Objectives: This study aimed to identify the factors associated with psychiatric emergency department revisits within three months through OpenAI-based natural language analysis of medical records and develop a predictive model for revisits. Methods: A retrospective chart review was conducted by analyzing medical records of a general hospital over a 5-year period, from March 1, 2020 to March 1, 2025, using a GPT-4o mini API (application programming interface). The main reasons for psychiatric consultation were categorized into the top 10 causes, which included the following: suicidality (ideation or attempt), depressive symptoms, anxiety or panic symptoms, substance or alcohol use problem, cognitive or mental fluctuation, impulsiveness or aggression, sleep disturbance, psychiatric consultation for medical illness, acute psychosis symptoms, other or unspecified. The socioeconomic factor variables included economic difficulties, low educational attainment, family conflict or stress, interpersonal problems (work/ school), sexual assault or abuse, physical illness or chronic pain, and exposure to celebrity suicide. Results: The revisit group had a significantly lower mean age than the control group, and the proportion of female patients was higher among those who revisited (adjusted residual [AR]=-2.00).Higher revisit rates were observed among patients with persistent mood disorder (AR=+11.18), acute stress or adjustment disorder (AR=+2.62), suicidality (AR=+6.94), sexual assault or abuse (AR=+6.80), and interpersonal problems (AR=+4.66). These were also presented as major predictive variables in the Shapley Additive exPlanations analysis. Conclusion The risk of revisits could be predicted using only the information from psychiatric emergency medical records. An automated prediction system based on the narrative data in the electronic medical records could be developed.

Recent clinical outcomes of multi-regimen chemotherapy in patients with cholangiocarcinoma (CCC) have shown benefits in terms of overall survival. However, repeated endoscopic biliary drainage (EBD) and serious adverse events negatively affect prolongation of the survival period.The aim of this study was to investigate the prevalence of massive hemobilia and the outcomes of its management with fully covered self-expandable metal stents (FC-SEMSs) in patients with hilum-involving CCC receiving multi-regimen chemotherapy. The methods and effects of FCSEMS placement were retrospectively investigated following the occurrence of massive hemobilia during EBD. A total of 356 patients with CCC received multi-regimen chemotherapy. Among them, 181 patients had hilar invasion, and seven patients (3.9%) developed massive hemobilia during repeated EBD using removable stents. In all cases, the tumor encased the right hepatic artery. In six patients (85.7%), hemostasis was immediately and completely achieved by inserting one or two FC-SEMSs proximal to the hilar invasion area. Therefore, if the tumor encases the right hepatic artery, massive hemobilia is likely to occur during multi-regimen chemotherapy.Thus, prompt placement of a FC-SEMS would be an effective treatment option for massive hemobilia in patients with hilum-involving CCC.

Background and Objectives: This study aimed to analyze the outcomes of Fontan surgery in the Republic of Korea, as there were only a few studies from Asian countries. Methods: The medical records of 1,732 patients who underwent Fontan surgery in 10 cardiac centers were reviewed. Results: Among them, 1,040 (58.8%) were men. The mean age at Fontan surgery was 4.3±4.2 years, and 395 (22.8%) patients presented with heterotaxy syndrome. According to the types of Fontan surgery, 157 patients underwent atriopulmonary (AP) type; 303, lateral tunnel (LT) type; and 1,266, extracardiac conduit (ECC) type. The overall survival rates were 91.7%, 87.1%, and 74.4% at 10, 20, and 30 years, respectively. The risk factors of early mortality were male, heterotaxy syndrome, AP-type Fontan surgery, high mean pulmonary artery pressure (mPAP) in pre-Fontan cardiac catheterization, and early Fontan surgery year. The risk factors of late mortality were heterotaxy syndrome, genetic disorder, significant atrioventricular valve regurgitation (AVVR) before Fontan surgery, high mPAP in pre-Fontan cardiac catheterization, and no fenestration. Conclusions In Asian population with a high incidence of heterotaxy syndrome, the heterotaxy syndrome was identified as the poor prognostic factors for Fontan surgery. The preoperative low mPAP and less AVVR are associated with better early and long-term outcomes of Fontan surgery.

Background: This study aimed to compare the analgesic effects of programmed intermittent epidural boluses (PIEB) and continuous epidural infusion (CEI) for postoperative analgesia after elective cesarean section (CS). Methods: Seventy-four women who underwent elective CS were randomized to receive either PIEB or CEI. The PIEB group received 4 ml-intermittent boluses of 0.11% ropivacaine every hour at a rate of 120 ml/h. The CEI group received a constant rate of 4 ml/h of 0.11% ropivacaine. The primary outcome was the pain score at rest at 36 h after CS. Secondary outcomes included the pain scores during mobilization, time-weighted pain scores, the incidence of motor blockade, and complications-related epidural analgesia during 36 h after CS. Results: The pain score at rest at 36 h after CS was significantly lower in the PIEB group compared with that in the CEI group (3.0 vs. 0.0; median difference: 2, 95% CI [1, 2], P < 0.001). The mean time-weighted pain scores at rest and during mobilizations were also significantly lower in the PIEB group than in the CEI group (pain at rest; mean difference [MD]: 37.5, 95% CI [24.6, 50.4], P < 0.001/pain during mobilization; MD: 56.6, 95% CI [39.8, 73.5], P < 0.001). The incidence of motor blockade was significantly reduced in the PIEB group compared with that in the CEI group (P < 0.001). Conclusions PIEB provides superior analgesia with less motor blockade than CEI in postpartum women after CS, without any apparent adverse events.
