Predictors of benefit from an atopic dermatitis education programme.

BACKGROUND: Multidisciplinary, age-related, structured, group educational programmes for children with atopic dermatitis (AD) and their parents have shown positive long-term outcomes with respect to quality of life and coping behaviour of the participants. We aimed to identify predictors of favourable long-term outcome of an education measure for parents of children with AD aged 3 months to 7 years in the framework of The German Atopic Dermatitis Intervention Study (GADIS). METHODS: In an exploratory approach, the data of 274 child-parent pairs were analysed with respect to the influence of various somatic and psychological variables as possible predictors of treatment success. Changes in parents' QoL, SCORAD (Scoring Atopic Dermatitis), topical corticosteroid use and parents' knowledge about AD between baseline and 12-months' follow-up were chosen as measures of long-term treatment success (outcome). RESULTS: Psychological rather than somatic parameters were identified as predictors of treatment success. Parents who had negative treatment experiences in the past and possessed only poor coping abilities with regard to scratch control benefitted the most from the training programme. The outcome of the education measure was independent of parents' schooling, vocational level and income. CONCLUSIONS: Parents of children with AD who lack adequate coping abilities should be particularly encouraged to take part in such an education programme.

[Climate change and child health: A nationwide survey among paediatricians in Germany]. / Klimawandel und Kindergesundheit: eine bundesweite Befragung von Pädiater*innen in Deutschland.

BACKGROUND: Children are a vulnerable group affected by climate change. Paediatricians are important actors in protecting children from climate change-related health risks and in identifying and treating relevant health effects. The main objectives of this study were to determine how paediatricians assess the relevance of climate change-related health impacts, through which channels paediatricians can be reached most effectively, how often climate change-specific prevention measures are implemented and how they are assessed. METHODS: Between February and July 2020, an online survey was conducted among paediatricians. The cross-sectional survey was designed to gather knowledge and attitudes about the relevance of climate change, sources of information and prevention measures. All participants who answered only one question or none at all were excluded. Differences between groups were determined using one-factorial analysis of variance. Correlations were determined using Pearson's bivariate correlation analysis and tested for two-sided significance. RESULTS: A total of 408 questionnaires were analysed. Over 95% of the respondents were paediatricians, with just under half of them working in children's hospitals and a good third in paediatric practices. According to paediatricians, climate change has a relevant impact on children's health. The most significant effects on children's health were considered to be longer and stronger pollen seasons, neophytes and neozoa, Lyme disease and TBE (tick-borne encephalitis, summer meningoencephalitis), UV radiation and air pollutants. Certified training options in professional journals and participation in lectures or workshops at relevant congresses were identified as the two preferred types of training. Especially professional journals as the most frequently used source of information could function as a suitable tool to reach as many paediatricians as possible. 76% of the paediatricians have not yet carried out any corresponding prevention activities, although information activities for parents or children were seen as being effective by 80%. Whereas the possibilities of integrating climate change-oriented prevention activities into everyday practice, were perceived less positively. The most frequent reason given was lack of time. DISCUSSION: To satisfy this future need for knowledge, but also for offerings from paediatricians for patients and their parents, concrete further continuous education and consultancy services must be prepared. In the future, further training offers, including the consultancy services, should be integrated into profession-specific training modules, presented at congresses, and then implemented into paediatricians' daily routine. CONCLUSION: The results of the study illustrate that the topic "climate change and health" has a high relevance for paediatricians and that information measures for parents are considered to be effective. Although paediatricians are concerned with the topic, there is an implementation deficit. Support is needed in the form of intensifying awareness-raising projects and educational modules for paediatricians to move from knowledge to action.

S3 guideline Allergy Prevention.

