Exploring Saudi EFL Students’ Attitudes Towards NES and NNES Teachers’ Accents

Various studies have examined EFL students' attitudes towards accented English. However, this topic has rarely been studied in the Saudi context. The current study examined the attitudes of Saudi EFL university students towards teachers with British or American-accented English (a native speaker model) and Arabic-accented English (a nonnative speaker model) in the language classroom. Thirteen Saudi EFL students participated in this study. An online questionnaire was administered using the matched-guise technique. The results of the study showed that EFL teachers with an American accent is the most favored by their students. Nevertheless, there was little support for this finding. Another important finding is that the examined EFL students had similar positive attitudes towards both British and Arabic accented English. This similarity might suggest that having an accent as an EFL teacher might not perceived negatively as long as the teacher has the ability to deliver information properly

Prevalence and predictors of seizure in patients with Alzheimer’s disease at a tertiary care center in Riyadh, Saudi Arabia

Purpose: To assess the prevalence and predictors of seizures in patients with Alzheimer’s disease (AD) at a Saudi tertiary hospital.Methods: A retrospective, matched case-control study was conducted using the electronic medical records of patients with AD who had an unprovoked seizure, from October 2015 to May 2018.Results: Nineteen cases and 195 controls were identified. Statistically significant risk factors for an unprovoked seizure in patients diagnosed with AD were hypertension (p = 0.001), autoimmune disease, stroke and TIA (p = 0.001). The multivariate logistic regression analysis identified hypertension (OR = 2.89; p = 0.009) and autoimmune disease (OR = 19.6; p = 0.045) as predictors of unprovoked seizure in AD patients.Conclusion: The occurrence of unprovoked seizures is more likely in severe cases of AD. In addition, the risk of seizure in patients with AD increases with two co-morbid conditions, hypertension, and autoimmune disease. However, further studies are required to determine the underlying mechanism of the association between the two risk factors and AD

Internship preparedness among students in healthcare-related fields in the COVID-19 era: Exploring the attitude and knowledge in Saudi Arabia

Background: In the COVID-19 era, efforts are being made to increase awareness among students and enhance best practices to mitigate the outbreak. To that end, the overarching aims of this study were to understand students’ attitude toward and knowledge of COVID-19 and examine the predictors of their attitude toward hand hygiene.Design and Methods: This cross-sectional survey study, conducted in Saudi Arabia, enrolled interns from diverse healthcare-related fields. The questionnaire was divided into three sections: sociodemographic data, knowledge of COVID-19, and attitude toward hand hygiene. The data was expressed as median and interquartile range (IQR).Results: In all, 371 responses were analyzed. The median knowledge score was 20, which was considered good. There were no statistically significant differences across age, hospital setting, or gender. Of the 254 respondents who had attended an educational session, 167 (65%) had a good knowledge score and 83 (33%) had a moderate score, compared with only four (2%) who had a poor score. The cumulative median score of the respondents’ attitudes was 6 (IQR [2]), which reflects a suboptimal attitude—only 38 (22%) reported a good attitude. The predicted effect of knowledge on attitude (good/suboptimal) was statistically significant (p = 0.02) using univariate logistic regression.Conclusions: The results suggest a strong need to encourage the current training program that targets hand hygiene practices among students in healthcare-related fields, especially prior to the internship year

Radiographic assessment of endodontic mishaps in an undergraduate student clinic: a 2-year retrospective study

