, People who are exposed to trichlorethylene (TCE) were six times more likely to develop Parkinson’s. The use of TCE in food and pharmaceutical industry has actually been banned since the 1970s, but this substance is still widely used in metal cleaning agents.
The team of researchers from the U.S., Canada, Germany and Argentina, led by Dr. Samuel Goldman of The Parkinson’s Institute in Sunnyvale, California identified six specific solvents are allegedly associated with Parkinson’s, two of which are TCE and PERC.
Researchers then analyzed 99 pairs of male twins, with one person stricken with Parkinson’s and her partner did not. This analysis of data obtained from military records of the National Academy of Sciences or the National Research Council World War II Veteran Twins Registry, founded in 1960.
Goldman and his team interviewed the twins about their work in detail with a questionnaire to measure the likelihood exposed to solvents have been determined.
Researchers have finally found exposure to TCE, PERC, and other chemicals which are known as carbon tetrachloride in a low level associated with an increased risk of disease neurodegenerative or damage the nerve.
“Our findings indicate a pause of up to 40 years between exposure to TCE and began thus potentially slowing the emergence of Parkinson’s disease before clinical symptoms appear,” said Dr.. Goldman was quoted as saying of dailymail, Tuesday (15/11/2011).
Disease Parkinson’s is caused by the loss of nerve cells in the brain and can cause tremor (shaking), slow motion, and cause disruption to talk.
TCE was used in adhesives, carpet cleaners, paint solution, and dry-cleaning solution. Until now, this substance is still used as a cleaning agent for metals. It is estimated that about 30 percent of U.S. drinking water supplies contaminated by these chemicals.
“This is the first study to show that the solvent TCE may be associated with an increased risk of Parkinson’s. It is important to highlight that the use of these solvents have been discontinued for safety reasons more than 30 years ago and protection in the workplace where chemicals are used has increased in recent years, “said Dr. Michelle Gardner, manager of research development at the Parkinson’s UK.

, People with uric acid (gout) should ensure that uric acid levels were in normal range. While not experiencing the painful symptoms of rheumatic disorders despite high levels of uric acid could be at risk of developing diabetes.
“Many people who have uric acid levels are not controlled and has been used to not worry about it. Especially if it does not cause symptoms, “says Eric Matteson, MD, MPH, chief of Rheumatology at the Mayo Clinic, Rochester, Minn., as reported by WebMD , Monday (14/11/2011).
But The new study results show that high levels of uric acid in the blood associated with increased risk of diabetes almost 20 percent and increased risk of conditions that lead to the development of disease kidney more than 40 percent.
Acid veins are chemicals that can form in the blood and can increase to levels higher than normal and cause gout.
While gout is a medical condition that is usually characterized by recurrent attacks of acute inflammatory arthritis symptoms, including redness, pain, hot joints, and swollen.
Metatarsal phalangeal joint at the base of the big toe is the most frequently affected with gout, which is at about 50 percent of cases. However, it can also appear in the form of tophi, kidney stones, or urate nephropathy. This is caused by elevated levels of uric acid in the blood that has been crystallized and stored in the joints, tendons and surrounding tissues.
The researchers reviewed the records of about 2,000 people with gout in a Veterans Administration database. At the beginning of the study all of the study participants without diabetes or disease kidneys.
Eswar Krishnan, MD, assistant professor of Rheumatology at Stanford University, has presented his research results at the annual meeting of the American College of Rheumatology.
Over a period of three years, 9 percent of men with gout have uric acid levels are not controlled under conditions that lead to the development of diabetes. Compared with 6 percent of those with uric acid levels are controlled.
After accounting for other risk factors for diabetes, was found associated with diabetes risk 19 percent higher in those with uric acid levels are not controlled. Uric acid levels in the blood that are higher than the number 7 is considered uncontrolled.
