Workforce training needs to address social and emotional wellbeing in home-based Aboriginal and Torres Strait Islander aged care.

ObjectiveTo explore the training needs of the home care workforce in supporting the social and emotional wellbeing (SEWB) of Aboriginal and Torres Strait Islander peoples receiving aged care services through the Home Care Package (HCP) Program.MethodsA mixed-methods design including (1) a focus group and interview with coordinators of HCP Program services for Aboriginal and Torres Strait Islander peoples across metropolitan and rural South Australia in April and June 2022, and (2) a desktop review of training, professional development opportunities and resources for existing and pre-entry workforce addressing the SEWB of Aboriginal and Torres Strait Islander peoples in aged care across the Vocational Education Training and higher education sectors in South Australia, the Australian Indigenous HealthInfoNet, the Department of Health and Aged Care website and aged care email alerts between December 2021 and September 2022.ResultsFive themes representing workforce training needs were identified: cultural safety, trauma-informed care, case management, compliance with funding rules and preferred formats for training. The desktop review identified a paucity of formal training, professional development and resources within the context of addressing the SEWB of Aboriginal and Torres Strait Islander peoples in aged care.ConclusionsThese findings suggest that ongoing practice-based professional development learning opportunities are needed within organisations to enhance peer-learning and support. These need to be available together with dedicated formal training programs and practical resources on meeting Aboriginal and Torres Strait Islander peoples' SEWB in aged care.

Validation of the Kimberley Cognitive Assessment (KICA-Cog) for Torres Strait Islander Peoples.

OBJECTIVES: The aim of this study was to validate the Kimberley Indigenous Cognitive Assessment-Cognitive Component (KICA-Cog) adapted for dementia screening in Torres Strait Islander Peoples. METHODS: Data were obtained from a broader dementia prevalence study completed in the Torres Strait and Northern Peninsula Area between 2015 and 2018. Modifications were made to items from the original KICA-Cog to ensure they were culturally appropriate for the Torres Strait. All participants completed a KICA-Cog and had a comprehensive dementia assessment with a geriatrician experienced in cross-cultural assessment. RESULTS: A total of 255 Torres Strait residents aged 45 years and over completed a KICA-Cog and underwent geriatric assessment. The adapted KICA-Cog showed good validity for dementia diagnosis with a cut point of 33/34 associated with a sensitivity of 81% and specificity of 92% with an area under the ROC curve of 0.91. CONCLUSIONS: The KICA-Cog, when modified for the Torres Strait, is a valid cognitive screening tool for dementia. Caution is required when interpreting test scores, as the adapted KICA-Cog had slightly lower sensitivity (ability to detect people with dementia) than the original KICA-Cog. As with all short cognitive tests, individuals with a low KICA-Cog scores should undergo further medical investigations before a dementia diagnosis is considered.

Prevalence of functional limitations in older remote-living Aboriginal Australians.

INTRODUCTION: To better tailor prevention and care strategies, there is a need to identify modifiable factors associated with functional impairment in older Aboriginal people, and related service needs. OBJECTIVE: To investigate the prevalence and associated factors for functional impairment in older Aboriginal people, and related service needs. DESIGN: Cross-sectional survey of 289 Aboriginal people aged ≥45 years living in the remote Kimberley region of Western Australia. Factors associated with functional impairment were explored with logistic regression. FINDINGS: 41.2% (95% CI 35.6%-47.0%) of participants required assistance with at least one I/ADL, and 26.0% (95% CI 21.2%-31.3%) required assistance with two or more I/ADLs. A core activity limitation (required assistance with showering, dressing or cooking) was reported by 15.9% (95% CI 12.1%-20.6%). In multivariable logistic regression analyses, older age, diabetes, difficulty walking, head injury, higher depression score and worse cognition were associated with needing help with two or more I/ADLs, while older age, history of stroke, higher depression score and worse cognition were associated with the presence of a core activity limitation. The proportion of participants receiving support with I/ADLs ranged from 71.2% to 97.6%. Support was generally provided by family and friends rather than service providers. DISCUSSION: The key modifiable factors associated with functional impairment in older Aboriginal people living in remote regions are diabetes, depression and cognitive impairment. Services required are transport and socio-cultural activities, and ensuring support for family providing the majority of care. CONCLUSIONS: This study highlights the need for holistic prevention strategies and care for older Aboriginal people with functional limitations and their families.

