[Implementation of smoking cessation in the workflow of a lung cancer screening program in Germany - A Position Paper of the German Respiratory Society (DGP)]. / Implementierung der Tabakentwöhnung in den Workflow des Lungenkrebsscreenings in Deutschland.

Both tobacco cessation and low-dose CT screening in at-risk individuals reduce lung cancer-specific and all-cause mortality. As part of a national screening program for the early detection of lung cancer, smoking cessation must be a mandatory part of the counseling given to participants. This increases the cost-benefit effectiveness of the screening program. As part of the initial consultation evidence-based measures for smoking cessation must be offered to smoking participants of the screening program in form of a minimal intervention. If participants do not want to participate in a quit smoking measure they must actively refuse (opt-out rule). The costs of quitting smoking, including the costs of withdrawal-inhibiting medication, have to be fully covered by statutory health insurance for participants in the lung cancer screening program.

[Harmful health effects of flavors in e-cigarettes]. / Gesundheitsschädliche Wirkungen von Aromen in E-Zigaretten.

BACKGROUND: Almost all e-cigarettes contain flavorings that make the product more attractive. In the evaluation of e-cigarettes on health, flavors have so far played a subordinate role. METHOD: Selective literature search in PubMed, supplemented by legal regulations on the use of flavors in e-cigarettes. RESULTS: Flavors make it easier to start using e-cigarettes and have a consumption-promoting effect. Deeper inhalation increases nicotine uptake and the absorption of toxic substances from the e-cigarette liquid. For some flavors, pathological effects have been demonstrated in addition to other toxic components of the e-cigarette. To date, no toxicological analyses are available for the vast majority of flavors contained in e-cigarettes. CONCLUSIONS: The proven consumption-promoting effect and the health risks that can be extrapolated from preclinical data are significant for the political discussion of a ban on flavors for e-cigarettes, analogous to the ban on flavors in tobacco products already in force.

[Tobacco cessation - the underused potential in clinical routine]. / Tabakentwöhnung ­ die bisher wenig genutzte Chance im ärztlichen Alltag.

Tobacco control, psychosocial and medical assistance regarding tobacco cessation is still a hidden potential within the German health care system. So far doctors rarely talk to their patients about their smoking status and physical and psychological benefits of quitting.This paper focusses on recommended current diagnostic and treatment standards, as well as evidence-based methods to address the topic on how to stop smoking and its association with certain diseases such as COPD, lung cancer and COVID-19 infection. The role of e-cigarettes as a cessation tool and its health related risks are critically examined. Consequences and advice how to implement smoking cessation procedures into daily practice are presented.

[Medical societies in Germany call for a ban on flavors in e-cigarettes - A Position Paper of the German Respiratory Society (DGP) in cooperation with other professional associations and organizations]. / Medizinische Fachgesellschaften fordern ein Verbot von Aromen in E-Zigaretten.

E-cigarettes are primarily used by teenagers and young adults. Flavors in e-cigarettes increase their attractiveness and encourage young people and adults to start using them. This exposes young people in particular to the risk of nicotine addiction and various toxic substances from the aerosol of e-cigarettes. There are indications that various flavors in e-cigarettes are harmful to health, although toxicological studies are still lacking for the majority of flavors. There is a need for independent scientific investigations in this area. The scientific societies involved are calling for a ban on flavors in e-cigarettes, a ban on disposable e-cigarettes, effective regulation of the sale of e-cigarettes and effective control and implementation of the provisions for the protection of minors.

The process of implementing early detection of lung cancer with low-dose CT (LDCT) in Germany has gained significant momentum in recent years. It is expected that the ordinance of the Federal Ministry for the Environment, Nature Conservation, Nuclear Safety and Consumer Protection (BMUV) on the early detection of lung cancer, which has been commented on by the professional societies, will come into effect by the end of 2023. Based on this regulation, the Federal Joint Committee (G-BA) will set up a program for early lung cancer detection with LDCT in the near future. In this position paper, the specialist societies involved in lung cancer screening present key points for a uniform, structured and quality-assured early detection program for lung cancer in Germany to make a constructive contribution to this process.

