Intestinal Epithelial Stem Cell Transplants as a Novel Therapy for Cerebrovascular Stroke
Brain Behav Immun. 2022 Oct 31:S0889-1591(22)00420-2. doi: 10.1016/j.bbi.2022.10.015. Online ahead of print.ABSTRACTAlmost 2/3rds of stroke survivors exhibit vascular cognitive impairment and a third of stroke patients will develop dementia 1-3 years after stroke. These dire consequences underscore the need for effective stroke therapies. In addition to its damaging effects on the brain, stroke rapidly dysregulates the intestinal epithelium, resulting in elevated blood levels of inflammatory cytokines and toxic gut metabolites due to a 'leaky' gut. We tested whether repairing the gut via intestinal epithelial stem cell (IE...

Ephrin-B2 PB-mononuclear cells reduce early post-stroke deficit in diabetic mice but not long-term memory impairment
CONCLUSIONS: Intravenous PB-MNC+ administration the day after stroke induction in diabetic mice improved sensorimotor deficit and reduced infarct volume at the short term, but was unable to prevent long-term memory loss. To what extent diabetes impacts on cell therapy efficacy will have to be specifically investigated in the future. Including vascular risk factors systematically in preclinical studies of cell therapy will provide a comprehensive understanding of the mechanisms potentially limiting cell efficacy and also to identify good and bad responders, particularly in the long term.PMID:34520725 | DOI:10.1016/j.expneurol.2021.113864

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...

Research Articles Patient-derived glial enriched progenitors repair functional deficits due to white matter stroke and vascular dementia in rodents
Subcortical white matter stroke (WMS) accounts for up to 30% of all stroke events. WMS damages primarily astrocytes, axons, oligodendrocytes, and myelin. We hypothesized that a therapeutic intervention targeting astrocytes would be ideally suited for brain repair after WMS. We characterize the cellular properties and in vivo tissue repair activity of glial enriched progenitor (GEP) cells differentiated from human-induced pluripotent stem cells, termed hiPSC-derived GEPs (hiPSC-GEPs). hiPSC-GEPs are derived from hiPSC–neural progenitor cells via an experimental manipulation of hypoxia inducible factor activity by brie...

Excess mortality due to COVID-19 in Germany
SARS-CoV-2 is transmitted by droplets and likely aerosols. The median incubation period is about 5-6 days (range 1-14 days)1 and the median age at confirmed infection in Germany is 49 years. Typical symptoms include fever, cough, anosmia, ageusia, and pneumonia. The mortality rate of COVID-19 is higher among elderly and among ethnicities other than Caucasians. Furthermore, a markedly higher mortality rate has been observed for several comorbidities including obesity class II (BMI 35 •0-39•9 kg/m2) and III (BMI 40•0+ kg/m2), uncontrolled diabetes mellitus, malignancies in the previous year, severely reduced glomerular...

Neurological Involvement in Primary Systemic Vasculitis
Conclusion Neurological involvement is a common complication of PSV (Table 1), and neurologists play an important role in the identification and diagnosis of PSV patients with otherwise unexplained neurological symptoms as their chief complaint. This article summarizes the neurological manifestations of PSV and hopes to improve neuroscientists' understanding of this broad range of diseases. TABLE 1 Table 1. Common CNS and PNS involvements of primary systemic vasculitis. Author Contributions SZ conceived the article and wrote the manuscript. DY and GT reviewed and edited the manuscript. All authors ...

Deep Brain Stimulation for Amelioration of Cognitive Impairment in Neurological Disorders: Neurogenesis and Circuit Reanimation.
Abstract Acute (e.g., traumatic brain injury or stroke) and chronic (e.g., dementia or Parkinson's disease dementia) neurological disorders that involve cognitive impairment and dysfunctional neural circuits always lead to a dreadful and costly experience for patients and their families. The application of deep brain stimulation for the treatment of neuropsychiatric disorders has shown great potential to modulate pathological neural circuits and trigger endogenous neurogenesis. We summarize several important clinical and translational studies that utilize deep brain stimulation to improve cognition based on the po...

Cerebral Small Vessel Disease.
Abstract Cerebral small vessel disease (CSVD) is composed of several diseases affecting the small arteries, arterioles, venules, and capillaries of the brain, and refers to several pathological processes and etiologies. Neuroimaging features of CSVD include recent small subcortical infarcts, lacunes, white matter hyperintensities, perivascular spaces, microbleeds, and brain atrophy. The main clinical manifestations of CSVD include stroke, cognitive decline, dementia, psychiatric disorders, abnormal gait, and urinary incontinence. Currently, there are no specific preventive or therapeutic measures to improve this c...

Neurocognitive deficits in older patients with cancer
ConclusionNeurocognitive deficits (MCI and dementia) are more common in older adults with cancer. Factors associated with neurocognitive deficits include high comorbidity, stroke, warfarin use and metastatic cancer. Identification and management of these conditions is of great relevance in the course of cancer therapy.

Hospice and Palliative Medicine Clinician Views of Deactivation of Ventricular Assist Devices at End of Life
Left ventricular assist devices (LVADs) provide circulatory support to patients with advanced heart failure. These devices are used as a temporary bridge to recovery, bridge to cardiac transplantation, or as destination therapy (DT)—where the patient will have the device in situ for the remainder of his/her life. Compared to medical management alone, LVAD-DT often improves survival and quality of life for patients with severe heart failure.1 However, patients with LVADs may experience a host of challenges including a catastrophic event (e.g., stroke, hemorrhage, infection), a concurrent slow decline in health (e.g., righ...
