BACKGROUND: Intra-cytoplasmic sperm injection (ICSI) is used in assisted reproductive technology (ART) laboratories. However, there is no consensus regarding the precise time intervals within ICSI cycles [oocyte pick up (OPU), oocyte denudation (DN), and ICSI], and results are inconsistent and contradictory. Thus, we aim to evaluate whether there is a concordance regarding the time intervals used in different laboratories and a concrete time that gives better laboratory and reproductive results...

Hemolysis, elevated liver enzymes, and low platelet count (HELLP) syndrome is a life-threatening pregnancy complication. Though there are several medications widely used to treat HELLP syndrome, delivery is the only efficient treatment. The goal of the present study was to investigate the effects of platelet-derived growth factor-D (PDGF-D), a newly identified PDGF, in a rat model of HELLP syndrome which was accomplished by sFlt-1 and sEng injection. The expression levels of PDGF-D in pregnant women diagnosed with HELLP syndrome was determined...

The physiological role of calcitonin, and its receptor, the CTR, has long been debated. We previously provided the first evidence for a physiological role of the CTR to limit maternal bone loss during lactation in mice by a direct action on osteocytes to inhibit osteocytic osteolysis. We now extend these findings to show that CTR gene expression is upregulated 2-3 fold in whole bone of control mice at the end of pregnancy (E18) and lactation (P21) compared to virgin controls. This was associated with an increase in osteoclast activity evidenced by increases in osteoclast surface/bone surface and Dcstamp gene expression...

The association of pregnancy and Cushing's disease (CD) is rare. A 28-year-old woman was admitted for clinical suspicion of Cushing's syndrome. The investigations confirmed the diagnosis of CD with secondary hypogonadotropic hypogonadism due to an invasive pituitary macroadenoma. The patient underwent transsphenoidal adenomectomy, and histopathology showed an adrenocorticotropic hormone pituitary adenoma. Initial remission of CD ensued, and fertility was restored as the patient had 2 uncomplicated pregnancies...

BACKGROUND: The uterine cervix is a mechanical and immunological barrier against ascending infection during pregnancy. Cervical insufficiency (CI), a painless cervical dilation that occurs in the mid-trimester, is an important cause of extremely preterm birth. We hypothesized that women with CI have a differential transcriptomic profile. Therefore, we compared the transcriptomic profile of peripheral blood in women with CI and that of controls. METHODS: RNA sequencing was used to generate the global gene expression profiles of 11 women with CI and 4 controls, and differential expression analysis was performed to identify genes showing significant expression changes between the CI (n = 11) and control (n = 4) groups as well as between the CI-preterm (n = 7) and CI-term (n = 4) groups...

CONTEXT: Excess glucocorticoids impact fetal health. Maternal glucocorticoids peak in early morning. Fetoplacental 11β-hydroxysteroid dehydrogenase type 2 (11β-HSD2) inactivates cortisol to cortisone, protecting the fetus from high glucocorticoids. However, time-specific alterations of human fetoplacental 11β-HSD2 have not been studied. OBJECTIVE: We hypothesized that fetoplacental 11β-HSD2 activity shows time-specific alteration and acute affective or anxiety disorders impact fetoplacental 11β-HSD2 activity...

BACKGROUND: Thyroid dysfunction and gestational diabetes are the two most common endocrine disorders that can be observed during pregnancy. Thyroid function abnormalities could be associated with insulin resistance (IR) and changes in carbohydrate metabolism. In patients with type 1 diabetes, thyroid function is usually evaluated to rule out abnormalities within a second autoimmune disease. Patients with type 2 diabetes are tested for thyroid function in view of the associated weight gain, IR and changes in metabolism...

Studies indicate that pregnancy is associated with declines in working memory (WM), potentially due to intense pregnancy hormonal fluctuations. These declines extend into the postpartum period and may even be worsened due to sleepless nights and continued hormonal changes. However, previous studies finding WM stability from pregnancy to postpartum have not used a control group to examine practice effects on WM tests. The current study used a well-matched control group, fathers, to examine a) whether mothers and fathers differ on tests of WM during pregnancy and postpartum, and b) whether mothers show a postpartum WM decline, taking into account the practice effects of fathers...

BACKGROUND: Asthenozoospermia is one of the most common causes of male infertility, and its genetic etiology is poorly understood. DNAH9 is a core component of outer dynein arms in cilia and flagellum. It was reported that variants of DNAH9 (OMIM: 603330) might cause primary ciliary dyskinesia (PCD). However, variants in DNAH9 lead to nonsyndromic severe asthenozoospermia have yet to be reported. METHODS: Whole exome sequencing (WES) was performed for two individuals with nonsyndromic severe asthenozoospermia from two non-consanguineous families, and Sanger sequencing was performed to verify the identified variants and parental origins...

Early pregnancy is characterised by elevated circulating levels of vitamin D binding protein (DBP). The impact of this on maternal and fetal health is unclear but DBP is present in the placenta, and DBP gene variants have been linked to malplacentation disorders such as preeclampsia. A functional role for DBP in the placenta was investigated using trophoblastic JEG3, BeWo and HTR8 cells. All three cells lines showed intracellular DBP, with increased expression and nuclear localisation of DBP in cells treated with the active form of vitamin D, 1,25-dihydroxyvitamin D (1,25D)...

BACKGROUND: Non-invasive oocyte quality scoring, based on cumulus gene expression analysis, in combination with morphology scoring, can increase the clinical pregnancy (CPR) and live birth rates (LBR) in Day 3 eSET (elective single embryo transfer) ICSI patients. This was first investigated in a pilot study and is now confirmed in a large patient cohort of 633 patients. It was investigated whether CPR, LBR and time-to-pregnancy could be improved by analyzing the gene expression profile of three predictive genes in the cumulus cells, compared to patients with morphology-based embryo selection only...
