Consensus on the Management of Anesthetic Agents During Digestive Motility Measurements and Proposal of a Standardized Protocol for Anesthesia (French Neuro Gastroenterology Group GFNG and Committee of Anesthetic French Experts)

open access: yesNeurogastroenterology &Motility, EarlyView.
Anesthesia can alter measurements during digestive endoscopies, yet no standardized protocol currently exists. Two expert groups—the French Neuro‐Gastroenterology Group (GFNG) and anesthesiologists—used the Delphi method to reach a consensus on which drugs have an influence (91 amendments), ultimately resulting in a proposed anesthesia protocol (28 ...

Length of the Adult Human Colon in Health and Constipation Measured Using Magnetic Resonance Imaging

open access: yesNeurogastroenterology &Motility, EarlyView.
Colon length was measured in adult healthy volunteers, people with chronic constipation, and people with IBS with constipation using MRI. Colon length is significantly longer in chronic constipation. The chronically constipated colon is unable to accommodate longitudinally in response to fluid influx from a macrogol challenge.

Small understory trees increase growth following sustained drought in the Amazon

open access: yesNew Phytologist, EarlyView.
Summary Droughts pose a major threat to the Amazon rainforest, yet the mechanisms enabling trees to maintain growth under prolonged drought remain poorly understood, particularly in the understory layer. We leveraged a 22‐yr Throughfall Exclusion (TFE) in a 1‐ha plot in eastern Amazonia, paired with a Control plot, to test whether small understory ...
