E-Cigarette Use and Depression Among American Indian Adults Who Smoke.

Objective: This study examined the association of e-cigarette use status and history of depression among American Indian (AI) adults who smoke.

Method: We conducted a secondary data analysis using survey data from 375 AI adult smokers collected in 2016 at a tribally operated healthcare facility in northeast Oklahoma. Multivariable logistic regression was used to estimate the association between e-cigarette use and self-reported history of depression while adjusting for potential confounders.

The impact of non-tobacco e-cigarette flavoring on e-cigarette uptake, cigarette smoking reduction, and cessation: A secondary analysis of a nationwide clinical trial.

Introduction: The impact of e-cigarette flavoring on e-cigarette uptake and switching to e-cigarettes among adults who smoke is critical to e-cigarette regulation in the United Sates. The purpose of this secondary analysis was to assess the impact of e-cigarette flavoring choice on e-cigarette uptake and changes in cigarette smoking in a large nationwide trial of e-cigarette provision in the United States.

Methods: A free four-week supply of e-cigarettes was provided with minimal instructions to use to adults who smoke (N = 427).

E-Cigarette switching and financial incentives to promote combustible cigarette cessation among adults accessing shelter services: A pilot study.

Background: Smoking prevalence among U.S. adults experiencing homelessness is ≥70 %.

E-cigarette market share by nicotine claims.

Background: Nicotine forms (salt vs. freebase) and isomers (synthetic vs. tobacco-derived) are key characteristics of e-cigarettes that manufacturers manipulate, and "tobacco-free" claims may have served to attract new consumers and increase their intention to use.

Correlates of susceptibility to waterpipe tobacco smoking in young adults.

Introduction: Many US young adults are susceptible to waterpipe (i.e., hookah) tobacco smoking (WTS) initiation, but research on factors associated with WTS susceptibility is limited.

Universal smoking machine adaptor for tobacco product testing.

Significance: Historically, tobacco product emissions testing using smoking machines has largely focused on combustible products, such as cigarettes and cigars. However, the popularity of newer products, such as electronic cigarettes (e-cigarettes), has complicated emissions testing because the products' mouth-end geometries do not readily seal with existing smoking and vaping machines. The demand for emissions data on popularly used products has led to inefficient and non-standardised solutions, such as laboratories making their geometry-specific custom adaptors and/or employing flexible tubing, for each unique mouth-end geometry tested.

Testing the feasibility of mobile ecological momentary assessment for symptom burden and management among metastatic cancer patients.

Background: Individuals who have metastatic cancer experience substantial physical and psychological distress (e.g., pain, depression, anxiety) from their disease and its treatment compared to patients with less advanced disease.

An observational human laboratory assessment of nicotine delivery, vaping topography and subjective effects of usual brand electronic cigarette use among young adults.

Aims: To measure nicotine delivery, vaping topography and subjective effects of current generations of disposable, cartridge-based and other types of electronic cigarettes (e-cigarettes) among young adults.

Design, Setting, Participants: Observational, human laboratory assessment of e-cigarette use in Columbus, Ohio, USA (July 2020 to June 2021). Participants (n = 96, 60.

Smoking cessation, harm reduction, and biomarkers protocols in the PhenX Toolkit: Tools for standardized data collection.

The use of standard protocols in studies supports consistent data collection, improves data quality, and facilitates cross-study analyses. Funded by the National Institutes of Health, the PhenX (consensus measures for otypes and eposures) Toolkit is a catalog of recommended measurement protocols that address a wide range of research topics and are suitable for inclusion in a variety of study designs. In 2020, a PhenX Working Group of smoking cessation experts followed a well-established consensus process to identify and recommend measurement protocols suitable for inclusion in smoking cessation and smoking harm reduction studies.

Examining the Predictive Utility of Behavioral Economic Demand Indices and Subjective Effects on the Actualized Reinforcing Value of Menthol Cigarettes and Potential Alternatives.

Introduction: Considering recent and proposed bans on menthol cigarettes, methods are needed to understand the substitutability of potential menthol cigarette alternatives (MCAs) for menthol cigarettes. This study examined the prospective relationship between behavioral economic demand indices and subjective effects of usual brand menthol cigarettes (UBMC) and preferred MCAs with subsequent performance on a laboratory-based concurrent-choice task comparing UBMC and MCAs.

Methods: Eighty participants who typically smoked menthol cigarettes completed this clinical laboratory study.

The therapeutic alliance between study participants and intervention facilitators is associated with acute effects and clinical outcomes in a psilocybin-assisted therapy trial for major depressive disorder.

We examined if the therapeutic alliance between study participants and intervention facilitators in a psilocybin-assisted therapy (PAT) trial changed over time and whether there were relationships between alliance, acute psilocybin experiences, and depression outcomes. In a randomized, waiting list-controlled clinical trial for major depressive disorder in adults (N = 24), participants were randomized to an immediate (N = 13) or delayed (N = 11) condition with two oral doses of psilocybin (20mg/70kg and 30mg/70kg). Ratings of therapeutic alliance significantly increased from the final preparation session to one-week post-intervention (p = .

Associations of inter-annual rainfall decreases with subsequent HIV outcomes for persons with HIV on antiretroviral therapy in Southern Africa: a collaborative analysis of cohort studies.

Background: Periods of droughts can lead to decreased food security, and altered behaviours, potentially affecting outcomes on antiretroviral therapy (ART) among persons with HIV (PWH). We investigated whether decreased rainfall is associated with adverse outcomes among PWH on ART in Southern Africa.

Methods: Data were combined from 11 clinical cohorts of PWH in Lesotho, Malawi, Mozambique, South Africa, Zambia, and Zimbabwe, participating in the International epidemiology Databases to Evaluate AIDS Southern Africa (IeDEA-SA) collaboration.

Nicotine Delivery and Changes in Withdrawal and Craving During Acute Electronic Cigarette, Heated Tobacco Product, and Cigarette Use Among a Sample of Black and White People Who Smoke.

Introduction: E-cigarettes and heated tobacco products (HTPs) may serve as potential options for harm reduction for smokers if they possess reward profiles similar to cigarettes. Little is known about the abuse liability of HTPs and e-cigarettes versus cigarettes in racial/ethnic minority smokers.

Aims And Methods: Twenty-two nicotine-deprived people who smoke (black [n = 12] and white [n = 10]) completed three visits that included a standardized 10-puff bout followed by a 50-minute ad libitum use assessment with their usual brand cigarette (UBC), an e-cigarette, and HTP.

Evaluating the effects of nicotine concentration on the appeal and nicotine delivery of oral nicotine pouches among rural and Appalachian adults who smoke cigarettes: A randomized cross-over study.

Background And Aims: Oral nicotine pouches (ONPs) probably offer reduced harm compared with cigarettes, but independent data concerning their misuse liability are lacking. We compared nicotine delivery and craving relief from ONPs with different nicotine concentrations to cigarettes.

Design: This was a single-blind, three-visit (≥ 48-hour washout), randomized-cross-over study.
