Large-volume, rapid crystalloid infusion may increase endothelial cell damage and induce shear stress, potentially leading to multiple-organ dysfunction syndrome. Limited guideline data for fluid administration are currently available, especially for the aging population. The aim of the present study was to compare the degree of organ damage in conscious aging rats when different resuscitation speeds were used during the treatment of hemorrhagic shock (HS). ⋯ The slow and continuous (12 h) fluid resuscitation rate ameliorated HS-induced organ damage in conscious aging rats.

Turnover time (TOT) is one of the classic measures of operating room (OR) efficiency. There have been numerous efforts to reduce TOTs, sometimes through the employment of a process improvement framework. However, most examples of process improvement in the TOT focus primarily on operational changes to workflows and statistical significance. These examples of process improvement do not detail the complex organizational challenges associated with implementing, expanding, and sustaining change. ⋯ There are obstacles, such as organizational culture and institutional inertia, that OR leaders, managers, and change agents commonly face. Awareness of the numerous variables that may support or impede a particular change effort can inform effective change implementation strategies that are "organizationally compatible."

Prehospital treatment for noncompressible abdominal bleeding, particularly due to large vascular injury, represents a significant unmet medical need on the battlefield and in civilian trauma. To date, few large animal models are available to assess new therapeutic interventions and hemostatic agents for prehospital hemorrhage control. ⋯ A new injury model is presented that enables screening of prehospital interventions designed to control noncompressible arterial hemorrhage.

Epigenetic programming, dynamically regulated by histone acetylation, may play a key role in the pathophysiology of sepsis. We examined whether histone deacetylase (HDAC) can contribute to sepsis-associated inflammation and apoptosis. ⋯ These findings imply that HDAC inhibitors are a unique agent to prevent cell apoptosis in sepsis at their doses that do not improve inflammatory features, indicating that septic inflammation and apoptosis may not necessarily be essential for one another's existence. This study also represents the first report that CLP-induced sepsis downregulates HDACs. Nevertheless, the data with HDAC inhibitors suggest that imbalance in histone acetylation may play a contributory role in expression or repression of genes involved in septic cell apoptosis.

Comparative Study Clinical Trial
Short-term outcomes of laparoscopically assisted surgery for rectal cancer following neoadjuvant chemoradiotherapy: a single-center experience.
The efficacy of laparoscopic treatment of rectal cancer remains unclear, and little is known about its effect on sphincter preservation. We compared short-term outcomes of laparoscopically assisted and open surgeries following neoadjuvant chemoradiotherapy (CRT) for mid and low rectal cancer. ⋯ Laparoscopically assisted surgery following neoadjuvant CRT is safe for patients with rectal cancer and provides favorable short-term benefits but without compromising oncologic outcomes. This sphincter-preserving procedure may be a treatment of choice for patients with lower rectal cancer.
