Associations of educational and marketing messages with beliefs about nicotine and reduced nicotine cigarettes.

INTRODUCTION: Widespread misperceptions about nicotine may have unintended effects on public health. We examined associations between existing messages about nicotine or tobacco and beliefs about nicotine and reduced nicotine cigarettes (RNC). METHODS: 2962 U.S. 18-45-year-olds were randomized in a May 2022 web-based survey to view one of 26 text-based messages about tobacco or nicotine from three sources: ongoing research (n = 8), messages authorized by FDA for VLN cigarettes (n = 6), and FDA's "From Plant to Product to Puff" campaign (n = 12); six messages from FDA's campaign did not reference nicotine and were treated as the reference source. Analyses examined associations between messages, grouped by source and individually, with beliefs about nicotine and RNC addictiveness and harms. RESULTS: Relative to FDA messages that did not reference nicotine, all message sources were associated with greater odds of a correct belief about nicotine (Odds Ratios [ORs] = 1.40-1.87, p's < 0.01); VLN messages were associated with greater correct beliefs about RNC addictiveness (b = 0.23, p < .05). No campaign produced greater correct beliefs about RNC harms. At the individual level, only five messages were associated with a correct belief about nicotine (ORs = 2.12-2.56, p-values < .01), and one with correct beliefs about RNC harms (b = 1.09, p < .05), vs. the reference message. CONCLUSIONS: Few existing messages improved understanding of the risks of nicotine separately from the risks of combustible products. Communication research is needed to promote greater public understanding of nicotine while minimizing unintended effects on nicotine and tobacco use.

A 3D hanging spheroid-filter plate for high-throughput drug testing and CAR T cell cytotoxicity assay.

Tumour spheroids are widely used in immune cell cytotoxicity assays and anticancer drug testing, providing a physiologically relevant model replicating the tumour microenvironment. However, co-culture of immune and tumour cells complicates quantification of immune cell killing efficiency. We present a novel 3D hanging spheroid-filter plate that efficiently facilitates spheroid formation and separates unbound/dead cells during cytotoxicity assays. Optical imaging directly measures the cytotoxic effects of anti-cancer drugs on tumour spheroids, eliminating the need for live/dead fluorescent staining. This approach enables cost-effective evaluation of T-cell cytotoxicity with specific chimeric antigen receptors (CARs), enhancing immune cell-based assays and drug testing in three-dimensional tumour models.

Dual-Vaping of Nicotine and Cannabis Among Adults Who Currently Use Tobacco Products in Five New England States.

INTRODUCTION: Current measures of vaping behaviors in the U.S. do not distinguish what substances participants are vaping and to what extent they are dual-vaping nicotine and cannabis. This study describes the use of new survey questions that more specifically ask whether participants who vape are vaping nicotine, cannabis, cannabidiol (CBD), or another substance. AIMS AND METHODS: Adults, who reported any past 30-day tobacco use, from five New England states participated in an online survey from April 2021 to July 2022. Participants who vaped were asked, "Have you used any of the following vape substances in the past 30 days?" with the possible responses of nicotine, cannabis, CBD, other, and "don't know." Dual use of both nicotine and cannabis was defined as the vaping of both nicotine and cannabis and/or CBD in the past 30 days, operationalized as a dichotomous outcome. Data were collected in monthly, repeated cross-sectional waves. Multinomial logistic regression was used to examine correlates of dual-vaping. RESULTS: The analytic sample included 1547 adults who reported past 30-day tobacco use (mean age 42.9 years, 62.8% female, 85.4% White, 48.5% income of less than $50 000). Over one-quarter (26.1%) reported dual-vaping in the past 30 days. Identifying as male (p = .002) and self-rated anxiety (p = .043) were associated with a higher odds of dual-vaping. CONCLUSIONS: Our findings show that a sizable proportion of a sample of New England adults who have used tobacco in the past 30 days are dual-vaping nicotine and cannabis. Adequate survey measures for assessing the vaping of multiple substances can help in better screening and characterization of health behaviors around dual-use. IMPLICATIONS: This study addresses a key gap in adequate survey measures for assessing vaping of multiple substances. We found that among adults with past 30-day tobacco use, dual-vaping was prevalent and associated with different correlates, such as self-reported anxiety and education level, compared to sole-vaping of nicotine or cannabis. Our findings may help in characterizing and targeting future population-level surveillance and intervention efforts for multiple substance use behaviors.

