[Linguistic Validation of the "German Lung Fibrosis Health Related Quality of Life Questionnaire"]. / Sprachliche Validierung des Fibrose-Fragebogens zur Erfassung der Lebensqualität bei Patienten mit idiopathischer Lungenfibrose und idiopathischer nichtspezifischer interstitieller Pneumonie.

Health status and quality of life are impaired in patients with idiopathic pulmonary fibrosis (IPF) and idiopathic non-specific interstitial fibrosis (iNSIP). In Germany exists only the K-BILD questionnaire for patients with ILD 1 in a professional translation by Kreuter et al. 2 This questionnaire focuses on the main problems in patients with progressive lung fibrosis in a limited manner. Therefore a new quality of life questionnaire for patients with idiopathic pulmonary fibrosis was developed and linguistically validated. METHODS: The linguistic validation of our questionnaire was carried out in a multistage process in collaboration with the developer of the questionnaire and bilingual, professional translators. Review by the developers and back translations as well as clinical assessment by IPF- and iNSIP-patients ensured that the translated questionnaire reflected the intention of the original English version of our questionnaire.Cross-validation was carried out with the St. Georges Respiratory Questionnaire (SGRQ). RESULTS: The new questionnaire concerning the health status was composed in English and German language. The questions cover five scales (sensitivity, selectivity and symptoms like breathlessness and cough and a visual analog scale on general health status) with 23 items. CONCLUSIONS: The results show that the FFB maps the special needs of the patients with IPF and iNSIP well and can support clinical and scientific questions and can be helpful in monitoring the clinical course.

[German Guideline for Idiopathic Pulmonary Fibrosis]. / S2K-Leitlinie zur Diagnostik der idiopathischen Lungenfibrose.

Idiopathic pulmonary fibrosis (IPF) is a severe and often fatal disease. Diagnosis of IPF requires considerable expertise and experience. Since publication of the international IPF guideline in the year 2011 and Update 2018 several studies and technical advances occurred, which made a new assessment of the diagnostic process mandatory. In view of the antifibrotic drugs which have been approved for the treatment of IPF patients, the goal of this guideline is to foster early, confident and effective diagnosis of IPF. The guideline focusses on the typical clinical setting of an IPF patient and provides tools to exclude known causes of interstitial lung disease including standardised questionnaires, serologic testing and cellular analysis of bronchoalveolar lavage. High resolution computed tomography remains crucial in the diagnostic work-up. If it is necessary to obtain specimen for histology transbronchial lung cryobiopsy is the primary approach, while surgical lung biopsy is reserved for patients who are fit for it and in whom bronchoscopic diagnosis did not provide the information needed. Despite considerable progress, IPF remains a diagnosis of exclusion and multidisciplinary discussion remains the golden standard of diagnosis.

Cessation and reduction in smoking behavior: impact of creating a smoke-free home on smokers.

The aim of this study was to assess the effect of a creating a smoke-free home (SFH) on cessation and reduction of cigarette smoking on low-income smokers. This secondary data analysis uses data from study participants who were originally recruited through 2-1-1 information and referral call centers in Atlanta (Georgia, 2013), North Carolina (2014) and the Texas Gulf Coast (2015) across three randomized controlled trials testing an intervention aimed at creating SFHs, pooling data from 941 smokers. Participants who reported adopting a SFH were more likely to report quitting smoking than those who did not adopt a SFH. This was true at 3-month follow-up and even more pronounced at 6-month follow-up and persisted when considering only those who consistently reported no smoking at 3 and 6 months. Among those who did not stop smoking, the number of cigarettes per day declined significantly more and quit attempts were more frequent for those who created a SFH compared with those who did not. Findings suggest that creating a SFH facilitates cessation, reduces cigarette consumption and increases quit attempts. Future studies should assess the long-term impact of SFHs on sustaining cessation.

[DGP Interstitial Lung Disease Patient Questionnaire]. / Patientenfragebogen zur Erfassung der Ursachen interstitieller und seltener Lungenerkrankungen ­ klinische Sektion der DGP.

