Natural births better for babies

May 30, 2010

Bacteria ... A scientist says babies benefit from being born
BABIES born by caesarean section are more vulnerable to asthma,
allergies and infection as they miss out on receiving their mothers'
good bacteria during birth, a scientist says.

Professor Patricia Conway, of the School of Biotechnology and
Biomolecular Sciences at the University of NSW, said babies delivered
vaginally received protective bacteria as they passed through the
birth canal. Left on the baby's skin, this bacteria could then
colonise the intestine and help inoculate newborns against hospital
bugs. Gut flora was also crucial for developing a balanced immune
system, Professor Conway said. "With a C-section, the newborn baby
misses an opportunity to pick up a lot of mum's good bacteria," she

"This can have long-term health implications, as the development of a
good intestinal ecosystem is necessary for health and immunity to
allergies, from childhood right through to adulthood."

Professor Conway said emergency caesareans, performed after labour had
begun, meant babies did receive some of the beneficial bacteria,
particularly if the waters had broken. But elective caesareans were
''sterile'' and gave babies no chance to pick up any of the mother's
good bacteria.

However babies had other chances to receive their mother's bacteria,
during skin-to-skin contact directly after birth and if they were

Australian College of Midwives vice-president Hannah Dahlen said
babies born vaginally had the advantage of hormonal surges during
labour, which made them more wide-eyed and able to connect with their

Both mother and baby experienced a surge in catecholamines - the fight-
or-flight hormone - during labour, making babies more alert at birth.

Recent studies had shown white blood cells in babies born by caesarean
were different to those born vaginally, potentially altering the way
their bodies responded to attacks on their immune systems for the rest
of their lives.

The studies could explain dramatic increases in rates of diabetes,
testicular cancer, leukaemia and asthma among babies born surgically,
Dr Dahlen said.

So let a child die if it cannot be born naturally.

Great call, look at all the money saved!

Yes, Ralph Pauley Autrey Jr. champion of infants!

Not, my little fruitcake.

UM School of Medicine study finds vaginal microbes vary among healthy

Differences seem divided between ethnic groups; Scientists hope
research leads to personalized medicine
The delicate balance of microbes in the vagina can vary greatly
between healthy women, according to a new study led by the University
of Maryland School of Medicine's Institute for Genome Sciences.
Researchers hope further study will lead to personalized reproductive
medicine for women, allowing doctors to tailor each woman's treatment
and health maintenance strategies to her individual microbial make-up.

The study, published online the week of May 31, 2010, in the journal
Proceedings of the National Academy of Sciences, used genomics-based
technologies to examine the vaginal microbes in 400 women. The work, a
collaboration between the Institute for Genome Sciences and
researchers at the University of Idaho, is the first in-depth, large-
scale molecular characterization of vaginal microbial communities. The
research is an example of an emerging field of genomics, the study of
the human microbiome. The human microbiome refers to all of the
microbes that live on and in the human body. Scientists believe these
tiny organisms interact closely with the human genome and play a
critical role in human health and disease. In the vagina, these
communities of microbes play a critical role in maintaining and
promoting a woman's health and in protecting her against disease.
Vaginal microbes provide protection mainly by producing lactic acid to
create an acidic environment that is hostile to certain harmful
microbes or infection.

"The surprising finding here is that some women can be healthy while
still harboring different communities of microbes," said Jacques
Ravel, Ph.D., associate professor of microbiology and immunology at
the University of Maryland School of Medicine and associate director
of the Institute for Genome Sciences. "Even microbes that were
previously believed to be detrimental to a woman's health seem to be
part of a normal ecosystem in some women, according to this study.
Further research is needed to establish the function of these microbes
and the communities in which they appear. Some of the seemingly
beneficial microbial communities seem to be associated with a higher
pH — a measure of acidity — which is usually considered to be

"We've found we can actually group women by the type of microbes they
have in the vagina," says Dr. Ravel. "We hope this is leading to
personalized medicine. The study shows that doctors should not assume
every woman is the same. We may not need to personalize reproductive
medicine down to the individual woman, but by which microbial group
they belong to. The information about each woman's vaginal microbial
community could inform how doctors treat her for vaginal conditions.
It could help drive the development of better treatments to
reestablish vaginal health. Understanding these microbial communities
could also help us determine which women might be at higher risk for

Yeast infections or bacterial vaginosis, a bacterial infection of the
vagina, cause discomfort in patients and can have serious health
effects. About 25 to 30 percent of women have bacterial vaginosis on
any given day, and it is the most common vaginal infection that causes
women of reproductive age to visit their primary care physician. The
infection has been associated with an increased risk of such problems
as acquiring sexually transmitted infections and even pre-term
delivery during pregnancy. "If we could identify women as being at a
high risk for developing bacterial vaginosis, we could develop
preventive methods to lower the risk of infection," says Dr. Ravel.

The study involved vaginal samples taken from 400 women representing
four ethnic groups equally: black, Hispanic, Asian and white. Ligia
Peralta, M.D., associate professor of pediatrics and microbiology and
immunology at the University of Maryland School of Medicine,
collaborated with clinicians at Emory University to collect the tissue
samples. Dr. Ravel and his group at the Institute for Genome Sciences
worked with co-investigator Larry Forney, Ph.D., a professor at the
University of Idaho, to use advanced genomics and bioinformatics
technology to gather information on the microbes in the samples and
analyze the data.

The researchers found five main groups of microbial communities, and
that the proportion of women in each community varied by ethnicity.
They also found that microbial communities that may not offer women
optimal protection were more common among Hispanic and black women
than they were in Asian and white women.

"The data highlight potential ethnic disparities and a need for more
personalized medicine," says Dr. Ravel. He adds that he does not
expect gynecologists will immediately overhaul their standard
practices, but the study is an important starting point for future
studies. Dr. Ravel and Dr. Forney are continuing to study the vaginal
microbiome, including examining vaginal samples collected daily from
women over a period of time to chart how each woman's microbial
community changes from day-to-day and how that may affect the woman's
health. The goal of that study is to develop a better understanding of
the molecular and genetic mechanisms behind these differences.

"Groundbreaking basic science discoveries like this are paving the way
for personalized medicine, a new field we hope will allow us to tailor
preventive techniques and therapeutics to each patient's needs," says
E. Albert Reece, M.D., Ph.D., M.B.A., acting president of the
University of Maryland, Baltimore and John Z. and Akiko K. Bowers
Distinguished Professor and dean, University of Maryland School of
Medicine. "I am confident that our top-tier scientists at the
Institute for Genome Sciences will continue to play a critical role in
advancing this new field of medicine in order to improve human
