INTRODUCTION/BACKGROUND:Secondhand exposure to e-cigarettes represents a potential population health risk given e-cigarette's prevalence and their unknown health effects, particularly among vulnerable populations such as pregnant people. OBJECTIVES/OBJECTIVE:To explore metabolomic differences between pregnant people exposed vs. not exposed to secondhand e-cigarette aeresols, to identify possible biomarkers of exposure and metabolic pathways perturbed by e-cigarettes. METHODS:Exposed participants (n = 19) from the NYU Children's Health and Environment Study were matched to unexposed participants (n = 57) at a 1:3 ratio on age, hospital of recruitment, and race/ethnicity. Early-pregnancy urine samples were analyzed via an untargeted metabolomics platform using reverse-phase liquid chromatography mass-spectrometry. Feature-exposure associations were estimated using conditional logistic regression to adjust for matching factors. A sensitivity analysis was conducted adjusting for secondhand tobacco exposure. RESULTS:Among features enriched in the exposed group were flavonoids and flavor-related compounds including homoeriodictyol and naringenin-7-O-beta-D-glucuronide, 3-acetomidocoumarin, and guaiacol pentosylglucoside; synthetic drugs such as the endocannabinoid AM1172 and the stimulant alpha-PVP; and metabolites associated with lipid metabolism, including 2,4-undecadiene-8,10-diynoic acid isobutylamide, palmitamide, glycerol trihexanoate, and tetradecyl phosphonate. Among features negatively associated with exposure were xanthines. CONCLUSION/CONCLUSIONS:This study is the first untargeted metabolomics study investigating metabolomic markers of e-cigarette exposure, including secondhand exposure, in a pregnant cohort. Despite this study's small size and exploratory nature, the results of this work suggest that flavoring components could be biomarkers for e-cigarette exposure, and that co-exposure to e-cigarettes and other drugs may be prevalent.

OBJECTIVES/OBJECTIVE:Edentulism and diabetes mellitus (DM) are frequently seen among older adults. However, the joint effect of edentulism and DM on mortality was understudied. We aim to examine the joint effect of edentulism and DM on all-cause mortality and to what extent the joint effect varies by race/ethnicity. METHODS:Analysis of US Health and Retirement Study (HRS) data (2006-2018) included 11,813 non-Hispanic Whites, 2216 non-Hispanic Blacks, and 1337 Hispanics aged ≥ 50 years old. Mortality data came from the National Death Index or HRS surveys. Edentulism was self-reported and DM was determined by self-reported diagnosis, medication use, or glycosylated hemoglobin. Cox proportional-hazard models with inverse probability treatment weighting were applied. RESULTS:During mean follow-up of 9.6 years, 2874 Whites, 703 Blacks, and 441 Hispanics died. DM was associated with higher mortality across all groups (Whites: HR = 1.43, 95% CI = 1.25-1.64; Blacks: HR = 1.62, 95% CI = 1.28-2.04; Hispanics: HR = 1.46, 95% CI = 1.07-1.99). However, edentulism predicted higher mortality only in Whites (HR = 1.65, 95% CI = 1.51-1.80). Having both conditions showed highest mortality risk in all groups (Whites: HR = 2.31, 95% CI = 1.56-3.42; Blacks: HR = 1.94, 95% CI = 1.45-2.59; Hispanics: HR = 1.77, 95% CI = 1.16-2.70), with a significant additive interaction observed only in Whites (relative excess risk due to interaction = 0.22, p < 0.05). CONCLUSIONS:DM and edentulism pose an additive risk for mortality in Whites, and there are racial/ethnic differences in edentulism-related mortality.

OBJECTIVE:This study examined racial and ethnic differences in percent total weight loss (%TWL) and glycemic improvement following sleeve gastrectomy (SG) and explored the role of socioeconomic and psychosocial factors in postsurgical outcomes. METHODS:This longitudinal study included patients who underwent SG between 2017 and 2020, with follow-up visits over 24 months. RESULTS:Non-Hispanic Black (NHB) participants had lower %TWL at 3, 12, and 24 months compared with Hispanic (H) and non-Hispanic White (NHW) participants. Fat mass index was initially lower in NHB, with smaller reductions over time and significant group differences persisting at 24 months. NHB participants had higher baseline fat-free mass index values; by 24 months, fat-free mass index values were lower in H participants. Hemoglobin A1c decreased across all groups but remained consistently higher in NHB and H compared with NHW at 24 months. NHB participants reported higher perceived discrimination, sleep disturbance, and perceived stress than H and NHW participants at all time points. Employment status predicted %TWL at 12 months. There was a significant interaction between race and ethnicity and employment status observed at 12 and 24 months, suggesting that employment-related disparities could impact surgical outcomes. CONCLUSIONS:NHB participants experienced less favorable outcomes following SG, emphasizing the need for tailored interventions addressing socioeconomic and psychosocial disparities.

