Prominent coagulation disorder is closely related to inflammatory response and could be as a prognostic indicator for ICU patients with COVID-19.
The new outbreak of Coronavirus Disease 2019 (COVID-19) has emerged as a serious global public health concern. A more in-depth study of blood coagulation abnormality is needed. We retrospectively analyzed 147 consecutive patients with COVID-19 who were admitted to three ICUs in Wuhan from February 9th, 2020 to March 20th, 2020. ⋯ The high levels of PT, FDP and DD were correlated with in-hospital mortality (p < 0.001). In conclusion, blood coagulation disorder was prominent in ICU patients with COVID-19 and was correlated with multi-inflammation factors. The abnormality of blood coagulation parameters could be an adverse prognostic indicator for ICU patients with COVID-19.

Clopidogrel increases risk of pneumonia compared with aspirin in acute ischemic minor stroke patients.
Antiplatelet agents may increase the risk of infections via suppressing platelet-mediated immune response. Here we assessed the contribution of clopidogrel versus aspirin to the development of pneumonia during an acute ischemic stroke admission. A retrospective cohort study was conducted of acute ischemic stroke patients who were admitted to our hospital from 2015 to 2018. ⋯ However, we found that clopidogrel was associated with increased risk of pneumonia compared with aspirin in minor stroke patients (adjusted odds ratio, 2.21; 95% CI 1.12-4.34; P = 0.021), and a statistically insignificant increase of pneumonia in diabetics (adjusted odds ratio, 1.94; 95% CI 0.96-3.94; P = 0.065). Compared with aspirin, clopidogrel is associated with increased pneumonia in minor stroke patients among who the interference of stroke-induced immunosuppression is minimized. Hence, aspirin may be a better choice for minor stroke patients in acute phase of ischemic stroke when pneumonia most frequently occurs.

Incidence and consequences of systemic arterial thrombotic events in COVID-19 patients.
A high incidence of thrombotic events, particularly deep vein thrombosis and pulmonary embolism, has been clearly documented in COVID-19 patients. In addition, small series of patients with coronary, cerebrovascular and peripheral arterial thrombotic events have also been reported, but their true incidence and consequences are not well described, and constitute the objective of this study. From February 1st to April 21st, 2020, 2115 COVID-19 patients were treated at Hospital Universitario Fundación Alcorcón (Madrid, Spain), and 1419 were eventually admitted. ⋯ All three cases developed necrosis of the toes, two of them with bilateral involvement. The hospitalization death rate of patients with an arterial event was 28.6%. Although COVID-19 may favor the occurrence of thrombotic events, the destabilization and thrombosis of arterial atherosclerotic plaques do not seem to be a frequent mechanism which warrants the need for specific systematic preventive measures.

Case ReportsOvarian vein thrombosis after coronavirus disease (COVID-19) infection in a pregnant woman: case report.
Corona virus outbreak started in December 2019, and the disease has been defined by the World Health Organization as a public health emergency. Coronavirus is a source of deep venous thrombosis (DVT) due to complications such as over-coagulation, blood stasis, and endothelial damage. In this study, we report a 26-year-old pregnant woman with coronavirus who was hospitalized with a right ovarian vein thrombosis at Besat Hospital in Sanandaj. Risk classification for deep vein thrombosis (DVT) disease is of crucial importance for the forecast of coronavirus.
