This is another post derived from a presentation given at the 2011 Annual Summer Meeting of the Wilderness Medical Society. Tracy Cushing, MD, of the University of Colorado School of Medicine gave an excellent presentation on submersion injury—i.e., the dangers of becoming submerged under water. What follows is some of what we learned.
Historically there have been many terms and definitions, such as “drowning,” “near-drowning,” “dry drowning,” and others. Current experts favor the term “submersion injury” as any adverse effect from submersion in water. This commonly causes difficulty breathing, for many reasons. “Immersion syndrome” refers to the situation where there is a lethal heart rhythm during or after a cold-water exposure, usually attributed to stimulation of the vagus nerve, which slows the heart rate. “Shallow water blackout” refers to a person becoming unconscious after hyperventilating prior to attempting a lengthy period of breath-holding underwater.
Middle-aged women who drink alcohol moderately yet regularly throughout the week may age more healthfully, according to data from the Nurses’ Health Study.
After adjusting for variables such as smoking, women who drank light or moderate amounts of alcohol had a modestly increased chance of successful ageing compared to nondrinkers. For example, compared to nondrinkers, women who drank 5 to 15 g of alcohol per day (between one-third and one drink per day) at middle age had about a 20% higher chance of successful ageing, defined as being free of 11 major chronic diseases and having no major cognitive, physical or mental health limitations at age 70.
Independent of total alcohol intake, women who drank alcohol regularly had a better chance of successful ageing than occasional drinkers. Thus, compared to nondrinkers, women who drank five to seven days a week had nearly a 50% greater chance of successful ageing whereas women who drank only one or two days a week had a similar likelihood of successful ageing.

A gripping piece by the Transport Accident Commission (TAC) in Victoria about drinking and driving and the use of illicit drugs. Words cannot depict this powerful and graphic piece. Take a look:
“On December 10, 1989 the first TAC commercial went to air. That year the road toll was 776. Twenty years on it has fallen to 303. There is still a long way to go.”
We would love to hear from you. Did this video move you in any way? Did it increase your awareness? We would love for you to share your insightful thoughts. As always, thank you for your time.

A new study published in the American Journal of Clinical Nutrition is reporting an association with eating meat and weight gain. This is a fairly robust epidemiological study, but at the same time is a good example of how such information is poorly reported in the media, leading to public confusion.
The data is taken from the European Prospective Investigation into Cancer and Nutrition–Physical Activity, Nutrition, Alcohol, Cessation of Smoking, Eating Out of Home and Obesity (EPIC-PANACEA) project. This is a long-term epidemiological study involving hundreds of thousands of individuals, and is therefore a great source of data. We are likely to see many publications from from it. This one looked at the association of meat eating –- poultry, red meat, and processed meat -– with total weight. Read more »
What is it about our culture that encourages newer and riskier ways to challenge our health? Public health folks have become very concerned about the latest challenge – alcoholic energy drinks. These are prepackaged beverage with alcohol and caffeine, as well as other stimulants, that look like other energy drinks but carry a much more powerful, and dangerous, punch!
There were 500 new energy drink products introduced worldwide in 2006 with average sales topping $3.2 billion. These products are targeting youth by creating brand confusion with nonalcoholic versions; providing a cheap alternative to mixing energy drinks with alcohol; and using youth-friendly grassroots and viral marketing. The names of these products say it all – Rockstar, Sparks, and Tilt. Read more »
