More evidence linking common bladder medication to a vision-threatening eye condition

A drug widely prescribed for a bladder condition for decades, now appears to be toxic to the retina, the light sensing tissue at the back of the eye that allows us to see. After an initial report last year that Elmiron (pentosan polysulfate sodium) may be associated with retinal damage, three ophthalmologists conducted a review of patients at Kaiser Permanente in Northern California. They found that about one-quarter of patients with significant exposure to Elmiron showed definite signs of eye damage, and that this medication toxicity could masquerade as other known retinal conditions, such as age-related macular degeneration or pattern dystrophy. The research will be presented today at AAO 2019, the 123nd Annual Meeting of the American Academy of Ophthalmology.

Another reason to get cataract surgery: It can make you 48% safer on the road

The ability of cataract surgery to restore sight is well known. People say they're stunned by the vibrancy of color after surgery and the improvement in night vision. Some can even reduce their reliance on glasses. But can you quantify that improved quality of vision? To find out, researchers in Australia used a driving simulator to test patients' vision before and after cataract surgery. They found that near misses and crashes decreased by 48 percent after surgery. The researchers present their study today at AAO 2019, the 123rd Annual Meeting of the American Academy of Ophthalmology.

Antibody-based eye drops show promise for treating dry eye disease

Researchers at the University of Illinois at Chicago are the first to identify the presence of a specific type of antibody, called anti-citrullinated protein autoantibodies, or ACPAs, in human tear fluid. They are also the first to demonstrate that patients with dry eye disease experienced reduced signs and symptoms of the condition in response to a new eye drop treatment —- made from pooled human antibodies—that targets ACPAs.

NASA sees Atlantic subtropical storm Melissa form off New England coast

Satellite data has confirmed the formation of Subtropical Storm Melissa. NASA's Terra Satellite provided a visible image the former Nor'easter turned subtropical storm off the coast of New England.

Hydrologic simulation models that inform policy decisions are difficult to interpret

Hydrologic models that simulate and predict water flow are used to estimate how natural systems respond to different scenarios such as changes in climate, land use, and soil management. The output from these models can inform policy and regulatory decisions regarding water and land management practices.

Food-insecure Canadian households may have trouble affording prescription medication

Food insecurity is linked to higher disease rates but not much is known about the reasons for this. A new study of more than 10,000 Canadian households shows that this connection may be at least partially attributed to lack of access to prescription medication.

National focus on overdose prevention should include alcohol too, study suggests

For several years, the national spotlight has shone on the need to prevent and rapidly treat opioid overdoses. But a new study suggests a need for more focus on the risk of alcohol overdoses among people who use opioids of all kinds, as well as cocaine, marijuana and certain prescription drugs.

How preprocessing methods affect the conversion efficiency of biomass energy production

Research on energy production from biomass usually focuses on the amount of energy generated. But it is also important to consider how much energy goes into the process, a component that is often neglected, says Tony Grift, professor of Agricultural and Biological Engineering in the College of Agricultural, Consumer and Environmental Sciences and the Grainger College of Engineering at the University of Illinois.

Contextual engineering improves success of projects in non-industrial societies

Humanitarian engineering projects often focus on bringing western technologies to non-industrialized societies. But environmental and cultural factors in these locations may be very different from conditions in the West, and the projects may not meet client needs if engineers do not fully understand the context in which they are operating.
