Background/Aims: Chronic kidney disease (CKD) is a significant health problem worldwide, and identifying risk factors for CKD is crucial. We investigated the association between steatotic liver disease (SLD) and the incidence of CKD. Methods: This longitudinal cohort study involved 70,361 adults who did not have CKD at baseline and who underwent at least two health checkups. SLD status was assessed via ultrasonography. The severity of SLD was determined using the Fibrosis-4 score. CKD was defined as an estimated glomerular filtration rate <60 mL/min/1.73 m 2 . Results: Over 475,835 person-years (mean 6.8 years), 2,723 participants developed CKD.The adjusted hazard ratio (aHR) for development of CKD in participants with SLD compared to those without SLD was 1.17 (95% confidence interval [CI], 1.08 to 1.27), with the risk increasing with SLD severity. The aHR (95% CI) for incident CKD was 0.84 (0.51 to 1.37) for cryptogenic SLD, 1.25 (1.16 to 1.36) for metabolic dysfunction-associated SLD (MASLD), and 1.32 (1.01 to 1.73) for metabolic dysfunction-associated alcoholic liver disease (MetALD) compared with participants without SLD. Within these SLD subclassifications, the risk of CKD development was increased as disease severity advanced. Conclusions SLD was linked to a higher incidence of CKD, with the CKD risk increasing sequentially from cryptogenic SLD to MASLD and MetALD. Advanced fibrosis in each SLD subclassification further increases the risk of CKD. Stratifying SLD according to metabolic dysfunction, significant alcohol intake, and fibrosis severity may help identify and monitor individuals at high risk of developing CKD.

Metabolic dysfunction-associated steatotic liver disease (MASLD) is a common chronic liver disease that can progress from simple steatosis to metabolic dysfunction-associated steatohepatitis (MASH), advanced fibrosis or cirrhosis, and hepatocellular carcinoma. MicroRNAs (miRNAs) are increasingly recognized as central post-transcriptional regulators of lipid metabolism, insulin resistance, inflammatory signaling, fibrogenesis, and exosome-mediated intercellular communication. This review critically reassesses key miRNA axes implicated in MASLD progression, focusing on mechanistically supported examples (miR-34a, miR-21, miR-122, the miR-29 family, miR-20b, and miR-93), tissue miRNA isoforms (isomiRs), circulating miRNA biomarkers, and therapeutic translation. Recent studies support the diagnostic relevance of selected circulating miRNA panels and hepatic isomiR landscapes; however, current evidence remains insufficient to position miRNAs as standalone replacements for established noninvasive tests or liver biopsy. Liver-directed oligonucleotide delivery platforms continue to advance; however, MASLD-specific miRNA drug development remains largely preclinical, with only limited exploratory early clinical activity. Importantly, the rapidly evolving therapeutic landscape, which currently includes Food and Drug Administration-approved therapies, some of which have been granted accelerated approval, for adults with noncirrhotic steatohepatitis/ MASH and F2–F3 fibrosis, reshapes how miRNA therapeutics should be positioned: not as broad substitutes, but as mechanism-informed, patient-stratified, and potentially combinationbased approaches. Overall, miRNA and isomiR biology provide a compelling framework for precision diagnostics and next-generation therapeutic design in MASLD, provided that mechanistic rigor, preanalytical standardization, and clinically meaningful endpoints are maintained.

Olanzapine is a second-generation antipsychotic drug associated with the development of type 2 diabetes. However, the development and remission of diabetes with glutamic acid decarboxylase (GAD) antibody (Ab) positivity related to olanzapine treatment have not been reported. Here, we present the case of a 33-year-old man taking olanzapine who was diagnosed with diabetes with GAD Ab positivity complicated by diabetic ketoacidosis (DKA). After discontinuation of the drug and tight glycemic control, his diabetes remitted, and the GAD Ab became negative spontaneously after 18 months. The classification of diabetes is challenging because of overlapping autoimmune and metabolic features. Olanzapine may have contributed to pancreatic β-cell apoptosis, which could potentially trigger autoimmunity and the development of type 1 diabetes-like features (DKA as the initial presentation, a low C-peptide level, and GAD Ab positivity). The rapid amelioration of hyperglycemia and weight reduction may be responsible for the remission of diabetes after the discontinuation of olanzapine.

