NCT02041494
Hernias are often treated using a prosthetic mesh to add support to the healing wound. Prosthetic meshes have been used for decades to repair ventral hernias, level 1 data regarding which type of mesh to use is limited. The purpose of this study is to compare the effects, good and/or bad, of two types of prosthetic meshes: one that is made from pig skin (called a "biologic prosthetic"), and one that is made in a laboratory (called a "synthetic prosthetic"). This study will include some patients who have an infection in/near the hernia, and other patients who do not have an infection. We expect the synthetic mesh to be associated with a higher rate of early post-operative surgical site infection and fluid collections (seromas), while we expect the biologic mesh to be associated with a higher rate of recurrence.
NCT01893996
Rheumatoid arthritis patients are at increased risk of cardiovascular disease because of systemic inflammation that can persist even in patients with well-controlled joint disease. We hypothesize that adding an anti-tumor necrosis factor medication, adalimumab, to standard non-biologic therapy for rheumatoid arthritis will improve endothelial function (reduce cardiovascular risk) in these patients. The design of the trial is as follows: 18 month prospective, randomized, double-blind crossover trial comparing the addition of adalimumab to the addition of placebo. The primary endpoint is a change in endothelial cell function, as detected by brachial artery FMD, at 6 months of adalimumab treatment compared to 6 months of placebo.
