Article Synopsis
  • Minimally invasive pancreatoduodenectomy (MIPD) techniques, like robot-assisted (RAPD) and totally laparoscopic (TLPD) surgeries, are becoming more popular for treating pancreatic diseases.
  • A study comparing RAPD and TLPD found similar complication rates and survival outcomes, although RAPD was associated with shorter operation times and hospital stays.
  • The overall results suggest both methods are safe and effective, allowing surgeons to choose based on factors like technique preference, cost, and experience.

Vitamin C is a well-known antioxidant with antiviral, anticancer, and anti-inflammatory properties based on its antioxidative function. Aptamin C, a complex of vitamin C with its specific aptamer, has been reported to maintain or even enhance the efficacy of vitamin C while increasing its stability. To investigate distribution of Aptamin C, Gulo knockout mice, which, like humans, cannot biosynthesize vitamin C, were administered Aptamin C orally for 2 and 4 weeks.

Interleukin (IL)-32 is produced by T lymphocytes, natural killer cells, monocytes, and epithelial cells. IL-32 induces the production of pro-inflammatory cytokines such as tumor necrosis factor (TNF)-α, IL-1β, IL-6, and IL-8, and IL-32 expression is highly increased in rheumatoid arthritis (RA) patients. Enolase-1 (ENO1) is a glycolytic enzyme and the stimulation of ENO1 induces high levels of pro-inflammatory cytokines in concanavalin A (Con A)-activated peripheral blood mononuclear cells (PBMCs) and macrophages in RA patients.

  • Bile is typically sterile, but a study analyzed factors that may lead to bactibilia (presence of bacteria in bile) in patients undergoing cholecystectomy between November 2018 and November 2019.
  • Of 428 surgeries, 36.7% of patients tested positive for bacteria, with the most common being gram-negative species, particularly certain strains identified in the results.
  • Key risk factors for bactibilia included being 70 or older, male sex, having diabetes, jaundice, and previous procedures like ERCP and PTGBD; surgeons are advised to prevent bile leakage and consider antibiotics in these high-risk patients.

Reactive oxygen species (ROS), which are exceptionally high in IBD lesions, are known to cause abnormal immune responses to inflammatory reactions in inflammatory bowel diseases (IBD) through damage to the intestinal mucosal linings. Moreover, they are theorized to be an agent of IBD development. Vitamin C is widely known to be an effective antioxidant for its ability to regulate inflammatory responses through its ROS scavenging effect.
