Characteristics of people diagnosed with dementia vs lung cancer and cardiovascular disease at commencement of community palliative care: a population-based study.

BACKGROUND: Most people diagnosed with dementia live and die in community settings. This study aimed to: (i) describe the palliative care needs of patients with dementia at commencement of community palliative care; (ii) compare palliative care needs between patients with dementia and those with lung cancer and cardiovascular disease (CVD). METHODS: This is a population-based descriptive study that involved 8,727, 7,539 and 25,279 patients who accessed community palliative care across Australia principally because of dementia, CVD and lung cancer. Patients' functional abilities, symptom burden and clinical condition were assessed at commencement of community alliative care using five validated instruments: Resource Utilisation Groups-Activities of Daily Living, Australia-modified Karnofsky Performance Status, Symptoms Assessment Scale, Palliative Care Problem Severity Score and Palliative Care Phase. We fitted ordinal logistic regression models to examine the differences in these assessments for dementia versus CVD and lung cancer, respectively. RESULTS: Overall, patients with dementia generally had low levels of distress from symptoms but poor functional problems. Compared to the other two diagnostic groups, palliative care for dementia was often initiated later and with shorter contacts. Also, patients with dementia presented with poorer functional performance (adjusted OR (aOR) = 4.02, Confidence Interval (CI): 3.68 - 4.38 for dementia vs CVD; aOR = 17.59, CI: 15.92 - 19.44 for dementia vs lung cancer) and dependency (aOR = 5.68, CI: 5.28 - 6.12 for dementia vs CVD; aOR = 24.97, CI: 22.77 - 27.39 for dementia vs lung cancer), but experienced lower levels of distress and problem severity for the majority of symptoms. CONCLUSION: Community palliative care is often an ideal care option for many patients, particularly for those with dementia. We call for expansion of the palliative care workforce and options for home care support to optimize accessibility of community palliative care for dementia.

Contextualising Experiences of Co-Occurring Mental Ill-Health and Substance Use Among Trans, Non-Binary, and Gender Diverse Young People: Implications for Tailored Harm Reduction Approaches.

Though significant research highlights higher rates of mental ill-health and substance use among trans, non-binary and gender diverse (henceforth 'trans') young people, little research has considered patterns, contextual characteristics, and correlates of co-occurring experiences of mental ill-health and substance use among trans young people. Using data from the Trans Pathways study, we used prevalence ratios and age- and gender-adjusted logistic regression models to examine prevalence and differences of co-occurring substance use (past six-month cigarette use, alcohol use, and other drug use) and contextual characteristics of substance use (past six-month solitary alcohol and/or drug use, substance use for coping) by mental ill-health (depression disorder, anxiety disorder, past 12-month self-harm thoughts and behaviours, suicidal thoughts, planning, and attempt/s). Age- and gender-adjusted models assessed associations between co-occurring depressive and anxiety disorders and recent cigarette, alcohol, and other drug use (six co-occurring items total) and 18 interpersonal stressors. Significantly increased odds of smoking or recent use of cannabis or sedatives was observed among trans young people reporting depressive disorder, anxiety disorder (aORs ranging 1.8-3.1). Trans young people who reported recent smoking or use of cannabis, inhalants, or sedatives, had 40% to 80% reduced odds of past 12-month self-harm thoughts, self-harm behaviours, suicidal thoughts, and suicide attempt/s (aORs ranging 0.2-0.6). On the other hand, solitary alcohol and/or other drug use and substance use for coping was significantly associated with increased odds of all mental ill-health outcomes. Issues with school, secure housing, and intimate partner abuse were the most robust correlates of co-occurring mental ill-health and substance use. Trans young people using substances, especially cigarettes, cannabis, and sedatives, often so do with co-occurring experiences of depression and anxiety though limited substance use in more 'social' contexts may confer benefits for preventing self-harm and suicide thoughts and behaviours. Continued research in partnership with trans young people is warranted to conceptualise more nuanced and precise conceptual parameters of trans-affirming substance use harm reduction approaches.

Association of allergic diseases and epilepsy with risk of glioma, meningioma and acoustic neuroma: results from the INTERPHONE international case-control study.