Best practice models of aged-care implemented for First Nations people: a systematic review aligned with the Good Spirit Good Life quality of life principles.

BACKGROUND: Aged-care programs that are based in First Nations worldviews are believed to translate to improved quality of life for First Nations Elders. First Nations perspectives of health and well-being incorporates social and cultural determinants in addition to traditional Western biomedical approaches. This is exemplified by the Good Spirit Good Life (GSGL) framework, which comprises 12 strength-based factors determined by First Nations Elders as constituting culturally appropriate ageing. Our objective was to conduct a systematic review of existing aged care models of practice to determine the degree of alignment with the GSGL framework. Recommendations of the national Australian Royal Commission into Aged Care Quality and Safety informed this work. METHODS: We conducted a systematic search of academic and grey literature in the PubMed, Scopus, Ovid Embase, and Informit online databases. Inclusion criteria comprised English language, original research describing the implementation of First Nations culturally appropriate aged care models, published before August 2022. Research that was not focused on First Nations Elders' perspectives or quality of life was excluded. We subsequently identified, systematically assessed, and thematically analyzed 16 articles. We assessed the quality of included articles using the Aboriginal and Torres Strait Islander Quality Assessment Tool (ATSIQAT), and the Joanna Briggs Institute (JBI) critical appraisal tool for qualitative research. RESULTS: Most studies were of medium to high quality, while demonstrating strong alignment with the 12 GSGL factors. Nine of the included studies detailed whole service Models of care while 7 studies described a single program or service element. Thematic analysis of included studies yielded 9 enablers and barriers to implementing models of care. CONCLUSIONS: Best-practice First Nations aged care requires a decolonizing approach. Programs with strong adherence to the 12 GSGL factors are likely to improve Elders' quality of life.

Standardization of interstitial lung disease assessment by ultrasound: results from a Delphi process and web-reliability exercise by the OMERACT ultrasound working group.

OBJECTIVES: Over the last years ultrasound has shown to be an important tool for evaluating lung involvement, including interstitial lung disease (ILD) a potentially severe systemic involvement in many rheumatic and musculoskeletal diseases (RMD). Despite the potential sensitivity of the technique the actual use is hampered by the lack of consensual definitions of elementary lesions to be assessed and of the scanning protocol to apply. Within the Outcome Measures in Rheumatology (OMERACT) Ultrasound Working Group we aimed at developing consensus-based definitions for ultrasound detected ILD findings in RMDs and assessing their reliability in dynamic images. METHODS: Based on the results from a systematic literature review, several findings were identified for defining the presence of ILD by ultrasound (i.e., Am-lines, B-lines, pleural cysts and pleural line irregularity). Therefore, a Delphi survey was conducted among 23 experts in sonography to agree on which findings should be included and on their definitions. Subsequently, a web-reliability exercise was performed to test the reliability of the agreed definitions on video-clips, by using kappa statistics. RESULTS: After three rounds of Delphi an agreement >75 % was obtained to include and define B-lines and pleural line irregularity as elementary lesions to assess. The reliability in the web-based exercise, consisting of 80 video-clips (30 for pleural line irregularity, 50 for B-lines), showed moderate inter-reader reliability for both B-lines (kappa = 0.51) and pleural line irregularity (kappa = 0.58), while intra-reader reliability was good for both B-lines (kappa = 0.72) and pleural line irregularity (kappa = 0.75). CONCLUSION: Consensus-based ultrasound definitions for B-lines and pleural line irregularity were obtained, with moderate to good reliability to detect these lesions using video-clips. The next step will be testing the reliability in patients with ILD linked to RMDs and to propose a consensual and standardized protocol to scan such patients.

Predicting transfers to intensive care in children using CEWT and other early warning systems.

