Great American Smokeout '09
Time to Quit
November 19, 2009
American Cancer Society sets Nov. 19 as annual day to 'butt out' for good. The less you smoke, the more birthdays you'll have, says the American Cancer Society as it encourages smokers to quit on Thursday, the day of the 34th Great American Smokeout.
Research shows that smokers who quit at age 35 gain an average of eight years of life expectancy, and those who quit at 55 gain about five years. Even long-time smokers who quit at age 65 gain three years.

Genital Herpes May Never Go Dormant
November 18, 2009
Study finds low level shedding may be continuous, infection state unclear. Herpes, the sexually transmitted disease that causes genital lesions, never truly goes into a dormant state, new research suggests.
As a matter of fact, even when it's not causing an outbreak, the virus is shedding tiny bits of itself in the genital tract.
While the study did not specifically address whether or not the very small amounts of virus being continually shed are enough to infect someone else, the findings have the potential to change the way in which scientists view the life cycle of the disease.

MS Need Not Preclude Pregnancy
November 18, 2009
Study finds complications no greater overall than for other women. New research suggests that having multiple sclerosis puts pregnant women at slightly higher risk for giving birth via cesarean deliveries or having babies that grow at a slower rate in the womb.
But the researchers, whose findings were published online Nov. 18 in Neurology, also reported that pregnant women with MS were not more likely than other women to develop such conditions as preeclampsia or premature rupture of membranes.

Heartburn Drugs Can Thwart Popular Blood Thinner
November 17, 2009
Combination can increase the risk of heart attack and stroke, U.S. officials say. Combining the antacid Prilosec with the popular blood thinner Plavix (clopidogrel) can cut the effectiveness of Plavix by half, putting patients at risk for heart attack or stroke, U.S. health officials said Tuesday.
Folic Acid Fortification Might Boost Cancer Risk
November 17, 2009
Norwegian study found supplementation raised chances of disease by 21%. Although folic acid fortification of foods can prevent many birth defects, it may also increase the risk for developing cancer, Norwegian researchers report.
Since 1998, many countries have mandated folic acid (vitamin B9) fortification of foods to decrease the incidence of neural-tube defects in newborns. By October 2009, the flour produced in these countries, plus the flour that is fortified voluntarily, represented 30 percent of the world's wheat flour produced in large mills.

Guidelines Delay Start of Mammograms to Age 50, Then Every Other Year
November 16, 2009
Cancer Society, others voice strong disapproval of federal recommendations. Women don't need to start having mammograms to screen for breast cancer until they're 50, and they only need to have those exams every other year, new government guidelines suggest.
Also, breast self-exams, which women have been urged to do routinely, have not helped lower the death rate from breast cancer, the guidelines add.
Not all agree with the revised recommendations, however.

Gene Linked to Breast Cancer Might Boost Heart Health
November 16, 2009
When BRCA1 is deactivated, it can lead to atherosclerosis, or hardening of the arteries, mouse study suggests. The over-activity of a gene known to boost a woman's risk for breast cancer may have a good side, making arteries healthier, a new study suggests.
The study, performed in mice, also found that when this gene, called BRCA1, is turned off, it promotes an inflammation that can lead to atherosclerosis or hardening of the arteries.
Although there has been no previous observation of increased cardiovascular death specifically in the large number of people who carry the BRCA1 mutation, there has been a surprising suggestion of higher non-cancer death in this population, noted study senior author Dr.

Gestures Processed in Brain's Language Center
November 14, 2009
Talking with your hands could be linked to evolution, research suggests. Words and gestures are processed in the same areas of the brain, a finding that may improve understanding of the evolution of language, researchers say.
In the study, MRI was used to monitor the brain activity of 20 volunteers as they watched video clips of a person either acting out gestures or voicing phrases that matched the gestures' meanings. Both the gestures and words triggered high levels of activity in the inferior frontal and posterior temporal areas, which are the language regions of the brain.

Chinese Scientists Develop Database on the Liver
November 13, 2009
Information on proteins could help guide treatments for hepatitis and more. Chinese scientists report that they have created an extensive database about proteins produced by genes in the human liver, an endeavor they say could become the foundation for new treatments for liver disease.
To develop the database, reportedly the largest of its kind for any organ, the researchers examined 10 liver-tissue samples from volunteers and identified 6,788 proteins, half of which had never before been encountered. One unexplained discovery, they said, was that many seem to be connected to diseases of the nervous system.

22 Million Sickened by Swine Flu in 6 Months
November 12, 2009
Revised estimation method gives clearer picture of pandemic, CDC says. At least 22 million Americans have come down with the H1N1 swine flu since the virus first surfaced in April and approximately 3,900 people have died, including an estimated 540 children, federal health officials reported Thursday.
While these numbers represent a significant jump in the numbers of sick, hospitalized and dead from previous figures, they don't mean that the swine flu has suddenly gotten worse. Instead, the new numbers are based on extrapolations from laboratory-confirmed cases of swine flu.

Trial Data on Anti-Seizure Drug Might Have Been Manipulated
Report
November 11, 2009
Study found outcome measures differed between company documents, published reports. An unusual look at internal documents from a pharmaceutical company suggests that clinical data was manipulated to make a popular anti-seizure drug, gabapentin (Neurontin), look more effective than it actually was, thereby increasing possibilities for its off-label usage, according to a new report.
"This means we're not seeing the full picture, and the picture we are seeing is suspect because perhaps there was selective reporting of outcomes so that only the positive outcomes were reported," said Kay Dickersin, senior author of a paper reporting the alleged deception in the Nov. 12 issue of the New England Journal of Medicine.

Cataract Surgery Doesn't Worsen Macular Degeneration
Study

Link likely due to fact that both eye conditions are age-related, researchers say. Cataract surgery doesn't appear to speed the progression of age-related macular degeneration (AMD), according to a new study that challenges the belief that treating one cause of vision loss worsens the other.
"Because both conditions are strongly age-related, many individuals with cataract also have AMD," wrote Li Ming Dong, of Stony Brook University School of Medicine in New York, and colleagues. "There has been a long-standing controversy among clinicians as to whether cataract surgery is contraindicated in eyes with non-neovascular AMD.

Stem Cells May Offer Alternative to Lung Transplants
November 06, 2009
Novel protocol could provide new lung tissue for certain patients, researchers say. Belgian scientists who used embryonic stem cells to create lung tissue say this technique could provide an alternative to lung transplants for patients with chronic obstructive pulmonary disease (COPD) and cystic fibrosis.
This is the first time it's been shown that embryonic stem cells can be converted into airway epithelial-like cells without the use of specific growth factors or embryoid body formation. The researchers achieved this using an "air-liquid interface" system that mimics the conditions found in an adult trachea.

Early Relapse of MS May Mean Fewer Issues Later
November 06, 2009
Short-term limitations seem to wane as years go by, researcher says. New research suggests that people with multiple sclerosis who have relapses within five years of developing the disease are more likely to suffer from severe limitations in the short term than others with the condition.
The findings, published Nov. 4 in Neurology, show that people with the disease who relapse within five years of developing it are nearly 50 percent more likely to need a cane to walk during that time period.

Health Fears Are Nothing to Sneeze At
November 06, 2009
After witnessing a sneeze, people worry more about flu, heart attacks, accidents and crime, study finds. It may sound hard to believe, but just one sneeze is enough to increase your fear not just of contracting flu, but also of dying from a heart attack at an early age, dying from an accident or being the victim of a fatal crime, new research shows.

Early Morning Colonoscopies May Find More Polyps
November 06, 2009
Study suggests differences in patient preparation and doctor fatigue play a role. Early morning colonoscopies detect more polyps than colon cancer screenings done later in the day, and the number of polyps found decreases by the hour as the day progresses, a new study has found.
Removing polyps is believed to reduce the risk of colon cancer by 60 to 90 percent.
Researchers from the University of California, Los Angeles, analyzed data on 477 people who had colonoscopies in a one-year span at a Veterans Affairs hospital.

