Retrospective Analysis of Endocrine Dysfunctions in a Population of Adult Polytransfused Patients: Correlation of GH-IGF1 Axis Alteration with Cardiac Performance.

Endocrine complications of haemochromatosis and heart failure mostly affect morbidity and mortality in polytransfused patients. This study analyzes endocrine dysfunctions and the impact of GH-IGF-1 axis alteration on cardiac performance in a population of 31 patients. A retrospective study on 31 Caucasian polytransfused outpatients, 27 adults and 4 pediatric, residing in Apulia, Italy, followed from 2005 to 2016, was conducted.

Glucose targets for preventing diabetic kidney disease and its progression.

Background: Diabetes is the leading cause of end-stage kidney disease (ESKD) around the world. Blood pressure lowering and glucose control are used to reduce diabetes-associated disability including kidney failure. However there is a lack of an overall evidence summary of the optimal target range for blood glucose control to prevent kidney failure.

On the non-linear association between serum uric acid levels and all-cause mortality rate in patients with type 2 diabetes mellitus.

Background And Aims: High levels of serum uric acid (SUA) are associated with increased mortality risk in the general population. Contrasting results are available in people with diabetes. The aim of our study was to investigate the association and its functional form between SUA and all cause-mortality in patients with type 2 diabetes mellitus (T2DM).

Serum resistin is causally related to mortality risk in patients with type 2 diabetes: preliminary evidences from genetic data.

Resistin has been firmly associated with all-cause mortality. We investigated, whether, in patients with type 2 diabetes (T2D), this association is sustained by a cause-effect relationship. A genotype risk score (GRS), created by summing the number of resistin increasing alleles of two genome-wide association studies (GWAS)-derived single nucleotide polymorphisms (SNPs), serum resistin measurements and all-cause death records were obtained in 1,479 (403 events/12,454 person-years), patients with T2D from three cohorts, Gargano Heart Study-prospective design (n = 350), Gargano Mortality Study (n = 698) and Foggia Mortality Study (n = 431), from Italy.

Polyphenol intake and cardiovascular risk factors in a population with type 2 diabetes: The TOSCA.IT study.

Background: The role of polyphenol intake on cardiovascular risk factors is little explored, particularly in people with diabetes.

Aim: To evaluate the association between the intake of total polyphenols and polyphenol classes with the major cardiovascular risk factors in a population with type 2 diabetes.

Methods: Dietary habits were investigated in 2573 males and females participants of the TOSCA.

The PPARγ2 P12A polymorphism is not associated with all-cause mortality in patients with type 2 diabetes mellitus.

The high mortality risk of patients with type 2 diabetes mellitus may well be explained by the several comorbidities and/or complications. Also the intrinsic genetic component predisposing to diabetes might have a role in shaping the risk of diabetes-related mortality. Among type 2 diabetes mellitus SNPs, rs1801282 is of particular interest because (i) it is harbored by peroxisome proliferator-activated receptor-γ2 (PPARγ2), which is the target for thiazolidinediones which are used as antidiabetic drugs, decreasing all-cause mortality in type 2 diabetes mellitus, and (ii) it is associated with insulin resistance and related traits, risk factors for overall mortality in type 2 diabetes mellitus.

The rs12917707 polymorphism at the UMOD locus and glomerular filtration rate in individuals with type 2 diabetes: evidence of heterogeneity across two different European populations.

Background: UMOD variability has been associated at a genome-wide level of statistical significance with glomerular filtration rate (GFR) in Swedish individuals with type 2 diabetes (T2D; n = 4888). Whether this finding is extensible also to diabetic patients from other populations deserves further study. Our aim was to investigate the relationship between UMOD variability and GFR in patients with T2D from Italy.

TRAP1 regulates cell cycle and apoptosis in thyroid carcinoma cells.

Tumor necrosis factor receptor-associated protein 1 (TRAP1) is a heat shock protein 90 (HSP90) molecular chaperone upregulated in several human malignancies and involved in protection from apoptosis and drug resistance, cell cycle progression, cell metabolism and quality control of specific client proteins. TRAP1 role in thyroid carcinoma (TC), still unaddressed at present, was investigated by analyzing its expression in a cohort of 86 human TCs and evaluating its involvement in cancer cell survival and proliferation in vitro Indeed, TRAP1 levels progressively increased from normal peritumoral thyroid gland, to papillary TCs (PTCs), follicular variants of PTCs (FV-PTCs) and poorly differentiated TCs (PDTCs). By contrast, anaplastic thyroid tumors exhibited a dual pattern, the majority being characterized by high TRAP1 levels, while a small subgroup completely negative.

