A new three-minute EEG-based test called the Fastball EEG may enable quick, non-invasive detection of early memory issues related to Alzheimer's disease, potentially allowing for earlier intervention and diagnosis, though further research is needed to confirm its effectiveness across diverse populations.
A new three-minute EEG-based test called the Fastball EEG could enable early detection of Alzheimer's disease by measuring brain responses to images, potentially allowing for earlier intervention and better management of the disease.
A new three-minute EEG-based test called the Fastball EEG test shows promise in quickly identifying early memory issues related to Alzheimer's disease by measuring brain responses to images, potentially enabling earlier diagnosis and intervention.
Scientists have developed a diagnostic test to identify women at increased risk of miscarriage by analyzing the womb lining's reaction, potentially leading to new treatments to prevent pregnancy loss, especially in women with recurrent miscarriages.
UK scientists have developed a test to identify women with abnormal womb lining that increases miscarriage risk, potentially leading to targeted treatments and hope for women experiencing recurrent pregnancy loss, exemplified by a successful case using the drug sitagliptin.
A new test developed by the University of Cambridge can predict whether chemotherapy will be effective for cancer patients by analyzing tumor DNA, potentially allowing for more personalized and effective treatment plans, and reducing unnecessary side effects.
A new diagnostic test developed at UCSF uses DNA sequencing to identify a wide range of pathogens causing illnesses, particularly effective in diagnosing neurological infections like meningitis. Although not FDA-approved and costly, it has shown promise in cases where traditional tests fail. The test, which has a 'breakthrough device' designation, could potentially detect novel viruses and aid in diagnosing complex infections, but its complexity and cost limit widespread use. Researchers aim to reduce costs and improve accessibility for broader hospital use.
A skin biopsy test has shown high accuracy in detecting an abnormal form of alpha-synuclein, the pathological hallmark of Parkinson’s disease and related neurodegenerative disorders. The study, sponsored by the National Institutes of Health, demonstrated the reliability of this cutaneous method as a tool for more accurate diagnoses, potentially offering better care for patients. The research may also aid in accelerating drug development for these complex diseases.
Researchers at the University of Cincinnati have developed an at-home test similar to a lateral flow test for COVID-19 that can diagnose gum disease, or gingivitis, in just 10 minutes. The test involves mixing a saliva sample with a solution containing starch extracted from potatoes, which removes interfering proteins. Antibodies in the solution bind to bacteria associated with gum disease, producing red lines on the test strip. Gum disease has been linked to serious health conditions such as heart disease and dementia, and early detection can lead to interventions that reduce the risk of cardiovascular deaths by 50%.
Liquid biopsy startup AOA Dx has raised $17 million to support the development of its diagnostic test for ovarian cancer, which is based on its GlycoLocate platform. The platform is designed to detect elevated levels of gangliosides, cell signaling molecules often seen in cancer patients. AOA Dx has started a prospective study called OVERT to investigate its first diagnostic test, AKRIVIS GD, for ovarian cancer.
Scientists have made progress in identifying potential biomarkers for long Covid, a condition characterized by lingering symptoms after a coronavirus infection. In a study published in Nature, researchers found consistent immune and hormonal differences in the blood of long Covid patients compared to those who had fully recovered or had no prior infection. Using machine learning, they developed a potential diagnostic algorithm that achieved 96% accuracy in differentiating long Covid patients from controls. Further research is needed to confirm these findings, but this work could lead to the development of reliable blood testing protocols and a better understanding of long Covid.
Researchers have developed a diagnostic test to identify functional sperm in infertile men, particularly those with nonobstructive azoospermia (NOA), potentially revolutionizing treatments in male infertility and assisted reproductive technology. The study identifies two proteins, AKAP4 and ASPX, in intact sperm, and suggests the work could even lead to non-hormonal male contraceptives in the future.
A new, affordable finger-prick diagnostic test developed by Washington State University researcher John Alderete could help combat the prevalent but underdiagnosed sexually transmitted infection, Trichomonas vaginalis. The test delivers results in just five minutes and costs under $20. Trich is easily curable with metronidazole but is often only diagnosed when symptoms are present. Alderete’s test requires only a drop of blood to detect a specific antibody unique to Trich, making it more accessible and user-friendly. The test aims to meet World Health Organization “ASSURED” standards for disease detection, with hopes of benefiting low-resource countries and curbing the spread of the infection.
A new finger-prick test for Trichomonas vaginalis, the most prevalent non-viral sexually transmitted infection, has been developed by a researcher at Washington State University. The test delivers results in five minutes and can be produced for under $20. It requires only a drop of blood to detect an antibody specific to trich and can be administered without specialized training or equipment. The test meets World Health Organization "ASSURED" standards for disease detection and could be particularly useful in low-resource countries where trich is suspected to be a contributing factor in the spread of HIV.
