RESUMO
Introduction Medical undergraduates' educational programs and clinical experiences are important factors in determining their preferred future career path. Unfortunately, the cardiac surgery specialty is experiencing a decline in medical graduates due to many influencing factors as a lack of involvement with the cardiac surgery specialty and a lack of training centers. A detailed evaluation of the student's knowledge and perceptions about cardiac surgery is required to assess the career options in a specialty like cardiac surgery. This study aims to evaluate medical students' knowledge and perceptions of the cardiac surgical specialty. Methodology This is a cross-sectional study that was approved by the institutional research board of Umm Al-Qura University. Adapting a previously published questionnaire data to fit our scope and aims. Necessary adjustments were made adhering to the cardiac surgery experts' instructions. Data was collected through an electronic survey by Google Forms and distributed through social media apps. Results A total of 637 students participated in the study. The majority (75.2%) admitted to having little knowledge of the specialty of cardiac surgery, and 62.8% reported no interest in it. In addition, 88.9% had never done a cardiac surgery rotation before. One of the top concerns of becoming a cardiac surgeon (45.2%) was the amount of time spent studying and working. Conclusion The findings of our study highlight the value of using innovative and targeted learning methods for medical students to enhance their knowledge and pique their interest in cardiac surgery since it was evident that there was a misperception regarding the scope of cases dealt with by cardiac surgery as opposed to other surgical subspecialists.
RESUMO
The precise association of serum leptin (Lep) with the body mass index (BMI) and blood pressure (BP) is not well known for understanding their involvement in health and disease. Hence, the present study was conducted to investigate the association of BP, BMI and serum Lep levels in young normal-weight (NW) and overweight (OW) male Saudi students. The NW (n: 198) and OW (n: 192) male subjects in the age range of 18-20 years were consulted. The BP was measured with a mercury sphygmomanometer. Leptin Human ELISA Kits were employed for the determination of the serum Lep levels. The mean ± SD values of BMI (kg/m2), Lep (ng/mL), systolic BP (SBP; mmHg), and diastolic BP (DBP; mmHg) all showed significant differences for young OW vs. NW subjects as: 27.52 ± 1.42 vs. 21.49 ± 2.03; 10.70 ± 4.67 vs. 4.68 ± 1.91; 121.37 ± 2.59 vs. 118.51 ± 1.54 and 81.44 ± 1.97 vs. 78.79 ± 1.44, respectively. All associations (among BMI, Lep, SBP and DBP) showed a positive linear and significant correlation, except the nonsignificant correlation of BMI and SBP for the NW group. Other variables showing significant variation for NW vs. OW subjects were: interleukin-6, high sensitivity C-reactive protein, apelin (APLN) and resistin. Serum APLN correlated significantly with Lep, BMI, SBP and DBP in lower and higher levels of BMI, with considerable progressive patterns in both the NW and OW groups and subgroups. The present study in young Saudi male students presents significant variations for BP and serum leptin levels, and a significant positive linear association among serum leptin, BMI and BP.
