Study Finds Unique Form of Chronic Sinusitis in Older Patients

Vanderbilt University Medical Center

Older patients with a diagnosis of chronic sinusitis — a disease of the nasal cavity and paranasal sinuses that often persists over many years — have a unique inflammatory signature that may render them less responsive to steroid treatment, according to a new study published by Vanderbilt researchers.

Air Pollution Increases ER Visits for Breathing Problems, but Rate Depends on Age, Pollutant and Lung Disease

American Thoracic Society (ATS)

As levels of ozone and fine particulate pollution (PM2.5) rise, more patients end up in the ER with breathing problems, according to the largest U.S. study of air pollution and respiratory emergency room visits of patients of all ages. The study was published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.

Fever alters immune cells so they can better reach infections

Cell Press

Fever is known to help power up our immune cells, and scientists in Shanghai have new evidence explaining how. They found in mice that fever alters surface proteins on immune cells like lymphocytes to make them better able to travel via blood vessels to reach the site of infection. Their work appears on January 15 in the journal Immunity.

JAMA report outlines recommendations for evaluation and management of penicillin allergy

Massachusetts General Hospital

While more than 32 million individuals in the U.S. have a documented penicillin allergy in their medical record, studies have shown that more 95 percent actually can be treated safely with this class of antibiotics, improving treatment outcomes and reducing the risk of infection with dangerous resistant pathogens such as Clostridium difficile (C. difficile). A review article in the January 15 issue of JAMA recommends best practices for evaluation of reported penicillin allergies and provides clinicians with guidance and tools to help determine appropriate procedures based on the severity of previously reported reactions.

Engineered T cells promote long-term organ transplant acceptance

University of Basel

Organ transplant rejection is a major problem in transplantation medicine. Suppressing the immune system to prevent organ rejection, however, opens the door to life-threatening infections. Researchers at the University of Basel's Biozentrum have now discovered a molecular approach preventing rejection of the transplanted graft while simultaneously maintaining the ability to fight against infections.

Could this widely used food additive cause celiac disease?

Frontiers

Myths about gluten are hard to bust. Intolerance, allergy, sensitivity, hypersensitivity. What is what? Celiac disease is none of these things. It is an autoimmune disorder, where gluten triggers the immune system to attack the gut. It is common, lifelong, and can seriously harm health - but nobody knows for sure what causes it. Now a review in Frontiers in Pediatrics says a common food additive could both cause and trigger these autoimmune attacks, and calls for warnings on food labels pending further tests.