Background and Objective: The Children's Early Warning Tool (CEWT), developed in Australia, is widely used in many countries to monitor the risk of deterioration in hospitalized children. Our objective was to compare CEWT prediction performance against a version of the Bedside Pediatric Early Warning Score (Bedside PEWS), Between the Flags (BTF), and the pediatric Calculated Assessment of Risk and Triage (pCART). Methods: We conducted a retrospective observational study of all patient admissions to the Comer Children's Hospital at the University of Chicago between 2009-2019. We compared performance for predicting the primary outcome of a direct ward-to-intensive care unit (ICU) transfer within the next 12 h using the area under the receiver operating characteristic curve (AUC). Alert rates at various score thresholds were also compared. Results: Of 50,815 ward admissions, 1,874 (3.7%) experienced the primary outcome. Among patients in Cohort 1 (years 2009-2017, on which the machine learning-based pCART was trained), CEWT performed slightly worse than Bedside PEWS but better than BTF (CEWT AUC 0.74 vs. Bedside PEWS 0.76, P < 0.001; vs. BTF 0.66, P < 0.001), while pCART performed best for patients in Cohort 2 (years 2018-2019, pCART AUC 0.84 vs. CEWT AUC 0.79, P < 0.001; vs. BTF AUC 0.67, P < 0.001; vs. Bedside PEWS 0.80, P < 0.001). Sensitivity, specificity, and positive predictive values varied across all four tools at the examined thresholds for alerts. Conclusion: CEWT has good discrimination for predicting which patients will likely be transferred to the ICU, while pCART performed the best.

Medications and cognitive risk in Aboriginal primary care: a cross-sectional study.

BACKGROUND: Aboriginal and Torres Strait Islander people are ageing with high rates of comorbidity, yet little is known about suboptimal prescribing in this population. AIM: The prevalence of potentially suboptimal prescribing and associated risk factors were investigated among older patients attending primary care through Aboriginal Community Controlled Health Services (ACCHSs). METHODS: Medical records of 420 systematically selected patients aged ≥50 years attending urban, rural and remote health services were audited. Polypharmacy (≥ 5 prescribed medications), potentially inappropriate medications (PIMs) as per Beers Criteria and anticholinergic burden (ACB) were estimated and associated risk factors were explored with logistic regression. RESULTS: The prevalence of polypharmacy, PIMs and ACB score ≥3 was 43%, 18% and 12% respectively. In multivariable logistic regression analyses, polypharmacy was less likely in rural (odds ratio (OR) = 0.43, 95% confidence interval (CI) = 0.24-0.77) compared to urban patients, and more likely in those with heart disease (OR = 2.62, 95% CI = 1.62-4.25), atrial fibrillation (OR = 4.25, 95% CI = 1.08-16.81), hypertension (OR = 2.14, 95% CI = 1.34-3.44), diabetes (OR = 2.72, 95% CI = 1.69-4.39) or depression (OR = 1.91, 95% CI = 1.19-3.06). PIMs were more frequent in females (OR = 1.88, 95% CI = 1.03-3.42) and less frequent in rural (OR = 0.41, 95% CI = 0.19-0.85) and remote (OR = 0.58, 95% CI = 0.29-1.18) patients. Factors associated with PIMs were kidney disease (OR = 2.60, 95% CI = 1.37-4.92), urinary incontinence (OR = 3.00, 95% CI = 1.02-8.83), depression (OR = 2.67, 95% CI = 1.50-4.77), heavy alcohol use (OR = 2.83, 95% CI = 1.39-5.75) and subjective cognitive concerns (OR = 2.69, 95% CI = 1.31-5.52). High ACB was less common in rural (OR = 0.10, 95% CI = 0.03-0.34) and remote (OR = 0.51, 95% CI = 0.25-1.04) patients and more common in those with kidney disease (OR = 3.07, 95% CI = 1.50-6.30) or depression (OR = 3.32, 95% CI = 1.70-6.47). CONCLUSION: Associations between potentially suboptimal prescribing and depression or cognitive concerns highlight the importance of considering medication review and deprescribing for these patients.

Valuing indigenous quality of life: A review of preference-based quality of life instruments and elicitation techniques with global older indigenous populations.

