RESUMEN

Violent behaviour perpetrated against women has long-lasting negative physical and mental health consequences for women, their children, their families, and their communities. Intimate partner violence (IPV) is associated with many adverse physical, psychological, and emotional consequences. Structural racism and historical trauma affect women's trust and further hinder the ability of Indigenous and Black women to seek help after experiencing IPV. The availability of IPV support services, which can include shelter, food, group therapy, legal assistance, and advocacy, can be inaccessible to women due to the inability to access often limited resources in urban environments and reasons compounded by potential geographic distance if living in rural areas or living in community. Understanding the unique reasons why Indigenous and Black women do not seek help, and the barriers they experience when seeking help after IPV, is critical. Pandemics have the potential to create further complexities on how IPV is experienced. Black and Indigenous women experiencing IPV were therefore at even greater risk for IPV-related harm because of state and local "stay at home" measures put in place to minimise the spread COVID-19. The purpose of this manuscript is to explicate the methods for a large R01 study in the Upper Midwest.

RESUMEN

OBJECTIVES: We are in the midst of an overdose epidemic that has grown during the concurrent COVID-19 pandemic. In Wisconsin, overdose deaths increased 11-fold from 2000 to 2020, with over 1200 deaths in 2020. Because of disparities in substance use initiation, relapse, and treatment success among racially minoritized women, this study's purpose was to investigate overdose death rates among Black and Indigenous women in Wisconsin from 2018 to 2020. METHODS: Overdose death rates were examined under the following parameters: sex, race (Black, Indigenous, White), age, year, and manner of death. Logistic regression analysis was also conducted looking at death count data, with race, age, and year as potential predictor variables. RESULTS: Death rates (per 100,000) in 2018 were 14.1 (12.6-15.5) for White women, 20.8 (14.7-26.9) for Black women, and 26.5 (10.0-42.9) for Indigenous women; these rates increased in 2020 to 16.4 (14.8-17.9), 32.5 (25.0-40.0), and 59.9 (35.8-84.0) for White, Black, and Indigenous women, respectively. Regression findings illustrated that being Black or Indigenous and aged 15 to 44 or 45 to 64 years were significantly more likely to die from most causes of death (any drug, any opioid, prescription opioid, heroin, synthetic opioids, and cocaine; adjusted odds ratios > 1.25, P s < 0.001). CONCLUSIONS: This study confirms that deaths in Wisconsin are disproportionately higher in female minoritized populations. Understanding the complex intricacies between the impacts of the COVID-19 pandemic coupled with barriers to treatment access or acceptability in these populations is urgently needed. It will take a multipronged approach to address the overdose epidemic and better serve these marginalized, vulnerable populations.

RESUMEN

INTRODUCTION: Despite evidence showing Latinos' high prevalence of mental health, little is known about Latina migrant farmworkers' mental health experiences, especially those working in Midwestern states. Considering the multiple vulnerabilities observed among Latina migrant farmworkers, it is necessary to gain insight from own accounts and perceptions of mental health and mental health-seeking experiences. METHOD: A qualitative descriptive approach, using in-depth semi-structured interviews with open-ended questions, served to retrieve data from 34 Latina migrant farmworkers. This study was informed by Chicana, postcolonial, and Black feminist epistemologies. RESULTS: Thematic analysis identified themes within the data. These findings pertained to the conceptualization of mental health within the contexts of family, capacities, stigma, denial, and faith. DISCUSSION: Our results demonstrate the need for health care providers to consider Latina migrant farmworkers' perceptions about mental health and apply those in designing and implementing culturally informed policy and practice.

RESUMEN

Intimate partner violence (IPV) is a complex and pervasive public health problem disproportionately affecting Indigenous and Black women. During the COVID-19 pandemic, IPV became more complicated for advocates because social distancing, quarantine, and isolation measures further endangered women experiencing IPV. This manuscript is based on an ongoing community-engaged study in an upper Midwestern state. Our primary goal for this study is to generate urgently needed knowledge on the impact of the COVID-19 pandemic on Indigenous and Black women's help-seeking behaviours following IPV by systematically documenting barriers women faced during the pandemic. Engaging women in a large study that seeks to garner information about their experiences of violence is complex and challenging and requires significant planning, especially for ensuring participants' safety. In this write-up, we detail the safety planning protocol developed for the purposes of recruiting and engaging women in rural and urban areas in an upper Midwestern state in the United States. Our goal is to provide scholars conducting research in the area of violence with practical considerations for safely conducting a study of this nature.

