Sternal bone anatomy on preoperative imaging as an independent predictor of deep sternal dehiscence following median sternotomy.

Complications following median sternotomy are associated with morbidity, mortality, and major healthcare costs. With plastic surgeons being increasingly consulted to close complex sternotomy wounds, a more accurate risk stratification tool for this comorbid patient population is warranted. This study examines the association of preoperative radiologic sternal measurements and deep sternal dehiscence, comparing this with other known clinical risk factors.

Diagnostic Peritoneal Aspiration Revisited: Its Diagnostic Accuracy for the Detection of Intraabdominal Hemorrhage.

Background: The use of Focused Assessment with Sonography for Trauma (FAST) in combination with computed tomography (CT) has become the mainstay of diagnostic workup in patients with suspected intraabdominal hemorrhage (IAH). However, diagnostic peritoneal aspiration (DPA) can be an important adjunct in hemodynamically unstable patients. The aim of this study was to evaluate the utility and diagnostic accuracy of DPA in detecting IAH.

Performance of Focused Assessment with Sonography for Trauma Following Resuscitative Thoracotomy for Traumatic Cardiac Arrest.

Background: In patients undergoing resuscitative thoracotomy (RT) for traumatic cardiac arrest, focused assessment with sonography for trauma (FAST) is often used to look for intraperitoneal fluid. These findings can help determine whether abdominal exploration is warranted once return of spontaneous circulation is achieved; however, the diagnostic accuracy of FAST in this clinical scenario has yet to be evaluated. The purpose of this study was to assess the performance of FAST in identifying intra-abdominal hemorrhage following RT.

Paraoxonase 2 overexpression inhibits tumor development in a mouse model of ovarian cancer.

Ovarian cancer (OC) is most lethal malignancy among all gynecological cancer. Large bodies of evidences suggest that mitochondrial-derived ROS play a critical role in the development and progression of OC. Paraoxonase 2 (PON2) is a membrane-associated lactonase with anti-oxidant properties.
