Eyes are the prize

Most patients are willing to donate eyes to research, but few do

2013-07-12
(Press-News.org) Far more people are willing to donate their eyes to research than actually are registered to donate, according to a study led by a Michigan State University student.

While demand for tissue remains high, the number of human eyes donated for research declined 28 percent between 1997 and 2004, said Andrew Williams, a third-year MSU College of Human Medicine student who led the study in the journal Current Eye Research.

"A lot of people aren't aware they can donate their eyes to research," Williams said. "They don't really know how to get the process started. It comes down to a lack of education."

Of roughly 200 patients with eye diseases surveyed in the study, 90 percent said they were willing to donate their eyes.

Among patients who were not registered to donate, 77 percent gave what the researchers called non-prohibitive reasons. For example, many patients said they weren't registered because they'd never been asked. Other patients believed their eyes were too diseased to donate, when in fact diseased eyes are particularly useful for research.

In some states, being an eye donor is separate from being an organ donor. Williams said he does not think many people notice a separate box may need to be checked specifically for eye donation. Among people who do donate their eyes, few designate them for research.

"The donation process is too complex," Williams said. "It could be structured better to facilitate donations."

Williams said states could simplify the donation process by providing people with more information and flagging patients who express interest in offering their eyes.

However, doctors are hesitant to ask afflicted patients to donate eyes.

"We were concerned about the doctor-patient relationship," Williams said, "but our thought was that it seems reasonable to have a pamphlet in the waiting room."

In the study, 41 percent of surveyed patients preferred learning about eye donation from their doctor, while 37 percent said they would prefer to learn from a pamphlet.

Patients also said they were more likely to consider donating if they had strong trust in their eye doctor.

Williams and his team have held meetings with Donate Life, a nonprofit organization responsible for increasing donations, to implement a simpler system for donating eyes.

"Eye donation has restored sight to thousands of patients," Williams said. "If we were able to streamline the process, researchers could work much more efficiently."

Brain region implicated in emotional disturbance in dementia patients

2013-07-12
A study by researchers at Neuroscience Research Australia (NeuRA) is the first to demonstrate that patients with frontotemporal dementia (FTD) lose the emotional content/colour of their memories. These findings explain why FTD patients may not vividly remember an emotionally charged event like a wedding or funeral. The research team discovered that a region of the brain, called the orbitofrontal cortex, plays a key role in linking emotion and memories. "This step forward in the mapping of the brain will improve how we diagnose different types of dementia," says the ...

Interspecies transplant works in first step for new diabetes therapy

2013-07-12
CHICAGO --- In the first step toward animal-to-human transplants of insulin-producing cells for people with type 1 diabetes, Northwestern Medicine® scientists have successfully transplanted islets, the cells that produce insulin, from one species to another. And the islets survived without immunosuppressive drugs. Northwestern scientists developed a new method that prevented rejection of the islets, a huge problem in transplants between species, called xenotransplantation. "This is the first time that an interspecies transplant of islet cells has been achieved for an ...

Sculpting flow

2013-07-12
Have you ever noticed the way water flows around boulders in a fast-moving river, creating areas of stillness and intense motion? What if those forces of fluid flow could be controlled at the smallest levels? In May 2013, researchers from UCLA, Iowa State and Princeton reported results in Nature Communications about a new way of sculpting tailor-made fluid flows by placing tiny pillars in microfluidic channels. By altering the speed of the fluid, and stacking many pillars, with different widths, placements and orientations, in the fluid's path, they showed that it is ...

Study finds potential markers for severity of childhood arthritis

2013-07-12
Children who suffer from arthritis could one day receive more targeted treatment thanks to potential markers for the severity of the disorder discovered by researchers at the University of Adelaide and Women's and Children's Hospital. The early results of a world-first study looking at 115 children with juvenile arthritis have shown that changes in the levels of particular molecules known as prostanoids - which are formed from essential fatty acids - in the blood of these patients may predict the course of arthritis more accurately, and help provide more individualized ...

Alarmingly high substance abuse rates found among street children in low-income countries

2013-07-12
INDIANAPOLIS -- Millions of children worldwide live on the streets. A review and analysis of 50 studies on substance abuse by street children in 22 resource-constrained countries has found lifetime substance use to be both common and high, posing serious threats to their health as well as for their chances for reintegration into society. "The most important conclusion to draw from this large number of studies is not only is substance abuse by street children highly prevalent in low-income countries; it is largely ignored," said Paula Braitstein, Ph.D., associate research ...

Health-care system factors may have less influence on kidney-related racial disparities

2013-07-12
Among kidney disease patients receiving pre-dialysis care in a universal healthcare system, black patients experienced a faster progression to kidney failure than whites. The faster decline in kidney function among black compared with white patients was predominantly present in patients with diabetes and in patients with more advanced kidney dysfunction. Findings may help explain why blacks are more prone to develop kidney failure than whites. Washington, DC (July 11, 2013) — Among patients with kidney disease who received specialized pre-dialysis care in a universal ...

Novel drug acts in unique way to protect against kidney injury

2013-07-12
A novel drug called Bendavia can help prevent acute kidney injury in animal models and is currently being studied in clinical trials for kidney disease. Bendavia acts by protecting a unique compound called cardiolipin, which is only found in mitochondria and is essential for keeping cells alive and functioning. Acute kidney injury has more than doubled since 2000, causing nearly 39,000 deaths in 2009. Washington, DC (July 11, 2013) — New research reveals the mechanism by which an experimental drug can protect the kidneys from sudden damage, called acute kidney injury ...

The brain processes complex stimuli more cumulatively than we thought

2013-07-12
A new study reveals that the representation of complex features in the brain may begin earlier—and play out in a more cumulative manner—than previously thought. The finding represents a new view of how the brain creates internal representations of the visual world. "We are excited to see if this novel view will dominate the wider consensus" said senior author Dr. Miyashita, who is also Professor of Physiology at the University of Tokyo's School of Medicine, "and also about the potential impact of our new computational principle on a wide range of views on human cognitive ...

Geothermal power facility induces earthquakes, study finds

2013-07-12
An analysis of earthquakes in the area around the Salton Sea Geothermal Field in southern California has found a strong correlation between seismic activity and operations for production of geothermal power, which involve pumping water into and out of an underground reservoir. "We show that the earthquake rate in the Salton Sea tracks a combination of the volume of fluid removed from the ground for power generation and the volume of wastewater injected," said Emily Brodsky, a geophysicist at the University of California, Santa Cruz, and lead author of the study, published ...
