D-Dimer to Rule Out Venous Thromboembolism During Pregnancy: A Systematic Review and Meta-Analysis
Pregnant women have a higher risk of venous thromboembolism (VTE) and an increasing D-Dimer over the course of pregnancy. The majority of clinical guidelines recommend the D-dimer should not be used to assess the risk of VTE in pregnant women.

Performance of Novel High-Sensitivity Cardiac Troponin I Assays for 0/1-Hour and 0/2- to 3-Hour Evaluations for Acute Myocardial Infarction: Results From the HIGH-US Study
A strategy of high-sensitivity cardiac troponins over short time intervals for the diagnosis of acute myocardial infarction has been recommended in European cardiology guidelines. It is unclear if the European strategy is generalizable to the US population.

Pulmonary Complications of Opioid Overdose Treated with Naloxone
Pulmonary complications after opioid overdose include: non-cardiogenic pulmonary edema, aspiration pneumonia/pneumonitis and acute respiratory distress syndrome. Multiple mechanisms have been proposed for these complications. These complications have been described in opioid overdose both with and without Naloxone administration.

Effects of Tranexamic Acid on Death, Disability, Vascular Occlusive Events and Other Morbidities in Patients with Acute Traumatic Brain Injury (CRASH-3): A Randomised, Placebo-Controlled Trial
Head trauma is a leading cause of trauma related morbidity and mortality worldwide. Tranexamic acid (TXA) inhibits fibrinolysis and can decrease ongoing hemorrhage. In the CRASH-2 Trial, TXA given within 3 hours of injury was shown to decrease mortality from major extracranial injury (CRASH 2 Investigators,

Cervical Spine Injury Risk Factors in Children with Blunt Trauma
Pediatric cervical spine injuries (CSI) are rare (1-2%) after blunt trauma. Decision rules to identify adults at low risk of cervical spine injury have been developed (NEXUS criteria (Hoffman, NEJM 2000,

Apneic Oxygenation Reduces Hypoxemia During Endotracheal Intubation in the Pediatric Emergency Department
Oxygenation is particularly important in children undergoing endotracheal intubation. They have higher oxygen consumption than adults and become hypoxemic more quickly with rapid sequence intubation. Apneic oxygenation (AO) is the process of providing a high flow rate of oxygen through a standard nasal cannula prior to endotracheal intubation (ETI) without bag-valve mask ventilation.