We investigated the association of allergic diseases and epilepsy with risk of brain tumours, in Interphone, a 13-country case-control study. Data were obtained from 2693 glioma cases, 2396 meningioma cases, and 1102 acoustic neuroma cases and their 6321 controls. Conditional logistic regression models were used to estimate pooled odds ratios (ORs) and their respective 95% confidence intervals (CIs), adjusted for education and time at interview. Reduced ORs were observed for glioma in relation to physician-diagnosed asthma (OR = 0.73; CI 0.58-0.92), hay fever (OR 0.72; CI 0.61-0.86), and eczema (OR 0.78, CI 0.64-0.94), but not for meningioma or acoustic neuroma. Previous diagnosis of epilepsy was associated with an increased OR for glioma (2.94; CI 1.87-4.63) and for meningioma (2.12; CI 1.27-3.56), but not for acoustic neuroma. This large-scale case-control study adds to the growing evidence that people with allergies have a lower risk of developing glioma, but not meningioma or acoustic neuroma. It also supports clinical observations of epilepsy prior to the diagnosis of glioma and meningioma.

Symptom trajectories for palliative care inpatients with and without hyperactive delirium in the last week of life.

AIMS: Hyperactive delirium (HD) is a common and distressing symptom among palliative care patients. This study aimed to describe the characteristics of HD and associated symptoms among palliative care inpatients and evaluate relationships between HD development and symptom trajectories in this population. DESIGN: A retrospective study was conducted. METHODS: A retrospective review of medical records was conducted for all patients who died in a large Australian specialist palliative care unit between 1 January and 31 December 2019. Patients were assessed daily using the Symptoms Assessment Scale (SAS) and Palliative Care Problem Severity Scale (PCPSS). Multilevel models were used to estimate the differences in symptoms trajectories in the last 7 days of life between the two groups. RESULTS: Of the 501 included patients, 64.5% (323) had an episode of HD. For 30% (95) of patients, HD occurred prior to admission. Compared with patients without HD, those with HD had significantly higher odds ratios (ORs) for four of the seven SAS symptoms (sleep problems, appetite, fatigue and pain; OR range: 1.94-4.48, p < .05), and all four PCPSS items (OR range: 2.00-3.00, p < .05) in the last week of life. CONCLUSIONS: Palliative care inpatients commonly experience HD in their last week of life. There are higher levels of symptom distress, complexity, psychological concerns and family/carer concerns among patients with HD compared with those without HD. IMPACT: The high prevalence of HD, and its association with higher levels of symptom distress, highlights the importance of routine screening and optimal management for HD among palliative care patients. Given the widely recognized challenges facing palliative care professionals in assessment and management of delirium, provision of relevant training among these professionals is recommended.

Palliative care needs and utilisation of different specialist services in the last days of life for people with lung cancer.

OBJECTIVES: To (a) compare palliative care needs of lung cancer patients on their final admission to community-based and inpatient palliative care services; and (b) explore whether and how these care needs affect their utilisation of different palliative care services in the last days of life. METHODS: Descriptive study involving 17,816 lung cancer patients who received the last episode of palliative care from specialist services and died between 1 January 2013 and 31 December 2018. RESULTS: Both groups of patients admitted to community-based and inpatient palliative care services generally experienced relatively low levels of symptom distress, but high levels of functional impairment and dependency. "Unstable" versus "stable" palliative care phase (Odds ratio = 11.66; 95% Confidence Interval: 9.55-14.24), poorer functional outcomes and severe levels of distress from many symptoms predicted greater likelihood of use of inpatient versus community-based palliative care. CONCLUSIONS: Most inpatient palliative care admissions are not associated with high levels of symptom severity. To extend the period of home care and rate of home death for people with lung cancer, additional investment is required to improve their access to sufficiently skilled palliative care staff, multi-disciplinary teams and 24-hour home support in community settings.

Options and realities for trans and gender diverse young people receiving care in Australia's mental health system: findings from Trans Pathways.

