That America has a weight problem can’t be denied, but the social perception that obese people simply can’t lose weight is not true, a new study finds. According to researchers from the Beth Israel Deaconess Medical Center and Harvard Medical School in Boston, obese Americans are trying to lose weight — and many are successful. The researchers looked at data for 4,021 obese people ages 20 and older wh... (read more)
A large international consortium study has found at least two gene variants that increase the risk for common childhood obesity. Writing in Nature Genetics on 8 April, the researchers describe how they linked variants near the loci OLFM4 and HOXB5 to this condition, and showed they are also linked with increased body mass index (BMI) in adults. Lead investigator Dr Struan F.A. Grant, associate director of the ... (read more)
People who ate chocolate a few times a week or more weighed less than those who rarely indulged, according to a U.S. study involving a thousand people. Researchers said the findings, published in the Archives of Internal Medicine, don't prove that adding a candy bar to your daily diet will help you shed pounds. Nor did the total amount of chocolate consumed have an impact. But the researchers, led by Beatrice ... (read more)
When roasted at 475 degrees, coffee beans are sometimes described as rich and full-bodied. But for the full-bodied person who is not so rich, unroasted coffee beans — green as the day they were picked — may hold the key to cheap and effective weight loss, new research suggests. In a study presented Tuesday at the American Chemical Society's spring national meeting in San Diego, 16 overweight young adult... (read more)
People who eat chocolate regularly tend to be thinner, new research suggests. The findings come from a study of nearly 1,000 US people that looked at diet, calorie intake and body mass index (BMI) - a measure of obesity. It found those who ate chocolate a few times a week were, on average, slimmer than those who ate it occasionally. Even though chocolate is loaded with calories, it contains ingredients that may f...

Active video games are often touted as ways to help kids be more physically active—but don’t toss the basketball and jump rope just yet. A study finds that having active video games in the home may not translate into more exercise. The study, released Monday in the journal Pediatrics, tested video games among 78 children ages 9 to 12 with a body mass index between the 50th and the 99th perce... (read more)
The common practice of inserting a stent to repair a narrowed artery has no benefit over standard medical care in treating stable coronary artery disease, according to a new review of randomized controlled trials published on Monday. Stable coronary artery disease is the type of heart ailment that causes angina, or chest pain, after physical exercise or emotional stress but generally not at... (read more)
Gluten-free products are all the rage these days, but many health-conscious eaters who buy them may be wasting their money, the authors of a new commentary in Annals of Internal Medicine suggest. Going gluten-free is necessary for people with celiac disease, an autoimmune condition triggered by gluten, which is found in wheat, barley and rye. The disease causes inflammation in the small intestine and can lead ... (read more)
Fewer women than men suffering from a heart attack appear to experience chest pain symptoms, according to a study of more than one million people in the US. Overall men have significantly more heart attacks, but under the age of 55 women are more likely to die from one. Without displaying the classic chest pain symptoms of a heart attack, researchers say some women may not be getting the right kind of treatment. ... (read more)
With Valentine's day upon us, I figured it would be cliche and expected to write about something related to the heart... and that's exactly what I'm about to do. So, put down your chocolates for a minute and get your learning cap on! Let's start with some basic setup. The heart is pretty important. There are a lot of vessels called arteries that come off of the heart. These arteries supply the body wit... (read more)
Hi, everybody! Thanks for checking out my healthnoise.com profile. When I left my job in finance to go to medical school, I quickly learned that medicine is its own separate universe, and has its own language, culture and economy. Patients and even medical students often have no clue as to what doctors are talking about, and why they do what they do. I’m planning to discuss some topics on healthnoise.com that might help to get us all on th... (read more)
A new study by psychologists at The University of Nottingham has shown that babies who are weaned using solid finger food are more likely to develop healthier food preferences and are less likely to become overweight as children than those who are spoon-fed pureed food. The research just published by BMJ Open set out to examine the impact of weaning style on food preferences and Body Mass... (read more)
Scientists have for the first time improved memory by applying direct electrical stimulation to a key area in the brain as it learns its way around a new environment. The stimulation, delivered through electrodes inserted into the brains of epilepsy patients being prepared for surgery, sharply improved performance on a virtual driving game that tests spatial memory, the neural mapping ability th...

Everyone knows that it can feel really good to get a massage. Now scientists may have figured out why, by identifying how massage switches genes on and off, thus reducing inflammation and coaxing muscle adaptation to exercise. The discovery provides strong evidence that massage merits further study as a treatment for injuries and chronic disorders, said Dr. Mark Tarnopolsky, a researcher at McMaster Un... (read more)
It inspires confidence when a dentist has good teeth, or a hairstylist has a chic ‘do, or when the salesperson at a boutique has an immaculate sense of personal style. The same may be true of doctors who maintain a healthy weight — which may help explain why those who are overweight are less likely to broach the topic of weight loss with their patients. In a study of 500 primary care physicians aro... (read more)
Measuring blood pressure in both arms should be routine because the difference between left and right arm could indicate underlying health problems, says a study review. The Lancet research found that a large difference could mean an increased risk of vascular disease and death. Although existing guidelines state that blood pressure should be measured in both arms, it is not often done. But a heart cha... (read more)
Bioengineers at Tufts University School of Engineering have developed a new silk-based microneedle system able to deliver precise amounts of drugs over time and without need for refrigeration. The tiny needles can be fabricated under normal temperature and pressure and from water, so they can be loaded with sensitive biochemical compounds and maintain their activity prior to use. They are also bi... (read more)
People who enjoy drinking black tea throughout the day may get the added benefit of a slight reduction in their blood pressure, suggests a new Australian study. Although the study cannot identify specific components of the tea that might lead to a drop in blood pressure, the researchers said past studies have shown flavonoids, compounds found in many plants such as tea, are good for heart health. "The mes... (read more)
Fat people have less than thin people. Older people have less than younger people. Men have less than younger women. It is brown fat, actually brown in color, and its great appeal is that it burns calories like a furnace. A new study finds that one form of it, which is turned on when people get cold, sucks fat out of the rest of the body to fuel itself. Another new study finds tha... (read more)
Tiiu Leek's pain began suddenly nearly a decade ago, upending her successful career as a television newscaster for KCLA in Los Angeles.

"It was a two-and-a-half year nightmare," she said. &... (read more)
Autism tends to go hand in hand with a variety of other mental and behavioral conditions in kids, suggests a new study that highlights the fuzzy nature of autism diagnoses themselves. Researchers said that other disorders that often go along with autism -- such as attention-deficit/hyperactivity disorder (ADHD) or learning disabilities -- may complicate the diagnosis, or slow down any improvement in kids who ...

Among weight-loss surgery options, gastric bypass comes with more complications shortly after surgery than gastric banding, but makes up for it with fewer long-term side effects and repeat operations, new research suggests. People who got bypass surgery also lost weight faster, and more kept it off, in the study of more than 400 obese Swiss patients. "What we would like with any of the (weight-loss... (read more)
A team of researchers at the MedUni Vienna's Department of Neurophysiology (Centre for Brain Research) has discovered a previously unknown effect of opioids: the study, which has now been published in the journal Science and was led by Ruth Drdla-Schutting and Jürgen Sandkühler, shows that opioids not only temporarily relieve pain, but at the right dose can also erase memory traces of pain in the spinal cord and therefore...

A medical sign is an objective indication of some medical fact or characteristic that may be detected by a physician during a physical examination of a patient.
Signs may have no meaning for, and can even go unnoticed by, the patient, but may be full of meaning for the healthcare provider, and are often significant in assisting a healthcare provider in diagnosis of medical condition(s) responsible for the patient's symptoms.
