Social Media Revolution 2011 Video

The new video featuring interesting pieces of information about the ongoing social media revolution is out:

Health 2.0 News: Centrifuge for Labor and Behind

At the moment the sensitivity and specificity of a lot of genetic tests for complex, polygenic disorders (for which we haven’t yet identified all the genetic variants that increase risk) are unlikely to match those of standard diagnostic or screening tests.  What’s likely is that the predictive capacity of these tests will improve as more variants are identified, and/or if additional non-genetic information is included in the test.

Science and Social Media News: Nature comments and Wikipedia books

  • Content rules: Nature opens up content for comments and discussions.

‘Conversation is king’, according to a mantra frequently repeated by enthusiasts of online social media. But we editors and writers tend to give our first allegiance to content — not least because of our labours to research, commission, select, create and otherwise add value to content, and to do so in a way that informs and stimulates our readers: the people who pay for it.

But, unquestionably, conversation can add value to such efforts. Therefore, this week we introduce an online commenting facility that will allow readers to respond directly to any of our content.

Existing metrics have known flaws
A reliable, open, joined-up data infrastructure is needed
Data should be collected on the full range of scientists’ work
Social scientists and economists should be involved

20 Impressive Internet Statistics

I guess everybody knows the Did you know video series focusing on different internet-related statistics, but this one is really spectacular and unique.

Worldometers: Real Time Health Statistics

Worldometers is quite an interesting project. It shows important statistics in real time including world population, energy consumption or Internet users in the world.

The counters that display the real-time numbers are based on Worldometers’ algorithm that processes the latest and most accurate statistical data available together with its estimated progression to compute the current millisecond number to be displayed on each counter based on the specific time set on each visitor’s computer clock.

But it also highlights real time health-related data:

H1N1 vs Tuberculosis

My friend, Francisco Grajales III shared this great video with me. Hans Rosling has something very important to say about H1N1:

13 days H1N1 Tuberculosis (TB)
Death 31 63 066
News 253 442 6 501

Check his wonderful TED presentation out as well.

Twitter Charts

Twitter, the microblogging service, is one of the most useful online tools these days. There is a whole community focusing on health 2.0 and medicine 2.0.

Now you can track your statistics as well. I use TweetStats for this purpose that shows my tweetcloud (words I use often):


And here is how often I twit…


Or you can try Twitter Charts:

World Clock: What’s happening right now in global health?

World Clock is a Poodwaddle application that tells you how many babies are being born at this very moment or how many people have died from cancer. It also includes data regarding injuries, non-communicable and infectious diseases.

The stats provided here are approximations based on figures from World Health Organization, CIA Factbook, US Census Bureau, and other sources. Wherever possible we have verified the figures. However, due to the contradictory and dynamic nature of much of the data, we cannot guarantee their accuracy.


Medicine 2.0 linkfestival

Web 2.0 + medicine = medicine 2.0. You must have read the BMJ article: How Web 2.0 is changing medicine. I’ve been searching for med 2.0 links for days now, and I hope you’ll like them. Some of them will definitely be known, but some must be new. Let’s start with two studies:

According to the Pew Internet & American Life Project, about 113 million U.S. residents searched for health care information online in 2006, and eight million individuals search online daily for information about diets, diseases and physicians.

After demonstrating last year that medical students greatly improved their stethoscope skills by listening repeatedly to heart sounds on their iPods, lead investigator Michael Barrett, M.D., clinical associate professor of medicine and cardiologist at Temple University School of Medicine and Hospital, set out to test the technique on practicing physicians.

Me, I’m just installing the Diagnosaurus on my PDA…

A site for searching, but you can request for live assistance. I tried it and I got relevant information on Brugada syndrome. As they say: ChaCha combines the best of the web’s search engines with the human intelligence made possible by a vast community of skilled search experts.

It started with a simple observation: physicians need easier access to patient information. Since then, PatientKeeper has grown to become the leading physician information system provider: to review electronic patient records…write prescriptions…enter charges…dictate notes…document encounters…place orders…even consult with other caregivers.


The aim is to extend the programs currently offered online to librarians and library users to the Second Life virtual reality game. Although there are a couple of libraries currently on Second Life, none currently offers programs or services.

The second part of this post is coming soon. Thank you for watching!

A miraculous blogstory: how to get 120,000 visitors in one day?

I tell you the story of my blog’s recent success. Since the start in November, I’ve been struggling to reach a number of readers of about 300 and 20 feedreaders. And then, on Thursday, before going to the cinema, I decided to submit one of my most successful posts (The youngest mother) on to see how many users would come to my site. After coming home (the film, Blood Diamond was fantastic), I saw that 1,200 users clicked on that post from reddit. I was very content, then I went to sleep…

Next morning shock: 50,000 readers and the number was still growing! What happened? Somebody dugg my reddit post. It’s not a big deal as I’ve already dugg it in December but in the Health category. This time, this user dugg me in the Off-beat category (summary: 3892 diggs) and I finished the day with a splendid number of 118,000 readers and more than 6000 feedreaders. I got more than 40 links from 30 blogs in just one day. Scienceroll was the No. 1 at and Take a look at my stat images. Ridiculous, aren’t they?

My most visited posts

How and why did it happen to me?

  1. The most important point, I was lucky.
  2. I used reddit to popularize a successful, but old post of mine.
  3. I’ve been dugg at the best time, in the best category.

What could I do to make it happen again?

  1. If a medical blogger wants his/her words to reach a great audience, then he/she must write some kind of popular medicine related articles aside from the real medical, scientific ones.
  2. We have to popularize these articles.
  3. Sometimes just pick one of your old, but successful posts, clean and improve them with interesting videos, news and digg or submit it on reddit. (I did the same with my article Fighting cancer with video games and I’ve been mentioned in 3 blog carnivals – including Grand rounds and Mendel’s Garden – and several blogs such as Kevin, MD.)


  1. Even if I write mostly about medicine, hardcore clinical genetics and diseases, sometimes I have to provide interesting and weird content to get more readers.
  2. I must be more experienced about how to use web 2.0 tools to popularize medicine.
  3. And I still have to keep up the hard work, post every day and if possible, find treasures like the youngest mother.
