From the WSJ:
Our average attention span halved in a decade, from 12 to five minutes. To combat this, a "museum intervention" is now mandatory at Yales School of Medicine for all first-year medical students. Called Enhancing Observational Skills, the program asks students to look at and then describe paintings—not Pollocks and Picassos but Victorian pieces, with whole people in them. The aim? To improve diagnostic knack.
The Waterseller of Seville, 1618-1622, Oil on canvas. This is not considered an example of the "Victorian pieces" mentioned in the WSJ article. Image source: Wikipedia, public domain.
Each student is assigned a painting which they examine for 15 minutes, recording all they see. Then the group discusses its observations.
"We are trying to slow down the students. They have an urge to come up with a diagnosis immediately and get the right answer."
The study did not provide a huge improvement in the diagnostic acumen though. After the completion of the study project, the medical students were 10% more effective at diagnosis. Nonetheless, the program has now expanded to more than 20 U.S. medical schools. The evidence behind this intervention is not very convincing.

Mike Moore: Interesting. Whats the reference for "Attention span halved in a decade, from 12 to 5 minutes"
Ves Dimov, M.D.: The reference is the text: "Our average attention span halved in a decade, from 12 to five minutes, according to a study commissioned by Lloyds TSB Insurance. (And that was in 2008.)" I havent checked the source beyond the referenced WSJ article in this case.
Mike Moore: Sorry, that was a bit of a rhetorical question. This is the best I could find, it doesnt appear to be an actual published study... http://www.insurance.lloydstsb.com/personal/general/mediacentre/homehazards_pr.asp
Mike Moore: Even better, here is an analysis of when the "data" was initially released in 2008. http://neuroskeptic.blogspot.com/2008/11/spooky-case-of-disappearing-crap.html [The link to David Moxon, the "researcher" who was commissioned by Lloyds to do the study is now dead, replaced with a generic landing page. I guess he doesnt do "Psychological Research" anymore.]

According to the "World Happiness Report", the happiest people in the world live in Denmark, Finland and Norway. The report is published by the United Nations (the first edition was in 2012).
According to one of the people interviewed, its all an expectations game: "We dont expect much from life in Denmark, and we are happily surprised when something goods happens." (quote from memory). I doubt that it is that simple. Here is the Deutsche Welle video:
The top 10 happiest nations on the planet are:
1. Denmark
2. Finland
3. Norway
4. Netherlands
5. Canada
6. Switzerland
7. Sweden
8. New Zealand
9. Australia
10. Ireland
Happier countries tend to be richer countries. Over time as living standards have risen, happiness has increased in some countries, but not in others (like for example, the United States). On average, the world has become a little happier in the last 30 years (by 0.14 times the standard deviation of happiness around the world).
Stable family life and enduring marriages are important for the happiness of parents and children. In advanced countries, women are happier than men, while the position in poorer countries is mixed.
Happiness is lowest in middle age.

How Twitter is Changing the Job Hunt. Some recruiters say Twitter has transformed their prospecting and hiring, helping them identify candidates they wouldnt have found otherwise, but others say the messaging platform has some way to go before it can replace LinkedIn, Facebook or other job-hunting tools.

A study by the producer of Kleenex, Kimberly-Clark, found that the 6 "Dirtiest Places" in Your Office are:
- break room sink-faucet handles
- microwave door handles
- keyboards
- refrigerator door handles
- water fountain buttons
- vending machine buttons
And dont forget that the "Five Second Rule" doesnt work, says Dr. Susan Rhem, an infectious disease specialist from the Cleveland Clinic:
A common superstition, the five-second rule states that food dropped on the ground will not be contaminated with bacteria if it is picked up within five seconds of being dropped (Wikipedia).

LOGIC IS NOT GOOD ENOUGH. WE NEED EVIDENCE. WHY SHOULD PERFORMANCE MEASURES RECEIVE A PASS ON EVALUATION?
We once thought it was logical to give antiarrythmic drugs to patients after they had a myocardial infarction. We once thought that beta blockers were contraindicated in systolic dysfunction. We consistently follow logic and conventional wisdom, yet find out that we were wrong. Why should performance measures receive a pass on evaluation? From dbs Medical Rants: http://buff.ly/16uF3j7
HAS TWITTER CHANGED? REMEMBER WHEN TWITTER WAS A GREAT PLACE TO HAVE CONVERSATIONS?
When people now want to have a little bit deeper discussion, they send me an e-mail, or even a text to my phone - and the conversation takes place off the "public" airwaves. But why?
In my opinion, here are reasons why "rich engagement" has gone private: Political Correctness prevents deep analysis; This hyper-partisian world leaves little room for the "middle of the road" opinion; Being taken "out of context" is no longer the exception, it is the rule.

