharyngoesophageal diverticulum is a rare complication following ACDF, however prolonged dysphagia shall warrant further investigation by contrast studies. Open diverticulectomy with muscle reinforcement is a good management modality. Due to the complicated anatomy secondary to previous operations, we recommend conservative management for patients with postoperative pharyngocutaneous fistula.

Impact of prosthetic rehabilitation on oral health-related quality of life of Saudi Adults: A prospective observational study with pre–post design

This study aimed to assess the impact of prosthetic treatment on the quality of life of partially/completely edentulous patients through the Oral Health Impact Profile-14 (OHIP-14) scale. This pre-post observational study was conducted in the College of Dentistry, Imam Abdulrahman Bin Faisal University, Saudi Arabia, between November 2022 and September 2023. Eligible participants were those aged between 26 and 80, in need of prosthetic treatment, and able to complete the questionnaire voluntarily. The questionnaire presented to the patients had two sections; the first included demographic and dentures-related variables, and the second included the OHIP-14 questionnaire. Differences in overall OHIP-14 scores after treatment about demographic and prosthesis-related factors were assessed using the Mann-Whitney U test/Kruskal Wallis test with a significance level of 0.05. Out of 108 participants, 65 were males, and 43 were females with an average age of 52 years with different prosthetic treatments (13.9 % fixed prostheses, 43.5 % removable partial, and 42.6 % complete dentures). 59.3 % brushed their teeth twice or more daily, and only 36.1 % checked them regularly. Comparison between the OHIP-14 items before and after treatment revealed that subjects exhibited improvement in all the domains. OHIP-14 scores did not differ significantly in terms of age, gender, and education after treatment. OHIP-14 score was considerably higher for patients with medical conditions (P = 0.007) and among complete denture wearers compared to patients with fixed prostheses (P = 0.025). Prosthetic treatment positively impacts oral health-related quality of life (OHRQoL), which improved after treatment, particularly in the social domain. There was an association between patients’ medical condition, prosthesis type, and OHIP-14 score.

Neurosurgery in Saudi Arabia: Navigating Through Future Pathways and Students' Perspectives

Neurosurgery is a surgical discipline that demands comprehensive knowledge in other specialties. It is regarded as one of the most competitive specialties. However, there is a new trend toward considering life-style friendly specialties. Therefore, this study aims to assess the neurosurgery perception and identify potential factors influencing such attitudes. An observational, survey-based study was conducted on medical students at the College of Medicine, Imam Abdulrahman bin Faisal University, Dammam, Saudi Arabia. An online-based questionnaire was administered to the participants. It consisted of two main parts: the first part collected demographic data, while the second part included 20 Likert scale-based questions. Pearson's Chi-square test was utilized, with statistical significance set at p<0.05. A total of 305 medical students from various academic years participated in the questionnaire survey, with nearly an equal gender distribution. Remarkably, a significant majority (76.72%) expressed uncertainty or disagreement regarding the adequacy of neurosurgery education during their medical studies. While a substantial portion of participants (69.5%) found neurosurgery intriguing, almost half (47.87%) indicated that they would not pursue it as their future specialty. The consideration of neurosurgery as a career path showed statistically significant differences in relation to both gender and academic year (p=0.009 and p<0.001, respectively). This study emphasizes how gender and academic year affect choosing neurosurgery as a career but notes limitations like self-reporting bias and a single-institution scope, which may affect generalizability. Future research might consider national summer training programs to engage more students in neurosurgery.

Prevalence of adult attention deficit hyperactivity disorder (ADHD) among medical students in the Eastern Province of Saudi Arabia.

To determine and compare the prevalence of attention deficit hyperactivity disorder (ADHD) symptoms among male and female medical students in the Eastern Province of Saudi Arabia and evaluate the effect of ADHD on the academic performance of the affected medical students. This cross-sectional study measured the prevalence of adult ADHD symptoms among medical students in the Eastern Province of Saudi Arabia. A total of 354 Saudi medical students from King Faisal University, Al-Ahsa, and Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia, participated in a self-reported questionnaire. The questionnaire was distributed on different social media platforms from December 2021 to April 2022. Among the study participants, 26% exhibited symptoms highly consistent with adult ADHD. Young age (<20 years, p=0.049) and non-marital status (p=0.048) were associated with a higher rate of ADHD symptoms with recorded statistical significance. Additionally, there is no significant association between grade point average and adult ADHD (p=0.560). The study demonstrated a higher prevalence of adult ADHD among medical students in the Eastern Province than the reported rates locally and globally. This could be attributed to social and cultural factors, as well as the chosen method for assessing the symptoms of Diagnostic and Statistical Manual items.

Attitude and Understanding of Artificial Intelligence Among Saudi Medical Students: An Online Cross-Sectional Study.

