RESUMEN

BACKGROUND: Whether revascularization by percutaneous coronary intervention (PCI) can improve event-free survival and left ventricular function in patients with severe ischemic left ventricular systolic dysfunction, as compared with optimal medical therapy (i.e., individually adjusted pharmacologic and device therapy for heart failure) alone, is unknown. METHODS: We randomly assigned patients with a left ventricular ejection fraction of 35% or less, extensive coronary artery disease amenable to PCI, and demonstrable myocardial viability to a strategy of either PCI plus optimal medical therapy (PCI group) or optimal medical therapy alone (optimal-medical-therapy group). The primary composite outcome was death from any cause or hospitalization for heart failure. Major secondary outcomes were left ventricular ejection fraction at 6 and 12 months and quality-of-life scores. RESULTS: A total of 700 patients underwent randomization - 347 were assigned to the PCI group and 353 to the optimal-medical-therapy group. Over a median of 41 months, a primary-outcome event occurred in 129 patients (37.2%) in the PCI group and in 134 patients (38.0%) in the optimal-medical-therapy group (hazard ratio, 0.99; 95% confidence interval [CI], 0.78 to 1.27; P = 0.96). The left ventricular ejection fraction was similar in the two groups at 6 months (mean difference, -1.6 percentage points; 95% CI, -3.7 to 0.5) and at 12 months (mean difference, 0.9 percentage points; 95% CI, -1.7 to 3.4). Quality-of-life scores at 6 and 12 months appeared to favor the PCI group, but the difference had diminished at 24 months. CONCLUSIONS: Among patients with severe ischemic left ventricular systolic dysfunction who received optimal medical therapy, revascularization by PCI did not result in a lower incidence of death from any cause or hospitalization for heart failure.

RESUMEN

Genetic divergence is the fundamental process that drives evolution and ultimately speciation. Structural variants (SVs) are large-scale genomic differences within a species or population and can cause functionally important phenotypic differences. Characterizing SVs across invasive species will fill knowledge gaps regarding how patterns of genetic diversity and genetic architecture shape rapid adaptation under new selection regimes. Here, we seek to understand patterns in genetic diversity within the globally invasive European starling, Sturnus vulgaris. Using whole genome sequencing of eight native United Kingdom (UK), eight invasive North America (NA), and 33 invasive Australian (AU) starlings, we examine patterns in genome-wide SNPs and SVs between populations and within Australia. Our findings detail the landscape of standing genetic variation across recently diverged continental populations of this invasive avian. We demonstrate that patterns of genetic diversity estimated from SVs do not necessarily reflect relative patterns from SNP data, either when considering patterns of diversity along the length of the organism's chromosomes (owing to enrichment of SVs in subtelomeric repeat regions), or interpopulation diversity patterns (possibly a result of altered selection regimes or introduction history). Finally, we find that levels of balancing selection within the native range differ across SNP and SV of different classes and outlier classifications. Overall, our results demonstrate that the processes that shape allelic diversity within populations is complex and support the need for further investigation of SVs across a range of taxa to better understand correlations between often well-studied SNP diversity and that of SVs.

RESUMEN

The baculovirus expression system is a powerful and widely used method to generate large quantities of recombinant protein. However, challenges exist in workflows utilizing either liquid baculovirus stocks or the Titerless Infected-Cells Preservation and Scale-Up (TIPS) method, including the time and effort to generate baculoviruses, screen for protein expression and store large numbers of baculovirus stocks. To mitigate these challenges, we have developed a streamlined, hybrid workflow which utilizes high titer liquid virus stocks for rapid plate-based protein expression screening, followed by a TIPS-based scale-up for larger protein production efforts. Additionally, we have automated each step in this screening workflow using a custom robotic system. With these process improvements, we have significantly reduced the time, effort and resources required to manage large baculovirus generation and expression screening campaigns.

