Research found Kidney Cancer Caused By Heavy Smoking



The research report that people who like smoking will have a high chance to get risk of advanced kidney cancer. 

In a new study, a team from Duke University Medical Center reviewed the cases of 845 patients who had had surgery for kidney cancer -- or renal cell carcinoma -- between 2000 and 2009. They found that current and former smokers were 1.5 to 1.6 times more likely to have advanced cancer rather than nonsmokers.

For smoker that has been smoking for along period of time was associated with advanced renal cell carcinoma. The investigator had found that about 9 percent reduced the risk disease only for every 10 years
The American Urological Association’s annual meeting, in Washington. D.C get special press conference from this findings. Beside that, the rates of bladder cancer did not fall along with lower rates of smoking in the United States. Another study showed that the researchers also examined a national database and found that lung cancer rates decreased per capita consumption of cigarettes between 1973 and 2007, in contrast the same type of consistent decline was not seen in bladder cancer rates.

The researchers at the State University of New York Upstate Medical University in Syracuse said in a news release from the American Urological Association, rising in bladder cancer in a few decades have been offset by other contributing instead of decreasing in bladder cancer duo to smoking.

Dr. Toby Kohler said in the news release that these two studies actually bring a new insight which has two crucial urologic cancers. Moreover, kidney tumors can happened at this day and easily detected by people, it is because the more people smoke, the more aggressive cancer is.  Cessation of smoking seems to lower the risk," Kohler said.

"For bladder cancer on the other hand, the decrease in smoking rates has not impacted the incidence to the same degree that it has for lung cancer, suggesting that there may be other factors which are becoming more important for the development of the disease," he added.

The good way of avoiding risk of kidney cancer is “DON’T SMOKE”.  Try to stay away from cigarette start from now if you don’t want get cancer soon. These studies are being presented at a medical meeting, the data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.

Research Showed Stroke Might Happen while Sleeping



Recent study proved that 1 in 7 get strokes during sleep, About 14 percent of strokes happen while people are sleeping, lowering the chance that they'll be able to get to the hospital in time for a potentially brain-saving treatment, a new study suggests. 

As we know that the only treatment of ischemic stroke should be given a few hour by the time symptoms begin. Ischemic stroke which is caused by blocked blood flow in the brain, usually because of a clot. Mostly, people who wake up with stroke symptoms often can't receive the treatment since we can't determine when the symptoms started. Dr. Jason Mackey, of the University of Cincinnati and a study co-author, said in a news release from the American Academy of Neurology. “some study is trying to develop what benefit will be got in order to make better methods so that study will be conducted to identify it include symptoms started during night

In the study, published in the May 10 issue of Neurology, researchers examined the medical records about 1,854 adults who suffered from ischemic strokes in a one-year period and were treated at emergency rooms in the Cincinnati area. In 14 percent of the cases, people woke up with symptoms of a stroke. The study authors pointed out that Nationwide had accounted for 58,000 people who visit emergency rooms with stroke systems every yearOf 273 people who had so-called "wake-up strokes," at least 98 would have been eligible for treatment with a blood clot-busting drug called tPA if doctors had known when the stroke had begun, the study reported.

"If a stroke started more than a few hours ago, tPA is not indicated because it is so dangeraous which can cause bleeding and more will extend and enlarge the stroke," explained Dr. Byron K. Lee, associate professor of medicine and director of the Electrophysiology Laboratories and Clinics at the University of California, San Francisco. "In wake-up strokes, it's nearly impossible to know when the symptoms started [so] tPA is not an option and, therefore, the neurologic deficits have a higher chance of becoming permanent."
According to the National Stroke Association, there have some possible symptoms of a stroke occur:
  • Sudden paralysis or weakness in the face or limbs, especially on one side of the body
  • Sudden problems with balance or walking
  • Sudden vision problems
  • Slurred speech
  • Sudden confusion or problems speaking or understanding simple statements
  • Sudden severe headache with no apparent cause

In addition, if you wake up feeling strange symptoms, Lee said, don't sit around. "People should not wait for any new neurologic deficits in the morning to pass or go away as they become less groggy," he said. "They should find medical attention at once. Even though tPA may not be an option in wake-up strokes, there are still many other treatments that can be given in an emergency room or hospital."

