Background and Objectives:
Evidence remains limited on the real-world prescription of very low-dose oral anticoagulation among frail patients with atrial fibrillation (AF). We described the practice patterns, effectiveness, and safety of very low-dose edoxaban (15 mg once daily).
Methods:
Patients with AF prescribed edoxaban 15 mg once daily in 2 tertiary hospitals between 2016 and September 2022 were included. Baseline clinical characteristics and clinical outcomes of interest were thromboembolic and bleeding events.
Results:
A total of 674 patients were included (mean age 78.3±9.1, 49.7% aged ≥80 years, 49.3% women, median follow-up 1.0±1.2 years). Mean CHA 2 DS 2 -VASc score was 3.9±1.6, and the modified HAS-BLED score was 2.0±1.1. Between 2016 and 2022, the number of very lowdose edoxaban prescriptions increased. The main reasons for the prescription of very lowdose were low body weight (55.5% below 60 kg), anaemia (62.8%), chronic kidney disease (40.2%), active cancer (15.3%), concomitant anti-platelet use (26.7%), and prior major bleeding (19.7%). During a median follow-up duration of 8 (interquartile range 3–16) months, overall thromboembolic and bleeding events occurred in 16 (2.3%) and 88 (13.1%) patients, respectively. Compared to the expected event rates on the established risk scoring systems, patients receiving very low-dose edoxaban demonstrated a 61% reduction in ischemic stroke, a 68% reduction of ischemic stroke/transient ischemic attack/systemic embolism, whereas a 49% increase in major bleeding.
Conclusions
The prescription of very low-dose edoxaban was increased over time, attributable to various clinical factors. The use of very low-dose edoxaban reduced the expected risk of thromboembolic events.

Since the role of the liver in metabolic dysfunction, including type 2 diabetes mellitus, was demonstrated, studies on non-alcoholic fatty liver disease (NAFLD) and metabolic dysfunction-associated fatty liver disease (MAFLD) have shown associations between fatty liver disease and other metabolic diseases. Unlike the exclusionary diagnostic criteria of NAFLD, MAFLD diagnosis is based on the presence of metabolic dysregulation in fatty liver disease. Renaming NAFLD as MAFLD also introduced simpler diagnostic criteria. In 2023, a new nomenclature, steatotic liver disease (SLD), was proposed. Similar to MAFLD, SLD diagnosis is based on the presence of hepatic steatosis with at least one cardiometabolic dysfunction. SLD is categorized into metabolic dysfunction-associated steatotic liver disease (MASLD), metabolic dysfunction and alcohol-related/-associated liver disease, alcoholrelated liver disease, specific etiology SLD, and cryptogenic SLD. The term MASLD has been adopted by a number of leading national and international societies due to its concise diagnostic criteria, exclusion of other concomitant liver diseases, and lack of stigmatizing terms. This article reviews the diagnostic criteria, clinical relevance, and differences among NAFLD, MAFLD, and MASLD from a diabetologist’s perspective and provides a rationale for adopting SLD/MASLD in the Fatty Liver Research Group of the Korean Diabetes Association.

OBJECTIVES:
Long-term care facilities (LTCFs) are communal environments for patients with chronic diseases or older adults, making them particularly susceptible to significant harm during infectious disease outbreaks. Nonetheless, LTCFs have historically been subject to less stringent infection prevention and control (IPC) mandates. This study aimed to assess the current state of LTCFs and to develop an IPC system tailored for these facilities following the coronavirus disease 2019 (COVID-19) pandemic.
METHODS:
We conducted an online survey of 11,366 LTCFs in Korea from December 30, 2022 to January 20, 2023, to evaluate the components of IPC in LTCFs. The infectious diseases targeted for IPC included COVID-19, influenza, and scabies. Additionally, we compared institution-based and home-based long-term care insurance facilities.
RESULTS:
Overall, 3,537 (31.1%) LTCFs responded to the survey, comprising 1,819 (51.4%) institution-based and 1,718 (48.6%) home-based facilities. A majority (87.4%, 2,376/2,720) of these facilities experienced COVID-19 outbreaks. However, only 42.2% of home-based facilities, in contrast to 90.6% of institution-based facilities, were equipped to manage concurrent COVID-19 cases. Similarly, while 92.1% of institution-based facilities were capable of managing influenza, only 50.5% of home-based facilities could do the same. The incidence of scabies was significantly higher in institution-based facilities than in home-based ones (26.1 vs. 4.3%). Additionally, 88.7% of institution-based facilities managed scabies cases effectively, compared to only 42.1% of home-based facilities.
CONCLUSIONS
Approximately half of the LTCFs had a basic capacity to respond to infectious diseases. However, there were differences in response capabilities between institution-based facilities and home-based facilities.

Objectives:
. This study evaluates the enduring efficacy and patient satisfaction of dupilumab with interdose interval adjustments based on the Sino-Nasal Outcome Test (SNOT-22) in chronic rhinosinusitis with nasal polyps (CRSwNP).
Methods:
. A retrospective analysis was conducted on 44 patients who had been treated with dupilumab for over 6 months. This study targeted individuals diagnosed with CRSwNP according to the 2020 edition of the European Position Paper on Rhinosinusitis and Nasal Polyps Criteria. The treatment involved an add-on dupilumab regimen, where the interdose interval was adjusted based on the SNOT-22 scores. Dosage adjustments were made such that patients with initial SNOT-22 scores greater than 40 were tapered to a target level of 20 or less. Similarly, for patients with initial scores of 40 or less, the treatment aimed for an improvement of 50% or more. At each visit, the effectiveness of the treatment was evaluated using SNOT-22, nasal polyp scores (NPS), and a subjective satisfaction questionnaire adapted from the Treatment Satisfaction Questionnaire for Medication (TSQM v.1.4).
Results:
. The adjustment of the interdose interval for dupilumab based on SNOT-22 scores demonstrated sustained improvements in patients’ subjective symptoms, satisfaction, and NPS. The mean (standard deviation) SNOT-22 scores significantly decreased from 46.04 (22.30) to 14.72 (13.66) over 6 months (P<0.001). Similarly, NPS scores improved from 3.20 (2.24) to 1.72 (1.46) within the same period (P<0.001). Satisfaction scores, ranging from 0 to 5, consistently remained above 3.5 for up to 6 months (P=0.166). Additionally, there was a significant correlation between the improvement in the nasal symptom domain of the SNOT-22 scores and higher satisfaction scores.
Conclusion
. Adjusting dupilumab dosing intervals based on SNOT-22 scores from the outset resulted in sustained efficacy and patient satisfaction in Korean patients with CRSwNP. This approach will meaningfully assist clinicians in determining the optimal dupilumab dosing interval.
