Background: The use of artificial intelligence (AI) in scientific writing is rapidly increasing, raising concerns about authorship identification, content quality, and writing efficiency. Objectives: This study investigates the real-world impact of ChatGPT, a large language model, on those aspects in a simulated publication scenario. Methods: Forty-eight individuals representing 3 medical expertise levels (medical students, residents, and experts in allergy or dermatology) evaluated 3 blinded versions of an atopic dermatitis case report: one each human written (HUM), AI generated (AI), and combined written (COM). The survey assessed authorship, ranked their preference, and graded 13 quality criteria for each text. Time taken to generate each manuscript was also recorded. Results: Authorship identification accuracy mirrored the odds at 33%. Expert participants (50.9%) demonstrated significantly higher accuracy compared to residents (27.7%) and students (19.6%, P < .001). Participants favored AI-assisted versions (AI and COM) over HUM (P < .001), with COM receiving the highest quality scores. COM and AI achieved 83.8% and 84.3% reduction in writing time, respectively, compared to HUM, while showing 13.9% (P < .001) and 11.1% improvement in quality (P < .001), respectively. However, experts assigned the lowest score for the references of the AI manuscript, potentially hindering its publication. Conclusion: AI can deceptively mimic human writing, particularly for less experienced readers. Although AI-assisted writing is appealing and offers significant time savings, human oversight remains crucial to ensure accuracy, ethical considerations, and optimal quality. These findings underscore the need for transparency in AI use and highlight the potential of human-AI collaboration in the future of scientific writing.

An outbreak of coronavirus disease 2019 (COVID-19) caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) started in Wuhan, Hubei Province, China and quickly spread around the world. Current evidence is contradictory on the association of asthma with COVID-19 and associated severe outcomes. Type 2 inflammation may reduce the risk for severe COVID-19. Whether asthma diagnosis may be a risk factor for severe COVID-19, especially for those with severe disease or non-allergic phenotypes, deserves further attention and clarification. In addition, COVID-19 does not appear to provoke asthma exacerbations, and asthma therapeutics should be continued for patients with exposure to COVID-19. Changes in the intensity of pollinization, an earlier start and extension of the pollinating season, and the increase in production and allergenicity of pollen are known direct effects that air pollution has on physical, chemical, and biological properties of the pollen grains. They are influenced and triggered by meteorological variables that could partially explain the effect on COVID-19. SARS-CoV-2 is capable of persisting in the environment and can be transported by bioaerosols which can further influence its transmission rate and seasonality. The COVID-19 pandemic has changed the behavior of adults and children globally. A general trend during the pandemic has been human isolation indoors due to school lockdowns and loss of job or implementation of virtual work at home. A consequence of this behavior change would presumably be changes in indoor allergen exposures and reduction of inhaled outdoor allergens. Therefore, lockdowns during the pandemic might have improved some specific allergies, while worsening others, depending on the housing conditions.

Background: Newborn screening (NBS) for the early detection of inborn errors of immunity (IEI) has been implemented in a few countries. The objective of this study was to verify the situation and define obstacles to the implementation of NBS worldwide. Methods: A questionnaire was developed by the Inborn Errors of Immunity Committee of the World Allergy Organization (WAO) with 17 questions regarding NBS for IEI in the physician's workplace, NBS test type, problems hindering NBS implementation, reimbursement for IEI therapy, presence of a national IEI registry, referral centers, molecular diagnosis, hematopoietic stem cell transplantation centers, gene therapy, and immunoglobulin replacement therapy. The survey was sent by email once a week to doctors and others associated with WAO and the main immunology societies worldwide as a Google Form™ to be completed during September and October 2021. Results: Two hundred twenty-nine questionnaires were completed, of which 216 (94.3%) were completed by physicians. One hundred seventy-six (76.8%) physicians were both allergists and immunologists. The agreement between allergists/immunologists and non-allergists/non-immunologists for the question “Is there NBS for IEI in the country you work in?” was good (κ = 0,64: 95% CI 0.55–0.69). Ninety-eight (42.8%) participants were from Latin America, 35 (15.3%) from North America, 29 (12.6%) from Europe, 18 (7.9%) from Africa, 44 (19.2%) from Asia, and 5 (2.2%) from Oceania. More than half the participants (n = 124, 54.2%) regularly treated patients with IEI, followed by occasional treatment (n = 77, 33.6%), or never (n = 28, 12.2%). Of the respondents, 14.8% reported that their countries performed NBS for IEI, whereas 42.2% reported their countries did not. T-cell receptor excision circles was the most widely used technique in some countries, with 75 (59.9%) for the diagnosis of NBS for IEI, followed by combined use with kappa deleting-recombination excision circles. Only 13 participants (10.3%) underwent neonatal exon screening in their respective countries. Financial and technical issues were among the major obstacles to the implementation of NBS for IEI. Conclusions: This pilot study showed that few countries have implemented NBS for IEI, despite the presence of immunology referral centers and the availability of hematopoietic stem cell transplantation and intravenous immunoglobulin replacement therapy. The findings highlight the difficulties, mainly financial and technical, hindering wide application of NBS. Sharing experiences, technologies, and resources at the international level can help overcome these difficulties.
