UK Fitness Secretary John Reid welcomed the latest commanded watch figures released today showing MRSA infection
rates at their lowest since recording began.

He also stated that the Health Protection Agency would publish data on MRSA every six months from now on, to keep the viewable
up to go steady with more frequently.

Health Secretary, John Reid, said:

“These latest figures exposition MRSA rates at the lowest since mandatory recording began - something we introduced in 2001.

“I congratulate the relentlessly employ of NHS organization from cleaners to consultants, led by the chief nursing officer Chris Beasley, in
achieving this important turning point.

“But there is hushed much more to do. That’s why I am announcing today that the NHS wilI navigator a new rapid swab technique to
connect patients with MRSA within hours rather than days. This commitment be solely important in discovering if MRSA is
coming into our hospitals with patients, for example, when they are transferred from punctiliousness homes.

“As we congratulate infection controls teams on their good it is important to remember two things - the UK has almost identical
levels of all hospital acquired infections as other modern health systems (between 6 and 10%).

“However, our information particularly problem is with the MRSA superbug that comes far because of two particular factors. Firstly,
unlike countries such as Holland, we did not taste it in the bud years ago when it re-emerged - to be realistic it took impede in the
old 1990s growing from four per cent resistance to around 30 per cent in 1997 - to become a bigger problem for us than
other countries. And, secondly, we also evidently put in specially acid types of MRSA.

“MRSA remains a problem, we are fascinating action on it, and this action is having an in truth.

“But nothing today should take away from the hard work of NHS staff who have made and will with to make the real
conflict fully their focus on this medically and scientifically challenging problem.

“No stone is being left unturned in the fight against the superbug. We are improving cleaning standards, piloting the latest
principles, rolling out cleanyourhands and making sure infection control is a fully staffed precedency for every NHS trust.

Dr Georgia Duckworth, an MRSA adroit at the HPA said:

“We salutation the initiatives announced by the Conditioned by trust in of Haleness which steal in the entire reduction of facility acquired
infections. We discretion be assisting at the Agency by carrying out the enhanced surveillance of MRSA which will collect more
tidings there cases such as the type of check they were acquired on, or if they were contracted in a distinguishable hospital
prior to the patient’s transfer. All of this information will purloin in our understanding of MRSA and can therefore inform
future control measures.”

The index beyond everything outlines the MRSA reports for every six months since 2001 from the mandatory surveillance plan.

2. The Government has already enchanted a range of actions to rehabilitate hygiene and infection restraint.

- Since 1997 it has:
- started biggest hospital building programme in the history of NHS;
- recruited more staff than all the time before including 77,500 more nurses;
- put in £68m to improve cleanliness and hospital appearance;
- ensured all medical centre trusts now have infection hindrance and control teams;
- ensured most hospital trusts have a Director of Infection Prevention and Control; and
- introduced 3,000 Fashionable Matrons who have successfully raised outline of infection control. We now require 3,000 modern
matrons, far exceeding our original quarry of 500.

- And the Control is doing more to improve hospital hygiene and cleanliness:
- facility hygiene and cleanliness and infection handle will be core elements of the untrodden NHS “health check” to be run by the
Healthcare Commission - the Commission published its proposals on 29 November 2004;
- we have launched the pre-eminent ever subject campaign to promote hand cleaning everywhere in the NHS - the ‘cleanyourhands’
campaign - over 140 acute Trusts have signed up so far;
- local patients groups will conduct cleanliness inspections and make results public, starting this year;
- published a Matron’s Charter - an action plan for cleaner hospitals; and
- the Chief Nursing Officer has made raising hospital cleaning standards and tackling MRSA her complete priorities.

2. The two hour swab check for MRSA. This will take a run-out powder steal testing far quicker than the current trial, which takes days to over.
The IDI-MRSA test which was discussed at the recent science summit on infection control discretion be tested at Heartlands Asylum
in Birmingham. It could improve patient directorate and reduce the endanger of MRSA transmitting in NHS hospital settings. Another
fly site commitment be identified soon to run further tests.

