We assessed whether bariatric surgery before pregnancy lowers the risk of severe maternal morbidity to a level comparable to no obesity. ⋯ Pregnant women with prior bariatric surgery have similar risks as nonobese women for most types of severe maternal morbidity, except for intensive care unit admission.

Observational Study
Pre-transplant T-cell Clonality: An Observational Study of a Biomarker for Prediction of Sepsis in Liver Transplant Recipients.
This study investigated the ability of pre-transplant T-cell clonality to predict sepsis after liver transplant (LT). ⋯ T-cell repertoire clonality is a novel biomarker predictor of sepsis before development of clinical symptoms. Early sepsis monitoring and management may reduce post-LT mortality. These findings have implications for developing sepsis-prevention protocols in transplantation and potentially other populations.

We examine how esophagectomy volume thresholds reflect outcomes relative to patient characteristics. ⋯ Current Leapfrog Group esophagectomy volume guidelines may not predict optimal outcomes for all patients, especially at extremes of age and comorbidities.

Observational Study
Effectiveness of Preoperative Iron Supplementation in Major Surgical Patients with Iron Deficiency: A Prospective Observational Study.
To evaluate the effectiveness of routine intravenous iron in surgical patients with iron deficiency anemia (IDA). ⋯ Preoperative IDA management with intravenous iron is effective in improving hemoglobin level, thereby reducing intraoperative RBC transfusion rate particular if iron is administrated >7 days before surgery. Hospital length of stay was reduced in all preoperatively iron-supplemented IDA patients.

A courtesy author is an individual who has not met authorship criteria but is listed as an author. This practice is common and often seen as victimless. Because publications are used for funding and promotion decisions, it is critical to understand biases in this practice. ⋯ Courtesy authors were more often male, older, and higher rank than first/senior authors. Fear of career consequences was a major motivator for including courtesy authors. Understanding the motivations and pressures leading to courtesy authorship will help to correct this practice.