RESUMEN

Resumen Objetivo: Describir los factores que pueden determinar la reducción de los síntomas en el trastorno de ansiedad generalizada y trastorno por estrés postraumático, mediante estimulación magnética transcraneal en combinación con terapia de extinción. Material y Métodos: Se realizó una búsqueda en bases de datos (Cochrane, EBSCO, Pubmed, Sciencedirect y Wiley), con las palabras clave "transcranial magnetic stimulation", "human", "fear extinction". Los criterios de selección incluyen estudios en humanos, tratamientos con terapia de extinción y EMT, en donde se registre la conductancia de la piel como variable de respuesta. Resultados: Existe poca investigación que cumpla con los criterios de la presente revisión bibliográfica. Se obtuvieron 5 artículos enfocados en el tratamiento de síntomas como el miedo y la recurrencia de recuerdos traumáticos. Los protocolos de estimulación son heterogéneos, la frecuencia de estimulación va de 1 Hz a 30 Hz. La estimulación de alta frecuencia fue la más utilizada. La duración máxima de los efectos reportados fue de 1 mes. Conclusiones: La EMT junto con la terapia de extinción como tratamiento para TEPT y TAG es un campo de estudio que requiere de más investigación. Los resultados sobre su eficacia no son concluyentes, el tamaño de muestra es pequeño y es necesario identificar qué protocolos son eficaces a largo plazo. Los estudios clínicos con pacientes que presenten estos trastornos son relevantes para conocer los efectos de aquellos protocolos que han sido exitosos en pacientes sanos (condicionados al miedo).


Abstract Objective: To describe the factors that can determine the reduction of symptoms in generalized anxiety and posttraumatic stress disorders by transcranial magnetic stimulation in combination with extinction therapy. Material and methods: A bibliographic review was conducted in databases (Cochrane, EBSCO, PubMed, ScienceDirect y Wiley), using the keywords: "transcranial magnetic stimulation", "human" and "fear extinction". A selection of clinical trials that used extinction therapy plus TMS and the skin conductance as variable quantified was made. Results: Five articles focused on the treatment of symptoms, like fear and recurrence of traumatic memories were obtained. There is little research on the topic. Stimulation protocols are heterogeneous between studies (stimulation frequency ranges from 1 to 30 Hz). Most of the studies reviewed reported the use of high-frequency stimulation. The maximum duration of therapeutic effects reported was one month. Conclusions: TMS and extinction therapy as a treatment for PTSD and GAD has a growing research field. Effectiveness results are not conclusive, sample sizes are small, and studies do not focus on which protocols are effective in the long-term. New studies that include patients with diagnosed PTSD and GAD are relevant to assess the protocols that have already been successful in healthy patients (fear-conditioned).

RESUMEN

ABSTRACT: Traditional substance misuse treatments have not always taken women or marginalized populations into consideration. A holistic approach that addresses how drugs may be used to cope with trauma caused by violence, poverty, and neglect as well as employment of engagement strategies that connect populations with culturally relevant support systems are key, especially in treating African American women. As substance misuse rates rise among African American women, characterizing how this may influence or be influenced by relationships (such as with children, intimate partners, and social relations) is especially important in the context of effective treatment. The purpose of this qualitative study was to examine the themes surrounding substance misuse and close relationships among women previously enrolled in a transitional housing treatment program grounded in social support. Many women discussed how the program itself was an impetus in addressing not only their own substance use but also intergenerational substance use within their families. Women also noted how relationships with their children were vastly different pretreatment compared with during and after treatment, specifically emphasizing a positive improvement. Regarding intimate relationships, African American women learned to establish assertiveness and navigate healthier social relationships, all while sustaining drug abstinence. It is important to acknowledge the role of the healthcare professional in ensuring effective and culturally relevant treatment for African American women; nursing curricula should include evidence-based practice education and training on mental health and substance misuse specific to marginalized communities to more deeply understand the complex intersections of substance misuse, poverty, and social relationships in the lives of women.

