ABSTRACT

OBJECTIVE: Antimicrobial resistance (AMR) is a complex public health issue, with a range of influences across human, animal, and environmental health. Given the complexity of the problem, the diversity of stakeholders, and the failure of current policies to curb AMR worldwide, integrative approaches are needed to identify effective actions. Underpinned by systems thinking and One Health principles, this qualitative study explored how diverse AMR experts in Aotearoa New Zealand perceive the main drivers and effects of AMR. METHODS: Semi-structured interviews with clinical, academic, policy, community, and industry representatives were designed to elicit mental models of the causes and outcomes of AMR across dimensions. RESULTS: Thematic analysis revealed contrasting understandings of AMR causes across four domains: food-producing animals (livestock), healthcare, community, and environment. AMR was often framed as a problem of individual behaviour, despite many implicit references to underlying structural economic influences. The politics of collaboration was a further major underlying theme. The interviews highlighted fundamental connections between AMR and other complex issues, including poverty and environmental pollution. IMPLICATIONS FOR PUBLIC HEALTH: This study brings together the understandings of AMR of transdisciplinary stakeholders, providing some immediate insights for policy makers and setting the foundation for developing a collaborative system model of AMR as a basis for decision-making.

ABSTRACT

BACKGROUND: Climate change is already affecting Aotearoa New Zealand (Aotearoa-NZ). The public health effects are varied and complex, and rural primary care staff will be at the front line of effects and responses. However, little is known about their understanding and experience. OBJECTIVES: To determine understanding, experiences and preparedness of rural general practice staff in Aotearoa-NZ about climate change and health equity. METHODS: A mixed-methods national cross-sectional survey of rural general practice staff was undertaken that included Likert-style and free-text responses. Quantitative data were analysed with simple descriptive analysis and qualitative data were thematically analysed using a deductive framework based on Te Whare Tapa Wha. RESULTS: A proportion of survey respondents remained unsure about climate science and health links, although many others already reported a range of negative climate change health impacts on their communities, and expected these to worsen. Twenty to thirty percent of respondents lacked confidence in their health service's capability to provide support following extreme weather. Themes included acknowledgement that the health effects of climate change are highly varied and complex, that the health risks for rural communities combine climate change and wider environmental degradation and that climate change will exacerbate existing health inequities. CONCLUSIONS: The study adds to sparse information on climate change effects on health in rural primary care. We suggest that tailored professional education on climate change science and rural health equity is still needed, while urgent resourcing and training for interagency disaster response within rural and remote communities is needed.

ABSTRACT

Planetary health has an important role to play in guiding humanity towards a healthy, equitable, and sustainable future. However, given planetary health's dominant colonial and capitalist underpinning ideologies, it risks reinscribing the same exploitative power dynamics that are fundamental drivers of global ecological collapse. In this Personal View, we reaffirm the need for a vision of planetary health grounded in Indigenous epistemologies, which centre relational ecocentric norms and values. We identify key tensions that planetary health scholars, practitioners, and advocates need to engage with to inform action. Finally, we offer suggestions for working progressively towards a decolonial vision of planetary health that recognises our obligations to all our (human and more-than-human) relations. The themes explored in this Personal View bring together our perspectives, strongly centring Indigenous understandings but also referencing ideas and positions emerging from a relational space between Indigenous and non-Indigenous scholars.

ABSTRACT

This study aimed to describe patterns of use and attitudes towards a broad variety of substances for improving academic performance at a New Zealand university. 685 students (from 1800 invited) completed an online questionnaire (38% response rate). They were asked about their lifetime and current substance use for improving academic performance, as well as their reasons for use, attitudes and perceptions of: caffeine, alcohol, dietary supplements, prescription stimulants, other prescription substances, and illicit substances. 80% (95% CI: 76.3, 82.5) reported ever using any substance to help improve academic performance, mainly to stay awake and improve concentration. Caffeine (70%, 95% CI: 66.3, 73.3) and dietary supplements (32%, 95% CI: 28.3, 35.5) were most commonly used. 4% (95% CI: 2.7, 5.9) reported use of prescription stimulants, mostly methylphenidate, and another 4% (95% CI: 2.7, 5.9) reported using illicit substances for improving academic performance. Users of prescription stimulants were more likely than non-users to believe that they were safe, morally acceptable, and that they should be available legally for enhancing academic performance. We close with discussions on broadening the focus of substances for improving academic performance in public health debates. Further qualitative research from small countries is also needed to move towards a place-based approach for clarifying ethical implications, inform policy in universities, and understand how injustices are created through the use of and ability to purchase different substances.