Treatment after oxygen deprivation accounts for better motor skills later, study suggests. Babies who are deprived of oxygen at birth often go on to have lifetime disabilities, but research has shown that cooling infants can help prevent problems.
Now, a new study reports that the cooling actually reduces the number of brain lesions in the babies.
Oxygen starvation at birth can cause a condition called hypoxic-ischemic encephalopathy, which can be fatal.

Swine Flu Virus Dominant Strain Worldwide
WHO
November 05, 2009
Agency says pathogen continues to target younger adults, producing mild-to-moderate illness. The H1N1 swine flu virus is now the predominant flu strain worldwide, although it shows no signs of becoming more virulent and continues to produce mild-to-moderate symptoms in most people, the World Health Organization's flu chief said Thursday.
In some countries, the swine flu accounts for up to 70 percent of the flu viruses being sampled, Dr. Keiji Fukuda said during a press briefing, the Associated Press reported.

Rest Easy. When It Comes to Swine Flu, Your Pet Is Safe
November 05, 2009
Recent reports of H1N1 in a cat or pigs are likely very rare, experts say. When the news broke on Wednesday that a domestic cat had come down with H1N1 swine flu, probably transmitted to the feline by sick owners, many people no doubt wondered how vulnerable their own pets were to the illness.
So, does Fluffy or Fido need protecting from this strain of flu? The answer, experts say, is basically no.
While the H1N1 flu currently circulating can jump easily from person to person, it does not travel well from humans to animals or animals to humans, except in a few rare instances.

Will New Anemia Drug Top Current Treatments?
November 04, 2009
Designed for a rare condition, it might have a wider application, experts say. A new drug designed to treat patients with a rare form of anemia could possibly have wider applications, perhaps replacing other anemia treatments that have been linked to an increased risk of death, cancer and stroke, experts say.
The drug, Hematide, was successful in treating patients who have pure red-cell aplasia, a condition caused by antibodies to a hormone needed to produce red blood cells. It's a "devastating condition that many patients have died from and ties patients to blood transfusions every two weeks for the rest of their life," said lead researcher Dr.

Study reports successes, especially for those with good lung function. Three-year survival was 100 percent for people with early-stage lung cancer and good lung function who were treated with radical stereotactic radiosurgery using CyberKnife, according to a new study funded by the product's maker.
Standard care for people with small lung tumors calls for surgical removal of the affected lobe, but some people cannot have surgery because of other medical conditions, such as heart disease or emphysema.
"Our goal has been to find a reasonable option for patients who don't want or can't tolerate surgery," the study's lead author, Dr.

Drug Could Help Treat Small HER2-Positive Breast Tumors
November 03, 2009
Researcher urges studies to determine benefits of anti-HER2 therapies. Women with a relatively uncommon type of breast cancer are significantly more likely to face its recurrence and spread, but researchers now say these women may benefit from treatment with the breast cancer drug Herceptin.
Two studies, from the United States and Italy, examined cases of women with small (1 centimeter or less in diameter) HER2-positive breast cancers that hadn't spread to the lymph nodes. The researchers found that the cancer is more than two times more likely to recur in HER2-positive women than in women with HER2-negative breast cancers.

Experts have long known that "low-tar" and "light" cigarettes aren't any healthier than regular cigarettes, and new research suggests they have another drawback: People who switch to them are less likely to quit, even those who switch specifically because they want to stop smoking.
In fact, "switching to ['light' cigarettes] for any reason is associated with continuing to smoke," said study author Dr. Hilary Tindle, a researcher at the University of Pittsburgh's Division of General Internal Medicine.

Anemia Drug May Raise Stroke Risk in Kidney Patients
November 02, 2009
Use of Aranesp should be reserved for the most seriously ill, experts say. A drug designed to fight anemia appears to double the risk of stroke in patients with diabetes and kidney disease without substantially improving their quality of life, a new study finds.
Darbepoetin alfa, marketed as Aranesp and known as an erythropoiesis-stimulating agent (ESA), is often prescribed for diabetic patients with chronic kidney disease and mild anemia.
"The benefits we assumed we would have by treating anemia were less striking and the risks were more striking," said lead researcher Dr.

Exposure to Holocaust May Have Raised Cancer Risks

Survivors offer clues to the impact of severe physical, psychosocial suffering, researchers say. Among Jewish survivors of World War II, those who were potentially exposed to the Holocaust have an increased risk of cancer, likely due to physical and mental stress, an Israeli study has found.
University of Haifa researchers compared cancer rates in more than 300,000 Israeli Jews who were born in Europe and immigrated to Israel either before World War II (non-exposed) or after the war (potentially exposed).
Compared to the non-exposed group, those in the potentially exposed group had a statistically significantly increased risk for cancer, especially breast and colorectal cancer, the researchers found.

Sperm May Play Role in Transmission of HIV
October 26, 2009
Semen isn't the only way men spread virus during sex, new research shows. New research suggests that sperm, not just semen, can transmit the virus that causes AIDS to immune cells in the body and, in fact, sperm may play a major role in transmission.
Scientists already know that men infected with HIV, the virus that causes AIDS, can spread the disease through their semen, the fluid that carries sperm. But it hasn't been clear what role sperm itself plays, especially considering that men who don't produce sperm, such as those who have had vasectomies, can transmit the virus.

HPV Vaccine No More Painful Than Other Shots
October 23, 2009
Reports that injection sting is excessive disputed in U.S. study. There have been reports that injections of the human papillomavirus (HPV) vaccine are especially painful, but a new study finds that they don't hurt more than any other shots.
Public health officials worried that reports of excess pain might prevent young women from getting the vaccine, which protects against a virus that can cause cervical cancer, some other kinds of cancer and genital warts. There was also concern that some women might not get all three required doses.

Light Touch Helps Grip of MS Patients
October 23, 2009
Study shows ways to optimize hand movements. Using a gentle touch may help make it easier for people with multiple sclerosis to pick up and hold objects, a new study suggests.
People with MS use excessive force when lifting objects, which can lead to fatigue and make everyday tasks difficult, physical therapists from the University of Illinois at Chicago explained in a school news release.
Using the finger of the opposite hand to apply a gentle touch to the affected hand may help improve control and coordination, they stated.

Babies Spot Human Speech at 5 Months
October 23, 2009
They easily distinguish language from animal sounds, researchers say. Children as young as 5 months old are able to tell the difference between human speech and monkey calls, a new study has found.
Researchers showed 5-month-old infants from English- and French-speaking homes pictures of human faces and rhesus monkey faces paired with either human speech or monkey calls. The infants looked longer at pictures of human faces when human speech was presented and longer at monkey faces when monkey calls were played.

Production Problems Plague Delivery of Swine Flu Vaccine
October 23, 2009
Despite significant shortfall, CDC says all Americans who want shot will be able to get one, eventually. As reports of swine flu infections continue to pour in from across the United States, health experts labored Thursday to explain why delivery of stocks of the long-awaited H1N1 vaccine are falling behind schedule.
Federal officials had projected that 40 million doses would be on hand by Oct. 15, but not even 13 million doses had arrived by Tuesday.

Guidelines Urge Use of Erectile Dysfunction Drugs
October 22, 2009
Which product to prescribe depends on patient preferences, experts say. Doctors should prescribe oral phosphodiesterase type 5 (PDE-5) inhibitor drugs, such as Viagra, Cialis and Levitra, for men with erectile dysfunction, unless the patient is on nitrate therapy, according to a clinical practice guideline issued by the American College of Physicians.
The type of erectile dysfunction (ED) drug prescribed should be based on the individual preferences of patients, including cost of medication, ease of use and types of side effects, the authors noted.
"The evidence is insufficient to compare the effectiveness or adverse effects of different PDE-5 inhibitors for the treatment of ED because there were only a few head-to-head trials," guideline lead author Dr.