RESUMEN

American Indian1 (AI) women experience high rates of intimate partner violence (IPV) and face many barriers when help-seeking. This study aims to understand better the context of IPV and help-seeking behaviors for urban AI women after experiences with IPV. Postcolonial and Indigenous feminist frameworks framed this critical ethnography study. Semistructured interviews with 34 AI IPV survivors2 living in Wisconsin urban areas were conducted. Our findings highlight context-specific structural barriers to help-seeking after experiences of IPV heightened by the COVID-19 pandemic. Context-specific and survivor-led interventions are necessary to address and reduce barriers that urban AI women face.

RESUMEN

INTRODUCTION: How nicotine dependence will be affected when current smokers initiate electronic cigarette (e-cigarette) use to reduce cigarette smoking is unknown. This study evaluated cigarette, e-cigarette, and total nicotine dependence more than 6 months among smokers reducing cigarette consumption by replacing with e-cigarettes. AIMS AND METHODS: Adult cigarette smokers were randomized to one of four conditions (36 mg/ml e-cigarette, 8 mg/ml e-cigarette, 0 mg/ml e-cigarette, or cigarette-substitute [CS] [provided at no cost]) and instructed to reduce their cigarette smoking by 75% at 1 month. Participants completed follow-up at 1, 3, and 6 months. The Penn State Nicotine Dependence Index (PSNDI) measured dependence on cigarettes (PSCDI) and e-cigarettes (PSECDI). Urine cotinine measured total nicotine exposure. Linear mixed effects models for each outcome were conducted and included interaction terms between visit and condition. RESULTS: Participants (n = 520) were 58.8% female, 67.3% White, and 48.0 years old. At baseline, the median number of cigarettes smoked per day was 17.3 and the mean PSCDI score was 13.4, with no significant differences between conditions. Participants in the e-cigarette conditions reported significantly lower PSCDI scores, compared with baseline, and with the CS condition at all follow-up visits. Those in the 36 mg/ml e-cigarette condition reported greater PSECDI scores at 6 months, compared with baseline and the 0 mg/ml and 8 mg/ml conditions. At all follow-up visits, there were no differences in total nicotine exposure compared to baseline, nor between any conditions. CONCLUSIONS: E-cigarette use was associated with reduced cigarette dependence, compared to the CS, without significant increases in total nicotine exposure. IMPLICATIONS: Initiation of electronic cigarette use while continuing to smoke could potentially increase nicotine dependence. In this randomized trial aimed at helping smokers to reduce their cigarette intake, we found that use of an e-cigarette was associated with a reduction in cigarette dependence and an increase in e-cigarette dependence (in the condition with the highest nicotine concentration only), with no long term increase in total nicotine dependence or nicotine exposure.

RESUMEN

Women experiencing homelessness who are also survivors of violence require uniquely tailored programs to accommodate complex needs. To understand how violence shaped the lives of formerly homeless African American women, an instrumental case study design and community-based participatory research approach was utilized in this qualitative study. Focus group interviews with graduates (N = 40) from a long-term transitional housing program were conducted. Using thematic analysis, identified themes included: cycles of violence, violence in the community, relationships with children, and coping with violence. These themes illustrated survivors' growth through supportive programming and highlighted services dedicated to empowering women who have experienced violence.

RESUMEN

Through the lens of Black Feminist Thought, the intersectionality of poverty, racism, and sexism in the lives of urban dwelling African American women was explored. Reflections on recovery among women previously enrolled in a transitional housing treatment program were gathered via semistructured interviews, using an instrumental case study design. Four major themes surrounding the context of recovery were identified and analyzed: Knowledge and awareness of addiction, importance of social support and support groups, peace of mind that resulted from a new lifestyle, and women's desire to maintain their recovery status. Many women did not realize that their drug use constituted an addiction prior to their enrollment in the program. Social support and support groups such as AA, NA, and AODA helped the women to maintain their recovery, and this newfound recovery resulted in additional stress relief. Finally, many women felt empowered to maintain their recovery, not only for themselves but also their children. Paradigm shifts in treatment and recovery processes are needed to better serve minority populations, specifically focusing on women and African Americans. Recovery services must shift from previously male centered, hegemonic, pathology-oriented treatment modalities to serve populations more efficiently and equitably. Furthermore, to create effective social change in recovery, programs must address the social determinants of substance misuse, addictive behaviors, and underlying structural inequalities resulting from the intersection of racism, sexism, and classism. Deeper understandings of complex social issues must be disseminated, particularly for women battling substance misuse who are homeless, racially discriminated against and marginalized.

