Optimizing usability and signal capture: a proactive risk assessment for the implementation of a wireless vital sign monitoring system.

Wearable vital sign monitors are a promising step towards optimal patient surveillance, providing continuous data to allow for early detection and treatment of patient deterioration. However, as wearable monitors become more widely adopted in healthcare, there is a corresponding need to carefully design the implementation of these tools to promote their integration into clinical workflows and defend against potential misuse and patient harm. Prior to the roll-out of these monitors, our multidisciplinary team of clinicians, clinical engineers, information technologists and research investigators conducted a modified Healthcare Failure Mode and Effect Analysis (HFMEA), a proactive evaluation of potential problems which could be encountered in the use of a wireless vital signs monitoring system.

DNMT1 is regulated by ATP-citrate lyase and maintains methylation patterns during adipocyte differentiation.

During adipocyte differentiation, significant epigenomic changes occur in association with the implementation of the adipogenic program. We have previously shown that histone acetylation increases during differentiation in a manner dependent on acetyl coenzyme A (acetyl-CoA) production by the enzyme ATP-citrate lyase (ACL). Whether ACL regulates nuclear targets in addition to histones during differentiation is not clear.
