Two Great Intricate Gestational Syndromes. New Screening and Treatment Strategies
2020
Abstract Gestational hypertension and premature birth frequently and independently affect the pregnancy prognosis with potentially detrimental influence of the pregnancy evolution. Pregnancy-induced hypertension, spectrum and categories of the systemic disease: gestational hypertension, preeclampsia, eclamsia, Hellp syndrome, overlapping preeclampsia (PE) chronic arterial hypertension, are some of the complications that can occur over the pregnancy evolution. Annually, preeclampsia affects approximately 4 million pregnancies. According to ACOG, preeclampsia complicates the evolution of pregnancies in a 2-8% ratio. According to WHO and FIGO, premature birth occurs after 37 weeks of complete …
Le défaut de soutien familial dans l’immédiat post-partum : quels impacts sur l’émergence de la détresse maternelle ?
2018
Resume But de l’etude Cette etude vise a evaluer l’impact du defaut de soutien familial dans l’immediat post-partum sur l’etat psychique maternelle et de son evolution 6 mois apres la naissance de l’enfant. Patients et methode Trente-cinq meres primipares, vivant maritalement, ayant beneficie des services d’hospitalisation a domicile (HAD) via leur maternite. Apres leur inclusion, elles ont ete reparties a posteriori en deux groupes, en fonction de la variable independante : soutien familial, obtenue via une utilisation libre du Social Support Questionnaire (SSQ6) de Sarason (1983 ; 1987), rempli par les participantes. La detresse maternelle a ete evaluee sur 4 temps de mesure (T1–2 semaine…
Cytoplasmic incompatibility between Old and New World populations of a tramp ant
2020
Reproductive manipulation by endosymbiotic Wolbachia can cause unequal inheritance, allowing the manipulator to spread and potentially impacting evolutionary dynamics in infected hosts. Tramp and invasive species are excellent models to study the dynamics of host-Wolbachia associations because introduced populations often diverge in their microbiomes after colonizing new habitats, resulting in infection polymorphisms between native and introduced populations. Ants are the most abundant group of insects on earth, and numerous ant species are classified as highly invasive. However, little is known about the role of Wolbachia in these ecologically dominant insects. Here, we provide the first d…
Computer-assisted sperm analysis and reproductive science; a gift for understanding gamete biology from multidisciplinary perspectives
2018
The science of reproductive biology has been a source of fascination for centuries and has been marked both by important landmarks of discovery and influential, but persistent, errors of fact. The first century physician and philosopher, Galen of Pergamum, carried out empirical investigations on both humans and animals and proposed that conception required a combination of both male and female ‘principles’…
Implantation failure of endometrial origin: what is new?
2018
To review recent findings related to possible causes of recurrent implantation failure of endometrial origin in normal uterus.Recent evidences suggest that in apparently normal endometria, RIF may associate with molecular and functional changes in the uterus such as abnormal endometrial microbiota, including the presence of chronic endometritis, poor synchronization between the blastocyst and endometrium, and/or excessive uterine peristalsis. An altered endometrial microbiota detected by molecular techniques has been recently related to poorer embryo implantation, even in apparently normal endometria. The use of the endometrial receptivity analysis test to obtain an objective signature of e…
Endometrial Receptivity Analysis (ERA): data versus opinions
2021
Abstract This article summarises and contextualises the accumulated basic and clinical data on the ERA test and addresses specific comments and opinions presented by the opponent as part of an invited debate. Progress in medicine depends on new technologies and concepts that translate to practice to solve long-standing problems. In a key example, combining RNA sequencing data (transcriptomics) with artificial intelligence (AI) led to a clinical revolution in personalising disease diagnosis and fostered the concept of precision medicine. The reproductive field is no exception. Translation of endometrial transcriptomics to the clinic yielded an objective definition of the limited time period …
Exposure to a Highly Caloric Palatable Diet During Pregestational and Gestational Periods Affects Hypothalamic and Hippocampal Endocannabinoid Levels…
2016
Journal Article; Exposure to unbalanced diets during pre-gestational and gestational periods may result in long-term alterations in metabolism and behavior. The contribution of the endocannabinoid system to these long-term adaptive responses is unknown. In the present study, we investigated the impact of female rat exposure to a hypercaloric-hypoproteic palatable diet during pre-gestational, gestational and lactational periods on the development of male offspring. In addition, the hypothalamic and hippocampal endocannabinoid contents at birth and the behavioral performance in adulthood were investigated. Exposure to a palatable diet resulted in low weight offspring who exhibited low hypotha…
Mitochondrial dynamics and metabolism in induced pluripotency.
2020
Somatic cells can be reprogrammed to pluripotency by either ectopic expression of defined factors or exposure to chemical cocktails. During reprogramming, somatic cells undergo dramatic changes in a wide range of cellular processes, such as metabolism, mitochondrial morphology and function, cell signaling pathways or immortalization. Regulation of these processes during cell reprograming lead to the acquisition of a pluripotent state, which enables indefinite propagation by symmetrical self-renewal without losing the ability of reprogrammed cells to differentiate into all cell types of the adult. In this review, recent data from different laboratories showing how these processes are control…
Type of chromosome abnormality affects embryo morphology dynamics.
2016
Objective To study the differences in the cleavage time between types of embryo chromosomal abnormalities and elaborate algorithm to exclude aneuploid embryos according to the likelihood to be euploid. Design Retrospective cohort study. Setting University affiliated private center. Patient(s) Preimplantational genetic screening patients (n = 112) including cases of advanced maternal age, repeated implantation failure, and recurrent miscarriage. A total of 485 embryos were analyzed. Intervention(s) None. Main Outcome Measure(s) All biopsied embryos were cultured in an incubator with time-lapse technology, cleavage timing from insemination to day 3 and all kinetic parameters that have been de…
Effect of oocyte morphology on post-warming survival and embryo development in vitrified autologous oocytes.
2019
Abstract Research question Does the presence of dysmorphisms affect post-warming survival and embryo development in vitrified autologous oocytes? Design A retrospective study comparing post-warming survival, fertilization and embryo development between morphologically normal (n = 269) and dysmorphic oocytes (n = 147). Results The survival rate was 81.4% in the morphologically normal oocytes and 87.1% in the dysmorphic oocyte group (OR 1.53; 95% CI 0.86 to 2.72). The fertilization rate was 69.9 versus 66.4% (OR 0.85; 95% CI 0.53 to 1.36), the proportion of good-quality embryos on day 3 was 30.3% versus 32.0% (OR 1.08; 95% CI 0.59 to 1.97) and the blastocyst formation rate was 54.5% versus 60…
