Introduction Recent estimations have projected a threefold increase in dementia prevalence in Aotearoa New Zealand (NZ) by 2050, particularly in Maori and Pacific peoples. However, to date, there are no national data on dementia prevalence, and overseas data are used to estimate the NZ dementia statistics. The aim of this feasibility study was to prepare the groundwork for the first full-scale NZ dementia prevalence study that is representative of Māori, European, Pacific and Asian peoples living in NZ. Methods The main feasibility issues were: (i) Sampling to ensure adequate community representation from the included ethnic groups, (ii) Preparing a workforce to conduct the fieldwork and developing quality control, (iii) Raising awareness of the study in the communities (iv) Maximizing recruitment by door-knocking, (v) Retaining those we have recruited to the study and (vi) Acceptability of study recruitment and assessment using adapted versions of the 10/66 dementia protocol in different ethnic groups living in South Auckland. Results We found that a probability sampling strategy using NZ Census data was reasonably accurate and all ethnic groups were sampled effectively. We demonstrated that we were able to train up a multi-ethnic workforce consisting of lay interviewers who were able to administer the 10/66 dementia protocol in community settings. The response rate (224/297, 75.5%) at the door-knocking stage was good but attrition at subsequent stages was high and only 75/297 (25.2%) received the full interview. Conclusions Our study showed that it would be feasible to conduct a population-based dementia prevalence study using the 10/66 dementia protocol in Māori, European and Asian communities living in NZ, utilizing a qualified, skilled research team representative of the families participating in the study. The study has demonstrated that for recruitment and interviewing in Pacific communities a different but culturally appropriate approach is required.

Dementia is an important health concern for Māori and therefore it is essential to explore the extent and impact of dementia in this community. The 10/66 dementia protocol, a widely used research tool for measuring the prevalence of dementia, was developed to minimise cultural and educational bias in comparisons of dementia prevalence across different countries and/or cultures. The aims of this study are to (i) adapt the 10/66 dementia protocol for use in research within the Māori community and (ii) test the diagnostic accuracy of the adapted (ie, Māori-friendly) 10/66 dementia protocol against the reference standard of a clinical diagnosis of dementia (or no dementia).The sample included Māori aged 65 and over who had been assessed at a local memory service. Ten dementia cases and 10 controls were included. The sample was further enriched by the inclusion of 6 controls from a concurrent dementia-prevalence feasibility study in the local community. The Māori-friendly 10/66 dementia protocol was measured against the reference standard. Sensitivity, specificity, positive and negative predictive values and Youden's Index were calculated.The Māori-friendly 10/66 dementia protocol had a sensitivity of 90.0% (95% CI 62.8-99.4), specificity of 93.8% (95% CI 75.3-99.6), positive predictive value of 90.0% (95% CI 62.8-99.4), negative predictive value of 93.8% (95% CI 75.3-99.6) and Youden's Index of 0.83.Our study results provide preliminary evidence that the Māori-friendly 10/66 dementia protocol has adequate discriminatory abilities for the diagnosis of dementia. Our study also demonstrates that the Māori-friendly 10/66 dementia protocol has the potential to be used in a dementia-population-based study for Māori in Aotearoa New Zealand.

Objective. Perinatal outcomes in the United States are poor among Hispanics, the country's fastest-growing population. Hispanics experience higher rates of obesity, diabetes, gestational diabetes, preterm birth, and pregnancy-related hypertension, as well as 20% of infant deaths. StartSmarttm, an mHealth app, screens for risk and protective factors. This project translated and culturally adapted StartSmarttm for Spanish-speaking pregnant women. Methods. Using the Beaton process for translation and cultural adaptation, we completed a six-stage process. Stage I: Translation into Spanish, Stage II: Synthesis of the translations, Stage III: Back-translation, Stage IV: Expert committee review, Stage V: Pretesting with Spanish-speaking pregnant women, Stage VI: Appraisal of process. Results. StartSmarttm was acceptable and feasible for use during prenatal visits. Participants reported ease of use and understanding the material. No issues regarding literacy were identified, and participants provided helpful feedback for refining StartSmarttm for Spanish-speaking women. Conclusions. The Beaton process ensures culturally appropriate translation.

