Buloxibutid reglerar överdriven inflammation vid virala luftvägsinfektioner utan att försämra virusbekämpningen. Forskare vid University of Southampton och Vicore Pharma AB kartlade hur substansen påverkar typ II alveolocyter genom att aktivera angiotensin II typ 2-receptorn. I cellförsök blockerade buloxibutid effektivt proinflammatoriska gensvar när cellerna exponerades för polyjnosinsk:polycytidylsyra, en virusimulator. Antivirala genuttryck förblev intakta. Detta mekanistiska mönster öppnar vägen för kliniska studier av buloxibutid vid viruspneumoni där cytokinöverproduktion driver allvarlig sjuklighet. För leverantörer av respiratorisk terapi och investerare i antivirala läkemedel utgör detta en kandidat för ett betydligt mindre överfyllt utvecklingskorridor än immunsuppressiva bredspektrumläkemedel. Regulatorisk väg för luftvägsindikation bör klargöras före IND-ansökan.

Titreringsguidad protaminreversering efter hjärt-lungmaskin under kranskärlskirurgi kräver ingen skärpning för att förhindra blödningar postoperativt. Svenska och norska kirurger vid Linköping universitet och Oslo universitetsjukhus undersökte 40 patienter och fann att återstående heparinaktivitet var vanlig efter låg-dos protamintitration — 60 procent hade detekterbara nivåer vid ankomst till intensivvård. Tre timmar senare steg andelen till 98 procent, men denna återuppträdande aktivitet korrelerade inte med operationsblödning. Protamin-heparin-kvoten (0,54 mg/100 U) påverkade initiala koagulationsmarkörer (aPTT och TT) men inte den senare heparinökningen. Resultaten tyder på att automatiserad titreringsstyrd dosering säkert balanserar antikoagulation utan att öka blödningsrisk, vilket kan göra dyrare reverseringsprotokoll överflödiga och reducera postoperativa transfusionsbehov vid hjärtkirurgi.

A major study of 4,500 heart disease patients reveals a growing population whose blood pressure drops below target despite medication—contradicting medical guidelines and raising questions about optimal care. The finding exposes a critical gap: European health authorities disagree on whether this is dangerous, leaving doctors and insurers uncertain about treatment adjustments.EN

An international panel of 56 intensive care specialists has reached consensus on clinical criteria to identify septic shock that doesn't respond to standard treatment.
