Item Modeling evacuation decisions in the 2019 Kincade fire in CaliforniaKuligowski, ED; Zhao, X; Lovreglio, R; Xu, N; Yang, K; Westbury, A; Nilsson, D; Brown, NItem Risk perception and knowledge of protective measures for flood risk planning. The case study of Brindisi (Puglia region)(2022-09-01) Santoro, S; Totaro, V; Lovreglio, R; Camarda, D; Iacobellis, V; Fratino, UFloods are among the most frequent natural hazards, and flood risk management is a paramount task when planning solutions to reduce their impact on communities. In the last decades, policy makers' actions for flood risk management have been redirected from purely physical self-protective measures towards integrated management strategies by including social components. Assessing flood risk perception and the level of knowledge of citizens regarding protective measures is becoming a pillar for generating innovative flood integrated management strategies. This study aims to highlight multiple aspects which can influence flood risk management in urban areas, providing a preliminary assessment of citizens’ flood risk perception and knowledge of protective measures. Proposed methodology is based on E-survey in order to gather data and Mann-Whitney and Kruskal-Wallis tests to analyze them and has been applied to the case study of Brindisi (Puglia region, Southern Italy). The results suggest that flood risk perception depends on intrinsic components of individuals, mainly related to trust in public strategies and risk communication. It depends on hazard proximity but is uniformly distributed over the whole city, demonstrating that the perception of flood risk can not be related only to river floods. Knowledge of protective measures appears uniformly low by category of citizens and territorial area, particularly for teenagers. The methodological approach has allowed to bring out how the different nature of floods could produce a spatial and social heterogeneity in citizens’ flood risk perception and knowledge of protective measures, revealing latent risk features useful for supporting flood risk planning.Item 2021 Assessment of New Zealand district health boards' institutional healthy food and drink policies: the HealthY Policy Evaluation (HYPE) study(Pasifika Medical Association Group (PMAG), 2022-08-19) Gerritsen S; Kidd B; Rosin M; Shen S; Mackay S; Te Morenga L; Mhurchu CNAIM: To assess adoption of the voluntary National Healthy Food and Drink Policy (NHFDP) and the alignment of individual institutional healthy food and drink policies with the NHFDP. METHOD: All 20 district health boards (DHBs) and two national government agencies participated. Policies of those organisations that had not fully adopted the NHFDP were assessed across three domains: nutrition standards; promotion of a healthy food and beverages environment; and policy communication, implementation and evaluation. Three weighted domain scores out of 10, and a total score out of 30 were calculated. RESULTS: Nine of the 22 organisations reported adopting the NHFDP in full. Of the remaining 13, six referred to the NHFDP when developing their institutional policy and three were working toward full adoption of the NHFDP. Mean scores (SD) were 8.7 (1.0), 6.1 (2.6) and 3.8 (2.2) for the three domains, and 18.6 (4.8) in total. Most individual institutional policies were not as comprehensive as the NHFDP. However, some contained stricter/additional clauses that would be useful to incorporate into the NHFDP. CONCLUSION: Since a similar policy analysis in 2018, most DHBs have adopted the NHFDP and/or strengthened their own nutrition policies. Regional inconsistency remains and a uniform mandatory NHFDP should be implemented that incorporates improvements identified in individual institutional policies.Item Dietary patterns associated with meeting the WHO free sugars intake guidelines(Cambridge University Press, 2020-06) Steele C; Eyles H; Te Morenga L; Ni Mhurchu C; Cleghorn COBJECTIVE: Emerging evidence suggests that free sugars intake in many countries exceeds that recommended by the WHO. However, information regarding real-world dietary patterns associated with meeting the WHO free sugars guidelines is lacking. The current study aimed to determine dietary patterns associated with meeting the guidelines to inform effective free sugars reduction interventions in New Zealand (NZ) and similar high-income countries. DESIGN: Dietary patterns were derived using principal component analysis on repeat 24-h NZ Adult Nutrition Survey dietary recall data. Associations between dietary patterns and the WHO guidelines (<5 and <10 % total energy intake) were determined using logistic regression analyses. SETTING: New Zealand. PARTICIPANTS: NZ adults (n 4721) over 15 years old. RESULTS: Eight dietary patterns were identified: 'takeaway foods and alcohol' was associated with meeting both WHO guidelines; 'contemporary' was associated with meeting the <10 % guideline (males only); 'fast foods, sugar-sweetened beverages and dessert', 'traditional' and 'breakfast foods' were negatively associated with meeting both guidelines; 'sandwich' and 'snack foods' were negatively associated with the <5 % guideline; and 'saturated fats and sugar' was negatively associated with the <10 % guideline. CONCLUSIONS: The majority of NZ dietary patterns were not consistent with WHO free sugars guidelines. It is possible to meet the WHO guidelines while consuming a healthier ('contemporary') or energy-dense, nutrient-poor ('takeaway foods and alcohol') diet. However, the majority of energy-dense patterns were not associated with meeting the guidelines. Future nutrition interventions would benefit from focusing on establishing healthier overall diets and reducing consumption and free sugars content of key foods.Item What helps and hinders metformin adherence and persistence: a qualitative study exploring