Background: We examined fidelity and feasibility of implementation of COVID-19 preventive measures in schools, and explored associations between adherence to these measures and staff well-being, to inform policy on sustainable implementation and staff wellbeing. Methods: Surveys were conducted across 128 schools in England with 107 headteachers and 2698 staff-members with reference to autumn term 2020, examining school-level implementation of preventive measures, adherence, and teacher burnout (response rates for headteacher and staff surveys were 84% and 59%, respectively). Results: The median number of measures implemented in primary and secondary schools was 33 (range 23-41), and 32 (range 22-40), respectively; most measures presented challenges. No differences were found regarding number of measures implemented by school-level socio-economic disadvantage. High adherence was reported for staff wearing face-coverings, staff regularly washing their hands, (secondary only) desks facing forwards, and (primary only) increased cleaning of surfaces and student hand-washing. Adherence to most measures was reported as higher in primary than secondary schools. Over half of school leaders and 42% (517/1234) of other teaching staff suffered from high emotional exhaustion. Higher teacher-reported school-wide adherence with measures was consistently associated with lower burnout for leaders and other teaching staff. Conclusions: Findings indicate a tremendous effort in implementing preventive measures and an urgent need to support investments in improving teacher wellbeing.

BackgroundLower socioeconomic position usually portends worse health outcomes, but multiple studies have found that atopic dermatitis is associated with higher socioeconomic position. The nature of this relationship remains unclear.ObjectiveTo systematically review the literature on socioeconomic position and atopic dermatitis and determine whether the association varies by patient or study characteristics.MethodsA literature search was conducted in the PubMed and Embase databases. Individual-level studies addressing the association between all measures of socioeconomic position and the prevalence or incidence of atopic dermatitis were eligible for inclusion. Two independent reviewers screened all texts and extracted all data for qualitative synthesis.ResultsEighty-eight studies met the inclusion criteria. Of the 88 studies, 42% (37) found a positive association between atopic dermatitis and socioeconomic position, 15% (13) found a negative association, and 43% (38) found a null or inconsistent association. Studies conducted in Europe, among children, and based on self-report of eczema were more likely to find a positive association with socioeconomic position.LimitationsStudies varied both in terms of the measurement of socioeconomic position and the definition of atopic dermatitis, limiting quantitative synthesis.ConclusionThe evidence of a positive association between atopic dermatitis and socioeconomic position is not consistent.

ImportanceAtopic eczema is characterized by a heterogenous waxing and waning course, with variable age of onset and persistence of symptoms. Distinct patterns of disease activity such as early-onset/resolving and persistent disease have been identified throughout childhood; little is known about patterns into adulthood.ObjectiveThis study aimed to identify subtypes of atopic eczema based on patterns of disease activity through mid-adulthood, to examine whether early life risk factors and participant characteristics are associated with these subtypes, and to determine whether subtypes are associated with other atopic diseases and general health in mid-adulthood.Design, setting, and participantsThis study evaluated members of 2 population-based birth cohorts, the 1958 National Childhood Development Study (NCDS) and the 1970 British Cohort Study (BCS70). Participant data were collected over the period between 1958 and 2016. Data were analyzed over the period between 2018 and 2020.Main outcomes and measuresSubtypes of atopic eczema were identified based on self-reported atopic eczema period prevalence at multiple occasions. These subtypes were the outcome in models of early life characteristics and an exposure variable in models of midlife health.ResultsLatent class analysis identified 4 subtypes of atopic eczema with distinct patterns of disease activity among 15 939 individuals from the NCDS (51.4% male, 75.4% White) and 14 966 individuals from the BCS70 (51.6% male, 78.8% White): rare/no (88% to 91%), decreasing (4%), increasing (2% to 6%), and persistently high (2% to 3%) probability of reporting prevalent atopic eczema with age. Sex at birth and early life factors, including social class, region of residence, tobacco smoke exposure, and breastfeeding, predicted differences between the 3 atopic eczema subtypes and the infrequent/no atopic eczema group, but only female sex differentiated the high and decreasing probability subtypes (odds ratio [OR], 1.99; 95% CI, 1.66-2.38). Individuals in the high subtype were most likely to experience asthma and rhinitis, and those in the increasing subtype were at higher risk of poor self-reported general (OR, 1.29; 95% CI, 1.09-1.53) and mental (OR 1.45; 95% CI, 1.23-1.72) health in midlife.Conclusions and relevanceThe findings of this cohort study suggest that extending the window of observation beyond childhood may reveal clear subtypes of atopic eczema based on patterns of disease activity. A newly identified subtype with increasing probability of activity in adulthood warrants additional attention given observed associations with poor self-reported health in midlife.