BACKGROUND: Interstitial lung diseases (ILD) encompass different heterogeneous, mainly chronic diseases of the pulmonary interstitium and/or alveoli with known and unknown reasons. The diagnostic of ILD is challenging and should be performed interdisciplinary. The medical history is of major importance and therefore, in German-speaking countries the Frankfurter Bogen (published in 1985) was utilised to scrutinise the medical history of the patient. This by now more than 30-years-old questionnaire requires a revision with regard to content and language. METHOD: Under the auspices of the clinical section of the DGP the new Interstitial Lung Disease Patient Questionnaire was developed in collaboration amongst pulmonologist, occupational medicine physicians and psychologists and supported by patient support groups. The questionnaire was finally optimised linguistically with the help of patients. RESULTS: The newly developed patient questionnaire for interstitial and rare lung diseases encompasses different domains: initial and current symptoms, medical history questions including prior drug treatments, previous pulmonary and extrapulmonary diseases, potential exposition at home, work and leisure time as well as family history and travelling. CONCLUSION: The newly developed questionnaire can facilitate the diagnosis in patients with suspicion on interstitial lung disease in clinical routine.

Evaluation of an online training for improving self-reported evidence-based decision-making skills in cancer control among public health professionals.

OBJECTIVES: The purpose of this evaluation was to assess the effect of the online evidence-based cancer control (EBCC) training on improving the self-reported evidence-based decision-making (EBDM) skills in cancer control among Nebraska public health professionals. STUDY DESIGN: Cross-sectional group comparison. METHODS: Previously developed EBDM measures were administered via online surveys to 201 public health professionals at baseline (comparison group) and 123 professionals who took part in the training. Respondents rated the importance of and their skill level in 18 EBCC skills. Differences were examined using analysis of variance models adjusted for gender, age, years at agency, and years in position, and stratified by respondent educational attainment. RESULTS: Among professionals without an advanced degree, training participants reported higher overall skill scores (P = .016) than the baseline non-participant group, primarily driven by differences in the partnerships and collaboration and evaluation domains. No differences in importance ratings were observed. Among professionals with advanced degrees, there were no differences in skill scores and small differences in importance scores in the expected direction (P < .05). Respondents at baseline rated the following facilitators for EBDM as important: expectations from agency leaders and community partners, high priority placed on EBDM by leadership, trainings, and positive feedback. They also reported using a variety of materials for making decisions about programs and policies, though few used individual scientific studies. CONCLUSIONS: EBCC led to improved self-reported EBDM skills among public health professionals without an advanced degree, though a gap remained between the self-reported skills and the perceived importance of the skills. Further research on training content and modalities for professionals with higher educational attainment and baseline skill scores is needed.

[Expert Knowledge and Supporting Advice for the Clinical Use of Nintedanib in Patients with Idiopathic Pulmonary Fibrosis]. / Erfahrungen und unterstützende Hinweise zur Anwendung von Nintedanib bei Patienten mit idiopathischer Lungenfibrose.

In October 2016, a group of German IPF experts were invited by Boehringer Ingelheim to meet in Frankfurt with the aim, (a) to discuss relevant aspects of the management and treatment of idiopathic pulmonary fibrosis (IPF) using nintedanib; and, (b) to provide supportive advice for daily clinical practice with nintedanib. The resulting information compiled in this document is confined to practical issues regarding the use of nintedanib in patients with IPF. Where different therapeutic options were available, the choice of IPF medication was not discussed and the experts alluded to current guidelines for the diagnosis and treatment of IPF.The participants discussed a comprehensive spectrum of clinical questions related to 10 different topics, including patient-related aspects at initiation of IPF therapy, the treatment of anticoagulated IPF patients, and the handling of nintedanib-related adverse events such as gastrointestinal side effects and elevated liver enzymes. In addition, the experts evaluated therapeutic options for IPF patients with continuous disease progression, clinical scenarios that justify discontinuation of nintedanib treatment, and therapeutic options for IPF patients with an acute exacerbation or severe infection. Finally, the participants discussed the handling of nintendanib before/after elective surgical intervention (e. g. lung transplantation) and the current evidence for antifibrotic combination therapy in patients with IPF.For each topic discussed, the resulting information incorporates published evidence from clinical trials. In case of insufficient or lacking evidence, the experts have formulated recommendations based on their personal clinical experience and evaluation.

[Pulmonary manifestations in collagen vascular diseases]. / Pulmonale Manifestationen bei Kollagenosen.

