Mercury Levels Off the Chart in Some Shark Meat

great_white_shark_670x440

A sharp dietary warning emerged from the Sharks International Conference taking place in Durban, South Africa this week, iol Scitech reported. According to a presenter at the gathering, eating shark meat could kill you.

Southern Cross University researcher Jann Gilbert said that in three species of shark mercury and arsenic levels were found to be well above those considered safe by Australia and New Zealand’s Food Standards Authority.

Gilbert examined shark meat samples from great white, sandbar and dusky species and found toxic metals in all three. Mercury levels alone were 10 times above safe levels in two of the species, she reported.download

How do sharks come by such quantities of the toxic material? According to Kady Lyons, from the University of Calgary, it’s thanks to sharks being top-of-the-food-chain creatures that eat widely of whatever appeals to them, accumulating and spreading the toxins along the way.

If sharks feed too close to coastlines of large cities or places where there is lots of agricultural waste, they’ll pick up the toxins from their prey. Mother sharks will even pass on chemicals such as DDT to their babies through their fatty tissue.

Hundreds of millions of sharks are killed each year for food consumption. Gilbert cautioned against eating sharks longer than 5 feet and warned that pregnant women should protect their babies in the womb by not consuming shark meat more frequently than every two weeks.

China official suggests ‘biting pencils’ to blame for child lead poisoning

china-official-suggests-biting-pencils-not-nearby-chemical-plant--to-blame-for-child-lead-poisoning

A Chinese official has suggested the biting of pencils as a possible explanation for excessive levels of lead found in children in a town in the south of the country located next to a chemical plant, state media reported on Monday.

The plant, in Dapu in the southern province of Hunan, has been shut down after tests found that more than 300 children had excessive levels of lead in their blood, the Global Times, published by the ruling Communist Party’s official People’s Daily, said.

Su Genlin, head of the Dapu government, said the children could have been made sick by “biting pencils”, the newspaper reported, despite the fact that the “lead” in pencils is graphite.

The government has now announced a probe into both the owner of the chemical plant and local environmental protection agency, the report added.

Chinese media frequently report on similar cases in a country where breakneck economic growth has come at a terrible price for the natural environment in many places.

In 2009, a smelter was closed after it was blamed for the lead poisoning of almost 1,000 children in the northern province of Shaanxi.

Despite repeated pledges to get tough, the government faces an uphill struggle in poorer parts of the country where local authorities often rely on tax receipts from heavily polluting industry.

Artificial Pancreas Shows Promise in Diabetes Test

Artificial Pancreas

A portable artificial pancreas built with a modified iPhone successfully regulated blood sugar levels in a trial with people who have Type 1 diabetes, researchers reported Sunday.

Type 1 diabetes, which usually starts in childhood or young adulthood, is a chronic condition in which the pancreas produces little or no insulin, the hormone that lowers blood sugar levels. Insulin works in conjunction with glucagon, a hormone that raises blood sugar. Together, they keep blood sugar in a healthy range.

Currently about one-third of people with Type 1 diabetes rely on insulin pumps to regulate blood sugar. They eliminate the need for injections and can be programmed to mimic the natural release of insulin by dispensing small doses regularly.

But these pumps do not automatically adjust to the patient’s variable insulin needs, and they do not dispense glucagon. The new device, described in a report in The New England Journal of Medicine, dispenses both hormones, and it does so with little intervention from the patient.

“The data address some of the most difficult problems in diabetes management,” said Dr. Kevan Herold, director of the Yale Diabetes Center, who was not involved in the study. “I’d say that the effects are quite significant and noteworthy.”

Dr. Fredric E. Wondisford, director of the diabetes institute at Johns Hopkins, also found the results encouraging. “To me, it’s a clear advance,” he said. But he cautioned that the effectiveness and practicality of the device had still not been tested in large numbers of patients over long periods of time. He also raised the issue of cost and insurance coverage.

Treatment of Type 1 diabetes is complicated. Patients not using pumps need two or more insulin injections a day, and all have to monitor blood sugar several times a day by pricking their skin and testing their blood.

Maintaining safe blood sugar levels requires precise adjustments, especially to prevent hypoglycemia, or extremely low blood sugar. Hypoglycemia can occur quickly, without the patient’s awareness, and can be a life-threatening emergency.

For patients with adequate treatment, elevated blood sugar is usually not an emergency, but can cause vascular damage over time that can lead to eye problems and amputations.

