Inhalation of asbestos fibres can cause lung inflammation and the later development of asbestosis, lung cancer, and mesothelioma, and the use of asbestos is banned in many countries. In most countries, large amounts of asbestos exists within building stock, buried in landfills, and in contaminated soil. Mechanical, thermal, and chemical treatment options do exist, but these are expensive, and they are not effective for contaminated soil, where only small numbers of asbestos fibres may be present in a large volume of soil. Research has been underway for the last 20 years into the potential use of microbial action to remove iron and other metal cations from the surface of asbestos fibres to reduce their toxicity. To access sufficient iron for metabolism, many bacteria and fungi produce organic acids, or iron-chelating siderophores, and in a growing number of experiments these have been found to degrade asbestos fibres in vitro. This paper uses the internal transcribed spacer (ITS) and 16S amplicon sequencing to investigate the fungal and bacterial diversity found on naturally-occurring asbestos minerals, asbestos-containing building materials, and asbestos-contaminated soils with a view to later selectively culturing promising species, screening them for siderophore production, and testing them with asbestos fibres in vitro. After filtering, 895 ITS and 1265 16S amplicon sequencing variants (ASVs) were detected across the 38 samples, corresponding to a range of fungal, bacteria, cyanobacterial, and lichenized fungal species. Samples from Auckland (North Island, New Zealand) asbestos cement, Auckland asbestos-contaminated soils, and raw asbestos rocks from Kahurangi National Park (South Island, New Zealand) were comprised of very different microbial communities. Five of the fungal species detected in this study are known to produce siderophores. [ABSTRACT FROM AUTHOR]

Background: Significant progress has been made addressing adolescent health needs in New Zealand, but some areas, such as mental health issues remain, particularly for rangatahi Māori (indigenous Māori young people). Little is known about how contemporary Māori whānau (families) and communities influence health outcomes, health literacy and access to services. Previous nationally representative secondary school surveys were conducted in New Zealand in 2001, 2007 and 2012, as part of the Youth2000 survey series. This paper focuses on a fourth survey conducted in 2019 (https://www.youth19.ac.nz/). In 2019, the survey also included kura kaupapa Māori schools (Māori language immersion schools), and questions exploring the role of family connections in health and wellbeing. This paper presents the overall study methodology, and a weighting and calibration framework in order to provide estimates that reflect the national student population, and enable comparisons with the previous surveys to monitor trends. Methods: Youth19 was a cross sectional, self-administered health and wellbeing survey of New Zealand high school students. The target population was the adolescent population of New Zealand (school years 9–13). The study population was drawn from three education regions: Auckland, Tai Tokerau (Northland) and Waikato. These are the most ethnically diverse regions in New Zealand. The sampling design was two-stage clustered stratified, where schools were the clusters, and strata were defined by kura schools and educational regions. There were four strata, formed as follows: kura schools (Tai Tokerau, Auckland and Waikato regions combined), mainstream-Auckland, mainstream-Tai Tokerau and mainstream-Waikato. From each stratum, 50% of the schools were randomly sampled and then 30% of students from the selected schools were invited to participate. All students in the kura kaupapa schools were invited to participate. In order to make more precise estimates and adjust for differential non-response, as well as to make nationally relevant estimates and allow comparisons with the previous national surveys, we calibrated the sampling weights to reflect the national secondary school student population. Results: There were 45 mainstream and 4 kura schools included in the final sample, and 7,374 mainstream and 347 kura students participated in the survey. There were differences between the sampled population and the national secondary school student population, particularly in terms of sex and ethnicity, with a higher proportion of females and Asian students in the study sample than in the national student population. We calculated estimates of the totals and proportions for key variables that describe risk and protective factors or health and wellbeing factors. Rates of risk-taking behaviours were lower in the sampled population than what would be expected nationally, based on the demographic profile of the national student population. For the regional estimates, calibrated weights yield standard errors lower than those obtained with the unadjusted sampling weights. This leads to significantly narrower confidence intervals for all the variables in the analysis. The calibrated estimates of national quantities provide similar results. Additionally, the national estimates for 2019 serve as a tool to compare to previous surveys, where the sampling population was national. Conclusions: One of the main goals of this paper is to improve the estimates at the regional level using calibrated weights to adjust for oversampling of some groups, or non-response bias. Additionally, we also recommend the use of calibrated estimators as they provide nationally adjusted estimates, which allow inferences about the whole adolescent population of New Zealand. They also yield confidence intervals that are significantly narrower than those obtained using the original sampling weights. [ABSTRACT FROM AUTHOR]

Governments around the world are seeking to slow the spread of Covid-19 by implementing measures that encourage, or mandate, changes in people's behaviour. These changes include the wearing of face masks, social distancing, and testing and self-isolating when unwell. The success of these measures depends on the commitment of individuals to change their behaviour accordingly. Understanding and predicting the motivation of individuals to change their behaviour is therefore critical in assessing the likely effectiveness of these measures in slowing the spread of the virus. In this paper we draw on a novel framework, the I3 Compliance Response Framework, to understand and predict the motivation of residents in Auckland, New Zealand, to comply with measures to prevent the spread of Covid-19. The Framework is based on two concepts. The first uses the involvement construct to predict the motivation of individuals to comply. The second separates the influence of the policy measure from the influence of the policy outcome on the motivation of individuals to comply. In short, the Framework differentiates between the strength of individuals' motivation and their beliefs about the advantages and disadvantages of policy outcomes and policy measures. We found this differentiation was useful in predicting an individual's possible behavioural responses to a measure and discuss how it could assist government agencies to develop strategies to enhance compliance.