ImportanceResearch has highlighted associations between atopic dermatitis (AD) and mental health conditions in adults. However, literature on the development of mental health comorbidities in children is limited despite the large burden of pediatric AD worldwide.ObjectiveTo examine the association between AD and internalizing behaviors and symptoms of depression at multiple points across childhood and adolescence and to explore potential mediating factors, including asthma/rhinitis, sleep, and inflammation.Design, setting, and participantsThis longitudinal, population-based birth cohort study included children followed up from birth for a mean (SD) duration of 10.0 (2.9) years from the UK Avon Longitudinal Study of Parents and Children. Data were collected from September 6, 1990, to December 31, 2009. Data were analyzed from August 30, 2019, to July 30, 2020.ExposuresAnnual period prevalence of AD assessed at 11 points from 6 months to 18 years of age, measured by standardized questions about flexural dermatitis.Main outcomes and measuresSymptoms of depression, measured using child-reported responses to the Short Moods and Feelings Questionnaire at 5 points from 10 to 18 years of age and internalizing behaviors, measured by maternal report of the Emotional Symptoms subscale of the Strength and Difficulties Questionnaire at 7 points from 4 to 16 years of age.ResultsAmong the 11 181 children included in the analysis (5721 male [51.2%]), the period prevalence of symptoms of depression ranged from 6.0% to 21.6%; for internalizing behaviors, from 10.4% to 16.0%. Although mild to moderate AD was not associated with symptoms of depression, it was associated with internalizing behaviors as early as 4 years of age (mean increased odds of 29%-84% across childhood in adjusted models). Severe AD was associated with symptoms of depression (adjusted odds ratio, 2.38; 95% CI, 1.21-4.72) and internalizing symptoms (adjusted odds ratio, 1.90; 95% CI, 1.14-3.16). Sleep quality mediated some of this association, but it was not explained by differences in sleep duration, asthma/rhinitis, or levels of inflammatory markers (interleukin 6 and C-reactive protein).Conclusions and relevanceWithin this population-based birth cohort study in the UK, severe AD was associated with symptoms of depression and internalizing behaviors throughout childhood and adolescence. Risk of internalizing symptoms was increased even for children with mild AD beginning early in childhood, highlighting the importance of behavioral and mental health awareness in this population.

BackgroundAtopic eczema is a common and debilitating condition associated with depression and anxiety, but the nature of this association remains unclear.ObjectiveTo explore the temporal relationship between atopic eczema and new depression/anxiety.MethodsThis matched cohort study used routinely collected data from the UK Clinical Practice Research Datalink, linked to hospital admissions data. We identified adults with atopic eczema (1998-2016) using a validated algorithm, and up to 5 individuals without atopic eczema matched on date of diagnosis, age, sex, and general practice. We estimated the hazard ratio (HR) for new depression/anxiety using stratified Cox regression to account for age, sex, calendar period, Index of Multiple Deprivation, glucocorticoid treatment, obesity, smoking, and harmful alcohol use.ResultsWe identified 526,808 adults with atopic eczema who were matched to 2,569,030 without. Atopic eczema was associated with increased incidence of new depression (HR, 1.14; 99% CI, 1.12-1.16) and anxiety (HR, 1.17; 99% CI, 1.14-1.19). We observed a stronger effect of atopic eczema on depression with increasing atopic eczema severity (HR [99% CI] compared with no atopic eczema: mild, 1.10 [1.08-1.13]; moderate, 1.19 [1.15-1.23]; and severe, 1.26 [1.17-1.37]). A dose-response association, however, was less apparent for new anxiety diagnosis (HR [99% CI] compared with no atopic eczema: mild, 1.14 [1.11-1.18]; moderate, 1.21 [1.17-1.26]; and severe, 1.15; [1.05-1.25]).ConclusionsAdults with atopic eczema are more likely to develop new depression and anxiety. For depression, we observed a dose-response relationship with atopic eczema severity.

We examined the feasibility of implementing preventive measures to prevent SARS-CoV-2 transmission across 105 English primary schools in summer 2020 via a survey and interviews with headteachers. High rates of implementation of most recommended measures were noted with the exception of requiring 2 m distance for students, fitting hand sanitizers in classrooms and introducing one-way systems in school corridors. Measures such as regular handwashing and stopping assemblies were considered easy to implement. Majorly challenging measures included distancing between individuals (for students: 51%, N = 99; for staff: 34%; N = 98; for parents: 26%, N = 100), spacing out desks (34%, N = 99), keeping same staff assigned to each student group (33%, N = 97) and staggering break times (25%, N = 99). Rapid implementation was facilitated by staff commitment and communication among stakeholders, but hampered by limitations with guidance received, physical environments, resources, parental adherence and balancing preventive measures with learning. Difficulties with distancing for younger children suggest that smaller bubbles with fewer distancing requirements within these may be a policy option. Schools require further financial, human resource and other support for effective implementation of preventive measures.