OBJECTIVE: Trans and gender diverse young people experience mental health difficulties self-harm and suicidality at markedly higher rates than the general population, yet they often feel isolated from mental health services. There is little qualitative research on the experiences of trans and gender diverse young people accessing mental health support in Australia. The objective of this study was to comprehensively explore the experiences of trans and gender diverse young people in Australia who have sought mental health support from therapists, counsellors, psychiatrists and/or inpatient care providers. METHODS: We report on findings from the Trans Pathways study, which was a mixed-methods study to evaluate the experiences of trans and gender diverse young people accessing mental health services: specifically, therapy and counselling services, psychiatric services and mental health inpatient services. RESULTS: A total of 859 trans and gender diverse young people aged 14-25 years across Australia completed an anonymous online questionnaire. Therapy and/or counselling services (64.4%) were most frequently sought by trans and gender diverse young people in this study, followed by psychiatric services (43.0%) and mental health inpatient services (12.3%). The findings demonstrated that many mental health professionals lacked expertise in gender diversity, and that trans and gender diverse young people found it difficult to locate mental health professionals who were able to meet their needs in a timely manner. CONCLUSION: These findings indicate that training is necessary for all mental health professionals to improve their knowledge of gender diversity, enhance the support provided to trans and gender diverse young people and help to address the high rates of poor mental health. The findings outlined here provide insight into the areas in which clinicians could optimise their care of trans and gender diverse young people.

"Unless you overdose or something you're not going to get help": What do adolescent experiences reveal about the mental health system in Perth, Western Australia?

ISSUES ADDRESSED: To explore adolescents' experiences of access to and continued use of mental health services, and identify factors influencing their perceived satisfaction with their care. This paper focusses on the role of organisational and policy-level factors in the mental health system. METHOD: Qualitative semi-structured face-to-face interviews with 22 adolescents aged 14-18 years living in Perth, Western Australia. RESULTS: Adolescents identified key policy, systemic and service-based factors which influenced their access to and continued use of mental health services. These were strongly related to the processes of service intake, level of orientation towards person-centred care and adequacy of service resourcing and funding. Areas of concern for adolescents included, complex service intake procedures, suboptimal mental health service environments, lack of client-centred care and the quality of mental health support provided in school settings. CONCLUSIONS: Our research has identified a wide spectrum of factors influencing mental health service access and use amongst adolescents. The findings further support the growing national consensus for major reform to address the mental health needs of this age group. The current strengths within mental health services and the system identified by adolescents need to be supported and extended. SO WHAT?: Although there have been numerous recommendations on ways to improve mental health service access and ongoing engagement for Australian adolescents, a number of the major challenges faced by this high-risk population have shown little improvement. The findings of this research indicate the importance of now moving towards implementing meaningful plans for action.

Associations between negative life experiences and the mental health of trans and gender diverse young people in Australia: findings from Trans Pathways.

BACKGROUND: Trans and gender diverse (TGD) young people worldwide experience high rates of poor mental health; however, these rates were unknown in Australia. In addition, how negative life events affect the mental health of TGD young people has been largely unexplored. METHODS: This paper reports on novel mental health findings of Trans Pathways, the largest study ever conducted in Australia with trans (transgender) and gender diverse young people (N = 859; aged 14-25 years). The study was an anonymous online cross-sectional survey undertaken in 2016. Logistic and linear regression models were used to test associations between mental health outcomes and negative life experiences. RESULTS: TGD young people in Australia experience high levels of mental distress, including self-harming (79.7%), suicidal thoughts (82.4%), and attempting suicide (48.1%). Three in four participants had been diagnosed with depression and/or anxiety (74.6% and 72.2%, respectively). Many TGD young people had been exposed to negative experiences such as peer rejection (89.0%), precarious accommodation (22.0%), bullying (74.0%), and discrimination (68.9%). Most poor mental health outcomes were associated with negative experiences. The strongest associations were found for precarious accommodation and issues within educational settings. For example, participants with a prior suicide attempt were almost six times more likely to have experienced issues with accommodation, including homelessness. CONCLUSIONS: The current results highlight the urgent need for better mental health care and provide insight into areas for targeted mental health interventions. These findings are pertinent for clinicians working with trans young people and wider society.

Defining the ecological and evolutionary drivers of Plasmodium knowlesi transmission within a multi-scale framework.

