AIMS: Topical growth factors accelerate wound healing in patients with diabetic foot ulcers (DFU). Due to the absence of head to head comparisons, we carried out Bayesian network meta-analysis to compare the efficacy and safety of growth factors. METHODS: Using an appropriate search strategy, randomized controlled trials on topical growth factors compared with standard of care in patients with DFU, were included. Proportion of patients with complete healing was the primary outcome...

Transplantation of mesenchymal stem cells (MSCs) has emerged as an alternative strategy to treat knee osteoarthritis. In this context, MSCs derived from synovial fluid could provide higher chondrogenic and cartilage regeneration, presenting synovial fluid as an appropriate MSCs source. An allogeneic and biomimetic bioscaffold composed of Platelet Rich Plasma and synovial fluid that preserve and mimics the natural environment of MSCs isolated from knee has also been developed. We have optimized the cryopreservation of knee-isolated MSCs embedded within the aforementioned biomimetic scaffold, in order to create a reserve of young autologous embedded knee MSCs for future clinical applications...

<p>Hair loss is a complicated problem that causes significant concern for those who are affected. Patients seeking medical treatment have limited options that include topical minoxidil and oral finasteride. While these treatments are backed by long term clinical use and research outcomes, many patients find topical minoxidil difficult to incorporate into their daily routine and some are concerned with the side effects associated with finasteride. In the office setting, patients may be treated with more invasive procedures such as platelet-rich plasma injections (PRP) and hair transplantation, treatments that often must be repeated and can lead to a costly investment...

The healing of a muscle injury is a complex and dynamic process characterized by different overlapping phases resulting in the restoration of the anatomic continuity and function. This process, triggered by the tissue injury itself, is modulated by different growth factors capable of directing the recruitment, duplication, activation, and differentiation of different cell types. This key role played by different growth factors is the basis of the use of platelet-rich plasma in several circumstances, all of them characterized by the need of activating or ameliorating the process of tissue repair...

The spine has been the subject of extensive clinical research since it is the source of many painful complaints. However, there is little scientific evidence concerning the therapeutic proposals. During the course of life, the intervertebral disc degenerates, which over time diminishes its damping capacity and facilitates the expulsion of the nucleus pulposus through the annulus fibrosus. The degeneration of the intervertebral disc (DDI) is the origin of some back pain and various specific treatments have been developed...

Anti-beta-2-glycoprotein 1 (anti-β2GP1) antibodies are associated with increased thrombotic risk in patients with autoimmune disease. There is conflicting evidence on the effects of anti-β2GP1 antibodies on platelets, with both enhanced and inhibited aggregation previously reported. However, previous studies did not include isotype antibodies to ensure the observed effects were due to anti-β2GP1 antibodies. The aims of this study were to (1) investigate the effects of anti-β2GP1 antibodies on collagen-induced platelet aggregation in parallel with negative control (buffer normal saline) and isotype control antibodies and (2) determine the lupus anticoagulant (LA) activity of anti-β2GP1 antibodies used...
