Background: Frailty is prevalent in older adults and represents a dynamic condition that can improve with early detection and interventions focused on influencing factors. Older immigrant populations, marked by diverse cultural backgrounds, distinct health beliefs and behaviors, language barriers, and low health literacy, require a focused exploration of factors influencing frailty. This study examines the perceived factors affecting frailty among older Korean American immigrants (OKAIs).

Article Synopsis
  • The study investigates how certain psychological factors influence posttraumatic growth (PTG) in students who survived the Sewol ferry disaster, indicating that adversity can sometimes lead to positive outcomes in mental health.
  • Data were collected longitudinally from 48 adolescents over six years, assessing various measures such as rumination, meaning in life, and coping strategies.
  • Results showed that both types of rumination, a sense of meaning in life, and adaptive coping methods were all strongly linked to increases in PTG, suggesting these factors can help mitigate negative mental health impacts.

Background And Objectives: Among various emerging catheter-based treatments for severe tricuspid regurgitation (TR), the spacer device can reduce the regurgitation orifice without manipulating the valve leaflet. However, its clinical application has been hampered by traumatic anchoring to the myocardium and the coaxial alignment of the balloon resulting in insufficient TR reduction. This study aimed to evaluate the early-stage safety, technical feasibility, and preliminary efficacy of the novel atraumatic vertical spacer in patients with isolated severe TR.

Background: The advancement of medical interventions towards minimally invasive procedures highlights the crucial role of precise pre-procedural evaluation, particularly in catheter-based treatments for heart and cardiovascular conditions. This study investigates innovative techniques such as mitral loop cerclage (MLC) and transcatheter intramyocardial radiofrequency ablation (TIRA), emphasizing the importance of preprocedural cardiac CT scans for accurate anatomical guidance in these emerging therapies.

Purpose: The objective of this study was to assess the cardiac cycle through examination of the proximal septal vein (ps) for mitral loop cerclage and the distal septal vein (ds) for transcatheter intramyocardial radiofrequency ablation.

Background: Cilostazol has a vasodilatory function that may be beneficial for patients with vasospastic angina (VSA). We conducted a randomized, open-label, controlled trial to compare the efficacy and safety of long-acting cilostazol and isosorbide mononitrate (ISMN) for VSA.

Methods: The study included patients with confirmed VSA between September 2019 and May 2021.
