Compressive suture of the lower uterine segment for the treatment of postpartum hemorrhage due to complete placenta previa : a preliminary study
No full textAim: To assess the efficacy of a uterine compression suture technique in controlling hemorrhage after removal of complete placenta previa during cesarean section. Methods: This prospective study was performed in a tertiary referral hospital and included 18 patients with postpartum hemorrhage following removal of complete placenta previa during elective cesarean section. All 18 patients underwent bilateral anteroposterior compression suture of the lower uterine segment. All patients were followed postpartum for evaluation of uterine cavity and menstrual cycles. Results: Anteroposterior compressive suture of the lower uterine segment achieved immediate complete hemostasis in all 18 patients. No surgical complication was observed. All patients recovered normal menstrual cycles. Normal patency of the uterine cavity was documented with sonohysterography in all patients at the 6-month follow-up visit. Conclusions: This quick and simple suture technique seems to be effective in stopping hemorrhage following complete placenta previa removal during cesarean section. Normal patency of the uterine cavity seems not to be impaired at medium-term follow-up
Effect of soy-derived isoflavones on hot flashes, endometrial thickness, and the pulsatility index of the uterine and cerebral arteries
No full textThis study was conducted to identify clinical factors that are predictive of
treatment choice for pelvic organ prolapse. One hundred forty-six women diagnosed with
pelvic organ prolapse were educated about their condition and possible treatments before
being offered one of three different treatment choices: expectant management (any choice
other than pessary or surgery, including pelvic muscle exercises), pessary, or surgery
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
Effect of soy-derived isoflavones on hot flushes, endometrial thickness, and the pulsatility index of the uterine and celebral arteries
No full textEFFECTS OF SOY-DERIVED ISOFLAVONES ON HOT FLUSHES AND VASCULAR REACTIVITY
No full textObjectives: The aim of this study was to investigate the effects of soy-derived isoflavones on hot flushes and vascular reactivity of Uterine Arteries (UA), Internal Carotid Arteries (ICA), Middle Cerebral Arteries (MCA), in post- menopausal women.
Materials and methods: This study was a double-blind placebo-controlled randomised trial. 58 postmenopausal Italian women aged between 45 and 60 years entered the study. They all were free from any major illness and com- plained of at least seven hot flushes daily. 28 of them were treated with two tablets daily containing 36mg of soy- derived isoflavones, each. The other 30 patients were treated with two placebo tablets daily. All patients kept a daily diary of hot flushes. Patients were evaluated at basal time, after three months and after six months. At each control time the number of hot flushes was recorded and an_ultrasound scan was performed together with a doppler evaluation of uter- ine and cerebral arteries.
Results: The daily mean number of hot flushes at basal time was 9.7 in both groups. After the first month we observed a significant decrease to 6.2 in the soy group and 5.6 in place- bo group. However, no differences were observed between the two groups. This reduction was maintained for both groups till the end of the study.
Conclusions: The treatment with soy-derived isoflavones causes a reduction of hot flushes not different from that due to placebo
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
