BACKGROUND: Hemodialysis (HD) vascular access failure is one of the most important causes of morbidity and contributes to the cost of dialysis care. There is paucity of data evaluating long-term monitoring of C-reactive protein (CRP) on outcome of HD vascular access. METHODS: We conducted a retrospective study to investigate whether variability of serum CRP level was associated with vascular access failure rate over a 7-year period. A total of 318 HD patients were included...

Vascular remodeling is the primary cause underlying the failure of angioplasty surgeries, including vascular stenting, transplant vasculopathy and vein grafts. Multiple restenosis‑associated proteins and genes have been identified to account for this. In the present study, the functions of ubiquitin‑specific peptidase 39 (USP39) were investigated in the context of two vascular remodeling models (a mouse common carotid artery ligation and a pig bilateral saphenous vein‑carotid artery interposition graft)...

The Código Infarto (Infarction Code) strategy is part of the comprehensive care program "A Todo Corazón" (To All Heart), whose aim is to reinforce the prevention and health care of cardiovascular diseases. Mexico faces a big challenge, since it is the country with greater mortality secondary to acute myocardial infarction (AMI) in the first 30 days in patients of 45 years or older (28% compared with 7.9% of the average). In addition, Mexico's population has a high prevalence of risk factors (hypertension, diabetes, tobacco use, dyslipidemias, overweight, and obesity)...

As a common etiology for ischemic stroke, atherosclerotic carotid stenosis has been targeted by vascular surgery since 1950s. Compared with carotid endarterectomy, carotid angioplasty and stenting (CAS) is almost similarly efficacious and less invasive. These advantages make CAS an alternative in treating carotid stenosis. However, accumulative evidences suggested that the long-term benefit-risk ratio of CAS may be decreased or even neutralized by the complications related to in-stent restenosis (ISR). Therefore, investigating the mechanisms and identifying the influential factors of ISR are of vital importance for improving the long-term outcomes of CAS...

An adolescent girl, a known case of spina bifida with systemic lupus, presented with bluish discolouration of three toes of the right foot. She had thrombosis of bilateral popliteal arteries. She underwent percutaneous transluminal angioplasty (PTA) of both legs and Chopart amputation of the right foot. Systemic lupus erythematosus (SLE) occurring in a patient with spina bifida has not been previously reported. Weakness, sensory loss, lack of normal ambulation, endarteritis, antiphospholipid antibody syndrome are common contributory factors for peripheral gangrene in patients with spina bifida with systemic lupus erythematosus...

BACKGROUND: Systemic administrations of conventional antithrombotics reduce neointima formation after angioplasty in experimental animals. However, clinical translation of these results has not been successful due to high risk for bleeding. OBJECTIVES: We sought to determine whether novel annexin-V (ANV)-Kunitz protease inhibitor fusion proteins, TAP-ANV and ANV-6L15, can specifically target to vascular injury site and limit neointima formation without inducing systemic hypo-coagulation in a rat carotid artery balloon angioplasty injury model...

Roscovitine is a selective CDK inhibitor originally designed as anti-cancer agent, which has also been shown to inhibit proliferation in vascular smooth muscle cells (VSMCs). However, its effect on vascular remodeling and its mechanism of action remain unknown. In our study, we created a new intimal hyperplasia model in male Sprague-Dawley rats by trypsin digestion method, which cause to vascular injury as well as the model of rat carotid balloon angioplasty. Roscovitine administration led to a significant reduction in neointimal formation and VSMCs proliferation after injury in rats...

BACKGROUND: Considering that pneumonectomy itself is a disease, avoidance of pneumonectomy needs to be deliberated. Herein, we evaluated the role of neoadjuvant chemoradiotherapy for avoidance of pneumonectomy in patients with centrally located locally advanced non-small cell lung cancer. METHODS: Patients who underwent neoadjuvant chemoradiotherapy after being judged to require pneumonectomy by cancer board between 1997 and 2011 were retrospectively evaluated. RESULTS: Twelve patients, including 10 males and 2 females with median age 63...

OBJECTIVE: Balloon pulmonary angioplasty (BPA) is used for inoperable chronic thromboembolic pulmonary hypertension (CTEPH), but its effect cannot be evaluated noninvasively. We devised a noninvasive quantitative index of response to BPA using three-dimensional fractal analysis (3D-FA) of technetium-99m-macroaggregated albumin (Tc-MAA) single-photon emission computed tomography (SPECT). PATIENTS AND METHODS: Forty CTEPH patients who underwent pulmonary perfusion scintigraphy and mean pulmonary arterial pressure (mPAP) measurement by right heart catheterization before and after BPA were studied...

PURPOSE: To report patency rates for stent deployment for treatment of in-stent stenosis of the central veins of the chest in hemodialysis patients. MATERIALS AND METHODS: A retrospective analysis was performed on 29 patients who underwent 35 secondary percutaneous transluminal stent (PTS) deployments for in-stent stenosis within the central veins that were refractory to angioplasty and ipsilateral to a functioning hemodialysis access (in-stent PTS group). For comparison, patency data were acquired for 47 patients who underwent 78 successful percutaneous transluminal angioplasty (PTA) procedures for in-stent stenosis (in-stent PTA group) and 55 patients who underwent 55 stent deployments within native central vein stenosis refractory to angioplasty (native vein PTS group)...

The paper presents an applied methodology for numerical Finite Element analysis of coronary stent crimping and the free inflation process with the use of a folded non-compliant angioplasty balloon. The use of an implicit scheme is considered as the most original part of the work, as an explicit finite element procedure is very often preferred. Hitherto, when the implicit solution was used for the Finite Element solution, the simulated issue was largely simplified. Therefore, the authors focused on the modelling methodology with minimum possible simplification, i...
