Impact of pregnancy vaccine uptake and socio-demographic determinants on subsequent childhood Measles, Mumps and Rubella vaccine uptake: A UK birth cohort study

BACKGROUND

We examined the association between socio-demographic determinants and uptake of childhood Measles, Mumps & Rubella (MMR) vaccines and the association between pregnant women's pertussis vaccine uptake and their children's MMR vaccine uptake.

METHODS

We used nationally-representative linked mother-baby electronic records from the United Kingdom's Clinical-Practice-Research-Datalink. We created a birth cohort of children born between 01.01.2000 and 12.12.2020. We estimated the proportion vaccinated with first MMR vaccine by age 2 years and first and second MMR vaccines by age 5 years. We used survival-analysis and Cox proportional hazard models to examine the association between deprivation, ethnicity and maternal age and pertussis vaccination in pregnancy and children's MMR uptake.

RESULTS

Overall, 89.4 % (710,797/795,497) of children had first MMR by age 2 years and 92.6 % (736,495/795,497) by age 5 years. Among children still in the cohort when second MMR was due, 85.9 % (478,480/557,050) had two MMRs by age 5 years. Children from the most-deprived areas, children of Black ethnicity and children of mothers aged < 20 years had increased risk of being unvaccinated compared with children from the least-deprived areas, White children and children of mothers aged 31-40 years: first MMR by 5 years, adjusted Hazard Ratios (HR):0.86 (CI:0.85-0.87), HR:0.87 (CI:0.85-0.88) & HR:0.89 (CI:0.88-0.90) respectively. Deprivation was the determinant associated with the greatest risk of missed second MMR: adjusted HR:0.82 (CI:0.81-0.83). Children of mothers vaccinated in pregnancy were more likely than children of unvaccinated mothers to have MMR vaccines after adjusting for ethnicity, deprivation, and maternal age (First and Second MMRs adjusted HRs:1.43 (CI:1.41-1.45), 1.49 (CI:1.45-1.53).

CONCLUSION

Children from most-deprived areas are less likely to have MMR vaccines compared with children from least-deprived areas. Mothers who take up pregnancy vaccines are more likely to have their children vaccinated with MMR. Healthcare services should promote and facilitate access to both maternal and childhood vaccines during pregnancy.

Australian women's experiences of post-partum rectus diastasis: A qualitative study

BACKGROUND

Post-partum rectus diastasis, or the separation of the abdominal muscles after pregnancy, occurs in conjunction with physical symptoms and impaired quality of life. In Australia, health funding for surgery to treat diastasis was ceased in 2016, but reinstated in mid-2022, providing a unique context from which women's experiences of this condition can be analysed.

OBJECTIVES

The objective is to examine the experiences of Australian women with post-partum rectus diastasis.

DESIGN

This is an interview-style study with qualitative content analysis.

METHODS

Women diagnosed with rectus diastasis were recruited to complete a baseline questionnaire (n = 45). Twenty-three responded to invitation for one-on-one interview via Zoom® between November 2021 and May 2022. Interviews were recorded, transcribed, and analysed using qualitative content analysis to identify key themes.

RESULTS

Eighteen women had undergone caesarean section and eight had twins. Thirteen had private health insurance. Women were most often diagnosed by a physiotherapist (n = 10). Key themes identified included changed physical appearance and function; issues with self-esteem and intimacy; barriers to treatment; lack of recognition as a medical condition; and overall frustration. The impact of rectus diastasis extended beyond physical and psychological symptoms to affect women's social functioning, child rearing, and return to work. There was a complex interaction between healthcare providers' knowledge of rectus the removal of funding for surgical treatment, and limitations of conservative therapy, with women's lived experiences and symptoms. The lack of an established medical definition also influenced the experiences of these women and their engagement with treatment.

CONCLUSION

This study contextualizes women's experience of post-partum rectus diastasis with respect to the unique landscape of Australia's healthcare economy and provides evidence of women's absorption of health policy surrounding this condition. Our qualitative analysis provides critical knowledge for future quantitative studies, the results of which in combination could advance the definition of rectus diastasis and inform healthcare policy surrounding treatment.

Developing a Women's Thought Collective methodology for health research: The roles and responsibilities of researchers in the reflexive co-production of knowledge

BACKGROUND

Co-produced research holds enormous value within the health sciences. Yet, there can be a heavy focus on what research participants think, do and know; while the researcher's responsibility to explore and re/work their own knowledge or praxis tends to escape from view. This is reflected in the limited use of co-production to explore broad structural distributions of health and risk(s). We argue this missed opportunity has the potential to unfold as what Berlant calls a 'cruel optimism', where something desirable becomes an obstacle to flourishing and/or produces harm. We explore challenges to involving lay populations meaningfully in health research amidst a neoliberal cultural landscape that tends to responsibilise people with problems they cannot solve.

METHODS AND FINDINGS

Drawing together principles from hermeneutic and feminist philosophy, we develop a novel methodology for co-producing research about determinants of health and health risk (using a case study of alcohol consumption as an example) that centres on what researchers do, know and think during research: Women's Thought Collectives.

DISCUSSION

Keeping the constructed nature of social systems-because they shape ideas of value, expertise and knowledge-in view during co-produced research illuminates the potential for cruel optimisms within it. Such reflexive awareness carves out starting points for researchers to engage with how social hierarchies might (tacitly) operate during the co-production of knowledge. Our work has broad utility for diverse population groups and provides important considerations around the roles and responsibilities for reflexive co-production of knowledge at all levels of health systems.

PATIENT OR PUBLIC CONTRIBUTION

The development of these ideas was sparked by working with lay participants during the Women's Thought Collectives for Kristen Foley's doctoral research 2021-2023, but undertaken without their direct involvement-in accordance with the responsibilities of researchers in the reflexive co-production of knowledge. Forthcoming publications will address the outcomes and processes of this work.

Logic modelling as hermeneutic praxis: Bringing knowledge systems into view during comprehensive primary health care planning for homelessness in Australia

Logic modelling is used widely in health promotion planning for complex health and social problems. It is often undertaken collaboratively with stakeholders across sectors that hold and enact different institutional approaches. We use hermeneutic philosophy to explore how knowledge is 'lived' by - and unfolds differently for - cross-sectoral stakeholders during comprehensive primary healthcare service planning. An Organisational Action Research partnership was established with a non-government organisation designing comprehensive primary health care for individuals experiencing homelessness in Adelaide, Australia. Grey literature, stakeholder input, academic feedback, a targeted literature review and evidence synthesis were integrated in iterative cycles to inform and refine the logic model. Diverse knowledge systems are active when cross-sectoral stakeholders collaborate on logic models for comprehensive primary health care planning. Considering logic modelling as a hermeneutic praxis helps to foreground and explore these differences. In our case, divergent ideas emerged in how health/wellbeing and trust were conceptualised; language had different meanings across sectors; and the outcomes and data sought were nuanced for various collaborators. We explicate these methodological insights and also contribute our evidence-informed, collaboratively-derived model for design of a comprehensive primary health care service with populations experiencing homelessness. We outline the value of considering cross-sectoral logic modelling as hermeneutic praxis. Engaging with points of difference in cross-sectoral knowledge systems can strengthen logic modelling processes, partnerships and potential outcomes for complex and comprehensive primary health care services.

