Teresa Heinz Kerry's Condition Upgraded to Fair
The condition of Teresa Heinz Kerry, the wife of U.S. Secretary
of State John Kerry, has been changed from critical to fair.
Doctors at Massachusetts General Hospital upgraded her condition
after 74-year-old Heinz Kerry underwent further evaluation Monday
morning, according to Glen Johnson, a spokesman for her husband. He
added that Kerry and other family members are with her at the
On Sunday, Heinz Kerry was taken by ambulance to a hospital in
Nantucket, where she and her husband have a home. Later that day,
she was flown to Massachusetts General Hospital.
Heinz Kerry was taken to hospital after she showed symptoms
consistent with a seizure, according to a person in close contact
with the family, the
Toddler With Bioengineered Windpipe Dies
A 2-year-old girl who in April became the youngest person ever
to receive a bioengineered organ died on the weekend.
Hannah Warren was born without a windpipe (trachea) and
underwent the experimental surgery on April 9. The bioengineered
windpipe was made with plastic fibers and cells taken from Hannah's
bone marrow. It was the sixth surgery of its kind worldwide and the
first to be performed in the United States,
The New York Timesreported.
The procedure also involved surgery on Hannah's esophagus, which
never healed properly. She underwent a second operation a month ago
to correct the problem and died from complications of that
procedure, according to Dr. Mark J. Holterman, a pediatric surgeon
at the Children's Hospital of Illinois in Peoria.
"The trachea was never a problem. It was her native tissue that was very fragile," said Dr. Paolo Macchiarini, a specialist in the field of regenerative medicine who implanted the bioengineered windpipe, The Timesreported.
New Gene Sequencing Method Could Boost IVF Success Rate
A new gene sequencing technique to select a viable embryo for
in-vitro fertilization (IVF) has led to the birth of a health baby
boy, researchers announced Monday.
IVF has a high failure rate, with only about 30 percent of
fertilized embryos resulting in pregnancy. Genetic defects are
believed to a major reason. This new method -- called next
generation sequencing (NGS) -- uses updated technology to sequence
the entire genome of an embryo and identify genetic problems,
"Many of the embryos produced during infertility treatments have no chance of becoming a baby because they carry lethal genetic abnormalities," Dagan Wells, of the University of Oxford's NIHR Biomedical Research Centre in the U.K., said in a statement. "Next generation sequencing improves our ability to detect these abnormalities and helps us identify the embryos with the best chances of producing a viable pregnancy."
The research was presented Monday at a meeting in London of the
European Society of Human Reproduction and Embryology,
