Deficiency of pregnancy-associated plasma protein-A2 (PAPP-A2), a protease that regulates IGF-1 availability, causes postnatal growth failure and changes in bone size and density in humans and mice. The present study aimed to determine the effects of daily administration (from PND5 to PND35) of recombinant murine (rm) PAPP-A2, in comparison to rmGH and rmIGF1, on mouse auxology and bone microarchitecture in homozygous Pappa2 knock-out (ko/ko) mice of both sexes. Hormone treatm...

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...

Objective: To present a patient with hypercalcemia caused by a parathyroid adenoma and a deletion of the VDR gene.Case clinic: The case is that of a 13-year-old male who presented with hypercalcemia, muscle weakness, nephrocalcinosis, two pathological fractures and a family history of nephrocalcinosis. Physical examination was unremarkable, except the presence of a fracture of the left femur. Laboratory findings: Total s...

Background: Physical activity (PA) has been conclusively shown to reduce the incidence of diabetes in prior research. A 2,000 steps/day increment yielded hazard ratio (HR) 0.88 for incidence of diabetes 95% CI 0.78–1.00; P=0.046 (Garduno, 2022). Despite this, the role of different factors associated with higher adolescent after-school PA is understudied after the coronavirus pandemic, during which a greater proportion of parents worked remotely....

Novel CNS imaging techniques is a fast advancing field with frequent new developments in scanner’s hardware, protocols, clinical indications, and post-processing techniques. These techniques are designed to focus on the assessment of functional tissue characteristics, such as neuronal activity (functional MRI- fMRI), microstructural properties (diffusion tensor imaging-DTI) and tissue perfusion (DSC perfusion, ASL). fMRI reveals brain activation during performance of beha...

High-throughput biomolecular (omic) analyses enabled the simultaneous quantification of hundreds or thousands of transcripts, proteins, metabolites in a biological system, contributing to the identification of discriminatory multi-component molecular profiles of a pathophysiology. Molecular quantities being interconnected, even subtle differences in one can carry significance if viewed in the context of the observed changes in the rest of the molecules. We can now view molecul...

Background: GH therapy for GH deficient (GHD) children in Russia is fully state funded as part of the ‘Seven high expenditure diseases’ (7HED) federal program. Thus, it is important to thoroughly understand the disorder, including its epidemiology. In Russia, there are two parallel functioning registries: the official federal medical statistics (OFMS) which provides purely statistical information and the 7HED registry which must contain a patient’s data to make ...

Objective: To describe clinical, laboratory and genetic characteristics of 42 short children from 34 consanguineous Turkish families.Design: Descriptive case series.Methods: After collecting clinical information, DNA samples were analysed in three European laboratories. In 18 children (12 families) suspected of a genetic defect in the growth hormone (GH)-insulin-like growth factor ...

Introduction: The 46,XX testicular disorder of sex development (DSD) is a rare genetic condition and clinical phenotype shows complete sex reversal from female to male. The sex-determining region Y (SRY) gene can be identified in most 46,XX testicular DSD patients, but approximately 20% of patients are SRY-negative. We report a 1.3 -year old SRY/negative 46,XX boy with complete sex reversal caused by SOX3 duplication.Case report:...
