Lung cancer scans urged for some smokers, not all

Certain current or former heavy smokers should start getting yearly scans for lung cancer to cut their risk of death from the nation’s top cancer killer, government advisers said Monday — even as they stressed that the tests aren’t for everyone.

The long-anticipated decision by the influential U.S. Preventive Services Task Force says these CT scans of the lungs should be offered only to people at especially high risk: those who smoked a pack of cigarettes a day for 30 years or an equivalent amount, such as two packs a day for 15 years — and who are between the ages of 55 and 80.

That’s roughly 10 million people, but not all of them qualify for screening, said task force vice chairman Dr. Michael LeFevre, a University of Missouri family physician. Even those high-risk people shouldn’t be scanned if they’re not healthy enough to withstand cancer treatment, or if they kicked the habit more than 15 years ago.

Lung cancer kills nearly 160,000 Americans each year. Smoking is the biggest risk factor, and the more and longer people smoke, the higher their risk. Usually, lung cancer is diagnosed too late for treatment to succeed, but until now there hasn’t been a good means of early detection.

The newly recommended screening could prevent as many as 20,000 deaths a year, LeFevre said — if it’s used correctly.

That estimate assumes good candidates seek the scans. There’s no way to know if people at the highest risk will, or if instead the overly anxious will flood testing centers.

Screen the wrong people, “and we could see more harm than good,” LeFevre cautioned. “There’s a lot of room for what I would call people exploiting the recommendation. I can imagine a street-corner imaging center advertising to invite people in.”

Why not screen younger or lighter smokers? There’s no data to tell whether they’d be helped. Lung cancer is rare before age 50, and the major study that showed screening could save lives enrolled only heavy smokers starting at age 55.

But screening isn’t harm-free. A suspicious scan is far more likely to be a false alarm than a tumor, LeFevre noted. Yet patients may undergo invasive testing to find out, which in turn can cause complications.

Moreover, radiation accumulated from even low-dose CT scans can raise the risk of cancer. And occasionally, screening detects tumors so small and slow-growing that they never would have threatened the person’s life.

While screening clearly can benefit some people, “the best way to avoid lung cancer death is to stop smoking,” LeFevre added.

The task force proposed the screenings last summer but published its final recommendation Monday in the journal Annals of Internal Medicine. That clears the way for insurers to begin paying for the scans, which cost between $300 and $500, according to the American Lung Association.

Under the Obama administration’s health care law, cancer screenings that are backed by the task force are supposed to be covered with no copays, although plans have a year to adopt new recommendations.

Thicker brain sections tied to spirituality: study

For people at high risk of depression because of a family history, spirituality may offer some protection for the brain, a new study hints.

Parts of the brain’s outer layer, the cortex, were thicker in high-risk study participants who said religion or spirituality was “important” to them versus those who cared less about religion.

“Our beliefs and our moods are reflected in our brain and with new imaging techniques we can begin to see this,” Myrna Weissman told Reuters Health. “The brain is an extraordinary organ. It not only controls, but is controlled by our moods.”

Weissman, who worked on the new study, is a professor of psychiatry and epidemiology at Columbia University and chief of the Clinical-Genetic Epidemiology department at New York State Psychiatric institute.

While the new study suggests a link between brain thickness and religiosity or spirituality, it cannot say that thicker brain regions cause people to be religious or spiritual, Weissman and her colleagues note in JAMA Psychiatry.

It might hint, however, that religiosity can enhance the brain’s resilience against depression in a very physical way, they write.

Previously, the researchers had found that people who said they were religious or spiritual were at lower risk of depression. They also found that people at higher risk for depression had thinning cortices, compared to those with lower depression risk.

The cerebral cortex is the brain’s outermost layer made of gray matter that forms the organ’s characteristic folds. Certain areas of the cortex are important hubs of neural activity for processes such as sensory perception, language and emotion.

For the new study, the researchers twice asked 103 adults between the ages of 18 and 54 how important religion or spirituality was to them and how often they attended religious services over a five-year period.

In addition to being asked about spirituality, the participants’ brains were imaged once to see how thick their cortices were.

