Comparison of two European paediatric emergency departments: does primary care organisation influence emergency attendance?
No full textBackround:
To compare paediatric Emergency Department (ED) attendances and admission outcomes in twoEuropean hospitals with different paediatric primary care set-up.
Methods:
This is a retrospective prevalence study comparing all paediatric ED attendances during calendar years 2013 in two EDs with similar catchment area: one in Italy (Trieste) where paediatric primary care is provided by
office paediatricians, the other, in the UK (Cambridge), where paediatric primary care is provided by general practitioners. Data on reason for presentation, discharge diagnosis and admission rate were collected and
sub-group analysis for specific age groups (<1 year, 1 – 4 years, 5 – 15 years) was performed. Results:
Over 12 months, 20.331 children (0 – 15 years old) were seen in Cambridge and 18.646 in Trieste, with a very similar age distribution in both centres, except for the youngest age group: the percentage of infants seen in
comparison with the total number of children attending ED was 1/3 higher in England than in Italy (15.4% vs 11. 4%). The reasons for attendance were similar: under 1 year of age, the chief complaints were fever, breathing
difficulties and gastrointestinal problems while in the older age groups trauma represented the commonest reason. Among discharge diagnoses, no differences were found between the two hospitals, except for faltering growth and “ well child ” , more frequently diagnosed in English children under 5 years. The proportion of admissions was three times higher in Cambridge (14.1% vs 4.8%) with most children being admitted for infectious diseases.
Conclusions:
ED attendances in infants are more common in a primary care setting provided by general practicioner and, moreover, admission rates in all age groups are 1/3 reduced by primary care based paediatricians. Due to the methodological limits of this study, it isn't possible to evaluate whether these results depend only on paediatric primary care set-up or be determined by other confounding factors. New studies are needed to confirm
this preliminary evidence
Design production and test of the BaBar SVT fanouts
No full textThe Silicon Vertex Tracker (SVT) of the BaBar experiment at the PEP-II B-factory at SLAG plays a fundamental role for the CP-violation measurement. The SVT is made of five layers of double-sided silicon microstrip detectors covering the polar angles between 17.2 degrees and 150 degrees (in the Upsilon(4S) center-of-mass reference frame this corresponds to -0.95 < cos theta < 0.87).
Due to mechanical constraints, the strip signals must be brought to the readout electronics with flexible Upilex circuits (fanouts) where copper traces are deposited with a pitch of approximate to 50 mu m.
We present here a detailed description of the mechanical and electric characteristics of these fanouts, with particular attention on the test system that has been designed in order to control the quality of the production
Comparative neuroanatomy of extinct horned turtles (Meiolaniidae) and extant terrestrial turtles (testudinidae), with comments on the palaeobiological implications of selected endocranial features
No full textTurtles are one of the least explored clades of reptiles with respect to palaeoneuroanatomy. Few detailed descriptions of endocranial features such as the brain morphology or inner ear exist for extant and extinct forms. In this contribution, we present the first CT-based reconstructions of endocranial morphology (brain and inner ear) and the nasal cavities in the terrestrial horned meiolaniid (Meiolaniidae) turtles Niolamia argentina and Gaffneylania auricularis from the Eocene of Patagonia, as well as Meiolania platyceps from the Pleistocene of Lord Howe Island, Australia. In addition, these exclusively Gondwanan Cenozoic taxa are contrasted with cranial endocasts of multiple extant testudinoids, thereby providing the largest sample of digital comparative endocranial data assembled for extinct and living turtles to date. Our study thus adds much needed anatomical information on turtle palaeoneurology. Aspects of meiolaniid palaeobiology are discussed; in particular, the hypertrophied nasal cavity might not to be related to olfactory acuity, but rather perhaps adaptation to arid climatic conditions, and/or intraspecific behaviours.Fil: Paulina Carabajal, Ariana.
