The endothelial-specific regulatory mutation, Mvwf1, is a common mouse founder allele

Mvwf1 is a cis-regulatory mutation previously identified in the RIIIS/J mouse strain that causes a unique tissue-specific switch in the expression of an N-acetylgalactosaminyltransferase, B4GALNT2, from intestinal epithelium to vascular endothelium. Vascular B4galnt2 expression results in aberrant glycosylation of von Willebrand Factor (VWF) and accelerated VWF clearance from plasma. We now report that 13 inbred mouse strains share the Mvwf1 tissue-specific switch and low VWF phenotype, including five wild-derived strains. Genomic sequencing identified a highly conserved 97-kb Mvwf1 haplotype block shared by these strains that encompasses a 30-kb region of high nucleotide sequence divergence from C57BL6/J flanking B4galnt2 exon 1. The analysis of a series of bacterial artificial chromosome (BAC) transgenes containing B4galnt2 derived from the RIIIS/J or C57BL6/J inbred mouse strains demonstrates that the corresponding sequences are sufficient to confer the vessel (RIIIS/J) or intestine (C57BL6/J)-specific expression patterns. Taken together, our data suggest that the region responsible for the Mvwf1 regulatory switch lies within an approximately 30-kb genomic interval upstream of the B4galnt2 gene. The observation that Mvwf1 is present in multiple wild-derived strains suggests that this locus may be retained in wild mouse populations due to positive selection. Similar selective pressures could contribute to the high prevalence of von Willebrand disease in humans

Evaluation of patient satisfaction and experience towards pharmacist-administered vaccination services in Western Australia

Background: Pharmacist-administered vaccination services have been available in various countries for several years. In 2014, Western Australian (WA) legislation was introduced to allow pharmacist immunisers to administer the influenza vaccine to consumers 18 years and older. Objective: To determine consumer satisfaction with pharmacist-administered influenza vaccination services in WA and identify factors associated with opinions to extend the service to include other vaccines. Setting: Thirteen WA community pharmacies. Method: In 2015, 133 pharmacies in WA offered pharmacist-administered influenza vaccinations. Of the 133 pharmacies, a purposive sample of 10% (13) were invited to participate in this 2016 study. Following vaccination, consumers were given a questionnaire and asked to evaluate the service and if they would support expansion of the service to include other vaccinations. Main outcome measure Consumer satisfaction with aspects of the service using a 5-point Likert scale. Results: A total of 434 (66.8%) questionnaires were completed at the 13 pharmacies and returned. The majority of consumers (99.5%) were satisfied with the service overall, and 97.2% advised they would receive a vaccination from a community pharmacist in the future. Over 60% would like vaccinations to expand to other conditions. Women and those who would again have their influenza vaccine from the pharmacist were particularly supportive of this expansion. Conclusion: Consumer satisfaction with pharmacist-administered vaccinations was high. Consumers found the service convenient, comfortable and professional. The majority of respondents supported expansion of pharmacist-administered vaccination services to a wider range of vaccines
