Spirometric patterns in young and middle-aged adults: a 20-year European study.

BACKGROUND: Understanding the natural history of abnormal spirometric patterns at different stages of life is critical to identify and optimise preventive strategies. We aimed to describe characteristics and risk factors of restrictive and obstructive spirometric patterns occurring before 40 years (young onset) and between 40 and 61 years (mid-adult onset). METHODS: We used data from the population-based cohort of the European Community Respiratory Health Survey (ECRHS). Prebronchodilator forced expiratory volume in one second (FEV1) and forced vital capacity (FVC) were assessed longitudinally at baseline (ECRHS1, 1993-1994) and again 20 years later (ECRHS3, 2010-2013). Spirometry patterns were defined as: restrictive if FEV1/FVC≥LLN and FVC<10th percentile, obstructive if FEV1/FVC

Prospective associations of technostress at work, burnout symptoms, hair cortisol, and chronic low-grade inflammation.

BACKGROUND: Working conditions in the age of digitalization harbor risks for chronic stress and burnout. However, real-world investigations into biological effects of technostress, that is stress in the context of digital technology use, are sparse. This study prospectively assessed associations between technostress, general work stress, burnout symptoms, hair cortisol, and chronic low-grade inflammation. METHODS: Hospital employees (N = 238, 182 females, Mage = 28.5 years) participated in a prospective cohort study with two follow-ups six months apart (T2, T3). Participants answered standardized questionnaires on general job strain (job demand-control ratio), technostressors (work interruptions, multitasking, information overload), burnout symptoms (exhaustion, mental distance), and relevant confounders. Moreover, they provided capillary blood samples for C-reactive protein (CRP) and hair strands for hair cortisol concentration (HCC) analysis. Structural equation modelling was performed. RESULTS: The factorial structure of survey measures was confirmed. Burnout symptoms (MT2 = 2.17, MT3 = 2.33) and HCC (MT2 = 4.79, MT3 = 9.56; pg/mg) increased over time, CRP did not (MT2 = 1.15, MT3 = 1.21; mg/L). Adjusted path models showed that technostress was negatively associated with HCC (ß = -0.16, p =.003), but not with burnout and CRP. General work stress in contrast, was not significantly associated with burnout, HCC or CRP. Furthermore, there were reciprocal effects of CRP on HCC (ß = 0.28, p =.001) and of HCC on CRP (ß = -0.10, p ≤.001). Associations were robust in additional analyses including further confounders. CONCLUSION: This is the first study on prospective effects of technostress on employees' endocrine and inflammatory systems. Results suggest differential effects of technostress on the hypothalamic-pituitary-adrenocortical axis activity. Given its key role for long-term health, the findings have important implications for occupational health and safety in digitalized work environments.

A call from 40 public health scientists for an end to the continuing humanitarian and environmental catastrophe in Gaza.

An under-recognised aspect of the current humanitarian catastrophe in Gaza is the impact of the war on the environment and the associated risks for human health. This commentary contextualises these impacts against the background of human suffering produced by the overwhelming violence associated with the use of military force against the general population of Gaza. In calling for an immediate cessation to the violence, the authors draw attention to the urgent need to rebuild the health care system and restore the physical and human infrastructure that makes a liveable environment possible and promotes human health and well-being, especially for the most vulnerable in the population. Environmental remediation should therefore form one of the most important parts of international efforts to assist reconstruction, through which we hope Palestinians and Israelis will achieve lasting peace, health, and sustainable development, all as part of accepted international human rights obligations.

The impact of years of training and possible technical, procedural, and individual risk factors for the development of atopic symptoms among bakery and confectionery trainees.

