Combining theory and usability testing to inform optimization and implementation of an online primary care depression management tool.

Background: The 'Ottawa Depression Algorithm' is an evidence-based online tool developed to support primary care professionals care for adults with depression. Uptake of such tools require provider behaviour change. Identifying issues which may impact use of an innovation in routine practice (i.

Sodium zirconium cyclosilicate treatment and rates of emergency interventions for hyperkalaemia: a propensity-score weighted case-control study.

Background: Sodium zirconium cyclosilicate (SZC) reduces serum potassium in patients with chronic hyperkalaemia in clinical trials, but its role in the emergency treatment of hyperkalaemia is unproven. We hypothesized that SZC use for emergent hyperkalaemia would be associated with a reduction in rates of emergency interventions for hyperkalaemia.

Methods: This was a single-centre, propensity score-weighted case-control study of patients admitted with hyperkalaemia to a specialist renal centre.

FoxA1/2-dependent epigenomic reprogramming drives lineage switching in lung adenocarcinoma.

The ability of cancer cells to undergo identity changes (i.e., lineage plasticity) plays a key role in tumor progression and response to therapy.

Synthesis of a Near-Infrared Fluorescent Probe for Imaging Catecholamines via a Tandem Nucleophilic Aromatic Substitution.

A near-infrared (NIR) fluorescent probe NS667 was developed using a novel synthetic strategy by integrating an electron-rich 1,2,3,4-tetrahydroquinoxaline (THQ) into the scaffold from NS510, which binds to catecholamines with high affinity. The fluorophore core was constructed with a tandem nucleophilic aromatic substitution. Upon binding to catecholamines, the fluorescence of this probe shifted, with the emission in the NIR region.