In light of the burgeoning successes of cancer immunotherapy, glioblastoma (GBM) remains refractory due to an immunosuppressive microenvironment originating from its molecular heterogeneity. Thus, identifying promising therapeutic targets for treating GBM and discovering methodologies to effectively regulate them is still a tremendous challenge. Here we describe photodynamic protein tyrosine phosphatase 1B (PTP1B) proteolysis mediated by a proteolysis-targeting chimera (PROTAC) nanoassembly. The PTP1B-targeting PROTAC is conjugated with a photosensitizer via a cathepsin B (Cat B)-cleavable peptide, which spontaneously forms nanoassemblies due to intermolecular π-π stacking interactions. In GBM models, PROTAC nanoassemblies significantly accumulate in the tumor region across the disrupted blood-brain barrier (BBB), triggering a burst release of the photosensitizer and active PROTAC by Cat B-mediated enzymatic cleavage. Upon laser irradiation, photodynamic therapy (PDT) synergizes with PROTAC-mediated PTP1B proteolysis to induce potent immunogenic cell death (ICD) in tumor cells. Subsequently, persistent PTP1B degradation by nanoassemblies in Cat B-overexpressed intratumoral T cells downregulates exhaustion markers, reinvigorating their functionality. These sequential processes of photodynamic PTP1B proteolysis ultimately augment T cell-mediated antitumor immunity as well as protective immunity, completely eradicating the primary GBM and preventing its recurrence. Overall, our findings underscore the therapeutic potential of combining PDT with PROTAC activity for GBM immunotherapy.

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.

Background/Aims: This study aimed to evaluate the performance of the Model for End-Stage Liver Disease (MELD) 3.0 for predicting mortality and liver-related complications compared with the Child-Pugh classification, albumin-bilirubin (ALBI) grade, the MELD, and the MELD sodium (MELDNa) score. Methods: We evaluated a multicenter retrospective cohort of incorporated patients with cirrhosis between 2013 and 2019. We conducted comparisons of the area under the receiver operating characteristic curve (AUROC) of the MELD3.0 and other models for predicting 3-month mortality. Additionally, we assessed the risk of cirrhosis-related complications according to the MELD3.0 score. Results: A total of 3,314 patients were included. The mean age was 55.9±11.3 years, and 70.2% of the patients were male. Within the initial 3 months, 220 patients (6.6%) died, and the MELD3.0had the best predictive performance among the tested models, with an AUROC of 0.851, outperforming the Child-Pugh classification, ALBI grade, MELD, and MELDNa. A high MELD3.0score was associated with an increased risk of mortality. Compared with that of the group with a MELD3.0 score <10 points, the adjusted hazard ratio of the group with a score of 10–20 pointswas 2.176, and that for the group with a score of ≥20 points was 4.892. Each 1-point increase inthe MELD3.0 score increased the risk of cirrhosis-related complications by 1.033-fold. The risk of hepatorenal syndrome showed the highest increase, with an adjusted hazard ratio of 1.149, followed by hepatic encephalopathy and ascites. Conclusions The MELD3.0 demonstrated robust prognostic performance in predicting mortality in patients with cirrhosis. Moreover, the MELD3.0 score was linked to cirrhosis-related complications, particularly those involving kidney function, such as hepatorenal syndrome and ascites.

Progesterone hypersensitivity is mediated by type I, III, and IV hypersensitivity reactions to endogenous or exogenous progesterone, involving autoimmune mechanisms in females of reproductive age. It presents with a range of dermatologic manifestations, most commonly urticaria, angioedema, eczema, and maculopapular rashes. Systemic and severe symptoms, such as generalized erythema multiforme or lesions resembling severe cutaneous adverse reactions, have rarely been reported. We describe a case of a 42-year-old woman who developed drug reaction with eosinophilia and systemic symptoms (DRESS) following exogenous progesterone therapy administered for assisted reproduction. She received high-dose subcutaneous progesterone and vaginal tablets. Despite this being her first procedure, she achieved pregnancy. However, at 8 weeks of gestation and during the third month of progesterone treatment, she developed generalized erythema multiforme, pruritus, and high-grade fever. Her laboratory findings showed increased blood eosinophil counts and inflammatory markers. After oral corticosteroid (OCS) treatment for several weeks, her skin lesions were partially improved. However, after tapering of OCS, her skin lesions were aggravated with increased blood eosinophil counts. Despite daily OCS (prednisolone, 12.5–60 mg/day) treatment after childbirth, her skin symptoms and eosinophilia persisted. Reslizumab treatment was also attempted, but only the eosinophilia resolved. These clinical findings were much improved after Janus kinase (JAK) inhibitor (upadacitinib 15 mg/day) treatment; consequently, OCS was stopped. Here, we report a case of relapsing DRESS triggered by exogenous progesterone, which has been controlled by JAK inhibitor treatment.
