Methods: A retrospective review of a prospectively maintained YAP-TEAD Inhibitor 1 datasheet database was performed to identify CHF patients undergoing endovascular peripheral arterial intervention from 2004 to 2009. Demographics, comorbidities, procedural details, and outcomes were analyzed. Patients underwent duplex ultrasound imaging and clinical follow-up at scheduled intervals. Kaplan-Meier and Cox proportional hazards models were used to evaluate risk factors for loss of primary patency, secondary

patency, and limb salvage.

Results: Of 1220 patients undergoing intervention, 271 (22%) with documented congestive heart failure (CHF) underwent an intervention for claudication (22.5%) or critical limb ischemia (77.5%). Primary patency at 1 year was 51.9% +/- 2.5% among those with CHF vs 64.6% +/- 1.3% in those without CHF (P < .001); this disparity URMC-099 continued throughout

follow-up (P < .001). Patients with CHF also had reduced secondary patency throughout follow-up. Multivariate analysis showed CHF was an independent predictor of reduced primary patency (hazard ratio [HR], 1.2; 95% confidence interval [Cl] 1.0-1.4; P = .038) and secondary patency (HR, 1.5; 95% CI, 1.2-1.8; P < .001). In the setting of CHF, 1-year patency was 56.6% +/- 4.1% if the ejection fraction (EF) was >40% (n = 147) vs 43.2% +/- 3.5% if the EF was <40% (n = 124;

P < .001). Secondary patency was also significantly reduced in patients with EF <40% throughout follow-up compared with patients without CHF (n = 949) as well as those with CHF and EF >40% (P < .001). CHF with EF <40% was an independent predictor of reduced primary patency (HR, 1.4; 95% CI, 1.2-1.8; P < .01) and secondary patency (HR, 1.8; 95% CI, 1.3-2.3; P < .001). Limb salvage was also worse in patients with EF <40% (P = .038).

Conclusions: CHF is associated with MEK162 supplier reduced patency after peripheral endovascular intervention and is an independent risk factor for patency loss. Specifically, CHF and reduced EF (<40%) is a strong independent risk factor for patency loss. (J Vase Surg 2012;55:353-62.)”
“Developmental lead (Pb) exposure is associated with cognitive impairments in humans and rodents alike. In particular, impaired spatial learning and memory, as assessed using the Morris water maze (MWM), has been noted in developmentally Pb-exposed rats. Although sex and rearing environment can influence MWM performance in normal animals, the interactions of sex and rearing environment on the impact of developmental Pb exposure on hippocampal-dependent processes has not been well characterized. The present study examined the effects of perinatal exposure (i.e.
