Prospective Matched Case-Control Study of Over-Early P100 Wave Latency in Migraine with Aura.

A sizable portion of the world's population suffers from migraines with aura. The purpose of this research is to describe the findings of a case-control study that was carried out to gain a better understanding of how migraine with aura manifests. The research looked at the P100 delay of the visual-evoked potential in both eyes of 92 healthy people and 44 patients who suffered from migraines with visual aura. All of the participants in the study were recruited from King Fahad University Hospital in Saudi Arabia. Both sets of people had the same ancestry and originated from the same location. Patients who suffered from migraines with aura exhibited a significantly shorter P100 delay in both eyes compared to healthy controls (p = 0.001), which is evidence that their early visual processing was distinct. In order to arrive at these findings, we compared people who suffer from migraines with aura to people who do not suffer from migraines and used them as subjects. These findings contribute to the ongoing attempts to bring the disease under control and provide vitally significant new information regarding the functioning of headaches with auras. The primary focus of study in the future should be on determining the nature of the connection between issues with early visual processing and headaches with aura.

Neuroprotective effect of ranolazine improves behavioral discrepancies in a rat model of scopolamine-induced dementia.

Background: Ranolazine (Rn), an antianginal agent, acts in the central nervous system and has been used as a potential treatment agent for pain and epileptic disorders. Alzheimer's disease (AD) is one of the most prevalent neurodegenerative diseases and the leading factor in dementia in the elderly. Aim: We examined the impact of Rn on scopolamine (Sco)-induced dementia in rats. Methods: Thirty-two albino male rats were divided into four groups: control, Rn, Sco, and Rn + Sco. Results: A significant decrease in the escape latency in the Morris water maze test after pre-treatment with Rn explained better learning and memory in rats. Additionally, Rn significantly upregulated the activities of the antioxidant enzymes in the treated group compared to the Sco group but substantially reduced acetylcholinesterase activity levels in the hippocampus. Moreover, Rn dramatically reduced interleukin-1 ß (IL-1ß) and IL-6 and upregulated the gene expression of brain-derived neurotrophic factor (BDNF). Furthermore, in the Sco group, the hippocampal tissue's immunohistochemical reaction of Tau and glial factor activating protein (GFAP) was significantly increased in addition to the upregulation of the Caspase-3 gene expression, which was markedly improved by pre-treatment with Rn. The majority of pyramidal neurons had large vesicular nuclei with prominent nucleoli and appeared to be more or less normal, reflecting the all-beneficial effects of Rn when the hippocampal tissue was examined under a microscope. Conclusion: Our findings indicated that Rn, through its antioxidative, anti-inflammatory, and anti-apoptotic effects, as well as the control of the expression of GFAP, BDNF, and Tau proteins, has a novel neuroprotective impact against scopolamine-induced dementia in rats.

Assessment of dietary magnesium intake in the Eastern Province of Saudi Arabia.

Magnesium is an essential element and the most abundant intracellular cation after potassium. This cross-sectional study assessed the average dietary magnesium intake among residents of the Eastern Province of Saudi Arabia. Data was collected using a self-reported validated electronic questionnaire between April 2022 and July 2023. The first part of the survey included demographic data, and the second section comprised 33 items, including a semi-quantitative tool specifically designed to evaluate magnesium intake over the last three months. We included 1065 participants, out of whom 61.1% were women. The predominant age group was 19 - 26 years (56.9%), and most participants (83.3%) reported no comorbidities. The majority (48.5%) had normal weight, 246 (23%) were overweight, and 193 (18.1%) were obese. Most participants had low dietary magnesium intake, ranging from one to five times monthly. There was a positive correlation between age and dietary magnesium consumption. The study highlights a concerning trend of low magnesium intake, representing a risk for various chronic diseases. This trend could be linked to increased consumption of typical diets low in magnesium, such as those high in refined sugars, flour, and processed foods, prevalent among the younger Saudi population.

Impact of smoking intensities on sleep quality in young Saudi males: a comparative study.

