Impact of Cryptosporidium spp. interaction with co-occurring microorganisms on moderate-to-severe diarrhea in the developing world

Diarrheal illness is responsible for over a quarter of all deaths in children under 5 years of age in sub-Saharan Africa and South Asia. Recent findings have identified the parasite Cryptosporidium as a contributor to enteric disease. We examined 9,348 cases and 13,128 controls from the Global Enteric Multicenter Study to assess whether Cryptosporidium interacted with co-occurring pathogens based on adjusted odds of moderate-to-severe diarrhea (MSD). Cryptosporidium was found to interact negatively with Shigella spp., with multiplicative interaction score of 0.16 (95% CI: 0.07 to 0.37, p-value=0.000), and an additive interaction score of -9.81 (95% CI: -13.61 to -6.01, p-value=0.000). Cryptosporidium also interacted negatively with Aeromonas spp., Adenovirus, Norovirus, and Astrovirus with marginal significance. Odds of MSD for Cryptosporidium co-infection with Shigella spp., Aeromonas spp., Adenovirus, Norovirus, or Astrovirus are lower than odds of MSD with either organism alone. This may reduce the efficacy of intervention strategies targeted at Cryptosporidium.

Contrasts: Quartets and Art Songs of the Nineteenth Century

The nineteenth-century Romantic era saw the development and expansion of many vocal and instrumental forms that had originated in the Classical era. In particular, the German lied and French mélodie matured as art forms, and they found a kind of equilibrium between piano and vocal lines. Similarly, the nineteenth-century piano quartet came into its own as a form of true chamber music in which all instruments participated equally in the texture. Composers such as Robert Schumann, Johannes Brahms, and Gabriel Fauré offer particularly successful examples of both art song and piano quartets that represent these genres at their highest level of artistic complexity. Their works have become the cornerstones of the modern collaborative pianist’s repertoire. My dissertation explored both the art songs and the piano quartets of these three composers and studied the different skills needed by a pianist performing both types of works. This project included the following art song cycles: Robert Schumann’s Dichterliebe, Gabriel Fauré’s Poème d’un Jour, and Johannes Brahms’ Zigeunerlieder. I also performed Schumann’s Piano Quartet in E-flat Major, Op. 47, Fauré’s Piano Quartet in C minor, Op. 15, and Brahms’ Piano Quartet in G minor, Op. 25. My collaborators included: Zachariah Matteson, violin and viola; Kristin Bakkegard, violin; Molly Jones, cello; Geoffrey Manyin, cello; Karl Mitze, viola; Emily Riggs, soprano, and Matthew Hill, tenor. This repertoire was presented over the course of three recitals on February 13, 2015, December 11, 2015, March 25, 2016 at the University of Maryland’s Gildenhorn Recital Hall. These recitals can be found in the Digital Repository at the University of Maryland (DRUM).
