Randomized Controlled Trial Multicenter Study Comparative Study
United States Military Cancer Institute Clinical Trials Group (USMCI GI-01) randomized controlled trial comparing targeted nodal assessment and ultrastaging with standard pathological evaluation for colon cancer.
Our randomized controlled trial previously demonstrated improved staging accuracy with targeted nodal assessment and ultrastaging (TNA-us) in colon cancer (CC). Our objective was to test the hypothesis that TNA-us improves disease-free survival (DFS) in CC. ⋯ TNA-us is associated with improved nodal diagnostic yield and enhanced staging accuracy (stage migration), which is further associated with improved DFS in early CC. This study is registered at clinicaltrials.gov under the registration number: NCT01623258.

Randomized Controlled Trial
Long-term propranolol use in severely burned pediatric patients: a randomized controlled study.
To determine the safety and efficacy of propranolol given for 1 year on cardiac function, resting energy expenditure, and body composition in a prospective, randomized, single-center, controlled study in pediatric patients with large burns. ⋯ Propranolol treatment for 12 months after thermal injury, ameliorates the hyperdynamic, hypermetabolic, hypercatabolic, and osteopenic responses in pediatric patients. This study is registered at clinicaltrials.gov: NCT00675714.

Comparative Study
Admission rapid thrombelastography can replace conventional coagulation tests in the emergency department: experience with 1974 consecutive trauma patients.
Injury and shock lead to alterations in conventional coagulation tests (CCTs). Recently, rapid thrombelastography (r-TEG) has become recognized as a comprehensive assessment of coagulation abnormalities. We have previously shown that admission r-TEG results are available faster than CCTs and predict pulmonary embolism. We hypothesized that r-TEGs more reliably predict blood component transfusion than CCTs. ⋯ The r-TEG data was clinically superior to results from 5 CCTs. In addition, r-TEG identified patients with an increased risk of early RBC, plasma and platelet transfusions, and fibrinolysis. Admission CCTs can be replaced with r-TEG.

Routine preoperative laboratory testing for ambulatory surgery is not recommended. ⋯ Preoperative testing is overused in patients undergoing low-risk, ambulatory surgery. Neither testing nor abnormal results were associated with postoperative outcomes. On the basis of high rates of testing in healthy patients, physician and/or facility preference and not only patient condition currently dictate use. Involvement from surgical societies is necessary to establish guidelines for preoperative testing.

To investigate the association between time from admission to appendectomy (TTA) and the incidence of perforation and infectious complications. ⋯ In this series, appendectomy delay did not increase the risk of perforation but was associated with a significantly increased risk of SSI in patients with nonperforated appendicitis. Prompt surgical intervention is warranted to avoid additional morbidity in this population.