Currently, there are estimated to be 70,000 people living with dementia in Aotearoa, New Zealand (NZ). This figure is projected to more than double by 2040, but due to the more rapid growth of older age groups in non-European populations, prevalence will at least triple amongst the NZ Indian population. The impact of dementia in the NZ Indian community is currently unknown. The aim of this study was to explore the lived experiences of NZ Indians living with dementia and their caregivers. Ten caregivers (age range: 41–81) and five people living with mild dementia (age range: 65–77) were recruited from a hospital memory service and two not-for-profit community organisations in Auckland, Aotearoa, NZ. Semi-structured interviews were conducted by bilingual/bicultural researchers and transcribed for thematic analysis in the original languages. Dementia was predominantly thought of as being part of normal ageing. Getting a timely diagnosis was reported as difficult, with long waiting times. Cultural practices and religion played a large part in how both the diagnosis and ongoing care were managed. Caregivers expressed concerns about societal stigma and about managing their own health issues, but the majority also expressed a sense of duty in caring for their loved ones. Services were generally well-received, but gaps were identified in the provision of culturally appropriate services. Future health services should prioritise a timely diagnosis, and dementia care services should consider specific cultural needs to maximise uptake and benefit for Indian families living with dementia.

BACKGROUND: One key element of lung-protective ventilation is the use of a low tidal volume (V(T)). A sex difference in use of low tidal volume ventilation (LTVV) has been described in critically ill ICU patients. OBJECTIVES: The aim of this study was to determine whether a sex difference in use of LTVV also exists in operating room patients, and if present what factors drive this difference. DESIGN, PATIENTS AND SETTING: This is a posthoc analysis of LAS VEGAS, a 1-week worldwide observational study in adults requiring intra-operative ventilation during general anaesthesia for surgery in 146 hospitals in 29 countries. MAIN OUTCOME MEASURES: Women and men were compared with respect to use of LTVV, defined as V(T) of 8 ml kg(−1) or less predicted bodyweight (PBW). A V(T) was deemed ‘default’ if the set V(T) was a round number. A mediation analysis assessed which factors may explain the sex difference in use of LTVV during intra-operative ventilation. RESULTS: This analysis includes 9864 patients, of whom 5425 (55%) were women. A default V(T) was often set, both in women and men; mode V(T) was 500 ml. Median [IQR] V(T) was higher in women than in men (8.6 [7.7 to 9.6] vs. 7.6 [6.8 to 8.4] ml kg(−1) PBW, P*** < 0.001). Compared with men, women were twice as likely not to receive LTVV [68.8 vs. 36.0%; relative risk ratio 2.1 (95% CI 1.9 to 2.1), P*** < 0.001]. In the mediation analysis, patients’ height and actual body weight (ABW) explained 81 and 18% of the sex difference in use of LTVV, respectively; it was not explained by the use of a default V(T). CONCLUSION: In this worldwide cohort of patients receiving intra-operative ventilation during general anaesthesia for surgery, women received a higher V(T) than men during intra-operative ventilation. The risk for a female not to receive LTVV during surgery was double that of males. Height and ABW were the two mediators of the sex difference in use of LTVV. TRIAL REGISTRATION: The study was registered at Clinicaltrials.gov, NCT01601223

The 10/66 dementia protocol was developed as a language and culture-fair instrument to estimate the prevalence of dementia in non-English speaking communities. The aim of this study was to validate the 10/66 dementia protocol in elders of Indian ethnicity born in the Fiji Islands (Fijian-Indian) living in New Zealand. To our knowledge, this is the first time a dementia diagnostic tool has been evaluated in the Fijian-Indian population in New Zealand. We translated and adapted the 10/66 dementia protocol for use in in Fijian-Indian people. Individuals (age ≥ 65) who self-identified as Fijian-Indian and had either been assessed for dementia at a local memory service (13 cases, eight controls) or had participated in a concurrent dementia prevalence feasibility study (eight controls) participated. The sensitivity, specificity, positive predictive value, and Youden’s index were obtained by comparing the 10/66 diagnosis and its sub-components against the clinical diagnosis (reference standard). The 10/66 diagnosis had a sensitivity of 92.3% (95% CI 70.3–99.5), specificity of 93.8% (95% CI 75.3–99.6), positive predictive value of 92.3% (95% CI 70.3–99.5), and negative predictive value of 93.8% (95% CI 75.3–99.6). The study results show that the Fijian-Indian 10/66 dementia protocol has adequate discriminatory abilities to diagnose dementia in our sample. This instrument would be suitable for future dementia population-based studies in the Fijian-Indian population living in Aotearoa/New Zealand or the Fiji-Islands.

