Nevertheless, high rates of complications affect the surgical treatment. Implant fixation, poor-quality tissue ingrowth and mesh shrinkage seem to be involved in postoperative complications, discomfort and chronic pain following inguinal hernia repair. To address these issues a multilamellar shaped 3D dynamic responsive prosthesis has been developed. This new implant, positioned fixation-free to obliterate the hernia opening, thanks its inherent dynamic compliance during inguinal movements, has demonstrated to induce an enhanced biological response. The ingrowth of newly formed muscle fibers, arteries and veins in a surrounding of viable connective tissue could be evidenced into the implant fabric. This appears to be quite different from the fibrotic plaque, typical biologic response of conventional meshes. In addition to myocytes and vessels, newly ingrown nerves have also been detected in the prosthetic structents of the groin. BACKGROUND It remains uncertain whether there is a benefit to perioperative beta-blocker use on outcomes after non-cardiac surgery. This meta-analysis aims to update the evidence regarding the associations between beta-blocker exposure and patient major short-term outcomes following non-cardiac surgery. METHODS Pubmed, Embase, and the Cochrane Central Register from their inception to May 2019 were searched by two independent authors. Observational studies reporting associations between perioperative beta-blocker treatment and short-term outcomes including 30-day all-cause mortality (ACM), 30-day major adverse cardiovascular events (MACE) and 30-day stroke risk were selected for inclusion. Meta-analyses were carried out by using random effects models. RESULTS Nineteen studies with a total of 1,711,766 participants were identified. Beta-blocker exposure was associated with reduced 30-day all-caus