PURPOSE: Occupational asthma is commonly observed in bakers and confectioners. Endogenous and exogenous risk factors contribute to bakers' asthma. A heightened awareness of this and early diagnosis can be helpful in terms of prevention. The aim of the study was to identify a temporal relationship between the years of training, as well as possible technical, procedural, and individual risk factors for the development of flour-exposure related atopic symptoms such as rhinitis, cough, and rash in young professionals. METHODS: 127 bakers and confectioner trainees were observed over a one-year period. Two questionnaires served as test instruments. It was investigated whether the rates of atopic symptoms change over the course of a school year and which conditions in the workplace could be responsible for this. Descriptive statistics were used to answer the research questions concerning flour exposure and symptom rates. The Pearson-Chi-Square test was used for testing statistical differences between different groups (e.g. year of training, working conditions). RESULTS: An increase in rates of self-reported rhinitis, coughing, and rashes throughout the duration of traineeship was shown (e.g. rhinitis of bakers at work: 0% in the first year of training, 20% in the second and 33% in the third year of training). The installation of vapour extraction systems and low-dust transfer of baking agents led to fewer symptoms in the workplace (30% of participants with rhinitis symptoms worked with no installed vapour extraction systems). A medical history of atopy was positively correlated with the occurrence of symptoms. CONCLUSION: To prevent the development of asthma in bakers, methods to improve occupational health and safety should be developed. Creating low dust working conditions e.g., due to the use of vapour extraction systems should be considered.

Effects of heat and personal protective equipment on thermal strain in healthcare workers: part B-application of wearable sensors to observe heat strain among healthcare workers under controlled conditions.

PURPOSE: As climate change accelerates, healthcare workers (HCW) are expected to be more frequently exposed to heat at work. Heat stress can be exacerbated by physical activity and unfavorable working requirements, such as wearing personal protective equipment (PPE). Thus, understanding its potential negative effects on HCW´s health and working performance is becoming crucial. Using wearable sensors, this study investigated the physiological effects of heat stress due to HCW-related activities. METHODS: Eighteen participants performed four experimental sessions in a controlled climatic environment following a standardized protocol. The conditions were (a) 22 °C, (b) 22 °C and PPE, (c) 27 °C and (d) 27 °C and PPE. An ear sensor (body temperature, heart rate) and a skin sensor (skin temperature) were used to record the participants´ physiological parameters. RESULTS: Heat and PPE had a significant effect on the measured physiological parameters. When wearing PPE, the median participants' body temperature was 0.1 °C higher compared to not wearing PPE. At 27 °C, the median body temperature was 0.5 °C higher than at 22 °C. For median skin temperature, wearing PPE resulted in a 0.4 °C increase and higher temperatures in a 1.0 °C increase. An increase in median heart rate was also observed for PPE (+ 2/min) and heat (+ 3/min). CONCLUSION: Long-term health and productivity risks can be further aggravated by the predicted temperature rise due to climate change. Further physiological studies with a well-designed intervention are needed to strengthen the evidence for developing comprehensive policies to protect workers in the healthcare sector.

Implications of Switching from Conventional to Electronic Cigarettes on Quality of Life and Smoking Behaviour: Results from the EQualLife Trial.

