Researchers from North Carolina State University have for the first time successfully coated polymer implants with a bioactive film. The discovery should improve the success rate of such implants – which are often used in spinal surgeries.

The polymer used in these implants, called PEEK, does not bond well with bone or other tissues in the body. This can result in the implant rubbing against surrounding tissues, which can lead to medical complications and the need for additional surgeries.

Heart and cerebro-vascular disorders represent the two leading causes of death throughout the world. They are sometimes combined in a single patient and their combination represents both a considerable risk to the patient and a therapeutic challenge.

A study has gained new insight into domestic dogs' fear responses to noises. The behavioral response by dogs to noises can be extreme in nature, distressing for owners and a welfare issue for dogs.

The research by academics from the School of Veterinary Sciences at the University of Bristol, and funded by the RSPCA, is published in Applied Animal Behaviour Science. The study provides an important insight into dogs' fear of noises, and could improve our understanding of behavioral signs of fear or anxiety.

Watching a loved one die tests some family members' relationships with God or the higher being of one's faith. And the spiritual anger and resentment grow with the level of pain and suffering their family member endures, according to researchers at Case Western Reserve University.

Psychologist Julie Exline and palliative care advanced practice nurse Maryjo Prince-Paul surveyed 147 family members with a hospice patient under home care.

OAK BROOK, Ill. – Coronary computed tomography angiography (CCTA) is an effective tool for determining the risk of heart attacks and other adverse cardiac events in patients with suspected coronary artery disease but no treatable risk factors, such as high cholesterol or high blood pressure, according to a new study published online in the journal Radiology.

Researchers have determined that fibromyalgia prevalence is 2.1% of the general population in Germany. Results appearing in Arthritis Care & Research, a journal published by Wiley on behalf of the American College of Rheumatology (ACR), suggest that fibromyalgia is a spectrum disorder rather than a categorical illness. Additionally, a number of fibromyalgia cases in the general population satisfy proposed criteria for physical symptom disorder—the presence of one or more physical symptoms that impair function, which cannot be explained by another clinical or psychiatric illness.

Women appear to have a higher risk of implant failure than men following total hip replacement after considering patient-, surgery-, surgeon-, volume- and implant-specific risk factors, according to a report published Online First by JAMA Internal Medicine, a JAMA Network publication.

ST. LOUIS – New research at Saint Louis University shows physicians do not talk to patients about the psychosocial impact and long-term risks of implanting cardioverter defibrillators (ICDs) to treat irregular heart rhythms, leaving them misinformed about how the device may affect quality of life.

The article, titled 'Patient Perceptions, Physician Communication and the Implantable Cardioverter-Defibrillator,' was published online in JAMA Internal Medicine (formerly Archives of Internal Medicine) on February 18.

Because of increasing efficiency, water demand in the United States over the next 50 years would stay within 3 percent of current demand, even with an expected 50 percent increase in population. Butdespite increases in efficiency, advocates say water demand in the United States is likely to increase substantially in the future if the climate continues to warm.

Brown et al. project future water use to 2090 based on past trends from U.S. Geological Survey water use data from 1960 to 2005 and trends in efficiency.

With American families contributing a growing proportion of their personal income to health care, researchers find patients are consequently experiencing a range of social, medical, financial and sometimes legal disruptions resulting from high out-of-pocket expenses.

A skilful negotiator can save a lot of money when shopping in his favourite store. This was found out by researchers at the Ruhr-Universität Bochum (RUB) in a large-scale study. An extra five percent discount is, on average, no problem - as long as you know how to use your customer loyalty as a trump.

The credo turned on its head

Children and adolescents who watch a lot of television are more likely to manifest antisocial and criminal behaviour when they become adults, according to a new University of Otago, New Zealand, study published online in the US journal Pediatrics.

Clinicians with higher levels of implicit ethnic or racial bias—bias that may not be consciously acknowledged but operates in more subtle ways—are rated less favorably by their black patients than are clinicians with lower levels of implicit bias.

Surveys of nearly 3,000 patients, randomly selected from patient panels of 134 clinicians who had previously completed tests of implicit ethnic or racial bias, found black patients rated clinicians who had greater implicit bias against blacks lower in patient-centered care than they did clinicians with little or no such implicit bias.

In the lab, rats with severe spinal cord injury are learning to walk—and run—again. Last June in the journalScience, Grégoire Courtine, of the École Polytechnique Fédérale de Lausanne (EPFL), reported that rats in hislab are not only voluntarily initiating a walking gait, but they were sprinting, climbing up stairs, and avoidingobstacles after a couple of weeks of neurorehabilitation with a combination of a robotic harness and electricalchemicalstimulation.

It has been more than 50 years since Rachel Carson published her groundbreaking book "Silent Spring". Derided by scientists at the time, she is now regarded as a hero by environmental progressives and a villain by many others, but Carson certainly changed how the public views environmentalism.
