Development of a questionnaire measuring treatment concerns in regular dental patients

2008

–  Objectives:  The aim of this study was to develop an instrument measuring core concerns about dental treatment guided by Reiss’ expectancy theory of fear. This would include the content domains of injury, somatic reaction and interpersonal concerns, to study the underlying factorial structure, and to determine the test quality of the resulting subscales. Methods:  A total of 555 regular dental patients answered the item pool. Subsamples filled in the Dental Anxiety Scale (DAS) (n = 346) and the Anxiety-Present Scale of the state-form of the State-Trait Anxiety Inventory (STAI-S) (n = 187). A second sample (n = 89) was used to determine test-retest reliability and bias for social desirabi…

Mafia and psychopathy.

2014

Background In popular culture, Mafia members are often portrayed as ruthless, callous and remorseless, but there is no empirical research on their personality traits. Aims The goal of this research was to examine levels of psychopathic traits among Mafia members who have been convicted of a criminal offence. Methods The Psychopathy Checklist-Revised (PCL-R) rated 30 Italian adult male prisoners who had been convicted for Mafia-related crimes (86% resident in one 6-month period) and 39 next adjacent convicted men who were not enrolled in any criminal organisation. Results Mafia members obtained lower PCL-R total scores, interpersonal and affective (PCL-R factor 1) scores and lifestyle scores…

Predictors of neurocognitive impairment at 3years after a first episode non-affective psychosis

2013

Abstract Background Neurocognitive impairment is a core component of schizophrenia. However, patients show great variability in the level and course of deficits. The goal of the present longitudinal study was to identify predictors of neurocognitive impairment in first episode psychosis patients. Methods N eurocognitive performance was analyzed in a cohort of 146 patients 3 years after a first episode non-affective psychosis. Subgroups, impaired vs. unimpaired, were compared on baseline clinical, neuropsychological, premorbid and sociodemographic characteristics. Results Fifty-nine percent of participants presented general neurocognitive impairment and regression analyses demonstrated that …

Prediction of acute clinical response following a first episode of non affective psychosis: results of a cohort of 375 patients from the Spanish PAFI…

2013

Abstract Objective Predicting response to antipsychotic treatment might optimize treatment strategies in early phases of schizophrenia. We aimed to investigate sociodemographic, premorbid and clinical predictors of response to antipsychotic treatment after a first episode of non-affective psychosis. Method 375 (216 males) patients with a diagnosis of non affective psychosis entered the study. The main outcome measure was clinical response at 6 weeks and variables at baseline were evaluated as predictors of response. ANOVA for continuous and chi-square for categorical data were used to compare responders and non-responders. Multivariate logistic regression was used to establish a prediction …

Suicidal behaviour in first-episode non-affective psychosis: Specific risk periods and stage-related factors

2014

Suicide is a major cause of premature death in psychosis. Earlier stages have been associated with higher risk. However, such risk periods have not been specifically determined and risk factors for suicidal behaviour may change over those periods, which may have crucial implications for suicide prevention. The aim of this study was to determine and characterize the highest risk period for suicide in a representative sample of first-episode psychosis (FEP) patients. Suicidal behaviour prior to first presentation of psychosis and during a 3-year follow-up was examined in a sample of 397 individuals. Risk factors for suicidal behaviour during specific time periods were investigated and compare…

Are there specific neuropsychological deficits underlying poor insight in first episode psychosis?

2011

Insight in psychosis is a multi-dimensional phenomenon, and has been hypothesised to have some sort of neuropsychological basis. It is unclear to what extent specific neuropsychological abilities are able to predict insight beyond the effect of generalised cognitive ability. We aimed to test this, alongside the relationship of insight with illness duration and diagnosis, in a sample of first episode psychosis patients. We recruited 102 patients experiencing their first episode of psychosis and assessed their insight, symptoms, diagnosis as well as administering a full neuropsychological battery. Low insight was related to worse performance in a variety of neuropsychological tasks. Regressio…

Duration of active psychosis and functional outcomes in first-episode non-affective psychosis.

2018

AbstractBackground:The duration of untreated psychosis (DUP) has been associated with negative outcomes in psychosis; however, few studies have focused on the duration of active psychotic symptoms after commencing treatment (DAT). In this study, we aimed to evaluate the effect of DUP and DAT on functional long-term outcomes (3 years) in patients with early psychosis.Methods:We evaluated the Scale for the Assessment of Positive Symptoms (SAPS) at frequent intervals for 3 years after presentation to determine the DAT for 307 individuals with first-episode psychosis together with DUP and clinical variables. The functional outcomes were assessed using the Disability Assessment Scale (DAS) at th…

Diabetes mellitus prevalence and control in sleep-disordered breathing: The European Sleep Apnea Cohort (ESADA) study

2014

BACKGROUND: OSA is associated with an increased risk of cardiovascular morbidity. A driver of this is metabolic dysfunction and in particular type 2 diabetes mellitus (T2DM). Prior studies identifying a link between OSA and T2DM have excluded subjects with undiagnosed T2DM, and there is a lack of population-level data on the interaction between OSA and glycemic control among patients with diabetes. We assessed the relationship between OSA severity and T2DM prevalence and control in a large multinational population.METHODS: We performed a cross-sectional analysis of 6,616 participants in the European Sleep Apnea Cohort (ESADA) study, using multivariate regression analysis to assess T2DM prev…

Different prognosis in hospitalized patients with influenza one season after the pandemic H1N1 influenza of 2009-2010 in Spain

2013

Background The present report compares prognosis in hospitalized cases with the H1N1 pandemic virus in two seasons. Methods Two series of hospitalized patients with laboratory-confirmed H1N1 pandemic influenza have been compared: 813 in the season 2009–2010 and 707 in the season 2010–2011. A detailed history of variables preceding hospital admission and during hospitalization was obtained by interview and clinical charts. A combined endpoint of death admission to intensive care was used as outcome due to the low number of deaths. Logistic regression was applied in the analysis for adverse outcome. Results Patients of the second season had different characteristics than in the first one (old…
