Heavy menstrual bleeding significantly affects quality of life.
To investigate the prevalence of women subjectively experiencing heavy menstrual bleeding in the general population and their health-related quality of life (HRQoL) compared with women experiencing normal menstrual blood loss. ⋯ Of women 40-45 years old, 32% experience heavy menstrual bleeding. These women have significantly worse HRQoL compared with women with normal menstruation patterns.

Fetal heart rate variability during pregnancy, obtained from non-invasive electrocardiogram recordings.
Non-invasive spectral analysis of fetal heart rate variability is a promising new field of fetal monitoring. To validate this method properly, we studied the relationship between gestational age and the influence of fetal rest-activity state on spectral estimates of fetal heart rate variability. ⋯ The observed increase in absolute spectral estimates in preterm fetuses was probably due to increased sympathetic and parasympathetic modulation and might be a sign of autonomic development. Further improvements in signal processing are needed before this new method of fetal monitoring can be introduced in clinical practice.
