Objectives: We aimed to evaluate the effect of frailty on lung function and disease outcomes in older adults with chronic obstructive pulmonary disease (COPD).
Design: Retrospective observational cohort.
Setting And Participants: At baseline, comprehensive geriatric assessment and pulmonary function tests were extracted from the case management care system of the geriatric department of a tertiary medical center.
Measurements: Frailty was assessed by the modified Rockwood frailty index. Kaplan-Meier survival and Cox proportional hazard analyses were used to analyze the primary outcome. Both the Friedman test and generalized estimating equations were used to evaluate the rate of decline in lung function.
Results: Among 151 enrolled older patients, comprising 69 non-COPD and 82 COPD subjects, the mean age was 80.9±8.3 years. After a median follow-up of 2.87 years, the serial forced expiratory volume in 1 s/forced vital capacity (FEV1/FVC), and forced expiratory flow at 25-75% of FVC (FEF25-75%) showed significantly different slope changes between older COPD patients with and without frailty. The mortality hazard ratio (HR) was 2.53 for COPD without frailty and 3.62 for COPD with frailty, versus those without COPD. Among COPD patients, the factors most strongly associated with mortality were timed up-and-go, activities of daily living (ADLs), instrumental ADLs, FEV1/FVC, and serum HCO3-. After adjustment for potential confounders, ADLs and FEV1/FVC remained independent mortality predictors.
Conclusion: Among older patients with COPD, frailty was common and associated with pulmonary function decline, and mortality risk was higher in frail than in non-frail subjects.

Background: Senescence classification is an acknowledged challenge within the field, as markers are cell-type and context dependent. Currently, multiple morphological and immunofluorescence markers are required. However, emerging scRNA-seq datasets have enabled an increased understanding of senescent cell heterogeneity.

Background: Germline heterozygous pathogenic variants (PVs) in TP53 cause Li-Fraumeni syndrome (LFS), a condition associated with increased risk of multiple tumor types. As the associated cancer risks were refined over time, clinical criteria also evolved to optimize diagnostic yield. The implementation of multi-gene panel germline testing in different clinical settings has led to the identification of TP53 PV carriers outside the classic LFS-associated cancer phenotypes, leading to a broader cancer phenotypic redefinition and to the renaming of the condition as "heritable TP53-related cancer syndrome" (hTP53rc).

Background: Patients with lung adenocarcinoma (LUAD) receiving drug treatment often have an unpredictive response and there is a lack of effective methods to predict treatment outcome for patients. Dendritic cells (DCs) play a significant role in the tumor microenvironment and the DCs-related gene signature may be used to predict treatment outcome. Here, we screened for DC-related genes to construct a prognostic signature to predict prognosis and response to immunotherapy in LUAD patients.

B cells have emerged as central players in the tumor microenvironment (TME) of non-small cell lung cancer (NSCLC). However, although there is clear evidence for their involvement in cancer immunity, scanty data exist on the characterization of B cell phenotypes, bioenergetic profiles and possible interactions with T cells in the context of NSCLC. In this study, using polychromatic flow cytometry, mass cytometry, and spatial transcriptomics we explored the intricate landscape of B cell phenotypes, bioenergetics, and their interaction with T cells in NSCLC.
