Heart failure (HF) is a major cause of mortality and morbidity in South Korea, imposing substantial physical, emotional, and financial burdens on patients and society. Despite the high burden of symptom and complex care needs of HF patients, palliative care and hospice services remain underutilized in South Korea due to cultural, institutional, and knowledge-related barriers. This position statement from the Korean Society of Heart Failure emphasizes the need for integrating palliative and hospice care into HF management to improve quality of life and support holistic care for patients and their families. By clarifying the role of palliative care in HF and proposing practical referral criteria, this position statement aims to bridge the gap between HF and palliative care services in South Korea, ultimately improving patient-centered outcomes and aligning treatment with the goals and values of HF patients.

Vertical positioning of dental implants relative to the cementoenamel junction (CEJ) of the adjacent teeth is essential for maintaining peri-implant bone stability and long-term success. This retrospective study evaluated how the vertical distance from the CEJ affects peri-implant bone loss in patients who had implants positioned at various distances from the CEJ. Bone loss was evaluated using panoramic radiographs over a 2-year follow-up period, with additional consideration of factors such as smoking and diabetes. Implants positioned >4 mm away from the CEJ exhibited a higher mean bone loss; however, this difference was not significant. Smoking significantly influenced bone loss, whereas diabetes and jaw location had no significant effect. These results highlight the potential influence of vertical implant positioning on peri-implant bone health and highlight the importance of appropriate maintenance care to reduce bone loss and ensure long-term implant survival.

The extremely low frequency-electromagnetic field (ELF-EMF) refers to the frequency range of 0-300 Hz. It has been reported that it causes biological effects on cell survival, growth, and function. Structural changes were observed in the cell membranes of bacteria exposed to a certain intensity of ELF-EMF, indicating that exposure of bacteria to ELF-EMF can directly affect the cell membrane and affect the survival and growth of bacteria. The purpose of this study was to investigate the effect of the application of low frequency square wave positive voltages on Aggregatibactor actinomycetemcomitans (A. actinomycetemcomitans), a putative pathogen of periodontal disease. A square wave positive voltage output of 20 V or less at low frequency (0-300 Hz) was applied to A. actinomycetemcomitans in a range of 60 minutes. Changes in the population of bacteria were observed by absorbance measurement, colony forming unit (CFU/ml) evaluation, and high-resolution field-emission scanning electron microscopy (HR FE-SEM). The results show that the most effective offset and frequency in inhibiting bacterial growth are 0.7V and 7.83 Hz (Schumann resonance). As the applied time increased and the voltage increased, it was effective in inhibiting bacterial growth. These results led to the conclusion that bacterial growth can be inhibited even at low frequencies below 10 Hz, and it was experimentally proven that the frequency, voltage setting, and exposure time of ELF-EMF have a significant effect on reducing the growth of A. actinomycetemcomitans.

Recent technical innovation enables faster and more reliable cardiac magnetic resonance (CMR) imaging than before.Artificial intelligence is used in improving image resolution, fast scanning, and automated analysis of CMR. Fast CMR techniques such as compressed sensing technique enable fast cine, perfusion, and late gadolinium-enhanced imaging and improve patient throughput and widening CMR indications. CMR feature-tracking technique gives insight on diastolic function parameters of ventricles and atria with prognostic implications. Myocardial parametric mapping became to be included in the routine CMR protocol. CMR fingerprinting enables simultaneous quantification of myocardial T1 and T2. These parameters may give information on myocardial alteration in the preclinical stages in various myocardial diseases. Four-dimensional flow imaging shows hemodynamic characteristics in or through the cardiovascular structures visually and gives quantitative values of vortex, kinetic energy, and wall-shear stress. In conclusion, CMR is an essential modality in the diagnosis of various cardiovascular diseases, especially myocardial diseases. Recent progress in CMR techniques promotes more widespread use of CMR in clinical practice. This review summarizes recent updates in CMR technologies and clinical research.

The Asian Society of Cardiovascular Imaging-Practical Tutorial (ASCI-PT) is an instructional initiative of the ASCI School designed to enhance educational standards. In 2021, the ASCI-PT was convened with the goal of formulating a consensus statement on the assessment of coronary stenosis and coronary plaque using coronary CT angiography (CCTA). Nineteen experts from four countries conducted thorough reviews of current guidelines and deliberated on eight key issues to refine the process and improve the clarity of reporting CCTA findings. The experts engaged in both online and on-site sessions to establish a unified agreement. This document presents a summary of the ASCI-PT 2021 deliberations and offers a comprehensive consensus statement on the evaluation of coronary stenosis and coronary plaque in CCTA.

The study was conducted to examine the prevalence and degree of peri-implantitis in implant-supported bridges compared to splinted crowns in 3-unit and 4-unit posterior edentulous areas. A total of 229 implant sites from 79 patients who had received implants at the Kyungpook National University Dental Hospital were evaluated. The observation period ranged from 2 to 12 years. Patient characteristics and implant-related factors were investigated. After surgery and prosthetic treatment, radiographic evaluations were performed. Also, to identify factors that could affect the prognosis of the implants, Fisher’s exact tests and chi-square were used. In addition, the mean distance between crestal bone levels and implant platform was compared between implant-supported bridges and splinted crowns using the Mann-Whitney U test. No statistically significant differences were found in the mean distances between implant platforms and bone levels in either restoration type. The prevalence of peri-implantitis was 15% in splinted crowns and 13% in bridges, with restoration type showing no significant association. However, middle implant showed the highest rate of peri-implantitis compared to other positions. Furthermore, bone augmentation and implant sites (maxilla or mandible) showed significant association with peri-implantitis. In conclusion, restoration type does not influence the prevalence or severity of peri-implantitis, but implant position affect the rate of peri-implantitis. Clinicians should consider bone quality when choosing between implant-supported bridges and splinted crowns.
