Venous thromboembolism is a preventable medical condition associated with significant morbidity and mortality. It can lead to deep vein thrombosis, pulmonary embolism, and stroke. Thrombi develop when intravascular conditions promote activation of the coagulation system or when there is an imbalance between endogenous anticoagulants and procoagulants. ⋯ Historically, anticoagulants were limited to heparins and vitamin K antagonists. Over the past 15 years, however, several new anticoagulant medications have been introduced. This article describes commonly prescribed and newer anticoagulants available to health care professionals, including their mechanism of action, therapeutic use, unique characteristics, and available reversal agents in the event of life-threatening bleeding.

Evaluating, diagnosing, and managing patients with consumptive thrombocytopenia is challenging because of the overlapping nature of many of the diseases that reduce platelet counts. Immune thrombocytopenia (and its variations), drug-induced immune thrombocytopenia, and heparin-induced thrombocytopenia result from autoimmune antibody-mediated destruction of platelets. ⋯ Platelet-associated coagulopathies are infrequently encountered by most providers, and limited exposure to these types of patients, combined with the wide variety of treatment options for reversing bleeding or thrombotic sequelae, makes management difficult. This article reviews the pathophysiology, patient presentation, diagnostic testing, and specific management strategies and challenges of these thrombocytopenias.

A new paradigm for disease diagnosis and treatment is emerging that will bring about changes in health care delivery in and out of the hospital setting. Over the past several decades, genomic medicine has been one of the fastest growing fields in acute and chronic health care. ⋯ This article reviews the current state of genetic and genomics science and looks at the expanding field of genomic medicine's integration into precision medicine. The aim of this article is to raise awareness and spark further inquiry to the remarkable field of genomics and precision medicine.

Extracorporeal membrane oxygenation is a rapidly emerging treatment for respiratory or cardiac failure and is used as a bridge to recovery, transplant, or destination therapy. Adult patients receiving extracorporeal membrane oxygenation also receive significant amounts of pharmacotherapy. ⋯ Understanding pharmacokinetics in adult patients receiving extracorporeal membrane oxygenation is important to correctly select and dose medications in this patient population. This article reviews published studies of the effects of extracorporeal membrane oxygenation on pharmacokinetics in adults.
