RESUMO
On January 19, 2021, a new regulation on the mask requirement was issued in an initiative by the federal and state governments. This regulation obliges citizens to wear medical masks on public transport and in shops. In its statement, the German Society for Pneumology and Respiratory Medicine (DGP) describes the technical background of the various medical masks and explains their functionality using the associated standards. The DGP comes to the conclusion that FFP masks of the EN 149 standard were designed for the self-protection of the wearer and ensure this if the mask is worn properly and closes tightly to the face. Incorrect use must be avoided at all costs. Surgical masks in accordance with the EN 14683 standard were designed to protect against bacteria-carrying aerosols and, due to their design, have a rather low self-protection component. Community masks are not yet subject to any official standard. Community masks with electrostatic properties and high filtration performance could represent a reusable alternative in the future. Depending on the severity of their illness, patients with heart and/or lung diseases require a stress test with a mask to minimize medical risks.

BACKGROUND: Peripheral neuropathy is a common comorbidity in COPD. We aimed to investigate associations between alterations commonly found in COPD and peripheral neuropathy, with particular emphasize on the distinction between direct and indirect effects. METHODS: We used visit 4 data of the COPD cohort COSYCONET, which included indicators of polyneuropathy (repeated tuning fork and monofilament testing), excluding patients with diabetes a/o increased HbA1c. These indicators were analysed for the association with COPD characteristics, including lung function, blood gases, 6-min walk distance (6-MWD), timed-up-and-go-test (TUG), exacerbation risk according to GOLD, C-reactive protein (CRP), and ankle-brachial index (ABI). Based on the results of conventional regression analyses adjusted for age, BMI, packyears and gender, we utilized structural equation modelling (SEM) to quantify the network of direct and indirect relationships between parameters. RESULTS: 606 patients were eligible for analysis. The indices of polyneuropathy were highly correlated with each other and related to base excess (BE), ABI and TUG. ABI was linked to neuropathy and 6-MWD, exacerbations depended on FEV1, 6-MWD and CRP. The associations could be summarized into a SEM comprising polyneuropathy as a latent variable (PNP) with three measured indicator variables. Importantly, PNP was directly dependent on ABI and particularly on BE. When also including patients with diabetes and/or elevated values of HbA1c (n = 742) the SEM remained virtually the same. CONCLUSION: We identified BE and ABI as major determinants of peripheral neuropathy in patients with COPD. All other associations, particularly those with lung function and physical capacity, were indirect. These findings underline the importance of alterations of the micromilieu in COPD, in particular the degree of metabolic compensation and vascular status.

BACKGROUND: Previous studies showed controversial results for the influence of pregnancy-related and perinatal factors on subsequent respiratory and atopic diseases in children. The aim of this study was to assess the association between perinatal variables and the prevalence of asthma, bronchial hyperreactivity (BHR), flexural eczema (FE), allergic rhinitis, and sensitization in childhood and early adulthood. METHODS: The studied population was first examined in Munich and Dresden in 1995/1996 at age 9-11 years. Participants were followed until age 19-24 years using questionnaires and clinical examinations. Associations between perinatal data and subsequent atopic diseases were examined using logistic regression analyses adjusting for potential confounders. RESULTS: Cesarean section was statistically significantly associated with BHR in early adulthood (odds ratio 4.8 [95% confidence interval 1.5-15.2]), while assisted birth was associated with presence of asthma symptoms in childhood (2.2 [1.2-3.9]), FE symptoms (2.2 [1.2-4.3]) and doctor's diagnosis of atopic dermatitis (1.9 [1.0-3.4]) in childhood, and sensitization in early adulthood (2.2 [1.1-4.3]). Lower birth length (1.9 [1.1-3.2]), lower birthweight (0.5 [0.3-0.9]), and higher birthweight (0.6 [0.4-1.0]) were predictive of sensitization in early adulthood compared to average birth length and birthweight, respectively. None of the other perinatal factors showed statistically significant associations with the outcomes. CONCLUSIONS: Our results indicate that children who are born by cesarean section and especially by assisted birth, might be at greater risk for developing asthma, FE, and sensitization and should hence be monitored. Prenatal maternal stress might partly explain these associations, which should be further investigated.

