Remote Assessment of Eczema Severity via AI-powered Skin Image Analytics: A Systematic Review.

Various studies have been published on the remote assessment of eczema severity from digital camera images. Successful deployment of an accurate and robust AI-powered tool for such purposes can aid the formulation of eczema treatment plans and assist in patient monitoring. This review aims to provide an overview of the quality of published studies on this topic and to identify challenges and suggestions to improve the robustness and reliability of existing tools. We identified 25 articles from the Scopus database that aimed to assess eczema severity automatically from digital camera images by eczema area detection (n=13), which is important for prior delineation of the most relevant clinical features, and/or severity prediction (n=12). Deep learning methods (n=14) were more commonly used in recent years over conventional machine learning (n=11). A set of 20 pre-defined criteria were used for critical appraisal in this study. Study quality was hindered in many cases due to dataset challenges, with only 28% of studies reporting patient age range and 16% reporting skin phototype range. Furthermore, 52% of studies utilised solely non-public datasets and only 17% provided open-source access to code repositories, making validation of experimental results a significant challenge. In terms of algorithm design, attempts to improve model accuracy and process automation are widely reported. However, there remains limited implementation of methods for explicitly improving model trustworthiness and robustness. There is a need for a high-quality dataset with a sufficient number of bias-free images and consistent labels, as well as improved image analytics methods, to enhance the state of remote eczema severity assessment algorithms. Improving the interpretability and explainability of developed tools will further improve long-term reliability and trustworthiness.

A practical toolbox for the effective transition of adolescents and young adults with asthma and allergies: An EAACI position paper.

INTRODUCTION: Adolescence is a critical stage of rapid biological, emotional and social change and development. Adolescents and young adults (AYA) with asthma and allergies need to develop the knowledge and skills to self-manage their health independently. Healthcare professionals (HCP), parents and their wider network play an essential role in supporting AYA in this process. Previous work showed significant limitations in transition care across Europe. In 2020, the first evidence-based guideline on effective transition for AYA with asthma and allergies was published by EAACI. AIM: We herein summarize practical resources to support this guideline's implementation in clinical practice. METHODS: For this purpose, multi-stakeholder Task Force members searched for resources in peer review journals and grey literature. These resources were included if relevant and of good quality and were pragmatically rated for their evidence-basis and user friendliness. RESULTS: Resources identified covered a range of topics and targeted healthcare professionals, AYA, parents/carers, schools, workplace and wider community. Most resources were in English, web-based and had limited evidence-basis. CONCLUSIONS: This position paper provides a valuable selection of practical resources for all stakeholders to support effective transitional care for AYA with asthma and allergies. Future research should focus on developing validated, patient-centred tools to further assist evidence-based transition care.

Perceptions of adolescents and young adults with allergy and/or asthma and their parents on EAACI guideline recommendations about transitional care: A European survey.

BACKGROUND: The European Academy of Allergy and Clinical Immunology has developed a guideline to provide evidence-based recommendations for healthcare professionals to support the transitional care of adolescents and young adults (AYA) with allergy and/or asthma. The goal of this work was to ensure that the draft recommendations are also important for patients. METHODS: We surveyed patients aged 11-25 years with allergy and/or asthma and their parents across Europe between 17 February and 16 March 2020. The multilingual survey was distributed through national allergy and asthma patient organizations in Europe as well as through social media. RESULTS: A total of 1210 responses from 24 European countries were collected. There were 415 (34.3%) AYA and 795 (65.7%) parents. The majority of AYA (72.3%) and parents (81.9%) were female. Patients had a history of asthma (61.1%), allergic rhinoconjunctivitis (54.1%), food allergy (53.8%), atopic eczema (42.6%) and anaphylaxis (28.8%). All recommendations achieved the median score of either 'important' or 'very important'. The least supported recommendations were the use of joint clinics with both paediatric and adult physicians attending and the use of web-based or mobile technologies for communication with the AYA. The most supported recommendation was checking that the AYA is knowledgeable and compliant with their prescribed medication. Qualitative analysis revealed conditional approval for some recommendations. CONCLUSIONS: There was agreement from patients and parents on the importance of the draft recommendations on transitional care for AYA with allergy and/or asthma and their parents. The recommendations now need to be implemented into clinical practice across Europe.

Current transition management of adolescents and young adults with allergy and asthma: a European survey.

