Kim et al design a predictive model for adverse outcomes in older surgical patients. See also the invited commentary by Zenilman.
Hicks and coauthors examine whether disparities in trauma survival for blacks vs whites persist in patients 65 years or older.
Scales et al compare the effectiveness of shock wave lithotripsy and ureteroscopy to fragment or remove urinary stones in a large private payer cohort. Among beneficiaries who had an emergency department visit for a kidney stone, they estimate the probability of repeat intervention following an initial procedure. See the Invited Commentary by Gore.
Li and coauthors investigate whether pressure distension during vein graft preparation leads to endothelial injury and intimal thickening.
Fallon et al determine the probability of wean from parenteral nutrition (PN) in neonates with short bowel syndrome (SBS) based on small intestinal length amidst the new era of hepatoprotective strategies and multidisciplinary management.
Gadzinski et al evaluate discharge practice patterns and use of post–acute care after surgical admissions at critical access hospitals. See the invited commentary by Resnick and Barocas.
Mihaljevic et al investigate conditions under which benefits of robotic surgery mitigate high technology costs. See also the invited commentary by Yuh.
Fonseca et al determine whether MR imaging in pregnant patients with suspected appendicitis improves outcomes, minimizes LOS, and lowers hospital charges. They performed a retrospective review at a university tertiary referral center of pregnant patients seen during an 11-year period and followed up through delivery.
Brown and coauthors evaluate the effect of hospital length of stay and postoperative complications on total charges in patients undergoing elective pancreaticoduodenectomy.
Riccardo et al investigated the distribution of the number of excised lymph nodes in a large patient series to identify values that may serve as benchmarks for monitoring the quality of lymphadenectomy in patients with melanoma.
Courcoulas et al determine feasibility of a randomized clinical trial and compare initial outcomes of bariatric surgery and a structured weight loss program for treating type 2 diabetes mellitus.
Halperin et al test the feasibility of methods to conduct a larger multisite trial to determine the long-term effect of Roux-en-Y gastric bypass surgery compared with an intensive diabetes medical and weight management program for type 2 diabetes in obese patients.
Salottolo et al investigate the effect of age on the association between the Glasgow Coma Scale score and anatomic severity of traumatic brain injury (TBI). See the invited commentary by Yeh.
Kitano and colleagues describe 2 cases of melanoma of the appendix presenting with appendicitis and review their institutional experience with this entity.
