Changes in Cognition, Depression and Quality of Life after Carotid Stenosis Treatment
2019
Background:Although several studies have evaluated the change of cognitive performance after severe carotid artery stenosis, the results still remain elusive. The objective of this study was to assess changes in cognitive function, depressive symptoms and Health Related Quality of Life (HRQoL) after carotid stenosis revascularisation and Best Medical Treatment (BMT).Methods:Study involved 213 patients with ≥70% carotid stenosis who underwent assessment of cognitive function using Montreal Cognitive Assessment scale (MoCA), depressive symptoms - using Patient Health Questionnaire-9 (PHQ-9) and HRQoL - using Medical Outcome Survey Short Form version 2 (SF-36v2). The assessment was performed b…
Haemodynamic predictors of a penetrating atherosclerotic ulcer rupture using fluid-structure interaction analysis
2013
We present preliminary data on the flow-induced haemodynamic and structural loads exerted on a penetrating atherosclerotic aortic ulcer (PAU). Specifically, one-way fluid-structure interaction analysis was performed on the aortic model reconstructed from a 66-year-old male patient with a PAU that evolved into an intramural haematoma and rupture of the thoracic aorta. The results show that elevated blood pressure (117 mmHg) and low flow velocity at the aortic wall (0.15 m/s(2)) occurred in the region of the PAU. We also found a low value of time-averaged wall shear stress (1.24 N/m(2)) and a high value of the temporal oscillation in the wall shear stress (oscillatory shear index = 0.13) in t…
Long-term outcomes of percutaneous coronary interventions or coronary artery bypass grafting for left main coronary artery disease in octogenarians (…
2014
Percutaneous coronary intervention (PCI) with drug-eluting stents is an accepted alternative to surgery for the treatment of unprotected left main coronary artery (ULMCA) disease, but the long-term outcome in elderly patients is unclear. Aim of our study was to compare the clinical outcomes of octogenarians with ULMCA disease treated either with PCI with drug-eluting stents or coronary artery bypass grafting (CABG). The primary study end point was the composite of death, cerebrovascular accident, and myocardial infarction at follow-up. A total of 304 consecutive patients with ULMCA stenosis treated with PCI or CABG and aged 80 years were selected and analyzed in a large multinational regist…
Coaches' reflections on the meaning and value of Masters athletics
2019
Masters sport is a growing social movement offering the opportunity to participate in competitive sports in later life. Although many studies have explored Masters athletes' experiences, little is known about how other actors in the sport subcultures construct meaning in Masters sport and whether their stories work to support or hinder participation. Our study explored the cultural narrative resources and life scripts surrounding sport and ageing that coaches draw upon in two European countries, England and Finland, where sport policy has put different emphasis on elite sport and sport for all. We analysed interviews from 23 athletics (track and field) coaches (8 women) to understand how th…
CLINICAL OUTCOMES OF SELF-EXPAMDABLE METALLIC STENTS IN PALLIATION OF MALIGNANT ANASTOMOTIC STRICTURES: A SINGLE CENTER EXPERIENCE
2015
Background: self-expandable metallic stents (SEMS) are employed as the preferred non surgical palliative treatment for gastric outlet obstruction due to malignancies. Metallic stents are often employed to treat malignant anastomotic obstructions after surgicsl interventions as esophagojejunostomy, gastrojejunostomy and esophagogastrojejunostomy. Methods: this case series reports prospectively the clinical outcomes of SEMS in the palliative care of malignant anastomotic strictures caused by the recurrence gastric cancer follwing gastric surgery as oncological curative treatment, in a series of nine consecutive patients, treated between January 2009 and december 2012 in our center. Results: N…
Is there contextuality in behavioural and social systems?
2015
Most behavioral and social experiments aimed at revealing contextuality are confined to cyclic systems with binary outcomes. In quantum physics, this broad class of systems includes as special cases Klyachko-Can-Binicioglu-Shumovsky-type, Einstein-Podolsky-Rosen-Bell-type, and Suppes-Zanotti-Leggett-Garg-type systems. The theory of contextuality known as Contextuality-by-Default allows one to define and measure contextuality in all such system, even if there are context-dependent errors in measurements, or if something in the contexts directly interacts with the measurements. This makes the theory especially suitable for behavioral and social systems, where direct interactions of "everythin…
ePTFE ‐based biomedical devices: An overview of surgical efficiency
2021
International audience; Polytetrafluoroethylene (PTFE) is a ubiquitous material used for implants and medical devices in general because of its high biocompatibility and inertness: blood vessel, heart, table jawbone, nose, eyes, or abdominal wall can benefit from its properties in case of disease or injury. Its expanded version, ePTFE is an improved version of PTFE with better mechanical properties, which extends its medical applications. A material as frequently used as ePTFE with these exceptional properties deserves a review of its main uses, developments, and possibility of improvements. In this systematic review, we examined clinical trials related to ePTFE-based medical devices from t…
Hackmanite—The Natural Glow-in-the-Dark Material
2020
“Glow-in-the-dark” materials are known to practically everyone who has ever traveled by airplane or cruise ship, since they are commonly used for self-lit emergency exit signs. The green afterglow, persistent luminescence (PeL), is obtained from divalent europium doped to a synthetic strontium aluminate, but there are also some natural minerals capable of afterglow. One such mineral is hackmanite, the afterglow of which has never been thoroughly investigated, even if its synthetic versions can compete with some of the best commercially available synthetic PeL materials. Here we combine experimental and computational data to show that the white PeL of natural hackmanite is generated and cont…
