Red blood cells exposed to oxygen deficiency protect against myocardial infarction
Red blood cells exposed to oxygen deficiency protect against myocardial infarction, according to a new KI study published in the Journal of Clinical Investigation. The study also shows that the protective effect is enhanced by a nitrate-rich vegetable diet. Red blood cells carry oxygen from the lungs to all of the body’s cells and carbon […]
Hyperbaric Oxygen Therapy Promising for Crohn’s Fistulas
DENVER — Hyperbaric oxygen therapy (HBOT) can help heal bowel fistulas in patients with advanced Crohn’s disease, according to a systematic review and meta-analysis. Overall, use of HBOT was associated with a 87% clinical response rate for all fistula subtypes, with more than half of the patients achieving clinical remission, or closure of the fistula […]
Oxygen Concentration During Surgery: No Help for Post-Op Nausea, Vomiting
NEW ORLEANS — There was no benefit to giving patients supplemental oxygen during surgery to reduce postoperative nausea and vomiting (PONV), according to a post hoc analysis of a randomized trial. The multiple cross-over cluster trial had eight isolated operating rooms randomized to alternate between 80% versus 30% fractions of inspired oxygen every 2 weeks […]
After Cardiac Arrest, No ‘Best’ Blood Pressure, Oxygen Target
BARCELONA — Shifting blood pressure and oxygen targets failed to budge outcomes for comatose survivors of out-of-hospital cardiac arrest, the BOX trial showed. A higher mean arterial blood-pressure target of 77 mm Hg — hypothesized to potentially maintain better cerebral perfusion — had no impact on the proportion of patients who died or left the […]
Sulfur enhances carbon storage in the Black Sea: Study finds new explanation for the accumulation of organic compounds in oxygen-depleted marine areas
The Black Sea is an unusual body of water: below a depth of 150 metres the dissolved oxygen concentration sinks to around zero, meaning that higher life forms such as plants and animals cannot exist in these areas. At the same time, this semi-enclosed sea stores comparatively large amounts of organic carbon. A team of […]
