Impact of Genetic Variants on Postoperative Pain and Fentanyl Dose Requirement in Patients Undergoing Major Breast Surgery: A Candidate Gene Association Study.
Postoperative analgesia is crucial for the early and effective recovery of patients undergoing surgery. Although postoperative multimodal analgesia is widely practiced, opioids such as fentanyl are still one of the best analgesics. The analgesic response of fentanyl varies widely among individuals, probably due to genetic and nongenetic factors. Among genetic factors, single nucleotide polymorphisms (SNPs) may influence its analgesic response by altering the structure or function of genes involved in nociceptive, fentanyl pharmacodynamic, and pharmacokinetic pathways. Thus, it is necessary to comprehensively ascertain if the SNPs present in the aforementioned pathways are associated with interindividual differences in fentanyl requirement. In this study, we evaluated the association between 10 candidate SNPs in 9 genes and 24-hour postoperative fentanyl dose (primary outcome) and also with postoperative pain scores and time for first analgesia (secondary outcomes). ⋯ The SNP opioid receptor mu-1 ( OPRM1 ) (rs1799971) was associated with higher postoperative fentanyl requirement in South Indian patients undergoing major breast surgery. Twenty-four hour postoperative pain scores were higher in catechol-O-methyl transferase ( COMT ) (rs4680) carriers and lower in ATP binding cassette subfamily B member 1 ( ABCB1 ) (rs1045642) carriers, whereas time for first analgesic was lower in potassium channel subunit 1 ( KCNS1 ) (rs734784) carriers. However, these exploratory findings must be confirmed in a larger study.

Chronic pain is a major health problem given its high prevalence and its multiple consequences on the physical and psychological functioning of patients. It is therefore important to determine the relationship between these consequences and pain management strategies such as activity pacing. This review aimed to examine the association between activity pacing and the level of negative emotions in chronic pain. A second objective was to explore sex differences in this association. ⋯ Pacing is multidimensional and consists of various strategies of pain management which are not equally associated with negative emotions. It is important to use measures reflecting this conception to strengthen knowledges about the role of pacing in the development of negative emotions.

Long-Term Prognosis Following Early Rehabilitation in the ICU: A Retrospective Cohort Study.
Critically ill patients often have residual functional disabilities. Studies have shown that early rehabilitation improves short-term physical function. However, it remains unknown whether early rehabilitation affects long-term prognosis and healthcare resource utilization. ⋯ Starting rehabilitation within 3 days of ICU admission was associated with shorter durations of future hospitalization and lower healthcare costs. Early rehabilitation for ICU patients might be associated with reduced healthcare resource utilization.

Critical illness imposes a severe insult on the body, with various stressors triggering pronounced cell damage. This compromises cellular function, leading to a high risk of multiple organ failure. Autophagy can remove damaged molecules and organelles but appears insufficiently activated during critical illness. This review discusses insight into the role of autophagy in critical illness and the involvement of artificial feeding in insufficient autophagy activation in critical illness. ⋯ Insufficient autophagy during critical illness is at least partly explained by feeding-induced suppression. This may explain why early enhanced nutrition failed to benefit critically ill patients or even induced harm. Safe, specific activation of autophagy avoiding prolonged starvation opens perspectives for improving outcomes of critical illness.
