Pharmacists' Attitudes towards Medically Assisted Dying.

AIMS: We aimed to explore pharmacists' attitudes and support toward medically assisted dying (MaiD) through the End of Life Choice Act 2019 (EOLC), their willingness to provide services in this area of practice, and the influences on their decisions. METHODS: The study was conducted via an anonymous, online QualtricsTM survey of pharmacists. Registered New Zealand pharmacists who agreed to receive surveys from the two Schools of Pharmacy as part of their Annual Practicing Certificate renewal were invited to participate through an email with a Qualtrics URL link. The survey contained questions regarding demographics, awareness, knowledge, support for, and attitudes and willingness to participate. RESULTS: Of the 335 responses received, 289 were valid and included in the analysis. Most participants supported legally assisted medical dying (58%), almost a third of participants did not support it (29%), and 13% of respondents were unsure. The five primary considerations that participants perceived to be beneficial included support from legislation, respect for patient autonomy, discussions around morality, ending suffering, and preserving dignity. The main concerns were legal, personal bias, palliation, stigmatisation, and vulnerability. CONCLUSIONS: The influences on the decision by pharmacists to support and willingness to participate in the provision of services consistent with the EOLC are complex and multifactorial. Diverse factors may influence attitudes, of which religion is the most significant factor in not supporting the Act or willingness to participate. Clarity and standardised guidance to ensure that assisted dying queries are appropriately managed in practice would help to address any potential access issues.

Can the Buffalo Concussion Treadmill Test Be Used as a Prognostic Indicator for Patients With Sport-Related Mild Traumatic Brain Injury?

OBJECTIVE: To establish whether time to exercise cessation using the Buffalo Concussion Treadmill Test (BCTT) protocol can be used as a prognostic indicator of recovery after sport-related mild traumatic brain injury (SR-mTBI). DESIGN: Retrospective analysis of prospectively collected data. SETTING: Specialist Concussion Clinic. PARTICIPANTS: Three hundred and twenty one patients presenting between 2017 and 2019 who underwent BCTT for SR-mTBI. INTERVENTIONS: Participants who remained symptomatic at a 2-week follow-up appointment after SR-mTBI underwent BCTT to develop a progressive subsymptom threshold exercise program with fortnightly follow-up until clinical recovery. MAIN OUTCOME MEASURES: Clinical recovery was the primary outcome measure. RESULTS: A total of 321 participants were eligible to participate in this study (mean age 22.94% and 46% female). The BCTT test duration was divided into 4-minute intervals and those who completed full 20 minutes. There was higher probability of clinical recovery in those who finished the entire 20-minute BCTT protocol compared with those who managed 17-<20 minutes (Hazard Ratio, HR 0.57), 13 to 16 minutes (HR 0.53), 9 to 12 minutes (HR 0.6), 5 to 8 minutes (HR 0.4), and 1 to 4 minutes (HR 0.7), respectively. Those seen earlier after injury ( P = 0.009), male patients ( P = 0.116), younger patients ( P = 0.0003), and those with physiological or cervical dominant ( P = 0.416) symptom clusters were more likely to achieve clinical recovery. Fifty percent of those who completed the full BCTT protocol achieved clinical recovery at day 19 post-injury. CONCLUSIONS: The group completing full 20 minutes of BCTT achieved clinical recovery more quickly than those who did not complete full BCTT.

Intuitive Eating Scale-2-EA: Psychometric properties and factor structure of the adapted IES-2 for early adolescents.

