Predictors of misconceptions, knowledge, attitudes, and practices of COVID-19 pandemic among a sample of Saudi population
This study intends to explore the predictors of misconceptions, knowledge, attitudes, and practices concerning the COVID-19 pandemic among a sample of the Saudi population and we also assessed their approaches toward its overall impact. This online cross-sectional survey was conducted at the Faculty of Medicine, Rabigh, King Abdulaziz University (KAU) in Jeddah, Saudi Arabia (SA). Participants were approached via social media (SM), and 2006 participants (953 [47.5%] females and 1053 [52.5%] males) were included in this study. SM was the leading source of information for 43.9% of the study participants. Most of the participants had various misconceptions such as “females are more vulnerable to develop this infection, rinsing the nose with saline and sipping water every 15 minutes protects against Coronavirus, flu and pneumonia vaccines protect against this virus.” About one-third of participants (31.7%) had self-reported disturbed social, mental, and psychological wellbeing due to the pandemic. Many participants became more religious during this pandemic. Two-thirds of the study participants (68.1%) had good knowledge scores. Attitudes were highly positive in 93.1%, and practice scores were adequate in 97.7% of the participants. Participants’ educational status was a predictor of high knowledge scores. Male gender and divorced status were predictors of low practice scores, and aged 51–61 years, private-sector jobs, and student status were predictors of high practice scores. Being Saudi was a predictor of a positive attitude, while the male gender and divorced status were predictors of a negative attitude. Higher education was a predictor of good concepts, while the older age and businessmen were predictors of misconceptions. Overall, our study participants had good knowledge, positive attitudes, and good practices, but several myths were also prevalent. Being a PhD and a Saudi national predicted high knowledge scores and positive attitudes, respectively. A higher education level was a predictor of good concepts, and students, private-sector jobs, and aged 51–61 years were predictors of high practice scores. Study participants had good understanding of the effects of this pandemic.
The Use of Artificial Intelligence in Medical Imaging: A Nationwide Pilot Survey of Trainees in Saudi Arabia
Artificial intelligence is dramatically transforming medical imaging. In Saudi Arabia, there are a lack of studies assessing the level of artificial intelligence use and reliably determining the perceived impact of artificial intelligence on the radiology workflow and the profession. We assessed the levels of artificial intelligence use among radiology trainees and correlated the perceived impact of artificial intelligence on the workflow and profession with the behavioral intention to use artificial intelligence. This cross-sectional study enrolled radiology trainees from Saudi Arabia, and a 5-part-structured questionnaire was disseminated. The items concerning the perceived impact of artificial intelligence on the radiology workflow conformed to the six-step standard workflow in radiology, which includes ordering and scheduling, protocoling and acquisition, image interpretation, reporting, communication, and billing. We included 98 participants. Few used artificial intelligence in routine practice (7%). The perceived impact of artificial intelligence on the radiology workflow was at a considerable level in all radiology workflow steps (range, 3.64–3.97 out of 5). Behavioral intention to use artificial intelligence was linearly correlated with the perceptions of its impact on the radiology workflow and on the profession (p < 0.001). Artificial intelligence is used at a low level in radiology. The perceived impact of artificial intelligence on radiology workflow and the profession is correlated to an increase in behavioral intention to use artificial intelligence. Thus, increasing awareness about the positive impact of artificial intelligence can improve its adoption.
Efficacy and safety of paranasal sinus balloon catheter dilation in pediatric chronic rhinosinusitis: a systematic review
Objective Chronic rhinosinusitis (CRS) negatively affects quality of life (QoL), and balloon catheter sinuplasty (BCS) has shown good outcomes in adult patients. However, there has not been much research on the effects of BCS on pediatric patients. The objective of this review is to systematically assess the literature for studies demonstrating the effectiveness and safety of BCS in pediatric CRS patients. Data sources PubMed, Embase and Cochrane Library. Study selection We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis recommendations (PRISMA) to conduct our study. Observational- and interventional-based studies reporting efficacy and/or side effects of BCS among pediatric populations were included. Efficacy was evaluated by clinically reliable measures including Sino-Nasal 5 (SN-5) QoL scale. Antibiotic usage and revision surgery were also evaluated. Data extraction Articles were screened, and data were obtained. Study design, sample size and demographics, treated sinuses, criteria of inclusion, adjunct procedure(s), follow-up time, and outcomes measured were reported. Main findings Out of 112 articles identified, 10 articles were included: two interventional controlled trials and eight observational studies. All studies evaluating QoL by SN-5 showed a remarkable reduction in SN-5 score postoperatively. Improvement in the computed tomography (CT) and endoscopic findings for up to 1 year after operation was reported. Furthermore, the majority of patinets treated with BCS did not recieve any course of sinusitis-indicated antibiotics during long-term follow-up, and they had low surgical revision rates. Minor side effects were reported, most commonly synechia. Conclusion Available evidence suggests that BCS is safe and effective for the treatment of CRS in pediatric patients. Future randomized controlled studies with large sample size are warranted. Such studies can further determine the efficacy of BCS in managing children with CRS.
Academic and non-academic life stressors and their impact on psychological wellbeing of medical students Running title: Life stressors among medical students
Objectives: Among medical students, depression, anxiety, and stress (DAS) are key public wellbeing challenges that require epidemiological research. We aimed to evaluate potential sources of these psychological disturbances and assess the contribution of academic and non-academic life stressors in psychological morbidity among medical students. Methods: This exploratory questionnaire-based survey was conducted in a Saudi Arabian public sector medical college. A total of 231 medical students were enrolled and completed the depression, anxiety, and stress scale-21 (DASS-21) questionnaire. Results: More than half of the medical students, 129 (55.8%), had depression, 106 (45.9%) students had anxiety, and 87 (37.7%) students had stress. Academic achievement was the largest explanatory factor for depression and stress, whereas bodily appearance constituted the largest explanatory factor of anxiety among the study sample. Academic and non-academic stressors score was significantly associated with depression (adjusted Odds Ratio, aOR = 1.13, 95% CI 1.07–1.19), anxiety (aOR = 1.07, 95% CI 1.03–1.12), and stress (aOR = 1.12, 95% CI 1.08–1.17). Conclusions: Medical students have a high incidence of negative emotional states. These negative psychological states were explained by academic achievement and bodily appearance. The studied stressors influenced medical students' psychological wellbeing.
