Background: Insulin deficiency inhibits protein synthesis and stimulates protein degradation, and then amino acids metabolism could be altered in diabetes mellitus.Objective: The aim of this study is to analyze amino acid plasma profile in a group of children with type 1 diabetes, and to evaluate its potential application as markers of metabolic control of the disease.Subjects/Methods: A clinical assessment and metabolic study (ami...

Background: RARβ cooperates with Nur77 to in-vitro regulate HSD3B2 transcription. NUR77 expression parallels HSD3B2 expression with a much lower level in androgen-producing adrenocortical tissues (childhood virilizing adrenocortical tumours (VAT), fetal zone (FeZ) and zona reticularis, ZR). RARβ is down-regulated in starved, hyperandrogenic H295R cells. However, the mechanisms regulating this expression pattern and the relevance of RARβ to huma...

Background: Glucocorticoids play an important role in the developing fetus; the most important of which is lung maturation by increasing surfactant production and release. Glucocorticoid receptor (GR) functioning changes throughout the fetal period, especially during the transition to extrauterine life. Given the importance of glucocorticoids in lung development and functioning, studying glucocorticoid sensitivity (GS) in this population would be helpful, especially in the pre...

Background: 2015 ATA Guidelines for management of medullary thyroid cancer (MTC) include C634 RET codon mutation in ‘High risk’ group, recomendating prophylactic thryroidectomy before 5 years old based on serum basal calcitonin levels (SBCt).Objective and hypotheses: We present 14 pediatric patients with C634 RET codon mutation, who underwent prophylactic thyroidectomy in our center, their clinical and analytical features and anatomopathologica...

Introduction: The epidemiology of childhood type 1 diabetes (DM1) allows to understand the genetics and enviromental factors involve in one of the most prevalent chronic disease in children. The unification of methodological recommendations has allowed to detect new research lines.Method: We present an observational study of population under 13 years old and DM1 in Extremadura (1996–2011). The aim was to examine secular trends in the incidence of DM...

Background: Ovarian function in young females with cancer can be damaged due to chemo-radiotherapy. One option to preserve fertility in these patients is the cryopreservation of ovarian tissue, but this is still experimental.Objective and hypotheses: Evaluate our experience with cryopreservation (indications, complications, and reimplantation). Through surveys, understand patient perspectives.Method: A total of 63 women were diagno...

Background: Skeletal muscle is the largest tissue involved in the insulin-stimulated disposal of glucose, with its size being controlled by hormonal status, among other factors. Leptin plays a primary role in the regulation of glucose homeostasis with a substantial degree of insulin and leptin cross-talk in muscle. However, the relationship between the leptin’s central effects on insulin sensitivity in muscle and associated structural changes remain unclear.<p class="...

Background: The integration of technology in health care has led to improved medical care and better compliance, especially in chronic diseases such as diabetes. Despite these advances, compliance has always been an issue in caring for adolescents with diabetes. Text messaging has become a popular way to communicate with peers especially for teens. Multiple studies support the theory that texting is an easy and affordable resource that health care providers can utilise to educ...

After the evident socio-health transformation when facing intersexualities / entities with different sexual development (DSD), we wonder if clinical-care assistance has improved. Material and method Descriptive multicenter study by means of a retrospective review (2006-2019) of patients with a diagnosis of DSD in pediatric age. Interdisciplinary assessment through satisfaction surveys to families / patients.Results: 67 patients were included. 27% were op...

Pregnancy associated plasma protein (PAPP)-A2 is an insulin-like growth factor (IGF) binding protein (BP) protease that regulates IGF-1 availability affecting postnatal growth. Mutations in human PAPP-A2 cause short stature and changes in bone size and mineral density. The present study aimed to characterize the effects of constitutive Pappa2 gene deletion on hypothalamic regulation of energy homeostasis in adult male and female mice. In addition to being sho...
