Holdout-Based Empirical Assessment of Mixed-Type Synthetic Data.

AI-based data synthesis has seen rapid progress over the last several years and is increasingly recognized for its promise to enable privacy-respecting high-fidelity data sharing. This is reflected by the growing availability of both commercial and open-sourced software solutions for synthesizing private data. However, despite these recent advances, adequately evaluating the quality of generated synthetic datasets is still an open challenge.

Myocarditis Following Immunization With mRNA COVID-19 Vaccines in Members of the US Military.

Importance: Myocarditis has been reported with COVID-19 but is not clearly recognized as a possible adverse event following COVID-19 vaccination.

Objective: To describe myocarditis presenting after COVID-19 vaccination within the Military Health System.

Design, Setting, And Participants: This retrospective case series studied patients within the US Military Health System who experienced myocarditis after COVID-19 vaccination between January and April 2021.

Incomplete digestion of codfish represents a risk factor for anaphylaxis in patients with allergy.

Background: Fish represents one of the most important allergenic foods causing severe allergic reactions. Nevertheless, it has been shown that gastric digestion significantly reduces its allergenic capacity.

Objective: In this study, we assessed the absorption kinetics of fish proteins and investigated the clinical reactivity of patients with fish allergy to codfish digested at physiological or elevated gastric pH.

The effects of gastric digestion on codfish allergenicity.

Background: In a recent murine study, we showed that impaired gastric digestion supports the induction of fish allergy by protecting the digestion-sensitive major allergen parvalbumin and thus enhancing its sensitizing properties.

Objective: The aim of the present study was to investigate whether impairment of peptic degradation might also play a role in the effector phase of codfish allergy.

Methods: The resistance of cod proteins to digestion by simulated gastric fluid was assessed in vitro .

High prevalence of autoimmune urticaria in children with chronic urticaria.

Background: The etiology of chronic urticaria (CU) in childhood often remains unrecognized. Recently, in adults it has been shown that approximately 40% of patients with CU have autoimmune urticaria (AU); however, no data are available in children.

Objective: To determine the prevalence and possible risk factors for AU in children with CU.

Immunochemical and biological quantification of peanut extract.

Biological standardization of allergen extracts is one of the steps in the characterization of an extract. The gold standard for determination of biological potency is the skin prick test, but histamine release (HR) has been used as a convenient ex vivo method for analyzing a large number of samples. We describe the use of rabbit basophils as a tool in biological standardization.
