The blue glow of the mucus from Chaetopterus involves a photoprotein, iron and flavins. Identity and respective role of these components remain, however, largely unresolved today, likely because of viscosity issues and inhibition of this system by oxidizers conventionally used to track bioluminescence activity. Here, we used gentle centrifugation to obtain a mucus supernatant showing no inhibition to oxidizers, allowing for further analysis. We applied conventional chromatographic techniques to isolate major proteins associated with light emission...

Anemia is an independent risk factor for adverse patient outcomes. There are no guidelines for management of anemia in patients withcongestive heart failure (CHF), despite itshigh incidence. Four objectives were defined by the International Anemia Management and Clinical Outcomes Expert Panel (AMCO), a multinational group of interdisciplinary experts identified by the Society for the Advancement of Blood Management (SABM) to: determine the prevalence of anemia in outpatients; to determine the prevalence of hospital-acquired anemia; to assess the impact of anemia management on clinical outcomes such as quality of life and functional status; and to provide recommendations for primary care physicians and specialists for the diagnosis, evaluation, and management of anemia in patients with CHF...

Anthracycline-induced cardiotoxicity (ACT) is a severe complication in children and young adults that may lead to congestive heart failure. Some risk factors have been identified: high anthracycline cumulative dose, high radiation dose delivered on the cardiac area, or young age during the treatment. Primary prevention is not clearly defined in children. The dexrazoxane iron chelator seems to be interesting based on its short-term cardioprotective property in patients receiving doxorubicin-containing regimens...

BACKGROUND: While transfusion and iron chelation therapy for thalassemia major (TM) has improved dramatically in recent years, the consequences of this improvement (current rates of survival and TM-related complications) remain unknown. METHODS: This nationwide population-based cohort study analyzed 2007-2011 data obtained from the Taiwanese National Health Insurance Research Database. RESULTS: After excluding those patients receiving hematopoietic stem cell transplantation, we enrolled 454 patients with TM who received transfusion and chelation therapy (median age, 17...

PURPOSE OF REVIEW: Loss of skeletal muscle oxidative capacity is a common feature of chronic diseases such as chronic obstructive pulmonary disease, type 2 diabetes, and congestive heart failure. It may lead to physical impairments and has been suggested to contribute to metabolic inflexibility-induced cardiometabolic risk. The mechanism underlying loss of muscle oxidative capacity is incompletely understood. This review discusses the role of mitophagy as a driving force behind the loss of skeletal muscle oxidative capacity in these patients...

INTRODUCTION: Iron deficiency in congestive heart failure (CHF), with or without concomitant anaemia, is associated with health-related quality of life, NYHA functional class, and exercise capacity. Prospective, randomised studies have demonstrated that correcting iron deficiency improves the quality of life and functional status of patients with CHF, including those who do not have anaemia. OBJECTIVE: The aim of this study was to analyse how frequently these iron parameters are tested and thus determine the extent to which this quality improvement tool has been implemented in patients admitted with CHF...

PHD3 belongs to the family of 2-oxoglutarate and iron-dependent dioxygenases and is a critical regulator of HIF-1α. Its expression is increased in cardiovascular diseases such as cardiomyopathy, myocardial ischemia-reperfusion injury, and congestive heart failure. However, the association between PHD3 and atherosclerosis has not been clearly elucidated. In the present study, we investigated the potential effect and mechanism of PHD3 in apolipoprotein E-deficient (ApoE-/-) mice. Murine PHD3 lentivirus and shRNA -PHD3 lentivirus were constructed and injected intravenously into ApoE-/- mice fed on a high fat diet...

Chronic kidney disease (CKD), cardiac damage (CD) and the combination of the two are associated with increased morbidity and death in patients admitted to vascular surgery units. We assessed the prevalence of cardiac and renal damage and cardiorenal syndrome (CRS) in 563 patients with abdominal aortic aneurysms (AAA) who underwent cardiac screening before either an endovascular procedure (EVAR) or open surgery (OS) for aneurysm repair. CD was defined by ≥stage B as per the ACC/AHA classification of congestive heart failure (CHF), while CKD was defined by estimated GFR <60 mL/min/1...

