Impact of atrial fibrillation and anticoagulation on the risk of death, thromboembolic disease and bleeding in patients with COVID-19: the ACO-VID Registry.

Objective: To describe the clinical profile, risk of complications and impact of anticoagulation in COVID-19 hospitalized patients, according to the presence of atrial fibrillation (AF).

Methods: Multicenter, retrospective, and observational study that consecutively included patients >55 years admitted with COVID-19 from March to October 2020. In AF patients, anticoagulation was chosen based on clinicians' judgment.

Study of the frequency and reasons for discontinuation of different lines of treatment in patients with multiple myeloma.

The availability of new agents for the treatment of multiple myeloma has allowed the use of multiple lines of treatment, but a percentage of patients do not reach to receive this combination because of toxicity and early death. In this regard, a cross-sectional European study evaluated the management of different lines and discontinuation of treatment in 7635 patients from seven countries in routine clinical practice, finding that 39% of European patients do not receive a second line and that only 4% of patients reach third line in Spain, a figure that is striking when comparing with the rest of the countries. We analyze the frequency and causes of treatment discontinuation in a series of 108 patients from a Spanish University hospital showing that the main reason for permanent treatment discontinuation after finishing first line was to have a response, while death due to disease progression accounted for the main reason in subsequent lines of therapy, with its frequency increasing according to the number of lines received.
