Questionnaire on Attitude towards Research and Care (QuARC): a survey of patients with psychosis.

Background: The patients' appraisal, satisfaction and attitude toward research is crucial to obtain reliable information, in psychiatry frequently not objective.Aim: We operationalised the information derived from studies on satisfaction and attitude towards research and developed a standardized measure, whose internal consistency and factor structure was investigated.Method: The Questionnaire on Attitude towards Research and health Care (QuARC) is a 10-item self-report scale, administered to 116 patients with psychotic disorders participating in research protocols. Exploratory factor analysis was conducted and internal consistency evaluated.Results: Two factors have been identified: one labelled External Factor, including items related to information on the received treatment, relationship with third parties, and one labelled Internal Factor with items related to the disorder, perceived well-being and contribution to scientific knowledge. Cronbach's alpha internal consistencies were good.Conclusions: The QuARC is easy to use, well accepted, with good psychometric properties. The constructs identified are different from the original issues addressed (i.e. attitude and satisfaction), prevailing different constructs closer to the patient opinion on the research and personal condition. These constructs identify dimensions useful to delineate and understand the patients' experience of participating in a scientific project as well as their satisfaction.

Source monitoring task in a sample of in-patients with verbal auditory hallucinations compared to control sample.

Patients with psychosis, especially those with specific positive symptoms such as auditory verbal hallucinations, show a source monitoring deficit, the cognitive process involved in the recognition of the information source. This defect can lead to the erroneous conclusion that self-generated thoughts are not "proper" but derive from an external source. We evaluated 37 patients diagnosed with psychotic disorder and 40 healthy controls using a modified version of the Reality Monitoring Task developed by Larøi et al. in 2004. The patients were also evaluated with PANSS, VGF, PSP. We have found that the performance of the Source Monitoring Task differs between patients with hallucinations and controls. According to the literature we can therefore state that patients with hallucinations are characterized by a difficulty in identifying the source of the information they perceive. Our study also adds a new finding to the literature: the source monitoring dysfunction is not due to the presence of current hallucinatory symptomatology but could be considered a stable trait in psychotic patients.

Paranoia, depression and lack of insight in schizophrenia: a suggestion for a mediation effect.

INTRODUCTION: Delusional symptoms are heterogeneous and differentially related to insight, depression and another psychological construct, such as deservedness. In this study we explore models of relationships among these constructs, by hypothesizing that lack of insight could predict depression or paranoia, representing these variables outcome or mediator variables alternatively. MATERIALS: We evaluated positive psychotic symptoms, depression, persecution, deservedness and insight in a clinical sample of 81 people with schizophrenia or other psychotic spectrum disorders. Using multiple regression analyses we found 2 significant models. In the first one the lack of insight is negatively associated with depression and negatively related to persecution that, as mediator, is positively associated with depression. In the second model, lack of insight is negatively associated with persecution and negatively related to depression that, as mediator, is positively associated with persecution. CONCLUSIONS: Persecution and depression could be not only predicted by insight but this prediction could also be mediated by the same variables. In both clinical models found in this study, insight does have a relevant role because the awareness about symptom/illness is crucial to the symptoms change. However, having good insight into schizophrenia can also be paradoxically associated with negative subjective states related to depression (the so-called "insight paradox").

Medium- and long-term health effects of earthquakes in high-income countries: a systematic review and meta-analysis.

Background: Accurate monitoring of population health is essential to ensure proper recovery after earthquakes. We aimed to summarize the findings and features of post-earthquake epidemiological studies conducted in high-income countries and to prompt the development of future surveillance plans. Methods: Medline, Scopus and six sources of grey literature were systematically searched. Inclusion criteria were: observational study conducted in high-income countries with at least one comparison group of unexposed participants, and measurement of health outcomes at least 1 month after the earthquake. Results: A total of 52 articles were included, assessing the effects of 13 earthquakes that occurred in eight countries. Most studies: had a time-series (33%) or cross-sectional (29%) design; included temporal comparison groups (63%); used routine data (58%); and focused on patient subgroups rather than the whole population (65%). Individuals exposed to earthquakes had: 2% higher all-cause mortality rates [95% confidence interval (CI), 1% to 3%]; 36% (95% CI, 19% to 57%) and 37% (95% CI, 29% to 46%) greater mortality rates from myocardial infarction and stroke, respectively; and 0.16 higher mean percent points of glycated haemoglobin (95% CI, 0.07% to 0.25% points). There was no evidence of earthquake effects for blood pressure, body mass index or lipid biomarkers. Conclusions: A more regular and coordinated use of large and routinely collected datasets would benefit post-earthquake epidemiological surveillance. Whenever possible, a cohort design with geographical and temporal comparison groups should be used, and both communicable and non-communicable diseases should be assessed. Post-earthquake epidemiological surveillance should also capture the impact of seismic events on the access to and use of health care services.

Alterations of cerebral white matter structure in psychosis and their clinical correlations: a systematic review of Diffusion Tensor Imaging studies.

Schizophrenia is a common, severe and chronically disabling mental illness. Most of MRI studies in schizophrenia suggest the involvement of white matter (WM) pathology in multiple cerebral regions in the neurobiology of this condition. White matter fiber tracts connecting numerous cortical regions have been the focus of a number of studies using a magnetic resonance technique called "Diffusion Tensor Imaging" (DTI). A literature search of published DTI studies was conducted using the major database National Centre for Biotechnology information (NCBI) PubMed (MEDLINE). Our review covers 95 published papers. We summarise the main DTI findings involving the different brain regions in patients affected by or at high-risk for psychosis; we discuss clinical implications of these white matter disruptions and the limitations of current studies, listing the potential confounds and suggesting potential future research directions.

[Medium- and long-term health effects of the L'Aquila earthquake (Central Italy, 2009) and of other earthquakes in high-income Countries: a systematic review]. / Effetti sulla salute a medio e lungo termine del terremoto dell'Aquila del 2009 e di altri terremoti avvenuti in Paesi ad alto reddito: una revisione sistematica della letteratura.

OBJECTIVES: to compare the methodological characteristics of the studies investigating the middle- and long-term health effects of the L'Aquila earthquake with the features of studies conducted after other earthquakes occurred in highincome Countries. DESIGN: a systematic comparison between the studies which evaluated the health effects of the L'Aquila earthquake (Central Italy, 6th April 2009) and those conducted after other earthquakes occurred in comparable settings. METHODS: Medline, Scopus, and 6 sources of grey literature were systematically searched. Inclusion criteria comprised measurement of health outcomes at least one month after the earthquake, investigation of earthquakes occurred in high-income Countries, and presence of at least one temporal or geographical control group. RESULTS: out of 2,976 titles, 13 studies regarding the L'Aquila earthquake and 51 studies concerning other earthquakes were included. The L'Aquila and the Kobe/Hanshin- Awaji (Japan, 17th January 1995) earthquakes were the most investigated. Studies on the L'Aquila earthquake had a median sample size of 1,240 subjects, a median duration of 24 months, and used most frequently a cross sectional design (7/13). Studies on other earthquakes had a median sample size of 320 subjects, a median duration of 15 months, and used most frequently a time series design (19/51). CONCLUSIONS: the L'Aquila studies often focussed on mental health, while the earthquake effects on mortality, cardiovascular outcomes, and health systems were less frequently evaluated. A more intensive use of routine data could benefit future epidemiological surveillance in the aftermath of earthquakes.