The possible impact of ultrafine particles from laser printers on human health is controversially discussed although there are persons reporting substantial symptoms in relation to these emissions. A randomized, single-blinded, cross-over experimental design with two exposure conditions (high-level and low-level exposure) was conducted with 23 healthy subjects, 14 subjects with mild asthma, and 15 persons reporting symptoms associated with laser printer emissions. To separate physiological and psychological effects, a secondary physiologically based categorization of susceptibility to particle effects was used. In line with results from physiological and biochemical assessments, we found no coherent, differential, or clinically relevant effects of different exposure conditions on subjective complaints and cognitive performance in terms of attention, short-term memory, and psychomotor performance. However, results regarding the psychological characteristics of participants and their situational perception confirm differences between the participants groups: Subjects reporting symptoms associated with laser printer emissions showed a higher psychological susceptibility for adverse reactions in line with previous results on persons with multiple chemical sensitivity or idiopathic environmental intolerance. In conclusion, acute psychological and cognitive effects of laser printer emissions were small and could be attributed only to different participant groups but not to differences in exposure conditions in terms of particle number concentrations.

3D printers are increasingly run at home. Nanoparticle emissions from those printers have been reported, which raises the question whether adverse health effects from ultrafine particles (UFP) can be elicited by 3D printers. We exposed 26 healthy adults in a single-blinded, randomized, cross-over design to emissions of a desktop 3D printer using fused deposition modeling (FDM) for 1 hour (high UFP-emitting acrylonitrile butadiene styrene [ABS] vs low-emitting polylactic acid [PLA]). Before and after exposures, cytokines (IL-1ß, IL-6, TNF-α, INF-γ) and ECP in nasal secretions, exhaled nitric oxide (FeNO), urinary 8-isoprostaglandin F2α (8-iso PGF2α ), and self-reported symptoms were assessed. The exposures had no significant differential effect on 8-iso PGF2α and nasal biomarkers. However, there was a difference (P < .05) in the time course of FeNO, with higher levels after ABS exposure. Moreover, indisposition and odor nuisance were increased for ABS exposure. These data suggest that 1 hour of exposure to 3D printer emissions had no acute effect on inflammatory markers in nasal secretions and urine. The slight relative increase in FeNO after ABS printing compared to PLA might be due to eosinophilic inflammation from inhaled UFP particles. This possibility should be investigated in further studies using additional biomarkers and longer observation periods.

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.

BACKGROUND: Colonization or infection with multi-drug resistant (MDR) bacteria is considered detrimental to the outcome of neurological and neurosurgical early rehabilitation patients. METHODS: In a German multi-center study, 754 neurological early rehabilitation patients were enrolled and and reviewed in respect to MDR status, length of stay (LOS) and the following outcome variables: Barthel Index (BI), Early Rehabilitation Index (ERI), Glasgow Outcome Score Extended (GOSE), Coma Remission Scale (CRS), Functional Ambulation Categories (FAC). RESULTS: The mean age of the study population was 68.0 ± 14.8 years. Upon admission, the following prevalence for MDRs was observed: MRSA (methicillin resistant staphylococcus aureus) 7.0% (53/754), ESBL- (extended spectrum beta-lactamase) producing bacteria strains 12.6% (95/754), VRE (vancomycin resistant enterococci) 2.8% (21/754). Patients colonized or infected with MDR bacteria (MDR+) were significantly more frequently diagnosed with a critical illness polyneuropathy - CIP - than non-colonized (MDR-) patients: 29.0% vs. 14.8%. In addition, they were more frequently mechanically ventilated (MDR+: 55/138, 39.9%; MDR- 137/616, 22.2%). MDR+ patients were referred to rehabilitation earlier, had a longer LOS in early rehabilitation, lower BI on admission and at discharge, lower ERI on admission and lower CRS at discharge than MDR- patients. There was a highly significant correlation of the BI upon admission with the BI at discharge (rs = 0.492, p < 0.001). GOSE at discharge differed significantly between both groups (χ 2-test, p < 0.01). Perhaps of greatest importance, mortality among MDR+ was higher in comparison to MDR- (18.1% vs. 7.6%). CONCLUSIONS: The outcome of neurological early rehabilitation patients colonized or infected with MDR bacteria including MRSA or ESBL producing strains is significantly poorer than by non-colonized patients. There is some evidence that the poor outcome could be related to the higher morbidity and lower functional status upon admission.

