Effect of total intravenous-based immediate extubation on patient outcomes in adult liver transplantation: A retrospective cohort study.

Background: Although step-down emergence and extubation are universally practiced after liver transplantation (LT), prolonged mechanical ventilation and positive end-expiratory pressure may enhance predisposition to ventilator-associated complications and may be associated with inferior outcomes.

Methods: We screened 339 patients who underwent LT in this retrospective cohort study. After propensity score matching, 35 patients in Group F (total intravenous-based immediate extubation, TIIE) and 107 patients in Group C (balanced anesthesia with step-down extubation) with balanced and comparable pre- and intraoperative profiles were selected for analysis.

Surgery-induced neuroinflammatory transcriptional programs in medial prefrontal cortex of mice during early phase of perioperative neurocognitive disorders.

Patients receiving anesthesia and surgery may experience cognitive dysfunction, memory deficits, and mental disturbances, which are referred to as perioperative neurocognitive disorders (PND). The function of the medial prefrontal cortex (mPFC) is disrupted during early phase of PND. To gain insight into the mechanisms of PND, we collected mouse mPFC tissues 6 h post-surgery and performed RNA sequencing analysis.

Chemokines and chemokine receptors: Potential therapeutic targets in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease that affects connective tissue and can lead to multisystem organ damage. Chemokines are a class of small proteins that interact with receptors and participate in a variety of physiological functions, including cell growth, differentiation, apoptosis and distribution. They also play important roles in pathological processes, such as the inflammatory response, wound repair, tumor formation and metastasis.

Electroacupuncture attenuates neuropathic pain via suppressing BIP-IRE-1α-mediated endoplasmic reticulum stress in the anterior cingulate cortex.

Studies have suggested that endoplasmic reticulum stress (ERS) is involved in neurological dysfunction and that electroacupuncture (EA) attenuates neuropathic pain (NP) via undefined pathways. However, the role of ERS in the anterior cingulate cortex (ACC) in NP and the effect of EA on ERS in the ACC have not yet been investigated. In this study, an NP model was established by chronic constriction injury (CCI) of the left sciatic nerve in rats, and mechanical and cold tests were used to evaluate behavioral hyperalgesia.

Spinal TAOK2 contributes to neuropathic pain via cGAS-STING activation in rats.

Thousand and one amino acid kinase 2 (TAOK2) is a member of the mammalian sterile 20 kinase family and is implicated in neurodevelopmental disorders; however, its role in neuropathic pain remains unknown. Here, we found that TAOK2 was enriched and activated after chronic constriction injury (CCI) in the rat spinal dorsal horn. Meanwhile, cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS)-stimulator of interferon genes (STING) signaling was also activated with hyperalgesia.

Thoracic endovascular aortic repair of an anastomosis pseudoaneurysm after the Bentall procedure assisted by rapid ventricular pacing: A case report.

Background: Although commonly used for the treatment of descending aortic dissection, endovascular repair is challenging for ascending aortic pseudoaneurysms. Rapid ventricular pacing (RVP), a method that temporarily impedes cardiac output by stopping ventricular activity, heralds potential benefits for thoracic endovascular aortic repair (TEVAR) during precision landing. Recently, we successfully treated an anastomosis pseudoaneurysm after the Bentall procedure using TEVAR assisted by RVP.

The efficacy and safety of remifentanil patient-controlled versus epidural analgesia in labor: A meta-analysis and systematic review.

Background: Remifentanil patient-controlled analgesia (rPCA) and epidural analgesia (EA) has been used for pain relief in labor. We aimed to evaluate the efficacy and safety of rPCA versus EA in labor, to provide evidence support for clinical analgesia and pain care.

Methods: We searched PubMed, EMBASE, ScienceDirect, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang and Weipu databases for RCTs comparing rPCA and EA in labor until February 15, 2022.

PSD-95 in the anterior cingulate cortex contributes to neuropathic pain by interdependent activation with NR2B.

Studies suggest that the scaffolding protein, postsynaptic density protein-95 (PSD-95), is involved in multiple neurological dysfunctions. However, the role of PSD-95 in the anterior cingulate cortex (ACC) in neuropathic pain (NP) has not been investigated. The current study addressed the role of PSD-95 in the ACC in NP and its modulating profile with NMDA receptor subunit 2B (NR2B).