[The e-cigarette - means of smoking cessation?] / Die E-Zigarette ­ Mittel zur Tabakentwöhnung?

After several years of declining tobacco consumption, the number of smokers in Germany is currently stagnating or rising again. The reasons seem to be manifold, e. g. stress caused by the pandemic with social isolation, rising cost of living and war in Europe.With tobacco use still widespread in the German population, evidence-based tobacco cessation is rarely implemented.According to recent studies, e-cigarettes are involved in the pathogenesis of lung disease, cardiac and vascular damage. In addition, their ingredients also have carcinogenic effects. However, clinical studies on long-term use are not yet available.E-cigarettes as a consumer product are not superior to nicotine replacement products and addiction-reducing medications recommended in guidelines. In the therapeutic setting, they are slightly more effective than nicotine replacement products. However, they are usually consumed continuously and thus perpetuate nicotine dependence. Their use increases the risk of relapse to tobacco smoking.Despite the various new approaches, such as Internet-based offerings, app, etc., talks and pharmacotherapy are the gold standard and more effective than any therapy on its own.

[Smoking cessation - achievable and effective]. / Tabakentwöhnung ­ wirksam und kosteneffektiv.

In hospital, effective smoking cessation can be organized through counselling, pharmacological aids and, above all, continuous care in outpatient structures following discharge. Pharmacological treatment has proven to be effective and safe with nicotine replacement therapy as well as varenicline. Counselling plus pharmacotherapy is more effective in combination than either therapy is on its own. To better implement structures medical societies in Germany are seeking adequate funding e. g. in the DRG system for hospitalised patients.There are obvious and relevant benefits in smoking cessation. Not only for the main tobacco-related diseases such as coronary heart disease or chronic obstructive pulmonary disease (COPD), positive effects of quitting on morbidity and mortality have been confirmed by high-quality meta-analyses. Furthermore, quality of life is increasing following cessation. Presently, smoking is found to be a significant risk factor for severe disease and mortality following coronavirus infection.Do e-cigarettes offer an alternative in smoking cessation? No. Animal and human data are suggesting toxic effects especially following longer use. The long-term effectiveness of e-cigarettes in tobacco cessation is still uncertain and epidemiologic data clearly point toward ineffectiveness. Furthermore, dual use with potentiation of the toxic effects is common. Therefore, e-cigarettes cannot be recommended for tobacco cessation.

[COVID-19 and Smoking - A Position Paper by the DGP Taskforce for Smoking Cessation]. / COVID-19 und Rauchen.

Tobacco smoking is associated with severe health risks. In 2020, the WHO estimated that 8 million people have died due to smoking. Furthermore, smoking tobacco is a well-known risk factor for various infectious pulmonary diseases. The question raised, whether smoking is facilitating SARS-CoV-2-infections and increases adverse outcomes of COVID-19. To answer these questions a narrative review was conducted, finally including 7 systematic reviews with meta-analyses published in January and February 2021. Tobacco smoking was associated with an increased COVID-19 disease severity (odds ratio range of active vs. never smokers 1.55-2.19 and former vs. never smokers 1.20-2.48) and an increased COVID-19 in-hospital mortality (odds ratio range of active vs. never smokers 1.35-1.51 and former vs. never smokers 1.26-2.58). Beside immediate pulmonary toxic effects through active smoking, the cumulative livelong tobacco exposition and subsequent tobacco-associated diseases seem to predominantly predict adverse outcomes in patients with COVID-19. Data regarding an increased risk of infection among smokers is conflicting. However, a large observational study from England with 2.4 million persons reported an association between tobacco smoking and typical symptoms of COVID-19. For e-cigarettes and vaping less data exist, but experimental and first clinical investigations also suggest an increased risk for adverse outcomes for their use and SARS-CoV-2 infections. Especially during the current SARS-CoV-2 pandemic with limited therapeutic options it is particularly important to advise smokers of their increased risks for unfavourable COVID-19 outcomes. Evidence based support for smoking cessation should be offered. In Germany, the existing and well-established methods to support tobacco cessation need to be reimbursed by statutory health insurances.

