BPA Might Cause Asthma Risk Increase in Children BPA Might Cause Asthma Risk Increase in Children

March 03, 2013- BPA or bisphenol A, once again has been tied to increasing the risk of a health problem in humans. Now, the increased risk is for children developing asthma.

New research shows that an excess exposure to the chemical, which interferes with certain hormones being produced in the body, has been linked previously to increased risks of obesity in children and more of a chance of diabetes, kidney disease and heart disease later in life could increase the risk of young children developing asthma. The chemical has been banned from the lining of infant baby formula cans and baby bottles. However, there are other hard plastics and metal can coatings that still contain the chemical.

This new research, just like a dozen previous, measured the levels of BPA in urine and then compared those with rates for a particular illness such as asthma. The study found a 40% increase in the risk of asthma in children from the inner city. The highest levels of BPA were in children 3, 5 and 7 years old. About 25% of the children had asthma.

The heightened risk was only modest but still consistent with other studies done prior linking BPA levels that were high in women who were pregnant with the risk of their baby developing asthma at a later date. The new study did not find that exposure to BPA during prenatal affected the child’s risk of developing asthma later, which was an unexpected finding by researchers.

The study did not prove that being exposed to BPA caused the increased risk in developing asthma. The study included certain factors that are known to affect the risk of developing cancer like being exposed to cigarette smoke, ethnicity and the mother having asthma history, which could also play a part in the risk of developing asthma.

Single Carbonated Sugary Drink Could Increase Diabetes Risk Single Carbonated Sugary Drink Could Increase Diabetes Risk

February 28, 2013- Drinking just one can of carbonated sugary drink per day could raise the risk of later developing Type 2 diabetes, that could be life threatening. Scientists were able to find that calories that are sugar-based, such as the ones found in carbonated sugary drinks, are more apt to be a cause of the condition, than the calories in the same amount that are from another source.

For each additional 150 calories from sugar per day per person, the prevalence of diabetes increased in the population by 1%. In contrast, 150 calories additional daily of any type only caused a 0.1% increase in the rate of diabetes in the population, said the researchers from the University of California San Francisco, University of California Berkley and Stanford University.

For the first time scientists have questioned a theory that eating an excess of any food is what causes a person to become obese and that the obesity that results, is what then causes the diabetes.

Data was examined by researchers on diabetes rates and sugar availability from over 175 countries, over the last decade. After researchers had accounted for obesity along with a myriad of other factors, it was found that increased sugar within the food supply of a population was linked to a higher prevalence of diabetes rates, independent from the obesity rates.

This is the first population based large scale evidence for the theory that not all forms of calories are equal from a standpoint of diabetes risk.

Researchers not only correlated the risk of diabetes according to sugar availability but also they found the longer a certain population had been exposed to an excess of sugar, the higher the diabetes rate became.

In addition, the rates of diabetes fell over time as the availability of sugar dropped. This was independent of any changes in the consumption of other forms of calories, physical activity or of obesity rates.

Heart Troubles Lowered by Mediterranean Diet Heart Troubles Lowered by Mediterranean Diet

February 25, 2013 - A Mediterranean diet that is rich in nuts and olive oil lowered the risk of cardiovascular events among people who were at an increased risk for those events, reported researchers.

In Spain, in a trial that was randomized in people who were at high risk, those eating a Mediterranean diet that was supplemented with additional mixed nuts or olive oil saw a lowering in the number of cardiovascular events by close to 30% in comparison to a control group that ate a low-fat diet, said researchers from Barcelona.

Members of the group that performed the study said that its results support using a Mediterranean diet for the primary prevention of developing heart disease. However, they cautioned that the participants in their study lived in a country in the Mediterranean and had already been at high risk for those types of events, therefore it is not fully clear how the results would be for other people.

Nevertheless, the data from the trial and the monitoring board ruled that the benefits were sufficiently clear to stop the study.

A traditional Mediterranean diet noted researchers is characterized by large amounts of olive oil, nuts, fruits, vegetables, cereals and legumes. It also includes some poultry and fish and a limited amount of red meat, dairy products, sweets and processed meats. The diet also includes, during meals, a moderate amount of wine.

In the study, researchers randomly assigned over 7,440 people between 55 and 80 years of age one of three different diets – a Mediterranean diet that contained an additional supplement of mixed nuts, a Mediterranean diet that included extra olive oil or a control group diet low in fat.

After an average follow up of 4 years and 9 months, 288 of the participants had a primary endpoint event, which is characterized as a heart attack, stroke or cardiovascular death.

Ninety-six of them were in the high olive oil group, 83 in the high nut group and 109 in the control group. In a multivariable analysis that was used, the diet high in olive oil lowered the risk of a cardiovascular event by 28% compared to the control group. The high nut diet lowered the risk similar to that of the diet high in olive oil.

