Spray Tan Chemical Could Pose Health Risk:
Experts
The active chemical in spray tans has the potential to cause genetic
alterations and DNA damage, according to a panel of medical experts who
reviewed 10 of the most current publicly available scientific studies on
dihydroxyacetone (DHA).
The panel, which included six experts ranging across the fields of
toxicology, dermatology and pulmonary medicine, reviewed the evidence at
the request of ABC News.
After reviewing the studies, the panel member said they “have concerns”
about DHA. It is the main chemical component in spray-on tans, which are
touted as a safe alternative to tanning beds.
None of the studies involved humans, but some found that DHA altered
genes in numerous types of cells when tested in labs, ABC News
reported.
“These compounds in some cells could actually promote the development
of cancers or malignancies, and if that’s the case then we need to be wary
of them,” said panel member Dr. Rey Panettieri, a toxicologist and lung
specialist at the University of Pennsylvania’s Perelman School of
Medicine.

NYC Health Board Supports Ban on Large, Sugary
Drinks
A proposal by New York Mayor Michael Bloomberg to ban the sale of
large, sugary beverages at local restaurants has strong support from the
city’s board of health.
In a unanimous vote Tuesday, the board decided to begin a public
comment period on the proposal and several members spoke strongly in favor
of the move to limit sizes of sugary drinks to 16 ounces, the
Associated Press reported.
A public hearing is scheduled for June 24 and a formal vote on whether
to approve the measure will come later.
The proposal is opposed by the New York City Restaurant Association,
which considers it an infringement on consumers’ legal rights, the
AP reported.

Scientists Harvest Stem Cells Long After
Death
It’s possible to harvest certain stem cells from people more than two
weeks after they’ve died and then revive the cells to divide into new,
functioning cells, according to a new study.
“Remarkably, skeletal muscle stem cells can survive for 17 days in
humans and 16 days in mice, post mortem well beyond the 1-2 days currently
thought,” the French scientists said in a statement, Agence
France-Presse reported.
These stem cells also retained their ability to develop into perfectly
functioning muscle cells, says the study in the journal Nature
Communications.
The researchers also found that stem cells taken from bone marrow
remained viable for four days after lab mice died, AFP
reported.
While further research is required, the findings suggest that dead
people could provide a new source of certain types of stem cells that can
be used to treat a number of diseases.

NYC Wants Parental Consent Form for
Circumcision Ritual
Orthodox Jewish parents should be required to sign a consent waiver
before male babies undergoes a circumcision ritual that may expose them to
dangerous infections, New York City health officials proposed Tuesday.
During the ritual, an adult male uses his mouth to suck away blood from
the wound created by the removal of the infant’s foreskin, according to
The New York Times.
A report released last week by the federal Centers for Disease Control
and Prevention said that between 2000 and 2001, 11 newborn babies in New
York contracted the herpes simplex virus after the ritual.
Ten of the babies were hospitalized, two suffered brain damage, and two
died, The Times reported.
In response to the CDC findings, the NYC health department issued a
statement strongly urging that direct oral-genital suction not be
performed during the circumcision ceremony, and also announced that a
number of hospitals agreed to distribute a pamphlet warning parents about
the risk of at-home circumcision.
City health officials said Tuesday that the next step is to get the
Board of Health to require all parents who want direct oral suction to be
used at a circumcision ceremony to sign a consent form indicating that
they are aware of the risk of infection, The Times reported.

WHO Expert Panel Cites Diesel Exhaust as
Carcinogen
Diesel exhaust causes cancer, the International Agency for Research on
Cancer (IARC) said in a ruling released Tuesday after a weeklong
discussion.
The agency, a part of the World Health Organization, said its decision
means that diesel exhaust could be ranked as important a public health
threat as secondhand smoke, CBS News and the Associated
Press reported.
The risk of developing cancer from diesel fumes is small but so many
people breathe in the fumes that boosting the status of diesel exhaust
from probable carcinogen to carcinogen was an important change, said the
agency.
“It’s on the same order of magnitude as passive smoking,” said IARC
Director Kurt Straif, CBS/AP reported. “This could be another big
push for countries to clean up exhaust from diesel engines.”
