Cell death includes programmed and nonprogrammed cell death. The former mainly includes ferroptosis, necroptosis, pyroptosis, autophagy, and apoptosis, while the latter refers to necrosis. Accumulating evidence shows that ferroptosis, necroptosis, and pyroptosis play essential regulatory roles in the development of intestinal diseases. In recent years, the incidence of inflammatory bowel disease (IBD), colorectal cancer (CRC), and intestinal injury induced by intestinal ischemia–reperfusion (I/R), sepsis, and radiation have gradually increased, posing a significant threat to human health. The advancement in targeted therapies for intestinal diseases based on ferroptosis, necroptosis, and pyroptosis provides new strategies for treating intestinal diseases. Herein, we review ferroptosis, necroptosis, and pyroptosis with respect to intestinal disease regulation and highlight the underlying molecular mechanisms for potential therapeutic applications.

Background: Emergence agitation (EA) is one of the most common and intractable postoperative complications among children undergoing surgery under general anesthesia. Dexmedetomidine, an α(2)-adrenoceptor agonist, offers an ideal sedation, reduces preoperative anxiety, and facilitates smooth induction of anesthesia, and it is widely used in pediatric surgery. We aimed to evaluate the efficacy of dexmedetomidine for preventing emergence agitation in children after general anesthesia. Methods: We comprehensively reviewed PubMed, Cochrane Library, EMBASE, and Web of Science databases to search all randomized controlled trials, published before April 22, 2020, investigating the efficacy of dexmedetomidine in preventing the emergence agitation in children after general anesthesia. The meta-analysis was performed using Review Manager 5.3. The primary outcome was the incidence of emergence agitation. Secondary outcomes included the number of patients requiring rescue analgesic, number of patients with postoperative nausea and vomiting, emergence time, extubation time, and time to discharge from the post-anesthesia care unit. Results: We included a total of 33 studies, comprising 2,549 patients in this meta-analysis. Compared with saline, dexmedetomidine significantly reduced the emergence agitation incidence [risk ratio (RR) 0.29; 95% confidence interval (CI) 0.22–0.37; p < 0.00001], incidence of postoperative nausea and vomiting (RR 0.46; 95% CI 0.3–0.69; p = 0.0002), and the requirement of rescue analgesic (RR 0.29; 95% CI 0.18–0.44; p < 0.00001). Furthermore, children in the dexmedetomidine group experienced a longer emergence time [mean difference (MD) 2.18; 95% CI 0.81–3.56; p = 0.002] and extubation time (MD 0.77; 95% CI 0.22–1.31; p = 0.006) compared with those in the saline group. However, no significant difference was observed in the time to discharge from the post-anesthesia care unit (MD 2.22; 95% CI −2.29–6.74; p = 0.33) between the two groups. No significant differences were observed between the effects of dexmedetomidine and other drugs like midazolam, propofol, fentanyl, tramadol, and clonidine in terms of the emergence agitation incidence and other parameters, except for the requirement of rescue analgesic (RR 0.45; 95% CI 0.33–0.61; p < 0.00001). Conclusions: Dexmedetomidine can prevent emergence agitation, relieves postoperative pain, decreases the requirement of rescue analgesic, and decreases the postoperative nausea and vomiting events.

Female gender has been identified as one of the risk factors closely linked to perioperative anxiety and a lower level of satisfaction. A successful preoperative anesthesia education may improve such negative outcomes. The aim of this study was to investigate whether preoperative anesthesia education via an Anesthesia Service Platform (ASP) could reduce the anxiety levels in female patients scheduled for laparoscopic cholecystectomy under general anesthesia, and accelerate rehabilitation. A total of 222 patients scheduled for elective laparoscopic cholecystectomy were randomly assigned to the control group and the ASP group. Patients’ baseline and post-intervention psychological status was measured by the State-Trait Anxiety Inventory and General Well-Being Schedule. Pain management and recovery were assessed by VAS every 12 h for 48 h after surgery; length of stay (LOS) and postoperative analgesic consumption were also assessed. Patients in the control group experienced higher anxiety levels before surgery and had longer LOS than those in the ASP group. Patients in the ASP group had a higher general well-being score; however, they suffered more pain and consumed more analgesics after surgery. ASP is effective for preventing anxiety in female patients before laparoscopic cholecystectomy, improving patients’ general well-being levels, and shortening their LOS, but negatively influences patients’ postoperative pain levels.

Objective: To investigate the efficacy of intracuff lidocaine in reducing coughing and other endotracheal tube side effects and so ensure a smooth extubation process. Method: PubMed, EMBASE, and Cochrane Library databases were systematically searched for all randomised controlled trials (RCTs) published before June 30, 2019 that investigated the efficacy of intracuff lidocaine, with or without sodium bicarbonate, in reducing coughing and other complications related to endotracheal intubation. A random-effects model was used to conduct a meta-analysis to assess the relative risks (RRs) of the incidence of these intubation-related side effects. Results: 11 studies involving 843 patients were included in the meta-analysis. Compared with control groups (i.e., saline or air), intracuff lidocaine groups (alkalinized or non-alkalinized) had a significantly reduced incidence of coughing on tube. Similarly, intracuff lidocaine groups were more effective than control groups in reducing the incidence of other intubation-related complications. Conclusion: Intracuff alkalinized or non-alkalinized lidocaine significantly reduced coughing and other intubation-related complications during the extubation process.
