Artificial Intelligence Applications in Clinical Chemistry.

Artificial intelligence (AI) applications are an area of active investigation in clinical chemistry. Numerous publications have demonstrated the promise of AI across all phases of testing including preanalytic, analytic, and postanalytic phases; this includes novel methods for detecting common specimen collection errors, predicting laboratory results and diagnoses, and enhancing autoverification workflows. Although AI applications pose several ethical and operational challenges, these technologies are expected to transform the practice of the clinical chemistry laboratory in the near future.

Clinical Characteristics and Outcomes for 7,995 Patients with SARS-CoV-2 Infection.

Objective: Severe acute respiratory syndrome virus (SARS-CoV-2) has infected millions of people worldwide. Our goal was to identify risk factors associated with admission and disease severity in patients with SARS-CoV-2.

Design: This was an observational, retrospective study based on real-world data for 7,995 patients with SARS-CoV-2 from a clinical data repository.

Health Care and Precision Medicine Research: Analysis of a Scalable Data Science Platform.

Background: Health care data are increasing in volume and complexity. Storing and analyzing these data to implement precision medicine initiatives and data-driven research has exceeded the capabilities of traditional computer systems. Modern big data platforms must be adapted to the specific demands of health care and designed for scalability and growth.

The enthesis: a review of the tendon-to-bone insertion.

The integration of tendon into bone occurs at a specialized interface known as the enthesis. The fibrous tendon to bone enthesis is established through a structurally continuous gradient from uncalcified tendon to calcified bone. The enthesis exhibits gradients in tissue organization classified into four distinct zones with varying cellular compositions, mechanical properties, and functions in order to facilitate joint movement.

In vitro evaluation of the anti-bacterial effect of two preparations of platelet rich plasma compared with cefazolin and whole blood.

Purpose: This study investigates the antibacterial properties of two different platelet-rich plasma (PRP) platelet concentration preparations (PRPLP and PRPHP) through a time-kill assay.

Methods: Two different PRP preparations - a single spin process yielding lower white blood cells and platelet concentration (PRPLP) and one yielding high platelet and white blood cell concentration (PRPHP) - were obtained from 2 individuals. PRPLP, PRPHP, phosphate buffered saline (PBS), whole blood and Cefazolin were added to experimental reaction tubes, each containing a single bacterial inoculum of Staphylococcus aureus (S.
