Prehospital triage for endovascular clot removal in acute stroke patients.

Aim: To establish prehospital triage in accordance with the new guidelines for endovascular therapy, we retrospectively analyzed the monitoring data of the city-wide transportation system using the Maria Prehospital Stroke Scale (MPSS), a novel prehospital stroke scale for emergency medical technicians (EMTs) to predict the likelihood of thrombolytic therapy after transportation.

Methods: Kawasaki City, Japan, has six comprehensive stroke centers (CSCs) and six primary stroke centers (PSCs). In CSCs, endovascular therapy can be carried out 24 h a day, 7 days a week, but not in PSCs.

Quality assurance monitoring of a citywide transportation protocol improves clinical indicators of intravenous tissue plasminogen activator therapy: a community-based, longitudinal study.

Background: Stroke-bypass transportation to the stroke center by paramedics is important to maximize the efficiency of intravenous tissue plasminogen activator (iv-tPA) therapy. To improve access to stroke thrombolysis, a citywide protocol was launched on January 2007 in Kawasaki City (population 1.4 million) using the Maria Prehospital Stroke Scale (MPSS), and quality assurance monitoring has been performed every 6 months.

Prediction of thrombolytic therapy after stroke-bypass transportation: the Maria Prehospital Stroke Scale score.

There is no prehospital stratification tool specifically for predicting thrombolytic therapy after transportation. We developed a new prehospital scale named the Maria Prehospital Stroke Scale (MPSS) by modifying the Cincinnati Prehospital Stroke Scale. Our objective is to evaluate its utility in a citywide bypass transportation protocol for intravenous (IV) tissue plasminogen activator (tPA).

We previously reported that chronic pain induced anxiety with changes in opioidergic function in the central nervous system.

LPT1 encodes a membrane-bound O-acyltransferase involved in the acylation of lysophospholipids in the yeast Saccharomyces cerevisiae.

Phospholipids are major components of cellular membranes that participate in a range of cellular processes. Phosphatidic acid (PA) is a key molecule in the phospholipid biosynthetic pathway. In Saccharomyces cerevisiae, SLC1 has been identified as the gene encoding lysophosphatidic acid acyltransferase, which catalyzes PA synthesis.

Chronic pain-induced astrocyte activation in the cingulate cortex with no change in neural or glial differentiation from neural stem cells in mice.

Pain pathways terminate in discrete brain areas that monitor the sensory and affective qualities of the initiating stimulus and show remarkable plasticity. Here, we found that chronic pain by sciatic nerve ligation caused a dramatic increase in glial fibrillary acidic protein (GFAP)-like immunoreactivity (IR), which is located in the dendritic astrocytes, with its expanding distribution in the cingulate cortex (CG) of mice. The branched GFAP-like IR in the CG of nerve-ligated mice was overlapped with S100beta-like IR, which is highly limited to the cell body of astrocytes, whereas there was no difference of S100beta-like IR between sham-operated and nerve-ligated mice.

Differences in tolerance to anti-hyperalgesic effects between chronic treatment with morphine and fentanyl under a state of pain.

The present study was undertaken to investigate the possible change in anti-hyperalgesic effect following repeated treatment with morphine or fentanyl using the dose to improve the thermal hyperalgesia under an inflammatory pain-like state. The anti-hyperalgesic effect induced by fentanyl in complete Freund's adjuvant (CFA)-pretreated mice rapidly disappeared during the consecutive administration of fentanyl, whereas morphine preserved its potency of anti-hyperalgesic effect. In addition, repeated treatment with fentanyl, but not morphine, resulted in the increase in levels of phosphorylated-mciro-opioid receptor (MOR) associated with the enhanced inactivation of protein phosphatase 2A and the reduction in Rab4-dependent MOR resensitization.
