Cognitive impairment is related to oxidative stress and chemokine levels in first psychotic episodes.

2011

Abstract Introduction This study measures the levels of various markers of oxidative stress and inflammation in blood samples from first-episode psychosis (FEP) patients, and examines the association between these peripheral biomarkers and cognitive performance at 6 months after treatment. Methods Twenty-eight FEP patients and 28 healthy controls (matched by age, sex and educational level) had blood samples taken at admission for assessment of total antioxidant status, superoxide dismutase (SOD), total glutathione (GSH), catalase (CAT), glutathione peroxidase, lipid peroxidation, nitrites and the chemokine monocyte chemoattractant protein-1 (MCP-1). A battery of cognitive tests was also app…

Left orbitofrontal and superior temporal gyrus structural changes associated to suicidal behavior in patients with schizophrenia.

2008

Suicidal attempts are relatively frequent and clinically relevant in patients with schizophrenia. Recent studies have found gray matter differences in suicidal and non-suicidal depressive patients. However, no previous neuroimaging study has investigated possible structural abnormalities associated to suicidal behaviors in patients with schizophrenia. A whole-brain magnetic resonance voxel-based morphometric examination was performed on 37 male patients meeting the DSM-IV criteria for schizophrenia. Thirteen (35.14%) patients had attempted suicide. A non-parametric permutation test was computed to perform the comparability between groups. An analysis of covariance (AnCova) model was constru…

Detection of Depression in Acute Schizophrenia: Sensitivity and Specificity of 2 Standard Observer Rating Scales

2006

Objective: To compare the psychometric properties of the Calgary Depression Rating Scale (CDRS) and the Hamilton Depression Rating Scale (HDRS) for severity assessment of depression in acute schizophrenia. Method: During clinical routine treatment, we investigated 119 inpatients with acute schizophrenia, using the CDRS, the HDRS, and a global 4-point Depression Severity Scale (DEP-SEV). We compared CDRS and HDRS sum scores regarding their diagnostic accuracy, with global severity of depression as the criterion. We estimated sensitivity and specificity on the basis of receiver operating characteristic curves. Results: According to global clinical ratings (DEP-SEV), 31% of patients had no dep…

Subclinical thought disorder in first-degree relatives of schizophrenic patients. Results from a matched-pairs study with the Thought Disorder Index

1995

To assess the frequency and quality of formal thought disorder in schizophrenic patients and their first-degree relatives, a consecutive series of 36 unmedicated patients, 20 siblings of these patients and 37 normal control subjects were examined with Holzman's Thought Disorder Index (TDI). As a proof of the internal validity of this tool, the patients demonstrated significantly more thought disorder than the controls as measured by the TDI total score and various subscores, which proved the internal validity of this tool in a German-speaking sample. In addition, in a pairwise comparison with controls who were individually matched by age and sex the patients' siblings had a significantly hi…

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…

Population-based validation of a German version of the Brief Resilience Scale.

2017

Smith and colleagues developed the Brief Resilience Scale (BRS) to assess the individual ability to recover from stress despite significant adversity. This study aimed to validate the German version of the BRS. We used data from a population-based (sample 1: n = 1.481) and a representative (sample 2: n = 1.128) sample of participants from the German general population (age ≥ 18) to assess reliability and validity. Confirmatory factor analyses (CFA) were conducted to compare one- and two-factorial models from previous studies with a method-factor model which especially accounts for the wording of the items. Reliability was analyzed. Convergent validity was measured by correlating BRS scores …

A psychopathological study of a group of schizophrenic patients after attempting suicide. Are there two different clinical subtypes?

2003

AbstractFifty-six schizophrenic patients at the moment of their suicidal attempt were compared to a control group of 60 patients. Schizophrenic suicidal attempters showed an identifiable clinical profile at the acute phase. Two main groups could be differentiated in regard to their reasons (depressive or psychotic) for attempting suicide.

Depression in the community: a comparison of treated and non-treated cases in two non-referred samples.

1992

Family studies in non-patient samples may help to clarify whether or not treatment-seeking behaviour is substantially determined by clinical features of depression. Life-time risks of depression were investigated by structured clinical interviews (SADS-LA) in both a high-risk sample of depressed patients' first-degree relatives and an unscreened control sample of the general population: 34.6% of the high-risk sample versus 23.1% of controls were cases of depression, with a female preponderance in both groups. The rates of treated depression were 17.0% versus 8.5%. Female sex, greater age, higher severity of episodes, manic or hypomanic episodes recurrent course, and introverted and anancast…

[Anxiety, depression and risk consumption of alcohol in a sample of university students].

2018

The university student is vulnerable to the adverse effects of many stress factors that can lead to depressive symptoms, anxiety and alcohol abuse, causing an increase in the burden of illness in young people. The aim of the study was to measure depressive symptoms, anxiety levels, and harmful alcohol consumption within the student population of the University of Palermo.An online questionnaire was sent by e-mail to the 8500 students enrolled in the (ERSU) Regional Office for the Right to University Study's mailing list in Palermo. It was evaluated the severity of depressive symptoms through the Quick Inventory of Depressive Symptomatology-Self Report, anxiety symptoms using the Beck Anxiet…