ABSTRACT

Climate change mitigation policies can either facilitate or hinder progress towards health equity, and can have particular implications for Indigenous health. We sought to summarize current knowledge about the potential impacts (co-benefits and co-harms) of climate mitigation policies and interventions on Indigenous health. Using a Kaupapa Maori theoretical positioning, we adapted a validated search strategy to identify studies for this scoping review. Our review included empirical and modeling studies that examined a range of climate change mitigation measures, with health-related outcomes analyzed by ethnicity or socioeconomic status. Data were extracted from published reports and summarized. We identified 36 studies that examined a diverse set of policy instruments, with the majority located in high-income countries. Most studies employed conventional Western research methodologies, and few examined potential impacts of particular relevance to Indigenous peoples. The existing body of knowledge is limited in the extent to which it can provide definitive evidence about co-benefits and co-harms for Indigenous health, with impacts highly dependent on individual policy characteristics and contextual factors. Improving the quality of evidence will require research partnerships with Indigenous communities and study designs that centralize Indigenous knowledges, values, realities and priorities.

ABSTRACT

Climate change is a major threat to public health worldwide. Conversely, well-designed action to mitigate climate change offers numerous opportunities to improve health and equity. Despite this, comprehensive climate action has not been forthcoming within New Zealand. The media plays an important role in shaping public opinion and support for policy change. Previous literature has suggested that certain types of framing may be more effective than others at encouraging support for climate action and policy. This includes positive, personally relevant framing, as well as key journalistic tools which appear counter-intuitive, such as an increase in human interest stories and 'sensationalist' framing. We undertook a qualitative thematic analysis of climate change and health media coverage in two online New Zealand news outlets to understand how the issue was framed, and how it may be framed more effectively to encourage climate action. We compared the framing used by journalists in mainstream media outlet the New Zealand Herald Online (NZHO) with that of contributors to independent news repository site Scoop. Content in both outlets emphasized the threat unchecked climate change poses to health, which overshadowed the positive health opportunities of climate action. The NZHO was more prone to negative framing, and more likely to favour stories which could be sensationalized and were international in scope. We considered the possible effectiveness of the framing we found for attracting greater media attention and encouraging support for climate action and policy.

ABSTRACT

The 2030 Agenda for Sustainable Development and its Sustainable Development Goals (SDGs) represent a historic global linking of health, equity and environmental sustainability. Accumulated evidence suggests that improving urban neighbourhoods to make them safer and more attractive for walking and cycling can accelerate progress towards the SDGs. The pathways to change are complex, non-linear and involve multiple pathways and multiple SDG outcomes, yet the SDG goals are often considered in isolation. Further, there have been few studies of environmental interventions for healthier transport that foreground equity. The aim of this paper is to describe and demonstrate practically how integrated interventions for placemaking and active transport can contribute to a wide range of SDG targets. First, we take an evidence-based approach to describing how such interventions are connected to targets within the SDGs. Second, we propose a complex causal theory of the pathways to change and the inter-relationships between SDGs. Third, we show, with concrete examples, how a case study project in Auckland, New Zealand illustrates these pathways, contributing to achieving the SDG targets, including barriers and challenges. We find that by addressing Goal 11 in particular ways that focus on equity (Goal 10), eight of the other goals can also be advanced. Our causal theory describes one balancing and 12 reinforcing patterns of behaviour that link interventions improvements to neighbourhoods with ten of the SDGs in a complex system. Our case study demonstrates that it is possible to successfully put this causal theory into practice through interventions, but these require strong partnerships between researchers, public health practitioners, policy-makers and communities, long-term evaluation and addressing both physical and social environments.

