No evidence for attenuated stress-induced extrastriatal dopamine signaling in psychotic disorder
2015
AbstractStress is an important risk factor in the etiology of psychotic disorder. Preclinical work has shown that stress primarily increases dopamine (DA) transmission in the frontal cortex. Given that DA-mediated hypofrontality is hypothesized to be a cardinal feature of psychotic disorder, stress-related extrastriatal DA release may be altered in psychotic disorder. Here we quantified for the first time stress-induced extrastriatal DA release and the spatial extent of extrastriatal DA release in individuals with non-affective psychotic disorder (NAPD). Twelve healthy volunteers (HV) and 12 matched drug-free NAPD patients underwent a single infusion [18F]fallypride positron emission tomogr…
Association of Low Striatal Dopamine D2Receptor Availability With Nicotine Dependence Similar to That Seen With Other Drugs of Abuse
2008
All drugs of abuse induce a phasic dopamine release within the striatum that does not undergo habituation. Prolonged substance consumption impairs the natural function of the mesolimbic dopamine system, as shown by a decrease in the availability of striatal dopamine 2 (D(2)) receptors in patients suffering from cocaine, heroin, amphetamine, and alcohol dependence. However, it is unclear whether similar changes can also be observed in heavy-smoking nicotine-dependent smokers.In vivo D(2)/D(3) receptor availability was determined with [ (18)F]fallypride positron emission tomography in 17 heavy-smoking nicotine-dependent subjects and in 21 age-matched never-smoking comparison subjects. The smo…
Job satisfaction and quality of life among home care workers: a comparison of home care workers who are and who are not informal carers
2010
ABSTRACTBackground: Job satisfaction and quality of life among home care workers who serve simultaneously as informal carers for their own family members have seldom been explored. This study examined how this dual role influences job satisfaction and quality of life by comparing these dual carers with home care workers who do not provide informal care. The study also explored whether the factors related to job satisfaction and quality of life between these two groups were different.Method: Standardized self-administered questionnaires (Job Satisfaction Survey, the World Health Organization Quality of Life (WHOQOL) scales and various social demographic questions) were administered to the tw…
Domain-specific associations between disability and depression, anxiety, and somatization in primary care patients
2018
Abstract This study explores the associations between different disability domains and the most prevalent symptoms of mental disorders in primary care patients (i.e. depression, anxiety, and somatization). A total of 1241 participants from 28 primary care centres completed self-report measures of depression, anxiety, and somatization. This same sample also completed the Sheehan Disability Scale (SDS) to assess functional impairment in work, social life, and family life domains. Associations between the symptoms and each disability domain were examined using hierarchical regression analyses. Depression emerged as the strongest predictor of all three disability domains. Somatization was assoc…
Subjective neurocognition and quality of life in patients with bipolar disorder and siblings.
2018
Abstract Background Bipolar disorder (BD) is associated with significant neurocognitive and functional impairment, which may progress across stages. However, the potential progression of subjective cognitive complaints and quality of life (QoL) has not been addressed. Our main objective was to assess subjective cognitive complaints and QoL on euthymic patients with BD and their healthy siblings. Methods Four groups were compared: euthymic patients with type I BD in the early (n = 25) and late (n = 23) stages, their healthy siblings (latent stage; n = 23) and healthy controls (n = 21). Cognitive complaints and QoL were assessed using the COBRA and WHO-QoLBREF questionnaires, respectively. Re…
Reduced oxytocin receptor gene expression and binding sites in different brain regions in schizophrenia: A post-mortem study
2016
Schizophrenia is a severe neuropsychiatric disorder with impairments in social cognition. Several brain regions have been implicated in social cognition, including the nucleus caudatus, prefrontal and temporal cortex, and cerebellum. Oxytocin is a critical modulator of social cognition and the formation and maintenance of social relationships and was shown to improve symptoms and social cognition in schizophrenia patients. However, it is unknown whether the oxytocin receptor is altered in the brain. Therefore, we used qRT-PCR and Ornithine Vasotocin Analog ([125I]OVTA)-based receptor autoradiography to investigate oxytocin receptor expression at both the mRNA and protein level in the left p…
Factorial invariance of a computerized version of the GAD-7 across various demographic groups and over time in primary care patients.
2019
Abstract Background The Generalized Anxiety Disorder 7-item scale (GAD-7) is commonly used by clinicians and researchers to screen for anxiety disorders and to monitor anxiety symptoms in primary care. However, findings regarding its factor structure are mixed, with most studies reporting a best-fitting for a one-factor structure, whereas others indicate a two-factor model. To be valid for comparisons, the GAD-7 should measure the same latent construct with the same structure across groups and over time. We aimed to examine the best-fit factor structure model of the GAD-7 among primary care patients and to evaluate its measurement invariance. Methods A total of 1255 patients completed the c…
A computerized version of the Patient Health Questionnaire-4 as an ultra-brief screening tool to detect emotional disorders in primary care
2018
Abstract Background The Patient Health Questionnaire-4 (PHQ-4) is an ultra-brief self-report consisting of a 2-item depression scale (PHQ-2) and a 2-item anxiety scale (GAD-2). The aim of the present study is to determine the psychometric properties of a computerized version of the PHQ-4 used to detect emotional disorders (anxiety and depression) in the primary care setting. Method A total of 1052 patients with suspected anxiety, depression, or somatic symptoms were recruited from 28 primary care centres participating in the PsicAP trial and completed the full version of the computerized PHQ. In addition, 178 of these patients also underwent in clinical interviews as a gold standard. Result…
The point prevalence of depression and associated sociodemographic correlates in the general population of Latvia
2013
Abstract Aim To determine the point prevalence of depression in the general Latvian population and to explore the associated sociodemographic characteristics. Methods The study was part of the cross-sectional survey on the general population on substance use in Latvia in 2011. It consisted of face-to-face interviews of a randomised stratified multi-stage probability sample. In total, 4493 persons were included, aged between 15 and 64. To assess depression, the participants were interviewed using the Patient Health Questionnaire-9; a score of ≥10 was defined as indicating the presence of a depressive episode. Socio-demographic, subjective health status and alcohol use were assessed using the…
Psychometric properties of the Haitian Creole version of the Resilience Scale with a sample of adult survivors of the 2010 earthquake
2015
Abstract Background Resilience is defined as the ability of people to cope with disasters and significant life adversities. The present paper aims to investigate the underlying structure of the Creole version of the Resilience Scale and its psychometric properties using a sample of adult survivors of the 2010 earthquake. Methods A parallel analysis was conducted to determine the number of factors to extract and confirmatory factor analysis was performed using a sample of 1355 adult survivors of the 2010 earthquake from people of specific places where earthquake occurred with an average age of 31.57 (SD = 14.42). All participants completed the Creole version of Resilience Scale (RS), the Imp…
