Abstract
BACKGROUND Idiopathic nephrotic syndrome (NS) presents as a hypercoagulable state, of which thromboembolism (TE) is a well-known life-threatening complication. Although TE is more likely to occur in venous vessels than arterial vessels, arterial TE is important because it may cause after-effects, including tissue necrosis and cerebral infarction (CI); therefore, prompt diagnosis and appropriate treatment are required. We report a pediatric NS case with multiple CIs. CASE PRESENTATION A 14-year-7-month-old Japanese girl was diagnosed with frequent relapsing NS, accompanied by headache and disturbance of consciousness during the second relapse. Brain magnetic resonance imaging (MRI) and four-dimensional computed tomography revealed multiple CIs, vasogenic edema, and cerebral venous sinus thrombosis (CVST). The patient had no underlying thrombophilia other than hypercoagulability due to NS and prednisolone (PSL), and no cardiac arrhythmia; however, a right-to-left shunt through the patent foramen ovale (PFO) was observed with the Valsalva maneuver by echocardiography. Therefore, we assumed that a potential cause of multiple CIs might be an embolic stroke, caused by thrombosis formed from a hypercoagulable state due to NS and PSL treatment and reached through PFO. Antiplatelet and anticoagulant therapies were administered for TE. She was treated with PSL and mycophenolate mofetil (MMF) for NS. Rituximab (RTX) was administered to prevent NS relapse after complete remission (CR). She underwent transcatheter PFO closure at age 14 years and 9 months because we considered that the right-to-left shunt through the PFO would be one of the risks for recurrent cerebral embolism when NS relapses. One year after the onset of CIs, an MRI indicated that the CVST had resolved, leaving no neurological sequelae due to CI; therefore, anticoagulant therapy was discontinued. And then she has been in CR for NS with only MMF therapy. CONCLUSIONS CI is a serious complication in patients with NS. The pathogenesis of multiple CIs is various, including right-to-left shunt through PFO, in addition to the hypercoagulability due to NS. It is important to investigate and manage underlying risks such as PFO, besides preventing the relapses of NS by aggressive treatments using MMF and RTX, in patients with NS.

Abstract
PURPOSE Factors associated with positive mental health in children with chronic diseases remain unclear. Supporting the development of positive mental health in children with chronic diseases can enhance their mental health throughout childhood and adulthood. This study aimed to identify the factors associated with positive mental health among Japanese young adults with a history of chronic pediatric diseases. DESIGN AND METHODS Participants aged 18-25 years, with a history of chronic pediatric diseases, were recruited from a population of students at a university. Semi-structured interviews were conducted. The data were analyzed using thematic analysis. After the initial coding of each transcript, the researchers discussed and identified a set of main themes, categories, and subcategories. RESULTS Ten participants aged 19-22 years were interviewed. Their chronic diseases were diverse and included childhood cancers and allergic diseases. Seven themes (proactive coping, positive coping, negative coping, eudaimonia, hedonia, independence, and awareness) emerged from 21 categories and 70 subcategories identified. A thematic map was applied to two domains (protective factors and well-being factors) and to three inter-related constructs (individual, family, and community/society). CONCLUSIONS The findings indicated that within the well-being factors, meaning in life was prominent, and within the protective factors, stress coping was found to facilitate positive mental health among individuals with a history of chronic pediatric diseases. PRACTICE IMPLICATIONS In children with chronic diseases, support for finding appropriate coping strategies that enhance their optimism and symbiotic relationships in the community/society are important, including valuing little things in their lives, such as play and learning.

Abstract
BACKGROUND Itch is the most troublesome symptom of atopic dermatitis, and it is important to assess it appropriately for optimal treatment. We discussed issues regarding itch and the most appropriate methods of assessment at the Atopic Itch Consensus Meeting (AICOM), attended by physicians and researchers with expertise in itch treatment and research. METHODS The AICOM participants prepared a draft consensus statement that addressed the most appropriate itch assessment methods for age groups <2 years, 2-6 years, 7-14 years, and ≥15 years. Consensus was defined as agreement by ≥80% of the participants. RESULTS Votes were cast by 20 participants (8 dermatologists, 7 pediatricians, and 5 researchers), and a consensus on the best current methods of itch assessment was reached with 95% agreement. For infants and preschool children, because subjective evaluation is difficult, a checklist for itch assessment was developed for caregivers. CONCLUSION For itch assessment, we recommend subjective evaluation by the patient using a rating scale. For infants and preschoolers, evaluation should be done by the caregiver using a checklist, combined with objective evaluation (of skin lesions, for example) by a physician. We anticipate that more objective itch assessment indices will be established in the future.

