Three-dimensional parametric modeling of bicuspid aortopathy and comparison with computational flow predictions
2016
Bicuspid aortic valve (BAV)-associated ascending aneurysmal aortopathy (namely âbicuspid aortopathyâ) is a heterogeneous disease making surgeon predictions particularly challenging. Computational flow analysis can be used to evaluate the BAV-related hemodynamic disturbances, which likely lead to aneurysm enlargement and progression. However, the anatomic reconstruction process is time consuming so that predicting hemodynamic and structural evolution by computational modeling is unfeasible in routine clinical practice. The aim of the study was to design and develop a parametric program for three-dimensional (3D) representations of aneurysmal aorta and different BAV phenotypes starting fr…
The convergent validity of four indices of congnitive complexity in person perception. A multi-index multimethod and factor analytical approach.
1975
.— An application of the Campbell and Fiske multimethod-multitrait analysis and factor analysis was used to study the convergent validity of the following indices of cognitive complexity: Bieri's Index, Vannoy's Interaction Variance Measure, Number of Factors, and First Factor Percentage. In the analysis the individual constructs elicited by Reptest were contrasted with two sets of provided constructs, namely Semantic Differential and Personality Differential scales. The subjects were 36 psychology students. The results indicated that the convergent validity of the indices over construct type was low and that the construct type had an effect upon the intercorrelations of different indices o…
Free Bipedicled Radial Forearm and Posterior Interosseous Artery Perforator Flap Phalloplasty
2019
Abstract Introduction The free radial forearm (FRFA) flap is universally still considered as the gold standard technique in penile reconstruction. Typically, a considerably large flap is required, often involving almost the entire circumference of the forearm. Partial necrosis may occur at the distal-most (dorsoradial) part of the flap as a result of insufficient perfusion. Aim To describe a new technique using the posterior interosseous artery (PIOA) to supercharge FRFA phalloplasty. Methods In a 12-month period, all patients having FRFA flap phalloplasty were enrolled. Perioperative, after complete flap dissection, an indocyanine green perfusion scan was performed. In case of insufficient…
Canal construction destroys the barrier between major European invasion lineages of the zebra mussel.
2002
Since the mid-1980s the zebra mussel, Dreissena polymorpha, Pallas 1771, has become the protagonist of a spectacular freshwater invasion in North America due to its large economic and biological impact. Several genetic studies on American populations have failed to detect any large-scale geographical patterns. In western Europe, where D. polymorpha has been a classical invader from the Pontocaspian since the early 19th century, the situation is strikingly different. Here, we show with genetic markers that two major western European invasion lineages with lowered genetic variability within and among populations can be discriminated. These two invasion lineages correspond with two separate na…
Pre- and postnatal exposure to tobacco smoke and respiratory outcomes during the first year
2015
The different role of prenatal and postnatal exposure to tobacco smoke in respiratory outcomes in infants has not yet been clearly established. Our objective is to assess the effects of these exposures on the risk of respiratory outcomes during the first year of life of infants from a Spanish multicenter cohort study. A total of 2506 women were monitored until delivery. About 2039 infants made up the final population. The outcomes were caused by the occurrence of the following: otitis, cough persisting for more than 3 weeks, lower respiratory tract symptoms (wheezing or chestiness), and lower respiratory tract infections (bronchitis, bronchiolitis, or pneumonia). The relationship between pr…
The Chronic Psychosocial Stress Paradigm in Male Tree Shrews: Evaluation of a Novel Animal Model for Depressive Disorders
2002
To improve our knowledge of the causal mechanisms of stress-related disorders such as depression, we need animal models that mirror the situation in patients. One promising model is the chronic psychosocial stress paradigm in male tree shrews, which is based on the territorial behaviour of these animals that can be used to establish naturally occurring challenging situations under experimental control in the laboratory. Co-existence of two males in visual and olfactory contact leads to a stable dominant-subordinate relationship, with subordinates showing distinct stress-induced behavioural and neuroendocrine alterations that are comparable to the symptoms observed during episodes of depress…
Personality and Emotional Intelligence in Older Adults: A Predictive Model Based on Structural Equations Modeling
2018
Recent research on emotions in aging points to emotional intelligence (EI) as a factor that plays an important role in this process, and different conceptualizations of EI show that this construct is closely linked to personality in the general population. The main purpose of this study was to find out whether findings obtained in the general population indicating a predictive relationship between personality and EI are also confirmed during the aging process. A sample of 233 healthy older subjects between 60 and 90 years old was used. Participants answered two self-report scales on EI and personality, respectively. Structural equation modeling was used to test the predictive role of person…
Adaptation and validation for Spain of the Child-Oral Impact on Daily Performance (C-OIDP) for use with adolescents.
2010
Objectives. To linguistically and culturally adapt the Child-OIDP, an Oral Health-Related Quality of Life (OHRQoL) index, into Spanish for use among adolescents, and to validate it by evaluating the psychometric properties of the self-administered version. Study design. Following a forward - backward translation procedure, the English version of the questionnaire was translated by independent translators and the reconciled version was then sent to three experts for assessment. A pilot study was conducted on a sub-sample of 30 adolescents aged between 11 - 12 years to assess their understanding of the questionnaire and its wording. The participants in the main study comprised 425 school chil…
Bladder cancer index: cross-cultural adaptation into Spanish and psychometric evaluation.
2014
Background: The Bladder Cancer Index (BCI) is so far the only instrument applicable across all bladder cancer patients, independent of tumor infiltration or treatment applied. We developed a Spanish version of the BCI, and assessed its acceptability and metric properties. Methods: For the adaptation into Spanish we used the forward and back-translation method, expert panels, and cognitive debriefing patient interviews. For the assessment of metric properties we used data from 197 bladder cancer patients from a multi-center prospective study. The Spanish BCI and the SF-36 Health Survey were self-administered before and 12 months after treatment. Reliability was estimated by Cronbach’s alpha.…
Norwegian version of the Nutritional Form for the Elderly: sufficient psychometric properties for performing institutional screening of elderly patie…
2009
The objective of this study was to test if the Norwegian version of the nutritional screening instrument entitled Nutritional Form for the Elderly (NUFFE-NO) demonstrates sufficient evidence of reliability and validity, including sensitivity and specificity, when applied to a select group of elderly hospital patients. The hypothesis was that NUFFE-NO has sufficient psychometric properties to be used as a screening instrument. The model used for the testing procedure was designed to test reliability (homogeneity and stability) and validity (criterion-related, concurrent validity, and construct validity) including sensitivity and specificity in a cross-sectional study. One-hundred fifty-eight…
