According to the survey in HealthDay News, February 27 indicates that more vitamin D than was initially thought to dramatically reduce the risk of several serious diseases, including breast cancer.

“We found that adults need to consume daily between 4,000 and 8,000 IU to maintain blood levels of vitamin D metabolites in the range needed to reduce the risk of several diseases such as breast cancer, colon cancer, multiple sclerosis and diabetes type 1, half, “said study co-author Dr. Cedric Garland, professor of family and preventive medicine at the University of California at San Diego, in a news release from the university.

Garland admitted he was surprised that the required levels were much higher than the 400 IU per day necessary to overcome rickets in the twentieth century.

Vitamin D supplements often come in pills or capsules containing between 1,000 and 2,000 international units. But taking between 4,000 and 8,000 IU a day is still much lower than the range considered safe by the National Academy of Sciences Institute of Medicine, the researchers said.

The study, which also involved the Faculty of Medicine at Creighton University in Omaha, was based on a survey of several thousand people who took supplements ranging from 1.000 to 10.000 IU per day. The volunteers also underwent blood tests to determine levels of metabolites of vitamin D circulating in the blood.

Some studies suggest that only 10 percent of the U.S. population has the appropriate level as related to vitamin D in the blood that prevents the disease associated with a deficiency of this vitamin. They tend to work outside, so their vitamin D levels increase with sun exposure.

Last year, a committee of the National Academy of Sciences and the Institute of Medicine (IOM) announced to take 4.000 IU per day of vitamin D seems safe for adults and children ages 9 and older.

However, the daily minimum recommended by the IOM is 600 IU; the Institute also noted that there were early signs that there could be some damage associated with consuming high levels of vitamin D a day, even in amounts below the recommended upper limit as insurance.

Garland and his colleagues suggested that 4,000 IU a day is a safe level.

“Now that we have the results of this study, taking 4000 IU per day will become commonplace for most adults,” Garland predicted in the press release. “This is below the 10,000 IU per day that the IOM Committee Report considered as the lower limit of risk, and the benefits are substantial.”

One of the biggest disadvantages of cancer is due to its wide variety of types becomes very difficult to detect and cure. However, scientists and researchers related to the medical field are still struggling to develop drugs that prevent the development of the disease.

Among the most advanced is the multiple myeloma, a cancer that attacks the blood and has a high mortality rate. For this type of disease has developed a vaccine that can recognize the appearance of mutated cells to eliminate and prevent subsequent development of cancer.

The method has been tested with good results and would be especially helpful for patients who are more likely to suffer from multiple myeloma because their bone marrow contains a high number of plasma cells. It’s clearly a breakthrough for a disease that is still classified as “incurable.”

According to an article published in the journal Science Translational Medicine, and the new system used by doctors managed to succeed in the diagnosis of cancer in 96 percent of patients, a figure higher than with the traditional biopsy. Doctors at Massachusetts General Hospital, equipped with a mobile phone, a thin needle and a small molecular magnetic resonance apparatus, have been detected in simple and effective cancer tumors.

According to César M. Castro, of Harvard Medical School, Boston, and a member of the team that developed the procedure: “The system prevents patients undergo procedures that are painful and potentially dangerous.”

The standard method for diagnosing cancer is the collection of a portion of tumor tissue, which is subjected to immunohistochemistry, the name given to the test in which a specific antibody is used to “mark” the existence of cancer cells. The acquisition of this tissue samples and sometimes requires surgical biopsies and the results can take three or more days.

Rapid molecular analysis developed in Massachusetts also requires collecting a cell sample, but is removed with a thin needle (0.7 mm in diameter) in a traditional biopsy (1.4 mm in diameter). Moreover, there is waiting time, which “reduces the time of patient anxiety due to the rapid achievement of an outcome, usually in less than an hour,” said Castro.

The team consists of a cell phone “smart” common and apparatus cylindrical nuclear magnetic resonance measuring five centimeters in diameter. The researchers tested the method with 50 patients with suspected abdominal tumor and biopsies had been ordered routine.

At the same patients after samples were taken using the needles commonly used for biopsies and samples were sent to the conventional method of diagnosis. Instead of the tissue samples required by the conventional method, this system can work with the small number of cells by fine-needle aspirates.

The nuclear magnetic resonance microaparato magnetic nanoparticles used as sensors that measure the chemicals in the cells and the device is connected to a telephone so that doctors can measure and read the data with the patient’s bedside.

After scanning the tissues from patients to detect the expression of nine key proteins, physicians correctly identified 44 patients who had malignant tumors, and each of the diagnoses were confirmed with conventional biopsy.

