Objective: Bipolar disorder (BD) is marked by significant change in mood and energy levels with sleep disturbance a common feature, resulting in diminished quality of life and impaired daily functioning. This study assessed the association between BD-polygenic risk scores (PRS) and hypnotics in bipolar I disorder (BD-I) patients. Methods: Large-sample data were collected from the genome-wide association study of a multicenter Bipolar Genomic Study, and 1,394 BD-I patients with available medication information were divided into two groups depending on whether they used hypnotics or not. The Diagnostic Interview for Genetic Studies (DIGS) score was used to assess the clinical manifestations and function of the participants and the association between the use of hypnotics and genetic risk was analyzed. Results: Of the 1,394 total participants, 556 (40%) patients received hypnotics, mostly benzodiazepines, administered singly or in combination with other sleeping agents such as, Z-drugs, melatonin-related drugs, and trazodone. The DIGS score was significantly higher for negative categories in the group prescribed hypnotics as was the BD-PRS score, according to the four p value thresholds (p = 0.3, 0.2, 0.1, and 0.05). Logistic regression analysis confirmed a statistically significant association between the BD-PRS and hypnotic use. Conclusion Our results suggest an association between hypnotic use and genetic susceptibility to BD. Sleep disturbances in participants were based on the prescription status of hypnotics supporting the hypothesis that sleep disturbances may be associated with genetic aspects of BD-I. Further genetic studies on genetic overlaps between BD and specific phenotypes or medication responses are required.

Purpose: This study aimed to report the results from an early-phase study of rivoceranib, an oral tyrosine kinase inhibitor highly selective for vascular endothelial growth factor receptor 2, in patients with advanced solid tumors. Materials and Methods: In this open-label, single-arm, dose-escalating, multicenter three-part phase 1/2a trial, patients had advanced solid tumors refractory to conventional therapy. Part 1 evaluated the safety and pharmacokinetics of five ascending once-daily doses of rivoceranib from 81 mg to 685 mg. Part 2 evaluated the safety and antitumor activity of once-daily rivoceranib 685 mg. Part 3 was conducted later, due to lack of maximum tolerated dose determination in part 1, to evaluate the safety and preliminary efficacy of once-daily rivoceranib 805 mg in patients with unresectable or advanced gastric cancer. Results: A total of 61 patients were enrolled in parts 1 (n=25), 2 (n=30), and 3 (n=6). In parts 1 and 2, patients were white (45.5%) or Asian (54.5%), and 65.6% were male. The most common grade ≥ 3 adverse events were hypertension (32.7%), hyponatremia (10.9%), and hypophosphatemia (10.9%). The objective response rate (ORR) was 15.2%. In part 3, dose-limiting toxicities occurred in two out of six patients: grade 3 febrile neutropenia decreased appetite, and fatigue. The ORR was 33%. Conclusion The recommended phase 2 dose of rivoceranib was determined to be 685 mg once daily, which showed adequate efficacy with a manageable safety profile (NCT01497704 and NCT02711969).

Background: Concurrently extrahepatic malignancy (EHM) has long been considered a relative contraindication to liver transplantation because of cancer recurrence. However, we were frequently challenged as living donor liver transplantation (LDLT) may be the only life-saving option available in the setting of end-stage liver disease, or hepatocellular carcinoma (HCC) with concurrent EHM. In this study, we aim to analyze the outcome of adult LDLT with concurrent EHM at the time of LDLT. Methods: Of 2,448 adults who underwent LDLT from May 1996 to January 2023 at our institution, we retrospectively analyzed data for 16 patients with an EHM treated within 6 months at the time of LDLT. Results: Among 16 patients, one patient died of postoperative liver failure, and another died 3 months post-surgery due to bowel perforation. The cumulative overall survival rates at 1-year, 3-year, and 5-year were 87.5%, 78.8%, and 68.9%, respectively. Five patients died during follow-up; only one patient died due to a cancer-related cause. None of the eight patients with low-risk EHM showed EHM recurrence after LDLT. EHM recurrence occurred in one patient with intermediate risk, and cancer progression was seen in one patient with high-risk EHM. Concurrent HCC was present in six patients, and HCC recurrence occurred in two (33.33%). There was no statistically significant difference in survival between patients with hematologic (n=5) and non-hematologic (n=11) EHM (p=0.891). Conclusion Our study shows a high survival rate for LDLT in patients with concurrently EHM. Hence, we suggest that concurrent EHM should not be a contraindication to LDLT even when ‘minimum remission times’ have not yet elapsed.

