RESUMO

INTRODUCTION: Cigarillos are the second most used tobacco product among younger populations. The highest prevalence of use of cigars is among sexual and gender minority (SGM) women. Policy interventions like flavor bans and the availability of alternative tobacco products may have a disparate effect. METHODS: The current study utilized an online store analog, The Experimental Tobacco Marketplace (ETM), to investigate the effects of cigarillo and ENDS flavor bans on tobacco product purchasing. SGM (n=72) and cisgender heterosexual (Cis-Het; n =46) women viewed conditions in which cigarillo flavors were available or unavailable and ENDS flavors available or unavailable and the interaction between the two. Mixed models were conducted on each dependent variable with condition, price, and SGM identity as predictors and nicotine dependence, annual income, and race/ethnicity as covariates. Simple linear regressions were performed to determine the substitution profile for each tobacco product. Condition showed no effect. RESULTS: We found a main effect of price on cigarillo purchasing and a main effect of SGM identity in which SGM women purchased more ENDS than CisHet women. A complementary association between cigarillos and ENDS in which ENDS purchasing decreased as cigarillo purchasing decreased was found. This association was irrespective of flavor ban conditions and among SGM women only. CONCLUSIONS: These results suggest that flavor availability of cigarillos and ENDS may not influence women who use cigarillos to move to another tobacco product and that women SGM cigarillo users are not likely to substitute their cigarillo smoking behavior with ENDS. IMPLICATIONS: The results of this study suggest that SGM women are not likely to quit using cigarillos if flavors are removed from the market and instead will use unflavored products. Substituting their cigarillo use with ENDS does not appear likely given the complementary relation found between cigarillos and ENDS. The substitution patterns found for cigarettes and ENDS are not found for cigarillos and ENDS among young adult women who use cigarillos, further demonstrating the need for research on the conditions in which people who use cigarillos will decrease consumption or switch to a potentially less harmful product.

RESUMO

Veganism is a practice that promotes abstinence from all animal-derived products or foods. While veganism commonly refers to adopting a vegan diet, the term "veganism" also encompasses broader lifestyle practices. As veganism grows in popularity, patients often turn to their der-matologists for guidance regarding the identification of vegan ingredients in personal care and hair care products.1 Additionally, several over-the-counter (OTC) and prescription medications recommended in the management of dermatologic conditions are often questioned about their applicability to veganism. We discuss the relevance of vegan diets to dermatologic clinical practice, address common questions relevant to patients, and offer guidance on how to identify vegan products.

RESUMO

BACKGROUND: E-cigarette advertising, which often includes various features, may prompt e-cigarette use and product switching. This study examined the associations between noticing e-cigarette ad features and perceived product appeal and interest in completely switching from cigarettes to advertised e-cigarettes among young adult dual users of both products. METHODS: We analyzed data from an online heatmap experiment among young adult dual users defined as established cigarette smokers who currently used e-cigarettes (ages 18-34 years; n = 1,821). Participants viewed 12 e-cigarette ads, clicked on ad features (e.g., fruit flavors, nicotine warnings, price promotions, smoker-targeted claims) that attracted their attention (defined as "noticing"), and answered questions about e-cigarette product appeal and interest in completely switching from cigarettes to the e-cigarettes shown. We examined within-person associations between noticing specific ad features and outcomes, controlling for demographic and tobacco use-related characteristics. RESULTS: Noticing fruit flavors (AOR = 1.67 and 1.28) and fruit images (AOR = 1.53 and 1.21) was positively associated with having any e-cigarette product appeal and switching interest. Noticing price promotions (AOR = 1.23) was positively associated with product appeal. In contrast, noticing nicotine warnings (AOR = 0.74 and 0.86), smoker-targeted claims (AOR = 0.78 and 0.89), and tobacco flavors (AOR = 0.92 and 0.90) was negatively associated with product appeal and switching interest. CONCLUSIONS: Noticing certain e-cigarette ad features (e.g., fruit flavors and nicotine warnings) may be associated with product appeal and/or switching interest among young adult dual users. More research is needed to assess the influence of e-cigarette ad features that promote product switching interests among cigarette smokers while discourage interests among tobacco-naïve individuals.

RESUMO

Despite interest in quitting vaping among young adults (YAs), little is known about characteristics of e-cigarette (EC) users seeking treatment. In this study, YAs aged 18-24 living in the United States interested in vaping cessation treatment were recruited to complete an online survey regarding demographics and EC use. Primary eligibility criteria were EC use on at least 20 days per month (no other tobacco use), and interest in quitting in the next month. We report descriptive statistics for those who did and did not complete a mandatory coaching call (n = 981). In this sample, most EC users reported high nicotine dependence, a history of unsuccessful quit attempts (including 29.4% with previous NRT use), along with stress, anxiety, and depression. There were few meaningful differences in demographics, EC use behaviors, or behavioral health factors between those who engaged with a phone coaching call (fully enrolled in study; n = 508), and those who did not (n = 473). YAs demonstrated interest in vaping cessation support, but there were no clear characteristics for the half who did not complete a coaching call. Vaping cessation program designers should consider tailoring for the self-reported behavioral health concerns present in this population.

