The impact of age, gender and fasting blood glucose on serum lipid profile at tertiary care hospital: a retrospective study.

BACKGROUND AND AIM: This relatively large retrospective study explores the impact of age, gender and fasting blood glucose level on lipid profile. It has been known that many factors could influence the lipid profile. It is crucial to investigate these relationships as dyslipidemia has been linked to many critical diseases such as cardiovascular disease.   Methods:Data of 3115 individuals were collected include the age, gender, total serum cholesterol, high-density lipoprotein (HDL), low-density lipoproteins (LDL), triglyceride (TGL) and fasting glucose levels at King Fahad Military Medical Complex's Clinical Chemistry Laboratory, Dhahran, from January 2019 to July 2019.   Results: The results shows that people who were 65 years or older had significant association with total cholesterol (p<0.001), LDL (p-value= 0.001) and triglycerides (p-value= 0.001). Regarding gender,  women, in general, are 1.2 times more likely to have hypercholesterolemia than men. Diabetes was significantly associated with all lipid profile parameters.   Conclusions: There is a variable association between lipid profile with age, gender, and fasting glucose.

Molecular epidemiology of SEN virus among blood donors and renal dialysis patients.

BACKGROUND AND PURPOSE: The SEN virus (SEN-V) is a single-stranded circular, non-enveloped DNA virus that has been linked to blood transfusion and is thought to be a major cause of post-transfusion hepatitis. The two SENV types, SENV-H and SENV-D, are non-A to E hepatitis viruses  in those who are infected. The purpose of this study is to find out how common SENV and its variations are among renal dialysis patients and healthy blood donors. METHODS: The study used a cross-sectional design, with 300 blood samples collected from KFMMC patients, 150 from healthy blood donors and 150 from renal dialysis patients, between January 2019 and January 2021. The samples were screened for the presence of SENV-D and SENV-H. using nested PCR. RESULTS: Molecular analysis of the SEN virus revealed that 9.3% of the samples (14 out of 150) tested positive for SEN virus infection in renal dialysis patients. The data from healthy donors revealed that 10% of the samples tested positive for the SEN virus (15 out of 150). CONCLUSIONS: The presence of SEN-V in healthy blood donors and renal dialysis patients demonstrates the virus's blood-borne nature and emphasizes the dangers of blood-borne transmission.

Health Sciences Students' Attitude, Perception, and Experience of Using Educational Simulation in Saudi Arabia: A Cross-Sectional Study.

Background: Simulation-based education (SBE) provides a safe, effective, and stimulating environment for training medical and healthcare students. This is especially valuable for skills that cannot be practiced on real patients due to ethical and practical reasons. We aimed to assess medical students' attitude, perception, and experience of simulation-based medical education in Saudi Arabia. Method: A validated cross-sectional survey, using the KidSIM scale, was conducted to measure the level of perception and experience of students from different health sciences specialties toward integrating simulation as an educational tool. Participants responded to questions investigated the importance of simulation, opportunities for Inter-Professional Education (IPE), communication, roles and responsibilities, and situation awareness. Only students with previous experience of SBE were considered for participation. Result: This survey was completed by 246 participants, of whom 165 (67%) were male students and 228 (93%) were aged between the range of 18-30 years old. Of the respondents, 104 (67%) were respiratory care students, 90 (37%) were anesthesia technology students, and 45 (18%) were nursing students. Most of the participants had previous experience in IPE simulation activities (84%), and more than half of the students (54%) had a grade point average (GPA) ranging between 5.00 and 4.50. Overall, students had positive attitudes toward and beliefs about SBE, with a mean score of 129.76 ± 14.27, on the KidSIM scale, out of 150. Students' GPA was significantly associated with a better perception to the relevance of simulation (p = 0.005), communication (p = 0.003), roles and responsibilities (p = 0.04), and situation awareness (p = 0.009). GPA is merely the sole predictor for positive attitude toward simulation with coefficient Beta value of 4.285 (p = 0.001). There were no significant correlations between other students' characteristic variables (gender, specialty, study year, experience in IPE, and prior critical care experience). Conclusion: We found that health sciences students' perception of SBE in Saudi Arabia is generally positive, and students' performance is a significant determinant of the positive perception.

Factors related to COVID-19 vaccine hesitancy in Saudi Arabia.

Objectives: To assess the amount of vaccine hesitancy and its determinants in relation to various demographic, social, and personal characteristics among the Saudi population. Study design: Cross-sectional study. Methods: we utilized a structured questionnaire on a five point-Likert scale that included immunization process awareness, perception towards immunization and factors leading to vaccine refusal. Results: The study included 5965 participants characterized according to various demographical factors. The participant's knowledge, perception, and the factors affecting the decision of taking the vaccine were calculated. About 40.7% had enough information about COVID-19 vaccines and were willing to take it. The participant's perception towards COVID-19 vaccines is proportional to their knowledge and varied with the personal characteristics. Factors influencing vaccine use varied also with personal characteristics. Intent to be vaccinated was higher among older age groups, advanced education, retirees, and higher income persons (P < 0.001). Moreover, the influence of heterogeneity in personal perception towards COVID-19 vaccines has been discussed. Vaccine barriers scores were significantly higher among lower educational and income levels (P = 0.004). The leader's influence on vaccine decision was high (p < 0.001). The side effects of COVID-19 vaccine is the most important barrier to vaccine acceptance. Knowledge and perception score were consistently and significantly higher among the group who received their information from official websites, followed by those who had used both websites and social media (p < 0.001). Conclusion: Additional approaches will be needed to effectively meet the needs of the hesitant population, particularly the safety and efficacy concerns, the speed of vaccine development, and the distrust in government and health organizations.
