Children born in areas heavy traffic areas could be at greater risk of developing asthma due to genetic changes brought on by pollution and acquired in the womb, a new study suggests.
In a study of umbilical cord blood from New York City children, researchers found a change in a gene called ACSL3 that is associated with prenatal exposure to chemical pollutants called polycyclic aromatic hydrocarbons (PAHs), which are byproducts of incomplete combustion from carbon-containing fuels, resulting in high levels in heavy-traffic areas.
Exposure to PAHs has previously been linked to diseases such as cancer and childhood asthma.
Researchers say this finding provides a potential clue for predicting environmentally related asthma in children – particularly those born to mothers who live in high-traffic areas like Northern Manhattan and South Bronx when pregnant.
The genetic alterations are called epigenetic changes, which may disrupt the normal functioning of genes by affecting their expression but do not cause structural changes or mutations in the genes.
“Our data support the concept that environmental exposures can interact with genes during key developmental periods to trigger disease onset later in life, and that tissues are being reprogrammed to become abnormal later,” said Shuk-mei Ho, University of Cincinnati researcher and lead author of a paper on the results published in the Feb. 16 issue of the journal PLoS ONE.
The researchers analyzed umbilical cord white blood cell samples from 56 children for epigenetic alterations related to prenatal PAH exposure in Northern Manhattan and the South Bronx. The mothers’ exposure to PAHs was monitored during pregnancy using backpack air monitors.
The researchers found a significant association between changes in ACSL3 methylation – a gene expressed in the lung – and maternal PAH exposure. ACSL3 also was associated with a parental report of asthma symptoms in the children prior to age 5.
“This research is aimed at detecting early signs of asthma risk so that we can better prevent this chronic disease that affects as many as 25 percent of children in Northern Manhattan and elsewhere,” said Frederica Perera, co-author on the paper from Columbia University Mailman School of Public Health.
More research is needed to confirm the findings, the scientists said. If the study is confirmed, changes in the ACSL3 gene could serve as a novel biomarker for early diagnosis of pollution-related asthma.
“Understanding early predictors of asthma is an important area of investigation,” said study team member Rachel Miller of the Columbia Center for Children’s Environmental Health. “because they represent potential clinical targets for intervention.”
The study was funded by the National Institute of Environmental Health Sciences, the U.S. Environmental Protection Agency (EPA) and private foundations.
BEIJING, China (CNN) — A 29-year-old man in southwest China is in critical condition after testing positive for bird flu, making him the country’s sixth confirmed case of the virus this month, state media said Sunday.
Chickens at a market in Kaili, Guizhou province on January 22. China has the world’s largest poultry population.
Chickens at a market in Kaili, Guizhou province on January 22. China has the world’s largest poultry population.
The man fell ill on January 15 in Guizhou province, and tested positive for the H5N1 virus on Sunday, the Xinhua news agency said.
Authorities are monitoring others who came in contact with the man, but no one else has been found ill, Xinhua said.
In recent days, China’s health ministry has moved to allay fears over a bird flu outbreak. The ministry said that although further human bird flu cases were possible throughout China, there wouldn’t be a large-scale outbreak, Xinhua and CCTV said.
The country also announced it was setting up a nationwide network to test for the virus.
On Saturday, health officials said a 31-year-old woman from Xinjiang Uygur Autonomous Region in the far northwest died from the virus. And a 16-year-old boy, who had fallen ill on January 8, died in the city of Huaihua in central Hunan province.
One week ago, a 27-year-old woman from eastern China died of bird flu, and on January 5, a 19-year-old Beijing woman died after handling poultry, officials said.
In addition, the World Health Organization said a two-year-old girl in northern Shanxi province had tested positive for bird flu.
Since the end of 2003, the H5N1 virus has infected numerous species of birds in more than 60 countries in Asia, Europe and Africa.
It has not been found in birds in North or South America or the Caribbean, according to the Food and Agriculture Organization of the United Nations.
