Association of Intensive Morphine Treatment and Increased Stroke Incidence in Prostate Cancer Patients: A Population-based Nested Case-Control Study
Conclusions
Intense morphine treatment may be associated with an increased stroke incidence in patients with malignancy, and the association is particularly significant for prostate cancer patients.

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.

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. ...

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)...

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...

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...

The safety of morphine use in acute coronary syndrome: a meta-analysis
Conclusion
The use of morphine for pain control in ACS was associated with an increased risk of in-hospital recurrent MI. Randomised clinical trials are needed to further investigate the safety of morphine in ACS.

0209: Long-term clinical impact of pre-hospital morphine use in ST-elevation myocardial infarction patients. FAST-MI 2010 registry
Conclusion Pre-hospital morphine use was not associated with an increase of in-hospital complication and one-year mortality; and, could be more used as recommended in the current guidelines.

Highlights from the literature
Morphine and the baby brain Morphine gets used a lot in neonatal care, especially as we now understand the need to give appropriate analgesia and sedation to babies receiving intensive care. Yet there has always been a nagging concern that though we do the right thing in early life, we may be creating difficulties for these babies in later childhood. We should take some reassurance about this from a paper by Steinhorn (J Pediatr 2015;166:1200–7) in which 230 babies, all under 30 weeks at birth and a quarter of whom received morphine, were followed up at 2 and 7 years. At 2 years the morphine exposed babies demonstrat...

Risk of type 2 diabetes mellitus in female breast cancer patients treated with morphine: a retrospective population-based time-dependent cohort study
A key element of the palliative care of cancer patients is the management of chronic pain [1]. Opioids continue to be a mainstay in the management of cancer pain in all treatment guidelines [2], and morphine is regarded as the “gold standard” [3–6]. Considered as broad-spectrum analgesics, opioids have multiple side effects and potential complications [7]. Our previous studies indicated that morphine treatment is associated with subdural hemorrhage [8], pulmonary embolism [9], and acute coronary syndrome [10] in cancer patients, as well as increased stroke incidence in prostate cancer patients [11].
