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.

Background: Alcoholic liver disease (ALD) includes a wide clinical spectrum from acute alcoholic hepatitis to severe cirrhosis and/or hepatocellular carcinoma. Until now, there has been no report revealing the bleeding tendency of ALD compared to other diseases in liver transplantation (LT). Thus, we analyzed blood loss and transfusion amounts during operation according to the etiologies of liver disease and model for end-stage liver disease (MELD) score. Methods: Out of 874 recipients who underwent LT, a total of 146 patients were excluded by our exclusion criteria. We compared 728 recipients’ baseline characteristics, operation time, blood loss, and transfusion amounts between ALD and nonALD according to MELD score. Results: The number of patients in the ALD group was 130 (17.9%), and 598 (82.1%) in the non-ALD group. The ALD group showed younger age, higher MELD score, and a higher proportion of deceased donor LT than the non-ALD group. Intraoperative blood loss and transfusions of red blood cells (RBCs), fresh frozen plasma, and platelets were significantly higher in the ALD group. When stratified by MELD score (cut-off: 20), ALD patients in both high and low MELD subgroups demonstrated greater blood loss and RBC transfusion requirements, even when international normalized ratio and platelet counts were similar. In multivariate logistic regression analysis, ALD was a significant risk factor for massive transfusion (odds ratio 1.813, 95% confidence interval 1.158–2.840, p=0.009). Conclusion The ALD group showed increased bleeding tendency than the non-ALD group during LT, irrespective of MELD score. This suggests that transplant surgeons should anticipate greater blood loss and ensure adequate transfusion resources during LT for ALD patients.

Purpose: The purpose of this study was to determine the effects of ankle dorsiflexion, neutral, and plantarflexion on lower extremity muscle activity and break point angle (BPA) during Nordic hamstring exercises. Methods: Twenty-four members of a college soccer club (age, 21.68±2.39 years; height, 175.63±4.76 cm; weight, 71.88±6.29 kg) were recruited to participate in the experiment, and all subjects were measured three times in triplicate for Nordic hamstrings at three different ankle angles with all subjects in one group. Surface electromyography equipment (miniDTS, Noraxon Inc.) was used to acquire 3 seconds of muscle activity data at the starting point (90°) during exercise, and motion analysis software (Kinovea version 0.9.5, Kinovea) was used to collect kinematic data at the point where knee strike angular velocity exceeded 30°/sec for BPA data acquisition. Results: The results of this study, lower extremity muscle activity was not significantly different in the three variants of Nordic hamstring exercises, but BPA was significantly lower in the dorsiflexion position (60.28°±6.35°) compared to the neutral position (65.32°±6.35°) and plantarflexion position (63.82°±7.01°) (p＜ 0.001). Conclusion These results suggest that the dorsi flexion position of the ankle during Nordic hamstring exercises allows the body to maintain the position for a longer period of time against eccentric forces in situations where the body is moving forward. This suggests that the ankle dorsi flexion position can be used as a position for effective Nordic hamstring exercises in amateur soccer players.

Colorectal cancer is the third most common cancer in Korea and the third leading cause of death from cancer. Treatment outcomes for colon cancer are steadily improving due to national health screening programs with advances in diagnostic methods, surgical techniques, and therapeutic agents.. The Korea Colon Cancer Multidisciplinary (KCCM) Committee intends to provide professionals who treat colon cancer with the most up-to-date, evidence-based practice guidelines to improve outcomes and help them make decisions that reflect their patients’ values and preferences. These guidelines have been established by consensus reached by the KCCM Guideline Committee based on a systematic literature review and evidence synthesis and by considering the national health insurance system in real clinical practice settings. Each recommendation is presented with a recommendation strength and level of evidence based on the consensus of the committee.

Background: We aimed to evaluate whether composite blood biomarkers including aldo-keto reductase family 1 member B10 (AKR1B10) and cytokeratin 18 (CK-18; a nonalcoholic steatohepatitis [NASH] marker) have clinically applicable performance for the diagnosis of NASH, advanced liver fibrosis, and high-risk NASH (NASH+significant fibrosis). Methods: A total of 116 subjects including healthy control subjects and patients with biopsy-proven nonalcoholic fatty liver disease (NAFLD) were analyzed to assess composite blood-based and imaging-based biomarkers either singly or in combination. Results: A composite blood biomarker comprised of AKR1B10, CK-18, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) showed excellent performance for the diagnosis of, NASH, advanced fibrosis, and high-risk NASH, with area under the receiver operating characteristic curve values of 0.934 (95% confidence interval [CI], 0.888 to 0.981), 0.902 (95% CI, 0.832 to 0.971), and 0.918 (95% CI, 0.862 to 0.974), respectively. However, the performance of this blood composite biomarker was inferior to that various magnetic resonance (MR)-based composite biomarkers, such as proton density fat fraction/MR elastography- liver stiffness measurement (MRE-LSM)/ALT/AST for NASH, MRE-LSM+fibrosis-4 index for advanced fibrosis, and the known MR imaging-AST (MAST) score for high-risk NASH. Conclusion Our blood composite biomarker can be useful to distinguish progressive forms of NAFLD as an initial noninvasive test when MR-based tools are not available.

Purpose: We used arterial spin labeling (ASL) perfusion magnetic resonance (MR) imaging to evaluate cerebral perfusion abnormalities in patients with seizures within 24 hours of symptom onset. Materials and Methods: A retrospective search of our institutional database identified 27 patients who had undergone ASL perfusion studies for seizures or seizure-like symptoms.The inclusion criteria were as follows: 1) history of seizure, 2) MR examination performed within 24 hour of seizure onset, and 3) localized perfusion abnormality on ASL. We evaluated the presence, location, and extent of perfusion abnormalities on ASL and signal abnormalities on fluid-attenuated inversion recovery (FLAIR), diffusion-weighted image (DWI), and susceptibility-weighted image (SWI), respectively. All pathological MR findings, accompanying focal neurological symptoms, and electroencephalogram (EEG) findings were compared. Results: The mean time from symptom onset to MR examination was 5 h 54 min. All patients (n = 27) showed localized increased perfusion on ASL perfusion imaging. On FLAIR imaging, 20 patients (74.1%) showed hyperintensity in the area of perfusion abnormality.In 19 patients (70.4%), DWI showed hyperintensity of the lesion with decreased apparent diffusion coefficient value (ADC). Seven patients (25.9%) showed a focal parenchymal area of pseudo-narrowed cortical veins on SWI, associated with focal hyperperfusion. In 20 patients (74.1%), the extent of perfusion abnormalities on ASL was greater than that of signal abnormalities on FLAIR or DWI. In 14/16 patients (87.5%) with abnormal EEG findings, the area with EEG findings and the location of the hyperperfusion abnormality on ASL corresponded. Conclusion In patients with seizures within 24 hours of symptom onset, ASL perfusion imaging revealed localized hyperperfusion, which was more frequent than signal intensity abnormalities on FLAIR or DWI. The locations of hyperperfusion areas correlated with EEG abnormalities. Thus, the ASL sequence may be a useful clinical assessment protocol for evaluating patients with seizures.
