Health Care Workers' Attitudes Toward and Knowledge of the Clinical Application of Classic Psychedelics for People with Serious Illness: A Systematic Review.

Recent research indicates that psychedelic-assisted therapy (PAT) may be a safe and effective treatment for several psychiatric disorders, including those experienced by people with serious physical illness. Understanding health care workers' (HCWs') attitudes and knowledge about the clinical application of psychedelics for patients with serious illness is important in progressing research and identifying factors to consider in potential future implementation of PAT. The aim of this systematic review was to synthesize quantitative, qualitative, and mixed methods studies that explored HCWs' attitudes and knowledge about the role of psychedelics in treating psychological distress in patients with serious illness.

Clonal hematopoiesis of indeterminate potential (CHIP) and its association with treatment outcomes and adverse events in patients with solid tumours.

Clonal hematopoiesis of indeterminate potential (CHIP) is the clonal expansion of hematopoietic stem cells from somatic mutations. It is a common incidental finding in cell-free DNA (cfDNA). We investigated the incidence of CHIP in cfDNA from patients with solid tumours and explored its association with treatment outcomes and adverse events.

Plasma arginine as a predictive biomarker for outcomes with immune checkpoint inhibition in metastatic colorectal cancer: a correlative analysis of the CCTG CO.26 trial.

Background: Nutritional stress is a mechanism that allows tumor cells to evade the immune system. Arginine (ARG), an amino acid involved in immunomodulation, aids in regulating T-lymphocyte cell activity and the antitumor response. ARG deficiency in the tumor microenvironment can impair T-cell response while ARG supplementation may promote antitumor immune activity.
