HPV vaccines: State of the art
Cervical cancer is one of the most common types of cancer in women worldwide and is frequent in relatively young women. In the last decades, its incidence has decreased following the implementation of screening programs, mainly in developed countries. Cervical screening programs, while successful if properly carried out, are difficult and expensive to implement, especially in developing countries. Advances in the understanding of the role of human papillomavirus (HPV) in the etiology of high-grade cervical lesions and cervical cancer have led to the development and evaluation of two prophylactic HPV vaccines. Vaccination against the HPV, which is the major cause of cervical cancer, is a significant step forward. This review article provides a summary of the most recent studies related with the development and efficacy of the two HPV vaccines
New players in ovarian cancer.
Ovarian cancer is the leading cause of gynecologic cancer mortality worldwide. The aim of this review is to highlight the most recent studies regarding ovarian cancer pathogenesis and the new therapeutic approaches against this insidious disease. We focus on the relevance of some cell cycle genes, transcription factors, and microRNAs in the carcinogenesis of ovarian cancer as well as on a new hypothesis for therapy using histone deacetylase inhibitors. We also report recent studies regarding some mechanisms of chemoresistance, a major obstacle in the treatment of ovarian cancer. Together these studies can improve our knowledge of ovarian cancer tumorigenesis and diagnosis providing new tools to hopefully defeat this deadly disease
New insights in endometrial carcinogenesis
Endometrial carcinoma is the most common cancer of the female genital tract in Europe and in the United States. Despite advances in defining the biology of endometrial carcinomas, there has been poor progress in determining markers that distinguish preinvasive endometrial proliferations. The aim of this review is to highlight the most recent studies regarding the molecular markers involved in endometrial adenocarcinoma pathogenesis and carcinogenesis. We focus on studies that describe markers with potential to progress from endometrial hyperplasia to invasive disease
Cell cycle genes in ovarian cancer: steps toward earlier diagnosis and novel therapies
Human malignant tumors are characterized by abnormal proliferation resulting from alterations in cell cycle-regulatory mechanisms. The regulatory pathways controlling cell cycle phases include several oncogenes and tumor suppressor genes that display a range of abnormalities with potential usefulness as markers of evolution or treatment response in ovarian cancer. This review summarizes the current knowledge about these aberrations in malignant tumors of the ovary. We sought to divide cell cycle-regulatory genes into four subgroups on the basis of their predominant role in a specific phase or during the transition between two phases of the cell cycle
Multidisciplinary International Conference on Gynecologic Cancer, Bologna, Italy, June 8-12, 2005
The first "Multidisciplinary International Conference on Gynecologic Cancer" which was held in Bologna on June 8-12, 2005, addressed some of the most crucial topics in gynecologic oncology, presented the latest achievements and, at the same time, designed the guidelines for future developments in the field. The scientific program was intended not only to share and compare views and ideas among gynecologists but also with oncologists and researchers in basic science. The scientific committee strongly believed in the "multidisciplinary approach" towards medicine and particularly towards patients
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
Cervical cancer in pregnancy: Analysis of the literature and innovative approaches
Cervical cancer is one of the most common gynecological malignancies diagnosed during pregnancy although, fortunately, it is a rare event. In majority of cases, the management of cervical cancer in pregnant women is not different from nonpregnant women and prognosis seems not compromised by pregnancy. The association between cancer and pregnancy appears to be a significant challenge for women and specialists and the decisions about therapy must be individualized and taken by a multidisciplinary team. This review is focused on cervical cancer in pregnancy. The aim is to discuss the diagnosis, potential biomarkers and molecular aspects, therapeutic approaches, and prognosis from intraepithelial cervical neoplasia to invasive cervical cancer (early and advanced stages) in different gestational ages. We provide an overview of the current literature regarding the treatment strategies of concurrent pregnancy and cervical cancer cases and we propose some clinical advices to help clinicians to manage this condition. A mention about the effects of the conservative therapy (as conization) on fertility, the human papillomavirus vaccine in pregnant women and our center's experience with obstetrical and oncological outcomes are reported
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
