Purpose: This study aimed to determine whether micro-flow imaging (MFI) offers diagnostic performance comparable to that of contrast-enhanced ultrasonography (CEUS) in detecting segmental congestion among patients undergoing living donor liver transplantation (LDLT). Methods: Data from 63 patients who underwent LDLT between May and December 2022 were retrospectively analyzed. MFI and CEUS data collected on the first postoperative day were quantified. Segmental congestion was assessed based on imaging findings and laboratory data, including liver enzymes and total bilirubin levels. The reference standard was a postoperative contrast-enhanced computed tomography scan performed within 2 weeks of surgery. Additionally, a subgroup analysis examined patients who underwent reconstruction of the middle hepatic vein territory. Results: The sensitivity and specificity of MFI were 73.9% and 67.5%, respectively. In comparison, CEUS demonstrated a sensitivity of 78.3% and a specificity of 75.0%. These findings suggest comparable diagnostic performance, with no significant differences in sensitivity (P=0.655) or specificity (P=0.257) between the two modalities. Additionally, early postoperative laboratory values did not show significant differences between patients with and without congestion. The subgroup analysis also indicated similar diagnostic performance between MFI and CEUS. Conclusion MFI without contrast enhancement yielded results comparable to those of CEUS in detecting segmental congestion after LDLT. Therefore, MFI may be considered a viable alternative to CEUS.

This guideline aims to promote the prudent use of antibacterial agents for managing carbapenem-resistant Enterobacterales (CRE) infections in clinical practice in Korea. The general section encompasses recommendations for the management of common CRE infections and diagnostics, whereas each specific section is structured with key questions that are focused on antibacterial agents and disease-specific approaches. This guideline covers both currently available and upcoming antibacterial agents in Korea.

Objectives: This study aimed to determine the time-series changes in provincial diabetes management indices using by results of the 2008-2022 Korea Community Health Survey. Methods: We collected diabetes diagnosis experience rate, treatment rate for people diagnosed with diabetes, annual screening rate for diabetic eye disease complications, and annual screening rate for diabetic kidney disease complications with age-standardized rates from the Regional Health Statistics. The unit of analysis was the nation and 17 provinces and the time-series trend analysis was performed by joinpoint regression using the Joinpoint Regression Program, and the annual percent change (APC) and average APC (AAPC) were estimated, and statistical significance was tested using 95% confidence interval (CI). Results: From 2008-2022, the national AAPC (95% CI) for diabetes diagnosis experience rate steadily increased to 2.77 (2.25-3.27), increasing in all regions, excluding Sejong. The national AAPC for treatment rate for people diagnosed with diabetes was 0.75 (0.47-1.04), with a slight but steady trend toward improvement, excluding Daejeon, Sejong, and Jeonbuk, which showed significant improvement. The national AAPCs for annual screening rates for diabetic eye disease and kidney disease complications were 1.82 (0.99-2.66) and 1.95 (0.60-3. 41), respectively, and the area with the largest change was Sejong. Conclusions In Korea, the diabetes management indices tended to increase and improve, but the trends among provinces varied. Therefore, efforts are needed to address regional disparities in diabetes management.