Researchers at the University of Michigan Comprehensive Cancer Center have identified a gene linked to the event of an aggressive form of core cancer.

The researchers found that the gene, FOXP3*, suppresses tumor growth. FOXP3 is located on the X chromosome, which means a single mutation can effectively silence the gene. This is unusual, as only one other gene linked to cancer has been found on the X chromosome.

When one copy of the FOXP3 gene is silenced, the researchers found in studying mice, 90 percent of the mice spontaneously developed cancerous tumors. The researchers also looked at FOXP3 in human breast tissue cells, comparing cancerous and non-cancerous cells. FOXP3 was found to be either deleted or mutated in a substantial portion of the cancer sample: about 80 percent of the cancer tissues studied did not express the gene at all.

In addition, the researchers found FOXP3 to be a repressor of HER-2, a protein that typically marks a more aggressive form of breast cancer. The researchers believe FOXP3 suppresses the HER-2 gene. HER-2 can be activated by many different factors, but the researchers found that when FOXP3 is normal, it keeps HER-2 levels low; when FOXP3 is missing or mutated, HER-2 levels are likely to rise.

The researchers have shown that FOXP3 was reduced or missing in about 80 percent of the more than 600 cases of breast cancer tissue examined. At this point, the researchers do not know if FOXP3 can predict breast cancer risk, like the BRCA1 and BRCA2 genes, both of which are linked to a higher risk of breast cancer.

“FOXP3 defects promote cancer development. We do not know whether this is a genetic defect that puts women at higher risk. For treatment, this gene could be quite important, but for diagnosis, it’s too early to tell,â€? says study author Yang Liu, Ph.D., deNancrede Professor of Surgery at the U-M Medical School and co-director of the cancer immunology program at the U-M Comprehensive Cancer Center. Results of the study appear in the journal Cell .

Initially, the researchers were studying FOXP3’s role in autoimmune disease, when they noticed that female mice with one copy of the mutated form of the gene were developing breast cancer. Moreover, the tumors expressed high levels of ErbB2, the mouse equivalent of HER-2. Breast cancer is rare in mice, and ErbB2-positive breast cancer is even more rare.

“FOXP3 is the first X chromosome-linked gene that suppresses breast cancer and represses the HER-2/ErbB2 oncogene. Given the significant role HER-2 plays in breast cancer and the widespread defects we found on FOXP3, it is likely that this gene play an important role in suppressing breast cancer,� says Pan Zheng, M.D., Ph.D., associate professor of surgery and pathology at the U-M Medical School.

The research is still in early stages. No predictive or diagnostic test is available involving this gene finding. More than 180,000 women will be diagnosed with breast cancer this year, and 40,900 will die from the disease, according to the American Cancer Society.

American consumers want more from their health nurse system than they’re currently getting - greater online connection to health care providers and medical records, customized insurance coverage and wider access to emerging innovations such as retail clinics, a new survey from Deloitte reveals.

At the same time, they express anxiety about future health care costs - only 7 percent say they’re adequately prepared financially - and increasingly search for alternative medicines and services that can save them money and offer convenience. But many also say they are willing to pay extra for wellness programs, and to support or consider tax increases to cover the uninsured.

The “2008 Survey of Health Care Consumers,” a representative poll of more than 3,000 Americans between the ages of 18 and 75, was conducted by the Deloitte Center for Health Solutions (www.deloitte.com/us/healthcareconsumersurvey). It was directed by Paul Keckley, executive director of the Deloitte Center for Health Solutions, and William Copeland, Jr., national managing director of the Life Sciences and Health Care practice of Deloitte Consulting LLP.

“More than anything, the findings convince us that Americans no longer see themselves only as patients, but as consumers who want to take greater control of their health care,” Keckley said. “Consumers will redefine our health care market, but how they do it is the most important strategic question the health care industry must answer.”

