UV exposure: why do we ignore the health risks?

Date: Jul-17-2014
Exposure to ultraviolet radiation is the leading cause of skin cancer. But although many of us know this, we still ignore safety recommendations. We investigate why.

After a concussion, persistent symptoms 'may be PTSD'

Date: Jul-17-2014
Long-term symptoms following a concussion are currently classed as post-concussion syndrome in the DSM-IV, but a new study suggests they may be indicative of PTSD.

Could being overweight benefit our health?

There are numerous health problems associated with being overweight. But two new studies suggest that overweight and obesity may be beneficial, particularly for the heart.

Asthma medication linked to growth suppression in children

By decoding the Asian liver fluke Opisthorchis viverrini, scientists raise hope of fighting a parasite that infects millions with liver and gall bladder diseases including cancers.

Study finds a 20-year decline in stroke risk and death rates

Date: Jul-16-2014
After 2 decades of better control of risk factors, researchers find that stroke rates for Americans have declined. And those who do have a stroke have a better chance of surviving.

Researchers have successfully restored memory and learning deficits in Alzheimer's mouse models by transplanting healthy brain cells into the hippocampus.

Liver transplant patients want to be involved in decision making

Date: Jul-16-2014







In the first study to reveal what liver transplant candidates think about

being involved in the decision to accept or reject a donor organ, researchers suggest more than

half wish to be informed of donor risk when a donor liver is offered. They also say nearly 80% of

these patients wish to be involved in the decision of whether to accept the organ or not.

Robert Porte, professor of surgery at University Medical Center Groningen in the Netherlands,

and colleagues write about their study of Dutch liver transplant candidates and recipient

patients in the journal Liver Transplantation.

The study revealed that almost 80% of liver transplant patients wish to be involved in the decision of whether to accept a donor organ or not.

There is a shortage of donor livers, which means across the world there are many patients

waiting to receive a transplant.

In the US, for example, the Organ Procurement and Transplantation Network (OPTN) estimates

there are currently over 16,000 patients waiting for a new liver.

In a bid to increase availability of organs, some countries like the US have relaxed the rules

for accepting donor organs a little. This means older donors or donors whose health status would

previously have made them ineligible are now included under the "extended criteria."

The authors say this results in a slightly greater possibility of higher donor-related

risks, such as disease transmission and graft failure.

Also, they note that medical evidence suggests discussions with transplant candidates about

donor-related risks vary from country to country, but commonly, recipient patients play an

inactive role in the decision making.

For the study, the team recruited 40 patients who were on the waiting list to receive a liver

transplant and 179 who had undergone the procedure at the University Medical Center between 2000

and 2010.

The participants were primarily middle-aged, Dutch men. All patients filled in the survey

questionnaires anonymously.

Most patients wish to be informed of risks at time offer is made

When they analyzed the responses, the team found up to three-quarters of patients wished to be

informed about donor-related risks and more than half wanted this to be done at the time the

organ offer is made.

Also, of the patients wishing to be informed, 79.8% said they wished to be involved in the

decision of whether to accept or reject the offered donor liver, 10.6% said they wished to

make the decision entirely themselves, and 9.6% expressed a wish not to be involved in decision

making at all.

Prof. Porte says the findings "clearly show that the majority of transplant candidates would

like to be involved in the decision-making process," and that:

"Implementing this knowledge and standardizing the content, the manner of transfer and the amount

of information we provide to our patients at the different time points along the transplant

allocation process will be important to provide the same opportunities and care to every patient

on the waiting list."

Meanwhile, in a study recently reported by Medical News Today, researchers

investigating ways to improve

transplant outcomes concluded, among other things, that the perceived risk of organ donors

transmitting cancer to their recipients is likely to have been overestimated.
