Purpose: This study analyzed the career paths of medical school graduates in the Daejeon, Sejong, and Chungcheongnam-do (DSC) region of South Korea, focusing on career choice factors at each career path. The ultimate goal was to derive practical insights to improve career guidance in the medical field and enhance professionalism. Methods: Data were collected through in-depth interviews with 10 medical school graduates working in the DSC region. A semi-structured questionnaire was used to explore their career paths, and factors influencing their career decisions. The collected qualitative data were analyzed using the constant comparative method to identify themes and categories. Results: The study results categorized career stages into three phases: “entering medical school,” “choosing a specialty after graduation,” and “choosing a workplace after training.” Career choice factors were classified into “personal factors,” “social factors,” and “job and work environment factors.” The factors influencing career choices differed across each career path. Conclusion This study holds significance in its in-depth analysis of career choice factors across different career paths from a long-term perspective. The findings suggest that effective support for career decision-making in the medical field requires a tailored approach that considers the distinct needs and influencing factors at each career path.

Background: Ischemia-reperfusion (I/R) injury is inevitable during the perioperative period. The pancreas is susceptible to I/R injury. Autophagy, a self-digestion process, is upregulated during I/R injury and strongly induced by hypoxia. This study aims to determine whether dexmedetomidine can decrease pancreatic β-cell damage by regulating autophagy under hypoxia. Methods: INS-1 rat insulinoma cells were cultured in dexmedetomidine before being exposed to cobalt chloride (CoCl2)-induced hypoxia. Cell viability and the expression of autophagy-related proteins (light chain 3B [LC3B]-II, p62, and ATGs) were assessed. The expression of apoptosis-related proteins (BCL-2 and P-BAD) were also evaluated. CoCl2-treated INS-1 cells were pretreated with the autophagosome formation inhibitor, 3-methyladenine (3-MA), to compare its effects with those of dexmedetomidine. Bafilomycin-A1 (Baf-A1) that inhibits autophagosome degradation was used to confirm the changes in autophagosome formation induced by dexmedetomidine. Results: Dexmedetomidine attenuated the increased expression of autophagic proteins (LC3B-II, p62, and ATGs) and reversed the CoCl2-induced reduction in the proliferation of INS-1 cells after hypoxia. Dexmedetomidine also alleviated the decreased expression of the anti-apoptotic protein (BCL-2) and the increased expression of apoptotic protein (BAX). Dexmedetomidine reduces the activation of autophagy through inhibiting autophagosome formation, as confirmed by a decrease in LC3B-II/I ratio, a marker of autophagosome formation, in LC3B turnover assay combined with Baf-A1. Conclusions Dexmedetomidine alleviates the degree of cellular damage in INS-1 cells against CoCl2-induced hypoxia by regulating autophagosome formation. These results provide a basis for further studies to confirm these effects in clinical practice.

Platelet-rich plasma (PRP) is a promising biomaterial rich in bioactive growth factors, offering potential as a therapeutic agent for various diseases. However, its effectiveness in central nervous system disorders like vascular dementia (VaD) remains underexplored. This study investigated the potential of PRP to mitigate VaD progression in vivo. A rat model of VaD was established via bilateral common carotid artery occlusion and hypovolemia operation. Rats were randomly assigned to receive either PRP or platelet-poor plasma (PPP)—the latter being a byproduct of PRP preparation and used as a reference standard—resulting in the groups designated as ‘operated group (OP)+PRP’ and ‘OP+PPP’, respectively. PRP or PPP (500 μl) was administered intraperitoneally on the day of the operation and postoperative days 2, 4, 6, and 8. Cognitive function was assessed using the Y-maze, Barnes maze, and passive avoidance tests. On postoperative day 8, hippocampal samples were subjected to histological and semi-quantitative analyses. OP exhibited significant memory decline compared to controls, while the ‘OP+PRP’ group showed notable improvement. Histological analysis revealed increased neuronal loss and neuroinflammation in OP hippocampi, mitigated in ‘OP+PRP’. Semi-quantitative analysis showed decreased expression of brain-derived neurotrophic factor (BDNF) and its receptor tropomyosin receptor kinase B (TrkB) in OP, restored in ‘OP+PPP’ and further in ‘OP+PRP’. These results highlight PRP’s protective effects against VaD-induced hippocampal damage and cognitive impairment, partially attributed to BDNF/TrkB pathway upregulation.