Plasmodium knowlesi is a zoonotic malaria parasite normally residing in long-tailed and pig-tailed macaques (Macaca fascicularis and Macaca nemestrina, respectively) found throughout Southeast Asia. Recently, knowlesi malaria has become the predominant malaria affecting humans in Malaysian Borneo, being responsible for approximately 70% of reported cases. Largely as a result of anthropogenic land use changes in Borneo, vectors which transmit the parasite, along with macaque hosts, are both now frequently found in disturbed forest habitats, or at the forest fringes, thus having more frequent contact with humans. Having access to human hosts provides the parasite with the opportunity to further its adaption to the human immune system. The ecological drivers of the transmission and spread of P. knowlesi are operating over many different spatial (and, therefore, temporal) scales, from the molecular to the continental. Strategies to prevent and manage zoonoses, such as P. knowlesi malaria require interdisciplinary research exploring the impact of land use change and biodiversity loss on the evolving relationship between parasite, reservoir hosts, vectors, and humans over multiple spatial scales.

End-of-life care in rural general practice: how best to support commitment and meet challenges?

BACKGROUND: Few studies have specifically assessed the scope, nature and challenges of palliative and end-of-life care in rural general practice. These knowledge gaps limit the development of evidence-based policies and services for patients in the last months of life. This study aimed to explore the perspectives of general practitioners (GPs) and other stakeholders on rural GPs' involvement and challenges in providing palliative and end-of-life care in regional Australia. METHODS: A qualitative study involving five focus groups with 26 GPs based in rural/regional Western Australia together with 15 individual telephone interviews with four GPs and 11 other stakeholders involved in end-of-life care across Australia. RESULTS: The rural GPs' central role in end-of-life care was recognized by the majority of participants but multiple challenges were also identified. Some challenges were comparable to those found in urban settings but others were more pronounced, including resource limitations and lack of training. Inappropriate payment models discouraged GPs' involvement in some aspects of end-of-life care, such as case conferences and home visits. Compared to GPs in urban settings, those in rural/regional communities often reported closer doctor-patient relationships and better care integration and collaboration. These positive aspects of care could be further developed to enhance service provision. Our study highlighted the importance of regular interactions with other professionals and patients in providing end-of-life care, but many GPs and other stakeholders found such interactions more challenging than the more "technical" aspects of care. CONCLUSIONS: Rural/regional GPs appear to be disproportionately affected by inappropriate payment models and limited resources, but may benefit from closer doctor-patient relationships and better care integration and collaboration relative to urban GPs. Systematic collection of empirical data on GP management at end-of-life is required to build on these strengths and address the challenges.

Do natural spring waters in Australia and New Zealand affect health? A systematic review.

Therapeutic use of spring waters has a recorded history dating back to at least 1550 BC and includes both bathing in and drinking such waters for their healing properties. In Australia and New Zealand the use of therapeutic spring waters is a much more recent phenomenon, becoming a source of health tourism from the late 1800s. We conducted a systematic review aimed at determining the potential health outcomes relating to exposure to Australian or New Zealand natural spring water. We found only low-level evidence of adverse health outcomes relating to this spring water exposure, including fatalities from hydrogen sulphide poisoning, drowning and primary amoebic meningoencephalitis. We found no studies that investigated the therapeutic use of these waters, compared with similar treatment with other types of water. From the broader literature, recommendations have been made, including fencing potentially harmful spring water, and having signage and media messages to highlight the potential harms from spring water exposure and how to mitigate the risks (e.g. not putting your head under water from geothermal springs). Sound research into the potential health benefits of Australian and New Zealand spring waters could provide an evidence base for the growing wellness tourism industry.

Factors associated with psychological distress amongst outpatient chemotherapy patients: An analysis of depression, anxiety and stress using the DASS-21.

AIM: This study sought to identify clinical, demographic and service-related factors associated with psychological distress amongst outpatient chemotherapy patients. BACKGROUND: Distress in cancer patients leads to increased risk of psychological comorbidity, contributing to sub-optimal treatment adherence and potentially leading to poorer health outcomes. Screening and recognition of distress and risk factors is an important aspect of holistic care within a multidisciplinary team environment. METHODS: Data were obtained via survey and chart review of ambulatory chemotherapy patients at three public tertiary referral hospitals in Perth, Western Australia. The DASS-21 was used to screen for psychological distress. Regression analyses were used to assess the relationship between distress and a range of cancer, socioeconomic and treatment factors. RESULTS: Patients with a Karnofsky Performance Score≤80 (OR 3.8, 95% CI [1.7, 78.7]) and average waiting time (between oncology outpatient appointment and commencement of chemotherapy infusion) >60min (OR 2.4, 95% CI [1.04, 5.5]) were at increased risk of moderate-severe distress. Patients with a household income between $AU 50-75,000 p.a. had a lower risk of distress compared to <$25,000 p.a. (OR 0.05, 95% CI [0.01, 0.52]). On sub-scale analysis, depression and anxiety contributed more to overall distress than the stress subscales. CONCLUSIONS: Performance status, waiting times and household income were key predictors of distress. Findings could assist clinicians to identify higher-risk population subsets that could benefit from targeted screening and additional psychological and social work support. Findings could also assist administrators to consider the contribution of modifiable factors such as waiting times to patient distress.

