Acquisition of discrete immune suppressive barriers contributes to the initiation and progression of preinvasive to invasive human lung cancer.

Computerized chest tomography (CT)-guided screening in populations at risk for lung cancer has increased the detection of preinvasive subsolid nodules, which progress to solid invasive adenocarcinoma. Despite the clinical significance, there is a lack of effective therapies for intercepting the progression of preinvasive to invasive adenocarcinoma. To uncover determinants of early disease emergence and progression, we used integrated single-cell approaches, including scRNA-seq, multiplexed imaging mass cytometry and spatial transcriptomics, to construct the first high-resolution map of the composition, lineage/functional states, developmental trajectories and multicellular crosstalk networks from microdissected non-solid (preinvasive) and solid compartments (invasive) of individual part-solid nodules.

Evaluating the User-Perceived Benefit of a Virtual Lung Cancer Patient Education and Support Community: LVNG With Lung Cancer.

Background: The accessibility and quality of network support for people living with lung cancer (PLW) and their support partners (SP) can vary. Virtual platforms provide unique opportunities for PLW/SP peer support and disease education.

Methods: Using a novel dual approach, we determined the user-perceived impact of the AstraZeneca-sponsored Facebook community, (facebook.

Early Reinitiation of Obesity Pharmacotherapy Post Laparoscopic Sleeve Gastrectomy in Youth: A Retrospective Cohort Study.

Background: Bariatric surgery is the most effective intervention for severe pediatric obesity, but a subset of youth experience suboptimal weight loss and/or recurrent weight gain. Early re-initiation of obesity pharmacotherapy postoperatively may improve outcomes, though this has not been evaluated in pediatric populations.

Methods: A retrospective cohort study at a tertiary care children's hospital evaluated the safety and efficacy of reintroducing obesity pharmacotherapy within six weeks after laparoscopic sleeve gastrectomy (LSG).

Hypertensive Response to Exercise in Normotensive Men and Women with Abdominal Obesity: Association with Subclinical Adverse Cardiac Remodeling.

Hypertensive response to exercise (HRE) is an established risk factor for cardiovascular events. HRE is prevalent among people with excess adiposity. Both obesity and HRE have been individually associated with adverse cardiac remodeling.
