Background A minority of patients receiving stereotactic body radiation therapy (SBRT) for non-small cell lung cancer (NSCLC) are not good responders. Radiomic features can be used to generate predictive algorithms and biomarkers that can determine treatment outcomes and stratify patients to their therapeutic options. This study investigated and attempted to validate the radiomic and clinical features obtained from early-stage and oligometastatic NSCLC patients who underwent SBRT, to predict local response.

Objectives: We applied three electronic triggers to study frequency and contributory factors of missed opportunities for improving diagnosis (MOIDs) in pediatric emergency departments (EDs): return visits within 10 days resulting in admission (Trigger 1), care escalation within 24 h of ED presentation (Trigger 2), and death within 24 h of ED visit (Trigger 3).
Methods: We created an electronic query and reporting template for the triggers and applied them to electronic health record systems of five pediatric EDs for visits from 2019. Clinician reviewers manually screened identified charts and initially categorized them as "unlikely for MOIDs" or "unable to rule out MOIDs" without a detailed chart review.
Extensive but Steroid-sensitive Pulmonary Infiltration by Natural Killer-large Granular Lymphocytic Leukemia.

A 51-year-old woman with persistent proliferation of natural killer (NK) cells in her peripheral blood was diagnosed with NK-large granular lymphocytic leukemia (NK-LGLL). During follow-up, computed tomography revealed multiple infiltrative pulmonary lesions. A flow cytometric analysis of bronchoalveolar lavage fluid showed infiltration of NK cells, resulting in a diagnosis of pulmonary infiltration by NK-LGLL.

Single-cell analysis reveals ESX-1-mediated accumulation of permissive macrophages in infected mouse lungs.

(MTB) ESX-1, a type VII secretion system, is a key virulence determinant contributing to MTB's survival within lung mononuclear phagocytes (MNPs), but its effect on MNP recruitment and differentiation remains unknown. Here, using multiple single-cell RNA sequencing techniques, we studied the role of ESX-1 in MNP heterogeneity and response in mice and murine bone marrow-derived macrophages (BMDM). We found that ESX-1 is required for MTB to recruit diverse MNP subsets with high MTB burden.
