Background/Aims: This study aimed to evaluate the performance of the Model for End-Stage Liver Disease (MELD) 3.0 for predicting mortality and liver-related complications compared with the Child-Pugh classification, albumin-bilirubin (ALBI) grade, the MELD, and the MELD sodium (MELDNa) score. Methods: We evaluated a multicenter retrospective cohort of incorporated patients with cirrhosis between 2013 and 2019. We conducted comparisons of the area under the receiver operating characteristic curve (AUROC) of the MELD3.0 and other models for predicting 3-month mortality. Additionally, we assessed the risk of cirrhosis-related complications according to the MELD3.0 score. Results: A total of 3,314 patients were included. The mean age was 55.9±11.3 years, and 70.2% of the patients were male. Within the initial 3 months, 220 patients (6.6%) died, and the MELD3.0had the best predictive performance among the tested models, with an AUROC of 0.851, outperforming the Child-Pugh classification, ALBI grade, MELD, and MELDNa. A high MELD3.0score was associated with an increased risk of mortality. Compared with that of the group with a MELD3.0 score <10 points, the adjusted hazard ratio of the group with a score of 10–20 pointswas 2.176, and that for the group with a score of ≥20 points was 4.892. Each 1-point increase inthe MELD3.0 score increased the risk of cirrhosis-related complications by 1.033-fold. The risk of hepatorenal syndrome showed the highest increase, with an adjusted hazard ratio of 1.149, followed by hepatic encephalopathy and ascites. Conclusions The MELD3.0 demonstrated robust prognostic performance in predicting mortality in patients with cirrhosis. Moreover, the MELD3.0 score was linked to cirrhosis-related complications, particularly those involving kidney function, such as hepatorenal syndrome and ascites.

Tattooing is an invasive procedure that involves the introduction of permanent pigments into the dermis, and is categorized as a medical procedure in Korea. Despite the medical, cosmetic, and aesthetic purposes of tattooing, legislative proposals to allow non-medical personnel to perform tattooing have consistently been rejected on public health grounds, prioritizing health and safety considerations. Professional organizations have maintained a consistent position, highlighting the risks of allowing non-medical individuals to perform tattooing. These risks include procedural complications, use of unsafe practices, and inadequate legal frameworks to ensure accountability.Addressing such issues requires careful consideration beyond economic or convenience factors, with an emphasis on public health policies. To address these concerns, the Korean Dermatological Research Foundation convened its 1st Policy Forum on October 6, 2024. The forum discussed the safety aspects, medical complications, and legal implications of tattooing performed by non-medical personnel. These findings highlight the significant risks and regulatory gaps associated with such practices, underscoring the need for a comprehensive review and stringent regulations to protect public health.

Purpose: We aimed to determine whether the clinical outcomes of antegrade and retrograde extra-articular Kirschner wire (K-wire) pinning differed in proximal phalanx base fractures. Methods: This retrospective study investigated 73 patients aged ≥18 years with extra-articular proximal phalanx base fractures that were treated by closed K-wire pinning between January 2014 and June 2023. Patients were analyzed according to whether the K-wire fixation was antegrade or retrograde. We analyzed demographics, injury characteristics, the number of K-wires applied, surgical duration, the interval before implant removal, and when physical therapy was started. Radiological outcomes included the amount of time required for radiographically confirmed bone union. Clinical outcomes consisted of complications, total active motion (TAM), and the Michigan Hand Outcomes Questionnaire (MHQ). Results: We treated 29 and 44 patients using antegrade and retrograde K-wire fixation, respectively. The overall complication rate was higher in the antegrade group than in the retrograde group (13.8% vs. 9.1%), although this difference was not statistically significant. Similarly, no significant between-group differences were detected in the length of time required for bone union and implant removal, TAM, and MHQ scores. Conclusion Proximal phalanx base fractures were equally and effectively treated by antegrade and retrograde K-wire fixation. Therefore, the direction of K-wire fixation can be chosen based on surgeons’ preferences and experience.

Purpose: This retrospective study aimed to identify factors influencing hand flexor tendon rerupture and to develop preventive strategies for patients who have undergone hand flexor tendon repair. Methods: In total, 287 patients who underwent hand flexor tendon repair between January 2011 and June 2022 were included. Patients with thumb injuries, amputations, bone injuries, extensor tendon injuries, and those with less than 3 months of follow-up were excluded. Patients were divided into rerupture and non-rerupture groups. Events leading to ruptures were also investigated. The two groups were compared according to sex, age, occupation, smoking status, history of diabetes mellitus, injury characteristics, core suture method, and timing of the rehabilitation course. Results: Of the 287 patients, 19 experienced rerupture (6.6%). The mean time to rerupture was 25.3 days. Reruptures occurred due to unknown causes in nine cases (47.4%), noncompliance with medical recommendations in seven cases (36.8%), and trauma in three cases (15.8%). Among the investigated factors, little finger injury and concurrent flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) ruptures were significantly associated with rerupture. Little difference was noted in the core suture methods and timing of the rehabilitation course between the two groups. Conclusion To minimize the risk of rerupture, patients should strictly adhere to medical recommendations and avoid any activities that could cause trauma for at least 1 month after surgery, which is the critical period for tendon remodeling. Patients with little finger injuries as well as concurrent FDS and FDP ruptures require special attention and careful monitoring.
