Abnormal composition of gut microbiota contributes to delirium-like behaviors after abdominal surgery in mice.

Aims: Anesthesia and surgery can cause delirium-like symptoms postoperatively. Increasing evidence suggests that gut microbiota is a physiological regulator of the brain. Herein, we investigated whether gut microbiota plays a role in postoperative delirium (POD).

Relationship between Volatile Anesthetics and Tumor Progression: Unveiling the Mystery.

A series of factors can be involved in the perioperative period to cause an increase in cancer-related mortality. Unfortunately, volatile anesthesia might aggravate the deleterious effects. In this article, we review the association of diverse volatile anesthetic agents with immune system and cancer cell biology, and examine the effects on angeogenesis and postoperative metastasis or recurrence.