New Breast Cancer Drug Approved by FDA New Breast Cancer Drug Approved by FDA

February 23, 2013 - On Friday, the U.S. Food and Drug Administration approved a new drug that uses a combination of a breast cancer medication, Herceptin, that is widely used, with a toxin that is highly powerful, to kill cancer cells more effectively while also potentially lowering the number of side effects.

The new drug is named Kadcyla, but in its development was referred to as T-DM1. It extended the average survival rate of women who had advanced breast cancer close to six months in one clinical trial.

The drug was developed by Genentech and the company said it would have a cost of approximately $9,800 per month or about $94,000 for a full treatment. That price is about twice the cost of Herceptin, which Genentech also manufactures, but the price is similar to some of the other newer drugs to fight cancer.

The company announced that Kadcyla would be available in days. The drug is one of the first examples of a new class of cancer drugs that have linked toxins to proteins referred to as monoclonal antibodies. Those antibodies attach to tumors and then inject the toxic payload into the tumor. Since the toxin is inactive until it latches onto the tumor, cells that are healthy get spared and some of the side effects do not take place.

These types of drugs have become an important for those who develop cancer drugs. Close to two dozen of these drugs are currently being tested in clinical trials. Adcertis, another of the antibody drug conjugates, which Seattle Genetics developed, received approval in 2011 for the treatment of two rare forms of lymphoma.

The clinical trial that led to Kadcyla to be approved involved more than 990 patients who suffered from breast cancer that was metastatic and worsening despite being treated with Herceptin and a chemotherapy drug. Patients received either Kadcyla infusions or two other pills, which were commonly used for patients suffering from this form of cancer.

Those receiving the Kadcyla lived an average of nearly 31 months, compared to 25 months for those receiving the pills.

Study: Ozone Levels and Air Pollution Could Cause Cardiac Arrest Study: Ozone Levels and Air Pollution Could Cause Cardiac Arrest

February 21, 2013 - A study of large proportions done in Texas shows that when the levels of air pollution are high, especially with particles that are soot-like, then cardiac arrests are more common.

Medical conditions that involve the lungs and heart disease have been attributed for a long time to the quality of the air, but this new study suggests that the levels of the ozone could also play a part in the risk a person has for experiencing cardiac arrest.

Cardiac arrest takes place when there is a sudden stop in the heart beating and it therefore cannot pump blood to other parts of the body. It is caused by the heart having electrical problems, sudden trauma or conditions that was pre-existing. Over 300,000 Americans suffer from cardiac arrest annually and fewer than 10% survive.

The recent study compared cardiac arrest data that took place outside hospitals in the city of Houston with records of air quality between 2004 and 2011. Researchers were able to find that out of over 11,000 total cardiac arrests that had occurred without a specific cause such as trauma, an increase was detected when the levels of the ozone were recorded as being abnormally high.

The recently published study found that an increase in the risk of having cardiac arrest was 4.4% for every 20 parts p/bn that the ozone was listed as above average within the previous 180 minutes.

Researchers also were able to find that a risk of cardiac arrest was similar when pollution of small particles was recorded. Cardiac arrests were higher by 4.6% for every 6 micrograms increase of particles per cubic meter within the previous 48 hours.

There is more that needs to be studied, said researchers, but there is evidence that suggests the particulates in the air are causing inflammation when entering through the human respiratory system and cause stress on the heart.

Texas Mom: Four Babies, Two Sets of Twins Texas Mom: Four Babies, Two Sets of Twins

February 19, 2013 - A couple in Texas, trying to give a sister to their little son, instead gave him four brothers. The mother delivered quadruplets – two sets of twin boys who were identical and conceived at the same time.

The happy mom Tressa Montalvo gave birth to Dylan, Cash, Blaine and Ace on February 14 said the hospital in Houston, Texas. Dylan and Cash shared a placenta, while Blaine and Ace shared another one.

Montalvo said they decided to stick to an easy ABCD theme for naming the boys. She said they tried for just one and were blessed to be given four. At first, the couple thought twins were in order, then their doctor found a third heartbeat and a specialist found a fourth.

Only about 2% of all pregnancies result in identical twins, which is when an egg splits and forms two embryos. However, the odds of having two sets of identical twins in the same pregnancy are very slim. That chance is about 1 in 10,000, said medical officials.

The couple said they did not use fertility drugs and the pregnancy was planned. The boys were born at 31 weeks by C-section and they weigh between 3 pounds and 4 pounds.

While the delivery of two sets of identical twins is rare, it is not all that unheard of. In April of 2011, Josh and Miranda Crawford had identical twin boys and identical twin girls after Miranda underwent in-vitro fertilization. Christina Tetrick, in 2002, had two sets of twin boys who were identical.

Even though the Montalvo’s home is now much more crowded than before, the parents of five still want a girl.
