RESUMO

BACKGROUND: Tasmania has the most rurally and remotely dispersed population of young people in Australia with high rates of youth experiencing mental ill health and socioeconomic disadvantage. Standard descriptions of mental healthcare provision are necessary for evidence-informed mental healthcare policy, planning and implementation. This systematic scoping study aimed to: (1) map and describe the characteristics of community-based youth mental health services (including substance-use) for young people in Tasmania, Australia and (2) identify gaps in service accessibility and provision. METHODS: A list of eligible services was developed through a systematic search and consultation with key stakeholders. Data were collected from a representative from each eligible service via an interview or online survey. A standardised framework was used to classify, describe and map services. Thematic analysis was used to analyse service providers' perceived gaps to service access and provision. RESULTS: Twenty-eight community-based mental health services for youth were identified, predominantly located in the major city of Tasmania's three service regions. Service gaps include the 'missing middle', lack of integrated supports and limited service capacity. CONCLUSIONS: The findings highlight the limited availability, accessibility and capacity of youth mental health services across Tasmania. Recommendations focus on increasing accessibility of rural/regional supports, provision of assertive outreach, psychosocial support, integrated care and strengthening the rural mental health workforce. These findings may inform the (re)design/(re)development of community-based youth mental health services in Tasmania. The findings may also guide evidence-informed mental health service planning, decision-making, development and implementation of integrated models of youth mental health care across Australia.

RESUMO

BACKGROUND: Tasmania, the smallest state by population in Australia, has a comprehensive tobacco control mass media campaign program that includes traditional (eg, television) and "new" channels (eg, social media), run by Quit Tasmania. The campaign targets adult smokers, in particular men aged 18-44 years, and people from low socioeconomic areas. OBJECTIVE: This study assesses the impact of the 2019-2021 campaign program on smokers' awareness of the campaign program, use of Quitline, and smoking-related intentions and behaviors. METHODS: We used a tracking survey (conducted 8 times per year, immediately following a burst of campaign activity) to assess campaign recall and recognition, intentions to quit, and behavioral actions taken in response to the campaigns. The sample size was approximately 125 participants at each survey wave, giving a total sample size of 2000 participants over the 2 years. We merged these data with metrics including television target audience rating points, digital and Facebook (Meta) analytics, and Quitline activity data, and conducted regression and time-series modeling. RESULTS: Over the evaluation period, unprompted recall of any Quit Tasmania campaign was 18%, while prompted recognition of the most recent campaign was 50%. Over half (52%) of those who recognized a Quit Tasmania campaign reported that they had performed or considered a quitting-related behavioral action in response to the campaign. In the regression analyses, we found having different creatives within a single campaign burst was associated with higher campaign recall and recognition and an increase in the strength of behavioral actions taken. Higher target audience rating points were associated with higher campaign recall (but not recognition) and an increase in quit intentions, but not an increase in behavioral actions taken. Higher Facebook advertisement reach was associated with lower recall among survey participants, but recognition was higher when digital channels were used. The time-series analyses showed no systematic trends in Quitline activity over the evaluation period, but Quitline activity was higher when Facebook reach and advertisement spending were higher. CONCLUSIONS: Our evaluation suggests that a variety of creatives should be used simultaneously and supports the continued use of traditional broadcast channels, including television. However, the impact of television on awareness and behavior may be weakening. Future campaign evaluations should closely monitor the effectiveness of television as a result. We are also one of the first studies to explicitly examine the impact of digital and social media, finding some evidence that they influence quitting-related outcomes. While this evidence is promising for campaign implementation, future evaluations should consider adopting rigorous methods to further investigate this relationship.

RESUMO

A new genus and species of myxomycete, Tasmaniomyxa umbilicata, is described based on numerous observations in Tasmania and additional records from southeastern Australia and New Zealand. The new taxon is characterized by an unusual combination of characters from two families: Lamprodermataceae and Didymiaceae. With Lamprodermataceae the species shares limeless sporocarps, a shining membranous peridium, an epihypothallic stalk, and a cylindrical columella. Like Didymiaceae, it has a soft, flaccid, sparsely branched capillitium, with rough tubular threads that contain fusiform nodes and are firmly connected to the peridium. Other characters of T. umbilicata that also occur in many Didymiaceae are the peridium dehiscing into petaloid lobes, the yellow, motile plasmodium, and the spores ornamented with larger, grouped and smaller, scattered warts. The transitional position of the new taxon is reflected by a three-gene phylogeny, which places T. umbilicata at the base of the branch of all lime-containing Physarales, thus justifying its description as a monotypic genus.

