Estrogens reduce and withdrawal of estrogens increase risk of microsatellite instability-positive colon cancer.
There are sex differences in the occurrence of microsatellite instability (MSI) in colon tumors. Taken together with the epidemiological evidence that hormone replacement therapy (HRT) and, less consistently, parity, are inversely associated with colon cancer, it has been hypothesized that estrogens are associated with MSI. The purpose of this study was to evaluate sex-specific differences in t...
متن کاملLower glycemic load meals reduce diurnal glycemic oscillations in women with risk factors for gestational diabetes
OBJECTIVE Maternal glycemia plays a key role in fetal growth. We hypothesized that lower glycemic load (GL) meals (lower glycemic index, modestly lower carbohydrate) would substantially reduce day-long glucose variability in women at risk of gestational diabetes mellitus (GDM). RESEARCH DESIGN AND METHODS A crossover study of 17 women (mean±SD age 34.8±4 years; gestational weeks 29.3±1.3; bod...
متن کاملDo speed cameras reduce collisions?
We investigated the effects of speed cameras along a 26 mile segment in metropolitan Phoenix, Arizona. Motor vehicle collisions were retrospectively identified according to three time periods - before cameras were placed, while cameras were in place and after cameras were removed. A 14 mile segment in the same area without cameras was used for control purposes. Five cofounding variables were el...

The authors examined the relationship between the sex composition of offspring and parental survival in contemporary China and Taiwan. Because of the importance of sons for the provision of support to elderly parents in the...
متن کاملDo hospital mergers reduce costs?
Proponents of hospital consolidation claim that mergers lead to significant cost savings, but there is little systematic evidence backing these claims. For a large sample of hospital mergers between 2000 and 2010, I estimate difference-in-differences models that compare cost trends at acquired hospitals to cost trends at hospitals whose ownership did not change. I find evidence of economically ...
