The relationship between surgical difficulty and postoperative complications in kidney transplantation: establishment of a preoperative prediction model.

Introduction This study aims to investigate the relationship between surgical difficulty and postoperative complications in kidney transplantation, as well as to develop a preoperative prediction model for assessing surgical difficulty. Methods This is a prospective cohort included 122 kidney transplant adult recipients. The subjective score for operative difficulty, ranging from 1 to 3 points, served as the quantitative measure of surgical difficulty.

Effects of inorganic ions with different concentrations on the nanofiltration separation performance of perfluorobutane sulfonic acid (PFBS).

Perfluorobutane sulfonic acid (PFBS) is a kind of anthropogenic recalcitrant contaminant that has posed a threat to drinking water safety and brought widespread public health concerns. Nanofiltration (NF) is an effective way to remove PFBS from drinking water, while the removal is influenced by coexisting ions. To investigate the effects and intrinsic mechanisms of coexisting ions on the rejection of PFBS, poly(piperazineamide) NF membrane was utilized in this work.