RESUMEN

OBJECTIVE: To understand communities' perceptions, beliefs, and health-related behavior choices related to COVID-19 in order to guide public health nursing communication and interaction with patients and the community. DESIGN: A qualitative study, guided by the Health Belief Model (HBM), strove to comprehend the perceptions and reactions to COVID-19 among Wisconsinites. SAMPLE: Twenty-five diverse Wisconsin residents aged 18 or older. MEASUREMENTS: Semi-structured interviews provided information about individuals' attitudes, perceptions, and reactions to COVID-19. Interviews were audio-recorded, transcribed, and thematic analysis was conducted to identify themes. RESULTS: We identified three major themes: (1) "health care starts way before you ever enter the doors of a healthcare facility"; (2) "to live in a society is to help each other"; and (3) mental health as impacted by COVID-19. CONCLUSIONS: This study demonstrated the need for greater public health support, as well as the role of Social Determinants of Health. Understanding perceptions and reactions to COVID-19 can help public health nurses understand and better respond to future pandemics.

RESUMEN

The purpose of this theoretical article is to analyze the utility of postcolonial, Black, and Chicana feminist frameworks to inform nursing research and practice specific to mental health needs of Latina women migrant farmworkers. Twentieth-century Western feminist narratives overlooked the intersecting systems of oppression experienced by women of color, including Latina women. Feminist epistemologies are useful in understanding the complex sociopolitical contexts that have impacted women's health outcomes and well-being. This analysis is critical to shaping nursing care that meets the unique health needs of migrant farmworker women while considering their sociopolitical realities.

RESUMEN

African American women are at higher risk of poor mental ill health compared with other racial and ethnic groups in the United States. For low-income and homeless African American populations, the risk of poor mental ill health is even higher. The purpose of our study was to learn what programmes at a long-term transitional living centre helped at-risk and homeless African American mothers to succeed on their own, in accordance with self-identified goals. We conducted ten focus group interviews with 39 graduates of a long-term transitional living centre located in a Midwestern city, and an individual interview with the founder of that centre (N = 40). Our study was informed by Black Feminist Thought, Life Course Theory, and an instrumental case study design. Thematic analysis was used to identify patterns in the qualitative data collected. Findings pertaining to mental health included impacts of adverse childhood experiences, lack of social networks, child placement in foster care, and implications on self-esteem and self-worth. Our findings demonstrate the need for healthcare providers to take into account the intersecting factors facing African American women experiencing homelessness undergirded by systemic racism, which impacts their mental health and well-being.

RESUMEN

OBJECTIVE: To learn how adverse childhood experiences (ACEs) impacted the life course trajectory of formerly homeless and at-risk African American women. DESIGN: Intersectionality and life course theory informed this qualitative pilot study, based on an instrumental case study design. SAMPLE: Forty previously homeless and at-risk African American women, who were graduates from a long-term transitional living facility in Milwaukee, Wisconsin. MEASUREMENTS: Focus group interviews and one individual interview provided data about participants' life experiences prior to, during, and following their time at the transitional living facility, which provided supportive wrap-around services. Interviews were audiotaped, transcribed, and line-by-line thematic analysis was conducted to identify themes. Fifteen focus group participants also completed ACE questionnaires. RESULTS: Participants reported a high prevalence of multiple ACEs, and three themes were identified: childhood experiences with family conflict, childhood experiences of abuse, and negative coping mechanisms. One-hundred percent of women had experienced at least one ACE, based on ACE questionnaire responses. CONCLUSIONS: ACEs affect various parts of patient's lives as adults. For nurses and other healthcare professionals, connecting with community resources provides the opportunity to strategically approach health improvement with wrap-around resources to improve health outcomes.

