The Environmental Effects Assessment Panel of the Montreal Protocol under the United Nations Environment Programme evaluates effects on the environment and human health that arise from changes in the stratospheric ozone layer and concomitant variations in ultraviolet (UV) radiation at the Earth’s surface. The current update is based on scientific advances that have accumulated since our last assessment (Photochem and Photobiol Sci 20(1):1–67, 2021). We also discuss how climate change affects stratospheric ozone depletion and ultraviolet radiation, and how stratospheric ozone depletion affects climate change. The resulting interlinking effects of stratospheric ozone depletion, UV radiation, and climate change are assessed in terms of air quality, carbon sinks, ecosystems, human health, and natural and synthetic materials. We further highlight potential impacts on the biosphere from extreme climate events that are occurring with increasing frequency as a consequence of climate change. These and other interactive effects are examined with respect to the benefits that the Montreal Protocol and its Amendments are providing to life on Earth by controlling the production of various substances that contribute to both stratospheric ozone depletion and climate change.

Background Allergic diseases often develop jointly during early childhood but differ in timing of onset, remission and progression. Their disease course over time is often difficult to predict and determinants are not well understood. Objectives We aimed to identify trajectories of allergic diseases up to adolescence and to investigate their association with early-life and genetic determinants and clinical characteristics. Methods Longitudinal k-means clustering was used to derive trajectories of allergic diseases (asthma, atopic dermatitis and rhinitis) in two German birth cohorts (GINIplus/LISA). Associations with early-life determinants, polygenic risk scores, food and aeroallergen sensitization and lung function were estimated by multinomial models. Results were replicated in the independent Swedish BAMSE cohort. Results Seven allergic disease trajectories were identified: “Intermittently allergic”, “rhinitis”, “early-resolving dermatitis”, “mid-persisting dermatitis”, “multimorbid”, “persisting dermatitis plus rhinitis” and “early-transient asthma”. Family history of allergies was more prevalent in all allergic disease trajectories compared the non-allergic controls with stronger effect sizes for clusters comprising more than one allergic disease (e.g. RRR=5.0, 95%CI=[3.1–8.0] in the multimorbid versus 1.8[1.4–2.4] in the mild intermittently allergic cluster). Specific polygenic risk scores for single allergic diseases were significantly associated with their relevant trajectories. The derived trajectories and their association with genetic effects and clinical characteristics showed similar results in BAMSE. Conclusion Seven robust allergic clusters were identified and showed associations with early life and genetic factors as well as clinical characteristics.

Background Dietary carbohydrates and fats are intrinsically correlated within the habitual diet. We aimed to disentangle the associations of starch and sucrose from those of fat, in relation to allergic sensitization, asthma and rhinoconjuctivitis prevalence in humans, and to investigate underlying mechanisms using murine models. Methods Epidemiological data from participants of two German birth cohorts (age 15) were used in logistic regression analyses testing cross-sectional associations of starch and sucrose (and their main dietary sources) with aeroallergen sensitization, asthma and rhinoconjunctivitis, adjusting for correlated fats (saturated, monounsaturated, omega-6 and omega-3 polyunsaturated) and other covariates. For mechanistic insights, murine models of aeroallergen-induced allergic airway inflammation (AAI) fed with a low-fat-high-sucrose or -high-starch versus a high-fat diet were used to characterize and quantify disease development. Metabolic and physiologic parameters were used to track outcomes of dietary interventions and cellular and molecular responses to monitor the development of AAI. Oxidative stress biomarkers were measured in murine sera or lung homogenates. Results We demonstrate a direct association of dietary sucrose with asthma prevalence in males, while starch was associated with higher asthma prevalence in females. In mice, high-carbohydrate feeding, despite scant metabolic effects, aggravated AAI compared to high-fat in both sexes, as displayed by humoral response, mucus hypersecretion, lung inflammatory cell infiltration and TH2-TH17 profiles. Compared to high-fat, high-carbohydrate intake was associated with increased pulmonary oxidative stress, signals of metabolic switch to glycolysis and decreased systemic anti-oxidative capacity. Conclusion High consumption of digestible carbohydrates is associated with increased prevalence of asthma in humans and aggravated lung allergic inflammation in mice, involving oxidative stress-related

