Systematic revision and phylogeny of the South American sun-spider genus Gaucha Mello-Leitão (Solifugae: Mummuciidae), with description of four new species and two new generic synonymies

The South American sun-spider genus Gaucha Mello-Leitão, 1924 is herein studied from a combined approach of cladistics and traditional taxonomy. This is the first cladistic analysis for a group of mummuciid solifuges, and it is pioneer in integrating traditional morphological characters with landmark data for inferring the phylogeny of any group of Solifugae. As a result, Gaucha is redefined and its monophyly demonstrated. Gaucha fasciata Mello-Leitão, 1924, type species of this formerly monotypic genus, is redescribed based on specimens from the type locality, in Rio Grande do Sul, Brazil. Three new species are described from Brazil: Gaucha avexada sp.nov. from Bahia and Tocantins, Gaucha curupi sp.nov. from Rio Grande do Sul, and Gaucha eremolembra sp.nov. from Minas Gerais. A fourth new species, Gaucha casuhati sp.nov., is described from Buenos Aires province, Argentina. In addition, Metacleobis Roewer, 1934 and Gauchella Mello-Leitão, 1937 are synonymized with Gaucha, following the examination of the type specimens and based upon evidence from the cladistic analysis. Gaucha fulvipes (Roewer, 1934) comb.nov., from Mato Grosso (Brazil), is therefore proposed, whereas Gaucha stoeckeli Roewer, 1934 comb.rest., from Luribay (Bolivia), is restored into its original name combination. Gaucha ibirapemussu (Carvalho et al., 2010) comb.nov. and Gaucha mauryi (Rocha, 2001) comb.nov., from the Brazilian states of Piauí and Bahia, are also transferred, from Mummucia Simon, 1879. Gaucha is here defined, among other characters, by the large size of the cheliceral movable finger MP tooth as compared to MM tooth, and by the presence of a pronounced gnathal edge carina on the movable finger mucron of males. Two species groups are herein defined within the genus: the fasciata group, for G. casuhati sp.nov., G. curupi sp.nov., G. fasciata, G. fulvipes comb. nov. and G. stoeckeli comb.rest., and the ibirapemussu group, for G. avexada sp.nov., G. eremolembra sp.nov., G. ibirapemussu comb. nov. and G. mauryi comb.nov. A key to the identification of Gaucha species is included. Fil: Botero Trujillo, Ricardo. Consejo Nacional de Investigaciones Científicas y Técnicas.

Troglomorphic scorpion Troglotayosicus humiculum (Scorpiones, Troglotayosicidae).

19 p. : ill. (some col.), map ; 26 cm. "June 25, 2010." Includes bibliographical references (p. 18-19).The endemic Colombian troglomorphic scorpion, Troglotayosicus humiculum Botero-Trujillo and Francke, 2009, previously known only from the juvenile holotype, is redescribed based on newly collected adults of both sexes. New data on basitarsal spination, telotarsal setation, and carination of the metasoma and pedipalps, together with the first description of the hemispermatophore and a revised interpretation of the trichobothria, are provided, along with brief discussions of the ecology and distribution of the species

Aspectos biológicos del género Brachistosternus (Bothriuridae) en el Desierto de Atacama (Chile), con la descripción de un nuevo tipo de macroseta de los pedipalpos

New data about several aspects of the biology of scorpions of genus Brachistosternus of the Atacama Desert are provided. Predatory techniques on tenebrionid larvae, and large spiders in their burrows are described, as well as the method used to transport large preys. The habitat of Brachistosternus mattonii Ojanguren-Affilastro 2005, by the tide line, is described for the first time. Finally a new type of pedipalp macroseta of Bothriuridae is described.Se presentan nuevos datos sobre distintos aspectos de la biología de los escorpiones del género Brachistosternus del desierto de Atacama. Se describen las técnicas predatorias sobre las larvas de tenebriónidos y sobre grandes arañas en sus túneles, así como el método utilizado para transportar grandes presas. El hábitat de Brachistosternus mattonii Ojanguren- Affilastro 2005, a lo largo de la línea de marea, es descripto por primera vez. Finalmente un nuevo tipo de macroseta de los pedipalpos de Bothriuridae es descripto

Design and baseline characteristics of the finerenone in reducing cardiovascular mortality and morbidity in diabetic kidney disease trial

Background: Among people with diabetes, those with kidney disease have exceptionally high rates of cardiovascular (CV) morbidity and mortality and progression of their underlying kidney disease. Finerenone is a novel, nonsteroidal, selective mineralocorticoid receptor antagonist that has shown to reduce albuminuria in type 2 diabetes (T2D) patients with chronic kidney disease (CKD) while revealing only a low risk of hyperkalemia. However, the effect of finerenone on CV and renal outcomes has not yet been investigated in long-term trials. Patients and Methods: The Finerenone in Reducing CV Mortality and Morbidity in Diabetic Kidney Disease (FIGARO-DKD) trial aims to assess the efficacy and safety of finerenone compared to placebo at reducing clinically important CV and renal outcomes in T2D patients with CKD. FIGARO-DKD is a randomized, double-blind, placebo-controlled, parallel-group, event-driven trial running in 47 countries with an expected duration of approximately 6 years. FIGARO-DKD randomized 7,437 patients with an estimated glomerular filtration rate >= 25 mL/min/1.73 m(2) and albuminuria (urinary albumin-to-creatinine ratio >= 30 to <= 5,000 mg/g). The study has at least 90% power to detect a 20% reduction in the risk of the primary outcome (overall two-sided significance level alpha = 0.05), the composite of time to first occurrence of CV death, nonfatal myocardial infarction, nonfatal stroke, or hospitalization for heart failure. Conclusions: FIGARO-DKD will determine whether an optimally treated cohort of T2D patients with CKD at high risk of CV and renal events will experience cardiorenal benefits with the addition of finerenone to their treatment regimen.