Stroke experts also offer a simple way to aid people remember what to look for if they think they are witnessing a stroke: Think FAST (Face, Arms, Speech, Time):
  • Face means See if the person can smile, or if one side of their face seems to droop.
  • Arms mean can the person raise both arms, or does one side drift downward?
  • Speech means See if the person is able to speak clearly or repeat a simple phrase.
  • Time means Call ambulance immediately if the person exhibits any of these signs.

Study: Ovary Removal Doesn’t Raise Heart Risk

But Findings Oppose Earlier Study Linking Ovary Removal During Hysterectomy With Heart Risk

A new analysis of data from a major women’s health study finds little evidence that ovary removal during hysterectomy increases heart disease risk.

The findings appear to contradict those from another large study in women suggesting a higher risk for heart disease and stroke associated with the practice.

About 600,000 women in the U.S. have their uteruses surgically removed each year. About half of these procedures include removal of the ovaries.

The newly published data from the Women’s Health Study (WHI), which included more than 25,000 women, confirmed that women who had their ovaries removed during hysterectomy developed fewer ovarian cancers than women whose ovaries were not removed.

Keeping ovaries did not appear to be associated with a lower risk for heart disease, osteoporosis, or cancer among the women in the study.

The findings appear in the April 25 issue of the Archives of Internal Medicine.

Choosing Ovary Removal

Ovary removal has benefits for women at high risk for ovarian cancer due to genetic predisposition or family history, and the new analysis appears to tip the scales in favor of removing the ovaries for other women as well.

But it isn’t that simple, experts tell WebMD.

Ovarian cancer is relatively uncommon, while heart disease is the No. 1 killer of older women. More than 10 times as many women die each year from coronary causes as from ovarian cancer.

In the newly published analysis, researchers estimated that one case of ovarian cancer was prevented for every 323 hysterectomies performed with ovary removal.

But keeping ovaries was associated with a clear decrease in heart disease incidence and death from coronary causes in a 2009 analysis of data from the Nurses Health Study (NHS), which included close to 30,000 women.

Health policy researcher Lauren D. Arnold, PhD, MPH, of the University of St Louis, says the contradictory studies can provide a teaching moment for doctors and patients.

“We encourage doctors to practice evidence-based medicine, but that is often interpreted as meaning they need to follow the latest study,” she says. “In this case, we have two very good studies and, for most women, there are still no clear-cut answers.”

Comparing Studies

Two big differences in the studies were the age of the participants and the length of follow-up.

The average age of the women in the Women’s Health Initiative was 63 at enrollment, while women in the NHS trial were enrolled between the ages of 30 and 55. And WHI participants were followed for an average of eight years, while the nurses were followed for 24 years.

NHS researcher William H. Parker, MD, of the University of California, Los Angeles, says the older age of the women in the WHI trial and the fact that the main intent of the study was to examine the impact of hormone replacement treatments on health could have influenced the outcomes.

The surviving women in the NHS trial have now been followed for more than three decades, and Parker says he plans to present an updated analysis within the next two years.

“At this point, like a lot of medicine, the decision about whether to remove ovaries during hysterectomy is an individual one, with each patient bringing her own set of circumstances to the table,” he tells WebMD.

Arnold agrees.

In an editorial published with the study, she and co-author Graham Colditz, MD, of Washington University School of Medicine, write that the subtle differences in the two studies may be easily overlooked by doctors when they counsel patients about the potential benefits and risks associated with ovary removal during hysterectomy.

Arnold says many women facing this decision may not even fully understand that ovary removal is an elective procedure.

“Doctors need to remember that there are no clear-cut answers for most women,” she says.

Heart attacks can happen more serious at Certain times of the day



Study of ahead of print in heart journal reveals that heart attacks can be more serious happened in the morning. About 20% larger area of dead tissue (infarct) people who have heart attacks will occur between 6am and noon. It means that that time is more serious affected by heart attacks than at any other time of the day.