RESUMO

INTRODUCTION: Young adults who are sexual and gender minorities (SGM) are at the highest risk for tobacco initiation in young adulthood. Minority stress theory suggests that sexual orientation and gender identity (SOGI)-based discrimination may contribute to nicotine and tobacco use disparities. Our study aimed to quantify the association between SOGI-based distal minority stressors and current tobacco use among SGM young adults living in the United States (US). METHODS: Eligible participants-including young adults (aged 18-35 years old), who identified as SGM, and were currently residing in the US (N=1116) -were recruited via Prolific into an online survey. We applied stepwise binary regressions with backward selection to model the association between average past 30-day distal minority stress and current tobacco use (i.e., combustible cigarettes or e-cigarettes), controlling for perceived stress and sociodemographic covariates. We also tested interactions between minority stress and SGM status. Exploratory analyses assessed associations between minority stress and current tobacco use among YA, stratified by SGM subgroup. RESULTS: A 1-unit increase in experiencing minority stress in the past 30-days was associated with 1.02 greater odds of current tobacco use among SGM young adults. No difference between SGM subgroups in this association was found. Examining stratified SGM subgroups, a 1-unit increase in minority stress was associated with 1.11 greater odds of current tobacco among transgender adults only. CONCLUSION: Distal minority stress is differentially associated with current tobacco use for transgender young adults, which suggests that tobacco prevention and cessation interventions may need tailoring for subgroups. IMPLICATIONS: This study details the influence of minority stress on current tobacco use among sexual and gender minority (SGM) young adults. Findings underscore the need for targeted and tailored approaches to tobacco control, wherein SGM young adults most at-risk are engaged in cessation interventions that address minority stress as a contributing factor to tobacco use and which support their resilience. To promote health equity, tobacco control must address the contexts that engender minority stress. Assessment of policy impacts on SGM tobacco use and the effectiveness of interventions disseminated within SGM-supportive and discriminatory policy environments are important next steps.

RESUMO

INTRODUCTION: The purpose of this research was to identify how young adult sexual gender minority (SGM) women who use cigarillos may respond to cigar flavor restrictions. AIMS AND METHODS: Young adults aged 21-28 years in the United States who currently use cigarillos were recruited between October 2020 and April 2021 to participate in an online survey. Due to high prevalence of cigarillo use among individuals who identify as sexual and/or gender minority (SGM) women, their (n = 192) flavored tobacco-use behaviors and anticipated responses to cigarillo flavor restrictions were compared to cisgender heterosexual (CisHet) women (n = 110). Logistic regression was used to model cigarillo cessation and product-switching behaviors (flavored and unflavored). RESULTS: SGM women were significantly less likely to report the use of flavor at the initiation of cigarillo use (61.7% vs. 86.1%) but were no different in current flavor use compared to CisHet women, with more than 80% of all women using any flavor. SGM women were 2.36 times as likely to say they would discontinue using cigarillos if flavors were unavailable. Among those who would continue using cigarillos, SGM women were 4.53 times as likely to endorse switching to an unflavored tobacco product but had the same likelihood of saying they would switch to flavored product compared to CisHet women. CONCLUSIONS: Flavor restriction policies may not reduce the initiation of cigarillos among SGM women and may elicit differential cigarillo use and tobacco product substitution by SGM identity. Flavor restriction policies should be coupled with targeted cessation resources to address potential remaining disparities. IMPLICATIONS: SGM US women have a unique cigarillo-use trajectory. These women are more likely to initiate cigarillos without flavor and then later integrate it into their behavior. National cigar flavor restrictions are expected to have a greater impact decreasing cigarillo initiation among CisHet women and decreasing current cigarillo use among SGM women. However, for those who would continue using unflavored cigarillos, SGM women may remain at risk for nicotine dependence due to increased product substitution. SGM women should be prioritized for cessation resources to reduce tobacco-use disparities leading up to and following the implementation of cigar flavor restrictions.