Exploring the Influence of E-cigarette Ad Features on Perceived Product Appeal and Use Interest Among Young Adults of Varying Tobacco-Use Behaviors.

INTRODUCTION: Exposure to certain features in commercial e-cigarette ads may influence e-cigarette use perceptions. This study explored the reactions toward common features in e-cigarette ads among young adults of various tobacco-use behaviors. AIMS AND METHODS: We used data from in-depth interviews with U.S. young adults (ages 18-29) who do not use tobacco (n = 26) and who currently smoke cigarettes (n = 26). Participants viewed 30 print e-cigarette ads that included multiple features (eg, fruit flavors, price promotions, smoker-targeted messages) before discussing their perceived influence of memorable ad features. We used reflective thematic analysis to analyze interview data. RESULTS: Participants from both groups generally noticed fruit and multiple flavors displayed in the ads, which were seen as appealing and were reported to generate product-use interest because of bright colors, sensory appeal, and a variety of flavor options. Participants who smoke perceived price promotions and positive experience testimonials to be appealing, and some reported this generated use interest. Participants from both groups perceived smoker-targeted messages to be unconvincing, and reported this dampened ad and product appeal and use interest. Participants who do not use tobacco perceived nicotine warnings to be unappealing, resulting in reduced perceived appeal of other attractive features (eg, fruit flavors) appearing in the same ads. CONCLUSIONS: Marketing features appearing in e-cigarette ads may be perceived by young adults of various tobacco-use behaviors in both similar and different ways. Communication and policy strategies that account for these differential perceptions towards various marketing features are needed to reduce the negative impact of e-cigarette marketing. IMPLICATIONS: This study revealed evidence related to young adults' reactions to and perceived influence of commonly used marketing features (eg, fruit flavors, nicotine warnings, price promotions, smoker-targeted messages) in commercial e-cigarette ads. The results highlight the similar and differential perceived appeal and use interest of e-cigarette products promoted with various marketing features among young adults of different tobacco-use behaviors. The results have implications for informing the design of communication strategies and policies related to e-cigarette marketing aimed at promoting complete product switching among young adults who smoke while simultaneously deterring e-cigarette use interest among those who do not use tobacco.

Key Informants' Perceptions of Health Equity and Racial Justice Impacts of the 2019 Massachusetts An Act Modernizing Tobacco Control.

INTRODUCTION: The Massachusetts legislature passed An Act Modernizing Tobacco Control in November 2019 to restrict retail sales of flavored commercially manufactured tobacco products including menthol products, increase penalties for violating the law's provisions, and provide health insurance coverage for tobacco treatment. AIMS AND METHODS: This study explores key informants' perceptions of intended and unintended impacts of implementation of the 2019 Massachusetts statewide law through a health equity and racial justice lens. We conducted in-depth interviews with 25 key informants from three key informant groups (public health officials and advocates, clinicians, and school staff) between March 2021 and April 2022. Using deductive codes on unintended impacts of the implementation of the law's policies, we conducted a focused analysis to identify impacts that were perceived and observed by informants from different key informant groups. RESULTS: Perceived or observed impacts of the law were identified across multiple levels by key informants and included concerns related to three broad themes: 1) intended impacts on health equity and racial justice, 2) ongoing availability of restricted products undermining the intended impact of the law, and 3) inequitable targeting by the policies and enforcement among communities of color. CONCLUSIONS: Future evaluation is needed to assess the intended and unintended impacts of implementation of the Massachusetts law to maximize the potential of the policies to reduce tobacco-related health disparities. We discuss implications and recommendations for achieving a national policy and equitable enforcement of flavored tobacco sales restrictions. IMPLICATIONS: This qualitative study among 25 key informants including public health and tobacco control advocates, clinicians, and school staff obtained perspectives of intended and unintended health equity and racial justice impacts of the 2019 Massachusetts An Act Modernizing Tobacco Control. Findings and recommendations from this study can inform monitoring efforts to assess the law's impacts in Massachusetts and the adoption of similar flavored tobacco sales restrictions and other tobacco control policies in other states to maximize the health equity benefits and minimize unintended impacts.