Anesthesia management of combined sequential heart-liver transplantation using a caval clamp without venovenous bypass: A case report.

Familial amyloid polyneuropathy, an autosomal-dominant disease due to mutations in the transthyretin gene, often affects the heart and liver, and is treated best with a combined heart-liver transplantation (CHLT). Although it remains an uncommonly performed procedure, the number of patients undergoing CHLT is increasing. Because of the complexity associated with dual pathophysiology, CHLT poses an extraordinary challenge for anesthesia management.

Circulation collapse caused by intracardiac thrombosis associated with tranexamic acid administration: A case report.

Rationale: Perioperative administration of tranexamic acid has been suggested to reduce bleeding and blood transfusion requirements in patients undergoing orthopedic surgery. Despite being sporadic, the potential risk for thrombotic complications cannot be ignored. However, intracardiac thrombosis associated with tranexamic acid administration is rare.

Anesthetic management of lung transplantation in a patient with end-stage COVID-19 pneumonia: A case report.

Rationale: The COVID-19 pandemic is spreading around the world and the leading cause of death is rapidly progressive respiratory failure because of lung damage and consolidation. Lung transplantation is the last line of treatment for chronic end-stage lung diseases. There were several cases of lung transplantation reported in patients with COVID-19 pneumonia.

Effect of ultrasound-guided transversus abdominis plane block with rectus sheath block on patients undergoing laparoscopy-assisted radical resection of rectal cancer: a randomized, double-blind, placebo-controlled trial.

Background: Many patients complain of pain following laparoscopic surgery. Clinicians have used ultrasound-guided posterior transversus abdominis plane block (TAPB) and rectus sheath block (RSB) for multimodal analgesia after surgery. We investigated the analgesic effects of US-guided posterior TAPB with RSB on postoperative pain following laparoscopy-assisted radical resection of early-stage rectal cancer.

CXCR3 contributes to neuropathic pain via ERK activation in the anterior cingulate cortex.

The anterior cingulate cortex (ACC) is activated by noxious stimuli and is involved in the affective component of pain processing; but its role in the sensory component of pain remains largely unknown. Studies have verified that Chemokine (C-X-C motif) receptor 3 (CXCR3) is involved in nociceptive sensitization in the spinal cord after peripheral nerve injury; however, the expression of CXCR3 in the ACC and its role in neuropathic pain has not been reported. Here, we showed that CXCR3 co-localized with neurons in the ACC and the upregulation of CXCR3 corresponded with hypersensitive behaviors after a chronic constriction injury of the sciatic nerve.

[Anesthesia management in cesarean section for patient with COVID-19: a case report].

Since the coronavirus disease 2019 (COVID-19) affects the cardio-pulmonary function of pregnant women, the anesthetic management and protection of medical staff in the cesarean section is significantly different from that in ordinary surgical operation. This paper reports a case of cesarean section for a woman with COVID-19, which was successfully performed in the First Affiliated Hospital of Zhejiang University School of Medicine on February 8, 2020. Anesthetic management, protection of medical staff and psychological intervention for the pregnant woman during the operation were discussed.

C-X-C Motif Chemokine 10 Contributes to the Development of Neuropathic Pain by Increasing the Permeability of the Blood-Spinal Cord Barrier.

Neuropathic pain is among the most debilitating forms of chronic pain. Studies have suggested that chronic pain pathogenesis involves neuroimmune interactions and blood-spinal cord barrier (BSCB) disruption. However, the underlying mechanisms are poorly understood.

Resection of the gastric submucosal tumor (G-SMT) originating from the muscularis propria layer: comparison of efficacy, patients' tolerability, and clinical outcomes between endoscopic full-thickness resection and surgical resection.

Background And Aims: Endoscopic full-thickness resection (EFTR) has been increasingly applied in the treatment of gastric submucosal tumors (G-SMTs) with explorative intention. This study aimed to compare the efficacy, tolerability, and clinical outcomes of EFTR and surgical intervention for the management of muscularis propria (MP)-derived G-SMTs.

