Comparative Efficacy of Extracorporeal Versus Conventional Cardiopulmonary Resuscitation in Adult Refractory Out-of-Hospital Cardiac Arrest: A Retrospective Study at a Single Center.

Extracorporeal cardiopulmonary resuscitation (ECPR) has the potential to improve neurological outcomes in patients with refractory out-of-hospital cardiac arrest (OHCA), offering an alternative to conventional cardiopulmonary resuscitation (CCPR). However, its effectiveness in OHCA remains controversial despite advancements in resuscitation techniques. This retrospective single-center study compared neurological outcomes and 30-day survival between ECPR and CCPR patients from January 2014 to January 2022.

Timing for a surgically safe and oncologically prompt pancreatoduodenectomy after preoperative biliary drainage in patients with bile duct cancer.

Background: Preoperative biliary drainage (PBD) is commonly performed in patients with bile duct cancer (BDC). However, data regarding the timing of pancreatoduodenectomy (PD) after PBD are insufficient. This study aimed to investigate the optimal timing for surgically and oncologically safe PD after PBD.

Relationships between Chronic Cough and Asthma Control and Quality-of-Life in Patients with Severe Asthma: A 6-Month Longitudinal Analysis.

Background: The prevalence and clinical implications of chronic cough (CC) in patients with severe asthma receiving asthma treatment remain relatively unknown.

Objective: This study aimed to evaluate the relationships between CC and asthma control and quality-of-life (QoL) in patients with severe asthma through longitudinal analysis.

Methods: Baseline and 6-month follow-up data from the Korean Severe Asthma Registry were analyzed.

Cross-sectional study of lung cancer patients as a potential high-risk factor for abdominal aortic aneurysm.

Background: Abdominal aortic aneurysm (AAA) is more common in Non-small cell lung cancer (NSCLC) patients. Considering that ruptured AAA is potentially fatal, timely management of AAA would result in long-term survival benefits. We assess the prevalence and characteristics of AAA in resectable NSCLC patients who would benefit from AAA surveillance.

Comparative Analysis of Outcomes and Kyphotic Risk Factors After Cervical Laminoplasty in 2 Different Ossification of the Posterior Longitudinal Ligament Groups and Cervical Spondylotic Myelopathy.

Background And Objectives: Cervical laminoplasty is commonly used to treat cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL). Postoperative kyphotic changes can restrict spinal cord dorsal shift, leading to poor neurological outcomes. This study analyzes risk factors for loss of cervical lordosis (LCL) after laminoplasty in 3 groups: CSM, continuous OPLL, and other OPLL.

The Korean Organ Transplant Registry (KOTRY): Third Official Adult Heart Transplant Report.

Background And Objectives: The Korean Organ Transplant Registry (KOTRY) provided data for this third official report on adult heart transplantation (HT), including information from 709 recipients.

Methods: Data from HTs performed at seven major centers in Korea between March 2014 and December 2020 were analyzed, focusing on immunosuppression, acute rejection, cardiac allograft vasculopathy (CAV), post-transplant survival, and mechanical circulatory support (MCS) usage.

Results: The median ages of the recipients and donors were 56.

Comparison of Chemoembolization Outcomes Using 70-150 µm and 100-300 µm Drug-Eluting Beads in Treating Small Hepatocellular Carcinoma: A Korean Multicenter Study.

Objective: To evaluate the outcomes of drug-eluting bead transarterial chemoembolization (DEB-TACE) according to the size of the beads for the treatment of small hepatocellular carcinoma (HCC).

Materials And Methods: This retrospective study included 212 patients with a single HCC ≤5 cm from five tertiary institutions. One hundred and nine patients were treated with 70-150-µm doxorubicin DEBs (group A), and 103 patients received 100-300-µm doxorubicin DEBs (group B).

Efficacy and safety of zoledronic acid in the treatment of osteoporosis: A meta-analysis of randomized controlled trials.

Purpose: Zoledronic acid can inhibit the activity of osteoclasts, and thus, may slow or inhibit bone loss. The purpose of this study was to systematically evaluate the efficacy and safety of zoledronic acid in the treatment of osteoporosis.

Methods: Four databases, PubMed, Embase, Cochrane Library, and Web of Science, were systematically searched up to December 26, 2022.

The Relationship between Seropositive Rheumatoid Arthritis and Congestive Heart Failure: A Nationwide Longitudinal Cohort Study in Korea.

The aim of this nationwide longitudinal cohort study is to determine the risk of congestive heart failure (CHF) associated with a seropositive rheumatoid arthritis (RA) population in Korea. In this study, National Health Insurance Service-Health Screening Cohort (NHIS-HEALS) data from 2002 to 2003 were used. The cohort was followed up with for 12 years until December of 2015.

Optimal Dose of Edoxaban for Very Elderly Atrial Fibrillation Patients at High Risk of Bleeding: The LEDIOS Registry.

Background And Objectives: Optimal anticoagulation in very elderly patients is challenging due to the high risk of anticoagulant-induced bleeding. The aim of this study was to assess outcomes of on-label reduced-dose edoxaban (30 mg) in very elderly patients who had additional risk factors for bleeding.

Methods: This was a multi-center, prospective, non-interventional observational study to evaluate the efficacy and safety of on-label reduced-dose edoxaban in atrial fibrillation (AF) patients 80 years of age or older and who had more than 1 risk factor for bleeding.

Association of Cough Severity with Asthma Control and Quality of Life in Patients with Severe Asthma.

Purpose: Symptoms are important components in determining asthma control and in the adjustment of treatment levels. However, clinical relevance of cough in severe asthma is not well-understood. This study aimed to evaluate the severity and association of cough with patient-reported outcomes (PROs) in patients with severe asthma.

Waking qEEG in older adults with insomnia and its associations with sleep reactivity and dysfunctional beliefs about sleep.

Sleep quality often deteriorates with age, and insomnia among the elderly increases the risks of both physical and psychiatric disorders. To elucidate the mechanisms and identify useful diagnostic biomarkers for insomnia in the elderly, the current study investigated the associations of waking brain activity patterns with susceptibility to stress-induced insomnia (sleep reactivity) and dysfunctional beliefs about sleep, major factors precipitating and maintaining insomnia, respectively. Forty-five participants aged 60 years or older with insomnia completed self-reported measures assessing depression, anxiety, sleep quality, dysfunctional beliefs about sleep, and sleep reactivity.

Shift schedules and circadian preferences: the association with sleep and mood.

Object: We explored the circadian preferences of non-shift workers (non-SWs) and various types of shift workers (SWs), and the associations of these preferences with sleep and mood.

Methods: In total, 4,561 SWs (2,419 women and 2,142 men aged 37.00 ± 9.
