Label-free electrochemical biosensor for direct detection of Oncostatin M (OSM) inflammatory bowel diseases (IBD) biomarker in human serum.

Oncostatin M (OSM) is an interleukin-6 (IL-6) member family cytokine implicated in the pathogenesis of chronic diseases including inflammatory bowel disease (IBD). OSM is a novel diagnostic biomarker over-expressed in the serum of IBD patients. This paper reports on the first electrochemical OSM immunosensor, developed using a multistep fabrication process aimed at covalently immobilizing OSM antibodies on a mixed self-assembled monolayer coated gold working electrode.

Development of an MIP based electrochemical sensor for TGF-β1 detection and its application in liquid biopsy.

Oral cancer is one of the most common types of cancer in Europe and its large diffusion requires, together with prevention, the development of low-cost and reliable portable platforms for its diagnosis, with features of high selectivity and sensitivity. In this study, the development and characterization of a molecularly imprinted polymer (MIP)-based electrochemical sensor for TGF-β1 detection are reported. The optimized biosensor is a potential tool for the early screening of oral cancer.

Percutaneous Retrieval of a Left Atrial Appendage Closure Device: The Device Waltz.

Embolization of a device in patients undergoing percutaneous left atrial appendage closure is an uncommon complication. We present an illustrative case of successful percutaneous retrieval of an embolized LAmbre device (Lifetech Scientific, Shenzhen, China) that was achieved with a combination of a snaring technique and forceps grasping and by using a steerable guiding catheter.

Giant pericardial mass case report: role of echocardiography.

Cardiac masses are rare and they are distinguished in tumors and non-tumoral masses. Primary pericardial masses are very rare and they are often asymptomatic, even if they can present with sudden cardiac death. The diagnosis of these masses is often accidental and they are generally identified with echocardiography; their characterization is usually performed by cardiac magnetic resonance imaging (MRI) but the definitive diagnosis is achieved by tissue biopsy.

D-dimer driven deep vein thrombosis prophylaxis strategy for hospitalized patients with COVID-19.

COVID-19 induces a hypercoagulable state with early case reports of death from undetected venous thromboembolism. Various protocols and consensus statements have been proposed to address the optimal prophylaxis strategy for hospitalized patients. We offer our single institution experience with a d-dimer driven prophylaxis model with no deep vein thrombosis identified on discharge lower extremity ultrasounds.
