A blood test to diagnose 50 types of cancer
The Galleri test is a game-changing diagnostic technique far more efficient than other tests. It tests circulating tumor or cell-free DNA in patients' blood samples using next-generation DNA sequencing techniques. The test detects cancer and where it likely started with 90% accuracy. A positive test should be followed by a CT scan or ultrasound to verify the results.
An ingestible sensor could help improve gut research
A battery-free, non-toxic, self-powered, pill-shaped sensor device that runs on biofuel glucose could improve understanding of gut metabolite composition. The device can improve glucose monitoring by producing continuous results, diagnose several diseases, prevent obesity, and study nutrition. The "smart pill" could also help save costs significantly.

AAP releases a list of 5 common conditions seen in kids in ED
The evidence-based list aims at avoiding unnecessary tests, radiation exposure, pain, costs, and prolonged stay in the ED. Radiographs are not needed for croup, asthma, bronchiolitis, first-time wheezing, and constipation, while labs are not required for medical clearance of kids requiring psychiatric admission. Head CT is not needed for generalized and unprovoked seizures.

A simple urine test could diagnose Alzheimer's disease
A study proposed a urine test to detect AD based on formic acid levels. Formaldehyde plays a role in memory and learning, and high levels of formaldehyde could cause cognitive deficits. Formic acid, a metabolic product of formaldehyde, was found in low levels in people with healthy brains. Formic acid combined with other biomarkers increased AD diagnosis accuracy.
Biomarker for primary tauopathies identified
Tauopathies refer to rare brain diseases characterized by rapidly worsening issues with movement and thinking. They are not easy to distinguish from other brain diseases due to similar symptoms. Researchers now found a biomarker for a tauopathy called corticobasal degeneration. Microtubule binding region (MTBR)-tau 275 and MTBR-tau 282 were 89% accurate, as per a study.
Lung cancer screening programs improve the survival of lung cancer patients
Screening people for lung cancer using low-dose CT improved the 20-year survival of lung cancer patients by almost 80%, as per a study. However, only 16% of patients with lung cancer had a diagnosis at an early stage. Also, less than 6% of people eligible for an early screening get it. These findings highlight the benefits of annual screening programs.
One million cancer diagnoses were missed during the COVID-19 pandemic
European experts are warning about an imminent cancer epidemic unless steps are taken to curb it and boost treatment. They believe the impact of the pandemic could set back cancer treatment and outcomes by nearly a decade. The missed diagnosis can cause diagnoses at later stages, increasing the burden on the healthcare system and reducing patient survival and quality of life.
Race may determine the heart disease risk indicated by cholesterol levels
A recent study showed that lower levels of HDL or good cholesterol were tied to a higher risk of heart issues in the long term, only in white people. In contrast, the lower HDL levels were not linked to a higher risk of heart issues in Black people. Moreover, higher HDL levels, which are believed to be protective, were not tied to lower heart disease risk in both races.
FDA authorizes a monkeypox diagnostic test from Roche
The test detects DNA of the monkeypox virus from the swab samples collected from patients with suspected infection. These tests will be available on the Swiss company's cobas systems. These systems can also detect hepatitis B and C and HIV infections. The testing will only be limited to labs meeting the requirements to conduct these complex tests, as per the report.
A touch-based technology could help us know what is happening in the body
Researchers developed a "cryptographic bio-human machine interface" using hydrogel-coated sensors for the collection and detection of circulating compounds on the skin. The technology can also measure blood oxygen levels and heart rate. It also encrypts the data to make it private and secure. This technology is believed to revolutionize noninvasive diagnostics.
