OBJECTIVE: Endovascular removal of emboli causing large vessel occlusion (LVO)-related stroke utilizing suction catheter and/or stent retriever technologies or thrombectomy is a new standard of care. Despite high recanalization rates, 40% of stroke patients still experience poor neurological outcomes as many cases cannot be fully reopened after the first attempt. The development of new endovascular technologies and techniques for mechanical thrombectomy requires more sophisticated testing platforms that overcome the limitations of phantom-based simulators...

Recurrent episodes of neurological dysfunction and white matter lesions in a young adult raise suspicion for multiple sclerosis (MS). However, occlusive retinopathy, hearing loss and absence of CSF oligoclonal bands are atypical for MS and should make the clinician consider an alternative diagnosis. We describe a man with hearing loss, visual signs and symptoms, and an accumulating burden of brain lesions, who was treated for a clinical diagnosis of MS for nearly two decades. Genetic testing revealed a unifying diagnosis...

Several cases have been reported of patients who experienced cerebral infarction following thoracoscope left lobectomy. Compared with right lung surgery, the pulmonary veins stump after left lobe surgery were longer and thrombosis was more likely. Besides, cases of cerebral infarction after right lung surgery are rarely reported. Left lobectomy is therefore considered as the main risk factor for postoperative cerebral infarction. However, here we report four cases of cerebral infarction after thoracoscopic wedge or segment resection of right lobe, which cause less damage to the pulmonary vein compared with lobectomy...

BACKGROUND: Pneumonia, the most common post-acute ischemic stroke (AIS) infection, accounts for up to 30% of deaths after a stroke. Multiple chronic inflammatory diseases, such as rheumatoid arthritis, psoriasis, and inflammatory bowel disease, are associated with increased risk of stroke and stroke morbidity. This study assessed the relationship between chronic inflammatory diseases and stroke-associated pneumonia (SAP). METHODS: Using data from the 2015-2017 National Inpatient Sample, we classified hospital discharges with a diagnosis of AIS as having ulcerative colitis, Crohn's disease, rheumatoid arthritis, psoriasis, systemic lupus erythematosus, other chronic inflammatory diseases, multiple chronic inflammatory diseases, or none...

Current diagnostics of sleep apnea relies on the time-consuming manual analysis of complex sleep registrations, which is impractical for routine screening in hospitalized patients with a high probability for sleep apnea, e.g. those experiencing acute stroke or transient ischemic attacks (TIA). To overcome this shortcoming, we aimed to develop a convolutional neural network (CNN) capable of estimating the severity of sleep apnea in acute stroke and TIA patients based solely on the nocturnal oxygen saturation (SpO2 ) signal...

BACKGROUND: The predictors of ischemic stroke in 'low-risk' patients with atrial fibrillation (AF) (CHA2 DS2 -VASc score 0 in men or 1 in women) are debated. OBJECTIVE: This study aimed to investigate the factors associated with ischemic stroke in 'low-risk' AF patients. Imaging characteristics of their ischemic strokes were also evaluated. METHODS: This was a matched case-control study conducted at a single tertiary institution. We identified 44 patients with de novo ischemic stroke, and incidentally found AF with low-risk CHA2 DS2 -VASc scores...

Abnormalities in thyroid hormones (TH) availability and/or metabolism have been hypothesized to contribute to Alzheimer's disease (AD) and to be a risk factor for stroke. Recently, 3-iodothyronamine (T1 AM), an endogenous amine putatively derived from TH metabolism, gained interest for its ability to promote learning and memory in the mouse. Moreover, T1 AM has been demonstrated to rescue the β-Amyloid dependent LTP impairment in the entorhinal cortex (EC), a brain area crucially involved in learning and memory and early affected during AD...

Glycosyltransferases are enzymes that catalyze the formation of a variety of glycoconjugates. Glycoconjugates play vital roles in the nervous system. β-1, 3-Galactosyltransferase 2 (B3galt2) is one of the major types of glycosyltransferases, which has not been reported in ischemia induced-brain injury. The purpose of this study was to explore the role of B3galt2 exerts and its underlying mechanism in cerebral ischemia in mice. Wild-type (WT) and heterozygous B3galt2 knockout (B3galt2-/+ ) mice were subjected to 90 min transient focal cerebral ischemia by middle cerebral artery occlusion (MCAO)...

BACKGROUND AND PURPOSE: Independent randomized-controlled clinical trials (RCTs) provided robust evidence for endovascular treatment (EVT) as the standard of care treatment for acute large vessel occlusions in the anterior circulation. We examined available studies specific to posterior cerebral circulation ischemic strokes to see if any conclusions can be drawn regarding endovascular treatment options. METHODS: We performed a systematic literature search to identify studies evaluating the safety and efficacy of EVT versus standard medical treatment for patients with acute basilar artery occlusion (BAO)...

Data obtained in primarily Caucasian (C) and African American adults show that ethnicity does not mediate responsiveness to exercise training. It is unknown if Hispanics (H), who face elevated health risks and are less active than C, exhibit a similar response to exercise training. This study compared cardiorespiratory and hemodynamic responses to high intensity interval training (HIIT) between C and H women. Twelve C and ten H women ages 19-35 yr who were non-obese and inactive completed nine sessions of HIIT over a 3 wk period...

Spatial neglect (SN) is a common cognitive disorder after brain injury. Prism adaptation treatment (PAT) is one of the promising interventions for SN albeit inconsistent results from previous studies. We carried out a comparison intervention (PAT vs. Sham) and aimed to evaluate the efficacy of PAT on visuospatial symptoms of SN in an inpatient rehabilitation setting that offered a highly intensive comprehensive brain injury rehabilitation program. A total of 34 patients with moderate-to-severe SN secondary to stroke or traumatic brain injury were randomized to the PAT group and the Sham group (an active control group)...

Severe neurodegenerative diseases such as Parkinson's disease or multiple sclerosis and acute events like stroke, spinal cord injuries or other related pathologies have been shown to negatively impact the central and peripheral nervous systems, thus causing severe impairments to mobility. The development and utilisation of exoskeletons as rehabilitation devices has shown good potential for improving patients' gait function. Ten older adults (age: 68.9 ± 9.2 yrs; height: 1.65 ± 0.08 m. mass: 71.6 ± 11.0 kg) affected by neurological diseases impacting their gait function completed a 10-session gait training protocol where they walked for 10 minutes wearing a passive exoskeleton assisting hip flexion, namely Exoband...
