Who’s Your Daddy? Low Tech Paternity Testing

I was perusing Dr. Hsien Hsein Lei’s blog and noticed a link to a pretty interesting tool.  Dr. Lei describes it as a “low tech paternity test” and it’s a probability calculator that relies on 3 traits: blood type, eye color, and ear lobe type.  Yep, it’s sometimes possible to exclude certain father candidates based on these traits.

Apparently attached earlobes (that don’t hang) are a recessive trait, so if a child has unattached earlobes, both parents can’t have attached earlobes.  And as far as eye color is concerned, two blue eyed parents can’t have a brown eyed child – so there’s some opportunity for exclusion there (I was interested to see that two dark brown eyed parents can have a blue eyed child, though it’s rather unlikely).

Did you know about the genetics of ear lobes?  I learn something new every day.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.

Tuberculosis and Badgers

This was one of the strangest news items in my inbox this week.  Apparently, British cattle are catching tuberculosis from the local badger population.  Now, the only thing that I thought the two animals had in common was their coloring… but I guess they must hang out together with sufficient frequency to pass on TB infections.

In fact, one BBC News report suggests that farms with larger hedges had lower rates of cattle TB infections… presumably because the hedges kept the badgers from fraternizing as much with the cows.  This finding provides a nice alternative to badger culling, a practice that the animal rights folks do not endorse.

But what does this mean for humans?  Well, according to the CDC, cattle TB (caused by a special strain of mycobacterium – M. bovis) has been virtually eradicated in the US due to herd culling and milk pasteurization methods.  Cattle TB doesn’t tend to infect the lungs, so it’s less transmissible via droplets and such.  So even if you’re in England and Bessy the cow sneezes on you, you probably won’t catch TB.  But if you drink Bessy’s unpasteurized milk or cheese products, you’ve got yourself a risky situation.  As for badgers – they’re not very affectionate anyway, so I wouldn’t try to befriend them.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.

Healthcare Blogger Code of Ethics

In response to recent concerns about healthcare blogging (potential privacy violations in particular), a group of bloggers got together to create the first Healthcare Blogger Code of Ethics.  All health bloggers who agree to abide by the ethical principles listed in the code will be given the HBCE seal to display on their blogs.  If anyone suspects the bloggers of violating that code, they can be reported to the HBCE website for further investigation.

I think this is a great step forward for health blogs – and a good reminder to respect confidentiality, transparency, and courtesy while blogging.  To request a copy of the seal for your blog, please write to: healthcare.bloggers@gmail.com

Many thanks to Dr. Rob for taking the lead on this project.  Also thanks to Medi-mation who worked on the logo with me.

The 5 principles:

  1. Clear representation of perspective – readers
    must understand the training and overall perspective of the author of a
    blog. Certainly bloggers can have opinions on subjects outside of their
    training, and these opinions may be true, but readers must have a place
    to look on a blog to get an idea of where this author is coming from.
    This also encompasses the idea of the distinction between advertisement
    and content.  This does not preclude anonymous blogging, but it asks that even anonymous bloggers share the professional perspective from which they are blogging.
  2. Confidentiality – Medical bloggers must
    respect the nature of the relationship between patient and medical
    professionals and the clear need for confidentiality. All discussions
    of patients must be done in a way in which patients’ identity cannot be
    inferred.
  3. Commercial Disclosure – the presence or
    absence of commercial ties of the author must be made clear for the
    readers. If the author is using their blog to pitch a product, it must
    be clear that they are doing that. Any ties to device manufacturer
    and/or pharmaceutical company ties must be clearly stated.
  4. Reliability of Information – citing sources when appropriate and changing inaccuracies when they are pointed out
  5. Courtesy – Bloggers should not engage in
    personal attacks, nor should they allow their commenters to do so.
    Debate and discussion of ideas is one of the major purposes of
    blogging. While the ideas people hold should be criticized and even
    confronted, the overall purpose is a discussion of ideas, not those who
    hold ideas.

Happy blogging!This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.

Medscape’s Pre-Rounds Interview With Dr. Val

I was recently interviewed about my blog (and this week’s edition of Grand Rounds) by Dr. Nick Genes at Medscape.  For the curious among you – here is the full Medscape interview with Nick Genes (prior to editing).  It gives you a little more information about Revolution Health…

1.      You’ve
been involved in writing since medical school, for various audiences. Who are
you trying to reach with your new blog, and how have you found blogging to be
different than the other media you’ve worked in?