All the participants were the children or grandchildren of people who participated in an earlier study about depression. Some had a family history of depression, so they were considered to be at high risk for the disorder. Others with no history served as a comparison group.

Overall, the researchers found that the importance of religion or spirituality to an individual – but not church attendance – was tied to having a thicker cortex. The link was strongest among those at high risk of depression.

“What we’re doing now is looking at the stability of it,” Weissman said.

Her team is taking more images of the participants’ brains to see whether the size of the cortex changes with their religiosity or spirituality.

“This is a way of replicating and validating the findings,” she said. “That work is in process now.”

Dr. Dan Blazer, the J.P. Gibbons Professor of Psychiatry at Duke University Medical Center in Durham, North Carolina, said the study is very interesting but is still exploratory.

“I think this tells us it’s an area to look at,” Blazer, who was not involved in the new study, said. “It’s an area of interest but we have to be careful.”

For example, he said there could be other areas of the brain linked to religion and spirituality. Also, spirituality may be a marker of something else, such as socioeconomic status.

Blazer added that it’s an exciting time, because researchers are actively looking at links between the brain, religion and risk of depression.

“We’ve seen this field move from a time when there were virtually no studies done at all,” he said.

Weissman said the mind and body are intimately connected.

“What this means therapeutically is hard to say,” she added.

Doctors Spend Very Little Time Talking About Sex With Teens

A new study published in JAMA Pediatrics has revealed that many doctors spend very little time discussing sex with their teenage patients – if they do at all. According to Counsel and Heal, researchers from Duke University analyzed the audio recordings of 253 annual doctors’ visits for adolescents between the ages of 12 and 17

A new study published in JAMA Pediatrics has revealed that many doctors spend very little time discussing sex with their teenage patients – if they do at all.

According to Counsel and Heal, researchers from Duke University analyzed the audio recordings of 253 annual doctors’ visits for adolescents between the ages of 12 and 17. They found that the doctors discussed sex in only 65 percent of the visits, with the conversations lasting an average of 36 seconds. In the other 35 percent of visits, the topic of sex wasn’t brought up at all.

The study’s authors argue that such limited exchanges won’t help meet the “sexual health prevention needs of teens.”

“It’s hard for physicians to treat adolescents and help them make healthy choices about sex if they don’t have these conversations,” said lead author Stewart Alexander, associate professor of medicine at Duke. “For teens who are trying to understand sex and sexuality, not talking about sex could have huge implications.”

The study also revealed that only 4 percent of the teenage patients had prolonged discussions about sex with their doctors. Additionally, the female patients were twice as likely as their male counterparts to spend more time talking about sex.

Slow eating may reduce hunger but not calorie intake

Previous studies suggest that eating speed may affect how many calories the body consumes. But new research suggests that eating speed, rather than caloric intake, may have more of an impact on hunger suppression.

This is according to a study published in the Journal of the Academy of Nutrition and Dietetics.

Investigators from the Department of Kinesiology at Texas Christian University say that previous research has mainly analyzed the link between calorie intake and eating speed in individuals of a healthy weight.

But this new study looked at the relationship between eating speed and energy intake in 35 overweight and obese individuals and compared the results with 35 individuals of a healthy weight.

New research suggests that eating slowly may reduce hunger but may not have a significant impact on calorie intake.
Both groups were required to consume one meal a day within a controlled environment over 2 days. Both meals were the same for each group, and the energy content (calories) and weight of each meal were measured prior to consumption.

For one meal, both groups were asked to eat at a slow pace. During this meal, they were asked to imagine they had time constraints in which to finish, to take small bites, thoroughly chew their meal and pause and set down their cutlery between bites.

For the other meal, both groups were asked to eat their food at a fast pace. They were asked to imagine they had to finish their meal within a certain time frame, take large bites, chew quickly and to not put down their cutlery between bites.

Slow eating ‘may reduce hunger’
Results of the study revealed that both groups felt less hungry an hour after the slow-eating condition, compared with the fast-eating condition.

Dr. Meena Shah, lead author of the study, explains:

“In both groups, ratings of hunger were significantly lower at 60 minutes from when the meal began during the slow compared to the fast-eating condition. These results indicate that greater hunger suppression among both groups could be expected from a meal that is consumed more slowly.”