RESUMEN

INTRODUCTION: Children of people who smoke are more likely to take up smoking themselves. In Aotearoa New Zealand (NZ), adolescent smoking declined dramatically between 2000 and 2016 despite limited change in parental smoking, demonstrating that the cycle can be broken. AIMS AND METHODS: This study aimed to identify modifiable factors associated with never smoking in Year 10 students (14-15 years) who had at least one caregiver who smoked. We used data from the Youth Insights Survey (2016 and 2018, pooled, N = 5,422) and identified students with at least one caregiver (mother, father, grandparent, other caregiver) who smoked (N = 2,205). To investigate modifiable factors potentially associated with nonsmoking we used logistic regression with marginally adjusted prevalence estimates. RESULTS: Overall, 41% of students had at least one caregiver who smoked. In this group, the majority (65%) had never smoked themselves. After adjustment, never-smoking was more prevalent among students attending low-deprivation (more affluent) schools (73% had never smoked) compared to high-deprivation schools (44%); students not exposed to others' smoking inside the home (72%) or in cars (70%) in the past week compared to those exposed (59% and 51%, respectively); and students whose parents would be upset if they were caught smoking (68% vs 49% for those whose parents would not be upset), or who had high self-esteem (69% vs 55% for those with low self-esteem). CONCLUSIONS: Modifiable factors independently associated with non-smoking in adolescents with caregiver(s) who smoked were: nonexposure to smoking inside the home and in cars, parental expectations of nonsmoking, and high self-esteem. IMPLICATIONS: Even in countries like NZ with relatively low adult smoking rates, children's exposure to caregiver smoking may be prevalent, particularly in structurally disadvantaged populations. This study suggests that action to promote smokefree homes and cars, build high self-esteem in young people, and communicate expectations of non-smoking are likely to help children of people who smoke to remain nonsmokers. A comprehensive approach that also addresses "upstream" factors (eg, socioeconomic deprivation) and underlying causes of structural inequity (eg, institutional racism) is needed. Such policy and community action may help to break intergenerational cycles of tobacco use and health inequity.

RESUMEN

INTRODUCTION: Tobacco use is a major threat to health globally. A number of countries have adopted 'endgame goals' to minimise smoking prevalence. The INSPIRED project aims to describe and compare the experiences of the first six countries to adopt an endgame goal. METHODS: Data were collected on the initial experiences of endgame goals in Canada, Finland, Ireland, New Zealand (Aotearoa), Scotland, and Sweden up to 2018. Information was collated on the nature of the endgame goals, associated interventions and strategies, potential enablers and barriers, and perceived advantages and disadvantages. RESULTS: The INSPIRED countries had relatively low smoking prevalences and moderate to strong smokefree policies. Their endgame goals aimed for smoking prevalences of 5% or less. Target dates ranged from 2025 to 2035. Except for New Zealand (Aotearoa), all countries had an action plan to support their goal by 2018. However, none of the plans incorporated specific endgame measures. Lack of progress in reducing inequities was a key concern, despite the consideration of equity in all of the country's goals and/or action plans. Experience with endgame goals was generally positive, however participants thought additional interventions would be required to equitably meet their endgame goal. CONCLUSIONS: There was variation in the nature and approach to endgame goals. This suggests that countries should consider adopting endgame goals and strategies to suit their social, cultural, and political contexts. The experiences of the INSPIRED countries suggest that further and more significant interventions will be required for the timely and equitable achievement of endgame goals. IMPLICATIONS: By 2018, six countries (Canada, Finland, Ireland, New Zealand (Aotearoa), Scotland, and Sweden) had introduced government-endorsed 'endgame goals', to rapidly reduce smoking prevalence to very low levels by a specified date. The nature and implementation of endgame goals was variable. Early experiences with the goals were generally positive, but progress in reducing smoking prevalence was insufficient, particularly for priority groups. This finding suggests more significant interventions ('endgame interventions') and measures to reduce inequities need to be implemented to achieve endgame goals. Variation in the nature and experience of endgame goals demonstrates the importance of designing endgame strategies that suit distinct social, cultural, and political contexts.