Effectiveness of the Koorliny Moort out-of-hospital health care program for Aboriginal and Torres Strait Islander children in Western Australia.

OBJECTIVES: To determine whether the Koorliny Moort program could reduce emergency department presentations, hospital admissions and length of stay, and improve attendance at out-of-hospital appointments for Aboriginal and Torres Strait Islander children in Western Australia. DESIGN: Children were enrolled in the program from 1 August 2012. Each child acted as their own control. Evaluation data were collected from 1 August 2010 to 31 July 2014. Occasions of service and person-time in days were compared for each child before and after referral to the program. SETTING AND PARTICIPANTS: Aboriginal children aged 0-16 years residing in three WA regions (Kimberley, Pilbara, Perth metropolitan) who were referred to the Koorliny Moort program. INTERVENTIONS: Partnerships with primary care providers; nurse-led care coordination; and outreach care by paediatricians, nurses and social workers closer to the home of the child. MAIN OUTCOME MEASURES: Emergency department presentations; hospital admissions; length of hospital stay; non-attended appointments. RESULTS: A total of 942 children were referred to the program. There were significant decreases after referral to the program in the incidence of emergency department presentations (incident rate ratio [IRR], 0.47; 95% CI, 0.43-0.53; P < 0.001), of hospitalisation (IRR, 0.70; 95% CI, 0.62-0.79; P < 0.001), and of non-attended appointments (IRR, 0.83; 95% CI, 0.74-0.94; P < 0.001), as well as in the mean length of hospital stay (IRR, 0.23; 95% CI, 0.21-0.25; P < 0.001). CONCLUSIONS: Health-seeking behaviour and health outcomes for Aboriginal children can be improved by engaging Aboriginal families in their health care, providing effective communication between health service providers, and delivering a coordinated program of Aboriginal service provider-led care.

A Bayesian Belief Network for Murray Valley encephalitis virus risk assessment in Western Australia.

BACKGROUND: Murray Valley encephalitis virus (MVEV) is a clinically important virus in Australia responsible for a number of epidemics over the past century. Since there is no vaccine for MVEV, other preventive health measures to curtail its spread must be considered, including the development of predictive risk models and maps to help direct public health interventions. This article aims to support these approaches by presenting a model for assessing MVEV risk in Western Australia (WA). METHODS: A Bayesian Belief Network (BBN) for assessing MVEV risk was developed and used to quantify and map disease risks in WA. The model combined various abiotic, biotic, and anthropogenic factors that might affect the risk of MVEV into a predictive framework, based on the ecology of the major mosquito vector and waterbird hosts of MVEV. It was further refined and tested using retrospective climate data from 4 years (2000, 2003, 2009, and 2011). RESULTS: Implementing the model across WA demonstrated that it could predict locations of human MVEV infection and sentinel animal seroconversion in the 4 years tested with some degree of accuracy. In general, risks are highest in the State's north and lower in the south. The model predicted that short-term climate change, based on the Intergovernmental Panel on Climate Change's A1B emissions scenario, would decrease MVEV risks in summer and autumn, largely due to higher temperatures decreasing vector survival. CONCLUSIONS: To our knowledge, this is the first model to use a BBN to quantify MVEV risks in WA. The models and maps developed here may assist public health agencies in preparing for and managing Murray Valley encephalitis in the future. In its current form, the model is knowledge-driven and based on the analysis of potential risk factors that affect the dynamics of MVEV using retrospective data. Further work and additional testing should be carried out to test its validity in future years.

Atmospheric pitting corrosion of 304L stainless steel: the role of highly concentrated chloride solutions.