The best part about
blogging is that it’s a dialogue rather than a monologue.  I find the interactive discussions and
heartfelt responses to be touching and engaging.  My previous writing was more academic because
of the medium (medical journals) but now I’ve found that blogging is where I
can really be myself – there is no team of reviewers to scrub my words.  So what you read is what you get!

2.      I’m
very curious about Revolution Health, your role as Senior Medical Director, and
where you think this is all going. But all revolutions have their origins
somewhere, and yours seems to start… on a yogurt farm. Please share a little
of what that was like, and maybe what early influences have given you such an
interesting background. From small towns to New York City, from theology to medicine, it
seems like you’re living a very rich life.

Yes, I guess you could
say that my origins as a revolutionary are firmly rooted in dairy farming.  Although it may not be immediately apparent
how the two are related, Internet startups and cattle herding have their similarities.  First, you have to wear many hats – there is
no job too small or too large.  If the
cows need milking, and the electric machines are broken, you do it by hand.  If a cow breaks through the fence and wanders
off into town, you lure her back with short feed.  If a large batch of yogurt curdles, you’ve
got yourself a gourmet meal for your pigs… you get the drift.  In a large start up, all manner of unexpected
events happen – but the trick is to handle them quickly and efficiently, and
make sure the outcome is a win-win.

As far as my other
life detours… I guess you can say that I’ve been a victim of my own
curiosity.  There are so many interesting
things going on, I just can’t help but want to try them out.  In the past I’ve held jobs in the following
capacities:

A protestant minister,
NYC bartender, bank spy, food critic, doctor, cartoonist, computer sales
associate, yogurt mogul, nanny, motivational speaker, biophysics researcher,
graphic designer and revolutionary medical director.

So my life has
certainly been an adventure!

3. How did you get involved with this company? Did Steve
Case find you, or know you from before — or was there an application process?
Is the mingling of medical and computer technology folks going smoothly? Is it a
mix of hospital culture vs. laid-back internet start-up culture? (Foosball and
mountain bikes, or suits and meetings?) Can you make comparisons to your time
with MedGenMed?

A friend of mine had
interviewed at Revolution Health for an executive position and thought that the
company would be a great fit for me.
When I heard who was involved (including Colin Powell, Steve Case, Carly
Fiorina) and that the goal was to create a website  to help patients navigate the health care
system, I thought – gee, this sounds serious, challenging and worthwhile.  So I sent in my resume, got offered an
interview, put on a bright red suit and announced that I’d heard that there was
a revolution afoot and wondered where I could sign up.  They hired me that same day (May 8, 2006) and
it’s been the most exciting job I’ve had to date!

About the “mingling”-
a very interesting question.  There is a
hint of Foosball/mountain bike in the mix, but I think we’re a little more hard
driving than that.  Since Revolution
Health is in its start up phase, there is simply too much work to do for people
to be playing Foosball.  When I started,
there were 30 employees, now there are closer to 300.  We are all working long hours on cutting edge
projects that I believe will make a big difference in supporting the
physician-patient relationship, streamlining the process of healthcare delivery
and improving accessibility to the uninsured and underinsured.  Revolution has attracted some of the
brightest minds in the tech industry – and they are building products I could
never have dreamed of on my own. Since I have such an unusual background,
I’m  bilingual in both techie speak and
physician speak, and this helps a great deal.
Because I understand what physicians and patients need, and can translate
that for the “creatives” we can build some really meaningful tools and products
together.

My time at MedGenMed
was wonderful, primarily because Dr. George Lundberg is a dear friend and
mentor.  He has done fantastic work
creating a pure platform (no pharma influence or fees for readers or authors)
for open-access publishing.  He taught me
to speak my mind, follow my gut and never compromise my ethics.  His book, “Severed Trust” galvanized me into
action – to do my part to improve the damaged physician-patient relationship
that is at the core of our broken system (caused by middle men, volume
pressures and decreased time with patients).
After reading his book, I wanted to do something big – so I joined a
revolution.

3.      Revolution
Health has some bold ideas about improving care for its members — getting
appointments with specialists, patient advocacy in dealing with insurance, and
of course, sharing information. What’s your job entail, as medical
director? Do you think you’ll find yourself making policy decisions that
could affect, directly or indirectly, chunks of the population? Could
you find yourself in a position where some specialists are not recommended
based on their insurance? Will Revolution Health have a formulary, will it
be evidence-based — or could could care be rationed ?