Ultrafine particles emitted from laser printers are suspected to elicit adverse health effects. We performed 75-minute exposures to emissions of laser printing devices (LPDs) in a standardized, randomized, cross-over manner in 23 healthy subjects, 14 mild, stable asthmatics, and 15 persons reporting symptoms associated with LPD emissions. Low-level exposures (LLE) ranged at the particle background (3000 cm-3 ) and high-level exposures (HLE) at 100 000 cm-3 . Examinations before and after exposures included spirometry, body plethysmography, transfer factors for CO and NO (TLCO, TLNO), bronchial and alveolar NO, cytokines in serum and nasal secretions (IL-1ß, IL-5, IL-6, IL-8, GM-CSF, IFNγ, TNFα), serum ECP, and IgE. Across all participants, no statistically significant changes occurred for lung mechanics and NO. There was a decrease in volume-related TLNO that was more pronounced in HLE, but the difference to LLE was not significant. ECP and IgE increased in the same way after exposures. Nasal IL-6 showed a higher increase after LLE. There was no coherent pattern regarding the responses in the participant subgroups or single sets of variables. In conclusion, the experimental acute responses to short but very high-level LPD exposures were small and did not indicate clinically relevant effects compared to low particle number concentrations.

Aim of the study: The Prevention Act was adopted by the German Federal Parliament on 18.06.2015. The paediatric practice is an important place from which to reach out to children and teenagers and to positively influence them through targeted prevention services in their health-related behaviour. It is therefore an important setting for the implementation of the Prevention Act. Could the delegation of prevention services to qualified medical assistants promote the successful implementation of the Prevention Act? Since 2003, medical assistants have qualified as "Prevention Assistants" after completing training courses and offered support in preventive services to children and teenagers in the paediatrician's office. The aim of this study was to improve the effectiveness of the training to increase the competence of the participants, expansion of preventive services for children and teenagers in the paediatrician's office and reduction of physician workload. Methodology: Training was accompanied by ongoing evaluation; there were two extensive studies in 2009 and 2011, respectively. Between 2003 and 2006 (n=126, after 75% response rate) and in 2011 (n=119 after 24% response rate), participants were assessed with standardized questionnaires, and in the survey of 2011, their employers also were interviewed, (n=76, after 22% response rate). Results: The prevention assistants assess their learning successes as good and are able to take over delegated tasks in the paediatrician's office. The involvement of a trained prevention assistant contributed to the transformation and re-establishment of prevention offers in paediatrician's offices and reduced physician workload. 44% of physicians felt that the time saved by prevention assistant was very good or good, 80% of physicians surveyed also indicated that prevention assistants carried out preventive consultations in the doctor's office. Conclusion: In light of the paediatricians' workload and their own wishes and demands, and for a targeted implementation of the Prevention Act, it is necessary to delegate preventive services to trained personnel. It is also possible to accomplish this task. It is necessary to introduce billing numbers in the fee schedule for doctors similar to the billing numbers for dental health prophylaxis.

Prolonged weaning of patients with neurological or neurosurgery disorders is associated with specific characteristics, which are taken into account by the German Society for Neurorehabilitation (DGNR) in its own guideline. The current S2k guideline of the German Society for Pneumology and Respiratory Medicine is referred to explicitly with regard to definitions (e.g., weaning and weaning failure), weaning categories, pathophysiology of weaning failure, and general weaning strategies. In early neurological and neurosurgery rehabilitation, patients with central of respiratory regulation disturbances (e.g., cerebral stem lesions), swallowing disturbances (neurogenic dysphagia), neuromuscular problems (e.g., critical illness polyneuropathy, Guillain-Barre syndrome, paraplegia, Myasthenia gravis) and/or cognitive disturbances (e.g., disturbed consciousness and vigilance disorders, severe communication disorders), whose care during the weaning of ventilation requires, in addition to intensive medical competence, neurological or neurosurgical and neurorehabilitation expertise. In Germany, this competence is present in centers of early neurological and neurosurgery rehabilitation, as a hospital treatment. The guideline is based on a systematic search of guideline databases and MEDLINE. Consensus was established by means of a nominal group process and Delphi procedure moderated by the Association of the Scientific Medical Societies in Germany (AWMF). In the present guideline of the DGNR, the special structural and substantive characteristics of early neurological and neurosurgery rehabilitation and existing studies on weaning in early rehabilitation facilities are examined.Addressees of the guideline are neurologists, neurosurgeons, anesthesiologists, palliative physicians, speech therapists, intensive care staff, ergotherapists, physiotherapists, and neuropsychologists. In addition, this guideline is intended to provide information to specialists for physical medicine and rehabilitation (PMR), pneumologists, internists, respiratory therapists, the German Medical Service of Health Insurance Funds (MDK) and the German Association of Health Insurance Funds (MDS). The main goal of this guideline is to convey the current knowledge on the subject of "Prolonged weaning in early neurological and neurosurgery rehabilitation".

