Breastfeeding the 'healthy' near-term infants after laryngeal mask airway or traditional resuscitation methods
No full textBackground. The influence of delivery room resuscitation practice on neonatal breastfeeding pattern is largely not data driven, and clinical experience is insufficient to indicate the impact of available management methods. Aim. This cohort observational study investigated weather laryngeal mask airway LMA rather conventional positive pressure resuscitation devices, face mask FM, or endotracheal-tube ETT would influence breastfeeding pattern in the near-term infants triaged to regular newborn nursery. Methods. We identified through 18,641 birth records from 2002 to 2006, 921 4.9 records of near-term infants of 3436 67 weeks' gestation, 710 77.1 triaged to regular newborn nursery. Among those, 52710 7.3 required positive pressure resuscitation at birth, inclusive of LMA 29, 55.7, bag-face mask FM, 19, 36.5, and endo-tracheal tube ETT, 4, 7.6, respectively. Fifty non-resuscitated near-term infants were used as controls. Results. Anthropometrical and clinical characteristics of resuscitated near-term study groups were comparable to controls. LMA was more frequently employed at birth to resuscitate near-term infants triaged to regular newborn nursery OR; 95 CI 17.16; 5.3455.14, whereas ETT was less frequently utilized OR; 95 CI 0.11; 0.020.55. Although LMA and ETT resuscitation methods did not influence breastfeeding rate at discharge with respect to controls, FM resuscitation was associated with both the lowest breastfeeding rate OR; 95 CI 3.20; 1.079.57 and the more frequently formula-feeding OR; 95 CI 7.23; 1.5832.92, and bottle-feeding use OR; 95 CI 4.20; 1.3013.49 at discharge. Conclusion. LMA is an effective and safe alternative to more conventional forms of airway management in near-term infants needing resuscitation at birth. Other studies are needed to clarify the potential advantages of the LMA on breastfeeding. © 2009 Informa UK Ltd
Delivery room resuscitation of near-term infants: Role of the laryngeal mask airway
No full textAim: This observational study aims to describe: (1) the use of positive pressure ventilation (PPV) for resuscitation in the delivery room among newly born near-term infants; (2) the methods used for PPV resuscitation [e.g., bag-facial mask (BFM), laryngeal mask airway (LMA), endotracheal tube (ETT)]; and (3) the association of each device with short-term neonatal outcomes. Methods: We identified near-term (34 0/7-36 6/7 weeks) infants delivered at the Padua University Hospital (Padua, Italy) during the years 2002-2006. The mode of delivery, gestational age, birth weight, Apgar scores, methods of resuscitation and respiratory outcome after NICU admission were analysed. Results: During the 5-year study period, 921 (4.9%) near-term infants were identified from a total of 18,641 live births. PPV was provided in the delivery room to 86 (9.3%) of these infants. Among them, 36 (41.8%) were managed by LMA, 34 (39.5%) by BFM and 16 (18.6%) by ETT. Thirty-four (39.5%) resuscitated near-term infants were admitted to the Neonatal Intensive Care Unit (NICU): 15 (44.1%) after BFM, 12 (75%) after ETT and seven (19.4%) after LMA. Resuscitation with an ETT was associated with an increased rate of respiratory distress syndrome when compared with either BFM or LMA. Resuscitation with an LMA was associated with a lower rate of NICU admission and shorter length of stay when compared with either BFM or ETT. Conclusion: The LMA is an effective device for primary airway management of near-term infants and for secondary airway management among near-term infants failing BFM or ETT resuscitation. © 2009 Elsevier Ireland Ltd
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