Human-to-human transmission of avian flu is rare, but in some cases the virus has passed from poultry to humans. It has killed more than 200 people since 2003.
China reported its first human-to-human infection case in 2005. Of the 34 cases confirmed to date in the country, 23 have been fatal, the World Health Organization said Saturday.
A penile fracture is an extremely rare injury caused by the rupture of the tunica albuginea, which envelops the corpus cavernosum penis. It is an uncommon injury, most often caused by a blunt trauma to an erect penis.
Presentation
A popping or cracking sound, significant pain, immediate flaccidity, and skin hematoma of various sizes are commonly associated with the event. These symptoms are similar to a common bruising or contusion of the penis.
Treatment and prognosis
Penile fracture is a medical emergency, and emergency medical surgical repair is the usual treatment. Delay in seeking treatment increases the complication rate. Non-surgical approaches result in 10%-50% complication rates including erectile dysfunction, permanent penile curvature, damage to the urethra, and pain during sexual intercourse.
Causes
In the western world the most common cause, accounting for about 30%-50% of cases, is intercourse. Of those, woman-on-top positions resulting in impact against the female pelvis or perineum and bending laterally are most common.
MIAMI – D’Zhana Simmons says she felt like a “fake person” for 118 days when she had no heart beating in her chest. “But I know that I really was here,” the 14-year-old said, “and I did live without a heart.”
As she was being released Wednesday from a Miami hospital, the shy teen seemed in awe of what she’s endured. Since July, she’s had two heart transplants and survived with artificial heart pumps – but no heart – for four months between the transplants.
Last spring D’Zhana and her parents learned she had an enlarged heart that was too weak to sufficiently pump blood. They traveled from their home in Clinton, S.C. to Holtz Children’s Hospital in Miami for a heart transplant.
But her new heart didn’t work properly and could have ruptured so surgeons removed it two days later.
And they did something unusual, especially for a young patient: They replaced the heart with a pair of artificial pumping devices that kept blood flowing through her body until she could have a second transplant.
Dr. Peter Wearden, a cardiothoracic surgeon at Children’s Hospital of Pittsburgh who works with the kind of pumps used in this case, said what the Miami medical team managed to do “is a big deal.”
“For (more than) 100 days, there was no heart in this girl’s body? That is pretty amazing,” Wearden said.
The pumps, ventricular assist devices, are typically used with a heart still in place to help the chambers circulate blood. With D’Zhana’s heart removed, doctors at Holtz Children’s Hospital crafted substitute heart chambers using a fabric and connected these to the two pumps.
Although artificial hearts have been approved for adults, none has been federally approved for use in children. In general, there are fewer options for pediatric patients. That’s because it’s rarer for them to have these life-threatening conditions, so companies don’t invest as much into technology that could help them, said Dr. Marco Ricci, director of pediatric cardiac surgery at the University of Miami.
He said this case demonstrates that doctors now have one more option.
“In the past, this situation could have been lethal,” Ricci said.
And it nearly was. During the almost four months between her two transplants, D’Zhana wasn’t able to breathe on her own half the time. She also had kidney and liver failure and gastrointestinal bleeding.
Taking a short stroll – when she felt up for it – required the help of four people, at least one of whom would steer the photocopier-sized machine that was the external part of the pumping devices.
When D’Zhana was stable enough for another operation, doctors did the second transplant on Oct. 29.
“I truly believe it’s a miracle,” said her mother, Twolla Anderson.
D’Zhana said now she’s grateful for small things: She’ll see her five siblings soon, and she can spend time outdoors.
“I’m glad I can walk without the machine,” she said, her turquoise princess top covering most of the scars on her chest. After thanking the surgeons for helping her, D’Zhana began weeping.
Doctors say she’ll be able to do most things that teens do, like attending school and going out with friends. She will be on lifelong medication to keep her body from rejecting the donated heart, and there’s a 50-50 chance she’ll need another transplant before she turns 30.
