Introduction: Tandem Control-IQ and Minimed 780G are advanced hybrid closed-loop pumps (HCL) that began to use in adults and children in our hospital in 2021. These systems are made up of a continuous interstitial glucose monitoring (CGM) system, the insulin infuser, and the algorithm that automatically adjusts insulin delivery based on real-time glucose levels. Patients only require carbohydrate counting to calculate boluses. The aim of our study was to compa...

Background: Endoplasmic reticulum (ER) is the site where proteins are folded in the cell. Metabolic stress alters ER homeostasis and activates the unfolded protein response (UPR), which contributes to the development of insulin resistance and metabolic syndrome.Objective and hypotheses: To longitudinally evaluate liver UPR and its functional consequences in an animal model of IUGR followed from birth to adulthood.Method: On day 19 ...

Background: Endoplasmic reticulum (ER) is the site where proteins are folded. Perturbation of ER homeostasis activates a set of ER-to-nucleus signaling reactions known as the unfolded protein response (UPR). Metabolic stress causes UPR activation which contributes to the development of insulin resistance and metabolic syndrome. As UPR can be activated by nutrient and oxygen starvation, we postulated that intrauterine growth restriction may trigger UPR signaling and thereby con...

Background: Human placenta exhibits a specific miRNA expression pattern. Some of these miRNAs are dysregulated in pregnancy disorders like preeclampsia and intrauterine growth restriction (IUGR), and are potential biomarkers for these pathologies. No studies have been performed in maternal obesity.Objective and hypotheses: (1) Define the placental miRNA profile in pregnant women with: a) pre-pregnancy (preOB) or gestational obesity (gestOB), b) gestation...

Background: Gestational obesity has not only adverse effects on the mothers’ health but also on the developing fetus. Newborns of obese pregnant women have increased birth weight and increased risk for obesity and associated diseases in adulthood. The mechanisms by which maternal nutrition induce these changes in the offspring may involve microRNAs (miRNAs) regulation.Aims and objectives: To study the associations between circulating miRNAs altered ...

Background: miRNAs are valuable circulating biomarkers and therapeutic targets for metabolic diseases. A differential pattern of miRNAs has been described in pregnant women with preeclampsia or gestational diabetes; however, it is unknown whether maternal obesity affects the profile of circulating miRNAs.Aims and objectives: To define the circulating pattern of miRNAs in pregestational and gestational obesity; and to explore their associations with mater...

Background: Prenatal dexamethasone (DXM) treatment has been proposed to prevent genital virilization in girls with congenital adrenal hyperplasia (CAH), however its safety has been questioned for potential adverse effects on the foetus and the mother.Objective and hypotheses: To analyse clinical practice and prenatal treatment experience with DXM during pregnancy at risk of having her daughters with severe CAH.Method: An online sur...

Background: An activation cascade of specific genes sets up the initiation of sex determination leading in males to testes formation and synthesis of testicular hormones. Disruption of this gene cascade may cause a spectrum of 46,XY disorders/differences of sex development (DSD) phenotypes. Here we describe for the first time two sisters suffering from 46,XY DSD, who by whole exome sequencing revealed to carry a X-linked mutation in the StAR-related lipid transfer domain prote...