ObjectiveThis study aimed to assess the association of changes in sleep behaviors from adolescence to young adulthood with the risk of overweight/obesity, and the reverse relationship.MethodsData of 1978 participants was obtained from the 15- and 20-year follow-ups of the GINIplus and LISA birth cohorts. Insufficient sleep was defined as reported sleep duration <8 h for adolescents, <7 h for adults, and sleep difficulties as reported having sleeping difficulties. Logistic regression models were used to assess bidirectional associations of changes in insufficient sleep and sleep difficulties with overweight/obesity. The polygenic risk scores (PRS) for body mass index (BMI) was tested in a sub-sample (n = 918).ResultsCompared with sufficient sleep in both adolescence and young adulthood, insufficient sleep only in young adulthood was associated with an increased risk of overweight/obesity (odds ratio = 1.85, 95%confidence interval = [1.27–2.69]). Compared with no sleep difficulties at both time-points, only persistent sleep difficulties was associated with a higher risk of overweight/obesity (2.15 [1.22–3.77]). The PRS for BMI was associated with overweight/obesity (1.41 [1.17–1.70]), but no significant gene-sleep interaction effect was observed. Reversely, only persistent overweight/obesity was associated with increased risks of insufficient sleep (1.81 [1.21–2.70]), and sleep difficulties (1.77 [1.18–2.66]), respectively.ConclusionsInsufficient sleep only presented a cross-sectional association with overweight/obesity in young adulthood, while long-term sleep difficulties from adolescence to young adulthood was associated with young adult overweight/obesity. Reversely, long-term overweight/obesity from adolescence to young adulthood was associated with insufficient sleep and sleep difficulties in young adulthood.

Background/objectives The transition to adolescence is characterised by considerable behavioural changes, including diet. This study describes the level of obesogenic eating behaviours in 10- and 15-year-olds, and their association with dietary intake. Subjects/methods Participants of the 10- and 15-year follow-ups of the German GINIplus and LISA birth cohort studies were included (N-10 = 2257; N-15 = 1880). Eating behaviours and dietary intake were assessed via self-report questionnaires. Sex-stratified, cross-sectional associations of "external eating", "emotional eating" and "dietary restraint" (the latter at age 15 years only) with dietary intake (17 food groups-categorised into tertiles, macronutrients, and total energy) were assessed using multinomial logistic or multiple linear regression as required, adjusting for covariates and correcting for multiple testing. Results Reported levels of eating behaviours were low in both age-groups. External eating was higher in 10-year-old males than females, while all eating behaviours were most pronounced in 15-year-old females. At 10 years, emotional eating was associated with medium vegetable intake in females (Relative Risk Ratio (RRR) = 1.84, p = 0.0017). At 15 years, external eating was associated with total energy (kJ) in females (beta = 718, p = 0.0002) and high butter intake in males (RRR = 1.96, p = 0.0019). Dietary restraint in females was inversely associated with total energy (beta = -967, p < 0.0001) and omega-3 fatty acids (Means Ratio (MR) = 0.94, p = 0.0017), and positively associated with high fruit (RRR = 2.20, p = 0.0003) and whole grains (RRR = 1.94, p = 0.0013). Conclusion Obesogenic eating behaviour scores are low among children and adolescents of a predominantly high socioeconomic status population and present only few associations with specific aspects of diet, mainly among adolescent females.

Introduction Depressive symptoms are highly prevalent in adolescence, highlighting the need for early identification of precursors. Research into psychopathological symptoms predicting depressive psychopathology in adolescents is therefore of great relevance. Moreover, given that the prevalence of depressive symptomatology in adolescence shows marked differences between girls and boys, insight into potential sex-specific differences in precursors is important. Methods This study examined the relationships between emotional problems, conduct problems, hyperactivity/inattention, peer problems, and difficulties in prosocial behaviour at age 10 (Strengths and Difficulties Questionnaire), and the presence of depressive symptoms at age 15 (Depression Screener for Teenagers). Using data from 2824 participants of the GINIplus and LISA birth cohorts, the association of each SDQ subscale at age 10 years with the presence of depressive symptoms at age 15 years was analyzed using sex-specific logistic regression, adjusting for potential confounders. Results Emotional problems [odds ratio (OR) 1.99, p = 0.002 for boys and OR 1.77, p < 0.001 for girls] and peer problems (OR 2.62, p < 0.001 for boys, OR 1.91, p = 0.001 for girls) at age 10 showed an increased risk for the presence of depressive symptoms at age 15. Additionally, boys with conduct problems at age 10 were at greater risk of showing depressive symptoms in adolescence (OR 2.50, p < 0.001). Discussion Based on the identified prospective relationships in our study, it might be of particular importance to tailor prevention approaches during childhood to peer and emotional problems to reduce the risk of depressive psychopathology in adolescence. Moreover, particularly in boys, it seems important to also target conduct problems in childhood as a precursor of depressive symptoms in the adolescent period.

