Physician Experiences With Implementing a Virtual Observation Unit in Emergency Medicine.

Study Objective: Physician experiences with new care models like the virtual observation unit in emergency departments (EDs) can offer important insights. Virtual observation unit leverages telehealth, remote monitoring, and mobile integrated health to enable home-based ED-level care. We explored physicians' experience with delivering care in the virtual observation unit and perceived effect of this new model.

Barriers and facilitators to point-of-care ultrasound use in an academic emergency department by perceived usability.

Background: While use of point-of-care ultrasound (POCUS) has become widespread in emergency medicine, its adoption and usage among emergency clinicians is variable. In this study, we explored the barriers and facilitators to POCUS use among emergency medicine clinicians in a tertiary care emergency department in the United States by clinical role and perceived usability of POCUS.

Methods: We initially administered a quantitative survey via REDCap and used a validated technology usability scale to categorize clinicians into tertiles of low, moderate, and high, based on perceived utility of POCUS.

Thermally Assisted Microfluidics to Produce Chemically Equivalent Microgels with Tunable Network Morphologies.

Although micron-sized microgels have become important building blocks in regenerative materials, offering decisive interactions with living matter, their chemical composition mostly significantly varies when their network morphology is tuned. Since cell behavior is simultaneously affected by the physical, chemical, and structural properties of the gel network, microgels with variable morphology but chemical equivalence are of interest. This work describes a new method to produce thermoresponsive microgels with defined mechanical properties, surface morphologies, and volume phase transition temperatures.

Adsorption of Polycyclic Aromatics on Crystal Surface of Coordination Cages: Photophysical Properties and Förster Resonance Energy Transfer.

Self-assembly reactions of PdX (X = NO, BF, ClO, ReO, PF, and CFSO) with 9,10-bis((isoquinolin-5-yloxy)methyl)anthracene (L) in MeSO give rise to single crystals of coordination cages, [X@PdL]X, irrespective of X anions, in high yields. The intracage PdPd distance is significantly sensitive to the nestled X anion, which can serve as a gauge for recognition of ubiquitous polyatomic anions. One interesting feature is that, via π-π interactions, various polycyclic aromatics (PAs) are characteristically adsorbed on the crystal surface of designed coordination cages with a wall of anthranyl moiety.