"There's been a huge change": Educator experiences of a whole-school SLP-led project to address developmental language disorder in three Australian secondary schools

PURPOSE

Developmental Language Disorder (DLD) remains prevalent for secondary school students and continues to compromise educational, social and vocational outcomes within and beyond school. Community-based approaches to service provision are needed to use speech-language pathology resources effectively in realising benefits for this student population. Our article focusses on educator experiences of a whole-school project facilitated by a speech-language pathologist (SLP) to address DLD in secondary school settings.

METHOD

Twenty-one educators were interviewed across three schools to understand their perceptions and experiences of the project and their view(s) of what assisted or compromised early implementation. Data were analysed inductively to develop key themes.

RESULT

Educators reported gaining increased knowledge and awareness of DLD, which supported a reframing of their perceptions of student behaviour and learning issues. They identified the project provided them with ready skills and tools to change their practice, realised learning benefits for all the students they taught, aligned with broader school initiatives, and overcame potential challenges to supporting project implementation.

CONCLUSION

Overall, the educators found the project and implementation of strategies doable, acceptable, important, and sustainable. We explore the features of project design that appeared to contribute to educators' positive experience of the project. This knowledge will be helpful for SLPs using innovative service approaches in classroom settings.

Through the wine glass: How biographical midlife transitions and women's affective interpretations interact with alcohol consumption

BACKGROUND

Women during midlife are consuming larger quantities of alcohol than any other age group of women and any other generation of midlife women previously. This is concerning given alcohol related-health risks coalesce with age-related health risks for women, in particular, breast cancer.

METHODS

In-depth interviews with 50 Australian midlife women (aged 45-64) from different social classes explored women's personal accounts of midlife transitions and their descriptions of the role of alcohol in navigating these life experiences; both daily occurrences as well as significant moments in the life course.

RESULTS

Our findings point to the complex, confusing and co-existing biographical transitions women experience during midlife (generational, embodied/physiological and material changes) that sharpen a role for alcohol in women's lives and are nuanced by social class (volumes of social, economic and cultural capital). We pay close attention to women's affective interpretations of these transitions and ways alcohol is used to feel robust in navigating daily life or easing their prospective futures. Critically, for women living with limited access to capital, and who could not 'measure up' to social ideals by comparison with the achievements and trajectories of other midlife women, alcohol reconciled their disappointment. Our exploration shows how the social class conditions that shape how women make sense of their transitions through midlife might be differently shaped to enable different options forreducing drinking.

CONCLUSIONS

Policy must address the social and emotional concerns women experience through midlife transitions that give alcohol a worthwhile place in their lives. A first step might be responding to the absence of community and leisure spaces for midlife women especially those that do not integrate alcohol, with benefits including addressing loneliness, isolation and feeling invisible, and enabling positive constructions of midlife identities. Structural barriers to participation and feelings of worth must be removed for women who lack social, cultural and economic resources.

Characterizing variations in ambient PM2.5 concentrations at the U.S. Embassy in Dhaka, Bangladesh using observations and the CMAQ modeling system

We analyze hourly PM2.5 (particles with an aerodynamic diameter of ≤ 2.5 μm) concentrations measured at the U.S. Embassy in Dhaka over the 2016 - 2021 time period and find that concentrations are seasonally dependent with the highest occurring in winter and the lowest in monsoon seasons. Mean winter PM2.5 concentrations reached ~165-175 μg/m3 while monsoon concentrations remained ~30-35 μg/m3. Annual mean PM2.5 concentration reached ~5-6 times greater than the Bangladesh annual PM2.5 standard of 15 μg/m3. The number of days exceeding the daily PM2.5 standard of 65 μg/m3 in a year approached nearly 50%. Daily-mean PM2.5 concentrations remained elevated (>65 μg/m3) for more than 80 consecutive days. Night-time concentrations were greater than daytime concentrations. The comparison of results obtained from the Community Multiscale Air Quality (CMAQ) model simulations over the Northern Hemisphere using 108-km horizontal grids with observed data suggests that the model can reproduce the seasonal variation of observed data but underpredicts observed PM2.5 in winter months with a normalized mean bias of 13-32%. In the model, organic aerosol is the largest component of PM2.5, of which secondary organic aerosol plays a dominant role. Transboundary pollution has a large impact on the PM2.5 concentration in Dhaka, with an annual mean contribution of ~40 μg/m3.

Allied health workforce development for participant-led services: structures for student placements in the National Disability Insurance Scheme

BACKGROUND

Health, disability, and community services are increasingly transitioning from government-led to participant-led funding models, which intend to increase choice and control for service users. Allied health practitioners, who provide many frontline services within the resultant marketised environment, must adjust their knowledge and skills to meet participants' expectations. However, future workforce strategies to address allied health student capabilities to provide these services have received limited attention. This study explored shifting understandings and practices related to allied health student placements during the implementation of a participant-led funding model within the Australian disability sector: the National Disability Insurance Scheme (NDIS).

METHODS

Data for this study came from a two-year disability workforce project exploring allied health placements. Service providers, participants, university representatives, disability advocates and students participated in 48 interviews and two focus groups to provide perspectives on allied health workforce and student placements. The findings result from secondary deductive analysis undertaken following project completion that used Gidden's (1984) Structuration Theory as a conceptual lens to identify structures and actions related to the marketised service environment that influenced how allied health student placements were undertaken.

RESULTS

The findings were organised using two Structuration concepts: knowledgeability, and duality of structure. These described how service providers, supervisors and students understood, legitimised and prioritised placement activities, and how these structures influenced and were influenced by the actions of stakeholders across NDIS settings, contexts and time. Initially, existing placement structures were not compatible with new structures emerging in the disrupted NDIS service environment. However, over time, and responding to new knowledgeability of service providers, supervisors and students, placement structures were identified, monitored and adjusted to reflect perspectives of all stakeholders.

