Abstract
BACKGROUND Propofol can increase neurotoxicity in infants but the precise mechanism is still unknown. Our previous study revealed that nuclear FMR1 interacting protein 1 (NUFIP1), a specific ribophagy receptor, can alleviate T cell apoptosis in sepsis. Yet, the effect of NUFIP1-engineered exosomes elicited from human umbilical cord blood mesenchymal stem cells (hUMSCs) on nerve injury induced by propofol remains unclear. This study intended to investigate the effect of NUFIP1-engineered exosomes on propofol-induced nerve damage in neonatal rats. METHODS Firstly, NUFIP1-engineered exosomes were extracted from hUMSCs serum and their identification was conducted using transmission electron microscopy (TEM), Flow NanoAnalyzer, quantitative real-time polymerase chain reaction (qRT-PCR), and western blot (WB). Subsequently, the optimal exposure duration and concentration of propofol induced apoptosis were determined in SH-SY5Y cell line using WB. Following this, we co-cultured the NUFIP1-engineered exosomes in the knockdown group (NUFIP1-KD) and overexpression group (NUFIP1-OE) with SH-SY5Y cells and assessed their effects on the apoptosis of SH-SY5Y cells using terminal-deoxynucleotidyl transferase mediated nick end labeling (TUNEL) assay, Hoechst 33258 staining, WB, and flow cytometry, respectively. Finally, NUFIP1-engineered exosomes were intraperitoneally injected into neonatal rats, and their effects on the learning and memory ability of neonatal rats were observed through the righting reflex and Morris water maze (MWM) test. Hippocampi were extracted from different groups for hematoxylin-eosin (HE) staining, immunohistochemistry, immunofluorescence, and WB to observe their effects on apoptosis in neonatal rats. RESULTS TEM, Flow NanoAnalyzer, qRT-PCR, and WB analyses confirmed that the exosomes extracted from hUMSCs serum exhibited the expected morphology, diameter, surface markers, and expression of target genes. This confirmed the successful construction of NUFIP1-KD and NUFIP1-OE-engineered exosomes. Optimal exposure duration and concentration of propofol were determined to be 24 hours and 100 µg/ml, respectively. Co-culture of NUFIP1 engineered exosomes and SH-SY5Y cells resulted in significant up-regulation of pro-apoptotic proteins Bax and c-Caspase-3 in the KD group, while anti-apoptotic protein Bcl-2 was significantly decreased. The OE group showed the opposite trend. TUNEL apoptosis assay, Hoechst 33258 staining, and flow cytometry yielded consistent results. Animal experiments demonstrated that intraperitoneal injection of NUFIP1-KD engineered exosomes prolonged the righting reflex recovery time of newborn rats, and MWM tests revealed a significant diminution in the time and number of newborn rats entering the platform. HE staining, immunohistochemistry, immunofluorescence, and WB results also indicated a significant enhancement in apoptosis in this group. Conversely, the experimental results of neonatal rats in the OE group revealed a certain degree of anti-apoptotic effect. CONCLUSIONS NUFIP1-engineered exosomes from hUMSCs have the potential to regulate nerve cell apoptosis and mitigate neurological injury induced by propofol in neonatal rats. Targeting NUFIP1 may hold great significance in ameliorating propofol-induced nerve injury.

Abstract
Every year millions of children are exposed to general anesthesia while undergoing surgical and diagnostic procedures. In the field of ophthalmology, 44,000 children are exposed to general anesthesia annually for strabismus surgery alone. While it is clear that general anesthesia is necessary for sedation and pain minimization during surgical procedures, the possibility of neurotoxic impairments from its exposure is of concern. In animals there is strong evidence linking early anesthesia exposure to abnormal neural development. but in humans the effects of anesthesia are debated. In humans many aspects of vision develop within the first year of life, making the visual system vulnerable to early adverse experiences and potentially vulnerable to early exposure to general anesthesia. We attempt to address whether the visual system is affected by early postnatal exposure to general anesthesia. We first summarize key mechanisms that could account for the neurotoxic effects of general anesthesia on the developing brain and review existing literature on the effects of early anesthesia exposure on the visual system in both animals and humans and on neurocognitive development in humans. Finally, we conclude by proposing future directions for research that could address unanswered questions regarding the impact of general anesthesia on visual development.

