Researchers used functional (“real time”) MRI to observe the brain activity of 12 overweight or obese men during the crucial four hours after they ate a meal, a period that experts say influences eating behavior during the next meal.

The participants’ blood sugar levels and hunger were also measured during this time.

The men’s “meals” were two milkshakes that had the same calories, taste and sweetness. The only difference was that one milkshake contained high-glycemic lam sao de tang can  index carbohydrates and the other had low-glycemic index carbohydrates.

High-glycemic index carbohydrates — which are quickly transformed into sugar in the blood — are found in highly processed foods such as white bread and white rice. Low-glycemic index carbohydrates are found in items such as whole wheat products and sweet potatoes.

The researchers found that consuming carbohydrates like those found in processed foods can cause excess hunger and stimulate areas of the brain involved in reward and cravings, regions that also play a role in addiction, according to the study published June 26 in the American phuong phap tang can hieu qua Journal of Clinical Nutrition.

The study might have implications for weight control, the researchers said.

“Limiting high-glycemic index carbohydrates like white bread and potatoes could help obese individuals reduce cravings and control the urge to overeat,” study leader Dr. David Ludwig, director of the obesity prevention center at Boston Children’s Hospital, said in a hospital news release.

A new type of vaccine may stop the autoimmune attack that occurs in people with type 1 diabetes, researchers report.

Although an initial trial of the vaccine wasn’t able to free anyone from their daily insulin injections, it did boost insulin production, which could help prevent some of type 1 diabetes’ most devastating complications.

Instead of increasing the immune system’s activity like the polio or influenza vaccine does, the new vaccine turns off a portion of the immune response, acting as a huong dan tang can an toan  reverse vaccine. The researchers were able to isolate a part of the immune response that only seems to be involved with type 1 diabetes, according to the study. That means the vaccine likely wouldn’t have the risks that medications that suppress the immune system do.

“We were able to destroy the rogue cells that are attacking the insulin-producing cells without destroying any other part of the immune system, and that’s truly exciting,” said senior study author Dr. Lawrence Steinman, a professor of pediatrics and neurology and neurological sciences at Stanford University School of Medicine.

“Once the immune attack is stopped, I believe there’s great potential for recovery in the beta cells,” Steinman added.

Beta cells in the pancreas produce the hormone giam can nhanh hieu qua voi nam lim xanh insulin. In people with type 1 diabetes, it’s believed that the immune system mistakenly destroys the healthy beta cells, leaving the person with no or too little insulin.

Insulin is a crucial hormone because it’s involved in the metabolism of the carbohydrates. It allows the glucose (sugar) from those carbohydrates to fuel the cells in the body and brain. Without enough insulin, a person will die. That’s why people with type 1 diabetes must take multiple daily injections of insulin, or deliver insulin through a catheter inserted under the skin that’s attached to an insulin pump.

The vaccine was designed by changing a piece of immune-system DNA so that it would shut down the immune system’s response to signals in the body that have previously triggered the mistaken destruction of beta cells. These signals come from fragments of a protein (peptides) called proinsulin, which is found on the surface of beta cells. Proinsulin is a precursor to insulin.

“We just wanted to throw the off switch for the one cell being attacked,” Steinman explained.

The researchers recruited 80 volunteers diagnosed with type 1 diabetes during the past five years. They were randomly placed in one of five groups. Four groups received various doses of the vaccine, and the fifth group received placebo injections. Shots were given weekly for 12 weeks.

No one in the study was able to stop using insulin. nam lim xanh chua benh tai bien mach mau nao “That’s a possible goal, but it’s too early to start saying cure,” Steinman noted.

It’s difficult to measure insulin levels, because they can vary rapidly and dramatically. Instead, researchers measured an increase of a substance called C-peptide, a part of proinsulin that stays in the body longer than insulin. C-peptide levels are used as measure of insulin production.

