RESUMO
BACKGROUND: Despite measures to reduce young people's access to electronic cigarettes (ECs), or "vapes", many countries have recorded rising youth vaping prevalence. We summarised studies documenting how underage youth in countries with minimum age sales restrictions (or where sales are banned) report accessing ECs, and outline research and policy implications. METHODS: We undertook a focused literature search across multiple databases to identify relevant English-language studies reporting on primary research (quantitative and qualitative) and EC access sources among underage youth. RESULTS: Social sourcing was the most prevalent EC access route, relative to commercial or other avenues; however, social sourcing dynamics (i.e., who is involved in supplying product and why) remain poorly understood, especially with regard to proxy purchasing. While less prevalent, in-person retail purchasing (mainly from vape shops) persists among this age group, and appears far more common than online purchasing. CONCLUSIONS: Further research examining how social supply routes operate, including interaction and power dynamics, is crucial to reducing youth vaping. Given widespread access via schools and during social activities and events, exploring how supply routes operate and evolve in these settings should be prioritized. Inadequate compliance with existing sales regulations suggest greater national and local policy enforcement, including fines and licence confiscation for selling to minors, is required at the retailer level.

Wilderness medicine training has become increasingly popular among medical professionals with numerous educational opportunities nationwide. Curricula for fellowship programs and for medical student education have previously been developed and published, but a specific curriculum for wilderness medicine education during emergency medicine (EM) residency has not. The objective of this study is to create a longitudinal wilderness medicine curriculum that can be incorporated into an EM residency program. Interest-specific tracks are becoming increasingly common in EM training. We chose this model to develop our curriculum specific to wilderness medicine. Outlined in the article is a 3-year longitudinal course of study that includes a core didactic curriculum and a plan for graduated level of responsibility. The core content is specifically related to the required EM core content for residency training with additions specific to wilderness medicine for the residents who pursue the track. The wilderness medicine curriculum would give residencies a framework that can be used to foster learning for residents interested in wilderness medicine. It would enhance the coverage of wilderness and environmental core content education for all EM residents in the program. It would provide wilderness-specific education and experience for interested residents, allowing them to align their residency program requirements through a focused area of study and enhancing their curriculum vitae at graduation. Finally, given the popularity of wilderness medicine, the presence of a wilderness medicine track may improve recruitment for the residency program.

We present a case of 2-dimensional ultrasound-assisted confirmation of nasogastric tube (NGT) placement using both soft tissue neck and epigastric sonographic imaging. Given our findings and review of the literature, we suggest that bedside ultrasound evaluation of NGT placement is a straightforward, rapid, and novel alternative method to the "gold standard" of a portable chest radiograph in the emergency department (ED).

Anthropogenic environmental change negatively effects human health and is increasing health-care system demand. Paradoxically, the provision of health care, which itself is a substantial contributor to environmental degradation, is compounding this problem. There is increasing willingness to transition towards sustainable health-care systems globally and ensuring that strategy and action are informed by best available evidence is imperative. In this Personal View, we present an interactive, open-access database designed to support this effort. Functioning as a living repository of environmental impact assessments within health care, the HealthcareLCA database collates 152 studies, predominantly peer-reviewed journal articles, into one centralised and publicly accessible location, providing impact estimates (currently totalling 3671 numerical values) across 1288 health-care products and processes. The database brings together research generated over the past two decades and indicates exponential field growth.

