Lifestyle and Long-Term Smoking Cessation

Prediagnosis Smoking Cessation and Overall Survival Among Patients With Non-Small Cell Lung Cancer

Importance

Lung cancer remains the leading cause of cancer-related death globally; non-small cell lung cancer (NSCLC) accounts for 85% of all lung cancer cases, and cigarette smoking is the factor most significantly associated with its risk. However, little is known about the association of years since prediagnosis smoking cessation and cumulative smoking with overall survival (OS) following a lung cancer diagnosis.

Objective

To characterize the association of years since smoking cessation before diagnosis and cumulative smoking pack-years with OS in patients with NSCLC in a lung cancer survivor cohort.

Design, Setting, and Participants

The cohort study involved patients with NSCLC who were recruited to the Boston Lung Cancer Survival Cohort at Massachusetts General Hospital (Boston, Massachusetts) between 1992 and 2022. Patients' smoking history and baseline clinicopathological characteristics were prospectively collected through questionnaires, and OS following lung cancer diagnosis was regularly updated.

Exposures

Duration of smoking cessation before a lung cancer diagnosis.

Main Outcomes and Measures

The primary outcome was the association of detailed smoking history with OS following a lung cancer diagnosis.

Results

Of 5594 patients with NSCLC (mean [SD] age, 65.6 [10.8] years; 2987 men [53.4%]), 795 (14.2%) were never smokers, 3308 (59.1%) were former smokers, and 1491 (26.7%) were current smokers. Cox regression analysis suggested that former smokers had 26% higher mortality (hazard ratio [HR], 1.26; 95% CI, 1.13-1.40; P < .001) and current smokers had 68% higher mortality (HR, 1.68; 95% CI, 1.50-1.89; P < .001) compared with never smokers. Log2-transformed years since smoking cessation before diagnosis were associated with significantly lower mortality among ever smokers (HR, 0.96; 95% CI, 0.93-0.99; P = .003). Subgroup analysis, stratified by clinical stage at diagnosis, revealed that former and current smokers had even shorter OS among patients with early-stage disease.

Conclusions and Relevance

In this cohort study of patients with NSCLC, quitting smoking early was associated with lower mortality following a lung cancer diagnosis, and the association of smoking history with OS may have varied depending on clinical stage at diagnosis, potentially owing to the differing treatment regimens and efficacy associated with smoking exposure following diagnosis. Detailed smoking history collection should be incorporated into future epidemiological and clinical studies to improve lung cancer prognosis and treatment selection.

A Need for Improvement in the Definition of Resistant Arterial Hypertension

With the medical and social importance of resistant arterial hypertension (HTN) in mind, we had three goals in this paper: to study the definitions of resistant HTN in the guidelines on the topic, to analyze them, and to suggest some improvements. We found (at least) eleven insufficiencies in the definition of resistant HTN: (1) different blood pressure (BP) values are used for diagnoses; (2) the number of BP measurements is not specified; (3) the time-frame for the definition is not obtained; (4) it fails to provide normal or target or controlled BP values; (5) secondary HTN is not currently defined as true resistant HTN, but as apparently treatment-resistant HTN; (6) the definition usually directly incorporates BP cut-offs for systolic BP (sBP) and diastolic BP (dBP) making the diagnosis temporary; (7) stress is not included in the exclusion strategy for resistant HTN; (8) there is potentially a need to introduce a category of recovered resistant HTN; (9) to what degree do healthy lifestyle measures have to be fulfilled to consider it as sufficient to change the diagnosis from "apparent treatment-resistant HTN" to the "resistant HTN"; (10) sBP values normal-for-the-age for 61 and 81 year old patients in some guidelines fulfill the criterion for resistant HTN; (11) it probably ought to read "In the absence of contraindications and compelling indications…" in the others. We believe that it is better to use the phrase "above the target BP" for the definition of (treatment) resistant HTN, because the whole story of resistant HTN is related to non-responders to antihypertensive treatment. Therefore, as we treat to target and not to normal values, it is appropriate to define resistant HTN as an insufficiency to reach the target BP values. Moreover, the definition of (treatment) resistant HTN should not be universal for every patient with HTN, but it should be age-related: (treatment) resistant HTN is elevated BP over the target/normal BP values. Using this modification, there will be no need to automatically change the definition of resistant HTN when we change the BP targets in the future.

A randomized controlled trial of contingency management for smoking cessation in substance use treatment patients

Background/Objective

Contingency management (CM) is one of the most effective interventions for smokers with substance use disorder (SUD), and no empirical assessment of its long-term efficacy has been conducted so far in a real-world context. The objectives were: (1) examine the additive effectiveness of CM on cognitive-behavioral treatment (CBT) for smoking cessation, and (2) examine the relationship between smoking cessation and substance use abstinence.

Method

A total of 80 participants (75.8% males; M_age = 45.31; SD = 9.64) were assigned to two smoking cessation treatments: CBT or CBT+CM. A set of generalized estimating equations were conducted to examine the effect of treatment condition on smoking outcomes, as well as the effect of smoking status on substance abstinence.

Results

Adding CM to CBT for smoking cessation improved tobacco abstinence rates at the end-of-treatment (p = .049). Tobacco abstinence rates declined over time (p = .012), but no significant effects of treatment condition were observed across follow-ups (p = .260). Smoking cessation was not significantly related to substance abstinence (p ≥ .488).

Conclusions

CM facilitates early abstinence in smokers with SUD, although effects subside after treatment termination. The lack of association between smoking abstinence and substance use suggests no jeopardizing effects as a result of quitting smoking.

Behavioral Economics and Tobacco Control: Current Practices and Future Opportunities

Despite considerable progress, smoking remains the leading preventable cause of death in the United States. To address the considerable health and economic burden of tobacco use, the development of improved tobacco control and treatment interventions is critical. By combining elements of economics and psychology, behavioral economics provides a framework for novel solutions to treat smokers who have failed to quit with traditional smoking cessation interventions. The full range of behavioral economic principles, however, have not been widely utilized in the realm of tobacco control and treatment. Given the need for improved tobacco control and treatment, the limited use of other behavioral economic principles represents a substantial missed opportunity. For this reason, we sought to describe the principles of behavioral economics as they relate to tobacco control, highlight potential gaps in the behavioral economics tobacco research literature, and provide examples of potential interventions that use each principle.

Health Behavior of Adolescent Smokers During Covid-19 Pandemic

AIM: This research aims to determine the health behavior of adolescent smokers during the COVID-19 pandemic. METHOD: Both quantitative and qualitative analyses were conducted simultaneously using the design of “t” and Chi-square test through the distribution of questionnaires to 135 respondents as well as descriptive design and case studies, respectively. The data were collected by 13 informants through in-depth interviews, observation, and documentation. RESULTS: The results showed that 5 out of the 6 indicators of the demographic characteristics were correlated to the economic pressure of the families of adolescent smokers which also correlates with their health behavior during the COVID-19 pandemic. CONCLUSION: The increase in the price of cigarettes and family control are measures that regulate children from buying cigarettes.
