Cardiogenic Shock Prior to Percutaneous Coronary Intervention in ST-Elevation Myocardial Infarction: Outcomes and Predictors of Mortality (ANZACS-QI 73).

BACKGROUND & AIMS: Cardiogenic shock (CS) is a serious complication of acute myocardial infarction (MI) and is associated with significant mortality. We describe a contemporary, real-world cohort of patients with ST-elevation MI (STEMI) and CS, including 30-day mortality and clinically relevant predictors of mortality. METHODS: All patients presenting with STEMI who were treated with percutaneous coronary intervention (PCI) in New Zealand (2016 to 2020) were identified from the Aotearoa New Zealand All Cardiology Services Quality Improvement (ANZACS-QI) registry and stratified based on their Killip class on arrival to the cardiac catheterisation laboratory. Primary outcome was 30-day all-cause mortality. Multivariable analysis was used to identify predictors of mortality prior to PCI and to develop a mortality scoring system. RESULTS: In total, 6,649 patients were identified, including 192 (2.9%) Killip IV (CS) patients. Thirty-day mortality was 47.5% in patients with CS, 14.6% in those with heart failure without shock, and 3% in those without heart failure. Independent predictors of 30-day mortality for patients with CS were: estimated glomerular filtration rate <60 mL/min/1.73m2 (relative risk [RR] 1.89, 95% confidence interval [CI] 1.39-2.58), cardiac arrest (RR 1.54, 95% CI 1.15-2.06), diabetes (RR 1.31, 95% CI 1.01-1.70), female sex (RR 1.32, 95% CI 1.01-1.72), femoral arterial access (RR 1.42, 95% CI 1.06-1.90) and left main stem culprit (RR 2.16, 95% CI 1.65-2.84). A multivariable Shock score was developed which predicts 30-day mortality with good global discrimination (area under the curve 0.79, 95% CI 0.73-0.85). CONCLUSION: In this national cohort, the 30-day mortality for STEMI patients presenting with CS treated with PCI remains high, at nearly 50%. The ANZACS-QI Shock score is a promising tool for mortality risk stratification prior to PCI but requires further validation.

The lived experience of chronic pain for Maori: how can this inform service delivery and clinical practice? A systematic review and qualitative synthesis.

AIM: To synthesise the literature describing experiences of chronic pain and pain management for Maori, and to understand how this experience could inform service delivery and clinical practice. METHOD: We systematically searched for qualitative research on Maori chronic pain experiences (Scopus, Medline, APA PsycINFO, NZ Research, Research Square). Data extracted were coded and synthesised using thematic analysis. RESULTS: Seven studies were included. Three themes encapsulated the data: 1) a multidimensional view of pain and pain management: Maori expressed a holistic and integrated understanding of the multiple factors that influence pain and its management, 2) a responsibility: respectful tikanga-informed care: the experiences of Maori participants with healthcare highlight a need for antiracist approaches, and a clinical responsibility to practice manaakitanga and tikanga, and 3) tino rangatiratanga: a desire for knowledge, choice and autonomy in pain management: Maori valued the empowering nature of knowledge about pain, and information and support to make decisions about treatment, including considerations regarding Western and traditional Maori medicine. CONCLUSION: Health services need to understand and respect the multidimensional aspects of pain, minimise racism and discrimination, use whakawhanaungatanga, manaakitanga, and tikanga-informed practices, and provide appropriate information to support tino rangatiratanga for pain management.

Prevalence of Micronutrient Deficiencies in Preoperative Bariatric Patients in a New Zealand Tertiary Centre.

PURPOSE: A potential complication of bariatric surgery is development of nutritional deficiencies. Study aims were to assess prevalence of micronutrient deficiencies in preoperative bariatric patients and to examine for ethnic differences. METHODS: Retrospective analysis of 573 patients that underwent bariatric surgery at Counties Manukau District Health Board was carried out. Mean preoperative levels of albumin, calcium, phosphate, folate, vitamin B12, vitamin D, magnesium, haemoglobin, haematocrit, mean cell volume, mean cell haemoglobin, ferritin, iron, and transferrin were calculated. Chi square, fisher exact test, and multiple logistic regression was used to assess for differences in prevalence of micronutrient deficiencies across ethnicities. RESULTS: The most common micronutrient deficiency was vitamin D (30.85%). There were statistically significant differences in vitamin D deficiency across ethnicities (p < 0.0001). Asians had the highest prevalence of vitamin D deficiency (60%), followed by Pacifica (44.57%), and Maori (31.68%). Asians were more likely to have vitamin D deficiency compared to NZ/Other Europeans (OR = 14.93, p < 0.001). Vitamin D deficiency was associated with higher BMI (OR = 1.05, p = 0.008). The second most common deficiency was iron (21.1%). Asians had the highest prevalence of iron deficiency (44%), followed by Maori (27.95%), and Pacifica (19.57%) (p = 0.0064). Compared to NZ/Other Europeans, Asians (OR = 4.26) and Maori (OR = 1.78) were more likely to be iron deficient (p = 0.004). Female gender was associated with iron deficiency (OR = 2.12, p = 0.007). CONCLUSION: Vitamin D and iron are the most common micronutrient deficiencies among preoperative bariatric patients in this cohort and ethnic differences were seen. There may be a role for preoperative supplementation in these at-risk ethnic groups.