CLINICAL/METHODICAL ISSUE: Pulmonary complications are frequent in patients with collagen vascular diseases (CVD). Frequent causes are a direct manifestation of the underlying disease, side effects of specific medications and lung infections. STANDARD RADIOLOGICAL METHODS: The standard radiological procedure for the work-up of pulmonary pathologies in patients with CVD is multidetector computed tomography (MDCT) with thin-slice high-resolution reconstruction. PERFORMANCE: The accuracy of thin-slice CT for the identification of particular disease patterns is very high. The pattern of usual interstitial pneumonia (UIP) representing the direct pulmonary manifestation of rheumatoid arthritis (RA) can be identified with a sensitivity of 45 % and a specificity of 96 %. ACHIEVEMENTS: Both direct pulmonary manifestations, drug-induced toxicity and certain infections can have a similar appearance in thin-slice MDCT in various forms of CVD. Knowledge of the patterns and causes contributes to the diagnostic certainty. PRACTICAL RECOMMENDATIONS: At first diagnosis of a CVD and associated pulmonary symptoms thin-slice MDCT is recommended. Clinical, lung function and imaging follow-up examinations should be performed every 6-12 months depending on the results of the MDCT. In every case the individual CT morphological patterns of pulmonary involvement must be identified. The combination of information on the anamnesis, clinical and imaging results is a prerequisite for an appropriate disease management.

[Pulmonary granulomatous diseases and pulmonary manifestations of systemic granulomatous disease : Including tuberculosis and nontuberculous mycobacteriosis]. / Pulmonale granulomatöse Erkrankungen und pulmonale Manifestationen systemischer Granulomatosen : Inklusive Tuberkulose und nichttuberkulöse Mykobakteriosen.

CLINICAL/METHODICAL ISSUE: Granulomas as signs of specific inflammation of the lungs are found in various diseases with pulmonary manifestations and represent an important imaging finding. STANDARD RADIOLOGICAL METHODS: The standard imaging modality for the work-up of granulomatous diseases of the lungs is most often thin-slice computed tomography (CT). There are a few instances, e. g. tuberculosis, sarcoidosis and silicosis, where a chest radiograph still plays an important role. METHODICAL INNOVATIONS: Further radiological modalities are usually not needed in the routine work-up of granulomatous diseases of the chest. In special cases magnetic resonance imaging (MRI) and positron emission tomography (PET)-CT scans play an important role, e. g. detecting cardiac sarcoidosis by cardiac MRI or choline C­11 PET-CT in diagnosing lung carcinoma in scar tissue after tuberculosis. PERFORMANCE: The accuracy of thin-slice CT is very high for granulomatous diseases. ACHIEVEMENTS: In cases of chronic disease and fibrotic interstitial lung disease it is important to perform thin-slice CT in order to diagnose a specific disease pattern. Thin-slice CT is also highly sensitive in detecting disease complications and comorbidities, such as malignancies. Given these indications thin-slice CT is generally accepted in the routine daily practice. PRACTICAL RECOMMENDATIONS: A thin-slice CT and an interdisciplinary discussion are recommended in many cases with a suspected diagnosis of pulmonary granulomatous disease due to clinical or radiographic findings.

[Imaging and Laboratory Diagnostics for Tuberculosis]. / Bildgebung und Labordiagnostik bei Tuberkulose.

Diagnosis of tuberculosis (TB) is difficult, since symptoms are often very unspecific or lacking. However active, prompt and accurate diagnosis is the key element in the public health response to tuberculosis and the cornerstone of tuberculosis control. Different diagnostic methods for an assured diagnosis of TB are necessary. Chest radiography is a useful keystone to identify tuberculosis, but diagnosis of tuberculosis cannot be established by radiography alone. CT scanning is used in patients without pathological chest radiography but clinically suspected active TB and to differentiate TB from other diseases. Radiological appearance is primarily determined by the immune status of patients and caverns and disseminated disease foci are often observed. Laboratory diagnostic methods include microscopic identification of acid-fast mycobacteria from any body fluid (especially sputum), as well as isolation and characterisation of mycobacteria in culture. It is then possible to type the pathogens by the shape of their colony, their growth behavior and their biochemical characteristics. These methods are regarded as the gold standard in diagnosis of active TB. In patients who are highly suspected of having TB, but whose sputum specimens tested negative for mycobacteria, a nucleic acid amplification test is additionally performed. Moreover, sensitivity testing with first and second line antitubercular drugs is applied as standard. Laboratory diagnostic testing of cellular immunity against pathogenic mycobacteria employs the tuberculin skin test (TST, Mantoux tuberculin test) or the more specific interferon γ test to determine γ interferon released by T lymphocytes stimulated in vitro. The new ELISA and ELISPOT procedures exhibit higher test specificity and less cross reactivity to NTM (non-tuberculosis mycobacteria), are independent of BCG-vaccination status and correlate better with the degree of exposure than does the TST.

