RESUMO
INTRODUCTION: This study aimed to assess the role of the rs16969968 variant of nicotinic receptor alpha-5 subunit in regulating smoking behavior and nicotine intake in response to nicotine manipulations among dependent smokers in a naturalistic environment. METHODS: Sixty-nine adults (19 females) smoking 10 or more cigarettes per day were asked to complete four 2-week study phases during which they smoked exclusively one of two types of Spectrum nicotine research cigarettes (FTC nicotine yield 0.8 and 1.6 mg, respectively), their usual brand of cigarettes, or their usual brand of cigarettes while wearing a 21-mg nicotine patch. Measurements included rs16969968 genotype, number of cigarettes per day, smoking topography, and plasma cotinine. RESULTS: Compared to controls (G/G carriers), A allele carriers reported smoking 4 to 5 more cigarettes per day across all conditions (all ps < .05). Mean total smoke volume per day and cotinine were greater in A allele carriers than in controls (ps = 0.05, 0.046, respectively). No significant genotype differences were found in smoking compensation indices for the switch from Medium to High nicotine yield cigarettes. Nicotine patch-induced reductions in cigarettes smoked per day and total smoke volume per day showed significant interactions between genotype and pre-patch levels, heavier smokers showing greater effects of genotype (p = .052 and p =.006, respectively). CONCLUSIONS: Results suggest that the rs16969968 variants regulate heaviness of smoking primarily by their impact on daily numbers of cigarettes smoked, but no genotype differences were found in smoking compensation after switching from Medium to High nicotine cigarettes. IMPLICATIONS: The differences in daily cigarette consumption between rs16969968 risk-allele carriers and controls are shown to be consistent regardless of manipulations of cigarette nicotine content and transdermal nicotine supplementation and markedly greater among dependent smokers than those observed in the general smoker populations. G/G allele carriers, relative to A allele carriers, appeared to be more sensitive to the nicotine patch manipulation, reducing their smoking to a greater extent. These findings support continued efforts in the development of personalized intervention strategies to reduce the rs16969968-conveyed genetic propensity for heavy smoking.
RESUMO
INTRODUCTION: Available evidence is mixed concerning associations between smoking status and COVID-19 clinical outcomes. Effects of nicotine replacement therapy (NRT) and vaccination status on COVID-19 outcomes in smokers are unknown. METHODS: Electronic health record data from 104 590 COVID-19 patients hospitalized February 1, 2020 to September 30, 2021 in 21 U.S. health systems were analyzed to assess associations of smoking status, in-hospital NRT prescription, and vaccination status with in-hospital death and ICU admission. RESULTS: Current (n = 7764) and never smokers (n = 57 454) did not differ on outcomes after adjustment for age, sex, race, ethnicity, insurance, body mass index, and comorbidities. Former (vs never) smokers (n = 33 101) had higher adjusted odds of death (aOR, 1.11; 95% CI, 1.06-1.17) and ICU admission (aOR, 1.07; 95% CI, 1.04-1.11). Among current smokers, NRT prescription was associated with reduced mortality (aOR, 0.64; 95% CI, 0.50-0.82). Vaccination effects were significantly moderated by smoking status; vaccination was more strongly associated with reduced mortality among current (aOR, 0.29; 95% CI, 0.16-0.66) and former smokers (aOR, 0.47; 95% CI, 0.39-0.57) than for never smokers (aOR, 0.67; 95% CI, 0.57, 0.79). Vaccination was associated with reduced ICU admission more strongly among former (aOR, 0.74; 95% CI, 0.66-0.83) than never smokers (aOR, 0.87; 95% CI, 0.79-0.97). CONCLUSIONS: Former but not current smokers hospitalized with COVID-19 are at higher risk for severe outcomes. SARS-CoV-2 vaccination is associated with better hospital outcomes in COVID-19 patients, especially current and former smokers. NRT during COVID-19 hospitalization may reduce mortality for current smokers. IMPLICATIONS: Prior findings regarding associations between smoking and severe COVID-19 disease outcomes have been inconsistent. This large cohort study suggests potential beneficial effects of nicotine replacement therapy on COVID-19 outcomes in current smokers and outsized benefits of SARS-CoV-2 vaccination in current and former smokers. Such findings may influence clinical practice and prevention efforts and motivate additional research that explores mechanisms for these effects.

