Development and psychometric properties of a self‐report instrument for the assessment of sexual behaviour and concerns of people with mild intellect…
2021
Background: This paper presents a description of the development and psychometric properties of a self-report instrument for the assessment of sexual behaviour and concerns of people with mild intellectual disabilities (SEBECOMID-S). Methods and procedures: The study included 281 people with mild intellectual disabilities. The psychometric properties were examined through exploratory factorial analysis, descriptive statistics, and reliability indices. Results: The exploratory factor analyses offered a structure with three factors: concern about the appropriateness of their sexual behaviour, sexual practices performed, and safe sex practices. The model presents an excellent fit (χ2 /df = 1.1…
Neuropsychological status of alcohol-dependent patients: increased performance through goal-setting instructions.
2004
Aims: The effects of goal-setting instructions on neuropsychological performance of alcohol-dependent patients and control subjects were assessed. Methods: 57 alcohol-dependent patients and 59 carefully age- and education-matched healthy control subjects underwent standard neuropsychological investigation. In addition, the goal-setting paradigm was used to systematically manipulate motivation. Participants were requested to calculate simple mathematical problems repeatedly within phases of a 2-min duration receiving normal or goal setting-instructions (to increase performance in the next phase by 20%). Results: The patients demonstrated deficits in standard neuropsychological tests. Patient…
Auditory temporal processing in schizophrenia: high level rather than low level deficits?
2006
INTRODUCTION: Patients with schizophrenia demonstrate a wide range of information processing deficits. Most recent studies argue in favour of high level deficits, including attention and context processing, whereas fewer studies have demonstrated deficits at earlier stages of processing, such as perceptual discrimination and organisation. This is the first study to investigate both high and low level processing, within a single paradigm, in the case of auditory temporal processing in schizophrenia. METHODS: Patients with schizophrenia were compared to controls on a series of tasks involving three auditory temporal processes varying from low to higher level: (1) segregation of a complex sequ…
Disturbed structural connectivity in schizophrenia primary factor in pathology or epiphenomenon?
2007
Indirect evidence for disturbed structural connectivity of subcortical fiber tracts in schizophrenia has been obtained from functional neuroimaging and electrophysiologic studies. During the past few years, new structural imaging methods have become available. Diffusion tensor imaging and magnetization transfer imaging (MTI) have been used to investigate directly whether fiber tract abnormalities are indeed present in schizophrenia. To date, findings are inconsistent that may express problems related to methodological issues and sample size. Also, pathological processes detectable with these new techniques are not yet well understood. Nevertheless, with growing evidence of disturbed structu…
Characterizing the Theory of Mind Network in Schizophrenia Reveals a Sparser Network Structure
2021
AbstractImpaired social functioning is a hallmark of schizophrenia and altered functional integration between distant brain regions are expected to account for signs and symptoms of the disorder. The functional neuroarchitecture of a network relevant for social functioning, the mentalizing network, is however poorly understood. In this study we examined dysfunctions of the mentalizing network in patients with schizophrenia compared to healthy controls via dynamic causal modelling and an interactive social decision-making game. Network characteristics were analyzed on a single subject basis whereas graph theoretic metrics such as in-degree, out-degree and edge-connectivity per network node w…
Manipulating feedback on schizophrenia: Evidence from a Posner task.
2021
Abstract Individuals with schizophrenia show difficulties in achieving vital objectives. Abnormal behavioral and emotional responses to environmental feedback may be some of the psychological mechanisms underlying this lack of goal attainment in schizophrenia. The present study aims to assess how different types of feedback may affect performance in a computerized affective Posner task (non-monetary vs. monetary rewards; contingent vs. non-contingent feedback). The sample was composed of 32 patients with schizophrenia and 35 controls. Reaction times and error rates were the behavioral measurements. The emotional experience was assessed through self-reported affective scales. The results ind…
Privacy Preserving Client/Vertical-Servers Classification
2019
We present a novel client/vertical-servers architecture for hybrid multi-party classification problem. The model consists of clients whose attributes are distributed on multiple servers and remain secret during training and testing. Our solution builds privacy-preserving random forests and completes them with a special private set intersection protocol that provides a central commodity server with anonymous conditional statistics. Subsequently, the private set intersection protocol can be used to privately classify the queries of new clients using the commodity server’s statistics. The proviso is that the commodity server must not collude with other parties. In cases where this restriction …
Subsequent full publication of abstracts presented in the annual meetings of the Spanish Society of Cardiology.
2013
Abstract Introduction and objectives The Spanish Society of Cardiology holds an annual national meeting with a large number of presentations but the number of full-text publications resulting from these presentations and the journals accepting these manuscripts is unknown. This study aimed to identify the full-text publication rate of accepted abstracts and to analyze the bibliometric features of subsequent publications. Methods We randomly selected a sample of 300 oral presentations at the meetings of the Spanish Society of Cardiology in 2002, 2005 and 2008. Subsequent publications were identified through the Science Citation Index-Expanded, Scopus, Indice Medico Espanol , and Indice Bibli…
Development and evaluation of 3-dimensional printed models of the human tracheobronchial system for training in flexible bronchoscopy.
2017
OBJECTIVES Training and assessment of proper skills in flexible bronchoscopy are major educational goals for cardiothoracic residents. Therefore, we developed 3-dimensional (3D) printed models of the human tracheobronchial system for training and assessment of cardiothoracic residents in flexible bronchoscopy. METHODS Three models of normal (size/shape) human tracheobronchial anatomy were generated using a commercially available 3D printer. Ten residents (inexperienced: Group 1; experienced: Group 2) participated in this study with an experimental setting of initial assessment (Model 1), training (15 min, Model 2) and post-training assessment (Model 3). The time needed for flexible bronchos…
Rhinomanometry: point of care test (POCT) for allergic rhinitis in children?
2021
Allergic rhinitis (AR) is a global health problem: its prevalence is 23% in Europe, although it is underestimated because as many as 45% of the cases remain undiagnosed. Globally, almost 500 million people suffer from AR, which shows its increasing incidences. The diagnostic course of AR is based on clinical history, supported by anterior rhinoscopy. This inspects the anterior part of the nasal cavity accompanied by allergic sensitivity tests (cutaneous allergic skin tests or specific immunoglobulin E levels). The availability of standardised diagnostic proceduresis able to provide objective evaluations of inflammatory situation, and the degree of nasal obstruction may give an advantage in …
