Women May Have Natural Defense Against Common STD

'Trich' causes discomfort for some, but is symptomless in othersWhether loss of virginity was a positive

HealthDay Reporter

THURSDAY, May 30 (HealthDay News) -- Women appear to have a natural defense against the world's most common sexually transmitted infection, a new study says.

This natural protective barrier consists mainly of lactic acid bacteria -- called lactobacilli.

The finding appears online May 29 in the journal Sexually Transmitted Infections.

The discovery could lead to new treatments for "trich," which affects an estimated 174 million women and men around the world each year, according to a journal news release.

Trich is caused by the parasite Trichomonas vaginalis or T. vaginalis. Symptoms of the infection include pain, irritation and discharge. About 50 percent of all people who have this condition, however, don't develop symptoms and are unaware that they are infected.

Researchers Augusto Simoes-Barbosa, of the University of Auckland in New Zealand, and colleagues examined how easily three different strains of T. vaginalis bound to vaginal cells. They repeated the process when nine different types of lactobacilli were also present.

In the vast majority of instances, lactobacilli prevented the parasite from binding to the cells. Some types of lactobacilli were better at preventing the parasite from binding to the cells than others, the study authors pointed out.

"This study reinforces the important role that our microbiomes play in health, infection and disease," they wrote. "Understanding the role that Lactobacillus plays in T. vaginalis infection/disease might reveal new therapeutic approaches, which include taking advantage of the natural probiotic activity of lactobacilli."

Tofu-Rich Diet May Help Women With Lung Cancer Live Longer

Chinese study found eating high amounts before diagnosis boosted survival ratesLowered blood pressure, cholesterol levels may be

By Mary Brophy Marcus

HealthDay Reporter

TUESDAY, March 26 (HealthDay News) -- Eating tofu and other soy foods may help women who develop lung cancer increase their odds of living longer.

A study of women from Shanghai, China, published in the March 25 issue of the Journal of Clinical Oncology, links high soy consumption before a lung cancer diagnosis with longer survival.

"This is the first study to suggest an association between soy food consumption and lung cancer survival," said study author Dr. Gong Yang, a research associate professor of medicine in the division of epidemiology at Vanderbilt University Medical Center, in Nashville.

Eating soy products in small amounts in the years preceding a lung cancer diagnosis didn't seem to pose a benefit, though.

Lung cancer is the leading cause of death among women in the world. It forms in the tissues of the lungs, usually in the cells that line the air passageways. The five-year survival rate is poor compared to breast cancer; it is estimated that by 2012, lung cancer will cause twice as many deaths as breast cancer, Yang said.

Cigarette smoking is the top cause of the disease in the United States, according to the U.S. Centers for Disease Control and Prevention, but in the study, most of the women from China were nonsmokers.

One expert noted another difference between the two populations of women that does not bode well for Chinese women.

"Far more never-smoking women in Asia get lung cancer than in the United States," said Dr. Jyoti Patel, an associate professor of medicine at the Robert H. Lurie Comprehensive Cancer Center at the Northwestern University Feinberg School of Medicine, in Chicago. "We're not sure why this is, but they may have a predilection for developing mutations ... that cause lung cancer to grow."

The study participants were part of a larger observational study called the Shanghai Women's Health Study, which tracked the incidence of cancer in about 75,000 women. Diet information was collected, including how much soy food -- such as soy milk, tofu, fresh and dry soybeans, and soy sprouts -- women ate.

The authors reported that about 450 women were diagnosed with lung cancer during the study. They were divided into three groups according to the amount of soy food they had eaten before their lung cancer diagnosis. The highest intake levels of tofu were equal to about 4 ounces a day, while the lowest soy consumers ate less than 2 ounces daily.

During the study, more than 300 of the lung cancer patients died, Yang said. Sixty percent of the women in the highest soy-eating group and 50 percent in the low soy consumer group were alive twelve months after diagnosis. A patient's risk of death decreased with increasing soy intake, but leveled off at 4 ounces of daily tofu consumption.

Transfusions With Heart Surgery Might Raise Infection Risk

Delicate balance exists between treating anemia, avoiding side effects from infusion of red blood cells, study saysAfter 3 weeks cells' ability to deliver oxygen

By Mary Elizabeth Dallas

HealthDay Reporter

THURSDAY, May 30 (HealthDay News) -- Patients who receive a red blood cell transfusion during or after heart surgery may be at greater risk for infection, according to a new study.

However, the use of platelets during transfusions does not appear to carry a similar risk. Limiting red blood cell use could result in fewer major postoperative infections, the researchers suggested.

The study is published in the June issue of the Annals of Thoracic Surgery.

"A common problem for many surgeons, and thereby the patient, is how to balance the risk of surgery-induced anemia with the increased risk of infection when using red blood cell transfusion to correct the anemia," study author Dr. Keith Horvath, at the U.S. National Heart, Lung, and Blood Institute, said in a journal news release.

