South Asian ethnicity is an independent risk factor for mortality after coronary artery bypass. We tested the hypothesis that this risk results from a greater inflammatory response to cardiopulmonary bypass (CPB). ⋯ South Asians develop an exacerbated systemic inflammatory response after CPB, which may contribute to the higher morbidity and mortality associated with coronary artery bypass in this population. These patients may benefit from targeted anti-inflammatory therapies designed to mitigate the adverse consequences resulting from this response.

Lactoferrin (LF) is a pleiotropic glycoprotein that is found in bodily secretions and is postulated to enhance the gastrointestinal barrier and promote mucosal immunity. Thus, the ability of talactoferrin, an oral recombinant form of human LF, to limit gut injury and the production of biologically active gut-derived products was tested using a rat model of trauma-hemorrhagic shock (T/HS). ⋯ These results provide a proof of principle that prophylactic dosing of oral talactoferrin can potentially protect the gut in a T/HS model and limit the production of biologically active factors in rat gastrointestinal tissue subjected to ischemia-reperfusion-type injuries.

The open abdomen (OA) is associated with significant morbidity and mortality, and its management poses a formidable challenge. Inability to achieve primary closure of the abdominal wall is one of the most severe complications of this technique. Factors influencing primary fascial closure, however, are unknown. This study aims to explore the influence of fluid volume overload on the application of vacuum-assisted and mesh-mediated fascial traction (VAWCM) in OA treatment. ⋯ The VAWCM method provided a high primary fascial closure rate after long-term treatment of OA. Fluid volume overload negatively influences delayed primary facial closure. Judicious intravenous fluid resuscitation should be advocated in the therapy of critically ill patients.

Comparative Study
Quality of life in patients after total pancreatectomy is comparable with quality of life in patients who undergo a partial pancreatic resection.
Quality of life after total pancreatectomy (TP) is perceived to be poor secondary to insulin-dependent diabetes and pancreatic insufficiency. As a result, surgeons may be reluctant to offer TP for benign and premalignant pancreatic diseases. ⋯ Although TP-induced diabetes negatively impacts select activities and functions, overall quality of life is comparable with that of patients who undergo a partial pancreatic resection.

Activated macrophage infiltration into the lungs is paramount in the pathogenesis of acute lung injury (ALI) induced by intestinal ischemia-reperfusion (I/R). Omega-3 polyunsaturated fatty acid (ω-3 PUFA) is a potent activator of the Adenosine 5'-monophosphate-activated protein kinase-sirtuin1 (AMPK/SIRT1) pathway against macrophage inflammation. We aimed to evaluate whether ω-3 PUFAs may protect against ALI induced by intestinal I/R via the AMPK/SIRT1 pathway. ⋯ Pretreatment with ω-3 PUFAs effectively protects intestinal and lung injury induced by intestinal I/R, reduces macrophage infiltration, suppresses inflammation, inhibits lung apoptosis, and improves the lung endothelial barrier after intestinal I/R in a manner dependent on AMPK/SIRT1. Thus, there is a potential for developing AMPK/SIRT1 as a novel target for patients with intestinal I/R-induced ALI.
