The findings, released online Nov. 19 by the C.S. Mott Children’s Hospital National Poll on Children’s Health, show that parents have a variety of concerns about their children’s safety on the Internet.

The researchers found that 81 percent of parents surveyed said their children aged 9 to 17 use the Internet without being supervised by an adult. Almost half have profiles on social-networking sites such as MySpace and Facebook; the number grows to two-thirds among kids aged 13 to 17.

Among parents whose kids go online, about two-thirds of the parents said they’re concerned about sexual predators on the Internet, and about half of the parents worry about their children seeing pornography online.

Parents were less concerned about online gambling, video games and bullying, the survey found.

“Parents are quite aware of some online safety risks but seem less aware about others,” Dr. Matthew Davis, director of the poll, said in a news release from the University of Michigan Health System. “We know from other studies that about one in seven children between the ages of 10 and 17 have received sexual solicitation over the Internet, and about one in three children have been exposed to sexually explicit material. So it’s not a surprise that most parents whose kids are online unsupervised are concerned about issues related to sexual predators and pornography. On the other hand, cyberbullying is a very worrisome problem for kids, yet the majority of parents say they are not concerned about it.”

However, more than half of the people who need life-saving drugs are not getting them, according to the 2009 AIDS epidemic update, launched on Tuesday in Shanghai by the World Health Organization and Joint UN Program on HIV/AIDS (UNAIDS).

Cocktails of drugs can control HIV but there is no cure.

UNAIDS executive director Michel Sidibe told Reuters in an interview in Shanghai that advances in HIV prevention and treatment were still very lopsided.

“The major problem we are facing today is inequity. It is very important we don’t continue to have 400,000 babies born with HIV in Africa every year,” Sidibe said.

“That is something that the world can deliver. That is why we are calling for virtual elimination of transmission from mother to child by 2015.”

Teguest Guerma, acting director of WHO’s HIV/AIDS department, told a simultaneous press briefing in Geneva that while more than 4 million people were receiving HIV drugs at the end of 2008, up from 3 million at the end of 2007, many more were going without.

“More than 5 million people need treatment and are not receiving it,” Guerma said.

Speaking later to Reuters, Guerma said second line drugs still cost a minimum of $800 per year in low-income countries.

“It is still very expensive … If (patients) fail in the first line regime, they need to switch to the second. One reason it is not being done is because it is not available and it costs too much. Countries are not purchasing it,” Guerma said.

Overall, however, the epidemic seems to be stabilizing, Paul De Lay, deputy executive director of UNAIDS, said in Geneva.

“The data we are seeing confirm this,” he said. “It is a combination of decreasing deaths, more people therefore living, adding to the total number of infected and decreasing new infections.”

In sub-Saharan Africa, where the scourge of AIDS is most keenly felt, there were 400,000 fewer infections in 2008, or down 15 percent compared to 2001.

New HIV infections declined 25 percent in East Asia and 10 percent in south and southeast Asia within the same timeframe.

However, more needs to be done, Sidibe said.

“The findings also show that prevention programing is often off the mark and that if we do a better job of getting resources and programs to where they will make the most impact, quicker progress can be made and more lives saved,” he said.

The report also revealed that HIV played a significant factor in deaths to women during childbirth. Using South African data, about 50,000 maternal deaths were associated with HIV in 2008.

“AIDS isolation must end … half of all maternal deaths in Botswana and South Africa are due to HIV,” said Sidibe, who also called for an end to discriminatory laws in many countries.

Laws criminalizing homosexuality and prostitution for example end up driving these high-risk groups underground so they are unable to access treatment or services. Ultimately, infections spread into the general population.

From 1999 to 2006, researchers found a sevenfold increase in the incidence of outpatients with methicillin-resistant Staphylococcus aureus (MRSA) infections. Outpatients include people treated in emergency departments or surgical centers but not admitted, or at doctors’ offices associated with hospitals.