"Through this study, we hoped to shed light on the problem and to encourage hospitals and surgeons to examine cell-salvage techniques and other alternatives to [red blood cell] transfusion during and after cardiac surgery," he explained.

The observational study, conducted by the Cardiothoracic Surgical Trials Network, involved nearly 5,200 adults who underwent heart surgery between February and September 2010.

"Our study enrolled a large population of patients from a number of different institutions who were undergoing any type of cardiac surgery," Horvath noted. "This large patient set enabled us to better examine the relationship between transfusion and infection in a very diverse population."

Of the study's participants, 48 percent received a red blood cell transfusion and 31 percent received platelets.

With red blood cell transfusions, 84 percent took place during a transplant or left ventricular assist device implantation. Meanwhile, 63 percent occurred during thoracic aortic procedures, 45 percent took place during isolated coronary artery bypass grafting surgery and 40 percent occurred during isolated valve surgery.

The study found that 65 days after surgery, 5 percent of the patients developed at least one major infection, such as pneumonia, C. difficile colitis (a bacterial infection in the colon) and bloodstream infections.

With each red blood cell unit transfused, there was a 29 percent increase in infection risk. In contrast, platelets transfused along with more than four unit of red blood cells was associated with a lower infection risk.

"Few in regulatory agencies have grasped the complex but real relationships between red cell transfusions, infection and ... readmissions," Dr. Bruce Spiess, from Virginia Commonwealth University Medical Center, wrote in a related journal commentary.

Spiess concluded that improvements in blood management among cardiac teams would enhance patient safety, reduce hospital-acquired infections and reduce critical blood shortages.

However, the researchers pointed out that since this was an observational study, the reported associations cannot be considered as a cause-and-effect relationship.

Ranting on Websites May Just Make You Angrier

Studies link Internet venting to short-term relaxation, long-term frustrationRisks for diabetes, cancer and heart disease all

By Barbara Bronson Gray

HealthDay Reporter

FRIDAY, March 22 (HealthDay News) -- It's so tempting. You read something on a website about a hot-button issue that makes you mad and you've got to respond. Before you know it, you're verbally sparring with a stranger. But you may want to think twice before jumping into the fray.

While you might like getting your point of view off your chest, over the long term your rants may be making you less happy and more angry, suggest two new studies by a single research team.

The first study showed that while visitors to common "rant" websites reported feeling more relaxed immediately after posting a comment, overall they tend to experience more anger in general and can express their frustration in maladaptive ways.

The second study found that both reading other people's rants and writing your own are associated with negative mood shifts. The research was published online in the journal Cyberpsychology, Behavior, and Social Networking.

"The Internet brings out impulsivity problems more than anything else," said lead author Ryan Martin, an associate professor of human development and psychology at the University of Wisconsin-Green Bay. "It's too easy to respond right away when you are most angry."

Martin said while the study focused solely on rant websites that are devoted to back-and-forth virtual screaming, the research has implications for Facebook and Twitter, and even news sites and blogs. He said the combination of being anonymous by using a screen name and having what he calls "social distance" reduce an individual's sense of restraint or caution about how to interact.

Websites that function as virtual punching bags reinforce harmful behavior, Martin said. "Most of these sites encourage venting as a way of dealing with anger," he said. "They think of venting as a healthy adaptive approach, and it's not."

For some people, venting online is caused by a sense of powerlessness and a feeling that they just can't make a difference, Martin said. A third study he did related to the published research looked at the content of rant sites and found that "people are angry at big groups of people: Democrats, Republicans, illegal immigrants," he said. "People want to feel they're doing something and think just expressing their feelings to the world will help."

Martin said venting has been described as putting a fire out with gasoline. But it's not actually the anger that's detrimental, according to the researchers. "There is nothing wrong with being angry and there are lots of things to be angry about, and that is healthy," said Martin. But he added that a healthier and more effective approach is to get involved and do something to effect the kind of change you want, or focus on problem solving.

In Dating Game, Narcissists Get the Girl

Self-admiring men attract mates more easily, study finds Self-admiring men attract mates more easily,

By Kathleen Doheny

HealthDay Reporter

THURSDAY, May 30 (HealthDay News) -- Men with high levels of narcissism -- an unrealistically positive self-image coupled with feelings of entitlement -- have an easier time than others attracting a potential mate, new German research says.

"Narcissism is linked to mate appeal in a real-life situation," said Michael Dufner, a researcher at Humboldt University of Berlin, who led the study.

The research is published in the July issue of the journal Personality and Social Psychology Bulletin.

Dufner and his team first measured narcissism levels in 61 men with an average age of 25, who were invited to join a courtship study in Germany. "We focused on narcissism as a personality trait, not the personality disorder," he said. "This means that everybody has a certain narcissism level -- for some it is higher, for others lower."

Next, the researchers asked the men to approach women they did not know on the street and get contact information. It could be a phone number, email or Facebook contact.

