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: This study focuses on the development of a hydrogel wound patch incorporating natural extracts, designed to function as a sun patch. By maintaining a moist environment and delivering bioactive compounds, the patch promotes wound healing while also providing cooling and ultraviolet (UV) protection. This dual-purpose approach enhances skin recovery and shields damaged areas from external stressors. The study aims to optimize the formulation and evaluate its efficacy for both therapeutic and cosmetic applications. Methods: Hydrogel solutions prepared using acrylamide, glycerol, and carboxymethyl cellulose were enriched with extracts from Saururus chinensis, Styrax japonicus, and Centella asiatica. The enriched solutions were processed into patches and tested for their adhesion, cooling effects, and UV protective abilities. Additionally, the wound healing efficacy was evaluated in a mouse model. Results: The hydrogel patches demonstrated comparable adhesion properties, effective skin cooling, and high UV protection rates similar to those of commercially available products. In the mouse model, the patches significantly improved wound closure and tissue regeneration in the experimental group as compared to the control group. Conclusion The study confirms that hydrogel sun patches enriched with natural extracts have the ability to effectively promote wound healing and offer substantial UV protection and cooling benefits, demonstrating their potential medical and cosmetic applications.

Background: and Purpose: This clinical practice guideline provides evidence-based recommendations for treatment of dementia, focusing on cholinesterase inhibitors and N-methyl-D-aspartate (NMDA) receptor antagonists for Alzheimer’s disease (AD) and other types of dementia. Methods: Using the Population, Intervention, Comparison, Outcomes (PICO) framework, we developed key clinical questions and conducted systematic literature reviews. A multidisciplinary panel of experts, organized by the Korean Dementia Association, evaluated randomized controlled trials and observational studies. Recommendations were graded for evidence quality and strength using Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology. Results: Three main recommendations are presented: (1) For AD, cholinesterase inhibitors (donepezil, rivastigmine, galantamine) are strongly recommended for improving cognition and daily function based on moderate evidence; (2) Cholinesterase inhibitors are conditionally recommended for vascular dementia and Parkinson’s disease dementia, with a strong recommendation for Lewy body dementia; (3) For moderate to severe AD, NMDA receptor antagonist (memantine) is strongly recommended, demonstrating significant cognitive and functional improvements. Both drug classes showed favorable safety profiles with manageable side effects. Conclusions This guideline offers standardized, evidence-based pharmacologic recommendations for dementia management, with specific guidance on cholinesterase inhibitors and NMDA receptor antagonists. It aims to support clinical decision-making and improve patient outcomes in dementia care. Further updates will address emerging treatments, including amyloid-targeting therapies, to reflect advances in dementia management.

Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules, recurrent thyroid cancers (RTCs), and primary thyroid microcarcinomas. The Korean Society of Thyroid Radiology (KSThR) initially developed recommendations for the optimal use of RFA for thyroid tumors in 2009 and revised them in 2012 and 2017. As new meaningful evidence has accumulated since 2017 and in response to a growing global interest in the use of RFA for treating malignant thyroid lesions, the task force committee members of the KSThR decided to update the guidelines on the use of RFA for the management of RTCs based on a comprehensive analysis of current literature and expert consensus.

BACKGROUND/OBJECTIVES: Inflammatory responses are key pathological factors in various canine diseases, making the control of inflammatory responses vital for canine health.This study examined the anti-inflammatory effects of rutin on DH82 cells, a type of canine macrophage, against lipopolysaccharide (LPS)-induced inflammatory responses.MATERIALS/METHODS: The inflammatory in vitro experimental model was established by stimulating canine macrophage DH82 cells with LPS. To evaluate the inflammationpreventative effects of rutin, analyses were conducted using enzyme-linked immunosorbent assay, western blot, and real-time quantitative reverse transcription polymerase chain reaction. RESULTS: Rutin inhibited the LPS-induced increase in the protein and gene levels of proinflammatory cytokines (interleukin [IL]-1β, IL-6, tumor necrosis factor-α), while antiinflammatory cytokines (IL-10, transforming growth factor-β1) levels remained unchanged.Furthermore, rutin suppressed the LPS-induced activation of phosphorylated extracellular signal-regulated kinase, Jun N-terminal kinase, inhibitor of nuclear factor kappa B, and nuclear factor kappa B (NF-κB) in DH82 cells. CONCLUSION Rutin exerts anti-inflammatory effects by inhibiting the mitogen-activated protein kinase-NF-κB signaling pathway and reducing the production of pro-inflammatory cytokines in DH82 cells.

Intraflagellar transport (IFT) particles, a multi-protein apparatus composed of complex A and B, are known to be involved in homeostasis of flagella formation. IFT particles have recently become an interesting topic in Giardia lamblia, which has 4 pairs of flagella. In this experiment, we examined the function of giardial IFT components. When 7 components (IFT121, 140, 20, 46, 52, 81, and 88) of IFT were expressed in Giardia trophozoites as a tagged form with mNeonGreen, all of them were found in both flagella pores and cytoplasmic axonemes. In addition, motor proteins for IFT particles (kinesin-13 and kinesin-2b), were localized to a median body and cytoplasmic flagella, respectively. The CRISPRi-mediated knockdown of IFT88 significantly affected the lengths of all 4 flagella compared to the control cells, Giardia expressing dead Cas9 using control guide RNA. Decreased expression of kinesin-2b also resulted in shortening of flagella, excluding the ventral flagella. Live Giardia cells expressing IFT88-mNeonGreen clearly demonstrated fluorescence in flagella pores and cytoplasmic axonemes. These results on IFT88 and kinesin-2b indicate that IFT complex plays a role in maintenance of G. lamblia flagella.