This poses a risk to inpatients because many resources are used by both sets of patients. These include surgical centers and the doctors themselves, who often treat patients both inside and outside of hospitals.

“What this is suggesting is that outpatients are a significant source of MRSA, especially community-associated MRSA strains,” said the study’s lead author, Eili Klein, a doctoral candidate at Princeton University and a researcher at Resources for the Future, a Washington, D.C.-based think tank. “This suggests the need for incentives to make sure hospitals are not only taking steps to prevent hospital-associated strains from spreading among inpatients, but preventing the spread of community-associated strains through shared resources.”

The study is published in the December issue of Emerging Infectious Diseases.

MRSA, which burst into the public consciousness in the 1990s, is named for its resistance to methicillin and other antibiotics. There are several strains, including those that emerged in hospitals, called “hospital associated,” and those that emerged outside hospitals and tend to spread in schools and gyms, called “community associated.”

While both types can cause serious, life-threatening illness, hospital-acquired strains are generally more virulent. The bacteria can get into wounds, causing deadly blood or lung infections. About 20,000 people in the United States die each year from the MRSA infections, according to background information in the study.

Community-associated strains have also caused some deaths in otherwise healthy people, including several children who were killed by MRSA infections in the late 1990s. Typically, however, community-associated strains cause skin or other soft tissue infections that are treatable with newer antibiotics.

According to the research, the number of hospital-associated infections remained relatively stable from 1999 to 2003, even decreasing a bit from 2003 to 2005. Some of the reduction was due to better infection-control measures, such as more thorough and frequent hand washing among doctors, Klein said.

Community-associated strains, however, are becoming far more commonplace. Among outpatients with staph infections, MRSA infections increased by more than 90 percent, according to the data culled from 300 microbiology labs serving hospitals across the nation.

Most of the increase was due to community-associated strains, which rose from 3.6 percent of all MRSA infections in 1999 to 28.2 percent in 2006, the study found.

The increases pose a risk to hospital inpatients, who may become infected by contaminated equipment in surgical centers used for inpatients and outpatients or by the doctors themselves.

The study did not find an increase in hospital-associated strains spreading in the community.

After hearing reports of community-associated MRSA strains showing up in hospitals, the U.S. Centers for Disease Control and Prevention analyzed the data it has collected on invasive MRSA infections, said Dr. Fernanda Lessa, a CDC medical epidemiologist.

The CDC report found that the proportion of community-associated MRSA infections in hospitals, compared with MRSA infections overall, remained small and that the infections were no more virulent than those already present.

“So far it hasn’t been a big problem,” Lessa said. “Our data suggested the community-associated strain doesn’t seem to be taking off in hospitals and is not causing worse disease.”

Other research also has shown a rise in community-associated strains. A study in the January issue of Archives of Otolaryngology Head & Neck Surgery found that MRSA infections in the ears, nose or sinuses of children more than doubled from 2001 to 2006, going from 12 percent to 28 percent of head-and-neck area infections.

Dr. Allan Jensen, with the Danish Cancer Society in Copenhagen, and colleagues identified higher uterine cancer risk among women who used follicle-stimulating hormone and human menopausal gonadotropin (hMG) for more than 10 years.

They saw similar risk among women who ever took six or more cycles of clomiphene, an established treatment for women not ovulating normally, or when clomiphene did not work, when women were injected with six or more cycles of human chorionic gonadotropin (hCG).

In each of these scenarios, uterine cancer risk seemed about two times the usual risk, Jensen and colleagues report in the American Journal of Epidemiology.

Even so, “the absolute risk of developing uterine cancer is still not very high,” Jensen emphasized in an email to Reuters Health.

From a group of 54,362 women treated for infertility between 1965 and 1998 and followed for 16 years on average, Jensen’s team compared the use of fertility drugs among 83 who developed uterine cancer and 1,241 of similar age who did not develop cancer of the uterus.

Overall, 51 and 50 percent of the women who did and did not develop uterine cancer, respectively, used fertility drugs. Those with uterine cancer ranged from 28 to 67 years old (50 years on average) when diagnosed.