RESUMEN

INTRODUCTION: The extent to which use of electronic nicotine delivery systems (ENDS) for smoking reduction leads to cigarette abstinence in smokers with no plans to quit smoking is unclear. This exploratory analysis examined the effects of ENDS delivering different amounts of nicotine on cigarette abstinence up to 24-week follow-up, in comparison to placebo or a behavioral substitute. METHODS: This four-arm parallel-group, randomized, placebo-controlled trial took place at two academic medical centers in the United States (Penn State Hershey and Virginia Commonwealth University). Participants were current adult smokers (N = 520) interested in reducing but not planning to quit. They received brief advice and were randomized to one of four 24-week conditions, receiving either an eGo-style ENDS paired with 0, 8, or 36 mg/ml nicotine liquid (double-blind) or a cigarette-shaped tube, as a cigarette substitute (CS). Self-reported daily cigarette consumption and exhaled carbon monoxide (CO) were measured at all study visits. Outcomes included intent-to-treat, self-reported 7-day cigarette abstinence, biochemically confirmed by exhaled CO at 24 weeks after randomization. RESULTS: At 24 weeks, significantly more participants in the 36 mg/ml condition (14/130, 10.8%) than in the 0 mg/ml condition (1/130, 0.8%) and the CS condition (4/130, 3.1%) were abstinent (relative risk = 14 [95% CI = 1.9-104.9] and 3.5 [95% CI = 1.2-10.4], respectively). The abstinence rate in the 8 mg/ml condition was 4.6% (6/130). CONCLUSIONS: When smokers seeking to reduce smoking tried ENDS, few quit smoking in the short term. However, if smokers continued to use an ENDS with cigarette-like nicotine delivery, a greater proportion completely switched to ENDS, as compared with placebo or a cigarette substitute. IMPLICATIONS: The extent to which use of electronic nicotine delivery systems (ENDS) for smoking reduction leads to cigarette abstinence in smokers with no plans to quit smoking was unclear. This randomized trial found that ENDS with nicotine delivery approaching that of a cigarette are more effective in helping ambivalent smokers to quit cigarette smoking.

RESUMEN

BACKGROUND: Electronic nicotine delivery systems (ENDSs) are used by some smokers to reduce cigarette consumption, but their effectiveness is uncertain. We aimed to examine the extent to which ENDSs or a non-nicotine cigarette substitute influence tobacco-related toxicant exposure and cigarette consumption in smokers interested in smoking reduction. METHODS: We did a four-arm, parallel-group, randomised controlled trial at two sites in the USA (Penn State University, Hershey, PA, and Virginia Commonwealth University, Richmond, VA). We enrolled adults aged 21-65 years who smoked more than nine cigarettes per day (for at least the past year), with exhaled CO of more than 9 parts per million at screening, who were not currently using an ENDS, and who were interested in reducing smoking but not quitting. Participants were randomised (site-specific with allocation concealment; 1:1:1:1) to receive either a cartomiser-based, pen-style ENDS (eGo-style) paired with 0, 8, or 36 mg/mL liquid nicotine (participants and researchers masked to concentration) or a non-ENDS cigarette-shaped plastic tube that delivered no nicotine or aerosol (cigarette substitute; unmasked) for 24 weeks. Conditions were chosen to reflect a range of nicotine delivery including none (cigarette substitute and 0 mg/mL ENDS), low (8 mg/mL), and cigarette-like (36 mg/mL), and all conditions were paired with smoking reduction instructions. The primary outcome was concentration of the tobacco-specific carcinogen metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL; urinary total) collected at randomisation and at 4, 12, and 24 weeks. Multiple imputation with and without covariate adjustment was used in addition to sensitivity analyses. This trial is registered with ClinicalTrials.gov, NCT02342795. FINDINGS: Between July 22, 2015, and Nov 16, 2017, 684 individuals were screened and 520 (76%) were enrolled and randomised. 188 (36%) of 520 participants were lost to follow-up by week 24; attrition did not differ by study group (39 [30%] of 130 in the cigarette substitute group, 56 [43%] of 130 in the ENDS with 0 mg/mL nicotine group, 49 [38%] of 130 in the ENDS 8 mg/mL group, and 44 [34%] of 130 in the ENDS 36 mg/mL group). Urinary total NNAL at 24 weeks in the ENDS with 36 mg/mL nicotine group was 210·80 pg/mg creatinine (95% CI 163·03-274·42) compared with 346·09 pg/mg creatinine (265·00-455·32) in the cigarette substitute group (p=0·0061). No other significant differences between groups were observed for any time point for urinary total NNAL. Serious adverse event frequency was similar across groups (12 events in 12 participants [9%] in the ENDS with 36 mg/mL nicotine group, seven events in six participants [5%] in the 8 mg/mL group, 11 events in ten participants [8%] in the 0 mg/mL group, and 13 events in 13 participants [10%] in the cigarette substitute group), and all of these were deemed unrelated or unlikely to be related to study product use. There was one death between randomisation and 24 weeks (suicide; in the ENDS with 0 mg/mL nicotine group). INTERPRETATION: Use of an ENDS with cigarette-like nicotine delivery can reduce exposure to a major pulmonary carcinogen, NNAL, even with concurrent smoking. Future ENDS trials should involve products with well characterised nicotine delivery, including those with nicotine delivery approaching that of a cigarette.

