Biofluids – including blood, plasma, saliva, urine and even cheek swabs – can tell us a lot about a person’s health, which is why patients are routinely asked to provide these samples in the lab for testing. With a small amount of blood, for example, complex testing and screening of its chemistry, enzymes, lipoproteins and clotting can be performed. Because of their potency as a health barometer, whole blood and plasma are among the human biospecimens our clients demand most.

Researchers in Shanghai reviewed 21 studies that looked at more than 1,500 people and found that more than half of those studies “showed that regulating intestinal flora can effectively improve anxiety symptoms.”

A protein that has commonly helped doctors diagnose a heart attack could also be used to help predict heart problems years in advance. New research from Baylor University indicates that adding troponin I to a commonly used risk prediction model led to more accurate risk prediction for heart attack, stroke and heart failure hospitalization.

One of the hardest things about chronic fatigue syndrome is the stigma—the notion that it just might be all in your head. Chronic fatigue syndrome afflicts an estimated 800,000 to 2 million Americans and has no known cure. Symptoms include malaise, sleep problems, pain, dizziness and difficulty concentrating. The diagnosis, when made at all, is typically withheld until other diseases are ruled out.

Finding the right clinical trials for very sick patients may be getting more precise and timely.Rather than enrolling patients in a trial based on their cancer type or a biopsy conducted months or years earlier, researchers in the UK recently used blood tests to get an up-to-date profile of genetic faults in the blood of 100 patients. In 11 cases, the researchers used the data to enroll them into an available “molecularly matched” clinical trial.

Researchers analyze a lot of data about specific diseases to discover new biomarkers and better predict treatment outcomes.University of Nottingham UK researchers, however, have taken a wide-angle approach to data and disease, enabling computers to essentially teach themselves to better predict early death from chronic disease in a large middle-aged population.

Although the AIDS epidemic has ebbed, HIV infection remains prevalent, with about 5,000 new infections per day and nearly 37 million living with the virus. Thus, news this week that a second and third HIV infected patient appear to have recently been “cured” of the infection has kindled hope in the medical and patient communities.

Like household clutter hiding a homeowner’s keys, a malfunctioning cleaning system in brain cells is being linked to Alzheimer’s disease, according to new research. Improving the cellular cleaning system in lab animals makes Alzheimer’s symptoms nearly disappear, researchers say. Researchers have discovered that humans and animals with Alzheimer’s show signs of compromised mitophagy, the process […]

They’re foreign to us, yet part of us. Do the trillions of microbes in and on our bodies control us? Well, these bacteria, fungi, protozoa and viruses – collectively called the microbiome – are quite likely affecting our brains and behavior to some degree.