C-peptide levels improved at all doses of the vaccine compared to the placebo, according to the study. And, it’s believed that higher levels of C-peptide may be related to a reduction in some of the serious complications associated with type 1 diabetes, such as eye disease, kidney problems and heart disease.

No serious adverse events occurred during the trial.

Dr. Richard Insel, chief scientific officer at JDRF (formerly the Juvenile Diabetes Research Foundation), said, “The encouraging results from this initial trial … in established type 1 diabetes not only demonstrated safety, evidence during the vaccine dosing period showed preservation of beta cell function, a decrease in detectable immune cells [that likely attack the beta cells], and a relationship between the two.”

He added that further clinical trials will be needed to figure out the optimal dose for vaccine efficacy and safety.

The study was funded by Bayhill Therapeutics, noi ban nam lim xanh tai hcm which helped to develop the vaccine. The JDRF provided funding for the trial, as did the Iacocca Family Foundation.

Steinman said it’s too soon to know how the vaccine might work in the real world. It’s not clear how often someone would need to be given the vaccine, and how well the body might recover its ability to produce insulin once the autoimmune attack has stopped. It’s also not clear if the vaccine might be more effective in people who’ve recently developed the disease, or in people who have a high risk of developing type 1 diabetes.

Steinman said he hopes to have the next trial under way in a year or so.

The study appeared online June 26 in the journal Science Translational Medicine.

Dr. Joel Zonszein, director of the clinical diabetes center at Montefiore Medical Center in New York City, expressed more caution about the vaccine. “The immune response in type 1 diabetes is very complex, and we’ve been burned many times with the idea of a vaccine for type 1 diabetes,” he noted.

“Because this is a new technology — a DNA-based vaccine — I think it would have to be approved for use in something like advanced cancer first, because it may do good things and bad things.,” Zonszein said. “We don’t know, so we don’t want to give it to otherwise healthy people with type 1 diabetes until we know what the potential for harm is.”

Still, he said that the new vaccine is an exciting discovery. “This is a welcome discovery. It helps us to understand the immune process better,” he said.

The study was done to evaluate more closely the effect of the hormone treatment on women during the years menopause typically begins.

An earlier study, the Women’s Health Initiative Memory Study, found that the hormone treatment produced deficits in thinking ability when given to women 65 years old and older. And other WHI research has found that hormone therapy can increase the risk of breast cancer, heart disease and stroke but protect against osteoporosis, the brittle bone disease.

Based on that research, many experts now suggest that the hormone therapy be taken, if needed, to relieve menopausal symptoms on a short-term tao spirulina basis.

In the new study, the focus was on women who begin hormone therapy between ages 50 and 55, the time period during which menopause typically begins, and evaluate the effect on thinking skills.

“We found no long-term harm on cognition when these drugs were prescribed when women were 50 to 55,” said Mark Espeland, a professor of public health sciences at Wake Forest School of Medicine in Winston-Salem, N.C.

The study was published online June 24 in the journal JAMA Internal Medicine.

Espeland and his team compared women who were given either combination estrogen and progesterone treatment or estrogen alone (which is given in women who have had a hysterectomy). About half of the more than 1,300 women assessed were randomly assigned to take hormone therapy, while the other half were on placebo therapy.

During the follow-up period of about seven years, the women took tests of memory, verbal fluency and other skills during telephone interviews. Nearly 1,200 completed the  tao mat troi spirulina second and final assessment.

Overall, Espeland said, no sustained benefit or risk to brain functioning was found. Test scores of the women on hormone therapy were similar to the scores of those on placebo. For women on estrogen alone, verbal fluency was affected, he said, but that may be a chance finding.

Deciding whether to prescribe hormone therapy always involves weighing benefits and risks, said Dr. Jennifer Leighdon Wu, a gynecologists at Lenox Hill Hospital in New York City. She was not involved in the study but reviewed the findings.