RESUMEN

Diabetes is caused by insufficient insulin production from pancreatic beta cells or insufficient insulin action, leading to an inability to control blood glucose. While a wide range of treatments exist to alleviate the symptoms of diabetes, therapies addressing the root cause of diabetes through replacing lost beta cells with functional cells remain an object of active pursuit. We previously demonstrated that genetic deletion of Fstl3, a critical regulator of activin activity, enhanced beta cell number and glucose-responsive insulin production. These observations suggested the hypothesis that FSTL3 neutralization could be used to therapeutically enhance beta cell number and function in humans. To pursue this possibility, we developed an FSTL3-neutralizing antibody, FP-101, and characterized its ability to prevent or disrupt FSTL3 from complexing with activin or related ligands. This antibody was selective for FSTL3 relative to the closely related follistatin, thereby reducing the chance for off-target effects. In vitro assays with FP-101 and activin revealed that FP-101-mediated neutralization of FSTL3 can enhance both insulin secretion and glucose responsiveness to nonfunctional mouse and human islets under conditions that model diabetes. Thus, FSTL3 neutralization may provide a novel therapeutic strategy for treating diabetes through repairing dysfunctional beta cells.

RESUMEN

This qualitative study assessed the impact of the Nia Imani model of care on homeless African-American women, many of whom abused drugs, experienced interpersonal violence, and faced other challenges when seeking to improve their lives and health. Nia Imani Family, Inc., is Milwaukee, Wisconsin's, only long-term transitional living facility. Grounded in Black feminist thought, our study included focus group interviews with 39 women who had lived at Nia Imani, and successfully completed its programs; and one individual interview with the founder, who had also experienced homelessness (N=40). Themes were identified through thematic analysis, and included the following: crucial social support, learning self-worth, stability and structure, appreciation for strict rules, and importance of parenting and financial literacy classes. To ensure effective interventions, there is a need for nurses to understand how community-based and community-led programs, like Nia Imani, impact the health and well-being of African-American women, who have experienced homelessness.

RESUMEN

BACKGROUND: A rapidly evolving tobacco marketplace highlights the timeliness of the FDA's authority to regulate tobacco, specifically the role that flavorings in nicotine-containing electronic cigarette (ECIG) liquids have on public health. This study aimed to evaluate the extent to which ECIG liquid flavor and nicotine concentration influenced subjective measures of abuse liability among young adult cigarette (cig) smokers. METHODS: Young adult (18-21 y.o.) smokers (M = 10.1 cig/day, no regular ECIG use history) completed 7 Latin-square ordered conditions each preceded by 12 h. nicotine/tobacco abstinence. Conditions were own brand cig (OB) and eGo-style ECIG paired with three liquid flavors (cream, tropical fruit, tobacco/menthol) varying in nicotine concentration (0 or 36 mg/ml). Products were administered in two 10-puff bouts in each condition. Heart rate/blood pressure (HR/BP) and tobacco/nicotine abstinence symptoms, nicotine/general drug effects, and acceptability measures were assessed repeatedly throughout sessions. Mixed linear models were followed-up with Tukey's HSD t-tests. RESULTS: HR/BP indicated nicotine exposure during nicotine-containing conditions. OB and tobacco/menthol 36 mg/ml conditions produced significant decreases in ratings of cig smoking urges. Nicotine/drug effects were elevated significantly for OB and 36 mg/ml ECIG conditions with one exception noted for the tobacco/menthol 0 mg/ml condition. OB had the highest acceptability ratings, and ECIG condition results varied by acceptability item. CONCLUSIONS: Among young adult smokers, ECIG conditions containing nicotine were positively associated with several subjective measures of abuse liability but not all. Flavors did not consistently mask/enhance effects observed. Results reinforce continued examination of ECIG-delivered nicotine and liquid flavors in relationship to abuse liability.
