Smoking cessation intervention within the framework of a lung cancer screening program: preliminary results and clinical perspectives from the "Cosmos-II" Trial.

Data coming from the literature investigating the effectiveness and interaction between smoking cessation (SC) and lung cancer screening (LCScr) are still sparse and inconsistent. Herein, we report the preliminary results from the ongoing lung cancer screening trial ("Cosmos-II") focusing our analysis on the inter-relationship between the SC program and the LCScr.

Implementation of smoking ban: a survey in a public hospital setting.

Smoking in hospitals is banned in most of European countries; nevertheless, implementing a total smoking ban is particularly difficult and policy breaches are frequent. Aim of our study was to monitor the compliance with the smoke-free policy within a hospital district by measuring particulate matters (PM2.5). We designed an observational study and identified six sensitive locations within the hospitals: surgical units, administrative offices, hall, outdoor main entrances and as controls an outdoor and an indoor area. To rule out potential confounders we included in the evaluation the roadways surrounding the hospital district. PM2.5 median concentrations observed in outdoor main entrances and in hall were significantly higher (16.4 and 13.4 µg m(-3)), as compared with the other settings (P < 0.0001). This data warrant an implementation of current policies to protect patients, visitors and employees from passive second-hand smoke leading to a smoking prohibition in any hospital surroundings.

Cytisine for smoking cessation: A 40-day treatment with an induction period.

INTRODUCTION: Cytisine is a smoking cessation drug now used worldwide. Most of the data available in the literature predict a 25-day treatment, accepted on the basis of previous clinical experience in Eastern Europe. There are few studies on dosing, and only recently some researchers have tried a longer treatment period. METHODS: This real-world retrospective cross-sectional study analyzed data collected consecutively from 2015 to 2021, in seven smoking cessation centers in north-central Italy. The aim of this study is to evaluate the effectiveness and tolerability of a 40-day cytisine treatment with an induction phase and a slower reduction schedule. Data were collected from a group of 871 patients treated with cysteine, varenicline, and nicotine replacement therapy (NRT). The sample was not randomized. Behavioral support (4-6 sessions, each lasting 20-30 min, plus the evaluation session) was delivered to all patients. RESULTS: Subgroups taking cytisine (n=543 for 40 days), varenicline (n=281 for 12 weeks), and NRT (n=47 for eight weeks) showed biochemically confirmed smoking abstinence at 6 months of 50.5%, 55.9%, and 51.0%, respectively, with a statistically significant difference between cytisine versus varenicline (p<0.01) but not between cytisine versus NRT (p=0.5597). Adverse events were 4.4% with cytisine and 33.3% with varenicline. Behavioral support was an important factor in effectiveness. CONCLUSIONS: This study produced preliminary evidence that the 40-day regimen of cytisine, appears to have less effectiveness in comparison to varenicline but the magnitude of the effect is comparable. The results and tolerability seem to be better than in most other studies.

Smoking cessation in the management of Chronic Obstructive Pulmonary Disease (COPD): narrative review and recommendations.

BACKGROUND: The percentage of smokers who develop COPD (Chronic Obstructive Pulmonary Disease) peaks at 40-50% in most recent publications. SUMMARY: Tobacco smoke remains the main cause of COPD, though smoking-related limitation of the flow is rather subjective. For patients who keep on smoking, general practitioners (GPs) and pulmonologists should be able to offer smoking cessation programs as an important part of COPD treatment. This narrative article aims to provide the scientific basis to help healthcare professionals develop this therapy; with this aim in mind, the authors have analyzed the most recent literature. KEY MESSAGES: Only 3% of smokers who try to quit without availing themselves of any support succeed. Effective smoking cessation methods are counselling and pharmacotherapy, which, combined together, are credited with a 24% success rate. Although there are no therapeutic novelties with strong scientific evidence for smoking cessation, it is however advisable to keep the literature updated to new devices and new digital therapies.

Self-reported compliance with drug therapy during the first SARS-CoV-2 Italian lockdown in patients with respiratory disease.

BACKGROUND: Low compliance with drug therapy in patients with chronic respiratory diseases was a well-known issue even before the coronavirus pandemic, but its causes are not yet fully defined. OBJECTIVE: To verify the adherence to drug therapy in patients with respiratory disease during the COVID-19 pandemic. METHODS: From June to September 2020, about 700 patients of the Forlanini Hospital who had been unmonitored during the March-May 2020 lockdown in Italy received a questionnaire during the pneumological check-up based on self-reported information on compliance with therapy during lockdown. RESULTS: 284 out of the 418 returned questionnaires could be used in this study: 179 patients (63.0%) responded positively to the continuation of therapy, 18 (6.3%) reduced the dosage of their medication and 82 (28.9%) interrupted the therapy. CONCLUSIONS: The low percentage of patients that reduced their drug dosage may be due to an increased awareness of drug treatment benefits, and may also be ascribed to the Government healthcare strategy during lockdown.

