3-D printing technology from CT images may be used effectively for neurosurgical planning

3D models, produced by combining a patient's CT scans and 3D printing technology are proving useful in neurosurgical planning.

3D printing technology is a fast and affordable way to build 3D models for neurosurgical planning. Radiologists are able to transform ultra high-resolution CT patient images into 3D solid models using a 3D color printer commonly used in architecture, engineering and construction.

Measles outbreak underscores need for continued vigilance in health care settings

[EMBARGOED FOR APRIL 29, 2011] The U.S. measles vaccination program has been successful in eliminating endemic measles in the United States; yet this success has provided challenges that require ongoing vigilance for the rapid identification and response to measles cases in health care settings. In 2008, the largest reported health care-associated measles outbreak in the United States since 1989 occurred in Tucson, Arizona, costing approximately $800,000 in response and containment efforts.

Frequently hospitalized patients may benefit from new medical specialty focused on their needs

Declining rates of hospitalization have discouraged primary care doctors from seeing their patients in the hospital and encouraged the growing use of "hospitalists," a new physician specialty focused on the care of hospitalized patients. Further developments in the field mean that frequently hospitalized patients also may need a specialist focused on their care, according to an expert on hospital care at the University of Chicago.

Concern over 'excessive' doses of thyroid drugs for older patients

Many older adults may be taking "excessive" doses of drugs for thyroid problems which can lead to an increased risk of fractures, finds a study published on bmj.com today.

The study raises concern that treatment targets may need to be modified in the elderly and that regular dose monitoring remains essential even into older age.

Levothyroxine is a synthetic form of thyroxine (thyroid hormone) and is widely used to treat an underactive thyroid gland (hypothyroidism).

1 drug, many targets: Is this the future?

Potential molecular targets of the anti-HIV drug nelfinavir have been identified, and may explain why the drug is also effective as a cancer therapy. Findings will be published in the open-access journal PLoS Computational Biology on 28th April 2011.

Green light for flu vaccine in transplant recipients

Getting vaccinated against the flu lowers kidney transplant recipients' risk of organ loss and death, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The results suggest that concerns about the safety of the influenza vaccine in transplant recipients are unwarranted.

Reducing risk of renal failure in obese patients

The angiotensin-converting enzyme (ACE) inhibitor drug, ramipril, is particularly effective in lowering the risk of end-stage renal disease (ESRD) in obese patients, according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

"Obese patients with kidney disease progress more quickly towards renal failure compared to non-obese patients, and ramipril virtually abolishes this excess risk," comments Carmine Zoccali, MD (CNR-IBIM and Ospedali Riuniti di Reggio Calabria, Italy).

Finding molecular targets of an HIV drug used in cancer therapy

Researchers at the University of California, San Diego and Hunter College of the City University of New York (CUNY) have identified potential human molecular targets of the anti-HIV drug Nelfinavir, which may explain why the drug is also effective as a cancer therapy. Their study will be published in the online edition of PLoS Computational Biology on April 28.

Iowa State chemist designs new polymer structures for use as 'plastic electronics'

AMES, Iowa – Iowa State University's Malika Jeffries-EL says she's studying doing structure-property studies so she can teach old polymers new tricks.

Those tricks improve the properties of certain organic polymers that mimic the properties of traditional inorganic semiconductors and could make the polymers very useful in organic solar cells, light-emitting diodes and thin-film transistors.

Study: Cotton swabs prove problematic for ear health

DETROIT – A study by Henry Ford Hospital shows a direct association between cotton swab use and ruptured eardrum.

The study also shows that in most cases the rupture heals on its own and surgery is only necessary for the most severe cases.

Louisiana Tech researcher presents on eco-friendly nanotechnology at national conference

RUSTON, La. – Dr. Yuri Lvov, professor of chemistry and T.C. Pipes endowed chair in micro and nanosystems at Louisiana Tech University, recently led a symposium at the 241st Conference of the American Chemical Society (ACS), discussing his application of a more eco-friendly and cost-effective nano-material that can be used to significantly improve the properties of plastics, paints and other synthetic composites.

Stress and depression are associated with shorter survival in head and neck cancer patients

WASHINGTON, DC (April 28, 2011)––Studies have shown that stress can affect the immune system and weaken the body's defense against infection and disease. In cancer patients this stress can also affect a tumor's ability to grow and spread. However, the biological mechanisms that underlie such associations are not well understood.

Antibiotic-resistant bacteria have evolved a unique chemical mechanism, new discovery reveals

For the first time, scientists have been able to paint a detailed chemical picture of how a particular strain of bacteria has evolved to become resistant to antibiotics. The research is a key step toward designing compounds to prevent infections by recently evolved, drug-resistant "superbugs" that often are found in hospitals, as well as in the general population.

As the worm turns, its secrets are revealed

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, have developed a new method for discerning the functions of previously uncharacterized genes and placing them in interactive, functional networks that reveal how gene products interact to bring about cellular events.

Fish livers contain beneficial fatty acids

The fishing industry usually discards fish livers, but a team of researchers from the University of Almeria (Spain) has confirmed that they are a good source of polyunsaturated fatty acids, which are beneficial to health. Anchovies are one of the fish whose livers contain the highest levels of these substances.
