A Novel Polarized Light Microscope for the Examination of Birefringent Crystals in Synovial Fluid.

Background: The gold standard for crystal arthritis diagnosis relies on the identification of either monosodium urate (MSU) or calcium pyrophosphate (CPP) crystals in synovial fluid. With the goal of enhanced crystal detection, we adapted a standard compensated polarized light microscope (CPLM) with a polarized digital camera and multi-focal depth imaging capabilities to create digital images from synovial fluid mounted on microscope slides. Using this single-shot computational polarized light microscopy (SCPLM) method, we compared rates of crystal detection and raters' preference for image.

Electronic Health Literacy among Linguistically Diverse Patients in the Los Angeles County Safety Net Health System.

Background: Electronic health (eHealth) literacy may affect telehealth uptake, yet few studies have evaluated eHealth literacy in underserved populations.

Objective: The objective of this study was to describe technology access and use patterns as well as eHealth literacy levels among English-speaking and LEP patients in a Los Angeles safety net health system.

Methods: Patients, aged ≥18 years with a diagnosis of diabetes mellitus and/or hypertension, and their caregivers were recruited from three primary care safety-net clinics in Los Angeles County (California) between June - July 2017.

Advancing practical usage of microtechnology: a study of the functional consequences of dielectrophoresis on neural stem cells.

The integration of microscale engineering, microfluidics, and AC electrokinetics such as dielectrophoresis has generated novel microsystems that enable quantitative analysis of cellular phenotype, function, and physiology. These systems are increasingly being used to assess diverse cell types, such as stem cells, so it becomes critical to thoroughly evaluate whether the systems themselves impact cell function. For example, engineered microsystems have been utilized to investigate neural stem/progenitor cells (NSPCs), which are of interest due to their potential to treat CNS disease and injury.