Research assistants followed the men (which the men were aware of), observing the interactions. Dufner decided to focus on men in this study because men traditionally court a potential mate in this way, compared to women's typically more subtle approaches, such as flirting, he said.

"We tested if individuals with higher narcissism scores are more appealing," he said.

On average, the men approached about 23 women. To rule out the possibility that the more narcissistic men were more selective in who they approached, the researchers analyzed each woman who was approached on her physical attractiveness and manner of dress. The narcissists weren't more selective.

The narcissistic guys did get the girl more often. The higher the level of narcissism, the more likely they were to get more contacts.

"The effect was not due to high self-esteem, but indeed the narcissism," Dufner said. The physical attractiveness and social boldness of the narcissists were the two likely reasons for their appeal to women, he said.

Dufner offered some caveats about the research, though. "We were not able to directly test the causality underlying the association between narcissism and physical attractiveness," he said.

One possibility, he said, is that physical attractiveness may be a partial cause of narcissism, as other researchers have suggested.

For narcissists -- and the women they seek -- the news is not all good, Dufner said. "Narcissists are charming and appealing at first sight, but they are not long-term romantic partners," he said.

The study findings confirm what many experts have long suspected, said Jean Twenge, a professor of psychology at San Diego State University who has written about narcissism. "Narcissists are very good at initiating relationships," she said. "On first impression, they come across as confident and charming. The problems arise later on, when you realize that he doesn't actually care about you -- it's all about him."

Twenge was not involved in the study, but reviewed the findings.

Caution is the byword for those attracted to narcissists, both experts agreed. "In the long run, narcissists made bad relationship partners," Twenge said. "They lack empathy and have a difficult time taking someone else's perspective."

Twenge said she does understand why women fall for narcissists. "The initial appeal of narcissists comes from their assertiveness and confidence," she said. "These are stereotypically masculine traits that many women find appealing."

Now a BMI of 18.7; still healthy?

Here's the deal.  We went on vacation in May and I stopped breastfeeding my son.  Within days, I could see 6 pack abs and thought..."woah"....

So when we got home, I weighed myself, and at 5'8", I'm now 123 lbs.  I lost some body fat I guess due to breastfeeding.  I am also less hungry and naturally full at about 1900 - 2000 calories, despite my intense workouts 4 times a week.

Everything appears to be normal and I feel great.  Should I be worried about the sudden weight loss? 

Have to admit...it looks really F-ing good!!!  I am so cut right now!  Never had a 6 pack.  My body fat must be at around 17% or so.

Gene Therapy May Protect Against Flu Pandemics

Study found coaxing cells in the nose to make super antibodies protected mice and ferrets from pandemic strainsSick athletes should put off vigorous workouts.

By Brenda Goodman

HealthDay Reporter

WEDNESDAY, May 29 (HealthDay News) -- Gene therapy that turns cells in the nose into factories that crank out super antibodies against the flu protected mice and ferrets against lethal doses of several pandemic strains of the virus.

If the approach works in humans, it could offer several important advantages over flu vaccines, said study author Dr. James Wilson, a professor of pathology and laboratory medicine at the University of Pennsylvania, in Philadelphia.

Because the therapy can be made ahead of time and fights many different strains, it might give doctors a faster way to thwart flu pandemics.

Currently, doctors race to identify dangerous new types of flu. They then have to develop a vaccine that targets the new strain. The vaccine is then grown in chicken eggs and tested for safety. It takes between three and six months to manufacture large quantities of vaccines against the flu.

"By the time we realize it's a potential pandemic, it's too late," Wilson said. "The timeliness of deploying the seasonal flu vaccine approach for pandemics is not the best way to go."

Vaccines, which prime the body to remember to attack incoming pathogens, also don't do the best job of protecting people who have diminished immune function, such as seniors and those with chronic health problems.

The new treatment, which is delivered through a nasal spray, gets around that problem because it doesn't require the body to mount an immune attack.

Instead, the nasal spray contains many copies of small, harmless viruses called adeno-associated viruses. The simple genome of these viruses can be altered in the lab to carry instructions for making special proteins called broadly neutralizing antibodies.

Broadly neutralizing antibodies are rare super antibodies that are capable of disarming many kinds of flu strains.

When researchers insert the instructions for making those antibodies into the genome of adeno-associated viruses, the viruses act like Trojan horses. They infect cells in the nose, inject the altered genetic material and turn the cells into factories that crank out many copies of the broadly neutralizing proteins.

"The way I envisioned it was sort of a bioshield," Wilson said. "I wanted to focus the production of the antibody to the site where flu enters our body."

In animal tests, researchers showed that mice, ferrets and monkeys made many copies of the super antibody after they inhaled the gene therapy treatment. And the protection seemed to last for a while. Experts note, however, that promising research in animals often does not pan out in humans.

"In mice, it persists up to a year," Wilson said. "In monkeys, we think we're going to see expression up to six months."

The treatment also appears to work pretty quickly. Wilson said the animals were fully protected about three days after their nasal passages were swabbed.
