Initial Post-Operative Visit Absenteeism is Associated With Worse Amputation-Free Survival after Tibial Angioplasty.

Objectives: Tibial revascularization is often performed in the setting of critical limb ischemia and tissue loss requiring close patient monitoring in the early post-operative period for worsening gangrene and/or ischemia. Multiple studies have shown loss to follow-up is an independent risk factor for poor outcomes in several vascular procedures. Therefore, we evaluated the risk factors relating to loss to follow up against outcomes in patients undergoing tibial endovascular procedures with the hypothesis that poor post-operative visit compliance is associated with decreased amputation-free survival rates.

Frailty is a Poor Predictor of Postoperative Morbidity and Mortality After Ruptured Abdominal Aortic Aneurysm.

Background: Frailty has gained prominence as a predictor of postoperative outcomes across a number of surgical specialties, vascular surgery included. The role of frailty is less defined in the acute surgical setting. We assessed the prognostic value of frailty for patients undergoing surgery for a ruptured abdominal aortic aneurysm (rAAA).

Compliance with surgical follow-up does not influence fistula maturation in a county hospital population.

Background: The purpose of this study is to examine follow-up rates and maturation rates after dialysis access surgery using a fistula-first approach in a county hospital with an indigent population.

Methods: A prospectively maintained dialysis access database was queried for cases performed between August 1, 2009 and September 30, 2011. The follow-up period ended on December 31, 2011.

Stereotactic endovascular aortic navigation with a novel ultrasonic-based three-dimensional localization system.

Background: Endovascular aortic procedures have been developed to treat many aortic diseases effectively. However, these procedures are also becoming increasingly complex given the development of branched or fenestrated endografts. Part of the difficulty lies in the limitations of current imaging paradigms.

SINGLET OXYGEN RESISTANT 1 links reactive electrophile signaling to singlet oxygen acclimation in Chlamydomonas reinhardtii.

Acclimation of Chlamydomonas reinhardtii cells to low levels of singlet oxygen, produced either by photoreactive chemicals or high light treatment, induces a specific genetic response that strongly increases the tolerance of the algae to subsequent exposure to normally lethal singlet oxygen-producing conditions. The genetic response includes the increased expression of various oxidative stress response and detoxification genes, like the glutathione peroxidase homologous gene GPXH/GPX5 and the σ-class glutathione-S-transferase gene GSTS1. To identify components involved in the signal transduction and activation of the singlet oxygen-mediated response, a mutant selection was performed.
