In mammals, spinal cord injuries often result in muscle paralysis through the apoptosis of lower motor neurons and denervation of neuromuscular junctions. Previous research shows that the inflammatory response to a spinal cord injury can cause additional tissue damage after the initial trauma. To modulate this inflammatory response, we delivered lentiviral anti-inflammatory interleukin-10, via loading onto an implantable biomaterial scaffold, into a left-sided hemisection at the C5 vertebra in mice. We hypothesized that improved behavioral outcomes associated with anti-inflammatory treatment are due to the sparing of fine motor circuit components. We examined behavioral recovery using a ladder beam, tissue sparing using histology, and electromyogram recordings using intraspinal optogenetic stimulation at 2 weeks post-injury. Ladder beam analysis shows interleukin-10 treatment results in significant improvement of behavioral recovery at 2 and 12 weeks post-injury when compared to mice treated with a control virus. Histology shows interleukin-10 results in greater numbers of lower motor neurons, axons, and muscle innervation at 2 weeks post-injury. Furthermore, electromyogram recordings suggest that interleukin-10-treated animals have signal-to-noise ratios and peak-to-peak amplitudes more similar to that of uninjured controls than to that of control injured animals at 2 weeks post-injury. These data show that gene therapy using anti-inflammatory interleukin-10 can significantly reduce tissue damage and subsequent motor deficits after a spinal cord injury. Together, these results suggest that early modulation of the injury response can preserve muscle function with long-lasting benefits.Electronic supplementary materialThe online version of this article (10.1007/s13311-020-00946-y) contains supplementary material, which is available to authorized users.Key Words: Gene therapy, biomaterial, spinal cord injury, inflammation, neuromuscular junction 相似文献

Objectives
Reimbursement systems are evolving and endeavor to balance access and affordability. One such evolution in Ireland is the compulsory rapid review (RR) process, the outcome from which is a recommendation for a health technology assessment (HTA) or no HTA. For drugs that avoid an HTA, evaluation times are shorter, lengthy price negotiations are avoided, and access is faster. In the absence of formal decision-making criteria around the requirement of an HTA, this study examines the factors influencing the outcome of the RR process in Ireland.Methods
A database was developed combining data from publicly available sources for drug evaluations conducted by the National Centre for PharmacoEconomics (NCPE) (January 2010-June 2017, n = 296). Because Irish cost data were not publicly available for all drugs, cost data from the Scottish Medicines Consortium were employed as a proxy. Employing logistic regressions, the factors influencing the RR outcome are revealed.Results
After an RR, an HTA was recommended for 55% of drugs. The regression results revealed therapeutic area (endocrine, musculoskeletal, and neoplasm), first-in-class and orphan disease increased the probability of an HTA. Furthermore, when proxy costs were included, results revealed that every €1000 increase in annual drug costs per patient increased the probability of an HTA being required by 1% and that an HTA was more likely than no HTA when annual drug costs exceeded €15?000.Conclusion
Given the current focus on access and affordability, this study identifies the factors influencing the requirement of an HTA in Ireland. 相似文献995.

Telemedicine can serve as a platform for specialty collaboration and potentially address the lack of specialized and subspecialized care globally. In this article we present a case in which the use of teledermatology facilitated global collaboration between multiple specialists and subspecialists, resulting in high‐quality care of a child from a remote area of Botswana. We present the lessons learned and factors that should be considered when engaging in global specialty collaboration, especially between developed and developing countries. We also discuss the potential limitations of telemedicine when used within a global context. With these considerations in mind, global specialty collaboration facilitated by telemedicine can provide a potential solution to the lack of access to specialized and subspecialized care. 相似文献
