During the new pandemic caused by SARS-CoV-2, there is short knowledge regarding the management of different disease areas, such as coagulopathy and interpretation of D-dimer levels, its association with disseminated intravascular coagulation (DIC) and controversy about the benefit of anticoagulation. Thus, a systematic review has been performed to define the role of D-dimer in the disease, the prevalence of DIC and the usefulness of anticoagulant treatment in these patients. ⋯ Four recommendations were drawn based on expert opinion and scientific knowledge, according to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. The present review suggests the presence of higher levels of D-dimer in those with worse prognosis, there may be an overdiagnosis of DIC in the course of the disease and there is no evidence on the benefit of starting anticoagulant treatment based only on isolated laboratory data.

To evaluate changes in the epidemiology of mechanical ventilation in Spain from 1998 to 2016. ⋯ A significant decrease in mortality was observed in patients ventilated in Spanish ICUs. These changes in mortality could be related to modifications in ventilation strategy to minimize ventilator-induced lung injury.

To describe and compare the demographic characteristics and comorbidities of patients with COVID-19 who died in Spanish hospitals during the 2020 pandemic based on whether they were or were not admitted to an intensive care unit (ICU) prior to death. ⋯ The profile of COVID-19 patients who died without ICU admission is similar to that observed in the usual medical practice before the pandemic. The basal characteristics limiting their admission were age and global burden due to comorbidity, especially dementia and active cancer.

Secondary injury due to oxidation may occur during ischemic stroke, possibly leading to oxidative damage to deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Higher blood concentrations of 8-hydroxy-2'-deoxyguanosine (8-OHdG) (through the oxidation of guanosine from DNA) have been found in ischemic stroke patients than in healthy subjects, and in patients with versus without post-ischemic stroke depression. The present study was carried out to explore the possible association between serum DNA and RNA oxidative damage and mortality in patients with cerebral infarction. ⋯ The novel observation in this study is the association between global serum OGS concentration and mortality in ischemic stroke patients.
