The Surgical Recovery Score (SRS) is a validated, comprehensive recovery assessment tool used to measure functional recovery after major surgery. To further evaluate its clinical applicability, this study investigated whether the SRS correlates with clinical outcomes and the occurrence of complications after elective colectomy. ⋯ In addition to measuring functional recovery, the SRS closely correlates with the development of complications after elective colectomy and offers a reliable outcome measure to assess overall postoperative recovery.

The insertion of gastrostomy tube (GT) for children is typically accomplished using a minimally invasive approach. There is considerable variability in the technical details of this operation, depending on how much of the procedure is performed intracorporeal. The purpose of this study is to compare the outcomes and resource utilization of two differing techniques for laparoscopic GT insertion in the pediatric population. ⋯ Pediatric patients undergoing laparoscopic gastrostomy tube insertion via the Seldinger or MOT method have similar morbidity risks, although MOT was associated with less overall resource utilization in this study.

Tumor necrosis factor-α (TNF-α), a cytotoxic cytokine, induces endothelial cell barrier dysfunction and microvascular hyperpermeability, leading to tissue edema, a hallmark of traumatic injuries. The objective of the present study was to determine whether B-cell lymphoma-extra large (Bcl-xL), an antiapoptotic protein, would regulate and protect against TNF-α-mediated endothelial cell barrier dysfunction and microvascular hyperpermeability. ⋯ Our results have demonstrated the protective effects of recombinant Bcl-xL protein against TNF-α-induced endothelial cell adherens junction damage and microvascular endothelial cell hyperpermeability. These findings support the potential for Bcl-xL-based drug development against microvascular hyperpermeability and tissue edema.

Among patients with breast cancer, obesity has been associated with an increased likelihood of having triple-negative breast cancer (TNBC). This association has been thought to be due to the antiapoptotic effects of obesity-related proteins. However, the effect of obesity on the outcomes in patients with TNBC remains unclear. We hypothesized that obesity would be associated with decreased overall survival and disease-free survival in these patients. ⋯ Despite an increased frequency of larger tumors, higher T stage, and higher tumor grade, obesity was not associated with decreased overall or disease-free survival in patients with TNBC.

Night-float work schedules were designed to address growing concerns of the affect of fatigue on resident psychomotor and cognitive skills after traditional 24-h call work schedules. Whether this transition has achieved these results is debatable. This study was designed to compare the psychomotor performance of general surgery residents on both work schedule types. We hypothesized that when measured with novel laparoscopic simulator tasks, residents on a 24-h call schedule would exhibit worse psychomotor performance compared with those on a night-float work schedule. ⋯ In this study of general surgery residents, a statistically significant difference in psychomotor performance between residents working 24-h call shift versus a 12-h night-float shift could not be found. Psychomotor performance does not appear to suffer after a work shift. Additionally, post-shift subjective evaluations of fatigue are comparable regardless of shift type.
