Background The novel coronavirus disease (COVID-19) has affected hundreds of thousands of people across more than 200 countries. As the pandemic continues, the health agencies, worldwide, are recommending strict preventive practices to avert its transmission at community scale. We sought to predict the behavior of the Saudi population for adopting community preventive practices during the COVID-19 pandemic. Methods: An online questionnaire consisting of 22 items pertaining to the Health Belief Model constructs was used to measure the perceived susceptibility and perceived severity of contracting COVID-19, along with the perceived benefits and perceived barriers to follow the Ministry of Health’s recommendations. The outcome was assessed by their readiness to be compliant with the community protective measures. Data were analyzed using STATA at significance level of 0.05. Results: A total of 900 individuals received the online survey link, of which 688 (response rate: 76.4%) respondents consented to participate in the study. The mean age of the respondents was 31.39 (SD = 8.94). Positive associations were observed between perceived susceptibility (Beta: 0.24; p value < 0.001), perceived severity (Beta: 0.16; p value < 0.001), perceived benefits (Beta: 0.41; p value < 0.001), cue to action (Beta: 2.61; p value < 0.001) and the participation in community preventive practices during the pandemic of the COVID-19. Conclusions: Health belief model's constructs of perceived susceptibility, severity, benefits and cue to action can be adopted to help strengthen COVID-19 limiting behaviors and prevention programs which can delivered through community pharmacies in Saudi Arabia as well as around the world.

dehydrogenase (LDH), creatinine kinase (CK), total cholesterol (TCh), triglycerides (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), verylow density lipoprotein cholesterol (VLDL-C) and markers of oxidative stress parameters like lipid peroxidation (LPO), reduced glutathione (GSH), glutathione peroxidase (GPx), glutathione reductase (GR), glutathione-S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) were evaluated in the heart of type 2 diabetic rats. Results: Oral administration of WS for 5 weeks resulted in a significant (P<0.001) reduction in glucose, LDH, CK, TC, TG, LDL-C, VLDL-C levels with significant elevation of HDL-C levels. On the other hand, WS treated diabetic rats significantly ( P<0.01-P<0.001) reduced the elevated levels of LPO, increased levels of antioxidant enzymes (i.e, GSH, GPx, GR, GST, SOD and CAT). Conclusion: These findings propose the role of hyperlipidemia and cardiac oxidative stress in type 2 diabetic rats and suggested protective effect of WS in this animal model.

This study aims to detect the prevalence and antimicrobial resistance of Listeria monocytogenes and Cronobacter sakazakii in three dairy households and dried milk from different suppliers, and evaluate the antimicrobial effect of rose water, rose, and orange essential oils. In total, 360 samples were collected from cattle, the environment, and dried milk (n = 30). Antimicrobial activity was evaluated with twofold microtube dilution and the time-kill method. L. monocytogenes was identified in all households (13.3%) with a prevalence in the range of 5.8–17.5%, while C. sakazakii was identified in one household (5.3%). The former and latter pathogens were highly isolated from the feces at 20% and 2.5% and bedding at 12.5% and 1.6%, respectively. L. monocytogenes was isolated only from milk at 7.5%, but C. sakazakii was not detected in either milk or dried milk. L. monocytogenes strains were screened for virulence genes (iap, hylA, and actA). All strains were positive for the iap gene, while for hlyA and actA, the percentages were (35.4% 16.6%, respectively). L. monocytogenes strains showed high resistance against sulfamethoxazole–trimethoprim (100%), followed by gentamicin, penicillin, and imipenem (95.8%, 95.8%, and 91.6%, respectively). All C. sakazakii strains were susceptible to all tested antibiotics. The bactericidal activity of orange oil was the strongest, appeared after 1 h for both pathogens, followed by rose oil and then rose water.

Although prevalence of substandard or counterfeit drugs is a world-wide problem, poor and developing countries are affected the most. To be a quality product, drug formulation must comply with certain standards. Consequently, in this study, metformin hydrochloride (MH) tablets (500 mg) available in the Saudi Arabian market were assessed through various pharmacopeial quality control tests. Parameters including weight variation, hardness, friability, drug content, and disintegration time were evaluated. Results were within acceptable limits for all selected products (nine generic and an innovator). Fourier-transform infrared spectroscopy (FT-IR) spectra of MH for all tested products were completely superimposed with that of the pure drug, confirming the use of correct active ingredient in all tablet formulations. The products were also evaluated by comparing the dissolution profile of the generic products with the innovator brand in pH 6.8 phosphate buffer. The range of percent drug release in 30 min was 82.71-98.43%, in comparison to 91.86% for reference product, which complies with the USP-NF specification of at least 80% drug release in 30 min. The difference factor (f 1 ), similarity factor (f 2 , except product H), and dissolution efficiency revealed that the dissolution profiles of the tested products were comparable to that of the reference product. These results show that the tested generic products were biopharmaceutically similar (except product H) to the innovator formulation. Therefore, the consumer can select any one of these equivalent products as a substitute for innovator product in case of cost concern or unavailability.