[German Validation of the "King's Brief Interstitial Lung Disease (K-Bild) Health Status Questionnaire"]. / Deutschsprachige Validierung des "Kingʼs Brief Interstitial Lung Disease (K-BILD)" Lebensqualitätsfragebogens für interstitielle Lungenerkrankungen.

Background: Health status and quality of life are impaired in patients with interstitial lung disease (ILD). To assess these parameters in ILD patients no valid and reliable questionnaire exists in German language so far. The K-BILD questionnaire is a brief and valid tool to evaluate health status in ILD patients, with no validated German version. Method: The linguistic validation of K-BILD was carried out in a multistage process in collaboration with the developer of the questionnaire and bilingual, professional translators. Review by the developers and back translations as well as clinical assessment by ILD patients ensured that the translated questionnaire reflected the intention of the original K-BILD. Results: A German version of K-BILD with 15 questions concerning the health status was composed. The questions cover the three domains breathlessness and activities, psychological aspects and chest symptoms. Problems in understanding or difficulties in replying to the questions were not stated by the ILD patients. Conclusion: The German version of the K-BILD questionnaire allows the clinical and scientific use to measure reliable health quality in ILD patients.

[Cannabis--Position Paper of the German Respiratory Society (DGP)]. / Cannabis--Positionspapier der Deutschen Gesellschaft für Pneumologie und Beatmungsmedizin e.V. (DGP).

In this position paper, the adverse health effects of cannabis are reviewed based on the existing scientific literature; in addition possible symptom-relieving effects on some diseases are depicted. In Germany, cannabis is the most widely used illicit drug. Approximately 600,000 adult persons show abusive or addictive cannabis consumption. In 12 to 17 year old adolescents, cannabis use increased from 2011 to 2014 from 2.8 to 6.4%, and the frequency of regular use from 0.2 to 1.5%. Currently, handling of cannabinoids is much debated in politics as well as in general public. Health aspects have to be incorporated into this debate. Besides analysing mental and neurological side effects, this position paper will mainly focus on the influences on the bronchopulmonary and cardiovascular system. There is strong evidence for the induction of chronic bronchitis. Allergic reactions including asthma are known, too. Associations with other diseases like pulmonary emphysema, lung cancer and pneumonia are not sufficiently proven, however cannot be excluded either. In connection with the use of cannabis cardiovascular events such as coronary syndromes, peripheral vascular diseases and cerebral complications have been noted. Often, the evidence is insufficient due to various reasons; most notably, the overlapping effects of tobacco and cannabis use can frequently not be separated adequately. Empirically, early beginning, high-dosed, long-lasting and regular cannabis consumption increase the risk of various psychological and physical impairments and negatively affect age-based development. Concerns therefore relate especially to children and adolescents. There is only little scientific evidence for medical benefits through cannabis as a remedy; systematic research of good quality, in particular prospective, randomised, placebo-controlled double-blinded studies are rare. The medical societies signing this position paper conclude that cannabis consumption is linked to adverse health effects which have to be taken into consideration in the debate about the social attitude towards cannabinoids. The societies agree that many aspects regarding health effects of cannabis are still uncertain and need clarification, preferably through research provided by controlled studies.

Development of targeted messages to promote smoking cessation among construction trade workers.

