Use of Mesenchymal Stem Cells in Pre-Clinical Models of Spinal Cord Injury

Spinal Cord Injury (SCI) is a devastating disease that causes disruption of sensorimotor function below the site of injury. Current management is based on surgical decompression of the neural tissue and pharmacotherapy; however, there is no gold standard treatment readily available for patients in the clinic. This indicates that novel therapeutic strategies for the treatment are still needed in the clinical setting. There are several alternatives that are currently under investigation for the treatment of this disease, with increasing focus in regenerative medicine treatments. Mesenchymal stem cells (MSCs) are one of the most promising candidates for stem cell therapy in SCI, as they are easily obtained, have high safety profiles, and help with neural regeneration in SCI mainly via release of trophic factors, neovascularization, and immunomodulation. In this work, authors provide an insight of the available MSC for neural regeneration, their therapeutic role, and the potential MSC-based therapies for SCI

In NPH, setting valve opening pressure close to lumbar puncture opening pressure decreases overdrainage

Background. The management of normal pressure hydrocephalus (NPH) can be difficult, partly because there are frequent treatment complications such as overdrainage which, when serious, may require surgical intervention. We previously reported a correlation between the difference of lumbar puncture opening pressure minus the valve opening pressure setting (LPOP–VOP) (which we refer to as the delta) and increased rates of overdrainage. This led to a modification in our practice, whereby we now set the VOP equal to, or close to, the LPOP, resulting in lower deltas. Objective. In this new study, our aim was to compare the rate of overdrainage in our patients with higher and lower deltas and assess the significance of setting the VOP equal, or close, to the patient’s LPOP. Methods. 1. We reproduced the association between delta and overdrainage. 2. We compared the incidence of overdrainage in those whose VOP was set close to LPOP (low delta) versus those with VOP setting distant from the LPOP (higher delta). 3. We compared symptom improvement in those with a low versus higher delta. Results. We confirmed the relation between high delta and an increased rate of overdrainage, lower rates of overdrainage in those whose VOP was set close to the LPOP (Delta Adjusted Practice), and better improvement of symptoms when the VOP was set closer to the LPOP. Conclusion. We propose that the initial VOP should be set as close as possible to the patient’s LPOP to decrease overdrainage without compromising symptom improvement

ARIA digital anamorphosis : Digital transformation of health and care in airway diseases from research to practice

Digital anamorphosis is used to define a distorted image of health and care that may be viewed correctly using digital tools and strategies. MASK digital anamorphosis represents the process used by MASK to develop the digital transformation of health and care in rhinitis. It strengthens the ARIA change management strategy in the prevention and management of airway disease. The MASK strategy is based on validated digital tools. Using the MASK digital tool and the CARAT online enhanced clinical framework, solutions for practical steps of digital enhancement of care are proposed.Peer reviewe

Real-time video-streaming to surgical loupe mounted head-up display for navigated meningioma resection

Wearable technology interfaces with normal human movement and function, thereby enabling more efficient and adaptable use.We developed a wearable display system for use with intra-operative neuronavigation for brain tumor surgery. The Google glass head-up display system was adapted to surgical loupes with a video-streaming integrated hardware and software device for display of the Stealth S7 navigation screen. Phantom trials of surface ventriculostomy were performed. The device was utilized as an alternative display screen during cranial surgery. Image-guided brain tumor resection was accomplished using Google Glass head-up display of Stealth S7 navigation images. Visual display consists of navigation video-streaming over a wireless network. The integrated system developed for video-streaming permits video data display to the operating surgeon without requiring movement of the head away from the operative field. Google Glass head-up display can be used for intra-operative neuronavigation in the setting of intracranial tumor resection

Geographic disparities in access to glioblastoma treatment based on Hispanic ethnicity in the United States: Insights from a national database

Access to treatment for glioblastoma (GBM) can be impacted by multiple demographic parameters. Barriers specific to the Hispanic population of the United States (US) are not fully understood. Therefore, the aim of this study was to elucidate geographic disparities for access to GBM treatment in the US Hispanic population. All GBM patients with known Hispanic ethnicity status (and Caucasian race) in the US National Cancer Database (NCDB) between the years 2005-2016 were retrospectively reviewed. Treatment statuses of surgical resection, chemotherapy, radiation therapy and triple therapy (resection, chemotherapy and radiation) were summarized, and analyzed by comparison and regression analyses over US Census regions. A total cohort size of 40,232 Caucasian GBM patients were included, with 3,111 (8%) identifying as Hispanic. The odds of treatment by chemotherapy (OR 0.78, P < 0.01), radiation therapy (OR 0.82, P < 0.01) and triple therapy (OR 0.84, P < 0.01) were all significantly lower in the Hispanic group versus non-Hispanic group. The odds of being treated in the Hispanic group were significantly lower in multiple Census regions with respect to surgical resection (New England, OR 0.51; Mountain, OR 0.68), chemotherapy (East North Central, OR 0.77; Middle Atlantic, OR 0.71; Pacific, OR 0.77), radiation therapy (Middle Atlantic, OR 0.77) and triple therapy (New England, OR 0.49; Middle Atlantic, OR 0.87; Pacific, OR 0.84). Significant barriers to triple therapy in the Hispanic group within these regions were older age (OR 0.97; P < 0.01), treatment in a community facility (OR 0.85, P = 0.03), lack of insurance (OR 0.71, P = 0.03), yearly income < $40,227 (OR 0.69, P < 0.01), low education levels (OR 0.75, P = 0.03) and presence of co-morbidity (OR 0.82; P < 0.01). Currently in the US, there exists heterogenous geographic disparities for Hispanic GBM patients to access different treatments compared to non-Hispanic patients. Multiple circumstances can influence access to treatment within the Hispanic community of these regions, and greater investigation with more granularity required to reveal mechanisms in which these disparities may be addressed in the future
