Is there a DNA exam pack underneath a tree?

Welcome to Second Opinion, a weekly roundup of heterogeneous and under-the-radar health and medical scholarship news. Sign adult here to have this newsletter delivered to your inbox each Saturday morning.

If we uncover a present subsequent week and it turns out to be a genetic DNA test kit, what have we unequivocally opened?  How many can that exam tell we about your destiny health or who your relatives unequivocally are?

Not as many as we competence think, according to Timothy Caulfield, Canada Research Chair in health law and routine during a University of Alberta.

Caulfield has taken dual direct-to-consumer genetic tests — 23andme and AncestryDNA. He schooled he’s Irish and that his earwax is wet, not dry. There was no information about that chronicle is preferable.

Caulfield was also told that if he cooking asparagus he will expected be means to smell a metabolite in his urine — something he presumably didn’t need a genetic exam to reveal.

He also schooled he has a aloft risk of heart illness and colorectal cancer. But even that doesn’t tell him much, given his risk of both diseases is still really low.

What should he do with this information?

The personalized recommendation he perceived is what he already knows — eat a healthy diet, live a healthy lifestyle — recommendation many people won’t take no matter what their DNA exam formula reveal.

“The whole suspicion is that this information is empowering,” Caulfield said. “But research has shown that people don’t change their poise formed on this kind of information.”

What about a risk of divulgence dim family secrets, such as training your genuine father is not who we thought? Caulfield pronounced it would take some additional genetic sleuthing.

“It would have to be a bit of batch information that doesn’t make clarity formed on a family story. It competence be a start of an worried conversation, though it’s not going to be definitive.”

Other things to cruise as we separate into a vial and send your genes by a mail: what is a association formulation to do with a data? Some companies are pure about their goal to share anonymized patron DNA information with researchers and curative companies.

“I cruise people should be cautious, and they should demeanour during a remoteness rules, review what you’re removing into,” Caulfield said.

In May, Parliament upheld a Genetic Non-Discrimination Act protecting Canadians from carrying to divulge formula of genetic tests to word companies or to anyone else who tries to make genetic contrariety a condition of a contract.

“In other words, people are in no approach thankful to divulge their genetic exam formula to any business or classification (including curative companies, investigate groups, employers, insurers), nor should they feel any vigour to do so,” a orator for Canada’s Privacy Commissioner told CBC News in an email.

“If an sold does wish for formula to be disclosed (for example, for investigate purposes), agree contingency be in writing, entirely sensitive and openly given.”

The consumer DNA exam kits are being advertised as holiday gifts and there are many variations, including contrariety for booze welfare and even exam kits for pets.

“So have fun with it maybe, though don’t put too many batch in a results,” Caulfield said.

The genetic information won’t indispensably yield assent of mind by identifying what diseases we can stop worrying about. Knowing what diseases run in a family is a improved barometer of destiny health risks, he said.

The Canadian College of Medical Geneticists has advised opposite creation medical decisions formed on direct-to-consumer genetic exam results.

It’s also a present that competence keep on giving either we wish it or not. Caulfield keeps removing updates from one association as a genetic investigate becomes some-more refined. And a updated analyses exhibit that his Irishness is slipping.  

“I used to be 100 per cent Irish. Now I’m 88.9 and we have a small bit of Welsh. I’m removing reduction Irish.”

MRI color warnings

There were new warnings this week about a color used in MRI scans that could leave steel deposits in a brain.

The U.S. Food and Drug Administration issued a reserve proclamation about some gadolinium-based contrariety agents injected intravenously during an MRI indicate to urge a prominence of viscera and tissues. Gadolinium is a complicated metal, and there is justification that snippet amounts can be defended in a body.

The U.K. inhabitant health management has suspended a use of dual products, and a European Medicines Agency has singular a use of some of a dyes.

The health agencies highlight that so distant there is no justification that a gadolinium deposits have caused any inauspicious neurological effects.

But a U.K. group said, “Data on long-term effects of gadolinium deposition in brain, or other tissues, are really limited.”

Last Jan Health Canada announced it was operative with manufacturers to refurbish a labelling on gadolinium contrariety agents to embody information about a justification of gadolinium mind deposits after steady use. Health Canada recommends regulating a lowest probable dose.

“To date, Health Canada has perceived no Canadian box reports suggesting gadolinium deposits in a mind compared with use of gadolinium contrariety agents, nor any reports of disastrous health effects occurring in Canada due to gadolinium accumulation in a brain,” pronounced a orator for Health Canada in an email to CBC News, adding that Health Canada is monitoring a situation.

Dogs face special holiday health risk

There’s no need for a DNA exam to know that chocolate is dangerous for dogs — though that risk is top during Christmas.

A investigate in a BMJ’s special Vet Edition warns of a “significant peak” in a risk of chocolate poisoning in dogs over a holidays.

Chocolate contains a chemical called theobromine, a opiate identical to caffeine. Humans can hoop it, though it’s nasty things for a four-legged friends. It can means vomiting, diarrhea, increasing heart rate and even seizures.

“Humans routine it really quickly, so we can eat chocolate with happy abandon,” P-J Noble, a veterinarian during a Small Animal Teaching Hospital in Liverpool, U.K., and one of a authors of a study, told CBC’s Kas Roussy.

“In dogs, they don’t get absolved of it really quickly.  It hangs around and builds adult to poisonous levels really easily.”

Researchers have famous for some time that chocolate and dogs don’t mix. But Noble and his group wanted to find out either dog bearing to chocolate was tied to any of a vast holidays — Christmas, Easter, Valentine’s Day or Halloween.

After reviewing millions of electronic health annals from 500 oldster clinics in a U.K., they found Christmas kick them all when it came to chocolate exposure.  

Santa Claus figurines, Advent calendars, and Christmas tree decorations done of chocolate were high on a doggy list of favourites.

But who can censure Fido for adhering his muzzle where it doesn’t belong? Dogs like sugar, and when it’s on arrangement it’s tough to resist.

One sold bushy crony expected done Santa’s disobedient list. The investigate reports that a dog had ingested 6 Toblerones and 6 Terry’s Chocolate Oranges.

“I would feel ill after that,” says Noble.

None of a some-more than 300 cases of chocolate poisoning reported in this investigate was deliberate life-threatening, though too many of a good thing can be bad. When ingested in vast amounts, chocolate can be deadly for dogs, generally if it’s of a darker variety, Noble said.

So, Merry Christmas to all, contend Noble and his colleagues, “but keep a chocolate divided from your dog. Because no one wants to be going to a oldster on Christmas Day.”