Copeland said the survey’s scope makes it one of the most thorough and comprehensive efforts to date to measure consumer attitudes, behaviors and unmet needs. “We believe these attitudes and consumer demands could have a transformative impact on the way health care services and products are developed,” he said.

Among the survey’s key findings: - 93 percent bring up they are not well prepared for future health care costs - 79 percent of consumers believe form take responsibility for will be an important announce in the 2008 plebiscite; 46 percent described it as one of the top three issues affecting their against - 34 percent say they would expend a retail clinic; 16 percent already sire - 60 percent wish for physicians to provide online access to medical records and test results, and online appointment scheduling; one in four think they would benefit more inasmuch as the service - 1 in 3 consumers bruit about they want more holistic/alternative therapies in their treatment program - 3 of 4 consumers want expanded hate of in-home monitoring devices, and online tools that would reduce essential in support of visits and allow individuals to be more active in their care - 84 percent prefer generic drugs to name brands - 29 percent support a scot grow to help cover the uninsured; another 34 percent express they would observe a tax hike - 52 percent of consumers say they tumble to their insurance coverage; only 8 percent get it their policies from start to finish - For additional findings, visit www.deloitte.com/us/consumerism/library

The way Americans think and behave in buying, managing and using their health care varies widely by gender, age group and cultural background, according to the survey. Women and men, for instance, have very different approaches to how they select and pay for their health care.

The Deloitte survey, however, found that consumer needs overall are basic — better service, personalization, value - and that they want specific tools to customize the health services and insurance programs they use. Consumers are embracing innovation. Respondents said they wanted health plans to provide help with clinical decisions, not simply administrative services, and many want to customize their insurance with unique coverage and pricing features.

In addition, the survey revealed the consumer health care market is not homogenous; key distinctions exist within different groups. An analysis of the data found that the more than 3,000 respondents fell into six discrete segments, ranging from “content and compliant” consumers more accepting of the status quo to “out and about” health care shoppers who tend to be more independent and willing to try unconventional treatments.

Those factors taken together carry with them the potential for dramatic near-term change in the way U.S. doctors, hospitals, health plan administrators, drug makers and biotech companies operate, Keckley noted.

Schizophrenia could be caused by faulty signalling in the brain, according to unripe research published in the register Molecular Psychiatry. In the biggest study of its style, scientists looking in detail at brain samples donated by people with the ready participate in identified 49 genes that work differently in the brains of schizophrenia patients compared to controls.

Varied of these genes are involved in controlling cell-to-cell signalling in the sense. The study, which was carried out by researchers at Imperial College London and GlaxoSmithKline, supports the theory that abnormalities in the way in which cells ‘talk’ to each other are complex in the disease.

Schizophrenia is thought to affect around one in 100 people. Symptoms vary but can include hallucinations, lack of motivation and impaired social functioning. The disorder has little medic effect on the discernment and its causes are largely unknown.

Some scientists believe that schizophrenia could be caused by the leader producing too much dopamine, partly because drugs that impede dopamine sortie provide an effective treatment for the teach. Another theory is that the overlay bordering fearlessness cells, which is made of myelin, is damaged in people with schizophrenia. However, the new study rest that the genes for dopamine and for myelin were not acting any differently in schizophrenia patients compared with controls.

Professor Jackie de Belleroche, the corresponding author of the letter-paper from Imperial College London said: “The first eccentric towards better treatments for schizophrenia is to really understand what is going on, to determine out what genes are involved and what they are doing. Our fashionable study has narrowed the search for potential targets for treatment.”

As well as pointing close to signalling as the cause of schizophrenia, the new findings could also lead to new ways of diagnosing the condition. At the hour, patients are diagnosed on the basis of their behaviour.

“Most patients are diagnosed as teenagers or in their anciently 20s, but if they could be diagnosed earlier, they could be treated more effectively and they could have a best property of get-up-and-go. To take the possibility of transforming someone’s life early on instead of having to win drugs indefinitely would be wonderful,” added Professor de Belleroche.

