Background Reconstruction of craniofacial bone defects is a primary focus of craniofacial surgery. Although autogenous bone grafts remain as the gold standard, alloplastic materials have also gained widespread popularity due to their off-the-shelf availability, ease of use, and durability. In addition to replacing the missing bone, some of these alloplastic materials have also been found to induce new bone formation. Objectives In this study, the phenomenon of neo-osseous induction with bioactive glass was investigated for different implant-soft tissue configurations...

Implantation of synthetic material, including vascular grafts, pacemakers, etc. results in the foreign body reaction and the formation of multinucleated giant cells (MGCs) at the exterior surface of the implant. Despite the long-standing premise that fusion of mononucleated macrophages results in the formation of MGCs, to date, no published study has shown fusion in context with living specimens. This is due to the fact that optical-quality glass, which is required for the majority of live imaging techniques, does not promote macrophage fusion...

Ischaemic heart disease and the heart failure that often results, remain the leading causes of death and disability in Europe and worldwide. As such, in order to prevent heart failure and improve clinical outcomes in patients presenting with an acute ST-segment elevation myocardial infarction and patients undergoing coronary artery bypass graft surgery, novel therapies are required to protect the heart against the detrimental effects of acute ischaemia/reperfusion injury. During the last three decades, a wide variety of ischaemic conditioning strategies and pharmacological treatments have been tested in the clinic - however, their translation from experimental to clinical studies for improving patient outcomes has been both challenging and disappointing...

Background: Clinical epidemiology data for young adults on renal replacement therapy (RRT) are lacking. While mostly transplanted, they have an increased risk of graft loss during young adulthood. Methods: We combined the UK Renal Registry paediatric and adult databases to describe patient characteristics, transplantation and survival for young adults. We grouped patients 11-30 years of age starting RRT from 1999 to 2008 by age band and examined their course during 5 years of follow-up...

BACKGROUND: Dislocation of the proximal tibiofibular joint is a complex injury that is often overlooked or misdiagnosed. Surgical management is recommended for severe acute or for chronic symptomatic instability of the proximal tibiofibular joint. Although the anterior ligamentous complex has been reported to be stronger than the posterior complex, biomechanical data are lacking. PURPOSE: To determine the ultimate load of the anterior and posterior ligamentous complexes of the proximal tibiofibular joint to determine optimal graft selection...

Mesenchymal stromal cells (MSCs) are committed progenitors of mesodermal origin that are found virtually in every organ and exhibit multilineage differentiation into osteocytes, adipocytes and chondrocytes. MSCs also mediate a wide spectrum of immunoregulatory activities that usually dampen innate and adaptive immune responses. These features have attracted interest in the perspective of developing novel cell therapies for autoimmune disease. However, depending on the microenvironmental conditions, MSCs may show a plastic behavior and switch to an immunostimulatory phenotype...

OBJECTIVE: Patients postcoronary artery revascularization surgery often receives blood product transfusion, which could delay their intensive care unit and hospital discharge. We investigated our robotic-assisted direct coronary artery bypass (RADCAB) transfusion rate to determine whether performing the minimal invasive coronary surgery with percutaneous coronary intervention in one stage would increase the incidence of blood transfusion, morbidity, and length of stay. METHODS: Between November 2003 and November 2015, 483 consecutive patients underwent RADCAB surgery...

OBJECTIVE: Hybrid coronary revascularization offers and combines the advantages of both surgical and percutaneous revascularization and eliminates at the same time the disadvantages of both procedures. The objective of this study was to assess graft and stent patency at 6 months, rate of bleeding, intensive care unit and hospital stay, rate of reintervention, and long-term clinical follow-up. METHODS: From March 2004 to November 2015, a total of 203 patients underwent robotic-assisted minimally invasive direct coronary artery bypass graft of the left internal thoracic artery to the left anterior descending artery and PCI of a non-left anterior descending vessel in a single or two stage, at three different centers...

Injuries to the central slip of the extensor mechanism can lead to a Boutonniere deformity with important functional consequences. We report a series of 11 patients treated by lengthening-dorsalizing the lateral bands and tightening the central slip with early mobilization. The average age of the patients was 42 years (14;52). The extension defect of the proximal interphalangeal (PIP) joint was 64 degrees (80;55) and the hyperextension of the distal interphalangeal joint was 10 degrees (15;5). The surgery was performed with peripheral nerve block (sensitive), allowing dynamic adjustment of the tendinous sutures...

Transplant renal vein thrombosis usually occurs early after surgery with a reported prevalence of 0.1% to 4.2%. It is a devastating event that ultimately leads to graft loss in almost all cases. There are many predisposing factors related to donor, recipient, surgery, and immunosuppression, with mechanical factors being considered the most common causes of transplant renal vein thrombosis. The clinical manifestations of acute renal vein thrombosis are nonspecific and are not dissimilar to the features of urine leak, urinary obstruction, or severe acute rejection...

OBJECTIVE The operative management of patients with adult spinal deformity (ASD) has a high complication rate and it remains unknown whether baseline patient characteristics and surgical variables can predict early complications (intraoperative and perioperative [within 6 weeks]). The development of an accurate preoperative predictive model can aid in patient counseling, shared decision making, and improved surgical planning. The purpose of this study was to develop a model based on baseline demographic, radiographic, and surgical factors that can predict if patients will sustain an intraoperative or perioperative major complication...

Due to the poor regenerative capacity of adult mammalian skin, there is a need to develop effective skin substitutes for promoting skin regeneration after a severe wound. However, the complexity of skin biology has made it difficult to enable perfect regeneration of skin. Thus, animal models are being used to test potential skin substitutes. Murine models are valuable but their healing process involves dermal contraction. We have developed a device called a dome that is able to eliminate the contraction effect of rodent skin while simultaneously housing a bioengineered skin graft...
