A First Search for coincident Gravitational Waves and High Energy Neutrinos using LIGO, Virgo and ANTARES data from 2007
We present the results of the first search for gravitational wave bursts
associated with high energy neutrinos. Together, these messengers could reveal
new, hidden sources that are not observed by conventional photon astronomy,
particularly at high energy. Our search uses neutrinos detected by the
underwater neutrino telescope ANTARES in its 5 line configuration during the
period January - September 2007, which coincided with the fifth and first
science runs of LIGO and Virgo, respectively. The LIGO-Virgo data were analysed
for candidate gravitational-wave signals coincident in time and direction with
the neutrino events. No significant coincident events were observed. We place
limits on the density of joint high energy neutrino - gravitational wave
emission events in the local universe, and compare them with densities of
merger and core-collapse events.Comment: 19 pages, 8 figures, science summary page at

Mechanical ventilation in adults with acute respiratory distress syndrome: An official clinical guideline of American Thoracic Society/European Society of Intensive Care medicine/Society of Critical care medicine
The aim of this guideline is to provide clinical recommendation on the use of mechanical ventilation in adult patients with acute respiratory distress syndrome (ARDS). Methods. This guideline is based on systematic review and metaanalysis of available literature on the use of mechanical ventilation in adult patients with ARDS. Results. All patients with ARDS should be mechanically ventilated with the use of lower tidal volumes (4\u20138 ml/kg predicted bodyweight) and lower inspiratory pressures (plateau pressure, 30 cm H2O). In severe ARDS, the prone positioning for more than 12 h/d is strongly recommended. In patients with moderate to severe ARDS, routine use of high-frequency oscillatory ventilation is not recommended; conditional recommendation has been developed for the use of higher positive end-expiratory pressure and recruitment maneuvers. Cu?? \u2013 ently, there is not enough evidence for the use of extracorporeal membrane oxygenation in patients with severe ARDS. Conclusions. Practical recommendations on selected methods to co?? \u2013 ect ventilation disturbances in adult patients with ARDS have been developed. Clinicians involved in the management of patients with ARDS should use personalized approach to the treatment of these patients.

An official American Thoracic Society/European Society of intensive care medicine/society of critical care medicine clinical practice guideline : mechanical ventilation in adult patients with acute respiratory distress syndrome
Background: This document provides evidence-based clinical practice guidelines on the use of mechanical ventilation in adult patients with acute respiratory distress syndrome (ARDS). Methods: A multidisciplinary panel conducted systematic reviews and metaanalyses of the relevant research and applied Grading of Recommendations, Assessment, Development, and Evaluation methodology for clinical recommendations. Results: For all patients with ARDS, the recommendation is strong for mechanical ventilation using lower tidal volumes (4-8 ml/kg predicted body weight) and lower inspiratory pressures (plateau pressure < 30 cm H2O) (moderate confidence in effect estimates). For patients with severe ARDS, the recommendation is strong for prone positioning for more than 12 h/d (moderate confidence in effect estimates). For patients with moderate or severe ARDS, the recommendation is strong against routine use of high-frequency oscillatory ventilation (high confidence in effect estimates) and conditional for higher positive end-expiratory pressure (moderate confidence in effect estimates) and recruitment maneuvers (low confidence in effect estimates). Additional evidence is necessary to make a definitive recommendation for or against the use of extracorporeal membrane oxygenation in patients with severe ARDS. Conclusions: The panel formulated and provided the rationale for recommendations on selected ventilatory interventions for adult patients with ARDS. Clinicians managing patients with ARDS should personalize decisions for their patients, particularly regarding the conditional recommendations in this guideline
