Gastric electrical stimulation (GES) is a widely accepted therapy for gastroparesis symptoms, but how a brief cutaneous electrogastrogram (EGG) can be used in conjunction with GES has not been well defined. We evaluated the clinical importance of EGG, its correlation with mucosal electrograms (mEGs), gastric emptying tests (GETs), and gastrointestinal symptoms before and after temporary GES (tGES). ⋯ The Clinicaltrials.gov registration number for the study is NCT03876288.

To evaluate if electrodiagnostic tools can advance the understanding in the effect of sacral neuromodulation (SNM) on pelvic floor activity, more specifically if SNM induces changes in pelvic floor muscle (PFM) contraction. ⋯ This is the first study to describe in detail the neurophysiological characteristics of the PFM, and the changes over time upon sacral spinal root stimulation, in responders and nonresponders to SNM. More research is needed to investigate the full potential of EPFMR as a response indicator.

Transcutaneous Electrical Acustimulation Improved the Quality of Life in Patients With Diarrhea-Irritable Bowel Syndrome.
Patients with diarrhea-dominant irritable bowel syndrome (IBS-D) experience abdominal pain and reduced quality of life and need effective treatments. This study aimed to evaluate whether transcutaneous electrical acustimulation (TEA) at two acupuncture points, LI4 and ST36, could improve pain and quality of life of patients with IBS-D. ⋯ TEA at LI4 and ST36 improves abdominal pain and quality of life of patients with IBS-D, probably mediated by mechanisms other than autonomic function or inflammatory cytokines.

Coma state and loss of consciousness are associated with impaired brain activity, particularly gamma oscillations, that integrate functional connectivity in neural networks, including the default mode network (DMN). Mechanical ventilation (MV) in comatose patients can aggravate brain activity, which has decreased in coma, presumably because of diminished nasal airflow. Nasal airflow, known to drive functional neural oscillations, synchronizing distant brain networks activity, is eliminated by tracheal intubation and MV. Hence, we proposed that rhythmic nasal air puffing in mechanically ventilated comatose patients may promote brain activity and improve network connectivity. ⋯ Rhythmic nasal air puffing, as a noninvasive brain stimulation method, opens a new window to modifying the brain connectivity integration in comatose patients. This approach may potentially influence comatose patients' outcomes by increasing brain reactivity and network connectivity.

Lack of interstitial cells of Cajal (ICC) and neuropathy were the most possible pathological mechanisms of diabetic gastroparesis. Gastric electrical stimulation (GES) is a promising way to treat gastroparesis. This study aimed to explore the impact of GES on ICC together with enteric neurons in diabetic rats and the possible mechanisms involved. ⋯ GES improves the proliferation of ICC possibly related with the 5-HT/5-HT2B signal pathway and alters the enteric nervous system partly though the GDNF expression.