Contribution of Infant Food Pouches and Other Commercial Infant Foods to the Diets of Infants: A Cross-sectional Study.

BACKGROUND: Although considerable concern has been expressed about the nutritional implications of infant food pouches, how they impact infant diet has not been examined. OBJECTIVES: The objective of this study was to determine the contribution of infant food pouches specifically, and commercial infant foods generally, to nutrient intake from complementary foods in infants. METHODS: Two multiple-pass 24-h diet recall data were collected from 645 infants (6.0-11.9 mo) in the First Foods and Young Foods New Zealand studies. Detailed information was obtained on commercial infant food use, including pouches, and nutrient composition was calculated through recipe modeling. RESULTS: The diverse sample (46.1% female; 21.1% Maori, 14.1% Asian, and 54.6% European) was aged (SD) 8.4 (0.9) mo. More than one-quarter of households had high socioeconomic deprivation. Almost half (45.3%) of infants consumed an infant food pouch on ≥1 recall day [mean (SD), 1.3 (0.9) times/d], obtaining 218 (124) kJ of energy on each eating occasion. Comparable numbers for all commercial infant and toddler foods (CITFs) were 78.0%, contributing 2.2 (1.6) and 140 (118) kJ of energy. Infant food pouches provided 25.5% of the total energy from complementary foods in those infants who consumed pouches on the recall days but just 11% in all infants. Median percentage contribution of infant food pouches to nutrient intake from complementary foods in consumers ranged from <1% (added sugars and retinol) to >30% (carbohydrate, total sugars, fiber, vitamin A, and vitamin C). CITF contributed 21.4% of energy from complementary foods for infant consumers, with median percentage contribution ranging from 0.1% (retinol) to 40.3% (iron). CONCLUSIONS: Infant food pouches make relatively small contributions to energy intake in infants but are important sources of carbohydrates, fiber, and vitamins A, C, and B-6. Almost half of the total sugars consumed from complementary foods is provided by these pouches. This trial was registered at the Australian New Zealand Clinical Trials Registry as ACTRN12620000459921.

A scoping review of Indigenous community-specific physical activity measures developed with and for Indigenous Peoples in Canada, Australia, and New Zealand.

Historical factors including colonization and ongoing socioeconomic inequities impact Indigenous Peoples' ability to mitigate chronic disease risks such as achieving recommended physical activity (PA) levels. Reliably assessing, reflecting, and promoting PA participation among Indigenous Peoples may be impacted by a lack of culturally appropriate assessment methods and meaningful engagement with Indigenous communities throughout the research process. The objectives of this scoping review were to examine: (1) How PA research with Indigenous Peoples used community-specific PA measures developed with and/or for Indigenous Peoples in Canada, Australia, and New Zealand; and (2) How the studies utilized community-based participatory research (CBPR) principles to engage communities. A systematic search was conducted in four electronic databases (Web of Science, Medline, University of Saskatchewan Indigenous Portal, and ProQuest Dissertations and Theses Global). Thirty-one (n = 31) articles were identified and data extracted for narrative synthesis. Studies using community-specific PA measures have been increasing over time. Adapting questionnaires to traditional Indigenous activities such as cultural dances, ceremonies, and food-gathering activities were the most frequent adjustments undertaken to use community-specific measures. There are, however, gaps in research partnering with communities with only 6% of studies including all eight CBPR principles. Practical ways researchers can engage Indigenous communities and build capacity such as training and employing community members were highlighted. More needs to be done to facilitate community self-determination and develop long-term sustainable initiatives. Using culturally appropriate and relevant methodologies including partnering with Indigenous communities may help identification and implementation of culturally relevant and sustainable health-promoting initiatives.

He Taonga Te Wareware: Connecting Older Maori Experiences of Wairuatanga with Mate Wareware (Dementia).

