Male-female ring finger proportions tied to sex hormones in embryo; may offer health insights
 
01:45
Biologists at the University of Florida have found a reason why men's ring fingers are generally longer than their index fingers — and why the reverse usually holds true for women. The finding could help medical professionals understand the origin of behavior and disease, which may be useful for customizing treatments or assessing risks in context with specific medical conditions. Writing this week in the Proceedings of the National Academy of Sciences, developmental biologists Martin Cohn, Ph.D., and Zhengui Zheng, Ph.D., of the Howard Hughes Medical Institute and the department of molecular genetics and microbiology at the UF College of Medicine, show that male and female digit proportions are determined by the balance of sex hormones during early embryonic development. Differences in how these hormones activate receptors in males and females affect the growth of specific digits.

Parker Stevens doesn't think twice about doing things for others, so shaving his head to raise funds for children with cancer was a sacrifice he was well equipped to handle. Last year, Parker's father, Jeff Stevens, a web content optimizer at UF&Shands, the University of Florida Academic Health Center, participated at an event sponsored by UF's division of pediatric hematology and oncology. He and other volunteers shaved their heads to encourage friends and family to help raise funds for children in the hospital. After learning that such an event was not scheduled this year, Parker, 10, decided to take matters into his own hands.

UF study strengthens concerns about long-term use of certain painkillers
 
01:56
Painkillers such as ibuprofen, naxopren and celecoxib provide needed relief for many patients who have chronic pain. But an ongoing source of contention is whether those drugs and others in their class known as nonsteroidal anti-inflammatory drugs, or NSAIDs, are linked to harmful health effects. Now a new study from the University of Florida raises the concern about potential risks to a higher degree than before, finding a doubling of deaths from heart attack, stroke and related events among people who have both hypertension and coronary artery disease and use the drugs long term. The findings, based on data from the international INVEST clinical study of hypertension therapies, are published in the current issue of The American Journal of Medicine. "It does strengthen our practice recommendations," said lead author Anthony A. Bavry, M.D., M.P.H., an assistant professor of cardiovascular medicine in the UF College of Medicine's department of medicine. Physicians already discourage the use of NSAIDs among the elderly and after heart attacks, on the basis of several studies showing that the drugs are linked with a higher risk of stroke and heart attack. But the UF researchers, including senior author Carl J. Pepine, M.D., a professor of cardiovascular medicine in the UF College of Medicine, advise patients to talk to their doctors before stopping use of prescribed treatments. "It's a tricky issue, because NSAIDs are useful for relieving pain, and that is much of what we do in medicine — alleviate pain and suffering," said Deepak L. Bhatt, M.D., M.P.H., an associate professor of medicine at Harvard Medical School and chief of cardiology at the VA Boston Healthcare System, who recently published findings that NSAIDs are linked to a higher risk of stroke. "Unfortunately, most medications have some potential side effects, and it's important to know what those might be." Bhatt was not involved in the UF study. Patients who have both high blood pressure and coronary artery disease are generally put on aspirin, a unique type of NSAID, to reduce their risk of a heart attack. Physicians are concerned that giving those patients other NSAIDs for pain relief could cancel out aspirin's beneficial effects and raise the risk of negative cardiovascular effects. The UF research team took advantage of the availability of INVEST study data from 882 chronic NSAID users and almost 22,000 intermittent or nonusers to try to settle the question. They looked at patients who reported using NSAIDs over an average of about three years, to see whether there was an increase in adverse events or cardiovascular-related death compared with patients who did not use those pain medicines long term. The risk of death from cardiovascular causes was 2.3 times higher among patients who chronically used the drugs than among other patients. NSAIDs are thought to act in a variety of ways to increase cardiovascular risk. They are thought to prevent aspirin's protective anti-clotting effect by preventing the aspirin from binding properly to platelets in the blood. Some NSAIDs might also increase bleeding risk. In addition, NSAIDs raise blood pressure, thus potentially raising the risk of heart attack and stroke. Some NSAIDs have already been removed from the market because of concerns about an elevated risk of heart attack and stroke.

College students often miss mark when reporting 'normal' hearing
 
01:40
GAINESVILLE, Fla. --- Some college students who think they have normal hearing may actually be overestimating their abilities. In a University of Florida study of college students who believed they had normal hearing, one-quarter did not have normal hearing sensitivity. It was an unexpected discovery made during the early stages of another study. UF researchers at the College of Public Health and Health Professions were recruiting college students with normal hearing for a study on temporary hearing loss and personal music players. "You would expect normal hearing in that population," said lead researcher Colleen Le Prell, an associate professor in the department of speech, language and hearing sciences. "The criteria for normal hearing we used for the study were, we thought, extremely liberal criteria." The study findings appeared last month in a special supplement of the International Journal of Audiology. The UF study involved 56 college students with an average age of 21. Prospective participants who reported normal hearing in initial phone interviews were asked to visit the lab for hearing tests to determine their study eligibility. The participants completed a health survey and a questionnaire about their previous exposure to loud noise, such as playing a musical instrument, listening to personal music players, using lawn equipment or attending sporting events or concerts. Participants then received hearing tests in a sound booth at all of the sound frequencies used in a traditional full clinical hearing test. In 25 percent of the participants, researchers measured 15 decibels or more of hearing loss at one or more test frequencies, an amount that is not severe enough to require a hearing aid, but could disrupt learning, Le Prell said. Of the participants who demonstrated hearing loss, 7 percent had 25 decibels or more of hearing loss, which is clinically diagnosed as mild hearing loss. Hearing loss occurred in both the range of frequencies identified as "speech frequencies" because of their importance for speech discrimination, as well as the higher frequencies of 6 and 8 kilohertz. "With high frequency hearing loss a person can miss a lot of subtle speech sounds, making it much harder to discriminate different vowels or phonemes," Le Prell said. "It would also be much harder to hear sounds like bird songs or children's voices." Several experts have speculated that increased rates of hearing loss in young adults may be related to the popularity of personal music players. The UF study did find that the highest levels of high frequency hearing loss were in male students who reported using personal music players. More research is needed with a larger sample size to determine the role of personal music players and gender in noise-induced hearing loss, Le Prell said. "Dr. Le Prell's article is extremely interesting and her findings are consistent with what we know of early noise-induced hearing loss: It's insidious and more prevalent in young men than women," said Brian J. Fligor, director of diagnostic audiology at Children's Hospital Boston and an instructor in otology and laryngology at Harvard Medical School, who was not involved in the study. "Their sample size was fairly small, making it hard for the researchers to actually find something, but the fact they did shows the size of the effect is of both scientific and clinical significance. These small but measurable changes in hearing in this young adult population suggest that they will have communicatively important hearing deficits earlier, perhaps decades earlier, than they should, due to the premature wear and tear on their hearing system."

