Prostate Cancer And The Role Of Radical Prostatectomy
Date: Feb-18-2013Even in the presence of screening, there is benefit to radical prostatectomy (RP) in prostate cancer patients, however, the benefit is limited to a subgroup of patients and can take years to become evident according to a study published in the Journal of the National Cancer Institute. The Scandinavian Prostate Cancer Group Study Number 4 (SPCG-4) trial identified that RP lowered prostate cancer deaths with a statistically significant absolute mortality difference (AMD) between RP and watchful waiting (WW) of 6.1%...
State Medicaid Programs Offering Coverage For Birth Doulas Could Capture Cost Savings Associated With Reduced Cesarean Rates
Date: Feb-18-2013New research from the University of Minnesota's School of Public Health has found lower cesarean birth rates among Medicaid beneficiaries with access to support from a birth doula than among Medicaid patients nationally. A doula is not a medical provider, but is a trained, experienced professional person who can provide information, physical assistance and support to a woman during childbirth. The research indicates that policy changes to provide Medicaid coverage for birth doulas may actually decrease costs due to lower rates of cesarean births among Medicaid patients with doula support...
Streptococcus pneumonia Shields Foreign DNA Derived From Other Bacteria To Promote Genetic Diversity And Vaccine Evasion
Date: Feb-18-2013A new report demonstrates that the human pathogen Streptococcus (S.) pneumoniae (one of the known causes of bacterial pneumonia) possesses an unusual enzyme that protects foreign DNA taken up during transformation, allowing exchange of pathogenicity islands donated from other pathogenic bacteria...
Discovery Of RNA Element Missing From Viral Vectors In HIV May Solve Efficiency Problems For Gene Therapy
Date: Feb-18-2013A research team from Case Western Reserve University School of Medicine has discovered an approach that could make gene therapy dramatically more effective for patients. Led by professor Eric Arts, PhD, the scientists discovered that the process of gene therapy is missing essential elements thereby reducing the effectiveness of this treatment. Re-introducing this element into their model system suggests that improvements for gene therapy areon the horizon...
Potential Cure For Chagas Disease
Date: Feb-18-2013Chagas disease, a deadly tropical infection caused by the protozoan parasite Trypanosoma cruzi and transmitted by biting insects called "kissing bugs," has begun to spread around the world, including the U.S. Yet current treatment is toxic and limited to the acute stage. In The Journal of Infectious Diseases (JID), Galina Lepesheva, Ph.D., and her colleagues at Vanderbilt University and Meharry Medical College report curing both the acute and chronic forms of the infection in mice with a small molecule, VNI. VNI specifically inhibits a T...
Darkness Therapy Helps To Restore Vision
Date: Feb-18-2013Restoring vision might sometimes be as simple as turning out the lights. That's according to a study reported in Current Biology, a Cell Press publication, in which researchers examined kittens with a visual impairment known as amblyopia before and after they spent 10 days in complete darkness. Researchers Kevin Duffy and Donald Mitchell of Dalhousie University in Canada believe that exposure to darkness causes some parts of the visual system to revert to an early stage in development, when there is greater flexibility...
Clinical Screening Program Developed For No.1 Genetic Cause Of Colon Cancer
Date: Feb-18-2013Cleveland Clinic researchers have found that colorectal cancer outcomes could be improved with regular genetic screening for Lynch syndrome, the most common hereditary, adult-onset cause of colorectal cancer, as published in the online version of the Journal of Clinical Oncology. Lynch syndrome is the most common genetic cause of colon cancer in adults...
IVF Does Not Appear To Increase Cancer Risk, Study
Date: Feb-18-2013A study on Israeli women receiving fertility treatments found that IVF (in vitro fertilization) does not appear to raise the risk of breast and other female cancers, says a new report published in Fertility & Sterility. Lead author Louise Brinton, from the National Cancer Institute, Rockville, Maryland, and team wrote that none of the gynecological cancers were significantly elevated after IVF treatment...
Effective Treatment For Women Suffering From Extremely Heavy Periods
Date: Feb-18-2013New research from the Los Angeles Biomedical Research Institute (LA BioMed) found a progestogen-only treatment halted bleeding in women suffering from extremely heavy periods, according to the study published online by the American Journal of Obstetrics and Gynecology. "Excessive uterine bleeding is a common problem we see in gynecological practices and emergency rooms. It can interfere with women's daily activities and put them at risk for anemia and other more serious health consequences caused by blood loss," said Anita L...
Bevacizumab And Dasatinib Combination Shows Promise In Fighting Glioblastoma
Date: Feb-18-2013The drug bevacizumab, also known by the trade name Avastin, shrinks tumors briefly in patients with an aggressive brain cancer known as glioblastoma multiforme, but then they often grow again and spread throughout the brain for reasons no one previously has understood. Now, Mayo Clinic researchers have found out why this happens. They have also discovered that pairing Avastin with another cancer drug, dasatinib, can stop that lethal spread. Dasatinib is approved for use in several blood cancers. The findings, based on an animal study, are detailed in the online issue of PLOS ONE...
