		                        			 Purpose:
		                        			Developmentally regulated GTP-binding protein 2 (DRG2) regulates microtubule dynamics and G2/M arrest during docetaxel treatment. Poly ADP-ribose polymerase (PARP) acts as an important repair system for DNA damage caused by docetaxel treatment. This study investigated whether DRG2 expression affects response to PARP inhibitors (olaparib) using prostate cancer cell lines PC3, DU145, LNCaP-FGC, and LNCaP-LN3. 
		                        		
		                        			Materials and Methods:
		                        			The cell viability and DRG2 expression levels were assessed using colorimetric-based cell viability assay and western blot. Cells were transfected with DRG2 siRNA, and pcDNA6/V5-DRG2 was used to overexpress DRG2. Flow cytometry was applied for cell cycle assay and apoptosis analysis using the Annexing V cell death assay. 
		                        		
		                        			Results:
		                        			The expression of DRG2 was highest in LNCaP-LN3 and lowest in DU145 cells. Expressions of p53 in PC3, DU145, and the two LNCaP cell lines were null-type, high-expression, and medium-expression, respectively. In PC3 (DRG2 high, p53 null) cells, docetaxel increased G2/M arrest without apoptosis; however, subsequent treatment with olaparib promoted apoptosis. In DU145 and LNCaP-FGC (DRG2 low), docetaxel increased sub-G1 but not G2/M arrest and induced apoptosis, whereas olaparib had no additional effect. In LNCaP-LN3 (DRG2 high, p53 wild-type), docetaxel increased sub-G1 and G2/M arrest, furthermore olaparib enhanced cell death. Docetaxel and olaparib combination treatment had a slight effect on DRG2 knockdown PC3, but increased apoptosis in DRG2-overexpressed DU145 cells. 
		                        		
		                        			Conclusions
		                        			DRG2 and p53 expressions play an important role in prostate cancer cell lines treated with docetaxel, and DRG2 levels can predict the response to PARP inhibitors.

		                        			 Purpose:
		                        			The purpose of this study was to examine the acceptability, availability and sustainability of a pilot prenatal program developed by an interdisciplinary team.  
		                        		
		                        			Methods:
		                        			Out of 19 multicultural women participated in the 6-session prenatal program, 6 women took part in an exit- focus group interview as a part of formative evaluation. The verbatim transcriptions of semi-structured interview data were analyzed using conventional content analysis.  
		                        		
		                        			Results:
		                        			In general, the participants expressed high satisfaction with program content, educators and education methods. A hybrid model including health professionals and community health workers and using online and offline education modes was suggested as a way to disseminate the program at a national level. Interventions using aesthetic approaches such as music and an integrated method such as the introduction of available social services in pregnancy and during the postpartum period may play a role as the facilitator of the program participation of multicultural women. These approaches may also help them develop healthy coping skills, problem solving skills and empowerment in multicultural childbearing women who need to adjust to life in a new country simultaneously taking a new role as a mother.  
		                        		
		                        			Conclusion
		                        			An interdisciplinary prenatal program using a holistic approach contributes to enhancing multicultural women’s empowerment to become a mother in a new country.

		                        			 Many countries have published clinical practice guidelines for appropriate clinical decisions, optimal treatment, and improved clinical outcomes in patients with acute coronary syndrome. Developing guidelines that are specifically tailored to the Korean environment is crucial, considering the treatment system, available medications and medical devices, racial differences, and level of language communication. In 2017, the Korean Society of Myocardial Infarction established a guideline development committee. However, at that time, it was not feasible to develop guidelines, owing to the lack of knowledge and experience in guideline development and the absence of methodology experts. In 2022, the National EvidenceBased Healthcare Collaborating Agency collaborated with a relevant academic association to develop internationally reliable guidelines, with strict adherence to the methodology for evidence-based guideline development. The first Korean acute coronary syndrome guideline starts from the 9 key questions for pharmacotherapy.

		                        			 Background:
		                        			s/Aims: The recent increase in medical school admissions has potentially altered the working conditions of hospitalists in South Korea. This study investigated how these changes have affected the work patterns and responsibilities of hospitalists, particularly in light of the ongoing exodus of medical trainees that began on February 22, 2024. 
		                        		
		                        			Methods:
		                        			We surveyed members of the Korean Society of Hospital Medicine and the Korean Society of Surgery Hospital Medicine Study Group working as hospitalists from April 2 to 30, 2024. The survey was conducted via email and excluded personally identifiable information. Respondents’ characteristics, work types, hours, patient loads, support staff availability, and changes in job scope post-policy were analyzed. 
		                        		
		                        			Results:
		                        			Sixty-three hospitalists responded, with an equitable gender distribution and a median age of 39 years. A significant shift in work patterns was noted, with full-day shifts increasing from 22.2% to 39.7%, and a corresponding decrease in weekday daytime shifts. Work hours also significantly increased from a median of 40 to 45 hours per week. Changes in patient distribution were observed, with fewer hospitalists managing mid-range patient numbers and more handling smaller or larger loads. Despite the increased demands in the latter case, more than 50% of hospitalists reported a lack of support staff and a significant portion did not receive overtime compensation. 
		                        		
		                        			Conclusions
		                        			The increase in medical school admissions and subsequent shifts in hospitalist workloads and hours indicate a strained healthcare system. Hospitalists are taking on more intensive and extended roles. The absence of adequate support staff and adjustments in compensation suggest that further systemic changes are necessary to sustain the efforts of hospitalists, thereby ensuring patient safety and care quality.