This study aimed to compare various components of sleep quality between cigarette smokers of various intensities and non-smokers in young Saudi males. In total, 73 healthy male participants (31 smokers and 42 non-smokers) aged 17-33 years were recruited over three months (August 2018 to October 2018). All participants completed the Pittsburgh Sleep Quality Index (PSQI) questionnaire. The smokers were then divided into three groups, according to their Smoking Index* (SI) (Cigarettes Per Day (CPD) X Years of Tobacco Use), into mild, moderate, and heavy smokers. The PSQI was significantly higher in heavy smokers than in mild smokers (P=0.022) or non-smokers (p=0.013). A significant positive correlation was observed between the PSQI and the smoking index (p=0.005). Sleep duration was significantly longer in heavy smokers compared to mild (p=0.032) and nonsmokers (p=0.047). Sleep disturbance was significantly higher in moderate than nonsmokers (p=0.035) and moderate than mild smokers (p=0.028). Sleep latency was significantly longer in heavy than nonsmokers (p=0.011). Daytime dysfunction was significantly higher in moderate than mild smokers (p=0.041). Habitual sleep efficiency was significantly greater in moderate than in either mild (p=0.013) or nonsmokers (p=0.021). The use of sleep medication was significantly higher in moderate than nonsmokers (p=0.041). The findings suggest that poorer sleep quality is positively associated with smoking intensity among young Saudi males. Considering the importance of sleep quality for well-being and health, these results suggest exploring how improving sleep quality could inform future smoking cessation interventions.

Association Between Time Spent on Electronic Devices and Body Mass Index in Young Adults.

Objective: To evaluate the association between time spent on electronic devices (TSED) and body mass index in young adults. Methods: This cross-sectional study was conducted from June to December 2021 on 1877 students (aged 18-22 yrs) from multiple health Colleges of Imam Abdulrahman Bin Faisal University. The main tools of the study were 1) Body mass index (BMI) and an online questionnaire. The subjects were categorized into 3 main groups based on their TSED: 1) Low TSED < 2 hours/day, 2) Medium TSED= 3 to 5 hours/day, 3) Excessive TSED ≥ 6 hours /day. Based on BMI, subjects were categorized into three main groups: Normal and underweight (BMI ≤ 24.9), overweight (BMI > 25-29.9), and obese (BMI > 30). Results: Participants' average age was 20 ± 2 years. The average BMI was 23.5 k/m2. The % of students falling into the categories of normal weight, overweight, and obesity was 69.2%, 19.05%, and 11.7% respectively. The average TSED of study participants was 8.2 ± 3.45 hrs /24 hours. 71.15% of participants indicated a TSED of ≥6 hrs/24 hours and 23.71% reported a TSED of 3-5 hrs/24 hours. Only 3.15% of participants reported TSED of ≤2 hrs/24 hours. Although a rise in the mean BMI was observed with an increase in the TSED, but this difference was not statistically significant. The pairwise wise comparison also failed to demonstrate any difference in BMI between different categories of TSED. Furthermore, no significant positive correlation was found between increased BMI and excessive TSED (P = 0.37). Conclusion: A high percentage of young adults (31.2%) were overweight or obese, but excessive TSED was not significantly associated with increased BMI in this study population. Further studies are recommended to identify the effects of other factors in causing increased BMI in young adults.

Association of Sleep, Body Weight and Physical Exercise with Plasma BDNF Levels in Healthy Male Saudi Smokers.

