Indonesia confirms two more bird flu deaths

Jakarta (VNA) - The Indonesian Health Ministry on August 13 confirmed the deaths of a woman and her daughter in Bali as a results of bird flu, bringing the country's total death toll from the disease to 83.

These were the first human deaths from bird flu on the resort island, where the H5N1 virus was identified more than a year ago.

The 29-year-old woman died on August 12 and her five-year-old daughter on August 3, Bayu Krisnamurti, head of the national commission for bird flu, said.

Laboratory tests provided by the Eikman Institute and the Health Ministry confirmed the presence of H5N1 in both cases, Bayu told reporters.

This NYT article by the prolific health and fitness writer, Gina Kolata, is one of several in the national newspapers this week which reports on a study in the New England Journal of Medicine. 

 

The  study found that if you have a friend, spouse or relative who becomes obese, you are much more likely to become obese, or in the words of the study itself:  “Network phenomena appear to be relevant to the biologicand behavioral trait of obesity, and obesity appears to spreadthrough social ties.”

 

Some in the media have expanded this language “spread through social ties” interestingly saying that obesity is “contagious.” 

 

Clearly what is at work here is the reconfirmation of a very old phenomenon—we are influenced in many direct and subtle ways by the habits, actions and characteristics of those close to us—note that a neighbor’s obesity did not show causality because we aren’t necessarily socially close to our neighbors..

 

Americans do pay attention to the way their close friends act and live.  We tend to wear the same clothes, go to the same stores, take the same vacations, see the same movies and listen to the same music—to some extent.  For example, if a close friend or sibling returns from a European vacation, we are likely to follow.   And, if close friends or siblings become fat, well, gradually our norms for what is acceptable weight-wise may loosen and we are probably less resistant to gaining weight.

 

I think that all that is going on here is re-affirmation of  age old peer group pressure/influence as it pertains to obesity.  The study results are correct and meaningful in this respect.  However, the idea that obesity is somehow “contagious” is somewhat off the mark and summarizes the problem in an unhelpful way—because Americans are always searching for that reason why obesity is not their fault.

 

So, although your close friends may have an influence on your obesity norms, you certainly can’t blame them for your own obesity, anymore than you can blame them for your wardrobe, the kind of car you drive or your last vacation.

 

The first step in fighting obesity is take responsibility for your own BMI.

 

Baxter says trial on new flu shot promising

Baxter International Inc., working to modernize the production of influenza vaccines, this morning said its seasonal flu product is showing "strong antibody responses and good tolerability" in an early stage clinical trial in humans.

Although Baxter is still several years from winning approval of the product, the study shows Baxter's reformulated seasonal flu vaccine is tolerable. In late 2004, Baxter had to suspend final-stage human sudy of its seasonal flu vaccine because it was causing fevers in some patients.

The Deerfield-based medical product giant is trying to develop a flu vaccine produced with cell tissues, which is a method that would allow manufacturers to quickly brew vaccine by the vat and likely eliminate shortages like the one that rattle U.S. consumers and health-care providers from time to time.
The cell-based approach is a sharp contrast to the tedious, 1940s method still used today that involves hand-processing millions of chicken eggs in labs. For each dosers shine a light through the shell of an egg to find the fluid surrounding an embryo, inject a strain of the flu virus and let it incubate for several months.

The current method is a long months-long process fraught with risk, while cell-based vaccines are more consistent and could be produced in as little as nine to 12 weeks.

In the latest clinical trial, Baxter said more than 900 patients were studied. Baxter said the preliminary data show its cell-based seasonal influenza vaccine's "tolerability profile" to be similar to egg-based seasonal flu vaccines on the market. There were, however, some side effects that included headaches and some injection site reactions, Baxter said.

Baxter is building momentum for its vaccines business. The company is also in the final stages of testing for a vaccine against strains of the Avian influenza, also known as the bird flu and is working with governments around the world interested in stockpiling the product in the event of a pandemic outbreak.

This AP article via the Washington Post is typical of many articles that have been reporting on a recent study of 9,000 observations of middle-aged men and women which was published Monday online in the journal Circulation.

The study has reported that “People who drank one or more diet sodas each day developed the same risks for heart disease as those who downed sugary regular soda.”

Needless to say this is somewhat of a surprising result since it’s definitely counter intuitive that the diet colas would have the same impact as fully sweetened sodas given the massive calories contained in the latter. Not surprisingly, a representative from the American Beverage Association opined:  "How can something with zero calories that's 99 percent water with a little flavoring in it ... cause weight gain?"

Still, the study found those who “drank one or more sodas a day diet or regular had an increased risk of metabolic syndrome, compared to those who drank sodas infrequently. Metabolic syndrome is a cluster of symptoms that increase the risk for heart disease including large waistlines and higher levels of blood pressure, blood sugar, cholesterol and blood fats called triglycerides.”

Some of the theories being put forth are as follows:

1.      Adverse selection problems.  One contingent of diet soda drinkers are already overweight and drink diet sodas in an attempt to keep from gaining more.  Their link to heart disease is due to their overweight status, not the fact that they drink diet sodas.

2.      Diet sodas condition the palette to sweetness and users over consume non diet sweetened products elsewhere in their dietary intake, increasing weight gain and heart disease.

3.      There is something about diet drinks that we don’t understand.

Still, according to the article, the American Heart Association still condones the use of diet sodas as part of a program to control weight.

In our opinion, the most useful function of diet drinks is to help wean yourself off of regular fully sweetened soft drinks.  If you are still drinking fully sweetened soft drinks you are definitely not serious about losing weight.  However, once you have successfully accomplished this goal, the next step should be to replace diet drinks with, yes you guessed it, water.  Over time, you can adjust your palette so that ice water or carbonated ice water is just as refreshing as diet sodas.  And when you drink water you don’t have to be concerned with the caffeine content, availability, or the risk that this recent study  may in fact be correct.  Dribbling a little orange juice into soda water over ice can also be a refreshing low calorie and healthful drink.
