Acute pulmonary embolism is a frequent cause of hospitalization and is associated with a wide range of symptom severity. Anticoagulants are the mainstay of treatment for acute pulmonary embolism; however, in patients with massive or submassive pulmonary embolism, advanced therapy with thrombolytics may be considered. ⋯ Alteplase is currently the thrombolytic agent most studied and with the most clinical experience for this indication, although the most appropriate dose remains controversial, especially in patients with low body weight. When considering thrombolysis, unfractionated heparin is the preferred initial anticoagulant due to its short duration of action and its reversibility should bleeding occur.

ReviewThe use of volume-assured pressure support noninvasive ventilation in acute and chronic respiratory failure: a practical guide and literature review.
Noninvasive positive pressure ventilation (NPPV) is an important tool in the management of acute and chronic respiratory failure. Traditionally, continuous positive airway pressure (CPAP) and bilevel positive airway pressure (BPAP) have been the most commonly utilized modes for these purposes. Newer hybrid modes of NPPV, such as average volume-assured pressure support (VAPS), combine the properties of both volume- and pressure-controlled NPPV and represent another tool in the treatment of acute and chronic respiratory failure. ⋯ The limited evidence available suggests that VAPS is equally effective in treating acute and chronic respiratory failure compared to BPAP. Overall, the evidence to suggest superiority of one mode over the other is lacking. There is a need for larger studies before firm conclusions can be made.

As a class, the target-specific oral anticoagulants (TSOACs) are at least as effective as warfarin, often with superior safety for the prevention of stroke in patients with nonvalvular atrial fibrillation (AF) and the treatment of acute venous thromboembolism (VTE) and prevention of recurrent VTE. Currently, dabigatran, the direct thrombin inhibitor, along with rivaroxaban and apixaban, direct factor Xa inhibitors, has been approved in multiple countries for these indications. ⋯ It is anticipated that the use of TSOACs will increase as practitioners and healthcare systems gain familiarity with these drugs and adopt their use into clinical practice. This review will provide a brief overview of the TSOAC Phase III clinical trials for prevention of stroke and systemic embolic events in patients with AF and the Phase III clinical trials for the prevention of recurrent VTE, discuss current treatment guidelines, address how TSOACs may help meet national safety goals, and provide clinical decision-making guidance regarding the use of TSOACs for hospitalists.

Venous thromboembolism (VTE) is a common complication in cancer patients. This review summarizes some of the most current knowledge of the epidemiology, risk factors, risk models, prophylaxis, and treatment of VTE in cancer patients. ⋯ Cancer-associated thrombosis is a common problem. As we begin to better understand the risk factors and biomarkers for cancer-associated VTE, we can further refine and develop risk-assessment models to determine those patients who would most likely benefit from anticoagulation. While LMWH products are generally preferred in cancer-related VTE, more research will continue to evolve our understanding of treatment and thrombopprophylaxis in cancer-associated VTE.

ReviewPerioperative anticoagulation and renal disease: an update.
As our surgical population becomes older and increasingly medically complex, knowledge of the most recent perioperative literature can provide guidance for physicians across multiple specialties caring for the surgical patient. Common issues many clinicians encounter in the perioperative period relate to anticoagulation and renal disease. This article identifies gaps in knowledge for the fields of perioperative anticoagulation, acute kidney injury, and chronic kidney disease and highlights recently published studies on these topics that attempt to fill these gaps and help clinicians provide excellent care for their patients.