BACKGROUND: Transition from parent-delivered to self-management is a vulnerable time for adolescents and young adults (AYA) with allergy and asthma. There is currently no European guideline available for healthcare professionals (HCPs) on transition of these patients and local/national protocols are also mostly lacking. METHODS: European HCPs working with AYA with allergy and asthma were invited to complete an online survey assessing challenges of working with these patients, current transition practices and access to specific healthcare resources. RESULTS: A total of 1179 responses from 41 European countries were collected. Most HCPs (86%) reported a lack of a transition guideline and a lack of a transition process (20% paediatric HCPs, 50% of adult HCPs, 56% HCP seeing all ages). Nearly half (48%) acknowledged a lack of an established feedback system between paediatric and adult medical services. Many respondents never routinely asked about mental health issues such as self-harm or depression and are not confident in asking about self-harm (66.6%), sexuality (64%) and depression (43.6%). The majority of HCPs (76%) had not received specific training in the care of AYA although 87% agreed that transition was important for AYA with allergy and asthma. CONCLUSION: Although there was agreement that transition is important for AYA with allergy and asthma, there are crucial limitations and variations in the current provision of transition services across Europe. Standardisation of AYA management and specific training are required. This should improve management and continuity of care during adolescence and into adulthood to achieve the best healthcare outcomes.

EAACI Guidelines on the effective transition of adolescents and young adults with allergy and asthma.

Adolescent and young adult (AYA) patients need additional support, while they experience the challenges associated with their age. They need specific training to learn the knowledge and skills required to confidently self-manage their allergies and/or asthma. Transitional care is a complex process, which should address the psychological, medical, educational and vocational needs of AYA in the developmentally appropriate way. The European Academy of Allergy and Clinical Immunology has developed a clinical practice guideline to provide evidence-based recommendations for healthcare professionals to support the transitional care of AYA with allergy and/or asthma. This guideline was developed by a multidisciplinary working panel of experts and patient representatives based on two recent systematic reviews. It sets out a series of general recommendations on operating a clinical service for AYA, which include the following: (a) starting transition early (11-13 years), (b) using a structured, multidisciplinary approach, (c) ensuring AYA fully understand their condition and have resources they can access, (d) active monitoring of adherence and (e) discussing any implications for further education and work. Specific allergy and asthma transition recommendations include (a) simplifying medication regimes and using reminders; (b) focusing on areas where AYA are not confident and involving peers in training AYA patients; (c) identifying and managing psychological and socio-economic issues impacting disease control and quality of life; (d) enrolling the family in assisting AYA to undertake self-management; and (e) encouraging AYA to let their friends know about their allergies and asthma. These recommendations may need to be adapted to fit into national healthcare systems.

The effectiveness of interventions to improve self-management for adolescents and young adults with allergic conditions: A systematic review.

BACKGROUND: This systematic review aimed to review the literature on interventions for improving self-management and well-being in adolescents and young adults (11-25 years) with asthma and allergic conditions. METHODS: A systematic literature search was undertaken across eight databases. References were checked by two reviewers for inclusion. Study data were extracted, and their quality was assessed in duplicate. A narrative synthesis was undertaken. RESULTS: A total of 30 papers reporting data from 27 studies were included. Interventions types were psychological (k = 9); e-health (k = 8); educational (k = 4); peer-led (k = 5); breathing re-training (k = 1). All interventions were for asthma. Psychological interventions resulted in significant improvements in the intervention group compared with the control group for self-esteem, quality of life, self-efficacy, coping strategies, mood and asthma symptoms. E-Health interventions reported significant improvements for inhaler technique, adherence and quality of life. General educational interventions demonstrated significantly improved quality of life, management of asthma symptoms, controller medication use, increased use of a written management plan and reduction in symptoms. The peer-led interventions included the Triple A (Adolescent Asthma Action) programme and a peer-led camp based on the Power Breathing Programme. Improvements were found for self-efficacy, school absenteeism and quality of life. CONCLUSION: Although significant improvements were seen for all intervention types, many were small feasibility or pilot studies, few studies reported effect sizes and no studies for allergic conditions other than asthma met the inclusion criteria. Research using large longitudinal interventional designs across the range of allergic conditions is required to strengthen the evidence base.

Understanding the challenges faced by adolescents and young adults with allergic conditions: A systematic review.