Perspectives of Sexual and Gender Minority Youth on Anti-Vaping Messages in Social Media.

INTRODUCTION: Sexual and gender minority (SGM) youth have higher rates of nicotine vaping than other youth in the United States. While social media can be effective in reaching youth and discouraging vaping, informed cultural tailoring is necessary to ensure effective messaging to SGM youth. This study aimed to understand SGM youth perspectives on anti-vaping social media messages and tailoring approaches. METHODS: In-depth, qualitative videoconference interviews were conducted from February to July 2022 with 34 SGM youth recruited in the United States via social media ads. The interview guide addressed participants' beliefs about vaping, the context of vaping, perspectives on tailoring messages, and responses to examples of social media anti-vaping messages. Coding and thematic analysis followed a team-based approach. RESULTS: SGM youth perspectives fell into four categories - representation and diversity, facts and evidence, empowering messages, and source credibility. Participants stressed the importance of accurate, genuine representation of SGM youth in messages, but also noted that more overt representation may be seen as tokenizing. Participants recommended partnering with known LGBTQ+ influencers who can promote or share anti-vaping messages on social media platforms. They also recommended using culturally tailored language, including statistics specific to SGM youth, and invoking themes of empowerment to improve the relevance, reach, and effectiveness of anti-vaping campaigns. CONCLUSIONS: Findings can inform future efforts to develop anti-vaping messages for SGM youth with effective reach through social media. Nuanced perspectives on SGM representation in messages suggest a careful approach to tailoring. Concerns around inauthenticity may be minimized by ensuring SGM youth are included in message development and dissemination. IMPLICATIONS: This study describes the importance of being attentive to the tailoring preferences among the current generation of sexual and gender minority youth. Findings will inform social media-based messaging strategies that discourage nicotine vaping tailored for SGM youth in health campaign material design and evaluation, ensuring that tailored messages are designed in ways that avoid unintended consequences. The study also describes methods for effectively engaging SGM youth in research to improve the relevance of health education materials for this population and increase reach, which in turn can lead to reduction in vaping practices among SGM youth.

Trust in federal COVID-19 vaccine oversight and parents' willingness to vaccinate their children against COVID-19: a cross-sectional study.

BACKGROUND: Over half of the youth population in the United States, aged 6 months to 17 years, have not received the Coronavirus Disease 2019 (COVID-19) vaccine. Given parents' central role in vaccinating their children, we examined associations between parents' trust of the federal oversight of COVID-19 vaccine safety and their willingness to vaccinate their children against COVID-19. METHODS: This cross-sectional study included 975 parents of minor children residing in Philadelphia who completed the online survey between September 2021 and February 2022. Trust was measured using a four-point Likert scale ranging from 'do not trust' to 'fully trust' for two variables: (1) trust in federal oversight of COVID-19 vaccine safety for children and (2) trust in federal oversight of COVID-19 vaccine safety for the general public. A multiple logistic regression evaluated associations between trust and parents' willingness to vaccinate their children, which was measured on a five-point Likert scale ranging from 'strongly disagree' to 'strongly agree.' The analysis was adjusted for race/ethnicity, age, sexual orientation, gender, education, insurance, and parents' vaccination status. RESULTS: Analyses included 975 parents whose children had not previously been vaccinated against COVID-19 (mean age 36.79, standard deviation 6.4; 42.1% racial/ethnic minorities; 93.2% heterosexual; and 73.7% with a college degree). Greater trust regarding federal oversight of COVID-19 vaccine safety for children [adjusted odds ratio (aOR) = 1.52, 95% confidence interval (CI): 1.13-2.04] and for the public (aOR = 1.58, 95% CI: 1.17-2.14) were each associated with increased willingness to have their child vaccinated against COVID-19. Unvaccinated parents had decreased willingness compared to parents who had received at least one dose of the vaccine (aOR = 0.14, 95% CI: 0.04-0.41). College-graduate parents exhibited increased willingness compared to those without a college degree (aOR = 2.07, 95% CI: 1.52-2.81). Non-heterosexual parents showed increased willingness compared to heterosexual parents (aOR = 2.30, 95% CI: 1.20-4.76). CONCLUSIONS: Trust in federal COVID-19 vaccine oversight was associated with parental willingness to vaccinate their children against COVID-19 among parents whose children have not yet been vaccinated. Identifying and addressing causes of mistrust are crucial next steps to promote child vaccination. Intervention efforts to address trust gaps should remain a public health priority.

