In heart failure with reduced ejection fraction, catabolic mechanisms have a strong negative impact on mortality and morbidity. The relationship between anabolic hormonal deficiency and heart failure with preserved ejection fraction (HFpEF) has still been poorly investigated. On the other hand, oxidative stress is recognized as a player in the pathogenesis of HFpEF. Therefore, we performed a cohort study in HFpEF in order to: 1) define the multi-hormonal deficiency prevalence ...

Sertoli cells are the most active cell population in the prepubertal testis. During infancy and childhood, male hypogonadism can be evidenced by assessing Sertoli cell function without the need for stimulation tests. Anti-Müllerian hormone (AMH) is a distinctive serum marker of the prepubertal Sertoli cell, which is high from foetal life until puberty. AMH production is stimulated by FSH and potently inhibited by androgens. Initially used only to distinguish between patie...

Diabetic ketoacidosis (DK) is one of the most serious complications of diabetes mellitus (DM). We performed a case review of DK patients admitted to the intensive care unit (ICU) of our Hospital between 1 June 2012 and 30 June 2016. A demographic analysis was made, time of DM evolution, the therapy and the factors that led to its decompensation. Thus, a total of 42 DK patients were admitted to the ICU in the referred period, mean age was 45 years, a clear predominance of femal...

Diabetic ketoacidosis (DKA) is one of the most serious complications of diabetes mellitus (DM). We describe 2 cases of type-2 diabetic patients admitted by a surgical reason/trauma in which DM control was neglected. We present a 74-year-old patient with poor metabolic control (HbA1c 7,6%) treated with metphormin, sitagliptin and glibenclamide, admitted for orthopaedic surgery. During hospitalization, there were noted several episodes of disorientation with hyperglycae...

Background: Adult growth hormone deficiency (AGHD) has been increasingly observed among patients with traumatic brain injury, stroke, and central nervous system infection, aside from the subgroup of patients with pituitary tumors. When left untreated, these patients have a significantly increased risk to develop cardiovascular morbidity and mortality and impaired psychosocial function. Existing treatment guidelines on AGHD have recommended the use of growth hormone (GH) replac...

Aim: Stimulated thyroglobulin (sTg), measured at radioiodine remnant-ablation (RRA) in patients with differentiated thyroid cancer(DTC), is an important predictive factor of persistent disease. However, Tg produced by normal thyroid cells may also contribute to the sTg value.We aimed to study the relationship between sTg-level in RRA and the thyroid remnant size (TRs), using post-therapy whole-body scan (131I-ptWBS), at different TSH stimulation method.<...

Parathyroid carcinoma (PC) is very rare and difficult to differentiate from atypical parathyroid adenoma (AA). En-bloc surgical resection is recommended, but most cases are diagnosed after non-radical surgery, and it is recommended to expand it. Given the rarity of the cases, the difficulty in the histological diagnosis (HD) and the unpredictability of the evolution, we analyzed our experience with PC and AA.Material and methods: We conducted a ...

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...

Background: Advanced neuroendocrine tumors (NETs) are associated with poor prognoses. A 4-dose regimen of lutetium Lu 177 (177Lu)-DOTATATE has been shown to improve progression-free survival (PFS) and overall survival (OS) in patients with advanced NETs. This is the first United States (US) study to evaluate the effectiveness and safety of additional doses in patients with progressive NETs.Methods: This was a retrospective chart review of 31 a...

It has been suggested that the selective m-TOR inhibitor, Rapamycin, has been improved the success pancreatic islet allotransplantation (ITx) in type 1 diabetic patients (T1DM). Forty-one ITx were studied. Thirteen T1DM in poor glycemic control underwent a 45-days Rapamycin before ITx followed by standard Edmonton Protocol (EP, group 1, Milan), and they were compared to 28 T1DM patients undergoing EP (group 2, Miami). Outcome measures were daily insulin requirement (DIR), HbA1...