Objectives. The aim of this study was to compare the occurrence of instrumentation and obturation related endodontic procedural mishaps following the use of either, stainless steel hand or engine-driven rotary instrumentation techniques. Methods. From a computerized hospital database, a total of 730 dental patient records who had received endodontic treatment by undergraduate dental students between August 2018 to September 2020 were retrieved. The inclusion criteria were primary (non-surgical) endodontic treatment on permanent teeth with complete radiographic records. Following record screening, a final sample of n = 475 dental records were included. Radiographic records were evaluated for both instrumentation and obturation related mishaps. The data was analysed using multiple logistic regression analysis (α = 0.05). Results. Engine-driven rotary instrumentation resulted in a significant decrease in the overall occurrence of instrumentation related endodontic mishaps by 40% compared to hand instrumentation (Odds Ratio = 0.59 [0.36–0.97], p = 0.04). In particular, rotary instrumentation decreased ledge formation, perforation and obturation related mishaps, with minimal effect on the limitation of zipping. Conclusion. The use of rotary instrumentation techniques may reduce the incidence of instrumentation and obturation endodontic mishaps in the undergraduate dental clinic.Princess Nourah bint Abdulrahman University Researchers Supporting Project number (PNURSP2022R162), Princess Nourah Bint Abdulrahman University, Riyadh, Saudi Arabia

Dexamethasone versus methylprednisolone for multiple organ dysfunction in COVID-19 critically ill patients: a multicenter propensity score matching study

Abstract Background Dexamethasone usually recommended for patients with severe coronavirus disease 2019 (COVID-19) to reduce short-term mortality. However, it is uncertain if another corticosteroid, such as methylprednisolone, may be utilized to obtain better clinical outcome. This study assessed dexamethasone’s clinical and safety outcomes compared to methylprednisolone. Methods A multicenter, retrospective cohort study was conducted between March 01, 2020, and July 31, 2021. It included adult COVID-19 patients who were initiated on either dexamethasone or methylprednisolone therapy within 24 h of intensive care unit (ICU) admission. The primary outcome was the progression of multiple organ dysfunction score (MODS) on day three of ICU admission. Propensity score (PS) matching was used (1:3 ratio) based on the patient’s age and MODS within 24 h of ICU admission. Results After Propensity Score (PS) matching, 264 patients were included; 198 received dexamethasone, while 66 patients received methylprednisolone within 24 h of ICU admission. In regression analysis, patients who received methylprednisolone had a higher MODS on day three of ICU admission than those who received dexamethasone (beta coefficient: 0.17 (95% CI 0.02, 0.32), P = 0.03). Moreover, hospital-acquired infection was higher in the methylprednisolone group (OR 2.17, 95% CI 1.01, 4.66; p = 0.04). On the other hand, the 30-day and the in-hospital mortality were not statistically significant different between the two groups. Conclusion Dexamethasone showed a lower MODS on day three of ICU admission compared to methylprednisolone, with no statistically significant difference in mortality

SARS-CoV-2 vaccination modelling for safe surgery to save lives: data from an international prospective cohort study

Background: Preoperative SARS-CoV-2 vaccination could support safer elective surgery. Vaccine numbers are limited so this study aimed to inform their prioritization by modelling. Methods: The primary outcome was the number needed to vaccinate (NNV) to prevent one COVID-19-related death in 1 year. NNVs were based on postoperative SARS-CoV-2 rates and mortality in an international cohort study (surgical patients), and community SARS-CoV-2 incidence and case fatality data (general population). NNV estimates were stratified by age (18-49, 50-69, 70 or more years) and type of surgery. Best- and worst-case scenarios were used to describe uncertainty. Results: NNVs were more favourable in surgical patients than the general population. The most favourable NNVs were in patients aged 70 years or more needing cancer surgery (351; best case 196, worst case 816) or non-cancer surgery (733; best case 407, worst case 1664). Both exceeded the NNV in the general population (1840; best case 1196, worst case 3066). NNVs for surgical patients remained favourable at a range of SARS-CoV-2 incidence rates in sensitivity analysis modelling. Globally, prioritizing preoperative vaccination of patients needing elective surgery ahead of the general population could prevent an additional 58 687 (best case 115 007, worst case 20 177) COVID-19-related deaths in 1 year. Conclusion: As global roll out of SARS-CoV-2 vaccination proceeds, patients needing elective surgery should be prioritized ahead of the general population
