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.

Cannabis use is frequent among first-episode psychosis (FEP) patients and has been associated with several clinical features. This study aimed in an FEP sample to determine whether cannabis use is associated with (1) a higher level of positive symptoms, a lower level of depression and a better premorbid adjustment, (2) an earlier age of onset, and a better premorbid IQ. The study was conducted within the framework of the Psychosis Incident Cohort Outcome Study (PICOS), a multisite collaborative research on FEP patients who attended the psychiatric services in Veneto Region, Italy. Standardized instruments were used to collect sociodemographic, clinical, and drug use data. A total of 555 FEP patients met the inclusion criteria, 517 of whom received an ICD-10 diagnosis of psychosis; 397 (55% males; mean age: 32 yrs ± 9.5) were assessed. Out of these, 311 patients agreed to be interviewed on drug and alcohol misuse; 20.3% was positive for drug misuse: cannabis (19.0%), cocaine (3.9%), and hallucinogens (3.9%). Cannabis use was not associated with a higher level of positive symptoms, but correlated with less severe depressive symptoms. No relationship was observed between premorbid adjustment or IQ and cannabis use. FEP patients who used cannabis had an earlier age of onset than abstinent patients, even after adjusting for gender and diagnosis. Our results suggest a possible causal role of cannabis in triggering psychosis in certain vulnerable subjects. Particular attention must be paid to this behaviour, because reducing cannabis use can delay or prevent some cases of psychosis.

BACKGROUND. This paper examined the hypothesis that males with first-episode psychosis (FEP) experience lower pre-morbid adjustment, greater social disability and more self-perceived needs at illness onset than females(by controlling for duration of untreated psychosis, diagnosis, age and symptoms at onset). Results disconfirming this hypothesis were thought to suggest the potentially mediating role of social context in determining the impact of symptoms and disability on the everyday lives of male patients in the early phase of psychosis. METHOD. A large epidemiologically representative cohort of FEP patients (n=517) was assessed within the Psychosis Incident Cohort Outcome Study (PICOS) framework – a multi-site research project examining incident cases of psychosis in Italys Veneto region. RESULTS. Despite poorer pre-morbid functioning and higher social disability at illness onset, males reported fewer unmet needs in the functioning domain than females did. An analysis of help provided by informal care givers showed that males received more help from their families than females did. This finding led us to disconfirm the second part of the hypothesis and suggest that the impact of poorer social performance and unmet needs on everyday life observed in male patients might be hampered by higher tolerance and more support within the family context.CONCLUSIONS. These findings shed new light on rarely investigated sociocultural and contextual factors that may account for the observed discrepancy between social disability and needs for care in FEP patients. They also point to a need for further research on gender differences, with the ultimate aim of delivering gender-sensitive effective mental health care.

BACKGROUND Considerable variations in the incidence of psychosis have been observed across countries, in terms of age, gender, immigration status, urbanicity and socioeconomic deprivation. AIMS To evaluate the incidence rate of first-episode psychosis in a large area of north-eastern Italy and the distribution of the above-mentioned risk factors in individuals with psychoses. METHOD Epidemiologically based survey. Over a 3-year period individuals with psychosis on first contact with services were identified and diagnosed according to ICD-10 criteria. RESULTS In total, 558 individuals with first-episode psychosis were identified during 3,077,555 person-years at risk. The annual incidence rate per 100,000 was 18.1 for all psychoses, 14.3 for non-affective psychoses and 3.8 for affective psychoses. The rate for all psychoses was higher in young people aged 20-29 (incidence rate ratio (IRR) = 4.18, 95% CI 2.77-6.30), immigrants (IRR = 2.26, 95% CI 1.85-2.75) and those living in the most deprived areas (IRR = 2.09, 95% CI 1.54-2.85). CONCLUSIONS The incidence rate in our study area was lower than that found in other European and North American studies and provides new insights into the factors that may increase and/or decrease risk for developing psychosis.

Although the etiology of aggression is multifactorial, many studies have associated the Val158Met polymorphism of the COMT with aggression in schizophrenia. This study tests the hypothesis that Met/Met patients display more episodes of aggression and violent behaviour than Val/Val patients in a 6 year follow-up cohort of subjects with schizophrenia in contact with the South-Verona Community-based Mental Health Service. Out of the 141 subjects with an ICD-10 SCAN-confirmed diagnosis of schizophrenia, 115 completed both baseline and follow-up assessments (81.6% of the baseline cohort). Of these, 80 subjects (70%) were genotyped and rated for aggression using the Overt Aggression Scale. Met/Met homozygous patients had higher aggressive behaviour compared to Val/Val homozygous subjects. Antipsychotic dosage, alcohol and drug abuse were taken into account as confounders. The Met/Met genotype of COMT may have an effect on aggressive behaviour in schizophrenia because norepinephrine is less effectively inactivated.

Background/Aims: Reduced left superior temporal gyrus (STG) volume is one of the most replicated imaging findings in schizophrenia. However, it remains unclear whether genes play any role in our understanding of such structural alteration. It has been proposed that Neuregulin 1 (NRG1) might be a promising gene involved in schizophrenia, because of its role in neurodevelopment and neuroplasticity. In this study, the association between NRG1 and STG anatomy in patients with schizophrenia was explored for the first time. Methods: We investigated a 1-year treated prevalence cohort of patients with schizophrenia in contact with the South Verona Community-Based Mental Health Service. A blood sample was collected for DNA extraction and brain structure was assessed with an MRI scan. A total of 27 subjects with schizophrenia underwent both assessments and were included in the study. Results: We investigated the association between the polymorphism SNP8NRG222662 (rs4623364) of NRG1 and volume of the STG. We found that patients homozygous for the C allele had reduced left STG gray and white matter volumes in comparison to those homozygous for the G allele (p < 0.01 and p < 0.001, respectively). Conclusions: This exploratory study suggests that NRG1 may be involved in determining STG size in schizophrenia, and may play a role in the neurogenetic basis of the language disturbances seen in this disorder. However, due to our small sample size, the results should be regarded as preliminary and replicated in a larger sample.