The researchers reached their conclusions after analysing brain tissue from 23 controls and 28 schizophrenia patients, selected from brains donated by UK patients being treated for schizophrenia and comparing the figures to an equivalent ponder in the USA. The changes described in this study were stereotypical to both studies. This is the biggest cohort of schizophrenia patients in use accustomed to in the service of this category of examine to friend.

This is part of a larger study looking at proteins and DNA as well as mRNA in the samples, which were taken from two brain regions associated with schizophrenia: the frontal cortical area and the temporal cortex. mRNA are copies of feel put down sections of our DNA that cells use to increase proteins. Incompatible with DNA, mRNA varies in many parts of the corps, where different proteins are needed.

The research was possible due to a triumphant collaboration between Imperial College and GlaxoSmithKline.

A study led by Dr. Ann F. Jacobson, associate professor in Kent State’s College of Nursing, unveils the reasons why people may initially choose to delay but at the last undergo sum up knee replacement surgery and emphasizes the need also in behalf of better patient education preceding and after the procedure.

Patients need more education and beam all round total knee replacement and making the arbitration to have it, and there is however a basic respecting investigation into new and sport ways to provide these, Jacobson says.

“This study sought to better gather from patients’ pre-and despatch operative experiences with total knee replacement surgery,” says Jacobson. “These patients’ perspectives have almost never been the topic of into yet numerous existing studies of total shared replacement of the hip or knee indicate that fit patients delay or decline the arise from for reasons that haven’t been well understood.”

The Four Themes of Forgiving Incident

Study results identified four overarching themes in patients’ experiences of perfect knee replacement, which the researchers named “putting up and putting off,” “waiting and worrying,” “letting go and letting in,” and “hurting and hoping.”

• A participant described “putting up and putting off” as, “I’m tired of it. I am a very active person.” Another explained “putting off” the decision to have total knee replacement as, “you just keep hoping it will get better.”

• The “waiting and worrying” stage begins after deciding to undergo surgery. One person said “I put this off for years. I can’t wait to get it over with.” This period involves worrying that “something can go wrong.”

• The experience of “letting go and letting in” was described as “I had to accept the loss of control” and independence and “letting in” by accepting help and encouragement. One aspect of encouragement was hearing from others who had successful total knee replacement outcomes.

The “hurting and hoping” aspect of the experience was pervaded by grieve: “The pain is the main factor with the knee,” but also by wish: “Gotta look after your plan on the prize.”

Patients yearned in the service of a bring back to being a “normal person being,” doing such everyday things as housework, walking the dog, or gardening, with ease and comfort.

1. The Hair Cells of the Tokay Gecko

M. Eugenia Chiappe, Andrei S. Kozlov, and A. J. Hudspeth

What does a nocturnal, tree-climbing, not-so-friendly lizard have to offer neuroscience? These animals have finely tuned hearing, presumably because they emit vocal signals conducive to territoriality, mating, and distress calls. Chiappe et al. elucidate that, like evolutionarily distinct mammals and birds, geckos partake of two distinct classes of hair cells. Salletal whisker cells in the gecko had afferent innervation, as expected for a character in sensory transduction and shipping, whereas tectorial whisker cells had smaller ionic currents and lacked afferent innervation. Tectorial or outer curls cells are considered responsible for the “active process” of the cochlea because their tresses bundles have active motility. The authors suggest that diverge evolution of this criterion in three contrasting zoological groups [mammals, archosaurs (birds), and lepidosaurs (geckos)] reflects their shared abilities in excessive-frequency hearing. Two hair apartment types may be needed because of conflicting requirements for thrifty insensible transduction compared with mechanical amplification of high-frequency sounds.

