BACKGROUND AND OBJECTIVES In Italy, typical HFE mutations account for only 64% of the cases with overt hereditary hemochromatosis (HH), and a common HFE-unrelated disease was hypothesized. DESIGN AND METHODS One thousand and fifty potential blood donors were screened by iron tests, C282Y and H63D HFE mutation analysis in a region in North Italy. Subjects with repeated fasting transferrin satu...

Background: Cardiac complications due to iron overload are the most common cause of death in patients with thalassemia major. The aim of this study was to compare iron chelation effects of deferoxamine, deferasirox, and combination of deferoxamine and deferiprone on cardiac and liver iron load measured by T2* MRI. Methods: In this study, 108 patients with thalassemia major aged over 10 years...

BACKGROUND Iron overload can affect cardiac structure and function by the production of free radicals in addition to iron deposits in heart muscle. The purpose of this study was to compare traditional and non-traditional cardiovascular risk factors (CVRF) in children and adolescents on renal replacement with and without iron overload. Also, we evaluated the relationships between iron overload a...

For most computer systems, even short periods of overload degrade performance signi cantly. The number of jobs in the system quickly grows, often exceeding the capacity of the system within just seconds, and response times explode. In this paper we investigate system behavior under transient overload. We nd that the poor behavior of systems under transient overload can at least partly be attrib...

INTRODUCTION Fluid overload is a clinical problem frequently related to cardiac and renal dysfunction. The aim of this study was to evaluate fluid overload and changes in serum creatinine as predictors of cardiovascular mortality and morbidity after cardiac surgery. METHODS Patients submitted to heart surgery were prospectively enrolled in this study from September 2010 through August 2011. C...

OBJECTIVE Recent evidence suggests that fluid overload may be deleterious to critically ill children. The purpose of this study was to investigate the association of early fluid overload with respiratory morbidity and mortality in patients admitted to a general PICU. DESIGN Retrospective cohort study. SETTING Single, tertiary referral PICU. PATIENTS SIX HUNDRED THIRTY-SIX patients aged 0-...

Knowledge of the molecular mechanisms by which skeletal muscle hypertrophies in response to increased mechanical loading may lead to the discovery of novel treatment strategies for muscle wasting and frailty. To gain insight into potential early signaling mechanisms associated with skeletal muscle hypertrophy, the temporal pattern of mitogen-activated protein kinase (MAPK) phosphorylation and p...

Nineteen children and adolescents receiving repeated transfusions and subcutaneous desferrioxamine treatment were investigated in an attempt to quantitate iron overload non-invasively. Before patients were started on desferrioxamine individual relationships were correlated for 12 to 36 months between transfused iron, absorbed iron estimated gastrointestinally, and increasing serum ferritin conc...

Iron overload, caused by hereditary hemochromatosis or repeated blood transfusions in some diseases, such as beta thalassemia, bone marrow failure and myelodysplastic syndrome, can significantly induce injured bone marrow (BM) function as well as parenchyma organ dysfunctions. However, the effect of iron overload and its mechanism remain elusive. In this study, we investigated the effects of ir...

RATIONALE Pressure overload induces adaptive remodeling processes in the heart. However, when pressure overload persists, adaptive changes turn into maladaptive alterations leading to cardiac hypertrophy and heart failure. ATF3 is a stress inducible transcription factor that is transiently expressed following neuroendocrine stimulation. However, its role in chronic pressure overload dependent c...