The Relationship Between News Coverage of COVID-19 Misinformation and Online Search Behavior.

The spread of health misinformation poses a threat to public health as it can influence individuals' health beliefs and, potentially, behaviors, and their support for public health policies. The mainstream news media have the potential to inadvertently increase the salience of misinformation through their reporting. This study explores the agenda-setting effects of mainstream news media coverage on public salience of public health misinformation during the COVID-19 pandemic. We analyzed the association between news media coverage and public salience - as measured by Google Trends relative search volume - of three different pieces of COVID-19 misinformation: (1) hydroxychloroquine is a safe and effective treatment for COVID-19; (2) the COVID-19 vaccines cause infertility; and (3) ivermectin is a safe and effective treatment for COVID-19. We plotted news coverage of each piece of misinformation against Google Trends relative search volume over time. Autoregressive integrated moving average (ARIMA) models were used to account for autocorrelation and analyze the relationship between the two time series. News media coverage volume was a significant predictor of same-day relative search volume for hydroxychloroquine and ivermectin. The relationship between news media coverage and searches for COVID-19 vaccines and infertility was not significant. These findings indicate mainstream news media coverage may contribute to the public salience of misinformation. Mainstream media outlets should contextualize their reporting on misinformation with verification from scientific consensus.

Youth Participatory Action Communication Research: A Model for Developing Youth-Driven Health Campaigns.

Youth offer valuable insight on health communication needs and solutions in their communities. We propose youth participatory action communication research (YPACR) as a model for health campaign development that engages youth perspectives in applying systematic theory-informed communication research to addressing youth-identified health priorities. YPACR informed a series of paid high school internship programs in West Philadelphia, in which youth interns identified mental health help-seeking communication as a need among peers. In Phase 1, guided by the reasoned action approach and Hornik & Woolf method, youth interns conducted a survey measuring behavioral beliefs, normative beliefs, and control beliefs associated with mental health help-seeking, as well as trusted sources of mental health information, among local high school students. Survey results suggested control (self-efficacy) was an important message target and peers were trusted mental health information sources. In Phase 2, youth interns developed TikTok-style messages focused on strengthening control beliefs and promoting a youth-selected mental health support resource. Youth interns distributed an online survey experiment to test whether youth-created messages shown alongside resource information increased help-seeking self-efficacy compared to an information-only control. The YPACR framework contributed to youth-relevant campaign goals, study measurements, recruitment approaches, data interpretation, and message design. We discuss the benefits and challenges of this youth-driven health campaign development model and recommendations for future research.

"We're always an afterthought"- Designing tobacco control campaigns for dissemination with and to LGBTQ +-serving community organizations: a thematic analysis.

