IntroductionThe most cost-effective, minimally invasive and accurate tool to discriminate benign from malignant thyroid nodules is a fine-needle aspiration biopsy (FNAB). However, 2%–24% of FNABs provide non-diagnostic results, which are a clinical challenge, particularly when this result is recurrent.AimTo determine the predictive factors for recurrent non-diagnostic FNAB in thyroid nodules.<p class...

IntroductionRecent published studies suggest that the anatomical location of the thyroid nodule may be associated with different risks of malignancy. However, the results are still sparce and little consensual.AimTo evaluate the frequency of nodules on different locations of the thyroid gland and to determine whether their location correlates with different malignancy risks.Methods<...

BackgroundGraves’ Disease (GD) is characterized by production of stimulating autoantibodies to thyrotropin receptor resulting in hyperthyroidism. Hyperthyroidism is associated with insulin resistance, hyperglycemia and ketosis. Our aim was to evaluate if single nucleotide polymorphism (SNP) in pro-inflammatory cytokines contributes to dysglycemia in GD.MethodsWe evaluated 98 patients with Graves’ di...

IntroductionHypoparathyroidism (hypoPT) is one of the most complications after thyroid surgery, usually as transient hypocalcemia. Permanent hypoPT due to permanent parathyoid lesion, despite being less frequent, is associated to long term consequences for both objective and subjective well-being and should be prevented. Identifying predictive factors associated with post- thyroidectomy hypoPT is thereby crucial.Aim<p class="ab...

IntroductionCOVID-19 is an emerging disease caused by the new coronavirus (SARS-CoV-2) that has overburdened healthcare worldwide. In Portugal, schedule appointments were cancelled, postponed or changed to tele-consultation. The objective of the study is to assess the impact of the pandemic on the use of Emergency Department (ED) by diabetic patients.Material and methodsRetrospective monocentric study of the ...

Introduction: Mitochondrial uncoupling proteins (UCPs) are channel proteins present in the mitochondrial inner membrane which are responsible for the transport of protons between the mitochondrial intermembrane space and the matrix. Currently, six UCP homologues had been identified (UCP1-6). UCPs are major regulators of reactive oxygen species (ROS) production, general cellular redox state and metabolism. UCPs also exhibit specific functions, such as UCP1 and thermogenesis or ...

Metabolic and endocrine dysregulation induced by high-fat diet (HFD) can lead to decreased male fertility potential and have a negative impact on the offspring’s metabolic health. Small non-coding RNAs (sncRNAs) were proposed as being potential mediators of metabolic queues across transgenerational inheritance. During development and epidydimal transit, spermatozoa become enriched with tRNA-derived stress-induced RNAs (tiRNAs). This sncRNAs class appears to be particularl...

Background: In 15% of prolactinomas there is dopamine agonist(DA) resistance. The clinical characteristics, the best diagnostic and therapeutic management of these cases have not been established so far.Aim: To characterize patients taking a high dose cabergoline(≥ 3mg/week) and then describe clinical, biochemical and imaging features of cabergoline-resistant cases.Methods: Retrospective study with 5 centers representing the ...

Introduction: Atrazine is one of the most widely used pesticides worldwide and a common contaminant in human drinking water. Atrazine is also a potent endocrine disruptor capable of causing a variety of negative health outcomes, including decreased testosterone production and infertility. Although harmful effects of atrazine on male reproductive health have been reported, little is known about its molecular mechanisms. Within the seminiferous tubules, Sertoli cells are respons...

This paper aims to describe the followed population in the consultation, through a retrospective study in a hospital unit. This retrospective study was carried out during February 2020 to February 2022, and analyses the clinical processes of the patients that were followed in this consultation, and later analysing the data using Microsoft Excel® Over these two years, 395 patients were observed. These patients age average 61 years old, ranging from 17 to 93 years of age. M...
