ABSTRACT

Current treatment for corneal endothelial dysfunction consists in the replacement of corneal endothelium by keratoplasty. Owing to the scarcity of donor corneas and the increasing number of transplants, alternative treatments such as cell-based therapies are necessary. In this article, we highlight the biological aspects of the cornea and the corneal endothelium, as well as the context that surrounds the need for new alternatives to conventional keratoplasty. We then review some of those experimental treatments in more detail, focusing on the development of the in vitro and preclinical phases of two cell-based therapies: tissue-engineered endothelial keratoplasty (TE-EK) and cell injection. In the case of TE-EK graft construction, we analyse the current progress, considering all the requirements it must meet in order to be functional. Moreover, we discuss the inherent drawbacks of endothelial keratoplasties, which TE-EK grafts should overcome in order to make surgical intervention easier and to improve the outcomes of current endothelial keratoplasties. Finally, we analyse the development of preclinical trials and their limitations in terms of performing an optimal functional evaluation of cell-based therapy, and we conclude by discussing early clinical trials in humans.

ABSTRACT

OBJECTIVE: The aim of this study was to do a cost-benefit analysis of myofascial release therapy (MRT) compared to manual therapy (MT) for treating occupational mechanical neck pain. METHODS: Variables regarding the outcomes of the intervention were intensity of neck pain, cervical disability, quality of life, craniovertebral angle, and ranges of cervical motion. Costs were assessed based on a social perspective using diary costs. Between-groups differences in average cost, cost-effectiveness, and cost-utility ratios were assessed using bootstrap parametric techniques. The economic cost-benefit evaluation was with regard to an experimental parallel group study design. There were 59 participants. RESULTS: Myofascial released therapy showed significant improvement over MT for cervical mobility (side bending, rotation, and craniovertebral angle). The total cost of MRT was approximately 20% less (-$519.81; 95% confidence interval, -$1193.67 to $100.31) than that of MT, although this was not statistically significant. Cost-effectiveness and cost-utility ratios showed that MRT could be associated with lower economic costs. CONCLUSION: With probabilities of 93.9% and 95.8%, MRT seems to be cost-effective for treating mechanical neck pain without the need to add any additional cost to obtain a better clinical benefit. Consequently, we believe it could be included in the clinical practice guidelines of different Spanish health care institutions.
