Glucokinase activators (GKAs) are new medications that target glucokinase (GK) to increase glucose utilization in both the pancreas and liver. Its effectiveness and safety are inconsistent across various doses and types. The meta-analysis assessed the effectiveness and safety of GKAs in T2DM on glycemic control (hemoglobin A1c [HbA1c], fasting plasma glucose [FPG], postprandial plasma glucose [PPG]) as well as metabolic parameters (lipids, body weight, safety outcomes) stratified by dosage, type, and intervention time. The study involved a comprehensive analysis of 3,854 participants drawn from 11 randomized controlled trials (RCTs). Standardized mean differences (SMDs) and risk ratios (RRs) were computed employing random-effects models, alongside conducting sensitivity and subgroup analyses. GKAs effectively lowered HbA1c and PPG, especially high-dose (HbA1c: SMD = -0.43, 95% CI: -0.62 to -0.24) and dual-acting GKAs. Medium and high-dose GKAs were associated with increased risk of hypoglycemia (RR = 1.50; 1.63). At 24 weeks, GKAs led to increases in triglycerides, body weight, and liver enzymes, with the majority of these effects subsiding by 52 weeks. GKAs provide favorable glycemic control but carry dose-dependent concerns. While dual-acting GKAs demonstrate impressive efficacy, hepatoselective GKAs reveal improved safety. There exists a pressing need for further longitudinal studies and customized treatment approaches concerning the utilization of GKAs.PROSPERO registration: CRD42020188517.</p>","PeriodicalId":11631,"journal":{"name":"Endocrine journal","volume":" ","pages":"1099-1114"},"PeriodicalIF":2.1,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12510786/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144575080","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}

Anthropometric parameters and treatment protocols were evaluated based on medical records. Individuals with background disorders or impaired growth were excluded from the study. Associations between anthropometric parameters during chemotherapy and height standard deviation scores (height-SDS) at the current visit were investigated. The results are expressed as the median (interquartile range). Seventy-three individuals (males, N = 44) were included in the study.

Herein, we report a unique case of SACC with characteristics distinct from those previously documented. A 66-year-old man presented with uncontrolled hypertension, night sweats, exertional dyspnea, and palpitations. Imaging revealed an 11 cm mass in the left adrenal gland. Laboratory results indicated hypokalemia with suppressed plasma renin and aldosterone levels and the presence of mineralocorticoid intermediates, notably elevated deoxycorticosterone (DOC), detected via LC-MS/MS. The patient underwent a left adrenalectomy. Histologically, the tumor consisted solely of spindle cells without the typical adrenocortical carcinoma components. Immunohistochemical analysis demonstrated partial positivity for steroidogenic enzymes, including 3β-hydroxysteroid dehydrogenase, cytochrome P450 family 21 subfamily A member 2 (CYP21A2) and cytochrome P450 family 11 subfamily B member 1 (CYP11B1). This finding was consistent with RNA expression analysis, supporting the synthesis of mineralocorticoid intermediates within the tumor. However, the discrepancy between the measured steroid intermediate metabolites and enzyme expression patterns in the tumor, as indicated by immunostaining and mRNA levels, suggests that the steroid production pathway in this tumor remains partially unclear.

Metabolic zonation, a key feature of liver function, has been studied for decades.

However, traditional methods have struggled to reveal the spatial regulation of gene expression and signaling within these zones. Recent advances in single-cell and spatial omics technologies now allow detailed analysis of gene expression, signaling pathways, and cell-cell interactions with spatial resolution, providing new insights beyond classical models. Metabolic zonation research is rapidly advancing, and the concept of immune zonation, describing the spatial distribution of immune cells, has gained attention for its role in liver metabolism. These findings have improved our understanding of metabolic changes in conditions like fatty liver disease and diabetes.

Hormones associated with oncologic metabolic emergency include parathyroid hormone and parathyroid hormone-related peptide (PTHrP), but 1,25-dihydroxyvitamin D (1,25(OH)₂D) is rarely the cause. We report the case of an 87-year-old man with hypercalcemic crisis owing to 1,25(OH)₂D overproduction from a high-grade intranasal non-intestinal-type adenocarcinoma. 1,25(OH)₂D and corrected Ca levels normalized after tumor resection and did not re-elevate subsequently. Serum PTH was suppressed and PTHrP not detected, suggesting the hypercalcemia was not due to the PTH pathway. Immunohistochemistry for CYP27B1, a key enzyme that converts 25-hydroxyvitamin D (25(OH)D) to 1,25(OH)₂D, showed positivity in the cytosol of about 20% of tumor cells, but only about 1% of the macrophages.