PURPOSE: Intuitive Eating (IE) is an approach to eating characterised by attunement to intrinsic cues, and using those cues to guide behaviours related to food and eating. Tylka and Kroon Van Diest's (2008) Intuitive Eating Scale (IES-2) is well-validated in adults, but not yet among early adolescents. The current study was designed to adapt and validate a version suited for use in early adolescence (IES-2-EA). METHODS: Data collected from two independent samples of adolescents aged 11 to 13 (N = 471) were structurally examined using exploratory factor analysis (EFA), with a subsequent confirmatory factor analysis (CFA) to confirm hypothesised model fit. Relationships between scores on the IES-2-EA and validated measures of actual-ideal body size discrepancy, body appreciation, interoceptive awareness, and psychological distress were also examined. RESULTS: The adapted 17-item IES-2-EA had a three-factor structure with several key differences from the original version developed for adults. Moderate-to-strong correlations were found between scores on the IES-2-EA, body appreciation, interoceptive awareness, actual-ideal body size discrepancy, and psychological distress in the first sample of adolescents (n = 245). Secondary CFA showed good model fit in the second sample of adolescents (n = 226). CONCLUSION: The IES-2-EA is well-suited to measure intuitive eating behaviour among early adolescents. The 17 items reflect a three-component structure similar to that seen in adults completing the IES-2. These early data suggest the adapted IES-2-EA has evidence of reliability and validity; it may be an effective measure for research and clinical use.

Microglial and Astrocytic Responses in the Human Midcingulate Cortex in Huntington's Disease.

OBJECTIVE: Patients with Huntington's disease can present with variable difficulties of motor functioning, mood, and cognition. Neurodegeneration occurs in the anterior cingulate cortex of some patients with Huntington's disease and is linked to the presentation of mood symptomatology. Neuroinflammation, perpetrated by activated microglia and astrocytes, has been reported in Huntington's disease and may contribute to disease progression and presentation. This study sought to quantify the density of mutant huntingtin protein and neuroinflammatory glial changes in the midcingulate cortex of postmortem patients with Huntington's disease and determine if either correlates with the presentation of mood, motor, or mixed symptomatology. METHODS: Free-floating immunohistochemistry quantified 1C2 immunolabeling density as an indicative marker of mutant huntingtin protein, and protein and morphological markers of astrocyte (EAAT2, Cx43, and GFAP), and microglial (Iba1 and HLA-DP/DQ/DR) activation. Relationships among the level of microglial activation, mutant huntingtin burden, and case characteristics were explored using correlative analysis. RESULTS: We report alterations in activated microglia number and morphology in the midcingulate cortex of Huntington's disease cases with predominant mood symptomatology. An increased proportion of activated microglia was observed in the midcingulate of all Huntington's disease cases and positively correlated with 1C2 burden. Alterations in the astrocytic glutamate transporter EAAT2 were observed in the midcingulate cortex of patients associated with mood symptoms. INTERPRETATION: This study presents pathological changes in microglia and astrocytes in the midcingulate cortex in Huntington's disease, which coincide with mood symptom presentation. These findings further the understanding of neuroinflammation in Huntington's disease, a necessary step for developing inflammation-targeted therapeutics. ANN NEUROL 2023;94:895-910.

Equity of Maori access to the orthopaedic rehabilitation service of the Bay of Plenty: a cross-sectional survey.

AIMS: Examine the access to the Bay of Plenty rehabilitation service for Indigenous Maori patients undergoing total knee arthroplasty (TKA). Identify structural aspects of the rehabilitation service which promote or restrict access for Maori. METHODS: All patients who underwent TKA in publicly funded Bay of Plenty hospitals in 2021 were retrospectively supplied with a survey. Participants were asked to self-report demographic information and to complete a structured record of the duration, type, and location of their pre and post-operative rehabilitation. RESULTS: Maori patients accessed more rehabilitation (mean = 9.75 total hours) than non-Maori patients (mean = 8.34 total hours). This was in large part driven by a significant home-based component of their rehabilitation (42.9% of Maori respondents received at least some of their rehabilitation at home, compared to 16.4% of non-Maori). CONCLUSIONS: Once engaged with the orthopaedic service and having undergone TKA, rehabilitation access for Maori is comparable to if not greater than that of non-Maori. This is in large part driven by home-based rehabilitation. Practical facilitators which negate transport and financial barriers are an effective method of promoting access to health services for Maori.

Effect of Microdoses of Incisional Antibiotics on the Rate of Surgical Site Infections in Skin Cancer Surgery: A Randomized Clinical Trial.