Background: Aged residential care (ARC) is a significant cost of dementia care. However, little is known about the predictors of ARC placement in New Zealand (NZ), which is important for service planning and funding. The aim of this study was to investigate the sociodemographic and clinical characteristics that predict future ARC placement among people who received a new diagnosis of dementia at a NZ memory service.Methods: Routinely collected baseline sociodemographic and clinical data in a memory service from 14/06/13 and 14/12/19 were linked with administrative LTC admission data up to 24/1/2020. Survival analysis was carried out using multivariate Cox regression models to determine significant risk factors and their association with ARC placement.Results: A total of 657 NZ European, Māori and Pacific Islander patients were included in the analyses. There were significant differences by ethnicity including age, living situation, comorbidity and ARC placement. Adjusted analyses showed that risk of ARC placement was increased by older age (HR 1.02 per year, 95%CI:1.00–1.05), moderate dementia (HR 1.45, 95%CI:1.05–1.99), severe dementia (HR 2.25, 95%CI:1.33–3.81), and antipsychotics (HR 1.55, 95%CI:1.04–2.32); while risk was reduced in Māori (HR 0.35, 95%CI:0.18–0.68) and Pacific Islanders (HR 0.32, 95%CI:0.20–0.51).Conclusions: Despite having more severe dementia and higher comorbidity, Māori and Pacific Islanders had reduced risks of ARC placement. There is an urgent need to better understand dementia care issues and to ensure culturally safe and responsive dementia services are accessible by Māori and Pacific Islanders living in the community.

Little is known about the lived experience of dementia in the New Zealand Chinese community. This study aims to explore the understanding and experiences of living with dementia in Chinese New Zealanders. Participants were recruited from a memory service and a community dementia day programme. In-depth interviews were conducted by bilingual and bicultural researchers. The recorded interviews were transcribed and thematically analysed. Sixteen people living with dementia and family carers participated in this study. The first theme revealed the lack of understanding of dementia prior to diagnosis, the commonly used term of “brain shrinkage” and that dementia is associated with getting older. The second theme covered the symptoms experienced by people with dementia and how family carers found anhedonia and apathy particularly concerning. The third theme highlighted the tension between cultural obligation and carer stress. The fourth theme is about the stigma attached to dementia. Our results provide some insight into ways to improve dementia care for Chinese New Zealanders, including targeted psychoeducation in the Chinese community to improve awareness and to reduce stigma, access to person-centred interventions, and learning about strategies for healthy ageing to live well with dementia, and emotional support and psychoeducation for family carers to reduce carer stress.

Background As the economic impact of dementia on health and social care increases, governments require disease-specific epidemiological data that will help inform spending and policy decisions. The aim of this study is to examine predictors of mortality in dementia in consecutive referrals to a New Zealand (NZ) memory service that includes Māori, Pacific Islander, and NZ European patients. Methods Date of birth, sex, ethnicity, living situation, cognitive function, dementia subtype, dementia severity, physical comorbidity, and medication data were collected from electronic health records. The resulting data set was linked to administrative data on mortality and last hospital contact dates to allow time-dependent survival analyses. Results The risk of death in people with dementia was increased by age (adjusted HR per year 1.08, 95%CI:1.05-1.12) and lower cognitive score at baseline (adjusted HR for severe impairment:2.54, 95% CI:1.25-5.16), and was reduced by cholinesterase inhibitors (adjusted HR:0.54, 95% CI:0.34-0.88). Compared to NZ Europeans (HR:1.19, 95% CI:0.63-2.25), antipsychotics increased the risk of death three-fold in Māori (adjusted HR:3.62, 95% CI:0.79-16.7) and Pacific Islanders (adjusted HR:2.54, 95%CI:1.10-5.85). Conclusions Further research is required to elucidate the mechanisms underlying the survival rates in Māori and Pacific Islanders living with dementia in NZ,and their increased risk of death if antipsychotics are used.

To describe the biopsychosocial characteristics of a series of Pacific men living in South Auckland with a history of boxing presenting with early onset dementia. We discuss the history of boxing in Pacific people and the possibility of increased risk of early onset dementia in New Zealand Pacific men compared to their European counterparts.We reviewed the files of Pacific men with a history of amateur or professional boxing who presented to our memory and older adult mental health services with early onset dementia over a 45-month period. We gathered relevant information to construct a biopsychosocial paradigm as possible explanation of this phenomenon.We identified a series of eight New Zealand Pacific men with early onset dementia and with a history of boxing. Alcohol was a contributing factor in seven of the eight cases, and vascular risk factors in five.Historical, cultural and socio-economic factors underpin the attraction of some Pacific men to boxing as a sport. Given that New Zealand Pacific peoples may have an earlier onset of dementia than their European counterparts, further research is required to establish whether boxing is a contributory factor. Sports physicians should advise young New Zealand Pacific boxers about the long-term risks associated with their sport.