Mate wareware (dementia) is a complex disease of the brain that progressively inhibits memory and cognitive ability, affecting many Maori (the Indigenous people of Aotearoa New Zealand) kaumatua (elderly persons) in Aotearoa (New Zealand). Mate wareware care aims to protect and sustain wellbeing, yet Maori perspectives of wellbeing that consider wairuatanga (Maori spirituality) are often neglected within current treatment planning. This study investigates the presence of wairuatanga within kaumatua lives, drawing upon 61 interviews with kaumatua to glean a Maori understanding of mate wareware and to develop a diagnostic screening tool for mate wareware. Recorded responses were thematically analysed using reflexive qualitative analysis, informing four key themes that influence wairuatanga: he hononga tangata (social connection), turangawaewae (places of connection), tuakiritanga (identity) and mahi mauritau (mindful practices). These themes consider the value of creating rich and gratifying lifestyles for kaumatua that cultivate their spiritual wellbeing. This study validates diverse understandings and experiences of wairuatanga as essential to Maori wellbeing, affirming the relevance of wairuatanga to improve outcomes for Maori living with mate wareware.

Key elements and contextual factors that influence successful implementation of large-system transformation initiatives in the New Zealand health system: a realist evaluation.

BACKGROUND: Despite three decades of policy initiatives to improve integration of health care, delivery of health care in New Zealand remains fragmented, and health inequities persist for Maori and other high priority populations. An evidence base is needed to increase the chances of success with implementation of large-system transformation (LST) initiatives in a complex adaptive system. METHODS: This research aimed to identify key elements that support implementation of LST initiatives, and to investigate contextual factors that influence these initiatives. The realist logic of enquiry, nested within the macro framing of complex adaptive systems, formed the overall methodology for this research and involved five phases: theory gleaning from a local LST initiative, literature review, interviews, workshop, and online survey. NVivo software programme was used for thematic analysis of the interview, workshop, and the survey data. We identified key elements and explained variations in success (outcomes) by identifying mechanisms triggered by various contexts in which LST initiatives are implemented. RESULTS: The research found that a set of 10 key elements need to be present in the New Zealand health system to increase chances of success with implementation of LST initiatives. These are: (i) an alliancing way of working; (ii) a commitment to te Tiriti o Waitangi; (iii) an understanding of equity; (iv) clinical leadership and involvement; (v) involved people, whanau, and community; (vi) intelligent commissioning; (vii) continuous improvement; (viii) integrated health information; (ix) analytic capability; and (x) dedicated resources and time. The research identified five contextual factors that influenced implementation of LST initiatives: a history of working together, distributed leadership from funders, the maturity of Alliances, capacity and capability for improvement, and a continuous improvement culture. The research found that the key mechanism of trust is built and nurtured over time through sharing of power by senior health leaders by practising distributed leadership, which then creates a positive history of working together and increases the maturity of Alliances. DISCUSSION: Two authors (KMS and PBJ) led the development and implementation of the local LST initiative. This prior knowledge and experience provided a unique perspective to the research but also created a conflict of interest and introduced potential bias, these were managed through a wide range of data collection methods and informed consent from participants. The evidence-base for successful implementation of LST initiatives produced in this research contains knowledge and experience of senior system leaders who are often in charge of leading these initiatives. This evidence base enables decision makers to make sense of complex processes involved in the successful implementation of LST initiatives. CONCLUSIONS: Use of informal trust-based networks provided a critical platform for successful implementation of LST initiatives in the New Zealand health system. Maturity of these networks relies on building and sustaining high-trust relationships among the network members. The role of local and central agencies and the government is to provide the policy settings and conditions in which trust-based networks can flourish.

Statement of the Rehabilitation Medicine Society of Australia and New Zealand for the therapeutic use of botulinum toxin A in spasticity management.

The Rehabilitation Medicine Society of Australia and New Zealand advocates the safe, effective and evidence-based use of botulinum toxin type A for spasticity management. The process requires appropriate training, alongside considerable knowledge and skills, to maximise efficacy. The processes before and after injection contribute to effectiveness. The gold standard of managing spasticity is for assessment by a multidisciplinary specialist team, deriving patient-centric goals, and designing an injection protocol to match these goals. The patient and/or carers are considered part of the decision-making team. Postinjection therapy and measurement of goal achievement are highly recommended as part of the wider holistic approach to management. The Society believes treatment failures can be minimised by following clear clinical guidelines.

Tuakana-teina peer education programme to help Maori elders enhance wellbeing and social connectedness.

