When reports arrived that accused gunman Jared Lee Loughner had opened fire in Tucson, Arizona on January 7, journalistic first responders linked the incident to the fierceness of political rhetoric in the United States. Upon reflection, some of the discussion has turned to questions about mental illness, guns, and violence.
And plenty of reflection is required, because the connections are not at all simple. To get a sense of just how complicated they are, we invite you to read the lead article in this month’s Harvard Mental Health Letter entitled, “Mental Illness and Violence.” Strangely (for us) it was prepared for publication a month before the tragedy in Tucson. In light of the shooting, we are making the article available to non-subscribers.
I am not surprised at the outrage expressed in the news or at the impulse to blame. A quick scan of the news, however, shows there is not much agreement about whom to blame. In addition to the alleged perpetrator, one can find explicit and implicit criticisms of politicians for playing to our baser instincts; of media figures, various men and women of zeal, for their disingenuous or manipulative partisanship; of the various community bystanders (police, teachers, doctors, family members, neighbors, friends), whom we imagine could have intervened to prevent tragedy.
The political debate flowing from this incident will continue, as will the endless cycle of blame and defensiveness. But I caution all of us — and especially mental health professionals — not to make clinical judgments about Mr. Loughner. Very few people will or should have access to the kind of information that would allow such judgments. From a public health perspective, however, we should make careful judgments about policies that could reduce risk. Read more »

One of our readers suggested that I review the book The Great Influenza: The Epic Story of the Deadliest Plague in History, by John M. Barry. It’s not a new book (it was published in 2004) but it is very pertinent to several of the issues that we have been discussing on this blog, especially in regards to the current anti-vaccine movement. It’s well worth reading for its historical insights, for its illumination of the scientific method, and for its accurate reporting of what science has learned about influenza.
In the great flu epidemic of 1918, influenza killed as many people in 24 weeks as AIDS has killed in 24 years. It’s hard to even imagine what that must have been like, but this book helps us imagine it. It tells horror stories: Children found alone and starving beside the corpses of their parents in homes where all the adults had died, decomposing bodies piling up because there was no one left who was healthy enough to bury them.
Sometimes the disease developed with stunning rapidity: During one three-mile streetcar trip, the conductor, three passengers, and the driver died. In another incident, apparently healthy soldiers were being transferred to a new post by train: During the trip, men started coughing, bleeding, and collapsing; and by the time it arrived at its destination, 25 percent of the soldiers were so sick they had to be taken directly from train to hospital. Two-thirds of them were eventually hospitalized in all, and 10 percent of them died. The mind boggles. Read more »

Not all maternal influence on daughter behavior is good. Take for example the influence of the unhealthy use of indoor tanning beds as presented in a recent Archives of Dermatology article (full reference below) which “investigated whether indoor tanning with one’s mother the first time would influence frequency of tanning later in life and whether it was associated with age of initiation.”
Joel Hillhouse, Ph.D., of East Tennessee State University-Johnson City and colleagues published a study the May 2010 issue of the Archives of Dermatology which looked at which health-based intervention worked best in reducing skin cancer risks. They found that “emphasizing the appearance-damaging effects of UV light, both indoor and outdoor, to young patients who are tanning is important no matter what their pathological tanning behavior status.”
For this study, Hillhouse and colleagues randomly selected a total of 800 female students who were then sent a screening questionnaire on their indoor tanning history. Those who reported ever indoor tanning (n = 252) were invited to participate in the study and offered an incentive ($5). A total of 227 (mean age, 21.33 years; age range, 18-30 years) agreed, signed informed consent documents, and completed assessments.
One of the questions asked who accompanied the participant the first time they indoor tanned (i.e. tanned alone, with friend, with mother, or other). Read more »

Intraocular pressure is usually measured by applying a force on the cornea using a tonometer. Although sufficiently accurate, tonometers are only used in ophthalmologist offices and so don’t measure intra-day pressures. They also fail with people post cataract surgery that have a thicker cornea. Researchers at University of Arizona have developed a new device that measures intraocular pressure through the eyelid.
From the University of Arizona College of Engineering:
The self-test instrument has been designed in Eniko Enikov’s lab at the UA College of Engineering. Gone are the eye drops and need for a sterilized sensor. In their place is an easy-to-use probe that gently rubs the eyelid and can be used at home.
“You simply close your eye and rub the eyelid like you might casually rub your eye,” said Enikov, a professor of aerospace and mechanical engineering. “The instrument detects the stiffness and, therefore, infers the intraocular pressure.” Enikov also heads the Advanced Micro and Nanosystems Laboratory.
While the probe is simple to use, the technology behind it is complex, involving a system of micro-force sensors, specially designed microchips, and math-based procedures programmed into its memory.

Emerging economies must act immediately to halt rising obesity rates before the epidemic becomes as severe as it is in first-world countries, according to new report by the Organization for Economic Cooperation and Development (OECD).
The OECD report was published in the Lancet. It characterizes the prevalence of obesity in Brazil, China, India, Mexico, Russia and South Africa. Obesity rates were found to vary dramatically across these six countries. In Mexico, a stunning 70 percent of adults were reported to be overweight or obese. Nearly half of all Brazilians, Russians and South Africans fell into these categories. China and India had a lower prevalence of overweight and obesity, but were moving rapidly in the wrong direction, according to the OECD.
Developing nations don’t have enough resources to handle the health consequences of obesity, which include an increased risk of cardiac disease, stroke, cancer, diabetes, arthritis, and disability from all causes.