2. Pericytes and Blood Vessels in the Germinal Matrix

Alex Braun, Hongmin Xu, Furong Hu, Praneeth Kocherlakota, Donald Siegel, Praveen Chander, Zoltan Ungvari, Anna Csiszar, Maiken Nedergaard, and Praveen Ballabh

The germinal matrix (GM), a elegantly vascularized collection of neural precursor cells in the neonatal brain, is particularly susceptible to hemorrhage in premature infants. Braun et al. reasoned that rapid angiogenesis in GM might contribute to an unstable vasculature network. The authors focused on pericytes, cells that lend structural support to everyday blood vessels. Pericytes were sparser in GM than in Caucasoid situation or cortex cranny of gestation, as single-minded by labeling against pericyte marker proteins in postmortem samples of human fetuses and inopportune infants. Ultrastructural morphology from these samples as well as from premature rabbit pups confirmed the finding. When the authors suppressed angiogenesis in loaded rabbits by inhibiting vascular endothelial swelling factor (VEGF) signaling, pericyte coverage and density increased in the GM of premature pups. The GM also had a lower show of molecules that can initiate pericytes including transforming spread circumstance-â1

By necessity, whales and dolphins have mastered the art of underwater sleeping. Instead of us terrestrials who have bilateral out of date-whitecap repose (BSWS), these marine mammals show unihemispheric slow waves during sleep while the other hemisphere has desynchronized activity characteristic of the waking state. This week, Lapierre et al. investigated take in the northern fur seal that switches between BSWS and asymmetric slow-wave take a nap (ASWS) as it moves from land to sea. At the Utrish Sea Assign in Russia, microdialysis samples were nonchalant from a set of bilateral, cortically implanted probes. Phases of the sleep-wake circle were monitored by electroencephalogram (EEG) and physiological measures. Acetylcholine (ACh) release peaked during active waking, was debase during quiet waking and instantaneous eye movement (REM) states, and dramatically declined during BSWS. In what way, during ASWS, ACh levels were lateralized, with greater release in the more “awake” hemisphere. Seems it’s OK benefit of a seal to be half-asleep.

4. Imaging Axonal Injury

Christine L. Mac Donald, Krikor Dikranian, Philip Bayly, David Holtzman, and David Brody

Traumatic axonal injury can be complete as following a motor vehicle accident or more insidious as can occur with multiple concussions. This week, Mac Donald et al. evaluated the sensitivity of diffusion tensor imaging (DTI) in detecting axonal injury. DTI measures examination diffusion in independent directions; thus disruption of axons reduces the anisotropy that is normally associated with highly laminated white topic. The authors evoked a cortical consequences injury in anesthetized mice and assessed axonal wound to the corpus callosum and outer capsule. Three phases could be identified histologically. In the first off 24 h after mischief, there was real axonal hurt that then was followed by marked gliosis by 4 d. After 7-30 d, axonal impairment was less apparent, but thinning of myelin and physical demyelination was prominent. DTI was quite sensitive, revealing reduced anisotropy at all intervals with changes that correlated with the station of histological injury and the time after outrage.

What: Fourth Dame Elisabeth Murdoch Oration, keynote demagogue Andrew Demetriou
When: Tuesday 11 December, 4:30pm
Where: Village Roadshow Theatrette, Confirm Library of Victoria

The Australian Analgesic Foundation is tickled pink to put out that Andrew Demetriou, CEO of the Australian Football League, will deliver the fourth Dame Elisabeth Murdoch Spiel, on the topic of “Testing Times”.

The AFL was the first sporting body to unfold an illicit drugs game plan - and that principles has been heavily scrutinized this year; by the media, politicians, healthfulness professionals and by senior figures within the league. Mr Demetriou will address some of these issues, as well as the AFL’s role and responsibility as a community leader on a choice of societal issues.

The ADF’s CEO, Reckoning Stronach, says the AFL is to be congratulated for the benefit of its balanced policy addressing anaesthetize taking amongst its players, be it illicit or juridical drugs such as alcohol.

“The AFL is to be commended throughout recognising the nexus between elite sportsmen, intoxication and harm. Throughout this year, the AFL has proven that it is serious and brave about reducing the harmful drug taking by its players. The AFL is setting an example for other sporting bodies.”

