Younger age (OR 0.96, 95% CI 0.94 to 0.98, p<0.001), lack of access to an IBD nurse (OR 1.81, 95% CI 1.03 to 3.19, p=0.04) and lack of education on reducing infection risk (OR 1.99, 95% CI 1.13 to 3.50, p=0.017) were associated with significant stress, anxiety and/or depression. High prevalence of undiagnosed depression, anxiety and stress was identified among respondents. Improved access to IBD nurse support and greater attention to education are modifiable factors that may reduce depression, anxiety and/or stress among patients with IBD during the pandemic.

Using single-cell RNA sequencing analysis in a bilateral tumor model, we found that immunosuppressive myeloid cells with characteristics of fatty acid oxidative metabolism dominate the immune-cell landscape in ICB-resistant subjects. In addition, we uncovered a previously underappreciated role of a serine/threonine kinase, PIM1, in regulating lipid oxidative metabolism via PPARγ-mediated activities. Enforced PPARγ expression sufficiently rescued metabolic and functional defects of Pim1-/- MDSCs. Consistent with this, pharmacologic inhibition of PIM kinase by AZD1208 treatment significantly disrupted the myeloid cell-mediated immunosuppressive microenvironment and unleashed CD8+ T-cell-mediated antitumor immunity, which enhanced PD-L1 blockade in preclinical cancer models. PIM kinase inhibition also sensitized nonre