ABSTRACT

BACKGROUND: The global food system is driving both the climate crisis and the growing burden of noncommunicable disease. International research has highlighted the climate and health co-benefit opportunity inherent in widespread uptake of plant-based diets. Nevertheless, uncertainty remains as to what constitutes healthy and climate-friendly eating patterns in specific world regions. OBJECTIVES: Using New Zealand as a case study, this research investigates the extent to which potential contextual differences may affect the local applicability of international trends. It further examines the potential for demand-end avenues to support a transition toward a healthier, more climate-friendly food system in New Zealand. METHODS: A New Zealand-specific life-cycle assessment (LCA) database was developed by modifying cradle to point-of-sale reference emissions estimates according to the New Zealand context. This food emissions database, together with a New Zealand-specific multistate life-table model, was then used to estimate climate, health, and health system cost impacts associated with shifting current consumption to align with dietary scenarios that conform to the New Zealand dietary guidelines (NZDGs). RESULTS: Whole plant foods, including vegetables, fruits, legumes, and whole grains were substantially less climate-polluting (1.2-1.8 kgCO2e/kg) than animal-based foods, particularly red and processed meats (12-21 kgCO2e/kg). Shifting population-level consumption to align with the NZDGs would confer diet-related emissions savings of 4-42%, depending on the degree of dietary change and food waste minimization pursued. NZDG-abiding dietary scenarios, when modeled out over the lifetime of the current New Zealand population, would also confer large health gains (1.0-1.5 million quality-adjusted life-years) and health care system cost savings (NZ$14-20 billion). DISCUSSION: Guideline-abiding dietary scenarios, particularly those that prioritize plant-based foods, have the potential to confer substantial climate and health gains. This research shows that major contextual differences specific to New Zealand's food system do not appear to cause notable deviation from global trends, reinforcing recent international research. https://doi.org/10.1289/EHP5996.

ABSTRACT

BACKGROUND: EcoHealth and One Health are two major approaches broadly aimed at understanding the links between human, animal, and environment health. There have been increasing calls for convergence between the two. If convergence is desired, greater clarity regarding the underlying theoretical assumptions of both approaches is required. This would also support integrated research to effectively address complex health issues at the human, animal and environment interface. To better understand the areas of overlap and alignment, we systematically compared and contrasted the theoretical assumptions of both approaches. OBJECTIVES: We aimed to gain a more in-depth understanding of the ontological, epistemological and methodological underpinnings of EcoHealth and One Health in order to identify areas of difference and overlap, and consider the extent to which closer convergence between the two may be possible. METHODS: We undertook a scoping review of literature about the ontological, epistemological and methodological positions of EcoHealth and One Health, and analyzed these according to Lincoln, Lynham and Guba's paradigm framework. RESULTS: EcoHealth and One Health are both collaborative, systems-focused approaches at the human, animal, and ecosystem health interface. EcoHealth typically leans towards constructivist-leaning assumptions. Many consider this a necessary aspiration for One Health. However, in practice One Health remains dominated by the veterinary and medical disciplines that emphasize positivist-leaning assumptions. DISCUSSION: The aspirations of EcoHealth and One Health appear to overlap at the conceptual level, and may well warrant closer convergence. However, further shared discussions about their epistemological and ontological assumptions are needed to reconcile important theoretical differences, and to better guide scopes of practice. Critical realism may be a crucial theoretical meeting point. Systems thinking methods (with critical realist underpinnings), such as system dynamics modelling, are potentially useful methodologies for supporting convergent practice.

ABSTRACT

The purpose of this study was to compare the functional outcomes of different types of bilateral mandibular condylar fractures. This was a retrospective study of patients with bilateral mandibular condylar fractures at a level-1 trauma center over a 15-year period. The primary predictor variable was fracture pattern, classified as type I (bilateral condylar), type II (condylar-subcondylar), or type III (bilateral subcondylar). Secondary predictor variables were demographic, injury-related, and treatment factors. Bivariate associations between the predictors and complication rates were computed; a multiple logistic regression model was utilized to adjust for confounders and effect modifiers. Thirty-eight subjects with bilateral condylar injuries met the inclusion criteria. The sample's mean age was 37.6 + 18.2 years, and 16% were female. The most common mechanisms of injury were motor vehicle collisions (53%) and falls (29%). Seventy-four percent had associated noncondylar mandibular fractures, and 32% of cases had concomitant midface fractures. Fifty-three percent of cases were classified as type I, 21% as type II, and 26% as type III. Ten subjects (26%) were managed with open reduction and internal fixation. The average length of follow-up was 4.5 + 6.3 months. After adjusting for confounders and effect modifiers, the type of fracture was a significant predictor of functional complications with type II injuries having the highest likelihood of a poor functional outcome (odds ratio: 7.77, 95% confidence interval: 1.45-41.53, p = 0.02). Asymmetric bilateral mandibular condylar fractures may be associated with an increased risk of poor functional outcomes.