BACKGROUND: Adolescence represents a vulnerable time for individuals with asthma and allergic conditions. They suffer an unexpected degree of morbidity. This systematic review aimed to understand the challenges faced by adolescents and young adults with these conditions. METHODS: A systematic literature search was undertaken across eight databases. References were checked by two reviewers for inclusion. Study data were extracted, and their quality was assessed in duplicate. A narrative meta-synthesis was undertaken. RESULTS: A total of 108 papers describing 106 studies were retrieved, most focused on asthma. Five themes were identified across studies: (a) Health-related quality of life-impairment was associated with poor disease control, psychosocial issues, adolescent-onset allergic disease and female sex; (b) Psychological factors-asthma and food allergy were associated with anxiety and depression, atopic dermatitis was associated with suicidal ideation, and that parental emotional support may be protective; (c) Adherence-suboptimal adherence was associated with older age, barriers to medication usage, poor symptom perception and failure to take responsibility, and positive factors were routines, simpler treatment regimes, better knowledge and perceptions about medications; (d) Self-management-facilitated by education, knowledge and a positive attitude; and (e) Supportive relationships-families could modify barriers to adherence and foster positive views about self-management, adolescents suggested that their peers should be more involved in supporting them, and adolescents also wished to have support from nonjudgemental healthcare professionals. CONCLUSIONS: We have some understanding of the challenges faced by adolescents with asthma, less so for other allergic conditions. This knowledge will be used to support guidelines for managing adolescents.

Anxiety and stress in mothers of food-allergic children.

BACKGROUND: Previous reports suggest that parents especially mothers of food-allergic children may have increased anxiety. Studies with an appropriate control group have not been undertaken, and the determinants of such anxiety are not known. We compared measures of anxiety and stress in mothers of food-allergic children and atopic non-food-allergic children, with anxiety and stress in mothers of children with no chronic illness. METHODS: Cross-sectional study of mothers attending a hospital appointment for their 8- to 16-year-old child. Mothers of children with food allergy, asthma but no food allergy or no chronic illness completed questionnaires including State-Trait Anxiety Inventory, Perceived Stress Scale and measures of anxiety and psychologic adjustment in their child. RESULTS: Forty mothers of food-allergic children, 18 mothers of asthmatic children without food allergy and 38 mothers of children with no chronic illness (controls) were recruited. Mothers of food-allergic children showed increased state anxiety ­ median anxiety score 38.0 (IQR 30.0, 44.0) food allergy, 27.0 (22.0, 40.0) control p = 0.012; and increased stress ­ median stress score 18.5 (12.0, 22.0) food allergy, 14.0 (7.5, 19.5)control p = 0.035. No significant differences were seen between mothers in the asthmatic group and controls. In multivariate analysis, previous food anaphylaxis(p = 0.008) and poorly controlled asthma (p = 0.004) were associated with increased maternal anxiety. Child anxiety and adjustment did not differ between food-allergic and control groups. CONCLUSIONS: Mothers of food-allergic children have increased anxiety and stress compared with mothers of children with no chronic illness. Anaphylaxis and poorly controlled asthma are associated with maternal anxiety.

Dental problems and emergencies of trekkers--epidemiology and prevention. Results of the ADEMED Expedition 2008.

OBJECTIVE: Dental problems are rarely mentioned in the training of medical students or physicians in travel medicine, and there are little data on dental problems of travellers in the literature. We studied the epidemiology of dental problems amongst trekkers in Nepal to develop strategies for preventive care during/before travelling and propose a curriculum for dental First Aid training. MATERIAL AND METHODS: We undertook a prospective, cross-sectional questionnaire and clinical dental survey of Trekkers at Manang (3550 m, Annapurna Circuit, Nepal). The questionnaire was developed based on published literature and clinical experience (exploring: availability of dental kits, dental history, current dental problems, and nutritional behavior). Dental examination included: dental status, papillary bleeding index (PBI), and plaque index (Quigley and Hein; QH). Questionnaire and clinical findings were compared to data of the Annapurna Conservancy Authority about the number of days of trekkers in the region to estimate the incidence of dental problems of trekkers. RESULTS: None of the 309 participants carried a dental first aid kit. Dental problems, potentially treatable with a dental first aid kit, were reported by 50/309 (16.5%). Oral hygiene en route was significantly worse than home hygiene practice; overall increased plaque indices were found (Median QH: 2.25 in women; 2.36 in men). Participants who visited a dentist ≤6 months before departure had significantly fewer problems, and had lower PBI [males 0.07 (IQR 0.0 to 0.29), females 0.0 (IQR 0.0 to 0.11)]. Combining our findings with data of the park authorities on person days in the region (2007), we found a risk of dental problems as follows: any dental problem 1:23.7 trekking days; gingival bleeding 1:37.7 trekking days; dental pain 1:145.2 trekking days; lost fillings 1:339 trekking days; fractured teeth 1:509 trekking days. CONCLUSIONS: Dental problems can pose significant discomfort for anybody travelling in regions with low/missing infrastructure. Improved awareness regarding dental first aid is essential and physicians counseling travellers in preventive strategies should advise a dental checkup pre-departure. Dental first aid and emergency treatment in the field should be included in the training curricula in travel medicine for both undergraduate and postgraduate students.