RESUMEN

INTRODUCTIONS: An increasing number of countries are adopting the tobacco endgame goal. High levels of public support can accelerate momentum towards implementing tobacco endgame policies. We aimed to conduct a systematic review of public support for tobacco endgame policies and to examine the geographical distribution of studies, support among key populations (adolescents and young adults, people who smoke), and the association between survey design and support. METHODS: We searched Embase, PubMed, Scopus, Web of Science, and Google Scholar for studies published from 2013 onwards. Google was used to search the grey literature. The reference lists of included articles were hand-searched. Studies were included if they reported the proportions of people supporting one or more endgame policies. Risk of bias was assessed using the JBI checklist for prevalence studies. RESULTS: Forty-seven articles were included. Aotearoa/New Zealand and the United States were the countries with the most studies (n=11, respectively). Three-level meta-analyses showed the highest support for mandating a very low nicotine content in tobacco products (76%, 95% CI 61-87%). Meta-regressions were performed to assess the associations of population subgroup and survey design with support levels. The level of support was lower among people who smoke compared to the general population (ß range: -1.59 to -0.51). Support for some policies was lower when neutral or don't know response options were included. CONCLUSIONS: Public support for most tobacco endgame policies was high. IMPLICATIONS: Assessing public support can assist with progressing tobacco endgame policies. Policies that are widely supported by the public may be more politically feasible to implement. Qualitative studies and trial studies can further inform communication and implementation strategies for tobacco endgame policies.

RESUMEN

BACKGROUND: Philip Morris International (PMI) claims to be transforming and has committed to a 'smoke-free' future. In 2020, it announced an 'aspirational' target for reduced cigarette shipments by 2025. METHODS: PMI cigarette shipment data are taken from PMI quarterly financial reports 2008-2023. Trends in these data before and after the 2020 announcement are analysed using linear regression, and auto regressive integrated moving average and error, trend, seasonal time-series models to assess if PMI's 2025 target would be met on pre-existing trends, and if the trend changed after the announcement. These trends are also compared with the global retail market for cigarettes, using sales data from Euromonitor. RESULTS: Findings were consistent across all three models. PMI's shipment target of 550 billion cigarette sticks by 2025 would readily have been met given pre-existing shipment trends. Following the 2020 announcement, the decline in PMI cigarette shipments stalled markedly with a statistically significant change in trend (p<0.001). The current and projected trend to 2025 is consistent with no further decline in cigarette volumes, meaning PMI is unlikely to hit its target. This mirrors a global pattern in which declines in cigarette sales have stalled since 2020. CONCLUSIONS: PMI's 2025 target was not 'aspirational' but highly conservative-it would have been met based on pre-existing trends in declining cigarette shipments. Yet PMI will nonetheless fail to meet that target providing evidence it is not transforming. Stalling of the decline of PMI and global cigarette sales raises significant concerns about progress in global tobacco control.

RESUMEN

BACKGROUND: Racism is an important determinant of health and driver of racial/ethnic health inequities. Experience of racism has been linked to negative healthcare use and experiences although most studies have been cross-sectional. This study examines the relationship between reported experience of racism and subsequent use and experience of health services. METHODS: This is a prospective cohort study design. The 2016/2017 adult New Zealand Health Survey (NZHS) provided the sampling frame and baseline data on exposures, health status and confounders. This stand-alone study invited all exposed individuals to participate when sampled based on their reported experience of racism (ever), stratified by broad ethnic groupings (Maori, Pacific, Asian, European/Other). Equal numbers of unexposed participants were selected for invitation using propensity score matching (propensity to experience racism, based on key available predictive factors). Follow-up was one to two years after NZHS interview. Outcome variables (last 12 months) were: unmet healthcare need (overall, for mental health, for a general practitioner); satisfaction with usual medical centre; and experiences with general practitioners (explaining care, involvement in decision-making, treated with respect/dignity, confidence and trust). Logistic regression models examining the association between experience of racism (at baseline) and health service use and experience (at follow-up) used doubly-robust estimation to weight for propensity scores used in the sampling with additional adjustment for confounders. RESULTS: The study had 2010 participants. Experience of racism (ever) at baseline was associated with higher overall unmet need at follow-up (adjusted OR (aOR) = 1.71, 95% CI 1.31, 2.23), with similar patterns for other unmet need measures. Experience of racism was associated with higher dissatisfaction with a usual medical centre (aOR = 1.41, 95% CI 1.10, 1.81) and with higher reporting of negative patient experiences. CONCLUSION: In line with how racism structures oppression, exposure to racism is largely felt by non-European groups in Aotearoa New Zealand. Experiences of racism potentially lead to poorer healthcare and healthcare inequities through higher unmet need, lower satisfaction and more negative experiences of healthcare. The health system has a critical role to play in addressing racism within healthcare and supporting societal efforts to eliminate racism and ethnic inequities.

