PURPOSE: Patients undergoing cardiac surgery with extracorporeal circulation (ECC) frequently present haemorrhages as a complication associated with high morbidity and mortality. One of the factors that influences this risk is the volume of blood infused during surgery. The objective of this study was to determine the optimal volume of autologous blood that can be processed during cardiac surgery with ECC. We also determined the number of salvaged red blood cells to be reinfused into the patient in order to minimize the risk of haemorrhage in the postoperative period...

Hypothyroidism, characterised by low/normal free thyroxine (FT4) and free tri-iodothyronine (FT3) with elevated thyroid-stimulating hormone (TSH), is a well-known complication of nephrotic syndrome (NS). This is a common feature of primary and secondary glomerular diseases and comprises loss of protein in the urine and increased urinary excretion of thyroid hormones and thyroxine-binding globulin. With a normal thyroid reserve, this scenario is associated with the development of subclinical hypothyroidism, with a slight increase in TSH and normal free fractions...

Matrix metalloproteinases (MMPs) are zinc-dependent proteases that degrade components of the extracellular matrix (ECM). In glomerular disease, MMPs are major regulators of ECM degradation as well as structural and functional integrity in the glomerulus. In altered matrix composition diseases, glomerular damage is due to increased degradation of kidney and vessel basement membranes (BMs) by MMPs. MMP -2 and -9 are both considered as the main enzymes that degrade collagen type-IV (coll-IV), which represents the key collagenous component of ECM and constitutes the architectural structure of vessels and glomerular BM...

BACKGROUND AND OBJECTIVES: Obesity is often associated with insulin resistance (IR). We considered different IR indexes: the Homeostasis Model Assessment-Insulin Resistance (HOMA-IR) index, the two specimen (0 and 120 min) oral glucose tolerance test Matsuda Index (MI) and the Homeostasis Model Assessment-Adiponectin (HOMA-AD) index. These IR indexes were compared with indicators of the cardiometabolic profile. METHOD: This cross-sectional study enrolled 60 obese individuals without previous history of diabetes...

BACKGROUND: Abdominal aortic aneurysm (AAA) formation is associated with by inflammation and matrix degradation. This study tested the hypothesis that calprotectin, a novel biomarker for inflammation, as well as established biomarkers such as C-reactive protein (CRP) and matrix metalloproteinase-9 (MMP-9) could also be indicative inflammatory biomarkers during AAA pathogenesis and progression. We also evaluated the correlation of serum soluble Receptor for Advanced Glycation End Products (sRAGE) with AAA diameter and serum calprotectin levels...

Ischaemic stroke in young adults encompasses approximately 5 - 15% of all ischaemic strokes, depending on the selected upper age limit. The key features of the disease, including incidence, risk factors, underlying causes, mortality, outcomes, as well as long-term risks of recurrent events are different from those for elderly patients. There is also evidence indicating that these characteristics may differ ethnically and geographically. It is clinically important to recognize such differences not only for correct diagnosis and treatment, but also for introducing accurate preventive measures...

Despite recent advances, there is still an unmet need in antithrombotic therapy. New drugs have to overcome old targets, looking for new complementary strategies to counteract thrombus formation and propagation. Since its initial recognition in the 50's, von Willebrand Factor (VWF) has proved to be a contributor in clot formation. The contribution of VWF to platelet adhesion and aggregation is pivotal at high shear rates (i.e. microcirculation and critical artery stenosis), where globular-inactive-VWF elongates in a long chain-active conformation...

Arterial stiffness, the expression of reduced arterial elasticity, is an effective predictor of cardiovascular disorders. Oxidative stress is an imbalance between exposure to toxic reactive oxygen species (ROS) and antioxidant systems. The increase in reactive nitrogen species (RNS) is termed nitrosative stress. We review the main mechanisms and products linking arterial stiffness with oxidative and nitrosative stress in several disorders, focusing on recent experimental and clinical data, and the mechanisms explaining benefits of antioxidant therapy...

Pulmonary hypertension (PH) is a severe disease characterized by a progressive increase in pulmonary vascular resistance, initially due to abnormal pulmonary vasoconstriction in response to endothelial and smooth muscle cells injury. The discovery of new chemical entities having a protective effect on pulmonary artery cells could be meaningful for the treatment of PH. We evaluated the protective effect of DL0805 derivatives (DL0805-1 and DL0805-2) on pulmonary artery vascular cells, including human pulmonary artery endothelial cells (HPAECs) and human pulmonary artery smooth muscle cells (HPASMCs)...