RESUMO

INTRODUCTION: E-cigarette use is most prevalent among adolescents and young adults - and there are often misperceptions about product risk. The purpose of this study was to determine what nicotine information is provided on e-cigarette brand websites. METHODS: Based on national and local surveys, we identified 44 e-cigarette brands commonly used in the US by adolescents and young adults. For each of these brands, their associated websites were analyzed for disclosed nicotine information. Specifically, for each brand's website, we coded whether there was information on nicotine concentration (recorded if a numerical value was provided such as '5% nicotine'), nicotine form (free-base, nicotine salts, or not stated), and nicotine type (tobacco-derived, synthetically derived, or not stated). Coding allowed for both lay (e.g. 'nic salts') as well as scientific (e.g. 'isomers') terms. RESULTS: Of the 44 brands examined, all provided basic information on nicotine concentration (e.g. '5% nicotine'). However, 23% of brands did not disclose information on nicotine form (i.e. nicotine salt vs free-base), and 66% of brands did not disclose information on nicotine type (i.e. synthetic vs tobacco-derived). CONCLUSIONS: Overall, these results suggest that the e-cigarette industry is not fully informing its consumers about the nicotine in their products. Given that nicotine form and type have implications for e-cigarette addiction potential, these findings highlight a public health concern. There is a need for more comprehensive national regulations for mandating product constituents and emissions disclosures.

RESUMO

Health warning labels have been found to increase awareness of the harmful effects of tobacco products. An eye tracking study was conducted to determine the optimal placement and type of a health warning label on tobacco waterpipes. Participants viewed images that contained one of (1) four waterpipes, (2) three different types of warning labels, (3) placed in three locations. Typically, statistical analysis of eye tracking data is conducted based on summary statistics such as total dwell time, duration score, and number of visits to an area of interest. However, these summary statistics fail to capture the complete variability in a participant's eye movement. Instead, we propose to estimate heat maps defined on the entire image domain using the raw two-dimensional coordinates of eye movement via kernel density estimation. For statistical analysis of heat maps, we adopt the Fisher-Rao Riemannian geometric framework, which enables computationally efficient comparisons of heat maps, statistical summarization and exploration of variability in a sample of heat maps, and metric-based hierarchical clustering. We apply this framework to eye tracking data from the tobacco waterpipe study and comment on the results in the context of the optimal placement and type of health warning labels on tobacco waterpipes.

RESUMO

The clinical value of serial routine bone marrow aspirates (rBMAs) in the first year after allogeneic hematopoietic cell transplantation (alloHCT) to detect or predict relapse of acute leukemia (AL) and myelodysplastic syndrome (MDS) in pediatric and young adult patients is unclear. The purpose of this analysis was to determine if assessment of minimal residual disease (MRD) by multiparameter flow cytometry (MFC, MFC-MRD) or donor chimerism (DC) in rBMAs or serial complete blood counts (CBCs) done in the year after alloHCT predicted relapse of AL or MDS in pediatric and young adult patients. We completed a retrospective analysis of patients with AL or MDS who had rBMAs performed after alloHCT between January 2012 and June 2018. Bone marrow (BM) was evaluated at approximately 3, 6, and 12 months for disease recurrence by morphology, MFC-MRD, and percent DC by short tandem repeat molecular testing. CBCs were performed at every clinic visit. The main outcome of interest was an assessment of whether MFC-MRD or DC in rBMAs or serial CBCs done in the year after alloHCT predicted relapse in AL or MDS pediatric and young adult patients. A total of 121 recipients with a median age of 13 years (range 1 to 32) were included: 108 with AL and, 13 with MDS. A total of 423 rBMAs (median 3; 0 to 13) were performed. Relapse at 2 years was 23% (95% CI: 16% to 31%) and at 5 years 25% (95% CI: 18% to 33%). One hundred fifty-four of 157 (98%) rBMAs evaluated for MRD by MFC were negative and did not preclude subsequent relapse. Additionally, low DC (<95%) did not predict relapse and high DC (≥95%) did not preclude relapse. For patients alive without relapse at 1 year, BM DC (P = .74) and peripheral T-cell DC (P = .93) did not predict relapse. Six patients with low-level T-cell and/or BM DC had a total of 8 to 20 BM evaluations, none of these patients relapsed. However, CBC results were informative for relapse; 28 of 31 (90%) relapse patients presented with an abnormal CBC with peripheral blood (PB) blasts (16 patients), cytopenias (9 patients), or extramedullary disease (EMD, 3 patients). Two patients with BM blasts >5% on rBMA had circulating blasts within 5 weeks of rBMA. Neutropenia (ANC <1.5 K/mcl) at 1 year was predictive of relapse (P = .01). Neutropenia and thrombocytopenia (<160 K/mcl) were predictive of disease-free survival (DFS) with inferior DFS for ANC <1.5 K/mcl, P = .001, or platelet count <160 K/mcl (P = .04). These results demonstrate rBMAs after alloHCT assessed for MRD by MFC and/or for level of DC are poor predictors for relapse in pediatric and young adult patients with AL or MDS. Relapse in these patients presents with PB blasts, cytopenias, or EMD. ANC and platelet count at 1-year were highly predictive for DFS.