Abstract
Background There is currently little research into factors predicting the results of an initial diagnostic oral food challenge (OFC) test for food protein-induced enterocolitis syndrome (FPIES). Objective The present study aimed to identify predictors of the diagnosis of hen's egg yolk-induced FPIES (HEY-FPIES). Methods The present monocentric study was performed at Tokyo Metropolitan Children's Medical Center and included patients who underwent hen's egg yolk OFC (HEY-OFC) between March 2018 and March 2023 to assess for HEY-FPIES. The baseline characteristics of the groups and HEY-OFC positivity or negativity were then compared. Univariate analysis was conducted by using the Mann-Whitney U test or Fisher exact test. Receiver operator characteristic analysis was used to create probability curves. Results In total, 35 patients were analyzed; of these, 17 were HEY-OFC-positive. No significant difference was observed between the HEY-OFC-positive and HEY-OFC-negative groups in terms of background factors except for the HEY-LST value, which was significantly higher in the HEY-LST group (P = .027). Receiver operator characteristic analysis demonstrated that the area under the curve for HEY-OFC positivity using the HEY-LST value was 0.719 (95% CI = 0.541-0.897). The statistically optimal cutoff value for the HEY-LST was 610%, which had a clinical sensitivity and specificity of 64.7% and 83.3%, respectively. Conclusions The present study demonstrated that the HEY-LST may be a useful predictor of the result of an initial OFC for HEY-FPIES.

Abstract
Skin surface contamination by alpha-emitters is in itself not hazardous, but it would cause significant internal exposure in the case of injured skin as well as misjudgment in direct in vivo measurements (e.g. lung counting). The present study determined the source efficiency of alpha-emitters (241Am) applied to swine skin samples by analysing the observed alpha-particle energy spectra using advanced alpha-spectrometric simulation. Based on our results, the source efficiency was determined to be 0.365 (alpha-particle s-1 per Bq) on average (c.f. 0.5 in the case of no self-absorption in the source). The decrease in source efficiency would be attributed primarily to the radionuclide entering hair follicles or deep wrinkles. The degradation of the measured spectra from the skin samples indicates the penetration of some radionuclides into the upper layers of the stratum corneum. Although this study was limited to results obtained from swine skin samples, it suggests that irregularities in the skin surface may affect direct alpha measurements.

Abstract
Background Allergic diseases are some of the most common diseases worldwide. Genome-wide association studies (GWASs) have been conducted to elucidate the genetic factors of allergic diseases. However, no GWASs for allergen component sensitization have been performed. Objective We sought to detect genetic variants associated with differences in immune responsiveness against allergen components. Methods The participants of the present study were recruited from the Tokyo Children's Health, Illness, and Development study, and allergen component-specific IgE level at age 9 years was measured by means of allergen microarray immunoassays. We performed GWASs for allergen component sensitization against each allergen (single allergen component sensitization, number of allergen components analyzed, n = 31), as well as against allergen protein families (allergen protein group sensitization, number of protein groups analyzed, n = 16). Results We performed GWAS on 564 participants of the Tokyo Children's Health, Illness, and Development study and found associations between Amb a 1 sensitization and the immunoglobulin heavy-chain variable gene on chromosome 14 and between Phl p 1 sensitization and the HLA class II region on chromosome 6 (P < 5.0 × 10-8). A GWAS-significant association was also observed between the HLA class II region and profilin sensitization (P < 5.0 × 10-8). Conclusions Our data provide the first demonstration of genetic risk for allergen component sensitization and show that this genetic risk is related to immune response genes including immunoglobulin heavy-chain variable gene and HLA.

Abstract
There are no data about risk factor of admission and long-term (>1 year) prognosis of proactive therapy using topical corticosteroids (TCSs) in school children. This study aims to identify the prognosis of school children over 3 years treated with proactive therapy after hospitalization due to atopic dermatitis (AD). This retrospective cohort study used electronic medical record data of schoolchildren (aged 5-19 years) with a long-term admission program for AD at the National Center for Child Health and Development from January 2008 to December 2013. Long-term prognosis at 1 and 3 years after discharge were retrospectively identified from their medical records. The most common exacerbation factor was poor adherence (51.8%). At 1 and 3 years after hospitalization, 87.3% and 74.3%, respectively, of the children used TCSs on their trunk and limbs less than twice a week. Investigator's Global Assessment of AD scores were ≤1 for 81.0%and 75.7% at 1 and 3 years after discharge, respectively. AD was well-controlled during follow-up. Rehospitalization due to AD was observed in 11.8% children. Poor adherence was biggest risk factor for admission. Children with severe AD could achieve well-controlled AD with a long-term admission AD program and home-based proactive therapy using TCSs for 3 years after discharge. Maintaining good adherence for AD treatment is required to prevent exacerbation and improve future prognosis in school children. However, we need to engage for the children who required rehospitalization.