Potential new drug treats blood disorders by halting overproduction of blood cells
 
01:22
Like a switch stuck in the on position, the bone marrow can churn out blood cells that bloat internal organs and clog blood vessels, leading to life-threatening disease. Now University of Florida scientists have discovered a potential new drug that can throw the switch on the runaway blood cell-production mechanism. The drug shrinks cell-gorged organs and stems the overproduction of blood cells, and the researchers are working toward bringing it into clinical trial in one year. "The disease has a path it's going to take and you need to be able to alter that path — our drug does that to a reasonable extent," said Peter P. Sayeski, Ph.D., an associate professor of physiology and functional genomics in the UF College of Medicine, who led the research team. The work, funded in part by the National Institutes of Health and the American Heart Association, is described in the current issue of the Journal of Biological Chemistry. The new drug, dubbed "G6" by the researchers, targets a group of life-threatening and hard-to-diagnose diseases called myeloproliferative neoplasms, or MPNs, that occur when the bone marrow cranks out too many red cells, white cells or platelets because of a mutant form of a protein called Jak2 that is key to blood cell formation. The condition is estimated to affect about 170,000 people in the United States, according to data from the MPN Research Foundation, also known as the MPD Foundation. "These bone marrow cells are replicating and growing out of control because one very important protein is stuck in the on position," said Christopher R. Cogle, M.D., an associate professor of hematology/oncology in the UF College of Medicine and a member of the UF Shands Cancer Center. The result is blood counts so high they elevate patients' risk of stroke, bleeding, infection and blood clots in various parts of the body. Ironically, the condition can also lead to low blood cell count and anemia symptoms, because it impedes the flow of normal cells from the bone marrow into the blood stream.

A school's scholastic success can keep kids from drugs, alcohol
 
01:36
GAINESVILLE, Fla. — In building a culture where even the most underprivileged students can achieve academic success, schools may be able to inadvertently stymie another problem: drug and alcohol use. While studying 61 inner-city middle schools in Chicago, University of Florida researchers found that students in schools that performed better than expected were less likely to use drugs and alcohol, steal or participate in fights than children in schools that did not perform as well. The study was published in March in the journal Prevention Science. Higher performance in the classroom reduced the rate of drug use and delinquency in schools by as much as 25 percent, said Amy Tobler, Ph.D., M.P.H., a research assistant professor of health outcomes and policy in the UF College of Medicine and the study's lead author. The schools in question all had high populations of ethnic minorities and children from underprivileged homes, factors often linked to lower achievement in schools, Tobler said. "It could be good teaching, better administration, whatever these schools are doing, if we can replicate it, it will lead to not only academic achievement but improvement in healthy behaviors as well," Tobler said. "Some schools can break that strong link between sociodemographic disadvantage and drug use and delinquency." The researchers collected data in the schools between 2002 and 2005, following students in their sixth-, seventh- and eighth-grade years. Academic achievement scores were based on standardized tests on reading and math, which public school students in all states are required to take. The researchers determined how well schools should perform based on each school's own sociodemographic factors and compared that to how well they actually fared. They then compared that information to achievement and attendance records and data collected about students' drug and alcohol use. Of the 61 schools, seven performed better than expected academically, a link that seemed to help keep kids in class and off drugs and alcohol, Tobler said. "I think the study is provocative, and it has one remarkable aspect: Schools that do better have effects that are not (solely) academic, and that tells you that the whole culture of the school is important," said David Berliner, Ph.D., a Regents professor emeritus of education at Arizona State University, who was not involved with the study. "It is a school-culture effect. It is not surprising, in a way. If you can get low-income kids to identify with a school, you get better kids at the end." The researchers refer to this link between a school's academic culture and students' healthy behaviors as "value-added education," a concept that was first shown in the United Kingdom in a different population of students. The UF study shows that this can work among students facing disadvantages as well, Tobler said. "I was really curious when we started this if we would have any schools that were overcoming that link between sociodemographics and high-risk behaviors," Tobler said. "That we had seven schools that were doing it is pretty encouraging, I think." But the progress could be undercut by proposed funding cuts to educational programs across the country, Tobler added. "Almost all states are cutting budgets to public education," Tobler said. "We are increasingly asking them to do more and more with fewer resources. The extent to which schools can achieve this value-added education or continue it may be severely limited by budget cuts." Other researchers who contributed to the study include Kelli Komro, Ph.D., and Alexis Dabroski of UF; Paul Aveyard, Ph.D., of the University of Birmingham; and Wolfgang A. Markham, Ph.D., of the University of Warwick.

Active older adults less likely to become cognitively impaired, UF researchers find
 
01:38
Reaching over to make the bed or bending to get a grocery bag might not be the typical idea of being physically active. But all those everyday movements add up and could contribute to health benefits, especially among older adults -- even if it's not clear just how much energy seniors are exerting. Previous research has been mostly based on error-prone self-reports of physical activity rather than actual measurements. Now, University of Florida researchers and colleagues have used laboratory-based methods to objectively measure the amount of energy older adults use up as they go about their daily activities, and linked that to cognitive performance. The researchers found that older adults who expend relatively high amounts of energy in their daily activities are substantially less likely to become cognitively impaired than those who exert less energy. The findings are published in the July 25 issue of the Archives of Internal Medicine. "There are millions and millions of people who don't exercise, but we're beginning to understand that a lot of these people do a lot during the day, and they are likely to accumulate more energy expenditure during the day than others who go out and exercise," said study co-author Todd Manini, Ph.D., an assistant professor in the department of aging and geriatric research at the University of Florida College of Medicine and the UF Institute on Aging. "These studies are starting to shed light on the fact that accumulating activity during the day can potentially provide health benefits." A growing body of research points to the promise of physical activity as a way to prevent or even treat cognitive impairment. But to figure out what types of activities are necessary, and how much, researchers need better estimates of energy spent in various activities.

