Blood pressure

How does the baroreceptor reflex work?

The baroreceptor reflex is a fascinating medical phenomenon. The reflex is controlled by specialized neurons that react in just a fraction of a second to keep blood pressure fairly consistent. For example, when you stand up, your blood pressure normally drops—rapidly. Yet you don't faint thanks to baroreceptors, which tell your heart rate to increase and push more blood to your brain. A new…

New techniques detects Lyme disease weeks before current tests

Researchers have developed techniques to detect Lyme disease bacteria weeks sooner than current tests, allowing patients to start treatment earlier. The new techniques can detect an active infection with the Lyme bacteria faster than the three weeks it takes for the current indirect antibody-based tests, which have been a standard since 1994. Another advantage of the new tests is that a positive…

Myelodysplastic syndrome

Genetic testing helps predict disease recurrence

A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.

Recommendations on venous blood sampling

Pre-analytics, in particular venous blood sampling has a major impact on the quality of laboratory diagnostic results. An estimated 75 percent of all "lab errors" are caused by errors during pre-analytics. Thus, the German Medical Association’s national guideline on laboratory diagnostics includes detailed guidance on pre-analytics, in particular venous blood sampling. In their…

AI approach to help myeloma patients

A multidisciplinary team of researchers from the National University of Singapore (NUS) has developed an artificial intelligence (AI) technology platform that could potentially change the way drug combinations are being designed, hence enabling doctors to determine the most effective drug combination for a patient quickly. Applying the platform towards drug resistant multiple myeloma, a type of…

Potential diagnostic test for Kawasaki disease

For the first time, researchers at University of California San Diego School of Medicine and Imperial College London, with international collaborators, have determined that Kawasaki disease (KD) can be accurately diagnosed on the basis of the pattern of host gene expression in whole blood. The finding could lead to a diagnostic blood test to distinguish KD from other infectious and inflammatory…

Patient blood management

Blood transfusions: Patient groups should be precisely defined

Although blood transfusion today is a well-established and safe procedure, the medical science community has not yet arrived at a consensus regarding appropriate patient blood management (PBM) methods. ‘Many PBM approaches have not yet been scientifically validated; consequently over- as well as under-transfusion might be associated with adverse events and complications for the patient,’…

Millions more: New guidelines could drastically raise hypertension numbers

Adopting new guidelines for high blood pressure (hypertension) would dramatically increase the number of people labeled as having the condition and being recommended for drug treatment, finds a study published by The BMJ today. The findings show that, if the guidelines were introduced in the US and China, more than half of those aged 45-75 years in both countries would be considered hypertensive.

Hematopoietic Stem Cells

What keeps our blood in balance

Blood is the juice of life, as while circulating through the body it delivers vital substances such as oxygen and nutrients to cells and tissues. Chemotherapy, radiotherapy and blood loss in general impoverish the system. A special kind of cells in the bone marrow, called hematopoietic stem cells (HSCs) is able to replenish the impoverished system by giving rise not only to red blood cells, but…

This green-blooded lizard could help fight malaria

Green blood is one of the most unusual characteristics in the animal kingdom, but it's the hallmark of a group of lizards in New Guinea. Prasinohaema are green-blooded skinks, or a type of lizard. The muscles, bones and tongues of these lizards appear bright, lime-green due to high levels of biliverdin, or a green bile pigment, which is toxic and causes jaundice. Surprisingly, these lizards…

New blood test predicts TB onset up to two years in advance

A new blood test has been found to more accurately predict the development of tuberculosis up to two years before its onset in people living with someone with active TB, according to research published online in the American Journal of Respiratory and Critical Care Medicine, an American Thoracic Society journal. Those living with someone with active TB are at highest risk for developing the…

ACE inhibitor side effects

Lowering blood pressure comes at a price

The recent ACC/AHA Guidelines have increased the number of patients said to have hypertension by up to 40 percent (new 130/80 mmHg). The international recommendation is to treat hypertension with angiotensin converting enzyme inhibitors (ACEIs). These drugs, however, have significant adverse effects: Often a chronic dry cough leads to patients withdrawing from treatment. On rare occasions, ACEIs…

MRI vs. Alzheimer's

Seeking leaks in the blood-brain barrier

‘With our new MRI method, we can finally visualise tiny leaks in the blood-brain barrier. They shed light on the vascular contribution to dementia and may indicate Alzheimer’s disease. However, the MRI scan is only a tool to diagnose cerebrovascular damage. We have not yet found a cure for Alzheimer’s,’ confirms Walter H Backes, medical physicist and professor at Maastricht University…

TCAR (Transcarotid artery revascularization)

Reversing blood flow reduces stroke risk during carotid artery procedure

Loyola Medicine is the first academic medical center in Illinois to use the TCAR system, which reduces stroke risk during carotid artery procedures by temporarily reversing blood flow. Carotid arteries on each side of the neck supply blood to the brain. In patients with carotid artery disease, a build-up of plaque can cause blockages. A common method to open the artery involves a balloon…

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…

How caffeine may help diagnose Parkinson’s disease

Testing the level of caffeine in the blood may provide a simple way to aid the diagnosis of Parkinson’s disease, according to a study published in the online issue of Neurology, the medical journal of the American Academy of Neurology. The study found that people with Parkinson’s disease had significantly lower levels of caffeine in their blood than people without the disease, even if they…