INTRODUCTION: Electronic cigarettes and "vaping" have become popular since their appearance in Europe and the USA in approximately 2006. They are often perceived as having fewer health risks than conventional cigarettes, which makes them of interest as a support tool in smoking cessation. However, its efficacy regarding cessation or reduction of smoking under real-life conditions remains controversial. Our objective was to clarify this question in an observational study of smoking habits after initiating vaping without targeted intervention, as compared to a validated cessation programme. METHODS: From October 2015 to April 2018, 80 subjects (60 in the e-cigarette group and 20 in the supervised smoking cessation group) were included in two trial visits, one at the start of the trial and the second after 3 months, plus 4 questionnaire surveys: at the start of the trial and after a 1, 2, and 3 month period. The questionnaire included a nicotine use inventory, a modified Fagerström test for nicotine dependence, and the WHO-QOL-BREF survey. RESULTS: E-cigarettes were effective, leading to a significant (p < 0.03) reduction (p < 0.03) in tobacco consumption and nicotine dependence, with an abstinence rate of 43% after 3 months. Compared to participants in the smoking cessation programme, their use was not associated with an improvement in quality of life during the quitting attempt, and there were no significant differences in clinical symptoms between groups. The reduction in nicotine dependence was more pronounced (p < 0.012) for the smoking cessation programme, with higher abstinence rates (p = 0.011 after 12 weeks) and lower (p < 0.003) remaining tobacco consumption compared to electronic cigarettes. DISCUSSION/CONCLUSIONS: The use of electronic cigarettes reduced nicotine dependence and tobacco consumption, but a supervised smoking cessation programme was superior in terms of achieved cessation in both regards. Electronic cigarettes did not improve the quality of life. Since e-cigarettes could be associated with long-term health risks, their usefulness in smoking cessation remains questionable, and a professionally guided and validated smoking cessation programme still appears to be superior and preferable, in terms of achieved cessation. Although this trial is limited regarding the number of participants and follow-up time, it highlights the need for additional, large clinical trials evaluating the efficacy of e-cigarettes for smoking cessation in comparison to a professionally guided smoking cessation programme.

[Economic Relevance of Preventable Prohibitions of Employment in Bavarian Schools]. / Ökonomische Relevanz vermeidbarer Beschäftigungsverbote an Schulen in Bayern.

INTRODUCTION: According to the Maternity Protection Act, an occupational risk of infection (e. g. in childcare) - combined with individual immunity gaps - can result in an irresponsible risk for pregnant women in the workplace. If this risk cannot be eliminated by any other means, the employer must impose a prohibition of employment (PE) for the pregnant woman concerned. We classified PE as preventable if the underlying immunity gaps could have been closed by immunisation prior to pregnancy. METHODS: From 01.09.2016 to 25.03.2020, 1922 pregnant employees of Bavarian state schools obtained medical counselling on their occupational risk of infection as part of a research project. If the individual combination of occupational-risk profile and immunity status resulted in an irresponsible risk for the pregnancy, a PE was recommended by the attending physician. We determined the proportion of PE that would have theoretically been preventable by full immunisation prior to pregnancy and approximated the resulting - theoretically preventable - loss of working hours and personnel costs. RESULTS: In 425 cases (22%), a PE was deemed necessary by the attending physician, whereby 193 (45%) were retrospectively classified as theoretically preventable. Of these cases, 53 PE (27%) were temporary (valid until the 20th week of pregnancy) and 140 were long-term (valid for the complete duration of the pregnancy). Based on these results, we approximated a loss of 2,746 working weeks for our collective, which entails theoretically preventable personnel costs totalling 5,763,305 € for the observation period of our study (3.6 years). We then extrapolated estimates for all employees of Bavarian state schools and found a loss of 4,260 working weeks and theoretically preventable personnel costs amounting to almost 8,941,000 € per year during our observation period. CONCLUSION: Theoretically preventable PE caused by immunity gaps can entail a considerable loss of working hours and high personnel costs. Therefore, we should step up measures aimed at improving vaccination rates in women and increasing their willingness to be vaccinated. In view of the changes in legal and regulatory conditions in Germany since 2020, new investigations should be made as soon as there is sufficient data after the general employment prohibitions due to the SARS-CoV-2-pandemic have been lifted.

[Effects of pulmonary rehabilitation on dysfunctional respiratory patterns in patients with uncontrolled asthma]. / Effekte der pneumologischen Rehabilitation auf dysfunktionale Atemmuster bei Patienten mit unkontrolliertem Asthma.

