Evaluation of the possible protective effect of the copper intrauterine device and the levonorgestrel intrauterine system on the risk of precursor lesions and cervical cancer
No full textObjective: To evaluate copper intrauterine devices (IUDs) and levonorgestrel-releasing intrauterine systems
(LNG-IUS) as protective factors against cervical cancer
and precursor lesions. Methods: Case-control study, whose sample will be selected from women who have had at least one cytological examination for cervical cancer screening performed at the Family Planning Clinic of the Department of Obstetrics and Gynecology, School of Medical Sciences, State University of Campinas (UNICAMP).
We estimate that there will be 36,469 cases treated between 1999 and 2017. All women who have had a cytological examination will be considered cases. We estimate that
we will have 36,469 cases seen between 1999 and 2017. All women who had an abnormal cytological examination (cervical cancer or precursor lesions) during follow-up at the
outpatient clinic will be considered
as cases. This universe is estimated to be approximately 1,000 women
based on the information system of the Cytopathology Laboratory of CAISM,
UNICAMP. Women selected at the same outpatient clinic but with normal cytological tests throughout the follow-up period will be considered as controls. The total number of controls will be the same as the total number of cases. For pairing cases and controls, the criterion adopted will be the year of the cytological examination with abnormal results (cases), i.e., for each abnormal cytological examination, a woman will be selected
with a normal cytological examination performed in the same year,
immediately preceding and following the case
Fatores de risco para dor intensa na inserção de dispositivo intrauterino de cobre (TCu380a) e levonorgestrel (SIU-LNG) em usuárias do ambulatório de planejamento familiar da Unicamp
No full textObjetivos: Determinar fatores de risco para dor intensa durante a inserção do dispositivo intrauterino de cobre (TCu380A) e levonorgestrel (SIU-LNG) utilizando dados de fichas médicas, coletados entre os anos 2020 e 2024. Adicionalmente, avaliar se o uso de medicação antes ou depois do procedimento está associado a escores mais baixos de dor na inserção (0 a 6 na escala EVA).
Material e métodos: O estudo consistirá em uma revisão do banco de dados já existente de pessoas que inseriram DIU nos últimos 5 anos. Estimamos que em torno de 8000 mulheres entre 18-45 anos tenham registrado o grau de dor na inserção. Uma análise retrospectiva será conduzida usando regressão logística para examinar os fatores de risco para dor intensa imediatamente após a colocação do dispositivo. A dor será mensurada usando uma Escala Visual Analógica (EVA) variando de 0 (sem dor) a 10 (pior dor já vivenciada), e as pontuações serão classificadas como dor leve (1-3), dor moderada (4-6) e dor intensa (7-10). Fatores demográficos e clínicos, como idade, paridade, padrão menstrual e histórico obstétrico serão incluídos na análise de fatores de risco. Por fim, será investigada a potencial associação entre uso de medicação e dor, controlando potenciais efeitos de confusão de covariáveis relacionadas usando o mesmo método. A interação entre variáveis será expressa em valores de odds ratio com respectivos IC a 95
Assessment of difficulties in removing intrauterine devices (IUDs) and self-removal of IUDs in women using hormonal and non-hormonal devices
No full textIntroduction: Family planning programs aim to provide access
to contraceptives, preventing unplanned pregnancies. However, the rate of unplanned pregnancies remains very high in Brazil and worldwide. There is, therefore, a need to understand the barriers to contraceptive use, removals, and
related behaviors. The difficulty in removing an intrauterine device (IUD) can be a barrier to the use of this contraceptive method. However, there is little
literature on the ease and difficulties of removing intrauterine devices
(IUDs) and the practice of self-removal of IUDs.
Objectives: To evaluate the difficulty and factors related to IUD removal, acceptance,
and performance of users in the practice of self-removal of the device
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