The artificial pancreas is the latest version of a device that researchers have been refining for several years. The system consists of an iPhone 4S with an attached glucose monitoring device, two pumps, and reservoirs for insulin and glucagon.

A sensor implanted under the skin on one side of the patient’s abdomen measures the glucose in the fluid between the cells, which corresponds closely to blood glucose levels. The sensor delivers the reading to the smartphone, and the phone’s software calculates a dose of insulin and glucagon every five minutes.

The medicine is then pumped through thin tubes to two tiny infusion points embedded just under the skin on the other side of the patient’s abdomen.

The phone also has an app with which a patient can enter information immediately before eating, indicating whether the meal is breakfast, lunch or dinner, and whether the carbohydrate content will be small, large or typical. The device then calculates and dispenses the proper dosages.

Continue reading the main storyContinue reading the main storyContinue reading the main story
The device still requires a finger stick twice a day to get an accurate blood reading, which the patient enters into the phone.

The developers tested the device over five days in two groups of patients, 20 adults and 32 adolescents, comparing the results with readings obtained with conventional insulin pumps that the participants were using.

The adults in the trial each had the constant attention of a nurse, and they lived in a hotel for the five-day study. Most of the time they were free to travel around and pursue normal activities.

The adolescents, 16 boys and 16 girls, lived under supervision in a summer camp for youths with diabetes.

“We need to do a true home-use study, give people the device and send them home,” said the lead author, Dr. Steven J. Russell, an assistant professor of medicine at Massachusetts General Hospital. “Let them do whatever it is they’re going to do without supervision.”

Several authors of the new report have received payments from medical device companies and hold patents on blood sugar monitoring technology.

The artificial pancreas performed better than the conventional pump on several measures. Among the adolescents, the average number of interventions for hypoglycemia was 0.8 a day with the experimental pump, compared with 1.6 a day with the insulin pumps. Among adults, the device significantly reduced the amount of time that glucose levels fell too low.

And the artificial pancreas worked well at calculating mealtime doses without the patient having to use (often inaccurate) estimates and correct a too high or too low reading after eating.

Much more work needs to be done before the device can be marketed, Dr. Russell said. The senior author, Edward R. Damiano, an associate professor of biomechanical engineering at Boston University, has a 15-year-old son with Type 1 diabetes. He said he was determined to get the new device working and approved in time for his son to go off to college carrying one.

6 Snack Habits for Healthy Weight Loss

6 Snack Habits

Snacks, finger foods, tapas, amuse-bouche—however you term them, there’s something endlessly satisfying about munching on little hand-held bites of heaven. Problem is, America’s favorite snacks aren’t little; nor are they heavenly.

In fact, a recent study in the journal Hepatology found that 27 percent of kids’ diets come from high-fat, high-sugar snacks, and the frequent grazing is directly linked to belly fat accumulation. Fortunately, there’s also research to suggest we can snack smartly—and slim down.

Here are seven tips that will help you Eat It to Beat It! Snack-tastic!

Watch the clock

Having a bite to hold you over til lunch is common practice, but a study published in the Journal of the American Dietetic Association found that mid-morning snackers tended to snack more throughout the day than afternoon snackers, resulting in hindered weight-loss efforts.

Afternoon snacking was associated with a slightly higher intake of fiber and fruits and vegetables.

Color code your snacks

A recent study suggests you can avoid a mindless binge by adding visual traffic lights to your snack.

Researchers at the University of Pennsylvania and Cornell University gave one set of students a bowl of uniform yellow chips, while another group had their regular snack layered with differently colored chips. Students who had their snack segmented ate 50 percent less than those with a uniform bowl.

Muscle up your munchies

Make sure your snack contains protein, which requires more energy to burn than carbs or fats and thus keeps you fuller longer.

But don’t take it from me: In a study in the journal Appetite, researchers from the University of Missouri compared the satiety effects of high-, moderate-, and low-protein yogurts on 24- to 28-year-old women, and found Greek yogurt, with the highest protein content, to have the greatest effect.

Swap hands

Want to snack less without going snackless? Try the left-handed diet (or right-handed…)

A study printed in the journal Personality and Social Psychology Bulletin found moviegoers grabbed for less popcorn when doing so with their non-dominant hand.