RESUMO

OBJECTIVE: To explore women's oral health experiences and barriers to dental care and identify potential strategies to improve oral health during pregnancy. METHODS: A qualitative descriptive study design was used. Purposively elected antepartum and postpartum women ≥18 years of age from Tasmania, Australia, were recruited using maximum variation sampling. Semi-structured interviews were conducted, and all qualitative data were analysed using an inductive thematic approach. RESULTS: Fifteen women were interviewed with a mean ± SD age of 32.3 ± 4.5 years. Three key themes were generated from the data that described women's perceived changes in their oral health during pregnancy; barriers to oral health care during and after pregnancy; and perceived strategies to improve access to care. Most women acknowledged the importance of maintaining good oral health but reported a decline in their oral health status during pregnancy. Women also identified several barriers to dental care, including treatment costs, competing maternal priorities, limited oral health knowledge and negative perceptions towards dentistry. The provision of preventative oral health care by ANC providers was also limited. Community awareness, patient education resources and assessment tools could support the promotion of oral health care. Women also perceived that interprofessional collaboration between antenatal and dental providers played a key role in promoting oral health. CONCLUSION: This study explored women's varied oral health experiences and perceptions during pregnancy and highlighted critical barriers and enablers to dental care. Policy-level strategies that promote interprofessional collaboration between antenatal and dental providers and expand dental care access are suggested to overcome barriers to oral health for women during pregnancy.

RESUMO

OBJECTIVES: People living with chronic obstructive pulmonary disease (COPD) in regional communities experience a higher disease burden and have poorer access to support services. This study sought to investigate the acceptability of a peer-led self-management program (SMP) in regional Tasmania, Australia. METHODS: This descriptive qualitative study, underpinned by interpretivism used semi-structured one-to-one interviews to gather data to explore COPD patients' views of peer-led SMPs. Purposeful sampling recruited a sample of 8 women and 2 men. Data was analysed using a thematic approach. RESULTS: The three final themes, 'Normality and Living with the disease', a 'Platform for sharing' and 'Communication mismatch' suggest that peer-led SMPs could offer an opportunity to share experiences. The themes also suggest that COPD often manifested as a deviation from 'normal life'. Communication was often felt to be ambiguous leading to tension between the health experts and people living with the condition. DISCUSSION: Peer-led SMP has the potential to provide the much-needed support for people living with COPD in regional communities. This will ensure that they are empowered to live with the condition with dignity and respect. Benefits of exchanging ideas and socialisation should not be ignored and may enhance sustainability of SMPs.

RESUMO

BACKGROUND: The COVID-19 pandemic had a significant impact on community mental health globally and widened pre-existing health and social inequities. Tasmania, Australia has one of the highest rates of mental ill health and socioeconomic disadvantage in the country. Whilst Tasmania experienced a delayed and reduced physical presence of COVID-19 compared to other states and territories, mental health impacts remain. It is necessary to understand such impacts to inform policy, practice, and recommendations to enhance the mental health service sector and prevent future mental health burden. This qualitative study aimed to explore expert mental health stakeholders' perspectives of the impact of COVID-19 on: (1) the mental health of people living in Tasmania, and (2) mental health services. METHOD: Semi-structured interviews with 12 expert mental health stakeholders across Tasmania were conducted. This sample was well-positioned to comment on the impact of COVID-19 on community mental health and provide recommendations to enhance the sector. Interviews were thematically analysed. RESULTS: Three subthemes exploring the COVID-19 impact on mental health were included: (1) anxiety, distress, and isolation; (2) varying presentations across age groups; and (3) increased complexity. Four key themes capturing the COVID-19 impact on mental health services were identified: (1) transition to telehealth; (2) increased service demand; (3) spotlight on service gaps; and (4) local workforce shortages. CONCLUSIONS: The pandemic has highlighted existing gaps across the community mental health service sector, and exacerbated existing psychosocial/structural stressors resulting in increased presentations and complexity of mental illness among the community, particularly for youth. Existing treatment gaps and inequities in service access, engagement, and mental health outcomes will persist if not addressed. Recommendations have been provided to inform community mental health service planning, policy, design, access, and provision, and improve wellbeing.