High prevalence of food sensitisation in young children with liver disease: a clue to food allergy pathogenesis?

BACKGROUND: The pathogenesis of food allergy is not completely understood - animal models suggest hepatic mechanisms may be important for immune tolerance to orally ingested antigens, but there is little direct evidence for this in humans. OBJECTIVES: We investigated whether there is an association between liver dysfunction or transplantation in young children and IgE sensitisation to food. METHODS: We evaluated paired pre- and post- liver transplant sera from children aged 0-36 months treated at a single centre during 2001-2008. Sera were assayed for total IgE and cow's milk, egg and peanut-specific IgE. We quantified hepatic dysfunction pre-transplant using the Paediatric End-stage Liver Disease (PELD) score. We also assessed 70 children after renal transplant to establish whether any association between liver transplant and food sensitisation was organ specific. RESULTS: Paired sera were available from 50 of 94 children who had a liver transplant during the study period. 35 of 50 (70%) had IgE sensitisation (≥ 0.35 kUa/l) to ≥ 1 food pre-transplant and 18 (36%) post-transplant (p = 0.001). Ten (20%) children had food-specific IgE levels that carry high probability of challenge-confirmed food allergy pre-transplant. Food sensitisation pre-transplant was associated with severity of liver dysfunction [mean (s.d.) pre-transplant PELD score 1.52 (0.13) in food sensitised, 0.77 (0.22) in non-sensitised children p = 0.004]. Total IgE level was raised in 34/42 (81%) pre-transplant and fell significantly post-transplant. Interview assessment of the parents of 40 children revealed that 13 (33%) had a history consistent with food allergy. These findings were not replicated in the renal transplant group. CONCLUSIONS: Young children with severe liver dysfunction appear to have a high prevalence of food sensitisation. Hepatic mechanisms may therefore be important for establishing immune tolerance to dietary antigens in humans.

Emollients, education and quality of life: the RCPCH care pathway for children with eczema.

OBJECTIVES: The Royal College of Paediatrics and Child Health (RCPCH) Science and Research Department was commissioned by the Department of Health to develop national care pathways for children with allergies. The eczema pathway focuses on defining the competences to improve the equity of care received by children with eczema. METHOD: The eczema pathway was developed by a multidisciplinary working group and was based on a comprehensive review of evidence. The pathway was reviewed by a broad group of stakeholders including paediatricians, allergists, dermatologists, specialist nurses, dietician, patients' representatives and approved by the Allergy Care Pathways Project Board and the RCPCH Clinical Standards Committee. It was also reviewed by a wide range of stakeholders. RESULTS: The results are presented in three sections: the evidence review, mapping and the core knowledge document. The various entry points to the ideal pathway of care are defined from self-care through to follow-up. There is considerable emphasis on good skin care and when allergy problems should be dealt with. The pathway algorithm and associated competences can be downloaded from http://www.rcpch.ac.uk/allergy/eczema. CONCLUSIONS: Effective eczema management is holistic and encompasses an assessment of severity and impact on quality of life, treatment of the inflamed epidermal skin barrier, recognition and treatment of infection and assessment and management of environmental and allergy triggers. Patient and family education which seeks to maximise understanding and concordance with treatment is also important in all children with eczema.

Bifidobacterium pseudocatenulatum is associated with atopic eczema: a nested case-control study investigating the fecal microbiota of infants.