Frequencies, Modalities, Doses and Duration of Computerized Prescriptions for Sedative, Analgesic, Anesthetic and Paralytic Drugs in Neonates Requiring Intensive Care: A Prospective Pharmacoepidemiologic Cohort Study in 30 French NICUs From 2014 to 2020. Front Pharmacol 2022; 13:939869. [PMID: 35924063 PMCID: PMC9341520 DOI: 10.3389/fphar.2022.939869] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2022] [Accepted: 06/21/2022] [Indexed: 11/13/2022] Open
Abstract
Objectives: No consensus exists about the doses of analgesics, sedatives, anesthetics, and paralytics used in critically ill neonates. Large-scale, detailed pharmacoepidemiologic studies of prescription practices are a prerequisite to future research. This study aimed to describe the detailed prescriptions of these drug classes in neonates hospitalized in neonatal intensive care units (NICU) from computerized prescription records and to compare prescriptions by gestational age. Materials and Methods: We included all neonates requiring intensive care in 30 French level III units from 2014 through 2020 with a computerized prescription for an analgesic, sedative, anesthetic, or paralytic agent. We described frequencies of prescription, methods of administration, concomitant drug prescriptions, and dosing regimen, and compared them across gestational ages. Results: Among 65,555 neonates, 29,340 (44.8%) were prescribed at least one analgesic (acetaminophen in 37.2% and opioids in 17.8%), sedative (9.8%), anesthetic (8.5%), and/or paralytic agent (1%). Among preterm infants born before 28 weeks, 3,771/4,283 (88.0%) were prescribed at least one of these agents: 69.7% opioids, 41.2% sedatives, 32.5% anesthetics, and 5.8% paralytics. The most frequently prescribed agents were sufentanil (in 10.3% of neonates) and morphine (in 8.0% of neonates) for opioids, midazolam (9.3%) for sedatives, ketamine (5.7%) and propofol (3.3%) for anesthetics. In most neonates, opioids and sedatives were prescribed as continuous infusion, whereas anesthetics were prescribed as single doses. Opioids, sedatives and paralytics were mostly prescribed in association with another agent. Doses varied significantly by gestational age but within a limited range. Gestational age was inversely related to the frequency, cumulative dose and duration of prescriptions. For example, morphine prescriptions showed median (IQR) cumulative doses of 2601 (848–6750) vs. 934 (434–2679) µg/kg and median (IQR) durations of 7 (3–15) vs. 3 (2–5) days in infants born <28 vs. ≥ 37 weeks of gestation, respectively (p-value<0.001). Conclusion: The prescriptions of analgesic, sedative, anesthetic, or paralytic agent were frequent and often combined in the NICU. Lower gestational age was associated with higher frequencies, longer durations and higher cumulative doses of these prescriptions. Dose-finding studies to determine individualized dosing regimens and studies on long-term neurodevelopmental outcome according to received cumulative doses are required.

Premedication before laryngoscopy in neonates: Evidence-based statement from the French society of neonatology (SFN). Front Pediatr 2022; 10:1075184. [PMID: 36683794 PMCID: PMC9846576 DOI: 10.3389/fped.2022.1075184] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Accepted: 12/01/2022] [Indexed: 01/06/2023] Open
Abstract
CONTEXT Laryngoscopy is frequently required in neonatal intensive care. Awake laryngoscopy has deleterious effects but practice remains heterogeneous regarding premedication use. The goal of this statement was to provide evidence-based good practice guidance for clinicians regarding premedication before tracheal intubation, less invasive surfactant administration (LISA) and laryngeal mask insertion in neonates. METHODS A group of experts brought together by the French Society of Neonatology (SFN) addressed 4 fields related to premedication before upper airway access in neonates: (1) tracheal intubation; (2) less invasive surfactant administration; (3) laryngeal mask insertion; (4) use of atropine for the 3 previous procedures. Evidence was gathered and assessed on predefined questions related to these fields. Consensual statements were issued using the GRADE methodology. RESULTS Among the 15 formalized good practice statements, 2 were strong recommendations to do (Grade 1+) or not to do (Grade 1-), and 4 were discretionary recommendations to do (Grade 2+). For 9 good practice statements, the GRADE method could not be applied, resulting in an expert opinion. For tracheal intubation premedication was considered mandatory except for life-threatening situations (Grade 1+). Recommended premedications were a combination of opioid + muscle blocker (Grade 2+) or propofol in the absence of hemodynamic compromise or hypotension (Grade 2+) while the use of a sole opioid was discouraged (Grade 1-). Statements regarding other molecules before tracheal intubation were expert opinions. For LISA premedication was recommended (Grade 2+) with the use of propofol (Grade 2+). Statements regarding other molecules before LISA were expert opinions. For laryngeal mask insertion and atropine use, no specific data was found and expert opinions were provided. CONCLUSION This statement should help clinical decision regarding premedication before neonatal upper airway access and favor standardization of practices.