The morphology of atmospheric pitting corrosion in 304L stainless steel plate was analysed using MgCl(2) droplets in relation to changes in relative humidity (RH) and chloride deposition density (CDD). It was found that highly reproducible morphologies occur that are distinct at different RH. Pitting at higher concentrations, i.e. lower RH, resulted in satellite pits forming around the perimeter of wide shallow dish regions. At higher RH, these satellite pits did not form and instead spiral attack into the shallow region was observed. Increasing CDD at saturation resulted in a very broad-mouthed pitting attack within the shallow dish region. Large data sets were used to find trends in pit size and morphology in what is essentially a heterogeneous alloy. Electrochemical experiments on 304 stainless steel wires in highly saturated solutions showed that the passive current density increased significantly above 3 M MgCl(2) and the breakdown pitting potential dropped as the concentration increased. It is proposed that the shallow dish regions grow via enhanced dissolution of the passive film, whereas satellite pits and a spiral attack take place with active dissolution of bare metal surfaces.

Variability and consistency in lung inflammatory responses to particles with a geogenic origin.

BACKGROUND AND OBJECTIVE: Particulate matter <10 µm (PM10 ) is well recognized as being an important driver of respiratory health; however, the impact of PM10 of geogenic origin on inflammatory responses in the lung is poorly understood. This study aimed to assess the lung inflammatory response to community sampled geogenic PM10 . METHODS: This was achieved by collecting earth material from two regional communities in Western Australia (Kalgoorlie-Boulder and Newman), extracting the PM10 fraction and exposing mice by intranasal instillation to these particles. The physicochemical characteristics of the particles were assessed and lung inflammatory responses were compared to control particles. The primary outcomes were cellular influx and cytokine production in the lungs of the exposed mice. RESULTS: The physical and chemical characteristics of the PM10 from Kalgoorlie and Newman differed with the latter having a higher concentration of Fe and a larger median diameter. Control particles (2.5 µm polystyrene) caused a significant influx of inflammatory cells (neutrophils) with little production of proinflammatory cytokines. In contrast, the geogenic particles induced the production of MIP-2, IL-6 and a significant influx of neutrophils. Qualitatively, the response following exposure to particles from Kalgoorlie and Newman were consistent; however, the magnitude of the response was substantially higher in the mice exposed to particles from Newman. CONCLUSIONS: The unique physicochemical characteristics of geogenic particles induced a proinflammatory response in the lung. These data suggest that particle composition should be considered when setting community standards for PM exposure, particularly in areas exposed to high geogenic particulate loads.

Antidepressant use and hyperactive delirium at the end of life: retrospective study.

OBJECTIVES: Little is known about the adverse effects associated with antidepressant use in palliative care inpatients imminently approaching death. This study investigates the relationship between antidepressant use and hyperactive delirium in this population. METHODS: This is a retrospective medical record review of patients who died in a metropolitan palliative care unit in Victoria, Australia, during 2019. Generalised estimating equations were used to estimate the association between antidepressant use and presence of hyperactive delirium in the final 2 weeks of life. RESULTS: Of the 501 adult patients who died in the 12-month period, 113 (22.55%) were on at least one antidepressant at the time of admission. Any antidepressant use in the last 14 days of life was significantly associated with the diagnosis of hyperactive delirium (OR 1.48; 95% CI 1.30, 1.68). Patients prescribed antidepressants also experienced longer durations of delirium (3.89 days; SD 4.23) compared with those not taking any antidepressant (2.99 days; SD 3.70) in the final 2 weeks of life. CONCLUSION: Antidepressant use or discontinuation is significantly associated with hyperactive delirium within 14 days of death. Although the causes of delirium are multifactorial and complex, antidepressant use is a potentially modifiable risk factor.

Stages of readiness for advance care planning: Systematic review and meta-analysis of prevalence rates and associated factors.

