Mesenchymal stem cells (MSCs) offer promise as therapeutic aids in the repair of tendon and ligament disorders in sport horses. Equine allogeneic MSCs derived from umbilical cord blood (eUCB-MSCs) can be obtained in a minimally invasive fashion with successful propagation of MSCs.The objective of this study was to determine the applicability and therapeutic effect of eUCB-MSCs on tendinitis of the superficial digital flexor tendon, desmitis of the suspensory ligament, tendinitis of the deep digital flexor tendon, and desmitis of the inferior check ligament in clinical cases.A retrospective clinical study was performed. At two equine clinics, 52 warmblood horses were treated with cultured eUCB-MSCs between 2009 and 2012. About 2-10 × 10(6) cells per lesion were administered. When a lesion was treated twice, the total amount could run up to 20 × 10(6) cells. Pearson's chi-squared test was used to compare the effect of the injured structure on the success rate, as well as the effect of the age of the horse.Based on repeated examinations, 40 horses (77%) returned to work on the same or a higher level based on information provided by the owner. Neither the injured structure nor the age of the horse had a statistically significant influence on the result.Overall, the results of treatment of some tendon and ligament injuries with eUCB-MSCs in clinical cases are promising.

This study was designed as an economic evaluation alongside a randomized clinical trial. The object of this study was to evaluate the 1-year cost-effectiveness of surgical treatment of morbid obesity comparing two operations.100 patients were assigned randomly to vertical banded gastroplasty (VBG) or Lap-Band surgery. Both medical and non-medical costs were identified and measured. Costs data were combined with percentage Excess Weight Loss (%EWL) and with Quality Adjusted Life Years (QALYs) to obtain cost per %EWL and cost per QALY ratios.At 1 year, the total costs were not significantly different between both groups (95% confidence interval E5,999-E1,765). Also, the QALY gain after surgery was not significantly different between the two groups. However, %EWL was significantly higher in the VBG group compared to the Lap-Band group, P-value .0001. The estimated incremental cost per %EWL was E105.83 (E1,885.91/-17.82). For the costs per QALY, the estimated ratio was dominant. The overall mortality in this study was 2%. 2 patients in the VBG group died within 30 days after surgery; 1 of these deaths was possibly related to the VBG procedure.At 1 year after surgery, the costs and QoL of the two treatment modalities were found to be equal. Therefore, the selection of the procedure can be based on the clinical aspects, effectivity and safety at 1 year. In addition, the results of a long-term cost-effectiveness analysis (e.g. with a follow-up of 36 months) planned in the future can also be helpful in the selection of the preferred treatment.