Abstract
This is an abridged edition of English version of the Clinical Practice Guidelines for the Management of Atopic Dermatitis 2021. Atopic dermatitis (AD) is a disease characterized by relapsing eczema with pruritus as a primary lesion. In Japan, from the perspective of evidence-based medicine, the current strategies for the treatment of AD consist of three primary measures: (i) use of topical corticosteroids, tacrolimus ointment, and delgocitinib ointment as the main treatment of the inflammation; (ii) topical application of emollients to treat the cutaneous barrier dysfunction; and (iii) avoidance of apparent exacerbating factors, psychological counseling, and advice about daily life. In the present revised guidelines, the description about three new drugs, namely, dupilumab, delgocitinib, and baricitinib, has been added. The guidelines present recommendations to review clinical research articles, evaluate the balance between the advantages and disadvantages of medical activities, and optimize medical activity-related patient outcomes with respect to several important points requiring decision-making in clinical practice.

Abstract
Background Mobile health apps can support the self-management of pediatric asthma. Previous studies on mobile apps for children aged >7 years with asthma are limited, and most reports on asthma apps do not consider interactions between the children and their caregivers. Therefore, we developed an asthma app for children aged 0-12 years and their caregivers based on the results of our previous study regarding user needs. Objective The aim of this study was to evaluate the feasibility of a developed mobile app for children with asthma and their caregivers and to modify and complete the app according to the feasibility results. Methods We recruited children diagnosed with persistent asthma by an allergy specialist at 2 children’s hospitals, 1 university hospital, 2 general hospitals, and 1 pediatric clinic. Thereafter, the app usage was assessed, and questionnaires were administered. This study used convergent mixed methods, including providing user feedback about the pediatric asthma app, completing questionnaire surveys regarding preferences, and obtaining quantitative data about app usage. Quantitative data were analyzed based on the ratings provided for the app features used by the participants, and the usage of the app features was analyzed using descriptive statistics. Qualitative data were analyzed via a descriptive qualitative research analysis and were used to identify codes from the content-characteristic words. Results In total, 30 pairs of children aged 2-12 years and their caregivers responded to the 3-month survey, and 20 pairs of children aged 4-12 years and their caregivers responded to the 6-month survey. In the 3- and 6-month surveys, “record” was the most commonly used feature by both caregivers and children. The average access logs per month among the 20 pairs ranged from 50 to 79 in the 6-month survey. The number of access logs decreased over time. In the qualitative results, app utilization difficulties were identified for 6 categories: record, preparing, alert settings, change settings, mobile phone owner, and display and motivation. Regarding app feasibility, 60% (12/20) of the caregivers strongly agreed or agreed for all evaluation items, while 63% (7/11) of the children strongly agreed or agreed for 6 items, excluding satisfaction. In the qualitative results, feasibility evaluation of the app was classified into 3 categories: high feasibility of the app, improvement points for the app, and personal factors preventing app utilization. Based on the results of the feasibility analysis, the final version of the app was modified and completed. Conclusions The app feasibility among children with asthma and their caregivers was generally good. Children aged 7-12 years used elements such as record, quiz, and manga. This app can support the continuous self-management of pediatric asthma. However, efforts must be taken to maintain and improve the app quality.

