(Press-News.org) (PHILADELPHIA) – Cancer and stress go hand-in-hand, and high stress levels can lead to poorer health outcomes in cancer patients. The Jefferson-Myrna Brind Center of Integrative Medicine combined creative art therapy with a Mindfulness-based Stress Reduction (MBSR) program for women with breast cancer and showed changes in brain activity associated with lower stress and anxiety after the eight-week program. Their new study appears in the December issue of the journal Stress and Health.
Daniel Monti, MD, director of the Jefferson-Myrna Brind Center of Integrative Medicine and lead author on the study, and colleagues have previously published on the success of Mindfulness-based Art Therapy (MBAT) at helping cancer patients lower stress levels and improve quality of life.
"Our goal was to observe possible mechanisms for the observed psychosocial effects of MBAT by evaluating the cerebral blood flow (CBF) changes associated with an MBAT intervention in comparison with a control of equal time and attention," says Monti. "This type of expressive art and meditation program has never before been studied for physiological impact and the correlation of that impact to improvements in stress and anxiety."
Eighteen patients were randomly assigned to the MBAT program or an education program control group. All had received the diagnosis of breast cancer between six months and three years prior to enrollment and were not in active treatment. The MBAT group consisted of the MBSR curriculum (awareness of breathing, awareness of emotion, mindful yoga, walking, eating and listening), paired with expressive art tasks to provide opportunities for self-expression, facilitate coping strategies, improve self-regulation, and provide a way for participants to express emotional information in a personally meaningful manner.
Patient response to the MBAT program was measured using a 90-item symptom checklist, completed by each patient before and after the eight-week program. In addition, functional magnetic resonance imaging (fMRI) was used pre and post-program to evaluate cerebral blood flow, corresponding to changes in the brain's activity. Scans were performed at rest, during a "neutral task" (control), meditation task, stressor task and at rest again—designed to evaluate the general as well as specific effects and provide a thorough analysis of the CBF changes between the pre and post-program scans.
Participants in the MBAT group demonstrated significant effects on cerebral blood flow compared with the control group. The MBAT group showed increases in the emotional centers of the brain including the left insula which helps us to perceive our emotions, the amygdala which helps us experience stress, the hippocampus that regulates stress responses, and the caudate nucleus that is part of our brain's reward system. These increases correlated significantly with a lowering of stress and anxiety, as also reflected in the results of the pre and post-program anxiety scores among the MBAT intervention group.
The observed psychological and neuropsychological changes are consistent with current literature that states that MBSR interventions have shown to reduce anxiety, depression and psychological distress in a variety of populations. These have been associated with improved immune function, quality of life and coping effectiveness in women with breast cancer.
Given the improvements in anxiety levels and observed changes in CBF in the MBAT participants, these findings suggest that the MBAT program helps mediate emotional responses in women with breast cancer. "With the sample size enlarged, perhaps we can extrapolate these results to other disease populations and gain a fuller understanding of the physiological mechanisms by which mindfulness practices confer psychological benefits," says Monti.

As cigarette taxes go up, heavy smoking goes down
2012-11-30
Audio available at: https://news.wustl.edu/news/Pages/24616.aspx
When cigarette taxes rise, hard-core smokers are more likely than lighter smokers to cut back, according to new research from Washington University School of Medicine in St. Louis.
"Most clinicians and researchers thought these very heavy smokers would be the most resistant to price increases," says first author Patricia A. Cavazos-Rehg, PhD. "Many believed this group was destined to continue smoking heavily forever, but our study points out that, in fact, change can occur. And that's very good news."

