2019
ObjectiveTo assess the separate and combined associations of maternal pre‐pregnancy body mass index (BMI) and gestational weight gain with the risks of pregnancy complications and their population impact.DesignIndividual participant data meta‐analysis of 39 cohorts.SettingEurope, North America, and Oceania.Population265 270 births.MethodsInformation on maternal pre‐pregnancy BMI, gestational weight gain, and pregnancy complications was obtained. Multilevel binary logistic regression models were used.Main outcome measuresGestational hypertension, pre‐eclampsia, gestational diabetes, preterm birth, small and large for gestational age at birth.ResultsHigher maternal pre‐pregnancy BMI and gesta…
L-citrulline ameliorates pathophysiology in a rat model of superimposed preeclampsia
2021
AbstractPreeclampsia, characterized by hypertension, proteinuria, and fetal growth restriction, is one of the leading causes of maternal and perinatal mortality. By far, there is no effective pharmacological therapy for preeclampsia. The present study was conducted to investigate the effects of L-citrulline supplementation in Dahl salt-sensitive rat, a model of superimposed preeclampsia. Parental DSSR were treated with L-citrulline (2.5 g/L in drinking water) from the day of mating to the end of lactation period. Blood pressure of the rats was monitored throughout pregnancy and markers of preeclampsia were assessed. Endothelial function of the pregnant DSSR was assessed by wire myograph. L-…
Preliminary reference intervals of Glycated Albumin in healthy Caucasian pregnant women
2021
Abstract Background and aims Glycated albumin (GA) could represent a useful biomarker in pregnant women for diagnosing and monitoring gestational diabetes mellitus (GDM). The establishment of reference intervals (RI) is mandatory before assessing its clinical usefulness. The RIs of GA in healthy pregnant women are not well defined. The aim of the current study was to establish the RI in a cohort consisting of Caucasian pregnant women without overt diabetes mellitus or gestational diabetes mellitus. Methods The study included 183 healthy pregnant women. GA was measured on plasma by an enzymatic method (quantILab Glycated Albumin, IL Werfen, Germany). The RI was calculated by the non-parametr…
Posters Early pregnancy P01First trimester normograms for a wide variety of ultrasound, hemodynamic and serum parameters
2000
Background The aim of the study was to assess prospectively the evolution of multiple clinical parameters throughout the first trimester of pregnancy. Method A transvaginal ultrasound examination and a blood test was weekly performed until the 13th gestational week in a group of healthy volunteers. A total of 25 spontaneously conceived singleton pregnant women with good pregnancy outcome finally completed the study. The evolution of 10 transvaginal ultrasound parameters, 5 Doppler measurements and 6 serum parameters was studied. Results An increasing trend with advancing gestation was evident for the mean gestational sac (MSD) and amniotic sac (AS) diameters, trophoblastic rim, CRL and seru…
P20Early membrane funnelling may occur from 16 weeks onwards and carries a worse prognosis
2000
Background Sonographic screening for cervical incompetence during pregnancy is currently a routine procedure. However, no consensus exists on the optimal gestational age to perform such screening. Method Serial transvaginal ultrasound examinations of the uterine cervix were routinely performed from 12 weeks onwards. The screening was considered positive when membrane funnelling was present or the cervical length was < 2 cm. Therapeutic measures included bed rest, antibiotics, tocolytic treatment and a modified McDonald's cervical suture (up to 25 weeks). Results Membrane funnelling was detected between 16 and 22 weeks (group A) in 9 women (31%); between 23 and 28 weeks (group B) in 11 women…
Abdominale, perineale und vaginale sonographische Diagnose der Zervikalinsuffizienz
2008
In patients with cervical incompetence, the diagnostic efficiency of abdominal, perineal and vaginal sonography was compared. 73 patients, who were divided into three groups, were examined: Group A (n = 50) control group, Group B (n = 11) normal pregnancies, Group C (n = 12) pregnancies with demonstrated cervical incompetence. According to our results, using vaginal sonography, only the incompetent pregnancies showed significant shortening of the cervical length. Characteristic scans were also obtained (membrane herniation) which were useful in diagnosis and control in the performance of cerclage.
Gimema Registry of Conception/Pregnancy in Adult Patients Diagnosed with Chronic Myeloid Leukemia (CML) Treated with Tyrosine Kinase Inhibitors (TKIs)
2014
Abstract The management of patients with chronic myeloid leukemia (CML) during pregnancy is a matter of continuous debate. The introduction of the tyrosin kinase inhibitors (TKIs) in clinical practice has dramatically changed the prognosis of CML patients. Patients diagnosed in chronic phase can expect an excellent disease control and a normal lifespan. Issues relating to fertility and pregnancy must be introduced at diagnosis. Different reports were published in patients conceving/getting pregnant during Imatinib treatment, while there are only sporadic data about other TKIs. The GIMEMA CML working party has started a retrospective and prospective study to describe all female pregnancies/m…
Standard international recommendations for gestational weight gain: suitability for our population
2020
Background: gestational weight gain (GWG) is one of the most commonly used indicators in prenatal care, and probably the most influential factor in perinatal outcomes. Objective: to determine the extent to which the GWG of pregnant women from the Ribera Health Department (Valencia) meets GWG international standards as recommended by the U.S. Institute of Medicine (IOM). Methods: a retrospective observational study of a sample of 4,361 women who gave birth at Hospital Universitario de la Ribera between January 1, 2010 and December 31, 2015. Pregnant women were classified according to GWG international recommendations: adequate weight gain, above and below. Results: a higher GWG increases the…
F117Hystero-embryoscopic findings in early nonviable pregnancies
2000
Background A high proportion of early pregnancy losses are associated to abnormal embryo development. However, chromosomal analysis of routine curettage samples are of limited value; and histopathological examinations of the embryos are rarely performed in clinical practice. Method A transcervical hystero-embryoscopy was performed prior to the curettage in 31 nonviable first-trimester pregnancies and a control group of 5 early terminations of pregnancy. In the study group, the estimated gestational age according to the ultrasound findings was 6.7 (4–9) menstrual weeks. Direct biopsies of different gestational structures were taken during the endoscopic procedure. Results In nonviable pregna…
CK-BB as indicator of prenatal brain-cell injury in fetuses with absent or reverse end-diastolic flow velocities of the umbilical arteries
1994
The purpose of this study is to determine the levels of brain type isoenzyme of creatine kinase (CK-BB) as a possible indicator of a pre-existing intrauterine brain-cell damage in cord blood sera of fetuses with preceding absent or reverse end-diastolic flow velocities of the umbilical arteries (AREDFV). CK-BB isoenzyme activities were determined in umbilical cord sera of 13 newborn infants with preceding AREDFV and in 14 fetuses with low end-diastolic flow velocities (LEDFV) of the umbilical arteries. 50 newborn infants with elective cesarean section and normal umbilical artery blood flow velocity waveforms were used as controls. Two-tailed Student's t-test and Fischer's exact test were us…
