Frailty as a trigger for goals-of-care discussions in rapid response calls: A single-centre retrospective cohort study.

Background: Timely goals-of-care (GOC) discussions are essential for end-of-life planning, particularly during acute hospital admissions, where ambiguity often persists. Frailty, prevalent in the ageing population and linked to adverse outcomes, underscores the need to align treatment strategies with quality of life. Recognising frailty as a trigger for GOC discussions during rapid response calls (RRCs) is critical for efficient resource management and improving patient outcomes.

Transcutaneous auricular vagus nerve stimulation augments postprandial inhibition of ghrelin.

Vagus nerve stimulation (VNS) facilitates weight loss in animals and patients treated with VNS for depression or epilepsy. Likewise, chronic transcutaneous auricular VNS (taVNS) reduces weight gain and improves glucose tolerance in Zucker diabetic fatty rats. If these metabolic effects of taVNS observed in rats translate to humans is unknown.

Oral Misoprostol for Induction of Labour in Term PROM: A Systematic Review.

Objective: To assess the efficacy of oral misoprostol for induction of labour (IOL) in the context of term pre-labour rupture of membranes (TPROM), and to assess pregnancy outcomes following the administration of oral misoprostol.

Data Sources: A systematic literature search was performed using Ovid Medline, Embase, PubMed, and the Cochrane Database of Systematic Reviews.

Study Selection: Eligible studies were quasi-experimental trials or randomized controlled trials involving the use of oral misoprostol in singleton cephalic term pregnancies with confirmed rupture of membranes and no spontaneous labour at the time of membranes rupture, in mothers with no contraindications to vaginal delivery.

The thioredoxin redox potential and redox charge are surrogate measures for flux in the thioredoxin system.

The thioredoxin system plays a central role in intracellular redox regulation and its dysregulation is associated with a number of pathologies. However, the connectivity within this system poses a significant challenge for quantification and consequently several disparate measures have been used to characterize the system. For in vitro studies, the thioredoxin system flux has been measured by NADPH oxidation while the thioredoxin redox state has been used to estimate the activity of the system in vivo.

The thioredoxin system and not the Michaelis-Menten equation should be fitted to substrate saturation datasets from the thioredoxin insulin assay.

Introduction: The thioredoxin system, consisting of thioredoxin reductase, thioredoxin and NADPH, is present in most living organisms and reduces a large array of target protein disulfides.

Objective: The insulin reduction assay is commonly used to characterise thioredoxin activity in vitro, but it is not clear whether substrate saturation datasets from this assay should be fitted and modeled with the Michaelis-Menten equation (thioredoxin enzyme model), or fitted to the thioredoxin system with insulin reduction described by mass-action kinetics (redox couple model).

Methods: We utilized computational modeling and in vitro assays to determine which of these approaches yield consistent and accurate kinetic parameter sets for insulin reduction.
