The mortality rate caused by organophosphate (OP) poisoning is still high, even the standard treatment such as atropine and oxime improves a lot. To search for alternative therapies, this study was aimed to investigate the effects of packed red blood cell (RBC) transfusion in acute OP poisoning, and compare the therapeutic effects of RBCs at different storage times.Patients diagnosed with OP poisoning were included in this prospective study. Fresh RBCs (packed RBCs stored less than 10 days) and longer-storage RBCs (stored more than 10 days but less than 35 days) were randomly transfused or not into OP poisoning patients. Cholinesterase (ChE) levels in blood, atropine usage and durations, pralidoxime durations were measured.We found that both fresh and longer-storage RBCs (200-400 mL) significantly increased blood ChE levels 6 hours after transfusion, shortened the duration for ChE recovery and length of hospital stay, and reduced the usage of atropine and pralidoxime. In addition, fresh RBCs demonstrated stronger therapeutic effects than longer-storage RBCs.Packed RBCs might be an alternative approach in patients with OP poisoning, especially during early stages.

Efficacy of fresh packed red blood transfusion in organophosphate poisoning.

Identification of new prognostic biomarkers and therapeutic targets is of crucial importance for patients with osteosarcoma. Cyclin-dependent kinase 5 (CDK5) is overexpressed in several tumor types. However, the exact role CDK5 plays in osteosarcoma is still unknown.

Potential mechanisms underlying CDK5 related Osteosarcoma progression.

This study aimed to compare the efficacy of thromboelastography (TEG) and conventional coagulation methods in predicting hemorrhage risk in patients with leukemia.A total of 226 patients diagnosed with leukemia were included and divided into bleeding and nonbleeding groups. All patients had their blood samples taken for TEG test to measure the reaction time (R time), alpha (α angle), and maximum amplitude (MA) as well as measure platelet count (PLT), prothrombin time, and activated partial thromboplastin time. Patients were followed up for bleeding episodes.The multivariate analysis showed that PLT [odds ratio (OR) = 0.993] and MA (OR = 0.921) have better association with bleeding risk. Receiver operating characteristic (ROC) analysis showed that the combination of PLT and MA (AUC = 0.824) was better for hemorrhage risk prediction than PLT [area under the curve (AUC) = 0.730] and MA (AUC = 0.819) alone.The combination of TEG and conventional coagulation methods could help in assessing the risk of hemorrhage in patients with leukemia.
