RESUMO

BACKGROUND: Bowel disease is a significant cause of significant morbidity and mortality around the world. Though colorectal cancer is a major cause for concern, there are a variety of other conditions which are chronic, debilitating and/or socially embarrassing. While the internet provides excellent resources, there is often conflicting and confusing material of doubtful veracity. There is pressing need for trainees and patients/carers to be able to access reliable resources whenever and wherever they are. AIM: To create an integrated, interactive platform providing reliable information on aspects of bowel disease for patients while addressing educational needs of surgical trainees and other healthcare professionals. APPROACH: Since 2006, we have progressed from leaflets, diagrammatic booklets to DVDs and then downloadable applications all of which, though very successful, had significant limitations.Trainees struggle with balancing their educational needs with their service commitments. This online resource, www.colorectaleducation.com provides an opportunity to view detailed operative training videos on the go. The website also hosts detailed chapterised information videos for patients, care pathway videos and patient experiences. The modular design of the website allows for ease of updating and sequential expansion. The initial emphasis has been on colorectal cancer and the site is being gradually expanded to include a variety of other conditions. RESULTS: The website gained widespread popularity with Google Analytics revealing steadily rising global hit rate with very low bounce rate for both sections. Structured feedback showed 96% satisfaction on both patient and professional sections. CONCLUSION: On-demand information became the norm with the use of smartphones/tablets. This website provides patients, surgical trainees and healthcare professionals access to information and education in clear reliable format, anywhere in the world. This is particularly relevant now as pandemic reduced opportunities for face to face patients consultations as well as for learners with educators.

RESUMO

The omega-3 fatty acid eicosapentaenoic acid (EPA) is a superb nature's medicine, with still unfolding health benefits. Because hepatotoxicity is a prominent adverse drug reaction, we currently attempted a new approach in which EPA was challenged to both alleviate hepatotoxicity and provide synergy with anticonvulsant effects of valproate (VPA). Besides, we verified whether EPA may kinetically modulate the clearance rate of VPA. VPA (500mg/kg p.o., for 2weeks) caused rat hepatotoxicity that was manifested as notable (2- to 4-fold) rise in serum liver enzymes (GGT, ALT, and ALP), increased hepatic levels of lipid peroxides and TNF-α (3- and 7-fold) and activity of myeloperoxidase (MPO, 4-fold), lowering of serum albumin (42%), and depletion of liver reduced glutathione (GSH, 36%). Furthermore, histopathologic examination revealed hepatocellular degeneration, focal pericentral necrosis, infiltration of inflammatory cells, and steatosis. Joint treatment with EPA (300mg/kg) blunted the oxidative stress, TNF-α levels and MPO activity, while enhanced levels of serum albumin and hepatic GSH. EPA also ameliorated most of the hepatocellular anomalies evoked by VPA. Additionally, in a mouse PTZ convulsion model, EPA markedly augmented the anticonvulsant effects of VPA far beyond their single responses. On the other hand, pharmacokinetic analyses revealed that joint EPA administration had no effect on serum VPA concentrations. Collectively, results demonstrate for the first time that the ω-3 FA (EPA) markedly alleviated VPA-induced hepatotoxicity, oxidative stress, and inflammation, while enhanced its anticonvulsant effects without altering its clearance. Therapeutically, these protective and synergy profiles for EPA foster a more safe and efficacious drug combination regimen than VPA.
