Antibiotic therapy improves moderate exacerbations of mild-to-moderate COPD

A multicenter trial found that antibiotic treatment with amoxicillin/clavulanate significantly improved clinical cure rates and prolonged the median time to next exacerbation in patients with mild-to-moderate COPD. Patients with elevated capillary C-reactive protein (CRP) levels were more likely to be cured without antibiotics.

Blood sugar control does not help infants and children undergoing heart surgery

A recent study funded by the NIH found that tight glycemic control in pediatric cardiac surgery patients did not reduce healthcare-related infections, organ failure, or death. The study's findings diverge from previous studies on adult intensive care unit (ICU) patients who showed benefits from blood sugar control.

Strategy developed to improve delivery of medicines to the brain

Scientists at NIEHS discover a way to turn off P-glycoprotein, a major gatekeeper preventing medicinal drugs from reaching the brain, allowing small therapeutic agents to cross the blood-brain barrier. This breakthrough could lead to new treatments for central nervous system diseases such as brain and spinal cord injury, brain cancer, ...

Tight glycemic control has no proven benefits for children in the cardiac ICU

A new study conducted at Boston Children's Hospital found that tight blood sugar control does not benefit pediatric patients undergoing heart surgery. The Safe Pediatric Euglycemia in Cardiac Surgery (SPECS) trial examined the effects of insulin on glucose management and showed no impact on infection rates, length of stay, or mortality.
