Heart failure is a major concern for public health systems, and several approaches of cellular therapy are being investigated with the goal of improving the function of these failing hearts. Many cell types have been used (skeletal myoblasts, hematopoietic, endothelial or mesenchymal progenitors, cardiac cells…), most often in the indication of post-ischemic heart failure rather than in the indication of genetic dilated cardiomyopathy. It is easier, indeed, to target a restricted area than the whole myocardium...

Inonotus obliquus polysaccharides (IOPs) are a potential drug for the prevention and treatment of cancer, cardiopathy, diabetes, AIDs, pancreatitis and other diseases. In this study, we found that IOP can act as a broad-spectrum antiviral drug against feline viruses in the in vitro experiment. Using cell models of feline calicivirus (FCV), we demonstrated that IOP treatment was capable of exhibiting anti-FCV strain F9 activity in cell-based assays and also showed low cytotoxicity. Investigation of the mechanism of action of the compound revealed that IOP treatment induces its inhibitory actions directly on virus particles through blocking viral binding/absorpting...

The first European Society of Cardiology (ESC) guidelines on atrial fibrillation (AF) developed in collaboration with the European Association for Cardio-Thoracic Surgery (EACTS) were published in August 2016. These guidelines replace the revised guidelines from 2012 and contain some interesting new aspects. The topics range from the pathophysiology through diagnostics, therapy and stroke prevention up to special clinical situations, such as atrial fibrillation in cardiopathy, sport and pregnancy. Early screening, patient informed consent, individualized therapy and the modification of factors promoting atrial fibrillation are of particular importance...

BACKGROUND: Weaning-induced pulmonary oedema (WiPO) is a well-recognised cause of failure of weaning from mechanical ventilation, but its incidence and risk factors have not been reliably described. We wanted to determine the incidence and risk factors in a population of critically ill patients. In addition, we wanted to describe the effects of diuretics when they are administered in this context. METHODS: We monitored 283 consecutive spontaneous breathing trials (SBT; T-piece trial) performed in 81 patients...

The scope of this article is to analyze the trajectory of Emmanuel Dias (1908-1962), a researcher at the Oswaldo Cruz Institute (OCI) and director of the Center for Studies and Prophylaxis of Chagas Disease (OCI outpost established in 1943 in the city of Bambuí, Minas Gerais), as a key actor in the acknowledgement of Chagas disease as a public health problem in Brazil and the Americas. It seeks to show that the conquest of this acknowledgement, the cornerstone of which was the staging of the first campaign to combat the disease in Brazil in 1950, was made possible by the intense political mobilization of Dias together with the various social groups, such as physicians, politicians and residents of rural areas, public health officials, governments and international organizations...

BACKGROUND: Cardiovascular disease is the leading cause of death in the Western world, and a major cause of this disease is atherosclerosis. Research has demonstrated that pregnancy-associated plasma protein A (PAPP-A) plays a role in cardiovascular disease, as evidenced by the association between PAPP-A and severity of heart damage. AIM: The aim of this work was to investigate the correlation between PAPP-A concentrations in coronary and peripheral blood and certain clinicopathological factors and antioxidant enzyme activities in patients diagnosed with coronary artery disease...

AIM: The L-type voltage-gated calcium channel Cav1.2 mediates the calcium influx into cells upon membrane depolarization. The list of cardiopathies associated to Cav1.2 dysfunctions highlights the importance of this channel in cardiac physiology. Calcium/calmodulin-dependent serine protein kinase (CASK), expressed in cardiac cells, has been identified as a regulator of Cav2.2 channels in neurons, but no experiments have been performed to investigate its role in Cav1.2 regulation. METHODS AND RESULTS: Full length or the distal C-terminal truncated of the pore-forming Cav1...

The incidence of severe complications of the Neisseria gonorrhoeae infection has presented variations over recent decades since the advent of penicillin. Gonococcal endocarditis (GE) still remains an ever-present threat afflicting the society's poor and sexually active young population. This entity frequently requires surgical intervention and usually exhibits a poor outcome. The interval between the onset of symptoms and the diagnosis does not usually exceed 4 weeks. One of the characteristics of GE is a proclivity for aortic valve involvement with large vegetation and valve ring abscess formation...

Acute respiratory failure (ARF) is a leading indication for performing critical care ultrasonography (CCUS) which, in these patients, combines critical care echocardiography (CCE) and chest ultrasonography. CCE is ideally suited to guide the diagnostic work-up in patients presenting with ARF since it allows the assessment of left ventricular filling pressure and pulmonary artery pressure, and the identification of a potential underlying cardiopathy. In addition, CCE precisely depicts the consequences of pulmonary vascular lesions on right ventricular function and helps in adjusting the ventilator settings in patients sustaining moderate-to-severe acute respiratory distress syndrome...

PURPOSE: Sudden cardiac death in young athlete is always tragic. Some international guidelines recommend the realization of an electrocardiogram before practicing competitive sports to carry out the risk of sudden cardiac death due to genetic cardiopathy like QT long syndrome. Unfortunately, the diagnosis can be difficult because intensive sport can increase the QT interval over normal recognized values for sedentary people. Using a QT correction formula free of heart rate appears essential...

Waardenburg syndrome is a rare autosomal dominant disease that may cause hearing loss, pigmentary abnormalities, neurocristopathy and partial albinism. Incidence is estimated as 2%-3% among the cases of congenital deafness and 1/42,000 of the general population. Children with Waardenburg syndrome usually require anaesthesia for the cochlear implant operation in early age. The features of the syndrome that may bear importance for anaesthetic management are laryngomalacia, multiple muscle contractures, limited neck movements, cyanotic cardiopathy and electrolyte imbalance...

Epoxygenase-dependent metabolites of arachidonc acid, EETs and the heme-oxygenase (HO)-1/carbon monoxide/bilverdin system share similarities in their activity and mediators. They control endothelial function, dilating small arterial vessels, decrease blood pressure, protect the heart from ischemic and hypertensive cardiopathy, control renal circulation and function, promote angiogenesis and organ regeneration, oppose oxidative stress and inflammation, improve diabetes and obesity, have protective effects on the liver, and participate in portal hypertension...

BACKGROUND AND AIMS: Postprocedural bleeding (PPB) is the most common adverse event associated with endoscopic resection. Several studies have tried to identify risk factors for PPB after gastric EMR and endoscopic submucosal dissection (ESD), with controversial results. This systematic review and meta-analysis aimed to identify significant risk factors for PPB after gastric EMR and ESD. METHODS: Three online databases were searched. Pooled odds ratio (OR) was computed for each risk factor using a random-effects model, and heterogeneity was assessed by Cochran's Q test and I(2)...

OBJECTIVES: Improvement of clinical results in heart transplantation (HTx) has favoured the expansion of indication criteria towards aged population. The impact of increasing recipient age is controversial and, owing to donor shortage, the debate still remains whether HTx is justified for older patients. We analysed age as a prognostic factor at long-term after HTx and if it should be a determinant in organ allocation. METHODS: Data of 364 consecutive patients who underwent cardiac transplantation between 1999 and 2014 at the University Hospital of Udine were analysed...