RESUMEN

Chromosome rearrangements can result in the rapid evolution of hybrid incompatibilities. Robertsonian fusions, particularly those with monobrachial homology, can drive reproductive isolation amongst recently diverged taxa. The recent radiation of rock-wallabies (genus Petrogale) is an important model to explore the role of Robertsonian fusions in speciation. Here, we pursue that goal using an extensive sampling of populations and genomes of Petrogale from north-eastern Australia. In contrast to previous assessments using mitochondrial DNA or nuclear microsatellite loci, genomic data are able to separate the most closely related species and to resolve their divergence histories. Both phylogenetic and population genetic analyses indicate introgression between two species that differ by a single Robertsonian fusion. Based on the available data, there is also evidence for introgression between two species which share complex chromosomal rearrangements. However, the remaining results show no consistent signature of introgression amongst species pairs and where evident, indicate generally low introgression overall. X-linked loci have elevated divergence compared with autosomal loci indicating a potential role for genic evolution to produce reproductive isolation in concert with chromosome change. Our results highlight the value of genome scale data in evaluating the role of Robertsonian fusions and structural variation in divergence, speciation, and patterns of molecular evolution.

RESUMEN

Housing quality is essential for population health and broader well-being. The World Health Organization Housing and health guidelines highlight interventions that protect occupants from cold and hot temperatures, injuries, and other hazards. The COVID-19 pandemic has emphasized the importance of ventilation standards. Housing standards are unevenly developed, implemented, and monitored globally, despite robust research demonstrating that retrofitting existing houses and constructing high-quality new ones can reduce respiratory, cardiovascular, and infectious diseases. Indigenous peoples, ethnic minorities, and people with low incomes face cumulative disadvantages that are exacerbated by poor-quality housing. These can be partially ameliorated by community-based programs to improve housing quality, particularly for children and older people, who are hospitalized more often for housing-related illnesses. There is renewed interest among policy makers and researchers in the health and well-being of people in public and subsidized housing, who are disproportionately disadvantaged by avoidable housing-related diseases and injuries. Improving the overall quality of new and existing housing and neighborhoods has multiple cobenefits, including reducing carbon emissions.

RESUMEN

BACKGROUND: The Aotearoa/New Zealand Government is aiming to end the tobacco epidemic and markedly reduce Maori:non-Maori health inequalities by legislating: (1) denicotinisation of retail tobacco, (2) 95% reduction in retail outlets and (c) a tobacco free-generation whereby people born after 2005 are unable to legally purchase tobacco. This paper estimates future smoking prevalence, mortality inequality and health-adjusted life year (HALY) impacts of these strategies. METHODS: We used a Markov model to estimate future yearly smoking and vaping prevalence, linked to a proportional multistate life table model to estimate future mortality and HALYs. RESULTS: The combined package of strategies (plus media promotion) reduced adult smoking prevalence from 31.8% in 2022 to 7.3% in 2025 for Maori, and 11.8% to 2.7% for non-Maori. The 5% smoking prevalence target was forecast to be achieved in 2026 and 2027 for Maori males and females, respectively.The HALY gains for the combined package over the population's remaining lifespan were estimated to be 594 000 (95% uncertainty interval (UI): 443 000 to 738 000; 3% discount rate). Denicotinisation alone achieved 97% of these HALYs, the retail strategy 19% and tobacco-free generation 12%.By 2040, the combined package was forcat to reduce the gap in Maori:non-Maori all-cause mortality rates for people 45+ years old by 22.9% (95% UI: 19.9% to 26.2%) for females and 9.6% (8.4% to 11.0%) for males. CONCLUSION: A tobacco endgame strategy, especially denicotinisation, could deliver large health benefits and dramatically reduce health inequities between Maori and non-Maori in Aotearoa/New Zealand.