PURPOSE: Dysfunctional breathing patterns (DAM) are deviations from physiologic breathing patterns. DAM seem to be associated with lower asthma control. To date, it is unclear what effect inpatient rehabilitation can have on this problem. The aim of this work is to investigate the effect of pulmonary rehabilitation (PR) on DAM. METHODS: The data are based on a randomized controlled trial with a waiting control group. The intervention group (IG) received PR 4 weeks after application approval and the control group (KG) after 5 months. Dysfunctional breathing was assessed by Nijmegen-Questionnaire (NQ). Values ≥ 23 points indicate an existing DAM. Values at the end of rehabilitation (T2) and after three months (T3) were compared (analysis of covariance). Supplemental moderator analysis was performed to examine whether the effect of PR was related to baseline NQ scores. RESULTS: Significant differences in NQ score are found between IG (n=202) and KG (n=210) at T2 (AMD=10.5; 95%CI [9; 12]; d=1.4; p<0.001) and at T3 (AMD=5.8; 95%CI [4.3; 7.3]; d=0.8; p<0.001). There is an interaction effect between the difference in NQ score between the groups at T2 and baseline at T0 (b=5.6; 95%CI [2.2; 11.9]; p<0.001). At T3, this interaction effect was no longer detectable (b=4.5; 95%CI [-3.1; 14.1]; p=807). CONCLUSION: Inpatient, multimodality, and interdisciplinary PR is associated with significant and clinically relevant improvement in DAM both at discharge and 3 months later. In the short term, patients with existing DAM benefit more from PR than patients without DAM.

[Prevention of progression of allergic bronchial asthma as an occupational disease]. / Prävention eines Progresses des allergischen Asthma bronchiale als Berufskrankheit.

Since January 1st, 2021, termination of a harmful activity as a requirement for its recognition as an occupational disease (OD) has been abolished in Germany. This also includes the OD No. 4301 in accordance with Appendix 1 of the Occupational Diseases Ordinance (ODO) (obstructive respiratory diseases caused by allergenic substances). There has already been a significant increase in the number of diseases recognized under this OD. In this article, we present two patients with allergic (in the second case report mixed-form) bronchial asthma, in whom a medically easily preventable disease progression occurred as a result of continued occupational exposure to allergens as a farmer. According to § 3 (1) ODO, if there is a "risk that an occupational disease will develop, recur or worsen", the statutory accident insurance institutions are obliged to "counteract this danger with all suitable means". These individual preventive measures are compulsory by law and medically sensible, even under circumstances where only the risk of the genesis of an OD is given. Nonetheless, they are likely to be indicated and offered more frequently in the future due to an increased recognition of ODs. Unfavorable clinical courses such as those described in the two case reports presented here should therefore occur less frequently in the future.

[Everything under control?] / Alles unter Kontrolle?

A 43-year-old quarry worker, after being exposed to fine quartz dust for 16 years in a German quarry, is on the waiting list for a lung transplant. The inhalation of the fine dust irreversibly damaged his lungs and facilitated the occurrence of fulminant mycobacterial and fungal infections, which have already led to a unilateral pneumonectomy and increasing respiratory failure. Despite regular monitoring by the occupational health and safety board, this dramatic development of silicosis could not be prevented.

[Development of two questionnaires for the assessment of knowledge and self-management in patients with chronic-obstructive pulmonary disease (COPD)]. / Entwicklung zweier Fragebögen zum Krankheitswissen und Umgang mit der Erkrankung für Patienten mit chronisch-obstruktiver Lungenerkrankung (COPD).

