Introduction: Prematurity, a worldwide health issue, is often associated with renal tubular immaturity leading to major salt loss, whose mechanisms remain poorly understood. Moreover, these premature infants are prone to develop hypertension early in adulthood.Objective: To study the ontogenesis of renal mineralocorticoid and glucocorticoid signaling pathways in preterm infants and to evaluate their respective role during neonatal adaptation and in the e...

Background/aim: Sorafenib® is a multi-kinase inhibitor and one of the few systemic treatment options for patients with advanced hepatocellular carcinomas (HCCs). Resistance to Sorafenib® develops frequently and could be mediated by the NAD dependent deacetylase sirtuin (SIRT) 1, a master regulator of cellular energy metabolism and stress responses. We aimed to find out if Sorafenib® treatment depends on changes in cellular NAD le...

Objective: The purpose of this study was to describe baseline data on etiological diagnosis of Disorders of Sex Development (DSD) in Kenyan children and adolescents.Methods: This retrospective study included 71 patients diagnosed with DSD who presented at ages 0–19 years from January 2008 to December 2015 at the Kenyatta National (KNH) and Gertrude’s Children’s (GCH) Hospitals.Results: Thirty-nine (54.9%) children ha...

Background: Vitamin D insufficiency is more frequent than expected also in Western Europe, however the relieve of a ‘health’ child with rickets is uncommon in Caucasians.Objective and hypotheses: Explain clinical severity by a genetic background.Method: We describe the clinical case of a 2.5-year-old girl with skeletal deformities. She was 86.5 cm (10° Cent), 12.5 kg (3–10° Cent); PH1B1. She showed typical ...

Background: T1DM incidence in children varies across regions and countries, showing a continue rise Worldwide.Objective and hypotheses: To determine the incidence of T1D in Chilean children under 20 years between 2006 and 2012.Method: We reviewed mandatory notifications of T1D (GES Program) in Chile’s public health system in population younger than 20 years between 2006 and 2014. Data were obtained from the Department of Infor...

Background: Small for gestational age (SGA) children, especially those with postnatal catchup growth, have increased risk of insulin resistance and adult metabolic diseases. Adipokines produced by adipose tissue play crucial role in fetal growth and early postnatal life. Low adiponectin (adipokine) is marker of insulin resistance.Objective: To evaluate adiponectin levels in term SGA at 15–18 months age and its relationship with postnatal catchup gro...

Background: Isolated GH deficiency type II (IGHD II), the autosomal-dominant form of GH deficiency, is mainly caused by specific splicing mutations in the human GH (hGH) gene (GH-1). These mutations, occurring in and around exon 3, cause complete exon 3 skipping and produce a dominant-negative 17.5-kDa GH isoform that reduces the accumulation and secretion of wt-GH.Objective and hypotheses: As the severity of IGHD II inversely correlate...

Background: Small-for-gestational-age (SGA) newborn infants (NB) may present long-term comorbidities influencing their metabolism, growth and/or development. Although their serum proteome is unknown, altered expression of the proteome profile may provide information on their physiopathology and lead to the discovery of biomarkers for postnatal complications.Aim: To detect changes in the serum proteome in SGA-NB vs adequate-for-gestational-age (AGA) newbo...

Background: overexpression of the oncogene Yes-associated protein 1 (YAP1), a Hippo pathway target, associates with increased cell proliferation in some human cancers. There is not data on adrenocortical tumors (ACT). YAP1 is a potential target of Wnt/β-catenin pathway, which plays an important role in ACTs.Objective and hypotheses: to evaluate the role of YAP1 and its interaction with the Wnt/β-catenin pathway in ACT.Met...

Background and Aim: Pediatric patients with germline mutations in the tumor suppressor gene PTEN (PTEN hamartoma tumor syndrome, PHTS) frequently develop lipomas. PTEN antagonizes phosphoinositide 3-kinase (PI3K) signaling, which can induce adipogenesis upon activation through insulin. The PI3K downstream target AKT can deactivate FOXO1 via phosphorylation, initiating the expression of the lipogenesis activating transcription factor SREBP1. To study t...
