Aim: Acromegaly is associated with premature dead and a number of risk factors for cardiovascular disease (CVD). We aimed to examine the concept of cumulative GH exposure with regard to the presence these risk factors and cancer in acromegalic patients.Methods: Retrospective observational study in all acromegalic patients from 2006 to 2017 with a minimum of 3 years of follow-up. We exclude patients not treated. GH exposure was calculated as median GH or ...

Bone material strength index is altered in patients with Cushing’s syndrome even after long-term remission

Schoeb Manuela , Sintenie Paula J.C. , Haalen Femke van , Nijhoff Michiel , de Vries Friso , Biermasz Nienke , Winter Elizabeth M. , Pereira Alberto M , Appelman-Dijkstra Natasha

BackgroundEndogenous Cushing’s syndrome (CS) is detrimental to bone. The skeletal complications are characterized by decreased bone formation and increased bone resorption, resulting in decreased bone mineral density (BMD) and an increased risk of fractures at time of diagnosis. After remission of the disease, BMD improves towards normal values but fracture rate remains elevated. Therefore, components of bone quality other than BMD, such as bone mat...

The absence of TSHR-GPER heteromers is a potential marker of thyroid cancer

Perri Carmela , D'Alessandro Sara , Paradiso Elia , Lazzaretti Clara , Mascolo Elisa , Baschieri Lara , Roy Neena , Sperduti Samantha , Simoni Manuela , Brigante Giulia , Casarini Livio

Thyroid cancer is the most common type of endocrine tumor and reaches the peak of incidence between the age of twenty and fifty years. It has 4-fold higher prevalence in females than males, suggesting that estrogens and their receptors could be involved in thyroid cancer pathogenesis. Previous studies demonstrated allosteric interference operated by G protein-coupled estrogen receptor (GPER) to molecules structurally similar to the thyroid-stimulating hormone (TSH) receptor (T...

Luteinizing hormone/choriogonadotropin receptor (LHCGR)/G protein-coupled estrogen receptor (GPER) heteromers impact on reproductive signals

Lazzaretti Clara , Paradiso Elia , Sperduti Samantha , Sayers Niamh , Pelagatti Ginevra , D'Alessandro Sara , Perri Carmela , Baschieri Lara , Simoni Manuela , Hanyaloglu Aylin Carla , Casarini Livio

Background: Follicle-stimulating hormone receptor (FSHR) and G protein-coupled estrogen receptor (GPER) are expressed on the surface of granulosa cells, where they form heteromeric complexes, shifting FSH-induced signals to survival pathways and determining the follicular fate.Objectives: We evaluated whether GPER can interact with the luteinizing hormone (LH)/choriogonadotropin (hCG) receptor (LHCGR) and modulate the LH/hCG/dependent signalling pathways...

Follicle stimulating hormone in male idiopathic infertility: How to predict its efficacy?

Romeo Marilina , Spaggiari Giorgia , Valentina Leonardo Dalla , Nuzzo Federico , Roli Laura , Santis Maria Cristina De , Trenti Tommaso , Granata Antonio R. M. , Simoni Manuela , Santi Daniele

Background: Testis stimulation with follicle stimulating hormone (FSH) is one of the empirical treatments proposed for male idiopathic infertility, although early reliable markers to predict its efficacy are still lacking.Objective: To identify the improvement of semen parameters required to predict a priori FSH efficacy in terms of pregnancy achievement.Methods: A real-world study was conducted, enrolling idiopathic infer...

Testosterone serum levels in idiopathic male infertility: An epidemiological insight with pathophysiological and clinical consequences

Costantino Francesco , Spaggiari Giorgia , Valentina Leonardo Dalla , Romeo Marilina , Roli Laura , De Santis Maria Cristina , Trenti Tommaso , Granata Antonio , Simoni Manuela , Santi Daniele

Background: Despite male idiopathic infertility is characterized by semen analysis alteration with gonadotropins within reference ranges, it is still considered a functional hypogonadotropic hypogonadism (FHH). This simple definition is fundamental to guide the empirical therapeutic approach of these men. However, the number of studies describing total testosterone serum levels (TT) in male idiopathic infertility is still limited.Objective: To evaluate T...

Irisin levels are correlated with age and behavioural performance in Post-surgical HypoPT condition

Saponaro Federica , Chiellini Grazia , Polini Beatrice , Ricardi Caterina , Pignataro Patrizia , Zerlotin Roberta , Oranger Angela , Colucci Silvia , Di Carlo Manuela , Colaianni Graziana , Saba Alessandro , Grano Maria

Introduction: Hypoparathyroidism (HypoPT) is a rare endocrine disease and Post-surgical HypoPT (PS-HypoPT) is the most common cause, caused by accidental parathyroid injury. From a neuropsychological standpoint, patients with PS-HypoPT present cognitive and neuropsychological symptoms. Irisin is a myokine secreted by contracting muscle, which mediates beneficial effects on several targets, including brain. The aim of this study was to evaluate irisin in the context of PS-HypoP...

In silico and ex vivo identification of gonadotropin-related genes involved in ovarian cancer

Lazzaretti Clara , Melli Beatrice , Sperduti Samantha , Perri Carmela , Baschieri Lara , Ylenia Cusenza Vincenza , Martinelli Sandra , Nicoli Davide , Palicelli Andrea , Vincenzo Mandato Dario , Aguzzoli Lorenzo , Simoni Manuela , Casarini Livio

Serous ovarian cancer is one of the leading causes of death among all gynaecological malignancies. Even though a hereditary component has been suggested, most ovarian carcinomas are sporadic and markers for a diagnosis at an early stage of the disease are still to be identified. Since gonadotropins may stimulate the growth of certain cancer cells, we aim to identify tumour markers linked to gonadotropin receptor-mediated pathways. Through an in silico and ex vivo<...

A case report of a patient with severe postoperative hypoparathyroidism

Milotić Marina , Fabris Vitković Daniela , Babarović-Jurišić Mariza , Blagonić Aleksandra , Ferjančić Manuela , Milotic Marina

Beckgrounds and aims: The most common cause of hypoparathyroidism is postoperative, i.e., after thyroid, parathyroid, or radical neck surgery due to neoplasms, and is most often transient, whether continuous or even intermittent. The incidence of permanent hypoparathyroidism ranges from 0.8 to 3.0% in patients after total thyroidectomy. In this case report, we will present a patient with a severe form of postoperative hypoparathyroidism refractory to standard treatment regimen...

Fish oil supplementation during pregnancy attenuates sex-specific changes induced by perinatal maternal high-fat diet in mitochondria of rat skeletal muscle at weaning

Woyames Juliana , Martins Isabela , Souza Manuella , Neto Jessika Oliveira , Andrade Cherley , Atella Georgia , Trevenzoli Isis , Moura Carmen Pazos

Perinatal maternal high-fat (HF) and isocaloric diet induced obesity and metabolic disorders in the offspring since weaning. At adulthood, oxidative soleus skeletal muscle of HF male offspring exhibited lipid accumulation and mitochondrial damage. At birth, HF offspring have higher n-6:n-3 polyunsaturated fatty acids (PUFA) plasma ratio. We hypothesized that HF offspring´s mitochondria of skeletal muscle exhibit damages at weaning that could be mitigated by fish oil (FO, ...