Evaluation of long-term quitters: who stays smoke free forever?

BACKGROUND: Smoking cessation is one of the most powerful health promotion tools in the Western world. Behavioral group therapies are regarded as very promising interventions in this field. Quitting rates are usually evaluated after 6-12 months and lie between 30 and 45%. So far, there are no scientific data on potential protective indicators to remain successfully smoke free after this period. Therefore, the aim of this study was to detect the current smoking status of former participants of a cessation service in an urban German surrounding. We investigated reasons for relapses, quitting strategies, and psychosocial parameters. METHODS: In 2019, 130 former patients (2011-2017; mean age 54 years; 37 pack/years; Fagerstroem = 5.75; 58.5% male, 41.5% female; 66% physical comorbidities; 35% psychiatric diagnoses) were invited to participate in a mailed survey (including WHO 5, SF 12, self-efficacy scale) and were asked about their current smoking status, personal history of smoking, and individual experiences with stopping after the 1­year abstinence date. RESULTS: A total of 53 persons replied (RR 41%), 29 (54%) of whom are currently smoke free; 24 relapsed intermittently or permanently, 9 experimented with e­cigarettes, and 2 became dual users. Daily hassles as well as physical and mental challenges were the main reasons for relapsing. CONCLUSION: Due to the low response rate, conclusions are limited; however, the 1­year abstinence rate might not be as reliable as thought so far; long-term "sober" nicotine addicts remain at risk of relapse.

Increased vulnerability of COPD patient groups to urban climate in view of global warming.

PURPOSE: Patients with COPD show an increase in acute exacerbations (AECOPD) during the cold season as well as during heat waves in the summer months. Due to global climate changes, extreme weather conditions are likely to occur more frequently in the future. The goal of this study was to identify patient groups most at risk of exacerbations during the four seasons of the year and to determine at which temperature threshold the daily hospital admissions due to AECOPD increase during the summer. PATIENTS AND METHODS: We analyzed retrospective demographic and medical data of 990 patients, who were hospitalized for AECOPD in Berlin, Germany. The cases were grouped into the following cohorts: "spring" (admission between March and May), "summer" (June - August), "autumn" (September - November), and "winter" (December - February). AECOPD hospital admissions from 2006 and 2010 were grouped into a "hot summer" cohort and cases from 2011 and 2012 into a "cold summer" data-set. Climate data were obtained from the German Meteorological Office. RESULTS: Patients hospitalized for a COPD exacerbation during winter were significantly older than summertime patients (P=0.040) and also thinner than patients exacerbating in spring (P=0.042). COPD exacerbations during hot summer periods happened more often to patients with a history of myocardial infarction (P=0.014) or active smokers (P=0.011). An AECOPD during colder summers occurred in patients with a higher Charlson index, who suffered in increased numbers from peripheral vascular diseases (P=0.016) or tumors (P=0.004). Summertime hospital admissions increased above a daily minimum temperature of 18.3°C (P=0.006). CONCLUSION: The identification of COPD patient groups most at risk for climate related exacerbations enables climate-adapted prevention through patient guidance and treatment. In view of global climate changes, discovering vulnerabilities and implementing adaptive measures will be of growing importance.

The diagnosis of chronic obstructive pulmonary disease.