BackgroundAtopic eczema onset is described primarily in early childhood, and the frequency and characteristics of adult-onset disease remain controversial.ObjectiveWe sought to determine the proportion of subjects who report atopic eczema symptoms between birth and midadulthood and to examine demographic, immunologic, and genetic factors associated with period of symptom onset.MethodsWe conducted a longitudinal study using data from 2 nationally representative community-based birth cohorts from the United Kingdom: the British Cohort Studies 1958 and 1970. Subjects were followed from birth through age 42 to 50 years. The primary outcome was the age period of self-reported atopic eczema symptom onset based on repeated measures of self-reported atopic eczema at each survey wave.ResultsThe annual period prevalence of atopic eczema ranged from 5% to 15% in 2 cohorts of more than 17,000 participants each followed from birth through middle age. There was no clear trend in prevalence by age, and among adults reporting active atopic eczema during a given year, only 38% had symptom onset reported in childhood. When compared with subjects whose eczema started in childhood, those with adult-onset disease were more likely to be women, from Scotland or Northern England, of lower childhood socioeconomic group, smokers in adulthood, and less likely to have a history of asthma. In a subanalysis using data from the 1958 cohort only, genetic mutations previously associated with atopic eczema, including filaggrin-null mutations, and allergen-specific IgE were more common among those with childhood-onset disease.ConclusionRates of self-reported atopic eczema remain high after childhood, and adult-onset atopic eczema has different risk factor associations than childhood-onset eczema.

BackgroundAtopic eczema is a common inflammatory skin disease. Various inflammatory conditions have been linked to cardiovascular disease, a major cause of global mortality and morbidity.ObjectiveWe sought to systematically review and meta-analyze population-based studies assessing associations between atopic eczema and specific cardiovascular outcomes.MethodsMEDLINE, Embase, and Global Health were searched from inception to December 2017. We obtained pooled estimates using random-effects meta-analyses. We used a multivariate Bayesian meta-regression model to estimate the slope of effect of increasing atopic eczema severity on cardiovascular outcomes.ResultsNineteen relevant studies were included. The effects of atopic eczema reported in cross-sectional studies were heterogeneous, with no evidence for pooled associations with angina, myocardial infarction, heart failure, or stroke. In cohort studies atopic eczema was associated with increased risk of myocardial infarction (n = 4; relative risk [RR], 1.12; 95% CI, 1.00-1.25), stroke (n = 4; RR, 1.10; 95% CI, 1.03-1.17), ischemic stroke n = 4; RR, 1.17; 95% CI, 1.14-1.20), angina (n = 2; RR, 1.18; 95% CI, 1.13-1.24), and heart failure (n = 2; RR, 1.26; 95% CI, 1.05-1.51). Prediction intervals were wide for myocardial infarction and stroke. The risk of cardiovascular outcomes appeared to increase with increasing severity (mean RR increase between severity categories, 1.15; 95% credibility interval, 1.09-1.21; uncertainty interval, 1.04-1.28).ConclusionSignificant associations with cardiovascular outcomes were more common in cohort studies but with considerable between-study heterogeneity. Increasing atopic eczema severity was associated with increased risk of cardiovascular outcomes. Improved awareness among stakeholders regarding this small but significant association is warranted.

ImportanceThe well-being and development of children is strongly influenced by parents' physical and psychosocial health. Data from small, clinic-based studies suggest that sleep loss may be common in parents of children with atopic dermatitis (AD), but longitudinal population-based studies are lacking.ObjectivesTo compare sleep disturbances over time between mothers of children with and without AD and to determine whether these disturbances are associated with the child's disease severity and the child's sleep disturbances.Design, setting, and participantsIn the ongoing Avon Longitudinal Study of Parents and Children, all pregnant women residing in Avon, United Kingdom, with an expected delivery date between April 1, 1991, and December 31, 1992, were recruited. Analyses for this study, a secondary analysis of this cohort, were performed from September 2017 to September 2018. Mother-child pairs were followed up with a time-varying measure of child AD activity and severity and self-reported maternal sleep measures repeated at multiple time points between child ages 6 months and 11 years.Main outcomes and measuresTime-varying binary measures of maternal sleep duration (

