Aim: To evaluate the use of PET/CT with 64CuCl2 in recurring prostate cancer after surgery in patients with low PSA level (<2).Introduction: Previous works* demonstrated as 64CuCl2 is a PET probe in prostate cancer in mice with xenografts of prostate cancer.Moreover, it was described** in seven patients the role of 64CuCl2 PET/CT in staging of prostate cancer.Met...

Thyroid malignancies are the most common type of endocrine tumors. Of the various histological sub-types, anaplastic thyroid carcinoma (ATC) represents 2% of all cases but is responsible for most of the thyroid cancer related death.Indeed, ATC is regarded as one of the more aggressive and hard to treat forms of human cancer. Moreover, to date, there is a paucity of relevant models to study how the signature genetic abnormalities detected in ATC contribut...

Objective(S): Single nucleotide polymorphism (SNP) in endothelial nitric oxide synthase (eNOS) G894T may affect the oxidative stress response. Our objective was to examine G894T SNP eNOS genotype frequencies and its potential role with sperm motility in infertile men. Through this prospective controlled study in the Andrology Unit, we have enrolled infertile (n=70) and healthy (n=60) men. Sperm motion kinetics assessed by computer assisted semen analysis (CASA), ...

Background: Hypothyroidism (HT) has been demonstrated to be associated to heart failure (HF) progression.Aim of the study: To evaluate the impact of HT on the progression of HF during a long-term follow-up.Methods: From 2006 to 2015, we evaluated 675 consecutive CHF outpatients (523 males, 64±13 years) in stable clinical conditions (>1 month) and in conventional therapy. They underwent a clinical evaluation, 12-lead ECG, e...

Introduction: The new Italian cytological classification of thyroid nodules published in 2014 has replaced the TIR3 ‘indeterminate’ category into two subcategory with different risk of thyroid cancer (TC): TIR3A, low-risk indeterminate lesion and TIR3B, high-risk indeterminate lesion. The aim of our study was to describe the incidence of TIR3B in a large prospective cohort of patients, the risk of TC, and its correlation with anamnestic, ultrasonographic (US) and cyt...

Background: Hypothyroidism and low T3 syndrome frequently occur in HF patients.Aim of the study: To evaluate in a large sample of CHF patients the association between thyroid hormone deficiencies and poor outcome.Methods and results: From 2006 to 2015, we screened 712 consecutive CHF outpatients (551 males, 64±14 years, left ventricular ejection fraction (LVEF) 33±10%, NYHA class 2.3±0.6, NTproBNP 2153±4696 pg/m...

Background: It has been previously demonstrated that thyroid hormone deficiency is associated with a worse outcome in patients affected by chronic heart failure (CHF). However, few data are available about the effects of thyroid replacement therapy on the prognosis of patients.Aim of the study: The aim of the study was to evaluate the relationship among thyroid replacement therapy, correction of thyroid stimulating hormone (TSH) serum levels and outcome ...

Mechanisms regulating the selection of antral ovarian follicles are poorly understood and supposed to rely on low estrogen levels, decline of follicle-stimulating hormone (FSH) levels and receptor (FSHR) expression on the surface of granulosa cells. These concepts are challenged in-vitro, where apoptosis of human granulosa cells (hGLC) and transfected cell lines is induced by high doses of FSH or FSHR overexpression, while estrogens induce anti-apoptotic signals via n...

Background: Variations in gut microbiota might impact metabolic functions like caloric intake and energy expenditure leading to body weight excess. Microbiota modulation may be a potential approach for obesity management, especially in subject characterized by specific microbial enterotypes.Objective: We aimed to assess the impact of probiotic treatment in obese children and adolescents, under diet control, on weight loss, glucose, and insulin homeostasi...
