Select Drug Category Opiates/Opioids Topic Tolerance/Dependence Abstract Detail Clinical - Epidemiology Abstract Category Original Research Characterize the relationship between intraoperative opioid administration and postoperative pain and opioid requirements. We conducted a retrospective cohort study of 61,250 adult patients who received non-cardiac surgery under general anesthesia at a quaternary care center between 2016 and 2020. The exposure variable was intraoperative fentanyl and intraoperative hydromorphone average effect site concentration. The primary study outcomes were maximal pain score during post-anesthesia care unit (PACU) stay and cumulative opioids administered in the PACU in morphine milligram equivalents (MME). Secondary outcomes included frequency of uncontrolled pain at 24 hours, new instances of chronic pain diagnosis, total opioid use at 24 hours and in-hospital, opioid prescriptions at 30, 90, and 180 postoperative days, frequency of new persistent opioid use, maximal pain score in the first 24 hours and in-hospital, and incidence of opioid related complications in PACU. We used multivariate propensity weighting to control for confounding and estimated the counterfactual difference in outcomes after administration of an additional 100 mcg fentanyl or 500 mcg hydromorphone intraoperatively. Increased intraoperative fentanyl and intraoperative hydromorphone were both associated with reduced maximum pain scores in the PACU. Both exposures were also associated with a reduced probability and reduced total dosage of opioid administration in the PACU. We found that increased fentanyl administration in particular was associated with lower frequency of uncontrolled pain, decreased chronic pain at 3-months, fewer opioid prescriptions at 30-, 90-, and 180-days, and decreased persistent opioid use, without significant increases in side effects. Our results show that intraoperative opioid administration is significantly associated with short- and long-term effects on post-operative pain and opioid outcomes. Contrary to prevailing trends, reduced opioid administration during surgery may have the unintended consequence of increasing postoperative pain and opioid consumption. Our analysis suggests that significant improvements in long-term outcomes might be achieved by optimizing opioid administration during surgery. [ABSTRACT FROM AUTHOR]

Background: It has been reported that expression of OCT3 enhanced the sensitivity to melphalan in cells, indicative of potential roles of OCT3 in melphalan transport. Herein we investigated the association of select single nucleotide polymorphisms in SLC22A3 (gene encoding OCT3) with clinical outcomes in multiple myeloma (MM) patients with hematopoietic autologous stem cell transplants followed by high-dose melphalan therapy., Materials and Methods: Melphlan concentrations in blood samples from 108 MM patients were measured using liquid chromatography-tandem mass spectrometry (LC-MS/ΜS); genotypes of rs2048327, rs1810126, and rs3088442 in these patients were determined using quatitive RT-PCR assays., Results: Rs3088442 A variant-carriers had a significantly increased risk of severe oral mucositis in comparison with homozygous rs3088442 G-carriers with adjusted odds ratio of 4.00 (95% CI=1.25-14.7; p=0.027). Rs3088442 A carriers tended to have lower creatinine clearance (p=0.10) and higher maximum plasma concentration of melphalan (p=0.07)., Conclusion: OCT3 might be involved in melphalan transport in MM patients., (Copyright © 2022 International Institute of Anticancer Research (Dr. George J.

Background/aim: SLC7A5 is recognized as the major mediator of melphalan uptake into multiple myeloma (MM) cells; however, its contribution to the inter-patient variability of melphalan efficacy and toxicity is yet to be well elucidated. This study aimed to investigate the impact of a single nucleotide polymorphism (SNP) rs4240803 in SLC7A5 on the gene expression, ex vivo sensitivity to melphalan, and clinical outcomes in MM patients who were undergoing autologous stem cell transplantation with high-dose melphalan., Materials and Methods: Peripheral blood mononuclear cells (PBMC) were collected from 108 MM patients prior to melphalan therapy. Clinical data were also collected from these patients following melphalan therapy., Results: rs4240803 was associated with elevated expression of SLC7A5 mRNA, higher ex vivo sensitivity to melphalan in PBMCs, and positive 90-day response in these patients (p=0.047, 0.10, 0.049, respectively)., Conclusion: rs4240803 impacted the expression of SLC7A5, thus contributing to the clinical response of MM patients to melphalan therapy., (Copyright© 2019, International Institute of Anticancer Research (Dr. George J.
