Journal: American journal of transplantation : official journal of the American Society of Transplantation and the American Society of Transplant Surgeons PubMed Link: https://pubmed.ncbi.nlm.nih.gov/41519473 Summary: The S. T. A. R. initiative’s working group has held three consensus meetings and published reports that have influenced clinical care in organ transplantation. The 2025 group identified and addressed five key evolving areas in transplantation: donor-derived cell-free D. N. A. tests, innate immunity in allograft rejection, immunogenicity and antigenicity, and H. L. A. antibody quantification. This demonstrates the group’s ongoing work in translating laboratory data into clinical practice and guiding future research priorities. Article 2: Phenotypic stratification and prognostic value of cardiac magnetic resonance in non-dilated left ventricular cardiomyopathy. Journal: Heart (British Cardiac Society) PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40819904 Summary: This study identified three distinct cardiac magnetic resonance-based phenotypes in 515 patients with non-dilated left ventricular cardiomyopathy. These phenotypes include late gadolinium enhancement positive with preserved left ventricular ejection fraction, late gadolinium enhancement negative with dilated left atrium or right ventricle and preserved left ventricular ejection fraction, and late gadolinium enhancement negative with isolated systolic dysfunction with preserved left ventricular ejection fraction. The classification of these phenotypes provides a new framework for risk stratification in this patient population. Article 3: Predicting the risk of motor vehicle crash in the first year after cardioverter-defibrillator implantation. Journal: Heart (British Cardiac Society) PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40555466 Summary: This study utilized 22 years of population-based administrative data to identify licensed drivers who received a first implantable cardioverter-defibrillator between 1998 and 2018. It developed a method using baseline health and driving data, along with logistic regression, to estimate the risk of motor vehicle crash in the first year post-implantation. This approach provides clinicians with a tool to personalize medical driving restrictions following implantable cardioverter-defibrillator implantation. Article 4: Early predictors of aortic valve surgery in patients with significant bicuspid aortic regurgitation without initial surgical indication. Journal: Heart (British Cardiac Society) PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40541293 Summary: This study identified a cohort of 335 patients with moderate or severe bicuspid aortic regurgitation who did not initially meet guideline-based criteria for aortic valve surgery. These patients were drawn from a single-center registry of 1927 individuals with bicuspid aortic valve, excluding those with severe aortic stenosis, endocarditis, or other major valvular diseases. The study establishes the critical need for identifying early predictors of disease progression within this specific high-risk subgroup to aid in optimal risk stratification and surgical timing. Article 5: Insomnia symptom trajectories and incident cardiovascular disease in older adults: a longitudinal cohort study. Journal: Heart (British Cardiac Society) PubMed Link: https://pubmed.ncbi.nlm.nih.gov/40425274 Summary: This longitudinal cohort study of 12000 participants aged 50 years or older investigated the associations between insomnia symptoms, their long-term ...
