Joint use of cardio-embolic and bleeding risk scores in elderly patients with atrial fibrillation
2013
Background Scores for cardio-embolic and bleeding risk in patients with atrial fibrillation are described in the literature. However, it is not clear how they co-classify elderly patients with multimorbidity, nor whether and how they affect the physician's decision on thromboprophylaxis. Methods Four scores for cardio-embolic and bleeding risks were retrospectively calculated for ⥠65 year old patients with atrial fibrillation enrolled in the REPOSI registry. The co-classification of patients according to risk categories based on different score combinations was described and the relationship between risk categories tested. The association between the antithrombotic therapy received and t…
Élites di governo e «mastre» ad Agrigento fra Trecento e Quattrocento
2002
ITALIANO: Sebbene le comunità demaniali siciliane acquisiscano un peso centrale ed inedito nei regni di Martino e di Alfonso V, a parte poche eccezioni mancano ricerche monografiche e comparate delle dinamiche sociali cittadine. Questo articolo prende in esame la città di Agrigento, in particolare la formazione dei raggruppamenti sociali, il loro differente ruolo politico e gli equilibri di potere tra i gruppi di governo, con riferimento alle istituzioni delle liste di eleggibili per l'elezione alle cariche locali. È opinione comune che le istituzioni di tali liste rappresentino l'affermazione della aristocrazia, sugli altri raggruppamenti sociali, nelle dinamiche urbane sin dalla seconda m…
Relationship satisfaction can help to maintain the positive effect of childbirth on parental self-esteem
2020
The transition to parenthood is accompanied by declined self-esteem levels, which may be explained by parents’ relationship satisfaction. However, prior research examined self-esteem only shortly before and after childbirth and had no or only unmatched childless respondents as a control group, limiting the possibility to examine long-term adaptive processes and the causal interpretation of the associations. Thus, we used panel data (10 years, 4,075 individuals, and 16,122 observations) to compare self-esteem and relationship satisfaction trajectories of parents with matched childless respondents using propensity score matching. We found a quadratic trajectory for parents’ self-esteem, whic…
Troponin I and cardiovascular risk prediction in the general population: the BiomarCaRE consortium
2016
AIMS: Our aims were to evaluate the distribution of troponin I concentrations in population cohorts across Europe, to characterize the association with cardiovascular outcomes, to determine the predictive value beyond the variables used in the ESC SCORE, to test a potentially clinically relevant cut-off value, and to evaluate the improved eligibility for statin therapy based on elevated troponin I concentrations retrospectively.METHODS AND RESULTS: Based on the Biomarkers for Cardiovascular Risk Assessment in Europe (BiomarCaRE) project, we analysed individual level data from 10 prospective population-based studies including 74 738 participants. We investigated the value of adding troponin …
DFT and experimental studies on structure and spectroscopic parameters of 3,6-diiodo-9-ethyl-9H-carbazole
2015
The first report on crystal and molecular structure of 3,6-diiodo-9-ethyl-9H-carbazole is presented. Experimental room-temperature X-ray and 13C chemical shift studies were supported by advanced theoretical calculations using density functional theory (DFT). The 13C nuclear magnetic shieldings were predicted at the non-relativistic and relativistic level of theory using the zeroth-order regular approximation (ZORA). Theoretical relativistic calculations of chemical shifts of carbons C3 and C6, directly bonded to iodine atoms, produced a reasonable agreement with experiment (initial deviation from experiment of 44.3 dropped to 4.25 ppm). The changes in ring aromatic character via simple harm…
Molecular modeling and experimental studies on structure and NMR parameters of 9-benzyl-3,6-diiodo-9H-carbazole
2015
A combined experimental and theoretical study has been performed on 9-benzyl-3,6-diiodo-9H-carbazole. Experimental X-ray (100.0 K) and room-temperature 13C NMR studies were supported by advanced density functional theory (DFT) calculations. The non relativistic structure optimization was performed and the 13C nuclear magnetic shieldings were predicted at the relativistic level of theory using the Zeroth Order Regular Approximation (ZORA). The changes in the benzene and pyrrole rings compared to the unsubstituted carbazole or the parent molecules were discussed in terms of aromaticity changes using the harmonic oscillator model of aromaticity (HOMA) and the nucleus independent chemical shift…
Epidemiology and Reporting Characteristics of Systematic Reviews of Biomedical Research: A Cross-Sectional Study.
2016
Background Systematic reviews (SRs) can help decision makers interpret the deluge of published biomedical literature. However, a SR may be of limited use if the methods used to conduct the SR are flawed, and reporting of the SR is incomplete. To our knowledge, since 2004 there has been no cross-sectional study of the prevalence, focus, and completeness of reporting of SRs across different specialties. Therefore, the aim of our study was to investigate the epidemiological and reporting characteristics of a more recent cross-section of SRs. Methods and Findings We searched MEDLINE to identify potentially eligible SRs indexed during the month of February 2014. Citations were screened using pre…
Positioning of the cross-stitch on the modified Kessler core tendon suture
2018
[EN] Cryopreserved human tendons were sutured with different variations of a modified Kessler-type grasping suture in a series of different designs in order to assess the influence of the distance between the cross-stitch on the core suture (5 and 10 mm from the cut tendon edge) on the peripheral suture. An original mathematical model was employed to explain the mechanical behavior (strength, deformation, and distribution of load) of the different suture designs. The effect of the peripheral epitendinous suture, combined with the distance of the core suture, was evaluated. The variation of core suture distance had no relevant consequences on the overall resilience of the design. However, in…
El alcance de la responsabilidad solidaria prevista en el artículo 42 ET
2020
El artículo 42 ET impone sobre el empresario que contrata o subcontrata con otros la realización de obras o servicios pertenecientes a su propia actividad una responsabilidad solidaria sobre ciertas obligaciones contraídas por el contratista y el subcontratista con sus trabajadores, siempre que hayan nacido durante la vigencia de la contrata. En principio, el significado de la previsión normativa se presenta como relativamente sencillo; no obstante, su aplicación práctica suscita diferentes dudas interpretativas. Pues bien, el objeto de este trabajo se dirige a perfilar el contorno y contenido de la responsabilidad solidaria recogida en el art. 42 ET, lo que exige delimitar con claridad su …
