The study, led by Pauline Maki, professor of psychiatry and psychology at the University of Illinois, is the largest conducted on the effects of hormone therapy and involved 180 women aged 45 to 55 years who had their last period of one to three years earlier.

These women were given, randomized, placebo or hormone therapy consisting of a daily dose of estrogen and progesterone for four months.

Also made in these studies of memory, attention, cognitive function, emotional status, sexuality and sleep.

“If women want relief from hot flashes and night perspiration, which is the primary reason why women seek treatment during menopause, and if you want to improve their sexual interest and attention, then that combination may be the formula for them” said Maki.

The study did not identify significant changes in cognitive function that were different between women receiving hormone and those receiving placebo.

But women taking hormones reported an 32 percent increase in sexual thoughts and a 44 percent increase in sexual interest compared with women taking placebo.

The study also showed that women with vasomotor symptoms such as hot flashes and night perspiration, showed a reduction in symptoms and improved quality of life during therapy, which did not happen with those receiving placebo

20 percent of primary brain cancer is glioblastoma multiforme, a type of tumor survives only 5 percent of patients five years after diagnosis.

Scientists wanted to use the immune system to destroy brain cancer cells had to face two challenges: to recruit defensive cells that recognize the tumor antigen, called dendritic cells from bone marrow and help them to recognize tumor cells.

Now a team of researchers from Cedars Sinai Medical Center in Los Angeles, reports the journal Public Library of Science Medicine, has successfully achieved both objectives through a combination of genetic and chemical therapy.

The scientists were able to activate dendritic cells and stimulate a strong antitumor immune system, which resulted in a regression of cancer, increased survival of animals and the induction of immunological memory against cancer.

Speaking to EFE, the head of research, Argentina María G. Castro explained that the first step in the complex process involved injecting two therapeutic virus within the tumor mass, resulting in a double reply of immune system activation.

One of the virus, which causes cancer manufactures a protein type cytokine, attracted dendritic cells that migrated through the bloodstream from the bone marrow.

The other virus caused the expression of a “suicide gene” which, in combination with a substance called ganciclovir, kills cells that are actively dividing, in this case cancer.

“The most novel finding of our study is that the tumor, dying due to a combination of the gene with ganciclovir, releases a molecule (called HMGB1) whose function is to bind to dendritic cells and activate them so that they can be effective in mediating the immune response against cancer, “said Castro.

HMGB1 is an ancestral protein responsible for the regulation of gene expression, but now also known that mediates the immune response against brain tumors, ie, which activates T lymphocytes

“Our results show that for an effective response against the tumor is necessary to combine immunotherapy with other therapies that kill cancer such as radiotherapy or chemotherapy,” said the scientist.

Apart from the identification and elimination of cancer, this treatment also induced immunological memory against the tumor, the mice were able to eliminate one second glioma implanted in his brain two months later.

According to Castro, this treatment worked well in preclinical models of tumors that metastasize to the brain, such as melanoma.

The researcher said that this year will launch clinical trials to treat glioblastoma and already preclinical trials are underway to demonstrate the efficacy of therapy in metastatic models of brain cancer, including lung, breast, colon and pancreas .

The review of 17 studies suggested that the risk was also significantly higher during the first year of treatment.

Blood clots in the arteries are a common cause of heart attack and stroke (CVA), while those staying in the veins can cause death if taken into the lungs.

“(…) This meta-analysis showed that current use of oral estrogen increases two to three times the risk of (blood clots),” wrote Pierre-Yves Scarabin and Marianne Canonico of the Paul Brousse Hospital in France .

Hormone replacement therapy (HRT) relieves severe symptoms of menopause such as hot flashes and was popular until 2002, when a study suggested it could increase the risk of developing breast and ovarian cancer and cause stroke and other serious conditions.

The results of that investigation led to millions of women abandon the drug, which hit hard the actions of the manufacturers, including Wyeth.

However, other experts believe that this study is flawed and this week issued a statement saying that his review of dozens of studies found that HRT is safe for women with early menopause and does not increase the risk of heart disease in patients 50 to 59 years.

Previous tests had also been linked to drugs with the formation of blood clots, but the French review is the first systematic meta-analysis assesses how big the risk really. A meta-analysis is the review of several studies published on a topic.

“Although this relative risk is higher in hormone users when compared with nonusers, the absolute risk is actually very small as blood clots do not occur in this age group in healthy women without treatment “said David Sturdee, president of the International Menopause Society.

“This slightly increased risk of (forming) blood clots should not discourage women to use HRT if needed,” added Sturdee.

The analysis of eight observational studies and nine randomized controlled trials showed that hormone replacement therapy administered via a patch did not increase the risk of blood clots.

The reason for the difference between patches and pills would be the different way that estrogen is absorbed, they added. The team said further studies are needed to confirm the results.

When taken orally, estrogen enters through the digestive system and is processed by the liver. This would prevent the balance between clotting factors and blood thinners, the researchers concluded.

Anxiety disorders are the most prevalent psychiatric disorder among the general population. Anxiety and stress appear as two sides of the same coin. “Anxiety is the psychological aspect of stress and this is the somatic aspect, the biological side, anxiety,” says José Luis Carrasco, section chief of the Psychiatry and Director of the Unit Personality Disorders Clinical Hospital San Carlos, Madrid, Spain.