PURPOSE: Evidence-based health communication campaigns can support tobacco control and address tobacco-related inequities among lesbian, gay, bisexual, transgender, and queer (LGBTQ +) populations. Community organizations focused on LGBTQ + health (e.g., nonprofits, community centers, and community health centers) can be prime channels for delivering evidence-based health communication campaigns. However, it is unclear how to balance the goals of a) designing campaigns to support broad adoption/uptake and b) adaptation addressing the needs of diverse communities and contexts. As part of an effort to support "designing for dissemination," we explored the key challenges and opportunities staff and leaders of LGBTQ + -serving community organizations encounter when adopting or adapting evidence-based health communication campaigns. METHODS: A team of researchers and advisory committee members conducted this study, many of whom have lived, research, and/or practice experience with LGBTQ + health. We interviewed 22 staff members and leaders of community organizations serving LGBTQ + populations in the US in early 2021. We used a team-based, reflexive thematic analysis approach. RESULTS: The findings highlight the challenges of attempting to use health communication campaigns misaligned with the assets and needs of organizations and community members. The three major themes identified were as follows: (1) available evidence-based health communication campaigns typically do not sufficiently center LGBTQ + communities, (2) negotiation regarding campaign utilization places additional burden on practitioners who have to act as "gatekeepers," and (3) processes of using health communication campaigns often conflict with organizational efforts to engage community members in adoption and adaptation activities. CONCLUSIONS: We offer a set of considerations to support collaborative design and dissemination of health communication campaigns to organizations serving LGBTQ + communities: (1) develop campaigns with and for LGBTQ + populations, (2) attend to the broader structural forces impacting campaign recipients, (3) support in-house testing and adaptations, and (4) increase access to granular data for community organizations.

Tobacco Cessation and Prevention Interventions for Sexual and/or Gender Minority-Identified People and the Theories That Underpin Them: A Scoping Review.

INTRODUCTION: This scoping review takes stock of the social and behavior change theories that have underpinned tobacco interventions tailored to sexual and/or gender minority (SGM) people and reflects on the need to target contextually based drivers of SGM tobacco use inequities. AIMS AND METHODS: Data sources were Medline (Ovid), Scopus, PubMed, and Google Scholar (January 01, 1946 to October 27, 2022). Peer-reviewed publications in English from anywhere in the world describing SGM-tailored tobacco cessation and/or prevention interventions were independently identified by a librarian and screened by the first and third authors. Three hundred and sixty-seven articles were extracted; an additional two were found by hand searching. A total of 369 articles were assessed for eligibility. Exclusion criteria were: Not an intervention, review article, not SGM-tailored, or tobacco-focused. We documented the intervention name, intervention components, theoretical frameworks cited in reference to intervention design and/or implementation, and evaluation outcomes. All authors provided input on theoretical framework categorization. RESULTS: We identified 22 publications corresponding to 15 unique interventions. Individual-level behavior change theories (ie, those focusing on within-person behavior change processes) were the most prominent. Among these, the Transtheoretical Model was the most frequently utilized, while Social Inoculation Theory, Theory of Reasoned Action, and Theory of Psychological Reactance were also employed. A minority of interventions referenced frameworks that more explicitly engaged with SGM people's social contexts, namely, Theory of Diffusion of Innovations and Minority Stress Model. CONCLUSIONS: Future SGM-tailored tobacco interventions should leverage both the strengths of individual-level behavior change theories and those of frameworks that understand tobacco use inequities as indivisible from place, context, and policy. IMPLICATIONS: This scoping review describes the theoretical underpinnings of sexual and/or gender minority (SGM)-tailored tobacco interventions published in the peer-review literature in English. It reflects on the need for greater utilization of social and behavior change theoretical frameworks that can engage with unique drivers of SGM tobacco use and barriers to cessation.

Incorporating Intersectionality as a Framework for Equity-Minded Tobacco Control Research: A Call for Collective Action Toward a Paradigm Shift.

INTRODUCTION: To eliminate tobacco-related disparities, tobacco control research would benefit from a paradigm shift. Intersectionality, a framework pioneered by Kimberlé Crenshaw in late 1980s, has the potential to improve our understanding of why and how certain social groups are disproportionately harmed by commercial tobacco use, and improve our ability to address persistent tobacco-related health disparities. AIMS AND METHODS: In this commentary, we outline the rationale and recommendations for incorporating intersectionality into equity-minded tobacco control research. These recommendations arose from intersectionality webinars organized by the Health Disparities (now Health Equity) Network of the Society for Research on Nicotine & Tobacco (SRNT) in 2019 and 2020. RESULTS: Specifically, we propose that eliminating tobacco-related disparities through intersectionality-informed research requires a multilevel, multipronged approach. We summarize priority actions for the tobacco control research field to achieve health equity through the intersectionality framework including acknowledging that structural factors, racism and power dynamics shape lived experiences, integrating critical theoretical frameworks and intersectionality scholarship into research questions, and embracing collaborative community-based approaches at every level of the research process. CONCLUSIONS: Through these actions, our field can take concrete steps to fundamentally improve our approach to conducting research to achieve health equity. IMPLICATIONS: Intersectionality is a valuable tool to align our field with our pursuit of health equity. The recommendations aim to improve methods of equity-focused tobacco control, prompt ongoing dialogue on the utility of this tool, and shift paradigms in how the research process is conducted at every level among stakeholders, including researchers, journal editors and reviewers, funders, practitioners, and policy makers.

