Why Light Make Migraine Worsen?
Disease August 25th, 2009
migraine patients tended to avoid the light to reduce the headaches that are recurrent. Why light conditions worsen migraines?
Migraine is a headache that is felt on one side of the head alone, this disease can even cause the sufferer experiencing nausea.
Scientists from Harvard found the path that is the basis of visual sensitivity to light migraine sufferers. This light can trigger a reaction in a group of active neurons in the brain for some time.
The study, published in the journal Nature Neuroscience, reveal a blind person because of factors of severe migraine degenaratif have the sensitivity to light or fear to be photographed.
Based on observations obtained from the light signal is transmitted from the retina through the optic nerve, but not known with certainty why can exacerbate the pain in the head.
Researchers analyzed 20 migraine sufferers who are blind and divided into 2 groups. The first group is completely blind due to diseases such as cancer or glaucoma, these patients can not see or feel the light image. Whereas the second group suffered blindness due to retinal degenerative diseases, although not able to see the picture but can detect the presence of light.
Patients in both groups experienced increased pain when exposed to light, while the first group did not demonstrate increased severity of pain if exposed to light.
“This shows the involvement of the optic nerve, because the first group of optic nerve does not carry light signals to the brain,” said Professor Rami Burstein, from Beth Israel Deaconess Medical Center in Boston, USA,
Researchers also found a group of retinal cells containing melanopsin photoreceptors (to help control the body’s biological functions, including sleep and wake) are critically involved in this process.
Migraine pain is believed due to the membrane surrounding the brain and central nervous system affected. This stimulates pain receptors and triggers a series of events that leads to prolonged activation of the sensory neurons.
“When the small electrode is inserted into the ‘migraine neurons’, we found that this light can trigger the flow of electrical signals which are assembled in cells. This may help explain why migraine patients the pain improved after a few seconds exposed to light,” said Professor Burstein.
Fitness Cources provoke controversy
Fitness August 15th, 2009
a university in Philadelphia caused controversy by making fitness courses. The students who are overweight are required to follow fitness class that if they want to graduate and get a diploma. Health experts also spoke about the fitness classes.
Parties Lincoln University said that the rule was created due to high rates of obesity and diabetes among these college students, particularly among African-Americans. With this rule, the figure could be reduced and students will have a healthier body.
“At present the problem of obesity has become epidemic, so we felt it necessary to hold the class” said James L. DeBoy of Lincoln’s Department of Health, Physical Education and Recreation.
Tiana Lawson (21 years), one student with excess weight in college, said, “I was on campus to learn. But why should be burdened with such rules if they want to pass?” he said.
Mandate issued by the campus that requires all students tested for Body Mass Index (BMI) to determine whether normal weight or not. Normal BMI value is between 18.5 to 24.9.
For students who value a high BMI, which means that excess body weight, it is obliged to follow a fitness class called the ‘Fitness for Life’ if you want to get a degree from the University.
Classes were taught aerobic fitness and physical activity weight-loss options. And do not forget nutrition counseling, stress and difficulty sleeping.
Mark Rothstein, health experts from the University of Louisville’s School of Medicine, said that the rule is a brilliant idea and great to make students healthier. “But not if it’s the execution and ketidaklulusan threat to students,” said Mark.
But the college says that the class that was one of the courses with the credit system really does not force anyone to lose weight drastically.
“We’re being proactive like this because you want more students to move in a way to attend and participate in this class. If the results of weight at the end of the class will still not match the standard BMI, it’s fine as long as there is a process that way,” said Deboy.
The experts assess health and diet, a fitness class that could endanger the students because they can trigger actions that weight loss is not recommended for passing grades. Besides BMI value can not only be a benchmark to determine whether someone is overweight or not.
“Over the weighted student body can do more physical activity well, that’s no problem. Sports are not the only way to get someone to avoid obesity and diabetes. It is not fair it would have to use this way to make students healthier,” said Marcia Costello from Villanova University.

Not Some Fat People Healthy
Health Care August 13th, 2009
Got body fat (obesity) but was in good health. Better not fall asleep because according to health experts no fat people really healthy, especially in the long run.
Research by experts in Sweden is not to scare or get people desperately dieting. Message was maintaining an ideal weight is not too skinny or fat so that organs in the body does not work too hard.
It could be a fat person feels right now he’s fine, but actually it save problems later on, especially that associated with stroke or a heart.
The conclusion was based on a study that followed more than 1,800 Swedish men between the ages of 30 to 50 years by looking at medical records or death associated with stroke or a heart.
“There’s no fat or obese people who do not will experience health problems. Although it looks fine but later will have difficulty. No fat people who have a healthy metabolism,” said Dr Johan Arnlof from Uppsala University as quoted Health24
Arnlov and colleagues not only study the fat and obesity, but also people with metabolic syndrome.
Metabolic syndrome is a condition someone who had three or more cardiovascular risk factors like high blood pressure, high blood sugar, high fat, low HDL cholesterol and both have a large waist size (men were more than 40 inches (98 cm) and women more than 35 inches (85.75 cm)).
These studies argue that previous studies showed no increased cardiovascular risk in obese men who did not have metabolic syndrome, in other words there are groups of healthy obese people.
But according to the report, it was after 15 years of the study was over, the participants proved to impaired metabolism and cardiovascular health.
“The results were not surprising because it is all the more weight than normal body mass index would be problematic. So there is no reason to say the body fat but healthy,” said Dr Richard A Stein from New York University.
Jamkesmas Insurance
Health Insurance August 7th, 2009
Community Health Insurance (Jamkesmas) which should be directed to poor people has now led to the insurance. Therefore, rather than later Jamkesmas impossible to take premiums from its users.
“This plan is already worked out since the end of 2009 then and still digodog. The bottom line is no discussion had taken care of by the private Jamkesmas,” said Martin.
DKR himself had kissed Jamkesmas be strong indications that uses insurance premiums since the emergence of cases of hospital patients refusing Jamkesmas.
“Now many hospitals are refusing patients with Jamkesmas. The reason for this variety, even one dared put the word ‘Not Receive Jamkesmas To The Left’,” added Martin.
He added that with this condition means that the poor have to pay premiums to a certain amount for health services.
“Cooking community must pay once to get health care? This is obviously not human, and we obviously do not agree. Jamkesmas should still be taken care of government,” said Martin.