Depression and Anxiety Among Medical Students: A Brief Overview
Depression and anxiety are highly prevalent conditions worldwide. This article reviews the extent of depression and anxiety among medical students and elucidates associated potential risk factors. In comparison to other countries, students from Middle East countries have a higher prevalence of depression. Females suffer from these conditions more commonly than males. Factors associated with these morbidities can be divided into academic and non-academic factors. There is an inconclusiveness of whether medical students experience these symptoms more commonly than their counterparts. The present review provided a cross-sectional picture of the students' psychological well-being, which is crucial to formulate a health policy for preventive and therapeutic purposes.
Comparison of two approaches to lateral nasal osteotomy in Saudi patients
Nasal deformity is an abnormality in the appearance of the nose due to either congenital defect or trauma. In traumatic cases, patients often present with combined functional and cosmetic complaints. Therefore, otolaryngologists take into account both breathing and aesthetic nasal issues. To evaluate the changes in the nasal dorsum and base; compare breathing and aesthetic satisfaction scores between two approaches to lateral nasal osteotomy: low-to-low and low-to-high. Comparative observational; data gathered retrospectively and prospectively. Head and Neck and Skull Base Center, King Abdullah Medical City, Makkah, Saudi Arabia. Patients who received hump reduction rhinoplasty from 2013 to 2016 met the inclusion criteria. The differences in dorsal (DW) and ventral (VW) widths with a fixed interpupillary distance (IPD). Satisfaction scores for both cosmetic perspective and breathing functionality. We included 46 patients; 28 patients underwent low-to-low osteotomy and 18 patients underwent low-to-high osteotomy. With both approaches, there were statistically decreases from preoperative to postoperative ratios of VW/IPD and DW/IPD. However, differences in DW/IPD ratio and VW/IPD ratio (pre- versus post-op) were significantly higher in the low-to-low group (P < .0001). All showed breathing satisfaction postoperatively regardless of the operative approach. Patients with a low satisfaction level for aesthetic sensibility (neutral and dissatisfied) underwent low-to-high osteotomy. Both types of osteotomy showed a satisfactory outcome in both objective and subjective measures. However, low-to-low osteotomy was superior in pre- to post-operative differences in DW/IPD and VW/IPD ratios. Sampling was by convenience. The study was conducted in a single tertiary center and was a small sample.

Survival, mortality, and related comorbidities among COVID-19 patients in Saudi Arabia
Objectives: To assess the survival of COVID-19 patients in Saudi Arabia and to investigate possible mortality predictors. Methods: This is a retrospective cohort study involving 248 patients with severe acute respiratory syndrome coronavirus-2 who were admitted to the primary COVID-19 referral hospital in Jeddah between March and June of 2020. Socio-demographic characteristics, comorbidities, laboratory investigations, management protocols, complications, treatment options, and mortality data were extracted from electronic medical records. The time analysis began at the first signs of illness thorough discharge or death. Results: Our study showed that in-hospital complications including heart failure followed by acute renal failure had the largest effect size on mortality (p<0.001). Elderly patients and those with comorbid asthma had a higher risk of death. Non-survivors presented more commonly with shortness of breath and fever than survivors. High D-Dimer level was a marginally significant indicator of mortality in the studied population (p=0.05). We did not find a significant benefit in relation to any treatment option. Conclusion: Age, asthma, some in-hospital complications are important survival indicators in hospitalized COVID-19 patients. The controllable co- factors should be monitored and managed by healthcare workers to reduce mortality rates in those hospitalized with COVID-19.

Systematic review and pooled analysis of randomized controlled trials in countries of the Gulf Cooperation Council (GCC)
Objectives: To describe variations in characteristics of randomized controlled trials conducted in the Gulf Cooperation Council (GCC) countries, and critically appraising the quality of design, conduct and analysis of the trials. Methods: We carried out a systematically comprehensive electronic search of articles published between 1990 and 2018 and indexed in several databases: i) MEDLINE/ PubMed, ii) EMBASE, iii) Cochrane Central Register of Controlled Trials (CENTRAL), iv) ClinicalTrials.gov, and v) World Health Organization International Clinical Trials Registry Platform. We summarized the overall risk of bias present in all analyzed studies using the Cochrane Collaboration risk of bias tool (CCRBT). Results: A remarkable shift in numbers of publications from 2006 onwards was found. The largest number of publications were from Saudi Arabia and consisted of hospitals/clinics based studies. Lack of randomization was found in the majority of reports, and nearly three-fourth of the studies involved the use of intention-to-treat (ITT) principle. However, the proportion of adequately generated random sequence methods has increased yearly, and this increase accounted for a relatively large proportion over the latter half of the studied period (p<0.001), in contrast to the proportion of allocation concealment and blinding. Journal impact factor was significantly correlated with the quality of random sequence generation (r=0.145; p=0.014). Conclusion: The randomization methods have gained more attention over the last 3 decades. Secondly, Journal impact factor can serve as an indicator of randomization quality. To mitigate the large rate of overall high risk of bias in GCC studies, high-quality trials must be considered by ensuring adequate allocation concealment and blinding methods.