More severe atopic dermatitis and psoriasis are associated with a higher cumulative impact on quality of life, multimorbidity and healthcare costs. Proactive, early intervention in those most at risk of severe disease may reduce this cumulative burden and modify the disease trajectory to limit progression. The lack of reliable biomarkers for this at-risk group represents a barrier to such a paradigm shift in practice. To expedite discovery and validation, the BIOMarkers in Atopic Dermatitis and Psoriasis (BIOMAP) consortium (a large-scale European, interdisciplinary research initiative) has curated clinical and molecular data across diverse study designs and sources including cross-sectional and cohort studies (small-scale studies through to large multicentre registries), clinical trials, electronic health records and large-scale population-based biobanks. We map all dataset disease severity instruments and measures to three key domains (symptoms, inflammatory activity and disease course), and describe important codependencies and relationships across variables and domains. We prioritize definitions for more severe disease with reference to international consensus, reference standards and/or expert opinion. Key factors to consider when analysing datasets across these diverse study types include explicit early consideration of biomarker purpose and clinical context, candidate biomarkers associated with disease severity at a particular point in time and over time and how they are related, taking the stage of biomarker development into account when selecting disease severity measures for analyses, and validating biomarker associations with disease severity outcomes using both physician- and patient-reported measures and across domains. The outputs from this exercise will ensure coherence and focus across the BIOMAP consortium so that mechanistic insights and biomarkers are clinically relevant, patient-centric and more generalizable to current and future research efforts.

Background Atopic dermatitis (AD) is a common inflammatory disease of the skin that begins early in life and can be lifelong. The purpose of our study was to evaluate whether fetal exposure and/or early-life exposure of a child to antibiotics increases the risk of early-onset AD. Objectives We hypothesize that antibiotic exposure in utero or early in life (e.g. first 90 days) increases the likelihood that children develop AD. Methods Utilizing a large, prospectively collected electronic medical records database, we studied the association of antibiotic exposure received in utero or very early in life and the relative risk of onset of AD in a population-based cohort study. Associations were estimated using proportional hazards models as hazard ratios (HRs) with 95% confidence intervals (CIs). Results The risk of AD in childhood was increased after in utero or early-life antibiotic exposure. For any in utero antibiotic exposure the HR (CI) was 1.38 (1.36–1.39). However, penicillin demonstrated the strongest association with AD for both in utero exposure [1.43 (1.41–1.44)] and for childhood exposure [1.81 (1.79–1.82)]. HRs were higher in children born to mothers without AD than in those with AD pointing to effect modification by maternal AD status. Conclusions Children born to mothers exposed to antibiotics while in utero had, depending on the mother's history of AD, approximately a 20–40% increased risk of developing AD. Depending on the antibiotic, children who received antibiotics early in life had a 40–80% increased risk of developing AD. Our study supports and refines the association between incident AD and antibiotic administration. It also adds population-based support to therapeutic attempts to treat AD by modifying the skin microbiome. [ABSTRACT FROM AUTHOR]

IntroductionAtopic dermatitis is a complex disease with differing clinical presentations. Many attempts have been made to identify uniform subtypes, or phenotypes, of atopic dermatitis in order to identify different aetiologies, improve diagnosis, estimate more accurate clinical prognoses, inform treatment andmanagement or predict treatment efficacy andeffectiveness. However, no consensus yet exists on exactly what defines these phenotypes or how many there are and whether they are genuine or statistical artefacts. This review aims to identify previously reported phenotypes of atopic dermatitis, the features used to define them and any characteristics or clinical outcomes significantly associated with them.Methods and analysisWe will search Ovid Embase, Ovid MEDLINE and Web of Science from inception to the latest available date at the time of the search for studies attempting to classify atopic dermatitis in humans using any cross-sectional or longitudinal epidemiological or interventional design. Primary outcomes are atopic dermatitis phenotypes, features used to define them and characteristics associated with them in subsequent analyses. A secondary outcome is the methodological approach used to derive them. Two reviewers will independently screen titles and abstracts for inclusion, extract data and assess study quality. We will present the results of this review descriptively and with frequencies where possible.Ethics and disseminationEthical approval is not required for this study as it is a systematic review. We will report results from this systematic review in a peer-reviewed journal. The main value of this study will be to inform further research.Prospero registration numberCRD42018087500.

