This study was aimed to assess the genotoxicity of brown shammah (BS), a local form of smokeless tobacco, popular in Middle East countries including Yemen, Saudi Arabia and Sudan. The genotoxicity was explored using in vivo chromosomal aberration (CA), micronucleus (MN) and sperm abnormality (SA) assays. In addition, oxidative stress was also determined using various hepatic markers. Swiss albino mice were selected for the study, which were divided in to 5 groups of six animals each. They include, negative control (NC, received only vehicle) as well as positive control group (PC, received vehicle for 2 weeks followed by administration of cyclophosphamide, CP). Depending upon their dose, three BS treated animal groups were BS-100, 300 and 900 mg/kg. Doses of BS were obtained by suspending BS in 0.5% CMC (carboxy methyl cellulose) and orally administered once a day for 2 weeks. Significant augmentation of the average percentage of aberrant metaphase (AM), CA per cells and suppressed mitotic activity was observed on post administration of BS. In addition, BS increased the occurrence of MNPCEs (micronucleated polychromatic erythrocytes) formation, induced cytotoxicity and increased percentage of abnormal sperms as compared to NC. Moreover, BS also induced oxidative stress as the activities of hepatic superoxide dismutase (SOD) and glutathione (GSH) were reduced and malondialdehyde (MDA) content were increased by BS. Cyclophosphamide was utilized as clastogen, showed anticipated positive results and confirmed the sensitivity of test system. Therefore, it may be deduced from the study that the BS possesses genotoxic effects on mice bone marrow and germ cells in vivo. © 2020 The Author(s).Objectives This study aimed to explore the cardiologist adherence with ACC/AHA guidelines on discharge medications for patients admitted with acute coronary syndrome (ACS), assess the predictors of cardiologist non-adherence and measure the impact of pharmacist intervention on improving guideline adherence. Methods The study included two consecutive phases observation and intervention. selleck kinase inhibitor It was carried out at Al-Najaf Center for Cardiac Surgery and Catheterization, Iraq, from August through December 2018. In the observation phase, medical records were reviewed retrospectively in order to assess the adherence to guideline. The intervention phase was performed prospectively by the clinical pharmacist, who conducted interventions including auditing, feedback and discussion with every prescriber. The reference of the recommendations was the guideline of American Heart Association/American College of Cardiology guideline (AHA/ACC). The primary outcome was the proportion of patients discharged with optimal treatment.tion). Conclusion This study showed that pharmacist intervention had a considerable positive impact on the cardiologist prescribing pattern of the essential discharge medications for patients with ACS which could improve patient clinical outcomes. © 2020 Published by Elsevier B.V. on behalf of King Saud University.Multidrug resistance (MDR) is the most common problem of inadequate therapeutic response in tumor cells. Many trials has been developed to overcome drug efflux by P-glycoprotein (P-gp). For instance, co-administration of a number of drugs called chemosensitizers or MDR modulators with a chemotherapeutic agent to inhibit drug efflux. But for optimal synergy, the drug and inhibitor combination may need to be temporally colocalized in the tumor cells. In this study, we encapsulated the Ver and Dox in PLGA nanoparticles to inhibit the P-gp drug efflux in breast cancer. Moreover, the effect of either Dox solution (DoxS), Dox nanoparticles (DoxNP), DoxS + VerS, DoxNP + VerS, DoxNP + VerNP or Dox-VerNP was evaluated. It was found that co administration of DoxNP with VerNP (70.76%) showed similar cellular uptake of Dox to Dox/Ver combination solution (70.62%). However it is observed that DoxNP + VerNP has the highest apoptotic activity (early apoptotic 13.52 ± 0.06%, late apoptotic 53.94 ± 0.15%) on human breast adenocarcinoma (MCF 7) cells. Hence, it is suggested that DoxNP + VerNP is a promising administration for tumor therapy. © 2020 Published by Elsevier B.V. on behalf of King Saud University.Objective To assess the safety and effectiveness of dalbavancin compared to standard of care (SOC) in the treatment of osteomyelitis in adults. Method A retrospective cohort study of patients with osteomyelitis due to S. aureus treated with dalbavancin was conducted. Patients who received at least 2 doses of dalbavancin for the treatment of osteomyelitis between January 1, 2015 to January 31, 2018 in a single center in Texas, USA were identified and matched in 11 ratio with controls who received SOC. The primary efficacy outcome was the clinical success at the end of treatment. Secondary efficacy outcome was the clinical success continued for at least 3 months after the completion of the antimicrobial therapy. Results During study period, 21 patients received dalbavancin for the treatment of osteomyelitis; however, only 11 patients were eligible for inclusion and matched to 11 others who received SOC. Primary outcome was achieved in all 11 patients who received dalbavancin and all those patients subsequently attained the secondary outcome. In SOC group, primary outcome occurred in 82% (9/11) of patients in which 8 out of 9 patients subsequently achieved the secondary outcome. No adverse reaction noted in either group. Conclusion Dalbavancin appears to be safe and effective for the management of osteomyelitis in adults. Further studies are needed to confirm these findings. © 2020 The Authors.Background In addition to diet restriction and physical activity, diabetes mellitus is managed by the chronic use of medications that require appropriate storage conditions to maintain their stability and effectiveness. However, there is a lack of information regarding patients' knowledge of medication storage and practices in Saudi Arabia. Therefore, the objective of this study was to determine the diabetics' knowledge about medication storage requirements and to evaluate the impact of antidiabetic medications storage on the blood glucose levels. Methods This study was a cross-sectional in the form of an interviewer-guided interview using a close-ended questions. The study was conducted among patients diagnosed with diabetes at diabetic clinics of public hospitals and other diabetic specialized clinics in Hail region of Saudi Arabia, over a period of four months between January to April 2019. Results A total of 501 completed questionnaires were returned. Of the respondents, 51.5% were males and 48.5% were females.