RESUMO

BACKGROUND AIMS: Traditional weight-based dosing of rabbit anti-thymocyte globulin (rATG) used in allogeneic hematopoietic cell transplantation (HCT) to prevent graft-versus-host disease (GVHD) and graft rejection leads to variable exposures. High exposures induce delayed CD4+immune reconstitution (CD4+IR) and greater mortality. We sought to determine the impact of rATG exposure in children and young adults receiving various types of EX-VIVO T-cell-depleted (EX-VIVO-TCD) HCT. METHODS: Patients receiving their first EX-VIVO-TCD HCT (CliniMACS CD34+, Isolex or soybean lectin agglutination), with removal of residual T cells by E-rosette depletion (E-) between 2008 and 2018 at Memorial Sloan Kettering Cancer Center were retrospectively analyzed. rATG exposure post-HCT was estimated (AU*d/L) using a validated population pharmacokinetic model. Previously defined rATG-exposures, <30, 30-55, ≥55 AU*d/L, were related with outcomes of interest. Cox proportional hazard and cause-specific models were used for analyses. RESULTS: In total, 180 patients (median age 11 years; range 0.1-44 years) were included, malignant 124 (69%) and nonmalignant 56 (31%). Median post-HCT rATG exposure was 32 (0-104) AU*d/L. Exposure <30 AU*d/L was associated with a 3-fold greater probability of CD4+IR (P < 0.001); 2- to 4-fold lower risk of death (P = 0.002); and 3- to 4-fold lower risk of non-relapse mortality (NRM) (P = 0.02). Cumulative incidence of NRM was 8-fold lower in patients who attained CD4+IR compared with those who did not (P < 0.0001). There was no relation between rATG exposure and aGVHD (P = 0.33) or relapse (P = 0.23). Effect of rATG exposure on outcomes was similar in three EX-VIVO-TCD methods. CONCLUSIONS: Individualizing rATG dosing to target a low rATG exposure post-HCT while maintaining total cumulative exposure may better predict CD4+IR, reduce NRM and increase overall survival, independent of the EX-VIVO-TCD method.

RESUMO

BACKGROUND: Among adolescents and young adults (AYAs), "current use" of electronic cigarettes (e-cigarettes) is commonly defined as any use in the past 30 days. However, few studies have examined differences among those within this broad category. This study examined characteristics of AYAs who used e-cigarettes at a low frequency (within the last 3 months but <6 days out of the past 30 days) and those who used e-cigarettes at a high frequency (6+ days out of the past 30 days). METHODS: We conducted cross-sectional analyses among 551 Ohio AYAs (15- to 24-year-olds) who reported using an e-cigarette to vape nicotine in the past 3 months. We used descriptive statistics and logistic regression to characterize those using e-cigarettes at a low frequency and a high frequency. RESULTS: Among our sample of AYAs who reported past 3-month e-cigarette use, about half (50.8%) reported using an e-cigarette 6 or more days out of the past 30 days (ie, high frequency). In the multivariable analysis, reported nicotine dependence (Odds Ratio [OR]: 7.0, 95% CI: 4.8, 10.3) and current other tobacco product use (OR: 1.8, 95% CI: 1.1, 2.9) were associated with high-frequency e-cigarette use. CONCLUSION: Our results suggest that frequency of use is an important characteristic in understanding AYA e-cigarette use. Any use in the past 30 days may not be sensitive enough to understand dependence and tobacco-use behaviors. Further characterizing "current" e-cigarette use by frequency of use may provide meaningful information for public health professionals to better target intervention and cessation efforts to AYAs.

RESUMO

The concept of "fatherhood" in many African countries has traditionally been understood in terms of instrumental support to one's family, most notably, financial provision. However, in Sierra Leone and elsewhere, this narrow understanding of fatherhood is changing as a result of shifting demographic trends and responses to recent crises such as the Ebola pandemic and the aftermath of a civil war. Very little is understood about how male former children associated with armed forces and armed groups (CAAFAG) are navigating fatherhood and understanding their roles as fathers, particularly as many have grown up without fathers or parents themselves and experienced violence. Our study builds upon previous ethnographic research in Sierra Leone, and uses a phenomenological approach to understand 1) the meaning and importance of fatherhood to former child soldiers in Sierra Leone, 2) what fatherhood looks like normatively and ideally, with attention to norms about nurturing care as well as violence, and 3) how ideals of fatherhood may or may not be in tension with socioeconomic circumstances. We find that CAAFAG fathers in Sierra Leone are committed to providing emotional support, encouragement, and a loving upbringing in addition to striving to provide financially. CAAFAG fathers experienced the greatest tension between their ideals of fatherhood and their socio-economic circumstances in terms of financial support, such as paying school fees. In other words, fathers felt inhibited in becoming the types of fathers they hoped to be due to their experiences in a post-conflict, resource-constrained environment.
