Treatment Patterns in Acromegaly: Analysis of Real-World US Insurance Claims from the MarketScan® Database

Brue Thierry , Fleseriu Maria , Barkan Ariel , Duquesne Edouard , Houchard Aude , del Pilar Schneider Maria , Ribeiro-Oliveira Antonio , Melmed Shlomo K.

Background: Medical treatment for acromegaly (characterized by excess growth hormone [GH] production) includes somatostatin receptor ligands (SRLs), dopamine agonists (DAs), and GH receptor antagonists (GHRAs). However, recent real-world United States (US) treatment evaluations are few. We present treatment patterns for patients receiving medications for acromegaly (1/1/2010–31/7/2022).Methods: De-identified data were extracted from MarketScan&...

Mitochondrial uncoupling proteins (UCPs) regulate mitochondrial function in mouse Leydig Cells: a possible role on steroidogenesis?

Guerra-Carvalho Barbara , Matos Beatriz C. , Carrageta David F. , Bernardino Raquel L. , Oliveira Pedro F. , Alves Marco G.

Introduction: Mitochondrial uncoupling proteins (UCPs) are transmembrane channels present in the inner mitochondrial membrane whose function is the transport of protons and small substrates between the intermembrane space and the mitochondrial matrix. UCPs are key regulators of cellular metabolism, including mitochondrial function, oxidative phosphorylation, and reactive oxygen species (ROS) production. UCPs’ dysfunction has been associated with the onset of metabolic dis...

Insulin-like growth factors: possible players regarding male fertility

Agualusa Nair , Carrageta David F. , Pereira Sara C. , Barros Alberto , Crisostomo Luis , Alves Marco G. , Oliveira Pedro F.

Infertility affects about 15% of couples, and, among these, 50% are related to the male factor. Male infertility can be caused by intrinsic factors, and these may either directly or indirectly affect gamete and testicular development as a consequence of endocrinopathies. In that sense, research regarding the involvement of endocrine hormones, particularly of nutritional status-linked hormones, in the male reproductive system has increased over the years. In fact, the rise on t...

BRCA1/2 Negative Bilateral Metastasized Breast Cancer Following Ovarian Stimulation: A Case Report

Oliveira Torres Joao , Leao Mendes Jose , Jorge Escaleira Rui , Alves Gaspar Mariana , Malheiro Rui , Martins Diana , Silva-Nunes Jose

Introduction: Breast cancer is the second most common neoplasm in women. Hormonal replacement therapy and combined hormonal contraception are established extrinsic hormonal risk factors for breast cancer. Therefore, the increase in the prevalence of infertility and the use of assisted conception techniques have raised questions regarding the potential risk of hormone-dependent neoplasms. We report the case of a woman diagnosed with bilateral metastasized breast cancer soon aft...

Pheochromocytoma, unmasking the chameleon

Cunha Clara , Ferrinho Catia , Santos Francisco Sousa , Silva Eugenia , Fernandes Luis Viana , Saraiva Catarina , Oliveira Manuela , Duarte Joao Sequeira

Background: Pheochromocytoma is a rare catecholamine secreting tumor originating usually from adrenal medulla and representing approximately 5% of adrenal incidentalomas. Currently 10% of all pheochromocytomas are discovered incidentally during imaging studies for unrelated disorders.Case presentation: A thirty five year old woman with no relevant medical history presented at the emergency department with symptoms of left flank pain and vomiting. Abdomin...

CGI-58 gene expression is decreased in the subcutaneous adipose tissue of patients with obesity

Sortica Denise , Rheinheimer Jakeline , de Souza Bianca , de Oliveira Mayara , Moehlecke Milene , Leitao Cristiane , Carla Bauer Andrea , Crispim Daisy

Background and aims: In adipose tissue, excess of energy is stored inside cytosolic lipid droplets as triglycerides. During fasting or exercise, the stored fat is mobilized for utilization as free fatty acids and glycerol via lipolysis. The complete lipolysis of triglycerides is mediated by the orchestrated activation of adipose triglyceride lipase (ATGL) and hormone-sensitive lipase, which have been associated with obesity. There is compelling evidence that the protein compar...

Malignant lentigo melanoma in patient with agressive thyroid folicular carcinoma

Leite Luciana Pedral S D , Pithon Ricardo B , Oliveira Nathalie S , Roriz Renata B , Silva Bruna L

Lentigo malign melanoma corresponds to the main histological type of melanomas ‘in situ’, particularly affecting Caucasian elderly exposed chronically to the ultraviolet rays. The therapeutic course should be surgical, with careful resection of the tumor, allowing free and wide margins. Follicular thyroid carcinoma corresponds to the second most common histological type characterized as a well differentiated neoplasm. It presents markedly vascular dissemination, bein...

Adrenal incidentalomas – from diagnosis to follow-up

Cunha Clara , Capitao Ricardo , Bello Carlos Tavares , Santos Francisco Sousa , Roque Catarina , Saraiva Catarina , Duarte Joao Sequeira , Oliveira Manuela

Introduction: Adrenal incidentalomas (AIs) are defined as adrenal masses measuring 10 mm or more in diameter, incidentally discovered on imaging exams performed for a non-adrenal disorder. The aim of this study is to provide a clinical and imagiological characterization of patients diagnosed with AIs followed in our institution.Methods: We conducted an observational and retrospective study that included patients with AIs evaluated at our institution betw...

Relative fat mass correlates better than BMI with total body fat – experience of an obesity clinic

Ferrinho Catia , Bello Carlos , Santos Francisco Sousa , Capitao Ricardo , Ferreira Rute , Limbert Clotilde , Duarte Joao Sequeira , Oliveira Manuela

Introduction: A simple linear anthropometric linear equation for total body fat quantification in adults was recently selected as the best of 365 anthropometric indexes in the American population. The authors intend to evaluate the correlation between the relative fat mass (RFM) equation and body fat determination by electric bioimpedance (EB) and compare it with BMI.Material/methods: Retrospective, cross-sectional, observational study that selected all ...

Ferrinho Catia , Matos Ana Catarina , Cordeiro Maria Carlos , Bastos Filipa , Ferreira Rute , Duarte Joao Sequeira , Oliveira Manuela , Portugal Jorge

Introduction: Gestational Diabetes Mellitus (GDM) is one of the pregnancy diseases with the highest rate of complications, influenced by several factors. Its prevalence has increased, with a prevalence of 7.2% in Portugal.Objective: Characterize pregnant women with GDM and evaluate the perinatal outcomes according to the country of origin and previous GDM.Material and methods: Cross-sectional and retrospective study. We collected c...