The second study conducted by the same researchers using the same database. The results of these studies indicate that, over 3 years with periods of gout in men who had higher levels of uric acid that is not controlled had 40 percent higher risk for disease kidney compared with men with uric acid levels under control.
study did not prove that, uric acid levels are not controlled cause health problems but showed elevated levels of relationships with health problems.
“Gout is a disease which is not handled. Now we find that high uric acid levels, is associated with higher risk for heart disease, metabolic syndrome, diabetes, and even death from cardiovascular disease, “said Matteson.
” Therefore this, it will be advisable to perform a variety of efforts to control uric acid levels, including through diet or drugs. It is most important, maintaining a healthy weight. Because obesity is a major risk factor for all these conditions, “said Matteson .

, Eating fiber and whole grains has long been known to help protect themselves from disease cardiovascular. Not unexpectedly, food, fiber and whole grains can also reduce the risk of colon cancer.
According to a new study, eating more cereal and whole grains can reduce the risk of colorectal cancer (colon). The researchers from Imperial College London found that every increase of 10 grams of fiber intake in one day, there will be a reduced risk of colon cancer by 10 percent.
This study is somewhat different from the analysis in 25 previous studies that found that fiber fruits and vegetables does not reduce risk of colon cancer. Latest review the results of this study have been published in the British Medical Journal .
/> Grains include foods such as whole wheat bread, brown rice, cereal, oatmeal and porridge. From the analysis the researchers found that, there is a linear relationship between dietary fiber and colon cancer.
“intake of fiber in an amount sufficient to have some benefits,” says Dagfinn Aune, one of the researchers from the department of epidemiology and Biostatistics at Imperial College London, as reported from BBCNewsHealth, Sunday (11/13/2011).
Adding three servings (90 g per day) of grains in the daily diet can lower colon cancer risk by 20 percent.
“A previous study has shown a reduced risk of colon cancer because of high intake of fruits and vegetables. It shows that, other compounds from the fiber in fruits and vegetables may explain the mechanism. The health benefits of increasing fiber intake of whole grains and are not limited to benefits for colon cancer only. It also tends to reduce the risk of disease heart (cardiovascular), type 2 diabetes, and mortality due to obesity, “the researchers said.
“We recommend that the daily balanced diet of high fiber foods such as grains, cereals fruit and vegetables to reduce the risk of colon cancer,” said Mark Flannagan, chief executive of Beating Bowel Cancer.
But according to Yinka Ebo of Cancer Research UK, eating lots of fiber is just one of many things that can be done to reduce the risk of disease .
“It must also be done in conjunction with maintaining a healthy weight, be physically active, reducing alcohol, red meat, and not smoking. wheat products should be made more attractive to buyers,” says Prof. Anne Tjonneland of Danish Cancer Society.
Results were considered to be very useful for a healthy diet recommendations daily. However, it still needs to be done several studies to clarify the quantity and type of fiber that must be consumed to reduce the risk of colon cancer.

, Patients with organ damage will be faced with difficult choices. Recent studies show that organ transplant recipients doubled risk of cancer than the general population. And the risk increases to 32 different cancer types.
However, experts say that the benefits of transplantation far outweigh those risks.
“People need to understand that transplantation is one of the biggest success stories in medicine. This is a very effective treatment for patients with diseases organ damage, “explains the study’s lead author, Dr. Eric Engels, senior researcher of the infection and the epidemiology of the Division of Epidemiology Cancer and Genetics at the U.S. National Cancer Institute in Rockville.
Engels and his team examined data of almost 176,000 solid organ transplants performed in 1987 to 2008 in the U.S.. The researchers found that overall cancer incidence rate 2.1 times higher than expected in non-transplant population.
Risk disease Non-Hodgkin’s lymphoma increased by more than seven times. Levels of lung cancer and liver also increased significantly, but Engels says this may be because the cancer has gone before.
For example, a treatment for some types of liver cancer is by way of a liver transplant, and it may be due some cancer cells survive the transplantation process.
The risk of lung cancer in transplant recipients highest lung and liver cancer risk seems only to increase in liver transplant recipients.