Yi Fu, Wei Kong
Cardiovascular (CV) diseases remain a leading cause of morbidity and mortality in the world. Increasing the understanding of the pathogenesis of various CV diseases may provide novel therapeutic targets to improve their prevention and treatment. Cartilage oligomeric matrix protein (COMP), also known as thrombospondin-5 (TSP-5), is a matricellular protein that is abundantly expressed in both cartilage and the CV system. Our group and others have identified COMP as playing critical roles in maintaining CV homeostasis...

Chronic ethanol (EtOH) consumption has been associated with deleterious effects on the cardiovascular system by abnormal calcium (Ca²⁺) handling. Store-operated Ca2+ entry (SOCE) is related to cardiovascular remodeling which leads to the hypertension development, and the coupling between STIM-1 (ER Ca2+ sensor) and Orai-1 (channel pore) is a key mechanism to control SOCE through of store-operated Ca2+ channels (SOCCs). However, the role of STIM-1/Orai-1-mediated SOCE and its cross-talk with EtOH-triggered vascular remodeling and hypertension remain poorly understood...

Cells constantly adapt to external humoral cues like cytokines and hormones, but practically most cellular behavior is under locally guided control via cell-cell interactions. Galectins (Gals) are one of the most prominent members of the group of molecules involved in this intercellular signaling. They are the family of β-galactoside specific lectins and consist of 15 different types, each with a specific function. They play crucial role in the immune system, inflammation, wound healing and carcinogenesis...

Add-on mineralocorticoid-receptor-antagonists (MRAs) spironolactone and eplerenone can enhance the cardioprotective action of angiotensin-converting-enzyme-inhibitors (ACEIs), angiotensin-receptor-blockers (ARBs) and/or β-blockers in non-dialysis patients with congestive heart failure (CHF) and reduced left ventricular (LV) ejection fraction. The efficacy and safety of MRAs among patients on chronic dialysis is less well studied. A growing body of evidence derived from small randomized studies suggests that MRA therapy may improve a number of surrogate cardiovascular (CV) risk factors (i...

Patients with diabetes usually exhibit diabetic dyslipidaemia. The aim of the review is to present the quantitative and qualitative alterations of lipids and lipoproteins and the associated mechanisms in patients with diabetic dyslipidaemia. The main quantitative changes observed in patients with diabetic dyslipidaemia are increased triglycerides and decreased high-density lipoprotein (HDL) cholesterol levels. Qualitative abnormalities mainly include increased small dense low-density lipoprotein particles (despite similar serum low-density lipoprotein cholesterol levels as non-diabetic subjects) and alterations in the apolipoprotein content of HDL particles...

The beneficial effects of chronic exercise training on lipoprotein metabolism include a considerable increase in serum high density lipoprotein-cholesterol and a reduction in serum triglyceride levels. These changes are mostly reported in athletes participating in dynamic sports, especially in the endurance ones. Diagnosis and treatment of dyslipidaemias in athletes should follow the main principles of management of dyslipidaemias for the general population, while specific considerations for athletes should be taken into account...

BACKGROUND: The clinical manifestations of acute heart failure (AHF) and respiratory infection (RI) frequently overlap in patients presenting with dyspnoea at the emergency department (ED). The neutrophil to lymphocyte (N/L) and platelet to lymphocyte (P/L) ratios have been proposed as diagnostic and prognostic indices in this setting. OBJECTIVE: To evaluate the ability of N/L and P/L ratios to discriminate the cause of dyspnoea in patients admitted with an initial diagnosis of AHF-RI...

The association between type 2 diabetes mellitus (T2DM) and systemic inflammation may increase platelet reactivity and the accelerated development of vascular disease. Platelets are able to modulate the function of immune cells via the direct release of growth factors and pro-inflammatory chemokines through the production of microvesicles. The microvesicles trigger a transcellular delivery system of bioactive molecules to other cells acting as vectors in the exchange of biological information. Here, we consider the influence of platelets and platelet-derived microvesicles on cells of the immune system and the implications in the pathogenesis of T2DM...
