OBJECTIVE: Ischemic colitis (IC) is a well-described complication of ruptured abdominal aortic aneurysms (rAAA). The purpose of this study was to compare the incidence of IC in patients with rAAA undergoing open (OR) vs. endovascular aneurysm repair (EVAR) at a single institution. In addition, we analyzed the incidence of ischemic colitis pre- and post- implementation of a formal rupture AAA protocol (rEVAR protocol). METHODS: A retrospective analysis of prospectively collected data on all patients presenting with rAAA to our institution between Jan 2002 and Oct 2013 was performed...

A 56-year old male with ischemic heart disease and an unremarkable preoperative echocardiogram underwent surgical coronary revascularization. An intraoperative post pump trans-esophageal echocardiogram (TOE) performed while the patient was being ventilated at a positive end expiratory pressure (PEEP) of 8 cm H2O demonstrated a right to left interatrial shunt across a patent foramen ovale (PFO). Whereas oxygen saturation was normal, a reduction of the PEEP to 3 cm H2O led to the complete resolution of the shunt with no change in arterial blood gases...

Since plant oils are believed to be better than animal fats for cerebrovascular and cardiovascular diseases, the effects of various plant oils and trans-fat on blood lipid profiles and ischemic stroke were investigated. Sprague-Dawley rats were fed a diet containing the oils or trans-fat, and then body weights, blood lipids, and effects on brain infarction and physical dysfunction induced by middle cerebral artery occlusion (MCAO) were analyzed. All the oils and trans-fat, except perilla oil, significantly increased body fats and body weight gain...

PURPOSE OF REVIEW: Platelet P2Y12 receptor inhibitors are routinely prescribed for patients after acute coronary syndromes and percutaneous coronary interventions. Patients may have underresponsiveness (or resistance) to these drugs and in particular to clopidogrel, the most often used type. This review aims to focus on the concept of P2Y12 receptor inhibitor resistance and discuss incidence, mechanisms, novel diagnostic techniques and past and future clinical trials on the topic. RECENT FINDINGS: Patients treated with P2Y12 receptor inhibitors may develop high on-treatment platelet reactivity (HPR), a phenomenon of impaired response toward the drug, which has been associated with ischemic complications...

Trans-resveratrol (tRESV), a polyphenol with antioxidant properties, is common in many food sources, hence easily accessible for study as a maternal dietary supplement in perinatal asphyxia (PA). Hypoxic-ischemic encephalopathy secondary to PA affects especially vulnerable brain areas such as hippocampus and is a leading cause of neonatal morbidity. The purpose of this study is to identify new epigenetic mechanisms of brain inflammation and injury related to PA and to explore the benefit of tRESV enriched maternal diet...

BACKGROUND: Among the problems encountered by plastic surgeons is the reconstruction of defects following tumors. One of the reconstructive options is trans rectus abdominis (TRAM) flap. Despite that anatomy is well explored, marginal flap necrosis may develop. To minimize the complications, imaging examinations were designed to determine the degree of flap perfusion. One of them is the thermographic examination. MATERIALS AND METHODS: We examined 38 patients who had undergone 10 reconstructive breast surgeries with a pedicled TRAM ipsilateral flap, 10 patients with a TRAM contralateral flap, and 18 patients with a TRAM supercharged flap...

The present study investigated the protective effects of small ubiquitin-like modifier 1 (SUMO-1) on spinal cord ischemic damage in rabbits. A trans‑activator of transcription (Tat)‑SUMO‑1 fusion protein was prepared, and transient spinal cord ischemia was induced by occlusion of the abdominal aorta for 15 min. Vehicle (glycerol) or 1 mg/kg Tat-1-SUMO‑1 was administered intraperitoneally to the rabbits immediately following ischemia/reperfusion. Administration of Tat-SUMO-1 did not lead to significant alterations in arterial blood gases [partial pressure (Pa)CO2 and PaO2], pH, or blood glucose levels prior to ischemia, 10 min after occlusion or 10 min after reperfusion...

Despite its low chemical reactivity, the noble gas xenon possesses a remarkable spectrum of biological effects. In particular, xenon is a strong neuroprotectant in preclinical models of hypoxic-ischemic brain injury. In this study, we wished to determine whether xenon retained its neuroprotective potential in experimental settings that model the progressive loss of midbrain dopamine (DA) neurons in Parkinson's disease. Using rat midbrain cultures, we established that xenon was partially protective for DA neurons through either direct or indirect effects on these neurons...

BACKGROUND: Non-traumatic out of hospital cardiac arrest (OHCA) is the leading cause of death worldwide, mainly due to acute coronary syndromes. Urgent coronary angiography with view to revascularisation is recommended in patients with suspected acute coronary syndrome. Diagnosis and management of patients with inconclusive coronary angiogram (unobstructed coronaries or unidentified culprit lesion) is challenging. We sought to assess the role of Cardiovascular Magnetic Resonance (CMR) in the diagnosis and management of OHCA survivors with an inconclusive coronary angiogram...