According to this study, the incidence of kidney cancer increased almost five fold in all transplant recipients. This is possible because disease of the underlying patient needs a new kidney and the possible immunosuppressive role in all transplant patients.
“Our research confirms that this population has a unique pattern of cancer risk. transplant recipients should be examined carefully and continuously monitored, “Engels added, as quoted from HealthDay on Wednesday (02/11/2011).
In 2010, nearly 30,000 solid organ transplants performed in the United States. Kidney transplants account for more than half of that number, followed by liver, heart and lungs.
After transplantation, recipients must have an immune system suppressing drugs (immunosuppressants) are strong to prevent rejection of new organs.
“Suppressing the immune system increases the risk of cancer. And if a patient has cancer, it takes a strong immune system to fight cancer,” says Dr. Darla Granger, director of the pancreas transplant program at St. John Hospital and Medical Center in Detroit.
Another problem associated with immunosuppressive drugs is a cancer associated with the virus. For example, disease non-Hodgkin and Hodgkin lymphoma associated with Epstein-Barr virus, while some types of cervical cancer are caused by human papillomavirus virus (HPV), and some liver cancers are caused by viral hepatitis B or C.
“We know that a particular tumor will develop after transplantation. certain tumors are also associated with known viruses. So when we gave immunosuppressive drugs, we reduce the body’s ability to fight viruses,” explains Dr. Lewis Teperman, head of the surgical transplantation at NYU Langone Medical Center in New York City.
Not all cancers are related to the immunosuppressant, but in cases such as liver cancer and lung cancer, there is little chance that the cancer had appeared in the body prior to transplantation.
“It’s hard to sort out the causes for certain cancers, but some of them clearly related to the immunosuppressant,” Granger said.
“This study is raises some very good points. This suggests that screening for viruses to do, and that we should always try to reduce the use of immunosuppressants. It also creates a tendency to screen tumors in transplant recipients, “Teperman said.
“This is an important finding. But I think it overestimated the actual risk of cancer may be lower than those seen in this paper,” he added.
For someone who has been undergoing or awaiting transplant , Granger suggested that lowering risk factors, ie do not smoke, follow good health practices, wear sunscreen, and if it is transplanted, live skrinin screenings recommended by doctors.

Buenos Aires, Argentina, Although a lot of stroke associated with modern lifestyles such as diet high in fat and calories, but in fact people who live in poor countries have a higher stroke risk than people in rich countries.
The study has been published in the latest issue of Stroke Journal, showed that people living in poor countries and in countries that spend less money for health care are more likely to suffer a fatal stroke, compared with rich countries .
The new findings also showed that more prevention efforts are needed, especially in developing countries.
“Not only the level ekononi important country, but also what proportion of gross domestic product (GDP) or gross domestic product (GDP) that they spend on health. It is important to develop health care strategies to prevent disease strokes and other blood vessels, “explained Dr. Luciano Sposato, director of the department neurology at the Vascular Research Institute in INECO Foundation, Buenos Aires, Argentina, as reported by Health24 , Monday (31/10/2011).
In this study, researchers studied 30 studies from 22 countries and identify the relationship between stroke and the three economic indicators are widely used, namely gross domestic product (GDP), health spending per person and the unemployment rate.
As a result, although the unemployment rate found no effect on risk stroke, the study found a lower GDP is associated with stroke risk 32 percent higher, jumped 43 percent in the second 30-day mortality after stroke and hemorrhagic stroke (bleeding in or near the brain), and 47 percent increase in strokes in young people.
Meanwhile, researchers found that worked with little expenditure on health care costs associated with stroke risk 26 percent higher, rising 45 percent in the 30-day mortality after stroke, and jumped 32 percent in hemorrhagic stroke. Stroke rates among young people has also increased 36 percent.
“It is important to further discuss health priorities for each country. This will provide the necessary background to help countries make the changes in resources and money allocated, “explains Dr. Gustavo Saposnik, director of stroke research at St. Michael’s Hospital, University of Toronto.