INTRODUCTION: This study explored the efficacy of combination lorcaserin and nicotine patch for smoking cessation treatment and prevention of postsmoking cessation weight gain. METHODS: We conducted a trial in which 61 adult daily smokers were asked to quit smoking using a combination of lorcaserin and nicotine patch. During the first 2 weeks of treatment prior to the quit day, participants were randomized to receive either lorcaserin (10 mg twice daily) plus nicotine patch (21 mg) or placebo plus nicotine patch (21 mg). Following this 2-week period, participants received both medications for 12 weeks. Outcomes included 4-week continuous smoking abstinence at the end of treatment (weeks 7-10 postquit attempt), weight change, ad libitum smoking, withdrawal symptoms, and ratings of cigarette reward. RESULTS: Biochemically confirmed continuous smoking abstinence from 7 to 10 weeks postquit attempt was 31.1% (90% confidence interval, 21.4%-40.8%). Participants who quit smoking showed no weight gain; in fact, mean weight change was minus 0.16 kg (SD = 3.27) over the study period. There was an unexpected but strong association (p = .006) between a decrease in sensory enjoyment of smoking and successful quit outcome on this regimen. During the prequit randomization period, lorcaserin versus placebo reduced the impact of smoking to relieve craving for cigarettes as well as the sensory enjoyment of smoking (p = .005). Adherence and tolerability to lorcaserin and nicotine patch was good. CONCLUSIONS: The combination of lorcaserin and nicotine patch was well tolerated, associated with a relatively high smoking abstinence rate, and effectively prevented weight gain associated with quitting smoking. IMPLICATIONS: This report provides an important contribution to the literature because it details evidence of a medication combination-lorcaserin and nicotine-that is effective for smoking cessation and for ameliorating weight gain associated with smoking cessation. For many smokers, postcessation weight gain is a major obstacle to quitting, and this medication combination provides a suitable treatment option for these smokers.

BACKGROUND: Many smokers are unable to access effective behavioral smoking cessation therapies due to location, financial limitations, schedule, transportation issues or other reasons. We report results from a prospective observational study in which a promising novel behavioral intervention, Mindfulness Training for Smokers was provided via web-based video instruction with telephone-based counseling support. METHODS: Data were collected on 26 low socioeconomic status smokers. Participants were asked to watch eight video-based classes describing mindfulness skills and how to use these skills to overcome various core challenges in tobacco dependence. Participants received eight weekly phone calls from a smoking cessation coach who provided general support and answered questions about the videos. On the quit day, participants received two weeks of nicotine patches. RESULTS: Participants were a mean of 40.5 years of age, smoked 16.31 cigarettes per day for 21.88 years, with a mean of 6.81 prior failed quit attempts. Participants completed a mean of 5.55 of 8 online video classes with a mean of 23.33 minutes per login, completed a mean of 3.19 of 8 phone coach calls, and reported a mean meditation practice time of 12.17 minutes per day. Smoking abstinence was defined as self-reported abstinence on a smoking calendar with biochemical confirmation via carbon monoxide breath-test under 7 parts per million. Intent-to-treat analysis demonstrated 7-day point prevalence smoking abstinence at 4 and 6-months post-quit of 23.1% and 15.4% respectively. Participants showed a significant pre- to post-intervention increase in mindfulness as measured by the Five-Factor Mindfulness Questionnaire, and a significant pre- to post-intervention decrease in the Anxiety Sub-scale of the Depression Anxiety and Stress Scale. CONCLUSIONS: Results suggest that Mindfulness Training for Smokers can be provided via web-based video instruction with phone support and yield reasonable participant engagement on intervention practices and that intervention efficacy and mechanism of effect deserve further study.

We report the results of a randomized trial comparing a novel smoking cessation treatment Mindfulness Training for Smokers (MTS) to a usual care therapy (Controls), which included the availability of a tobacco quit line and nicotine patches. Data were collected from 196 low socioeconomic status smokers in 2010-2011 in Madison, Wisconsin. Participants were randomized to either MTS or a telephonic quit line. The primary outcome was 6-month smoking abstinence measured by carbon monoxide breath testing and Time-Line Follow-Back. Among treatment initiators (randomized participants who participated in the intervention), abstinence rates were significantly different between the MTS (38.7%) and control (20.6%, p = .05) groups. Study limitations are also discussed. Results suggest that further study is warranted.