BACKGROUND: Estimates of the prevalence of chronic obstructive pulmonary disease (COPD) in Germany range from 1.9% to 13.2%, depending on the population studied and the investigative methods used. About 30% of all patients already have severe airway obstruction by the time the condition is diagnosed. METHODS: Review of pertinent literature retrieved by a selective search, including current guidelines and textbooks. RESULTS: Smoking is the main risk factor for COPD. The diagnosis is based on characteristic symptoms that patients at risk should be actively asked about-cough, dyspnea, diminished physical reserve, and frequent airway infections-together with abnormal pulmonary function tests. Spirometry usually suffices to document impaired air flow. The clinical evaluation and the treatment strategy are based on the severity of airway obstruction and dyspnea, and the frequency of exacerbations. According to a European study, dyspnea is present in 73% of persons with severe COPD, expectoration in 64%, cough in 59%, and wheezing in 42%. Asthma, congestive heart failure, and interstitial lung disease are the main differential diagnoses. CONCLUSION: COPD may begin with symptoms that are only mild at first even in a longstanding smoker. The available diagnostic techniques need better prospective validation with respect to relevant endpoints, including mortality, symptom progression, quality of life, and frequency of exacerbations.

Smoking behaviour and attitudes among German nursing students.

Tobacco consumption is a major public health threat. Healthcare workers can contribute to the reduction of tobacco use. The principles of intervention need to be provided already during vocational school. This research examines the smoking habits, the personal attitudes towards smoking and the professional beliefs of healthcare trainees. The aim of this study is to ascertain the necessity and the general conditions for multilevel interventions of prevention and health promotion. In 2010, a questionnaire survey was conducted in a Berlin vocational school for healthcare workers. Of 148 students (RR = 49.3%) 41.9% of the students are daily or occasional smokers. The nicotine dependency and the number of cigarettes per day are comparatively low. The majority of smoking students is willing to quit and has already undertaken several attempts. Non-smoking protection is evaluated to be very important and intervention rates in patient care range between 49% and 72%. In both questions, non-smokers and smokers differ significantly. The self-reported smoking prevalence in our population is considerably lower than in previous studies. However, the smoking rate among healthcare trainees is still higher than in the general population. The students' own smoking behaviours and its influences on the treatment of patients should be reflected during school. It is necessary to develop adequate recruitment strategies and attractive interventions for this target group.

Specificity of a whole blood IGRA in German nursing students.

BACKGROUND: Interferon-gamma release assays (IGRA) are used for tuberculosis (TB) screening in healthcare workers (HCWs). However, data on specificity of IGRA in serial testing of HCWs is sparse. Therefore the specificity and the negative predictive value of the IGRA - QuantiFERON-TB Gold In-Tube (QFT) - in German nursing students was investigated. METHODS: 194 nursing students at the start of their professional career were tested with the QFT. 14 nursing students were excluded from the specificity analysis, due to exposure to mycobacterium tuberculosis. Two of these subjects were QFT- positive. None of them developed disease during the year of follow-up. A study group of 180 students, all with very low risk of prior TB infection, remained in the specificity analysis. Subjects were monitored for at least two years with respect to the development of active TB disease. IGRA was performed at the start of the training and after one year. RESULTS: The mean age of the study group (n = 180) was 23 years (range 18-53) with 70.9% female and 99.4% German born. The specificity of QFT was 98.9% (178/180; 95% CI 0.96-0.99); lowering the cut-off from 0.35 IU/ml to 0.1 IU/ml would have decreased specificity only slightly to 97.8% (176/180; 95% CI 0.94-0.99). Of the 154 nursing students available for re-testing, one student who initially scored positive reverted to negative, and one student initially negative converted to positive. None of the monitored group with initially negative QFT results developed TB disease, indicating a high negative predictive value of the IGRA in this population. CONCLUSIONS: Following our data, QFT can serve as an effective tool in pre-employment TB screenings for HCWs. As its negative results were stable over time, specificity of the QFT in serial testing of HCWs is high. As the risk of acquiring TB infection in the German healthcare system appears to be low, our data supports the recommendation of performing TB screening only in those HCWs with known contact to TB patients or infectious materials.
