Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Clinical applications of diaphragm ultrasound : moving forward
No full textEstablishing the correct time of weaning from mechanical ventilation is a crucial issue in the clinical practice. The difficult process of weaning can be due to pathological conditions that result in an imbalance between respiratory-muscle strength and respiratory load. Recently it has been suggested that ultrasound measurements of diaphragm muscle thickening in inspiration during weaning could provide an estimation of extubation success. Bedside ultrasonography, particularly sonographic evaluation of the diaphragm by measuring the percentage variation of diaphragm thickness (tdi) between end-inspiration and end-expiration (Δtdi%), has become a valuable tool in the management of intensive care unit patients. This non-invasive, low-cost and fast to perform technique seems to predict with a good accuracy the extubation failure. Some limitations derive from the difficulty to determine the maximum (end inspiratory) and minimum (end expiratory) tdi observing a dynamic image in B-mode, in particular in non-collaborating patients. In addition, some dynamic situations causing extubation failure could not be predicted by an ultrasound measure performed at the beginning of the weaning trial. Nowadays the technique proposed remains a useful tool for helping the prediction of extubation failure. It would be useful in the future to set up multicentric studies with a standardised description of the procedure and serial measurements in different timing during the weaning trial. Furthermore, randomized controlled trials to evaluate the efficiency of Δtdi% versus other indexes in predicting extubation failure are needed
