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.

Controlled Clinical Trial Observational Study
The Clinical Efficacy of High-Voltage Long-Duration Pulsed Radiofrequency Treatment in Pudendal Neuralgia: A Retrospective Study.
Patients with pudendal neuralgia (PN) experience long-lasting chronic pain, hyperalgesia, and comorbid emotional disorders, such as depression and anxiety. Treatment via conventional pulsed radiofrequency (PRF) current carries a significantly high rate of failure. ⋯ High-voltage long-duration PRF provided significant short-term (at least 12 weeks) pain relief to most patients with PN; it also improved subjective measures of depression and quality of life over the same duration of time.

In the United States, more than 14 million adults suffer from alcohol use disorder (AUD). We proposed a stress-free method of electroacupuncture (EA) using chronically implanted electrodes. We aimed to develop an effective method of EA for treating AUD by testing various stimulation locations and parameters, and then investigate the effects of the daily EA on alcohol consumption and withdrawal signs in rats. ⋯ This work shows the potential of this novel method of EA for the treatment of AUD. Further studies are warranted to investigate the mechanisms through which EA exerts its effects.

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.

This study aimed to assess the neurophysiological basis behind troubleshooting in sacral neuromodulation (SNM). Close follow-up of SNM patients with program parameter optimization has proven to be paramount by restoring clinical efficacy and avoiding surgical revision. ⋯ From a neurophysiological point of view, monopolar configurations stimulated more motor nerve fibers at lower STs, therefore providing more therapeutic efficiency. Swapping polarity or changing the position of the cathode led to different sensory and motor responses, serving as potential reprogramming options.
