Article Synopsis
  • Increased cardiorespiratory fitness is linked to a lower risk of cardiovascular disease (CVD), Alzheimer's disease (AD), and Parkinson's disease (PD), although the exact reasons for this relationship are not fully understood.
  • A study involving nearly 502,486 individuals from the UK Biobank found that even small increases in fitness were associated with significant reductions in the risks of these diseases over a median follow-up of 11 years.
  • The research supports the idea that maintaining fitness may play a crucial role in the early detection and prevention of age-related diseases, contributing to personalized and preventive healthcare strategies.

Type 2 diabetes (T2D) is often comorbid with cardiovascular diseases (CVDs). The direction of causation between T2D and CVD is difficult to determine; however, there may be a common underlying pathway attributable to shared genetic factors. We aimed to determine whether there is a shared genetic susceptibility to T2D and CVD.

Article Synopsis
  • The oral glucose tolerance test is not commonly used for diabetes screening due to its high cost and complexity, leading to misdiagnosis of patients with isolated post-challenge hyperglycemia (IPH).
  • A diagnostic system, the IPH Diagnosis System (IPHDS), was developed using data from over 54,000 participants, employing machine learning algorithms to identify individuals with IPH based on ten selected features.
  • The IPHDS demonstrated a strong performance with an AUC of 0.823 in external validation, showing better accuracy than existing models, and is available online for instant predictions, making it a practical tool for diabetes screening in the general population.

Introduction: Previous studies reported leucocyte telomere length (LTL) and frailty were associated with mortality, but it remains unclear whether frailty serves as a mediator in the relationship between leucocyte telomere length and mortality risk. This study aimed to evaluate how measuring LTL and frailty can support early monitoring and prevention of risk of mortality from the prospective of predictive, preventive, and personalized medicine (PPPM/3PM).

Methods: We included 440,551 participants from the UK Biobank between the baseline visit (2006-2010) and November 30, 2022.