It is well established that a person's 24 hour body clock influences several cardiovascular physiological processes including the incidence of heart attacks, which tend to happen more around the time when a person is waking up from sleep, but what is less known is the extent of damage that this leads to.

Currently, Researchers in Madrid, Spain had determined the impact of time of day of a heart attack on the size of the dead tissue (infarct) caused in patients with an ST segment elevation myocardial infarction (STEMI) - a type of heart attack caused by a prolonged period of blocked blood supply.

They analysed data on 811 patients with a STEMI heart attack admitted to the coronary care unit of Hospital Clinico San Carlos in Madrid between 2003 and 2009. They calculated the size of infarct by looking at enzyme release in patients. Moreover,
coronary artery disease also has a main factor of heart disease

The time of STEMI onset was divided into four 6-hour time periods in phase with 24-hour body clock rhythms.

Patients with the largest infarct size were found to be those who had a heart attack in the dark to light transition period of 6am to noon. These patients were found to have around a 21% higher level of enzymes in this period (which indicated a larger infarct size) than patients who had their heart attack between 6pm and midnight.

The greatest number of patients (269) had their heart attack in the 6am to noon period, followed by 240 patients who had their attack between noon and 6pm, 161 during the 6pm to midnight period, and 141 between midnight and 6am.

They also found that patients with a STEMI that happened in the anterior wall of the heart were left with a larger size of infarct than patients whose heart attacks happened in other locations.

The authors conclude: "If confirmed, these results may have a significant impact on the interpretation of clinical trials of cardioprotective strategies in STEMI."

Generally speaking, people who get heart attacks should be more carefully of maintaining their heart especially at the certain time of the day. To reduce the risk, one of way is they must have a good lifestyle read more about prevention of heart attack and eat health food by avoiding food which contain dangerous for heart disease read what the best food for heart attack.

New Research study of Prevention of diabetes


One of diseases that people currently concern is “Diabetes mellitus”. This kind of disease has been involving people in any ages, means that both young and older people can get diabetes. Moreover, there have a belief for their parents or grandparents have diabetes, it also affects their generation to suffer the same fate. Actually, this is not completely true because the diabetes can be prevented and stop by doing some preventive measures and good lifestyle as well. Here are some ways about diabetes prevention

Researcher showed that the incidence of diabetes mellitus still continues to dramatically increase with the American Diabetic Association estimating that 81 million Americans are currently either diabetic or prediabetic. Diabetes mellitus is a relentless disease. Mostly, the complications of diabetes are extensive due to the progressive damage to the body's entire circulatory system. People with diabetes have a greater risk of developing any diseases like heart disease and/or hardening of the arteries.

According to the World Book Encyclopedia, the average adult human body contains approximately 96,500 kilometers (60,000 miles) of blood vessels. All of your blood vessels are essential to your health because they provide the transportation network that allows your blood to carry nutrients and oxygen to each of your cells. Your network of blood vessels also allows your blood to remove waste products from all of your cells. That is why, blood vessel is very important to be maintained by people who suffer diabetes type 2 in particular. Read two common types of diabetes
Meanwhile, some one reason how diabetes can develop into our body and the main factors is from eating much sugar which can raise level of blood sugar as well as refined carbohydrates than your body can properly use. In fact, your body is forced to produce and release insulin so frequently that one or both of the following conditions may arise:
  1. Your pancreas may not be able to produce enough insulin to effectively deal with your sugar and refined carbohydrate intake.
  2. Your cells may become resistant to the effects of insulin.
One or both of these conditions will eventually lead to a high blood sugar level, which over the long term, will dramatically increase your risk of developing blockages in your network of blood vessels. The best way for reducing your risk of developing diabetes can be read here and be alert to maintain your body regularly by doing important things.

