Nonlinear analysis of sleep EEG data in schizophrenia: calculation of the principal Lyapunov exponent
1995
The generating mechanism of the electroencephalogram (EEG) points to the hypothesis that EEG signals derive from a nonlinear dynamic system. Hence, the unpredictability of the EEG might be considered as a phenomenon exhibiting its chaotic character. The essential property of chaotic dynamics is the so-called sensitive dependence on initial conditions. This property can be quantified by calculating the system's first positive Lyapunov exponent, L1. We calculated L1 for sleep EEG segments of 13 schizophrenic patients and 13 control subjects that corresponded to sleep stages I, II, III, IV and REM (rapid eye movement), as defined by Rechtschaffen and Kales, for the lead positions Cz and Pz.

Emotion recognition from facial expressions: a normative study of the Ekman 60-Faces Test in the Italian population.
2013
The Ekman 60-Faces (EK-60F) Test is a well-known neuropsychological tool assessing emotion recognition from facial expressions. It is the most employed task for research purposes in psychiatric and neurological disorders, including neurodegenerative diseases, such as the behavioral variant of Frontotemporal Dementia (bvFTD). Despite its remarkable usefulness in the social cognition research field, to date, there are still no normative data for the Italian population, thus limiting its application in a clinical context. In this study, we report procedures and normative data for the Italian version of the test. A hundred and thirty-two healthy Italian participants aged between 20 and 79 years…
A double-blind study comparing paroxetine and maprotiline in depressed outpatients.
1997
A double-blind multicenter randomized parallel group study comparing paroxetine and maprotiline was carried out in a total of 544 outpatients. Included were patients with varying degrees of severity of depressive symptoms who fulfilled modified RDC criteria for either Minor or Major Depression and showed a HAMD-17 score of > or = 13. No concomitant benzodiazepine treatment was allowed. Duration of treatment was 6 weeks, after an initial wash-out period. Doses were fixed during the first 3 weeks of treatment, patients receiving either 20 mg paroxetine or 100 mg maprotiline daily. An option for dose escalation was provided for insufficient responders after 3 weeks. The weekly assessments comp…
Online Self-Help as an Add-On to Inpatient Psychotherapy: Efficacy of a New Blended Treatment Approach.
2017
<b><i>Background:</i></b> Depression is one of the most frequent and costly mental disorders. While there is increasing evidence for the efficacy of online self-help to improve depression or prevent relapse, there is little evidence in blended care settings, especially combined with inpatient face-to-face psychotherapy. Therefore, we evaluated whether an evidence-based online self-help program improves the efficacy of inpatient psychotherapy. <b><i>Methods:</i></b> A total of 229 depressed patients were randomly allocated either to an online self-help program (intervention group [IG]; Deprexis) or an active control group (CG; weekly online inf…
Exploring the relationship between demographic and disease-related variables and perceived effect of health status on sexual activity in patients wit…
2017
To explore the relationship between demographic and disease-related variables and the perceived effect of health status on sexual activity in patients with axial spondyloarthritis (ax-SpA).The study assessed 379 ax-SpA patients consecutively recruited from two rheumatology outpatient clinics. Data collection included information on demographics, markers and measures of ax-SpA disease, treatment, comorbidity, and health-related quality of life (HRQoL) using the Short Form-36. The perceived effect of health status on sexual activity was assessed using question 15 in the HRQoL instrument 15D.The mean age of the patients was 45.6 years, 66.5% were men, 87.3% were human leucocyte antigen-B27 pos…
Adherence predictors in an Internet-based Intervention program for depression
2017
Internet-delivered psychotherapy has been demonstrated to be effective in the treatment of depression. Nevertheless, the study of the adherence in this type of the treatment reported divergent results. The main objective of this study is to analyze predictors of adherence in a primary care Internet-based intervention for depression in Spain. A multi-center, three arm, parallel, randomized controlled trial was conducted with 194 depressive patients, who were allocated in self-guided or supported-guided intervention. Sociodemographic and clinical characteristics were gathered using a case report form. The Mini international neuropsychiatric interview diagnoses major depression. Beck Depressio…
Virtual reality exposure and imaginal exposure in the treatment of fear of flying: a pilot study
2013
Fear of flying (FF) is an impairing psychological disorder that is extremely common in developed countries. The most effective treatment for this particular type of phobia is exposure therapy. However, there are few studies comparing imaginal exposure (IE) and virtual reality (VR) exposure for the treatment of FF. The present study compared the effectiveness of these two approaches using two manualized interventions based on the exposure technique. Patients with FF ( N = 15) were randomly assigned to either VR ( n = 7) or IE therapy ( n = 8), consisting of a total of eight sessions: two assessment sessions (pre-treatment and after the real flight) and six exposure therapy sessions, which w…
The impact of some behavioral aspects on periodontal disease in a group of Romanian students - an epidemiological survey.
2014
Abstract Aims To investigate the prevalence of periodontitis in a young population representative for the North-western part of Romania (Transylvania) and to identify possible risk indicators of periodontitis. Methods The study is a cross-sectional epidemiological survey. The subjects were students randomly sampled from three universities in Cluj-Napoca and high school students from the neighboring city of Bistrita. The sample size of the population was calculated. Overall, 623 subjects aged 16–35 years were evaluated, of which 488 were university students and 135 high school students. A structured questionnaire was administrated to collect information on socio-behavioral status and oral hy…
Risperidone Versus Haloperidol and Amitriptyline in the Treatment of Patients With a Combined Psychotic and Depressive Syndrome
1998
In a multicenter, double-blind, parallel group trial, the efficacy of risperidone (RIS) was compared with a combination of haloperidol and amitriptyline (HAL/AMI) over 6 weeks in patients with coexisting psychotic and depressive symptoms with either a schizoaffective disorder, depressive type, a major depression with psychotic features, or a nonresidual schizophrenia with major depressive symptoms according to DSM-III-R criteria. A total of 123 patients (62 RIS; 61 HAL/AMI) were included; the mean daily dosage at endpoint was 6.9 mg RIS versus 9 mg HAL combined with 180 mg AMI. Efficacy results for those 98 patients (47 RIS; 51 HAL/AMI) who completed at least 3 weeks of double-blind treatme…
Requestioning depression in patients with cancer: Contribution of somatic and affective symptoms to Beck's Depression Inventory
2007
Background: Depressive symptoms are a major complaint reported by cancer patients. Somatic and affective symptoms can contribute to depression. Patients and methods: We investigated the prevalence of somatic and affective depressive symptoms with the Beck Depression Inventory (BDI) in 213 hospitalized cancer patients prior to the start of chemotherapy. Results: Seventeen of 213 patients (8%) were screened positive for major depression; 40 (19%) had mild to moderate depressive symptoms. The corresponding figures for somatic and affective symptoms were 33.3% and 2.8% in the patients with major depression and 23.0% and 8.0% in those with mild to moderate depressive symptoms. Female patients, p…