Objective: Previous studies have reported an association between cancer-related symptoms and perceived social support (PSS). The objective of this study was to analyze whether Chemotherapy-Induced Peripheral Neuropathy (CIPN), a prevalent side effect of chemotherapy, varies according to PSS level using a validated tool for CIPN at prospective follow-up. Methods: A total of 39 breast cancer patients were evaluated for PSS using the Multidimensional Scale of Perceived Social Support (MSPSS) prior to chemotherapy and were subsequently grouped into one of two categories for each subscale: low-to-moderate PSS and high PSS. CIPN was prospectively evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Chemotherapy-Induced Peripheral Neuropathy 20 (CIPN20) at five time points. A linear mixed-effects model with square root transformation was employed to investigate whether the CIPN20 scales varied by PSS level and time point. Results: Statistical analysis of the MSPSS total scale and subscales revealed a significant effect of the friends subscale group and time point on the CIPN20 sensory scale. The sensory scale score of CIPN20 was found to be lower in participants with high PSS from friends in comparison to those with low-to-moderate PSS at 1 month post-chemotherapy (p=0.010). Conclusion This is the first study to prospectively follow the long-term effect of pre-treatment PSS from friends on CIPN. Further studies based on larger samples are required to analyze the effects of PSS on the pathophysiology of CIPN.

The prevalence of postpartum depression (PPD) in Asia is reported to range from 13.53% to 22.31%. However, there remains a gap in the identification of PPD, particularly regarding cultural cutoff points. Therefore, the purpose of this scoping review was to determine the prevalence and associated factors of PPD in Eastern, South-eastern, Western, and Southern Asian countries and analyze the cutoff points of the Edinburgh Postnatal Depression Scale (EPDS) used across these countries. Following Arksey and O'Malley’s five-step scoping review framework, the population was defined as mothers, the concept as the EPDS, and the context as the Asian region. A literature search was conducted using PubMed, Embase, CINAHL, PsycINFO, and Web of Science. The data analysis focused on demographic characteristics, EPDS cutoffs and features, PPD prevalence, and its associated factors. Nineteen studies were selected. Most countries used translated versions of the EPDS with demonstrated reliability and validity. The cutoff scores varied, with most using scores of 10 or higher. The prevalence of PPD ranged from 5.1% to 78.7%. Key associated factors for PPD included cultural factors such as relationships with in-laws and preferences for the newborn’s sex. To improve the accuracy of PPD screening in Asia, the EPDS should be used consistently, and appropriate cutoff criteria must be established. In addition, prevention strategies and programs that reflect the cultural characteristics and social context of Asia need to be developed for the early detection and prevention of PPD.

Helicobacter pylori causes gastric cancer and peptic ulcers, and eradication therapy can reduce the incidence of cancer in high-risk groups. In Korea, discrepancies between the reimbursement criteria and clinical guidelines create clinical challenges. This study investigated the perceptions and practices of experts regarding H. pylori testing during upper gastrointestinal endoscopy and any subsequent eradication therapy. An anonymous 8-question survey was conducted among 51 experts attending the 2024 Korean College of Helicobacter and Upper Gastrointestinal Research Summer Workshop. Only 2% of the experts tested all patients. Testing was performed in 54% of patients with a family history of gastric cancer, 32% of those with atrophic gastritis, 42% of those with dyspeptic symptoms, and 62% of those with iron-deficiency anemia. Among patients with suspected infections (based on endoscopic findings) and eligible for selective reimbursement, 82% underwent H. pylori testing. Age did not influence testing decisions for 60% of the experts, and 57% considered factors other than age when deciding on eradication therapy. The practices of the experts varied depending on the patient’s clinical condition and economic burden. Aligning clinical guidelines with the reimbursement criteria is necessary to reduce confusion and ensure appropriate patient care.

Background/Aims: To determine the effectiveness of tyrosine kinase inhibitor (TKI) plus reduced-intensity therapy in adult patients with newly diagnosed Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph-positive ALL), this retrospective study compared treatment outcomes and induction mortality according to backbone regimen intensity. Methods: The data of 132 patients diagnosed with Ph-positive ALL were retrospectively collected from five centers. Patients received imatinib plus intensive chemotherapy (modified VPD, KALLA1407, or hyper-CVAD) or reduced-intensity chemotherapy (EWALL) for curative purposes. This study analyzed 117 patients, of which 35,22,46, and 14 received modified VPD, KALLA1407, hyper-CVAD, and EWALL, respectively. All patients used imatinib as a TKI. Results: The median age of the patients who received reduced-intensity chemotherapy was 64.4 years, while that of the patients with intensive regimens was 47.5 years. There was no induction death in the reduced-intensity group, while nine patients died in the intensive therapy group. Major molecular response achievement tended to be higher in the intensive chemotherapy group than in the reduced-intensity group. More patients in the intensive chemotherapy group received allogeneic stem cell transplantation (allo-SCT). There was no statistically significant difference in long-term survival between the two groups in terms of relapse-free survival and overall survival rates. Conclusions When imatinib plus reduced-intensity therapy was used as a frontline treatment, there was no inferiority in obtaining complete remission compared to imatinib plus intensive chemotherapy or significant difference in long-term survival. Since imatinib plus reduced-intensity therapy has limitations in obtaining a deep molecular response, proceeding to allo-SCT should be considered.
