Exploratory analyses of treatment subgroup interaction by PD-L1 status and according to PD-L1 expression in the JAVELIN Bladder 100 trial.

Purpose: Post hoc analysis of the JAVELIN Bladder 100 trial of avelumab maintenance in locally advanced/metastatic urothelial carcinoma (la/mUC) to determine the interaction by programmed death ligand 1 (PD-L1) status for overall survival (OS), and additional analyses of survival per a different PD-L1 expression cutoff of ≥ 1% in tumor cells or immune cells (TC/IC).

Methods: JAVELIN Bladder 100 data were used for the analysis of the interaction by PD-L1 status (per cutoff used in the trial) for OS and, additionally, OS and progression-free survival (PFS) analyses per a different ≥ 1% TC/IC PD-L1 expression cutoff (Ventana SP263 assay).

Results: No significant interaction between treatment and PD-L1 status was observed for OS.

Tracking Waste Management Information Disclosure Behavior Connected to Financial Performance through Moderating Variables.

The current challenges of a circular economy exert a high pressure on manufacturing companies that generate waste to track and implement policies to reduce them and eliminate the toxicity of residues. Hence, the purpose of this study is to analyze the waste management information disclosure linked to the financial performance of companies and test the moderating effect of internal and external variables. The average waste management information disclosure index shows a poor disclosure score for the analyzed period, however, the waste disclosure index after reaching a minimum threshold in 2019 recorded an encouraging increase at the end of 2021.

Recent therapeutic advances in urothelial carcinoma: A paradigm shift in disease management.

Management of first-line advanced urothelial carcinoma (UC) has consisted during the past three decades in the administration of platinum-based chemotherapy followed by observation. Despite moderate to high response rates to first-line treatment, most patients will relapse shortly after and the outcomes with subsequent therapies are poor with 5-year overall survival rates of 5% in the pre-immunotherapy era. Nonetheless, recent therapeutic developments including the paradigm shift of first-line maintenance therapy with avelumab after response or stabilization on platinum-based chemotherapy, along with the incorporation of new drug classes in further lines of treatment such as antibody drug-conjugates and fibroblast growth factor receptor inhibitors have reshaped the field leading to better outcomes in this patient population.

p38 activation occurs mainly in microglia in the P301S Tauopathy mouse model.

Tauopathies are a group of neurodegenerative diseases characterized by the accumulation of hyperphosphorylated tau protein in the brain. Many of these pathologies also present an inflammatory component determined by the activation of microglia, the resident immune cells of the brain. p38 MAPK is one of the molecular pathways involved in neuroinflammation.

p38 Inhibition Decreases Tau Toxicity in Microglia and Improves Their Phagocytic Function.

Alzheimer's disease (AD) and other tauopathies are histopathologically characterized by tau aggregation, along with a chronic inflammatory response driven by microglia. Over the past few years, the role of microglia in AD has been studied mainly in relation to amyloid-β (Aβ) pathology. Consequently, there is a substantial knowledge gap concerning the molecular mechanisms involved in tau-mediated toxicity and neuroinflammation, thus hindering the development of therapeutic strategies.