RESUMEN

BACKGROUND: Transvalvular flow rate (TFR) represents a better reflection of transvalvular flow than the stroke volume index (SVi), and has recently emerged as a useful prognostic tool in patients undergoing surgical aortic valve replacement. There is a paucity of data investigating the role of TFR and its relationship with other clinical or echocardiographic factors in patients undergoing transcatheter aortic valve implantation (TAVI). METHOD: This was a retrospective single-centre study of 629 consecutive patients who underwent TAVI between March 2009 and September 2020. Pre-TAVI low TFR was defined as <200 c/s. The primary study end point was all-cause mortality. RESULTS: Low TFR was observed in 41.8% (263/629) of included patients and was associated with increasing age, low body surface area, hypertension, diabetes, atrial fibrillation, left ventricular (LV) dysfunction, and significant mitral regurgitation. LV function status and severity of aortic valve disease were independent predictors of low TFR. Low TFR was significantly associated with long-term all-cause mortality even after adjustment for other risk factors (adjusted hazard ratio [aHR] 1.44; 95% confidence interval [CI] 1.02-2.03; p=0.038). When data were stratified according to SVi, low TFR was an independent predictor of long-term all-cause mortality in patients with normal SVi (aHR 1.98; 95% CI 1.06-3.69; p=0.032) but not in patients with low SVi (HR 1.23; 95% CI 0.71-2.11; p=0.46; p=0.016 for interaction). CONCLUSIONS: Low TFR is common in patients undergoing TAVI and is an independent predictor of all-cause mortality, particularly in patients with normal SVi.

RESUMEN

Mountain watersheds often contain a mosaic of glacier-, snow-, and rain-fed streams that have distinct hydrologic, temperature, and biogeochemical regimes. However, as glaciers diminish and precipitation shifts from snow to rain, the physical and chemical characteristics that make glacial or snowmelt streams distinct from rain-fed streams will fade. Among the unforeseen consequences of this hydrologic homogenization could be the loss of unique food webs that sustain aquatic consumers. To explore the impacts of a melting cryosphere on stream food webs, we parameterized an aquatic food web model with empirical physicochemical data from glacier-, snow-, and rain-fed streams in southeast Alaska and used the model to simulate the seasonal biomass dynamics of aquatic primary producers and consumers and the growth of juvenile salmon. Model results suggest that glacier-, snow-, and rain-fed streams exhibit seasonal asynchronies in the timing of biofilm and aquatic invertebrate abundance. Although warmer rain-fed streams were more productive during the summer (June through September), colder glacial and snowmelt streams provided enhanced foraging and growth opportunities throughout the remainder of the year. For juvenile salmon that can track peaks in resource abundance within river networks, the loss of meltwater streams strongly constrained modeled growth opportunities by removing spatially and temporally distinct foraging habitats within a watershed. These findings suggest that climate change induced homogenization of high latitude river networks may result in the loss of unique food web dynamics, which could diminish the capacity of watersheds to sustain mobile consumers.

RESUMEN

INTRODUCTION: New Zealand's equity-focused endgame goal (Smokefree 2025) aims to reduce smoking prevalence to minimal levels (ie, <5%) in all population groups by 2025. Inadequate progress has stimulated discussion of innovative measures to reduce prevalence; because few studies have explored how marginalized groups perceive these measures, we addressed this knowledge gap. AIMS AND METHODS: In November and December 2020, we conducted 20 in-depth interviews with people who smoked daily, were aged between 21 and 53, earned less than the median income (NZD33 900), and had marginal or inadequate income sufficiency. We explored participants' smoking history and used an elicitation exercise to probe their views on smokefree policies, including potential endgame measures. We used qualitative descriptive analysis and reflexive thematic analysis to interpret the data. RESULTS: Participants favored increasing personal support to quit and reducing nicotine levels in cigarettes, but generally opposed tobacco excise tax increases and paying people to quit. While many privileged their right to "choose," some recognized that stronger policies could restore the loss of agency addiction caused. Participants felt smoking's powerful addictiveness remained poorly understood, and called for smoking to be recognized and treated as an addiction. CONCLUSIONS: Several participants supported intensifying existing measures or introducing new measures. However, their use of tobacco industry rhetoric to frame smoking as a choice they had made could inadvertently reinforce the stigma they experienced. Reframing cigarettes as an addictive product engineered by a deceptive industry, may make it easier for participants to access the expanded support and compassion they sought. IMPLICATIONS: Policy measures, such as reducing the nicotine level in cigarettes, could support endgame goals; however, greater public understanding of addiction is needed to reduce stigma, support self-efficacy, and foster smoking cessation. Industry denormalization campaigns could challenge views of smoking as a personal choice, decrease self-blame among people who smoke, and present endgame goals as likely to enhance agency.

