Cardiovascular disease encompasses coronary artery disease and valvular heart disease, and the prevalence of both increases with age. Over the past decade, the landscape of interventional cardiology has evolved to encompass a new set of percutaneous procedures outside the coronary tree, including transcatheter aortic valve implantation, transcatheter mitral valve repair, and left atrial appendage occlusion. These interventions have sparked a new discipline within interventional cardiology referred to as structural heart disease (SHD) intervention...

The conflict in Syria presents new and unprecedented challenges that undermine the principles and practice of medical neutrality in armed conflict. With direct and repeated targeting of health workers, health facilities, and ambulances, Syria has become the most dangerous place on earth for health-care providers. The weaponisation of health care-a strategy of using people's need for health care as a weapon against them by violently depriving them of it-has translated into hundreds of health workers killed, hundreds more incarcerated or tortured, and hundreds of health facilities deliberately and systematically attacked...

It is unclear whether warfarin is protective or harmful in patients with ESRD and atrial fibrillation. This state of equipoise raises the question of whether alternative anticoagulants may have a therapeutic role. We aimed to determine apixaban pharmacokinetics at steady state in patients on hemodialysis. Seven patients received apixaban 2.5 mg twice daily for 8 days. Blood samples were collected before and after apixaban administration on days 1 and 8 (nondialysis days). Significant accumulation of the drug was observed between days 1 and 8 with the 2...

Root-knot nematodes are soil-borne pathogens that invade and establish feeding sites in plant roots. They have an extremely broad host range, including most vascular plants. During infection of a susceptible host, root-knot nematodes secrete molecules called effectors that help them establish an intimate interaction with the plant and, at the same time, allow them to evade or suppress plant immune responses. Despite the fact that Meloidogyne hapla is a significant pest on several food crops, no effectors have been characterized from this root-knot nematode species thus far...

INTRODUCTION: As the inter-relationships of objectively-ascertained sleep disordered breathing (SDB), post-cardiac surgery atrial fibrillation (PCSAF) and obesity remain unclear; we aimed to further investigate in a clinic-based cohort. METHODS: Patients with polysomnography (PSG) and cardiac surgery (coronary artery bypass surgery and/or valvular surgery) within 3 years, from January 2009 to January 2014 were identified excluding those with pre-existing AF. Logistic models were used to determine the association of SDB (apnea hypopnea index (AHI) per 5 unit increase) and secondary predictors [central sleep apnea (CSA) (central apnea index>5) and oxygen desaturation index (ODI)] with PCSAF...

Perioperative pancreatitis is a significant comorbid condition in surgical patients, however the degree to which pancreatitis affects graft and overall survival in liver transplant recipients has not been evaluated. This study assesses the impact of pancreatitis on graft and patient survival in adult orthotopic liver transplantation (OLT). All patients undergoing OLT at a single academic institution from 2007-2015 were reviewed. Pancreatitis was classified by method of diagnosis (intra-operative or radiographic (IO/R) versus isolated serologic (IS)) and timing (pre-operative versus post-operative)...

Quantum dots (QDs) and upconverting nanoparticles (UCNPs) are luminescent nanoparticles (NPs) commonly used in bioassays and biosensors as resonance energy transfer (RET) donors. The narrow and tunable emissions of both QDs and UCNPs make them versatile RET donors that can be paired with a wide range of acceptors. Ratiometric signal processing that compares donor and acceptor emission in RET-based transduction offers improved precision, as it accounts for fluctuations in the absolute photoluminescence (PL) intensities of the donor and acceptor that can result from experimental and instrumental variations...