Indigenous perspectives of quality of life (QoL) are different to that of non-Indigenous populations. Determining how to identify and value what is important to QoL for people from diverse cultural backgrounds is crucial for assessing effective outcomes for quality assessment and health economic evaluation to guide evidence-based decision making. This is particularly important for older Indigenous people who have complex care and support needs within health and aged-care systems. This scoping review aims to assess the existing literature in this field by firstly identifying preference based instruments that have been applied with older Indigenous peoples and secondly, exploring the extent to which existing preference based instruments applied with older Indigenous peoples encompass older Indigenous peoples QoL perspectives in their design and application. The inclusion criteria for the review were studies using preference based QoL instruments with an Indigenous population where the cohort was aged 50 years or over. This resulted in the critical analysis of 12 studies. The review identified that preference based QoL instruments have rarely been applied to date with older Indigenous populations with most instruments found to be designed for non-Indigenous adults. Typically, instruments have not incorporated Indigenous worldviews of QoL into either the content of the descriptive system or the elicitation techniques and corresponding value sets generated. To encapsulate Indigenous cultural perspectives accurately in economic evaluation, further research is required as to how QoL domains in preference based instruments for Indigenous peoples can be reflective of Indigenous perspectives. It is imperative that the QoL preferences of older Indigenous peoples are adequately captured within preference based QoL instruments applied with this population.

Challenges of accounting nitrous oxide emissions from agricultural crop residues.

Crop residues are important inputs of carbon (C) and nitrogen (N) to soils and thus directly and indirectly affect nitrous oxide (N2 O) emissions. As the current inventory methodology considers N inputs by crop residues as the sole determining factor for N2 O emissions, it fails to consider other underlying factors and processes. There is compelling evidence that emissions vary greatly between residues with different biochemical and physical characteristics, with the concentrations of mineralizable N and decomposable C in the residue biomass both enhancing the soil N2 O production potential. High concentrations of these components are associated with immature residues (e.g., cover crops, grass, legumes, and vegetables) as opposed to mature residues (e.g., straw). A more accurate estimation of the short-term (months) effects of the crop residues on N2 O could involve distinguishing mature and immature crop residues with distinctly different emission factors. The medium-term (years) and long-term (decades) effects relate to the effects of residue management on soil N fertility and soil physical and chemical properties, considering that these are affected by local climatic and soil conditions as well as land use and management. More targeted mitigation efforts for N2 O emissions, after addition of crop residues to the soil, are urgently needed and require an improved methodology for emission accounting. This work needs to be underpinned by research to (1) develop and validate N2 O emission factors for mature and immature crop residues, (2) assess emissions from belowground residues of terminated crops, (3) improve activity data on management of different residue types, in particular immature residues, and (4) evaluate long-term effects of residue addition on N2 O emissions.

Safeguarding against Dementia in Aboriginal and Torres Strait Islander Communities through the Optimisation of Primary Health Care: A Project Protocol.

This protocol describes the methodology and methods for a collaborative project with eight Aboriginal and Torres Strait Islander primary health care (PHC) organisations, across three Australian states and one territory, to increase clinical service performance and access to preventive health and health promotion services for preventing, identifying, treating, and managing dementia risk in Aboriginal and Torres Strait Islander communities. Aboriginal participatory action research (APAR) methodology will be the framework for this project, incorporating continuous quality improvement (CQI), informed by research yarning with stakeholder groups, comprising community members and PHC staff and service providers and data collected from the auditing of client health records and the mapping of existing clinical processes and health services at each partnering PHC organisation. The qualitative and quantitative data will be summarised and discussed with stakeholder groups. Priorities will be identified and broken down into tangible PHC organisation deliverable strategies and programs, which will be co-developed with stakeholder groups and implemented cyclically over 24 months using the Plan, Do, Study, Act model of change. Key project outcome measures include increased clinical service performance and availability of preventive health and health promotion services for safeguarding against dementia. Project implementation will be evaluated for quality and transparency from an Indigenous perspective using an appropriate appraisal tool. The project processes, impact, and sustainability will be evaluated using the RE-AIM framework. A dementia safeguarding framework and accompanying tool kit will be developed from this work to support Aboriginal and Torres Strait Islander PHC organisations to identify, implement, and evaluate dementia safeguarding practice and service improvements on a broader scale.

