UF scientists to play key roles in national children's health study


BY SARAH CAREY
T wo scientists with the University of Florida colleges of Veterinary Medicine and
Public Health and Health Professions will help monitor environmental testing and
exposure assessments for Florida's component in an unprecedented national study
aimed at improving the health of America's children.
UF's component of the the $54 million Florida contract amounts to approximately $10
million, administrators said.
Dr. Nancy Szabo, director of the Analytical Toxicology Core Laboratory and a research
assistant professor with the College of Veterinary Medicine, and Dr. Natalie Freeman, associate
professor and interim director of the College of Public Health and Health Professions' environ-
mental health program, will partner with lead investigator Dr. Mark Hudak, a UF pediatrician
at Shands-Jacksonville, on UF's piece of the project known as the National Children's Study.
One of the largest collaborative efforts in health-related research ever, the NCS will involve
a consortium of federal partners including the National Institutes of Health, the U.S. Depart-
ment of Health and Human Services, the Centers for Disease Control and Prevention and the
U.S. Environmental Protection Agency.
The NCS's goal is to ultimately enroll 100,000 children nationally. To that end, the NIH
has selected 105 counties in the country, including four in Florida, to participate. Each urban
county selected will ultimately assemble a group of 1,000 children and rural counties will
assemble a group of 600 children all of whom will be followed prenatally and through the first
21 years of life.
In Florida, the University of Miami's Miller School of Medicine will be taking the lead role
as the Florida coordinating center. The University of South Florida and the University of
Central Florida are also involved. UF's efforts will primarily focus on 600 children from Baker
County, although Freeman and Szabo will also participate in the Orange and Hillsborough
county sites.
"Having Mark Hudak as principal investigator of the Baker location makes a lot of sense
during the first years of the study, since the primary focus will be on recruiting women before
and during pregnancy and following them through delivery," said Freeman, whose background
is in residential exposure assessment with a particular focus on children. She and Szabo also
are excited about the potential for additional intercollege collaborations that may ensue at UF
from spin-off studies.
Freeman said the NCS is essentially an observational exposure assessment study as well as
a longitudinal epidemiology study. Environmental assessments will include household, air,
water and soil around the household. More specific decisions relating to which contaminants
will be analyzed are expected to be finalized in the next few months. Specific contaminants to
be tested will vary by region.
"We will gather information about lifestyle activities and collect environmental samples for
analysis of a wide range of agents," Freeman said. "Hopefully this data will provide informa-
tion about what children are exposed to and how it impacts their health."
She added that the Florida contract should provide for many jobs in Dade, Hillsborough,
Orange and Baker counties, and ought to be a welcome boon for the entire state in lean
economic times.
"It is largely expected that the folks manning the phone banks, trained for home visits and
the collection of various environmental/biological samples will come largely from the area,"
said Szabo, whose primary role will be to provide quality control and quality assurance for the
Baker County piece of the study.
"This extends beyond the collection or manipulation of data; it involves verification
and evaluation of the personnel involved, biological and environmental protocols, sampling
and site activities and verification/evaluation of corrective actions," Szabo said
Although most of the time-consuming, routine efforts for Baker County such as
phone banks, surveys, site visits for collection of biological and/or environmental samples,
have been subcontracted to a company that has its own quality control system, its activities
will still be monitored and confirmed by UF personnel.
"Since the NCS coordinating center has not yet finalized decisions regarding what
analyses will be conducted or who will provide those analyses on collected environmental and
biological samples, whether or not I play a role in that part of things may not be known for
several years," Szabo added.
Freeman said that besides Szabo's role in monitoring quality assurance and control -

which Freeman called "critical" for a study of this size it was possible that other veterinary
medical faculty who conduct research relevant to both humans and animals might at some
point be involved in other aspects of the NCS.
"One of the focuses of the NCS is trying to understand the development of asthma,"
Freeman said. "In the veterinary college, there already is an established group conducting
asthma-related research."
Along with asthma, however, diabetes, obesity and autism are specifically stated interests
within the NCS. Szabo and Freeman both said all these areas could afford the possibility of
future intracollege collaborations at UF.
"As time goes by and the Florida branch of the NCS gets started, other opportunities of this
nature will surely appear," Szabo said.