Blue-collar workers, particularly those in the construction trades, are more likely to smoke and have less success in quitting when compared with white-collar workers. Little is known about health communication strategies that might influence this priority population. This article describes our formative work to develop targeted messages to increase participation in an existing smoking cessation program among construction workers. Using an iterative and sequential mixed-methods approach, we explored the culture, health attitudes and smoking behaviors of unionized construction workers. We used focus group and survey data to inform message development, and applied audience segmentation methods to identify potential subgroups. Among 144 current smokers, 65% reported wanting to quit smoking in the next 6 months and only 15% had heard of a union-sponsored smoking cessation program, despite widespread advertising. We tested 12 message concepts and 26 images with the target audience to evaluate perceived relevance and effectiveness. Participants responded most favorably to messages and images that emphasized family and work, although responses varied by audience segments based on age and parental status. This study is an important step towards integrating the culture of a high-risk group into targeted messages to increase participation in smoking cessation activities.

[Position Paper: Significance of the Forced Vital Capacity in Idiopathic Pulmonary Fibrosis]. / Positionspapier zur Bedeutung der forcierten Vitalkapazität für Patienten mit idiopathischer Lungenfibrose (IPF).

Spirometry is a highly standardized method which allows to measure the forced vital capacity (FVC) with high precision and reproducibility. In patients with IPF FVC is directly linked to the disease process which is characterized by scaring of alveoli and shrinkage of the lungs. Consequently, there is ample evidence form clinical studies that the decline of FVC over time is consistently associated with mortality in IPF. As for the first time effective drugs for the treatment of IPF are available it becomes obvious that in studies which could demonstrate that the drug reduces FVC decline, a numerical effect on mortality was also observed, while in one study where a significant effect on FVC decline was missed, there was also no change in mortality. Based on these studies FVC decline is a validated surrogate of mortality in IPF. It is concluded that FVC decline is not only accepted as an endpoint of clinical treatment trials in IPF but is also valid as a patient related outcome parameter which should be considered for the assessment of the efficacy of an IPF drug.

[Respiratory therapy with Ez-PAP for treatment of dynamic hyperinflation in patients with severe COPD and emphysema]. / Atemtherapie mit Ez-PAP zur Behandlung der dynamischen Überblähung bei Patienten mit schwerer COPD und Lungenemphysem.

BACKGROUND: Non-pharmacological respiratory physiotherapy in treatment of COPD with severe emphysema is achieving increasing importance. Ez-PAP, a compact CPAP- or flow-PEP system, supports inspiration by using the Coanda effect in addition to a PE(E)P-effect during expiration. METHODS AND PATIENTS: 30 patients with severe COPD and emphysema and hypercapnic respiratory failure under non-(NIV) (n = 28) and invasive ventilation (n = 2) were treated in ventilator-free intervals with Ez-PAP and analyzed retrospectively. Clinical courses such as ventilator-dependency, dyspnea by visual CR-10 Borg scale, results of six-minute walk tests (6MWT), lung function tests and recordings of transcutaneous CO2 measurements were evaluated where possible. RESULTS: Analyzed patients showed less ventilator dependancy (n = 9), reported a median decrease of shortness of breath by 3,3 points (n = 10) and improved by 50,4 m in the 6MWT (n = 5). A median increase of vital capacity by 544 ml (n = 5) was shown by spirometry. Combined with manual techniques for reducing air-trapping, treatment success was documented by a median reduction of pCO2 by 7,3 mmHg (n = 6) using transcutaneous pCO2 measurement. CONCLUSION: Ez-PAP is a simple mechanical method to reduce dynamic hyperinflation in severe COPD, thus achieving relief of respiratory muscles and more effective breathing. Prospective studies of this promising method are urgently required.

[Smoking cessation in patients with COPD]. / Tabakentwöhnung bei COPD.

Chronic obstructive pulmonary disease (COPD) is a leading cause of death worldwide. Cigarette smoking is the main cause of COPD. Quitting smoking is thus the most effective treatment strategy and central in COPD prevention. A number of guidelines on prevention, diagnosis, therapy and rehabilitation of COPD have been published. To help implementing and standardizing smoking cessation in COPD a guideline was published 2008 in Germany focusing on this complex issue. The present guideline is an update of the 2008 guideline and has a high grade of evidence (S3 according to the AWMF; Arbeitsgemeinschaft wissenschaftlicher medizinischer Fachgesellschaften). The guideline gives comprehensive and practical information on how to integrate smoking cessation as an central part of COPD therapy.