Importance: Surgical site infections (SSIs) represent a costly and preventable complication of cutaneous surgery. However, there is a paucity of randomized clinical trials investigating antibiotic prophylaxis for reducing SSIs in skin cancer surgery, and evidence-based guidelines are lacking. Incisional antibiotics have been shown to reduce the rate of SSIs before Mohs micrographic surgery, but this represents a small subset of skin cancer surgery. Objective: To determine whether microdosed incisional antibiotics reduce the rate of SSIs before skin cancer surgery. Design, Setting, and Participants: In this double-blind, controlled, parallel-design randomized clinical trial, adult patients presenting to a high-volume skin cancer treatment center in Auckland, New Zealand, for any form of skin cancer surgery over 6 months from February to July 2019 were included. Patient presentations were randomized to one of 3 treatment arms. Data were analyzed from October 2021 to February 2022. Interventions: Patients received an incision site injection of buffered local anesthetic alone (control), buffered local anesthetic with microdosed flucloxacillin (500 µg/mL), or buffered local anesthetic with microdosed clindamycin (500 µg/mL). Main Outcomes and Measures: The primary end point was the rate of postoperative SSI (calculated as number of lesions with SSI per total number of lesions in the group), defined as a standardized postoperative wound infection score of 5 or more. Results: A total of 681 patients (721 total presentations; 1133 total lesions) returned for postoperative assessments and were analyzed. Of these, 413 (60.6%) were male, and the mean (SD) age was 70.4 (14.8) years. Based on treatment received, the proportion of lesions exhibiting a postoperative wound infection score of 5 or greater was 5.7% (22 of 388) in the control arm, 5.3% (17 of 323) in the flucloxacillin arm, and 2.1% (9 of 422) in the clindamycin arm (P = .01 for clindamycin vs control). Findings were similar after adjusting for baseline differences among arms. Compared with lesions in the control arm (31 of 388 [8.0%]), significantly fewer lesions in the clindamycin arm (9 of 422 [2.1%]; P < .001) and flucloxacillin (13 of 323 [4.0%]; P = .03) arms required postoperative systemic antibiotics. Conclusions and Relevance: This study evaluated the use of incisional antibiotics for SSI prophylaxis in general skin cancer surgery and compared the efficacy of flucloxacillin vs clindamycin relative to control in cutaneous surgery. The significant reduction in SSI with locally applied microdosed incisional clindamycin provides robust evidence to inform treatment guidelines in this area, which are currently lacking.

Operative Autonomy in a Gender-Balanced Cohort of Surgical Trainees.

BACKGROUND: Gender inequity continues to be a major focus of improvements within surgical education. Female trainees are fewer and experience reduced quality of surgical training. Prior studies have demonstrated that surgical autonomy for female trainees in a range of surgical disciplines is less than that of male trainees. As a unique example among Australasian specialty training boards, the New Zealand Board of Plastic and Reconstructive Surgery has boasted a gender-balanced cohort of surgical trainees since 2013. The authors sought to examine the effect of gender on surgical autonomy in a cohort of trainees where gender balance has been achieved. METHODS: A retrospective cohort study was undertaken. Anonymized logbook data for New Zealand plastic surgery trainees were analyzed, for the study period, consisting of rotations from December of 2013 to June of 2020. Self-reported levels of trainee supervision were compared against gender. Outcomes were tested using multivariate analysis. RESULTS: Thirty-eight trainees were included in the study (58% female), with a total of 81,178 cases recorded over the 6.5-year study period. No overall statistically significant difference in surgical autonomy was identified when analyzed by gender. Male and female trainees showed similar trends of increasing surgical autonomy throughout the course of surgical training. CONCLUSIONS: In a cohort of surgical trainees that has reached gender balance, the negative impact of gender on surgical autonomy was not identified. These findings suggest that where women make up an equal proportion of trainees, the implicit gender bias within surgical training may be ameliorated.

Process evaluation of in-person, news and social media engagement of a community-based programme Brown Buttabean Motivation (BBM): a research protocol.

