Reinventing Seniors' Health

Visions for Aging and Health

To improve seniors' cognitive, physical and emotional health [“A New Age for Old Age,” Spring 2007], we must understand their needs. Many seniors do not want to trouble their adult working children, so they don't discuss their medical, social, emotional and economic needs. It becomes the duty of the caretakers to understand their seniors. They do not need big expensive things. They only need a little attention. Pets get so much love and attention—can't we give half of it to our seniors?

Social interaction during later years is sure to have tremendous effects on the lifestyle of older people. This helps to improve their food habits as they meet for a meal and take their time to eat, take walks at a pace they are comfortable with and make good conversation!

One sure shot way for the older to keep healthy physically is by the regular practice of yoga. It not only helps improve physical fitness but also enhances mental and emotional well- being. It has gathered tremendous momentum among the senior population in India as they become increasingly aware of its benefits.

Making a Clear Point

A quick point about “The Science of Small” [Spring 2007]. You state that "Nanoparticles like titanium dioxide are already used in sunscreen lotions to filter out harmful ultraviolet light." This statement is true but misleading. Titanium dioxide has historically been used in sunscreens to filter ultraviolet light. However, nanoscale titanium dioxide is used because at that scale the applied formulation is "clear" (as opposed to the "white" color of products containing conventional titanium dioxide). One could misinterpret that nanoscale titanium dioxide "increases" protection from ultraviolet light. Such is not the case.

Journey to the Center of the Fold

I loved the Spring 2007 centerfold, “The Genetic Journey: Following DNA from Cell to Society.” The graphic was thorough, enlightening and easy to follow. Kudos to its creators.

Due to incorrect information provided to the Magazine, Fernando Montenegro Torres, PhD '04, was included in the Spring 2007 list of recent deaths. Soon after publication, we learned that—happily—he is alive and well. We deeply regret both the error and the dismay that it caused colleagues and friends.

"Making Markets for a Much-Needed Vaccine" (Spring 2007) incorrectly identified the organization to which health economist Ruth Levine, PhD '90, belongs. It is the Center for Global Development. We regret the error.

Tooting Our Own Horn Department

Epidemiology Monitor [June 2007] ranked Johns Hopkins Public Health magazine as the number one school of public health magazine.

"The Genetic Journey" [Spring 2007] was given an Award of Excellence from the Association of Medical Illustrators. The illustration also won semifinalist honors in Informational Graphics from the 2007 International Science & Engineering Visualization Challenge sponsored by the National Science Foundation and the journal Science.

The Council for Advancement and Support of Education awarded the magazine a national bronze medal for Special Interest Magazines.