Both groups also demonstrated a higher water consumption throughout the slow-eating condition, with 12 ounces of water consumed, compared with 9 ounces throughout the fast-eating condition.

Dr. Shah says the higher consumption of water during the slow-eating condition may have caused stomach distention in the participants and therefore may have affected the level of food consumption.

No impact on calorie intake for obese group
However, when analyzing the participants’ calorie intake, the researchers found that only the subjects of a healthy weight saw a reduction in calorie intake after consuming the meal in the slow-eating condition. The obese/overweight group ate 58 calories less, while the normal weight group ate 88 calories less.

“A lack of statistical significance in the overweight and obese group may be partly due to the fact that they consumed less food during both eating conditions compared to the normal-weight subjects,” says Dr. Shah.

She adds that the overweight and obese participants may have felt self-conscious during the meal, and so it is possible that this may have caused them to eat less.

According to the Centers for Disease Control and Prevention (CDC), more than one-third of the US adult population is obese. Obesity rates have increased from 14.5% of the US population in 1971-74 to 35.9% of the population in 2009-10.

Dr. Shah notes that with obesity rates continuing to rise, information on how individuals of a different weight approach and consume food may help in the development of strategies to reduce calorie intake.

But she says that findings from this study show that slowing the speed of eating “may help to lower energy intake and suppress hunger levels and may even enhance the enjoyment of a meal.”

Cholesterol linked to Alzheimer’s protein, unclear why

Patterns of “good” and “bad” cholesterol usually associated with heart risks also predicted the levels of Alzheimer’s-related beta amyloid protein seen in the brains of study participants.

“One of the important themes emerging from dementia research over the past 15 years is that there are intriguing connections between vascular disease and Alzheimer’s disease,” Bruce Reed, who led the research, told Reuters Health by email.

Reed is a professor and associate director of the University of California Davis Alzheimer’s Disease Research Center.

“It has become increasingly clear that what have been traditionally thought of as vascular risk factors – things like hypertension, diabetes and elevated cholesterol – are also risk factors for Alzheimer’s disease,” Reed said.

In previous work, Reed and his colleagues found a connection between overall vascular risk and levels of brain amyloid.

“Amyloid deposition is important because it is widely believed by scientists to be a key event that initiates a chain of events that eventually, years later, results in the dementia of Alzheimer’s disease,” Reed said.

“There was also previous work in cell cultures and with animals that suggested that cholesterol plays an important role in promoting the deposition of amyloid in the brain,” Reed said.

For the new study, published in JAMA Neurology, the researchers examined the cholesterol levels of 74 elderly people who had normal to mildly impaired cognitive function. Researchers also measured brain deposits of beta amyloid protein with positron emission tomography (PET scanning).

They found that on average, participants who had higher levels of the “bad” LDL cholesterol and lower levels of “good” HDL cholesterol also had higher levels of amyloid in the brain.

Elevated LDL-cholesterol is associated with cardiovascular disease while high levels of HDL-cholesterol are thought to protect against heart disease.

“We think this is a very important finding, but as with all novel findings it needs to be replicated,” Reed said. “Assuming that the basic pattern is found in other groups of patients, it is urgent that we try to understand the mechanism(s) behind this finding.”

“Cholesterol in blood and cholesterol in brain are separate ‘pools,’ walled off from one another by the blood brain barrier. We measured cholesterol in blood. So that is one question that needs to be answered – how do cholesterol levels in blood and in brain influence each other,” Reed said.

“And in the brain, it is not entirely understood how changing cholesterol levels might reduce amyloid deposition. We are very interested in the idea that higher HDL (‘good’) cholesterol levels may help the brain more efficiently clear the toxic amyloid at an early stage,” Reed said.

“If those questions were understood we could begin to think about how to change cholesterol levels so as to prevent the buildup of amyloid,” Reed added.

In other studies, some researchers have found evidence that LDL cholesterol-lowering drugs, such as statins, might offer some protection against Alzheimer’s disease, but the results have been inconsistent.

