Cardiomyopathies are a heterogeneous group of cardiac diseases for which diagnosis and treatment are not always simple. The diagnosis of cardiomyopathy, in particular the etiology, comes from an integration between symptoms and results collected by several instrumental exams. The brain storming for the diagnosis includes also the identification of the "red flags", i.e. the pathognomonic features for each etiology that can drive the choice of appropriate diagnostic tests and therapy. In this review, we provide a step by step approach in order to help cardiologists, not specifically dedicated to cardiomyopathies, to draw the diagnosis, therapy and follow-up. This approach will be accompanied by the consultation of other specialists to discuss together the results of the exams performed and to deepen extracardiac signs and symptoms.Myocarditis is a complex inflammatory disease of the myocardium, occurring secondary to viral infections or autoimmune mechanisms in most cases. Among its multiple clinical manifestations, arrhythmias are often underdiagnosed, in spite of their important prognostic value. In particular, ventricular arrhythmias complicating either active or previous myocarditis, are a significant cause of sudden cardiac death, especially in young people. Because of the absence of clinical trials specifically addressing this topic, nowadays updated international guidelines report extremely generic recommendations about optimal clinical management of patients with arrhythmic myocarditis. This review aims at both (i) showing the state of the art about patients with myocarditis and arrhythmias (ventricular arrhythmias in particular); and (ii) suggesting optimal diagnostic and therapeutic strategies for these patients, based on the experience of a high-volume referral center for arrhythmic myocarditis and ventricular arrhythmia management.Acute pulmonary embolism (PE) still represents the third leading cause of cardiovascular mortality in developed countries. In this regard, the last European guidelines offer important suggestions on the management of the disease in daily clinical practice but, at the same time, they do not take into account the feasibility of the recommendations according to the local available resources, including the presence or lack of adequate healthcare facilities (cardiological intensive care unit, cath-lab) or specialists (cardiologist available on a 24 h basis, interventional cardiologist, cardiac surgeon, etc.) all over the day. In the real clinical practice, those recommendations should be adapted to the local available resources. The aim of this document is to provide some suggestions regarding the diagnosis and treatment of acute PE, according to the possible available resources in different local circumstances.BACKGROUND Double balloon enteroscopy (DBE) is a diagnosis and therapy method for suspected small bowel bleeding (SSBB). The data for emergent DBE is limited in overt SSBB cases. The aim of this study was to investigate the role of diagnosis and therapy of emergent DBE in patients with overt SSBB. MATERIAL AND METHODS The clinical and endoscopic data for patients with overt SSBB undergoing DBE in a single center from January 2010 to December 2017 were collected and analyzed. Emergent DBE was defined as DBE performed less than 3 days of last bleeding onset. RESULTS A total of 265 DBEs in 265 patients with overt SSBB were enrolled (mean age, 44.7±17.3 years; 66.8% males). The patients were divided into 3 groups according to the timing of DBE less than 3 days (n=32), more than 3 days and less than 7 days (n=146), and more than 7 days (n=87) (first group was the emergent group, the latter 2 groups were the non-emergent groups). The diagnosis yield for the emergent group was significantly higher than the non-emergent groups (84.4% versus 65.1% or 59.8%, respectively, P7 days group 78.1%, 58.2% and 39.1%, respectively, P less then 0.05. The top 3 endoscopic treatments were hemostatic clips (21.9%), argon plasma coagulation (15.8%), and epinephrine injection (14.0%). CONCLUSIONS The emergent DBE had the highest yields for diagnosis and therapy. The study finding showed a pivotal role of emergent DBE in overt SSBB.The scattering of acoustic phonons by nonreciprocal spring defects inserted in an harmonic chain is investigated. The degree of nonreciprocity of the forces mediated by the defect springs is parameterized by a single quantity Δ that effectively takes into account the interaction of the coupled masses with hidden degrees of freedom of an underlying nonequilibrium system. We demonstrate a pronounced rectification effect with transmission having a preferential direction. Nonreciprocity also allows energy exchange between the system and the medium. Further, we show a cooperative action between defects mediated by resonant cavity modes. The influence of damping forces is also explored and shown to promote the rectification of the reflected vibrational wave component.Biocompatibility and neuron regenerating properties of various bioactive glass (BG)/Polyhydroxyalkanoate (PHA) blend composites were assessed in order to study their suitability for peripheral nerve tissue applications, specifically as lumen structures for nerve guidance conduits (NGCs). BG/PHA blend composites were fabricated using Bioactive glass® 45S5 (BG1) and BG 1393 (BG2) with the 2535 poly(3-hydroxyoctanoate/poly3-hydroxybutyrate), 2575 P(3HO)/P(3HB) blend (PHA blend). Various concentrations of each BG (0.5, 1.0 and 2.5 wt%) were used to determine the effect of BG on neuronal growth and differentiation, in single culture using NG108-15 neuronal cells and in a co-culture along with RN22 Schwann cells. NG108-15 cells exhibited good growth and differentiation on all the PHA blend composites showing that both BGs have good biocompatibility at 0.5, 1.0 and 2.5 wt% within the PHA blend. The Young's modulus values displayed by all the PHA blend/BG composites ranged from 385.6 MPa to 1792.6 MPa, which are able to provide the required support and protective effect for regeneration of peripheral nerves. selleck products More specifically, the tensile strength obtained in the PHA blend/BG1 (1.0 wt%) (10.0 ± 0.6 MPa) was found to be similar to that of rabbit peroneal nerve. This composite also exhibited the best biological performance in supporting growth and neuronal differentiation among all the substrates. The neurite extension on this composite was found to be remarkable with the neurites forming a complex connection network. Creative Commons Attribution license.
