Objectives: We aimed to describe the epidemiological and clinical characteristics of patients with COVID-19 in Saudi Arabia in various severity groups. Methods: Data for 485 patients were extracted from the medical records from the infectious disease center of Prince Mohammed bin Abdul Aziz Hospital in Riyadh. Patients' basic information, laboratory test results, signs and symptoms, medication prescribed, other comorbidities, and outcome data were collected and analyzed. Descriptive data were reported to examine the distribution of study variables between the severe and not severe groups. Results: Of 458 included patients, 411 (89.7%) were classified as not severe, 47 (10.3%) as severe. Most (59.1%) patients were aged between 20 and 39 years. Patients with severe conditions were non-Saudi, with a chronic condition history, and tended to have more chronic conditions compared with those without severe disease. Diabetes, hypertension, and thyroid disease were significantly higher in patients with severe disease. Death was reported in only 4.26% of severe patients. Only 16 (34.04%) patients remained in the hospital in the severe group. Conclusions: Severe cases were more likely to have more comorbidities, diabetes, hypertension, and thyroid disorders were most common compared with non-severe cases.

Objective: We aimed to evaluate the impact of the COVID-19 pandemic on the knowledge and attitudes of patients among the Saudi population toward participating in clinical trials. Methods: We conducted a descriptive, cross-sectional analysis using self-administered questionnaires for patients who attended the outpatient clinics at King Fahad Medical City and King Saud University Medical City in Riyadh, Saudi Arabia. The questionnaires included general questions about sociodemographic information, patient knowledge about clinical trials, and patient attitudes toward clinical trial participation. We used descriptive analysis to evaluate the impact of COVID-19 on patient knowledge and attitudes about clinical trials. Results: From November 2019 to October 2020, 822 responses were collected from participants in two medical cities and included in the analysis. Most of the study participants (81%) were younger than age 42 years. Our findings showed no difference between participants who participated in clinical trials before versus during the COVID-19 pandemic (P = 0.129). Conclusion:The Saudi population knows about clinical trials, but they lack knowledge about the role of the ethics committee and about informed consent. Also, most of them do not have the experience of participating in a clinical trial. Still, they have moderately positive attitudes toward clinical trials.

Background Despite the negative effects of tobacco use, Saudi Arabia is one of the leading causes of death globally. In Saudi Arabia, 17.1% of both sexes and 3.0% of females aged 15 or older smoke. One common way to consume tobacco is through a shisha (waterpipe). This study aims to measure the knowledge of the negative health effects and attitudes toward shisha use among health college students at Princess Nourah University (PNU) in Riyadh, Saudi Arabia. Method A descriptive, cross-sectional study was conducted at PNU’s health colleges, with the 525 student participants selected evenly from each college by using cluster sampling into five health colleges(College of Health and Rehabilitation Sciences, Nursing, Dentistry, Medicine and Pharmacy), data was collected by a pretested, structured questionnaire and was coded, entered and analyzed by Statistical Package for the Social Sciences (SPSS) v.20. Results 15.4% is the percentage for who had a history of smoked shisha. The percentage of current smokers was 4.19%. There was no association between the knowledge and shisha smoking practice ( P = .603). Conclusion In conclusion, the percentage of shisha smoking was high, in spite of having a high level of knowledge. Also, the knowledge toward shisha smoking and shisha practice was not associated. In contrast to a study conducted in USA which showed a slight association between the knowledge and smoking practice. (44)
