Getting your DUCs in a row - standardising the representation of Digital Use Conditions.

Improving patient care and advancing scientific discovery requires responsible sharing of research data, healthcare records, biosamples, and biomedical resources that must also respect applicable use conditions. Defining a standard to structure and manage these use conditions is a complex and challenging task. This is exemplified by a near unlimited range of asset types, a high variability of applicable conditions, and differing applications at the individual or collective level.

Blood donor genotyping for prediction of blood group antigens: Results from 5 years' experience (2017-2022).

Background And Objectives: For 5 years, routine genotyping has been performed for selected blood groups of blood donors in the Copenhagen Capital Region, Denmark. The result is summarized in the following.

Materials And Methods: Genotyping was carried out by an external service provider using the competitive allele specific PCR (KASP) technology.

Reduced susceptibility to COVID-19 associated with ABO blood group and pre-existing anti-A and anti-B antibodies.

Background: Susceptibility to severe acute respiratory syndrome coronavirus 2 shows individual variability in un-vaccinated and previously un-exposed individuals. We investigated the impact of ABO blood group, titers of anti-A and anti-B, other blood group antigens, and the extracellular deposition of ABH antigens as controlled by secretor fucosyltransferase 2 (FUT2) status.

Study Design And Methods: We studied incidents in three different hospitals between April to September 2020, where un-diagnosed coronavirus disease 2019 (COVID-19) patients were cared for by health care workers without use of personal protection and with close contact while delivering therapy.

Secretor status of blood group O mothers is associated with development of ABO haemolytic disease in the newborn.

Background And Objectives: Identification of antibody characteristics and genetics underlying the development of maternal anti-A/B linked to inducing haemolytic disease of the foetus and newborn could contribute to the development of screening methods predicting pregnancies at risk with high diagnostic accuracy.

Materials And Methods: We examined 73 samples from mothers to 37 newborns with haemolysis (cases) and 36 without (controls). The secretor status was determined by genotyping a single nucleotide polymorphism in FUT2, rs601338 (c.

Droplet digital PCR-based testing for donor-derived cell-free DNA in transplanted patients as noninvasive marker of allograft health: Methodological aspects.

In solid organ transplantation, donor-derived cell-free DNA (dd-cfDNA) is a promising universal noninvasive biomarker for allograft health, where high levels of dd-cfDNA indicate organ damage. Using Droplet Digital PCR (ddPCR), we aimed to develop an assay setup for monitoring organ health. We aimed to identify the least distinguishable percentage-point increase in the fraction of minute amounts of cfDNA in a large cfDNA background by using assays targeting single nucleotide polymorphisms (SNPs).