RESUMO

Invasive species are predicted to adjust their morphological, physiological and life-history traits to adapt to their non-native environments. Although a loss of genetic variation during invasion may restrict local adaptation, introduced species often thrive in novel environments. Despite being founded by just a few individuals, Bombus terrestris (Hymenoptera: Apidae) has in less than 30 years successfully spread across the island of Tasmania (Australia), becoming abundant and competitive with native pollinators. We use RADseq to investigate what neutral and adaptive genetic processes associated with environmental and morphological variation allow B. terrestris to thrive as an invasive species in Tasmania. Given the widespread abundance of B. terrestris, we expected little genetic structure across Tasmania and weak signatures of environmental and morphological selection. We found high gene flow with low genetic diversity, although with significant isolation-by-distance and spatial variation in effective migration rates. Restricted migration was evident across the mid-central region of Tasmania, corresponding to higher elevations, pastural land, low wind speeds and low precipitation seasonality. Tajima's D indicated a recent population expansion extending from the south to the north of the island. Selection signatures were found for loci in relation to precipitation, wind speed and wing loading. Candidate loci were annotated to genes with functions related to cuticle water retention and insect flight muscle stability. Understanding how a genetically impoverished invasive bumblebee has rapidly adapted to a novel island environment provides further understanding about the evolutionary processes that determine successful insect invasions, and the potential for invasive hymenopteran pollinators to spread globally.

RESUMO

Mycomya quadrimaculata sp. nov. is described from specimens collected in southeast Australia, Tasmania, and New Zealand. A key and type photographs of known Australian and New Zealand Mycomya species are provided. The relative abundance, observed distribution, and morphological affinities of the new species suggests that it is adventive and a recent introduction to New Zealand. Wing characters indicate that the new species is most closely aligned with a subgroup of the Australian Mycomya fauna.

RESUMO

INTRODUCTION: Two universities run a collaborative Medical Radiation Science program where students undertake study in Tasmania before transferring to a partner university in another state to complete their program. This study assessed rates and predictors of graduate radiographers, radiation therapists and nuclear medicine technologists (collectively classified as medical radiation practitioners according to AHPRA [https://www.medicalradiationpracticeboard.gov.au/About.aspx; ahpra.gov.au/registration/registers] contemporary classification) returning to Tasmania and rural locations to practice. METHODS: A cross-sectional 22-item online survey including open-ended questions was administered via Facebook. Rates of graduates working in Tasmania and rural locations, work satisfaction, and program efficacy were assessed. Logistic regression was used to assess predictors of working in Tasmania and rural locations. RESULTS: 58 Facebook members from a total of 87 program graduates were invited to participate. Of these, 21 responded. Thirteen (62.0%) were currently working in Tasmania, of which the majority practised in regional (MMM2) areas. Most (90.5%) reported that they were happy at work, with all participants reporting the course prepared them well or very well for their first professional jobs. 71.4% stated that the provision of the first 2 years of the course in their home state influenced their decision to study medical radiation science. Being born in a rural region (MMM > 2) was a predictor for working in Tasmania (OR = 3.5) and rural locations (OR = 1.77). Males were twice as likely to work in Tasmania (OR = 2.3) and more rural locations (OR = 2.0). CONCLUSIONS: Collaboration is beneficial in producing professionals in regions with smaller enrolments limit the ability to grow their own graduates independently. Interuniversity collaborative models are recommended for other rural regions to meet local health workforce needs.