BACKGROUND: The persistently high prevalence of allergic diseases in Western industrial nations and the limited possibilities of causal therapy make evidence-based recommendations for primary prevention necessary. METHODS: The recommendations of the S3 guideline Allergy Prevention, published in its last version in 2014, were revised and consulted on the basis of a current systematic literature search. The evidence search was conducted for the period 06/2013 - 11/2020 in the electronic databases Cochrane and MEDLINE, as well as in the reference lists of current reviews and through references from experts. The literature found was screened in two filtering processes, first by title and abstract, and the remaining papers were screened in the full text for relevance. The studies included after this were sorted by level of evidence, and the study quality was indicated in terms of potential bias (low/high). The revised recommendations were formally agreed and consented upon with the participation of representatives of the relevant professional societies and (self-help) organizations (nominal group process). Of 5,681 hits, 286 studies were included and assessed. RESULTS: Recommendations on maternal nutrition during pregnancy and breastfeeding as well as on infant nutrition in the first months of life again play an important role in the updated guideline: Many of the previous recommendations were confirmed by the current data. It was specified that breastfeeding should be exclusive for the first 4 - 6 months after birth, if possible, and that breastfeeding should continue with the introduction of complementary foods. A new recommendation is that supplementary feeding of cow's milk-based formula should be avoided in the first days of life if the mother wishes to breastfeed. Furthermore, it was determined that the evidence for a clear recommendation for hydrolyzed infant formula in non-breastfed infants at risk is currently no longer sufficient. It is therefore currently recommended to check whether an infant formula with proven efficacy in allergy prevention studies is available until the introduction of complementary feeding. Finally, based on the EAACI guideline, recommendations were made for the prevention of chicken egg allergy by introducing and regularly giving thoroughly heated (e.g., baked or hard-boiled) but not "raw" chicken egg (also no scrambled egg) with the complementary food. The recommendation to introduce peanut in complementary feeding was formulated cautiously for the German-speaking countries: In families who usually consume peanut, the regular administration of peanut-containing foods in age-appropriate form (e.g., peanut butter) with the complementary diet can be considered for the primary prevention of peanut allergy in infants with atopic dermatitis (AD). Before introduction, a clinically relevant peanut allergy must be ruled out, especially in infants with moderate to severe AD. There is still insufficient evidence for an allergy-preventive efficacy of prebiotics or probiotics, vitamin D, or other vitamins in the form of supplements so that recommendations against their supplementation were adopted for the first time in the current guideline. Biodiversity plays an important role in the development of immunological tolerance to environmental and food allergens: there is clear evidence that growing up on a farm is associated with a lower risk of developing asthma and allergic diseases. This is associated with early non-specific immune stimulation due to, among other things, the greater microbial biodiversity of house dust in this habitat. This aspect is also reflected in the recommendations on animal husbandry, on which a differentiated statement was made: In families without a recognizable increased allergy risk, pet keeping with cats or dogs should not generally be restricted. Families with an increased allergy risk or with children with already existing AD should not acquire a new cat - in contrast, however, dog ownership should not be discouraged. Interventions to reduce exposure to dust mite allergens in the home, such as the use of mite allergen-proof mattress covers ("encasings"), should be restricted to patients with already proven specific sensitization against house dust mite allergen. Children born by caesarean section have a slightly increased risk of asthma - this should be taken into account when advising on mode of delivery outside of emergency situations. Recent work also supports the recommendations on air pollutants: Active and passive exposure to tobacco smoke increase the risk of allergies, especially asthma, and should therefore be avoided. Exposure to nitrogen oxides, ozone, and small particles (PM 2.5) is associated with an increased risk, especially for asthma. Therefore, exposure to emissions of nitrogen oxides, ozone, and small particles (PM 2.5) should be kept low. The authors of this guideline are unanimously in favor of enacting appropriate regulations to minimize these air pollutants. There is no evidence that vaccinations increase the risk of allergies, but conversely there is evidence that vaccinations can reduce the risk of allergies. All children, including children at risk, should be vaccinated according to the current recommendations of the national public health institutes, also for reasons of allergy prevention. CONCLUSION: The consensus of recommendations in this guideline is based on an extensive evidence base. The update of the guideline enables evidence-based and up-to-date recommendations for the prevention of allergic diseases including asthma and atopic dermatitis.

Overweight and obesity in childhood--a special challenge for public health.

