Hyvinvointi-, hius- ja kauneusalan ammatteihin opiskelevat kriittisinä nettilukijoina
2023
Tutkimuksessa selvitettiin ammatillisen koulutuksen opiskelijoiden (hyvinvointi-, hius- ja kauneusala) kriittistä nettilukutaitoa. Lisäksi tarkasteltiin aikaisemman tiedon, tekstien lukemisjärjestyksen ja perustelutaitojen yhteyttä siihen, kuinka hyvin opiskelijat osasivat arvioida luotettavia (varmentaminen) ja epäluotettavia (kyseenalaistaminen) nettitekstejä sekä erottaa luotettavat tekstit epäluotettavista. Tutkimukseen osallistui 82 opiskelijaa, joista valtaosa oli 15–18-vuotiaita. Opiskelijat lukivat ja arvioivat kaksi luotettavaa ja kaksi epäluotettavaa tekstiä sokerin vaikutuksista. Opiskelijat arvioivat kirjoittajan asiantuntijuutta, tarkoitusperiä, julkaisupaikkaa ja evidenssin la…
Predilation technique with balloon angioplasty to facilitate percutaneous groin access of large size sheath through scar tissue
2017
Purpose Percutaneous remote access for endovascular aortic repair is an advantageous alternative to open access. Previous surgery in the femoral region and the presence of synthetic vascular grafts in the femoral/iliac arteries represent major limitations to percutaneous remote access. The aim of this study was to evaluate an original technique used for enabling percutaneous remote access for thoracic or abdominal endovascular aortic repair in patients with scar tissue and/or a vascular graft in the groin. Methods Twenty-five consecutive patients with a thoracic (11/25; 44%) or an aortic aneurysm (14/25; 66%) and with a synthetic vascular graft in the groin (16/25; 64%) or a redo groin acce…
A clampless and sutureless aortic anastomosis technique using an endograft connector for aortoiliac occlusive disease in which the aorta cannot be cl…
2012
Bypass surgery in aortoiliac or aortofemoral occlusive disease can be technically demanding and hazardous due to huge calcifications and/or patient co-morbidities. We report about mid-term results of a telescoping sutureless aortic anastomosis technique using endografts as connectors to address such challenging situations. This is a single-center experience (2004–2011) in seven patients (63 ± 6 years) requiring aortoiliac (three) or aortofemoral (four) bypass surgery. In six cases, an aortic stent graft was telescoped into the infrarenal aorta and partly deployed within the aorta and partly outside the aorta. In the first case, a bifurcated stent graft was deployed and the iliac legs were …
Endoluminal Stent-Graft Relining of Visceral Artery Bypass Grafts to Treat Perigraft Seroma
2013
PURPOSE: To describe the endovascular treatment of intra-abdominal perigraft seromas associated with small-caliber expanded polytetrafluoroethylene (ePTFE) grafts. CASE REPORTS: Two patients who underwent hybrid repair of thoracoabdominal aortic aneurysms in which renovisceral bypass grafts were implanted presented with large, symptomatic perigraft seromas. The 5- to 8-mm-diameter ePTFE bypass grafts believed to be involved in the seromas were successfully relined with self-expanding Viabahn stent-grafts in percutaneous procedures. The patients' symptoms were relieved, and imaging follow-up (18 and 10 months, respectively) has shown near complete resorption of the seromas. CONCLUSION: It is…
Chimney and periscope grafts observed over 2 years after their use to revascularize 169 renovisceral branches in 77 patients with complex aortic aneu…
2013
^ ^Purpose: To evaluate the performance of periscope and/or chimney grafts (CPGs) in theendovascular treatment of pararenal or thoracoabdominal aneurysms using off-the-shelfdevices.Methods: Between February 2002 and August 2012, 77 consecutive patients (62 men; meanage 7369 years) suffering from pararenal aortic (n¼55), thoracoabdominal (n¼16), or arch tovisceral artery aneurysms (n¼6) were treated with aortic stent-graft implantation requiringchimney and/or periscope grafts to maintain side branch perfusion. CPGs were planned inadvance and were not used as bailout. A standardized follow-up protocol includingcomputed tomographic angiography, laboratory testing, and clinical examination wasp…
Résumé des recherches sur les bioagresseurs du riz pluvial
2009
La recherche a été menée sur plusieurs fronts ces dernières campagnes pour la lutte durable contre les bioagresseurs du riz pluvial. Elle s'est orientée vers l'exploitation de la biodiversité des plantes et la recherche de systèmes de culture pour gérer les " vers blancs " ou " scarabées noirs " (Coleoptera, Scarabaeidae), les foreurs de tiges, la pyriculariose et le striga. Les résultats des essais réalisés avec le projet BVlac sur l'utilisation du champignon entomopathogène Metarhizium anisopliae ainsi que les résultats des essais menés avec l'ONG Tafa sur la lutte contre le striga dans différents systèmes de culture seront présentés par ailleurs. Nous rapporterons ici les recherchés mené…

AGuIX® from bench to bedside-Transfer of an ultrasmall theranostic gadolinium-based nanoparticle to clinical medicine.
2019
International audience; AGuIX® are sub-5 nm nanoparticles made of a polysiloxane matrix and gadolinium chelates. This nanoparticle has been recently accepted in clinical trials in association with radiotherapy. This review will summarize the principal preclinical results that have led to first in man administration. No evidence of toxicity has been observed during regulatory toxicity tests on two animal species (rodents and monkeys). Biodistributions on different animal models have shown passive uptake in tumours due to enhanced permeability and retention effect combined with renal elimination of the nanoparticles after intravenous administration. High radiosensitizing effect has been obser…
Radiomics and artificial intelligence in prostate cancer: new tools for molecular hybrid imaging and theragnostics
2022
AbstractIn prostate cancer (PCa), the use of new radiopharmaceuticals has improved the accuracy of diagnosis and staging, refined surveillance strategies, and introduced specific and personalized radioreceptor therapies. Nuclear medicine, therefore, holds great promise for improving the quality of life of PCa patients, through managing and processing a vast amount of molecular imaging data and beyond, using a multi-omics approach and improving patients’ risk-stratification for tailored medicine. Artificial intelligence (AI) and radiomics may allow clinicians to improve the overall efficiency and accuracy of using these “big data” in both the diagnostic and theragnostic field: from technical…
Classification of Chimney EVAR-Related Endoleaks: Insights from the PERICLES Registry
2017
Juxtarenal aortic aneurysms (JAAs) pose significant challenges for endovascular aneurysm repair (EVAR). A short or absent infrarenal neck typically excludes standard EVAR as a viable or reasonable treatment option. In this context, the use of chimney grafts (chEVAR) is gaining in popularity and applicability. These grafts are designed to course in the aortic lumen outside the main stent-graft to maintain normal perfusion to the involved target branches. As such, they may represent a promising and less resource-intensive option for management of JAAs. However, this technical strategy is not without challenges of its own, particularly the inevitable creation of “gutters” that result from the …