BACKGROUND: There are significant inequities between Maori (Indigenous people) and non-Maori in ageing outcomes. This study used a strengths-based approach based on the key cultural concept of mana motuhake (autonomy and self-actualisation) to develop a tuakana-teina (literally older sibling-younger sibling) peer education programme to assist kaumatua (elders) in addressing health and social needs. The purpose of this study was to test the impact on those receiving the programme. Three aims identify the impact on outcomes, resources received and the cost effectiveness of the programme. METHODS: Five Kaupapa Maori (research and services guided by Maori worldviews) iwi (tribe) and community providers implemented the project using a partnership approach. Tuakana (peer educators) had up to six conversations each with up to six teina (peer learners) and shared information related to social and health services. A pre- and post-test, clustered staggered design was the research design. Participants completed a baseline and post-programme assessment of health and mana motuhake measures consistent with Maori worldviews. Open-ended questions on the assessments, five focus groups, and four individual interviews were used for qualitative evaluation. FINDINGS: A total of 113 kaumatua were recruited, and 86 completed the programme. The analysis revealed improvements in health-related quality of life, needing more help with daily tasks, life satisfaction, paying bills and housing problems. Qualitative results supported impacts of the programme on mana motuhake and hauora (holistic health) through providing intangible and tangible resources. Cost-effectiveness analysis showed that the intervention is cost effective, with a cost per QALY of less than the conventional threshold of three times GDP per capita. CONCLUSIONS: A culturally-resonant, strengths-based programme developed through a participatory approach can significantly improve health and social outcomes in a cost-effective way.

Manuka oil based ECMT-154 versus vehicle control for the topical treatment of eczema: study protocol for a randomised controlled trial in community pharmacies in Aotearoa New Zealand.

BACKGROUND: Eczema is a chronic, relapsing skin condition commonly managed by emollients and topical corticosteroids. Prevalence of use and demand for effective botanical therapies for eczema is high worldwide, however, clinical evidence of benefit is limited for many currently available botanical treatment options. Robustly-designed and adequately powered randomised controlled trials (RCTs) are essential to determine evidence of clinical benefit. This protocol describes an RCT that aims to investigate whether a manuka oil based emollient cream, containing 2% ECMT-154, is a safe and effective topical treatment for moderate to severe eczema. METHODS: This multicentre, single-blind, parallel-group, randomised controlled trial aims to recruit 118 participants from community pharmacies in Aotearoa New Zealand. Participants will be randomised 1:1 to receive topical cream with 2% ECMT-154 or vehicle control, and will apply assigned treatment twice daily to affected areas for six weeks. The primary outcome is improvement in subjective symptoms, assessed by change in POEM score. Secondary outcomes include change in objective symptoms assessed by SCORAD (part B), PO-SCORAD, DLQI, and treatment acceptability assessed by TSQM II and NRS. DISCUSSION: Recruitment through community pharmacies commenced in January 2022 and follow up will be completed by mid-2023. This study aims to collect acceptability and efficacy data of manuka oil based ECMT-154 for the treatment of eczema. If efficacy is demonstrated, this topical may provide an option for a novel emollient treatment. The community-based design of the trial is anticipated to provide a generalisable result. ETHICS AND DISSEMINATION: Ethics approval was obtained from Central Health and Disability Ethics Committee (reference: 2021 EXP 11490). Findings of the study will be disseminated to study participants, published in peer-reviewed journal and presented at scientific conferences.

How do people who smoke perceive a tobacco retail outlet reduction policy in Aotearoa New Zealand? A qualitative analysis.

BACKGROUND: Aotearoa New Zealand plans to greatly reduce tobacco retail outlets, which are concentrated in areas of higher deprivation and perpetuate health inequities caused by smoking and borne particularly by Maori. However, we lack in-depth analyses of how this measure could affect people who smoke. METHODS: We undertook in-depth interviews with 24 adults from two urban areas who smoke. We used a novel interactive mapping approach to examine participants' current retail outlets and their views on a scenario where very few outlets would sell tobacco. To inform policy implementation, we probed participants' anticipated responses and explored the measure's wider implications, including unintended impacts. We used qualitative description to interpret the data. RESULTS: Most participants anticipated accommodating the changes easily, by using alternative outlets or bulk-purchasing tobacco; however, they felt others would face access problems and increased costs, and greater stress. They thought the policy would spur quit attempts, reduce relapse among people who had quit and protect young people from smoking uptake, and expected more people to switch to alternative nicotine products. However, most foresaw unintended social outcomes, such as increased crime and reduced viability of local businesses. CONCLUSIONS: Many participants hoped to become smoke-free and thought retail reduction measures would prompt quit attempts and reduce relapse. Adopting a holistic well-being perspective, such as those developed by Maori, could address concerns about unintended adverse outcomes and provide comprehensive support to people who smoke as they adjust to a fundamental change in tobacco availability.

