Background: Patients with heart failure (HF) can experience a poor quality-of-life (QOL), recurring hospitalizations, and progressive disease symptoms. Patient-reported outcome measures (PROMs) integrate patients' voices into clinical care, by assessing patient symptoms, function, and QOL. In 2022, PROMs were incorporated into the electronic health record system (Epic) at a large academic hospital in Toronto, Ontario, Canada.

Glycosylphosphatidylinositols (GPIs) are highly conserved anchors for eukaryotic cell surface proteins. The apicomplexan parasite, , is a widespread intracellular parasite of warm-blooded animals whose plasma membrane is covered with GPI-anchored proteins, and free GPIs called GIPLs. While the glycan portion is conserved, species differ in sidechains added to the triple mannose core.

Article Synopsis
  • Apparent resistant hypertension (aTRH) is a serious health concern where standard treatments fail, prompting the use of aldosterone-direct-renin-ratio (ADRR) to identify potential issues like aldosterone-producing adenoma (APA) and primary aldosteronism (PA).
  • The study, conducted on Afro-Colombian individuals with resistant hypertension, categorized the patients into phenotypes based on their plasma renin and aldosterone levels, aiming to understand how these classifications could influence treatment decisions, though optimal cut-off points are still unclear.
  • Results showed that 62.5% of participants adhered to at least three hypertension medications, with significant data collected on their sodium intake and the prevalence of

Foundation models are transforming artificial intelligence (AI) in healthcare by providing modular components adaptable for various downstream tasks, making AI development more scalable and cost-effective. Foundation models for structured electronic health records (EHR), trained on coded medical records from millions of patients, demonstrated benefits including increased performance with fewer training labels, and improved robustness to distribution shifts. However, questions remain on the feasibility of sharing these models across hospitals and their performance in local tasks.

Carbohydrate reserves play a vital role in plant survival during periods of negative carbon balance. Under a carbon-limited scenario, we expect a trade-offs between carbon allocation to growth, reserves, and defense. A resulting hypothesis is that carbon allocation to reserves exhibits a coordinated variation with functional traits associated with the 'fast-slow' plant economics spectrum.