Forensic examination of a fragmentary funerary portrait in the collection of the Harvard art museums.

The Harvard Art Museums' collection includes six Egyptian funerary portraits of the Roman period. These portraits are all that remains of the funerary equipment of individuals whose bodies were carefully prepared for burial and the afterlife. One example, depicting a man, is particularly complicated, broken into multiple fragments which have been glued down onto a board. The in-depth study of the portrait used a combination of non-invasive techniques, including X-radiography, infrared-, ultraviolet- and visible-induced luminescence imaging, and X-ray fluorescence spectroscopy to identify and locate particular pigments, binders and other artist materials, without needing to take a sample. Targeted sampling, informed by the imaging process, was then undertaken for additional analysis through the use of cross-sections, scanning electron microscopy with energy dispersive X-ray spectrometry, Fourier transform infrared spectroscopy, Raman spectroscopy, radiocarbon dating, and lead isotope ratio analysis. This study identified a core group of three fragments in the center of the portrait that comprise much of the face and neck, tunic, and part of the hair. The remaining 15 fragments contain most of the background, parts of the hair, and the proper left eye and tunic, and are distinct from the central group of fragments. Analysis suggests these fragments were reused from other ancient funerary portraits, and whilst it was not possible to connect any of these added fragments to one another, a potential workshop connection between the central fragments and three added fragments can be suggested based on a study of the composition of the lead white pigment, and similarities in painting technique.

Identification of tumor-intrinsic drivers of immune exclusion in acral melanoma.

Background: Acral melanoma (AM) has distinct characteristics as compared to cutaneous melanoma and exhibits poor response to immune checkpoint inhibitors (ICI). Tumor-intrinsic mechanisms of immune exclusion have been identified in many cancers but less studied in AM. Methods: We characterized clinically annotated tumors from patients diagnosed with AM at our institution in correlation with ICI response using whole transcriptome RNAseq, whole exome sequencing, CD8 immunohistochemistry, and multispectral immunofluorescence imaging. A defined interferon-γ-associated T cell-inflamed gene signature was used to categorize tumors into non-T cell-inflamed and T cell-inflamed phenotypes. In combination with AM tumors from two published studies, we systematically assessed the immune landscape of AM and detected differential gene expression and pathway activation in a non-T cell-inflamed tumor microenvironment (TME). Two single-cell(sc) RNAseq AM cohorts and 11 bulk RNAseq cohorts of various tumor types were used for independent validation on pathways associated with lack of ICI response. In total, 892 specimens were included in this study. Results: 72.5% of AM tumors showed low expression of the T cell-inflamed gene signature, with 23.9% of total tumors categorized as the non-T cell-inflamed phenotype. Patients of low CD3 + CD8 + PD1 + intratumoral T cell density showed poor prognosis. We identified 11 oncogenic pathways significantly upregulated in non-T cell-inflamed relative to T cell-inflamed TME shared across all three acral cohorts (MYC, HGF, MITF, VEGF, EGFR, SP1, ERBB2, TFEB, SREBF1, SOX2, and CCND1). scRNAseq analysis revealed that tumor cell-expressing pathway scores were significantly higher in low vs high T cell-infiltrated AM tumors. We further demonstrated that the 11 pathways were enriched in ICI non-responders compared to responders across cancers, including acral melanoma, cutaneous melanoma, triple-negative breast cancer, and non-small cell lung cancer. Pathway activation was associated with low expression of interferon stimulated genes, suggesting suppression of antigen presentation. Across the 11 pathways, fatty acid synthase and CXCL8 were unifying downstream target molecules suggesting potential nodes for therapeutic intervention. Conclusions: A unique set of pathways is associated with immune exclusion and ICI resistance in AM. These data may inform immunotherapy combinations for immediate clinical translation.

Probing ion-binding at a protein interface: Modulation of protein properties by ionic liquids.