The prevalence and incidence of overweight or even obese children and adolescents is significantly on the increase worldwide. According to the German Children and Adolescent Health Survey (KIGGS) conducted in 2006, 15% of all children and adolescents in Germany aged 3 through 17 years are overweight, and 6.3% of these children and adolescents are obese. On account of the long-term consequences, such as the metabolic syndrome, it can be expected that this "crisis in public health" will lead to a significantly higher expenditure of economic resources in the health care sector. Therefore it is important that public health prevention strategies analyse the key causes of overweight and obesity, and that they not only incorporate individual behaviours regarding nutrition and physical activity, but also take environmental factors, such as the residential area and traffic situation, as well as political circumstances regarding the nutrition and social aspects, into account. Even though the definition of body-mass index (BMI) has been widely accepted, the epidemiological data and the drawn percentiles are in need of a solid interpretation. There are several causes for the rising prevalence in overweight and obesity which are currently being focused on and discussed. On the individual level, the focus is on the genetic disposition and the changes in the behaviour regarding nutrition and physical exercise. Additional key influential factors like the increase in urbanisation and motorisation, the respective changes in the living environment of children and their families, and migration with its specific biosocial and cultural implications are discussed from the environmental and sociomedical, as well as the public health perspective. The article concludes with a discussion on the consequences of effective prevention strategies with reference to the Cochrane analysis from 2005. In order to be effective and successful, interventions for the prevention of overweight and obesity have to look at the structures and the environment of the person, as well as at the behavioural aspects of the individual. Such elements will be outlined based on the German "Platform Physical Activity and Nutrition".

Children's environment in Central Europe: threats and chances.

Many of the "classical" environmental hazards and risks (such as anthropogenic chemical and physical factors, e.g., asbestos, dioxin, electromagnetic fields and "pesticides") are in our countries not major determinants of children's health and well being; however, there may exist unseen or unrecognized causal contexts. Some hazards, such as UV light, noise, fine particles, tobacco smoke, legal and illegal drugs, and radon, are considered important by experts, but are still largely ignored by the public. In our society, despite of, or maybe because of the multitude of information and disinformation, adequate risk perception continues to be a problem. Furthermore, ever-new environmental toxicants will come to the surface and occupy medial interest, and thus, continuing attention is warranted. Of our children's environment, yet other facets are of prime importance: nutrition, housing and traffic and public media. Most important, however, is the fact that society (governments, administration, industry and consumers) are disregarding the long-term sustainability of their actions and behaviour, thus endangering the future of our children and grandchildren. This is in contrast with the existing declarations and official action plans. In future, ranking of priorities for research and actions will be necessary, taking into account costs and effectiveness since resources to be invested into these issues certainly will remain limited.

Medical diagnostics for indoor mold exposure.

In April 2016, the German Society of Hygiene, Environmental Medicine and Preventative Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin (GHUP)) together with other scientific medical societies, German and Austrian medical societies, physician unions and experts has provided an AWMF (Association of the Scientific Medical Societies) guideline 'Medical diagnostics for indoor mold exposure'. This guideline shall help physicians to advise and treat patients exposed indoors to mold. Indoor mold growth is a potential health risk, even without a quantitative and/or causal association between the occurrence of individual mold species and health effects. Apart from the allergic bronchopulmonary aspergillosis (ABPA) and the mycoses caused by mold, there is only sufficient evidence for the following associations between moisture/mold damages and different health effects: Allergic respiratory diseases, asthma (manifestation, progression, exacerbation), allergic rhinitis, exogenous allergic alveolitis and respiratory tract infections/bronchitis. In comparison to other environmental allergens, the sensitizing potential of molds is estimated to be low. Recent studies show a prevalence of sensitization of 3-10% in the total population of Europe. The evidence for associations to mucous membrane irritation and atopic eczema (manifestation, progression, exacerbation) is classified as limited or suspected. Inadequate or insufficient evidence for an association is given for COPD, acute idiopathic pulmonary hemorrhage in children, rheumatism/arthritis, sarcoidosis, and cancer. The risk of infections from indoor molds is low for healthy individuals. Only molds that are capable to form toxins can cause intoxications. The environmental and growth conditions and especially the substrate determine whether toxin formation occurs, but indoor air concentrations are always very low. In the case of indoor moisture/mold damages, everyone can be affected by odor effects and/or impairment of well-being. Predisposing factors for odor effects can be given by genetic and hormonal influences, imprinting, context and adaptation effects. Predisposing factors for impairment of well-being are environmental concerns, anxieties, conditioning and attributions as well as a variety of diseases. Risk groups that must be protected are patients with immunosuppression and with mucoviscidosis (cystic fibrosis) with regard to infections and individuals with mucoviscidosis and asthma with regard to allergies. If an association between mold exposure and health effects is suspected, the medical diagnosis includes medical history, physical examination, conventional allergy diagnosis, and if indicated, provocation tests. For the treatment of mold infections, it is referred to the AWMF guidelines for diagnosis and treatment of invasive Aspergillus infections. Regarding mycotoxins, there are currently no validated test methods that could be used in clinical diagnostics. From the perspective of preventive medicine, it is important that mold damages cannot be tolerated in indoor environments.

