Grand Rounds 4.22: The Future of Medicine

It’s a great pleasure for me to host Grand Rounds again after almost a year. The idea of Nick Genes shines more than ever so I hope I can show you plenty of useful and valuable submissions from the medical blogosphere. So this time, the topic is the future of medicine which means I’ll feature some blogposts about genetics and web 2.0 as medicine might be centered around these two terms in the future. Enjoy it!

Editor’s Choice (Genetics or Web 2.0):

Karina S. Descartin at The story of healing talked about Jay Parkinson, the web-savvy doctor and use of media in medicine.

At Scienceroll, I had an interview with Jay Parkinson, or if you would like to know more about web 2.0 and medicine, check out my recently published slideshow.

Personalized Genetics: Coffee, Cancer and a Pharmacogenomic Therapy

Even if I should study emergency medicine now, I would like to share interesting and useful links with you. Here are the most important articles, announcements of personalized genetics from the last few days. This edition focuses on breast cancer:

  • Pharmacogenomics Rising (The Gene Sherpa): LabCorp will study the role of polymoprhisms in cytochrome p450 2D6 and women’s response to breast cancer.

A cardinal rule in clinical cancer genetics is that you always want to do the genetic test on someone in the family who has had a cancer diagnosis that is suspicious for the risk syndrome that you are considering. If either of this woman’s aunts were alive, they would clearly be the best people to test first.

However, they both died of their disease. In the absence of other individuals with cancer to test, the patient’s healthy father would be the next best person to test.

dna-ladder50.jpg

Almost a decade later, this vision of personalised medicine has yet to become reality. People with hard-to-treat diseases like depression are still being prescribed drugs by trial and error. Adverse drug reactions are still one of the leading causes of death in the developed world.

Ruckus Nation: a challenge for children

hopelab.JPGI’m so amazed by Hopelab‘s projects as they always try to find creative ways to raise awareness on health and to promote prevention. Hopelab is a non-profit organization dedicated to improving the health and quality of life of young people with chronic illness. You may remember my post on their previous project: Fighting cancer with video games.

Now, Piers Sutton, the communications coordinator at HopeLab, has an important announcement for you:

HopeLab is launching an initiative to address childhood obesity that we believe may be of interest to you and your members.

This fall, HopeLab is sponsoring an online competition called “Ruckus Nation” which challenges participants to imagine innovative products that will increase physical activity among kids ages 11 to 14. The competition is open to people of all ages; but students are especially encouraged to join in, as individuals or in teams.

10 Tips for How to Acquire a Disease

I’m an admirer of Wade Meredith’s writings at Healthbolt.net and after reading his post on How to Give Yourself Diabetes, I realized that sarcasm makes it easier to reach people with important messages.

Now, I’d like to provide a list of tips not just how to get sick, but how to get even a serious disease.

1. Forget about sport! 30 minutes of walking takes too much time, and we can’t do exercises 5-6 times a week. Physically inactive people are more likely to die early, to experience major illnesses such as heart disease, diabetes and to get banal infections. So enjoy your favourite armchair and watch the TV!

healthy-heart.gif

2. Get fat! If your body mass index (kg/m2) is at least equal to or more than 25, then you’re on the right way towards cardiovascular diseases, diabetes, musculoskeletal disorders and some cancers (endometrial, breast, and colon). 1.6 million people can’t be wrong!

i-beat-anorexia.jpg

3. Drink alcohol! There are about 2 billion people worldwide who consume alcoholic beverages and 76.3 million with diagnosable alcohol use disorders. These numbers are still too low, please help improving them! Drink, drink and you can get closer to oesophageal cancer, liver cancer, cirrhosis of the liver, homicide, epileptic seizures and motor vehicle accidents.

4. Smoke! Some cigarettes a day, and you can send the doctor away. The list of the possible effects of smoking is so exciting: cancers of the bladder, oral cavity, pharynx, larynx (voice box), esophagus, cervix, kidney, lung, pancreas, and stomach. I nearly forgot about cardiovascular diseases and chronic obstructive pulmonary disease (the fourth leading cause of death in the USA).

