BACKGROUND: Controversy exists over the surgical treatment for severe patellofemoral osteoarthritis. We therefore wished to compare the outcome of patellofemoral arthroplasty (PFA) with TKA in a blinded randomized controlled trial. QUESTIONS/PURPOSES: In the first 2 years after surgery: (1) Does the overall gain in quality of life differ between the implants based on the area under the curve of patient-reported outcomes (PROs) versus time? (2) Do patients obtain a better quality of life at specific points in time after PFA than after TKA? (3) Do patients get a better range of movement after PFA than after TKA? (4) Does PFA result in more complications than TKA? METHODS: Patients were eligible if they had debilitating symptoms and isolated patellofemoral disease...

In recent years angiographic risk scores have been introduced in clinical practice to stratify different levels of risk after percutaneous coronary interventions (PCI). The SYNTAX score included all intermediate lesions in vessels ≥1.5 mm, consequently, multiple stent implantation was required. Four years ago, we built a new angiographic score in order to guide PCI strategy avoiding stent deployment both in intermediate stenosis as in small vessels, therefore these were not scored (ERACI risk score). The purpose of this mini review is to validate the strategy of PCI guided by this scoring, taking into account long term follow up outcomes of two observational and prospective registries where this policy was used...

Percutaneous therapies for congenital heart disease have been evolving rapidly despite limited investment from industry. The Melody transcatheter pulmonary valve (Medtronic, Inc, Minneapolis, MN USA) replacement therapy represents an important advancement in this arena. It has been approved in the United States for use in the pulmonary position, on a Humanitarian Device Exemption status. Off-label use of the Melody transcatheter pulmonary valve has extended to the mitral, pulmonary, and aortic valves, especially in previously implanted valves with prosthetic valve degeneration...

The severe worldwide shortage of donor organs, and severe pathologies placing patients at high risk for rejecting conventional cornea transplantation, have left many corneal blind patients untreated. Following successful pre-clinical evaluation in mini-pigs, we tested a biomaterials-enabled pro-regeneration strategy to restore corneal integrity in an open-label observational study of six patients. Cell-free corneal implants comprising recombinant human collagen and phosphorylcholine were grafted by anterior lamellar keratoplasty into corneas of unilaterally blind patients diagnosed at high-risk for rejecting donor allografts...

BACKGROUND AND AIMS: Target lesion restenosis is the most frequent complication after angioplasty and stenting for peripheral artery disease (PAD). MicroRNAs (miRs) regulate crucial pathophysiological processes leading to in-stent restenosis and thrombosis. The aim of this study was to investigate the predictive value of 11 miRs for the composite endpoint of target lesion restenosis and atherothrombotic events (primary endpoint), and target vessel revascularization (TVR, secondary endpoint) in 62 consecutive PAD patients after infrainguinal angioplasty with stent implantation...

PURPOSE: Recent studies suggest that atrial fibrillation (AF) is associated with increased cardiovascular risk and mortality including sudden cardiac death (SCD). According to the Cardiovascular Heath Study cohort, the incident rate of SCD was higher in the AF population (2.9 per 1000 per year) compared with non-AF controls (1.3 per 1000 per year). In this study, we performed a systematic review and meta-analysis to explore the association between AF and SCD. METHODS: We comprehensively searched the databases of MEDLINE and EMBASE from inception to January 2017...

BACKGROUND/OBJECTIVE: The major limitation of computer-based 3D fluoroscopy is the increased radiation exposure of patients and the operating room (OR) staff. Adjunction of spine navigation to intraoperative 3D fluoroscopy (io3DF) can likely overcome this shortcoming while increasing the pedicle screw accuracy rate. Thus, we compared data from a cohort of patients undergoing lumbar percutaneous pedicle screw (PPS) placement utilizing io3DF alone or in combination with spine navigation...
