Background: The closure of educational activities in the Kingdom of Saudi Arabia due to the ongoing COVID-19 pandemic resulted in an unplanned shift from traditional learning to a setup that exclusively involves digital teaching and learning. Within this context, the present study aimed to explore undergraduate medical students' perceptions regarding the effectiveness of synchronized online learning at

A new compound, 3-O-alpha-L-arabinopyranosyl-4-hydroxybenzoic acid (13), in addition to 16 newly reported compounds: alpha-amyrin acetate (1), beta-amyrone (2), 3beta-acetoxy-20-taraxasten-22-one (3), alpha-amyrin (4), ceryl alcohol (5), stigmasterol (6), beta-sitosterol (7), 2alpha,3alpha-dihydroxy-lup-20(29)-en-28-oate (8), ursolic acid (9), beta-sitosterol-3-O-glucosoide (10), protocatechuic acid (11), betulinic acid (12), quercetin (14), quercetin-3-O-beta-D-glucoside (15), kampferol-3-O-beta-neohesperidoside (16) and rutin (17) were isolated from the stem bark and leaves of Ficus pandurata (Hance) cultivated in Egypt. Identification of these compounds has been established by physical, chemical and spectral data (UV, IR, MS, (1)H- and (13)C-NMR), as well as comparison with authentic samples.

Handwashing (HW) with water and soap is one of the cheapest and most effective ways of protecting oneself and others against the coronavirus. Here, the HW knowledge, attitudes, and practices of Saudi adults were assessed during the COVID-19 pandemic using a cross-sectional study conducted between May 8 and June 8, 2020, during a partial lockdown period. A web-based validated questionnaire was distributed through different social media platforms, and the sociodemographic characteristics of the participants, seven items related to knowledge, four items related to attitudes, and thirteen items related to the practice of HW were assessed. A total of 1323 (51% male and 49% female) adults from all regions of Saudi Arabia responded to the questionnaire. The overall mean (± SD) was 5.13 (± 1.18) for knowledge of HW and COVID-19, 2.79 (± 0.77) for attitude toward HW, and 7.8 (± 2.56) for HW practice. A multiple linear regression analysis revealed factors associated with knowledge to be age and family income. Sex, educational level, family income, and HW knowledge were associated with negative and neutral attitude, whereas age, sex, family income, and HW knowledge were associated with practice. These results suggest that HW knowledge was strongly associated with positive attitudes toward HW and correct HW practice in Saudi adults during the COVID-19 lockdown.

BackgroundCardiopulmonary resuscitation (CPR) is a lifesaving technique that is vital to deal with in many emergencies. Early interference with the cardiopulmonary resuscitation technique is really important for the survival of the patient. This study assesses the level of knowledge, attitudes, and practices regarding CPR among Qassim University students.Materials and methodsA cross-sectional study was conducted at Qassim University. The sample was university students. The colleges were chosen by a simple random technique. Data were collected using a pretested, semi-structured questionnaire for knowledge, attitudes, and practices related to CPR. The data were analyzed using Statistical Package for the Social Sciences (SPSS; IBM Corporation, Armonk, NY).ResultsThe total sample size of the participating students was 1148, of which 589 (51.3%) were female and the remaining were male (559, 48.7%). The common age was between 20 and 23 years old and most were from non-medical colleges (54.1%); the remaining (45.9%) were from medical colleges. The majority of female students (45.7%) in medical colleges knew the right location for chest compression better than the males, with a significant difference (p<0.05). No significant difference existed between males and females (p>0.05) regarding most CPR practices. On the other hand, there was a significant increase among medical students as compared to non-medical students (p<0.05) regarding most knowledge, attitudes, and practice items of CPR.ConclusionBased on our study, the knowledge, attitudes, and practices of Qassim University students toward CPR are insufficient and need to be improved. Also, medical students are better than non-medical students at CPR, so we recommend that the incorporation of a Basic Life Support (BLS) course, including CPR learning procedures in the university curriculum, with regular reassessments, would increase the knowledge and application of CPR skills among students for saving people's life.