I tested the hypothesis myself earlier this year with the ABC World News team and came to the same conclusion: Eating with your non-dominant hand makes you think about what you’re doing, and may help you eat less.

Use smaller bowls

Grabbing handfuls from the bag is never a good idea, but munching from a punch bowl won’t do much for weight loss either.

Research in The FASEB Journal suggests that overeating may be associated with the size of our serveware. Participants who were given larger bowls, served and ate 16 percent more than those given smaller bowls. Not only that, the big-bowlers underestimated just how much they were eating by 7 percent!

Take advantage of the visual illusion with belly-friendly bowls or ramekins.

Startup Launches ‘First Wearable Health Record’ for Google Glass

technology-startup-launches-first-wearable-health-record-google-glass-1402641836

Google Inc’s futuristic eyeglasses are finding their way into hospitals and clinics throughout the United States.

To meet the growing demand for Google Glass from physicians, Drchrono, a Mountain View, Calif., based electronic medical record company has developed a new application for the device it claims is the first “wearable health record.”

Sign up for top Technology news delivered direct to your inbox.

Doctors who register for the Drchrono app for Glass can use it to record a consultation or surgery with the patient’s permission. Videos, photos and notes are stored in the patient’s electronic medical record or in Box, a cloud-based storage and collaboration service and can be shared with the patient on request.

Dr. Bill J. Metaxas, a podiatrist based in San Francisco, warned fellow physicians to take precautions before using Glass, such as obtaining patient consent and “locking down security settings.” He also said Glass is no more or less secure than tablet devices such as the iPad, which are routinely used in clinical practices.

Metaxas, who uses Glass in the operating room and in patient consultations, said 99 percent of his patients agree to the gadget, but it is still early days and most of his fellow physicians have yet to adopt the technology. It is primarily used by the “bleeding edge” minority, he added.

Still, Box spokeswoman and former Google Health employee Missy Krasner said she is aware of at least 20 venture-backed startups catering to this niche of physicians. The majority of these Glass apps, including Augmedix and Pristine, are complying with federal regulation that protects privacy, known as HIPAA.

To develop the service, Drchrono worked closely with Box, one of its early investors, and the Google Glass team.

Google Glass was intended for the consumer mass market, but it has been criticized by some for its geeky appearance.But many industry professionals immediately saw value in the hands-free gadget.

First MERS case confirmed in Bangladesh

The+Middle+East+respiratory+syndrome+01

Bangladesh has confirmed the first case of the deadly Middle East Respiratory Syndrome coronavirus (MERS) after a man returned from the US via Abu Dhabi was found afflicted with it.

Mahmudur Rahman, director of Institute of Epidemiology, Disease Control & Research (IEDCR), said Sunday that the man was recuperating in a hospital, bdnews24.com reported.

“We have notified it to the WHO,” he said.

Coronaviruses are a large family of viruses that cause a range of illnesses in humans, from the common cold to the Severe Acute Respiratory Syndrome (SARS).

The virus was first identified in 2012 in Saudi Arabia and has remained a global concern since then.

It has spread to 22 countries, including Bangladesh, from the Middle East.

So far, the WHO recorded 699 cases of MERS with a mortality rate of 30 percent.

Laughing gas for childbirth: The new way to have a pain-free labor?

laughing gas

You may have used nitrous oxide, aka laughing gas, to cope with painful dental procedures, but what you may not know is that laughing gas is now being used to help women cope with labor pain.

In the U.S., laughing gas for labor pain was common practice years ago.Now, more women than ever are exploring their options and making informed choices about childbirth, the pain-relief option is seeing a resurgence— more hospitals and birth centers are making it available to their patients.

But is it safe? And will it really make labor pain-free? Find out the answers to these questions and more.

Why laughing gas?
Nitrous oxide for labor pain was common practice in the U.S. in the 1930s, but as other options like twilight sleep, general anesthesia and later, IV narcotics and epidural became available, nitrous oxide fell out of favor.

Today, in countries like Australia, New Zealand, and the United Kingdom., nitrous oxide is common practice, with up to 80 percent of women using it.

“The interest in it has really caught fire,” said Dr. Michelle Collins, a certified nurse-midwife and director of the nurse-midwifery program at Vanderbilt University School of Nursing in Nashville, Tenn. “Women are demanding more options and if there are safe options, they want them available to them.”

Nearly 30 hospitals and birthing centers in the U.S. currently offer or will soon offer nitrous oxide and every day more are calling to get information about it, Collins said.