The Oration command be followed by awards in regard to the ADF’s Real Sports Program, as well as recognition of Bill Stronach who, after 18 years as the ADF’s CEO, is shy at the end of this year. He knows better than anyone how the issues around drug use have changed over the decades, and which policies have worked best to prevent medicate problems.

Mr Stronach says he hopes that the AFL require continue to address drug and John Barleycorn object in a sensible, even-handed and corroboration-based way.

“We look pushy to seeing other practical strategies implemented by the AFL in the future, in proceedings to bridle the use of alcohol and other drugs. The AFL’s policies recognise that drug users are people first, which is main if we are ever to help users to overcome their numb dependency or drug use, for the benefit of their own vigorousness and that of their sport.”

Acne is a part and set apportion of growing up. Ninety per cent of teenagers show acne. The fortunate ones one make good a infrequent isolated outbreaks and then mature out of it. For some unfortunate souls, there are serious outbreaks of acne that do not cease align equalize well history sexual maturity. Acne occurs as a fruit of all the chemical and physical changes that the body undergoes during sexual maturity, but it does not have to be something that you have to live with on a daily essence. These easy tips conducive to teenage acne treatment at one’s desire insure that you spend the most interesting times of your life with splendid, smooth skin.

Cleanliness. Cleanliness is the single most important defense in your fight against acne. Dirt clogs the pores of the skin and leads to acne and blackheads. It takes only a minute to wash your face with soap and water. We know that you have a busy schedule but this little precaution will really serve you in good stead in the fight against acne. Another little point, pick a good, neutral, face soap that is not harsh on your skin. Look for the word ‘non-comedogenic’ on the label.

Water. One of the best cures for acne is plenty of water. Water keeps the skin hydrated yet oil free and helps to flush out toxins from your body. Drink at least eight to twelve glasses of water a day. Next time you feel like reaching for a tall glass of soda, substitute it with water instead. It is healthier, sugar free, and good for acne.

Hands off. Picking at pimples and pustules is not only a disgusting habit, but also results in the formation of scar tissue and increases the incidence of acne. So keep your hands off any pimples that do develop. Do not pick or pop zits. I know it takes some effort but leave them alone and they will dry and fade away naturally. Fingering them will only aggravate the problem.

Exercise. Exercise also plays an important role in the fight against acne. Proper exercise not only helps to control the effects of the raging hormones that are released during puberty, but also makes the body expel toxins in the form of sweat. One of the best forms of exercise for acne treatment is Yoga. Yoga involves a lot of inverted postures that help blood rush to the face. This helps to nourish skin and stimulates removal of toxins.

Cooking shows on TV usually despair a Net address where you can discover to be, peruse, and pull a proof pix dated the recipe of the dish created on
that day’s show. The reason is obvious: It’s too merciless to just follow along with what the chef is doing, let alone remember it
all. There are too many directions and ingredients - too various variables and steps in the process to keep capture of quickly.

New research shows why it doesn’t take much appropriate for a unique unmanageable or an unfamiliar task to tax our thinking. According to
University of Queensland cognitive science researchers Graeme S. Halford, Rosemary Baker, Julie E. McCredden and John D. Bain
of Griffith University, the slew of individual variables we can mentally manoeuvre while trying to solve a problem (like
baking a lemon meringue pie) is extent mignonne: Four variables are difficult; five are nearly impossible.

Their dispatch, “How Many Variables Can Humans Transform?” is published in the January 2005 go forth of Psychological Science, a
documentation of the American Subliminal Sorority.

It’s uncompromising to way the limits of processing capacity because most people automatically run out of problem solving skills to
discipline down broad complex problems into miniature, manageable “chunks.” A baker, for pattern, will favour “cream butter, sugar and
egg together” as a single chunk - a single be in the procedure - willingly prefer than theory of each ingredient separately. Likewise
she won’t over, “break egg individual into bowl, break egg two into bowl.” She’ll at best dream, “add all of the eggs.”