“Normally, anxiety and / or stress allow the individual to interact with their environment, but when they become pathological can be generated in the individual suffering, disability to cope with everyday life and an increased risk of suicide and fall into addiction . In this sense, stress and anxiety related to family and work are of greatest concern, “says Carrasco.

In the words of the expert, “anxiety disorders involve a huge social burden in terms of disability and social costs due to, among other factors that usually appear early (in adolescence) are very persistent, cause much suffering, require significant assistance partner -health, causing frequent sick leave, etc.. ”

This issue is connected with one of the greatest concerns of our time: the crisis. José Luis Carrasco believes that “the crisis syndrome affects all branches of medicine, since after several underlying symptoms of anxiety and distress, whose origin is the uncertainty about the future.”

The specialist distinguishes between “two types of conditions. On the one hand of the individual who has not lost his job and is in a more normal situation, the main problems are dizziness, headaches, lack of sleep or appetite and pain. On the other hand, are those directly affected by the crisis, either because they have lost their jobs or because they are in a critical situation. In this case there is a basis of hopelessness that leads to symptoms of depression, discouragement, tiredness or lack of interest. “

It is estimated that 25% of adults suffer the embarrassment that causes bad breath and the percentage would reach 50% among older adults. In a study that lasted 28 days and was conducted on 14 adults with halitosis, a team led by Peter Moses, a student at the School of Dentistry, State University of New York at Buffalo, found that brushing twice a day with fluoride containing triclosan and clean the surface of the tongue solve the problem.

Triclosan is an antibacterial drug used to treat acne, hand soaps, detergents and deodorants. “Most toothpastes do not contain triclosan,” said Dr. Joseph J. Zambon, who participated in the study. Triclosan is present in the Colgate Total toothpaste, which makes Colgate-Palmolive Co., which funded the study.

At the beginning and end of the study, researchers measured levels of air in the mouth with the odor-causing bacteria and analyzed tongue scrapings samples in search of 20 species of bacteria that cause bad breath. According to the authors, brushing teeth twice a day with toothpaste containing triclosan and scraping the tongue with a cleaner reduced levels of bacteria that cause bad breath of about 400 parts per billion at baseline to about 100 parts to 28 days.

“All participants solved the halitosis after using triclosan toothpaste and a tongue cleaner,” Moses said in a statement from the university. “The fear of halitosis, known halitofobia, sometimes is so great that up to 25% of people who say they do not have bad breath,” said the expert, adding: “The halitofobia is related to obsessive-compulsive disorder and even provoked suicides, so that effective therapies are needed for this problem. “

To simulate the disease, the researchers administered to the monkeys a neurotoxin that causes the disease until the animals showed tremor, rigidity and unstable posture are characteristic of Parkinson’s disease
In this disease, the loss of dopamine causes uncontrolled body movements. Therefore, the normal treatment is giving patients drugs that increase the level of the substance in the brain. However, this therapy does not maintain dopamine levels for normal operation, leading to a disorder called tardive motor.

The constant observation of animals over three years revealed a restoration of dopamine levels, corrected motor disorders and had no side effects. In its report, the scientists suggest that it is conducting a clinical trial of this treatment in humans.

Most parents panic when their child’s doctor sentenced epilepsy. In fact, the correct handling and regularly can reduce, even eliminate epileptic seizures. Epilepsy, does not normally occur due to electrical activity in the brain. This causes seizures and behavioral changes and loss of consciousness. The signs can include loss of consciousness for a certain time, convulsions, tongue stuck out, salivation, shaking or sudden black out.

There are two known types of epilepsy, epilepsy is common, a loss of consciousness, seizures throughout the body until foamy drooling and snoring breath, and muscle contractions occur resulting in the patient suddenly fell or threw the object he was holding.

Also known as partial epilepsy indicated by tingling or a feeling familiar to the one place that lasted several minutes or hours. It could also, think like a dream, disturbed memory, hallucinations, or empty the mind. Often followed by repeating the words, daydreaming, and running without a purpose.

Most patients with epilepsy due to hereditary factors. Children born to epileptic families, tend to suffer from epilepsy as well. In addition, epilepsy can also be caused by various diseases that interfere with brain function.

Epilepsy can occur due to abnormal formation of the brain (congenital), infectious disease that causes inflammation of the brain, a tumor in the brain, step over, metabolic disorders, and there is no known cause,.

Majority of epileptic children were, but epilepsy can also appear in adulthood. Cases of epilepsy in adults usually occurs because of infection or trauma to the head due to traffic accidents that cause brain bruise.

Seizure free

The drugs given to patients with epilepsy does not cure epilepsy directly, but merely to control or dilute the attack. A generally require people with epilepsy drugs are not found again until the attack within a certain time, depending on the type of epilepsy, past history of epilepsy, and brain electrical recordings.

Surgery can be done if the treatment given to patients with epilepsy do not reduce complaints. “Surgery can be performed if an MRI exam showed no gliomas or benign tumors,” Although the operation was performed, but patients with epilepsy remain mandatory anti-seizure medication.

The important thing is known parents, epilepsy does not always result in the decline of intelligence in people. Children can also be active as normal as any other healthy child remain steady as long as the drug.