Background: The coronavirus disease 2019 (COVID-19) pandemic has caused significant changes. This study aimed to investigate the impact of COVID-19 on patients with chronic pain. Methods: Patients with chronic pain from 23 university hospitals in South Korea participated in this study. The anonymous survey questionnaire consisted of 25 questions regarding the following: demographic data, diagnosis, hospital visit frequency, exercise duration, time outside, sleep duration, weight change, nervousness and anxiety, depression, interest or pleasure, fatigue, daily life difficulties, and self-harm thoughts. Depression severity was evaluated using the Patient Health Questionnaire-9 (PHQ-9). Logistic regression analysis was used to investigate the relationship between increased pain and patient factors. Results: A total of 914 patients completed the survey, 35.9% of whom had decreased their number of visits to the hospital, mostly due to COVID-19. The pain level of 200 patients has worsened since the COVID-19 outbreak, which was more prominent in complex regional pain syndrome (CRPS). Noticeable post-COVID-19 changes such as exercise duration, time spent outside, sleep patterns, mood, and weight affected patients with chronic pain. Depression severity was more significant in patients with CRPS. The total PHQ-9 average score of patients with CRPS was 15.5, corresponding to major depressive orders. The patients’ decreased exercise duration, decreased sleep duration, and increased depression were significantly associated with increased pain. Conclusions COVID-19 has caused several changes in patients with chronic pain.During the pandemic, decreased exercise and sleep duration and increased depression were associated with patients’ increasing pain.

Esophageal achalasia is a primary motility disorder characterized by insufficient lower esophageal sphincter relaxation and loss of esophageal peristalsis. Achalasia is a chronic disease that causes progressive irreversible loss of esophageal motor function. The recent development of high-resolution manometry has facilitated the diagnosis of achalasia, and determining the achalasia subtypes based on high-resolution manometry can be important when deciding on treatment methods. Peroral endoscopic myotomy is less invasive than surgery with comparable efficacy. The present guidelines (the “2019 Seoul Consensus on Esophageal Achalasia Guidelines”) were developed based on evidence-based medicine; the Asian Neurogastroenterology and Motility Association and Korean Society of Neurogastroenterology and Motility served as the operating and development committees, respectively. The development of the guidelines began in June 2018, and a draft consensus based on the Delphi process was achieved in April 2019. The guidelines consist of 18 recommendations: 2 pertaining to the definition and epidemiology of achalasia, 6 pertaining to diagnoses, and 10 pertaining to treatments. The endoscopic treatment section is based on the latest evidence from meta-analyses. Clinicians (including gastroenterologists, upper gastrointestinal tract surgeons, general physicians, nurses, and other hospital workers) and patients could use these guidelines to make an informed decision on the management of achalasia.

PURPOSE: This study aimed to evaluate the situations and problems of the current health insurance fees for trauma surgeries. METHODS: We reviewed the medical records and billing data from trauma surgeries performed in the hospital from August 2012 to July 2014. The name and number of surgeries were investigated and the code and number of operations prescribed by surgeons were compared with the number of cases actually billed to insurance. In addition, the results returned by the Health Insurance Review & Assessment Services (HIRA) after deduction were investigated and compared to verify the insurance review findings. RESULTS: During the study period, total 1,534 trauma surgical procedures were performed for a total of 253 trauma patients. Based on names, 1,092 procedures were performed; however, 442 cases (28.8%) could not be prescribed because of lack of proper insurance codes for the procedures. A total of 1,046.5 surgical procedures were prescribed by surgeons, adjusted by the insurance team, and finally billed to the HIRA; 162 bills were returned from the HIRA after rate reductions, corresponding to a reduction rate of 15.5%. The major reason for reduction was “fee criteria and limited number”. The compensation rate for billed surgical procedures was 84.5%. CONCLUSION: The high reduction and low compensation rate for trauma surgery under the current Korean National Health Insurance System need to be reviewed and improved. Furthermore, it is necessary to establish new criteria for surgical procedures fees for latest ones such as damage control surgery performed on severe trauma patients.
