Circulating microRNAs expression profile in individuals with obesity compared to healthy controls

Assmann Tais Silveira , Milagro Fermin I , Cuervo Marta , Riezu-Boj Jose I , Martinez J Alfredo

Context: Obesity is a global epidemic and an independent risk factor for several metabolic disorders. Emerging evidence suggests a role for epigenetic factors, such as microRNAs (miRNAs), in the development of obesity. MiRNAs are small non-coding RNAs that regulate gene expression. Moreover, circulating miRNAs are potential noninvasive biomarkers because they are stable in body fluids and can be detected using validated techniques, such as quantitative PCR. However, the identi...

Primary thyroid angiosarcoma – a case report

Bala Nadia Mourinho , Aragues Jose Maria , Guerra Silvia , Roque Rita , Madureira Rosa , Valadas Cristina

Introduction: Primary thyroid angiosarcoma (TAS) is a rare malignancy that arises from endothelial cells, and nearly all reported cases originate from the Alpine region of central Europe. Most of the patients are female, elderly, with a history of goiter. Generally, TAS arises as a painless infiltrating mass and patients present with compression symptoms due to the brisk tumor growth. Other TAS clinical presentations are varied and highly non-specific. Metastasis occur early i...

A diagnosis challenge: endogenous hyperinsulinism and negative localisation tests: case report

Fernandez-Ladreda Mariana Tome , Schuldt Maria Belen Ojeda , Cuenca Jose Carlos Padillo

Introduction: Persistent hyperinsulinemic hypoglycemia may be caused either by a solitary tumor of the pancreas secreting excessive amount of insulin, known as insulinoma or, rarely, by nesidioblastosis. Nesidioblastosis is a rare cause of persistent hyperinsulinemic hypoglycemia in adults.Methods: We describe the case of a 25-year-old male patient who was referred to our clinic for repeted hypoglycemia episodes.Results: Our patien...

Resistance training reduces skeletal muscle inflammation even after 4-week detraining in obese rats

Seraphim Patricia , Freitas Marcelo , Teixeira Marcos , Teixeira Giovana , Nunes Maria Tereza , Filho Jose Carlos Camargo

The ingestion of high-fat diet has been considered a crucial factor in the genesis of subclinical systemic inflammation and insulin resistance. The resistance training (RTr) can be an effective tool for the prevention and treatment of immune-metabolic disorders through physiological and morphological adaptations. The purpose of the present study was to analyze the effects of RTr and cessation of training on muscle inflammation and expression of genes related to glucose metabol...

Medullary thyroid carcinoma and pheochromocytoma in multiple endocrine neoplasia type 2A – a reversed order diagnosis

Gomes Ana Coelho , Silvestre Catarina , Marcalo Jose , Carvalho Maria Raquel , Bugalho Maria Joao

Introduction: RET germline mutation in codon 634 of exon 11 is one of the most frequent mutations of classical multiple endocrine neoplasia type 2A (MEN2A). Virtually all patients with classical MEN2A develop medullary thyroid carcinoma (MTC), which is often the first manifestation of the disease and usually occurs early in life. Pheochromocytomas (PHEOs) tend to be diagnosed several years later or simultaneously with the MTC.Case report: The pa...

The importance of ultrasound in the preoperative evaluation of patients with primary hyperthyroidism: a case report

Marcalo Jose , Araujo Alexandra , Wessling Ana , Carvalho Maria Raquel , Bugalho Maria Joao

Introduction: Primary hyperparathyroidism is the most common cause of hypercalcemia in the outpatient setting, and a single parathyroid adenoma is usually the culprit. Clinical presentation is commonly dictated by hypercalcemia. Symptoms can range from mild non-specific malaise and gastrointestinal disturbances, through bone disease, kidney stones, cardiovascular and neuromuscular dysfunction to, ultimately, coma and death. However, the vast majority of patien...

Parathyroid nodular hyperplasia: when imaging exams fail

Osorio Ana Sofia , Rocha Jose , Faria Carolina , Barbosa David , Nobre Ema , Bugalho Maria Joao

Introduction: Parathyroid hyperplasia is the second cause of primary hyperparathyroidism (PH), representing 15–20% of all cases. The scintigraphy with Tc-99m-Sestamibi is a preoperative exam used to identify parathyroid adenomas or hyperplasia. It has a sensibility of 50–90%, which increases with larger parathyroid size. The neck ultrasonography (US) has also an important role detecting parathyroid enlarged glands with 70% sensibility. We report a case of parathyroid...

Can hypoglycemic episodes in type 1 diabetics trigger cardiac arrhythmias?

Lainetti Kelly Regina , Pimenta Joao , Vendramini Marcio Faleiros , Cassiolato Jose Luiz B.

Type 1 diabetes mellitus (DM1) accounts for 5 to 10% of DM cases, and can occur both in childhood and adults. Studies show an association between severe hypoglycemia and increased vulnerability to cardiac arrhythmias due to conduction disorders, interval ST-segment changes, and even sudden death. The aim of this study is to evaluate the occurrence of cardiac arrhythmias during episodes of hypoglycemia. A prospective study with DM1 patients under insulin therapy for at least 5 ...

Unacylated ghrelin does not seem to influence glucose homeostasis in obese women

Silva-Nunes Jose , Brito Miguel , Silva Carina , Oliveira Ana , Veiga Luisa

Background and Aim: Unacylated ghrelin (UAG) is the major form of circulating ghrelin. Initially considered as a non-functional peptide, soon after UAG has been associated to a negative action on energy balance, suppression of hepatic glucose production and decrease in circulating levels of insulin. The aim of this study was to analyze the association between the serum levels of UAG and glucose metabolism parameters in obese women, independently from the eventual interference ...