5. Sunbathe! Chronic exposure to UV radiation causes erythema, sunburn or even melanoma, one of the deadliest diseases of the world. Try it! An easy and cheap method to suffer.

sunburn.jpg

6. Use more salt! More than 5 g salt a day and you don’t have to worry about high blood pressure. “It has been calculated that a 3g reduction in salt intake in the adult population would lead to a 22% reduction in stroke and a 16% reduction in chronic heart disease.” It means that a daily 15 g salt intake would lead to serious results…

saltad.jpg

7. Stay stressed! Is your work boring? Are you in a middle of a traffic jam? Try to stay tensed as the stress ulcus is the best friend of the stomach. The pain, the bleeding and the acid in your oesophagus shouldn’t make you interested. Oh, and depression, burnout syndrome are also in the packet.

8. Don’t wash yourself! Improper hygiene can lead to problems like dental caries, fungal infections, parasites and it’s even helpful in transmitting HPV (keyplayer in the cancer of the cervix) and other sexually transmitted infections.

hygiene-delayingyourvisitcomic2.gif
Source

9. Inherit bad genes! You obviously can’t control it. But if you would at least take a deeper look at your family history, you could try to prevent some kind of diseases (e.g.: gout or diabetes type II. with proper diet). So forget about it! Don’t let enthusiastic geneticists force you to think differently!

familytree.jpg
Source

10. Be creative! Travel to tropical countries (for malaria, tuberculosis and other hot diseases); don’t care about ticks (Lyme disease); do not eat vegetables and fruits (for colon cancer); work in a polluted place and especially think negative! It will definitely help.

I can write hundreds of posts here about web 2.0 and medicine (medicine 2.0, if you happen not to know about it) or genetic testing. But medicine starts at home. In many areas of medicine, we can’t control anything so at least we should take care about what we can take care about.

You can’t control the car rushing towards you without brake, but at least you can move two steps backward.

Grand Rounds 3.25

It’s my honor to host this week’s Grand rounds, the weekly rotating carnival of the best of the medical blogosphere. Medical students think alike: in preparing for this edition I came across an earlier Monty Python theme, The Holy Grail of GR at The Rumors Were True. Now, I decided to use some medicine and health care related Monty Python videos to provide funny moments while reading all the nearly 60 submitted articles.

I hope you’re going to enjoy this edition. Let’s start with one of my favourite subjects: from prenatal care to childhood. Also don’t miss the Python’s hospital sketch about a childbirth below:

  • Hsien Hsien Lei at Genetics and Health writes about Dr. Rav Dhallan of Ravgen and shares her thoughts on prenatal testing.
  • Health Observances blog examines the economic impact of birth defects, or the folic acid awareness.
  • Tales from the Womb presents Baby Toby Saga, a collaborative mini-series created with Dream Mom. The idea was to pilot a new form of short story on the blogosphere between a physician and a patient. Don’t miss any of the chapters.
  • Healthy Children’s post, Enhance Your Kids with Drugs, Machines, and Perfect Genes asks parents: which group will they choose for their kids: the enhanced or the ordinary?
  • Dr. Wes talks about a headline story, the relationship between trans fat and milk (Milk Might Be Harmful to Children).

Let’s continue with many bloggers’ main subject, diet from several aspects:

Mr. Gumby, in the Python video below, can’t find a nurse, but we always find the best posts of our favourite nurse bloggers:

Posts on Diabetes care:

Before watching a video on a hospital in which the doctors relax and the patients do all of the work, let’s see the usual health care section:

  • Dr. David Erani at HealthcareForum.com asks the big question: is death penalty disproportionately used against the poor?
  • Kevin, M.D. (1 doctor for 18,000 patients) and Universal Health (From Zero To Infinity And Beyond) both posted on military healthcare.
  • According to the Health Business Blog, Senators still seem to be missing the point on generic biologics.
  • Doc in the Machine describes new FDA programs which try to track drug safety and share data with the public.
  • MSSP Nexus Blog examines patient safety and mentions a book on how to build a safer health system.
  • Susan Palwick at Rickety contrivances of doing good is a volunteer ED chaplain and has written a post about the frustration of dealing with inappropriate parenting in the ED.
  • Transplant Headquarters tells us how to look up a transplant center.
  • A true story from The wait and the Wonder blog on miscommunication. For over 3 months, she thought her daughter was actively listed for a liver transplant, when she was, in fact, still listed as a status 7, inactive.
  • An other transplantation issue from A Chance to Cut is a Chance to Cure about the organ-transplant network.
  • Then The InsureBlog takes us into the far future where everyone will have access to free health care.

