Nanostructured drug delivery systems for posterior segment eye diseases: Strategies to defy ocular barriers

BMEMat, EarlyView.
Efficient drug delivery to the posterior segment of the eye has long been a challenging issue due to the complex ocular barriers. The review focuses on the promise held by nanoplatforms for barrier penetration and the key mechanisms involved, also highlighting their advantages in achieving efficient drug delivery and superior treatment of PSEDs ...

Management of Lost Atherectomy Devices in the Coronary Arteries

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Rotational and orbital atherectomy are important tools to treat calcific coronary disease. Entrapment of an atherectomy device, that is, rotational atherectomy burr or orbital atherectomy crown, is a serious complication during atherectomy. Loss of an atherectomy device is a more challenging complication that usually follows device entrapment.

Minimum Lumen Area Indexed to Left Ventricular Mass to Identify Functionally Significant Left Main Coronary Stenoses

Catheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background and Aim Diagnosing significant left main coronary artery (LMCA) stenoses based on anatomical criteria remains challenging. The ARMYDA FINISH multicenter study evaluated whether indexing intravascular ultrasound (IVUS)‐derived minimum lumen area (MLA) provides greater diagnostic accuracy than unindexed MLA for detecting ...