Laughing gas is a 50-50 mix of nitrous oxide and oxygen that women inhale the through a mouthpiece. Yet unlike in the dental office where it’s administered continuously, the woman decides when and how often to use the odorless gas.

“It’s considered a fairly weak anesthetic,” said Dr. William Camann, director of obstetric anesthesia at Brigham and Women’s Hospital in Boston, Mass. “Nitrous makes you a little drowsy and takes the edge off things.”

Here’s how it works: At the start of a contraction, you breathe in the gas so at the peak of the contraction, you get the most pain relief. Nitrous wears off within a few breaths of when you stop inhaling, so the effects end with the contraction and is completely eliminated from the body, Camann said.

“The pain relief that women feel is variable,” said Collins said. She noted that some women report that nitrous was all they needed, while others say it simply took the edge off. For some, it doesn’t help at all.

Although nitrous oxide is a drug, it’s a viable option– even for women who want to have a natural birth.

“It can help her get through a contraction in a different way and distance herself from the contraction,” said Jenna LoGiudice, a certified nurse midwife and assistant professor at Fairfield University’s School of Nursing. “It’s not necessarily a pain relief method but it’s helping the woman decrease her anxiety and mentally get through a contraction.”

What are the benefits?
Unlike IV drugs or an epidural, you can stop it at anytime. Plus, it doesn’t slow or halt labor, meaning it doesn’t increase your risk for other interventions, including a C-section, LoGiudice said.

Nitrous oxide can also be used at any time during labor, even later on in the process when an epidural isn’t always an option.

Approximately 35 to 40 percent of women who use nitrous oxide also get an epidural. However, this doesn’t necessarily mean the gas didn’t work. Rather, it can help women delay getting the epidural as their labor progresses and allow the baby to move down further, Collins said.

At Vanderbilt, nitrous oxide is also used when woman are anxious about getting an IV or an epidural, or for painful procedures like the manual removal of the placenta or repair to the perineum after delivery.

What you should know.
About 10 percent of women who use nitrous oxide will experience nausea and vomiting and other common complaints such as feeling lightheaded, dizzy or extreme drowsiness. After many hours of labor, some women also report feeling tired, but just like nausea, it’s hard to tell if it’s due to the nitrous or labor itself, Collins said.

Nitrous oxide doesn’t affect the baby’s heart rate or breathing, and studies show that babies whose mothers used it had similar Apgar scores to those who used other pain relief methods or none at all, according to a recent review in the journal Anesthesia and Analgesia. Yet the same report showed that more research using stronger studies is needed.

What’s more, it’s unclear if there are long-term effects on things like development or IQ, as researchers have yet to look at these areas.

The bottom line: Nitrous oxide may help to decrease your anxiety and pain and make for a better birth experience, but it’s important to arm yourself with information and make the best choice for you and your family. Ultimately, it’s about giving women choices to have the birth they envision.

“It’s empowering women to have control of their labor and their pain relief,” LoGiudice said. “They want to feel in control, as they should be.”

Digital addiction a psychiatric disorder: Experts

digital

Obsession with online gaming was the main manifestation in the past but addiction to social media and video downloading are now the trend

Do you find it difficult to leave your smartphone even for a minute or have cravings to check it without any real purpose? Chances are you have become an addict and need professional help. According to psychiatrists, medical authorities worldwide need to formally recognise addiction to internet and digital devices as a disorder.

“Singaporeans spend an average of 38 minutes per session on Facebook, almost twice as long as Americans,” said a latest study by Experian, a global information services company. According to Adrian Wang, a psychiatrist at the Gleneagles Medical Centre in Singapore, digital addiction should now be classified as a psychiatric disorder.

“Patients come for stress anxiety-related problems but their coping mechanism is to go online, go on to social media,” Wang was quoted as saying in a South China Morning Post report. Obsession with online gaming was the main manifestation in the past but addiction to social media and video downloading are now the trend.
In terms of physical symptoms, more people, especially young, are reporting “text neck” or “iNeck” pain. “Many people have their heads lowered and are now using their mobile devices constantly on the go while queuing or even crossing the roads, leading to neck pain,” psychiatrists said.

They define digital addiction by symptoms like inability to control craving, anxiety when separated from a smartphone, loss in productivity in studies or at work and the need to constantly check one’s phone.