OBJECTIVE Ethnicity may affect presentation to clinical services in people with dementia; however, no studies have examined this in Māori or Pacific peoples in New Zealand (NZ). Our objective was to examine the routinely collected clinical data from a memory assessment service in South Auckland to examine the presentation of dementia in the major NZ ethnic groups. METHODS A total of 360 patients presenting to a memory service with a new diagnosis of dementia were included in this study. Demographic data (age, sex, and ethnicity) and dementia sub-type and severity were analyzed. RESULTS There were 142 NZ European (mean age: 79.2, SD 7.4), 43 Māori (mean age: 70.2, SD 7.6), 126 Pacific (mean age: 74.3, SD 7.6), and 49 other ethnicities (mean age: 78.0, SD 8.5) presenting with a new diagnosis of dementia. After adjustment for gender and dementia subtype, Māori and Pacific patients were 8.5 and 5.3 years younger than NZ European patients (P

We conducted a long-term experiment in grassland with the aim of elucidating grassland dynamics in relation to variations in rainfall amount and spatial and temporal variation in disturbance. In particular we aimed to increase our understanding of ecosystem dynamics and function, species redundancy, invasion biology, and other related topics. We studied the dynamics of serpentine annual grassland in northern California over the period 1983-2002 in a replicated series of experimental plots comprising controls, gopher exclosures, and aboveground herbivore exclosures. Annual rainfall amount varied greatly during the study period, which included two major El Nino events and a period of prolonged below-average rainfall. Gopher disturbance was highly variable both spatially and temporally but was positively correlated with soil depth. Disturbance was reduced but not eliminated from the gopher exclosures and was significantly increased in the aboveground herbivore exclosures. Grassland dynamics were driven by rainfall amounts and distributions that had the most pronounced effects on the dominant plant species, while gopher disturbance had additional effects on the rarer species. Effects of excluding aboveground herbivores were swamped by a large increase in gopher disturbance within aboveground exclosures. Overall species numbers were reduced during a period of below-average rainfall but recovered in subsequent years. There was a large array of different responses of individual plant species to both rainfall and disturbance. Our results provide support for the "insurance" hypothesis, which suggests that biodiversity buffers ecosystem processes against environmental changes because different species (or phenotypes) respond differently to these changes, leading to functional compensations among species. Here, a species that was at very low abundance levels at the start of the study (Microseris douglasii) temporarily increased in abundance to become one of the dominant species in the grassland following a period of prolonged below-average rainfall. We also observed the repeated invasion of the serpentine grassland by the nonnative grass Bromus hordeaceus, which increased greatly in abundance following both of the major El Nino events. The results emphasize the importance of long-term observations in providing a context for shorter-term studies and allowing analysis of plant community responses to climate variation and disturbance, particularly in the face of ongoing global change.

Background: The National Knowledge Service (NKS) is a National Health Service initiative to make patient and public information available to patients and healthcare professionals. The current study was carried out with a view to determine whether the resources developed by the NKS Tuberculosis Pilot have improved knowledge about tuberculosis among the target group in the short term. Methods: Information resources specifically targeted and developed for homeless sector staff, managers and prison officials were used for this study. Questionnaires were designed to assess a change in the level of knowledge by completing a ‘before’ and ‘after ‘questionnaire. A total of 51 participants took part in the evaluation. McNemar's test for matched pairs was used to determine observed change in knowledge. Results: Staff knowledge on symptoms of tuberculosis (TB) increased significantly after reading the targeted information resources. Knowledge gain for symptoms ranged from 17% (P = 0.007) for weight loss to 45% (P = 0.00001) for persistent fever. Knowledge about general guidelines that are available to this target group also improved, as did knowledge about the potential role of staff in supporting directly observed treatment (by 68% P = 0.00001) and the usual length of TB treatment (by 32% P = 0.0001). Pre-existing knowledge about the infectiousness of TB, risks for transmission and the likely period of hospitalization of patients with TB was high. Conclusions: This study demonstrates that purposefully designed and targeted information leaflets can be used successfully to translate complex information into a simple understandable format and impart knowledge of TB.

This paper reports the results of a survey to investigate nurses' comfort with, and concerns regarding, the electromedical and computer equipment they use in their daily practice. Hospitals were surveyed in Australia, Canada, Great Britain, Singapore, and South Africa. Fourteen hospitals participated and a total of 933 responses were received. The analysis of the responses revealed that nurses are concerned about the training they are receiving on both technologies, the impact that computer time has on their workload, and the reliability and accessibility of these systems and devices.

A study has been made of the reactions in which alcohol or water add to the azomethine group of the copper(II) compounds of the title quadridentate ligands. These have the same chelate ring skeleton as the ethylenediamine analogue, for which the addition reactions were first reported. And, in agreement with its suggested steric origin, the reaction also occurs for these new ligands. However, the solid products are now not invariably the addition products, and its is shown that the product depends, at least partially, on the solubilities of the various possible species, including the non-addition compounds. In addition, the reversibility of the reaction is demonstrated, and it appears that, in spite of the steric strain, the addition product and the non-addition product co-exist in solution in the alcohols. Isomeric forms of several of the compounds have probably been obtained.
