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.

Observation of hemodynamic parameters using a non-invasive cardiac output monitor system to identify predictive indicators for post-spinal anesthesia hypotension in parturients undergoing cesarean section.
In conclusion, the baseline CI obtained via the bioreactance-based NICOM™ system may serve as a predictor of post-spinal anesthesia hypotension in parturients regardless of patient position. PMID: 33093906 [PubMed]

Daily intermittent fasting in mice enhances morphine-induced antinociception while mitigating reward, tolerance, and constipation
The opioid epidemic has plagued the United States with high levels of abuse and poor quality of life for chronic pain patients requiring continuous use of opioids. New drug discovery efforts have been implemented to mitigate this epidemic; however, new medications are still limited by low efficacy and/or high side effect and abuse potential. Intermittent fasting (IF) has recently been shown to improve a variety of pathological states, including stroke and neuroinflammation. Numerous animal and human studies have shown the benefits of IF in these disease states, but not in pain and opioid treatment. We thus subjected male a...

Lysophosphatidic Acid Receptor Signaling Underlying Chronic Pain and Neuroprotective Mechanisms through Prothymosin α.
Abstract For my Ph.D. research topic, I isolated endogenous morphine-like analgesic dipeptide, kyotorphin, which mediates Met-enkephalin release, and discovered kyotorphin synthetase, a putative receptor and antagonist. Furthermore, I succeeded in purifying μ-opioid receptor and functional reconstitution with purified G proteins. After receiving my full professor position at Nagasaki University in 1996, I worked on two topics of research, molecular mechanisms of chronic pain through lysophosphatidic acid (LPA) and identification and characterization of neuroprotective protein, prothymosin α. In a series of studi...

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...

Challenge to the Intestinal Mucosa During Sepsis
Conclusion The impact of sepsis on the gut is manifold, e.g., sepsis mediated alteration of the gut-blood barrier and increase in the intestinal permeability, which may correlate with the phenomena of bacterial translocation and lymphatic activation (“toxic-lymph”). Systemic consequences of sepsis are widespread and concern to the coagulative system, the microbiome as well as enzymes, such as pancreatic proteases, MMPs and IAPs. Nevertheless, the therapeutic approaches for modulating the mucosal immune system are still rarely effective in daily routine. Recent published studies showing that treatment with ...

Connecting Metainflammation and Neuroinflammation Through the PTN-MK-RPTP β/ζ Axis: Relevance in Therapeutic Development
Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroi...

Effect of morphine use on oral P2Y12 platelet inhibitors in acute myocardial infarction: Meta-analysis
ConclusionCo-administration of morphine with P2Y12 inhibitors possibly decreases their efficacy in platelet inhibition. However, this did not translate into higher adverse outcomes due to low event rates, inadequate for analysis. A large randomized study is needed to evaluate the narcotic-P2Y12 interaction.

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.

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...

My debilitating endometriosis symptoms – Kate ’ s story
Hi, I’m Kate, 39, married with no children. I had always suffered from heavy and painful periods but this had mostly been managed by taking the combined pill. My periods remained heavy and I suffered from some flooding but this was manageable with planning! Approximately 7 years ago my periods became worse and I started to experience more symptoms such as regular and frequent abdominal pain, random bleeding, bloating, very painful intercourse and things just didn’t feel right. Anyway, I went to the Dr’s who straight away suggested that it sounded like I had endometriosis and referred me to a consultant. A...