BACKGROUND: Exposure to specific bacterial bowel commensals may increase/reduce the risk of atopic diseases. OBJECTIVE: To compare fecal bacterial communities of young infants with/without eczema. METHODS: Nested case-control study. Infants age 3 to 6 months with eczema (cases, n = 37) and without (controls, n = 24) were matched for sex, age, feeding (breast/bottle/mixed/solids), ethnicity. Information was collected on maternal/infant antibiotic exposure, feeding, gastrointestinal symptoms, family history of allergy. Eczema severity scoring was used (Severity Scoring of Atopic Dermatitis index). Samples were taken for determination of allergen-specific serum IgE (cases) and urinary/fecal eosinophilic protein X. Gastrointestinal permeability was measured. The compositions of fecal bacterial communities were analyzed (culture-independent, nucleic acid-based analyses). RESULTS: There was no difference in overall profiles of fecal bacterial communities between cases and controls. Family history of allergy increased likelihood of bifidobacteria detection (history, 86%; no history, 56%; P = .047); breast-fed infants were more likely to harbor Bifidobacterium bifidum (odds ratio, 5.19; 95% CI, 1.47-18.36; P = .01). Bifidobacterium pseudocatenulatum was detected more commonly in feces of non-breast-fed children (odds ratio, 5.6; 95% CI, 1.3-24.3; P = .02) and children with eczema (eczema, 26%; no eczema, 4%; P = .04). There were no significant associations between clinical measurements and detection of B pseudocatenulatum. CONCLUSION: Presence of B pseudocatenulatum in feces was associated with eczema and with exclusive formula-feeding; B bifidum was associated with breast-feeding.

Urinary eosinophilic protein X, atopy, and symptoms suggestive of allergic disease at 3 years of age.

BACKGROUND: Urinary eosinophilic protein X (U-EPX) measurement is easy to perform in children. However, its use for prediction, diagnosis, and monitoring of asthma and atopy is unclear. OBJECTIVE: We sought to investigate the relationship between U-EPX and clinical phenotypes suggestive of allergic diseases. METHODS: U-EPX measurement (RIA), respiratory questionnaires, and skin testing were completed at age 3 years in 903 children followed prospectively from birth. Specific airway resistance was measured in 503 currently asymptomatic children by using whole-body plethysmography during tidal breathing. RESULTS: Nonatopic children with wheezing or eczema had slightly increased U-EPX levels compared with nonatopic asymptomatic children. U-EPX levels (geometric mean EPX/creatinine ratio) were as follows: nonatopic asymptomatic children (n = 313), 61.3 microg/mmol (95% CI, 56.4-66.6 microg/mmol); nonatopic children with wheezing (n = 148), 71.2 microg/mmol (95% CI, 63.2-80.1 microg/mmol); nonatopic children with eczema (n = 90), 65.7 microg/mmol (95% CI, 56.7-76.2 microg/mmol); and nonatopic children with wheezing and eczema (n= 86), 79.7 microg/mmol (95% CI, 67.4-94.3 microg/mmol). Children who had persistent atopy early in life had significantly higher U-EPX levels at age 3 years (nonatopic at 1 and 3 years [n = 263], 63.4 microg/mmol [95% CI, 58.4-69.0 microg/mmol]; atopic at 1 but not 3 years [n = 24], 65.1 microg/mmol [95% CI, 43.8-96.7 microg/mmol]; nonatopic at 1 year and atopic at 3 years [n = 62], 90.0 microg/mmol [95% CI, 74.6-108.4 microg/mmol]; atopic at 1 and 3 years [n = 35], 111.5 microg/mmol [95% CI, 89.2-139.3 microg/mmol]; P <.002). Atopy alone and with wheezing, eczema, or both was associated with significantly increased U-EPX levels (P <.0001). Wheezing appeared to be associated with higher U-EPX levels compared with eczema in both atopic and nonatopic children. The highest U-EPX level was found in atopic children with a history of wheezing and eczema (P <.0001). There was no relationship between U-EPX level and lung function. CONCLUSION: U-EPX level reflects the presence of atopy and associated symptoms and might be useful for monitoring the progression of allergic disease.

Primary and secondary prevention of allergic airway disease.

The incidence of atopic conditions is continuing to rise. The number of primary prevention cohorts is increasing and results are becoming available. There is a lack of true secondary prevention trials, however. This article reviews the results currently available from primary and secondary prevention studies.
