BACKGROUND: Hypertensive disorders of pregnancy (HDP) are a major cause maternal morbidity and mortality associated with acute cardiac events in the peripartum period, as well cardiovascular disease later life. Despite robust association between hypertension atrial fibrillation (AFib), comparatively little is known about HDP its subtypes sex-specific risk factors for AFib. METHODS: A population-based retrospective cohort study was conducted, including 771 521 nulliparous women discharged...

Many species, particularly those that flower in spring, are flowering 3–5 d earlier than they did the first half of twentieth century. This has been interpreted as a consequence rising temperatures. However, correlated with this rise temperature is an increase atmospheric CO2, which may also modify phenology. The effects elevated CO2 and on time were examined 22 Asteraceae species. Plants exposed to three treatments, ambient temperature, (700 μL L−1) ($$\mathrm{ambient}\,+1.5^{\circ...
