Abstract Background The production of IgE molecules specific to the carbohydrate galactose‐α‐1,3‐galactose (alpha‐gal) is known induce delayed anaphylaxis against mammalian meat. Tick bites constitute primary sensitization source, as ticks transfer alpha‐gal in their saliva a host during bite. reported prevalence alpha‐gal‐specific (alpha‐gal‐ sIgE ) positivity varies between different populations from diverse geographic regions. Objective To investigate alpha‐gal‐ population forest service...

Background and Purpose— In patients receiving direct oral anticoagulants (DOACs), emergency treatment like thrombolysis for acute ischemic stroke is complicated by insufficient availability of DOAC-specific coagulation tests. Conflicting recommendations have been published concerning the use global assays ruling out relevant DOAC-induced anticoagulation. Methods— Four hundred eighty-one samples from 96 DOAC-treated were tested using prothrombin time (PT), activated partial thromboplastin...
