H1N1 vaccine to arrive on Tuesday
The vaccine against the H1N1 virus is scheduled to arrive in 21 states and the cities of Washington D.C., New York, Chicago, and Los Angeles by this Tuesday. Around 600,000 doses will arrive at these places.
Additionally, 300,000 doses of the antiviral Tamiflu are expected to arrive at various locations over the coming week. The initial doses of the vaccine will be in the form of a nasal spray. Health officials will be given the first available doses of the H1N1 vaccine.
Health officials do not recommend the vaccine for pregnant women, those with other health issues, and children below the age of 2.
Vitamin D reduces risk of falling
According to research published in the British Medical Journal, a dose of 700–1000 international units (IU) of vitamin D can reduce the risk of falling in those over 65 years of age. IU is the international unit for measuring vitamins.
The research has also shown that doses below 700 IU are not effective in preventing falls.
Yearly, one in three persons over the age of 65 experiences a fall and 6 percent of those falls can result in fractures.
Thus, vitamin D, which increases the strength of the elderly and also improves their balance, could help prevent such falls.
Obesity shown to cause cancer
Researchers have shown that obesity could be a leading cause of cancer in women. Obesity is responsible for 8 percent of all the cancers in Europe.
Some studies have shown that in the United States, obesity was responsible for almost 20 percent of all cancers.
Scientists believe that with more people quitting smoking, obesity may soon become the leading cause of cancer within the next decade or so.
Of all the cancers linked to being overweight, colorectal cancer, breast cancer, and endometrial cancer accounted for 65 percent.
Although scientists are unsure of why obesity can cause cancer, they believe that it has to do with the fact that more hormones are released with obesity. Hormones like estrogen, secreted in excess, could help tumors grow.

Anti-smoking drug may not cause suicide
In July, the United States ordered black box warnings on anti-smoking drugs like Chantix and Zyban following reports of depression and suicidal thoughts following the use of these drugs.
However, recent research published in the British Medical Journal shows that there is no strong evidence indicating that Chantix is linked to suicide.
The findings were based off of data obtained from 80,660 people who used such drugs from Sept. 2006 to May 2008. Researchers did not find any reports of serious mental health problems in these users while they were using these drugs or even three months after they stopped using them.