New Pediatric ER at Shands will enhance emergency care for children
 
01:33
Children are not small adults. This is never more evident than when an accident or urgent medical problem arises and parents need fast access to specialized care designed to meet their child's needs. On July 1, the new Pediatric Emergency Room at Shands Hospital for Children at the University of Florida will open, becoming north central Florida's first emergency room specifically geared toward kids. Located at Shands at the University of Florida, the Pediatric ER will have a separate entrance with free valet parking for adults transporting children, and an adjacent parking garage for visitors. Calming, child-friendly décor with a nautical theme enhances the check-in and waiting areas, with porthole windows, saltwater aquariums and floors made to look like waves adding to the atmosphere. More important, families will have access to an expanded team of UF pediatric emergency medicine physicians and Shands pediatric emergency-trained nurses, additional treatment space and the latest medical technology. "This new Pediatric ER benefits our patients and our UF&Shands teams," said Jennifer Light, M.D., UF College of Medicine clinical assistant professor of emergency medicine and Pediatric ER medical director. "We've created an environment just for families, staffed by people committed to the care of children. This generates great positive energy and the opportunity for us to improve services and the whole experience for young patients and their families." The Pediatric ER will be staffed by seven UF board-certified or board-eligible pediatric emergency medicine physicians and 22 Shands pediatric-trained emergency medicine registered nurses. The team will be able to treat up to 24,000 pediatric emergency patients a year.

Genetic analysis of costly cattle disease may aid in vaccine development
 
01:47
Researchers at the University of Florida College of Veterinary Medicine say proteins common to multiple strains of Anaplasma marginale, a tick-borne pathogen that costs the U.S. cattle industry millions of dollars annually and is even more devastating in developing countries, could hold the key to developing an effective vaccine against the disease. In the July issue of Vaccine, UF veterinary scientists report sequencing the genes of multiple strains of the bacteria from across North America to identify common substances that could be candidates for vaccine development. Anaplasma bacteria infect red blood cells and are estimated to cost the cattle industry $300 million a year, according to industry estimates. Sick animals may develop a fever, have difficulty breathing and may be anemic. Thirty percent of the animals that contract bovine anaplasmosis die.

MRSA may not be the bully of the gym after all
 
01:39
GAINESVILLE, Fla. --- A sweat-drenched treadmill seems a likely haven for germs to set up housekeeping, including the dangerous antibiotic-resistant bug MRSA. This is one of the reasons why most fitness centers sanitize equipment and supply members with antibacterial wipes. But these aggressive cleaning policies may not actually be necessary to prevent the spread of community-acquired form of methicillin-resistant Staphylococcus aureus, according to a new University of Florida study published today (March 3) in the American Journal of Infection Control. UF researchers found no trace of MRSA on fitness equipment or even floor mats in three community gyms, where they collected samples. This finding supports the notion that MRSA may be more likely to pass from skin to skin than from surfaces to skin, says Dr. Kathleen Ryan, a clinical assistant professor of pediatrics in the UF College of Medicine. "We have an increasing incidence of MRSA in the community, and we are looking for the sources of infection," Ryan said. "The assumption was we would find a lot of MRSA on the equipment, and if people have an abrasion on their skin, that contact could lead to infection. "This is very surprising." According to the Centers for Disease Control and Prevention, about 30 percent of people carry Staph bacteria on their bodies; however, only 2 percent have MRSA, which is resistant to many common antibiotics. The community-acquired form of MRSA accounts for about 14 percent of cases, and children and athletes are more likely than most people to become infected, according to the CDC. The researchers tested 240 samples collected from equipment housed in three area gyms, including a university gym, a community fitness center and a high school gym. They swabbed the equipment at different intervals, capturing samples on places people are more likely to touch, such as handles. They specifically looked at cardio machines, barbells, benches and weight machines. "All the gyms have a high user rate," Ryan said. "If (MRSA) had been there we believe we would have found it. "People have almost gotten to the point where they don't want to touch anything anymore. I think we can relax a little. I don't think we need to feel like everything we touch is some bad thing that is going to give us disease." Researchers strategically selected three gyms to test in order to represent a cross section of the community and to collect samples from equipment in centers with different policies and procedures. The high school, for example, did not provide sanitizing wipes to students who used the equipment as the university and community center did, Ryan said. Although being continually touched by sweaty people seems like it would beckon bacteria, it may be that the hard surfaces of gym equipment just don't provide an enticing enough environment for germs to set up long-term residence. "Bacteria can grow on a lot of surfaces but they need a substrate to grow on, like oils and other proteins and skin. It may be that solid surfaces just don't have enough stuff on them," Ryan said. "A couple studies found MRSA in wetter areas around sinks and on towels." While the study provides reassurance that some surfaces and areas may not harbor the high levels of contamination that people imagine, Dr. Aaron Milstone, of Johns Hopkins University, cautions that more sensitive testing measures may reveal lower levels of MRSA contamination on gym surfaces.

$1 million from 'Tyler's Hope' helps UF tackle disabling brain disorder
 
01:44
With the help of $1 million from Tyler's Hope for a Dystonia Cure Inc., a new research center is being established and a leading scientist has joined the University of Florida to confront a disease that has disabled a half million Americans. Yuqing Li, Ph.D., whose research has already played a part in current clinical testing to repurpose a commonly prescribed antibiotic to treat dystonia, has been recruited from the University of Alabama-Birmingham and is now a professor in the department of neurology at the UF College of Medicine. Along with clinical researchers at the existing Tyler's Hope Center for Dystonia Care at UF's Center for Movement Disorders and Neurorestoration, Li will investigate causes and potential treatments for a malady that is not well-known outside of the dystonia community, even though it is the third most common movement disorder behind Parkinson's disease and tremor. "UF already has the best neurosurgeons and neurologists in the world working on this problem. The role of Tyler's Hope is to bring a dream team together to cure a disease that has affected not only my children, but thousands of other kids," said Richard A. Staab, president of Tyler's Hope for a Dystonia Cure. "We want to provide support so the best and brightest researchers work side by side, focused on a single goal, without being distracted by administrative or nonproductive responsibilities." Tyler's Hope is named for Staab's son, who unexpectedly began having movement problems when he was 7. Tyler was diagnosed with DYT1 dystonia, named for the first gene mutation that scientists linked to the disorder. Later, Tyler's sister, Samantha, was also diagnosed with DYT1 dystonia — the type Li primarily studies. The gift will establish a Tyler's Hope Dystonia Research Laboratory to work in conjunction with the Tyler's Hope Center for Dystonia Care. "We are grateful to the Staab family and Tyler's Hope, and are excited Dr. Li has joined our faculty," said Michael Good, M.D., dean of the College of Medicine. "It is through private support such as that provided by Tyler's Hope that will allow us to move from being very good to becoming one of the nation's best medical centers." Dystonia causes prolonged, involuntary muscle contractions. In some instances, muscles that normally tighten and relax in harmony work against each other, causing the body to twist into abnormal, often painful postures. The contractions may strike a single muscle or a group of muscles, such as those in the arms or legs. No part of the body is off limits — even the neck, eyelids, face and vocal cords are susceptible. Scientists suspect neurotransmitters responsible for brain-muscle communication are being scrambled. But beyond that, little is known.