As mindfulness-based interventions become increasingly widespread, interest has grown in better understanding which features of these treatments produce beneficial effects. The present study examined the relative contribution of mindfulness practice time and practice quality in predicting psychological functioning (negative affect, emotion regulation, quality of life, mindfulness). Data were drawn from a randomized clinical trial of mindfulness training for smokers and assessed outcomes at posttreatment (n = 43) and 5-month follow-up (n = 38). The intervention included instruction in mindfulness techniques targeted to smoking cessation and relapse prevention and was composed of 10 group meetings over 8 weeks. Data from 8 treatment groups were used. Mindfulness practice quality was measured weekly over the course of treatment, and multilevel modeling was used to estimate trajectories of change in practice quality. The measure of practice quality was shown to be valid and reliable, with change in practice quality predicting change in psychological functioning at both posttreatment (ß = .31, 95% CI = [0.04, 0.56], p = .022) and follow-up (ß = .45 [0.16, 0.73], p = .002), even when controlling for practice time. Practice time predicted outcomes at posttreatment (ß = .31 [0.05, 0.57], p = .019) but not at follow-up (ß = .16 [-0.14, 0.47], p = .293). Neither practice time nor change in practice quality predicted smoking abstinence at 1 month or 6 months postquit. Results support the importance of practice quality as a relevant aspect of mindfulness interventions.

BACKGROUND: Many organizations recommend clinicians use structured communication processes, referred to as "shared decision making," to improve patient-reported outcomes for patients considering lung cancer screening (LCS). RESEARCH QUESTION: Which components of high-quality patient-centered communication are associated with decision regret and distress? STUDY DESIGN AND METHODS: We conducted a prospective, longitudinal, repeated measures, cohort study among patients undergoing lung cancer screening in three different healthcare systems. We surveyed participants using validated measures of decision regret, decision satisfaction, distress, and patient-clinician communication domains up to a year after the low-dose computed tomography (LDCT) for LCS. For longitudinal analyses, we applied a series of generalized estimating equations to measure the association of the "patient as person" communication domain, screening knowledge, and decision concordance with decision regret and distress. RESULTS: When assessed 2-4 weeks after the LDCT, 202 (58.9%) and 8 (2.3%) of 343 total respondents reported mild and moderate/severe decision regret, respectively, while 29 (9.2%) participants of 315 total reported mild distress and 19 (6.0%) moderate or greater distress. The mean ± SD decision satisfaction scores (0 to 10 scale) were 9.82 ± 0.89, 9.08 ± 1.54, and 6.13 ± 3.40 among those with no, mild, and moderate/severe regret respectively. Distress scores remained low after the LDCT, even among those with nodules. Patient-centered communication domains were not associated with decision regret or distress. INTERPRETATION: Patients undergoing LCS rarely experience moderate or greater decision regret and distress. Although many participants reported mild decision regret, most were very satisfied over the year after their LDCT for LCS. Communication processes were not associated with regret and distress, suggesting that it may be challenging for communication interventions to reduce the harms of LCS.
RESUMO
BACKGROUND: We report results of a pilot study designed to test a novel smoking cessation intervention, Mindfulness Training for Smokers (MTS), in smokers age 18-29 years with regular episodes of binge drinking. Mindfulness is a cognitive skill of applying close moment-to-moment attention to experience with a mental posture of acceptance and non-reactivity. The MTS intervention consisted of six weekly classes that provided instruction on how to use mindfulness to manage known precursors of smoking relapse including smoking triggers, strong emotions, stressful situations, addictive thoughts, urges, and withdrawal symptoms. METHODS: The MTS intervention was compared to Interactive Learning for Smokers (ILS), a time/intensity matched control group using daily non-directed walking instead of mindfulness meditation. Recruitment was conducted primarily at local technical colleges. Primary outcome measures included biochemically-confirmed smoking abstinence and reduction in alcohol use at the end of treatment (2-weeks post-quit attempt). RESULTS: The sample (N = 55) was 70.9% male, with a mean age of 21.9 years, and a mean of 11.76 alcoholic drinks consumed per week. Intent-to-treat analysis showed biochemically-confirmed 7-day point prevalence abstinence rates at 2-weeks post-quit for MTS = 20.0% and ILS = 4.0%, p = .08. Secondary analysis showed number of drinks per week in the first 2-weeks post-quit correlated with smoking relapse at 2-weeks post-quit (p < .01). CONCLUSIONS: This pilot study demonstrated that Mindfulness Training for Smokers shows promise for smoking cessation and alcohol use reduction in treating young adult smokers with alcohol abuse. Results suggest the need for a study with larger sample size and methods that reduce attrition. TRIAL REGISTRATION: ClnicalTrial.gov, NCT01679236.

