99 Problems but They’re All Causally Related: Multiple Independent, Symptomatic Conditions are Rarely Diagnosed
Doctors must balance trying to find one diagnosis that explains all of a patient’s symptoms, and acknowledging that multiple conditions can co-occur. The authors sought to better understand multiple diagnoses by reviewing case reports. Multiple diagnoses usually involved cases in…
Bridging the chasm between technology and clinicians
While the use of artificial intelligence (AI) for medical diagnosis is growing, new research by the University of Adelaide has found there are still major hurdles to cover when compared to a clinician. In a paper published in The Lancet Digital Health, Australian Institute for Machine Learning PhD student Lana Tikhomirov, Professor Carolyn Semmler and team from the University of Adelaide, have drawn on external research to investigate what’s known as the ‘AI chasm’.

Video and Transcript Available – FDA Changes to Laboratory Developed Test Regulation: Livestreamed Expert Panel
Live from the annual conference of the Association for Diagnostics & Laboratory Medicine (ADLM, formerly AACC), experts will discuss how the new FDA rule on laboratory developed tests will hinder patient care. This rule will place these tests under duplicative FDA oversight, even though laboratory developed tests are already regulated by the Centers for Medicare & Medicaid Services. This will force many labs to stop performing these essential tests, which play a critical role in diagnosing rare disorders, such as inherited genetic conditions in newborns.

Prenatal alcohol exposure (PAE) is a known cause of birth and growth defects and neurobehavioral issues.
Point-of-Care Biosensor Rapidly Detects Oral Cancer
Since oral cancer occurs in one of the most accessible sites in the body, it can be easily treated if detected promptly. In Journal of Vacuum Science & Technology B, researchers report a breakthrough hand-held biosensor that enables quick and accurate detection of oral cancer. The group’s biosensor consists of a sensor strip, similar to a glucose strip, and a circuit board (a hand-held terminal like a glucometer) for detection.
Machine Learning Diagnoses Pneumonia by Listening to Coughs #ASA183
Researchers have developed a machine learning algorithm to identify cough sounds and determine whether the subject is suffering from pneumonia. Because every room and recording device is different, they augmented their recordings with room impulse responses, which measure how the acoustics of a space react to different sound frequencies. By combining this data with the recorded cough sounds, the algorithm can work in any environment.

Study Identifies Concerning Delays in TB Diagnoses in the United States
Most delays ranged between 10 and 45 days, with a median of 24 days, after a visit to a doctor, which exceeds current World Health Organization recommendations of diagnosing and treating TB within two to three weeks of symptom onset
Delays were linked to greater risk for disease complications, transmission of infection to household members
Older individuals and those with compromised immunity were at greater risk for delayed diagnoses
Use of diagnostic molecular testing, use of chest imaging and being seen by a specialist were all linked to more prompt identification of TB infection, suggesting delays may be preventable
Findings underscore the need to increase awareness of TB among frontline clinicians who may not suspect TB due to rarity of infection in this country
UCLA seeks volunteers for study of COVID-19’s impact on health to support “longhaul” survivors
UCLA researchers are seeking participants for an innovative study examining the impact of COVID-19 on survivors who continue battling health issues long after they were infected and thought to have recovered, known informally as “long COVID” and “longhaulers.”
Rethinking Race and Kidney Function
Removing race from clinical tools that calculate kidney function could have both advantages and disadvantages for Black patients.
Newly diagnosed patients and those whose kidney disease is reclassified as more severe would have greater access to kidney specialists, faster access to the kidney-transplant waitlist.
On the flipside, patients reclassified as having more severe kidney disease may become ineligible for heart, diabetes, pain control and cancer medications or may be given lower doses for these drugs.
A new kidney function score would also increase the number of Black individuals ineligible to donate a kidney, potentially exacerbating organ shortages for Black people.
Researchers caution that clinicians and policy makers must anticipate both the benefits and downsides of changes to the current formula to ensure that Black patients are not disadvantaged, and
health disparities are not exacerbated.
Scientists say the analysis should motivate researchers and cl

New Machine Learning Tool Predicts Devastating Intestinal Disease in Premature Infants
Researchers from Columbia Engineering and the University of Pittsburgh have developed a sensitive and specific early warning system for predicting necrotizing enterocolitis (NEC) in premature infants before the life-threatening intestinal disease occurs. The prototype predicts NEC accurately and early, using stool microbiome features combined with clinical and demographic information. “The lessons we’ve learned from our new technique could well translate to other genetic or proteomic datasets and inspire new machine learning algorithms for healthcare datasets.”
Doctors motivated by both health, malpractice concerns when ordering additional tests
A UCLA-led study has found that dermatopathologists, who specialize in diagnosing skin diseases at the microscopic level, are motivated both by patient safety concerns and by malpractice fears — often simultaneously — when ordering multiple tests and obtaining second opinions, with a higher proportion of these doctors reporting patient safety as a concern.
When ordering additional microscopic tests for patients, 90% of the dermatopathologists surveyed cited patient safety as a concern and 71% of them reported malpractice fears. Similarly, when obtaining second reviews from a consulting pathologist or recommending additional surgical sampling, 91% cited safety concerns and 78% malpractice concerns.
Researchers Identify Distinct Subtypes of Polycystic Ovary Syndrome With Novel Genetic Associations

LLNL providing critical assistance in addressing national swab shortage for COVID-19 testing
To address the nationwide shortage of specialized nasal swabs used for COVID-19 diagnoses, Lawrence Livermore National Laboratory engineers formed an ad hoc, rapid response team that tested more than a dozen novel, 3D-printed swab designs from a grassroots coalition of commercial and academic partners. The mechanical tests performed at the Lab provided valuable feedback that improved the designs, enabling them to meet requirements for COVID-19 testing. The Lab’s work on swabs is continuing with funding from the U.S. Department of Energy (DOE) and expanding into other 3D-printed components for COVID-19 test kits.
Rutgers Launches Genetic Testing Service for New Coronavirus

Duchenne Muscular Dystrophy Diagnosis Improved by Simple Accelerometers
Testing for Duchenne muscular dystrophy can require specialized equipment, invasive procedures and high expense, but measuring changes in muscle function and identifying compensatory walking gait could lead to earlier detection. This week in Chaos, researchers present a relative coupling coefficient, which can be used to quantify the factors involved in the human gait and more accurately screen for the disorder. They measured movements of different parts of the body in test subjects, viewing the body as a kinematic chain.

Expanding Medicaid means chronic health problems get found & health improves, study finds
Nearly one in three low-income people who enrolled in Michigan’s expanded Medicaid program discovered they had a chronic illness that had never been diagnosed before, according to a new study.
And whether it was a newly found condition or one they’d known about before, half of Medicaid expansion enrollees with chronic conditions said their overall health improved after one year of coverage or more.
