Postoperative pulmonary complications are common in these patients.

MMP-9 Deletion Attenuates Arteriovenous Fistula Neointima through Reduced Perioperative Vascular Inflammation.

Matrix metalloproteinase 9 (MMP-9) expression is upregulated in vascular inflammation and participates in vascular remodeling, including aneurysm dilatation and arterial neointima development. Neointima at the arteriovenous (AV) fistula anastomosis site primarily causes AV fistula stenosis and failure; however, the effects of MMP-9 on perioperative AV fistula remodeling remain unknown. Therefore, we created AV fistulas (end-to-side anastomosis) in wild-type (WT) and MMP-9 knockout mice with chronic kidney disease to further clarify this.

Oral Charcoal Adsorbents Attenuate Neointima Formation of Arteriovenous Fistulas.

Chronic kidney disease (CKD) accelerates the development of neointima formation at the anastomosis site of arteriovenous (AV) fistulas. Accumulation of certain uremic toxins has a deleterious effect on the cardiovascular system. The oral charcoal adsorbent, AST-120, reduces circulating and tissue uremic toxins, but its effect on neointima formation at an AV fistula is unknown.

Albumin supplementation may have limited effects on prolonged hypoalbuminemia in major burn patients: An outcome and prognostic factor analysis.

Background: Burns that affect ≥20% of the total body surface area (TBSA) trigger a major inflammatory response in addition to capillary leakage and loss of serum proteins including albumin. Persistent hypoalbuminemia is therefore common in major burn patients. The purpose of this study was to determine whether human albumin solutions can benefit major burn patients with persistent hypoalbuminemia.