INTRODUCTION: The community group Brown Buttabean Motivation (BBM) initially began to assist Auckland Pasifika and Maori to manage weight problems, predominantly through community-based exercise sessions and social support. BBM's activities expanded over time to include many other components of healthy living in response to community need. With advent of the COVID-19 pandemic, BBM outreach grew to include a foodbank distributing an increasing amount of donated healthy food to families in need, a community kitchen and influenza and COVID-19 vaccine drives. A strong social media presence has served as the main means of communication with the BBM community as well as use of traditional news media (written, radio, television) to further engage with vulnerable members of the community. METHODS AND ANALYSIS: The study aims to conduct mixed method process evaluation of BBM's community engagement through in-person, social and news media outreach activities with respect to the health and well-being of Pasifika and Maori over time. The project is informed by theoretical constructs including Pacific Fa'afaletui and Fonofale and Maori Te Whare Tapa Wha Maori research frameworks and principles of Kaupapa Maori. It is further framed using the concept of community-driven diffusion of knowledge and engagement through social networks. Data sources include in-person community engagement databases, social and news media outreach data from archived documents and online resources. Empirical data will undergo longitudinal and time series statistical analyses. Qualitative text thematic analyses will be conducted using the software NVivo, Leximancer and AntConc. Image and video visual data will be randomly sampled from two social media platforms. The social media dataset contains almost 8000 visual artefacts. ETHICS AND DISSEMINATION: Ethics approval obtained from University of Auckland Human Participants Ethics Committee UAHPEC 23456. Findings will be published in peer-reviewed publications, disseminated through community meetings and conferences and via BBM social network platforms. TRIAL REGISTRATION NUMBER: ACTRN 12621 00093 1875.

The Impact of a Pharmacist-Led Intravenous to Oral Switch of Metronidazole: A Before-and-After Study.

(1) Background. Intravenous (IV) to oral switch (IVOS) of antibiotics can reduce the length of hospitalisation, risk of IV catheter complications, and hospital costs. Pharmacists can play an instrumental role in implementing an IVOS initiative. The aim of this study is to evaluate the impact of pharmacist-led IVOS of metronidazole. (2) Method. This was an observational study conducted in a New Zealand hospital. During a 3-month intervention period, pharmacists identified patients receiving IV metronidazole; then initiated an IVOS for patients who met the criteria. The comparator groups were patients who were not switched by pharmacists in the post-intervention (post-IVOS) group, or patients treated with either IV or oral metronidazole prior to the intervention (pre-IVOS). Primary outcome measures were switch rate and duration of IV metronidazole treatment. Secondary outcome measures were readmission and/or repeat surgery within 90 days of discharge and the length of hospital stay. (3) Results. In total, 203 patients were included: 100 in the pre-IVOS and 103 in the post-IVOS groups. Pharmacists switched 63/93 (67.7%) of eligible patients to oral metronidazole in the post-IVOS period. Only 9/89 (10.1%) of IVOS eligible patients were switched in the pre-IVOS group. In the post-IVOS group, the mean duration of IV metronidazole treatment in patients switched by pharmacists was shorter than in those who were not switched by pharmacists (2.5 ± 2.8 days vs. 4.8 ± 5.9 days, p = 0.012). No significant difference was found in readmission or repeat surgery within 90 days of discharge for patients switched by pharmacists versus patients who were not switched by pharmacists. (4) Conclusion. Our data have demonstrated successful implementation of the hospital-approved pharmacist-led IVOS service.

The utility of hyperspectral imaging in patients with chronic venous disorders.

