Over the past decade, there has been a major shift in chemotherapy from non-specific cytotoxic drugs to molecular targeted drug therapies. As more molecular targeted therapies are developed, new types of cardiovascular toxicities induced by targeted therapies are a growing problem. Cardiotoxicity induced by the human epidermal growth factor receptor-2 inhibitor trastuzumab manifests as decreased left ventricular ejection fraction. In contrast to anthracycline treatment, most cardiac events occur during trastuzumab treatment, but are reversed quickly when treatment is interrupted and cardiac intervention is established...

Peripheral arterial occlusive disease (PAOD), one of the major manifestations of systemic atherosclerosis, causes intermittent claudication and rest pain. Patients with PAOD not only have reduced quality of life, but also have a substantial risk of cardiovascular morbidity and death. In this study, we adopted a proteomics-based approach using 2D-DIGE and MALDI-TOF MS to compare the differential plasma proteome between good and poor prognosis of PAOD. We identified 196 plasma proteins, which represent 42 unique gene products...

In the current era, endovascular treatment of long femoropopliteal lesions (>15 cm) is becoming more feasible and favorable, with patency rates that rival surgical outcomes. Drug-coated balloons offer promising results at least to one year follow up although randomized, controlled trials to evaluate its efficacy compared to other treatment modalities (surgical and endovascular alike) is lacking at this time.

BACKGROUND: Intermittent claudication (IC) is a common condition that causes pain in the lower limbs when walking and has been shown to severely impact the quality of life (QoL) of patients. The QoL is therefore often regarded as an important measure in clinical trials investigating intermittent claudication. To date, no consensus exits on the type of life questionnaire to be used. This review aims to examine the QoL questionnaires used in trials investigating peripheral arterial disease (PAD)...

Diabetes mellitus is associated with an increased risk of falls, which increases the incidence of osteoporotic fractures and accordingly decreases quality of life. However, the association between fall risk and diabetic complications is not completely understood. Therefore, the aim of this study was to examine the association between fall risk and osteoporotic fractures in patients with type 2 diabetes mellitus (T2DM). We enrolled 194 Japanese patients with T2DM and assessed their fall risk using a brief interview form that included five items covering physical and social aspects of functioning and environmental factors...

Nicotinamide phosphoribosyltransferase (NAMPT) is an important neuroprotective factor in cerebral ischemia, and it has been reported that NAMPT inhibitors can aggravate neuronal injury in the acute phase. However, because it is a cytokine, NAMPT participates in many inflammatory diseases in the peripheral system, and its inhibitors have therapeutic effects. Following cerebral ischemia, the peripheral and resident inflammatory and immune cells produce many pro-inflammatory mediators in the ischemic area, which induce neuroinflammation and impair the brain...

OBJECTIVE: Concern over perioperative and long-term durability of lower extremity revascularizations among active smokers is a frequent deterrent for vascular surgeons to perform elective lower extremity revascularization. In this study, we examined perioperative outcomes of lower extremity endovascular (LEE) revascularization and open lower extremity bypass (LEB) in active smokers with intermittent claudication (IC) and critical limb ischemia (CLI). METHODS: Active smokers undergoing LEE or LEB from 2011 to 2014 were identified in the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) targeted vascular data set...

It is not uncommon that patients with peripheral arterial disease (PAD) need to undergo a lower limb amputation, with or without previous revascularization attempts. Despite that, the patient's experience of the amputation has been scarcely studied. The aim of this qualitative study was to describe the patient's experience of amputation due to PAD. Thirteen interviews were conducted with vascular patients who had undergone a lower limb amputation at tibia, knee, or femoral level. Data were analyzed with content analysis...

INTRODUCTION: Despite improvements in revascularization, major amputation remains a significant part of the case-mix in vascular surgical units. These patients tend to be elderly with complex pathology, resulting in poor outcomes and longer lengths of stay (LOS). AIM: This series review provides a description of the patient complexities and outcomes in an Australian cohort undergoing major lower limb amputation for peripheral arterial disease. METHOD: Medical records coded for major amputation between July 2012 and June 2013 in an Australian government funded, tertiary hospital were retrospectively reviewed and descriptively analyzed...

BACKGROUND AND AIMS: Many coronary artery disease (CAD) patients exhibit chronic low-grade inflammation. Carotenoids are anti-oxidants with potential anti-inflammatory properties. Here, we first assessed relationships between interleukin (IL)-6 and individual carotenoids in plasma from CAD patients. Based on the results, we proceeded to assess anti-inflammatory effects of one carotenoid, lutein, in peripheral blood mononuclear cells (PBMCs) from CAD patients. METHODS: Lutein + zeaxanthin (isomers with lutein being dominant), β-cryptoxanthin, lycopene, α- and β-carotene and IL-6 were measured in plasma from 134 patients with stable angina (SA) and 59 patients with acute coronary syndrome...

The number of patients suffering from peripheral arterial occlusive disease (PAOD) is growing worldwide. PAOD corresponds to an impairment of perfusion in the distal portion of some arteries that can generate critical limb ischemia. For some patients, the pathology leads to the necessity of amputation. PAOD may be diagnosed and studied with transcutaneous oxygen (tcpO2) measurements. However, the tcpO2 technique is a contact technique: probes have to be positioned on the limb, which may be impossible in case of ulcers and can lead to infection risks...

Previous studies have suggested that the risk of ischemic stroke increases immediately after drinking coffee. Indeed, drinking coffee, that is, caffeine, acutely increases arterial stiffness as well as blood pressure and peripheral vascular resistance. On the other hand, it has been reported that arterial stiffening is associated with elevation in the pulsatility index (PI) of cerebral blood flow (CBF), which increases the risk of brain disease. However, the effect of drinking coffee on the PI of the CBF and its interaction with arterial stiffness remain unknown...

BACKGROUND: High failure rates of femoropopliteal artery (FPA) interventions are often attributed in part to severe mechanical deformations that occur with limb movement. Axial compression and bending of the FPA likely play significant roles in FPA disease development and reconstruction failure, but these deformations are poorly characterized. The goal of this study was to quantify axial compression and bending of human FPAs that are placed in positions commonly assumed during the normal course of daily activities...

OBJECTIVE: Supplementation of glutathione (GSH) may be a positive strategy to improve the endogenous antioxidant defense required to counteract many acute and chronic diseases. However, the efficacy of GSH treatment seems to be closely related to type of administration, degree of absorption, and increase of its concentrations. The aim of this study was to test a new sublingual formulation of L-GSH, which enters directly the systemic circulation, to assess its efficacy on circulating biochemical markers of hepatic metabolism, lipid profile, and oxidative stress and on peripheral vascular function compared with placebo in patients with cardiovascular risk factors (CVRF)...

BACKGROUND: Increased carotid-femoral pulse wave velocity (PWV) has been associated with incident cardiovascular disease, independently of traditional risk factors. Cardiac autonomic dysfunction is a common complication of diabetes and has been associated with reduced aortic distensibility. However, the association of cardiac autonomic dysfunction with PWV is not known. In this study we examined the association between cardiac autonomic function and PWV in subjects with type 2 diabetes mellitus...

BACKGROUND: Severe limb ischaemia (SLI) is defined as the presence of rest pain and/or tissue loss secondary to lower extremity atherosclerotic peripheral arterial disease. The superficial femoral and popliteal arteries are the most commonly diseased vessels in such patients and are being increasingly treated using endovascular revascularisation techniques. However, it is currently unknown whether drug-eluting stents and drug-coated balloons confer additional clinical benefits over more established techniques using plain balloons and bare metal stents, or whether they represent a cost-effective use of NHS resources...