Youth tobacco use before and after flavoured tobacco sales restrictions in Oakland, California and San Francisco, California.

The tobacco industry has used recent findings from the Youth Risk Behavior Surveillance System Survey (YRBSS) to claim that a sales restriction on flavoured tobacco products might increase youth combustible cigarette use. In this special communication, we examined YRBSS data and reached the opposite conclusion. We observed the patterns in youth cigarette smoking in Oakland, California following its 2017 convenience store flavoured tobacco sales restriction. We also found that 2019 YRBSS data from San Francisco, California cannot be used to evaluate the effect of the sales restriction on all flavoured tobacco products in San Francisco as the YRBSS data for this city were collected prior to enforcement of the sales restriction. For future studies, we suggest triangulating with corroborating sales, behavioural and qualitative data over time to assess the effects of tobacco control policies on youth tobacco use. We recommend that policy enactment and enforcement dates, as well as the exact data collection periods for population health surveys, be published to facilitate more rigorous policy evaluation.

IQOS print magazine advertising characteristics and reach before and after FDA authorisation as a modified risk tobacco product.

INTRODUCTION: IQOS is a heated tobacco product that was authorised as a modified risk tobacco product (MRTP) in July 2020. While it was removed from the US market in 2021 for legal reasons, as the first tobacco product to receive an 'exposure modification' MRTP order, surveillance of IQOS marketing is needed to inform regulation and policy for future MRTPs. The purpose of this study is to expand the current research on IQOS advertising in the USA by examining content and readership characteristics of IQOS ads in print magazines before and after US Food and Drug Administration MRTP authorisation. METHODS: We merged content analysis data with Kantar Media data on magazine placement and expenditures. Magazine readership data were obtained from MRI-Simmons. We compared data from pre-MRTP authorisation with data post-MRTP authorisation. This study was conducted in 2021. RESULTS: There was one unique ad and there were 13 observations pre-MRTP, and eight unique ads and 132 observations post-MRTP. Compared with pre-MRTP ads, more post-MRTP ads featured Marlboro HeatSticks, including Amber HeatSticks, and featured people. All ads contained a warning label-most warning labels were cigarette specific. IQOS ads were featured in magazines that are especially popular among women. CONCLUSIONS: After receiving MRTP authorisation, IQOS increased ad expenditures in print magazines with a readership comprised of primarily women. If IQOS returns to the US market, it will be important for tobacco control to monitor their advertisement content, placement, and expenditures.

Effects of cigarette package colors and warning labels on marlboro smokers' risk beliefs, product appraisals, and smoking behavior: a randomized trial.

OBJECTIVE: Plain packaging and graphic warning labels are two regulatory strategies that may impact cigarette risk beliefs and reduce consumption, but data are needed to better understand how smokers respond to such regulations. METHODS: Adult, daily, Marlboro non-menthol smokers (Red [n = 141] or Gold [n = 43]) completed a mixed factorial randomized trial. Participants smoked their usual cigarettes during baseline (5-days) and were randomized to receive cigarette packs with a warning label manipulation (graphic vs. text-only). Within each warning label condition, participants completed three within-subjects pack color manipulations (red, gold, plain), each lasting 15 days. Participants were blinded to the fact that all packs contained their usual cigarettes. Mixed-effects models examined between- and within-subject differences on risk beliefs, product perceptions, and smoking behavior. RESULTS: Warning type and package color did not impact cigarette consumption or subjective ratings. However, use increased in all conditions (2.59-3.59 cigarettes per day) relative to baseline. While smokers largely held correct risk beliefs at baseline (Mean = 6.02, SE = 0.17, Range:0-8), the cumulative number of incorrect or uncertain cigarette risk beliefs increased from baseline in all pack color manipulations in the text (IRR range = 1.70-2.16) and graphic (IRR range = 1.31-1.70) warning conditions. Across all pack color periods, those in the graphic (vs. text) warning condition had reduced odds of reporting their study cigarettes as 'safer' than regular cigarettes (OR range = 0.22-0.32). CONCLUSIONS: Pack color modification may increase uncertainty about several key cigarette risk beliefs, though graphic warnings may attenuate these effects. Regulatory agencies could consider supporting policy changes with information campaigns to maximize public knowledge. TRIAL REGISTRATION: November 25, 2014; Registration number: NCT02301351.

