Background: Activation of the Wnt/β-catenin pathway is frequent in adrenocortical tumors (ACTs). This pathway and DAX1, a negative regulator of SF1 expression, control adrenal stem/progenitor cells, which can be involved in ACTs formation.Objective: To analyse the association between the Wnt/β-catenin pathway and the expression of a stem cell marker (NANOG), STAT3, DAX1 and SF1 in ACTs.Methods: Patients:...

Background: In total of 48,XXYY Syndrome occurs in 1:20.000–1:50.000 male births. It used to be considered as a variant of Klinefelter syndrome, but now it is considered as a distinct clinical and genetic entity with increased risks for congenital malformations, additional medical problems and more complex psychological and neurodevelopmental involvement. 48,XXYY Syndrome results from the fertilization of a normal female oocyte (Xm), with an aneuploid sperm (XpYpYp) produ...

Background: Cornelia de Lange (CdLS) syndrome (OMIM #122470) is a complex disease, characterized by distinctive facial features, failure to thrive, microcephaly, intrauterine growth retardation and anomalies in multiple organ systems. The complexity and severity of the endocrine commitment is variable. NIPBL, SMC1A, SMC3, RAD21 and HDAC8 genes, all involved in the cohesin pathway, have been identified to cause CdLS. There are few published studies on the endoc...

Introduction: Menarche is the time of first menstrual bleed and it occurs, on average, 2 to 2.5 years after the onset of puberty. Globally, the age of menarche had been reduced since the last century.Objective: To examine the evolution of the age of menarche over the last decades and inter-regional variability in an autonomous community located in northern Spain which is divided in eight health areas.<p class="abstex...

Objectives: We aimed to develop a non-invasive model for the detection of metabolic syndrome (MetS) in school children and adolescents.Methods: Participants were 7,330 children and adolescents aged 10–18 years attending schools in eight Chinese cities. Participants had anthropometry measured by research nurses and underwent fasting blood tests. MetS was defined as central obesity (waist-to-height ratio ≥0.46 f...

Background: Medulloblastoma is the most common malignant pediatric brain tumor. Although survival has improved with oncological therapy, late effects such as endocrine consequences are common, especially growth failure and thyroid dysfunction.Methods: Children diagnosed with medulloblastoma in a pediatric hospital between 2004 and 2014 were studied and followed until 2019. Statistical analysis was performed to estimate t...

Introduction:The incidence of obesity increases unstoppably in all populations and at all ages, and with it, the associated metabolic morbidity and mortality. The promotion of physical activity and a healthy diet are the fundamental elements to alleviate this situation. The objective of this study is to determine the relationship of physical activity and eating patterns with body composition, the degree of adiposity and certain metabolic risk factors.<p cl...

Background and Aims: Turner Syndrome (TS), 45X0, is the most common chromosomal pathology affecting females, occurring in 1:2500 to 1:5000 female infants. The typical phenotype includes short stature, gonadal dysgenesis leading to sexual infantilism, low-set ears, low rear hairlin, mamary hypertelorism, neck webbing, gothic palate, irregular rotation of the elbows, shield chest, shortening of the 4th metacarpal, low hairline, shortening of lower extremities, renal disorders a...

Background: Magnetic resonance imaging (MRI) of the hypothalamic-pituitary area is extremely useful in the investigation of patients with central diabetes insipidus (CDI) due to infiltrative processes.Objective: We aimed to associate pituitary stalk thickness with the etiology of CDI and hormone deficiencies.Method: A retrospective single-center study of 15 patients (four boys and 11 girls) with CDI was performed and clinical-epide...

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...