RESUMEN

BACKGROUND: The Antiplatelet Therapy for Patients Undergoing Transcatheter Aortic-Valve Implantation (POPular TAVI) trial reported comparable composite endpoints of ischemic events using aspirin compared to dual antiplatelet therapy (DAPT). However, this trial was not powered to detect individual differences in ischemic events. We sought to conduct a meta-analysis to compare aspirin to DAPT on ischemic and bleeding events following TAVI. METHODS: The MEDLINE database was searched from inception until September 2020 and only randomized clinical trials of patients receiving antiplatelet therapy following TAVI were included. The treatment effect was reported as rate ratios (RRs) with 95% confidence intervals. RESULTS: Four randomized clinical trials of 1086 TAVI patients were included. There was a 51% reduction in major or life-threatening bleeding with aspirin compared with DAPT [RR 0.49, (95%CI 0.31 to 0.78)]. Aspirin was not associated with an increased risk of death [RR 1.01, (95%CI 0.62 to 1.65)], cardiovascular death [RR 1.15, (95%CI 0.56 to 2.36)], ischemic stroke [RR 0.93, (95%CI 0.51 to 1.70)], or MI [RR 0.53, (95%CI 0.18 to 1.57)]. CONCLUSIONS: This meta-analysis supports the use of aspirin as the optimal antiplatelet strategy following TAVI procedures in reducing bleeding without an increase in ischemic events compared with dual antiplatelet therapy.

RESUMEN

Some tobacco companies claim they are 'transforming' by adopting harm reduction goals or even seeking to achieve a 'smokefree' world. What characterises transformation and whether companies can or are transforming is unclear. Nevertheless, such claims are gaining traction. We critically investigated tobacco industry transformation by exploring the definition and criteria for evaluating transformation, and assessed whether transformation is occurring and feasible.Companies' transformation claims centre on increasing sales of new tobacco and nicotine products like e-cigarettes ('new products') with little attention to reducing sales of more hazardous smoked and oral products ('conventional products').We define a transforming tobacco company as one demonstrating substantial, rapid and verifiable progress towards eliminating the production and sale of conventional tobacco products within 5 years in all markets where it operates.We found no evidence any tobacco company is meeting the three essential criteria of rapidly progressing towards eliminating conventional products, ceasing to obstruct effective tobacco control measures and taking action to minimise smoking uptake and disparities. While some companies are developing new product portfolios, their actions are more consistent with profit maximisation than eliminating conventional product use. This approach is best described as 'pseudo-transformation', designed to delay implementation of effective tobacco control policies. In addition, our analysis suggests replacing conventional products with new nicotine products is unlikely to be a viable long-term business model.Public health practitioners should not rely on tobacco industry claims but should lead the transformation debate, establish credible definitions and criteria, and monitor and assess whether transformation is occurring.

RESUMEN

INTRODUCTION: Aotearoa New Zealand (NZ) plans to introduce a smoke-free generation (SFG) policy, alongside denicotinisation and reducing the availability of tobacco products. The SFG has a clear rationale, yet we know little about how young people, those the policy targets, perceive it. To inform policy design, communication and implementation, we explored how NZ youth perceived the SFG. METHODS: We undertook in-depth interviews with a sample of 20 youth aged 17 or 18 and explored their knowledge of the SFG, and how they perceived its individual and societal implications. We interpreted the data using a reflexive thematic analysis approach. RESULTS: We identified two overarching themes. The first theme, 'societal good and protection from harm', reflected benefits participants associated with the SFG, which outweighed perceptions of lost freedoms. The second theme, 'privileging personal choice', corresponded to two small groups within the sample. The first preferred measures they considered less restrictive, such as increasing the purchase age, and some came to support the SFG as they rationalised their views. The second subgroup expressed more entrenched opposition and felt the SFG deprived them of a choice. CONCLUSIONS: Young people's deep reflection on the SFG led most to view it as liberating rather than restrictive. Communications that avoid prompting heuristic-based responses could encourage youth to reflect on the policy and elicit strong support from the group the SFG aims to benefit.