Effects of reduced nicotine content cigarette advertising with warning labels and social media features on product perceptions among young adults.

This study sought to understand reactions to very low nicotine (VLN) cigarette advertising compared with conventional cigarette advertising with consideration of warning labels and social media context. The online experimental study recruited young adult cigarette smokers and nonsmokers (N = 1,608). Participants completed a discrete choice task with a 2 × 2 × 3 mixed design: brand, (VLN, Marlboro), context (Ad only, Ad on social media), and warning (Text-only, Well-known risk pictorial, or Lesser-known risk pictorial). Participants made choices about attention, appeal, harm, buying, and quitting intentions. Social media context increased attention and appeal. A well-known risk pictorial warning outperformed a text-only warning. Smokers had increased odds of quit intentions for VLN ads, yet nonsmokers had increased intentions to buy cigarettes on social media with a text-only warning. Results indicate differences in how young adults react to cigarette ads on social media, especially with the warnings they portray.

3D hanging spheroid plate for high-throughput CAR T cell cytotoxicity assay.

BACKGROUND: Most high-throughput screening (HTS) systems studying the cytotoxic effect of chimeric antigen receptor (CAR) T cells on tumor cells rely on two-dimensional cell culture that does not recapitulate the tumor microenvironment (TME). Tumor spheroids, however, can recapitulate the TME and have been used for cytotoxicity assays of CAR T cells. But a major obstacle to the use of tumor spheroids for cytotoxicity assays is the difficulty in separating unbound CAR T and dead tumor cells from spheroids. Here, we present a three-dimensional hanging spheroid plate (3DHSP), which facilitates the formation of spheroids and the separation of unbound and dead cells from spheroids during cytotoxicity assays. RESULTS: The 3DHSP is a 24-well plate, with each well composed of a hanging dripper, spheroid wells, and waste wells. In the dripper, a tumor spheroid was formed and mixed with CAR T cells. In the 3DHSP, droplets containing the spheroids were deposited into the spheroid separation well, where unbound and dead T and tumor cells were separated from the spheroid through a gap into the waste well by tilting the 3DHSP by more than 20°. Human epidermal growth factor receptor 2 (HER2)-positive tumor cells (BT474 and SKOV3) formed spheroids of approximately 300-350 µm in diameter after 2 days in the 3DHSP. The cytotoxic effects of T cells engineered to express CAR recognizing HER2 (HER2-CAR T cells) on these spheroids were directly measured by optical imaging, without the use of live/dead fluorescent staining of the cells. Our results suggest that the 3DHSP could be incorporated into a HTS system to screen for CARs that enable T cells to kill spheroids formed from a specific tumor type with high efficacy or for spheroids consisting of tumor types that can be killed efficiently by T cells bearing a specific CAR. CONCLUSIONS: The results suggest that the 3DHSP could be incorporated into a HTS system for the cytotoxic effects of CAR T cells on tumor spheroids.

Presence of Content Appealing to Youth on Cannabis-Infused Edibles Packaging.

