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.

Objective To assess the efficacy of Favipiravir compared to the standard therapy in treating patients with severe COVID-19 infection. Methods This is a retrospective cohort of patients with COVID-19 pneumonia who were treated with favipiravir, versus comparison group that received the standard of care. Results A total of 226 patients were included; 110 patients received favipiravir and 116 patients received standard of care. Patients who received favipiravir had longer time to recovery (14.2 ± 8.8 versus 12.8 ± 5.2, p = 0.17 ). Favipiravir was associated with an improved early day 14 mortality (4 [3.6%] versus 11 [9.5%]), p = 0.008), but was associated with a higher day 28 mortality (26 [23.6%] versus 11 [9.5%], p = 0.02). The overall mortality was higher in the favipiravir versus the standard of care group but difference was not statistically significant (33 [30.0%] versus 24 [20.7%], p = 0.10). Conclusion The addition of favipiravir to standard of care was not associated with any improvement in clinical outcomes or mortality. Larger randomized controlled clinical trials are needed to further assess the efficacy of favipiravir.

Background: While teachers have an abundant responsibility for teaching and guiding children in their academic and overall growth, previous studies have found out that the prevalence of first aid training among teachers is still low. Even though teachers act as the first line of defense in any health emergency. The present study aims at investigating the prevalence of knowledge among teachers on how to handle first aid procedures for basic and usual accidents and chronic diseases such as diabetes and epilepsy. Methodology: Quantitative observational cross-sectional study was carried out targeting the primary schools at Unaizah city, Qassim region, Saudi Arabia. The sample included exclusively teachers enrolled in a systematic approach. A total of 315 subjects participated in the study. Results: Majority of the research participants were aged between 26 years and 50 years 291 (93.9%), with only 2.6% being aged 50 years or more. Most of the participants had bachelor degree as the highest education level 239 (77.3%), while there was only one participant with a Ph.D. While 44.2% of the teachers knew first aid education, 22.3% of the participants could confidently carry out first aid procedures. Three-quarters of the participants did know what to do after a pupil faints, while 47.7% of the teachers did know what to do in the event bleeding. Conclusions: Knowledge and education of what to do in an emergency that requires first aid appears to be not a problem in the primary schools surrounding Unaizah city, Qassim region, Saudi Arabia. However, the present study still warrants practical training for the teachers on first aid procedures

A total of 420 day old chicks were divided into seven groups (5 replicates of 12 chicks/group) fed isoproteic and isoenergetic diets. The control group was fed diets containing 0.50%, 0.45% and 0.40% of non-phytic phosphorous (nPP) in starter (1–35), grower (37–56) and finisher (57–64 d) periods, respectively. The three intermediate nPP (IntnPP) groups were fed diets with 0.40%, 0.35% and 0.30% nPP according to the growth period and were submitted to three dietary treatments: unsupplemented; supplemented with 500 FTU/kg diet of an Aspergillus niger phytase (IntnPP_fp) and supplemented with 500 FTU/kg diet of an Escherichia coli phytase (IntnPP_bp). The three low nPP groups fed diets contained 0.30%, 0.25% and 0.20% nPP and were submitted to the same dietary treatments than IntnPP to obtain LnPP, LnPP_fp and LnPP_bp groups. IntnPP and LnPP groups had lower body weight gain and feed, crude protein (CP) and metabolizable energy (ME) intake (p < 0.05) than the control. Feed conversion ratio of IntnPP was more favorable (p < 0.01) than the LnPP group. CP and ME conversion ratios worsened (p < 0.01) in IntnPP and LnPP groups in comparison to the control. The nPP conversion ratio improved (p < 0.01) from the control to the LnPP group. Fungal phytase reduced (p < 0.05) feed, CP, ME and nPP intake than the bacterial one. IntnPP and LnPP diets had a lower digestibility of CP (p < 0.01) and CF (p = 0.01) than the control. IntnPP and LnPP groups showed a higher (p < 0.05) economic efficiency than the control. Blood total protein was the lowest (p < 0.05) in the LnPP group, the control group showed the lowest (p < 0.05) level of albumin and IntnPP group had the lowest (p < 0.01) globulin level. The use of bacterial phytase increased (p < 0.01) total protein and globulin and decreased (p < 0.05) the plasma cholesterol in comparison to fungal phytase. Decreasing nPP levels in colored slow-growing broilers diet negatively affects growth performance and the use of phytase can partly alleviate these negative effects, but the efficiency of different enzyme sources (bacterial or fungal) was tied to the dietary nPP levels.

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.
