A new study at UC San Francisco shows bike accidents on the rise, with the most crashes hitting people over 45.
They looked a info from 1998 to 2013. Hospital admissions for bike mishaps more than doubled--especially head and torso injuries. (Sept JAMA)
The injuries were bad too--not just enough for the ER, but also for hospital admission.
One doctor said if a 25-yr-old and a 60-year-old get an injury, it's likely the 60-year-old's will be worse.
Head injuries went from 10% of the total to 16%.
Why? More speed racing, faster bikes, and maybe meaner cab drivers?
So take a spinning class--no cab drivers would ever go there..

This advice comes from Michael J Misialek, MD, assoc chair, dept of pathology, and assistant clinical prof in pathology at Tufts. He is the guy who looks at PSA screenings and biopsies.
PSA stands for Prostate Specific Antigen. It's a blood test using the same blood they take for cholesterol screening. PSA testing, however, is not always ordered.
--There is no consensus wbout when to start PSA screening or how often to do it. The controversy is that is can lead to costly treatment for cancer that may not be aggressive. Misialek recommends at least talking with your doctor about it at age 40.
--Elevated PSA does not always mean you have cancer. It can be a good indicator, but other things cause elevated PSA, too. Eighty percent of cancers have an elevated PSA.
--A biopsy confirms the diagnosis. This will show the type of cancer if it is cancer.
--Request your pathology report. Talk to the pathologist.
--Be part of your care plan. You will make your own decisions.
--Rushing to surgery and intense treatment is not always best. Sometimes it's best to begin a period of active surveillance to monitor the cancer's growth. If surgery is necessary at some point, it can be followed by radiation, chemo or hormonal therapy.
There are some new tests coming, also. The Prostate Health Index--now in early trials--may be more accurate than the PSA.
Genetic testing may also predict risk. The same gene that is thought to cause some breast and ovarian cancers--BRCA1 and BRCA2--may also be linked to early-onset prostate cancer.
These are areas to explore with your doctor. Don't be afraid to ask questions, do some research, and don't just freak out and insist on surgery to get the thing out...
Think before you react.

Blockages that reduce blood flow a small amount can be treated with cholesterol-lowering drugs of aspirin. More severe blockages require a stent or bypass surgery.
The measure of blood flow is call fractional flow reserve (FFR). Before now, checking this required a big-deal procedure in which a thin tube was inserted in the groin artery, pushed all the way to the heart, a thin wire then put in the blockage and a sensor measured the FFR.
But now, a test has been developed by HeartFlow Inc and approved by the FDA, which basically uses CT scan technology to measure FFR from outside the body.
The CT scans create a 3D model of the arteries and computer programs simulate blood flow to those arteries to see how blocked they are.
"This is a game changer," says cardiologist Mark Rabbat, MD, of Loyola. the Loyola University Medical Center is the first to offer this.
Will other hospitals be far behind?

But it is not nutty--a professor of botany at the Univ of Grenada, Spain, is studying how trees in green spaces contribute to or cause allergies. (J of Environmental Science, special section)
She and all her siblings suffer from allergies. They are immersed in this subject. The city of Grenada is her lab. It has one of the highest pollen counts in the world.
They classified all the trees in Grenada's parks and green spaces. They recorded the type of pollination, the length of the pollination period, and the potential of each tree for causing allergies.
Surprise--many of the most common trees were the worst offenders.
They also learned that allergies were never considered in designing these spaces. In the future, she says, urban green spaces can be "comfort islands." Not only would they not cause or make allergies worse, the could even clean pollutants out of the air.
So maybe it sounds nutty to try to make the out-of-doors allergy-free, but this woman said, hey, why not?

Congress is about to vote on reauthorizing the healthier lunch regulations--and a new study in Public Health Reports (online), Aug 25, found students were putting more healthy stuff on their trays but consuming less of it, increasing waste by 35%.
The researchers at the Univ of Vermont looked in the trash bins--kids were taking whole apples and then tossing them. They took digital pix of trays as they left the cashier, then estimated what was tossed.
When kids selected, they preferred processed fruits and veggies, such as the tomato paste on pizza. Or 100% fruit juice.
Some ideas to prevent this?
--Cut up veggies and serve them with dip or mixed into the meal.
--Slice fruits rather than serving them whole.
--Get kids involved with gardening or Farm-to-School programs.
--Public health programs that push fruit and veggies at home.
The biggest hope is kindergarteners who enter school under the guidelines...They will know no other way.
But will even that kid peel an orange?