BACKGROUND: There is a lack of consistent regulation of cannabis edibles packaging to restrict youth-appealing content in the United States. OBJECTIVE: To describe content appealing to youth on U.S. cannabis-infused edibles packaging. METHODS: We analyzed 256 photos of cannabis-infused edibles packaging collected from U.S. adults from 25 states, District of Columbia, and Puerto Rico between May 2020 to August 2021. We coded the presence of product knockoffs, human and non-human creatures, images indicating flavor, text indicating flavor, and the number of colors. We compared these codes across states' legalization status (medical and non-medical cannabis, medical cannabis only, or limited cannabis legalization). RESULTS: Overall, 15% of packages resembled product knockoffs, 23% contained human/non-human creatures, 35% contained flavor images, 91% contained flavor text, and median number of colors was 5 (range from 1 to 10+). Packages purchased in states with medical and non-medical cannabis, medical cannabis only, or limited cannabis legalization differed significantly on product knockoffs (11%, 26%, 38%, p = 0.007), human/non-human creatures (19%, 33%, 63%, p = 0.002), flavor text (93%, 81%, 100%, p = 0.046), and number of colors (median of 5, 5, and 10, p = 0.022). CONCLUSIONS: Existing laws have not adequately limited content appealing to youth on U.S. cannabis-infused edibles packaging. Robust and consistent regulations in the U.S. are needed to ensure that the packaging of such products does not contain content that appeal to youth and lead to initiation or inadvertent ingestion.

Trust, influence, and community: Why pharmacists and pharmacies are central for addressing vaccine hesitancy.

In 2019, the World Health Organization listed vaccine hesitancy, defined as the reluctance or refusal to vaccinate against preventable infectious diseases, as one of the top ten threats to global health. To address hesitancy, we must focus our attention on building vaccine confidence, trust in the vaccine itself, in providers who administer vaccines, and in the process that leads to vaccine licensure and the recommended vaccination schedule. Building vaccine confidence, particularly in communities that have higher levels of distrust of vaccines and low vaccination coverage rates, is a critical public health priority, particularly in the current climate as the United States and the global public health community grapple with the coronavirus disease 2019 pandemic. In this commentary, we focus on the central role that pharmacists play in promoting the health and wellness of the local communities in which they are embedded, how they are one of the most trusted sources for their communities when it comes to health information and care, and their unique position in making a profound contribution to building vaccine confidence. We propose to arm all health professionals with a tool, the ASPIRE framework, which serves as a series of actionable steps to facilitate conversations with communities. This framework is intended to assist pharmacists in communicating with community members who may have concerns about vaccines by sharing trustworthy health information about vaccines to increase vaccine adoption. We conclude that it is insufficient to merely relay accurate health information about vaccines to the public and expect dramatic increases to vaccination rates. Accurate health information needs to be conveyed by trusted sources. Open engagement and dialogue layered on top of fundamental facts and messages are central to building confidence. Pharmacists and other providers can use tools such as ASPIRE to guide their conversations with community members to increase vaccine adoption.

Differences in Tobacco Product Use by Sexual Orientation and Violence Factors Among United States Youth.

OBJECTIVE: To assess differences in the relationship between violence factor exposure and tobacco product pattern use (exclusive and poly), we hypothesized that compared with heterosexuals, sexual minority youth would be more likely to report exclusive-tobacco and poly-tobacco use patterns, and controlling for violence factors would attenuate these associations. STUDY DESIGN: Data from 27 513 US high-school youth were analyzed from the Centers for Disease Control and Prevention's Youth Risk Factor Surveillance System from 2015 and 2017. We fit sex-stratified, weighted, adjusted log-Poisson models to compare past 30-day exclusive combustible, exclusive e-cigarette, and poly-tobacco use in across sexual orientation. Then, models were adjusted for past-year experiences of physical fighting, bullying, attempting suicide, and physical and sexual dating violence. RESULTS: Compared with heterosexual girls with other-sex partners, sexual minority girls were more likely to use exclusive combustible, exclusive e-cigarette, or poly-tobacco products. When adjusting for violence factors, most tobacco use associations were partially attenuated for all sexual minority girls, and completely attenuated for exclusive e-cigarette use among all sexual minority girls. CONCLUSIONS: Sexual minority girls have greater exclusive- and poly-tobacco use compared with heterosexual girls. Tobacco interventions for sexual minority youth should address the risks of poly-tobacco use as well as violence-based risk factors.
