Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal disease characterized by a prominent desmoplastic stroma that may constrain tumor progression but also limit the access of therapeutic drugs. In this study, we explored a tumor-targeting strategy that enlists an engineered anti-angiogenic protein consisting of endostatin and cytosine deaminase linked to uracil phosphoribosyltransferase (EndoCD). This protein selectively binds to tumor vessels to compromise tumor angiogenesis and converts the non-toxic 5-fluorocytosine (5-FC) to the cytotoxic 5-fluorouracil to produce a chemotherapeutic bystander effect at the pancreatic tumor site...

REVIEW
Fleur V Y Tjong, Vivek Y Reddy
A new technology, leadless pacemaker therapy, was recently introduced clinically to address lead- and pocket-related complications in conventional transvenous pacemaker therapy. These leadless devices are self-contained right ventricular single-chamber pacemakers implanted by using a femoral percutaneous approach. In this review of available clinical data on leadless pacemakers, early results with leadless devices are compared with historical results with conventional single-chamber pacing. Both presently manufactured leadless pacemakers show similar complications, which are mostly related to the implant procedure: cardiac perforation, device dislocation, and femoral vascular access site complications...

BACKGROUND: Some electrophysiological techniques, such as balloon cryoablation, involve the use of steerable sheaths of large diameter (outer diameter 15Fr or more). Their introduction to the femoral vein may be difficult, especially in patients who have had numerous venipunctures in this area. The authors describe a modification of typical venous access with the use of a "buddy wire" technique, facilitating the insertion of the cryoablation sheaths to the femoral vein. METHODS: A case-control study...

REVIEW
Junji Terao
Nowadays dietary flavonoids attract much attention in the prevention of chronic diseases. Epidemiological and intervention studies strongly suggest that flavonoid intake has beneficial effects on vascular health. It is unlikely that flavonoids act as direct antioxidants, although oxidative stress profoundly contributes to vascular impairment leading to cardiovascular diseases. Instead, flavonoids may exert their function by tuning the cellular redox state to an adaptive response or tolerable stress. However, the optimum intake of flavonoids from supplements or diet has not been clarified yet, because a number of exogenous and endogenous factors modulating their bioavailability affect their vascular function...

BACKGROUND: The arteriovenous fistula (AVF) is the preferred form of hemodialysis access for patients with chronic kidney disease. However, AVFs are associated with significant problems including high incidence of both early and late failures, usually attributed to inadequate venous arterialization and neointimal hyperplasia, respectively. Understanding the cellular basis of venous remodeling in the setting of AVF could provide targets for improving AVF patency rates. METHODS AND RESULTS: A novel vascular smooth muscle cell (VSMC) lineage tracing reporter mouse, Myh11-Cre/ERT2-mTmG, was used to track mature VSMCs in a clinically relevant AVF mouse model created by a jugular vein branch end to carotid artery side anastomosis...

The left ventricular ejection time is routinely measured from a peripheral arterial waveform. However, the arterial waveform undergoes constant transformation as the pulse wave propagates along the arterial tree. Our goal was to determine if the left ventricular ejection time measured peripherally in the arterial tree accurately reflected the ejection time measured through the aortic valve. Moreover, we examined/accessed the modulating influence of hemodynamics on ejection time measurements. Continuous wave Doppler waveform images through the aortic valve and the simultaneously obtained radial artery pressure waveforms were analyzed to determine central and peripheral ejection times, respectively...

Patients relying on central venous access devices (CVADs) for treatment are frequently complex. Many have multiple comorbid conditions, including renal impairment, nutritional deficiencies, hematologic disorders, or cancer. These conditions can impair the skin surrounding the CVAD insertion site, resulting in an increased likelihood of skin damage when standard CVAD management practices are employed. Supported by the World Congress of Vascular Access (WoCoVA), developed an evidence- and consensus-based algorithm to improve CVAD-associated skin impairment (CASI) identification and diagnosis, guide clinical decision-making, and improve clinician confidence in managing CASI...

INTRODUCTION: The patency of long-term hemodialysis access in end-stage renal disease (ESRD) patients remains a significant challenge. Often these patients are affected with limited venous outflow options, requiring limb abandonment and creation of new access in the contralateral arm. Vascular surgeons are familiar with the exposure of the proximal axillary artery via an infraclavicular incision. The axillary vein is easily exposed through this technique. The use of the hybrid Gore graft can make the venous anastomosis easier...