Reed’s team didn’t see any associations between current use of cholesterol medication by the participants and their amyloid levels.

In their report, Reed and his coauthors caution that the study does not prove cholesterol is directly affecting amyloid deposition. For instance, they write, unhealthy cholesterol could be linked to vascular damage, such as small strokes, and those micro-injuries could be the reason for the protein deposits.

He encourages people to follow the advice of their doctor and try to achieve the cholesterol guidelines set by the American Heart Association.

“A remarkable number of people who are alive now will live into their 80s or beyond – the period of highest risk for Alzheimer’s. This study is one more piece of evidence that what we do now can shape our health positively in those years,” Reed said.

A boy received lungs after the nation’s organ transplants rules.

Javier Acosta can finally start to breathe easy. The New York boy received a new set of lungs after challenging the nation’s organ transplants rules.

Acosta, as well as Pennsylvania’s Sarah Murnaghan, forced the Organ Procurement and Transplantation Network to change the rules that allowed adolescents and adults to receive organs based on their needs or sickness. Up until now, children had to wait until they turned 12 years old to be put on the waiting list.

Javier had surgery on October 13th after his mother Milagros Martinez successfully filed a lawsuit allowing him to be put on the same list as those over 12. Javier’s mom waited to tell everyone the news about the transplant until he recovered from the surgery.

Javier suffers from the genetic disease cystic fibrosis. The disease is extremely familiar to his family. Javier’s brother died from cystic fibrosis four years ago, just months before he turned 12 and would have been considered an adolescent.

Javier remains under hospital supervision from the transplant. His mother says his prognosis is good and he is “doing fine.”

Vitamin E may slow spread of mild-to-moderate Alzheimer’s disease

Researchers say vitamin E might slow the progression of mild-to-moderate Alzheimer’s disease — the first time any treatment has been shown to alter the course of dementia at that stage.

In a study of more than 600 older veterans, high doses of the vitamin delayed the decline in daily living skills, such as making meals, getting dressed and holding a conversation, by about six months over a two-year period.

The benefit was equivalent to keeping one major skill that otherwise would have been lost, such as being able to bathe without help. For some people, that could mean living independently rather than needing a nursing home.

Vitamin E did not preserve thinking abilities, though, and it did no good for patients who took it with another Alzheimer’s medication. But those taking vitamin E alone required less help from caregivers — about two fewer hours each day than some others in the study.

“It’s not a miracle or, obviously, a cure,” said study leader Dr. Maurice Dysken of the Minneapolis VA Health Care System. “The best we can do at this point is slow down the rate of progression.”

The U.S. Department of Veterans Affairs sponsored the study, published Tuesday by the Journal of the American Medical Association.

No one should rush out and buy vitamin E, several doctors warned. It failed to prevent healthy people from developing dementia or to help those with mild impairment (“pre-Alzheimer’s”) in other studies, and one suggested it might even be harmful.

Still, many experts cheered the new results after so many recent flops of once-promising drugs.

“This is truly a breakthrough paper and constitutes what we have been working toward for nearly three decades: the first truly disease-modifying intervention for Alzheimer’s,” said Dr. Sam Gandy of Mount Sinai School of Medicine in New York. “I am very enthusiastic about the results.”

About 35 million people worldwide have dementia, and Alzheimer’s is the most common type. In the U.S., about 5 million have Alzheimer’s. There is no cure and current medicines just temporarily ease symptoms.

Researchers don’t know how vitamin E might help, but it is an antioxidant, like those found in red wine, grapes and some teas. Antioxidants help protect cells from damage that can contribute to other diseases, says the federal Office on Dietary Supplements. Many foods contain vitamin E, such as nuts, seeds, grains, leafy greens and vegetable oils. There are many forms, and the study tested a synthetic version of one — alpha-tocopherol — at a pharmaceutical grade and strength, 2,000 international units a day.

Years ago, another study found that the same form and dose helped people with more advanced Alzheimer’s, and many were prescribed it. But vitamin E fell out of favor after a 2005 analysis of many studies found that those taking more than 400 units a day were more likely to die of any cause.