ABSTRACT

PURPOSE: The purpose of this study was to assess whether long-term outcomes were equivalent between computer-assisted design and manufacturing (CAD/CAM) -assisted cranial vault reconstruction performed by an inexperienced surgeon, with fewer years of surgical experience, and traditional reconstruction performed by senior surgeons with many decades of experience. METHODS: An Institutional Review Board-approved retrospective cohort study was performed for all patients with nonsyndromic craniosynostosis between the ages of 1 month to 18 years who received primary, open calvarial vault reconstruction at the Johns Hopkins Hospital between 1990 and 2017. The primary outcome variable was the Whitaker category (I-IV) for level of required revision at the 2-year follow-up visit. Secondary outcomes included estimated blood loss, length of stay, operative time, and postoperative complications. CAD/CAM-assisted surgery was considered noninferior if the proportion of cases requiring any revision (Whitaker II, III, or IV) was no more than 10% greater than the proportion in the traditional surgery group with multivariate logistic regression analysis. t tests and fisher exact tests were used for secondary outcomes. RESULTS: A total of 335 patients were included, with 35 CAD/CAM-assisted reconstructions. CAD/CAM-assisted reconstruction was noninferior to traditional after accounting for patient demographics, type of surgery, and experience level of the plastic surgeon. The traditional group required revision more frequently at 29.0% compared to CAD/CAM at 14.3%. Secondary outcomes were not significantly different between groups, but CAD/CAM had significantly longer average operative times (5.7 hours for CAD/CAM, 4.3 hours for traditional, P < 0.01). CONCLUSION: CAD/CAM technology may lower the learning curve and assist less experienced plastic surgeons in achieving equivalent long-term outcomes in craniofacial reconstruction.

ABSTRACT

BACKGROUND: Efforts to improve health equity should be informed by the best available evidence. However, equity-related research is inconsistently indexed, and uses a variety of terms to describe key concepts, making it difficult to reliably identify all relevant studies. We report the development and validation of a search strategy for studies investigating whether the effects of interventions differ by ethnicity or socio-economic status, using the field of transport and health as an example. METHODS: Adapting previously described methods, we followed four steps: generation of a test set of eligible studies, search strategy development, search strategy validation, and documentation. RESULTS: Drawing from 12 systematic reviews, supplemented by additional studies identified by experts and colleagues, we identified a test set of 11 studies that met our eligibility criteria. We assigned five studies to a development set, which we used to develop and refine our search strategy. We assigned the remaining six studies to a validation set, against which we tested our final search strategy. The final search strategy identified all studies in both validation and development sets. CONCLUSIONS: The validated search strategy derived in this study facilitates the conduct of systematic reviews and other literature searches investigating whether the effects of interventions differ by ethnicity or socio-economic status and may be further developed in future for other equity-focused searches and reviews.

ABSTRACT

BACKGROUND: The purpose of this study was to evaluate patients' views of conflicts of interest (COI) and their comprehension of recent legislation known as the Physician Payments Sunshine Act. This report constitutes the first evaluation of plastic surgery patients' views on COI and the government-mandated Sunshine Act. METHODS: This cross-sectional study invited patients at an academic, general plastic surgery outpatient clinic to complete an anonymous survey. The survey contained 25 questions that assessed respondents' perceptions of physician COI and awareness of the Sunshine Act. Analyses were performed to examine whether perspectives on COI and the Sunshine Act varied by level of education or age. RESULTS: A total of 361 individuals completed the survey (90% response rate). More than half of respondents with an opinion believed that COI would affect their physician's clinical decision-making (n = 152, 52.9%). Although almost three fourths (n = 196, 71.2%) believed that COI should be regulated and COI information reported to a government agency, the majority were not aware of the Sunshine Act before this survey (n = 277, 81.2%) and had never accessed the database (n = 327, 95.9%). More than half of patients (n = 161, 59.2%) stated that they would access a publicly available database with physicians' COI information. A larger proportion of older and educated patients believed that regulation of physicians' COI was important (P < 0.001). CONCLUSIONS: Awareness of and access to plastic surgeon COI information is low among plastic surgery patients. Older and more educated patients believed that transparency regarding COI is important with regard to their clinical care.

