Correlation of Body Composition and Nutritional Status with Functional Recovery in Stroke Rehabilitation Patients.

Nutrients 2020 Jun 29;12(7). Epub 2020 Jun 29.

Department of Rehabilitation Medicine, Dokkyo Medical University, 880, Kitakobayashi, Mibu, Shimotsuga, Tochigi 3210293, Japan.

Previous studies have suggested that the nutritional status after stroke is independently associated with long-term outcomes and that sarcopenia delays poststroke rehabilitation and worsens the prognosis. However, many stroke patients have a deteriorated nutritional status and a decreased muscle mass in the acute phase. This prospective study included 179 patients who were admitted to the stroke rehabilitation unit. Read More

Zeb2 Is a Regulator of Astrogliosis and Functional Recovery after CNS Injury.

Cell Rep 2020 Jun;31(13):107834

Burke Neurological Institute, 785 Mamaroneck Avenue, White Plains, NY 10605, USA; Feil Family Brain and Mind Research Institute, Weill Cornell Medicine, 1600 York Avenue, New York, NY 10065, USA; Department of Chemistry and Life Science, United States Military Academy, West Point, NY 10996, USA. Electronic address:

The astrocytic response to injury is characterized on the cellular level, but our understanding of the molecular mechanisms controlling the cellular processes is incomplete. The astrocytic response to injury is similar to wound-healing responses in non-neural tissues that involve epithelial-to-mesenchymal transitions (EMTs) and upregulation in ZEB transcription factors. Here we show that injury-induced astrogliosis increases EMT-related genes expression, including Zeb2, and long non-coding RNAs, including Zeb2os, which facilitates ZEB2 protein translation.

Grafted human pluripotent stem cell-derived cortical neurons integrate into adult human cortical neural circuitry.

Stem Cells Transl Med 2020 Jun 29. Epub 2020 Jun 29.

Lund Stem Cell Center, Lund University, Lund, Sweden.

Several neurodegenerative diseases cause loss of cortical neurons, leading to sensory, motor, and cognitive impairments. Studies in different animal models have raised the possibility that transplantation of human cortical neuronal progenitors, generated from pluripotent stem cells, might be developed into a novel therapeutic strategy for disorders affecting cerebral cortex. For example, we have shown that human long-term neuroepithelial-like stem (lt-NES) cell-derived cortical neurons, produced from induced pluripotent stem cells and transplanted into stroke-injured adult rat cortex, improve neurological deficits and establish both afferent and efferent morphological and functional connections with host cortical neurons.

Bringing proportional recovery into proportion: Bayesian modelling of post-stroke motor impairment.

Brain 2020 Jun 29. Epub 2020 Jun 29.

School of Psychology, University of Birmingham, Birmingham, UK.

Accurate predictions of motor impairment after stroke are of cardinal importance for the patient, clinician, and healthcare system. More than 10 years ago, the proportional recovery rule was introduced by promising that high-fidelity predictions of recovery following stroke were based only on the initially lost motor function, at least for a specific fraction of patients. However, emerging evidence suggests that this recovery rule is subject to various confounds and may apply less universally than previously assumed. Read More

Pentraxin 3 contributes to neurogenesis after traumatic brain injury in mice.

Neural Regen Res 2020 Dec;15(12):2318-2326

Department of Neurosurgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China.

Emerging evidence indicates that pentraxin 3 is an acute-phase protein that is linked with the immune response to inflammation. It is also a newly discovered marker of anti-inflammatory A2 reactive astrocytes, and potentially has multiple protective effects in stroke; however, its role in the adult brain after traumatic brain injury is unknown. In the present study, a moderate model of traumatic brain injury in mice was established using controlled cortical impact. Read More