OBJECTIVE: Mindfulness-based interventions have enjoyed a marked increase in support within biomedical and psychological research and practice in the past two decades. Despite the widespread application of these treatments for a range of psychological and medical conditions, there remains a lack of consensus regarding mechanisms through which these interventions effect change. One plausible yet underexplored mechanism is the therapeutic alliance between participants and mindfulness instructors. METHODS: In this report, data are presented on therapeutic alliance from the mindfulness arm (n = 37) of a randomized controlled trial of a mindfulness-based smoking cessation treatment. RESULTS: Results suggest that client-reported therapeutic alliance measured midtreatment did not significantly predict primary smoking outcomes. Alliance did predict improvement in posttreatment scores on several outcome variables linked to mindfulness practice, including emotion regulation (ß = -.24, p = .042), mindfulness (ß = .33, p = .007), negative affect (ß = -.33, p = .040), as well as treatment compliance (ß = .39, p = .011). CONCLUSION: Implications of these relationships and the possible role of therapeutic alliance in mindfulness treatments are explored.

Undergraduate premedical students face a formidable decision as they work to determine whether to pursue a profession in medicine. Exposure to clinical medicine and research is essential to inform students what it might be like to be a physician. Undergraduates, however, face a number of obstacles to obtaining the kind of quality clinical and research experience needed to make an informed decision. Growing regulations designed to protect patient confidentiality, though undeniably important, pose a barrier to students seeking patient contact. Traditional passive physician shadowing often does not provide ample opportunities for one-on-one patient interaction or problem solving. Finally, research opportunities available to students typically are not associated with clinical work and therefore do not provide an experiential model of how empirical evidence informs medical practice. This report describes the University of Wisconsin School of Medicine and Public Health's Tobacco Science Scholars Program, a pilot program designed to address some of these barriers. While fulfilling institutional requirements for patient contact, the program provides students with an active model of clinical patient interaction and problem solving, with a research experience integrated into these clinical experiences so that undergraduates better understand how research informs clinical medicine.