For now, though, D’Zhana is looking forward to celebrating another milestone. On Saturday, she turns 15 and plans to spend the day riding in a boat off Miami’s coast.

Volumes on personal stereos are likely to be restricted by regulators because of fears that MP3 players and “in-ear” phones are damaging hearing.
Up to a tenth of users are listening to music at levels that could cause permanent hearing loss after five years, an influential scientific commission has found.
Personal music players are allowed to reach 100 decibels. But with “in-ear” headphones the actual sound at the eardrum can reach 120dB.
A report from the European Union’s Scientific Committee on Emerging and Newly Identified Health Risks said that there was a danger from long-term exposure to music pumped into the ears above 89dB.
The committee said that rising numbers of people were plugging themselves into loud music every day for journeys to and from school or work.
It found that MP3 devices were a greater risk to hearing than cassette players because of their ability to reproduce sounds at very high volumes without loss of quality. Last year MP3 devices accounted for 83 per cent of all personal music players sold, and about a fifth of new mobile telephones also feature a digital music player.
The committee said: “In the last few years, leisure noise has become a significant threat to hearing because it can reach very high volumes and because an increasing proportion of the population is exposed to it, particularly young people.”
A British study found that 6.9 per cent of people aged 18 to 25 played their personal stereos louder than 90dB. The Royal National Institute for Deaf People has calculated that more than two thirds of young people who regularly use MP3 players face premature hearing damage.
As well as hearing loss and tinnitus, loud noise can also affect the memory, attention, school performance and may even lead to higher blood pressure, according to some studies.
Apple, which makes the iPod, the most popular personal music player, has already introduced software that allows users to set volume limits, after being ordered to remove them from sale in France. In 2006 an American legal action claimed that Apple had failed to take adequate steps to prevent hearing loss because the iPod could produce up to 115dB.
Personal music players are used daily by up to 100 million people across Europe. Add up the hours and the decibels, and the number in the EU risking permanent hearing loss is put at between 2.5 million and ten million people.
The scientific committee has concluded that the hearing loss is negligible at sound levels below 80dB – a feasible new maximum limit for portable stereos.
The study did not, however, address the other risk to the personal music generation – a thump from their neighbours on trains and in streets from irritating noise “leakage” from their high-volume music.
The commission simply observed: “Environmental sounds to which the general public is exposed – such as noise from traffic, construction, aircraft or from the neighbourhood – can be very irritating but are in most cases not loud enough to harm hearing.”
Meglena Kuneva, the EU Consumer Affairs Commissioner, said: “I am concerned that so many young people, in particular, who are frequent users of personal music players and mobile phones at high acoustic levels, may be unknowingly damaging their hearing irrevocably.
“We need to look again at the controls in place, in the light of this scientific advice, to make sure they are fully effective and keep pace with new technology.”
The European Commission is organising a conference to discuss the findings and is expected to recommend a reduction in the maximum legal volume of portable players.

About 1 in 3 adults has high blood pressure, but many people don’t do a good job of controlling the problem because medications can be pricey. And doctors may not be doing all they can, either. According to new research, released last week during the annual meeting of the American Heart Association’s Council for High Blood Pressure Research, many doctors fail to follow national guidelines that call for treating people above the 120/80 level. Here, then, is an online calculator from the American Heart Association that will help you calculate your risk, as well as five low-cost ways to lower your blood pressure.
1. Take a diuretic. A major study that examined commonly prescribed medications—including ACE-inhibitors, alpha blockers, and calcium channel blockers—found that diuretics, an older class of drugs, were more effective than the others at treating hypertension. You should talk to your doctor before trying a diuretic; most types require a prescription. Thiazide diuretics are an especially affordable and often effective option.
