Outcomes of Del Nido and hyperkalemic blood cardioplegia in adult cardiac surgery with prolonged aortic cross-clamp times★.

Background: The utility and uptake of Del Nido cardioplegia in adult cardiac surgery is rapidly increasing. Cases with prolonged aortic cross-clamp times necessitate multi-dosing however an understanding of safe ischaemic times and definitive guidelines in this domain are lacking. Therefore, this study aimed to assess the safety and efficacy of our DNC strategy by comparing post-operative troponin profiles and clinical outcomes between Del Nido and hyperkalaemic cardioplegia for cases with aortic cross-clamp times of greater than 90 min.

A structure-based mechanism for initiation of AP-3 coated vesicle formation.

Adaptor protein complex-3 (AP-3) mediates cargo sorting from endosomes to lysosomes and lysosome-related organelles. Recently, it was shown that AP-3 adopts a constitutively open conformation compared to the related AP-1 and AP-2 coat complexes, which are inactive until undergoing large conformational changes upon membrane recruitment. How AP-3 is regulated is therefore an open question.

Causes, Solutions and Health Inequalities: Comparing Perspectives of Professional Stakeholders and Community Participants Experiencing Low Income and Poor Health in London.

Background: Engaging with the public can influence policy decisions, particularly towards more radical policy change. While established research exists exploring public perceptions on causes of health inequalities, much less exists on how to tackle health inequalities in the UK. Despite an emphasis on 'lived experience', currently no study has focused on how individuals with very poor health conceive of both causes of, and solutions to, health inequalities.

Bleeding disorder of unknown cause: an illustrated review on current practice, knowledge gaps, and future perspectives.

In more than half of the individuals with a clinically relevant bleeding tendency who are referred to hemostasis experts, no biological etiology can be found after extensive laboratory testing. These persons are diagnosed with an unexplained bleeding tendency or "bleeding disorder of unknown cause" (BDUC). The mucocutaneous bleeding phenotype of individuals with BDUC is generally comparable to that of individuals with inherited bleeding disorders such as von Willebrand disease or platelet function disorders.

Immunization but not natural infection of horses results in antibody activity against the S protein of Streptococcus equi subsp equi.

Objective: Evaluate the immunogenicity of a vaccine targeting the S protein (Ssee) of Streptococcus equi subsp equi and determine antibody activity against Ssee in horses with strangles.

Methods: The study was designed as a prospective experiment using 20 university-owned Quarter Horses and a cross-sectional serosurvey of 78 privately owned horses with strangles. Horses were immunized IM with 0 (n = 4), 200 (n = 8), or 400 (n = 8) μg of recombinant Ssee at weeks 0, 4, and 12.
