Researchers call for next chapter in improving patient safety by reducing misdiagnosis

Posted: 14 Nov 2015 03:52 PM PST

Approximately 12 million people in the United States experience diagnostic errors annually, but it is time for a change, according to experts, who say that by reducing misdiagnosis, patient safety is measurably improved.

Injection instead of laser may be viable treatment option for diabetic retinopathy

Posted: 14 Nov 2015 03:50 PM PST

Among patients with proliferative diabetic retinopathy, treatment with an injection in the eye of the drug ranibizumab resulted in visual acuity that was not worse than panretinal photocoagulation at two years, according to a study.

One-step test for hepatitis C virus infection developed

Posted: 14 Nov 2015 03:50 PM PST

A cost-effective one-step test that screens, detects and confirms hepatitis C virus (HCV) infections has been developed by researchers. Current blood-based HCV testing requires two steps and can be expensive, inconvenient and is not widely available or affordable globally.

Parkinson drug may prevent, delay AMD

Posted: 13 Nov 2015 03:25 PM PST

A significant discovery has been made that might lead to the delay or prevention of the most common cause of blindness in the elderly: age-related macular degeneration (AMD). Patients who take the drug L-DOPA (for Parkinson Disease, Restless Legs or other movement disorders) are significantly less likely to develop AMD and, if they do, it is at a significantly later age.

3-D printing aids in understanding food enjoyment

Posted: 13 Nov 2015 03:13 PM PST

Tasting food relies on food volatiles moving from the back of the mouth to the nasal cavity, but researchers have wondered why airflow doesn't carry them in the other direction, into the lungs. Now a team of engineers, using a 3-D printed model of the human airway from nostril to trachea, has determined that the shape of the airway preferentially transfers volatiles to the nasal cavity and allows humans to enjoy the smell of good food.

Cyclin' out of gear: Malaria parasites grinding to a halt

Posted: 13 Nov 2015 03:13 PM PST

Scientists have uncovered the role of cyclin -- the protein molecule that drives the growth of malaria within mosquitoes. The research could pave the way to better understanding of how the malaria parasite thrives and lead to potential new treatments.

Today's disposable society: Pharmaceuticals and other contaminants of emerging concern

Posted: 12 Nov 2015 09:37 AM PST

An increasing amount of drugs taken by humans and animals make it into streams and waterways, and pharmaceutical pollution has had catastrophic ecosystem consequences despite low levels of concentration in the environment. The effect of pharmaceuticals and other contaminants of emerging concern on the environment has been the focus of recent research.

Feeding at-risk infants gluten increases risk of developing celiac disease

Posted: 12 Nov 2015 09:35 AM PST

Intake of gluten up until two years of age increases risk of celiac disease at least two-fold in children with genetic risk factors for this disease, according a new study.

Uneven growth of identical twins may begin in first few days after conception
