Study: Flesh-eating fungal infection can follow
natural disasters

HealthDay via Medical Xpress    Share    Share on FacebookTwitterShare on LinkedinE-mail article
After a natural disaster, doctors should be on the lookout for outbreaks of a rare but deadly "flesh-eating" fungal infection, researchers at the U.S. Centers for Disease Control and Prevention reported. That's the lesson, the agency said, from 13 cases of mucormycosis skin infections that struck victims of the Joplin, Mo., tornado last year. More

Study: HPV tied to throat cancers
Reuters    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A sexually transmitted infection usually thought of in connection to cervical cancer is also tied to a five times greater risk of cancer of the vocal chords or voice box, a new report suggests. Combining the results of 55 studies from the past two decades, Chinese researchers found 28 percent of people with laryngeal cancers had cancerous tissue that tested positive for human papillomavirus. But that rate varied widely by study, from no throat cancer patients with HPV to 79 percent with the infection. More

Innovative stem cell technique for heart tissue revealed
medwireNews via The Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Researchers have found that stem cell cultures infused with growth factors could be used to repair damaged heart tissue without the threat of patient rejection. Ren-Ke Li and team say that their discovery transforms aged stem cells into cells that function like much younger ones. These may one day enable scientists to grow cardiac patches for diseased or damaged hearts from a patient's own stem cells, no matter how old they are, while avoiding the risk for rejection. More



Fungus has cancer-fighting power
Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Arthrobotrys oligospora doesn't live a charmed life; it survives on a diet of roundworm. But a discovery by a team led by Mingjun Zhang, an associate professor of biomedical engineering at the University of Tennessee, Knoxville, could give the fungus's life more purpose — as a cancer fighter. Zhang and his team have discovered that nanoparticles produced by A. oligospora hold promise for stimulating the immune system and killing tumors. More

Breast cancer 'different' in younger women
MedPage Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Women 35 years of age or younger have a biologically different form of breast cancer than women who develop the disease at an older age, researchers suggested. In women ages 36 to younger than 51, the rate of triple-negative cancer — those women with estrogen-negative, progesterone-negative and HER2-negative cancers — was about 25 percent; and in women 51 years of age or older it was about 21 percent, said Sibylle Loibl, M.D., associate professor of gynecology at the University of Frankfurt, Germany, at the annual San Antonio Breast Cancer Symposium.

Brain tumors respond to diet, radiation therapy
Medical News Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Brain cancer researchers have successfully treated mice with malignant gliomas, a type of aggressive and deadly brain tumor, with a unique combination of radiation therapy and ketogenic diet, a high fat, low carbohydrate and minimal protein regime that forces the body to use fat instead of sugar for energy. Should the approach succeed in human trials, they say the diet could quickly and easily be added to current human brain tumor treatments. More

Potential blood thinner also unmasks cancer cells
Virginia Tech via Laboratory Equipment    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Virginia Tech researchers have discovered a potential way to create a new kind of anticoagulant drug commonly called a blood thinner. Working with Rafael Davalos, an associate professor of biomedical engineering, and Pavlos Vlachos, a professor of mechanical engineering, both in the College of Engineering, the scientists created a microfluidic device that emulates flow conditions within a blood vessel to explore the therapeutic role of a naturally occurring protein called Disabled-2, which ultimately prevents blood from clotting.

Converging technologies enable faster diagnoses by pathologists, physicians
Dark Daily    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Innovative and inexpensive technologies hold the promise of instantaneous diagnosis while transforming conventional clinical laboratory tools "point-of-care pathology" may not be that far away. The convergence of medical and information technologies, the falling cost of computing, and the growing availability of miniaturization technologies make it increasingly possible for pathologists and physicians to make informed, on-the-spot diagnostic decisions about patient care. A new wave of imaging technologies — including pathology tools — is poised to transform the practice of medicine, reported a recent story in The New York Times. More

Research shows iron's importance in infection, suggests new therapies
Kansas State University via Infection Control Today    Share    Share on FacebookTwitterShare on LinkedinE-mail article
A Kansas State University research team has resolved a 40-year-old debate on the role of iron acquisition in bacterial invasion of animal tissues. The collaborative research — led by Phillip Klebba, professor and head of the department of biochemistry — clarifies how microorganisms colonize animal hosts and how scientists may block them from doing so. The findings suggest new approaches against bacterial disease and new strategies for antibiotic development. More



Novel breast screening technology increases diagnostic accuracy
Oncology Nurse Advisor    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Adding three-dimensional breast imaging — tomosynthesis — to standard digital mammography significantly increases the diagnostic accuracy of radiologists while reducing the rate of false positive recalls. Screening mammography reduces cancer mortality in women aged 40 to 74 years, according to the National Cancer Institute. More

The ovarian cancer quandary: Should women be screened?
WLS-TV    Share    Share on FacebookTwitterShare on LinkedinE-mail article
VideoBrief Study after study shows the tests commonly recommended to screen healthy women don't always work and could even be a hazard. The screenings, which involve a blood test and an ultrasound, tend to give many false positive results. So women can end up having operations to look for a cancer that is many times not there. More

In node-positive breast cancer, sentinel biopsy could avert ALND
Medscape Medical News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Some women with node-positive breast cancer who receive neoadjuvant chemotherapy might not need to automatically undergo axillary lymph node dissection, according to a new study. Instead, it might be possible for some to undergo a less invasive sentinel lymph node biopsy, according to the results of a phase 2 American College of Surgeons Oncology Group study presented at the 35th Annual San Antonio Breast Cancer Symposium.

Study: Nutrients in fruits, vegetables may help prevent breast cancer
HealthDay News    Share    Share on FacebookTwitterShare on LinkedinE-mail article
Women with higher levels of micronutrients found in many fruits and vegetables may be less likely to develop breast cancer, a new study finds. Previous research has shown that the nutrients, called carotenoids, can inhibit tumor growth and reduce the spread of breast cancers. In the new study, researchers analyzed data from thousands of women who took part in eight previous studies on carotenoid levels and breast cancer. More