Background A large multicentre European study reported later onset of menopause among women residing in greener areas. This influence on the timing of a reproductive event like menopause, raises the question whether similar associations can be observed with timing of menarche. We investigated whether exposure to residential green space was related to the age at menarche in German and Australian adolescent girls. Methods The analytic samples comprised of 1706 German and 1474 Australian adolescent girls. Percentage of green space was calculated in 1000 m buffers around a residential address or its surrogate at the previous follow-up. Mixed effects Cox proportional hazard models were used to explore the associations. The survival object was the occurrence of menarche at the time of follow-up (15-year follow-up of the German cohorts and the study wave at 14–15 years in the Australian cohort) and number of years since baseline (10-year follow-up in the German cohort and the study wave at 10–11 years in the Australian cohort). Participants who did not reach menarche were included as censored observations. Results A greener residence was not associated with the age at menarche. Null findings were consistent in the general population and in analyses stratified by socioeconomic status or urbanicity in both countries. Urban residents were more likely to have earlier menarche, and this association was consistent across Germany and Australia. Conclusion The results of our analysis do not support the hypothesis that residing in places with more green space can influence timing of menarche. However, given the limitations of our study, researchers should not be discouraged to further explore environmental risk factors of early menarche.

This assessment by the Environmental Effects Assessment Panel (EEAP) of the United Nations Environment Programme (UNEP) provides the latest scientific update since our most recent comprehensive assessment (Photochemical and Photobiological Sciences, 2019, 18, 595–828). The interactive effects between the stratospheric ozone layer, solar ultraviolet (UV) radiation, and climate change are presented within the framework of the Montreal Protocol and the United Nations Sustainable Development Goals. We address how these global environmental changes affect the atmosphere and air quality; human health; terrestrial and aquatic ecosystems; biogeochemical cycles; and materials used in outdoor construction, solar energy technologies, and fabrics. In many cases, there is a growing influence from changes in seasonality and extreme events due to climate change. Additionally, we assess the transmission and environmental effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is responsible for the COVID-19 pandemic, in the context of linkages with solar UV radiation and the Montreal Protocol.

Electronic data capture (EDC) is an important tool for the digitalisation of paper-based documents such as questionnaires and for the identification of errors before values are finally saved in a database. The data acquisition software TeleForm is one example for an EDC system which is used to digitise paper-based documents. TeleForm checks the data of the scanned document and gives indications of possibly incorrectly read data. In the German National Cohort (GNC) this software is among other things applied to digitalise questionnaires.The following questions are addressed in this article: Is the scan workflow referring to the questionnaires in the GNC and in particular the data acquisition software TeleForm (with the settings chosen for the GNC) reliable? How much loss of data quality is acceptable to reduce the amount of work? Can artificial intelligence replace human inspection sufficiently or will the latter continue to play an indispensable role in the scan workflow of the GNC in the future? By answering these questions, the strengths and the limitations of the scan workflow in the GNC using the TeleForm software will be discussed.The current work uses data collected in the GNC centre in Dusseldorf. 300 questionnaires on physical activity were validated and checked twice, first by the system TeleForm and second by a visual assessment. The data acquisition software TeleForm shows high error rates in interpreting free text fields as well as in reading handwritten numbers. Especially the digit "0" was misinterpreted most often.In order to save time and thus make work easier, some shortcomings must be remedied. This can be achieved, for example, by putting special emphasis on the expansion of the reading areas of TeleForm and on the improved reproduction and reading of numerical values., Die elektronische Datenerfassung (EDC) ist ein wichtiges Instrument zur Digitalisierung von papierbasierten Dokumenten wie beispielsweise Fragebögen. Ebenso ist es für die Identifizierung von Fehlern hilfreich, bevor die Werte endgültig in einer Datenbank gespeichert werden. Die Datenerfassungssoftware TeleForm ist ein Beispiel für ein EDC-System, das zur Digitalisierung von papierbasierten Dokumenten eingesetzt wird. TeleForm prüft die Daten des eingescannten Dokumentes und gibt Hinweise auf möglicherweise fehlerhaft gelesene Daten. In der NAKO Gesundheitsstudie wird diese Software unter anderem zur Digitalisierung von Fragebögen eingesetzt.In diesem Artikel werden die folgenden Fragen behandelt: Ist der Scan-Workflow bezogen auf die Fragebögen in der NAKO Gesundheitsstudie und insbesondere die Datenerfassungssoftware TeleForm (mit den für die NAKO gewählten Einstellungen) zuverlässig? Wieviel Verlust an Datenqualität ist akzeptabel, um den Arbeitsaufwand zu reduzieren? Kann künstliche Intelligenz die menschliche Überprüfung ausreichend ersetzen oder wird letztere auch in Zukunft eine unverzichtbare Rolle im Scan-Workflow der NAKO spielen? Durch die Beantwortung dieser Fragen sollen die Stärken und Grenzen des Scan-Workflows in der NAKO Gesundheitsstudie unter Verwendung der TeleForm-Software diskutiert werden.Die aktuelle Arbeit verwendet Daten, die im NAKO-Zentrum in Düsseldorf erhoben wurden. 300 Fragebögen zur körperlichen Aktivität wurden validiert und zweimal überprüft, zum einen durch das System TeleForm und zum anderen durch eine visuelle Kontrolle. Die Datenerfassungssoftware TeleForm zeigt hohe Fehlerquoten bei der Interpretation von Freitextfeldern sowie beim Lesen von handgeschriebenen Zahlen. Insbesondere die Ziffer "0" wurde am häufigsten falsch interpretiert.Um Zeit zu sparen und damit die Arbeit zu erleichtern, müssen einige Defizite behoben werden. Dies kann zum Beispiel durch die Erweiterung der Lesebereiche sowie die Verbesserung des Lesens von Z