Ions are important to modulate protein properties, including solubility and stability, through specific ion effects. Ionic liquids (ILs) are designer salts with versatile ion combinations with great potential to control protein properties. Although protein-ion binding of common metals is well-known, the IL effect on proteins is not well understood. Here, we employ the model protein lysozyme in dilute and concentrated IL solutions to determine the specific ion binding effect on protein phase behaviour, activity, size and conformational change, aggregation and intermolecular interactions. A combination of spectroscopic techniques, activity assays, small-angle X-ray scattering, and crystallography highlights that ILs, particularly their anions, bind to specific sites in the protein hydration layer via polar contacts on charged, polar and aromatic residues. The specific ion binding can induce more flexible loop regions in lysozyme, while the ion binding in the bulk phase can be more dynamic in solution. Overall, the protein behaviour in ILs depends on the net effect of nonspecific interactions and specific ion binding. Compared to formate, the nitrate anion induced high protein solubility, low activity, elongated shape and aggregation, which is largely owing to its higher propensity for ion binding. These findings provide new insights into protein-IL binding interactions and using ILs to modulate protein properties.

Does the halo count on temporal and axillary ultrasound predict time to relapse in giant cell arteritis?

OBJECTIVES: To determine whether the halo count (HC) on temporal and axillary artery US (TAUS) predicts time to relapse in giant cell arteritis (GCA). METHODS: We conducted a single-centre retrospective study of GCA patients. HC, the number of vessels with non-compressible halo on the TAUS at diagnosis, was determined by retrospective review of the US report and images. Relapse was defined as increase in GCA disease activity requiring treatment escalation. Cox proportional hazard regression was used to identify predictors of time to relapse. RESULTS: A total of 72 patients with confirmed GCA were followed up for a median of 20.9 months. Thirty-seven of 72 (51.4%) relapsed during follow-up, at a median prednisolone dose of 9 mg (range 0-40 mg). Large-vessel (axillary artery) involvement did not predict relapse. On univariable analysis, a higher HC was associated with shorter time to relapse (per-halo hazard ratio 1.15, 95% CI 1.02, 1.30; P = 0.028). However, statistical significance was lost when the 10 GCA patients with an HC of zero were excluded from analysis. CONCLUSION: In this real-world setting, relapse occurred at a wide range of glucocorticoid doses and was not predicted by axillary artery involvement. GCA patients with a higher HC at diagnosis were significantly more likely to relapse, but significance was lost on excluding those with HC of zero. HC is feasible in routine care and may be worth incorporating into future prognostic scores. Further research is required to determine whether confirmed GCA patients with negative TAUS represent a qualitatively different subphenotype within the GCA disease spectrum.

CX-ASAP: a high-throughput tool for the serial refinement and analysis of crystallographic data collected under varying conditions.

CX-ASAP is a new open-source software project designed to greatly reduce the time required to analyse crystallographic data collected under varying conditions. Scripted in Python3, CX-ASAP can automatically refine, finalize and analyse data collections with wide-ranging temperatures, pressures etc. This is achieved using a reference structure, allowing for quick identification of problems, phase changes and even model comparison. The modular design means that new features and customized scripts can be easily added, tailoring the capabilities to the specific needs of the user. It is envisioned that CX-ASAP will help to close the growing gap between fast collection times and slow data finalization.

SDU - software for high-throughput automated data collection at the Swiss Light Source.

Recent advances in automation have fostered the development of unattended data collection services at a handful of synchrotron facilities worldwide. At the Swiss Light Source, the installation of new high-throughput sample changers at all three macromolecular crystallography beamlines and the commissioning of the Fast Fragment and Compound Screening pipeline created a unique opportunity to automate data acquisition. Here, the DA+ microservice software stack upgrades, implementation of an automatic loop-centering service and deployment of the Smart Digital User (SDU) software for unattended data collection are reported. The SDU software is the decision-making software responsible for communications between services, sample and device safety, sample centering, sample alignment with grid based X-ray diffraction and, finally, data collection.

Co-design of dementia prevention program for Aboriginal Australians (DAMPAA).