ABSTRACT

BACKGROUND: While autologous split calvarial bone is an ideal graft material in cranioplasty, selection of a donor site can be challenging and limited in the reconstruction of complicated cranial defects. Computer-aided design and manufacturing (CAD/CAM) may improve donor-site harvest and contouring and mitigate operative complications in split calvarial bone graft-based cranioplasty for complex patients, but has not previously been studied in this unique setting. METHODS: In this study, a retrospective review of patients who presented to the institution and underwent split-calvarial bone graft-based cranioplasty using CAD/CAM to optimize reconstruction of full-thickness cranial defects ≥30 cm was performed. Patient demographics, complications from past operations, intraoperative variables, and immediate and long-term postoperative outcomes were recorded. The CAD/CAM predicted and actual postoperative graft measurements were compared. RESULTS: Five patients were identified who fulfilled inclusion criteria. Mean age at operation was 43 years and mean size of cranial defect was 69 cm. Mean operative time was 443 minutes and mean estimated blood loss was 450 mL. There were no dural tears, sagittal sinus bleeds, or other intraoperative complications. There were no immediate postoperative complications requiring extended hospital stay or reoperation. The postoperative graft surface areas were on average within 2.1% of the planned graft and this difference was not statistically significant (P = 0.28). All patients expressed satisfaction with cranial contour postoperatively. CONCLUSION: Based on the early experience, the use of CAD/CAM enhances calvarial graft selection and improves contour accuracy in the reconstruction of complex skull defects with minimal complications.

ABSTRACT

BACKGROUND: Currently, there is a paucity of information on the presentation and proper management of pediatric nasoorbitoethmoid fractures. The purpose of this study was to examine the incidence, cause, associated injuries, and management of these fractures. Furthermore, the authors sought to assess outcomes after transnasal wiring or suture canthopexy for type III nasoorbitoethmoid fractures. METHODS: A retrospective cohort review was performed of all patients with nasoorbitoethmoid fractures who presented to a Level I trauma center from 1990 to 2010. Charts and computed tomographic imaging were reviewed, and nasoorbitoethmoid fractures were labeled based on the Markowitz-Manson classification system. Patient fracture patterns, demographics, characteristics, and outcomes were recorded. Univariate and multivariate methods were used to compare groups. RESULTS: A total of 63 pediatric patients were identified in the study period. The sample's mean age was 8.78 ± 4.08 years, and 28.6 percent were girls. The sample included 18 type I injuries, 28 type II injuries, and 17 type III injuries. No significant demographic differences were found between patients with type I, II, and III fractures (p > 0.05). Operative intervention was pursued in 16.7, 46.4, and 82.4 percent of type I, II, and III nasoorbitoethmoid fractures, respectively. In patients with type III nasoorbitoethmoid fractures, no patients with transnasal wiring developed telecanthus. CONCLUSIONS: Pediatric nasoorbitoethmoid fractures are uncommon injuries. Type I fracture can often be treated with close observation. However, type II and III injury patterns should be evaluated for operative intervention. Transnasal wiring is an effective method to prevent traumatic telecanthus deformity in type III fracture patterns.

ABSTRACT

Facial skeletal reconstruction of patients with severe Treacher Collins syndrome (TCS) requires correction of both midface and mandibular deficiencies. Implementing virtual surgical planning can provide an accurate three-dimensional analysis of craniofacial abnormalities, creating calvarial donors that match the anatomy of the desired malar augmentation and facilitating bimaxillary movements, positioning, and fixation in orthognathic surgery. We present a case of an 18-year-old patient with TCS, who underwent staged zygomaticomaxillary reconstruction and double-jaw osteotomy with sliding genioplasty, using computer-assisted surgical planning. Following these operations, the patient achieved not only improved facial harmony but also class I occlusion.

