Urinary metabolite model to predict the dying process in lung cancer patients.

Background: Accurately recognizing that a person may be dying is central to improving their experience of care at the end-of-life. However, predicting dying is frequently inaccurate and often occurs only hours or a few days before death.

Methods: We performed urinary metabolomics analysis on patients with lung cancer to create a metabolite model to predict dying over the last 30 days of life.

An optimised faecal microRNA sequencing pipeline reveals fibrosis in Trichuris muris infection.

The intestine is a site of diverse functions including digestion, nutrient absorption, immune surveillance, and microbial symbiosis. Intestinal microRNAs (miRNAs) are detectable in faeces and regulate barrier integrity, host-microbe interactions and the immune response, potentially offering valuable non-invasive tools to study intestinal health. However, current experimental methods are suboptimal and heterogeneity in study design limits the utility of faecal miRNA data.

Detection and quantification of ergothioneine in human serum using surface enhanced Raman scattering (SERS).

Ergothioneine (ERG) is a natural sulfur-containing amino acid found in many organisms, including humans. It accumulates at high concentrations in red blood cells and is distributed to various organs, including the brain. ERG has numerous health benefits and antioxidant capabilities, and it has been linked to various human physiological processes, such as anti-inflammatory, neuroprotective, and anti-aging effects.

Regulatory T cell therapy is associated with distinct immune regulatory lymphocytic infiltrates in kidney transplants.

Background: Adoptive transfer of autologous regulatory T cells (Tregs) is a promising therapeutic strategy aimed at enabling immunosuppression minimization following kidney transplantation. In our phase 1 clinical trial of Treg therapy in living donor renal transplantation, the ONE Study (ClinicalTrials.gov: NCT02129881), we observed focal lymphocytic infiltrates in protocol kidney transplant biopsies that are not regularly seen in biopsies of patients receiving standard immunosuppression.
