    • We present a novel age-equation calibration for fission-track age determinations by laser ablation inductively coupled plasma mass spectrometry. This new calibration incorporates the efficiency factor of an internal surface, [ηq]is, which is obtained by measuring the projected fission-track length, allowing the determination of FT ages directly using the recommended spontaneous fission decay constant. Also, the uranium concentrations in apatite samples are determined using a Durango (Dur-2, 7.44 μg/g U) crystal and a Mud Tank (MT-7, 6.88 μg/g U) crystal as uranium reference materials. The use of matrix-matched reference materials allows a reduction in the uncertainty of the uranium measurements to those related to counting statistics, which are ca. 1 % taking into account that no extra source of uncertainty has to be considered. The equations as well as the matrix-matched reference materials are evaluated using well-dated samples from Durango, Fish Canyon Tuff, and Limberg as unknown samples. The results compare well with their respective published ages determined through other dating methods. Additionally, the results agree with traditional fission-track ages using both the zeta approach and the absolute approach, suggesting that the calibration presented in this work can be robustly applied in geological context. Furthermore, considering that fission-track ages can be determined without an age standard sample, the fission-track thermochronology approach presented here is assumed to be a valuable dating tool.

  • Challenges of implementing the Paediatric Surviving Sepsis Campaign International Guidelines 2020 in resource-limited settings: A real-world view beyond the academia
  • 2021
  • In: Andes pediatrica : revista Chilena de pediatria. - : Sociedad Chilena de Pediatria. - 2452-6053. ; 92:6, s. 954-962

    • Las Guías Internacionales de la Campaña Sobreviviendo a la Sepsis para el Manejo del Shock Séptico y la Disfunción de Órganos Asociada a la Sepsis en Niños, fueron publicadas en 2020 y están desti- nadas a ser utilizadas en todos los lugares que atienden a niños. Sin embargo, los profesionales que atienden a los niños con sepsis en entornos con recursos limitados se enfrentan a una serie de desafíos y perfiles de enfermedad distintos a los que se encuentran en entornos ricos en recursos. Basándonos en nuestra experiencia colectiva en entornos con recursos limitados, nos propusimos reflexionar so- bre las dificultades de aplicar las directrices internacionales. Creemos que hay una necesidad urgente de más evidencia de entornos con recursos limitados en enfoques factibles y eficaces para el trata- miento de la sepsis y el shock séptico que podrían incluirse en las futuras directrices para situaciones y contextos específicos.
