An assessment of the effectiveness of hyaluronic acid and polyacrylamide hydrogel in horses with osteoarthritis: Systematic review and network meta-analysis.

For several years, hyaluronic acid (HyA) and, more recently, polyacrylamide hydrogel (PHyd) have been used to reduce lameness and pain caused by osteoarthritis. However, there is still a lack of scientific evidence of the efficacy of these substances to allow veterinary experts to make decisions about their use in horses. The objective of this study was to evaluate, through a systematic review and network meta-analysis (NMA), the efficacy of HyA, associated or not with other drugs, and PHyd in relieving lameness in horses with osteoarthritis. The searches for primary studies were conducted on four search platforms. The efficacy of HyA and PHyd was estimated through the relative risk difference method. Heterogeneity was observed in the efficacy of HyA, indicating long-term ineffectiveness of this drug when associated or not with anti-inflammatory drugs. In contrast, the results indicate that PHyd is an effective alternative therapy, with a long period of action in reducing lameness in horses with osteoarthritis. This study provides evidence that the application of PHyd and HyA is effective in reducing lameness caused by osteoarthritis in horses at different time periods, where PHyd has a longer time of action.

Analysis of the perception and behavior of consumers regarding capybara meat by means of exploratory methods.

The objective of this work was to identify the perception of consumers regarding the consumption of capybara meat, as well as to generate information that will help in the development of the productive chain of the species. Free word association and application of a questionnaire containing questions were performed. We classified dimensions with categories related to the words of greatest impact mentioned. Through the method of word association, it was noticed that terms related to taste and aroma were the most cited. From the 14 factors explored by the questionnaire, four were identified as responsible for explaining 71% of the total common variance of the variables. The exploratory and confirmatory factorial analysis showed that four factors were sufficient to measure the main characteristics that should be considered in marketing strategies by the industries and breeders who want to increase the consumption of capybara meat. These main factors were animal welfare, price, quality and the dissemination of the benefits of meat.