Objectives: Compare financial barriers to the most effective smoking cessation medications - varenicline and combination nicotine replacement therapy (CNRT) across major insurance categories and determine whether these financial barriers impact smoking cessation outcomes. Study design: Longitudinal retrospective observational cohort study. Methods: Patients seen at Duke Smoking Cessation Program 05/2016 through 07/2021 were studied. Those prescribed varenicline or CNRT were determined to have financial barriers to access if they could not purchase the medication using insurance or their own funds. Outcomes were compared between Medicare, Medicaid, and private insurers. Abstinence was defined as self-reported 7-day smoking abstinence. Results: Patients with Medicare were 5.08 times more likely to face a financial barrier to highly effective smoking cessation medications compared to patients with private insurance (p<0.00001) and 2.81 times more likely compared to Medicaid (p<0.00001). Patients able to access these highly effective medications achieved a smoking abstinence rate that was 1.58 times higher than those who could not (p = 0.01). Conclusions: Findings suggest Medicare coverage of the most effective smoking cessation medications is considerably worse than Medicaid or private insurance; inability to access these medications may lead to lower rates of smoking abstinence.
RESUMO
Importance: Adaptive pharmacotherapy, ie, starting a medication regimen and then modifying that regimen based on patient response, is common in many medical domains but is not common in smoking cessation. Recently, studies have found that adaptive treatment using precessation nicotine patches is efficacious for smoking cessation; however, adaptive treatment using precessation varenicline and adaptive treatment in clinical practice settings have not been fully assessed. Objective: To determine whether adaptive pharmacotherapy leads to higher smoking abstinence rates than standard pharmacotherapy in a clinical practice setting. Design, Setting, and Participants: This double-blinded stratified placebo-controlled randomized clinical trial compared adaptive treatment with standard treatment for smoking cessation. The study was conducted at a university health system in Durham, North Carolina, from February 2018 to May 2020 and was stopped early due to COVID-19. Data were analyzed as intent-to-treat from May 24, 2021, to February 27, 2022. Interventions: Participants were allowed to choose varenicline or nicotine patches and were then randomized to adaptive or nonadaptive (standard) treatment. Participants started on their chosen medication (adaptive) or placebo (standard) 4 weeks before their target quit day. Two weeks later, participants were assessed for treatment response. Adaptive participants who did not decrease daily cigarettes smoked by at least 50% (nonresponders) received bupropion in addition to their chosen medication. Participants in the adaptative treatment group who did decrease daily cigarettes smoked by at least 50% (responders) and participants in the standard treatment group received additional placebo bupropion. Participants in the standard treatment group received varenicline starting 1 week before the target quit date or nicotine patches starting on the target quit day. All participants received brief behavioral support. Main Outcome and Measures: The main outcome was biochemically verified 30-day continuous smoking abstinence 12 weeks after their target quit smoking day. Other measures included demographic characteristics, smoking history, and repeated smoking assessments. Results: Of the planned 300 participants, a total of 188 participants (mean [SD] age, 49.1 [12.5] years; 102 [54%] female) were enrolled before the trial was stopped because of the COVID-19 pandemic. A total of 127 participants chose to use varenicline, including 64 randomized to adaptive treatment and 63 randomized to standard treatment, and 61 participants chose to use nicotine patches, including 31 randomized to adaptive treatment and 30 randomized to standard treatment. At baseline, participants smoked a mean (SD) of 15.4 (7.3) cigarettes per day. At 12 weeks after the target quit day, biochemically verified 30-day continuous smoking abstinence was observed in 23 of 95 participants (24%) in the adaptive treatment group and 8 of 93 participants (9%) in the standard treatment (odds ratio [OR], 3.38; 95% CI, 1.43-7.99; P = .004); among participants who used varenicline, 30-day continuous abstinence was 18 participants (28%) in the adaptive treatment group, and 5 participants (8%) in the standard treatment group (OR, 4.54; 95% CI, 1.57-13.15); among participants who used nicotine patches, 30-day continuous abstinence was 5 participants (16%) in the adaptive treatment group and 3 participants (10%) in the standard treatment group (OR, 1.73; 95% CI, 0.38-7.99). Sleep problems were more common for participants in the varenicline adaptive treatment group than in the varenicline standard treatment group (rate ratio, 1.74; 95% CI, 1.18-2.58; P = .03). Conclusions and Relevance: This randomized clinical trial found that adaptive pharmacotherapy was efficacious for smoking cessation treatment in a practice setting. Trial Registration: ClinicalTrials.gov Identifier: NCT02501265.

RATIONALE: Electronic nicotine delivery systems (ENDS) are used by smokers seeking to reduce combustible cigarette (CC) use, but the role of nicotine replacement vs. behavioral and sensory factors is still poorly understood. We hypothesized that providing nicotine from ENDS in addition to nicotine skin patches would promote smoking reduction relative to non-nicotine control ENDS. OBJECTIVES: To assess the effects on smoking behavior of using nicotine vs. placebo ENDS in smokers using nicotine vs. placebo patches. METHODS: Ninety-four daily smokers were enrolled in a study that randomly assigned them to receive ENDS with nicotine vs. without nicotine and skin patches with vs. without nicotine. Smoking reduction and cessation were assessed over an 8-week period by self-report and by expired air carbon monoxide (CO) measurements. The primary outcome was defined as reduction in expired air CO. RESULTS: The use of nicotine in ENDS led to significant reductions in smoking (ENDS nicotine vs. placebo difference in CO change = -9.2 ppm; 90% CI (-1.5 ppm, -16.9 ppm)) and was highly correlated with reductions in self-reported cigarettes per day (r=0.6). The effect of nicotine in nicotine patches was not statistically significant (patch nicotine vs. placebo difference in CO change = -0.1 ppm; 90% CI (-7.8 ppm, 7.6 ppm)). CONCLUSIONS: The presence of nicotine in ENDS was associated with a large reduction in smoking. Additional studies will be needed to determine whether there may be additive effects of nicotine ENDS and nicotine patches on smoking abstinence.