“For women 50 to 55, we can probably  tao mat troi giup giam can take cognition out of the equation when weighing risks and benefits,” Wu said. “In the past, we used to think hormones would keep brains young and [help women] continue to have better brain function,” she said. However, later research disputed that thinking.

Now, Wu said, the new research suggests that for women aged 50 to 55, hormone therapy “is not going to preserve or worsen cognition.”

The bottom line? Preserving memory and other thinking skills, Wu said, “is not a reason to start hormone therapy or avoid hormone therapy.”

Francine Grodstein, associate professor of medicine at Brigham and Women’s Hospital and Harvard Medical School, who wrote a commentary accompanying the study, said, “I think the primary message here is reassurance.”

It probably won’t be the last study to examine the issue, Grodstein said. Even so, she said, “To me the most important finding of this study is to reassure younger women if they need to take hormone therapy to treat

menopausal symptoms there is no obvious harm to uong tao mat troi tu nhien brain health.”

The study was primarily supported by the U.S. National Institute on Aging. One researcher reported research grants to her institution from a variety of pharmaceutical makers.

It’s a sweet treat, but too much of a certain type of honey triggered a dangerous irregular heartbeat in a Turkish father and son, according to a new report.

So-called “mad honey poisoning” is very rare but can happen, experts say. In this case, the pair consumed too much honey made from the pollen of rhododendrons, which can cause heart rhythm problems.

The case involved a 68-year-old man and his 27-year-old son in Turkey who were admitted to a hospital emergency department at the same time with symptoms of nam lim xanh chua benh gi vomiting and dizziness. Doctors determined that both of them had heart rhythm problems.

Both men reported that their breakfasts over the previous three days had included large amounts of honey from the Black Sea region of Turkey. This led doctors to consider that the men could be suffering from “mad honey poisoning.”

The condition can occur after people eat honey contaminated with grayanotoxin, a chemical contained in nectar from the Rhododendron species ponticum and luteum. Grayanotoxin has a harmful effect on the heart.

Mad honey poisoning typically lasts no more than 24 hours. The symptoms of the two men in the study resolved without the need for any medications. An analysis of the honey they consumed showed that it did contain pollen from the two Rhododendron species.

The study was to be presented Tuesday at the annual nam lim xanh chua benh gout meeting of the European Society of Cardiology in Athens, Greece.

Mad honey poisoning occurs most frequently in people who have consumed honey from the Black Sea region of Turkey, a major beekeeping area that is also the native habitat of Rhododendron ponticum and luteum.

However, the possibility of mad honey poisoning should always be considered in any previously healthy person who arrives at hospital with unexplained heart rhythm problems, said study author Dr. Ugur Turk, of Central Hospital in Izmir, Turkey.

“The dissemination of honey around the world means that physicians anywhere may be faced with honey poisoning,” Turk said in a cardiology society news release. He said that anyone who buys honey from Turkey should first consume a small amount and leave it a chua benh tieu duong voi nam lim xanh few days before eating any more in order to determine if they experience any problems.

None of it has been pretty. Much of it has been pricey.  Some of it has been downright painful, such as when we ended up paying out of pocket for nearly $100,000 of medical and mental health care for a family member because our insurance company decided an eating disorder wasn’t life threatening (even though the doctors said it was).

Because of my health insurance dramas, I’ve been eager to see how President Obama’s Affordable Care Act (ACA), also called ObamaCare, will affect families’ lives and health insurance experiences. I’ve done some research, and here are a few ways I think the ACA may rock your world in 2014 (if it hasn’t started rocking it already).

1. You won’t be the victim anymore.

I don’t know about you, but I always felt like my health insurance company was purposely torturing me. The forms were incomprehensible, trying to figure out (let alone appeal) a claim was impossibly complicated, and I felt like no one was on my side in a very out-of-control, precarious experience.

