In a previous study, we demonstrated that swine with metabolic syndrome treated with alcohol had improved insulin signaling. We developed a follow-up study to evaluate the effects of alcohol on ischemic myocardium in animals without metabolic syndrome. ⋯ Despite similar serum glucose and insulin levels, alcohol consumption up-regulates the insulin signaling pathway in the absence of metabolic syndrome in both nonischemic and chronically ischemic myocardium. These results suggest that alcohol selectively up-regulates the insulin signaling pathway despite normoglycemia.

Laparoscopic repair of paraesophageal hernia (PEH) has been shown to result in excellent relief of symptoms and improved quality of life (QOL) despite a high radiographically identified recurrence rate. Because there is no uniform definition of PEH recurrence, it is difficult to compare studies reporting on this. This study attempts to introduce consistency to the definition of PEH recurrence based on correlation of symptoms and radiographic findings. ⋯ Our analysis of symptom scores after laparoscopic PEH repair suggests that significant worsening occurs with RRH > 2 cm. Given that there is no consistent description of recurrent PEH, we suggest this as a possible standardized definition. Overall, patients with recurrent PEHs continue to experience excellent QOL and rarely require reoperation.

Traumatic brain injury and shock are among the leading causes of trauma-related mortality. We have previously shown that fresh-frozen plasma (FFP) resuscitation reduces the size of brain lesion and associated swelling compared with crystalloids. We hypothesized that this effect would be associated with an attenuation of circulating nucleosome levels, a biomarker of injury with cytotoxic potential, through reconstitution of circulating deoxyribonuclease-1 (DNAse1), an enzyme identified as critical in nucleosome clearance from the circulation. ⋯ Our results show that resuscitation with FFP attenuates circulating nucleosome levels and prevents DNAse1 depletion. These factors may play a role in the neuroprotective effects observed during early resuscitation with FFP.

Provider versus patient factors impacting hospital length of stay after pancreaticoduodenectomy.
Studies reporting perioperative outcomes after pancreaticoduodenectomy (PD) have focused on morbidity and mortality. Understanding factors that impact hospital duration of stay may have cost-saving implications. We sought to examine variation in duration of stay after PD occurring at the patient, surgeon, and hospital levels. ⋯ PD patients treated by higher volume surgeons and at higher volume hospitals had a shorter duration of stay. Although some patient-level factors impact duration of stay after PD, nonclinical factors such as surgeon and hospital volume were also important contributors to duration of stay.

The increasing prevalence of obesity has altered the practice of medicine and surgery, with the emergence of new operations and medications. We hypothesized that the landscape of medical malpractice claims has also changed. ⋯ Recently, the percentage of paid general surgery obesity claims has significantly decreased; however, individual and total indemnity payments have increased. Obesity continues to impact general surgery malpractice substantially. Efforts to manage this component of physician and hospital practices must continue.