A quality improvement approach to improving recognition of Maori tamariki (children) and assessing barriers to culturally responsive care in a paediatric ward setting.

BACKGROUND: Health inequity persists in Aotearoa (New Zealand) and internationally amongst most indigenous peoples. To address these health inequities, countries need to contend with the ramifications of entrenched historical, cultural and systemic failures. Within Aotearoa part of the solution to rectifying persistent health inequities lies in shifting everyday healthcare practices towards a more culturally responsive, patient-centred approach that utilises Maori knowledge and principles. Although the need for culturally responsive services in healthcare settings is clearly evident, most practitioners struggle with the challenge of creating a culturally safe environment. Further to these challenges, there are issues related to accurate recognition of ethnicity within the time constraints of an overwrought hospital environment. Within this environment, the correct identification of ethnicity is a fundamental step in the process of moving towards culturally responsive and more inclusive care. METHOD: The research was concerned with indigenous Maori patients being consistently and correctly identified so that they might receive culturally appropriate interaction and treatment. The research specifically focused on the impact of introducing a customised sticker prompt on the front cover of clinical notes of Maori tamariki (children) to assist with correct ethnicity identification. Surveys were conducted on the paediatric ward over a 3-week period, prior to and during the intervention to evaluate the effect of the customised stickers. This study sought to (1) assess the efficacy of a sticker to improve recognition of Maori tamariki (children), (2) examine key barriers to identifying ethnicity and (3) identify wider impacts of a sticker prompt on clinical practice. RESULTS: Results showed wide ranging positive impacts on clinical practice and culturally responsive care. Sixty-four per cent of participants indicated that the stickers were a useful tool to improve identification of Maori tamariki. Respondents reported increased accuracy of identifying patients by ethnicity, as well as improved awareness of existing ethnicity documentation, and increased engagement regarding cultural needs and ethnicity. CONCLUSIONS: This study identified that sticker prompts are a useful tool for healthcare workers to improve recognition and awareness of ethnicity and to increase dialogue around cultural needs. The stickers led to increased consideration of the wider elements of holistic wellbeing and therefore improved culturally responsive care for Maori tamariki.

Whakawhanaungatanga-Building trust and connections: A qualitative study indigenous Maori patients and whanau (extended family network) hospital experiences.

AIMS: Investigated the experiences of Maori (the Indigenous peoples of Aotearoa, New Zealand) patients and whanau (extended family network) engaging with acute hospital inpatient services and their priorities for a Maori-centred model of relational care. DESIGN: A qualitative Maori-centred research design using a Thought Space Wananga (learning through in-depth group discussion, deliberation and consideration) approach. METHODS: Two wananga were conducted between May 2022 and June 2022, with 13 Maori patients who had been acutely hospitalized within the past 12 months and their whanau members. The first wananga utilized storytelling and journey mapping to collect data. The second wananga refined the initial themes. Wananga were audio-recorded and then inductively coded and developed into themes. RESULTS: Thirteen patients and whanau attended the first wananga, while 10 patients and whanau participated in the second wananga). Four themes were developed: (1) Whakawhanaungatanga (establishing connections and relationships), (2) Whakamana (uplifting the status and esteem of Maori), (3) Whakawhitiwhiti korero (the importance of communicating, discussing and deliberating) and (4) Kotahitanga (working together with purpose) all provide insights into the importance of effectively engaging and connecting with Maori patients and whanau when acutely hospitalized. CONCLUSIONS: The experiences and priorities of Maori patients and whanau affirm the international literature, suggesting that Indigenous relational concepts are critical to building relationships, connections and trust. Despite existing healthcare models for working with Indigenous peoples, their poor application contributes to sub-optimal healthcare experiences at all points of their healthcare journey. A relational mode of practice focused on engagement and forming connections better meets the needs of Indigenous peoples engaging with inpatient health services. IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: Despite the existence of Indigenous models of care, Indigenous peoples consistently report a lack of engagement and connection when accessing inpatient health services. Without establishing relationships, applying models of care is challenging. IMPACT (ADDRESSING): What problem did the study address? Internationally, healthcare systems are consistently ill-equipped to deliver culturally safe care for Indigenous and marginalized peoples, evident in ongoing health inequities. Like other reports of Indigenous experiences of health services, Maori express dissatisfaction with care delivery in an acute inpatient setting. This study investigated Maori patients and whanau experiences engaging with acute hospital inpatient services and their priorities for a Maori-centred model of relational care. What were the main findings? Maori patients and whanau recounted negative experiences with healthcare professionals lacking effective relationships and trust. Satisfaction occurred when engagement with health care professionals resembled Indigenous cultural rituals of encounter that considered their holistic, collective and dynamic worldviews. Previous models of relational care, while helpful, are not Indigenous and so do not address their needs, such as engagement as a mode of practice (how) to achieve this. Where and on whom will the research have an impact? This research impacts Indigenous peoples' health outcomes, particularly Maori, and nurses and clinicians working and interacting within acute inpatient and other hospital settings. Indigenous research methods support co-constructing knowledge for translation into practical outcomes through transformational practices, policies and theory development. REPORTING METHOD: We used the Consolidated Criteria for Strengthening the Reporting of Health Research Involving Indigenous Peoples (CONSIDER) statement (see File S2-CONSIDER Checklist) and the Consolidated Criteria for Reporting Qualitative Research (COREQ) guidelines (see File S3-COREQ Checklist). PATIENT OR PUBLIC CONTRIBUTION: Maori patients and their whanau interviewed about their experiences were involved in data interpretation.