The complex interactions and ruptures between contemporary settler colonialism, environmental ethics, and Indigenous rights and worldviews often emerge in projects of civil engineering. The continued capture, control and burial of natural water courses in Aotearoa-New Zealand is a case in point, and exemplifies a failure to stay abreast of evolving understandings and renewed relationships we seek with our waterways, our ancestors. Wai-Horotiu stream used to run down what is now Queen Street, the main road in Auckland, Aotearoa-New Zealand's largest city. Treasured by Māori as a source of wai (water) and mahinga kai (food), it is also the home of Horotiu, a taniwha or ancestral guardian--a literal 'freshwater body'. However, as Tāmaki-Makaurau transitioned into Auckland city, Wai-Horotiu became denigrated; used as an open sewer by early settlers before being buried alive in the colonial process. How, now, can we know this buried waterway? Te Awa Tupua Act 2017 that affords the Whanganui River juristic personality and moral considerability offers one possible solution. It acknowledges that waterways, incorporating all their physical and metaphysical elements, exist in existential interlinks with Māori as part of their whakapapa (genealogical networks). This paper asks, can a corresponding and appropriate ethics of association and care be fostered in and expressed by the political descendants of British settlers (Pākehā) and later immigrants who live here under the auspices established by Te Tiriti o Waitangi in 1840? Here is a conversation between a Māori earth systems scientist and a Pākehā interdisciplinary scholar. Where Hikuroa speaks from and to direct whakapapa connections, beginning with pepeha, Lythberg's narrative springboards from public art projects that facilitate more ways of knowing Wai-Horotiu. Together, we contend that a regard for Indigenous relationships with water can guide best practice for us all, and propose that creative practices can play a role in attaching people to place, and to waterways.

Background: Loss of cognitive function is a significant issue as the world's population ages. Preserving cognitive function maintains independence in older adults bringing major societal and financial benefits. Lifestyle factors such as diet are modifiable risk factors, which may help preserve cognitive function. Most nutrition research aimed at preserving cognitive function and metabolic health has focussed on individual nutrients and foods, not allowing for food combinations and interactions. A dietary pattern approach considers the entire diet including its complexity. Previous research investigating dietary patterns and cognitive function has not always considered relevant covariates such as physical activity and the Apolipoprotein E genotype, which are known to have associations with cognitive function. The aim of the REACH (Researching Eating, Activity and Cognitive Health) study is to investigate associations between dietary patterns, cognitive function and metabolic syndrome, accounting for a range of covariates.Methods: This cross-sectional study design will recruit older, community-living adults (65-74 years) from Auckland, New Zealand. Dietary data will be collected via a 109-item food frequency questionnaire validated using a 4-day food record. Cognitive function will be assessed using the Montreal Cognitive Assessment (paper based) and the Computerised Mental Performance Assessment System (COMPASS) - a testing suite covering six domains. Additional data will include genetic (Apolipoprotein E ε4) and biochemical markers (fasting glucose, HbA1c, lipids profile), anthropometric measurements (weight, height, waist and hip circumference, body composition using dual X-ray absorptiometry), blood pressure, physical activity (International Physical Activity Questionnaire - short form) and health and demographics (questionnaire). Dietary patterns will be derived by principal component analysis. Associations between cognitive function and dietary patterns will be examined using multiple regression analysis. Covariates and interaction factors will include age, education, socio-economic status, physical activity, Apolipoprotein E ε4 genotype, family history of dementia or cognitive impairment, and lifestyle factors. Differences between participants with and without metabolic syndrome will also be examined.Discussion: This study will bring new knowledge regarding associations between dietary patterns and cognitive function and metabolic health in older adults living in New Zealand. This is important for developing nutrition related recommendations to help older adults maintain cognitive function. [ABSTRACT FROM AUTHOR]

Introduction: Not surprisingly given their multi-component nature, initiatives to improve integrated care often evolve to find the best way to bring about change. This paper provides an example of how an evaluation evolved alongside such an initiative designed to better integrate care across primary, community and hospital services in South Auckland, New Zealand. Theory and methods: Using the explanatory power of a realist evaluative approach, theories of new ways of working that might be prompted by the initiative were explored in: (i) interviews with stakeholders in 2012 and 2015, (ii) online surveys of general practices and local care organisations, and (iii) a purposive sample of ten general practices. Results: The results highlighted the institutional contexts that led to difficulties in implementing population health initiatives. They also revealed that changes in work practices focussed mostly on activities that improved the coordination of care for individuals at risk of hospital admissions. Discussion: Multi-component complex interventions can vary in their delivery and be vulnerable to one or more components not being implemented as originally intended. In the case of this intervention, the move towards strengthening local relationships arose when contractual arrangements stalled. Realist evaluative approaches offer a logic that helps unpick the complexity of the relationships and politics in play, and uncover the assumptions made by those developing, implementing and assessing health service changes. Conclusion: Given the multi-component and evolving nature of initiatives seeking to better integrate care, the realist evaluative emphasis on surfacing early the theories to explain how change is expected to occur helps overcome the challenge of evaluating "a moving target".