Abridged version of the AWMF guideline for the medical clinical diagnostics of indoor mould exposure: S2K Guideline of the German Society of Hygiene, Environmental Medicine and Preventive Medicine (GHUP) in collaboration with the German Association of Allergists (AeDA), the German Society of Dermatology (DDG), the German Society for Allergology and Clinical Immunology (DGAKI), the German Society for Occupational and Environmental Medicine (DGAUM), the German Society for Hospital Hygiene (DGKH), the German Society for Pneumology and Respiratory Medicine (DGP), the German Mycological Society (DMykG), the Society for Pediatric Allergology and Environmental Medicine (GPA), the German Federal Association of Pediatric Pneumology (BAPP), and the Austrian Society for Medical Mycology (ÖGMM).

This article is an abridged version of the AWMF mould guideline "Medical clinical diagnostics of indoor mould exposure" presented in April 2016 by the German Society of Hygiene, Environmental Medicine and Preventive Medicine (Gesellschaft für Hygiene, Umweltmedizin und Präventivmedizin, GHUP), in collaboration with the above-mentioned scientific medical societies, German and Austrian societies, medical associations and experts. Indoor mould growth is a potential health risk, even if a quantitative and/or causal relationship between the occurrence of individual mould species and health problems has yet to be established. Apart from allergic bronchopulmonary aspergillosis (ABPA) and mould-caused mycoses, only sufficient evidence for an association between moisture/mould damage and the following health effects has been established: allergic respiratory disease, asthma (manifestation, progression and exacerbation), allergic rhinitis, hypersensitivity pneumonitis (extrinsic allergic alveolitis), and increased likelihood of respiratory infections/bronchitis. In this context the sensitizing potential of moulds is obviously low compared to other environmental allergens. Recent studies show a comparatively low sensitizing prevalence of 3-10% in the general population across Europe. Limited or suspected evidence for an association exist with respect to mucous membrane irritation and atopic eczema (manifestation, progression and exacerbation). Inadequate or insufficient evidence for an association exist for chronic obstructive pulmonary disease, acute idiopathic pulmonary hemorrhage in children, rheumatism/arthritis, sarcoidosis and cancer. The risk of infection posed by moulds regularly occurring indoors is low for healthy persons; most species are in risk group 1 and a few in risk group 2 (Aspergillus fumigatus, A. flavus) of the German Biological Agents Act (Biostoffverordnung). Only moulds that are potentially able to form toxins can be triggers of toxic reactions. Whether or not toxin formation occurs in individual cases is determined by environmental and growth conditions, above all the substrate. In the case of indoor moisture/mould damage, everyone can be affected by odour effects and/or mood disorders. However, this is not a health hazard. Predisposing factors for odour effects can include genetic and hormonal influences, imprinting, context and adaptation effects. Predisposing factors for mood disorders may include environmental concerns, anxiety, condition, and attribution, as well as various diseases. Risk groups to be protected particularly with regard to an infection risk are persons on immunosuppression according to the classification of the German Commission for Hospital Hygiene and Infection Prevention (Kommission für Krankenhaushygiene und Infektionsprävention, KRINKO) at the Robert Koch- Institute (RKI) and persons with cystic fibrosis (mucoviscidosis); with regard to an allergic risk, persons with cystic fibrosis (mucoviscidosis) and patients with bronchial asthma should be protected. The rational diagnostics include the medical history, physical examination, and conventional allergy diagnostics including provocation tests if necessary; sometimes cellular test systems are indicated. In the case of mould infections the reader is referred to the AWMF guideline "Diagnosis and Therapy of Invasive Aspergillus Infections". With regard to mycotoxins, there are currently no useful and validated test procedures for clinical diagnostics. From a preventive medicine standpoint it is important that indoor mould infestation in relevant dimension cannot be tolerated for precautionary reasons. With regard to evaluating the extent of damage and selecting a remedial procedure, the reader is referred to the revised version of the mould guideline issued by the German Federal Environment Agency (Umweltbundesamt, UBA).

