The prevalence of infections amongst intensive care unit (ICU) patients is inevitably high, and the ICU is considered the epicenter for the spread of multidrug-resistant bacteria. Multiple studies have focused on the microbial diversity largely inhabiting ICUs that continues to flourish despite treatment with various antibiotics, investigating the factors that influence the spread of these pathogens, with the aim of implementing sufficient monitoring and infection control methods. Despite joint efforts from healthcare providers and policymakers, ICUs remain a hub for healthcare-associated infections.

The emergence of biobank-level datasets offers new opportunities to discover novel biomarkers and develop predictive algorithms for human disease. Here, we present an ensemble machine-learning framework (machine learning with phenotype associations, MILTON) utilizing a range of biomarkers to predict 3,213 diseases in the UK Biobank. Leveraging the UK Biobank's longitudinal health record data, MILTON predicts incident disease cases undiagnosed at time of recruitment, largely outperforming available polygenic risk scores.

Article Synopsis
  • Telomeres are protective caps on chromosomes, and their length is related to aging and diseases, prompting a study on telomere length in over 462,000 UK Biobank participants.
  • Researchers created a new metric for measuring telomere length that improved understanding of its genetic control and identified 64 genetic variants and 30 genes linked to telomere length.
  • Notably, many of these genes are involved in clonal hematopoiesis, which is linked to certain cancers, indicating a complex relationship between rare genetic variants and telomere length.

Article Synopsis
  • Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis, and the study investigates the role of soluble CD13 (sCD13) and its signaling through the bradykinin receptor B1 (B1R) in SSc pathogenesis.
  • Researchers found elevated levels of CD13, B1R, and MMP14 in skin from SSc patients, which contributed to fibrosis through signaling pathways activated by TGF-β and sCD13.
  • The study concludes that targeting the sCD13-B1R axis could represent a novel and effective therapeutic strategy for treating skin fibrosis in SSc.
