Health Tip: Healing a Broken Collarbone

Monday, March 29th, 2010

Your collarbone, medically called the clavicle, is the bone near the shoulder that helps attach the arm to the body.

The American Academy of Orthopaedic Surgeons says here’s what you can expect during recovery from a broken collarbone:
Wear a sling to keep the arm still for between three and four weeks for children, or as long as six to eight weeks for adults.
Take anti-inflammatory medications, such as ibuprofen or aspirin.
A large bump usually forms on the collarbone, but typically shrinks over time.
You’ll have limited motion and function of the shoulder until the collarbone has healed.
Avoid sports and vigorous exercise until the fracture has healed. With your doctor’s approval, you can begin gentle strengthening exercises once the area is no longer painful.

Adequate sleep tied to healthier diets in truckers

Saturday, March 20th, 2010

Getting plenty of sleep not only helps keep truck drivers safe and alert on the road, it also seems to fuel healthy eating habits, new research hints.

In surveys of truckers working at U.S. trucking terminals, those who felt they regularly got adequate sleep tended to consume more fruits and vegetables and fewer sugary drinks and snacks, Dr. Orfeu M. Buxton, at Harvard Medical School in Boston, Massachusetts, and colleagues found.

These real-world findings are consistent with laboratory studies showing that insufficient sleep increases hunger and “induces greater eating, especially unnecessary snacking,” Buxton noted in an email to Reuters Health.

Buxton and associates assessed self-reported diet, sleep, and job-related factors of 542 male Teamster union members who were 49 years old on average.

Sixty-six percent worked as pick-up and delivery truck drivers, 20 percent as over-the-road truckers, and 15 percent served dual roles as dockworkers and truck drivers, they note in the American Journal of Public Health.

Most of the workers (87 percent) were satisfied with their job and a little more than half (52 percent) said they got enough nightly shuteye “to feel rested upon waking up.”

These well-rested truckers also said they ate an average of about 3 servings of fruits and vegetables (not including French fries), less than one serving of a sugar-added drink, and less than half a serving of a sugary snack daily.

By contrast, truckers reporting insufficient sleep reported eating about two fruit and vegetable servings, and slightly more than one sugary drink and nearly one sugary snack each day.

The investigators conclude that workplace programs to encourage adequate worker sleep may have positive benefits on employee health.

What is CHEAP TADALAFIL used for?

Thursday, March 11th, 2010

Cheap Tadalafil is used to treat men with erectile dysfunction (sometimes called impotence/ ED) when they cannot get, or keep, a hard penis (erection) sufficient for satisfactory sexual activity. For Tadalafil to be effective, sexual stimulation is required.

Contraindications and cautions:
Sexual activity carries a possible risk to patients with heart disease because it puts an extra strain on your heart.
Tadalafil can cause your blood pressure to drop suddenly to an unsafe level if it is taken with certain other medicines. You could get dizzy, faint, or have a heart attack or stroke. Do not take Tadalafil if you:
• take any medicines called “nitrates.”
• use recreational drugs called “poppers” like amyl nitrite and butyl nitrite.
After taking a single tablet, some of the active ingredient of Tadalafil remains in your body for more than 2 days. The active ingredient can remain longer if you have problems with your kidneys or liver, or you are taking certain other medications.
Drinking alcohol may affect your ability to get an erection. Drinking alcohol may temporarily lower your blood pressure. If you have taken or are planning to take Tadalafil, avoid excessive drinking (blood alcohol level of 0.08% or greater), since this may increase the risk of dizziness when standing up.
You should NOT take Tadalafil (CIALIS) more than once a day.

Behavioral Training Improves Connectivity and Function in the Brain

Thursday, March 4th, 2010

Children with poor reading skills who underwent an intensive, six-month training program to improve their reading ability showed increased connectivity in a particular brain region, in addition to making significant gains in reading, according to a study funded in part by the National Institute of Mental Health (NIMH). The study was published in the Dec. 10, 2009, issue of Neuron.

“We have known that behavioral training can enhance brain function.” said NIMH Director Thomas R. Insel, M.D. “The exciting breakthrough here is detecting changes in brain connectivity with behavioral treatment. This finding with reading deficits suggests an exciting new approach to be tested in the treatment of mental disorders, which increasingly appear to be due to problems in specific brain circuits.”

For the study, Timothy Keller, Ph.D., and Marcel Just, Ph.D., both of Carnegie Mellon University, randomly assigned 35 poor readers ages 8–12, to an intensive, remedial reading program, and 12 to a control group that received normal classroom instruction. For comparison, the researchers also included 25 children of similar age who were rated as average or above-average readers by their teachers. The average readers also received only normal classroom instruction.

Four remedial reading programs were offered, but few differences in reading improvements were seen among them. As such, results for participants in these programs were evaluated as a group. All of the programs were given over a six month schooling period, for five days a week in 50-minute sessions (100 hours total), with three students per teacher. The focus of these programs was improving readers’ ability to decode unfamiliar words.

Using a technology called diffusion tensor imaging (DTI), the researchers were able to measure structural properties of the children’s white matter, the insulation-clad fibers that provide efficient communication in the central nervous system. Specifically, DTI shows the movement of water molecules through white matter, reflecting the quality of white matter connections. The better the connection, the more the water molecules move in the same direction, providing a higher “bandwidth” for information transfer between brain regions.

At the outset of the study, poor readers showed lower quality white matter than average readers in a brain region called the anterior left centrum semiovale. Six months later, at the completion of the intensive training, the poor readers showed significant increases in the quality of this region. Children who did not receive the training did not show this increase, suggesting that the changes seen in the remedial training group were not due to natural maturation of the brain.

In an effort to further pinpoint the mechanism underlying this change, the researchers deduced that a process called myelination may be key. Myelin is akin to electrical insulation, allowing for more rapid and efficient communication between nerve cells in the brain. However, the directional association between brain changes and reading improvements remains unclear — whether intensive training brings about increased myelination that results in improved word decoding skills, or whether improved word decoding skills leads to changes in reading habits that result in greater myelination.

“Our findings support not only the positive effects of remediation and rehabilitation for reading disabilities, but may also lead to improved treatments for a range of developmental conditions related to brain connectivity, such as autism,” noted Just.

The mission of the NIMH is to transform the understanding and treatment of mental illnesses through basic and clinical research, paving the way for prevention, recovery and cure. For more information, visit the www.nimh.nih.gov.