The ACA changes some of that. It began with a Patient’s Bill of Rights presented in 2010 that outlined all of the ways your insurance company could no longer giam can voi tao mat troi mess with you, from raising your premiums without notice to throwing roadblocks into the appeals process. Some of these changes have been rolling out for a few years now, but with 2014 being a pivotal year for the ACA (see an Obamacare phase-in timeline here), taking charge of your own insurance and your own healthcare is going to be getting a lot more attention. Reviewing your bill of rights is a good start.

2. You can’t be turned down for health insurance.

Since 2010, children age 19 and under couldn’t be denied health insurance because of a preexisting condition. Starting in 2014, the same goes for everybody else. That means if you are obese, have delivered a child (yes, some insurers called that a preexisting condition), or have high triglycerides, asthma, anorexia, cancer, ADHD, schizophrenia, diabetes—you name it—you can’t be discriminated against when it comes to receiving health insurance.

No impossible-to-read small-print riders can be attached to your policy that basically prevent you from being insured for the very thing you most need to be insured for.

3. If you don’t have insurance through an employer, finding affordable insurance will be easier.

Everyone will have to have insurance under the new law or pay a penalty. Open enrollment starts in October 2013, with coverage starting January 2014. You’ll be able to shop around to find the plan that’s right for you via health insurance marketplaces, also called exchanges. States got to choose if they wanted to run their own exchanges; if they chose not to, the federal government will run your state exchange (see the list of state exchanges in this PDF). Whether run by your state or the federal government, the exchange will establish a set of competitive rules aimed at getting you a plan that covers the Essential Health Benefits the government requires at the lowest cost. Not all of the plans out there will be able to sell on the exchange. The plans have to compete to get a spot.

You’ll also use the exchanges to apply for any federal subsidies or tax credits you’re eligible for either because you don’t have access to insurance through a job or because your income is at or below poverty level. These exchanges give you more bargaining power than you’ve had before in the insurance shopping biz. Keep in mind, what you pay for health insurance will bi quyet lam dep da still depend on your location, your family size, and (in some states) whether or not you smoke (see #7).

4. You’re less likely to go bankrupt because of medical bills not covered by insurance.

Right now, insurance plans can no longer limit how much they pay out to you for medical care during your lifetime. There are no maximums. Starting in 2014, there won’t be any dollar limits on what insurance plans will pay for your medical care during a single year, either. That will be a financial lifesaver for an individual or family who has a devastating and expensive health crisis occur within a calendar year.

5. If you work for a small business, they may have to offer you health insurance.

If your employer has more than 50 fulltime employees, the new law requires them to offer employees health insurance in 2014—or they’ll have to pay a penalty per employee. The good news for small businesses under 100 employees is that the company can use the state health exchanges to shop for insurance for their employees, which should help it get the kind of bargaining power that larger companies get because of their size.

Even if your employer has fewer than 50 employers, it can choose to offer insurance to its employees. The ACA has established subsidies and tax breaks to help businesses offset the cost of insurance. Read more small business info here.

6. You’re really going to have to remember to floss.

Dental care for adults is not covered under the Affordable Care Act (pediatric dental care is). Since the link between oral health and general health is well researched (heart disease, erectile dysfunction), the pressure is on you to keep those pearly whites sparkling.

The good news is you’ll be able to get your own supplemental dental insurance through the health insurance exchanges, and because of the collective buying power offered by the exchanges it might even be less expensive than what those seeking private dental insurance had to pay before. If you have kids, you might get a supplemental family dental plan and apply the pediatric cach tri benh tieu duong federal subsidies for the children’s part of the premium cost.

7. You’re still going to want to quit smoking.

Of course, you know smoking hurts your health in numerous ways, from aging your skin to damaging your heart. After 2014, it could also hurt your pocketbook even more. The ACA allows states to charge smokers up to 50% more for a health insurance plan. This could make “affordable” health insurance pretty darn pricey, some critics say. And it prevents smokers from the very health plans that give them access to the nicotine patches and smoking-cessation programs that help them quit.

