Wiedemann-Steiner syndrome as a major cause of syndromic intellectual disability: A study of 33 French cases.

2018

International audience; Wiedemann-Steiner syndrome (WSS) is a rare syndromic condition in which intellectual disability (ID) is associated with hypertrichosis cubiti, short stature, and characteristic facies. Following the identification of the causative gene (KMT2A) in 2012, only 31 cases of WSS have been described precisely in the literature. We report on 33 French individuals with a KMT2A mutation confirmed by targeted gene sequencing, high-throughput sequencing or exome sequencing. Patients' molecular and clinical features were recorded and compared with the literature data. On the molecular level, we found 29 novel mutations. We observed autosomal dominant transmission of WSS in 3 fami…

Coupling News Sentiment with Web Browsing Data Improves Prediction of Intra-Day Price Dynamics

2015

The new digital revolution of big data is deeply changing our capability of understanding society and forecasting the outcome of many social and economic systems. Unfortunately, information can be very heterogeneous in the importance, relevance, and surprise it conveys, affecting severely the predictive power of semantic and statistical methods. Here we show that the aggregation of web users' behavior can be elicited to overcome this problem in a hard to predict complex system, namely the financial market. Specifically, our in-sample analysis shows that the combined use of sentiment analysis of news and browsing activity of users of Yahoo! Finance greatly helps forecasting intra-day and dai…

Endoscopic near infrared and indocyanine green to verify the viability of the subcutaneous flap for vulvar cancer.

2019

Abstract Introduction Vulvar cancer often requires radical vulvectomy with subsequent vulvar flap. Approximately in 20–60% of cases, there are post-operative complications ranging from infection to flap necrosis that often require reoperation. Several methods have been described to verify the vitality of the flap, but these are often expensive and require specific machinery that is not generally present in a gynecological clinic. In this case report, we present a viability verification of V Y fasciocutaneous advancement flap for vulvar reconstruction by Endoscopic Near-Infrared and Indocyanine Green. Methodology The patient was a 67-year-old woman with FIGO IB ≤ 4 cm squamous cell vulvar ca…

Uterine disorders affecting female fertility: what are the molecular functions altered in endometrium?

2020

[EN]: Objective:To determine the molecular functions of genes exhibiting altered expression in the endometrium of women with uterine disorders affecting fertility. Design: Retrospective analysis integrating case and control data from multiple cohorts with endometrium gene expression in women with uterine disorders. Setting: Infertility research department affiliated with a university hospital. Patient(s): Two hundred and forty women, 121 of whom were controls, 119 of whom had endometrial adenocarcinoma (ADC), recurrent implantation failure (RIF), recurrent pregnancy loss (RPL), or stage II–IV endometriosis. Intervention(s): None. Main Outcome Measure(s): Genomewide gene expression and alter…

SARS-CoV-2 infection risk assessment in the endometrium: viral infection-related gene expression across the menstrual cycle

2020

Objective To determine the susceptibility of the endometrium to infection by—and thereby potential damage from—SARS-CoV-2. Design Analysis of SARS-Cov-2 infection-related gene expression from endometrial transcriptomic data sets. Setting Infertility research department affiliated with a public hospital. Patient(s) Gene expression data from five studies in 112 patients with normal endometrium collected throughout the menstrual cycle. Intervention(s) None. Main Outcome Measure(s) Gene expression and correlation between viral infectivity genes and age throughout the menstrual cycle. Result(s) Gene expression was high for TMPRSS4, CTSL, CTSB, FURIN, MX1, and BSG; medium for TMPRSS2; and low for…

Relevance of assessing the uterine microbiota in infertility

2018

Technical advances in massive parallel sequencing have allowed the characterization of the whole reproductive tract microbiome in all the compartments beyond the vagina. The microbiota in the uterine cavity seem to be a continuum from the microbiota in the vagina, but several works have reported significant differences between vaginal and endometrial microbiota, highlighting the relevance of assessing the upper genital tract microbiota to better understand the potential roles of bacteria in the physiological and pathological processes taking place in the uterine cavity, including embryo implantation, pregnancy maintenance, and other gynecological diseases. However, the study of the endometr…

Sperm chromosomal abnormalities and their contribution to human embryo aneuploidy.

2018

In this work we reviewed 18 years of experience using fluorescence in situ hybridization (FISH) for sperm aneuploidy testing. We evaluated parameters associated with increased numerical sperm chromosome abnormalities and determined the male contribution to embryo aneploidies in terms of reproductive outcome by increased sperm aneuploidy. This retrospective study analyzed data from 2008 sperm samples of infertile males undergoing FISH analysis because of clinical history of repetitive implantation failure, recurrent miscarriage, impaired sperm parameters, or mixed causes. Sperm concentration was the only sperm parameter associated with FISH results—we observed a gradual increase of abnormal …

Paving the way for a gold standard of care for infertility treatment: improving outcomes through standardization of laboratory procedures.

2016

Infertility affects over 70 million couples globally. Access to, and interest in, assisted reproductive technologies is growing worldwide, with more couples seeking medical intervention to conceive, in particular by IVF. Despite numerous advances in IVF techniques since its first success in 1978, almost half of the patients treated remain childless. The multifactorial nature of IVF treatment means that success is dependent on many variables. Therefore, it is important to examine how each variable can be optimized to achieve the best possible outcomes for patients. The current approach to IVF is fragmented, with various protocols in use. A systematic approach to establishing optimum best pra…

Machine Learning-Based Approach Highlights the Use of a Genomic Variant Profile for Precision Medicine in Ovarian Failure

2021

Ovarian failure (OF) is a common cause of infertility usually diagnosed as idiopathic, with genetic causes accounting for 10–25% of cases. Whole-exome sequencing (WES) may enable identifying contributing genes and variant profiles to stratify the population into subtypes of OF. This study sought to identify a blood-based gene variant profile using accumulation of rare variants to promote precision medicine in fertility preservation programs. A case–control (n = 118, n = 32, respectively) WES study was performed in which only non-synonymous rare variants &lt