Cardiotoxicity is a serious complication of anticancer therapy by anthracycline antibiotics. Except for intercalation into DNA/RNA structure, inhibition of DNA-topoisomerase and histone eviction from chromatin, the main mechanism of their action is iron-mediated formation of various forms of free radicals, which leads to irreversible damage to cancer cells. The most serious adverse effect of anthracyclines is, thus, cardiomyopathy leading to congestive heart failure, which is caused by the same mechanisms. Here, we briefly summarize the basic types of free radicals formed by anthracyclines and the main processes how to scavenge them...

Renal anemia is caused by the deficiency of endogenous erythropoietin (Epo) due to renal dysfunction. We think that it is possible to slow the progression of chronic kidney disease (CKD) in case we initiate Epo early in pre-dialysis patients, especially in the non-diabetic population. Erythropoiesis stimulating agent (ESA) treatments targeting mild anemia (10-12 g/dl) can decrease the risk of occurrence of cardiovascular disease (CVD) in patients with hypertension, diabetes mellitus and congestive heart failure...

Iron deficiency and anaemia occur frequently in patients with chronic kidney disease (CKD) or chronic heart failure (CHF) and are associated with lower quality of life and higher mortality. Treating anaemia with erythropoietic growth factors produces no improvement. In recent years, the focus has therefore shifted to correction of iron deficiency. Chronic inflammation in CKD increases the production of hepcidin, which blocks iron absorption from the intestine and leads to less efficient re-use of iron from the macrophages...

OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is a major cause of morbidity and mortality. Iron deficiency, with or without anaemia, is associated with other chronic conditions, such as congestive heart failure, where it predicts a worse outcome. However, the prevalence of iron deficiency in COPD is unknown. This observational study aimed to determine the prevalence of iron deficiency in COPD and associations with differences in clinical phenotype. SETTING: University hospital outpatient clinic...

OBJECTIVE: In chronic kidney disease (CKD), both anemia and deregulated phosphate metabolism are common and predictive of adverse outcome. Previous studies suggest that iron status influences phosphate metabolism by modulating proteolytic cleavage of FGF23 into C-terminal fragments. Red cell distribution width (RDW) was recently identified as a strong prognostic determinant for cardiovascular morbidity and mortality, independently of iron status. We assessed whether RDW is associated with FGF23 cleaving in CKD patients with heart failure...

OBJECTIVE: For patients with chronic heart failure (CHF), exertional fatigue is one of the most common and debilitating symptoms. However, the poor relationship between heart dysfunction and exercise capacity has been ascribed to peripheral abnormalities. Several previous studies confirmed that iron supplementation could significantly improve the exercise capacity of patients with CHF, although they did not analyze effects in the musculoskeletal system. The aim of this study was to investigate the effect of iron treatment on gastrocnemius muscles of CHF rats with anemia...

Anticancer drugs continue to cause significant reductions in left ventricular ejection fraction resulting in congestive heart failure. The best-known cardiotoxic agents are anthracyclines (ANTHs) such as doxorubicin (DOX). For several decades cardiotoxicity was almost exclusively associated with ANTHs, for which cumulative dose-related cardiac damage was the use-limiting step. Human epidermal growth factor (EGF) receptor 2 (HER2; ErbB2) has been identified as an important target for breast cancer. Trastuzumab (TRZ), a humanized anti-HER2 monoclonal antibody, is currently recommended as first-line treatment for patients with metastatic HER2(+) tumors...

BACKGROUND: Growth differentiation factor (GDF) 15 was recently identified as a hepcidin-suppression factor that is expressed at high levels in patients with ineffective erythropoiesis. Hepcidin is a small defensin-like peptide whose production by hepatocytes is modulated in response to anemia, hypoxia, or inflammation. The aim of this study was to assess GDF15 levels and its correlation with iron parameters in 134 stable heart transplant recipients compared with 157 patients with chronic heart failure (CHF)...