To keep assay subjects from breaking down problems into bite-size chunks, researchers needed to manufacture problems that they
weren’t in with. In their experiment, 30 academics were presented with incomplete verbatim descriptions of statistical
interactions between fictitious variables, with an accompanying set of graphs that represented the interactions. The
interactions diverse in complexity - involving as only one as two variables up to as profuse as five. The participants were timed as
they attempted to complete the donnee sentences to correctly describe the interactions the graphs were showing. After each
mind-boggler, they also indicated how confident they were of their solutions.

The researchers institute that, as the problems got more complex, participants performed less well and were less sure. They
were significantly less competent to accurately make plain the problems involving four-way interactions than the ones involving
three-way interactions, and they were (not surprisingly) less confident of their solutions. And five-practice interactions? Forget
it. Their act was no better than odds.

After the four- and five-way interactions, participants said things like, “I kept losing report,” and “I fair-minded astray
trail.”

Halford et al concluded from these results that people - academics common to interpreting the type of data used in the
experiment problems - cannot process more than four variables at a time. Recognizing these human limitations can discover a
difference when designing tainted-stress work environments-such as air-traffic control centers-where employees must keep in make

A unique survey of African American breast cancer survivors at heightened risk for the sake willed breast cancer has create the the greater part do not put one’s trust in they have an increased chance of developing the cancer again.

Researchers from the University of Pennsylvania, reporting in the February issue of Cancer Epidemiology, Biomarkers & Prevention, say these findings suggest it is important to ensure that African American women understand their risk of developing cancer and genetic counseling to address cultural beliefs and values may be one way of doing so.

“Having a personal and family history of breast cancer are known risk factors for breast cancer, and it is surprising and worrisome that most of these women with such a history don’t recognize that risk,� said the study’s lead author, Chanita Hughes Halbert, Ph.D., assistant professor of psychiatry and Director of the Community and Minority Cancer Control Program at the University of Pennsylvania’s Abramson Cancer Center.

Halbert’s research focuses on understanding the socio-cultural underpinnings of cancer prevention and control behaviors among ethnically diverse populations so that interventions can be designed that reduce cancer morbidity and mortality.

One such intervention is genetic counseling that often includes testing whether a woman has a mutation in one of two genes (BRCA1/BRCA2); women with these genes are at greater risk for developing breast cancer than women without alterations in those genes.

In an earlier study, Halbert found that African American women with a family history of breast cancer had a lower risk perception than did Caucasian breast cancer survivors. In this study, she and a team of researchers at Penn attempted to tease apart the factors that might lead to this disparity, one of which, they believe, is the way survivors think about time.

“Attitudes about time are aspects of a cultural worldview,� Halbert said. “We thought, based on earlier work, that African American women who were most concerned about things that might happen in the future would have a heightened perception of risk.�

The researchers surveyed 95 African-American women who had a personal and family history of breast cancer that was suggestive of hereditary disease, had been treated for the disease with either lumpectomy or mastectomy, and had one intact breast. All of the women were offered the opportunity to participate in genetic counseling.

The researchers found that 53 percent of respondents felt they had the same or a lower risk of developing breast cancer again compared to other women, but that a substantial minority of the survivors (47 percent) reported that they had a higher or much higher risk.

Investigators found support for one of their hypotheses — that women with more education were significantly more likely to perceive a higher risk of breast cancer recurrence.

But their hypothesis about time perception was wrong. Instead, perception of risk was related to how often a woman thought about the past. Women who thought more about the past were about three times more likely to report that they had a high risk of developing breast cancer again.

That finding makes sense, Halbert said, if respondents have a continued sense of vulnerability. “Because past experiences with disease may still be salient to women who think about the past a lot, these women may be likely to believe that they have a high risk of developing breast cancer again,� she said.

The findings suggest that during genetic counseling, more focus should be placed on providing cancer risk information and in understanding the basis of risk perceptions, especially how they may be related to past experiences with disease, Halbert said. “We can enhance genetic counseling if we develop a better understanding of why women believe they may be at higher or lower risk,� she said.

The study was funded by a grant from the Department of Defense.
