perinatal outcomes after stimulated

BACKGROUND: The diagnostic criteria and phenotypes in polycystic ovary syndrome are heterogeneous. Currently, it is unclear how to assess a patient's prognosis based on the onset time of menstruation disturbance. Evidence on this topic is scarce and has mainly focused on menstrual patterns. OBJECTIVE: This study aimed to assess the association between the onset time of menstrual disturbance and clinical features and in vitro fertilization pregnancy outcomes in patients with polycystic ovary syndrome...

BACKGROUND: Emerging evidence supporting the use of valaciclovir to reduce fetal infection after maternal primary cytomegalovirus (CMV) infection has stimulated interest in routine CMV serological screening in pregnancy. It is important to understand the healthcare consumer perspective of a CMV infection during pregnancy to minimize unintended harms of screening. METHODS: We conducted a qualitative study using semi-structured interviews with Australian women who had a lived experience of CMV infection following serological testing during pregnancy...

STUDY QUESTION: Which clinical and embryological factors should be considered to apply double embryo transfer (DET) instead of elective single embryo transfer (eSET)? SUMMARY ANSWER: No clinical or embryological factor per se justifies a recommendation of DET instead of eSET in IVF/ICSI. WHAT IS KNOWN ALREADY: DET is correlated with a higher rate of multiple pregnancy, leading to a subsequent increase in complications for both mother and babies...

BACKGROUND: Induction of labor in women with unfavorable cervix can be started with cervical ripening by dinoprostone vaginal insert. In cases of unsuccessful response, management is unclear: a possible option is a repeated induction with prostaglandins. The aim of this study was to assess the results of a second induction by either dinoprostone or misoprostol, comparing those treatments. METHODS: A retrospective analysis was carried out on a cohort of 109 women with unsuccesful response to a first attempt of induction with dinoprostone vaginal insert, who required a second stimulation by either dinoprostone vaginal gel (56 patients) or oral misoprostol (53 patients)...

BACKGROUND: After the transfusion of RhD-positive red blood cell (RBC)-containing products to an RhD-negative woman of childbearing potential (WCP) during trauma resuscitation, there are several events that must occur for that WCP to have a future pregnancy affected by hemolytic disease of the fetus and newborn (HDFN). This study identified and quantitated the frequency of a novel event in the sequence from RhD-positive transfusion during trauma resuscitation to an HDFN outcome, that is, the development of a high titer anti-D among women who were D-alloimmunized...

OBJECTIVE: To assess pre-term birth, low birth-weight and growth restriction according to maternal thyroid screening results and subsequent treatment. METHODS: This is a nonintervention nested case-control study derived from 10,052 asymptomatic women previously screened during the first trimester marker with anti-thyroid peroxidase antibodies, serum thyroid stimulating hormone, and free thyroxine. Screening results had been classified as positive with one or more markers outside the normal range and referred to an endocrinologist...

OBJECTIVE: To outline oocyte competence after progestin primed ovarian stimulation with Norethisterone acetate (NETA-PPOS) compared to conventional GnRH-antagonist protocol. STUDY DESIGN: Retrospective matched case-control study involving advanced-maternal-age women undergoing ICSI with PGT-A. 89 NETA-PPOS were matched with 178 control patients based on maternal age and ovarian reserve biomarkers. Both groups underwent recombinant-FSH OS with GnRH-agonist ovulation trigger and collected ≥1 MII...

A large number of randomized controlled trials (RCTs) have been published on the effects of oral/vaginal misoprostol and oxytocin on delivery outcomes; however, data from these RCTs are conflicting. Although some meta-analyses summarized available findings in this regard, several eligible RCTs have been published since the release of those meta-analyses. Therefore, the current updated systematic review and meta-analysis of RCTs was conducted to compare the effects of oral/vaginal misoprostol and oxytocin on delivery and neonatal outcomes...

PURPOSE: To evaluate the obstetric and perinatal outcomes of three routine endometrial preparation protocols in women with PCOS who underwent frozen embryo transfer (FET). METHODS: This was a retrospective study in women with PCOS who underwent FET in an academic reproductive medical center. A total of 2710 cycles were enrolled and classified into three groups according to different endometrial preparation protocols; human menopausal gonadotropin (HMG), letrozole + HMG, or hormone replacement therapy (HRT)...

CONTEXT: Cerebral visual impairment (CVI) is an overarching term, defined as a brain-based visual impairment with onset in childhood, unexplained by an ocular disorder and associated with unique visual and behavioral characteristics. Good vision and awareness of visual function in a child are highly essential as neuroplasticity is maximum in the first three years of life and response to intervention is utmost in this period. Awareness is lacking regarding CVI, and the diagnosis is largely missed...

Frozen-thawed embryo transfer (FET) has been a viable alternative to fresh embryo transfer in recent years because of the improvement in vitrification methods. Laboratory-based studies indicate that complex molecular and morphological changes in endometrium during the window of implantation after exogenous hormones with controlled ovarian stimulation may alter the interaction between the embryo and endometrium, leading to a decreased implantation potential. Based on the results obtained from randomized controlled studies, increased pregnancy rates and better perinatal outcomes have been reported following FET...

