Positive symptoms in first-episode psychosis patients experiencing low maternal care and stressful life events: a pilot study to explore the role of the COMT gene.

COMT Val(158)Met moderates the effect of stress on psychotic symptoms. Exposure to stress is also associated with mesolimbic dopamine release in individuals experiencing low maternal care. We therefore test the hypothesis that recent stressful life events are associated with more severe positive symptoms (associated with mesolimbic dopamine release) in first-episode psychosis (FEP) patients who experienced low maternal care during childhood. We hypothesized that COMT Val(158)Met moderates this association. A total of 149 FEP patients recruited within the Psychosis Incident Cohort Outcome Study (PICOS) participated in the present study. Maternal care was assessed by the Parental Bonding Instrument (PBI), stressful life events were collected by the List of Events Scale and positive symptoms were assessed by the Positive and Negative Syndrome Scale (PANSS). We found that low maternal care and recent stressful life events were associated with higher level of positive symptoms at the onset (analysis of variance [ANOVA], p = 0.012), and that patients who were also homozygotes for the COMT Val(158) allele had the highest level of positive symptoms (ANOVA, p = 0.024). Low maternal care and severe stressful life events may contribute to a symptomatology characterized by more severe positive symptoms at the onset, possibly due to an increased mesolimbic dopamine release. Homozygosity for the COMT Val(158) allele seems to confer a biological predisposition to the stress-related hyperactivity of the mesolimbic dopaminergic system. The data imply that the mesolimbic dopaminergic system is involved in the mediation/modulation of the effect of stressful events on the vulnerability for psychosis.

Influence of perceived organisational factors on job burnout: survey of community mental health staff.

BACKGROUND: Staff burnout is a critical issue for mental healthcare delivery, as it can lead to decreased work performance and, ultimately, to poorer treatment outcomes. AIMS: To explore the relative weight of job-related characteristics and perceived organisational factors in predicting burnout in staff working in community-based psychiatric services. METHOD: A representative sample of 2000 mental health staff working in the Veneto region, Italy, participated. Burnout and perceived organisational factors were assessed by using the Organizational Checkup Survey. RESULTS: Overall, high levels of job distress affected nearly two-thirds of the psychiatric staff and one in five staff members suffered from burnout. Psychiatrists and social workers reported the highest levels of burnout, and support workers and psychologists, the lowest. Burnout was mostly predicted by a higher frequency of face-to-face interaction with users, longer tenure in mental healthcare, weak work group cohesion and perceived unfairness. CONCLUSIONS: Improving the workplace atmosphere within psychiatric services should be one of the most important targets in staff burnout prevention strategies. The potential benefits of such programmes may, in turn, have a favourable impact on patient outcomes.

[Internet and psychopathology: an analysis of the use of the Web by 1075 students at secondary school]. / Internet e psicopatologia: un contributo dall'analisi dell'uso della rete da parte di 1075 studenti delle scuole superiori.

AIMS: The purpose of this research is to make a contribution to analysing the complex issue of the relationship between Internet use and psychological disorders, and proposes a survey of the typical features and effects of such use among a sample of secondary school students. PATTERN: The research was carried out on a sample of 1075 students aged 14-21 from two secondary schools, where students are prevalently male in one and female in the other; computer science is part of the teaching programme in both institutes. INSTRUMENTS USED: General Health Questionnaire (GHQ), Goldberg's 28-item version, together with a form to collect individual and social data and information about the actual use of Internet, such as number of years, number of hours a day/a week, subjective experience, quantitative-qualitative perception of the connection. RESULTS: There is a clear and significant correlation between weekly hours of use and GHQ scores. CONCLUSIONS: Analysis of our sample confirms certain statements found in the relevant literature concerning a possible relationship between the use of Internet and psychological disorders. DECLARATION OF INTEREST: none.