Abstract
OBJECTIVES To examine whether eating status and dietary variety were associated with functional disability during a 5-year follow-up analysis of older adults living in a Japanese metropolitan area. DESIGN A 5-year follow-up study. SETTING Ota City, Tokyo, Japan. PARTICIPANTS A total of 10,308 community-dwelling non-disabled adults aged 65-84 years. MEASUREMENTS Eating status was assessed using a self-reported questionnaire. Dietary variety was assessed using the dietary variety score (DVS). Based on the responses, participants were classified according to eating alone or together and DVS categories (low: 0-3; high: 4-10). Functional disability incidence was prospectively identified using the long-term care insurance system's nationally unified database. Multilevel survival analyses calculated the adjusted hazard ratio (HR) and 95% confidence interval (CI) for incident functional disability. RESULTS During a 5-year follow-up, 1,991 (19.3%) individuals had functional disabilities. Eating status or DVS were not independently associated with incident functional disability. However, interaction terms between eating status and DVS were associated with functional disability; HR (95% CI) for eating together and low DVS was 1.00 (0.90-1.11), eating alone and high DVS was 0.95 (0.77-1.17), and eating alone and low DVS was 1.20 (1.02-1.42), compared to those with eating together and high DVS. CONCLUSION Older adults should avoid eating alone or increase dietary variety to prevent functional disability. This can be ensured by providing an environment of eating together or food provision services for eating a variety of foods in the community.

Abstract
INTRODUCTION Food-induced anaphylaxis among infants shows an increasing prevalence; however, the prescription of epinephrine auto-injectors (EAIs) for children weighing <15 kg is associated with issues of the needle length and the epinephrine dose. Several studies have shown age-related differences in food-induced anaphylaxis, although little is known about the weight-related differences in food-induced anaphylaxis. This study aimed to reveal the incidence, clinical characteristics, and management of food-induced anaphylaxis in children weighing <15 kg. METHODS This chart review included children who visited the pediatric emergency department (ED) of the National Center for Child Health and Development (Tokyo, Japan) from January 2014 to December 2016 and were diagnosed with food-induced anaphylaxis. The severity of anaphylaxis was evaluated using the Sampson Grading Scale. RESULTS Of 89,232 ED visits, 444 visits included patients with food-induced anaphylaxis, after excluding cases of food-induced anaphylaxis related to oral desensitization therapy. The incidence was 4.98 per 1,000 visits. More than half of the children (n = 247/444, 55.6%) weighed <15 kg. The proportion of grade 3 and higher severity anaphylactic symptoms was 74.5% (184/247) in children weighing <15 kg and 79.2% (156/197) in children weighing 15 kg or more. The recurrence rate of food-induced anaphylaxis was 22.3% (55/247) in children weighing <15 kg and 48.7% (96/197) in children weighing 15 kg or more. Among the children weighing <15 kg, the proportion of those with recurrent food-induced anaphylaxis was 4 times higher in children weighing 10-15 kg than in those weighing <10 kg (32.2% [47/146] vs. 7.9% [8/101]). The proportion of patients who were prescribed EAIs before each visit was 25.5% (14/55) in children weighing <15 kg with a history of food-induced anaphylaxis. CONCLUSION Food-induced anaphylaxis among children weighing <15 kg occurred as frequently and was as severe as that among children weighing 15 kg or more. However, the proportion of patients prescribed EAIs was very low in children weighing <15 kg with food-induced anaphylaxis. The potential need for EAIs is suggested among children weighing <15 kg, especially among children weighing 10 kg or more but <15 kg.

Abstract
Atopic dermatitis (AD) is the most common inflammatory skin disease in children. The serum level of thymus and activation-regulated chemokine (TARC) is a useful AD index to reflect disease severity; however, it requires blood collection from young children. In comparison, urine samples are easier to collect in a pediatric clinical setting. Here, we analyzed the lipids excreted in urine to identify a diagnostic biomarker for AD. We generated a murine dermatitis model by repeated topical application of 2,4-dinitrofluorobenzene (DNFB) or tape-stripping the dorsal skin. Lipid metabolites excreted in the urine were comprehensively analyzed using liquid chromatography-tandem mass spectrometry. To corroborate our findings, we also analyzed urine samples from patients with AD. DNFB application induced AD-like skin lesions, including epidermal thickening, infiltration of eosinophils and T cells, and an increase in Th2 cytokine levels. Assessment of lipids excreted in urine showed a dominance of prostaglandins (PGs), namely, a PGF2α metabolite (13,14-dihydro-15-keto-tetranor-PGF1α ), a PGE2 metabolite (13,14-dihydro-15-keto-tetranor-PGE2 ), and a PGD2 metabolite (13,14-dihydro-15-keto PGJ2 ). mRNA and protein expression of PGF2α , PGE2 , and PGD2 synthase was upregulated in DNFB-treated skin. The tape-stripping model also caused dermatitis but without Th2 inflammation; urine PGF2α and PGD2 metabolite levels remained unaffected. Finally, we confirmed that the urinary levels of the aforementioned PG metabolites, as well as PGI2 metabolite, 6,15-diketo-13,14-dihydro-PGF1α and arachidonic acid metabolite, 17-hydroxyeicosatetraenoic acid (17-HETE) increased in patients with AD. Our data highlights the unique urinary lipid profile in patients with AD, which may provide insight into novel urinary biomarkers for AD diagnosis.