the views of people with type 2 diabetes(New Zealand Medical Association, 2021-06-04) Parkin L; Maclennan K; Te Morenga L; Inder M; Moata'ane LAIM: To explore the views of people with type 2 diabetes who had initiated metformin monotherapy about what influences adherence and persistence. METHODS: We recruited participants through primary care, using purposive sampling, and undertook face-to-face, audio-recorded, semi-structured interviews with 10 Māori, 10 Pacific, and 10 non-Māori non-Pacific patients who had started metformin monotherapy for type 2 diabetes within the previous two years. A thematic analysis was undertaken using the Theory of Planned Behaviour as the overall theoretical framework. RESULTS: The perceived benefits of taking metformin included improving glycaemic control, preventing or slowing the progression of type 2 diabetes, and avoiding serious complications. Side effects (predominantly gastrointestinal) were the most commonly cited disadvantage. Participants employed a variety of strategies to help them take metformin regularly. Key reasons for initial sub-optimal adherence and persistence were side effects and not accepting the diagnosis of type 2 diabetes. Subsequently, omitting to take tablets was commonly unintentional (due to 'forgetfulness'). For many Pacific participants, changes in routine related to community and church events, or shift work, contributed to sub-optimal adherence. Some Māori participants would have preferred to use traditional medicines. CONCLUSION: We identified a number of factors within the scope of healthcare services that may assist healthcare providers to focus on, and address, some of the issues that appear to be of primary importance to people when they are prescribed metformin.Item Food, nutrition and cancer: perspectives and experiences of New Zealand cancer survivors(New Zealand Medical Association, 2021-11-12) Peniamina R; Davies C; Moata'ane L; Signal L; Tavite H; Te Morenga L; McLean RAIM: This research sought to understand and describe cancer survivors' perspectives and post-diagnosis experiences of food and nutrition, with a particular focus on barriers to healthy eating, health equity, and Māori and Pacific perspectives. METHOD: Data were collected using semi-structured interviews with cancer survivors from three different ethnic groups (Māori, Pacific Peoples, and New Zealand European). Thematic analysis was undertaken to identify both similar and contrasting experiences and perspectives in relation to topics of interest. Data analysis also sought to identify any trends indicating differences between ethnic groups. RESULTS: Limited awareness of the role nutrition has in cancer recovery or prevention, combined with little or no access to nutrition advice/support, meant that healthy dietary change was not a focus for some cancer survivors in this study, whereas others invested considerable time and money accessing nutrition information and support outside of cancer care services. Financial limitations (eg, cost of healthy food and low income) and lack of practical support were also important barriers to post-diagnosis healthy eating. CONCLUSION: There is a need for more widely available cancer-specific nutrition advice and support in New Zealand. Interventions to address financial barriers and increase access to cancer-related nutrition advice and support have the potential to improve cancer outcomes and reduce inequities in cancer outcomes.Item Barriers and facilitators to implementation of healthy food and drink policies in public sector workplaces: a systematic literature review.(19/06/2023) Rosin M; Mackay S; Gerritsen S; Te Morenga L; Terry G; Ni Mhurchu CCONTEXT: Many countries and institutions have adopted policies to promote healthier food and drink availability in various settings, including public sector workplaces. OBJECTIVE: The objective of this review was to systematically synthesize evidence on barriers and facilitators to implementation of and compliance with healthy food and drink policies aimed at the general adult population in public sector workplaces. DATA SOURCES: Nine scientific databases, 9 grey literature sources, and government websites in key English-speaking countries along with reference lists. DATA EXTRACTION: All identified records (N = 8559) were assessed for eligibility. Studies reporting on barriers and facilitators were included irrespective of study design and methods used but were excluded if they were published before 2000 or in a non-English language. DATA ANALYSIS: Forty-one studies were eligible for inclusion, mainly from Australia, the United States, and Canada. The most common workplace settings were healthcare facilities, sports and recreation centers, and government agencies. Interviews and surveys were the predominant methods of data collection. Methodological aspects were assessed with the Critical Appraisal Skills Program Qualitative Studies Checklist. Generally, there was poor reporting of data collection and analysis methods. Thematic synthesis identified 4 themes: (1) a ratified policy as the foundation of a successful implementation plan; (2) food providers' acceptance of implementation is rooted in positive stakeholder relationships, recognizing opportunities, and taking ownership; (3) creating customer demand for healthier options may relieve tension between policy objectives and business goals; and (4) food supply may limit the ability of food providers to implement the policy. CONCLUSIONS: Findings suggest that although vendors encounter challenges, there are also factors that support healthy food and drink policy implementation in public sector workplaces. Understanding barriers and facilitators to successful policy implementation will significantly benefit stakeholders interested or engaging in healthy food and drink policy development and implementation.