BACKGROUND: There is mixed evidence about the relations of current versus past cancer with severe COVID-19 outcomes and how they vary by patient and cancer characteristics. METHODS: Electronic health record data of 104,590 adult hospitalized patients with COVID-19 were obtained from 21 United States health systems from February 2020 through September 2021. In-hospital mortality and ICU admission were predicted from current and past cancer diagnoses. Moderation by patient characteristics, vaccination status, cancer type, and year of the pandemic was examined. RESULTS: 6.8% of the patients had current (n = 7,141) and 6.5% had past (n = 6,749) cancer diagnoses. Current cancer predicted both severe outcomes but past cancer did not; adjusted odds ratios (aOR) for mortality were 1.58 [95% confidence interval (CI), 1.46-1.70] and 1.04 (95% CI, 0.96-1.13), respectively. Mortality rates decreased over the pandemic but the incremental risk of current cancer persisted, with the increment being larger among younger vs. older patients. Prior COVID-19 vaccination reduced mortality generally and among those with current cancer (aOR, 0.69; 95% CI, 0.53-0.90). CONCLUSIONS: Current cancer, especially among younger patients, posed a substantially increased risk for death and ICU admission among patients with COVID-19; prior COVID-19 vaccination mitigated the risk associated with current cancer. Past history of cancer was not associated with higher risks for severe COVID-19 outcomes for most cancer types. IMPACT: This study clarifies the characteristics that modify the risk associated with cancer on severe COVID-19 outcomes across the first 20 months of the COVID-19 pandemic.

Few studies exist showing that involvement in lung cancer screening (LCS) leads to a change in rates of cigarette smoking. We investigated LCS longitudinally to determine whether teachable moments for smoking cessation occur downstream from the initial provider-patient LCS shared decision-making discussion and self-reported effects on smoking behaviors. We performed up to two successive semi-structured interviews to assess the experiences of 39 individuals who formerly or currently smoked cigarettes who underwent LCS decision-making discussions performed during routine care from three established US medical center LCS programs. The majority of those who remembered hearing about the importance of smoking cessation after LCS-related encounters did not report communication about smoking influencing their motivation to quit or abstain from smoking, including patients who were found to have pulmonary nodules. Patients experienced little distress related to LCS discussions. Patients reported that there were other, more significant, reasons for quitting or abstinence. They recommended clinicians continue to ask about smoking at every clinical encounter, provide information comparing the benefits of LCS with those of quitting smoking, and have clinicians help them identify triggers or other motivators for improving smoking behaviors. Our findings suggest that there may be other teachable moment opportunities outside of LCS processes that could be utilized to motivate smoking reduction or cessation, or LCS processes could be improved to integrate cessation resources.
RESUMO
Background: Implementation mapping (IM) is a promising five-step method for guiding planning, execution, and maintenance of an innovation. Case examples are valuable for implementation practitioners to understand considerations for applying IM. This pilot study aimed to determine the feasibility of using IM within a federally qualified health center (FQHC) with limited funds and a 1-year timeline. Methods: An urban FQHC partnered with an academic team to employ IM for implementing a computerized strategy of tobacco cessation: the 5A's (Ask, Advise, Assess, Assist, Arrange). Each step of IM was supplemented with theory-driven methods and frameworks. Data collection included surveys and interviews with clinic staff, analyzed via rapid data analysis. Results: Medical assistants and clinicians were identified as primary implementers of the 5A's intervention. Salient determinants of change included the perceived compatibility and relative priority of 5A's. Performance objectives and change objectives were derived to address these determinants, along with a suite of implementation strategies. Despite indicators of adoptability and acceptability of the 5A's, reductions in willingness to adopt the implementation package occurred over time and the intervention was not adopted by the FQHC within the study timeframe. This is likely due to the strain of the COVID-19 pandemic altering health clinic priorities. Conclusions: Administratively, the five IM steps are feasible to conduct with FQHC staff within 1 year. However, this study did not obtain its intended outcomes. Lessons learned include the importance of re-assessing barriers over time and ensuring a longer timeframe to observe implementation outcomes.