Interventional therapy saves dogs with portosystemic liver shunts at UF VMC

BY SARAH CAREY


W hen Delilah, a 6-month-old Labrador Retriever, came to the University of
Florida Veterinary Medical Center in July, she was much smaller than normal
size for her breed and her liver had almost completely stopped functioning.
"From the beginning, we noticed that she was very sick," said Delilah's owner, Robin
Fish of New Port Richey, adding that the AKC-registered chocolate Lab was one of 11
puppies in a litter the Fish family helped raise. "She'd snap back for awhile, but never
played like the other puppies and she was very listless. Soon after their second shots, she
became extremely ill, with severe fevers."
Delilah had a congenital intrahepatic portosystemic liver shunt, a life-threatening
condition through which blood bypasses the liver, leading to organ failure. Because
surgery to treat these types of cases is extremely difficult and often not an option, as was
the case with Delilah, UF veterinarians took a different approach, using minimally invasive
interventional therapy to perform a transvenous coil occlusion of the shunt, enabling the
circulatory blood flow to be redirected through its normal channels.
Today, Delilah is one of two canine patients to have been successfully treated at UF
for this condition through the use of interventional therapy, which employs diagnostic
imaging to guide minimally invasive procedures. Typically the imaging modalities used
for interventional procedures are ultrasound and fluoroscopy, but sometimes they involve
CT and MRI.
In fact, Fish was so excited by Delilah's outcome at UF that she mentioned it to
another couple she met at a social function whose dog suffered from the same condition.
That dog soon became UF's second success story for this particular type of treat-
ment.
"People are excited about these new interventional techniques, but few veterinarians
have the ability to do it just by themselves," said veterinary cardiologist Herb
Maisenbacher, a clinical assistant professor of cardiology at the UF VMC whose primary
interest is in vascular procedures. "I wouldn't attempt this unless surgeons or radiologists
were there to help me. We all bring different skill sets to the table, which makes it pos-
sible."
Various specialized needles, introducers, catheters, guidewires and other devices are
used to access the body in interventional therapies. Although interventional techniques
have been used for years in human medicine, its use in veterinary medicine is in its infancy
in many respects with only one formal training program in existence at the University
of Pennsylvania UF's VMC has implemented a team approach in which several
specialty services are involved in the planning and execution of many interventional
therapies.
"This approach has only improved the care of our patients and our ability to offer
cutting edge treatment," Maisenbacher said. "It's a realm with a lot of promise and very few
limitations. There are many organ system diseases that can be treated by these procedures."
UF cardiologists were trained in the highly technical procedure to treat intrahepatic
portosystemic liver shunts three years ago by interventional veterinary specialist Chick
Weiss from the University of Pennsylvania. Delilah's case gave the UF team its first
opportunity to make use of these new skills. The procedure involves placing a wide bore
catheter in the jugular vein; using fluoroscopy, or real-time X-rays, to locate the vascular
shunt; placing a metal stent in the vena cava and finally deploying coils to create the
occlusion.

screens that the team are watching show the fluoroscopic images of the catheter in the body, allowing them to move it
into position within the desired vessel. (Photo by Sarah Carey)

Advantages of interventional therapies generally include shorter hospital stays and
reduced mortality rates but most importantly, these techniques offer alternative treatments of
conditions for which no standard treatments may exist, or for which the standard treatment -
usually surgery offers unacceptable risk to the patient. Disadvantages include the
procedure's cost, which can be in the thousands of dollars.
"The metal stent alone costs $1,500," Maisenbacher said. "The good thing is, we can take
a dog that is very sick and turn it into a healthy dog."
Veterinary radiologist Shannon Holmes said that currently interventional radiology is used
at UF to treat intrahepatic portosystemic vascular anomlies, patent ductus arteriosus, tracheal
collapse, urethral obstructions and to deliver regional chemotherapy via arteries supplying a
tumor.
"It truly is a team approach, as many specialists are often involved in the procedure,"
Holmes said. "It requires an excellent knowledge of three-dimensional radiologic anatomy and
is an exciting field of radiologic practice that is rapidly expanding, especially in veterinary
medicine."
As for Delilah, Fish said she is "doing beautifully."
"I told the doctors at UF, I didn't know what to do for them or how to thank them, so I just
sent them another liver shunt dog so they could save another life," Fish said. "I was blessed
enough to be able to give them another dog to help."


