Role of Renal Dysfunction as a Prognostic Factor in Acute Stroke Patients at a Tertiary Hospital in Northeastern Nigeria
Saudi J Kidney Dis Transpl. 2021 Jan-Feb;32(1):199-203. doi: 10.4103/1319-2442.318524.ABSTRACTChronic kidney disease (CKD) and stroke share many common risk factors, and the presence of CKD confers added risk factors for stroke. With increasing interest and understanding of the close relationship between the kidney and the brain, this study aims to assess the prevalence and impact of renal dysfunction on outcomes acute stroke patients. This is a prospective hospital-based study carried out in the neurology unit of University of Maiduguri Teaching Hospital, Maiduguri, northeastern Nigeria. The study population consisted of ...

Stem cell therapy promotes recovery from stroke and dementia in mice
A one-time injection of an experimental stem cell therapy can repair brain damage and improve memory function in mice with conditions that replicate human strokes and dementia,a new UCLA study finds.Dementia can arise from multiple conditions, and it is characterized by an array of symptoms including problems with memory, attention, communication and physical coordination. The two most common causes of dementia are Alzheimer ’s disease and white matter strokes — small strokes that accumulate in the connecting areas of the brain.“It’s a vicious cycle: The two leading causes of dementia are almost always seen togeth...

Detection of Crossed Cerebellar Diaschisis by Intravoxel Incoherent Motion MR Imaging in Subacute Ischemic Stroke.
Abstract Intravoxel incoherent motion has received extensive attention in brain studies for its potential as a non-invasive magnetic resonance perfusion method. However, studies on intravoxel incoherent motion imaging and crossed cerebellar diaschisis detection are relatively scarce. The aim of our study was to evaluate the feasibility of using intravoxel incoherent motion imaging in crossed cerebellar diaschisis diagnosis in subacute ischemic stroke patients by comparing results from intravoxel incoherent motion imaging, single-photon emission computed tomography, and arterial spin-labeling perfusion methods. In ...

Anti-Platelet Therapy in Mild Cerebral Infarction Patients on the Basis of CYP2C19 Metabolizer Status.
This study aimed to investigate the effects of CYP2C19 metabolizer status on the clinical therapeutic efficacy of cerebral infarction. Patients with cerebral infarction ( n = 180; NIHSS score ≤ 5) were recruited and divided into Group A and Group B according to CYP2C19 metabolizer status. In Group A, patients received routine clopidogrel therapy for 1 year; in Group B, the patients with extensive metabolizer (EM) were treated with clopidogrel, and patients with intermediate metabolizer (IM) and poor metabolizer (PM) were treated with aspirin for 1 year. On admission, National Institutes of Health Stroke Scale score was d...

Scientists Restore Some Brain Activity in Recently Slaughtered Pigs
(NEW YORK) — Scientists restored some activity within the brains of pigs that had been slaughtered hours before, raising hopes for some medical advances and questions about the definition of death. The brains could not think or sense anything, researchers stressed. By medical standards “this is not a living brain,” said Nenad Sestan of the Yale School of Medicine, one of the researchers reporting the results Wednesday in the journal Nature. But the work revealed a surprising degree of resilience among cells within a brain that has lost its supply of blood and oxygen, he said. “Cell death in the brai...

The Successful Mechanical Lipectomy Treatment of Cerebral Fat Embolism following Autologous Fat Injection
Summary: Autologous fat injection is becoming a more and more widely accepted procedure in plastic surgery nowadays. Concomitantly, there are many complications. The most serious one is arterial fat embolism, for which there is only poor prognosis and no effective treatment. Here, we report the first case of successful treatment of cerebral fat embolization with the help of mechanical lipectomy. Our patient was found unconscious with left-sided hemiparesis after a facial fat injection surgery 4 hours before. Cerebral artery computed tomography angiography indicated it was multiple fat embolism. Then Solitaire stent (4 ×...

Intrathecal Injection of Allogenic Bone Marrow-Derived Mesenchymal Stromal Cells in Treatment of Patients with Severe Ischemic Stroke: Study Protocol for a Randomized Controlled Observer-Blinded Trial
AbstractMesenchymal stromal cells (MSCs) can differentiate into multiple tissues. Preclinical studies have shown that MSC-based therapy is a potential new treatment approach for ischemic stroke. These results support the urgent need for further studies of MSC transplantation in the treatment of ischemic stroke in humans. Here, we develop a prospective, randomized, controlled, observer-blinded phase II trial to assess the clinical safety, feasibility, and therapeutic mechanisms of allogenic bone marrow-derived MSCs (BM-MSCs) by intrathecal infusion in the treatment of patients with cerebral infarction within the middle cere...

Cell therapy for cerebral hemorrhage: Five year follow-up report.
Authors: Chang Z, Mao G, Sun L, Ao Q, Gu Y, Liu Y Abstract The aim of the study was to examine treatment of cerebral hemorrhages with bone-marrow or human umbilical cord-derived mesenchymal stem cells (BMSCs or Hu-MSCs) and conventional surgical approaches, and determine and compare the effectiveness, feasibility, safety and reproducibility of each method. A retrospective analysis was performed on a cohort of cell-treated cerebral hemorrhage patients from October 1, 2007 to October 1, 2009. A total of 24 patients, all of whom received conventional surgical treatment, were classified as follows: i) The control group...

A two-year follow-up study of co-transplantation with neural stem/precursor cells and mesenchymal stromal cells in ischemic stroke patients.
Abstract Stem cell therapy is an emerging therapeutic modality in the treatment of stroke. We assessed the safety and feasibility of the co-transplantation of neural stem/precursor cells (NSPCs) and mesenchymal stromal cells (MSCs) in patients with ischemic stroke. Eight patients were enrolled in this study. All patients had a hemisphere with infarct lesions located on one side of the territories of the cerebral middle or anterior arteries as revealed with cranial magnetic resonance imaging (MRI). The patients received one of the following two types of treatment: the first treatment involved 4 intravenous injectio...

Intracerebral Implantation of Autologous Peripheral Blood Stem Cells in Stroke Patients: a Randomized Phase II Study.
Abstract In our previous study, intracerebral implantation of peripheral blood stem cells (PBSC) improved functional outcome in rats with chronic cerebral infarction. Based on this findings, a randomized, single blind controlled study was conducted in 30 patients [PBSC group (n=15) and control group (n=15)] with middle cerebral artery infarction confirmed on T2?weighted MRI 6 months to 5 years after a stroke. Only subjects with neurological deficits of intermediate severity based on the National Institute of Health Stroke Scale (NIHSS) (range: 9?20) that had been stable for at least 3 months were enrolled. Those i...

Fat chance: Scientists unexpectedly discover stress-resistant stem cells in adipose tissue
Researchers from the UCLA Department of Obstetrics and Gynecology have isolated a new population of primitive, stress-resistant human pluripotent stem cells that are easily derived from fat tissue and are able to differentiate into virtually every cell type in the human body without genetic modification.   The cells, called multi-lineage stress-enduring stem cells from adipose tissue (Muse-AT), were discovered by "scientific accident" when a piece of equipment failed in the laboratory, killing all the stem cells in an experiment except the Muse-AT cells.   The UCLA team further discovered that not only are Muse-A...