Predicting weight loss and maintenance in overweight/obese pediatric patients.

BACKGROUND: Pediatric lifestyle interventions have positive short-term effects on obese patients. Studies on long-term effects are still scarce in Europe. We investigated long-term weight patterns and sociodemographic predictors of a weight change in a large Central European (Germany, Austria and Switzerland) overweight pediatric cohort. METHODS: The APV (Adiposity Patients Verlaufsbeobachtung) database was retrospectively analyzed; 157 specialized childhood obesity centers contributed standardized data of 29,181 patients [body mass index (BMI) ≥ 90th percentile; 5-25 years old] presenting between 2000 and 2012. BMI standard deviation scores (BMI-SDS) were analyzed in a 2-year follow-up and grouped according to BMI-SDS changes. Multiple logistic regression analyses were conducted to assess associations between sociodemographic factors and weight patterns. RESULTS: 2-year follow-up data were available in 3,135 patients (54.6% female). Five distinct weight trajectories 'rapid weight loss' (n = 735, 23.4%), 'delayed success' (n = 697, 22.2%), 'cycling weight' (n = 43, 1.4%), 'initial weight loss' and 'weight rebound' (n = 383, 12.2%) and 'no weight loss throughout' (n = 1,277, 40.7%) best characterized long-term BMI-SDS changes. Younger and male patients were more likely to reduce weight and maintain weight loss. CONCLUSIONS: Our results suggest that an intervention before the onset of puberty seems promising for long-term weight maintenance in overweight children. Thus, new concepts are needed to improve long-term treatment success in patients with lower success rates.

Structured education program improves the coping with atopic dermatitis in children and their parents-a multicenter, randomized controlled trial.

OBJECTIVE: The objective of this study was to prove training-specific effects in children with atopic dermatitis (AD) and their parents concerning coping with the disease after their participation in a training program. In the 1-year follow-up, the changes in the training group were compared to the changes in a waiting control group while controlling the effects of the changes in severity scores. METHODS: One hundred eighty-five children aged 8-12 years and their parents participated in the study. Complete data sets at the 1-year follow-up were available for 185 parent-child pairs (102 training group; 83 waiting control group). In addition to the severity of the AD [measured with the Scoring Atopic Dermatitis (SCORAD)], data on children's itching-scratching cognitions and coping behavior and on parents handling their affected children were used in the analysis. To study whether the intervention group experienced an additional psychological benefit, which is not due to the SCORAD values, analyses of covariance with repeated measures with standardized residual change scores of the SCORAD as covariate were calculated. RESULTS: The intervention group showed greater improvement in children's coping behavior and in parents' handling their affected children. Additional effects of the training program not due to somatic improvement could be seen in the scales of itching-scratching cognitions and in three of four scales on parents dealing with their affected children. CONCLUSION: The training program, which was tested in the German Atopic Dermatitis Intervention Study, had effects on almost all explored psychological variables. Therefore, additional psychological benefit in the training group does not only depend on the greater improvement of SCORAD values in this group.

Itch intensity evaluated in the German Atopic Dermatitis Intervention Study (GADIS): correlations with quality of life, coping behaviour and SCORAD severity in 823 children.

