When oxygen levels drop, red blood cells switch into a new metabolic mode and absorb large amounts of glucose from the blood. This helps the body cope with thin air while also reducing blood sugar levels. A drug that recreates this effect reversed diabetes in mice, hinting at a powerful new treatment strategy.

New research suggests ultramarathons can alter red blood cells in ways that make them less flexible and more prone to breakdown, potentially interfering with how they deliver oxygen throughout the body. Scientists found signs of both mechanical stress from intense blood flow and molecular damage linked to inflammation and oxidative stress.

This gentler form of gene editing could offer a safer way to treat Sickle Cell disease by reactivating a fetal blood gene. Researchers say it opens the door to powerful therapies with fewer unintended side effects.

These episodes, referred to as a vaso-occlusive episodes, happen when sickled cells obstruct blood vessels. The degree of pain may range from a mild discomfort to a severe disabling pain where the person needs treatment in hospital. A new study has found that hospital-admitted patients who received the fluid Lactated Ringer's, a solution used to replace water and electrolyte loss in patients with low blood volume or low blood pressure, rather than normal saline, had shorter hospital lengths of stay, fewer readmissions to the hospital, and fewer days of intravenous opioid medications for pain control.

The team discovered that acceleration during shearing is a major factor in red blood cell destruction, beyond exposure time and shear stress. They recommend adding a flow buffer structure to the structural design of ventricular assist devices to reduce part of the hemolysis caused by shear acceleration.

If both control proteins are switched off in mice, the animals develop severe anemia, as expected. Surprisingly, at the same time a cell type of the innate immune defense, the neutrophils, also dramatically decreases. Iron deficiency, a known defense mechanism against infectious pathogens, is a double edged sword, as it simultaneously curbs the defensive power of an important arm of the innate immune system.

High blood sugar and inflammation may also contribute to higher cardiovascular risk associated with red meat consumption, however, blood pressure and cholesterol were not associated with the higher CVD risk associated with red meat consumption. General consumption of fish, poultry and eggs was not associated with increased cardiovascular risk.

Other health and lifestyle factors in the checklist, which were part of the previous, 7-item scoring tool, are nicotine exposure, physical activity, diet, weight, blood glucose, cholesterol and blood pressure. The new sleep metric suggests 7-9 hours of sleep daily for optimal cardiovascular health for adults, and more for children depending on age.
