Smoking Cessation Interventions in the Lung Cancer Screening Setting: A Randomized Clinical Trial.

Importance: The optimal configuration of a smoking cessation intervention in a lung cancer screening (LCS) setting has not yet been established.

Objective: To evaluate the efficacy of 3 tobacco treatment strategies of increasing integration and intensity in the LCS setting.

Design, Setting, And Participants: In this randomized clinical trial, LCS-eligible current smokers were randomized into 3 treatments: quitline (QL), QL plus (QL+), or integrated care (IC).

Effects of Varenicline, Bupropion, Nicotine Patch, and Placebo on Treating Smoking Among Persons With Current or Past Major Depressive Disorder: Secondary Analysis of a Double-Blind, Randomized, Placebo-Controlled Trial.

Objective: The aim of this study was to compare the safety and efficacy of the leading smoking cessation medications among individuals with current versus past major depressive disorder (MDD).

Methods: This was a secondary analysis of a randomized, double-blind trial over 12 weeks with varenicline or bupropion, followed by a 12-week assessment, in participants ages 18-75 with past (N=2,174) or current (N=451) MDD or without psychiatric disorders (N=4,028). Interventions included 12 weeks of pharmacotherapy with placebo, nicotine replacement therapy (NRT; nicotine patch), bupropion, or varenicline, and brief counseling.

Survival Outcomes of an Early Intervention Smoking Cessation Treatment After a Cancer Diagnosis.

Importance: Smoking after a cancer diagnosis increases mortality and risk for a second cancer.

Objective: To determine the association between time of entry into a smoking cessation intervention following a cancer diagnosis and survival outcomes.

Design, Setting, And Participants: Using a prospective cohort study design, patients with cancer who smoked and received cessation treatment were assessed at 3 months, 6 months, and 9 months following tobacco treatment onset.

Covalent Lysozyme Immobilization on Enzymatic Cellulose Nanocrystals.

Nanostructured materials represent promising substrates for biocatalyst immobilization and activation. Cellulose nanocrystals (CNCs), accessible from waste and/or renewable sources, are sustainable and biodegradable, show high specific surface area for anchoring a high number of enzymatic units, and high thermal and mechanical stability. In this work, we present a holistic enzyme-based approach to functional antibacterial materials by bioconjugation between the lysozyme from chicken egg white and enzymatic cellulose nanocrystals.

Comparing the Fagerström Test and Heaviness of Smoking Index in Predicting Smoking Abstinence in Cancer Patients.

Introduction: People with cancer who smoke exhibit greater cigarette dependence than people without cancer who smoke, a crucial factor in smoking cessation. Research is limited on the predictive potential of the Fagerström Test for Cigarette Dependence (FTCD) and the Heaviness of Smoking Index (HSI) on smoking abstinence in cancer patients undergoing smoking cessation treatment.

Aims And Methods: We analyzed data from 5934 cancer patients seeking smoking cessation treatment at The University of Texas MD Anderson Cancer Center (female 52.