INTRODUCTION: As with other chronic diseases, the course of chronic obstructive pulmonary disease (COPD) can be expected to be positively influenced if patients are well informed about their disease and undertake appropriate self-management. Assessments of the level of knowledge and management that are comparable should benefit from structured, systematically developed questionnaires. These, however, have not been published in Germany. METHODS: A total of 310 patients with COPD were recruited from three pneumological practices and one hospital to develop the questionnaires. Based on statistical criteria and content assessments by medical specialists, two questionnaires on knowledge (17 questions) and self-management (25 questions) were developed by selecting and modifying questions from published studies and training programs. In addition, two short versions with 5 and 3 questions were created to enable a quick assessment of the patients' knowledge and self-management. All questionnaires also included a visual analogue scale for self-assessment of knowledge and self-management. The statistical procedures for systematically guided selection comprised correlation and regression analyses. RESULTS: The questionnaires revealed considerable knowledge deficits in many patients and remarkably unsystematic, incoherent knowledge. The extent of this knowledge was negatively correlated with higher age and positively correlated with participation in training programs; this also applied to self-management. Correlations between the answers to the knowledge questions were higher in patients who had participated in training programs. The visual analogue scales for self-assessment of knowledge and management always correlated with the total number of correct answers. DISCUSSION: The questionnaires on knowledge and self-management in patients with COPD could be used in outpatient settings, including by non-medical staff, in order to quickly identify and correct deficits or as a reason to recommend training programs. The short versions and the analogue scales for self-assessment can give at least first hints. Potentially, training programs should focus more on promoting the coherence of knowledge through better understanding, as this presumably favors long-term knowledge. Older patients and those with a low level of education appear to be particularly in need of specially adapted training programs.

Long-term effect of asthma on the development of obesity among adults: an international cohort study, ECRHS.

INTRODUCTION: Obesity is a known risk factor for asthma. Although some evidence showed asthma causing obesity in children, the link between asthma and obesity has not been investigated in adults. METHODS: We used data from the European Community Respiratory Health Survey (ECRHS), a cohort study in 11 European countries and Australia in 3 waves between 1990 and 2014, at intervals of approximately 10 years. We considered two study periods: from ECRHS I (t) to ECRHS II (t+1), and from ECRHS II (t) to ECRHS III (t+1). We excluded obese (body mass index≥30 kg/m2) individuals at visit t. The relative risk (RR) of obesity at t+1 associated with asthma at t was estimated by multivariable modified Poisson regression (lag) with repeated measurements. Additionally, we examined the association of atopy and asthma medication on the development of obesity. RESULTS: We included 7576 participants in the period ECRHS I-II (51.5% female, mean (SD) age of 34 (7) years) and 4976 in ECRHS II-III (51.3% female, 42 (8) years). 9% of participants became obese in ECRHS I-II and 15% in ECRHS II-III. The risk of developing obesity was higher among asthmatics than non-asthmatics (RR 1.22, 95% CI 1.07 to 1.38), and particularly higher among non-atopic than atopic (1.47; 1.17 to 1.86 vs 1.04; 0.86 to 1.27), those with longer disease duration (1.32; 1.10 to 1.59 in >20 years vs 1.12; 0.87 to 1.43 in ≤20 years) and those on oral corticosteroids (1.99; 1.26 to 3.15 vs 1.15; 1.03 to 1.28). Physical activity was not a mediator of this association. CONCLUSION: This is the first study showing that adult asthmatics have a higher risk of developing obesity than non-asthmatics, particularly those non-atopic, of longer disease duration or on oral corticosteroids.

Cumulative occupational exposure to gases and fumes is associated with impairment in lung function and disease-related quality of life in a German COPD patient cohort.

OBJECTIVES: The impact of occupational exposures on lung function impairments and quality of life (QoL) in patients with chronic obstructive pulmonary disease (COPD) was analysed and compared with that of smoking. METHODS: Data from 1283 men and 759 women (Global Initiative for Chronic Obstructive Lung Disease (GOLD) grades 1-4 or former grade 0, without alpha-1-antitrypsin deficiency) of the COPD and Systemic Consequences Comorbidities Network cohort were analysed. Cumulative exposure to gases/fumes, biological dust, mineral dust or the combination vapours/gases/dusts/fumes was assessed using the ALOHA job exposure matrix. The effect of both occupational and smoking exposure on lung function and disease-specific QoL (St George's Respiratory Questionnaire) was analysed using linear regression analysis adjusting for age, body mass index, diabetes, hypertension and coronary artery disease, stratified by sex. RESULTS: In men, exposure to gases/fumes showed the strongest effects among occupational exposures, being significantly associated with all lung function parameters and QoL; the effects were partially stronger than of smoking. Smoking had a larger effect than occupational exposure on lung diffusing capacity (transfer factor for carbon monoxide) but not on air trapping (residual volume/total lung capacity). In women, occupational exposures were not significantly associated with QoL or lung function, while the relationships between lung function parameters and smoking were comparable to men. CONCLUSIONS: In patients with COPD, cumulative occupational exposure, particularly to gases/fumes, showed effects on airway obstruction, air trapping, gas uptake capacity and disease-related QoL, some of which were larger than those of smoking. These findings suggest that lung air trapping and QoL should be considered as outcomes of occupational exposure to gases and fumes in patients with COPD. TRIAL REGISTRATION NUMBER: NCT01245933.

