Article Synopsis
  • Frailty is linked to increased cardiovascular disease (CVD) risk and mortality among US veterans, highlighting the importance of identifying frailty for better health outcomes.
  • In a study of nearly 190,688 veterans aged 50 and older, frailty was assessed using three different scoring systems, revealing a significant correlation between frailty and higher mortality rates from all causes and CVD.
  • The results suggest that regardless of the method used to measure frailty, it consistently indicates a greater risk for negative health events, indicating a need for more research specifically focusing on younger veterans under 60.

Background: Aging-associated left ventricular dysfunction promotes cardiopulmonary fibrogenic remodeling, Group 2 pulmonary hypertension (PH), and right ventricular failure. At the time of diagnosis, cardiac function has declined, and cardiopulmonary fibrosis has often developed. Here, we sought to develop a molecular positron emission tomography (PET)-magnetic resonance imaging (MRI) protocol to detect both cardiopulmonary fibrosis and fibrotic disease activity in a left ventricular dysfunction model.

Article Synopsis
  • Accurate quantification of sodium intake via self-reported surveys has been problematic, prompting researchers to use machine-learning (ML) algorithms to better predict urinary sodium excretion based on questionnaire data.
  • The study involved 3,454 participants from major health studies and found ML predictions of sodium excretion were more reliable than traditional food frequency questionnaires, showing stronger correlations and better calibration.
  • However, while ML improved predictions overall, it was still heavily influenced by body size and did not significantly reduce measurement errors related to disease outcomes.

  • Activating mutations in the PTH/PTHrP receptor lead to Jansen's metaphyseal chondrodysplasia (JMC), characterized by growth plate issues, short stature, and high calcium levels not dependent on PTH.
  • Transgenic mouse models previously created for JMC did not accurately represent the disease, prompting the development of "humanized" mice that express the human mutation through the appropriate mouse promoter in all target tissues.
  • These new JMC mice exhibited significant growth plate abnormalities, reduced serum PTH and P1NP levels, and may serve as a better model for studying JMC and exploring treatment possibilities.
