World-Wide Efficacy of Bone Marrow Derived Mesenchymal Stromal Cells in Preclinical Ischemic Stroke Models: Systematic Review and Meta-Analysis

Conclusions: Our results show worldwide efficacy of BM-MSCs in improving functional outcomes in pre-clinical animal models of stroke and support testing these cells in clinical trials in various ranges of time windows using different delivery routes. The continued growing number of publications showing functional benefit of BM-MSCs are now adding limited value to an oversaturated literature spanning 18 years. Researchers should focus on identifying definitive mechanisms on how BM-MSCs lead to benefit in stroke models. Introduction Ischemic stroke is the 5th leading cause of death and the leading cause of long term disability in the United States (1, 2). Currently, tPA is the only FDA approved medical, non-invasive treatment for ischemic stroke, its use restricted by a narrow time window of 3 h (4.5 h in certain eligible patients) after symptom onset. This has limited the use of tPA to only a fraction of ischemic stroke patients. Ischemic stroke results in a complex cascade of events leading to the loss of neural tissue, including neurons and their supporting structures (3, 4). Concurrently, there is an initiation of local and systemic inflammatory responses that evolve over a period of days, and the extent of which determines the eventual degree of damage (4). Considering the involvement of multiple parallel processes contributing to recovery, it is not surprising that stroke researchers have tested a multitude of investigational therapies for ischemic stroke with no s...

AbstractThis is a letter to the Editor concerning the recently published article by Zerem et al. The paper described a 12yo female with multisystem mitochondrial disorder (MID) due to the compound heterozygous variants c.1963_1964dupAT and p.Ile382Met inOPA1 manifesting phenotypically with congenital nystagmus, developmental delay, visual impairment, gait ataxia, epilepsy, a stroke-like episode (SLE) with encephalopathy and vomiting, and hearing impairment. This interesting case could be more meaningful by providing more information about the treatment of the SLE/stroke-like lesion (SLL), about the morphological characteri...

High blood pressure: A common diagnosis, that shows hardly any symptoms, but can be deadly. Hardened arteries and blood forced too hard against artery walls can lead to a heart attack or stroke. Fortunately, there are lifestyle improvements that can lower blood pressure and potentially save your life.

Abbott Laboratories has been wildly successful with its FreeStyle Libre continuous glucose monitor (CGM) since winning FDA approval in 2017, but it seems some investors and patients may be getting restless as the U.S. market waits for the second-generation of the blockbuster technology. We first noted some signs of impatience for Libre 2 in our coverage of Abbott's third-quarter earnings call in October. One reader commented on that article that "I don’t particularly care about investors becoming impatient, as a Freestyle Libre user I am growing impatie...

ConclusionLig exerts renoprotective functions in an animal model of DN mediated by antioxidant action, inhibition of apoptosis, anti-inflammatory action, reduction of renal fibrosis, reduction of the proliferation of mesangial cells, inhibition of endotheliosis, inhibition of atherosclerosis and promotion of renal autophagy. The positive conclusion should be treated cautiously because of various methodological flaws. Further studies are recommended according to ARRIVE guidelines. The method of modeling with high-dose STZ should be avoided and improved STZ modeling schemes are recommended. Considering the large dosage range...

Our objective was to develop comprehensive national estimates of the total burden of herpes zoster (HZ) among U.S. adults, including direct (ie, medical costs) and indirect (ie, productivity losses) costs, as well as its psychosocial impact (ie, quality of life losses). Using a patient-level microsimulation model, we projected health and economic outcomes among U.S. adults aged 18 years and older using a 10-year time horizon. We conducted a comprehensive systematic literature review to generate parameter values and conducted simulation modeling to generate our outcomes, including numbers of cases of uncomplicated HZ, posth...

Neuropathic pain causes severe suffering, and most patients are resistant to current therapies. A core element of neuropathic pain is the loss of inhibitory tone in the spinal cord. Previous studies have shown that foetal GABAergic neuron precursors can provide relief from pain. However, the source of these precursor cells and their multipotent status make them unsuitable for therapeutic use. Here, we extend these findings by showing, for the first time, that spinally transplanted, terminally differentiated human induced pluripotent stem cell-derived GABAergic (iGABAergic) neurons provide significant, long-term, and safe r...
