COPD: Biomarker for kidney disease has unexpected benefits

A commonly used biomarker of kidney disease may also indicate lung problems, particularly COPD, or chronic obstructive pulmonary disease, according to new research published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine. In “Albuminuria, Lung Function Decline, and Risk of Incident COPD: the NHLBI Pooled Cohorts Study,” Elizabeth C.…

Noninvasive brain tumor biopsy on the horizon

Taking a biopsy of a brain tumor is a complicated and invasive surgical process, but a team of researchers at Washington University in St. Louis is developing a way that allows them to detect tumor biomarkers through a simple blood test. Hong Chen, a biomedical engineer, and Eric C. Leuthardt, MD, a neurosurgeon, led a team of engineers, physicians and researchers who have developed a…

Novel biomarker test accurately predicting high-grade prostate cancer

ProteoMediX AG announced results from a retrospective study that showed the correlation of its prostate cancer diagnosis test with cancer aggressiveness in patients scheduled for prostate biopsies. The study findings presented at the 2018 European Association of Urology (EAU) congress in Copenhagen, Denmark showed that the test has the potential to avoid a large number of biopsies. “Correlation…

Nanotechnology detects molecular biomarker for osteoarthritis

For the first time, scientists at Wake Forest Baptist Medical Center have been able to measure a specific molecule indicative of osteoarthritis and a number of other inflammatory diseases using a newly developed technology. This preclinical study used a solid-state nanopore sensor as a tool for the analysis of hyaluronic acid (HA). HA is a naturally occurring molecule that is involved in tissue…

A new hope for Alzheimer's prediction

New information on dementia biomarkers is emerging, as increasing results from population studies become available. However, although the list of risk factors lengthens, the value of these predictors, and more generally the cause of disease, remain to be determined, according to Gabriel Krestin, professor and chairman of the Department of Radiology & Nuclear Medicine at Erasmus MC, University…

New prostate cancer risk model could better guide treatment

One of the biggest challenges in treating prostate cancer is distinguishing men who have aggressive and potentially lethal disease from men whose cancer is slow-growing and unlikely to metastasize. For years, prostate-specific antigen (PSA) level, cancer grade and tumor stage have been used to sort prostate cancer patients into risk groups established by the National Comprehensive Cancer Network.…

Single blood test screens for 8 cancer types

Johns Hopkins Kimmel Cancer Center researchers developed a single blood test that screens for eight common cancer types and helps identify the location of the cancer. The test, called CancerSEEK, is a unique noninvasive, multianalyte test that simultaneously evaluates levels of eight cancer proteins and the presence of cancer gene mutations from circulating DNA in the blood. The test is aimed at…

Researchers are developing a ‘Lab-on-skin’ to monitor biomarkers

Move over, lab-on-a-chip and lab-on-paper. There’s a new diagnostic technology in research labs that is gaining credibility. It is called lab-on-skin technology and some scientists are quite excited about how it might be used for a variety of clinical purposes. A recent story published in ACS Nano titled, “Lab-on-Skin: A Review of Flexible and Stretchable Electronics for Wearable Health…

New marker detects fatal breast cancer earlier

A new marker that could be used to diagnose fatal breast cancer up to one year ahead of current methods has been identified in a study led by UCL. The study found that changes detected in a part of DNA which the researches named EFC#93 could suggest early signs of deadly breast cancer. Importantly, these abnormal patterns are present in blood serum before the cancer becomes detectable in the…

Biomarker may predict early Alzheimer’s disease

Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have identified a peptide that could lead to the early detection of Alzheimer’s disease (AD). The discovery, published in Nature Communications, may also provide a means of homing drugs to diseased areas of the brain to treat AD, Parkinson’s disease, as well as glioblastoma, brain injuries and stroke. “Our goal was to…

Sixty-five new genetic risk markers for breast cancer discovered

Until now, familial breast cancer has only partly been linkable to genetic risk markers. In a worldwide joint effort, researchers have now identified further genetic variants that affect the risk for breast cancer. The study, which was conducted with participation of researchers from the German Cancer Research Center (DKFZ) and Heidelberg University Hospital, has now been published in Nature.…

Got eye freckles? The sun might be to blame

In a study well-timed for summer, vision scientists have found that eye freckles, dark spots on the colored part of the eye (iris), are more frequently found in people with higher lifetime exposure to sunlight. While not malignant, eye freckles could indicate the presence or risk of sunlight-triggered eye diseases like cataract or macular degeneration.

Plodding toward a pancreatic cancer screening test

Pancreatic cancer is one of the most deadly types of malignancies, with a 5-year survival rate after late diagnosis of only about 5%. The majority of patients—about 80%—receive their diagnosis too late for surgery. The disease spreads quickly and resists chemotherapy. In short, there is an urgent need for diagnostic tools to identify this cancer in its earliest stages.

Aiming for the earliest diagnosis of hepatocellular carcinoma

For almost three quarters of hepatocellular carcinoma (HCC) patients in Europe it is too late for curative treatment because the disease is often only diagnosed at a very advanced stage.

Potential predictor of glaucoma damage identified

Glaucoma, a leading cause of blindness worldwide, most often is diagnosed during a routine eye exam. Over time, elevated pressure inside the eye damages the optic nerve, leading to vision loss. Unfortunately, there’s no way to accurately predict which patients might lose vision most rapidly. Now, studying mice, rats and fluid removed from the eyes of patients with glaucoma, researchers at…

Biomarker Identified for Likely Aggressive, Early Stage Breast Cancer

The one-size-fits-all approach to early stage breast cancer creates a paradox: Millions of dollars are spent on unnecessary surgeries and radiation to treat women with low-risk ‘in situ’ lesions, an estimated 85% of which would never progress to invasive cancers. Meanwhile, the standard conservative treatment is insufficient for many early-stage tumors that have progressed past the in situ…
