Associations of maternal circulating 25-hydroxyvitamin D3 concentration with pregnancy and birth outcomes
2015
Objective To investigate the association of maternal circulating 25-hydroxyvitamin D3 [25(OH)D3] concentration with pregnancy and birth outcomes. Design Prospective cohort study. Setting Four geographical areas of Spain, 2003–2008. Population Of 2382 mother–child pairs participating in the INfancia y Medio Ambiente (INMA) Project. Methods Maternal circulating 25(OH)D3 concentration was measured in pregnancy (mean [SD] 13.5 [2.2] weeks of gestation). We tested associations of maternal 25(OH)D3 concentration with pregnancy and birth outcomes. Main outcome measures Gestational diabetes mellitus (GDM), preterm delivery, caesarean section, fetal growth restriction (FGR) and small-for-gestational…
Myoinositol supplementation in the treatment of gestational diabetes mellitus: effects on glycaemic control and maternal-foetal outcomes.
2022
Abstract Background Gestational diabetes mellitus (GDM) is defined as glucose intolerance with onset during pregnancy. It is characterized by high risk of adverse outcomes for the mother and the foetus, if not adequately controlled. The aim of the study was to evaluate the effects of 4000 mg of myoinositol supplementation in women with GDM on maternal-foetal outcomes, compared to controls. Methods A cohort of 330 women with GDM, 150 supplemented with myoinositol and 180 controls were enrolled. Clinical and metabolic parameters and the prevalence of maternal and foetal complications were assessed. Results The same number of women in the two groups started insulin as additional therapy. Women…

Effectiveness of progestogens to improve perinatal outcome in twin pregnancies : an individual participant data meta-analysis
2015
Background In twin pregnancies, the rates of adverse perinatal outcome and subsequent long-term morbidity are substantial, and mainly result from preterm birth (PTB). Objectives To assess the effectiveness of progestogen treatment in the prevention of neonatal morbidity or PTB in twin pregnancies using individual participant data meta-analysis (IPDMA). Search strategy We searched international scientific databases, trial registration websites, and references of identified articles. Selection criteria Randomised clinical trials (RCTs) of 17–hydroxyprogesterone caproate (17Pc) or vaginally administered natural progesterone, compared with placebo or no treatment. Data collection and analysis I…
Intimate partner violence and perinatal health: a systematic review
2019
Background Physical, psychological, and sexual intimate partner violence (IPV) has been described in the literature as different types of IPV experienced by women during pregnancy all over the world. Objectives To review and summarise systematically the empirical evidence on the links between IPV during pregnancy and the perinatal health of mothers and fetuses/neonates. Search strategy MEDLINE (Ovid), CINAHL, Embase, Nursing@ovid (Ovid), and LILACS were performed (2008-2018). Selection criteria Observational studies that examined perinatal health outcomes (i.e. pre-term birth, low birthweight, miscarriage, perinatal death, and premature rupture of membranes) in pregnant women exposed to IPV…
Association of Gestational Weight Gain With Adverse Maternal and Infant Outcomes
2019
Importance: Both low and high gestational weight gain have been associated with adverse maternal and infant outcomes, but optimal gestational weight gain remains uncertain and not well defined for all prepregnancy weight ranges. Objectives: To examine the association of ranges of gestational weight gain with risk of adverse maternal and infant outcomes and estimate optimal gestational weight gain ranges across prepregnancy body mass index categories. Design, setting, and participants: Individual participant-level meta-analysis using data from 196 670 participants within 25 cohort studies from Europe and North America (main study sample). Optimal gestational weight gain ranges were estimated…
Obstetric and Neonatal Outcome of Pregnancies Fathered by Males on Immunosuppression After Solid Organ Transplantation
2015
Immunosuppressive drugs may influence spermatogenesis, but little is known about outcome of pregnancies fathered by transplanted males. We estimated risk of adverse outcomes in pregnancies (with data after the first trimester) fathered by males that had undergone organ transplantation and were treated with immunosuppression. A population-based study, linking data from the Norwegian transplant registry and the Medical Birth Registry of Norway during 1967-2009 was designed. All Norwegian men undergoing solid organ transplantation were included. Odds ratios for major malformations, preeclampsia, preterm delivery (<37 weeks) and small-for-gestational-age were obtained using logistic regression.…
A distinct subset of HLA-DR+-regulatory T cells is involved in the induction of preterm labor during pregnancy and in the induction of organ rejectio…
2010
Regulatory T cells (Tregs) are known to suppress alloimmune responses during pregnancy and post organ transplantation. We demonstrate that a distinct subset of FoxP3(+)DR(+)-Tregs among the total CD4(+)CD127(low+/-)CD25(+)-Treg cell pool is critically involved in preterm labor induction and kidney transplant rejection as well. Compared to healthy pregnancies and non-rejecting kidney recipients, we found that the percentage of the FoxP3(+)DR(+)-Treg subset was not reduced, but that the level of HLA-DR expression of such Tregs was strongly diminished in preterm laboring women and in patients with acute renal allograft rejection. In addition, both patient collectives showed a significantly red…
Increased doses of vaginal progesterone for the prevention of preterm birth in twin pregnancies: a randomised controlled double-blind multicentre tri…
2012
Objective Previous trials have shown little benefit for preventing preterm birth in twin pregnancies using 90–200 mg of daily vaginal natural progesterone. Higher doses have not been tested. Our aim was to determine the efficacy and safety of two different daily doses of vaginal natural progesterone (200 and 400 mg), compared with placebo, for preventing preterm birth in unselected twin pregnancies. Design Randomised controlled double-blind multicentre trial (1:1:1). Setting The study was carried out in five university centres from Valencia, Murcia and Alicante (Spain). Population Women with dichorionic diamniotic twin pregnancies. Methods The women self-inserted two vaginal pessaries …
Incomplete Gestation has an Impact on Cognitive Abilities in Autism Spectrum Disorder
2019
Extreme prematurity is known as a risk factor for autism spectrum disorder (ASD). However, the association between prematurity and ASD, for children born moderately and late preterm (MLPT) and those born early term (ET), is less established. This retrospective study aimed to characterize the phenotypic characteristics (i.e. behavioral profile and cognitive abilities) of 254 children with ASD, between 3 and 15 years of age, born MLPT (19 children), ET (60 children) and full term (175 children). MLPT and ET births do not modify ASD symptomatology, but modify cognitive development. The results highlight that incomplete gestation, i.e., MLPT or ET, has a negative impact on both verbal and nonve…
