Does using the Lung Clearance Index (LCI) inform clinical decisions in children with cystic fibrosis?

Introduction: The Lung Clearance Index (LCI) is an established research test, but its role in clinical decision-making is not well defined. This study estimated the proportion of treatment decisions that are changed or supported by the added information provided by LCI.

Methods: A mixed methods prospective observational study was conducted in North America.

Unraveling climate change-induced compound low-solar-low-wind extremes in China.

China's pursuit of carbon neutrality targets hinges on a profound shift towards low-carbon energy, primarily reliant on intermittent and variable, yet crucial, solar and wind power sources. In particular, low-solar-low-wind (LSLW) compound extremes present a critical yet largely ignored threat to the reliability of renewable electricity generation. While existing studies have largely evaluated the impacts of average climate-induced changes in renewable energy resources, comprehensive analyses of the compound extremes and, particularly, the underpinning dynamic mechanisms remain scarce.

Trajectory of Depressive Symptoms in a Longitudinal Stroke Cohort.

Objectives: Knowledge of the trajectory of post-stroke depression is important to identify high-risk patients, develop precise management programs and enhance prognosis. We aimed to characterise the course of depressive symptoms within the first year post-stroke and to evaluate associations with time.

Materials And Methods: Depressive symptoms were measured using the Montgomery-Åsberg Depression Rating Scale (MADRS) within the first week, and at 3- and 12-months post-stroke.

Building materials could store more than 16 billion tonnes of CO annually.

Achieving net-zero greenhouse gas emissions likely entails not only lowering emissions but also deploying carbon dioxide (CO) removal technologies. We explored the annual potential to store CO in building materials. We found that fully replacing conventional building materials with CO-storing alternatives in new infrastructure could store as much as 16.

Birthdate aligns vestibular sensory neurons with central and motor partners across a sensorimotor reflex circuit for gaze stabilization.

Developing populations of connected neurons often share spatial and/or temporal features that anticipate their assembly. A unifying spatiotemporal motif might link sensory, central, and motor populations that comprise an entire circuit. In the sensorimotor reflex circuit that stabilizes vertebrate gaze, central and motor partners are paired in time (birthdate) and space (dorso-ventral).
