Homeless men with psychosis are spending more time shelterless.

OBJECTIVE: The objective of this study was to determine if homeless men with psychosis in central Melbourne have spent a greater proportion of the past 12 months in homeless settings as compared with the same group 15 years previously. METHOD: A 12-month accommodation history was collected from all men with psychosis assessed by a homeless outreach mental health team over a 12-month period commencing 2018 and compared with data from 2006. RESULTS: Between 2006 and 2018, the percentage of time spent homeless in the previous 12 months rose from 50% to 80% (p = 0.0001). The mean time spent shelterless increased from 72 days to 149 days (p = 0.0001). CONCLUSIONS: The amount of time spent homeless has increased in men with psychosis assessed in central Melbourne. This finding suggests that men with psychosis are becoming increasingly entrenched in homeless settings. Addressing this trend requires an increased emphasis on assertive outreach, greater access to acute inpatient and long-term rehabilitation units, and more low cost affordable housing, including housing first facilities.

Housing First: permanent supported accommodation for people with psychosis who have experienced chronic homelessness.

OBJECTIVES: The objective of this study was to determine whether a 'housing first' permanent supported accommodation was effective in improving housing stability, continuity of care and reducing mental health admissions for persons experiencing chronic homelessness with psychosis. METHODS: A quasi prospective cohort study of 42 chronic homeless persons with psychosis accommodated in a new purpose built facility in central Melbourne. Accommodation stability, mental health service contacts and psychiatric admissions were compared across the 2 years prior, the first 2 years of placement and the 2 years after leaving. RESULTS: The mean number of mental health admissions in the first 2 years of accommodation was less (0.56, SD = 1.0) when compared with in the 2 years prior to accommodation (1.0, SD = 1.4, p = 0.05). There was an increase in the mean total number of days admitted in the 2 years after having left the supported accommodation, (33.3 days, SD = 86.7, p = 0.043) Conclusions: The accommodation of chronic homeless persons with psychosis in a 'housing first' permanent supported accommodation lead to increased housing stability and optimism, improved continuity of care and reduced psychiatric admissions.

Ionic liquid crosslinkers for chiral imprinted nanoGUMBOS.

Molecularly imprinted polymers (MIPs) are an important class of selective materials for molecular specific sensors and separations. Molecular imprinting using non-covalent interactions in aqueous conditions still remains a difficult challenge due to interruption of hydrogen-bonding or electrostatic interactions water. Newly developed crosslinking ionic liquids are demonstrated herein to overcome problems of synthesizing aqueous MIPs, adding to previous examples of ionic liquids used as monomers in non-aqueous conditions or used as MIP solvents. Vinylimidazole ionic liquid crosslinkers were synthesized and subsequently explored as matrix supports for fabrication of molecularly imprinted polymeric nanoGUMBOS (nanoparticles derived from a group of uniform materials based on organic salts). Each of the four crosslinkers incorporated a unique functional spacer between the vinylimidazole groups, and the performance of the corresponding molecularly imprinted polymers was evaluated using chiral recognition as the diagnostic. High uptake values for l-tryptophan were found in the 13-87µmol/g range; and chiral recognition was determined via binding ratios of l-tryptophan over d-tryptophan that ranged from 5:1 to 13:1 for polymers made using different crosslinkers. Not only are these materials good for chiral recognition, but the results highlight the utility of these materials for imprinting aqueous templates such as biological targets for theranostic agents.