2. Cut back on salt. Again and again researchers have proved that eating too much salt causes blood pressure to rise. The National Heart Lung and Blood Institute suggests that even healthy adults eat no more than 2,400 milligrams of sodium—or about a teaspoon of table salt—a day; people with high blood pressure will want to eat about half of that. Try substituting spices such as bay leaf, nutmeg, pepper, basil, curry powder, garlic, ginger, oregano, and rosemary.
3. Use the DASH diet. The name of this diet—Dietary Approaches to Stop Hypertension—says it all. Research has proven that the DASH diet, which emphasizes fruits, vegetables, whole grains, and low-fat dairy foods, can reduce blood pressure in just 14 days. Wondering how it works? An earlier U.S. News article offers more details about exactly what to eat, as well as a sample menu.
4. Drink less alcohol. If you’re a heavy drinker, cutting back to one or two drinks a day can lower systolic blood pressure by 2 to 4 millimeters of mercury (mm Hg). (Blood pressure readings—110/70, for example—are measured in millimeters of mercury; systolic blood pressure is the top or first number, the maximum pressure exerted when the heart contracts.) In addition, avoiding alcohol can help you avoid unwanted calories and keep your weight down.
5. Exercise. In a recent analysis of more than 50 research trials, regular physical activity reduced blood pressure by an average of 4/3 mm Hg. Other research has shown that every 2.2 pounds of weight loss causes blood pressure to drop by about 1/1 mm Hg. Experts recommend at least 30 minutes on most days of the week.

ISLAMABAD: – A daily dose of vitamin E may help delay the onset of Type 2 diabetes in people at high risk of the disease, preliminary research suggests.
Researchers in New Zealand found that high-dose vitamin E appeared to temporarily improve insulin resistance — a precursor to Type 2 diabetes — among 41 overweight adults.
Though the improvement was short-lived, another diabetes risk factor — elevations in a liver enzyme called alanine transferase — changed for the better throughout the six-month stud.
“These results suggest that vitamin E could have a role to play in delaying the onset of diabetes in at-risk individuals,” Dr. Patrick J. Manning and colleagues at the University of Otago in Dunedin report in the journal Diabetes Care.
Some past studies have reached similar conclusions. A recent study found that people whose diets had a healthy dose of antioxidants, including vitamin E, had a lower diabetes risk than those with lower antioxidant intakes. And vitamin E has been shown to help some diabetics gain better control over their blood sugar.
The new study included 80 overweight adults ages 31 to 65. Overweight and obese individuals are at increased risk of developing insulin resistance, in which the body loses sensitivity to the hormone insulin, causing blood sugar levels to soar.
According to Manning’s team, excess fat may speed the production of oxygen free radicals, potentially cell-damaging byproducts of normal metabolism. Compounding this, overweight people tend to have low levels of antioxidants, which counter the effects of free radicals. It’s hypothesized that the resulting oxidative stress may contribute to insulin resistance.
To see whether vitamin E can alter oxidative stress and insulin resistance, Manning and his colleagues randomly assigned study participants to take either vitamin E or a placebo pill every day for six months. For the first three months, the treatment group took 800 International Units (IU) of vitamin E each day, followed by 1,200 IU per day for the next three months — doses many times the recommended dietary allowance of 22 IU.
The researchers found that at both the three- and six-month marks, plasma peroxides, which are markers of oxidative stress, had fallen in the vitamin E group. After three months, blood sugar levels and insulin sensitivity had also improved, but the gains did not remain through the sixth month.
On the other hand, the researchers found, there was a lasting decline in blood levels of alanine transferase liver enzymes, elevations of which have been tied to a heightened diabetes risk. The liver, the authors note, plays a key role in sugar and insulin metabolism, and is the main site of insulin clearance from the blood.
According to Manning’s team, vitamin E may boost insulin sensitivity and decrease diabetes risk in a number of ways, including by reducing oxidative stress to cells and by improving liver function.
However, the researchers note, it’s unclear why blood sugar levels and insulin resistance improved only temporarily, when markers of oxidative stress and liver function continued to look better. A larger study, they conclude, is needed to clarify the picture.
