Effect of biologic therapies on quality of life in severe asthma: Findings from the PRISM study.

Background: Anti-type 2 (T2) biologic therapies (biologics) improve exacerbation rates, lung function, and asthma-related quality of life (QoL) in patients with severe T2 asthma. However, studies comparing different biologics are lacking. We evaluated the QoL in patients with severe asthma comprehensively and compare the efficacy of different T2-directed biologics using QoL questionnaires.

Exploring novel MYH7 gene variants using in silico analyses in Korean patients with cardiomyopathy.

Background: Pathogenic variants of MYH7, which encodes the beta-myosin heavy chain protein, are major causes of dilated and hypertrophic cardiomyopathy.

Methods: In this study, we used whole-genome sequencing data to identify MYH7 variants in 397 patients with various cardiomyopathy subtypes who were participating in the National Project of Bio Big Data pilot study in Korea. We also performed in silico analyses to predict the pathogenicity of the novel variants, comparing them to known pathogenic missense variants.

Distorted time perception in patients with neurocognitive impairment.

Background: Time perception is known to be distorted in patients with neuropsychiatric disorders. Therefore, this study aims to investigate the correlation between cognitive decline and time distortion by examining time perception in participants with neurocognitive impairment (Alzheimer's disease [AD], vascular dementia [VD], and Parkinson's disease dementia [PDD]) compared to those with subjective cognitive impairment (SCI).

Methods: Overall, 569 participants with cognitive decline complaints between 2013 and 2022 were investigated.

Local Ablation for Hepatocellular Carcinoma: 2024 Expert Consensus-Based Practical Recommendations of the Korean Liver Cancer Association.

Local ablation for hepatocellular carcinoma, a non-surgical option that directly targets and destroys tumor cells, has advanced significantly since the 1990s. Therapies with different energy sources, such as radiofrequency ablation, microwave ablation, and cryoablation, employ different mechanisms to induce tumor necrosis. The precision, safety, and effectiveness of these therapies have increased with advances in guiding technologies and device improvements.

Safety and efficacy of autologous blood tattooing for preoperative colonic localization: a comparative study with conventional India ink tattooing.

Background: India ink has been a popular choice for a tattooing agent in preoperative endoscopic localization but often results in unfavorable effects. Subsequently, autologous blood tattooing has arisen as an alternative option. Due to the limited availability of comparative studies on the matter, we conducted a study to compare the perioperative outcomes associated with India ink tattooing versus autologous blood tattooing.

Aspirin Monotherapy vs No Antiplatelet Therapy in Stable Patients With Coronary Stents Undergoing Low-to-Intermediate Risk Noncardiac Surgery.

Background: Current guidelines recommend the perioperative continuation of aspirin in patients with coronary drug-eluting stents (DES) undergoing noncardiac surgery. However, supporting evidence is limited.

Objectives: This study aimed to compare continuing aspirin monotherapy vs temporarily holding all antiplatelet therapy before noncardiac surgery in patients with previous DES implantation.

The role of FEV/FVC in the prediction of acute exacerbation of COPD.

Background: Whether the ratio of forced expiratory volume in 1 s to forced vital capacity (FEV/FVC) can be used as a biomarker to predict the risk of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) is unclear.

Methods: To investigate the predictive role of FEV/FVC for AECOPD, we analyzed data from an observational and multicenter cohort study of 2043 patients with COPD in KOREA. Exposures were post-bronchodilator FEV/FVC and/or percentage predicted FEV (FEV%pred).

Local ablation for hepatocellular carcinoma: 2024 expert consensus-based practical recommendation of the Korean Liver Cancer Association.

Local ablation for hepatocellular carcinoma (HCC), a non-surgical option that directly targets and destroys tumor cells, has advanced significantly since the 1990s. Therapies with different energy sources, such as radiofrequency ablation, microwave ablation, and cryoablation, employ different mechanisms to induce tumor necrosis. The precision, safety, and effectiveness of these therapies have increased with advances in guiding technologies and device improvements.

Lifestyle risk behavior and atherosclerotic cardiovascular risk: An analysis using the Korea National Health and Nutrition Examination Survey.

Background: Clustering lifestyle risk behaviors is important for predicting cardiovascular disease risk. However, it is unclear which behavior mediates other ones to influence cardiovascular disease risk. We aimed to assess the causal inference of each lifestyle risk behavior for the atherosclerotic cardiovascular disease (ASCVD) risk of the general population.

Efficacy and Safety of Urethral Catheter with Continuous Infusion of Ropivacaine after Urologic Surgery: A Pilot Prospective Randomized Controlled Trial.

Background: Catheter-related bladder discomfort (CRBD) has been found in many patients with urologic surgery. The authors investigated the effect of analgesic-eluting urethral catheters on postoperative CRBD.

Methods: 60 subjects scheduled for urologic surgery requiring urethral catheterization were randomized prospectively to one of three groups (control arm, 0.

Opicapone for the treatment of early wearing-off in levodopa-treated Parkinson's disease: pooled analysis of patient level data from two randomized open-label studies.

Background: The wearing-off phenomenon is a key driver of medication change for patients with Parkinson's disease (PD) treated with levodopa. Common first-line options include increasing the levodopa dose or adding a catechol-O-methyltransferase (COMT) inhibitor, but there are no trials comparing the efficacy of these approaches. We evaluated the effectiveness of adjunct opicapone versus an additional 100 mg levodopa dose in PD patients with early wearing-off using pooled data from 2 randomized studies.

Impact of Fat Mass on Osteoporosis, Sarcopenia, and Osteosarcopenia in Peritoneal Dialysis Patients.

Introduction: The relationship between fat mass and osteoporosis, sarcopenia, and osteosarcopenia is complex. While higher fat mass generally has a negative impact on bone and muscle health in the general population, the impact in peritoneal dialysis (PD) patients is less well understood.

Methods: In this study of 359 PD patients, sarcopenia was identified using appendicular skeletal muscle per square meter (ASM/m2), with cut-off values of <7.

Impact of COVID-19 on brain connectivity and rehabilitation outcome after stroke.

Background: Coronavirus disease (COVID-19) may induce neurological issues, impacting brain structure and stroke recovery. Limited studies have explored its effects on post-stroke rehabilitation. Our study compares brain structure and connectivity, assessing rehabilitation outcomes based on pre-stroke COVID-19 infection.

Doctor shopping trend of patients before undergoing rotator cuff repair in Korea: a multicenter study.

Background: This study aims to investigate the trend of doctor shopping among patients with rotator cuff tear (RCT) before undergoing surgery and to examine the relevance of these findings to the public.

Methods: A survey was conducted of 326 patients from 10 hospitals (male, 176; female, 150) who underwent arthroscopic rotator cuff repair (ARCR) for symptomatic RCT between September 2019 and February 2020. A questionnaire was used to obtain data regarding the type of medical care service, medical institutions visited before surgery, number of treatments received, and cost of treatment.