INTRODUCTION: Dementia is highly prevalent in older Aboriginal Australians, with several modifiable risk factors. Currently, there is limited evidence on how to prevent cognitive decline in Aboriginal Australians. METHODS: Based on our Theory of Change (ToC) framework, we co-developed the Dementia risk management and prevention program for Aboriginal Australians (DAMPAA) aged over 45 years in partnership with Aboriginal community-controlled organizations (ACCOs) and Elders. Qualitative data were collected through ACCO staff workshops, Elders yarning, and governance groups to inform the protocol. Additionally, we conducted a small pilot study. RESULTS: Expected DAMPAA ToC outcomes are: (1) improved daily function, (2) better cardiovascular risk management, (3) falls reduction, (4) improved quality of life, and (5) reduced cognitive decline. Attendance enablers are social interaction, environment, exercise type/level, and logistics. DISCUSSION: Findings suggest that ToC is an effective collaborative approach for co-designing Aboriginal health programs.

Illustrating Resource Needs through Data Visualization: Creation of Life-Space Maps for Rural Veterans with Dementia and their Caregivers.

Rural-dwelling individuals with dementia and their caregivers face unique challenges compared to urban-dwelling peers. Barriers to accessing services and supports are common, and individual resources and informal networks available to support rural families can be difficult to track for providers and healthcare systems outside of the local community. This study uses qualitative data from rural-dwelling dyads, individuals with dementia (n = 12) and informal caregivers (n = 18), to demonstrate how rural patients' daily life needs can be summarized through life-space map visualizations. Thirty semi-structured qualitative interviews were analyzed using a two-step process. First, rapid qualitative analysis was completed to generate daily-life needs of the participants' home and community context. Next, life-space maps were developed to synthesize and visualize dyads' met and unmet needs. Results suggest life-space mapping may offer a pathway for improved needs-based information integration for busy care providers and time-sensitive quality improvement efforts by learning healthcare systems.

China's enhanced urban wastewater treatment increases greenhouse gas emissions and regional inequality.

Sustainable water pollution control requires understanding of historical trajectories and spatial characteristics of greenhouse gas (GHG) emissions from wastewater treatment plants (WWTPs), which remains inadequately studied. Here, we establish plant-level monthly operational emissions inventories of China's WWTPs in 2009-2019. We show that urban wastewater treatment has been enhanced with 80% more chemical oxygen demand being removed annually. However, this progress is associated with 180% more GHG emissions at the national level, up to 58.3 Mt CO2 eq in 2019. We found significant seasonality in GHG emissions. Increasing sludge yield and electricity intensity became primary drivers after 2015 because of stricter standards, causing GHG emissions increase 12.9 and 8.3% until 2019. GHG emissions from urban wastewater treatment show high spatial difference at province, city and plant levels, with different sludge disposal and energy mix approaches combined with different influent and effluent conditions in WWTPs across China. Stricter effluent standard resulted in similar GHG emissions growth pattern in cities. We argue WWTPs focus on resource recovery in developed areas and higher operational efficiency in developing areas.

Culturally Appropriate Assessment of Depression and Anxiety in Older Torres Strait Islanders: Limitations and Recommendations.

OBJECTIVES: The aim of the study was to assess the prevalence of anxiety and depression in older Aboriginal and Torres Strait Islander adults. METHODS: A modified version of the PHQ-9 (KICA-dep) and the Geriatric Anxiety Inventory (GAI) were administered as part of a wider dementia prevalence study conducted in the Torres Strait. Results were compared to diagnoses obtained on Geriatric review to evaluate their applicability in the region. RESULTS: A total of 236 participants completed the KICA-dep and 184 completed the GAI short form. Of these, 10.6% were identified with depression and 15.8% with anxiety. Some participants found questions about suicide ideation and self-harm offensive and others had difficulty understanding concepts on the GAI. The KICA-dep performed poorly in comparison to diagnosis on geriatric clinical review, so results are unlikely to reflect the true prevalence of depression in the region. CONCLUSIONS: Further research is required to explore the underlying dimensions of depression and anxiety and terminology used to express mood symptoms in the Torres Strait. CLINICAL IMPLICATIONS: • Current mental health screening tools are not applicable for the Torres Strait• More work is required to determine how symptoms of depression and anxiety are expressed within Torres Strait communities.