Clinical trial delivers good results in leukemia patients
2012-11-30
SALT LAKE CITY—Huntsman Cancer Institute (HCI) researchers Michael Deininger, M.D., Ph.D., and Thomas O'Hare, Ph.D., were part of a team that found a potent oral drug, ponatinib, effective in patients who have developed resistance to standard treatments for chronic myeloid leukemia (CML) and Philadelphia chromosome positive acute lymphoblastic lymphoma (Ph+ ALL). The New England Journal of Medicine released results of the trial today.
In the phase I clinical trial conducted at five cancer centers nationwide, ponatinib was highly active in patients with CML and Ph+ ALL ...
Prenatal intervention reduces learning deficit in mice
2012-11-30
Mice with a condition that serves as a laboratory model for Down syndrome perform better on memory and learning tasks as adults if they were treated before birth with neuroprotective peptides, according to researchers at the National Institutes of Health.
Down syndrome results when an individual receives an extra copy of chromosome 21. According to the Centers for Disease Control and Prevention, Down syndrome occurs in 1 of every 691 births. Features of Down syndrome include delays in mental and physical development and poor muscle tone. These features may vary greatly, ...
New radio telescope could save world billions

A small pocket of Western Australia's remote outback is set to become the eye on the sky and could potentially save the world billions of dollars. The Murchison Widefield Array (MWA) radio telescope, unveiled today, Friday 30 November, will give the world a dramatically improved view of the Sun and provide early warning to prevent damage to communication satellites, electric power grids and GPS navigation systems.
The $51 million low-frequency radio telescope will be able to detect and monitor massive solar storms, such as the one that cut power to six million people ...
Intermountain Healthcare Cancer research provides possible road map for improving healthcare
2012-11-30
SALT LAKE CITY – Given the right equipment, training and skill, an individual surgeon can expect to provide the best possible care on a consistent basis. But how do you get an entire system of surgeons — each with his or her own ideas, backgrounds, and routines — to provide that same level of care?
A series of studies directed by Intermountain Healthcare's Oncology Clinical Program shows that it's possible to improve care across the board if you tackle the problem in a standardized way, relying on the best evidence available.

Grey-mouse lemurs serve as model for the early primates from which humans evolved
2012-11-30
New research shows first evidence of paternal voice recognition in solitary foraging species, provides insight into early primates from which humans evolved
Think of the last time you screamed. Chances are you attracted someone's attention. What about the last time someone flirted with you? You were likely more selective in your response.
New research findings from Arizona State University and the University of Veterinary Medicine Hannover in Germany demonstrate that a less social species – the grey-mouse lemur - pays attention to alarm calls regardless of whom they ...
Even brown dwarfs may grow rocky planets
2012-11-30
Rocky planets are thought to form through the random collision and sticking together of what are initially microscopic particles in the disc of material around a star. These tiny grains, known as cosmic dust, are similar to very fine soot or sand. However, in the outer regions around a brown dwarf -- a star-like object, but one too small to shine brightly like a star -- astronomers expected that grains could not grow because the discs were too sparse, and particles would be moving too fast to stick together after colliding. Also, prevailing theories say that any grains ...

When eating for 2 becomes a weighty issue
2012-11-30
Two-thirds of Australian mums-to-be are in the dark when it comes to how much weight they should gain during pregnancy.
Susie de Jersey from Queensland University of Technology's (QUT) Institute of Health and Biomedical Innovation (IHBI) and senior dietician at the Royal Brisbane and Women's Hospital said a third of women surveyed gained too much weight during pregnancy. Another third struggled to gain enough weight with some mothers recording a lower weight just before giving birth than they did before falling pregnant.
"The majority of the women in the study knew ...
The colour of love: Zebrafish perform colorful courtship displays
2012-11-30
Elaborate secondary sexual displays are often overlooked because many species attract mates through sensory modalities imperceptible to humans, including ultraviolet light, ultrasound, electrical signals, or pheromones. Also, sexual coloration may only be expressed briefly during courtship (ephemeral courtship dichromatisms) to avoid attracting predators. Zebrafish (Danio rerio) are a widely studied model organism, though there have been few studies on their mating behaviour. Like many schooling fish, zebrafish do not appear sexually dichromatic to humans; there are no ...
