Teaching medical students hematopathology: a randomized crossover study comparing direct inspection by light microscope versus projected images.

Background: Students' ability to diagnose various blood disorders could be substantially improved by continuously reviewing approaches toward teaching hematology. This study aims to compare the effectiveness of light microscopes and projected images on students' learning and determine medical students' perception of these teaching methods. Methods: A randomized trial was conducted using a crossover design. Two groups, each with 30 students, were subjected to teaching methods based on light microscopes and projected images alternatively. Results: No differences were found in the two study groups' baseline characteristics, such as median age, sex, and prior academic performance, as well as in the pre-test scores. Post-test scores were significantly higher among students subjected to the projection method than in the control group (Mean ± SD = 9.8 ± 1.7 vs. 5.1 ± 1.3, p < 0.001). In the post-cross-over assessment, 85% (n = 51) of students reported their satisfaction for the projected images, and 78% (n = 47) of students were willing to be taught by projection. Students perceived that the projection method facilitated participation and better involvement in discussions, improved learning, provided greater motivation, and eventually increased comprehension and efficiency. Conclusion: The projection-based teaching method is more effective in improving knowledge and achieving intended learning outcomes. Students tend to prefer the projection method over the laboratory-based method and perceive it as an effective method to enhance their learning of hematology.

Knowledge and attitude of pregnant women in the Kingdom of Saudi Arabia toward Noninvasive prenatal testing: A single center study.

BACKGROUND: Noninvasive prenatal testing (NIPT) is a screening tool for chromosomal aneuploidies. Prior knowledge of NIPT is an inherent factor in the decision-making process. We assessed the knowledge and attitude of pregnant women related to prenatal testing with a particular focus on NIPT. METHODS: A prospective cross-sectional study, using a culturally validated questionnaire, was conducted with 342 pregnant women of whom 74.9% consented for prenatal screening. Mean age and gestational weeks ± standard deviation was 31 ± 5 and 26 ± 11, respectively. RESULTS: A positive/very positive attitude was observed to ultrasound, followed by FCT, NIPT, and lastly to CVS. More than half of the participants (56.1%) had no previous knowledge of NIPT. A reaching significance association was detected between education and knowledge of NIPT. Significant association was detected between risk for aneuploidy and knowledge of NIPT. The majority (74%) indicated their willingness to perform the test. The effect and value of society on the pregnant women to make a decision regarding NIPT was negligible. CONCLUSION: The pregnant women in the current study displayed a lack of knowledge and awareness regarding prenatal screening, particularly the NIPT. We recommend that pregnant women receive adequate counseling regarding prenatal screening to increase their awareness and knowledge of prenatal testing, including NIPT.

Frequency and Risk Factors of Diabetic Ketoacidosis in a Specialized Children's Hospital, Riyadh: A Cross-sectional Study.

Objectives: Diabetic ketoacidosis (DKA) is a life-threatening complication and a leading cause of hospitalization in patients with type 1 diabetes mellitus (T1DM). We aimed to assess the risk factors of admissions of children with DKA in a specialized children's hospital to reduce morbidity and inform appropriate prevention and intervention strategies. Methods: We conducted a retrospective review of all DKA admissions at King Abdullah Specialized Children's Hospital, Riyadh (March 2015-December 2017). Data were gathered from newly diagnosed patients with T1DM and known patients ≤ 14 years old with DKA criteria. The main variables were frequency, precipitating factors, and other characteristics of DKA admissions in both groups. Results: A total of 116/562 patients with T1DM (mean age 8.9±3.0 years) had 146 DKA episodes, of which 42/116 (36.2%) were newly diagnosed. The frequency of DKA admissions were 146/562 (26.0%), of which 42/141 (29.8%) were newly diagnosed versus 104/421 (24.7%) known T1DM patients. The majority were 10-14 years old (p ≤ 0.001), and 77.8% were females. Missing insulin was the main cause of DKA (p = 0.001) among known patients with T1DM. Recurrent episodes (n = 30/146, 20.5%) occurred in 15/116 patients and were more common in children ≥ 10 years of age (p = 0.024). The mean length of stay was 2.6±2.0 days and increased with DKA severity (p = 0.008). Conclusions: Most DKA episodes were in patients with known T1DM and missing insulin was the leading cause of DKA. In addition to awareness campaigns to prevent DKA as an initial presentation, intervention strategies should also target high-risk groups of known patients of T1DM such as adolescents and patients with recurrent episodes.

Factors and Determinants of Choosing Pathology as a Future Career: Results From a Multi-Institution Study.

Background Globally, less than 10% of graduating medical students select pathology as a future career. Many factors were reported from different settings to influence the choice of pathology. The aim of this study was to investigate the factors that determine medical students' preferences in choosing pathology as a future career. Methods This cross-sectional study surveyed students from three governmental medical schools in Riyadh, Saudi Arabia. A self-administered questionnaire that contained demographic questions and items that addressed perceived factors that affect the choice of pathology was distributed to medical students. Collected data were analyzed using Statistical Product and Service Solutions (SPSS) Statistics for Windows, Version 25.0 (Armonk, NY: IBM Corp). A chi-square test was used to determine the association between independent variables and interest in pathology. Results Out of the 400 questionnaires distributed, 338 students completed the survey with a response rate of 84.5%. Overall, surgery (24%) and internal medicine (20%) were the most favored, specialties with only 5% of the students selecting pathology as their first choice. Patient-doctor interaction (72.2%) was perceived as the most important factor in not choosing pathology as a future career. Taking an elective course, younger age groups, and year in medical school were all significantly associated (p<0.001) with an interest in pathology. Conclusion In this study, most of the students indicated surgery and internal medicine as their first specialty choices. Only 5% of the students chose pathology as their first choice. Two-thirds of medical students perceived pathologists do not interact with patients. A significant association was found between younger age groups, enrolling for a pathology course, and having an interest in pathology.

Translation and cross-cultural validation of the non-invasive prenatal testing questionnaire in Arabic.

OBJECTIVES: To translate and cross-culturally adapt a Swedish questionnaire to Arabic to assess the awareness of pregnant women in Saudi Arabia regarding the availability of an accurate and safe prenatal screening procedure. METHODS: The study was conducted at the Obstetrics and Gynecology Clinic, King Abdulaziz Medical City, Riyadh, Saudi Arabia between December 2018 to April 2019. The non-invasive prenatal testing (NIPT) questionnaire, translated and validated in Arabic. Cronbach's alpha reliability testing was carried out to validate the Arabic version of the questionnaire. The sample size was 100 pregnant women, at any gestational period, from 20 to 44 years old. This is a prospective cross-sectional. RESULTS: An Arabic translated, and culturally validated questionnaire related to the attitudes, knowledge, and self-perceived probability of delivering a child with chromosomal abnormality.  Conclusion: We translated and validated the NIPT questionnaire to assess the attitude and awareness of pregnant women regarding the availability of the NIPT.
