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

Acute neuromuscular respiratory failure after ICU discharge. Report of five patients
No full textObjective: To describe a syndrome of acute neuromuscular respiratory failure (NM-ARF) caused by ICU-acquired acute myopathy and neuropathy. Design: Case series. Setting: General Regional University Hospital in Brescia, Italy. Patients: Five adult patients with NM-ARF after prolonged ICU stay and successful weaning from the ventilator and ICU discharge. Interventions: None. Measurements: Clinical signs of NM-ARF electroneurography and electromyography (ENMG) of peripheral nerves and muscles, and functional assessment of respiratory muscles. Results: NM-ARF was diagnosed at the time of (one case), or 1-3 days after, ICU discharge. Limb weakness alarmed the physicians, while the signs of the NM-ARF were initially undetected. In the first observed case the acute respiratory failure was near fatal, and necessitated ICU readmission, while in the other cases 2 weeks of aggressive chest physiotherapy permitted resolution of the respiratory failure