Our medical bloggers provided us with many interesting and instructive cases:

  • Val Jones, M.D. presents a story about a man who was bitten by a rabid bat. Did you know why rabies can cause “hydrophobia” in its victims?
  • Or did you know what is the correct way to remove a tick if it is embedded in a person or pet? Medicine for the Outdoors answers the question.
  • Odysseys of George’s first article is about an elderly lady with intestinal obstruction (fascinating images!); in the second one, he shows the sad part of medicine: death.
  • Parcho, MD knows well how to deliver a baby in medicine style.
  • Dr. Signout tells us a drug seeker’s story in the Gut reaction post.
  • And a terrible story in other things amanzi blog on sjambok syndrome.

Fun, musings, robotics and a strange video which proves that sometimes we can’t hear or see the patient even if it’s our fault. Consider this section as the editor’s choice:

I don’t know whether there have ever been an images’ section, but here it is:

At last, I hope I create a new section in the history of Grand rounds with medicine and web 2.0:

I hope you enjoyed this Grand rounds edition as I’ve had so much fun while doing it. Thank you, Nick Genes for the opportunity and all the help. Please prepare for the next edition at Blog, MD. Sorry for the irking medical Monty Python videos, but I must say that thank you for watching and good night a dingdingdingdingding…

Genes modified by diet

The importance of epigenetics is still rising. A recent study, published in the journal Proceedings of the National Academy of Sciences, has shed light on a biological mechanism that could explain why some of us appear “programmed” to put on weight.

But before you blame grandma for your health, epigenetic inheritance of obesity has not been observed in humans at a molecular level, although the mechanism could explain patterns of obesity and diabetes seen in populations whose ancestors had a poor diet.

The researchers used a unique strain of mouse with a variant of a gene, called agouti viable yellow, that is not found in humans. When switched on, the agouti gene is associated with yellow fur, obesity, diabetes and cancer… Feeding pregnant mice a nutrition supplement switched off the agouti viable yellow gene.

“The novel thing is that when we bred the offspring of the supplemented mice, which had never seen the nutritional supplement, their offspring were also more likely to be brown and lean. The finding shows that diet can affect gene expression and that can be heritable.”

I asked Trevor R. Covert, a Genetics/Cell Biology student at Epigenetics News to comment on this finding.

Update: Trevor sent me his opinion:

I think these findings are very important in advancing our understanding of how the epigenome may affect our health and our susceptibility to disease. I have blogged about some epigenetic transgenerational research in the past, including the research out of Dr. Michael Skinner’s lab (where I work) at Washington State University.

New Research: Epigenetic Transgenerational Adult-Onset Disease

I have also blogged about similar research with the agouti mouse model out of the lab of Dr. Robert Waterland at the Baylor College of Medicine.

Nutrition During Pregnancy and Its Transgenerational, Epigenetic Effects

In my opinion, in the next few years it will likely become apparent that other nutritional items and chemical toxicants will be found to have similar effects. It will be an interesting phenomenon to watch, and one that could
have broad implications for our understanding of how our environment is affecting human health.

Morning Baby News

Here are the best baby, pregnancy related articles, findings from the last 24 hours :

Children whose mothers were stressed out during pregnancy are vulnerable to mental and behavioural problems like ADHD, mounting evidence suggests… We should be screening women in pregnancy for stress and intervening. It has big public health implications. About a million children in the UK have neurodevelopmental problems – ADHD, cognitive delay, anxiety and so on. About 15% of this might be due to antenatal stress.

A new study finds that women who take folic acid supplements early in their pregnancy can substantially reduce their baby’s chances of being born with a facial cleft… The researchers estimated that 22 percent of isolated CLP cases in Norway could be averted if all pregnant women took 0.4 mg of folic acid per day.

In the wake of a new record for becoming the world’s oldest mother, fertility experts are encouraged by recent research showing that older moms are as capable of good parenting as younger women — but are increasingly concerned about women naively postponing pregnancy till later in life.

Then here is a not so active Health games blog:

The Serious Games Initiative founded Games for Health to develop a community and best practices platform for the numerous games being built for health care applications.

It’s never too early to start playing with medical games. Kids, take a look at the Body scavanger and the Mission Nutrition.
