Study Reports Early Diagnosis Of Mental Disorders From New Computer Test
A group of doctors in Pittsburgh have developed the Computer Assessment of Mild Cognitive Impairment (CAMCI) to identify cognitive difficulties easily and reliably. In an article in the March issue of Postgraduate Medicine entitled "Computer Assessment of Mild Cognitive Impairment," the program creators detail the procedures and the benefits of the new test, which they claim is sensitive enough to notice the smallest amount of forgetfulness. By conducting a controlled study with 524 people >60 years old, they were able to demonstrate the ease and effectiveness of the testing system.

Divisions Over Future Medicare Spending Surface In House
"A week-old agreement among House Democrats to smooth out disparities in the way Medicare reimburses rural and urban health providers is in danger of crumbling, as disputes erupted Friday over what actually was agreed to," The Wall Street Journal reports. "Some lawmakers from states with high health-care costs are also pressing House Democratic leaders for changes to the deal to ensure that their doctors and hospitals don"t see too big of a bite. ò€Ĥ Lawmakers from populous areas are questioning whether the deal on geographic disparities should be altered to allow more time for Medicare changes to take effect, since there is no longer the urgency of putting those changes into effect before the public option is rolled out. Another issue is for how long a period of time after changes go into effect urban hospitals should be "held harmless," meaning they won"t see their Medicare reimbursements cut" (Vaughan, 8/2).

Lung Cancer Risk May Be Increased By Ovary Removal

Women who have premature menopause because of medical interventions are at an increased risk of developing lung cancer, according to a new study published in the International Journal of Cancer. The startling link was made by epidemiologists from the Universitçİ de Montrçİal, the Research Centre of the Centre Hospitalier de l"Universitçİ de Montrçİal and the INRS - Institut Armand-Frappier. "We found that women who experienced non-natural menopause are at almost twice the risk of developing lung cancer compared to women who experienced natural menopause," says Anita Koushik, a researcher at the Universitçİ de Montrçİal"s Department of Social and Preventive Medicine and a scientist at the Research Centre of the Centre Hospitalier de l"Universitçİ de Montrçİal. "This increased risk of lung cancer was particularly observed among women who had non-natural menopause by having had both their ovaries surgically removed." The scientists studied 422 women with lung cancer and 577 control subjects at 18 hospitals across Montreal, Quebec, Canada. They assessed socio-demographic characteristics, residential history, occupational exposures, medical and smoking history, and (among women) menstruation and pregnancy histories. "A major strength of this study was the detailed smoking information which we obtained from all study participants; this is important because of the role of smoking in lung cancer and because smokers generally have lower estrogen levels than non-smokers," says Dr. Koushik. "Although smoking is the dominant cause of lung cancer, we know other factors can play an important role in enhancing the impact of tobacco carcinogens; this research suggests that in women hormonal factors may play such a role." Women were considered menopausal if their menstrual periods had stopped naturally, surgically (by hysterectomy with bilateral surgical ovary removal) or because of radiation or chemotherapy. Women who had at least one remaining ovary and who still had their menstrual periods at the time of diagnosis/interview were classified as premenopausal. Among participants with natural menopause, the median age for attaining menopause was 50 years old; among those with non-natural menopause, it was at 43 years. "Non-natural menopause, particularly surgical menopause, may represent an increased risk with younger age at menopause given that surgery is usually done before natural menopause occurs. It"s possible that vulnerability to lung cancer is caused by early and sudden decrease in estrogen levels or potentially long-term use of hormone replacement therapy and further research is needed to explore these hypotheses," says Jack Siemiatycki a professor at the Universitçİ de Montrçİal"s Department of Social and Preventive Medicine and a scientist at the Research Centre of the Centre Hospitalier de l"Universitçİ de Montrçİal. About the Study: The article "Characteristics of menstruation and pregnancy and the risk of lung cancer in women," published in the International Journal of Cancer, was authored by Anita Koushik and Jack Siemiatycki of the Universitçİ de Montrçİal and Research Centre of the Centre Hospitalier de l"Universitçİ de Montrçİal and Marie-Elise Parent of the INRS - Institut Armand-Frappier. Partners in Research: This study was funded by the Canadian Institutes of Health Research, the Fonds de la recherche en santçİ du Quçİbec and the Guzzo-SRC Chair in Environment and Cancer.