Introduction: Brain-derived neurotrophic factor (BDNF) has been shown to impact neural function and development. The BDNF plasma levels may be affected by a smoker's behavior. Thus, the aim of this study was to investigate the association between sleep, body weight and physical exercise with brain-derived neurotrophic factor (BDNF) in healthy male Saudi smokers. Methods: A cross-sectional study, with a convenience sample, was conducted during personal visits to the Anti-Smoking Clinic and Family and Community Medical Center of Imam Abdurrahman Bin Faisal University (IAU) in Dammam at the end of 2018. Blood samples were taken from participants to measure the BDNF plasma levels. Multiple linear regression analysis was used to examine the relationship between plasma BDNF levels and participants' background characteristics, such as smoking index, physical activity, body mass index (BMI) and Pittsburgh sleep quality index (PSQI). Results: A sample of 73 (31 smokers and 42 non-smokers) males took part in the study. The results demonstrated a significant relationship between plasma BDNF levels with physical activity, smoking age, smoking index, PSQI and BMI 25-29.9 (overweight). However, the results showed no significant relationship between plasma BDNF levels and BMI (healthy weight) and obesity. Conclusion: This study shows that physical activity and sleeping quality can provide a positive impact against smoking-associated variation of the BDNF plasma levels, which may affect the health of Saudi males. Further investigation is needed to understand what other potential background characteristics are best predictive or correlated with BDNF plasma levels.

Additionally, the application assisted students to engage with collaborative learning, maintain their wellbeing, and ensure their security. However, they also reported some drawbacks, i.e., a complex interface, information overload, and a tendency to distract them, causing time wastage. CONCLUSION: This study concludes that Telegram provides an effective mobile learning platform for medical students during the current crisis, in particular. Moreover, it offers considerably more functionalities and fewer potential drawbacks than alternative applications.

Development of an entrustable professional activities (EPAs) framework for small group facilitators through a participatory design approach.

Background: Recent reports suggest that faculty development (FD) programs need a structured framework to design training and assess improvement in teaching performance of participants. Entrustable professional activities (EPAs) can serve as a novel framework to plan and conduct structured FD programs, and to assess the proficiency of small group facilitators after training. Objective: The researchers aimed to develop an EPAs framework for small group facilitators. Design: In March 2019, three workshops were organized to develop the EPAs framework by using a participatory action design approach. An orientation workshop was conducted to train the participating students and teachers. Then, a design workshop was conducted to develop the EPA framework, where data were collected from three sources: scribe notes, audio recordings, and field charts. Thematic analysis was performed, and consensus was sought from participants on the extracted professional tasks and competencies in the consensus workshop. In the third workshop, the participants also mapped professional tasks with relevant competencies. Results: A total of 15 teachers and 15 studentsf participated in the co-design process. Through a robust thematic analysis of multisource data, 57 professional tasks and 52 competencies emerged, which were converged into 11 tasks and 17 competencies after removing duplicating and non-qualifying professional tasks and competencies. Finally, a consensus was achieved on nine tasks and 12 competencies. Conclusions: The proposed EPAs framework can serve as a road map for longitudinal training and entrustment of small group facilitators. It can also guide small group facilitators in their continuous professional development and in building their teaching portfolios.

Student Perceptions Regarding Group Learning Activities in a Hybrid Medical Curriculum.

INTRODUCTION: Problem- and team-based learning strategies have been introduced in the revised integrated curriculum of our medical college. This study aims to assess perceptions of students regarding recently introduced group learning activities into our hybrid curriculum. MATERIALS AND METHODS: This descriptive cross-sectional study has used a pre-validated questionnaire to find out the perceptions of medical students studying at College of Medicine, Imam Abdulrahman Bin Faisal University (IAU). The response of students on the questionnaire was recorded by using a 5-point Likert scale. The data was analyzed by using one-way ANOVA. Mean and standard deviation were calculated. Additionally, three open-ended questions were asked to assess the merits and demerits of these newly implemented group learning approaches. RESULTS: Out of 736 students, 190 (25.81%) completed the questionnaire. Among the 190 respondents, 64 were from second year, 65 were from third, and 61 were from fourth. Overall, the results show a positive response of students and that they favor the introduction of group learning instructional design in the hybrid curriculum. Students perceived group learning to be helpful in developing their critical thinking, socialization, motivation, and communication skills. CONCLUSION: This study concludes that group learning activities introduced in a hybrid curriculum have remained successful in promoting group dynamics and overall satisfaction of students toward group learning. However, some issues have been reported too. The views of the students recorded in this study might be helpful in evaluating the implemented hybrid curricula and in optimizing the group environment and function.
