Treatment of isolated ascending aortic aneurysm by off-pump epiaortic wrapping is safe and durable.
2016
OBJECTIVES: Isolated ascending aortic aneurysm (iAA) is usually treated by open graft repair requiring sternotomy, cardiopulmonary bypass (CPB) and cardioplegia. This approach carries significant mortality in older patients or those presenting with comorbidities. We report an original series of patients presenting with iAA and treated with epiaortic wrapping by using a synthetic mesh. This less invasive aortic repair technique allows reducing the aortic diameter to a predefined value and is performed without CPB. METHODS: Data from patients presenting with an iAA and treated with the wrapping technique (WT) by polypropylene/polyester mesh from November 2006 to July 2015 were collected. The …
Value and limitations of transesophageal echocardiography in the evaluation of aortic prostheses.
1993
Results of 34 transesophageal (TEE) studies in patients with suspected aortic prosthetic dysfunction were compared with transthoracic echocardiographic (TTE) results and to anatomic findings. Mass lesions noted at surgery (autopsy) were correctly described in 93% by TEE versus 43% by TTE. Abscesses were detected in 88% by TEE versus 18% by TTE. Bioprosthetic degeneration was visualized in 88% versus 38% and prosthetic obstruction correctly identified in 75% versus 50% by TEE and TTE, respectively. Anatomic aortic regurgitant lesions were identified in 96% by TEE versus 77% by TTE, whereas the correct origin was detected in 88% of cases by TEE versus 54% of cases by TTE. TEE provides valuabl…
Incidence, Predictive Factors, and Prognostic Impact of Silent Atrial Fibrillation After Transcatheter Aortic Valve Implantation.
2018
New onset atrial fibrillation post-transcatheter aortic valve implantation (TAVI) is common and is associated with adverse outcomes. However, silent atrial fibrillation (AF) is poorly documented in the context. This study sought to evaluate the incidence, predictive factors, and prognostic value of Silent AF post-TAVI. All the consecutive patients with TAVI were prospectively analyzed by continuous electrocardiogram monitoring≥48 hours after implantation. Silent AF was defined as asymptomatic episodes lasting at least 30 seconds. The population was divided into 3 groups: history of AF, no-AF, and silent AF. Among the 206 patients implanted with TAVI, 19 (16.1%) developed silent AF. Compared…
Identifying the Unknown Content of an Ancient Egyptian Sealed Alabaster Vase from Kha and Merit’s Tomb Using Multiple Techniques and Multicomponent S…
2020
This article highlights the multianalytical study of exuded liquid from an ancient Egyptian sealed alabaster vase by Master's students in an applied chemistry for cultural heritage course. Master students are introduced to the field of Archaeometry that see the collaboration of experts in different areas of research such as conservators, curators of museums, physicists, chemists, etc. The sample is a residue exuded on the linen strip sealing an ancient Egyptian alabaster vase (inventory number S.8448) from the collection of the Museo Egizio in Turin (Italy). The students start to plan the noninvasive investigation by X-ray fluorescence (XRF), transmission electron microscopy (TEM), and ener…
Mündliche Kompetenz und Bewusstsein beim unterrichtlichen Fremdsprachenlernen
2014
Das Buch befasst sich mit dem Zusammenspiel von kognitiven, emotionalen und motivationalen Faktoren beim Aufbau von mündlicher Kompetenz in Deutsch als Tertiärsprache bei erwachsenen Italienern. Es stützt sich dabei auf ein interdisziplinäres Vorgehen, das theoretisch erörtert und in seiner Methodenwahl ausführlich dargelegt wird, insbesondere die Videografie sowie intro-/retrospektive Verfahren. Die Ergebnisse der Studie veranschaulichen die Lernprozesse einmal klassenübergreifend, zum anderen erfolgt eine detaillierte Analyse der einzelnen Lernenden. Das Literaturverzeichnis liefert Lehrenden, Studierenden und Forschern eine erschöpfende bibliographische Quelle zu den behandelten Themen.
Archeologia, quale lavoro dopo l’università? Un’analisi multidisciplinare del rapporto tra ricerca, formazione, professione e opportunità imprenditor…
2018
Nel corso degli ultimi venti anni, la ricerca scientifica si è caratterizzata per un approccio multidisciplinare, capace di ripensare le discipline di base, nella convinzione che la contaminazione possa gene- rare nuova conoscenza. In un siffatto con- testo, gli studiosi di archeologia più volte hanno messo in discussione il ruolo della propria disciplina nella società contemporanea, interrogandosi sulle possibili interazioni e sulle sinergie con scienze diverse e apparentemente ‘lontane’. Questa sfida pone non poche problematiche riguardo agli investimenti in capitale umano che sono necessari per far coesistere e sviluppare saperi diversi in modo integrato. Il riferimento è alla definizion…
The Studio: Reflections and Issues Arising
1999
An advanced Telematic Studio was built at the University of Jyvaskyla to combine the latest technologies for local and distributed work and/or meetings. The objectives were to combine leading edge technologies with ethnographic design principles derived from CSCW and HCI to support a broad range of activities. We informed the design by studies of similar facilities on other sites. The Studio is popular, and it is easy to give glowing accounts of its use. Nevertheless, over three years a significant number of problems have arisen with both technologies and uses. Some of these are local. Others may be generalisable to any ‘cooperative building’. For example: problems with videoconferencing; i…
Complement split products and proinflammatory cytokines in intraoperatively salvaged unwashed blood during hip replacement: comparison between hepari…
2008
Background and Objectives The aim of the present study was to investigate the quality of shed blood collected in a new intraoperative autotransfusion system (Sangvia®, AstraTech, Sweden) and to study whether heparin-coated surfaces in the device reduce the production of inflammatory mediators. Material and Methods The study was randomized and prospective. Twelve total hip arthroplasty patients whose blood was collected with a device having a heparin-coated surface and 12 patients whose blood was collected with a device having a non-heparin-coated surface were included. Venous blood was drawn from the patients preoperatively. Intraoperatively 200 ml salvaged blood was collected and samples…
Successful treatment of a patient with ARDS after pneumonectomy using high-frequency oscillatory ventilation.
1999
High frequency oscillatory ventilation (HFOV) was used in a patient who developed the acute respiratory distress syndrome 5 days following a right pneumonectomy for bronchogenic carcinoma. When conventional pressure-controlled ventilation failed to maintain adequate oxygenation, HFOV dramatically improved oxygenation within the first few hours of therapy. Pulmonary function and gas exchange recovered during a 10-day period of HFOV. No negative side effects were observed. Early use of HFOV may be a beneficial ventilation strategy for adults with acute pulmonary failure, even in the postoperative period after lung resection.
Taking part in Nordic collaboration : nursing students' experiences and perceptions from a learning perspective: a qualitative study
2015
BACKGROUND: Nordic networking of different kinds has a long tradition aiming to increase collaboration and understanding between citizens in different countries. Cultural competence in relation to health care and nursing is important for clinical nurses and is a central issue in nurse education. OBJECTIVE: To gain an understanding of what nurse students experienced and learned during an intensive course in diabetes together with students and nurse educators from Denmark, Finland, Iceland, Norway, Sweden and the Faroe Islands. METHODS: In 2012, an intensive course within the Nordic network, Nordkvist, was conducted in Faroe Islands with the theme "Nursing - to live a good life with diabetes"…
