Biomechanical implications of excessive endograft protrusion into the aortic arch after thoracic endovascular repair
2015
Endografts placed in the aorta for thoracic endovascular aortic repair (TEVAR) may determine malappositioning to the lesser curvature of the aortic wall, thus resulting in a devastating complication known as endograft collapse. This premature device failure commonly occurs in young individuals after TEVAR for traumatic aortic injuries as a result of applications outside the physical conditions for which the endograft was designed. In this study, an experimentally-calibrated fluid-structure interaction (FSI) model was developed to assess the hemodynamic and stress/strain distributions acting on the excessive protrusion extension (PE) of endografts deployed in four young patients underwent TE…
Tracheal Ceramic Rings for Tracheomalacia: A Review After 17 Years
2007
Background: Despite different support techniques, the surgical management of tracheomalacia is still a challenging problem. Satisfactory results after internal stenting are above 80%, whereas, when performing external stenting using biocompatible ceramic rings, results are reported at over 90%. Objective: The purpose of this study was to examine the efficiency of surgical treatment in patients with segmentary tracheomalacia using external ceramic ring grafts. Methods: In this retrospective study, we collected data from 12 patients who underwent surgery during the last 17 years for symptomatic segmentary tracheomalacia by use of biocompatible aluminum-oxide ceramic rings. All except one pati…
Yes, you can? A speaker’s potency to act upon his words orchestrates early neural responses to message-level meaning
2013
Evidence is accruing that, in comprehending language, the human brain rapidly integrates a wealth of information sources-including the reader or hearer's knowledge about the world and even his/her current mood. However, little is known to date about how language processing in the brain is affected by the hearer's knowledge about the speaker. Here, we investigated the impact of social attributions to the speaker by measuring event-related brain potentials while participants watched videos of three speakers uttering true or false statements pertaining to politics or general knowledge: a top political decision maker (the German Federal Minister of Finance at the time of the experiment), a well…
Early outcome after implantation of Absorb bioresorbable drug-eluting scaffolds in patients with acute coronary syndromes
2013
The safety of BVS implantation in patients with a high risk for early thrombotic complications has not been studied. We report on the outcomes of patients with acute coronary syndromes (ACS) treated with bioresorbable, everolimus-eluting, vascular scaffolds (BVS).150 consecutive patients with ACS (194 lesions) treated with BVS between May 2012 and July 2013 were compared with a control group composed of 103 consecutive patients (129 lesions) who underwent everolimus drug-eluting stent (DES) implantation in the same time period. The incidence of major adverse cardiac events (MACE: death, non-fatal myocardial infarction, or reintervention) before discharge, at one month and six months was eva…
Experiences of Living in a Disrupted Situation as Partner to a Man With Testicular Cancer
2009
New knowledge has been gained about how close relatives reorient themselves and handle their life situation when facing close relatives' illness. The aim of this study was to describe and elucidate narrated experiences of living in a disrupted situation as partner to a patient with testicular cancer. A qualitative single-case design with a conversational interview using a semistructured guide with open-ended questions was implemented. A young woman whose partner had testicular cancer with metastases was interviewed. Narrative analysis of the data with focus on corporeality, spatiality, temporality, and communality revealed three themes that reflected the woman's concerns in different exist…
Meaning in life moderates hopelessness, suicide ideation, and borderline psychopathology in participants with eating disorders: A longitudinal study
2020
Participants with eating disorders (EDs) experience identity problems, hopelessness, and suicide ideation. Research has confirmed the link between the experience of low meaning in life (MIL) and psychopathology. However, there is a lack of research focusing on MIL in ED. Objectives The objectives of this study are as follows: (a) to analyze whether MIL at baseline moderates the association between ED psychopathology at baseline and borderline symptoms, hopelessness, and suicide ideation at follow-up and (b) to analyze whether MIL moderates the association between suicide ideation, hopelessness, and borderline symptoms at baseline and at the 7-month follow-up. Method The sample was composed …
Vertebro-Basilar Junction Aneurysms: A Single Centre Experience and Meta-Analysis of Endovascular Treatments
2014
Vascular lesions of the vertebrobasilar junction (VBJ) are challenging in neurosurgical practice, and their gold-standard therapy is still under debate. We describe the operative strategies currently in use for the management of these complex vascular lesions and discuss their rationale in a literature meta-analysis and single centre blinded retrospective study. The single centre study included a review of initial presentation, angiographic features and clinical outcome (with modified Rankin Scale [mRS] scores) over a long-term follow-up. In our series, small aneurysms were effectively treated by endosaccular coil embolization, whereas a strategy including flow-diverter devices combined wi…
Surgical treatment of choanal atresia with transnasal endoscopic approach with stentless single side-hinged flap technique: 5 year retrospective anal…
2017
Introdução: A atresia de coanas é uma malformação congênita rara da cavidade nasal caracterizada pela obliteração completa da coana posterior. Nos 67% dos casos a atresia coanal é unilateral, acometendo principalmente (71%) a cavidade nasal direita. Diferentemente da forma unilateral, a atresia coanal bilateral é uma condição com risco de vida, frequentemente associada a angústia respiratória com alimentação e cianose intermitente exacerbada pelo choro. O tratamento cirúrgico permanece como a única opção terapêutica. Objetivo: Relatar a nossa experiência no uso de uma abordagem endoscópica transnasal com a técnica de retalho articulado de um lado só sem colocação de stent para o tratamento …
Comparing extracorporeal shock wave lithotripsy and ureteroscopy laser lithotripsy for treatment of urinary stones smaller than 2 cm: a cost-utility …
2021
[EN] Purpose To analyze the efficiency and cost-utility profile of ureteroscopy versus shock wave lithotripsy for treatment of reno-ureteral stones smaller than 2 cm. Methods Patients treated for urinary stones smaller than 2 cm were included in this study (n = 750) and divided into two groups based on technique of treatment. To assess the cost-utility profile a sample of 48 patients (50% of each group) was evaluated. Quality of life survey (Euroqol 5QD-3L) before-after treatment was applied, Markov model was designed to calculate quality of life in each status of the patients (stone or stone-free with and without double-J stent) and to estimate the incremental cost-utility. Monte carlo sim…
The Path of Cicely Saunders: The “Peculiar Beauty” of Palliative Care
2019
This paper is aimed at focusing on the writings and the experience of the Hospice movement Founder, Dame Cicely Saunders. The in-depth analysis carried out had the objective of verifying if “the way” of Cicely to understand, live and propose palliative care was still current and “beautiful”, so that we can nowadays refer to her fascinating “Original Palliative Care”. With “beauty” we mean, on the one hand, a way able to allow a personal path of research of the meaning of the disease and of the care, both for those who care and for those who are cared for. On the other hand, it seems to us that Cicely strongly suggests how this path can not be carried out alone, but is only possible within …
