Scientists discover mosquitoes' unique blood-taste detectors
Scientists aren't sure how mosquitoes sense taste of blood, or how they know that this, of all things, is something to gorge on. Nothing else, not even sweet nectar, makes them pump as ferociously as when they're draining our veins. New research identifies a unique group of neurons that don't care about simple tastes like sweet or salty. Rather, they activate only when sugar, salt, and other components of blood are all present at once. (2020-10-12)

Symptoms of COVID-19 are a poor marker of infection, new UK population study shows
86% of UK residents who tested positive for COVID-19 during lockdown did not have the specific virus symptoms (cough, and/or fever, and/or loss of taste/smell), finds a new study by UCL researchers. The authors say a more widespread testing programme is needed to catch 'silent' transmission and reduce future outbreaks. (2020-10-07)

(2020-09-23)

Children who take steroids at increased risk for diabetes, high blood pressure, blood clots
Children who take oral steroids to treat asthma or autoimmune diseases have an increased risk of diabetes, high blood pressure, and blood clots, according to Rutgers researchers. The Rutgers study is the first to quantify these complications of oral steroids in a nationwide population of children. (2020-09-17)

The hormone glucagon may be a warning light for diabetes
Researchers from the University of Copenhagen are introducing a new biological concept in the fight against diabetes: glucagon resistance. Glucagon resistance or decreased sensitivity to the hormone glucagon increases the risk of type 2 diabetes. New research shows that glucagon resistance is particularly pronounced in people with fatty liver, and this may be the key to understanding the link between fatty liver and diabetes. (2020-09-17)

Metformin for type 2 diabetes patients or not? Researchers now have the answer
Metformin is the first-line drug that can lower blood sugar levels in type 2 diabetes patients. One third of patients do not respond to metformin treatment and 5 per cent experience serious side effects, which is the reason many choose to stop medicating. Researchers at Lund University in Sweden have now identified biomarkers that can show in advance how the patient will respond to metformin treatment via a simple blood test. (2020-09-17)

Not so similar: Depression, but not anxiety, linked with inflammation and metabolic change
Anxiety and depression are often linked and assumed to be closely related, but now research has shown for the first time that depression and anxiety have different biochemical associations with inflammation and lipid (fat) metabolism. This indicates that different, more targeted treatments may be possible to treat anxiety and depression. This work is presented at the ECNP Congress. (2020-09-14)

Researchers develop rapid test for ovarian cancer detection

The simple lateral flow test is based on rapid detection of abnormal sugar structures directly from the blood sample. (2020-09-11)

Shorter rest periods yield same results when measuring blood pressure
Current guidelines recommending five minutes of rest before a patient can receive a blood pressure screening may not be necessary for patients without high blood pressure. Average differences in blood pressure measurements obtained after zero or two minutes of rest were not significantly different (<+2 mm Hg) than readings obtained after five minutes of rest in people with systolic blood pressure <140 mm Hg. These findings illustrate the possibility for improvement in blood pressure screening efficiency, especially in busy health care settings. (2020-09-10)

The genetics of blood: A global perspective

Blood breakdown product commandeers important enzyme
The hemoglobin in the red blood cells ensures that our body cells receive sufficient oxygen. When the blood pigment is broken down, 'heme' is produced, which in turn can influence the protein cocktail in the blood. Researchers at the University of Bonn have now discovered in complex detective work that the 'activated protein C' (APC) can be commandeered by heme. At the same time, APC can also reduce the toxic effect of heme. (2020-09-04)

Virus in the blood can predict severe COVID-19
A blood test on hospital admission showing the presence or absence of SARS-CoV-2 can identify patients at a high risk of severe COVID-19. Admitted patients without virus in their blood have a good chance of rapid recovery. This according to researchers at Karolinska Institutet and Danderyd Hospital in a new study published in the scientific journal Clinical Infectious Diseases. (2020-09-02)

Physiological test for autism proves effective independent of co-occurring conditions
Developing a physiological test for diagnosing autism spectrum disorder (ASD), one that measures certain components in the blood, has the potential to be a paradigm shift for diagnosing ASD. However, the large heterogeneity of how ASD affects individuals has long been viewed as a key obstacle to the development of such a test. Research conducted at Rensselaer Polytechnic Institute, and published online today in the journal Research in Autism Spectrum Disorders, represents a significant step toward addressing this challenge. (2020-08-28)

Host tissue T cells may have an unexpected role in graft-versus-host disease
A new study has found that skin and intestinal T cells in the recipient survive conditioning regimens and continue to perform their normal functions. Under certain conditions, these T cells can become activated by donor white blood cells and play a previously unappreciated role in acute GVHD. (2020-08-28)

Spit in a tube to diagnose heart attack
A saliva test could fast track heart attack diagnosis, according to preliminary research presented today at ESC Congress 2020.1 The innovative technique requires patients to spit into a tube and provides results in 10 minutes, compared to at least one hour for the standard blood test. (2020-08-26)