Evaluation of long-term data on surface contamination by antineoplastic drugs in pharmacies.

PURPOSE: The handling of antineoplastic drugs represents an occupational health risk for employees in pharmacies. To minimize exposure and to evaluate cleaning efficacy, wipe sampling was used to analyze antineoplastic drugs on surfaces. In 2009, guidance values were suggested to facilitate the interpretation of results, leading to a decrease in surface contamination. The goal of this follow-up was to evaluate the time trend of surface contamination, to identify critical antineoplastic drugs and sampling locations and to reassess guidance values. METHODS: Platinum, 5-fluorouracil, cyclophosphamide, ifosfamide, gemcitabine, methotrexate, docetaxel and paclitaxel were analyzed in more than 17,000 wipe samples from 2000 to 2021. Statistical analysis was performed to describe and interpret the data. RESULTS: Surface contaminations were generally relatively low. The median concentration for most antineoplastic drugs was below the limit of detection except for platinum (0.3 pg/cm2). Only platinum and 5-fluorouracil showed decreasing levels over time. Most exceedances of guidance values were observed for platinum (26.9%), cyclophosphamide (18.5%) and gemcitabine (16.6%). The most affected wipe sampling locations were isolators (24.4%), storage areas (17.6%) and laminar flow hoods (16.6%). However, areas with no direct contact to antineoplastic drugs were also frequently contaminated (8.9%). CONCLUSION: Overall, the surface contaminations with antineoplastic drugs continue to decrease or were generally at a low level. Therefore, we adjusted guidance values according to the available data. The identification of critical sampling locations may help pharmacies to further improve cleaning procedure and reduce the risk of occupational exposure to antineoplastic drugs.

Associations of technostressors at work with burnout symptoms and chronic low-grade inflammation: a cross-sectional analysis in hospital employees.

OBJECTIVE: Despite the increasing scholarly interest in the phenomenon technostress, associated biological effects on employee health are under-researched. Chronic low-grade inflammation is suggested as a central pathway linking stress experience to disease development. The aim of this study was to assess associations of technology-related work stressors (technostressors) with low-grade inflammation and burnout symptoms. METHODS: N = 173 (74.6% women, Mage = 31.0 years) university hospital employees participated in a cross-sectional study. Self-report questionnaires were used for the assessment of general psychosocial working conditions (work overload, job control, social climate), a range of different technostressors, burnout symptoms, and relevant confounders. Participants provided capillary blood samples, and high-sensitivity C-reactive protein (hs-CRP) as an inflammatory biomarker was analyzed from dried blood spots. RESULTS: Based on a factor analysis, we identified four underlying dimensions of technostressors: techno- and information overload, techno-complexity, interruptions and multitasking as well as usability and technical support. In multivariate linear regressions, techno-/information overload and techno-complexity were associated with core (exhaustion, mental distance) and secondary (psychosomatic complaints) symptoms of burnout. Techno-/information overload was a significant predictor of burnout core symptoms, even when general work overload was controlled for. The technostressors were not associated with hs-CRP. CONCLUSION: This is the first study on technology-related stress at work and chronic low-grade inflammation. The results suggest that (information) overload caused by digital technology use is a distinct work stressor with genuine consequences for psychological health. To what extent these effects also manifest on a physiological level needs to be subjected to future studies, ideally with prospective designs.

