Väga väikese gestatsioonivanusega enneaegsed lapsed Eestis: ravitulem ja prognostilised tegurid
Get PDFVäitekirja elektrooniline versioon ei sisalda publikatsioone.Meditsiini arenguga on suurenenud VVGV (sünd <32. täisrasedusnädalat) vastsündinute elulemus, kuid lapsed on ohustatud erinevatest arenguhäiretest. VVGV laste tervisetulemit 2 aasta vanuses peetakse perinataalabi kvaliteedi oluliseks indikaatoriks.
Uurimistöö eesmärkideks oli kirjeldada VVGV laste ravitulemit ja ägedat respiratoorset haigestumist Eestis, leida ebasoodsa tulemi riskitegurid ning hinnata riigi peri- ja neonataalabi kvaliteeti.
Rahvastikupõhine edasivaatav kohortuuring hõlmas aastatel 2007-2008 sündinud 360 VVGV last. Perinataalsed andmed saadi neonataalsest uuringuregistrist. Varast tulemit esmase haiglaravi lõpul võrreldi 264 VVGV lapse võrdluskohordiga aastatest 2002-2003. Hilist tulemit enneaegsusele korrigeeritud 2 aasta vanuses hinnati 2007. aastal sündinud 155-l VVGV lapsel ja võrreldi ajalisena sündinud laste tulemiga. Järelkontrollil hinnati laste somaatilist, neurosensoorset ja arengulist tulemit. Äge respiratoorne haigestumus selgitati vanemate küsitluse teel.
Uuringuperioodidel suurenes oluliselt VVGV laste elulemus (78 vs 85%), kusjuures perinataalabi oli hilisemal perioodil proaktiivsem ja neonataalne ravi vähem invasiivne. Elulemuse paranemisega püsis neonataalsete haigustega elulejate osakaal muutumatuna, kuid võrreldes kõrge sissetulekuga riikidega suhteliselt suurena. Järelkontrollil esines mõõdukas/raske arenguhäire 12%-l VVGV lastest: tserebraalparalüüs 8%-l, kognitiivse arengu mahajäämus 5%-l ja kõne arengu mahajäämus 10%-l. Kognitiivse, kõne ja motoorse arengu keskmine koondskoor Bayley testil oli VVGV lastel 0,5 SD võrra madalam kui ajalisena sündinutel. Samuti olid oluliselt väiksemad VVGV laste keskmine kaal, pikkus ja peaümbermõõt ning ägeda respiratoorse haigestumise korral esines neil oluliselt enam vilistavat hingamist ning haiglaravi vajadust.
Ebasoodsa tervisetulemi peamiseks riskiteguriks oli hiliseid puudeid ennustavate neonataalsete haiguste põdemine esmasel haiglaravil.
VVGV laste elulemus Eestis on võrdväärne arenenud meditsiiniabiga riikidega, kuid laste varane haigestumus ja tervisehäirete esinemine 2 aasta vanuses jääb osaliselt suuremaks. Tervishoiu peamiseks väljakutseks on vähendada VVGV enneaegsete neonataalset haigestumist, säilitades suure elulejate osakaalu.Advances in perinatal care have improved the survival of VLGA (born <32 weeks' gestation) infants dramatically, but these infants remain at substantial risk for a wide spectrum of long-term morbidities. Therefore, it is mandatory that any assessment of quality of care for VLGA infants includes the long-term outcome.
The aims of the studies were to describe outcome and acute respiratory morbidity of VLGA infants in Estonia, to identify risk factors for adverse outcome, and to benchmark the quality of perinatal services in the country.
A nationwide prospective cohort study comprised 360 live-born VLGA infants born in Estonia in 2007–2008. Perinatal data were collected to the neonatal research register. A historical cohort of 264 VLGA infants born in 2002–2003 was selected for analysis of changes in the short-term outcome. A sub-cohort of 155 surviving VLGA infants born in 2007 was compared with a matched full-term control group at 2 years of corrected age. The infants underwent physical, neurological, and developmental assessment. Acute respiratory morbidity was identified by parental interviews.
The survival until discharge increased significantly (78% in 2002-2003 vs 85% in 2007-2008) with proactive perinatal management and less invasive neonatal care and without concomitant increases in neonatal morbidity. However, the morbidity rates were higher when compared with comparable data from high income countries. At follow-up, neurodevelopmental impairment was noted in 12% of VLGA infants, with 8% affected by cerebral palsy, 5% with cognitive delay, and 10% with language delay. The mean Cognitive, Language, and Motor Composite Scores assessed using the Bayley-III scales were in VLGA group in excess of 0.5 SD lower than in full-term infants. Wheezing during respiratory infections and somatic growth failure were significant problems among VLGA infants.
Major neonatal morbidities, predictive of poor long-term outcome, were the main risk factors for adverse outcomes.
The results showed that for VLGA infants in Estonia, the survival is comparable and the rates of early morbidities and impairments at 2 years are partly higher when compared to similar studies from high income countries. The challenge for perinatal services in Estonia is to reduce neonatal morbidity of VLGA infants without compromising their survival
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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
