Fishery-induced selection for slow somatic growth in European eel
2012
International audience; Both theoretical and experimental studies have shown that fishing mortality can induce adaptive responses in body growth rates of fishes in the opposite direction of natural selection. We compared body growth rates in European eel (Anguilla anguilla) from three Mediterranean stocks subject to different fishing pressure. Results are consistent with the hypotheses that i) fast-growing individuals are more likely to survive until sexual maturity than slow-growing ones under natural conditions (no fishing) and ii) fishing can select for slow-growing individuals by removing fast-growing ones. Although the possibility of human-induced evolution seems remote for a panmictic…
Surgical Treatment of Extravasation Injuries
2005
The authors present their experience of treating anti-cancer drug extravasation by means of a composite surgical technique that consists of infiltration with physiological solution and hyaluronidase and subsequent manual aspiration of solutes alternated with profuse irrigation of the infiltrated area. In the immediate post-op we carry out a medical therapy that consists of calciparine and topic antibiotic and/or steroid creams. Since the year 2000 this technique has been used on 25 patients. We have had neither complications nor scars. Copyright 2005 Wiley-Liss, Inc Surgical treatment of extravasation injuries.

A case of squamocellular uterine cervix carcinoma metastatic to the skin with enterocutaneous fistula.
2006
Metastases to the skin complicated by enterocutaneous fistula are a rare event in gynecological malignancies. We present the case of a 70-year-old woman with uterine cervix carcinoma metastatic to the skin and treated with surgery and radiotherapy. The last relapse to the skin was complicated by the formation of an enterocutaneous fistula. This low-output fistula was treated with surgery and adequate supportive care. The treatment of enterocutaneous fistulas may be either invasive (surgical resection, surgical repair with corrective procedures or with myocutaneous flaps, colonic and/or urinary diversion, endoscopic treatments with metallic stents) or conservative (skin care and local disin…
Multiclass HCV resistance to direct-acting antiviral failure in real-life patients advocates for tailored second-line therapies
2017
Background & Aims: Despite the excellent efficacy of direct-acting antivirals (DAA) reported in clinical trials, virological failures can occur, often associated with the development of resistance-associated substitutions (RASs). This study aimed to characterize the presence of clinically relevant RASs to all classes in real-life DAA failures. Methods: Of the 200 virological failures that were analyzed in 197 DAA-treated patients, 89 with pegylated-interferon+ribavirin (PegIFN+RBV) and 111 without (HCV-1a/1b/1g/2/3/4=58/83/1/6/24/25; 56.8% treatment experienced; 65.5% cirrhotic) were observed. Sanger sequencing of NS3/NS5A/NS5B was performed by home-made protocols, at failure (N= 200) and w…
Efficacy and safety of yttrium 90 ibritumomab tiuxetan in patients with relapsed or refractory diffuse large B-cell lymphoma not appropriate for auto…
2007
A prospective, multicenter, nonrandomized phase 2 trial was conducted to evaluate the efficacy and safety of a single dose of yttrium-90 (90Y) ibritumomab tiuxetan in elderly patients in first relapsed or primary refractory diffuse large B-cell lymphoma (DLBCL) ineligible for stem-cell transplantation. Patients had been previously treated with chemotherapy (group A, n = 76) or chemotherapy plus rituximab (group B, n = 28). Patients in group A were further divided into patients in whom induction therapy had failed (stratum AI, n = 33) and patients who had relapsed after achieving complete response (CR; stratum AII, n = 43). The overall response rate (ORR) was 52% and 53% in strata AI and AII…
Classification of diabetes-related retinal diseases using a deep learning approach in optical coherence tomography
2019
Background and objectives: Spectral Domain Optical Coherence Tomography (SD-OCT) is a volumetric imaging technique that allows measuring patterns between layers such as small amounts of fluid. Since 2012, automatic medical image analysis performance has steadily increased through the use of deep learning models that automatically learn relevant features for specific tasks, instead of designing visual features manually. Nevertheless, providing insights and interpretation of the predictions made by the model is still a challenge. This paper describes a deep learning model able to detect medically interpretable information in relevant images from a volume to classify diabetes-related retinal d…
Supervisor leadership style, employee regulatory focus, and leadership performance: A perspectivism approach
2019
[EN] Drawing on regulatory focus theory, this research proposes that transformational leadership performance depends on followers' circumstances. The analysis of 125 people from two Spanish service firms reveals that, apart from transformational leadership, the presence of academic education, intrinsic job satisfaction and high customer contact, and the absence of family responsibilities, are core conditions for the presence of high leadership performance. The first contribution of this study is the direct inference of follower's regulatory focus from the observation of individuals' circumstances. The second contribution is that leaders should consider followers' circumstances to adopt a su…
