Systematic review finds that machine learning models for detecting and diagnosing Covid-19 from medical images have major flaws and biases, making them unsuitable for use in patients. However, researchers have suggested ways to remedy the problem. Researchers have found that out of the more than 300 Covid-19 machine learning models described in scientific papers in 2020, none of them is suitable…
It is possible to identify Parkinson’s Disease based on compounds found on the surface of skin, according to new research. The findings offer hope that a pioneering new test could be developed to diagnose the degenerative condition through a simple and painless skin swab. Scientists at The University of Manchester have developed a technique which works by analysing compounds found in sebum -…
A new study carried out by a team of laser physicists, molecular biologists and physicians based at LMU Munich and the Max Planck Institute for Quantum Optics has confirmed the temporal stability of the molecular composition of blood in a population of healthy individuals. The data provide a basis for a new method of monitoring the constituents of blood and detecting alterations that reveal…
Researchers at TU Berlin and Charité – Universitätsmedizin Berlin as well as the University of Oslo have developed a new tissue-section analysis system for diagnosing breast cancer based on artificial intelligence (AI). Two further developments make this system unique: For the first time, morphological, molecular and histological data are integrated in a single analysis. Secondly, the system…
Digital Covid-19 ‘symptom checkers’ may stop some patients from getting prompt treatment for serious illness, suggests an international case simulation study. Both the US and UK symptom checkers consistently failed to identify the symptoms of severe Covid-19, bacterial pneumonia, and sepsis, frequently advising these cases to stay home, the findings indicate. The availability and use of…
Beta-glucan tests are proving to be pivotal in the better detection and diagnosis of fungal infections. As a robust complimentary test for traditional testing techniques and biomarkers, it is helping clinicians deliver rapid results and offering greater reassurance in more accurately identifying such infections. β-glucan testing, which is an in vitro diagnostic test, is regularly used at…
The PCR test is the most accurate tool to identify SARS-CoV-2. However, valid results are often available only after days. Moreover, the laboratory must be well equipped, have trained personnel and sufficient financial resources. All of this is usually a problem in Africa. A portable suitcase could help. In cooperation with several African universities, scientists at Leipzig University have found…
A way of using machine learning to more accurately identify patients with a mix of psychotic and depressive symptoms has been developed by researchers at the University of Birmingham. Patients with depression or psychosis rarely experience symptoms of purely one or the other illness. Historically, this has meant that mental health clinicians give a diagnosis of a ‘primary’ illness, but with…
In order to detect the Corona virus SARS-CoV-2, there are further methods of diagnosis apart from the globally used PCR tests (Polymerase chain reaction): The infection can also be recognised on CT scans – for which Artificial Intelligence (AI) can be used as well. An AI system can not only filter CT scan of Covid-19 patients from a data set, but also estimate, which areas of the image are of…
Prostate cancer is one of the most common cancers among men. Patients are determined to have prostate cancer primarily based on PSA, a cancer factor in blood. However, as diagnostic accuracy is as low as 30%, a considerable number of patients undergo additional invasive biopsy and thus suffer from resultant side effects, such as bleeding and pain.
Clinical diagnostics company Beckman Coulter launched its Access SARS-CoV-2 IgG II assay in countries accepting the CE Mark. The new Access SARS-CoV-2 IgG II assay quantitatively measures a patient’s level of antibodies in response to a previous SARS-CoV-2 infection. The ability to establish a quantitative baseline to evaluate an individual’s immune response to the SARS-CoV-2 virus allows…
The 2020 AACC Annual Scientific Meeting & Clinical Lab Expo is just around the corner, and this year, we are going virtual! At Mindray, we are dedicated to empowering TRUST through technology, innovation, and commitment to the advances of science in the in-vitro diagnostics field. Join our virtual community now, and explore Mindray’s reliable solutions trusted by laboratories worldwide. You…
An Artificial Intelligence test has been shown to be able to rapidly screen patients arriving in Emergency Departments for Covid-19, using clinical information routinely available within the first hour of coming to hospital. Results of the CURIAL study, published in The Lancet Digital Health, show that the AI test correctly predicted the Covid-19 status of 92.3% of patients coming to Emergency…
Infertility has long been attributed to women alone, but medical advances have shown it really is a couple’s problem, with 20% of couples presently having trouble conceiving. Medical imaging, in particular ultrasound, can help identify underlying causes of men’s infertility and other related health issues, an Italian radiologist explained during the last European Congress of Radiology.
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…
For a slow-growing microbe that multiplies infrequently, Mycobacterium tuberculosis, the pathogen that causes tuberculosis (TB) has long puzzled researchers as to how it develops resistance to antibiotics so quickly, in a matter of weeks to months.
Siemens Healthineers announced its SARS-CoV-2 IgG Antibody Test (sCOVG) has proven to measure neutralizing antibodies and has achieved CE Mark. The test is an enhanced version of the assay which became available globally this summer. It demonstrates the ability to detect neutralizing antibodies and reports quantitative results measuring the amount of neutralizing antibodies present in a patient's…
In early 1990, at Analytica, in Munich, a young US-American researcher Kary B Mullis received the award for biochemical analytics for his 1983 invention: the polymerase chain reaction (PCR) – a success topped in 1993 by the Nobel Prize for chemistry. Mullis’ work revolutionised DNA copying, a process which, before PCR, had taken weeks. Whilst initially PCR was used to create digital…
In order to analyze tumors, they have to be cut into thin slices. Now, a new technology has been developed that makes pieces of the tumor visible in 3D without cutting them.
Merck announced a collaboration with Mammoth Biosciences Inc. for the development, scale-up and commercial production of Mammoth’s CRISPR-based SARS CoV-2 diagnostic test.
Siemens Healthineers is debuting its new fluoroscopy system, the Luminos Lotus Max, at the annual French JFR 2020 (Journées Francophones de Radiologie Diagnostique & Interventionnelle). The system offers industry-leading technology in radiography and fluoroscopy. “Combining these state-of-the-art technologies poses one major challenge: ensuring efficient workflows and high system…
There are many reasons why for some patients a visit to the doctor’s office is difficult or well-nigh impossible – limited mobility after surgery, old age, or a handicap. For others, particularly in rural areas, the doctor is often far away and/or difficult to reach due to poor public transport. In times of corona, another important issue emerged: infection protection.
A recent preprint study in France underpins the debate on whether lung ultrasound (LUS) should be used to triage COVID-19 patients better at the hospital as well as in primary care. The eChoVid study, published as a preliminary report of work on medTrix, shows that LUS enables identification of lung lesions as well as chest CT in COVID-19 patients. A team of French researchers compared routinely…
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…
