Abstract
Total joint arthroplasty (TJA) is a common procedure performed throughout the entire world in hopes of alleviating debilitating hip or knee pain. The projected number of TJAs performed in the United States alone is projected to exceed 1.9 million by 2030 and 5 million by 2040. With the significant increase in TJA performed, more periprosthetic joint infections (PJIs) are likely to be encountered. PJIs are a devastating complication of TJA. The economic and clinical burden must be understood and respected to minimize occurrence and allow optimal patient outcomes.

Abstract
In evergreen oak leaves collected at a western Mediterranean site (Var, France), the amounts of both hydrolyzable and condensed tannins decrease through the depth of the leaf litter. The decrease in condensed tannins could be partly explained by the cellular degradation of the lower epidermis and the mesophyll of leaves, as observed in histological sections. However, the condensed tannins may also be degraded by microbial enzymes because their average molecular weight decreased by about 50%. In contrast, the decrease in hydrolyzable tannins seems to be initiated by microbial enzymatic action, which is then followed by the same degradation process described above.
