We adopted a simple slide test and image analysis to determine the state of erythrocyte adhesiveness/aggregation in the peripheral blood of 45 patients with acute ischemic stroke, 30 with TIA and 27 matched controls. A highly significant (P=0.005) difference was noted between patients and controls regarding the degree of erythrocyte adhesiveness/aggregation while there was no significant difference for both erythrocyte sedimentation rate or fibrinogen concentrations. We suggest that our slide test might be a low cost and real time method to detect the increased erythrocyte aggregability in the peripheral blood of patients with acute ischemic neurological events. These findings might be relevant in view of recent studies that suggest a favorable effect of therapeutic interventions directed at the improvements of this hemorrheological aspect in individuals with ischemic vascular conditions.

Background: Red blood cell (RBC) aggregation influences blood flow properties, impacts blood microcirculation and consequently oxygen delivery. Different methods are established to determine RBC aggregation: under static conditions (i.e.

Objective: Stent implantation into atherosclerotic coronary vessels induces the release of particulate debris and soluble vasoactive substances, which impair downstream microvascular function. Microvascular perfusion, however, is also determined by hemorheological parameters. We therefore analyzed now changes in erythrocyte (RBC) aggregation in coronary arterial blood during stent implantation.

Unlabelled: A simple slide test and image analysis were used to reveal the presence of an acute-phase response and to determine its intensity in subjects of acute myocardial infarction and acute ischemic stroke. Erythrocytes tend to aggregate during an inflammatory process. Evaluation of erythrocyte adhesiveness/aggregation is currently available to the clinicians indirectly by erythrocyte sedimentation rate (ESR), but ESR correlates poorly with erythrocyte aggregation, hence a simple slide technique using citrated blood was used to evaluate erythrocyte aggregation microscopically and also by using image analysis.

Background: Obesity, a worldwide pandemia, is associated with a large variety of comorbidities, among which is non-alcoholic fatty liver disease. NAFLD is a complex disease that may eventually lead to cirrhosis, posing a high risk for the patient and thus necessitating early diagnosis and treatment.
Objectives: To evaluate the association between ultrasonographically diagnosed non-alcoholic fatty liver disease and the levels of serum inflammatory markers in obese children and adolescents.

Pulmonary Institute, Rabin Medical Center, Beilinson Campus, Petah Tiqwa 49100, Israel.
Background: Obstructive sleep apnea (OSA) is associated with an increased incidence of stroke and myocardial infarction as well as increased prothrombotic and inflammatory processes. Although erythrocyte adhesiveness/aggregation is known to be elevated in cardiovascular diseases, it has never been evaluated in OSA. The aim of this study was to examine the possible association of OSA and erythrocyte adhesiveness/aggregation.
