Article Synopsis
  • Portable spirometers are becoming popular for measuring lung function at home, but there are concerns about their accuracy, which impacts the management of chronic respiratory diseases.
  • The study aimed to evaluate the accuracy, repeatability, and responsiveness of home spirometry for cystic fibrosis patients in both children and adults across multiple Dutch centers.
  • Results indicated that home spirometry measurements consistently showed lower values than clinic measurements, suggesting potential limitations in using these devices for accurate lung function assessment.

Light pulses in the femtosecond range require sophisticated methods for their precise temporal characterization. Several techniques have been developed over the past decades that deliver the temporal structure of ultrashort light pulses. Still, there are special cases left that cannot be treated directly by established methods.

Background: Remote care usefulness and climate change co-benefits should be addressed simultaneously to incentivize political action.

Objectives: To assess the changes in healthcare consumption, lung function and greenhouse gas (GHG) emissions during the COVID-19 pandemic in Dutch cystic fibrosis (CF) care.

Design: Retrospective multicentre observational study in five Dutch CF centres.

Background: The current literature inadequately addresses the extent to which remote monitoring should be integrated into care models for chronic respiratory diseases (CRDs).

Objective: This study examined a remote monitoring program (RMP) in cystic fibrosis (CF) by exploring experiences, future perspectives, and use behavior over 3 years, with the aim of developing future directions for remote monitoring in CRDs.

Methods: This was a mixed methods, multicenter, observational study in 5 Dutch CF centers following a sequential explanatory design.

Background: The highly effective Cystic Fibrosis Transmembrane conductance Regulator (CFTR) modulator, elexacaftor-tezacaftor-ivacaftor, is now widely being used by people with cystic fibrosis. However, few independent studies have detailed the pharmacokinetics (PK) of CFTR modulators. Blood collection by venipuncture is the gold standard for PK measurements, but it is invasive.