MAIN OBJECTIVE: There is limited information on how patient outcomes have changed during the COVID-19 pandemic. This study characterizes changes in mortality, intubation, and ICU admission rates during the first 20 months of the pandemic. STUDY DESIGN AND METHODS: University of Wisconsin researchers collected and harmonized electronic health record data from 1.1 million COVID-19 patients across 21 United States health systems from February 2020 through September 2021. The analysis comprised data from 104,590 adult hospitalized COVID-19 patients. Inclusion criteria for the analysis were: (1) age 18 years or older; (2) COVID-19 ICD-10 diagnosis during hospitalization and/or a positive COVID-19 PCR test in a 14-day window (+/- 7 days of hospital admission); and (3) health system contact prior to COVID-19 hospitalization. Outcomes assessed were: (1) mortality (primary), (2) endotracheal intubation, and (3) ICU admission. RESULTS AND SIGNIFICANCE: The 104,590 hospitalized participants had a mean age of 61.7 years and were 50.4% female, 24% Black, and 56.8% White. Overall risk-standardized mortality (adjusted for age, sex, race, ethnicity, body mass index, insurance status and medical comorbidities) declined from 16% of hospitalized COVID-19 patients (95% CI: 16% to 17%) early in the pandemic (February-April 2020) to 9% (CI: 9% to 10%) later (July-September 2021). Among subpopulations, males (vs. females), those on Medicare (vs. those on commercial insurance), the severely obese (vs. normal weight), and those aged 60 and older (vs. younger individuals) had especially high mortality rates both early and late in the pandemic. ICU admission and intubation rates also declined across these 20 months. CONCLUSIONS: Mortality, intubation, and ICU admission rates improved markedly over the first 20 months of the pandemic among adult hospitalized COVID-19 patients although gains varied by subpopulation. These data provide important information on the course of COVID-19 and identify hospitalized patient groups at heightened risk for negative outcomes.

Cigarette smoking remains disproportionately prevalent and is increasingly a cause of death and disability among people with HIV (PWH). Many PWH are interested in quitting, but interest in and uptake of first-line smoking cessation pharmacotherapies are varied in this population. To provide current data regarding experiences with and perceptions of smoking cessation and cessation aids among PWH living in Durham, North Carolina, the authors conducted five focus group interviews (total n = 24; 96% African American) using semistructured interviews. Interviews were recorded, transcribed, coded, and thematically analyzed. Major themes included ambivalence and/or lack of interest in cessation; presence of cessation barriers; perceived perceptions of ineffectiveness of cessation aids; perceived medication side effects; and conflation of the harms resulting from use of tobacco products and nicotine replacement therapy. Innovative and effective interventions must account for the aforementioned multiple barriers to cessation as well as prior experiences with and misperceptions regarding cessation aids.

ABSTRACT: Smoking is disproportionately prevalent among people living with HIV (PLWH) compared with the general population. We conducted five focus groups (n = 24) using semi-structured interview guides to explore perceptions and experiences of smoking and cessation-related interactions with health care providers among smokers with HIV. Major themes included a limited understanding of how smoking affects illness among PLWH and minimal discussion about cessation with providers. Findings highlight the need to educate smokers with HIV about the known impacts of smoking on illness among PLWH and to facilitate greater discussion of cessation between providers and smokers with HIV. Prior experiences with smoking cessation medications and desire for additional information regarding these medications should be considered when implementing medication regimens in research and clinical settings.

INTRODUCTION: Light smoking (smoking ≤ 10 cigarettes per day or on some days) has become increasingly prevalent in the US and increases morbidity and mortality. Many light smokers do not experience significant nicotine withdrawal but instead smoke in response to cues. Minimal evidence exists supporting interventions to help light smokers quit smoking. METHODS: We present results from a proof-of-concept pilot study designed to evaluate the feasibility and acceptability of a cue-based smoking cessation intervention targeted to light daily and intermittent smokers. Participants were randomized to one of two arms: Arm 1) standard smoking cessation treatment or Arm 2) standard smoking cessation treatment + enhanced cue-based treatment that included interactive texting to extend cue exposure treatment to real-world settings and cue management counseling.Outcomes included feasibility (number of participants who were recruited and who completed the intervention), acceptability (intervention ratings), and preliminary efficacy (7-day point prevalence abstinence). RESULTS: We randomized 24 English and Spanish-speaking light smokers, 13 to the treatment arm and 11 to the control arm. Across both arms, 77% attended all counseling sessions, 90% rated these sessions as very useful and 100% said that they would recommend the intervention to a friend. 15% in the treatment arm had biochemically-validated smoking abstinence compared to 0% in the standard counseling arm. CONCLUSIONS: Results from this proof-of-concept study demonstrated that a cue-based intervention is feasible and acceptable among light smokers and suggests the need for a fully powered study to assess this approach.