Farm living and allergic rhinitis from childhood to young adulthood: Prospective results of the GABRIEL study.

BACKGROUND: Growing up on a farm is associated with a reduced prevalence of respiratory allergies in childhood. Whether this protective effect remains into adulthood is unknown. OBJECTIVES: We aimed to prospectively investigate the relationship between farm exposure and prevalence of allergic rhinitis and wheeze from childhood to early adulthood. METHODS: Participants from phase 2 of the Multidisciplinary Study to Identify the Genetic and Environmental Causes of Asthma in the European Community (GABRIEL) who were living in southern Germany (aged 6-11 years at baseline and 20-25 years at follow-up) were invited to complete a questionnaire on sociodemographic data, farm contact, respiratory symptoms, and potential confounders. Odds ratios (ORs) with 95% CIs were modeled by using generalized estimating equations. RESULTS: Of the 2276 phase 2 participants, 1501 (66%) answered the follow-up questionnaire, of whom 1333 could be included in the analyses. Living on a farm was associated with reduced prevalence of allergic rhinitis (OR with persistent farm living = 0.4 [95% CI = 0.2-0.6]; OR with farm living at baseline only = 0.4 [95% CI = 0.2-0.8]). The OR for development of symptoms from baseline to follow-up was almost 3 (OR = 2.7 [95% CI = 2.1-3.3]) irrespective of farm living. For symptoms of wheeze, no statistically significant association with farm living was observed. CONCLUSIONS: The protective effect of farm living on allergic rhinitis persists from childhood to early adulthood. Continuing exposure over puberty does not add to the effect. This confirms that the window of opportunity for a protective effect might be found in childhood.

[Patient Care in German Outpatient Clinics for Environmental Medicine Illustrated by the Examples of Hamburg and Munich University Hospitals]. / Versorgung von Patient*innen an umweltmedizinischen Ambulanzen in Deutschland am Beispiel der Universitätskliniken in Hamburg und München.

People can be affected by various environmental factors (e. g., odor, noise) which can lead to medical complaints or illnesses. Few adequate contact points are available for patients with suspected environmental complaints in Germany. Illustrated by the outpatient clinics for environmental medicine in Hamburg and Munich, this report shows how patients with suspected environmental medical diseases are cared for in Germany. For the exemplary presentation, the data of the environmental medicine outpatient clinics of both the university hospitals from 01.01.2019 to 31.03.2021 are presented and compared. Overall, more female than male patients were treated at both facilities. Suspected exposure to "heavy metals" was most frequently mentioned by patients as the assumed reason for their complaints. Nonetheless, the suspected exposure or "intoxication" could be ruled out in the majority of cases by appropriate examination methods in accordance to current medical guidelines. The data provided by the environmental medicine outpatient clinics show that there is a continuous demand for environmental medical care. A close cooperation between the private practice sector and the outpatient clinics for environmental medicine providing medical care to patients should therefore be sought.

Work-related stress and atopic dermatitis: Results from the study on occupational allergy risks.

