Quraishi and colleagues conducted a retrospective analysis investigating the association between preoperative 25-hydroxyvitamin D (25[OH]D) status and the risk for hospital-acquired infections (HAIs).
Gonzalez et al determine whether increased mortality at low-volume hospitals performing cardiovascular surgery is a function of higher postoperative complication rates or of less successful rescue from complications. Kao provides commentary in an invited critique.
Bagaria et al use as an example the triple-negative phenotype defined by the absence of estrogen
receptor, progesterone receptor, and human epidermal growth factor 2 to examine whether such
inclusion improves the prognostic accuracy of TNM staging for breast cancer.
Halabi et al examine the use of epidural analgesia in laparoscopic colorectal surgery at the
national level and compare its outcomes with those of conventional analgesia.
Glance and colleagues aimed to determine whether providing hospitals with benchmarking information on their risk-adjusted trauma mortality outcomes would decrease mortality in trauma patients. Dimick and Hendren provided an invited Article .
Kadera and colleagues aimed to perform a detailed survival analysis of their institution’s experience with patients with locally advanced/borderline resectable pancreatic ductal adenocarcinoma who were downstaged and underwent surgical resection and (2) identify prognostic biomarkers that may help guide a decision for the use of adjuvant therapy in this patient subgroup. L. Andrew DiFronzo, MD, provided an invited Article .
Jafari and colleagues aimed to determine the associated 30-day morbidity and mortality of cytoreductive surgery–hyperthermic intraperitoneal chemotherapy (HIPEC) in the treatment of metastatic and primary peritoneal cancer in American College of Surgeons National Surgical Quality Improvement Program centers. Arrington and Kim provided a related invited Article .
Juo and colleagues used the US Nationwide Inpatient Sample database to examine the outcomes and costs of open, laparoscopic, and robotic colectomies before and after propensity score matching across the 3 surgical approaches. James Yoo, MD, provided an invited Article .
Yen et al evaluate measures of surgical expertise, including the percentage of a surgeon’s operations for breast cancer, on the use of sentinel lymph node biopsy for invasive breast cancer. Zenilman provides an invited commentary.
Haut et al examine the comparative effectiveness of prophylactic inferior vena cava filters in trauma patients using meta-analysis to determine whether the filters prevented pulmonary embolism (PE), fatal PE, and mortality.
Neychev and Salinger elucidate the mechanics of needle-pancreas interaction and make adjustments to their pancreaticojejunostomy technique with the purpose of minimizing shear and compressive stress.
Orloff evaluates the findings of 2 randomized clinical trials that compared the use of (1) emergency portacaval shunt (EPCS) and emergency endoscopic sclerotherapy and (2) EPCS and transjugular intrahepatic portal-systemic shunt in patients with bleeding esophageal varices.
