Conveniently-Grasped Field Assessment Stroke Triage (CG-FAST): A Modified Scale to Detect Large Vessel Occlusion Stroke
Conclusions: CG-FAST scale could be an effective and simple scale for accurate identification of LVOS among AIS patients. Introduction Large vessel occlusion stroke (LVOS) often leads to severe disability and mortality. Although endovascular therapy (EVT) has been proved to be effective for LVOS patients (1–9), especially in anterior circulation, its benefit is highly time-dependent (10, 11). As hospitals with around-the-clock endovascular capability are scarce in many parts of the world and patients admitted directly to a CSC would have better outcomes than those receiving drip and ship treatment (12, 13), t...

Lacunar stroke as a very late complication of radiotherapy: value of nuclear medicine techniques.
CONCLUSIONS: The reappearance of neurological symptoms years after radiotherapy of a brain neoplasm poses a diagnostic dilemma. Current diagnostic techniques are very accurate but present false positives. The various nuclear medicine techniques, in particular PET-CT 11C-methionine, are a diagnostic aid. With the presentation of this case we intend to draw attention to one of the late complications of radiation therapy and the various differential diagnoses. Diagnostic and therapeutic advances have increased the life expectancy of cancer patients, so these late complications are expected to be more frequent. PMID: 3331...

Chronic cerebral hypoperfusion and blood-brain barrier disruption in uninjured brain areas of rhesus monkeys subjected to transient ischemic stroke
J Cereb Blood Flow Metab. 2022 Feb 9:271678X221078065. doi: 10.1177/0271678X221078065. Online ahead of print.ABSTRACTBlood-brain barrier (BBB) disruption is a pivotal pathophysiological process in ischemic stroke. Although temporal changes in BBB permeability during the acute phase have been widely studied, little is known about the chronic phase of cerebrovascular changes that may have a large impact on the long-term outcome. Therefore, this study was aimed to measure cerebral vascular abnormalities using CT perfusion in nine rhesus monkeys subjected to transient middle cerebral artery occlusion (tMCAO) for ≥1 year (MCA...

A Serious Diagnosis Lacking Common Symptoms
​BY JENNIFER TUONG; IVAN KHARCHENKO; JEAN LUC AGARD; & AHMED RAZIUDDIN, MDA 65-year-old man who had HIV well-controlled with highly active antiretroviral therapy, hypertension, sciatica, and restless leg syndrome presented to the emergency department with left leg pain. He also had had chemotherapy and radiation for anal cancer. The patient said the pain had started 45 minutes earlier when he was sitting on the toilet.He described the pain as sore in quality and 10/10 on the pain scale. He reported that it had started in his lower back and radiated to his left leg. He said he had had no trauma or weakness to the regi...

Very late complications of oncotherapy in glioblastoma patients: A case series.
CONCLUSION: All stroke-like syndromes are diagnoses of exclusion. To avoid misinterpretation of imaging findings as glioblastoma recurrence and avert recall oncotherapy or redundant interventions, better understanding of delayed complications of brain tumor therapy is crucial.

Methods of Preventing Tissue Ischemia
Nitric oxide (NO) plays an important role as a major intrinsic vasodilator, and increases blood flow to tissues and organs. Disruption of this process leads to peripheral vascular disease, ischemic heart disease, stroke, diabetes, and many more significant diseases. Researchers at the NIH have discovered that the matrix protein thrombospondin-1 blocks the beneficial effects of NO, and prevents it from dilating blood vessels and increasing blood flow to organs and tissues. Additionally, the inventors discovered that this regulation requires interaction with thrombospondin-1's cell receptor CD47. Murine studies revealed that...

The emerging role of galectins in cardiovascular disease.
Abstract Galectins are an ancient family of β-galactoside-specific lectins and consist of 15 different types, each with a specific function. They play a role in the immune system, inflammation, wound healing and carcinogenesis. In particular the role of galectin in cancer is widely studied. Lately, the role of galectins in the development of cardiovascular disease has gained attention. Worldwide cardiovascular disease is still the leading cause of death. In ischemic heart disease, atherosclerosis limits adequate blood flow. Angiogenesis and arteriogenesis are highly important mechanisms relieving ischemia by rest...

Severe Symptoms, but a Truly Treatable Disease
​BY NOURA MAHDI; DARRON LEWIS; JEREMY OSBORNE; & AHMED RAZIUDDIN, MDA 73-year-old man was brought to the emergency department from his nursing home for rectal bleeding and anemia. The patient mentioned he had had episodes of bright red rectal bleeding and constipation for a few months. A colonoscopy had been done prior to the visit, which revealed a large intestine tumor and biopsy confirming adenocarcinoma. He was awaiting an appointment with his surgeon.The patient reported bloody rectal leakage, and a CBC done at the nursing home showed a hemoglobin level of 7.2. He also complained of dyspnea but denied any other ...

Cardiovascular Programming During and After Diabetic Pregnancy: Role of Placental Dysfunction and IUGR
This study demonstrated that the incidence of ischemic heart disease and death were three times higher among men with low birth weight compared to men with high birth weight (5). Epidemiological investigations of adults born at the time of the Dutch famine between 1944 and 1945 revealed an association between maternal starvation and a low infant birth weight with a high incidence of hypertension and coronary heart disease in these adults (23). Furthermore, Painter et al. reported the incidence of early onset coronary heart disease among persons conceived during the Dutch famine (24). In that regard, Barker's findin...

Abstract 4058: Acid-sensing ion channel 1a (ASIC1a) contributes to cell proliferation and migration caused by acidic environment in human glioma cells
Conclusions: Extracellular acid reduces proliferation and migration in glioma cells. Extracellular acid induces death of glioma cells via ASIC1a mechanisms. These results indicate the presence of ASIC1a in glioma cells and may play significant role in glioma progression.
