Exercise-Induced Oxygen Desaturation and Outcomes After Nintedanib Therapy for Fibrosing Interstitial Lung Disease in Patients Without Dyspnea.

The degree of exercise-induced oxygen desaturation and outcomes following antifibrotic drug therapy in asymptomatic patients with fibrosing interstitial lung disease (FILD) remain unclear. We compared clinical data, incidence of annual FILD progression, overall survival, and tolerability after initiating nintedanib between 58 patients with dyspnea and 18 patients without. Annual FILD progression was defined as >10% decrease in forced vital capacity (FVC), >15% decrease in diffusing capacity of the lungs for carbon monoxide (D), developing acute exacerbations, or FILD-related death within 1 year of starting nintedanib.

A multicenter study on TROP2 as a potential targeted therapy for extramammary Paget disease in Japan.

Extramammary Paget disease (EMPD) is a rare skin cancer that typically occurs in the anogenital area of older people. Since efficacy of treatments for metastatic or unresectable EMPD remains poor, development of a novel therapeutic approach is strongly desired. However, the lack of EMPD models has hampered investigation of EMPD.

Prevalence, management, health-care burden, and 90-day outcomes of prolonged mechanical ventilation in the paediatric intensive care unit (LongVentKids): an international, prospective, cross-sectional cohort study.

Background: The number of children requiring prolonged mechanical ventilation (PMV) has increased with the advancement of medical care. We aimed to estimate the prevalence of PMV worldwide, document demographic and clinical characteristics of children requiring PMV in paediatric intensive care units (PICUs), and to understand variation in clinical practice and health-care burden.

Methods: This international, multicentre, cross-sectional cohort study screened participating PICUs in 28 countries for children aged >37 postgestational weeks to 17 years who had been receiving mechanical ventilation (MV; invasive or non-invasive) for at least 14 consecutive days.

Single-cell RNA-seq reveals diverse molecular signatures associated with Methotrexate resistance in primary central nervous system lymphoma cells.

Purpose: Methotrexate is one of the most essential single agents in patients with primary central nervous system lymphoma (PCNSL). However, 25-50% result in relapse with a poor prognosis. Therefore, studies on methotrexate resistance are warranted to explore salvage chemotherapy for recurrent PCNSL.
