Identification of patients with high osteoporosis risk: Analysis of FRAX and phalangeal ultrasonography in a female population in North-East Italy
Aim. Osteoporosis is a worldwide health problem and bone fractures from osteoporosis are among the major causes of disability, with a great impact on the national health budgets. The aim of our study was to analyze the efficacy of FRAX algorithm and phalan-ger ultrasound to predict the risk of osteoporotic fractures, in order to identify a high risk population to examine with a second level diagnostic analysis. Methods. The study population was composed of 1208 premenopausal, perimenopausal, and postmenopausal women, between 40 and 81 years. For each woman phalangeal QUS was performed and FRAX index was calculated. The FRAX index was evaluated according to standard plots available on web (http://www. shed.ac.UK/FRAX/index.htm). Results. Analysing the correlation between women age and phalanger bone ultrasound values we know that all parameter decrease with increasing of age. We found a significant difference between FRAX index and the ultrasound parameters (P<0.05) to predict a major osteoporotic fracture, we did not find differences between age and ultrasound parameters. Furthermore, we show that after correction per age of the women the ultrasound parameters lose their significant correlation with major osteoporotic fractures. Finally, FRAX index showed a good AUC and in our population and a 10-year probability over 9-4% of major osteoporotic fractures had a good specificity (88%) and sensitivity (83%) to predict osteoporotic fractures. Conclusion. Our data suggest that FRAX in-dex alone could be used to address high risk women to more invasive tests but we need more data about ultrasound parameters.Funding.-This study was supported by grants from Tavagnacco municipality, Udine, Italy
Female stress incontinence and transobturator tape: outcomes and quality of life
TransObturatorTape (TOT) is a surgical technique for the correction of stress urinary incontinence
(SUI). We report our experience about clinical outcomes and quality of life of patients who underwent
TOT. We collected clinical and instrumental data about 27 patients who underwent TOT during 2006-
2007, and investigated their quality of life using the King’s Health Questionnaire (KHQ). We analysed
data by R (version2.7.0), considering significant p<0.05.Mean age at surgery was 62.81years (range 39-
83), mean BMI was 29.31kg/mq (±7.74). 85.19% of patients were in menopause (73.91% spontaneous).
Mean parity was 2.19 (±1.11) and only two women were nulliparous. 44.44% of patients had at least one
previous gynaecological intervention (34.62% hysterectomy). Relapse prevalence was 44.44%,
correlated with higher (worse) KHQ scores (p<0.05), and affected especially women with a mixed
urinary incontinence (MUI) (p0.09) or with a coexistent genital prolapse (p<0.05). TOT improved women
quality of life, independently by relapse or by the presence of a MUI (p<0.05). Previous gynaecological
interventions, and in particular hysterectomy followed by SUI, resulted protective against symptom
relapse.TOT does not resolve urge component in case of MUI and may cause urge incontinence after
SUI correction. Anyway, women quality of life results strongly improved by TOT, even in case of
relapse
Prediction of large-for-gestation neonates with first-trimester maternal serum PAPP-A.
OBJECTIVE:
To identify maternal/pregnancy characteristics, first trimester ultrasound parameters and biochemical indices which are significant independent predictors of large-for-gestational age (LGA)neonates. DESIGN:Observational crosssectional study.
SETTING:
Fetal Medicine Unit, Department of Obstetrics and Gynecology, University of Udine.
POPULATION:
72 singleton pregnancies presenting for screening for chromosomal abnormalities by nuchal translucency and maternal serum biochemistry at 11-14 weeks.
METHODS:
Linear regression was applied to develop first trimester prediction models for LGA.
RESULTS:
Maternal height, parity, smoking, assisted conception and pregnancy-associated plasma protein-A were significant independent predictors of LGA. PAPP-A cut-off value expressed in MoM of 1.25 used for the study was chosen to obtain good sensitivity and specificity values.
CONCLUSION:
Prediction for birthweight deviations (LGA) is feasible using data available at the routine 11-14 weeks' examination
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
