New test for early detection of prostate cancer shows promise
In the first clinical study of a new blood protein associated with prostate cancer, researchers have found that the marker, called EPCA or early prostate cancer antigen, can successfully detect prostate cancer in its earliest stages.

Integrated chemical-dependency and mental-health treatment best for adolescents
Adolescents with alcohol- and drug-use disorders often have co-occurring mental-health disorders.

Still have to swab those tonsils, Mayo Clinic study finds
Mayo Clinic ear, nose and throat surgeons hoped to find a more user-friendly test for strep throat than swabbing the tonsils directly, but instead discovered that the swab has to touch the tonsils to accurately detect the infection.

Changes in brain receptors linked to seizures and anxiety during the menstrual cycle
A new UCLA study shows that changes in certain brain receptors can affect seizures and anxiety during the menstrual cycle--findings that could lead to novel therapies for premenstrual dysphoric disorder (PMDD, formerly known as PMS) and other central nervous system symptoms associated with the menstrual cycle.

Streptococcus pneumoniae is a bacterium that causes a number of infections, including pneumonia.

Given misleading cues, older adults are more likely to 'remember' that misinformation
Especially if you're older, get everything in writing, from estimates to receipts.

Molecular testing in patients with rare cancer predicts response to Gleevec
Patients with gastrointestinal stromal tumors (GIST) who have a particular genetic mutation are more likely to respond to Gleevec (imatinib) than those without the mutation, according to OHSU study results showcased at the 2005 annual meeting of the American Society of Clinical Oncology (ASCO).

Breast tumor's biological traits guide hormone therapy
The characteristics of an individual patient's breast cancer can help physicians choose the most effective treatment sequence with tamoxifen and the newer aromatase inhibitors, according to a study led by researchers from Dana-Farber Cancer Institute.

Mayo Clinic researchers report on effectiveness of treatments for hot flashes
Mayo Clinic researchers, working with North Central Cancer Treatment Group (NCCTG) investigators, will present new study findings about treatments to reduce hot flashes in women.

Study shows non-children's hospitals serve majority of US children
A study comparing U.S. pediatric hospitalizations showed that only one-third of a total 1.7 million hospitalizations in the year 2000 were to children's hospitals with specialized pediatric expertise.

Test predicts risk of blood clots in women receiving tamoxifen therapy for breast cancer
New research may help physicians determine which breast cancer patients have an increased risk of blood clots when taking tamoxifen.

Investigating the appropriateness of current alcohol-use disorder criteria for adolescents
The same alcohol-use disorder criteria are currently used for both adults and adolescents, despite concerns about the appropriateness of these criteria for adolescents.

Neuroimaging confirms the greater vulnerability of women's brains to alcohol

Majority of parents don't actively limit children's media time
Parents' active involvement in what their children are exposed to in the media can reduce negative effects associated with that exposure.

Study finds prostate cancer in 25% of high-risk men with 'normal' PSA levels
Men at high risk of developing prostate cancer should undergo aggressive screening for the disease.

Moderate alcohol use linked to increase in breast cancer risk
Postmenopausal women who consume even moderate amounts of alcohol may face an increased risk of breast cancer, particularly if their cancer is fueled by the hormones estrogen or progesterone, according to a data analysis by researchers at Boston's Dana-Farber Cancer Institute, Brigham and Women's Hospital, and Harvard School of Public Health.

Disabling gene defuses rheumatoid arthritis in mice
Scientists studying mice have identified a gene that allows immune cells known as neutrophils to protect themselves from the inflammatory chemicals they secrete.

Trampoline injuries on the rise
Trampoline injuries in children have nearly doubled in the past decade.

New procedures more accurate in early diagnosis of GI cancers
Researchers have developed two new tests that are more accurate than current technologies in the early diagnosis of important gastrointestinal cancers.

Bridging the digital divide by making computers for kids as common as pencils
A global education system in which a fully portable personal computer is as common as a pencil or textbook to school children even in the poorest nations is the vision of a Massachusetts Institute of Technology (MIT) professor, who will next week detail in Tokyo for the first time an accelerating international drive to mass manufacture a $100 laptop.

Popular procedures evaluated for diagnostic accuracy and treatment effectiveness
A number of new technologies are helpful in diagnosing and treating gastric disorders, while others need more testing, according to new research presented today at Digestive Disease Week® 2005 (DDW).

Mount Sinai study shows Hispanics have worse lung cancer survival rate
In a national population-based study of 16,036 lung cancer patients, Hispanics with curable stage I lung cancer had poorer lung cancer specific survival rates, as well as worse all-cause mortality, than a much larger group of white persons.