OBJECTIVE:To examine whether patient sociodemographic and clinical characteristics and prior interactions with the healthcare system were associated with opening patient portal messages related to cancer genetic services and beginning services. STUDY SETTING AND DESIGN/METHODS:The trial was conducted in the University of Utah Health (UHealth) and NYU Langone Health (NYULH) systems. Between 2020 and 2023, 3073 eligible primary care patients aged 25-60 years meeting family history-based criteria for cancer genetic evaluation were randomized 1:1 to receive a patient portal message with a hyperlink to a pretest genetics education chatbot or information about scheduling a pretest standard of care (SOC) appointment. DATA SOURCES AND ANALYTIC SAMPLE/UNASSIGNED:Primary data were collected. Eligible patients had a primary care visit in the previous 3 years, a patient portal account, no prior cancer diagnosis except nonmelanoma skin cancer, no prior cancer genetic services, and English or Spanish as their preferred language. Multivariable models identified predictors of opening patient portal messages by site and beginning pretest genetic services by site and experimental condition. PRINCIPAL FINDINGS/RESULTS:Number of previous patient portal logins (UHealth average marginal effect [AME]: 0.32; 95% CI: 0.27, 0.38; NYULH AME: 0.33; 95% CI: 0.27, 0.39), having a recorded primary care provider (NYULH AME: 0.15; 95% CI: 0.08, 0.22), and more primary care visits in the previous 3 years (NYULH AME: 0.09; 95% CI: 0.02, 0.16) were associated with opening patient portal messages about genetic services. Number of previous patient portal logins (UHealth AME: 0.14; 95% CI: 0.08, 0.21; NYULH AME: 0.18; 95% CI: 0.12, 0.23), having a recorded primary care provider (NYULH AME: 0.08; 95% CI: 0.01, 0.14), and more primary care visits in the previous 3 years (NYULH AME: 0.07; 95% CI: 0.01, 0.13) were associated with beginning pretest genetic services. Patient sociodemographic and clinical characteristics were not significantly associated with either outcome. CONCLUSIONS:As system-level initiatives aim to reach patients eligible for cancer genetic services, patients already interacting with the healthcare system may be most likely to respond. Addressing barriers to accessing healthcare and technology may increase engagement with genetic services.

PurposeTo evaluate the association between demographic characteristics and weight-loss in response to financial incentives designed using behavioral economics.DesignRetrospective analysis of randomized clinical trial (RCT).SettingFIReWoRk RCT (NCT03157713), which found that financial incentives were more effective than provision of weight-management resources only for weight-loss.Subjects668 adults with obesity (221 in resources-only group, 447 in incentive groups) living in low-income neighborhoods.MeasuresDemographic characteristics and weight-loss.AnalysisLinear mixed-effects models with interaction terms to examine effect of incentives on weight-loss in different demographic groups.ResultsMean age of participants was 47.69 years, 81.0% were women, 72.6% were Hispanic, and mean BMI was 37.95 kg/m². Financial incentives increased percent weight loss at 6 months (difference in percent weight loss between financial incentive and resources-only group = -2.41%; 95% CI -3.23% to -1.58%). In fully adjusted models, participants who were Black lost less weight than participants who were White (difference in percent weight loss = 2.12%; 95% CI 0.25% to 3.99%). Differences in percent weight loss by sex, age, education and neighborhood income were absent. Models that tested for interactions between group assignment and percent weight loss did not demonstrate evidence of a heterogenous effect of incentives in sociodemographic subgroups.ConclusionBlack participants in the FIReWoRk intervention lost less weight than White participants, but effectiveness of financial incentives generally did not vary significantly by sociodemographic characteristics. However, it remains important to evaluate potential impacts of financial incentive programs on health disparities.