The study population was made up of 1 004 795 residents from 205 001 New Zealand houses that received an insulation subsidy though a national Energy Efficiency and Conservation Authority program. A difference-in-difference model compared changes in the number of prescriptions dispensed for respiratory illness post- insulation to a control population over the same timeframe. New prescribing of chronic respiratory disease medication at follow-up was used to compare incidence risk ratios between intervention and control groups. Chronic respiratory disease incidence was significantly lower in the intervention group at follow-up: odds ratio 0.90 (95% CI: 0.86-0.94). There was also a 4% reduction in medication dispensed for treating exacerbations of chronic respiratory disease symptoms in the intervention group compared with the control group: relative rate ratio (RRR) 0.96 (95% CI: 0.96-0.97). There was no change in medication dispensed to prevent symptoms of chronic respiratory disease RRR: 1,00 (95% CI: 0.99-1.00). These findings support home insulation interventions as a means of improving respiratory health outcomes.Item A novel gyrovirus is abundant in yellow-eyed penguin (Megadyptes antipodes) chicks with a fatal respiratory disease.(2023-02) Wierenga JR; Morgan KJ; Hunter S; Taylor HS; Argilla LS; Webster T; Dubrulle J; Jorge F; Bostina M; Burga L; Holmes EC; McInnes K; Geoghegan JLYellow-eyed penguins (Megadyptes antipodes), or hoiho in te reo Māori, are predicted to become extinct on mainland Aotearoa New Zealand in the next few decades, with infectious disease a significant contributor to their decline. A recent disease phenomenon termed respiratory distress syndrome (RDS) causing lung pathology has been identified in very young chicks. To date, no causative pathogens for RDS have been identified. In 2020 and 2021, the number of chick deaths from suspected RDS increased four- and five-fold, respectively, causing mass mortality with an estimated mortality rate of >90%. We aimed to identify possible pathogens responsible for RDS disease impacting these critically endangered yellow-eyed penguins. Total RNA was extracted from tissue samples collected during post-mortem of 43 dead chicks and subject to metatranscriptomic sequencing and histological examination. From these data we identified a novel and highly abundant gyrovirus (Anelloviridae) in 80% of tissue samples. This virus was most closely related to Gyrovirus 8 discovered in a diseased seabird, while other members of the genus Gyrovirus include Chicken anaemia virus, which causes severe disease in juvenile chickens. No other exogenous viral transcripts were identified in these tissues. Due to the high relative abundance of viral reads and its high prevalence in diseased animals, it is likely that this novel gyrovirus is associated with RDS in yellow-eyed penguin chicks.Item Impact of high- and low-flow nebulized saline on airway hydration and mucociliary transport(European Respiratory Society, 2023) Kelly S; Valentine M; Chua WH; Tatkov SBACKGROUND: Nebulised drugs, including osmotic agents and saline, are increasingly used during noninvasive respiratory support, including nasal high-flow therapy. The authors conducted an in vitro study to compare the hydration effect of nebulised isotonic 0.9% and hypertonic 7.0% saline on mucociliary transport. METHODS: In a perfused organ bath, 10 sheep tracheas were exposed to 7.5 mL nebulised 0.9% and 7.0% saline entrained into heated (38°C) and humidified air delivered at high and low flow (20 and 7 L·min-1, respectively). Simultaneous measurements of the airway surface liquid height, mucus transport velocity, cilia beat frequency and surface temperature were made over time. The data are presented as mean±sd. RESULTS: The airway surface liquid height increased significantly with both 0.9% and 7.0% saline: at low-flow by 37.2±10.0 µm and 152.7±10.9 µm, respectively, and at high-flow by 62.3±5.6 µm and 163.4±25.4 µm, respectively (p<0.001). Mucus velocity was increased by both 0.9% and 7.0% saline from a baseline of 8.2±0.8 mm·min-1 to 8.8±0.7 mm·min-1 and 17.1±0.5 mm·min-1, respectively, with low-flow and at high-flow to 9.8±0.02 mm·min-1 (p=0.04) and 16.9±0.5 mm·min-1 (p<0.05), respectively. Ciliary beating did not change with 0.9% saline, but declined from 13.1±0.6 Hz to 10.2±0.6 Hz and 11.1±0.6 Hz (p<0.05) with 7.0% saline at low- and high-flow, respectively. CONCLUSIONS: The findings demonstrate that nebulised isotonic 0.9% saline, like hypertonic 7.0% saline, significantly stimulates basal mucociliary transport, and the use of high-flow delivery had no significantly different hydration effects compared with low-flow delivery. Hypertonic 7.0% saline suppressed ciliary beating, indicating an increase in airway surface liquid osmolarity, which may have negative effects on the airway surface with frequent use.