CONCLUSIONS

Participant-led funding invoked structural changes in disability service provision that transformed how stakeholders understood placements and the role of students in service provision. Whilst there were new opportunities for placement, tensions were identified in how learning activities can be enacted within a marketised system in which resources are aligned to participant needs, and structures for workforce development and learning activities are less visible. Further conceptualisation of how student learning and workforce development activities can fit with contemporary funding models is necessary to meet participant, service provider and student needs.

Prioritising Children and Young People with Disability in Research About Domestic and Family Violence: Methodological, Ethical and Pragmatic Reflections

Purpose

The perspectives of children and young people with disability who experience domestic and family violence are under-researched, impeding the development of approaches that meet their needs. Knowledge gaps stem from the layered discursive positioning of disability, childhood/youth, or domestic and family violence in addition to the methodological, ethical and pragmatic complexity of research needed to understand their priorities and be attuned to their lived experience. This article explores methodological, ethical and practical challenges to centring their voices in research about domestic and family violence.

Method

A conceptual framework of feminist disability theory and intersectionality informed our co-designed research, across three phases: (1) quantitative large-scale data linkage and case file analysis; (2) qualitative research with children and young people, their families and service providers and (3) stakeholder engagement workshops.

Results

We reflect on how our research was able to prioritise the contextual agency of children and young people with disability, ways it could not, and other constraints.

Conclusion

Children and young people with disability experiencing domestic and family violence hold an expert and unique vantage point on what happens to them. Amplifying their priorities for directing policy and organisational change requires more of researchers in terms of methods, but also more flexibility in how projects are funded to enable creativity and innovation. We call for collective attention to frameworks for supported decision-making and child ethics to progress inclusive research which recognises the importance of participation for children and young people with disability.

Sober Curiosity: A Qualitative Study Exploring Women's Preparedness to Reduce Alcohol by Social Class

BACKGROUND

Urgent action is required to identify socially acceptable alcohol reduction options for heavy-drinking midlife Australian women. This study represents innovation in public health research to explore how current trends in popular wellness culture toward 'sober curiosity' (i.e., an interest in what reducing alcohol consumption would or could be like) and normalising non-drinking could increase women's preparedness to reduce alcohol consumption.

METHODS

Qualitative interviews were undertaken with 27 midlife Australian women (aged 45-64) living in Adelaide, Melbourne and Sydney in different social class groups (working, middle and affluent-class) to explore their perceptions of sober curiosity.

RESULTS

Women were unequally distributed across social-classes and accordingly the social-class analysis considered proportionally the volume of data at particular codes. Regardless, social-class patterns in women's preparedness to reduce alcohol consumption were generated through data analysis. Affluent women's preparedness to reduce alcohol consumption stemmed from a desire for self-regulation and to retain control; middle-class women's preparedness to reduce alcohol was part of performing civility and respectability and working-class women's preparedness to reduce alcohol was highly challenging. Options are provided for alcohol reduction targeting the social contexts of consumption (the things that lead midlife women to feel prepared to reduce drinking) according to levels of disadvantage.

CONCLUSION

Our findings reinstate the importance of recognising social class in public health disease prevention; validating that socially determined factors which shape daily living also shape health outcomes and this results in inequities for women in the lowest class positions to reduce alcohol and related risks.

Examining social class as it relates to heuristics women use to determine the trustworthiness of information regarding the link between alcohol and breast cancer risk

Background

High rates of alcohol consumption by midlife women, despite the documented risks associated with breast cancer, varies according to social class. However, we know little about how to develop equitable messaging regarding breast cancer prevention that takes into consideration class differences in the receipt and use of such information.

Objective

To explore the heuristics used by women with different (inequitable) life chances to determine the trustworthiness of information regarding alcohol as a modifiable risk factor for breast cancer risk.

Methods and materials

Interviews were conducted with 50 midlife (aged 45–64) women living in South Australia, diversified by self-reported alcohol consumption and social class. Women were asked to describe where they sought health information, how they accessed information specific to breast cancer risk as it relates to alcohol, and how they determined whether (or not) such information was trustworthy. De-identified transcripts were analysed following a three-step progressive method with the aim of identifying how women of varying life chances determine the trustworthiness of alcohol and breast cancer risk information. Three heuristics were used by women: (1) consideration of whose interests are being served; (2) engagement with ‘common sense’; and (3) evaluating the credibility of the message and messenger. Embedded within each heuristic are notable class-based distinctions.

Conclusions

More equitable provision of cancer prevention messaging might consider how social class shapes the reception and acceptance of risk information. Class should be considered in the development and tailoring of messages as the trustworthiness of organizations behind public health messaging cannot be assumed.

'I have a healthy relationship with alcohol': Australian midlife women, alcohol consumption and social class

Alcohol consumption by Australian women during midlife has been increasing. Health promotion efforts to reduce alcohol consumption in order to reduce alcohol-related disease risk compete with the social contexts and value of alcohol in women's lives. This paper draws on 50 qualitative interviews with midlife women (45-64 years of age) from different social classes living in South Australia in order to gain an understanding of how and why women might justify their relationships with alcohol. Social class shaped and characterized the different types of relationships with alcohol available to women, structuring their logic for consuming alcohol and their ability to consider reducing (or 'breaking up with') alcohol. We identified more agentic relationships with alcohol in the narratives of affluent women. We identified a tendency for less control over alcohol-related decisions in the narratives of women with less privileged life chances, suggesting greater challenges in changing drinking patterns. If classed differences are not attended to in health promotion efforts, this might mitigate the effectiveness of alcohol risk messaging to women.

Place of alcohol in the 'wellness toolkits' of midlife women in different social classes: A qualitative study in South Australia

In this article, we explore how women in different social classes had differential access to resources and services to enhance their 'wellness'-resulting in classed roles in alcohol consumption. We analyse data from a qualitative study on alcohol by midlife women in South Australia and employ the analogy of a 'toolkit' in order to understand the structural patterning of 'wellness tools'. Bourdieu's relational model of class guides our exploration of women's inequitable opportunities for wellness. Higher social class women had 'choices' facilitated by bulging wellness toolkits, such as yoga, exercise and healthy eating regimens-alcohol consumption was not essential to promoting 'wellness' and did not have an important place in their toolkits. Middle-class women had less well-stocked toolkits and consumed alcohol in a 'compensation approach' with other wellness tools. Alcohol consumption received positive recognition and was a legitimised form of enjoyment, fun and socialising, which needed counterbalancing with healthy activities. Working-class women had sparse toolkits-other than alcohol-which was a tool for dealing with life's difficulties. Their focus was less on 'promoting wellness' and more on 'managing challenging circumstances'. Our social class-based analysis is nestled within the sociology of consumption and sociological critiques of the wellness industry.

