High Lipid Content of Prey Fish and n−3 PUFA Peroxidation Impair the Thiamine Status of Feeding-Migrating Atlantic Salmon (Salmo salar) and Is Reflec…
2022
Signs of impaired thiamine (vitamin B1) status in feeding-migrating Atlantic salmon (Salmo salar) were studied in three Baltic Sea areas, which differ in the proportion and nutritional composition of prey fish sprat (Sprattus sprattus) and herring (Clupea harengus). The concentration of n−3 polyunsaturated fatty acids (n−3 PUFAs) increased in salmon with dietary lipids and n−3 PUFAs, and the hepatic peroxidation product malondialdehyde (MDA) concentration increased exponentially with increasing n−3 PUFA and docosahexaenoic acid (DHA, 22:6n−3) concentration, whereas hepatic total thiamine concentration, a sensitive indicator of thiamine status, decreased with th…
¿Es necesaria la quimio-radioterapia preoperatoria en todos los pacientes con cáncer del recto localmente avanzado? Análisis de una serie consecutiva…
2013
Antecedentes: actualmente la quimio-radioterapia preoperatoria es el método estándar de tratamiento de los pacientes con cáncer del recto localmente avanzado. Sin embargo, a partir de la estandarización de la técnica de la escisión total del mesorrecto, las recidivas locales se han reducido significativamente y algunos pacientes podrían evitar el sobretratamiento con quimio-radioterapia preoperatoria y su potencial efecto tóxico. El presente estudio ha sido diseñado con el objetivo de evaluar los factores predictivos de recidiva en una serie institucional de pacientes con cáncer rectal estadificado preoperatoriamente con ecografía rectal y/o resonancia magnética como cT2N+ o cT3 y tratados …

Dual lumen microcatheters for recanalisation of chronic total occlusions: A EuroCTO Club expert panel report
2021
Dual lumen microcatheters (DLMC) have become indispensable tools in the setting of percutaneous coronary intervention (PCI) of chronic total occlusion (CTO). Other than allowing preservation and treatment of bifurcated coronary branches within or in the proximity of the CTO-body, they enable the use of modified parallel wiring, antegrade dissection and re-entry, collateral selection and retrograde negotiation of the distal CTO-cap. This Euro-CTO consensus document describes current DLMCs and suggests a practical guide to anatomies and techniques in which these devices are applicable.
Towards the Point of Care and Noninvasive Classification of Bladder Cancer from Urine Sediment Infrared Spectroscopy. Spectral differentiation of nor…
2021
Abstract Bladder cancer (BC) is the 9th cancer cause of death and one of most cost-intensive in the world. The diagnostic tools are still not at all satisfactory. Herein we evaluated the potential of infrared spectroscopy to detect molecular changes that precede and accompany the carcinogenesis in voided urine sediment. We collected 165 samples from patients being diagnosed for BC and measured them with attenuated total reflectance Fourier transformed infrared spectroscopy (ATR FTIR). Samples were primarily divided into three groups according to cytology that indicated the presence of normal, abnormal and cancer cells. ATR FTIR spectra of sediments were analyzed with the use of partial leas…
Coplanar Indirect-Navigated Intraoperative Ultrasound: Matching Un-navigated Probes With Neuronavigation During Neurosurgical Procedures. How We Do I…
2021
BACKGROUND Intraoperative ultrasound (IOUS) is becoming more and more adopted in neurosurgery, since it has been associated to greater extent of resection (EOR) and to gross total resection (GTR) during brain tumor surgery. IOUS main limitations are spatial resolution, width and orientation of the field of view and scan quality, which are operator-dependent. Furthermore, most neurosurgeons are not confident with this technique, which needs a long learning curve in order to identify and interpret anatomic structures. OBJECTIVE To describe an effective procedure to take advantages of both IOUS and neuronavigation in case of lack of a navigated ultrasound system. METHODS We propose a reliable …
Differences in patients and lesion and procedure characteristics depending on the age of the coronary chronic total occlusion
2018
Introduction: Whether duration of chronic total occlusion (CTO) affects lesion and procedural characteristics remains largely unknown. Aim: To investigate whether CTO duration influences lesion characteristics and revascularization success. Material and methods: EuroCTO Registry data on patients who had CTO percutaneous coronary intervention between January 2015 and April 2017 were analyzed. Three groups were created based on occlusion age: 3 to 6 months (n = 1415), 7 to 12 months (n = 973), > 12 months (n = 1656). Results: Patients with greater CTO duration were older (63.0 (56.0–70.0); 63.0 (56.0–71.0); 66.0 (59.0–73.0) years respectively; p < 0.001), had more 3-vessel disease (32.2…
Update in the Percutaneous Management of Coronary Chronic Total Occlusions
2018
Percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) has been rapidly evolving during recent years. With improvement in equipment and techniques, high success rates can be achieved at experienced centers, although overall success rates remain low. Prospective, randomized-controlled data regarding optimal use and indications for CTO PCI remain limited. CTO PCI should be performed when the anticipated benefit exceeds the potential risk. New high-quality studies of the clinical outcomes and techniques of CTO PCI are needed, as is the expansion of expert centers and operators that can achieve excellent clinical outcomes in this challenging patient and lesion subgroup. In…
Utility of Intravascular Ultrasound in Percutaneous Revascularization of Chronic Total Occlusions
2016
Intravascular ultrasound has been used for >20 years to guide percutaneous coronary intervention in different subsets of coronary lesions. During the last decade, the interest in percutaneous coronary intervention for chronic total occlusion (CTO) has increased dramatically, leading to high success rates. Failure of guidewire crossing is the most common reason for failed CTO attempts. Certain angiographic features, such as blunt proximal CTO cap, tortuosity, heavy calcification, and lack of visibility of path in the distal vessel, increase procedural difficulty. A better understanding of the behavior of the guidewire within the CTO segment may represent a key issue to achieve successful …
PS01.057: THYROIDECTOMY AND LARYNGO-PHARYNGEAL REFLUX: WHAT’S NEW
2018
Abstract Background ‘Local neck symptoms’ may be related to goiter; a persistence of those symptoms after an uncomplicated total thyroidectomy (TT) might be referred to the laryngo-pharyngeal reflux (LPR). Our previous study found a correlation between goiter and LPR in selected patients with local neck symptoms; the purpose of our current study is to investigate the presence of a laringopharyngitis in patients with goiter, before and after TT, even in the absence of local neck symptoms, assessing whether the presence of LPR may play a role at the outset of the symptomatology. Methods Two groups of patients were considered and they differred for the presence or absence of local neck symptom…