Abstract
BACKGROUND: Progress towards TB elimination in the United States will require improved detection and treatment of latent TB infection among non-U.S.-born residents who remain at disproportionate risk of TB disease. To inform targeted testing efforts, we evaluated risk of TB disease among non-U.S.-born residents of Washington State, USA, by region of origin and time from U.S. entry.METHODS: We conducted a retrospective cohort study among non-U.S.-born residents diagnosed with TB disease in Washington State from 2005 to 2014, for which country-specific population estimates were also available. The risk of TB disease among non-U.S.-born residents was estimated by time since U.S. entry, World Bank region of origin, and WHO TB incidence category.RESULTS: Risk of TB disease for non-U.S.-born residents was highest within the first year after U.S. entry. Among persons from countries with high TB incidence who had resided in the United States for more than 20 years, risk for TB remained elevated.CONCLUSION: Elevated risk of developing TB disease among individuals not born in the United States persisted long after U.S. entry, particularly among persons originating from certain regions and from high-burden countries. These findings contribute to evidence supporting a refinement of existing screening guidelines.

Abstract
Summary Buckwheat (BW) is a major food allergen and one of the leading causes of food-induced anaphylaxis in Japan. The standard method of diagnosing food allergy is the oral food challenge (OFC). The BW-specific IgE (BW-sIgE) value is used to assess BW allergy but its utility is limited.The aim of the present study was to identify factors with predictive value for the diagnosis of BW allergy using the OFC.We evaluated 37 patients who were classified into the positive or negative group according to their OFC results. Ten patients (27.0%) showed objective or persistent, moderate, subjective symptoms during the OFC. The positive group had a significantly higher BW-sIgE/total IgE ratio than the negative group (p less than 0.001), but the total IgE (p = 0.139) and BW-sIgE (p = 0.130) did not differ significantly. Receiver operator characteristic (ROC) analysis showed that the BW-sIgE/total IgE ratio had a larger area under the curve (AUC, 0.885) than BW-sIgE (AUC, 0.667). The statistically optimal cut-off was 0.0058 for the BW-sIgE/total IgE ratio, which corresponded to a clinical sensitivity and specificity of 90.0% and 81.5%, respectively.BW-s IgE/total IgE ratio may be more useful predictor of BW OFC results than BW-s IgE.

Abstract
Allergic rhino-conjunctivitis with pollen allergy has been prevalent worldwide and Pollen-food allergy syndrome (PFAS) refers to individuals with pollen allergy who develop oral allergy syndrome (OAS) on consuming fruits and vegetables. The prevalence of PFAS varies by region and that in Japanese adolescents remains to be elucidated. In this cross-sectional study, we examined the epidemiological characteristics of PFAS in a general population of Japanese adolescents according to pollen allergy, OAS, and IgE component sensitization. Participants comprised adolescents, at age 13 years, from a prospective birth cohort study in Japan. We administered questionnaires to collect information from parents regarding pollen allergy, PFAS and OAS at each child’s age 13 years. ImmunoCAP ISAC was used to assess IgE component sensitization. Among 506 participants with a complete questionnaire and ISAC measurement results, 56.5% had a history of hay fever, 16.0% had a history of OAS, 51.0% had pollen allergy, and 11.7% had a history of PFAS; additionally, 72.7% were sensitized to one or more tree, grass, and/or weed allergens. The most common sensitization (95.7%) among adolescents with pollen allergy was to Japanese cedar (Cry j 1). The most common causal foods were kiwi and pineapple (both 39.0%). Knowledge levels about PFAS were poor among affected adolescents. We found a high prevalence of PFAS among adolescents in Japan. Although it affects approximately 1/10 adolescents in the general population, public awareness regarding PFAS is poor. Interventional strategies are needed to increase knowledge and to prevent PFAS in the general population.