Michele Markant is a healthy-looking mother of six and a registered nurse — not the kind of person most would suspect of a drug addiction. But, as they say, looks can be deceiving. In 2009, authorities arrested Markant at her attorney's office for forging prescriptions, each instance a felony, to feed her addiction to painkillers. "I had been writing and calling in my own prescriptions for opiates for about two years," Markant says. Her addiction goes back 11 or 12 years, she says, and stems from a shoulder injury she sustained at work that led a doctor to prescribe painkillers. After a while, Markant couldn't get enough of the pills, and she developed an addiction that escaped the notice of her friends, family and colleagues.

Vibration helps reduces pain in chronic sufferers, UF researchers find
 
01:25
GAINESVILLE, Fla. — Rubbing or massaging is often an instinctive response to pain. Now researchers have found that another kind of touch, vibration, can also help reduce certain types of pain by more than 40 percent. The researchers are encouraged by the prospect that vibration therapies could bring pill-free pain relief to chronic sufferers. "The vibration truly represents an analgesic effect," said Roland Staud, M.D, a professor of rheumatology and clinical immunology in the University of Florida College of Medicine. "This is exciting because it is something that provides pain relief that is not associated with great cost." The findings are described online and in an upcoming print edition of the European Journal of Pain. Naturally occurring mechanisms help to blunt the severity of pain signals sent to the brain, but effectiveness of those systems varies from person to person, and in some people they fail altogether. Previous studies have shown that individuals with pain disorders of unknown cause — including fibromyalgia, migraine and irritable bowel syndrome — are less efficient at inhibiting pain. To study chronic pain, one therapy that researchers use, ironically, is to subject individuals to pain of a different kind. The treatment is somewhat effective, but has its downside. "It is, of course, very unappealing for patients," Staud said. The UF researchers decided to see how well a less painful kind of therapy might work. First, they applied pain-inducing heat to the forearms of participants, some of whom had fibromyalgia, some of whom had head and neck pain and some who were pain free. The researchers then used a special motor to deliver a high-frequency vibration to the skin and deep tissues of the arm to see whether that would relieve the pain caused by the heat. It did. All three groups of patients experienced 40 percent reduction in pain when the vibration was applied. "This is the first time a nonpainful stimulus has been found to have such an effect in fibromyalgia patients," Staud said. The results differ from previous findings showing that chronic pain sufferers have defective pain relief mechanisms that defy therapy. So what led to pain relief in the study participants? Was it because the vibration provided a distraction from the pain? Or was it truly a change in the pain signals being transmitted to the central nervous system? It turns out that about half of the participants were, in fact, distracted by the vibration — but that didn't matter. People who weren't distracted had the same level of pain relief as those who were distracted, the researchers found. To see whether the location of vibration affected pain relief, the researchers applied heat pain and vibration to the same arm in one set of experiments, and applied heat to one arm and vibration to the other in another set of tests. Pain relief was greater when the vibration was applied to the same arm subjected to heat, compared with when the heat and vibration were applied to different arms. "Dr. Staud and his colleagues have conducted a novel and innovative study that strives to drill down on the potential mechanisms that differ or do not differ between healthy people and chronic pain patients," said Claudia Campbell, Ph.D., an assistant professor of psychiatry and behavioral sciences in the Johns Hopkins School of Medicine. Results from various types of animal studies, including brain studies, suggest that vibration might interfere with transmission of pain signals from various parts of the body to the central nervous system. The current study indicates that even in people who experience chronic pain, some mechanisms for decreasing pain intensity are still in working order, but don't spring into action when needed. "They have this capacity," Staud said. "What we don't understand is why they have problems using it."

UF&Shands leaders joined with former University of Florida football coach Urban Meyer and his wife, Shelley, today to mark the opening of the new Chest Pain E.R. at Shands. Shands at the University of Florida's new Chest Pain E.R. Photo By Jesse Jones The Archer Road facility, located within the Shands Critical Care Center Emergency Department at Shands at UF, includes eight beds devoted to patients with low to moderate chest pain or other symptoms of a heart condition and represents a more focused, patient-centered approach to emergency cardiac care. Patients will have immediate, around-the-clock access to UF cardiologists, emergency medicine specialists and specially trained mid-level practitioners in a center that is designed to optimize their evaluation and treatment. "When people come through the doors of our Chest Pain E.R., they are the center of attention from a highly trained team of professionals dedicated to helping them get well," said David S. Guzick, M.D., Ph.D., UF senior vice president for health affairs and president of the UF&Shands Health System. "Patients with symptoms of a heart attack receive great medical care, with compassion. We understand that they are anxious about their symptoms, so we want to quickly provide answers and put them back on the road to good health." The goal is to evaluate patients within 10 minutes of their arrival, according to Preeti Jois, M.D., an assistant professor of emergency medicine and the Chest Pain E.R. medical director. An interdisciplinary team of emergency medicine specialists and cardiologists will quickly make a diagnosis and deliver appropriate treatment.

