Methods: We analysed the records for 108 transfusions performed at a Central London Teaching Hospital. All the patients were asked whether they gave written or verbal consent prior to transfusion of packed red cells and whether they received a blood transfusion information leaflet. Results: Of the...
DNA methylation alterations occur at the beginning of tumor growth. A previous longitudinal study on 200,000 people showed that a DNA methylation-based blood test can detect five types of cancer at four years before conventional diagnosis45. In addition, a study led by University College London f...
Moreover, we originally aimed to test only people who were > 40 years but the Pop-Up generated a lot of interest and we examined younger people too; consequently, around one quarter of our participants were younger than 40 years. Our study design meant our results are limited to ...
Besides the threat of a consumer backlash, companies also increasingly worry about potential legal liabilities, perhaps from an investor lawsuit, should they violate human rights. In July, the London Metal Exchange said that starting in January it would require every company that sources more than a...
The cost of blood culture contamination often exceeds the cost of performing the test [76]. A retrospective case-control study evaluated 142 false positive blood cultures and found a significant increase in length of hospital stay as well as laboratory and pharmacy costs, they also calculated that...

Carlsenet al.demonstrated that the estimation of central blood pressure from peripheral tonometry does not work properly in patients with chronic kidney disease. We explore here the implications of this findings, first by considering the technical conditions for validating central BP monitors, then by ...

In addition, when this underlying physiological mechanism remains the same (e.g., different iterations of the cold-pressor test), these parameters are expected to demonstrate comparable behavior. However, if the input features have low correlation with the proxy hemodynamic parameter (e.g., caused...
The protocol was overseen by a supervisor who monitored the adequacy of reference and test device BP measurements, the agreement between the two observers, who were unaware of the magnitude or direction of their disagreement, and any other issue arising during the validation procedure. The superviso...
