Systems Analysis of a Dedicated Ambulatory Respiratory Unit for Seeing and Ensuring Follow-up of Patients With COVID-19 Symptoms.

COVID-19 necessitated significant care redesign, including new ambulatory workflows to handle surge volumes, protect patients and staff, and ensure timely reliable care. Opportunities also exist to harvest lessons from workflow innovations to benefit routine care. We describe a dedicated COVID-19 ambulatory unit for closing testing and follow-up loops characterized by standardized workflows and electronic communication, documentation, and order placement.

Initial diagnosis of insignificant cancer, high-grade prostatic intraepithelial neoplasia, atypical small acinar proliferation, and negative have the same rate of upgrade to a Gleason score of 7 or higher on repeat prostate biopsy.

Extended prostate needle core biopsies are standard of care for the diagnosis of prostatic carcinoma. Subsequent biopsies may be performed for a variety of indications. Knowledge of biopsy characteristics indicating risk for progression may have utility to guide therapeutic management.

Urologist's Impact on Needle Core Prostate Biopsy Histopathologic Variables Within a Single Institution.

Objective: To assess the urologist's impact on prostate needle core biopsy variables including number of containers submitted, total core length, longest core length, and individual core length threshold values, and to elucidate the relationship between these variables and cancer detection rate within a recent cohort.

Methods: A retrospective search was performed to identify patients who had an extended transrectal ultrasound-guided prostate needle core biopsy between 2008 and 2013.

Results: One thousand one prostate biopsies were analyzed.

Accurate in situ measurement of complex refractive index and particle size in intralipid emulsions.

A first accurate measurement of the complex refractive index in an intralipid emulsion is demonstrated, and thereby the average scatterer particle size using standard Mie scattering calculations is extracted. Our method is based on measurement and modeling of the reflectance of a divergent laser beam from the sample surface. In the absence of any definitive reference data for the complex refractive index or particle size in highly turbid intralipid emulsions, we base our claim of accuracy on the fact that our work offers several critically important advantages over previously reported attempts.
