Community-Onset Venous Thromboembolism in Children: Pediatric Emergency Medicine Perspectives.

Semin Thromb Hemost 2021 May 10. Epub 2021 May 10.

Division of Hematology, Department of Pediatrics, Johns Hopkins University School of Medicine, Baltimore, Maryland.

Pediatric venous thromboembolism (VTE) is a condition increasingly encountered by emergency medicine physicians. Unfortunately, despite increased incidence, the diagnosis of pediatric VTE relies on a high index of suspicion from clinicians. Delays in diagnosis and initiation of treatment can lead to poor outcomes in children, including an increased risk of mortality from pulmonary embolism, increased risk of VTE recurrence, and the development of the post-thrombotic syndrome.

Efficacy and Safety of Non-Vitamin K Antagonist Oral Anticoagulants in Pediatric Venous Thromboembolism Treatment and Thromboprophylaxis: A Systematic Review of the Literature.

Semin Thromb Hemost 2021 May 10. Epub 2021 May 10.

Johns Hopkins All Children's Institute for Clinical and Translational Research, St. Petersburg, Florida.

Venous thromboembolism (VTE) in children can lead to significant morbidity and mortality. Traditionally, treatment for thrombotic events in pediatric patients has been limited mainly to unfractionated heparin, low-molecular-weight heparin (LMWH), or vitamin K antagonists. Since the first non-vitamin K antagonist oral anticoagulant (NOAC) was approved for adult use, these agents have gained popularity for a variety of indications. Read More

Work-life conflict and cardiovascular health: 5-year follow-up of the Gutenberg Health Study.

PLoS One 2021 7;16(5):e0251260. Epub 2021 May 7.

Institute and Policlinic of Occupational and Social Medicine (IPAS), Faculty of Medicine Carl Gustav Carus, TU Dresden, Germany.

Introduction: Work-life conflicts (WLC) may impact health, but few studies prospectively consider the impact of WLC on objective outcomes such as cardiovascular disease. Using data from the Gutenberg Health Study (GHS), we examined if WLC at baseline was associated with an increased five-year incidence of cardiovascular events (myocardial infarct, stroke, atrial fibrillation, peripheral artery disease, coronary artery disease, chronic heart failure, sudden cardiac death). We also considered if WLC was associated with incident hypertension and arterial stiffness and if the effects of WLC on cardiovascular health differ for men and women. Read More

Interplay between inflammation and thrombosis in cardiovascular pathology.

Nat Rev Cardiol 2021 May 6. Epub 2021 May 6.

Medizinische Klinik und Poliklinik I, University Hospital, LMU Munich, Munich, Germany.

Thrombosis is the most feared complication of cardiovascular diseases and a main cause of death worldwide, making it a major health-care challenge. Platelets and the coagulation cascade are effectively targeted by antithrombotic approaches, which carry an inherent risk of bleeding. Moreover, antithrombotics cannot completely prevent thrombotic events, implicating a therapeutic gap due to a third, not yet adequately addressed mechanism, namely inflammation. Read More
