Annals of surgery
Reddy MS, Koneti AJ, Chaudhary A, Rammohan A, Yalakanti RB +8 more
Plain English This study compared two surgical techniques used in liver transplants for patients receiving a portion of a liver from a living donor. Researchers found that the single outflow technique (SOT) led to a higher success rate in allowing blood to flow properly through the new liver within the first two weeks (92.5% patency compared to 82.9% with the double outflow technique, DOT) and also correlated with better immediate survival rates (97.3% vs 90.8%). These findings are important because having a more successful blood flow in the early stages after surgery can lead to better outcomes for patients.

Gopal P, Krishnan SK, Malleswaran S, Srinivas S, Mouleeswaran S +3 more
Plain English This study focused on developing a new way to identify acute liver failure caused by yellow phosphorus rodenticides, especially when patients can't provide information on what they ingested. Researchers found that patients with this type of poisoning had lower liver attenuation index (LAI) values on abdominal CT scans compared to those with liver failure from other causes, with a significant difference of -30 vs -8. Using an LAI greater than -18 can effectively rule out yellow phosphorus poisoning with 91% sensitivity and 85% specificity.
Who this helps: This helps doctors in emergency settings quickly diagnose yellow phosphorus poisoning in patients showing signs of liver failure.
