GH deficiency (GHD) negatively influences cardiovascular function directly by impairing cardiac filling, performance, and contractility and indirectly by inducing atherosclerotic changes, hypercoagulability, abdominal obesity, insulin resistance, dislipidemia, endothelial dysfunction, etc. This accounts for the reduced life expectancy and increased risk of death for vascular disease in these patients.CFR represents the capacity of the coronary circulatio...

The increasing use of somatostatin (SRIF) analogues prompted extensive investigations on SRIF receptor (SSR) in human tumours. Human prostate cancer (PCa) may differentially express SSRs from the normal tissue. Moreover, SSR and dopamine (D) receptors (DR) may interact to form homo- and heterodimers with enhanced functional activity. In the present study, using the human androgen-dependent PCa cell line LNCaP, we investigated: 1) SSR and DR subtype expression in different cult...

Somatostatin (SRIF) has been demonstrated to inhibit in vitro proliferation of normal and transformed cells via SRIF receptors (SSRs). Moreover, like other neuroendocrine molecules, SRIF and SSRs may play a significant role in the progression and neuroendocrine differentiation of human prostate cancer (PCa). However, conflicting results have been reported in the literature on SSR heterogeneity and specific cell localization in PCa. In the present study, using the human ...

Growth is an integrated process, resulting from the response of cells to nutrient availability and to hormonal status. Nutrients, in turn, are important regulators of IGF-IGFBP system which are critical regulators of growth. Genetic factors seem to be very important determinant of final stature in countries with high quality of life at variance with underprivileged countries where food intake deficiency is critical. The aim of our study was to evaluate the influence of environ...

Background: 131I-norcholesterol scintigraphy (INCS) is currently not considered a main confirmatory and localizing study in primary aldosteronism (PA), however few recent data is available. On the other hand, adrenal venous sampling (AVS) is technically difficult, and may also lead to erroneuos diagnosis.Aim: To describe the performance of INCS, done under dexamethasone (DXM) supression, in daily practice.Patients and methods: Retr...

Background: Evidence has shown that the use of high doses of statins is associated with lower levels of LDL cholesterol and a decrease in cardiovascular events. Likewise, the use of high doses of statins may increase the risk of myopathy, elevation of liver enzymes, renal failure and cognitive alterations. We conducted a systematic review with a meta-analysis of all RCTs investigating the impact of atorvastatin and ezetimibe therapy on levels of LDL cholesterol vs high doses o...

Background: Despite a high relapse rate, antithyroid drugs (ATDs) remain the first-line therapy of Graves’ disease (GD). Long-term follow-up studies of GD in Spain are scarce. Our aims were to identify clinical differences between patients who relapsed vs those who attained remission and to describe the relapse rate of GD after ATD withdrawal.Methods: We analyzed patients with the first episode of GD who were treated with ATDs during 2010 - 2020, in...

Background: Patients with neuroendocrine tumours (NETs) and acromegaly are commonly treated with somatostatin analogs (SSAs), such as octreotide and lanreotide depot formulations. The Pharmathen syringe is now available in several European countries and the USA for lanreotide depot injection. When using SSAs, confidence in and ease of use with syringes are important for decision-making in long-term therapy. The aim of the PRESTO 3 study was to compare nurses’ preference f...

Background: Acromegaly is a rare disorder associated with excessive levels of growth hormone(GH) and insulin-like growth factor-1(IGF-1). GH/IGF-1 excess leads to morphologic craniofacial and acral changes as well as cardiometabolic complications, but the phenotypic changes and presentation differ across species.Aim: To present the resemblances and distinctive features of acromegaly in humans, cats and dogs.Methods: A literature re...

Introduction: Percutaneous ethanol injection (PEI) or thyroid enolisation is a minimally invasive technique applicable to benign cystic thyroid nodules, not adhered to neighbouring structures, due to local compressive symptoms or aesthetic discomfort. Classically, the treatment of choice for these nodules has been simple aspiration, followed by surgery in refractory cases. Currently, PEI has emerged as an alternative to surgery due to its high efficacy, speed, safety, low rate...
