Noves aportacions dels Elasmus Westwood a la Península Ibèrica, Illes Balears i Canàries. (Hymenoptera: Chalcidoidea: Elasmidae)

En aquest estudi es citen les espècies pertanyents al gènere Elasmus detectades a partir de material divers procedent del territori espanyol. En total han estat identificades 8 espècies de les 23 presents a Europa. Es citen per primera vegada espècies d'elàsmids a les illes Balears i a les Canàries, així com es cita per primer cop a Espanya Elasmus arcuatus Ferrière, 1947. S'amplia la distribució peninsular de les espècies: E. cyprianus (Ferrière, 1947), E. Flabellatus (Fonscolombe, 1832), E. Fulviceps (Graham, 1995), E. Nowickii (Ferrière, 1947), E. platyedrae (Ferrière, 1935), E. Rufiventris (Ferrière, 1947), E. Steffani (Viggiani, 1967), i E. Viridiceps (Thompson, 1878). Finalment es comenta la problemàtica d'identificació d'algunes de les espècies de la família.New records of Elasmus Westwood, (Hymenoptera: Chalcidoidea: Elasmidae) in the Iberian Peninsula, Balearic and Canary Islands. The family Elasmidae has a world-wide distribution. It comprises two genera in Europe, Elasmus Westwood, 1833 and Euryschia Riley, 1889, and more than 100 species. Here we study the species of the genus Elasmus collected in several localities in Spain. A total of 8 species among the 23 known in Europe were found. This is the first record of these species in the Balearic or Canary Islands, and also the first record of Elasmus arcuatus Ferrière, 1947 in Spain. The peninsular distribution of E. Cyprianus (Ferrière, 1947), E. flabellatus (Fonscolombe, 1832), E. Fulviceps (Graham, 1995), E. Nowickii (Ferrière, 1947), E. Platyedrae (Ferrière, 1935), E. Steffani (Viggiani, 1967), E. Rufiventris (Ferrière, 1947), and E. Viridiceps (Thompson, 1878) is extended. Moreover, problems to identify some species of the family are commented

Abstract not availabl

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation
