[Not Available].

Being able to critically evaluate modern cohort studies is important when being presented with claims based on observational evidence. In this review article, key aspects of the cohort design are presented using an example of a cohort study investigating the association between the use of SGLT2 inhibitors and gout. We describe the active comparator, new user design, modern methods used to address confounding, how to identify the most common sources of bias, and how to interpret study results appropriately.

[Thromboembolic complication following temporary discontinuance of anticoagulant therapy in a patient with mechanical heart valve].

Patients with mechanical heart valves are treated with oral anticoagulant therapy in order to minimize the risk of thromboembolism. During invasive procedures it is recommended to temporarily discontinue the oral anticoagulant therapy and substitute with injections of low-molecular-weight heparin. We describe a case where a patient discontinued the oral anticoagulant therapy and had no substitution with low-molecular-weight heparin.

[Optimal interval screening and observation of abdominal aortic aneurysms].
