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. Methods: All procedures were guided by fluoroscopy and transthoracic echocardiography.The maximum device placement time with an inflated balloon was 24 hours. Changes in the amount of TR, right ventricular function, and patient hemodynamics were measured during balloon deployment. Results: A total of 7 patients (median age 74), underwent successful device implantation without procedure-related complications. During balloon inflation (median 25 minutes), there were no symptoms or signs indicative of TR intolerance. TR was reduced by 1 grade or greater in all patients, with 2 patients exhibiting a reduction of 3 grades, from torrential TR to a moderate degree. Mild TR after balloon inflation was achieved in 3 patients with baseline severe TR. The TR reduction observed during initial balloon deployment was sustained during the subsequent balloon maintenance period. Conclusions The Pivot-balloon procedure was safe, technically feasible, and effective in reducing TR in patients with severe TR. No periprocedural complications or adverse cardiovascular events were reported during device placement with TR reduction observed in all patients. However, longer-term follow-up is needed to confirm safety and treatment effect.

This review examines the challenges associated with occupational disease surveillance in Korea, particularly emphasizing the limitations of current data sources such as the Industrial Accident Compensation Insurance (IACI) statistics and special health examinations. The IACI system undercounts cases due to its emphasis on severe diseases and restrictions on approvals. Special health examinations, although they cover a broad workforce, are constrained by their annual scheduling, which leads to missed acute illnesses and subclinical conditions. The paper also explores the history of occupational disease surveillance in Korea, highlighting the fragmented and disease-specific approach of earlier systems. The authors introduce the newly established Korea Occupational Disease Surveillance Center (KODSC), a comprehensive nationwide system designed to gather, analyze, and interpret data on occupational diseases through a network of regional centers. By incorporating hospital-based surveillance and focusing on acute poisonings and other sentinel events, the KODSC aims to overcome the limitations of previous systems and promote collaboration with various agencies. Although it is still in the early stages of implementation, the KODSC demonstrates potential for improving data accuracy and contributing valuable insights for public health policy.

Purpose: Relative energy deficiency in sport (REDs) is a syndrome of physiological and/or psychological functioning experienced by female and male athletes that is caused by exposure to problematic low energy availability. For the prevention and intervention of REDs, awareness of REDs among sports physicians is important, but it is largely unknown. This study aimed to survey the awareness and clinical treatment experience of REDs in sports physicians. Methods: We conducted an online survey to assess awareness of the triad and REDs among sports physicians and members of The Korean Society of Sports Medicine. Results: A total of 69 members (62.2% male, including sports physicians) to this survey. Most participants (84.1%) were aware of the triad compared to fewer with awareness regarding REDs (23.2%). People who knew about the difference between REDs and triad was 33.3%, which was lower than those who did not (66.6%). Only 10.1% of the study subjects had experience treating REDs patients, and the biggest difficulty in treating patients was a lack of information and education (50.7%). It appeared that the most information about REDs was obtained from academic conferences (59.4%). Conclusion This survey found relatively low awareness of REDs among physicians treating athletes and sports professionals. Considering the various negative effects of REDs on athlete health and performance, education and promotion are needed to increase awareness among sports physicians and sports professionals.
