Lengthening Adalimumab Dosing Interval in Quiescent Crohn's Disease Patients

Oct 14th, 2022 - Rationale Adalimumab is both an effective induction and maintenance therapy for Crohn's disease (CD). Due to the risk of side effects (infections, injection reaction) and high costs, an extension of the injection interval is an attractive option. However, this strategy has not been evaluated yet in a randomized controlled trial in CD patients. Objective To assess non-inferiority and cost-effect...

Nasal High-frequency Oscillatory Ventilation (NHFOV) for Ventilated Newborn Infants With BPD

Oct 14th, 2022 - Supplying with the combined advantages of NCPAP and high-frequency oscillatory ventilation (HFOV) with high carbon dioxide(CO2) removal, no need for synchronisation, non-invasion, less volume/barotraumas, and increased functional residual capacity, nasal HFOV(NHFOV) was considered as a strengthened version of NCPAP. Furthermore, the superimposed oscillations of NHFOV could avoid gas-trapping, a...