Recent study said that development of insuline resistance has a link to immune system which may help drive diabetes type 2. "The main point of this study is trying to shift the emphasis in thinking of type 2 diabetes as a purely metabolic disease, and instead emphasize the role of the immune system in type 2," said study co-author Dr. Daniel Winer, an endocrine pathologist at Toronto General Hospital in Canada. When the research began, Winer was a postdoctoral fellow at Stanford University in California. The less common form of the disease, type 1 diabetes, occurs when the immune system mistakenly destroys the insulin-producing beta cells in the pancreas. This type of diabetes is considered an autoimmune disease, and isn't linked to how much a person weighs. Although the causes of type 2 haven't been clear, it's known that the disease runs in families, suggesting a genetic component. Also, while type 2 is strongly linked to increased weight, not everyone who is overweight gets type 2 diabetes. Read more here to get deep explanation

Treat Depression to Boost Diabetes Self-Care: Study

FRIDAY, April 22 (HealthDay News) -- Treating diabetes patients' depression boosts their overall health, according to a new study.

It included 145 people with type 2 diabetes and depression who received a year-long depression intervention that included 12 weeks of cognitive behavioral therapy over the phone, followed by nine monthly booster sessions. They also took part in a walking program.

They were compared to a control group of 146 diabetes patients with depression who received usual diabetes care.

At the end of the year, depression symptoms were in remission for 58 percent of the patients in the intervention group and 39 percent of those in the control group, said the researchers at the VA Ann Arbor Healthcare System and the University of Michigan Health System.

The intervention program also led to lower blood pressure, an increase in walking of about four miles a week and improvement in general quality of life.

However, most patients already had good blood sugar control at the outset of the intervention, so A1C levels, a measure of blood sugar control, did not drop.

The study appears online ahead of print in the journal Medical Care.

Depression and diabetes often go hand in hand, and depression can be a major problem for people with diabetes because it makes them less likely to follow their medicine schedule or exercise program, the researchers explained.

"Depression is a common, treatable issue for many people who have diabetes," said study lead author John Piette, a senior research scientist at the VA and professor of internal medicine at the University of Michigan Medical School, in a university news release.

"Unfortunately, most busy clinics cannot provide the level of intensive care these patients need. This study shows that telephone-delivered counseling can improve patients' access to effective depression care, improve their cardiovascular health and get them moving again," he added.

Heavy Teens at Increased Risk of Heart Disease Years Later

Teenage boys who are even slightly overweight face an increased risk of heart disease later in life, even if they slim down as adults, according to a new study in the New England Journal of Medicine. 

Regardless of their adult weight, men who were obese as teenagers were nearly seven times more likely than their slimmest peers to be diagnosed with heart disease in their mid-30s, the study found. Heavier-than-average teens whose body mass index was in the normal range were at increased risk as well. (Body mass index, or BMI, is a ratio of height to weight that provides a rough estimate of body fat.)

The good news is that the same was not true of diabetes. A man’s BMI as an adult, but not as a teen, was linked to an increased risk of developing type 2 diabetes, so slimming down by eating right and exercising appears to go a long way toward preventing the onset of the disease, the researchers say. 

“For those who don’t become obese as adults, the risk of diabetes goes down, but for heart disease this is not the case,” says the lead author of the study, Amir Tirosh, MD, an endocrinologist at Brigham and Women’s Hospital, in Boston. “You don’t get rid of the risk just by reducing the weight. The body remembers when we were running around with a higher BMI.”

Current weight and recent weight changes strongly influence the risk of developing type 2 diabetes. By contrast, the findings suggest, the narrowing and hardening of the arteries (atherosclerosis) that characterizes heart disease and often goes hand in hand with obesity—both are aggravated by a poor diet and sedentary lifestyle—is gradual and difficult to reverse, even with weight loss.

It’s important to keep in mind that being overweight is not solely responsible for heart disease or diabetes, says Daniel Marks, MD, a pediatric endocrinologist at Oregon Health and Sciences University, in Portland. Nutrition, exercise, and other lifestyle choices, he says, have a “much greater impact” on risk than body size alone.

Two people with the same BMI can have very different risks for diabetes and heart disease if one of them exercises regularly and the other does not, says Dr. Marks, who was not involved in the new study. “BMI is a proxy marker for poor lifestyle choices,” he explains. “But it’s the lifestyle choices that will get you in the end. We all need to have healthier lifestyles.”