Abstract
OBJECTIVE To examine the association between the severity of oral frailty (OF), which is one of the comprehensive oral functions evaluated, and dietary variety in community-dwelling older persons. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS A total of 769 community-dwelling older persons aged 65 and over. INTERVENTIONS We examined basic demographic information, functional status, cognitive status, depressive symptoms, medical history, and oral functions of the participants. MEASUREMENTS OF was defined by 1-2 and 3 or more of 6 items of oral function evaluation in the pre-oral frailty and oral frailty groups, respectively. Dietary variety was assessed using the dietary variety score (DVS). The participants were categorized into 3 groups for evaluation: those with a low score (0-2), medium score (3-5), and high score (≥6). Ordinal logistic regression analysis was performed to examine the association between OF and DVS. RESULTS The rate of OF in the participants was 21.6%, and its severity was significantly associated with DVS after adjusting for potential confounders (Pre-OF; adjusted odds ratio [OR] = 1.687, 95% confidence interval [CI] = 1.219-2.335, OF; adjusted OR = 2.857, 95% CI = 1.489-5.484). CONCLUSION The severity of OF was significantly associated with DVS in community-dwelling older persons. This suggests that DVS may be useful in understanding the effects of OF on the nutritional status. Further longitudinal studies are needed to elucidate the association between OF and DVS.

Abstract
Prostaglandin D2 (PGD2 ) plays an important role in atopic dermatitis (AD), and 11,15-dioxo-9α-hydroxy-2,3,4,5-tetranorprostan-1,20-dioicacid (PGDM) is a major metabolite of PGD2 . We investigated the relationship between urinary PGDM levels and severity of paediatric AD. In total, 31 patients with AD and 21 healthy controls (HCs) without AD were recruited, and urinary PGDM levels were measured. Of the 31 patients with AD, 14 were reassessed for urinary PGDM after topical steroid therapy. There was no difference in urinary PGDM levels between patients with AD and HCs. Although there was a significant positive correlation between the SCORing Atopic Dermatitis (SCORAD) index and the serum level of thymus and activation-regulated chemokine (TARC), the urinary PGDM levels did not correlate with either SCORAD or serum TARC. Moreover, both SCORAD and serum TARC were significantly improved by topical steroid therapy; however, urinary PGDM levels were not changed. In conclusion, the level of urinary PGD2 metabolites in children with AD is substantially the same as that in HCs even if the disease is severe.

Abstract
Background mHealth and uHealth apps are available for children with asthma and their caregivers. However, previous studies on mHealth apps for children older than 7 years old with asthma are limited, and most studies on asthma apps do not consider interactions involving communication between children and caregivers. Therefore, a prototype mHealth child asthma app was developed for children and their caregivers, with features of tailored feedback messages in continuing self-management and interactions between children and caregivers. Objective The aim of this study was to identify the beneficial features of a prototype mHealth app developed for children with asthma and their caregivers. Methods Children diagnosed with persistent asthma by allergy specialists at the National Center for Child Health and Development were recruited. The features of a prototype mHealth app for children with asthma and their caregivers were investigated using semistructured interviews after they tried the app. Data were analyzed using thematic analysis. Content-characteristic words were named and grouped together as categories to explore themes. Results We recruited 27 children with asthma aged 2 to 12 years and 26 their caregivers. Findings on the good aspects of the app for children older than 7 years old and caregivers suggested 4 themes (confirmation of asthma knowledge, child-caregiver interaction, design of the app, and child’s interest), and 6 categories were identified. Findings on the good aspects of app for children 7 to 12 years old and caregivers suggested 5 themes (new knowledge, manga as a Japanese-style comic, child’s interest, trigger of self-management, and design and operability), and 11 categories were identified. Findings on the beneficial features of app suggested 6 themes (asthma knowledge, elements for continuous, universal design, notification, monitoring, and functions), and 12 categories were identified. Conclusions Children with asthma and their caregivers perceived that the good aspects of the app were learning asthma knowledge with fun, including manga; interaction between child and caregiver; and easy-to-read design, such as colors. They wanted not only the asthma knowledge but also the universal design and enhanced elements, monitoring, and notification functions of the app.

Abstract
Background In Japan, swimming school attendance is promoted as a form of therapy or as a prophylactic measure against asthma in young children. However, the putative beneficial effects have not been sufficiently verified. Objective The aim of the present study was to clarify whether or not swimming school attendance at age 3 years affects the onset and/or improvement of wheeze and rhinitis at age 5 years. Methods This study was a single-center, prospective, general, longitudinal cohort study (T-CHILD Study). Between November 2003 and December 2005, 1776 pregnant women were enrolled, and their offspring were followed up until age 5 years. Swimming school attendance at age 3 years and the presence of wheeze and/or rhinitis in the previous one year were examined using the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. The relationship between swimming school attendance and wheeze and/or rhinitis was analyzed using multivariable logistic regression analysis. Results Data on the 1097 children were analyzed. At age 3 years, 126 (11.5%) children attended a swimming school, and at age 5 years, the prevalence of wheeze was 180 (16.4%) while that of rhinitis was 387 (35.3%). Swimming school attendance at age 3 showed no significant relationship with the development of either wheeze (aOR 0.83, 95% CI (0.43–1.60) or rhinitis (aOR 0.80, 95% CI (0.43–1.60) at age 5. Conclusions Swimming school attendance at age 3 years showed neither a preventive nor therapeutic effect on wheeze or rhinitis at age 5 years. There is thus no scientific evidence yet that swimming school attendance has a positive impact on the development of childhood wheeze or rhinitis.

