A novel multidimensional questionnaire for the assessment of emotional dysregulation in adolescents: Reactivity, Intensity, Polarity and Stability qu…
2021
Abstract Background The failure to regulate emotions, namely emotional dysregulation (ED), is a relevant construct in adolescent psychiatry, in terms of prognostic and developmental implications. We developed and validated a novel self-report questionnaire for the assessment of ED, the RIPoSt-Y, both in clinical and non-clinical samples. Methods Items selection and subscales construction were conducted on healthy controls (n=374), while test-retest reliability was evaluated in a subsample (n=72); internal consistency was examined both in the control group and in two clinical samples, respectively including patients with Bipolar Spectrum Disorders (BSD; n=44) and ADHD (n=34). Construct, conc…
Neurocognitive endophenotypes (endophenocognitypes) from studies of relatives of bipolar disorder subjects: a systematic review.
2008
Abstract Background There is growing interest to research neurocognition as a putative endophenotype for subjects with bipolar disorders (BD). The authors sought to review the available literature focused on relatives of subjects with bipolar disorder (BD-Rels) and identify suitable cognitive candidates to endophenotypes or endophenocognitypes. Method A systematic review was conducted in Medline, EMBASE and PsycINFO databases (1980–July 2007), supplemented with a manual search of reference lists. Results Twenty-three cross-sectional papers of discordant twins (4 studies), genetic high-risk subjects (7), and different BD-Rel groups (12) met the inclusion criteria and evaluated 532 BD-Rels. I…
Motor speed predicts stability of cognitive deficits in both schizophrenic and bipolar I patients at one-year follow-up
2009
Background We examined whether motor speed assessed by the finger tapping test predicts generalized and specific stable deficits because of a common patho-genic process in bipolar and schizophrenic patients. Methods: One hundred and two patients underwent a battery of neuropsychological tests. Patients with a score of less than one standard deviation from their siblings' sample in two assessments with an interval of one year were defined as suffering from stable deficits because of a common pathogenic process. In addition to univariate analyses, factor analyses, ordinal logistic regression, and multiple linear regressions were used. A general score was also calculated. Results: No differenc…
The relationship of symptom dimensions with premorbid adjustment and cognitive characteristics at first episode psychosis: Findings from the EU-GEI s…
2021
Premorbid functioning and cognitive measures may reflect gradients of developmental impairment across diagnostic categories in psychosis. In this study, we sought to examine the associations of current cognition and premorbid adjustment with symptom dimensions in a large first episode psychosis (FEP) sample. We used data from the international EU-GEI study. Bifactor modelling of the Operational Criteria in Studies of Psychotic Illness (OPCRIT) ratings provided general and specific symptom dimension scores. Premorbid Adjustment Scale estimated premorbid social (PSF) and academic adjustment (PAF), and WAIS-brief version measured IQ. A MANCOVA model examined the relationship between symptom di…
O impacto da história de sintomas psicóticos na função cognitiva de doentes bipolares eutímicos: comparação com doentes esquizofrênicos e controles s…
2011
BACKGROUND: About two-thirds of patients with bipolar disorder (BD) have a lifetime history of at least one psychotic symptom. Objective: To compare the neurocognitive performance of four groups: BD patients with and without a history of psychotic symptoms (BD HPS+ and BD HPS-, respectively); patients with schizophrenia (SZ); and healthy control (HC) subjects. METHOD: In this cross-sectional study, 35 stabilized patients with SZ, 79 euthymic (44 HPS+ and 35 HPS-) patients with BD, and 50 HC were administered a comprehensive battery of neuropsychological tests. RESULTS: There was worse neurocognitive functioning in both BD and SZ patients compared to HC. Overall, data from both groups of BD …
Coordinates for quasi-Fuchsian punctured torus space
1998
We consider complex Fenchel-Nielsen coordinates on the quasi-Fuchsian space of punctured tori. These coordinates arise from a generalisation of Kra's plumbing construction and are related to earthquakes on Teichmueller space. They also allow us to interpolate between two coordinate systems on Teichmueller space, namely the classical Fuchsian space with Fenchel-Nielsen coordinates and the Maskit embedding. We also show how they relate to the pleating coordinates of Keen and Series.
Are affective temperaments determinants of quality of life in euthymic patients with bipolar disorder?
2018
Background: Bipolar disorder (BD) is a disabling illness that is associated with low quality of life (QoL). This low QoL goes further than mood episodes, which suggests that stable traits, such as affective temperaments, can cause functional impairment. Objective: Our study analyses the impact of affective temperaments on the Physical Component Summary (PCS) and Mental Component Summary (MCS) of QoL in euthymic BD patients. Methods: A multicentre study was conducted in 180 euthymic BD patients and 95 healthy controls. Firstly, statistical analyses were performed to compare QoL and affective temperaments between the two groups. Secondly, Adaptive Lasso Analysis was carried out to identify th…
Computer Modeling of Luminescence in ABO3 Perovskites
2001
ABSTRACTWe suggest theoretical interpretation to a long-debated discussion on a nature of the intrinsic “green” luminescence observed in many ABO3 perovskites. For this purpose we performed quantum chemical calculations using the Intermediate Neglect of the Differential Overlap combined with the Large Unit Cell periodic model. Triplet exciton which is very likely responsible for the “green” luminescence is shown to be in a good approximation a pair of nearest Jahn-Teller electron and hole polarons (a bipolaron).
Cancer and central nervous system disorders: protocol for an umbrella review of systematic reviews and updated meta-analyses of observational studies
2017
[Background] The objective of this study will be to synthesize the epidemiological evidence and evaluate the validity of the associations between central nervous system disorders and the risk of developing or dying from cancer.