In analyses that allowed for number of births, the investigators did not find significant differences in uterine cancer risk.

Differences in risk, as noted, became evident in analyses of specific fertility drugs used and the length of use. These risks remained when the investigators further allowed for number of births, use of a single or multiple fertility drugs, causes of infertility, and any history of oral contraceptives.

The researchers are continuing to monitor the study group to more definitively assess ties between fertility drugs and uterine cancer risk.

They caution, however, that any unfavorable effects from fertility drugs need to be balanced against the physical and psychological benefits of pregnancies that may only be possible with the use of fertility drugs.

The U.S. National Library of Medicine offers this list of common causes:
Swallowing air.
Being constipated.
Having too much gas in the bowels.
Having lactose intolerance or other food intolerance.
Eating too much.
Having irritable bowel syndrome (IBS).
Having a partial bowel obstruction.
Having too much bacteria in the bowels.
Having, in rare cases, a tumor.

Having too much body fat causes nearly half the cases of endometrial cancer — a type of cancer of the uterus — and a third of esophageal cancer cases, the American Institute for Cancer Research said.

Cancer is the second-leading cause of death in the United States after heart disease. The American Cancer Society projects that 1.47 million people will be diagnosed with cancer this year and 562,000 will die of it.

More than 26 percent of Americans are obese, defined as having a body mass index of 30 or higher. BMI is equal to weight in kilograms divided by height in meters squared. A person 5 feet 5 inches tall becomes obese at 180 pounds (82 kg).

Additionally, nearly a third of Americans are overweight, defined as having a BMI of 25 to 30.

The study combined findings from AICR research linking diet, physical activity and fatness with cancer risk with national surveys on obesity and cancer incidence.

“We then worked out the percentage of those specific cancers that would be prevented if everyone in the United States maintained a healthy weight,” the group said in a statement.

Here are some of its estimates of cancer types that could be prevented annually if Americans stayed slender:

* Esophageal – 35 percent of cases or 5,800 people

* Pancreatic – 28 percent or 11,900

* Gallbladder – 21 percent or 2,000

* Colon – 9 percent or 13,200

* Breast – 17 percent or 33,000

* Endometrium – 49 percent or 20,700

* Kidney – 24 percent or 13,900

In July, federal and other researchers estimated that obesity-related diseases account for nearly 10 percent of all medical spending in the United States or an estimated $147 billion a year.

They studied the link between phosphorus levels and coronary artery calcification (CAC) in nearly 900 healthy adults in the Spokane Heart Study, a long-term investigation of heart disease risk factors. CAC is an early sign of hardening of the arteries.

At the start of the study, 28 percent of participants had CAC. After six years of follow-up, another 33 percent had developed CAC, and the level of CAC increased among those who already had the condition.

The association between phosphorus levels and CAC was strong even after the researchers adjusted for other factors.

“Even small increases in the blood level of phosphorus predicted an increased risk of progressive CAC in these apparently healthy adults,” Dr. Katherine R. Tuttle, of the Providence Medical Research Center in Spokane, said in a news release.

The researchers also found that people with lower kidney function — even if not below the normal range — were more likely to have progressive CAC.

“Our results may help to explain why even early-stage chronic kidney disease (CKD) is associated with increased cardiovascular risk that is not explained by traditional risk factors,” Tuttle said. “More research will be needed to see if treatments to lower phosphorus levels can reduce heart disease risk in people with early-stage CKD, or even those without CKD who have CAC.”

Also, more than half of drivers surveyed admitted that they’ve driven over the last year while feeling drowsy, and 28 percent said they drive while sleepy at least once a month, according to the survey sponsored by the National Sleep Foundation.

“People underestimate how tired they are and think that they can stay awake by sheer force of will,” Thomas Balkin, chairman of the National Sleep Foundation, said in a news release about the 2009 Sleep in America poll. “This is a risky misconception. Would there be 1.9 million fatigue-related crashes or near misses if people were good at assessing their own ability to drive when fatigued?” he asked.