Artificial Intelligence is drastically used nowadays in healthcare, but little is known about the attitude and perception of medical students towards AI in Saudi Arabia. This study aimed to explore undergraduate medical student's views on AI, assessed their understanding of AI, and the level of confidence of using basic AI tools in the future. This cross-sectional study invited 303 medical undergraduate students to complete an anonymous electronic survey, which consists of questions related to attitude, understanding and confidence of using basic AI tools. We examined the statistical association between the categorical variables by using Chi-square test. The results of the study indicate that eighty-seven percent of participants believed that AI will play significant role in healthcare. Thirty-eight percent respondents reported that they have an understanding of the basic computational principle of AI. 71.29% respondents agreed that teaching in AI would be favorable for their career. More than half of the participants were confident in using basic AI tools in the future, Male students (p = 0.00), 26-30 years old participants (p = 0.03), intern students (p = 0.00), and Imam Abdulrahman Bin Faisal University medical students (p = 0.04) had positive attitude of artificial intelligence. Male participants (p = 0.02), and intern students (p = 0.00) had the highest proportion of confidence in using basic healthcare AI tool. Nearly 14% students received training on AI. Participants who received training on AI reported better understanding of AI (p = 0.03), develops positive attitude towards teaching in AI (p = 0.05), more confidence in using basic healthcare AI tools (p = 0.05). Saudi medical undergraduate students understand the significance of AI and demonstrated a positive attitude towards AI. Medical students training on AI should be expanded and improved to avoid threats for seeking jobs by adapting artificial intelligence.

Radiographic assessment of dental post and core placement at different educational levels in an undergraduate student clinic: a 4-year retrospective study.

Dental post and core is one of the common procedures performed after endodontic treatment. The aim of this study was to radiographically assess the quality of post and core procedures performed by dental students at different education levels in addition to determining the most critical errors encountered during their clinical practice. A retrospective cross-sectional study design was conducted in the College of Dentistry, Imam Abdulrahman Bin Faisal University. A total of 550 periapical radiographs (PAs) of cemented posts were retrieved from the records of patients treated by dental students. Parameters and guidelines for assessing the quality of post treatment have been determined and statistically analyzed. A P value <0.05 was considered statistically significant. The study included 502 students and most of them were females (66.5%). Data were obtained from 502 patients (62% females) with fiber posts used in 98.2% of the cases. About 50% of the posts were inserted in premolars, 62.9% in the upper arch, and 66.7% were restored with crowns as a final restoration. Regarding the quality of posts, 98.4% showed good preparation quality and 98% showed good radiographic quality. The post diameter was equal to 1/3 of the root diameter in 31.9% of the cases; post length was equal to 2/3 of root length in 5% of the cases and equal to or more than crown height in all cases (100%). Length of the remaining gutta percha (GP) was between 3-5 mm in 38.8%, and there was no gap between the post and remaining GP in 95.6% of the cases. There were no statistically significant differences between dental students at different clinical educational levels regarding the quality of post placement. The quality of post and core procedures performed by students showed acceptable radiographic quality and were within the recommended standards.

“Till we meet again!”: The Synchronous Hybrid Teaching of English in Saudi Arabia

This study explores the perceptions of Preparatory Year (PY) students and teachers at Imam Abdulrahman bin Faisal University regarding synchronous hybrid teaching. It also highlights the effectiveness of teaching English as a foreign language (EFL) within the two modes of the hybrid system (i.e., face-to-face and online). The study employed a triangulation of instruments, including a survey, an interview and three focus groups (FGs). The findings show that each mode has its characteristics. While the students viewed hybrid teaching positively in terms of its logistics, finding it convenient and time-saving. However, they believed high-quality education could be better achieved in person as they understood and enjoyed face-to-face classes more than online learning. They also preferred the online mode for receptive skills and face-to-face interaction for productive skills. On the other hand, teachers found hybrid teaching challenging regarding technical issues and managing two groups (remote and in class) simultaneously. They expressed various views regarding the preferred mode of teaching English skills; some wished to abandon hybrid classes and teach all the skills in face-to-face mode. During the pandemic, hybrid teaching may have been the best option to continue teaching English effectively. However, after the pandemic, this method should be retained as a backup plan to reach students with disabilities and enrich advanced learners of English.

Itisessential to detectBCearly usingimagingtechniquesthataccurately reflectthe final pathology, guiding suitable intervention strategies. Objectives This study aimed toevaluatetheagreementbetween radiological findings and histopathological resultsinBCcases. Methods We conducted aretrospective reviewofbreast core needle biopsies (CNBs)inwomenover a six-year period (2017-2022) at Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. The pathologicaldiagnoses were compared with thefindingsfrompreceding radiological investigations.We also compared the tumour sizes inthe resection specimenswiththeir radiologicalcounterparts. Results A total of 641 cases were includedin the study.Ultrasound (US),mammography,andmagnetic resonance imaging (MRI)yieldeddiagnostic accuracies of 85%, 77.9%, and 86.9%,respectively. MRIhadthe highest sensitivityat72.2%, while US hadthe lowestat61%. MRI provided the best agreementwiththefinalresected tumor size. By contrast,mammographytended to overestimate the size (41.9%), and US most frequently underestimated it(67.7%).The connectionbetween basal-like molecular subtypes and the Breast Imaging Reporting and Data System (BIRADS)-5 classifications wasonlystatistically significantfor MRI (p=0.04). The luminal subtypewas more likely to showspeculation in mammography.Meanwhile,BIRADS-4revealedaconsiderablenumber of benign pathologiesacrossall the threemodalities. Conclusions MRIdemonstrated thehighestaccuracy,sensitivity, specificity,andpositive predictive value (PPV) fordiagnosingandestimating the tumorsize.Mammographyoutperformed US in terms of sensitivityandyielded thehighestnegative predictive value (NPV). US, meanwhile, offered superiorspecificity, PPV,and accuracy. Therefore, combiningthese diagnostic methods could yield significant benefits.

