New Lower Level for Normal Intrauterine Pregnancy

| Pregnancy And Newborn by Petr Kratochvil |
When evaluating the patient who presents with increasing levels of HCG, clinical decisions are facilitated by the well-defined curve of expected hCG rise.
This curve, first described by Kadar et al, recently has been redefined.
A 53% increase in HCG concentration in 2 days, rather than a 66% increase, is now considered the lower limit of normal and defines a viable intrauterine pregnancy (K.T. Barnhart et al, in press).
A slower rate of increase from this expectation suggests a nonviable pregnancy and prompts intervention to distinguish an ectopic pregnancy from miscarriage

TODAY'S BOOK SUGGESTION:
Ready: Why Women Are Embracing The New Later Motherhood
by Elizabeth Gregory
-- Over the past three decades, skyrocketing numbers of women have chosen to start their families in their late thirties and early forties.
In 2005, ten times as many women had their first child between the ages of 35 and 39 as in 1975, and thirteen times as many had their first between 40 and 44.
Women now have the option to define for themselves when they're ready for family, rather than sticking to a schedule set by social convention.
As a society, however, we have yet to come to terms with the phenomenon of later motherhood, and women who decide it makes sense for them to delay pregnancy often find themselves confronted with alarmist warnings about the dangers of waiting too long.
In Ready, Elizabeth Gregory tracks the burgeoning trend of new later motherhood and demonstrates that for many women today, waiting for family works best.
She provides compelling evidence of the benefits of having children later -- by birth or by adoption.