BACKGROUND:Black men are underrepresented in hypertension trials, even though this population has higher prevalence and more adverse sequelae from hypertension, compared to other groups. In this article we present recruitment and community engagement strategies for the Community-to-Clinic Linkage Implementation Program (CLIP), a cluster-randomized trial on hypertension prevention among Black men. METHODS:Using a 2-stage recruitment process: 1) we enrolled Black-owned barbershops from zip-codes with high hypertension prevalence; and 2) recruited Black male participants who fulfilled the eligibility criteria and were customers of the barbershops. Barbershop and participant recruitment was conducted by a partner community-based organization. RESULTS:The study met the recruitment goals for barbershop enrollment (N=22) and individual participants. Of eligible individuals (N=461), 430 enrolled in the study (93% consent rate, exceeding the original enrollment goal of N=420 participants). Throughout recruitment, the study team conducted 101 unique engagements (41 prior to recruitment, 60 during recruitment), totaling engagement with180 partners across all events, including individual and group meetings, attendance at community events, and educational presentations. In addition to a primary partner community organization, the study team collaborated with a Community Advisory Council, comprised of residents, and civic and community leaders, and with the local health department and varied other organizations. CONCLUSIONS:In CLIP, a high number of academic-community engagement encounters and close collaboration with community partners contributed to successful recruitment of Black men at risk for hypertension and with adverse social determinants. Our experience may serve as to inform investigators focused on recruiting underserved populations in hypertension research trials.

IMPORTANCE/UNASSIGNED:In the context of the US opioid crisis, factors associated with the prevalence of opioid use disorder (OUD) must be identified to aid prevention and treatment. State medical cannabis laws (MCL) and recreational cannabis laws (RCL) are potential factors associated with OUD prevalence. OBJECTIVE/UNASSIGNED:To examine changes in OUD prevalence associated with MCL and RCL enactment among veterans treated at the Veterans Health Administration (VHA) and whether associations differed by age or chronic pain. DESIGN, SETTING, AND PARTICIPANTS/UNASSIGNED:Using VHA electronic health records from January 2005 to December 2022, adjusted yearly prevalences of OUD were calculated, controlling for sociodemographic characteristics, receipt of prescription opioids, other substance use disorders, and time-varying state covariates. Staggered-adoption difference-in-difference analyses were used for estimates and 95% CIs for the relationship between MCL and RCL enactment and OUD prevalence. The study included VHA patients aged 18 to 75 years. The data were analyzed in December 2023. MAIN OUTCOME AND MEASURES/UNASSIGNED:International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) or International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) OUD diagnoses. RESULTS/UNASSIGNED:From 2005 to 2022, most patients were male (86.7.%-95.0%) and non-Hispanic White (70.3%-78.7%); the yearly mean age was 61.9 to 63.6 years (approximately 3.2 to 4.5 million patients per year). During the study period, OUD decreased from 1.12% to 1.06% in states without cannabis laws, increased from 1.13% to 1.19% in states that enacted MCL, and remained stable in states that also enacted RCL. OUD prevalence increased significantly by 0.06% (95% CI, 0.05%-0.06%) following MCL enactment and 0.07% (95% CI, 0.06%-0.08%) after RCL enactment. In patients aged 35 to 64 years and 65 to 75 years, MCL and RCL enactment was associated with increased OUD, with the greatest increase after RCL enactment among older adults (0.12%; 95% CI, 0.11%-0.13%). Patients with chronic pain had even larger increases in OUD following MCL (0.08%; 95% CI, 0.07%-0.09%) and RCL enactment (0.13%; 95% CI, 0.12%-0.15%). Consistent with overall findings, the largest increases in OUD occurred among patients with chronic pain aged 35 to 64 years following the enactment of MCL and RCL (0.09%; 95% CI, 0.07%-0.11%) and adults aged 65 to 75 years following RCL enactment (0.23%; 95% CI, 0.21%-0.25%). CONCLUSIONS AND RELEVANCE/UNASSIGNED:The results of this cohort study suggest that MCL and RCL enactment was associated with greater OUD prevalence in VHA patients over time, with the greatest increases among middle-aged and older patients and those with chronic pain. The findings did not support state cannabis legalization as a means of reducing the burden of OUD during the ongoing opioid epidemic.

