Deep Hypothermia With Retrograde Cerebral Perfusion Versus Moderate Hypothermia With Antegrade Cerebral Perfusion for Arch Surgery
This study compared two different established neuroprotective strategies in patients undergoing elective transverse hemiarch replacement.MethodsTwenty patients undergoing hemiarch replacement were prospectively randomized to receive deep hypothermic circulatory arrest with retrograde cerebral perfusion (DHCA+RCP) or moderate hypothermic circulatory arrest with antegrade cerebral perfusion (MHCA+ACP). All patients received neurologist-adjudicated examinations and magnetic resonance imaging before discharge. The primary end point was a composite of stroke, transient ischemic attack, and magnetic resonance imaging–adjudicated injury. Secondary end points were transient neurologic dysfunction, and the National Institutes of Health Stroke Scale, and neurocognitive scores.ResultsRandomization resulted in 11 DHCA+RCP patients and 9 MHCA+ACP patients. There was no difference in cardiopulmonary bypass, cross-clamp, or circulatory arrest times. MHCA+ACP patients underwent circulatory arrest at significantly warmer temperatures (26.3° ± 1.8°C) than DHCA+RCP patients (19.9° ± 0.1°C, p
Authors: Sabet Sarvestani F, Azarpira N Abstract Heart and cerebral infarctions, as two important ischemic diseases, lead to the death of tissues due to inadequate blood supply and high mortality worldwide. These statuses are started via blockage of vessels and depletion of oxygen and nutrients which affected these areas. After reperfusion and restoration of oxygen supply, more severe injury was mediated by multifaceted cascades of inflammation and oxidative stress. microRNAs (miRNAs) as the regulator of biological and pathological pathways can adjust these conditions by interaction with their targets. Also, miRNAs...

CONCLUSIONS: Young adult IS patients in Korea exhibit low awareness and poor management of their risk factors. Although the short-term outcome was relatively favorable in those patients, having SLE was associated with unfavorable outcomes. More attention needs to be paid for improving awareness and controlling risk factors in this population. PMID: 33029967 [PubMed]
Authors: Kim EH, Shim WH, Lee JS, Yoon HM, Ko TS, Yum MS Abstract BACKGROUND AND PURPOSE: Recent quantitative neuroimaging studies of childhood absence epilepsy (CAE) have identified various structural abnormalities that might be involved in the onset of absence seizure and associated cognitive and behavioral functions. However, the neuroanatomical alterations specific to CAE remain unclear, and so this study investigated the regional alterations of brain structures associated with newly diagnosed CAE. METHODS: Surface and volumetric magnetic resonance imaging data of patients with newly diagnosed CAE (n=18) an...
CONCLUSIONS: Paramagnetic rims might be a characteristic MRI finding for MS, and therefore they have potential as an imaging marker for differentially diagnosing MS from NMOSD using 3-T MRI. PMID: 33029961 [PubMed]
Conclusions: High-quality randomized evidence indicates that therapeutic hypothermia is associated with higher mortality and no difference in good neurologic outcome compared with normothermia in critically ill patients. Although there still might be a possibility that therapeutic hypothermia is beneficial in a specific setting, routine application of therapeutic hypothermia would better be avoided outside the settings indicated by international guidelines (adult cardiac arrest and hypoxic-ischemic encephalopathy of newborns).
