Factors potentially influencing academic performance among medical students.

BACKGROUND: Studies are needed to examine predictors of success in medical school. The aim of this work is to explore factors that potentially influence excellence of medical students. METHODS: The study was conducted in the Medical Faculty of King Abdulaziz University during October 2012. A self-administered questionnaire was used. Medical students with a grade point average (GPA) ≥4.5 (out of 5) were included and compared to randomly selected medical students with a GPA <4.5, who were available at the time of the study. RESULTS: A total of 359 undergraduate students participated in the study. 50.4% of the sample was students with a GPA ≥4.5. No statistically significant difference regarding the time spent on outings and social events was found. However, 60.7% of high GPA students spend less than 2 hours on social networking per day as compared to 42.6% of the lower GPA students (P<0.01). In addition, 79% of high GPA students prefer to study alone (P=0.02), 68.0% required silence and no interruptions during studying time (P=0.013), and 47% revise their material at least once before an exam (P=0.02). CONCLUSION: Excellent medical students have many different characteristics. For example, they do not use social networking for prolonged periods of time, and they have strong motivation and study enjoyment. Further studies are needed to examine whether these differences have a real impact on GPA or not.

Chemotherapy-induced febrile neutropenia in patients with breast cancer. A multivariate risk assessment model for first cycle chemotherapy.

OBJECTIVE: To identify factors that increase the risk of developing febrile neutropenia (FN) during the first cycle of chemotherapy in breast cancer patients. METHODS: In this retrospective study, we reviewed the records of 211 patients with confirmed breast cancer treated with chemotherapy at the Princess Norah Oncology Center, King Abdulaziz Medical City, Jeddah, Kingdom of Saudi Arabia between January 2010 and May 2012. Statistical analysis was conducted using descriptive analysis, univariate, and multivariate logistic regressions. A multivariate regression of FN occurrence in the first cycle was developed. RESULTS: The median age of patients was 48 years. Febrile neutropenia was documented in 43 (20.3%) of 211 patients. Twenty-one (49%) of the 43 patients had FN during the first cycle of chemotherapy. A multivariate logistic regression revealed that age (odds ratio [OR] 1.059, 95% confidence interval [CI]: 1.007-1.114), non-anthracycline and/or taxane-based chemotherapy regimens (OR of 39.488; 95% CI: 4.995-312.187), and neo-adjuvant chemotherapy (OR of 8.282; 95% CI: 1.667-41.152) were the most important independent risk factors of FN. CONCLUSION: Identifying risk factors of FN may help to target high-risk patients with granulocyte colony-stimulating factor prophylaxis and reduce FN incidences, with subsequent morbidities and mortalities.