Abstract
BACKGROUND Response patterns to allergen components among Japanese children have not been studied extensively. OBJECTIVE Our aim was to examine the differences in sensitization patterns at ages 5 years and 9 years to identify longitudinal changes in the degree and patterns of sensitization in a birth cohort of Japanese children. METHODS Our study enrolled 984 children at aged 5 years between 2008 and 2010, and 729 children aged 9 years between 2012 and 2014. Allergic diseases were assessed using the ISAAC and UK Working Party's Diagnostic Criteria. Serum-specific IgE titers to allergen components were measured by multiplex array ImmunoCAP ISAC when the children were aged 5 and 9 years. Principal component analysis (PCA) was performed to characterize IgE sensitization to allergen components. RESULTS The prevalence of allergic rhinitis increased considerably over time (10.6%-31.2%). Furthermore, the sensitization prevalence to allergen-specific IgE (sIgE) also increased from 57.8% at age 5 years to 74.8% at age 9 years. IgE sensitization prevalence to Der f 1 (mites) was 42.1% at age 5 years and 54.3% at age 9 years. Furthermore, children were highly sensitized to Cry j 1 (Japanese cedar) (32.8% at age 5 years and 57.8% at age 9 years). Principle component analysis showed that sensitization to PR-10 cross-reactive components was independent of sensitization to mite and that no children acquired sensitization to pollen before acquiring sensitization to mite. CONCLUSIONS The prevalence of allergic rhinitis and related allergen components increased from age 5 years to age 9 years in Japanese children.

Abstract
Eosinophilic esophagitis has been reported as a complication of oral immunotherapy (OIT), but there are only a few reports of eosinophilic gastroenteritis (EGE) occurring after OIT. EGE causes eosinophil infiltration into the gastrointestinal (GI) tract and is characterized by various digestive symptoms. We report the case of a 6-year-old boy with EGE. He was diagnosed as having immediate-type food allergies (egg, milk and wheat) by oral food challenges at 1 year of age. OIT for each food was carried out, and the amounts of the offending foods were able to be gradually increased without causing any immediate-type allergy symptoms. However, the total IgE and specific IgE values were remarkably increased at the age of 4 years and 4 months. He first developed oral mucosa symptoms and vomiting at 4 years and 10 months of age, and they gradually worsened. Stopping eggs and milk alleviated the symptoms. Nevertheless, he still occasionally vomited. He started Pica eating disorder (sand and sponge) due to anemia from 5 years and 10 months of age and developed eosinophilia without diarrhea or bloody stool. Upper and lower GI tract endoscopic examinations found no bleeding. The GI mucosa showed eosinophil infiltration of more than 40/high-power field in the stomach and duodenum, so he was diagnosed with EGE. No eosinophils were found in the esophageal mucosa. His GI symptoms and anemia improved on a multiple-food-elimination diet. Patients undergoing OIT should be closely followed up for a long time, and those with GI symptoms should be evaluated by GI endoscopy.