The effect of parenteral vitamin B12 on the growth rate of dairy calves over the summer and autumn on seven farms from the Central Plateau, New Zealand.

AIMS: To investigate the effect of parenteral vitamin B12 supplementation on the growth rate of dairy heifer calves over the summer and autumn on seven farms from the Central Plateau of New Zealand, an area historically associated with low cobalt levels in grazing pasture. METHODS: This was a controlled clinical trial conducted on a convenience sample of seven farms with young female calves randomly assigned to three vitamin B12 treatment groups and followed through a grazing season. Two treatment groups received either monthly SC injections of a short-acting (SA) B12 formulation or 3-monthly injections of a long-acting (LA) B12 formulation and the third group received no treatment (NT). No additional parenteral vitamin B12 was given; however, all calves received additional cobalt (0.04-0.4 mg Co/kg liveweight) in the mineralised anthelmintic drenches given orally every month. Liveweight was recorded in December/January and at the end of the trial in May/June/July depending on farm. Pasture cobalt concentrations (mg/kg DM) were measured every month using 500-g herbage samples from 100-m transects in the area about to be grazed by the trial groups. RESULTS: There was evidence for a difference in growth rate between groups with mean final weight of 228 (95% CI = 212-243) kg for the LA groups, 224 (95% CI = 209-239) kg for the SA groups and 226 (95% CI = 211-241) kg for the NT groups respectively, (global p-value = 0.014). Calves given SA vitamin B12 were 3.77 (95% CI = 0.71-6.82) kg lighter than calves given LA vitamin B12 (p = 0.011). There was no evidence for a change in pasture cobalt concentrations (p = 0.32). CONCLUSIONS AND CLINICAL RELEVANCE: The results of this trial raise the question as to whether the routine use of vitamin B12 supplementation in young cattle from areas traditionally thought to be cobalt deficient is necessary, and further raise the possibility that vitamin B12 supplementation by repeated injection of SA products may negatively impact growth rates.

Changes in serum and faecal zinc concentrations following supplementation with zinc sulphate heptahydrate of extensively grazed dairy cattle in New Zealand.

AIMS: To examine the relationship in dairy cattle between serum and faecal Zn concentrations and daily intake of Zn supplemented with an oral drench; and whether total daily intake (TDI) of Zn in dairy cattle can be predicted from single measurements of Zn concentration in serum or faeces. METHODS: A convenience sample of 20 animals from three stock classes (lactating cows, dry cows, heifers), that had not received Zn supplementation in the previous 60 days, was enrolled in the study. From Days -7 to -1, animals received no Zn supplementation. On Day 0, 15 animals per class were assigned daily drenching with increasing doses of ZnSO4.7H2O while five remained controls. From Days 0-6, treatment animals received 12.5 mg/kg LWT of Zn/day; from Days 7-13, 25 mg/kg LWT Zn/day and from Days 14-20, 37.5 mg/kg LWT Zn/day. Animals co-grazed within each stock class. Pasture, serum and faecal samples were collected at the start and at weekly intervals before each increase in Zn supplementation. Mixed and non-parametric models were used to assess treatment effects and whether daily intake of Zn could be predicted from Zn concentrations in serum and faeces. RESULTS: Dosing with 0, 12.5, 25.0 and 37.5 mg Zn/kg LWT resulted in serum Zn concentrations of 12.1, 16.7, 27.2 and 35.8 µmol/L in heifers, 13.3, 17.1, 26.4 and 40.0 µmol/L in dry and 11.9, 12.1, 23.4 and 27.2 µmol/L in lactating cows. Dosing with the same amounts of Zn resulted in faecal Zn concentrations of 2.95, 21.72, 40.32 and 53.27 mmol/kg DM in heifers, 2.81, 23.77, 55.16 and 68.20 mmol/kg DM in dry and 3.00, 12.71, 34.86 and 57.53 mmol/kg DM in lactating cows, respectively. Treatment elevated serum and faecal Zn concentrations above controls (p < 0.001). Supplemented lactating cows had lower serum Zn concentrations than dry cows or heifers (p < 0.01). Supplemented dry cows had faecal DM Zn concentrations higher than heifers or lactating cows (p < 0.05). Analysis showed serum and faecal Zn concentrations could predict TDI of Zn (p < 0.001). Concentrations of Zn in faeces estimated TDI of Zn within a narrower predictive interval than serum Zn concentrations. CONCLUSIONS AND CLINICAL RELEVANCE: Concentrations of Zn in serum and faeces were positively associated with TDI of Zn in dairy cattle and could predict TDI of Zn. When using serum and faecal Zn concentrations to estimate TDI Zn, stock class must be accounted for.