“The problem is that although we are pretty good at recognizing when we feel sleepy, we do not recognize the process of actually falling asleep as it is happening,” Balkin said. “The process robs us of both self-awareness and awareness of our environment. All it takes is a moment of reduced awareness to cause a crash.”

Research has suggested that not sleeping for more than 20 hours can make people as impaired as if they were drunk. Sleepiness slows reaction times, makes people less aware and impairs their judgment, researchers say.

What do the experts suggest? The National Sleep Foundation recommends that you watch out for these warning signs:
Difficulty focusing, heavy eyelids and difficulty avoiding daydreams
Nodding, forgetting the last few miles you’ve driven, and repeated yawning
Restlessness and irritability

If you do feel sleepy on the road, turn the wheel over to a buddy and take a nap.

Caffeinated beverages or caffeinated gum can keep you more alert for a few hours. You could even drink a caffeinated beverage and take a quick nap — 20 to 30 minutes — before it kicks in.

But remember, caffeine is no replacement for sleep. You’ll still need to get some shuteye.

In the Oct. 5 online issue of the Journal of Clinical Oncology, researchers report that the more acini a woman has — these are the sacs that produce milk — and the larger her breast lobules, the higher the chance she will get breast cancer.

“A tremendous number of women get breast biopsies from abnormal mammograms. They number 1 to 2 million people a year in the U.S. alone,” said study co-author Derek Radisky, an assistant professor of biochemistry at the Mayo Clinic in Jacksonville, Fla. “Of these, about one-quarter have positive findings of cancer while the rest could immediately benefit from this kind of assessment.”

“We have recognized for a long time that the cancer risk-assessment models we have are not perfect, particularly for individual patients, so certainly this is an approach that’s very interesting. But it’s not going to change anything for a woman who walks in the clinic for the next year,” said Dr. Angela Bradbury, director of the Margaret Dyson Family Risk Assessment Program at Fox Chase Cancer Center in Philadelphia. “But it’s exactly this type of paper, this type of research that, two to three years down the road, may actually play out in the clinic. Anything that improves on our risk assessment will be useful.”

Currently, factors such as family history of breast cancer, number of pregnancies and age at first pregnancy are helpful in predicting how often breast cancer will arise in a larger population.

But these same tools are poor indicators of individual risk.

“They’re terrible on an individual basis, so there’s no individualized ability to say whether a person is likely to get cancer or not,” Radisky said.

Other than family history and genetics, the best tool experts have to predict individual breast cancer risk is the Gail model, which takes into account age and number of previous biopsies, as well as family history and pregnancy history.

But, the authors stated, the Gail model is “only slightly better than chance alone.”

This is not the case in cervical or colon cancer, where pathologists can tell from physical characteristics of actual tissue how likely a person is to get that type of cancer.

Breast cancer originates in the breast lobules. The lobules are supposed to disappear as a woman ages, reducing her breast cancer risk, but this doesn’t always happen.

The authors analyzed tissue from 85 women with breast cancer (as well as earlier tissue samples taken before they developed the cancer) and 142 control samples from women who had had benign breast disease.

The more acini per lobule a woman had and the larger the lobule, the higher her risk for developing breast cancer, the researchers found.

This new technique proved more accurate than the Gail model.

The study was a relatively small one by breast cancer standards. More research will not only have to have more women, it will also need to incorporate additional risk factors and will need to be tested in a separate set of women, Radisky said.

Still, he said, the current results “look very good” and he would be “pretty shocked if [more findings] were not consistent.”

If more studies do replicate these initial findings, the procedure might find its way into clinical practice fairly easily and quickly.

“That’s the real power of this. It’s not high tech. It could be done anywhere that takes tissue and has a microscope,” Radisky said. “It could be done anywhere once we build the model, using factors that are available to the physician just from asking the patient and taking tissue, which could be evaluated by any pathologist in any town in America.”