Programs may prevent tooth decay in tots
 
01:43
GAINESVILLE, Fla. — A toddler's tiny teeth are destined to fall out in later years as their permanent pearly whites grow in. But for some children, especially those from low-income families, cavities and poor oral health lead to complicated dental problems long before they even graduate from their cribs. Programs designed to incorporate tooth decay prevention as part of a child's regular checkup with the doctor could be a big step toward improving infants' and toddlers' dental health, say University of Florida researchers, who received a $293,000 grant from the National Institutes of Health to study whether such programs in Florida and Texas are actually improving dental care in young children enrolled in Medicaid. The American Academy of Pediatrics, the American Dental Association and the American Academy of Pediatric Dentistry recommend children visit the dentist for the first time by age 1, but many children do not receive preventive dental care until they are much older, if at all, said UF health economist Jill Boylston Herndon, Ph.D., the principal investigator on the two-year grant. "There is also this attitude that baby teeth are not that important," said Frank Catalanotto, D.M.D., a professor of pediatric dentistry in the College of Dentistry who advocated for Florida to establish a program targeting early childhood caries. "But the reality is getting a cavity in a baby tooth can lead to an infection. And, in fact, several children have died over the last several years in this country of an untreated dental infection. "The tragedy of this is that it is relatively easy to prevent early childhood caries with some simple measures of just toothbrushing using a fluoridated toothpaste, not putting a baby to bed with a bottle, and a dental visit with an application of a fluoride varnish," added Catalanotto, a co-investigator on the grant.

UF researchers find social hookah smoking packs a carbon monoxide punch
 
01:38
GAINESVILLE, Fla. — A new University of Florida study shows that patrons leaving hookah cafés had carbon monoxide levels more than three times higher than patrons exiting traditional bars. Carbon monoxide reduces the blood's ability to carry oxygen to tissues, and long-term exposure has been linked to cardiovascular disease. The UF study results appeared in the March issue of the American Journal of Preventive Medicine. The social nature of hookah smoking, which is often shared in groups, makes it appealing to young people, said lead researcher Tracey Barnett, Ph.D., an assistant professor in the UF College of Public Health and Health Professions' department of behavioral science and community health. "There is also a common misperception that hookah smoking is a harmless alternative to cigarette smoking," she said. Hookah pipes are composed of a head, where lit charcoal and tobacco sit, a body with water bowl, and a hose. Air is drawn through the tobacco and into the pipe body, where it passes through the water before being inhaled through the hose. A study led by Barnett showed that 11 percent of Florida high school students and 4 percent of middle school students surveyed in 2007 had tried hookah smoking. It is especially popular among college students. A University of Memphis study estimated that 10 percent to 20 percent of some young adult populations are current hookah users. The new UF study is the first to measure carbon monoxide levels of hookah smokers "in the field." "Our study is unique because we were actually getting participants as they were leaving these establishments," Barnett said. "There's been a lot of great lab work on hookah and carbon monoxide levels, but doing a behavior in the lab is not the same as when young adults are out with their friends in an environment where there's also drinking and socializing, so with this study we were catching them in a real-world moment as best we could."

UF launches construction of new Clinical and Translational Research Building
 
01:27
Saying that the planned Clinical and Translational Research Building at UF will be a "a huge boon to our research efforts and our preventive health activities," UF President Bernie Machen and other officials broke ground for a new home for research that will speed scientific discoveries to patients. "For the first time clinical research infrastructure will be brought together with clinical research programs under one roof," said David S. Guzick, M.D., Ph.D, senior vice president for health affairs and president of UF&Shands Health System. The $45 million, 120,000-square-foot complex is expected to be completed early in 2013. Barbara Alving, M.D., director of the National Center for Research Resources, National Institutes of Health, was a special guest at the groundbreaking. "The CTRB will foster collaboration learning and discovery across multiple disciplines," said David R. Nelson, M.D., director of the UF Clinical and Translational Science Institute. Architectural design, engineering, manufacturing and construction is being carried out by Perkins + Will, Moses and Associates, AEI, SEG, Siebein and Associates, Skanska, Brame Architects, Williams-Scotsman and Brentwood Company. "This center will really translate to better research and better outcomes for our seniors," said Marco Pahor, M.D., director of the UF Institute on Aging.

Lauren's Angel
 
03:46
In fall 2008, Lauren Ault was admitted to Shands Rehab Hospital after undergoing a series of complicated brain and stomach surgeries to remove a brainstem tumor. Almost immediately, Megan Molyneux, OT, Shands Rehab Hospital occupational therapist, felt a connection with the young woman. "She was only a couple of years younger than me," Molyneux said. "I came to know that she has such a loving spirit." In Ault's two months at Shands Rehab Hospital, she and Molyneux formed a remarkable bond. Molyneux worked with Ault to get ready in the mornings, helping with her hair and make-up. "We wanted her to feel like a normal 20-something," Molyneux said. At the time, Molyneux was pregnant with her son, and Ault was excited about the new baby on the way. "She would rub my belly every day and ask me how I was doing," Molyneux said. "After my son was born, I brought him here to see Lauren. That was our first outing!" Time went on, and when Ault was discharged, Molyneux was determined to be her champion and companion. She started a group called Lauren's Angels, which is dedicated to raising funds for improvements to Ault's home. Shands Reha b Hosp ital | Serv ice Therapist provides angelic care for rehab patient "I think Lauren is the most selfless person," Molyneux said. "She is always concerned with everyone around her and shows little worry about herself. I am inspired by that." Molyneux has worked tirelessly to build awareness about Ault's situation. She has created a Facebook page, a Web site, talked to local media and secured publicity through TV stations, newspapers and radio stations. Molyneux also was instrumental in organizing a special 5K walk/run in September to help raise money for Ault and her family. "The story here is about Lauren's tremendous progress and her road to recovery," Molyneux said. "I just want to be her friend. I want to help her move on with her life, and I want to encourage her to be brave." Molyneux's father spent time in the hospital when she was younger, and it was then that she learned how vulnerable people feel when they are in a hospital environment. "That's why I chose to do what I do; I want patients to feel loved," Molyneux said. "I want to help people. I want to be their advocate, and I want them to know that they are not alone. This isn't just a job... it's my calling."

