Clustering of > 145,000 symptom logs reveals distinct pre, peri, and menopausal phenotypes.

The transition to menopause is associated with disappearance of menstrual cycle symptoms and emergence of vasomotor symptoms. Although menopausal women report a variety of additional symptoms, it remains unclear which emerge prior to menopause, which occur in predictable clusters, how clusters change across the menopausal transition, or if distinct phenotypes are present within each life stage. We present an analysis of symptoms in premenopausal to menopausal women using the MenoLife app, which includes 4789 individuals (23% premenopausal, 29% perimenopausal, 48% menopausal) and 147,501 symptom logs (19% premenopausal, 39% perimenopausal, 42% menopausal).

Deep learning model using continuous skin temperature data predicts labor onset.

Background: Changes in body temperature anticipate labor onset in numerous mammals, yet this concept has not been explored in humans. We investigated if continuous body temperature exhibits similar changes in women and whether these changes may be linked to hormonal status. Finally, we developed a deep learning model using temperature patterning to provide a daily forecast of time to labor onset.

Deep Learning Model Using Continuous Skin Temperature Data Predicts Labor Onset.

Background: Changes in body temperature anticipate labor onset in numerous mammals, yet this concept has not been explored in humans.

Methods: We evaluated patterns in continuous skin temperature data in 91 pregnant women using a wearable smart ring. Additionally, we collected daily steroid hormone samples leading up to labor in a subset of 28 pregnancies and analyzed relationships among hormones and body temperature trajectory.

Epicardial placement of human placental membrane protects from heart injury in a swine model of myocardial infarction.

Cardiac ischemic reperfusion injury (IRI) is paradoxically instigated by reestablishing blood-flow to ischemic myocardium typically from a myocardial infarction (MI). Although revascularization following MI remains the standard of care, effective strategies remain limited to prevent or attenuate IRI. We hypothesized that epicardial placement of human placental amnion/chorion (HPAC) grafts will protect against IRI.