Indeed, even some boys in the study whose BMIs were considered “normal” were at increased risk of heart disease as adults. The Centers for Disease Control and Prevention defines kids and teens with a BMI between the 5th and 85th percentile for their age as normal, but Tirosh and his colleagues found that boys with BMIs as low as the 50th percentile—which equates to a BMI of about 20—were at increased risk.

“For patients at the higher end of the normal range, doctors should be addressing risk factors such as family history of heart disease and smoking,” Dr. Tirosh says.

Brain tumor radiation tied to later infertility

NEW YORK (Reuters Health) – Low doses of radiation therapy to the head, for brain tumors or some other cancers, might make it slightly harder for girls to have babies when they get older, a new study shows.

Doctors already knew that higher doses of radiation for these conditions can interfere with a woman's fertility, because it can destroy cells in the brain that control how her ovaries produce eggs, said Dr. Daniel Green, a cancer doctor at the St. Jude Children's Research Hospital in Memphis, Tennessee.

"It was not known that more modest doses can possibly have an effect on fertility," Green, who was a co-author on the study, told Reuters Health.

Most of the girls in the study, about 6 out of 10, had either leukemia or a brain tumor. Others had cancers of the lymph nodes, bone, or muscles.

None of the girls had radiation of their ovaries, which might have affected their fertility.

Instead, Green and his colleagues wanted to know what happens to the fertility of girls who have radiation that reaches two glands next to the brain, the pituitary and the hypothalamus.

Leukemia -- cancer of the white blood cells -- is sometimes treated this way if cancer cells show up in the fluid that bathes the spinal cord and the brain.

"For brain tumors, radiation has always been part of the treatment," although doctors are using more chemotherapy now than they have in the past, said Dr. Jason Fangusaro, a pediatrician at Children's Memorial Hospital and Northwestern University Feinberg School of Medicine in Chicago, Illinois.

This type of radiation isn't used for leukemia patients as often now as it once was, Fangusaro, who wasn't involved in the study, told Reuters Health.

But there are "many women who were treated for this 10 or 15 years ago" who could be at risk for fertility problems, Green said, and doctors don't know exactly what their numbers are.

In their study, Green and colleagues sent questionnaires to about 3,600 women who had cancer as girls, between 1970 and 1986, and also to about 2,100 of their sisters, asking about any pregnancies the women might have had.

About 3 of every 10 former cancer patients had been pregnant at least once, compared to about 5 out of 10 of their sisters, the researchers report in the medical journal Fertility and Sterility. This small difference, they say, could have been due simply to chance.

Green's group did not analyze how many times women tried to become pregnant.

But the actual pregnancy rate was significantly lower for some of the women - and not just those who received the highest doses of radiation to those two glands near the brain.

The highest doses involved more than 27 units of radiation, known as Grays. But women exposed to at least 22 units of radiation also had significantly lower odds of pregnancy; they had about a third fewer pregnancies compared to survivors who hadn't had been treated with radiation at all.

A dose of 22 Grays is more than 200,000 times higher than the amount of radiation in an average chest X-ray.

Leukemia is the most common type of cancer in kids, and about 3,300 new cases were expected in 2010, according to the Leukemia and Lymphoma Society.

And kids develop about 3000 to 4000 new brain tumors a year, Fangusaro said. 

When cancer survivors do become pregnant, "it's considered a high-risk pregnancy, and they need to be seeing a specialist who knows about helping the woman ovulate," and maintaining the pregnancy with the right hormone therapy, said pediatrician Dr. Susan R. Rose. Rose, from Cincinnati Children's Hospital in Ohio, was not involved in the study. 

Research advances have improved the odds of survival after childhood cancers. So if a girl was diagnosed with cancer in the past, it is likely she's still alive and may be facing fertility problems, Rose told Reuters Health. 

"It's also likely that if she didn't get (the radiation) treatment, she might have not survived," she said. "It's part of a lifesaving therapy."
