Teleophthalmology for screening, recurrence of age-related macular degeneration

Fri, 05/12/2014 - 2:40pm
No relevant delay between referral and treatment was found when teleophthalmology was used to screen for suspected age-related macular degeneration and, while teleophthalmology monitoring for recurrence of AMD did result in an average longer wait time for treatment reinitiation, it did not result in worse visual outcomes, according to a study.

Images of brain after mild stroke predict future risk

Fri, 05/12/2014 - 2:40pm
A CT scan of the brain within 24 hours of a mild, non-disabling stroke can predict when patients will be at the highest risk of another stroke or when symptoms may worsen, according to new research. Like stroke, a transient ischemic attack (TIA) is caused by restricted blood supply to the brain. Symptoms may last only a few minutes.

3-D printed heart could reduce heart surgeries in children

Fri, 05/12/2014 - 2:40pm
Being able to practice on a model heart allows doctors to optimize the interventional procedure pre-operatively. 3-D models can also be used to discuss the intervention with the medical team, patients and, in the case of congenital heart defects, with parents. It helps everyone affected to better understand what the procedure will involve.

Older cancer patients missing out on surgery

Fri, 05/12/2014 - 2:38pm
Older people are less likely to have cancer surgery compared to younger people, according to new data. A report reveals the difference in rates of surgery across 21 different cancer types. While many factors might be at play -- frailty, suffering more than one illness, being diagnosed at a late stage, patients choosing not to undergo surgery -- these statistics paint a worrying picture.

Dopamine helps with math rules as well as mood

Fri, 05/12/2014 - 2:38pm
Rule-applying neurons work better under the influence of the happy hormone, researchers have found. The chemical messenger dopamine – otherwise known as the happiness hormone – is important not only for motivation and motor skills. It seems it can also help neurons with difficult cognitive tasks, they report.

How stroke survivors could benefit from computer games

Fri, 05/12/2014 - 2:38pm
Stroke survivors can have “significant” improvement in arm movements after using the Nintendo Wii as physiotherapy, according to researchers. The popular computer remote could be customized to offer bespoke physiotherapy for stroke survivors in their own home, they say.

Type 2 diabetes risk starts in pregnancy

Fri, 05/12/2014 - 2:37pm
The risk of developing type 2 diabetes, obesity, and cardiovascular disease is affected by exposures in the uterus, research shows. Experts are now calling for updated guidelines in light of research evidence from the past decades.  The fetal programming hypothesis hinges around the idea that the intrauterine environment, the milieu in which the fetus is exposed as it grows, impacts the trajectory for disease risk later in life.

Light propagation in solar cells made visible

Fri, 05/12/2014 - 2:37pm
How can light which has been captured in a solar cell be examined in experiments? Scientists have succeeded in looking directly at light propagation within a solar cell by using a trick. The photovoltaics researchers are working on periodic nanostructures that efficiently capture a portion of sunlight which is normally only poorly absorbed.

Antioxidant capacity of orange juice is multiplied tenfold

Fri, 05/12/2014 - 2:37pm
The antioxidant activity of citrus juices and other foods is undervalued, experts say. A new technique for measuring this property generates values that are ten times higher than those indicated by current analysis methods. The results suggest that tables on the antioxidant capacities of food products that dieticians and health authorities use must be revised. Orange juice and juices from other citrus fruits are considered healthy due to their high content of antioxidants, which help to reduce harmful free radicals in our body, but a new investigation shows that their benefits are greater than previously thought.

Low levels of circulating protein linked with heart problems in mice with kidney disease

Fri, 05/12/2014 - 1:31pm
Decreased blood levels of a protein called Klotho increases the risk of heart disease in mice with chronic kidney disease, researchers report. If confirmed in humans, increasing Klotho levels may help protect the hearts of patients with chronic kidney disease.
