Spinal cord injuries (SCIs) are sustained by more than 12 500 patients per year in the United States and more globally. The SCIs disproportionately affect the elderly, especially men. Approximately 60% of these injuries are sustained traumatically through falls, but nontraumatic causes including infections, tumors, and medication-related epidural bleeding have also been documented. Preexisting conditions such as ankylosing spondylitis and diffuse idiopathic skeletal hyperostosis can render the spine stiff and are risk factors as well as cervical spondylosis and ensuing cervical stenosis...

BACKGROUND: Arterial hypertension is the commonest cause of cardiovascular death. It may lead to hypertensive heart disease (HHD), including heart failure (HF), ischemic heart disease (IHD) and left ventricular hypertrophy (LVH). MAIN BODY: According to the 2007 ESH/ESC guidelines, the recommended imaging technique is echocardiography (echo), when a more sensitive detection of LVH than that provided by ECG, is needed. Cardiovascular Magnetic Resonance (CMR), a non-invasive, non-radiating technique, offers the following advantages, beyond echo: a) more reliable and reproducible measurements of cardiac parameters such as volumes, ejection fraction and cardiac mass b) more accurate differentiation of LVH etiology by providing information about tissue characterisation c) more accurate evaluation of myocardial ischemia, specifically if small vessels disease is present d) technique of choice for diagnosis of renovascular, aortic tree/branches lesions and quantification of aortic valve regurgitation e) technique of choice for treatment evaluation in clinical trials...

AIMS: Stem cell-based regenerative therapies for the treatment of ischemic myocardium are currently a subject of intensive investigation. A variety of cell populations have been demonstrated to be safe and to exert some positive effects in human Phase I and II clinical trials, however conclusive evidence of efficacy is still lacking. While the relevance of animal models for appropriate pre-clinical safety and efficacy testing with regard to application in Phase III studies continues to increase, concerns have been expressed regarding the validity of the mouse model to predict clinical results...

BACKGROUND: Ischemia, in the absence of obstructive coronary artery disease, is prevalent in women, and associated with increased risk for major cardiovascular events. Coronary microvascular dysfunction is prevalent in these patients, and associated with impaired diastolic function. Despite our general understanding, however, optimal treatment of this cohort remains elusive. METHODS: To address this knowledge gap, we performed an open-label treatment trial to assess whether phosphodiesterase type 5 inhibition improves coronary microvascular perfusion and diastolic function in women with signs and symptoms of ischemia but no evidence of obstructive coronary artery disease...

Myocardial reperfusion injury is a consequence of restoration of blood flow post ischemia. It is a complex process involving an acute inflammatory response activated by cytokines, chemokines, growth factors, and mediated by free radicals, calcium overload leading to mitochondrial dysfunction. Secretory phospholipases (sPLA2) are a group of pro-inflammatory molecules associated with diseases such as atherosclerosis, which increase the risk of reperfusion injury. This acute response leads to breakdown of phospholipids such as cardiolipin, found in the mitochondrial inner membrane, leading to disruption of energy producing enzymes of the electron transport chain...

Sepsis is a well-recognized healthcare issue worldwide, ultimately resulting in significant mortality, morbidity and resource utilization during and after critical illness. In its most severe form, sepsis causes multi-organ dysfunction that produces a state of critical illness characterized by severe immune dysfunction and catabolism. Sepsis induces the activation of complement factor via 3 pathways and the release of inflammatory cytokines such as tumor necrosis factor alpha (TNF-α) and interleukin-1beta (IL-1β), resulting in a systemic inflammatory response...

PURPOSE OF REVIEW: Critical limb ischemia (CLI) is associated with significant morbidity, mortality, and increased health care expenses. Revascularization has a central role in the treatment of CLI. Following publication of BASIL (bypass versus angioplasty in severe ischemia of the leg) trial a decade ago, an "endovascular first" approach had gained momentum and the technologies available for endovascular therapy have exponentially increased. Both the development of technology and technique, highlighted in this review, have allowed operators to treat complex infrapopliteal lesions which are central to CLI pathology...

Background Early, intensive statin treatment is the standard of care after acute coronary syndrome (ACS). However, the benefit of this approach to prevent major adverse cardiovascular events has been demonstrated in only one randomised, placebo controlled trial. The Myocardial Ischemia Reduction with Aggressive Cholesterol Lowering (MIRACL) trial demonstrated that atorvastatin 80 mg daily, compared with placebo, reduced time to first occurrence of death, non-fatal myocardial infarction, resuscitated cardiac arrest, or hospitalisation for unstable angina (stroke not included) during the 16 week period following ACS...

BACKGROUND: In a recent trial, cyclosporine A (CsA) failed to reduce infarct size in acute stroke patients treated with intravenous thrombolysis. White matter (WM) and gray matter (GM) may have distinct vulnerability to ischemia and response to therapy. Using final infarct size and lesion growth as endpoints, our objectives were to (1) investigate any tissue-specific effect of CsA and (2) compare WM and GM response to thrombolysis. MATERIALS AND METHODS: We analyzed 84 patients from the randomized and placebo-controlled CsA-Stroke trial, who underwent MRI both on admission and at 1 month...

Adenosine is known to be released under a variety of physiological and pathophysiological conditions to facilitate the protection and regeneration of injured ischemic tissues. The activation of myocardial adenosine A1 receptors (A1 Rs) has been shown to inhibit myocardial pathologies associated with ischemia and reperfusion injury, suggesting several options for new cardiovascular therapies. When full A1 R agonists are used, the desired protective and regenerative cardiovascular effects are usually overshadowed by unintended pharmacological effects such as induction of bradycardia, atrioventricular (AV) blocks, and sedation...

AIM: In patients with diabetes or ischemia, angiogenesis and infection control are required for chronic leg ulcers, which substantially impair patients' quality of life. We developed a novel functional peptide, named AG30/5C, with angiogenic and anti-microbial properties. Treatment with AG30/5C significantly accelerated the wound healing of full-thickness defects in mice. To evaluate the safety of AG30/5C in the treatment of leg ulcers, a physician-initiated clinical study was carried out...
