The European Eosinophilic Granulomatosis with Polyangiitis (EGPA) study group first gathered in Firenze in December 2018. The discussion was centred around the clinical and therapeutic needs in EGPA which still remain unmet. Indeed, EGPA is a puzzling and rare disease which shares clinical features with other anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAVs) and hypereosinophilic syndromes (HESs). ⋯ Thus, the aim of the meeting was to stimulate ongoing research, to promote collaborative European studies and to define the main issues on which future studies should be focused. Current fields of research on EGPA include potential serological biomarkers of disease activity and of specific organ involvement, possible links between different genetic variants and clinical phenotypes, and new therapeutic perspectives. Herein, we give an overview of the meeting with the goal to stimulate an international collaboration and new points of discussion.

Aspirin, in 2017, has celebrated its 120th birthday. The efficacy and safety of low-dose aspirin in secondary prevention of cardiovascular disease is well supported by many studies, instead in primary prevention it remains controversial, especially in the aftermath of the publication in 2018 of three novel primary prevention randomized clinical trials, showing that the benefit of low-dose aspirin, although additive to that of statin, is counterbalanced by an excess of (mainly gastrointestinal) bleeding events. The signal for a net benefit seems to be even more controversial in the elderly starting aspirin after the age of 70 years. ⋯ This is a particularly complex task, given the different immediate and long-term impact of diverse outcomes on health, the dynamic nature over time of the benefit/risk balance, prompting periodic re-assessments of its indication, and the interindividual variability in aspirin response. The chemopreventive properties of aspirin, anticipated by a large body of epidemiological and mechanistic evidence, are awaiting their final confirmation by the long-term follow-up of the latest trials specifically designed to assess this endpoint, with the expectation to subvert the delicate benefit/risk balance of aspirin in primary prevention. This review is intended to provide an interpretation of past and current evidence to guide clinical decision making on the contemporary patient.

The human respiratory tract, usually considered sterile, is currently being investigated for human-associated microbial communities. According to Dickson's conceptual model, the lung microbiota (LMt) is a dynamic ecosystem, whose composition, in healthy lungs, is likely to reflect microbial migration, reproduction, and elimination. However, which microbial genera constitutes a "healthy microbiome" per se remains hotly debated. ⋯ Some authors hypothesize that the use of specific bacterial strains, termed "probiotics," with positive effects on the host immunity and/or against pathogens, could have beneficial effects in the treatment of intestinal disorders and pulmonary diseases. In this manuscript, we have reviewed the literature available on the LMt to delineate and discuss the potential relationship between composition alterations of LMt and lung diseases. Finally, we have reported some meaningful clinical studies that used integrated probiotics' treatments to contrast some lung-correlated disorders.

Oral anticoagulants (OA) are effective drugs for treating and preventing the formation of blood clots in patients with atrial fibrillation, mechanical heart valves and venous thromboembolism but their therapeutic effect is always counterbalanced by an increased risk of bleeding. Direct oral anticoagulants (DOACs) have brought advantages in the management of many patients, with evidence of a lower risk of intracranial bleeding in comparison to vitamin K antagonists (VKAs). However, due to the increased number of anticoagulated patients worldwide, major and life threatening OA-related bleeding is also increasing, and effective reversal strategies are needed. ⋯ There is an urgent need for well-designed studies in this field. In the meanwhile, to improve the correct use of available resources and patients' outcomes, we suggest a seven-element bundle for an optimal management of OA-associated major bleeding, including the implementation of fast turnaround time for laboratory tests in emergency, i.e. INR and DOAC plasma levels, and to build up a 'bleeding team' that includes experts of hemostasis, lab, trauma, emergency medicine, endoscopy, radiology, and surgery in every hospital.