The present guideline is a new version and an update of the guideline for the diagnosis and treatment of asthma, which replaces the previous version for german speaking countries from the year 2006. The wealth of new data on the pathophysiology and the phenotypes of asthma, and the expanded spectrum of diagnostic and therapeutic options necessitated a new version and an update. This guideline presents the current, evidence-based recommendations for the diagnosis and treatment of asthma, for children and adolescents as well as for adults with asthma.

Novel ground states might be realized in honeycomb lattices with strong spin-orbit coupling. Here we study the electronic structure of α-RuCl_{3}, in which the Ru ions are in a d^{5} configuration and form a honeycomb lattice, by angle-resolved photoemission, x-ray photoemission, and electron energy loss spectroscopy supported by density functional theory and multiplet calculations. We find that α-RuCl_{3} is a Mott insulator with significant spin-orbit coupling, whose low energy electronic structure is naturally mapped onto J_{eff} states. This makes α-RuCl_{3} a promising candidate for the realization of Kitaev physics. Relevant electronic parameters such as the Hubbard energy U, the crystal field splitting 10 Dq, and the charge transfer energy Δ are evaluated.
RESUMO
BACKGROUND AND PURPOSE: Numerous studies have shown that repetitive transcranial magnetic stimulation (rTMS) over the primary motor cortex (M1) may improve motor function of the affected hand after stroke. The effects of 1 Hz rTMS applied over the contralesional dorsal premotor cortex (PMd) on hand function and cortical neurophysiology in subacute stroke were examined. METHODS: Ten subacute stroke patients with mild hand motor impairment were enrolled in a prospective, double-blind, randomized, placebo-controlled, crossover study with two intervention sessions. 1 Hz rTMS was applied over the contralesional PMd (real rTMS, 900 pulses at 110% of the motor threshold; sham rTMS, 900 pulses at 0% of the motor threshold). Tests of hand function (Jebsen-Taylor hand function test, box and block test) and neurophysiological evaluations (resting motor threshold, motor evoked potentials, cortical silent period, ipsilateral silent period) were obtained from both hands and hemispheres prior to (baseline) and after each treatment. RESULTS: Hand function tests revealed significant improvement of motor function of the affected but not of the unaffected hand after real rTMS only. Neither intervention changed the neurophysiological measures in comparison to baseline. CONCLUSION: One hertz rTMS over the contralesional PMd improves motor function of the affected hand in subacute stroke. The PMd may be a novel rTMS target to treat motor impairment after stroke.

The study examined the effects of office space occupation, psychosocial work characteristics, and environmental satisfaction on physical and mental health of office workers in small-sized and open-plan offices as well as possible underlying mechanisms. Office space occupation was characterized as number of persons per one enclosed office space. A total of 207 office employees with similar jobs in offices with different space occupation were surveyed regarding their work situation (psychosocial work characteristics, satisfaction with privacy, acoustics, and control) and health (psychosomatic complaints, irritation, mental well-being, and work ability). Binary logistic and linear regression analyses as well as bootstrapped mediation analyses were used to determine associations and underlying mechanisms. Employee health was significantly associated with all work characteristics. Psychosocial work stressors had the strongest relation to physical and mental health (OR range: 1.66-3.72). The effect of office space occupation on employee health was mediated by stressors and environmental satisfaction, but not by psychosocial work resources. As assumed by sociotechnical approaches, a higher number of persons per enclosed office space was associated with adverse health effects. However, the strongest associations were found with psychosocial work stressors. When revising office design, a holistic approach to work (re)design is needed.

PURPOSE: The aim of this pilot study was to evaluate surface contamination by platinum drugs in the environment of patients in ICUs and wards treated by hyperthermic intraperitoneal chemotherapy (HIPEC). METHODS: The monitoring included 12 HIPEC treatments from four hospitals during the following 3 days after perfusion. A total of 33 urine and 33 drainage fluids from HIPEC patients and 160 wipe samples from several surfaces (urine/drainage bags, floors, gloves) were taken during the study period. RESULTS: In urine, the highest platinum concentrations were measured on the first day after perfusion. Median platinum concentrations were 1260 ng/ml for patients after cisplatin perfusion and 11,000 ng/ml for oxaliplatin treatment. Concentrations decreased until day three to 413 ng/ml cisplatin and 529 ng/ml oxaliplatin, respectively. In drainage liquids, platinum concentrations were generally lower. Platinum concentrations from surfaces of bags and floors ranged from 0.01 to 439 pg/cm(2) (median: urine bag 2.77 pg/cm(2), drainage bag 0.22 pg/cm(2), floor left 0.14 pg/cm(2), floor right 0.24 pg/cm(2)), with the highest contamination found on the outer surface of the urine bags. Samples from nurses' protective gloves ranged between 0.03 and 12 pg/cm(2) (median: 0.2 pg/cm(2)). CONCLUSIONS: High platinum-drug concentrations in urine and drainage liquids are the main source of contamination. Therefore, safe handling of these liquids is the best way to avoid cross-contamination on surfaces in wards and ICUs. Our results show that it is possible to take care of HIPEC patients without high contaminations during the first 3 days.

