Pulmonary Embolism News and Research

RSS

A pulmonary embolism is a sudden blockage in a lung artery. The cause is usually a blood clot in the leg called a deep vein thrombosis that breaks loose and travels through the bloodstream to the lung.

May-Thurner anatomy common in patients with CTEPH, new study shows

Like highways, roads, and side streets, blood vessels in the human body come in different sizes, with a range of traffic-carrying capacities. These differences are critical to facilitating blood flow through tissues.

Signs and risk factors of pulmonary embolism missed in dementia patients

Patients with dementia who had signs and risk factors of a pulmonary embolism, or a blood clot in the lungs, were much less likely to be tested for pulmonary embolism than patients without dementia who had the same signs and risk factors.

Researchers find no serious health effects linked to mRNA COVID-19 vaccines

Federal and Kaiser Permanente researchers combing the health records of 6.2 million patients found no serious health effects that could be linked to the 2 mRNA COVID-19 vaccines.

Large Israeli study offers detailed look at safety profile of mRNA vaccine against SARS-CoV-2

A deep look into a nationwide mass vaccination setting in Israel revealed that the BNT162b2 (Pfizer–BioNTech) vaccine is not linked with an elevated risk of a majority of the adverse events under study, with the exception of myocarditis. However, even that potentially severe adverse event is much more pervasive following the infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), found a new study published in the New England Journal of Medicine (NEJM).

Assessing the risks of thrombotic events post vaccination with ChAdOx1 and BNT162b2 vaccines in England

Researchers aim to better understand the population-level thrombotic risks post COVID-19 vaccination with both the ChAdOx1-S and BNT162b2 vaccines.

Study examines safety of COVID-19 vaccine in a nationwide mass-vaccination setting

The Clalit Research Institute, in collaboration with researchers from Harvard University, analyzed one of the world's largest integrated health record databases to examine the safety of the Pfizer/BioNTech BNT162B2 vaccine against COVID-19.

Availability heuristic plays a role in how physicians make complex testing decisions

Emergency department physicians who saw patients with a pulmonary embolism-;a blood clot in the lung-;were about 15% likelier over the next 10 days to test subsequent patients for the same thing.

Angiotensin II type 1 receptor-targeting autoantibodies may increase COVID-19 severity

A team of US-based scientists recently demonstrated that pro-thrombotic autoantibodies that target angiotensin II type 1 receptor (AT1R) may be associated with endothelial complications observed in coronavirus disease 2019 (COVID-19), a novel disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Findings suggest that the cross-linking of fibrin proteins is key to reducing blood clot formation

Researchers have found that the y cross-chain structure of fibrin proteins is essential to stabilizing blood clots that can lead to harmful embolism formation.

A new guide for cancer-associated thrombosis

Ever since the association between cancer and thrombosis was reported by Jean-Baptiste Bouillaud in the early 19th century, cancer-associated thrombosis has remained a challenging domain of cancer management.

Three cases of stroke reported in young adults following covid-19 vaccination

Clots in the arteries (arterial thrombosis) are the most common cause of stroke (ischemic stroke) and have been reported in detail for the first time in young adults who received the Oxford–AstraZeneca covid-19 vaccine in a letter from UK stroke specialists published online in Journal of Neurology Neurosurgery & Psychiatry.

Little evidence for mRNA COVID-19 vaccine-associated thrombocytopenia, suggests new FDA study

Even as a host of vaccines have been rolled out to counter the coronavirus disease 2019 (COVID-19) pandemic, some serious adverse effects have been reported, in the form of thrombocytopenia. A new study in the journal Vaccine reports the results of an evaluation of reported cases of this condition, using data from the Vaccine Adverse Event Reporting System (VAERS).
