Because of its critical need during pregnancy, several countries implemented programs of iodine supplementation in preconception and pregnancy. In 2013, the prevalence of iodine deficiency in Portugal has led health authorities to issue a recommendation for iodine supplementation. This study aims to evaluate the impact of iodine supplementation on maternal and fetal iodine status and thyroid function, obstetric outcomes, quality of breast milk and child psychomotor development. It also intends to evaluate whether the time of iodine supplementation initiation influences all the above-mentioned parameters. The novelty and relevance of this study reside on the number of women/child and on the extent of health parameters that will be evaluated. The information collected will contribute to the detailed characterization of thyroid hormone homeostasis throughout pregnancy and its relationship with iodine supplementation (including time of initiation). The data will provide evidence on whether this iodine supplementation strategy impacted on iodine sufficiency of the mother and the newborns, or if it needs re-evaluation.
Obesity is a growing public health concern in most western countries. More and more patients with high body mass index (BMI) are undergoing surgical procedures of all kinds and, in this context, obese patients are undergoing thyroid surgery more than ever before. This study showed that obesity, in the field of thyroid surgery, is not associated with any increase of postoperative complications. Thus, it is possible to conclude that thyroidectomy can be performed safely in obese patients.
A multicenter open-label phase 1/1b study to evaluate the safety and preliminary efficacy of SO-C101 as monotherapy and in combination with pembrolizumab in patients with selected advanced/metastatic solid tumors
Intraoperative Neuromonitoring (IONM) was started to be used by surgeons to help prevent laryngeal nerve (RLN) damage during thyroid and parathyroid operations. IONM can be used to localize and identify RLN intraoperatively, to evaluate vocal function after thyroid resection, and to explain the mechanism of RLN injury. However, an important problem in the routine use of IONM is the effect of neuromuscular blocking agents (NMBAs). The use of NMBAs in general anesthesia is essential to provide clinically acceptable tracheal intubation conditions and to prevent laryngeal trauma. However, NMBAs may be the potential cause of a false-negative response during the IONM. Randolph et al. proposed short-acting 1-2 mg/kg succinylcholine for enough relaxation and the ease of electromyographic (EMG) endotracheal tube intubation during the IONM. However, succinylcholine, a depolarizing NMBA, is associated with various adverse effects such as cardiac arrhythmia, hyperkalemia, and malignant hyperthermia. Nondepolarizing NMBAs are widely used by most anesthesiologists due to their safe effects, but to the best our knowledge, there is no very short-acting nondepolarizing NMBA. This deficiency creates a problem because the dose and the time point of nerve stimulation are critical for a successful IONM. However, some studies have reported the feasibility of IONM following the administration of nondepolarizing NMBAs during a thyroid operation. Rocuronium is a short-acting and nondepolarizing NMBA type which is widely used for induction in general anesthesia. Although 0.6 mg/kg rocuronium is recommended for standard intubation dose, the ease of intubation can also be provided with 0.3 mg/kg rocuronium or 1.5 mg/kg succinylcholine. Therefore, the present study was designed to compare the effects of IONM with low and standard rocuronium doses in the induction of general anesthesia.
Thyroid disorders are most commonly concomitant with prematurity and still remains a controversial topic. The incidence of a temporary form of hypothyroidism among preterm neonates is higher than in the general population. Transient prematurity hypothyroxinemia is defined as a temporary reduction in FT4 values without increase in TSH values. Currently, there is no consensus about normal thyrotropine (TSH) and free thyroxine (FT4) values in preterm infants. The aim of this study is to determine the volume of the thyroid gland in preterm infants born between 24 and 32 weeks of gestation inborn or admitted to the unit within 14 days from birth and compare it with the results of TSH and FT4 blood concentration. Besides, the objective of the study is to determine values of thyroid hormones in premature infants born before 33 wk gestation to help neonatologist to interpreter the thyroid hormone results
The purpose of this study is to determine Safety and Efficacy of Radioactive Iodine (RAI) Treatment of Metastatic and Advanced Differentiated Thyroid Cancers by Pretreatment With Apatinib for the Neoadjuvant Regimen
This study is designed as a prospective non-randomized longitudinal single-center cohort study. It will enroll around 120 patients undergoing total thyroidectomy with data being collected from September 2019 up to December 2019. The hypothesis is that a significant association and cut-off point in PTH levels may be established with regard to postoperativne hypocalcaemia. Primary outcome measures are presence of hypocalcemia on the first and fifth postoperative day. Secondary outcome measures are the need for calcium supplement therapy during the first five postoperative days and amount of medication given. Associations between variables will be assessed using Spearman's rho rank correlation coefficient, the Kruskal-Wallis test for independent samples and a logistic regression model to test statistically significant correlations between PTH and serum calcium values as a primary end point.
It is hypothesized that instillation of Liothyronine Sodium (T3) into the airspace will be safe, well tolerated, and will increase alveolar fluid clearance and decrease inflammation in patients with ARDS, reflected in improved oxygenation index (OI) and oxygenation saturation index (OSI).
The question proposed by this study, is one of patient outcomes. Does intraoperative injection of Exparel decrease postoperative use of opioid pain medications in patients undergoing thyroid and parathyroid surgery? The trial seeks to assess the effect that Exparel has on postoperative pain control.
The incidence of autoimmune diseases (celiac disease, type 1 diabetes, thyroid disease) have increased over the past 30 years. Although most autoimmune diseases have a strong link to different risk genes, the rapid increase is thought to be due to changes in environmental factors. There is currently no cure for autoimmune diseases, but the treatment is lifelong and either involves suppressing the inflammation and / or substituting the organs that are affected to maintain vital functions. Being able to predict who is affected and identifying factors that trigger autoimmunity is necessary for developing new treatment methods that prevent the occurrence of autoimmune diseases. The bacterial flora's composition in the gut can affect both the intestinal barrier properties and the immune system's response to various dietary components. An adverse composition of the intestinal flora can activate parts of the immune system that are involved in chronic inflammation in celiac disease and inflammatory bowel disease. Probiotics are defined as living microorganisms which, when ingested in sufficient amounts, produce a health effect (FAO / WHO). The aim of the study is to investigate whether a daily oral intake of a mixture of L.paracasei and L.plantarum can affect the autoimmune process in children who are screened positive for any of the autoantibodies associated with development of celiac disease, type 1 diabetes and / or thyroid disease. Our hypothesis is that lactobacilli can directly regulate the autoimmune process in the small intestinal mucosa by stimulating regulatory T-cells, but also by affecting the permeability of the small intestinal mucosa by of antigen that stimulates specific T-cells.
