Study confirms the "seed and soil" theory of metastasis

Oncologists have long puzzled over the fact that after cancer treatment, single cancer cells that are dispersed throughout the body - so-called disseminated tumor cells - are quick to grow and form secondary tumors called metastases in certain organs, while in other organs they metastasize more slowly, sometimes decades later. Such is the case with head and neck squamous cell carcinoma cells, which remain dormant when lodged in bone marrow but rapidly form tumors when they make their way into the lungs.

Patients with severe rheumatoid arthritis more likely to have heart problems

People with rheumatoid arthritis and other chronic inflammatory conditions are at higher risk of heart disease. Who is in the most danger, why and how best to prevent and detect cardiovascular complications are important questions for physicians and researchers.

Study examines incidence of adverse drug events in hospitalized children

New research from a University Hospitals Rainbow Babies & Children's Hospital study found that children ages 1 to 3 years accounted for one-fifth of all emergency department visits caused by complications from asthma, representing the highest proportion of visits among asthma patients under age 21.

International researchers identify 11 new genes linked to Alzheimer's disease

An international group of researchers has identified 11 new genes that offer important new insights into the disease pathways involved in Alzheimer's disease. The highly collaborative effort involved scanning the DNA of over 74,000 volunteers-the largest genetic analysis yet conducted in Alzheimer's research-to discover new genetic risk factors linked to late-onset Alzheimer's disease, the most common form of the disorder.

Two related genes underlie development of two rare bone tumours in nearly 100% of patients

Scientists have made a rare discovery that allows them to attribute two types of tumour almost entirely to specific mutations that lie in two related genes.

Study compares incidence, impacts of stroke between countries on global scale

Stroke, a condition traditionally associated with old age, is increasingly affecting young and middle aged people, according to a major new analysis from the Global and Regional Burden of Stroke in 1990-2010 study, published in The Lancet.

Men treated by self-referring urologists more likely to undergo unnecessary IMRT

A comprehensive review of Medicare claims for more than 45,000 patients from 2005 through 2010 found that nearly all of the 146 percent increase in intensity-modulated radiation therapy (IMRT) for prostate cancer among urologists with an ownership interest in the treatment was due to self-referral, according to new research, "Urologists' Use of Intensity-Modulated Radiation Therapy for Prostate Cancer," released today in The New England Journal of Medicine (NEJM) for its October 24, 2013 issue.

Potentially active forms of HIV hiding in infected immune T cells may be 60-fold greater, say experts

Just when some scientists were becoming more hopeful about finding a strategy to outwit HIV's ability to resist, evade and otherwise survive efforts to rid it from the body, another hurdle has emerged to foil their plans, new research from Johns Hopkins shows.

NTU launches new CryoEM lab equipped with advanced cryo transmission electron microscope

Nanyang Technological University (NTU) today launched a new electron microscopy lab led by world renowned scientist Professor Daniela Rhodes. Named the NTU Cryo-Electron Microscopy Laboratory, it is also the world's first university research facility to be equipped with an advanced cryo transmission electron microscope fitted with the latest detector/camera ten times more sensitive than a regular electron microscopy camera.

Study evaluates sexual well-being in SCT survivors using sexual function assessment tools

New research ties preparative procedures and complications associated with blood or bone marrow transplantation (stem cell transplantation, SCT) with diminished sexual health in both men and women who have undergone the lifesaving procedure. Study data, published online today in Blood, the Journal of the American Society of Hematology, confirm chronic graft-versus-host disease, a serious complication that occurs when donor cells attack the recipient's cells, as a potential source of sexual dysfunction and are the first to demonstrate an association between total body irradiation and sexual dysfunction in men.

Findings bring scientists closer to establishing regenerative therapies for humans

Cells triggering tissue regeneration that are taken from one limb and grafted onto another acquire the molecular "fingerprint," or identity, of their new location, UC Irvine developmental biologists have discovered.

Share of young people affected by digital abuse has declined, shows survey

MTV and The Associated Press-NORC Center for Public Affairs Research today released the results of a new survey exploring the pervasiveness of digital abuse among teens and young adults, how it is affecting America's youth and how they're responding to it. According to the survey, trends show that the share of young people affected by digital abuse has declined since 2011, with less than half (49 percent) of those surveyed stating that they have experienced digital abuse, compared to 56 percent in 2011.

Use of IMRT for prostate cancer doubles when self-referral's financial incentives involved

A comprehensive review of Medicare claims for more than 45,000 patients from 2005 through 2010 found that nearly all of the 146 percent increase in intensity-modulated radiation therapy for prostate cancer among urologists with an ownership interest in the treatment was due to self-referral, according to new research, "Urologists' Use of Intensity-Modulated Radiation Therapy for Prostate Cancer," released today in The New England Journal of Medicine for its October 24, 2013 issue.
