Local and network changes after multichannel transcranial direct current stimulation using magnetoencephalography in patients with refractory epilepsy.

Objective: Non-invasive neuromodulation techniques, particularly transcranial direct current stimulation (tDCS), are promising for drug-resistant epilepsy (DRE), though the mechanisms of their efficacy remain unclear. This study aims to (i) investigate tDCS neurophysiological mechanisms using a personalized multichannel protocol with magnetoencephalography (MEG) and (ii) assess post-tDCS changes in brain connectivity, correlating them with clinical outcomes.

Methods: Seventeen patients with focal DRE underwent three cycles of tDCS over five days, each consisting of 40-minute stimulations targeting the epileptogenic zone (EZ) identified via stereo-EEG.

Long-term results of laparoscopic Heller-Dor for esophageal-gastric junction outflow obstruction: a prospective comparative study.

Background: The aim of this prospective, controlled study was to assess the 5-year follow-up of Laparoscopic Heller-Dor (LHD) in patients with esophago-gastric junction outflow obstruction (EGJOO), compared with achalasia patients (ACH). The management of EGJOO reflects the experience gained with esophageal achalasia, for which LHD has been proven to be an effective long-term treatment. Prospective long-term results of LHD in EGJOO patients are still lacking.

Delta-integrated relaxation pressures as a new high-resolution manometry metric to predict the positive outcome of laparoscopic Heller-Dor in patients with achalasia.

Background: There is no consensus on the definition of failure after treatment in patients with achalasia. The Eckardt score is used to define clinical outcomes. However, objective metrics are lacking.

Laparoscopic fundoplication improves esophageal motility in patients with gastroesophageal reflux disease: a high-volume single-center controlled study in the era of high-resolution manometry and 24-hour pH impedance.

Background: Most existing literature studies reported that laparoscopic fundoplication (LF) is safe in the setting of ineffective or weak peristalsis. However, the effect of the wrap on esophageal motility is still debated. This study aimed to assess how a functioning and effective fundoplication could affect esophageal motility in patients with gastroesophageal reflux disease (GERD).

White matter microstructure in obesity and bipolar disorders: an ENIGMA bipolar disorder working group study in 2186 individuals.

Although specific risk factors for brain alterations in bipolar disorders (BD) are currently unknown, obesity impacts the brain and is highly prevalent in BD. Gray matter correlates of obesity in BD have been well documented, but we know much less about brain white matter abnormalities in people who have both obesity and BD. We obtained body mass index (BMI) and diffusion tensor imaging derived fractional anisotropy (FA) from 22 white matter tracts in 899 individuals with BD, and 1287 control individuals from 20 cohorts in the ENIGMA-BD working group.
