Kevin P Collins, Christopher J Russian, Joshua F Gonzales
The radial artery puncture is a frequently ordered medical procedure for patients requiring blood gas analysis. Deviating from the proper procedure increases the likelihood of error and jeopardizes patient safety. The teaching methodology for the radial artery puncture is rarely addressed in the medical literature. First-year respiratory care students enrolled in a clinical practice course participated in an expanded curriculum on arterial puncture technique. The new five-step curriculum included: 1) a face-to-face lecture, 2) radial artery localization, 3) blunt-tipped needle simulation, 4) manikin arm puncture, and 5) a peer assessment video...

BACKGROUND: Cholesterol-dependent and independent mechanisms were proposed to explain anti-atherosclerotic action of statins in humans. However, their effects in murine models of atherosclerosis have not been consistently demonstrated. Here, we studied the effects of pravastatin on atherosclerosis in ApoE/LDLR(-/-) mice fed a control and atherogenic diet. METHODS: ApoE/LDLR(-/-) mice were fed a control (CHOW) or an atherogenic (Low Carbohydrate High Protein, LCHP) diet...

INTRODUCTION: Shock, defined as a state of tissue hypoperfusion and the tissues reperfusion, is the main goal of management of shock. Increase in central venous saturation (CvSo2) and decrease in blood lactate level are useful in assessment of adequacy of tissue perfusion. Near-infrared spectroscopy is a noninvasive way to observe real-time changes in regional cerebral saturation and has been used in patients with different brain diseases. There is a small body of literature suggesting that cerebral regional oxygen saturation (CrSo2) monitoring added a value in assessment and management of intensive care unit (ICU) patients...

Stroke risk stratification based on grayscale morphology of the ultrasound carotid wall has recently been shown to have a promise in classification of high risk versus low risk plaque or symptomatic versus asymptomatic plaques. In previous studies, this stratification has been mainly based on analysis of the far wall of the carotid artery. Due to the multifocal nature of atherosclerotic disease, the plaque growth is not restricted to the far wall alone. This paper presents a new approach for stroke risk assessment by integrating assessment of both the near and far walls of the carotid artery using grayscale morphology of the plaque...

Endothelial dysfunction is crucial in the initiation of atherosclerosis, which is associated with a lack of nitric oxide. The endothelial NO synthase (eNOS) is responsible for constitutive synthesis of NO and inhibited by caveolin-1 (Cav1). In the current study, we examined the influence on intima formation through single and combined deletion of eNOS and Cav1 with a focus on differentiation of local and systemic effects. A sex-mismatch transplantation of denudated aortae from female C57BL/6n (WT), Cav1(-/-), eNOS(-/-) and Cav1(-/-)/eNOS(-/-) (C/e(--/--)) mice in common carotid artery of male WT mice was performed...

Glucose-6-phosphate dehydrogenase (G6PD) deficiency represents one of the most common erythrocyte enzymopathy. In the era of drug-eluting stents (DESs), the use of prolonged dual antiplatelet therapy (DAPT) with aspirin (ASA) and thienopyridine (clopidogrel or ticlopidine) has become mandatory in the treatment of patients with acute coronary syndromes (ACS) and/or after percutaneous coronary intervention (PCI). However, the use of ASA, and more in general of antiplatelet drugs in patients with G6PD deficiency remains controversial, also for the absence of specific guidelines and scientific evidences...

Anterior ischemic optic neuropathy (AION) is a relatively common cause of visual loss and results from hypoperfusion of the small arteries of the anterior portion of the optic nerve. AION is the leading cause of sudden optic nerve related vision loss with approximately 10 cases per 100'000 in the population over 50 years. To date there is no established treatment for AION and therefore a better understanding of the events occurring at the level of the optic nerve head (ONH) would be important to design future therapeutic strategies...
