Systematic review with radiomics quality score of cholangiocarcinoma: an EuSoMII Radiomics Auditing Group Initiative
2023
Abstract Objectives To systematically review current research applications of radiomics in patients with cholangiocarcinoma and to assess the quality of CT and MRI radiomics studies. Methods A systematic search was conducted on PubMed/Medline, Web of Science, and Scopus databases to identify original studies assessing radiomics of cholangiocarcinoma on CT and/or MRI. Three readers with different experience levels independently assessed quality of the studies using the radiomics quality score (RQS). Subgroup analyses were performed according to journal type, year of publication, quartile and impact factor (from the Journal Citation Report database), type of cholangiocarcinoma, imaging modali…
The Short-Access Mother–Baby-(SAMBA) Cholangioscopy System
2014
Conventional mother–baby cholangioscopy systems have significant limitations including poor image resolution, limited maneuverability and fragile cholangioscopes. We propose the novel short-access mother–baby-(SAMBA) cholangioscopy system that involves a very short and flexible cholangioscope that is introduced in a dedicated mother duodenoscope with an extra distal side port. Clinical feasibility of this device is demonstrated in three complex cases with cholangiopathies. The strengths of SAMBA cholangioscopy are improved imaging quality and excellent maneuverability of the baby that allows access of small intrahepatic ducts. Evaluation of suspected intrahepatic biliary disease is an excel…
Simultaneous analysis of lysine, Nɛ-carboxymethyllysine and lysinoalanine from proteins
2007
Protein quality was assayed by simultaneous measurement of lysine (Lys), carboxymethyllysine (CML) and lysinoalanine (LAL). GC-FID analysis of N-tert-butyl dimethylsilyl (tBDMSi) derivatives of these amino acids was undertaken. tBDMSi derivates were separated on a CP-SIL 5CB commercially fused silica capillary column (25 m × 0.25 mm i.d., 0.25 μm film thickness) employing a thermal gradient programmed from 200 to 300 °C. The identity of tBDMSi derivatives of Lys, CML and LAL was established by GC–MS while FID detection was employed for quantification. Analytical parameters such as linearity (lysine 350–4200 μM, LAL 3–81 μM, CML 16–172 μM), precision (1–13% variation coefficients), accuracy …
Comparison of different removal techniques for selected pharmaceuticals
2015
[EN] Recently, there is an emergence of endocrine-disrupting compounds, pharmaceuticals, and personal care products (EDC/PPCPs) as important pollutants to remove from drinking water and reclaimed wastewater. In this work, the efficiency of removing pharmaceuticals (PCs) from model aqueous solutions and raw wastewater with ultrafiltration (UF), nanofiltration (NF), activated carbon adsorption (AC), biological methods (SBR) and oxidation with ClO2 was investigated. Some treatments have also been used as combined processes: UF + NF, UF +AC, SBR + ClO2. Ibuprofen, Acetaminophen, Diclofenac, Sulfamethoxazole, Clonazepam, and Diazepam were selected as model compounds. In order to evaluate their r…
Isolating the climate change impacts on air pollution-related-pathologies over Europe – A modelling approach on cases and costs
2019
Air pollution has important implications on human health and associated external costs to society, and is closely related to climate change. This contribution tries to assess the impacts of present (1996–2015) and future (2071–2100 under RCP8.5) air pollution on several cardiovascular and respiratory pathologies and to estimate the difference in the costs associated to those health impacts on European population. For that, air quality data from the WRF-Chem regional chemistry/climate modelling system is used, together with some epidemiological information from the European Commission. The methodology considered relies on the EVA exposure-response functions and economic valuation…

Effects of sleep apnea and kidney dysfunction on objective sleep quality in nondialyzed patients with chronic kidney disease: an ESADA study
2020
Study Objectives: Patients with chronic kidney disease (CKD) often report poor sleep quality, but they commonly exhibit OSA. The aim of this study was to evaluate the influence of OSA severity and of estimated glomerular filtration rate impairment on objective sleep quality in nondialyzed patients with CKD, defined as an estimated glomerular filtration rate <60 mL/min/1.73m2. Methods: Polysomnographic sleep characteristics were compared between patients with (n = 430) and without CKD (n = 6,639) in the European Sleep Apnea Database cohort. Comparisons were repeated in 375 patients with CKD and 375 control patients without CKD matched for sleep center, age, sex, and AHI, and in 310 matche…
Assessment of health-related quality of life of chronic hepatitis C patients in Latvia
2019
Šā pētījuma mērķis ir novērtēt hroniska C hepatīta pacientu ar veselību saistīto dzīves kvalitāti Latvijā, izmantojot anketu par aknu slimībām, un izpētīt jomas, kurās visbiežāk ir traucēta ar veselību saistītā dzīves kvalitāte. Šajā pētījumā tiks arī apskatīti faktori, kas saistīti ar hroniska C hepatīta pacientu dzīves kvalitāti. Šis ir prospektīvs novērojumu pētījums. Hronisko aknu slimību anketa tika pielāgota un izsniegta Latvijas Infektoloģijas centra pacientiem, kam ir seroloģiski apstiprināts hronisks C vīrushepatīts. Kontroles grupā tika iekļauti pieauguši latvieši, kuriem nav diagnosticēts hronisks C vīrushepatīts Pētījuma tika iekļauti 80 pacienti vecumā no 25 līdz 78 gadiem (vid…
Transparency in two municipalities of great population of the Valencian Community: between mimetic isomorphism and the generation of legitimity
2020
Este trabajo de investigación tiene como objetivo fundamental la realización de un análisis sobre los elementos que han justificado la calidad de los procesos de asunción de la transparencia en los ayuntamientos de Alicante y València (2008-2017). En concreto, se partirá del neo-institucionalismo sociológico y de los índices de Transparencia Internacional para caracterizar esta herramienta de buen gobierno y la importancia relativa en ambos ayuntamientos. Entre algunos de los resultados preliminares que hemos obtenido, podemos destacar tanto el papel isomórfico de la legislación como la necesidad de mejorar la reputación de las instituciones estudiadas para implementar dichas políticas. The…
Policies can help to apply successful strategies to control soil and water losses. The case of chipped pruned branches (CPB) in Mediterranean citrus …
2018
[EN] There is a need to devise management strategies that control soil and water losses in agriculture land to allow the design of proper policies to achieve sustainability. It is the responsibility of scientists to work with other actors to co-construct strategies that will lead to sustainable land-use policies. Using chipped pruned branches (CPB) as mulch can be a viable option because they represent local (in situ) organic material that can restore soil nutrient and organic matter. This research assesses: i) the perception of farmers towards different types of management strategies and CPB's costs; ii) the biomass yield of citrus branches and the impact of CPB on soil properties; iii) ho…