The German Atopic Dermatitis Intervention Study (GADIS), which includes 823 children and adolescents, showed that age-related educational programmes are effective in the long-term management of atopic dermatitis. We investigated whether the itch severity obtained in the scoring of atopic dermatitis (SCORAD) correlates with quality of life and coping behaviour in children and parents. There were significant but low correlations between the severity of atopic dermatitis and the itch intensity. Itch and sleeplessness were significantly correlated. Significant correlations of itch with the coping behaviour and quality of life in parents of children with atopic dermatitis were measured. The coping and itching behaviour of children (8-12 years) and adolescents (13-18 years) had higher significant correlations with the itch compared with the parents' answers. Quality of life in children (8-12 years) and adolescents (13-18 years) showed a significant negative correlation with itch intensity. Quality of life, itch intensity and coping strategies should be considered when treating patients with atopic dermatitis.

Age related, structured educational programmes for the management of atopic dermatitis in children and adolescents: multicentre, randomised controlled trial.

OBJECTIVE: To determine the effects of age related, structured educational programmes on the management of moderate to severe atopic dermatitis in childhood and adolescence. DESIGN: Multicentre, randomised controlled trial. SETTING: Seven hospitals in Germany. PARTICIPANTS: Parents of children with atopic dermatitis aged 3 months to 7 years (n = 274) and 8-12 years (n = 102), adolescents with atopic dermatitis aged 13-18 years (n = 70), and controls (n = 244, n = 83, and n = 50, respectively). INTERVENTIONS: Group sessions of standardised intervention programmes for atopic dermatitis once weekly for six weeks or no education (control group). MAIN OUTCOME MEASURES: Severity of eczema (scoring of atopic dermatitis scale), subjective severity (standardised questionnaires), and quality of life for parents of affected children aged less than 13 years, over 12 months. RESULTS: Significant improvements in severity of eczema and subjective severity were seen in all intervention groups compared with control groups (total score for severity: age 3 months to 7 years - 17.5, 95% confidence intervals - 19.6 to - 15.3 v - 12.2, - 14.3 to - 10.1; age 8-12 years - 16.0, - 20.0 to - 12.0 v - 7.8, - 11.4; - 4.3; and age 13-18 years - 19.7, - 23.7 to - 15.7 v - 5.2, - 10.5 to 0.1). Parents of affected children aged less than 7 years experienced significantly better improvement in all five quality of life subscales, whereas parents of affected children aged 8-12 years experienced significantly better improvement in three of five quality of life subscales. CONCLUSION: Age related educational programmes for the control of atopic dermatitis in children and adolescents are effective in the long term management of the disease.

Medical care of obese children and adolescents. APV: a standardised multicentre documentation derived to study initial presentation and cardiovascular risk factors in patients transferred to specialised treatment institutions.

UNLABELLED: So far in Europe, no studies have been published on the structuring of medical care for obese children and adolescents. Besides anthropometric parameters, evaluations of the cardiovascular risk factors hypertension, dyslipidaemia, impaired glucose metabolism and treatment modalities were documented in a standardised multicentre evaluation survey (APV) of 18 primarily outpatient and nine rehabilitation institutions. In total, 3837 children (aged 2-20 years) took part in the years 2000 up to March 2003, of whom 1985 were treated in outpatient institutions and 1852 in rehabilitation institutions. Of these children, 10% were overweight, 37% obese, 49% extremely obese and 4% of normal weight at initial presentation. The frequencies of diagnostic procedures performed and documented were low (measurement of blood pressure 43%, lipids 40%, glucose metabolism 21%). In the subgroup of obese children who were screened for cardiovascular risk factors, 23% suffered from hypertension, 11% displayed increased cholesterol, 9% increased low-density lipoprotein-cholesterol, 29% increased triglycerides, 11% decreased high-density lipoprotein-cholesterol and 6% had impaired glucose metabolism. CONCLUSION: Despite the high prevalence of cardiovascular risk factors in obese children and adolescents confirmed in this report, diagnostic procedures failed in a considerable percentage even in specialised treatment centres for obese children and adolescents. In future, the feedback based on standardised evaluation of diagnostic and treatment procedures should aim to improve the quality of medical care.