Drug Use in Teens May Damage Memory Years Later
October 22, 2009
Young rats given amphetamines suffered short-term losses as adults, study finds. Rats develop memory loss in adulthood after receiving high doses of amphetamines during their "teen" years, new research shows.
Exposure to the drugs during adolescence has a more severe impact on short-term memory than being exposed as adults, researchers found in a study that was to be presented this week at the Society for Neuroscience annual meeting, in Chicago.
"Animals that were given the amphetamine during the adolescent time period were worse at tasks requiring working memory than adult animals that were given the same amount of amphetamine as adults," study co-author and psychology professor Joshua Gulley of the University of Illinois at Urbana-Champaign, said in a school news release.

Study Finds Less Toxic Treatment for Myeloma
October 22, 2009
Lower dose of standard medication leads to better outcome, researchers say. Cancer researchers say they have a better treatment for patients with newly diagnosed multiple myeloma than the current standard therapy.
Their study finds that treatment with lenalidomide plus low-dose dexamethasone is associated with better short-term survival and with lower toxicity than lenalidomide plus high-dose dexamethasone, which is the mainstay of therapy for the bone marrow cancer.
The study included more than 400 patients with untreated, symptomatic myeloma who received lenalidomide (25 milligrams for 21 days) plus a high dose of dexamethasone (40 milligrams on days one to four, nine to 12, and 17 to 20 of a 28-day cycle), or who received lenalidomide on the same schedule with a low dose of dexamethasone (40 milligrams on days one, eight, 15 and 22 of a 28-day cycle).

Breast Cancer Gene Tied to Diagnosis at Younger Age
October 16, 2009
Researchers concerned that disease may be developing earlier. Women with a high genetic risk of developing breast cancer are being diagnosed sooner than similar women in the past, which may suggest that tumors are developing earlier in the younger generation, researchers say.
The finding, presented at the 2009 Breast Cancer Symposium, held last week in San Francisco, could potentially affect how women are screened for breast cancer.
About 5 percent to 10 percent of breast cancer cases are thought to be connected to a genetic mutation that's also linked to ovarian cancer.

Race Not a Factor if Breast Cancer Chemo Succeeds
October 14, 2009
All women have similar outcomes when there's no sign of disease following treatment, study finds. Among women with locally advanced breast cancer who undergo the same class of chemotherapy, race doesn't affect the odds of having no sign of disease at surgery, a new study finds.
Having no sign of the disease is considered a good sign that bodes well for a woman's prognosis, although it's not a guarantee that the cancer has vanished for good, the study authors noted.
"Our findings confirm [that having no sign of the disease] is a strong prognostic indicator and a surrogate for good survival, despite a patient's race, and that it's vital we continue to strive towards achieving this milestone for all women with breast cancer," said study co-author Dr.

Severe Swine Flu Could Lead to Blood Clots in Lungs
Study
October 14, 2009
Researchers say CT scans may be needed to spot the risk People who are severely ill with the H1N1 swine flu run the risk of blood clots in the lungs, University of Michigan researchers say.
And because standard chest X-rays may not be able to spot the potentially fatal condition, more sophisticated CT scans may be needed to identify the risk, the researchers said.
Technically called a pulmonary embolism, the condition occurs when one or more arteries in the lungs become blocked.

Mother-to-fetus transmission still likely rare, experts say, since the placenta acts as a barrier to cells from the mother, and the fetal immune system would reject and destroy cancer cells.
"Some 30 times reported in the past, mother and infant have appeared to share the same cancer, usually leukemia or melanoma," noted lead researcher Dr.

With Hormone Therapy, Tender Breasts May Signal Cancer Risk
October 12, 2009
Symptom might warrant a reassessment of treatment, experts suggest. Breast tenderness in women taking estrogen/progestin hormone replacement therapy could signal increased chances of developing breast cancer, a new study says.
Women taking estrogen plus progestin who reported developing breast tenderness after starting the hormone therapy were 48 percent more likely to develop invasive breast cancer than women on hormone therapy who did not experience breast tenderness.
Researchers said more study is needed before they would recommend that women who experience this symptom discontinue taking the hormones.

Swine Flu Can Move Quickly to Severe Illness
October 12, 2009
Canadian, Mexican studies suggest U.S. hospitals need to be ready for surge of cases. Canadian and Mexican intensive care units were swamped with patients who rapidly became critically ill with H1N1 flu this past spring and summer, new reports find.
Many of these patients were relatively healthy adolescents and young adults who needed to be treated in an intensive care unit (ICU) within a day or two of being admitted to the hospital, note doctors from both countries. Many patients required mechanical ventilators, say the reports, slated to be published in the Nov.

In Some Cities, Spring Swine Flu May Be Easing Fall Outbreak
October 08, 2009
Immunity from prior exposure may make H1N1's return less severe, experts say. New York, Philadelphia and other cities hit hard by H1N1 swine flu last spring aren't seeing as much of it now, even though outbreaks are occurring in all 50 states.
The possible reason: Many people in these spring-outbreak epicenters have already gained some immunity to H1N1, and this "herd immunity" is keeping a wider fall outbreak at bay, experts say.
According to a report released Thursday by the New York Times, health officials in New York City, Boston and Philadelphia say they are seeing less swine flu now than they did during the initial outbreak.

HIV Patients More Prone to 7 Kinds of Cancer
October 08, 2009
Study found early treatment of infection could slow start of malignancies. The weakened immune systems of people with HIV puts them at increased risk for at least seven types of cancer, but early diagnosis and treatment of HIV infection could help delay the onset of some of these cancers, a new study suggests.
French researchers examined the incidence of three AIDS-defining cancers (Kaposi's sarcoma, non-Hodgkin's lymphoma and cervical cancer) and four non-AIDS-defining cancers (Hodgkin's lymphoma, lung cancer, liver cancer and anal cancer) in 52,278 HIV-infected people.
The study authors also analyzed the association between immunodeficiency, viral load, antiretroviral treatment and the onset of the seven cancers.

Birth Control Pills Might Alter Mate Selection
Study
October 07, 2009
Review suggests it could hinder reproduction in the future. Could birth control pills be taking human evolution in a whole new, and possibly detrimental, direction?
A review of past research finds that, by altering hormonal cycles, the pill might affect choice of mates among members of both genders in a way that could hinder successful reproduction in the future.
"The use of the pill by women, by changing her mate preferences, might induce women to mate with otherwise less-preferred partners, which might have important consequences for mate choice and reproductive outcomes," said Alexandra Alvergne, lead author of a study appearing in the October issue of Trends in Ecology & Evolution.
"One prediction is that offspring of pill users are more homozygous than expected, possibly related to impaired immune function and decreased perceived health and attractiveness," according to the report by Alvergne, a postdoctoral research associate in the department of animal and plant sciences at the University of Sheffield in England, and colleague Virpi Lummaa.

Seasonal Flu Vaccine May Lessen Swine Flu Impact
October 07, 2009
But it won't fully protect people from the H1N1 virus, experts say. The seasonal flu vaccine may offer partial protection against the pandemic H1N1 swine flu, but not enough to prevent a person from catching the swine flu, Mexican researchers say.
In a study of hospital patients during the H1N1 epidemic in Mexico City last spring, the researchers found that those who had had a seasonal flu shot and were infected with the H1N1 flu had significantly milder cases than those who had not received a seasonal flu shot.
For the study, a group led by Dr.

Pre-Birth Exposure to 1918 Flu Raised Heart Risks, Study Finds
October 01, 2009
Whether same will hold true for current H1N1 strain remains a mystery. People exposed to the deadly 1918 Spanish flu pandemic while still in their mother's womb were about 20 percent more likely to have heart disease 60 years later, a new study has found.
The flu outbreak in 1918 killed 20 million to 40 million people worldwide, including 500,000 in the United States. That flu, like the current H1N1 swine flu pandemic, began as a mild disease, but it then came back in a much more lethal form.

