The gut microbiota is considered as our other "brain" and is implicated in several regulation of physiological metabolisms. The circulating level of TMAO, a metabolite of the gut microbiota, is directly correlated to the occurrence of cardiovascular events. ⋯ The disturbance in the metabolism and the composition of the gut microbiota is called "dysbiosis". Understanding the implication of the gut microbiota and developing new therapeutic strategies are promising research fields to manage metabolic and cardiovascular diseases.

Heroin use can be responsible for many respiratory complications including asthma. ⋯ Heroin use may be responsible for asthma onset, acute asthma exacerbations (which may require intubation and invasive ventilation) or deaths related to asthma. Heroin use must be sought in case of asthma exacerbation in young persons and practitioners must help heroin users to stop their consumption.

In order to determine the optimal duration of anticoagulation after an acute pulmonary embolism, the benefit risk balance needs to be analysed based on the risk of recurrent venous thromboembolism in the absence of anticoagulation and the risk of bleeding while on anticoagulant therapy. Such evaluation take in account the frequency and the severity of the risks; clinical variables appear more informative to predict recurrent venous thromboembolism than biochemical or morphological variables. ⋯ This last observation has two major implications: first, to identify, among patients with unprovoked pulmonary embolism, those who have a low risk of recurrence and who do not require indefinite anticoagulation; and second, in those who are eligible for indefinite anticoagulation, to reduce the risk of bleeding. If direct oral anticoagulant therapies are promising, however, additional clinical trials are needed to help physician for the daily practice.