My job is incredibly
challenging and fun, and I rely on both halves of my brain for much of what I
do.  We have 146 medical experts most of
whom I’ve personally recruited, I’m responsible for coordinating the medical
review of all the content on our portal (so that it conforms with
evidence-based standards), I facilitate relationships with major hospital
systems (such as Columbia University Medical Center), spearhead new product
initiatives (such as Health Pages for physicians), monitor and promote our 30+
expert bloggers, participate in writing press releases, creating podcasts, radio interviews,
identifying new partnership opportunities and much more.

I do think that
Revolution Health will greatly influence vast “chunks” of the population.  And this is what’s particularly exciting
about working here.  We really are
building a brand new navigational system for healthcare – and this will empower
patients to take control of their health and provide them with better
information and guidance in living their best.
I believe that Revolution Health will become the new virtual medical
home for physicians and patients, just the way that AOL grew to be America’s
Internet home.  You log on first to AOL
to get your email, check your news, and get plugged in before surfing the
net.  You’ll log in to Revolution Health
to track your health, connect with your lifestyle coach or physician guide, get
involved with a community of others like you, or track your loved ones’ health
issues through Care Pages.  This is a 20
year project, so all of our plans and programming may not be apparent yet, but
the trajectory is amazing and I wouldn’t want to be anywhere else as a
physician today.

5. What are some of your favorite posts — something that
struck a nerve with readers, or captured something you wanted to express?
Please provide links!

My absolute favorite
post
is the story of how my mom, a strong patient advocate, saved my life as a
baby.  She refused to accept the
misdiagnosis I was given, and continued to nag the medical team until they
realized what was wrong and took me to the O.R.
If it hadn’t been for her persistence (or the incredible skill of the
surgeon who ultimately took care of me), I wouldn’t be here today.  And maybe that’s why I’m passionate about
both good medical care AND patient empowerment!

Other posts that have
been well received are true stories from my medical training days.  Some are controversial (like this one about
end of life issues and my first day as a doctor),
and others are warmer reflections.  But ultimately, I just share what’s on my
heart and let the audience take away what they can from it.

The Truth About Cellulite

It’s funny how cultures become obsessed with certain physical attributes.  In the middle ages warts confirmed the identity of witches, a gap between the front teeth was considered pleasing, and a “heart shaped face” was the epitome of beauty.  This past century we’ve vacillated between pleasantly plump to “rail thin” as a standard of loveliness… and in recent years women have become preoccupied with a new menace: cellulite.

Of course, no one had even noticed cellulite until the French coined the term 150 years ago.  And unhappily that plague crossed the Atlantic in the 1960s, terrorizing pleasantly plump beauties from that day forward.

An entire industry has sprouted up to combat this dimpled foe – everything from massage to liposuction to caffeinated lotions claim that they will restore a smooth appearance to irregular thighs.  Unfortunately, those promises are all empty.

Yes, that’s right – there is no research to suggest that any cellulite treatment has anything but the most modest of effects.  The bottom line is that dimply skin is determined by your genes – same as your eye color – and that the majority of women have some degree of cellulite no matter how thin they are.  Sure, estrogen can play a role – but basically there’s no escaping estrogen as a woman!

So if you’re one of those people who is a little more dimply than average – here’s what you can do:

1.  Wear clothes that cover the dimples.  Spanx and biker shorts can be worn underneath trousers and longer skirts to give a smoother appearance.

2.  Adjust the lighting in your bedroom and bathroom – diffuse light doesn’t reflect shadows from skin imperfections as much.  It’s amazing how lighting can emphasize (or de-emphasize) cellulite.

3.  Stay fit and tone your body as much as possible.  That way if the rest of your body is lean and firm, the cellulite won’t be that big a deal.

4.  Recognize that you will always have cellulite.  It’s not your fault, you didn’t cause it and you can’t solve it.  Don’t waste your money on creams and treatments that don’t work.

5.  Remember that the vast majority of guys don’t even notice cellulite (it’s virtually invisible due to their fixation on other anatomical parts).

6.  Blame it on the French.  If you fixate on your cellulite you are letting them win!  Show those French your best laissez-faire attitude by completely ignoring this “disease” that they concocted.

I vote that we go back to the days before the invention of cellulite and live a carefree, confident existence.This post originally appeared on Dr. Val’s blog at RevolutionHealth.com.