The combined effect of adiponectin and resistin on all-cause mortality in patients with type 2 diabetes: Evidence of synergism with abdominal adiposity.

Background And Aims: While elevated serum adiponectin and resistin levels have been singly associated with all-cause mortality in patients with type 2 diabetes (T2D), their combined effect has never been studied. We investigated such joint effect in patients with T2D and its possible modulation by several demographic and clinical conditions, known to affect per se mortality rate.

Methods: Patients with T2D from the Gargano Mortality Study (GMS; N = 895, follow-up = 10.

The paradoxical association of adiponectin with mortality rate in patients with type 2 diabetes: evidence of synergism with kidney function.

Background: The paradoxical relationship between high adiponectin and increased mortality, described in several clinical subsets, has been reported only once in type 2 diabetes (T2D) and only in selected elderly patients. We investigated this relationship in unselected patients with T2D and, then, addressed its possible modulation by several demographic and clinical conditions, known to affect per se mortality rate.

Methods: Patients from the Gargano Mortality Study (GMS; N = 897, follow-up = 10.

/ mutational status in familial non-medullary thyroid carcinomas: A retrospective study.

There are contrasting views on whether familial non-medullary thyroid carcinomas (FNMTCs) are characterized by aggressive behavior, and limited evidence exists on the prognostic value of and mutations in these tumors. Thus, in the present study, clinicopathological features were analyzed in 386 non-medullary thyroid carcinomas (NMTCs), subdivided in 82 familial and 304 sporadic cases. Furthermore, the and mutational statuses were investigated in a subgroup of 34 FNMTCs to address their clinical and biological significance.

Serum Adiponectin and Glomerular Filtration Rate in Patients with Type 2 Diabetes.

High serum adiponectin has been increased in several conditions of kidney disease. Only sparse and conflicting results have been reported in patients with type 2 diabetes (T2D), a subgroup of individuals who are at high risk for renal dysfunction. The aim of this study was to fill up this gap of knowledge by investigating such association in a large sample of Italian diabetic patients.

Target values of cardiovascular risk factors are not associated with all-cause mortality in patients with type 2 diabetes mellitus.

Background: To investigate prospectively the relationship between target values of glycated hemoglobin, blood pressure and LDL-cholesterol, as considered in a combined fashion, and all-cause mortality in patients with type 2 diabetes mellitus.

Methods: Two cohorts of patients with type 2 diabetes mellitus, the Gargano Mortality Study (n=810) and the Foggia Mortality Study (n=929), were investigated. A weighted target risk score was built as a weight linear combination of the recommended targets reached by each patient.

Mitotane and Carney Complex: ten years follow-up of a low-dose mitotane regimen inducing a sustained correction of hypercortisolism.

Objective: Primary pigmented nodular adrenocortical disease (PPNAD), an uncommon cause of Cushing's syndrome, is frequently associated with a wider clinical spectrum, the Carney complex (CC), a multiple endocrine neoplasia syndrome.

Design: We evaluated a low-dose mitotane regimen for treating severe hypercortisolism in a 27-year-old woman with CC. She presented with severe hypercortisolism and a history of surgeries for breast ductal adenoma, atrial cardiac myxomas with cerebral and peripheral arterial embolism, and near-total thyroidectomy because of an oxyphilic adenoma.

A novel mutation in calcium-sensing receptor gene associated to hypercalcemia and hypercalciuria.

Background: Familial Hyperparathyroidism (HPT) and Familial benign Hypocalciuric Hypercalcemia (FHH) are the most common causes of hereditary hypercalcemia. FHH has been demonstrated to be caused by inactivating mutations of calcium-sensing receptor (CaSR) gene, involved in PTH regulation as well as in renal calcium excretion.

Case Presentation: In two individuals, father and son, we found a novel heterozygous mutation in CaSR gene.

IRS1 G972R missense polymorphism is associated with failure to oral antidiabetes drugs in white patients with type 2 diabetes from Italy.

This study tried to replicate in a large sample of white patients with type 2 diabetes (T2D) from Italy a previously reported association of the IRS1 G972R polymorphism with failure to oral antidiabetes drugs (OAD). A total of 2,409 patients from four independent studies were investigated. Case subjects (n = 1,193) were patients in whom, because of uncontrolled diabetes (i.

The role of survivin in thyroid tumors: differences of expression in well-differentiated, non-well-differentiated, and anaplastic thyroid cancers.