A core outcome set for school-based physical activity interventions: an international consensus

Background

Studies of school-based physical activity interventions vary in the outcomes they measure. This prevents comparisons of results to establish impacts. We aimed to develop a core outcome set agreed by key stakeholders for future studies of school-based physical activity interventions.

Methods

We used a modified-Delphi consensus method. First, we conducted a systematic review to identify outcomes measured in relevant studies and listed these in a Delphi survey. Next, we recruited key stakeholders to complete 2 survey rounds: Round 1 was to rate each outcome from ‘not important' to ‘critical', and Round 2 was to re-rate the outcomes based on feedback from Round 1. Outcomes rated ‘critical' by 70% of stakeholders (i.e., reaching consensus) were highlighted. Then, using the full list of outcomes, we conducted a children's workshop to include their views. Finally, we held a stakeholder meeting to discuss results and agree consensus.

Results

We identified 50 outcomes from the systematic review. Sixty-five stakeholders (16 educators, 13 health professionals, 12 parents, 24 researchers) representing 9 countries completed both survey rounds; 13/50 outcomes reached consensus. Children (n = 16) identified 8 outcomes of importance; 3 were consistent with the survey results. Stakeholders attending the meeting (n = 13) reached consensus on 14 outcomes to be included in the core outcome set: fitness, physical activity intensity, energy, sleep, diet, happiness, stress, depression, anxiety, wellbeing, self-esteem, enjoyment, concentration, and focus. These core outcomes were reviewed and agreed by all 65 stakeholders.

Conclusions

Our core outcome set agreed by international stakeholders includes physical and mental health, and cognitive function. We recommend its use in future studies of school-based physical activity interventions. Findings from future studies can be compared and combined which will be relevant to public health policy makers and educators.

Key messages

School-based physical activity interventions should measure physical and mental health, and cognitive function. Wide use of this core outcome set will enable findings to be compared and combined.

Exploring access to, use of and benefits from population-oriented digital health services in Australia

The provision of population-oriented, on-demand digital health services in many countries exemplifies the perceived utility of digital health services in supporting population health. Yet, limited knowledge exists regarding the equity of these services. Using mixed-method research, we recruited users of a health website and general practice patients to surveys (n = 441) and telephone interviews (n = 40). We contribute specific evidence investigating barriers to access, use and benefit from digital health services within an equity framework that incorporates social determinant factors, eHealth Literacy and trust. Our research highlights the foundational role of trust in predicting use, showcases which groups are unlikely to benefit from population-oriented digital health services, and proposes strategies to enhance the equity of these services. The theoretical framework we developed serves as a roadmap for future health promotion research and action by outlining the complex and interrelated pathways that can promote and threaten digital health equity.

Barriers to digital health services among people living in areas of socioeconomic disadvantage: Research from hospital diabetes and antenatal clinics

ISSUE ADDRESSED

We sought to examine barriers to access to, use of, and benefits from digital health services in an area of socioeconomic disadvantage of Adelaide, Australia.

METHODS

We conducted waiting room surveys in two hospital diabetes clinics and one hospital antenatal clinic in South Australia, and follow-up telephone interviews with 20 patients. We examined the extent of access to, use of and benefits from digital health services, and what barriers people encountered. We undertook mixed methods, with quantitative descriptive analysis and qualitative analysis.

RESULTS

Thirty-seven diabetes clinic patients (54% response rate) and 99 antenatal clinic patients (33% response rate) participated. Sixty-two percent of the patients with diabetes and 27% of antenatal clinic patients had never used digital health services. Seventeen percent of patients with diabetes and 30% of antenatal clinic patients were hesitant users, and 22% of patients with diabetes and 44% of antenatal clinic patients were confident users. Barriers included struggling to afford the technology or to stay connected and a lack of trust in online health information. Potential benefits included feeling more empowered and complementing face-to-face care.

CONCLUSIONS

There are socioeconomic barriers to access, use of, and ability to benefit from digital health strategies that mean not everyone will be able to benefit from digital health services. SO WHAT?: As COVID-19 accelerates the shift towards digital health services, people experiencing socioeconomic disadvantage may be excluded. If barriers to access and use are not addressed, they will exacerbate already increasing health inequities.

Artificial intelligence in radiation oncology: A review of its current status and potential application for the radiotherapy workforce

OBJECTIVE

Radiation oncology is a continually evolving speciality. With the development of new imaging modalities and advanced imaging processing techniques, there is an increasing amount of data available to practitioners. In this narrative review, Artificial Intelligence (AI) is used as a reference to machine learning, and its potential, along with current problems in the field of radiation oncology, are considered from a technical position.

KEY FINDINGS

AI has the potential to harness the availability of data for improving patient outcomes, reducing toxicity, and easing clinical burdens. However, problems including the requirement of complexity of data, undefined core outcomes and limited generalisability are apparent.

CONCLUSION

This original review highlights considerations for the radiotherapy workforce, particularly therapeutic radiographers, as there will be an increasing requirement for their familiarity with AI due to their unique position as the interface between imaging technology and patients.

IMPLICATIONS FOR PRACTICE

Collaboration between AI experts and the radiotherapy workforce are required to overcome current issues before clinical adoption. The development of educational resources and standardised reporting of AI studies may help facilitate this.

Co-designing a methodology for workforce development during the personalisation of allied health service funding for people with disability in Australia

Background

Internationally, health and social services are undergoing creative and extensive redesign to meet population demands with rationed budgets. This has critical implications for the health workforces that serve such populations. Within the workforce literature, few approaches are described that enable workforce development for health professions in the service contexts that emerge from large scale service redesign in times of industry shift. We contribute an innovative and robust methodology for workforce development that was co-designed by stakeholders in allied health during the personalisation of disability funding in Australia (the introduction of the National Disability Insurance Scheme).

Methods

In the context of a broad action research project, we used program logic modelling to identify and enact opportunities for sustainable allied health education and workforce integration amidst the changed service provision context. We engaged with 49 industry stakeholders across 92 research engagements that included interviews (n = 43), a workshop explicitly for model development (n = 8) and a Project Advisory Group (n = 15). Data from these activities were inductively coded, analysed, and triangulated against each other. During the program logic modelling workshop, we worked with involved stakeholders to develop a conceptual model which could be used to guide trial and evaluation of allied health education which was fit-for-purpose to emerging workforce requirements.