"Two Lab owners meet at a party..."

Shared story leads to second successful liver shunt treatment at UF


BY SARAH CAREY

T he grapevine is alive and well, as the Tampa-area owners of two young
chocolate Labrador Retrievers can attest. The dogs both are doing well after
recently receiving unique interventional therapy at UF's Veterinary Medical
Center to correct life-threatening liver shunts.
Robin Fish and Shiloh Schrantz met at a mutual friend's birthday party in July and
began chatting. Turns out, both women owned puppies who both happened to be
extremely ill from the same medical condition.
"We were at a jazz and blues club where there was live music and it was hard to hear
because of all the noise," Schrantz said. "All of a sudden my husband said, 'Listen to these
people; their puppy has issues like ours."'
"So I went over and said, 'I don't mean to be snooping, but it sounds like your dog
might have exactly the same problem that ours has," Schrantz said.
At this point, Schrantz's dog, Bear, had survived risky surgery in January but his
veterinarians failed to locate the shunt. Schrantz said her vet pushed the couple to obtain
additional tests but they were reluctant to pursue other options, partly out of worry that
any new procedure would be hard on Bear.
"It was being managed through medication and prescription dog food, but we did
stall," Schrantz said. "He wasn't thriving."
Fish, on the other hand, shared with her new friend that Delilah was awaiting a
procedure at UF known as interventional therapy.
"Their dog was dying and here I was, with my dog about to get this procedure," Fish
said. "It was a very atypical thing."
The Fishes had known almost immediately after Delilah, who was one of 11 AKC-
registered puppies born to a litter they helped raise, was very sick.
"I saw she was not playing as much as the other pups," Fish said. "She was picky with
her food and very listless. Then she began having severe fevers."

When her local veterinarian told them about UF, they immediately scheduled an
appointment. UF veterinarians verified through additional tests that Delilah had an
intrahepatic portosystemic liver shunt in a hard-to-find spot within the central lobe
of the organ, but could not receive surgery until her condition improved.
"They said, 'we have to get her in a surgical state,'" Fish recalled. "So they put

her on medication and on a no-protein diet, and we had to wait a month."
It was in that window of waiting for surgery that Fish and Schrantz had their
conversation at the party.
"We were so surprised to hear all the good things they said, so we called the
university and one thing led to another," Schrantz said.
The highly technical and sophisticated procedure UF performed on both Delilah
and Bear is known as interventional therapy and involves close collaborations
between veterinary radiologists and cardiologists to locate the problematic shunt,
place a stent and implant coils within the specific vessel to reroute blood flow properly
through the circulatory system.
Although UF's team had been trained in the procedure, Delilah was the first patient
to receive it at the VMC.
Bear now weighs 83 pounds and is "doing great" despite being a few months
behind his companion dog developmentally.
"We could do with not going through the puppy thing twice, but we just sacrificed
another pillow to the great god of puppies," Schrantz said.
Delilah now weighs 61 pounds a 30 pound increase since her UF procedure.
"We call her, 'Happy Girl,"' said Fish. "She is our little princess and she is so
spoiled."


