Previous research has explained the production and perception of speech and anomalies found in the brains and cognitive abilities of people with schizophrenia when compared with mentally healthy controls. One aspect of research that has been lacking is an explanation of auditory verbal hallucinations and referential delusions of communication that combines social cognition theory with neuroimaging evidence, with particular emphasis on detecting an intention to communicate. Developing this knowledge could reduce the difficulties faced in early detection of schizophrenia. This study aimed to find clear evidence that mentally healthy people describe sounds in certain qualitative ways and whether a diagnosis of schizophrenia influences this. Second, it aimed to identify brain regions in mentally healthy adults that are involved in the detection of auditory intention to communicate and to hypothesize regarding what could differ in schizophrenia. We conducted a selective review of literature pertaining to the development of theory of mind and its relationship to schizophrenia, with a focus on the "intention to communicate." We found that mentally healthy people should use certain brain regions, especially the superior and medial temporal gyri, and the way people with schizophrenia use their brains should differ from mentally healthy brain activation patterns shown in functional neuroimaging. Now these links and differences can be examined in more detail, using novel, schizophrenia-relevant tests.

This analysis aimed to examine the association of social dysfunction with food security status, fruit intake, vegetable intake, meal frequency and breakfast consumption in people with psychosis from the Hunter New England (HNE) catchment site of the Survey of High Impact Psychosis (SHIP). Social dysfunction and dietary information were collected using standardised tools. Independent binary logistic regressions were used to examine the association between social dysfunction and food security status, fruit intake, vegetable intake, meal frequency and breakfast consumption. Although social dysfunction did not have a statistically significant association with most diet variables, participants with obvious to severe social dysfunction were 0.872 (95% CI (0.778, 0.976)) less likely to eat breakfast than those with no social dysfunction p < 0.05. Participants with social dysfunction were therefore, 13% less likely to have breakfast. This paper highlights high rates of social dysfunction, significant food insecurity, and intakes of fruits and vegetables below recommendations in people with psychosis. In light of this, a greater focus needs to be given to dietary behaviours and social dysfunction in lifestyle interventions delivered to people with psychosis. Well-designed observational research is also needed to further examine the relationship between social dysfunction and dietary behaviour in people with psychosis.

Journal of Medical Radiation Sciences published by John Wiley & Sons Australia, Ltd on behalf of Australian Society of Medical Imaging and Radiation Therapy and New Zealand Institute of Medical Radiation Technology Introduction: High rectal doses are associated with increased toxicity. A rectal displacement device (RDD) reduces rectal dose in prostate stereotactic body radiation therapy (SBRT). This study investigates any dosimetric difference between two methods of rectal displacement (Rectafix and SpaceOAR) for prostate SBRT. Methods: Rectal dosimetry of 45 men who received SBRT within the PROMETHEUS trial was retrospectively examined, across two radiation therapy centres using the two RDD's. Men received a total dose (TD) of 19 or 20 Gy in two fractions followed by 46 Gy in 23 fractions. Centre 1 contributed 16 Rectafix and 10 SpaceOAR patients. Centre 2 contributed 19 Rectafix patients. Rectal dose volume histogram (DVH) data were recorded as a TD percentage at the following volume intervals; V1%, V2%, V5%, V10% and then 10% increments to V80%. As only one centre employed both RDD's, three sequential rectal dosimetry comparisons were performed; (1) centre 1 Rectafix versus centre 1 SpaceOAR; (2) centre 1 Rectafix versus centre 2 Rectafix and (3) centre 1+ centre 2 Rectafix versus centre 1 SpaceOAR. Results: In comparison (1) Rectafix demonstrated lower mean doses at 9 out of 11 measured intervals (P = 0.0012). Comparison (2) demonstrated a moderate difference with centre 2 plans producing slightly lower rectal doses (P = 0.013). Comparison (3) further demonstrated that Rectafix returned lower mean doses than SpaceOAR (P < 0.001). Although all dose levels were in favour of Rectafix, in absolute terms differences were small (2.6¿9.0%). Conclusions: In well-selected prostate SBRT patients, Rectafix and SpaceOAR RDD's provide approximately equivalent rectal sparing.

© 2017 Elsevier Ireland Ltd We aimed to examine and compare sex-differences in people receiving treatment for psychotic illnesses in community settings, based on long or short duration of illness; expecting association between longer illness-duration and worse outcomes in women and men. Clinical, demographic and service-use data from the Survey of High Impact Psychosis were analysed by sex and duration of illness (=5 years; =6 years), using independent t-tests, chi-square tests, one-way ANOVA, and Cramer's V. Of the 1825 participants, 47% had schizophrenia, 17.5% bipolar and 16.1% schizo-affective disorders. More women than men had undertaken post-school education, maintained relationships, and been living in their own homes. Women with a shorter-illness-duration showed social functioning equivalent to non-ill women in the general population. Men tended to have an early illness onset, show premorbid dysfunction, be single, show severe disability, and to use illicit substances. Men with a longer-illness-duration were very socially disadvantaged and isolated, often experiencing homelessness and substance use. Men with a short-illness-duration were most likely to be in paid employment, but two-thirds earned less than $AUD500 per fortnight. Men with longer-illness-duration showed most disability, socially and globally. Interventions should be guided by diagnosis, but also by a person's sex and duration of illness.

Research demonstrates that people living with serious mental illness (SMI) contend with widespread public stigma; however, little is known about the specific experiences of stigma that mothers, and in particular fathers, with SMI encounter as parents. This study aimed to explore and compare the experiences of stigma for mothers and fathers with SMI inferred not only by living with a mental illness but also potential compounding gender effects, and the associated impact of stigma on parenting. Telephone surveys were conducted with 93 participants with SMI who previously identified as parents in the Second Australian National Survey of Psychosis. Results indicated that mothers were more likely than fathers to perceive and internalise stigma associated with their mental illness. Conversely, fathers were more inclined to perceive stigma relating to their gender and to hold stigmatising attitudes towards others. Mental illness and gender stigma predicted poorer self-reported parenting experiences for both mothers and fathers. These findings may assist in tailoring interventions for mothers and fathers with SMI.