Electronic cigarette use among Italian smokers: patterns, settings, and adverse events.

OBJECTIVE: Information is scanty on the patterns and settings of electronic cigarette use and on its possible adverse events. To fill the knowledge gap on these issues, we conducted a survey among ever-smokers attending smoking cessation services (SCS) in Italy. METHODS: In 2016-2018, we enrolled 395 ever-smokers aged ⩾18 years who were current or former electronic cigarette users in 12 SCS from northern, central, and southern Italy. RESULTS: In all, 12.4% of ever smokers were regular, 9.4% occasional, and 78.2% past users of electronic cigarettes. Of all users, 93.8% consumed electronic cigarettes with nicotine, 95.9% used refillable devices, and 76.6% purchased electronic cigarette devices or liquids in vape shops. The mean duration of use was 3.7 months and the mean number of puffs per day was 86. Among users, 71.5% used electronic cigarettes in at least 1 smoke-free indoor environment, 53.7% in workplaces, 49.5% in restaurants and bars, 33.5% in train/metro stations or airports, and 18.4% in public transports. The use of electronic cigarettes in smoke-free environments significantly decreased with age and increased with duration of use and nicotine dependence. In our sample, 47.1% reported at least 1 adverse event attributable to electronic cigarette use: 19.5% dry cough, 12.0% dry mouth, 7.6% throat or mouth irritation, and 6.8% sore throat. CONCLUSION: In Italy, most conventional cigarette smokers use electronic cigarettes where smoking conventional cigarettes is prohibited. About half of users reported 1 or more symptoms attributable to electronic cigarettes, despite the relatively short duration of use.

Use of varenicline in smokeless tobacco cessation influences sleep quality and dream recall frequency but not dream affect.

OBJECTIVE: Varenicline (VCL) treatment has become popular as a part of smoking-cessation therapies, even though its possible implications in neuropsychiatric adverse events include abnormal sleep and nightmares. Our study is the first aimed at prospectively investigating changes in sleep and dream measures across such treatment by using a one week sleep diary and collecting dream recall (DR). METHODS: Thirty-eight smokers participated in two different effective smoking-cessation programs: 25 subjects received VCL, 13 subjects received nicotine replacement therapy (NRT). Participants were requested to fill out a sleep diary and audio-record dreams for one week, both at baseline assessment (T0) and after two weeks from the beginning of treatment (T1). Differences in sleep and dream measures were tested using mixed Analysis of Covariance with time (T0 vs T1) as a within-subject factor and group (VCL vs NRT) as a between-subject factor, considering age as a covariant. RESULTS: Sleep measures showed a significant increase in the number of awakenings in the VCL group at T1 compared to T0. The VCL group reported an increase in DR rate at T1. These sleep and dream measures were intercorrelated, but only at T1 and during VCL treatment. CONCLUSIONS: The correlations between DR rate and sleep fragmentation measures underlined that VCL cannot be considered as a direct cause of abnormal dreams. Comparisons between groups cast some doubts on the actual existence of abnormal dreams, at least as compared to the NRT group. Our results are consistent with the 'activation models', showing that numerous DRs in the VCL group may be related to lighter sleep.

The combination of a smoking cessation programme with rehabilitation increases stop-smoking rate.

OBJECTIVE AND STUDY DESIGN: A parallel group study to investigate the effectiveness of a smoking cessation programme performed during routine rehabilitation practice for outpatients. PATIENTS AND METHODS: The study participants comprised an intervention group of 102 consecutive smokers who underwent a smoking cessation programme in a rehabilitation centre and a control group of 101 consecutive smokers who were referred to a smoking cessation centre in a pulmonary hospital. All participants underwent physical examination,pulmonary function tests and received identical behavioural and/or pharmacological treatment. In addition, the intervention group underwent rehabilitation practice 3 times a week for 3 months. RESULTS: The continuous abstinence rate at 12 months, which was validated by an expired air carbon monoxide concentration of 10 parts per million or less and a household interview, was 68% in the intervention group and 32% in the control group. Multivariable analysis showed that rehabilitation was significantly associated with smoking cessation after adjusting for years of smoking, number of cigarettes smoked,gender and treatment (odds ratio = 4.34, p < 0.001). CONCLUSION: This study suggests that smoking cessation programmes during routine rehabilitation may be highly effective in helping smoking withdrawal and should be a strongly recommended component of rehabilitation practice.