Results

Stakeholder interviews showed that drivers of workforce design during industry shift were that (1) service provision was happening in turbulent times; (2) new concerns around skills and professional engagement were unfolding for AHP in the NDIS; and (3) impacts to AHP education were being experienced. The conceptual model we co-designed directly accounted for these contextual features by highlighting five underpinning principles that should inform methodologies for workforce development and AHP education in the transforming landscape: being (1) pedagogically sound; (2) person- or family-centred; (3) NDIS compliant; (4) informed by evidence and (5) having quality for all. We use a case study to illustrate how the co-designed conceptual model stimulated agility and flexibility in workforce and service redesign.

Conclusions

Proactive and situated education of the emerging workforce during policy shift is essential to realise future health workforces that can appropriately and effectively service populations under a variety of changing service and funding structures – as well as their transitions. We argue that collaborative program logic modelling in partnership with key stakeholders including existing workforce can be useful for broad purposes of workforce (re)design in diverse contexts.

COVID-19, Alcohol Consumption and Stockpiling Practises in Midlife Women: Repeat Surveys During Lockdown in Australia and the United Kingdom

Introduction: This project examined the impact of COVID-19 and associated restrictions on alcohol practises (consumption and stockpiling), and perceptions of health risk among women in midlife (those aged 45–64 years).

Methods: We collected online survey data from 2,437 midlife women in the United Kingdom (UK) and Australia in May 2020, recruited using a commercial panel, in the early days of mandated COVID-19 related restrictions in both countries. Participants were surveyed again (N = 1,377) in July 2020, at a time when COVID-19 restrictions were beginning to ease. The surveys included the Alcohol Use Disorder Identification Test—Consumption (AUDIT-C) and questions alcohol stockpiling. Analysis involved a range of univariate and multivariate techniques examining the impact of demographic variables and negative affect on consumption and acquisition outcomes.

Results: In both surveys (May and July), UK women scored higher than Australian women on the AUDIT-C, and residence in the UK was found to independently predict stockpiling of alcohol (RR: 1.51; 95% CI: 1.20, 1.91). Developing depression between surveys (RR: 1.53; 95% CI: 1.14, 2.04) and reporting pessimism (RR: 1.42; 95% CI: 1.11, 1.81), and fear/anxiety (RR: 1.33; 95% CI: 1.05, 1.70) at the beginning of the study period also predicted stockpiling by the end of the lockdown. Having a tertiary education was protective for alcohol stockpiling at each time point (RR: 0.69; 95% CI: 0.54, 0.87).

Conclusions: COVID-19 was associated with increases in risky alcohol practises that were predicted by negative emotional responses to the pandemic. Anxiety, pessimism and depression predicted stockpiling behaviour in UK and Australian women despite the many demographic and contextual differences between the two cohorts. Given our findings and the findings of others that mental health issues developed or were exacerbated during lockdown and may continue long after that time, urgent action is required to address a potential future pandemic of alcohol-related harms.

Social Class and Changes in Australian Women's Affect and Alcohol Consumption During COVID-19

Introduction: Before the pandemic, mid-life women in Australia were among the "heaviest" female alcohol consumers, giving rise to myriad preventable health risks. This paper uses an innovative model of social class within a sample of Australian women to describe changes in affective states and alcohol consumption patterns across two time points during COVID-19. Methods: Survey data were collected from Australian mid-life women (45-64 years) at two time points during COVID-19-May 2020 (N = 1,218) and July 2020 (N = 799). We used a multi-dimensional model for measuring social class across three domains-economic capital (income, property and assets), social capital (social contacts and occupational prestige of those known socially), and cultural capital (level of participation in various cultural activities). Latent class analysis allowed comparisons across social classes to changes in affective states and alcohol consumption patterns reported at the two time points using alcohol consumption patterns as measured by the Alcohol Use Disorders Identification Test-Consumption (AUDIT-C) and its component items. Results: Seven social classes were constructed, characterized by variations in access to capital. Affective states during COVID-19 differed according to social class. Comparing between the survey time points, feeling fearful/anxious was higher in those with high economic and cultural capital and moderate social capital ("emerging affluent"). Increased depression was most prominent in the class characterized by the highest volumes of all forms of capital ("established affluent"). The social class characterized by the least capital ("working class") reported increased prevalence of uncertainty, but less so for feeling fearful or anxious, or depressed. Women's alcohol consumption patterns changed across time during the pandemic. The "new middle" class-a group characterized by high social capital (but contacts with low prestige) and minimal economic capital-had increased AUDIT-C scores. Conclusion: Our data shows the pandemic impacted women's negative affective states, but not in uniform ways according to class. It may explain increases in alcohol consumption among women in the emerging affluent group who experienced increased feelings or fear and anxiety during the pandemic. This nuanced understanding of the vulnerabilities of sub-groups of women, in respect to negative affect and alcohol consumption can inform future pandemic policy responses designed to improve mental health and reduce the problematic use of alcohol. Designing pandemic responses segmented for specific audiences is also aided by our multi-dimensional analysis of social class, which uncovers intricate differences in affective states amongst sub-groups of mid-life women.

Evaluation of 15 years of modeled atmospheric oxidized nitrogen compounds across the contiguous United States

Atmospheric nitrogen oxide and nitrogen dioxide (NO + NO2, together termed as NO X ) estimates from annual photochemical simulations for years 2002-2016 are compared to surface network measurements of NO X and total gas-phase-oxidized reactive nitrogen (NO Y ) to evaluate the Community Multiscale Air Quality (CMAQ) modeling system performance by U.S. region, season, and time of day. In addition, aircraft measurements from 2011 Deriving Information on Surface Conditions from Column and Vertically Resolved Observations Relevant to Air Quality are used to evaluate how emissions, chemical mechanism, and measurement uncertainty each contribute to the overall model performance. We show distinct seasonal and time-of-day patterns in NO X performance. Summertime NO X is overpredicted with bimodal peaks in bias during early morning and evening hours and persisting overnight. The summertime morning NO X bias dropped from between 28% and 57% for earlier years (2002-2012) to between -2% and 7% for later years (2013-2016). Summer daytime NO X tends to be unbiased or underpredicted. In winter, the evening NO X overpredictions remain, but NO X is unbiased or underpredicted overnight, in the morning, and during the day. NO X overpredictions are most pronounced in the Midwestern and Southern United States with Western regions having more of a tendency toward model underpredictions of NO X . Modeled NO X performance has improved substantially over time, reflecting updates to the emission inputs and the CMAQ air quality model. Model performance improvements are largest for years simulated with CMAQv5.1 or later and for emission inventory years 2014 and later, coinciding with reduced onroad NO X emissions from vehicles with newer emission control technologies and improved treatment of chemistry, deposition, and vertical mixing in CMAQ. Our findings suggest that emissions temporalization of specific mobile source sectors have a small impact on model performance, while chemistry updates improve predictions of NO Y but do not improve summertime NO X bias in the Baltimore/DC area. Sensitivity runs performed for different locations across the country suggest that the improvement in summer NO X performance can be attributed to updates in vertical mixing incorporated in CMAQv5.1.