RESUMO

INTRODUCTION: Clinical radiology is a popular career. However, academic radiology in Australia and New Zealand (ANZ) has not traditionally been a strength of the specialty which has a focus on clinical medicine and has been influenced by corporatisation of the specialty. The aim of this study was to review the source(s) of radiologist-led research in Australia and New Zealand, to identify areas of relative deficiency and propose plans to improve research output. METHODS: A manual search was performed of all manuscripts in seven popular ANZ journals, where the corresponding or senior author was a radiologist. Publications between January 2017 and April 2022 were included. RESULTS: There were 285 manuscripts from ANZ radiologists during the study period. This equates to 10.7 manuscripts per 100 radiologists based on RANZCR census data. Radiologists in Northern Territory, Victoria, Western Australia, South Australia and the Australian Capital Territory all produced manuscripts above the corrected mean incidence rate of 10.7 manuscripts per 100 radiologists. However, locations including Tasmania, New South Wales, New Zealand and Queensland were below the mean. The majority of manuscripts arose from public teaching hospitals with accredited trainees (86%), and there were a higher proportion of manuscripts published by female radiologists (11.5 compared to 10.4 per 100 radiologists). CONCLUSION: Radiologists in ANZ are academically active; however, interventions aimed at increasing output could be targeted at certain locations and/or areas within a busy private sector. Time, culture, infrastructure and research support are vital, but personal motivation is also extremely important.

RESUMO

The establishment of sustainable, low-intensity fire regimes is a pressing global challenge given escalating risk of wildfire driven by climate change. Globally, colonialism and industrialisation have disrupted traditional fire management, such as Indigenous patch burning and silvo-pastoral practices, leading to substantial build-up of fuel and increased fire risk. The disruption of fire regimes in southeastern Tasmania has led to dense even-aged regrowth in wet forests that are prone to crown fires, and dense Allocasuarina-dominated understoreys in dry forests that burn at high intensities. Here, we investigated the effectiveness of several fire management interventions at reducing fire risk. These interventions involved prescribed burning or mechanical understorey removal techniques. We focused on wet and dry Eucalyptus-dominated sclerophyll forests on the slopes of kunanyi/Mt. Wellington in Hobart, Tasmania, Australia. We modelled potential fire behaviour in these treated wet and dry forests using fire behaviour equations based on measurements of fuel load, vegetation structure, understorey microclimate and regional meteorological data. We found that (a) fuel treatments were effective in wet and dry forests in reducing fuel load, though each targeted different layers, (b) both mechanical treatments and prescribed burning resulted in slightly drier, and hence more fire prone understorey microclimate, and (c) all treatments reduced predicted subsequent fire severity by roughly 2-4 fold. Our results highlight the importance of reducing fuel loads, even though fuel treatments make forest microclimates drier, and hence fuel more flammable. Our finding of the effectiveness of mechanical treatments in lowering fire risk enables managers to reduce fuels without the risk of uncontrolled fires and smoke pollution that is associated with prescribed burning. Understanding the economic and ecological costs and benefits of mechanic treatment compared to prescribed burning requires further research.

RESUMO

OBJECTIVE: This article aims to examine cross-sectional associations and assess temporal trends in keratinocyte carcinoma (KC) incidence by area-level socioeconomic status (SES) and geographic remoteness in Tasmania, Australia. METHODS: KCs-basal cell carcinoma (BCC) and cutaneous squamous cell carcinoma (SCC)-registered by the Tasmanian Cancer Registry were assigned to area-level SES and remoteness area. Incidence rate ratios (2014-2018) were estimated using Poisson regression. Average annual percentage changes (2001-2018) were estimated using the Joinpoint Regression Program. RESULTS: BCC incidence increased with increasing area-level advantage (p value for trend <0.001), but no trend was found for SCC. SCC incidence was higher in rural than urban areas (p value <0.001), and BCC incidence was slightly lower in rural than urban areas for males (p value = 0.026), but not for females (p value = 0.381). BCC and SCC incidence increased between 2001 and the mid-2010s, when it peaked across most areas. CONCLUSIONS: Associations were found between BCC and higher area-level SES, and between SCC and geographic remoteness. The findings suggest differences in sun exposure behaviours, skin cancer awareness and access to services, or ascertainment bias. IMPLICATIONS FOR PUBLIC HEALTH: Efforts to control and deliver KC services in Tasmania should consider targeting populations with specific area-level characteristics.

