New gel pill could mean an end to injections
Scientists in India have developed a new gel that is taken orally and is capable of delivering drugs to manage diseases often requiring an injection. The research, published in the journal Polymer International, suggests the gel could offer a painless way of treating diabetes, ulcerative colitis, Crohn’s disease, bowel cancer, constipation and some infections, all of which require local drug delivery.  more

Sleep apnea associated with stomach acid backflow into throat
Medical researchers have long suspected a relationship between gastro-esophageal reflux disease (GERD) and obstructive sleep apnea (OSA), two medical conditions which can have a deleterious effect on a patient’s quality of life. Now, a team of Canadian researchers has determined that there are significant relationships between laryngopharyngeal reflux (LPR), OSA, and upper airway sensory impairment.  more

Bacterial cause of Crohn’s disease?

Inhaled nitrite therapy may help babies suffering in a low-oxygen state
Scientists from the National Institutes of Health (NIH) Clinical Center and the Loma Linda University School of Medicine have found that use of an inhaled nitrite spray may help babies diagnosed with persistent pulmonary hypertension of the newborn (PPHN). Premature newborns and those with pneumonia or heart problems often develop PPHN. This often-fatal disease causes high blood pressure in an infant’s lungs and places the baby in a low-oxygen state.  more
