A Review of Occlusion as a Tool to Assess Attentional Demand in Driving
2021
Objective The aim of this review is to identify how visual occlusion contributes to our understanding of attentional demand and spare visual capacity in driving and the strengths and limitations of the method. Background The occlusion technique was developed by John W. Senders to evaluate the attentional demand of driving. Despite its utility, it has been used infrequently in driver attention/inattention research. Method Visual occlusion studies in driving published between 1967 and 2020 were reviewed. The focus was on original studies in which the forward visual field was intermittently occluded while the participant was driving. Results Occlusion studies have shown that attentional demand…
Embolization with ethylene vinyl alcohol copolymer (Onyx®) for peripheral hemostatic and non-hemostatic applications: a feasibility and safety study
2018
International audience; Background: Onyx® is a liquid embolic agent, which is approved for the treatment of cerebral vascular lesions but still rarely used in peripheral interventional radiology. The goal of this study is to report the feasibility and safety of embolization with Onyx® for peripheral hemostatic and non-hemostatic endovascular procedures.Methods: Retrospective study of all consecutive patients who underwent visceral or peripheral embolization with Onyx® for hemostatic or non-hemostatic purpose in our department between May 2014 and November 2016. Demographic data, clinical presentation, underlying etiology, culprit vessel, endovascular procedure, pain during embolization, out…
Association of Birth Weight with Central and Peripheral Corneal Thickness in Adulthood-Results from the Population-Based German Gutenberg Health Stud…
2021
Low birth weight (BW) is associated with altered ocular geometry such as a steeper corneal shape in adulthood. However, it is unclear whether low birth weight affects corneal thickness development in the center or periphery in adulthood which may contribute to ocular disease. The purpose of this study was to investigate corneal thickness in former low birth weight individuals in adulthood. Methods: The German Gutenberg Health Study is a prospective, population-based study in which every participant (age range 40–80 years) was measured with Scheimpflug imaging (Pentacam HR, Oculus Optikgeräte GmbH, Wetzlar, Germany). BW was collected by self-reports. The relationship between birth weight and…
Calcification of the intracranial carotid artery and its relation to the clinical and angiographic picture: an angiographic classification of asterio…
1968
Fifty six patients with arteriosclerosis cerebri confirmed by X-rays examinations were clinically and angiographically studied. Calcifications of the carotid artery were found predominantly in human beings between the ages of 55 and 65 and more often among men than among women, the proportion being 2.5 to 1. Nearly all arteriosclerotic patients with calcium deposits in the carotid artery showed several neurological and mental deficits, the most frequent initial symptoms being motor disturbances. Angiographic anormalities found in these patients can be classed into 3 groups: (a) grade I— wavy course of the cerebral vessels, small number of peripheral brain vessels, formation of small knots, …

. Aims of the study were explore the relationship between peripheral chromatic and central visual dysfunction evaluating also the presence of functional receptor impairment in patients with migraine, with and without aura examined interictally.
Remote photoplethysmography system for unsupervised monitoring regional anesthesia effectiveness
2017
Determining the level of regional anesthesia (RA) is vitally important to both an anesthesiologist and surgeon, also knowing the RA level can protect the patient and reduce the time of surgery. Normally to detect the level of RA, usually a simple subjective (sensitivity test) and complicated quantitative methods (thermography, neuromyography, etc.) are used, but there is not yet a standardized method for objective RA detection and evaluation. In this study, the advanced remote photoplethysmography imaging (rPPG) system for unsupervised monitoring of human palm RA is demonstrated. The rPPG system comprises compact video camera with green optical filter, surgical lamp as a light source and a …
A Complex Combination of Microvascular and Macrovascular Diseases
2016
When FFR is larger than 0.80, a PCI is not justified. Transient microvascular dysfunction may, however, be associated with impaired hyperemia and falsely negative FFR. This case also emphasizes the dynamic nature of microvascular disease, and provides an example of both “typical” syndrome X and “less conventional” syndrome slow flow associated with increased peripheral resistances (see Chap. 35).
TCT-361 Heart Team Approach to CAD Management in Patients Undergoing Elective Vascular Surgery Who Have Asymptomatic Ischemia-producing Coronary Sten…
2018
Patients undergoing peripheral vascular surgery (PVS) are at increased risk of post-op MI/death due to unrecognized CAD. Coronary CTA-derived fractional flow reserve (FFRCT) reliably identifies lesion-specific ischemia (LSI) in stable chest pain patients but has not been used in PVS patients. We
Endothelin-1 concentrations in the internal jugular and azygous veins in multiple sclerosis patients: the results of a pilot study
2014
Objectives: In this pilot study we examined the potent vasoconstrictor, endothelin-1, in the blood of multiple sclerosis patients in the context of chronic cerebrospinal venous insufficiency hypothesis. For this purpose we measured endothelin-1 concentrations in blood samples that were obtained during selective catheterisation of the main veins draining the central nervous system: the internal jugular veins and the azygous vein. Material and methods: We measured endothelin-1 concentrations in peripheral blood in nine multiple sclerosis patients and five healthy controls. In multiple sclerosis patients this peptide was also evaluated in blood samples obtained from the internal jugular veins …
Phase IA/II Study of Oral LBH589, a Novel Deacetylase Inhibitor (DACi), Administered on 2 Schedules, in Patients with Advanced Hematologic Malignanci…
2007
Abstract LBH589 is a novel cinnamic acid hydroxamate DACi which induces apoptosis in multiple hematologic tumor cell lines in vitro at nanomolar levels. LBH589 has been administered orally, once-a-day, on Monday/Wednesday/Friday, every week (Arm 1) or every other week (Arm 2), in cycles of 28 days, to adult pts with advanced hematologic malignancies. A 3-parameter Bayesian logistic regression model guided dose escalation. To date, 61 pts, median age 67 yrs (range 16–87), 40 male, 21 female, have been enrolled: 33 pts in Arm 1 at dose levels (mg/dose) of 20 (9 pts), 30 (12 pts), 40 (10 pts), and 60 (2 pts); 28 pts in Arm 2 at dose levels (mg/dose) of 30 (7 pts), 45 (12 pts), and 60 (9 pts). …
