However, no simple quantitative indicator can estimate the risk of hypokalemia at treatment initiation. This multicenter retrospective cohort study enrolled patients hospitalized for hyperglycemic crises who received CII. Clinical data available at CII initiation were collected. Machine-learning techniques were primarily employed for feature selection and model comparison to develop a simple, clinically interpretable prediction model. A logistic regression-based indicator was constructed using the most contributory variables and validated internally and externally. Hypokalemia was defined as a serum potassium level <3.5 mmol/L. The model-building and external validation cohorts included 99 and 55 patients, respectively. Among multiple candidate models, a lightweight logistic regression model using only two variables, serum potassium level and insulin infusion rate per body weight, was selected for clinical applicability. In internal validation, the model demonstrated good discriminative performance (receiver operating characteristic-area under the curve [ROC-AUC] 0.821). When applied to the external validation cohort, the ROC-AUC was 0.655, and accuracy decreased slightly. A lower threshold may increase sensitivity in screening, whereas a higher threshold may improve specificity. In conclusion, this study presents a simple and clinically applicable indicator for predicting CII-related hypokalemia using only two routinely available variables at treatment initiation. This model supports individualized electrolyte monitoring during the acute management of hyperglycemic crises. Additionally, it may facilitate safer and more efficient clinical decision-making without reliance on complex algorithms.</p>","PeriodicalId":11631,"journal":{"name":"Endocrine journal","volume":" ","pages":"1037-1044"},"PeriodicalIF":2.5,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13572949/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147962581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Comprehensive systemic amyloidosis screening, the first systematic evaluation reported for this entity, excluded systemic disease. Following surgical debulking with extensive residual disease, postoperative cabergoline treatment resulted in a reduction in the PRL (4,700→927 ng/mL). Given the presence of amyloid-associated dopamine resistance, cabergoline was discontinued, and radiotherapy (RT) (45 Gy) was initiated to control the amyloid burden, followed by temozolomide. Based on evidence from other malignancies suggesting RT-mediated amyloid reduction, cabergoline was reintroduced postradiotherapy without paradoxical tumour growth. Concurrent cabergoline-temozolomide therapy, a novel approach that differs from conventional sequential protocols, achieved a dramatic response: 93.4% prolactin reduction (10,320→677 ng/mL) and 52.4% tumour volume reduction.

Elevated intracellular calcium in adrenal zona glomerulosa cells acts as a key signal for aldosterone biosynthesis, thereby promoting excessive aldosterone secretion and contributing to the development of hypertension. The PPP2R5D gene encodes a regulatory subunit of protein phosphatase 2A (PP2A). Mutations in this gene may disrupt the regulatory function of PP2A, impairing the dephosphorylation of key neuroproteins and consequently affecting neural signal transduction and brain function.

This study aimed to investigate whether the balance between cellular integrity (phase angle [PhA]) and metabolic load (body fat mass [BFM]) is more clinically relevant to glycemic control than SMM-based profiling in patients with T2DM. In this cross-sectional study of 622 patients, participants were stratified into four groups based on sex-specific medians of PhA and BFM, and similarly for SMM and BFM. Multivariate logistic regression evaluated associations with glycemic targets (HbA1c <8.0% and <7.0%), adjusting for confounders. Sensitivity analyses utilized continuous Z-scores and interaction terms. High-PhA/High-BFM and High-PhA/Low-BFM groups showed significantly higher odds of HbA1c <8.0% compared with the Low-PhA/High-BFM reference group (adjusted odds ratio [OR] 2.05, 95% confidence interval [CI] 1.22-3.44; OR 2.10, 95% CI 1.21-3.64, respectively). Conversely, SMM/BFM combinations showed no significant associations. Neither profile was significantly associated with the stricter HbA1c <7.0% target. In continuous models, the PhA × BFM interaction was significantly associated with achievement of HbA1c <8.0% (p = 0.025), whereas SMM × BFM interaction was not. In conclusion, the PhA/BFM interplay shows a clearer association with glycemic control than SMM/BFM profiling in T2DM.

Primary mouse hepatocytes and HepG2 cells were treated with IL-1β. ABCA1 expression was assessed by Western blotting and RT-qPCR, and ABCA1 promoter activity was examined using luciferase reporter assays with inhibitors targeting phosphoinositide 3-kinase (PI3K), p38 mitogen-activated protein kinase (p38 MAPK), or an H-89-sensitive pathway.

IL-1β decreased ABCA1 protein and mRNA expression in a dose- and time-dependent manner and suppressed ABCA1 promoter activity.

Representative immunoblotting showed that IL-1β enhanced p38 MAPK phosphorylation, whereas SB203580 attenuated this response.
