Efficacy and safety of time-restricted eating in metabolic dysfunction-associated steatotic liver disease.

Background & Aims: Time-restricted eating (TRE) may improve weight loss, insulin resistance, and body composition, which are key factors in the pathophysiology of metabolic dysfunction-associated steatotic liver disease (MASLD). However, evidence on the efficacy of TRE in patients with MASLD is limited. This study aimed to evaluate the potential benefits of TRE in patients with overweight or obesity and MASLD.

Investigation on the factors associated with maintenance of paliperidone long-acting injection in the real-world treatment of patients with schizophrenia.

Background: Long-acting injectable (LAI) antipsychotics have been shown to improve adherence and clinical outcomes in schizophrenia treatment. However, issues with compliance and early discontinuation of LAIs remain a significant challenge in real-world settings. Understanding the factors influencing successful initiation and maintenance is essential to maximize their clinical benefits.

Aspartate aminotransferase-to-platelet ratio index outperforms Fibrosis-4 in 2843 Korean patients with metabolic dysfunction-associated steatotic liver disease.

Aim: The definition of metabolic dysfunction-associated steatotic liver disease (MASLD) has recently been proposed. We aim to investigate the diagnostic efficacy of noninvasive fibrosis markers in predicting liver fibrosis in patients with nonalcoholic fatty liver disease (NAFLD), metabolic dysfunction-associated fatty liver disease (MAFLD), and MASLD.

Methods: This retrospective study involved 2843 patients diagnosed with steatotic liver disease at six tertiary hospitals in South Korea.

Relationship between continuity of primary care and hospitalisation for patients with COPD: population-based cohort study from South Korea.

Objectives: The existing evidence for the impacts of continuity of care (COC) in patients with chronic obstructive pulmonary disease (COPD) is low to moderate. This study aimed to investigate the associations between relational COC within primary care and COPD-related hospitalisations using a robust methodology.

Design: Population-based cohort study.

Temporal trends and long-term outcomes of radiofrequency ablation for hepatocellular carcinoma within the Milan criteria.

No study has analysed the temporal trends of the long-term results and clinical characteristics of patients with hepatocellular carcinoma (HCC) treated using radiofrequency ablation (RFA). Therefore, we examined temporal trends of characteristics of patients and treatment-naïve HCCs within the Milan criteria treated by RFA over 20 years. We retrospectively analysed 1099 patients with HCC within the Milan criteria treated with percutaneous RFA from January 2000 to December 2019.

Barcode and radio frequency identification utilization varied across Korean hospitals.

Barcodes and radio frequency identification (RFID) are increasingly used in health care to improve patient safety. However, studies on their utilization in clinical settings are limited. This study aimed to comprehensively examine the utilization status of barcodes and RFID in Korean hospitals, recognize the effects and obstacles associated with utilization, and explore the measures to expand the applications of barcodes and RFID.

Diagnostic Performance of the Fibrosis-4 Index and Nonalcoholic Fatty Liver Disease Fibrosis Score in Lean Adults With Nonalcoholic Fatty Liver Disease.

Importance: The diagnostic performance of the fibrosis-4 index (FIB-4) and nonalcoholic fatty liver disease (NAFLD) fibrosis score (NFS) for advanced fibrosis in lean patients with NAFLD is limited.

Objective: To evaluate the diagnostic performance of the FIB-4 and NFS in lean individuals with NAFLD.

Design, Setting, And Participants: This diagnostic study included adults with biopsy-proven NAFLD from 6 referral centers in Asia from 1995 to 2019.

Proposal of a Novel Serological Algorithm Combining FIB-4 and Serum M2BPGi for Advanced Fibrosis in Nonalcoholic Fatty Liver Disease.

Background/aims: Noninvasive methods have become increasingly critical in the diagnosis of fibrosis in chronic liver diseases. Herein, we compared the diagnostic performance of serum Mac2 binding protein glycosylation isomer (M2BPGi) and other serological panels for fibrosis in patients with nonalcoholic fatty liver disease (NAFLD) and proposed an improved two-step diagnostic algorithm for advanced fibrosis.

Methods: We enrolled 231 patients diagnosed with NAFLD who underwent a liver biopsy.

Chronic airway disease as a major risk factor for fractures in osteopenic women: Nationwide cohort study.

Introduction: The study aimed to demonstrate the risk factors for fractures and to develop prediction models for major osteoporotic and hip fractures in osteopenic patients using the nationwide cohort study in South Korea.

Methods: The study was a retrospective nationwide study using the national screening program for transitional ages from the National Health Insurance Services database in Korea from 2008 to 2019. Primary outcomes were incident fracture events of major osteoporotic and hip fractures.

A risk scoring system to predict clinical events in chronic hepatitis B virus infection: A nationwide cohort study.

Many patients with chronic hepatitis B do not receive adequate follow-up. This study aimed to develop a risk score to predict clinical events in patients with chronic hepatitis B virus (HBV) infection at the population level for identifying patients at high risk to warrant regular follow-up. This study analysed population-based data from the nationwide claims database of South Korea obtained between 2005 and 2015.

Association of aspirin and statin use with the risk of liver cancer in chronic hepatitis B: A nationwide population-based study.

Background & Aims: Aspirin and statins have been suggested to prevent hepatocellular carcinoma (HCC). However, the combined effects of aspirin and statins on HCC risk in patients with chronic hepatitis B (CHB) are not clear.

Methods: A nationwide nested case-control study was performed with data from the National Health Insurance Service gathered between 2005 and 2015 in Korea.

Time- and Dose-Dependent Association of Statin Use With Risk of Clinically Relevant New-Onset Diabetes Mellitus in Primary Prevention: A Nationwide Observational Cohort Study.

Background Given that statins are increasingly being used for primary-prevention, the public concerns regarding the risk of new-onset diabetes mellitus associated with statin use may be an issue. Methods and Results Using healthcare data from the national health insurance examinees, our study comprised a cohort of adults aged ≥40 years with hypercholesterolemia who would be eligible for statin therapy for primary prevention from 2005 to 2012. The primary outcome was the occurrence of clinically relevant new-onset diabetes mellitus requiring medical therapy.

Methodology for Developing Evidence-Based Clinical Imaging Guidelines: Joint Recommendations by Korean Society of Radiology and National Evidence-Based Healthcare Collaborating Agency.

This paper is a summary of the methodology including protocol used to develop evidence-based clinical imaging guidelines (CIGs) in Korea, led by the Korean Society of Radiology and the National Evidence-based Healthcare Collaborating Agency. This is the first protocol to reflect the process of developing diagnostic guidelines in Korea. The development protocol is largely divided into the following sections: set-up, process of adaptation, and finalization.

Imaging Guidelines for Enhancing Justifications for Radiologic Studies.

Justification in the field of radiology refers to the appropriate use of radiologic imaging modalities, and may be achieved by establishing clinical imaging guidelines (CIGs). Recently, CIGs have been shown to be useful in selecting the proper medical imaging modality, resulting in the reduction of inappropriate radiologic examinations, thereby enhancing justifications. However, the development of CIGs is both time-consuming and difficult as the methodology of evidence-based medicine should be adhered to.