Chronic stress at work is ubiquitous in modern societies. However, its influence on atopic dermatitis (AD) has hardly been investigated. This study aimed to elucidate the association between work-related stress and AD via a longitudinal study. The analysis comprised data from three phases (2002-2003, 2007-2009, 2017-2018) of the prospective Study on Occupational Allergy Risks (SOLAR), including 1,240 young adults aged 16 to 18 years at baseline (61% female) who were originally recruited for the International Study of Asthma and Allergies in Childhood Phase II in 1995-1996. AD was assessed at all three phases based on self-reports of a physician's diagnosis and symptoms. Work-related stress was measured at all three periods using the work discontent and work overload scales from the Trier Inventory for the Assessment of Chronic Stress with adaptions to school and university. Generalized estimating equations were used to analyze the association between stress and AD, treating work discontent and work overload first as continuous and then as categorical exposure variables. We observed 50 AD cases (4%) at SOLAR I, 48 (4%) at SOLAR II, and 42 (3%) at SOLAR III. A one-point increase in the work discontent score was associated with an odds ratio (OR) for AD of 1.05 (95% confidence interval [CI], 1.00-1.10). The respective increase in the work overload score led to an OR of 1.03 (95% CI, 0.99-1.06). In the categorical analysis, there was no clear indication of elevated odds of AD in the highest vs. lowest exposure group (4th vs. 1st quartile: OR, 1.53; 95% CI, 0.92-2.53 for work discontent; OR, 1.38, 95% CI, 0.83-2.27 for work overload). Altogether, we observed limited to no evidence for an association between work-related stress and AD. Our study's ability to detect stronger evidence may have been compromised by shortcomings such as nondifferential misclassification of the outcome or insufficient statistical precision due to small numbers of AD cases. Another explanation could be that AD predominantly becomes evident in childhood, not in adulthood.

[Patient-Reported Outcomes (PROs) 3 and 6 Months After Pulmonary Rehabilitation Following COVID-19]. / Patient-Reported Outcomes (PROs) 3 und 6 Monate nach pneumologischer Post-COVID-Rehabilitation.

PURPOSE: If COVID-19 disease sequelae also (co-)affect the respiratory organs, national and international guidelines recommend pulmonary rehabilitation (PR). So far, however, no studies are available from Germany on the course after PR, nor on possible course differences between the two Long COVID subgroups "Ongoing symptomatic COVID-19" and "Post-COVID-19 syndrome" (PCS). METHODS: In a prospective observational study, patient-reported outcomes (PROs) regarding exertional dyspnea, quality of life, pain, fatigue, depression, and anxiety were assessed at the beginning of PR (T1), end of PR (T2), and after 3 (T3) and 6 months (T4). Statistical analyses were performed using latent difference models. RESULTS: There were 224 rehabilitation patients (MAge=54.4; SDAge=10.4; 42.0% female) included in the study. During PR, all PROs improved significantly. After PR, improvements either persisted with large pre-post effect sizes (exertional dyspnea, quality of life), decreased slightly to small pre-post effect sizes (depression, fatigue), or decreased to baseline levels (anxiety, pain). PCS patients had greater burdens in depression, fatigue, and pain at baseline, but did not differ in trajectories. Indicators of the severity of the preceding acute phase (oxygen therapy, ICU treatment, ventilation) were associated with higher burdens at T0 in depression, fatigue, and pain, but not with the courses during and after PR. In contrast, female patients showed higher burdens in both depression and fatigue at T1 and higher pre-post effects than male patients. CONCLUSION: The fact that improvements in PROs occurred in both subgroups only during PR, but not during the follow-up period suggests that the changes are not due to the natural healing process but at least partly due to PR. Moreover, the results suggest that both patient groups may benefit from PR. Persisting improvements in exertional dyspnea and quality of life and, to a reduced extent, in depression and fatigue until 6 months after PR, but not in pain and anxiety warrant study of additional multimodal interventions that may be needed to maintain these effects.

[Occupational obstructive airway diseases: How can early diagnosis be made to avoid chronic courses?] / Obstruktive Atemwegserkrankungen im Beruf: Wie gelingt eine frühe Diagnostik zur Vermeidung chronischer Verläufe?

Since abolishing the obligation to terminate the harmful professional activity from January 1st, 2021 onwards for some occupational diseases including obstructive respiratory diseases in Germany, the recognition of occupational diseases coded under 4301, 4302 and 1315 according the Occupational Diseases Ordinance has increased significantly. By the time these diseasese are recognized, they are usually already at an advanced stage. Therefore, early detection will play a greater role in the future, as the statutory accident insurance can offer individual preventive measures in order to minimize the consequences of illness and thus also the socio-economic burden.
