OBJECTIVE: Prevalence of end-stage renal disease, modality of treatment, and type of hemodialysis vascular access used varies widely by race/ethnicity in the United States, but outcomes of hemodialysis vascular access by race/ethnicity are poorly described. The objective of this study is to evaluate variations in outcomes of hemodialysis vascular access in the elderly by race/ethnicity. METHODS: Medicare outpatient, inpatient, and carrier files were queried from 2006 to 2011 for beneficiaries that were age ≥66 years and dialysis-dependent at time of index fistula/graft creation, qualified for Medicare by age only, and were continuously enrolled in Medicare 12 months before and after index fistula/graft creation...

Delivery of a prescribed dialysis dose, which is critical for longevity on hemodialysis, is directly dependent on vascular access (VA). However, VA is fraught with high failure rates and has room for innovation. Arteriovenous fistula (AVF), considered the 'best choice', has a high 'failure to mature' rate. Arteriovenous grafts (AVGs) are considered when patients are poor candidates for or have failed AVF, but have a high incidence of infections and thrombosis. Due to associated morbidity and mortality from complications, central venous catheters are considered only as 'bridging short-term access' when there is an urgent need for dialysis...

BACKGROUND: Human settlements are of increasing interest to ecologists, a fact demonstrated by the recent cluster of book-length treatments of the topic (Forman 2008, McDonnell et al. 2009, Gaston 2010, Niemelä et al. 2011, Wilson 2011, Forman 2014). The natural world as a fascinating feature of towns and cities has a much longer history (e.g. Fitter 1945), and has also played a strong part in local biological conservation in some countries over the late 20th Century (Goode 2014​)...

AIMS: Complications from catheter ablation for atrial fibrillation (AF) are well described. Changing aspects of AF ablation including patient populations referred, institutional experience, and emerging catheter and pharmacological options may impact complication rates. We assessed procedural complication trends in AF ablation patients from 2003-2015 to identify what factors affect adverse event rates. METHODS AND RESULTS: We evaluated consecutively enrolled patients undergoing initial AF ablation from 2003 through 2015...

A vascular surgery clinic in an academic center faced many delays for patients in gaining access to an appointment. In January 2014, wait times from referral to patient appointment were estimated to be 3 to 4 weeks. A 6-month pilot project was conducted from January 2014 through June 2014 with the aim of scheduling 50% of new patients within 7 days of referral. The clinic manager, medical director, clinic staff, and clerical team worked in partnership to initiate a series of interventions to reduce the backlog of patients, implement scheduling guidelines, and use nurse practitioners to improve practice efficiencies...

BACKGROUND: Diffusion weighted (DW) cardiovascular magnetic resonance (CMR) has shown great potential to discriminate between healthy and diseased vessel tissue by evaluating the apparent diffusion coefficient (ADC) along the arterial axis. Recently, ex vivo studies on porcine arteries utilizing diffusion tensor imaging (DTI) revealed a circumferential fiber orientation rather than an organization in axial direction, suggesting dominant diffusion perpendicular to the slice direction. In the present study, we propose a method to access tangential and radial diffusion of carotids in vivo by utilizing a pulse sequence that enables high resolution DW imaging in combination with a two-dimensional (2D) diffusion gradient direction sampling scheme perpendicular to the longitudinal axis of the artery...

INTRODUCTION: Clinical information continues to be limited regarding changes in the temporal risk profile for readmissions during the initial postoperative year in vascular surgery patients. We set out to describe the associations between demographics, clinical outcomes, comorbidity indices, and hospital readmissions in a sample of patients undergoing common extremity revascularization or dialysis access (ERDA) procedures. We hypothesized that factors independently associated with readmission will evolve from "short-term" to "long-term" determinants at 30-, 180-, and 360-day postoperative cutoff points...

BACKGROUND: About one-third of candidates for transcatheter aortic valve implantation (TAVI) suffer from severe peripheral artery disease, making the routine femoral approach difficult or impossible. Aim was to compare the trans-axillary (TAx) and the trans-aortic (TAo) route for TAVI with Medtronic CoreValve Revalving System (CRS). METHODS: 242 (23%) out of 1049 consecutive TAVI with 18F CRS were treated in 4 high-volume Italian Centre through TAx (61%) and TAo (39%)...

Endovascular repair has evolved to become a viable mainstream treatment for aortic pathology in both acute and elective settings. As technology advanced, traditional anatomical barriers were progressively tackled using new devices and novel procedures, and there are now multiple options available to the vascular surgeon. In the abdominal aorta, advances in endovascular aneurysm repair have been in the treatment of hostile aortic necks using new sealing concepts and ancillary procedures, and in branch preservation using fenestrations and snorkels...

OBJECTIVE: Given the rarity of in-hospital pediatric emergency events, identification of gaps and inefficiencies in the code response can be difficult. In-situ, simulation-based medical education programs can identify unrecognized systems-based challenges. We hypothesized that developing an in-situ, simulation-based pediatric emergency response program would identify latent inefficiencies in a complex, dual-hospital pediatric code response system and allow rapid intervention testing to improve performance before implementation at an institutional level...

BACKGROUND: Diabetes mellitus is the most common cause of end stage kidney disease in the developed countries. Chronic kidney disease-mineral and bone disorder (CKD-MBD) develops with deteriorating of the renal functions. Diabetic patients on hemodialysis are characterized by low bone turnover, higher prevalence of severe and progressive vascular calcification with increased cardiovascular morbidity and mortality. The main factor which causes vascular calcification in patients with diabetic kidney disease (DKD) is poor glycemic control...

PURPOSE: Adequate and functional long-term vascular access (VA) is pivotal for the efficient hemodialysis (HD). It has been shown that the most reliable VA is autogenous arteriovenous fistulas (AVFs) as compared with arteriovenous grafts (AVGs) and vascular catheters (VCs). The vascular access register (VAR) has been established since 2010, and the 4-year trend of VA in Serbia is presented in this paper. METHODS: All HD centers in Serbia provided their data by fulfilling the questionnaire that included prevalent and incident HD patients on December 31, 2010-1013...