UF cardiologists study gene-modified stem cells to help Dobermans with common heart condition
 
01:52
Expanding earlier research, University of Florida College of Veterinary Medicine cardiologists have begun a pilot study using adult stem cells to repair heart function in Doberman Pinschers with a common heart condition. Researchers hope to build on their results to further explore the technique in other breeds of dogs. "Our goal would be to try to regenerate and bring new muscle cells into the heart," said Amara Estrada, D.V.M., an assistant professor and chief of the UF Veterinary Medical Center's cardiology service. The Doberman Pinscher Club of America has provided $72,000 for Estrada's team to study up to 15 dogs with early-stage dilated cardiomyopathy. A common disease of the heart muscle, DCM affects both dogs and people. Although people may benefit from aggressive therapy, such as heart transplants or ventricular-assist devices, medical therapy is the only current treatment option for dogs afflicted with the disease. At best, however, such treatment only prolongs the inevitable. "When a person gets this disease and their heart fails, they typically go on a list to receive a transplant," Estrada said. "But when our patients get it, they are done." Procedures such as open heart surgery or ventricular assist devices would be cost-prohibitive for most animal owners, Estrada said. "If this technique works, it would provide an affordable treatment option and one which never existed before," she said. "People wouldn't have to watch their dogs suffer." Dobermans are afflicted with DCM more frequently than any other dog breed, and experience extremely high mortality rates. Most Dobermans with this condition die within six months. "Other breeds of dogs with this condition do not have as rapid a course, but do eventually succumb due to refractory heart failure," Estrada said. Judith Brown from the Doberman Pincher Club said she heard Estrada's name mentioned by another researcher with an interest in DCM. Brown contacted Estrada right away. "This disease is an enormous problem in our breed," she said. "We are all losing dogs because of it. We have been looking for some time for a viable study to donate funds, and which we could really believe in," Brown said. "I feel like if you are going to donate to anything, you might as well make a difference." Brown said she had spoken to a lot of investigators, but was immediately impressed with Estrada. "Our dogs are dropping dead in front of our faces," Brown said. "Dr. Estrada had the empathy and understanding of what we're dealing with. A lot of people don't seem to get it, but she did."

The Night of Champions benefit at the University of Florida
 
01:58
More comprehensive, patient-focused care would vastly improve the lives of Parkinson's patients, according to Rasheda Ali, an author and advocate in the fight against Parkinson's disease. Ali will champion an approach that places patients in the center of a spectrum of care during "The Night of Champions," an event to benefit the University of Florida Center for Movement Disorders and Neurorestoration, on May 25. The daughter of one of the most recognized men in the world — boxing great Muhammad Ali, who was diagnosed with Parkinson's in 1984 — Rasheda Ali says health care services for patients need to advance beyond an antiquated model of disconnected appointments at doctor's offices, hospitals, therapy sessions and diagnostic facilities. She endorses the approach being pioneered at the Center for Movement Disorders and Neurorestoration, where caregivers from more than a dozen specialties combine under one roof to meet the physical and emotional needs of patients and families.

Former Attorney General Reno helps UF open Center for Movement Disorders and Neurorestoration
 
01:57
GAINESVILLE, Fla. — "My sister Janet Reno has Parkinson's. My younger brother has Parkinson's. I have essential tremor. Sometimes we would all shake in unison." So said Maggy Hurchalla, a former Martin County, Fla., commissioner who talked about her family's experience with Parkinson's disease at the opening Monday of the University of Florida's new Center for Movement Disorders and Neurorestoration. With her sister, former U.S. Attorney General Reno, at her side — along with UF College of Medicine Dean Dr. Michael Good and center co-directors Dr. Kelly Foote and Dr. Michael Okun — Hurchalla recalled when "Janny" publicly announced in 1995 that she had Parkinson's disease. That same day, Hurchalla spoke at a large dinner attended by many seniors. Some confided that they admired her sister's courage. They also had Parkinson's, but were afraid to even tell their children. Reno worked for five more years as attorney general. She served longer than any other attorney general in the 20th century. "Her hand shook like mad, but she pointed out that her brain wasn't shaking," Hurchalla said. Hurchalla and Reno on Monday toured UF's new center, a destination where people with Parkinson's disease, dystonia, tremor, movement problems and ataxia have access to the latest research-based care and the opportunity to shape the therapies of tomorrow.

Looking at the image now, Kim Harris sees the violet tinge to his wrinkly skin, a subtle hint that all was not well inside his six-pound body. At the time, she thought all newborns must look like that That night Kim and her husband, Danny Harris, sent Caleb to the nursery so they could get some much-needed rest. The decision likely saved his life. "They came in the room and said he wasn't breathing," Kim said. "Something was wrong with his heart." Kim and Danny Harris with their newborn son, Caleb, shortly after learning he would need a heart transplant./Photo courtesy of the Harris family Kim and Danny Harris with their newborn son, Caleb, shortly after learning he would need a heart transplant. Photo courtesy of the Harris family Just 16 hours old, Caleb was rushed from Ocala where he was born to Shands at UF, where doctors with UF's Congenital Heart Center diagnosed him with hypoplastic right heart syndrome. The right side of his heart was not fully developed. Medicine kept his heart working, but doctors said the infant would need a heart transplant. "I just cried," Kim said. "I just remember being very scared because I did not think he was going to live to get a new heart." Caleb, born a few days before Christmas, spent the first four months of his life in Shands at UF, hooked to tubes and machines, undergoing open-heart surgery and countless tests. It wasn't what Kim or Danny had in mind for their little boy. No one does. "We had planned on having Christmas dinner here," Danny said. "I had put a million lights up all around the house. When this happened, I said 'I am going to keep all the lights up until he comes home.' And I did." At the hospital, Kim, who stayed with Caleb when Danny went back to work, relied on the nurses in the NICU and PICU. They cried with her when she cried, hugged her when she needed it and took care of Caleb when she couldn't be by his side. "I would come in and I would see some of them just rocking him. It meant so much more. It felt like he had 20 moms," Kim said. Caleb Harris is now 16 months old and thriving./Photo by Jesse S. Jones Caleb underwent open-heart surgery when he was 3 months old, alleviating the immediate need for a heart transplant. A month later he was strong enough to go home. Caleb Harris is now 16 months old and thriving./Photo by Jesse S. Jones/University of Florida Now 16 months old, Caleb is thriving. He has taken his first steps and loves Mickey Mouse and typical toddler mischief, like getting into kitchen cabinets. She keeps in touch with several of the nurses she met and makes time for a visit or lunch when she and Caleb are in for doctor's appointments. "It makes us feel great. It makes us feel like what we do matters to parents, to the patients, to the families as a whole," said Erin Murray, R.N., a nurse who cared for Caleb in the PICU. Kim keeps Caleb's cardiologist, F. Jay Fricker, M.D., chief of pediatric cardiology, on speed dial, too. "I talk to Dr. Fricker a lot. We joke because now when I call he knows who I am. He knows me as 'Kim' now instead of 'mom.' He is great." Looking to the future, Kim and Danny's dreams for Caleb are a lot simpler than they were when she was pregnant. She just really wants one thing for him. "Now I just want him to be healthy," she said. "I just want him to live a long, happy life."

