Despite the widespread inclusion of statistics in medical school curricula as per the Liaison Committee on Medical Education requirements, the statistical competency among medical students and clinicians remains low. A 2007 study of 277 medical residents revealed only 41.1% scored correctly on a statistical knowledge survey, with minimal understanding of key concepts such as confidence intervals and adjusted odds ratios.

Although prediction models for heart transplantation outcomes have been developed previously, a comprehensive benchmarking of survival machine learning methods for mortality prognosis in the most contemporary era of heart transplants following the 2018 donor heart allocation policy change is warranted. This study assessed seven statistical and machine learning algorithms-Lasso, Ridge, Elastic Net, Cox Gradient Boost, Extreme Gradient Boost Linear, Extreme Gradient Boost Tree, and Random Survival Forests in a post-policy cohort of 7,160 adult heart-only transplant recipients in the Scientific Registry of Transplant Recipients (SRTR) database who received their first transplant on or after October 18, 2018. A cross-validation framework was designed in mlr.

Background: Coronary artery disease (CAD) is a complex, heterogeneous disease with distinct etiological mechanisms. These different etiologies may give rise to multiple subtypes of CAD that could benefit from alternative preventions and treatments. However, so far, there have been no systematic efforts to predict CAD subtypes using clinical and genetic factors.

Article Synopsis
  • Patients with type 2 diabetes mellitus (T2DM) show a higher risk of cognitive impairment, prompting a study on the effects of a specific LDL-C subfraction called L5 on their cognitive function.
  • The study involved 68 T2DM patients, examining their cognitive abilities and using a new analysis method, HHSA, to assess the impact of L5 on neural activity.
  • Results indicated that higher L5 levels are linked to increased risks of mild cognitive impairment (MCI) and Alzheimer’s disease, with a negative correlation between L5 and cognitive performance, particularly in MCI patients, suggesting L5 could serve as a useful biomarker for cognitive decline in T2DM.