Alcohol Consumption and Perceptions of Health Risks During COVID-19: A Qualitative Study of Middle-Aged Women in South Australia

Australian women's alcohol consumption has increased in frequency during COVID-19. Research suggests this is to cope with stress resulting from the pandemic and COVID-19 countermeasures that require social distancing. This is a critical public health concern because increased alcohol consumption, even for a short period, increases the myriad longer-term health risks associated with cumulative exposure to alcohol. This paper provides unique qualitative evidence of how health risk perceptions are re-focused toward the shorter-term during the pandemic, through analysis of interviews with 40 middle-aged Australian women (aged 45-64) representing a range of self-perceived drinking status' ("occasional"/"light"/"moderate"/"heavy") before and then during the pandemic (n = 80 interviews). Our analysis captures women's risk horizons drifting away from the uncertain longer-term during COVID-19, toward the immediate need to "get through" the pandemic. We show how COVID-19 has increased the perceived value of consuming alcohol among women, particularly when weighed up against the social and emotional "costs" of reducing consumption. Our findings have implications for the delivery of alcohol-related health risk messages designed for middle-aged women both during, and into the recovery phases of the pandemic, who already consume more alcohol and experience more alcohol-related health risk than women in other age groups.

Improved Estimation of Trends in U.S. Ozone Concentrations Adjusted for Interannual Variability in Meteorological Conditions

Daily maximum 8-hour average (MDA8) ozone (O₃) concentrations are well-known to be influenced by local meteorological conditions, which vary across both daily and seasonal temporal scales. Previous studies have adjusted long-term trends in O₃ concentrations for meteorological effects using various statistical and mathematical methods in order to get a better estimate of the long-term changes in O₃ concentrations due to changes in precursor emissions such as nitrogen oxides (NO_X) and volatile organic compounds (VOCs). In this work, the authors present improvements to the current method used by the United States Environmental Protection Agency (US EPA) to adjust O₃ trends for meteorological influences by making refinements to the input data sources and by allowing the underlying statistical model to vary locally using a variable selection procedure. The current method is also expanded by using a quantile regression model to adjust trends in the 90^th and 98^th percentiles of the distribution of MDA8 O₃ concentrations, allowing for a better understanding of the effects of local meteorology on peak O₃ levels in addition to seasonal average concentrations. The revised method is used to adjust trends in the May to September mean, 90^th percentile, and 98^th percentile MDA8 O₃ concentrations at over 700 monitoring sites in the U.S. for years 2000 to 2016. The utilization of variable selection and quantile regression allow for a more in-depth understanding of how weather conditions affect O₃ levels in the U.S. This represents a fundamental advancement in our ability to understand how interannual variability in weather conditions in the U.S. may impact attainment of the O₃ National Ambient Air Quality Standards (NAAQS).

Impact of dimethylsulfide chemistry on air quality over the Northern Hemisphere

We implement oceanic dimethylsulfide (DMS) emissions and its atmospheric chemical reactions into the Community Multiscale Air Quality (CMAQv53) model and perform annual simulations without and with DMS chemistry to quantify its impact on tropospheric composition and air quality over the Northern Hemisphere. DMS chemistry enhances both sulfur dioxide (SO2) and sulfate (S O 4 2 - ) over seawater and coastal areas. It enhances annual mean surface SO2 concentration by +46 pptv andS O 4 2 - by +0.33 μg/m3 and decreases aerosol nitrate concentration by -0.07 μg/m3 over seawater compared to the simulation without DMS chemistry. The changes decrease with altitude and are limited to the lower atmosphere. Impacts of DMS chemistry onS O 4 2 - are largest in the summer and lowest in the fall due to the seasonality of DMS emissions, atmospheric photochemistry and resultant oxidant levels. Hydroxyl and nitrate radical-initiated pathways oxidize 75% of the DMS while halogen-initiated pathways oxidize 25%. DMS chemistry leads to more acidic particles over seawater by decreasing aerosol pH. IncreasedS O 4 2 - from DMS enhances atmospheric extinction while lower aerosol nitrate reduces the extinction so that the net effect of DMS chemistry on visibility tends to remain unchanged over most of the seawater.

Impact of school-based physical activity interventions in primary schools: measuring what matters

Background

A growing number of small studies suggest that school-based physical activity initiatives can help children achieve the recommended 60 minutes of physical activity per day. However, the heterogeneity of outcomes and measures used in small studies prevents pooling of results to demonstrate whether short-term health benefits are sustained. Qualitative studies suggest many benefits that are not represented by outcomes in trials to date. The aim of this study was to generate a list of outcomes that have been studied to develop a core outcome set (COS) acceptable to key stakeholders for future studies evaluating school-based physical activity initiatives.

Methods

We searched six databases (MEDLINE, EMBASE, PsycINFO, CINAHL, CENTRAL and Cochrane Database of Systematic Reviews) systematically for reviews of school-based physical activity interventions, and extracted relevant studies to identify the outcomes and measures used in each paper. A long list was generated from the literature and a previous workshop with stakeholders. This study is registered with COMET (#1322), and with PROSPERO (CRD42019146621).

Results

75/121 cited studies drawn from 53/2409 reviews met our inclusion criteria. We grouped 65 outcomes into 3 domains: (i) physical activity and health (ii) social and emotional health, and (iii) educational attainment. We will conduct two Delphi survey rounds with four stakeholder groups (health professionals, researchers, educators and parents) to rate the importance of each outcome. A core outcome set will be generated from a consensus process.

Conclusions

There is currently a large variation of outcomes and measures studied that precludes evidence synthesis of the impact of school-based physical activity interventions. Consensus methods are needed to focus research on the outcomes that matter the most to key stakeholders and to provide tools for future studies to assess long-term impact.

Key messages

Variations in outcomes studied precludes evidence synthesis of SBPA intervention impacts. A core outcome set is needed to ensure future SBPA interventions measure outcomes that matter the most.

