1 Rate of Stroke Rises for Pregnant Women

The rate of stroke has risen significantly for pregnant women and new mothers say researchers who, using a large national database, compared the rates of strokes from 1994-5 with those from 2006-7 in pregnant and delivering women and those who recently gave birth. The rate of stroke hospitalizations rose 47% for expectant mothers and 83% for women during the postpartum period. "Now more and more women entering pregnancy already have some type of risk factor for stroke, such as obesity, chronic hypertension, diabetes or congenital heart disease. Since pregnancy by itself is a risk factor, if you have one of these other stroke risk factors, it doubles the risk,” says lead author Dr. Elena V. Kuklina, who calls for more research.

Pursued by Parkinson's

2 REM Disorder Is Risk Factor for Parkinson's

People with REM sleep behavior disorder may be more at risk for developing Parkinson's disease, say researchers. For the third time in five years, Lancet Neurology has published work on the link between Parkinson's disease and REM disorder. Individuals with the REM disorder have nightmares in which they're being pursued or attacked, but they also act out those dreams with cries, punches, screams or kicks. In the new study, researchers used brain SPECT to discover that levels of dopamine in the brain decrease more quickly in patients with REM disorder. The three-year study compared the evolution of brain SPECT in 20 patients with the REM disorder and 20 controls. Patients with the REM disorder experienced a 20 percent drop in dopamine compared with an 8 percent drop in the controls.

Long-Lasting Protective Effect

3 Tamoxifen Reduces Breast Cancer Recurrence

The Lancet published a retrospective analysis of 20 previous studies involving 21,000 breast cancer survivors, 10,645 of whom took tamoxifen five years after diagnosis, which found that relapse at 10 years was 26 percent n the tamoxifen group compared to 40 percent who did not take the estrogen inhibitor that promotes tumor growth. The relapse rate increased for both groups 15 years later but was lower in the tamoxifen group. Death rates were similar between both groups. Older women are treated with aromatase inhibitors because tamoxifen has been shown to slightly increase in uterine cancer and blood clots in this group. One weakness is that some women did not take it for five years and researchers want to know if a longer course would further reduce the risk of relapse.
