MRI for all: Cheap portable scanners aim to revolutionize medical imaging
.news-article__hero--featured .parallax__element{ object-position: 47% 50%; -o-object-position: 47% 50%; } The patient, a man in his 70s with a shock of silver hair, lies in the neuro intensive care unit (neuro ICU) at Yale New Haven Hospital. Looking at him, you’d never know that a few days earlier a tumor was removed from his pituitary gland. The operation didn’t leave a mark because, as is standard, surgeons reached the tumor through his nose. He chats cheerfully with a pair of research associates who have come to check his progress with a new and potentially revolutionary device they are testing. The cylind...

Acute Stroke Diagnosis
Am Fam Physician. 2022 Jun 1;105(6):616-624.ABSTRACTStroke accounts for significant morbidity and mortality and is the fifth leading cause of death in the United States, with direct and indirect costs of more than $100 billion annually. Expedient recognition of acute neurologic deficits with appropriate history, physical examination, and glucose testing will help diagnose stroke and rule out mimicking presentations. The National Institutes of Health Stroke Scale should be used to determine stroke severity and to monitor for evolving changes in clinical presentation. Initial neuroimaging is used to differentiate between isc...

Pregnancy-Related Stroke: A Review
Conclusions and Relevance Early recognition and management are integral in decreasing the morbidity and mortality associated with a stroke in pregnancy. Relevance Statement This study was an evidence-based review of stroke in pregnancy and how to diagnose and mange a pregnancy complicated by a stroke. Target Audience Obstetricians and gynecologist, family physicians Learning Objectives After completing this learning activity, the participant should be better able to identify the pregnancy-related risk factors for a stroke; explain the presenting signs and symptoms of a stroke in pregnancy; describe...

Significance of concurrent ipsilateral intracranial carotid artery stenosis in carotid revascularization
A 71-year-old male presenting with a transient ischemic attack was found to have an ipsilateral severe proximal right internal carotid artery (ICA) stenosis as graded per the North American Symptomatic Carotid Endarterectomy Trial (NASCET) criteria. He was subsequently treated with right internal carotid endarterectomy (CEA). The surgery was complicated by a right sided watershed infarction determined by magnetic resonance imaging (MRI) of the head. His post-surgery National Institutes of Health Stroke Scale score was 6 and the 90  days modified Rankin Scale score was 3.

Polyoxometalate nanoclusters act as broad-spectrum antioxidants to alleviate ischemic stroke by intrathecal injection
Conclusion: Intrathecal injection significantly improved the delivery and efficacy of POM nanoclusters to the brain, resulting in the rapid accumulation of POM nanoclusters in the ischemic penumbra. Due to this, we confirmed that the POM nanoclusters could be used as nano-antioxidants to inhibit oxidative stress as well as inflammatory damage effectively.

Sex Differences in Sex Hormone Profiles and Prediction of Consciousness Recovery After Severe Traumatic Brain Injury
Conclusion: These findings indicate that TBI differentially affects the levels of sex-steroid hormones in men and women patients. Plasma levels of testosterone could be a good candidate blood marker to predict recovery from unconsciousness after sTBI for male patients. Introduction Traumatic brain injury (TBI) is a major cause of death and disability worldwide and is increasing in incidence (1). Patients with acute severe TBI (sTBI) often develop severe disorders of consciousness, i.e., coma, minimally conscious state or vegetative state. Although many patients may regain consciousness during the 1-month post-TBI p...

Decreased CSF Levels of ß-Amyloid in Patients With Cortical Superficial Siderosis
Conclusions: Our results demonstrate that the presence and extent of cSS are associated with reduced CSF ß-amyloid 42 levels. Further studies are needed to investigate the underlying mechanisms of this association. Introduction Cerebral amyloid angiopathy (CAA)—characterized by the deposition of ß-amyloid in the walls of leptomeningeal vessels—is a common cerebral small vessel disease and a major cause of intracerebral hemorrhage in the elderly (1–3). Furthermore, it has become evident that CAA is associated with cognitive impairment (4). Specifically, it has been shown that ...

Combination of Dexmedetomidine and Ketamine for Magnetic Resonance Imaging Sedation
Conclusions: The efficacy of DEX–KET sedation was comparable to that of midazolam for MRI examination. DEX–KET was related to shorter scan time and lower occurrence of complications compared to midazolam. Introduction Neurocritically ill patients often require brain magnetic resonance imaging (MRI) in addition to conventional neurological evaluations. Brain MRI can reveal structural lesions with a high sensitivity due to its excellent spatial resolution and enhanced soft tissue contrast (1–3). To acquire MRI images, patients' cooperation is imperative. However, keeping patients with ...

Shengui Sansheng San Ameliorates Cerebral Energy Deficiency via Citrate Cycle After Ischemic Stroke
Conclusion In summary, SSS extraction significantly ameliorates cerebral energy metabolism via boosting citrate cycle, which mainly embodies the enhancements of blood glucose concentration, glucose and lactate transportation and glucose utilization, as well as the regulations of relative enzymes activities in citrate cycle. These ameliorations ultimately resulted in numerous ATP yield after stroke, which improved neurological function and infarcted volume. Collectively, it suggests that SSS extraction has exerted advantageous effect in the treatment of cerebral ischemia. Ethics Statement All animal operations were accor...