Morphometric Parameters of the Ear and Their Sexual Dimorphism in the Eastern Province of Saudi Arabia.

Background The human ear is a distinctive facial feature, revealing valuable information about ethnicity, gender, and age. Anthropometric measures play a crucial role in fields such as forensic medicine, prosthetics, and plastic surgery. The external ear, known for its diversity in structure and individual characteristics, has become a subject of interest in various populations. This study aims to determine the mean values of morphometric measurements for both right and left ears while exploring sexual dimorphism in ear dimensions. Methodology A prospective, observational, cross-sectional study was conducted among 200 volunteers from the eastern province of Saudi Arabia, comprising 98 males and 102 females, at the Department of Anatomy, Institute of Medical Sciences, Imam Abdulrahman Bin Faisal University. Participants were randomly selected from King Fahad University Hospital workers and patients. Using a Vernier caliper and after obtaining consent, various aspects of ear morphology were measured. The study employed statistical analyses such as the volunteers' t-test, Pearson's coefficient of correlation, and linear regression equations. Results In males, the mean total height of the right and left ears was 6.054 ± 0.5394 and 6.044 ± 0.5235 cm, respectively, while for females, it was 5.489 ± 0.4481 and 5.763 ± 4.8446 cm, respectively. The mean widths, heights, and other dimensions of the ears exhibited variations between genders. Conclusions The study provides comprehensive insights into the dimensions and indices of the pinna among the population of the eastern province of Saudi Arabia. The findings confirmed the presence of sexual dimorphism in the ear measurements, consistent with observations in other ethnic groups.

Prevalence of depression among basic years medical students in Qassim University and Imam Abdulrahman Bin Faisal University

Background: Depression is one of the most prevalent psychiatric diseases, manifesting through a variety of mental and physical symptoms such as restless sleep, loss of interest, low mood, exhaustion, and attention issues. This study aims to determine the prevalence of depression among medical students at Qassim University (QU) and Imam Abdulrahman University (IAU). Methods: An online survey was used to assess the prevalence of depression among 1st, 2nd, and 3rd-year medical students at QU and IAU in Saudi Arabia. The survey included the Patient Health Questionnaire-9 (PHQ-9), a validated tool for measuring depression severity. Results: This study investigated depression risk factors among medical students in Saudi Arabia. In QU, a higher GPA (&amp;ge;4) was associated with a significantly lower likelihood of depression (84.2% less likely). In IAU, while no factors were significant at the stricter p

Predictors of procedural errors in class II resin composite restorations using bitewing radiographs

ObjectiveTo identify the potential factors that induce procedural errors during posterior proximal resin composite restorations placed by dental students. Materials and MethodsThis retrospective study evaluated 803 bitewing radiographs of posterior proximal resin composite restorations placed by dental students at Imam Abdulrahman bin Faisal University. Atypical radiographic signs of failure were screened, and different patient-, operator-, and clinical-related factors were recorded. Chi-square test was used to examine the relationship between procedural errors and recorded factors. Stepwise adjusted logistic regression model was performed to identify predictors of procedural errors. ResultsThe most observed errors were internal gaps at the bonding interface and internal voids. Molars had 0.39 the risk of internal voids (odds ratio [OR] = 0.39; confidence interval [CI] = 0.25–0.60; P = <0.0001), 0.41 the risk of sharp angle (OR = 0.41; CI = 0.24–0.68; P = <0.001), and 0.57 the risk of open contact (OR = 0.57; CI = 0.34–0.97; P = 0.04) compared to premolars. Those who were >40 years of age had 1.79 the risk of overhang compared to younger patients (OR = 1.79; CI = 1.04–3.11; P = <0.04). First molars and premolars had 0.64 the risk of overhang compared to second molars and premolars (OR = 0.64; CI = 0.41–1.00; P = 0.04). Junior students had 1.97 the risk of internal gap compared to their senior counterparts (OR = 1.97; CI = 1.20–3.21; P = 0.008). Mesial restorations had 0.38 the risk of external gap compared to mesio-occluso-distal (MOD) restorations (OR = 0.38; CI = 0.19–0.78; P = 0.003). Restorations with a margin coronal to the cemento-enamel junction (CEJ) had 0.44 the risk of external gap compared to those restorations with a margin apical to the CEJ (OR = 0.44; CI = 0.29–0.66; P = <0.0001). ConclusionOur findings suggested a higher incidence of procedural errors in restoring premolars and MOD cavity preparations. Therefore, it is crucial to enhance the comprehensiveness of laboratory training and expose students to diverse clinical scenarios and various techniques.
