Association between Paravertebral Block and Pain Score at the Time of Hospital Discharge in Oncoplastic Breast Surgery: A Retrospective Cohort Study.

Background: Using nonopioid analgesics may decrease the risk of patients chronically using opioids postoperatively. The authors evaluated the relationship between paravertebral block and pain score at the time of hospital discharge.

Methods: The authors performed a retrospective cohort study of 89 women with American Society of Anesthesiologists Physical Status I to III undergoing oncoplastic breast surgery with 20 to 50 percent breast tissue removal and immediate contralateral reconstruction between August of 2015 and August of 2018.

NMDA receptors are important regulators of pancreatic cancer and are potential targets for treatment.

Pancreatic cancer, particularly adenocarcinoma of the pancreas, is a common disease with a poor prognosis. In this study, the importance of N-methyl-D-aspartate (NMDA) receptors for the growth and survival of pancreatic cancer was investigated. Immunohistochemistry performed with antibodies against GluN1 and GluN2B revealed that all invasive adenocarcinoma and neuroendocrine pancreatic tumors likely express these two NMDA receptor proteins.