Methods: Between September 2011 and May 2019, the clinical records of patients with MP-derived G-SMTs undergoing EFTR at our endoscopic unit were collected.

Epidural anesthesia for emergency cesarean section in a woman with Fontan circulation: A case report.

Rationale: Anesthetic management of pregnant women with Fontan circulation remains challenging. There are few reports that describe the anesthetic management of cesarean section after Fontan surgery. Here, we present a case of successful epidural anesthesia in a woman with Fontan circulation who required emergency cesarean section.

Intra-amygdala infusion of zeta inhibitory peptide attenuates neuropathic pain but not inflammatory pain in adult rats.

Background: Protein kinase Mζ (PKMζ), a typical brain-specific PKC isoform, has been shown to be critical in the maintenance of long-term potentiation and memory storage. Zeta inhibitory peptide (ZIP), a peptide with selective inhibition of PKMζ, has been used in relieving experimental neuropathic pain and disrupting memory. The aim of this study was to investigate the effects of intra-amygdalar infusion of ZIP on neuropathic pain induced by chronic constriction injury (CCI), and inflammatory pain induced by complete Freund's adjuvant (CFA) in adult rats.

Function and mechanism of pyrin and IL-10 in the regulation of the inflammasome in pulmonary vascular endothelial cells following hemorrhagic shock.

The present study aimed to evaluate the function of pyrin and interleukin-10 (IL-10) and the potential mechanisms underlying the regulation of inflammation in pulmonary vascular endothelial cells (ECs) following hemorrhagic shock (HS). Adult female Sprague-Dawley rats were divided into 4 groups (n=6 in each group) to examine the changes in pyrin expression following HS-lipopolysaccharide (LPS) administration, including the following groups: A sham operation (SM) + tracheal injection of saline (SAL) group; a HS + SAL group; a SM + LPS group (with a tracheal injection of endotoxin); and a HS + LPS group. An additional 4 groups were used to evaluate the function of IL-10, by the additional intratracheal injection of recombinant IL-10.

Mast cell stabilizer ketotifen reduces hyperalgesia in a rodent model of surgically induced endometriosis.

This study aimed to investigate the effect of oral treatment with ketotifen, a mast cell (MC) stabilizer, in a rat model of surgically induced endometriosis. At 14 days after Sprague-Dawley rats had surgery, they were treated with ketotifen (1 or 10 mg/kg/day). Pain behaviors were evaluated 3 days prior to surgery and then at 7, 14, 21, and 28 days after surgery.

Pulsed radiofrequency to the dorsal root ganglion or the sciatic nerve reduces neuropathic pain behavior, decreases peripheral pro-inflammatory cytokines and spinal β-catenin in chronic constriction injury rats.

Background And Objectives: Pulsed radiofrequency (PRF) is a minimal neurodestructive interventional pain therapy. However, its analgesic mechanism remains largely unclear. We aimed to investigate the peripheral and spinal mechanisms of PRF applied either adjacent to the ipsilateral L5 dorsal root ganglion (PRF-DRG) or PRF to the sciatic nerve (PRF-SN) in the neuropathic pain behavior induced by chronic constriction injury (CCI) in rats.

Silencing of spinal Trpv1 attenuates neuropathic pain in rats by inhibiting CAMKII expression and ERK2 phosphorylation.

Accumulating evidence suggests a potential role of transient receptor potential vanilloid 1 (TRPV1) channels in inflammatory and cancer-related pain. However, the role of TRPV1 in the maintenance of neuropathic pain remains elusive. The current study investigated the effects of transient Trpv1 gene silencing using a small interference RNA (siRNA) on neuropathic pain induced by chronic constriction injury (CCI) of the sciatic nerve in rats.

Immediate extubation after heart transplantation in a child by remifentanil-based ultra-fast anesthesia: A case report.

Rationale: Ventilator-associated complications comprise important fatal aetiologies during heart transplantation. Ultra-fast anesthesia might provide the most effective measure to prevent this type of complication. Immediate extubation after heart transplantation (IEAHT) has recently been reported in adult patients.
