[Group Training of Patients with Chronic Lung Diseases under Outpatient Conditions - Recommendations of the Working Group Lung Sports in Germany and the German Airways League]. / Ambulanter Lungensport und körperliches Training bei Patienten mit Atemwegs- und Lungenkrankheiten.

To improve acceptance and use of physical training by patients with chronic lung diseases, recommendations for performing lung exercises on an outpatient basis in a group setting are given by experts in physical training, sports therapists and pulmonologists. The evidence-based positive effects of physical training were analyzed for asthma , COPD, interstitial lung diseases, cystic fibrosis, lung carcinoma, and pulmonary hypertension. The requirements for lung exercises in outpatient groups as well as compensation by care providers were given on the basis of legal regulations. Furthermore, the main items of the training units as well as supervision by specially trained group leaders in relation to the severity of the underlying lung disease are described. Finally, aspects of safety of the participating patients are discussed, including the prevention of infection with corona-2-virus.

[Relevance of Outpatient, Equipment-based Exercise Training in Patients with Chronic Respiratory Diseases]. / Stellenwert ambulanter, gerätegestützter Trainingstherapie bei Atemwegs- und Lungenkrankheiten.

Exercise training is one of the most important components in disease management for patients with chronic respiratory diseases. The clinically relevant benefits of endurance and strength training on dyspnea, exercise capacity and quality of life have been evaluated very well. However, there are some legal limitations by the German Working Group for Rehabilitation (BAR) concerning outpatient exercise training programs (beyond pulmonary rehabilitation): only group-based callisthenic training programs receive funding from health care insurances while professional equipment-based training programs are excluded despite their outstanding effectiveness.This review provides an overview on the methodology and the benefits of outpatient exercise training programs for patients with chronic respiratory diseases, and it critically discusses the organizational structures of these programs in Germany.

[Respiratory Muscle Training: State of the Art]. / Atemmuskeltraining: State-of-the-Art.

Specific respiratory muscle training (IMT) improves the function of the inspiratory muscles. According to literature and clinical experience, there are 3 established methods: 1.) resistive load 2.) threshold load and 3.) normocapnic hyperpnea. Each training method and the associated devices have specific characteristics. Setting up an IMT should start with specific diagnostics of respiratory muscle function and be followed by detailed individual introduction to training. The aim of this review is to take a closer look at the different training methods for the most relevant indications and to discuss these results in the context of current literature. The group of neuromuscular diseases includes muscular dystrophy, spinal muscular atrophy, amyotrophic lateral sclerosis, paralysis of the phrenic nerve, and injuries to the spinal cord. Furthermore, interstitial lung diseases, sarcoidosis, left ventricular heart failure, pulmonary arterial hypertension (PAH), kyphoscoliosis and obesity are also discussed in this context. COPD, asthma, cystic fibrosis (CF) and non-CF-bronchiectasis are among the group of obstructive lung diseases. Last but not least, we summarize current knowledge on weaning from respirator in the context of physical activity.

[Benefits of a multimodular outpatient training program for patients with COPD]. / Effekte eines multimodularen ambulanten Trainingsprogramms für Patienten mit COPD.

BACKGROUND: The partition and chronological sequence of the different training items and modalities necessary for an effective training of patients with chronic obstructive pulmonary disease (COPD) remains a subject of debate. We investigated the combination of effective components of pulmonary rehabilitation in the settings outpatient lung sports group, home-based training and training in a gym. METHODS: Subjects were randomized to a 12-month training program and a no training group. PATIENTS AND MAIN RESULTS: The training group (n = 10, mean age: 62.5 years, FEV1 53.4% predicted) reached an average increase in peakVO2 of 10% (p = 0.01) from 1.30 +/- 0.41 L/minute to 1.44 +/- 0.38 L/minute, in peak work rate of 14% (p = 0.007) from 82 +/- 39 W to 93 +/- 43 W and in the six-minute walking distance of 79 meters (p = 0.003), whereas in the control group (n = 9, mean age: 63.2 years, FEV1 53.7% predicted) no significant changes were observed. The quality of life obtained by use of the SF36-questionnaire and SGRQ also significantly improved in the training group, but not in the control group. CONCLUSION: This outpatient rehabilitation program is effective and appropriate for long-term rehabilitation of patients with COPD.

[Recommendations for planning and realisation of exercise training in outpatient lung sports groups]. / Empfehlungen zur Planung und Durchführung des körperlichen Trainings im Lungensport.

Asthma and COPD are common diseases inducing high costs. In national and international guidelines exercise training is stated as the main component amongst the nonmedical treatment options. With exercise training beneficial effects in exercise performance, quality of life and health-related costs can be obtained. Options for exercise training all over the country should be established. Therefore not only inpatient, but also outpatient structures, especially lung sports groups have to be organized to enable a continuous training. For this special way of long term training no systematic guidelines do exist. Further aggravating factors are the different basic vocational education of the trainers and the heterogeneity of the participants. The intention of the authors was to develop recommendations for a structured training and training sensitive to the target group. The realisation of training with this approach should approximate training to evidence based knowledge and contribute to the quality of training patients with lung diseases.

ComP, a pilin-like protein essential for natural competence in Acinetobacter sp. Strain BD413: regulation, modification, and cellular localization.

We recently identified a pilin-like competence factor, ComP, which is essential for natural transformation of the gram-negative soil bacterium Acinetobacter sp. strain BD413. Here we demonstrate that transcription and synthesis of the pilin-like competence factor ComP are maximal in the late stationary growth phase, whereas competence is induced immediately after inoculation of a stationary-phase culture into fresh medium. Western blot analyses revealed three forms of ComP, one with an apparent molecular mass of 15 kDa, which correlates with the molecular mass deduced from the DNA sequence, one 20-kDa form, which was found to be glycosylated, and one 23-kDa form. The glycosylation of ComP was not required for its function in DNA binding and uptake. The 20-kDa form was present in the cytoplasmic membrane, the periplasm, and the outer membrane, whereas the 23-kDa form was located in the outer membrane and might be due to a further modification. Immunological data suggest that ComP is not a subunit of the pilus structures. Possible functions of ComP in the DNA transformation machinery of Acinetobacter sp. strain BD413 are discussed.