CHOOSE WISELY WHEN CHOOSING WISELY http://buff.ly/Wrjs4S
From NBC: "You don’t need an MRI for lower back pain. You don’t need antibiotics for a sinus infection. And you don’t need to be screened for osteoporosis, either, if you’re under 65. A list of 90 medical ‘don’ts.’"
Based on the headlines, one might think that these tests or treatments should never be done. However, this is not what the experts were saying. These are commonly overused tests and treatments, not useless.
CAN COMPUTERS REPLACE PHYSICIANS? http://buff.ly/WriSUx -- Why we need physicians rather than computers http://buff.ly/WriNAn
Computers might be great if we humans were identical. They might be great if our patients were accurate historians without unknown agendas. But none of those, and many other restrictions exist. We have to weigh each piece of evidence, especially the history. We use complex illness scripts and our experience.
Excellent doctoring requires knowledge (computers can provide) plus wisdom. How can we program wisdom?

Americans overdosing on salt - Author Michael Moss talks about our addiction to salt, and how the food industry develops our taste for it.
From Amazon:
"From a Pulitzer Prize–winning investigative reporter at The New York Times comes the explosive story of the rise of the processed food industry and its link to the emerging obesity epidemic. Michael Moss reveals how companies use salt, sugar, and fat to addict us and, more important, how we can fight back.
Every year, the average American eats 33 pounds of cheese (triple what we ate in 1970) and 70 pounds of sugar (about twenty-two teaspoons a day). We ingest 8,500 milligrams of salt a day, double the recommended amount, and almost none of that comes from the shakers on our table. It comes from processed food. It’s no wonder, then, that one in three adults, and one in five kids, is clinically obese. It’s no wonder that twenty-six million Americans have diabetes, the processed food industry in the U.S. accounts for $1 trillion a year in sales, and the total economic cost of this health crisis is approaching $300 billion a year.
In Salt Sugar Fat, Pulitzer Prize–winning investigative reporter Michael Moss shows how we got here. Featuring examples from some of the most recognizable (and profitable) companies and brands of the last half century—including Kraft, Coca-Cola, Lunchables, Kellogg, Nestlé, Oreos, Cargill, Capri Sun, and many more—Moss’s explosive, empowering narrative is grounded in meticulous, often eye-opening research.
Moss takes us inside the labs where food scientists use cutting-edge technology to calculate the “bliss point” of sugary beverages or enhance the “mouthfeel” of fat by manipulating its chemical structure. He unearths marketing campaigns designed—in a technique adapted from tobacco companies—to redirect concerns about the health risks of their products: Dial back on one ingredient, pump up the other two, and tout the new line as “fat-free” or “low-salt.” He talks to concerned executives who confess that they could never produce truly healthy alternatives to their products even if serious regulation became a reality. Simply put: The industry itself would cease to exist without salt, sugar, and fat. Just as millions of “heavy users”—as the companies refer to their most ardent customers—are addicted to this seductive trio, so too are the companies that peddle them. You will never look at a nutrition label the same way again."

WHAT IS ACUTE OTITIS EXTERNA?
Acute otitis externa is a common condition involving inflammation of the ear canal. It is caused by bacteria such as Pseudomonas aeruginosa and Staphylococcus aureus. Acute otitis externa often occurs following swimming or minor trauma from inappropriate cleaning.
WHAT ARE THE SYMPTOMS OF ACUTE OTITIS EXTERNA?
The rapid onset of ear canal inflammation leads to otalgia (earache), itching, canal edema, erythema, and otorrhea. Tenderness with movement of the tragus or pinna is a classic finding.
WHAT IS THE TREATMENT FOR ACUTE OTITIS EXTERNA?
For uncomplicated cases, use topical antimicrobials or antibiotics such as acetic acid, aminoglycosides, polymyxin B, and quinolones. Some of these agents come in preparations with topical corticosteroids which may help resolve symptoms more quickly.
There is no evidence that any one antimicrobial or antibiotic preparation is clinically superior to another. Here two suggested approaches:
- Neomycin/polymyxin B/hydrocortisone preparations are a reasonable first-line therapy when the tympanic membrane is intact.
- Oral antibiotics are used when the infection has spread beyond the ear canal or in patients at risk of a rapidly progressing infection.

With the help of a science lab, the filmmaker Casey Neistat found that calorie listings on food labels can be highly inaccurate - mostly underestimating the amount of calories in food products such as muffins, sandwiches, burrito, etc.
He selected 5 items he might consume in an average day: a muffin, a tofu sandwich, a Subway sandwich, a Starbucks Frappuccino and a Chipotle burrito. Then, two food scientists tested the caloric content of each using a device called a calorimeter. It’s a precise but slow process — taking more than an hour per sample. The results were surprising.
Four out of the five items had more calories than their labels reported, adding up to 550 calories. If he unknowingly consumed those extra calories every day, in a week he would put on an extra pound of body weight.
