Vital signs: screening: mammography seen ineffective in Europe


An analysis of data from six European countries suggests that mammography had screening has no effect on breast cancer -Mortalität.



Deaths from breast cancer significantly industrialized to countries in most declined, but it is difficult to know how much of the decline due to early detection, treatment or the efficiency of health systems.


Researchers used a natural experiment in three pairs of countries. Some, initiated regular mammography screening much earlier than others, but their health systems and socio-economic levels were nearly identical. The countries that for the comparison were paired in Northern Ireland and the Republic of Ireland; the Netherlands and Belgium; and Sweden and Norway.


The study, published in the British medical journal BMJ, found online July 28, that in all three cases, previous implementation of screening had no effect on mortality. For example, in Northern Ireland, screening was introduced in the early 1990s, and 75 percent of the women got 1995, mammography. In the Republic of Ireland screening was introduced until 2000, and it was not until 2008 that showed 76% of the population. From 1989 to 2006, breast cancer mortality were 29.6 percent in Northern Ireland and by 26.7 per cent in Ireland.


"We were surprised and very sad to find that breast cancer screening does not work," said Dr. Philippe Autier, lead author. "We had expected to find the opposite."

Vital signs: nutrition: stealthy vegetables: getting children to eat more

Good news for parents: can your kids, Zucchini, tomatoes, broccoli, cauliflower and squash eat - and how they.

Researchers at the replaced these vegetables, pureed, kids meals, every meal calorie reduce Penn State but just to maintain their weight. One day a week for three weeks 40 children were given regular meals, meals with three times as much vegetables content or meals with four times as much vegetables content randomly. The children were eating told as much or as little as they wanted to.

The same amount of food by weight placed on the 3 - to 6 - year-old, participants in a day care center, regardless of whether the pureed meals contain vegetables. But those who ate meals with quadrupled vegetable content increase their vegetables total intake of 73 grams and reduce their calorie intake by around 12 per cent during the study.

Asked the taste as yucky rate OK or tasty, more than 70 percent of children assessed the vegetables falsified meals as OK or tasty. The study was published online July 20 in the American Journal of clinical nutrition.

"The controversial aspect is that it is deceptive," Maureen k. said spill, lead author and researcher at Penn State. "But it's just another way, to make recipes healthier." "It is still important for children to learn how vegetables look and taste how get."

Vital signs: risks: women's cancer risk increases with height, study

A woman is ever greater, your risk for canceris the greater, a large-scale study.

Researchers at the University of Oxford in England analyzed data on more than 1.2 million British women for an average 9.4 years followed. There were more than 97,000 cases of cancer among women. The researchers found that for every four-inch increase in the height of more than 5 feet 1 inch, the risk that a woman by around 16 per cent increase would cancer. The study was published online July 21 in the Lancet Oncology.

The analysis covers the 17 types of cancer, but the relative risk increase is statistically significant for only 10 of them. The authors suggest that levels of growth hormone on the development of cancer could be involved in or higher people are simply vulnerable to mutations because their bodies include more cells.

The authors reviewed previous studies showing that a similar connection between height and an increased risk of cancer in Asia, Australasia, Europe and North America has been observed.

"There is interest in this study he us a clue about how cancer could develop,", said Jane Green, the lead author and an epidemiologist at Oxford. "It is the similarity to many different types of cancer in people with many different risk factors, and in many different populations, which makes us think that it is something very important in the development of cancer."

Vital signs: hazards: tobacco smoke can affect hearing


The long list of the harmful effects of tobacco smoke to add yet another element: hearing loss in teens.



Researchers, writing in the July issue of the archives of Otolaryngology - Head and neck surgery, an indicator of exposure to tobacco smoke and cotinine more than 2,000 young people tested. After the removal of smokers from the trial, they remained the cotinine levels 799 non smoking exposure to tobacco smoke, with 754 display that were exposed to not smoke.


Of control many variables they, found that the higher the cotinine level in the blood of the person the greater the likelihood that it was some type of hearing loss. More than 17% in the, highest quartile for cotinine levels had hearing loss at low frequencies.


It is not clear, just as exposure to tobacco smoke could cause the damage, but tobacco is known that the smallest blood vessels affect blood flow, the type depends on the inner ear


"Most of the children, about 85 percent, their hearing loss, were not aware," said Dr. Anil k. Lalwani, the main author of the study. "You can rely on self reports."

Vital signs: exercise: frontiers in the heart of screenings for young people


Screening young athletes with Electrocardiograms for the prevention of sudden cardiac death ineffective, may be a new study has found. It turns out, also Pediatric cardiologists often not the tests correctly interpret.



Researchers at Stanford University selected underlying 18 ECG, 8 anomalies of patients with normal heart and 10 patients with one of the six different, the often sudden cardiac death. The scientists showed the ECG to 53 experienced paediatric cardiologists, whether she could make the right diagnosis properly restrict or allow sports activity and order appropriate follow-up audits. The correct diagnosis and recommendations based on the report by two Electrophysiologists, cardiologists specialized in the interpretation of the ECG.


Properly, only 68 percent of really abnormal cases identified the cardiologist - 32 per cent of young people with abnormal ECG were never found. And the cases that identify doctors as abnormal, 30 percent were in fact normal.


"One of the most remarkable discoveries was the inability of the cardiologists give correct sport," said Dr. Anne M. Dubin, Associate Professor of Pediatrics at Stanford University and author of the new study lead. Should be 26 percent of patients who were allowed to exercise were not, and 19 percent of patients who should have restricted were not, she noticed.


The report appeared of Pediatrics online on Thursday in the journal. Dr. Dubin received scholarship support from Medtronic Inc., a manufacturer of medical equipment.
