Research team diversity impacts scientific output in allergy and immunology programs.

Background: This study examined the relationship between the disciplinary diversity of research teams and research output (RO) in allergy and immunology programs funded by the National Institutes of Health (NIH) in the United States, Medical Research Council (MRC) in the United Kingdom, and Japan Society for the Promotion of Science (JSPS).

Methods: Using a dataset containing 1243, 3645, and 1468 articles funded by the NIH, MRC, and JSPS, respectively, we analyzed the correlation between disciplinary diversity and RO in allergy and immunology programs that received grants from 2017 to 2021. Diversity was measured using All Science Journal Classification codes counts, Shannon-Wiener index, and newly developed Omnidisciplinary index (o-index).

[STATE-OF-THE-ART OF GLOBAL START-UP INVESTMENT FOR ALLERGY AND IMMUNOLOGY 2022].

Background: In 2022, the "New Capitalism Grand Design and Implementation Plan" was adopted in Japan, emphasizing the promotion and environmental development of startups. Given this context, an investigation into the startup and investment landscape in the allergy sector, both domestically and internationally, becomes imperative.

Methods: We analyzed 156 allergy-related startups from Japan, the US, and Europe from 2010 to 2021.

[JAPANESE TRANSLATION AND LINGUISTIC VALIDATION OF THE RECAP OF ATOPIC ECZEMA (RECAP)].

Background: The Recap of atopic eczema (RECAP), a new core outcome of the atopic dermatitis trial, was translated into Japanese and linguistically validated.

Methods: Translation into Japanese was accomplished according to the ISPOR (International Society for Pharmacoeconomics and Outcome Research) guidelines and the basic guidelines for scale translation. The translation process included two forward translations, reconciliation with native English speakers, third-party back translation, cognitive debriefing, review and harmonization by the original authors.

Effect of Maternal Egg Intake During the Early Neonatal Period and Risk of Infant Egg Allergy at 12 Months Among Breastfeeding Mothers: A Randomized Clinical Trial.

Importance: Egg introduction in infants at age 4 to 6 months is associated with a lower risk of immunoglobulin E-mediated egg allergy (EA). However, whether their risk of EA at age 12 months is affected by maternal intake of eggs at birth is unknown.

Objective: To determine the effect of maternal egg intake during the early neonatal period (0-5 days) on the development of EA in breastfed infants at age 12 months.

Clinical risk factors at 3 months of age for the development of bronchial asthma at 36 months of age.

Background: We examined the associations between factors evident at the routine 3-month well-child visit (WCV) and the risk of developing 36-month parent-reported physician-diagnosed bronchial asthma (BA).

Methods: This longitudinal study was conducted in Nagoya City, Japan, and included 40,242 children who qualified for the 3-month WCVs in the city between April 1, 2016 and March 31, 2018. In total, 22,052 (54.

Executive summary: Japanese pediatric guideline for the treatment and management of asthma (JPGL) 2020.

This article covers the salient and updated themes of the Japanese Pediatric Guidelines for the Treatment and Management of Asthma (JPGL) 2020 published by the Japanese Society of Pediatric Allergy and Clinical Immunology. In the 2020 guidelines, five new clinical questions (CQs) have been added to address the 12 CQs regarding the treatment of childhood asthma. "Infant and preschool asthma" is diagnosed when young children (<6 years of age) have three or more episodes of clear expiratory wheezing, which continue for more than 24 h, and symptom improvement can be observed after beta-2 agonist inhalation.

Executive summary: Japanese guidelines for atopic dermatitis (ADGL) 2021.

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.

Prevalence of infantile wheezing and eczema in a metropolitan city in Japan: A complete census survey.

Infantile wheezing and eczema are associated with the subsequent onset of asthma and other atopic diseases. However, there are no large population-based surveys on infantile allergic symptoms in Japan. The objective of the study was to determine the prevalence of wheezing and asthma in infants in Nagoya, Japan.

Evaluation of adrenaline auto-injector prescription profiles: A population-based, retrospective cohort study within the National Insurance Claims Database of Japan.

Background: Adrenaline is the first-line medication for managing anaphylaxis. A better understanding of prescription trends for adrenaline auto-injectors (AAIs) is important to improving patient care as well as information on health education interventions and medical guidelines. However, it has been difficult to gather comprehensive data in a sustainable manner.

Asteatosis is a synonym of xerosis found in a wide range of diseases that induce dry skin through impaired functions of either water retention of the stratum corneum or skin covering with acid mantle. Patients with asteatosis may be accompanied by pruritus.

Is oral food challenge useful to avoid complete elimination in Japanese patients diagnosed with or suspected of having IgE-dependent hen's egg allergy? A systematic review.

Background: IgE-mediated egg allergy is a common food allergy worldwide. Patients with egg allergy are known to easily achieve tolerance compared to other allergens such as nuts. Oral food challenge (OFC) is often performed on patients diagnosed with or suspected of having IgE-mediated food allergy, but whether hen's egg OFC is useful in IgE-dependent egg allergy patients to avoid complete elimination remains unknown.