That’s why some states, including Massachusetts, Vermont, Rhode Island, and the District of Columbia have decided not to charge smokers more. California’s legislature is debating such a provision. Still, it makes quitting before 2014 look even better, doesn’t it?

Experts say a lack of awareness of the signs of type 1 diabetes is all too common. Just this month, a Wisconsin toddler died apparently because of undiagnosed type 1 diabetes.

“Addie had flu symptoms,” recalled her mother, Micki Parker, who works in the operating room at a nearby hospital but was unfamiliar with type 1 diabetes.

“By the next morning, she was throwing up every hour,” Parker said. Addie didn’t have a fever, but later that day, she couldn’t get up from the bathroom floor because nguon goc nam lim xanh she was so dizzy.

Eventually, the Parkers learned that Addie’s blood sugar level was 543 milligrams per deciliter (mg/dL) — more than four times higher than normal, according to the American Diabetes Association.

Most people have heard of type 2 diabetes, but type 1 diabetes is far less common. It can strike at any age — even though it used to be known as juvenile diabetes — and it always requires treatment with injected insulin or insulin delivered through a pump. People with type 1 diabetes don’t produce insulin, a hormone needed to convert the food you eat into fuel for the body. Without insulin, glucose (blood sugar) rises to unhealthy levels.

Untreated, type 1 diabetes causes serious complications and even death. But it’s often mistaken for other illnesses — even by doctors.

“There’s an underawareness of type 1 diabetes in the public, and in nam lim xanh tu nhien the healthcare system,” said Dr. Richard Insel, chief scientific officer for JDRF (formerly the Juvenile Diabetes Research Foundation). “Missed diagnoses even occur in emergency rooms; people don’t always think of it.”

Every day, about 80 Americans are diagnosed with type 1 diabetes, and the total number rose 23 percent between 2000 and 2009 in children under 20. Currently, about 3 million Americans — most of them adults — are living with type 1 diabetes, according to the JDRF.

One of them is 20-year-old Amanda Di Lella, who was 13 when she knew something was seriously wrong.

“I was losing weight, but I was always hungry. I was always tired. My symptoms weren’t extreme at first, but they quickly got worse,” she said. “I went from being tired to not being able to get out of bed, from being thirsty to drinking 10 bottles of water in the middle of the night. I had lost 15 pounds, and only weighed 75 pounds when I begged my mother to take me to the doctor.”

Her pediatrician told her mother that Di Lella probably had an eating disorder and he prescribed protein shakes.

Within a few days Di Lella wasn’t waking up. Her mother took her to the hospital, at about the same time the doctor got blood work back showing that she had type 1 diabetes.

Her blood sugar level was over 400, and she was nam lim xanh moc o dau in diabetic ketoacidosis, or DKA. When your body doesn’t get the glucose it needs for fuel (and when there’s no insulin, glucose doesn’t get into the body’s cells), it burns fats for energy. This produces an acidic substance called ketones, which can build up in the blood, causing DKA.

“Once you’re in DKA, you’re set up for some major complications, and approximately 30 percent of people diagnosed with type 1 diabetes still present with DKA,” Insel said.

After a week in the intensive care unit, Di Lella recovered. Her doctor apologized for the error and said he had never had a case of type 1 diabetes, so it wasn’t something he normally looked for.

Insel said it’s important to compare a child’s changes in behavior to the other children in the family. Is the child drinking excessively compared to a sibling? Is a child who has mastered nighttime bladder control suddenly wetting the bed again?

The good news is that it’s easy to test for type 1 diabetes. A urine test can detect whether there’s sugar in the blood. If that test is positive, then a simple test drawing a drop of blood from the fingertip can confirm whether you have diabetes.

Di Lella, now a student at the University of Florida, said she would advise others to “not ignore symptoms that seem so basic. Even small symptoms can be a sign of something much bigger.”

Parker said she wants other parents to know that a child with type 1 diabetes “doesn’t necessarily look sick. Trust your gut instinct, and push to have your child tested.”
