Our data establish premature senescence of myofibroblasts as an essential antifibrotic mechanism and potential therapeutic target in myocardial fibrosis.
Background: Negative feedback regulation of insulin signaling involves ubiquitin-dependent degradation of insulin receptor substrate 1 (IRS1). Results: Cullin-RING E3 ubiquitin ligase 7 (CRL7) mediates the ubiquitination of IRS1 in hyperphosphorylated form. Conclusion: Multisite IRS1 phosphorylation triggers interactions with CRL7 for ubiquitin modification. Significance: Insulin signaling is self-restrained when its downstream effector kinases are hyperactivated to trigger the negative feedback inhibition.
OBJECTIVE
To determine a just and consistent practice for creating nursing assignments.
BACKGROUND
Traditional methods of assigning patients to nurses may lead to unbalanced nursing workload. This article describes the ongoing, hospital-wide effort to evaluate and implement a nursing assignment tool based on electronic health record (EHR) functionality and auto-calculated nursing workload scores.
METHODS
EHR records of individual patient workload scores from all hospital units were collected from August 2017 to June 2018. A nurse-specific total workload score was summed for each staff. Then, each hospital unit's mean nurse workload score and standard deviation, along with the unit's nurse-to-patient ratio, were used to calculate levels of high, medium, and low nursing workload measurement (NWM).
RESULTS
Mean patient-specific workload scores varied greatly across hospital units. Unit-specific nurse-to-patient ratios were factored into NWM scores to create ranges for assignments that were relatively consistent across the institution.
CONCLUSION
The use of objective, electronically generated nursing workload scores, combined with traditional nurse-to-patient ratios, provides accurate real-time nurse staffing needs that can inform best practice in staffing. The confirmation of individual patient workload scores and an appreciation for the complexity of EHR vendor rules are necessary for successful implementation. Automation ensures patient safety, staff satisfaction, and optimal resource allocation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
