RESUMO
Identify alterations in gene expression unique to systemic and kidney-specific pathophysiologic processes using whole-genome analyses of RNA isolated from the urinary cells of sepsis patients. DESIGN: Prospective cohort study. SETTING: Quaternary care academic hospital. PATIENTS: A total of 266 sepsis and 82 control patients enrolled between January 2015 and February 2018. INTERVENTIONS: Whole-genome transcriptomic analysis of messenger RNA isolated from the urinary cells of sepsis patients within 12 hours of sepsis onset and from control subjects. MEASUREMENTS AND MAIN RESULTS: The differentially expressed probes that map to known genes were subjected to feature selection using multiple machine learning techniques to find the best subset of probes that differentiates sepsis from control subjects. Using differential expression augmented with machine learning ensembles, we identified a set of 239 genes in urine, which show excellent effectiveness in classifying septic patients from those with chronic systemic disease in both internal and independent external validation cohorts. Functional analysis indexes disrupted biological pathways in early sepsis and reveal key molecular networks driving its pathogenesis. CONCLUSIONS: We identified unique urinary gene expression profile in early sepsis. Future studies need to confirm whether this approach can complement blood transcriptomic approaches for sepsis diagnosis and prognostication.
RESUMO
We revise the genus Prespelea Park, redefining and redescribing the two previously known species, P. copelandi Park and P. quirsfeldi Park, and adding ten new species: P. parki Caterino & Vásquez-Vélez, sp. n., P. minima Caterino & Vásquez-Vélez, sp. n., P. morsei Caterino & Vásquez-Vélez, sp. n., P. divergens Caterino & Vásquez-Vélez, sp. n., P. carltoni Caterino & Vásquez-Vélez, sp. n., P. myersae Caterino & Vásquez-Vélez, sp. n., P. georgiensis Caterino & Vásquez-Vélez, sp. n., P. enigma Caterino & Vásquez-Vélez, sp. n., P. wagneri Caterino & Vásquez-Vélez, sp. n., and P. basalis Caterino & Vásquez-Vélez, sp. n.. The genus is still only known from a relatively small area in the southern Appalachian Mountains, but the diversity is much greater than previously suspected. The new species exhibit considerable diversity in male secondary sexual characters. A preliminary phylogenetic analysis cannot conclusively resolve the polarity of eye and wing reduction across Speleobamini, but the monophyly of Park's subgenus Fusjugama, if expanded to include all species with full-eyed and winged males, is not supported, and we therefore synonymize it with Prespeleas. str.

RESUMO
In my revision of the genus Pselaphomorphus Motschulsky, 1855 (Vásquez-Vélez 2016) the depository of the holotype of P. cayennensis Vásquez-Vélez, 2016 was not listed. As a result, the requirements of Article 16.4.2 of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999) have not been met, making the name unavailable. This note aims at correcting the earlier mistake: the holotype of P. cayennensis is deposited at the Museum of natural history (Muséum d'histoire naturelle), Geneva, Switzerland.

The genus Pselaphomorphus Motschulsky, 1855 is revised to include 33 species. The type species, Pselaphomorphus sculpturatus Motschulsky, 1855, and the previously described species P. longiceps Raffray, 1890 and P. microphthalmus Raffray, 1890 are redescribed, and the original description of P. brevipennis Raffray, 1917 and P. bruchi Raffray, 1918 are translated from Latin and French to English. The following species are described as new: P. acutispinosus n. sp. from Peru, P. agametopus n. sp. from Colombia, P. azuayensis n. sp. from Ecuador, P. bolivarensis n. sp. from Venezuela, P. breviantennae n. sp. from Bolivia, P. carenobothrus n. sp. from Peru, P. carltoni n. sp. from Ecuador, P. cayennensis n. sp. from French Guiana, P. chandleri n. sp. from Panama, P. fluminosus n. sp. from Venezuela, P. iguazuensis n. sp. from Argentina, P. incorum n. sp. from Peru, P. longissimus n. sp. from Panama, P. macrommatus n. sp. from Ecuador, P. maldonadensis n. sp. from Peru, P. mayaorum n. sp. from Honduras, P. melanus n. sp. from Costa Rica, P. montsineryensis n. sp. from French Guiana, P. motschulskyi n. sp. from Costa Rica, P. newtoni n. sp. from Brazil, P. parki n. sp. from Costa Rica, P. raffrayi n. sp. from Peru, P. santaecrucis n. sp. from Bolivia, P. simplicipenis n. sp. from French Guiana, P. thayerae n. sp. from Brazil, P. tucumanensis n. sp. from Argentina, P. veracruzanus n. sp. and P. wagneri n. sp., both from Mexico.
