Trancatheter heart valve (THV) thrombosis is effectively treated with anticoagulation but alternative therapies are required when a faster gradient reduction is needed. Open heart surgery has been rarely performed due to the high perioperative mortality and only five cases have been described so far. Here we describe a case of emergent surgical explantation for THV thrombosis after a valve-in-valve. A 67years old man underwent transcatheter aortic valve implantation for a failed surgical bioprosthesis Epic 21mm (St...

OBJECTIVE: We aimed to analyse the incidence of prosthesis-patient mismatch (PPM) and elevated gradients after aortic valve in valve (ViV), and to evaluate predictors and associations with clinical outcomes of this adverse event. METHODS: A total of 910 aortic ViV patients were investigated. Elevated residual gradients were defined as ≥20 mm Hg. PPM was identified based on the indexed effective orifice area (EOA), measured by echocardiography, and patient body mass index (BMI)...

Although central melanocortin 4 receptor (MC4R) blockade abolishes the CNS-mediated anorexogenic, antidiabetic and cardiovascular actions of leptin, chronic MC4R stimulation fails to completely mimic leptin's effects. Because neuropeptide Y (NPY) and MC4R exert opposite effects on cardiovascular and metabolic functions, we tested its role in offsetting the long-term actions of MC4R activation. Wild-type (WT) and NPY-deficient (NPY-/-) mice were implanted with telemetry probes for measuring mean arterial pressure (MAP) and heart rate (HR) 24-h/d...

Reconstruction of bone loss in the alveolar ridge has long been challenging. Autologous bone grafts are considered as the "golden standard", while little research has focused on how to repair pronounced alveolar bone defects after autologous bone graft failure. The aim of this study was to detail a method based on the titanium mesh technique coupled with particulate coral hydroxyapatite to solve the Onlay graft failure. With bone deficiency in the #11 and #24- #25 regions, we harvested two autologous bone blocks for reconstruction...

The interaction between TiO2 nanoparticles (NPs) and inflammatory cytokines, including CXCL8, a clinically relevant pro-inflammatory chemokine was investigated. TiO2 is present in tissues adjacent to failing implanted Ti (titanium) devices. TiO2 NPs were shown to bind to CXCL8 in vitro, causing perturbation of quantification of CXCL8 by ELISA, in both simple and complex protein panels, in a dose-dependent manner. Binding between TiO2 NPs and CXCL8 was demonstrated by protein gel electrophoresis. TiO2 NPs were also shown to inactivate the chemoattractant property of CXCL8 in a dose-dependent manner, suggesting that the binding between TiO2 NPs and CXCL8 is likely to be clinically relevant...

OBJECTIVES: The aim of this study was to determine whether the association of small label size of the surgical valve with increased mortality after transcatheter valve-in-valve (ViV) implantation is, at least in part, related to pre-existing prosthesis-patient mismatch (PPM) (i.e., a bioprosthesis that is too small in relation to body size). BACKGROUND: Transcatheter ViV implantation is an alternative for the treatment of patients with degenerated bioprostheses...

Purpose/Aim: In developing a novel peritoneal oxygenation therapy, catheters implanted into the peritoneal cavity became obstructed with omental tissue and prevented the infusion and removal of fluid from the peritoneal cavity. The obstruction of peritoneal catheters is a significant failure in researching various peritoneal treatments as further fluid administration is no longer possible. The purpose of this preliminary study was to determine the most effective catheter design for infusion and removal of fluid into the peritoneal cavity of rats...

BACKGROUND: Staple line leakage after bariatric surgery can be treated by endoscopic placement of a self-expandable stent. The success rate of stent placement is generally high, but migration is a frequent adverse event that hampers successful treatment. The Niti-S Beta stent is a fully covered double-bump stent that was specifically designed to prevent migration. This study aimed to evaluate the effectiveness and adverse event rate of the Niti-S Beta stent. METHODS: A retrospective study was performed in three high-volume bariatric centers...

In the present study we explore the implications of acquiring language when relying mainly or exclusively on input from a cochlear implant (CI), a device providing auditory input to otherwise deaf individuals. We focus on the time course of semantic learning in children within the second year of implant use; a period that equals the auditory age of normal hearing children during which vocabulary emerges and extends dramatically. 32 young bilaterally implanted children saw pictures paired with either matching or non-matching auditory words...

Because of its favourable haemodynamic characteristics and easy implantability, Mitroflow aortic valve bioprosthesis has been the valve of choice for many surgeons in patients with small aortic annulus. Disappointingly, early structural valve deterioration and high transvalvular gradients have been reported mostly in older patients with small prostheses. Reimplanting a new stented prosthesis sutured in a narrow and damaged annulus is technically challenging and demanding mainly in high-risk patients. Valve-in-valve transcatheter aortic valve implantation has been proposed as a viable option; however, it presents significant limitations because of residual high transprosthetic pressure gradients and risk of coronary occlusion...

Background: Non-union humeral shaft fractures are seen frequently in clinical practice at about 2-10% in conservative management and 30% in surgically operated patients. Osteosynthesis using dynamic compression plate (DCP), intramedullary nailing, locking compression plate (LCP), Ilizarov technique along with bone grafting have been reported previously. In cases of prior failed plate-screw osteosynthesis the resultant osteopenia, cortical defect, bone loss, scalloping around screws and metallosis, make the management of non-union more complicated...

Globozoospermia is characterized by the presence of 100% acrosomeless round-headed spermatozoa in an ejaculate. Failed fertilization after intracytoplasmic sperm injection (ICSI) is commonly reported for globozoospermic couples and can be overcome by artificial oocyte activation (AOA). Phospholipase C zeta (PLCζ) is one of the main sperm factors involved in oocyte activation and its low expression levels mainly account for fertilization failure. Deletion of the DPY19L2 gene is reported as a main genetic cause in over 70% of infertile men with globozoospermia...

Management of proximal and distal biceps tendon pathology is evolving. The long head of the biceps tendon, if inflamed, may be a pain-producing structure. In appropriately indicated patients, a symptomatic long head of the biceps tendon can be surgically managed via tenotomy, tenodesis, and/or superior labrum anterior to posterior repair. In some patients, primary superior labrum anterior to posterior pathology can be managed via biceps tenodesis. Determining which procedure is most appropriate and which technique and implant are preferred for a given patient with biceps tendon pathology is controversial...