Policies to mitigate climate change are essential. The objective of this paper was to estimate the impact of greenhouse gas (GHG) food taxes and assess whether such a tax could also have health benefits in Aotearoa NZ. We undertook a systemised review on GHG food taxes to inform four tax scenarios, including one combined with a subsidy. These scenarios were modelled to estimate lifetime impacts on quality-adjusted health years (QALY), health inequities by ethnicity, GHG emissions, health system costs and food costs to the individual. Twenty-eight modelling studies on food tax policies were identified. Taxes resulted in decreased consumption of the targeted foods (e.g., -15.4% in beef/ruminant consumption, N = 12 studies) and an average decrease of 8.3% in GHG emissions (N = 19 studies). The "GHG weighted tax on all foods" scenario had the largest health gains and costs savings (455,800 QALYs and NZD 8.8 billion), followed by the tax-fruit and vegetable subsidy scenario (410,400 QALYs and NZD 6.4 billion). All scenarios were associated with reduced GHG emissions and higher age standardised per capita QALYs for Maori. Applying taxes that target foods with high GHG emissions has the potential to be effective for reducing GHG emissions and to result in co-benefits for population health.

BACKGROUND: Both human health and the health systems we depend on are increasingly threatened by a range of environmental crises, including climate change. Paradoxically, health care provision is a significant driver of environmental pollution, with surgical and anesthetic services among the most resource-intensive components of the health system. OBJECTIVES: This analysis aimed to summarize the state of life cycle assessment (LCA) practice as applied to surgical and anesthetic care via review of extant literature assessing environmental impacts of related services, procedures, equipment, and pharmaceuticals. METHODS: A state-of-the-science review was undertaken following a registered protocol and a standardized, LCA-specific reporting framework. Three bibliographic databases (Scopus®, PubMed, and Embase®) and the gray literature were searched. Inclusion criteria were applied, eligible entries critically appraised, and key methodological data and results extracted. RESULTS: From 1,316 identified records, 44 studies were eligible for inclusion. The annual climate impact of operating surgical suites ranged between 3,200,000 and 5,200,000 kg CO2e. The climate impact of individual surgical procedures varied considerably, with estimates ranging from 6 to 1,007 kg CO2e. Anesthetic gases; single-use equipment; and heating, ventilation, and air conditioning system operation were the main emissions hot spots identified among operating room- and procedure-specific analyses. Single-use equipment used in surgical settings was generally more harmful than equivalent reusable items across a range of environmental parameters. Life cycle inventories have been assembled and associated climate impacts calculated for three anesthetic gases (2-85 kg CO2e/MAC-h) and 20 injectable anesthetic drugs (0.01-3.0 kg CO2e/gAPI). DISCUSSION: Despite the recent proliferation of surgical and anesthesiology-related LCAs, extant studies address a miniscule fraction of the numerous services, procedures, and products available today. Methodological heterogeneity, external validity, and a lack of background life cycle inventory data related to many essential surgical and anesthetic inputs are key limitations of the current evidence base. This review provides an indication of the spectrum of environmental impacts associated with surgical and anesthetic care at various scales. https://doi.org/10.1289/EHP8666.

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.

INTRODUCTION: Effective models simulating the spread of contagion from provider to other patients, visitors, and rooms in a physically simulated emergency department setting have not been reported, and the effect of personal protective equipment (PPE) on reducing such spread in a simulated emergency department environment has not been quantified. METHODS: We developed a physical model for the spread of an Ebola-like virus. The scenario involved 3 computerized mannequins. One case was a febrile patient after Ebola exposure. Four residents (group A) had only masks and gloves and were initially unaware of exposure history, whereas 4 residents (group C) had known exposure history and had full PPE present in the room. Infected mannequins and surrounding surfaces were coated with Glo Germ, a UV tracer. Fluorescence to UV light was recorded after each scenario. Both tracer groups were compared with a control group (group B) in which no tracer was used to account for background fluorescence. RESULTS: There was transfer of contagion to providers, other patients, nurse and family member confederates, and other treatment rooms. Half of group C used full PPE, and half used partial PPE. There were 3 contaminations in group C with full PPE use, 15 contaminations in group C with partial PPE, and 65 contaminations in group A. CONCLUSIONS: The UV tracer seems to be a useful analog of contaminated bodily fluids because it spread easily and its spread decreased with the use of barrier methods. This model could be used in future studies to measure the effectiveness of different forms of PPE and to study the effectiveness of provider education on appropriately donning and doffing PPE.
