(1) To determine if antenna coupling occurs in common operating room scenarios. (2) To define modifiable clinical variables that reduce the magnitude of antenna coupling. ⋯ Antenna coupling occurs in common operating room scenarios. Simple, practical measures by the surgeon, such as orienting the receiving antenna at a greater angle and with greater separation to the active electrode cord, or lowering the generator power setting reduce antenna coupling.

Extent of distal resection margins in rectal cancer surgery remains controversial. We set out to determine the long-term oncologic impact of resection margins in patients with locally advanced rectal cancer using a comprehensive pathologic whole-mount section analysis. ⋯ These results suggest that carefully selected patients with locally advanced rectal cancers who undergo neoadjuvant CMT can achieve excellent local control and DSS with a sphincter-sparing rectal resection and a margin distal clearance of 1 cm.

It is important to identify new sources of transplantable organs because of the critical shortage of donor organs. Tissue engineering holds the potential to address this issue through the implementation of decellularization-recellularization technology. ⋯ Our investigations show that pig kidneys can be successfully decellularized to produce renal ECM scaffolds. These scaffolds maintain their basic components, are biocompatible, and show intact, though thrombosed, vasculature.

The study examines the role inflammatory and tumor markers as biomarkers to preoperatively predict outcome in patients with epithelial appendiceal neoplasm undergoing cytoreduction and intraperitoneal chemotherapy. ⋯ The results from this investigation suggest that preoperative inflammatory markers in blood and serologic tumor markers may predict outcomes and are associated with tumor biology in patients with epithelial appendiceal neoplasm undergoing cytoreduction and intraperitoneal chemotherapy treatment.

The present meta-regression pools data from reports of long-term follow-up (>2 years) to assess durability of the efficacy associated with Roux-en-Y gastric bypass (RYGB) surgery. ⋯ Pooling data from multiple studies meta-analytically revealed that weight loss after RYGB is maintained over the long-term. Further investigation would be necessary to ascertain similar durability in comorbidity reduction after RYGB surgery.
