The sphingosine-1-phosphate-5 (S1P) receptor is one of the five membrane G protein-coupled receptors that are activated by the lysophospholipid, sphingosine-1-phosphate, resulting in regulation of many cellular processes. S1P receptors are located on oligodendrocytes and are proposed to influence oligodendrocyte physiology. Understanding S1P modulation during processes such as remyelination could have potential applications for demyelinating CNS disorders such as multiple sclerosis (MS).

Selective S1P radiotracers could enable in vivo positron emission tomography (PET) imaging of oligodendrocytes activity. Here we report the synthesis, radiolabelling and first preclinical evaluation of the pharmacokinetics and binding properties of a lead 6-arylaminobenzamide derivative, 6-(mesitylamino)-2-methoxy-3-methylbenzamide (also named as TEFM180), as a potential core scaffold for development of novel S1P PET radiotracers.

Utilizing data from the ongoing EXpanding Technology-Enabled, Nurse-Delivered Chronic Disease Care trial, this cross-sectional, correlational study explored the association between digital health literacy, health literacy, and patient outcomes, specifically blood pressure and hemoglobin A1c levels in 76 patients managing comorbid type 2 diabetes and hypertension. Results indicate patients had moderate digital health literacy, which was not significantly correlated with health literacy (r = 0.

In this project, we aimed to improve the understanding of RRT protocols through the development and implementation of the RRT Huddle Checklist. This quality improvement project took place from 2019 to 2022.

Aim: To develop evidence-based, psychologically informed interventions designed to improve PCC staff well-being that can be feasibility tested on a large scale.