BACKGROUND: Advance care planning has been widely recommended to respect the medical care preferences of patients in the final stages of life. However, uptake of advance care planning in healthcare settings remains suboptimal. It may be beneficial to take into account individuals' readiness for advance care planning based on the stages to change identified in the Transtheoretical Model. OBJECTIVE: To identify the measurements used to assess readiness of advance care planning based on the Transtheoretical Model, to pool the prevalence of readiness stages, and to summarize the factors affecting people's readiness for advance care planning. DESIGN: Systematic review and meta-analysis. METHODS: We systematically searched the databases of PubMed, EMBASE, The Cochrane Library, CINAHL, and Web of Science for relevant studies from inception to February 2023. A random effects model was used to estimate the pooled prevalence. And a narrative review on the factors associated with stages of readiness was conducted. RESULTS: This meta-analysis included 25 studies involving a total of 4237 individuals. The precontemplation stage was the most commonly identified stage of readiness among advance care planning behaviors (26-72 %). The prevalence of readiness stages for advance care planning varied among different types of behavior. The behavior of "talking to health care proxy/family/loved ones about thoughts on quality versus quantity of life" had the highest level of readiness among all listed behaviors, followed by "talking to health care proxy/family/loved ones about living will", "signing a health care proxy form" and "signing a living will", "signing an advance directive", as well as "talking to doctors about living will". Regarding to influencing factors, a majority of sociodemographic and clinical factors did not show consistent associations with readiness, but some studies did suggest potential links with age, health status, countries, type of assessment, core structures of the Transtheoretical Model, and intervention modalities. CONCLUSIONS: A majority of individuals were unaware of advance care planning. There is an urgent need to promote readiness for such planning. Starting with preliminary activities such as "talking to health care proxy/family/loved ones about thoughts on quality versus quantity of life" can help initiate advance care planning. Better integration of the Transtheoretical Model and interventions into the research of advance care planning readiness are needed. REGISTRATION: Not registered.

An Exploration of LGBTQA+ Young People's Coping Strategies When Navigating Suicidal Thoughts and Behaviors.

LGBTQA+ young people experience suicidal thoughts and behaviors at a much greater rate than their heterosexual and cisgender peers. This study explored firsthand accounts of the coping strategies employed by LGBTQA+ young people when experiencing suicidal thoughts and behaviors. LGBTQA+ young people (N = 27; ages 14-25) in Australia with a history of suicidal thoughts and/or attempts participated in semi-structured interviews. Using reflexive thematic analysis, four major themes were developed: (1) It's about the journey, not the destination, (2) Connecting with others, (3) When I knew better, I coped better, and (4) Doing the best I can with what I have. LGBTQA+ young people reported utilizing a range of coping strategies, however these were limited by a lack of knowledge around mental health, gender and sexuality diversity, and available resources. Experiences of discrimination within support settings and limited access to clinicians with knowledge of sexuality and gender diversity were cited as significant barriers. Interventions to increase mental health literacy in LGBTQA+ young people and improvements to clinician knowledge of sexuality and gender diversity are needed to enhance LGBTQA+ young people's access to effective coping strategies when experiencing suicidal thoughts and behaviors.

Forest Restoration and the Zoonotic Vector Anopheles balabacensis in Sabah, Malaysia.

Anthropogenic changes to forest cover have been linked to an increase in zoonotic diseases. In many areas, natural forests are being replaced with monoculture plantations, such as oil palm, which reduce biodiversity and create a mosaic of landscapes with increased forest edge habitat and an altered micro-climate. These altered conditions may be facilitating the spread of the zoonotic malaria parasite Plasmodium knowlesi in Sabah, on the island of Borneo, through changes to mosquito vector habitat. We conducted a study on mosquito abundance and diversity in four different land uses comprising restored native forest, degraded native forest, an oil palm estate and a eucalyptus plantation, these land uses varying in their vegetation types and structure. The main mosquito vector, Anopheles balabacensis, has adapted its habitat preference from closed canopy rainforest to more open logged forest and plantations. The eucalyptus plantations (Eucalyptus pellita) assessed in this study contained significantly higher abundance of many mosquito species compared with the other land uses, whereas the restored dipterocarp forest had a low abundance of all mosquitos, in particular, An. balabacensis. No P. knowlesi was detected by PCR assay in any of the vectors collected during the study; however, P. inui, P. fieldi and P. vivax were detected in An. balabacensis. These findings indicate that restoring degraded natural forests with native species to closed canopy conditions reduces abundance of this zoonotic malarial mosquito vector and therefore should be incorporated into future restoration research and potentially contribute to the control strategies against simian malaria.