INTRODUCTION: Hormone replacement treatment (HRT) is the most commonly used endometrial preparation protocol for frozen embryo transfer (FET) in patients with polycystic ovary syndrome (PCOS). However, studies have found that HRT may increase the risk of hypertensive disorders of pregnancy and some obstetric complications. Letrozole is a new first-line ovulation induction drug for PCOS and can effectively induce spontaneous ovulation by reducing oestrogen levels. However, letrozole is still rarely used in FET and has only been reported in a few studies in Asian populations...

Objective: To investigate the effect of preimplantation genetic testing for aneuploidies (PGT-A) on pregnancy outcome and perinatal outcome of single live birth in patients with unexplained recurrent spontaneous abortion (URSA). Methods: The clinical data of 351 cycles of the first transfer of a blastocyst through whole embryo freezing in the Reproductive Center of the Third Affiliated Hospital of Zhengzhou University from 2019 to 2021 were retrospectively analyzed. According to whether PGT-A was performed before the transfer, the patients were divided into two groups: the PGT-A group (160 cycles) and the control group (191 cycles) were treated with in vitro fertilization/intracytoplasmic sperm microinjection (IVF/ICSI)...

After large neocortical lesions, such as hemidecortication, children can show significant motor and cognitive impairments. It thus is of considerable interest to identify treatments that might enhance long-term functional outcome. We have previously shown that tactile stimulation enhances recovery from perinatal focal cortical lesions in rats, so the goal of the present experiment was to explore the effectiveness of postlesion tactile stimulation in reducing functional deficits associated with neonatal hemidecortication...

BACKGROUND: There is ongoing interest in glucocorticoid treatment during oocyte stimulation to treat infertility in women who have undergone Assisted Reproductive Technology (ART). OBJECTIVE: This meta-analysis was performed to evaluate the efficiency and safety of adjuvant glucocorticoid therapy on pregnancy outcomes in infertile women undergoing ART cycles. STUDY DESIGN: A literature search was performed in PubMed, EMBASE, Web of Science, and the Cochrane Library up to December 2022...

BACKGROUND: We developed a simplified IVF culture system (SCS) which has proven to be effective and safe in a selected IVF cohort. METHODS: Preterm birth (PTB) and low birth weight (LBW) of 175 singletons born after using the SCS, 104 after fresh embryo transfer (ET), and 71 after frozen embryo transfer, were compared with all singletons born in Flanders between 2012 and 2020 conceived after natural conception, ovarian stimulation (OS), and assisted reproduction (IVF/ICSI)...

PURPOSE OF REVIEW: This review focuses on the efficacy of letrozole stimulated frozen-thawed embryo transfer (FET) compared to hormone replacement therapy (HRT) FET in women with polycystic ovarian syndrome (PCOS) and/or oligo-anovulation. Further, obstetric and perinatal risks in HRT FET are summarized. RECENT FINDINGS: The presence of a corpus luteum seems to reduce the risk of pregnancy-related hypertension and preeclampsia after FET. As a natural cycle (NC) FET is not an option for women with oligo-/amenorrhea these women may benefit from FET with mild stimulation compared to HRT FET...

STUDY QUESTION: How does an altered maternal hormonal environment, such as that seen during superovulation with gonadotropins in ART, impact human uterine immune cell distribution and function during the window of implantation? SUMMARY ANSWER: Hormonal stimulation with gonadotropins alters abundance of maternal immune cells including uterine natural killer (uNK) cells and reduces uNK cell ability to promote extravillous trophoblast (EVT) invasion. WHAT IS KNOWN ALREADY: An altered maternal hormonal environment, seen following ART, can lead to increased risk for adverse perinatal outcomes associated with disordered placentation...

The aim of the study is to compare the perinatal outcomes of twin pregnancies resulting from assisted reproductive technology (ART) treatment in which granulocyte colony-stimulating factor (G-CSF) was used with those in which it was not. In this retrospective study, the clinical data of 122 dichorionic diamniotic twin pregnancies were reviewed. Pregnancies were divided into two groups, G-CSF-treated and non-G-CSF treated. Maternal age, gestational week at birth, oligohydramnios, gestational hypertension, pre-eclampsia, preterm birth, first-trimester bleeding, gestational diabetes, rupture of membrane, foetal congenital anomalies, admission to the neonatal intensive care unit, birth weight (BW), small for gestational age, BW discordance, Apgar score and placental weight were compared between the groups...

Vagus nerve stimulation (VNS) is one of the treatment options for drug-resistant epilepsy (DRE). To analyze the efficacy of VNS in children of DRE with structural etiology, we conducted a cohort study including 95 patients of DRE with structural etiology who underwent VNS treatment. Patients were followed up every 3 months at the outpatient department or via a remote programming platform. The median follow-up period was 2.6 years (range 1.0-4.6 years). The respective responder rates at 6, 12, 18, and 24 months of follow-up were 40...
