Predictive factors for postoperative hypoparathyroidism after total thyroidectomy

Santos Tiago , André Carvalho , Cláudia Freitas , Raquel da Inez Correia , Costa Moreira da , Cardoso Maria Helena

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...

Clinical and histopathological factors associated with the prognosis of medullary thyroid cancer in a tertiary center

Martins Ferreira Mafalda , Carvalho Tania , Madeira Joana , Lopes Sofia , Melo Miguel , Ribeiro Cristina , Saraiva Joana , Oliveira Patricia , Paiva Isabel

Introduction: Medullary thyroid cancer (MTC) is a rare tumour. Mostly sporadic, 25% are associated with multiple endocrine neoplasia (MEN2A/B) or isolated familial MTC. Surgery is the only curative option: its response is defined as complete (no evidence of biochemical or structural disease), incomplete (only structural response) and persistence of structural disease. We aimed to analyse the clinical and pathological factors associated with the prognosis of MTC.<p class="a...

Severe Hypercalcemia After Parathyroidectomy: When the Unexpected Happens

Carvalho Tania , Rodrigues Gustavo , Filipa Araujo Barbara , Saraiva Joana , Ventura Mara , Gouveia Sofia , Rodrigues Dircea , Paiva Isabel

Introduction: Severe hypercalcemia is defined as a total serum calcium level >14 mg/dl or ionized calcium >10 mg/dl . The most common causes are primary hyperparathyroidism (PHPT) and neoplasms (90% of cases). Vitamin D intoxication is an extremely rare cause. Case Report: A 56-year-old man presented to the emergency department with vomiting, generalized weakness and complaints of imbalance over one week. Upon physical examination, he displayed c...

Medullary thyroid carcinoma – a 22-year case series from a tertiary hospital center

Carvalho Tania , Martins Ferreira Mafalda , Madeira Joana , Lopes Sofia , Saraiva Joana , Oliveira Patricia , Melo Miguel , Ribeiro Cristina , Paiva Isabel

Introduction: Medullary thyroid carcinoma (MTC) arises from thyroid parafollicular C cells and accounts for <5% of thyroid cancers. Nearly 25% occur in the context of multiple endocrine neoplasia type 2 syndrome (MEN2) or familial isolated MTC.Objectives: Evaluation of clinical characteristics and evolution of patients with MTC.Methods: Retrospective analysis of clinical records of patients with MTC diagnosed from 2001 to 2023....

Mitochondrial uncoupling proteins (UCPs) regulate the mitochondrial activity of human sertoli cells

Carrageta David F. , Freire-Brito Lais , Monteiro Bruno S. , Guerra-Carvalho Barbara , Bernardino Raquel L. , Oliveira Pedro F. , Monteiro Mariana P. , Alves Marco G.

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 ...

High-fat diet promotes 3’mt-tiRNA-Met epididymosome enrichment which correlates to lower spermatozoa mitochondrial translation

Pereira Sara C. , Freire-Brito Lais , Guerra-Carvalho Barbara , Carrageta David F. , Bernardino Raquel , Crisostomo Luis , Terzo Simona , Monteiro Mariana P. , Oliveira Pedro F. , Allegra Mario , Alves Marco

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...

Prolactinomas under high doses cabergoline in portuguese patients: The Resistant Prolactinoma Study

Manique Ines , Benido Silva Vania , Carvalho Davide , Marques Olinda , Nobre Ema , Joao Bugalho Maria , Palha Ana , Ribeiro Isabel , Pereira Josue , Almeida Rui , Sagarribay Amets , Cerqueira Luis , Amaral Claudia

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 ...

In vitro exposure to the endocrine disruptor atrazine induces a pro-oxidant state and modulates mouse Sertoli cells metabolic support of spermatogenesis

Gomes-Andrade Daniela , Guerra-Carvalho Barbara , Carrageta David F. , Bernardino Raquel L. , Oliveira Pedro F. , de Lourdes Pereira Maria , Alves Marco G.

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...

Silva Maria Helena F. , Serejo Portugal Rita , Matos Goncalves Andre , Nagirnyak Volodymyr , Gabriel Oliveira Baltazar , Marques Carlos , Cabeleira Joana , Rita Sanches Ana , Cunha Martins Sonia , Sousa Carvalho Margarida

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...
