Researchers from Rowan University & Durin Technologies Announce Highly Accurate Blood Test for Alzheimer’s Disease
A blood test focusing on a set of eight autoantibody markers was 97% effective in detecting the presence of Alzheimer’s disease-related pathology up to 10 years before onset of clinical symptoms. According to the investigators, “this is the first blood test to accurately detect Alzheimer’s-related pathology several years before either clinical symptoms or more expensive and invasive tests can identify the disease.”

Study Highlights Prevalence of Buprenorphine “Spiking” in Urine Screenings for OUD Patients
Originally published in JAMA Psychiatry, a broad-based study shows nearly 7% of OUD patients are adding buprenorphine to urine sample to fake treatment adherence. Buprenorphine spiking suggests to the physician that the treatment plan is not working—especially in patients continuing illicit drug use.

EasyM, Blood Test for Residual Myeloma Activity, Certified in US
The article reports that a new blood test, called the EasyM protocol, has been certified by the US Food and Drug Administration (FDA) for use in detecting multiple myeloma relapse. The test works by detecting small amounts of circulating tumor DNA (ctDNA) in the blood, which can indicate the presence of residual disease. The EasyM protocol is reportedly more sensitive than existing tests for detecting ctDNA, and can provide results in just a few hours. The article notes that the test has the potential to improve patient outcomes by allowing for earlier detection of relapse and more personalized treatment options.

FDA Clears Lab-Based Blood Test to Aid in Concussion Assessment
The Abbott Alinity I TBI test is a laboratory-based test that measures ubiquitin C-terminal hydrolase L1 (UCH-L1) and glial fibrillary acidic protein, two biomarkers in the blood that have been linked to brain injury when present in high concentrations. The test has a sensitivity of 96.7% and a negative predictive value of 99.4%. The availability of a blood test provides clinicians with an objective method to quickly evaluate patients with mTBIs while eliminating the need for a head CT scan, potentially reducing health care costs and minimizing emergency department wait times.

MKSAP Quiz: Evaluation for Sports Participation
The patient’s blood pressure is 110/70 and his pulse is 52. Cardiac auscultation is normal. BMI is 22. The ECG shows sinus bradycardia and voltage criteria for LVH. The QT interval is 400 ms, and there is early repolarization. Review the details of the ECG and echo and determine your diagnosis.