Swine Flu Could Create Hospital Bed Shortage
October 01, 2009
Report finds demand could exceed supply in 15 states. There could be a shortage of hospital beds in 15 states if 35 percent of Americans get sick from the H1N1 (swine) flu virus, and 12 other states could reach or exceed 75 percent of their hospital bed capacity, a study released Thursday shows.
The number of people who could get sick with H1N1 flu in the United States ranges from a high of 12.9 million in California and a low of 186,434 in Wyoming, and the number of people who are hospitalized could range from a high of 168,025 in California to a low of 2,485 in Wyoming, according to the report from the non-profit group Trust for America's Health.

Children's Belly Aches Don't Disappear With Antidepressant
October 01, 2009
Elavil worked no better than placebo in study of kids with gastrointestinal disorders. Contradicting some previous research in adults, a new study suggests that the antidepressant amitriptyline (Elavil), is no better than a placebo at treating painful gastrointestinal disorders in children.
"The high placebo effect we identified in this study suggests that further studies of the use of certain antidepressants in children with functional bowel disorders are needed. While several trials have demonstrated a beneficial effect of antidepressants, including amitriptyline, for the treatment of irritable bowel syndrome in adults, more research is needed to determine how effective this drug is, if at all, in children," study author Dr.

CDC Links Infections With Swine Flu Deaths
September 30, 2009
Nearly a third of U.S. victims were also infected with pneumococcus or other bacteria, agency reports. Bacterial co-infections are common among people who have died of H1N1 swine flu in the United States and probably contributed to their deaths, according to a new federal government study.

Non-AIDS-Related Cancers Growing Among HIV Patients
September 30, 2009
Possible reasons for increased rates explored by researchers. Non-AIDS-related cancers such as anal and lung cancer have become more common among HIV patients than among people without HIV since antiretroviral therapies were introduced in the mid-1990s to treat people with the virus, U.S. researchers say.
Breast Cancer Death Rates Continue to Drop 2% Annually
September 30, 2009
But mortality still higher among black women than white women, U.S. report says. Fewer women in the United States are dying from breast cancer, but disparities in death rates still exist between whites and blacks, a new report shows.
Deaths from breast cancer have dropped more than 2 percent each year since 1990. And in the past decade that decline in deaths has been shared by black, Hispanic and white women.

Sexual Satisfaction May Lead to Greater Well-Being in Women
September 30, 2009
But frequency of activity cannot be considered a reliable indicator, researchers say. Women who are happy with their sex lives have higher well-being scores and more vitality than women who are sexually dissatisfied, Australian researchers say.
Their study included 295 women, aged 20 to 65, who were sexually active more than twice a month.
"We wanted to explore the links between sexual satisfaction and well-being in women from the community, and to see if there was any difference between pre- and postmenopausal women," study author Dr.

Social Isolation Adversely Affects Breast Cancer
September 29, 2009
In mouse study, those living alone had larger tumors than those in groups. A socially isolated, stressful environment can speed up the growth of breast cancer, researchers studying the effects of stress in animal models reported Tuesday.
Social isolation can actually change the expression of genes important in the growth of mammary gland tumors, according to Dr. Suzanne D.

Younger Women With Colon Cancer Outlive Men
September 29, 2009
Estrogen could explain discrepancy in survival rates, researchers say. A new study suggests that estrogen or other hormones could help younger women with colorectal cancer live longer than men with the disease.
"We've known for a while that estrogen prevents colorectal cancer, but this is the first study to suggest it may improve outcomes once you have colorectal cancer," said study co-author Dr. Heinz-Josef Lenz, co-director of gastrointestinal oncology and colorectal cancer at the University of Southern California/Norris Comprehensive Cancer Center, in a statement.

1918 Flu Closings May Provide Lessons for Today
September 29, 2009
Cities weighing swine flu school closures should review past practices, researchers say. An analysis of disease control measures used during the 1918 influenza pandemic offers lessons for dealing with the issue of school closures this fall in response to the H1N1 swine flu pandemic, say U.S. researchers.
Men Not Being Told Enough About PSA Tests
September 28, 2009
Pros, cons of cancer screen not understood, research shows. Most men are not being told the pros and cons of PSA tests, two new studies find.
Although PSA tests can detect prostate cancer, they can't predict which cancers are aggressive and which are so slow-growing that they don't need to be treated. This leads to overtreatment, which can have immediate consequences, such as impotence and incontinence, and only a tiny increase in survival, researchers say.

Docs Miss Test Results -- Even With Alerts
September 28, 2009
Communication woes still plague medical system, researchers find. Even an advanced, computerized medical-record system with alerts cannot guarantee that patients will receive timely follow-up care when imaging tests turn up signs of trouble, new research suggests.
"Our findings suggest that an electronic medical record that facilitates transmission and availability of critical imaging results to the health care provider through either automated notification or direct access of primary report does not eliminate the problem of missed test results even when one or more health care providers read the results," write the authors of a study in the Sept. 28 issue of the Archives of Internal Medicine.

More Women Having Other Breast Removed
September 28, 2009
But experts say there's no proof that procedure extends survival of cancer patients. Many more women are deciding to have a healthy breast removed after being diagnosed with breast cancer in the other.
But there's little evidence to suggest that this practice is actually beneficial in terms of improving survival, say the authors of a study published Sept. 28 in Cancer.

Vitamin D May Improve Melanoma Survival
September 27, 2009
But levels are too low in many Americans, researchers say. Higher levels of vitamin D are linked to less severe, less deadly melanoma lesions in people with skin cancer, new research suggests.
The findings provide more support for the idea that vitamin D is crucial to skin health. Many Americans, however, don't get enough of it, perhaps because they limit sun exposure and drink less milk than in the past.

Studies Find PSA Screening Unreliable
September 25, 2009
Men need to know pros, cons to make informed choice about prostate cancer test, experts say. The inability of the prostate specific antigen (PSA) test to distinguish between deadly and harmless prostate cancers makes it unusable as a population-wide screening tool, new research claims.
Because of its unreliability, results from the test lead to overdiagnosis and overtreatment, according to two reports in the Sept. 25 online edition of BMJ.

New Hope for Treatment of Pancreatic Cancer
September 25, 2009
By inhibiting key enzyme, researchers shrank tumors, prolonged survival in mice. Inhibiting the action of an enzyme called TAK-1 reverses pancreatic cancer resistance to chemotherapy, a finding that could lead to the development of a new way to treat the disease, researchers say.
Pancreatic cancer is resistant to every currently available anti-cancer treatment.
"During the past few years we have been studying the role played by a cytokine or regulatory protein called transforming growth factor-beta [TGFbeta] in the development of pancreatic cancer.

New Treatment May Beat Melanoma
September 24, 2009
In trials, advanced cancers shrunk rapidly, researchers say. An experimental treatment for advanced melanoma promotes rapid shrinking of tumors, according to a new study.
The phase I extension trial includes patients with the cancer-causing mutation of the BRAF gene, which is associated with about 50 percent of melanomas and 5 percent of colorectal cancers.
The patients were given 960 milligrams of PLX4032 twice a day.

Letter Warns About Tricky Dosing With Liquid Tamiflu for Kids
September 24, 2009
Meanwhile, CDC says rapid test for swine flu not effective. Doctors warn that parents across the country could give the wrong dose of Tamiflu to their children as treatment for the H1N1 swine flu because the dosing instructions don't always coincide with the measurement markings on the syringe that comes with the liquid medication.
The warning letter, penned by scientists from Northwestern University Feinberg School of Medicine in Chicago, Emory University in Atlanta and Weill Cornell School of Medicine in New York City and published online Wednesday in the New England Journal of Medicine, also urges doctors and pharmacists to be on the lookout for this potential dosing mismatch and to help parents figure out exactly how much Tamiflu to give their child.
The authors cite a case that they say is probably happening all over the United States: The parents of a 6-year-old girl diagnosed with the H1N1 virus received a prescription for Tamiflu Oral Suspension that told them to give her three-fourths of a teaspoon of the medicine two times a day.

