Are Certain Thin People Actually Obese?
Research suggests that thin people may not be as healthy as they appear.
Medical researchers at Imperial College, London, have shown that people with low or average body weight may not be healthy on the inside. These doctors believe that internal fat surrounding various vital organs could be as detrimental to health as is the more obvious (subcutaneous) fat found directly under the skin. This internal lining of fat is invisible to the naked eye but is detected by MRI machines that create "fat maps" displaying where concentrations of this internal fat are stored.

Potential Exercise Pill
A new study conducted on mice reveals the potential for a drug that can give the same results as exercise.
At the Salk Institute, Dr. Ronald Evans has engineered a drug for mice that chemically stimulates a key receptor known as peroxisome profliferators-activated receptor that controls the ability of cells to burn fat. The PPARd activates a set of genes that coordinates fatty acid oxidation and energy uncoupling which are the same cellular processes that occur from exercise.

Seven years ago, when she was just 53, Judy Fein had a heart attack. But like many women, Judy never even thought about her heart.
Amazingly, neither did her doctor.
“I smoked that was a problem…a lot…a pack and a half a lot!,”
Says Judy.

Lupus Awareness
October is lupus awareness month. It’s a disease that affects predominantly women, and many aren’t aware of it even when they do have it.
Lupus affects perhaps 1.5 million Americans, it hits women compared to men in a 9 to 1 ratio, and it affects the African American population in particular.
The problem: many women—especially those 18 to 24, those most likely to get it-- don’t know anything about this disease, its signs or symptoms.

Migraines and Cardiovascular
They’re painful, they’re debilitating, but could migraines also be deadly?
New research says that at least one in five migraine sufferers, if not more, are at an increased risk of death.
At the age of 35, Hailey McDad is one of them. That’s because she suffers from migraines with aura. “My hands will tingle, my finger tips will tingle, and I see blurry vision, so I know right away I have to medicate myself, so those are my warning signs,” says Hailey.

“Back in 94 I was laying down Christmas Eve and my heart started racing and when I got here my heart rate was 250 beats.” Ronald McClarin has a dangerous heart rhythm--which is why doctors put into him an ICD--an implantable cardioverter. It keeps his heart beating regularly…and shocks it when the rhythm has gone arhy.
But pacemakers and ICDs do fail from time to time.
There are more and more pacemakers and so called ICD’s—implantable cardioverter-defibillators used each year.
Still there is not a lot known about their reliability and how often they malfunction--something that could cause a very serious problem.

Beta Blockers Blasted
A popular class of blood pressure medicines has been for the most part dissed in a major medical journal, prompting questions as to whether patient should switch from the treatment they’re currently taking.
For three decades now, beta-blockers have been an important treatment for high blood pressure. However, there have been several studies that have questioned their effectiveness, and this latest one makes it clear that this once-favorite group of blood pressure medicines is rapidly falling out of favor.

FOOTBALL AND HEAT ILLNESS
With high school and college football season less than a month away, student athletes are back on the practice field toiling away in the august sun. There is great attention this year on the issue of heat illness and even heat-related deaths on the football field. What are coaches doing differently, if anything?
There has already been one heat-related death on a college football practice field this year. The questions is, are players being pushed too hard? Are they being given sufficient access to the liquids their bodies need to literally stay alive in the hot summer sun? No doubt football players are some of the toughest guys you’ll meet, but without the right precautions against heat illness, they are extremely vulnerable to heat-related deaths.
