Top Biologists Call for Moratorium on Use of CRISPR Gene Editing Tool for Clinical Purposes Because of Concerns about Unresolved Ethical Issues

Most pathologists know that CRISPR can permanently repair DNA to eliminate diseases that plague families, but also could be used for less ethical purposes, say experts

Gene editing is a rapidly developing field that is expected to create new diagnostic needs that can be filled by pathologists and by new medical laboratory tests. However, experts in bio-ethics are voicing concerns that gene editing for clinical purposes is moving forward without proper consideration of important ethical issues and are calling for a moratorium on use of gene editing for clinical purposes.

What is speeding the development of gene editing is use of the tool known as CRISPR/Cas9. It is a gene-editing tool that makes it possible to genetically modify DNA for therapeutic purposes. It provides medical scientists the ability to repair damaged genes that cause or predispose individuals to disease. (more…)

Researchers at UC Berkeley Develop Wearable, Disposable Device for Pulse Oximetry with Technology That Could Measure Other Biomarkers In Vivo

This innovative technology platform is newest effort to measure biomarkers without the need for the invasive specimen collection techniques used in medical laboratory testing

Pathologists and clinical laboratory managers interested in how new technologies are transforming certain well-established clinical practices will be interested to learn about the latest research breakthroughs in pulse oximetry, a common procedure used to measure the oxygen level (or oxygen saturation) in the blood.

Pulse oximetry is considered to be a noninvasive, painless, general indicator of oxygen delivery to the peripheral tissues (such as the finger, earlobe, or nose). For decades, PO has been ubiquitous in the hospital. Now, because of recent advance, this field is poised for a paradigm shift away from simple monitoring devices to advanced products capable of connecting patients to electronic systems that continuously gather data and notify caregivers when values become critical.

A group of bioengineering doctoral students at the University of California Berkeley (UC Berkeley) have invented an inexpensive Band-Aid-style oximeter that uses red and green light to non-invasively monitor pulse rate and oxygen level in blood. While this device could revolutionize pulse oximetry monitoring in healthcare settings, the technology might also be applied to measuring other useful biomarkers as one approach to eliminate invasive specimen collection.

Breakthrough DNA Editing Tool May Help Pathologists Develop New Diagnostic Approaches to Identify and Treat the Underlying Causes of Diseases at the Genetic Level

The advent of the CRISPR/Cas9 genetic editing tool is already generating novel therapies for diseases and will create new opportunities for pathologists and medical laboratories

In just 24 months, a new gene-editing tool has become the hot topic worldwide among researchers working to understand DNA and develop ways to manipulate it for therapeutic purposes. It goes by the acronym CRISPR and it may soon become quite familiar to most pathologists and medical laboratory scientists.

CRISPR stands for clustered regularly interspaced short palindromic repeats. The gene editing platform is known as CRISPR/CAS9. (more…)

Stanford Medical Students Undergo Genetic Testing to Study Their Own Genotypes

Pathology departments may want to create similar courses to teach medical students how to interpret genetic and genotyping tests

Genetic testing of participating university students was part of a special class that was conducted at the Stanford University School of Medicine last summer. The genetic pathology test was voluntary for the 54 students who participated in the eight-week course that was designed by a student.

The genotyping happened as part of the class, titled “Genetics-210, Genomics and Personalized Medicine.” It was intended to help medical students learn how to interpret genetic tests, and also to help them gain an understanding of ho learning the results of such tests could affect future patients.