OBJECTIVE: The underlying pathophysiology of lower limb changes in chronic venous disorders (CVD) may involve alteration in microcirculation and tissue oxygenation. Hyperspectral imaging (HSI) is a noninvasive tool that is used clinically to measure transcutaneous oxygenation in peripheral artery disease and diabetic foot disease. However, there has been little application in venous disease. The aim of this study was to determine if transcutaneous oxygenation in the lower limb, as measured by HSI, changes depending on the clinical component of the Clinical-Etiological-Anatomical-Pathophysiological (CEAP) classification in CVD. METHODS: This was an observational study of patients with CVD recruited from a vascular specialist clinic at a tertiary hospital from January 2020 to January 2021. Participants were allocated to eight groups according to the clinical component of CEAP classification of CVD. Baseline demographic and risk factor information were collected. Transcutaneous oxygenation was measured using HSI at seven sites around the foot and gaiter area in the supine and standing position. Participants rested supine for 15 minutes before the supine measurements and then stood for 15 minutes before the standing measurements. Tissue oxygenation was analyzed over a fixed circular surface area of 79 mm2 at the target location. Calculations of oxyhemoglobin level (artificial unit [AU]), deoxyhemoglobin level (AU), oxygen saturation (%), and temperature (°C) were obtained. The Northern Ethics Committee (18/NTA/78) approved this conduct of the study and participants signed written consent forms. RESULTS: There were 94 participants (164 lower limbs) included in the study. The median age was 59 years and 59 participants (63%) were women. At all sites except the heel, deoxyhemoglobin measurements increased in the standing position compared with the supine position (P < .001). In the gaiter region, there was nearly a doubling in deoxyhemoglobin level at 5 cm above the medial malleolus (supine 43.88 AU vs standing 80.46 AU; P < .001) and 5 cm above the lateral malleolus (supine 46.33 AU vs standing 87.72 AU; P < .001). When measurements were stratified by clinical class of the CEAP classification, there was a greater increase in deoxyhemoglobin levels with increasing clinical class in the standing position (P < .001). This finding was not observed in the supine measurements. CONCLUSIONS: In CVD, HSI shows an increase in deoxyhemoglobin in the standing compared with supine position, particularly in the gaiter region. Furthermore, standing deoxyhemoglobin increases as the CEAP clinical class increases. Thus, this noninvasive tool may respond to venous physiology and may supplement the clinical class of the CEAP classification system.

Co-designing an intervention to prevent rheumatic fever in Pacific People in South Auckland: a study protocol.

BACKGROUND: Rheumatic fever is an autoimmune condition that occurs in response to an untreated Group A Streptococcus throat or skin infection. Recurrent episodes of rheumatic fever can cause permanent damage to heart valves, heart failure and even death. Maori and Pacific people in Aotearoa New Zealand experience some of the highest rates globally, with Pacific children 80 times more likely to be hospitalised for rheumatic fever and Maori children 36 times more likely than non-Maori, non-Pacific children. Community members from the Pacific People's Health Advisory Group, research officers from the Pacific Practice-Based Research Network and University of Auckland researchers identified key health priorities within the South Auckland community that needed to be addressed, one of which was rheumatic fever. The study outlined in this protocol aims to co-design, implement, and evaluate a novel intervention to reduce rheumatic fever rates for Pacific communities in South Auckland. METHODS: This participatory mixed-methods study utilises the Fa'afaletui method and follows a three-phase approach. Phase 1 comprises a quantitative analysis of the rheumatic fever burden within Auckland and across New Zealand over the last five years, including sub-analyses by ethnicity. Phase 2 will include co-design workshops with Pacific community members, families affected by rheumatic fever, health professionals, and other stakeholders in order to develop a novel intervention to reduce rheumatic fever in South Auckland. Phase 3 comprises the implementation and evaluation of the intervention. DISCUSSION: This study aims to reduce the inequitable rheumatic fever burden faced by Pacific communities in South Auckland via a community-based participatory research approach. The final intervention may guide approaches in other settings or regions that also experience high rates of rheumatic fever. Additionally, Maori have the second-highest incidence rates of rheumatic fever of all ethnic groups, thus community-led approaches 'by Maori for Maori' are also necessary. TRIAL REGISTRATION: The Australian New Zealand Clinical Trial Registry has approved the proposed study: ACTRN12622000565741 and ACTRN12622000572763 .

Study protocol for evaluating Brown Buttabean Motivation (BBM): a community-based, Pacific-driven approach to health.

