Analysis of the degree to which the recommendations of experts in hysteroscopy can be adopted
No full textThe Guidelines are an useful tool in clinical practice. However, they have one weak point: their acceptability A “Guideline” is HELPFUL when applied, and is applied when it provides handy and shared information. It must involve the contribution of the experience, made of specific language and common sense, of a representative group of professionals. In order to evaluate partially overcome these limits and evaluate the acceptability of recommendations in hysteroscopy, a meeting was held in Milan. This paper presents the outcome of that meeting
Determinants of the economic burden of ART on the Italian NHS: insights from the Lombardy region
Full text linkAbstract With the rising spread of Assisted Reproductive Technology (ART), it becomes imperative to understand the determinants of resource utilization in ART versus spontaneous pregnancies to enhance policies directed to pregnancy care. The focus of our study is to examine the costs associated with ART from the perspective of the Italian NHS and to investigate in depth the contributing social and clinical factors. Using the healthcare informative system of Lombardy, a Region of Northern Italy, we gathered individual-level information for a cohort of women who experienced either spontaneous pregnancies or pregnancies following ART from 2007 until 2020. The information covered multiple healthcare services, and we used a propensity score matching technique to match couples of ART/No ART women based on a comprehensive set of confounders. We then applied statistical tests and regression models to identify the impact of ART on the reported cost differences. Our cohort was composed of 44652 women and results revealed significantly higher costs for ART pregnancies, especially in terms of hospital admissions (additional 1611€, 95% CI 1558-1666) and drug prescriptions (additional 216 €, CI 95% 204-228) occurring before delivery. In-depth analysis showed for ART pregnancies, i) a higher likelihood of incurring expenses related to complications and ii) higher costs associated with two established clinical practices that lack scientific evidence supporting their efficacy. Our study sheds light on the complex interplay of clinical and social factors influencing the ART burden, emphasizing the importance of tailored support and evidence-based practices in optimizing outcomes and resource allocation
Risk factors for non-adherent retained placenta after vaginal delivery: a systematic review
No full textBackground Retained placenta represents a cause of maternal morbidity and mortality affecting 0.5-3% of all vaginal deliveries. The unpredictability of this condition makes difficult to develop predictive and preventive strategies to apply in clinical practice. This analysis collected and analyzed all known risk factors related to this obstetric complication. Methods A systematic literature review for all original research articles published between 1990 and 2020 was performed. Observational studies about retained placenta risk factors published in English language were considered eligible. Conference abstracts, untraceable articles and studies focused on morbidly adherent placenta were excluded. The included articles were screened to identify study design, number of enrolled patients and retained placenta risk factors investigated. All stages of the revision followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement. Results Thirty-five studies met the inclusion criteria. The reported retained placenta prevalence ranged from 0.5 to 4.8%. Maternal age, previous cesarean sections, previous dilation and curettage, previous retained placenta, labor induction, resulted as the most recurrent, independent risk factors for retained placenta. Previous estro-progestins therapy, morphological placental features (weight, shape, insertion of umbilical cord, implantation site), endometriosis, Assisted Reproductive Technologies, Apgar score are fascinating new proposal risk factors. Conclusions Old and new data are not enough robust to draw firm conclusions. Prospective and well-designed studies, based on a well agreed internationally retained placenta definition, are needed in order to clarify this potential dramatic and life-threatening condition
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
Histological Features of Neovaginal Epithelium after Vaginoplasty in Mayer-Rokitansky-Küster-Hauser Syndrome
No full textObjective To analyze the features of the epithelia coating neovaginas after vaginoplasty in women affected by Mayer-Rokitansky-Küster-Hauser syndrome Study Design We conducted a retrospective analysis of prospectively collected data. Women affected by Rokitansky syndrome who underwent neovaginal biopsy after vaginoplasty (McIndoe surgery, intestinal vaginoplasty, Vecchietti surgery, and Davydov surgery) were included. Macroscopic mucosal features were assessed through clinical examination and the Schilling test. Each biopsy specimen was prepared for examination by light microscopy and in some cases by scanning electron microscopy (SEM). Results Thirty-six patients (4 McIndoe, 2 intestinal vaginoplasty, 14 Vecchietti, and 16 Davydov) were included. All biopsies were performed without complications. In McIndoe's neovaginas, the mucosal microscopic features were similar to normal skin, with large areas of preserved epithelium, heterogeneous presence of dermal papillae, and superficial keratinization. The characteristics of the intestinal neovagina's surface were similar to those of a sigmoid colon, with well-shaped glands, cylindrical cells, and a secreting mucosa. In Vecchietti neovaginas, the surface the epithelium was flat and multilayered, highly similar to that of a normal vagina, with the presence of glycogen and superficial desquamation. On medium SEM magnification evaluation, the epithelium presented flattened polygonal cells. Finally, in Davydov neovaginas, none of the specimens had persistent mesothelial elements. The squamous neo-epithelium had regular aspects of differentiation with the presence of glycogen. At greater SEM magnification, microridges were evident, with a regular distribution. Conclusion Each different technique of vaginoplasty leads to unique histological and structural features of the neovagina's mucosa. Knowledge of these elements must be the basis for the choice of the most appropriate intervention

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
