The prevalence of tobacco smoking in Germany is high (~27%). Monitoring of national patterns of smoking behaviour and data on the “real-world” effectiveness of cessation methods are needed to inform policies and develop campaigns aimed at reducing tobacco-related harm. In England, the Smoking Toolkit Study (STS) has been tracking such indicators since 2006, resulting in the adaptation of tobacco control policies. However, findings cannot be directly transferred into the German health policy context. The German Study on Tobacco Use (DEBRA: “Deutsche Befragung zum Rauchverhalten”) aims to provide such nationally representative data. In June 2016, the study started collecting data from computer-assisted, face-to-face household interviews in people aged 14 years and older. Over a period of 3 years, a total of ~36,000 respondents will complete the survey with a new sample of ~2000 respondents every 2 months (=18 waves). This sample will report data on demographics and the use of tobacco and electronic (e-)cigarettes. Per wave, about 500–600 people are expected to be current or recent ex-smokers (<12 months since quitting). This sample will answer detailed questions about smoking behaviour, quit attempts, exposure to health professionals’ advice on quitting, and use of cessation aids. Six-month follow-up data will be collected by telephone. The DEBRA study will be an important source of data for tobacco control policies, health strategies, and future research. The methodology is closely aligned to the STS, which will allow comparisons with data from England, a country with one of the lowest smoking prevalence rates in Europe (18%). This study has been registered at the German Clinical Trials Register ( DRKS00011322 ) on 25th November 2016.

Background: Current data on tobacco use are a necessary prerequisite for the study of the implementation of tobacco control measures in the general population. The German Study on Tobacco Use (Deutsche Befragung zum Rauchverhalten, DEBRA) provides previously lacking data on key indicators of smoking behavior and on the consumption of new products such as e-cigarettes. The continual acquisition and accumulation of data permits the analysis of trends and precise statistical evaluation. Methods: Data were obtained by repeated face-to-face interviews, at 2-month intervals, of representative samples of approximately 2000 persons across Germany aged 14 years and above. For this article, data from 12 273 persons that were acquired in 6 waves of the survey (June/July 2016 to April/May 2017) were aggregated and weighted. Results: The one-year prevalence of current tobacco consumption was 28.3% (95% confidence interval: [27.5; 29.1]) in the overall survey population and 11.9% [8.9; 14.9] among persons under age 18. Higher tobacco consumption was correlated with lower educational attainment and lower income. 28.1% of the smokers had tried to quit smoking in the past year; the most commonly used method of quitting was e-cigarettes (9.1%). Brief physician advice or pharmacotherapy for smoking cessation were tried by 6.1% and 7.0%, respectively. 1.9% of the overall survey population but only 0.3% of persons who had never smoked were current consumers of e-cigarettes. Conclusion: Tobacco consumption is very high in Germany compared to other countries in Western and Northern Europe, and its distribution across the population is markedly uneven, with a heavy influence of socioeconomic status.

Objective: Alterations in cortisol awakening and stress responses (CAR, CSR) are sensitive markers for the basal activity and responsiveness of the hypothalamus–pituitary–adrenal axis (HPAA) in psychopathological conditions. We investigated whether patients with takotsubo cardiomyopathy (TTC) differ in these markers when compared with non-ST-segment elevation myocardial infarction (NSTEMI) patients and healthy controls. Methods: 19 female TTC patients were compared with 20 female NSTEMI patients and with 20 healthy women, matched by age and index event date. Salivary sampling indicated cortisol release, questionnaires assessed personality, life events, chronic stress and psychiatric symptoms. Results: The groups did not differ relevantly in their basal HPAA activity, psychiatric or personality profiles. Despite increased heart rates in response to stress (median difference (MD_diff)=3.5, p=0.002) and higher nervousness scores (MD_diff=−3.0, p=0.024), TTC patients revealed a blunted CSR with a medium effect compared to the controls (MD_diff=−3.2 nmol/L, p=0.022, r=0.36); even when controlled for prestress cortisol differences (p=0.044, r=0.33). In comparison with NSTEMI patients, no significant differences in CSR (MD_diff=−1.9 nmol/L, p=0.127, r=0.25) or nervousness (MD_diff=2.0, p=0.107) can be observed. Stressful life events, for example, traumatic experiences, occurred more often in TTC (42%) than in NSTEMI patients and controls (both 10%, p=0.031). Conclusions: In this small exploratory trial, a trend for a blunted CSR and high incidences of stressful life events were observed in TTC patients. If these results can be confirmed in larger studies, chronic stress and the inhibitory influence of cortisol on catecholamine release might be significant for the pathogenesis of TTC.

Situation-specific theories provide nurses with a vehicle to interpret situations, guide their decisions or make assumptions about factors influencing a health problem. In this article, we used meta-synthesis techniques to integrate statements of findings pertaining to barriers and facilitators to heart failure self-care that were derived previously through meta-summary techniques leading to a new situation-specific theory. According to our proposed theory, self-care behavior is the result of a patient’s naturalistic decision-making process. This process is influenced by two key concepts: “self-efficacy” and the “patient’s disease concept of heart failure.” Numerous facilitative and inhibitive factors have been identified influencing these two key concepts as well as the decision-making process, thereby either enabling or hampering the execution of effective heart failure self-care. Further research is needed to validate the model through empirical testing. Once fully matured, the model may be useful in developing behavioral interventions aiming at enhancing adherence to self-care recommendations.