Monthly treatments at UF keep tiny horse on its feet

Categories: Colleges Research Institutes Shands Healthcare Health in a Heartbeat The Post Events Multimedia Monthly treatments at UF keep tiny horse on its feet By Sarah Carey • Published: June 28th, 2011 Category: College of Veterinary Medicine, Slideshow, Top Feature, Video Jody Schaible, UF's Large Animal Hospital's farrier, talks to Debbie DeHowitt, Buttercup's owner, in the Large Animal Hospital recently. (Photo by Maria Farias/University of Florida) Big things really do come in small packages, if you ask Debbie DeHowitt, whose horse-loving heart belongs to the "mini-minis." DeHowitt's 4-year-old mini-miniature horse, Buttercup, has been a client of the UF Large Animal Hospital from an early age, when it became clear that she needed special care for hoof problems. "When she was 6 or 7 months old, I became aware that she was starting to walk on the outside of her front hooves," DeHowitt said. Her veterinarian had a farrier — someone whose job is to make horseshoes and fix there hooves — create extensions to widen Buttercup's hooves to fix the problem. At first, the extensions seemed to work, but eventually Buttercup's condition worsened. DeHowitt made a five-hour trip to UF from her home in Hollywood, Fla., to explore possibilities for further treatment. Surgery was ruled out so Buttercup began what would become a part of her health maintenance routine -- visiting UF's farrier, Jody Schaible, every month for the next three years for corrective hoof care. "Jody has been great to us," DeHowitt said. "Over the years, he has had to switch from pre-made shoes to different materials to extend her hooves and keep her comfortable. Without Jody, I know that Buttercup would not be turning 4 later this month." Schaible said working on Buttercup had been a challenge from the start. "I have to take into consideration that her feet are extremely small. If you held a quarter on the bottom of her foot, the quarter would cover 95 percent of her foot, so nailing shoes is out of the question." Buttercup needs special glue-on shoes that only attach to the outside of her foot to provide support to her leg, Schaible said. "The other problem is that she cannot stand on one leg to glue on the shoes, so we are forced to sedate her and lay her on her side, then work on one foot, flip her over and repeat the process again on the other foot," he said. "It's a labor of love and Buttercup has become a very important part of the UF family."

UF scientists devise way to sort brain cells for potential transplants
 
01:31
University of Florida scientists have discovered a way to separate the neural wheat from the chaff during the process of generating brain cells for potential patient therapies. The technique, recently detailed in the online journal PLoS ONE, could be applied to long-awaited stem cell treatments for Parkinson's disease, spinal cord injuries and other brain disorders. It would allow doctors to deliver neurons to patients, without including vast amounts of other types of unnecessary brain cells. "We need to be able to deliver precise doses of our therapeutic drug, which in this case is neurons that are needed to restore function lost as a result of disease or injury," said Brent A. Reynolds, Ph.D., a professor of neurosurgery with UF's Evelyn F. and William L. McKnight Brain Institute. "Prior to the development of our technology, it was not possible to deliver highly pure populations of neurons, or to control the number of neurons that were delivered." For more than a decade, scientists and policymakers have pursued the idea of using stem cells to restore vitality in patients with brain diseases or injuries. The therapeutic stem cells can come from a variety of sources, including controversial embryonic and fetal tissue or, in this application, noncontroversial adult brain tissue.

UF researchers find surgical breast biopsies overused in Florida
 
01:37
Thousands of women receive unnecessary surgical breast biopsies in Florida each year, University of Florida researchers state in an article published online this week by the American Journal of Surgery. These surgeries carry greater health risks and are more expensive than a less invasive, equally effective procedure called a needle biopsy. "Open surgical biopsy is not accounting for 10 percent or 5 percent of initial breast biopsies, which is what's recommended," said Luke Gutwein, M.D., a surgical resident in UF's department of surgery. "It's accounting for 30 percent of initial breast biopsies, so open biopsy is incredibly over-utilized." Gutwein and six other UF researchers analyzed state public health data for the years 2003 to 2008 and found that about 30 percent of breast biopsies were performed through open surgery. The study reflects conditions outside Florida, too, said David P. Winchester, M.D., a professor of surgery at NorthShore University HealthSystem in Evanston, Ill., and a former chairman of the National Accreditation Program for Breast Centers. "This is an important message and should be generalizable to other parts of the country, in terms of the desirability of using minimally invasive biopsy techniques," he said. Needle biopsies are usually more appropriate when the suspicious area can be seen clearly through imaging techniques, according to reports written by panels of breast health specialists. The procedure, typically performed by radiologists, requires inserting a needle through a tiny incision into the suspicious area and extracting tissue samples through the needle. The radiologist monitors the procedure via ultrasound or mammography as it takes place.

Parents play a powerful role in predicting DUI
 
01:24
GAINESVILLE, Fla. — Sipping the occasional glass of wine may seem relatively harmless, and could even be beneficial to the drinker's health. But for parents, even moderate drinking can result in one unintended consequence: an increased risk their children will drive under the influence as adults. Writing in the current issue of the journal Accident Analysis and Prevention, University of Florida researchers found that about 6 percent of adolescents whose parents drank even sporadically reported driving under the influence at age 21, compared with just 2 percent of those whose parents did not imbibe. "The main idea is that parents' alcohol use has an effect on their kids' behavior," said Mildred Maldonado-Molina, Ph.D., an associate professor of health outcomes and policy with the UF College of Medicine and the lead author of the paper. "It's important for parents to know that their behavior has an effect not only at that developmental age when their kids are adolescents, but also on their future behavior as young adults." It's typical for parents to worry about the influence of their children's friends and peers, and the study shows that peer behavior can have an effect, particularly on kids who aren't exposed to alcohol at home. Having friends who drink alcohol was a risk factor for driving under the influence for teens whose parents did not drink. Also, kids whose parents and peers consumed alcoholic beverages were especially at risk for driving under the influence. About 11 percent of these teens reported driving under the influence in their 20s.

