Médicos encontram galho de árvore em pulmão de russo

da BBC Brasil

Um galho de árvore de 5 cm foi encontrado no pulmão de um homem na Rússia, segundo a televisão estatal russa.

Artyom Sidorkin percebeu que algo estava errado quando começou a sentir fortes dores no peito e a tossir sangue. Médicos pensaram que Artyom tinha um tumor em um dos pulmões.

Ao fazer uma biópsia, os médicos se surpreenderam ao descobrir que não era um tumor, e sim um pequeno galho. Mas não se sabe como o galho teria entrado no pulmão.

Olga Baranova, bióloga da Udmurt State University, diz que é impossível um planta crescer de uma semente dentro do pulmão humano, por que para crescer as plantas precisam de luz, água e uma temperatura certa.

Angelina Jolie Is Pregnant Again?

April 15th, 2009 1:04pm EDT

Angelina JolieAngelina Jolie and Brad Pitt are expecting baby number seven, Star magazine reports. An insider confirmed that the actress is about 10 weeks into her pregnancy and that the couple had been trying for another baby for a few months.

"Yes, Angie is pregnant," said the family insider. The pregnancy might be viewed as a relationship saver also, as it was recently reported that the couple has been fighting a lot lately due to Angelina having been angered by catching Brad rubbing the back of one of their nannies.

According to a recent report, the couple had been planning to adopt a child from India, but sources said that they put the adoption on hold after filling out the necessary paperwork because of "all their other commitments." Perhaps the pregnancy was the real reason.

Stories about Angelina's extreme liquid diet and explosive fights with Brad:

An aspirin-a-day can make your brain explode

Wednesday April 15,2009
By Jo Willey, Health Correspondent

A DAILY dose of the 'wonder drug' aspirin can cause bleeding in the brain, researchers have found.

Brain scans on more than 1,000 patients revealed a 70 per cent higher incidence of microscopic bleeding among those taking the drug.

The shock findings will be of major concern to the millions of Britons who take aspirin every day to stave off fatal heart attacks and strokes.

The drug is used to thin the blood, which reduces the risk of dangerous clots forming in key blood vessels.

At the moment, I would only give it to people at high risk of heart attack

Dr Mike Knapton, associate medical director of the British Heart Foundation

Previous research has already shown that anti-clotting medicines can increase the risk of bleeding in the gastrointestinal tract – the oesophagus, stomach, or intestines.

But the new findings suggest they can also raise the odds of “cerebral microbleeds” that can be a sign of brain vessel disease.

British experts welcomed the findings but urged people using aspirin not to suddenly stop taking their medication.

Dr David Werring, honorary consultant neurologist at the National Hospital for Neurology and Neurosurgery in London, said: “More research is needed to decide whether these micro-bleeds raise the risk of serious bleeding in the brain in people who take aspirin.

"Bleeds to the surface of the brain suggest a condition of a hardening of the arteries which may increase the risk of brain haemorrhage.

“But it is clear for the vast majority of aspirin users that the benefits far outweigh the risks.”

The latest study by Dutch researchers, published online in the Archives of Neurology, found no increased incidence of microbleeds in people taking clot-preventing drugs that act in different ways, such as heparin.

Both aspirin and carbasalate calcium, a chemical relative of aspirin, prevent the formation of clots by acting against platelets, the blood cells that form clots.

Aspirin is typically given to people at risk of heart attacks or stroke but can also be prescribed to patients with high cholesterol, high blood pressure or diabetes.

As a long-term anticoagulant or a preventative measure for heart disease, the standard dose is 75mg of aspirin a day.

As a painkiller, the recommended dose is 275 to 300mg every six to eight hours, not exceeding three doses a day.

The study found people who took a relatively low dose of aspirin – 89mg – compared with those who took 102.8mg of carbasalate calcium – the equivalent of 82.2mg of aspirin – suffered more microbleeds.

At equivalent dosages, aspirin users were at nearly four times the risk of microbleeds compared with carbasalate calcium users.

The researchers at Erasmus MC University Medical Centre in Rotterdam found that when microbleeds occur in certain brain areas, they may indicate a type of small vessel disease known as cerebral amyloid angiopathy.

This involves the accumulation of a protein often related to Alzheimer’s disease which causes degeneration of smooth muscle cells and increases the susceptibility of blood vessels to rupture.

Dr Meike Vernooij and his colleagues accepted that the beneficial effects of anti-clotting drugs for individuals at risk for heart attack and stroke typically outweighed any risks of bleeding.

But they added: “Nevertheless, it may be that in selected persons such as those with signs of cerebral amyloid angiopathy, this risk-benefit ratio may differ for certain drugs like aspirin, thus influencing treatment decision.”

Dr Mike Knapton, associate medical director of the British Heart Foundation, said: “Aspirin is an antiplatelet drug and it is not surprising that it increases the risk of microbleeds.

“With any drug you have got to balance the risks of it versus the benefits, so you wouldn’t give aspirin to absolutely everybody.

“At the moment, I would only give it to people at high risk of heart attack.”

Blacks Less Likely to Get Optimal Lung Cancer Treatment

04.12.09, 08:00 PM EDT

Disparity in care is as wide today as it was in the early '90s, study says

MONDAY, April 13 (HealthDay News) -- Black patients with lung cancer are less likely than white patients to receive recommended chemotherapy and surgery, a new study finds.

Disparities in lung cancer treatments were as large in 2002 as they were back in the early 1990s, even though there have been efforts to decrease those inequalities in treatment, the study said.

"This study shows what most of the previous research has shown -- that disparities in treatment patterns [still exist] between blacks and whites," said Katherine S. Virgo, director of health services research the American Cancer Society, who was not involved in the study.

The findings were published online April 13 in the journal Cancer.

For the study, Dale Hardy, of the University of Texas School of Public Health, and colleagues collected data on 83,101 people 65 and older with non-small cell lung cancer -- the most common form of lung cancer -- between 1991 and 2002.

The researchers found that blacks with early-stage cancer were 37 percent less likely to receive recommended surgery and 42 percent less likely to receive recommended chemotherapy, compared with whites.

Among patients with later-stage lung cancer, blacks were 57 percent less likely to receive recommended chemotherapy than whites.

The researchers speculated that there may be several reasons for the disparities in care: Blacks are less likely to get an accurate diagnosis and get recommendations for surgery, but blacks are also more likely to decline surgery, the study authors said.

There also may be cultural differences, the researchers said. For example, many blacks distrust the health-care system. Also, blacks tend to rely on prayer and alternative healing and believe that "when your time is up, it is up," the researchers said.

"In addition, blacks are most often seen at county hospitals, which often provide lower quality medical therapy," Hardy's group noted.

"In conclusion, there were substantial disparities in receiving recommended treatments between blacks and whites, and these disparities have been relatively stable during the past 12 years," the study authors wrote. "To reduce disparities in receipt of treatment for non-small cell lung cancer, efforts should focus on providing appropriate quality treatment and educating blacks on the value of having these treatments."

Virgo said disparities in treatment between blacks and whites are common for a number of diseases and conditions. "This is not something that is specific to non-small cell lung cancer," she said.