Holistic health for Pacific seniors from a weekly group gathering run by a Pacific health provider.

Introduction Manatu Hauora (Aotearoa New Zealand (NZ) Ministry of Health) recognises that respecting and listening to Pacific peoples' knowledge and skills in caring for their communities' wellbeing is a priority, and that novel approaches to care, particularly for chronic health conditions, are necessary. Allied health professionals have the potential to play important roles in primary care design and delivery. Pacific Trust Otago (PTO) provides a weekly seniors' group gathering that has evolved over the years and incorporates exercise, health information and cultural activities. Aim This study aims to explore what Pacific seniors are learning about their health and wellbeing, and what factors contribute to sustained engagement with this weekly group activity. Methods The research team conducted a qualitative study using the Kakala Research Framework and the pan-Pacific Talanoa Research Methodology to gather narratives in a relational and comfortable group space. Participants were recruited from the seniors group gathering. Group Talanoa were used to collect data, which were digitally voice-recorded, transcribed, translated, and de-identified. Ethical approval was granted by the University of Otago School of Physiotherapy Ethics Committee. Results Pacific seniors valued how these gathering The seniors recognised how interconnected and intertwined culture, spirituality, and family were and how this contributed to their sense of individual and collective health and wellbeing. The study highlights the need to consider health beyond the individual to the collective, embracing indigenous perspectives, and authentically nurturing relationships with Pacific health providers. The study recommends primary care funders are supported to understand what is important to Pacific people and partner with Pacific health providers to deliver care in ways that align with indigenous models of care. Discussion A weekly group gathering for Pacific seniors run by Allied Health professionals provides a welcoming, safe, and culturally meaningful environment where seniors can connect, share, and grow in health and wellbeing together. This study highlights the importance of adopting informed and inclusive approaches to promoting and addressing holistic health for Pacific people, especially in light of ongoing health reforms in Aotearoa NZ.

Micronutrient status of New Zealand adolescent women consuming vegetarian and non-vegetarian diets.

BACKGROUND AND OBJECTIVES: Globally, there appears to be an ever-increasing interest in adopting a vegetarian diet. However, there are concerns that avoiding meat may increase the risk of anaemia and micronutrient deficiencies, especially for vulnerable populations, such as adolescent women. The objective of this study was to compare the micronutrient status of vegetarian and non-vegetarian adolescent women in New Zealand. METHODS AND STUDY DESIGN: Adolescent women aged 15-18 y were recruited from eight locations across New Zealand. Blood samples were analysed for: haemoglobin, serum ferritin, soluble transferrin receptor, zinc, selenium, retinol binding protein, folate, vitamin B-12, vitamin D and parathyroid hormone. RESULTS: Of the 182 participants who provided a blood sample, 15% self-identified as vegetarian (n=27). On average, vegetarians had 3.1% (95% CI -5.8 to -0.4, p=0.025) lower haemoglobin, and 8.3% (95%CI -14.1 to -2.1, p=0.004) lower selenium. In contrast, serum folate was 80.5% (95% CI 45.7 to 123.7, p<0.001) higher. The prevalence of zinc and selenium deficiency was higher among vegetarians (50% and 12%, respectively) than non-vegetarians (21%, and 2%, respectively). CONCLUSIONS: Adolescent vegetarian women may be at increased risk of deficiency of micronutrients commonly found in animal products, including zinc and selenium, and may benefit from following dietary practices that enhance micronutrient intake and absorption.

Investigation and treatment after non-ST segment elevation acute coronary syndrome for patients presenting to rural or urban hospitals in Aotearoa New Zealand: ANZACS-QI 75.

