Isotopic variance among plant lipid homologues correlates with biodiversity patterns of their source communities.

Plant diversity is important to human welfare worldwide, and this importance is exemplified in subtropical and tropical [(sub)tropical] African savannahs where regional biodiversity enhances the sustaining provision of basic ecosystem services available to millions of residents. Yet, there is a critical lack of knowledge about how savannahs respond to climate change. Here, we report the relationships between savannah vegetation structure, species richness, and bioclimatic variables as recorded by plant biochemical fossils, called biomarkers.

Improvement in Outcomes of Major Obstetric Hemorrhage Through Systematic Change.

Objective: To report the outcomes over 14 years of sustained systematic institutional focus on the care of women with major obstetric hemorrhage, defined as estimated blood loss greater than 1,500 mL.

Methods: A retrospective cohort study of women with major obstetric hemorrhage at our hospital from 2000 to 2014 compares baseline conditions (age, multiparity, prior cesarean delivery, morbidly adherent placenta), morbidity (lowest mean temperature, lowest mean pH, coagulopathy, hysterectomy), and mortality among three time periods (period 1=January 2000 to December 2001, period 2=January 2002 to August 2005, period 3=September 2005 to December 2014). We also describe the systematic changes that helped to sustain our improved outcomes.

Thyroid storm-induced multi-organ failure in the setting of gestational trophoblastic disease.

Background: Thyroid storm is a potentially life-threatening complication of gestational trophoblastic disease (GTD), with varying clinical severity. It should be considered in patients with GTD, abnormal vital signs, and clinical signs of hyperthyroidism.

Case Report: A 45-year-old non-English-speaking patient presented to a New York City hospital in November 2011 with an aborting molar pregnancy and severe hemorrhage.

The Effects of Preeclampsia on Perinatal Risks and Infant Temperaments Among Mothers With Antenatal Depression.

Importance: Preeclampsia and depression are two most prevalent disorders known to affect pregnant women and unborn infant. However, few studies have prospectively examined the adverse influence of the in-utero exposures to the two disorders on the optimal development in their offspring, including mortality, adverse birth outcomes, and infant temperament styles.

Objectives: (1) To examine whether exposures to preeclampsia and antenatal depression were associated with developmental indices of offspring at birth and temperament at 3 months; and (2) To evaluate how preeclampsia and antenatal depression associated with offspring temperamental style.
