Cesarean myomectomy and possible risk factors for admission to intensive care unit-a retrospective study
No full textObjectives: Cesarean myomectomy (CM) allows to remove fibroids and to restore uterine anatomy during delivery, combining two operations in one. It was opposed in the past due to surgical risks, although many reports showed that CM was not associated with increased morbidity. The risk for admission to an intensive care unit (ICU) following CM-as an objective indicator of maternal morbidity, potentially resulting in greater morbidity for patients, increased length of hospital stay, and higher hospital costs-has been poorly evaluated in the literature. The aim of our investigation is to estimate risk factors for ICU admission after CM. Material and methods: The patients were subdivided into two groups: 57 women who were postoperatively admitted to the ICU (study group), and 45 women not treated in the ICU (control group). The p-value of <0.05 was considered as statistically significant. Results: Data showed no statistically significant differences with regard to demographic factors, comorbidity and indications for cesarean section, as well as experience of the surgeon, number of hysterotomies, and incidence of emergency CS between the two groups. The most common reason for admission to the ICU was intraoperative hemorrhage (61.40%). As for the surgical characteristics, the study group showed significant increase in the rates of intraoperative transfusion (p=0.000) and intraoperative hemorrhage (p=0.000), as well as prolongation of surgical time (p=0.002). Myoma type and size were also significantly different between the groups (p=0.003 and p=0.000, respectively). Conclusions: The most important factor contributing to ICU admission after CM is intraoperative hemorrhage in case of bigger myomas and prolonged surgeries

No full textCan trans resveratrol plus d-chiro-inositol and myo-inositol improve maternal metabolic profile in overweight pregnant patients?
Full text linkObjective. To investigate the effect of trans-resveratrol from Polygonum cuspidatum/magnesium hydroxide complex, trademark Revifast®, plus D-chiro-inositol (DCI) and Myo-inositol (MI) during spontaneous pregnancies in overweight patients in a pilot study. Study design. A one-year, prospective, randomized, doubleblinded, placebo-controlled single center clinical study was carried out on overweight pregnant women. 110 patients were randomized in 3 groups to receive: Revifast® with DCI/MI (group I), DCI/MI alone (group II) or control group (group III) for 30 and 60 days. The main outcomes were to explore the lipid profile (total cholesterol, LDL, HDL, TG) and glucose levels, after 30 and 60 days of therapy. Results. No difference in systolic and diastolic parameters among 3 groups during study. All blood chemistry parameters improved compared to placebo at 30 days already, but significantly to 60 days, respect placebo. By comparing the two treatment groups, group I demonstrates significantly improved lipid and glucose parameters than group II, which are at 30 to 60 days of treatment. Conclusion. The supplementation of Trans-resveratrol, Revifast® in addition to DCI/MI in overweight pregnant woman with an elevated fasting glucose improves glucose levels, Total Cholesterol, LDL and TG
The Role of Surgeonsʼ Colposcopic Experience in Obtaining Adequate Samples by Large Loop Excision of the Transformation Zone in Women of Reproductive Age
No full textIntroduction: There is insufficient reporting on the level of colposcopic training for the safe use of large loop excision of the transformation zone. The aim of this study was to perform a quality assessment of large loop excision of the transformation zone in women of reproductive age by evaluating the surgeonsʼ colposcopic experience. Materials and Methods: A retrospective cohort studywas performed on diagnostic or therapeutic large loop excision of the transformation zone. The following variables were analyzed: age, parity, indications for surgery, level of surgeonʼs colposcopic experience, definitive histological diagnosis, margin involvement, and the presence and type of artifacts interfering with the pathological interpretation. Patients were divided into three groups: group A – 75 patients treated by junior colposcopists; group B – 74 patients treated by experienced colposcopists, and group C – 117 patients treated by expert colposcopists. Results: Regarding the presence and diagnostic significance of the artifacts the groups were significantly different. Inadequate samples were the least frequent in group C. Artifacts precluding histological diagnosis were the most common in group A. The margins were predominantly inconclusive in group A. Conclusions: A high rate of artifacts is a disadvantage of the large loop excision of the transformation zone performed by surgeons less skilled for colposcopy. Although large loop excision of the transformation zone is considered to be a minor surgery, skills in colposcopy ar e an essentialprerequisite for optimal results
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
