Preoperative vitamin b1 levels are associated with reaching normal body mass index 1 year after bariatric surgery

Silva Bruna , Pereira Catarina , Chaves Catarina , Basto Tatiana , Gil Catarina , Alvarez Cesar , Cunha Filipe

Introduction: Vitamin B1 (VB1) deficiency can occur in patients with obesity and after bariatric surgery (BS). Nevertheless, pre-operative measurements of VB1 are still controversial. The relationship between serum VB1 and weight loss after BS has not been reported previously.Objectives: To study the association between pre-operative VB1 levels and weight loss after BS.Methods: Retrospective study of patients submitted to bariatric...

Interrelationships between thyroid function, autoimmunity, low-grade inflammation, lipid profile and insulin resistance in graves’ disease

Neves Celestino , Sergio Neves Joao , Miguel Pereira Luis , Sokhatska Oksana , Queiros Joana , Luis Delgado Jose

Aim: The aim of this study was to evaluate the association between thyroid function in Graves’ disease (GD) with high-sensitivity C-reactive protein (hs-CRP), lipid profile, homocysteine, folate, vitamin B12 and insulin resistance.Methods: We performed a cross-sectional of 104 patients with recently diagnosed GD. All participants were in the first cycle of treatment with methimazole. We collected demographic information, body mass indexes (BMI), lab...

Glutaminase 2 expression is associated with adrenocortical carcinoma patients’ survival

B. Oliveira Sofia , Pinto Clara , M. Costa Madalena , Sousa Diana , S. Pereira Sofia , Pignatelli Duarte

Adrenocortical carcinomas (ACC) are rare and usually very aggressive tumors with heterogeneous outcomes. The individual variability in tumor progression and patients’ survival is linked to ACC biology and molecular heterogeneity, reinforcing the need to identify markers with prognosis value, to allow an accurate clinical strategy. Currently, in the absence of specific molecular markers, ACC prognosis is mainly predicted by the European Network for the Study of Adrenal Tum...

IGF2 and Ki-67 as immunohistochemistry markers for adrenocortical tumors differential diagnosis: a systematic-review and meta-analysis

B. Oliveira Sofia , Machado Mariana , Sousa Diana , S. Pereira Sofia , Pignatelli Duarte

Most of adrenocortical tumors (ACT) are benign and non-functioning tumors, in contrast to adrenocortical carcinomas (ACC), which are rare and usually very aggressive tumors with a poor prognosis. The pathological discrimination between adrenocortical adenomas (ACA) and ACC is mainly based on unspecific and subjective histological features, resulting in inaccurate diagnosis in several cases. Numerous studies have previously described the potential value of immunohistochemistry ...

Cyclic cushing’s syndrome: understanding the patterns of a complex endocrine disorder

Tavares da Silva Beatriz , Martins Fernandes Andreia , Almeida Raquel , Teresa Pereira Maria , Amaral Claudia

Introduction: Cyclic Cushing’s Syndrome is an uncommon disorder characterized by recurrent episodes of elevated cortisol levels, alternating with periods of normal cortisol secretion. These cycles of hypercortisolism can occur at regular or irregular intervals, ranging from days to years between episodes.Case presentation: A 57-year-old woman evaluated at the Endocrinology Outpatient Clinic because of symptoms of hypercortisolism with 18 months of e...

Ocular findings in adult subjects with congenital, lifetime, isolated, untreated growth hormone deficiency

Faro Augusto C N , Pereira-Gurgel Virginia M , Salvatori Roberto , Campos Viviane C , Melo Gustavo B , Oliveira Francielle T , Oliveira-Santos Alecia A , Oliveira Carla R P , Pereira Francisco A , Hellstrom Ann , Oliveira-Neto Luis A , Aguiar-Oliveira Manuel H

Ocular function is fundamental for environmental adaptation and survival capacity. Growth factors are thought to be necessary to reach a mature eyeball and consequent adequate vision. However, the consequences of the deficiency of circulating growth hormone (GH) and its effector insulin-like growth factor I (IGF-I) on the physical aspects of the human eye are still debated. A model of untreated isolated GH deficiency (IGHD) may clarify this issue. The aim of this study was to ...

Biochemical parameters in metabolic bone disease of obese patients

Binda Pereira Raquel , Santos Ana Carolina , Ferreira Joana , Mascarenhas Mario Rui , De Quinhones Levy Pilar , Barbosa Paula , Bicho Manuel

Introduction: Obesity is a pathological condition characterized by a low-grade systemic inflammatory state that predisposes to the onset of some diseases, such as hypertension, diabetes, and hyperlipidemia. Also, obesity can impact bone metabolism, but its effects are controversial.Aims: This observational study aimed to evaluate and correlate the bone mass with the lipidic profile, adipocytokines, glucose metabolism, hepatic function and purine metaboli...

Towards a pituitary apoplexy classification based on clinical presentation and patient journey

Guijt Mathijs , Zamanipoor Najafabadi Amir , Notting Irene , M Pereira Alberto , Verstegen Marco , Biermasz Nienke , van Furth Wouter , Claessen Kim

Purpose: The condition of pituitary apoplexy contains the clinical spectre from life-threatening emergency to a condition with chronic symptoms and self-limiting course, which partly determines diagnostic delay and management. Outcome evaluation of course and management of pituitary apoplexy is hampered by the diverse presentation of this condition and requires appraisal. This study aimed to describe the patient journey, clinical presentation and management of various types of...

Sperm medium supplementation with hyperoside as a potential strategy to counteract spermatozoa dysfunction associated with oxidative stress

Moreira Mafalda V. , Pereira Sara C. , Pinto Soraia , Barros Alberto , Silva Branca M. , Alves Marco G. , Oliveira Pedro F.

Infertility is a global health problem that affects about 15% of couples and approximately half of infertility cases are associated with male factors. Oxidative Stress (OS) is reported as one of the major causes of male infertility, mainly due to spermatozoa’s vulnerability to the attack of reactive oxygen species (ROS). Infertile couples often recur to assisted reproductive technology (ART) to achieve a successful pregnancy. However, ART protocols also increase the expos...