Abstract
Abstract
Introduction
Recent evidences have demonstrated that coagulation pathway is involved in cardiovascular remodeling induced by renin-angiotensin system (RAS), which finally leads to heart failure. Protease activated receptor-1 (PAR-1) is widely expressed in the vasculature and the heart, and plays important roles in pro-inflammatory process in the cardiovascular system. Recently, we demonstrated that the activity of factor Xa (FXa), which functions not only as a coagulation factor but as an agonist for PAR-1, was enhanced in renin-overexpressing hypertensive mice (Ren-Tg).
Purpose
The purpose of this study was to investigate whether inhibition of PAR-1 signaling has protective effects on the progression of heart failure induced by chronic RAS activation in Ren-Tg.
Methods and results
We treated 12–16 weeks-old male wild type mice (WT) and Ren-Tg with continuous subcutaneous infusion of PAR-1 antagonist SCH79797 (25mg/kg/day) or vehicle for 4 weeks. After treatment period, left ventricular (LV) wall thickness calculated as interventricular septum plus posterior wall thickness measured by echocardiography was greater in Ren-Tg than in WT (0.25±0.003 versus 0.18±0.002 mm), and SCH79797 attenuated the increase to 0.22±0.01 mm in Ren-Tg (both p<0.05, respectively). The ratio of heart weight to body weight was greater in Ren-Tg than in WT (6.1±0.4 versus 4.6±0.7 mg/g), and SCH79797 attenuated the increase to 5.2±0.1 mg/g (both p<0.05). The area of cardiac fibrosis evaluated by Masson-trichrome staining was greater in Ren-Tg than in WT (2.6±0.2 versus 1.4±0.3%), and SCH79797 attenuated it to 1.6±0.3% in Ren-Tg (both p<0.05). Cardiac mRNA expressions of tumor necrosis factor-α, transforming growth factor-β1, and β-myosin heavy chain were all greater in Ren-Tg than in WT, and SCH79797 attenuated the increases in Ren-Tg (all p<0.05).
Conclusions
Inhibition of PAR-1 signaling attenuates cardiac hypertrophy and fibrosis in Ren-Tg via inhibition of inflammatory cytokines production. These results support the involvement of PAR signaling in the development of heart failure induced by RAS, and may provide novel therapeutic insights for the treatment of hypertensive heart failure.

Abstract
OBJECTIVES This study evaluated associations of score-based and nutrient-derived dietary patterns with depressive symptoms in community-dwelling older Japanese. DESIGN Cross-sectional study. SETTING Community-based. PARTICIPANTS 982 community-dwelling adults aged 65 years or older. MEASUREMENTS Score-based pattern was assessed by using dietary variety score (DVS), which covers 10 food group items in Japanese meals. Nutrient-derived dietary patterns were identified by using reduced rank regression (RRR), with folate, vitamin C, magnesium, calcium, iron, and zinc intakes as response variables. Depressive symptoms were assessed with the Geriatric Depression Scale. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for these dietary patterns in multivariate logistic regression analyses with potential confounders. The lowest consumption category was used as the reference group. RESULTS The prevalence of depressive symptoms was 13.5%. Higher DVS was associated with fewer depressive symptoms (OR=0.52, 95% CI=0.27-1.03 for the highest vs the lowest DVS; P for trend=0.031). The first RRR dietary pattern score was characterized by high intakes of fish, soybean products, potatoes, most vegetables, mushrooms, seaweeds, fruits, and green tea and a low intake of rice and was inversely associated with the prevalence of depressive symptoms (OR=0.53, 95% CI=0.30-0.92; P for trend=0.030). CONCLUSION Greater dietary variety and a dietary pattern characterized by high intakes of fish, soybean products, potatoes, most vegetables, mushrooms, seaweeds, fruit, and green tea and a low intake of rice were consistently associated with lower prevalence of depressive symptoms in community-dwelling older Japanese. Therefore, both patterns identified the components of dietary habits essential to depression prevention.

Abstract
BACKGROUND Exploring patterns of childhood wheeze may help to clarify the etiology and prognosis of respiratory diseases. The purpose of this study was to classify phenotypes of wheezing in children up to 9 years of age in Japan and to evaluate the individual and environmental risk factors for these phenotypes. METHODS Wheeze was evaluated at approximately 1-year intervals based on the mothers' recollection of their child's wheezing or whistling in the chest during the preceding 12 months. The children were aged 1-9 years. In total, 1116 children who had at least five measures of wheezing at all nine time points were used for identifying trajectories. Trajectories were identified with group-based trajectory analysis. A multinomial logit model was built to evaluate the relationships between phenotypes and risk factors. RESULTS Five typical trajectories were identified. The probability of group membership was 43.7%, 32.2%, 6.2%, 8.6%, and 9.2% for the never/infrequent wheeze, transient early wheeze, school-age-onset wheeze, early-childhood-onset remitting wheeze, and persistent wheeze trajectories, respectively. Infant tobacco exposure increased the odds of membership in the transient early wheeze trajectory compared to the never/infrequent wheeze trajectory. CONCLUSIONS Using the group-based trajectory modeling approach, we identified five trajectories of childhood wheeze development in a Japanese population. The trajectories shown here are based on formal statistical modeling rather than on subjective classification, and an assessment of its precision suggested that the model has high assignment accuracy.