Steps Start to Add Up to a Math Path in the Brain
September 24, 2009
With functional MRIs, researchers see that numbers trigger distinct activity patterns. Careful observation and analysis of brain activity enables scientists to determine what number a person has just looked at or how many dots they've just been shown, a French study has found.
The researchers said their findings confirm the theory that numbers are encoded in the brain through detailed and specific activity patterns, something they say could help improve the investigation of humans' high-level numerical abilities.
While "number-tuned" neurons have been identified in monkeys, scientists previously had only been able to identify number-related brain regions in humans.

Cost Savings Adds to Value of Preventing Chronic Disease
September 23, 2009
Avoiding diabetes, high blood pressure can add years to life, researchers say. Prevention of chronic diseases such as diabetes, obesity and high blood pressure improves the lives of older Americans and also reduces medical costs, study findings show.
Researchers looked at a group of 51- and 52-year-olds from across the nation and projected their future state of health and medical costs if they could avoid developing certain chronic diseases. In a 51-year-old, prevention of obesity would extend life by 0.

Soap industry gives America a B-minus for hygiene habits. You're doing better, America, but with only a "B-minus" grade in hand-hygiene habits, you've still got a ways to go, an industry-sponsored survey finds.
This year's results are up from a "C-minus" last year, but the fifth annual "Clean Hands Report Card," distributed by the Soap and Detergent Association, still finds room for improvement.
The good news: 50 percent of the 888 respondents to the August telephone survey said they wash their hands more than 10 times per day.

Hand Washing 10 Times a Day May Help Keep Flu Away
September 23, 2009
Hygiene, masks, quarantines all work to halt spread of viruses, review finds. Medications, personal hygiene, mask-wearing and quarantines all help prevent the spread of viral infections such as the flu, and researchers now suggest that the latter three strategies should be given more attention in plans to deal with pandemics.
In an update of a 2007 study, Dr. Tom Jefferson of the Cochrane Acute Respiratory Infections Group in Rome, Italy, and colleagues reviewed the results of 59 studies that looked at the effectiveness of strategies to reduce the spread of viral germs that cause respiratory diseases such as the flu and SARS.

Hormone Therapy for Prostate Cancer Raises Heart Risks
September 22, 2009
Treatment methods should take into account side effects, researchers say. Hormone therapy to treat advanced prostate cancer can increase the risk of heart disease, but some types of hormone therapy appear to be safer than others, new research has found.
The study included 30,642 Swedish men with either locally advanced prostate cancer or prostate cancer that had spread (metastatic cancer), who had received hormone therapy as primary treatment for their cancer.
The study findings were scheduled to be presented Tuesday at the European Cancer Organization meeting in Berlin.

Easier detection method might encourage more people to get screened, experts say. Simple blood tests may someday become a noninvasive and cost-effective way to detect colon cancer, two new studies suggest.
Researchers were to present studies in Berlin, Germany, on Monday that could offer an alternative to colonoscopy or fecal occult blood tests for diagnosing colorectal cancer, the second leading cause of cancer death in the United States and Europe.
"We have found biomarkers that can be used to screen for colorectal cancer," said Dr.

Leukemia Cells May Hide in Fat Tissue
September 22, 2009
Finding explains why obese children have higher relapse rates, researchers say. Leukemia cells can hide in fat tissue to evade chemotherapy, which may explain why obese children with leukemia are more likely to develop chemotherapy resistance and have higher relapse rates, researchers say.
A previous study found that obese children with leukemia are 50 percent more likely to relapse than lean children.
In this new study, researchers observed that obese mice with leukemia had higher relapse rates than lean mice after they were treated with the first-line chemotherapy drug vincristine.

Goal is to prevent zoonotic infection rather than just track outbreaks, experts say. A better-coordinated global system is needed to improve prevention, detection and responses to outbreaks of infectious diseases that can be transmitted between animals and humans, according to a new report released Tuesday by the U.S. Institute of Medicine and the National Research Council.
Sex With New Partners Raises Widowers' Disease Risk
September 22, 2009
Erectile dysfunction drugs may have boosted seniors' sexually transmitted infection rates, researchers say. Older widowers who recently lost their wives are more likely to have a sexually transmitted disease than their counterparts who are still married, a new study has found.
The researchers behind the study add that drugs like Viagra could boost the risk, noting the widowers might be seduced by advertisements for sexual enhancement.
The risk that seniors have a sexually transmitted disease remains extremely low, at less than 1 percent, study co-author and Harvard researcher Kirsten Smith explained in a news release about the study.

Could Swine Flu Panic Be Worse Than Outbreak Itself?
September 22, 2009
With infections typically causing only mild illness, experts point to exaggerated fears as the real threat. With all the warnings and preparations, dire predictions and hastily ordered vaccines, could the growing worry about H1N1 swine flu prove more disruptive than the actual outbreak?
That notion is weighing on the minds of more than a few infectious-disease experts as the fall and winter flu season looms.
Not only does societal panic not help during a public health situation, such as the current H1N1 flu pandemic, it can actually backfire, creating its own set of problems, the experts said.

Flu Can Raise Chances of Heart Attack
September 22, 2009
Vaccine reduces risk of deaths related to heart disease, study shows. People suffering from the flu may be at higher risk for having a heart attack, especially those with heart disease and diabetes, British researchers report.
Because both seasonal and the pandemic H1N1 swine flu are circulating this fall and winter, people at risk for heart attacks are urged to get a seasonal flu shot and an H1N1 flu shot, which may reduce the chance of getting the flu and thereby lower the risk for a heart attack, experts say.
"Influenza is most concerning because of its secondary complications," said Dr.

Though operators largely follow the rules, the laws are too lax, study shows. Tanning bed operators appear to be largely abiding by parental consent laws, but the laws don't go far enough in limiting teens' exposure to harmful ultraviolet rays, a new study shows.
Tanning bed operators told data collectors posing as 15-year-old girls that as long as they had parental consent, they could tan as often as they wished, the researchers said.
That runs counter to a U.

Surgical patients more likely to finish radiation course, study finds. Incomplete and interrupted radiation treatment is a common problem among Medicare patients with head and neck cancer, a new study has found.
Researchers analyzed data from 5,086 Medicare patients diagnosed with head and neck cancer between 1997 and 2003 and found that nearly 40 percent of them experienced interruptions in radiation therapy or failed to complete the course of therapy.
People who had surgery before radiation treatment were more likely to complete the treatment without interruption than were those who did not have surgery (70 percent versus 52 percent).

Older Brains May Not Be So Small After All
September 21, 2009
Decrease in gray matter isn't a given, researchers find. Scientists have assumed that people's brains shrink as they age, but researchers now suspect that's not the case.
A study in the September issue of Neuropsychology examines long-term Dutch research into aging brains, which used neurological tests and MRI scans to measure parts of the brain.
The researchers looked at data from 1994 to 2005 for two groups: 35 people who were cognitively healthy and 30 people who did not have dementia but experienced cognitive decline during the time period.

New Chemo Regimen May Benefit Ovarian Cancer Patients
September 20, 2009
Dose-dense treatment improved survival, but too toxic for some: study. Dose-dense chemotherapy improves survival in women with advanced ovarian cancer, Japanese researchers say.
Currently, paclitaxel and carboplatin given every three weeks is considered standard first-line chemotherapy for advanced epithelial ovarian cancer. However, dose-dense weekly treatment with paclitaxel is seen as a way to increase progression-free and overall
survival in these patients, according to the new study findings.