Legato, former director of development and

alumni affairs, now moves into senior position

with the UF CVM




K arenLegato has been named senior
director of development and alumni
affairs at the University of Florida College
of Veterinary Medicine.
Legato has 25 years of fundraising
experience in higher education, nine of
which have been at UF's veterinary
college. She has worked with donor
events, corporate solicitations and campus
campaigns.
A member of the UF veterinary
college's development staff since 1999,
Legato most recently has served as
director of development and alumni affairs
for the college. In her new position, she
replaces Zoe Seale, who has taken ajob as
senior director of development and alumni
affairs at UF's College of Liberal Arts and
Sciences.
Legato's promotion was effective
Oct. 17.
She holds a bachelor's degree in Karen Legato
communication from Slippery Rock
University, Slippery Rock, Pa. She worked
from 1984-1999 at Slippery Rock as both an executive assistant and a special events coordina-
tor in the university's advancement office.
Prior to that, she worked for seven years as a farm manager and equine trainer at Arcadian
Arabians in Slippery Rock, and for nine years as the executive secretary to the president of
General Nutrition Corporation in Pittsburgh.
In her most recent position at the veterinary college, in addition to fundraising for the
college, Legato was responsible for cultivating relationships among several constituencies,
including alumni, donors, grateful clients of UF's veterinary hospitals and others from various
animal-oriented clubs and industry groups.
Most people think of development as 'just fundraising" but there is more to it than that,
Legato said.
"My goal is to educate people who already have an interest in the college's mission of
teaching, research and patient care about ways in which their contributions can meaningfully
advance that mission," Legato said. "We aren't just asking people for money; we are establish-
ing and nurturing relationships and providing opportunities for people to give financially to a
cause they already believe in."
In the nine years Legato has been at UF, the college has consistently been ranked in the
top 10 of the 28 fundraising units across campus, both in terms of money raised and percentage
of goal achieved.


Good hick. Zoe!

Clinical pathologists at UF, CVM former

veterinary resident play key role in diagnosing

foreign equine disease


BY SARAH CAREY


A rare and contagious tick-borne
disease affecting horses was
diagnosed in August by an
Ocala equine veterinarian, confirmed by
University of Florida faculty members, and .
contained, thanks to state agricultural
officials.
The reportable foreign disease known as
equine piroplasmosis (EP) is transmitted by a
tick endemic to many tropical and subtropical
regions. EP was believed to be eradicated
from the U.S. inthe 1980s.
UF's involvement began when former UF equine medicine resident Dr. Carol Clark, now in
private practice with Peterson & Smith in Ocala, recognized clinical signs and laboratory
results suggestive of the disease in a horse being treated at her facility. Clark contacted the
College of Veterinary Medicine in hopes that a clinical pathologist could confirm the diagno-
sis.
"She saw what she thought were protozoal organisms in red blood cells, and sent a blood
sample for us to evaluate'" said Dr. John Harvey, the college's executive associate dean and a
board-certified clinical pathologist.
"I wasn't on duty at the time, but examined a stained blood film after being called by our
technologists'" Harvey said. "I confirmed that the organisms present most closely resembled
Babesia equi, which has recently been reclassified as Theileria equi." This organism is one of
two known causes of piroplasmosis in horses. The other is a larger protozoa named Babesia
caballi.
Once Harvey confirmed the diagnosis, Clark contacted the state veterinarian's office in
Tallahassee to report the finding and arrangements were made to perform a necropsy on the
horse at UF.
Dr. Steeve Giguere, professor of equine medicine, examined the horse before it was
euthanized. The horse was depressed and had fluid accumulation in his ventral abdomen and
legs. His mucus membranes appeared slightly yellow and small hemorrhages were present. His
urine appeared reddish brown. These clinical signs, along with anemia documented during
blood evaluation, were consistent with EP.
Dr. David Allred, an associate professor in the college's department of infectious diseases
and pathology, was contacted to see if he could assist in further characterizing the disease
through DNA sequencing.
"We wanted to verify that there wasn't some other previously unrecognized pathogen
infecting this horse'" Harvey said.
Allred said the gene sequencing project has not been completed yet, but that "evidence so
far points to T equi."
"T equi is not cycling in wildlife reservoirs in Florida'" Allred said. "Some piroplasmosis
species are able to jump between hosts under the right conditions, which is another good
reason for understanding exactly what species we're dealing with."
While UF's veterinarians focused the identifying the specific organism involved, Florida
agricultural officials began an extensive epidemiological investigation to determine if other
horses were infected and to find out how this horse became infected.
A total of 19 horses tested positive on seven premises and all positive animals have been
euthanized to prevent spread of the disease. No foreign ticks or ticks carrying the EP causing
organism have been found, officials said.
Current evidence suggests that two infected Mexican horses were brought to Florida and
EP was spread among those horses using contaminated needles and blood. Officials speculate
that this may have involved blood doping of horses in an attempt to improve racing perfor-
mance as part of an illegal gambling enterprise.