IntroductionChronic inflammatory diseases such as eczema (also known as atopic dermatitis) have been inconsistently linked to cardiovascular disease and stroke in both mechanistic and epidemiological studies. There is a need to review the existing epidemiological data examining the association between eczema and major cardiovascular outcomes, including angina, myocardial infarction, coronary revascularisation, heart failure, cardiac arrhythmias, stroke and cardiovascular death, in order to improve our understanding of the comorbidities of eczema.Methods and analysisWe will systematically review population-based studies, including cohort, case-control and cross-sectional studies, reporting on the association between eczema and cardiovascular outcomes. We will search Medline, Embase and Global Health, from their date of inception to April 2017, using a comprehensive search strategy formulated with the help of a librarian. Two reviewers will independently screen titles and abstracts in duplicate, followed by independent data extraction and quality assessment. We will group studies by the cardiovascular outcome under study and synthesise them narratively. If sufficient numbers of homogeneous studies are returned, we will perform meta-analyses to obtain pooled effect estimates. Preferred Reporting Items for Systematic Review and Meta-Analysis will be used to inform the reporting of this study.Trial registration numberCRD42017060359.

Atopic dermatitis (AD) is a chronic, relapsing condition, meaning that the intensity of symptoms usually fluctuates over time. Changes in skin physiology may be evident from birth, suggesting that AD may be a lifelong condition marked by intermittent symptoms/disease activity. Methodological considerations for studying the long-term course of AD are reviewed in detail. Improved measurement of the frequency and duration of active disease periods can help to elucidate more about the clinical course AD and the role of treatment in long-term outcomes.

Background: Two online behavioural interventions (one website for parents/carers of children with eczema; and one for young people with eczema) have been shown in randomised controlled trials to facilitate a sustained improvement in eczema severity. Aim: To describe intervention use and examine potential mediators of intervention outcomes and contextual factors that may influence intervention delivery and outcomes. Design and setting: Quantitative process evaluation in UK primary care. Method: Parents/carers and young people were recruited through primary care. Intervention use was recorded and summarised descriptively. Logistic regression explored sociodemographic and other factors associated with intervention engagement. Mediation analysis investigated whether patient enablement (ability to understand and cope with health issues), treatment use, and barriers to adherence were mediators of intervention effect. Subgroup analysis compared intervention effects among pre-specified participant subsets. Results: A total of 340 parents/carers and 337 young people were recruited. Most parents/carers (87%, n = 148/171) and young people (91%, n = 153/168) in the intervention group viewed the core introduction by 24 weeks. At 24 weeks, users had spent approximately 20 minutes on average on the interventions. Among parents/carers, greater intervention engagement was associated with higher education levels, uncertainty about carrying out treatments, and doubts about treatment efficacy at baseline. Among young people, higher intervention use was associated with higher baseline eczema severity. Patient enablement (the ability to understand and cope with health issues) accounted for approximately 30% of the intervention effect among parents/carers and 50% among young people. Conclusion: This study demonstrated that positive intervention outcomes depended on a modest time commitment from users. This provides further support that the wider implementation of Eczema Care Online is justified. [ABSTRACT FROM AUTHOR]

BackgroundCase reports and cross-sectional studies suggest increased risks of cutaneous and non-cutaneous infections in eczema; this relationship needs to be assessed in large population-based studies with diagnostic confirmation. The objective was to examine associations between eczema and common childhood infections.MethodsIndividuals registered prior to age 18 in the Health Improvement Network, a UK general practice database, from 2003 to 2013 were included in this cohort study. We determined the association between eczema and selected infectious outcomes, including cutaneous (dermatophyte, herpes simplex virus, impetigo, molluscum contagiosum and warts), and non-cutaneous infections (otitis media, streptococcal throat infections, and pneumonia).ResultsEczema was diagnosed in 14.4% (95% confidence interval 14.4, 14.4), and the average age of eczema diagnosis was 7.94 years (7.91, 7.98). All of the infectious illnesses were more prevalent in those with eczema compared to those without, with adjusted odds ratios (95% confidence intervals) as follows: dermatophyte 2.54 (2.47-2.61), herpes simplex virus, 2.08 (2.04-2.12), impetigo 2.61 (2.53-2.68), molluscum contagiosum 3.11 (3.07-3.14) and warts 1.98 (1.96-2.00). For non-cutaneous outcomes, the odds of otitis media, streptococcal throat infections and pneumonia were 2.24 (2.22-2.25), 1.75 (1.69-1.82) and 1.27 (1.23,1.31). Associations were attenuated in sensitivity analyses.ConclusionSelected infectious illnesses were more prevalent in those with eczema versus those without, with the strength of association varying from 75% increase in streptococcal throat infections to a three-fold increased prevalence for molluscum contagiosum. Findings suggest there may be generalized immune dysfunction in eczema predisposing to increased risk of various infections, which is important for clinical management
