Nonsteroidal anti-inflammatory drugs (NSAIDs) and cyclooxygenase (COX)-2-specific inhibitors provide significant analgesic and opioid-sparing benefits. However, these analgesics are commonly avoided owing to concerns of potential adverse effects. The evidence for NSAID-related adverse effects is conflicting and of poor quality, and these analgesics are safer than what has been implied.

Introduction: Postoperative ileus is a severe condition occurring especially in high-risk patients following acute and prolonged surgical procedures. Multiple factors are described as important in etiology, such as inflammation as well as neurological, hormonal and pharmacological influences. In prevention and treatment, we try to apply non-pharmaceutical procedures, to influence reversible etiological factors and, in post-operative period, to implement and use ERAS procedures.

Receptor-interacting serine/threonine protein kinase 2 (RIPK2) is a kinase that is essential in modulating innate and adaptive immune responses. As a downstream signaling molecule for nucleotide-binding oligomerization domain 1 (NOD1), NOD2, and Toll-like receptors (TLRs), it is implicated in the signaling triggered by recognition of microbe-associated molecular patterns by NOD1/2 and TLRs. Upon activation of these innate immune receptors, RIPK2 mediates the release of pro-inflammatory factors by activating mitogen-activated protein kinases (MAPKs) and nuclear factor-kappa B (NF-κB).

Article Synopsis
  • The study examined markers of inflammation and placental development in relation to COVID-19's effects on pregnancy and fetal development.
  • Researchers analyzed placental tissue from 170 women categorized into groups based on COVID status and vaccination.
  • Findings showed that CD44, OPN, and COX-2 expressions varied by group, with significant alterations observed in those who were COVID-positive, indicating potential impacts on placental structure and function.
