To determine the basis for perinatal nutritional mismatch causing metabolic dysfunction associated steatotic liver disease (MASLD) and diabetes mellitus, we examined adult phenotype, hepatic transcriptome, and pancreatic β-islet function. In prenatal caloric restricted rat with intrauterine growth restriction (IUGR) and postnatal exposure to high fat with fructose (HFhf) or high carbohydrate (RC), we investigated male and female IUGR-Hfhf and IUGR-RC, versus HFhf and CON offspring. Males more than females displayed adiposity, glucose intolerance, insulin resistance, hyperlipidemia, hepatomegaly with hepatic steatosis.

However, whether peripheral neuroimmune interactions orchestrate endocrine system functions remains unexplored. After fasting, mice lacking type 2 innate lymphoid cells (ILC2s) displayed disrupted glucose homeostasis, impaired pancreatic glucagon secretion, and inefficient hepatic gluconeogenesis.

Recurrent acute pancreatitis (RAP) affects 15-36% of children with acute pancreatitis (AP) and may progress to chronicity. To determine the etiology and evolution of RAP, a descriptive retrospective cohort study was conducted in patients aged 1-18 years. Twelve patients with RAP were included out of 79 with AP, and demographic, etiological, clinical, analytical, and imaging data were collected.

Introduction: The impact of endoplasmic reticulum (ER) stress in tumor-associated cells, such as cancer associated fibroblasts (CAFs), immune cells and endothelial cells, on patient outcomes in clinical specimens have not been examined. For the first time, we characterized the expression and spatial locations of ER stress markers, BiP and CHOP, in tumor-associated cells and assessed their prognostic significance in a panel of pancreatic ductal adenocarcinoma (PDAC) patient samples.
Methods: Multiplex immunofluorescence was performed on tumor microarrays and images were analyzed using HALO AI software.
Evaluation of iodine and selenium level and thyroid functions in patients with cystic fibrosis.

Objectives: There is limited research on thyroid function in pediatric patients with cystic fibrosis (pwCF). This study aimed to determine the frequency of thyroid dysfunction in children and adolescents with CF and to evaluate iodine deficiency and selenium status in pwCF.
Methods: Sixty-two CF patients and 62 control subjects were evaluated.
