The clinical characteristics and mutation search within monogenic diabetes genes in type 1 diabetes patients with long-term disease and preserved kidney function.
Some patients with type 1 diabetes (T1DM) are free from advanced complications despite long‑standing disease. These patients may be carriers of gene mutations responsible for maturity‑onset diabetes of the young and may have been misdiagnosed with T1DM. ⋯ Patients with long‑term T1DM and preserved kidney function have good glycemic control, elevated HDL cholesterol levels, low insulin requirements, near ‑normal BMI, and a rare occurrence of mutations in monogenic diabetes genes.

ReviewStatins in prevention of thromboembolic events: from seminal studies to recent advances.
Statins, 3‑hydroxy‑methylglutaryl coenzyme A reductase inhibitors, reduce the rate of cardiovascular events in primary and secondary prevention, and represent a cornerstone in the management of atherosclerotic vascular disease. Statins were also shown to be effective in lowering the risk of venous thromboembolism (VTE) in its primary and secondary prevention, but their use in VTE prophylaxis is still not approved and recommended in current guidelines. Several antithrombotic mechanisms of these cholesterol‑lowering agents, largely independent of the magnitude of low‑ density lipoprotein cholesterol reduction, were demonstrated in a broad spectrum of experimental in vitro and in vivo models. ⋯ Anticoagulant properties of statins, reported for the first time 25 years ago, involve downregulation of tissue factor expression with a subsequent decreased thrombin generation and inhibition of thrombin‑mediated reactions, including factor V and factor XIII activation, and enhanced endothelial thrombomodulin expression resulting in increased protein C activation. Enhanced fibrinolysis was also reported partly as a result of reduced activity of fibrinolysis inhibitors such as plasminogen activator inhibitor‑1 (PAI‑1) and thrombin‑activatable fibrinolysis inhibitor. This review summarizes the findings of the studies from the 1990s until the most recent reports to update our knowledge on the impact of statins on blood coagulation and its potential clinical relevance.

Multicenter StudyTranscatheter aortic valve-in-valve implantation for failed surgical bioprostheses: results from Polish Transcatheter Aortic Valve-in-Valve Implantation (ViV-TAVI) Registry.
Transcatheter aortic valve‑in ‑valve implantation (ViV‑TAVI) has emerged as an alternative to redo surgery in patients with failed surgical aortic bioprosthesis. ⋯ Transcatheter treatment of failed bioprostheses is increasingly common, with the best hemodynamic effect shown for supra ‑annular valves. The introduction of second‑generation valves has improved procedural and clinical outcomes.

ReviewAspirin‑induced asthma: a still evolving area of basic and clinical research.
The first modern description of respiratory syndrome of aspirin hypersensitivity was published over half of the century ago, but the pathogenesis of the disease is still elusive. Just a few years after discovery how aspirin works, Andrew Szczeklik and his co‑workers described that asthmatics with aspirin hypersensitivity cross‑react to the whole class of nonsteroidal anti‑inflammatory drugs. It took rest of his life to seek for an answer on how this disease, nowadays referred to as N ‑ERD, develops and how it can be treated. ⋯ Involvement of blood platelets and recently described mucosal basophils are areas of ongoing studies in the disease. Aspirin hypersensitivity is an acquired condition; therefore, the search for genetic predisposition using classic association studies was inconclusive. There is a new hope to explain mechanisms of aspirin hypersensitivity by studies of innate lymphoid cells, which have a central role in the regulation of respiratory mucosa function in asthma.

Diagnostic and therapeutic management in gastroesophageal reflux disease: consensus of the Polish Society of Gastroenterology.
The paper was prepared by an expert group appointed by the Polish Society of Gastroenterology with an aim to update and systematize the knowledge about diagnosis and treatment of gastroesophageal reflux disease (GERD). Based on the previously published guidelines of international societies, expert consensuses, and recently published good quality data, we formulated 74 statements regarding the definition, diagnosis and treatment of GERD and assessed the level of acceptance of these statements and the reliability of the data. ⋯ In addition, we discussed the indications for surgical treatment as well as the situations in which surgical treatment is not indicated with emphasis on the importance of preoperative diagnostics. The role of add-on therapy and indications for maintenance treatment are defined.
