Opioids in Post-stroke Pain: A Systematic Review and Meta-Analysis
Conclusions: The limited number of the included studies and their heterogeneity in terms of study design do not support the efficacy of opioids in post-stroke pain and in pain-related outcomes. Large double-blind randomized clinical trials with objective assessment of pain and related symptoms are needed to further investigate this topic.

Opioid antagonists as potential therapeutics for ischemic stroke
Publication date: Available online 6 August 2019Source: Progress in NeurobiologyAuthor(s): Nadia Peyravian, Emre Dikici, Sapna Deo, Michal Toborek, Sylvia DaunertAbstractChronic use of prescription opioids can exacerbate risk and severity of ischemic stroke. Annually, 6 million people die from stroke worldwide and there are no neuroprotective or neurorestorative agents to improve stroke outcomes and promote recovery. Prescribed opioids such as morphine have been shown to alter tight junction protein expression, resulting in the disruption of the blood brain barrier (BBB), ultimately leading to stroke pathogenesis. Conseque...

Increase of Cry 1 expression is a common phenomenon of the disturbed circadian clock in ischemic stroke and opioid addiction
Biochem Biophys Res Commun. 2021 Apr 21;558:8-13. doi: 10.1016/j.bbrc.2021.04.053. Online ahead of print.ABSTRACTIncreasing evidences suggest the involvement of disrupted circadian clock in various pathologies including stroke and substance abuse. Here we took an attempt to do a comparative study on the regulation of circadian clock gene expression under two pathological circumstances - Opioid addiction and Ischemic stroke in the same cell line model (human neuroblastoma SH-SY5Y cells). To mimic in vivo ischemic stroke condition cells were placed in a hypoxia chamber and incubated for 10 h in balanced salt solution lacking...

S1-1. Spinal cord stimulation for post-stroke pain
Spinal cord stimulation (SCS) is used to treat for several types of intractable pain syndromes, but it is not commonly used for treating post-stroke pain. Therefore, in this study, we analyzed the effects of SCS in patients with post-stroke pain. Neurological imaging and pharmacological analysis using thiopental, ketamine and morphine tests were conducted for 30 patients with post-stroke pain. For all patients, percutaneous electrodes were inserted under local anesthesia, and trial stimulation was performed for 5–7days. If the patient experienced pain relief during the trial stimulation, a pulse generator was implanted. ...

Robert E. Lee's Last Stand: His Dying Words and the Stroke That Killed Him. (P1.294)
CONCLUSIONS: Lee suffered chronic angina and congestive heart failure, with a probable myocardial infarction during the war. His death stemmed from an acute, possibly cardioembolic stroke manifesting as expressive aphasia, and subsequent respiratory complications. Given his aphasia, Lee’s famous last words are questionable.Disclosure: Dr. Southerland has received personal compensation in an editorial capacity for Neurology Podcast.

Effects of thalamic hemorrhagic lesions on explicit and implicit learning during the acquisition and retrieval phases in an animal model of central post-stroke pain.
Abstract Hemorrhagic stroke has many symptoms, including central pain, learning and memory impairments, motor deficits, language problems, emotional disturbances, and social maladjustment. Lesions of the ventral basal complex (VBC) of the thalamus elicit thermal and mechanical hyperalgesia, forming an animal model of central post-stroke pain (CPSP). However, no research has yet examined the involvement of learning and memory in CPSP using an animal model. The present study examined whether VBC lesions affect motor function, conditioned place preference (CPP; implicit memory), and spatial learning (explicit memory)...

Focal Anticoagulation by Somatic Gene Transfer: Towards Preventing Cardioembolic Stroke
Cardioembolic stroke (CS) has emerged as a leading cause of ischaemic stroke (IS); distinguished by thrombi embolising to the brain from cardiac origins; most often from the left atrial appendage (LAA). Contemporary therapeutic options are largely dependent on systemic anticoagulation as a blanket preventative strategy, yet this does not represent a nuanced or personalised solution. Contraindications to systemic anticoagulation create significant unmedicated and high-risk cohorts, leaving these patients at risk of significant morbidity and mortality.

The Effect of Intraoperative Fluid Management According to Stroke Volume Variation on Postoperative Bowel Function Recovery in Colorectal Cancer Surgery
J Clin Med. 2021 Apr 25;10(9):1857. doi: 10.3390/jcm10091857.ABSTRACTStroke volume variation (SVV) has been used to predict fluid responsiveness; however, it remains unclear whether goal-directed fluid therapy using SVV contributes to bowel function recovery in abdominal surgery. This prospective randomized controlled trial aimed to compare bowel movement recovery in patients undergoing colon resection surgery between groups using traditional or SVV-based methods for intravenous fluid management. We collected data between March 2015 and July 2017. Bowel function recovery was analyzed based on the gas-passing time, sips of ...

Mast Cells Contribute to Brain Microvascular Permeability in Sickle Cell Disease
We examined the ability of mast cells to stimulate P-selectin expression and BBB permeability via ER stress in a sickle microenvironment.We isolated MCs from HbAA-BERK and HbSS-BERK, control and sickle mice, respectively; incubated them in vitro and collected mast cell conditioned media (MCCM) from HbAA MCs and HbSS MCs. Normal mouse brain microvascular endothelial cells (mBMECs) were treated with unconditioned MCCM, HbAA MCCM, or HbSS MCCM to examine the effect of mast cell activation on endothelium. We observed increased mast cell activity in HbSS mice evinced by significantlyhigher plasma and skin histamine levels, comp...

A lot of drugs and not much oxygen: Is the cocktail responsible for delirium?
We read with great interest the article by Arenson and colleagues that analyzed the risk factors for postoperative delirium, with particular reference to the influence of intensive care unit environment, in a large study population undergoing cardiac surgery. In their multivariate analysis, postoperative delirium was significantly associated with preoperative (eg, age, preadmission use of benzodiazepine), intraoperative (eg, combined coronary artery bypass grafting and valve surgery), and postoperative (eg, stroke or transient ischemic attack, mechanical ventilation>24 hours, blood transfusion, postoperative renal insuffic...

Guideline of neuropathic pain treatment and dilemma from neurological point of view.
Authors: Yang CM, Chen NC, Shen HC, Chou CH, Yeh PS, Lin HJ, Chang CY, Cheng TJ, Lin KC Abstract Neuropathic pain is a complicated symptomatic disease as migraine in recent years. Not because the pain character differed from the nociceptive inflammatory symptoms but because of its complexity of mechanisms. Though peripheral sensitization, ectopic discharge, central sensitization, central re-organization and loss of inhibition play part of roles in mechanisms, however, based on this mechanistic treatment, the outcome still disappointed physicians and patients, exampled as central post-stroke central pain (CPSP). The...

Effects of Adjuvant Analgesics on Cerebral Ischemia-Induced Mechanical Allodynia.
Abstract Central post-stroke pain (CPSP), a potential sequela of stroke, is classified as neuropathic pain. Although we recently established a CPSP-like model in mice, the effects of adjuvant analgesics as therapeutic drugs for neuropathic pain in this model are unknown. Hence, the aim of the present study was to assess the usefulness of our model by evaluating the effects of adjuvant analgesics used for treating neuropathic pain in this mouse model of CPSP. Male ddY mice were subjected to 30 min of bilateral carotid artery occlusion (BCAO). The development of hind paw mechanical allodynia was measured after BCA...