BACKGROUND: Buttabean Motivation (BBM) is a Pacific-led organisation which aims to reduce obesity amongst Pacific and Maori people in New Zealand enabling them to choose a healthy and active life-style for the duration of their lives, their children, their wider family and the community. BBM offers a holistic approach to weight loss, recognising that mental health, family and cultural factors all play essential and critical role in nutrition and physical activity patterns. This study aims to evaluate the effectiveness of BBM for sustained health and wellbeing outcomes among its predominantly Pacific and Maori participants for both general BBM members and those with morbid obesity attending the 'From the Couch' programme. METHODS: Quasi-experimental pre-post quantitative cohort study design with measured or self-reported weight at various time intervals for both cohorts. Weight will be analysed with general linear mixed model for repeated measures, and compared with a prediction model generated from the literature using a mixed method meta-analysis. The secondary outcome is change in pre- and post scores of Maori scale of health and well-being, Hua Oranga. DISCUSSION: Multiple studies have shown that many diet and physical activity programmes can create short-term weight loss. The fundamental question is whether BBM members maintain weight loss over time. In New Zealand, Pacific and Maori engagement in health enhancing programmes remains an important strategy for achieving better health and wellbeing outcomes, and quality of life. Internationally, the collectivist cultures of indigenous and migrant and minority populations, living within dominant individualist western ideologies, have much greater burdens of obesity. If BBM members demonstrate sustained weight loss, this culturally informed community-based approach could benefit to other indigenous and migrant populations.

Age-Adjusted Reference Values for Prostate Specific Antigen - A Systematic Review and Meta-Analysis.

OBJECTIVES: To systematically evaluates the evidence on ethnic differences in age-adjusted reference values of PSA. MATERIALS AND METHODS: In concordance with the Preferred Reporting Items for Systematic Review and Meta-analysis statement, a review of English articles using Medline, Embase and Cochrane databases, from inception to December 2019 was conducted. Studies that reported the PSA upper reference value as 95th percentile of the cohort distribution, in healthy men aged 40 to 79, were included. Methodological quality was assessed with a modified version of the Agency for Healthcare Research and Quality checklist for cross-sectional studies. RESULTS: Forty-three studies examining 325,514 participants were included in the analysis. These were published between 1993 and 2018. Majority were prospective observational studies and reported the reference values in ten-year age intervals. Only five reports directly compared ethnic differences in PSA values. Due to missing data, six studies were not considered in the quantitative synthesis. For the remainder (37/43), heterogeneity in PSA reference values was considerable (Higgin's index = 99.2%), with age and ethnicity being the sole identified significant contributors. Accordingly, the pooled upper limits for PSA reference values were 2.1, 3.2, 4.9 and 6.5 ng/ml for men in their 40 s, 50 s, 60 s, and 70 s, respectively. CONCLUSION: Moderate quality evidence suggest that upper PSA reference limits increased with age and significant ethnic differences were present.

Intuitive Eating Scale-2: psychometric properties and clinical norms among individuals seeking treatment for an eating disorder in private practice.

PURPOSE: Intuitive Eating (IE) is an approach to eating designed to facilitate a positive relationship with food. Its use in clinical settings and in the community is rapidly growing in popularity. The Intuitive Eating Scale 2 (IES-2) is a widely used measure that indexes intuitive eating motivations and behaviour, however evidence of its validity in populations with clinical eating disorders remains scarce. The objective of the proposed study was thus to evaluate the factor structure of the IES-2 in a large sample of individuals seeking treatment for eating disorders in private practice. METHODS: Data collected from 569 women and men aged 12-68 years seeking treatment for an eating disorder in one of eight specialist private outpatient eating disorder clinics were examined using confirmatory factor analysis (CFA). Relationships between IES-2 scores and measures of psychopathology were also examined. RESULTS: Results were relatively consistent with the purported four-factor structure of the IES-2. The measure displayed strong construct validity and good internal consistency. Scores on the IES-2 were inversely associated with scores of depression, anxiety, and disordered eating, providing evidence for divergent validity of the measure. Clinical norms are provided for anorexia nervosa (AN) spectrum disorders and bulimia nervosa (BN) spectrum disorders, as well as for the clinical sample as a whole. CONCLUSION: Findings suggest that the IES-2 may be an appropriate measure for evaluating behaviours relating to IE in community outpatient eating disorder settings, and provide further evidence for the association between IE and positive health outcomes. LEVEL OF EVIDENCE: III, evidence obtained from well-designed cohort or case-control analytic studies.

Design and implementation of a Pacific intervention to increase uptake of urate-lowering therapy for gout: a study protocol.

