Background: Anaphylaxis is a systemic allergic reaction that is potentially life-threatening. Occupational anaphylaxis is an anaphylaxis that occurs in an occupational context. In this position paper, we propose diagnostic criteria for occupational anaphylaxis and provide an overview of the current state of knowledge in terms of prevalence, triggers, prevention, and management.

Article Synopsis
  • Timely diagnosis of leptospirosis is crucial for preventing severe health outcomes in both humans and animals, and current diagnostic methods have limitations that necessitate new approaches.
  • This study explores a novel diagnostic tool using a recombinant lipoprotein (rErpY-LIC11966) in a latex agglutination test (LAT), which was developed and tested for its effectiveness in diagnosing animal leptospirosis.
  • The rErpY-LAT demonstrated high diagnostic performance, with 90.6% sensitivity, 89.1% specificity, and 90% overall accuracy, making it a promising field-applicable option for early serodiagnosis of the disease.

Article Synopsis
  • Rubber gloves often have rubber accelerators that can cause allergic reactions, but their specific content is not well understood.
  • A study tested 51 gloves from various brands, finding that 90% of disposable gloves contained sensitizing rubber accelerators, particularly zinc dibutyldithiocarbamate (ZDBC) and zinc diethyldithiocarbamate (ZDEC).
  • The research highlights the need for better labeling of rubber gloves, as even those claimed to be free of accelerators were found to have them, necessitating more transparency from manufacturers.

Article Synopsis
  • The study aimed to analyze the sensitization to latex and food allergens in atopic dermatitis patients using the ALEX2 Allergy Xplorer test, comparing the results with personal histories of allergies.
  • The study included 100 patients, examining specific IgE responses to latex and collecting detailed allergy histories.
  • The findings revealed 17% sensitization to latex, primarily linked to specific protein components, with some patients showing allergic reactions to latex or related fruit syndromes, underscoring the connections between molecular components and clinical reactions.

Here, Yb-based Eosin Y lakes (EOS-Yb) have been encapsulated in organic nanoparticles (NPs) by microemulsion radical polymerization of methacrylate-based copolymers. These photoactive EOS-Yb NPs emit in the visible and near infrared (NIR) upon excitation at 530 nm and can also display NIR-to-visible upconversion emission upon excitation at 980 nm.