RESUMEN

BACKGROUND: Between 2010 and 2020, the New Zealand (NZ) Government increased tobacco excise tax by inflation plus 10% each year. We reviewed market structure changes and examined whether NZ tobacco companies shifted excise tax increases to maintain the affordability of lower priced cigarette brands. METHODS: We cluster-analysed market data that tobacco companies supply to the NZ Ministry of Health, created four price partitions and examined the size and share of these over time. For each partition, we analysed cigarette brand numbers and market share, calculated the volume-weighted real stick price for each year and compared this price across different price partitions. We calculated the net real retail price (price before tax) for each price partition and compared these prices before and after plain packaging took effect. RESULTS: The number and market share of Super Value and Budget brands increased, while those of Everyday and Premium brands decreased. Differences between the price of Premium and Super Value brands increased, as did the net retail price difference for these partitions. Following plain packaging's implementation, Super Value brand numbers more than doubled; contrary to industry predictions, the price difference between these and higher priced brands did not narrow. CONCLUSIONS: Between 2010 and 2020, NZ tobacco companies introduced more Super Value cigarette brands and shifted excise tax increases to reduce the impact these had on low-priced brands. Setting a minimum retail price for cigarettes could curtail tobacco companies' ability to undermine tobacco taxation policies designed to reduce smoking.

RESUMEN

BACKGROUND: The paper focuses on the geographical region of Oceania. We highlight the tobacco control leadership demonstrated in this region and describe the challenges and opportunities to achieving country-specific smoke-free goals. RESULTS: Significant achievements include smoke-free nation goals, world-leading initiatives such as plain packaging, and a bold plan by New Zealand to reduce the retail availability of smoked tobacco products and remove virtually all the nicotine from cigarettes and rolling tobacco. There are significant challenges and opportunities before reaching smoke-free status including implementation pathways requiring strong governance and leadership and compliance monitoring and enforcement. CONCLUSIONS: We conclude that achieving a smoke-free Oceania is possible through already existing bold country and regional smoke-free goals, excellent tobacco control leadership, experience and resources, and an understanding of how to work collectively. However, a commitment to focus tobacco control efforts regionally is required to achieve a smoke-free Oceania together.

RESUMEN

OBJECTIVE: This paper explores transnational tobacco companies' (TTCs) long-term policy influence strategies using two case studies, harm reduction and illicit tobacco, to identify lessons for the tobacco control movement and wider efforts to address the commercial determinants of health. METHODS: Evidence from a broad combination of sources including leaked documents and findings from over two decades of TTC monitoring were reviewed for each case study and categorised using the Policy Dystopia Model, focusing on the primary discursive strategy and key instrumental (action-based) strategies used. RESULTS: In both case studies, TTCs seek to advance their interests by engaging primarily in reputation management, coalition management and information management strategies over the long-term to propagate their over-riding discursive strategy-'we've changed, we are part of the solution'-despite clear evidence from both case studies that this is not the case. These strategies are globally coordinated and attempt primarily to reshape norms towards TTC involvement in tobacco control policy and delivery. Findings also suggest that industry denormalisation and the advent of Article 5.3 have led to the TTCs growing use of increasingly complex and opaque 'webs of influence'. CONCLUSIONS: The tobacco control community must develop its own proactive long-term strategies which should include industry denormalisation, new ways to fund research that reduce industry control, and improved transparency measures for research and policy. These findings, including TTC adaptations to Article 5.3, also indicate the need for more structural solutions, addressing corporate power and the underlying political and economic system. These lessons can be applied to other unhealthy commodity industries.
