Background/Aims: We previously reported that patients with moderate-to-severe ulcerative colitis (UC) often experience common mental disorders (CMDs) such as anxiety and depression, necessitating immediate psychological interventions within the first 4 weeks of diagnosis. In this 3-year follow-up study of the MOSAIK cohort in Korea, we examined the effects of CMDs at initial diagnosis on clinical outcomes and health-related quality of life (HRQoL). Methods: We examined differences in clinical outcomes (evaluated based on clinical response, relapse, hospitalization, and medication use) and HRQoL (assessed using the Inflammatory Bowel Disease Questionnaire [IBDQ] and Short Form 12 [SF-12]) according to Hospital Anxiety and Depression Scale (HADS) scores at diagnosis. Results: In a study involving 199 UC patients, 47.7% exhibited significant psychological distress (anxiety and/or depression) at diagnosis. Clinical follow-up showed no major differences in outcomes, including remission rates, response rates, or hospitalization rates, between patients with anxiety or depression at diagnosis and patients without anxiety or depression at diagnosis. The HRQoL at the end of follow-up was notably lower in those with baseline CMDs, particularly anxiety, across all domains of the IBDQ and SF-12. Linear mixed-effect models revealed that higher HADS scores, as well as higher Mayo scores, were independently associated with lower IBDQ scores and both summary domains of the SF-12. Additionally, regular attendance at follow-up visits during the study period was also related to improvements in HRQoL (all p<0.05). Conclusions While CMDs present at the time of UC diagnosis did not influence long-term clinical outcomes, they persistently impaired HRQoL. Our findings support the routine incorporation of psychological interventions into the long-term management of moderate-to-severe UC.

Background: Chromosomal alterations serve as diagnostic and prognostic markers in acute leukemia. Given the evolving landscape of chromosomal abnormalities in acute leukemia, we previously studied these over two periods. In this study, we investigated the frequency of these abnormalities and clinical trends in acute leukemia in Korea across three time periods. Methods: We retrospectively analyzed data from 1,787 patients with acute leukemia (319 children and 1,468 adults) diagnosed between 2006 and 2020. Conventional cytogenetics, FISH, and multiplex quantitative PCR were used for analysis. The patient groups were divided according to the following three study periods: 2006–2009 (I), 2010–2015 (II), and 2016–2020 (III). Results: Chromosomal aberrations were detected in 92% of patients. The PML::RARA translocation was the most frequent. Over the 15-yr period, chromosomal aberrations showed minimal changes, with specific fusion transcripts being common among patients.ALL was more prevalent in children than in adults and correlated significantly with the ETV6::RUNX1 and RUNX1::RUNX1T1 aberrations. The incidence of ALL increased during the three periods, with PML::RARA remaining common. Conclusions The frequency of chromosomal abnormalities in acute leukemia has changed subtly over time. Notably, the age of onset of adult AML has continuously increased. Our results may help in establishing diagnoses and clinical treatment strategies and developing various molecular diagnostic platforms.

Background: Deceased donor liver transplantation (DDLT) and living donor liver transplantation (LDLT) are employed to address highly urgent patients, including those with acute liver failure (ALF), acute-on-chronic liver failure (ACLF), or critical cirrhosis. This study compares outcomes between LDLT and DDLT patients with ALF, ACLF, or critical cirrhosis in highly urgent LDLT (HU-LDLT) applications. Methods: This study conducted a retrospective analysis of the Korean Network for Organ Sharing (KONOS) data, which included 391 consecutive HU-LDLT applications from 2017 to 2021. Results: The proportion of DDLT was 15.1% (n=59) within the cohort of HU-LDLT applications. The prevalence of hepatorenal syndrome, duration of pre-transplant intensive care unit (ICU) care, incidence of pre-transplant continuous renal replacement therapy, and median model for end-stage liver disease scores were significantly greater and prolonged in DDLT patients compared to LDLT patients. Statistical analysis revealed no significant differences in postoperative complications or overall survival between the two groups. In the multivariate analysis, only pre-transplant ventilator care emerged as a significant predisposing factor for mortality. Conclusion The present study indicates that LDLT is a viable option, yielding comparable perioperative and long-term outcomes to DDLT for HU patients, which can encourage living liver donation to overcome organ shortages in HU patients.

Background and Objectives: Cognitive behavioral therapy (CBT) is a treatment option for subjective tinnitus. There are many reports on its clinical efficacy, but the protocol has not been well established. The purpose of this study was to set an outpatient-based CBT protocol and evaluate its clinical efficacy for tinnitus.Subjects and Method A total of 85 chronic tinnitus patients was assessed in this prospective study. After evaluating for eligibility, 30 patients completed CBT based on a protocol of 5 weekly sessions in an outpatient setting. Therapeutic efficacy was assessed by Tinnitus Handicap Inventory (THI) questionnaires and visual analogue scale (VAS) for tinnitus. The initial scores were compared with the final scores, which were assessed a month after the fifth CBT session. Results: The results showed that CBT reduced THI and VAS scores significantly (p<0.05). Conclusion The results of the study suggest that an outpatient-based CBT protocol can be clinically beneficial for patients with tinnitus.

Background and Objectives: Surgical decision-making for papillary thyroid cancer (PTC) relies on accurate preoperative staging, where ultrasonography plays a crucial role in predicting outcomes. We aimed to analyze the predictive effects of preoperative sonographic findings on pathological characteristics. Materials and Methods: Retrospective study was performed using ultrasonographic images and clinico-pathologic data of papillary thyroid cancer patients who underwent total thyroidectomy or lobectomy between March 2016 and May 2020. Finally, 152 patients and 169 tumors were analyzed. Results: Mean age of patients was 54.2±14.2 years and the proportion of female was 75.7%. Tumor size was 13.6±10.3 mm and the proportions of extrathyroidal extension (ETE) and lymph node (LN) involvement were 52.2% and 23.0%, respectively. Preoperative sonographic findings, including ETE, tumor margin, echogenicity, and K-TIRDAS, were significantly associated with pathological ETE.Other pathological characteristics, including LN involvement, lymphovascular invasion, and resection margin positivity, were more observed in patients with more aggressive findings on preoperative sonography; however, we could not find statistical significances. Conclusion This study showed that preoperative sonographic characteristics, such as sonographic ETE, tumor margin, echogenicity, and K-TIRADS, can provide valuable insights into predicting pathological ETE in PTC patients.
