How do bacteria clog medical devices? Very quickly.

A new study has exam­ined how bac­te­ria clog med­ical devices, and the result isn't pretty. The microbes join to cre­ate slimy rib­bons that tan­gle and trap other pass­ing bac­te­ria, cre­at­ing a full block­age in a star­tlingly short period of time.

Tumors deliberately create conditions that inhibit body's best immune response

New research in the Journal of Clinical Investigation reveals that tumours in melanoma patients deliberately create conditions that knock out the body's 'premier' immune defence and instead attract a weaker immune response unable to kill off the tumour's cancerous cells.

The study also highlights a potential antibody biomarker that could help predict prognosis and identify which patients are most likely to respond to specific treatments.

Videocast on legal issues related to field trips and field courses released on YouTube

Alexandria, VA – The American Geosciences Institute (AGI) and American Geophysical Union (AGU) have released a recording of the latest AGU/AGI Heads and Chairs webinar. This month's session focuses on legal issues related to field trips and field courses. The webinar, led by panelists David Mogk from Montana State University and Steven Whitmeyer from James Madison University, serves as a guide for reducing risk and liability for geoscience departments, and reviews tips for properly planning a safe and enjoyable field trip.

Fish migrate to safer environments

Research now reveals that fish can migrate to avoid the threat of being eaten. A new study from Lund University in Sweden shows that roach fish leave lakes and move into surrounding streams or wetlands, where they are safer from predators.

Every year, millions of animals migrate worldwide. In most cases, this is due to a shortage of food or other environmental factors. However, few research studies have focused on migration as a strategy to avoid predators. It is not easy to measure and quantify the risk of an animal being eaten.

Facebook 'Likes' are a good indicator of hospital quality

Los Angeles, CA (February 28, 2013) — While those active on social media aren't shy about expressing opinions on their Facebook pages, how much do their "Likes" really reflect the quality of an organization? American Journal of Medical Quality (a SAGE journal) recently published a study that found that Facebook "Likes" were indeed an indicator of hospital quality and patient satisfaction.

"Findings suggest that Facebook offers an additional resource, beyond surveys, to gauge the attitudes of patient populations," wrote study authors Alex Timian et.al.

The patient satisfaction chasm

Quality is a central component of any discussion around health care and one of the key dimensions and measurements of quality care is the patient experience. However, many healthcare organizations struggle to become 'patient focused' and fail to score well on patient satisfaction surveys. New research from Brigham and Women's Hospital, published in the March edition of British Medical Journal Quality and Safety, offers a potential explanation -- insufficient support from hospital management to improve the patient experience by engaging physicians and nurses in the process.

US may face inevitable nuclear power exit

Los Angeles, CA (March 01, 2013). In a 2012 report, the Obama administration announced that it was "jumpstarting" the nuclear industry. Because of the industry's long history of permitting problems, cost overruns, and construction delays, financial markets have been wary of backing new nuclear construction for decades. The supposed "nuclear renaissance" ballyhooed in the first decade of this century never materialized. And then came Fukushima, a disaster that pushed countries around the world to ask: Should nuclear power be part of the energy future?

Atheists in the humanities tear into Mother Teresa again

The altruism and generosity of Mother Teresa is disputed in a paper by humanities scholars Serge Larivée and Genevieve Chenard of University of Montreal's Department of Psychoeducation and Carole Sénéchal of the University of Ottawa's Faculty of Education.

Clogged heart arteries can foreshadow stroke

Blockages in your heart arteries could mean you're more likely to have a stroke, even if you're considered low risk, according to research in the American Heart Association journal Stroke.

"This study demonstrates that stroke risk is tightly aligned with coronary atherosclerosis, showing the closely related nature of cardiovascular and cerebrovascular disease," said Dirk M. Hermann, M.D., the study's lead investigator and professor of vascular neurology and dementia at the University Hospital Essen in Germany.

Lost in translation: HMO enrollees with poor health have hardest time communicating with doctors

In the nation's most diverse state, some of the sickest Californians often have the hardest time communicating with their doctors. So say the authors of a new study from the UCLA Center for Health Policy Research that found that residents with limited English skills who reported the poorest health and were enrolled in commercial HMO plans were more likely to have difficulty understanding their doctors, placing this already vulnerable population at even greater risk.

Study shows need for improved empathic communication between hospice teams and caregivers

LEXINGTON, Ky. (Feb. 26, 2013) — A new study authored by University of Kentucky researcher Elaine Wittenberg-Lyles shows that more empathic communication is needed between caregivers and hospice team members.

The study, published in Patient Education and Counseling, was done in collaboration with Debra Parker Oliver, professor in the University of Missouri Department of Family and Community Medicine. The team enrolled hospice family caregivers and interdisciplinary team members at two hospice agencies in the Midwestern United States.

About 15 percent of patients with Wolfram syndrome do not meet current diagnostic criteria

Researchers at IDIBELL and CIBERER Virginia Nunes and Miguel López de Heredia have collected data from 400 patients with Wolfram syndrome published worldwide in the last fifteen years to better understand the natural history of disease. The findings lead them to propose a revision of the diagnostic criteria of the disease because 15% of paediatric patients escape from diagnosis.

Round or 'shaped,' implants yield good results in breast reconstruction

Philadelphia, Pa. (February 28, 2013) –For women undergoing breast reconstruction using implants, most patient-reported outcomes are similar with two different shapes of silicone gel-filled implants, reports a study in the March issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).

Spinal cancer: Guidelines for diagnosis unsupported in patients with lower back pain

A new systematic review published in The Cochrane Library has raised doubts as to the effectiveness of "red flag" indicators at both identifying and excluding cancer in patients with lower back pain. The authors of the review concluded that most individual red flags were poor at diagnosing spinal malignancies and call for further studies focused on combinations of red flags.

Screening decisions are better informed when risk information is personalized

Patients' ability to make genuinely informed choices about undergoing disease screening increases when the risk information that they receive is related to their own personal risk, rather than average risks, according to the results of a Cochrane systematic review. The authors reviewed data from studies, largely on cancer screens, in which patients were provided with personalised risk estimates.
