Specimens recently submitted to the first author for identification turned out to represent two species of leaf beetles previously unknown from Florida, one of which is new to the eastern United States and the other new to the continental United States

New records, nomenclatural changes, and taxonomic notes for select North American leaf beetles (Coleoptera: Chrysomelidae)

New records, nomenclatural changes and taxonomic notes are presented for select North American leaf beetles (Coleoptera: Chrysomelidae). The following genera are newly recorded from the United States: Nesaecrepida Blake, 1964; Acallepitrix Bechyne, 1959; Margaridisa Bechyne, 1958; Parchicola Bechyne and Springlova de Bechyne, 1975; (all Galerucinae: Alticini); and Demotina Baly, 1874 (Eumolpinae). The following species are newly recorded from the United States: Neolema dorsalis (Olivier, 1791) (Criocerinae); Charidotella bifossulata Boheman, 1855 (Hispinae: Cassidini); Syphrea flauicollis (Jacoby, 1884) (Galerucinae: Alticini); and Promecosoma inflatum Lefevre, 1877, and Demotina modesta Baly, 1874 (Eumolpinae). The following new synonymies are proposed: Deloyala clauata, var. diuersicollis Schaeffer, 1925, transferred from synonymy with Plagiometriona clauata (Fabricius, 1798) to synonymy withP. clauata testudinaria (Boheman, 1855); Chrysomela hybrida Say, 1824, downgraded from subspecies of Calligrapha lunata (Fabricius, 1787) to full synonym of CaZZigrapha lunata (Fabricius); Chrysomela casta Rogers, 1856, downgraded from subspecies of Zygogramma suturalis (Fabricius, 1775) to full synonym of Zygogrammasuturalis (Fabricius); Trirhabdagurneyi Blake, 1951, downgraded to synonym of Trirhabda caduca Horn, 1893; Scelida mimula Wilcox, 1965, downgraded to synonym of Scelida nigricornis (Jacoby, 1888); Exoracalifornica Wilcox, 1953, downgraded to synonym of Pte leon breuicornis (Jacoby, 1887); alaeothonaarizonensis Blake, 1950, downgraded to synonym ofLupraea discrepans (Schaeffer, 1932); Haltica nigritula Linell, 1898, downgraded to synonym of Nesaecrepida asphalt ina (Suffrian, 1868); Cryptocephalus reinhardi Sundman, 1965, downgraded to synonym of Cryptocephalus nwtabilis Melsheimer, 1847. The tribes Chalepini Wiese, 1910, and Uroplatini Weise, 1910 (Hispinae), are synonymized, and both of these family-group names are recognized as nomina protecta. The family-group name Octotomites Chapuis, 1875, is recognized as a nomen oblitum. Coptocycla testudinaria Boheman, 1855, is downgraded from specific status to a subspecies of Plagiometriona clauata (Fabricius, 1798); Cassida bicolor (Fabricius, 1798) is recognized as a valid subspecies of Charidotellasexpunctata (Fabricius). The genus Hemiphrynus Horn, 1889, is removed from synonymy with Phrynocepha and reinstated as a valid genus; Rhabdopterus weisei (Schaeffer, 1920) is removed from synonymy with Rhabdopterus praetextus (Say) and reinstated as a valid species. The following new combinations are proposed: Synetocephalus wallacei (Wilcox, 1965), transferred from Pseudoluperus; Nesaecrepida infuscata (Schaeffer, 1906), transferred from Monomacra; Acallepitrix nitens (Horn, 1889), transferred from Epitrix; Margaridisa atriuentris (Melsheimer, 1847), transferred from Hornaltica; Parchicola iris (Olivier, 1808) and P. tibialis (Olivier, 1808), transferred from Monomacra; and Coleothorpa panochensis (Gilbert, 1981), transferred from Coscinoptera; Promecosoma arizonae (Crotch, 1873), transferred from Metaxyonycha; Tymnes chrysis (Olivier, 1808), T. oregonensis (Crotch, 1873), and T. thaleia (Blake, 1977), transferred from Colaspis. The following new replacement name is proposed: Triarius nigroflaulls, for Luperodes flauoniger Blake, 1942 (not Laboissiere, 1925). The identities of Griburius equestris (Olivier, 1808) and G. laruatlls (Newman, 1840) are discussed

How I prescribe prolonged intermittent renal replacement therapy

Prolonged Intermittent Renal Replacement Therapy (PIRRT) is the term used to define \u27hybrid\u27 forms of renal replacement therapy. PIRRT can be provided using an intermittent hemodialysis machine or a continuous renal replacement therapy (CRRT) machine. Treatments are provided for a longer duration than typical intermittent hemodialysis treatments (6-12 h vs. 3-4 h, respectively) but not 24 h per day as is done for continuous renal replacement therapy (CRRT). Usually, PIRRT treatments are provided 4 to 7 times per week. PIRRT is a cost-effective and flexible modality with which to safely provide RRT for critically ill patients. We present a brief review on the use of PIRRT in the ICU with a focus on how we prescribe it in that setting

Prevalence of and Factors Associated with Negative Microscopic Diagnosis of Cutaneous Leishmaniasis in Rural Peru.

Cutaneous leishmaniasis is endemic to South America where diagnosis is most commonly conducted via microscopy. Patients with suspected leishmaniasis were referred for enrollment by the Ministry of Health (MoH) in Lima, Iquitos, Puerto Maldonado, and several rural areas of Peru. A 43-question survey requesting age, gender, occupation, characterization of the lesion(s), history of leishmaniasis, and insect-deterrent behaviors was administered. Polymerase chain reaction (PCR) was conducted on lesion materials at the Naval Medical Research Unit No. 6 in Lima, and the results were compared with those obtained by the MoH using microscopy. Factors associated with negative microscopy and positive PCR results were identified using

Modes of Global Climate Variability during Marine Isotope Stage 3 (60–26 ka)

Recent analysis of 38 globally distributed paleoclimatic records covering Marine Isotope Stage 3 (MIS 3) 60–26 ka demonstrated that the two leading empirical orthogonal functions (EOFs) explaining the data are the Greenland ice-core signal (“northern” signal) and the Antarctic ice-core signal (“southern” signal). Here singular spectral analysis (SSA) is used to show that millennial-scale variability of each of these two leading EOFs is characterized by two independent modes. The two modes of each EOF share similar relative distributions of variance, identical spectra, and, where each mode has spectral power, coherency spectra, which are significantly above the null hypothesis level at 95% confidence. The only difference between the modes of the northern and southern signals is that they are phase shifted. The phasing and long response time of the low-frequency mode, combined with its relationship to atmospheric CO2 and sea level, are consistent with coupled changes in the ocean, ice sheets, atmosphere, and carbon cycle, whereas the phasing and short response time of the high-frequency mode are consistent with an atmospheric transmission likely induced by changes in hemispheric sea ice distributions and attendant feedbacks.Keywords: Empirical orthogonal functions, Climate variabilit
