Diagnosing SARS-CoV-2

The arsenal: Molecular (PCR), antigen and antibody testing

Germany’s lack of diagnostic ability led to significantly underestimation of its own as well as global Covid-19 infection levels during the first wave. Now, however, improved testing and diagnosis of the condition more realistically reveal nearer 20,000 new cases a day across the country, according to Professor Hendrik Streeck, one of the country’s leading virologists. Speaking at a virtual…

Profiling the coronavirus

Experts unlock Covid-19 secrets

Experts have identified two distinct immunological and cellular profiles in the lungs of Covid-19 patients which they believe could help define treatment pathways. From some of the earliest Covid-19 autopsies conducted in Europe, Swiss-based researchers have performed integrative digital pathology and transcriptomic analyses of lung tissues of 16 coronavirus patients who died from respiratory…

Using virus particles in exhaled breath

New SARS-CoV-2 test to deliver results in under 5 minutes

Research and innovation hub Imec announced that it has started developing a groundbreaking SARS-CoV-2 test. Unlike current approaches (using blood, saliva, or a nasopharyngeal swab), the new test will identify SARS-CoV-2 virus particles in a person’s exhaled breath. The solution promises the accurate identification of a contagious case in less than five minutes.

Digital pathology: Luxury or necessity?

The anatomical pathologist faces a crisis. Public and private labs suffer increasing caseloads, whilst pathologist numbers diminish for various reasons, including greater cancer prevalence associated with aging populations as well as improved cancer screening programs. Precision medicine typically involves more genetic testing and extensive use of immunohistochemistry to classify cancer and…

Overcoming the barriers to AI in digital pathology

‘You can’t do AI on glass slides’

As Artificial Intelligence continues to impact on the development of digital pathology, potential users are still slow to implement key enabling technologies to harness the benefits, according to Dr David McClintock, who will detail critical steps for pathology departments to transition practice from glass (analogue) to digital (whole slide imaging) and embrace AI, to the 6th Digital Pathology…

High-capacity digital image analysis

Spatial statistics extract subvisual features

Spatial analytics offers greater clarity in the assessment of tumours beyond routine microscopic analysis. High-capacity digital image analysis enables new methods of spatial statistics to extract features not immediately distinguishable by visual inspection. These subvisual features reflect complex properties, such as intratumour heterogeneity and have the additional benefit that they can target…

Tissue analysis

Infrared spectroscopy as a diagnostic tool

New techniques of infrared-based technology are showing strong potential for cost-effective tissue analysis. Peter Gardner, Professor of Analytical and Biomedical Spectroscopy at the University of Manchester, outlined how hyperspectral imaging coupled with sophisticated computer algorithms can identify and grade cancerous tissue, as well as offer an indication of prognosis. The technique, he…

How digital pathology is shaping the future of precision medicine

In recent years, technological and regulatory advances have made digital pathology a viable alternative to the conventional microscope. The obtention of a digital replica of the traditional glass slide and its use for primary diagnosis has revolutionized pathology and is shaping the future of the discipline. A digital pathology lab uses digital histology slides for routine diagnosis, and these…

Pathological regression of lymph nodes

Improved grading system to predict esophageal cancer survival

A group of researchers led by Osaka University established a new pathological grading system to evaluate the therapeutic effect of neoadjuvant chemotherapy (NAC) for metastatic lymph nodes (LNs) removed in esophageal cancer (EC) surgery, demonstrating that the system predicts recurrence and prognosis in EC patients better than conventional systems. Their research results were published in Annals…

VIPR: Deep learning for small cohorts

To investigate rare diseases, applying image-based analytics approaches, including the use of deep learning convolutional neural networks (DL-CNNs), can be a major challenge due to great difficulties in acquiring sufficient numbers of cases and associated digital image sets from the small cohorts typically available. To realise algorithms that are both effective and generalisable, conventional…

Spreading quality pathology in Canada

Building a telepathology network

Following success of telepathology in the eastern region of Quebec, the service is set to be further expanded across its remote areas. There are also moves towards a fully digital service at some sites, to introduce tele-autopsy into remote regions and extend the geographical coverage further across the region. The latest developments were outlined at the Digital Pathology and AI Congress in…

COVID-19 antibody tests: Not a game-changer after all?

A group of senior clinical academics and physicians are concerned about the rapid roll out of COVID-19 antibody testing in England and are publicly questioning how good the tests are - or even what they mean. In a letter to The BMJ, they argue that there is currently no valid clinical reason for large scale testing, test performance has not yet been adequately assessed, and testing risks…

Lymph node analysis to hunt down metastases

What makes tumor cells turn murderous? The Fraunhofer Institute for Toxicology and Experimental Medicine ITEM is investigating the mechanisms of metastasis formation – and searching for approaches for new treatments in the fight against cancer. Among other things, the research team at Fraunhofer ITEM has developed a method that enables them to analyze entire lymph nodes.

Deep learning accurately stains digital biopsy H&E slides

Tissue biopsy slides stained using hematoxylin and eosin (H&E) dyes are a cornerstone of histopathology, especially for pathologists needing to diagnose and determine the stage of cancers. A research team led by MIT scientists at the Media Lab, in collaboration with clinicians at Stanford University School of Medicine and Harvard Medical School, now shows that digital scans of these biopsy…