The new study involved 613 veterans, nearly all male, 79 years old on average, with mild to moderate Alzheimer’s, at 14 VA centers. All were already taking Aricept, Razadyne or Exelon — widely used, similar dementia medicines.

Participants were placed in four groups and given either vitamin E, another dementia medicine called memantine (its brand name is Namenda), both pills or dummy pills.

After a little more than two years of follow-up, those on vitamin E alone had a 19 percent lower annual rate of decline in daily living skills compared to the placebo group. Memantine made no difference, and vitamin E did not affect several tests of thinking skills.

“It’s a subtle effect but it’s probably real,” Dr. Ron Petersen, the Mayo Clinic’s Alzheimer’s research chief, said of the benefit on daily living from vitamin E. “That has to be weighed against the potential risks” seen in earlier studies, he said.

Heather Snyder, director of medical and scientific operations for the Alzheimer’s Association, said the group’s position is that “no one should take vitamin E for Alzheimer’s disease or other memory issues except under the supervision of a physician,” because it can interfere with blood thinners, cholesterol drugs and other medicines.

The new results also need to be verified in a fresh study that includes more women and minorities, she said.

4 reasons why pregnant women should consider the flu shot

With flu season in full swing, attention must be paid to pregnant women when it comes to this potentially dangerous virus.

Expectant mothers must be encouraged to get a flu shot – and if they notice flu-like symptoms, they need to seek medical help immediately.

The mortality and complications of the flu in pregnancy are enormous. And these complications are not only significant to the mother, but can also affect her baby by causing premature labor, premature delivery and even death.

There are four key issues that make the flu so problematic in pregnancy.

The first one is that pregnant women have more difficulty in fighting off infections – both viral and bacterial. The reason for this is that the immune system often is underperforming due to the hormonal changes in pregnancy, which can have effects similar to those seen in people on chronic steroid medications.

Once a severe infection develops, the chances the virus or bacteria can overrun the mother are proportionally higher.

The second point has to do with those pregnancy hormones themselves, in particular – progesterone. One of the effects of progesterone in pregnancy is that it creates capillary engorgement and swelling of the lining of the nose and oral pharynx. This predisposes a pregnant women to contract viruses and infuse them quickly into circulation.

Next, there are significant physical changes in the breathing system of a pregnant women. There’s an upward displacement of the diaphragm, which grows over time as the belly becomes bigger – and means the total lung capacity is decreased. What happens is the expiratory reserve volume and the residual volume of the lungs are decreased by 20 percent, so you have less air every time you take a breath.

Now, imagine having the flu and having your lungs full of mucous. With these changes, if the patient is lying down, the chest wall function makes it harder for her to breathe.

This brings me to my last point of significance. The need for oxygen is much greater in pregnant women than non-pregnant women. The reason there is an increased oxygen consumption is because you’re now breathing for two — literally.

Ultimately, the flu can infect a pregnant woman’s lungs, not only with the flu virus, but with a secondary infection – like bacterial pneumonia, making oxygen delivery to the mother and child more problematic – and could even lead to death.

If you are pregnant, and haven’t already gotten your flu shot, you should talk to your doctor about it right away.

Boy stabbed by syringe found in Wal-Mart sweatshirt he got for Christmas

A 16-year-old boy in south Washington is undergoing multiple blood tests after he was stabbed by a syringe hidden inside a sweatshirt he received for Christmas, The Daily News Online reported.

According to Nanette Snyder, her son was modeling the new hoodie – purchased from Wal-Mart – on Christmas day when he stuck his hand in the front pocket. He then felt a stab of pain and pulled his hand out – revealing a syringe stuck in his finger. Another syringe was also found in the sweater’s pocket, and both of the syringes appeared to be used.

Snyder immediately took her son to the emergency room, where he underwent testing for HIV and hepatitis. The family is still waiting for the test results, though the boy will need additional testing throughout the year even if all results are initially negative.

“I feel like crap,” Snyder told The Daily News Online. “It’s a horrible feeling.”

A corporate spokesperson for Wal-Mart said they are investigating the incident.

“We take this very, very seriously and we want to get to a better idea of what could have happened,” she said.
