Racial differences in cancer care still unexplained
Even though black patients and white patients with rectal cancer are equally likely to consult with an oncologist, blacks are less likely to undergo additional treatment after surgery, according to research findings posted online by the Journal of the National Cancer Institute.
The lower rates of radiation and chemotherapy partially explain why long-term survival after rectal cancer surgery is up to 20 percent lower for black patients than for white patients. Dr. Arden M. Morris, at the University of Michigan in Ann Arbor, and her colleagues hypothesized that blacks may not be referred as often to medical and radiation oncologists.
Using information from a large national database, the researchers identified 2,716 patients 66 years of age or older who had undergone surgery for stage II or III rectal cancer.
Tackle obesity like smoking: researcher
Tackling the global obesity epidemic will require governments to take similar action to that many used to curb smoking, a top researcher said on Wednesday.
This could include regulations that restrict how companies market “junk” food to children and requirements for schools to serve healthy meals, said Professor Boyd Swinburn, a public health researcher who works with the World Health Organisation.
“The brakes on the obesity epidemic need to be policy-led and governments need to take centre stage,” Swinburn, a researcher at Deakin University in Australia, told Reuters at the 2008 European Congress on Obesity.
Supplemental Breast Ultrasound Boosts Cancer Detection
Among women at high-risk of developing breast cancer, breast ultrasound combined with mammography may detect more cancers than mammography alone, according to results of a multicenter trial that included UT Southwestern Medical Center researchers.
Overall, 40 participants were diagnosed with breast cancer. Of those cases, a dozen lesions were suspicious only on ultrasound and eight were suspicious on both ultrasound and mammography.
The most recent findings, presented in the current issue of The Journal of the American Medical Association, are from the first round of screening in the American College of Radiology Imaging Network’s ACRIN-6666 trial. More than 2,800 women at high risk of developing breast cancer participated. The median age of the participants was 55 years and more than half had a personal history of breast cancer.
Girls, Young Women Can Cut Risk of Early Breast Cancer Through Regular Exercise
Mothers, here’s another reason to encourage your daughters to be physically active: Girls and young women who exercise regularly between the ages of 12 and 35 have a substantially lower risk of breast cancer before menopause compared to those who are less active, new research shows.
In the largest and most detailed analysis to date of the effects of exercise on premenopausal breast cancer, the study of nearly 65,000 women found that those who were physically active had a 23 percent lower risk of breast cancer before menopause. In particular, high levels of physical activity from ages 12 to 22 contributed most strongly to the lower breast cancer risk.
The study, by researchers at Washington University School of Medicine in St. Louis and Harvard University in Boston, will be available online May 13 in the Journal of the National Cancer Institute.
Drug Therapy for PKU Reverses Heart Damage
A pricy drug used to treat a rare but well-known genetic disorder may hold wider promise as a treatment for millions of Americans with potentially lethal enlarged hearts, due mainly to high blood pressure, a study from Johns Hopkins shows.
The common denominator in both phenylketonuria (PKU) and cardiac hypertrophy is the chemical tetrahydrobiopterin (BH4). In PKU, this enzyme coworker helps break down the molecule phenylalanine whose buildup is toxic to the brain. In the heart, BH4 helps build the chemical nitric oxide, which is needed for normal heart function and neutralizing toxic chemicals, called oxygen free radicals.
Doctors have used BH4 and diets that exclude phenylalanine for almost a decade to treat PKU, a so-called inborn error of metabolism that if left untreated causes irreversible brain damage. It affects an estimated 15,000 newborns in the United States each year.
Office initiative reduces headaches and neck and shoulder pain by more than 40 percent
Office staff who took part in an eight-month workplace initiative reported that headaches and neck and shoulder pain fell by more than 40 per cent and their use of painkillers halved, according to research published in the May issue of Cephalalgia.
They also reported that pain levels were less severe at the end of the study than at the start.
Italian researchers compared 169 staff in Turin’s registry and tax offices with 175 colleagues who hadn’t taken part in the educational and physical programme. Using daily diaries completed by both groups, they compared the baseline results for months one and two of the study with months seven and eight to see if there had been any changes. The study group started following the programme in month three.
Female sex offenders often have mental problems
Women who commit sexual offences are just as likely to have mental problems or drug addictions as other violent female criminals. This according to the largest study ever conducted of women convicted of sexual offences in Sweden.
Between 1988 and 2000, 93 women and 8,500 men were convicted of sexual offences in Sweden. Given that previous research has focused on male perpetrators, knowledge of the factors specific to female sex offenders has been scant.
A group of researchers at the Swedish medical university Karolinska Institutet have now looked into incidences of mental illness and drug abuse in these 93 convicted women, and compared them with over 20,000 randomly selected women in the normal population and with the 13,000-plus women who were convicted of non-sexual crimes over the same period.
