The energy of harmonic sections of flat bundles of nonpositively curved (NPC) length spaces over a Riemann surface S is a function Eρ on Teichmüller space TS which is a qualitative invariant of the holonomy representation ρ of π1(S). Adapting ideas of Sacks-Uhlenbeck, Schoen-Yau and Tromba, we show that the energy function Eρ is proper for any convex cocompact representation of the fundamental ...

The purpose of this study was to analyze the cardiovascular effects induced by mental stress evoked by different stressors in patients with recent uncomplicated myocardial infarction. Twenty four males, aged 52 +/- 10 years, were studied 45 +/- 22 days after uncomplicated myocardial infarction in the absence of specific cardiovascular drugs. During electrocardiographic and hemodynamic monitorin...

Valvular heart disease is the common cardiac manifestation of systemic lupus erythematosus (SLE) with a tendency for mitral valve regurgitation. In this study we report a case of mitral valve replacement for mitral stenosis caused by Libman-Sacks endocarditis in the setting of SLE. In addition, we provide a systematic review of the literature on mitral valve surgery in the presence of Libman-Sa...

Health care providers' opinions can influence how parents place their infant to sleep. Neonatal nurses can improve how they teach and model safe infant sleep practices to parents. To increase neonatal nurses' knowledge, a sudden infant death syndrome (SIDS) prevention program was implemented. Program components included a computerized teaching tool, a crib card, sleep sacks, and discharge instr...