Opportunities for Technology-Assisted Healthy Ageing in a Local Government Context

Current legislation aims to enable older Australians to age in place, and puts public healthcare within the remit of local governments. As Australia's population ages, local governments will need to explore new methods of service delivery in order to meet the increasing need for services that promote healthy ageing. Information technology (IT) may provide one such solution, however older Australian adults are reported to have low levels of technology use. In this simple descriptive qualitative study, focus groups with local government staff and community-dwelling older adults explored their perspectives regarding: a) IT solutions that councils could use to promote community-based healthy ageing, and (b) the enablers and challenges for adopting such solutions. Twenty-four adults participated in focus groups, and eleven of these adults also provided written data in response to visual prompts. Field notes were recorded by attending researchers. These three data sources were combined through narrative synthesis. Local government staff and community-dwellers alike perceived the utility of IT solutions in connecting community members, and connecting people to services (such as transport and providers of health information). While local government staff identified that IT solutions could provide benefits to the council when implemented in conjunction with existing services (e.g., to track data and identify information about community engagement and needs), community-dwellers placed stronger emphasis on adopting technology which had a clear purpose for its use. Due to limited digital literacy and some ambivalence towards embracing technology, IT solutions should be implemented with support to increase digital literacy, be widely advertised, and be centered in community needs. Personas have been generated and provided as possible case studies for technology adoption.

Impact of transition to an individualised funding model on allied health support of participation opportunities

Introduction: The National Disability Insurance Scheme is the new consumer-controlled funding system for people with disability in Australia, and is expected to enhance participation outcomes of people with disability. This research explored participation opportunities for people with disability during the formative period of transition to the scheme, through stakeholder accounts of changes in allied health service contexts.Materials and methods: Qualitative data were generated during interviews, workshops and meetings with industry, policy, practice and education stakeholders involved in scheme services. Inductive coding explored key themes within the data. The International Classification of Functioning model was then applied as a deductive coding framework to illuminate how the scheme was perceived to be impacting participation opportunities for recipients of scheme funding.Results and discussion: Using the International Classification of Functioning helped us illuminate whether changes resulting from scheme transition posed participation opportunities or barriers for scheme recipients. Research participants often framed these changes negatively, even when examples suggested that changes had removed participation barriers for scheme recipients. Some participants viewed changes as obstructing equitable and quality professional practice. We explore potential opportunities to resolve tensions that also optimise the participation outcomes of individuals who receive services through individualised funding.IMPLICATIONS FOR REHABILITATIONThe introduction of individualised funding has removed barriers to participation for many National Disability Insurance Scheme recipients.Efforts must be made to build the trust of stakeholders involved in National Disability Insurance Scheme service provision regarding how fee-for-service funding can lead to good participation outcomes for scheme recipients.Transparency around the shared processes of clinical governance and equitable service access operating in Australia's individualized disability funding scheme are suggested to build trust.A visible commitment to maintaining a broad range of services is also indicated to build trust for stakeholders involved in the scheme.

Monitoring the 'diabetes epidemic': A framing analysis of United Kingdom print news 1993-2013

INTRODUCTION

The view that we are in the midst of a global diabetes epidemic has gained considerable ground in recent years and is often linked to the prior 'obesity epidemic'. This research explored how the diabetes epidemic was represented in United Kingdom (UK) news over the same time period that the obesity epidemic was widely reported. The research was motivated by a sociological interest in how postmodern 'epidemics' synergise with each other amidst broader political, economic, moral and sociocultural discourses.

METHOD

We analysed three time-bound samples of UK news articles about diabetes: 1993 (n = 19), 2001 (n = 119) and 2013 (n = 324). Until now, UK media has had the least attention regarding portrayal of diabetes. We adopted an empathically neutral approach and used a dual method approach of inductive thematic analysis and deductive framing analysis. The two methods were triangulated to produce the findings.

RESULTS

Framing of diabetes moved from medical in 1993 to behavioural in 2001, then societal in 2013. By 2001 obesity was conceptualised as causal to diabetes, rather than a risk factor. Between 2001 and 2013 portrayals of the modifiable risk factors for diabetes (i.e. diet, exercise and weight) became increasingly technical. Other risk factors like age, family history and genetics faded during 2001 and 2013, while race, ethnicity and culture were positioned as states of 'high risk' for diabetes. The notion of an 'epidemic' of diabetes 'powered up' these concerns from an individual problem to a societal threat in the context of obesity as a well-known health risk.

DISCUSSION AND CONCLUSION

Portraying diabetes and the diabetes epidemic as anticipated consequences of obesity enlivens the heightened awareness to future risks in everyday life brought about during the obesity epidemic. The freeform adoption of the 'epidemic' term in contemporary health discourse appears to foster individual and societal dependence on biomedicine, giving it political, economic and divisive utility.

Using a nominal group technique to approach consensus on a resilience intervention for smoking cessation in a lower socioeconomic population

Background

Smoking prevalence remains inequitably high for lower SES (socioeconomic status) populations. The psychosocial interactive model of resilience theorises that resilience might be ‘switched on’ in order to support and/or maintain smoking cessation for these populations. This study aimed to develop a Resilience Intervention for Smoking Cessation (RISC) through reviewing the extant literature around efficacious interventions for smoking cessation. Deliberative democracy principles were then used to understand lay perspectives regarding this potential smoking cessation program.

Methods

Public health databases were searched to find efficacious psycho-social resilience interventions in the peer-reviewed literature for smoking cessation amongst lower SES populations. Potential components for RISC were selected based on evidence within the literature for their effectiveness. We then employed the Nominal Group Technique (NGT) to create discussion and consensus on the most socially appropriate and feasible components from the perspective of smokers from low SES areas. The NGT included 16 people from a lower SES population in southern metropolitan Adelaide who indicated they were seriously contemplating quitting smoking or had recently quit. Data were collected from multiple Likert ratings and rankings of the interventions during the NGT workshop and analysed descriptively. The Wilcoxon signed-ranked test was used where appropriate. Qualitative data were collected from participant reflections and group discussion, and analysed thematically.

Results

Six smoking cessation interventions, likely to enhance resilience, were selected as potential constituents for RISC: mindfulness training; setting realistic goals; support groups; smoke free environments; mobile phone apps; and motivational interviewing. Consensus indicated that mindfulness training and setting realistic goals were the most acceptable resilience enhancing interventions, based on perceived usefulness and feasibility.

Conclusions

This research applied principles from deliberative democracy in order to illuminate lay knowledge regarding an appropriate and acceptable smoking cessation resilience program for a lower SES population. This process of collaborative and complex knowledge-generation is critically important to confront inequities as an ongoing challenge in public health, such as smoking cessation for disadvantaged groups. Further research should involve development and trial of this resilience program.