Up to a third of dermatology outpatients have a significant psychiatric issue complicating their skin complaint. Although the ideal would frequently involve psychiatric assessment, those with comorbid mental illness often refuse psychiatric referral. As a result, it is imperative that dermatologists be mindful of psychiatric comorbidity in their patients and comfortable with the fundamentals of psychodermatologic diagnosis and therapy. This update summarizes current concepts, relevance, and therapeutics in psychodermatology, including aspects pertinent to depression, anxiety, obsessive-compulsive, impulse-control, and delusional disorders as described in the Diagnostic and Statistical Manual of Mental Disorders 5th edition (DSM-5, published in 2013 by the American Psychiatric Association).

BACKGROUND: In Germany, neurological-neurosurgical early rehabilitation is well established in the treatment of severe neurological diseases. To develop quality standards, knowledge of the current rehabilitation course is required. PATIENTS AND METHODS: A retrospective analysis was performed on the course of rehabilitation from patients in an early neurological/neurosurgical rehabilitation program in 16 centers from 10 German states. The odds for a good or poor outcome were investigated using a multivariate logistic regression model. RESULTS: Seven hundred and fifty-four patients were included in the study. The average age of the patients was 68 ± 15 years. Of the patients studied, 26â¯% were on mechanical ventilation commencing their neurological rehabilitation. The average duration of stay was 56 ± 51 days. Weaning rate from mechanical ventilation was 65â¯% and the rate of weaning from tracheal cannula was 54â¯%. Mean improvement in the Barthel Index of 17 points, significant reduction of dysphagia (from 62 to 30â¯%) and depended walking (from 99 to 82â¯%), and the achievement of phase C (the next stage of rehabilitation) in 38â¯% can still be counted as signs of successful rehabilitation. During their course of stay, near 10â¯% of the patients died. Of these, 67â¯% received solely palliative care. In the multivariate logistic models, the absence of the factor "necessity for mechanical ventilation on admission" (odds ratio 0.61; 95 % confidence interval (CI): 0.42 0.89) increased the chance for good outcome and the presence of this factor the risk of dying with an odds ratio of 8.07 (95 % CI: 4.54-14.34). DISCUSSION: In spite of the severity of neurological deficits, significant functional progress has been made. These results could be interpret as positive proof of the efficacy of neurological/neurosurgical early rehabilitation programs.

During the last 1.5 years an update of the guideline on silicosis was made by an interdisciplinary working group. New medical and scientific knowledge and the experience in expert opinion practice were taken into account.By preparing the initial guideline in 2010 standardization of diagnostics and adaption of the "Moers convention" which was not based on medical knowledge was in the focus, whereas the current update deals with fine emendation and extension, especially of the compensation rate (adaption with the Reichenhall recommendation).The diagnosis of silicosis (including mixed dust pneumoconiosis) is based on a detailed occupational history, and predominantly on the typical radiological findings. However, at initial diagnosis the standardized LD-HRCT takes an important role because of its high sensitivity and specificity. Exceptional cases are those with characteristic findings in chest X-ray follow-up. Correspondingly, it is mentioned in the guideline: "The standardized appraisal of the Low-Dose-Volume HRCT requires application of the CT classification (ICOERD, International Classification of Occupational and Environmental Respiratory diseases). In order to diagnose silicosis in CT scan opacities with sharp borders in both central upper lung fields and their circumferencies have to be documented. By comparing with ILO standard radiographs at least profusion category 1 in the right and left upper lung fields has to be reached (total profusion category 2)."The pathologic minimal requirement for the diagnosis of silicosis which has undergone controversial discussion has now also been defined. Corresponding to Hnizdo et al. 2000 it is now mentioned: "Finding of less than 5 silicotic granuloma per lung lobe by palpation is regarded as insignificant." This is a convention and not a threshold based on detailed medical scientific and statistical studies; it is based on extended experience in the South African gold mines.This guideline also deals with silicotic hilar (and sometimes mediastinial) lymph nodes; according to the guideline working group they do not closely correlate with the degree of pulmonary involvement. Extended conglomerating and enduring lymph-node processes may lead to dislocation of the hili with impairment of large bronchi and vessels.