Patient privacy should be respected abroad and online
 
01:29
Taking an unauthorized photo of a patient and posting it on Facebook is a giant no-no for health-care providers, who follow strict federal guidelines protecting patient privacy. But what if the patient is a little girl in Ecuador receiving a vaccine from an American medical student, who's in the country on a medical outreach trip? Although taking photos of patients in developing countries and posting them on the Web may not be illegal, it's not ethical, say researchers from the University of Florida. It's long been a common practice for health care providers to snap photos while volunteering their time in developing countries, generally to bring back evidence of the conditions patients face there. But reporting in the Journal of Medical Internet Research, UF College of Medicine researchers say providers should treat patients' privacy with the same reverence no matter where the care takes place. "A medical student would not take a picture of a patient in clinic here and post it on Facebook," said Erik Black, Ph.D., an assistant professor of pediatrics with the UF College of Medicine and one of the lead authors of the paper. "But there is a disconnect on these trips. We are not respecting these people as individuals. If we are not going to respect them in the same way we respect patients in the United States, why are we even going?" UF researchers examined the Facebook profile pages of 1,023 medical students and residents, finding no breaches of patients' privacy in the United States. But they did find 12 photos depicting patient care in developing countries. Every year during spring break, students from all health fields fan out across the globe to work in clinics in medically underserved nations, such as the Dominican Republic, Haiti and Ecuador. For students, who work closely with faculty mentors on these trips, it's a chance to get hands-on experience in a patient-care setting and help people who sometimes travel for days in search of care.

University of Florida researchers have modified a toxic chemical produced by tiny marine microbes and successfully deployed it against laboratory models of colon cancer. Writing today in ACS Medicinal Chemistry Letters, UF medicinal chemists describe how they took a generally lethal byproduct of marine cyanobacteria and made it more specifically toxic — to cancer cells. When the scientists gave low doses of the compound to mice with a form of colon cancer, they found that it inhibited tumor growth without the overall poisonous effect of the natural product. Even at relatively high doses, the agent was effective and safe.

UF students, employees find good things in small packages this flu season

With a grimace and a grip on her friend Jayce Victor's hand, Whitney Hughes bared her arm for a flu vaccine injection. "I'm so scared, I'm a baby," said Hughes, a sophomore studying political science. "I usually get the nasal spray." In a matter of seconds, Margaret Berry, R.N., a registered nurse from the UF Student Health Center, finished administering the shot via a new method that uses a much shorter needle than usual and delivers the vaccine into the skin rather than into muscle. That potentially means less discomfort as well as less vaccine used to provide the same level of protection against the flu as a traditional injection.

Winter chills couldn't keep a handful of southeast Gainesville parishioners away from church one dreary evening in January. They didn't want to miss their time of fellowship. "We have some sweet potato pie here, macaroni and cheese there and some collard greens and some dressing back here," Trollyn Gillins said to the group. "So we have to get all of that off," she added, pointing to her stomach, back and sides. For an hour, Gillins, 49, led the group through a series of jumping jacks, leg lifts, crunches and other moves she had learned from another church member at Open Door Ministries. In the year since she started going to church to exercise, Gillins has been able to stop taking one of her two blood pressure medicines, on the recommendation of her doctor. Before, she used to get exhausted easily, but now she can walk 3 miles with ease and line dance for more than an hour. Now, thanks to a $600,000 grant to the University of Florida and Florida A&M University, more people like Gillins will gain skills and knowledge that can help them take charge of their health. The award, from the State University System Board of Governors, funded the launch of the Community Health Workers Training and Research Institute, which seeks to help people improve their health while acquiring marketable skills that can be translated into job opportunities within the health care field. The institute will train people to become community health workers who can educate themselves and others about healthful behaviors. That will increase the supply of health workers and boost the chances for unemployed, underemployed or disabled persons to find work, particularly in rural, medically underserved areas with high proportions of ethnic minorities.

'UF&Shands at Springhill' to offer specialty care in northwest Alachua County
 
01:32
UF&Shands leaders today joined with Alachua County Commissioner Lee Pinkoson to break ground for "UF&Shands at Springhill," a new facility that will house University of Florida Physicians specialty practices in neurology, cardiology, psychiatry, dermatology and women's health. The new facility, located off Interstate 75 Exit 390 near Northwest 39th Avenue and Northwest 89th Boulevard, is scheduled to open in January 2013. Clearing the site and constructing the new four-story, 111,600-square-foot facility represents a $35.5 million investment, officials said. "This is another example of how UF&Shands is reinvesting in Alachua County," said David S. Guzick, M.D., Ph.D., UF senior vice president for health affairs and president of the UF&Shands Health System. "By grouping specialty practices here with existing facilities like Shands Vista and Shands Rehab Hospital, we are building a northwest campus of UF&Shands. We expect to add specialty services here as the campus develops, creating a medical hub that provides needed, quality health care while stimulating the area economy." The campus will offer services in one of the fastest growing areas of the county, officials said.

A large clinical study of painful jaw problems commonly known as TMD disorders has revealed a wide range of findings, including how women apparently grow more vulnerable to the condition as they age. Writing in the November issue of the Journal of Pain, a multi-institutional team of researchers including scientists with the University of Florida College of Dentistry, revealed the results of the Orofacial Pain Prospective Evaluation and Risk Assessment study, or OPPERA. One of the largest clinical investigations into the causes of what are technically known as temporomandibular joint disorders, or TMD, researchers hope the discoveries may lead to new methods of diagnosing and treating facial pain conditions, and predicting who will be susceptible to them.

Urban Meyer helps open new Chest Pain E.R. at Shands at UF
 
01:19
He woke up at 4 a.m., his hand clasped to his chest. He tried to stand and tumbled to the floor. Shelley Meyer's voice quickens as she recalls that moment in December 2009, when she dialed 9-1-1 fearing something was seriously wrong with her husband, Urban Meyer, then coach of the University of Florida football team. Meyer was rushed to Shands at UF. "I was really scared it might be his heart," Shelley Meyer said, speaking to a crowd gathered at Shands at UF Wednesday to celebrate the grand opening of the new Chest Pain E.R. "I'm really happy to hear that if we had come here tomorrow, he would be taken to the exact right place ... and that, as a wife of a patient, is very comforting to know." Meyer, whose health issues have received much publicity, did not suffer a heart attack in 2009 when he came to Shands. He said he remembers being both relieved when doctors told him it was not a heart attack, and also frustrated by not knowing what was causing the intense chest pain he felt. He would later learn the problem was esophageal spasms.
