Optical-Based Biosensors and Their Portable Healthcare Devices for Detecting and Monitoring Biomarkers in Body Fluids.

The detection and monitoring of biomarkers in body fluids has been used to improve human healthcare activities for decades. In recent years, researchers have focused their attention on applying the point-of-care (POC) strategies into biomarker detection. The evolution of mobile technologies has allowed researchers to develop numerous portable medical devices that aim to deliver comparable results to clinical measurements.

Young Adult African American family members' perceptions, knowledge, attitudes, and utilization toward advance directives.

Advance directives (ADs) give patients autonomy in making decisions regarding end-of-life preferences prior to becoming incapacitated or otherwise unable to communicate. Limited family-related research currently exists on young, adult African American families and their knowledge, attitudes, and perceptions toward the utilization of ADs. A mixed-method design of quantitative data, using the Advance Directives-Knowledge, Attitudes, and Utilization Questionnaire (AD-KAUQ); and qualitative data, using a focused group session, was conducted in a southeastern city in the United States.