ABSTRACT

Methods for harvest of the temporomandibular joint (TMJ) for transplantation may involve several anatomic levels. The authors aim to assess the feasibility and identify challenges with 2 such methods, resuspending the donor condyles from the recipient glenoid fossae and en bloc harvest of the joint and surrounding temporal bone with plate-fixation to the recipient skull base. Two mock face transplantations were carried out using 4 fresh cadavers. Computed tomography imaging was obtained before and after the procedures to assess the technical success of each method. Both techniques were technically successful, allowing for full passive jaw range of motion following graft transfer and appropriate condyle positioning as assessed by computed tomography. En bloc TMJ harvest allowed for transfer of the entire joint without violating its capsule or altering its biomechanics. The authors found this technique better able to avoid issues with size mismatch between the donor mandible and recipient skull base width. When no such mismatch exists, graft harvest at the level of the mandibular condyle is technically easier and less time consuming. Although both methods of TMJ harvest are technically feasible with acceptable immediate postoperative jaw position and range of motion, the en bloc technique allows for more natural jaw function with less risk of postoperative joint immobility by preserving the joint capsule and its ligamentous support.

ABSTRACT

BACKGROUND: The purpose of this study is to quantify the relationship between social media use and the dissemination of research across nontraditional channels. METHODS: Between June and August of 2016, the authors identified 10 plastic surgery journals with the highest impact factor and their 10 most widely circulated articles. Article age; journal impact factor; "distinguished" article designation; and social media metadata of the first authors, last authors, and journals were incorporated into a multivariate regression model to predict the Altmetric Attention Score, a quantitative measure of popularity across Web-based media platforms. RESULTS: A total of 100 articles, 181 authors, and 10 journals were identified. Older articles tended to be less popular. The article's popularity was associated with the journal's audience size, but not with the author's social media activity. For each 1000 additional Twitter followers of the journal of publication, the Altmetric score is greater by a factor of 1.72 (95 percent CI, 1.076 to 2.749), which is the equivalent of 72 percent more Tweets. There is also a small but statistically significant negative association between the author's social media audience size and the popularity of his or her articles: for every 1000 additional followers, the Altmetric score is lower by a factor of 0.822 (95 percent CI, 0.725 to 0.932), which is the equivalent of 17.8 percent fewer Tweets. CONCLUSION: The popularity of an article across social media platforms is associated with the journal's audience on social media, not with the magnitude of the author's social media activity.

ABSTRACT

BACKGROUND: Relatively few reports have been published investigating the operative management of pediatric zygomaticomaxillary complex fractures. The purpose of this study was to assess pediatric zygomaticomaxillary complex fracture management and associated complications, and potentially describe a standard treatment paradigm for these cases. METHODS: A retrospective cohort review was performed of all patients younger than 15 years presenting to a single institution with zygomaticomaxillary complex fractures from 1990 to 2010. Patient demographics, concomitant injuries, management details, and complications were recorded. Complications were compared among patients by dentition stage, number of fixation points, and identity of fixation sites. RESULTS: A total of 36 patients with 44 unique zygomaticomaxillary complex fractures met the authors' inclusion criteria. Thirty-two fractures exhibited at least 2.0 mm of diastasis along at least one buttress (73 percent), and all but one of these were managed operatively. Among operatively managed patients with deciduous dentition, two-point fixation was associated with a lower overall complication rate compared with one- and three-point fixation (0 percent versus 75 percent and 75 percent; p = 0.01). Furthermore, rigid plate-and-screw fixation at the zygomaticomaxillary buttress was not associated with an increased complication rate in operatively managed patients with deciduous dentition (40 percent versus 50 percent; p = 0.76). CONCLUSIONS: The authors' results suggest that two-point fixation is an effective management strategy for repair of displaced zygomaticomaxillary complex fractures in children. In addition, rigid plate-and-screw fixation at the zygomaticomaxillary buttress in children with deciduous dentition appears to be safe and effective when performed.
