Cracking the pituitary stem cell code across life using single-cell transcriptomics and organoid models

Vankelecom Hugo

The pituitary gland dynamically remodels during key timepoints of life to meet the prevailing endocrine demands of the organism. Mechanisms underlying this plasticity remain poorly understood. In particular, it is not clear how the pituitary stem cells are involved and biologically behave during pituitary remodeling processes. Indeed, pituitary stem cells remain highly enigmatic regarding cellular complexity, regulatory circuits, niche make-up and functional role. In our studi...

Effects of Zinc, Magnesium and Vitamin B6 (ZMA) Supplementation on Serum IGF-I, IGFBP-3 and Testosterone Concentrations in Young Athletes

Cerqueira Henrique , Tourinho Filho Hugo , Martinelli Jr Carlos

Background: The GH-IGF system plays an important role in strength gain. Some studies suggest that Zinc, Magnesium and Pyridoxine (ZMA) supplementation could increase GH/IGF and testosterone levels in young subjects. This hypothetical increase could lead to significant changes in body composition. ZMA is a very popular supplement, easily found in specialty stores, and it is presumed to increase GH, IGF-I and testosterone levels. However, studies are divergent regarding its effi...

Comparison of Densitometric Aspects during the Transition Period in Patients with Congenital and Acquired Pituitary Deficiency: First Argentine Experience

Boquete Hugo , Boquete Carla , Ruibal Gabriela , Suarez Martha , Azaretzky Miriam , Nuñez Chavarria Eleonora , Sequera Ana , Fideleff Hugo

The transition phase is the period from the end of puberty until achievement of full adult maturity. We report the results from 45 patients with pituitary deficiency (15-24.9years), 28 (16males) with congenital insufficiency (G1) and 17 (10males) with acquired disease (G2), evaluated at the end of GH therapy. All cases had confirmed GH deficiency; 89.2 % of cases from G1 had multiple pituitary deficiencies (TSH 23/28, LH/FSH 19/28, ACTH 15/28 and Prolactin 3/28), 94.1 &#37...

Nonclassic Congenital Adrenal Hyperplasia and Functional Ovarian Hyperandrogenism Diagnosed During the Transition Period: Differences in Clinical, Hormonal and Metabolic Aspects

Boquete Hugo , Azaretzky Miriam , Llano Miriam , Jose Iparraguirre Maria , Schwartz Nadia , Suarez Martha , Boquete Carla , Sobrado Patricia , Fideleff Hugo

Introduction: Hyperandrogenism is a common presenting complaint during the transition period; however, clinical, hormonal and metabolic parameters in these patients have not been yet adequately characterized.Objective: To evaluate the disease-related history, clinical presentation and biochemical parameters in patients diagnosed during this period with nonclassic congenital adrenal hyperplasia (NCCAH) due to 21α hydroxylase deficiency and patients w...

Metabolic Syndrome in Prepubertal Obese Children: Inclusion of the Triglyceride/Hdl Ratio as an Alternative Diagnostic Criterion

Boquete Carla , Jesica Baran , Yuseff Fernanda Alvarez , Suarez Martha , Fideleff Gabriel , Azaretzky Miriam , Aranguren Marcela , Fusero Mariela , Ruibal Gabriela , Fideleff Hugo , Boquete Hugo

Background: Although a large number of publications show a high prevalence of Metabolic Syndrome (MS) during childhood, to date, there is no uniform definition for evaluating this condition in children and adolescents. In the pediatric population, there are difficulties for characterizing this condition and the various criteria used might lead to underdiagnosis. In recent years, the triglycerides/HDL (TG/HDL) ratio has been proposed as a new marker.Objec...

Serum IGF-I, IGFBP-3 and Als Concentrations and Physical Performance in Young Swimers During a Training Season

Filho Hugo Tourinho , Pires Marcela , Puggia E F , Papoti M , Barbieri R , Martinelli Jr Carlos

Background: Exercise programs are related to the anabolic function of GH/IGF-I axis.Objective and hypotheses: To analyse IGF-I, IGFBP-3 and ALS serum concentrations in adolescent swimmers at different stages of training season, and compare them with physical performance and body composition.Method: Nine male athletes, aged 16–19 years, who trained regularly throughout the season, were studied. IGF-I, IGFBP-3 and ALS were recor...

Acute Effects of a Training Session on IGF1 and IGFBP3 Concentrations in Brazilian Jiu-Jitsu Fighters

Filho Hugo Tourinho , Puggina Enrico , Moraes Camila , Oliveira L , Martinelli Jr Carlos

Introduction: The relationship between sports intensity and growth has become a concern in teenagers. Changes in the GH/IGF1 axis have been studied as biomarkers for training intensity in adolescents; however, reports on the effects of physical effort on GH and IGF1 levels are discordant and studies on GH and IGF1 responses in combat sports are scarce.Aim: To investigate the effects of a Jiu-Jitsu training session on serum IGF1 and IGFBP3 concentrations....

Disease Burden and Systemic Manifestations of HPP in Children Enrolled in the Global HPP Registry

Hogler Wolfgang , Langman Craig , Gomes Da Silva Hugo , Fang Shona , Linglart Agnes , Ozono Keiichi , Petryk Anna , Rockman-Greenberg Cheryl , Seefried Lothar , Kishnani Priya

Hypophosphatasia (HPP) is a rare, inherited, systemic disease caused by mutation(s) of the ALPL gene encoding tissue-nonspecific alkaline phosphatase (ALP), resulting in deficient ALP activity. Asfotase alfa is an enzyme replacement therapy approved for treatment of patients with pediatric-onset HPP. The global HPP Registry is an observational, prospective, multinational study (NCT02306720; EUPAS13514) established to collect real world clinical data from patients of a...

Background: In a recent report we have identified multinodular goiter (MNG) as a condition with an increased risk for thyroid malignancy in children and adolescents.Objective and hypotheses: To report the prevalence and characterization of a prospectively and uniformly followed cohort of pediatric patients with MNG and to retrospectively analyze differences between benign and malignant MNG before surgery in order to identify malignancy predictors.<p ...

Introduction: IPEX syndrome is a syndrome characterized by the following triad: immune dysregulation, polyendocrinopathy and X-linked enteropathy. It is produced by a variant in the FOXP3 gene. It is a rare disease with poor prognosis.Clinical case: We are reporting the case of a boy, 2nd child of non-consanguineous parents, normal pregnancy. Born at 39 weeks of gestational age, birth weight 2985 grams and length 49 cent...
