Experts create quality improvement blueprint to reduce repetitive lab tests for hospitalized patients

In a review article publishing this week in JAMA Internal Medicine, physicians at Johns Hopkins, along with experts from several other institutions across north America, compiled published evidence and crafted an experience-based quality improvement blueprint to reduce repetitive lab testing for hospitalized patients.

New x-ray analysis methodology reveals structure of disordered protein

Scientists at The University of Notre Dame have shown that disordered proteins have a structure very close to what would be expected for a truly random structure using a novel X-ray scattering (SAXS) analysis methodology.

Researchers develop novel blood analyzer to improve anemia detection

About one quarter of the world's population suffers from anemia, a disease caused by a concentration deficiency of hemoglobin in red blood cells. To reduce the burden of anemia, health officials need a better picture of the disease's global impact, an understanding made viable by a portable and affordable way to analyze blood.

Study suggests frequent blood donation as feasible and safe option for donors

Giving blood more frequently – up to every 8 weeks for men and every 12 weeks for women – has no major side effects and could help to increase blood stocks, according to the first ever randomised trial of blood donation involving more than 45000 people in England published in The Lancet.

Donors could give blood more frequently than current intervals, study shows

New research shows that blood donors could safely give blood more frequently than is allowed at present. At the moment in the UK men can give blood every 12 weeks, women every 16 weeks.

New device can monitor mitochondria in the heart to predict cardiac arrest

A new device can assess in real time whether the body's tissues are receiving enough oxygen and, placed on the heart, can predict cardiac arrest in critically ill heart patients, report researchers at Boston Children's Hospital and scientists from Cambridge device maker Pendar Technologies.

Immune cells may play crucial role in helping the brain heal after hemorrhage or stroke

While immune cells called neutrophils are known to act as infantry in the body's war on germs, a National Institutes of Health-funded study suggests they can act as medics as well. By studying rodents, researchers showed that instead of attacking germs, some neutrophils may help heal the brain after an intracerebral hemorrhage, a form of stroke caused by ruptured blood vessels.

Combination of anti-malarial drug and photosensitizer could effectively kill cancer cells

Artemisinin, a potent anti-malarial drug, has been widely hailed as a promising alternative cancer treatment. Scientists from the National University of Singapore recently showed that its anti-cancer properties could be enhanced by 10 folds when used in combination with Aminolaevulinic acid, a photosensitizer or a drug which, upon exposure to light, leads to generation of free radicals that can kill cells.

Study: New oral drug helps control glucose, reduces need for insulin in patients with type 1 diabetes

A University of Colorado Anschutz Medical Campus study finds sotagliflozin helps control glucose and reduces the need for insulin in patients with type 1 diabetes.

Novel compounds found to be highly effective in preventing transmission of malaria parasites

Significant headway has been made in controlling malaria. However, two vexing problems remain: currently available treatments are unable to block transmission of the parasite that causes the disease, and the parasite often becomes resistant to drugs.

Newly-discovered mutation highlights complex genetic network that underpins blood disorder

Porphyrias, a group of eight known blood disorders, affect the body's molecular machinery for making heme, which is a component of the oxygen-transporting protein, hemoglobin. When heme binds with iron, it gives blood its hallmark red color.

Incidence of cancer in stroke survivors found to be almost twice that of general population

Some stroke survivors may have underlying cancer, according to an observational study to be presented at the ESMO 2017 Congress in Madrid.

Researchers investigate link between thyroid hormone and red blood cell production

For more than a century, physicians have anecdotally noted that patients with an underactive thyroid - often caused by iodine deficiency - tended to also have anemia. But the link between thyroid hormone and red blood cell production has remained elusive.

Study investigates feasibility and accuracy of CCHD screening with new Masimo iSpO2

Masimo announced today the findings of a recently published study in which researchers in Maastricht, The Netherlands evaluated the performance of Masimo iSpO2 Rx in screening newborns for critical congenital heart disease (CCHD).

Research reveals LEGO-like stacking of protein complexes

When hemoglobin undergoes just one mutation, the protein complexes stick to one another, stacking like LEGO blocks to form long, stiff filaments.

Coffee consumption connected to a longer life

At the European Society of Cardiology, ESC Congress 1 last weekend, Spanish researchers working as part of the long term project Seguimiento Universidad de Navarra (SUN) Project, presented their new study that suggests coffee intake might be tied to a longer life. The study included around 20,000 Spanish participants.

Scientists develop new system to identify and characterize regulatory DNA sequences

Scientists from the Children's Medical Center Research Institute at UT Southwestern have developed an innovative system to identify and characterize the molecular components that control the activities of regulatory DNA sequences in the human genome.

Living near newly built roads in Ethiopia linked to higher rates of infant mortality

Researchers have shown that living near newly built roads in Ethiopia is associated with higher rates of infant mortality. Proximity to new roads has negative health effects because of toxic waste dumped illegally during the construction phase, according to early research by economists at Queen Mary University of London and Trinity College Dublin.