OBJECTIVE:The objective of this study is to examine real-world dose titration patterns of semaglutide for weight management (Wegovy, Novo Nordisk A/S) in US adults and identify characteristics associated with early discontinuation. METHODS:We identified 15,811 commercially insured adults who started semaglutide for weight management (administrated through single-dose prefilled pens) between June 2021 and December 2023. We depicted dose-titration patterns over 5 months and identified factors associated with discontinuation using multivariable Cox regression. Sensitivity analyses examined patterns after supply shortage resolution (after October 2023). RESULTS:Most semaglutide users deviated from the recommended monthly dose-escalation schedule within the first 5 months. By the fifth month, nearly one-half (46%) had discontinued the treatment, with similar rates (48%) among those initiating after supply stabilization. Discontinuation was strongly associated with copayment amount, with rates increased from 41% in the lowest quintile ($1-$54 per month) to 51% in the highest quintile ($161-$1460 per month). Higher discontinuation rates were also associated with lower household income and education level. CONCLUSIONS:The deviations from the recommended dose-escalation schedule and high discontinuation rate among real-world semaglutide users indicate important challenges in the delivery of evidence-based care. Policy interventions that reduce financial barriers to the persistence of semaglutide are needed.

BACKGROUND:E-cigarettes may serve as a safer alternative to combustible cigarettes and may be more effective than currently available nicotine replacement therapy (NRT). Little is known about the perceptions of using e-cigarettes as part of a smoking treatment program. The objective of this study was to gain insight into patient-level factors to consider when developing smoking treatment programs that incorporate e-cigarettes. METHODS:Qualitative analysis of in-depth interviews with 14 participants enrolled in the e-cigarette treatment arm of a tobacco treatment intervention pilot randomized trial comparing the impact of behavioral counseling paired with e-cigarettes or NRT on smoking outcomes. Participants were prompted to share their experiences with the products and the study overall. Transcripts were coded according to the principles of framework analysis for applied research. Codes were organized into themes using the principles of grounded theory. RESULTS:Themes suggest that while there is an eagerness to try e-cigarettes as a new tool for smoking cessation, there is apprehension regarding what it means to "quit" if switching to e-cigarettes. Reflecting on the transitional purpose of e-cigarettes and potential health concerns associated with their use, many participants differentiated between the short-term goal to quit combustible cigarettes and the long-term goal to quit e-cigarettes. CONCLUSIONS:Including e-cigarettes as an option in smoking treatment regimens may be an opportunity to re-engage people who smoke who have tried and failed to quit with other forms of treatment. Participants found it challenging to establish what it means to quit cigarettes with e-cigarettes due to addiction and other health concerns. Clear guidelines are needed for integrating e-cigarettes into smoking cessation programs. TRIAL REGISTRATIONS/BACKGROUND:ClinicalTrials.gov Identifier: NCT04465318.

BACKGROUND:While a growing body of scientific literature suggests that evidence-based interventions may improve health outcomes in diverse settings, little is known about the best strategies for large-scale implementation. In Africa, music-an important positive social determinant of health-leverages existing cultural values, which may effectively enhance the reach, uptake, and long-term sustainability of evidence-based interventions in the region. To understand how music interventions work, why they are effective, and with whom they resonate, this systematic review aims to evaluate the quality and empirical application of music as an implementation strategy for adopting evidence-based interventions in Africa using the RE-AIM framework as a guide. METHODS:A comprehensive librarian-assisted search followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Five major electronic databases, EBSCOhost, PubMed, Web of Science, Embase, and MEDLINE, were searched for empirical studies focused on using music as an implementation strategy to improve health outcomes in Africa. Two independent investigators extracted components of retrieved papers using the RE-AIM framework as a guide. RESULTS:From 981 citations, eight studies met the inclusion criteria, each reporting a unique music intervention. The interventions were conducted in West Africa (n = 3), South African regions (n = 4), and East Africa (n = 1) and included seven observational studies and one randomized controlled trial (RCT). Using the RE-AIM scoring criteria, we summarize the RE-AIM dimensions reported from selected studies - Adoption (72.5%) being the highest, followed by Reach (62.5%), Implementation (41.7%), and Efficacy/Effectiveness (20.0%). All eight studies (100%) described the intervention location, the expertise of delivery agents, the target population, and the participant characteristics. Moreover, our analysis highlighted the effectiveness of music interventions in enhancing health outcomes, particularly in improving knowledge and awareness (62.5%), facilitating behavioral change (50%), and promoting mental health (25%). CONCLUSION/CONCLUSIONS:Music interventions adapted to the sociocultural context in Africa have the potential to help prevent diseases, improve well-being, and enhance health outcomes. Our review emphasizes the importance of customizing music-based interventions to fit the cultural context, which can enhance the programs' effectiveness, acceptance, and sustainability. Clinical trials are necessary to confirm the efficacy of music interventions in specific medical conditions and from a public health promotion perspective.
