BACKGROUND: The goal of carotid artery stenting (CAS) is to decrease the stroke risk in patients with carotid stenosis. This procedure carries an immediate risk of stroke and death and many patients do not benefit from it, especially asymptomatic patients. Patient selection for carotid procedure who benefit from procedure and who is the procedure hazardous for is important. Remote ischemic stroke is known risk factor for stroke reccurence during surgery. The aim of our study was to determine the periprocedural complication risk (within 30 days after CAS) associated with carotid stenting (stroke, death) between patients with remote pre- procedural ischemic stroke and without it; to analyse periprocedural risk in other specific patient subgroups treated with CAS and to determine the impact of observed variables on all- cause mortality during long-term follow-up...

Rotation thromboelastometry is a viscoelastometric method that provides a rapid assessment of a patient's hemostatic processes in emergency settings, allowing prompt identification of specific coagulation abnormalities. Its results thus might guide targeted replacement therapy in hemorrhagic conditions, in case of platelet or coagulation factor deficiency, or hyperfibrinolysis, which is difficult to identify otherwise. Although currently used in emergency and traumatic surgery, there are limited data about thromboelastometry in ischemic stroke, particularly in monitoring the coagulative response to recombinant tissue plasminogen activator after intravenous thrombolysis (IVT)...

Acute kidney injury is a common and serious complication with a huge impact on morbidity and short- as well as long-term mortality. Sepsis and major surgeries, especially cardiac surgery, are the most common causes of acute kidney injury. Slight increases of serum-creatinine levels are associated with adverse outcomes highlighting the relevance of the need for nephroprotective strategies to reduce the occurrence of acute kidney injury. Remote ischaemic preconditioning is an intervention consisting of brief episodes of ischaemia and reperfusion at a remote site before subsequent ischaemic insults occur...

PURPOSE: Therapeutic strategies that modulate ventricular remodeling can be useful after acute myocardial infarction (MI). In particular, statins may exert effects on molecular pathways involved in collagen metabolism. The aim of this study was to determine whether treatment with atorvastatin for 4 weeks would lead to changes in collagen metabolism and ventricular remodeling in a rat model of MI. METHODS: Male Wistar rats were used in this study. MI was induced in rats by ligation of the left anterior descending coronary artery (LAD)...

Delayed intracranial hemorrhage is a rare complication of treatment for central nervous system tumors. This may be secondary to malignant transformation of the tumor or vasculopathy related to radiation therapy (RT). While most reports on radiation-induced vasculopathy in children with optic pathway gliomas are associated with ischemic complications, there are only two reports of hemorrhagic complications in these patients. In both cases, the hemorrhage was asymptomatic and remote from the site of the original tumor but within the field of irradiation...

BACKGROUND: Autonomic remodeling, characterized by sympathetic activation and vagal withdrawal, contributes to heart failure (HF) progression. However, the exact mechanism(s) responsible for vagal withdrawal in HF remain(s) unclear, and whether HF causes epicardial autonomic nerve remodeling is unknown. METHODS AND RESULTS: Myocardial infarction (MI) was produced in 14 Sprague-Dawley rats, and 10 sham surgery rats served as the control. MI-HF was confirmed 2 months after the surgery by echocardiography and hemodynamic measurement...

We present an investigation on the generation of supercontinuum in the mid-infrared (mid-IR) spectral region. Namely, we study a silica-based anti-resonant hollow-core fiber which has good guidance properties in the mid-IR filled with supercritical xenon providing the necessary high nonlinearity. Our numerical study shows that by launching a 200 nJ pump of 100 fs centered at 3.70 μm, a supercontinuum that spans from 1.85 to 5.20 μm can be generated. Such sources are potentially useful for applications, such as the remote sensing of various molecules, medical imaging diagnosis, and surgery...

INTRODUCTION: Torso bleeding remains the most preventable cause of post-traumatic death worldwide. Remote Damage Control Resuscitation (RDCR) endeavours to rescue the most catastrophically injured, but has not focused on pre-hospital surgical torso haemorrhage control (HC). We examined the logistics and metrics of intra-peritoneal packing in weightlessness in Parabolic flight (0g) compared to terrestrial gravity (1g) as an extreme example of surgical RDCR. METHODS: A surgical simulator was customized with high-fidelity intra-peritoneal anatomy, a "blood" pump and flow-meter...

Ischemia/reperfusion (I/R) is one of the main causes of acute kidney injury (AKI), which is characterized by sterile inflammation and oxidative stress. Immune cell activation can provoke overproduction of inflammatory mediators and reactive oxygen species (ROS), leading to perturbation of the microcirculation and tissue oxygenation associated with local and remote tissue injury. This study investigated whether the clinically employed immunosuppressant mycophenolate mofetil (MMF) was able to reduce I/R-induced renal oxygenation defects and oxidative stress by preventing sterile inflammation...

BACKGROUND: Hepcidin regulates systemic iron homeostasis by downregulating the iron exporter ferroportin. Circulating hepcidin is mainly derived from the liver but hepcidin is also produced in the heart. We studied the differential and local regulation of hepcidin gene expression in response to myocardial infarction (MI) and/or chronic kidney disease (CKD). We hypothesized that cardiac hepcidin gene expression is induced by and regulated to severity of cardiac injury, either through direct (MI) or remote (CKD) stimuli, as well as through increased local iron content...

The strategy of Remote Ischaemic Conditionings (RIC) is easy to apply, cost effective, low in side effects and belongs to the most potent cardioprotective strategies evaluated within recent years. Its practical application is carried out by simple use of a blood pressure cuff, more precise by 4 repetitive cycles of inflating the cuff above 200 mmHg for 5 minutes followed by an equal long break between the cycles. First experimental and clinical data repetitively demonstrated a significant reduction in myocardial injury following ischemia/reperfusion...
