Aging

24
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

Types of Biopharmaceutical Studies: Controlled and Non-Controlled Approaches

106
Biopharmaceutical studies constitute a vital field aiming to enhance drug delivery methods and refine therapeutic approaches, drawing upon diverse interdisciplinary knowledge. In research methodologies, the choice between controlled and non-controlled studies significantly influences the study's reliability and accuracy.
Non-controlled studies, commonly employed for initial exploration, lack a control group, rendering them susceptible to biases and external influences. In contrast,...

Area of Science:

  • Geriatric Medicine
  • Health Informatics
  • Machine Learning in Healthcare

Background:

  • Managing geriatric risks (delirium, frailty, falls, etc.) is complex due to reliance on manual, time-intensive assessments.
  • Machine learning (ML) offers automated risk prediction using electronic health records (EHR), but often lacks geriatric-specific data.

Purpose of the Study:

  • To evaluate if geriatric-specific features improve EHR-based ML models for predicting geriatric risks.
  • To assess the performance enhancement of a one-shot Federated Learning (FL) approach in these models.

Main Methods:

  • Developed and compared three model types using linked EHR and acute geriatric data from three hospital providers.
  • Model types included: baseline EHR-only, EHR with geriatric features, and a FL ensemble.

Main Results:

  • Models incorporating geriatric-specific features demonstrated significantly improved performance.
  • A one-shot FL approach yielded only marginal, non-significant performance gains.

Conclusions:

  • Geriatric-specific features are indispensable for accurately modeling the acute geriatric population.
  • Enhanced predictive accuracy is achievable by integrating specialized geriatric data into ML models.