BACKGROUND: Gout is a painful chronic disease which disrupts work and family life and can lead to chronic joint damage. Pacific people in Aotearoa/New Zealand experience significant inequities, with over three times the gout prevalence of the non-Pacific non-Maori populations. Pacific people receive less regular urate-lowering drugs to prevent gout flare-ups, and have nine times the hospitalisation from gout compared with non-Pacific non-Maori people. Rates for Indigenous Maori lie between Pacific and non-Pacific non-Maori. A long-established Collective comprising community members from the Pacific People's Health Advisory Group, clinical staff from the Pacific Practice-Based Research Network, and University of Auckland researchers have identified that improving Pacific urate-lowering therapy use as the research question of prime importance for improved health outcomes of Pacific people in South Auckland. Building on the existing knowledge, this study aims to develop, implement and evaluate a novel innovative intervention to improve the uptake of urate-lowering therapy by Pacific patients with gout. METHODS: Three-phase mixed methods co-design study using the Fa'afaletui research framework following the STROBE statement. Phase1 is observational times series of prevalence of patients with gout, proportion with urate blood-level monitoring and use of urate-lowering medication over past 5 years. In Phase 2 the Collective will workshop new interventions to address previous uptake barriers, using culturally-appropriate Talanga communications with results synthesised in line with Kakala principles. The designed intervention will be implemented and process and outcome evaluations conducted. Finally, an implementation framework will be produced to facilitate further roll-out. DISCUSSION: The study aims to enhance health and reduce inequities for Pacific people, contribute to creation of Pacific health knowledge and translation of research findings into Pacific health gains. Potential longer-term impact is a gout-management pathway for use throughout Aotearoa/New Zealand. Maori have similar issues with high gout prevalence and low urate-lowering therapy use hence the intervention is likely to translate to Maori healthcare. The project will contribute to Pacific research capacity and capability-building as well as general upskilling of community and practice members involved in the co-design processes. TRIAL REGISTRATION: The Australian New Zealand Clinical Trial Registry is in process, request number 38206, 1-09-2021.

The effect of age and sex on the expression of GABA signaling components in the human hippocampus and entorhinal cortex.

Gamma-aminobutyric acid (GABA) is the primary inhibitory neurotransmitter in the nervous system. The GABA signaling system in the brain is comprised of GABA synthesizing enzymes, transporters, GABAA and GABAB receptors (GABAAR and GABABR). Alterations in the expression of these signaling components have been observed in several brain regions throughout aging and between sexes in various animal models. The hippocampus is the memory centre of the brain and is impaired in several age-related disorders. It is composed of two main regions: the Cornu Ammonis (CA1-4) and the Dentate Gyrus (DG), which are interconnected with the Entorhinal Cortex (ECx). The age- and sex-specific changes of GABA signaling components in these regions of the human brain have not been examined. This study is the first to determine the effect of age and sex on the expression of GABA signaling components-GABAAR α1,2,3,5, ß1-3, γ2, GABABR R1 and R2 subunits and the GABA synthesizing enzymes GAD 65/67-in the ECx, and the CA1 and DG regions of the human hippocampus using Western blotting. No significant differences were found in GABAAR α1,2,3,5, ß1-3, γ2, GABABR R1 and R2 subunit and GAD65/76 expression levels in the ECx, CA1 and DG regions between the younger and older age groups for both sexes. However, we observed a significant negative correlation between age and GABAAR α1subunit level in the CA1 region for females; significant negative correlation between age and GABAAR ß1, ß3 and γ2 subunit expression in the DG region for males. In females a significant positive correlation was found between age and GABAAR γ2 subunit expression in the ECx and GABABR R2 subunit expression in the CA1 region. The results indicate that age and sex do not affect the expression of GAD 65/67. In conclusion, our results show age- and sex-related GABAA/BR subunit alterations in the ECx and hippocampus that might significantly influence GABAergic neurotransmission and underlie disease susceptibility and progression.

Morbidity following thyroid and parathyroid surgery: Results from key performance indicator assessment at a high-volume centre in New Zealand.