Background: Survivin is involved in human cancer and is responsible for aggressive biological behavior and poor clinical outcomes in several human malignancies. Thus, we hypothesized that the upregulation of survivin protein expression may be enhanced in parallel with transition toward a poorly differentiated phenotype in human thyroid carcinomas.

Methods: The expression of survivin was evaluated, using a standard linked streptavidin-biotin horseradish peroxidase technique technique, in a series of 56 human thyroid carcinomas (42 papillary, 4 poorly differentiated, and 10 anaplastic carcinomas) and thyroid carcinoma cell lines at different degrees of differentiation.

The IRS1 G972R polymorphism and glomerular filtration rate in patients with type 2 diabetes of European ancestry.

Background: In Mexican Americans, the IRS1 G972R polymorphism (rs1801278) has been associated to such a marked reduction in glomerular filtration rate (GFR) (i.e. β = -8.

Age, renal dysfunction, cardiovascular disease, and antihyperglycemic treatment in type 2 diabetes mellitus: findings from the Renal Insufficiency and Cardiovascular Events Italian Multicenter Study.

Objectives: To assess the distribution of antihyperglycemic treatments according to age and renal function and its relationship with cardiovascular disease in type 2 diabetes mellitus (T2DM).

Design: Cross-sectional analysis.

Setting: Nineteen hospital-based diabetes mellitus clinics in 2007 and 2008.

Development and validation of a predicting model of all-cause mortality in patients with type 2 diabetes.

Objective: To develop and validate a parsimonious model for predicting short-term all-cause mortality in patients with type 2 diabetes mellitus (T2DM).

Research Design And Methods: Two cohorts of patients with T2DM were investigated. The Gargano Mortality Study (GMS, n = 679 patients) was the training set and the Foggia Mortality Study (FMS, n = 936 patients) represented the validation sample.

The 9p21 coronary artery disease locus and kidney dysfunction in patients with Type 2 diabetes mellitus.

Background: We investigated whether the coronary artery disease (CAD) locus on chromosome 9p21 (as represented by single nucleotide polymorphism rs2383206) is associated with low estimated glomerular filtration rate (eGFR) or increased urinary albumin excretion in patients with Type 2 diabetes mellitus (T2DM).

Methods: Four samples, including a total of 3167 patients, were studied. The presence of low eGFR (<60 mL/min/1.

Activation of the RAS/RAF/ERK signaling pathway contributes to resistance to sunitinib in thyroid carcinoma cell lines.

Context: Sunitinib is currently being evaluated in advanced human thyroid carcinomas, based on the rationale that the vascular endothelial growth factor and platelet-derived growth factor receptors and the RET/PTC rearrangement are valuable targets for the treatment of this malignancy. However, criteria for selecting thyroid tumors that may benefit from sunitinib are lacking.

Design: The effect of activating somatic mutations in the KRAS and BRAF genes on the responsiveness to sunitinib was evaluated in a panel of thyroid cancer cell lines harboring wild-type KRAS and BRAF genes, the RET/PTC1 rearrangement, the G12R KRAS, or the V600E BRAF mutation.

Diverging association of reduced glomerular filtration rate and albuminuria with coronary and noncoronary events in patients with type 2 diabetes: the renal insufficiency and cardiovascular events (RIACE) Italian multicenter study.

Objective: Although a reduced estimated glomerular filtration rate (eGFR) was shown to be a powerful independent predictor of cardiovascular disease (CVD), other studies suggested that it confers a much lower risk than albuminuria alone, whereas the combination of the two abnormalities is associated with multiplicative risk. This study aimed at assessing the independent association of previous CVD events, either total or by vascular bed, with eGFR and albuminuria and chronic kidney disease (CKD) phenotypes.

Research Design And Methods: This cross-sectional study evaluated 15,773 patients with type 2 diabetes from the Renal Insufficiency And Cardiovascular Events (RIACE) Italian Multicenter Study in 19 outpatient diabetes clinics in years 2007-2008.

Epidermal growth factor receptor 1 expression is upregulated in undifferentiated thyroid carcinomas in humans.

Background: Epidermal growth factor receptor 1 (EGFR1) signaling is involved in human cancer cell progression and is responsible for aggressive biological behavior and poor clinical outcome in several human malignancies. Activation of the EGFR1 pathway has been proposed, among others, as being involved in the progression of thyroid cancer toward a thyroid-stimulating hormone (TSH)-independent phenotype. We have previously observed that undifferentiated thyroid carcinoma cells are hyper-sensitive to EGF signaling of downstream intracellular pathways, and this correlated both with the loss of TSH-dependency and increase in EGF-dependent proliferation and migration.
