The future private gastroenterology practice will be a large multidisciplinary practice including a clinic, AEC, pathology services, infusion services, anesthesia services, pharmacy services, and imaging centers. Delivery of gastrointestinal (GI) services will be a team-based clinic with AEC access and improved quality of care. Competing technologies will drive practices to promote the value of colonoscopy as the best screening test for colon cancer.

Article Synopsis
  • Current bowel prep for colonoscopies typically involves a clear liquid diet (CLD) and large laxative volumes, which can discourage patients from scheduling screenings.
  • A study comparing low-residue diet (LRD) and CLD with a split dose magnesium citrate showed no significant difference in preparation quality but higher satisfaction in the LRD group.
  • The findings suggest LRD is a better dietary option for patients undergoing colonoscopies, as it improves satisfaction without compromising preparation quality.

Article Synopsis
  • Arginine vasopressin (AVP) is a hormone that plays a crucial role in maintaining blood pressure and is used therapeutically for hypotensive patients, but its mechanisms of action are still not fully understood.
  • This study explores the hypothesis that KCNQ potassium channels mediate the vasoconstrictor effects of AVP, with specific KCNQ channels expressed in rat mesenteric artery smooth muscle cells.
  • Results show that AVP suppresses KCNQ currents, leading to artery constriction, and that certain drugs can enhance or reverse these effects, indicating a complex interaction influenced by protein kinase C and calcium channels.
