Key Points

  • Recent research suggests that vitamin B1, or thiamine, may play a significant role in regulating gut motility, potentially affecting bowel movement frequency.
  • A study conducted in England found that the Monarch external trigeminal nerve stimulation device may not be effective in treating ADHD symptoms, as there were no significant differences between the real device and a sham device.
  • The United States has officially withdrawn from the World Health Organization, raising concerns about the impact on global health initiatives and America's public health security.
