Importance  Delta hemoglobin (ΔHb), defined as the difference between the preoperative hemoglobin (Hb) level and the nadir Hb level during a patient’s hospitalization, may be associated with adverse outcomes even if the absolute level of Hb remains greater than the transfusion threshold of 7 g/dL.

Invited Commentary: Determining When Patients Need Transfusions; Samuel A. Tisherman, MD
Invited Commentary 
Samuel A. Tisherman, MD

Blood transfusions save lives but carry risks, including immunosuppression, infections, and transfusion reactions. For stable patients, a restrictive transfusion strategy (transfusions for a hemoglobin [Hb] level of <7 g/dL [to convert to grams per liter, multiply by 10.0]) is safe, possibly beneficial, and saves money.13...

Invited Commentary 
Martin A. Schreiber, MD

Dawes and colleagues1 have evaluated the relationship between compliance with the Brain Trauma Foundation guidelines and outcomes in patients with traumatic brain injury (TBI) in a consortium of 14 hospitals in Los Angeles County. They found wide variance in compliance within the consortium and no association between ...

Invited Commentary 
Jason T. Lee, MD

The increasing reliance on and relative availability of high-quality cross-sectional imaging of vascular structures has altered the workup of patients with blunt trauma. Traditional 2-dimensional angiography and the extensive resources necessary to perform these procedures in critically injured patients have largely been replaced by rapid computed tomography angiography ...

Invited Commentary 
Linwah Yip, MD; Sally E. Carty, MD

Incidentally identified adrenal nodules are seen bilaterally in as many as 17% of patients as reported in Pasternak et al.1 The management of patients with bilateral incidentalomas presents a clinical challenge and is optimized with a multidisciplinary and experienced approach that is highlighted beautifully in this high-volume ...

To the Editor We read with great interest the study by Tevis et al1 describing the development of a nomogram to predict the 30-day risk of readmission for patients following hospital discharge after general surgery. However, deficiencies in the methods and in the reporting limit the usefulness ...
