Dilatative percutaneous tracheostomy during double antiplatelet therapy: two consecutive cases.
No full textThis article reports two cases of dilatative percutaneous tracheostomy performed on patients treated with double antiplatelet therapy. Both patients had cardiac arrest following myocardial infarction. After primary angioplasty with stent placement, a double antiplatelet therapy was started. Due to poor neurological outcome, dilatative percutaneous tracheostomy was performed on both patients. Antiplatelet therapy was not discontinued because of the unacceptable risk of stent thrombosis. No immediate or late hemorrhagic complications occurred. In our experience, dilatative percutaneous tracheostomy during double antiplatelet therapy can be safely performed in selected patients without other risk factors
Activities of a medical emergency team twenty years after its introduction
No full textINTRODUCTION:We describe and quantify the wide range of activities that a mature Medical Emergency Team can progressively perform.METHODS:The activities performed by a Medical Emergency Team 20 years after its introduction were prospectively collected during 105 consecutive days.RESULTS:The main activity was focused on the follow-up visits to previously treated critically ill patients (mean 7.5 visits/die in working days, 5.1 in the others). A large amount of other scheduled or unscheduled activities (like sedation or analgesia for diagnostic procedures, central venous line placement, phone consultation regarding critical care aspects of treatments) were performed: on average, 7.3 side-activities/die in working days and 5.2 in the others. First consultations in patients not previously seen were on average 3.1/die on working days, 2.4 in the others. Cardiac arrest accounted for 27 (9%) of first time visits.CONCLUSIONS:A Medical Emergency Team can progressively perform many kinds of activities. An evaluation limited to the reduction of in-hospital cardiac arrests or a too early assessment may underestimate its beneficial effects on the Hospital complexit
Medical emergency team and non-invasive ventilation outside ICU for acute respiratory failure
No full textObjective: To report
data about ‘‘real-life’’ treatments with
non-invasive ventilation for acute
respiratory failure (ARF), managed
outside intensive care units by anaesthesiologists
acting as a medical
emergency team. Design: Observational
study; prospectively collected
data over a 6-month period in a single
centre. Setting: Non-intensive
wards in a University Hospital with
1,100 beds. Patients: Consecutive
patients with ARF for whom a ventilatory
support was indicated but
tracheal intubation was not appropriated
or immediately needed.
Interventions: None. Measurements
and results: Patient’s characteristics,
safety data, short-term outcome
and organizational aspects of 129
consecutive treatments were collected.
The overall success rate was 77.5%,
while 10.1% were intubated and
12.4% died (all of them were ‘‘do not
attempt resuscitation’’ patients). The
incidence of treatment failure varied
greatly among different diseases.
Complications were limited to nasal
decubitus (5%), failure to accomplish
the prescribed ventilatory program
(12%), malfunction of the ventilator
(2%) and excessive air leaks from face
mask (2%) with no consequences for
patients. Three patients became intolerant
to NIV. The work-load for the
MET was high but sustainable: on
average NIV was applied to a new case
every 34 h and more than three
patients were simultaneously treated.
Conclusions: Under the supervision
of a MET, in our institution NIV could
be applied in a wide variety of settings,
outside the ICU, with a high success
rate and with few complications
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
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