The identification rate of cancerous tumors with this technique exceeds 84 percent with immunohistochemistry. According to Castro: “These protein markers can indicate the likelihood that cancer grow and spread to other tissues in the body.”

People and Society the Journal News on the web, I realize a publication concerning the great controversy between the connection between cellphones and cancer. Years of studies have generated results found. But there is no consensus on the degree of cancer risk posed by the use of cell phones.

The main concern seems to be the development of brain tumors associated with the use of mobile phones. Some studies suggest a slight increase in the rate of brain tumors from the 70, but these subtle increases may be related to other factors, such as greater access to the medical system and improvements in diagnostic imaging, and a slight real increase in lymphomas brain due in part to HIV and other diseases affecting the immune system. In fact, it would be impossible for the cell is the cause of increased brain tumors in 70 because in those years were not used.

So what researchers found out about cell phones and cancer? In a recent study that followed more than 420,000 users over a period of 20 years found no evidence that there is a connection between brain tumor cells. Another recent study suggested an association between cancer cells and salivary glands.

However, only a small number of participants had malignant tumors had a clear increase in the use of snuff – known cause of salivary gland cancer – between the partners.

However, a number of recent studies cannot tell the whole story. Sometimes it takes many years between the use of a new cancer-inducing agent-like snuff – and the observation of increased cancer rates. At this point, you may have spent too little time to detect an increase in cancer rates directly attributable to the use of cell phones.

How short? For now, nobody knows if the phones are capable of causing cancer. Although long-term studies are ongoing, to date no convincing evidence that any risk of cancer. For those concerned, the advice is to limit the use or use a headset to place the antenna away from the body cell.

The British Medical Journal (BMJ) published a study online which state that dogs can detect bowel cancer by smell with a high degree of accuracy even though the disease is in its initial phase.

Apparently, the authors of that study indicated that there are chemical compounds for specific types of cancer circulating in the human body and a dog can smell. This, according to a team of experts from the Department of Surgery, Kyushu University, Japan, the possibility of developing tests to detect the disease before it may have spread to other parts of the body.

To reach these findings, conducted an experiment with a specially trained Labrador, which made for some months between the smell test that included breath test and stool samples of participants.

The samples belonged to 48 people diagnosed with bowel cancer and 258 volunteers without the disease or had had cancer in the past.

About half of the samples of volunteers came from people with bowel polyps, although benign, are considered precursors of bowel cancer.

6 percent of the breath test and one in ten of the stool samples of this group came from people living with other intestinal problems such as inflammatory bowel disease, ulcers, diverticulitis and appendicitis.

The bowel cancer was obtained from patients suffering from various levels of the disease, which included the early stages.

The dog successfully identified which were cancerous and which are not, in 33 of 36 urea breathe test in 37 of 38 stool test, with the highest rates of screening among those taken from people who had the disease at an early stage.

This amounts, according to the study, 95 percent accuracy, in general, for samples of breath and 98 percent in the case of stool, compared with the results of conventional colonoscopy.

Experts noted that in the case of samples of smokers or people with other problems, in which one might think that these factors interfere with or would mask other odors, did not raise any problem for the dog.

The study showed that there are discernible specific odors arising from cancer cells circulating in the body, a theory supported by other research indicating that dogs can sniff out bladder cancer, skin, lung, breast and ovary.

The authors admit that use dogs to detect cancer are probably impractical and expensive, but added that from this finding could develop a sensor to detect specific components.

Obesity is the major nutritional diseases that exist today. The biggest problem this condition is causing malnutrition and indiscriminate intake of foods high in fat and sugar. The highest levels of obesity seen in most developed countries, with the United States led the rankings due in large part on how the intake of junk food.

Obesity brings not only aesthetic, but also various digestive ailments, diseases linked to cancer in the esophagus, rectum, pancreas, and intestines. In addition, other heart diseases (such as clogged arteries) and chronic hepatitis are major problems linked to obesity.

This disease is becoming more frequent and it generates lots of concerns, especially because it is down significantly the age of people suffering from obesity. Children are becoming more prone to disease, especially due to the distortion of eating habits.

Best to combat this disease is to make a medical appointment quickly when you see the very significant weight gain compared to normal weight. Be very careful because the consequences of obesity are very complicated to treat.

For children we recommend a visit to the doctor and provide psychological support along with a balanced diet with physical activity. This can prevent many more serious problems to health.

The British Medical Journal (BMJ) published a report stating that one in three breast cancer cases would be over diagnosed. Overdiagnosed refers to the fact that the anomalies presented never provoke discomfort, symptoms and much less death.

