Herein we add first country records to Panama’s microcaddisfly fauna (Trichoptera, Hydroptilidae), one genus— Orthotrichia Eaton, 1873—and 12 species— Alisotrichia latipalpis Flint, 1991; Hydroptila constricta Bueno-Soria, 1984; Metrichia decora Bueno-Soria & Holzenthal, 2003; malada (Flint, 1991); Neotrichia amplector Keth, 2004; armata Botosanea...

Diastolic murmurs associated with the Starr-Edwards mitral prosthesis have not been described previously. In this report, five patients with mitral prostheses are described in whom apical mid-diastolic and presystolic murmurs resulted from two different causes. Three patients had clots obstructing the prosthetic orifice. The other two had normally functioning protheses and moderately severe aor...

Hemodynamic data from 45 patients with either aortic regurgitation (with and without the Austin Flint murmur) or aortic regurgitation and mitral stenosis were correlated with the a-wave percentage amplitude of the apexcardiogram. Changes in the a wave correlated well with corresponding changes in left heart pressures but not with variations in volume. Of 15 patients in whom the ratio of the a w...

In 2014, the city of Flint, MI, in USA changed its public water source, resulting severe contamination and a health crisis. Using Flint crisis as natural experiment, we estimate effect utero exposure to polluted on at birth. Matching vital statistics birth records with various sources data, use synthetic control method identify causal impact pollution key outcomes. Our results suggest that mode...
