Abstract In recent years, long non-coding RNAs have emerged as a novel class of regulators cancer biological processes. While they are dysregulated in many types, little is known about their expression and functional profiles. This study has been focused on the determination role specific lncRNA papillary thyroid cancer. Quantitative reverse transcription PCR was performed to detect levels 84 lncRNAs 61 carcinoma tissues adjacent non-tumor tissues. The highest fold-change obtained for lung...

We investigated the use patterns and indications of intraoperative neural monitoring (IONM) among endocrine surgeons in Spain. sent an anonymous web-based survey to surgeons' members Spanish Association Surgery by email. analysed 79/ 269 surveys. Respondents had a median age 52 years 13 surgical experience. Only 32% respondents performed routinely preoperative laryngoscopy all thyroidectomies 19% parathyroidectomies. Seventy-five percent used intermittent-IONM, 9.7% continuous-IONM. All...

Background: Obesity is the most frecuent metabolic disease in World, and associated with several comorbidities. Bariatric procedures arise as a promising treatment when classical approach ineffective. Half of operated patients are reproductive-aged women there evidence that obesity related to worse maternal fetal outcomes. Because nutritional status affected by bariatric surgery vital component during pregnancy, aim our study asses impact on pregnancy these pacients. Material methods: We...

Objective: To evaluate whether the combined use of fetal heart rate (FHR) and nuchal translucency measurements would be useful in prediction chromosomal abnormalities at 10–13 weeks' gestation. Methods: In a prospective study, 1053 (553 reported previously) consecutive singleton pregnancies between 10 13 gestation underwent chorionic villus sampling our institution. Fetal thickness were measured immediately before invasive procedure. Results: Thirty-five abnormal karyotypes diagnosed,...

Familial adenomatous polyposis (FAP) is an autosomal dominant cancer predisposition syndrome characterised by the progressive development of multiple colorectal polyps and increased incidence carcinoma. It often accompanied other benign or malignant extracolonic manifestations, including gastric duodenal tumours, osteomas, desmoid retinal pigmentation, thyroid adrenocortical tumoursWe report case a 42-year-old white female with FAP who was referred to our Endocrine Surgery Unit for surgery...

To explore the utility of intrapulmonary Doppler in predicting severe neonatal pulmonary hypertension fetuses with congenital diaphragmatic hernia (CDH) treated fetoscopic tracheal occlusion (FETO). A cohort 51 left-sided CDH liver herniation and an observed/expected lung to head ratio (LHR) below 45%, FETO between 26 33 weeks gestation. Intrapulmonary Pulsatility Index (PI) peak early diastolic reversed flow (PEDRF) were evaluated 1 day before FETO, their isolated combined value predict...

To describe presurgical cardiac function parameters in monochorionic twins with twin-twin transfusion syndrome (TTTS) relation to Quintero stages and assess their ability predict early intrauterine fetal demise (IUFD) after therapy. 102 pregnancies complicated TTTS treated fetoscopic laser coagulation were prospectively included. All classified by stages. Presurgical Doppler assessment was performed 24 hours before surgical treatment each fetus including ductus venosus (DV), myocardial...

To assess brain volume, cortical sulcation and metabolism using magnetic resonance (MRI) spectroscopy in term fetuses with major congenital heart defects (CHD) compared controls. A total of 58 CHD controls underwent a 3T MRI-MRS exam at 37 weeks. Anatomical acquisitions were obtained three planes spectroscopic evaluation was performed on the frontal lobe (FL) basal ganglia (BG). Volumetric parameters (brain, intracranial opercular volumes) fissure depths (sylvian, parietoccipital, cingulate...