BACKGROUND: Complications following thyroid/parathyroid surgery include recurrent laryngeal nerve (RLN) injury, hypocalcaemia and return to theatre for haematoma evacuation. Rates of these form the basis of key performance indicators (KPI). An endocrine database, containing results from 1997, was established at the North Shore Hospital in Auckland, New Zealand. We aimed to measure complication rates by procedure (thyroid and parathyroid), explore a temporal change in our unit and compare our results against international literature. METHODS: A retrospective review of the database between July 1997 and February 2020 was performed. The results for each KPI were analysed in total and over consecutive time periods. A review of the literature was carried out to find international complication rates for comparison. A cumulative sum (CUSUM) analysis was performed to give visual feedback on performance. RESULTS: There were 1062 thyroidectomies and 336 parathyroidectomies from July 1997 to February 2020. Thyroid surgery results found rates of temporary/permanent RLN injury of 1.9%/0.3%, temporary/permanent hypocalcaemia of 22.3/2.5%, and return to theatre for haematoma evacuation of 1.1%. Parathyroid surgery results were, temporary RLN injury of 0.8% (no permanent injury), temporary/permanent hypocalcaemia of 1.7%/0.4%, and return to theatre for haematoma evacuation of 0.3%. CUSUM analysis found KPI results to be comparable with international literature. CONCLUSION: Our unit's KPI results are comparable to published results in the literature. The use of this clinical database will help in future monitoring of performance and help drive improvement in the service. Embedding prospective data collection as routine practice allows for continuous improvement for the unit.

Primary medication non-adherence to analgesics and antibiotics at Counties Manukau Health Emergency Department.

AIM: To measure primary medication non-adherence to antibiotics, paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs) in patients discharged from Counties Manukau Health Emergency Department (CMH-ED). METHOD: A retrospective observational study based on 1,600 discharged patients' data collected between 28 April-6 May and 28 July-9 August 2014. Data were included for patients who were residents within the Auckland Regional Public Health Service boundaries, presented to CMH-ED and were discharged with a prescription. RESULTS: Of 992 patients, 48.5% did not have at least one medication on their discharge prescription filled. Patients were mostly born in New Zealand (66.5%), of Pacific Island descent (42.8%), living in the most socioeconomically deprived areas (78.1%) and under 10 years of age (32.6%). Filling rates significantly increased with >1 prescribed item (p≤0.01). NSAIDs were significantly more likely to be filled compared with paracetamol (59.9% vs 51.3%, p=0.034); antibiotics were significantly more likely to be filled than all other medicines (80.4%, p<0.001). The most significant predictors for non-adherence when accounting for number and types of medications were patients 10-44 years (p<0.05) and smokers (p<0.01). CONCLUSIONS: Age, smoking and number of prescribed medications were predictors of non-adherence to medication type. Further research is warranted to assess whether changes to prescription co-payments affect the rate of nonadherence.

Clinical factors associated with successful embolization of lower gastrointestinal bleeding.

AIM: To develop a model of clinical factors that may predict: (1) technically and clinically successful embolization of a bleeding vessel at digital subtraction angiography (DSA) for lower gastrointestinal bleed (LGIB); (2) a negative DSA in the presence of positive CT-mesenteric angiography (CTMA) for LGIB. METHODS: A retrospective cohort study of all DSAs conducted with intent for embolization for acute LGIB over a 10-year period was undertaken. Pre-procedural and intra-procedural clinical variables were evaluated using uni- and multi-variate analysis. RESULTS: One hundred and twenty-three DSAs were evaluated. Technical success was 81% and clinical success 78% where DSA was positive. Technical success was associated with super-selective approach, contrast extravasation on CT, haemoglobin drop, anatomical source and time from CT to DSA on univariate analysis. On multivariate analysis, time from CT to DSA was significant with a higher success probability within 120 min with different factors being salient depending on degree of delay. Clinical success was only associated with activated partial thromboplastin time (<27.5 s). A negative DSA was associated with anatomical source, haemodynamic stability, platelet count and time from CT to DSA on univariate analysis. The latter three remained so on multivariate analysis. CONCLUSION: A triaging approach to utilizing emergency DSA may be helpful. If prolonged delay between CT and DSA is anticipated, with haemodynamic stability and a near-normal platelet count, the DSA may not be fruitful. Technical success may be more likely if DSA occurs within 120 min. Clinical success may be more likely if activated partial thromboplastin time is within normal range.