Background Lipid mediators derived from omega-6 and omega-3 polyunsaturated fatty acids (PUFA) contribute to the regulation of inflammatory processes in the lung. Adolescence represents an important stage of lung growth, and modifying the availability of PUFA through diet might hold potential for improved lung function. However, effects may depend on individual differences in PUFA metabolism. We assessed the association of rich sources of dietary PUFA with lung function in adolescents, and evaluated the modifying role of 17 single nucleotide polymorphisms (SNP) in the FADS gene cluster involved in PUFA metabolism.Methods 1931 participants of the 15-year follow-up of the GINIplus and LISA birth cohort studies, with data on dietary intake (food-frequency questionnaire), spirometry, and genotyped SNPs of the FADS cluster, were included. Cross-sectional associations of rich dietary sources of omega-6 (margarine) and omega-3 (oily fish) PUFA with lung function z-scores (FVC and FEV1), were assessed by linear regression, adjusting for covariates (sex, age, height, BMI, parental education, asthma, daily calories). Genotypes were coded following an additive model (minor allele count: 0/1/2). Interactions between dietary PUFA and each SNP were independently tested. Following a significant interaction, analyses were additionally stratified by the relevant SNP genotype. Correction for multiple testing was performed according to Nyholt.Results Mean GLI z-scores of FVC and FEV1 were -0.51 and -0.54, respectively. Margarine and oily fish each represented <1% of daily caloric intake. No significant cross-sectional associations were observed between these sources of PUFA and lung function. Although a single nominal effect was found for the interaction between oily fish and rs174449, with respect to FVC (see figure 1 for the association of oily fish and FVC stratified by genotype), it was no longer significant after correction for multiple testing.

Background: The severity of facial telangiectasia or red veins is associated with many lifestyle factors. However, the genetic predisposition remains unclear. Objectives: We performed a genome-wide association study (GWAS) on facial telangiectasia in the Rotterdam Study (RS) and tested for replication in two independent cohorts. Additionally, a candidate gene approach with known pigmentation genes was performed. Methods: Facial telangiectasia were extracted from standardized facial photographs (collected from 2010–2013) of 2842 northwestern European participants (median age 66.9, 56.8% female) from the RS. Our GWAS top hits (P-value <10−6) were tested for replication in 460 elderly women of the SALIA cohort and in 576 additional men and women of the RS. Associations of top single nucleotide polymorphisms (SNPs) with expression quantitative trait loci (eQTL) in various tissues were reviewed (GTEx database) alongside phenotype associations in the UK biobank database. SNP-based associations between known pigmentation genes and facial telangiectasia were tested. Conditional analysis on skin colour was additionally performed. Results: Our most significant GWAS signal was rs4417318 (P-value 5.38*10−7), an intergenic SNP on chromosome 12 mapping to the SLC16A7 gene. Other suggestive SNPs tagged genes ZNF211, ZSCAN4, ICOS and KCNN3; SNP eQTLs and phenotype associations tagged links to the vascular system. However, the top signals did not pass significance in the two replication cohorts. The pigmentation genes KIAA0930, SLCA45A2 and MC1R, were significantly associated with telangiectasia in a candidate gene approach but not independently of skin colour. Conclusion: In this GWAS on telangiectasia in a northwestern European population, no genome-wide significant SNPs were found, although suggestive signals indicate genes involved in the vascular system might be involved in telangiectasia. Significantly associated pigmentation genes underline the lin
