Leadless pacemaker with transcatheter aortic valve implantation: A single-center experience.

Background: The safety and efficacy of leadless pacemakers (LP) in transcatheter aortic valve implant (TAVI) patients is not well known due to paucity of data. Herein, we compared outcomes between leadless pacemakers to traditional dual chamber pacemakers (DCP) following TAVI.

Methods: A single-center retrospective study was conducted, including a total of 27 patients with LP and 33 patients with DCP after TAVI between November 2013 and May 2021.

Developability profile framework for lead candidate selection in topical dermatology.

The development of molecules for topical dermatology has primarily relied on drug repurposing or on combination therapies, leading to an average of only one New Chemical Entity (NCE) approved per year by the FDA. Topical products offer benefits to patients by enabling localized treatment, while minimizing systemic exposure and the likelihood of adverse events. New therapies are further justified by the burden skin diseases cause on patients' quality of life.

Stimulus-responsive hydrogels: Theory, modern advances, and applications.

Over the past century, hydrogels have emerged as effective materials for an immense variety of applications. The unique network structure of hydrogels enables very high levels of hydrophilicity and biocompatibility, while at the same time exhibiting the soft physical properties associated with living tissue, making them ideal biomaterials. Stimulus-responsive hydrogels have been especially impactful, allowing for unprecedented levels of control over material properties in response to external cues.

Medicaid Contradictions: Adding, Subtracting, and Redeterminations in Illinois.

States are required to conduct annual Medicaid redeterminations. How these redeterminations are undertaken is crucial to determining the nature of Medicaid coverage. There can be wide variations in the proportion of clients disenrolled, with potentially large numbers of people disenrolled each year.

pH-responsive and enzymatically-responsive hydrogel microparticles for the oral delivery of therapeutic proteins: Effects of protein size, crosslinking density, and hydrogel degradation on protein delivery.

Two potential platform technologies for the oral delivery of protein therapeutics were synthesized and tested. pH-responsive poly(itaconic acid-co-N-vinyl-2-pyrrolidone) (P(IA-co-NVP)) hydrogel microparticles were tested in vitro with model proteins salmon calcitonin, urokinase, and rituximab to determine the effects of particle size, protein size, and crosslinking density on oral delivery capability. Particle size showed no significant effect on overall delivery potential but did improve percent release of encapsulated protein over the micro-scale particle size range studied.
