Factors Affecting Turkish Medical Students' Pursuit of a Career in Neurosurgery: A Single Center Survey Study.

BACKGROUND: Statistics show that over the past 2 decades, even in high-income countries, fewer and fewer students have listed neurosurgery as their top career option. Literature on medical students' pursuit of neurosurgical careers in middle- and low-income countries are scarce. The aim of this research, conducted in Turkey with a middle-income economy, was to contribute insights relevant to medical education and neurosurgery across the world. METHODS: A survey was conducted with a target sample of fourth-year (167 students), fifth-year (169 students), and sixth-year (140 students) medical students (476 in total) from the Medical School at Istanbul Medeniyet University in Turkey. The response rates of the fourth-, fifth-, and sixth-year students were 62% (104/167), 53% (90/169), and 50% (70/140), respectively (in total, 266, including 147 female and 119 male). RESULTS: In terms of the genuine intention, only 2.5% of men and 2.7% of women were committed to specializing in neurosurgery. This study further revealed that possible reasons for these students' low motivation to specialize in neurosurgery were their beliefs that in neurosurgery, the physical and psychological demands were high, and the night shifts were intense, meaning they would not have a social life or spare time for their hobbies; that morbidity/mortality were high; and that financial incentives were insufficient, especially in public institutions. CONCLUSION: Turkish medical students did not rank neurosurgery at the top of their career choices. Possible reasons for this are socioeconomic factors and the inadequate introduction of neurosurgery to medical students.

Clinicopathologic features and prognostic significance of mixed (Low and high-grade) papillary urothelial carcinoma comparison with low and high-grade papillary urothelial carcinoma.

The World Health Organization/International Society of Urological Pathology (2022 WHO/ISUP) classification categorizes noninvasive carcinomas based on the highest grade observed in a pathology sample. According to this classification, a lesion is classified as mixed-grade (MG) if the highest-grade component comprises less than 5% high-grade (HG) carcinoma [14]. This study included 160 cases of low-grade papillary urothelial carcinoma (LGUC) and 160 cases of HG papillary urothelial carcinoma (HGUC), selected randomly. In addition, 160 consecutive and unselected cases of MG papillary urothelial carcinoma (MGUC) were obtained from all bladder transurethral resection specimens diagnosed with papillary urothelial carcinoma between January 2007 and January 2021. The results of the multivariate analysis showed that histologic grade, invasion of the lamina propria, and the presence of carcinoma in situ at presentation were independent prognostic parameters regarding recurrence-free survival (p = 0.002; hazard ratio (HR) = 1.44, 95% confidence interval (CI) = 1.059-1.956, p = 0.02; and HR = 1.76, 95% CI = 1.159-2.684, p = 0.008, respectively). Histologic grade was the only independent prognostic parameter of disease-specific survival (DSS) (p < 0.001). Comparisons between non-muscle invasive (NMI) MGUC and NMI LGUC, as well as between NMI MGUC and NMI HGUC, revealed statistically significant differences in terms of DSS (HR = 0.07, 95% CI = 0.024-0.252, p < 0.001 and HR = 1.59, 95% CI = 1.023-2.460, p = 0.039, respectively). Our study findings demonstrate statistically significant differences regarding DSS between NMI MGUC and NMI HGUC, as well as between NMI MGUC and NMI LGUC. Therefore, we suggested that considering the presence of less than 5% MGUC as a separate category may be appropriate. However, it is important to validate our results in larger cohorts with longer follow-up periods to establish the clinical significance of MGUC and provide guidance for patient management.