RESUMO

OBJECTIVE: This study aimed to investigate the trends and associations of maternal characteristics and birthweight among Indigenous and non-Indigenous infants. STUDY DESIGN: This was a retrospective population-based study. METHODS: Fourteen years (2005-2018) of birthweight and perinatal health data of live-born singletons and their mothers obtained from the Tasmanian Data Linkage Unit were used to assess the trends and associations between maternal characteristics and infant birthweight using regression modelling. RESULTS: Compared with non-Indigenous mothers (n = 76,750), Indigenous mothers (n = 3805) had a significantly higher prevalence of risk factors during the 14-year period. Although the prevalence of prepregnancy obesity and gestational diabetes mellitus (GDM) markedly increased in both groups, the rate of increase was higher (P < 0.001) for Indigenous than non-Indigenous mothers. Smoking, alcohol consumption and illegal drug use during pregnancy reduced over the years, and there was no significant difference in the rate of reduction between the groups. Large-for-gestational-age (LGA) births increased while small-for-gestational-age (SGA) births decreased in both groups over time. In addition, high birthweight (HBW) births decreased while low birthweight (LBW) births increased. The rates of increase in LGA and LBW births and the rates of decrease in SGA and HBW births were significantly higher in Indigenous mothers compared with non-Indigenous mothers (P < 0.001 for all). The association between Indigenous ethnicity and LBW and SGA births weakened after adjusting for other confounding maternal and perinatal variables. LBW and SGA were positively associated with Indigenous ethnicity, age <18 years, smoking, alcohol consumption and illegal drug use, pre-eclampsia, underweight prepregnancy body mass index and low socio-economic status. Women with higher parity, pre-existing diabetes and prepregnancy overweight or obesity were more likely to give birth to an infant with HBW or LGA. CONCLUSIONS: The prevalence of risk factors for abnormal birthweight is higher among Tasmanian Indigenous mothers, contributing to a gap in birthweight outcomes between Indigenous and non-Indigenous infants. The dramatic increase in prepregnancy obesity and GDM in both groups highlight the importance of screening and management of GDM during pregnancy. Comprehensive programmes co-designed and co-managed in consultation with Indigenous people are needed to support healthy lifestyle choices among Indigenous women to address the barriers to individuals adopting behaviour change and to help close the health outcomes-related gap between Indigenous and non-Indigenous mothers and infants.

RESUMO

INTRODUCTION: This study aimed to develop a standard process and checklist for technical investigation of hookah diving equipment and apply it to Tasmanian hookah fatality investigations from the last 25 years. METHODS: A literature search was undertaken to identify technical reports and equipment investigations associated with diving accidents. The information was assimilated to create a process and checklist for specifically assessing the hookah apparatus. The checklist was then applied in a gap analysis of Tasmanian hookah diving fatality technical reports from 1995 to 2019. RESULTS: As no papers specifically describing technical evaluation of hookah equipment were identified, references evaluating scuba equipment were used to create a hookah technical assessment process incorporating unique features of the hookah. Features included: owner responsibility for air quality; maintenance, function; exhaust proximity to air intake; reservoir volume; output non-return valves; line pressure; sufficiency of supply; entanglement; hose severance risk; gas supply failure and hosing attachment to the diver. Seven hookah diving deaths occurred in Tasmania (1995-2019) of which three had documented technical assessment. Gap analysis identified inconsistent structure between reports with variability in the case descriptors. Missing technical data included: overview of the hookah systems; accessories; weights; how the apparatus was worn by the diver; compressor suitability; assessment of hookah function; breathing gas output and exhaust position relative to air intake. CONCLUSIONS: The study demonstrated a need to standardise technical reporting of hookah equipment after diving accidents. The checklist generated may serve as a resource for future hookah assessments and inform strategies for preventing future hookah accidents.