Hormone Therapy May Make Lung Cancer More Likely
September 20, 2009
Expert says finding supports doubts about value of treatment. Taking a combination form of hormone replacement therapy, which includes both estrogen and progestin, increases a woman's risk for dying from lung cancer, a new study has found.
The finding stems from an analysis of data from the Women's Health Initiative trial on 16,608 postmenopausal women, aged 50 to 79, in the United States who had been randomly assigned to take either a once-daily tablet of 0.625 milligrams conjugated equine estrogen plus 2.

Middle-Age Heart Risk Factors Shorten Men's Lives
September 18, 2009
Smoking, hypertension, high cholesterol cut 10 years of life, study finds. Middle-aged men with risk factors for heart disease such as smoking, high blood pressure and high cholesterol are taking 10 to 15 years off their lives compared to men without these troubles, British researchers say.
Although death from heart disease has been declining, in part due to better control of cardiovascular risk factors and better care, this is the first study that looks at death from heart disease in terms of life expectancy, the researchers said.
"The good news is that all of us can make changes to live a healthy life," said lead researcher Dr.

Timing, Type of HRT May Determine Breast Cancer Risk
September 16, 2009
Starting estrogen-progestagen therapy early may up odds of disease, study shows. The timing and type of hormone replacement therapy women take to relieve menopausal symptoms seem to determine the degree of breast cancer risk they face, a new French study suggests.
Overall, starting estrogen-progestagen therapy soon after menopause appears to boost the risk of breast cancer, even when only used for short periods of time, according to the study, which was published in the Sept. 14 online issue of the Journal of Clinical Oncology.

Blacks Fare Worse After Cardiac Arrest
September 15, 2009
Poor hospital care a big reason why, researchers say. Black patients who suffer cardiac arrest in the hospital are much less likely to survive than white patients, a new study finds.
Most of this disparity appears to result from the hospital in which black patients receive care, although other factors play a role as well, the researchers said.
"We know that survival after having a cardiac arrest in the hospital setting has always been historically low," said lead researcher Dr.

Watchful Waiting Works for Older Men With Prostate Cancer
September 15, 2009
But experts stress the same does not hold true for patients under 60. Older men diagnosed with prostate cancer who choose watchful waiting are doing better these days than in the era before screening with a test for prostate-specific antigen (PSA) became common, a new study finds.
"The most important message is that the long-term outcome for patients who don't have surgery or radiation is pretty good," said study author Dr. Grace L.

Celiac Disease May Raise Risk of Dying
September 15, 2009
People with with mild form of the digestive disorder have slightly higher death rate, study shows People with milder symptoms of celiac disease face a slightly higher risk of dying than other people, a new study finds.
Cancer and heart disease were the main causes of death in the patients studied, and the risk was higher in people who had had small-intestinal biopsies in childhood, the researchers found.
Celiac disease affects about 1 percent of people in the Western world, the researchers said, and it is triggered by exposure to gluten, a protein found in barley, wheat and rye.

For Hispanics, a Unique Cancer Profile Emerges
September 15, 2009
Report finds they're less likely to die of cancer but more apt to have certain malignancies. Hispanics in the United States are less likely to die from cancer than non-Hispanic whites, but they have higher rates of cancers linked to infections, including stomach, liver and cervix malignancies, a new report says.
At first glance, Hispanics' lower death rate from cancer seems to be good news, but one explanation is that the Hispanic population skews younger than the general U.S.

Routine Testing Would Improve Herceptin Use in Breast Cancer
September 14, 2009
Targeted drug therapy often doesn't reach the right patients, study finds. New research suggests that the anti-breast cancer drug trastuzumab, also known as Herceptin, isn't reaching its full potential. Many patients aren't receiving tests that determine whether it's appropriate or are taking it when they don't need to.
Under current guidelines, women with breast cancer in its early stages should receive tests to see if Herceptin might be appropriate for them.

One Dose of Swine Flu Vaccine Offers Protection
Studies
September 11, 2009
Findings could expand vaccine supply and speed immunity, experts say. Preliminary tests of an H1N1 swine flu vaccine conducted in Australia and Britain show that a single dose creates enough antibodies to protect against the virus within about 10 days.
That's a potentially significant development, because it was thought that two shots would be needed to provide full immunity to the virus. A one-dose protocol would greatly expand the supply of vaccine and hasten individual immunity.

Deep Sea Microbes Shed Light on Human Biology
September 10, 2009
Scientists determine structure of enzymes involved in making ribosomes. By studying microbes that live near the boiling thermal vents of the deep sea, scientists have identified the structure of an RNA and protein enzyme that is key to making human ribosomes, new research shows.
Ribosomes, a component of all cells that have a nucleus, are responsible for translating the information encoded in DNA into proteins that are crucial for biological processes.
In their study, researchers from Yale University studied Methanocaldococcus jannaschii, a microbe considered an "extremophile" because it thrives in harsh conditions, including in Antarctic ice and at the bottom of the ocean.

Swine Flu Burrows Into Lungs
Study
September 10, 2009
Unlike seasonal flu, H1N1 goes deep into respiratory tract, researchers confirm. New British research confirms previous reports that the H1N1 swine flu goes deeper into the lungs than ordinary seasonal flu, possibly explaining why it's often more severe in some people.
"Most people infected with swine-origin flu in the current pandemic have experienced relatively mild symptoms," Ten Feizi, a professor at Imperial College London and co-author of a study released Thursday, said in a college news release. "However, some people have had more severe lung infections, which can be worse than those caused by seasonal flu.

Treating Childhood Leukemia With Fewer Side Effects
September 10, 2009
Dutch researchers skip radiation treatments, some chemo but add corticosteroid. Adding the corticosteroid dexamethasone to the treatment regimen of children with acute lymphoblastic leukemia improves survival rates and reduces the incidence of the cancer recurring, a new Dutch study shows.
Acute lymphoblastic leukemia (ALL), a cancer of the blood, is the most common childhood cancer and is highly treatable, according to background information in the study.
But the researchers say that many children with ALL are over-treated with cranial radiation and chemotherapy drugs that cause significant side effects and may not be necessary to cure them.

Chinese 'Devil Dung' Plant Could Be a Swine Flu Fighter
September 09, 2009
Extract used in 1918 pandemic may have antiviral properties, scientists say. A plant with a particularly malodorous sap has components that show great efficacy in killing off the H1N1 swine flu virus, Chinese scientists report.
The plant, Ferula assa-foetida, grows throughout Iran, Afghanistan and mainland China, and is commonly dubbed "Dung of the Devil" due to its ill-smelling sap. But the researchers note that the plant was used in China against the influenza virus during the great 1918 Spanish flu epidemic, which is thought to have killed tens of millions worldwide.

Antiviral Drugs Should Be Used Cautiously to Fight Flu, U.S. Says
September 08, 2009
Most people won't need medicines like Tamiflu or Relenza, according to CDC. Antiviral medications such as Tamiflu and Relenza, which are effective in treating the H1N1 swine flu, should be taken only by people hospitalized with the flu or those at high risk for complications from the disease, U.S. health officials said Tuesday.
Gene Linked to Liver Disease in Cystic Fibrosis
September 08, 2009
Screening for the variation could help identify risk factors early on, researchers say. A variant of a particular gene in people with cystic fibrosis greatly increases their chances of developing severe liver disease, new research shows.
Cystic fibrosis is an inherited disorder that can lead to deadly lung infections and digestive problems.
About 3 percent to 5 percent of the 30,000 people in the United States with the condition will also develop a serious form of liver disease, including cirrhosis and portal hypertension, or high blood pressure caused by obstruction in the liver, according to the Cystic Fibrosis Foundation.

