The patients' clinical history is neither a predictor for GIB bleeding nor a guide to the choice of the oral anticoagulant to be administered. Routinely applying bleeding risk screening, such as occult blood in the stool, should be added to the periodic laboratory checks for early recognition of patients at higher risk of GIB.

One of the fundamental problems is the evaluation of the preparedness of countries to cope with COVID-19 pandemic crisis to detect factors associated with the reduction of infectious disease and rollout of vaccinations in society. The study here confronts this problem by developing two basic indexes, which measure the performance to face pandemic threats by countries. In particular, the Index r (as resilience) detects which countries have had the best performance to reduce the negative impact of mortality related to COVID-19 pandemic and the Index p (as preparedness and prevention) assesses best-performer countries to support COVID-19 vaccinations to constrain future pandemic threats and support the recovery of socioeconomic systems. Index of resilience is a composite measure based on three indicators, given by average mortality, hospital occupancy and Intensive Care Units occupancy per 100 000 people, producing an overall score; Index of prevention is also a composite measure of two in
