Study: Lowering blood pressure helps prevent mental decline

Lowering blood pressure more than usually recommended not only helps prevent heart problems, it also cuts the risk of mental decline that often leads to Alzheimer’s disease, a major study finds. It’s the first time a single step has been clearly shown to help prevent a dreaded condition that has had people trying crossword puzzles,

High Blood Pressure Threatens Aging Brain, Study Says

WEDNESDAY, July 11, 2018 — Here’s yet another reason to get your blood pressure under control: High blood pressure later in life may contribute to blood vessel blockages and tangles linked to Alzheimer’s disease, new research suggests. Tracking nearly 1,300 older people until they died, scientists found markedly higher risks of one or more brain

Chloride blood test: Procedure, purpose, and level results

Most people will not be aware that they have hyperchloremia because the symptoms are almost impossible to identify. Doctors often discover the condition from a chloride blood test, which is part of a routine blood screening to monitor or diagnose electrolyte levels. A doctor might do these tests if they suspect a person has any

‘Bad’ antibodies let blood infections rage

Certain antibodies in a patient’s blood stream may enable life-threatening bacterial infections to spread instead of fighting them off, a University of Queensland study has found. UQ Diamantina Institute Senior Research Fellow Dr. Timothy Wells said the discovery may be helpful for treating or preventing sepsis in some patients in the future. Researchers examined how

With gene editing, researchers cure blood disorder in fetal mice

With the combined efforts of three Yale laboratories, researchers conducted the first demonstration of site-specific gene editing in a fetus, correcting a mutation that causes a severe form of anemia. The technique, described in a paper published June 26 in Nature Communications, involves an intravenous injection of nanoparticles carrying a combination of donor DNA and

Are YOU at risk of developing a shock blood clot from flying?

Are YOU at risk of developing a shock blood clot from flying? Travel-related thrombosis can strike healthy adults months after a flight – so here are the warning signs to watch out for Deep vein thrombosis can strike otherwise healthy adults 8 weeks after flying Travel-related deep vein thrombosis (DVT) has remained a hot topic

Modern blood cancer treatments require new approach for monitoring, reporting side effects

Treatment changes including the advent of targeted and immune therapies have dramatically improved survival for blood cancers, but new report calls for improved evaluation of poorly understood side effects that may develop over time.—- Survival rates for blood cancers—including lymphoma, myeloma and some types of leukaemia—have dramatically increased over the past decade, due in great

Children with kidney disease show blood flow changes in brain

Blood flow changes in the brains of children, adolescents and young adults with chronic kidney disease may explain why many face a higher risk of cognitive impairment, according to a study published online in the journal Radiology. Prior research has linked chronic kidney disease, a condition characterized by the loss of kidney function over time,

Algorithm predicts dangerous low blood pressure during surgery

Scientists have developed an algorithm that predicts potentially dangerous low blood pressure, or hypotension, that can occur during surgery. The algorithm identifies hypotension 15 minutes before it occurs in 84 percent of cases, the researchers report in a new study published in the Online First edition of Anesthesiology, the peer-reviewed medical journal of the American

Blood mutations could contaminate genetic analyses of tumors

Genetic mutations in blood cells that have made their way into tumors could be red herrings that mislead physicians looking for genetic changes in tumors that are helping to drive the cancer. This finding is significant because physicians could make misinformed treatment decisions. At the 2018 American Society of Clinical Oncology Annual Meeting this week,

Researchers transform human blood cells into functional neurons

Human immune cells in blood can be converted directly into functional neurons in the laboratory in about three weeks with the addition of just four proteins, researchers at the Stanford University School of Medicine have found. The dramatic transformation does not require the cells to first enter a state called pluripotency but instead occurs through

Blood test shows potential for early detection of lung cancer

A test that analyzes free-floating DNA in the blood may be able to detect early-stage lung cancer, a preliminary report from the ongoing Circulating Cell-Free Genome Atlas (CCGA) study suggests. The findings, from one of the first studies to explore whether sequencing blood-borne DNA is a feasible approach to the early cancer detection, will be

Some blood stem cells are better than others

In your body, blood stem cells produce approximately 10 billion new white blood cells, which are also known as immune cells, each and every day. Even more remarkably, if some of these blood stem cells fail to do their part, then other blood stem cells pick up their slack and overproduce whichever specific type of

New era for blood transfusions through genome sequencing

Most people are familiar with A, B, AB and O blood types, but there are hundreds of additional blood group “antigens” on red blood cells—substances that can trigger the body’s immune response—that differ from person to person. Each year, up to 16 deaths reported to the Federal Drug Administration are attributed to mismatches in red

IgG antibodies activate blood platelets and contribute to the severity of anaphylaxis

The most severe allergic reaction, anaphylaxis (or anaphylactic shock), is the result of an inappropriate immune reaction following the introduction of a usually harmless antigen into the body. The production of antibodies against this antigen (or allergen) allows the formation of antibody-antigen complexes that trigger a massive secretion of potent mediators, resulting in organ failure,
