ALK, NUT, and TRK are rare molecular aberrations that are pathognomonic for specific rare tumors. In low frequencies, however, they are found in a wide range of other tumor entities. This study aimed to investigate the frequency, association with clinicopathological characteristics, and prognosis of the immunohistochemical expressions of ALK, NUT, and TRK in 477 adenocarcinomas of the stomach and gastroesophageal junction. Seven cases (1.5%) showed an expression of TRK. In NGS, no fusion was confirmed. No case with ALK or NUT expression was detected. , and expression does not seem to play an important role in gastric carcinomas.

Effects of Food Processing on Allergenicity.

Purpose Of Review: There is an increasing awareness among clinicians that industrial and household food processing methods can increase or decrease the allergenicity of foods. Modification to allergen properties through processing can enable dietary liberations. Reduced allergenicity may also allow for lower risk immunotherapy approaches.

Background: Unnecessary dietary eliminations may impair quality of life, affect children's growth, and negatively impact healthcare costs. Previous studies reported that around 11 % to 28 % of children continue a food-avoidance diet despite a negative oral food challenge (OFC).
Objectives: This study aimed to evaluate the actual consumption at home of the tested food after a negative OFC and the reasons reported by families in the case of persistent avoidance.

IgE antibodies raised against innocuous environmental antigens cause allergic diseases like allergic rhinitis, food allergy, and allergic asthma. While some allergies are often outgrown, others (peanut, shellfish, tree nut) are lifelong in the majority of individuals. Lifelong allergies are the result of persistent production of allergen-specific IgE.

Flying with nut and other food allergies: unravelling fact from fiction.
Arch Dis Child
December 2024
Aviation Medical Consultancy Limited, Burgess Hill, UK.
There is a common perception that peanut/tree nut particles can be transmitted through aircraft ventilation systems and pose a significant risk to passengers with food allergies. In fact, food-induced allergic reactions are around 10-100 times less common during flights than 'on the ground', perhaps because of the multiple precautions food-allergic passengers take when flying. We review the evidence for strategies to help prevent accidental allergic reactions while travelling on commercial flights (review registered at PROSPERO, ref CRD42022384341).
