Nitrogen single and multiple breath washout test and lung imaging to detect treatment-related pulmonary toxicity in paediatric cancer patients and survivors: a systematic review

European Respiratory Review
Background Spirometry-based assessment of pulmonary function has limitations in detecting pulmonary toxicity following cancer treatment with chemotherapy, haematopoietic stem cell transplantation, radiotherapy or thoracic surgery.

Optimizing Analysis of Stable Isotope Breath Tests to Estimate Gastric Emptying of Solids

Neurogastroenterology and Motility, 2009
Breath tests (BT) using 13C–substrates have been proposed for the measurement of gastric emptying (GE). The mathematical analysis of the breath 13CO2 excretion that most accurately predicts GE t1/2 from simultaneous scintigraphy is unresolved. To compare

A Geometrically Transient Platform for Bioelectronic Implants

Advanced Materials, EarlyView.
Minimally invasive bioelectronic implants often compromise performance for smaller sizes. To resolve this optimization dilemma, a wireless bioelectronic implant with a transient geometry is introduced (MiFi). The origami‐inspired device miniaturizes up to sixfold for syringe insertion and autonomously unfolds post‐implantation.

From Fiber Bundles to Architected Membranes: Triply Periodic Minimal Surface Architectures for Biohybrid Artificial Lungs

Advanced Materials, EarlyView.
Additively manufactured triply periodic minimal surface (TPMS) membranes offer an architecture‐driven alternative to hollow fiber bundles in artificial lungs. Multiphysics simulations and endothelialized prototypes show that the 3D‐printable membrane architecture improves gas exchange, blood flow distribution, and hemocompatibility, enabling ...
