The photosynthetic pathway of plants is a fundamental trait that influences terrestrial environments from the local to global level. The distribution of different photosynthetic pathways in Australia is expected to undergo a substantial shift due to climate change and rising atmospheric CO; however, tracking change is hindered by a lack of data on the pathways of species, as well as their distribution and relative cover within plant communities. Here we present the photosynthetic pathways for 2428 species recorded across 541 plots surveyed by Australia's Terrestrial Ecosystem Research Network (TERN) between 2011 and 2017. This dataset was created to facilitate research exploring trends in vegetation change across Australia. Species were assigned a photosynthetic pathway using published literature and stable carbon isotope analysis of bulk tissue. The photosynthetic pathway of species can be extracted from the dataset individually, or used in conjunction with vegetation surveys to study the occurrence and abundance of pathways across the continent. This dataset will be updated as TERN's plot network expands and new information becomes available.

Using the National Mental Health Service Planning Framework to support an integrated approach to regional mental health planning in Queensland, Australia.

Aust J Prim Health 2021 Mar 3. Epub 2021 Mar 3.

Regional integrated service planning has been identified as a key priority for improving the mental health system in Australia. The National Mental Health Service Planning Framework (NMHSPF) is an integrated planning tool that estimates the resources required to deliver the optimal mix of mental health services to a population. In 2016, Queensland Health commissioned a trial application of the NMHSPF for joint mental health planning between a Primary Health Network (PHN) and the corresponding state Hospital and Health Services (HHSs) in a regional area. The aim of this work was to collaborate with stakeholders from each organisation to collect available data on the delivery and resources of existing mental health services in the region and compare these to NMHSPF estimates to identify potential priority areas for planning. This paper provides mental health planners with an exemplar model for using the NMHSPF to support integrated planning at the regional level and describes the barriers, facilitators and key outcomes of this work.

COVID-19 infection in patients with intestinal failure: UK experience.

JPEN J Parenter Enteral Nutr 2021 08 6;45(6):1369-1375. Epub 2021 May 6.

Intestinal Failure Unit, Salford Royal Hospital, Salford, UK.

Background: The direct effect of the coronavirus disease 2019 (COVID-19) pandemic on patients with intestinal failure (IF) has not been described.

Methods: We conducted a nationwide study of UK IF centers to evaluate the infection rates, presentations, and outcomes in patients with types 2 and 3 IF.

Results: A total of 45 patients with IF contracted COVID-19 between March and August 2020; this included 26 of 2191 (1.2%) home parenteral nutrition (HPN)-dependent adults and 19 of 298 (6.4%) adults hospitalized with type 2 IF. The proportion of patients receiving nursing care for HPN administration was higher in those with community-acquired COVID-19 (66.7%) than the proportion in the entire HPN cohort (26.1%; P < .01). Two HPN-dependent and 1 hospitalized patient with type 2 IF died as a direct consequence of the virus (6.7% of 45 patients with types 2 or 3 infected).

Conclusion: This is the first study to describe the outcomes of COVID-19 in a large cohort of patients requiring long-term PN. Methods to reduce hospital and community nosocomial spread would likely be beneficial.

Components of leaf-trait variation along environmental gradients.

New Phytol 2020 10 24;228(1):82-94. Epub 2020 Apr 24.

School of Biological Sciences, University of Adelaide, North Terrace, Adelaide, SA, 5005, Australia.

Leaf area (LA), mass per area (LMA), nitrogen per unit area (N ) and the leaf-internal to ambient CO ratio (χ) are fundamental traits for plant functional ecology and vegetation modelling. Here we aimed to assess how their variation, within and between species, tracks environmental gradients. Measurements were made on 705 species from 116 sites within a broad north-south transect from tropical to temperate Australia. Trait responses to environment were quantified using multiple regression; within- and between-species responses were compared using analysis of covariance and trait-gradient analysis. Leaf area, the leaf economics spectrum (indexed by LMA and N ) and χ (from stable carbon isotope ratios) varied almost independently among species. Across sites, however, χ and LA increased with mean growing-season temperature (mGDD ) and decreased with vapour pressure deficit (mVPD ) and soil pH. LMA and N showed the reverse pattern. Climate responses agreed with expectations based on optimality principles. Within-species variability contributed < 10% to geographical variation in LA but > 90% for χ, with LMA and N intermediate. These findings support the hypothesis that acclimation within individuals, adaptation within species and selection among species combine to create predictable relationships between traits and environment. However, the contribution of acclimation/adaptation vs species selection differs among traits.

Review of services to inform clinical frameworks for adolescents and young adults with severe, persistent and complex mental illness.

Clin Child Psychol Psychiatry 2019 Jul 28;24(3):503-528. Epub 2019 Feb 28.

1 School of Public Health, Faculty of Medicine, The University of Queensland, Australia.

Objective: Severe, persistent and complex mental illness (SPCMI) affects a small proportion of young people but is associated with severe disability and a large burden on families and health services. This article identifies and describes service models for adolescents and young adults with SPCMI.

Methods: A systematic search was conducted for services for young people aged 12-25 years with SPCMI. The review sought service models providing extended care and/or multidisciplinary services to meet the complex and long-term needs of this population.

Results: A total of 43 sources were identified. Evidence of effectiveness was found for both community- and bed-based services. Specific components suggested as important in service delivery included care provided by multidisciplinary teams, consumer and family involvement in care planning, intensive case management and service integration through the continuum of care.

Conclusion: Clinical frameworks for this population must incorporate effective community care integrated with inpatient treatment of short duration. Frameworks require consumer and family-centred care with flexibility to support progression through developmental stages and tasks while addressing issues related to risk management, fluctuation in illness severity and stages of recovery. A continuum of care is necessary to meet the needs that arise from SPCMI in adolescents and young adults.