AIMS: Compare the care patients with non-ST segment elevation acute coronary syndrome (NSTEACS) received in Aotearoa New Zealand depending on the rural-urban category of the hospital they are first admitted to. METHODS: Patients with NSTEACS investigated with invasive coronary angiogram between 1 January 2014 and 31 December 2019 were included. There were three hospital categories (routine access to percutaneous coronary intervention [urban interventional], other urban [urban non-interventional] and rural) and three ethnicity categories (Maori, Pacific and non-Maori/non-Pacific). Clinical performance measures included: angiography ≤3 days, assessment of left ventricular ejection fraction (LVEF) and prescription of secondary prevention medication. RESULTS: Of 26,779 patients, 66.2% presented to urban-interventional, 25.6% to urban non-interventional and 8.2% to rural hospitals. A smaller percentage of patients presenting to urban interventional than urban non-interventional and rural hospitals were Maori (8.1%, 17.0% and 13.0%). Patients presenting to urban interventional hospitals were more likely to receive timely angiography than urban non-interventional or rural hospitals (78.5%, 60.8% and 63.1%). They were also more likely to have a LVEF assessment (78.5%, 65.4% and 66.3%). In contrast, the use of secondary prevention medications at discharge was similar between hospital categories. Maori and Pacific patients presenting to urban interventional hospitals were less likely than non-Maori/non-Pacific to receive timely angiography but more likely to have LVEF assessed. However, LVEF assessment and timely angiography in urban non-interventional and rural hospitals were lower than in urban interventional hospitals for both Maori and non-Maori/non-Pacific. CONCLUSIONS: Patients presenting to urban hospitals without routine interventional access and rural hospitals were less likely to receive LVEF assessment or timely angiography. This disproportionately impacts Maori, who are more likely to live in these hospital catchments.

Adherence to Infant Feeding Guidelines in the First Foods New Zealand Study.

Infant feeding guidelines provide evidence-based recommendations to support optimal infant health, growth, and development, and exploring adherence to guidelines is a useful way of assessing diet quality. The aim of this study was to determine adherence to the recently updated Ministry of Health "Healthy Eating Guidelines for New Zealand Babies and Toddlers (0-2 years old)". Data were obtained from First Foods New Zealand, a multicentre observational study of 625 infants aged 7.0-10.0 months. Caregivers completed two 24-h diet recalls and a demographic and feeding questionnaire. Nearly all caregivers (97.9%) initiated breastfeeding, 37.8% exclusively breastfed to around six months of age, and 66.2% were currently breastfeeding (mean age 8.4 months). Most caregivers met recommendations for solid food introduction, including appropriate age (75.4%), iron-rich foods (88.3%), puréed textures (80.3%), and spoon-feeding (74.1%). Infants consumed vegetables (63.2%) and fruit (53.9%) more frequently than grain foods (49.5%), milk and milk products (38.6%), and meat and protein-rich foods (31.8%). Most caregivers avoided inappropriate beverages (93.9%) and adding salt (76.5%) and sugar (90.6%). Our findings indicated that while most infants met the recommendations for the introduction of appropriate solid foods, the prevalence of exclusive breastfeeding could be improved, indicating that New Zealand families may need more support.

Death after endoscopic prostate surgery in Australia and New Zealand: a review of clinical management issues.

BACKGROUND: Endoscopic prostate surgery is an established treatment for male lower urinary tract symptoms (LUTS) and is recognized to have low mortality rates. We aimed to describe factors that may have contributed to death following endoscopic prostate surgery using data from the Australia and New Zealand Audits of Surgical Mortality (ANZASM). METHODS: All urological related deaths reported to ANZASM from January 1 2012 to December 31 2019 were reviewed. Deaths related to endoscopic prostate resection (transurethral resection of prostate - TURP, laser procedures) were included. Peer reviewers identified up to three clinical management issues (CMIs), and these were analysed. CMIs were classified in order of least to most concerning: area of consideration, area of concern and adverse events. RESULTS: Of 1127 total urological deaths, 77 deaths were related to endoscopic prostate surgery (7.0%). Most procedures were monopolar TURP. The mean age of patients was 80.9 years (range 57.0-96.2). Leading causes of death were cardiovascular events 23/77 (29.9%) and respiratory failure 14/77 (18.2%). Assessors identified 39 CMIs in 26/77 (33.8%) patients. Twenty-three were areas of consideration, nine were areas of concern and seven identified adverse events. The most common CMIs were regarding post-operative care (14/39) and the decision to operate (13/39). CONCLUSION: Most deaths did not elicit concerns from the ANZASM peer assessors. However, the main concerns identified were surrounding decision making and rationale for operating. This highlights the importance of clear counselling and documentation during the treatment decision process.