In this regard, we note that it may be giving unnecessary treatment to women who do not need and could be wasting efforts that would be better spent on real cases that need urgent treatment.

Every year one million new cases detected breast cancer in the world. This is the most common cancer in women and that each year kills 400 000 patients.

Urges early detection of this disease and therefore it is recommended to women who are examined and periodically. Especially in the passing of 50 years. Breast cancer is curable if detected early. Several countries have implemented programs for older women to have carried out tests from time to time discard. It is also recommended that doctors do not order biopsies only with mammogram results. It is better to be sure it is really necessary.

Nature Cell Biology has published a study by the University of Tsukuba in Japan in which states have discovered an enzyme capable of preventing breast cancer metastasis.

The SRC-3 gene regulatory enzyme present in CHIP can prevent breast cancer spreading to other organs. Thus, this catalyst stops the spread of cancer and prevents other areas being affected

The test consisted of Tsukuba University in the administration of this enzyme in mice and the results were that his presence would stop the spread of cancer and encouraged his absence.

As we know the mortality caused by breast cancer is mainly because it spreads through the rest of the body without control. But with this discovery could be facing a new beginning in the treatment of this disease.

Are detected each year one million new cases of women with breast cancer and 400 000 die at the same time because of this evil.

the technology is constantly and not only in the field of entertainment, but also for science and health. Medical treatments are increasingly comprehensive and complex, which can raise the quality of life at an unexpected rate for 25 or 30 years.

Patients suffering from breast cancer are those who will benefit most from the technological improvements, especially in the field of molecular microbiology. According to a recent interview with Dr. Lourdes Calvo Spanish graphic by half within a short time you can start eliminating surgery as the primary option for treating breast cancer.

The main idea of this research is to achieve methods of treatment and cure for cancer diseases safer and more effective. For this reason studies are focusing on the development of individualized treatments, ie healing methods will be similar but in turn will differ from patient to patient.

In addition, Dr. Calvo said that soon a biopsy and genomic treatment will be more than enough for clinicians to know what kind of cancer they are dealing, in order to develop a specialized treatment, individual, and that allows patients to lead a normal life without suffering the side effects of chemotherapy or other similar practices.

Held in suspicion by much of the medical profession, homeopathy is a quiet entrance to the hospital, where doctors prescribe it as an adjunct treatment for cancer as heavy on the base to the most skeptical of his Under supposed magical placebo.

Homeopathy

Given the enthusiasm of patients, practitioners have done so in several hospitals in France, as in Lyon, central fight against cancer Léon Bérard.

Among them, Thomas Bachelot oncologist who, while defining itself as a “skeptical of Homeopathy,” uses these drugs to relieve the side effects of chemotherapy and radiotherapy such as nausea.

“Homeopathy is a good therapeutic approach, a smart way to care for patients: it works because people like to be listening,” he says.

“I tell patients that I do not see how it works from a scientific perspective. For me it is very poetic, without rational basis. But it works because people like magic, “he adds.

With colleagues, he nevertheless embarked on studies to try to assess the impact of homeopathic substances, beyond the placebo effect.

Conducted with hundreds of patients, these studies, financed by the Boiron homeopathic laboratory conducted independently but ensures the establishment of reference, have had mixed results.

Calendula cream and has proved more effective than conventional Biafine used to relieve skin burns with consecutive radiotherapy.

Another study on Cocculine, noted a significant decrease nausea. Only problem, even if the decline is troubling: it is the same in patients taking placebo and homeopathic tablets.

Enough to feed the arguments of critics of homeopathy, whereby its main feature (or dilute mineral plants in the extreme) would be a scam.

Located near Lyon, Boiron, world leader in homeopathic medicine, deplores this skepticism within the scientific community.

According Boiron, practitioners prescribing homeopathic medicines (including over 10,000 are reimbursed by Social Security) number in the thousands now in France, while the formations have multiplied, including within the faculties of medicine and pharmacy.

“Homeopathy is becoming commonplace, with patients coming to a homeopathy consultation as they go to the psychologist or dietician. But the homeopathic consultation is marginal in hospital, “says Marie-France Bordet, homeopathic doctor at the hospital in the Red Cross, and also employed by Boiron.

In the service of this great Hepatology CHU Lyon, it essentially follows patients with hepatitis C, suffering from side effects of their treatments as skin problems or coughs.

Originally its consultation is the will of a head of service “offering homeopathy at home, in hospital, performed by real doctors, so that patients suffering from ending up victims charlatans.

“Homeopathy is a therapeutic method, not a medicine in itself. If a patient needs antibiotics or steroids, I prescribe him! “She says, far from the caricature of the homeopath castigating vaccines as antibiotics.
