Multicenter Study
Risk of perforation increases with delay in recognition and surgery for acute appendicitis.
Appendicitis remains a common indication for urgent surgical intervention in the United States, and early appendectomy has long been advocated to mitigate the risk of appendiceal perforation. To better quantify the risk of perforation associated with delayed operative timing, this study examines the impact of length of inpatient stay preceding surgery on rates of perforated appendicitis in both adults and children. ⋯ Greater inpatient delay before appendectomy is associated with increased perforation rates for children and adults within this population-based study. These findings align with previous studies and with the conventional progressive pathophysiologic appendicitis model. Randomized prospective studies are needed to determine which patients benefit from nonoperative versus surgically aggressive management strategies for acute appendicitis.

Comparative Study
Pre- and post-intervention study to assess the impact of a sedation protocol in critically ill surgical patients.
Sedation and pain management for mechanically ventilated critically ill surgical patients pose many challenges for the intensivist. Even though daily interruption of sedatives and opioids is appropriate in medical intensive care unit (ICU) patients, it may not be feasible in the surgical patients with pain from surgical incision or trauma. Therefore we developed an analgesia/sedation based protocol for the surgical ICU population. ⋯ In our cohort of critically ill surgery patients implementation of an ASP resulted in reduced use of continuously infused benzodiazepines and opioids, a decline in cumulative benzodiazepine and analgesic dosages, and a greater percentage of Richmond Agitation Sedation Scale scores at goal. We also showed reduced mechanical ventilation days.

Mild traumatic brain injury (TBI) is a serious public health concern affecting more than 1.7 million people in the United States annually. Mild TBI is difficult to diagnose and is clinically associated with impaired motor coordination and cognition. ⋯ The current study provides a reproducible model of mild TBI in mice that exhibits pathologic features of mild TBI in humans. Furthermore, our data suggest that serum cytokines, such as IL-6, may be effective biomarkers for severity of head injury.

Laparoscopic surgery has become the preferred approach in surgical practice due to multiple benefits. Over the last decade, kidney transplant by laparoscopic or robotic techniques have been explored. The aim of this study is to establish a new laparoscopic technique for kidney orthotopic transplant. ⋯ To our knowledge, this is the first study of laparoscopic kidney orthotopic transplant in pig model with satisfactory immediate graft function. It was demonstrated that laparoscopic kidney transplant is a feasible, reliable, and safe procedure. However, it is a very demanding technique. Adequate training is mandatory for performing laparoscopic kidney transplant. This study could be used as a training model for surgeons who wish to perform human laparoscopic kidney transplant in the future.