RESUMO

There is a growing recognition of the harmful effects of lead exposure on avian and mammalian scavengers. This can lead to both lethal and non-lethal effects which may negatively impact wildlife populations. Our objective was to assess medium-term lead exposure in wild Tasmanian devils (Sarcophilus harrisii). Frozen liver samples (n = 41), opportunistically collected in 2017-2022, were analysed using inductively coupled plasma mass spectrometry (ICP-MS) to determine liver lead concentrations. These results were then used to calculate the proportion of animals with elevated lead levels (>5 mg/kg dry weight) and examine the role of explanatory variables that may have influenced the results. The majority of samples analysed were from the south-east corner of Tasmania, within 50 km of Hobart. No Tasmanian devil samples were found to have elevated lead levels. The median liver lead concentration was 0.17 mg/kg (range 0.05-1.32 mg/kg). Female devils were found to have significantly higher liver lead concentrations than males (P = 0.013), which was likely related to lactation, but other variables (age, location, body mass) were not significant. These results suggest that wild Tasmanian devil populations currently show minimal medium-term evidence of exposure to lead pollution, although samples were concentrated in peri-urban areas. The results provide a baseline level which can be used to assess the impact of any future changes in lead use in Tasmania. Furthermore, these data can be used as a comparison for lead exposure studies in other mammalian scavengers, including other carnivorous marsupial species.

RESUMO

Objective To estimate the risk of an emergency department (ED)/inpatient visit due to complications in people with diabetes and compare them to their non-diabetes counterparts. Methods This matched retrospective cohort study used a linked dataset in Tasmania, Australia for the 2004-17 period. People with diabetes (n = 45 378) were matched on age, sex and geographical regions with people without diabetes (n = 90 756) based on propensity score matching. The risk of an ED/inpatient visit related to each complication was estimated using negative binomial regression. Results In people with diabetes, the combined ED and admission rates per 10 000 person-years were considerable, especially for macrovascular complications (ranging from 31.8 (lower extremity amputation) to 205.2 (heart failure)). The adjusted incidence rate ratios of ED/inpatient visits were: retinopathy 59.1 (confidence interval 25.8, 135.7), lower extremity amputation 11.1 (8.8, 14.1), foot ulcer/gangrene 9.5 (8.1, 11.2), nephropathy 7.4 (5.4, 10.1), dialysis 6.5 (3.8, 10.9), transplant 6.3 (2.2, 17.8), vitreous haemorrhage 6.0 (3.7, 9.8), fatal myocardial infarction 3.4 (2.3, 5.1), kidney failure 3.3 (2.3, 4.5), heart failure 2.9 (2.7, 3.1), angina pectoris 2.1 (2.0, 2.3), ischaemic heart disease 2.1 (1.9, 2.3), neuropathy 1.9 (1.7, 2.0), non-fatal myocardial infarction 1.7 (1.6, 1.8), blindness/low vision 1.4 (0.8, 2.5), non-fatal stroke 1.4 (1.3, 1.6), fatal stroke 1.3 (0.9, 2.1) and transient ischaemic attack 1.1 (1.0, 1.2). Conclusions Our results demonstrated the high demand on hospital services due to diabetes complications (especially macrovascular complications) and highlighted the importance of preventing and properly managing microvascular complications. These findings will support future resource allocation to reduce the increasing burden of diabetes in Australia.

RESUMO

OBJECTIVE: To describe the first outbreak of Barmah Forest virus (BFv) in Tasmania and identify potential vectors for BFv in Tasmania. METHODS: A retrospective descriptive study of BFv notifications in the Tasmanian Notifiable Diseases Database (TNDD) was conducted. Adult mosquitoes were sampled from areas near outbreak cases and pooled samples were tested for BFv. RESULTS: 27 cases of confirmed BFv were recorded in the TNDD between 12 March 1999 and 30 June 2019. Nine cases were recorded between 21 January and 10 May 2019 that were acquired in Tasmania, with eight included in this confirmed outbreak. All outbreak cases resided in or travelled to locations in the Break O'Day Local Government Area and reported no recent interstate travel. No virus was detected in pooled mosquito samples. CONCLUSIONS: This is Tasmania's first confirmed outbreak of BFv. Known BFv vector species were identified in both saltmarsh and urban-fringe brackish saltmarsh larval habitats. BFv was not detected from pooled mosquito samples. IMPLICATIONS FOR PUBLIC HEALTH: Clinicians should consider BFv as a possible diagnosis for presentations with fever and arthritis, and potential mosquito exposure in Tasmania. These findings will guide broadening of prevention-focussed public health messaging.
