Longevity News and Review provides readers with the latest information in breakthroughs pertaining to the extension of the healthy human lifespan. These news summaries are compiled by the American Academy of Anti-Aging Medicine (A4M; www.worldhealth.net), a non-profit medical society composed of 22,000 physician and scientist members from 105 nations, united in a mission to advance biomedical technologies to detect, prevent and treat aging related disease and to promote research into methods to retard and optimise the human aging process. Dr Robert Goldman, M.D., Ph.D., D.O., FAASP, A4M Chairman, and Dr Ronald Klatz, M.D., D.O., A4M President, physician co-founders of the anti-aging medical movement, distil these headlines and provide their commentary.
Friendships Prompt Positive Brain Function
In that kinship, friendship alliances and perceptions of others’ beliefs guide social interactions and are central to cohesive group behaviour, Fenna M. Krienen, from Harvard University, and colleagues studied how the medial prefrontal cortex region of the brain processes social information. The researchers found that people’s brains are more responsive to friends than to strangers, even if the stranger has more in common, thereby suggesting that social alliances outweigh shared interests. The team’s findings affirm the hypothesis that certain regions of the brain process the social relevance of the person (closeness) to oneself and contribute to the assessment akin to signals that govern behavioural approach responses.
Dr Klatz observes: In revealing that a specific region of the brain responds positively to social alliances, this team enlightens the complex behavioural interactions between individuals.
Personality Contributes to Exercise Capacity
Scientists now recognize that many animals exhibit personality, behavioural displays known as “consistent individual differences.” Peter Biro, from the University of New South Wales and colleagues reviewed a wide range of recent research and posit that there is now enough evidence to suggest a link between an individual’s personality and the rate of its metabolism – the chemical process that converts food into the energy that fuels the body. The researchers investigated why individuals differ in their propensity for activity and in their personality, and why these two factors may be related. They found that behaviours often relate to the rates at which an individual acquires and expends energy through feeding or physical activity.
Remarks Dr Goldman: Australian researchers make the intriguing discovery that an individual’s personality and their rate of metabolism are fundamentally linked. If confirmed, this may become an important insight of value in customising an individual’s fitness regimen.
Multivitamins May Ward off Heart Attack Risk
Multivitamin and mineral supplements have been shown by previous studies to significantly lower the risk of myocardial infarction, and that the combined use of multivitamins and supplements of vitamin A, C, or E may yield a 25-percent lower risk of coronary heart disease mortality. Susanne Rautiainen, from Karolinska Institutet in Sweden, and colleagues assessed the relationship between multivitamin use and myocardial infarction in a population of over 30,000 Swedish women ages 49 to 83 years. Among those women with no history of cardiovascular disease, the daily use of multivitamins alone (as compared with no use of supplements at all) was associated with a 27-percent lower risk of myocardial infarction. Additionally, women using multivitamins in combination with other supplements were at a 30-percent lower risk of myocardial infarction. The team concludes that: “The use of multivitamins was inversely associated with [myocardial infarction], especially long-term use among women with no [cardiovascular disease].”
Comments Dr Klatz: Swedish study reveals that women who take a daily multivitamin may be at a reduced risk for heart attack. This finding underscores the life-saving importance of essential nutrients in the diet.
Anti-aging medicine is the fastest-growing medical specialty throughout the world and is founded on the application of advanced scientific and medical technologies for the early detection, prevention, treatment and reversal of age-related dysfunction, disorders and diseases. It is a healthcare model promoting innovative science and research to prolong the healthy lifespan in humans. As such, anti-aging medicine is based on solid scientific principles of responsible medical care that are consistent with those applied in other preventive health specialties. The goal of anti-aging medicine is not to merely prolong the total years of an individual’s life, but to ensure that those years are enjoyed in a productive and vital fashion.