Respirator Masks Best for Swine Flu Health Workers
September 03, 2009
Medical personnel should use them, but not the general public, experts say. Because people can catch the new H1N1 swine flu by inhaling the virus, health-care workers who deal with flu patients should wear properly fitted N95 disposable respirator masks, a new report from the Institute of Medicine advises.
These masks are not the same as loosely fitted surgical masks. N95 respirators fit tightly around the mouth and nose and have filters that can block about 95 percent of the flu virus, according to the report released Thursday.

Family, Friends Influence Breast Cancer Decisions
September 03, 2009
Patients' supporters often play role in treatment discussions, study finds. Family and friends don't just serve as emotional support for breast cancer patients, they also help patients decide which kind of surgery to have, a new study has found.
About three-quarters of patients surveyed brought a family member or friend to their first appointment with a surgeon, and the accompanying person exerted influence on the patient, the University of Michigan researchers noted.
In particular, women who had a friend or family member accompany them to the first appointment were more likely to receive a mastectomy, compared with women who went alone.

September 01, 2009
Researchers challenge 'superbug theory' in animal tests using three flu strains. Fears that the H1N1 swine flu will turn into a "superbug" this year may be unfounded, say researchers at the University of Maryland.
In laboratory tests, the virus responsible for the swine flu pandemic did not take a virulent turn when combined with other strains of seasonal flu. But it did spread more rapidly than the other viruses, confirming the need for swine flu vaccinations, the researchers said.

Blood Test May Spot Pancreatic Cancer Early
September 01, 2009
Researchers hope to detect the disease while it is still treatable. Texas scientists say they have found small molecules in the blood that can spot pancreatic cancer, a finding that could have diagnostic implications in the future.
Levels of these molecules, called microRNAs, are elevated in patients suffering from pancreatic cancer, the fourth-leading cancer killer in the United States. The disease usually isn't diagnosed until it is in an advanced stage, when treatment is all but ineffective, the researchers say.

Adult Weight Gain Tied to Prostate Cancer Risk
September 01, 2009
White men risk more aggressive tumors if pounds mount up in 20s, 30s, study finds. Men who pack on excess pounds as young adults are at heightened risk of developing prostate cancer, although the risk varies by ethnic group, researchers from the University of Hawaii report.
Obesity is a risk factor for many common cancers, including colorectal cancer and breast cancer in postmenopausal women. However, whether obesity plays a role in prostate cancer risk has been unclear, researchers say.

New Therapy Spares Organ in Early Esophageal Cancer
September 01, 2009
Less invasive procedure shaves off lesions, preserves esophagus, researchers say. Early-stage cancers of the esophagus can be treated effectively by less invasive, organ-sparing endoscopic therapy, a new study has found.
This is good news, as esophageal cancer arising from Barrett's esophagus is increasing in frequency faster than any other cancer in the United States, and 90 percent of patients die within five years of being diagnosed, according to a news release from the Mayo Clinic.
Esophageal cancer is diagnosed in its early stages about 20 percent of the time, Dr.

Blood Thinner May Prevent Chemo-Related Clots
September 01, 2009
Daily injection cut risk in half for Italian study patients. Cancer patients who receive chemotherapy are more likely to develop blood clots than other people, but now a new study says a blood-thinning drug could cut the risk in half.
Besides posing a significant risk of problems in the heart, brain and lungs, blood clots are especially difficult to treat in cancer patients and can lead to interruptions in chemotherapy. They can also greatly increase costs in patients who already face high expenses, the researchers noted in their study published online Aug.

Chemotherapy Linked to Sleep-Wake Cycle Disruptions
September 01, 2009
Biological clock out of sync in patients being treated for breast cancer, study finds. New research suggests that chemotherapy in breast cancer patients disrupts cycles of sleep and wakefulness, and continued treatment leads to worse and more lasting problems.
In the study, researchers recruited 95 women with breast cancer who were scheduled to receive chemotherapy. Their average age was 51.

Prostate Cancer Over-Diagnosed
Study
September 01, 2009
The result is over-treatment for many men, researchers say. Mass screening for prostate cancer with a test for prostate-specific antigen (PSA) has led to mass over-diagnosis and over-treatment, a new study contends.
Since the PSA screening test came into use in 1986, federal government data show that the number of prostate cancer cases in the United States has risen substantially, said the report in the Aug. 31 online issue of the Journal of the National Cancer Institute.

Exposure to Tobacco Smoke Before Birth Affects DNA
August 31, 2009
Cigarettes may trigger prenatal gene changes, leading to lifelong health problems, study suggests. Women who smoke while pregnant increase their unborn child's long-term risk for health problems, including childhood asthma, cardiovascular disease and lower pulmonary function, and a new study may help experts understand why.
Researchers at the Keck School of Medicine of the University of Southern California (USC) found that maternal smoking actually changes the unborn child's DNA patterns.
The new study found that fetal exposure to maternal smoking was linked to differences in DNA methylation, an epigenetic mechanism.

New Robotic Arm Has Softer Surgical Touch
August 31, 2009
Device helps find tumors during minimally invasive surgery, researchers say. A robotic surgical arm that can gently "feel" for cancerous tumors during minimally invasive surgery has been developed by Canadian scientists.
The device, invented at the University of Western Ontario and at Canadian Surgical Technologies and Advanced Robotics, will help surgeons better isolate tumors from softer surrounding tissue and, it is hoped, improve cancer survival rates, according to the study published in the September issue of the International Journal of Robotics Research.
During an operation, surgeons often use their hands to palpate (or gently feel) for tumors, which tend to have a different texture from healthy tissue and can shift in the body after a CT scan and other pre-surgical imaging tests.

Meat, Dairy Won't Up Odds for Breast Cancer
August 28, 2009
Two studies find no clear link; other research supports fiber to ward off the disease. An adult woman's intake of meat, eggs and dairy products should not boost her risk for breast cancer, new research shows.
For years, dietary factors have been debated as either boosting or reducing the risk of breast cancer, with research yielding conflicting results. But in the new research, scientists could not conclude that meat, eggs or dairy product intake as an adult raised breast cancer risk.

Tobacco Use Kills 6 Million People Annually
Report
August 25, 2009
And costs the global economy $500 billion each year. Tobacco use kills an estimated six million people worldwide each year and drains $500 billion annually from the global economy in lost productivity, misused resources, and premature deaths.
That assessment comes from The Tobacco Atlas, Third Edition, published by the American Cancer Society and the World Lung Foundation and released Tuesday at the LIVESTRONG Global Cancer Summit in Dublin, Ireland.
What's more, illnesses and deaths from tobacco use are totally preventable through such "well-established public policies" as tobacco taxes, advertising bans, smoke-free public places, and health warnings on packages, the report said.

More Women Surviving After Early Breast Cancer
August 25, 2009
Still too little is known about these 'in situ' malignancies, experts say. The first accounting of women with breast cancer in situ in the United States finds that in 2005 there were 610,171 survivors, but that by 2016 that number is expected to increase to more than 1 million.
Breast cancer in situ now accounts for 20 percent of newly diagnosed breast cancers. It is the early stage of the disease, when it is still confined to the layer of cells in the ducts or lobules of the breasts.

HPV Vaccine Could Prevent Many Penile Cancers
August 25, 2009
Nearly half of the tumors are caused by strains covered by the shot, study finds. The human papillomavirus (HPV) causes about half of penile cancer cases in the world, and giving vaccines to males could greatly reduce the incidence of the disease, a new study suggests.
Penile cancer remains rare, accounting for less than 1 percent of adult male cancers in North America and Europe, but that rate jumps to as high as 10 percent in Africa and Asia, according to Spanish researchers reporting online Aug. 25 in the Journal of Clinical Pathology.

Hormone Therapy for Early Prostate Cancer Not Always Best
August 25, 2009
Study finds treatment raises death risk in those who also have heart disease. Men who have been diagnosed with prostate cancer and who also have underlying heart disease may not benefit from treatment with hormones, new research suggests.
In fact, such hormone therapy may actually increase their odds of dying.
"For men who've had a prior heart attack or heart failure, use of hormone therapy for prostate cancer was associated with a shortened lifespan," said study author Dr.