Innovating Qualitative Framing Analysis for Purposes of Media Analysis Within Public Health Inquiry

Public health is said to lack methodological diversity and creativity in media analysis. Although the framing paradigm offers important conceptual and operational insights for undertaking media analysis in public health research, frames are described as "elusive" to measure with their analysis a "methodological black box." With this article, we aim to foster creative thinking around media analysis in public health and to make the "black box" of framing analysis more transparent, by illustrating the innovation and application of a qualitative framing analysis technique in original public health research. We provide a "how to" guide for this framing analysis method and use data to illustrate methodological challenges encountered during the research. The findings drawn from this method are contrasted with findings gained from thematic analysis applied to the same data. The article concludes by considering the benefits of this type of framing analysis within public health scholarship.

Alcohol and breast cancer risk: Middle-aged women's logic and recommendations for reducing consumption in Australia

BACKGROUND

We aimed to understand the factors shaping alcohol consumption patterns in middle-aged women (45-64), and to identify participant-driven population- and policy-level strategies that may be used to addresses alcohol consumption and reduce breast cancer risk.

METHODS

Semi-structured interviews (n = 35) were conducted with 'middle-aged' women conversant in English and living in South Australia with no history of breast cancer diagnosis. Data were deductively coded using a co-developed framework including variables relevant to our study objectives. Women were asked about their current level of awareness of the association between alcohol and breast cancer risk, and their personal recommendations for how to decrease consumption in middle-aged Australian women.

RESULTS

Women discussed their previous efforts to decrease consumption, which we drew on to identify preliminary recommendations for consumption reduction. We identified a low level of awareness of alcohol and breast cancer risk, and confusion related to alcohol as a risk for breast cancer, but not always causing breast cancer. Participants suggested that education and awareness, through various means, may help to reduce consumption.

CONCLUSIONS

Participants' description of strategies used to reduce their own consumption lead us to suggest that campaigns might focus on the more salient and immediate effects of alcohol (e.g. on physical appearance and mental health) rather than longer-term consequences. Critical considerations for messaging include addressing the personal, physical and social pleasures that alcohol provides, and how these may differ across socio-demographics.

Influence of bromine and iodine chemistry on annual, seasonal, diurnal, and background ozone: CMAQ simulations over the Northern Hemisphere

Bromine and iodine chemistry has been updated in the Community Multiscale Air Quality (CMAQ) model to better capture the influence of natural emissions from the oceans on ozone concentrations. Annual simulations were performed using the hemispheric CMAQ model without and with bromine and iodine chemistry. Model results over the Northern Hemisphere show that including bromine and iodine chemistry in CMAQ not only reduces ozone concentrations within the marine boundary layer but also aloft and inland. Bromine and iodine chemistry reduces annual mean surface ozone over seawater by 25%, with lesser ozone reductions over land. The bromine and iodine chemistry decreases ozone concentration without changing the diurnal profile and is active throughout the year. However, it does not have a strong seasonal influence on ozone over the Northern Hemisphere. Model performance of CMAQ is improved by the bromine and iodine chemistry when compared to observations, especially at coastal sites and over seawater. Relative to bromine, iodine chemistry is approximately four times more effective in reducing ozone over seawater over the Northern Hemisphere (on an annual basis). Model results suggest that the chemistry modulates intercontinental transport and lowers the background ozone imported to the United States.

Hemodialysis-Associated Febrile Episodes: Surveillance before and after Major Alteration in the Water Treatment System

Surveillance for bacteremic or pyrogenic episodes associated with hemodialysis was undertaken before and after the reconstruction of the water treatment system at our University medical center. The new water system included a holding tank with iodination treatment. The water delivered to individual dialysis stations had only occasional positive bacterial cultures (3 of 21 samples before completion of construction, 2 of 16 samples afterwards) and intermittent detection of endotoxin (6 of 21 samples before completion of construction, 9 of 16 samples afterwards) at monthly sampling. Among 51 individual dialysis treatments (25 patients) before reconstruction and 56 treatments (29 patients), after, only 2 and 3 febrile events were identified, respectively. All of these were associated with underlying infectious illness and not with the hemodialysis procedure itself. Overall, we conclude that pyrogenic episodes associated directly with hemodialysis treatment are infrequent, and that the addition of a water storage tank with iodination treatment does not appear to increase the risk of bacteremia or pyrogenic episodes.

Defining cosmetic surgery

An agreed definition for cosmetic surgery would be helpful for the purposes of discourse on ethics, patient safety, healthcare policy and health economics.  One of the problems with previous attempts at developing a definition is the narrow frame of reference and lack of engagement with the full spectrum of academics and stakeholders.  This review brings together the sociological as well as the surgical literature on the topic of cosmetic surgery and examines societal, ethical and healthcare aspects.  It outlines principles of constructing a definition and presents a provisional definition for further debate, namely:  Cosmetic surgery is defined, for the purposes of a healthcare payer, as any invasive procedure where the primary intention is to achieve what the patient perceives to be a more desirable appearance and where the procedure involves changes to bodily features that have a normal appearance on presentation to the doctor. In contrast, surgery performed with the goal of achieving a normal appearance, where bodily features have an abnormal appearance on presentation due to congenital defects, developmental abnormalities, trauma, infections, tumours or disease does not fall under the definition of cosmetic surgery.  It is a given that “normal appearance” is a subjective notion.  Determining whether patients have a normal or abnormal appearance on presentation will rely on the clinical assessment of the treating doctor.

The impact of US wildland fires on ozone and particulate matter: a comparison of measurements and CMAQ model predictions from 2008 to 2012

Wildland fire emissions are routinely estimated in the US Environmental Protection Agency's National Emissions Inventory, specifically for fine particulate matter (PM_2.5) and precursors to ozone (O₃); however, there is a large amount of uncertainty in this sector. We employ a brute-force zero-out sensitivity method to estimate the impact of wildland fire emissions on air quality across the contiguous US using the Community Multiscale Air Quality (CMAQ) modelling system. These simulations are designed to assess the importance of wildland fire emissions on CMAQ model performance and are not intended for regulatory assessments. CMAQ ver. 5.0.1 estimated that fires contributed 11% to the mean PM_2.5 and less than 1% to the mean O₃ concentrations during 2008-2012. Adding fires to CMAQ increases the number of 'grid-cell days' with PM_2.5 above 35 μg m^-3 by a factor of 4 and the number of grid-cell days with maximum daily 8-h average O₃ above 70 ppb by 14%. Although CMAQ simulations of specific fires have improved with the latest model version (e.g. for the 2008 California wildfire episode, the correlation r = 0.82 with CMAQ ver. 5.0.1 v. r = 0.68 for CMAQ ver. 4.7.1), the model still exhibits a low bias at higher observed concentrations and a high bias at lower observed concentrations. Given the large impact of wildland fire emissions on simulated concentrations of elevated PM_2.5 and O₃, improvements are recommended on how these emissions are characterised and distributed vertically in the model.
