Radiation therapy for cervical cancer increases risk for colorectal cancer

Radiation therapy for cervical cancer increases risk for colorectal cancer

Researchers at the University of Texas Medical Branch at Galveston are the first to recommend that young women treated with radiation for cervical cancer should begin colorectal cancer screening earlier than traditionally recommended. The UTMB researchers, finding a high incidence of secondary colorectal cancers among cervical cancer survivors treated with radiation, offer new recommendations that the younger women in this group begin colorectal cancer screening about eight years after their initial cervical cancer diagnosis instead of waiting until age 50 Continue reading

More effective kidney stone treatment, from macroscopic to nanoscale

More effective kidney stone treatment, from macroscopic to nanoscale

Researchers in France have hit on a novel method to help kidney stone sufferers ensure they receive the correct and most effective treatment possible. Kidney stones represent a major medical problem in the western and developing world. If left untreated, apart from being particularly painful, they can lead to renal failure and other complications.

Fighting neuroblastomas by blocking DNA replication, repair

Fighting neuroblastomas by blocking DNA replication, repair

Neuroblastoma is one of the deadliest childhood cancers, accounting for 15 percent of pediatric cancer deaths. For patients with high-risk neuroblastomas, the five-year survival rate is 40 to 50 percent even with the most rigorous treatments available today. But those odds may improve soon, thanks to a new compound developed by City of Hope scientists Continue reading

Body mass index associated with breast cancer, regardless of body shape

Body mass index associated with breast cancer, regardless of body shape

A study of predominantly white women finds a larger waist circumference is associated with higher risk of postmenopausal breast cancer, but not beyond its contribution to BMI. Continue reading

Body mass index associated with breast cancer, regardless of body shape

A study of predominantly white women finds a larger waist circumference is associated with higher risk of postmenopausal breast cancer, but not beyond its contribution to BMI. The study, by American Cancer Society researchers, fails to confirm previous findings that body shape itself is an independent risk factor for breast cancer. Continue reading

Functional brain imaging reliably predicts which vegetative patients have potential to recover consciousness

Functional brain imaging reliably predicts which vegetative patients have potential to recover consciousness

A functional brain imaging technique known as positron emission tomography (PET) is a promising tool for determining which severely brain damaged individuals in vegetative states have the potential to recover consciousness, according to new research published in The Lancet . It is the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice Continue reading

Functional brain imaging reliably predicts which vegetative patients have potential to recover consciousness

A functional brain imaging technique known as positron emission tomography (PET) is a promising tool for determining which severely brain damaged individuals in vegetative states have the potential to recover consciousness, according to new research published in The Lancet . It is the first time that researchers have tested the diagnostic accuracy of functional brain imaging techniques in clinical practice. “Our findings suggest that PET imaging can reveal cognitive processes that aren’t visible through traditional bedside tests, and could substantially complement standard behavioural assessments to identify unresponsive or “vegetative” patients who have the potential for long-term recovery,” says study leader Professor Steven Laureys from the University of Liége in Belgium Continue reading

Antibiotics improve growth in children in developing countries

Antibiotics improve growth in children in developing countries

Antibiotics improve growth in children at risk of undernourishment in low and middle income countries, according to researchers at McGill University who have just conducted a research literature review on the subject. Their results, published in the British Medical Journal , suggest that the youngest children from the most vulnerable populations benefit most and show significant improvements toward expected growth for their age and sex, particularly for weight Continue reading

Fiber-optic microscope will help physicians detect cancer, diseases at early stages

Fiber-optic microscope will help physicians detect cancer, diseases at early stages

An engineering researcher at the University of Arkansas has developed an inexpensive, endoscopic microscope capable of producing high-resolution, sub-cellular images of tissue in real time. The fiber-optic device, which is portable, re-usable and easily packaged with conventional endoscopes, will help clinicians detect and diagnose early-stage disease, primarily cancer.

We’re over the hill at 24, study says

We’re over the hill at 24, study says

It’s a hard pill to swallow, but if you’re over 24 years of age you’ve already reached your peak in terms of your cognitive motor performance, according to a new Simon Fraser University study. SFU’s Joe Thompson, a psychology doctoral student, associate professor Mark Blair, Thompson’s thesis supervisor, and Andrew Henrey, a statistics and actuarial science doctoral student, deliver the news in a just-published PLOS ONE Journal paper Continue reading