Tamoxifen May Up Risk of Second, More Aggressive Breast Cancer
August 25, 2009
But survivors shouldn't stop taking the anti-cancer drug, experts say. The drug tamoxifen is a tried-and-true way to lower the chances of developing the most common type of recurrence among breast cancer survivors, but new research suggests it raises the risk of getting a more aggressive cancer in the healthy breast by more than four times.
However, the finding is no reason to ditch the anti-cancer drug, as even the lead researcher emphasized.
"All treatments have risks and benefits," said study author Dr.

Protein May Identify Deadlier Breast Cancer
August 25, 2009
Findings might help doctors determine prognosis, researchers say. A protein linked to more aggressive and advanced breast cancer tumors has been identified by German researchers.
The investigators analyzed 229 breast tissue samples from patients with cancer and compared them with healthy breast tissue. The study found that patients whose tumors had elevated levels of GLI1 (glioma-associated oncogene homolog 1) protein tended to have a more advanced stage of cancer, had an increased number of cancerous lymph nodes and a greater chance of death.

Medication Review May Help With Heart Failure
August 21, 2009
Hospitalizations decline when doctors, pharmacists collaborate, study finds. If doctors and pharmacists work together to ensure that people with heart failure take their medicines correctly, hospitalizations would be less frequent, an Australian study suggests.
In a study of 5,717 people with heart failure, the hospitalization rate for the 273 who had their medications reviewed by doctors and pharmacists was 45 percent lower than the hospitalization rate for the others, whose medicines did not undergo a collaborative review.
People in the study averaged about 82 years old.

Finding supports worthiness of genetic screening. People with lung cancer who are screened for a genetic mutation and then given a drug called Tarceva, which is believed to work well with that mutation, live longer than those without the mutation who take the drug, new research has found.
According to the Spanish authors of a study in the Aug. 20 issue of the New England Journal of Medicine, this type of widespread screening is actually doable and could lead to better decisions about treatment.

Newer Drug Beats Tamoxifen for Older Breast Cancer Patients
August 19, 2009
Letrozole boosted survival and should be first-line treatment, experts say. For postmenopausal women with breast cancer, treatment with the drug letrozole (Femara) increases survival after surgery more than the widely used tamoxifen, a new study confirms.
Both letrozole and tamoxifen have been used to prevent recurrence of breast cancer in postmenopausal women with hormone receptor-positive cancer, but whether one drug is better than the other has been unclear. The new study compared the impact of the newer drug, letrozole, to tamoxifen.

Blood Pressure Drug Might Work Against MS
August 17, 2009
Research shows inflammation link between two disorders. Dr. Lawrence Steinman has this seemingly crazy idea that a drug commonly used to combat high blood pressure can help prevent the damage done to nerve cells in multiple sclerosis.
But people in the know tend to listen carefully to the ideas of Steinman, a professor of neurology at Stanford University, because one of his ideas was crucial in the development of natalizumab (Tysabri), a now widely used medication that can reduce the incidence of relapses in multiple sclerosis (MS) by two-thirds.

Chewing Tobacco No Safer Than Smoking
August 17, 2009
New study adds to list of carcinogens harming those with smokeless habit. Tobacco users who think it's safer to dip snuff or chew tobacco than smoke are dead wrong, researchers say.
A study has found that taking one pinch of smokeless tobacco delivers the same amount of polycyclic aromatic hydrocarbons (PAHs) as smoking five cigarettes.
PAHs are common environmental contaminants that are formed as a result of incomplete burning of wood, coal, fatty meat or organic matter, according to information in a news release from the American Chemical Society.

Sex Hormone Levels Linked to Fractures in Men
August 14, 2009
Testing for estradiol, testosterone and SHBG could predict those at risk, expert says. Sex hormone levels affect the risk of broken bones in older men, says a new study.
The finding comes from a study that included 1,436 men age 65 and older who had their sex hormone levels measured periodically for about five years. The researchers found that men with low levels of estradiol or high levels of sex hormone binding globulin (SHBG) were more likely to suffer osteoporotic fractures.

Wine May Shield Breast Cancer Patients From Radiation Side Effects
August 14, 2009
Italian study suggests its natural antioxidants protect the skin. A glass of wine a day cut the risk of treatment-linked skin toxicity by two-thirds in women undergoing radiation therapy for breast cancer, Italian researchers report.
Skin reactions are a common side effect of cancer radiation therapy, and, while medications can help prevent these problems, they can be expensive and often have their own side effects. In some cases, drugs used to reduce radiation-linked side effects can actually protect breast cancer tumor cells, according to a news release from the American Society for Radiation Oncology.

Get Smart About Swine Flu for Back-to-School
August 14, 2009
Simple steps can minimize the risk as fall looms, experts say. Students returning to school this year have another worry besides homework and lunchroom bullies: swine flu.
Experts say parents and kids need to act early and vigorously to reduce their risk of contracting the H1N1 virus.
"We do know that [the virus] is going to strike the school-age child and it's primarily because they're in crowded classrooms with lots of other children and have a better chance of spreading germs," said Sharon A.

Compound Targets, Destroys Cancer Stem Cells in Mice
August 13, 2009
Therapeutic possibilities are uncertain, researchers say. Researchers have identified a chemical able to seek out and destroy the stem cells that scientists believe give rise to cancer recurrence after treatment.
A growing body of research is showing that cancer stem cells play a role in cancer metastasis and in causing cancer to reappear even after treatment seems to have eradicated the initial tumor.
"Evidence is accumulating rapidly that cancer stem cells are responsible for the aggressive powers of many tumors," including breast, prostate, lung and others, said study author Robert Weinberg, a member of the Whitehead Institute for Biomedical Research at Massachusetts Institute of Technology.

MRI May Not Improve Breast Cancer Outcome
August 13, 2009
But it does increase likelihood of extensive surgery, researchers say. The use of MRI before surgery to assess the extent of early breast cancer may do more harm than good, a new review shows.
The study authors said this use of MRI increases the likelihood that patients will have more extensive surgery instead of a conservative therapy, but that this more aggressive treatment doesn't lead to improved surgical care or patient outcomes.
"Overall, there is growing evidence that MRI does not improve surgical care, and it could be argued that it has a potentially harmful effect," wrote the American and Australian researchers.

Cancer Deaths Declining, Especially Among Young
August 13, 2009
Advances in treatment, prevention and detection behind progress, study finds Cancer death rates are declining, especially among younger people, new research shows.
And while cancer is poised to become the number one killer in the United States, topping heart disease, that is because deaths from heart disease have decreased faster than for cancer.
"Older Americans have only experienced decreased [cancer] mortality very recently, but younger Americans have been seeing benefits for a long time so, as a result, everyone born in the last 60 years has been reaping the benefits of efforts in prevention research and treatment research and early detection research," said Dr.

When It Comes to Casual Sex, Men Aren't So Picky
August 12, 2009
Women place greater emphasis on good looks, study finds. Men are much more likely to seek and have casual sex than women, and are far less choosy about the looks of their sex partners.
That's the conclusion of a new study by British researchers who analyzed questionnaire responses from 860 American, German and Italian students.
The students were asked to imagine being approached by a member of the opposite sex, described as either "slightly unattractive," "moderately attractive" or "exceptionally attractive.

New Antibiotics May Target Cancer-Causing Proteins
August 12, 2009
Anti-cancer use of thiazoles could be possible, research suggests. Scientists are closer to understanding how a recently approved class of antibiotics may work against cancer.
The drugs, called thiazole antibiotics, appear to block a cellular protein called FoxM1, one of the most over-produced proteins in cancer cells, according to researchers at the University of Illinois at Chicago College of Medicine. FoxM1 is believed to play an important role in causing cells to become cancerous and may present a promising target for future anti-cancer treatments.
