Subsequently, the dilator was successfully exchanged to an ERCP catheter that allowed for exchange to a 0.025-inch guidewire, except in one case where the catheter did not cross the fistula and a dilation balloon was inserted for an exchange to a 0.025-inch guidewire. The technical success rate of the EUS-BD was 100%. The adverse event rate was 19%. The application of the dedicated dilator for a 0.018-inch guidewire was considered feasible and safe for EUS-BD. The application of the dedicated dilator for a 0.018-inch guidewire was considered feasible and safe for EUS-BD.Nowadays, polyelectrolytes play an essential role in the development of new materials. Their use allows creating new properties of materials and surfaces and vary them in a wide range. Basically, modern methods are divided into three areas-the process of layer-by-layer deposition, free-standing films, and hydrogels based on polyelectrolytes. Layer-by-layer assembly of polyelectrolytes on various surfaces is a powerful technique. It allows giving surfaces new properties, for example, protect them from corrosion. Free-standing films are essential tools for the design of membranes and sensors. Hydrogels based on polyelectrolytes have recently shown their applicability in electrical and materials science. The creation of new materials and components with controlled properties can be achieved using polyelectrolytes. This review focuses on new technologies that have been developed with polyelectrolytes over the last five years. Global longitudinal strain (GLS) has become an alternative to left ventricular ejection fraction (LVEF) to determine systolic function of the heart. The absence of cut-off values is one of the limitations preventing full clinical implementation. The aim of this study is to determine a cut-off value of GLS for an increased risk of adver
