LONDON – Three large scale population surveys conducted between late June and the end of September have shown the prevalence of SARS-CoV-2 antibodies in England declined by 26.5% over three months. The findings rest on the results of more than 350,000 self-administered lateral flow blood tests that were carried out at home by volunteers who were randomly selected from general practitioner registers.

Day Zero Diagnostics Inc. has reported that data presented at IDWeek highlighted the promise of the company’s new class of diagnostics as it works toward its goal of detecting superbug infections quickly. The company ultimately is hoping to get regulatory signoffs in both the U.S. and Europe for its technology.

A new tool for mobile devices can diagnose stroke as accurately as an emergency medicine specialist in just minutes, enabling patients to get brain-saving therapies in time for maximum benefit. According to researchers from Pennsylvania State University and Houston Methodist Hospital, the artificial intelligence (AI)-based tool could counterbalance physician biases, reducing both overuse of CT scans and underdiagnosis of mild and moderate stroke.

Aidoc Inc., a provider of artificial intelligence (AI) solutions in radiology, has won U.S. FDA clearance to market the first software solution for flagging and triaging incidental pulmonary embolism (PE). The AI technology, which includes triaging and notification algorithms, is an “always on” technology that analyzes chest CT scans in real time and alerts the radiologist to any potentially abnormal findings – possibly speeding up diagnosis by hours.

Bluestar Genomics Inc. identified DNA-based epigenomic changes that could be used as new biomarkers that can detect pancreatic cancer before the malignancy, one of the deadliest of all cancers, becomes untreatable. The study was published in Nature Communications.

Abbott Laboratories saw improvement with its medical devices and diagnostics in the third quarter, which featured wins in the areas of COVID-19, diabetes, and structural heart. The company revealed its quarterly results on a Oct. 21 call, during which management said it was increasing its guidance for full-year adjusted earnings per share (EPS) to at least $3.55.

The U.S. FDA cleared Ezra AI Inc.'s artificial intelligence (AI) system for prostate cancer and its cloud-based picture archiving and communication system (PACS) that enables radiologists to use the Prostate AI from their browser. The New York-based company’s Prostate AI is the first prostate-focused artificial intelligence system to gain clearance. The Prostate AI accurately quantifies prostate volume, lesion size, and renders 3D volumes of the prostate gland and lesions.

The U.S. FDA’s device center has declared it will not review emergency use authorization (EUA) requests for lab-developed tests (LDTs) for the COVID-19 pandemic, but on the agency’s most recent town hall, on Oct. 14, FDA officials were uncertain as to whether labs should file those EUAs, leaving labs in a state of limbo yet again.

Nec Corp.’s bioinformatics subsidiary Nec Oncoimmunity AS said it is working with Oslo University Hospital to develop an artificial intelligence (AI) platform that will allow the team to design a T-cell diagnostic to complement the current serological tests for infectious diseases, including COVID-19.
